Objectives Syndrome differentiation and treatment (辨證論治) is one of the core theories in Korean medicine and syndrome differentiation (辨證) constitutes a branch of disease diagnosis in Korean medicine. Yoon Gil-Young, one of the modern outstanding scholar of basic medical science in Korean medicine, wrote on basic theories of Korean medicine such as physiology, pathology, formula science, etc. Hereby we will analyze and discuss his works to understand his recognition of historical changes in the syndrome differentiation. Methods We conducted researches into the two works of Yoon Gil-Young's, which are "The Clinical Formula Science of Eastern Medicine (東醫臨床方劑學)" and "The theory of Four-Constitution Medicine (四象體質醫學論)". From Yoon's academic standpoint which connects the basic medical science with the clinical medicine, we analyzed his opinion about syndrome differentiation and its historical changes. Results According to Yoon's research work on syndrome differentiation and its historical changes, the development of syndrome differentiation, which goes in harmony with the history of Korean medicine, has its deep root in " Huangdi's Internal Classic (黃帝內經)" and "Treatise on Cold Damage and Miscellaneous Diseases (傷寒雜病論)". And through "Treatise on the Spleen and Stomach (脾胃論)" and the articles of warm disease (溫病論), the theory of syndrome differentiation became extended to the whole clinical diagnostic field in Korean medicine, finally including the achievements in "Treasured Mirror of Eastern Medicine (東醫寶鑑)", "Longevity and Life Preservation in Eastern Medicine (東醫壽世保元)". Conclusions Yoon Gil-Young recognized that the system of syndrome differentiation was developed in accordance with the theories from the "Treatise on Cold Damage and Miscellaneous Diseases", then the "Treatise on the Spleen and Stomach" and the articles of warm disease. The four-constitution medicine in Korea and Koho school in Japan which lays emphasis on abdominal signs also contributed to its development. Syndrome differentiation can be categorized basically into three states of intrinsic cold (本寒), intrinsic deficiency (本虛), intrinsic heat (本熱) according to the deficiency and excess in human body metabolism.

Backgroud: Excess abdominal fat, expressed as an increased ratio of waist to hip circumferences (WHR), is independently associated with higher levels of blood pressure. Although a WHR greater than 1.0 in men has been shown to predict complications from obesity, the WHR has not been evaluated in all ethnic groups. Methods: In order to ascertain the association between WHR and classification of blood pressure and to investigate the critical value of WHR as a predictive factor of hypertension in Korean middle-aged men, we compared the mean of WHRs according to the classification of blood pressure in Seoul Cohort participants. Results: Through a surrey of direct measurement of waist and hip girth, 452 subjects were recruited from the cohort. The mean of WHR was 0.88 and its standard deviation was 0.04. The mean of WHRs was higher in the systolic blood pressure group (above 140 mmHg), diastolic blood pressure group (above 90 mmHg), and hypertension group than in the systolic blood pressure group (below 140 mmHg), diastolic blood pressure group (below 90 mmHg), and normotensive group, respectively. And WHR of above 0.89 was associated with hypertension (z-value =6.66). Conclusion: It is necessary for Korean males with WHR greater than 0.89 to recommend the primary prevention and early defection of hypertension.

This study investigated the pollution status of polycyclic aromatic hydrocarbons (PAHs) such as benzopyran, which is a harmful substance, in convergence herbal pills distributed in Seoul. During 2010 ~ 2013, 31 items and 93 samples were collected from the herbal medicines vendors in Seoul, and the samples were extracted, filtered, concentrated, and then spun out with SPE (Sep-pak florisil) and concentrated again and analyzed by liquid chromatography. The results of the analysis showed that the average contents of PAHs were below $10{\mu}g/kg$, and the PAHs were lower than those of daily life exposure, and MOEs was evaluated as safe to a negligible level. In the future, comparative fusion studies on the harmful substances of medicinal pills and food pills are needed.

Purpose: X-ray exposure should be clinically justified and each exposure should be expected to give patients benefits. Since dental radiographic examination is one of the most frequent radiological procedures, radiation hazard becomes an important public health concern. The purpose of this study was to investigate the attitude of Korean dentists about radiation safety and use of criteria for selecting the frequency and type of radiographic examinations. Materials and Methods: The study included 267 Korean dentists. Five questions related to radiation safety were asked of each of them. These questions were about factors associated with radiation protection of patients and operators including the use of radiographic selection criteria for intraoral radiographic procedures. Results: The frequency of prescription of routine radiographic examination (an example is a panoramic radiograph for screening process for occult disease) was 34.1%, while that of selective radiography was 64.0%. Dentists' discussion of radiation risk and benefit with patients was infrequent. More than half of the operators held the image receptor by themselves during intraoral radiographic examinations. Lead apron/thyroid collars for patient protection were used by fewer than 22% of dental offices. Rectangular collimation was utilized by fewer than 15% of dental offices. Conclusion: The majority of Korean dentists in the study did not practice radiation protection procedures which would be required to minimize exposure to unnecessary radiation for patients and dental professionals. Mandatory continuing professional education in radiation safety and development of Korean radiographic selection criteria is recommended.

We processed meta-analysis to test if the effects of laser therapy and mobilization techniques are evidence-based practice for treating tennis elbow. By researching and collecting the results of previous studies on tennis elbow, we inquired into the difference in the effects of each treatment methods on pain, grip strength, and ROM. A total of 10 international and domestic articles on the treatments of tennis elbow were selected for this study, including 7 articles on the effect of laser therapy and 3 on mobilization techniques. According to the qualitative meta-analysis, all 7 of the articles on laser therapy and 1 of the mobilization technique were double-blinded and randomized the subjects, and all of the 10 studies were designed in a high quality research, using statistics. The results of the studies on laser therapy showed in terms of statistical significance: 4 out of 7 did not decrease pain after therapy, and 3 out of 5 did not increase grip strength after therapy. In the studies on the effects of mobilization technique, both the 2 studies significantly increased grip strength after therapy. For other studies which measured ROM and tension, the mobilization therapy increased ROM significantly, and decreased tension significantly. The results of our study are shown in a diverse form in terms of the effects of different therapy techniques. This is related to the accuracy of the measurement tools for assessments and diagnoses. Further qualitative studies on the evidence-based practice and researches on tennis elbow are needed.

The purposes of this study were to investigate the names and locations of beauty-related high schools, and to examine the cources and subjects of beauty-related high schools according to types of high schools. Data were obtained from 8 beauty-related high schools, which consisted of 2 schools for each beauty-related high schools types and permitted the investigation of their curriculum. The findings of this study were as follows: First, These were about 30 beauty-related high schools that were mostly industrial high schools, located in Busan and Kyungsang Province, and almost used "Beauty" or "Aesthetics" as the name of department. Second, the rates of common and professional courses of business high schools and industrial high schools were similar to those suggested from the Ministry of Education and Human Resources. But for specialized high schools and integrated high schools, the rate of these courses were not in accord with those of the Ministry of Education and Human Resources. Third, The credit hour of special study in beauty-related high schools largest in hair care, followed by skin care and makeup courses. But nail and foot care were established only 2-3 beauty-related high schools. Fourth, The number of subjects of special study were largest in specialty high school. Industrial high schools offered the least number of subjects of special study. Fifth, as a result of making a comparative analysis of their subjects of special study, eight high schools offered hair care, skin care, public health and makeup courses, which had the same or similar titles. The independence titles were established nail care and foot care. The others titles were established actual training, food and nutrition, digital image processing, accounts theory, coordinatin.

The community size of culturable heterotrophic bacteria and community level physiological profiles (CLPP) in the rhizosphere of Brassica rapa subsp. pekinensis (Chinese cabbage) were analyzed in two different sites. The average community size of culturable heterotrophic bacteria ranged between $2.65\times10^6CFU\;g^{-1}$ soil (Suwon) and $3.75\times10^6CFU\;g^{-1}$ soil (Yesan), whereas those of bulk soils ranged between $2.45\times10^6CFU\;g^{-1}$ soil (Suwon) and $2.97\times10^6CFU\;g^{-1}$ soil (Yesan). The average functional richness of Suwon rhizoshpere was 90.8, whereas that of Yesan rhizosphere was 154.1. High level of correlation was found between the community size and functional richness. The most actively utilized substrates in both rhizospheres were adonitol, L-asparagine, D-gluconic acid, L-glutamic acid and D-galacturonic acid. Clear differences were seen in the utilization patterns between the two sites. Differences were also observed for the patterns of bulk soils between the two sites, although D-raffinose and D-mannose were found as the commonly utilized substrates.

Nitrate contamination in water system is a critical environmental problem caused by excessive application of chemical fertilizer and concentration of livestock. In order to prevent further contamination, therefore, it is necessary to understand the origin of nitrate in nitrogen loading sources and manage the very source of contamination. The objective of this study was to examine the nitrate contamination sources in different agricultural system by using nitrogen isotope ratios. Groundwater and runoff water samples were collected on a monthly basis from February 2003 to November 2003 and analyzed for nitrogen isotopes. The nitrate concentrations of groundwater in livestock fanning area were higher than those in conventional and organic fanning area and exceeded the national drinking water standard of 10mg N/ l. The ${\delta}^{15}N$ranges of chemical fertilizer and animal manure were - 3.7${\sim}$+2.3$\textperthousand$ and +12.5${\sim}$26.7$\textperthousand$, respectively. The higher ${\delta}^{15}N$ of animal manure than those of chemical fertilizer reflected isotope fractionation and volatilization of '''N. The different agricultural systems and corresponding average nitrate concentrations and ${\delta}^{15}N$ values were: conventional farming, 5.47mg/e, 8.3$\textperthousand$; organic fanning, 5.88mg/e, 10.1$\textperthousand$; crop-livestock farming, 12.5mg/e, 17.7%0. These data indicated that whether conventional or organic agriculture effected groundwater and runoff water quality. In conclusions, relationship between nitrate concentrations and ${\delta}^{15}N$ value could be used to make a distinction between nitrate derived from chemical fertilizer and from animal manure. Additional investigation is required to monitor long-term impact on water quality in accordance with agricultural systems.

Objectives: Little is yet known about the determinants of bone mineral density (BMD) in young adults. Thus, in this study, we aimed to determine the factors that have an impact on BMD in young men. Methods: Questionnaires were sent out to 111 male medical students. Information on age, socio-economic status, medical history, lifestyle, physical activity during adolescence, school club participation, current physical activity, and dietary intake were collected by the survey. Height, weight, percent body fat and muscle mass were estimated by bioelectrical impedance, and BMD was obtained using calcaneal quantitative ultrasound. Using the Poisson regression model, prevalence ratios (PRs) were used to estimate the degree of association between risk factors and osteopenia. Results: The height and current physical activity showed a correlation to the Osteoporosis Index. Among the categorized variables, past physical activity during adolescence (p= 0.002) showed a positive effect on the bone mineral content. In the multivariate model, past physical activity (${\geq}1$ time/wk) had a protective effect on osteopenia (PR, 0.37; 95% confidence interval [CI], 0.18 to 0.75) and present physical activity (1000 metabolic equivalent of task-min/wk) decreased the risk of osteopenia (PR, 0.64; 95% CI, 0.44 to 0.91). Conclusions: Past physical activity during adolescence is as important as physical activity in the present for BMD in young men.

This study was carried out to investigate the antimicrobial and anticancer effects of Galla Rhois (GR) on pathogens isolated from oral and KB human oral epidermoid carcinoma cells. Their antimicrobial activities were tested against Streptococcus mutans (S. mutans), Staphylococcus aureus (S. aureus), Enterobacter aerogenes (E. aerogenes), Escherichia coli (E. coil) and Candida albicans (C. albicans). GR powder has the antimicrobial activity against C. albicans, S. mutans and S. aureus. The extracts of water and ethanol have the antimicrobial activity against S. sureus and C. albicans. The water extract showed inhibitory activity against the growth and pH of above mentioned reference microorganisms. The water extract of GR declined cell viability in a dose dependent manner. DNA flow cytometric analysis showed that population of sub-G/sub 0//G₁, phase of cell cycle was increased by GR extract treatment in a dose dependent manner. Western blot analysis revealed that Caspase-3 was reduced by GR extract treatment. These result suggested that GR has the effect of antimicrobial on pathogens isolated from oral, and also, has anticancer effect that associated with the induction of apoptosis in a dose dependent manner in KB human oral epidermoid carcinoma cells. It may be GR-induced apoptosis was mediated via activation of Caspase-3.
