This study analyzes the difference in total cholesterol blood concentration according to dietary characteristics and health characteristics, as well as general characteristics, and the relationship between that factor and total cholesterol level according to the diagnostic criteria for dyslipidemia, and then compares and analyzes the relative risk ratio of significant factors for the occurrence of dyslipidemia. As a result, the total cholesterol blood concentration increases with age, so continuous management is necessary. Mainly, waist circumference level in early adulthood, regular exercise of appropriate intensity in late adulthood, and subjective health level management in the elderly are necessary. It was found that it was necessary to manage BMI level and eating-out level overall.

As the importance of health and school health grows, the purposes of this research are to investigate the differences between the characteristics and the utilization of the nurse's office of an elementary school in an urban area and the nurse's office of an elementary school in a rural area, and to provide the data for the planning of construction of a nurse's office convenient for students to use after grasping the regional characteristics. The methods of this research include the interview and the survey conducted to the heath teachers after visiting 20 nurse's offices in 13 eups and myeons, and examined and analyzed the differences between the characteristics and the utilization of the nurse's office of elementary schools in an urban area and the nurse's office of an elementary school. The nurse's offices of the elementary schools in Cheongwon, a rural area, are worse in access to health care institutions and in the connection to the placement than those of the elementary schools in urban areas, so most of eups and myeons were not allowed for easy access to medical service. Depending on the bad personal surroundings of each elementary student, mental stress and the lack of heal care of each student should be taken care of along with the educating of the parents and the children. Also because of the difficulties in access to the health care institutions, it is suggested that a lot of support and interest should be provided for the nurse's offices and that a lot of changes with functions should occur to the nurse's offices so that the nurse's office of an elementary school can play the role as a local health care institution. Besides, the health teachers also should be able to provide more professional medical services by taking in-service training courses.

The purpose of this study was to investigate the anthropometric and blood biochemical characteristics, the dietary behaviors and health-related lifestyles of obese children in Incheon. A cross-sectional survey was conducted using anthropometric measurements, biochemical assessments and questionnaire analysis. The subjects included 7,055 obese children residing in the Incheon area (from 106 elementary schools). The degree of obesity was classified using the Obesity Index (OI) as light 20% ＜ OI ＜ 30% ; Medium 30% ＜ OI ＜ 50% ; Severe 50% ＞ OI. The statistical analysis was conducted using SPSS 10.0 program. Most subjects fell within the medium range of obesity. Most subjects had dietary problems such as overeating, unbalanced meals and skipping breakfast. The ratio of boy subjects eating green and yellow vegetables was lowe. when compared to that of the girl subjects. The boy subjects exercised more frequently and longer than the girls. As the Obesity Index increased, hypercholesterolemia significantly increased. The blood cholesterol levels of the subjects were positively correlated with body fat, waist/hip ratio and BMI; HDL cholesterol levels of the subjects were negatively correlated with the anthropometric data and the LDL cholesterol levels of the subjects were positively correlated with body fat. The blood triglycerides levels of the subjects were positively correlated with body weight, body fat, waist/hip ratio and BMI. Therefore, proper nutritional education and intervention are required for an improvement of obese children＇s dietary behavior, heath-related factors and blood lipid profiles.

We investigated the physicochemical and antioxidant activity characteristics of tomato porridge with different ratios (0%, 2%, 4%, 6%, and 8%) of tomato powder in order to determine its potential health benefits. Tomato porridge samples were measured to obtain 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging activity. The DPPH radical scavenging activity increased with the addition of tomato powder. The moisture contents of samples ranged from 81% to 78%. The L-value decreased, while a- and b-values increased, as the amount of tomato powder in the porridge increased. Also, the pH of samples decreased with increasing quantity of tomato powder. Based on sensory evaluations, the tomato powder intensified color, flavor, taste, appearance, viscosity and overall acceptability of the porridge. The sample that comprised 6% tomato powder had the highest color, flavor, taste, appearance and overall acceptability scores. Consequently, this research found that incorporating this percentage of tomato powder into the rice flour was the best formula for tomato porridge.

The $(Sr_{1-x}Ca_x)TiO_3$(SCT) thin films are deposited on Pt-coated electrode (Pt/TiN/$SiO_2$/Si) using RF sputtering method with substitutional contents of Ca. The optimum conditions of RF power and Ar/$O_2$ ratio were 140[W] and 80/20, respectively. Deposition rate of SCT thin film was about 18.75[$\AA$/min]. The dielectric constant was increased with increasing the substitutional contents of Ca, while it was decreased if the substitutional contents of Ca exceeded over 15[mol%]. The capacitance characteristics had a stable value within ${\pm}4$[%] in temperature ranges of -80~+90[$^{\circ}C$].

We have investigated the in vitro cytotoxic effect of liposome-encapsulated N-(phospho-nacetyl)-L-aspartic acid (PALA) against C-26 murine colon cancer cells, and have compared it in this regard to free PALA. Three different PALA-containing liposomal formulations using distearoylphosphatidylcholine (DSPC), distearoylphosphatidylglycerol (DSPG), and polyethyle-neglycol-derivatized distearoylphosphatidylethanolamine (PEG-DSPE) were made and their cytotoxicity was measured. In 72 hr continuous exposure experiment with C-26 cells, the 50% growth inhibitory concentration ($IC_50$) of DSPG-PALA liposome formulation was $0.09\mu\$, which showed about 65-fold more potent than unencapsulated free PALA ($5.1\mu\$). Similar degree of increase in cytotoxicity was also observed in 1 hr exposure experiment. However the $IC_50$ of PEG-DSPE-PALA liposome and DSPC-PALA liposome were $10.7\mu\$and $11.8\mu\$respectively, which showed slightly less potent than unencapsulated free PALA. Physical characteristics of PALA-liposomes, such as the size and drug:lipid ratio were also determined. In conclusion, negatively-charged DSPG-PALA liposome showed the highest cytotoxic effect among tested on the C-26 cells in vitro.

Jeju island is located in far from main land and has very harsh environment that has formed an unique clothing style as well. In addition, the popular belief has been developed with originality even their clothing. Therefore, this study is concerned with costumes worn for various ritual events and to analyze their features in Jeju. The shamanism served 18,000 gods are composed to 12 different types of the events for wealth, safety, heath, sadness or thanks. The costumes worn by officiating priests or 'Simbang(shaman)' depend on the occasion of an event, and they are different for male and female performers. The styles of costumes for religious service can be divided into 7 types: Regulation dress(Jebok), Korean full-dress attire(Dopo), Official uniform(Danryung), Military uniform(Gunbok), Formal dress (Durumagi), Casual wears and Special costumes. The costumes for religion events are not various and splendid as compare with another province in Jeju. Because, when simbang expired, their clothings had been burned according to custom. However, It is important materials for us to know the clothing of time. We should keep studing that costume more as a valuable culture.

Objectives: To identify factors affecting the health of male professional soldiers. Methods: Cross-sectional questionnaire data was collected from a randomly stratified sample population of 763 officers and sergeants who were employed in 34 units in the Korean military. Data were statistically analyzed using Chi-square test and multiple logistic regression analysis. Results: Work environment and personal health behavior were influential factors, which were differentiated by recent disease history including cardiovascular disease and self-rated health status. Sergeants in special forces/units or engaged in front-line military activities, and soldiers who were current smokers and heavy drinkers were more likely to have been diagnosed with a disease in the preceding three months. Those who were older, obese, and heavy drinkers were more likely to have cardiovascular disease than those who were less obese and more physical active. Soldiers exhibiting signs of extreme stress were more likely to poorly self-rate their health status. Conclusion: Health behaviors and characteristics of work environment significantly influence the health status among Korean professional soldiers. Health promotion strategies are needed to change individual heath behaviors such as smoking, alcohol consumption, and work stress. A healthier working environment should also be promoted.

Massive multiple-input multiple-output (MIMO) is a promising approach for cellular communication due to its energy efficiency and high achievable data rate. These advantages, however, can be realized only when channel state information (CSI) is available at the transmitter. Since there are many antennas, CSI is too large to feed back without compression. To compress CSI, prior work has applied compressive sensing (CS) techniques and the fact that CSI can be sparsified. The adopted sparsifying bases fail, however, to reflect the spatial correlation and channel conditions or to be feasible in practice. In this paper, we propose a new sparsifying basis that reflects the long-term characteristics of the channel, and needs no change as long as the spatial correlation model does not change. We propose a new reconstruction algorithm for CS, and also suggest dimensionality reduction as a compression method. To feed back compressed CSI in practice, we propose a new codebook for the compressed channel quantization assuming no other-cell interference. Numerical results confirm that the proposed channel feedback mechanisms show better performance in point-to-point (single-user) and point-to-multi-point (multi-user) scenarios.
