  • This quasi-experimental study was intended to test the effect of self-help group program, which is one of the way to enhance adaptation and quality of life to mastectomy patients. Data was collected from July 14, 1998 to Oct. 31, 1998 at two Medical Center in Seoul. The subjects for this study were the patients who had undergone mastectomy and were follow-up ; 14 in experimental group and 14 in control group matched with age and treatment. The instruments for this study were adaptation in Lee(1994)'s physical symptom questionnaire, Zung's Self-rating Depression Scale(SDS, 1965), and Self-rating Anxiety Scale(SAS, 1970), quality of life in Spranger(1996)'s and No(1988)'s Quality of Life Questionnaire. The self-help group program for mastectomy patients was developed based on literature review and pilot study by the investigator. The subjects of experimental group were participated in 6 weeks self-help group program and were received arm and shoulder exercise, informational support, and interpersonal support by group members. The control group were received no intervention, Both group answered questionnaires prior to intervention and 6 weeks later. The data analyzed by frequency, $X^2$-test, Mann-Whitney U test. Wilcoxon Signed Rank test, Pearson's Correlation Coefficient and Stepwise Multiple Regression using SPSS WIN. The results are as follows ; Hypothesis 1. "The experimental group with the self-help group program will have a higher score on adaptation state than control group." was not supported. But the post test score of anxiety and depression in experimental group were declined and the depression score was reduced relatively. Hypothesis 2. "The experimental group with the self-help group program will have a higher score on quality of life than control group." was not supported. But the posttest score of quality of life in experimental group was reduced relatively. Hypothesis 3. "The higher adaptation state of mastectomy patients, the higher quality, of life." was supported(r=,80, p<.001). Additionally, the lower physical symptom, depression and anxiety, the higher quality of life And depression, which was the main predictor of quality of life, accounted for 59.5%, depression and anxiety accounted for 65.5% of the variance in quality of life. In conclusion, when the self-help group program was intervened to mastectomy patients, it was tended to increase quality of life and to reduce depression and anxiety. So self-help group program can be considered useful nursing inter vention effect on adaptation and quality of life of mastectomy patients. With discussion, I suggest repeated further re search on self-help group with appropriate sample size and longitudinal study. Also during adjuvant therapy, it is needed to develop convenient method to be supported from peer group and family, such as computer mediated support group.

  • The purpose of the present study was to determine the preventive effects of combined interventional trial of fish oil treatment and exercise training on insulin resistance of skeletal muscle in high-fat fed rats. Male Wistar rats were randomly divided into chow diet (CD), high-fat diet (HF), high-fat diet with fish oil (FO), high-fat diet with exercise training (EX), and FO+EX groups. The rats in control group were fed chow diet containing, as percents of calories, 58.9% carbohydrate, 12.4% fat, and 28.7% protein. High-fat diet provided 32% energy as lard, 18% as corn oil, 27% as carbohydrate and 23% as casein. The fish oil diet had the same composition as the high fat diet except that 100 g menhaden oil was substituted for corn oil. Insulin sensitivity was assessed by in vitro glucose transport in the soleus muscle after diet treatment and treadmill running for 4 weeks. While the FO or EX only partially prevented insulin resistance on glucose transport and visceral obesity induced by high-fat diet, these interventions completely corrected hyperinsulinemia and hyperglycemia from the high-fat diet. The rats in the FO+EX showed normalized insulin action on glucose transport, plasma chemicals and visceral fat mass. Insulin-mediated glucose transport was negatively associated with total visceral fat mass (r=-0.734; p<0.000), plasma triglyceride (r=-0.403; p<0.05) and lepin (r=-0.583; p<0.001) concentrations with significance. Multiple stepwise regression analysis showed that only total visceral fat mass was independently associated with insulin-mediated glucose transport (r=-0.668; p<0.000). In conclusion, combined interventional trial of FO+EX recovered insulin resistance on glucose transport of skeletal muscle induced by high-fat diet. Visceral fat mass might be more important factor than plasma TG and leptin to induce insulin resistance on glucose transport of skeletal muscle in high-fat fed rats.

  • There exists a remarkable differences in use of MRI scanning among income classes. The poor can hardly utilize it. This is because, among high cost technnologies, MRI is the only equipment not covered under health insurance benefits in Korea. This study was designed 1) to reveal the status of nation-wide MRI installation, customary charges and per unit annual scanning performance, and 2) to analyse factors influencing the above variables. The data for this study came from "MRI Prevalence Survey" conducted by the National Federation of Medcial Insurance(NFMI) in 1997, and were analyzed through SAS packages for T-test, analysis of variance and stepwise multiple regression. Data were collected from 188 hospitals equipped with MRI scanners. Major findings are summarized as follows : The number of MRI scanners has increased from 69 in 994 to 158 in 1996(2.3 times) while per unit annual scanning performance has risen by 11.2% from 2,173 cases in 1994 to 2,417 cases in 1996. Such a rapid increase was made possible mainly due to the inclusion of CT scanning under the health insurance benefit package. The customary charges for MRI scanning with or without contrast media, on average, amounted to 484,000 Won and 402,000 Won, respectively, with the percentile increase of 17.8% and 8.1% each during the same time. Korea ranks the third worldwidely in terms of number of MRI installations, 4.8 scanners per one million persons, only next to Japan and United States. Geographical variation of MRI, however, was rather high, 7.91 unit, in Cheju area compared to 1.82 in Kyongnam area. Variations of customary charges of MRI scanning can be explained as much as by 44.8% by both the total amount of claims to NFMI and geographical variable. The charges were more likely to be higher in metropolitan areas like Seoul and in hospitals with a bigger amount of claims. While those of per unit annual scanning performance can be explained as much as by 30.7% by both MRI installation cost and level of MRI-installed organizations. Per capital scannig performance was higher in tertiary hospitals and hospitals equipped with more expensive scanners than hospitals with less expensive scanners. Two measures are called for the remedying the existing excessive abundance in MRI units in korea : One is to set a ceiling of MRI units in an area like a province or a metropolitan district. The other is to establish a committee on introduction of high cost technologies for reviewing its effective use.ctive use.

  • The objective of this study was to analyze dietitians' sanitary practices and perceptions of obstacles according to HACCP. Questionnaires were administered to 94 elementary school dietitians in the Gwangju and Jeonnam Regions of South Korea. The data were evaluated by a 5 scale Likert method and statistically analyzed The results of the study are as follows. Each subject was generally characterized as a university graduate 79.8%, with 10 to 15 years experience 37.6%, and in her mid to late thirties 39.4%. We found that direct management was the highest occurring form of food service system 96.8%. With regards to the type of food service operation quantitative service as 60.6%, and partial self-service was 30.9%, 89.4%of all served only lunch. In all, 93.6% of the teams collaborated, while their organic collaboration was 64.9%. When HACCP was applied, sanitary practices scored an average of 4.83, which was significantly higher than 4.62 when HACCP was not applied. The dietitians' perception of sanitary practices was as very high 4.75 of 5. Sanitation, in regards to food management, scored 4.89 among the detailed items. This proves that in relation to food management, sanitation is considered most important. When HACCP was not applied, the perception of obstacles was, on an average, 3.07, which was higher than 2.74 when HACCP was applied. The results for the detailed items, which focused on sanitary practices and different perceptions of obstacles according to HACCP, were as follows. When HACCP was applied, a high mean of 3.32 occurred for facilities and utilities shortages followed by degree of cooperation at 3.22, and then monitoring at 3.01. The item that dietitians viewed as the biggest obstacle was lack of departmental budget support (M=3.46). Other serious obstacles were facilities, facility sanitation, and utility shortages (M=3.38), as well as the aappropriateness of machines and cooking utensils and arrangements in the dining room (M=3.28). Stepwise multiple regression was used to better understand how much these perceptions of obstacles would influence sanitary practices when HACCP was applied. The item analysis of the HACCP obstacles proved that persons involved in food service, except the food service employees, didn't cooperate enough with their food service employees. As a result, this lack of cooperation had a negative effect on sanitary practices. Accordingly, it is necessary to determine the causes of for lack of cooperation and attract the active attention of those involved.

  • Objectives : This study was performed to understand smoking condition and to investigate the relations among knowledge regarding smoking and oral hygiene, awareness of anti-smoking policy, and self-esteem, to provide fundamental basis, developing programs for smoking prevention and anti-smoking. Methods : From September 7, 2010 to September 16, 2010, questionaire survey was conducted for 566 female university students studying dental hygienics at a local district in Jeollanam-do. Collected data was analyzed by Chi-square test, t-test, one way ANOVA, Scheffe multiple range test, Perason's correlation test, and stepwise multiple regression test. Results : 1. Smoking condition of study subjects on general characteristics showed 17.1%, where 14.0% of previous smoking history, and 68.9% of currently nonsmoker. 2. Analysis on the knowledge related to smoking and oral hygiene, awareness of anti-smoking policy, and self esteem on the general characteristics of study subjects have shown better awareness of anti-smoking policy in non-alcoholics. Significant difference was found in knowledge about smoking and awareness of anti-smoking policy according to current resident status, but no difference found in self-esteem. Higher academic grade was related to higher awareness of anti-smoking policy and better ics. aalcell. Better health, but no diffeoral hygiene were related to better awareness of anti-smoking policy, and bewhich were statistically significant. Favorable interpersonal self-estehip was related to better awareness of anti-smoking policy. 3. Analysis on knowledge regarding smoking related health and oral hygiene, awareness of anti-smoking policy, and self-esteem showed higher level of anti-smoking knowledge in non-smoking group(60.44) compared to currently smoking group or group with previous history of smoking, and better awareness of anti-smoking policy in non-smoking group(53.54) than other groups, which was statistically significant. 4. Correlation analysis among smoking related knowledge, awareness of anti-smoking policy, and self-esteem has found relatively high correlation between smoking related knowledge and awareness of anti-smoking policy, which was statistically significant(r=0.481, p<0.001). 5. Among factors influencing awareness of anti-smoking policy, higher level of smoking related knowledge and satisfaction to specialty was related to higher awareness of anti-smoking policy which was lower in current smoker than past smoker, and higher academic grade was related to higher awareness of anti-smoking policy. Conclusions : Following results emphasize the need to establish a novel curriculum by which effective programs for smoking prevention and education of anti-smoking specialist could be provided as well as promoting coaching anti-smoking activity.
