          서울시 단독주택지의 독립형 저층공동주택 제안에 관한 연구

          김재철(Kim, Jae-Cheol), 김경연(Kim, Kyoung-Yon), 전병권(Jun, Byung-Kweon) 대한건축학회 2014 대한건축학회논문집 Vol.30 No.1

          As a measures for improving a housing environment, this study suggests a planning of detached low-rise multi-plex houses, which are applicable to part of the reconstruction housing site in Dapsipri, one of the detached public housing sites constructed in 1956. The purpose of this study is to suggest an architectural alternative, which can improve the quality of dwelling while maintaining the residential environment of the detached housing site. The planning of detached low-rise multi-plex houses for the reconstruction housing site in Dapsipri has the following features: 1)This planning ensures the equal quality of sunlight environment by considering the current physical housing density and by arranging four types of unit housing modules which consider the width and direction of streets. 2) This planning uses a rehabilitation redevelopment method for each lot, which has dilapidated buildings. This approach will be able to maintain previous housing lots and road systems where various housing groups have been formed over the years in the reconstruction housing site. 3)This planning provides an easy access to roads by increasing the width of inner streets within unit housing and by considering the geographical condition of each lot. 4)This planning provides community space to ensure connectivity among residents and to revitalize communications among residents. It designs public streets as a community space through an inward common space, which directs toward housing blocks, in addition to the outward common space, which directs toward the roads. This study discovered that the current residential environment of the Dapsipri reconstruction housing site is poor. To improve such a poor living environment, this study suggests a detached low-rise apartment planning, which still maintains the existing housing density and the existing geographical context, by taking a rehabilitation redevelopment approach. The planning suggested in this study will be able to restore physical rationality. However, it will face limitations in improving residents' awareness about redevelopment and in leading to a flexible interpretation of the related laws.

          1985년 4월부터 1989년 9월까지 경부대학교병원 치료방사선과에서 두경부 악성 임파종으로 진단되어 복합화학요법 및 방사선 병용치료를 받은 26명을 대상으로 치료성적을 분석하였다. 완전관해율은 88%, 부분관해율은 12%였고 관해율에 영향을 미치는 예후인자는 없었다. 3년 생존율 및 3년무병 생존율은 각각 62.4% 및 65.2%였다. 생존율이 높았던 군은 편측성 임파절침범(p<0.05), 방사선량 5000cGy 이상(p<0.01), 화학요법 6회 이상(p=0.06)등이었다. 26예 중 8예(부분관해 3예 포함)에서 재발을 했으며 재발 양상은 국소재발 1예, 원격전이 1예, 인접조직에 대발 1예, 국소 재발 및 원격전이 2예 등이었다. From April 1985 to September 1989, 26 patients with stage Ⅰ and Ⅱ non-Hodgkin's lymphoma of unfavorable histology localized in head and neck region were treated with combined modality(combination chemotherapy plus radiotherapy) at the Department of Therapeutic Radiology in Kyungpook National University Hospital. Of the 26 patients, 23 showed complete response and 3 partial response. Between these two groups there were no statistical differences according to the variables. Three-year survival and disease-free survival rate were 62.4% and 65.2%, respectively. Unilateral involvement of neck node (p<0.05), radiation dose over 5000 cGy (p<0.01), and 6 or more cycles chemotherapy (p=0.06) had a favorable effect on 3 yeat survival rate/ There were 8 recurrences including 3 partial responders, 1 local failure, 1 distant failure, 1 contiguous failure, and 2 simultaneous local and distant failure. It could be suggested that combined modality treatment might be necessary for treatment of stage Ⅰand Ⅱ Non-Hodgkin's lymphoma of unfavorable histology.

          김동호(Kim, Dong-Ho), 김상현(Kim, Sang-Hyun), 김성남(Kim, Sung-Nam), 김재철(Kim, Jae-Cheol) 한국체육과학회 2019 한국체육과학회지 Vol.28 No.4

          The purpose of this study was to confirm the effect of core stability exercise, dong-bang therapy, and combined treatment on reducing pain, pelvic correction and stress hormone concentration in patients suffering from sciatic neuralgia due to pelvic displacement. Middle aged(40~50age) suffering from sciatic neuralgia over 6 months were operated with core stability exercise, dong-bang therapy, and combined treatment 3 times a week for 12 weeks. VAS and X-ray was performed to collect pain scales and pelvic displacement data and cortisol and epinephrine concentration in blood were tested. 1. pain scale rate was reduced in all groups. especially, dong-bang therapy group and combined treatment group showed more directive pain reduce. 2. pelvic displacement improvement was not significant in core stability exercise group, and it was significant in dong-bang therapy group and combined treatment group. no significant difference was shown between dong-bang therapy group and combined treatment group. however, combined treatment group showed higher correction effect. 3. concentration of stress hormone was significantly increased in all groups after the first operation. after 12 weeks concentration level was reduced to same level before treatment. Dong-bang therapy and combined treatment improve pelvic displacement, and are effective treatments on reducing sciatic neuralgia due to pelvic displacement. combined treatment of dong-bang treatment and core stability exercise is considered an effective program of correction for pelvic displacement and maintenance.

          수용액 매체로부터 코디어라이트 졸의 제조 및 코디어라이트 세라믹스의 소결거동

          김재원,김현철,김두현,서성문,조창용,최승주,김재철,Kim,,Jae-Won,Kim,,Hyeon-Cheol,Kim,,Du-Hyeon,Seo,,Seong-Mun,Jo,,Chang-Yong,Choe,,Seung-Ju,Kim,,Jae-Cheol 한국재료학회 2000 한국재료학회지 Vol.10 No.3

          소결 촉진제 첨가없이 치밀한 코디어라이트 세라믹스를 얻기 위해 Mg-Al-Si계의 열적거동을 검토하였다. 수용액 매체에서 코디어라이트 현탁액의 분산안정성을 ESA를 이용하여 조사하였으며, 코디어라이트 졸의 응집 방지와 분산성을 부여하기 위해 2N $HNO_3$와 2N $NH_4OH$ 용액으로 pH 1.03과 pH 8.30로 조절하였다. pH 8.30인 코디어라이트 졸을 $150^{\circ}C$에서 12시간 건조한 시료에서 magnesium-aluminum-silicate 복합 겔이 존재하였다. 평형상태의 코디어라이트 겔의 결정화는 $1300^{\circ}C$ 이상의 소결 온도에서 존재하였으며, $1300^{\circ}C$ 이하의 조건에서는 ${\mu}-cordierite(Mg_2Al_4Si_5O_18)$, spine($MgAl_2O_4$) 및 mullite($Al_6Si_2O_{13}$)와 같은 다양한 준안정상이 복합적으로 혼재하였다. pH 1.03과 pH 8.30로 조절된 현탁액에서 코디어라이트 겔의 핵반응은 유사하게 일어났으나, 치말화거동은 졸의 pH에 상당한 차이를 보였다. pH 1.03인 졸 보다 pH 8.30인 졸의 치밀화가 더욱 진전되었다. In order to fabricate dense cordierite ceramics without sintering aid, thermal behavior of Mg-Al-Si compounds during sintering was investigated. The dispersibility of cordierite suspension in aqueous media was measured by ESA(electrokinetic sonic amplitude). To prevent aggregation and insufficient dispersion of the cordierite sol, the pH of the suspension was controlled to 1.03 and 8.30 by adding $2N\;HNO_3$ and $2N\;NH_4OH$, respectively. Magnesium-aluminum-silicate complex gel coexisted in the specimen which has been gelled at $150^{\circ}C$ fir 12 hours, however several metastable phase such as ${\mu}-cordierite(Mg_2Al_4Si_5O_{18}),\;spine(MgAl_2O_4)\;and\;mullite(Al_6Si_2O_{13})$ existed below $1300^{\circ}C$ Nucleation rates of the two suspension were similar, but densification of the gel was sensitive to the pH of the sol. Densification of the sol with the pH of 8.3 was more pronounced than that of the sol with pH of 1.63.

          개인용 휴대 단말기를 이용한 절토사면 관리시스템 개발

          김재철(Kim Jae Cheol), 박재국(Park Jae Kook), 양인태(Yang In Tae) 대한공간정보학회 2007 대한공간정보학회지 Vol.15 No.4

          자연재해의 규모는 해를 거듭할수록 증대되고 있으며, 국가적으로 피해 복구를 위한 막대한 예산이 지출되고 있다. 이러한 피해의 근본적인 해결을 위해서는 사후대책에서 예방위주의 정책으로 패러다임의 전환이 필요할 때이다. 예방위주의 정책을 실천하기 위해서는 IT기술, 첨단정보수집기술, 운영기술 등 첨단기술의 통합을 유도하여 광범위한 자연재해를 예측하고 평가할 수 있도록 해야 할 것이다. 그러나 현재 우리나라는 IT 강국임에도 불구하고 현장정 보수집에 있어 여전히 종이양식을 이용하는 경우가 대부분이다. 특히 과거 산사태 발생지와 사면정보가 종이형태로 유지되어 정보의 공유가 어렵고, 자료가 유실되거나 내용을 식별하기가 매우 힘들다. 따라서 본 연구에서는 정보수집과 시스템과의 호환성, 정보의 관리차원에서 절토사면을 대상으로 PDA를 이용하여 정보수집 및 관리시스템을 개발하고자 하였다. 그 결과 실시간으로 현장 정보를 다양한 형태(위치, 사진, 텍스트)로 수집이 가능하였으며, 현장에서 SMR법을 이용하여 암반사면의 안정성 여부를 개략적으로 판단할 수 있었다. The scale of a natural disaster grows bigger and bigger every year. The government spends much of its budget on recovering the resulting damage on a national scale. It is important to shift the paradigm from taking measures after a disaster to that of taking preventive actions before a disaster in order to bring a fundamental resolution to such problems. In taking preventive actions and policies, it is necessary to integrate various kinds of advanced technologies including IT, high-tech information gathering technology and operational technology, and to predict and evaluate natural disasters on a comprehensive level. Although Korea is a country with a strong IT sector, most information gathering is still performed in paper. In particular, information about the areas of previous landslide occurrences and slopes remains on paper, which makes it difficult to share the information and to discern the contents, and also raises the possibility of missing documents. Thus this study set out to develop an information gathering and management system for cutting slopes using PDA from the perspective of information gathering, system compatibility, and information management. As a result, field information may be gathered in a variety of forms (location, photos, and texts) real-time. A rough judgment was also made of the stability of rock slopes using the SMR method on the field.
