It is required to enhance the value of ISBN as a tool for book search, identification, browsing, and improve the accessability and search capability of library OPAC. Bookmarklet is a small size javascript which can be saved as URL in a web browser bookmark or web page hyperlink. Open source bookmarklet can extract ISBN from web pages and search a book from library OPAC using the ISBN, so it is recognized as a simple but powerful search tool. In foreign countries, commercial library system vendors, libraries, OCLC, etc. are providing bookmarklets which allow a user to search for library holdings and loan information in a real time while he/she is travelling in an online bookshop web page. Therefore, this paper compared and analyzed international bookmarklets application examples and proposed LibraryLookup service in which library OPAC and online bookshop can make use of the bookmarklets.

Recently, an intelligent service robot is being developed for use in guiding and providing information to visitors about the building at public institutions. The intelligent robot has a sensor at the bottom to recognize its location. Four wheels, which are arranged in the form of a lozenge, support the robot. This robot cannot be operated on uneven ground because its driving parts are attached to its main body that contains the important internal components. Continuous impact with the ground can change the precise positions of the components and weaken the connection between each structural part. In this paper, the design of the suspension system for such a robot is described. The dynamic model of the robot is created, and the driving characteristics of the robot with the designed suspension system are simulated. Additionally, the suspension system is optimized to reduce the impact for the robot components.

21세기를 맞이하여 대학도서관은 정보기술의 도입, 업무내용의 변화, 이용자의 요구변화등 급격하게 변화하는 새로운 환경에 직면해 있다. 본 연구는 한국의 대학도서관 조직구조의 현황에 대한 분석과 함께 다양한 조직이론들과 정보환경의 변화에 기초해서 도서관조직을 활성화시키기위한 개념적인 조직모델을 제시하고자 한다. 한국의 대학도서관은 거의 10년동안 법적인 제약과 조직내외의 환경적인 한계 등으로 인해 전산화시스템의 도입, 도서관부관장의 임명, 그리고 도서관과 컴퓨터 센터와의 통합시도와 같은 약간의 변화외에는 거의 변화가 없었다. 전형적인 한국의 대학도서관은 수서, 기술서비스, 열람과 참고봉사 부문으로 조직되었다. 여기서 수서 기능을 기술서비스의 부문으로 간주한다면, 본 연구의 대상인 대학도서관 114개관 중 95개관(82.5%)이 전통적인 도서관조직의 형태인 기술서비스와 공공서비스 부문으로 조직된 것으로 나타났다. 본 연구에서는 전통적인 도서관조직의 문제점들을 급복할 수 있는 21세기의 개념적인 대학도서관 조직모델로서, 네가지 부문 - 서비스 부문, 서비스지원 부문, 기술지원 부문, 그리고 통합·조정부문-을 대학도서관의 개념적인 기본 구성요소로써 제안하였다. 그러나 모든 도서관의 서비스나 업무과정에 대해 적합한 잉상적인 조직구조는 없으며, 조직의 재조직과정은 도서관의 형태와 목적, 업무과정에 따라 매우 다양하다. 따라서 도서관의 재조직화는 환경의 변화에 따라 끊임없는 과정이 될 것이며, 도서관조직의 성공은 이러한 변화에 적응할 수 있는 개인과 조직의 역량에 달려있다고 하겠다.대한 순서에 있어서 차이가 있다. 4) 도서관에 대한 태도에 있어서 두 집단은 상이한 입장을 보이고 있다. 학자들의 과반수는 중요 정보원으로서 자신의 개인장서를 활용하며, 도서관의 장서 및 그 조직방법에 대해서도 별로 만족하지를 못하고 있다. 반면에, 실무가들은 도서관에 대하여 비교적 만족하며 따라서 도서관에 대한 이용도도 높다. 5) 두 집단 모두 보조인을 적극적으로 활용하지 않으며 사서의 도움을 받는 경우도 극소수에 불과하다. 이러한 조사결과를 기초로 하여 볼 때 법률전문직을 둘러싼 정보환경을 개선하기 위하여는, 인쇄된 일차적 정보자료의 검색방법등을 개선하고, 나아가서는 법령과 판례정보를 위한 효율적인 시스템을 구축하며, 뿐만 아니라 이용자의 요구에 충분히 대처할 수 잇는 도서관으로 변화되는 것이다. 이와 함께 가장 중요한 것은 법과대학과 사법연수원에서 법학 연구방법에 관한 강좌를 개설하여 각종 법률정보원의 활용 내지 도서관 이용방법에 관하여 교육하는 것이다.글을 연구하고, 그 결과에 의존하여서 우리의 실제의 생활에 사용하는 $\boxDr$한국어사전$\boxUl$등을 만드는 과정에서, 어떤 의미에서 실험되었다고 말할 수가 있는 언어과학의 연구의 결과에 의존하여서 수행되는 철학적인 작업이다. 여기에서는 하나의 철학적인 연구의 시작으로 받아들여지는 이 의미분석의 문제를 반성하여 본다. 것이 필요하다고 사료된다.크기에 의존하며, 또한 이러한 영향은 $(Ti_{1-x}AI_{x})N$ 피막에 존재하는 AI의 함량이 높고, 초기에

Since Korea experienced a 'jobless growth' in 2003, creating jobs in the service sector has been considered as a top priority employment agenda. However, despite high employment outcomes in services, labor productivity remains stagnant in the service sector in recent years. A great deal of concern has been raised regarding newly created service jobs. Critics say low productivity in the service sector will harm the engine of economic growth in our country. This paper investigates the side of the demand for quality of labor, namely, the demand for skills as one of the main source of low productivity in the service sector. To analyze the changes of skills demand, this paper suggests the concept of job-based skills instead of worker-based skills and presents the way of constructing measures of job-based skills. By means of common factor analysis using job information in the Korean Dictionary of Occupational Titles, I extract 4 direct measures of job-based skills, such as cognitive skills, physical skills, fine skills, interactive skills. These skill measures are used to explore and to test how the skill structure changed in the service sector during 2002-2006. Empirical Results show that whereas the goods sector makes progress toward upskilling being represented by increased cognitive elements and softenization of tasks, the service sector, although high-educated workers increased, exhibits trends of deskilling in the sense of job-based skills during 2002-2006 in Korea. The trend of deskilling however does not seem a general aspect in the overall service sector. Rather, it seems a compound process that high-skilled jobs are created, but, on the other hand low-skilled jobs requiring physical labor are produced at the same time.

This study looked at how the digital cultural heritage, which is being actively built by the government and public institutions, can be utilized in the metaverse service. Through an expert interview, we investigated how the digital cultural heritage of Bulguksa can be serviced with the four elements of the metaverse: augmented reality, mirror world, lifelogging, and virtual world. As a result of the study, it was confirmed that when digital cultural heritage is used in a virtual space called metaverse, interactive and realistic services can be provided to users. In addition, it was found that users can exhibit, experience, and educate online parts that are not available in real life in the same situation as if they were in the field. Through this, it was confirmed that if digital cultural heritage is designed as a metaverse service, it can provide functions and services of a different level than before. In particular, the result was obtained that it is possible to provide services considering the characteristics of each of the four elements of the metaverse. First, it is possible to obtain the convenience of augmenting the senses by using augmented reality, and secondly, it is possible to obtain the scalability and efficiency of reproducing the real space by using it as a mirror world element. Third, by using the lifelogging element, communication can be strengthened through the user's record and connection, and fourthly, through the virtual world element, roles and activities in the virtual world can be given to the user. Therefore, if digital cultural heritage is developed as a metaverse service in consideration of these factors, a more active and open experience environment can be provided to users.

This study attempted to explore what are the benefits that online game consumers seek in their on-line game consumption. Nowadays many on-line game consumers are extremely absorbed in the on-line game. The purpose of this study was to find the benefits that make people enjoy on-line games enthusiastically based on the Q methodology. Q methodology is a way to understand a person's structure of subjectivity. This study applied Q methodology to clarifying consumers' subjective evaluation of the on-line game benefit s. 28 Q questions were prepared through literature review, and were offered to 30 consumers. The subjects were divided into the four types seeking different benefits with on-line games: communication, enjoyment, achievement, and escapism. The results suggested that the benefits of on-line game are beyond the general characteristics of the game including human network or achievement in the on-line game community.

Devices have a lot of small breakdowns rather than big breakdowns. But it often wastes time and increases cost of maintenance, such as calling a service technician for small breakdowns. So, if we use remote control and monitoring service using Internet of Things, we can minimize the time period and cost for the maintenance. However, security is important because remote control and monitoring services contain personal information which when leaked, may be dangerous. There are many types of Internet based monitoring devices that are in use, but it is difficult to expect a high level of security because there are many cases in which the performance is minimal. Therefore, in this paper, we classify remote control and monitoring services based on Internet of Things type and derive encryption requirement for four types. We also compared and analyzed the lightweight cryptographic algorithms that can be expected to use high performance even on the Internet of Things. And it is derived that LED is used as a equipment management type, DESLX as a environment management type, CLEFIA as a healthcare management type and LEA as a security management type are the optimal lightweight cryptographic algorithms for each type.
