The purpose of this study is to present the conceptual prototype of Computer Integrated Manufacturing(CIM). To do this, the general characteristic, the function, the method of the application and the case of the introduction of CIM are investigated. The role of production management in CIM is compared with that of Production Activity Control(PAC) To overcome the weakness of the CIM, Artifical intelligence(AI) techniques are introduced. The contribution of this study is to present concrete methodology of operating the CIM.
The distribution characteristics of functional feeding groups and biological evaluation of water quality with benthic macroinvertebrates were investigated from 2013 to 2014 in the mountain streams of Jirisan National Park. Both quantitative and qualitative collection had been performed six times during study periods in twelve sites located at upstream, midstream and downstream of four valleys, Chilsungol, Baemsagol, Daesunggol and Piagol of freshwater ecosystem in Jirisan National Park. As results, the total collected benthic macroinvertebrates were 3 phyla, 4 classes, 11 orders, 37 families, 107 species and 4,028 individuals. In 2013, 3 phyla, 4 classes, 10 orders, 32 families, 89 species and 1,829 individuals were collected. And in 2014, 3 phyla, 4 classes, 9 orders, 31 families, 80 species and 2,199 individuals were identified. The total dominant species was Ecdyonurus kibumensis, and EPT groups occupied 80.39% of total species number. Biotic indices were also compared to site and to season. The dominant index (DI) was highest at the downstream of Baemsagol in the spring of 2013, and the evenness index (J``) was highest at the downstream of Daesunggol in the summer of 2013. Both diversity index (H``) and richness index (RI) were highest at the upstream of Baemsagol in the summer of 2014. The correlation between altitude above sea level and functional feeding groups of benthic macroinvertebrates was also researched in this study. As a result, the species number of shredders and predators have significantly increased according to the increase of the altitude of their habitat. On the other hand, individuals of gathering collectors have increased according to the increase of altitude. The biological water quality was evaluated and compared with several methods in this study, and we suggest that ESB and GPI are more appropriate than KSI and BMI to evaluate biological water quality of mountain stream water.
Stock price is fluctuated by two important factors. The first, the change of expected returns and dividends. The second, the change of the investors' mind which was caused by the optimistic and/or pessimistic on the general trends of the stock price and the specific individual items. In recent year financial managers are giving attention to the methods of the analysis of the security market. This paper's objects are as following ; 1. To study how to rose technical analysis method. 2. To investigate the tools of technical analysis. 3. To arrange the results of precedent studies and develope the tools of the analysis which can be applied to our security market.
Recognizing that MIS planning is fast emerging as an important tropic for both practitioners and researchers, this paper develops key guidelines for MIS planning research. By illustrating similarities between the research streams of MIS planning and the organizational strategic planning, this paper derives three major guidelines from a critical review and evaluation of progress made in the strategic research trend over the last decade. Those are : (1) recognition of hierarchy of MIS planning levels and corresponding hierarchy in MIS planning benefits : (2) specific attention to operationalization of construct to ensure correspondence between theoretical conceptualization and empirical observation : and (3) the adoption of an overarching research framework rooted in the contingency theory tradition.
Expert Systems are emerging as a powerful tool for decision making. Integrating expert systems with decision support systems may enhance the quality and efficiency of both computerized systems. This article examines possible connections between the two technologies and discusses some issues related to their integration.
As decision support systems have become more popular, the need for development of such systems becomes more obvious. This paper takes an in -depth look at the decision support systems and studies their purposes and properties. By investigating the user's need, a set of desirable characteristics for successful DSS are identified. These characteristics are then used to identify a set of essential tools for the builder of the decision support system in order to help him/her to develop a successful decision support system.
The problem which the morden enterprises have to solve is the human and material resources management, because of the shortening of the international resources and the statue of economic stagnation. This problem is conerned with detenmining what inventory level, order point and order quantity should be set in order to minimize the total inventory cost associated with producing a product under the demand fluctuation over a planning horizon. What is called classic inventory control theory does not adequately reflect the realities of a manufacturing enviroment and makes incorrect assumputions as the function of, and, the demand for, individual items which. a manufacturing inventory comprises. Therefore, material requirement planning(M R P) system has been developed as an excellent production scheduling and inventory control technique with wide availability of computers since 1960. M R P is a process of operation planning and control designed to minimize inventory level, to maximize operation efficiency and to improve service level. This paper tries to find the character of the M R P system and suggest the theoretical back-ground of its application to the firm. For the purpose of these objects, this paper compares the M R P system with the traditional inventory control technique. In order to apply and replenish the "MRP" system to the firm ; 1) Make the item level for material requirement planning schedule 2) Prescribe the level of management to use the "M R P" system and educate solving the above problems, "M R P" technique will be effectively used to solve the management problems. We must study the following problems for the use of the "M R P" system. 1) Can not solve by only past data 2) Problem of decision -making of "M R P" 3) Problem of disign of "M R P" system 4) Problem of making the bill of material 5) Problem of developing the software of "M R P"
The study contains that the community distribution of benthic macroinvertebrates and its biological-environmental assessments in urban streams(Gaeumjeongcheon stream, Bansongcheon stream) of Changwon city. During the period of study, 3 phyla, 5 classes, 11 orders, 27 families, 38 species 1,703 individuals of benthic macroinvertebrates were collected. In consecutive order, the species composition is Non-insecta, Ephemeroptera, Odonata, Diptera, Hemiptera, Trichoptera. In Gaeumjeongcheon stream, Asellus hilgendorfii Bovalius was the most dominant species as 18.56% whereas chironomidae sp. was as 32.84% in Bansongcheon stream. Overall biotic indices including diversity, richness, evenness index show higher in Gaeumjeongcheon stream except for dominance index. As a result of biological environmental evaluation and cluster analysis, water quality class of Gaeumjeongcheon stream is Ⅲ, Ⅳ overall when Bansongcheon stream is Ⅴ. Also, the two streams were classified into different groups, which is because of numerous factors such as external disturbances. 본 연구에서는 창원시 도시하천(가음정천, 반송천)의 저서성 대형무척추동물의 군집분포 조사 및 생물학적 환경평가를 하였다. 연구기간동안 조사된 저서성 대형무척추동물은 가음정천에서 총 3문 5강 11목 27과 38종 1,703개체이며 구성종은 비곤충류, 하루살이목, 잠자리목, 파리목, 노린재목, 날도래목의순이었다. 반송천에서는 총 3문 5강 9목 18과 23종 1,553개체이며 구성종은 비곤충류, 파리목, 하루살이목, 잠자리목, 노린재목, 날도래목 순이였다. 가음정천에는 물벌레(Asellus hilgendorfii Bovalius)가 18.56%로 전체적으로 우점하였고, 반송천에는 깔따구과 sp.(Chironomidae sp.)가 32.84%로 전체적으로 우점하였다. 생물지수는 우점도를 제외한 다양도, 풍부도, 균등도가 가음정천에서 더 높은 범위에 분포하였다. 생물학적 환경평가 결과, 가음정천은 전체적으로 수질등급 Ⅲ, Ⅳ등급 이었으며, 반송천은 수질등급 Ⅴ등급이었다. 유사도 분석결과, 두 하천이 서로 다른 그룹으로 묶였는데 이는 외부교란 등의 요인이 작용했을 것으로 판단된다.
The purpose of this study is to develop the extension program for the improvement of fisheries industry in the western coastal area by making the workers in fisheries understand its environment and obtain the knowledge and the skill about it. To attain the above purpose, theoretical and empirical approaches are used in this study. The extention program developed by this study will be a useful source material to the institutes which plan social education for the workers in fisheries. Suggestions for the activation and settlement of the social education are as follows. First, the frequency of the social education about fisheries will have to be increased. Second, the main institutes of social education will have to be diversed to specialize the education line and method. Third, the required subjects in pratical field will have to be selected and educated for improving the effect of social education.
