The objective of this study was to investigate the relationship among the variables and effects of depression and physical activity on fatigue in the elderly with chronic disease. A descriptive research design was employed in this study. In total, 500 elderly patients diagnosed with chronic disease were selected from 3 medical centers for the study. The measurements were used to examine their general characteristics, fatigue, depression, and physical activity. To analyze the data, statistical analyses, including ANOVA, t-test, Scheffe's test, Pearson's correlation coefficient, and hierarchical regression analysis, were conducted for the analysis of the data. The results indicated that the age, gender, and educational level in the first step model explained 6% of the effect on fatigue among the elderly with chronic disease. In addition, depression and physical activity in the second step model explained 16% of the effect on fatigue. These findings demonstrate the significance of (considering) depression and physical activity related to care plans when developing health-programs for decreasing fatigue and planning intervention strategies.

The purpose of this study was to investigate the weight control behaviors, the degree of fatness and dance major on behalf of finding the effects of eating disorders. 779 female high school students, 283 dance major students and 496 general major students, were participated in the study. A self-reporting type of questionnaire survey was conducted during the period from $6^{th}$ May to $18^{th}$ April of 2005. Collected data were processed using SPSSW in 12.0; they were analysed through frequencies, percentages, means and standard deviation, and stepwise multiple regression analysis. The results of this study are as follows : 1. With regard to the level of eating disorders(EAT-26), 33.9% of risk group of eating disorder female dance students, and 13.7% of risk group of eating disorder female general major students. Weight-control behaviors in this research were 1) weight control concerns, 2) weight control trial, 3) weight control methods (prescription of M.D., ways of weight control), 4) eating habits. First, 56.6% of subjects had high concerns about weight control, and 92% of subjects had tried weight control. Second, only 5.1% of subjects were prescribed by M.D. Third, subjects had been using wrong methods(25.7%) of weigh control such as fasting, using drugs, vomiting, wearing laps etc. Fourth, 42.7% of the subjects had bad eating habits. The degree of fatness was as follows: 1) BMI(Body Mass Index), 2) self report about weight 3) distorted body image. Depending upon the BMI, the subjects with obesity were not found in female dance students; Comparatively, 36.9% of dance students were fat and 1.4% of the students were very fat. In terms of distorted body image, only 14.9% of all subjects were the same between the subjective degree of fatness and the objective degree of fatness. 2. As a result of multiple regression, six variables were found significant($R^2=11.6%$, P < 0.01). Concerns about the weight control significantly influenced on eating disorders(EAT-26). At the same time, major(dance), wrong methods of weight control, distorted body image, prescription of M.D, and eating habits had significantly influenced on eating disorders. This results indicates that the risk of eating disorders among female dancer students was very high. Therefore, professional intervention is needed for female dance students to prevent the eating disorders.

There can be little dissension that the ultimate goal of all physical therapy interventions with the elderly is to restore or maintain the highest level of function possible for the individual. Whenever physical therapists take on this challenge, they assist elders in maintaining their identities as competent adults. Advancing age is associated with profound changes in body composition, including increased fat mass, decreased fat-free mass(particularly muscle), decreased total body water and decreased bone density. Along with these changes in body compositions, and perhaps as a direct result of them, elderly people have lower energy needs, reduced strength and functional capacity and a greatly increased risk for such diseases as noninsulin-dependent diabetes mellitus and osteoporosis. Resistance training is considered a promising intervention for reversing the loss of muscle function and the deterioration of muscle structure that is associated with advanced age. This reversal is thought to result in improvements in functional abilities and health status in the elderly by increasing muscle mass, strength and power and by increasing bone mineral density. In the past couple of decades, many studies have examined the effects of Resistance training on risk factors for age-related diseases or disabilities. We have explored the positive and negative aspects of older adults' participation in resistance training programs. The benefits to older adults are reported to be increased strength, endurance, muscle capacity, and flexibility; more energy; and improved self-image and confidence. The negative aspects include some pain or stiffness and other nonspecific problems. The positive and negative aspects of resistance training are therefore very similar to those in younger populations. Scientific investigations over the past 10 years have demonstrated that resistance training can be safely and successfully implemented in older populations. Even the frail and very sick elderly can benefit and improve their quality of life. Proper design and progression of a resistance training program for older adults is vital to optimal benefits from resistance exercise. The results of data provided by this research on resistance training for health shows that there is enough existing evidence to conclude that resistance training, particularly when incorporated into a comprehensive fitness program, can offer substantial health benefits which can be obtained by persons of all ages. These benefits, including improvements in functional capacity, translate into an improved quality of life.

In Korea, 28,641 cases of traffic accidents were caused by drunk driving in 2010. These statistics accounted for 12.62% of total number of traffic accidents. Moreover, the percentages of deaths and injuries from them were nearly 15% of those from whole traffic accidents. While police has emphasized enforcement efforts in order to reduce drunk driving, culture generous to drunk driving in addition to the absence of an appropriate intervention system for habitual drunk drivers have contributed to the increasing number of the drunk driving accidents in Korea. This study examined specific behavioral changes in drunk driving by comparing drivers' behavior pattern in non-alcoholic condition to those in alcoholic condition, using a psychomotor test and a driving simulator. In the psychomotor test measuring participants' reactions to the target stimulus, it was revealed that participants' correct responses were decreased, false responses were increased, and no responses also were increased after drinking. Furthermore, in the driving simulator performance after drinking, not only driving speed was faster but also the deviation of an accelerator pedal pressure and of the vehicle's lateral position were much increased. These results indicated that alcohol consumption would impair visio-cognitive ability and deteriorate driving safety. Finally, the implications and limitations of our findings and suggestions for the future research were discussed.

This study aimed to investigate whether mass drug administration (MDA) intervention has an equivalent effect on reducing the prevalence and intensity of Schistosoma haematobium infection regardless of the baseline values. A repeated cross-sectional survey was performed targeting students of 12 primary schools in Al Jabalain and El Salam districts of White Nile State, Sudan, at both 1 week before and 8 months after the MDA. Prior to the baseline survey, schoolaged children in Al Jabalain had received MDA interventions twice in 4 years, while those in El Salam had not. The baseline prevalence was 9.1% in Al Jabalain and 35.2% in El Salam, which were reduced to 1.8% and 5.5% at 8 months after the MDA, respectively. The corresponding reduction rates were 80.3% and 84.4%, not significant difference between both districts. However, changes in the geometric mean intensity (GMI) of egg counts were significantly different between both districts. The baseline GMIs were 14.5 eggs per 10 ml of urine (EP10) in Al Jabalain and 18.5 EP10 in El Salam, which were reduced to 7.1 and 11.2 EP10 after treatment, respectively. The corresponding reduction rates were 51.0% and 39.5%. In conclusion, MDA interventions were found to bring about similar relative reduction in prevalence regardless of the baseline value; however, the relative reduction in infection intensity was more salient in the district with a low baseline value for both prevalence and intensity. This clearly points to the importance of repeated MDA interventions in endemic areas, which will eventually contribute to schistosomiasis elimination.

(-)-Epigallocatechin-3-gallate (EGCG), a green tea polyphenol, has been shown to have strong antibacterial, antiviral, antioxidant, anti-inflammatory, and chemopreventive effects. However it is unknown whether EGCG can recover alcohol-associated pancreatitis. The aim of this study was to investigate the effects of EGCG on pancreatic enzyme activities and the expressions of pancreatic regenerating related markers, such as adenosine monophosphate-activated protein kinase (AMPK), raf-1 kinase inhibitor protein (RKIP), and Regenerating gene 1 (Reg1), in mice pancreatic primary acinar cells. Our results revealed that activities of ${\alpha}$-amylase and chymotrypsin were significantly increased in the cells treated with ethanol compared to the untreated control cells; however, the increased activities of both enzymes were markedly reduced by pretreatment with EGCG. Phosphorylation of AMPK and total expression of RKIP were decreased in the ethanol-treated primary acinar cells; however, these were both significantly increased in the EGCG-pretreated cells. In addition, when EGCG was treated, expression of Reg1 was markedly increased compared with that of the control or the ethanol-treated primary acinar cells, demonstrating that EGCG can modulate pancreatic regenerating related genes. Therefore, our findings suggest that EGCG may have therapeutic utility in the prevention or treatment of alcohol-associated pancreatitis.

The 3D building modeling is one of crucial components in building 3D geospatial information. The existing methods for 3D building modeling depend mainly on manual photogrammetric processes by stereoplotter compiler, which indeed take great amount of time and efforts. In addition, some automatic methods that were proposed in research papers and experimental trials have limitations of describing the details of buildings with lack of geometric accuracy. It is essential in automatic fashion that the boundary and shape of buildings should be drawn effortlessly by a sophisticated algorithm. In recent years, airborne LiDAR data representing earth surface in 3D has been utilized in many different fields. However, it is still in technical difficulties for clean and correct boundary extraction without human intervention. The usage of airborne LiDAR data will be much feasible to reconstruct the roof tops of buildings whose boundary lines could be taken out from existing digital maps. The paper proposed a method to reconstruct the roof tops of buildings using airborne LiDAR data with building boundary lines from digital map. The primary process is to perform octree-based segmentation to airborne LiDAR data recursively in 3D space till there are no more airborne LiDAR points to be segmented. Once the octree-based segmentation has been completed, each segmented patch is thereafter merged based on geometric spatial characteristics. The experimental results showed that the proposed method were capable of extracting various building roof components such as plane, gable, polyhedric and curved surface.

Purpose: We comprehensively analyzed domestic studies on the effects of death preparation education in order to present objective data. Methods: Meta-analysis was conducted with a total of 22 master's and doctoral theses published between 2004 and 2014. Results: According to our analysis, the death preparation education had a mid-size effect. The effect size of a moderator variable was the greatest in infants and children, and the effect size was bigger in younger ages. The effect size was the greatest when education was given through a total of 10~15 sessions, twice a week, and less than 60 minutes per session. The effect variable and death-related variable showed a significant effect size, and sub-variables were equivalent to the death-related variable with a biggest effect size. Non-death related variables had a mid-level effect size and sub-variables were found to have the highest ego integrity. Conclusion: The significance of this study lies its systematic integration of advanced research on the effects of death preparation education through meta-analysis. By suggesting guidelines for the design of a death preparation education program, evidence-based basic data were proposed which will more likely strengthen intervention effects. Based on these results, more studies are needed to develop and extensively carry out a death preparation program which can meet needs of specific age groups from children to seniors.

The objective of this study is to examine the association of social networks and medical care utilization of elderly living alone depending on self-rated health status, and also to measure the moderating effects of welfare services for elderly. To this purpose, the data which was collected from the 2014 National Survey on Elderly in Korea was analyzed by Chi-square test and Poisson regression. According to the results, social networks and elderly welfare services affected to medical care utilization of elderly living alone, only who aware of their self-rated health status as bad. With this group, the frequency of contact with family and participation in lifelong education had a significant effect on increasing medical care utilization. In contrast, the frequency of contact with neighbors and the participation in elderly employment program were significant to reduce the utilization of medical care. Furthermore, the moderating effects of elderly welfare services were also measured that formal social gathering has an effect of increasing the medical care utilization of elderly living alone by expansion of their social networks. Based on these results, this study consequently has an implication for suggesting expansion of elderly welfare services, which might be an alternative to social networks of elderly living alone, and also for seeking the direction of political intervention that helps health promotion and disease prevention through the research of medical care utilization.

BACKGROUND/OBJECTIVES: This study aims to determine contribution of meal frequency, self-efficacy for healthy eating, and availability of healthy foods towards diet quality of adolescents in Kuala Lumpur, Malaysia. SUBJECTS/METHODS: This study was conducted among 373 adolescents aged from 13 to 16 years old. Diet quality of the respondents was assessed using the Healthy Eating Index for Malaysians. Meal frequency, self-efficacy for healthy eating, and availability of healthy foods were assessed through the Eating Behaviours Questionnaire (EBQ), self-efficacy for healthy eating scale, and availability of healthy foods scale, respectively. RESULTS: The majority of the respondents (80.7%) were at risk of poor diet quality. Males ($mean=34.2{\pm}8.2%$) had poorer diet quality than females ($mean=39.9{\pm}9.0%$) (t = -5.941, P < 0.05). Malay respondents ($mean=36.9{\pm}8.7%$) had poorer diet quality than Indian respondents ($mean=41.3{\pm}10.0%$) (F = 2.762, P < 0.05). Age (r = 0.123, P < 0.05), self-efficacy for healthy eating (r = 0.129, P < 0.05), and availability of healthy foods (r = 0.159, P < 0.05) were positively correlated with the diet quality of the respondents. However, meal frequency was not correlated with the diet quality of the respondents. Multiple linear regression analysis showed that being a male, being a Malay, low self-efficacy for healthy eating, and low availability of healthy foods contributed significantly towards poor diet quality among respondents. CONCLUSIONS: In short, sex, ethnicity, self-efficacy for healthy eating, and availability of healthy foods were associated with diet quality among adolescents. Health practitioners should take into consideration of differences in sex and ethnicity during implementation of nutrition-related intervention programs. Self-efficacy for healthy eating and availability of healthy foods should be included as important components in improving diet quality of adolescents.
