Objectives: This study was obtained to identify current education status of the community dental hygiene practice. Methods: It was designed cross section and self-reported on-line questionnaire(Survey monkey). It was performed probability sampling by targeting 82 dental hygiene schools(each one faculty member) in charge of community dental hygiene curriculum and 254 community health centers's community dental hygienists whom was working at oral health section. The response rate was 60% and 53%, respectively. The questionnaire consisted of time, duration, practice group, evaluation method, and practice contents including 63 learning objectives of dental hygiene. Results: Nearly half of these schools conduct such community field work practice in the spring semester of the junior year. This practice was mainly progressed based on average 4 students as one team per each one school for 7-8 hours a day during the period of more than 5 weeks(p<0.05). However, in case of both school and community health center, almost half of feedback after practice was not achieved and there was a difference in needs for practice education between schools and community health center. Conclusions: We should be considered that a sufficient consultation for the practice environment and its contents between schools and community health centers. It was considered that development of a standardized practice manual reflecting such requirement.

Nursing role tends to be more complex then before because of the increased number of health professionals and of the health needs of patient. Accordingly, nursing role expectations are various and sometimes conflict by its role set. There are various literatures on role conflict of nurses and discussed how to eliminate the conflict in order to improve nursing service particularly in the hospital organization. This study was designed to determine if role conflict exist among nurses who work in a hospital and if so what resolution were most frequently selected by the nurses to the role conflict. The study population was fifty six registered nurses of K university hospital. The fifty six was defined and selected by nonproportional stratified sampling method to obtain subjects who are from uniform role set. A questionnaire, a list of role connect, stimulated by the literature review, knowledge based on several years' experience in nursing was formulated by the author and administered to the study population. The questionnaire included twenty nine closed question items of role conflict and classified according to the intra sender conflict, intersender conflict, person conflict and interperson conflict. The response choices to the questions range on a scale continuum with degrees of conflict from one to five: never - 0, seldom - 1, occasionally - 2, frequently - 3, and mostly -4. Per cent, means, standard deviation, and x² -test were used to analyze data. The findings of the study could be summarized as follows. 1. General characterstics of the study population: Most of the population were between the age of 22-27 and are not married. 2. Analysis of Role conflict Existence of Role conflict of nurses was found by the total mean conflict score, 2.06. Inter Sender Role conflict revealed the most high mean conflict score and the lowest one was inter person role conflict. Among the five role senders of nurses: Physician, patient and hi9 family, peer and superior, nursing students and hospital administrator, nurses showed the highest conflict mean score for physicians and the lowest score for Nursing student. 3. Analysis of role conflict resolution. Compromise through discussion with the role sender was the most frequently selected method by the respondents. The result also showed that the respondents tend to resolve the conflicting situation created by patient or his family by persuation. On the o thor hand, Avoidance and ignorance was frequently chosen for the conflicting role expectations from the hospital administrator.

With the increase of double-income families, parents are not free in terms of time and space in communicating with teachers. Also for teachers, with many students and heavy load of work, communication with parents has been poor. As a means for overcoming this kind of situation, this research examined the current status of communication between teachers and parents using SMS and problems to solve. The investigation of the actual conditions of SMS use showed that there was a high number of answers pointing out that SMS is needed for the exchange of information regarding children and educational activities, and teachers pointed out that the communication was effective for exchanging educational information regarding children whereas parents pointed out that it was effective in improving the children's attitudes. Based on the results of the analysis, the following was found as tasks to be solved: preparing a plan for revitalizing SMS use, solving the burden that parents have in communicating with teachers, becoming more friendly with teachers, investigation of the reason why there is no response regarding SMS and preparing countermeasures, providing information appropriate to what parents want, increasing the reply rate of parents, expansion of text capacity, and trouble with getting online with a computer.

Purpose: This study provides information for the development of educational programs for improving awareness of support to the elderly among adolescents. Methods: The 350 students of high schools located in Seoul were selected as subjects and surveyed using structured questionnaires during 11th~15th of April in 2014. The 327 subjects were used for analysis and the response rate was 93.4%. SPSS/WIN18.0 program was performed for t-test, ANOVA and regression analysis. Results: First, adolescents with parents aged over 50 compared to those with parents younger than 40 showed high level of awareness of support to the elderly. The high level of cognitive factors including image and perception towards the elderly (t=3.07, p=.01) were significant factors of awareness of support to the elderly. In experiential factors, adolescents with extensive influence of media and experiences with cohabitation with grandparents, and experiences with voluntary service activities were statistically significant with the high level of awareness of support to the elderly. Second, in regression analysis, adolescents' economic support awareness was higher with the stronger influence in the elderly-related media (${\beta}=.221$, p=.032). The emotional support awareness was higher among the eldest sons (${\beta}=.220$, p=.017) and perception (${\beta}=.352$, p=.001) to elderly (${\beta}=.221$, p=.032). Physical support awareness was higher when the positive image for the elderly (${\beta}=.223$, p=.016) and the high perception towards the elderly (${\beta}=.293$, p=.007). Conclusion: The awareness of support to the elderly should be constantly strengthened to the adolescents. Despite the rapid increase of the elderly, studies are not sufficient. Further research will be necessary.

The purpose of this study was to identify the relationship between the index of Electrocardiography(LF/HF) and the occurrence of drowsiness driving while driving in a simulated situation. Participants were 31 undergraduate students with an experience in driving and they participated 30 minutes driving under enough sleep condition and 1 hour under the sleep deprivation condition. The Euro Truck Simulator II was used for driving simulation task and ECG and perceived drowsiness of each participants were measured during two driving conditions. Perceived sleepiness recorded by the checklist every 10 minutes and ECG data extracted before and after 15 seconds of every 10 minutes to verify the relationship between two variables. The results showed that the level of perceived sleepiness under sleep deprivation condition was higher than that under the enough sleep condition, and the level of LF/HF under sleep deprivation condition was lower than that under the enough sleep condition. In addition, the result of analysis of repeated measure ANOVA for ECG indicated that authentic sleepiness revealed in 20 minutes after the start of driving under the sleep deprivation condition. However, the result of perceived drowsiness indicated that authentic sleepiness revealed in 30 minutes after the start of driving. These result suggest that the time difference between biological and perceived response on drowsiness may be exist. Finally, the significant negative correlation between the LF/HF level and perceived drowsiness was observed. These findings suggest that ECG(LF/HF) can be an possible index to measure drowsiness driving.

The purpose of this study is to investigate the effect of color, shirt tone, tie tone, perceiver's gender on impression formation by applying tone on tone coloration of shirt and necktie: coloration of two colors. The experimental materials developed for this study were a set of stimulus and response scales. The stimuli were 32 upper body photographs which were color outputs by CAD system(4D-box program). We unified those colors of shirts and neckties same, then made shirt and necktie tone differently. 27 bi-polar adjectives, each of which was graded into seven in its degree, were used to evaluate the impression. The subjects of this research were 192 male and 192 female college students in Gyeongnam province including Jinju City. The data was analyzed by using SPSS program. Analysis methods were four-way ANOVA. The items of the adjectives were classified into 5 impression dimension. - potency, activity, attractiveness, visibility and tenderness. Color, shirt tone, tie tone, and perceiver gender influenced on 5 impression formation by interaction as well as independently. Blue tie with vivid, light or dull tone had an effect on the formation of potency impression, vivid or light tone of shirt affected activity regardless of color or tie tone. As shirt and tie had different tone, effect on the formation of attractiveness impression, light tone had a negative effect on visibility but positive effect on tenderness. red color were more effective than blue expressed on visibility and tenderness in shirt or tie.

The purpose of this study is to evaluate the roles of expected self-control and expected self-control results in explaining adolescents' Internet addiction. In the study model, expectations of self-control and self-control results directly determine Internet addiction and Internet use time meditates the impacts of expectations of self-control and self-control results on Internet addiction. The study subjects are 1,080 middle and high school students in Busan. Stratified cluster sampling is applied by school type and school year. The response rate is 96%(l,037cases). This study develops the scales of expected self-control and expected self-control results. The scales of Internet addiction are devised by using the concept of functional dependency such as salience, withdrawal symptoms, mood modification, tolerance, relapse, and conflict. For verifying the study model, path analysis and multiple regression models are applied for identifying path significants and evaluating confounding effects of control variables, respectively. Moreover, multi partial F-test is performed for selecting the best regression model. Expected self-control is a significant determinant of Internet addiction and Internet use time that also significantly explains Internet addiction. The total effect of expected self-control towards Internet addiction is -.95. The total effect is comprised with the direct effect (-.71) and the indirect effect(-.24). In this result, the direct effect refers a curative effect since expected self-control directly reduces the level of Internet addiction, and the indirect effect refers a preventive effect because self-control can reduce time of Internet use that is a direct determinant of Internet addiction. In the test of the confounding effects of control variables, there are no confounding effects in the models of multiple regression. It implies a robustness of the study model as regards control variables. In conclusion, improving adolescents' expected self-control can control Internet addiction level. This finding implies that a health promotion program for improving expected self-control can be a cost effective method compared to other approaches.

This study aims to help improving the quality of military food service as identifying awareness, attitudes and satisfaction of cooking soldier on their duties and providing basic data to find out alternatives on the basis of identified data. The analysis results are described as follows. For general demographics of subjects, sergeants consisted of the highest percentage of population as 38.8% in terms of the rank. For educational background, the percentage of graduates or college students was 82.5%. For the characteristics of job performance of cooking soldier, those who studied entirely different courses from cookery and became to work as cooking soldier were 92(89.3%) of total subjects. For the question why they became to work as cooking soldier, the response that they didn't know the reason showed the highest percentage as 63.1%. Those who selected cooking soldier because they were interested in cookery were only 25.2%. And 94.2% of the population had no certificates related to cookery. With respect to awareness on training period to carry on duties as cooking soldier, 3 months were selected as the most appropriate period as 36.9%. In accordance with research on job percentage of cooking soldier, 'cleaning and washing' consisted of the highest percentage among ordinary duties as 16.8%, followed by 'cooking' as 12.3% and 'food dispensing' as 11.8%. This study suggests as follows on the basis of the results of this researches. Cooking soldier requires expertise, but the privates with short period of service are discharged from military service when they are accustomed to their duties and become experts. Accordingly, the cooking soldier system could not achieve more than its ordinary performance. Therefore, it is required to post non-commissioned officers who can serve for a long time as the special resources.

The relationship between copper content in scalp hair and mental retardation was investigated. Samples of scalp hair were collected from 297 mentally retarded children who were students in one of two schools providing special educational services, one, consisted of children living in an orphan home, the other, children living with parents. For comparison, 117 scalp hair samples were collected from the children who had got average or above average academic achivement in a regular elementary school. Hair samples were taken from the nape of the neck and the copper content was determined by an atomic absorption spectrophotometer (IL 551). There was no statistically significant difference in scalp copper levels across different age groups except female orphan group, but no trend or correlation between copper conents and age was found. The hair copper contents of the mentally retarded children groups were significantly lower than that of control groups. But there was no dose-response relationship between degree of mental retardation and hair copper level. The hair copper contents of the group accompanied by Down's syndrome and unknown group were significantly lower than that of control group in both sex, and in the case of accompanied by epilepsy or autism, lower than control group in male. Although the results of this study show no evidence that mental retardation has owed to copper deficiency, the possibility of copper deficiciency in their fetal or infant age could not be ruled out. Thus further study is needed to determine whether mental retardation could be attributed to copper deficiency, through the examinations about their living environments, dietary pattern, eating habit and the impact of copper deficiency on brain development.
