The purpose of this study was to get some basic data for health care for working women, especially or hospital nurses. The number of subjects was 796 nurses from one general hospital and four private educational hospitals. The data were collected from February to April, 1988 using the questionnaire "Symptom Table on Fatigue Perception" designed by the Research Committee of Industrial Fatigue in Hygienic Association of Japan Industry. The collected data were analyzed using means and standard deviations for the subjective symptoms of fatigue and each item as an independent variable was analyzed by T-test and ANOVA test. The results are as follows 1) The mean score for degree of fatigue was 1.89 and the degree of fatigue for physical symptoms had highest score of 2.04, the next was psychological symptoms at 1.89, and neuro -sensory symptoms were the lowest at 1.74. Among the fatigue symptoms, the item scored most frequently was "Legs feel heavy" with a mean score of 2.40 and the least frequent item was "My hand and foot trembled" with a mean score of 1.40. 2) With the respect to the general characteristics of subjects, there were statistically significant difference according to age (F=17.039, p=.000), state of marriage(t=5.381, p=.000) presence of children(t=5.134, p=.000), clinical experience (F=16.663, p= .000), present position(F=18.204, p=.000), working place(F=12.598, p=.000), duty time(F=9.068, p=.000), monthly wages(F=7.361, p=.000). satisfaction about the pay and treatment at work(t=-5.511, p=.000), relation the doctors(t=-4.593, p=.000) the doctors(t=-4.593, p=.000)

Cancer has been considered a life-threatening disease and coping patterns could have a strong impact the physical and psychological health of patients and their family. The purpose of this study was to identify the change of coping patterns according to the phases of illness in the patients with cancer and their family caregivers and to compare the coping patterns of patients with those of their caregivers. The phases of illness consisted of 1st(initial) stage, 2nd(metastatic or recurred) stage and 3rd (terminal) stage based on literature. The coping methods were measured using the modified Ways of Coping Questionnaire by Lazarus & Folkman(1984). Seventy-nine patients(35 in stage 1, 31 in stage 2, and 13 in stage 3) and ninety-two caregivers (38 in stage 1, 30 in stage 2 and 24) agreed to participate from two general hospitals in Seoul and Choongnam. No significant changes were found in the coping patterns according to the phases of illness in both groups. Patients in stage 2 and caregivers in stages 2 and 3 problem-focused coping methods were significantly used more than emotion-focused coping methods. Patients in stage 1 significantly used two coping strategies that were cognitive reconstruction and emotion expression more than caregivers. Patients in stage 2 significantly used emotion-focused coping methods including minimizing threat, blame, and emotion expression excepting wishful thinking more than caregivers. We need more research to identify the relationship between the coping methods and their efficiencies through longterm observation and attempt to develope the nursing interventions that could have an improvement on positive coping methods and provide guidance on the problems the patients experience.

Issues related to the elderly have been recognized in Korea and nursing schalors have tried to study these issues. It is hard to say which the direction we, are going or have to go, since there has been little systemic effort to establish gerontological nursing field yet. Therefore, it is necessary to find out the trend and the guidelines of gerontolotical nursing studies for the future. Dissertation and published articles related to the elderly in the nursing field from 1991 to the Feburary of 1997 were are reviewed. Total 127 studies were analysed in terms of concept, design/methodology, and results, and the nature and issues of the gerontologic nursing studies in Korea were explored. The results are as follows : 1. There was no clear chronological definition of the elderly. 2. The most popular research design was an exploratory/descriptive study. 3. The major concepts studied were physical and mental health. 4. Among those studies using instruments which were developed and modified and/or translated by researchers, the reliability and validity were rarely reported. 5. Theory based studies were rare. We suggest the following issues for future studies : 1. The chronological and other criteria related to the defition of elderly is needed. 2. Physiopsychosocial characteristics of Korean elderly and their mangements in terms of intervention studies need to be conducted more systemically. 3. Social issues from the change of types and functions of family such as single elderly family need to be studied. 4. Participation in and collaborate with other disciplins are needed. 5. Development and test of instruments to measure phenomena or concepts is needed. 6. Macroscopic approach such as policy also needed. 7. Theory based studies are needed.

Purpose: The aim of this study was to develop a substantive theory on self-management conducted by the adolescents with chronic kidney disease from their lived experience. Methods: Data was collected through in-depth interviews from May to December in 2015 with thirteen adolescents with chronic kidney disease. The data collected were analyzed on the basis of Strauss and Corbin's grounded theory. Results: The core of the category found in this study was "overcoming the unstable sense of self- control and integrating disease experience into their life". The causal conditions triggering the central phenomenon were "restriction in daily life" and "manifestation and aggravation of symptom". The central phenomenon in the experience of self-management within the adolescents with chronic kidney disease was "unstable sense of self control". The intervening condition for unstable self control were "micro system support" and "motivational resources". This study found that the adolescents with chronic kidney disease followed a series of strategies when they faced the central phenomenon, including; passive coping, reappraisal of illness, active coping, compliance with treatment, controlling physical activity, and adjusting school life. With these strategic approaches, the adolescents with chronic kidney disease could maintain their active lifestyles and achieve their health behaviors. The process of self-management by these adolescents passed through four phases; limited experience caused by diseases, effort for normalization, reorganizing their daily lives, and integration with daily lives and self-management. Conclusion: This Study explored the process and experience of self-management of adolescents with chronic kidney disease. These findings can be used for basis for developing substantive theory and nursing intervention strategy for adolescents with chronic kidney diseases.

We have previously shown that the specific phosphatidylinositol 3-kinase inhibitor LY294002 (LY29), and its inactive analog LY303511 (LY30), inhibit a monocyte chemoattractant protein-1 (MCP-1) expression in human umbilical vein endothelial cells; these results suggest the potential of LY30 as an anti-inflammatory drug. In this study, we determined the effects of LY30 on the production of various inflammatory cytokines in human macrophagic THP-1 cells which were stimulated with lipopolysaccharide (LPS). LY30 selectively suppressed the mRNA expression of IL-12 p40, $TNF-{\alpha}$, and MCP-1 without affecting the expression of $IL-1{\alpha}$, IL-6, and IL-8. Inhibition of the production of IL-12 and $TNF-{\alpha}$ by LY30 was also demonstrated using ELISA assays. In order to elucidate the mechanisms of the action of LY30, we examined the role played by the mitogen-activated protein kinases and the key transcription factors, AP-1 and $NF-{\kappa}B$ in LPS-stimulated THP-1 cells. The results revealed that LY30 inhibited LPS-induced activation of ERK, but not p38 or JNK. Furthermore, the AP-1 DNA binding activity was suppressed by LY30 based upon the dosage, whereas $NF-{\kappa}B$ DNA binding was not affected. These results suggest that LY30 selectively inhibits cytokine production in the LPS-stimulated macrophagic THP-1 cells by down-regulating the activation of ERK and AP-1.

Stress is recognized as a major predisposing and/ or precipitating factor in long-lastig intractable chronic pain, such as temporomandibular disorders, headache, and other psychophysiological disorders. So it is necessary to detect physical and psychological changes induced by stress as soon as possible for positive treatment outcome. This study was performed to investigate the occurrence rate of stress symptoms according to anatomic region, type of symptom, and other personal and social factors. 859 subjects from general population answered the stress symptom questionnaire devised by the author and composed of 50 items. Data from the questionnaire were analyzed statistically with SPSS program and the results obtained were as follows : 1. Oral symptom which showed the highest frequency rate of 38.8% was vesicular lesion of the lip and cheek. The other symptoms with more 20% occurrence rate were ulcerative leion of lip and cheek, toothache, paresthesia of teeth, eruption of tongue, tongue coating and taste change in descending order. 2. In extraoral symptoms, ？데 disturbance was the item which showed the highest frequency rate of 62.0%, and the items for stiffness of suboccipital region and neck, headache, facial swelling, furuncle of face were answered more than 45% of the subjects whereas only 14.0% of the subjucts complained jaw pain under stress. 3. The better one who thought his or her health status was, the fewer items were answered and the difference of symptom frequency by dwelling place and by having hobby were shown in extraoral symptoms only. 4. For relief of stress symptoms, 79.2% of the subjects replied only to take a rest whereas not more than 13, 5% of the subjects visited dental clinic. Correlationship between symptom sites were very high.

The objective of this study was to propose a rehabilitation protocol for ankle fracture in Korean Medicine and to report its effectiveness. Four patients who had undergone ankle fracture by car accident were treated using the rehabilitation protocol in Korean Medicine. We estimated the outcome evaluating physical examination findings of the ankle joint, numeric rating scale, Olerud-Molander score, and walking state. After the treatment, we observed that ankle movement and muscular strength were improved. Moreover numeric rating scale, Olerud-Molander score, and walking state of patients were improved. A rehabilitation in Korean Medicine can be effectively used for ankle fracture patients. The limitation of this study was the insufficient number of cases. Further studies are needed to design a rehabilitation protocol in Korean Medicine.

The objective of preventive dentistry is the maintenance of a healthy dentition for the life of a patient. Unfortunately, if an individual has not received the benefit of a comprehensive program of preventive dentistry and has finally reached the edentulous state, as a consequence, he receives a set of complete denture. Dentures are mechanical devices and subject to the principles of mechanics. In some cases, the general health and nutritional status of the patient are felt to be the causative factors. But, the most important thing in residual ridge resorption is felt to be caused by the unequal distribution of functional forces. This study was to analyze mandibular stresses of complete denture occlusion by three dimensional finite element method. The results were as follows ; 1. As deformation and stress distribution of the complete denture of the mandible were concentrated on the upper lingual side of the mandible, alveolar ridge resorption of the mandible occurred from lingual side to labio-buccal side. 2. Analyzing by three dimensional F. E. M., the mandible is a very effective form for tolerating stress and deformation biomechanically. 3. According to the concentration of stress distibution in the upper buccal side of the lower posteriors, buccal shelf area must be a primary stress bearing area in the lower complete denture. 4. Lower complete denture moved horizontally to the balancing side under lateral occlusal force. 5. Bilateral balanced occlusion should be constructed in the complete denture for denture stability, especially in the protrusive movement. 6. Physical property of the denture base material was as important for stress distribution in the denture base as or even more than that in the mandible. 7. Impression technique is very important because of most of stress was concentrated between them due to close contact of the mandible and the denture base.

Background: A physically active lifestyle and regular exercise training incurs many health benefits. One recently recognized benefit of regular moderate exercise is stress reduction and immune enhancement. Thus, a physical stress such as exercise may act at any number of points in the complex sequence of events collectively termed the immune response. Although exercise causes many propound changes in parameters of immune function, the nature and magnitude of such changes rely on several factors including the immune parameters of interest; type, intensity, and duration of exercise; fitness level or exercise history of the subject; environmental factors such as ambient temperature and humidity. Methods: This study was undertaken to investigate the effect of different type of exercise on superoxide dismutase (SOD), neutrophils, and T lymphocytes of Sprague-Dawley rats. Sprague-Dawley rats were randomly divided into three groups; a non-Trained group (NTG, n=6), a swim-Trained group (STG), and a treadmill-Trained group (TTG). The exercise regimen was designed in a treadmill (5 times/5 days/week) during 8-weeks for TTG, and swim training (5 times/5 days/week) during 8-weeks for STG, and the volume of exercise training was the same in both groups. Results: 8 weeks of regular swim and treadmill training significantly increased liver SOD concentration however, muscle SOD concentration was not statistically significant. In the level of neutrophils, TTG and STG showed significant difference, compared to NTG. TTG was the highest level of neutrophils. In the level of immune cell counts, there was significant difference among TTG, STG, and NTG both in the spleen and thymus. Conculsion: In conclusion, it can be stated that eight weeks swim and treadmill exercise training has beneficial effect in improving immune response and antioxidant defence capacity by augmenting immune cells and SOD activities of SD rats.

In the present study, injuries in Taekwondo athletes during training and competitions was investigated via questionnaire. The purpose of this research lies in encouraging Taekwondo instructors and trainees to take precautions against injuries furnishing a variety of data obtained by analyzing the causes of injuries by region with ones undergoing a training. Understanding how frequently trainees get injured by region. we will be able to promote safety. which is such a meaningful move to improve training condition. The subjects of this study were 413 playes at the gym focusing on South Chungcheong province. Questionnaires for taekwondo players had the results as follows. The research reveals that physical injuries among Taekwondo athletes are caused by various reasons, regardless of sex and grade, and that the injures are repeatedly occurring, Therefore, in order t prevent and minimize the occurrence f injuries among Taekwondo athletes, not only the athletes but also trainers, business administrators, and educators need to pay careful attentions and take necessary measures accordingly. Also, pre-education on precaution against injuries must be put into practice thoroughly and an environment in which the inured could receive swift first aid treatment as well as follow-up measures shall be formed. this, in the end, is expected to contribute in improving not only the health of the athletes but also their performances in matches.
