This thesis is to study the original form of Buckles of our country in ancient times On the upper garment bound the leather belts that was hanged a hook that shaped of animal form at the end. The background of Buckles was originated from those northern mounted normadic groups which was Scythe style costume culture. In Korea through the antique records and tombs bequests the styles of Buckles was divided into three groups horse-shaped tiger-shaped bar-shaped Buckle. These styles were influened by scythe style and developed greatly and trasmitted to Japan.

This study aims at alalyzing the circulation process, merchandising system of Mosi(Korean traditional garment material), and accessing the way of interior design of Mosi market. There are three kinds of garment material of Mosi such as Pilmosi, Gootmosi, Taemosi classified by manufacturing process. At Mosi market, these three materials are sold in due sequence. Mosi market needs three space zones such as Mosi market space, inspecting space of Mosi and resting place, and these three spaces have strong interrelationship, so designer should plan not to disterb the moving flow. In the Mosi market space there should be divided by three zones such as Pilmosi marketing place, Gootmosi marketing place, and Taemosi marketing place in due sequence. The furniture of Mosi market place divided two kinds such as furniture for Pilmosi and that of Gootmosi or Taemosi. The proper form of furniture for Pilmosi is circular arc bar counter and that for Gootmosi or Taemosi is low rectangular table.

The processes of vegetation development and interspecific association were studied as a part of a successional study in the sand bars at the Nadgdong River estuary in Korea. The major pioneer plant species in the sand bars were Salsola komarovi, Carex pumila and Cynodon dactylon. In embryonic sand bars, Namusitdeung and Galmaegideung, the processes of vegetation development after colonization by pioneer species were closely interdependent with the development of the sand dune. The vegetation types of embryonic sand bars were divided into two groups: sand dune plants, and annual and perennial forbs. Those of old sand bars, Baeghapdeung and Ogryudeung, were also divided into tow groups: sand dune plants, and salt marsh plants. The results of interspecific association coincided well with the actual distribution of plant communities in the sand bars. The degree of vegetation development in each sand bar agreed with the order of successional stage observed in this study area.

In this study, a method to find the optimal intermediate die geometry for the multi-stage drawing process for the rectangular rod from a round bar is proposed and a program using the proposed method is developed. On the stage of the design of the intermediate die geometry, the virtual die was constructed using the initial billet as a inlet of the drawing die and the final product as a exit of that and the virtual die was divided by the number of pass. Divided die was transformed into the rectangular one which is the intermediate die geometry for the multi-stage rectangular drawing process. In order to verify the application of the proposed method on the real industrial product, the drawing of the rectangular rod from a round which composed two stage has been performed and simulated by the three dimensional rigid plastic finite element method.

Objectives: Chijasitang (CJST) has been prescribed for patients with anxiety disorder, and is believed to treat insomnia. The present study was carried out to investigate whether Fructus Gardeniae, Fermented Semen Sojae Preparatum and CJST have beneficial effects on treating anti-stress. Methods: The mice were divided into the following groups: normal, control, positive control, and experimental. Then, the experimental groups were further divided into the Fructus Gardeniae group (FG), the Fermented Semen Sojae Preparatum group (FS), the Chijasitang water extract group (CJSTW), and the Chijasitang 30% ethanol extract group (CJSTE). In the positive control group, a single dose of imipramine ($500{\mu}g/g$) was applied to the mice. In the experimental groups, each single dose of FG, FS, CJSTW and CJSTE ($50{\mu}g/g$) was applied to the mice. After one hour, the mice in all groups except the normal group were exposed to immobilization stress. Their body weights, phagocytosis, nitric oxide in macrophage, corticosterone, and adrenocorticotropic hormone (ACTH) were observed. Results: Fructus Gardeniae, Fermented Semen Sojae Preparatum and Chijasitang prevented weight loss and suppressed the decrease of phagocytosis in the mice after their exposure to immobilization-stress. Although they did not influence the amount of NO, they suppressed the increment of ACTH and corticosterone in the immobilization-stressed mice. Conclusions: According to the results of this study, they suggest that Fructus Gardeniae, Fermented Semen Sojae Preparatum and Chi-Ja-Si-Tang all have some anti-stress effects.

When thermal conductivity of rock is measured with PEDB (Portable Electronic Divided Bar) in a laboratory, it can be greatly influenced by the change of room temperature. Therefore, measuring the thermal conductivity in a thermo-hygrostat is necessary, where it can remain in its constant temperature and humidity condition. In this study, a system for thermal conductivity measurement in a thermo-hygrostat has been set up and the thermal conductivities for the 45 samples collected from GH3 and GH4 boreholes in Ulleung Island have been measured both in dry and saturated conditions. Also, the correlations between those thermal conductivities, density, and effective porosity have been discussed. As a result of correlation analysis among the thermal conductivity, density, and effective porosity, it showed higher correlation with dry samples than saturated samples. Especially, thermal conductivity ratio between saturated and dry conditions shows very high correlation ($R^2=0.90$) with effective porosity.

This study was undertaken to determine if Juglandis Semen Aquacupuncture(Ja) has a protective effect against glycerol-induced acute renal failure in rats. Rats were dehydrated for 24hr and then injected with $5m{\ell}/kg$ of 50% glycerol, one-half of dose in each hindlimb muscle. In experiments for Ja effect, rats received $0.1m{\ell}$ of Ja extraction in both sides of corresponding $Sh{\grave{e}}ns{\bar{u}}$($BL_{23}$) of human body and non-acupuncture points(the root of tail) for 3 days after injection of glycerol. The experimental group were divided into the Normal group, the Control group, the Ja to $Sh{\grave{e}}ns{\bar{u}}$($BL_{23}$) group(Ja-AS), the Ja to non-acupuncture points group(Ja-AN). There were significant decrease of Urine vollume, total protein and phosphate level in Ja-AS as compared with the control group. There were not any significant change of Urine creatinine in Ja-AS as compared with the control group. There were significant decrease of Unine glucose in Ja-AS, Ja-AN as compared with the control group. This suggests that Ja-AS could be used in prevention and treatment of acute renal failure. However, the precise mechanisms of Ja protection remain to be determined.

Objective : This study was undertaken to determine if Plantaginis Semen Aquacupuncture(PSA) has a protective effect against $CCl_4$ induced Hepatoxicity in Rats. Methods : The experimental group were divided into Normal group(untreated group), Control group, PSA group. Rats were administered orally $CCl_4$(0.1 ml/kg) for 4 days. In experiments for PSA effect, rats received 0.1 ml of PSA extraction in both sides of corresponding $G{\bar{a}}nsh{\bar{u}}$(BL18) of human body for 3 days after treated $CCl_4$. Variation of weight and biochemical assays(GOT, GPT, LDH, ALP, total cholesterol, triglyceride, albumin) were performed. Results : In Control group, $CCl_4$ increased serum GOT, GPT, LDH, ALP and albumin and decreased weight, total cholesterol and triglyceride. PSA significantly decreased serum GOT, GPT, LDH and increased total cholesterol as compared with Control group. Conclusion : These results indicate that PSA could be used in prevention and treatment of hepatoxicity. However, precise mechanisms of PSA protection remain to be determined.

Since at least the late 12th century, medical herbs grown naturally or cultivated in Korea have been referred to as 'HyangYak'(鄕藥, $Xi\bar{a}ngY\grave{a}o$). Herbs from other countries are referred to as 'DangYak'(唐藥, $D\bar{a}ngY\grave{a}o$). Some senior historians claim medicines made solely from HyangYak are purely Korean, since they originated and were developed fully within Korea. However, these localized medicines became abundant as the result of exchanges between Korea and other countries. Originally published in 1433, 'HyangYakJipSungBang' is the authoritative result of earlier writings of medical books using HyangYak. Comprised of a total of 85 volumes, it was large in scale and divided into three main sections: 1) a detailed description of the 703 kinds of HyangYak, 2) explanations of the 10,706 different herbal formulae and 959 types of symptoms or diseases, and 3) descriptions of the 1,416 various acupuncture and moxibustion formulae. It's noted that 'HyangYakJipSungBang' was not written all at once. In the process of its writing, the number of formulae increased through medical exchanges between Korea and China during the 15th century.

Tungsten heavy metal is characterized by a high density and novel combination of strength and ductility. Among them, 90W-7Ni-3Fe is used for applications, where the high specific weight of the material plays an important role. They are used as counterweights, rotating inertia members, as well as fur defense purposes(kinetic energy Penetrators, etc.). Because of these applications, it is essential to detemine the dynamic characteristics of tungsten alloy. In this paper, Explicit FEM(finite element method) is employed to investigate the dynamic characteristics of tungsten heavy metal under base of stress wave propagation theory for SHPB, and the model of specimen is divided into two parts to understand the phenomenon that stress wave penetrates through each tungsten base and matrix. This simulation results were compared to experimental one and through this program, the dynamic stress-strain curve of tungsten heavy metal can be obtained using quasi static stress-strain curve of pure tungsten and matrix.
