생쑥의 건조방법에 따른 지방산 변화를 검토하기 위하여 강화도산 생쑥을 陽翰, 陰翰, 熱風陽燥 및 冷凍翰燥시켜 ethyl ether extract함량과 그 구성 지방산의 함량 변화를 조사하였다.<br/> 1. Ethyl ether extract의 함량은 冷凍翰燥된 쑥이 5.68%로 가장 높았고 熱風翰燥된 쑥이 2.45%로 가장 낮았다.<br/> 2. GLC에 의한 지방산 분석 결과 11종의 지방산 중 주된 지방산은 필수 지방산인 linoleic acid와 linolenic acid외에 palmitic acid가 다량 함유되어 식품 영양학적인 면에서 고무적인 것으로 사료된다.<br/> 3. 건조 방법에 따른 건조쑥의 지방산의 종류에는 차이가 없었으나 그 조성은 상이하였다. 즉 冷凍翰燥된 쑥은 酸化되기 쉬운 高度 不飽和脂肪酸(C_(18:2)+C_(18:3))의 함량이 높을 뿐만아니라 低沸點脂肪酸들의 감소가 가장 적었다. 한편 熱風翰燥된 쑥은 低沸點脂肪酸들이 상당량 감소되었으나 高度 不飽和脂肪酸은 陰翰 및 陽翰시킨 쑥보다 다소 안정하였으며 陽翰시킨 쑥의 변화가 가장 현저하였다. This study was carried out to investigate changes in the compositions of fatty acids according to the different drying methods of raw mugwort. Raw mugwort from Kang-wha was dried with four methods such as sundrying, shady sun-drying, heated oven-drying and freeze-drying. Total contents and fatty acid compositions of the ethyl ether extracts from the dried mugworts were examined. Total contents of the ethyl ether extracts showed remarkable differences with drying methods; freeze-dried mugwort had the highest content (5.60%), while oven dried mugwort revealed the lowest content (2.45%). Eleven fatty acids and four unkown peaks were identified by gas-liguid chromatography; major fatty acids were linoleic acid, linolenic acid and palmitic acid. Fatty acids of mugworts dried by 4 different methods were the same in kinds, but different in their compositions. The content of polyunsaturated fatty acids (C_(18:2)+C_(18:3)) was the highest and the loss of low volatile fatty acids was the least in mugwort dried by the freeze-drying method. The volatile fatty acids considerably decreased in oven-dried mugwort. However, the contents of polyunsaturated fatty acids were a little higher in ovendried mugwort than in sun-dried and shady sun-dried mugwort, and the lowest in sun-dried mugwort.

This paper considers the problem of detecting elliptical curves using Advanced Hough transform. Storage and efficiency problems are over come by decomposing the problem into two stages. The first stage uses a novel constraint as the basis for a Randomined Hough transform to detect the ellipse centre while the second stage finds the remaning parameters using simple but efficient focusing implementation of the Advaned Hough transform. The method is applicable in many situations where previous Hough transform schemes would fail. Results are demonstrated for comolicated image data containing several occluding ellipses.

This paper is to show how to determine the optimal Lot Sizing Rules in a hierarchical Production System. Four selective Lot Sizing Rules, shown excellent among those 9 Lot Sizing Rules in recent studies, are evaluated in terms of production and inventory cost. Six typical demand patterns are generated, and unit production costs and set-up costs are considered as a function of different levels of production system. Also were calculation the total cost of 16 Lot Sizing Sequence generated by the permutation of the four selective rules. Decisions are made on the optimal Lot Sizing Rules at the minimum total cost. Since the total cost varies as a function of the lot size, the upper and lower limit of the lot size is to be estimated within the range of the tolerance level of the total cost. The Economic Lot Range, which the variation of the total cost is negligible, is determind by the two limits of the lot size. Experimentation shows the range is wide enough to provide a greater flexibility in management decision. As the lot size spans from its lower to upper limit, the corresponding penalty costs occur. A functional relationship between total cost and lot size is established through the use of sensitivity analysis. Then the suggested model lays down new criteria by which the penalty cost is optimal.

This paper considers the problem of detecting elliptical curves using multistage Hough transform. The proposed approach is based on the polar and pole definition of conics and its advantage lies in avoiding the propagation of parameter estimation error over the successive stages of the Hough transform. The Proposed method is capable of detecting partially visible ellipses, overlapping ellipses, and groups of concentric ellipses. It presints techniques aimed at improving the efficiency and reducing the memory size of the accumulator array. A set of experimental results is presinted to demonstrate these capabilites of the suggested approach.

Fibrinolytic activity of fermented kimchi and ingredients used for the preparation were assayed by measuring the lysis area on plasminogen-rich fibrin plate. Fermented kimchi and pickled fish sauces from changlan, prwan, and anchovy showed the activity, and the activity of pickled fish sauces were high in the order of pickled changlan, pickled anchovy(pickled mulchi), and pickled prawn. However, the activity of kimchi may not be attributed to pickled fish sauce because kimchi containing fish sauce did not possess activities before fermentation. To investigate fibrinolytic agents in the kimchi if protein, the activities were determined from the samples heated for 30min at 100℃. There was no changes in the activities before and after heat treatment indicating the agents may be components other than protein. Since major changes occur during kimchi fermentation were increased sour taste due to production of organic acids such as lactic, citric, oxalic, and succinic acids, the authentic organic acids present were examined for fibrinolytic activities. The results indicates that the major component posses the activity is lactic acid.

This study is to examine the actual conditions of the houses built for ancestral rites in Jeonnam region with them located at Hwasun-gun, Jangseong-gun and Gwangsan-gu in Jeonnam through the process of literature survey, measurement and analysis. The results of this study are as follows. It is found that the location of the houses built for ancestral rites is mostly found at mountain in back of the village, followed by inside and back of the village. According to the period, it was built distant from the village earlier and it was difficult to approach them and was closed space for family, but it has been opened and generalized to the public people because it was built back or inside the village. The location of the houses built for ancestral was mostly 二-letter type, followed by 一-letter type. 一-letter type can be classified according to the number of rooms. The three rooms type has the basic type of "R1-F-R2〔WVF〕", extra type of "R1(Rs)-F-R2(Rs)〔WVF〕" and division type of "R1/Rs-F-R2/Rs〔WVF〕". the four rooms type has the basic type of "R1-F-F-R2〔WVF〕", extra type of "R1/Rs-F-F-R2/Rs〔WVF〕", division type of "R1(Rs)-F-F-R2〔WVF〕" and other type of "R1(Rs)-F-F-R2/Rs〔WVF〕". The five rooms type has four types such as the basic types of "R1-F-F-F-R2〔WVF〕", "S-R1-F-F-F-R2〔WVF, WVL〕", the extra type of "R1/Rs-R/FH-F-F-R2〔WVF〕" and the division type of "R1/Rs-R/R-F-F-R2〔WVF〕".

The purpose of this paper is to inquire into the matter of the ethical consciousness of advertisement among advertising movements which take the greatest position in modern enterprise. Advertisement can be said to be given much weight in the highly developed industrial society, so much so that it is mentioned as the flower of capitalism. And this advertisement is not familiar to, but causes serious complications among, modern consumers with the so-called "advertisement pollution", "advertisement indigestion" and "advertisement distrust." There has been some severe criticism and problems of the ethical consciousness of enterprise about advertisement. However, from the structure of modern enterprise with the system of mass-consumption which depends on mass-production, it is sure that the advertising movement of enterprise will be increasing, highly developing and multifarious. Business ethics-advertisement ethics can occur as a result of the conscience of managers. One of the most important business of modern managers is to perform changes. These changes, which is accompanied with the social duties of mangers, must be expressed from the ethical dimension. The task of advertisement about ethical consciousness is the matter of mangers conscience before any legal regulation is performed. And so there must be established the ethical system of value from managers. The draft of advertisement must have agreement and identification with the social ethics and legal regulation, and also it should be objective in stimulating purchasedesire. And advertisement movement should be oriented to produce the greatest consumer satisfaction, the greatest freedom of choice and further the greatest national interests, and show the duty consciousness for the public and reduce its vulgarity through self-control. Modern times can be safely said to be times of advertisement. However, the advertisement movement of enterprise, on the one hand, should keep advertisement ethics in connection with its social duty and be performed from the consumeroriented point of view.

A model follwing controller is designed for an uncertain plant using the theory of VSS. The propsoed method is based on the modified condition for the sliding mode to exist. The discontinuous control law speed-ups the reaching phase and reduces the chattering in sliding mode. To further reduce chattering, this discontinuous control law is replaced by a continuous one in a predefined boundary layer neighboring switching hyperplane.
