ln competitive electricity market, useful technique would be required to calculate settlement amount for electric power traded between market participants and KPX since a number of market partici-pants would appear and trade electric power. Especially calculation of constrained on/off compensation amount can be complicated, and needs to be understood clearly by market participants to avoid unnecessary disputes. This paper presents a technique to settle more easily constrained on/off compensation amount using surplus function. In this technique, a surplus is calculated by each dispatched values and then the compen-sation amount is calculated by the difference of each surpluses. By doing this, settlement amount can be cal-culated by summing the trading amount and the compensation amount.

This study aims at looking into constraints of physical activity amid "after school" programs operated by an elementary school of Incheon City. For this study, 330 elementary school students of Incheon City were sampled, and tested of descriptive statistics, explanatory factor analysis, Cronbach's alpha, One-way ANOVA, independent t-test, and confirmatory factor analysis by Raymore, Godbey, Crawford's questionnaire. First, examining difference of constraints in accordance with the demographic variables of physical activity participants. Second, analyzing probing and confirmative factors and reliance of leisure constraints for physical activity participants. Third, examining the relations of cause and effect between factors of leisure constraints of physical activity participants and participation.

This study aims to investigate overall factors regarding participation process such as process to pro-environmental behavior, pro-environmental behavior, continuing factors and constraint factors of outdoor recreation participants, and to determine logical correlation between them in order to make a theory model. To this end, grounded theory approach is applied for interpretation. First, pro-environmental behavior of outdoor recreation participants was formed by sequential influence of causal conditions and situational context. Second, outdoor recreation participants who participated in pro-environmental behavior of central phenomenon experienced peculiar continuing factors and constraint factors but it was found they also experienced general continuing factors and constraint factors. Third, it was analyzed that resultant settlement of pro-environmental leisure activities was partially fed back to the participation continuing factors of mediating conditions and a club of interaction strategy. Result from this study will give a help to widely understand experience of participation in leisure and restraints on leisure of outdoor recreation participants, and to development of study through organic combination between subsequent researches.

The purpose of this study was to investigate leisure constraints based on the types of leisure sports activity(individual, partner, and group activities) in order to lead people to participate in and to continue their leisure sports activities. Data were collected from leisure sports participants in Seoul and Kyungki province. A total of 286 respondents were selected using the convenience sampling method. Leisure constraint's sub-dimensions for the respondents were named as facility and environment, negative perception, lack of condition, risk of injury, and lack of time. As the results of this study, first, respondents felt facility and environmental constraint the most and negative perception constraint the lowest. Second, there were differences in negative perception and lack of condition constraints based on the magnitude of participation. Finally, there were differences in facility and environment, negative perception, lack of condition, and risk of injury constraints based on the types of leisure sports activity.

본 논문에서 수요 자원의 수요 반응 프로그램 참여에 관한 정보들을 등록 정보와 참여 정보로 구분하여 수요 자원의 특성을 나타내는 지수들로 구분한다. 이 지수들은 수요 반응 참여 가능 용량, 기간, 횟수, 한계 비용에 관하여 정보를 제공하며 이들을 바탕으로 수요 자원을 하나의 발전 자원으로 평가한다. 이로써 수요 자원은 발전 자원과 직접적으로 경쟁할 수 있으며 계통 운영자는 수요 자원을 운영 계획에 포함한다. 계통 운영자는 발전 및 수요 반응 비용을 최소화하여 운영 계획을 수행하는데 이때 발전 자원과 수요 자원의 제약 조건을 위반하지 않아야 한다. 본 논문에는 기존 개발된 발전 자원의 제약 조건으로부터 수요 자원의 제약 조건을 제안한다.

Objective: The purpose of this study was to suggest predictors of participation restriction in community-dwelling Spinal Cord Injury (SCI) based on environmental, functional, injury-related, psychosocial, and sociodemographic factors. Methods: The participants were 82 community-dwelling SCI adults over the age of 18. They were all included in the American Spinal Injury Association's (ASIA) Levels A, B, and C. This study surveyed participants' participation using the CHART-K-SF, environmental factors using the CHIEF-25 Korean version, and functional factors using the SCIM III. Further, pain and distress were surveyed using Zung's Self-rating Pain and the PAD, self-esteem was assessed using the RSES, and self-efficacy using the GSS. Finally, information concerning injury levels, post-injury period, causes of injury-related factors, and sociodemographic factors such as gender, age, marriage, education level, and residence information were collected. The collected data were analyzed using SPSS Version 21.0 Results: Participants' risk factors were environmental and functional. The Nagelkerke's $R^2$ was.737. The OddsRatio(OR) of environmental factors(referent,0-1) was 40.346. Moreover, the OR of the $1^{st}$ quartile functional factor(referent,4thquartile) was 236. 621, and that of the$2^{nd}$ quartile was 21.174. In addition, the occupational predictors included the "policies" subscales in the CHART-K-SF, "physical/structural" in the CHIEF-25, and "mobility" in the SCIM III. Further, the predictors of "physical independence" were "services/assistance" in CHIEF-25, and "respiration and sphincter management' on the SCIM III. Additionally, "mobility" was predicted by "physical/structural" on the CHIEF-25 and "mobility" on the SCIM III. Conclusions: This study multidimensionally confirmed predictors of participation restriction. Through these facts, we investigated occupational therapists' roles in community setting. Therefore, this study's results will provide useful information for occupational therapy services, for which the goal is SCI participation improvement within the community.

The point of the meaning, this study selects population which is aged over 65 and new silver generation who is aged between 55 to 64. The objects were selected by purposeful sampling method and the 933 objects who participated in leisure sports age over 55 were used for this thesis's analysis. The results of the study were as follow; First, the weekly participation frequency was physical psychological burden, facilities, information technology, interpersonal relations, concern lack, time lack, bear. there was statistically significant difference. Second, the daily workout time was physical psychological burden, facilities, information technology, interpersonal relations, concern lack, time lack, bear. there was statistically significant difference. Third, the participant experience was physical psychological burden, facilities, information technology, interpersonal relations, concern lack, time lack, bear. there was statistically significant difference.

This study identified the relationship between leisure attitudes, leisure promotion, leisure drugs, leisure satisfaction, and the intention to rejoin maritime sports by the participants of this study. The researchers selected 542 adult men and women who live in Seoul and the Incheon, Gyeonggi and Chungcheong provinces, and who were currently engaged in marine sports activities. Data processing was performed using SPSS 21.0 and AMOS 18.0 for the frequency analysis, reliability analysis, confirmatory factor analysis, correlation analysis and structural equation model analysis. The results of this study were as follows. First, the leisure attitudes of marine sports participants did not affect the promotion of leisure (p>.05). Second, the attitude towards leisure of the marine sports participants had a negative effect on using leisure pharmaceuticals (p<.05). Third, the leisure attitudes of marine sports participants affected their leisure satisfaction (p<.05). Fourth, the promotion of leisure activities of the marine sports participants did not affect their leisure satisfaction (p>.05). Fifth, the leisure restrictions of marine sports participants did not affect their leisure satisfaction (p>.05). Sixth, the leisure activities of marine sports participants affected the intention of rejoining (p<.05).
