This study was performed to investigate the stress level and health-related behaviors of nurses and to provide basic information for developing educational programs in the health care field. The subjects of this study were 197 nurses and 94 nursing assistants working at hospitals in the Kyung-nam area. A survey was conducted using a self-administered questionnaire in November, 2002. The results were as follows : The average age and work experience of the subjects were 26.9 and 5.6 years, respectively. The number of respondents in the shift and non-shift operations was equally distributed. The mean height and weight were 161.2 cm and 52.7 kg, respectively. Even though the average body mass index (BMI) and obesity index were normal in the subjects, 9.2% of the subjects were overweight/obese, while 28.9% of the subjects were under weight, according to the obesity index. The mean score of stress was 27.5 \pm$\pm$ 4.6 out of 50 points. Most of the subjects were highly stressed about the amount of their work, problems regarding their future, and relationships with their superiors. With regard to changes in food intake due to stress, 44.1% showed an increased intake, while 32.3% showed a reduced intake. The degree of health consciousness of the married nurses, those over 36 years of age, and those with over 10 years of nursing experience was significantly higher than that of the unmarried nurses, those under 35 years of age, and those with under 10 years of nursing experience (p<0.01). Fifty-one point three percent of the subjects thought their health status was unhealthy. Fifty-seven percent of the subjects had tried weight control. Their main reason for trying weight control was to have a slender figure (62.3%), and their methods of weight control were moderation in intake(45.6%), exercise and dieting (36.9%). TV/radio (49.5%) and newspaper/magazines (47.1%) were the primary sources of nutritional and health information for the subjects, and professional (25.1%) and the internet (13.4%) were ranked relatively highly. The food components of most concern to the subjects during meal time were (in order of importance) fats (51.9%), calories (40.2%) and salt (35.1%). The subjects considered 'taking a rest' (73.5%) as the most important factor in maintaining an optimal health status, followed by self-relaxation (56.4%), moderation in diet (39.5), bathing or using a sauna (25.7%) and exercising (22.7%).

Background: This study investigated whether current smoking and a higher nicotine dependency were associated with chronic low back pain (LBP), lumbar related leg pain (sciatica) and/or radicular neuropathic pain. Methods: A cross-sectional study was conducted on 150 patients (mean age, 60.1 ± 13.1 yr). Demographic data, the International Association for the Study of Pain (IASP) neuropathic pain grade, STarT Back tool, and the Fagerström test were completed. A control group (n = 50) was recruited. Results: There was a significant difference between current smokers and nonsmokers in the chronic LBP group in the mean pain score (P = 0.025), total STarT Back score (P = 0.015), worst pain location (P = 0.020), most distal pain radiation (P = 0.042), and in the IASP neuropathic pain grade (P = 0.026). There was a significant difference in the mean Fagerström score between the four IASP neuropathic pain grades (P = 0.005). Current smoking yielded an odds ratio (OR) of 3.071 (P = 0.011) for developing chronic LBP and sciatica, and an OR of 4.028 (P = 0.002) for obtaining an IASP "definite/probable" neuropathic pain grade, for both cohorts. The likelihood for chronic LBP and sciatica increased by 40.9% (P = 0.007), while the likelihood for an IASP neuropathic grade of "definite/probable" increased by 50.8% (P = 0.002), for both cohorts, for every one unit increase in the Fagerström score. Conclusions: A current smoking status and higher nicotine dependence increase the odds for chronic LBP, sciatica and radicular neuropathic pain.

The purposes of this study were to find factor which influence on the selection criteria of food supplier. Questionnaire were distributed to 52 general hospitals with more than 400 beds located in Seoul and Kyongin province, and responded questionnaires were collected from 44 dietetic departments (84.6%) and 18 purchasing departments (34.6%). The main results of this study can be summarized as follows: (1) supplier selection criteria include quality, service, cost and supplier competency. (2) With having been met with tight competition and market opening, hospitals plan a strategy to improve quality, service and they tend to have more interest in various supplier selection criteria. (3) Purchasing departments estimate more highly the rate of reflection in considering supplier selection criteria than the rate of importance about cost criteria, which reveals that purchasing departments sensitively respond to cost cutdown. (4) When selecting suppliers, a significant(p<.01) influence of stability of supplier industry environment on the selecting criteria such as the importances of quality, service, and supplier quality are recognized only after recognizing the stability of food delivery industry. Food supplier industry secures stability more quickly through major companies' participation in food distribution industry and this will reveal the importance of supplier selection criteria. (5) Suppliers which are selected by the quality criteria, service criteria, supplier quality criteria make efforts to communicate with foodservice departments, to give more proper information about substitute food, new product, and to make commitments, while suppliers which are decided by cost criteria do not establish supportive relationships with foodservice departments.

Chronic postsurgical pain (CPSP) is an unwanted adverse event in any operation. It leads to functional limitations and psychological trauma for patients, and leaves the operative team with feelings of failure and humiliation. Therefore, it is crucial that preventive strategies for CPSP are considered in high-risk operations. Various techniques have been implemented to reduce the risk with variable success. Identifying the risk factors for each patient and applying a timely preventive strategy may help patients avoid the distress of chronic pain. The preventive strategies include modification of the surgical technique, good pain control throughout the perioperative period, and preoperative psychological intervention focusing on the psychosocial and cognitive risk factors. Appropriate management of CPSP patients is also necessary to reduce their suffering. CPSP usually has a neuropathic pain component; therefore, the current recommendations are based on data on chronic neuropathic pain. Hence, voltage-dependent calcium channel antagonists, antidepressants, topical lidocaine and topical capsaicin are the main pharmacological treatments. Paracetamol, NSAIDs and weak opioids can be used according to symptom severity, but strong opioids should be used with great caution and are not recommended. Other drugs that may be helpful are ketamine, clonidine, and intravenous lidocaine infusion. For patients with failed pharmacological treatment, consideration should be given to pain interventions; examples include transcutaneous electrical nerve stimulation, botulinum toxin injections, pulsed radiofrequency, nerve blocks, nerve ablation, neuromodulation and surgical management. Physical therapy, cognitive behavioral therapy and lifestyle modifications are also useful for relieving the pain and distress experienced by CPSP patients.

This study was done to determine the situations of stress incontinence(SI) and the differences in general characteristics, obstetrical history and SI related variables between women with stress incontinence and normal women. The design for study was a descriptive study. The number of subjects consisted of 156 women who were selected by systematic random sampling in Kwangju city. Data collection was done with the modified Hendrickson's Stress Incontinence Scale(1981) which was analyzed using frequency and percentiles. The results were as follows : 1. The stress incontinence (SI) rate of the sample was 64.1% and the majority of the women(40.9%) had experienced SI for a period of five years(the mean period was 2.7 years) without any treatment or care(83.0%). The amount of SI was from one drop(40.0%) to one teaspoon(16.7%) daily. 2. Items on the SI scale had the scores ranging from 4 to 44 with a mean score of 13.7 which showed mild SI. 3. The priority of provocative factors for SI were abdominal tightening(83%), coughing(58%), laughing(52%), sneezing(40%), steeping(18%), sudden standing(17%), nose blowing(13%), heavy exercise(11%), rapid walking up-stairs(10%) and excitment (9%) in that order. 4. There were no significant differences in age, education, spouse, job and income between the women with SI and the normal women. 5. There were no significant differences in the age at the last delivery, age of last baby. number of vaginal, or cesarean deliveries, or abdominal operations between the women with SI and the normal women. It can be concluded that SI in women has a high incidence nth various provocative factors but it is relatively mild SI on a daily basis and generally there has been no treatment. It is suggested that a descriptive study of emotional problems and precipitating variables in SI women will increase the knowledge of SI.

A physician assumes toward his patient the obligation to use such reasonable care and skill as is commonly possessed and exercised by physicians in the same general line of practice in the same or similar localities and to use his best judgment at the times. Medical disputes between physicians and patients are, ever more increased in these days as human body, happens to cause a variety of changes in body unlike the function of machine. Such increased trends of medical disputes became a problem in common across the word under the influence of affluent living standard, high consciousness of life value and right by today's people. The aim of this dissertation is oriented to forming a physician's responsibilities in medicalcare accidents arising between physicians and patients. A general physician, for example, has not been negligent merely because, a specialist might have treated the patient with greater skill and knowledge. However, the fact that a physician may have acted to the best of his ability will not avoid legal problems for damages resulting from substandard treatment, that is the degree of care and skill which is to be expected of the ordinary practitioner in his field of practice. The duty of a physician who is, or holds himself out to be, a specialist is greater in the field of his specialty than one who is a general physician. A patient's consent to routine medical procedures is implied from the fact that patient comes to the physician with a medical problem and voluntarily submits to the procedures. For the more serious medical procedures and for major operations, however, it is preferable for the physician to have the patient's consent in writing, to facilitate proof of the consent in the event of a dispute or litigation. Suppose that mistakes on the part of physicians are likely to be blamed in all cases of malpractice. Then it will create a sort of shrinkage in activities of medical treatment. There should be some limitation on excessive application of 'The thing speaks for itself' on mistakes by physicians and availablity of cause and effect. It is a matter of complicity as well as a matter of importance to draw a definite boundary on responsibilities of physician. A series of further research on this particular aspect is strongly urged.
