Employing in-depth interview, this study sought to explore the meaning of game play among those adolescent game addicts. Recent evolution of game text and rapid diffusion of smart media contributed to their addictive game use. Stronger relationship-building with their peer group through game play was also more important for them. In addition, alienation from family, school and society apparently led those adolescents to evaluate the virtual experience to be more valuable and meaningful. Lack of proper parental mediation and intervention from the school authority caused them to spend more time in the virtual world. Without understanding the complex social context surrounding the adolescents, a systematic approach to attenuate the problem of game addiction is hardly attainable.

The manufacture of vinegar provides a means of utilizing the juices of many fruits and various kinds of cereals as well as of starchy vegetables. However, no successful attempt has been made to utilize the glutinous rice powder, which is discussed from the Mi Gwa (made of glutinous rice) making, for the manufacture of vinegar. After alcoholic fermentation of the glutinous rice power, it was devided to ferment the liquor to vinegar and to examine factors affecting this fermentation. A laboratory typed vinegar generator was used to convert the alcohol in fermented liquor to acetic acid. Recycling of the fermented liquor through the generator was found essential in this process. Among many strains of Acetobacter cultures used, which was selected from ordinary home made vinegar from all over the Korea, Acetobacter No. Aa-97 proved more efficient for this fermentation. Addition of 1％ phosphate (K$_2$HPO$_4$) and 20％ apple cider vinegar. to the fermented liquor increased both the rate and efficiency of acetic acid fermentation.

Traditionally, the construction industry field is one of the typical fields using facet analysis method. Internationally the facet analysis method is applied to the classification scheme "Uniclass" or thesaurus "Construction Industry Thesaurus(CIT)". In the case of Korea, the facet analysis method is being used in classification scheme "Construction Industry Classification System" but it is difficult to find studies on facet analysis method in thesaurus or building case study. This study aims to establish facet types by introducing building of thesaurus for information retrieval in construction field using facet analysis method and to suggest building plan of thesaurus in construction field using facet analysis method. In this paper, We establish the 11 top facets(agent/patient, artifacts, abstract, material, parts/component, works, attribute, media, process, space, time) and the 13 subfacet as rudimental facets and suggest building plan according to thesaurus building procedure which is suggested by International Standard(ISO 25964-1). The result of this study is expected to apply to facet based thesaurus. And it is also expected to reuse in Taxonomy or Ontology etc. and to use in interoperability with the classification scheme of Construction filed.

Abandoned channel is vestiges of running in the past. Abandoned channels have been formed mostly by artificial river maintenance through channel straightening in Korea. Managed properly, these now abandoned channels can provide habitat for wildlife, maintain biodiversity of aquatic life, security against flooding and recreation area for human. However, because the areas are officially classified as abandoned, the channels is collapsing and decaying from years of neglect. This study suggested functional assessment for wetland-type abandoned channel in order to provide appropriate management and investment. For this reason, The study will examine and evaluate these channels with regard to the following four major criteria (Natureless, Habitat, Water-friendliness and Water quality) and 21 indices. Consequently, abandoned channel in two Nakdong river sites, site 1 was needed for protection or improvement in the medium to longer term, while site 2 was in good condition. This evaluation method will be helpful to manage wetland-type abandoned channel in Korea and will be able to use National River Health Program.

In content-based image retrieval, the query is an image itself and the retrieval process is the process that seeking the similar images to the given query image. In this way of retrieval, the user has to know the basic physical features of target images that he wants to retrieve. But it has some restriction because to retrieve the target image he has to know the basic physical feature space such as color, texture, shape and spatial relationship. In this paper, we propose an emotion-based retrieval system. It uses the emotion that color images have. It is different from past emotion-based image retrieval in point of view that it uses relevance feedback to estimate the users intend and it is easily combined with past content-based image retrieval system. To test the performance of our proposed system, we use MPEG-7 color descriptor and emotion language such as "warm", "clean", "bright" and "delight" We test about 1500 wallpaper images and get successful result.lpaper images and get successful result.

A controlled group is closed compared to other organizations, which hinders collection of data and accurate analysis, so that it is hard to evaluate a controlled group's power structure and predict future changes using usual analytical methods including sociological approach. Analyzing a controlled group using SNA can allow for evaluation of inner power structure by revealing the relationships between members and identifying members with central roles given limited data. In this study, in order to evaluate changes in power structure, time-sequential SNA research was conducted by analyzing eigenvector centrality, which reflects individual influence and reveals the overall power structure. The result showed an improvement in accuracy compared to other centralities that contain individual degree or closeness, and made it possible to presume structural changes such as promotion or purge of a member.
