  • Three kinds of survival rates are generally used depending on the purpose of the investigation: overall, cause-specific, and relative. The differences among these 3 survival rates are derived from their respective formulas; however, reports based on actual cancer registry data are few because of incomplete information and short follow-up duration recorded on cancer registration. The aim of this study was to numerically and visually compare these 3 survival rates on the basis of data from the Nagasaki Prefecture Cancer Registry. Subjects were patients diagnosed with cancer and registered in the registry between 1999 and 2003. We calculated the proportion of cause of death and 5-year survival rates. For lung, liver, or advanced stage cancers, the proportions of cancer-related death were high and the differences in survival rates were small. For prostate or early stage cancers, the proportions of death from other causes were high and the differences in survival rates were large. We concluded that the differences among the 3 survival rates increased when the proportion of death from other causes increased.

  • The sudden death syndrome has been encountered in Korean native cattle in a small island village of Yeochun, Chonnam since 1984. In an effort to diagnose the causes of the condition, 10 calves were purchased and shipped to the village to be reared conventionally. During the period of April 1988 through March 1989 the animals were clinically examined every month, samples of blood and feces collected and examined. Soils, plants and water samples were analysed, and necropsy was performed on two calves which died during the period. No abnormalities were found by clinical examination. Soil, plant and water analysis did not reveal any abnormalities which could be related to sudden death. One of the 2 dead calves was fallen and suffocated to death after the right hock was tied by rein. The other had a torsion In jejunum after plowing. Epidemiological examination revealed that two calves of one farmer died in one day from bloat. Authors explained the results and asked the people in the island to improve management of the animals, and no more sudden death occurred for 2 years.

  • The median ages at death from cancers between 1985 and 2005 were calculated to demonstrate that inherent anticancer mechanisms may be a common pathway for different cancers. Seventy-eight patients with gastric, liver and lung cancers, were recruited in the solid cancer group. The leukemia group consisted of 31 patients with three main types of leukemia. The controls were 100 healthy individuals. The samples were typed using an HLA-DR/DQ PCR-SSP typing kit. The results showed that the median ages at death from all causes were 64.7 years in 1985 and 70.1 years in 2005. The range of the median ages at death from all cancers was similar to the corresponding value for deaths attributed to all causes. The frequency of $DRB1^*03$ was 9.6% in the solid cancer group and 3.0% in the control group (p<0.05). The frequency of $DRB1^*04$ in the leukemia group were significantly lower than that of the control (p<0.05). $DRB1^*13$ and $DRB1^*06$ frequencies in the leukemia group were significantly higher than those of the controls (p<0.05). It is suggested that inherent anti-cancer mechanisms may be a common pathway for different cancers and are associated with the immune system and HLA.

  • The KSA caused an error in deriving the statistical measurement items due to the misconfiguration of the safety variables and sub-modules that constitute the safety statistics framework for external causes of death, and pathogenesis, without considering the academic classification system of the field and area of the disaster/accident. By naming it as a mechanism, it was analyzed that the result of poor statistical validity has arrived. Therefore, in this study, by changing the safety parameters according to the WHO safety definition and setting the sub-modules appropriately, the categories of falls, drowning accidents, and accidents exposed to inanimate mechanical forces are classified as accidents at industrial sites and work in daily life. As a result, by systematically re-establishing the complex group of statistical items of the NSO by deriving the field of disasters/accidents according to the nature of the source of external causes of death and setting the relevant domains academically, statistical validity gets better and It is anticipated to play an important role in determining the direction of safe investment.

  • Purpose: Studies have been conducted on the prevalence and infant mortality rate of congenital anomalies; however, studies on child mortality are rare. Therefore, we evaluated the characteristics of deaths associated with congenital anomalies among children born in Korea who died within 5 years of age. Methods: Birth-to-death cohort linked data of children under the age of 5 years from 2010 to 2013, and statistical data on the cause of death by age from 1999 to 2019, both provided by the Korea National Statistical Office's Microdata Integrated Service, were retrospectively investigated. We investigated the trends and characteristics of mortality associated with congenital anomalies. Results: Among 1,858,945 children, 6,510 children who died were under 5 years of age, and among them, 1,229 deaths were associated with congenital anomalies, while 5,281 deaths were due to other causes. Deaths associated with congenital anomalies accounted for 18.9% of all deaths. When comparing congenital anomalies by systems, anomalies of the cardiovascular system (52.6%) were the most common. The mortality rate associated with congenital anomalies and those of other causes showed similar declining trends in 21 years. Conclusion: The mortality rate of congenital anomalies during the first 5 years of life did not increase differently from the prevalence of congenital anomalies but rather decreased. Deaths associated with congenital anomalies accounted for 20.5% of all infant deaths and 12.1% of child deaths, since the major causes of death in infants and children are slightly different, continuous and careful monitoring is required.

  • Purpose: To improve professional intensive care by analyzing admission causes, causes of death, disease conditions, and treatment processes in patients with hematological malignancies admitted to intensive care units (ICUs) in South Korea. Methods: This was a retrospective study approved by IRB, and conducted on admission with 559 adults, in the hematology ICU of a hospital located in Seoul. The study was carried out from April 2009 to March 2012. Data were analyzed using SAS. Results: Pneumonia was the most frequent cause of ICU admission and death, followed by sepsis. The condition at discharge was death (53.6%), recovery (39.9%), or hopeless (5.1%). Mortality of patients in states of incomplete remission was higher than that of patients with complete remission and of patients with multiple myeloma, severe aplastic anemia, and lymphoma. Conclusion: Results show that pneumonia and sepsis are the most frequent causes of ICU admission and for the death of patients with hematological malignancies. The most frequent status at discharge of patients with hematological malignancies was death (53.6%), with mortality of patients at Incomplete Remission status, of mechanically ventilated patients, and of patients on continuous renal replacement therapy (CRRT) being higher than others.

  • In order to examine cause-specific mortality in Korea by comparing mortality of Japan, various mortality indicators are calculated using 1995 of ficial statistics of twonations. The mortality measures are cause-specific mortality rate by sex, age, andmarital status, cause-specific age-standardized death rate and potential years of lifelost, and their ratios by sex and nation. Items of major causes of death include allcauses (total deaths),tuberculosis, malignant neoplasm, diabetes mellitushypertensive diseases, heart diseases, cerebrovascular diseases, liver diseasestransport accidents, and suicide. Major characteristics of mortality in Korea are asfollows . (1) Death rates from most causes except suicide are higher in Korea thanJapan and especially death rates from tuberculosis, hypertensive diseases, liverdiseases, and transport accidents are higher for economically active Koreans : (2)Death rates from tuberculosis, liver diseases, transport accidents, and malignantneoplasm are salient for Korean children (3) Sex-differentials in mortality fromliver diseases, tuberculosis , and transport accidents are large for economically activeKoreans, because male mortality is higher than female mortality : (4) Suicide ratesare lower for economically active males, and higher for females aged 10s and 20s inKorea than Japan : (5) Death rates are highest f3r divorced or widowed under 45years of age depending on causes, but death rates from all causes are highest fornever-married of the age 45 and over in Korea : and (6) Sex-differentials inmortality are greatest for widowed in Korea and for divorced in Japan.

  • In the bacterial community, unicellular organisms act together as a multicellular being. Bacteria interact within the community and programmed cell death (PCD) in prokaryotes is a sort of altruistic action that enables the whole population to thrive. Genetically, encoded cell death pathways are triggered by DNA damage or nutrient starvation. Given the environmental and bacterial diversity, different PCD mechanisms are operated. Still, their biochemical and physiological aspects remain unrevealed. There are three main pathways; thymineless death, apoptosis-like death, and toxin-antitoxin systems. The discovery of PCD in bacteria has revealed the possibility of developing new antibiotics. In this review, the molecular and physiological characteristics of the three types of PCD and their development potential as antibacterial agents are addressed.

  • Objectives: The objective of this study was to assess the relationship between systolic and diastolic blood pressure (SBP, DBP) and the risk of death from specific causes other than cardiovascular diseases. Methods: We calculated the risk of specific death by SBP and DBP categories for 506 508 health examinees in 2002-2003 using hazard ratios (HRs) and 95% confidence intervals (CIs) in a Cox proportional hazards model. Results: Compared to normal levels (SBP <120 or DBP <90 mmHg), stage I systolic and diastolic hypertension (SBP 140-159, DBP 85-89 mmHg, respectively) were associated with an increased risk of death from diabetes mellitus, alcoholic liver disease, and renal failure (HR, 1.83; 95% CI, 1.51 to 2.22; HR, 1.24; 95% CI, 1.06 to 1.46; HR, 2.30; 95% CI, 1.64 to 3.21; HR, 1.67; 95% CI, 1.27 to 2.20; HR, 1.99; 95% CI, 1.41 to 2.81; HR, 1.31; 95% CI, 0.99 to 1.73, respectively), but a decreased risk of death from intestinal pneumonia (HR, 0.64; 95% CI, 0.42 to 0.98; HR, 0.59; 95% CI, 0.39 to 0.91). Only stage II systolic hypertension (SBP ${\geq}160mmHg$) was associated with an increased risk of death from pneumonia, liver cirrhosis, and intestinal ischemia (HR, 1.54; 95% CI, 1.19 to 1.98; HR, 1.46; 95% CI, 1.00 to 2.15; HR, 3.77; 95% CI, 1.24 to 11.40, respectively), and stage I and II diastolic hypertension (SBP 140-159 and ${\geq}160mmHg$) were associated with an increased risk of death from intestinal ischemia (HR, 3.07; 95% CI, 1.27 to 7.38; HR, 4.39; 95% CI, 1.62 to 11.88, respectively). Conclusions: An increase in blood pressure levels may alter the risk of death from certain causes other than cardiovascular diseases, a well-known outcome of hypertension, although the mechanism of these associations is not well documented.

  • Improvements in various health indices have been ushered in, along with soaring economic growth in the last few decades in Korea. Life span of Koreans at present stands at somewhere around age of seventies. It seems of worth to elucidate some facets of health profile of historic Koreans during Yi dynasty encompassing about five hundreds years between the 14th and 19th century. Datas on health of historic Koreans are meager with exception for sovereigns for whom royal archives have been preserved intact through centuries. Though the health environments for monarchs are, no doubt, incomparable to that of the grassroot levels during the same period, health profile of monarchs would facilitate to assess health indices for historic Koreans during Yi dynasty. Arithmetic average of life span of 25 consecutive Kings(omitted the last two Kings under Japanese control) is 44.6 years of age 81 year old for King Yongjo and 16 year old for King Danjong, representing two extremes. The principal causes of death are septicemia, subsequent to infections of soft tissue and ether organs(8 in number, one-thirds of all). Secondly, both epidemic disease and vascular accidents caused deaths of three Kings each. Two kings succumbed to diabets and one suicide. The causes for the remainder, eight kings are hardly ciarified. The monarchs who contributed in establishment of new Yi dynasty with highspirited and disciplined survied beyond their fifties and sixties. In contrast, those who reigned during mid - era of the dynasty at its culmination succumbed to death in their young adulthood, most likely due to their indulgence in court life.
