The present study was to analyze the trend of registration of design rights in apparel products and tc point out problems of current protection law to design. The research data was total 1,850 design rights in apparel that have been registered to the Korean Patent and Trademark Office from the first design registered in March 1, 1963 through those registered in April 24, 2003. All design rights were analyzed by the year, by the type of product, and by the type of applicant. And also design rights registered under the revised design registration system(without examination) were analyzed by the trait. The results of the study were as follows: (1) Sweater & polo shirts, underpants, and the Korean traditional dress were three major single categories registered in apparel : (2) 54.3% of total design rights in apparel was registered since the legal system of design rights has been revised in March 1, 1998 : (3) Registration by individual applicant were 71.7% of total; (4) About 60% of total design rights were for aesthetic, but in some categories such as vest. brassiere, undershirts, designs for function were more frequently registered than others. And total 68 design rights for the symbol of the organization or uniform, were registered in upper outerwear and pants : (5) As problems of the current legal protection system for designs, the term of “design”(expressed in Korean), double registration of similar designs, malicious intention to register other's trademark as his/her own design. The current legal system for design rights were more used for the product that has relatively long life cycle. And the revised law has been effective in encouraging the registration of design rights. However. the current design law still has some problems to be revised to prevent design rights or trademark infringement.

This study has the purpose of classifying the types of decoration techniques applied to the Korean traditional costume of modern style which are shown in relevant monthly magazines and analyzing the characteristics of the techniques. Findings of the study can be summarized as follows. The types of decoration techniques applied to the Korean traditional costume are classified into single and composite types according to decorative components. In the traditional costume of the former type, a quite many of gold and silver foils and embroideries are found. While, in that of the latter type, a combination of two different decorations, gold and silver foils and embroideries, embroideries and seonchigi or embroideries and stitches is usually used. These decoration techniques are usually applied to some parts of the costume like git, kkeutdong or cuffs, somae or sleeves, jacket or jeogori, the lower hem of the skirt and between joined parts in the skirt. More notably, Korean traditional costumes for women shown in monthly magazines released during the period as mentioned above were investigated to find that a part of the women's clothes, that is, skirt was in most cases decorated with brilliant embroideries. Used together with the techniques, patterns are usually applied onto embroideries and gold or silver foils. Most of the patterns are flower in shape. The main material of the Korean traditional costume is fabrics that have brilliant patterns on the surface and are commercially available irrespective of season. Consequently, since 2010, flower motive patterns which are important in modern fashion trend will be used in embroideries, gold and silver foils. Additionally, embroideries such as seakdong, applique, drawing made with modern style will be the main stream of new HanBok style.

The percentage of overweight people has increased in older people due to the change of body shape (including pregnancy and giving birth for women). Obesity is accompanied by body shape changes; subsequently, there are more pattern design considerations compared to standard body shapes. This paper classifies the upper body shape of overweight women in Korea, analyzes features by body shape and proposes basic pattern design data that reflects the features of plus-size women body shapes. The data on 540 subjects in the overweight group (from 20 to 69 years old)whose BMI was over 25 was selected. The following features by shape were identified in accordance with the upper body shape classification of overweight women. Body Shape1 had lower body obesity with long stature and arms in proportion to the trunk length and represented 22.2% of the subjects. Body Shape2 had most parts near average sizes for overweight body shapes with short height and arms that represented 37.6% of the subjects (the highest ratio). Body Shape3 was the smallest body shape in the four groups with the most distinct body figure and represented 30.7% of the subjects. Body Shape4 (9.4% of the subjects)was the upper body obesity type (the fattest group)and with of the waist bigger abdominal obesity type.

Agricultural groundwater use accounts for 51.8% of total groundwater use, so accurate estimation of groundwater use is important for efficient groundwater management. The purpose of this study is to develop a method for estimating the groundwater use of agricultural (rice farming and dry-field farming) wells using regression tree model based on the measured data of 370 wells. Three input variables of the model were evaluated as being significant: well depth, pipe diameter, and pump capacity, and the importance of each variable was 75% for well depth, 17% for pipe diameter, and 8% for pumping capacity. The daily usage of agricultural (rice farming and dry-field farming) wells by the regression tree model was estimated to be very similar to the actual usage, compared to the previous estimation method proposed by the Ministry of Construction and Transportation. In the future, it is expected that the reliability of the usage statistics will be improved if additional observed data is secured and this classification method is modified.

Customer expectations and requirements for products play an important role in product planning for companies and decision making process for the consumer. These expectations are expressed by product qualities that consumers consider important when they purchase. Therefore, to identify quality elements that reflect consumer requirements would be a useful guide for companies. The purposes of this study are to find out quality factors of apparel product, to identify apparel product quality elements using Kano's theory, to find attributes of product which improvement are required. Women over 20 years-old from metropolitan areas in South Korea participated in the study and a quota sampling method was used. A questionnaire was arranged with four separate subject sections, importance of quality, Kano's questionnaires, and demographics. Data from 525 questionnaires were used for the statistical analysis. The results were as follows: Six dimensions of product quality(i.e., usefulness, performance, aesthetic, symbol, individuality and appearance) were identified. According to Kano's quality elements, performance was categorized into must-be quality which could lead to product dissatisfaction. Usefulness and appearance were categorized into one-dimensional quality which lead to both satisfaction and dissatisfaction. Aesthetic, symbol, and individuality was categorized into attractive quality which could lead to satisfaction. Findings of this study provide both industry and academic researchers with a guide to increase customer satisfaction in the product development process.

With the advances in information technologies and the wide acceptance of IT outsourcing practices, subscription-based information & telecommunications services(ITS) become more available. Convergence and intensified industry competition have made it an imperative for the ITS providers to keep their current customers and acquire new customers at the same time. In this study, we developed a framework for effective customer management based on the factors influencing the post-purchase customer choice: stay with the present provider or switch to another one. Specifically, we classified the factors into four categories: Holding factors, Defect factors, Inducement factors, and Hurdle factors depending on the characteristics of the influence and direction of the influence. Based on the classification, we developed a post-purchase customer choice model for the subscription-based ITS providers. Then, we illustrated a possible application of the model in the context of the broadband Internet access service. The model could be used to increase the competitive advantage of service providers through the effective customer management in the subscription-based ITS market.

It is anticipated that difficulties are encountered in comparing the use levels of food additives between Korean and Codex systems because of the differences in the use level pattern and food classification method. This study was attempted to construct comparison tables between Korean and Codex standards for benzoic acid, food red No. 2, sulfur dioxide and polysorbate as well as for soybean paste, hot soybean paste and intstant noodle. Difficulties were found to be due to the food category system in use levels by additives and due to the mixed pattern of use level setting in Korea in use levels by food commodities. The comparison tables proposed in this study will be utilized momentously by regulatory authorities and food processing industry. This study showed the necessity to pay attention in comparing the use levels of food additives by country and food commodity.

This study was carried out to investigate awareness and attitude of monitors in 206 small sized industries in Seoul and Kyeonggi area toward the occupational health programs using a specially prepared questionnaire. The industries had been running Government-Funded Subsidiary Program since 1998. The questionnaire was designed to be self-administered by respondents. Data were collected for two months from November to December, 1998. Major results are as follows: 1. Between two groups of industries, there were no significant differences in classification, scale, methods of production, existence of trade union, but in type of working pattern and facility ownership there were significant differences. 2. Between two groups of monitors, there were no significant differences in gender, age, marital status, rank, years of education, but in duration of working there was a significant difference. 3. In awareness and attitude of monitors toward their activities and occupational health programs, there was no significant difference by groups of industries, but a significant difference by type and scale of industry, gender, age, years of education 4. It was found that newly subsidized industries were more necessary to provide education programs on occupational health than old industries, and there was a significant difference between two groups of industries in the contents of education needed. In conclusion, it is desirable that the government should develop specific training programs for monitors on occupational health to provide them practical knowledge and specific skills which monitors can apply to their specific situation, and implement the training programs and continue Government-Funded Subsidiary Program for years until small scale industries would have been able to develop and keep their own health management system spontaneously.

Red tide, causes aquaculture industry the damages in Korea every summer, was usually detected by using satellite, aquaculture information was difficult to detect by using satellite. Therefore, we suggests the method for detecting the red tide using the coastal observation and the product from the unmanned aerial Vehicle. As a result, we obtained the high resolution unmanned aerial Vehicle images, detected the red tide by using the unsupervised classification from the true color images and the simple algorithm from the RGB color images. Compared the previous color images, unmanned aerial Vehicle images were clearly classified the ocean color, we were able to identify the red tide distribution in sea surface. These methods were determined to accurately monitor the red tide distribution on the aquaculture fields in the coastal waters where is established the aquaculture.
