Many enterprises are performing the production planning computerization for survival in unlimited competing period. But it is very difficult to directly apply many production planning softwares to the domain-specific areas of many small enterprises because one enterprise is different from the others with respect to product type, production process, and order fulfillment method. Practically most small enterprises depend on experienced production managers in production planning, so then many problems such as overtime work and cost have been appeared. The purpose of this study is to develop production planning module for order-made production system in order to reduce overtime works and surplus costs. We developed production planning module with RDBMS, which is fit for small manufacturing company. Developing this software, we use Visual Basic 5.0 to provide GUI environment for the production planning module and Microsoft Access 97 is used to construct Database. This production planning module is applied to enhancement of productivity in M manufacturing company located in Asan.

Agriculture and forest are basis for livelihood in Nepal while both sectors constitute around 40 percent of the national product and over two-thirds of the economically active population is dependent on agriculture. However, radical changes in land use, depletion in crops production and food availability are major threats due to loss of soil fertilityand severe environmental degradation. In this study, we used time series data from 1986/87 to 2005/06 about food crop production and population published by Government of Nepal, Ministry of Agriculture and Cooperatives and Central Bureau of Statistics. Descriptive statistics and ArcGIS were used to assess and map the food security status of Nepalese Terai based on the local food demand and supply system. Food supply to demand ratio(FSDR) was the main idea of assessment. Our results showed that out of 20 districts, only 8 districts were categorised under secured food districts whereas 5 districts were still under food unsecured situation. The analysis further revealed that 7 districts had faced food deficit more than 8-16 times during the last 20 year periods. Data further showed that there was surplus food supply relative to the requirements dictated by FSDR. However, the average FSDR was less than 1.2(less than 20% surplus) exploring fact that most of the districts were not producing sufficient food to cope up the food shock and after 1995 it was relatively stagnant. Our prediction reveals that food supply in Terai even in the future would remain at almost the same level as now, and there will not more than 16-17% surplus by 2021 considering medium vibrant population growth. The findings thus, indicate that Terai may not be a food secure region in the future, even though the region is considered as a food storage house of Nepal. In addition, this paper suggests ways to make future comprehensive case studies more widely comparable in Terai, Nepal.

Consumers have become increasingly more aware of food safety issues, as a consequence of s number of food scandals. Most of these scandals have been related to livestock products. However, most consumers still believe that it is possible to produce safe food at low prices, while a small group of consumers is willing to pay a price surplus for special quality. Organic standards, especially for livestock products, have very few definitions of process quality, and even fewer of these definitions that influence product quality. This paper work to organic milk production and marketing trends in Korea.

본 연구의 목적은 우리나라 기선권현망 멸치어업의 유류비 변동에 대한 영향을 분석하는 데 있다. 연구의 분석 방법으로, 우선 최대지속적어획량(MSY)을 추정하기 위하여 지수잉여 생산모형을 이용한다. 다음으로, 자유어업하에서의 유류비 변동에 대한 기선권현망어업의 생산자 잉여를 추정하기 위하여 생물경제모형을 적용한다. 본 연구의 분석 결과, 면세유 미지급으로 인한 유류비 상승은 기선권현망어업의 멸치 공급에 대한 생산자 잉여에 부정적 영향을 초래하는 것으로 나타났다. 그러나 기선권현망 멸치어업의 유류비 상승이 경영 상태가 좋지 못한 어업인의 퇴출을 유도함으로써 상기 어업의 어획노력량을 최대지속적어획량 수준의 어획노력량($F_{MSY}$) 이하로 감소시켜 멸치 자원의 회복과 더불어 잔존 어업자의 생산자 잉여를 개선시키는 효과를 유인하는 것으로 나타났다.

Questionnaire on utilization of colostrum was carried out in 33 farms. Highest milking cow numbers were 20-40 heads in 45.5% of the farms. Calf numbers were 20-40 heads in 39.4% of the dairy farms and 40-60 heads in 42.4% of the farms. The amount of colostrum production per day was 20-30 kg in 30.3% of the farms and 30-40 kg in 30.3% of the farms. Colostrum intake per calf per day was 4 kg in 45.5% farms. Surplus colostrum after intake by calf was farms (85%) was wasted in 67% of the farms. More than 90% of dairy farms recognize an necessity to use surplus colostrum. Selling price of surplus colostrum was below 1,000 won per kg at 15 dairy farms and 1,000-2,000 won per kg at 4 dairy farms. Colostrum collection and use should be done by the dairy farms of antibiotics free. Quality control of colostrum should be done by testing antibiotics, microbacterium, chemical composition, somatic cells and etc. The colostrum is subjected to cool down below $4^{\circ}C$ just after milking and process for the colostrum products.

This study aims to analyze effectiveness of the resource use under the total allowable catch system (TACs) of Comb pen shell, a species among TAC targeting ones through its stock assessment based on the surplus production model such as the Clark Yoshimoto Pooley (CYP) model. Particularly, this study is separated into five analysis periods in order to understand changes in Comb pen shell resource and its efficient use after TAC system implemented in 2001. The results of this study are as follows. First, five sustainable yield curves (SYCs) and exponential growth functions (EGFs) produced by the surplus production model based on Gompertz growth function to compare before and after implementation of the Korean TAC system show that the TAC system has generated a positive stock rebuilding effect for Comb pen shell caught by the diver fishery since 2001. Secondly, five profits based on differences between the sustainable total revenue (STR) and the total cost (TC) with respect to fishing efforts present that the TAC system has increased efficiency of resource use of Comb pen shell caught by the diver fishery after implementation of the Korean TAC system. In conclusion, the Korean TAC system has increased efficiency of resource use as well as has led a positive stock rebuilding effect for Comb pen shell.

This study sought to find which model is most appropriate for estimating potential yield in the East Sea, Republic of Korea. For comparison purposes, the Process-error model, ASPIC model, Maximum entropy model, Observation-error model, and Bayesian state-space model were applied using data from catch amounts and total efforts of the whole catchable fishes in the East Sea. Results showed that the Bayesian state-space model was estimated to be the most reliable among the models. Potential yield of catchable species was estimated to be 227,858 tons per year. In addition, it was analyzed that the amount of fishery resources in 2016 was about 63% of the biomass that enables a fish stock to deliver the maximum sustainable yield.

There are various types of predictable economic benefits to restoring beneficial uses from contaminated marine sediment cleanup. These benefits can be derived from reduction in aquatic animals died or infected, increase in their consumption recovery, increase in tourism including recreational fishing, reduction in human health risk, increase in amenity and aesthetics, increase in ecosystem integrity, and so on. The paper focuses on estimating the net increase in value for producers and consumers from producing and consuming those fish due to the pollution reduction of marine contaminated cleanup project. Almost Ideal Demand System(AIDS) is employed for estimate of the demand for fish, and the production cost function for fish are determined using market data. The result shows 10.8 billion won per year for economic surplus to the net increase for producers and consumers.
