This study covers an investigation using meta-analysis of the factors related to the effects of singing activities for children, focusing on the dissertations conducted for master and doctor degrees and the studies published in academic journals over the past 16 years. Ameta-regression analysis was conducted to examine the changes of the factors in each published year. The analysis results were as follows: Both the entire effect size and the groups of singing activity related factors were revealed to have significant effect sizes. While the group of social factors and the group of cultural & artistic factors showed large effect sizes, the group of psychological & emotional factors appeared to have an intermediate effect size. The sub-factors of the group of social factors were shown to have significantly larger effect sizes than the others, except for the factor of capability of recognizing others. Among the sub-factors, naturally friendly behavior showed relatively larger effect size than the others. In the sub-factors of the group of psychological & emotional factors, self-expression capability and self-control capability showed large effect sizes and stress suppression and emotional intelligence showed intermediate effect sizes. Among the sub-factors of the group of cultural & artistic factors, except for creative capability which showed an intermediate effect size, all of the sub-factors showed large effect sizes. According to the results of the analysis of the trend of the effect size changes in each published year, the trends of the entire effect size and the effect size of each factor, such as the groups of social factors, psychological & emotional factors and cultural & artistic factors, showed that the activity effects increase as the publication year comes closer to the most recent year.

This study was designed to investigate the changes in energy substrates, glucose and non-esterified fatty acid(NEFA), and fatty acid compositions in serum, following physiolgical stress in rats fed diets containing various fatty acids. Forty two Sprague-Dawley strain male rats, weighing 108$\pm$2.1g, were fed 3 different experimental diets for 4 weeks. The diets were composed of 105 fat(w/w) of either corn oil(CO;18:2 n6:57%), plant perilla oil(PO;18:3 n3:59%), or tuna fish oil(FO;20:5 n3:17%%, 22:6 n3:19%). After 4 weeks of feeding, each group wa subdiveided into (a) control, (b) 2 min swim in ice-cold water. Animals wer decapitated 20min after commencing the swim; trunk blood, brain, liver and epididymal fat pad were obtained. The levels of serum corticosterone, glucose, NEFA, triglyceride, fatty acid compositions, brain serotonin and 5-hydroxyindoleacetic acid were determined. Basal levels of corticosterone na NEFA of serum were significantly lower in fish oil fed animals than those of any other oil fed animals. Compared to either perilla oil-fed or corn oil-fed rats, cold swim stress in fish oil fed rats produced significantly smaller NEFA and larger corticosterone responses. However, there was no significant difference in basal levels of serum glucose. Stress increased serum glucose levels slightly, and the amount of increment was larger in fish oil rats than those of any other oil fed rats than those of any other oil fed rats, although all the values were normal level. Dietary fats and stress did not affect serotonin metabolism. In additions, the composition of fatty acids in serum was significantly affected by the dietary compostion of fatty acids and stress. Stress induced decreases in monounsaturated fatty acid and non-polyunsaturated fatty acid concentration in either perilla oil fed or fish group, but did not in corn oil fed group. Stress resulted in changes in fatty acid metabolism similar to that associated with essential fatty acid(EFA) dificiency, when feeding animals n-3 fatty acids in diet. In conclusion, feeding fish oil was more effective to decrease NEFA in serum than feeding perilla oil or corn oil and improved lipid metabolism, when the rats were maintained in normal or exposed to stressful environment. However, the fact that feeding diet containing n-3 fatty acids decreased EFA status under stress suggests that the requirement of n-6 PUFA should be increased in these groups.

12주간의 유산소 운동 및 복합성 운동이 중년여성의 신체 구성 및 혈중 지질에 미치는 영향을 규명하기 위해 2009년 3월부터 9월까지 일개 D광역시 소재 일개 S구 보건소 12주 운동프로그램에 참가한 40~50대 중년 여성 78명을 대상으로 비만그룹과 정상그룹으로 나누어 주3회, 회당 80분의 유산소 운동과 유산소운동/근력 운동을 병행한 복합성 운동을 목표 심박수 40~60%에서 실시하였다. 1. WHO 기준 적용 시, 정상군의 경우 운동의 유형에 상관없이 유의한 차이가 나타났다. 2. WHO 기준 적용 시, 비만군의 경우 유산소 운동의 근육량, 체지방량, 체지방률을 제외하고 운동의 유형에 상관없이 유의한 차이가 나타났다. 3. 아시아-태평양 기준 적용 시, 정상군의 경우 일부 항목에서만 유의한 차이가 나타났다. 4. 아시아-태평양 기준 적용 시, 비만군의 경우 유산소 운동의 근육량을 제외하고 운동의 유형에 상관 없이 유의한 차이가 나타났다. 상기 결론에서 볼 수 있듯이, 12주간의 운동 프로그램은 WHO 기준 적용 시 일부 항목을 제외하고 운동 유형에 상관없이 40~50대 중년여성의 신체조성 및 혈중지질에 긍정적 효과를 미치는 것으로 판단된다. 그러나 비만에 대해 더 엄격한 아시아 - 태평양 기준 적용 시 특히 정상 군에서 유의한 차이를 보이지 않는 항목이 많이 나타났는데 이것은 우리나라 비만기준을 아시아태평양기준에서 세계 기준으로 바꿀 필요가 있다는 주장을 뒷받침하고 있다. 세계보건기구 WHO는 2004년에 이미 우리나라에 세계비만기준을 따를 것을 권고했는데, 실제 위험성이 정확하게 평가돼야지 정확한 대책이나 관리가 나올 수 있기 때문이다. WHO 기준에 의거 시 질병의 발생 위험도가 낮은 경도비만이 엄격한 아시아-태평양 지역 기준 적용 시 비만으로 분류되어 불필요하게 체형에 대한 부정적인 이미지나 스트레스를 받을 가능성도 있다.

The aim of this study was to identify the effective factors for improving the professionalism of the social welfare public organization and to suggest the implications for the relationship between public social welfare and educational alternatives. For the analysis, 637 government officials who worked in the social welfare department of local governments in Kangwon province were surveyed. Based on previous studies on the organizational effectiveness, this study examined differences in the perceptions of job stress, organizational satisfaction, organizational commitment, and social support by characteristics (gender, major, and serial), followed by relationship educational alternatives (job training, healing camp, psychological counseling). The differences according to gender were significant only in the creativity of the work and the self-esteem of the institution. Through the confirmation of recognition difference according to whether they majored or not, it was confirmed that expertise of the major in social welfare was necessary for job performance ability and suggested the urgency of the appointment of a major. The differences among the serials showed that administrative work is more difficult than social welfare work in terms of professionalism and expertise. Finally, based on the results of the causal relationships with educational alternatives, this paper introduces and operates systematic educational programs, such as personal psychological counseling and organizational healing camp management, as well as the need for active and proactive responses to changes in social welfare administration organizations.

This study was performed to obtain the basic data on physiological responses of low water temperature stress of the cultured Pacific abalone, Haliotis discus hannai. Abalones were exposed at low water temperatures of $7^{\circ}C$ and $4^{\circ}C$. We have investigated survival rate, superoxide dismutase (SOD) activity and total protein (TP) in the abalone by the exposure times (0, 3, 6, 12, 24, 72, 120, 168 and 216 hours). Survival rate of the abalone at $7^{\circ}C$ experiment was 90.8%, whereas at $4^{\circ}C$ experiment was 0% after exposure 10 days. SOD activity was significantly increased until 12 hours after exposure to $4^{\circ}C$, and then was recovered to starting level after 24 hours. However, there was no significant difference between control ($12^{\circ}C$) and $7^{\circ}C$ experiments. TP was significantly increased until 216 hours after 24 hours at $4^{\circ}C$ experiment, but $7^{\circ}C$ experiment showed no significant differences compared to control ($12^{\circ}C$) experiment. Therefore, H. discus hannai was acclimated in low water temperature stress at $7^{\circ}C$, but at $4^{\circ}C$, all abalone died possibly because they exceed the limits of defense ability to too low temperature.

Korean bennudagrass collections showed diverse genetic variations in their morphology, growth habit, and cytological aspects. Chromosome number and nuclear DNA content of the bennudagrasses indicated a ploidy level ranging from triploid (2n=3x) to hexaploid (2n=6x). In this study, we investigated the different responses of antioxidant enzymes (superoxide dismutase, catalase, peroxidase, ascorbate peroxidase) and cell membrane stability of those bennudagrass cytotypes to lower temperature and shorter day length, which meets a dormant induction in Korea. All the antioxidant enzymes were found to be higher during dormant stage, while the heme-containing catalase which converts hydrogen peroxide ($H_2O_2$) to water and oxygen molecules was activated before dormant initiation in the three cytotypes except for hexaploid bennudagrass. The triploid and tetraploid which exhibited relatively finer leaves and a rapid establishment speed were found to show increased activities of superoxide dismutase and peroxidase enzyme. The malondialdehyde(MDA) which is a product of lipid peroxidation in the cell membrane damaged by the hydroxyl radical was increased in all cytotypes as temperature declined, and tri- and tetraploids which had more protective antioxidant enzymes demonstrated a significantly lower MDA production. Similarly electrolyte leakage was higher in penta- and hexaploidy, seemingly more damage to cell membrane when low temperature was implemented. Results indicated that antioxidant responses of different cytotypes were genetically specific, which needs to be investigated the relevance with the low temperature tolerance in the bermudagrass further at the molecular level.

Purpose : The purpose of this study was to evaluate the clinical results of bone-patellar tendon-bone(B-PTB) allograft for ACL reconstruction without mechanical tensioning device. Material and Method : Forty-six knees in 43 patients were reviewed and evaluated with subjective evaluation, objective evaluation, Telos stress arthrometer and modified Feagin Scoring System. The average age at the time of operation was 27 years(range, 18-42) and the average follow up period was 41 months(range, 22-79). Authors reconstructed ACL using B-PTB allograft which was prepared by rehydration preoperatively without tensioning by mechanical tensioning device. The tension for allograft was obtained by full flexion and extension intraoperatively. All operation were performed arthroscopically by two-tunnel method to avoid the mismatching of allograft tendon length. Result : The modified Feagin Scoring System revealed 39 cases(84.7%) with excellent or good results and 7 cases(15.3%) with fair or poor results. The mean follow-up Lysholm Knee Score was 84. Telos arthrometer revealed 41 cases had an injured-to-uninjured difference of 5 mm or less(mean 2.3mm). The range of motion of knee was nearly normal and there was no extension lag in any cases at last follow up. Conclusion : Clinical results using B-PTB allograft showed less morbidity than B-PTB autograft. The intraoperative tensioning method by full flexion and extension without mechanical tensioning device was not bad. Therefore, B-PTB allograft is a good substitute material in reconstruction of the ACL.

Objectives : Fatigue is a common symptom in primary medical care and has nonspecific and highly subjective features. So it has been difficult to define and measure fatigue, especially those present without any organic diseases. This study was conducted to evaluate the validity of the Fatigue severity scale(FSS) in patients with persistent fatigue who were free of any organic diseases or psychiatric disorders of depression or anxiety. Methods : Subjects consisted of 45 controls, 44 fatigued patients and 43 psychiatric patients with depression or anxiety. They all completed the fatigue severity, modified Bepsi stress, and Hospital anxiety and depression scales. Chalder fatigue scale was administrated randomly in 30 of them. Data were analyzed for reliability and validity of the FSS. Results: Cronbach's a coeffient of FSS was 0.929, and the Pearson correlation coefficient for test-retest was 0.916(p<0.01). ANCOVA for discriminant validity revealed that there were significant differences in mean FSS values among the three groups. The fatigue group had significantly higher FSS value than the other two groups. The psychiatric group also had significantly higher FSS value than the control group. The Pearson correlation coefficient for convergent validity by comparing FSS with Chalder fatigue scale was 0.782(p<0.01). Using FSS index 3.22 as the cut-off point, sensitivity was 84.1% and specificity was 85.7% for the fatigue and control groups, respectively. Conclusion : Results suggested the clinical application of the FSS to be a useful measurement for distinguishing fatigue between patients with physiologic fatigue and psychiatric patients with depression or anxiety.

Objectives : With the increase in cancer prevalence, the health behavior of cancer survivors has become an important issue. This study was conducted to examine the psychosocial correlates of behavior changes after cancer diagnosis. Methods : 95 patients completed questionnaires assessing depression, anxiety, insomnia, posttraumatic stress symptoms, social constraints, personal beliefs about cancer cause and health-related behavior changes after cancer diagnosis. Results : In the multiple logistic regression analysis, insomnia was the only significant predictor of positive change in physical behavior : normal sleep group(Odds ratio=9.462, 95% CI 1.738-51.509) and subthreshold insomnia group(Odds ratio=10.529, 95% CI 1.701-65.161) showed a larger increase compared to the insomnia group. In psychosocial behavior, low age, religion and causal belief in hormonal factors were independent factors that predicted increase in positive change. Conclusions : This study showed a difference between predictors of physical and psychosocial health behavior change after breast cancer diagnosis. Multi-faceted approaches are required to promote positive change in health behavior in cancer patients.
