Purpose: This study aimed to valuate the reliability and validity of the Korean version of the 5C Psychological Antecedents of Vaccination (K-5C) scale. Methods: The English version of the 5C scale was translated into Korean, following the World Health Organization guidelines. Data were collected from 316 community-dwelling adults. Content validity was evaluated using the content validity index, while construct validity was evaluated through confirmatory factor analysis. Convergent validity was examined by assessing the correlation with vaccination attitude, and concurrent validity was evaluated by examining the association with coronavirus disease 2019 (COVID-19) vaccination status. Internal consistency and test-retest reliability were also evaluated. Results: Content validity results indicated an item-level content validity index ranging from .83 to 1, and scale-level content validity index, averaging method was .95. Confirmatory factor analysis supported the fit of the measurement model, comprising a five-factor structure with a 15-item questionnaire (RMSEA = .05, SRMR = .05, CFI = .97, TLI = .96). Convergent validity was acceptable with a significant correlation between each sub-scale of the 5C scale and vaccination attitude. In concurrent validity evaluation, confidence, constraints, and collective responsibility of the 5C scale were significant independent predictors of the current COVID-19 vaccination status. Cronbach's alpha for each subscale ranged from .78 to .88, and the intraclass correlation coefficient for each subscale ranged from .67 to .89. Conclusion: The Korean version of the 5C scale is a valid and reliable tool to assess the psychological antecedents of vaccination among Korean adults.

The Body Appreciation Scale-2 (BAS-2) measures the extent to which individuals feel, accept, and respond to their own bodies in a positive manner. Given the research need to explore positive body image and its associations with various sociocultural factors and related consequences among individuals with various cultural backgrounds, several studies have established the psychometric properties and factor structures of the BAS-2 in different languages and samples with different characteristics. The current study investigated the psychometric properties and measurement invariance of a Korean version of the BAS-2 in an older Korean adult population (599 older Korean adults with the average age of 70 years). Data were collected using both online and offline (paper-based) survey questionnaires. The results of exploratory factor analyses and confirmatory factor analysis evidenced the unidimensional factor structure and measurement invariance of the Korean BAS-2 among older Korean men and women, after dropping item 1. Scalar invariance was supported across gender, and men and women did not significantly differ in observed mean scores of the Korean BAS-2. The results also supported good convergent validity and criterion validity. Incremental validity was demonstrated by predicting self-esteem over and above measures of age, BMI, subjective financial and health status, body esteem, and ageism. High internal reliability and test-retest reliability over a 2-week period were confirmed. Overall, the results of this study support the reliable use of a Korean BAS-2 to measure positive body image among older Koreans after excluding item 1.

This study was conducted to design long and short forms of reliable and valid Likert-type scales to measure environmental attitudes of Korean junior high school students. 8 tests were applied to the construction of a 32-item long form and 8-item short form of the scale. Two scales were field tested on 469 respondents consisting of male and female students in urban and rural areas and students participating in environmental programs. The 32-item scale was revealed to be highly reliable, content and construct valid. Reliability and homogeneity of this scale were evidenced by 0.92 coefficient alpha and positive interitem correlation values ranging from 0.10 to 0.52. Factor analysis and known-group comparison showed the sufficient validity of long form scale. Reliability and validity of short form scale were also evidenced by good results of 8 test analyses. The long and short forms were strongly correlated, ${\gamma}$-value of 0.90. Consequently, both long form and short form scales were evidenced very reliable and valid in measuring environmental attitudes of junior high school students in Korea. They can be useful for a variety of survey conditions and constraints and testing environmental attitude.

The purpose of the study was to examine the characteristics of the Kansas Marital Satisfaction Scale(KMSS). KMSS was designed as a short and direct assessment of marital satisfaction. The scale consists of three items where respondents are directly asked how satisfied they are with their marriage, with their partner as a spouse, and with their relationship with their spouse. 1) Through item analysis, three items were significant discrimination for husbands and wives. 2) The KMSS consisted of 1 factor for husbands and wives. 3) Cronbach alpha estimates of internal consistency reliability of 93 for husband and of 89 for wives. 4) For wives, the item means between satifaction with their marriage and satisfaction with their relationsphip with their husbands were significantly different, even though the items were highly correlated. For husbands, three item means weren't significantly different. 5) The distribution of responses to the scale for husbands and wives departed si nificantly from normality in terms of skewness and kurtosis. 6) The scale was correlated, in expected directions, with the Marital Comparison Level Index (MCLI) and Marital Instability Index(MII), for husbands and wives. In conclusion, the scale offers promise for use in clinical evaluation and survey research where a brief but reliable measure of marital satisfaction is required.

The modem industry age began when the conveyer system was introduced by Ford to produce model "T". The conveyer system is designed to optimize and maximize mass production of a specific item. Nowadays, however, accommodating to individual tastes has become an important factor in selection of products. Thus, rather than the mass production of one item, producing fewer but a wide variety of goods became important. To give flexibility and elasticity to the conveyer system, a new method of transportation where it is possible to choose a specific item is necessary. Therefore mall quantity and high-volume mass production was decrescent and small quantity batch production was expanded. In this paper, we developed multiple crate stacking and picking system to give flexibility to the conveyer system. First, we verified the conceptually designed system through manufacture. Second, we solved the problems that would happen on the actual field using pneumatic system. Finally, we optimized the system through FEM technique. This system works with stability and fast speed and can improve work efficiency which would minimize the losses resulting from too much dependence on manual labor.

This study is intended to create a tool which can identify the concept of consumption life level and to develop a standardized scale to measure consumption life level. Based on it, the concept and perspective of consumption life level was formed and then the scale for measuring it was developed. To develop the scale, the scale was firstly formed by extracting questions through a literature survey, and verifying validity through experts' opinions. Then the final scale was developed by conducting a questionnaire survey for consumers. A preliminary 27-item scale was developed through a literature review. 1000 consumers responded to an online survey using the preliminary scale. This research was made with the intention of not only supplying academic data on the consumer's consumption life level but also understanding the consumer's basic behavior patterns. Then a series of tests: test-retest, item-to-total correlation, and Cronbach's reliability coefficient and factor analysis were conducted using the survey data and the final 20-item scale was constructed in the end. The consumer's consumption life level scale consisted of 4 factors.

This study was conducted to examine the effects of local food value perception on purchasing and experience in consumers. ${\chi}^2$-test, ANOVA, and linear regression analysis were conducted. The findings are summarized as follows: The most common place for buying agricultural products was 'hypermarkets' (41.7%), and the most important factor for purchasing local food was 'local government's certification products' (23.7%). The most important value recognition item for local food was 'I think that local food is a high-quality agricultural products'. (3.74 points), followed by 'I think that local food have a value of respect for customers' (3.61 points) and 'I have a faith for the local food'. (3.61 points) in that order. The main tourism experience activity was 'food experience' (49.0%), and information source of local food experience tourism was 'mass media (TV, newspapers, etc.)' (37.3%). As age increased, experience of local food also increased. The most effectual value recognition item for purchasing local food was 'I think that local food have a value of respect for customers'. The most effectual value recognition item for increasing intake experience of local food was 'I think that the local food is high-quality agricultural products'.

본 연구는 언어 네트워크 분석을 활용하여 기능성 아이템과 장식용 아이템, 두 집단 간의 아이템 중요도 및 과금에 대한 생각을 연구하였다. 분석 결과로는 기능성 아이템을 구매하는 유저는 유료 아이템을 구매할 때 경쟁에 영향을 줄 수 있는 전투력과 능력치 요소가 함유된 유료 아이템의 영향을 많이 받는 것으로 나타났다. 이에 반해 장식용 아이템을 구매하는 유저는 자기만족감을 최우선으로 여기며, 캐릭터의 외형 변화를 통한 치장과 이러한 치장용 아이템 수집욕을 중시하는 것으로 나타났다. 또한 이들은 결과에 영향을 미치지 않는 아이템 구매를 통해 게임의 재미를 느끼고 있었으며, 나아가 게임 캐릭터를 통해 자기 자신의 투영과 '또 다른 나'를 인식했다,
