  • 현재 초,중,고등학교에서 사용하고 있는 책상과 의자는 학생들의 신장 등급에 따라 13호로 제작되 고 있음에도 불구하고, 신체부적합에 의한 편이도. 안전도에 문제를 안고 있다. 이러한 책상과 의자는 특히 장시간 앉아 있는 성장기 청소년의 신체 발달을 고려하지 않음으로 인해 그 개선책이 시급하다 하겠다. 다라서 본 연구에서는 설문조사를 통하여 초,중,고등하교 학생들의 감성적 선호도를 조사하 고, 1992년 표준과학연구소의 부위별 신체 측정 자료를 토대로, 자유 조절형의 인체공학적 책상과 의자 를 설계하였다. 이 인체공학적 설계는 한 호수의 제품으로 색상 4단계, 의자 3단계(조합 12 단계)조절 을 가능하게 했으며, 기존의 교구에서 발생하던 신체 부위 상해, 잘못된 자세로 인한 피로, 디자인적 고 려 부재의 문제들을 종합적으로 보완하였다. 이 인체공학적 책상과 의자는 표본 집단에서 그 편이도, 안전도, 개인적 선호도를 조사하여, 기존의 교구와 유의한 차이를 보였다. 중 저가로 제작 가능한 본 인 체공학적 책상과 의자는 실제초,중,고등학교에서사용 가능한 제품으로 사료되나, 본격적인 판매에 앞서 완제품에 대한 시장 평가가 요구된다.

  • The purpose of this study was to examine the relationship among physical self-concept, leisure sport participation satisfaction, and leisure sport participation level. By analysing a total of 353 university students participating in leisure sport with structural equation modeling through AMOS 20.0 statistics program, this study found the followings. First, the physical self-concept has a positive influence on leisure sport participation satisfaction. Second, leisure sport participation level has a positive influence on leisure sport participation satisfaction. Third, there was no significant mediating effect of leisure sport participation level on the relationship between physical self-concept and leisure sport participation satisfaction.

  • The purpose of this study was to examine the effect of coaches' transformational transactional leadership on athletes' self-efficacy among high school students. A total of 400 high school athletes from S and D city were selected through the convenience sampling method. A total of 258 questionnaires were returned and 39 were discarded due to missing values. Therefore, a total of 219 questionnaires were analyzed using SPSS 20.0. This study found the following: First, the intellectual stimulation of leadership had the greatest effect on self-regulated efficacy of self-efficacy. Second, inspirational motivation of leadership had the greatest effect on confidence of self-efficacy. Third, leadership factors did not affect task difficulty preference of self-efficacy.

  • This study attempted to verify what motivates fans to follow college sports teams' social media and identify the motivational factors that can best predict fans' social media consumption. Confirmatory Factor Analysis (CFA) indicated that previously identified seven motives for online consumption, i.e., information, diversion, socialization, pass-time, fanship, team support, and technical knowledge, are compatible with the use of college sports teams' social media. In addition, a results of multiple regression found diversion, socialization, fanship, team support, and technical knowledge to significantly predict the level of social media consumption while information and pass-time did not significantly affect social media consumption. In particular, socialization had the greatest influence on social media consumption.

  • The purpose of this study was to investigate the relationship among leisure constraints, athletic life satisfaction and self-control of student athletes at physical education high school. By using convenience sampling method of non-provability sampling, a total 217 students athletes from D and G city were selected. Of 217 copies of the questionnaire gathered, 35 were discarded owing to having excessive missing values. Thus by analysing a total of 182 surveys with structural equation modeling through SPSS 20.0 statistics program, this study found the followings. First, leisure constraints have a negative influence on athletic life satisfaction. Second, leisure constraints have a negative influence on self-control. Third, athletic life satisfaction has a positive influence on self-control.

  • 수문자료의 빈도해석은 자료의 독립성(independence)와 정상성(stationarity)를 가정하여 이뤄진다. 그러나 관측 수문자료에서 비정상성 현상이 발생하고 있다는 사실이 관측되면서 수문자료에 대한 비정상성 빈도해석에 대한 필요성도 커지고 있다. 본 연구의 목적은 수문자료의 빈도해석에서 가장 널리 사용되고 있는 Gumbel 및 GEV 분포에 대한 비정상성 빈도해석 모형을 개발하는 것으로, 이를 위해 비정상성 Gumbel과 GEV 모형의 매개변수를 시간에 따라 변하는 형태로 정의하였다. 비정상성 Gumbel 및 GEV 모형의 정확도를 알아보기 위해 비정상성 모형과정상성 모형을 이용하여 Monte Carlo 모의실험을 수행하였다. 모의실험은 다양한 조건의 재현기간, 표본크기, 매개변수 조건을 고려하여 수행되었다. 그 결과 비정상성 모형의 오차는 비교적 표본크기가 클 때 가장 작은 것으로 나타났다. 또한 복잡한 매개변수의 조합을 가지는 비정상성 모형은 모두 동일한 경향성을 가질 때 가장 작은 오차를 보이는 것으로 나타났다. 비정상성 GEV 모형의 경우는 확률수문량 산정에 음(-)의 형상 매개변수가 큰 영향을 끼치는 것으로 나타났다. 또한 본 연구에서는 비정상성 조건에서 다양하게 존재하는 비정상성 모형 중 어떠한 모형이 주어진 자료에 대해 가장 적절한 모형인지 결정하기 위해 모의실험을 수행하였다. 널리 적용되고 있는 AIC, BIC, likelihood ratio test에 대해 정상성 및 비정상성 Gumbel 모형을 이용하여 모의실험을 수행한 결과, AIC가 비정상성 모형 중 적정 모형 선택에 가장 효과적인 것으로 나타났다. 개발된 비정상성 Gumbel 및 GEV 모형의 적용성을 알아보기 위해 우리나라 연최대강우 자료에 적용한 결과, 위치 매개변수에 시간항을 고려하는 Gumbel 모형이 최적모형으로 가장 많이 선택되는 것으로 나타났다. 따라서 현재 우리나라의 연최대강우자료 중 경향성이 나타나는 자료에 대해서는 위치 매개변수가 시간에 따라 변하는 특성이 가장 많이 나타나고 있는 것으로 판단된다.

  • This study conducted a survey to evaluate the disaster response capability of coastal residents and analyzed the characteristics. For the sampling process, nonrandom sampling method was used. Sample size is 4,520 and sample error is ${\pm}1.5%p$ at 95% confidence level. As a result of the survey, 72% and 68% of the respondents said that they recognized the emergency contact network and listened to the disaster broadcast. On the other hand, 17% and 18% said that they organized the local voluntary disaster prevention teams and participated in disaster preparedness training. In addition, male's disaster response capability was higher than female's, and first aid techniques and participation in disaster preparedness training were higher in teens and twenties. By occupation, public official possess the highest response capability. By region, it was high in the East coast and low in the South coast. It is necessary that the authorities improve the national disaster preparedness training and publicity to enhance the coastal disaster response capability of coastal residents.

  • This paper aims to explore the citation patterns of conference papers in 'Information Science' discipline and to analze impacts of various cited works-related factors on future citations of conference papers. Existing bibliometric studies has investigated citation patterns and the statistical relations between a variety of bibliographic factors and the future citations of literature. However, the attentions have been focused largely on journal articles, and the bibliometric studies targeting conference papers are still in an infant stage. Therefore, this study, which is based on 1,904 conference papers in 'Information Science' field, examined several citation patterns and the contributions of the factors about cited works - the number of cited works, type of cited works, citation rates and ages of cited works at the time of being cited and the rate of self-citedness - to the future citation of the citing target articles. The data source of this study including the properties of target articles and cited works and citation rates of target articles was Scopus. As the results, 53% and 29% of the cited works were conference papers and journal articles, respectively. 14% of them are non-traditional types such as web pages, technical reports, patent, etc. More than 60% of the cited works were 5 years old or less. Among several factors considered in this paper, the number of conference papers and the number of non-traditional types of works are the most contributing factors on the citation rates of target articles. The recency of the cited works is also significant contributor on the citation rates of target articles. That is, the target articles citing more conference papers and non-traditonal types of works earned more citations. The target articles citing recent works also earned more citations.

  • This study was conducted to research the Selection Attribute for Pension which is located in the region of S. Gyeonggi-do. We intended to find the best choice point for reserving the pension using IPA and suggest or provide strategic implications and marketing method for running the pension. The survey was conducted from the early January to the end of March in 2012 with one to one method. A total of 300 questionnaires were distributed and 229 responded questionnaires were reliable to be used as a sample. The result of the survey was analyzed by using SPSS 15.0 version for window with Paired t-test and IPA method. Frequency Analysis was also conducted for the characteristic of samples. Findings are presented and discussed in three areas. First, the cleanliness of rooms, service for customer, heating and cooling system are the key important factors for the choice of pensions. Secondly, all factors are statistically significant level(p<0.01, p<0.001) as a results of performing IPA method. Thirdly, the result has shown that the varity of programs in the pension have significant impact on the customers' choice and satisfaction.
