A study on the correlation between four GCM types and Dam and Bangkwang types of Hyungsang medicine comes to the following conclusions : GCM I type is closely related to Bangkwang type in Hyungsang medicine. GCM II type corresponds to Dam type. In terms of obesity and emaciation, GCM I type is related to obesity and GCM II type to emaciation. In terms of Right and Left, GCM I type is more active in Left, GCM II type in Right. In terms of movement, GCM I and II types are kinetic and GCM III and IV types are static. In terms of Front and Back, the disease of GCM I type usually appears on Back but the treatment starts on Front. In GCM II type, disease mainly occurs on Front but the treatment starts on Back. GCM I type is susceptible to an alimentary disease and constitutionally predisposed to damp-phlegm in Hyungsang medicine. GCM II type is easily affected by a circulatory illness and very vulnerable to heat with blood deficiency and depression and stagnation of Ki.

Plasma actuator makes parallel flow on the wall surface by the interaction between plasma and neutral air particles. Dielectric barrier discharge (DBD) plasma actuator is widely studied as one type of plasma actuators, which consists of one electrode exposed to the environmental gas and the other encapsulated by a dielectric material. This paper is experimentally focused on the performance of DBD plasma actuator mounted on a flat plate, which depends on kinds of the electrode materials, their thicknesses and the supplied voltage including its frequency. We measured the velocity magnitudes of the induced flow by a stagnation probe as a performance parameter of the plasma actuators. The velocity profiles of the flow induced by the plasma actuators are similar in all measurement cases. The magnitude of the induced velocity is strongly influenced by the thickness of the electrodes and the frequency of the input voltage. The performance of DBD plasma actuators is related to the electric properties of the electrode materials such as the ionization energy and the electrical resistivity.

맥동연소의 비정상 점화현상을 연구하기 위하여 이론적인 해석을 수행하였다. 맥동연소에서는 연소기의 양쪽에서 유입되는 고온의 연소가스와 미연 혼합가스가 연소실 내부에서 충돌하여 정체면을 형성하며 유동변형율이 임계 값 이하가 될 때까지 점화가 억제된다. 본 연구에서는 유동의 유동변형율의 변화에 대한 점화현상의 반응을 연구하기 위하여 활성화 에너지 점근법과 비가역 1단계 화학반응을 이용하였다. 또한 유동에 의한 유동변형율은 두 가지 요인에 의하여 발생하는 것으로 모델링 하였는데, 비정상 유동에 의한 평균 유동변형율과 난류에 의하여 유도되는 유동변형율이 그것이다. 해석 결과에 의하면, 맥동연소에서는 잘 정의된 점화지연이 존재하며, 점화 또는 소염의 발생 여부는 Damkohler 수에 의하여 거의 결정된다.

The laver has been cultivated long time ago in Korea. And traditional production system was changed to new system about 30 years ago. The new production system is understood the specialization of laver products, that is, originally individual fishery households made final laver products from raw cultured laver in sea working to dry working in land, but the new system was separated raw laver production in sea and dry laver production, which made final dry laver products by purchase the raw laver in land. This change has been increased laver production, 10 billion sheets in 2000's from 5 billion sheets in 1980's. And rapid production increase gave rise to some troubles on laver industry that is a serious drop in real laver prices, discord structure between raw laver producer and dry laver producer, stagnation of laver consumption, etc. Now Korea is the best laver production country together with Japan in world. Then we have to consider some schemes for the sustainable development of laver industry. One of such schemes is export enlargement of laver against world. The consumption of laver has been globally increased in recent. The other is the grading test problem of dry laver. Because the rapid increase of laver production caused to drop laver quality. Then we seriously have to consider the grading test of dry laver for high level quality production.

A numerical study of heat and mass transfer has been carried out for a frost formation process on a circular cylinder in a cross flow including the effect of buoyancy. Studies include cases of low and high Reynolds number flows. The effect of normal velocity at the surface which is produced due to mass transfer was included in the analysis as well as heat transfer contribution generated due to mass transfer. Variations of heat transfer and frost growth both in time and in the circumferential direction have been obtained for various buoyancy parameters. The effect of flow directions(identical or opposite directions to the gravity) has been studied to yield different frost growth. Our results have been compared with existing experimental data and are in good agreement. Buoyancy analyses for a high Reynolds number flow agree with full numerical solutions for the case of having the same flow direction as gravity. However, for the opposite direction case, the boundary layer analyses would not be applicable to predict frost growth except the region near the stagnation point.

In order to have better understanding of the concept and meaning of soundscape, it is very important to consider entirely the objectives, activities, historical development processes and accomplishments of world soundscape project leading by R. Murray Schafer. Therefore, the ultimate purpose of this study is to inquire into the concrete development processes and practical activities of the soundscape in order to correspond to Schafer's conception of a tuning of the world. The establishment of WSP is based on noise pollution, listening attitudes and noisy music. Schafer formulated 5 types of item as a target, and wrote down concrete activities to achieve the goals. Especially, he devised the conceptual, educational, political and social strategies as the practical strategies of WSP. It is obtained various products by the activities of WSP from the planning starting year in 1969 to the stagnation period in 1979. That is, there are the social survey on noise-vancouver 1969, the book of noise, Okeanos, a study of community noise by-laws in canada 1972, the music of the environment, the vancouver soundscape, european sound diary, five village soundscapes, handbook for acoustic ecology and so on. The research activities of WSP arouse inspiration in many people interested in sound. Specially, it is emphasized the importance of increasing for their social roles in order to more actively improve and create the quality of sound environment. Also, it shows us the directions on how to lead our furture sound.

Objectives The purpose of this study is to understand formation courses of the ten types of LBP (十種腰痛) in Korean medicine through reviewing classic literatures. Methods We summarized sentences describing syndrome differentiation of LBP directly in Uibujeonrok (醫部全錄) and Donguibogam (東醫寶鑑), and then organized similarities and differences among diagnostic factors described in the classic literatures. Results In most of the classics LBP was classified according to the cause but the causes varied depending on the classic literatures. Cheonkeumbang (千金方) tried to suggest a reasonable classification of LBP in a relatively early age. In Dangyesimbeop (丹溪心法) the causes of LBP were divided into 6 factors; qi movement stagnation (氣鬱), dampness-heat (濕熱), kidney deficiency (腎虛), static blood (瘀血), sprain (挫閃) and phlegm accumulation (積痰). It had a lot of influence on the classic literatures published later. Donguibogam was also influenced by the Dangyesimbeop and the ten types of LBP in Donguibogam was similar to the information on the classification shown in Uihakipmun (醫學入門) and Uijongpildok (醫宗必讀). Conclusions We verified universality of the ten types of LBP; kidney deficiency, phlegm-retained fluid (痰飮), food accumulation (食積), sprain, static blood, wind (風), cold (寒), dampness (濕), dampness-heat and qi (氣).

Determination of geometric design parameters of a second-throat type annual supersonic ejector is described. Tested geometric parameters were primary nozzle area ratio, cross-sectional area of second-throat, L/D ratio of second-throat and primary flow injection angle. Varying these four geometric parameters, we build a test matrix made of 81 test conditions, and experimental apparatus was fabricated to accommodate them. For each test condition, the stagnation pressure of primary flow and the static pressure of the secondary flow were measured simultaneously along with their transition to steady operation and finally to unstarting condition. Comparing the performance curve of every case focused on starting pressure, the unstarting pressure and the minimum secondary pressure, we could derive correlations that the parameters have on the performance of the ejector and presented the optimal design method of the ejector. Additional experiments were carried out to find effects of temperature and mass flow rate of the secondary flow.
