Web personalization has focused on extracting web pages interesting to users, to help users searching wanted information efficiently on the web. One of the main methods to achieve this is by using queries, links and users' preferred words in the pages. In this study, we surveyed from the web users the features of pages that are considered important to themselves in selecting web pages. The survey results showed that the content of the pages is the most important. However, images and readability of the page are rated as high as the content for some users. Based on this result, we present a method for maintaining relative weights of major page features differently in the profile for each user, which is used for personalizing web search results. Performance of the proposed personalization method is analyzed to prove its superiority such that it yields as much as 1.5 times higher rate than the system utilizing both queries and preferred words and about 2.3 times higher rate than a generic search engine.

Pefloxacine(PFX)은 기존 quinolone계 항균제의 단점을 보완한 fluoroquinolone계열의 합성 항균제로서 그람양성균과 그람음성균에 대해서도 살균효과가 뛰어날 뿐 아니라 내성균 출현 가능성이 비교적 낮은 장점이 있는 항균제로 보고되고 있다. 이러한 약리학적 특성 때문에 우리 나라에서도 양식어류 세균성 질병 치료제로 최근 사용량이 증가하고 있으나 현재까지도 어류를 대상으로 한 체내잔류 PFX의 정량분석방범과 PFX의 흡수, 분포, 해설 등 실제 약제 사용방법 설정에 필수적인 임상동태에 관해서는 연구가 되어 있지 않은 실정이다. 따라서 본 연구는 양식어류에 대한 PFX의 효과적인 사용방법을 확립하기 위하여 고속액체크로마토그라피(HPLC)를 사용하여 실험조건의 특이성 등을 검토하여 어체내 잔류 PFX의 최적 분석조건을 설정하였다. 그리고 주요 양식어류를 대상으로 PFX를 경구 투여한 후 시간경과에 따라 혈액을 채취하여 혈종에서의 약물동태학적 Parameter를 조사하였다.

The Q&A board is widely used as a means of communicating service enquiries, and the need for efficient management of the enquiry system has risen because certain questions are being repeatedly and frequently registered. This study aims to construct a student-centered FAQ, centered on the unstructured data posted on the university homepage's Q&A board. We extracted major keywords from 690 postings registered in the recent 3 years, and conducted the semantic network analysis to find the relationship between the keywords and the centrality analysis in order to carry out network visualization. The most central keywords found through the analysis, in order of centrality, were application, curriculum, credit point, completion, graduation, approval, period, major, portal, department. Also, the major keywords were classified into 8 groups of course, register, student life, scholarship, library, dormitory, IT and commute. If the most frequent questions are organized into these areas to form the FAQ, based on the results above, it is expected to contribute to user convenience and the efficiency of administration by simplifying the service enquiry process for repeated questions, as well as enabling smooth two-way communication among the members of the university.

Multicultural family members have difficulty in educating their children due to language differences. In order to solve these difficulties, it is necessary to provide smart translation services that enable them easily and quickly access real-life vocabularies. However, the current automatic translation technology is being developed in dominant languages such as English, Chinese, and Japanese. There are also limitations to translating special-purpose terms such as documents of schools and instructions of public institutions. In this study, we propose a real-time automatic word translation service for multicultural family members who understand beginner level Korean. The service automatically analyzes the semantics of each word in the Korean sentences and provides a word-by-word translation. This study includes semantic analysis research for Korean language, building multilingual translation knowledge, and fusion study of language education. We evaluated the word translation service for migrant women from Vietnam and Japan and obtained meaningful evaluation results.

This study aims to investigate Korean fashion-related research trends and knowledge structures on digital transformation through information-based approaches. Accordingly, we first identified the current status of the relevant research in Korean academic literature by year and journal; subsequently, we derived key research topics through network analysis, and then analyzed major research trends and knowledge structures by time. From 2010 to 2020, we collected 159 studies published on Korean academic platforms, cleansed data through Python 3.7, and measured centrality and network implementation through NodeXL 1.0.1. The results are as follows: first, related research has been actively conducted since 2016, mainly concentrated in clothing and art areas. Second, the online platform, AR/VR, appeared as the most frequently mentioned topic, and consumer psychological analysis, marketing strategy suggestion, and case analysis were used as the main research methods. Through clustering, major research contents for each sub-major of clothing were derived. Third, major subject by period was considered, which has, over time, changed from consumer-centered research to strategy suggestion, and design development research of platforms or services. This study contributes to enhancing insight into the fashion field on digital transformation, and can be used as a basic research to design research on related topics.

People who use SNS publish their diverse ideas on SNS every day. The data posted on the SNS contains many people's thoughts and opinions. In particular, popular keywords served on Twitter compile the number of frequently appearing words in user posts and rank them. However, this method is sensitive to unnecessary data simply by listing duplicate words. The proposed method determines the ranking based on the topic of the word using the relationship diagram between words, so that the influence of unnecessary data is less and the main word can be stably extracted. For the performance comparison in terms of the descending keyword rank and the ratios of meaningless keywords among high rank 20 keywords, we make a comparison between the proposed scheme which is based on morphological analysis and PageRank, and the existing scheme which is based on the number of appearances. As a result, the proposed scheme and the existing scheme have included 55% and 70% of meaningless keywords among high rank 20 keywords, respectively, where the proposed scheme is improved about 15% compared with the existing scheme.

The objective of this study is to critically examine the result and the quality of urban park design as infrastructure by analyzing the landscape architectural design competition for Cheongna New City, which was organized by the Korea Land Corporation. This paper is meaningful in that it broadly examines several recent design competitions for urban parks, thereby discussing what the future urban park should be. This study explores the existing analysis methods of design competitions in order to establish a comprehensive method of analysis for the Cheongna competition. Through reinterpreting the concept of the urban park as infrastructure and the design strategies of landscape urbanism, nine key words and a framework for the analysis of urban park design are established. By analyzing the guidelines for the competition, five key words; networking, site, ecology, scale, and infrastructure have been selected and are used as the framework of analysis for the competition. The analysis of the contestants of the competition based on the proposed analysis method leads to a few implications for urban park design as infrastructure: networking and scale from the perspective of the development site; the creation of a sense of place and symbolism in creating the urban image; planning for an ecological urban environment; focus on the significance of the urban park as infrastructure. These implications are highlighted and discussed by the contestants through a variety of experiments. These ideas, however, are provided as a simple configuration of shapes and conceptual explanations and fail to be developed into synthetic, practical strategies.

This paper presents an echo-hydraulic experimental approach to assessment of ascending capacity of migratory fish in a baffled fishway. Sweetfish, Plecoglossus altivelis, trout, Oncorhynchus mykiss, are used in these experiments. Ascending environment of the migratory fish in rivers is analyzed through the results of taco-hydraulic experiments. Important factors affecting the ascending capacity of migratory fish in baffled fishways are the discharge and slope of fishways and the fall height between the fishway entrance and the river bed. In these fishways the migratory capacity of sweetfish for a given fishway discharge is mainly affected by fishway slope, whereas the ascending capacity of trout for a given fishway slope was influenced by the change of fishway discharge. Loss of ascending properties of landlocked salmon, Oncorhynchus masou var ishikawai, was confirmed by these experiments. An ascending hydraulic criteria of the baffled fishway is defined by means of dimensionless factor F$_{f}$ and falling head H$_{f}$. Ascending capacity of migratory fish in existing baffled fishways in river of eastern coastal region is poor because the slope of fishways is verb steep.eep.
