The purpose of this study was to investigate the body mass index (BMI), dietary intake attitudes, and nutrient intake status according to sugar-containing food intake frequency of 409 college students in Gyeonggi-do. Subjects were categorized into three groups according to sugar-containing food intake frequency: rare intake group (n=113), average intake group (n=195), and frequent intake group (n=101). The average height and weight (P<0.001) of each group were $163.8{\pm}0.11cm$ and $52.9{\pm}8.6kg$, $164.4{\pm}0.1cm$ and $56.2{\pm}6.4kg$, and $167.9{\pm}0.1cm$ and $68.0{\pm}15.7kg$, respectively. The average BMIs of the groups were $19.6{\pm}2.3$, $20.7{\pm}0.8$, and $24.0{\pm}2.7$, respectively (P<0.001). Dietary intake attitude scores of the groups were $30.73{\pm}5.68$, $30.11{\pm}5.51$, and $28.00{\pm}5.31$, respectively (P<0.001). As a result of nutrient intake status, daily averages of energy and carbohydrate intake of the frequent intake group were significantly higher than those of the rare intake group (P<0.05). On the other hand, vitamin A, vitamin $B_1$, and vitamin C intakes of the rare intake group were significantly higher than those of the frequent intake group (P<0.05). Using multiple regression analysis, we found that BMI was the most significant variable affecting sugar-containing food intake. Therefore, nutrition education is necessary to improve nutrient intake while considering sugar intake for maintenance of healthy weight.

This research involved 226 Jeonbuk Province school dietitians as subjects to investigate intake and perceptions of the healthy functional foods. Sixty nine percent of the school dietitians didn't even know about the law enforcement concerning the health functional foods. Although 68.1% of the respondents said that they slightly knew about health functional foods, only 25% knew exactly what it was. As shown in the survey, most didn't have the cognitive understanding did not understand which should be obtained by education. Sixty two percent of the answerers said they had experience of taking health various functional food products of various kinds such as supplements (57.9%), red ginseng products (52.9%), and chlorella products (30.0%). The motive of intake was in the order of fatigue restoration (25.7%), sickness prevention (22.9%), and nutrient replenishment (22.9%). A fascinating fact from this study was that the reason for healthy functional product intake was different between groups that was primarily interested in the products and those that was not. For those who had interest, the reason for intake was for sickness prevention. On the other hand, for those who didn't have any interest, the reasons was primarily for fatigue restoration and they were mostly persuaded by close friends and relatives. Main concerns were in the order of side effects (4.72), efficacy after intake (4.59), cleanliness (4.51), reliability of the company (4.29), and price (4.23). In view of the study, it is clear that a lot of people are showing interest in healthy functional food products. However, dietitians who are experts in food and nutrition lacked knowledge and information on healthy functional food.

Objectives: This study examines the situation regarding smoking among high school students in Seoul Province and identifies smoking-related factors. Methods: The study sample consisted of 1,000 high school second-grade students from 6 high schools in Seoul. The PRECEDE model was used to assess the students' needs. We carried out an educational diagnosis on attitudes, outcome expectations and social norms. Date were collected from June. 7 to 21, 2011, and were analyzed using SPSS-15.0 according to the study objectives. Results: Of 906 respondents, 9.4% had experiences to smoking: 12.7% were male and 5.7% were female. Smoking-related factors from among general characteristics were statistically significant depending on the degree of gender($x^2$=14.515, p=.001), school performance($x^2$=40.289, p=.001) and friends 'smoking status($x^2$=88.615, p=.001). Factors concerning attitudes toward smoking were statistically significant depending on the students' perceptions as follows: 'Smoking is fun(t=-14.801, p=.000)', 'Smoking looks cool(t=-10.349, p=.000)', 'People who smoke have more friends(t=-11.295, p=.000)', 'Smoking helps me manage stress(t=-15.059, p=.000)' and 'Smoking is not harmful to the body if you exercise(t=-6.388, p=.000)'. Factors concerning outcome expectations were statistically significant depending on their perceptions as follows: 'Tobacco smells good(t=-8.939, p=.000)' and 'Smoking helps in weight management (t=-7.304, p=.000)'. Factors concerning social norms were statistically significant depending on the following perception: 'My friends will not like it if I smoke(t=4.605, p=.000)'. The following influence high school students attitudes toward smoking: School performance (OR=11.66, 95%CI=1.67~81.37; OR=18.27, 95%CI=2.58~129.24; OR=26.74, 95%CI=3.06~233.79), Friends smoking status(OR=80.05, 95%CI=6.94~922.77), 'Smoking is fun(OR=12.90, 95%CI=3.87~43.04; OR=63.41, 95%CI=10.66~377.09)', 'Smoking looks cool(OR=0.15, 95%CI=0.03~0.64)', 'Smoking is not harmful to the body if you exercise(OR=1.44, 95%CI=0.03~0.62)', 'When there is no work to do, smoking is a good way to pass the time(OR=21.68, 95%CI=4.27~109.90)', 'When you are angry, smoking calms you down.(OR=13.39, 95%CI=3.92~45.65; OR=8.69, 95%CI=1.67~45.13)' and 'My parents consider it important that I do not smoke(OR=10.05, 95%CI=1.00~100.43)'. Conclusions: The study suggests that effective ways to discourage of high school students from smoking are changing their attitudes toward smoking, reducing the motivation to smoke, and controlling the number of cigarettes. Therefore, aiming at preventive education. Schools must provide accurate information about the effects of smoking. Thus, health education should actively involve preventive education not only in schools but also at home, the societal and national levels. Cooperation between various sectors of society is required for this.

In this study, a survey was conducted to check the health status and health-related behavior according to the subjective oral malodor of some university students targeting 1,490 students who are attending N university in Cheonan. Based on the result to confirm the awareness of oral malodor and systemic diseases status, there were many cases to be realized such as sinus infection, chronic rhinitis, asthma, gastrointestinal disorders and xerostama among the people who think that they have bad breath, not the people who think that they don't have bad breath (p<.05). Based on the result to confirm the subjective oral health condition according to awareness of oral malodor status, it was shown that there were more respondents who have some oral conditions such as 'there are tooth to be treated', 'there is food stuck between tooth' and 'the gums are often swollen' among the people who realize that they have bad breath, not the people who think that they don't have bad breath (p<.05). It was shown that there were more cases to be brushed teeth everyday among the people who realize that they don't have bad breath than the people who think that they have bad breath (p<.05) and there were more cases to be used dental floss and to be brushed tongue everyday among the people who think that they don't have bad breath (p<.01).

The object is that this research searches the relationship of the office given condition actual condition of the country important facility private security guard and job satisfaction degree. In order to grasp and analyze the real state of the country important facility private security guards directly, the questionnaire, that is the general measurement tool, was utilized and the guard whom it works in the airport, the port region and general work place, that is the national important facility of Busan and Ulsan area, was aimed at. The enough survey object was illustrated to the facility and person in charge in the security company and the item was previewed and the total 400 sheets was distributed and 331 sheets (82.8%) except the doubleness subject intention and incongruent questionnaire was utilized for the analysis. The statistic processing of collected data utilized the SPSS version 15.0 the statistical package program through data coding and cleaning process and performed the frequency analysis, reliability analysis, t-test, one way analysis of variance, Pearson analysis, and regression analysis. The relationship of the office given condition actual condition of the guard about the national important facility and job satisfaction degree was classified into the interpersonal relationship, task characteristic, office environment, and complement factor and the difference of the job satisfaction degree according to the general characteristic was verified. If the conclusion obtained through the method of study described in the above looked at, for as to general tendency, the low wages and poor field environment was continued. In the general characteristic, the man was higher than the excitation about the job satisfaction level. As there was lots of the age and the scholarship was low, the age was high. And as there was lots of the career and income, the police of a petition or search and guide staff was high and the job satisfaction degree in which relatively the employee and the other job group is high so that the case of being the former student incidence can be the poorest was shown rather than the facility security agent. As the interrelation analysis result job satisfaction was high, the change of occupation pseudo was low and the organizational commitment degrees was increased. The regression analysis result job satisfaction degree was exposed to reach the meaningful effect on the change of occupation pseudo and organizational commitment. It had an effect on the change of occupation pseudo as the task characteristic and office ambient level was low. It had an effect on the organizational commitment as the extend of satisfaction about the task characteristic and interpersonal relationship, complement, and office ambient level were high. If the research result of this time is integrated, the support of the political system including the interpersonal relationship thesis between top and bottom of the organized I and substantial complement actualization is urgently needed between the office given condition improvement effort in the country important facility defense manpower field and police of a petition and special guard.

Mathematical, verbal, and spatial abilities are known as three important indicators for the success in the STEM disciplines. In this study, Purdue Spatial Visualization Test-Rotation, College Entrance Scholastic Aptitude Test- Math and Verbal score of engineering freshmen students have been used to find the relationships among these areas. In addition, gender differences in spatial visualization, verbal achievement and mathematical achievement have been investigated, too. In this research, I found that gender difference was highest in spatial visualization ability, followed by verbal achievement and smallest in mathematical achievement. Substantial number of male students possess high level of spatial abilities, but only half of female students were at the same level where their male colleagues were. The correlation between spatial ability and mathematical ability was negligible, contrary to former researches on elementary and middle school students. But the correlation was stronger for female students than male students. The correlation between mathematical achievement and verbal achievement was negative. It reflects the fact that when one section of SAT score is low, score of other sections should be higher to get admitted to college. Gender difference in mathematics was smallest for high achieving spatial ability group. For low spatial ability group gender difference in mathematics achievement has been observed, too. To find the combined contribution of spatial and verbal abilities to mathematics achievement, students were divided into 4 ability groups. Mathematics achievement decreased in the order of (1) high spatial -low verbal group, (2) low spatial - low verbal group, (3) high spatial - high verbal group, (4) low spatial - high verbal group.

Purpose: Koreans' internet and smartphone usage hours are steadily increasing and the dependence of young people on smartphones is causing social problems. Therefore, this study was conducted to examine health and dietary habits, as well as hair mineral contents according to the level of dependence of smartphone use among adolescents to clarify the interrelation of smartphone dependence, lifestyle, dietary behavior, and mineral nutrition status. Methods: A total of 80 smartphone-addicted adolescents participated in this study and were divided into three groups (general, potential and danger group) according to smartphone dependence. The subjects' lifestyles and dietary behaviors were then surveyed, and hair mineral contents were analyzed. Results: Higher smartphone dependence was associated with lower average weekly sleeping time and later first smoking age. In the danger group, the rate of eating fast and the rate of snacking twice a day was also relatively high. Parents (45.0%) and mobile (30.0%) were the factors having the greatest influence on an individual's dietary behavior. In the hair mineral analysis, all subjects had lower selenium concentrations and higher lead concentrations than normal. In addition, the levels of aluminum in the danger group were higher than in the normal range and the highest among the three groups. Conclusions: It is necessary to guide adolescents to use smartphones correctly and manage dietary habits. In addition, careful attention is needed the mineral nutritional status of smartphone-addicted adolescents.

This study comparatively examines a causal model of employee attatchment which focuses on employee's organizational commitment and intent to stay with an organization. This study is based on two separate studies of employee attachment among teachers : the U.S. case of the Chicago Public Schools (CPS) and the South Korean case of the Seoul Educational District (SED). The main purpose of this study is to replicate in Korea the CPS study. A revised model based on the unique characteristics of Korean teachers is also developed and estimated. The Price Mueller model of employee attachment provides the basic theoretical framework for this study. It includes five general classes of variables : 1) employee responses to work variables : job satisfaction, commitment, and intent to stay; 2) psychological stress variables: role ambiguity, role conflict, work overload, and quality of students; 3) social structural variables: autonomy, routinization, distributive justice, and legitimacy; 4) economic structural variables: pay, job security, promotional opportunities, and job opportunities; and 5) work orientation variables : career commitment, normative commitment, work motivation, affectivity, work values, and met expectations. The data was collected through questionnaire survey and a sample of 649 secondary school teachers in Seoul, South Korea, was included in the final analysis. Covariance structure analysis (LISREL) was used to estimate the causal model. The results indicate that the endogenous variables of job satisfaction and commitment play a considerably less important role than in the U.S. model in mediating the effects of the exogenous variables on intent to stay, and the model fails to explain the majority of the variance in intent to stay. In addition, the new variables added to the revised Korean model do not bave significant effects on intent to stay. The structural characteristics of the employment relationship and labor markets associated with Korean teachers forced mobility and closed external markets - are largely accountable for the major differences between the Korean and the U.S. cases. The study suggests that conceptual and empirical work on what produces employee attachment under these structural constraints needs to receive more attention in future studies.

The purpose of this study was to identify the relationship between depression and physical health of the elderly and to provide fundamental data for programs which improve the health of this population. The subjects were 168 elderly people(55 years and older) who resided at home in Taegu. They were surveyed by interview using a closed- ended questionnaire. The survey was done from September 16 to October 16 in 2000. The instruments used in this study were general characteristics, Short form Geriatric Depression Scale(SGDS), Barthel Index, Muscular skeletal symptoms scale, Northern Illinois University's Health Self Rating Scale. The data were analyzed by using descriptive statistics, t-test, ANOVA, Pearson Correlation Coefficient, multiple regression with SPSS PC 10.0 version for Windows. The findings were as follows: 1. As compared 65-74 years elderly group, 75-84 years group was significantly higher score for depression(F=3.17, p=.026). As compared elderly group who has own spouse, the group who has no own spouse was significantly higher score for depression(t=- 2.44, p=.016). 2. The aged who have more limitation of Activities of Daily Living(ADL)(t=3.93, p=.000), pain of muscular skeletal symptoms(F=5.33, p=.002) and poor perceived health state(F=17.04, p=.000) showed the higher severity of depression than the aged who have not. 3. ADL correlated negatively with depression(r=- .293, p=.000), pain of muscular skeletal symptoms correlated positively(r=.251, p=.001), perceived health status correlated negatively(r=-.522, p=.000). 4. The combination of perceived health status and ADL explained 29.1% of the varience of depression. On the basis of the above findings the following recommendations are made; 1. Developing health programs is needed considering ADL, pain of muscular skeletal symptoms, perceived health status, demographic variables (age, spouse status) which have an significant effects on depression of the elderly. 2. In the following study, the use of the various scale is needed which reflects physical status of the elderly in home.

This study was to know the influence of familial environment and moral development on conduct disorder. Subjects were composed of 47 male and female patients with conduct disorder(patients group), 113 general male and female students(normal group), and 173 juvenile prisoners(JP group). The Korean Form of the Family Environment Scale(FES) was used to assess the family environment of the subjects and the Korean Defining Issues Test(DIT) was used to assess the moral development. Conduct disorder was diagnosed with the DSM-III-R criteria for conduct disorder. The influence of familial environment and moral development on conduct disorder was analyzed with ANOVA and the differences among groups were verified with Scheffe test. There was no difference in the socioeconomic status and the physical abuse by the parents among the three groups. But the rates of divorce or separation of the parents were significantly highest in the JP group and higher in the patients group than in the normal group. Especially the subjects of the JP group experienced the divorce or separation of their parents during the preschool or the elementary school periods. In regard to the family environment, there was no difference among the three groups in the Subscales of Expressiveness, Independence, Intellectual-cultural orientation, Moral-religious emphasis, Organization, and Control. ‘Cohesion Subscale’ was significantly higher in the normal group than in the JP group. ‘Conflict Subscale’ was significantly higher in the JP and patients groups than in the normal group. ‘Achievement orientation Subscale’ was significantly lower in the JP group than in the patients and normal groups. ‘Activerecreational orientation’ was significantly lower in the normal group than in the JP and patients groups. In gegard to the moral developmental stage, the lower moral developmental step was higher in the JP and patients groups than in the normal group. The higher steps were significantly higher in the normal group than in the JP group. There was no significant correlation between the degree of ‘Moral-religious emphasis Subscale’ and the moral development. The clinical implication and limitation of present study were listed and discussed.
