This study was performed to investigate relationships among night eating and nutrient intakes status in university students. A total of 271 subjects (male=155, female=116) were divided by using 3-days food record method according to the percentage of energy from night eating: non-night eating, <25% night-eating and ${\geq}25$ night-eating group. There were no significant differences in age, height, weight, percent body fat and BMI among the groups. The proportion of morning anorexia and insomnia was below 2% and 10%, and no differences were observed among the groups by percentage of energy from night eating. In the male subjects, the intakes of energy in the '${\geq}25$ night-eating group' was significantly higher than those of the other groups; whereas, the nutrient density (ND, nutrient intakes per 1,000 kcal) and INQ (index of nutritional quality) of vitamin $B_1$, vitamin $B_2$, vitamin C, calcium and iron in the '${\geq}25$ night-eating group' was significantly lower than those of the other groups. In the female subjects, the intakes of energy in the '<25 night-eating group' was significantly higher than that of the 'non-night eating group'. And the ND and INQ of vitamin C in the '<25 night-eating group' was significantly higher than those of the 'non-night eating group'. In addition, within the male subjects, the INQ of vitamin $B_1$, vitamin $B_2$, vitamin C, calcium and phosphorous showed significantly negative correlations with food intakes, energy intakes and percentages of energy from night eating after the values were adjusted for age. These results suggest that among male university students, night snack intakes above 25% of energy have lower micronutrient qualities of vitamin $B_1$, vitamin $B_2$, vitamin C and calcium.

Purpose: In order to establish efficient palliative treatment plans. It is important to estimate the survival time of a terminally ill cancer patient as accurate as possible. Proper estimation of life expectancy aids not only in improving the quality of life of the patient, it also promotes productive communication between the medical staff and the patient. The aim of this study is to determine the efficacy of neutrophil-lymphocyte ratio as a predictor of survival time in terminally ill cancer patients. Methods: Between January 2004 and June 2007, 67 terminally ill cancer patients who were admitted or transferred for palliative care, were included. Patients were categorized into three groups by Neutrophil-Lymphocyte Ratio. Demographic characteristics, clinical characteristics and blood samples were analyzed. Results: In univariate analysis, survival time of the highest Neutrophil-Lymphocyte Ratio group (${\geq}12.5$) was significantly shorter than that of the others (hazard ratio (HR)=3.270, P=0.001). After adjustment for low performance status (ECOG score 4) and dyspnea, high Neutrophil-Lymphocyte Ratio (${\geq}12.5$) was significantly and independently associated with short survival time (HR=2.907, P=0.007). Neutrophil-Lymphocyte Ratio was also significantly increased before death (P=0.001). Conclusion: Neutrophil-Lymphocyte Ratio can be useful in predicting life expectancy in terminally ill cancer patients.

Recently interactive water fountains are gaining popularity in making public facilities in South Korea. The total number of interactive fountains is rapidly growing at the rate of >50% annually. In this study, we performed quantitative microbial risk assessment to estimate infection risks in children by Legionella spp. while playing in interactive fountains. The exposure dose for a given concentration of Legionella in water was calculated using water-aerosol partition rate of Legionella, exposure duration, inhalation rate, and deposit rate of aerosols in the lungs following inhalation. The dose was converted to infection risk by using the dose-response function developed for L. pneumophila. High weight and/or old children, i.e., 12-year children, running around in fountains were the highest risk group by showing >0.05 infection probability for fountain waters containing ${\geq}10^4$ CFU/L Legionella. The result supported the current guideline by Korea Centers for Disease Control and Prevention, which permits use of water with < $10^3$ CFU/L Legionella cells for all purposes. However, the results still warrant further evaluation of the guideline to accommodate risks for children because the dose-response relationship in the model was developed for healthy adults. Further risk assessment studies need to be conducted by employing dose-response model for children who generally carries weaker immune system than adults.

The purpose of this study is to investigate the relationship between physical fitness factors and academic achievement among high school students. As a research method, cardiopulmonary endurance, flexibility, muscular strength, muscular endurance, quickness, BMI index, and academic achievement of high school students were measured for 641 male and female high school students in 2014 and 2017. The results of this study show that cardiopulmonary endurance is correlated with cardiopulmonary endurance factors (p<0.05), cardiopulmonary endurance is correlated with flexibility and quickness (p<0.05), and flexibility is correlated with academic achievement (p<0.01). Muscle strength was correlated with quickness and body fat (p<0.05), and muscle endurance was correlated with muscle strength, quickness, and BMI (p<0.05), and correlation between quickness (p<0.01), and there was a correlation between academic achievement (p<0.01). The conclusion of this study is that developing and implementing a more effective physical fitness program can contribute to the academic achievement and physical fitness of domestic high school students because various physical activities have a positive relationship with academic achievement in addition to physical fitness.

This study analyzed the effect of forest therapy program on reduction of stress of teachers and their positive and negative emotions based on the survey of 221 teachers who participated in the overnight Happiness School Edu-healing Camp held for teachers by the National Center for Forest Healing. For data analysis, a paired sample t-test was conducted using the SPSS 24.0 program to examine the difference in the stress reaction index of teachers and their positive and negative emotions before and after their participation in the forest therapy program. The results indicated that teachers who participated in the program showed a significant decrease in the stress response index and the values of sub-domain such as physical symptoms, depression symptoms, and anger symptoms. Moreover, all teachers exhibited a significant decrease in stress. This result verifies that the forest therapy program is effective in reducing the stress of teachers and their negative emotions. These results are expected to be used to promote more active forest therapy programs for teachers exposed to a high level of stress.

This study intends to derive play attribute words to describe the nature of play by analyzing the correlation between play facilities and play attribute words. To investigate play attributes at playing facilities and supplement areas of weakness can provide a balanced play environment. Play attributes words were compiled via a literature review and the importance of each play attributes word was surveyed by experts. The keywords explaining play derived from news articles and references are defined as play attributes words. These words were classified into six broad categories and twenty-six sub-categories. The importance of major play attribute words show: Communication (0.268%) > Imagination (0.201%) > Amusement (0.190%) > Development (0.167%) > Learning (0.108%) > Intelligence (0.067%). Experts have recognized the most important elements are communication and imagination. Each play attribute associated with an amusement facility was separately identified in the amusement facilities installed in 114 children's parks in Seoul. Of the play attribute words, the amusement facilities at Seoul's Children's Park reflected a high frequency in 'development'. Furthermore, the importance of major playing attribute words such as 'Communication' and 'Imagination' were not fully reflected in cognitive play facilities. Therefore, it was judged that there is a need to actively introduce these attributes. This study proposed future improvements by determining weaknesses of amusement facilities in children's parks and analyzing the features and functions of play so as to suggest future improvements.

The purpose of this study was to employing MRI in the estimation of the biomechanical body segment parameters of Korean adults. for this purpose MRI study on 19 Korean living subjects were used to measurement. All the parameters that was concerned were inertial characteristics of human body mass of each segment, center of mass of them and the length of radius of gyration of them. The cross sectional images and saggital images of every 1cm interval were got using the 0.5 Tesla MRI from the top of head to the bottom of foot, whole body. And then, by tracing the images of the film and scanning them, got the area which the several tissues occupied in the image of slice. By summing the area of slice of each segment which were calculating and by multipling the density of the tissues, got the mass of segment and other inertial characteristics. The ratios of radius of gyration in both transverse axis and longitudinal axis though the segmental mass and segment length are as follow: male A : head($0.229\pm0.0029$), neck($0.256\pm0.0095$), thorax($0.374\pm0.0059$) abdomen($0.245\pm0.0020$), pelvis($0.368\pm0.0106$), thigh($0.288\pm0.0030$) shank($0.280\pm0.0043$), foot($0.277\pm0.0195$), upperarm($0.311\pm0.0074$) forearm($0.286\pm0.0051$), hand($0.253\pm0.0095$) female A : head($0.214\pm0.0032$), neck($0.254\pm0.0112$), thorax($0.295\pm0.0061$) abdomen($0.289\pm0.0021$), pelvis($0.329\pm0.0108$), thigh($0.288\pm0.0036$) shank($0.280\pm0.0047$), foot($0.243\pm0.0206$), upperarm($0.279\pm0.0083$) forearm($0.286\pm0.0048$), hand($0.229\pm0.0097$) male B : head($0.532\pm0.0006$), neck($0.533\pm0.0006$), thorax($0.658\pm0.0008$) abdomen($1.350\pm0.0022$), pelvis($0.875\pm0.0002$), thigh($0.213\pm0.0001$) shank($0.160\pm0.0001$), foot($0.152\pm0.0002$), upperarm($0.136\pm0.0002$) forearm($0.202\pm0.0002$), hand($0.273\pm0.0006$) female B : head($0.198\pm0.0002$), neck($0.335\pm0.0011$), thorax($0.238\pm0.0001$) abdomen($0.888\pm0.0001$), pelvis($1.318\pm0.0117$), thigh($0.095\pm0.0001$) shank($0.075\pm0.0001$), foot($0.181\pm0.0006$), upperarm($0.0.062\pm0.0001$) forearm($0.083\pm0.0001$), hand($0.105\pm0.0007$).

Powdery mildew of mug bean was found in Suwon on September 2000. Many white and powdery mycelial colonies appeared on leaves of the plants. Conidia with fibrosin bodies were ellipsoid to elongate-ellipsoid, 25~38$\times$16~22 ${\mu}{\textrm}{m}$ in size and farmed in chains. Conidiophores were erect on superfical mycelium, 67~100 ${\mu}{\textrm}{m}$ in length. Foot cells were cylindric with 37~65$\times$10~11 ${\mu}{\textrm}{m}$ in size. Appressoria were indisdinct. Germ tubes from conidia were simple, not branched. Dark brown cleistothecia were observed on the leaves of mung bean. Cleisto-thecia were globose or subglobose, 85~1130 ${\mu}{\textrm}{m}$ in size. Wall cells were irregularly polygonal with 15~45$\times$7~26 ${\mu}{\textrm}{m}$. Appendages were mycelioid, 6-11 per ascocarp, coloured, throught when mature or paler upwards, 1~7 septa, 192~223$\times$5~7 ${\mu}{\textrm}{m}$ in size. A single sun had in a cleistothecium and was ovoid or subglobose with 62~95$\times$50~67 ${\mu}{\textrm}{m}$ in size. Ascusspore had 8 spores in an ascus and rarely developed, mostly imatuna ellipsoid-ovoid with 16~24$\times$12~16 ${\mu}{\textrm}{m}$. On the basis of morphological characters of the conidial stage and teleo-morph, the fungus was identified as Sphaerotheca phaseoli.

Although the sesame lignans, sesamol, have been shown to possess antioxidative activity, less is known about the metabolism and antioxidative properties of sesamol, a major constituent of sesame oil. To determine the ability of sesamol to act as an antioxidant in vivo, we fed rats a diet containing 0.5% sesamol for 3 wk and studied its metabolism and its effects on oxidative stress. Body weight gain and weight of liver, kidneys were significantly higher in the rats fed sesamol than in rats fed the control diets. GST and GST-Px activities in rat liver microsomes were higher in rats fed sesamol and CAT activities were found to be significantly increased in rats fed sesamol. The formation of TBARS was decreased in the liver of rat fed the 0.5% sesamol diet than in controls. We detected sesamol metabolites in liver and kidneys of rats fed sesamol and its metabolites were present as conjugated glucuronides and sulfates. In contrast, not detected sesamol peak in other organs such as colon, small intestine and pancreas.
