In this study, the eating out behavior and recognition of salinity in restaurant food in Jecheon area were examined. Demographic characteristics of the subjects, eating out behavior and perception of salinity in food purchased in restaurants were surveyed. Also salinity of the high Na-containing menus were measured using salimeter. Exactly 51.6% of the study subjects usually ate out more than one to two times per week. A large percentage (88.6%) of the subjects mentioned that they ate more than half the amount of liquid in their dishes. The study participants recognized that the salt concentrations of stews, soups and noodles in their orders were high. JJamppong was recognized as the most salty among nine kinds of eating out menus, whereas mulnaengmyeon was the least. Although the recognized salt concentration of mulnaengmyeon was relatively low, this dish had the highest salinity out of nine eating out menus. Relative salinities of eating out menus were higher than absolute salinity mostly except yukgaejang. It is necessary to supply exact nutrition information and widely implement nutrition labeling. Furthermore, consumers should personally be careful to limit consuming food with high sodium levels when dining at restaurants and eat less liquid in dishes.

Objective: The purpose of this study was to analyze the effects of club head and golf ball kinematics and body alignment according to the swing plane during golf driver swing. Method: Sixteen college golfers participated in this study. Kinematic data of the club head and golf ball were collected using golf swing analysis system (Trackman Ver. 3e). The body alignment variables were collected using 8 motion capture system. An Independent samples t-test was used for comparison between the Out-to-In group and In-to-Out group, and the statistical significance level was set at .05. Results: For the club head related variables, club path and club face angle showed higher values in Out-to-In swing plane than In-to-Out swing plane. For the kinematic variables of the golf ball, the total distance showed a higher value in the In-to-Out swing plane than that of the Out-to-In swing plane. For the body alignment, the In-to-Out swing plane showed higher values than the Out-to-In swing plane for the pelvis rotation angle and trunk rotation angle. Conclusion: This study suggest that it would be more effective to use the In-to-Out swing plane for increasing the total distance during the golf driver swing.

Purpose: Except for continuous suture in skin layer, stitching out in facial laceration, we have to hold each knots up and cut the knots by No. 11 blade or small scissors. However, we often have difficulty in stitching out the knots on children who do not cooperate well. Therefore we introduce an easy and fast stitch out method of pediatric lacerations. Methods: From January to May 2009, we studied 15 pediatric patients (mean age 5.6 years old) who had facial laceration on face or underwent any surgery on operation room. For easy stitch out, we left the one string of the first knot long enough to extend at the opposite end of laceration site. And then the extended string was fixed to skin using Steri-strip. Next we do simple interrupted suture including the extended traction nylon string inside the knot. Through this method, we can stitch out all knots simply by lifting up the traction nylon needless to hold the each knot one by one. Results: Until stitching out, the traction nylon was just right position and there was no normal tissue injury during stitch out all knots. Patients were satisfied with the short stitch out time. Conclusion: By using the traction nylon on pediatric laceration suture, we can stitch out all the knots with no normal tissue injury in less time.

This experimental study was carried out to evaluate the improvement of rural privys and to develop the system of the three septic tank privy. For this study, 42 samples of excreta, 42 samples of soil and 26 samples of vegetables were drawn out of the conventional privys while 26samples of excreta, 26samples of soil and 26samples of vegetables out of the three septic tank privys from five villages in Chun Song County. Kang Won Province for the period from 22th August to 13th October, 1984. The major findings are as follows : 1. Positive cases of helminthes are found 41 out of 42(97.6%) excreta of the conventional privys whereas those from the three septic tank privys are found 2 out of 26 (7.7%). Average numbers of helminthes from the excreta of the conventional privys are 4.4 whereas those from the three septic tank privys are 1.1. 2. Positive cases of helminthes are found 33 out of 42 (78.6%) soil of the conventional privys whereas those from the three septic tank privys are found 20 out of 26(76.9%). However, this difference does not reveal statistical significance (P>0.01). Average numbers of helminthes from the soil of the conventional privys are 2.3 whereas those from the three septic tank privys are 1.7 and the difference in total number of helminthes reveals statistical significance (P<0.05). 3. Positive cases of helminthes from vegetable samples drawn out of the conventional privys are found 13 out of 26(50.0%) whereas those froin the three septic tank ptivys are found 10 out of 26(38.5%). Average numbers of helminthes from vegetable samples drawn out of the conventional privys are 1.1 whereas those from the three septic tank privys are 0.7. However, these differences in both positive rates and total numbers of helminthes do not reveal statistical significance (P>0.05).

This study was aimed to establish the evaluating protocol and standard assessment for genetically modified (GM) hot pepper and to find out a proper statistic method to analyze for equality of agricultural characters between GM and non-GM pepper lines. GM and non-GM hot pepper lines were cultivated in two GMO fields in the middle region of Korea and total of 52 agricultural characters were collected during the plant growing season for 4 years, 2007 to 2010. Levene's test was conducted to confirm the homogeneity of raw data before statistic analysis. Two-way ANOVA in the multivariate tests and t-test were conducted to analyze 52 agricultural characters in order to find out the equality between H15 and P2377. From the statistical analysis through two-way ANOVA, 16 out of 16 plant growth traits, 9 out of 18 green fruit traits and 7 out of 18 red fruit traits among 4 years and 9 out of 16 plant growth traits, 4 out of 18 green fruit traits and 3 out of 18 red fruit traits between H15 and P2377 have shown the statistic differences. With the same raw data of 52 agricultural characters, t-test was also conducted. Based on the result from t-test, only 1 out of 16 plant growth traits, 2 out of 18 green fruit traits and 1 out of 18 red fruit traits have shown the differences between H15 and P2377, so that it was concluded that there is no statistic difference between H15 and P2377 in terms of agricultural characters. Also, the t-test is a proper statistic method to analyze each trait between GM and its control lines in order to evaluate agricultural characters.

This study was to find out the effects of out-of-class environmental experience learning on elementary students' environmental literacy. For this study, we developed and applied environmental education program utilizing out-of-class facilities and ecological park for the 5th-grade students. The subjects of this study were the 5th grade students of an elementary school located in Si-hung city. The study was carried out for two groups, an experiment group of 29 students and control group of 29 students. The education program using out-of-class environmental experience learning was provided to the experiment group while lecture-oriented education program was provided to the control group. The questionnaire used in this study to assess the environmental literacy of the study objects consists of 41 questions under 4 domains (knowledge, emotion, skill, behavior). After observing and analyzing the effects of out-of-class environmental experience learning on students' environmental literacy, we found that the program using the out-of-class environmental experience learning posed greater impacts than lecture-oriented program. By domains, environmental literacy in 3 domains illustrated positive improvement. In particular, skill domain illustrated much more improvement in environmental literacy. But, domain of behavior didn't illustrated improvement in environmental literacy. The result of this study signified that the out-of-class environmental experience learning has positive and effective impact on the environmental literacy. And out-of-class environmental experience learning is more suitable to improve the skill domain of the environmental literacy than lecture-oriented learning. But, it is couldn't improve the domain of behavior. Therefore, in order to improve behavior domain, the program must apply with effective evaluation and home training.

Through a questionnaire survey of 607 respondents over 20 years old currently residing in Seoul, general conditions, items and amount of daily diet, preference of dining-out and instant food, and concern for health were surveyed and the results are as follows. A large portion of respondents, at 36.2% of all respondents, were 20 years old, 57.7% of them graduated from high school or over, and most of them(61.9%) were over middle-class level of living standard. More than half (50.9%) of whom paid less than 10% for dining-out took breakfast as a rule, and 38.3% of whom regularly took meals and 37.3% of them took their regular daily routines. But among whom spent more than 31% for dining-out 46.2% of them took snacks between meals every day. Also, among whom spent more then 31% for dining-out, about 25.6% of them usually dined out every day. On concerns for health, among whom spent less than 10% of dining-out expense, 53.9% of them took exercise almost every day and 32.8% for 30 minutes, and 34.6% of them were generally healthy and 67.5% of them had normal blood pressure. But among whom spent more than 31% for dining-out expenses, 10.3% of them were not healthy, 15.4% had higher blood pressure and 20.5% had lower blood pressure, thus those portion were relatively higher compared with the former group. From those research results, therefore, group who spent lower dining-out expenses were older people with lower educational and living level but regularly took breakfast and exercise. Thus, their daily schedules were routine and took regular meals with healthy condition. The group with lower dining-out expense took right food pattern and kept healthy condition, and, therefore, it implied that dining-out gave significant influence to food pattern of grown-ups. Therefore, nutrition education for grown-ups might be necessary again and our foods as a diet should be re-evaluated and re-highlighted. To formulate the practical nutrition education in early childhood, practical, systematic, and continuous nutrition education might be required and effective and multidimensional education programs should be developed. In addition, various menus of breakfast with diverse materials, wide range of nutrition, and being convenient and time-saving must be studied in the near future.
