The aim of the study was to identify which fall-prevention program offered in community settings in Korea is the most effective in strengthening muscles. Muscle weakness is one of the major risk factors causing falls among the elderly. Randomized controlled trials and clinical controlled trials published between 1996 and February 2011 were included in this study. Seventeen of the 69 identified studies met the study's criteria and were included in this meta-analysis. The overall effect size of the program was .822 (95% confidence interval= .717~.927). The general strengthening exercise (1.608), dance sports training (1.538), Thera-band exercise for lower extremities (1.517), Seniorobic exercise (1.146), gait training (.959), balance training (.909), gradual resistive exercise (.888), and multifactorial fall prevention (.842) programs all show positive effects on muscle strengthening. Subgroup analyses found that more relative effects are seen in programs offered to the more elderly. In this study, the effect of increasing muscle strength on the prevention of falls can only be indirectly suggested; there are few available studies that report the frequency or history of falls in Korea. Further studies are needed to examine the direct effect of fall prevention exercise programs among the elderly.

This study was carried out to compare the efficacy of sodium carboxymethyl cellulose (SCMC) with the combination of low molecular weight heparin (LMWH) and SCMC for the prevention of postoperative adhesions in the dog. After laparotomy, abrasions were made on the surface of ileal serosa in 17 dogs. The animals were randomly divided into the control group (N = 5) which received no treatment, the SCMC-treated group (N = 6), and the SCMC ＆ LMWH-treated group (N = 6). Hematologic values were monitored before laparotomy and 1, 4, 7, 10 and 14 days after laparotomy. The location and score of adhesion were assessed at second laparotomy 3 weeks later, Although the mean adhesion score both in the SCMC-treated group (7.17${\pm}$1.17) and in the SCMC & LMWH-treated group (4.50${\pm}$1.38) was found to be significantly lower than that in the control group (9.40${\pm}$0.89) (p<0.01 and p＜0.01, respectively), more favorable adhesion prevention was achieved in the SCMC ＆ LMWH-treated group in comparison with the SCMC-treated group without any hemor-rhagic complications (p<0.01). This study could conclude that SCMC ＆ LMWH are highly effective in prevention against postoperative adhesion in the dog.

Objectives: This pre-post quasi-experimental study was designed to investigate the effects of school based smoking prevention education on knowledge and attitude toward smoking, and the satisfaction of education among middle school students. Methods: The subjects included 94 middle school students in the experimental group. and 87 students in the control group. The educational content contained smoking refusal skills, which were taught through lectures and videos. Data collection was achieved using a self-reported questionnaire developed by the investigator. Data were analyzed with the SPSS 10.0 program including frequency, percentile, X2, paired t-test, and ANCOVA. Results: The results were as follows: 1. After the smoking prevention education, the smoking knowledge of the experimental group was significantly improved, whereas that of control group didn't change significantly. 2. There were no significant differences between pretest and post test attitude scores in both groups. 3. Refusal skill was the education content that provided the highest satisfaction for the subjects, and the degree of satisfaction was higher with video watching than with a lecture. Conclusion: Smoking prevention education for middle school students increased their level of smoking knowledge, but did not affect their attitudes toward smoking. Therefore, it is necessary to develop a more effective program, and to evaluate the effects of a long term education program with further studies.

This paper presents static output feedback LQ and $H_{\infty}$ controllers for rollover prevention. Linear quadratic static output feedback controllers have been proposed for rollover prevention in such a way to minimize the lateral acceleration and the roll angle. Rollover prevention capability can be enhanced if $H_{\infty}$ controller is designed. To avoid full-state measurement for feedback requirement or sensitiveness of an observer to nonlinear model error, static output feedback is adopted. To design static output feedback controllers, Kosut's method is adopted because it is simple to calculate. Differential braking and active anti-roll bar are adopted as actuators that generate yaw and roll moments, respectively. The proposed method is shown to be effective in preventing rollover through the simulations on nonlinear multi-body dynamic simulation software, CarSim.

Purpose: The purpose of this study was to develop a guide book on safety education for teachers to use in education classes for elementary school students. Methods: Dick & Carey's teaching model and Keller's ARCS theory were used in the development of this guide book. Results: This guide book was developed for lower grade (1st$\sim$3rd) and higher grade (4th$\sim$6th) elementary school students. The content consisted of subjects, worksheets, content for teachers, statistical data, case studies, and a safety letter to the parents. The 10 subjects were as follows: "Importance of injury prevention", "Safety at home", "Accident prevention at school", "Violence prevention", "Vehicles safety", "Water safety", "Prevention of Fires & Burns", "Safety of Toys & home supplies", "Safety in Sports & Recreation activity", "Prevention of injury caused by animals". Statistical data was presented by graphs and case studies were presented of cases of real occurrences of accidents. Worksheets contain various activities for students. Safety letters were composed for each student's parents. Conclusion: This guide book presents effective material for safety education classes in elementary school and the authors hope it will be widely used in elementary schools.

The supportive care of patients receiving antineoplastic treatment has dramatically improved over the past few years and development of effective measures to prevent nausea and vomiting after chemotherapy serves as one of the most important examples of this progress. A patient who starts cancer treatment with chemotherapy lists chemotherapy-induced nausea and vomiting as among their greatest fears. Inadequately controlled emesis impairs functional activity and quality of life, increases the use of health care resources, and may occasionally compromise adherence to treatment. New insights into the pathophysiology of chemotherapy-induced nausea and vomiting, a better understanding of the risk factors for these effects, and the availability of new antiemetic agents have all contributed to substantial improvements in emetic control. This review focuses on current understanding of chemotherapy-induced nausea and vomiting and the status of pharmacological interventions for their prevention and treatment.

Cervical cancer remains the most frequent cancer in women from the developing world. More than 88% of deaths occur in low-income countries, and it is predicted to climb to 91.5% by 2030. Although Pap-based screening programmes have shown to be effective in reducing the disease burden in high-resource countries, implementation and sustention of cytology-based programmes is quite challenging in low-resource settings. The present paper reviews evidence-based alternatives of screening methods, triaging algorithm, treatment of cervical precancerous lesions, and age-group at screening appropriate for low-income countries. Evidence shows that visual inspection methods using diluted acid acetic or Lugol's iodine, and HPV-DNA testing are more sensitive tests than the Pap-smear screening test. Visual inspection allows an immediate result and, when appropriate, may be immediately followed by cryotherapy, the so called "screen-and-treat" approach, achieved in a single visit, by trained nurses and midwives. Examples of cervical cancer prevention programmes in India and selected low-income countries are given.

Objectives: This study was conducted to investigate the effectiveness of a class-based school violence prevention program for elementary school student. Methods: 29 students were assigned to the school violence prevention program of 8 sessions, 28 students have been assigned to the control group. We assessed participants at baseline and post-intervention, through their self-report questionnaires such as Children's Depression Inventory (CDI), Strengths and Difficulties Questionnaire and school violence experience, awareness about school violence, and coping ability to school violence. We compared the baseline and post-intervention result of each group and compared the post-test scores between the intervention group and the control group. Results: Comparing the intervention group and the control group, the post-intervention CDI total score and the awareness about school violence showed significant improvement in the intervention group. When compared according to gender, male students' perception of school violence was improved, and female students showed significant differences in CDI scores. Conclusion: The CDI total scores and the perception of school violence were improved in the intervention group compared to the control group. And there are differential pattern of intervention effects according to gender. These findings have important implications to develop effective violence prevention programs.

Purpose: This study was to develop an effective evaluation tool for evaluation of hypertension prevention and management program(HPMP) in community health posts (CHPs). Method: Evaluation tool composed from the literature review, the field visiting, and the in-depth interviews with the community health practitioners. Result: The evaluation tool had four domains, each with different maximum points:, hypertension prevention (35), hypertension management (40), environment of the CHPs(10), and evaluation system of the HPMP(15). The first domain was hypertension prevention with sub-domains of health education, and early detection of patients with hypertension. The second domain was hypertension management with sub-domains of management of health records of patients, education and counseling, and treatment and follow-up of patients. The third domain was the environment of the CHPs with subdomains of accessibility of CHPs to residents, accessibility of general health data to the public, and availability of health information to the public by multimedia. The fourth domain was the evaluation system of the HPMP with the subdomains of planning of program, formative evaluation, process evaluation, and summative evaluation. Conclusion: The newly developed evaluation tool will contribute not only to plan and set goals for evaluation of HPMP in CHPs.

Past and current customer behavior is the best predicator of future customer behavior. This paper introduces a procedure on personalized defection detection and prevention for an online game site. The basic idea for our defection detection and prevention is adopted from the observation that potential defectors have a tendency to take a couple of months or weeks to gradually change their behavior (i.e. trim-out their usage volume) before their eventual withdrawal. For this purpose, we suggest a SOM (Self-Organizing Map) based procedure to determine the possible states of customer behavior from past behavior data. Based on this representation of the state of behavior, potential defectors are detected by comparing their monitored trajectories of behavior states with frequent and confident trajectories of past defectors. The key feature of this study includes a defection prevention procedure which recommends the desirable behavior state for the ext period so as to lower the likelihood of defection. The defection prevention procedure can be used to design a marketing campaign on an individual basis because it provides desirable behavior patterns for the next period. The experiments demonstrate that our approach is effective for defection prevention and efficient for defection detection because it predicts potential defectors without deterioration of prediction accuracy compared to that of the MLP (Multi-Layer Perceptron) neural network.
