        현재 우리나라는 외래해충으로 인한 농작물 피해가 심각하기 때문에 이를 해결하기 위한 방제법에 대한 연구가활발히 진행되고 있다. 하지만 아직까지도 수가 기하급수적으로 증가하여 다량의 농작물에 피해를 입히고 있는미국선녀벌레(Metcalfa pruinosa)에 대한 연구는 다른 외래해충에 비해 연구가 미흡하다. 따라서 우리는 미국선녀벌레의 효과적인 방제 및 예찰을 위한 선행연구로서 다음과 같은 연구를 진행하였다. 모종 4종류(상추, 배추, 오이,양배추)와 묘목 3종류(대추나무, 블루베리나무, 아로니아나무)에 2회에 걸쳐 60마리의 미국선녀벌레를 풀어놓고1일 2회씩 4일에 걸쳐서 각 기주식물 마다 미국선녀벌레의 수를 카운팅하여 관찰하였다. 그 결과, 미국선녀벌레는키가 작은 모종 종류에 대해서는 기주 선호도가 거의 없다는 결과가 도출되었고, 묘목 중에서는 키가 약 1M 되는식물들에는 강한 선호도를 보이는 결과를 얻었다. 특히, 4종류의 묘목 중에서 대추나무에 대해서 가장 큰 선호도를보였다.

        Companies build the factory automation system to improve management effectiveness and productivity as prime strategies for sustainable growth. But most companies undergo various trials and errors while carrying out the project without elaborate preparation stage for factory automation. In this study, we tried to verify what factors are critical to effectively building distribution automation system, which is a branch of factory automation system. A consulting model for setting up a Material Handling Automation System by utilizing the Stage-Gate Process, which is product development process was studied. 29 material handling automation projects carried out between the year 1990 to 2013 at K-Company were selected. Interviews with the project managers, operators and maintenance personnels, various records and current status of the projects were used as data for structural equations based on the Milan consulting model and existing researches of factory automation, CIM for material handling automation. Creating effective basis of production, material handling system and energy saving system with expert review, when preparing a material handling automation project, help promote the project planning thus contributing to the performance of the resulting system, which appears though rather weakly in our data. Also the effect of material handling automation can be enhanced through sufficient and effective links to the relevant environments such as production logistics management and automated warehouses. More detailed planning characteristics of project promotion or some time-series data of effective Material Handling Automation System could enhace furthur studies. We propose a consulting model for setting up an efficient material handling automation system.

        Until now, because a new product (or facility) launched in market has been retired from one year of age, we can have had ASL by stub-curve method by Iowa curve. Recently, many innovative products with important role in market like display and solar-cell etc. are more durable and, what are better, they have the constant variance in ASL because of their good quality. Of course, there are some ones like smart mobile phone with relatively big dispersion in ASL. Estimating ASL of products like display and solar-cell etc., the new approach is needed. In this paper a new method applied traditional Iowa curve with accelerated reliability test (indoor/outdoor) etc. is proposed.

        We analyzed the contents of γ-oryzanol, which is contained in brown rice of the nation rice varieties Chucheong, Heukjinju and Sindongjin, by HPLC. Furthermore we also performed experiments on its biological activity, to prove the effectiveness of rice bran. The contents of γ-oryzanol contained in hulled rice showed 1, 587 ppm for Heukjinju, followed by Chucheong(1, 038 ppm), and by Sindongjin(472 ppm). In anti-oxidative activity, we performed an experiment, by measuring the radical scavenging activity of DPPH. Heukjinju showed the best effect, and Chucheong showed the worst effect. In cholesterol lowering activity, Heukjinju showed the best activity and Sindongjin showed the worst effect. In anti-bacterial activity as well, Heukjinju showed the best activity, and Sindongjin showed the worst effect. Through these experiments, we compared the contents of γ-oryzanol, which is contained in hulled rice(Chucheong, Heukjinju, Sindongjin). Also, we found the anti-oxidation effect, cholesterol lowering effect, and anti-bacterial activity of the γ-oryzanol extracts. Based on our research, we expect that γ-oryzanol can work as a new drug, or nutritional supplement.

        There are lack of labour and increase in logistics costs due to rapid change in logistics environments and the demand for logistics. The reality is that over spending on logistics costs are getting worse due to lack of logistics standardization. An example will be excessive logistics costs caused by unsatisfactory use of logistics equipments in wholesale markets. The logistics efficiency is falling due to delays in using logistics equipments and standardization. Therefore, there needs standardization of logistics functions and unit of handling in each stage from packing, unloading, storage, transporting, logistics information and needs logistics standardization on equipments, machineries used for the above. Standard unified with standardization is called specification and if standardization is applied broadly in manufacturing or processing, inspection than each process in terms of production can be managed rationally and labour skills will improve and product quality will be evenly maintained and compatability of each part in terms of assembly will be maintained thus materials and labour could be saved thus results in increasing productivity and lowering production costs. Also, if it is applied in industry at state-level then there will be rationalization in consumption in circulation as in purchase of raw materials, sales of products, purchase of products by consumers and contribute in improving compatibility and fair transactions. This paper is aimed to help in first solving factors affecting the most in improving logistic efficiency among unit load system and logistic hollowization, standardizing logistics base, standardizing logistics information. The study conducted surveys on limited companies but hope that in the future the target companies can be divided further into types, industries and conduct more demonstrative analysis.
