This paper examines the outcomes and tasks of U rail privatization especially focusing on the rail safety. Earlier research which focused on the rail safety had little knowledge of the explanations for recent changes of safety scheme. Moreover, they had difficulty making a direct comparison of safety between national rail and the privatized rail. Therefore we are left without a good explanation which has a comprehensive perspective. I attempt to show the outcomes of safety in the rail privatization process and its tasks focusing on the recent fatal accident. This paper argues that the UK's rail safety has a framework which is too complicated with overlapping responsibilities that brought about inefficiency, increasing costs. Especially infrastructure enterprise did not come to play an appropriate role. However, after 2000, the government took charge of setting the strategy for railway safety, and the Office of Rail Regulation covered safety, performance and cost. I explain that these changes present a good opportunity to solve the problem of passing the buck for rail accident. Through the analysis, I find that outcomes of rail privatization in safety are improved comparing the national rail. However, safety performance, for example the collision of structures of cars and looseness of rail should be improved. In future, the problems of fatal accident and a bit of duplicate safe system should be addressed.

Purpose: The purpose of this study was to develop clinical education of Oriental Nursing. Methods: The subjects were one hundred and ninety-three students who have completed clinical practice. The questionnaires were composed of experience type and Oriental Nursing practices(25 items), level of satisfaction(20 items), difficulty level of practices(6 items), and preparation level of practice instructor(5 items). The reliability were Chronbach's $\alpha$=.84, .86, .74, and .93 respectively. Frequencies, percentage, t-test, and Pearson's Correlation was used in data analysis using SPSS PC+ 11.0. Results: Nursing students recognized that they had difficulties caused by a lack of knowledge of Oriental medicine, of learning the uniqueness of the nurse's role and lack of nurse's enthusiasm in teaching students. However, they were confident in preparing acupuncture and implementing Moxibustion, large Moxibustion, Bu-Hang therapy, aroma therapy and on administration of medicines and control of temperature of the medicines, exercise and rehabilitation. Therefore, instructors should train nursing students by developing a unique Oriental Nursing practice and reinforcement of nurses' independent and cooperative roles through the acquisition of Oriental Medical knowledge and terminology. It is necessary that they develop an educational program based on Oriental Nursing practice, perform consistently within the program and train its teaching faculty and instructors.

Mitochondria play a crucial role in many essential biological events by way of the electron transport chains and intermembrane proteins that they contain. Abnormalities in the mitochondria are strongly correlated with the development of diseases such as atherosclerosis, cancer, and diabetes. However, the study of mitochondria has been referred to as 'labor-intensive' because of the difficulty in isolating the organelles from their various sources, which can include cultured cells and tissues. Multiple companies provide mitochondria isolation kits, and it is possible for investigators to use different kits and apply different protocols depending on the source of the mitochondria. Therefore, we focused on producing an isolation buffer that could be applied to both cultured cells and tissues, and optimized an isolation protocol that could be used with both. Specifically, we adjusted the buffer condition that can be applied to human cervical cancer cells, fibroblasts, and tissues such as mouse liver and spleen. We also optimized the protocol to improve the efficacy and efficiency of the steps involved in the isolation of mitochondria. These methodological improvements may contribute to advanced research by allowing investigators to overcome the difficulties involved in isolation of mitochondria from biological samples.

Purpose: This study was performed to analyze the visiting nurses' job using Developing a curriculum (DACUM). Methods: The DACUM committee with 6 visiting nurses participated in the workshop. In this workshop, the visiting nurses role was defined and their duties and tasks were identified. After content validation via the experts, the pilot test was conducted to 78 nurses. Results: A total of 13 duties and 82 tasks were identified on the DACUM chart which represented the importance, difficulty, and frequency of tasks with alphabet A, B, and C as its higher degree. Regarding duties, 'visiting nursing for high risk group' is the highest, while the lowest was 'public welfare events'. Regarding to tasks, 'discovering a new patient' was the highest, while 'selecting patients and offering medical supplies (nutritional supplement, patch)' was the lowest one. Conclusion: The results showed that visiting nurses working in the visiting health care service center were doing more various duties and tasks than those working according to 'Act on Long-term Care Insurance for the Aged'. The results can be used to develop training programs for visiting nurses and evaluation-scale of their job performance.

Sacral nerve stimulation (SNS) is an effective treatment for bladder and bowel dysfunction, and also has a role in the treatment of chronic pelvic pain. We report two cases of intractable pain associated with cauda equina syndrome (CES) that were treated successfully by SNS. The first patient suffered from intractable pelvic pain with urinary incontinence and fecal incontinence after surgery for a herniated lumbar disc. The second patient underwent surgery for treatment of a burst fracture and developed intractable pelvic area pain, right leg pain, excessive urinary frequency, urinary incontinence, voiding difficulty and constipation one year after surgery. A SNS trial was performed on both patients. Both patients' pain was significantly improved and urinary symptoms were much relieved. Neuromodulation of the sacral nerves is an effective treatment for idiopathic urinary frequency, urgency, and urge incontinence. Sacral neuromodulation has also been used to control various forms of pelvic pain. Although the mechanism of action of neuromodulation remains unexplained, numerous clinical success reports suggest that it is a therapy with efficacy and durability. From the results of our research, we believe that SNS can be a safe and effective option for the treatment of intractable pelvic pain with incomplete CES.

바이올린은 아름다운 음색과 풍부한 표현력으로 현악기 가운데 중요한 위치를 차지하고 있다. 그러나 바이올린 연주를 처음 시작하는 초보자들에게는 정확한 연주를 하기가 쉽지 않다. 이는 연주 시 활의 힘과 활을 켜는 속력 그리고 활과 현과의 접촉점 및 현을 집는 손가락 위치의 부정성에서 기인된다. 따라서 본 논문에서는 이 점을 해결하기 위해 전문 바이올리니스트의 운궁법에 대한 데이터베이스를 사전 구축하고, 연주자가 실제 바이올린을 켤 때 얻어지는 데이터를 구축된 데이터베이스와 실시간으로 비교하고 그 결과를 퍼지 Logic을 사용한 성능평가함수로 성능평가를 한 후 Monitor상에 결과를 보이도록 하였다.

According to the regulation of IMO, oil discharge from ships is allowed under 15ppm only and an oil filtering equipment is essential. However, for large ships using heavy fuel oil of over S.G 0.98 and viscosity 380cSt and system oil, it has been in difficulty to process with existing filtering type of oily water separator. A parallel plate type oily water separator which is one of gravity type separators can be used as an assistant equipment for the oil filtering system to meet the present IMO standard of 15 ppm, because it is an efficient method in dealing with a large amount of rich oil with high specific gravity. This work is focused on the fundamental investigation of the performance of the plate type oily water separator by visualization method and PIV(Particle Image Velocimetry) measurement to acquire multi-point velocity data simultaneously. The experimental results showed that the space of the plates acts a significant role in separating process and it was found that an important point to minimize a vortex flow is to flow a large amount of fluid in space of the plates in order to promote the efficiency of separation.
