  • 한반도의 심부 전기구조를 조사하기 위해서 극심부 전자탐사 중 하나인 지자기 수직탐사(GDS; Geomagnetic Depth Sounding)를 수행하였다. 본 연구에서는 한반도 동남부에서 추가적으로 획득된 5개의 GDS 탐사 자료와 기존의 12개 측점의 탐사 자료를 통합하여 해석하였다. 또한 한반도 및 주변 해양의 영향을 정량적으로 평가하기 위하여 3차원 MT 모델링이 수행되었다. 관측된 실수 유도 지시자는 주변 해양의 영향만으로 설명되지 않았으며, 이 차이를 설명할 수 있는 2개의 전도성 구조를 제시하였다. 첫 번째는 Quiling-Dabie-sulu 대륙 충돌대의 연장성이라 생각되는 임진강 벨트이며, YIN과 ICHN에서 그 영향을 명확히 확인할 수 있었다. 두 번째는 한반도 남해안과 큐슈 섬 사이에 존재할 것으로 추정되는 맨틀 용승에 의한 고전도성층(HCL; Highly Conductive Layer)로서, 주로 한반도 동남부에 위치하는 KZU, KMT101, 107에서 그 존재를 확인할 수 있었다.

  • 본 연구는 지식경영시스템 구축의 대안으로, 그룹의사결정지원시스템(GDSS : Group Decision Support System)의 활용 방안을 제시하였다. GDSS는 구성원들의 사회적 의사소통과 기술적 의사소통 모두를 지원할 수 있는 형태로 설계되고 실행되어야만 지식집약 조직의 달성과 유지에 긍정적인 영향을 미칠 수 있다. 기존 GDSS에 관한 문헌에서 제공되는 세 가지 수준의 GDSS와 지식변환과정 및 집단 구성원의 의사소통 유형과의 관계에 대한 이해를 바탕으로, GDSS에 새롭게 추가되어야 하는 특성 및 활용 가능한 기술을 제시하였으며, 지식관리 기반기술 중 조직에 구축된 KMS에 적용되지 못하고 있던 지식관리 기반기술의 GDSS를 통한 활용 방안도 발견할 수 있었다.

  • A GDS (Geomagnetic Depth Sounding) method, one of extremely low-frequency EM methods, has been carried out to examine conductivity anomalies in and around the Korean Peninsula. In this study, new GDS data acquired at the five sites in south-eastern area of the peninsula were incorporated into the previous GDS data. In order to quantitatively interpret observed induction arrows, the 3-D MT modeling considering the surrounding seas of the Korean Peninsula has been performed to evaluate sea effect at each GDS site. The modeling results revealed that the observed real induction arrows were not explained by solely sea effects, consequently two conductive structures that are responsible for the discrepancies between observed and calculated induction arrows were proposed. The first one is the Imjingang Belt, which is thought as an extension of Quiling-Dabie-sulu continental collision belt. The effects of the Imjingang Belt clearly appear at the site YIN and ICHN. The second one is the HCL (Highly Conductive Layer), which is considered as a conductive anomaly by mantle upwelling produced in back-basin region. The effects of the HCL are seen at the site KZU, KMT101, and KMT 107 in the south-eastern region of the Korean Peninsula.

  • The objectives of this study were to develop the therapeutic recreation programs for relieving depressive symptoms of the elderly and to verify the effect on their psychological condition. The key elements of these programs, which consisted of 9 sessions. were aerobic exercises, group dynamics. and making fun. These programs were developed through a multidisciplinary approach with social workers and the faculties of preventive medicine. The social workers gave these programs to fifteen elderly people at the community center, so called noinjung, for 9 weeks. Before intervention of this program for the experimental group, the baseline was measured by GDS(geriatric depression scale). After intervention for 9 weeks, GDS as an outcome was measured to evaluate the effects of the program. This data was analyzed by $X^2$-test and Wilcoxon signed rank test. and the results were as follows: 1. Based upon the cutting point(GDS = 5) which could distinguish between depression group and normal group, the number for the normal group increased, while the number for the depression group decreased slightly after intervention with the therapeutic recreation programs, however, there was no significant change(p〉0.05). 2. The score of GDS decreased significantly after intervention with the therapeutic recreation programs(p〈0.05). 3. The scores of GDS decreased in widow(or) group and in female group compared to those of the married group and the male group, respectively(p〈0. 05). 4. The score of GDS increased in groups with similar labor and emotional support compared to those of groups with sufficient or less support, respectively(p〈0.05), These findings indicate that the therapeutic recreation programs might be effective for relieving depressive symptoms of the elderly. It is, therefore, suggested that this program be modified and standardized through review of the intervening process, experimental results, and responses of clients for appling in other noinjungs.

  • Purpose. The purpose of this study was to determine the effect of cognitive based programs on cognitive functions in elderly people. Methods. The participants included a group of 9 elderly people in Changwon, from the period of May 2016 to July 2016. The test tools used were MMES-K. SADL. and GDS. The statistics used was the 20.0 version. Results. According to the results of this study, the MMSE, GDS mean scores improved after implentation of the program, but no significant improvement was shown with SADL. The MMSE of the correlation coefficient was 0.785, and the GDS of the correlation coefficient was 0.916. Both of these scores were significant in their correlation. Conclusion. In conclusion, cognitive based programs were effective among mildly cognitive-impaired elderly people, and that suitable programs must be developed on a case by case basis.

  • This paper presents an application of rule based expert system to GDS. Expert system is a computer-based system that uses knowledge, facts, and reasoning techniques to solve problems that normally require the abilities of human experts. Expert system can be classified as synthesis expert system, classification expert system or combination of these. The Expert system of GDS belongs to the synthesis type of expert system. GDS is a graphic design environment that automates complex and time consuming processes in the design phase of the grating production. There are methodical procedures in the design phase of gratings and each process needs the know-how of a skillful designer. User has to know...

  • Background: As social problems due to the acceleration of the aging era and the increase in the elderly population are becoming serious, virtual reality (VR)-based healthcare is emerging as an approach for preventing and managing health issues. Objects: This study used validity and reliability analyses to examine the clinical efficacy that is, the clinical value and usability of a novel VR cognitive evaluation system index that we developed. Methods: We developed a VR cognitive evaluation system based on motion recognition analysis evaluation for individuals aged 65 to 85. After conducting the Korean version of the Mini-Mental State Exam (K-MMSE) cognitive evaluation, the evaluation score was verified through correlation analysis in the VR cognitive evaluation system. To verify the construct validity of the two groups, the Global Deterioration Scale (GDS) grades were categorized into a normal cognitive group (GDS grade 1) and a cognitive impairment group (GDS grades 2 and 3). The data were measured twice to determine the reliability between the two measurements and assess the stability and clinical value of the evaluation system. Results: Our evaluation system had a high correlation of 0.85 with the widely used K-MMSE cognitive evaluation. The system had strong criterion-related validity at the 95% confidence interval. Compared to the average score of GDS grade 1 in the VR cognitive evaluation system, the average score of GDS grades 2 and 3 in the VR cognitive evaluation system was statistically significantly lower while also having strong construct validity at the 95% confidence interval. To measure the reliability of the VR cognitive evaluation system, tests-retests were conducted using the intraclass correlation coefficient (3,1), which equaled 0.923 and was statistically significant. Conclusion: The VR cognitive evaluation system we developed is a valid and reliable clinical tool to distinguish between normal cognitive status and mild cognitive impairment.

  • We have been aware fer some time. that it is becoming harder to develop ASIC only, using the vendor wire model for the current top-down/bottom-up process. Because VDSM has a much bigger wired delay than cell delay, it is also difficult to reduce development time, as well as time-to-market, while developing several million gate ASIC's. The same is true for high frequency ASIC's with VDSM (which have larger wire delay versus cell delay). Therefore, a solution called “RTS-GDS”, using physical constraints fur SOC with timing met, is being actively discussed. This paper suggests a methodology for SOC development by utilizing a top down flow via CWLM along with discussing potential problems. This paper also provides a design flow, including physical synthesis, DFT, floor plan and CWLM, all of which are relevant to proper SOC development.
