  • In Soft ground of south-western coast of our country necessity of marine indutrial complex and container facility has been remarkable. Site construction for habor facility is one of the most urgent problems. Consolidation of dredged fill has become important task. In addition, volume change of dredged fill should be examined carefully. This study dealt with consolidation of dredged fill by PCDDF and in order to secure trafficability of heavy equipment for surface treatment should be studied.

  • Liquid ammonia treatment known as the most effective Wood plasticization method, was applied to two typical domestic species, Pinus densiflora, Castanea crenata. Small specimens of 30mm width, 300mm length and two thicknesses, 5 or 10mm, were used. For 5mm thick Specimens, Pinus densiflora was quite well plasticized iker 4 hour liquid ammonia treatment, while Castanea crenata was not plasticized even after 4 hour treatment. Specimens of 10mm thick Pinus densiflora were hardly plasticized, but those with kerfs were bent somewhat easily, With the increase of liquid ammonia treatment time the thermal conductivity of Pinus densiflora increased, while that of Castanea crenata didn't Presteaming before liquid ammonia treatment didn't improve the plasticization of both species.

  • In this paper, we proposed eyeglass type periorbital wrinkle treatment device for reducing and improving periorbital wrinkles using near infrared LED of 850nm wavelength and galvanic current. The proposed periorbital wrinkle treatment device is equipped with a control system based on F-PCB. It consists of eight near-infrared LEDs and four indicator LEDs for treatment of right and left periorbital wrinkles. The eyeglass frame is coated with conductive material, so galvanic current can flow to the skin of periorbital wrinkle contacted to it. One male adult in the mid-40s was allowed to use the device for 10 minutes every day for 4 weeks. After 4 weeks, image analysis using optical equipment for measuring wrinkles indicated that wrinkle indexes were reduced.

  • High reliability thin film transistors are important factors for next-generation displays. The reliability of transparent a-IGZO semiconductors is being actively studied for display applications. A plasma treatment can fill the oxygen vacancies in the channel layer and the channel layer/insulating layer interface so that the device can work stably under a bias voltage. This paper studies the effect of plasma treatment on the performance of a-IGZO TFT devices. The influence of different plasma gases on the electrical parameters of device and its working reliability are reviewed. The article mentions argon, fluorine, hydrogen and several ways of processing in the atmosphere. Among these methods, F (fluorine) plasma treatment can maximize equipment reliability. It is expected that the presented results will form a basis for further research to improve the reliability of a-IGZO TFT.

  • In adult patients with dental phobia, dental treatment may be difficult, or may not be possible. Depending on the level of fear or anxiety, non-pharmacological or pharmacological behavior management techniques are used in the dental treatment of such patients. Among the pharmacological behavior management techniques, minimal sedation, that is, the lowest depth of sedation, can be easily obtained in adult patients using oral sedatives, does not require special equipment or tools, and does not affect ventilatory and cardiovascular function. Diazepam is an anxiolytic drug belonging to the benzodiazepine family that, in addition to relieving anxiety, produces muscle relaxation, and is a representative drug used in adult patients with fear of dental treatment. Herein, we report the case of a 50-year-old woman with severe dental fear who successfully underwent long-term dental treatment in approximately 20 visits with minimal sedation using oral diazepam. In addition, we reviewed the considerations for the use of benzodiazepines for minimal sedation.

  • The objective of this study is to identify the difference in attitude toward medical care between patients who visited a university hospital or an oriental medical hospital of oriental medical college, and physicians who engaged in the same hospitals. The subjects of this study were 397 cases who agreed to respond the prepared questionnaire, including 288 patients(146 university hospital utilizers and 142 utilzers for an oriental medical hospital) and 109 physicians(76 physicians and 33 oriental medical doctors). The attitude toward medical care was measured by the structured questionnaire developed for this study, which had high validity and reliability according to factor analysis, item discriminant validity, and Cronbach's $\alpha$ coefficients. On the criteria of mean value of care and cure score, the attitude toward medical care was classified into 4 groups encompassing a group with dependent attitude on medical care, a group with skeptical attitude toward it, a group with cure-oriented attitude, and a group with care-preferred attitude. The results of chi-square test, discriminant analysis, and logistic regression analysis were as follows; patients who visited a univisity hospital, patients who visited an oriental hospital, physicians, and oriental medical doctors included in the group with dependent attitude, the group with cure-oriented attitude, the group with skeptical attitude, and the group with care-preferred attitude, retrospectively. Among the subdomains of care and cure domains, which classified in reference to the result of factor analysis on pilot study, those that patients ranked more importantly than physicians were 'the importance of medical equipment for diagnosis and treatment', 'authority of physician, 'aggressiveness of treatment', 'information giving', 'personal interest' in the case of western medicine. In the case of oriental medicine, those were 'the importance of equipment for diagnosis and treatment', 'aggressiveness of treatment', 'amenities and accessibility', 'coordination of medical staff'. Both physicans and patients put the subdomain, 'physicians' medical knowledge and skillfulness' on the highest rank. The differences in ranking the important attributes of medical care between patients and physicians were apparent in the area of an 'importance of medical equipment for diagnosis and treatment' and so on. It meant that patient had over-expectation on medical care and suggested that the policy on demanad side such as the developement and dissemination of an evidence-based recommendation protocol for health care consumers might be important in Korea. In addition, regarding the attitude of physicians, during the medical education and training it may be neccessary to emphasize the aspect of 'care' of medical care rather than 'cure'. In planning on heath care delivery system, it should be considered that there is a difference in the attitude toward medical care between western medicine and oriental medicine as well as between health care providers and consumers. We expect that more valid measurement tool be developed in this area, which may be major limitation of this study and that this kind of research be expanded into the non-academic settings.
