International Journal of Advanced Research, 12(01) 586-593, Jan 31, 2024 Peer-reviewedLead authorThis 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, Nov 30, 2023 Peer-reviewedLead authorThe 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, Oct 20, 2023 Peer-reviewedFemale 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, Apr 29, 2022 Peer-reviewedINTRODUCTION: 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.

西南学院大学人間科学論集, 11(1) 101-118, Aug, 2015ハワイ島は、西北西~東南東方向に配列する延長2,400km に及ぶハワイ列島の島嶼群の南東端に位置し、面積10,451k㎡の火山島である(Macdonald, G. A., Abbott, A. T. and Peterson, F. L., 1983)。ハワイ列島はホットスポット上に形成された火山島群から成り、ホットスポットの上に位置する太平洋プレートの等速的な移動の結果、点々と火山が連らなる島列を形成したものと考えられている。Dalrymple, G. B. ほか(1973)は、太平洋プレートの移動速度と火山岩の年代との関係を検討した結果、太平洋プレートの西北西方向のほぼ直線的かつ等速的な移動を、マントル深部に位置するホットスポット仮説で説明できると考えた。現在はハワイ島周辺で溶岩流出が活発であり、この事実は、一般的には、ハワイ島下方のマントル深部に位置すると推定されるHawaiian Hot Spot の存在で説明されることが多い。Dalrymple らが現在のHawaiian Hot Spot の真上に形成されている火山としたハワイ島のキラウェア火山は、中心火口であるキラウェアカルデラと、その東方に延びるイーストリフトゾーン(East Rift Zone)で最近も度々噴火を繰り返しており、溶岩流の噴出年代が特定されている数時期の溶岩流を噴出しているほか、現在も継続的に溶岩を流出する活動を継続中である。ここでは、溶岩流地帯の土地条件の変化過程の自然的特徴について解析する目的で、西南学院大学研究助成制度「湿潤熱帯地域における火山等自然災害後の土地条件変化に関する研究」の助成を受けて、2015年3月1日~6日に実施したハワイ島イーストリフトゾーンの現地調査について報告し、特に溶岩流地帯に植生が侵入するプロセスについて、現地調査で明らかになった点を中心に報告する。なお、主たる調査地域は、ハワイ島東南部プナ(Puna)地区のパホア(Pahoa)からカイム(Kaimu)(Kalapana 付近)までの州道130号線、カイムからカポホ(Kapoho)までの137号線、カポホ(Kapoho)(Kumukahi 岬付近)からパホアまでの132号線の沿道を中心とした地域周辺である。

7(7) 32-39, Mar 31, 2015The debris flow disaster occurred at Hiroshima city at August 20, 2014, where 74 lives were lost. Because Hiroshima city has lots of sediment disasters from before, their sense of impending crisis has been strong. Actually Japanese government has enacted "Sediment Disasters Prevention Act" learned from the past disaster at Hiroshima city. We have conducted some field surveys, and have grasped from various angels a character of the debris flow disaster occurred at Hiroshima city. To summarise, we have investigated about the future task for regional disaster prevention.

応用地質, 55(6) 307-316, Feb 10, 2015 We researched geomorphic quantities on micro landforms at our study area damaged by overland flood due to the typhoon no.0514 in the Miyazaki Plain. Many micro landforms can be classified in the downstream area of Ooyodo River and Honjo River. The study area adjacent to both rivers was classified into the landforms such as dike, slightly elevated area, lowland and river bed from the interpretation of shade maps made by 5mDEM. The geomorphic quantities of the landforms are average height and relative height to water level calculated by using 5mDEM. The characteristics of the longitudinal profiles on both geomorphic quantities were discussed.<br> In the profiles, some sections become convex curve caused by aggradations in elevation of micro landforms. The form of convex curves in the profiles on relative height is clearer than that in the profiles on average height. In the profiles on relative height, we can identify large convex curves with approximately 5 km wavelength and small ones with approximately 1 km wavelength. The areas with the maximum value in the large convex curves are close to the river mouth to the main river and the sea, the flection of the rivers, and the bottleneck section. Such areas in the small convex curves are close to the confluence of tributaries. Such areas of the landforms outside of the dike are located downstream those of the landforms inside of the dike. At the areas, it is considered that water velocity decreases, sediment accumulates, and flood level is easy to go up. In the inundated area, the relative height of landforms increases outside of the dike and it decreases inside of the dike. In the non-inundated area, the height of them decreases outside of the dike and it increases inside of the dike. Therefore, the relative height difference between lowland and river bed from the each profiles, we can distinguish the sections where are easy to be inundated by overland flood and where are hard to be inundated.<br> Consequently, in this study, we clarified that it is easy for us to recognize the vulnerable area for inundation from the analysis of geomorphic quantities on micro landforms.
