  • Life-and-death problem in Go is a fundamental problem to be overcome for implementing a computer Go. To solve it, an important consideration is to find out who surrounds or is surrounded between black and white players. To figure out the boundary between black and white groups, we applied an influence function and a contour tracing algorithm. We found that applying the Moore-neighbor tracing among various contour tracing algorithms can create boundaries, and also suggested the possibility of tremendously reducing the search space of a game tree.

  • In the game of Go, the life-and-death problem is a fundamental problem to be definitely overcome when implementing a computer Go program. To solve local Go problems such as life-and-death problems, an important consideration is how to tackle the game tree's huge branching factor and its depth. The basic idea of the experiment conducted in this article is that we modelled the human behavior to get the recognized first moves to kill the surrounded group. In the game of Go, similar life-and-death problems(patterns) often have similar solutions. To categorize similar patterns, we implemented Kohonen Neural Network(KNN) based clustering and found that the experimental result is promising and thus can compete with a pattern matching method, that uses supervised learning with a neural network, for solving life-and-death problems.

  • Death preparation education is not only preparing for future death but also for happier and meaningful life. Death is a persistent problem faced by all human beings and can be found in connection with the Home Economics(HE) curriculum in that it is a contextual practical problem of individuals and their society. The purpose of the study is to develop the practical problem-based death preparation education teaching-learning plans that can be applied to middle and high school HE subject. As a result of the study, the HE death preparation education program was developed. The program name is 'Death Preparation Education for the Happy Life of Me and Family'. Also, 12 practical problems and the 4 teaching-learning plans were developed. This study is expected to be used as educational materials to allow middle and high school students to take death naturally in their lives and to practice meaningful everyday life for worthy death during the HE classes. As a follow-up study, we propose a study to examine the needs of death preparation education in HE curriculum and to verify the effectiveness of the teaching and learning process of death preparation education in HE class.

  • Until 1970's, mankind have not had definite perspectives on what life after the death was like, which is one of the most important problems for them. Their concepts of the 'life and death problem' has been distorted by the dogmas of the established religions such as Buddhism or Christianity on heaven and hell. But the mankind came to have wholly different views on the life after death thanks to the studies by Raymond Moody Jr. or Elizabeth Quebler-Ross in the mid-1970's. This is the studies on the so-called 'near-death experience(NDE)' which made humankind be able to have scientific approach to the life after death for the first time in their history. What attracts our attention at this point is, however, that the arguements of the NDErs on humman destiny accurately coincide with those of the established religions. In the NDE, most of the experiencers have an encounter with the personal being, symbolized by the Light, through whom they learnt that the devotion(or love) to the neighborhood and the gain of the wisdom are the sole meaning of life. With this result, we can recognize why essential virtues maintained by the established religions until now such as ultimate compassion, unconditional love, forgiveness, or insightful learning are so significant, and that our studies of the NDE are very important in this respect.

  • The life table is a statistical model for life expectancy and reflects mortality experiences exposed to a particular group of people. The following three issues are prerequisite for constructing the life table : a selection of how to estimate the death probability from observed death rates, a graduation method to smooth irregularity of the death probabilities, and an extension method of the death probabilities for oldest-old ages. To construct the life table that is fittest to Korean mortality experiences, we examine five estimation methods such as Chiang's and Greville's for the death probability, three graduation techniques including Beer's and Greville's formulae, and twelve mathematical functions for the extension of death probabilities for oldest-old ages. We also propose a method to resolve the cross-over problem arising from construction the life table.

  • The purpose of this study was to classify the subjectivity type toward death among college students and to understand the characteristics of attitudes and orientations toward death of each type. Since attitudes and orientations toward death is very subjective and unique, Q-methodology was employed in this study. Q-methodology explains the respondent's subjectivity by objectifying his subjectivity for himself. The P-sample consisted of 63 students of K university in D city. Forty statements concerning attitudes and orientations toward death, which developed by Yeun(1999) were utilized for Q-sample. Forty Q-statements were sorted according to the level of agreement or disagreement by forced normal distribution. The Q-sorts by each subjects were coded and analysed with the PC-QUANL program. Five types of subjectivity toward death were identified and labeled. Type 1 'the death- preparation' think frequently about his own death and talk openly about the problem of death with a positive attitude. Type 2 'the life-esteemed' respect the dignity of life most of all. Type 3 'the realty-oriented' do not believe the afterlife and is very concerned about the present life itself instead of thinking about death. Type 4 'the ambivalent' think importantly the aspect of present life and orient the afterlife at the same time. This type reveals opposite attitude of preparing and scaring the death at the same time. Type 5 'the destiny-recipient' attribute death to the destiny and deny suicide. On the basis of this result, the studies about applying and developing educational program on death and hospice care for nurses who care terminal cancer patients and families are needed.

  • Go has a history of more than 2,500 years, and the life-and-death problems in Go is a fundamental problem domain that must be solved when implementing a computer Go. We attempted to determine the numbers of prototypical eye shapes with 3, 4, 5, and 6 eyes that are directly related to the life-and-death problems, and to classify the prototypical eye shapes represented in 4-tuple forms. Experiment was conducted by Monte-Carlo method and point pattern matching. According to the experimental results, the numbers of prototypical eye shapes were 2 for 3-eye, 5 for 4-eye, 12 for 5-eye, and 35 for 6-eye shapes. Further, using a 4-tuple form, we classified prototypical eye shapes into 1 for 3-eye, 3 for 4-eye, 4 for 5-eye, and 8 for 6-eye shapes.

  • There are various understandings how to define death. In the context of medicine, death is defined as the irreversible change of the tissue according to the cessation of circulation and respiration. According to the psychologists, a person need to accept the finiteness as a human being and remain conscious that the death is not avoidable. And they say if a person doesn't regard death as unavoidable reality of life he or she will not confront the humanistic death and after all will die like animals. In philosophy, death is viewed as an unwelcome reality in the end of the journey of life. Sociologists usually understand that the society is the organization composed with living persons and human beings which construct and transmit the culture from generation to generation between the both ends of life and death. In society, the generation is changed, maintained, and developed through the phenomenon of death. Although death of human being is natural event in society, the death of a specific person brings a sense of loss, crisis, and anxiety to the communities like family, regional society, nation, and the world. In this context, death is not confined to personal dimension and it can be regarded as a social problem. It is valuable to summarize the religious perspectives on the meaning of death for the better hospice care. In shamanism, there are basic idea that although the flesh of human being disappears, soul never die. If human dies, the flesh of human being disappears but soul never disappear and come back to the origin of soul as it is called chaos. So in shamanism, it is said that shaman can solve the mortified feeling, restore the broken harmony, send the soul to comfortable space- the origin, and guarantee the blessing of descendents. Buddhists regard the death as an essential component through the cycles of life. Through this cycle, human being exits as an endlessly transmigrating being and the death is just a restoration to the original status. In Confucianism, the view on the death based on the philosophy of the "Yin and Yang" and "Five elements". In Buddhist tradition, many believers said the philosophy of "Death is the same as life". Unlike usual thoughts that a god governs "life and death" and "fortune and misfortune", Confucianists deny the governance of a god and emphasize the natural orders in which every phenomenon in the world moves according to the principle. Confucianists understand the death as a natural order with this principle. In Confucianists' belief, the essence of human being remains in their own descendent's lives after the death of ancestor, so in Confucianism there is no concept of immortality of the soul. In the history of Christianity, death has been defined generally as the separation of the immortal soul from the mortal body. In the earlier days of Old Testament, the death is regarded as a disappearance of just a flesh and human never disappear and always live in the relationship with God. Later days in Old Testament, we can find the growing concern for the life after the death because of the entrance of the theodicy. In the New Testament, the death is not regarded as the normal process of the human life and regarded as the abnormal status in which death come to human because of sin as a decisive factor and it should be conquered. In fact, the most of us afraid death because not of the fear of death itself but of the sense of the emptiness and regrets. so many people often make the monument hoping to live forever. But Christian usually regard this behavior as a sinful act because human being usually think themselves as a master of their life and attempt to become immortal in this kind of trial mortal. But if we live with God, we cannot confront such a condition because we aware limits as a mortal human being and entrust everything on Him and want to live according to His guidance. Therefore, in the Christian tradition, the death is regarded as accomplishment of life, fruits of life, invitation to the eternal life, and the last stage of human growth. For human being, the death is the great step of maturation as a human in the final stage of life.

  • Purpose: This descriptive study investigated the relationship between death awareness and life ethics awareness, according to life stress, among students in the department of paramedics. Methods: General characteristics were identified using means and frequency, and the differences between the two military models were analyzed using the χ2-test and t-test by dividing them into lower and higher groups based on the mean life stress score (99.76 points). Results: Those with high life stress had higher death awareness than those with low life stress at 114.11 points. In contrast, those with low life ethics experienced more severe life stress with a score of 145.61 points (t=-2.609, p=.010)(t=-2.953, p=.003). The death recognition attitude and bioethics according to the degree of living stress-showed a significant correlation between the low and high groups (r=.188, p=.043) (r=.201, p=.042). Conclusion: Paramedic students require education on how to cope with life stress. However, access to education is limited to people living in modern times. As a potential solution to this problem, observing videos on the Internet is recommended. Moreover, we suggest accessing Internet and smart phone applications for advertising/educational purposes.

  • Purpose: This case report was attempted to present the process of the end of life nursing care provided by the visiting nurse. Methods: The subject was a person who was decided the long-term care Grade 1 and received a visiting nursing service, and the service was terminated on the death, and then was selected as a case with the consent of his family. The data were collected through long-term care benefit provision records and interviews with the visiting nurse. The nursing process was presented by applying the Omaha System. Results: The subject had digestion-hydration problems and respiration problems in the physiological domain, and the problems of role change, caretaking/parenting, spirituality, and grief in the psychosocial domain were identified. Depending on the problem, the end of life nursing care was provided to the subject and family members through activities on physical symptoms/signs, dietary management, end-life care, and coping skills. Conclusion: We expect that if the visiting nurse provides anticipatory guidance on the death process, the subject will be able to prepare for death comfortably with the family at home instead of vague fear of death.
