Objectives This study was designed to investigate the correlation between the forward head posture and the spinal alignment. Methods We examined the whole spine x-rays of the 144 student sample. We measured the Craniovertebral angle (CVA), Cervical angle (CA), Thoracic kyphotic angle (TKA), lumbar lordosis angle (LLA) and Ferguson's angle (FA) of the students. We then analyzed the relationship between these angles. Results CVA had correlation with CA, but it was weak. There was significant correlation between CVA and TKA. There were no significant correlation among CVA, LLA and FA. Conclusions According to above results, there is a negative relationship between the CVA and the TKA - in that higher CVAs yielded lower TKAs. But CVA had no significant correlation with LLA or FA.

Objective: To evaluate the extent and aspect of stress to the cortical bone after application of a lateral force to a two-component orthodontic mini-implant (OMI, mini-implant) by using three-dimensional finite element analysis (FEA). Methods: The 3D-finite element models consisted of the maxilla, maxillary first molars, second premolars, and OMIs. The screw part of the OMI had a diameter of 1.8 mm and length of 8.5 mm and was placed between the roots of the upper second premolar and the first molar. The cortical bone thickness was set to 1 mm. The head part of the OMI was available in 3 sizes: 1 mm, 2 mm, and 3 mm. After a 2 N lateral force was applied to the center of the head part, the stress distribution and magnitude were analyzed using FEA. Results: When the head part of the OMI was friction fitted (tapped into place) into the inserted screw part, the stress was uniformly distributed over the surface where the head part was inserted. The extent of the minimum principal stress suggested that the length of the head part was proportionate with the amount of stress to the cortical bone; the stress varied between 10.84 and 15.33 MPa. Conclusions: These results suggest that the stress level at the cortical bone around the OMI does not have a detrimental influence on physiologic bone remodeling.

Objectives : Regulatory T cells can reduce inflammation and allergic reactions through their inhibitory functions. Gardeniae Fructus(GF) is a Heat-clearing herb used in traditional Korean medicine, and a wide range of studies on its antiinflammatory effects are being carried out. The authors investigated the effect that Gardeniae Fructus has on regulatory T cells. Methods : The authors screened 14 herbs for their effects on regulatory T cells. 100mg of each herb were separately dissolved in 1ml of sterile saline and the supernatant was harvested after 10 minutes of centrifuge at 15,000 rpm. The supernatant was filtered through a 0.2 ${\mu}m$ syringe filter, and the resulting stock was refrigerated at $4^{\circ}C$. The stock was diluted before testing and used at a final concentration of $0.01{\mu}g/ml$. CD4+CD25+ T cells from healthy BALB/c spleens were used as natural regulatory T cells (nTreg), and CD4+CD25- T cells were used as reactive T cells. CD4+CD25+ and CD4+CD25- T cells were activated with anti-CD3e ($10{\mu}g/m{\ell}$)/anti-CD28 ($1{\mu}g/m{\ell}$) and cultured. IL-10 from supernatant of the culture medium was measured by IL-10 cytokine ELISA. The percentages, cell numbers, phenotype and function of CD4+CD25+ Treg cells were determined by flow cytometry. Results : Gardeniae Fructus was shown to be the most potent herb among the 14 herbs tested for suppressing CD4+CD25- reactive T cell proliferation by stimulating CD4+CD25+ natural regulatory T cells. Gardeniae Fructus induces IL-10 secretion increase by stimulating CD4+CD25+ natural regulatory T cells, and indirectly suppresses CD4+CD25- reactive T cell proliferation through increasing CD25 (IL-2 receptor $\alpha$) expression and thus promoting bonding with IL-2. Gardeniae Fructus did not directly affect CD4+CD25- reactive T cell proliferation. Conclusions : Gardeniae Fructus suppressed reactive T cell proliferation through inducing increases in IL-10 secretion and CD25 (IL-2 receptor $\alpha$) expression.

We examined the effects of temperature on acquisition of Potato virus Y-O (PVY-O), Potato virus A (PVA), and Potato leafroll virus (PLRV) by Myzus persicae by performing transmission tests with aphids that acquired each virus at different temperatures. Infection by PVY-O/PVA and PLRV increased with increasing plant temperature in Nicotiana benthamiana and Physalis floridana, respectively, after being transmitted by aphids that acquired them within a temperature range of $10-20^{\circ}C$. However, infection rates subsequently decreased. Direct qRT-PCR of RNA extracted from a single aphid showed that PLRV infection increased in the $10-20^{\circ}C$ range, but this trend also declined shortly thereafter. We examined the effect of temperature on establishment of virus infection. The greatest number of plants became infected when N. benthamiana was held at $20^{\circ}C$ after inoculation with PVY-O or PVA. The largest number of P. floridana plants became infected with PLRV when the plants were maintained at $25^{\circ}C$. PLRV levels were highest in P. floridana kept at $20-25^{\circ}C$. These results indicate that the optimum temperatures for proliferation of PVY-O/PVA and PLRV differed. Western blot analysis showed that accumulations of PVY-O and PVA coat proteins (CPs) were lower at $10^{\circ}C$ or $15^{\circ}C$ than at $20^{\circ}C$ during early infection. However, accumulation increased over time. At $25^{\circ}C$ or $30^{\circ}C$, the CPs of both viruses accumulated during early infection but disappeared as time passed. Our results suggest that symptom attenuation and reduction of PVY-O and PVA CP accumulation at higher temperatures appear to be attributable to increased RNA silencing.

Three-hundred samples of powdered infant formula milk and related products from four different manufacturers in 2010 were collected and surveyed their contaminations for aerobic bacteria, coliform, Enterobacter(Cronobacter) sakazakii, and food-borne pathogens. Fifteen samples of sterilized infant formula milk were all negative on these microorganisms. In all collected products of un sterilized infant formulas and follow-on infant formulas, aerobic bacteria were detected at 239 (83.9%) among 285 samples, and they all were found below $10^3$ cfu/g. Coliform bacteria were also detected at four among 285 samples. Salmonella spp. and Ent. sakazakii, weren't detected at the all samples. Bacillus cereus was detected at 24 (8.4%) among 285 samples. The level of B. cereus was below 100 cfu/g but it was suitable for the range of specification of B. cereus in infant formulas. Clostridium perjringens, Escherichia coli O157:H7, Staphylococcus aureus and Listeria monocytogenes weren't also detected. In consequence, it was suitable for total viable count, coliform and potential pathogen to the specification of infant formulas and related products.

Objectives : The purpose of this study is to explore the trends of Korean medical study on stress in the industrial worker. Methods : We received numbers of the studies about stress in the industrial worker from 6 Korean web databases, using key words such as 'Industry AND Stress', 'Oriental medicine AND Stress', 'Worker AND Stress', 'Workplace AND Stress'. We received 12 research papers and they were analyzed and the journals, the authors, the contents of 3 classification of those research papers. Results : Among them, we had 6 reviews of Dept. of preventive medicine and Dept. of third medicine, college of Korean Medicine, Won-kwang University, and the rest of them were 6 reviews. We had 4 reviews of Korean Journal of Oriental Preventive Medical Society, 2 reviews of the Journal of Traditional Korean Medicine, 2 reviews of Journal of Oriental Neuropsychiatry and so on. According to the contents of reviews, we had 7 reviews of correlation of industrial worker and stress, 4 reviews of cause on the industrial worker's stress and 1 case report. Conclusions : We reviewed the trends of Korean medical study on stress in the industrial worker. The stress in the industrial workers were related with the type of occupation, social psychology, drinking, smoking, the satisfaction of job, the harmony of organization. And we knew that the musculoskeletal pain was related to the industrial worker's stress. In the future, abundant case studies, follow-up trials and RCTs should be done about the industrial worker's stress.
