Compared to the bar code which is being widely used for commercial products management, color code is advantageous in both the outlook and the number of combinations. And the color code has application areas complement to the RFID's. However, due to the severe distortion of the color component values, which is easily over $50{\%}$ of the scale, color codes have difficulty in finding applications in the industry. To improve the accuracy of recognition of color codes, it'd better to statistically process an entire color region and then determine its color than to process some samples selected from the region. For this purpose, we suggest a technique to detect edges between color regions in this paper, which is indispensable for an accurate segmentation of color regions. We first transformed RGB color image to HSI and YIQ color models, and then extracted I- and Y-components from them, respectively. Then we performed Canny edge detection on each component image. Each edge image usually had some edges missing. However, since the resulting edge images were complementary, we could obtain an optimal edge image by combining them.

Purpose: This study was performed to develop a scale for evaluation of attitudes toward complementary and alternative therapies (CAT) and to investigate nurses' attitudes toward CAT. Method: The subjects were 263 nurses working at a university hospital in Seoul and Inchon. The personally designed questionnaire was tested for its reliability and validity. Nurses' attitudes to CAT were evaluated using the questionnaire. Results: Cronbach's $\alpha$ coefficient was 0.7405. 23 items were selected by item analysis and 4 factors including application, therapeutic effect, social interest and communication about CAT were classified by factor analysis. The mean score of attitudes and its subcategories were high, especially that of communication was very high. Nurses had a positive response to CAT in several items; acceptance as nursing intervention, its therapeutic value, complement for conventional medicine, and open communication about CAT. Attitudes were different significantly according to education and number of working years. There were high relationships between attitudes and its subcategories except communication. Conclusion: The Scale of attitudes toward CAT was proven to be reliable and valid. Positive nurses' attitudes toward CAT will help the patients be provided with a proper and safe way to take CAT.

Among modem control method, the observer is being used widely because it has the advantage of the guarantee of reliability on financial problem, over heating, and physical shock. However, an existing state observer and a sliding observer have such problems that an experimenter needs to know dynamics and parameters of the system. And also, the high gain observer has such a problem that it has transient state at the beginning of the observation. In this paper, the neuro observer is proposed to improve these problems. The proposed observer complement a problem that occur from increase of gain of High-gain observer in proportion to the square number of observable state variables. And also, the proposed observer can tune the gain obtained by differentiating observational error at transient state automatically by using the backpropagation training method to stabilize the observational speed. To prove a performance of the proposed observer, it is simulated that the comparison between the state estimate performance of the proposed observer and that of sliding, high gain observer is made by using a sinusoidal input to the observer which consists of four layers in stable 2nd order system.

The paper examines the dividend on purchase and revolving funds system of fisheries cooperatives, and discusses how to reform the current revolving funds system. In general, there are two types of dividend that fisheries cooperatives pay to their members : (1) dividend on capital and (2) dividend on purchase or patronage dividend. During the last 5 years from 1990 to 1994, the rate of total dividend ranged from 7.5% to 8.6%. The average rate of dividend on capital and dividend on purchase are 7.3% and 0.5%, respectively. On average, the level of dividend on capital is almost 15 times as high as that of dividend on purchase. Since the dividend on purchase is supposed to be reinvested into capital by the Articles of the cooperatives, it is paid only if there are additional funds available after the payment of dividend on capital and is regarded as the secondary type of dividend. For this reason, even though most of fisheries cooperatives pay the dividend on capital, only a small number of cooperatives pay the patronage dividend. This means that most of cooperatives cannot materialize the managerial function of dividend on purchase to improve their operational efficiency under the current system of revolving funds. Therefore, the paper suggests that in the long run, the system of revolving funds should be reformed in the way that revolving funds could serve to complement equity capital for only a fixed time, after which they are repaid to members.

Furniture should change according to space. Therefore, it is important that the flexibility of the furniture, the functional efficiency, the economical efficiency and the convenience of the furniture of today. These characteristics are also important for seminar tables that are used temporarily by a large number of people. The seminar furniture currently in use has no shielding plate, there are two forms of table and shielding plate folding table. Therefore, in this research, furniture design and product development that can complement the shortcomings of the seminar furniture currently in use were done. Analysis of problems through overseas investigation and domestic market research, design planning and design, and prototyping. We have sought to optimize the volume by applying the characteristics of RTA furniture to develop a lightweight, lightweight, lightweight, easy to install and easy to use shielding plate, and open and closed system. Basically developed two types of shielding board seminar table basic shape and Roll Screen type, we expanded the scope of application such as each color and pattern. In order to reduce the weight, we replaced the parts such as anchor bolts and hinges and the shielding plate with Roll Screen and pursued volume optimization. As a result of this research, it is expected that the system of mechanisms such as packaging standardization and damage prevention for weight reduction and volume optimization will contribute to building competitiveness by domestic office prefabricated furniture industry's original technology.

The mature human braun contains over 10 billion nerve cells (neurons), whose functions are directly related to the acquisition, transfer, processing, analysis, and utilization of all the information. There are also billions of glial cells, which serve primarily to support and to maintain the integrity of the neuron network and to synthesize an essential fatty strucfure, myelin. In the human brain DNA content therefore cell number rises rapidly until birth and then more slowly until $5{\sim}6$ months of age, when it reaches a maximum. While glial cells may be replaced, the more important nerve cell neurons can never be replaced once they are formed. Humans are born with their full complement of neurons and every neuron is as old as each individual. Thus prenatal malnutrition can seriously affect a person's entire life by severely inhibiting the production of neurons before birth.It has been demonstrated that in humans severe malnutrition during the fetal period and in infancy is associated with intellectual impairment. Severely malnourished children have brains smaller than average size and have been found to have $15{\sim}20%$ fewer brain cells than wellnourished childen. There is growing body of literature pointing to malnutrition as a cause of abnormal behavior as evidence that suggests these abnormalities may produce chromosomal damage that may persist forever. Although cognitive development in children is affected by multiple environmental factors, nutrition certainly deaerves more attention than it has received.

Koreans has regarded a fair skin as the supreme beauty emphasizing the white beauty so long, and mugwort and garlic were used as whitening materials. Also, it was recorded that the people of Eub-Rue (挹婁) applied some lard to protect their skin from cold and prevent frostbite, and this must be a great way of beauty care in the light of modern sense. The basic beauty care materials currently used as skin care materials, include natural minerals like loess or mud, and the ones composed of a highly polymerized compound. However, by reason that they are produced without consideration of an individual skin condition, and rather bring about a number of problems leading to skin diseases. To complement this issue, using natural resources would have priority to make up for the weak points. For this, we decided to select and study "Dongeuibogam".

The International Standard Banking Practice for the Examination of Documents under Documentary Letters of Credit (ISBP) is the product by the ICC Banking Commission, October 2002. The ISBP is a practical complement to UCP 500, ICC's universally used rules on documentary credits. It explains, in explicit detail, how the rules are to be applied on a day-to-day basis. It fills a needed gap between the general principles announced in the rules and the daily work of the documentary credit practitioner. By using the ISBP, document checkers can bring their practices in line with those followed by their colleagues worldwide. The result should be a significant reduction in the number of documents refused for discrepancies on first presentation. We are convinced that the benefits of the ISBP will not only be of high importance for users of UCP 500, but also that the practices in the ISBP will survive a UCP revision, or will even be included in the next version of the rule (so call "UCP 600"). Though the above-mentioned benefits of the ISBP, there are several troublesome topics that will probably have to wait for a new UCP revision. It will be a challenge for the drafters of a future UCP to find solutions that will further clarify these points.
