Objectives: The aim of this survey was to investigate utilization, intended use, problems with and demand for medical devices by surveying members of the traditional Korean medical society. Methods: We distributed questionnaires to 13,957 traditional Korean medical doctors via e-mail, and received replies from 1,225. The questionnaire consisted of 4 multiple-choice questions for survey respondent information, 8 multiple-choice questions about the status of medical devices utilizing, and a short answer question about the demand for medical devices. Results: Use of medical devices in traditional Korean medical clinics is common. Diagnostic medical devices are mainly used to assess the patient's condition and to establish a close rapport with clients. In case of therapeutic medical devices, they are usually used for secondary treatment. Issues with traditional Korean medical devices currently in use were ineligibility for national health insurance, low reliability, uncertain validity, and high price. In development of traditional Korean medical equipment, the need for diagnostic medical devices was greater than for therapeutic, and the need for the recording and analysis of medical image data and visualization of medical information was great. Conclusions: There is growing demand for facilitating the development and commercialization of traditional Korean medical devices. To satisfy this demand, research on evaluation indicators that reflect functional and structural clinical information and how to clinically assess the indicators should proceed.

The purpose of the study was to provide the informations about the economic status of elderly households. Utilizing the 1996 national household data, economic status was investigated by the components of two financial statements: the income and expense statement and the balance sheet statement. Thus it included incomes, consumption, propensity to consume, savings(financial assets), debt amount and net-savings. The elderly households were compared with the nonelderly households. The subgroups of the elderly were also compared. They were divided based on the employment status of the head and household composition. The results showed that the economic status of the elderly was worse compared to the nonelderly. There were also variations among the subgroups of the elderly households. In general, the economic status of retired households and single households were worse than those of employed households and of the households composed of couple and the elderly living with children.

This study has investigated the status of utilizing 3D printing in fashion field in order to keep up with the trend for 3D printing technology to be realized in all industries so that the materials and the modeling modes may be figured out. The following is the findings. The materials used most in 3D printing in fashion field are PA, PLA, TPU, multi-material, ABS and metal. PA, TPU and Multi-material have so much excellent flexibility and strength that they are widely used for garment, shoes and such fashion items as bags. But PLA, ABS and metal are scarcely used for garment because PLA is easily biodegradable in the air, ABS generates harmful gas in the process of manufacture and metal is not flexible, while all of these three are partly used for shoes and accessories. The modeling modes mainly applied for 3D printing in fashion field are SLS, SLA, FDM and Polyjet. SLS, which is of a powder-spraying method, is used for making 3D textile seen just like knitting. Polyjet method, which has higher accuracy and excellent flexibility, can be used for expressing diverse colors, and accordingly it is used a lot for high-quality garment, while SLA and FDM method are found to be mostly used for manufacturing shoes and accessories rather than for making garment because they are easily shrunk to result in deformation.
