Observation principles: Ensure naturalness when observing, without affecting the psychology of students, teachers and the teaching and learning process.
How to proceed:
- Observe students during the test from their demeanor and posture
to the manifestations
- Observing students in class: we conducted class observations in Vietnamese and Math subjects, including both new lecture and practice classes. The total number of classes we observed was 10. Each class lasted 35 minutes.
- Observing students during political classes: Students participating in political classes are monitored throughout the entire course. In each class, we observe students' performance from the time they arrive at the political class until they return to the regular class (behavior, speech, attitude, reaction speed, number of errors, number of practice sessions, etc.). The total number of political classes we observe is 20, each lasting about 90 minutes.
Information observed in students is carefully recorded according to a pre-prepared observation report form.
2.2.4.2. Interview method
Purpose: To collect, supplement, check and clarify the collected information.
obtained from large-scale field surveys.
Interview content: The interview content is clearly prepared according to the issues that the researcher is interested in, including: Information about the student, family circumstances, student's relationship with friends and teachers; academic performance, discipline and study habits in class and at home, student's history...
Interview principles : In in-depth interviews, we ask open-ended questions so that parents and teachers can answer directly or indirectly according to their subjective wishes. The interview is conducted as a conversation, exchanging about the student's study life, activities at school and at home.
Request :
+ Be tactful and tactful when dealing with the subject.
+ The content of the discussion is based on the content of building a psychological portrait of the student.
+ Record the subject's expressions and responses.
How to do :
* With students: Talk to individual students during breaks to dig deeper into specific issues.
* With teachers: Not only discuss with the homeroom teachers of the students selected for research, but also discuss with the teachers in charge of the Team and the school's Board of Directors.
* For parents: Talk to some parents to learn more about students.
student activities, studies and other necessary information
2.2.4.3. Product research methods
Study the test results, assignments, tests, and exams of students to collect data reflecting the knowledge acquisition ability of CPTRG high school students and examine the changes of students to supplement the analysis of experimental results.
How to proceed : Review students' notebooks, exercise books, and grade books.

2.2.4.4. Expert method
Purpose: To consult with experts in the fields of psychology, education, and elementary school teaching methods directly related to the research content of the topic.
Method: Consulted with some psychologists and experienced primary school teachers on the selection of exercises to be used to test the assessment and compensation effects in the reading comprehension DCT for CPTRG primary school students.
2.2.4.5. Case study method
Purpose : The use and implementation of the case study method aims to describe the reading comprehension difficulties of a specific CPTRG HSTH and the
The changes obtained after the effects of DCT reading comprehension. The case study results supplement and further illustrate the research results obtained from quantitative research methods.
Case studies were conducted with the following contents :
+ Build a portrait of HSTH CPTRG in terms of:
- Information and characteristics about the individual student and family involved.
- Clinical images of students
- Psychological image of students
- Neuropsychological images of students
+ Describe the process and analyze the changes under the influence of the factors
compensation in experimental DCT reading comprehension
The case study was conducted on four students :
1) Nguyen Minh Ph. N, born in 2006, gender: Male, 2nd grade student,
Hong Son Primary School, Vinh City, Nghe An Province
2) Nguyen XT, born in 2006, gender: Male, 2nd grade student at Hong Son Primary School, Vinh City, Nghe An Province
3) Hoang D.Th, born in 2005, gender: Female, 2nd grade student at Hong Son Primary School, Vinh City, Nghe An Province
4) Nguyen Ng. A, born in 2006, gender: Female, 2nd grade student at Hong Son Primary School, Vinh City, Nghe An Province
How to proceed
Among the CPTRG students selected for research, we only selected students whose profiles fully reflected information about the entire research process of the thesis topic (students who participated fully from the beginning to the end of the research process) for case study. The case studies described the entire process in detail, on that basis, we considered and evaluated the changes of CPTRG students under the impact of DCT reading comprehension.
2.2.4.6. Experimental method
This is the basic research method of the topic. For the purpose of research, the topic conducts two types of experiments including deterministic experiments and formative experiments (will be presented specifically in sections 2.3 and 2.4).
2.3. ORGANIZATION OF EXPERIMENTAL DETERMINATION
This phase was conducted between September 2013 and November 2013.
2.3.1. Purpose
- Detecting CPTRG HSTH studying in normal classes at home
elementary school
- Study the CPT mechanisms in HSTH CPTRG and the relevance of those mechanisms to reading comprehension
2.3.2. Tasks
- Conduct screening to detect CPTRG students using Gille test
- Conduct in-depth diagnosis to determine the mechanism causing reading comprehension difficulties using the Luria-90 test
2.3.3. Content
- Assess the intellectual development level of HSTH to identify children with CPTRG
- Determine the CPT zoning of functional areas in HSTH CPTRG and classify based on zoning
- Analysis of neuropsychological syndromes to clarify the manifestations of reading comprehension difficulties in CPTRG forms
2.3.4. How to proceed
To study this content, the thesis chooses the method of measurement.
Experimental determination is conducted in 2 steps:
Step 1: Screening - detecting CPTRG HSTH
Purpose : Screening to detect students with cognitive problems (IQ at CPTRG level) and to exclude cases of normally developing students and intellectual disabilities.
Content: assess students' intellectual level and knowledge through assessment of comparison, classification, perception of quantity, weight, size, space, time, ability to perceive objects, ability to reason logically, ability to generalize visually in exercises.
Tools: In the thesis topic, Gille test is used for research purposes.
Screening and detection of students with cognitive problems (IQ at CPTRG level).
Gille Multiple Intelligence Test was chosen as the research tool in this step for the following reasons:
+ The Gille Test can assess the intellectual level and knowledge of students from 6 to 12 years old through assessing the operations of comparison, classification, perception of quantity, weight, size, space, time, the ability to perceive objects, the ability to reason logically, the ability to generalize visually - these are also basic and important operations and abilities for learning and acquiring knowledge in primary school students. Therefore, the content of the exercises of the Gille Test is suitable for the content that needs to be researched (used to select students with cognitive problems) and the research object of the topic (primary school students).
+ The Gille Test was introduced and adapted in the study of Vietnamese children's intelligence since 1990. All the things described in the Gille Test exercises are close to the daily life of Vietnamese children.
The Multiple Intelligence Test was developed by French psychologist Ron Gille in 1944, based on the theory of child cognitive development of J. Piaget. Later, the Gille Test was standardized by psychologists of the French National Population Commission on 9,500 children from 6 to 14 years old, including children of farmers, workers, merchants, high-level intellectuals... over a period of 10 years. In 1954, the Gille Test was widely used in France and some countries to diagnose the intelligence of children from 6 to 12 years old. Since 1990, many research projects have used the Gille Test as a means to study the psychology of Vietnamese children.
The content and structure of the Gille Test consists of 62 exercises [25]. Analyzing the content and function of these exercises, they can be divided into 5 groups as follows:
A/ Group of exercises to explore children's ability to establish spatial relationships between objects.
Essentially, it is to study the ability to form symbols of the spatial position of an object in relation to other objects or to the student himself. The relationships mentioned here are the categories: inside - outside; above - below; right - left... The system of exercises is structured according to the principle from easy to difficult, from one relationship to a complex of relationships between objects.
B/ Group of exercises to learn generalization operations:
These are exercises to determine the ability to classify (group and subtract) of the subjects. Their requirements are that children must have knowledge through life experience about the uses, properties, and shapes of objects, be able to identify them, compare and contrast objects with each other, and then group (generalize) them into a certain class of objects with common functions and signs, or eliminate different signs and functions of objects in the same class to form a new class. Finally, symbolize those classes with certain language symbols.
C/ Group of exercises to learn analytical skills:
These exercises are designed to test children's ability to integrate their perception of reality and their thinking, and thus their analytical abilities. They are structured on several levels. First, they measure the ability to analyze a simple, familiar object to find the missing part of the object (and its perceptual image); then they add this missing part to the perceptual image to create a complete image of the object.
At a higher level, the object being analyzed has a more complex structure, with many parts connected to each other according to certain rules. Therefore, to solve these exercises correctly, the participants must not only perceive, analyze with images and assemble them, but also have a thinking element to determine the logic of the object and the relationship between the missing part and the other parts and the overall whole.
The highest level of exercises in this group is the analysis of the structure of pictures with many objects related to each other according to a certain theme. The task of determining the missing part of the picture is much more difficult than the previous levels.
Thus, the three levels of exercises in this group represent three levels of development of analytical operations in students, in which levels 2 and 3 are qualitatively different from level 1 - the level of perceptual analysis.
D/ Group of exercises to learn reasoning ability:
This group includes tasks that require children to analyze perceptual images to
comment and infer the structural direction of things according to a certain logic. Level
The low point in this system of exercises is that the conclusions of the subject are drawn in accordance with the image of perception (direct reasoning in the forward direction).
The higher level requires the conclusion to go beyond the perceptual image to relate to the existing life experience, selecting from that life experience those things that are consistent with one's judgment. The highest level of these exercises is the logical deduction of the structure of things in a certain overall picture.
E/ Group of exercises to explore children's ability to establish number relationships, including exercises to identify mathematical relationships (more than, equal to, less than), mental calculation skills and doing simple addition and subtraction based on the drawings in the exercises.
Thus, through the way of conducting exercises and the test results of students, we can evaluate the level of intelligence and knowledge of students, learn the operations of analysis, comparison, generalization, symbols, concepts of numbers, weight, spatial relationships, perception ability and the relationship between thinking and perception, calculation and reasoning ability of students, from which we can determine the general level of intellectual development. The test scores are converted and compared with the Weschler classification table to allow screening and selecting a list of students with IQ standard scores between 70 and 85.
How to conduct: The Gille test is conducted on groups of 10-15 students right at school, in the following order:
+ Distribute a worksheet of 62 exercises to each student.
+ Instruct students to fill in all required items on the first page.
+ Give clear, natural instructions for each exercise without suggestions or corrections in the instructions or students' work.
Research subjects and locations:
The screening was conducted on students classified as poor learners. These were students referred by schools, including 517 first and second graders in the following areas:
- Hanoi city includes:
+ Yen Xa Primary School: 34 students
+ Tan Trieu Primary School: 38 students
+ Khuong Dinh Primary School: 32 students
- Vinh City - Nghe An includes:
+ Hong Son Primary School: 45 students
+ Hung Binh Primary School: 46 students
+ Trung Do Primary School: 47 students
+ Ben Thuy Primary School: 48 students
+ Truong Thi Primary School: 45 students
+ Ha Huy Tap 2 Primary School: 42 students

- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in people's daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone company's network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

Similar to sending messages, those with an average message receiving rate (from 3-10 messages/day) accounted for the highest percentage of ~ 55%, followed by those with a high number of messages (over 10 messages/day) ~ 24% and those with a low number of messages received daily (under 3 messages/day) remained at the bottom with 21%.

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)

- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in peoples daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone companys network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

Similar to sending messages, those with an average message receiving rate (from 3-10 messages/day) accounted for the highest percentage of ~ 55%, followed by those with a high number of messages (over 10 messages/day) ~ 24% and those with a low number of messages received daily (under 3 messages/day) remained at the bottom with 21%.

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)
