Even though high NA, Hyper SIL system easily decline the optical performance even a little alignment error. Not only to overcome this instability but to maintain the high NA gain, we suggest a new system (Optimum SIL) which is a combination of each advantage of Hyper SIL and Hemi SIL. Simulation results shows that Optimum SIL system has much higher tolerance to various performance-lowering factors than Hyper SIL system even with a relatively small NA resignation.

The current study used the critical science paradigm to explore the kinds of oppression experienced by the families of patients in hospitals, and to suggest how the practices should be changed for problem solving. Ethnographic observations and individual interviews were peformed for data collection from the 25 family members of critically ill patients. The results revealed the powerlessness of patients' families caused by multiple oppressions. They were struggling with family-unfriendly hospital systems, negative interactions with medical staff, limited supports from health care systems, and their own resignation to fate. Strategies were discussed to facilitate changes in institutional, humane, policy, and religious/spiritual aspect. The study findings will contribute to promoting the rights of patients' families.

대부분의 기업에서는 우수한 인적 자원의 유출을 방지하기 위해 직원들이 이직 및 퇴사하는 이유를 연구한다. 이에 기업은 직원이 퇴사하기 전에 면담을 하거나 설문조사를 통해서 연구에 필요한 데이터를 얻는다. 하지만 설문조사에서는 직원들이 직장 생활을 하는 데에 불리할 수도 있는 의견을 드러내려고 하지 않아 정확한 결과를 얻기 힘든 것이 현실이다. 한편, 한국노동연구원에서 발표한 자료에 따르면 기업이 요구하는 최소 학력 수준과 직원의 학력 수준 간의 차이가 클수록 이직 경향이 커진다. 따라서 본 연구에서는 한국노동연구원의 자료에 착안하여, 직원이 가지고 있는 객관적 데이터인 전공, 교육수준, 재직 중인 회사 유형 등의 데이터를 기반으로 직원의 퇴사 여부를 예측하고자 한다. 퇴사 예측 모델을 생성하기 위해 Decision Tree, XGBoost, kNN, SVM을 활용하였으며 각각의 성능을 비교했다. 이 결과, 지금까지 설문조사로 진행되었던 연구에서 파악하지 못한 다양한 요인을 알아낼 수 있었다. 이를 통해 기업이 퇴사 예측 모델을 이용하여 직원이 퇴사하기 전에 미리 이를 인지하고 방지하는 데에 도움을 줄 수 있을 것으로 예상된다.

This study explored, through informal, conversation-type interviews, how college students relate to science in general as well as to two specific socioscientific issues: human cloning and animal dissection/experimentation. How students "relate" includes what kinds of attitudes they have toward science and socioscientific issues, how seriously they consider and want to engage with these issues, and how they express their opinions or make a decision. The sample (16 college students) was heterogeneous in terms of academic background, ethnicity, and school year. Each interview lasted for about one hour with audiotaping. Results indicated that most participants immediately brought in their own values and feelings in implicit or explicit ways. However, the depth of their personal engagements varied. Most of the participants either did not take socioscientific issues seriously or merely quoted their own values in resignation, seemingly not able to deal with the issues and overwhelmed by many other aspects of the issues. By reflecting on the participants' reactions, the discussion addresses some of the larger issues for current secondary science teaching that involve raising responsible democratic citizens.

We discovered various sides of Lee Jema's tenure as the governor of Jinhae by looking at recently found historical materials of the central government of Joseon. Lee Jema went to his appointed post in Jinhae in February of 1887 and was replaced before the termination of his office in June of 1888. Since his replacement did not immediately arrive at Jinhae, Lee Jema continued to perform his duties until the first half of 1889. The difference between the date of his resignation and the arrival of his replacement reveals why various historical materials disagree about when he left office. After Lee Jema's official resignation in June of 1888, he was appointed to the honorary posts of Naegeumjang and Cheomji, which indicates the termination of his career as an official. Two superior officials conducted job assessments on Lee Jema three times during his service (once every six months) and these are the rare evaluations which were performed during his lifetime. Lee Jema was highly regarded in terms of job competency by two superiors in succession, which was unique for a local government official in the late Joseon dynasty. One of the job assessments referred to the potential of his performance as an official which usually implied that he was a suitable candidate for higher rank. This might have derived from Lee Jema's study of statecraft. Lee Jema's love for the people as an official was also mentioned in one of the job assessment reports. This is borne out by his quelling the revolt of Hamheung Province in 1896.

The medical insurance system has been adopted in 1989. Since then, the utilization of medical care services has increased rapidly. It appears that the medical institution needs more nursing manpower such as nurses and nurse aides to meet an increased demand for medical care for the residents. However, the medical care clinics run by a medical practitioners has a more shortage of nursing manpower than hospitals. The purpose of this survey was to analyze the current employment status and to obtain an opinion on the improvement of utilization such as recruitment and retention of nursing manpower. The questionnaire sent to the private physician and the response rate was 28.7% ; 87 out of 300 physicians. 82.6% of the respondents employed nurses aides rather than nurses and an average number of employees per clinic was 2.5 persons. Most physicians had difficulties in recruiting nursing manpower. It took more than one month for replacement on average, therefore, they were suffering from giving good continual care for the patient and also high resignation of nursing personnel. The low wage, long working hours, hard work and lack of incentives are the biggest reasons for the difficulty in recruiting and retaining of the nursing personnel obtained for the clinics survey. The above mentioned problems would be solved in the near future by changing those difficulties. In the meantime, the private physicians are marking an effort to retain the nursing personnel by keeping a relationship of the private physician's cooperatives.

Purpose: The purposes of this study were to explore and describe the use of restraint on patients and to generate a grounded theory of how the use of restraint affects patients who have been restrained. Methods: Interview data from seven patients with physical restraint was analyzed using the Strauss and Corbin's grounded theory method. Data were collected and analyzed simultaneously. Unstructured and in-depth interviews were conducted retrospectively with patients recalling their memories of ICU following their transfer to general unit. Results: 'Safety belt' was emerged as a core category and it reflected that physical restraint provided a sense of security to patients. On the basis of core category, a model of the experience process of restrained patients in ICU was developed. The experience process were categorized into four stages: resistance, fear, resignation, and agreement. Stages of these proceeds appeared to have been influenced by the nurses' attitude and caring behavior such as the frequency of nurse-patient interaction, repetition of explanation, and empathetic understanding. Conclusion: These findings indicate that patients have mixed feelings towards restraint use, although negative feelings were stronger than positive ones. The result of this study will help nurses make effective nursing intervention.
