We've reviewed 5,067 cases of claims by death that had occured for about 5 years from January, 1979 to October, 1983. As a result, We came to following conclusions; First, the greater part of deaths above mentioned were due to the Disease of Adult such as the Malignant neoplasm(18.4%), a Heart disease(10.4%), Liver cirrhosis(9.1%) and the Cerebrovascular disease(7.6%) as well as Accidental Death(26.5%), which were occupied by 72% of the whole. Second, classifying them by medical examination or non-medical, deaths in case of non-medical examination showed 80.8% of the. whole. And for age, sections ranging from 40 to 49 and from 30 to 39 took the overwhelming portions by 36.9% and 29.8% respectively, both of which showed 66.7% of the whole. Third, for the period elapsed, deaths within 1 year from the entrance showed 21.3% and that from 1 years to under 2 years, 19.9%. Thus the rate of early death under 2 years stood for 41.2% of the whole. Fourth, for occupation of the insureds, commerce occupied 20.4%, company employees 14.4%, agriculture 13.3%. These three categories marked 48.8% of the whole. From this, it appeared that the accidental death rate of the insured with the risky occupation was much greater than orthers.

All living organisms are destined to die. Cells, the core of those living creatures, move toward the irresistible direction of death. The question of how to die is critical and is very interesting. There are various types of death in life, including natural death, accidental death, questionable death, suicide, and homicide. The mechanisms and molecules involved in cell death also differ depending on the type of death. The dysenteric amoeba, E. histolytica, designated by the German zoologist Fritz Schaudinn in 1903, has the meaning of tissue lysis; i.e., tissue destroying, in its name. It was initially thought that the amoebae lyse tissue very quickly leading to cell death called necrosis. However, advances in measuring cell death have allowed us to more clearly investigate the various forms of cell death induced by amoeba. Increasing evidence has shown that E. histolytica can cause host cell death through induction of various intracellular signaling pathways. Understanding of the mechanisms and signaling molecules involved in host cell death induced by amoeba can provide new insights on the tissue pathology and parasitism in human amoebiasis. In this review, we emphasized on the signaling role of NADPH oxidases in reactive oxygen species (ROS)-dependent cell death by pathogenic E. histolytica.

현시성 자살(exhibitional suicide)이란 죽으려는 의도는 없이 타인에게 "내심의 의사"를 전달할 목적으로 "자살에 이르지 않을 것으로 스스로 인지한 방법"을 사용하였으나 죽음에 이르는 경우를 말하며, 이러한 현시성 자살은 자살과 구별되는 몇가지 특징이 있다. 첫째, 자살의도의 진지성으로 죽고 싶은 마음이 얼마나 분명하고 진지한가에 의해, 둘째, 자살 시도 방법에 의해, 셋째, 자살하는 장소 면에서 구별된다. 즉, 현시성 자살은 죽을려는 목적이 없기 때문에 자살자에 비해 자살의도가 결여되어 있고, 덜 치명적인 방법을 사용하며, 타인에게 쉽게 발견될 수 있는 장소에서 자살을 시도하는 것으로 나타났다. 본 연구에서 경북대학교 법의학교실에 의뢰된 부검 분석 결과 중독사(31.5%)의 경우 적지 않은 수가 현시성 자살자로 추론할 수 있으며, 이러한 현시성 자살은 성인보다는 청소년, 남자보다는 여성에게서 많이 나타나고 있음을 연구 재료 분석 결과에서 간접적으로 증명하였다. 또한 자살 기도자 중 많은 경우가 현시성 자살에 해당됨을 확인하였다. 이러한 현시성 자살은 법적인 관점, 즉 생명보험과의 관계에서는 사고사로 보고 있다. 그러나 현시성 자살을 사고사로 볼 경우 실제 사건에서 입증하기가 어렵고, 보험의 목적과 보험사의 자살면책기간을 둔 취지에 의하면 오히려 현시성 자살을 사고사와 구별하여야 함을 고찰하였다. 현시성 자살은 관계의 부재에서 발생하므로 주변 사람들의 조그마한 관심으로도 이러한 자살을 예방할 수 있다. 심리부검을 통해 테이터화하여 이를 유형화시킴으로써 통계적 목적으로 이용할 수 있고, 앞으로 일어날 유사한 자살을 예방할 수 있을 것이다. 이에 우리나라에서는 현시성 자살에 대한 연구가 아직 없는 상태이므로 더 많은 연구가 필요하다.

Objectives: This study aimed to analyze long-term trends in the contribution of each cause of death to socioeconomic inequalities in all-cause mortality among Korean adults. Methods: Data were collected from death certificates between 1990 and 2004 and from censuses in 1990, 1995, and 2000. Age-standardized death rates by gender were produced according to education as the socioeconomic position indicator, and the slope index of inequality was calculated to evaluate the contribution of each cause of death to socioeconomic inequalities in all-cause mortality. Results: Among adults aged 25-44, accidental injuries with transport accidents, suicide, liver disease and cerebrovascular disease made relatively large contributions to socioeconomic inequalities in all-cause mortality, while, among adults aged 45-64, liver disease, cerebrovascular disease, transport accidents, liver cancer, and lung cancer did so. Ischemic heart disease, a very important contributor to socioeconomic mortality inequality in North America and Western Europe, showed a very low contribution (less than 3%) in both genders of Koreans. Conclusions: Considering the contributions of different causes of death to absolute mortality inequalities, establishing effective strategies to reduce socioeconomic inequalities in mortality is warranted.

The necessity for the investigation of death occurred in military services has no differences to the death of civilians. But the death of military service members under the Universal Conscription System in Korea has special considerations because of hard accessibility by the bereaved family and closed environment of the army. The analysis of the death occurred during military service was carried out and the advanced death investigation system to prevent the death was proposed to prevent the declination of fighting spirit and efficiency and also to restore the solid support by the people. The deaths in the period 1995~2006 were 330 persons in 1995, 359 persons in 1996 and were decreased to 135 persons in 2006. The death caused by safety accidents including vehicle accident, drowning, fall were 56% and by military crimes including suicide, arms, homicide were 44%. The numbers of suicides were 108 persons in 1995 and were decreased to 79 persons in 2006. The numbers of suicides were decreased constantly, but the ratio of suicide to death were increased, so the suicide prevention is more important. The autopsy ratio was increased to 51.5% in 2005 and was much higher compared to the ratio for civilians. The main reasons of complaints by the bereaved family were for regaining reputation, death in harness and reinvestigation of death. The proposals for the advanced death investigation system were as follows. The unnatural deaths including the obvious accidental deaths and homicides have to be defined by the rules. The human resources to perform the autopsy can be supported by the forensic pathologists from medical school. The special training and quality assurance programs are needed for the crime scene investigator. To regain the impaired reputation from the suicide and to support the bereaved family has to be discussed by the government.

To find health problems of Pohang city and to plan the activities to solve them in the situation of localization, the mortalities of the citizens in recent three years from 1994 to 1996 were analyzed from the notices and the certificates of death. The ratios of the notices with the certificates of death In the rural area of Pohang city were higher than those of whole country, the ratios of the urban area were lower than the respective ones, and the ratio differences between the rural and urban area were increasing. It may be that medical facilities are not within easy access of the rural inhabitants. especially in the rural south district with high population density. The proportional mortality indicators(PMI) were lower them those of whole country, much lower in male. So the health status of young aged males is relatively unsatisfactory. The urban inhabitants died in hospitals about two times more than the rural inhabitants and the differences were increasing. It may be that living and housing conditions and socio-cultural differences affected on the places of death. Because it is thought that death in hospitals will be growing at high speed, it is necessary to enlarge facilities fur funeral services. The age standardized mortalities were lower than those of whole country and age grouped mortalities were also the same. There were not any consistent and meaningful findings in the sex ratios of mortality according to the age groups or the calendar years. The mortalities by neoplasms and cardiovascular diseases according to the twenty one major causes of death were rapidly increased from the middle ages in both male and female. So it is important to plan the activities for early detection and health maintenance or promotion by behavior modifications. The leading causes of death were cardiovascular diseases, hypertensive diseases, and traffic accidents. And accidental drowning because of coastal area, liver diseases in male, and low respiratory tract diseases in female were the leading causes of death in part of age groups.

The operation of the nuclear reactor requires accurate and fast methods and techniques for analysing its kinetics. These techniques become even more important when the MOX-fuel is used due to the lower value of delayed neutron fraction 𝛽 for ²³⁹Pu. Based on a Birth-and-Death process review, the mathematical model of thermal reactor core has been proposed different from existing ones. The analytical method for thermal point-reactor parameters evaluation is described within this work. The proposed method is applied for analysis of the unsteady transient processes taking place in a thermal reactor at its start-up or shutdown power change, as well as during small accidental power variation from the rated value. Theoretical determination of MASURCA reactor core reactivity through the analysis of experimental data on neutron time spectra was made.
