  • The primary purpose of this research was to examine Korean childrens concepts of authority. Childrens judgments about commands of persons with varying age, social position, and knowledge were assessed. 48 subjects from the first, third, and fifth grades were presented with portrayals of persons giving children commands regarding two types of events: fighting and a game rule dispute. Subjects evaluated the legitimacy of commands and chose between different persons giving opposing commands. With regard to a command to stop fighting, subjects accepted the legitimacy of adult and peer authorities, as well as an adult without a position of authority. Subjects rejected commands that failed to prevent harm even when given by an adult authority. With regard to a game rule dispute, subjects most heavily weighted knowledge in evaluating the authority commands. The findings show that Korean children do not have a unitary orientation to adult authority, and have implications for an understanding of individuals' conceptions in the context of a cultural ideology emphasizing reverence for authority.

  • This research analyzed the hematological index and health related habits such as alcohol drinking, smoking and exercise, by classifying 539 middle-aged men (age: 40 - 59) into a normal weight group, an overweight group and an obese group, according to BMI (body mass index). As a result, 33.6% (n = 181) of subjects had a BMI of 23 or less and 30.2% (n = 163) were overweight and 36.2% (n = 195) were obese (BMI > 25). The average systolic/diastolic blood pressures of total subjects were 130.96mmHg and 80.38mmHg, respectively. And the average pressure of normal subjects was 126.85/77.57mmHg, which was significantly lower than in overweight and obese subjects. Diastolic blood pressure shows significant differences among the three groups. The overall average cholesterol level of normal subjects was 193.81mg/dl, which was significantly lower than those in overweight subjects. Those in obese subjects were significantly higher than in overweight subjects. The GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyrutic transaminase), ${\gamma}$-GTP (gamma-glutamyl transpeptidase) levels of obese subjects were significantly higher than in the overweight subjects. Frequency of alcohol drinking showed no significant difference among the groups. The smoking ratio in the obese group was higher than in the normal and overweight groups. The ratio of smokers was 53.1 %, and the alcohol drinking ratio was 81.0% of the total subjects. The frequency of drinking showed significant correlations with systolic blood pressure (p < 0.05) and diastolic blood pressures (p < 0.01) and ${\gamma}$-GTP (p < 0.01). The duration of smoking showed a negative correlation (p < 0.01) with diastolic blood pressure, total cholesterol and ${\gamma}$-GTP. On the other hand, exercising frequency showed negative correlations with blood glucose, ${\gamma}$-GTP and GPT(p < 0.01). These hematological indices were correlated with health related habits such as alcohol drinking, smoking and lack of exercise, and to be the cause of chronic diseases. Therefore, proper nutritional education is needed to establish advisable health related habits to maintain proper body weight. (J Community Nutrition 8(2): 63-68, 2006)

  • This study compared the effects of the initial head position (i.e., a HHP versus a relaxed head position) of subjects with and without a FHP on the thickness of the deep and superficial neck flexor muscles during CCF. The study recruited 6 subjects with a FHP and 10 subjects without a FHP. The subjects performed CCF in two different head positions: a HHP, with the head aligned so that the forehead and chin formed a horizontal line, and a relaxed head position (RHP), with the head aligned in a self-selected comfortable position. During the CCF exercise, the thickness of the longus colli (LCo) and the thickness of the sternocleidomastoid (SCM) were recorded using ultrasonography. The thickness of each muscle was measured by Image J software. The statistical analysis was performed with a two-way mixed-model analysis of variance. The thickness of the SCM differed significantly (p<.05) between the subjects with and without FHP. According to a post $h^{\circ}C$ independent t-test, the change in thickness of the SCM increased significantly during CCF in the subjects with FHP while adopting a HHP compared to that in the subjects without FHP. The change in thickness of the SCM was not significantly different between the two positions in subjects without FHP, and there was no significant change in thickness of the LCo muscle during the CCF exercise according to the initial position in both subjects with and without FHP. The results suggest that CCF should be performed in RHP to minimize contraction of the SCM in subjects with a FHP.

  • This study was carried out to investigate the eating behaviors and the preferences of industrial workers in Korea. This survey was conducted from May 20 to June 20, 1998 by constructed questionnaires and the subjects were 364 males and 588 females. The results obtained were summarized as follows: 1) The subjects who didn't have breakfast regularly were 41.7% because they didn't have enough time to eat. The main type of breakfast were cooked rice. 2) The subjects who used the company cafeteria were 60.5% and men used the company cafeteria more than women. The most favorite side dishes by the subjects were roasted foods and next side dishes were seasoned foods. There were not significantly different the kinds of favorite side dishes between men and women. The main reason that the subjects preferred to a specific side dish was 'delicious'. 3) Foods and dishes that the subjects could approached frequently and easily made the eating habits changed. The most favorite meal types of the subjects were Korean foods because those were good taste for the subjects. The favorite snacks by men were ramyon and those by women were rolled rice(Gimbab). 4) The pan-fried foods(Jun) were the most favorite food in the cloudy day and the salads were the most favorite food in the sunny day. The most favorite taste of the subjects were light and clear tastes and next favorite taste of the subjects was salty tastes. This study shows that the eating habit of industrial workers could be changed by easily and frequently approached food and weather. In addition, the lacks of time was main reason that the subjects couldn't have regular breakfast. Therefore, it needs to develop the desirable programs and diet menus to consider the situation of the industrial workers and weather.

  • The mathematics education circles in Japan has a variety of subjects. I want to speak w generally are considered on those subjects. Some of these subjects are as follows: (1) The ratio of students who go on to high schools is about 95 percent, so that it is h to solve how to design the mathematics curriculum for the poor scholars. (2) Though the effects of instruction at the schools does not betray the nation's trust, JUKU increase in number. Thus all teachers in schools cannot but endeavor to fulfil the responsibility. (3) Some of the junior high school's teachers suffer from the misconducts and violences pupils. Thus researchers of mathematics education in such schools tend to stagnate. 4) The tudents and pupils get good results in the examinations of calculation, but in the examinations such as word problems that require their judgements not so. Etc. t is not easy to solve or cope with the these subjects. or the subjects as (3), all teachers concentrate their efforts on the activation of lessons the heightening the pupil's will to learn. or the subjects as (4), the idea of mathematical thinking has be advocated since about 1960, recently the 'problem solving' are proposed and are studying. Lastly the researchers in the university are theorizing their own works and digest and utilize arge foreign's literatures. Furthermore a great number of teachers make an effort to research their calssrooms. But a great part of the results of their researches are utilized only in country. I hope, hereafter, that the effects of researches in Japan become known and ized to the foreign countries.

  • The purpose of this research was made to suggest the improvement for problems of indication subject of Fisheries & Maritime High School teacher's certificate issued by the operation of the 7th national curriculum in 2000. After analyzing the integrated indication subjects related with fisheries & Maritime high school, among the middle school teacher's 24 subjects of industrial world, the problems and improvements can be arranged as followed. Firstly, the subjects of fisheries & Maritime high school teacher's certificates are fishing industry, aquiculture, sailing, engine and freezing and new subjects are ocean shipping and ocean logistics. Because the teacher's certificate was changed to integrated indication subjects, there were problems of teacher cultivation, teacher hiring, etc. So, in the actual field of school, teacher cultivating university and related department are necessary to strengthen high-quality majoring education/subjects and practical education as well as need to establish teacher cultivating system by teacher cultivating organization's evaluation system and teacher cultivating education program related by differentiation and easiness of majoring characterization. Secondly, teacher cultivating for new departments and new subjects can apply related major system, free major system, etc. Thirdly, if professional high schools find majoring areas whose content is same one another and introduce common indication subject system, it will be helpful to improve the quality of teachers, teacher certification examination, etc. of professional area.
