This study was performed to observe the effect of hyulbuchukeo-tang and its component groups on recovery of hepatoxicity in alloxan treated rats. The experimental group was divided into 3 groups: hyulbuchukeo-tang(HCT) and its components groups, sayeok-san(H-sa) and dohong-samul-tang (H-do). The results were obtained as follows: 1. The level of Glucose was considerably reduced by HCT, H-sa, H-do with high significancy. 2. In the change of GOT activity, HCT and H-do were decreased with high significancy, H-do was decreased with some significancy. 3. In the change of GPT activity, HCT was decreased with high significancy, H-sa and H-do were decreased with some significancy. 4. In the change of ${\gamma}-GPT$ activity, HCT was decreased with high significancy, H-do was decreased with some significancy. 5. In the change of ALP activity. only HCT was decreased with some significancy. 6. In the change of LDH activity, HCT was decreased with high significancy, H-sa and H-do were decreased with some significancy. 7. In the change of bilirubin contents. only HCT was decreased with some significancy. As result, hyulbuchukeo-tang(HCT) has significant effects on recovery of hepatoxicity, and its components groups. sayeok-san(H-sa) and dohong-samul-tang(H-do) have some effects. It suggests that sayeok-san(H-sa) and dohong-samul-tang(H-do) have more effects on recovery of hepatoxicity in case of the combination of the two (that is hyulbuchukeo-tang) than in case of the separation.

Since recent development of questionnaire for Sasang constitution, many researches have followed it to verify statistical significancy. However, a few problems about validity of some questionnaires were discovered later on due to the lack of researches about it. Firstly, some questionnaires have different meaning from that of the original Dongyi Suse Bowon. Secondly, belief on statistical significancy sometimes misleads the questions for a certain Sasang constitution to be used for a different Sasang constitution. Thirdly, profound concepts of original Dongyi Suse Bowon are sometimes abandoned or ignored in the excuse of low statistical significancy. Fourthly, it is still difficult to identify Sasang constitution of Taeyangin due to lack of population, sample, and questions. The purpose of this thesis is to minimize the problems related with interpretation and fitness of the questionnaires. The author developed a questionnaire of 48 questions and surveyed with it over 200 patients who visited Jeon-ju Woosuk hospital. This research resulted in a bit of resolution of the problems through statistical comparison between the survey and clinical analysis.

The aim of this study was to evaluate the efficacy of a topical 0.2% hyaluronic acid (HA) preparation in the management of wound after removal of arch bar for facial bone fracture and a suture site after orthognatic, oral cancer or oral surgery. Forty patients participated in a randomized, placebo controlled, double-blind trial to evaluate the efficacy of the topical HA and preparation. HA topically applied to the wound after removal of arch bar or stitch out, 3 times a day for 4 weeks. Evaluation is performed once a week for 4 weeks. For subjective evaluation, relative pain reduction in visual analog scale (VAS) and existence of heat sensation was accessed. For objective evaluation, gross evaluation, papilla index, existence of wound dehiscence, redness and swelling was checked. The same evaluation was performed in each arch bar group and suture group. For whole subject, 0.2% HA group resulted higher reduction than placebo group in pain of site in first week with significancy. Same findings were seen other weeks but there was no significancy. 0.2% HA group had better result than placebo in objective evaluation (papilla index, wound dehiscence, redness and swelling), but in gross evaluation placebo had better result than 0.2% HA group with no significancy. Subject was divided into suture group and arch bar group. Same aspect was seen, but only suture group had significancy not arch bar group in pain reduction score. 0.2% HA group resulted higher reduction than placebo group in pain of site in first week with significancy, especially in suture group. It reveals topical application of HA in wound especially suture site reduced pain in early stage. And 0.2% HA group had better result than placebo in papilla index, redness and swelling with no statistical significancy. In conclusion, HA has effect of pain reduction and healing promotion in the mucosal wound after oral surgery.

The purpose of this study was to reseach the effect of Daesihotang and its component groups on diabetes, free radical and antioxidative defense system in alloxan-induced diabetic rats. The experimental group was divided into three groups: Daesihotang (DS), Soyangyak (DS1), Yangmyungyak (DS2). The results were obtained as follows: The level of glucose, triglyceride, total cholesterol, creatinine in serum were considerablely reduced by Daesihotang. And the level of HDL cholesterol, albumin, total protein in serum were increased by Daesihotang significantly. And the level of BUN has some decreased, but with no significancy. In the study of Daesihotang on free radical scavenging effect in vitro, it has shown that Daesihotang and its components group have significant suppressing effect on peroxidation of linoleic acid on concentration. And in other experiments as scavenging effect of DPPH radical, inhibitory effect of superoxide in xanthine-xanthine oxidase system and inhibitory effect on lipid peroxidation reaction by hydroxy radical in $H_2O_2-Fe^{2+}$ system, Daesihatang have some activity, but with no significancy. In the study of Daesihotang on antioxidative defense system in vivo, the activity of GOT and GPT in serum were significantly increased; and the amounts of lipid peroxide in serum was reduced significantly but in liver no significancy. In hepatic catalase activity, Daesihotang has showed significant effect. In the level of hepatic glutathione, Daesihotang increased the amount of glutathione significantly. And in the activity of glutathione-s-transferase, Daesihotang has decreasing effect but has no significancy. These result suggest that Daesihotang has strong effect on diabetes and it is useful to prevent diabetes, but has less effect on peroxidative damage by free radical.

The color changing of the wood surface was tested by accelerated weathering test that can simulate the outdoor condition with short period. In early parts of accelerated weathering test, weight and volume of specimen all were increased due to the moisture evaporation by its high temperature and illumination level, but weight and volume of specimen all were decreased from middle parts to last. However, significancy showed between control group and accelerated weathering test group in terms of weight and volume. According to the results of color-difference meter, in the early parts of the accelerated weathering test lightness, redness and yellowness all showed a clear increasing or decreasing trend. However, after three weeks all values were almost never change. Until the early parts of the test, lightness was decreased and there was not a considerable change after three weeks in the test. Redness showed a some change in early parts of the test, but this also showed not great change after middle parts of the test as like lightness. Yellowness also showed same pattern. These results could be verified through the visual inspection. As like weight and volume, significancy showed between control group and accelerated weathering test group in terms of color-difference test. In all accelerated weathering test group, color-differences of after test was lower than that of before test. To correctly analyze this cause, more additional research will be need on each of temperature, humidity and illumination factors.

Recently, the demand and supply on the Hanok have been increased. However, Hanok should be requested larger section of structural members because of excessive roof weight. So, structural skin-timber was manufactured to get a lightweight structural member. The structural skin-timber has exterior shape with larger section but a great volume of wood be removed. The reduced strength of structural skin-timber can be supplemented by hybridizaion of structural member. Japanese larch and Domestic pine were used to manufacture the structural skin-timber. Structural skin-timbers of rectangular shape and cylinder shape were manufactured and tested to evaluate the bending properties. The intended strength property could not be obtained because member had been suffered severe damage by precision deficiency of manufacturing machine. However, if precision of manufacturing machine would be improved and additional hybridizaion of structural skin-timber would be done, lightweight structural member will be able to be manufactured. Structural skin-timber did not showed statistical significancy between two species, so it is possible to use pine mixed with larch. Only MOR of larch showed statistical significancy between rectangular shape and cylinder shape, so it is necessary to use of those as separate things. However, the rest of skin-timber can be judged mixed using because of non statistical significancy. The objective of this study was the development of lightweight larger structural member with relatively strength. If hybrid member of skin-timber could be developed with wood-ceramics, lightweight steel and more, it can be possible to be used as a building material of Hanok, interior material, post & beam construction material and more.

The purpose of this study was to assess the soft tissue changes of upper lip & nose using 38 patients who treated with Le Fort I osteotomy for the correction of dentofacial deformities. Patients were devided into three groups. One was advancement group of maxilla(Group I, N=14), another was impaction group of maxilla(Group II, N=12) and the other was combination group(advancement & impaction)(Group III, N=12). Preop. and 1 month postop. (T1), preop. and 6 months postop.(T2) were analyzed and compared. The results obtained were as follows : 1. The upper lip thickness(UL-VP) moved anteriorly approximately 62% of the horizontal maxillary change and this was significant in the advancement group(Group I) 2. The upper lip length(Stm-Sn) and the lower border of upper lip(Stm) moved superiorly 25%, 40% of the maxillary impaction group(Group II) (P<0.05) 3. There was significancy in the upper lip thicness(UL-VP) approximately 56% of the combination group(Group III) (P<0.05) 4. The nasolabial angle decreased in all groups, but there were no significancy.
