연구배경 : Diffuse panbronchiolitis(DPB)는 1966년 일본에서 처음 기술된 만성 염증성 호흡기질환으로 기관지천식, 폐기종, 만성기관지염, 기관지확장증, 또는 폐포염과는 구별되는 질환이며 주로 일본에 많이 보고되었고, 중국 및 서구의 몇나라에서 증례보고가 있었으며, 본 교실에서도 최근 한국인에서의 DPB 환자의 임상적특징을 보고한 바 있다. DPB는 과거에 대증요법과 steroid 치료이외에 특별한 치료법이 없어 호흡부전으로 진행하여 사망하는 아주 예후가 좋지 않은 질환으로 알려졌었으나, 최근에 erythromycin의 소량장기투여가 효과가 있다는 보고가 나오고 있다. 본 교실에서는 1989년 9월부터 1993년 8월까지 서울대학교병원에서 병리학적 또는 임상적으로 DPB로 진단받은 환자 19명 중 erythromycin으로 치료하면서 6개월 이상 추적하고 있는 14명의 환자를 대상으로 erythromycin의 소량장기투여 효과를 분석하여 보고하고자 한다. 방법 : Erythromycin을 250 mg b.i.d.로 투여하고 치료전, 치료 3개월, 6개월 및 12개월 후에 환자의 자각증상, 흉부청진소견, 폐기능검사, 흉부X선검사의 변화를 관찰하였다. 결과: 1) 평균 치료 및 추적기간은 $16.4{\pm}6.5$개월이었으며 14명 전원의 환자가 erythromycin 투여 2~3개월 이내에 자각적증상(호흡곤란, 객담배출)의 호전을 보였고 1년 후 54.5%의 환자에서는 완전히 증상이 소실되었다. 2) 흉부청진상 14명 전원의 환자에서 수포음 또는 천명음의 감소가 있었고 1년 후 63.6%의 환자에서는 완전히 소실되었다. 3) FVC 및 $FEV_1$은 치료 3개월간 현저히 증가하며 이후 치료 1년까지 서서히 증가하여 거의 정상수준으로 회복되었다. 그러나 $FEV_1/FVC$는 큰 변화가 없었고 치료 1년 후 약간 증가하였다. 4) 흉부 X-선상 14명 전원의 환자에서 결절성병변의 감소가 관찰되었으나, 기관지확장증의 소견은 큰 변화가 없었다. 1년 후 36.4%의 환자에서는 정상 흉부X-선 소견을 보였다. 5) 1명의 환자가 14개월 치료후 소화장애로 erythromycin의 투여를 중단하였으나, 현재 1년 후까지 추적검사상 재발의 증거는 없었다. 1명의 환자는 16개월 치료 후 증상이 없어서 투약을 중단하였으나 1개월 후 다시 증상이 악화하여 다시 치료를 시작하여 호전되었다. 결론 : 이상의 결과로 erythromycin의 소량장기투여는 DPB환자의 치료에 괄목할 만한 효과를 보임을 알 수 있으며, 투여기간에 대해서는 향후 연구가 필요하리라 생각된다.

To evaluate the present status of physical fittness of Korean long distance runners, body fat, pulmonary functions, maximal oxygen intake and oxygen debt were measured in 5 elite marathoners (A group), 6 college student runners (B group) and 3 middle school student runners (C group). After laboratory tests, full course marathon running was performed in 2 elite marathoners during which their heart rates were monitored continuously. The results are summerized as follows: 1) Total body fat in all three groups are in the range of 13-15% of their body weight. 2) In all three groups, average values of various pulmonary functions were within the normal limits, but those of tidal volume were higher and respiratory rate were lower in comparison to normal values. These phenomena may represent respiratory adaptations against training. The average resting oxygen consumptions in A,B and C were $322{\pm}23$, $278{\pm}14$ and $287{\pm}16$m1/min, respectively. 3) In all three groups, resting blood pressures were in the normal range, but the resting heart rate was slightly lower in groups A $(56{\pm}3\;beats/min)$ and B $(64{\pm}2\;beats/min)$ and higher in group C $(82{\pm}9\;beats/min)$ in comparison to normal values. These changes in cardiovascular functions in marathoners may also represent adaptive phenomena. 4) During treadmill running the minute ventilation and oxygen consumption of the runners increased lineally with work load in all three groups. When the oxygen consumption was related to heart rate, it appeared to be a exponential function of the heart rate in all three groups. 5) The average maximal heart rates during maximal work were $196{\pm}3$, $191{\pm}3$ and $196{\pm}5\;beats/min$ for groups A,B and C, respectively. Maximal oxygen intakes were $84.2{\pm}3.3\;ml/min/kg$ in group A, $65.2{\pm}1.1\;ml/min/kg$ in group B and $58.7{\pm}0.4\;ml/min/kg$ in group C. 6) In all three groups, oxygen debts and the rates of recovery of heart rate after treadmill running were lower than those of long ditsance runners reported previously. 7) The 40 km running time in 2 elite marathoners was recorded to be $2^{\circ}42'25'$, and their mean speed was 243 m/min (ranged 218 to 274 m/min). The heart rate appeared to increase lineally with running speed, and the total energy expenditure during 40 km running was approximately 1360.2 Calories. From these it can be speculated that if their heart rates were maintained at 166 beats/min during the full course of marathon running, their records would be arround $2^{\circ}15'$. Based on these results, we may suspect that a successful long distance running is, in part, dependent on the economical utilization of one's aerobic capacity.

The purpose of this study was to provide basic data for developing nursing intervention for middle-aged women. This study identified health status, family functionality and spousal relationship and analyzed relationship between individual characteristics and family functionality/ spousal relationship. The subjects, of this study were 1.723 women from 45 to 55 years of age, who lived in J city. Data were analyzed using percentages, means, t-tests, ANOVA and Pearson's correlation coefficients with the SPSS statistical program. The results of the study were as follow: 1. The rate of women who perceived themselves to be healthy was 36.6%, those who did not was 30.8%. The most frequent health problem was a disease of the skeletal system (13.2%). 2. The mean score of family functionality was $3.25{\pm}.60$, with cohesion score of $3.58{\pm}.66$ and adaptability score of $2.99{\pm}.63$. 3. The mean score of total spousal relationship was $3.22{\pm}.42$; the relationship with in-laws was 3.78; sexual relationship, 3.74; life style, 3.44; and recreational activity. 3.39. 4. The women who experienced menopause perceived themselves to be unhealthier than those who did not. 5. Healthy women had a high score at total spousal relationship. personality of spouse. life style, recreational activity, and children's influence. 6. The women from 40 to 50 years of age. and women who graduated from middle or high school and had medium economic status showed a high score in family functionality. There was no correlation between family functionality and experience of the menopause. 7. Lower aged women were not good in personality of spouse (p<.05), sexual relationship (p<.05), and relationship with relatives (p<.05), Inexperienced women's menopause was influenced by their children (p<.05), Women who graduated from middle or high school (p<.001) and had medium economic status (p<.05) showed a high score in spousal relationship. 8. The higher the family functionality score. the higher spousal relationship. score (p<.001): love and communication (p<.001), personality of husband (p<.05), and religion (p<.001). relationship with relatives (p<.05), but the lower the score of recreational activity (p<.05), and share of role (p<.001) in the spousal relationship. 9. In the family functionality, the higher the cohesion score. the higher was the adaptability score (p<.001). l) The higher the cohesion score, the higher were love and communication, personality of husband. life style. sexual relationship. and children's influence, but the lower were share of role in spousal relationship(p<.001). 2) The higher the adaptability score, the higher were love and communication, religion, but the lower were the personality of husband, life style. sexual relationship, recreational activity, relationship with relatives, share of role(p<.001), and children's influence in spousal relationship (p<.05). 10. Variables within the spousal relationship have relationships with other variables. 1) The higher the love and communication score. the higher personality of husband religion, life style, communication. relationship with relatives, and children s influence (p<.001). 2) The higher personality of husband life style sexual relationship. recreational activity, relationship with relatives, share of role, and children's influence (p<.001). 3) The higher the religion score, the lower the recreational activity score (p<.05). 4) The higher the life style, the higher were the sexual relationship, recreational activity. relationship with relatives. share of role, and children's influence (p<.001). 5) The higher the sexual relationship score. the higher were recreational activity. relationship with relatives, share of role. and children's influence (p<.001). 6) The higher the recreational activity, the relationship with relatives, share of role. and children's influence (p<.001). 7) The higher the relationship with relatives, the higher were the share of role. the higher children's influence (p<.001). In conclusion. the spousal relationship was not good in unhealthy women, and the family functionality was related with the age of women and educational level. Also the spousal relationship was related with the age of women, personality of husband, sexual relationship. relationship with relatives by marriage and influence of sons and daughters. Menopause was related with spousal relationship, not related with family functionality. And the family functionality not related with perceived health status. but was correlated with spousal relationship. Therefore, the health management program for middle-aged woman should take place before menopause and must be based on promoting the family functionality and spousal relationship as well as physical health.

연구배경: 최대운동부하 검사는 심폐기능의 종합적인 평가를 위하여 널리 이용되고 있으나 아직 우리나라에는 최대운동시의 호흡성 가스교환이나 폐기능의 정상치가 제대로 확립되어 있지 않은 설정이다. 본 연구의 목적은 한국성인에서 최대운동시의 이들 지표의 연령과 성별에 따른 정상치 내지 참고치를 마련하는 동시에 이들 중 일부지표의 추정정상치를 산출하는 회귀방정식을 구하는데 있다. 방법: 건강한 성인 남성 603명, 여성 397명, 합계 1,000명(20~66세)을 대상으로 Bruce법으로 증상제한성 최대운동부하 검사를 실시하였으며, 이중 885명에서는 VC, $FEV_1$ 및 MVV도 측정하였다 대상자들은 모두 전문체육인이 아닌 스포츠센터의 회원이었으며, 운동부하검사 중에는 안전상의 문제 때문에 부득이 트레드밀의 손잡이를 잡는 것을 허용하였다. 곁과: $VO_2\;max/m^2$, $VCO_2\;max/m^2$ 및 VE max/$m^2$는 모두 남성에서 뚜렷이 컸으며, 남녀에서 모두 연령의 증가에 따라 감소하였다. 한편 RR max는 성별에 따른 차이는 없었으나, 연령의 증가에 따라 약간씩 감소하였으며, $V_T$ max는 남성에서 월등히 많았으나 남녀에서 다같이 연령에 따른 일정한 경향의 변화는 없었다. 그리고 $V_T$ max/VC, $V_E$ max/MVV 및 BR의 평균은 최대운동시에 나이가 많은 여성에서도 상당한 환기예비가 있음을 보여주었다. 저자들은 성적을 토대로 운동시간(분), 나이(세), 시장(cm), 체중(kg), 성별(남=0, 여=1), VC(L), $FEV_1$(L) 및 VE max(L) 등을 변수로 해서 구한 주요 지표들의 회귀방정식은 다음과 같다. $VO_2\;max/m^2(L/min)=1.449+0.073{\times}$운동시간-$0.007{\times}$연령+$0.010{\times}$체중-$0.006{\times}$신장-$0.209{\times}$성별, $VCO_2\;max/m^2(L/min)=1.672+0.063{\times}$운동시간-$0.008{\times}$연령+$0.010{\times}$체중-$0.005{\times}$신장-$0.319{\times}$성별, $V_E\;max/m^2(L/min)=58.161+1.503{\times}$운동시간-$0.315{\times}$연령-$9.871{\times}$성별 또는 $V_E\;max/m^2(L/min)=47.873+6.458{\times}FEV_1-5.715{\times}$성별 및 $V_T\;max(L)=1.497+0.223{\times}VC-0.493{\times}$성별. 결론: 본 연구에서 얻은 최대운동시의 호흡성 가스 교환 및 환기기능에 관한 성적은 건강과 체력에 대해서 일반인보다 관심이 높을 것으로 생각되는 스포츠센터 회원들을 대상으로 한 것이기 때문에, 안전상의 문제로 트레드밀의 손잡이를 잡고 검사를 해야하는 환자나 건강인을 위한 이상적인 목표치 내지 정상치를 제공한 것으로 생각된다. Background: Although graded exercise stress tests are widely used for the evaluation of cardiorespiratory performance, normal standards on respiratory gas exchange and ventilatory functions at maximal exercise in Koreans have not been well established. The purpose of this study is to provide reference values on these by sex and age, along with derivation of some of their prediction equations. Method: Symptom-limited maximal exercise test was carried out by Bruce protocol in 1,000 healthy adults consisting of 603 males and 397 females, aged 20~66 years. Among them VC, $FEV_1$ and MVV were also determined in 885 cases. All the subjects were members of a health center, excluding athletes. During the exercise, subjects were allowed to hold on to front hand rail of the treadmill for safety purpose. Results: The $VO_2\;max/m^2$, $VCO_2\;max/m^2$ and $V_E\;max/m^2$ were greater in males than in females and decreased with age. The RR max in men and women was similar but decreased slightly with age. The $V_T$ max was markedly greater in men but showed no significant changes with age in either gender. The mean of $V_T$ max/VC, $V_E$ max/MVV and BR revealed that there were considerable ventilatory reserves at maximal exercise even in older females. The regression equations of the cardinal parameters obtained using exercise time(ET, min), age(A, yr), height(Ht, cm), weight(W, kg), sex(S, 0=male; 1=female), VC(L), $FEV_1$(L) and $V_E$ max(L) as variables are as follows: $VO_2\;max/m^2$(L/min)=1.449+0.073 ET-0.007A+0.010W-0.006Ht-0.209S, $VCO_2\;max/m^2$(L/min)=1.672+0.063ET-0.008A+0.010W-0.005Ht-0.319S, VE max/$m^2$(L/min)=58.161+1.503ET-0.315A-9.871S or VE max/$m^2$(L/min)=47.873+6.548 $FEV_1$-5.715 S, and VT max(L)=1.497+0.223VC-0.493S. Conclusion: Respiratory gas exchange and ventilatory variables at maximal exercise were studied in 1,000 non-athletes by Bruce protocol. During exercise, the subjects were allowed to hold on to hand rail of the treadmill for safety purpose. We feel that our results would provide ideal target values for patients and healthy individuals to be achieved, since our study subjects were members of a health center whose physical fitness levels were presumably higher than ordinary population.

Nursing of today has as one of its objectives the solving of problems related to human needs arising from the demands of a rapidly changing society. This nursing objective, I believe, can he attained by the appropriate application of scientific principles in the giving of comprehensive nursing care. Comprehensive nursing care may be defined as nursing care which meets all of the patient's needs. the needs of patients are said to fall into five broad categories: physical needs, psychological needs, environmental needs, socio-economic needs, and teaching needs. Most people who become ill have adjustment problems related to their new situation. Because patient teaching is one of the most important functions of professional nursing, the success of this teaching may be used as a gauge for evaluating comprehensive nursing care. This represents a challenge foe the future. A questionnaire consisting of 67 items was distributed to 200 professional nurses working ill direct patient care at Yonsei University Medical Center in Seoul, Korea. 160 (80,0%) nurses of the total sample returned completed questionnaires 81 (50.6%) nurses were graduates of 3 fear diploma courser 79 (49.4%) nurses were graduates of 4 year collegiate nursing schools in Korea 141 (88,1%) nurses had under 5 years of clinical experience in a medical center, while 19 (11.9%) nurses had more than 5years of clinical experience. Three hypotheses were tested: 1. “Nurses had high levels of concept and knowledge toward patient teaching”-This was demonstrated by the use of a statistical method, the mean average. 2. “Nurses graduating from collegiate programs and diploma school programs of nursing show differences in concepts and knowledge toward patient teaching”-This was demonstrated by a statistical method, the mean average, although the results showed little difference between the two groups. 3. “Nurses having different amounts of clinical experience showed differences in concepts and knowledge toward patient teaching”-This was demonstrated by the use of a statistical method, the mean average. 2. “Nurses graduating from collegiate programs and diploma school programs of nursing show differences in concepts and knowledge toward patient teaching”-This was demonstrated by a statistical method, the mean average, although the results showed little difference between the two groups. 3. “Nurses having different amounts of clinical experience showed differences in concepts and knowledge toward patient teaching”-This was demonstrated by the use of the T-test. Conclusions of this study are as follow: Before attempting the explanation, of the results, the questionnaire will he explained. The questionnaire contained 67 questions divided into 9 sections. These sections were: concept, content, time, prior preparation, method, purpose, condition, evaluation, and recommendations for patient teaching. 1. The nurse's concept of patient teaching: Most of the nurses had high levels of concepts and knowledge toward patient teaching. Though nursing service was task-centered at the turn of the century, the emphasis today is put on patient-centered nursing. But we find some of the nurses (39.4%) still are task-centered. After, patient teaching, only a few of the nurses (14.4%) checked this as “normal teaching.”It seems therefore that patient teaching is often done unconsciously. Accordingly it would he desirable to have correct concepts and knowledge of teaching taught in schools of nursing. 2. Contents of patient teaching: Most nurses (97.5%) had good information about content of patient teaching. They teach their patients during admission about their diseases, tests, treatments, and before discharge give nurses instruction about simple nursing care, personal hygiene, special diets, rest and sleep, elimination etc. 3. Time of patient teaching: Teaching can be accomplished even if there is no time set aside specifically for it. -a large part of the nurse's teaching can be done while she is giving nursing care. If she believes she has to wait for time free from other activities, she may miss many teaching opportunities. But generally proper time for patient teaching is in the midmorning or midafternoon since one and a half or two hours required. Nurses meet their patients in all stages of health: often tile patient is in a condition in which learning is impossible-pain, mental confusion, debilitation, loss of sensory perception, fear and anxiety-any of these conditions may preclude the possibility of successful teaching. 4. Prior preparation for patient teaching: The teaching aids, nurses use are charts (53.1%), periodicals (23.8%), and books (7.0%) Some of the respondents (28.1%) reported that they had had good preparation for the teaching which they were doing, others (27.5%) reported adequate preparation, and others (43.8%) reported that their preparation for teaching was inadequate. If nurses have advance preparation for normal teaching and are aware of their objectives in teaching patients, they can do effective teaching. 5. Method of patient teaching: The methods of individual patient teaching, the nurses in this study used, were conversation (55.6%) and individual discussion (19.2%) . And the methods of group patient teaching they used were demonstration (42.3%) and lecture (26.2%) They should also he prepared to use pamphlet and simple audio-visual aids for their teaching. 6. Purposes of patient teaching: The purposes of patient teaching is to help the patient recover completely, but the majority of the respondents (40.6%) don't know this. So it is necessary for them to understand correctly the purpose of patient teaching and nursing care. 7. Condition of patient teaching: The majority of respondents (75.0%) reported there were some troubles in teaching uncooperative patients. It would seem that the nurse's leaching would be improved if, in her preparation, she was given a better understanding of the patient and communication skills. The majority of respondents in the total group, felt teaching is their responsibility and they should teach their patient's family as well as the patient. The place for teaching is most often at the patient's bedside (95.6%) but the conference room (3.1%) is also used. It is important that privacy be provided in learning situations with involve personal matters. 8. Evaluation of patient teaching: The majority of respondents (76.3%,) felt leaching is a highly systematic and organized function requiring special preparation in a college or university, they have the idea that teaching is a continuous and ever-present activity of all people throughout their lives. The suggestion mentioned the most frequently for improving preparation was a course in patient teaching included in the basic nursing program. 9. Recommendations: 1) It is recommended, that in clinical nursing, patient teaching be emphasized. 2) It is recommended, that insertive education the concepts and purposes of patient teaching he renewed for all nurses. In addition to this new knowledge, methods and materials which can be applied to patient teaching should be given also. 3) It is recommended, in group patient teaching, we try to embark on team teaching.
