Purpose : Sasang Constitutional Medicine explains the pathology peculiar to constitution and suggests treatment for each constitution. In Sasang Constitutional Medicine hwnan beings are classified on four groups; Taeyangin, Taeumin, 5oyangin, Soeumin. These four constitution has their's own symptoms and treatments. In treatment, control of mind inclination, that is to say, moderation takes a very important role. But the study on heredity in Sasang Constitutional Medicine has not done not biological study but also statistical study. So we used several statistical methods and analyzed 163 samples. Methods : We implemented Fishers exact test for adjusting chi-squared test, kappa coefficient to estimate agreement of parent's and children's constitutions, and finally plotted bi-plot using correspondence analysis. Results : From Fisher's exact test result, we could know that parent's and children'S constitution's distribution had significant difference. In kappa coefficient, mother and daughter's estimated value produced highest result. In correspondence analysis we only plotted the case of mother and son for easy interpretation. Conclusion : In the study of heredity of SaSang constitution, we cannot know exactly the heredity of constitution in terms of biology or genetics. But this research can be helpful for further analysis, that is, a study of biological or genetical aspects. And we could conclude that in statistical aspects the heredity in SaSang constitution is meaningful.

The study was conducted to determine the effect of corssbred Korean native chickens (CKNC) on growth performance indices for hatch to 28 days. A total of 192 1-day-old birds were divided into one of 4 CKNC groups by 5 Korean native pure strains. Diets used in the study consisted of 2 phases with corn and soybean meal basis as earlier (1~2 weeks; crude protein 18.5%, metabolizable energy 3,000 kcal/kg), and grower (2~4 weeks; crude protein 15.0%, Metabolizable Energy 2,850 kcal/kg). Body weight and feed intake were measured bi-weekly. Crossbred 1G (group of family line) had higher body weight and average daily gain whereas crossbred 5Y had greater average daily feed intake and feed conversion ratio than other crossbred Korean native chicken for hatch to 28 days. The results in the current study indicated that crossbred 1G had higher growth performance indices compared with other crossbred Korean native chicken for hatch to 28 days.

A lot of foreign objects(ceramics, pottery, bronze, glassware and coins, etc.) have been found in the archaeological sites in Korea. These foreign objects are the evidences of the cultural exchanges of that time, whose scale and routes are an important part of the studies in ancient history. So it is crucial to accumulate basic reference information such as the raw materials and the production method of these objects through scientific researches, along with archeological researches. These scientific research materials provide a basis for finding the importing route and the origin of these objects. Besides, we can find out extraordinary and distinctive production technique by comparison with tile domestic objects. This article reports the result of an analysis, performing on 36 samples of the glassware fragments excavated from the South Tomb of the Hwangnamdaechong, to verify their components and note peculiar features. We have analyzed the major and minor components of 10 elements, and then by using these data examined the differences in the composition of components, varying with the origin and color of glassware. We used the PCA(principal component analysis) as the statistical method to classify the sample in order to find out how the samples formed groups.

Objectives: To determine the effectiveness of Tai-chi in treatinglow back pain. Methods: We searched 9 electronic databases(Pubmed, CAJ, EMBASE, Cochrane Library, Web of Science, KISS, KISTI, NDSL, and RISS) till April 2018 and included randomized controlled trials(RCTs) that used Tai-chi for lower back pain treatment. The methodological quality of each RCT was assessed usingthe Cochrane risk of bias tool. Results: As per the inclusion criteria, 5 RCTswere found to be eligible for our review. These studies were divided into 4 groups and meta-analysis was performed. The meta-analysis of 1 study showed favorable results regardingthe use of Tai-chi. Twostudies showed favorable results regardingthe use of Tai-chi with Tuina rather than Tuina alone. All studies were observed to have a high risk of bias. Conclusions: There is limited evidence available to support the effectiveness of Tai-chi in relieving low back pain;hence, additionalwell-designed RCTs should be encouraged for better evidence.

Background: The purpose of this study was to investigate differences in balancing ability and weight bearing between paretic and non-paretic. Methods: Subjects of the study were consisted of 30 acute hemiplegia patients(paretic 15, non-paretic 15) who were receiving rehabilitation therapy in hospital. Weight shifting was quantitatively evaluated to determine the ability of patients to and during conscious weight shifting on the Gaitview. Independent t-test was utilized to detect the mean difference between the groups. Results: 15 patients with stroke were able to shift more weight onto the paretic leg. And pressure ratio of right hemiplegia was significantly difference on the nonparetic leg, pressure ratio of left hemiplegia was significantly difference onto the paretic leg. Conclusions: Patients with left hemiplegia who was cortical lesions in the right hemisphere were able to shift more body weight onto their paretic leg. These patients should be encouraged to practice shifting their weight towards their non-paretic leg to improve their balance.

This study was conducted to investigate the effects of black raspberry wine which was administered per os on estrogen levels in Splague-Dawley(SD) rats. Black raspberry wine containing 13% alcohol(v/v) was prepared from ripe fruits of Rubus coreanus fermented with Saccharomyces cervisiae. The rats were divided into 2 groups(A and B): The group A received black raspberry wine and the group B received saline for 7 weeks. All animals were bi weekly monitored for estrogen levels by radioimmunoassay using $125^I$ labeled anti-estrogen monospecific antibody. There was a significant(2.02 fold) increase in estrogen levels in the group A with a peak at the 7th week post administration of black raspberry wine. There was no significant change in estrogen levels of the rats in the group B. These data point to uncharacterized phytoestrogenic bioactivity of black raspberry wine that appears to be a useful phytoestrogenic herbal remedy for human health.

The purpose of the present study was to evaluate the bioequivalence of two cimetidine tablets, Tagamet (Yuhan Pharm. Co., Ltd.) and Nex (Bi-nex Pharm. Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). The cimetidine release from the two cimetidine tablets in vitro was tested using KP Apparatus I method with various dissolution media (pH 1.2, 4.0, 6.8 buffer solutions and water). The dissolution profiles of two cimetidine tablets were very similar at all dissolution media. Twenty four healthy male volunteers were divided into two groups with a randomized $2{\times}2$ cross-over study. After four tablets (800 mg cimetidine) were orally administrated, blood was taken and the concentrations of cimetidine in serum were determined using HPLC with UV detector. The pharmacokinetic parameters such as $AUC_{t}$, $C_{max}$ and $T_{max}$ were determined. The result showed that the differences in $AUC_{t}$, and $C_{max}$ between two cimetidine tablets based on the Tagamet were -6.82% and -12.98%, respectively. There were no sequence effects between two tablets in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log(0.8) to log(1.25) (e.g., log(0.90)log(0.97) and log(0.82)log(0.93) for $AUC_{t}$ and $C_{max}$, respectively), indicating that Thrumetin tablet was bioequivalent to Tagamet tablet.

Finding poly(amidoxime) (PAO) based adsorbent with better performance in U(VI) extraction from seawater is a hot research topic. By employing plasma treatment, the bi-functionalized adsorbents containing amidoxime and phosphate (labelled as $PO_4/PAO$) were successfully synthesized. The obtained $PO_4/PAO$ was characterized and applied for the potential extraction of U(VI) from aqueous solution. The results show that $-PO_4$ enhanced the hydrophilicity of PAO. $PO_4/PAO$ possesses good selective sorption ability for U(VI) and excellent reusability. The findings is helpful to understand optimizing performance of PAO based adsorbents for uranium extraction from seawater.
