Objectives: To compare the efficacy of two types specific exercise intervention (deep and superficial abdominal muscle exercises) in the treatment of patients with chronic low back pain (CLBP). Design: A randomized, comparative, repeated-measures. Subjects: Twenty-four patients with CLBP (at least for 3 months), mean $age{\pm}SD=51.58{\pm}16.21$ (yrs). Methods: Twenty-four patients with this condition were assigned randomly to two treatment groups. Both first and second group underwent 3 weeks specific exercise treatment program. The first group specific trained for the deep abdominal muscles. The second group specific trained for the superficial abdominal muscles. Results: After intervention, the first group showed a statistically significant reduction in pain intensity and functional disability levels (p<.05). The second group showed no significant change in these parameters after intervention (p>.05). Conclusions: According to results, a "deep abdominal muscle exercises" treatment approach appears more effective than a "superficial abdominal muscle exercises" treatment in patients with CLBP.

Purpose: The aim of this study was to identify the effects of a newly developed instructional coaching program regarding Attention Deficit Hyperactivity Disorder (ADHD) for teachers. Methods: Seventy teachers participated in this study involving a nonequivalent control group and a pretest-posttest design. The instructional coaching program consisted of eight 60-minute sessions. The program was developed through a theoretical development program involving six steps. To evaluate the effects of the program, data were collected through self-report questionnaires including the Knowledge Scale of Attention Deficit Disorder, Attitude Scale of Primary School Teachers Experiencing Students with ADHD, Practice Scale of Educational Intervention Activity, and the Korean ADHD Rating Scale. Data were analyzed with an independent t test, a chi-square test, and an ANCOVA using SPSS WIN version 20. Results: The intervention program consisted of 3 sectors, 8 subjects, and 24 content items. The experimental group showed a significant improvement in attitudes toward ADHD (F=22.83, p<.001). In addition, teacher's knowledge regarding ADHD (F=7.16, p=.010) and the implementation of instructional interventions (F=4.29, p=.043) improved. Further, teachers reported a reduction in children's ADHD-related behavior (F=4.34, p=.041). Results showed that the coaching program made a positive contribution to teaching skills and understanding of school-age children with ADHD. Conclusion: The instructional coaching program was well structured and significantly improved not only teachers'attitudes, knowledge, and teaching skills but also the behavior of children with ADHD in class. Therefore, the program is recommended as a means of facilitating teaching and managing children with ADHD in class.

Frozen food processing workers work under a cold environment which can cause several adverse health effects.This study explored factors affecting workers' health in the frozen food industry in Thailand. Participants comprised 497 workers exposed to a cold working environment and 255 office workers who served as the controls. Data were collected by a survey on the work environment, and the interview of workers for abnormal symptoms. The exposed group had the following characteristics: 52.7% male, overall average age of 27 (SD 6.6) years old, attained elementary education (Grade 4 and Grade 6) (54.1%), married (48.9%), smokers (21.3%), alcohol consumption (31.0%), duration of work was between 1 and 5 years (65.2%), working 6 days a week (82.7%), 1-5 hours of overtime per week (33.8%), office workers (33.9%); work category: sizing (6.9%), peeling (28.3%) dissecting (22.2%), and in the warehouse (8.6%). The temperature in the work environment ranged from $17.2^{\circ}C$ to $19.2^{\circ}C$ in most sections, $-18.0^{\circ}C$ in the warehouse, and $25^{\circ}C$ in the office areas. Warehouse workers had more abnormal symptoms than controls including repeated pain in the musculoskeletal system (OR 11.9; 95% CI 6.12-23.45), disturbance throughout the body (OR 4.60; 95% CI 2.00-10.56), respiratory symptoms (OR 9.73; 95% CI 3.53-26.80), episodic finger symptoms (OR 13.51; 95% CI 5.17-35.33). The study results suggest that workers' health should be monitored especially with regard to back and muscle pain, respiratory symptoms, episodic finger symptoms, and cardiovascular symptoms. Health promotion campaigns such as antismoking and reduction of alcohol consumption should be established because smoking and alcohol consumption are contributing factors to the pathogenesis of Raynaud's phenomenon and peripheral vascular disorders such as hypertension and heart disease.

국내의 장애인들이 많이 사용하고 있는 보조기구 중의 하나인 전동휠체어는 우리나라의 KS P ISO 7176-5 규격의 치수를 따르고 있으며, 이 규격의 경우 국제 규격인 ISO 7176-5의 규격을 기술적 변경 없이 그대로 사용하고 있다. 하지만 국제규격의 경우는 외국의 신체사이즈를 기준으로 휠체어에 대한 크기를 규정하기 때문에 국내에서 사용하기에 적합하지 않으며, 이로 인해 움직임의 제한 또는 골반의 회전으로 인한 자세 불균형, 허벅지에 과도한 압력으로 인한 욕창 발생 또는 오금 및 장딴지에 과도한 압력으로 인한 욕창발생, 바르지 못한 자세로 인한 안전성 감소 등이 발생한다. 본 논문에서는 기술표준원에서 조사된 연령별 인체치수를 토대로 전동휠체어의 권장휠체어 치수를 제안하였으며, 이는 KS P ISO 7176-5에 규정된 치수와는 많은 차이를 보이며, 전동휠체어 치수에 대한 재규정이 필요하다.

The purpose of this study was to compare the dietary status of elderly people according to the degree of obesity and mid-arm circumference in order to provide individualized and efficient nutrition management according to the physical condition of the elderly. Among the total 328 subjects, 72.2% were female, and the mean age and body mass index of the subjects were 76.5 years and $23.4kg/m^2$, respectively. The distribution of obesity degree was 47.9% for the normal group, 23.5% for the overweight group, and 28.7% for the obesity group. The distribution of mid-arm circumference was 18.0% for the under-21 cm group, 37.2% for the 21~22 cm group, and 44.8% for the over-22 cm group. About 82.9% of the subjects were consumed at least three meals a day, and 67.8% of the subjects regularly ate alone. The responses for meal time, regular meal, and meal reduction for 3 months were highest in the 10~20 min. (43.4%), yes (79.3%), and no (58.5%) group, respectively. The responses for eating alone were significantly highest in the overweight group (97.4%), followed by the normal group and obesity group according to the degree of obesity (P<0.05). There were no significant differences in preference for five flavors according to the degree of obesity and mid-arm circumference. Among the dietary habits, 31.1% of all subjects ate milk and dairy products more than once a day, and the response for eating vegetables and fruits more than three times a day was highest in the over-22 cm group (61.9%) while the drinking rate was highest in the under-21 cm group (27.1%; P<0.05). In conclusion, the degree of obesity was related to eating ability, and mid-arm the circumference was related with fruit and vegetable consumption and drinking rate.

Purpose: The purpose of this study was to develop a 12-week structured exercise program (12-week-SEP) and evaluate its effects on pain, physical function and quality of life in patients with total hip arthroplasty (THA). Methods: A nonequivalent control group non-synchronized design was utilized to examine the effects of the 12-week-SEP on patients' outcomes after THA. A total of 46 adult patients (experimental group=25, control group=21) who had THA were recruited for the study. The 12-week-SEP consisted of education, exercise (muscle strengthening and progressive walking), and feedback. Data were analyzed by SPSS/WIN 21.0 using the $x^2$ test and repeated measures ANOVA. Results: The mean age of the participants was 60.9 years and 25 men (54.5%) and 21 women (45.7%) were included in the study. There were significant intervention effects on pain reduction and increased physical function but no effects on quality of life. Conclusion: The 12-week-SEP provided pain relief and enhanced physical function in patients underwent THA. Clinical application of the 12-week-SEP can improve postoperative nursing practices for patients with THA. Future research with larger sample is of necessity to obtain greater generalizability of the empirical evidences of the 12-week-SEP.

The purpose of this paper is to investigate the determinants of the Operational Self-Sustainability (OSS) of Vietnamese microfinance institutions (MFIs). This research uses both qualitative and quantitative research methods: (i) qualitative research was via in-depth interviews with ten microfinance practitioners, policymakers and researchers; (ii) quantitative research was conducted by using panel data of 34 MFIs in the period 2011-2015 with binary logistics and OLS regressions. Results are as follows: (i) MFIs' OSS in Vietnam are mainly determined by five key factors: portfolio at risk (PAR>30), capital structure, gross loan portfolio, scope of activities and legal form; (ii) OSS are most affected by legal status (social organizations have better OSS than formal MFIs or programs/projects), location (MFIs focus in one province have higher OSS than working nationwide or just in one district), capital structure (MFIs with more equity proportion have higher OSS); (iii) surprisingly, average loan size per borrower and age of MFIs do not have statistically significant correlation with OSS. The key recommendations are: (i) MFIs should focus on its professionality and increase its equity; (ii) related stakeholders such as State Bank of Vietnam should promote the enabling ecosystem for microfinance development to enhance poverty reduction and economic development.
