목적 : 본 연구는 대전지역 노인들의 일상생활동작 수행수준과 삶의 질에 관련된 요소를 측정하여 노인들의 일상생활동작 수준 및 삶의 질에 따른 일상생활동작 수행의 차이에 대해 알아보고자 시도되었다. 연구방법 : 연구 대상은 대전광역시에 거주하는 65세 이상의 재가 노인 500명으로 하였다. 본 연구에서 사용된 설문지는 일반적인 특성 및 일상생활동작 능력 평가도구인 Barthel Index, Frenchy Activities Index와 SF-12에서 발췌한 삶의 질 관련 요소들로 구성되었으며, 일대일 면접조사를 통해 수집되었다. 결과 : 대전 지역 노인들의 일상생활동작 수행점수는 평균 96.05(표준편차 11.04)이었으며, 노인의 결혼 상태, 가족구성, 자녀유무, 직업유무에 따라 기본적 일상생활동작수행의 차이가 있었다(p<0.05). 수단적 일상생활동작 수행점수는 평균 18.41(표준편차 10.28)로 노인의 성별, 연령, 교육 수준, 가족구성, 자녀유무, 직업유무에 따라 수단적 일상생활동작 수행의 차이가 있었다(p<0.05). 노인의 주관적 건강상태 및 생활전반에 대한 만족도에 따른 기본적 일상생활동작 수행수준과 수단적 일상생활동작 수행은 그룹 간 유의한 차이가 있는 것으로 나타났다(p<0.05). 결론 : 본 연구결과를 통해 대전 지역노인들의 기본적인 일상생활동작 수행의 수준과 수단적 일상생활동작 수행의 수준을 알 수 있었고, 주관적 건강상태나, 생활만족도와 같은 삶의 질에 관련된 요소와 일상생활동작 수행수준 간에 관련이 있음을 알 수 있었다. 앞으로 노인들이 건강하게 살 수 있도록 삶의 질을 높이기 위해서는 일상생활동작 수행수준을 높일 수 있는 작업치료사의 역할이 요구되며, 노인들의 의존적인 문제를 보완하고 능동적이며 긍정적인 삶을 유지할 수 있는 중재 방안이 마련되어야 할 것이다.

This study was conducted in order to improve the automatic fishing operation system for anchovy boat seine by comparison with the fishing gear geometry and efficiency using the labor saving nets and the combined type net with midwater trawl. Field experiments were carried out to observe the geometry of nets and improve the fishing operation system by catcher boats. The vertical net opening of fore wing net, square, fore bag net and after bag net of the combined type net were varied in the range of 9.9~12.9. 16.2~28.2, 6.8~12.1 and 9.5~15.2m respectively, when the towing speed was 1.0m/sec and the distance between boats were 100m, 200m, 300m. The vertical net opening of the combined type nets was gradually decreased as function of with increasing the distance between catcher boats. Labor saving net which was maintained the net opening and towing depth stable was more suitable for the automatic hauling operation system by improvement of bag net rather than the combined type nets which was impossible in swallow depth and near to anchovy school. 3 boats hauling operation system of the labor saving net was carried out by crane with power block in 2 catcher boats for improvement of hauling operation and pushing equipment of anchovy cooking system in the processing boat for maintain more anchovy in dry frame. From the results of field experiments, 3 boats hauling operation system with power block and improved cooking system was very 3 boats hauling operation system with power block and improved cooking system was very useful and more practical as hauling time 20~35min and No. of fishermen 12~13 in comparison with the traditional system such as hauling time 30~50 min and No. of fishmen 28~38.

This study was carried out to observe the underwater geometry of the anchovy boat seine by two fishing operation systems. One was a traditional operation system that used a fish detecting boat, another was a new operation system that used the same fishing gear with floats and sinkers in comparison with a fish detecting boat. Vertical opening of the fishing gear that used a casting net, working depth of each part of the fishing gear that used a new operation system was almost canstant, but was gradually shallow in a traditional operation system. Just before hauling net, working depth of each part of the fishing gear that used a new operation system was maintained stable, but was vertically unstable in a traditional operation system because as rear part of the fishing gear was risen up the upper layer. Just after hauling net, working depth of the fishing gear that used a new operation system was also maintained stable, and then anchovy school could be lead to bag net.

In order to improve the gill nets for croaker, Miichthys miiuy which is proper to the fishermen's income ans fisheries resource management, we had studied to the net height of present gill nets (mesh size 160mm, 50 mesh in depth), experimental gill nets-I(mesh size 150mm, 68 mesh in depth) and experimental gill nets-II(mesh size 142mm, 75 mesh in depth) in wter using the gill nets design ans analysis simulation system, and then investigated and analyzed the catch efficiency of each gill nets through the field fishing experiments. The net height of emperimental gill nets-I and experimental gill nets-II in water were estimated respectively about 1.5 times and 1.3 times higher than present gill nets which the net height is about 3.5m as the results of simulation considering the current of fishing fields. Total number of croakers which were caught by the persent gill nets was 62(body length 300~1,200mm), total catch weight was 398.7kg (mean 0.6kg/sheet). Total number of croakers which were caught by the experimental gill nets- I was 68(body length 600~1,100mm), total catch weight was 391.6kg (mean 1.2kg/sheet). Total number of croakers which were caught by the experimental gill nets-II was 28(body length 400~900mm), total catch weight was 99.2kg (mean 0.3kg/sheet).

This paper examines to focus on General Strategy of e-logistics activity for SCM(Supply Chain Management) Build-up, especially the field service logistics integration. And this research analyzes the case study(Business of Strategy Group Unit) Survey involving effective logistics management that leads customer satisfaction, seeking to find out the key elements of competitive policy. Because problems arise from the differences between their goals and structures, which cause each side to feel vulnerable to opportunism or shirking of responsibilities by the other. The goal of a logistics system is to ensure that every family planning client always receives the contraceptives partner wants, and that they are in good condition and have not expired. In order to select, procure, and distribute the right quantities of the right contraceptives, managers of the logistics system must keep informed of the rates of use of each contraceptive and of the quantity of available supplies. As a result, We propose that a firm's e-logistics safe strategy is an important locus innovation and a crucial source of value creation for the firm its suppliers, partners, and customers.

We investigated the activation of the cerebral cortex during active movement, passive movement, and functional electrical stimulation (FES), which was provided on wrist extensor muscles. A functional magnetic resonance imaging study was performed on 5 healthy volunteers. Tasks were the extension of right wrist by active movement, passive movement, and FES at the rate of .5 Hz. The regions of interest were measured in primary motor cortex (M1), primary somatosensory cortex (SI), secondary somatosensory cortex (SII), and supplementary motor area (SMA). We found that the contralateral SI and SII were significantly activated by all of three tasks. The additional activation was shown in the areas of ipsilateral S1 (n=2), and contralateral (n=1) or ipsilateral (n=2) SII, and bilateral SMA (n=3) by FES. Ipsilateral M1 (n=1), and contralateral (n=1) or ipsilateral SII (n=1), and contralateral SMA (n=1) were activated by active movement. Also, Contralateral SMA (n=3) was activated by passive movement. The number of activated pixels on SM1 by FES ( pixels) was smaller than that by active movement ( pixels) and nearly the same as that by passive movement ( pixels). Findings reveal that active movement, passive movement, and FES had a direct effect on cerebral cortex. It suggests that above modalities may have the potential to facilitate brain plasticity, if applied with the refined-specific therapeutic intervention for brain-injured patients.

대표적인 엘니뇨 지수인 태평양 Nino 해역의 표층 수온을 예측하기 위해 비선형 통계모델 중의 하나인 신경망 기법을 적용하였다. 신경망 모델 학습 과정의 입력 자료로 1951년부터 1993년까지의 태평양 해역(120˚ E, 20˚ S-20˚ N) NCEP/NCAR의 재분석 표층 수온 편차의 경험적 직교함수 7개 주모드를 사용하였고, 그 중 1994년부터 2003년까지의 10년 결과를 분석하였다. 모든 해역에서의 9개월까지의 신경망 모델의 예측력은 비교적 우수하였으며, 특히 1997년과 1998년의 강한 엘니뇨의 발달 및 소멸도 잘 예측함을 확인할 수 있었다. 해역별로는 Nino3 지역의 예측성능이 가장 높았으며, 9개월 이후부터는 그 예측력이 급격히 감소하였다. 한편 지역적인 영향이 커 예측력이 낮은 동태평양 연안의 Nino1+2 지역은 9개월 이후에도 예측력의 감소가 관찰되지 않았다.

7xxx series Al alloy has the most attractive properties including its excellent high specific strength, stress corrosion cracking and corrosion-resistance. However, in case of the Al-Zn system, the liquid phase has a transient aspect because of the high solid solubility of Zn in Al. Therefore, transient liquid phase sintering behavior was observed during the sintering process. And the amount of liquid and its duration were influenced by the process variables including heating rate and final sintering temperature. At high heating rates(), the liquid fraction increased during sintering because diffusion was minimized and therefore local saturation could easily occur. The sintered density increased with increasing heating rate.
