Concept about health is rapidly changed into 21C. thinking logic of customer about food is changed from just food to safety food by disposition of consumption about foodsafety. But government, manufacturer, distribution trader and seller which have different recognitions about foodsafety lose trust of customer. Because they did't focus on thinking changed of customer about foodsafety. Our thinking about rapidly changed food safety being intergrated with IT technology is helping to expand and supply into market. In this article, We'll study Traceability System about cattle and pig related to food. this system was developed in livestock market. In this study, we problems from these systems after studying present construction positions of these systems and purpose of this study is investigation of actual use condition. Also purpose of this study abstracts problems which will be developed and researched.

Recently, the strategy of the age of limitless competition for existence of manufacturing company appears for the enhancement of productivity through the automatic system, the reduction for the cost for standardization and the decision making process for the information system. Especially the critical success factors in manufacturing company can be summarized for the establishment of production visibility through the production management, material & work-in-process management, the establish of the flexible manufacturing system for the changed order priority and the establish of the quality system for improvement of product and process quality. The existing production management systems supply only simple information about production results on real time, can delay quick decision making. And it can prevent acquiring the information about various customer needs and the communication problems with other systems. In this paper, it will show MES system, a solution for the problems of existing production management systems. And through a case study of D company, it will reveal improvement effect on shipment error using MES system and economic analysis for MES itself.

This paper dealt with a kind of heterogeneous vehicle routing problem with known demand and time deadline of customers. The customers are supposed to have one of tight deadline and loose deadline. The demand of customers with tight deadline must be fulfil

Nicotine(2~15mg/kg 2주간, 100mg/kg 회 투여)을 생후 4개월령 수컷 생쥐에 투여한 후, 고환에 미치는 광학현미경적 소견은 다음과 같다. 1. Nicotine 2mg/kg 투여군에서는 정세관과 정세관 주위의 Leydig 세포도 핵과 세포질이 뚜렷한 정상적인 소견을 나타내었으나, 5 mg/kg 투여군에서는 Leydig 세포의 핵과 세포질이 다소 비후되었으며, 염색정도가 약하였다. 2. 10 mg/kg 투여군은 대부분 정세관내의 정자발

본 연구에서는 동해의 오징어 어획량이 급증한 최근 1990~1999년 기간에 주목하여 동해에서의 오징어 어황 변동과 해황과의 관계를 조사하였다. 동해에서 오징어 어획량의 경년변화 특징은 1970년대부터 1980년대 초반에 감소하고 1980년대 후반에 증가하였다. 이것은 기후변화에 따른 regime shifts의 변동과 관계하는 것으로 나타났다. 월평균 어획량은 9-12월까지 풍어기, 3-5월 사이가 흉어기를 보이고, 최대 어획량은 10월에, 최소어획량은 4월에 나타났다. 해구별 안정 어장의 지표로 제시한 변동계수 (coefficient of variation) 값이 1.0 이하로 매년 안정된 어장은 구릉포 연안역과 울릉도 주변해역에서 형성되었다. 또한, 오징어의 최대 어획적수온 16℃를 기준으로 한 어획적수심은 해역이 북상함에 따라 얕아졌다. 이 결과로부터 해역에 따라 조업시의 어획적수심에 대한 차등성을 둘 필요가 있음이 시사되었다. 또한, 조업 어장과 수온의 관계는 흉어기인 4월에 10~14℃이고, 풍어기인 10월에 10~20℃의 범위로서 오징어 어장 형성은 계절에 따른 대마난류역의 확장과 밀접하게 관련된 것으로 생각된다.

This study was to find out the relationships between whiteness, hardness, crack ratio, broken rice ratio, increased grain temperature, moisture content, electric energy consumption, and optimum conditioning of grain temperature for the milled rice efficiency and quality maintenance during the milling process of brown rice at low temperature. There was no significant difference between the whiteness variations of white rice after milling process when the conditioning grain temperatures ranging from 0 to 20oC was used. The crack and broken rice ratios of white rice and the hardness of brown rice decreased with an increased in the conditioning grain temperature. Conditioning grain temperatures of 12, 20oC are applicable to appropriated standard of temperature (15oC) after milling process. In the case of low temperature of grain, there was steadily increase the rate of changing moisture contents because of dew condensation. There was 2.62~14.28% decline of electricity energy for milling process when the temperature of grain was higher than 0oC. Therefore, it needs to control temperature over 10oC for appropriate milling in winter season.
