Our health is intimately connected to the health of our environment. The contemporary world view which sees a radical distinction between humans as subjects and world as object can obscure our recognition of how much we rely on nature for health and survival. Indigenous traditions and contemporary scholars remind us that we live in a universe in which all things are connected, and in which nature continues to offer its gifts in co-creative partnership for the health and wellbeing of all. Living in awareness of our relationship with nature enables us to open more to the experience of nature's nurturing. Many complementary therapies derive from ancient practices that involve nature in healing partnership. Essential oils have been used for thousands of years. Hippocrates claimed that the way to health was through aromatic baths and massages. Much anecdotal evidence exists regarding aromatherapeutic positive effects on recipients. Aromatherapy is a branch of complementary or alternative therapy which is increasing in popularity, yet has scant scientific credibility. Aromatherapy should be defined as treatment using odors and practised as such. However, essential oils are usually used in conjunction with therapeutic massage and often combined with counselling of some kind. Aromatherapy complements and enhances the therapeutic powers of massage. Massage is one of the most wonderful ways to relax and is throughly beneficial to health. Massage can help unknot tense and aching muscles and other minor symptoms of stress, leaving patients fresh and energized. As the use of aromatherapy within a health care setting has grown so rapidly in recent years, and will continue to do so, the need for suitable training has become apparent. No health service can afford the risk of having staff who are inadequately trained in the practice of aromatherapy using essential oils incorrectly on those in a state of ill-health, especially if the essential oils used are not to a standard suitable for therapeutic use. Training to an acceptable level in aromatic therapy is essential for safety and effectiveness. Knowledge of the nature and make-up of essential oils, their effect on the body and the emotions, and how, when, and where to apply them is imperative in order for them to be beneficial to a patient's health. In order to achieve best practice, further research is necessary to explore the use of aromatherapy in the management of multiple disorder.

Ninety patients underwent mitral valvular heart surgery associated with or without aortic valve surgery and subjected to a clinical study in relation to their control of postoperative atrial fibrillation. There were 26 males and 64 females ranged in age from 16 to 56 years with a mean of 35.2 years. Systemic arterial embolizations were observed in 11 patients [12.2%]. Four patients of them were in normal sinus rhythm and 7 in atrial fibrillation. Out of these, left atrial thrombi were found only in 2 at the operation. Intraoperatively confirmed left atrial thrombi were in 16 patients [17.7%] of all 90 patients: Eleven patients occurred at the age of more than 40 years, 14 were in atrial fibrillation and 2 only had previous episodes of systemic arterial embolization. Sixty three patients underwent isolated mitral valve surgery [OMC 28, MVR 35] and 27 patients associated with aortic valve surgery along with mitral valve [OMC+AVR 13, MVR+AVR 14]. Preoperatively, 44 patients [48.9%] were in normal sinus rhythm. Of them, 35 patients [79.5%] revealed normal sinus rhythm thoroughly after operation without any aid of digitalis or quinidine and 5 patients [11.4%] restored normal sinus rhythm with digitalization alone. Other 3 patients converted to normal sinus rhythm with the addition of quinidine, however, in 1 patient who was resistant to quinidine therapy, electrocardioversion was carried out on the postoperative third week showing normal sinus rhythm. Thus, the most atrial fibrillations that occurred for the first time in the postoperative period, were able to reverted to normal sinus rhythm responding well to antiarrhythmic therapy. Preoperatively, 46 patients [51.1%] were in atrial fibrillation. Of them, only 5 patients returned to sinus rhythm after operation without any aid of digitalis or quinidine and other 5 restored normal sinus rhythm with digitalization: namely 2 restored within early postoperative period and 3 after more than 3 months. Eight patients well responded to quinidine therapy showing normal Sinus rhythm. So far, 25 patients have remained in persistent atrial fibrillation on 6 to 36 months follow-up. In view of these, 17 patients [68%] were over 40 years of age, 22[80%] had long duration of symptom over 5 years and 10[40%] have had atrial thrombi before operation. Left atrial dimension were still more than 40mm in 21 patients on follow up M-mode echocardiogram. One month after operation, 87 hospital survivors were improved by at least one functional NYHA class. There were 3 operative deaths [3.3%, bleeding 1, LCOS 2] and 4 late deaths [LCOS 1, valve thrombosis 1, late bleeding 1, fulminant hepatitis 1] during follow-up period. According to our limited experience, we may conclude that better results will be expected with the addition of quinidine therapy judiciously in the cases of postoperative persistent atrial fibrillation who were aged or had longer history of symptom and left atrial thrombi.

Background: Descending necrotizing mediastinitis(DNM) is a serious complication originating in odontogenic or oropharyngeal infection with previously reported mortality rates of 25% to 40%. We retrospectively reviewed the 4 years of our surgical drainage and debridement in DNM. Material and Method: We studied 7 cases diagnosed as DNM from 1997 through 2000. Primary oropharyngeal infection lead to DNM in four cases(57%) and odontogenic abscess in three cases(43%). All patients were received emergent cervicotomy and thoracotomy or sternotomy for debridement of necrotic tissue and mediastinal or pleural drainage. Result: Five cases were evolved well and were discharged after a mean of 42 days. Two patients(28.6%) died. Three patients required reoperation due to local surgical complication; empyema(two) and impending cardiac tamponade. One of these patients died on 12 post-reoperative day due to great vessel erosion, renal and respiratory insufficiency. The other patient died of broncho- esophageal fistula and asphyxia on 10 postoperative day without reoperation. Conclusion: On the basis of experience accrued in treating these patients, early diagnosis by cervicothoracic computed tomographic scan of neck and thorax aids in rapid indication of a surgical approach of DNM. We emphasize that performing early surgical drainage and debridement of necrotic tissues with intensive postoperative care can significantly reduce the mortality rate.

A right thoracotomy was used for the reoperation or mitral valve of 15 patients who had previously undergone a cardiac operation through a median sternotomy. In our experience. this approach provided dn excellent exposure of the nlitral valve and easy cannulations of both cavie with minimal dissection, ilvoiding any damage of cardiac and major vessels during re-sternotomy Arterial cannulation was performed in the ascending aorta in 13 patients And in the femoral artery in 2 patients. In earlier cases, venous cannulation was done in the SVC And IVC through the right atrium and snared. In later cases, this could be done without snaginly of both cavae or by placing a silgle light-angled catheter into the right atrium. Crystalloid cardioplegic solution was infused for myocardial protection. Hypothermia was controlled at 20\ulcorner$25^{\circ}C$. For defibrillation, internal paddles were used In one patient while sterilized external paddles were used in 10 patients. In the remaining four patients. however. the heart beat spontaneously The respirator could be weaned within 48 hours alter the operation and no pulmonary complication was observed. One out of the 15 patients expired due to sudden attack of ventricular tarchycardid developed ten days after the operation, but the rest of the patients were discharged with good condition.

Background: Medical treatment of multiple drug resistant(MDR) pulmonary tuberculosis has been quite unsuccessful. We analyzed our experience to identify the benefits and complications of the pulmonary resection in MDR pulmonary tuberculosis. Material and Method: A retrospective review was performed in 27 patients who unerwent pulmonary resection for MDR pulmonary tuberculosis between January 1994 and March 1998. Mean age was 40 years and the average history of diagnosis prior to surgery was 3.1 years. All had resistance to an average of 4.4 drugs, and received second line drugs selected according to the drug sensitivity test. Most patients (93%) had cavitary lesions as the main focus. Bilateral lesions were identified in 19 patients (70%), however, the main focus was recognized in one side of the lung. Eleven patients (41%) were converted to negative sputum smear and/or culture before surgery. Result: Pneumonectomy was performed in 9 patients, lobectomy in 16 and segmentectomy in 2. There was no operative mortality. Morbidity had occurred in 7 patients (26%), prolonged air leak in 3 patients, reoperation due to bleeding in 2, bronchopleural fistula in 1, and reversible neurologic defect in 1. Median follow up period was 15 months (3-45 months). Sputum negative conversion was initially achieved in 22 patients (82%), and with continuous postopertive chemotherapy negative conversion was achieved in other 4 patients (14%). Only one pneumonectized patient (4%) failed due to considerable contralateral cavity. Conclusion: For patients with localized MDR pulmonary tuberculosis and with adequate pulmonary reserve function, surgical pulmonary resection combined with appropriate pre and postoperative anti-tuberculosis chemotherapy can achieve high success rate with acceptable morbidity.

Colorectal cancer is the second most frequent malignant tumor in the United States and fourth most frequent tumor in Korea. Surgery has been used as a primary treatment modality but reported overall survivals after curative resection were from $20\%\;to\;50\%$. Local recurrence is the most common failure in the treatment of locally advanced colorectal cancer. Once recurrence has developed, surgery has rarely the role and the five year survival of locally advanced rectal cancer is less than $5\%$, in spite of massive combination therapy. Intraoperative radiotherapy (IORT) with or without external beam irradiation has been advocated for reducing local recurrence and improving survival. The recent report of local failure by this modality was only $5\%$, this indicated that significant improvement of local control could be achieved. We performed 6 cases of IORT for locally advanced colorectal cancer which is the first experience in Korea. Patient's eligibility, treatment applicator, electron energy, dose distribution on the surface and depth within the treatment field and detailed skills are discussed. We hope that our IORT protocol can reduce local failure and increase the long term survival significantly.

Purpose: This study was performed to evaluate of practicum by using standardized patient(SP) for nursing assessment. Method: This study had 2 steps. The 1st-step was pre-intervention stage including selection of a learning title, formation of case scenario, training of SP and developing the evaluation tools for students' clinical competence to assessment, 6 categories 29 items. The 2nd-step consisted of intervention and evaluation stages. 34 nursing students divided 2 groups participated in assessing the SP. Evaluation of each group was performed by 2 nursing professors. All students recorded their feelings after assessing the SP. The SP also evaluated about nursing students' attitude toward the SP. Results: ICC(Interclass correlation coefficient) between 2 groups was over 0.7 all categories. Students' assessing score(range 0-1) was muscular-joint function status(0.41), nutritional status(0.39), history taking(0.38), IADL(0.18), ADL(0.15), and emotional status (0.07). The mean scores of the nursing students' attitude by SP was 4.03(range 1-6). Also most students showed positive reactions to the education using SP because they had the chance to experience what they could not practice in clinical setting. Conclusion: The evaluation tool revealed high reliability. Nursing students' clinical competence was below average. But they took a good attitude to SP. We recommended further research using SP with various disease.

Purpose: To introduce our early experience with intensity-modulated radiotherapy (IMRT) in the treatment of nasopharyngeal carcinoma. Methods and Materials: Eight patients who underwent IMRT for no disseminated nasopharyngeal carcinoma at the Asan Medical Center between September 2001 and November 2002 were evaluate by prospective analysis. According to the 1997 American Joint Committee on Cancer staging classification, 5 had Stage III, and 3 had Stage IVB disease. The IMRT plans were designed to be delivered as a 'Simultaneous Modulated Accelerated Radiation Therapy' (SMART) using the 'step and shoot' technique with a MLC (multileaf collimator). Daily fractions of 2.2-2.5Gy and 1.9-2Gy were prescribed and delivered to the GTV and CTV and clinically negative neck node, respectively. The prescribed dose was 70A-79.0Gy to the gross tumor volume (GTV), 60Gy to the clinical target volume (CTV) and metastatic nodal station, and 46Gy to the clinically negative neck. All patients also received weekly cisplatin during radiotherapy. Acute and late normal tissue effects were graded according to the Radiation Therapy Oncology Group (RTOG) radiation morbidity scoring criteria. Results: Follow-up period was ranging from 5 to 18 months. All patients showed complete response and loco-regional control rate was 100% but one patient died of malnutrition due to treatment related toxicity. There were no Grade 3 or 4 xerostomia and all patients had experienced improvement of salivary gland function. Conclusion: 'Simultaneous Modulated Accelerated Radiation Therapy' (SMART) boost intensity-modulated radiotherapy technique allows parotid sparing as evidenced both clinically and by dosimetry. Initial tumor response and loco-regional control was promising. It is clinically feasible. A larger population of patients and a long-term follow-up are needed to evaluate ultimate tumor control and late toxicity.

Objectives : Anterior cervical discectomy and interbody fusion has become a well-accepted surgical treatment of degenerative cervical diseases. Implatable cages have a stabilizing effect without plates and no need for autogenous bone graft. The authors evaluates the effect of implatable titanium cage(RABEA) on the clinical and radiological outcomes. Methods : 34 patients with symptomatic cervical degenerative diseases due to one level disc pathology were underwent anterior cervical discectomy and interbody fusion with titanium cages(RABEA) which were not filled with cancallous bone grafts from January 1999 to May 2001. Patients with osteoporosis and older than 65 years were not included. Among them, 15 patients could be followed-up for at least 1 year. The authors retrospectively reviewed the charts and radiographic data. Mean follow-up period was $1.3{\pm}0.2years$. Results : Clinical results according to the Odom's criteria was exellent and good in 14(93%) patients. One patient with fair result showed complete loss of the disc space height due to settlement of the cage. Preoperatively, the mean height of the disc space(${\pm}$standard deviation) was $3.42{\pm}1.10mm$(range 2.0-5.5mm), and at 1 day postoperatively it was $7.88{\pm}0.90mm$(range 6.50-9.0). The mean height of the disc space after 1 year was $6.50{\pm}1.38mm$(range 3.0-8.0). The restoration of the height was statistically significant(p<0.05). The mean height after 1 year was $82.7{\pm}15.9%$ of the height at 1 day postoperatively. Preoperatively the mean value of the cervical lodortic angle was $21.8{\pm}11.8^{\circ}$ and 1 year postopertively, it was $24.5{\pm}8.3^{\circ}$, which was statistically not significant. All patients showed no abnormal movements on flexion and extension lateral film after 6 months. Conclusion : Implantable titanium cages appear safe and effective in selected patients, and their use helps to avoid complications associated with bone graft harvest. Subsidence of the cage seems to be a potential risk factor for recurrence of the symptoms. For long-term results, a longer follow-up is required.

The purpose of this study is to investigate work environment and job satisfaction of dental hygienists. The survey had collected 373 dental hygienists in Daegu and Gyeongsangbuk-do areas. The results were as follow; 1. The overall average of job satisfaction was 3.30. 2. Differences in the general characteristics and job satisfaction were significantly high with high age, high educational level and high work experience for married people. It was also significantly high when people worked in Gyeongsangbuk-do rather than in Daegu. 3. Differences in work environment and job satisfaction were significantly high in large size of the hospital, patient management and consultation services rather than assistance, monthly salary rather than annular salary, the presence of training opportunity and benefit for long-term worker, and more other vacations and annual vacations. 4. The influence factors of general characteristics on job satisfaction were education, work area and marriage in order ($R^2$=0.092). 5. The influence factors of work environment on job satisfaction were training opportunities, benefit for long-term worker, size of hospital, area of work and incentives in order($R^2$=0.092). From the above results, in order to improve job satisfaction of dental hygienists require a reasonable working environment considering the realistic situation improved.
