  • This study examined affective representation by analyzing physiological responses measured using wearable devices and affective ratings in response to emotional videos. To achieve this aim, a published dataset was reanalyzed using multidimensional scaling to demonstrate affective representation in two dimensions. Cross-participant classification was also conducted to identify the consistency of emotional responses across participants. The accuracy and misclassification in each emotional condition were described by exploring the confusion matrix derived from the classification analysis. Multidimensional scaling revealed that the represented objects, namely, emotional videos, were positioned along the rated valence and arousal vectors, supporting the core affect theory (Russell, 1980). Vector fittings of physiological responses also showed the associations between heart rate acceleration and low arousal, increased heart rate variability and negative and high arousal, and increased electrodermal activity and negative and low arousal. Using the data of behavioral and physiological responses across participants, the classification results revealed that emotional videos were more accurately classified than the chance level of classification. The confusion matrix showed that awe, enthusiasm, and liking, which were categorized as positive, low arousal emotions in this study, were less accurately classified than the other emotions and were misclassified for each other. Through multivariate analyses, this study confirms the core affect theory using physiological responses measured through wearable devices and affective ratings in response to emotional videos.

  • The purpose of this study is to summarize study trend and achievements of recreation specialization, introduced to Korea in 1996 and recently started to be discussed a lot, and to state the problems and future development. Data related to recreation specialization were collected by using the database of KISS and RISS and 34 studies were utilized for the analysis. The studies were classified into six types; type I-introduction and proposal, type T-study tendency of recreation specialization in foreign countries, type U-quantitative studies using uni-dimensional approach to recreation specialization, type M-quantitative studies using multi-dimensional approach to recreation specialization, type Q-qualitative studies, and type S-variable relations using SEM. One of the problems found in the studies is that recreation specialization is still analyzed by using uni-dimensional approach to recreation specialization. Second, measures directly translated from foreign studies need to be verified the validity. In addition, domestic studies tend to simply follow foreign studies. Lastly, the studies lack variety(diversity) of research methods and researchers. The authors of this study argue that researchers must develop measures appropriate to Korean culture and diversify the research subjects and study methods.

  • The purpose of this study was to look how workaholism regulates the effect on the relation between the perfectionism types - self-oriented perfectionism (SOP), other-oriented perfectionism (OOP), Socially prescribed perfectionism (SPP) - and burnout. To do this study, 250 data collected from people who would be over 20 years old in the country using Korean Version of Hewitt's Multidimensional Perfectionism Scale, Korean Version of Workaholism Battery, Maslach Burnout Inventory. To analyze the result of the questionnaire survey, Descriptive statistic, correlation analysis, t-test, regression analysis, two-way ANOVA were performed using SPSS. As a result, the interaction between SPP and workaholism showed the meaningful effect on burnout. In other words, while SPP lower group experiences less cynicism regardless of the degree of workaholism, SPP upper group experiences noticeable more cynicism when they are in the lower workaholism group, suggesting that workaholism may have a positive effect of making someone experience less burnout.

  • The purpose of this study is to produce time-distance cartograms based on the various Korean transportation networks, and to analyze the spatial structure of time-distance accessibilities. For the purpose this study attempts to develop continuous area cartogram by utilizing Wolf's algorithm for creating contiguous cartogram in ArcGIS 9. The absolute physical space was transformed to the functional space indexed by time-distances along various transportation networks in Korea. We examined the differences in the time-distance accessibilities among transportation networks. This study makes a comparison between the spatial structure of time-distance accessibility of KTX network with them of existing railroad network, as well as with them of road network. In order to clarify the spatial structures of time-distance accessibilities, we restructured them on the time-distance circular diagrams and performing Multi-Dimensional Scaling analysis. Overall structure of time-distance accessibilities shows similar patterns: The time distances are shrinked a lot along the Seoul-Busan axis, while coastal parts, in particular the eastern part of the county, are shrinked relatively little via all transportation networks. The Road network affects significantly on the accessibilities of cities in Gangwon-do and Gyeonggi-do, while railway network affects on the accessibilities of cities in Jeolla-do and Gyeongsang-do in general. When we compared the time-distance accessibilities based on the 5 largest cities, Seoul appears as the most accessible city from/to all other cities in Korea. We can also find significant changes in the time-distance accessibility between KTX network and existing railroad network. Cities along the KTX network, in particular cities which has KTX stops, improved significantly in time-distance accessibilities.

  • This study attempts to develop the scale of 'Caregiving Affirmation Scale' for Korean Caregivers for the Aged and to testify the possibility of generalizing the scare. Mixed methods of qualitative and quantitative researches were used to achieve the purpose of the study. The steps of developing the scale were proceeded as follows: Firstly, 40 items were identified through the qualitative study and the literature reviews. Secondly, the content validity was verified through the professional group survey in addition to confirm the questionnaire items by the 1st survey. And thirdly, the construct validity and concurrent validity of the factors of 'Caregiving Satisfaction' were explored by performing the 2nd survey. As the results of the study, the total 16 items of 'Caregiving Affirmation scale' identified with the four sub-factors as follows; 1) Improvement of the care skill and a sense of fulfillment; 2) Possibility of contributions to other persons; 3) Acceptance of the aged; and 4) Improvement of Self-value. The reliability value of Cronbach's α was 0.89 with the high internal consistency and the confirmatory factor analysis showed the relationship between the items and each factor were also statistically significant. Thus, the content validity was verified. Also the correlation with the affirmative care recognition and the life satisfaction was 0.65, which meant the concurrent validity exists. The Caregiving Affirmation Scale for Korean Family Caregivers for the aged is expected to be used at the social welfare practice settings for the aged.

  • 기존의 감성 연구들은 주회 배색이나 형태등과 관련된 정적인 장면 위주로 수행되었다. 기술의 발달로 역동적인 디스플레이가 가능해지면서 동적인 장면을 대상으로 한 감성연구의 필요성이 요구된다. 본 연구에서는 움직임과 관련된 감성어휘를 추출하여 감성 차원을 밝히고 움직임과 관련된 속성을 살펴보았다. 다양한 방법을 통해 수집된 감성어휘를 적절성 평가를 통해 70개로 정리한 뒤 요인분석을 통해 각 요인을 대표하는 19개의 기본 감성 어휘를 추출하였다. 움직임 패턴을 제시하면서 19개의 감성어휘를 기초로 움직임에서 의 감성을 평정하도록 하였다. 다차원 척도법을 이용하여 분석한 결과 움직임에 대한 감성 차원은 '적극적이다-소극적이다'의 차원과 ‘밝다-어둡다’의 두 차원으로 대부분 설명 될 수 있음을 확인하였다. 움직이는 속도와 진행 경로를 변화시키면서 두 가지 감성 차원에 따라 움직임에서의 감성을 평가하도록 하였다. 움직이는 속도와 곡선 경로의 진폭이 움직임에서의 감성 차원을 결정하는 중요한 요소로 작용하는 경향을 보였다.

  • As sustainable growth has been emphasized in the field of transportation, the railway system has been promoted as an environmentally-friendly transport mode. However, mode shifts from other transport modes to railway have been sluggish. In this context, to enhance the understanding of railway's competitive advantages and disadvantages, this research evaluates travelers'preferences for public transport modes for inter-regional trips: such understanding should make it possible to formulate effective policy for promoting railways. To this end, passenger recognition of competitive transport modes has been measured by applying multidimensional scaling analysis for six major inter-regional public transport services - KTX, ITX-Samaeul, Mugunghwa-ho, premium express bus, general express bus, and airline. As a result, we can conceptualize the recognition similarity in two-dimensional space, and understand how travelers perceive the six major transport modes.
