본 연구는 기호성이 높으며 여름철 고온에 강한 새로운 tall fescue 품종을 구명하기 위해 초지조성 후 5년째인 1997년 방목기간 동안에 북제주군 한림읍 이시돌 목장에서 홀스타인 육성우(방목개시시 체중 110kg 내외)를 이용하여 구당 250(50mx50m)의 면적에서 2처리(T1 = Fawn tall fescue + orchardgrass + perennial ryegrass + white clover, T2 = Roa tall fescue )

본 연구는 아연폐광지역의 토양에 토양개량제를 처리한 후 구절초와 층꽃나무의 생장반응을 연구함으로서 생태계 복원을 위한 기초자료를 얻고자 실시하였다. 아연폐광지의 토양은 유기물 함량ㅇ이 낮았고, 토양 중 중금속 이온은 Zn의 함량이 가장 높았고 Pb, Cu, Cd순이었다. 아연폐광지역 토양에 슬러지 처리 시 유기물 함량이 가장 높았고, 중금속 이온 함량은 토양개량제 초리구간의 차이가 적었다. 생육반응을 보면 구정초와 층꽃나무 모두 슬러지 처리구의 효과가 나타났다. 구절초와 층꽃나무의 가용성 단백질, 엽록소 함량, 엽록소 형광 반응은 슬러지 처리구에서 가장 높았고, 광함성량과 증산량도 슬러지 처리구에서 높았다. 중금속 축적량은 구절초는 슬러지 처리구에서 낮았던 반면 층꽃나무는 슬러지 처리구에서 높았다.

The film with methylcellulose(MC) and grape seed extract(GSE) were prepared by casting their aqueous solution at 80oC and dryng at 23oC for 48 hrs. Effect of grape seed extract (GSE) on the barrier permeabilities and the thermomechanical property of methylcellulose(MC) film was studied. The barrier permeabilities and the thermomechanical property of MC films containing various contents of GSE were evaluated in terms of water vapor, oxygen permeabilities, and dynamic mechanical analysis(DMA). The rate of water vapor permeability of MC films decreased with GSE contents in the MC films. Also, the rate of oxygen permeability also decreased with GSE contents indicating higher oxygen barrier property of the MC film. The results showed that GSE had a good miscibility with MC and acted as a plasticizer for MC films resuling in lowering the glass transition temperature of the film.

The spiral vibration heat exchange dryer moves, dries continuously and mixes uniformly particles on the spiral heating plate. So this system is adequate to dry the powder-type food materials. The mass and heat balance equation is used to design dry capacity and water content measurement, sieve analysis and vibration moving test are practiced to lay out the spiral plate. Spiral vibration dryer(300 kg/hr) is manufactured and tested by Dashida powder of 4.8% water content at 80~85oC. The frequency of vibration motor is operated 45Hz, 55Hz, 60Hz and the product mass per time is measured by digital scale. The water content of product is 1.0~1.6% and the dry efficiency is 67.4~78.2%. The spiral vibration heat exchange dryer make 125~363 kg/hr of Dashida dehydrated with temperature consistency and without dust in case.

All managers should consider both of job performance and job satisfaction as influential key results to be achieved by people at work. One without the other is simply insufficient to meet the high standards of today's workplace. Some workers achieve a sense of personal satisfaction from their jobs while others do not. the others achieve high levels of task performance while others do not. The test of a manager's skill in building value added jobs is to discover what work means to other people, and then to create work environments that help them achieve high levels of both performance and satisfaction. this study set out to investigate the job satisfaction of the employees at work station along with the needs resulting from exploding population of salary citizens. This paper aims to survey and analyze the job satisfaction of the workers and a potent influence factors of Job stress for organization management.

변색된 종자에서 분리된 P. wasabiae에 접종된 종자는 평균 52.4%의 낮은 발아율을 보였으나 benomyl 침지처리에 의해 발아율이 83.3%로 향상되었다. 멸균 토양에 파종된 접종종자는 28.0%의 먹들이병, 12.7%의 모잘록병 발병률을 보였으나, benomyl로 침지처리된 종자는 먹들이병 6.0%, 모잘록병 4.7%의 낮은 발병률을 나타냈다. P. wasabiae가 접종된 토양에 공시 약제로 처리된 종자를 파종한 결과 먹들이병 발병률은 약제를 처리하지 않은 종자의 32.0%에 비해 benomyl 침지처리에서 12.0%로 발병이 억제되었고, 모잘록병은 10.7%의 가장 낮은 발병률을 보였다.

본 연구는 오이와 토마토의 플러그 묘 공정육묘시 발생하는 도장 억제를 위한 적생광 처리시기와 광도의 영향을 알아보기 위해 실험을 수행하였다. 일몰 휴, 야간 및 일출 전 적색광 처리시기에 의한 묘의 도장억제는 일몰 후 처리가 오이와 토마토의 초장을 각각 21.3%와 14.2%로 가장 크게 억제하였고, 경경의 굵기도 가장 두꺼웠다. 엽록소함량은 토마토에서만 일몰 후 처리된 플러스묘의 함량이 대조구에 비해 유의적으로 높게 나타났다. 적색광 초리시기에 의한 두 작물의 건물중을 보면, 대조구에 비해 지상부 건물중은 일몰 후와 일출 전 적색광 처리에 의해 유의적인 감소를 보였다. 오이와 토마토 플러그묘의 T/R율은 일몰 후 처리에서 타 처리에 비해 가장 작았으며 조ㅈ직의 충실도는 밀몰 후 처리에서 가장 크게 나타났다. 광도별 처리에 의한 초장은 오이와 토마토 플러그묘 모두에서 광도가 증가함에 따라 초장은 감소하였다. 하배출, 절간장 및 엽면적도 초장과 유사한 경향을 나타내었다. 두 작물 모두 경경과 엽록소함량 및 조직의 충실도는 광도가 증가함에 따라 증가하는 경향을 보였다. 하지만 지상부와 지하부의 건물율은 광도의 증가에 따라 감소하는 경향이 나타났으며, 오이는 2 및 8 μmol·m-2·s-1의 적색광 처리구에서 토마토는 8 μmol·m-2·s-1처리구에서 가장 낮은 T/R율을 나타내었다.

Each method for economic evaluation has its own characteristics. Therefore adoption of each of them in evaluation production investment project results in many problems. Hence combination & modification of them are required to perform more accurate evaluation about investment project. This paper discuss evaluation method of investment projects expansion and replacement investment on each line or individual in the production. Generally investment evaluation method has add to a few method by Subsidiary means with use a especial method. And then in this paper, a Taguchi Techniques is presented, which may be effective to the facilities appraisal or improvement. We propose a decision model to incorporates the values assigned by a group of experts on different factors in production. Using this model, SN ratio of taguchi method for each of subjective factors as well as values of weights are used in this comprehensive method for reducing production rate in production management.

The purpose of this paper is to provide research about the manufacturing strategy situations of the Korean manufacturing company. And this paper is a part of Modeling on Manufacturing Strategy. We emphasizes the importance of dynamism and complexity on the competitive environment, and classify the manufacturing strategy by trade-off model, cumulative model, sandcone model, strategic fit model, and competitiveness model.

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 sied to feel vulneralbe 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 strategy is an important locus innovation and a crucial source of value creation for the firm its suppliers, partners, and customers.

In this work, a finite element model is presented for geometrically non-linear analysis of shell structures. Finite element by using a three-node flat triangular shell element is formulated. The non-linear incremental equilibrium equations are formulated by using an updated Lagrangian formulation and the solutions are obtained with the incremental/iterative Newton-Raphson method and arc length method. Some of results are presented for shell structures. The obtained results are in good agreement with the results available in existing literature.

Recently, in order to stay at predominance in the global infinity competition, most of companies have been reducing the cost in many fields of industry. First of all, the reduction of the logistics cost have been recognized greatly as the company value ri

글라디올러스의 생육에 있어 엽초의 역할을 알아보기 위해 제거시기와 제거수를 달리하여 엽초제거 한 후 생육반응을 조사한 결과, 생육초기의 광조건에 관계없이 엽초를 모두 제거함으로써 화경장과 화수장이 짧아졌고 개화수도 적어졌으며 특히 제거시기가 빠를수록 생육이 현저하게 저조해졌다. 그러나 엽초제거에 따른 개화소요일수는 차이를 보이지 않았다. 엽초를 엽위별로 제거한 처리구에서 엽초 1, 2 및 3매를 제거한 것은 생육 차이를 보이지 않았으나 글라디올러스의 초장 생장에 비례적으로 자라난 4번째 엽초를 포함하여 제거한 엽초 4매 제거구에서 타 처리구에 비해 화경장이 25cm이상 작아졌으며 화수장도 짧아지고 개화수도 적어졌다. 또한 줄기기부도 비정상적으로 굵어졌다.
