Objective : The main purpose of this study was to analyze factors affecting a health related quality of life(HRQOL) in the elderly stroke patients with(Group 1) or without(Group 2) sequela. Methods : This survey performed secondary analysis with 'the fifth korea national health and nutrition examination survey', and investigated 91 elderly stroke patients over 65 years. Results : The results were as followed: HRQOL and self rated health had a significantly lower in Group 1(p<.05). In all groups, HRQOL was affected by self rated health(${\beta}=0.39$), mental health, and medical health significantly(p<.05). In group 1, HRQOL was affected by mental health(${\beta}=0.45$), self rated health significantly(p<.05). In group 2, HRQOL was affected by medical health(${\beta}=0.45$), functional health, mental health significantly(p<.05). Conclusion : In order to improve the HRQOL of stroke patients during rehabilitative therapy, it is important that early detection and early intervention of depression and suicide, which affect mental health status, are important in the case of severe aftereffects. If the patient continues to support his/her current status regardless of aftereffects, he/she can improve the HRQOL with functional recovery of the stroke patient, and finally have a positive effect on the independence of the stroke patients.

This study was carried out to suitable plantation site from comparison and analysis of regional early growth characteristics of planted Larix kaempferi trees in harvested L. kaempferi plantations. Two-year-old bare-root seedlings of L. kaempferi were planted with the density of $3000\;seedlings\;ha^{-1}$ at four sites (Yeongju, Gimcheon, Chuncheon, and Inje). All sites were established with three plots ($400m^2$ per plot) in 2010. We analyzed soil physical and chemical properties in October 2010 and 2013. We measured root collar diameter (RCD) and height of trees in October from 2010 to 2014, and then calculated H/D ratio and stem volume. Soil pH was significantly increased and available P was significantly decreased 3 years after planting. Annual mean RCD, height, and stem volume of 5-to 7-year-old in the Chuncheon site were significantly higher than those in the other sites, however them in the Yeongju site were the lowest. It is related to the fact that total nitrogen, available phosphorus, and organic matter concentrations in the Yeongju site were relatively lower than those in the other sites. As a results of this study, we could confirm the correlation between soil properties of L. kaempferi plantations and growth of L. kaempferi trees. We could suggest values of soil properties for reforestation of L. kaempferi.

This study was peformed in order to find out the relationship between the causing factors and the production of each gas 01 oral malodor, to contribute the oral malodor control at dental clinic as well as to establish the effective application of malodor control project for public oral health program 127 patients from 20 to 40 years old who had been visited for preventive dental cares were participated for the study. Such items as caries status, periodontal status, salivary flow, viscosity, pH. Snyder test, plaque deposit and tongue plaque were checked through the oral examination in order to find out the contributing factors Hydrogen sulfide, Methyl mercaptan, Di-methyl sulfide and Ammonia gas components were checked with Oral-Chroma and Attain, the oral malodor check units. Not only the corelation coefficiencies but also the multi-way variance analysis were calculated between each causing factor and each component of oral malodor gases to estimate the contributing factors of the oral malodor. 1. There was no relationship between the caries status and each component pf the oral malodor such as sulfur compound or Ammonia, both in laboratory test and VAS test (pF0.05). It revealed negative relationship between Hydrogen sulfide and FT(rM-0.1904. pE0.05) as well as the VAS and FT (rM-0.210. pE0.05). S0, it was estimated that the less oral malador was recognized when caries state changed to filled state in Hydrogen sulfide laboratory test or VAS test 2. High relationship was showed between salivary flow and Hydrogen sulfide (rM-0.183, pM0.039), Methyl mercaptan(rM-0.234, p-0.008). Dimethyl sulfide(rM-0.234, pM0.008) and Ammonia(-0.361. pM0.001) gas(pE0.05). 3. There was a high relationship between M-PHP(Modified-Patient Hygiene Performance Index) and tong plaque all kinds of sulfide(rM0.249. pM0.005). Ammonia gas component(rM0.232, pM0.009). 4. It was found that considerable relationship was appeared between the periodontal status and Ammonia gas (rM0.274, pM0.002), so, it should be needed to control Ammonia. Such dental Cares as the prevention or early treatment of periodontal disease and the accelerating the salivary flow as well as reducing the amounts and activities of filament or spiral typed oral micro-organism were recommended for adults, not only for dental care program at the dental clinics but also for public health programs, in order to promote the oral health and quality of file for individual and community peoples.

This study evaluated the perception, school stress, psychological factors, and association of students in middle and high school groups in terms of their BMI (Body Mass Index). The '2010 Korea Youth Health Survey 'was used to study data 7187 people. The subjects were classified into the underweight group (BMI < 20), normal group (BMI 20 - 24), overweight group (BMI of 25-29), and obese group (BMI of 30 or higher). The subjects found to have experienced smoking were as follows: underweight BMI group (17.2%), normal weight group (18.4%), overweight group (21.8%), and obese group (25.8%) (p=0.016). The level of satisfaction was as follows: $14.24{\pm}3.15$ for the normal weight group, $13.67{\pm}3.13$ for the overweight, and $12.84{\pm}3.72$ in the obese group. The normal-weight group had a higher level of satisfaction (p=0.005). Underweight, normal, overweight, and obese BMI group were at school for an average of $33.57{\pm}5.76$, $33.45{\pm}5.50$, $33.12{\pm}5.34$, and $32.21{\pm}7.43$ hours per week, respectively (p=0.044). Therefore, the development of social misfit youths needs to be managed properly and effectively to improve their physical and mental health. Industry, academia and government need to collaborate with programs to achieve this aim.

In this study, nano-micelled curcumin was produced with natural sea salt with a view to comparing the in silico molecular binding affinity of pure curcumin compound to the active site of transthyretin. Using an optical light microscope and an electron microscope, it was found that the structure of the surface and the cross-section of nano-micelled curcumin was significantly different from natural sea salt. In particular, the crystal structure and nano-components in the nano-micelled curcumin were united, and the layer was more strongly stabilized than untreated salts. In the virtual 3D structure, in silico molecular docking study, the ligand binding affinity of nano-micelled curcumin to the transthyretin active site was found to be higher than that of pure curcumin. In addition, a nano-micelled curcumin formula interacted with more amino acid residues of transthyretin domains. The pharmacophore feature of the nano-micelled curcumin also showed more condensed and constrained features than normal curcumin. These results suggest that nano-micelled curcumin may effectively bind to and stabilize transthyretin, thereby regulating transthyretin-related physiological diseases. Collectively, the nano-micelled curcumin process suggests that normal curcumin can be modified more efficiently into the novel bio-functional chemical formula to stabilize the transthyretin structure. Therefore, the nano-micelled curcumin process can be applied to the field of the regulation of Alzheimer's disease.

The analytical measurement range (AMR) is the range of analyte values that a method can directly measure on a specimen without any dilution, concentration, or other pretreatment not part of the usual assay process. The linearity of the AMR is its ability to obtain test results which are directly proportional to the concentration of analyte in the sample from the upper and lower limit of the AMR. The AMR validation is the process of confirming that the assay system will correctly recover the concentration or activity of the analyte over the AMR. The test specimen must have analyte values which, at a minimum, are near the low, midpoint, and high values of the AMR. The AMR must be revalidated at least every six months, at changes in major system components, and when a complete change in reagents for a procesure is introduced; unless the laboratory can demonstrate that changing the reagent lot number does not affect the range used to report patient test results. The AMR linearity was total protein (0-16.6), albumin (0-8.1), total bilirubin (0-18.1), alkaline phosphatase (0-1244.3), aspartate aminotransferase (0-1527.9), alanine aminotransferase (0-1107.9), gamma glutamyl transpeptidase (0-1527.7), creatine kinase (0-1666.6), lactate dehydrogenase (0-1342), high density lipoprotein cholesterol (0.3-154.3), sodium (35.4-309), creatinine (0-19.2), blood urea nitrogen (0.5-206.2), uric acid (0-23.9), total cholesterol (-0.3-510), triglycerides (0.7-539.6), glucose (0-672.7), amylase (0-1595.3), calcium (0-23.9), inorganic phosphorus (0.03-17.0), potassium (0.1-116.5), chloride (3.3-278.7). We are sure that materials for the AMR affect the evaluation of the upper limit of the AMR in the process system.

This study investigated the improved lipid metabolism effect of 3T3-L1 cells induced by adipocytes using the dichloromethane (DCM) fraction in the organic solvent extract of Wassong (Orostachys japonicus). To confirm the cell cytotoxicity, each of 6 fractions of organic solvent extracts (EtOH, Hexane, DCM, EtOAc, BuOH, and H₂O) was examined using MTS assay. As a result, it was confirmed that the DCM extract was stable over the whole range of concentrations, and a DCM fraction was used to confirm the improved lipid metabolism effect. Lipid excretion was measured to confirm the change of lipid metabolism. 3T3-L1 cells induced by adipocytes were treated with DCM extract and stained with oil-red O to evaluate lipid accumulation. As a result, it was confirmed that the lipid efflux was significantly improved. In order to confirm the mechanism of lipid efflux, the mRNA expressions of ABCA1 and ABCG1, which are lipid transport proteins, were confirmed by real-time PCR. Therefore, the present study confirmed that the DCM extract from Orostachys japonicus has the effect of improving the lipid metabolism on 3T3-L1 adipocytes. In addition, the results of this study will be used as the basis for the development of functional foods using Orostachys japonicus and also for conducting research on the detailed mechanisms.

The purpose of this study is to emphasis the fact that the oral cavity should be well-managed as it is where the intake of the valuable nutrition for the baby is made, among many other important factors and changes that the pregnant women go through as they prepare for the birth of a human being for 10 months. For this, we surveyed the management of the oral hygiene and the awareness of oral health by the pregnant women. The result showed that the nauseating during the brushing of the teeth and the use of the oral hygienic products varied among different standard of lives with statistical significance. As for the standard of living, those in higher level showed also a higher level of the use, while the middle and low standard of living showed lower level of usage of the oral hygienic products. In case of the dental treatment during the pregnancy, most of the interviewees answered they do not receive dental treatment during pregnancy in the fear of bad influence on the baby and the potential risk of congenital anomaly. The perceived necessity of the education on the oral health was generally high. And, for the contents of such education, they preferred the timing of the dental treatment, the content of the treatment, and misunderstandings regarding the dental treatment.

The objective of this study was to reduce Nuruk flavor in Korean rice-distilled liquor using different ratios of $Sumizyme^{TM}$ and Nuruk. After 9 days of fermentation at $28^{\circ}C$, alcohol contents and pH were 16.0~17.1% and 3.82~4.16, respectively. An increased ratio of $Sumizyme^{TM}$ decreased alcohol content while increased pH of the mash. In alcohol contents, there were no significant differences up to 30% substitution of Nuruk to $Sumizyme^{TM}$. A descriptive analysis was conducted with trained panelists for determining the intensity of Nuruk flavor. The intensities of Nuruk flavor in mashes and distilled liquors brewed by traditional Nuruk, cultured Nuruk, and a mixture of 30% $Sumizyme^{TM}$ and 70% cultured Nuruk were evaluated. The mash and distilled liquor prepared using a mixture of 30% $Sumizyme^{TM}$ and 70% cultured Nuruk showed significantly lower intensities of Nuruk flavor when compared with those of mashes and distilled liquors produced by the traditional and cultured Nuruk.
