Background: The coronavirus disease 2019 (COVID-19) pandemic is a major public health problem of international concern. It is important to estimate its impact of COVID-19 for health policy decision-making. We estimated the years of life lost (YLLs) due to COVID-19 in high-incidence countries. Methods: We collected the YLLs due to COVID-19 in 30 high-incidence countries as of April 13, 2020 and followed up as of July 14, 2020. Incidence and mortality were collected using each country's formal reports, articles, and other electronic sources. The life expectancy of Japanese females by age and the UN population data were used to calculate YLLs in total and per 100,000. Results: As of April 22, 2020, there were 1,699,574 YLLs due to COVID-19 in 30 high-incidence countries. On July 14, 2020, this increased to 4,072,325. Both on April 22 and July 14, the total YLLs due to COVID-19 was highest in the USA (April 22, 534,481 YLLs; July 14, 1,199,510 YLLs), and the YLLs per 100,000 population was highest in Belgium (April 22, 868.12 YLLs/100,000; July 14, 1,593.72 YLLs/100,000). YLLs due to COVID-19 were higher among males than among females and higher in those aged ≥ 60 years than in younger individuals. Belgium had the highest proportion of YLLs attributable to COVID-19 as a proportion of the total YLLs and the highest disability-adjusted life years per 100,000 population. Conclusion: This study estimated YLLs due to COVID-19 in 30 countries. COVID-19 is a high burden in the USA and Belgium, among males and the elderly. The YLLs are very closely related with the incidence as well as the mortality. This highlights the importance of the early detection of incident case that minimizes severe acute respiratory syndrome coronavirus-2 fatality.

The disability adjusted life year (DALY), a single indicator of the burden of disease, is widely used to measure the burden of diseases, injuries, and risk factors. In this study, we review the relative sizes of the burden of disease worldwide and the characteristics of the burden of disease of the Korean population. Future research directions for study of the burden of disease in Korea are also suggested. In the Korean population, diabetes mellitus was the leading cause of the burden of disease (970 DALYs per 100,000 population) in 2002, followed by cerebrovascular disease (937 DALYs per 100,000 population) and asthma (709 DALYs per 100,000 population),which differed with the leading causes of the burden of disease globally: unipolar depressive disorder, ischemic heart disease, and cerebrovascular disease. In 2007, cirrhosis of the liver in males and cerebrovascular disease in females became the leading causes of the burden of disease of the Korean population with the epidemiologic transition. Despite the methodological difference with global burden of disease study, these findings represent the characteristics of the burden of disease in Korea. Though many studies have been conducted to measure the burden of disease in Korea, there is a need to go beyond these to combine policymaking for resource allocation, such as cost effectiveness analysis, with burden of disease studies.

The municipal corporations that consolidated urban with country in 1995, are planning a new building or extention work of cityhall for insufitcient office space or office to he separated. But they' find it hard to calculate scale of city office space because standards of office area the Department of the Interior proposed are don't reflect now changes New changes are made a general classification two parts First in the changes of administrative plans, MC is to adapt at cityhall design plan and the number of user of cityhall office space is changed The second is social changes of An information engineering of a high order, an office automation and need for amenity of worth surrounding. Because this study proposes new standards of city office and number of user, calculate scale to be fit for consolidated cities in Gyeong-nam, make a comparision between scale of this study and practical plan

Solid/Liquid(S/L) separation is crucial for biological treatment of animal wastewater. Liquid portion from S/L separation has less BOD-load and proper post-strip treatment can be obtained. Screen or declined sieve was normally used to separate the solid parts. For better separating efficiency a vibration and a cylindrical separator were constructed and tested. The results are summarized as follows; Solids removal efficiency and moisture content of separated solid were 15~26% and 85~88%, respectively for the vibration separator. for the cylindrical separator, solid removal efficiency and moisture content of solid were 16~39% and 86~89%, respectively. The greatest amount of drymatter was obtained when operating vibration separator with 10$^{\circ}$ inclination and 100% vibrating power. For the cylindrical separator maximum efficiency was obtained with 40 rpm and 19$^{\circ}$ inclination. The vibration and the cylindrical separator have shown 21% and 26% in BOD removal, respectively. These two types of separator were proved to be applicable methods for animal wastewater separation. 축사뇨오수의 전처리단계로 고액 분리기를 제작하여 분리효율에 관한 시험을 수행한 결과는 다음과 같다. 진동체 고액분리기는 최저 15%에서 최고 26%까지 분리율을 나타내었으며, 분리고형물의 수분함량은 85~88% 사이였다. 회전원통형 고액분리기도 최저 16%에서 최고 39%까지 분리율을 나타내었으며, 고형물의 수분함량은 86~89% 사이였다. 최대의 분리고형물량은 진동체 고액분리기의 경우에 체의 경사도 $10^{\circ}$와 진동모터 가진력 100%, 회전원통형 고액분리기에서는 회전속도 40rpm과 경사각 19$^{\circ}$에서 얻을 수 있었다. BOD 제거율은 회전원통형 고액분리기가 26%로 진동체 고액분리기의 21% 보다 다소 높았다. 관리측면에서는 회전원통형 고액분리기는 주기적으로 세척을 하여 주어야 한다.

An efficient Treatment of animal wastewater is one of the hot issues for preventing the environmental pollution. It should be established the design parameter in order to purify the animal wastewater. A test is carried on in the pilot plant as a simplified activated sludge process. A vibration sieve separator is deviced to keep the pollution load constant by means of separation of solid matter. The BOD removal efficiency of the vibration sieve showed over 50%. As the test results, the BOD contents of the influent was in average of 3,000 mg/I and that of the effluent 85 mg/I. So, the BOD removal rate showed 97% in average. The SS-contents in the primary chamber was about 3,300 mg/I and that of effluent 92 mg/I. The SS removal efficiency showed 97%. The removal rate of total nitrogen and phosphore were in average of 82% respectively. Carrying out in winter season, it showed relatively good results; The design parameter approved in this test can be applied to the full-time farmers.

항온층 지열을 이용하는 지열교환기를 개발하여 겨울철의 난방효과와 여름철과 환절기에 있어서 온습도변화를 분석하였다. 또한 지열교환기가 매설된 토양의 종류는 미사질토로 나타났다. 시험한 결과를 요약하면 다음과 같다. 1. 디지탈풍속계를 사용하여 2월 중 하루동안의 온습도를 측정해 본 결과 입기의 온도가 -7.3$^{\circ}C$에서 6.4$^{\circ}C$의 변화를 보일 때 배기의 온도는 1.2~7.3$^{\circ}C$로 영상의 기온을 나타내었으며, 최대의 온도차 $\Delta$t는 8.5$^{\circ}C$이었다. 난방성능은 최대 3.25Wh/㎥이었으며, 평균 1.7Wh/㎥이었다. 2. 3월과 4월의 온도변화를 측정해 본 결과 땅속 2.5m의 온도와 지하배관내의 공기온도가 모두 10~l2$^{\circ}C$의 일정한 온도범위를 보여 외기의 급격한 온도와는 상관없이 변화폭이 적은 온도의 공기를 축사내로 공급할 수 있었다. 3. 7월 1일부터 5일까지의 온도변화 자료를 분석해 본 결과 지하 2.5m의 온도가 18~2$0^{\circ}C$의 일정한 범위를 보여 지난 3, 4월과 비교하여 지온이 약 8$^{\circ}C$ 정도 상승하였다. 4. 9월 중 일교차가 가장 심했던 9월 19일에서 22일 사이에 입기구와 배기구에서 순간온도변화를 측정한 결과 입기구에서 온도변화는 9~28$^{\circ}C$로 약 19$^{\circ}C$의 온도차를 보였으나 배기구에서의 온도변화는 15~$25^{\circ}C$의 범위를 보여 입기구의 온도변화에 비해 약 9$^{\circ}C$ 정도의 온도차로 완화할 수 있었다. 이상의 시험결과에서 나타난 바와 같이 지열교환기는 축사의 난방 보조열원으로서 양호한 열효율을 나타내어 우리나라 축사시설에 적용가능성을 제시하였다. 본 지열교환기 시스템은 지열을 이용하는 환경보전형 에너지 시스템으로서 시설하기 간편하고 경제적이며 반영구적인 냉난방 및 환기시스템이다. 따라서, 우리나라 축산시설에 실용화될 경우에 우수한 대체에너지원으로 에너지 절감효과에도 크게 기여하리라고 전망된다. To use the earth heat for the pig housing, an underground heat exchanger has constructed in depth of 2.5m and 20m length. The temperature of the outlet air was max. 8 kelvin higher than that of inlet air in winter season. In spite of the -7$^{\circ}C$ outside temperature, it could keep the air temperature from the earth tube above zero degree. The heating performance was maximum in value of 3.25Wh/㎥ and average of 1.75Wh/㎥ by the airflow volume of 340㎥/h. The slope of relative humidity from outlet air has shown gentler than that of inlet air. By using the underground heat exchanger, it would be possible to prepare an relatively uniform relative humidity in the swine stalls. The temperatures on the earth, where PVC pipes are buried, have shown 10~12$^{\circ}C$ on March. This can reduce the difference between day and night temperature during this season by using the underground heat exchanger.
