This study is to analyze the effect of neighborhood commercial facilities on the homeproduction activities and the family expenditure(or household work time). For this purpose. data are collected by using questionnaires distributed to 522 housewives in Seoul. The results shows that in the highly goods-intensive environment. the way of homeproduction is goods-intensive. Market dependence of the family is affected by homeproduction predisposition. income. and husband's job. Household work dependence of the .family is affected by neighborhood facility environment. family type. income. and house value. Low home production supportability is apparent in the high family income. full-time housewives and low job status of housewife. On the other hand. high homeproduction supportability is apparent in the moderate income and high job status of housewife. As a result. housewives have much time and money resourses are not well supported by the neighborhood facility environment.

A total of 93 specimens of Astroconger myriaster were purchased from the Chungmu fishery market at the south sea area during the period from October 1 to November 25, 1996. Specimens were examined for the infection status with larvae anisakid. Anisakid larvae were collected from viscera, muscle, omenturn and liver. Eight hundred four larval anisakids sorted from 93 specimens of A. myriaster ranged from 9.0 to 26.5mm in their body length. They were classified based on morphological and morphometric observations as follows Anisakis type 1 larvae (465 larvae, 57.8%: positive rate), Contracaecum type D(129, 16.0%), Contracaecum type A(90, 11.2%), Anisakis type 11(60, 7.5%), Phapidascaris(3, 0.4%) and unknown type(57, 7.1%).

INDUSTRIAL DESIGN(1.D) has been recognized as an independent subject for 30 years 10 KOREA and 70 years in the worldwide. Though the beginning of the 1.D is extended to the commercialization of the art, history of 1.D is still 150 years, and very short compared to the those of other subject. The scientific identity of 1.D has to be established to prepare the role of 1.0 for the information society and industrial society of the 21 century. 1.D contains the essence such as integrated and $$\mu$titude character and two lineaments( Analytic science and Synthetic science-objective and subjective) 1.D has undergone confusion and fallacy in society and educational system. To develop achieve the goal of design education and to the competItIve design country in the world market, the scientific status of I.O has to be established as a integrated and independent subject. This study generally reviewed 1.0 to find the essence and scientific status of subject to determine the direction foward the next century in the view of intellectual structure and system.

Objectives : In this report, we were studied the current status and future about cultivation of medicinal plants in Japan. Methods : To analysis the management and production of medicinal crops in Japan, variation of importation and cultivation of four medicinal crops such as Angelica acutiloba Kitagawa, Cnidium officinale Makino, Paeonia lactiflora Pallas and Rehmannia glutinosa Liboschitz var. purpurea Makino within 22 years ($1981{\sim}2002$) were investigated. Also we analyzed the herbal drug market in Japan using literature. Results : In the results, cultivated area and amount of Angelica acutiloba Kitagawa and Paeonia lactiflora Pallas reduced more than 50% within 22 years ($1981{\sim}2002$). Production decrease of medicinal crops is alloting through contract production in China. The cultivation of Rehmannia glutinosa Liboschitz var. purpurea Makino is enforcing minimum procluction for seed security. Conclusion : We hope that this report stimulates research to investigate for the establishment of cultural practices in Korea.

In this paper, we are looking for requirements of software, hardware and application for use in network-based robots and also directions in building standardization and research activities by reviewing technical status of the robot industries developing robots. The questions are including awareness of RUPI(Robot Unifies Platform Initiative) activities, target market and applications, hardware specifications, software development technologies, and HRI(Human Robot Interaction). The RUPI committee creates standard and drives implementation software for network-based robots through industrial requirements as like of the results. Many robots have been developed and launched services based on RUPI 1.0 standards. Based on this achievement we are expanding RUPI standard to include thin and thick client robots. The results also show that which one is important and urgent technology in the sense of industrial robotic business.

Historically, the decision to perform a hemiarthroplasty (HHR) versus a total shoulder arthroplasty (TSA) is based on the status of the glenoid and the status of the soft tissues (rotator cuff). In disease processes where the glenoid articular cartilage is relatively well preserved such as avascular necrosis and complex proximal humerus fractures, most orthopaedists recommend performing a HHR while preserving the native glenoid articular surface. At the other end of the spectrum, if the glenoid has excessive bone loss or is unreconstructible, a HHR is the preferred procedure. In patients who have deficient so(t-tissues (rotator cuff) such as rotator cuff tear arthropathy and, occasionally, rheumatoid arthritis, a HHR is the procedure of choice. The indications for HHR in osteoarthritis remain somewhat controversial. There is mounting evidence that performing a HHR for osteoarthritis is inferior to TSA. Recent developments, or 'third generation techniques and materials', in shoulder arthroplasty are expected to improve the longevity of TSA, particularly the glenoid component. In addition, newer designs of reverse-ball prostheses are entering the market with promising early results in patients with deficient rotator cuff mechanisms.

This is a brief review and discussion for present status and prospects of quality evaluation in medicinal plants as oriental medicine materials (OMM). Quality in medicinal plants could be defined as the combination of origin, external appearance, effectiveness and safety, and be evaluated by plant taxonomic, morphological, physiochemical and biological methods. For high-quality improvement and standardization of OMM, medicinal plants should be produced through using proper species or good variety and standard cultivation method in suitable cultivation area. Standardizing of quality means to meet with minimum qualifying criteria of OMM in the market while improving of quality to be over standard quality of medicinal piano in production. For making new high quality and standardized products, we need to keep standard field plants, standard OMM, standard plant specimen, and standard compounds. Researchers and administration have to study and propose the quality factors and their evaluating techniques and criteria, so high-quality and standardized produce of medicinal plane could be produced and distributed under the control of the relevant regulations, and would be contributed to increasing of national health.

This paper focuses on the concept of :"politicization of household labor" to the resolution of houework-related problems which are the products of household work and the women's status. the major discussions of this framework can be summarized as follows: First the policy problems of household labor is that the segregation of market labor and household labor public and private sphere and sex-role affects value of household labor and status of women. Second policy proposals on household labor is related to specific existing policy(family policy women's policy). Third Policy purposes are family welfare and women welfare a symmetry of family and work. Thus policy needs takes concrete shape and policy indicator of evaluing and and policy indicator of supporting. Ultimately it is direct to evaluate the quality of family living.

Organic light-emitting diodes (OLEDs) have already been commercialized for the mobile-phone display, TV, and lighting panels. Even though the OLED display for the mobile phones is now considered as the main stream display for the application, the OLED TV and lighting panels are having difficulty in their market due to their high prices despite the better performance to the competitors. In recent years, roll-to-roll production of the OLED has begun to be examined, and this method is opening a way to solve the high price problem. In this article, we introduce several important processes for roll-to-roll production of OLED and explain the development status to date.
