본 연구는 통일 후 한반도의 새로운 수도입지를 풍수적 측면에서 제언하기 위한 것이다. 사례지로서는 고려와 조선시대 천도후보지로 거론된 지역 중, 남북 중간에 위치하여 통일의 상징성이 있는 지역, 비교적 원형이 유지되어 개발부담이 적은 지역을 대상으로 하였다. 그 결과 백악 지역과 도라산 지역 2곳을 선정하여 각각 풍수적 판단을 통해 통일 수도 후보지를 제안하였다. 비교 결과 지리적 여건은 상호 비슷하였다. 즉 임진강을 통한 해상운송과 용수확보가 용이하였고, 철도와 도로 개설이 용이한 점이 있었다. 그러나 풍수적인 판단에 있어서는 백악 지역은 고려 시대 실제 천도를 위한 기초공사가 시작된 곳으로서, 도라산 지역에 비해 풍수의 논리체계인 용, 혈, 사, 수, 향 등에 있어 우위에 있음이 나타났다. 따라서 두 지역만으로 판단했을 때, 백악지역이 면적이나 풍수판단 등에 있어서 도라산 지역보다는 천도 후보지로 적합한 것으로 나타났다. This research is to propose the new capital site for Korea after reunification on account of Feng Shui. Among the nominated capital regions during Korea Dynasty or Chosun Dynasty, the Baekak and the Dorasan regions are selected because they are located in the middle of North and South Korea and that they have less economic burden for development with their pristine conditions. Even though both Baekak and Dorasan regions are adjacent to Imjin River for water supply and have advantage in making roads for transportation, from Feng Shui’s point of view, the Baekak region has superiority over the Dorasan region in terms of Yong, Hyol, Sa, Su, Hyang. Therefore, it is concluded that the Baekak region is more suitable for the future capital site of the reunified Korea.

경화 지연제 혼입 콘크리트의 부착전단강도 및 부식내구성 평가

손진수(Jin-Su Son),이진영(Jin-Young Lee) 한국방재학회 2023 한국방재학회논문집 Vol.23 No.4

본 연구에서는 경화지연제를 혼입한 콘크리트의 부착전단강도 및 부식내구성을 평가하였다. 경화지연제 혼입 콘크리트의 성능을 평가하기 위해 경사전단시험, 직접전단시험, 가속화부식시험을 수행하였다. 시험의 변수로는 경화지연제 혼입율(0, 1%), 콘크리트 타설면 처리방법(무처리, 치핑, 브러싱), 상층부 콘크리트 지연 타설 시간(8, 16, 24 h)이 고려되었으며 가속화 부식 시험의 경우 콘크리트 피복 두께 변수(20, 30, 45 mm)가 추가로 고려되었다. 시험의 결과로 경화지연제를 혼입한 시험체의 부착전단강도가 일반 콘크리트 시험체에 비해 더 높게 나타났으며 지연 타설 시간이 증가함에 따라 부착전단강도가 감소하는경향이 나타났다. 또한 경화지연제의 혼입을 통해 철근콘크리트의 부식내구성 향상을 확인하였으며 이러한 결과를 통해 경화지연제의 혼입이 지연 타설로인해 발생할 수 있는 타설 경계면의 부착강도와 내구성 저하 문제를 해결할 수 있는 적절한방안이 될 수 있다고 판단된다. In this study, the bond shear strength and corrosion resistance of concrete with setting retarders were evaluated. For this, slant shear, bi-surface, and accelerated corrosion tests were conducted. The variables considered included the proportion of the setting retarder (0 and 1%), surface treatments of concrete (as-cast, chipping, and brushing), curing hours (8, 16, and 24 h), and concrete cover depths (20, 30, and 45 mm). Consequently, the bond shear strength of concrete with the retarder showed a higher value than that of normal concrete. Moreover, an increase in curing hours resulted in a higher value of the bond shear strength. Furthermore, the addition of a retarder in concrete increased corrosion resistance. Based on the test results, the addition of a setting retarder is believed to be a suitable solution to address the bond shear strength and durability issues that may arise at the interface of delayed concrete placement.

This study`s aim is to isolate and characterize plant growth promoting Enterobacter species for the biological control of gray leaf spot in pepper. Screening was carried out from the rhizosphere of Agropyron tsukushiensi var. transiens (Hack.) Ohwi in Dok-do. Rhizobacterial isolates were partially identified by 16S rDNA sequencing and Enterobacter species were tested for plant growth promoting capabilities and the induction of systemic resistance in pepper against gray leaf spot caused by Stemphylium solani. Isolates were tested for production of indole-acetic acid and siderophore, and for phosphate solubilization. The application of isolates was effective in controlling gray leaf spot in pepper with E. asburiae (KNUC5007) and E. cancerogenes (KNUC5008 and KNUC5010) having the highest efficacy in reducing gray leaf spot severity. This is the first report of the biological control of gray leaf spot in pepper using rhizobacteria and it is hoped that this study will increase the utilization of Enterobacter species as plant growth promoters and biocontrol agents.

대한민국의 농업용 저수지는 대부분 축조된 지 50년 이상 되었다. 농업용 저수지는 예상치 못한 자연재해로 인해 붕괴되는 것을 막기위해 유지보수와 보강이 필요하다. 본 연구에서는 태양광 패널이 적용된 농업용 저수지 사면의 안정성과 경제성 평가를 수행하였다. 태양광 패널이 설치된 사면의 안정성은 Slope/w 프로그램을 사용하여 평가되었고 보강 방법과 태양광발전 시스템의 부하를 고려하였다. 또한 RETScreen 프로그램을 사용하여 태양광 발전 시스템의 경제성 분석을 수행하였다. 경제성 분석에는 태양광 모듈의 단위 비용, 태양광 패널의 수명, 그리고 대상 저수지의 기후 환경이 고려되었다. 결과적으로, 태양광 시스템과 보강 방법의 적용으로 저수지 사면의 안정성이 향상되었다. 게다가 전기 생산 및 온실 가스 감축과 같은 경제적 이점을 기대할 수 있음을 이론적으로 확인하였다. In Korea, the majority of agricultural reservoirs have been in use for over 50 years. Hence, there is an urgent need for maintenance and reinforcement to safeguard against potential collapses caused by unforeseen natural disasters. This study assessed the stability and economic viability of applying solar panels to these agricultural reservoir embankments. The Slope/w program was used to analyze the stability of embankments fitted with solar panels, considering reinforcement techniques and the load from the photovoltaic (PV) system. The economic feasibility of the PV system was determined using the RETScreen program, factoring in the unit cost of solar modules, lifespan of solar panels, and specific climatic conditions of the target reservoir. The findings indicate that the PV system and reinforcement techniques enhanced the stability of the reservoir embankments. Furthermore, economic benefits, such as production of electricity and reduction of greenhouse gas, can be expected.
