Background : Recently the demand was increasing on the data describing treatment rates and the outcome of Androgenetic Alopecia using Oriental Medicine. Thus this study was designed to observe androgenetic Alopecia treatment using Oriental Medicine including acupuncture and herb because there has been no such statistics. Objectives : Our purpose was determine whether oriental medicine treatment leads to clinical improvement in men with androgenetic alopecia. Methods : Eighty two Men, 17 to 53 years of age, with male pattern hair loss according to a modified Norwood/Hamilton classification scale(II to VI) were enrolled in this study. Patients were treated with multidisciplinary Korean oriental medicine treatment (herbal acupuncture, acupuncture, herb, chuna therapy) at twice a week for 6 months to 12 months. Efficacy was evaluated by patient and investigator assessment, and global photographic review. Results : Oriental medicine treatment improved scalp hair by all evaluation. Patient self assessment demonstrated that Oriental medicine treatment slowed hair loss, increased hair growth, and improvement appearance of hair. These improvements were corroborated by investigator assessments and assessments of photographs. Conclusion : Oriental medicine treatment has significant effects on the androgenetic alopecia. Longer follow up studies are needed to examine whether its effects last long enough for the patients with androgenetic alopecia.

Purpose: The purpose of this study was to compare variables related to weight control between normal weight and overweight/obese female adolescents. Methods: This study is a supplementary analysis using a total of 293 female adolescents in Seoul. Data were collected through self-report questionnaires on the topics of stages of change, processes of change, and the decisional balance pertaining to weight control. Body weight and height were also measured. Results: There was a significant difference in the stages of change between the normal weight and overweight/obese groups. Of 12 processes of change, 9 processes were significantly higher in the overweight/obese group than in the normal weight groups. Also, female adolescents who were overweight or obese had significantly higher pros and eating efficacy scores comparing to those in the normal weight group. Conclusion: The findings of this study suggest that overweight/obese female adolescents, especially those in the action stage need supports to continue their weight control behaviors. In addition, a weight control program for female adolescents should emphasize their participation in physical activities in addition to their dietary control efforts.

The present study aimed to prepare a novel efficient flame retardant additive for polypropylene. The new flame retardant was prepared by chemical grafting of melamine to graphene oxide with the aid of thionyl chloride. Fourier-transform infrared spectroscopy and thermogravimetric analysis proved that melamine had been successfully grafted to the graphene oxide. The modified graphene oxide was incorporated into polypropylene via solution mixing followed by anti-solvent precipitatio. Homogeneous distribution as well as exfoliation of the nanoplatelets in the polymer matrix was observed using transmission electron microscopy. Thermogravimetric analysis showed a significant improvement in the thermo-oxidative stability of the polymer after incorporating 2 wt% of the modified graphene oxide. The modified graphene oxide also enhanced the limiting oxygen index of the polymer. However, the amount of improvement was not enough for the polymer to be ranked as a self-extinguishing material. Cone calorimetry showed that incorporating 2 wt% of the modified graphene oxide lowered total heat release and the average production rate of carbon monoxide during burning of the polymer by as much as 40 and 35%, respectively. Hence, it was concluded that the new flame retardant can retard burning of the polymer efficiently and profoundly reduce suffocation risk of exposure to burning polymer byproducts.

Objectives: This study was performed to evaluate the consumer education program for reducing sodium intake based on social cognitive theory (SCT) and investigate consumer perceptions of environmental, cognitive and behavioral factors. Methods: Consumers (n=4,439) were recruited nationwide in Korea to participate in a nutrition education program for reducing sodium intake which was targeted on senior housewives (SH), parents (P), and office workers (OW). Questions regarding main factors of SCT were asked both before and after the education program. Results: SH and P recognized external social efforts and information to reduce sodium including nutrition labeling more than OW. The main barriers to practice reducing sodium intake were limited choice of low sodium food and menu, interference with social relationship when dining with others, and limited information, knowledge and skills. SH had lower barriers to practice reducing sodium intake and OW perceived 'preference to soup or stew' and 'preference to Kimchi, salted fish and fermented sauces' as barriers more than other groups at the baseline. Less than 50% of participants knew the relationship between sodium and salt, sodium in nutrition labeling, and recommended sodium intake. In addition, OW had little knowledge for capability to reduce sodium intake and lower self-efficacy to practice compared with SH and P. After education, positive outcome expectations such as lowering blood pressure, prevention of cardiovascular disease and osteoporosis were increased and barriers to practice reducing sodium intake were decreased in all groups (p < 0.05). The knowledge for behavioral capability and self-efficacy to reduce sodium intake were also improved but OW had still lower scores compared with other groups. Conclusions: These results suggested that nutrition education programs could be an effective tool to impact general population by facilitating awareness and increased capability to reduce sodium intake.

The purpose of this study is to identify the factors that influence users' intention to use mobile services in academic libraries, based on the Davis' Technology Acceptance Model. This study employed both perceived usefulness and perceived ease of use, which were core variables in TAM, and added perceived playfulness that was recently applied to many researches on mobile system acceptance intention. As external variables, ubiquitous ability, context awareness, and mobile internet self-efficacy were employed. The data was collected from 325 surveys from two academic libraries and was analyzed with SPSS 18.0 and AMOS 21.0. As a result, perceived usefulness was the most significant factor in predicting users' acceptance intention and perceived ease of use was an indirect determinant of service usage. But perceived playfulness was not significantly correlated. Ubiquitous ability among external variables had a significant effect on perceived usefulness, context awareness did on both perceived playfulness and ease of use, and mobile internet self-efficacy did on perceived ease of use. Based on the findings, this study discussed theoretical and practical implications in academic library mobile service area.
