하수 슬러지 기반 인공경량골재를 이용한 콘크리트의 역학적 특성 평가
문주현,양근혁,김종원,심지혜 한국콘크리트학회 2023 콘크리트학회논문집 Vol.35 No.2
이 연구의 목적은 하수 슬러지 기반 인공경량골재를 이용한 콘크리트(LWAC_SW)의 역학적 특성들에 대한 설계기준 대비 안전성을 평가하는 데에 있다. 주요 실험변수는 경량 잔골재 대비 천연모래의 치환율, 물-시멘트비 및 양생온도 조건으로 설정하였다. 실험결과 LWAC_SW의 인장저항성은 동일 기건 밀도에서 팽창점토 및 플라이애시로 제조된 인공경량골재 기반 콘크리트(LWAC_CF)에 비해 다소 낮은 수준을 보였지만, KCI와 fib 2010 설계식에 의한 예측값보다 높았다. 실험결과들의 회귀분석을 통하여 LWAC_SW의 압축강도 발현, 탄성계수, 쪼갬 인장강도 및 파괴계수 평가식을 제안하였다.

Although the national radiological emergency response system has been improved by incorporating lessons from the Fukushima nuclear power plant accident and recent domestic natural disasters, it has not fully incorporated these lessons. In addition, it cannot deal with a variety of aftermath of the radiological disaster. Even for the same disaster, the national emergency response system should comply with multiple domestic laws in our country. Furthermore, there are a few discrepancies between the articles of the domestic laws that the national radiological emergency response system should address. Therefore, this study investigates the characteristics of radiological disasters, examines articles on the domestic laws related to the national radiological emergency response system, and analyses the Japanese government's responses to the Fukushima nuclear power plant accident. Based on the results of the review, suggestions for the improvement of the national radiological emergency response system in terms of response organization and framework have been proposed in this study.

This study aimed to analyze the characteristics of women who used outpatient services for infertility and their healthcare expenditure. Using data from the 2012-2018 Korea Health Panel Study, we constructed an unbalanced panel data of women aged 20-49 with a history of using outpatient services due to the diagnosis of female infertility (N97). Among the 13,124 observations (2,951 persons), 98 observations (59 persons, 0.7%) were diagnosed with infertility, and they were 34.7 years old on average. All were enrolled in the National Health Insurance, with a college degree or higher (83.7%), in high-income households of the 5th quintile (55.1%), and working in a regular or permanent position (36.7%). The average user fees, including covered and uncovered payments, were 1.44 million KRW per a woman and 1.45 million KRW per a couple. It accounts for about 2.3% of the total household income. Based on Andersen's Behavioral Model of Health Service Use, the predisposing factors, when women were over 35 years of age and had no children, the number of outpatient visits, user fees and its household burden were higher than those under the age of 35 and those with children. Among the enabling factors, there were differences in women's job security, husband’s education level, and household income. There was no significant difference in the outpatient visits for infertility according to the need factors, such as chronic disease and obesity status of women. This study showed that outpatient use for infertility care is concentrated on a higher socio-economic status group, and called for policy attention for women in low-income groups who may experience unmet healthcare needs for infertility treatments.

최근 전 세계적인 원자력 수요 급증으로 민감 기술의 확산에 대한 우려가 커지고 있다. 원자력 수요 증가에 대처하면서 핵비확산체제를 강화하기 위해,다수의 ‘핵연료주기 다자화’ 방안이 제안되었다. ‘핵연료주기 다자화’ 방안이 실현될 경우,우리나라에 영향을 미칠 것으로 예상된다. 따라서 본 논문에서는 ‘핵연료주기 다자화’ 움직임에 대해 우리나라의 적절한 대응책 마련에 도움을 주기 위해,12가지 기존의 ‘핵연료주기 다자화 방안’ 을 검토하고,우리나라에 미칠 잠재적 영향을 평가하였다.

Due to a more favorable climate in the recent relationship between U.S. and North Korea, North Korea nuclear issue is expected to enter the new phase of nuclear verification. From now on, our government should make preparation for taking the appropriate steps against the situation developed after the declaration by North Korea. Therefore, this paper is to identify the problems that may be occurred in the process of verifying and dismantling North Korea's nuclear program and to suggest the policy considerations that should be incorporated in establishing the action plan for verifying and dismantling her nuclear program, based on the analysis of experiences to verify and dismantle the WMDs in the former Soviet Union and in Iraq, respectively.
