Objectives: Police officers may be at a greater risk for cardiovascular disease (CVD) than the general population due to their highstress occupation. This study evaluated how an educational program based on the health belief model (HBM) may protect police officers from developing CVD. Methods: In this single-group experimental study, 58 police officers in Iran participated in a 5-week intervention based on HBM principles. Outcomes included changes in scores on an HBM scale, time spent on moderate to vigorous physical activity (International Physical Activity Questionnaire), body mass index (BMI), blood lipid profile, blood glucose, and blood pressure. The intervention consisted of 5 HBM-based educational sessions. Follow-up was conducted at 3 months post-intervention. The paired t-test was used to examine differences between baseline and follow-up scores. Results: All aspects of the HBM scale improved between baseline and follow-up (p<0.05), except the cues to action subscale. Self-efficacy and preventive behaviors improved the most. BMI decreased from 26.7±2.9 kg/㎡ at baseline to 25.8±2.4 kg/㎡ at follow-up. All components of the lipid profile, including triglycerides, cholesterol, high-density lipoprotein, and low-density lipoprotein, showed significant improvements post-intervention. Blood glucose and blood pressure also decreased, but not significantly. Nearly 25% of participants who were not physically active at baseline increased their physical activity above or beyond the healthy threshold. Conclusions: A relatively brief educational intervention based on HBM principles led to a significant improvement in CVD risk factors among police officers. Further research is needed to corroborate the effectiveness of this intervention.

A great deal of attention has been paid to the quality of life in citizens due to the increased number of long term life expectancy. reported as effective in the health promotion of the senior citizens. In this study, the principal investigator developed an exercise program for the senior citizens, which could be educated and managed by nursing staff. This kind approach may support the need of exercise program on regular base via the social organization, which may mean the intentional change of life style. The exercise program consisted of exercise, health education, and a direct the population of the senior A regularexercise has been nursing care. A quasi -experimental study was conducted to investigate the effects of excercise program on health of the elderly in senior citizen's center. Independent variable was a 9 weeks exercise program. Dependent variables were: 1) physical health [e.g. physical fitness(cardiopulmonary endurance, back muscle strength, grip strength, muscular tolerance, flexibility and body fat proportion), physiologic parameters(blood pressure, pulse, respiration. and blood glucose), and perceived physical health status; 2) mental health measured by depression score; and 3) cognitive perception of exercise measured by usefulness and self-efficacy. A total of 37 subjects was randomly assigned into either the control group (without the exercise program: n=18) or the intervention group(with the exercise program: n=19). The results of the study analyzed using a SAS, were as follows: 1) In physical fitness of physical health, there was a significant improvement in cardiopulmonary tolerance. back muscle strength. muscular tolerance and flexibility in the intervention group, compared to the control group, while no difference in grip strength and body fat proportion. The exercise program resulted in decreases in blood pressure, pulse, respiration and blood glucose within normal range and improvement of perceived physical health status in the intervention group. 2) There was a slight increase of mental health(depression score) in the intervention group compared to the control group. but without statistical significance. 3) There was a significant improvement in cognitive perception of exercise(e.g. usefulness and self -efficacy) in the intervention group, compared to the control group. It was concluded that the exercise program employed in this study was appropriate for women senior citizens and had a positive effect on health in general.

Public expenditures on long-term care are a matter of concern for Korea as in many other countries. The expenditure is expected to accelerate and to put pressure on public budgets, adding to that arising from insufficient retirement schemes and other forms of social spending. This study tried to foresee how much health care spending could increase in the future considering demographic and non-demographic factors as the drivers of expenditure. Previous projections of future long-term expenditure were mainly based on a given relation between spending and age structure. However, although demographic factors will surely put upward pressure on long-term care costs, other non-demographic factors, such as labor cost increase and availability of informal care, should be taken into account as well. Also, the possibility of dynamic link between health status and longevity gains needs to be considered. The model in this study is cell-base and consists of three main parts. The first part estimated the numbers of elderly people with different levels of health status by age group, gender, household type. The second part estimated the levels of long-term care services required, by attaching a probability of receiving long-term care services to each cell using from the sample from current year. The third part of the model estimated long-term care expenditure, along the demographic and non-demographic factors' change in various scenarios. Public spending on long-term care could rise from the current level of 0.2~0.3% of GDP to around 0.44~2.30% by 2040.

In this study, a new reaction system is proposed to solve the problems of the existing 2,3-Butanediol (2,3-BDO) dehydration reaction system. It was confirmed that the reaction system did not wok as it should operate properly when using a furnace, which is commonly used in commercial processes, to raise the reactant, 2,3-BDO, to the reaction temperature, 360 ℃, at near atmoshperic pressure. It is because of the substance considered to be oligomers of 2,3-BDO. It can lead to safety problems, such as blockages inside the furnace's tube and explosions, as well as tricky maintenance issues in the reaction system. To solve it, the temperature of reactant can be brought down by using a heat exchanger with High Pressure (HP) steam instead of the furnace, which has a hot spot problem through the vacuum operation and reduce the reaction temperature. It can be seen that the reactor performance is almost similar under the vacuum operation and the lower reaction temperature, 330 ℃, by using a reaction kinetics. This result explains why the new reaction system is proposed.

There is a growing interest in breast augmentation surgery, which can most effectively maximize femininity, among modern women around the world. However, breast augmentation surgery is considered one of the most terrifying surgeries many women are afraid of, as many cases of its side effects have been reported. As a way to provide a complementary method to deal with it, this study investigated the effects of a non-surgical breast enhancement program by stretching soft tissue of the breast. According to the results, there was no change in body weight and breast elasticity, but there were marked increases in breast cup size, breast diameter and volume of the women who used this program. The external soft tissue expansion system was found to be effective in Korean women's change of breast shape. On the other hand, users should use this system regularly for some period of time, and this would limit their social activities. Therefore, for the effective use of this system, its users should make individual efforts.

Purpose: The purpose of this study was two folds: first, to identify the level of self care behavior of the hemodialysis patients and second, to find the correlation between the self care behavior and the physiologic indices. Method: The subjects were 52 hemodialysis patients, male and female, who have regularly received hemodialysis dialysis at the Dialysis Room in a leading teaching hospital, Seoul. The patients responded to the self care behavior questionnaires including their socio-demographic characteristics. The respondents have regularly recorded the self care log book. The physiologic indices, clinical characteristics related to the disease and hemodialysis were collected by the chart review. Result: The mean score of the self care behavior was 3.46. The mean score of the self care behavior on categories demonstrated as follows: medication 4.29, fistula management 4.13, management of physical problem 3.71, diet 3.28, exercise and rest 3.22, blood pressure and body weight management 2.97 and social adjustment 2.05 in order. Thirty patients managed discomfort of their fistula. Eleven patients took exercise for 0.5-1 hr/week. Thirty patients measured their body weight daily and thirty two measured their blood pressure daily. The score of self care behavior was significantly correlated with the mean weight gains between the dialysis sessions(r=-.312, p=.05). The mean weight gains between dialysis sessions was found to be high as the level of serum phosphorus and potassium increased(r=-.316, p=.05, r=-.465, p=.01). Conclusion: The result suggests that nursing intervention to the hemodialysis patients to improve self care behavior should be encouraged and further developed.

Objectives: This study attempted to apply the Intervention mapping and Transtheoretical models to develop a program to promote moderate alcohol drinking in university students. Methods: Surveyed data from 1,137 university students were analyzed to identify personal and environmental determinants for alcohol drinking. Based on these determinants, program objectives were established. Crossing the objectives with related important determinants resulted in matrices of learning objectives for which educational strategies were developed. Subsequently, an intervention program were designed to achieve those objectives. Results: Identified personal determinants included awareness, attitudes, self-efficacy and behavioral skills. Environmental determinants were binge drinking behaviors of family members and peers, and social pressure for drinking. Program, impact and learning objectives were developed to change the identified determinants. Program activities included provision of information on positive and negative consequences of binge drinking, opportunities for assessing one's drinking pattern, increasing outcome expectancies of and skill building for monitoring drinking, resisting peer pressure and managing stress. To facilitate adoption and maintenance of the program, an intervention diffusion plan was suggested. An evaluation plan was developed by utilizing RE-AIM framework. Conclusions: In order to expand evidence bases for effective theory-based programs, the developed program should be tested in diverse university settings.

The purpose of this study is to develop and evaluate the health promotion program to increase the functional status of the in-house stroke patients. The subjects for the experiment are 38 in-house stroke patients in a health center and welfare centers suffering from hemiplegia. The experimental group consists of 19 stroke patients and the control group consists of another 19 stroke patients. The program was applied to the experimental group for 8 weeks. The subjects were given health education at the first week. At the second and the fifth week they were given counselling on health by home visit. At the third, the fourth, the sixth and the seventh week they were interviewed by phone about health, and at the last week they shared their experiences through group meeting. The results of the study are as follows: 1. The degree of ADL in the experimental group increased significantly, compared with that of the control group. 2. In the experimental group the degree of Range of Motion in shoulder abduction, elbow flexion, hip flexion and ankle dorsiflexion increased significantly, compared with that of the control group. 3. In the experimental group the degree of muscle strength in elbow flexion, knee extension, and ankle dorsiflexion increased significantly, compared with that of the control group. 4. Systolic pressure, diastolic pressure in the experimental group decreased significantly, compared with that the control group. 5. HWR in the experimental group didn't decreased significantly, compared with that the control group. 6. The degree of depression in the experimental group decreased significantly, compared with that the control group. 7. The degree of social adaptation in the experimental group increased significantly, compared with that the control group. The results above show that the health promotion program for this study was effective in promoting the performance of lifestyle for health improvement of the in-house stroke patients. Therefore, it is considered that the program can be used as an efficient nursing intervention for the in-house stroke patients who need continuous health-improving behaviors.
