This study involved using carefully selected fariry tales to effect children's peer competence and aggression. The subjects of this study were 41 four-year-old children from two private kindergarten in I city, South Korea. All subjects were from similar financial backgrounds and were divided into two groups: the experimental group(n=21) and a control group(n-20). The experimental group was given activities related to personality education after listening to fairy tales for 30 minutes every week, and the comparative group was given general daily routine operation. The collected data were analyzed by ANCOVA analysis using SPSSWIN 18.0. The results of the study showed that the experimental group had significantly higher peer competence than the control group and lower aggression. These results suggest that character education activities using fairy tales can have a positive effect on young children's peer competence and aggression.

Traffic accidents occur in Korea are calculated with the 「Automobile Accident Negligence Ratio Certification Standard」 prepared by the 'General Insurance Association of Korea' and the insurance company's agreement or judgment is made. However, disputes are frequently occurring in calculating the negligence ratio. Therefore, it is thought that a more effective response would be possible if accident type according to the standard could be quickly identified using traffic accident information prepared by police. Therefore, this study aims to develop a model that learns the accident information prepared by the police and classifies it to match the accident type in the standard. In particular, through data mining, keywords necessary to classify the accident types of the standard were extracted from the accident data of the police. Then, models were developed to derive the types of accidents by learning the extracted keywords through decision trees and random forest models.

기후변화 위기는 유사 이래 인류가 직면한 가장 큰 도전으로 범정부적 글로벌 문제로서 이를 해결하기 위한 다양한 정책들이 범국가 차원 혹은 세계적 기업들에 의해 발표 혹은 시행되고 있다. 이러한 기후변화위기와 탄소배출 저감을 위한 대표적인 대응 방안 중 하나가 바로 재생에너지의 확대·보급 노력이다. 그러나 재생에너지는 날씨와 계절 등 자연환경의 영향을 받는 에너지원으로써 간헐성, 변동성을 가지므로, 시간대별 발전량 예측과 전력공급 안정성에 어려움이 있다. 이러한 문제를 해결하기 위하여 재생에너지 발전은 석탄화력 발전과 달리 전력의 수요와 공급의 균형을 위한 에너지저장장치(Energy Storage System, 이하 ESS)가 있어야 한다. ESS는 전력공급 안정성 향상과 전력 수급의 유연성을 제공하는 장점이 있지만, 초기 설치비용이 높은 단점이 있다. 특히, 배터리 기반 ESS의 경우 높은 구축 비용과 한정적인 충. 방전수명으로 인하여 대용량 ESS로써의 역할 수행에는 분명한 한계가 있다. 하지만 재생에너지와 연계한 ESS로 양수발전댐을 활용할 경우 장주기, 장수명, 대용량 에너지 저장에 매우 합리적인 수단으로 판단되었다. 다만, 양수발전 댐 구축에는 토목공사로 인한 환경 훼손이라는 문제점도 존재한다. 본 고에서는 지역 분산형 소규모 양수발전(Pumped Storage Hydropower, 이하 PSH)댐 구축 및 운영기술 개발을 통해 지역 전력공급과 전력 수급을 조절하면서 변동성 재생에너지를 안정적으로 사용할 수 있는 방안을 소개하고자 한다. 특히, 해당 기술은 지역별 특성에 맞춰 유연하게 설치할 수 있으며, 대규모 토목공사로 의한 환경적 부작용을 최소화할 수 있다. 또한 소규모 PSH는 지역의 저수지 및 수자원을 이용하여 에너지를 저장함으로써 변동성 큰 재생에너지의 유연화 대응과 동시에 안정적인 에너지 공급이 가능하다. 본 고에서는 재생에너지의 확대·보급에 따른 문제점과 대표적 ESS 기술들을 분석·소개한다. 지역분산형 소규모 PSH 기술개발 연구기획 내용 소개를 통하여 전력 생산 및 공급의 탈중앙화를 달성하고, 지역별 변동성 재생에너지의 안정적 활용과 지역 전력공급 특성 및 전력 수급에 대응할 수 있는 방안을 제안하고자 한다.

As society has more interest in reading activities, it has become possible to secure social value of libraries through the promotion of reading. In this regard, the study aimed to analyze social tasks that the libraries face and suggest concrete methods through bibliographical examination. Currently, various regions of the nation have an increasing interest in libraries, particularly, children's libraries. The public libraries can expand their social roles by meeting these social requests. As a variety of activities by the public libraries to promote reading have helped people recognize the importance of libraries, more aggressive reading promotion activities are considered to help expand the roles of the public libraries and secure social base. Accordingly, the libraries need to take the initiative in implementing various measures by establishing a committee to adjust various reading promotion activities in the government and the public and private sectors, coming up with legal base, pursuing development of voluntary reading promotion programs, establishing an information network for reading and books, publishing book reviews, leading campaign for reading and reading promotion activities, supporting reading at home and expanding award system with regard to the promotion of reading.

Modern society is operated based on the internet, wireless networks, and digital devices to the extent that it is called a digital society. In particular, as most of financial transactions, information movement, and commercial activities are based online, various social problems and side effects related to this are increasing rapidly. Representative examples include industrial espionage activities and leakage of industrial technology, and social problems such as illegal goods trade such as drugs using online and online gambling are increasing to a serious level. These digital-based social problems cannot be solved only by the activities and capabilities of judicial institutions such as police and prosecutors. Now that the private investigation market is open, active intervention using them is necessary. To this end, it is necessary to actively cultivate private investigator's ability to investigate and collect evidence in relation to digital social and criminal problems. In addition, each private investigation education institution or association should actively invest and research this.

This study is about the status and comparison of recreational scuba diving certification system in Southeast Asia countries. For the collection of the information, the contents of the numerous corresponding Internet sites were utilized, related documents were surveyed. And to supplement the information extensive interviews were held with the representatives of tourism department of many countries as well as staffs of diving associations, resort operators and diving instructors during various 2007 Dive Expos held in Southeast countries. In this paper, the relation between scuba certification and international standards were introduced for better understanding of the certification system. The research result shows that the scuba diving industry plays an important role in their country's tourism and the certification market of the Southeast Asia has grown to be greater than 30% of the world total market. However due to the facts that the scuba activity is originated from the western world and the controlling headquarters of the most certification agency are also located there, Southeast countries cannot take any leading roles in the scuba diving policies and systematic issues. Accordingly any modifications or improvements are expected to be very difficult. Also while Europeans and Americans have launched the programs and organizations for the quality assurance by cooperating with the international standards, but no such activity has yet appeared on the surface in Southeast Asia. According to the investigation the necessity will become bigger in near future.

The purpose of this study were to assess main management components that can lead to successful university foodservice operations. Specifically, it was intended to develop the tool which assesses the service quality, management, to assess the difference between customer importance from and perceptions of service quality, to compare management perceptions of customer importances with actual service delivery, and to identify internal problems which affect service quality with the use of gap model. Three types of questionnaires were developed and implemented for customers, foodservice personals and foodservice manager. Assessment tools were developed based on the literature review, SERVQUAL, GAP model, and the pilot study. Through the validity and reliability test, the questionnaires were revised. Questionnaires were distributed to 900 university students, 207 foodservice personnels, and 54 foodservice manager respectively. 831 university students, 177 foodservice personnels, and 48 foodservice manager were responded with a response rate of 92.3%, 85.5%, and 88.8% respectively. Statistical data analysis was completed using the SPSS programs for descriptive analysis, ANOVA. and SNK test. The results of this study can be summarized as follows : 1. In quality service management components, 31 quality service attributes were categorized and named into primary quality, secondary quality, hygiene, empathy, tangibles, reliability, responsiveness, and price by the factor analysis. 2. Importance mean score of customers was 4.02 out of 5, but perception mean score of customers was 2.55. So there was a relative big gap(1.47) between importance and perception scores, especially in three dimensions of responsiveness, primary quality, and hygiene. 3. It showed that customers' mean scores of perceived service quality by dimensions were the following order : price > reliability > secondary quality > hygiene > tangibles > primary quality > responsiveness > empathy. And the perception mean score of rented(2.59) or contracted(2.58) management was significantly higher than that of self-operated(2.48). 4. Customers' importances mean score which internal customers recognize was 4.23 out of 5, but service delivery mean score was 3.85. So there was a little gap(0.39) between management perceptions of customer importances and actual service delivery. 5. In gap model, SERVQUAL score showed -1.47, Gap 1 positive 0.15, gap 2 negative 0.61, and gap 3 was positive 0.19. 6. The internal problems were as follows : (1) The managers of University foodservice perceived well enough the customers' expectation value but their management competency was lacked in terms of responding customer needs, (2) The foodservice staff perceived service performance more highly than service quality specifications.
