With suffering financial crisis in 1997, Korea's fashion market has grown in the direction that satisfies the reasonable price and diverse consumer's sensitivity and needs. The aim of this study is to examine whether the cutting portion in the waist line is surely necessary for designing the jacket pattern in men's wear, by closely examining the effects of the cutting portion in the waist line on the external appearance and functionality given designing the jacket pattern in men's wear for the standard body type in 20s. The results of the study are as follows. As a result of evaluating the external appearance, when having evaluated by dividing into 14 items such as the whole surface, the side, and the back side, the experimental clothing, which wasn't cut the waist line, obtained the highest mark in 13 items and, the significant difference was indicated in 10 items except 4 items. As a result of evaluating performance, the experimental clothing, which wasn't cut the waist line, obtained the highest mark in 13 items among 25 items in the total. Next, the cutting portion in the waist line obtained the highest mark in 10 items for the experimental clothing with opening in 1.0cm. The next was indicated to be in order of the experimental clothing with 1.5cm and the experimental clothing with 0.5cm. Given seeing the above result, the cutting portion in the waist line given designing the jacket pattern for the standard body type in 20s could be known that the experimental clothing with the most excellent mark in the evaluation of performance was all the experimental clothing with 0.0cm whose waist line wasn't cut.

The elderly population in Korea is growing rapidly and their nutritional status is not acceptable. Data were collected from the self-administered questionnaire of 495 free living elderly, over 65years old, in Korea to asses the intake and consumption pattern of milk and dairy products. The questionnaire contains demographics, health related characteristics, and perception on milk, and consumption behaviors of milk and dairy products. Most of the elderly subjects understood that milk is good foods in terms of nutritive value and health. And 67% of the subjects satisfied with the sanitation status of milk on the markets. The kind of milk that majority of the subjects consumed was whole milk, and only 5.1% of them consumed low fat milk. Less than 20% of the subjects consumed milk everyday, living alone group consumed milk less frequently than living with others. It was found that the majority of the elderly subjects did not meet current recommendation for milk. Liquid and curd type yogurt were the major dairy products used among elderly, and the reasons were good taste and digestion. They believed that these kinds of dairy products help constipation and digestion problems. The price of milk was ranked for the first factor needed to be considered for milk and dairy products consumption in elderly korean.

Log scaling which decides a quality grade of log is influence the price of log at the market. It is the one of important works at the field until now. So it remains using a ruler traditionally. This study evaluated the automating program through compared the automating program with using a ruler for log. The automating program used libraries of OpenCV concerning image processing algorithm to measure log diameter for scaling. In addition, it applies two panels of checkered pattern beside a pile of logs and tapes on the surface of a log diameter to find a correct value. We analyzed statistical mean difference of both log diameter and volume. In conclusion, the automating program after applying check panel and taping ins't different using a ruler. Therefore we need to considerate about applying it for improving Forest Administration.

The purposes of this study were to identify the brand positioning of children's wear according to fashion life style and to construct brand positioning maps by using multidimensional scaling (MDS). A total of 222 responses were collected from married women aged 25 to 35 through questionnaire. Cluster analysis on fashion life style factors identified three groups: Fashion Indifference group (34%), Fashion & Individuality Oriented group (27%) and Rationality Oriented group (37%). ANOVA revealed significant differences among the three groups on the six fashion life style factors. MDS analysis showed that three segmented groups evaluated nine children's wear brand for seven attributes(color, design, price, utility, quality, brand name, fashion).

To deal with the modem intellectual criminal acts, various efforts are tried. Especially, it is not difficult to watch the recent activities to analyze the criminal characteristics spatially using computing and GIS technology In this study, the spatial features and patterns of crime are investigated. The crime is reconstituted with respect to assault, larceny, robbery, and rape, then the variables are derived based on the theory of criminology. The kernal density analysis are performed to investigate the criminal distribution, and the correlation between the main criminal causes and the criminal outbreak is examined by buffering analysis. In addition, the land price and land usages are correlated with social-economic factors of criminal patterns.

The production of electricity and the pattern of consumption in competitive electricity market are changing. The price of electric power in spot market will be varied by the economic electricity availability of generation utilities and electricity consumers. DSM(demand-side management) is a method which provides simultaneously economics to utilities and consumers as main participants in electricity market. In this paper, it is argued that the effect of DSM in competitive electricity market for consumers, generation utilities, and transmission utilities.

Long-term forecasting of seasonal time series is critical in many applications such as planning business strategies and resolving possible problems of a business company. Unlike the traditional approach that depends solely on dynamic models, Li and Hinich (2002) introduced a combination of stochastic dynamic modeling with filter bank approach for forecasting seasonal patterns using highly coherent(High-C) waveforms. We modify the filter selection and forecasting procedure on wavelet domain to be more feasible and compare the resulting predictor with one that obtained from the wavelet variance estimation method. An improvement over other seasonal pattern extraction and forecasting methods based on such as wavelet scalogram, Holt-Winters, and seasonal autoregressive integrated moving average(SARIMA) is shown in terms of the prediction error. The performance of the proposed method is illustrated by a simulation study and an application to the real stock price data.

Energy consumption of sensor nodes is minimized because it has limited energy generator in wireless sensor network. Electronic shelf label system is one of application fields using wireless sensor networks. Battery size of small apparatus for displaying price is restricted. Therefore its current consumption have to be minimized. Furthermore the method for minimization of peak current would be considered because life cycle of coin battery used to display or RF is vulnerable to intensity of drain current. In this paper, we analyze current consumption pattern of low-power electronic shelf label system. Then we propose the method for minimization of current consumption by modification of software and hardware. Current consumption of the system using proposed method are approximately 15 to 20 percent lower than existing system and the life cycle of the system is approximately 10 percent higher than existing system.

The purpose of this study is to analyze the actual condition and problems of current ready-made shrouds. Current shrouds were formed after the 20th century and therefore are quite apart from its traditional precedents of Chosun Dynasty. In this respect, several problems can be pointed out. 1. The use of natural colored hemp as a primary textile of current shrouds is far from our tradition. Silk, ramie, and cotton have to be used together with hemp. Also, more variety of colors can be used other than natural white. 2. The size of ready-made shrouds has to be categorized at least into three: large, medium and small 3. The pattern and sowing method of Dopo(도포) and Wonsam(원삼) should be corrected in line with those of the traditional Dopo(도포) and Wonsam(원삼). 4. The design and items of current ready-made shrouds have to break away from the standardized convention and should seek more of a variety that our rich tradition provide. 5. The rational index should be suggested so that consumers can compared the quality and price of ready-made shrouds available at their hands.

In combining dispersed optimization models, either primal or dual(or both) decomposition method widely used as an organizing device. Interpreting the methods economically, the concepts of price and resource-directive coordination are generally well accepted. Most of deomposition/ integration methods utilize either primal information of dual information, not both, from subsystems, while some authors have developed mixed decomposition approaches employing two master problems dealing primal and dual proposals separately. In this paper a hybrid decomposition method is introduced, where one hybrid master problem utilizes the underlying relationships between primal and dual information from each subsystem. The suggested method is well justified with respect to the flexibility in information flow pattern choice (some prices and other quantities) and to the compatibility of subdivision's optimum to the systemwide optimum, that is often lacking in conventional decomposition methods such as Dantzig-Wolfe's. A numerical example is also presented to illustrate the suggested approach.
