This paper aims to understand the points which the Board of Directors of the National Federation of Fisheries Cooperatives System has proposed, and to find some improvement. This Fisheries Cooperatives previously had a single board system operating two small board rooms which became independent within the two sectors of credit and .provision in addition to the existing board of directors. This is a very unique board of directors system which is not found in cooperatives in our country nor in the business world. This change of the board of directors of the Fisheries Cooperatives is ascribed to the reorganization of the system into a completely independent division system, which operates business separately based on each sector as opposed to the previous multiple cooperatives system. However, a plural board of directors system does contribute to the improvement of managerial efficiency by strengthening the self-control of each independent business section, but deepens conflicts between its internal organizations, and brings about a reverse function which might deteriorate both the controlling power of a systematic organization and the coordinating power between sectors. This paper made an analysis of acceptors' attitudes toward the board of directors of the fisheries cooperatives system by regulating all the staff directly related to the operation of the board of directors of the fisheries cooperatives system as a group of acceptors and by selecting one hundred and fifty persons among the staff as a sample. The inquiry into acceptors' attitudes was made using questionaries, and the data for this investigation was processed and analyzed using a statistical method. The contents of this paper are composed of I. an introduction, II. the findings of the questionary investigation, III. the overall opinion for the improvement of the board of directors system, and IV. a summary and conclusion.

We studied in order to find out suitable amounts of board by visual effects to establish indoor boards and human psychological effects by several board designs. Thirty students of C university were tested in constant temperature/humidity room and interviewed after tests. The experimental visual images were projected from 54' TV. As a result, the board length that showed high preference and satisfaction was the 90cm both horizontal and vertical direction. We found that vertical board gave an impression of a linear and narrow shape and the horizontal board gave wide space and cool feeling from psychological analytical study. The factors affecting satisfaction in horizontal direction were refreshing, intimacy, beauty, area, splendor and those in vertical direction were a sense of security, beauty, texture, intimacy, continuity, extensity, natural feeling. We got 5 factors from the result of factor analysis in order to get psychological factor axis. Those were pleasantness, artificiality, openness, dynamics, refinement. By multiple regression analysis, the factor pleasantness had the highest impact on visual satisfaction on scenary. The study on psychological factor difference by analysis of variance showed that psychologically feeling amount about pleasantness, artificiality, dynamics, refinement, and openness had statistically meaningful difference despite of board direction. We found that the 90cm had a tendency as a changing point leading image change by the investigative analysis of board direction based on factor points.

Fuel cells have the potential of providing several times higher energy storage densities than those possible using current state-of-the-art lithium-ion batteries, but current energy density of fuel cell system is not better than that of lithium-ion batteries. To achieve the high energy density, volume and weight of fuel cell system need to be reduced by miniaturizing system components such as stack, fuel tank, and balance-of-plant. In this paper, the thin flexible PCB (Printed circuit board) is used as a current collector to reduce the stack volume. Two end plates are made from light weight aluminum alloy plate. The plate surface is wholly oxidized through the anodizing treatment for electrical insulation. The opening rate of cathode plate hole is optimized through unit cell performance measurement of various opening rates. The performances are measured at room temperature and ambient pressure condition without any repulsive air supply. The active area of MEA is 10.08 $cm^2$ and active area per a unit cell is 1.68 $cm^2$. The peak power density is about 210 mW/$cm^2$ and the air-breathing planar stack of 2 Wis achieved as a small volume of 18 cc.

The steam generator tubes of power plant damaged by sliding wear due to flow-induced motion of foreign object. Amount of wear have been predicted by Achard's wear equation until now. However, there are large error and low reliability, because this equation regards wear coefficient(k) as constant. The sliding wears tests have been performed at room temperature to examine parameters of wear (wear distance, contact stress). The steam generator tube material for wear test is used Inconel 600 and foreign object material is used 304 austenite stainless steel. The sliding wear tests show that the amount of wear is not linearly proportional to the wear distance(for 374 austenite stainless steel). According to experimental result, wear coefficient is not constant k but function k(s) of wear distance. The newly modified wear predictive equation V=k(s)F have small error and high reliability.

Palm 유로 유열처리한 라면제품을 태양광선구, 실내보존구, 항온기보존구 및 골판지상자구 등의 처리구로 나누어 20주동안 저장하고, 경시적으로 산가, 과산화물가, TBA가, 지방산조성 및 요오드가 등의 지방산화이상을 조사한 결과는 다음과 같다. Al증착 film포장지로 밀봉하고 골판지상자에 넣어 실온 암소에서 저장하면 산가, 과산화물가, carbonyl가 및 TBA가는 완만하게 증가하여 5개월 경과 후에도 완전한 품질을 보였다. 관능검사에 있어서의 산패취도 5개월후까지는 인정되지 않았다. 실내보존구 및 항온기 보존구의 라면은 완만한 산화이상을 보여 저장 18주에 산패취를 확인하였으나, 태양광선구의 라면은 저장 10주부터 다소 크게 산화가 일어났으며, 이때 산패취를 확인하였다. 산가, 과산화물가, carbonly가, 및 TBA가는 각 처리구 공히 저장기간 동안 증가하였으며, 태양광선구에서 그 증가이상은 현저하였다. 특히 TBA가는 태양광선구에서 저장 10주이후 급격히 증가하여 14주에 그 정점을 이루고 다시 감소하였다. 저장초 그리고 저장 18주의 태양광선구 및 항온구의 라면 유지에 대한 지방산 조성을 살펴본 결과 항온구에선 큰 변화가 없었으나 태양광선구에선 저장초의 지방산조성에 비하여 oleic acid등 불포화지방산의 상대적인 감소이상을 볼 수 있었으며 저장 중 요오드가의 감소가 이런 사실을 뒷받침하고 있다.

An indoor environmental monitoring system using IEEE 802.15.4 based wireless sensor network is proposed to monitor the amount of pollutant entering to the room from outside and also the amount of pollutant that is generated in indoor by the building materials itself or human activities. Small-size, low-power wireless sensor node and low power electrochemical sensor board is designed to measure the condition of indoor environment in buildings such as home, offices, commercial premises and schools. In this paper, two query models, the broadcasting query protocol and flooding query protocol, were designed and programmed as a query-based routing protocol in wireless sensor network for an environment monitoring system. The flooding query routing protocol in environment monitoring is very effective as a power saving routing protocol and reliable data transmission between sensor nodes.

본 연구에서는 사회공헌활동에 대한 건설기업들의 인지도를 분석하고, 대기업과 중소 건설기업의 사회공헌활동을 비교해 보았다. 이를 위해 국내 사회공헌활동에 대한 설문조사와 전문가 조사를 통해 비교·분석하고 시사점을 도출하였다. 분석결과 건설기업들은 대체로 사회공헌활동의 필요성을 절감하고 있었는데, 중소 건설기업들은 대규모 기업들에 비해 필요성의 인식 정도가 낮았다. 중소 건설업체 CEO 및 경영진의 사회공헌 관심도는 아직은 부족했다. 사회공헌활동의 추진형태는 전문성과 네트워크 때문에 모두 직접사업 보다 NGO와 파트너십이 많았다. 향후 사회공헌활동 활성화를 위한 전략은 다음과 같이 요약된다. 먼저, 중소기업 CEO들에 대한 인지도 제고와 사회공헌활동 참여를 독려할 필요가 있다. 사회공헌활동의 필요성은 대체로 공감하고 있지만, 대기업을 제외한 중소기업의 경우 참여한 적이 없는 경우도 굉장히 높게 나타나기 때문이다. 둘째, 사회공헌활동을 위해 NGO와의 유대 및 정보 등을 공유할 필요가 있다. 많은 건설기업들이 NGO의 전문성, 전담인력 부족 등으로 NGO와의 파트너십을 선호했는데, NGO의 건설기업에 대한 생리 이해부족, NGO 관련 정보을 얻을 수 있는 인프라 부족 등을 문제로 지적하였다. 이는 특히 중소규모 건설기업에서 두드러졌다. 셋째, 원활한 사회공헌 활동을 위해서는 예산지원이 필요하고 전담인력이 확보되어야 한다. 그리고 외부적으로 정부의 제도적인 지원도 마련되어야 한다. 마지막으로, 건설기업의 사회공헌활동에 대한 홍보가 강화되어야 하고 벤치마킹할 수 있는 사회공헌활동 프로그램 등을 개발해야 한다. 특히 중소 건설업체들은 이러한 여유와 능력이 부족하므로 건설산업 사회공헌재단의 역할이 강조된다.

관광개발이 지역경제에 미치는 파급효과를 분석하기 위하여 투입-산출분석, 관광소득승수분석, 노동창출효과분석 등의 방법을 사용해 왔으나, 2차적 자료가 부족한 소지역을 대상으로 하는 분석에는 적응하기 어려운 실정이다. 본 연구에서는 관광사업체를 대상으로 하는 현지 조사에 근거하여 관광객으로부터 관광사업체로 유입되고 사업체에 의해 지출되는 화폐흐름을 추적하는 '관광지출흐름분석' 방법의 타당성을 검증하고자 한다. 3개의 사례지역을 대상으로 한 조사로부터, 이 방법이 관광개발이 유발하는 연간 지출액의 규모와 그 지리적 범위를 추정하게 하고 생산액, 노동유발효과 등 지역경제에 대한 의미있는 지수를 측정할 수 있게 함을 알 수 있다.
