하승범 국제문화기술진흥원 2024 The Journal of the Convergence on Culture Technolo Vol.10 No.1

BIM was activated by applying it necessarily to the government ordered construction of more than a certain amount of money in architecture and construction field of Korea before and after 2010. An architectural education using BIM at college in Korea has been doing in accordance with this trend but is not too different from the existing interior design studio. Also, a new design curriculum based on BIM that provides a digital design concept and a digital working environment is increasingly being demanded in modern society. A digital-based design process is required not only in the field of architecture but also in the field of interior. Therefore, this study suggests the prototype of the interior design studio based on the field practice can apply BIM design, not the unfamiliar interior design studio pursued in the field practice to understand easily the environment of interior design process BIM is essentially seeking.

비정형 설계 프로젝트의 BIM설계 프로세스에 대한 연구

하승범 국제문화기술진흥원 2020 The Journal of the Convergence on Culture Technolo Vol.6 No.2

21세기에 접어들어 정형화된 건축물에서 비정형 건축물이 눈에 띄게 건설되기 시작하였다. 이제 ‘기념비적인 건축물은 비정형 건축물이다.’라는 정의가 성립되기에 이르렀다. 전 세계적으로 비정형 건축물은 도시의 랜드마크가 되었고 비정형 건축물이 건물의 가치를 상승시키는 하나의 요소로 자리 매김한 현재, 보다 효율적인 방법으로 설계할 수 있는 프로세스에 대한 고찰이 요구되었다. 그래서 국내 비정형 건축물의 대표인 ‘Zaha Hadid’의 ‘동대문 디자인 플라자’ (DDP)의 설계프로세스를 실례로 설계프로세스를 고찰함으로써 컨셉 단계의 설계와 실질적 설계단계에서의 BIM(Building Information Modeling) 설계의 상관관계를 고찰함으로써 향후 지속적인 비정형 설계프로세스의 접근방법을 모색하고자 이 논문을 작성하였다. Since the 21st century a free-form building has been noticeably constructed. Now the definition “the monumental architecture is a free-form one.” has come to be established. As a free-form building became a landmark of the city and a factor rising a value of the building all around the world, it is currently required to consider a more efficient design process. Therefore this research aims to learn approaches of the lasting free-form design process by considering the design process of Dongdaemun Design Plaza(DDP) designed by ‘Zaha Hadid’ that is a typical free-form building of Korea and the correlation between the design in the conceptual stage and the BIM(Building Information Modeling) design in practical stage.

압력요속검사로 정의한 여성 방광출구폐색을 진단하는 인자에 대한 연구

하승범,김성수,이승태,민경은,홍성규,변석수,이상은,정성진 대한비뇨의학회 2009 Investigative and Clinical Urology Vol.50 No.9

Purpose: We investigated pre-urodynamic study parameters of bladder outlet obstruction (BOO) defined by pressure-flow study (PFS) in female patients without anatomical obstruction. Materials and Methods: The cohort of this study consisted of 320 women who did not have anatomical BOO in whom urodynamic study was conducted for lower urinary tract symptoms (LUTS). BOO was defined when the PFS maximal flow rate (Qmax) was ≤12 ml/sec and Pdet Qmax was ≥25 cmH2O. The main outcomes were the incidence of BOO and its predictive factors in our cohort. Results: Of the total patients, 39 (12.2%) were diagnosed with BOO in the PFS. Free Qmax and maximal voided volume (MVV) were significant predictors of BOO (p<0.001, p=0.011, respectively) in the multivariate logistic regression. When free Qmax was set to ≤15 ml/sec, its sensitivity and specificity predicting BOO were 82% and 72%, respectively; when MVV was set to ≤350 ml, its values were 71% and 46%, respectively. However, the positive predictive values (PPVs) of free Qmax and MVV were low (34.4% and 28.2%, respectively), whereas the negative predictive values (NPVs) of these parameters were relatively high (96.5% and 91.2%, respectively). Conclusions: Factors predicting BOO defined by PFS in female patients complaining LUTS without anatomical obstruction were free Qmax and MVV. The PPV of these factors was low, and the NPV was high. Therefore, if free Qmax is >15 ml/sec or MVV is >350 ml, PFS may be not essential. On the contrary, if free Qmax and MVV are below these levels, PFS may be indicated to evaluate the presence of BOO.

하승범,박용현,이은혜,구자현,김현회,곽철 대한비뇨의학회 2011 Investigative and Clinical Urology Vol.52 No.5

Purpose: We sought to maximize the antitumor effect of an anticancer vaccine based on genetically modified endothelial cells by combining it with the platelet-derived growth factor receptor inhibitor imatinib. Materials and Methods: Human umbilical vein endothelial cells (HUVECs) were infected with 10 MOI of Ad-CMV-mGMCSF to make anticancer vaccines. One million mouse bladder cancer cells (MBT-2) were subcutaneously inoculated in C3H mice. The experimental groups included the following: Group 1 (phosphate-buffered saline), Group 2 (anticancer vaccine and GM-CSF), Group 3 (imatinib), and Group 4 (anticancer vaccine, GM-CSF, and imatinib). Tumor growth and body weight were measured weekly. At 4 weeks, the tumors were immunostained with anti-CD31, and microvessel density (MVD) was measured. To evaluate the immunological mechanism of each treatment, flow cytometry analysis of activated CD4 and CD8 cells was performed. Results: At 4 weeks, the mean body weight of each group, excluding the extracted tumor weight, was not significantly different. Since week 3, the mean tumor volume in Group 4 was the smallest among the treatment groups (p<0.05), and a synergistic suppressive effect on tumor volume was observed in Group 4. The MVD in Group 4 was the most suppressed among the treatment groups (p<0.05), and a synergistic anti-angiogenic effect was observed. Flow cytometry analysis revealed that activated CD4+ and CD8+ cells increased in Group 2 and decreased in Group 3 compared with the other groups. Conclusions: The combination of genetically modified endothelial cell vaccines and imatinib showed a synergistic antiangiogenic effect in bladder cancer.

농촌 자활사업의 방향성: 참여자들의 자활사업에 대한 인식유형

하승범,신원식 한국사회복지정책학회 2019 사회복지정책 Vol.46 No.3

이 연구의 목적은 농촌지역 참여자들의 자활사업에 대한 주관적 인식유형을 파악하고, 이를 토대로 농촌지역 자활사업의 성과향상 방안을 제시하는 것이다. 자활사업과 관련하여 엄선된 31개의 진술문을 가지고, 농촌지역 자활사업 참여자 25명을 대상으로 Q 분류를 하게 하였으며, Q 요인분석 결과 인식유형은 네 가지로 나타났다. 첫째, ‘적응-현실만족형’은 동료들과의 협의가 매우 중요하며, 자활사업에의 참여가 현재의 어려운 상황을 극복할 수 있지만, 앞으로 나아질 것을 기대하기는 어렵다고 인식한다. 둘째, ‘불만족-제도개선형’은 참여자별 능력에 따른 일자리가 중요하며, 시장진입이 가능한 차별화된 자활 프로그램이 필요하다고 생각한다. 셋째, ‘합리적 선택-현상유지형’은 자활사업에의 참여가 자신의 상황을 고려한 합리적 선택이며, 현재의 상황이 악화되지 않는 것이 중요하다고 생각한다. 넷째, ‘만족-미래지향형’은 자활사업 참여가 생계에 도움이 되며, 궁극적으로는 자활사업을 통해 자립이 가능하다고 인식한다. 이 연구가 주는 함의는, 농촌지역 자활사업 참여자들의 특성에 부합되는 다양하고 차별성 있는 자활사업 프로그램의 도입, 도시지역에 비해 열악한 농촌지역 참여자들을 위한 자활 사례관리와 정서적・사회적 측면의 자활 프로그램이 요구된다는 것이다. This study intends to grasp the subjective perception of participants from rural areas on self-sufficiency project and, based on the perception types identified, to suggest the orientation of self-sufficiency projects in rural areas. With 31 statements related to self-sufficiency projects, Q sorting was conducted to 25 participants in rural areas. The results of Q factor analysis revealed the following four perception types. First, participants belonging to the type ‘Adjustment-Reality Satisfaction’ perceive that deliberation with their colleagues is very important, and that participation in self-sufficiency projects may help them overcome their current difficult situations but it is hard to expect that things will be much better after participation. Second, those who belong to the type ‘Dissatisfaction-System Improvement’ feel the importance of jobs matching each participant's capability and the need of differentiated self-sufficiency programs that would make it possible to enter the labour market. Third, the type ‘Rational Choice-Status Quo’ perceives that participation in self-sufficiency projects is a rational choice considering their current situation and finds it important to prevent worsening of their own situation. Fourth, the type ‘Satisfaction-Future Oriented’ believes that participation in self-sufficiency projects is helpful for their livelihood and ultimately will contribute to their self-reliance. Therefore, this study stresses the necessity of diverse and differentiated self-sufficiency project programs suited to the different characteristics of participants from rural areas, as well as the self-sufficiency case management for participants from rural areas which are disadvantaged compared to urban areas, and the adoption of self-sufficiency programs focused on emotional and social perspectives.

3D 모델링 프로그램을 활용한 인테리어 공사면적 산출에 대한 연구

하승범 국제문화기술진흥원 2023 The Journal of the Convergence on Culture Technolo Vol.9 No.1

Interior construction is required to estimate the quantity of material and the cost expected from 2D drawing in design phase and look for the reasonable method of work. Therefore, exact estimation for quantity and budgeting are very important processes, as a measure of judging the profitability of interior construction. These processes are mostly based on 2D drawing, so time and experienced staff are required. Error and omission can occur because the experienced staff also calculates the area using 2D based drawing. Interior market is currently based on 3D modeling from planning to final design. Accordingly, estimating quantity based on 3D modeling is emerging as a way of reducing error and omission. This paper will present the methodology on calculating area, the basic element of estimating quantity based on 3D Modeling in interior field. 인테리어 공사는 설계단계에서 2D 도면을 바탕으로 예상되는 자재물량을 산출하고 예상비용을 산정, 적정한 소요예산을 산출, 합당한 공사 방안을 모색하게 된다. 그러므로 정확한 물량산출과 예산책정은 인테리어 공사의 수익성 여부를 판단하는 척도로서 매우 중요한 과정 중 하나이다. 이러한 과정이 대부분 2D 도면을 기본으로 하기 때문에 시간과 경력직이 투입되는 것이 현실이다. 경력직 인원이라고 하더라도 2D를 기반의 도면을 이용하여 면적산출을 하기 때문에 오류와 누락이 발생한다. 현재 인테리어 시장은 3D 모델링을 기본으로 기획에서 최종 설계까지 진행되고 있다. 그래서 이제는 3D 모델을 기반으로 한 물량산출이 오류와 누락을 줄일 수 있는 방법으로 대두되고 있다. 그래서 이 논문은 인테리어 분야에서 3D 모델링을 기반으로 한 물량산출의 기본 요소인 면적산출 추출에 대한 방법론을 제시하고자 한다.

BIM 적용을 위한 기획설계 단계의 파라메트릭 디자인기법에 대한 연구

하승범 국제문화기술진흥원 2021 The Journal of the Convergence on Culture Technolo Vol.7 No.1

합리성과 효율성을 끊임없이 요구받고 있는 현대사회의 시대적 흐름은 사회 전체의 패러다임이 되었다. 이 패 러다임은 건축설계와 건설업계에도 큰 영향을 미치고 있다. 디지털 도구의 발전과 인터넷을 통한 정보기술 (Information Technology)로 대변되는 현대 기술은 건축설계와 건설업계에서 파라메트릭 디자인(Parametric Design)과 BIM(Building information Modeling)이라는 두 개의 큰 흐름을 생성하고 발전하고 있다. 비록 각기 다른 이유로 탄생했으나 효율성과 합리성이라는 공통의 목적으로 서로의 경계를 넘나들면서 건축설계와 건설업계에 큰 영 향력을 보이고 있다. 이러한 맥락에서 본 연구는 BIM 설계에 적용을 초기 기획설계단계에서의 파라메트릭 디자인이 어떻게 이루어져야 하는지에 대한 내용을 예시를 통해 구현해 보고자 했다. 해체주의(Deconstructivism) 건축가 “프 랭크 게리”(Frank O. Ghery)의 작품인 월트디즈니 홀(Walt Diseny Consert Hall) 설계의 프로세스에 대한 고찰과 체코프라하의 네덜란덴 빌딩(National Nederlanden Building)의 형태를 파라메트릭 설계 툴(Tool)을 사용하여 기획 설계단계에서의 형태를 구현하고자 했다. 향후 이 연구는 기획설계단계에서의 파라메트릭 디자인의 범위를 넘어서 궁 극적인 BIM의 적용 즉 계획 및 실시설계 그리고 시공에 이르는 건설산업 전반에 적용 가능한 기초 자료로서의 목적 에 사용되고자 한다. 향후 파라메트릭 디자인 알고리즘을 활용한 계획 및 실시설계단계에서의 BIM의 적용을 진행하고자 한다. Modern society needs constantly the rationality and the efficiency, and this flow of the time has become the paradigm of the whole society. This paradigm has a large influence on the architectural design and industry. Modern technology represented by the development of digital instrument and Information Technology through internet has created and developed two big trend, Parametric Design and BIM(Building information Modeling) in the architectural design and industry. These technologies, though created for different reasons, have a lot of influence on the architectural design and industry for a common purpose such as efficiency and rationality across the boundaries. In this context, this research will be embodied through the example about how parametric design should be made in the beginning of pre-design phase for BIM application. This research aims to consider the design process of Walt Diseny Consert Hall, the work of Frank O. Ghery, a deconstructivism architect, and to embody the shape of National Nederlanden Building in Prague, the Czech Republic, using parametric design tool in pre-design phase. This research later aims to be used as the basic data that can be applied to the entire architectural industry from a planning and a detailed design to a construction for the ultimate BIM application beyond the range of parametric design in pre-design phase. Later, the plan using the parametric design algorithm and BIM application in construction document phase will be conducted.
