International Journal of Advanced Research 12(01) 586-593 2024年1月31日 査読有り筆頭著者This study investigated the impact of emergency food temperature variation andthe presence of privacyon stress with the aim of potentially reducing the stress of living in an evacuation center during large-scale disasters. Salivary amylase activity of the subjects was measured. Results showed no statistically significant impact on stress due to variations in the temperature of emergency food or privacy. However, the survey noted points for improvement, including experiment settings and relationships between subjects, which highlighted the need for future research and surveys. This study is expected to aid with initiatives that reduce stress in evacuation centershowever, more detailed condition settings are required in order to eliminate individual stress level differences.

International Journal of Advanced Research 11(11) 1198-1209 2023年11月30日 査読有り筆頭著者The earthquakes in Kumamoto (2016) and Osaka (2018) in Japan revealed grave repercussions of collapsed block walls, causing fatalities and severe damage. These incidents underscored the need for understanding and mitigating the risk posed by these structures. In response, this study focused on assessing block walls collapse risk. Surveys across Nagasaki, Tokyo, and Chiba scrutinized various factors like rebar presence, wall appearance, and maintenance status using a Japan Concrete Block Association chart. Results revealed alarming statistics: 38% of block walls in Nagasaki posed a danger, with factors like lack of rebar and wall age significantly impacting collapse risk. Comparing regions, earthquake-experienced Kanto had 19% risky block walls versus 38% in less-experienced Kyushu, emphasizing the influence of earthquake awareness on residents perception of block wall risks. Lack of rebar emerged as a primary risk factor across all areas. Considering block walls have a lifespan of 20-30 years, deteriorating rebar due to corrosion poses imminent risks. Urgent surveys and awareness campaigns, especially along school routes, are crucial to prevent tragedies like the young girls death in Osaka. The study emphasizes scholars responsibility to disseminate accurate information about block wall risks during earthquakes. However, challenges persist, such as unclear property ownership, hindering countermeasures even after identifying high-risk walls. Looking ahead, national diagnostic surveys are essential to address the looming danger, especially considering potential seismic events like the Nankai Trough Earthquake. Disaster education must prioritize teaching children about the risks of block walls during earthquakes to ensure their safety.

Journal of medical entomology 2023年10月20日 査読有りFemale sand fleas (Tunga penetrans Linnaeus, 1758, Siphonaptera: Tungidae) cause a severe parasitic skin disease known as tungiasis. T. penetrans is a small flea, measuring less than 1 mm in length. The females of this species burrow into the skin of human and animal hosts and mostly affect the feet. This has led to the anecdotal assumption that T. penetrans, unlike its relatives in the Siphonaptera family, would have a limited jumping ability potentially not reaching higher body parts. However, there is no data supporting this. This study evaluated the jumping capabilities of T. penetrans for height and distance using sticky tapes. The vertical jump of the female T. penetrans ranged from 4.5 to 100 mm with a mean of 40 mm whereas the vertical jump of the male T. penetrans ranged from 1.2 to 138 mm with a mean of 46 mm. The horizontal jump of the female T. penetrans ranged from 18 to 138 mm with a mean of 64 mm and that of the male ranged from 9 to 251 mm with a mean of 80 mm. Based on the literature, fleas of various species have been described as jumping vertically 50-100 times their size and horizontally 5-100 times their size. In this respect, sand fleas appear to have equal expert jumping abilities to their relatives. Their aggregation on people's feet is not likely a result of their poor jumping ability but might be an adaptation to the host's behavior which would require further investigations.

Tropical medicine and health 50(1) 31-31 2022年4月29日 査読有りINTRODUCTION: Snakebites are a major cause of permanent injury and death among poor, rural populations in developing countries, including those in East Africa. This research characterizes snakebite incidence, risk factors, and subsequent health-seeking behaviors in two regions of Kenya using a mixed methods approach. METHODS: As a part of regular activities of a health demographic surveillance system, household-level survey on snakebite incidence was conducted in two areas of Kenya: Kwale along the Kenyan Coast and Mbita on Lake Victoria. If someone in the home was reported to have been bitten in the 5 years previous to the visit, a survey instrument was administered. The survey gathered contextual information on the bite, treatment-seeking behavior and clinical manifestations. To obtain deeper, contextual information, respondents were also asked to narrate the bite incident, subsequent behavior and outcomes. RESULTS: 8775 and 9206 households were surveyed in Kwale and Mbita, respectively. Out of these, 453 (5.17%) and 92 (1.00%) households reported that at least one person had been bitten by a snake in the past 5 years. Deaths from snakebites were rare (4.04%), but patterns of treatment seeking varied. Treatment at formal care facilities were sought for 50.8% and at traditional healers for 53.3%. 18.4% sought treatment from both sources. Victims who delayed receiving treatment from a formal facility were more likely to have consulted a traditional healer (OR 8.8995% CI [3.83, 20.64]). Delays in treatment seeking were associated with significantly increased odds of having a severe outcome, including death, paralysis or loss of consciousness (OR 3.47 95% CI [1.56; 7.70]). CONCLUSION: Snakebite incidence and outcomes vary by region in Kenya, and treatment-seeking behaviors are complex. Work needs to be done to better characterize the spatial distribution of snakebite incidence in Kenya and efforts need to be made to ensure that victims have sufficient access to effective treatments to prevent death and serious injury.

長崎大学工学部研究報告 32(59) 119-123 2002年7月The Ariake Sea is a half-closing water area of approximately 1,700km^2 total area, surrounded by four prefectures. It is interpreted that the big projects around that sea has given some impact to the environment. In this study, we analyzed the transparency and the sea surface temperature of the Ariake Sea by using satellite remote sensing, which has advantage of wide and frequent observation. By the existing formula derived from the observation of Ohmura Bay, transparency in the Ariake Sea has gradually increased between the year of 1990 and 2000,although that has fallen in the Isahaya Bay immediately after the bank closing. Sea surface temperature, estimated by the same procedure, has risen by 0.5-0.6℃ in the same term and this change is quite smaller than the range of the water temperature under which red tide is enhanced. Consequently, it does not seem that red tide was induced by the rise of seawater temperature.

長崎大学工学部研究報告 32(58) 135-140 2002年1月In this paper the authors presented some examples of roof or wall planting works in Nagasaki Prefecture and other places including Fukuoka City, and described the result of temperature measurement of vegetation used for roof or wall planting. As a result it was made clear that the temperature of vegetation was relatively low in comparison with those of other materials on roof and bare wall surface. This made us confirm that roof or wall planting may contribute to the reduction of heat radiated from the earth surface.

長崎大学工学部研究報告 31(57) 123-128 2001年7月Aged people are increasing rapidly in these years and the aging society will be a serious problem of Japan. Although various measures which are tender to the aged or disabled persons are adopted, there are still many barriers in our surroundings. It is necessary to develop a barrier-free society and to reduce the problems when the handicapped face a disaster. In this study, the authors investigated the problems which a handicapped person would meet in fire-extinguishing or refuge action in a fire. The experiments were conducted in the Fukuoka Disaster Prevention Center. To evaluate the difficulty in guiding the aged or disabled people, the barrier-free check was also carried out for public facilities in the Tenjin underground center, Fukuoka City. Simulated experience as an aged or disabled person provides us opportunity to notice that there remain lots of barriers in our surroundings.

長崎大学工学部研究報告 31(57) 135-140 2001年7月Japan has eighty-three active volcanoes and is among the most severely affected countries by volcano eruptions in the world. Also in the year 2000,Usu volcano and Miyake Island erupted on March 31 and July 8,respectively and these eruptions influenced largely to the lives of residents and the industrial section. Developing forecasting technologies of eruptions, not fully established by present, will provide us large social benefits. In this study, the possibility of predicting volcanic eruption was investigated using change in vegetation activity before and after the eruption in Usu volcano area by using satellite data. The result shows that vegetation activity near valcano dropped before eruption.

長崎大学工学部研究報告 31(56) 131-136 2001年1月The authors have attended a citizen organization of DansaNax-Nagasaki" in which a variety of activities are carried out in order to form a welfare community. As a part of these activities they could have an opportunity when a barrier-free investigation was carried out at a shopping street in Omura City and at a large-scale shopping center in Sasebo City. It follows that unfortunately they found a lot of barriers in the Omura shopping street as well as in the Sasebo shopping center in spite of it that the shopping center is recognized as a so called "heart-full building.
