  • The desire to maintain health is increasing, consequently the role of nursing which has as one chief aim the solving of man′s basic problems is more and more important. Today, in spite of a growing concern about the nursing activities which nurses provide for individual human having specific needs, clinically in fact, it is questionable that individual′s expectation of nursing activities agrees with nurse′s performance of nursing activities. In this study the importance and agreement of the importance of the nursing activities during the hospitalized puerperal period as viewed by women in the puerperal period and by nurses caring for them, were assessed. The present study was undertaken in an attempt to furnish the basic data for expediting the progress of research activities in this area and further to be helpful in planning maternity nursing practice. The study population defined and selected was nurses (13) caring for women in the puerperal period and doing duty on obstetric & gynecologic ward at Y. hospital, and the women in puerperal period (39) as sum of 3 women selected by each nurse during the period of May 13th-June 4th 1976. The study data was collected by the direct interview method based on the questionnaire which the investigator made out. The study result was analyzed by percentage, t - test. The findings can be summarized as follows: 1. General characteristics of nurses doing duty on puerperal ward: a. Nurses′average age was 24.8 years old. b. 84.6% had educational background of 4 years of college. c. 69.2% had a religion. d. 53.8% were married. e. 53.8% had clinical experience of 1 year -3 years. f, 61.5% did duty on puerperal ward during 1 year -3 years. g. 46.2% desired to do duty on obstetric ? gynecologic ward. 2. General characteristics of the women who were studied during their puerperal period: a. Women′s average age was 26.4 years old. b. 79.5% had educational background above high school. c. 56.4% had a religion. d. 84.6% had living standard above medium. e. 89.7% had no occupation. f, 53,8% had previous hospitalization experience. g. 56.4% had previous delivery experience. 3. Examining the importance of 39 nursing activities during puerperal period selected by investigator, studied group of women considered that the most important nursing activity was "Record precisely about condition, medical treatment and nursing activity results etc". Nurses considered that the most important nursing activity was "Notice whether having pain and care for that". Both groups considered that the least important nursing activity was "Talk with her about topics such as news, hobbies, other interests". 4. Examining the importance of nursing activities in 4 specific categories, studied group of women considered that the most important nursing activity in physical nursing category was "Be sure of safety measure to prevent accidents, injuries", and nurses considered that the most important nursing activity was "Make her sleep and rest sufficiently". Studied group of women considered that the most important nursing activity in psychological category was "Explain about medical treatment and nursing activity ahead of time so she knows what to expect" , and nurses considered that the most important nursing activity was "Explain about puerperal period so she understands". Studied group of women considered that the most important nursing activity in relation to medical care was "Record precisely about condition, medical treatment and nursing activity results etc.", and nurses considered that the most important nursing activity was "Observing, cleaning and protecting the perineum" Studied group of women considered that the most important nursing activity in nursing category in preparation for discharge was "Instruct about personnel hygiene during puerperal period", and nurses considered that the most important nursing activity was "Instruct self-care to protect the perineum". 5. The analysis of this study showed a significant amount of disagreement computed by subtracting the nurse′s score from the patient′s score. Studied group of women put greater importance on physical nursing category, psychological nursing category, nursing in relation to medical care, than the nurses. These results were statistically significant at 0.01 level.

  • The purposes of this study are to identify the necessity of utilization of electric thermometer, to determine the difference of clinical thermometers to reach maximum or optimum temperature, and to determine the length of time necessary for temperature taking, with Fahrenheit thermometer, electric thermometer, Yu Ⅱ centigrade thermometer, and Kuk ll centigrade thermometer. The first and second comparative Experiments were' conducted from August 25 through September 30, 1973. In the first experiment, Fahrenheit thermometer, which had been accurately teated two times, and electric thermometer have been utilized. These two kinds of thermometers were inserted simultaneously under the central area of the tongue and the mouth kept closed while thermometers were in place. All temperature readings were done at one minute interval until leaching-maximum temperature. These procedures were repeated one hundred times and the data were-analyzed statistically by means of the t-test. In the second experiment, Fahrenheit thermometer, which had been accurately tested two. times, Yu Ⅱ centigrade thermometer, and Kuk Ⅱ centigrade thermometer have been utilized. These three kinds of thermometers were inserted simultaneously under the central area of the. tongue and the mouth kept closed while thermometer were in place. All temperature readings were done at one minute interval until reaching maximum temperature. These procedures were. repeated one hundred times and the data were analyzed statistically by means of the F-ratio Under the eight hypotheses designed for this study, the findings obtained are as follows: 1. There were no significant differences in the maximum temperature between Fahrenheit thermometer and electric thermometer. The mean maximum temperature for Fahrenheit thermometers was 37.06℃ and for electric thermometer was 37.09℃. 2. The placement time to reach maximum temperature taken by Fahrenheit thermometer was significantly shorter than that by electric thermometer. The mean placement time for Fahrenheit thermometers was 4.04 minutes, for electric thermometer was 5.52 minutes. In the case of Fahrenheit thermometers, 45 to 77 percent after 3 to 5 minutes, over 90 Percent after 7 minutes, and 100 percent after 10 minutes, had reached optimum temperature. When the electric thermometer was used, 23 to 54 percent after 3 to 5 minutes, over 90 percent after 9 minutes, and 100 percent after 12 minutes, had reached optimum temperature. 5. There ware no significant differences in the maximum temperature among Fahrenheit thermometer, Yu Ⅱ centigrade thermometer, and Kuk Ⅱ centigrade thermometer. The mean maximum temperature for Fahrenheit thermometers was 36.67℃, for Yu Ⅱ centigrade thermometer, was 33.73℃, and for Kuk Ⅱ centigrade thermometers was 37.76℃. 6. There were no significant differences in placement time to reach maximum temperature among Fahrenheit thermometer, Yu Ⅱ centigrade Thermometer, and Kuk Ⅱ centigrade thermometer. The mean placement time (or Fahrenheit thermometers was 7.77 minutes, for Yu Ⅱ centigrade thermometers was 7.25 minutes, and Kuk Ⅱ centigrade thermometers was 7.25 minutes. In the case of Fahrenheit thermometers, 8 to 24 percent after 3 to 5 minutes, over 90 percent after 11 minutes, and 100 percent after 13 minutes, had reached maximum temperature. When the Yu Ⅱ centigrade thermometer was used, 10 to 27 percent after 3 to 5 minutes, over 90 percent after 11 minutes, an8 103 percent after 13 minutes, had reached maximum temperature. When the Kuk Ⅱ centigrade thermometer was used, 11 to 27 Percent after 3 to 5 minutes, over 90 percent after 11 minutes, and 100 percent after 12 minutes, had reached maximum temperature. 7. There were no significant differences in the optimum temperature(the maximum temperature minus 0.1℃) among fahrenheit thermometer, Yu Ⅱcentigrade thermometer, and Kuk Ⅱ centigrade thermometer. The mean optimum temperature for Fahrenheit thermometers was 36.60℃, for Yu Ⅱ centigrade thermometers was 36.69℃, and Kuk Ⅱ centigrade thermometers was 36.69℃. 8. There were no significant differences in placement time to reach optimum temperature among Fahrenheit thermometer, Yu Ⅱ centigrade thermometer, and Kuk Ⅱ centigrade thermometer The mean placement time for Fahrenheit thermometers was 5.70 minutes, for Yu Ⅱ centigrade thermometers was 5.54 minutes, and for Kuk Ⅱ centigrade thermometers was 5.28 minutes. In the case of Fahrenheit thermometers, 21 to 49 percent after 3 to 5 minutes, over 90 percent after 9 minutes, and 100 percent after 12 minutes, had reached optimum temperature. When the Yu Ⅱ centigrade thermometer was used, 23 to 51 percent after 3 to 5 minutes over 90 percent after 10 minutes, and 100 percent after 12 minutes, had reached optimum temperature. When the Kuk Ⅱ centigrade Thermometer was used, 23 to 57 Percent after 3 to 5 minutes, over 90 percent after 9 minutes, and 100 Precent after 11 minutes, had reached optimum temperature.

  • Much of a person's energy is spent in the effort of becoming a productive member of to-day's complex society. This activity may cause tension, and chronic unrelieved tension is an influential factor in blood pressure elevation. The problem of this study was to identify manifest needs and self-actualization of patients with essential hypertension, and to analyse and compare their manifest needs and selt-actualization with the selected general characteristics of We, sex, religion, occupation and level of education with a control group of patients with normal blood pressure readings. The purpose was to contribute to the planning of nursing interventions toward reducing the impact of complex psycho-somatic factors on the anxiety of patients with essential hypertension. The instruments used included selected items from the Edwards (1959) Personal Preference Schedule (EPPS) as adapted by Hwang (1965) and from the Personal Orientation Inventory (POI) (Shostrom 1964, 1974) adapted by Kim and Lee (1977) to measure manifest needs and self-actualization. The convenience sample was chosen from 149 persons who presented themselves for general physical examinations at Ewha University Medical Centre and 41 patients diagnosed with essential hypertension at three general hospitals in Seoul during June 1 and August 31, 1977. Forty-nine persons from the Ewha group with blood-pressure readings exceeding 150/90 were added to the experimental group. Data were analysed by the S.P.S.S. computer programme using t-test and tests for statistical significance. Statistically significant findings were as follows: A. Blood Pressure and Manifest Needs. 1. with the exception of Autonomy, patients with hypertension had significantly high scores on all variables Abasement, Achievement, Affiliation, Aggression, Dominance, Emotionality, Exhibitionism and Sex. 2. When mean scores of normal persons were compared by age groups, normal persons had higher scores in the following order on Abasement (50's, 40's, 20's, 30's), Achievement (50's, 30's, 40's, 20's), Affiliation (50's, 40's, 30's, 20's), Dominance (50's, 40's, 40's, 20's) and Exhibitionism (30's, 50's, 40's, 20's). In each case, there was a significant difference between the first and last age group scores. 3. When the mean scores of normal persons were compared by sex, normal men had higher scores than women on Achievement, Affiliation, Aggression, Dominance, Exhibitionism and Sex. Male patients had higher scores than female patients on Achievement, Dominance, Exhibitionism and Sex, but female patients scored higher in Emotionality. 4. Normal persons had higher scores related to religion in the following order on Achievement (Buddhism, no religion, Christianity). Hyper tensive patients had higher scores on. Exhibitionism (no religion, Christianity, Buddhism). 5. Normal persons had higher scores related to occupation in the following order on Achievement and Exhibitionism (unemployed, office workers, teachless, businessmen), Emotionality (office workers, unemployed, businessmen, teacher) and Sex (office workers, unemployed, teachers, businessmen). Hypertensive patients had higher scores on Achievement and Aggression (teachers, businessmen, office worker, unemployed), Dominance and Exhibitionism (businessmen, teacher, of ace workers, unemployed) and Sex (teachers, office worker, businessmen, unemployed). 6. Normal persons had higher scores related to level of edification in the following order on Abasement, Emotionality and Autonomy (secondary school graduation, university). Hypertensive patients had higher scores on Abasement (no education, primary, university, secondary), Achievement (no education, secondary, university, primary) , Dominance (university, no education, secondary, primary), Exhibitionism (university, secondary, no education, primary), and Sex (university, secondary, primary, no education). B. Blood Pressure and Self_Actualization 1, Patients with hypertension had significantly lower scores on all variables. 2. Normal persons had higher scores related to age groups in the following order on Existentiality (20's, 30's, 40's, 50's). Hypertensive patients showed no significantly different scores. 3. Normal women had higher scores than men on Time Competence. Normal men had higher scores on Feeling Reactivity. Male patients had higher scores than women on Self-Actualizing Value and Self-Regard. 4. Normal persons ha 1 higher scores related to religion on spontaneity (Buddhism, no religion, Christianity). Hypertensive patients had higher scores on Time Competence and Nature of Man (Buddhism, Christianity, no religion). 5. Normal persons had higher scores related to occupation in the following order on Existentiality (teachers, office workers, businessmen, unemployed) and Self-Regard (unemployed, office workers, teachers, businessmen). Hypertensive patients showed no significantly different scores. 6. Normal persons had higher scores related to level of education in the following order on Existentiality and Self-Acceptance (university, secondary). Hypertensive patients had higher scores on inner-Director (university, secondary, no education, primary) and Existentiality (university, secondary, primary, no education). Recommendations for nursing interventions with hypertensive patients with emotional problems or low self-actualization were made. 1. The nurse should encourage the patient through her interactions with other members of the medical team to accept counselling and health education. 2. Through her therapeutic interpersonal relationships with the patient, the nurse should help him discover the causes of his emotional tension. 3. Through her health teaching with the family, the nurse should encourage them to participate with the medical team in the patient's therapeutic plan and in providing him with the minimum possible emotional support. 4. Through frequent counselling with the obsessive-thinking and inflexible patient, the nurse should reevaluate the patient's behaviour and her interventions. 5. Seriously ill patients should be given needed reeducation by members of the professional medical team.

  • Objectives : The purposes of this study were to examine the reliability and validity of the Korean version of Social Communication Questionnaire (K-SCQ) and to determine cut-off scores for diagnosis of autism spectrum disorder (ASD). Methods : A total of 166 subjects with ASD and their 186 unaffected siblings were recruited through child psychiatry clinics of university hospitals. Board certified child psychiatrists screened all probands suspected to have ASD based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. To confirm the diagnoses, the Korean versions of the Autism Diagnostic Observation Schedule and the Autism Diagnostic Interview-Revised (K-ADI-R) were administered to all the subjects. All parents completed the K-SCQ and Social Responsiveness Scale (SRS). The non-ASD siblings were evaluated with the same instruments as the probands with ASD. We performed a factor analysis to examine the structure of K-SCQ. For testing the validity of K-SCQ, we compared the difference in Lifetime and Current scores of probands with ASD and their non-ASD siblings using t-test and analysis of covariance. Correlations between the K-SCQ and other measurements of ASD symptomatology, including K-ADI-R totals and domain scores and SRS, were examined. Receiver operation characteristic curve analysis was performed to extract cutoff scores discriminating affection status. Results : Four factors were extracted through factor analysis of K-SCQ ; 1) social relation and play, 2) stereotyped behavior, 3) social behavior, and 4) abnormal language. Cronbach's internal consistency was .95 in K-SCQ Lifetime, and .93 in K-SCQ Current. There were significant differences in total score of K-SCQ, both in Lifetime and Current between the ASD group and non-ASD siblings group (p<.05). K-SCQ scores were significantly correlated with K-ADI-R subdomain scores and SRS total scores (p<.05). The best-estimate cut-off scores of K-SCQ for diagnosis of ASD were 12 for 48 months and over, and 10 for below 47 months. Conclusion : Our findings suggest that the K-SCQ is a reliable and valid instrument for screening autistic symptoms in the Korean population. Lower cut-off scores than the original English version might be considered when using it as a screening instrument of ASD.

  • 연구배경: 주기성 사지운동장애(PLMD)는 여러 수면장애와 함께 공존하는 경우가 많으며, 특히 수면관련 호흡장애(SRBD)와의 관계는 밀접하다고 알려져 있다. PLMD는 반복적이고 상동증적인 사지의 움직임에 의하여 전기생리적인 각성을 일으키기 때문에 불면증과 주간 졸립증을 초래하므로 이에 대한 관심이 필요하다. 본 연구는 SRBD 환자에서 PLMD의 빈도를 조사하고, PLMD로 진단된 환자군의 특성을 조사함으로써, SRBD 환자에서 PLMD의 동반 이환에 대한 이해를 높이는데 있다. 대상 및 방법: 진단적인 수면다원 검사로 수면관련 호흡장애의 진단이 내려진 106명을 대상으로 이들의 수면기록을 후향적으로 조사하였다. 수면다원 검사의 기록과 판독은 표준적인 방법을 사용하였다. OSA 의 진단은 RDI가 10 이상인 경우 내렸고, UARS는 낮 동안에 심한 졸림증을 호소하고 수면다원 검사상 RDI가 5 이하이나 호흡노력의 증가에 이어서 짧은 각성이 반복되는 경우 내렸다. 수면중 주기성 사지운동장애의 진단은 주기성 사지운동지수가 5 이상일 때 내렸다. 자료처리는 SPSS/$PC^+$를 이용하였다. 곁 과: 평균연령은 49.5세였고, 성별은 남자 76명, 여자 30명이었다. 진단은 폐쇄성 무호흡증 78명, 상기도저항증후군 28명이었다. 전체 연구대상의 평균 수면효율은 76.3%, 평균 호흡장애 지수는 22.3/hr, 평균 혈중 산소포화도는 84.9%로 중등도의 수면중 호흡장애가 있음을 알 수 있다. 평균 주지성 사지운동 장애지수는 13.1/hr였으며 70% 이상의 환자들이 32/hr 이하에 분포하였고 개인차이가 많았다. 주기성 사지운동 장애지수가 5 이상으로 수면중 주기성 사지운동장애를 동반한다고 판단된 군이 47명으로 전체의 44.3%를 차지하였다. 수면중 주기성 사지운동장애를 동반하는 군과 동반하지 않는 군의 비교에서, 두 군간에 나이, 무호흡 지수, 성별, 1 단계 수면의 백분율에서 유의한 차이가 있었다. 결 론: 본 연구의 결과는 이전의 타 연구들보다 수면관련 호흡장애에서의 주기성 사지운동장애의 동반이환율이 더 높다. PLMD를 동반하는 군의 나이가 유의하게 더 많고, 여성에서의 동반율이 더 높고, 무호흡 지수(apnea index)가 유의하게 더 낮다. 수면중 주기성 사지운동장애는 수면관련 호흡장애와 함께 불면증과 주간 졸림증을 초래하고, 본 연구에서 뒷받침 하듯이 수면중 호흡장애 환자에서 흔히 함께 동반되기 때문에, 수면관련 호흡장애 환자의 진단 및 가료시 이에 대한 배려가 필요하다.

  • 연성 이장재를 의치에 적용했을 때, 의치 변연부에서 나타나는 공극에 의한 문제점을 많이 경험하게 된다. 그래서 변연 공극을 최대한 줄일 수 있는 방법을 연구하여야 하고 특히 최종 과정인 마무리와 연마시의 변연 공극의 양상에 대한 평가가 이루어져야 한다. 본 연구에서는 실리콘 계열의 연성 이장재인 $Molloplast-B^{(R)}$를 적용하였을 때, 의치와 연성 의치 이장재의 접합부에서 나타나는 공극의 양을 측정하고 연마 방법, 연마 방향이 변연 공극에 미치는 영향에 대하여 알아보고자 하였다. 마무리 방법과 연마 방법, 방향에 따라 군 분류를 하였고, 시편의 일관성과 정확성을 위해 금속 틀을 방전 가공하여 제작하였고, 제조사의 지시에 따라 총 50개의 시편을 제작하였다. 공극의 양은 120배 확대의 입체 광학 현미경상에서 가장 큰 값을 가지는 부위를 측정하였고, 모든 측정치는 통계적 분석, 평가 하였다. 실험 결과, 각 분류에 따른 공극을 비교 했을 때, $Molloplast^{(R)}$-Cutter로 마무리 한 후 pumice와 tin oxide를 순행하여 연마를 한 경우가 가장 크게 나타났고, FSQ-cross cut bur를 이용하여 마무리만 한 것이 가장 적게 나타났다. 또한 연마를 할수록 공극의 양이 증가되는 양상을 나타내었다. 방향에 따라서는 통계적 유의성은 나타나지 않았으나 레진에서 연성 이장재 방향으로 시행하였을 때가 더 적은 값을 나타내는 경향을 보였다. 이상의 결과로 보아 삭제력이 우수한 버일수록 레진과 연성 이장재의 접합부에서 나타나는 공극이 커짐을 알 수 있었고, 또한 연마를 시행 할수록 공극의 양이 유의성 있는 차이를 나타내었다. 접합부에서의 공극을 줄일 수 있는 마무리와 연마 방법에 대한 더 많은 연구가 이루어져야 하고 부가적으로 최종 연마가 끝나고 공극을 막아 줄 수 있는 재료에 대한 연구가 필요한 것으로 사료된다.

  • Objective: Our present studies were conducted to examine more effective isolating method of preantral follicles from mouse ovaries. Methods: ICR mice (3-6 weeks old) were sacrificed through cervical dislocation and their ovaries were removed and put into watch glasses containing Hams F-10 supplemented with 10% fetal bovine serum (FBS). Preantral follicles were isolated by three different methods; 1) enzymatical method and 2) mincing method, and 3) scraping method. Enzymatical method was carried out as following. Ovaries were bisected with a pair of fine 30G needles. Bisected ovaries were incubated at $37^{\circ}C$ and 5% $CO_2$ incubator in 2-well dish containing Hams F-10 supplemented with collagenase 600 lU/ml and DNAse 20 lU/ml. After 20 min., follicles were isolated by repeated pipetting. Isolated preantral follicles were collected, and the remnant of tissues was placed in incubator and previous procedure was repeated. Mincing method was carried out with a pair of fine 30G needles attached to 1 ml syringes and minced ovary. Scraping method was carried out with a pair of fine 30G needles and scratched to surface of ovary. The differences between isolating methods were analyzed using Student's t-test and Chi-square. Results were considered statistically significant when ${\rho}$ value was less than 0.05. Results: In handling time, mincing or scraping method ($28{\pm}3.42$ min or $16{\pm}1.58$ min) were significantly (p<0.00001) shorter than enzymatical method ($72{\pm}1.69$ min), and scraping method was significantly (p<0.01) shorter than mincing method. Total number of isolated follicles was significantly (p<0.0001) higher in enzymatical method ($49.8{\pm}3.91$) than in mincing or scraping method ($25.3{\pm}2.33$ or $20.5{\pm}1.75$). Isolated follicles in ${\leq}$90${\mu}m$ were significantly (p<0.005) higher in enzymatical method ($15{\pm}1.71$) than in mincing or scraping method ($7.8{\pm}0.98$ or $8.1{\pm}1.31$). In 91~130 ${\mu}m$, isolated follicles were significantly (p<0.0005) higher in enzymatical method ($33{\pm}3.27$) than in mincing or scraping method ($16.3{\pm}1.82$ or $10.7{\pm}1.38$). In ${\geq}$ 131 ${\mu}m$, isolated follicles were not significantly differences between all groups. In equal sizes, the rate of isolated follicles in ${\leq}$ 90 ${\mu}m$ was highest in scraping method (39.6% vs. enzymatical method: 30.1%, p<0.05; mincing method: 30.9%, p=0.11719, NS). Rate of follicles in $91{\sim}130$ ${\mu}m$ was significantly (p<0.05) lower in scraping method (52.7%) than in enzymatical or mincing method (66.3% or 64.5%). Rate of follicles in ${\geq}$131 ${\mu}m$ was highest in scraping method (8.3% vs. enzymatical or scraping method: 3.6%, p<0.05 or 4.6%, p=0.19053, NS). Conclusions: This study suggests that scraping method is simple and useful for isolation of preantral follicles, because this method reduced handling time and recovered enough follicles. The recovered rate of isolated follicles in diameter of 91 ~ 130 ${\mu}m$ was highest in all methods.

  • This study was conducted to compare the characteristics of high performane areas for family planning with that of low performance areas and to find factors which strongly affected contraceptive practice behavior. For the study, eight areas were selected from 274 rural family planning canvassing areas of Korean Population Policy and Program Evaluation Study, which was an action study operated in all areas of Cheju Island from July 1, 1976 until December 31,1979. As a first step of the action study, Cheju Island was devided up 318 family planning canvasser areas Each area was consisted of 200 households in rural district and 300 households in urhan one Duriog the period of project, each canvassing area had been managed by a female family planning canvasser, selected by director of health center considering several individual conditions needed for family planning activities Basic activities of canvassers were to counsell all the eligihie couples in own charged area about family planning methods and also to distribute contraceptives such as condoms and oral pills. In case couples desire to accept sterilization including vasectomy and tubal-ligation, the canvassers played a linking role connecting potential client with family planning field workers. Canvassng areas shows significant differentce in performance for family planning, nevertheless they are supposed to have almost the same conditions regarding family planning distribution channel. Because the purpose of the Cheju project was to eliminate all the problems that existed in governmental distribution system, that is to remove geographic, economic, cognitive and administrative barriers Accumulated performances of family planning methods accepted by residents in each area were calculated by eligible women aged 14-49. And then canvassing areas were ranked according to performance score. Consequently, 4 areas in extremely high and low family planning performance areas were selected respectively. Major results were obtained by comparing characteristics of high performance area with that of low performance areas, which are as follows: 1. The mean number of living children was about the same both in high and low performance areas for family planning. But respondents' mean age (38.5) in high performance areas was higher than that (37.0) in low performance areas 2. Respondents' perception in the expectant educational level of others' children in high performance areas was higher than that in low performance areas, although respondents educational level, monthly expenditure and ratio of children in high school and above was not different. 3. Ratio of ownerships of TV and newspaper in high performance areas was highen than that in low performance areas 4. The duration of canvasser' charge in high performance areas was longer than that of low performance areas, showing the fact that canvassers didn't move cut in high performance areas 5. In high performance areas, canvassers' houses were relatively located in the center part of the village. And so villagers resided in near distances from the anvasser's house 6. 4H clubs' activities in high performance areas were more active than those in low performance areas Therefore it was assumed that cohesiveness of community in high performance areas were stronger than that in low areas. 7. Canvassers' family planning practice rate was higher than that in low performance areas, and also canvassers' human relationship was more sociable than that of canvassers in low performance areas. 8. Fourteen variables which showed relatively high significance level in $X^2$ and F test were selected as independent variables for stepwise regression analysis. According to the results of regression analysis. five of 14 variables-distributors education level ($R^2$=.4439), duration of distributor's charge ($R^2$=.6166), 4H club activities ($R^2$=.6697), canvasser's contraceptive practice ($R^2$=.7377) and location of distributions house ($R^2$=.8010) explained 80.1 percent of total variance.
