Purpose: This study examined gender differences on Musculoskeletal disease (MSD) medical status, the characteristics of the approved patients in workers, and the factors affected approval. Methods: Claim data for the MSD to the Korea Worker's Compensation & Welfare Services (2011) were employed. The medical status by gender was analyzed using t-test, chi square-test and multivariate logistic regression models. Results: The number of claims for MSD has continuously increased in females but not in males since 2006. The severity measured by the care duration, surgery experience and disability grade has been substantially higher in males than in females. Age, size of company, types of occupation, work duration and the weight of materials handled daily were associated with the approval. When males were considered, the work duration, the weight of materials handled daily and parts of the body were statistically significant predictors of approval in males. In case of female, there were meaningful predictors in types of industry and parts of the body. Conclusion: These findings suggest that gender-specific risk factors of MSD should be measured and the management program for MSD should be developed.

The objectives of this study were to classify the contents of clothing image preferences of Korean and American students, and to examine how clothing image preferences vary according to sex role identity, sex, and culture. A woman's clothing image preference inventory and the Bem Sex Role Inventory were administered to 127 Korean students and 116 American students. Sex role idendity was classified into androgynous, masculine, feminine, and undifferentiated type. 1. Four segments of woman's clothing image preference derived by factor analysis : F. 1 'splendid-plain' ; F. 2 'feminine-masculine' ; F. 3 'casual-formal' ; F. 4 'classic-contemporary'. 2. Americans prefered splendid image more than did Koreans. Androgynous-typed males liked splendid image most among American male subjects. 3. There was interaction effect between sex and culture on feminine-masculine image preference. In Korean students, males liked feminine image much more than did females. Masculine-typed females liked masculine image most among American female subjects. 4. Koreans prefered casual image more than did Americans. 5. There was interaction effect between sex role identity, sex, and culture($4{\times}2{\times}2$) on classic-contemporary image preference. Feminine-typed females liked classic image most among Korean female subjects. 6. Korean males especially prefered luxurious image least. Korean females contemporary most, American males sexy most, American females fashionable most among four subject groups. That is, differences on clothing image preferences were found according to sex role identity, sex, and culture.

Assessment of speech nasality provides important information for the treatment of velopharyngeal incompetence. Objective procedures may be used to assess velopharyngea1 function, in examples Nasometer, Aerodynamics, x-ray, Electromyography, Nasoendoscopy and Videofluoroscopy etc. The aim of this study was to obtain comprehensive nasalance data for Korean adults, aged 20 years and to investigate any gender differences within that age group using Nasometer II. The results were as follow: (1) The nasalance of the vowels(/a/, /i/, /e/, /o/, /u/, /ja/, /je/, /wi/) in the group of adults was higher in females than in males (p<0.05). (2) The nasalance of the plosives (/p/, /$p^h$/, /p'/, /t/, /$t^h$/, /t'/, /k/, /$k^h$/, /k'/) in the group of adults was higher in females than in males (p<0.05). (3) The nasalance of the affricatives (/c/, /$c^h$/, /c'/) in the group of adults was higher in females than in males (p<0.05). (4) The nasalance of the fricatives (/s/, /s'/, /$\int$/) in the group of adults was higher in female than in males (p<0.05). (5) There was no statistically significant effect for the nasalance of nasal consonants (/m/, /n/, /$a{\eta}$/).

Common dermatophytosis in upper Egypt were studied at three hospitals in Minia city. Tinea corporis (ringworm of glabrous skin) was diagnosed in 127 patients (84 males and 53 females). Trichophyton was the most common genus and was represented by 6 species among which T. violaceum was the commonest fungus. Microsporum was represented by 4 species and M. canis was the prevalent species. Tinea pedis (ringworm of the foot) was noticed in 22 cases (13 males and 9 females) and also Trichophyton and Microsporum were the causal organisms. Three species of Trichophyton namely: T. violaceum, T. kuryngei and Trichophyton sp. were isolated. Tinea cruis (ringworm of the groin) was diagnosed in 21 patients (16 males and 5 females). Epidermophyton floccosum was the most prevalent fungus associated with tinea cruris whereas Trichophyton and Candida were less frequent. Tinea unguium (ringworm of the nail) was diagnosed in 9 patients, 8 were females and one was male and the age incidence ranged between 5 and 55 years. M. canis occurred in 2 cases and T. mentagrophytes in one case. Out of 86 cases of tinea versicolor, 71 were males and 15 were females. Malassezia furfur was the main causal agent. All patients of candidiasis and paronychia were females and Candida was the most prevalent causal agent.

The bush warblers (Cettia diphone) have been recognized to possess two types of songs: a normal song that plays roles in attracting mate and territorial defense, and an anomalous song. The present study suggests that the anomalous song functions as an alarm signal as well as other unknown signals. Field observations and playback experiments on the anomalous song of bush warbler were conducted in order to investigate the contextual information that occurred between sender and receiver. In the field observation, the males frequently emitted anomalous songs to potential predators. The males responded with an anomalous song to stuffed potential predators. The distance from where the anomalous song occurs to the stimulating source varied depending upon the kinds of stimulus. The males of bush warbler possibly show different responses to the anomalous song depending on the level of danger. When the anomalous song was played back to terrestrial males and females, no distinctive behavior was observed. The anomalous song may be sung to defend the territory against predators or to distract invaders from the nest and female because the male and female behaviors were related with the anomalous song and its phonetic characteristics.

The purpose of this study is to analyze the level of obesity and sarcopenia among chronic obstructive pulmonary disease(COPD) patients in Korea. The current study recruited 75 patients with COPD who visited the department of respiratory medicine at J University Hospital in J-do. Height, body weight, waist circumference, and hip circumference were measured, and body composition, muscle strength, and flexibility were assessed. The levels of obesity were classified with body mass index(BMI), waist-hip circumference ratio(WHR) and percent body fat, and sarcopenia was classified with the value of skeletal muscle mass and muscle strength by Asian Working Group for Sarcopenia. In results, it was found that the level of obesity was very high as 43% by BMI, 88% by WHR, and 64% by percent body fat. The lower level of muscle strength was 15.50% in males and 23.50% in females. The lower level of muscle mass was 24.10% in males and .00% in females. Males who had one sarcopenia factors were 22.40%, and females were 23.50%, respectively. Males with sarcopenia were 6.90%, and females were .00%. In conclusion, regular resistance exercise is essential not only for the development of motor skills, but also for the normalization of skeletal muscle function and prevention of muscle dystrophy among COPD patients.

This study investigates the gender differences in determinants of customers' satisfaction when purchasing online beauty and cosmetics products in Vietnamese market. To do so, we construct a data set via online survey of 419 Vietnamese customers including both males and females, and examine such sample using t-tests and multiple regressions. Our regression model is constructed based on our five-construct model including online shopping experience, customer service, external incentives, security and privacy, and personal characteristics. The t-tests results reveal that the mean difference of customer satisfaction (negative coefficient) between the two groups of customers (females and males) is statistically significant. This suggests that the purchasing satisfaction of male customers is significantly higher than that of their female counterparts. Similarly, we also find that male customers are more satisfied with their online shopping experience, customer service and external incentives offered by the online sellers than female peers. Furthermore, regression results for full sample show that, on average, the online shopping experience, customer service and external incentives are significantly and positively related to customer satisfaction. Yet, such positive effect of customer service on customer satisfaction is more likely for males while females' satisfaction is more positively influenced by security and privacy.
