Defects on apartment which is one of the major residential types in Korea have produced unexpected inconveniences to owners of apartments. If construction companies paid more careful attention to defect information management, a lot of flaws could be prevented. In this situation, this study attempted to seek improved defect information DB management system. First, research on defect information DB management system of large construction firms was conducted to confirm necessities of improved system. Following survey showed problems of current defect information DB management system and the need of improvement. The study came up with remedies expected to contribute to preventing faults.

Local government has constructed GIS DB for efficient business achievement and effective management of complex city facilities and has been developing and utilizing application systems, such as Underground Facility Management System Road Management System and so on. However, Facility Management System is providing functions for business, but not for GIS DB's maintenance. City facilities GIS DB managed by GIS technical expert collects basic figure and attribute information through survey and field investigation and is constructed via complex process, such as structurize editing etc. So it has been concerned that the update and confidence of CIS DB can be lower if a business man who does not have enough experiences about Facility Management System operates it by himself. Therefore, functions that enable business users to operate Facility Management System easily should be provided.

Diabetes is one of the serious chronic metabolic diseases caused by Westernized eating habits, and the goal of diabetes treatment is to keep blood glucose at a normal level and prevent diabetic complications. This study was designed to investigate the anti-diabetic effects of a mealworm (Tenebrio molitor larva) extract (MWE) on hyperglycemia in an animal model with type 2 diabetes. Diabetic C57BL/Ksj-db/db mice were divided into three groups: diabetic control, rosiglitazone, and MWE. The mice supplemented with MWE showed significantly lower blood levels of glucose and glycosylated hemoglobin when compared with the diabetic control mice. The homeostatic index of insulin resistance was significantly lower in mice supplemented with MWE than in diabetic control mice. MWE supplementation significantly stimulated the phosphorylation of insulin receptor substrate-1 and Akt, and activation of phosphatidylinositol 3-kinase in insulin signaling pathway of skeletal muscles. Eventually, MWE increased the expression of the plasma membrane glucose transporter 4 (GLUT4) via PI3K/Akt activation. These findings demonstrate that the increase in plasma membrane GLUT4 expression by MWE promoted the uptake of blood glucose into cells and relieved hyperglycemia in skeletal muscles of diabetic C57BL/Ksj-db/db mice. Therefore, mealworms are expected to prove useful for the prevention and treatment of diabetes, and further studies are needed to improve type 2 diabetes in the future.

Large corpus-based concatenating Text-to-Speech (TTS) systems can generate natural synthetic speech without additional signal processing. Because the improvements in the natualness, personality, speaking style, emotions of synthetic speech need the increase of the size of speech DB, it is necessary to prune the redundant speech segments in a large speech segment DB. In this paper, we propose a new method to construct a segmental speech DB for the Korean TTS system based on a clustering algorithm to downsize the segmental speech DB. For the performance test, the synthetic speech was generated using the Korean TTS system which consists of the language processing module, prosody processing module, segment selection module, speech concatenation module, and segmental speech DB. And MOS test was executed with the a set of synthetic speech generated with 4 different segmental speech DBs. We constructed 4 different segmental speech DB by combining CM1(or CM2) tree clustering method and full DB (or reduced DB). Experimental results show that the proposed method can reduce the size of speech DB by 23% and get high MOS in the perception test. Therefore the proposed method can be applied to make a small sized TTS.

Quite a while ago, Organizations which have slope DB system was running slope of management in several. Frequently, Slope failure was happened by abnormal weather and limit of valuation system at the managed slope. Analysis of other organization slope DB systems is very important that slope DB system maintains same regions on geology. In Korea, slope DB system was running at KEC(Korea Expressway Corporation), Korail(Korea Railroad), and KIGAM(Korea Institute of Geoscience and Mineral Resources). We research theirs DB constructing. For reviewed slope DB system of other country, we searched NLIC(Natural Landslide Information Center)'s DB system in U.S.A., GEO's LPM(landslide Prevention Measures) program in Hongkong, DPRI' ILC(International Consortium on Landslides) program in Japan, and AGSO(Australian Geological Survey Organization)'s NGVUC program in Australia.

The government is spending a large amount of budget to establish NGIS due to the importance of geospatial information. This paper deals with the study of schema mapping technique which can efficiently establish military topographic DB forest layer using digital forest map and other existing geospatial DB. In order to accomplish this 1) each schema of these types of DB was analyzed then, 2) mapping table which connects related attributes was created and finally, 3) military topographical DB forest layer of the area of interest was efficiently established. This research was able to display solutions that resolved compatibility issues between existing geospatial DB of these types, established by the schema mapping techniques described in this research.

The purpose of this study is to seek how to effectively acquire a full-text using LHI(Loca1 Holdings Information) when we search bibliographic DB. For this study, the pre-investigation of LHI within Online and CD-ROM DB was made using local and overseas literature. The questionary survey was made of librarians and users who have used CD-ROM. The finding of this study is that LHI is not very widely used in libraries, thus more study on ,LHI within Online and CD-ROM DB is required to get high quality information service.

본 논문에서는 ETRI 의 음성정보연구센터에서 추진하고 있는 공통 음성 DB 구축을 위한 발성목록의 설계 방법 및 그 내용에 대해 기술한다. 이 공통 음성 DB는 국내의 학계와 연구기관, 산업체에 배포하여 음성기술개발에 활용될 수 있도록 하려는 목적으로 구축되는 대규모의 DB인 만큼, 다양한 활용 분야를 고려하여 설계되었다. 따라서 내용적으로 중립성을 유지하면서도 효율성과 기능성을 고려하여 설계한 것이 이번 발성목록 설계의 특징이라고 할 수 있다. 이번 발성목록은 크게 음성 인식용 DB 와 낭독체 합성용 DB, 대화체 합성용 DB, 그리고 화자 인식용 DB 분야로 나뉘어진다. 이 논문에서는 각 DB 종류별로 발성 목록의 내용과 작성 방법, 그리고 이들을 작성함에 있어서 고려된 사항 등을 기술한다.

본 논문에서는 5.1 채널 입체 음향 오디오 신호를 2채널의 헤드폰으로 재생하기 위해 사용하는 HRTF(Head-related transfer funcion) DB를 다룬다. 다양한 HRTF DB의 사례를 분석하고, 이를 통해서 더 나은 HRTF DB를 설계 한다. 기존의 HRTF DB에 Audio Meta data를 이용하여 파일의 정보를 저장하고, 이를 DB에 저장함으로써 Meta data를 비교 검색하고 저장함으로써 편의성을 높인다. 또한 기존의 HRTF DB들이 오래 되고 현재의 시스템에 맞지 않기 때문에 이를 현재의 시스템에 맞게 Converting하고 UI를 3D로 구현함으로써 UX를 높이고 직관성을 개선함으로써 사용자 접근성을 높인다. 이를 통해서 HRTF DB의 범용성을 개선하고 관련 연구에 효율적으로 사용할 수 있게 될 것이다.
