Improve the quality of TVHN activities in schools where students are studying.
In addition to the main tool of opinion polls, interview forms were also used for managers, teachers and students. The content of the interview focused mainly on: the difficulties that target groups encountered in the process of TVHN; the causes of the shortcomings leading to the current management of this activity; the suggestions of managers, teachers as well as the wishes of students in promoting the management of TVHN activities in schools today.
2.2.4. Investigation method
For the questionnaire survey, the forms were distributed directly to teachers, managers and students to complete at the school and immediately returned to the collaborator (colleague of the thesis author). At the same time, they were sent by post to teachers, managers and students.
When investigating by interview: Questions are asked to each teacher, manager, student and each group of 4 students, then listened to and recorded.
2.2.5. Conduct investigation
For questionnaire surveys , conduct the survey according to the following procedure:
Step 1. Identify and select necessary content from theoretical basis, practical experience and issued documents related to TVHN activities to develop survey content using questionnaires and interviews to determine the current status of TVHN activities for high school students in the Southeast provinces.
Step 2. Select research area and survey subjects
Research area: 3 provinces in the Southeast region: Binh Duong, Ba Ria
- Vung Tau and Dong Nai, total 96 high schools. Of which, Binh Duong includes: 21 high schools, Ba Ria - Vung Tau: 27 high schools and Dong Nai has 48 high schools.
Survey subjects: In order to ensure that the survey sample is representative, the thesis conducts sampling according to statistical probability theory. The form of random sampling with 20% of the total 96 high schools is representative schools in 3 provinces of the Southeast region. In each selected school, managers, teachers and students are selected as survey samples at a rate of 60% (See table 2.3).

- 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)

Step 3. Compile criteria for assessing the current situation based on the theoretical framework developed in Chapter 1. Form scales for the levels of suitability and implementation of TVHN activity management.
Step 4. Determine the content of the questionnaire, probe with a number of closed, open and combined questions about TVHN activities in high schools in the Southeast region. Complete the questionnaire, evaluation criteria and scale to create a poll for 02 groups of survey subjects: managers, teachers and students.
Step 5. Organize a pilot survey of the questionnaire at Thanh Binh High School. Process the pilot survey results and then edit the questions in the questionnaire. Conduct a survey by asking a large number of people. Distribute survey forms directly to managers, teachers, staff and students from February to April 2017. Finally, analyze and evaluate the results from the collected survey forms.
For interview investigation
Collect, supplement, check and clarify the information obtained from the questionnaire survey to be able to honestly and objectively assess the current situation of TVHN management activities in high schools in the Southeast region. This set of interview questions helps the thesis author have a view from three sides: managers, teachers and students.
Step 1. Develop interview outline and questionnaire.
Step 2. Schedule an appointment with each principal, vice principal, homeroom teacher, subject teacher, technical education teacher and student affairs officer. The total number of people giving their opinions and answering the interview was: 10 managers, 15 teachers and 44 students (interviewed in groups, 4 students/group) from 20 high schools in 3 provinces in the Southeast region (Binh Duong, Ba Ria - Vung Tau and Dong Nai).
Step 3. Direct discussion or telephone/email interview with each individual. Interviews were conducted from mid-June to August 2017. Interview content was recorded fully and in detail.
Step 4. Analyze, synthesize and compare interview responses to draw conclusions.
2.2.6. How to process and evaluate investigation results
For quantitative data
The results of quantitative criteria obtained from the main survey instrument are the Questionnaire.
opinion poll. To have specific calculation data, the collected data will be encoded into numbers, the answered questions will be encoded from number 1 to number 5, the unanswered questions will be encoded with number 0. The scales mainly used in the survey forms are the nominal scale to determine the name, gender and some characteristics of the survey subjects; the hierarchical scale and the interval scale to calculate parameters in descriptive statistics such as average; Variance; Standard deviation (SD); Frequency; Range; Sample mean error; Percentage. To facilitate the evaluation and analysis of data in a reasonable and scientific way, the information collected from the opinion poll forms on the current situation is conventionally based on the average value in the Likert scale according to 5 levels, Value
calculated distance = max − 𝑚𝑖𝑛 = 5−1 = 0.8 . Then:
5 5
From 1.0 point - 1.8 point: Poor (corresponding to the answer level: Not important/ Never/ Not done/ Poor/ No influence/ Dislike/ Lack of confidence).
From 1.81 points – 2.60 points: Weak (equivalent to the answer level: Less important/ Rarely/ Not achieved/ Very little influence/ Very little liking/ Very little confidence).
From 2.61 points - 3.40 points: Average (corresponding to the answer level: Normal/ Occasionally/ Satisfactory/ Average/ Little influence/ Little liking/ Little confidence).
From 3.41 points - 4.20 points: Fair (corresponding to the answer level: Important/ Regular/ Fair/ Influence/ Like/ Confident).
From 4.21 points – 5 points: Good (corresponding to the answer level: Very important/ Very often/ Good/ Very influential/ Very like/ Very confident).
For qualitative data
In the case of interviews with managers and teachers, the data is divided into the following groups of opinions: 1) About the difficulties and shortcomings of TVHN activities in schools; 2) The results achieved and not achieved in TVHN activities in the last 3 years of the school; 3) The basic causes leading to the current status of TVHN management activities in schools; 4) Proposing and recommending measures to promote the management of TVHN activities at schools.
For the case of student interviews, the data is classified according to: 1) During TVHN, what difficulties or shortcomings did you encounter (such as understanding the chosen career; importance according to each factor of the labor market; necessity of preparation)?
2) Expressions of interest in TVHN activities, satisfaction with consulting organizations in meeting their TVHN needs); 3) Students' wishes from principals, vice principals, homeroom teachers, subject teachers, TVHN officers, youth union... to improve the quality of TVHN activities in schools today.
- This qualitative data is processed using a logical method: arranging answers with similarities and differences. Then analyzing, arguing and making comments as a basis for evaluating the current status of TVHN activities and TVHN activity management in 20 high schools in the Southeast region. Information collected from interviews when cited in the thesis content will be encoded to ensure the confidentiality and objectivity of the interview opinions.
2.3. Investigation results
Based on the analysis of data from the questionnaire in Appendix 1.1 (for managers and teachers), Appendix 1.2 (for students) and from interviews in Appendix 1.3, 1.4 on the current status of TVHN and management of TVHN activities for high school students in the Southeast provinces, the following results were obtained:
2.3.1. Current status of career counseling activities for high school students in the Southeast region
2.3.1.1. Awareness of the importance of career counseling activities
The results of the survey on the awareness of managers, teachers and students about the importance of TVHN activities are summarized in Table 2.4, showing that the average score of each answer is quite high and relatively even. This proves that both groups of subjects have understood and recognized the meaning, role and importance of TVHN activities .
Table 2.4. Current status of awareness about the importance of TVHN activities
TT
Level of importance | Managers and Teachers | HS | |||||||
Number quantity | Ratio % | Average | DLC | Number quantity | Ratio % | Average | DLC | ||
1 | Not important | 0 | 0.0 | 4.69 | 0.54 | 13 | 0.5 | 4.03 | 0.46 |

4 | Important | 114 | 22.9 | 2007 | 84.9 | ||||
5 | Very important | 364 | 73.2 | 240 | 10.2 | ||||
Based on the general average and standard deviation in the responses of each group of subjects, there is no contradiction or difference between the views of managers and teachers (general average: 4.69; standard deviation: 0.54) and students (general average: 4.03; standard deviation: 0.46) in high schools on the importance of TVHN activities. However, managers and teachers tend to appreciate the importance of TVHN activities more than students. This is understandable because managers and teachers are the school leaders and those who directly do TVHN work and will be fully aware of the urgency of this activity.
2.3.1.2. Career counseling needs of high school students in the Southeast region
The expression of TVHN needs of high school students in the Southeast region is shown through:
Level of students' understanding of the labor market and chosen career
The survey results recorded in Table 2.5 show that among the 7 factors, students only have “understanding” about the factor “ vocational training system”, accounting for 56.3%. Obviously, students have proactively learned about the profession they intend to choose at many different vocational training facilities to have a suitable school choice.
Table 2.5. Level of students' understanding of the labor market and intended career

% | 2.1 | 54.8 | 35.8 | 3.3 | 4.0 | ||
Meanwhile, students have “little understanding” of the world of careers, accounting for 50.7%; the general labor market demand for the chosen career, accounting for 64.3%; the purpose, meaning, and specific work related to the career, accounting for 50.2%; their own capacity (qualities, skills) suitable for the career, accounting for 54%; their psychological characteristics (personality, temperament, health conditions, etc.) with the requirements of the career, accounting for 56.7% and the career development direction for themselves, accounting for 54.8%.
Discussing and talking with leaders of high schools in the Southeast region about this issue, we learned:
- According to the Management Board of Nhon Trach High School: The work of TVHN, especially the selection of majors, blocks, and subjects other than the compulsory subjects in the National High School Exam for admission to colleges and universities of students is currently being implemented quite flexibly by schools. However, for students, guiding and preparing the young generation in both mindset and skills so that they can be ready to enter the workforce or create their own jobs in the social professions that need to develop, while at the same time being suitable for the interests and abilities of the individual students is really a "difficult problem" when we ourselves do not have much information about the planning of human resource needs in the locality, or information with a practical basis about the needs of future labor professions.
- The managers of Dac Lua High School, Nguyen Dinh Chieu High School, Nhon Trach High School and Phuoc Thien High School shared: Every year, when the university entrance exam is approaching, universities in and outside the province will contact the school to coordinate in organizing admissions counseling for their students. The school's current student counseling work only stops at organizing career introductions for students to consider choosing or coordinating with local training institutions to provide counseling and introductions to the training majors of that unit, but the ability of the current annual counseling programs cannot answer all the questions of students and cannot help them orient their future careers.
From the survey results combined with the above interviews, it can be seen that 50% of the surveyed students have little understanding of the labor market and the career they intend to choose. It seems that they choose their career entirely based on their feelings. In other words, the school has not provided students with enough information about the labor market and the world of careers, helping them understand their own psychological, physiological, and capacity characteristics, helping them to partly resolve their confusion when choosing a career. The school's career guidance activities have not met the career guidance needs of students.
Subjects influencing students' career choices
Although they are properly aware of the role of this activity in high school and proactively learn about the intended career at many different vocational training institutions to choose the right school, when asked about "the subjects that influence students' career choice", up to 81.2% of students chose "family" as the most influential.

- 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)
