異状死の発生は,冬季に多く,春から夏季にかけては少なくなる.例年の冬季の増加は,高齢者の入浴中やトイレ内での死亡が多くを占め,寒冷環境の影響が大きい.しかしながら,2007(平成 19)年 8 月及び 2010(平成 22)年 7 月に検案数の異常な増加があった.この原因は,梅雨明け後の小雨,かつ記録的な猛暑の影響から熱中症による死亡の急増であると判断されたので,監察医務院から関係省庁及び報道関係に対して「熱中症の予防」を訴える警鐘を鳴らした.本稿では,監察医務院で取り扱った熱中症の実態を紹介すると共に,熱中症死の死体現象,その診断の実態について解説し,併せて寒冷環境の死亡に与える影響についても紹介する.

Background: Although direct oral anticoagulants (DOACs) are widely used in Japanese patients with atrial fibrillation (AF), large-scale investigations into their use, with suitable follow-up times and rates, are lacking. Methods and Results: The SAKURA AF Registry is a prospective multicenter registry created to investigate therapeutic outcomes of oral anticoagulant (OAC) use in Japanese AF patients. We conducted a study involving 3,237 enrollees from 63 institutions in the Tokyo area being treated with any of 4 DOACs (n=1,676) or warfarin (n=1,561) and followed-up for a median of 39.3 months (range 28.5–43.6 months). Analyses of 1- and 2-year follow-up data available for 3,157 (97.5%) and 2,952 (91.2%) patients, respectively, showed no significant differences in rates of stroke or systemic embolism (SE), major bleeding, and all-cause mortality for DOAC vs. warfarin users (1.2 vs. 1.8%/year, 0.5 vs. 1.2%/year, and 2.1 vs. 1.7%/year, respectively). Under propensity score matching, the incidence of stroke or SE (P=0.679) and all-cause death (P=0.864) remained equivalent, but the incidence of major bleeding was significantly lower (P=0.014) among DOAC than warfarin users. Conclusions: A high follow-up rate allowed us to obtain reliable data on the status of OAC use and therapeutic outcomes among AF patients in Japan. Warfarin and DOACs appear to yield equivalent 3-year stroke and all-cause mortality rates, but DOACs appear to reduce the risk of major bleeding.

Advancing the digital technologies in Graphic Arts, standardization for total printing process is required to reduce the loss occurred in printing process. Moreover, the standardization is considered to be a significant issue to accomplish building CMS environment. To achieve the standardization, especially in printing stage, the printing color control system comes up first as an essential tool. In this literature, mainly what you can do with KOMORI's printing color control system "PDC-S and net Version" as supporting tool for standardization is addressed.

The succession of bacterial populations in the large bowel of healthy infants was examined during the first week of life. The predominant fecal organisms by theend of the first week were bifidobacteria, bacteroides, clostridia, enterobacteria, and streptococci. The bacteria isolated from the feces of breast-fed and bottle-fed infants, aged about one month, were identified. The composition of the fecal bacteria varied according to the infant's diet. The organism that showed the highest count and the highest frequency of occurrence in both groups was Bifidobacterium breve. The counts and incidences of Clostridium paraputrificum, C. perfringens, and Bacillus subtilis, the counts of C. clostridiiforme, Bacteroides vulgatus, Veillonella parvula, Lactobacillus gasseri, Escherichia coli, Streptococcus bovis, Enterococcus faecalis, and E. faecium and the incidences of C. difficile, C. tertium, and Pseudomonas aeruginosa in the bottle-fed infants were significantly higher than those in the breast-fed infants. A comparison of the fecal bacteria in healthy adults and aged persons was also made. The numbers of B. distasonis, B. vulgatus, B. adolescentis, and B. longum in the healthy adults were significantly higher than those in the aged persons. A significantly increasednumber of Clostridium paraputrificum was found in the feces of senile subjects. Subsequent studies on development of intestinal microflora in pigs, dogs, rats, and chickens were also described. These dramatic changes in the development of gut colonization were probably brought about by bacterial interactions, as well as changes in food.

Background: It is known that physical activity affects glucose metabolism. However, there have been no reports on the influence of physical activity earlier in life on subsequent glucose metabolism. Therefore, we analyzed the influence of physical activity in earlier decades of life on insulin resistance in middle aged and older residents in Japan.Methods: The subjects were 6,883 residents of Okazaki City between the ages of 40 and 79 years who underwent physical examinations at the Okazaki City Medical Association Public Health Center from April 2007 through August 2011. They gave informed consent for participation in the study. Data on individual characteristics were collected via a questionnaire and from the health examination records. Fasting blood glucose and insulin levels were used to calculate the homeostatic model assessment of insulin resistance (HOMA-IR). HOMA-IR >1.6 was considered to indicate insulin resistance for the purpose of logistic regression models.Results: The study sample included 3,683 men and 3,200 women for whom complete information was available. For those who exercised regularly throughout their teens to their 30s–40s, the odds ratio for having insulin resistance was 0.75 (95% confidence interval [CI], 0.58–0.96) for men and 0.76 (95% CI, 0.58–0.99) for women after adjusting for other variables, including age, body mass index, and present physical activity. A linear trend was also observed in both men and women.Conclusions: Subjects who have exercised regularly in the early decades of life are less likely to have insulin resistance later in life.

Distribution and retention of tritium in various tissue of a rat after administration of tritiated water (HTO) was investigated during about 100 days. Tritium incorporated into the body was rapidly and uniformly distribution in the whole body and excreted immediately with a biological half-life of 3.5 days for almost all the tissues. However, excretion of tritium incorporated into the tissue constituents was relatively slow and the retention curves were considerably different from tissue to tissue. At the end of this experiment, the highest concentration of total tritium was observed in the fat tissue, followed by brain and muscle. These results suggested that the intake of tritium from HTO into organic compounds and the excretion of tissue-bound tritium would be related to metabolic activity of the tissue. This prediction was reinforced by the experiment on age dependence. The radiation dose to each tissue after the administration of 6.0 μCi/g body weight of HTO ranged from 2.0 to 9.5 rem, which was the highest in blood and the lowest in fat tissue. Contribution from tissue-bound tritium was within 10% of the dose from total tritium for each tissue, except for fat tissue which was 64%.

An increase in gill raker numbers in skipjack tuna (Katsuwonus pelamis) was observed during the development of juvenile and young stages (26–187 mm in standard length (SL)). Examination of 104 individuals showed obvious increments in number with growth, until 80–100 mm SL. Subsequently, numbers increased slowly (to 59 in the largest specimen), indicating that gill raker development in skipjack tuna is slower than in other scombrid fishes, such as Thunnus. However, gill raker numbers in juvenile and young skipjack tuna stages remain a useful taxonomic character.

In National Government Parks, a large number of exhibition facilities have been constructed and are managed and operated for purposes such as introduction of projects related to parks and open green space, popularization and education activities related to the nature and culture of the region, etc. Issues for these exhibition facilities include renewal of exhibits, specialization of content, and the like. Study of efficient/effective management and operation techniques referring to case studies of museums, which are similar facilities, is considered effective in responding to these issues. In this research, the date of establishment, area, items displayed, condition of installation of fixtures and furniture of the exhibition facilities, and the purpose, period, location, content, and management and operation of the operation system, etc. of permanent exhibits and thematic exhibits were arranged, and the features and effects of exhibits in National Government Parks were analyzed and considered from the viewpoint of museum-like functions.

The demand-supply imbalance on electric power system is absorbed by system frequency variations, before the LFC controls. Since frequency fluctuations are common in all linked blocks, demand-supply imbalance of one block is absorbed by another block too. Demand-supply imbalance arises in another block simultaneously, and is absorbed by the former block. These mutual supports have a direct effect on linkage power fluctuations. The size of this self-regulation is regarded as proportional to the size of frequency fluctuation and the ratio of the former to the latter is nearly proportional to the block capacity. But, at a short period variation range, there is a fear that such a proportional relation will be biased by linkage position. We analyze this point, and reached the following conclusions. First, we can prove the existence of self-regulation bias theoretically and point out that the bias has some effect on linkage power fluctuations at short period variation range. Second, we apply this analytical method to 4 blocks-linked system of Japan, and compare the theoretical value with measured one. The result indicates no correlation among demand fluctuations of those blocks which are presupposed for calculation of the theoretical values; among several blocks is found some ununiformity of the smallest unit size of demand power variations.

多くの西アフリカ沿岸都市同様, セネガルの首都ダカールはいくつもの海岸災害を起こしやすい. その中で最も深刻な災害は海岸浸食である. ダカールの地質は主に第三紀火成岩とそれを覆う第四紀堆積物からなっており, 自然の過程に逆らった人間活動の結果, とくにそのような堆積物に覆われた地域が重大な浸食にあってきた.自然現象による海岸浸食は荒波の時期に絶え間なく続き, うねりと潮汐波の2つの波の形態によって起こる. 人間活動による海岸浸食への悪影響は, 粗末な都市計画と人口過剰の累積効果である. セネガルのほとんどの経済活動は, 活発な地域であるダカールに集中しており, 生計を立てるために多くの人々が移り住んでいる. このような過度の人口集中が建設ブームを引き起こ し, 砂浜や砂丘から砂を過剰に取り去ってしまった. その結果, 浸食と堆積のバランスが変化したために陸地の低下が始まり, 最終的に大規模な海岸浸食を引き起こした.
