본 연구는 독립훼손지 중 아고산대에 위치한 지리산국립공원 세석평전과 노고단 복원식생지를 대상으로 현존식생 분석 및 식생분포 특성을 파악하여 중장기적인 모니터링 및 관리방안 수립을 위한 기초자료를 제공하고자 수행하였다. 현존식생 조사범위는 훼손지 일대 유역권분포 현황을 고려하여 설정하였으며, 세석평전 조사면적은 55,037㎡, 노고단 조사면적은 166,599㎡ 이었다. 세석평전은 초본층에 의한 식생피복도는 90% 이상 수준으로서 나지노출이 없었고, 관목층의 피복도가 60% 이상으로 안정화되어 있었다. 주요 출현수종은 구상나무, 사스래나무, 쇠물푸레나무, 철쭉, 털진달래, 붉은병꽃나무 등 식재수종과 자연적으로 이입한 자생수종이 생육하고 있었다. 노고단은 신갈나무, 호랑버들, 철쭉, 털진달래, 미역줄나무 등이 우점하는 관목식생지가 52%로 가장 넓게 분포하고 있었고, 전반적으로 식생활착 상태가 양호하였다. 노고단의 원식생은 신갈나무군락으로 추정되었고, 군부대철거지에는 귀화식물이 분포하고 있기 때문에 적극적인 관리가 필요하였다. 연구대상지는 장기적으로 주변 자연식생과 조화로운 식생경관으로 발달할 것으로 예측되었다. 향후 훼손지 복원모델은 인근 지역의 원식생을 고려하여 설정해야 할 것이지만, 복원 달성 목표는 실현가능한 수준의 목표를 설정해야 할 것이다. This study was conducted to provide basic data for mid-to long-term monitoring and establishment of management plans by analyzing the existing vegetation and identifying the vegetation distribution characteristics for the restored vegetation in Nogodan and Seseokpyeongjeon in Jirisan National Park located in the subalpine zone among the independent damaged areas. Actual vegetation survey range was established in consideration of the distribution of the watershed around the damaged area. The surveyed area of Seseokpyeongjeon was 55,037㎡, and the surveyed area of Nogodan was 166,599㎡. In Seseokpyeongjeon, the vegetation coverage by the herbaceous layer was almost 90% or more, there was no bare exposure, and the coverage of the shrub layer was stabilized at 60% or more. The main emerging tree species were planted species such as Abies koreana, Betula ermanii, Fraxinus sieboldiana, Rhododendron schlippenbachii, Rhododendron mucronulatum var. ciliatum, and Weigela florida as well as natively migrated native species. In Nogodan, the shrub vegetation dominated by Quercus mongolica, Salix caprea, Rhododendron schlippenbachii, Rhododendron mucronulatum var. ciliatum, and Tripterygium regelii was the most widely distributed with 52% of the area, and the overall diet was good. The native vegetation of Nogodan was presumed to be a cypress colony. Naturalized plants were distributed in the military base demolition site, so active management was required. The study site was predicted to develop into a vegetation landscape in harmony with the surrounding natural vegetation in the long term. In the future, the restoration model for damaged areas should be set in consideration of the native vegetation of the nearby area, but the goal to achieve restoration should be set at a feasible level.

2차원 그래픽을 3차원 그래픽으로 변환하기 위한 삼차원 그래픽 알고리즘들은 복잡하고 다양한 기법의 사용으로 인하여 대규모의 반복 연산이 요구되고, 이로 인하여 실시간 삼차원 그래픽의 처리가 어려운 경우가 많다. 본 논문은 삼차원 그래픽 처리와 관련된 여러 가지 알고리즘 중에서 Phong Shading 알고리즘의 병렬처리 방법과 고속 하드웨어 처리를 위한 삼차원 그래픽 가속기에 관한 것으로, Park's 다중접근 기억장치와 다수의 연산기로 구성된 SIMD처리기를 사용한 삼차원 그래픽 가속기 구조를 제안하고 있으며, 제안된 가속기 구조를 HDL을 사용한 시뮬레이션을 통해 본 논문에서 제안된 삼차원 그래픽 가속기에 의해 복잡한 알고리즘을 갖은 어떠한 삼차원 그래픽 알고리즘도 병렬 처리 알고리즘을 적용하여 SIMD 가속기에 의한 실시간 처리가 가능함을 보였다. There are many algorithms for 2D to 3D graphic conversion technology which have the high complexity and large scale of iterative computation. So in this paper propose parallel algorithm and high speed graphics accelerator architecture using Park's MAMS(Multiple Access Memory System) for Phong Shading, one of many 3D algorithms. The Proposed SIMD processor architecture is simulated by HDL and simulated and got 30 times faster result. It means any kinds of 3D algorithm can make parallel algorithm and accelerated by SIMD processor with Park's MAMS for real time processing.

60세 이상 노인들에서 CIDI가 치매와 비치매를 얼마나 잘 예측할 수 있는가를 알아보기 위해서 시행되었다. 방법: 어느 대학병원 정신과 환자들 중에서 DSM-IV상 치매 환자 86명과 60세 이상의 비치매 환자 129명이었다. 여러 변수들 중에서 교정 연령(실제 연령 -59), 교육 구간(무학,초등 교육, 중등교육, 고등교육), 그리고 CIDI 총점을 독립 변수로 하고, 치매 유무를 종속 변수로 하여 로지스틱 회귀 분석을 실시하였다. 결과: -2 log likelihood는 상수만 포함된 경우에는 289.395이었고, 교정 연령, 교육 구간, CIDI 성적 등의 독립 변수가 포함되면 102.773이었다(χ²=186.622, df=3, p=0.000), 적합도 통계는 156.798(χ²=6.5843,df=8, p=0.5821)이었다. 전박적 분류 일치율은 90.2%이었다. 세 독립 변수들의 통계값을 이용하여 로지스틱 회귀 방적식 y=7.5752 + 0.0940 * X₁+0.9820 * X₂-0.1811 * X₃(y=ln[π/(1-π)], X₁ :교정 연령, X₂: 교육 구간 X₃: CIDI 총점, π : 치매일 확률, 0.50 이상이면 치매, 미만이면 비치매)을 만들 수 있었다. 진단 예측에 영향을 끼치는 변수들 즉, 교정 연령, 교육 구간, 그리고 CIDI 총점의 □(95% C.I)는 각각 1.0985(1.0107 - 1.1940), 2.6699(1.4134 - 5.0436), 0.8344(0.7898- 0.8815)이었다. 결론: 회기분석 결과 CDIA는 치매 진단의 예측에 매우 유용한 인지기능 평가 도구임이 확인되었다. Objective: This study aimed at investigating the diagnostic predictability of Cognitive Impairment Diagnosing Instrument(CIDI) in diagnosing dementia of elderly people aged 60 years or more. Method: The subjects were 129 patients with other mental diseases than dementia whose ages were more than 60 years and 86 patients with dementia. Psychiatric diagnoses were made by according to the DSM-IV criteria. Converted age(chronological age minus 59) was employed for the statistical reason. The length of education was classified into 4 intervals : 1 for less than one year schooling, 2 for grade schooling, 3 for junior or senior high schooling and 4 for college or more schooling and each number espresses ordinal scale. The converted age, length of education expressed by one of 4 interval scores, and total CIDI score were independent variables while the diagnosis(dementia vs nondementia) was dependent variable in the logistic regression analysis. Results: -2 log likelihood was 102.773 when the lenght of education, converted age and total CIDI score were included while it was 289.395 when only the constant was included(χ²= 186.622, df=3, p=0.000). The goodness-of-fit statistic was 156.798(χ²=6.5843, df=8, p=0.5821), and the overall conocordance of diagnostic classification was 90.2%. The logistic regression equation for the diagnosis of dementia was generated as follows : y=7.5752 + 0.0940 * X₁+0.9820*X₂-0.1811*X₃(y=1n[π/(1-π)], X₁ : converted age, X₂: education intervals, X₃:total CIDI score, π : possibility of dementia, ≥0.50 indicating dementia and < 0.50 ndicating nondementia). The ebs(95% C.I.) for the converted age, education interval and total CIDI score were 1.0985(1.0107 - 1.1940), 2.6699(1.4134 - 5.0436), 0.8344(0.7898 - 0.8815), respectively. Conclusions: The CIDI could be considered as a useful diagnostic tool for dementia using the logistic regression analysis.

This study was conducted to analyze the relationships of social support, life satisfaction and depression that influences health of the elderly. We used a structured questionnaire in interviewing the elderly. The interviewees were composed of 200 persons in homes and 93 persons in institutions aged more than 60. And they were selected by systemic stratified random sampling. The data collecting period was from June 2 to August 10, 1988. The each level of social support, life satisfaction and depression was measured by social support scale, life satisfaction scale and self-rating depression scale. The data was analyzed by the SPSS-X computer program. The result of this study were as follows: 1. The level of social support of the elderly in home was higher than that of the institutionalized elderly (P<0.001). 2. The level of life satisfaction of the elderly in home was higher than that of the institutionalized elderly (P<0.001). 3. The level of depression of the elderly in home was lower than that of the institutionalized elderly P<0.05). 4. Hypothesis I; was accepted (r=0.545, P=0.000) “The higher the social support is, the higher the life satisfaction is”. 5. Hypothesis Ⅱ; was accepted (r=-0.513, P=0.000) “The higher the social support is, the lower the depression is”. 6. Hypothesis Ⅲ; was accepted (r=-0.620, P=0.000) “The higher the life satisfaction is, the lower the depression is”. It was revealed that the relationship between social support and life satisfaction was positively correlated. Each relationships between social support and depression and life satisfaction and depression was negatively correlated. Therefore, it can be concluded that this study provides nurses with the knowledge that social support is an important factor than can improve life satisfaction and at the same time reduce depression in the elderly.

The zinc titanate sorbents(ZTG40) were prepared and the tests for durability and attrition resistance were carried out to develop the highly effective desulfurization sorbents. In the attrition tests for ZTG40 the results showed that the attrition resistance was 94.08% and that the sulfur capacity was maintained above 15g S/100g sorbent throughout the 100-cycle test, its maximum being 23.05g S/100g sorbent. As compared to sorbents developed by the developed countries, ZTG40 showed superior performances. In the advanced countries 15g S/100g sorbent is a yardstick of excellency for the sulfur capacity of desulfurization sorbents. Therefore, ZTG40 developed in this study has the desirable physical and chemical properties for fluidized desulfurization of coal gases.
