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.

This study was conducted to make certain that the intramuscular fat score at 13th rib could represent the fat content of whole loin from Hanwoo in Korea beef grading system. A total 42 loins from 23 carcasses of grade $1^{{+}{+}}$, 16 carcasses of grade $1^+$, and 3 carcasses of grade 1 of Hanwoo were used for this study. The crude fat content and intramuscular fat score at the $1^{st}$, $6^{th}$, and $13^{th}$ rib, and the last lumbar position of loin were measured. The crude fat content was the highest at the $6^{th}$ rib of loin from the carcasses of grade $1^{{+}{+}}$ and $1^+$ (p<0.05). There were no significant difference of the intramuscular fat scores measured by image analysis and beef marbling score (BMS) between the 6th and $13^{th}$ rib of loin from the carcasses of $1^{{+}{+}}$ and $1^+$ and that were significantly higher than intramuscular fat scores at the $1^{st}$ rib and the last lumbar position of the loin. From the results, we conclude that the intramuscular fat score at the $13^{th}$ rib can represent the fat content of loin when meat graders decide the grade of Hanwoo carcass.

The purpose of this study is to identify the amount of social support and quality of life perceived by elderly people in rural areas and to examine the relationship between social support and quality of life in an effort to provide the basic data for effective nursing intervention to enhance quality of life among elderly people. Data were collected from a sample of 220 elderly people aged over 60 from a stratified probability method from one rural area in South Jeolla province from Aug. 15 to Sep. 15, 2002. For data collection, pre-educated researchers visited the participants' homes and surveyed them face-to-face. The statistical analysis was performed using the SAS program along with t-test, ANOVA, and Pearson Correlation. The findings were as follows: 1. The most socially supportive people they answered were Spouses (57.28%), followed by children, friends/neighbors, in descending order. In terms of satisfaction about social support, the subjects felt the most satisfaction from spouses, followed by friends/neighbors, children, in descending order. 2. The participants' perceived social support was 26.0 and the highest score was 108.0 out of 125. Also, the average score and average grade point was 81.7 and 3.35, respectively. A comparison of the average grade points per items within sub-areas of social support revealed financial aid(3.56), informative support(3.34), emotional support (3.27), and evaluation support(3.22). 3. Their perceived social support had statistically significant differences in terms of how much they earned (F=18.56, p= .00001) and whether they had family members living together (F=2.68, p= .0512), quality of life had statistically significant differences in terms of how much they earned (F=35.34, p= 0.00001). 4. The quality of life they perceived was the lowest score 47.0, the highest score 196.0, average score 145.7, and average grade points 3.28. A comparison of the average grade points per items within sub-areas of quality of life revealed neighbor relationships(3.97), self-esteem(3.49), family relationships(3.35), economic conditions 3.12), physical health (2.98), and psychological health(2.74). 5. The relationship between the amount of the subjects' social support and quality of life was significantly correlated (r=.696, p< .001). The findings revealed that social support for elderly people in rural areas was a greatly effective factor on their quality, of life. Also, it was shown that the larger the social support for the elderly, the greater the quality of life for them. Therefore, it is necessary to foster geriatric nurse specialists and develop nursing intervention programs connected with health care and social wellbeing in order to enhance the quality of life of elderly people in rural areas. Also, it is necessary to develop effective models for community and its applications, which will playa leading role for elderly people.

In this paper, we propose on objective evaluation model of telephone transmission qulity in order to estimate a satisfaction score regarding speech quality in a relephone network. As the degradantion factors of telephone transmission quality, this model takes into account transmission loss, noise, distortion, talker echo and sidetone. A performance index[PI] is introduced for five psychological factors affecting telephone speech qualty, and a Mean Opinion Score(MOS) is estimated from the sum of all Pis. The simulation results indicate theat the MOS obtained from the objective evaluation model is in good agreement with that of subjective evaluation.

This study was performed to assess diet quality in the postmenopausal women. The data of dietary intakes were obtained using food frequency questionnaires which were collected from 151 postmenopausal women in urban area. We evaluated nutrient intake and diet quality. Diet quality was assessed by NAR(nutrient adequacy ratio), FGIP(food group intake pattern), DDS(dietary diversity score), DVS(dietary variety score), FGS(food group score), DQI(diet quality index). Nutrient intakes of the subjects were close to Korean RDA. Nutrient composition of the diet(in percentage of total energy) was 64% carbohydrate, 15% protein, and 19% protein, and 19% total fat, that was close to 65 : 15 : 20. NAR of most nutrients, except vitamin A, E, were higher than 0.75 and MAR was 0.88. NAR and MAR of the subjects in theis study were higher than those of the subjects of rural area in other studies. The subjects who consumed the five food groups were 60.9%. The mean of DDS was 4.5. The subjects who consumed more than 61 dish items during a month were 61.5%. The mean of DVS was 62.4 and it was significantly higher in the elder age group. 67.6% of the subjects were below FGS of 12. The mean of FGS was 10.6 and few subjects consumed serving numbers of each food groups which were recommended for Koreans. 55.0% of the subjects were DQI scores of 0, 1, and 2. The mean of DQI was 2.3 and few subjects followed the five dietary guidelines for Korean.

Objectives. The purpose of this study was to evaluate the quality of abstracts of original articles. Methods. This subjects selected total 63 abstracts of the original articles of the Korean Journal of Preventive Medicine in 1997. The quality of abstracts was measured against a checklist of evaluation criteria, which were divided into eight categories and the numbers of inappropriate words (including grammar) according to criterionbased survey. A score for each abstract was obtained by dividing the number of criteria presented by the number applicable. The overall mean score was also determined. Results. The overall mean score of abstract quality was 0.55 out of 1. Of the abstracts subject selection 83% didn't include specific technical descriptors. Of those that gave conclusions 92% didn't address study limitations and 78% made no recommendations for future study. The overall mean number of inappropriate usage of words (including grammar) per abstract was 14.1. The overall mean number of English words was 283. In the multiple regression analyses, the research career of the first author and the number of English words to the number of inappropriate usage of words were statistically significant. Also, in the secondary regression model, the number of English words to the quality score of abstract was only statistically significant. Conclusions. Most of the abstracts provided some information pertaining to each evaluation criterion. However, they did not provide sufficient details to enhance the reader's understanding of the article. On the basis of the study the abstracts need improvement in its description of the reported subject selection, statements of limitations and recommendations, etc. The Korean Society for Preventive Medicine will recommend a proposal for more informative abstracts in Korean J Prey Med and will take into consideration the introduction of foreign review of abstracts. Future studies should address these issues and compare the quality of abstracts between different journals and their time of publication.

This study was conducted to evaluate characteristic of water duality in coastal sea of Incheon using a multivariate analysis. The analysis data in coastal sea of Incheon was aquired by the NFRDI data which was surveyed from March 1997 to November 2003. Eleven water quality parameters were determined on each survey The results were summarized as follow : Water quality in Incheon coastal sea could be explained up to 64.62% by three factors which were included in loading of fresh water and nutrients by the land(36.98%), seasonal variation(16.19%), and internal metabolism (11.24%). The results of time series analysis by factor score, in case of factor 1, station 1 influenced by Han river was shown to high factor score and station 3 located by outer sea was shown to low factor score. In case of factor 2, station 1 was appeared to high variation and station 3 was appeared to low variation. The result of cluster analysis by station was classified into three group that has different water quality characteristics. Especially, station 1 which affected by Han river and station 4 which affected by sewage treatment plant was appeared to considerable water quality characteristics against other station. In yearly cluster analysis, three group was classified and water quality in 2003 years due to high precipitation was different to another year. It could be suggested from these results that it is important to control discharge of fresh water by Han rivet and sewage treatment plant for water quality management of coastal sea of Incheon.

Background: Little is known about the effects of premenstrual syndrome (PMS) on work-related quality of life in nurses. We aimed to investigate the effect of PMS on work-related quality of life in Turkish nurses. Methods: A total of 134 volunteer nurses were included in this cross-sectional study between January 2015 and March 2015. One hundred and thirty-four nurses completed a questionnaire regarding demographic data, the Premenstrual Syndrome Scale (PMSS), and the Work-Related Quality of Life Scale (WRQoL). The nurses were classified as having or not having premenstrual syndrome according to the PMSS. Results: The average age was $29.5{\pm}7.1years$ and the prevalence of PMS was 38.1%. The total score of PMSS was significantly negatively correlated with the overall score (r = -0.341; p < 0.001) and all subscale scores of the WRQoL and ranged from -0.207 to -0.402 (p < 0.05 for all). All of the WRQoL subscale scores except stress at work (p = 0.179) in nurses with PMS were significantly lower than those of nurses without PMS (p < 0.05). The age (${\beta}=-0.258$; p = 0.021) and PMSS total score (${\beta}=-0.314$; p < 0.001) increment negatively; however, optimistic thinking (${\beta}=0.228$; p = 0.008) positively affected overall WRQoL score. Conclusion: Nurses with PMS have decreased levels of work-related quality of life in their professional lives. Methods to help cope with cyclic premenstrual symptoms may be used, and as a result, productivity and work-related quality of life may increase.

본 연구의 목적은 간호대학생의 수면의 질에 영향을 미치는 요인을 우울, 수면 전 스마트폰 사용행태 및 학업 성적을 중심으로 파악하고자 하였다. 2개 대학 3, 4학년 간호학과 학생 중 임의 표출 방식으로 선정한 대상자 196명을 대상으로 하였다. 수면의 질 도구(PSQI-K), 우울 도구(한국판 Beck의 우울척도-II), 수면 전 스마트폰 사용행태 도구를 활용하여 2021년 4월에서 7월까지 자료 수집하였고, 간호대학생의 수면의 질에 미치는 영향력은 단계적 다중회귀분석으로 분석하였다. 연구 결과 간호대학생의 수면의 질은 우울과 수면 전 스마트폰 사용행태 2개의 변수가 39.0%를 설명하고 있었으며, 통계적으로 유의하였다. 즉, 우울 수준이 높을수록, 수면 전 스마트폰 사용행태 수준이 높을수록 수면의 질 수준이 유의하게 낮았다. 그러나 성적은 간호대학생의 수면의 질에 영향을 미치는 유의한 변수는 아니었다. 결론적으로 간호대학생의 수면의 질을 향상하기 위해서는 우울과 관련된 수면 양상의 부정적인 영향을 최소화하고, 수면 전 스마트폰 사용행태를 줄이는 생활 습관 교정이 필요하다.
