Objectives: This study was performed to evaluate the laboratory system for successful PGD using fluorescence in situ hybridization (FISH) and the clinical outcome of PGD cycles in five years experiences. Methods: A total of 181 PGD-FISH cycles of 106 couples were performed, and diagnosed chromosome normality in the preimplantation embryos. The laboratory and clinical data were classified by the following optimization steps, and statistically analyzed. Phase I: Blastomere biopsy with two kinds of pipettes, removal of cytoplasmic proteins without treatment of pepsin and culture of biopsied embryos with single medium; Phase II: Blatomere biopsy with single pipette, removal of cytoplasmic proteins with pepsin and culture of biopsied embryos with single medium; Phase III: Blastomere biopsy with single pipette, removal of cytoplasmic proteins with pepsin and culture of biopsied embryos with sequential media. Results: A total of 3, 209 oocytes were collected, and 83.8% (2, 212/2, 640) of fertilization rate was obtained by ICSI procedure. The successful blastomere biopsies were accomplished in 98.6% (2, 043/2, 071) of embryos, and the successful diagnosis rate of FISH was 94.7% (1, 935/ 2, 043) of blastomeres from overall data. Embryo transfers with normal embryos were conducted in 93.9% (170/181) of started cycles. There was no difference in the successful rate of biopsy and diagnosis among Phase I, II and III. However, the pregnancy rate per embryo transfer of Phase III (38.8%, 26/67) was significantly (p<0.05) higher than those of Phase I (13.9%, 5/36) and Phase II (14.9%, 10/67). Conclusions: The laboratory optimization and experience for the PGD with FISH procedure can increase the pregnancy rate to 38.8% in the human IVF-ET program. Our facility of PGD with FISH provides the great possibility to get a normal pregnancy for the concerned couples by chromosomal aberrations.

This survey study was aimed at identifying the degree of educational need of the KNOU(Korea National Open University) nursing students defined as admission purposes, satisfaction of distance learning education, learning methods, and courses after graduation. Among randomly assigned 1000 students, 320 KNOU nursing students who allowed to participate in the study completed the questionnaires. The data were analyzed using descriptive statistics, chi-square test, and t-test, Results of this study were as follows : 1. The admission purposes of the KNOU nursing students were 'in order to get a bachelor's degree(83.8%)', 'to acquire knowledge for task(61.3%)', or 'to be admitted for the graduate school (53.1%)' etc. Comparing the admission purposes by age, tow items- 'to explore new possibilities for myself' and 'excellent curriculum' showed statistically significant differences. These two items were also found to show significant differences by marital status. 2. For the media maintenance, the results showed that students use their own cassett radios(96.3%), VTR(49.4%), TV only for the study (44.1%), personal computer (3.31%), or joining Hitel (6.3%). 3. Listening rates of the radio lecture were 'over 80%(9.1%)', '50-80%(9.1%)', '20-50%(18.1%)', 'below 20%(30%)' and 'never(33.1%)', And record lecture showed listening rates as follows : 'over80%(17.2%)', '50-80%(15.9%)', '20-50%(24.4%)', 'below 20%(27,2%)' and 'never(14.4%)'. 4. The difficulties with KNOU life were 'listening radio lectures(38.8%)', studying by following teaching schedules (37.8%)', 'isolated self-study(10.3%)', and 'appearance in the attending classes(8.1%)'. 5. As for satisfaction with teaching methods, the data showed that 81.2% of the respondents were satisfied (or very satisfied) with 'attending classes' and 75%, with 'paper lectures'. On the other hand some of respondents were very dissatisfied with 'recorded lecture(12.8%)' and 'radio lecture(10.9%)' 6. The results also showed that the students want to have 'video conferencing lecture(77.2%)', 'cable TV(64.1%)' and 'CD ROM program' to improve learning effects. 7. Concerning learning attitudes, 48.8% of the students reported 'study mainly for examnination', and only 4.1% answered 'study every day with plan'. The learning attitude showed significant differences by marital status and age. The students also evaluated themelves as 'study very hard(5.9%)', 'study hard in general(41.6%)', 'study a little(40.3%)' and 'study little(11.9%)'. 8. The students responded the most effective learning material was the 'textbook (92.2%)'. 9. For the purposes of using the local center, the results showed 'for the attending classes(76.3%)', 'for the use of references(14.7%)', and 'for the study group(66.7%)'. 10. The results revealed that 20.3% of the respondents had ever experienced unregistration or temporary withdrawal, and 53.4% among them did not register more than one time. The most common reason for the unregistration was 'due to family affairs or their job (70.8%)'. 11. 88.1% of the respondents answered 'they will graduate without fail'. 12. Regarding the benefits from the KNOU graduation, respondents indicated 'graduate school admission(38.1%)', 'self-confidence in social life(17.5%)', and understanding social problems (10.9%)'. 13. 64.4% of the students showed that they have intention to enter the graduate school. The item 'changing work place' showed statistically significant differences by marital status and age.

The purpose of this study was to serve as a basis for the planning of oral health education and the development of an oral health-promotion program for patients who visited dental clinics by examining how much dental hygienists offered oral health education to adult patients at dental clinics. A parent group was selected, being made up of 1,600 dental hygienists who registered with the Dental Hygienist Association and worked in Seoul. The questionnaire survey was carried out and an ${\chi}^2-test$ was made using the data collected from 218 subjects to determine how their practice of oral health education was different according to certain general characteristics(the sort of organization for which they worked, age, the term of their service, and the mean number of patients per day). As a result, the following findings were obtained: 1. Thees general characteristics made the following differences to the content of oral health, education: The sort of organization for which the subjects worked made a significant difference in the following tooth brushing instruction (p<0.05), the effect of oral prophylaxis or education about aftereffects (p<0.05), the regular examination of prosthesis (p<0.05), smoking-prohibition education (p<0.05), and the prevention poor-quality fillings (p<0.01). The mean number of patients per day made significant differences to the regular examination of prosthesis (p<0.05) and the prevention poor-quality fillings (p<0.01). But no significant disparity was generated by age or the term of service. 2. The general characteristics made the following differences to education about nutrition and diet counseling: The sort of organization for which the subjects worked had a significant effect just on the importance of a balanced menu (p<0.05). Age made significant differences in advice for vitamin, mineral, protein or other nutrients (p<0.01), and the importance of balanced menu (p<0.001). The term of service made significant differences in the importance of balanced menu (p<0.01), and advice for nutrients including vitamin, mineral or protein (p<0.01). 3. The general characteristics made the following differences to the recommendation and use of oral hygiene aids: The sort of oragnization for which they worked made significant differences only to a gingival massager and water pick (p<0.05). No significant difference was produced by age, the term of service or the mean number of patients per day. 4. The use of educational media for oral health was different according to the general characteristics: The use of pamphlets or booklets significantly varied depending on the organization for which they worked and with the mean number of patients per day (p<0.05). The use of slides or slide projectors was significantly affected by age (p<0.05). But no significant disparity was yielded by the term of service. 5. The general characteristics made the following difference as to whether a continued oral management system was carried out or not: The sort of organization for which they worked had very a significant effect on this result (p<0.001), and no significant disparity was made by age, the term of service or the mean number of patients per day. 6. The place where oral health education was giver differed according to the following general characteristics: The sort of organization for which they worked made very a significant difference as to the use of an examination room's dental unit chair or waiting room (p<0.01), and to the use of an oral health education room or reception counter (p<0.001). The term of service had a significant effect on the use of a counseling room (p<0.01). And the mean number of patients per day made significant differences in the use of a dental unit chair or reception counter (p<0.05), and to the use of an oral health education room or waiting room (p<0.01).

In this study, we attempted to investigate the needs and problems of the terminal cancer patients and their family caregivers to provide them with nursing information to improve their quality of life and prepare for a peaceful death. Data was collected from August 1, 1995 to July 31, 1996 at the internal medicine unit of S hospital in Seoul area with the two groups of participants who were family members of terminal cancer patients seventy four of them were in-patients and 34 were out-patients who were discharged from the same hospital for home care. The research tool used in this study has been developed by selecting the questionnaires from various references, modifying them for our purpose and refining them based on the results of preliminary study. While general background information about the patients was obtained by reviewing their medical records, all other information was collected by interviewing the primary family caregivers of the patients using the questionnaire. The data collected were analyzed with the SPSS PC/sup +/ program. The results of this study are summarized as follows ; 1) Most frequently complained symptoms of the terminal cancer patients were in the order of pain(87%), weakness(86.1%), anorexia(83.3%) and fatigue (80.6%). 2) Main therapies for the terminal cancer patients were pain control (58.3%), hyperalimentation(47.2%) and antibiotics(21.3%). 3) Special medical devices that terminal cancer patients used most were oxygen device (11.1%), and feeding tube(5.6%). Other devices were used by less than 5% of the patients. 4) The mobility of 70.4% of the patients was worse than ECOG 3 level, they had to stay in bed more than 50% of a day. 5) Patients wanted their medical staffs to help relieve pain(45.4%), various physical symptoms(29.6%), and problems associated with their emotion(11.1%). 6) 16.7% of the family caregivers hoped for full recovery of the patients, refusing to admit the status of the patients. Also, 37% wished for the extension of the patient's life at least for 6 months. 7) Only 38.9% of the family members was preparing for the patient's funeral. 8) 45.4% of family caregivers prefer hospital as the place for the patient's death, 39.8% their own home, and 14.8% undetermined. 9) Caregivers of the patients were mostly close family members, i.e., spouse(62%), and sons and daughters or daughter-in-laws(21.3%). 10) 43.5% of the family caregivers were aware of hospice care. 46.8% of them learned about the hospice care from the mass media, 27.7% from health professionals, and the rest from books and other sources. 11) Caregivers were asked about the most difficult problems they encounter in home care, 41 of them pointed out the lack of health professionals they can contact, counsel and get help from in case of emergency, 17 identified the difficulty of finding appropriate transportation to hospital, and 13 stated the difficulty of admission in hospital as needed. 12) 93.6% of family caregivers demanded 24-hour hot line, 80% the visiting nurses and doctors, and 69.4% the volunteer's help. The above results indicate that terminal patients and their family caregivers demand help from qualified health professionals whenever necessary. Hospice care system led by well-trained medical and nursing staffs is one of the viable answers for such demands.

The purpose of this study was to identify the care needs of family-caregivers to the patients with stroke. Subjects were 115 family-caregivers caring for the patients while they were in-patients or out-patients with stroke in two general hospitals and one oriental medicine hospital located in Seoul and Kwang-Ju. The instrument used for this study was made by the researcher on the basis of results of literature review and interviews with family-caregivers, composed of 35 items. Internal validity by calculation of cronbach's alpha with data of respondents was 0.91, which was regarded as high. The Data were analyzed by SAS program, with percentage, mean, t-test, and ANOVA. Factor structures of care needs of family-caregivers were elicited by factor analysis(PCA, Varimax rotation). Datum collection had been from July 1 to August 14, 1997. The results of this study were as follows : 1. The mean score of the sum of the care needs of family-caregivers was 3.96 and the highest-mean item was 'need for immediate care(M=4.77)', and the lowest-mean item was 'need for chaplian's visit (M=2.82)'. 2. Care needs of the family-caregivers were : Need to be informed of the disease, treatment and care ; need of education and assistance related to physical functional level ; need of social support and consultation ; need of management of nursing problem related to immobility ; need of appreciation ; need of the way to communicate with patients ; need of immediate care and help. The highest mean factor was the 'need for immediate care and help(M=4.74)', and the lowest mean factor was the 'need of appreciation(M=3.58)'. 3. The variables influencing the degree of care needs perceived by family-caregivers to the patients with stroke were as follows : There were significant differences between need to be informed of the disease, treatment and care and general characteristic factors, which were family caregiver's sex (p=.0178), caring period(p=.0223) and patient's suffering period(p=.0244). There were significant differences between need of education and assistance related to physical functional level and general characteristic factors, which were patient's paralysis(p=.0177), patient's ADL dependency(p=.0032). There were significant differences between need of social support and consultation and general characteristic factors, which were family caregiver's sex(p=.0055), occupation(p=.0159), religion(p=.0093) and patient's sex(p=.0134). There was significant difference in the degree of need of management of nursing problem related to immobility, according to the patient's ADL dependency(p=.0493). There were significant differences between need of appreciation and general characteristic factors, which were family caregiver's age(p=.0107), sex(p=.0133), and patient's age(p=.0338). There were significant differences between need of the way to communicate with patient and general characteristic factors, which were patient's paralysis(p=.0002) and aphasia(p=.0001). There were significant differences between need of immediate care and help and general characteristic factors, which were family caregiver's caring period(p=.0162) and patient's suffering period(p=.0116). 4. The mean score of patient's ADL dependency was 3. 38 and the highest-mean item was 'ascending and descending stairs(M=4.12)', and the lowest-mean item was 'drinking(M=2.60)'. There was no significant difference in the degrees of care needs related to the patient's ADL dependency. 5. The highest information source of family-caregivers was from the doctors about the disease, treatment and care(26.1%). The second highest one was from mass media(20.8%), and the third one was from the nurses. The above findings may be used as the basic data to seek more efficient way of elevating nursing practice and quality for family-caregivers to the patients with stroke.

목적:본 연구에서는 새로 개발된 다이오드 레이저 제품을 이용하여 레이저 파워에 따른 온도변화와 박테리아 멸균 비교실험을 통하여 기존 제품과의 임플란트 주위염치료에 대한 효과를 비교 실험하였다. 연구 재료 및 방법: 808 nm Diode laser와 810 nm Diode laser를 사용하여 디스크에 레이저를 60초간 조사하였으며, 출력은 1 - 2.5 W로 설정하였다. 온도측정 모듈과 온도측정 프로그램을 이용하여 disc 표면온도변화를 측정하였다. 또한, SLA, RBM이 코팅된 disc에 bacteria 도포 후, 808 nm Diode laser를 30초간 조사하였으며, 출력은 0.5 - 3 W로 설정하였다. 결과: 808 nm, 810 nm 두 장치 모두 출력이 증가함에 따라 온도 상승폭은 증가하였다. 모든 조건에서 810 nm laser를 조사하였을 때 초기온도상승속도, 하강속도 및 전후의 온도변화량은 808 nm laser 보다 높았다. 레이저 조사 후 티타늄 디스크 표면의 변화는 두 레이저 모두에서 관찰되지 않았다. Bacteria가 도포된 디스크에 808 nm laser를 조사한 결과, 출력이 증가 함에 따라 살균효과가 증가하는 것을 확인하였다. 결론: Diode laser를 임상에 적용하는 경우, 동일한 출력에서 온도의 변동폭이 적고 최대 상승온도가 낮은 808 nm laser가 환자에 안전할 것으로 사료된다. 하지만 실제로 임상에 적용하기 위해서는 보다 다양한 안전성평가를 실시하여 장비에 대한 신뢰성을 확보하여야 할 것이다.
