This study analyzed the expression of hanbok in online fashion styling games, and examined the main themes of and user reactions to hanbok fashion styling games through semantic network analysis and sentiment analysis. KrKwic, Textom, and NodeXL were used for data collection and analysis. The findings of the study are as follows: First, depending on the designer's expressive method, hanbok fashion styling games provide typical traditional hanbok, modern hanbok, and dress-like fusion hanbok, demonstrating contents with various themes for different sexes, classes, and situations. Second, as a result of analyzing the themes of hanbok-related styling game contents, it turned out that the main themes are tradition, color, historical drama, fusion hanbok, holiday, and love. Most of them produce modernized hanbok that reflect the situation and utility rather than strictly traditional ones. Third, as a result of analyzing user reviews of hanbok styling game contents, positive factors mostly turned out to be the satisfaction of the hanbok contents, with the users also showing positive intent to wear hanbok. Through this, it was found out that hanboks portrayed in game contents could potentially cause the user's positive intent to wear hanbok. Negative factors turned out to be the discordance between the intrinsic image of hanbok and the game character's image.

Recently, in many reptiles (14 genera of turtles in five families), common characteristics of incubation temperatures are known to determine the sexes of hatchlings in many species of turtles, including the map turtles, painted turtles and snapping turtles, emys turtle, etc. According to many researcher's reports, in general, incubation at $25^{\circ}C$ (cooler temperatures) produces all or mostly males, however, incubation at $31^{\circ}C$ (higher temperatures) or higher produces all or mostly females. Exceptionally, even cooler temperature ($20^{\circ}C$) produce females, they produced all or mostly females. Accordingly, it is well-known that incubation temperature is the sex determining agent in these turtles. However, this paper presents study of the sex ratio and nest ecology in natural spawning nest: Observations on hatching sex ratios of eggs collected from natural nests of T. sinensis are similar to a previous report of the same genus Trionyx in the soft-shelled turtles. However, this genus (or species) showed some different phenomena to other kinds of turtles such as various kinds turtles mentioned above. After collection of naturally spawned eggs (17 eggs of T. sisnensis) on the natural nests, a laboratory experiment by the constant incubation temperatures was conducted with natural fluctuating soil temperatures in the natural nest with the soft-shelled turtle, T. sinensis. And also laboratory experiments were conducted using constant incubation temperatures of $25^{\circ}C$ (cooler temp.) and $30^{\circ}C$ (higher temp.) with the turtle, T. sinensis. Exceptionally, it was confirmed that the first and second incubation temperatures can't control sex-determination in the freshwater soft-shelled turtle, T. sinensis. The sex ratio approximated 1:1 (${\chi}^2=0.06$, P>0.05 (the Ist experiment). And the sex ratio approximated 1:1 independently of incubation temperature (${\chi}^2=0.33$, P>0.05 (the 2nd experiment). Consequently, temperature has no effect on sex determination in the genus Trionyx in a soft-shelled turtle.

The elevation of plasma total homocysteine(tHcy) is now established as a risk factro for cardiovascular disease. It is also well known that plasma levels of folate and vitamin $B_{12}$ influences homocysteine metabolism as cofactors. Recently, the effects of health-related lifestyle factors, such as smoking, alcohol drinking coffee consumption, regular exercise, and etc, on plasma tHcy have been determined. The Hordalane Homocysteine Study revealed that smoking and coffee consumption are major deter minants of plasma tHcy as well as folate levels; however, the influence of alcohol intake is still controversial. In Koreans, the effects of lifestyle factors of plasma tHcy have not yet been determined. Thus, we investigated the relationships of various lifestyle determinants with plasma tHcy, folate, and vitamin $B_{12}$ levels and the erythrocyte folate concentrations in Korean adults (99 males and 96 fermales). Plasma tHcy levels were significantly hight in male subjects. On the contrary, plasma levels of folate and vitamin $B_{12}$ and erythrocyte folate concentration of the females were significantly higher than those of the males. Among the five lifestyle factors determined in the study, regular exercise significantly affects plasma tHcy levels only in the females, Contrary to the expectation, there were on significant differences in plasma tHcy levels between alcohol drinkers and non-alcohol drinkers as well as smokers and non-smokers. And also, plasma tHcy leverls were not different between coffee consumers and non-coffee consumer and between green tea consumers and non-green tea consumers. Although alcohol intake did not influence plasma tHcy levels, the duration, frequency, and amount of alcohol drinking showed significant negative relationships with plasma folate levers. These results indicate the regular exercise and alcohol intake might influence plasma levels of tHcy and folate in Koreans, although the results were not reveled in both sexes.

This study in concerned with the costume accessories appeared in Sam Kuk Sa ki. The accessories of both sexes were analized. Results of this research can be summarized as follows : It was appeared that names of accessories of men were fewer in number than those of women. Men\`s accessories such as a hat, bok-du, a belt,boots, shoes, and sock were mentioned in Sam Kuk Sa Ki. Women\`s accessories appeared such as a hat, a comb, a hair pin, a belt, shoes, and sock. A bok-du, boots, and a hared belt were used exclusively by men, while a hat, kwan(冠), a comb, a hair pin, a scarf, pyo( ) were worn exclusively by women. All men from different classes including true bone class as well as the common class wore bok-du, a hat, a hard belt, boots, sock ; however, class distinctions were made from materials used for those items. Also women\`s accessories were used as means of differentiating social status of the wearer by means of materials employed for each item. Especially, woman\`s hat and scarf were a symbol of the noble class. Only two classes of women from the true-bone class and women from the sixth du-pum class entited to wear hats. Wearing a scarf was not allowed to women from the common class. Class dirrernetiations were made by the materials used for hats and scarves. Materials for a scarf such as gold and silver leaf, pecock tail, and king fisher fly feather were restricted to women from true-bone class. Such as man\`s hat bok-du( 頭), use of women\`s comb and hair pin, scarf, leggings were items drived from Tang China. It clearly showed that costume accessories of Silla were heavily influenced by the Chinese. At the same time the costume accessories were sued to make sex difference among the people of Silla. Woman wore a soft belt made of cloth while man wore a hard belt. Woman\`s hat, a scarf, a comb, a hair pin, a belt or sash for a shirt, and leggings were woman\`s sex symbol. Thus, costume accessories of Silla appeared in Sam Kum Sa Ki functioned as means of differentiating social status of the wearer such as sex,class and rank in the society. Also, they showed that Silla kingdom had close cultural relationship with Tang China.

Biological mechanisms for ionizing radiation effects are different at low doses than at high doses. Radiation hormesis involves low-dose-induced protection and high-dose-induced harm. The protective component is associated with a reduction in the incidence of cancer below the spontaneous frequency, brought about by activation of defensive and repair processes. The Linear No-Threshold (LNT) hypothesis advocated by the International Commission on Radiological Protection (ICRP) and the Biological Effects of ionizing Radiation (BEIR) Report VII for cancer risk estimations Ignores hormesis and the presence of a threshold. Cancer incidences significantly less than expected have been found in a large number of epidemiological studies including, airline flight personnel, inhabitants of high radiation backgrounds, shipyard workers, nuclear site workers in scores of locations throughout the world, nuclear power utility workers, plutonium workers, military nuclear test site Participants, Japanese A-bomb survivors, residents contaminated by major nuclear accidents, residents of Taiwan living in $^{60}Co$ contaminated buildings, fluoroscopy and mammography patients, radium dial painters, and those exposed to indoor radon. Significantly increased cancer was not found at doses <200 $mSv^*$. Evidence for radiation hormesis was seen in both sexes for acute or chronic exposures, low or high LET radiations, external whole- or partial body exposures, and for internal radionuclides. The ubiquitous nature of the Healthy Worker Effect (HWE)-like responses in cellular, animal and epidemiological studies negates the HWE as an explanation for radiation hormesis. The LNT hypothesis is wrong and does not represent the true nature of the dose-response relationship, since low doses or dose-rates commonly result in thresholds and reduce cancer incidences below the spontaneous rate. Radiation protection organizations should seriously consider the cost and health implications of radiation hormesis.

This study was performed to clarify the induction possibility of anaphylactoid reactions by the administration with the heartworm extracts, and, if any, to elucidate different virulences in terms of the protein concentrdtions and sexes of Dirofilaria immitis. Twenty three clinically healthy D. immitis-free adult dogs were used in the present study. The experimental animals were divided into 5 groups. Group A (5 heads) was administered with an female heartworm extract containing 0.1 g/dl protein concentration. Group B (4 heads) was administered with an male heartworm extract containing 0.1g/dl protein concentration. Group C (5 heads) was administered with an female heartworm extract containing 0.2 g/dl protein concentration. Group D (4 heads) was administered with an male heartworm extract containing 0.2 g/dl protein concentration. Group E (5 heads) was administered with an female heartworm extract containing 0.4 g/dl protein concentration. The changes of clinical symptoms and vital signs (body temperature, heart rate and respiration rate) were examined before and 5 minutes, 15 minutes, 30 minutes, 1 hour, 2 hours and 24 hours after injection with the extracts, respectively. In addition, the changes of hematological values (RBC, PCV and total leukocytes counts), serum chemical values (ALP and CK) were determined. It was considered that heartworm extract could induce anaphylactoid reaction and adult female heartworm extract was more affective than those of adult male heartworm extract in the changes of clinical symptoms, vital signs, hematological values and serum chemical values.

The objectives of this study are to estimate the prevalence of diabetes mellitus (DM) and to identify risk factors associated with fasting blood sugar in a rural adult population. We carried out a cross - sectional study on the residents over 30-year old. Among the 1077 eligible subjects, 725 persons responded to the study;the study consisted of interview on family and past history of DM, anthropometry, blood pressure, and blood sugar level in each subjects. Only 707 subjects of 725 participants had fasting blood sugar(FBS) examined and the rest, 18 subjects were had casual blood sugar examined due to failure of fasting over 8 - hour. When subjects had $FBS\geq140mg/dl$, 2 hours postprandial blood sugar level was checked after 75g oral glucose loading. The prevalence of DM was 8.9%, and age standarized prevalence rate adjusted to Korean population of 1995 was 5.8%. Mean and SD of fasting blood sugar in men was $99.8{\pm}22.6$, and in women was $111.5{\pm}29.9$. Mean levels of fasting blood sugar were significantly higher in women than in man and as their ages advanced the prevalences increased in both sexes. PP2 blood sugar levels were significantly higher in elder age and in persons with higher FBS levels than others. The risk factors associated with FBS were past history of diabetes, sex, socioeconomic status and waist - to - hip circumference ratio;the risk of diabetes was increased in female, people with past DM history, central obesity and low socioeconomic state. The low socioeconomic status associated with DM in this study, which is different from other study results, should be pursued in further studies.

Background: Although a variety of instruments implement body maps for the precise identification of pain symptoms, no instrument has been validated for use in people with obesity. This study reports the adaptation and validation of body maps for musculoskeletal pain location in people with obesity. Methods: Nine key anatomical regions were highlighted based on the original images of the Nordic Musculoskeletal Questionnaire body maps. Adult silhouettes were generated from photographs of men and women with obesity. The body dimensions were adjusted to take into account the different body fat distribution patterns of people with obesity. The validity of the images was assessed by 12 experts. Subsequently, a data collection stage was performed with 58 patients with severe obesity from both sexes. The reproducibility of the images was tested by comparison with the original images. Results: The results of the validation pilot study indicated that the adapted images facilitated the location of musculoskeletal pain in men and women with obesity. The reproducibility of the original and adapted versions of the body maps indicated good agreement for pain over the last 12 months and 7 days (80% vs. 79.7%). Pain scores in the last 12 months indicated good and high sensitivity and specificity for all body areas (60.9% vs. 89.1%). Considering pain in the last 7 days, high sensitivity and specificity for all areas of the body (85.1% vs. 70.1%). Conclusions: The body maps developed in this study are reliable and valid to identify the location of pain in people with obesity.
