The purpose of this study is to investigate the drinking patterns and behaviors of Yangsan College students. Data were collected by a self-administered survey from the subjects, of which male students were 336 and female 165. The results of this study were as follows: 1. With regard to attitude toward drinking, 93.1% of the male subjects and 84.3% female subjects reported to have favor for drinking while only 9.3% of the subjects against drinking. 2. Those who reported to have at least a drink everyday were 13.3% of the subjects. For drinking frequency subjects who reported once in two or three day were most popular(21.9%). The frequency of drinking alcohol was associated positively with amount of discretionary money the students have. 3. For amount of drinking, 42.5% of subjects responded that they were able to drink soju at least one bottle per occasion. Data showed a high positive correlation between drinking frequency and financial costs they spent to drink. 4. The reasons subjects gave to drink included social gatherings after school or student activities (40.1%), change of mood(16.5%), and personal cerebration(16.5%). 5. The most popular place for the subject to go for a drink was neighborhood pubs(43.5%), followed by bar or pubs at downtown(28.3%) and nearby campus(12.2%).

Purpose: The purpose of this study was to investigate the work conditions, reported stress, role conflict and job satisfaction of infection control nurses working in general hospitals. Methods: The subjects were 125 infection control nurses from 102 general hospitals. Data were collected using a questionnaire consisting of questions about general characteristics, job characteristics, work condition, stress, role conflict, and job satisfaction. Data were collected from July to September 2011 and analyzed by descriptive statistics, independent t-test, one-way ANOVA, Scheffe test, Pearson's correlation, and Stepwise multiple regression in SPSS/WIN 18.0. Results: Over fifty percent (56.0%) of infection control nurses reported the majority of their time was monitoring intensive units. The average reported stress was 7.20, role conflict was 3.67, and job satisfaction was 3.14. The factors which influenced job satisfaction were stress, enough information, annual income, and the number of hospital beds. Conclusion: The factors contributing to job stress of infection control nurses need to be specifically identified. Education and training for infection control personnel should be provided to enhance job satisfaction.

The MRI (magnetic resonance imaging) volumetric analysis of the brain was performed in 59 healthy elderly Koreans (aged 62-76 years; 34 male, 25 female) to investigate whether the previously reported significant correlations between body height and brain volumes in the young aged Koreans (20's) still exist in the old aged Koreans (60's and 70's). Unlike previously reported significant correlations in the young aged Koreans, neither the correlation between whole brain volume and body height in male nor the correlation between cerebellar volume and body height in female show any significance in the old aged Koreans. The significant correlation between body height and whole brain volume was still observed when both male and female data were combined (r=0.27, P<0.05), but the correlation coef-ficient and the level of significance markedly decreased from those of previously reported Korean youth data (r=0.67, P<0.01). Simple linear regression analysis shows decrease of explanatory power of height (measured in $r^2$) from 44% in the youth group to 7% in the old age group on the variance of whole brain volume. Multiple linear regression analysis shows that age and sex, rather than height, are major explanatory variables for whole brain volume in the old aged Koreans. The loss of correlations in the aged group is suspected to be mainly due to age related brain volume changes.

Objectives: The purpose of this study was to investigate estheticians' self-reported pain symptoms and pain levels according to the parts of the hand. Methods: Data were collected through a questionnaire survey among 116 estheticians from 31 skin care centers and spas. Information about general characteristics, job characteristics and work characteristics were based on data from the self-administered questionnaire. To determine the self-reported pain symptoms and pain levels according to the parts of the hand, a Cornell Musculoskeletal Discomfort Questionnaire was used. Results: The subjects had the greatest self-reported pain symptoms in the thumb(Right: 53.4%, Left: 46.6%) and felt the highest level of pain in the wrist(Right: 4.87 points, Left: 4.71 points). Physical burdens and age had statistically significant effects on the pain level in the right hand, while physical burdens and the manager rather than the director had statistically significant effects on the pain level in the left hand. Conclusions: Since the thumb and wrist have the greatest subjective pain symptoms in the hand, the use of proper tools is recommended in order to reduce the usage of the thumbs during massage, as is regular stretching to protect the wrists.

Purpose: To investigate the prevalence of smoking behavior among elementary students which may serve as basic data for developing a smoking prevention program. Method: Questionnaires were given to 734 fourth, fifth, and sixth graders in five elementary schools in U county, North Chungcheong Province. Data were collected from 8 to 20 December, 2003; and analyzed using SPSS/PC for descriptive and chi-square statistics. Result: Of these students, 19.9％ reported that they had smoked and 0.8％ answered they are current smokers. They reported that the first smoking started during third grade (26.0％), at their homes (38.4％), and out of curiosity (74.0％). They reported severe coughing when they first smoked (56.2％). Smoking experiences were significantly related to grade, gender, and academic performance. Similarly, environmental characteristics such as residential area, parental status, father's job, parental attention, home atmosphere, and smoking siblings or friends were significantly related to smoking behavior. Among non-smokers, 86.4％ intended not to smoke and 1.4％ would like to smoke in the future. Conclusion: Certain school and environmental characteristics were associated with smoking experimentation. Therefore teachers and parents should use this information to develop and guide smoking prevention programs.

Detailed pulse shape analysis of a Geiger-$M{\ddot{u}}ller$ counter is performed to understand the pulse shape dependence on operating voltage. New data is presented to demonstrate that not all pulses generated in a GM counter are identical. In fact, there is a strong correlation between the operating voltage and the pulse shape. Similar to detector deadtime, pulse shapes fall in three distinct regions. For low voltage region, where deadtime was reported to reduce with increasing voltage, pulse generated in this region was observed to have a fixed pulse width with a variable tail. The pulse width and fall time of the tail was observed to be a function of applied voltage; exponentially reducing with increasing voltage with an exponent of negative 6E-04 and 2E-03 respectively. The second region showed a pulse without any significant tail. During this time the detector deadtime was earlier reported to be at its minimum. The highest voltage region demonstrated a different deadtime mechanism where the second pulse was reduced in width. During this time the deadtime seemed to be increasing with increasing voltage. This data allows us to gain some unique insight into the phenomenon of GM detector deadtime not reported thus far.

Pteris griffithii Hook., one of the rarest fern species on the Indian subcontinent, is reported from Bhutan for the first time. The identity of this species was confirmed through morphological determination at the National Herbarium (THIM) of the National Biodiversity Centre (NBC) of Bhutan. It was found only in one location, in Gyelpozhing in eastern Bhutan, at an elevation of 521 m a.s.l. on 10 January 2016. Given that a very limited study of this species was conducted, the knowledge baseline with regard to its distribution is poor. It is also reported that this species has not been found for several years. The species is also considered to be very rare or critically endangered in some countries; however, there are no assessments on the International Union for Conservation of Nature (IUCN) Red List for this particular species. This paper attempts to provide baseline information considering its rarity and data deficiency. This species is also reported from the adjacent neighboring Indian state of Arunachal Pradesh as very rare, and also from Myanmar; however, confirmation of its presence in China is not clear at this time. Therefore, considering its data deficient status, we attempt to document it scientifically to create a knowledgebase pertaining to this particular species. Concurrently, this species merits further research to understand its distribution patterns in Bhutan and any related anthropogenic threats.

The Purposes of this study were to assess high school students' nutrient consumption at the ordinary time and to analyze nutrient contents and nutrition consumption of lunch. The questionnaires for self-reported food consumption were distributed to 210 students enrolled in a boy's high school and a girl's high school located in Seoul area. A final response rate was 87.1%, excluding responses that had significant missing data. Data of self-reported food consumption and BMI(Body Mass Index) were analyzed with descriptive analysis and t-test using SPSS Win(ver. 12.0). To measure the serving size and the waste amount, data were collected for three meals in a three day period at each school. A weighed plate method was employed to measure plate wastes and consumption of the menus served. Nutrient analyses for the served and consumed menus were performed using CAN-PRO. The result of nutrient intake determined by self-reported food consumption demonstrated 74.2% of boys and 70.0% of the girls did not meet EAR(Estimated Average Requirement) for calcium. In addition, the data collection showed that 60.2% boys and 26.7% girls did not consume EAR for Vitamin B$_1$. Nutrient analyses of the served and consumed menus at school lunch were compared with 1/3 of the Dietary Reference Intakes(DRIs) for this age group. The served menus did not meet 1/3 of the Recommended Intake(RI) for calcium, iron, and vitamin B$_2$. In contrast, the menu provided to students exceeded almost five times(490%) more than the sodium needed for 1/3 of the Adequate Intake(AI). Considering the amount of the students' plate waste, intake of vitamin A and vitamin C were below 1/3 of the RI, and calcium, iron, and vitamin B$_2$ intake were also reduced. Students' sodium consumption still exceeded 1/3 of the AI at 340.0%.

The tris(hydroxymethyl)aminomethane (Tris)-catalyzed hydrolysis of p-nitrotrifluoroacetanilide was kinetically studied. On the contrary to the previously reported results (R. M. Pollack and T. C.Dumsha, J. Am. Chem. Soc., 1973, 95, 4463), the dependence of the rate on [Tris] consists of an initial curve portion and a subsequent linear increase. This indicates that erroneous conclusions were made in the reported work due to the insufficient amount of data. The initial portions of the rate[Tris] profiles are attributed to the catalyzed breakdown of the tetrahedral intermediate, and the linear portions to the general base-catalyzed water attack at the substrate.
