Occupational health services in Korea have been operated as dual types : one is operated by occupational health care manager and the other is health care agency without their own personnel. The performance of occupational health service should be different due to the variety of characteristics of health care manager and workplace, qualification of health care manager. This study is to analyze performance of occupational health care services with a particular consideration of job performance shape and efficiency, based on comparing those two types of health care management to show on the basic data for the settlement of more qualitative health care management system at workplace. For this study, total 391 places in Seoul and Inchon city area ; 154 places (39.4%) managed by designated health care manager and 237 places (60.6%) by the agency with their commission are selected as research samples. Tools for data collection are questionnares that have been investigated during the period of 20 September 1993-20 December 1993. Those data are compared with percentiles, mean, standard deviation and B/C ratio using SPSS PC program. Conclusions observed from the tests and each comparison could be summerized as follows : 1. Occupational health care have been accomplished at workplaces with designated people than with agencies people, and coverage rate of the occupational health care services has differences, due to management types. The reason of these results is due to visit only one or two times monthly by the agencies, while their own health care manager obsess, at the workplaces all the times. 2. Most of the expense for environmental control of all health care services expenditures shows that there is almost no fundamental improvement because more expenses are needed for procuring personal protective equipment and measuring work environment instead of environmental improvement. 3. It is investigated how much the cost of occupational health care services needs per worker, and calculated how much the cost needs per service hour per worker. The results from this show that the cost of occupational health services at workplaces with their own managers used less than the cost of health care agencies, eventually the former gives better services with less cost than the latter. 4. Benefit/Cost ratio is also produced by total benefit/total cost. The result from the above way reads 4.57 as a whole, while their own manager having workplaces reads 4.82 and the agencies do l.56. Even if their own manager performing workplaces spent more cost, this system produces more benefit than the agencies management. 5. The B/C ratio for medical organization such as local clinic, health care center and pharmacy shows more than or equal to at the workplaces controlled by the agencies. It is inferred that benefit would be much less than the cost used, with so being inefficient. 6. It is assumed that the efficiency ratio of health education is equal to reduction rate of workers medical organization visit. Estimated reduction rate 5%, 10%, 15%, show that the efficiency ratio of health education have an effect on producing benefits. It is estimated that more benefit can be produced if more qualitative education will be provided for enhancing health care efficiency. 7. Results of this study cannot be generalized because there are large scale of deviation in case of workplaces with less than 300 full time workers, but B/C ratio reads 2.69 as a whole and 3.25 at workplaces with their own health care manager are higher than 1.63 at the workplaces manged by the agencies. Finally, all the benefit concerning health care services could not be quantified, measured and shown on the value of money. This is a reason that a considerable part of benefits are so underestimated. This is also thought that measurement tools should be developed for measuring benefits of health care services with a comprehensive quantification. in the future. It is also expected that efficiency of occupational health care services should be investigated using cost-effectiveness analysis.

Purpose : To evaluate the incidence of arm morbidity following breast cancer surgery including axillary dissection and to identify related factors. Materials and Methods : One hundred and fifty nine patients were studied using a self-report questionnaire and a clinical examination. Lymphedema, reduction of range of motion in shoulder joint and subjective symptoms (pain, impaired arm movement, numbness, stiffness) were evaluated. As related factors, demographic, oncologic characteristics and types of treatment were analysed. Results : The incidence of lymphedema ($\geqq$2 cm difference comparing to unaffected arm) was $6.3\%$, $10.7\%$, $22.5\%$ and $23.3\%$ at each 10 cm, 20 cm, 30 cm, and 40 cm from wrist. Reduction of range of motion in shoulder joint ($\geqq$ 20 degree difference comparing to unaffected arm) was noted In more than 1/3 patients for flexion, abduction and internal rotation. Especially the reduction of range of motion in internal rotation was severe ($>50\%$ reduction) in 1/3 patients. Approximately 50 to $60\%$ of patients complained impaired arm movement, numbness, stiffness and pain. Body mass index (BMI) was the significant risk factor for lymphedema. Conclusion : Lymphedema was present in 1/3 of patients and the common sites of edema were 30 cm 40 cm proximal from the wrist. Also most severe reduction of range of motion in shoulder joint was with internal rotation. There needs weight control for lymphedema because BMI was the significant risk factor for lymphedema. Also rehabilitation program for range of motion especially internal rotation In shoulder joint should be developed.

The effects of noise exposure are of two types: Nonauditory effects and auditory effects. Nonauditory effects of noise exposure are interference with communication by speech, sleeping and emotional behavior. The noise will cause the high blood pressure and rapid pulse, also that decrease the salivation and gastric juice. in experimentaly showed that the Corticoid hormon: Gonatotropic hormone were decrease and Thyrotropic hormoone is increase. Auditory effect of noise exposure. when the normal ear is exposed to noise at noise at hamful intensities (above 90㏈) for sufficiently long periods of time, a temoral depression of hearing results, disappearing after minutes or hours of rest. When the exposure longer or intesity greater is reached the Permanent threshold shift called noise-induced hearing loss. Hearing loss resulting from noise exposure presents legal as well as medical problems. The otologist who examines and evaluates the industrial hearing loss cases must be properly informed, not only concerning the otologic but also about the physical and legal aspects of the problems. The measurement of hearing ability is the most important part of a hearing conservation, both preplacement and periodic follow-up tests of hearing. The ideal hearing conservation program would be able to reduce or eliminate the hazardous noise at its source or by acoustic isolation of noisy working area and two ear protections (plugs and muff type) were developed for personal protection.

On the ArcGIS 9.2 program in Gyeongsangbug-Do and Daegu areas, distribution ratios of rock types and geologic ages were obtained from the 1 : 250,000 scaled digital geologic and geomorphic maps. The obtained distribution ratios here will be used the geologic information data for industrialization and development planning of rock resources. The Gyeongsangbug-Do area consists of 86 rock types that can be divided into 10 large groups in geologic age. Their geologic distribution ratios show the decreasing in the order of Cretaceous, Precambrian, Jurassic, Quaternary, Age-unknown and Tertiary, all of which occupy the prevailing ratio of 96.30% in the area. Of which, sixteen rock types are somewhat dominant ones (64.04%). They are of Precambrian Yulri group and granite gneiss of the Yeongnam metamorphic complex and biotite gneiss of the Sobaegsan metamorphic complex, Age-unknown granite, Jurassic granite, Cretaceous Gasongdong and Dogyedong formations of the Yeongyang sub-basin, Nagdong and Chunsan formations and intermediate-basic volcanics of Euiseong sub-basin, Jinju and Jindong formations and andesite-andesitic tuff of Milyang sub-basin, and hornblende granite, and Quaternary alluvium. They show relatively narrow ranges of 2.07-6.53% in geologic distribution in exception of Jurassic granite showing 13.14%. And the rest 70 rock types appear to very narrow range between 0.01 and 1.94 %. On the other hand, twelve rock types are developed in the Daegu area. Their geologic ages appear to be classified into Cretaceous and Quaternary occupying 86.05% and 11.39%, respectively. Seven rock types take possession of 94.04% among the all rocks. The major rock types are Jinju formation of the Sindong group, Chilgog, Haman and Jindong formations of the Hayang group, andesite and andesitic tuff, hornblende granite and Quaternary alluvium. With exception of andesite and andesitic tuff of 37.40%, the types show slightly wide range of 3.25-17.39%, which apparently differ trends from that of Gyeongsangbug-Do area. And the rest of rock types have narrow ranges of 0.22-1.81% in the Daegu area.

The study was conducted to provide data for the development of effective medical conflict prevention programs for dental hygiene by analyzing the dental experience conflicts. A self-administered questionnaire survey was conducted targeting dental hygienists who were performing dental assistance at university hospital, dental hospital and dental clinic in Busan and Gyeongnam regions from April 1 to 30, 2014. Collected questionnaires of 212 dental hygienists were then analyzed with IBM SPSS Statistics ver. 20.0 program. A total of 59.4% had experienced complaints, discontents and medical disputes and 24% of these had experienced a legal trouble developed from such and 95.3% were anxious and doubtful about a possible future medical dispute to some degree. Patient complaints, complaints of non-medical issues raised by 24.3% was the most common, notices, maps and descriptions in relation to the issues raised by 14.4%, is related to the impression issue was raised in the order of 13.5%. Occurrence of disputes did not show a significant difference by place of work, however, a possibility of development of dispute into a legal proceeding showed a significant difference depending on service career and it was investigated that the experienced group feels more pressures with regard to a medical dispute according to their experience of such. All respondents said that education on a prevention and countermeasures of medical disputes is necessary. Understanding of dental hygienists on medical related laws regarding the scope of duty is required to be enhanced and, in order to do so, opportunities to receive an education with regard to a prevention and countermeasures of medical disputes are to be expanded.

The aim of this work was to establish the optimal conditions for the production of cellobiase by a marine bacterium, Cellulophaga lytica LBH-14, using response-surface methodology (RSM). The optimal conditions of rice bran, ammonium chloride, and the initial pH of the medium for cell growth were 100.0 g/l, 5.00 g/l, and 7.0, respectively, whereas those for the production of cellobiase were 91.1 g/l, 9.02 g/l, and 6.6, respectively. The optimal concentrations of $K_2HPO_4$, NaCl, $MgSO_4{\cdot}_{7H2}O$, and $(NH_4)_2SO_4$ for cell growth were 6.25, 0.62, 0.28, and 0.42 g/l, respectively, whereas those for the production of cellobiase were 4.46, 0.36, 0.27, and 0.73 g/l, respectively. The optimal temperatures for cell growth and for the production of cellobiase by C. lytica LBH-14 were 35 and $25^{\circ}C$, respectively. The maximal production of cellobiase in a 100 L bioreactor under optimized conditions in this study was 92.3 U/ml, which was 5.4 times higher than that before optimization. In this study, rice bran and ammonium chloride were developed as carbon and nitrogen sources for the production of cellobiase by C. lytica LBH-14. The time for the production of cellobiase by the marine bacterium with submerged fermentations was reduced from 7 to 3 days, which resulted in enhanced productivity of cellobiase and a decrease in its production cost. This study found that the optimal conditions for the production of cellobiase were different from those of CMCase by C. lytica LBH-14.

The purposes of this study were 1) to analyze the preference of leadership style among ${\lceil}$Transformational leadership$\rfloor$ and ${\lceil}$Service leadership$\rfloor$, 2) to examine the differences of the job satisfaction between the high level of service leadership group and low level of the service leadership group and 3) to testify the hypothesis that the service leadership and its 4 elements (belief, attitude, ability, insight) affect the job satisfaction. The questionnaires were developed to measure the service leadership, the preference of leadership style (transfer-mational leadership and service leadership) and Job satisfaction. The surveys were distributed to 120 managers and employees in the family restaurant in Korea, and 104 questionnaires were responded (response rate: $86.7\%$). The SPSS 12.0 package program was used to conduct the descriptive analysis, correlation analysis, t-test and multiple regression analysis. The result of leadership style preference showed the followers preferred the service leadership $(75.0\%)$ to the transformational leadership $(25.0\%)$. Comparing the job satisfaction of high level of service leadership group and that of low level of service leadership group, the job satisfaction of high level of service leadership group was significantly (p<0.001) higher than that of low level of service leadership group (high level of service leadership group: 4.03, low service leadership group: 3.27, measured on a 5-point likert scale). All three factors of job satisfaction (human factor, service system and company image) in high level of leadership group were significantly (p<0.001) higher than those of lower level of service leadership group. The result of multiple regression analysis presented that the service leadership and it's 4 elements (concept, mind, skill, insight) have significant (p=0.000) effects on the job satisfaction. As a conclusion, we examined theoretical framework of service leadership model and testified the applicability in the field of family restaurants. But the service leadership was the new conceptual theory, so there should be the more empirical studies on managers and employees in the service industry.

The purpose of this study was to assess the provided home health care services and to evaluate the patient's satisfaction level of received home health care services. Well trained two home health care nurses interviewed with 138 respondents who received home health care by Keimyung University Hospital from January 1st to August 31st 1999. The results were summarized as follows : 1) Among 138 respondents, $55.8\%$ were mail and $44.2\%$ were female and $70.3\%$ of them were over sixty years old. Respondents main family care givers were spouse$(53.6\%)$, daughters and sons$(36.2\%)$ and parents$(7.2\%)$. 2) $60.2\%$ of cancer patients received home health care services, $23.3\%$ of cerebral­cardiovascular patients, $7.5\%$ of endocrine disorder patients, $2.3\%$ of those who have indwelling foley catheter patients, $1.5\%$ of those who have respiratory problems and others$(5.2\%)$. 3) $88.1\%$ of respondents were satisfied with the number of home visits they received. $50.5\%$ of respondents' were received 1 to 3 times of home visits by home health care nurse per month. $48.6\%$ of respondents answered they were introduced by attending doctors or nurses to home health care services. $55.8\%$ of respondents answered registration to home health care services was simple and easy. $97.4\%$ of respondents answered home health care payment system was adequate. $64.9\%$ of respondents answered the cost of home health care per visit was adequate and comfortable. 4) Health education, counselling, physical assessment was provided to most of the patients. Those who suffered with cerebral-cardiovascular disease was needed hands on direct care most of all. The least home health care service provided was medication. 5) The satisfaction measurement tool was composed with 13 items and 3 score scale. The mean score of satisfaction on provided home health care services was 2.67 out of 3. Among 13 items. 'home health care service was kind enough' was highest(2.84). 'nurse use precise word to understand and communicate'. 'nurse gave home visiting notice ahead of time and kept the home visiting promise on time' was 2.83. 'whenever I need home health care nurse I can give a call and meet the nurse' was lowest 2.41. Special Home Health care programs such as comprehensive hospice care programs for elders over sixty years old should be organized. Adequate and standardized home health care payment system should be developed as soon as possible. In korean family situation. when family members are getting sick and stay at home. family members were taking care of the patients. special program such as counselling family members are needed.

Maternity means all the women who are capable to conceive. In the aspect of health and medical care. however. it means the women who are now in pregnancy or have already given birth to a baby or are in a period of being recoverd from physiological changes occurred by pregnancy. According to the rapidly changing social structure. both the Quality and Quantity of the capacity of childbirth experienced by women are changing. Our society. having established a great economical growth by virtue of the highly developing and growing industrialization and urbanization. stimulates the women's advance into society and thereby increasing the number of employed women. When the women's participation in society is increased. their age of marriage is also affected. Which means there are a decrease of the capacity of childbirth in terms of quantity and a trend for women to have less children and to deliver a baby in their old age in terms of quality. On the contrary. since the number of multipara who want to have a baby in their old age is increasing. as a counter functional effect to the political project of decrease of a birth rate. concern has been focussed on childbirth in old age in the present study. And also such kind of the childbirth may be danger to the health of both mother and baby. Therefore the present study intended to provide some basic data of health education in the part of the health management of both mother and baby in the general hospital. based on understanding the realities of childbirth in. old age and things related to them. To achieve such a purpose of the present study. an analytical study by means of SPSS. was done using the data of 269 clinical records on both the newborn .babies and their mothers who had been supported by public general hospitals located in Seoul for 3 years from Jan. 1. 1991 to Dec. 31. 1993. Some significant results from the analytic study are as follows: 1. It appeared that the average age of normal. natural delivery was 33.8 years old and the average age of delivery through the cesarean operation was 35.4 years old. 2. It appeared that danger factors to childbirth women were types of the delivery and placental extrusion and danger factors to newborn babies are not so outstanding. 3. It appeared that the variables of the childbirth capacity which showed a significant difference according to each age group of women were the number of pregnancy. number of still birth, and number of existing children. That is. the age group of 'more than 35 years' had more frequency of experience In all 3 variables than the age group of 'less than 35 years'. 4. It appeared that the variables of the childbrith capacity which showed a significant difference a according to the sex of a newborn baby were number of pregnancy, number of still birth, and number of existing children. That is, the age group of 'more than 35 years' had more frequency of experience in all 3 variables than the age group of 'less than 35 years'. 5. It appeared that the health index of newborn babies which showed a significant difference was only 5 minute APGAR. That is, the health index 9.46 in the age group of 'more than 35 years' was less than an index of 9.72 in the age group of 'less than 35 years'. 6. Since a counter correlation of -0.10, as Pearson Correlation Coefficient, was showed between the age of childbirth mothers and the weight of newborn babies, it indicated that the higher age of childbirth woman, the lesser the weight of newborn baby. 7. It appeared that the number of women who had confirmed the sex of their baby before their delivery were 45 women, $67.2\%$ of total 67 women who had delivered a baby. and the expected sex by women in childbed was male with $73.1\%$ of total childbirth women expecting male birth and with their expression of feeling of female delivery. very regretful' by $39.3\%$ of total childbirth women. The results as shown above may indicate that instead of the possibility of danger to both the mother delivering a baby in old age and the baby delivered, the expectation of getting a son motivates childbirth in old age. As a conclusion, in a dimension of general hospital as well as national reform. it is required that a program of health education for childbirth in late maternal age have to be developed in the part of the health management of both mother and baby in the near future.

Most hospitalized children will experience physical pain as well as psychological distress. Preschool children's pain perception related to painful procedures can increase due to elevated anxiety and fear because they do not have understanding logical of their disease and hospitalization. In particular, they are distressed about needle - related procedures which are feared because they are seen to be a cause of bodily damage. This descriptive study attempted to identify pain perception levels in preschool children and their mothers. A self-reporting measurement and behavioral observation were used to collect the data. A total of 25 hospitalized preschool children and their mothers were investigated and data were collected about 60 painful procedures. Data collection was carried out by the researcher and two trained investigators from November first to December tenth. Three insruments were used to collect the data : Faces Pain Rating Scale(FPRS) developed by Beyer was used to measure the degree of preschool children's pain perception about painful procedures. The Visual Analogue Scale(VAS) devised by Huskisson was used to assess the degree of mothers' pain perception about their children's painful procedures. A Pain Behavioral Checklist based on the Procedure Behavior Check List by LeBaron and Zelter and modified by the researcher was used to observe behaviors of preschool children, their mothers, and nurses when the painful procedures took place. The data were analyzed by an SPSS program, and were tested using real numbers, percentages, Pearson correlation coefficient, t-test, and ANOVA. The results of this study are as follows : 1. Of all the painful procedures, the mean score for the FPRS for the preschool children's pain perception was 4.02 points, and the mean score for the VAS of mothers' pain perception was 10.92 points. 2. A Positive correlation which was statistically significant was found between the pain perception of preschool children and their mothers (r＝.53, p＜.01). that is, the higher the children's pain perception was, the higher their mothers' pain perception was. 3. The characteristics of the painful procedures related with children's pain perception as follows : The type of painful procedure was found to be statistically significant (F＝23.44, p＜.01), Among the three procedures Ⅳ starting was found to be perceived as the most painful procedures to the children. The greater the number of times that the procedure had been done, the higher the pain perception was (F＝4.44, p＜.01), and the longer the duration of the procedure, the higher the pain perception wa(r＝.30, p＜.05). Pain perception in the treatment room was higher than in the children's room(t＝6.30, ＜.01), pain perception in the mother's presence was the higher than when the mother was not present (t＝2.91, p＜.01). 4. The characteristics of the painful procedures related with the mothers' pain perception as follows : The type of painful procedure was found to be statistically significant(F＝6.01, p＜.01). Among the three procedures Ⅳ sampling was found to be perceived as the most painful procedures to the mothers. The greater the number of times that the procedure had been done, the higher the pain perception was (F＝5.95, p＜.01), and the longer the duration of the procedure, the higher the pain perception was (r＝.31, p＜.05). Pain perception in the treatment room was higher than in the children's room (t＝3.51, p＜.01), but pain perception in the mother's presence showed statistically significant no difference. 5. Of all of the 19 children's behaviors during the painful procedures, the most frequent behaviors observed Were as follows in order of frequency “crying”, “screamirig”, “facial grimacing”, “physical resistance”, Of all of the nine methers' behaviors, the most frequent by observed in “console children”, “hold children”, “applaud children”, Of all of the 11 nurses' behaviors during the painful procedures, the mast frequent in order were “smiling”, “physical restraint”, “console children”, “praise children”. 6. A positive correlation between children's and mothers' pain perception and children's behaviors was found to be statistically significant (r＝.65, p＜.01, r＝67, p＜.01). Also the relationship between children's and mothers' pain percertion, and mothers' behavior was found to be statistically significant (r＝.57, p＜. 01, 4＝.60, p＜.01). The relationship between children's pain perception and nurses' behaviors was also found to be statistically significant (r＝.46, p＜.01), but there was difference between mothers' pain perception and nurses' behaviors.
