Purpose: The purpose of this study was to investigate RN-BSN students' clinical nursing competency in order to establish baseline data for developing nursing competency based clinical education for RN-BSN students. Method: A survey of 1,453 RN-BSN students from 21 nursing schools was conducted using a self administered questionnaire. Result: The mean score of the clinical nursing competency was 2.93. The scores for competency were shown as 2.91 for nursing management, 2.94 for developing professionalism & legal implementation, 2.95 for critical thinking, 2.96 for teaching & leadership, and data collection, basic nursing care, and communication were above 3.00. The items perceived as insufficient competency were physical examination and observation & monitoring in data collection, cardiopulmonary resuscitation, psycho-social care, spiritual care, hospice in basic nursing care, application of knowledge and theory, formulating nursing diagnosis, nursing care planning in critical thinking, education material development, leadership, delegation in teaching and leadership, analysis of organization, planning, infection control, role & job description, evaluation of nursing activities in nursing management, quality improvement, and research in developing professionalism and legal implementation. Conclusion: This study will contribute to developing a nursing competency based on clinical education for RN-BSN students who have various education needs and clinical backgrounds.

The Medical Research Council has for some years encouraged collaborative clinical trials in leukaemia and other cancers, reporting the results in the medical literature. One unreported result which deserves such publication is the development of the expertise to design and analyse such trials. This report was prepared by a group of British and American statisticians, but it is intended for people without any statistical expertise. Part!, which appears in this issue, discusses the design of such trials; Part II, which will appear separately in the January 1977 issue of the Journal, gives full instructions for the statistical analysis of such trials by means of life tables and the logrank test, including a worked example, and discusses the interpretation of trial results, including brief reports of particular trials. Both parts of this report are relevant to all clinical trials which study time to death, and would be equally relevant to clinical trials which study time to other particular classes of untoward event: first stroke, perhaps, or first relapse, metastasis, disease recurrence, thrombosis, transplant rejection, or death from a particular cause. Part I, in this issue, collects together ideas that have mostly already appeared in the medical literature, but Part II, next month, is the first simple account yet published for non-statistical physicians of how to analyse efficiently data from clinical trials of survival duration. Such trials include the majority of all clinical trials of cancer therapy; in cancer trials, however, it may be preferable to use these statistical methods to study time to local recurrence of tumour, or to study time to detectable metastatic spread, in addition to studying total survival. Solid tumours can be staged at diagnosis; if this, or any other available information in some other disease is an important determinant of outcome, it can be used to make the overall logrank test for the whole heterogeneous trial population more sensitive, and more intuitively satisfactory, for it will then only be necessary to compare like with like, and not, by chance, Stage I with Stage III.

The authors believe that farm livestok will be greatly affected by the marked increasing use of organic phosphate. This study was carried out to observe the clinical signs and histopathological changes of mouse, guinea pig, hamster and rabbit that were orally administered with diazinon used usually as agricultural insecticide, and cholinesterase (ChE) activity was histochemically examined in the liver, heart, kidney, adrenal gland, duodenum and salivary gland of these experimental animals administered with diazinon. The results obtained were as follows: 1. Clinical signs such as dullness, severe salivation, ataxia, dyspnea, irregular slight convulsion and inappetance and as the histopathological changes cloudy swelling, congestion and hemorrhage of parenchymal organs, catarrh or local necrsois of the gastrointestinal tract, congestion or hemorrhage of the other organs were observed. Especially, hemorrhage of adrenal glands (rabbit, guinea pig) and pulmonary congestion and hemorrhage were necessarily constant. 2. In the histochemical study, ChE activity appeared intensely in the liver, heart, medulla of adrenal glands and salivary glands (submaxillary and parotid) of control animals, but ChE activity was negative or markedly decreased in experimental animals administered with diazinon. There was no marked difference between the control and experimental animals in ChE activity of the kidney. 3. Histochemical observation of ChE activity was helpful to explain the clinical signs and histopathological changes and was regarded as a diagnostic method for organic phosphate poisoning.

This study was conducted to obtain information of the oral dose toxicity of low molecular fucoidan (LMF) in male and female mice. In order to calculate 50% lethal dose ($LD_{50}$) and approximate lethal dose (LD), test material was once orally administered to male and female ICR mice at dose levels of 2000, 1000, 500, 250, 125 and 0 (vehicle control) mg/kg (body wt.). The mortality and the changes on body weight, clinical signs, gross observation and organ weight and histopathology of principle organs were monitored 14 days after LMF treatment. We could not find any mortalities, clinical signs, body weight changes and gross findings. In addition, significant changes in the organ weight and histopathology of principal organs were not observed except for some sporadic findings. The results obtained in this study suggest that LMF may not be toxic in mice and may be therefore safe for clinical use. The $LD_{50}$ and approximate LD in mice after single oral dose of LMF were considered over 2000 mg/kg in both female and male mice.

The object of this study was to evaluate the single oral dose toxicity of Low Molecular Weight Fucoidan (LMF) in male and female rats. LMF was administered to female and male SD rats as an oral dose of 2,000, 1,000 and 500 mg/kg (body wt.). Animals were monitored for the mortality and changes in body weight, clinical signs and gross observation organ weight and histopathology of 14 principle organs were examined upon necropsy. As the results, no LMF treatment related mortalities, clinical signs, changes on the body and organ weights, gross and histopathological observations against 14 principle organs were detected up to 2,000 mg/kg in both female and male rats except for some sporadic findings not LMF treatment related toxicological signs. Therefore, $LD_{50}$ (50% lethal dose) and approximate LD of LMF after single oral treatment in female and male rats were considered over 2,000 mg/kg - the limited dosages recommended by KFDA Guidelines [2005-60, 2005], respectively.

In clinical clerkships, residents function as trainees, workers, and teachers for other medical students. Although residents care for patients in harsh environments and encounter precarious patient-safety situations, they are working towards becoming competent specialists. Residency education programs are very important in cultivating specialists able to adapt to the rapidly-changing medical environment, and are also necessary to improve the quality of specialist training. Competent specialists not only need clinical competency, but also a wide range of abilities including professionalism, leadership, effective communication, cooperation, and attention to continuous professional development/continuing medical education activities. Each Korean association of specialties has its own educational goals and standardized education programs to help residents learn specific techniques and competencies related to medical care for patients, though the training environment of each residency is different within each trainee hospital. Although it is also important to evaluate residency education programs, currently there is only an examination of knowledge and assessment of skills based on mini-clinical evaluation exercises or direct observation of procedural skills. In order to develop an objective and estimable evaluation tool that can assess the overall achievement level within each training course, it is necessary to evaluate the knowledge, skills, and attitudes of residents. Residency education programs need further attention and reform.

Objectives: The prostatitis is characterized as relatively uncurable chronic recurrent illness. Because it is so difficult to treat, this study was designed to evaluate the clinical effects of herb medicine, acupuncture, and herbal acupuncture therapy on chronic prostatitis. Methods: A clinical observation was made on thirty patients with chronic prostatitis. They were treated with herb medicine, acupuncture, and herbal acupuncture therapy. Before and after treatment we measured NIH-CPSI(National Institutes of Health Chronic Prostatitis Symptom Index). Results: After treatment NIH-CPSI was decreased considerably. Conclusions: This suggests a role for oriental medical therapy in treating prostatic diseases. Further study into approach and application of these treatments for prostatitis is needed.

The present study was conducted to investigate the acute toxicity of plant sterol ester by a single oral dose in Sprague-Dawley rats. Ten males and 10 females aged 5 weeks were randomly assigned to two groups of 5 rats each and were administered by gavage at dose level of 0 or 20 ml/kg body weight. Parameters measured during the 14-day observation period were mortality, clinical signs, body weight changes, and gross findings. No mortality was observed in the present study. Treatment-related clinical signs, such as pasty stool and diarrhea, were observed on the day of treatment and these signs resulted in soiled fur on day 1 after the treatment. However, no clinical signs were observed on days 2-14 after the treatment. There was no significant difference in body weight changes between the control and treatment groups. At necropsy on day 14 after the treatment, no treatment-related gross findings were observed in the treatment group. Based on these results, it was concluded that a single oral dose of plant sterol ester induced pasty stool and diarrhea in Sprague-Dawley rats at dose level of 20 ml/kg and that the lethal doses were considered to be over 20 ml/kg for both sexes.

Objective : In 1983 Autosomal dominent spinocerebellar ataxia(ADCA) has been classified to four types by a useful clinical features according to Harding. Since 1993 ADCA referred to as SCA by molecular genetic characteristics. We focused on the improvement of clinical symptoms in SCA patient through oriental medical treatment. Methods ＆ Results : The assessment included neurophysiological examination and clinical symptoms. For example slow saccade, gaze limitation, upward and lateral, nystagmus, truncal and gait ataxia. The patient(M/30) was clinically charaterized by ocular abnormalities, trunkal and gait ataxia and the MRI showed atrophy of cerebellar vermis. The patient was taken both common acupuncture and Dong-Si venepuncture on Hwasan with herbal medicine. Before the treatment Rt. ocular movement were slowed and a significant eye fixation was observed always in abduction and intermittently presented trunkal and gait ataxia. During the treatment trunkal and gait ataxia has not been presented and ocular obnomalities changed to normal state. This case suggests the possibility of oriental medical treatment on SCA but further observation is needed on this patient.
