This study aims to identify the relationship between stress and feeling of happiness among high school students, and to examine the double mediating model of subjective well-being and gratitude disposition on that relationship. Participants of this study were 245 male and female high school students. Perceived Stress Scale, Satisfaction with Life Scale, Emotion Frequency Test, Gratitude Questionnaire-6, and Subjective Happiness Scale were used for this study. To analyse a sequential double mediating effect, PROCESS Macro 3.5 Model 6 was used. Results revealed that stress was negatively correlated with subjective well-being, gratitude disposition, and feeling of happiness among high school students. And, subjective well-being was positively correlated with gratitude disposition and feeling of happiness, while gratitude disposition was positively correlated with feeling of happiness. It was found that subjective well-being and gratitude disposition were sequentially mediating stress and feeling of happiness among high school students. Because these findings suggest that subjective well-being and gratitude disposition play important roles in adolescents' happiness, it is necessary to promote their subjective well-being and gratitude disposition.

Objectives : The purpose of this study was to develop the Korean Strength Scale and to examine its validity and reliability. Methods : The Korean Strength Scale is a self-report questionnaire that measures 25 valued strengths and is comprised of 124 items ; each item had a 0-5 rating on a 6-point scale. In order to test validity and reliability, data were collected from 355 adults. The measures included the Korean Strength Scale, HEXACO Personality Inventory (HEXACO-PI), Satisfaction with life scale (SWLS), Positive Affect and Negative Affect Schedule (PANAS), and Orientations to Happiness Questionnaire (OHQ). Results : The resulting exploratory factor analysis of the Korean Strength Scale suggested 4 factor structures. The Korean Strength Scale was shown to have acceptable psychometric properties, including acceptable internal-consistency reliabilities, factorial validity, and high convergent correlations. Conclusion : Although there is room on improvement for some facet scales, the Korean Strength Scale appears to be a useful tool for assessing an individual's signature strengths.

현대의 시스템들이 가지는 고기능화와 자동화로 인하여 인간의 운용 능력이 점점 더 중요한 능력으로 부각되고 있으며, 이는 사용자가 경험하게 되는 인지넉 복잡도를 제어하는 것을 요구한다. 본 연구에서는 사용자 인터페이스에서 사용자가 경험해야 하는 인지적 복잡도를 스키마 구조를 반영하여 정량화하는 엔트로피 모형(윤완철, 1992)을 적용하여 사용자가 겪게 될 인지적 복잡도를 예측하는 척도가 제안되었으며 실험적으로 검증되었다. 엔트로피와 시스템 크기-조작의 수와 상태의 수-가 각각 다른 세 가지 인터페이스 (엔트로피가 낮고 작은 크기의 인터페이스, 엔트로피가 높고 작은 크기의 인터페이스, 엔트로피가 높고 큰 크기의 인티페이스) 중의 하나를 사용하는 것을 피험자이 학습하고, 이에 대해 검사를 받았다. 제안된 척도인 시스템 엔트로피는 사용자 수행도를 잘 설명하였지만, 시스템의 크기는 그러하지 않았다. 본 연구는 사용자가 겪게 될 인지적 복잡도를 평가자의 주관이 개입하지 않는 방법을 통하여 평가할 수 있음을 보인 것으로 가전제품이나 스프트웨어의 디자인의 평가와 개선 등 인간의 인지적 복잡도가 사용성에 중요한 영향을 미치는 분야에서 유용하리라 여겨진다.

Self-directed learning ability is more important than before. It is well-known that traditional teacher-directed lecture class, seminar-like oral presentation class, and even discussion/debate class have not been enough to enforce self-directed learning ability for students. To resolve the problem, a new dynamic complex instruction model (DCIM) was developed for undergraduate and graduate students and a basic frame of DCIM was published by Oh (2010). Here, it is examined if the application of DCIM to a biology class of graduate school can cause improvement of self-directed learning ability. For this, the self-directed learning readiness scale (West & Bentley, 1990) translated by Ryu (1997) and motivation scale (Hayamizu. 1997) translated by Oh (2001) were employed, and then measurements performed with the translated scales were done in the beginning and the last of two DCIM-adapted graduate biology classes at K university, Daegu, South Korea in the first semester of the year 2010. The results show that self-directed learning ability could be significantly improved through the DCIM-adapted class, compared to the result of a teacher-directed lecture class as a control group. With respect to the motivation, there was not found any statistically significant difference between control and experiment groups of graduate students. The present study seems to be meaningful in that it is the first work proving the effect of improvement of self-directed learning ability of graduate students through the DCIM-adapted classes.

The purpose of this study was to examine the validity and reliability of the Playfulness Scale for Adults. The Korean version of the Playfulness Scale for adults was developed by Proyer, R.T (2017) to measure the playfulness of adults. To validate the OLIW in Korean, item translation, back-translation, item analysis, and exploratory factor analysis (EFA) were conducted with 406 adults in study 1. Of the results obtained from study1, three items and one factor (7 items) were discarded because they turned out to be improper. In addition, 4 factors that were not the same as the original scale were extracted. This was checked by conducting confirmatory factor analysis (CFA) with 336 adults in study 2. CFA supported the 4 factors structure and all 4 factors showed adequate internal consistency. To check the concurrent validity of the Korean adults playfulness scale, correlation analysis with the APS, SMAP, PSYA, and NEO Personality Assessment was conducted. It showed significant positive correlation to APS, SMAP, PSYA, and showed the similar patterns of correlation with the sub factors of NEO Personality Assessment. Adult playfulness is related to the participation frequency of leisure. In conclusion, the Korean version of the playfulness scale for adults is a valid measure of playfulness for adults in Korea. The implications, practical use and suggestions for future study were discussed.

This study developed 'Design Career Aptitude Scale' to help design majoring college students who are seeking their career goals or conflicting to decide their majors. The subscales of the 'Design Career Aptitude Scale' are 'basic job competency', 'basic design competency' and' advanced design competency'. This study further classified the 'basic job competency' and 'basic design competency' into several subareas and defined each concepts. Based upon the classification of each subareas, tentative test items were developed through the verification of validity three times by seven design professionals. A pilot study of the developed scale was administered to 506 design majoring college students. The results by exploratory factor analysis were that the basic job competency was composed of four factors; ability of interpersonal relations, goal-driven ability, problem solving ability and self-developing ability. The basic design competency was composed of five factor, grounding in design, computer skills, material sensitivity, formative ability and color sensitivity. The results can be seen as an adequate, delicate factor structure to represent design aptitude, and also the scale can be a useful tool to the students who are conflicting to decide their majors and careers. The further study needed to validate the scale through the investigation of the relationship with related scales measuring designing ability, and with other criteria-referenced group.
