This paper proposes a method to determine the optimal utilizations of the UNIX systems. This method is developed using the definition-the optimal utilization is the maximum allowable utilization. In other words, the optimal utilization is the maximum utilization that can be allowed by users while providing tolerable response time. As the tolerable response time increases, the optimal utilization increases. Therefore, the optimal utilization is obtained at the maximal value of tolerable response time. Our analysis shows tolerable response time is achieved when the average of the trivial response time is less than 0.24 seconds for a given service objective. It also shows the optimal utilization consists of three components-%wio, and %usr. By way of example, the optimal utilizations of a machine (IBM 3081) running under the UNIX operating system are computed are computed using the proposed method.

연명의료결정법의 정식 명칭은 '호스피스 완화의료 및 임종 과정에 있는 환자의 연명의료 결정에 관한 법'이다. 이 법은 호스피스 완화의료에 대한 것과 환자의 연명의료 결정에 대한 것을 규정하고 있다. 특히, 후자의 연명의료결정에 관한 부분은 법제정 과정에서 법 종교 의료 윤리 등 다양한 분야에서 논박이 있었지만 2018년 2월 4일부터 시행되고 있다. 법학에서는 이 법이 생명이라는 법익과 관련되어 있어 형사법적, 민사법적으로 중요한 의미를 갖는다. 이 법이 탄생되기 위해 두 번의 변곡점이 있었다. 첫째, 1997년 '보라매병원 사건'에서 의사를 작위에 의한 살인방조죄로 판결한 사건 둘째, 2009년 '김 할머니' 사건에서 회생할 수 없을 경우 가족 등이 진술한 환자 의사에 따라 연명 의료를 중단할 수 있다는 대법원 판결이다. 연명의료결정법은 헌법상 생명권과 자기운명결정권이라는 기본권 충돌이 발생한다. 두 기본권이 서로 상충 할 때에는 어떠한 기본권을 우선해야 하는지가 실질적으로 문제되는데, 이익형량을 통한 규범의 조화로운 해석을 통해 해결해야 한다. 또한 이 법의 흠결과 문제점을 고찰하여 개정작업이 진행되어야 한다.

This study has been performed to identify meanings of good deaths among 350 old people aged 65 from September, 2010 until February, 2011. In this study, the subjects were asked about good meanings of death based on qualitative study of free format, and their statements were categorized into similar content areas. The results show that first, the subjects felt that the good death is a dignity death not weighing burdens to others, memorized as a good life, until th end of my life, a death receiving at home, comfortable death, a death like a sleep, with out pain, not long, a prepared process, a death after doing my best, receiving after doing my best, death after offering benevolence to others, within my beliefs, and finally a good death is after seeing good life of my descendent. These 16 free answers were also categorized into 6 meaningful areas such as considering others, at my home, comfortable scene, prepared, and death after living my wanted time.

This is a descriptive study on the perception and attitude toward DNR in adults. Structured questionnaires were used and 210 subjects were studied. In recognition of DNR, DNR was helpful for 'a comfortable dying(64.3%)'. The need for DNR in situation investigated 'For dignified dying (41.3%)' and 'to alleviate patient suffering(23.9%)'. Respondents who do not agree with DNR are shown 'Because legal issues can arise(61.7%)', 'Because human dignity is the life-sustaining priority(16.7%)'. In the attitude toward DNR, the most significant result was 'I want to know if I have an incurable disease (4.21).' There was no difference in attitudes toward DNR among adults. The DNR is not a method of Withdrawing in lifeprolonging treatment, It should be addressed in a comprehensive context in which human beings exercise autonomy over the process of dying and death.

The first hospice care center in Korea dates back to the East West Infirmaries (Dongseodaebiwon in the Korean language) of the Goryeo period in the early 11th century. It has been 50 years since hospice care was introduced in Korea. Initially hospice care was provided in the private sector, including those with a religious background, and its development was slow. In the 1990s, related religious organizations and academic associations were established, and then, a full-swing growth phase was ushered in as the Korean government institutionalized hospice care in the early 2000s. As a result, enhanced quality of hospice care service could be provided, which meant better pain management and higher quality of life for late stage cancer patients and their families. Still, the nation lacked a realistic reimbursement system which was needed to for financial stability of the affected patients. However, the national health insurance scheme began to cover hospice palliative expenses in 2015. In 2016, the Act on Decisions on Life-Sustaining Treatment for Patients in Hospice and Palliative Care or at the End of Life was legislated, allowing terminally-ill patients to refuse meaningless life-sustaining treatments. As the range of diseases subject to hospice palliative care was expanded, more challenges and issues need to be addressed by the service providers.

According to the current act of Decision-Marking in Life-Sustaining Medicine, the decision to withhold or discontinue life-sustaining treatment is primarily based on the wishes of a patient in the dying process. Decision-making regarding life-sustaining treatment for these patients is made by the patient, if he or she is conscious, directly expressing his/her intention for life-sustaining treatment in writing or verbally or by writing an advance medical directive and physician orders for life-sustaining treatment. It can be exercised. On the other hand, if the patient has not written an advance medical directive or physician orders for life-sustaining treatment, the patient's intention can be confirmed with a statement from the patient's family, or a decision to discontinue life-sustaining treatment can be made with the consent of all members of the patient's family. However, in the case of an unrelated patient who has no family or whose family is unknown, if an advance medical directive or physician orders for life-sustaining treatment are not written before hospitalization and a medical condition prevents the patient from expressing his or her opinion, the patient's will cannot be known and the patient cannot be informed. A situation arises where a decision must be made as to whether to continue or discontinue life-sustaining treatment. This study reviewed discussions and measures for unbefriended patients under the current law in order to suggest policy measures for deciding on life-sustaining treatment in the case of unbefriended patients. First, we looked at the application of the adult guardian system, but although an adult guardian can replace consent for medical treatment that infringes on the body, permission from the family court is required in cases where death may occur as a direct result of medical treatment. It cannot be said to be an appropriate solution for patients in the process of dying. Second, in accordance with Article 14 of the Life-Sustaining Treatment Decision Act, we looked at the deliberation of medical institution ethics committees on decisions to discontinue life-sustaining treatment for patients without family ties.Under the current law, the medical institution ethics committee cannot make decisions on discontinuation of life-sustaining treatment for unbefriended patients, so through revision, matters regarding decisions on discontinuation of life-sustaining treatment for unbefriended patients are reflected in Article 14 of the same Act or separate provisions for unbefriended patients are made. It is necessary to establish and amend new provisions. In addition, the medical institution ethics committee must make a decision on unbefriended patients, but if the medical institution cannot make such a decision, there is a need to revise the law so that the public ethics committee can make decisions, such as discontinuing life-sustaining treatment for unbefriended patients.

Cancer chemoprevention refers to the use of natural or synthetic substances to prevent initiational and promotional events that occur during the process of carcinogenesis. Thesium Chinese Turczaninow aqua-acupuncture solution (TCTAS) and Astragli Radix aqua-acupuncture solution (ARAS) were tested as the cancer chemopreventive agents using biochemical markers of carcinogenesis. The effects on the inhibition of phorbol 12- myristate 13-acetate(TPA)-induced free radical formation in HL-60 cells and the inhibition of polyamine metabolism were measured. There is significant inhibition of TAP-induced free radical formation in human leukemic cells with cells with ARAS. Proliferation of Acanthamoeba castellanii was inhibited by TCTAS and ARAS. TCTAS and ARAS positive in these assays may inhibit the carcinogenesis process and is considered promising cancer-preventing agents.
