This study investigates both arbitrariness and misrepresentation in the terminology of Korea's LIS field with an example of the term 'information services.' The focus is on analyzing the differences in the Term's history and theoretical base between American LIS field and Korea's. Discussed in details are the popularity and usage of the Term in Korea's LIS field and libraries. The ultimate intention of this study is to motivate the Korea's LIS scholars to endeavor for theoretical accomplishments with regard to 'information services,' which can justify the change of term from 'reference services' to 'information services.'

Recently in the area of the information environment, there are lively discussions about search 2.0 which is representative of the next generation search services. In this study, we divide information search model into matching and linking models according the developmental stages. Therefore, on the one hand, we analyze the background, main concepts, related attributes and cases of the next generation search services and the other, we identify the representative keywords by the group analysis of various attributes and cases of it. The result shows that the main keywords such as social search, artificial intelligence and semantic search, and relation/network based search are representative of the search 2.0.

This paper describes on the initial procedure of the concept development for marine waste cleaning ships and her fleets. We investigated and analyzed about missions, operating ocean environments; similar cleaning ships, laws and regulations for determining the functional requirements of ships and fleets, and then top-level requirements were drawn out. According to the volume estimation of marine wastes in domestic coastal and shoreline, we made the alternatives, combination of some design factors, for the evaluation of economical efficiency. As a result of this study, we organized the fleets of marine waste cleaning ships adapted to the environments of domestic coastal.

We can launch satellites only at a certain time which satisfies special conditions, since the current techniques cannot overcome these constraints. Launch window constraints are the eclipse duration, solar aspect angle, attitude control, launch site and the launch vehicle constraints, etc. In this paper, launch window is calculated that satisfies all these constraints. In calculating launch window, the basic concepts are relative locations of the sun-satellite-earth system and relative velocities of these, and these requires geometric consideration for each satellite. Launch window calculation was applied to Kitsat 2(low earth orbit) and Koreasat(geostationary orbit). The result is shown in the form of a graph that has dates on the X-axis and the corresponding times of the given day on the Y-axis.

Child abuse is becoming the cause of runaway young people and is related with the criminal act and the misconduct occurrence. Seriously, the social problem which raises is that the abused child has become the adult, again the children of oneself will abuse again. On the based of the research, this study reviewed the concept of the child abused, the type of the child abused, the theoretical approach of the runaway and juvenile delinquent. The runaway youth compare to the general youth that the abused child was significant p<.05. Base on the data the police officer reviewed the assistance for the abused child.

Present work deals with a shape optimal design to minimize the weight of the mask-frame used in the process of OLED vapor deposition by the fine metal mask. A design concept for an optimal shape of the frame to increase the stiffness and to reduce the weight is derived using the topology optimization, shape design variables of the frame by adopting slots being defined. An optimal shape is determined by solving the shape optimization problem to minimize the weight of the frame under constraints of the maximum displacement. Weight of the optimal design is 117.6 kg, which is reduced by 138.4 kg(54.1%) of that of the first design, 256 kg.

FRBR and FRAD model, ICP, RDA, NCR Revision are analyzed for the composition of KCR4 Revision. Based on the results, follows are suggested. 1) Entities are divided into work, expression, manifestation, item, person, family, corporate body, concept, object, event, place. 2) Entire cataloging rules are grouped into 'attributes' and 'relationships', and then 'attributes' is divided into attributes describing and access points constructing. 3) Attributes describing is divided into attributes describing of works, expressions, manifestations, items, persons, families, corporate bodies, and arranged as the sequence. 4) Access points constructing is divided into access points constructing of works, expressions, persons, families, corporate bodies, and arranged as the sequence. 5) 'Relationships' is divided into other relationships between group 1 entities, and relationships between persons, families and corporate bodies.

최근 자연재해로 인한 피해가 늘어남에 따라 피해를 최소화 하기위한 방법들이 절실히 필요한 실정이며 또한 자연재해로 피해를 입은 지역을 복구하는 과정에서 여러 기관들의 업무 중복 및 누락으로 인하여 재해 관리의 효율성이 떨어지고 있다. 따라서 재해에 대비한 지속가능한 기술개발과 효율적 복구기법 개발을 통한 피해의 연구가 절실한 실정이다. 본 연구에서는 해외의 재해 복구사례들을 통하여 복합피해지역 지정개념을 소개하고 재해복구 조직 및 기법을 검토하였다. 연구를 위해 먼저 국내의 복합적 재해발생 현황 검토와 각종 해외 종합복구체계 조직 및 기법을 검토하였다. 특히 허리케인 카트리나에의한 미국 뉴올리언스주의 복구체계 및 복구사례와 중남미와 아시아 등 지난 20여 년간의 복구사례에 대한 유엔의 보고서를 중심으로 단 장기적 복구계획과 실시사항들을 검토하였으며 적용된 복구범위 설정 및 조직의 업무 분담 및 공조체계를 통해 효율적인 복구계획 마련과 추진과정에 대한 방안들을 검토하였다. 사례분석을 통해 모여진 자료를 토대로 외국사례들이 어떻게 국내 실정에 맞게 적용되고 효율적으로 사용될지에 대한 검토의 과정을 거쳤으며 이러한 과정을 통해 종합재해복구기법 선정을 위한 검토항목 및 평가기법을 제안하였다.

The 7th curricula of computer education as a general subject for secondary schools in Korea has relatively stressed on the application softwares as a learning tools. Such approach might be very successful in terms of ICT literacy education, but it is not enough to teach fundamental concepts and principles of information technologies and computer science and it has also limitation to apply such knowledge to expand students' intellectual capabilities. Therefore, in this paper we first investigates the reason of introducing computer science principle education according to IT fluency and show appropriate direction of computer education curricula for secondary schools.
