Dysfunction of the inferior alveolar nerve may result from trauma, diseases or iatrogenic injury. The development and refinement of an objective method to evaluate this clinical problem is highly desirable and needed, especially concerning for an increasing medico-legal issue. Evoked potential techniques have attracted considerable attention as a means of assessing the function and integrity of nerve pathways. The purpose of this study was to characterize the Sensory Evoked Potentials(SEPs) and Somatosensory Evoked Potentials(SSEPs) elicited by electrical stimulation of mental nerve. SEPs and SSEPs were measured and analyzed statistically before and after needle injury on the inferior alveolar nerve of Sprague-Dawalye rats. Measuring SEPs was more sensitive in evaluation of the recovery of sensory function from inferior alveolar nerve injury then measuring SSEPs but we measured SSEPs in the hope of providing a safe, simple and objective test to check oral and facial sensibility, which is acceptable to the patient. We stimulated mental nerve after needle injury on the inferior alveolar nerve and SEPS on the level of mandibular foramen and SSEPs on the level of cerebral cortex were recorded. Threshold, amplitude, and latency of both of SEPs and SSEPs were analyzed. The results were as follows ; 1. Threshold of SEPs and SSEPs were $184{\pm}14{\mu}A$ and $164{\pm}14{\mu}A$ respectively. 2 SEPs were composed of 2 waves, i.e., N1 N2 in which N1 was conducted by II fibers and N2 was conducted by III fibers. 3. SSEPS were composed of 5 waves, of which N1 and N2 shower statistically significant changes(p<0.01, unpaired t-test). 4. SEPs and SSEPs were observed to be abolished immediately after local anesthesia and recovered 30 minutes later. 5. SEPs were abolished immediately after injury. N1 of SSEPs was abolished immediately and amplitued of N2 was decreased($20.7{\pm}12.2%$) immediately after 23G needle injury, but N3, N4 and N5 did not change significantly. Recovery of waveform delayed 30 minutes in SEPs and 45 minutes in SSEPs. 6. The degree of decrease in amplitude of SEPs and SSEPs, after 30G needle injury was smaller than those with 23G. SEPs recorded on the level of mandibular foramen were though to be reliable and useful in the assessment of the function of the inferior alveolar nerve after injury. Amplitude of SSEPs reflected the function and integrity of nerve and measuring them provided a safe, simple and abjective test to check oral and facial sensibility. These results suggest that measuring SEPs and SSEPs are meaningful methods for objective assessment in the diagnosis of nerve injury. N1 and N2 of SSEPs can be useful parameters for the evaluation of the nerve function following a needle injury.

The purpose of this study is to affect health improvement of adolescent, to understand behavioral causes follow adolescent's drug abuse, to understand recovery and rehabilitaton process of adolescent drug abuser. The data are collected through open questionnaire and interview of 25 adolescents from the experienced drug abuse 16 students(male 8, female 8) in two vocational high schools and admissing adolescents 9 person in Alcohol-Drug Addiction Care Centre in Seoul from June 28th to August 31st, 1994. The collected data are arranged and explained through categorizing method stated contents about motives, causes, experiences and effected behaviors for using the drugs of drug abuser adolescents. DRUG USING MOTIVATION They are almost first son and daughter in their family. In their conversation person, male converses to their mother well, but female does not converse to their parents include family. Both groups respond positively to companionship and attitude to other, but negatively to self-confidence and actualizing attitude. They hope always peace of family and want to do their best for their life. In school group, hard and difficult things are school life and family problems, also using the drugs for resolving the them. About drug using behaviors, male responds to bad habbit and shamfull, but female is unconcerned with drug using attitude. The first background of drug using, male gets to use because of curiosity and to be induced from friends or seniors, but female gets to use for feminine beauty(thin body) and escape from reality. Used the drugs, male uses frequently Bond, Butane-Gas among inhalation materials and also marijuana, but female uses various diuretics. The times of drug using, both groups repond to use during the chaging of emotion or filling with stress. The place of drug using, both groups take drugs in vacant houses or in the mountain. The frequency of drug using, they use almost once in a day and they use mostly alone or drug user in friends. Experienced mental changing after drug using, which is fantasy, ecstasy, anxiety and suicidal feeling, and experienced physical changing after drug using, which is elevating sense, headach, abdominal pain, dyspnea and chaging of skin colour and reddish. They coincide with inconvenience feeling due to drug using. RECOVERY AND REHABILITATION PROCESS OF DRUG USING ADOLESCENTS The reason for reforming drug using behavior and attitude, both groups respond to reforming for oneself and social life. The difficult things during the stop to using drugs, all of them responed to family problems, friends problems and temptation and impulse. As for stop to using drug, they need good advise, understandable attitude and family love. But they do not need to be stigmatized, scolding, over protect and ridicule of friends. Also they entreat continuous understanding, advise, concern and the method for resolving stress. For the friends to want to use the drug, they will talk about the stories of their personal experiences and for the friends to stop to using the drug, they will consider for them how to stop. From the theses results, drug users understand personal problems due to drug using, and consider about why to stop and how to stop. Also drug users need to resolve the family problems, personal problems, stress and temptations or impulses. Accordingly this paper suggests that drug users in adolescents need understandable and acceptable atitudes, loving and tenderness, continuous advice and concern, and hopes for life.

Nursing involves deep human interpersonal relationships between nurses and patients. But in modem Korea, the nurse - patient relationship tends to be ritualistic and mechanestic. Patients usually express the hope that nurses be more tender and kind. Patients expect nurses to express their warmth especially through nonverbal behaviour. This study was conducted to identify patients' preferences for nurse's nonverbal expressions of warmth. Through the confirmation of these preferences, nurses may learn how to enhance their interpersonal relationships with patients. Subjects for the study were 73 patients who had been admitted to a university teaching hospital for at least three days and agreed to be interviewed by the investigator. The interactions were studied nonverbal expressions of warmth during nursing rounds and administration of oral medication. The interview schedule was expecially designed by the investigator to measure the nurse's posture, the distance between the nurse and the patient, the nurse's eye contact, facial expression, hand motion and head nodding. Data analysis included frequencies, percentages and X²-test. The results of this study may be summerized as follows : 1. Patient's preferences for nurse's nonverbal expressions of warmth during nursing rounds. Preferred nurse's posture was sitting(50.7%) or standing(49.3%) opposite the patient. Preferred distance between the nurse and the patient was close to the bed(93.2%), less than 1m. Preferred eye contact was directed to the patient's eyes or their affected part (41.1%). Preferred facial expression was a smile(97.3%). Preferred hand motions were light gestures(41.1%). Patients preferred head nodding which approved their own opinions(69.9%). 2. Patient's preferences for nurse's nonverval expressions of warmth during administration of oral medication. Preferred nurse's posture was standing and waiting to confirm that the medication had been taken(58.9%). Preferred distance from the patient was at arm's length, 0.5-1m(64.4%). Patients preferred direct eye contact(58.9%) and a smile(94.5%). Patients preferred that the nurse put the medicine directly the patient's hand(64.4%). Whether the nurse nodded her head or not was not considered important. 3. The relation of general characteristics and patient's preferences for nurse's nonverbal expressions of warmth during nursing rounds and administration of oral medication. During nursing rounds, the age of subjects(p＝0.010) and the standard of education(p＝0.026) related to the distance between the nurse and the patient. The sick hospital ward related to the eye contact(p＝0.017) and facial expression(p＝0.010). During administration of oral medication, the age of subjects(p＝0.044) and days of hospital treatment (p＝0.043) and the sick hospital ward(p＝0.0004) related to the facial expression. From this study, nurses can learn what kind nonverbal expressions of warmth are preferred by patients during rounds and administration and thus will enhance nurse- patient interpersonal relationships.

연구목적：자살사고에 관한 1차 선별검사 도구를 개발하고자 현재 세계적으로 널리 사용되고 있는 Reynolds의 자가보고형 청소년 자살사고 설문(SIQ-JR)을 번안하여 우리나라 청소년에 적용하여 한국판 SIQ-JR 척도에 대한 신뢰도 및 타당도를 검증하고자 하였다. 방 법：서울시내 남녀 중고등학생 총 1,160명과, 정신과에 내원한 청소년 임상환자 114명을 연구대상으로 하였다. 연구도구로는 SIQ-JR 이외에, 자살관련 8가지 국내 표준화된 척도(분노, 우울, 불안, 절망감, 공격성, 충동성, 내외통제, 자아평가)를 시행하였다. 결 과：전체 SIQ-JR 총점 평균은 여자가 남자 보다 높았고, 고등학생이 중학생 보다 높았지만 모두 통계적으로 유의미하지 않았다. 임상군의 경우 일반 학생군과 높은 변별력(p<0.01)을 보였다. SIQ-JR의 내적일관성을 나타내주는 신뢰도계수는 0.92-0.94, 검사-재검사 상관계수는 0.68-0.78, 항목-전체 상관계수는 0.59-0.82로 모두 높은신뢰도를 보였다. 요인분석 결과 타인에 대한 고려가 독립된 요인으로 추출되었는데 이는 서구의 개인주의와 다른 우리나라의 문화적 배경을 반영한다고 여겨졌다. 공존 타당도 분석결과 자살사고와 자아평가척도와 분노조절척도 점수와는 역상관관계였으며 나머지 6개 척도와는 정상관관계였다. 전체대상의 자살사고 점수와 가장 연관이 높은 척도는 우울척도(r=0.42), 공격성 척도(r=0.36), 특성불안척도(r=0.35), 분노척도의 하위척도인 내재화된 분노(r=0.31) 순이었다. 남자와 고등학생의 경우 공격성(r=0.37)이 가장 자살사고와 관련이 높은 척도였다. 그러나 절망감척도와 충동성척도는 자살사고와 낮은 상관관계를 보였다. 결 론：이상을 살펴볼 때 한국판 자살사고 척도는 만족할만한 신뢰도와 타당도를 얻었다고 여겨지는바 학교, 지역사회, 임상현장에서 1차적 자살사고 선별검사 도구로서의 활용이 기대된다.

This study has been done in order to help the people understand the cancer patients and provide the basic materials for the care of cancer patients by deeply understanding the living experience of the practice of alternative therapy for cancer patients. Data were collected with several in depth interviews and observations. Collected datas were analyzed by using phenomenological method of study by Giorgi (1970). The trial experience of alternative therapy for cancer patients has been classified into the one of having concerns, following, being infatuated, and coming out by pushing, and the experience of having concerns appeared as the meaning of the limit of modern medicine, despair, loneliness. hope, emotional support. dissolution of the feeling of uneasiness. the feeling of burden of the medical expense, self-treating, the subject of treatment. and indifference while the experience of following appeared as the meaning of blind following, temptation, going outside to look for something, wandering. following unconditionally, advise of the professionals, mistaken belief. self-abandonment, powerlessness. disconnection of dialogue with the medical staff. elevation of immunity, strengthening the physical power, absence of the source of examined information, clinging, self-responsibility. the experience of being infatuated appeared as the meaning of thorough trial. affirmative experience. devotion. diverse efforts, faithful trial. affirmative self-suggestion. change of the style of life. the feeling of burden of expense, being envious, bitter feeling toward the family, considering family, family discords, and difficulty of enforcement. The experience of coming out by pushing appeared as the meaning of waiting. self-reflection. maintaining the distance. cutting attachment, throwing the greed away, coming out by pushing. being thoughtful. accepting disease. individual difference of physical quality, and ambivalence. But they return to the experience of being concerned all over again in case of recurrence or metastasis of the disease even though they come out of such stage, and they always have ambivalence even in the condition with no recurrence and metastasis. In conclusion, the trial of alternative therapy for cancer patients could be explained as the adaptive behavior to the disease which is difficult to be cured. the cancer. The cancer patients are exposed to the side effects and harm without the examined information resources. Therefore the nurse should well aware of the alternative therapy and be able to do the appropriative management through the open communication with the patients who are under the trial of alternative therapy.

This study is to survey the materials purchasing and inventory management status and the characteristics and opinions of the staff in charge of purchasing and inventory of the general hospitals in Busan area in order to contribute to the rationalization of its management through the grasp of actual situation and the presentation of desirable improvement plan for the materials purchasing and inventory management. The status of medical institute had been surveyed by the purchasing/ administration managers of total 26 general hospitals, and the purchasing/ management questionnaires had been commenced with 86 staff of the 26 hospitals. Its major survey results, after the analysis of 24 medical institute statuses (return rate of 92.30%) and 60 staff questionnaires (return rate of 69.76%), are as follows. First, post-purchasing evaluation system is not used actively, orders are being placed by phone or fax, and general merchandise is being purchased through free contracts in most of the hospitals participated in the survey. Second, as per the materials supplying methods, the requisition and delivery system is currently the most popular in the hospitals surveyed, however, both the requisition and delivery system and the par level transfer system are the most desired in the hospitals of more than 500 beds, and the par level transfer system is the most desired in the hospitals under 500 beds for the materials supplying system in the future. Third, as per the inventory management system that is desired the most in the future, the SPD and JIT types are preferred in the hospitals of more than 500 beds, the stockless strategy is preferred in the hospitals under 500 beds, the senior staff above section chief grade prefer the stockless strategy, and the junior staff prefer the ABC classification and SPD types. Fourth, The necessity of purchasing staff's training for the materials management is highly recognized but the effectiveness is not so much acknowledged, which is because such a training is thought to be so superficial and formal that it is not helpful much in the actual field. When summarizing the survey results as above, the materials purchasing and management system is differed for each group of hospitals according to the size of beds, and the more scientific management system is largely required by the general hospitals in Busan city. They also hope the introduction of joint purchasing system, materials management by the bar-code system, and positive execution of the market survey and training of the relevant staff for the management of purchasing affairs. So the more systematic purchasing and inventory management is regarded to be necessary through the introduction of scientific and specialized education of materials management, market survey, and post-purchasing evaluation system also through the computerization of materials purchasing and inventory management as soon as possible.
