Objective:To investigate the current status of prescription drugs in Oriental medical institutes and to draw up a future plan for the revitalization of Oriental medical health insurance, this survey has been performed. Method:The survey has been made with 321 doctors working at Oriental medical institutes in Daegu and Kyungbuk areas for a period of 3 month from June 1, 2010 until September 1, 2010. Result:1. When it comes to the current status of the use of herbal drugs in Oriental Health insurance, most of doctors surveyed prescribe insurance drugs, and they prescribe insurance drugs to patients, who are less than 20% of total patients visiting their clinics. 2. The awareness of Herbal Health Care Drugs is investigated. When it comes to the understanding of the difference between insurance drugs(powder type drugs) and granular type drugs, doctors admit that they differ only in one aspect, whether or not their being covered by health insurance. Based on the survey results on the understanding of insurance coverage of granular type drugs, doctors, even though they long for granular type drugs to be accepted as insurance drugs, are worrying whether the number of outpatients might dwindle due to increased insurance co-payments. They also point out that the biggest obstacles in the expansion of the granular type drugs as insurance drugs are the lack of understanding of the government and the objection of the Health Insurance Review and Assesment service (HIRA) for fear of increased insurance claims. 3. Upon investigation on Oriental medicine doctors`` understandings of herbal pharmaceutical industry, it is found that doctors`` responses on pharmaceutical industry are not all positive ones (``new product development and neglect of R&D infrastructure`` and ``smallness of industry``). When it is investigated what area needs the greatest improvement in herbal pharmaceutical industry, ``securing sufficient capital, good manufacturing, and strengthening quality control``, is the highest. 4. When it is asked what are the most needed in order to improve herbal health insurance medicine, responses such as ``the increase in the accessibility to and the utilization of Oriental medical clinics through the diversification of the means of prescriptions``, ``the improvement of insurance benefits(cap adjustments)``, ``increase the proportion of high quality medicinal plants``, ``the ceiling of co-payments(deductible) at 20,000 won or more``, ``expansion of the choices of formulations``, ``formulational expansions of tablets and pills``, and finally ``admittance and expansion of granular type drug as insurance drug`` are the highest. 5. Upon investigating the general characteristics of the current status of the usage of Oriental health care herbal drugs, the followings are observed. First, the frequency of use of health insurance drugs by the doctors who use health insurance with general characteristics shows similar differences in case of total monthly sales amount (p<0.001), average number of daily patients (p<0.05). Secondly, as to the willingness of the expanded usage of insurance drugs, similar differences are observed in case of total monthly sales amount (p<0.05). 6. Upon investigating the general characteristics of the perception of Herbal health care drugs, the followings are observed. First, inspecting general characteristics and insurance claims due to increased co-payments(deductible amount) reveals similar differences in case of working period (p<0.01) and in case of total monthly sales amount (p <0.01). Secondly, inspecting general characteristics and the obstacles that hinder granular type drugs from being accepted as health care insurance drugs shows similar differences in case of working period (p<0.05). 7. Upon investigating the general characteristics of the understanding of Oriental Herbal pharmaceutical companies, the followings are observed. First, opinions on the general characteristics of pharmaceutical companies, when examined with variance analysis, shows similar differences in case of total monthly sales amount (p<0.05). Secondly, when opinions are examined on general characteristics and the problems of herbal pharmaceutical companies, similar differences are found in case of working period (p<0.01) and in case of total monthly sales amount (p<0.001). Lastly, opinions on the general characteristics and reforms of pharmaceutical companies, similar differences are observed in case of working period (p<0.001). 8. Upon investigating the general characteristics of the improvement of insurance Herbal drugs, the followings are observed. First, regarding general characteristics and insurance benefits, similar differences are observed in case of working period (p<0.05), in case of total monthly sales amount (p<0.05), and in case of average number of daily patients (p<0.01). Secondly, opinions on the general characteristics and the needs for the improvement of Herbal insurance drugs are examined in 5 different aspects, which are the approval of granular type drugs as insurance drugs, the expanded practices of the number of prescription insurance drugs, the needs of a variety of formulations, the needs of TFT of which numbers of Oriental medical doctors are members for the revision of the existing system, and the needs of adjusting the current ceiling of the fixed amount and the fixed rate. When processed by the analysis of variance, the results show similar differences in case of average number of daily patients (p<0.01). Conclusion:From the results of this study the first measures to take are, to reform overall insurance benefit system, including insurance co-payment system(fixed rate cap adjustment), to expand the number of the herbal drugs to be prescribed matching with insurance benefit accordingly, and to revitalize herbal medicine insurance system through the change of various formulations. In addition, it is recommended to improve the effectiveness of herbal medicine by making plans to enhance the efficacy of herbal medicine and by enabling small pharmaceutical companies to outgrow themselves.

본 논문에서는 축삭의 전도 현상을 분석하기 위해서 축삭을 전기전도 모델로 만든 후 여기에 키르히호프의 전류법칙과 전압법칙을 적용한 등가회로를 구성하였다. 축삭의 미세거리 변화에 의한 전위의 거동을 분석하기 위하여 축삭의 각종 파라미터를 구하였다. 검토결과에 의하면 무수신경인 경우 직경을 미지수로 하여 인체의 파라미터를 이용하면 그 속도는 직경의 제곱근에 비례한다. 한편 유수신경인 경우는 그 속도가 직경에 직접적으로 비례한다. 미엘린이 없는 막과는 달리 미엘린껍질의 전도는 전압과 무관하므로 이러한 막 양단의 Hodgkin-Huxley 형 전도모델이 매우 정교하지는 않다. I made the axon to the electrical transmission model and then constructed electrical equivalent model using Kirhhoff`s current law and voltage law in this paper. I calculated various axon parameters in order to analyze the electrical potential hehavior versus minute distance chang of axon. The transmission velocity of unmyelinated nerve is proportional to square root of axon diameter, while that of myelinated nerve is directly proportional to its diameter. Because the transmission of myelin sheath is independent of voltage unlike unmyelinated sheath, the Hodgkin-Huxley model across the membrane is not so precise.

This study investigates the modernization process of the government managing housing in Korea from 1910 to the early 1970’s based on the discourse of Le Corbusier"s taylorization, which presumes standardization and industrialization. Through the case study, we found a tendency of standardization and industrialization of building components in Korean modern housing based on the separation of themselves, for example from a united wall to a separated column, interior material, covering. Spatial taylorization can also be recognized based on the achievement of relatively open plan due to the change of structure system. Standardization of space is recognized in two ways. One is to add standardized spatial units to compose a house. The other is to divide a standardized big space to form a house. Meanwhile, open-ended system and closed system, the two typical construction methods of the modern architecture, were both developed but especially in the construction of houses the closed system settled successfully compared to the open-ended system due to the support of government. Above-mentioned features of Government Managing Housing in Korea shared common characteristics with Western Modern Architecture but also had unique features. This is due to a specific circumstance of Korea during modernization.

A method to provide shared housing with minimum dwelling units was planned by specialists in the West in the early 20th century and affected government managing apartment houses in Korea. The tendency to make shared housing can be summarized as two steps : First, minimum dwelling units are planned. Integration of spaces which have similar programs and commercialization of making food are related features of minimum dwelling units. Second, specific programs which cannot be put into the units due to their small size are planned as shared space. Shared housing holds a potential to enhance a communalized way of living. The government managing apartment houses in Korea from the 1960’s to the early 1970’s were equipped with minimum dwelling units. Commercialization of making food was attempted but the culture of making traditional Korean sauces and storing them in the house did not easily change. This cultural tendency triggered unique plans of Korean apartment houses which enables dwellers to store traditional sauces. Meanwhile, lavatory, corridor and courtyard were shared but planning of these shared space did not have an intention to enhance the communalized way of living. On the contrary, a tendency of pursuing high degree of privacy was major preference of dwellers in these shared housing and this affected to the way of planning apartment houses after the 1970’s.

Under the demographic pressure of Seoul in 1930s and 40s, most of residential areas in Seoul were developed by means of the Land Readjustment Project(LRP, 1937~42) and the Residential Complex Project(RCP, 1940~44) planned by the Japanese Colonists from the late 1930’s to the early 1940’s. Meanwhile, the Neighborhood Unit Principle(NUP) of C.A.Perry(1929) have been widely known to have affected the plan of residential areas in Seoul. There are a few studies on NUP but the starting point when NUP affected is not clearly agreed. In this study, documents of conceptual debate on the method of LRP and related materials containing the plan of the public parks in Seoul published from the late 1920’s to the late 1930’s are analyzed and compared. Furthermore, three areas of LRP planned in the late 1930’s and three areas of RCP planned after 1940 are also analyzed based on NUP and compared with each other. The analysis and comparison of the related documents shows that the NUP began to affect the related discussions from the late 1920’s. This means that experts of urban planning at that time might have a similar way of thinking at least from the late 1920’s. The analysis and comparison of the three areas of LRP and RCP shows that NUP started to affect from the late 1930’s and arrangement of public institution was the main focus of the application of NUP. Based on these works, on the contrary to a former study, it can be said that the NUP affected the LRP as early as in the second half of 1930s.

Objectives: The purpose of this study was to examine the prescription intention of Korean medicine doctors on botanical drug. Methods: The subjects in this study were 340 Korean medicine doctors in Korean medical institutions, on whom a survey was conducted from July 1 to August 31, 2014. Results: The factors that affected the prescription decision making of the Korean medicine doctors were drug superiority, level of Interest, Recognition, marketing of sales associates of pharmaceutical companies and satisfaction with information provided by those companies. When the internal consistency of the variables was measured, that was above 0.8. The influential factors had a great explain ability when the general characteristics of the subjects were adjusted(prescription intention : 38.1%). In contrast, the explainability of the factors was low when only their general characteristics were inputted(prescription intention : 8.0%). Among the five factors, satisfaction with marketing and awareness didn``t exert a significant influence on prescription intention. Conclusions: Accordingly, well-planned education and promotion efforts are required to encourage Korean medicine doctors to put more prescription intention in botanical drug. This study had some limitations : First, the subjects were selected in a manner to allow for the convenience of this researcher, and the findings might not be generalizable. Second, there was a problem with the time for the study in that there were quite fierce disputes on botanical drug at that time. Third, the majority of the subjects run their own hospitals, and the number of them was small. So it``s not possible for them to represent every Korean medicine doctor.

우산 빗물 받이용 일회용 비닐봉투를 실질적으로 대체할 수 있도록 Air Jet를 이용한 우산의 빗물을 제거 장치를 설계하였다. 우산의 크기와 다양한 모양을 모두 사용 가능하도록 Open형 거치대에 우산의 지지대를 올려놓으면 작동되는 Touch형 스위치를 통해 작동이 용이하도록 설계하였다. 이를 위해 Water Droplet이나 Water Film에 작용하는 외력을 분석하였다. 유동장의 특성은 기본 CFD tool인 Discovery Live를 이용하여 공기 유동장 해석을 수행하였다. Air Jet Reflector는 사용자에게 물방울이 튀기지 않고 반사시키도록 설계하였으며, 그 밖에 배수구, 이동용 바퀴 등을 기본 설계안으로부터 수정하여 보완하였다. 이를 통해 친환경적 Air Jet 우산 빗물 제거기를 구현하였다. 공공 기관이 다수가 사용하는 상업 시설의 입구에 설치하면 1회용 우산 빗물 받이용 비닐의 사용을 획기적으로 감소시킬 수 있다. To practically replace disposable plastic bags for receiving rainwater from umbrellas, a rainwater removal system was designed by using an air jet blower. It was designed to be easy to operate through the touch type switch which was operated by placing the support of the umbrella on the open type holder so that the size and various shapes of the umbrella can be used. For this purpose, the external force acting on the water droplet or water film was analyzed. The flow field was analyzed using the Discovery Live, a basic CFD tool. Air Jet Reflector was designed to reflect water droplets to users, and drainage, wheels, etc. have been modified from the basic design. Through this, an eco-friendly air jet umbrella rain water removal system was developed. When installed at the entrance of commercial facilities used by many public institutions, the use of disposable umbrella rain gowns can be significantly reduced.
