This study was performed to evaluate the quality of nutrient intakes of the hemodialysis patients (26 men and 23 women) according to the socioeconomic status by 3-day dietary recall in Daejeon city and Chungnam area, Korea. Mean age of the subjects was 50.7 yrs and BMI was 22.0 $\pm$ 0.4 kg/$m^2$. Education level was divided into two groups ($\leq$ 9 years： LE group, 9 years： HE group), and monthly family income level was divided into three groups (< 500,000 won: LI group, 500,000-1,499,999 won: MI group, $\geq$ 1,500,000 won : HI group). The data were analyzed by Student t-test and Oneway ANOVA using SPSS 9.0 version at p < 0.05 level. Intakes of energy, carbohydrates, cholesterol, potassium, thiamin and riboflavin were significantly higher in HE group than in LE group (p < 0.05). Intakes of all the nutrients except protein and phosphorus were less than Korean RDA, and INQs (Index of Nutritional Quality) of most nutrients were lower than 1.0 but cholesterol, phosphorus. thiamin and niacin being over 1.0 in HE group. MAR (Mean adequacy ratio) of all the nutrients (e.g., energy, protein, calcium, phosphorus, iron, vitamin A, vitamin C, thiamin, riboflavin and niacin) was significantly higher in HE group (0.61 $\pm$ 0.04) than in LE group (0.48 $\pm$ 0.03) at p = 0.036. Intakes of energy, protein (total, animal and plant), fat, cholesterol, potassium, calcium, phosphorus, iron, vitamin A, thiamin and riboflavin were also significantly higher in HI group than in LI and MI group (p < 0.05). Daily intakes of most nutrients were less than Korean RDA except protein ed phosphorus in HI poop, and INQs of thiamin, niacin and phosphorus were higher than 1.0, while those of calcium, iron, vitamin A and riboflavin were lower than 1.0. MAR of energy and 9 nutrients was significantly higher in HI group (0.70 $\pm$ 0.04) than in LI group (0. 56 0.04) and MI poop (0.47 $\pm$ 0.03) at p = 0.000. In conclusion, quality of nutrient intakes, especially energy and protein, was significantly influenced by socioeconomic status such as education and monthly income (p < 0.05). This result suggests that it would be very helpful to develop nutritional education programs considering hemodialysis patients' education levels, and to improve public supports (e.g., medical insurance system, low-rate lease system of dialysis equipments, etc.) focusing on the patients' family income levels f3r their better nutrition and health.

The purpose of this study was to evaluate in vitro effects of the loss of tooth substance and root surface changes following root planing with various periodontal instruments. The 39 extracted human teeth due to severe periodontal disease were included. The total 50 root surfaces of 30 teeth were root planed with following instruments : Group 1, with Gracey curette, Group 2, with ultrasonic scaler, Group 3, with rotating root planing bur, Group 4, with Gracey curette plus rubber cup polishing, and Group 5, with ultrasonic scaler plus rubber cup polishing. Following root planing, the amount of tooth substance loss was evaluated by measuring the weight of the removed tooth substance and then 5 specimens ($5{\times}5{\times}2mm$) were randomly selected from the each group for roughness measurement. Root planed areas of each specimen were subjected to five measurements using the Profilometer and an average surface roughness values(Ra) for each group was obtained. Statistical difference for roughness values of each group was analyzed using oneway ANOVA and student t-test. For scanning electron microscopic(SEM) examination of root surface changes following root planing, 15 root surfaces of remaining 9 teeth were root planed and 3 specimens were randomly selected. The mean loss of tooth substance removed was Group 1, $7.0{\pm}1.09mg$, Group 2, $1.3{\pm}1.00mg$, Group 3, $5.8{\pm}1.72mg$, Group 4, $8.7{\pm}1.34mg$, and Group 5, $4.5{\pm}1.68mg$ following root palning, respectively. These results indicate that curette is effective instrument in the respect of diseased root substance removal. The average surface roughness values are following results : Group 1 and Group 4 were the smoothest surface ($Ra=0.34{\pm}0.06{\mu}m$, $Ra=0.34{\pm}0.04{\mu}m$, respectively) and Group 2 was the roughest surface ($Ra=2.09{\pm}0.06{\mu}m$). Statistical analysis of roughness values demonstrated a highly significant difference (P<0.05) between each experimental groups. However, no statistically significant difference in roughness values were observed between the Group 1 and Group 4. The results in this study suggest that curette and/or polishing procedure should be done after root planing with ultrasonic scaler and caution should be used with dia-mond-coated bur during routine root planing procedure.

The purpose of this comparative study is to find out women and their spouses' sexual life and the factors affecting on their sexual life after women's hysterectomy. The data were the 110 questionaires which were collected from the participants, the 55 women who had undergone a hysterectomy due to gynecologic disease or benign tumor of genital organs and their spouses from January 1, 1999 to January 30, 2002 in one general hospital located in Seoul, Korea. Questionnaires were mailed to couples, who agreed to participate on the study and self reported questionnaires returned in the pre-stamped envelopes. And personal visits were made for those couples who did not respond. Tools for Sexual life and characteristics of sexual activities were reconstituted by the author based on Kim(1996) and Chang(1988)'s tools and were reviewed by a nurse specialist. Data analysis was done by SPSS 10.0 program using frequency, percentage, mean, S.D. Pearson correlation coefficient, t-test, oneway ANOVA and multiple regression. The results of this study are as follows; 1. Of all female subjects, 80% had experienced hysterectomy below the age of 50. 2. 72.8% of female subjects and 67.3% of male subjects did not receive any sexual education & counseling before and after the surgery. More than 60% of both female and male subjects answered that it was necessary to have a sexual counseling. And 40% wanted to receive sexual counseling from a professional sexual counselor. 3. More than half of couples started their first coitus within 4 weeks after the surgery. And 88.9% of females and 85.2% of males answered that they were experiencing orgasms with their sexual relationship. 4. Influencing factors on the satisfaction level of sexual life were couple's intimacy and sexual discomfort in women and couple's intimacy and sexual knowledge in spouses. These factors explained the 33% and 24% of total variance respectively. In conclusion, the result suggests that it is necessary for couples to receive a professional sexual education and counseling to improve couples' quality of life. It is also necessary for institutions to use prepared nurses by receiving sexual counseling and education program as a professional sexual counselors or educators so as to provide individualized sexual education and counseling for their clients.

Background: The aim of this work was the comparison between the carcass and the meat ewes of the regional Traditional market and the Islamic religious (Halal) market. Methods: Thirty and 20 at the end of career traditional market and Halal market ewes were slaughtered following the EC (European Council, 2009) animal welfare guidelines. Live weight of ewes was taken and dressing percentage of carcasses was calculated. On every carcass zoometric measurement and the evaluation trough the EU grid rules were performed. On the Musculus longissimus thoracis of 12 Traditional market carcasses and 11 Halal market carcasses the physical-chemical and nutritional analysis were performed. Consumer tests for liking meat ewe were performed in order to find consumer's preference level for Traditional and Halal markets ewe meat. Considering as fixed factor the ewe meat market (Traditional and Halal), results were submitted to oneway Analysis of Variance (ANOVA) and to Principal Component Analysis (PCA). Results: The Halal market ewes have shown lower dressing percentages ($42.91{\pm}0.82$ vs $46.42{\pm}0.69$) and lower conformation score ($4.5{\pm}0.5$ vs $7.8{\pm}0.4$). The Halal market meat showed higher cooking loss in oven ($37.83{\pm}1.20$ vs $32.03{\pm}1.15%$), lesser Chroma value ($18.63{\pm}0.70$ vs $21.84{\pm}0.67$), and lesser Hue angle value ($0.26{\pm}0.02$ vs $0.34{\pm}0.02$). This product had also lower fat percentage ($4.2{\pm}0.4$ vs $7.09{\pm}0.4$). The traditional market meat had higher percentage in monounsatured fatty acids (MUFA) ($43.84{\pm}1.05$ vs $38.22{\pm}1.10$), while the Halal market meat had higher percentage in ${\omega}3$ poliunsatured fatty acids (PUFA) ($5.04{\pm}0.42$ vs $3.60{\pm}0.40$). The consumer test showed as the ewe meat was appreciate by the consumers. Conclusions: Both meat typologies have shown good nutritional characteristics. The traditional market meat had higher MUFA composition, and a better MUFA/satured fatty acids (SFA) ratio, while the Halal market meat had higher PUFA composition. These results were also supported by the PCA. The consumers preferred the traditional market meat.

Purpose: The purpose of this study is to know the blood stasis pattern for the patients who had hysterectomy. Methods: Among the patients who had hysterectomy in the department of obstetrics and gynecology, OO medical center from March 3rd 2009 to October 21st 2009, subjects who met inclusion criteria and submitted appropriate questionnaire. We compared blood stasis score and operational method, age, BMI, past operation history of abdominal and pelvic site, parity, whether adhesiolysis, oriental medicine intervention was done. For statistics, we used independent samples t-test, oneway analysis of variances(ANOVA) and SPSS version 13.0 for windows. Results: Blood stasis score of the subtotal hysterectomy group ($44.43{\pm}15.01$) is higher than that of the total hysterectomy group($39.04{\pm}12.46$). Blood stasis score under the age 40($51.88{\pm}12.68$) is higher than 40-49 age patients($40.34{\pm}14.24$) and over the age 50 patients($41.62{\pm}13.46$). There is no statistically significant difference between laparoscopic and abdominal trial, whether adhesiolysis, oriental medicine intervention was done, BMI, past operation history abdominal and pelvic site, parity, chief complaint before hysterectomy, oriental medicine intervention. Conclusion: Through the results showed, when traditional Korean medical doctors use static blood medication, history of hysterectomy and age should be considered as the history of subtotal hysterectomy and younger age tend to have a higher rate of a blood stasis pattern. We need a further study to develop blood stasis indicators with a validated questionnaire, and more subjects involved at multiple institutions.

The purposes of this study are to delineate a profile of the state of a stroke patient's adaptation at 3 months after hospitalization and to explore the relationship between the level of adaptation and the variables which influence the adaptation of hemiplegic patients. To these ends, theoretical framework was derived basically from the stress adaptation model. The basic assumption underlying the level of adaptation is influenced by the presenting focal, contextual and residual stimuli. This group of stimuli is further operationalized and represented by a perception of stress. which is the perceived effect of the disability and by the mediating variables such as sociodemographic factors as an external conditioning variables and perceived social support and hardiness personality characteristics as an internal intervening variables. The dependent varibales in this study is the level of physical, psychological and social adaptation and is hypothesized to be a function of the interaction between 3 sets of variables namely, the perceived disability effect, external conditioning variables and internal intevening varibles. A total of fourty three subjects from 3 general hospitals in Seoul were observed and interviewed with the aid of 7 structured instruments. The data were collected twice on each subject : first at the pre-discharge period arid at 3 months post-discharge from hospital for the second time. The study was carried out for the period from February to August, 1988. The instruments used for the study include 4 existing scales and 3 scales developed by the researcher for this study. They are : 1) The ADL dependency scale and the scale of the clinical physical functions for the assessment of physical adaptation. 2) the SDS(self report of depression) to measure the level of psychological adaptation. 3) The scale for the amount of social activities for the measurement of the level of social adaptation. 4) The scale for the perceived effect of disability for the measurement of the focal stimuli. 5) The health related hardiness scale and the perceived interpersonal support self evaluation list(ISEL) for the measurement of the hardiness personality character and the perceived social support. The data obtained were analyzed using percentage, oneway ANOVA, Pearson coefficients correlation and stepwise multiple regression. The findings provide valuable information about the present level of physical adaptation at 3 months after discharge. The patient revealed a decreased ADL dependency and lowered limitation of physical function as compared with pre - discharge state. Psycholcgically, the average degree of depression at follow up was within normal range of depression. Socially, the amount of social activities was very low. The one way ANOVA and the correlational analysis revealed the relationship between the 3 sets of variables and the adaptation level as follows : 1) The perceived disability effect was related to the degree of the depression and the amount of social activities but was not related to the physical adaptation. 2) Among the sociodemographic variables, sex and education were related to the difference of ADL dependency and the change of physical function. These factors indicate that women more than men and educated more than the less educated were found more independent. The education was also related to the degree of depression suggesting that the higher the educational level, the more well adapted the patients were both physically and psychologically. Age, marital status and job state were not found to be related to the patient's adaptation level. 3) Among the internal intervening variables, the health related hardiness characteristic was related to the differences of ADL dependency, physical functions and the social activities, indicating that the higher the hardiness character the higher the level of physical and social adaptation. 4) The perceived social support, another internal intervening variable, was related to the degree of depression and the social activities. This data suggest that the higher the perception of social support, the better adapted the patients were psychogically and socially. In summarizing the results of the correlational analysis, the level of physical adaptation was influenced by sex, the years of education and the hardiness character. The level of psychological adaptation was influenced by the years of education, the perceived disability effect and the perceived social support. And the level of social adaptation was influenced by the perceived disability effect, the hardiness character and the perceived social support. The stepwise multiple regression analysis shows findings as follows : 1) The most important factor to explain the difference of ADL dependency was sex, indicating females were more independent than males. 2) The most important factor to explain the difference of physical function and the degree of depression was the patient's education level. 3) The strongest explaining factor for the amount of social activities was perceived self esteem(one of the subconcepts of perceived social support). Thus the most important factors influencing the level of adaptation were found to be sex, education, the hardiness character and self esteem. From the above findings, the significance of this study can be delineated as follows : 1) Corroboration of the assumed relationship between the various variables and the adaptation level as suggested in the conceptual model. 2) Support for the feasibility of the cognitive approach for nursing intervention such as hardness character training, counselling and teaching for self-care in the chronic patients.

본 연구의 목적은 제7차 교육과정에서 초, 중, 고등학교 실과(기술 가정) 담당 교사가 인식하고 있는 의생활 교육의 실태와 실과(기술 가정) 교과서의 의생활 교육내용의 적정성을 알아보는 데 있다. 연구 자료는 전국에서 초등학교, 중학교. 고등학교 실과 및 기술 가정교과의 의생활 영역을 지도하고 있는 교사를 대상으로 우편을 통한 설문지로 수집하였으며, 203 3부를 최종 분석에 사용하였다. 자료는 SPSS/WIN 12.0 프로그램을 이용하여 평균. 표준편차, 백분율. t-test. Oneway-ANOVA와 사후검증 Duncan을 실시하였다. 본 연구를 통해 밝혀진 결과를 요약하면 다음과 같다. 첫째, 의생활 실습실 설비 실태는 초등학교의 경우 24%이고 중학교 97%. 고등학교 78% 정도였다. '재봉틀 다루기'가 나오는 초등학교에 75%정도가 재봉틀이 없어 사용하지 못하였다. 둘째. 실과(기술 가정) 의생활 교육내용의 학습량에 대해 50%의 교사들이 적당하다고 하였으며 그 중 초등학교 교사는 '재봉틀 다루기'를, 중학교 교사는 '반바지 만들기'를. 초등학교 교사는 '식탁보와 커튼 만들기'와 '베개커버나 가방 만들기' 등 실습 내용에 대해 학습량이 많다고 인식하였다. 셋째, 실과(기술 가정)의 의생활 교육내용 내용수준에 대해 초등학교 교사들은 전체적으로 보통으로 인식하였는데. 그 중 초등학교 교사의 80%는 '재봉틀 다루기'와 '쿠션이나 방석 만들기'의 내용을 어렵다고 인식하였고, 중학교 교사는 특히 '여러가지 옷감의 종류'와 '반바지 만들기'의 내용을, 고등학교 교사는 '식탁보나 커튼 만들기' 등 실습관련 내용을 어렵다고 하였다. 넷째 실과(기술 가정) 의생활 교육내용의 중요도에 대해 초등학교 교사는 '손바느질의 기초바느질 익히기'와 '손바느질로 주머니 만들기'를 중요하다고 인식하였고 '쿠션이나 방석 만들기'의 중요도를 낮게 인식하고 있었다. 중학교 교사는 '반바지 만들기'를, 고등학교 교사는 '식탁보와 커튼 만들기'와 '베개커버나 가방 만들기'와 같이 실습을 주로 하는 교육내용의 중요도를 낮게 인식하였다. 이상과 같은 연구의 결과를 바탕으로 다음과 같이 제언을 하고자 한다. 초등학교 실과교과에서 의생활 수업을 효과적으로 하기 위해서는 실습실과 재봉틀 등 설비를 반드시 갖추어야 한다. 또한 초등학교 실과 의생활 교육내용요소 중 학습량이 많고. 내용수준이 어려우며, 중요도가 낮다고 인식한 재봉틀 사용에 관한 교육내용은 이수 학년을 이동하거나 삭제 또는 쉽게 재구성하는 방안을 고려해야 할 것이다. 실과(기술 가정) 의생활 교육내용 중 학습량, 내용수준, 중요도에 대해 부정적인 견해가 나타난 것이 주로 실습활동내용이었다. 따라서 의생활 교육내용의 적정화를 위해서는 의생활 실습활동내용을 학생의 활동을 위주로 하여 학생의 생활과 익숙한 경험을 중심으로 구성할 필요가 있다.
