        • 해체공사 실무자를 위한 기계식 해체대상 RC구조물의 해석기법 제안

          박성식,이범식,박지영,김효진,손창학,Park, Seong-Sik,Lee, Bum-Sik,Park, Ji-Young,Kim, Hyo-Jin,Sohn, Chang-Hak 한국토지주택공사 토지주택연구원 2011 LHI journal of land, housing, and urban affairs Vol.2 No.4

          우리나라의 RC 구조물 기계식 해체공사에서는 적절하지 못한 해체장비의 선정과 탑재가 원인이 되어 해체작업 중 구조부재가 붕괴하는 사고가 발생하기도 한다. 따라서 RC 구조물의 기계식 해체공사를 계획할 때 해체공사 담당자가 대상 구조물에 탑재 가능한 장비의 등급을 보다 편리하게 결정할 수 있는 해석기법이 필요한 실정이다. 이 논문에서는 4층 규모 실 구조물을 대상으로 재하실험과 구조해석을 수행하여, 선행연구에서 도출한 RC 구조물에 탑재 가능한 장비 등급의 적정성을 규명하고, 해체공사 담당자가 구조물의 안전성을 편리하게 평가할 수 있는 해석기법을 제안하였다. 이 연구에서 제안한 해석기법은 RC구조물 기계식 해체공사의 작업 안전성과 적정한 장비 운영을 통한 작업 효율성 향상에 유용하게 활용될 수 있을 것으로 사료된다. In domestic mechanical demolition work against RC building, unsuitable selection and loading of heavy equipment have led to occasional accidents such as collapse of structural members during the work. Therefore, proper analysis technique to easily decide allowable equipment load on the structure is needed at the planning stage of mechanical demolition work. In this paper, performing loading test and elastic analysis against 4-story building at full scale, we confirm appropriateness for allowable load of equipment on RC structures, which was suggested in previous study, and suggest structural analysis method that can evaluate safety of RC building during the mechanical demolition. The suggested method can be effectively utilized to improve work efficiency through safety of mechanical demolition work against RC building and proper management of equipments.

          건조스트레스에 따른 옥상녹화 식물의 생리적 반응

          박성식,최재혁,박봉주,Park, Seong-Sik,Choi, Jaehyuck,Park, Bong-Ju 한국조경학회 2017 韓國造景學會誌 Vol.45 No.2

          본 연구는 저관리 경량형 옥상녹화를 위해 맥문동, 울릉국화, 비비추, 돌나물, 잔디의 내건성을 평가하였다. 옥상녹화 식물의 내건성 평가를 위해 용적수분함량, 엽과 토양의 수분포텐셜, 엽록소 a와 b함량, 엽록소형광, 광합성율, 기공전도도, 증산속도, 항산화물질을 측정하였다. 옥상녹화 식물의 내건성 측정결과, 무관수 일수가 경과하면서 용적수분함량 부족에 따라 식물은 점차 고사하는 경향을 보였다. 울릉국화가 가장 먼저 고사하였으며, 그 다음으로 잔디, 비비추, 맥문동 순이었으며, 돌나물은 고사하지 않았다. 비비추, 맥문동, 돌나물은 3주 이상 생존하여 내건성이 높은 식물로 판단되었다. 엽록소 a와 b는 두 가지 유형이 나타났는데, 초기부터 중기까지 일정한 함량을 유지 후, 급격히 감소하는 I유형에는 비비추, 잔디와 초기에는 낮은 함량을 보이다가 중기 때 급격히 증가 후, 감소하는 II유형에는 울릉국화, 맥문동, 돌나물로 구분되었다. 용적수분함량과 증발산량은 모든 식물 종에서 지속적으로 감소하였으며, 엽록소형광 측정결과, 내건성이 상대적으로 높은 돌나물이 가장 늦게 감소하였고, 잔디와 돌나물은 급격한 감소가 나타난 후 고사하였다. 광합성, 기공전도도, 증산속도는 초기에 높은 활성도가 나타났으나, 용적수분함량의 감소로 인하여 식물체가 기공을 닫아 낮아지는 경향을 보였다. 항산화물질 측정결과, 건조스트레스가 증가하면 항산화물질의 양 또한 증가하나, 높은 스트레스가 유지되면 이러한 화합물이 지속적으로 소비되므로, 항산화물질의 증감은 내건성 평가 지표로 사용할 수 있을 것으로 판단된다. This study evaluated the drought tolerance of Liriope platyphylla F.T.Wang & T.Tang, Dendranthema zawadskii var. lucidum (Nakai) J.H.Park, Hosta longipes (Franch. & Sav.) Matsum., Sedum sarmentosum Bunge and Zoysia japonica Steud. for an extensive green roof. In order to assess drought tolerance of green roof plants, several criteria were measured such as volumetric water content, leaf and soil moisture potential, chlorophyll a and b, chlorophyll fluorescence, photosynthesis, stomatal conductance, transpiration rate and antioxidants. The results of the drought tolerance measurement of green roof plants focused on the gradually withering of plants from lack of volumetric water content. D. zawadskii was the first to show an initial wilting point, followed by Z. japonica, H. longipes and L. platyphylla in order while S. sarmentosum showed no withering. It was concluded that H. longipes, L. platyphylla and S. sarmentosum were highly drought tolerant plants able to survive over three weeks. Furthermore, chlorophyll a and b were divided into two types: Type I, which kept regular content from the beginning to the middle of the period and suddenly declined, like H. longipes and Z. japonica; and Type II, which showed low content at the beginning, sharply increased at the middle stage and decreased, like D. zawadskii, L. platyphylla and S. sarmentosum. Volumetric water content and the amount of evapotranspiration consistently declined in all plant species. The analysis of chlorophyll fluorescence results that S. sarmentosum, which had relatively high drought tolerance, was the last to decline, while Z. japonica and S. sarmentosum withered after rapid reduction. At first, photosynthesis, stomatal conductance and transpiration rate showed high activity, but they lowered as the plant body closed stomata owing to the decrease in volumetric water content. Measuring antioxidants showed that when drought stress increased, the amount of antioxidants grew as well. However, when high moisture stress was maintained, this compound was continuously consumed. Therefore, the variation of antioxidants was considered possible for use as one of the indicators of drought tolerance evaluation.

          박성식,이성복,신상훈,Park, Seong-Sik,Lee, Sung-Bok,Shin, Sang-Hoon 한국토지주택공사 토지주택연구원 2011 LHI journal of land, housing, and urban affairs Vol.2 No.4

          본 연구는 LH의 다가구임대주택 철거 신축사업에 대비하여 노후주택에 대한 해체공사비를 합리적 근거에 의하여 예측하는 것을 목표로 한다. 이를 위하여 소형주택 해체공사 수행 현황과 작업 프로세스를 조사하고 공사비 견적전문가 면담을 통해 해체공사비 산정실태를 파악하였다. 아울러 공공건설공사의 '예정가격 산정기준'과 '건설폐기물 처리비 산정기준', 선행연구 및 문헌을 고찰하였다. 연구 결과의 하나로 표준품셈에 기초한 해체공사 원가계산체계와 내역체계 및 관련 일위대가를 제안하고, 이를 활용하여 지상 2~3층 규모의 다가구임대주택에 대한 해체공사 예정가격을 산출하였다. 산출 결과, 1개 동당 해체공사비는 18,331천원, 바닥면적($m^2$) 기준 104천원으로 예측되었는데, 세부적으로는 직접 철거비가 14,339천원/동, 폐기물 위탁처리비는 3,992천원/동 소요될 것으로 나타났다. 연구 결과는 노후 다가구임대주택 철거 신축사업의 예산수립 단계에서 사업비 추정을 위한 기본 자료로 활용될 뿐 아니라, 연구 제안한 해체공사 원가계산체계 및 내역체계는 공공 건설공사의 발주업무에 유용하게 활용되리라 기대한다. This study is aiming at estimating the demolition cost of deterioration housing by the rational method in order to provide for the demolition and new build project of the rental multi-family housing of LH. We investigated the actual state of demolition construction and work process of small size housing, and analysed an actual condition of estimation for the demolition cost through an advice by the expert of construction cost estimate. Furthermore, the 'estimation standard for the predetermined amount', 'estimation standard for the disposal cost of construction wastes' and precedent studies in public construction work were considered. As one of results in this study, cost accounting system, breakdown system and construction cost for the demolition work based on the standard of estimate were proposed and the predetermined amount of demolition construction for the multi-family housing with 2 or 3 floors could be produced by them. Eventually, It is estimated that the demolition cost per a multi-family housing is about 18,331,000(won) and 104,000(won) per floorage($m^2$). To the details, the result indicated that the direct demolition cost needs about 14,339,000(won) per a multi-family housing and the consignment disposal cost of wastes needs 3,992,000(won) per one. The results of the study will be used as the fundamental data to estimate the project cost in the phase of budget establishment for demolition and new build project of the deteriorated rental multi-family housings, and also cost accounting system of demolition construction and breakdown system are expect to be used effectively at the ordering of public construction work.

          "동무유고(東武遺稿) 약성가(藥性歌)" 에 대한 연구(硏究)

          박성식,park, Seong-Sik 사상체질의학회 2001 사상체질의학회지 Vol.13 No.2

          1. Purpose This paper was written in order to understand the concept of ${\ulcorner}$DongMuYooGo YakSungGa${\lrcorner}$ (東武遣稿 藥性歌) which was descending as the material of Sasang pharmacology. So we are planning to make use of the fundamental material of the study on the Sasang Medications and Prescriptions. 2. Methods Through comparing each clause of ${\ulcorner}$DongMuYooGo YakSungGa${\lrcorner}$ on all the sasang -records, we understood that concept. 3 Result 1) ${\ulcorner}$DongMuYooGo YakSungGa${\lrcorner}$ of a literary work of DongMu(東武) which contain special elucidative-method of herb-nature has 18 type of YakSungGa which explain each 27 herbs for the Taeeumin, Soyangin and Soeumin. The period of authoship is supposed to the time just before ${\ulcorner}$DongyiSuseBowon Gabobon${\lrcorner}$ (東醫壽世保元 甲午本)(1894, DongMu 58 years old) or middle of fifties(53-57 years old). 2) YakSungGa of ${\ulcorner}$DongMuYooGo${\lrcorner}$ which is published by the BoGunsung(保健省) of North Korea is supposed to close to original type. The main meaning of that is the herb-nature which works on the weakst point of each Sasangin. And then the herbs were classfied by the diseases and symptoms possessing Bomyungjiju(保命之主), the herb's efficacy is explained at the each constitution. 3) The meaning of ${\ulcorner}$DongMuYooGo YakSungGa${\lrcorner}$ is exposure of the opinion of DongMu's early stage that proposed herb-nature which is applied to the principle of Jang(臟) of Sasangin, reason and purpose to enact newly created prescriptios by the constitutional diseases and symptoms, and the compositional principle of newly created prescription. 4) The selection of herbs or cogution of herb-nature of DongMu's pharmacological opinion of his early stage was changed by accumulating clinical experience. So all the newly created prescriptios of ${\ulcorner}$DongyiSuseBowon${\lrcorner}$ could not be explained by only the herb and the herd-nature on ${\ulcorner}$DongMuYooGo YakSungGa${\lrcorner}$. Therefore the purpose of DongMu's YaksungGa is not explaining the symptoms in charge of each herb or classifying the herb by constitution, but offering the principle of composition of prescription of Sasang, from the necessary herb which possess and expand Bomyungjiju to nature of herb which is applied to the constitution for treating all the diseases and sypmtoms by the heavy or light and slow or speedy.

          동무(東武) 이제마(李齊馬)와 최문환(崔文煥)의 난(亂)

          박성식,Park, Seong-sik 사상체질의학회 1997 사상체질의학회지 Vol.9 No.2

          연구 목적 : 동무 이제마는 1984 년에는 '한국문화예술선현(韓國文化藝術先賢)' 50인 중의 한 사람으로 지정되고, 1996년에는 12월이 '이제마의 달'로 지정되어 그의 업적을 기념하였으나, 일부 역사가는 그가 1896년 함경도(咸慶道) 의병장(義兵將) 최문환(崔文煥)을 잡아 가둔 인물이라 하여 그의 업적 평가에 문제를 제기하기도 한다. 이에 본 연구는 1896년 함흥에서 일어난 소요를 중심으로 당시의 시대 상황 및 발생 동기와 경과 과정을 규명함으로써 이 사건에 대한 정확한 평가(評價)를 내리고 이를 통해 이제마(李濟馬)의 사상적(思想的) 연원(淵源)을 연구하는데 단서를 찾고자 한다. 연구 방법 : 본 연구는 먼저 조선 후기의 시대적 배경과 을미의병에 대해 살펴 보고 1896년 (병신(丙申)) 함흥에 서 최문환을 중심으로 일어난 사건을 정부측(政府側) 기록, 의병(義兵)(최문환(崔文煥))측(側) 기록, 이제마측(李濟馬側) 기록, 그리고 직접적으로 관련이 없이 나타나는 기타(其他) 사료(史料)들을 중심으로 비교 검토하였다. 연구 결과 및 결론 : 1896년 2월 함흥(咸興)에서 일어난 혼란은 을미사변(乙未事變)과 단발령(斷髮令)으로 폭발한 을미의병운동의(乙未義兵運動)의 일환으로 최문환(崔文煥)이 중심이 되어 단발(斷髮)을 강요하던 관리(官吏)들을 살해한 사건이다. 이 때 이제마(李濟馬)는 최문환을 붙잡아 가두고 난(亂)을 진압하여 훗날 '의병을 탄압했다'는 비난을 받게 된다. 그러나 당시는 수구(守舊)와 개화(開化)가 충돌하는 시기였으며, 이러한 혼란으로 말미암아 있을 수 있는 원산(元山) 일본군(日本軍)의 공격으로부터 주민(住民)의 안전(安全)을 최우선적으로 보호하기 위한 행동이었다. 이와 같은 행동을 근거로 보아 이제마는 유생의병(儒生義兵)들이 주장하던 위정척사(衛正斥邪)의 주자학적(朱子學的) 문화이념(文化理念)이나 복고주의적(復古主義的) 정치이념(政治理念)과는 다른 사상(思想)을 가지고 있었으며, 내면적으로는 새로운 변화를 추구하고 있었음을 알 수 있다. 향후 한국(韓國) 민족운동사적(民族運動史的) 측면(側面)에서 의병장(義兵將) 최문환(崔文煥)에 대한 좀 더 많은 연구(硏究)가 필요할 것으로 생각한다. Purpose : Dong-Mu(東武) Lee Je-Ma(李濟馬) was designated as a member of fifty persons 'The Wise Ancestors of Korean Culture and Art' in 1984 and the december of 1996 was appointed as 'The Month of Lee Je-Ma'. Though his achivements was valued like this, some historian criticized that he suppressed the righteous army. So this study was for clarifing the background, the motive, and the course of 'The Rising of Choi Moon-Hwan' occurred in Hamhung on february in 1896, and for the correct appraisement about this event. And also through this, author tried to make clear the origin of Lee Je-Ma's thought. Method : After studing the background of the end of Chosun dynasty and the righteous army in 1895(乙未義兵). Author made a comparative study through the historical materials of the goverment side, the Choi Moon-Hwan side, and the Lee Je-Ma side about 'The Rising of Choi Moon-Hwan' occurred in Hamhung on februrary in 1896. Results & Conclusion : The event occurred in Hamhung on february in 1896 was a part of rebellion of the righteous army in 1895 which had risen against The startling Occurrence of 1895'(乙未義兵) and 'The Royal Commands To Cut Off People's Hair'(斷髮令). Lee Je-Ma suppressed the Rising and put Choi Moon-Hwan in the prison, and which was criticized that he suppressed the righteous army later day. That time was a conflict period between conservatism and civilization, and the Lee Je-Ma's act was the best way to protect the security of residents from the attack which maybe occurred by Japanese army in Wonsan. Judging from this events, author could find Lee Je-Ma's thought was quite different from righteous army's neo-confucianism and conservatism. In the aspect of the history of 'Korean National Movement', further study about Choi Moon-Hwan, the chief of righteous army will be need.
