최근 인터넷의 급속한 성장과 초고속 통신망의 구축으로 인하여 다양한 멀티미디어 서비스들이 제공되고 있다. 그러나 현재 대부분의 멀티미디어 서비스들은 클라이언트/서버 모델을 기반으로 구축되어 있기 때문에, 중앙 서버로의 과도한 부하가 집중되어 전체적인 네트워크 속도 저하를 발생시키는 문제점을 가지고 있다. 본 논문에서는 이러한 문제점을 해결하기 위해 순수 P2P 환경으로 구축된 멀티미디어 서비스 환경에서의 자원 검색 기법을 제안한다. 제안 기법은 자율성과 이동성을 지닌 이동 에이전트를 기반으로 자원의 검색을 수행하여, 기존의 순수 P2P 환경에서의 검색 기법에서 네트워크의 불안정시 검색 결과가 유실되는 문제점을 해결한다. 제안 기법은 이동 에이전트를 사용하기 때문에 이 기종의 시스템간 서비스를 제공할 수 있는 장점을 가지고 있고, 동일 자원과 최근 요청 자원에 대한 위치 정보를 유지하므로 기존 순수 P2P 환경에서의 검색 속도보다 빠른 응답 속도를 가지는 장점을 가진다. Recently the rapid growth of Internet and the construction of high speed networks make many kinds of multimedia services possible. But most of current multimedia services are designed being by client/server model, which incurs high load of central server. In order to solve this problem, we propose a peer-to-peer network-based discovery mechanism for multimedia services. In the proposed scheme, mobile agents that have autonomy and mobility are used to search the location of resources. Use of mobile agents can solve the loss problem of the search result that occurs when the network is unsettled in pure peer-to-peer network. It also supports interoperability in heterogeneous system environments. In the proposed scheme, each host maintains the location information of resources which are locally requested or recently requested by other hosts. So, the proposed scheme has faster response time than the pre-existing mechanisms in pure peer-to-peer network environments.

Purpose. The purpose of this study was to muscle properties analysis of SCM(sternocleidomastoid) Muscle according to posture type when using smartphone. Methods. This study was conducted on 73 college students who are using smartphone. Subjects were analyzed myotonPRO to confirm, prone posture group, stand posture group, drop head above $45^{\circ}$in sit posture on a chair group and drop head below $45^{\circ}$in sit posture on a chair group were measured SCM muscle. The myotonPRO were measured one measurer, total 3 times. Comparative analysis of the each groups were investigated of SCM muscle properties. Results. We found that Frequency, Stiffness, Creep and Relaxation were appeared difference in each posture. F index was increased at drop head below $45^{\circ}$group than stand posture group. S index was increased at drop head above $45^{\circ}$group than prone posture group.

위도상사화(Lycoris uydoensis M. Kim)의 효율적인 기내 급속 대량 증식체계를 확립시키고자 잎과 인편을 배양하였다. 5℃에서 60일간 저온 처리한 모구를 구고를 중심으로 상부, 중부 및 하부로 구분하여 0.1 mg·L-1 2,4-D와 1.0 mg·L-1 BA, 0.5 mg·L-1 NAA와 1.0 mg·L-1 BA 또는 3.0mg·L-1 IBA와 3.0 mg·L-1 BA 혼용처리된 MS 배지에 배양한 결과 식물생장조절물질과는 관계없이 디스크가 부착된 인편의 하부가 캘러스 및 자구 형성에 가장 효과적인 부위였다. 캘러스는 잎절편이나 인편조직에서 쉽게 형성되었으나 소자구 및 신초는 인편에서만 형성되어 기내번식에 적합한 절편체는 인편이었다. 자구 형성 및 신초분화는 배지내 첨가된 식물생장조절물질에 따라 치상체에서 직접 자구를 형성하거나 캘러스를 통해 식물체로 분화되는 2가지 경로로 형성되었는데 디스크가 부착된 인편을 0.1 mg·L-1 2,4-D와 1.0 mg·L-1 BA, 0.5 mg·L-1 NAA와 1.0 mg·L-1 BA 또는 3.0 mg·L-1 IBA와 3.0 mg·L-1 BA 혼용처리된 MS 배지에 배양하여 30일 이내에 60%-100%까지 유도하였다. 다량의 자구형성 및 유지는 MS배지에 0.1 mg·L-1 2,4-D와 1.0 mg·L-1 BA가 혼용되거나 또는 3.0 mg·L-1 IBA와 3.0mg·L-1 BA 혼용처리 되었을 때 0.5 mg·L-1 NAA와 1.0mg·L-1 BA 혼용처리 되었을 때 보다 효과적이었다. 6% sucrose는 자구형성 및 비대를 촉진시켰으며 특히 3.0 mg·L-1 IBA와 3.0 mg·L-1 BA 혼용처리배지에 6% sucrose를 첨가시키므로 0.1 mg·L-1 2,4-D와 1.0 mg·L-1 BA가 혼용 배지보다 구의 비대가 1-2배 증가하였다. 인편유래 캘러스로부터 기관분화 또는 인편에서 직접 분화된 자구에서 성공적으로 식물체가 재분화되었다. This study was conducted to establish an effective in vitro mass propagation system using leaf and bulb scale explant sources of Lycoris uydoensis M. Kim. For the bulb scale culture, the bulbs treated at 5℃ for 60 days were dissected into three parts according to bulb height (upper, middle, and bottom), and allowed for a culture on the MS medium with 0.1 mg ? L-1 2,4-D plus 1.0 mg ? L-1 BA, 0.5 mg ? L-1 NAA plus 1.0 mg ? L-1 BA, and 3.0 mg ? L-1 IBA plus 3.0 mg ? L-1 BA. Regardless of plant hormone treatments, the bottom part of the bulb including the disk proved to be most effective in forming the callus and bulblets. Callus was readily produced on the young leaf segment and bulb scale tissues, whereas, bulblets and shoots were formed only on bulb scale explants. Bulb scales with disk appeared to the best optimal explant for in vitro propagation. Two distinct pathways, either organogenesis through callus or direct bulblet formation, could be recognized in bulb scale culture. Bulblet formation and shoot organogenesis from the bulb scales with disk were effectively induced up to the 60%~100% on the MS medium supplemented with 0.1 mg ? L-1 2,4-D plus 1.0 mg ? L-1 BA, 0.5 mg ? L-1 NAA plus 1.0 mg ? L-1 BA, and 3.0 mg ? L-1 IBA와 3.0 mg ? L-1 BA within 30 days of culture. On MS media supplemented with 0.1 mg ? L-1 2,4-D plus 1.0 mg ? L-1 BA or 3.0 mg ? L-1 IBA와 3.0 mg ? L-1 BA were more effective than 0.5 mg ? L-1 NAA plus 1.0 mg ? L-1 BA for induced and maintained a large number of bulblets. Six percent of sucrose enhanced bulblet formation and expanded the bulblets. Especially, adding 6% of sucrose on MS media supplemented with 3.0 mg ? L-1 IBA와 3.0 mg ? L-1 BA was one or two times of bulblets expanted than on MS mediun with 0.1 mg ? L-1 2,4-D plus 1.0 mg ? L-1 BA plus 6% of sucrose. Plantlet regeneration was successfully achieved from bulb scale-derived callus, via shoot bud induction or direct bulblet formation.

The purpose of this study is to examine the differences in appearance management behaviors and demographic variables among groups classified by the appearance management motives. The questionaries are administerd to 493 female and male adults above 20 years old in Seoul, Kyeonggi-do, Daegu and Kyungpook regions. For analysis of data from 478 respondents, descriptive statistics, factor analysis, cluster analysis, Cronbach's ${\alpha}$, ANOVA, Duncan test and ${\chi}^2$ test were applied. We show the following results: First, factor analysis for appearance management motives extracted three factors such as self-development, emphasis on the trendy appearance, and sexual appealing motive. Factor analysis for appearance management behaviors extracted four factors such as weight training, surgery/skin care, hair care and clothing selection. Second, three groups of the appearance management motives were classified into such as the social self-management type, the sexual appealing self-management type, the passive appearance management type. The social self-management groups are more interested in self-development, emphasis on the trendy appearance, and sexual appealing motive. And they are also more involved in appearance management behaviors: clothing selection is the most pursuing appearance management behavior. Third, among the demographic variables, the single and female in 20s and 30s with higher level of education belonged to the social self-management group. In this contribution, we find significant differences in the appearance management behavior and demographic variables classified by the appearance management motives.

전자잡지는 원고 작성부터 편집, 제작 등 전 과정에 이르기 까지 컴퓨터 활용은 물론 CD-ROM이나 인터넷을 이용, 전통 인쇄방식 없이도 독자에게 전달되는 단계에 접어 들었다. 컴퓨터와 인터넷, 그리고 디지털혁명과 뉴테크놀로지는 잡지 형태를 현격히 변화시키고 있는 것이다. 앞으로 정보기술을 이용한 전자잡지의 발전은 더욱 증대될 것이다. 따라서 전자잡지 분야에서는 이러한 신기술의 발전에 대해 더욱 많은 관심과 끊임없는 실험정신을 가지고 멀티미디어 시대를 대비해 나가야 할 것이다.

The present study was conducted to investigate the structural changes in rat cornea. Sixty eyes from one-day-old uneyed rats, fourty eyes from 4-weeks-old rats, and foully eyes from 10-weeks-old adult rats were used. With the increase of age, the epithelial layer was thickened by the addition of new successive cellular layers. Then, the new-born rat's epithelial cells formed a pentagonal shape, and the quality of decidual cells showed a high electron-density, although the boundary between cells was distinctive. The newly produced cells showed a low electron-density so that there was the distinctive difference between light and darkness. In Bowman's layer, collagen fibrils demonstrate a regularly arranged structure along with the age. In stroma's layer, the density of keratocytes was decreased and thereby Progressively flattened during the development. The collagenous layer of the adult rats was more distinctive than that of the new-born rats in a form of parallel alignment running vertically and horizontally.
