Purpose: This study was to evaluate the effects of a short term comprehensive life style modification program on glycemic metabolism, lipid metabolism and body composition in type 2 diabetes mellitus patients. Method: A nonequivalent control group with a pre post test was designed. Data collection was done from October 2003 to June, 2004 at a hospital. Glycemic metabolism was measured by a.c., p.c. and $HbA_{1}c$, and lipid metabolism was measured by cholesterol, HDL cholesterol, LDL cholesterol and triglycerides. Body Composition was measured by body weight, body mass index, waist, measurement waist per hip ratio, body fat, muscle weight and abdominal fat tissue(intra abdominal distance). The Experimental group, which was composed of 29 participants, was educated based on a life style modification protocol at a weekly meeting for 12 weeks and carried out exercise, diet along individual parameters and self monitoring, while 24 participants in the control group received only diet education. Result: 1. The experimental group showed a significant lower a.c.(t=2.11, p=.04) and $HbA_{1}c$(t=2.65, p=.01) compared to those of the control group. 2. The experimental group showed a significant lower LDL than the results of the control group(t=2.42, p=.02). 3. The experimental group showed a significant lower weight(t=3.09, p=.00), BMI(t=3.01, p=.00), body fat(t=2.94, p=.01) and abdominal fat tissue(t=3.05, p=.01) than those of the control group. Conclusion: The results provided evidence for the effectiveness of a short term comprehensive life style modification program composed of exercise, diet, support, self efficacy elevation and self monitoring in type 2 diabetes mellitus.

In this study, domains, contents, and effects of pre-existed intervention programs for individuals with arthritis were meta-analyzed to develop arthritis health promotion program based on Holistic Model. The developed program includes strategies of cognition, environment, and behavior. and also generates positive changes in the physical, psychological, and social demensions. Then needs assessment on conveniently selected 153 women who visited a university hospital in Seoul or in Inchon are conducted to identify the objective domains of arthritis health promotion program According to the study results. target health problems of the arthritis health promotion program were shown as pain, disability, depression, and role impediment in social domain. These objectives could be achieved by including the strategies of changing cognition, the strategies of changing behavior through learning the skill related to the health promoting behavior. and the strategies of changing environment in the health promotion program. That is, it is analyzed that the contents of program are not exclusive one another in physical. psychological. and social demensions, and also are not exclusive one another in aspect of cognition, behavior, and environment. The necessary methods to achieve the desired objectives for the developed arthritis health promotion program and evaluation subjects are as follows : (1) In the arthritis health promotion program, knowledge on management of arthritis, efficacy related to arthritis management, skill for pain management, skill for exercise, establishment of positive self-concept, enhancement of positive thinking, stress management. skill for problem solving, skill for setting goals. skill for requesting help, and skill for communication are all included. Through the improvement of all those strategies, intermediate objectives, such as “joint protection, and maintenance of pain management behavior”, “maintenance of regular exercise”, and “promotion of coping skill in psychosocial dimension” are achieved. (2) These intermediate objectives are also the methods for achieving objectives in next stage. It implies that through the intermediate objectives. the final objectives such as “minimization of physical symptoms and signs”, “maximization of psychological function”, and “maximazation of role performance in social domain” could be achieved. Each of these final objectives reflects the different dimension of quality of life, respectively. When these objectives are achieved, the quality of life that client perceives is improved. Therefore, through evaluation of these final objectives, the level of achieving final outcome of arthritis health promotion such as quality of life is determined.

The purpose of this study was to analyze womens' health problems using Green & Kreuter's 1991 PRECEDE model and to develop a model for a womens' health care center located in the community. The subjects were recruited from Wonju City. 1. The results showed that 23% of the sample population felt there was a need for a womens' health care center. The mean number of health problems was 3.1. The prevalence rate, was 44.4%, and the rate for an artificial abortion, was 36.4%. Also 30.5% did not have a health examination in the past year. Women using the hospital for medical care accounted for 45% of the sample, while 40% used the drugstore. The average score on the HPLP was 2.41, and this was influenced by self-efficacy, family support, sexual role, and health locus of control. There are a few educational programs in the city provided by the Wonju Health Center and by community health nurse practitioners. 2. The nursing center, as defined in North America, is a nurse-anchored system of primary health care delivery or neighborhood health center. Centers offer various services ranging from primary care to the more traditional such as education, health promotion, wellness screening, and coordination of services by advanced practice nurses. For examples in Sweden MCH centers provide total services for childbearing women and their families, sexual counseling and education for adolescents, and screening by midwives for cervical cancer. 3. The developed model combines purpose, target population, organization, and services, and is related to health resources. The purpose is primary health care and promotion of the quality of life. The target population can be grouped according to the life cycle, (premarriaged age group, the childbearing/child rearing age group, and middle aged and elderly women) and focuses on self-help. The organization of the center includes an advisory committee to plan and evaluate, and a health services team that will be multidisciplinary to provide health care, counseling education, and research. The model development suggested that a variety of women's health care centers are needed to insure adequate management of women's health. Follow-up research using PROCEED is needed to analyze health outcomes. Also a health nursing specialist system is required to develop health promotion, and improve the quality of life of women.

In this paper numerical stability of CSS and ISS schemes in axisymmetric fluid-structure-burning simulation for solid rocket motors are studied. The implemented CSS and ISS algorithms for two-dimensional axisymmetric FSI problems are used to analyze ACM and BCM solid rocket motors. Numerical results from CSS and ISS schemes are compared to investigate the efficacy of ISS scheme over CSS scheme in stabilizing the numerical solution. The ACM and BCM simulation results show that ISS scheme gives stable and converged numerical solutions with appropriately small system time step size, while CSS scheme fails to converge after generating rapidly amplified oscillatory solutions. It is concluded that ISS scheme can be useful in improving the numerical stability of FSI analysis for ACM and BCM solid rocket motor simulations, which is not successfully obtained with CSS scheme.

In the study, the effects of damping devices on damping ratio increase and wind-load reduction were investigated based on the computational platform, which is one of the parametric modeling methods. The computational platform helps the designers or engineers to evaluate the efficacy of the numerous alternative structural systems for irregular Super-Tall building, which is crucial in determining the capacity and the number of the supplemental damping devices for adding the required damping ratios to the building. The inherent damping ratio was estimated based on the related domestic and foreign researches conducted by using real wind-load records. Two types of damping devices were considered: One is inter-story installation type passive control devices and the other is mass type active control devices. The supplemental damping ratio due to the damping devices was calculated by means of equivalent static analysis using an equation suggested by FEMA. The optimal design of the damping devices was conducted by using the computational platform. The structural element quantity reduction effect resulting from the installation of the damping devices could be simply assessed by proposing a wind-load reduction factor, and the effectiveness of the proposed method was verified by a numerical example of a 455m high-rise building. The comparison between roof displacement and the story shear forces by the nonlinear time history analysis and the proposed method indicated that the proposed method could simply but approximately estimate the effects of the supplemental damping devices on the roof displacement and the member force reduction.

This article critically examines the backgrounds and meanings of National Competency Standards (NCS) that is employed by Korean colleges for managing performance-based, competency-based curriculum. Findings are as follows: 1) the NCS-based curriculum was primarily adopted to enhance students' business competency for their successes in a competitive job market. 2) NCS is questioned its efficacy to resolve Korean employment issues in a serious economic structure in which a growing number of jobless youth and aged employees and education discrimination are involved. 3) NCS, with its emphasis on the Tyler Rationale and principles of scientific curriculum development, has many criticisms due to its technical approaches to educational processes and needs to be replaced with an alternative paradigm. 4) This article suggests that administrators, policy makers, and educators seek ways to resolve NCS issues considering contextual features of Korean job market and rethinking NCS ideology in the education process. A need for curriculum reconceptualisation is discussed.

In this study, Zea mays L., which were discarded after harvesting in Korea, were collected and used for experiment. The Zea mays L. were dried in the shade and ground before being extracted using two solvents. Subsequently, DPPH, ABTS, the total flavonoid content and the total polyphenol content were measured to analyze antioxidant activity. The diameter of clear zone was measured by using the paper disc diffusion method. The results showed that the ethanol extract had a slightly higher antioxidant and antibacterial activity. The total polyphenol content was measured using gallic acid as standard, and CE(ethanol extract) was found to contain $31.2{\pm}5.2mg\;GAE/g$ of polyphenols, indicating a considerably high activity. When DPPH radical scavenging ability was measured, CE was found to have $4.6{\pm}0.9%$, $6.4{\pm}0.5%$, $22.9{\pm}0.6%$ and $83.2{\pm}0.2%$ at different concentrations of $1{\mu}g/mL$, $10{\mu}g/mL$, $100{\mu}g/mL$, and $1,000{\mu}g/mL$, respectively, with a dependent tendency at the concentration of $1,000{\mu}g/mL$ and a considerably high activity at the concentration of $1,000{\mu}g/mL$. This study is expected to be used as preliminary data to develop new natural antioxidant, antibacteria raw materials, as only little research has been undertaken on Zea mays L., which are mostly discarded after harvesting, while many studies have been so far conducted on corn and corn silks.

This study investigated the efficacy and drawbacks of a trekking accident prevention programs of the Jirisan National Park using visitor survey data. In total, 394 visitors were surveyed at the entrances to Seongsamjae, Jungsanri, Baekmudong, and Ssanggyesa trails on both weekdays and weekends. The trekking accident prevention training course has not been widely publicized. Only 23.4 % of the survey respondents have participated the training course. The training course itself appears to be useful in that 51.1 % of the course participants positively responded the contents of the course, suggesting that, if well publicized, the program can help prevent trekking accident. The trekking time regulation was relatively well publicized. Of the survey respondents, 72.4 % were aware of this regulation, and 72.2 % of them agreed on applying this regulation to other national parks. Accident vulnerability analysis shows that respondents who were aware of the regulation tend to be more experienced and skilled in trekking and more prepared for accident than those who were not. Also, respondents who were satisfied more on park safety facilities tend to be more experienced and skilled in trekking and more prepared for accident.

Occurrence status of Tetranychus viennensis Zacher was investigated in Kyonghuk province. Its ecological studies were carried out and chemical control efficacy against females and eggs was examined. And the results ohtained are as follows. T. viennensis occurred from mid April through mid November with the peak time in June on cherry tree. Population level of T. viennensis was varied from 0 to 160 individuals per 100 peach leaves in different peach orchards, and its occurrence rate was 35% out of 20 ochards. However no T. viennensis was observed from 25 apple orchards in 5 districts of Kyongbuk province. Overwintering stage of T. viennensis females appeared in mid October, and most of them moved into under the rough hark in early November. The overwintered adult females moved out from the rough bark to leaves in early April. Mortality during overwintering was about 55%. Under four constant temperatures of 16, 19, 22, 25$^{\circ}$C. egg periods were 14. 3, 9.2, 6.8, and 4.0 days ; larva -nymph periods were 20.2, 13.9, 8.7, and 6.6 days. Female longevity was 67. 7, 60.7, 46.4, and 34.0 days : mean tota: fecundities per female were 21.2, 44.3, 54.4, and 64.7 eggs. Some acaricides, azocyclotin, pyridaben, propargite, tehufenpyrad and fenpyroximate were highly effective against females, while hexythiazox and clofentezine showed very low control effect from 3.6 to 14.4%. Whereas, all of 7 acaricides tested highly effective against the eggs.

Background: During the past decades, the incidence and mortality rate of stomach cancer has demonstrated a great decrease in the world, but it is still one of the most common and fatal cancers especially among men worldwide, including Iran. The MYC proto-oncogene, which is located at 8q24.1, regulates 15% of genes and is activated in 20% of all human tumors. MYC amplification and overexpression of its protein product has been reported in 15-30% of gastric neoplasias. The aim of this investigation was to find the relative efficacy of CISH (chromogenic in situ hybridization) or IHC (immunohistochemistry) in diagnosis and prognosis of gastric cancer, as well as the relationship of amplification and expression of C-MYC gene with patient survival. Materials and Methods: In this cross-sectional study, 102 samples of gastric cancer were collected from patients who had undergone primary surgical resection at the Cancer Institute Hospital, Tehran University of Medical Sciences, from July 2009 to March 2014. All samples were randomly selected from those who were diagnosed with gastric adenocarcinomas. CISH and IHC methods were performed on all of them. Results: Patients were classified into two groups. The first consisted of stage I and II cases, and the second of stage III and IV. Survival tests for both groups was carried out with referrnce to CISH test reults. Group II (stage III & IV) with CISH+ featured lower survival than those with CISH- (p=0.233), but group I (stage I & II) patients demonstrated no significant variation with CISH+ or CISH- (p=0.630). Kaplan-Meier for both groups was carried out with IHC test findings and showed similar results. This data revealed that both diffuse and intestinal types of gastric cancer occurred significantly more in men than women. Our data also showed that CISH+ patients (43%) were more frequent in comparison with IHC+ patients (14.7%). Conclusions: For planning treatment of gastric cancer patients, by focusing on expanding tumors, which is the greatest concern of the surgeons and patients, CISH is a better and more feasible test than IHC, in regard to sensitivity and specificity. Therefore, CISH can be used as a feasible test for tumor growth and prognosis in stage III and IV lesions. This study also indicated that C-MYC amplification in gastric cancer is correlated with survival in advanced stages.
