In April 2010, Japan Cabinet Office has published the first countermeasure report for severe flood disasters. This report showed various flood-disaster scenarios and factors that widened damages. One of important suggestions was to transmit precious information for long-distance evacuation. So far, local municipalities have made Flood Hazard Map to inform resident risk and evacuation. In this paper, cognition and effectiveness of a flood hazard map in the down ARAKAWA river Tokyo were measured by social questionnaire survey. In conclusion, there were 3 factors to effect validity of a flood hazard map. There were (1) commitment to their neighborhood organization, (2) experience of Kathleen typhoon in 1947 and (3) level of using targeted river. As results, a logical diagram about a flood hazard map perception was drawn and discussed from a view of community-based approach.

Several policy measures related to green tourism have been enforced from 2001 by Ministry of Agriculture and Forestry (MAF). Rural Development Administration(RDA). Ministry of Environment(ME) and Ministry of Government Administration and Home Affairs(MGAHA). These have to be introduced and managed of their own accord and autonomously. Also, the rural community that has been promoting green tourism must be harmonized with its natural environment, namely natural scenery and rural culture, which provide urban residents with amenity and rurality. So green tourism had better be based on environmental-friendly agriculture because it offers safe foods and areas, many creatures to see and play around. To manage green tourism sustainable, it if important for rural and urban residents to come into close relation and to trade in organic products each other. Lastly, the region bounds in green tourism have to be expanded into county(Gun) unit.

New lake dike in Saemanguem area is 125km length and require a great amount of fill materials, but it's difficult to get the amount of materials and develop a quarry because of environment conservation. Therefore, the solution is to use the dredged soil in project area as the fill materials not to develop quarry. However, characteristic of dredged soil as a silty fined sand is very weak at seepage, sliding, erosion of dike due to infiltration of rainfall, wind etc. So, lake dike using dredged soil must be constructed safely against the unstable problem of dredged sand. The objective of research is to make safe lake dike using dereged soil on construction of Saemangeum new lake dike. So, we analyzed the characteristic of dredged soil and suggested a standard section of lake dike.

A survey was performed to provide current information on professional catering companies. Twenty-three catering companies out of thirty-eight(60% recovery) responded the survey for December in 1998. Foodservice establishments managed by 16 small-middle sized catering companies provided an average of 11,200 meals daily, while those managed by major and small-middle sized catering companies were mainly office(72.2%, 57.1%) and school foodservice(15.2%, 26%). The rates of sales of major catering companies and small-middle sized catering companies increased 24%, 30% respectively in 1998. Self-evaluation in catering companies was conducted for sanitary management. Unsatisfactory results from self evaluation were found in three categories, such as, measurement of internal temperature of food materials at reception, ventilation system in the working area, and hand-washing stations with equipment cleaning and sanitizing facilities in front of the working area. Most catering companies expressed a willingness to apply the Hazard Analysis Critical Control Point (HACCP) system from this survey. $\ulcorner$Professional catering business has arisen as an area requiring more consideration and further study for the production of a safe food.$\lrcorner$

COVID-19 has caused extensive human casualties with significant economic impacts around the globe, and has imposed new challenges on health systems worldwide. Over the past decade, SARS, Ebola, and Zika also led to significant concerns among the scientific community. Interestingly, the SARS and Zika epidemics ended before vaccine development; however, the scholarly community and the pharmaceutical companies responded very quickly at that time. Similarly, when the genetic sequence of SARS-CoV-2 was revealed, global vaccine companies and scientists have stepped forward to develop a vaccine, triggering a race toward vaccine development that the whole world is relying on. Similarly, an effective and safe vaccine could play a pivotal role in eradicating COVID-19. However, few important questions regarding SARS-CoV-2 vaccine development are explored in this review.

Arthroscopic shoulder procedures are one of the most common procedures used to restore function through minimally invasive techniques. With the demand for shoulder arthroscopic procedures comes the need for safe, effective, and efficient surgery that maximizes patient outcomes while minimizing complications. Many variables contribute to visualization in shoulder arthroscopy including vascular anatomy, blood pressure control, arthroscopic pump systems, turbulence control, epinephrine, and tranexamic acid. Furthermore, patient positioning can have a dramatic effect on visualization with both the beach chair position and lateral decubitus positioning having various strengths and weaknesses depending on the intended procedure being performed. The purpose of this review is to examine the benefits and complications reported in the literature for improving visualization in shoulder arthroscopy.

Major approaches of Social epidemiology; 1)holistic, ecological approach, 2)population based approach, 3)development and life-course approach, 4)contextual multi-level approach, have stressed the importance of not only social context of health and illness, but also the population based strategy in the health interventions. Ultimately, it provides the conceptual guidelines and methodological tools to lead toward the healthy public policies; integrated efforts to improve condition which people live: secure, safe, adequate, and sustainable livelihoods, lifestyles, and environments, including housing, education, nutrition, information exchange, child care, transportation, and necessary community and personal social and health services.

In recent years, security is essential factor of our safe network community. Therefore, data encryption/ decryption technology is improving more and more. Elliptic Curve Cryptosystem proposed by N. Koblitz and V. Miller independently in 1985, require fewer bits lot the same security, there is a net reduction in cost, size, and time. In this paper, we design high speed underlying field arithmetic processor for elliptic curve cryptosystem. The targeting device is VIRTEX V1000FG680 and verified by Xilinx simulator.

In this study, pilot's read-back errors were reviewed in terms of its cause and consequence while FAA tried to weigh a new initiative in the atc-pilot communication dispute in opposition of a majority of the aviation community by addressing an interpretive rule of 14CFR 91. Especially human factors in ATC communications were outlined with a view to suggest a line of recommendations for a successful accomplishment of safe flight in the busy terminal airspace.

For survival of human beings clean water is an essential commodity whereas contamination in drinking water threatens to mankind. The main cause of water contamination is social and development activities of human being along with increasing population. The community in the study area has acute shortage of drinking water along with about 40 to 60% has no access to safe drinking water. This study indicates drinking water quality of two major sources of coastal belt of Karachi one is supplied by Karachi Water & Sewerage Board (KWSB) as tap water and the other through groundwater. The physicochemical analysis was carried out by following the standard methods for checking the quality of drinking water. The analyzed results showed that the quality of groundwater was unfit as potable water. The most critical situation was observed as high level of contamination followed by high turbidity and increased salinity levels. TDS in surface water were found 12% above and TDS in groundwater was 20% below the National Drinking Water Quality Standards (NDWQS) of Pakistan as well as the permissible WHO drinking water quality guidelines.
