Background: It is difficult to treat tourniquet-induced hypertension despite adequate anesthesia, and the mechanism of that is not known. And it may be possible that intraoperative continuous infusion of opioid induces preemptive analgesia postoperatively. We investigated the effect of intraoperative continuous i.v. fentanyl on tourniquet induced cardiovascular changes and postoperative preemptive analgesia in total knee replacements. Methods: Sixty patients were randomly assigned to two groups; In study group ($1.5{\mu}g/kg$ loading and $0.5{\mu}g/kg/hr$ continuous infusion of fentanyl before skin incision and tourniquet inflation) and control group (no treatment). Anesthesia was maintained with enflurane (1-2 MAC) and 50% nitrous oxide in oxygen. Arterial pressure and heart rate were compared between two groups. They received postoperative pain treatment with patient-controlled analgesia (PCA) with fentanyl during the postoperative 48 hours after total knee replacement. Visual analog scale (VAS) scores at either rest or movement were used to assess pain. Total fentanyl dose delivered, number of PCA requests, supplemental analgesics, overall satisfaction score and adverse events were evaluated. Results: There were no significant differences between the two groups on cardiovascular changes by tourniquet induced pain effect. VAS, PCA delivered dose and PCA demands at movement in the 24-48 hour decreased in study group compared with control group (P < 0.05). But there were no significant differences between the two groups on the other time periods except 24-48 hour's patient satisfaction and adverse events. Conclusions: We suggest that intraoperative continuous i.v. fentanyl infusion dose not affect cardiovascular change by tourniquet induced pain. But it may induce preemptive analgesia postoperatively.

이제마선생에 의해 제창된 사상체질론은 지난 백년간 후세 사상연구가들에 의하여 발전되어 왔다. 그 중 하나가 바로 권도원 선생에 의해 제창된 체질침(體質針)의 출현이었던 것이다. 체질침범에서는 종래의 방법과는 다른 새로운 맥법(脈法)과 맥도(脈圖) 그리고 체질에 따른 체질침방(體質針方)이 운용되고 있다. 이 체질침방의 경우 실제로는 장부경락(臟腑經絡)의 오행혈을 운용한 사암(舍岩)선생의 오행침을 체질침화(體質針化)한 것이다. 이제마 선생의 체질이론과 사암선생의 오행침이 결합된 것은 실로 역사적인 일이라 하지 않을 수 없다. 권도원 선생은 여덟 개의 맥도와 함께 8체질론을 내세웠으며 스물네개의 사암선생 침방 중 여덟 개를 체질침화하여 이 여덟 체질의 기본 치료처방으로 사용하였다. 본 논문의 저자인 염태환은 지남 1986년 미국 라스베가스에서 열린 동양의학 학술대회에서 이미 24체질론과 24체질 맥도를 제시한 바 있다. 본 논문은 우선 체질의학의 발달에 대한 역사를 간단히 정리하였다. 4체질론에서 시작하여 24체질론까지의 발전되어 온 단계 단계가 여기에 설명되어 있다. 이 설명 속에서 십이경락이 어떻게 사상의학과 이론적으로 결부되는가를 이해하게 되면, 24체질론의 출현이 쉽게 받아들여질 것이다. 본 논문은 이 24체질 중 특히 소음인에 속하는 네 체질에 대하여 초점이 맞추어져 있다. 이 네 개의 체질에 대한 체질맥진법, 맥도, 침법 그리고 한약처방 등이 이 논문에 다루어지고 있는 것이다. 그리고 이 논문의 뒷부분에는 이 네 체질에 대한 저자들의 임상 실례들이 실려 있다. 이 논문의 목적은 새로운 학설을 임상실례와 더불어 소개함으로써, 더욱 많은 한의사들이 관심을 가지고 체질침을 임상에 응용하게 하며 또한 앞으로 치료효과를 객관적으로 밝히기 위한 이중맹검시험(Double blind controlled study) 등이 시행될 수 있는 토대를 마련하고자 하는 것이다.

Maternity nurses' roles are to find out women's various responses related to the health problems during pregnancy, to intervene adequate nursing and supports, and to help them adapt satisfactorily to new situation, such as hospitalization. The purposes of this study are : firstly, to inquire about women's emotional status, feeling of discomfort, and the nursing need during hospitalization because of discomfort, and the nursing needs during hospitalization because of the possibility of abortion by threatened and habitual abortion : secondly, to provide fundamental data for developing adequate nursing intervention and improving hospital management. The subjects of this study were 62 women who were hospitalized, visited out-patient clinic for follow-up, and stayed at home after discharge since August, 1993 from one hospital located in Seoul, from March 23 to April 13, 1994. The questionnaire was consisted of 21 items of emotion(Reliability Cronbach's alpa, .77), 19 items of feeling of discomfort(.79), and 21 items of nursing needs (.89), and nurses' performance according to nursing needs,(.90). These were measured by using Likert Scale and analyzed by using SPSS / $PC^+$ with the descriptive statistics, $X^2$-test, and ANOVA. Research findings are as follows : 1) The subjects' average age, hospitalized days, and gestational age are 32.2, 15.7, 12.9 by respectively. 2) 88.7% of the subjects are getting antepatal care, 66.1% are experiencing 1.75 times of spontaneous abortion, and 82.3% are nuclear family. 3) The Emotions were mainly comprized negative and subjective state of minds such as uneasiness, anxiety, and discomfort. The domains of emotions were related to 'fetus', 'herself', 'hospitalization', and 'husband's 'families', in rank. The highest scored item was "I, above anyone else, am mostly stressed from abortion." 4) The feelings of discomforts were firstly related to 'personal discomfort arising from absolute bed rest', 'meals provided', Usage of hospital, perse', 'health team', in rank. 5) The nursing needs frequently pointed out were 'Nurses kindly explain of me the purpose, method, and results of the lab. test', 'Nurses sincerely pay attention to my word in communication'. The least nursing needs were 'Nurses observe my feces and whether I have constipation or not'. 'When I can't move, nurses help me by holding my arms or pulling my bed'. 6) The highest performed items were 'Nurses observe whether I bleed or not', and 'Nurses give me drug with exact dose in time'. The least performed items was about hospital environment, such as 'Temperature, ventilation & humidity in the room should be controlled'. 7) Besides religion that is related to nursing need with statistically significant difference, none of general characteristics were related to emotion, feeling of discomfort, and nursing needs.

Objectives : The purpose uf this study was to evaluate the effect of Choksmni$(ST_{36})$ moxibustion in hypertensive patients who showed sudden elevation of blood pressure. Methods : Among patients admitted to Woosuk University Hospital from June to September 2004, sixty-one patients who had shown sudden elevation in systolic blood pressure over 100mmHg were chosen by random sampling and divided into a treatment group (Choksamni moxibustion group) and a control group. In the Choksamni $(ST_{36})$ moxibustion group, moxibustion was done at the point between tibial tuberosity and head of fibula where the $ST_{36}$ is known to be located. Direct moxibustion was practiced on the patients 5 times with an increase of size from a grain of rice to a bigger cluster. Male patients were chosen to practice on the left meridian and female patients were chosen to practice on the right meridian point. Changes in blood pressure after He moxibustion were checked 4 times at tine intervals of 30 minutes. In the control group, the patients took bed rest without my medical treatment. The two groups were compared in order to demonstrate whether then were any remarkable changes in depression of blood pressure. Results : There were significant decreases in the systolic and diastolic blood pressure before and after moxibustion. We found significant decreases in systolic blood pressure at 60 minutes, 90 minutes, and 120 minutes ana diastolic blood pressure at 120 minutes in the patient group compared with the control group. Conclusions : There was a statistically significant depressing effect on blood pressure elevation observed in the group with moxibustion at $ST_{36}$ versus the control group without any medical treatment.

The purpose of this study was to investigate the correlation between the knowledge and educational needs related to recurrent in coronary artery bypass graft patients as a basis to provide an individual nursing education for the population. The subjects consisted of 110 patients who had coronary artery bypass graft(CABG) at Asan Medical Center in Seoul and Sechong hospital in Buchon. Data was obtained from a knowledge questionnaire and a learning needs questionnaire between November 1998 and February 1999. Data were analyzed using SAS program for Wilcoxon rank sum test and Spearman correlation coefficient. The results were as follows : 1. With regard to the 18 items to measure knowledge, the mean (median) of items 'don't know' was 4.9(4) items. The mean (median) of items answered wrong was 3.2(3) items. The number of items answered 'don't know' tend to show higher in those who had less education, blue color jobs and myocardiac infarction history than in their counter parts. There were higher frequency of items answered 'don't know' in those who had no hypertension 2. With regard to the level of knowledge by questionnaire about CABG, The most "I dont know" (59.1%) highly response was 'He has to be treated with anticoagulant drug to prevent revasculized vessel from obstructing.' The seond highest response (56.4%) was 'If you were hypotensive, the coronary attack would collapse. 'During the hospitalized day, the patient has complete bedrest.' The highest error probability was cholesterol has not to intake.', 'After surgery, the sexual life is need controlled for 1 year. 3. The mean of educational needs was 3.38. With regard to the level of learning needs by sentence about CABG, 'Food that benefit heart disease', 'Recurrence possibility of heart disease', 'Management method of operation site', 'Risk symptom that visit hospital or report immediately' were higher than other sentenses. With regard to the level of learning needs by factor 'food(5 items)', 'disease(9 items)' and 'exercise(3 items)' showed the highest than other factors. The educational needs by patients characteristics tend to show higher in males, under the age of 49, middle or high school degree, previous experience of admission with coronary artery disease, history of myocardial infarction, expierience of PTCA, history of cerebro-vascular accident, previous expierience of smoking than in their counter parts. 4. The number of items answered 'don't know', wrong and correct weren't correlated with the level educational needs. As the results, the number of items answered 'don't know' tend to show higher in those who had less educated, blue color jobs and myocardiac infarction history than in their counter parts. There were higher frequency of items answered 'don't know' in those who had no hypertension .There were higher frequency of items answered 'don't know' on anti-thrombolitic theraphy, hypotension and pain relief. Also there were higher frequency of items answered wrong on bed rest period, cholesterol intake, and sexual life. Educational needs were higher in young age group, had previous experience of procesure and history of other disease. And when we educate CABG patients, education for diet, recurrence possibility of disease, management methods of operation site and risk symptom should be emphasized.

Objectives : Moxibustion has been become very useful tool to prevent and treat various diseases with acupuncture in oriental medicine. Expecially, moxibustion combining the heat stimulation and chemical stimulation of Artemisiae Argyi has a non-invasive characteristics comparing to the other therapeutic tools. However, because the moxibustion makes the patient's skin be burn by the combustible feature of moxibustion, most of people have been scared of being scald. Methods : In this study, we have developed new non-combustible moxibustion tools in collaboration with company (Hana Medical, co. and ICURE, co.) and tested the efficacy through effects of moxibustion of Cheon-chu $(ST_{25})$ on the abdominal thermography of health subject. The non-combustible moxibustion has main characteristics of controlled heating to inhibit being scald and heat stimulation lasting over 1 hrs. Also, to induce the chemical stimulation, the bottom contacting with skin was coated by the extract of artemisiae argyi. The volunteers who participating in this study had taken rest for 20 - 30 mins in room temperature $(23-25^{\circ}C)$ before the examination and informed them what to prohibit smoking, drinking and administration of drug for the previous day The thermography of abdomen including a below part of the chest was taken using Infra-Red Imaging System (IR 2000, MEDI-CORE Co., Korea) by time interval of 15 minutes. Results : The results showed that moxibustion of Cheon-chu $(ST_{25})$ had more potencies of changes on all the ROIs of abdominal thermography than those of control group. Also, it was observed that the quantities of thermal changes following moxibustion of Cheon-chu $(ST_{25})$ been increased significantly comparing that of control group at all the ROIs (region of interest). Observed the thermography classified by ROI, however, moxibustion of Cheon-chu $(ST_{25})$ could modulate ipsilateral specific areas concerning to the abdominal pathway of Stomach Meridian. Conclusion : These results suggest that new non-combustible moxibusion has some similarity as like as the conventional moxibustion and moxibustion of Cheon-chu $(ST_{25})$ may modulate thermal changes of abdominal areas.

The study was conducted to test the effectiveness of thermotherapy for high school girls who suffered from disruption in school activities through dysmenorrhea, and to study the extent of its availability in school infirmaries as one of the nursing methods. The test for the study was designed to make a contrast between half of the subjects (20) who did not receive the thermotherapy, and the rest (20) who did during the period from February 15th to April 14th, 2001. Measurements were taken of the subjects who complained of painful menstruation by a set of variables. The variables that were established and complemented by Hur, Mung-heang (1985) consist of 29 items that assess the dysmenorrhea and vitality through the symptoms of primary menstruation visually. Spsswin was used to analyze the data. The Cronbach-${\alpha}$ method was used for statistic confidence, and the test effect of both the subjects and the contrary ones was analyzed by way of T-test. The conclusions are as follow. (1) The hypothesis 1 states that the subjects with themotherapy have a lower degree of dysmenorrhea rather than the contrary ones without it. By the above assessment, there was a quantitative difference between the subjects at 39.40, and the contrary ones at 22.0. After the themotherapy, the degree of dysmenorrhea in the subjects was low indicating that there is a still 5% chance of statistic meaningful difference (t= 2.651. P= .012). As a result, the first hypothesis was accepted. (2) The hypothesis 2 states that the subjects with themotherapy have a different primary menstruation than those without. Data indicate that there was a difference of -5.95 and -4.80. The subjects showed low degrees. Since it was statistically insignificant (t=-1.398, P=.170), the second hypothesis was rejected. (3) The hypothesis 3 states that the subjects with themotherapy have a different vitality. The vitality was measured in three aspects. (1) pulse rate (/min) The hypothesis 3' states that the subjects with themotherapy have the different pulse rate from those without. Data indicate that there was no statistically meaningful difference between the two groups (t=.237, P=. 814). Therefore, the third 1st hypothesis was rejected. (2) Respiration rate The hypothesis 3' states that the subjects with themotherapy have a different respiration rate between pre-thermotherapy and post-thermotherapy. in contrast with the ones without it. The data show that there was no statistically meaningful difference (t=.133. P=.895). A little respiration rate difference was shown between pre-and post-. Likewise. the third 2nd hypothesis was rejected. (3) Blood pressure In the 3rd sub-hypothesis that there would be a difference between experimental and controlled groups was also rejected. because there was no statistically significant difference between the contracting blood pressure and the relaxing blood pressure. In terms of vitality. the pulse rate, respiration rate and blood pressure have no statistical meaning but the first two ones show the decreasing in the rate. In short, though exclusive studies focused on thermo therapy have not been conducted and the comparison can not be made, this study shows not only that the thermotherapy is very effective to dysmenorrhea, but also that it can be available in school infirmaries as one of the nursing methods.
