The objective of the research is to investigate the causal relationships among functional value, emotional value, social value, perceived sacrifice, satisfaction, loyalty and behavioral intention. All in all, 296 respondents completed a questionnaire themselves in the presence of an interviewer who could be consulted about the response scales and other technical matters. Behavioral intention models were estimated by structural equation modelling using 7 latent constructs. The results demonstrated that the confirmatory factor analysis model provided a good model fit. The unconstrained model yielded a significantly better fit to the data than the constraint model. The effects of functional value and social value on satisfaction and behavioral intention were statistically significant. The effects of perceived sacrifice, satisfaction and loyalty on behavioral intention were statistically significant. As expected, satisfaction had a significant effect on loyalty. Functional value had an indirect effect on behavioral intention through satisfaction and loyalty. Moreover, social value had an indirect effect on behavioral intention through satisfaction and loyalty. Replicating and extending this study in other regions and other samples would test the generalizability of the present findings and provide a basis for an external validation of the framework developed in this paper.

The purpose of this study was to identify the influencing factors on the compliance of breast self-examination (BSE) among 205 Christian women living in Pusan and U1san areas. Structured self-administered questionnaires were used. Knowledge levels were measured by the instrument developed by Choi(l996). Self- efficacy and health belief were measured by the instruments developed by Champion (1993) and modified by Choi(1996). Women who did BSE more than once within 6 months were categorised as compliant. Data was analyzed by descriptive statistics, t- test, χ² test and logistic regression analysis using SPSS WIN program. The results of this study were summarized as follows； 1. 15.1％ of women performed the BSE at least once during the last 6 months. 2. Non-complier and compliant women showed statistically significant differences in the level of self efficacy and barriers. 3. Predictors of BSE compliance were ‘history of having breast disease’, ‘experience of receiving recommendation for BSE’, ‘barriers’, and ‘experience of meeting with breast cancer patients’ and explained 14.8％ of variance in compliance of BSE. For future clinical practice, health professionals, including nurses, need to actively suggest to women the importance of BSE, and to distribute the information through posters and pamphlets at clinics and public health centers. Including the opportunity to meet patients in health education centers can be another strategy to increase women's motivation for BSE. For future research, it is necessary to recruit women from broader geographic areas utilizing various sources such as community centers to increase generalizability of the findings.

The globalization of Korean food has long been an important agenda for both the Korean government and food-related firms, and there have been many trials and errors because of cultural differences in food consumption habits. This study explores Chinese consumers' purchase behaviors toward chicken menus, and for a better understanding of these behaviors, the study considers differences in consumer behavior in between Chinese and Korean consumers around Daejeon, South Korea. The sample included a total of 232 respondents who provided information on their purchase behaviors toward chicken menus. A total of 13 purchasing attributes were compared through a t-test, and according to the results, there were significant differences in 6 attributes: "like the taste" (p<0.001), "as a side dish for drinks" (p<0.001), "to feel good" (p<0.01), "like all chicken dishes" (p<0.05), "for health" (p<0.05), and "low prices" (p<0.05). The results for chicken consumption indicate significant differences in frequency (p<0.05), goals (p<0.01), and expected fair prices (p<0.05). These results suggest that, to make Korean chicken dishes a global Korean menu, future research should focus on consumers' motives for purchasing chicken menus, satisfaction, and characteristics. The generalizability of the results may be limited because the survey was conducted by considering only those students in the Daejeon area. Future research should include a wider range of consumers in both Korea and China for better strategic plans for food-related firms.

This study examined intakes of nutrients, carotenoids and polyphenols according to lens turbidity levels among adults visiting a cataract clinic. A total of 102 males and females aged 40 years or higher agreed to participate in the study, and a face-to-face survey interview was conducted to obtain information on general characteristics, health behaviors, and dietary intakes of each participant. The dietary data were collected by a food frequency questionnaire which was previously validated in a Korean population. In addition to essential nutrients, intakes of a total of 10 carotenoids and polyphenols were calculated based on the tables of food functional composition developed by National Academy of Agricultural Science. The subjects were divided into 3 groups according to turbidity levels (< 16, ${\geq}16$ and < 25, ${\leq}25$), and health behaviors and dietary intakes were compared among the turbidity groups. Data showed seemingly higher energy intake and lower dietary antioxidant (i.e., vitamin A, ${\beta}$-carotene, lutein, zeazanthin, lycopene, cryptozanthin) intakes in the highest turbidity group. However, no statistically significant findings were found in all the comparative analysis on characteristics of health behavior and intakes of nutrients, carotenoids and polyphenols. The current study findings should be cautiously interpreted in consideration of several limitations including a cross-sectional study design, a small sample size, uneven sample size distribution across turbidity groups, and limited generalizability due to using a convenience sample. Therefore we cannot conclude that the risk of cataract is unrelated with dietary antioxidant intakes based solely on the results of this study.

Since 1998 when economic assistance from IMF started, the empirical research on the effects of unemployment and drastic income loss on psychological functioning among the unemployed as well as their family members has increased. These studies have found that unemployment and drastic income loss following unemployment have significant negative influence on the psychological outcomes such as anxiety and depression of the unemployed and their family members. Studies have also focused on the role of social support in this process, and reported that depending on the levels of received social support, unemployment and income loss have differential effects on the psychological aspects of the unemployed. However, these studies have several weaknesses. First, most of the related studies employed the data which were collected from limited regions of the country, which imposes limitations on the scope of the generalizability of research findings. Second, the main independent variables used in these studies were mainly unemployment or income loss, which ignore the psychological evaluation by the employed of their family financial situations. Third, in analyzing the moderating effects of social support, most studies have focused mainly on showing the existence of moderating effects by social support. Consequently, the nature and role of social support remained unanalyzed and left to speculations. The purpose, of this study is to examine the effects of economic pressure experienced by family heads who were unemployed and to analyze the moderating role of social support based on a nationally representative sample. The findings showed that economic pressure has negative influence on anxiety and depressive feelings among the unemployed, and that the effect of economic pressure on depressive feelings were substantially higher among those who have received lower levels of social support from family members than that among those with higher levels of family support.

Students must be familiar with clinical skills before starting clinical practice to ensure patients' safety and enable efficient learning. However, performance is mainly tested in the third or fourth years of medical school, and studies using the validity framework have not been reported in Korea. We analyzed the validity of a performance test conducted among second-year students classified into content, response process, internal structure, relationships with other variables, and consequences according to Messick's framework. As results of the analysis, content validity was secured by developing cases according to a pre-determined blueprint. The quality of the response process was controlled by training and calibrating raters. The internal structure showed that (1) reliability by generalizability theory was acceptable (coefficients of 0.724 and 0.786, respectively, for day 1 and day 2), and (2) the relevant domains had proper correlations, while the clinical performance examination (CPX) and objective structured clinical examination (OSCE) showed weaker relationships. OSCE/CPX scores were correlated with other variables, especially grade point average and oral structured exam scores. The consequences of this assessment were (1) making students learn clinical skills and study themselves, while causing too much stress for students due to lack of motivation; (2) reminding educators of the need to apply practical teaching methods and to give feedback on the test results; and (3) providing an opportunity for faculty to consider developing support programs. It is necessary to develop the blueprint more precisely according to students' level and to verify the validity of the response process with statistical methods.

Objectives: This was to examine and explore the elements of Size Korea 6th 3D head anthropometric database and to provide basic information for the selection of respirators in Korea. Methods: This was a pilot study for the first year of work in a two-year-project initiated at KOSHA in 2021. 3D head dimensions data were obtained from the Size Korea Center managing the Size Korea 6th 3D national anthropometry survey databases. The 3D head dimensions data, including 45 dimensions, were used in line with ISO standards (e.g., ISO/TS 16976-2) for examinations, comparisons, statistical analyses, etc. Results: A total of 3,088 subjects were finally determined in this study. The main features were: Male subjects were 52.5%; the highest age group was 15-29 at 36.7%; unhealthy weight group based on BMI was 31.7%; and survey area was the capital region. For the 6th 3D head dimensions data with 45 items, the means and standard deviations for 'Face length' were 115.9±7.5 cm for males and 107.3±6.9 cm for females respectively while those for 'Face width' item were not available since there was no such item in the data. Numerous findings were discussed accordingly. Conclusions: This study showed that there were likely requirements for improvements in the 6th 3D head anthropometric data as follows: Standardization of Korean and English terms; addition of head dimensions items missed in the Size Korea survey; and reliability of generalizability for subjects, suggesting that the study results can be used for further studies or improvement of respirator selection in Korea.

The purpose of this case study is to investigate an empirical analysis on how public opinion spreads, when is the effect to occur, and how much effective. Data from the 19th presidential election period, specifically supporting rates for a candidate, Moon Jae-in were used. Results indicated that a supporting rate of increase were not linear and the points where the rate of increase is enhancing was 27-8%. It was 1.4 times higher than the previous period. Results providing this research is not appropriate for generalizability due to a characteristic of a case study, but this study has a value in trying to statistically analyze the accurate figures for how much 'majority opinion' is.

Using strategy group theory, this thesis reviewed the status of program providers analysis and the performances it has made so far, and sought measures to improve its limitations. The constraint of program providers analysis based on existing concept of strategy group is that the strategy group was derived from the statistics, and therefore only applied the characteristics of program provider's channels to the analysis, on account of which a systematic and sophisticated classification as well as generalization of strategy or strategy group were hard to obtain. Moreover, the PP strategy variables used to be selected at the firm level and business level, and in relation with resource and competition scope. In future, more appropriate procedure should be followed to obtain objectivity in selecting variables to avoid controversy over intentionality. The measures in this thesis to improve the study of PP strategy group can be summarized as follows: firstly analysis of variables for strategy group classification should be made to single out key variables which are to be classification criteria. Secondly, variables are to be cross-checked by industry experts to increase generalizability. Thirdly, proxy variables should be sublated, and strategy group model which enables the reflection of subsistent properties of PP industry, and the cognitive perception of the executives(CEO) needs to be established. Fourthly, the concepts of mobility barrier and isolating mechanism should be applied to the classification criteria of strategy group to reveal the gap of performance between different strategy groups. Lastly, chronicle study on PP strategy group should be done to perceive the dynamic changes of PP strategy group.

The purpose of the present study is to develop and validate an instrument to assess STEM career motivation. We developed 32 items for 7 constructs (i.e. education experience, career value, academic self-efficacy, career self-efficacy, career interest, parents' support, and career motivation) on STEM career motivation based on Social Cognitive Career Theory (SCCT; Lent et al.,1994). 767 first year high school students participated in this study. The items were validated by Messick's framework (1995). In this study, we examined the validity of items in four aspects (i.e. content, substantive, structural and generalizability of validity). Methodologically, we used Rasch analysis, Exploratory factor analysis, confirmative factor analysis based on structural equation modelling. We confirmed that our instrument with 32 items as valid and reliable for measuring the STEM career motivation. In addition, we tested the STEM career motivation model based on SCCT. Our model explained the data well, suggesting that external factors (education experience and parents' support) and cognitive factors (perception of value, self-efficacy and interest) were significantly related to STEM career motivation.
