During the period of 1964 to 1972, epididymovasoetomies were performed on 53 cases of azoospermias due to epididymal obstruction. They were operated by the technics of the ordinary side-to-side epididymovasostomy with splint, in such a manner that a minute longitudinal opening in the vas was anastomosed to a similar opening in the epididymis at a site where live sperm had been recovered, which was applied on 58 per cent of the subjects, and of the buried side-to-side anastomosis with a splint, wherein longitudinally opened vas ..was actually buried in longitudinally opened head of epididymis, which was attempted on 26 per cent of them. The following data are presented as abstraction of clinical findings and the operation outcomes: l. An average age of the subjects was 35, and that of their wives, 30. 2. An average duration intervening between the beginning of the obstruction and the performance of the operation was 9 years. 3. An average frequency of sexual intercourse per week indicated 2.5 times before the obstruction 2. 2 times after the obstruction, and 2. 1 times after the operation. 4. In the majority of the cases, the post-inflammatory obstructions were found to be the most responsible causes for azoospermia in my present study. That is, non-tuberculous epididymitis (gonorrheal and non-gonorrheal origin) was found in 70 per cent of the subjects and tuberculous origin, 25 per cent of them respectively. 5. Success rate of non-tuberculous epididymitis group is higher than that of tuberculous epididymitis counter part 6. Success rate of the buried technic group is higher than that of the ordinary technic group. 7. Success rate of bilateral oozes with sperm group is higher than that of unilateral oozes with sperm or no oozes group. 8. A total of 53 cases was operated upon for curing the obstructive azooepermias. Poet-operative semen analyses were carried out on 43 cases out of the 53. Sperm appeared in the ejaculates of 17 cases out of the 43 in repeated sperm tests 3 weeks following the operation. Accordingly, successful operations were showed in 40 per cent of the 43 cases. Seven pregnancies(16%) followed the operation. 9. The writer believes that epididymovasostomy could be said to be a worthwhile procedure for the cases of asooapermia due to the obstruction of globus minor with normal spermatogenesis. The prognosis is always good whenever the indications are strictly followed.

Death is the critical moment of life. All elderly are faced with death. Therefore, the elderly's notion of death must be include in holistic care for the elderly. The purpose of this study was to understand the elderly's notion of death. The research questions were "What is the elderly's notion of death?", and "What is the embedded meaning of the elderly's notion of death?". This study was conducted using an ethnographic approch. The fieldwork for this study was done from July 1996 to July 1998 on an island in Chonbuk province. Data were collected by indepth interviews and participant observation. The result of this study is as follows The elderly's notion of death was founded on 'Being a ancestor god', 'Evaluation of one's own life', 'Be sujected to the evil(BuJung : the taboo of uncleanness)' 'Being a ancestor god' means the notion of death leading to eternal life. It means a relationship to this world, So, it is required for all descendants, especialy the son. Also, they thought that the Spirit is greater importance mote thait the body, and that the spirit is embedded in bone. And so, the spirit is delivered to descendants through a propitious site for grave(MoungDang). It is thought toa change in the fortune of the descendants(Balbok). 'Evaluation of ons's own life' means that life was evaluated personally and socially throughout the dy ing process. This means reflection on an individual's life and interpersonal relationship's, and appearance social aspects of the individual death. 'BuJung(be subjected to the evil)' emerged as fear about death, and pursuit of the cause of death, Most of the causes were attributed to supernatural entities. It contributed to the inspiration of a cornmunity identity. The elderly's notion of death was the present world oriented and actualized. This study contributed to the nurse's understanding of the Korean elderly's notion of death. Implications for nursing practice, education, and research were discussed. Further research at other settings and using other research methods were recommended.

Melanogenesis, or synthesis of melanin has been a focus of intense investigation by pigment cell biologists during the past few decades. Melanogenesis provides pigment in skin, thus serving as a unique, if not only, physiological defense against sun-induced injuries, including photocarcinogenesis. Moreover, skin color plays a major role in visual esthetics of an individual. Therefore, unwanted hyper- or hypo-pigmentation, especially on facial skin, could cause significant psychological stress. Epidermal melanocytes, derived from neural crest cells, are mainly responsible for melanin in skin. In human skin, nearly all normal pigmentation is due to melanin and with the exception of hemoglobin, it is one of the only endogenously synthesized pigments in man. Melanin has numerous functions in mammals, including increasing the optical efficiency of the eye, producing color patterns in various organs, including hair or skin, serving as camouflage, heat exchange, sexual recognition and protection from sunlight. The incidences of malignant melanoma have been increasing dramatically in western countries, at least by a factor of 15 over the past 60 years, and this has caused an intense interest in understanding melanogenesis. More than 40,000 new cases of malignant melanoma have been diagnosed in 1997, and it is one of the most common cancers in young adults. The research in the area of melanogenesis has exploded during the last ten years because model systems to study molecular mechanisms regulating melanogenesis have become available. This review examines currently available in vitro and in vivo model systems to study melanogenesis.

Congenital dislocation of the hip has always presented an unique problem in Orthopedic Surgery. Orthopedic surgeons have been baffled not only by the mystery of its origin, but also by its unpredictable course and the uncertainty of results of treatment. Hippocrates described this condition first with all its distinguishing characteristics, including distortion of the hip, the pathologic gait, the exaggerated lordosis. etc, His prognosis in this luxation of early childhood appeared to be unfavorable. In 1895, Lorenz established a new, decidedly conservative method of treatment. His process involved a complete separation of the two objectives to be fulfilled, namely reduction and retention. To retain this reduction he conceived the motion of fixing the hip for a specific and prolonged period in carefully chosen “primary position” of 90 flexion and 90 abduction by forcibly maintaining the head in its normal location. Ortolani, in 1935, was the first to show that a diagnosis could be establisted immediately after birth. The jerk, click or snap elicited by manipulation of the new born infants hip. Early diagnosis is still the most important aspect of congenital disiocation of the hip. Despite the emphasis on early diagnosis, a disturbingly large number of congenital dislocation of the hip remain undiagnosed until after the child has started to walk. Numerous surgical procedures and modifications have been used. The general types are: 1) Open reduction, 2) Shelf procedure, 3) Innominate osteotomy, 4) Arthroplasty, and 5) femoral osteotomy. These procedures have been useful also with the more difficult problem of residual or recurrent dislocation or subluxation aftertreatment by closed or open method. Congenital dislocation of the hip was not common in Korea like as in western countries. The reasons for this are poorly understood. But racial differences and native customs may offer a partial explanation. The author studied congenital dislocation of the hips in sex incidence, site of predilection, clinical symptoms and signs, X-ray findings, relation to the congenital anomalies and birth history, and the results of treatment. In this study, 57 cases of congenital dislocation of the hip, admitted to the orthopedic department of Severance Hospital during 7 years and 6 months since January 1963 until June 1970, were reviewed. The results of this study are as follows: 1. The annual changes of the numbers of the patients, who were first seen at Severance Hospital, were increasing. 2. The female incidence in Korea is relatively low as compared with the western countries. And the preponderance of females over males is in the ratio of ten to one in bilateral cases and two to one in unilateral cases. 3. The ratio of bilateral cases: right sides: left sides is 1:2: 2.2. 4. In these series, 15 cases of congenital anomalies or diseases in 13 patients are combined and among them, 10 patients are included in teratologic groups. And most common co-existing anomalies are club foot (7 cases). The incidence of the teratologic dislocation in Korea is relatively high as compared with the western countries. 5. The acetabualr index in affected hips showed no relationship to the age factor, but C-E angle, Y-coordinate and height are aggravated according to the increment of age. 6. Closed reduction is satisfactory under the age of 3, but after then the prognosis is poor. 7. Open reduction is recommendable after the age of 3 and under the age of 9. 8. The prognosis of treatment in bilateral cases and teratologic groups is poor.

Although a family-centered approach to health care for developmentally disabled children has been advocated, existing systems of care have not adequately addressed the support needs of the family system and the essential role that parents play in the daily care of these children. The overall purpose of this research is to examine family system adaptation to the care of a developmentally disabled child using the Resiliency Model of Family Stress, Adjustment, and Adaptation Framework. Relationships among family system demands(stressors, strains, transitions, child's illness factors) and family system strengths and capabilities(resource of social support) were examined to determine their separate and combined contribution to explaining the variability inn family system outcomes(family system coping). The subject for this study was 46 families who have a child with developmental disabilities(mental retardation and/or autism) from three special educational programs in Seoul, Korea, Results from correlation and hierachial regression analysis revealed that perceived social support operated as a resiliency factor between family stress and coping. Child and family characteristics appeared to be important predictors of perceived social support and coping. In summary, there is evidence that the resource of social support as a family strength and capability was found to improve the family coping. These findings also must be viewed within the context that sample of families of children with disabilities was relatively small and eligible families from support group of special educational program.

The purpose of this study was to test Interaction Model of Client Health Behavior(IMCHB) of Cox repeatedly and to determine the contributions of sociodemographic variables, health experiences, family functioning, intrinsic motivation, health perception, self esteem, to health behavior of highschool students. A convenient sample of 2nd grade highschool students(N=638) responded to self-report questionnaires. The IMCHB was then tested with data using SAS program by frequency, t-test, ANOVA, regression. The results were as follows 1. Health behaviors were found to be gender specific. 2. From the body's model, mother and students health affected health perception and self-esteem among a set of background variables. Health perception and self-esteem are related to health behaviors. 20% of the varience in body's health behavior are explained by health perception and self-esteem. 3. From the girls model, students health explained 13.3% of health perception varience and father's health explained 11.6% of self-esteem varience. 16% of health behavior varience are explained by health perception and self-esteem. The results indicated that there was a relatively poor fit of the IMCHB to the highschool students data. But further study using the IMCHB to define health outcome in student is needed to verify the linkage. The model generated in this study clarified the contribution of some factors such as parental and student's health status. The results also indicated that the schoolnurse has to develop the health care program for students and their parent with community resources to improve health perception and self-esteem of students for intervening health behavior of highschool students.

The purpose of this study was to explore and describe the lived experience of the family caregivers with the demented elderly. For investigate purposes of this study, data collection was done from May 9th to October 16th 1997, by means of in-depth interviews with 6 individuals in caregiving families. The research question was "What are the lived experiences of being a family caregiver with the demented elderly? "All interviews were tape-recorded and transcribed for the analysis using Colaizzi's method. The main results of this study were as follows : 1) Family caregivers ascribed the cause of the dementia to 'environmental change' and the 'introverted personality of the elderly'. 2) Family caregivers let the demented elderly alone initially and then they restrained the elderly who was in a fit of dementia. 3) The coping response of family caregivers varied. The coping reponses were (1) having their moods go up and down, (2) enduring and praying, (3) avoiding the elderly, (4) hoping for release from responsibility, (5) enduring their conditions(obligations), (6) accepting the elderly, (7) taking an objective view, and (8) taking safety measures. 4) The long ordeal of coping with a demented elderly person resulted in the (1) loss of physical and psychological well-being, (2) ethical conflicts, (3) family conflicts, (4) become desperate, (5) rejection of the aging process, (6) sympathy and understanding for the elderly, (7) awareness that the support system is important and (8) hope of sharing their responsibility. The results of this study may help nurses to understand the lived experiences of the family caregivers with the demented elderly better, in order to provide more basic data for the development of educational programs for dementia family caregivers. It may help to make the coping process easier and more successful for the family members of the demented elderly.
