  • Objective : This study aimed to develop and preliminary validate the Mibyeong Questionnaire (MQ) based on Deficiency-Stagnation pattern, which was report of a person's health condition that comes directly from the person. Method : The first phage of developing a MQ was to generate and exhaustive list of all MQ issue that are relevant to the domain of interest, using literature research and expert group discussions. Through those steps, we established MQ with 33 items divided into two parts: 21-item deficiency pattern and 12-item stagnation pattern. The second phage, we examined the preliminary tests of reliability and validity including the 16-item Deficiency of MQ (16D-MQ), with data (n=1,890) already collected on the Korean medicine data center in KIOM. Results : Exploratory factor analysis revealed three factors of the 16D-MQ. These factors were fatigue(Qi, 氣); psychic and physical elements(Shen, 神); and skin and hair(Jing, 精). Cronbach's coefficient alpha was 0.876 and the intraclass correlation coefficients was 0.368-0.538. In support of criteria validity, the 16D-MQ was weakly correlated with EQ-5D and physicians's opinion, but it was acceptable. Conclusion : The MQ shows that it has an appropriate level of internal consistency and validity. We think further study to reveal its reliability and validity, including stagnation pattern as well as deficiency pattern, is needed.

  • 문제해결력 및 창의력 등과 같은 고등정신능력 배양을 위한 평가체제 구축의 일환으로 2005년 도입된 서술형 평가는 매년 평가비율이 증가하면서 단순 지식을 요구하는 선다형 평가의 대안적 평가로 떠오르고 있다. 정부의 서술형 평가 비율 확대로 학교현장에서 표면적으로는 어느 정도 정착이 되어 운영되고 있으나 실제 서술형 평가가 의도한 목적을 달성했다고 확언할 수 없다. 그래서 본 연구에서는 경기도 5개 중학교에서 실시된 과학과 서술형 평가 문항을 대상으로 서술형 평가 문항의 특성을 분석하였으며, 이러한 특성을 갖는 요인을 분석하고자 문항을 출제한 교사를 대상으로 심층면접을 실시하였다. 연구결과 서술형 평가 문항들은 ① 출제되는 단원의 편중, ② 단원별 문제 형식의 차이, ③ ‘고등정신능력’ 측정의 미흡이라는 문항의 특성을 갖고 있었다. 이러한 문항의 특성을 갖는 요인은 교사들의 평가 문항 제작, 평가 도구의 이해 등에 대한 능력이 결여되었기 때문이었다. 이러한 요소들은 모두 평가 전문성의 결여로 설명될 수 있다. 이를 통해 교사들의 평가 전문성을 신장을 위한 방안이 요구됨을 알 수 있었다.

  • The purpose of this study is to develop and validate a maternal happiness scale which can be used for mothers who take care of young children, school-aged children, and adolescents. First, the maternal happiness scale was developed based on literature review and the consent of experts. Finally it was consisted of 56 items from 18 elements of happiness through checking the contents validity with professionals. Second, final respondents for the survey were 1300 mothers who had children with and without disabilities in Seoul, Busan, Gyeonggi, and Kyungnam. Third, the 8 factors including the 53 items were extracted through the mothers' appraisal of the items and the review of the adequacy for the factor analysis. The 8 factors were consisted with 'Family relations with family', 'Laid-back life and self-esteem', 'Physical and mental health', 'Independency and development', 'Spirituality', 'Interpersonal relations', 'Appearance', 'Sociocultual environment'. Fourth, the maternal happiness scale demonstrated appropriate levels of construct validity, item internal consistency, distribution of item response, and item discrimination. The results of this study enhance our understanding of the core factors of maternal happiness. In addition, the findings have implications for supporting mothers who take care of young children, school-aged children, and adolescents.

  • Purpose: This paper was conducted to validate the Korean version of the Peer Group Caring Interaction Scale (PGCIS-K) that measures caring behaviors as experienced by nursing students. Methods: Translation of the PGCIS-K was validated through forward-backward translation methods. Survey data were collected from 218 nursing students in a nursing school. Construct validity and criterion-related validity were evaluated. Internal consistency and the Guttman split-half coefficient were calculated to assess reliability. Results: The PGIS-K showed reliability except for 4 items (Cronbach's ${\alpha}=.91$, Guttman split-half coefficient=.85), which were low (<.30) or negatively correlated with the total scale. A 12-item reduced form of the PGCIS-K was developed by item-analysis and construct validity evidence. Factor loading for the 12 items on 2 factors ranged from .47~.82, which explained 58.4% of the total variance. Two factors were named 'modeling and assistance (Cronbach's ${\alpha}=.87$)' and 'communication and sharing (Cronbach's ${\alpha}=.82$)'. Convergent validity, discriminant validity, and criterion validity were supported according to the correlation coefficients of the 2 factors with other measure. Conclusion: The findings suggest preliminary evidence that the 12-item PGCIS-K can be used to measure nursing students' peer group caring interactions in Korea. Additional studies are recommended to continue the psychometric evaluation of this scale. Also, it can be extended to measure graduate nursing students or staff nurses' peer group caring interaction.

  • This exploratory research explores the concept of a digital legacy as a general concept and as a collection of digital possessions with unique characteristics. The results reported in this article are part of a larger study. In Cushing (2013), the author identified the characteristics of a digital possession. In this study, these characteristics of a digital possession were utilized to explore how the characteristics of several digital possessions could form a collection, or a digital legacy. In addition to being explored as a collection of digital possessions, data was collected about the general concept of a digital legacy. In part I of the study, 23 participants from three age groups were interviewed about their general concept of a digital legacy. Five general characteristics describing a digital legacy were identified. In part II of the study, interview data from Cushing (2013) was used to create statements describing digital possessions. The statements were classified utilizing the archival concept of primary and secondary values, as well as the consumer behavior concepts of self extension to possessions and possession attachment. Primary value refers to the purpose for which the item was created, while secondary value refers to an additional value that the participants can perceive the item to hold, such as a perception that an item can represent one's identity. Using standard Q method procedure, 48 participants were directed to rank their agreement with 60 statements (written on cards), along a distribution of -5 to +5, according to the characteristics of the digital possession they would most like to maintain for a digital legacy. The ranked statements were analyzed using Q factor analysis, in order to perceive the most common statements associated with maintaining digital possessions for a digital legacy. Q method results suggested that most individuals described the digital possessions they wanted to maintain for a digital legacy using various combinations of characteristics associated with primary and secondary values. This suggests that while some participants will respond to personal archiving based on the concept of preserving identity (a perceived secondary value), this will not appeal to everyone. Information professional could consider this difference in appeal when marketing personal archiving assistance to patrons.

  • This study was attempted to grasp the push-pull factors of urban to rural migrants in relation to services and infrastructure of rural welfare and culture. Online and offline survey were conducted for urban residents who were willing to return to the rural area and those who were already returning to the rural area. In the fields of health care, social welfare, and education, it was found that the satisfaction level of urban-to-rural migrants was relatively higher than those of latent urban-to-rural migrants. In the field of culture, leisure and sports, the level of satisfaction and concern were similar, so it was found that the expectations for the field were relatively high before returning rural area. As for the agreement degree to expand support, the demand for emergency medical facilities and dementia care program was the highest, and the demand for health care was found to be relatively high. The results of the survey on the top priority items indicate that latent urban-to-rural migrants require support of facility and space item and expansion of program item, and urban-to-rural migrants have high demand for expansion of program item in all field except healthcare field. The results of this study are expected to provide useful information for establishing the direction of the rural area development project in connection with the revitalization of policy of people return to rural area.

  • The purpose of this study was to define the purchase behavior of online luxury fashion brand consumers that soon became new luxury consumption trends. To investigate online luxury fashion brand consumer's purchase behavior, three variables were suggested based on advanced researches. These variables include economic value, item variety and pleasure. Purchasing luxury online was not common but as cross-border online shopping market became popular, consumers began to purchase luxury items through online shopping platforms. Preliminary surveys was conducted on 20~40-year-old consumers who have experience in online shopping for luxurious items. Total 238 questionnaires were used for analysis. By using SPSS, frequency analysis, factor analysis, reliability analysis, correlation analysis, regression analysis, t-test and ANOVA were conducted. The results of the study were as follow; first, consumer's purchase behavior appeared to be influenced by the order of pleasure of shopping, economic value and item variety. Repurchase intention appeared to be affected by the order of economic value, item variety, and pleasure of shopping. Second, online luxury fashion consumers perceived that risk does not affect purchase intention and repurchase intention. Third, as purchase intention increases, repurchase intention also increases. Fourth, shopping value, age and channel risk also indicated meaningful differences. As an early study of luxury fashion brand products purchased directly online, the academic significance can facilitate an overall understanding of consumer behavior such as usage motive, risk perception, behavioral intention.
