Purpose: To assess the possibility of using panoramic indices as an indicator of jaw osteoporosis. Methods: Mandibular cortical width (MCW), degree of mandibular alveolar bone resorption (ABR) and morphology of mandibular inferior cortex (MIC) on panoramic radiograph were used as panoramic indices. These panoramic indices were compared with bone mineral density (BMD) of lumbar (L1-L4) and femoral neck measured by dual energy X-ray absorptiometry. We also compared MCW and ABR of young men with those of postmenopausal women. Results : There was a significant correlation between ABR and BMD of lumbar and femoral neck. And also significant correlation between MIC and BMD of lumbar and femoral neck. ANOVA test of BMD of lumbar and femoral neck showed significant differences according to morphologic classification of inferior cortex. There was significant difference in MCW and ABR between young men and postmenopausal women. Conclusion: Our results suggested that ABR and MIC on panoramic radiograph could be reliable in screening of osteoporosis.

Monomelic amyotrophy (MA), also known as Hirayama disease, occurs mainly in young men and manifests as weakness and wasting of the muscles of the distal upper limbs. Here, we sought to identify a genetic basis for MA. Given the predominance of MA in males, we focused on candidate neurological disease genes located on the X chromosome, selecting two X-linked candidate genes, androgen receptor (AR ) and ubiquitin-like modifier activating enzyme 1 (UBA1). Screening for genetic variants using patients' genomic DNA revealed three known genetic variants in the coding region of the AR gene: one nonsynonymous single-nucleotide polymorphism (SNP; rs78686797) encoding Leu57Gln, and two variants of polymorphic trinucleotide repeat segments that encode polyglutamine (CAG repeat; rs5902610) and polyglycine (GGC repeat; rs3138869) tracts. Notably, the Leu57Gln polymorphism was found in two patients with MA from 24 MA patients, whereas no variants were found in 142 healthy male controls. However, the numbers of CAG and GGC repeats in the AR gene were within the normal range. These data suggest that the Leu57Gln polymorphism encoded by the X-linked AR gene may contribute to the development of MA.

Objectives: Osteoporosis is the most common metabolic disease of the bone, and is one of the most important major public health problems world wide. It is more occurred in female than male, but as the osteoporosis of men is increasing, therefore bone fractures of men are increasing. So we investigated the factors which are related to Bone Mineral Density(BMD) of male for prevention of osteoporosis. Methods: We measured the Bone Mineral Density(BMD) of lumbar spine($L_2$-$L_4$) and femoral neck in 5198 male, using dual energy X-ray absorptionmetry(DEXA; DPX-alpha). And then we analysed the 8 factors - age group, bone mass index(BMI), amount of smoking, drinking, exercise, and fast blood sugar, gastric disease, thyroid disease - which are related to BMD of male. Results: 1. In age group according to ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$, T-score was the highest at 17-24(三八歲) years group and decreased rapidly after 57-64(八八歲) years group in both lumbar spine($L_2$-$L_4$) and femoral neck. Therefore we concluded that T-score of male in lumbar spine($L_2$-$L_4$) and femoral neck change according to age group in ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$. 2. In BMI(body mass index), T-score of lumbar spine($L_2$-$L_4$) and femoral neck were the highest in obese group than non-obese group. In comparison of age group according to BMI, T-score of lumbar spine($L_2$-$L_4$) was significant difference in 17-72 years group and T-score of femoral neck was in 25-72 years group. 3. In exercise, T-score of lumbar spine($L_2$-$L_4$) and femoral neck was increasing as exercising more. In comparison of age group according to exercise, Both T -score of lumbar spine and femoral neck were significant difference in 25-72 years old. 4. T-score of lumbar spine($L_2$-$L_4$) was the highest in men who have taken exercise daily, and T-score of femoral neck was the highest in men who have taken exercise 1-3 times for a week. Conclusions : The age group in ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$ is related to BMD of men. And risk factors - BMI, exercise - are related to BMD of men. Therefore we expect that this study will help for prevention of osteoporosis of men.

The purpose of this study is to examine the characteristics of men's wear designs unveiled while Hedi Slimane worked for Dior Homme and Yves Saint Laurent. The study will analyze and focusing on the modernistic characteristics in order to discover the postmodernism trends in his works. The results of the research are as follows. First, Hedi Slimane's fashion style can be cited as grunge and punk due to the trend of expressing the subculture of postmodernism. The design features shown in Dior Homme were straight lines, leather, metallic materials and dark colors used to reinterpret a grungy punk style, romantic patterns, glossy materials, elastic leather, and bright colors were the salient features of Yves Saint Laurent. Second, the feature of cultural pluralism of postmodernism appeared as a type ethnic style. He presented this through the Third World images in the Dior Homme but Spanish matador images, Marrakech's images and North African images in the Yves Saint Laurent. Third, he feature of his style is metrosexual feminizing men's fashion and breaking up gender stereotypes. I-type and X-type silhouettes that emphasize the human body and feminine design motifs such as a skirt are dominated in Dior Homme, and he completed the metrosexual style by using materials, colors and patterns such as bright feminine pink, red, laces, fur, floral and leopard prints, as well as flagrantly expressing body contour.

Background: The aim of this study was to examine the correlation between the number of remaining natural teeth (NRT) and the appendicular skeletal muscle mass index (SMI) in older adults. Methods: This study was based on data from the 2008-2010 Korea National Health and Nutritional Examination Surveys. The participants were 2,378 older participants (984 men and 1,394 women) aged over 65 years. Survey dentists conducted oral health examinations, and ASM was measured using dual-energy X-ray absorptiometry. Results: The participants with $NRT{\geq}20$ had more ASM and SMI than those with NRT<20 in both sexes. SMI was correlated with NRT in men (r=0.018, p<0.001) and in women (r=-0.007, p<0.001). The positive correlation between the NRT and SMI remained significant in men even after adjusting for age, marital status, income, smoking, drinking, physical activity, protein intake, energy intake, calcium intake, body mass index, fasting blood glucose level, medications, and prostheses (${\beta}=0.011$, p=0.001). In women, the correlation disappeared after adjustment for smoking, alcohol, physical activity, protein intake, energy intake, calcium intake, marital status, income, fasting basal glucose, medication administration, and prostheses. Conclusion: This study showed a correlation between NRT and SMI in those ${\geq}65$ years of age in Korea. The relationship persisted in men, but not in women, even after adjusting for confounders.

Objectives: To objectively determine and compare the physical activity (PA) levels of adults newly diagnosed with type 2 diabetes (T2D) and adults without T2D in Vietnam using an accelerometer. Methods: A total of 120 participants with newly diagnosed T2D and 120 adults without T2D were recruited from a large hospital in Hanoi, the capital city of Vietnam. All participants wore an ActiGraph GT3X accelerometer for at least 5 days, including 1 weekend day. Freedson cut-off points were used to estimate different intensities of PA. In addition, comparisons between groups were made with respect to achieving the World Health Organization (WHO) and International Diabetes Federation (IDF) recommended PA guidelines. Results: Men with T2D had significantly lower levels of PA than men without T2D. The respective multivariable-adjusted mean values of daily step count, daily light-intensity, moderate-intensity, and moderate-to-vigorous-intensity PA were approximately 14%, 19%, and 22% lower in the men with T2D than in their non-T2D counterparts. However, women with T2D accumulated a greater number of steps per day than women without T2D. Only 59.2% of the adults with T2D met the minimum recommended level of PA (WHO and IDF), compared to 74.2% of adults without T2D (p<0.05). After adjusting for potential confounders, participants with T2D experienced 50.0% significantly lower odds of achieving PA recommendations. Conclusions: Vietnamese men with T2D were less physically active than those without T2D, and adults with T2D were less likely to meet PA guidelines. The results suggest a need for integrating PA into the self-management of this chronic condition.

The purpose of this study was to understand clothing condition of elderly men focusing on somatotype variation and satisfaction with ready-to-wear and to provide basic data in designing ready-to-wrar for the elderly men. The questionnaire method was used and one-to-one interviews were held for the elderly residents in Seoul, Deajon, Jonju, and Yeosu areas. The total of 275 questionnaires (from 148 elderly men in the 60's, 99 in the 70's and 28 in the 80's) were collected and used for statistics. SAS package was used for the statistics and the statistics were based on frequency, X2-test, ANOVA, Duncan's multifle range test. The results of the study were as follows; 1) Height (p< .05), weight (p< .001) and Rohrer index (p< .05) decreased significantly with ageing 2) The somatotypes of 75.6% were changed and the 70's 8t the 80's showed significantly (p< .05) higher changing rate compared to the 60's and more changes took place significantly (p< .001) with ageing. 3) The most preferred out wear was suit & tie and next was jumper or shirt. 4) For the mode of getting suit, the highest number 55.3%) purchased ready-to-wear, next (32.0%) was tailored and the least (12.7%) neither purchased nor tailored. The percentage of buying ready-to-wear significantly (p< .01) decreased with ageing. The main reason for getting tailor-made was not well fitting of ready-to-wear (20.7% out of 32.0%). And for the mode of getting suit, there was significant differance with income (p< .001) and pocket money (p< .01). 5) The most important factors in suit and shirt werefirst, size (fitness) and second, comfort in movement. 6) For the wearing feeling of suit, 55.3% showed discomfort. There was significant difference according to the age (p< .05) and pocket money (p< .05). The Discomfort increased with ageing and less pocket money. 7) 62.4% answered it uneasy to Pick out well fitting If comfortable suit. This showed their dissatisfaction with ready-to-wear. 8) As for the items of not well fitting, 64.4% answered in jacket, 60.8% in trousers, 46.0% in shirt. The above result shows that elderly men's somatotype changes as they age, suit is found uncomfortable and it's not easy for elders to pick out comfortable ready-to-wear. So, they seem to have a certain dissatisfaction in ready to wear. Therefore, there is a need for reorganization of size and developing pattern design according to measurement of elderly men.

Objectives : To evaluate the properness and effectiveness of the question categories concerning 'sasang constitutional characteristics of mind', used in Iksan Wonkwang Oriental Medicine. Methods : We statistically analyzed data from those 1335 patients focussing on 'relative discrimination ability' to sasang constructions and 'response ratio'. Patients included in this research are only those who had been well treated in Iksan Wonkwang Oriental Medicine during the Period of three years from 2000 to 2002. The data are obtained through the electronic chart developed by Kim Jong-Yeal, and analyzed using the statistical Package SPSS. Results: In total characteristics of mind, the question category of 'timid' has high discriminating power and effectiveness to Soeum type, more in women than men, and especially with an age of 21 or more; The category of 'hasty-tempered' to Soyang type in women with all ages and men with ages 21-40; The category of 'broad-minded' to Taeum type with ages 41 or more; The category of 'timid and broad-minded' to Soyang type, and especially high to women with ages 41 or more. Question categories concerning response type in anger were estimated to have different response patterns to sasang constructions only for ages 21 or more by $X^2$2 test. The question category of 'bear and last long' has high discriminating power and effectiveness to Soeum type, more in men than women, and increasingly to ages; The category of 'impatient and disarmed quickly' to Soyang type in both women and men, especially with ages 21 or more; The category of 'impatient' to Soyang type women or with ages 21 or more. Other categories have low discriminating power or low effectiveness. Concernig expression type of one's thought, the question category of 'straightly' has high discriminating power and effectiveness to Soyang type, more in wemen than men, and especially to ages 21 or more; The category of 'tender' to Soeum type, in women or with ages 40 or less; The category of 'indirectly' to Taeum type in men or with ages 41 or more; The category of 'straightly and stuborn' to Soyang type with ages 41 or more; The category of 'indirectly and tender' to Soeum with with ages 20 or less; The category of 'not express and tender' to Soeum type with ages 41 or more; Conclusions : Question categories concerning total characteristics of mind, response type in anger and expression type of one's thought, are partially discriminating and effective to specific constitution according to sex and ages, and some categories are more discriminating and effective when they are composited. But generally, the discriminating power of Taeum constitution group and group with ages 20 or less was too low, so it is necessary to develope question categories for those groups.
