As individual family has fewer children, market sectors targeting children's goods upgrade their products quality and price. Children's wear used to be for casual activity or going to school. Recently, occasions in which children are dressed up are getting increase, such as wedding, concert or family gathering. Therefore, the industry sector of formal wears for school boys are growing. The purpose of this study is to research and grading of formal wears for school boys to improve their fit and comfort. The selected items as formal wear were tailored jacket, tuxedo, tail coat and pants. Based on the grading increments of the industry, grading was done far 7 years and 11 years old school boy for each item. Like the pattern alteration, grading increments were tested and altered through wearing tests. The final increments were suggested as the 'researched grading increments'. The results and conclusions are: 1. Appropriate size allowance, ease amount and lengths for boys are different from those far adults. The difference should be applied for boy's wear. 2. Grading increments for an age group are different from other age group. For example increments of 7 from 9 are different from that of 11 from 9. It is because a certain part grows faster during a certain age whereas other part grows faster during different period. Therefore grading for children should reflect their growth rather than same size increments which is common in adult size chart.

This paper is to analyze the past and present consumption pattern of fishes aquacultured in marine waters and thus to draw the policy direction to enhance the competitiveness of marine fish aquaculture in Korea. At present, the volume of meat consumption is surveyed to be more than that of marine fish, but it is revealed that fish consumption will become more increasing in the future according to the rise of the income. The survey shows that the consumption of fish is highest in the fall, and among the various patterns of consumption, live fish, so-called susi, is surveyed to be highly dominant. It is revealed that fish is enjoyed because of the special savor, diverse nutrients, and the prevention of adult diseases. Natural fish Is revealed to be more preferred to aquacultured one due to the sticky flesh quality and the low probability of the remained after the production process antibiotics, so that it is necessary to enhance the taste quality and make a clean cultivation to capture more market demand. Consumption of high-quality fish seems to become high in more than middle class and consumption of fish are estimated to increase in the future, more than that of meat if income level of the people increases. Also, if we try to make our high-quality fish become popular among the public and competible with the imported fish from abroad, it is recommended that they must lower production price by cost reduction and try to differentiate it by taste and environmental safety, etc. It was revealed that the significant factor in demand function for fish is income and it is almost the only factor affecting that demand. Also, it was revealed that the most significant factor affecting preference of fish is income and it Is almost the only factor affecting the preference. Therefore, we can ascertain that if proper goods can be distributed, demand for and preference of fish may increase according to the increase of income in the future.

The CAD/CAM system for the manufacturing automation is the newest technology in mechanical engineering area and becomes the important research subject nowadays. Most of all hardwares and softwares for the CAD/CAM system used in the our manufacturing companies such as automobile company are developed by the foreign country and the purchasing price of them is very expensive but their applicability to a certain area is very limited. This study was conducted to develope a CAD/CAM system for the design and the automatic manufacturing of the iron pattern shaped with 3 - dimensional free curved surface, and to test its applicability to the design and the manufacturing of the rotary blade. The results obtained from the study are as follow; 1. The CAD system which can process graphic procedures from the free curved surface shaped data was developed with personal computer. 2. The CAM main program was developed. This main program could produce CL data from CAD data file by checking the tool interference according to the cutting mode. 3. The sub. program which can simulate the tool trace from the CL data was developed. 4. The post processor for the Deckel FP2NC NC milling machine from CL data file was developed and the sub program could transmit NC program through modem to NC milling machine was developed. 5. The developed CAM system seemed to be applicable to any other system. Because the measuring results of the cross sectional thickness of the plastic model from the manufacturing iron pattern by the system showed that this system could properly check the tool interference. 6. In took 75~90 hours to manufacture two iron patterns of rotary blade. For the sake of convenience in applying to the other systems, this system was developed in BASIC and FORTRAN computer language and minimum portion of machine language as possible.

This study attempts to discern the purchasing pattern of urban husbands' clothing in Korea. Studies on this subject in other cultures show that wives play lesser role in purchasing activities of their husbands' clothing in the industrial societies rather than in the pre-industrial ones. It would be interesting to know the way selecting and buying husbands' clothing in urban Korea. Specifically questions to be answered include: Who makes the decision in selecting in kinds of husbands' clothing and who buy them? Data for this study has been collected through structured questionaire survey for 606 married women in the City of Seoul including 192 mothers of elementary school students, 58 elementary school teachers, 210 mothers of middle and high school students, 56 mothers of undergraduate students, and 47 college professors. Since most women of our sample are relatively high in educational level and working for various educational institutions, the findings of this study should not be generalized as a general trend of urban Korea. Major findings of this study include: 1) Purchasing husbands' clothing is not entirely wives' domain. The degree of participation on the part of wives in selecting and buying of their husbands' clothing depends upon the kinds of clothings. If it is for such items as underwear, socks, handkerchief, or umbrella, which are relatively easy to choose in terms of size, outlook, and price, more wives do the job. Other- wise, however, husbands more actively participate in selecting and buying their own clothings such as shoes, overcoats, neck tie, and formal wear. 2) In terms of clothing behavior of husbands, it seems to be a general trend that husbands select their clothings, but wives buy them. 3) Variables related to socio-economic status seem to affect the clothing behavior of husbands. Those who more actively participate in selecting and buying their clothings include: husbands whose wives have a job outside thier family, younger in age, middle school or high school graduates rather than college graduate or husbands with far lesser education, and husbands who live in western style houses rether than in traditional Korean houses.

The purpose of this study was to investigate in the residence and the income choice attributes and usage pattern of Bakery Product Purchasers. The findings of survey showed that in general characteristics of respondents, Out of the total 1,235 people, 59.6% of them were women, 40.4% of them were men, so the number of females was slightly higher than that of males. On the matter of bakery purchase attributes, in the case of food life 'health-interest type' was the most popular with 40.0%. In residential areas, people living in large cities received 35.8% of the 'taste-interest type', while people living in small and medium sized cities received 45.4% of the 'health-interest type'(p<0.001), the higher the income, the more interested in your health(p<0.001). When purchasing bakery products, consumers had different importance factors such as taste 67.1%, nutrition 13.7%, price 7.8%, in residential areas was a significant difference(p<0.01). In bakery-using type, franchise bakery was 71.1%, window bakery 14.6%, in-store bakery 8.4%.

CS is one of the major concerns of managers in the world because it is well known to be a key medium construct for firms' superior outcome. One of the major agents for CS management is retailers. Firms try to manage not only employees but also retailers to promote CS behaviors. And so diverse incentives are used to promote their CS behaviors under diverse channel setting such as multi-channel. However in spite of the rising needs there has been scarce studies on the optimal incentive structure for a manufacturer to offer competing retailers at the multi-channel. In this paper, we try to find better way for a manufacturer to promote the competing retailers' CS behaviors. We investigated how to promote the retailers' CS behavior via game-theoretic modeling. Especially, we focus on the possible incentive, CS bonus type reward introduced in the studies of Hauser, Simester, and Wernerfelt(1994) and Chu and Desai(1995). We build up a multi stage complete information game and derive a subgame perfect equilibrium using backward induction. Stages of the game are as following. (Stage 1) Manufacturer sets wholesale price(w) and CS bonus($\eta$). (Stage 2) Both retailers in competition set CS effort level($e_i$) and retail price($p_i$) simultaneously. (Stage 3) Consumers make purchasing decisions based on the manufacturer's initial reputation and retailers' CS efforts.

The survey was conducted to investigate the consumption aspects of commercial kimchi and the future pattern of kimchi consumption. The college students(473) were randomly selected from six universities in Taejon. Ninety seven percent of students had taken the commercial kimchi. They chose kimchi manufactured by the famous company(62.4%), merchant in market(16.9%), and agricultural corporation(14.4%). In purchasing the commercial kimchi, qualty(76.0%) was considered as the most important factor and then price(13.1%), brand name(5.1%). The main reason for disliking commercial kimchi was indicated as 'different taste from home-made' by the male and 'additives added in kimchi' by the female(p<0.01). The maintenance of aging condition was believed the most essential factor to increase the consumption of commercial kimchi. Two thirds of the subjects anticipated to take home-made kimchi after marriage. Half of them replied to want to take kimchi made by traditional method, even though to buy the sauce for kimchi-making sold in market. More female students were willing to purcase the sauce for kimchi-making than the male(p<0.01).

The lighting devices using organic light emitting diodes (OLEDs) are actively researched because of the various advantages such as high power efficiency and 2-dimensitonal lighting emitting. To commercialize those OLED lighting devices, the manufacturing cost must be downed to comparable price with conventional light sources. Here, we demonstrate a reverse gravure-offset or gravure off-set printed metal electrode for the auxiliary electrode for OLED lighting devices. For the fabricated OLED's auxiliary electrode, we used Ag nano-paste and printed metal grid structure with a line width and spacing of several ten and hundred micrometer by using gravure-offset printing. In the end the printing metal grid pattern are successfully achieved by optimization of various experimental conditions such as printing pressure, printing speed and printing delay time.

In this paper, we presented a simple hologram recording set for learners to broaden their program choices and experience holographic techniques with lifelong education programs. In order to obtain quality 3D images, the quality of light sources and recording mediums, which are the main elements of hologram recording, must be good. In addition, due to the characteristics of the hologram, the ambient vibrations shall be minimized for accurate interference pattern recording. The simple hologram recording set presented in this paper has not significantly restricted in space and location, and anyone can easily experience it at a reasonable price compared to the existing hologram production method. Also, it can make two different type of hologram (transmission and reflection) for providing easy access to recording and reconstruction of the hologram. Experiments have shown that holographic manufacturing practices are a very useful way to educate the public on optics and photonics technologies.
