1. Introduction

The ages of 20-30 are the marriage, childbirth, and childcare. It is the time to achieve intimacy and productivity as a life task and this period also plays a very important social role as the most socially active period [1-2]. People often say those periods are often the ones who set the foundations for comfortable life through various fluent opportunity. In addition, the happiness of the 20-30s has a great influence on the family and social role in the whole life, it could be a basis for preparing the happy senior age [3]. However, the present 20-30 generations in Korea are pouring out words that are pessimistic about their situation [4]. The so-called ‘Sampo generation’ implies such a meaning. ‘Sampo generation’ is giving up on three things; giving up on love, marriage, and childbirth [5]. This is a very unfortunate phenomenon at a time when the foundation of life should be sincerely initiated.

Due to the global economic downturn and extreme youth employment crisis, problems have arisen in many countries such as Japan and Europe. In Europe, young people who are hard to guarantee their future due to unstable employment conditions and low wages are sometimes referred to as ‘IKEA generation’ [6]. Korea is also accelerating this problem. The ‘Sampo generation’ problem, which is now in its 20s and 30s, will be linked to serious social problems. So far, analyzing the contents of these problems, many 20s start with the burden of reimbursement of student loans after graduating from college. Also, they are reported to have a considerable burden of preparing for employment due to a job competition. In addition, a marriage requires a house to live in. Nevertheless, excessive house prices are very burdensome, so they have given up on dating or marriage in the 20-30’s. People have task to solve at heir age, and when they are not doing this, they feel unhappy, and situations like those in their 20s and 30s have caused them to feel unhappy.

The concept of happiness in various fields has been described as ‘quality of life’ or ‘subjective well-being’ and also happiness is used in the quality as a concept such as ‘subjective of life’ or ‘subjective well-being’ [7- 9]. In other words, happiness is a subjective feeling that enhances the quality of life. Only a few decades ago, our economy status was not as good as it is now. But today’s younger generation is feeling more unhappy about their lives than it was when economic conditions were difficult, and they are abandoning marriage and giving birth due to such anxiety. If so, the economic conditions and employment competition that have been studied do far may not be all of the unfortunate causes of the younger generation. According to a research by JA Kim et al., [7]. The research emphasized that health promoting behavior affect emotional happiness in the elderly people.

Health promotion is defined in the Ottawa Charter as “the process of cultivating the ability of people to increase their control over their health and improve their health” [10-1]. And the goal of health promotion is to give everyone the same opportunity and resources to ensure that everyone reaches their full potential for health. According to JA Kim et al., the quality of life is emphasized to practice and maintain health promoting behavior. A more detailed definition of health promoting behavior is the definition of Walker and Pender. Walker and Pender (1987) defined health promotion behaviors as activities to improve a healthy lifestyle, and five categories of health promoting activities were classified as health responsibility or personal hygiene, nutrition habit, exercise, stress management, social relation, and self-actualization [12]. Personal hygiene could be defined as an act of maintaining cleanliness of body such as personal hygiene. In the concept of health promotion, ‘nutriton’ is to maintain a person in the best condition by eating a balanced diet which can reduce the person’s risk of heart disease, diabetes, osteoporosis and some cancers. Exercise is an important health promotion activity that maintains health by promoting strengthening of muscles and flexibility, including prevention of cardiovascular disease. Health promotion emphasizes prevention; Stress management is an important health promotion. Stress management can also be sen as important in promoting mental health by strengthening positive mentality. In addition, stress management can effectively reduce chronic diseases. In a recent competitive society, people are exposed in various social environments whether they want or not, in this social environment, formation of social relations is an important factor in forming the intimacy and support of social relations. The social environment is related to behavioral mechanisms and immune function [13-14]. In this concept, social relations are related to behavioral mechanisms and immune function. In this concept social relations are related to health promotion. Self actualization is to maximize potential by satisfying one’s own neds. In other words, it means to promote health as much as possible. Looking at the above studies, the ultimate goal of health promotion focuses on physical and mental emotional well-being. Recently, Korea is expressing its unhappy life in the 20s and 30s who are engaged in socially active activities, so that hey could say ‘Sampo generation’ rather than happiness. happiness is a subjective concept and the discussions about these expressions are diverse. However, it could be said that the negative expressions of the present age, which developed economically than the past, solve the absolute poverty, but the relative poverty has increased.

In the 20s and 30s, it is an important time to start a new life as an adult, and it is also a time to form new families such as love, marriage, and childbirth. This period is also the most active period of our society, and its happiness will have a considerable impact on society as a whole. The purpose of this study was to identify the general characteristics of the 20-30 age groups and to investigate the effect of health promoting activities on emotional happiness. Through this research, basic data of realistic program’s developing to solve their real problem will be prepared. Therefore, the purpose of this research is as follows. First, identify the general characteristics of people in their 20s and 30s. Second, analyze the correlation between health promotion behavior and emotional happiness. Third, determine the Effect of Health Promotion Behavior on Emotional happiness.

2. Research Methods

2.2. Research tools

2.2.1. Health Promotion Behavior

The health promoting behavior measurement tool for this study was developed by Walker et al., [12]. A total 47 items were composed of personal hygiene, nutrition habit, substance abuse, exercise, stress management, and self-actualization. 1 point was interpreted as ‘not at al’, 2 points as ‘sometimes’, 3 points as ‘often’, and 4points as ‘always’. The higher the score, the higher the health promoting behavior. The reliability of the sub-factors of the health promotion behavior in this research was as Table 1.

Table 1. Sub-factor Reliability of HPB Measurement Tool

2.2.2. Emotional happiness

Emotional happiness was measured by the positive and negative affect scale (PANAS) developed by Watson. D., Clark. A. A., & Telangana. A. [15]. This questionnaire was a 5-point Likerts composed of 10 items related to positive emotion and 10 items representing negative emotion. Negative emotions were calculated by scoring backwards. And the higher the score, the higher the emotional happiness. In this research, the reliability (Cronbach alpha) of PANAS was 0.904.

2.3. Research participants

Participants who participated in the research were 20-30 generations in Korea who voluntary responded by sending the questionnaire online at random. Among the respondents who participated in the study, 279 copies of the data were used for the analysis. The survey period was December 1 to 15, 2018.

4. Conclusion

The beginning of this research began with the report the happiness index of 20-30 generations in Korea was low. A total of 279 participants were included in this research and those who voluntarily participated by sending a questionnaire online. Data collection for the study was conducted from December 1, 2018 to December 15. The questionnaire for the study consisted of general characteristics, health promotion behavior items, and emotional happiness items. The time required the questionnaire response was about 10 minutes. Analysis methods for this research were frequency analysis, t-test, ANOVA, and multiple regression analysis using SPS 18.0. As a result of general characteristics analysis, there were 36-39 years old with 198 (71.1%) of them, in the following case, 48 (17.2%) were below 25 years old, 21 (7.5%) were 31-35 years old and 14 (4.3%) were 26-30 years old. The participants of this research were limited to 20-30, but most of the respondents actually took over a relatively large proportion of the 36-39 year olds and needed an understanding of the interpretation of the original research purpose. And also among the participants 198 (71.0%) were males and 81 (29.0%) were females. In other words, the majority of this study could be attributed to males aged 36-39. Of the respondents, 125 (80.7%) were drinking alcohol and 69 (24.7%) were the most likely to drink for social relationship making, 32 (15.1%) were drinking alcohol because they just liked alcohol, 3 (1.8%) were drinking alcohol because of their mod, 30 (21.5%) drink alcohol to relieve stress. Of the respondents, 125(80.7%) responded that hey drank alcohol. Of these, 62 (49.6%) were drinking alcohol for socialization and stress relief. These results indicate that almost half of the respondents have solved interpersonal problems and stress by drinking alcohol. And the number of people eating twice a day was the highest with 129 (46.2%) people, with 123 (4.1%) with 3 people and 21 (7.5%) people with irregular, once a day meal per day was 3 (2.2%). And 129 (46.2%) of those who eat two meals a day were found not o eat nutritionally balanced meals. As a result of the correlation analysis between health promotion behavior and emotional happiness, there were strong correlations between two of them in the statistical significance level (p<0.01). The results of this study were similar to those of a reported by Scorcolini-Comin F et al., through ‘The scientific study of happiness and health promotion: an integrative literature review [16]. These above results showed that the sub-factor of health promotion behaviors affect emotional happiness. As a result of the effects of health promotion behaviors’ sub-factor on emotional happiness, personal hygiene (t=2.627, p<0.05), substance abuse (t=-2.524, p<0.05), social relation formation (t=7.417, p<0.01), self-actualization (t=6.098, p<0.01) factors were found to affect to emotional happiness at statistical significance. Results such as these were similar to those highlighted in cross-cultural review and [17-18] and it was similar to what Diener E emphasizes in its analysis of subjective well-being. In other words, among the five sub-factor of health promoting behavior, fur domains except nutrition were found to affect emotional happiness. Based on the above results, it was suggested that the program of happiness for living in the 20-30s age groups should strengthen the contents of health responsibility, guidance of substance abuse, formation of social relations and self actualization.
