Purpose: The purpose of this study were to investigate the health status and to identify the influencing factors on health status by gender among service workers. Method: Data were collected from the self-reported survey of 781 service workers in sales, food & lodging industry. The data were analyzed by descriptive statistics and multiple linear regression analysis using SPSS Win 10.0. Result: The influencing factors of male workers' health status were job satisfaction, standing hour during work time, physical work environment, job demand and family support. The influencing factors of female workers' health status were job satisfaction, emotional labor, physical work environment, regular exercise, standing hour during work time, social support and age. Conclusion: Gender specific occupational Health program for service workers should be developed in consideration of these influencing factors.

The methanolic extract of the roots of Lithospermum erythrorhizon (Boraginaceae) was found to show inhibitory activity towards farnesyl protein transferase (FPTase). Bioassay-guided fractionation of the methanolic extract resulted in the isolation of three naphthoquinone compounds, as inhibitors of FPTase. These compounds inhibited the FPTase activity in a dose-dependent manner.

School violence is known to cause various emotional, behavioral and social problems. Low self-esteem, lack of self consciousness, sense of alienation, guilty consciousness, somatoform symptoms and low concentration happened to adolescent victims. This patient was suffering for school violence during about a year, then Pain disorder occurred to him. Neurofeedback has been used as a complementary therapeutic relaxation and a increasing self-esteem technique. This patient, is a 13-year- boy, who had been exposed school violence for a year and caused severe and constant pain, was successfully treated by Neurofeedback therapy with oriental medication. This case report is focused on treatment through these methods.

The vector pCW5 with plasmid pC7, originally isolated in Lactobacillus paraplantarum C7 derived from kimchi, was constructed using a p32 strong promoter, the pC7 replicon, and green fluorescent protein (GFP) as the reporter. The constructed vector was transformed into E. coli and Leuconostoc mesenteroides, and GFP expression detected using a Western blot analysis. GFP fluorescence was recognized in E. coli and Leuconostoc mesenteroides using a confocal microscope. In addition, GFP fluorescence was also clearly detected in several industrially important lactic acid bacteria (LAB), including Lactobacillus bulgaricus, Lactobacillus paraplantarum, and Lactobacillus plantarum. Thus, pCW5 was shown to be effective for Leuconostoc mesenteroides when using GFP as the reporter, and it can also be used as a broad-host-range vector for other lactic acid bacteria.

Using both experimental and theoretical approaches, we have investigated the adsorption properties of an organic molecule (HATCN), which is used in OLEDs as an efficient hole injection layer, on metal and inert surfaces. We have also studied the structural and electronic properties of such interfaces and the dependences on deposition thickness. We have observed different trends in work function changes with different surfaces. Our photoelectron spectroscopic measurements have revealed an abnormal phenomenon in HATCN on a metal (Cu) surface: the work function decreases at lower coverage (~monolayer) of HATCN on a metal (Cu) surface, but it increases back and becomes higher than that of a bare Cu surface at higher coverage. It has, on the contrary, been observed that the work function of graphene surface just increases as the HATCN coverage increases. Our first-principles density functional calculations has not only verified our experimental observations, but also disclosed the underlying mechanism of such abnormal and different work function behaviors. We have found that the change in work function results from mutual polarization induced by the geometrical deformation and the bond dipole formed at the interface due to the charge redistribution. At low coverage of HAT-CN on Cu substrate, the former reduces the work function significantly by pulling down the vacuum level, while the latter tends to push up the vacuum level resulting in the work function increase.

Two lignan glycoside compounds were isolated from the twigs of Vaccinium oldhami (Ericaceae) through repeated column chromatography. Their chemical structures were elucidated as lyoniside and ssioriside, respectively, by spectroscopic analysis.
