This study examined the correlation between college students' unemployment stress and affecting factors including physical symptoms, mental health, and self-esteem. In the results, students appeared to have more stress when they were female, in higher grades, in low satisfaction in their school life, in the lack of leisure time, in inadequate preparation for employment, and when they had none of those who could share their feeling on unemployment than students in the opposite situations. Students' physical and mental health had a positive relation with unemployment stress, and self esteem had a negative relation with unemployment stress. After multivariate analysis, the factors affecting unemployment stress were senior grade and depression. On the other hand, the factors predicting low umemployment stress were male sex, high level of self esteem, and satisfaction in preparation for employment. Therefore, the counselling program for employment preparation should include intervention strategies for enhancing self-esteem besides providing with information of employment.

The balance ability significantly decreased in the elderly because of deterioration of the neural musculature regulatory mechanisms. Several studies have investigated methods of improving balance ability using real-time systems, but it is limited by the expensive test equipment and specialized resources. Recently, Kinect system based on depth data has been applied to address these limitations. Little information about accuracy/inaccuracy of Kinect system is, however, available, particular in motion analysis for evaluation of effectiveness in rehabilitation training. Therefore, the aim of the current study was to evaluate accuracy/inaccuracy of Kinect system in specific rotational movement for balance rehabilitation training. Six healthy male adults with no musculoskeletal disorder were selected to participate in the experiment. Movements of the participants were induced by controlling the base plane of the balance training equipment in directions of AP (anterior-posterior), ML (medial-lateral), right and left diagonal direction. The dynamic motions of the subjects were measured using two Kinect depth sensor systems and a three-dimensional motion capture system with eight infrared cameras for comparative evaluation. The results of the error rate for hip and knee joint alteration of Kinect system comparison with infrared camera based motion capture system occurred smaller values in the ML direction (Hip joint: 10.9~57.3%, Knee joint: 26.0~74.8%). Therefore, the accuracy of Kinect system for measuring balance rehabilitation traning could improve by using adapted algorithm which is based on hip joint movement in medial-lateral direction.

Falling is one of the major public problems to the elderly, resulting in limitations of daily living activities. It can be induced by the functional loss of the balance ability and muscle strength in the elderly. It has been, however, not well investigated to suggest an effective methodology improving the balance ability and muscle strength for the prevention of the falling due to lack of information about the characteristics of the balance and muscle activations responded to the dynamic motions. The aim of the current study is, therefore, to identify the characteristics of the balance and muscle activations responded to the dynamic motions in Anterior-Posterior(AP) and Medial Lateral(ML) directions. For that, a motion capture system with eight infrared cameras, surface electromyogram system and Wii Fit system with a customized variable unstable base were used and kinematic and kinetic data obtained from the systems were analyzed for five healthy male($24.8{\pm}3.3years$, $177.4{\pm}2.0cm$, $73.9{\pm}12.9kg$, $23.5{\pm}4.0kg/m$). The results showed that the characteristics of the balance and muscle activations were differently responded to between the dynamic motions in Anterior-Posterior(AP) and Medial Lateral(ML) directions. These findings may indicate that customized dynamic motions should be applied to the training of the balance ability and muscle strength for the effective prevention of the falling. This study may be meaningful to providing basic information to establish a guideline improving effectively the balance ability and muscle strength.

The objective of our study was to evaluate the dietary intakes and eating habit for seniors utilizing ten different social welfare centers in Seoul, Korea. The total number of subjects of this study was 543(male: 199, female: 344) of 60 years of age or older. The survey was performed through personal interview questionnaires from May 3rd to June 1st 2006. After assigning subjects to four categories based on family type, single, couple, joint family, and other, these categories were compared with the estimated total nutrient intakes and eating habit. Validity was assessed by comparison with 24-hour dietary recalls and dietary variety score(DVS). The results showed that senior in single family type was far lower than that of couple family type in terms of frequency of meal per day and intake of snacks. Dietary variety score represented that a single female with social security beneficiary showed the lowest variety score compared with other family type. The lunch meal provided by social welfare center turned out to be the most nutritious diet and had significant proportion of daily intakes in essential nutrients such as protein, iron, vitamin A, and vitamin C. Taken together, the family type was a significant factor and the accompaniment is another effector on dietary pattern in the elderly. We strongly suggest that the current lunch program in welfare center should be expanded to breakfast meal, and furthermore the small commodity program is also needed to provide the elderly with meal for social communication.

Purpose: Bicycle riding is a healthy and cheap form of transportation and a popular form of recreation. This study aims to evaluate the epidemiology and the factors affecting the severity of bicycle-related injuries and to find effective methods for preventing injuries. Methods: This is a retrospective study of the patients'characteristics, the injury severity, the injury location, the effect of safety equipment on the bicycle injury based on information collected through the NEDIS (National Emergency Department Information System) from 1,284,429 patients who visited 55 emergency rooms nationwide. Results: During the research period throughout 55 emergency rooms 5,671 patients were seen because of bicycle injuries. The male-to-female ratio was 3.1:1, the median age 28 years old, and 42.6% of the patients were younger than 20 years old. Injury sites were mostly in the extremities(46.7%), the head(32.4%), and the face(14%), and 70.3% of severely injured patients had accompanying head trauma. Males aged 65 and older was possibly associated with severe head trauma. Of the patients who provided helmet information 4.8%(71patients) used helmets, and 95.2%(1392 patients) did not. In this group of patients providing helmet information, none of those wearing helmets died, but 0.4% of those not wearing helmets died. Conclusion: In this study, most bicycle injuries occurred in young adult men. From now, there seems to be a need for more effort on publicity activities on bicycle injuries and on the education of children and teenagers, who show a high incidence rate, and of senior citizens (over 65 years old) who show a high severity rate, about using a safety helmet to reduce the severity of injury.

Background : The purpose of this study is to verify the type of influence on the skin color according to the photoaging symptoms depending on the degree of external activities among the factors that influence the skin due to UV exposure and to obtain the basic study data on the physical therapy of the skin. Methods : In this study, in order to investigate the type of influence on the skin color according to the photoaging symptoms when the body is exposed to the UV rays having various effects on our body, a study was conducted using questionnaires and skin color measurement tool targeting 20 male college soccer students with many external activities and the senior high school students who has relatively less external activities due to the preparation for college entrance. The skin color was measured and the results were compared. Result : In the test group having relatively higher external activities, while they had less use of the sunscreen, they had more degree of UV exposure, and for the recognition of ultraviolet hazard, more were aware that it was harmful. In addition, in the skin color measurement test conducted targeting the son and the father in order to investigate the association between the skin color and the genetic factors, the experimental group showed a significant difference(p<.05) but the control group did not show any significant difference(p>.05). Conclusion : Based on such study results, the UV exposure time and the use of sunscreen are thought to be an important factor in the skin care.

This study evaluated methods of improving sustained learning participation by examining the structural relationship of school support consisting of professor support, friend-senior support and educational environment support, career decisionmaking self-efficacy, school satisfaction, and learning persistence depending on the characteristics of college students majoring in culinary art and food service. The study findings were as follows. First, the general characteristics of college students majoring in culinary art and food service were perceived significantly more by female students than by male students. Second, school support directly influenced the career decision-making self-efficacy and school satisfaction, but did not directly influence the learning persistence. Instead, school support influenced school satisfaction and learning persistence indirectly by the medium of career decision-making self-efficacy. Third, career decision-making self-efficacy directly influenced school satisfaction and learning persistence and indirectly influenced learning persistence by the medium of school satisfaction. Lastly, school satisfaction directly influenced the learning persistence, implying that school satisfaction is an important factor for the learning persistence of college students majoring in culinary art and food service. These results show that, because school members and environmental support cannot exclusively make learning persistence, diverse systems and programs must be developed and applied to improve the career decision-making self-efficacy and school satisfaction of college students majoring in culinary art and food service.

Purpose: This study was executed to investigate the route of the sexual knowledge acquisition and the sexual problem behavior of primary school students in a region. Method: The subjects of this research who were primary school 5, 6 grade students of 990 people were chosen at random in big cities, small towns and rural areas in Jeonbuk province. Result: The route of the sexual knowledge acquisition was through taking lesson & teacher in the school(40.6%), the peer group or senior member(26.1%), internet(15.3%), parents(10.0%), and multimedia(8.0%). The domain of the sexual problem behavior showed sexual impulse 3.8%, sexual violence 3.7%, masturbation 2.7%, voyeur 1.8%, prostitution 0.8%, transvestism 0.5%, exhibitionism 0.1%. The sexual problem behavior experienced by 5.0% or more of the subjects showed the experience of another person's compulsory touching on their body, the embrace desire and the kiss desire with opposite sexual friend. And the biggest sexual problem behavior of the subjects was sexual violence and sexual impulse to opposite sexual friend. The experience rate of the 6 grade was higher than that of the 5 grade (p<.05) and the male students' experience rate of another person's compulsory touching on their body showed higher than that of the female students(p<.05). Conclusion: The author through these findings suggests that systematic programs and curriculum should be developed for sexual problem behavior prevention.

This study analyzed qualitative data to examine the attitude toward the conditions of and the barriers to the work- family balance among unmarried workers. The data was drawn from 5 focus groups consisting of 4 workers each. The 20 participants, aged 21 through 38, were interviewed in mini groups composed of 2 male workers and 2 female workers each. The research depicts four main themes about their work-family balance: the image of a dual-earner family, women's market labor, housework, and the ideal conditions of a dual-earner family. This research concluded that unmarried workers desperately want to be part of a dual earning family for economic survival. However, they also know that it would be very difficult to make ends meet and to live as dual-earner families because of the lack of a proper social support system. However, most of them believe that they must solve these problems on their own, and they do not expect to receive help from systematic public policies. They think that they should find solutions by rearranging the role divisions between the husband and the wife or by asking for help from their parents or other relatives. The only assistance they expect from the government are reliable child care facilities and governmental incentives to promote stimulate the family-friendly workplace.
