This study evaluated the thermal physiological and psychological responses elicited when wearing cold protective jackets with aerogel fillings in two cold environments, one without air velocities and one with air velocities (2.3 m·s-1), at an air temperature of 10℃. The participants were five healthy young males. Measures were taken of physiological parameters, blood pressure (BP), heart rate (HR), core temperature, oxygen uptake (Vo2), and microclimate (temperature and humidity). The psychological parameters evaluated were thermal and wetness sensation. No differences were observed in systolic blood pressure, heart rate, and oxygen intake between the conditions. At tympanic temperature, a significant difference was observed between the conditions during exercise (p<.05); . A significant difference was observed in the microclimate temperature of the clothing according to the airflow, and temperature changes in the chest and back revealed different patterns. Significant differences were observed in thermal sensation (whole body (p<.05), chest (p<.05), back (p<.01)) between airflow conditions. The results therefore indicate that cold protective jackets with an aerogel filling are suitable for people operating in low-temperature and airflow environments.

Objectives: This study examined to explain the practical health behaviour and health-related quality of life, and their influencing factors in high school students. Methods: Total of 718 high school students from 1 school in Seoul were assessed with a self-administered questionnaire regarding general characteristics, health related characteristics, obesity index(Height and weight calculated by using the relative weight law: obesity group>20%, overweight group $10{\sim}20%$, normal weight group $-10{\sim}10%$, under weight group <-10%), health behaviour in school-aged children(eating, exercise and weight control) and health-related quality of life(PedsQLTM4.0 Generic Core Scale: physical health, emotional functioning, social functioning, school functioning). Results: Major results were as follows. 1. The rate of obesity by obesity index was 5.3% of high school students. Obesity incidence in adolescents was mainly associated with gender and parents whether obesity. 2. Perceived health status was lower in obese adolescents than in normal adolescents. 3. The rate of miss a breakfast was 37.9%, and obesity group than normal weight group were fruits, vegetables and milk intake at least, a lot of fastfood intake. During the past week, followed by intense physical activity, and overweight consumed a lot of time for TV and the Internet. Overall, under weight group and normal weight group belong to the students evaluated fatter than themselves. Weight control for weight loss, gain and maintain was grater in obesity group than in normal weight group. Weight loss showed highest scores in overweight group which appeared significant difference. 4. Obese adolescents compared with other groups, reported lower total QOL score and all QOL in domain, and especially social functioning showed significant differences. 5. Factors influencing the adolescents's QOL were found to be gender, perceived health status and exercise. Conclusions: High school girls were aware of their bad health status and likely to improve the QOL by practicing health behaviour. But obese adolescents were likely to degrade the quality of life by reducing the practice of health behaviors. So further school-based education about proper practical health behaviors and obesity prevention is necessary.

The aim of the study was to explore the current status as well as personal views, attitudes, and beliefs regarding daily meal consumption (DM) and food supplement use (FS) in conjunction with the improvement of health condition of the women. Eight focus group interviews were performed and the interview material was condensed systematically with the aim to extract core meanings related to DM, FS, and menopause-associated health. Participants were 40 in number and showed ages ranging from 45 and 60 years with various menopausal status. Current status and beliefs about DM, resources of purchase motivation of FS, types of FS that are currently used, and perceived effects and personal beliefs about FS are discussed. Theme content analysis revealed 3 themes for beliefs about DM, 5 themes for beliefs pertaining FS, and 4 themes for the association between DM and FS. Non-dietary factors such as positive mental attitude and exercise appeared to be also important to maintain good health. The bottom line message from this study may be that proper nutrition through daily meals is essential for good health, while food supplement are used merely to supplement the diet. Findings from this study may deepen our understanding of how women who translate their lifespan through "menopause" perceive the roles and meaning of DM and FS, suggesting health professionals need to monitor and evaluate DM and implement strategies targeting the improvement of daily meal quality of middle and older aged women.

PURPOSE: This study was conducted to investigate the intervention effect obtained by applying an ICF tool to improve the dressing in a patient with rotator cuff syndrome to schematize the problems and approaching with PNF to solve the problems. METHODS: The subject of this study was a 44-year-old patient who underwent surgery after complete right rotator cuff tear. To treat his symptoms, the processes of clinical practice were implemented in the order of examination, assessment, diagnosis, prognosis, intervention, and outcome. During examination, patient information was collected using the ICF core set. In the assessment, the problems were schematized, and an ICF assessment sheet was used to identify the interaction of the problems. The diagnosis was made by clearly describing the causal relationship derived from the assessment in ICF terms. To solve the problems, the intervention was given in the order of indirect, direct, and task based on the philosophy of PNF. To evaluate the outcome, the differences before and after the intervention were compared. Additionally, the comparison for the ICF qualifier is presented with the ICF evaluation display. RESULTS: The results of the study showed clinical advantages in shoulder strength, eccentric control, range of motion, scapular stability, and shoulder pain. Overall, our patient with rotator cuff syndrome showed improvement in dressing and undressing activity in response to the PNF strategy. CONCLUSION: Application of the PNF intervention strategy after complete rotator cuff tear would have a positive effect on patient upper extremity function.

Government Research Institutes(GRI), together with universities and private research labs, constitute the core of the Korea's national innovation system, The aim of this paper is to analyze the current system of GRIs and the National Research Councils(RC) in Korea, and suggest some policy recommendations conducive to achieving a world class competitive research system. To identify the problems and policy issues, we have conducted interviews (with executives staffs of RCs, GRIs and government ministries) and questionnaire surveys. For benchmarking purposes, we have visited 9 public research institutes in the USA, UK, Germany, and France. From the analysis of the problems revealed from the interviews and questionnaires, 6 policy variables are identified: three of them, which we call systemware variables, are governance structure, resources allocation system, and management control system; and the other three, which we call humanware variables, are visions and strategic goals, leadership, and research manpower, respectively. We have found that 1;he current GRI/RC systems are inefficient mainly due to the rigid and bureaucratic governance structure and inconsistent resource (i.e., government budgets) allocation systems. We reject the idea of replacing the current RC system with such radical alternatives as 're-governmentization'or 'privatization'. Instead we recommend that the government introduce a better system of governance and national budget allocations, which in turn would help induce a better management control systems, clear research visions and goals, strong leadership on the part of the RC chairman, and more creative and motivated researchers. These recommendations may provide opportunities and rooms for chairmen of RCs and presidents of GRIs to exercise more positive leadership in terms of fitting the visions and goal of GRIs to the national R&D strategy and creating a rational management control system as well as motivating researchers in GRIs to be more creative and productive.

The aim of this study is to find ways to apply the strategic communications to the Republic of Korea Navy. It may be a little bit late for the ROK Navy to accommodate the SC in these days because the adoption and implementation of the SC by the Combined Forces Command has already been begun. It was in 2007 when the SC was in place in the CFC. ROK's Ministry of National Defense and Joint Chiefs of Staff have also mulled over the SC and begun to apply it in part in the annual exercises such as Key Resolve command post drills and Foal Eagle field training exercise, etc. For the ROK Navy, in addition to those exercises, it is faced with further areas like North Korean maritime provocations and other maritime incidents where its version of SC is needed. As noted, the SC is not intended to deter or defend directly those provocations and incidents, but aims to create conditions favorable to the achievement of the navy's strategic objectives. The ROK Navy has to establish a SC planning center and implementing organizations within the Headquarters to be consistent with its above organizations such as MND, JCS, and CFC that have already applied the SC in part or in entirety. SC center and other related organizations need to be under the control of VCNO and the center needs to be located and administered by the policy division in N-5 at the HQs. The vision of the navy's SC is the winning without combats and the least damages in time of war. In other for the navy to reach the vision, the strategies to be executed are early establishment of SC implementing organizations, forming consensus over the need for the SC within the navy, strengthening core competencies to apply the SC, acquiring the SC experts and making doctrines on the SC. The SC, in addition, in the navy has to be planned and implemented in not only peace time and crisis time but also war time.
