Occupational hearing loss became the leading occupational disease by constioution 56% of all work-related diseases in Korea. However, the prevalance rates showed wide variations among the specific medical examination providers and were very low(0.8-1.4%) compared with those 8.4% in Japan. The sources of these variations was regarded in the preview study as 1) Employee audometric estings were primarily conducted by nurses and nurse-aids who had no formal training for audiometry; 2) althought audiometric testing equipment used by the spedific medical examination providers, it should be periodically calibrated, a significant number of them were not properly calibrated : 3) Initial audiometric testings were conducted at any available spaces in workplace or at the testing room without considering bachground noise level. One of solutions that can be done for sloving surrent noise related problems is to provide a noise related manual for the occupational health managers including doctors, nurses and hyginests. This study was done to provide such a manual. The main core of the manual was hearing conservation program. And the contents of the manual was the same as the main frame of hearing conservation program such as noise survey, provided of the diagram showing the core contents of each factor of the hearing conservation program. Hopefully, this manual will be the references of the standardized performances of the specific medical examination providers.

Purpose : To evaluate the impact of added progestogen on biochemical markers of the bone turnover undergoing hormone replacement therapy in the postmenopausal women. Materials and Methods : There are 71 postmentopausal women who are divided into three groups (Group I, Group II, Group III). Group I(continuous combined)is given conjugated equine estrogen (CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate (MPA, 2.5mg, day 1-30), Group II(unopposed estrogen) is given conjugated equine estrogen (CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate (MPA, 5mg, day 1-12). And there were measured serum osteocalcin, serum total alkaline phosphatase and urinary deoxypyridinoline excretion before starting hormone replacement therapy and 12 months later. Results : The serum osteocalcin, serum total alkaline phosphatase and urinary deoxypyridinoline excretion significantly decreased after hormone replacement therapy (Group, I, II, III). And there was no significance in decreases in biochemical markers of the bone turnover among three groups. Conclusions : It was concluded that the impact of added progestogen on the biochemical markers of the bone turnover undergoing hormone replaced therapy in postmenopausal women was not significant than nothing added group. Thus we concluded that progestogen was not impact on decreasing on the biochemical markers of the bone turnover in postmenopausal women undergoing hormone replacement therapy.

The impact of cancer on human life has been recognized and the demand for care for the patient with cancer is ever increasing. Yet very little study around these concerns has been reported. The subjects of this study were 388 patients with cancer who were receiving treatment .in the outpatient department of Yonsei University Cancer Center. The study dealt with the health problems experienced while receiving this treatment. The research method used in this study was the structured interview technique using a questionnaire. Data collection was done between Dec. 1. l986 and June 30. 1987. The questionnaire used in this study was a revision of three questionnaires, one developed by D.W. McCaffrey(coping with cancer), one developed by C.A. Morris(self concept as altered by the diagnosis) and one developed by M.J. Yasko(management of symptoms associated with chemotherapy). Content validity was treated with oncologists and oneology nurses & nursing faculty members. The results and recommendation of the study areas follows: 1. Results. 1) Characteristics of the Sample The diagnoses of the subjects were as follow: The most frequent diagnosis was cancer of the stomach(26.5%), followed by breast cancer, lymphoma, rectal / colon cancer and lung cancer. The average age was 48.6 years. There were an equal number of men and women. There were 116(30.4%) subjects who received chemotherapy and surgery for the treatment of their disease of the total number of subjects. 264(69.5%) were treated for less than 1 year, and 116(30.5%) were treated for more than 1 year. The average Length of treatment was 12.7 months. 2) In Summary Health problems were categorized under four areas: physical. emotional, social and economical. The patients with lymphoma and stomach cancer experienced more health problems than any others in this study. According to the age of the patients, those in their 20's complained of physical and emotional problems most frequently and of those in their 30's social-economical concerns were most evident. In female gender. physical and emotional problems were identified more frequently than male patients. And yet male patients indicated greater concern with economic problems than female patients. Regardless of the treatment method or length of treatment health problems in different areas were similar and statistically not significant. However, economic concern was statistically significant(F = 2.52. p< 0.5) in those with receiving a combination of chemotherapy and radiation Marital status and health problems were also statistically significant. That is patients who were divorced, separated or widowed had more physical, psychological and economical problems than those who were married. 2. Recommendations. 1) Since the physical symptoms of nausea / muscle weakness and malnutrition were major health problems, the patient's diet and activity need to be carefully detailed and included in the care plan and further research is needed in order to implement physical, psychological. economical & spiritual interventions. 2) A follow up study should be done using a larger number of subjects and indifferent settings to further validate the health problem checklist for cancer patients.

The aim of this study was to assess the nutrient intakes of the elderly subjects in Korea. Dietary assessment was carried out using a semi-quantitative food frequency questionnaire (SQFFQ) developed by our laboratory, which included 98 commonly consumed food items selected from 1998 National Health and Nutritional Survey for Korean population. Subjects (n = 2,660) aged 50yr and over were recruited in Seoul, 6 metropolitan cities, and 8 mid-size cities. Calcium and riboflavin intakes of the elderly subjects aged 65 yr and over (n = 1,974) were much lower compared with Korean RDA. Nutrient intakes of the three age group (50 - 64 yr, 65 - 74 yr, 75 yr and over) were decreased as age increased in male and female elderly. Nutrient intakes of male elderly, 75 yr and over, were significantly decreased while in female elderly nutrient intakes were gradually decreased as age increased. Over 30% of the elderly subjects did not meet 75% RDA for calcium, iron, vitamin A, and riboflavin. The proportion of the elderly subjects whose intakes were below 75% RDA was much higher than the elderly whose intakes were above 125% RDA, especially among the elderly aged 75 yr and over. This study revealed that the Korean elderly had inadequate intakes for many nutrients. This will cause a serious nutritional problem for the elderly.

레빈이론의 분석 및 평가

In Levine's theory of nursing, nursing is human interaction. This is based on the idea that people are dependent on their relationships with others. The nurse has the responsibility to intervene in the patient's situation after recognizing the patient's organismic response. Nursing Interventions are supportive(maintain the status quo) or therapeutic (promote healing and restoration). The nurse's interventions are based on the four conservation principles. These are : (1)conservation of energy (2)conservation of structural integrity (3)conservation of personal integrity, and (4)conservation of social integrity. These conservation principles provide a guideline for viewing the individual in a holistic manner. Levine's theory does relate to the concepts of individual, society/environment, health, nursing, and to the nursing process. The person is holistic and adaptive. Levine's environment is whenever the nurse and the patient interact : nursing centers around the use of the scientific method and the provision of holistic care. Health means whole and encompasses aspects of adaptation. Levine's model has internal and external consistency, has added a great deal to the overall development of nursing knowledge. Also, Levine's theory for nursing is compatible with the practice of nursing in an acute care setting and home health care. But Levine's theory for nursing focuses on one person - the patient, it can't be used in working with families, groups, or communities and it may offer some limitations when used in areas where the focus is on long-term care and rehabilitation. Because it focuses on the individual and patient's dependency. Although there are various nursing theories, we don't have consistent nursing model. There are many problems to analyze and evaluate the nursing theory by evaluation criteria of any one person. But we must try to continue to analyze and evaluate nursing theories, refine the nursing model to adapt to reality, and generalize it through the adaptation in the clinical practice, community nursing setting.

MIMO 시스템에서의 APP 디코딩의 성능

이경규,김산해,김홍철,이원철,신요안 崇實大學校 生産技術硏究所 2002 論文集 Vol.32 No.-

MIMO (multi-input multi-output) systems can achieve high data capacity and high data rate in the third generation (3G) or beyond-3G mobile communication systems. To effectively improve the performance of MIMO systems, new detection schemes which can mitigate mutual interferences from multiple transmit antennas, are highly required. In this paper, we consider a posteriori probability (APP) type detection schemes for the MIMO systems, and compare with other sub-optimal detection schemes based on zero forcing (ZF) and minimum mean square error (MMSE) - ordered successive interference cancellation (OSIC). Simulation results show that the APP outperforms ZF-OSIC and MMSE-OSIC, while the performance discrepancy becomes smaller as the number of receive antennas increases.

Objectives : Diffusion tensor imaging (DTI) is a new technique that can be used to visualize and measure the diffusion of water in brain tissue. It is particularly useful for evaluating white matter abnormalities. In this paper, we investigated the neuropathology of the corpus callosum in patients with schizophrenia through the new methods, diffusion tensor imaging. Methods : Diffuse tensor imaging was performed in 19 schizophrenic patients and 26 healthy controls. One complementary measure, fractional anisotropy (FA), which is considered to be sensitive indices of axonal integrity, was obtained from regions of interest in the five areas of the corpus callosum. Neuropsychological measurement also underwent for measurement of frontal lobe function in two groups. Results : There were no significant differences of FA in the DTI measures for either the schizophrenic patients compared with controls. FA was significantly decreased in women compared with men. Neuropsychological measurements such as Wisconsin card sorting test were correlated with FA of patients with schizophrenia. Conclusion : FA measures revealed no differences between schizophrenia and controls. The findings suggest that the structural integrity of white matter in patient with schizophrenia was not disrupted. The results are discussed in relation to previous studies reporting positive and negative findings. It is concluded that further studies using DTI in larger samples, improved and standardized methods of data acquisition and analysis are needed.
