ERTMS/ETCS Baseline 3 요구사항 및 기능분석
남하일(Ha-Il Nam),강성원(SeongWon Kang),강덕원(DeokWon Kang),박성호(SungHo Park) 한국철도학회 2016 한국철도학회 학술발표대회논문집 Vol.2016 No.5
2000년대 초반에 정립되어 몇 차례 개정된 Baseline 2는 2.3.0을 마지막으로 더 이상 개정되지 않고 있으며, Baseline 2에서 여러 이슈사항으로 인해 논의에서 제외되었던 주제 및 새로운 기술이론을 반영한 Baseline 3가 2006년 발표되어 현재 3.4.0까지 개정되었다. Baseline 2 의 최신개정본인 2.3.0d(2.3.0에 subset 108을 추가한 개정본) 대비 Baseline 3의 최신개정본인 3.4.0은 총 436개의 변경요청사항(CR)이 반영된 것을 확인하였다. 이것을 국내에 적용된 ERTMS/ETCS를 고려하여 분석하기 위해 두 Baseline의 호환성을 분석하였고, 기능개선사항 및 요구사항 목록을 각각의 Baseline에 대해 상세하게 비교 및 검토 하였다. 더 나아가 향후 국내에 Baseline 3 적용 시 참고가 될 수 있게 현재 유럽 주요국들의 Baseline 3 추진동향분석도 수행하였다. Baseline 2 which have been revised since early this decade is not revised anymore after 2.3.0 release, Baseline 3 which is considered new technical issues and couldn’t consider in Baseline 2 because of several issues have released since 2006. The latest version of Baseline 2 is 2.3.0d(original version 2.3.0 with Subset 108) and Baseline 3 is 3.4.0. Compare with these two version, there are total 436 CR(Change Request)s. In order to analyze these two versions(consider KOREA ERTMS/ETCS circumstance), compatibility analysis of two versions, comparison/analysis of specification lists & improvement of functions and latest trend analysis of ERTMS/ETCS baseline 3 plan in Europe are performed.

Background : Osteoporosis and atrophic cell pattern in Pap smear are frequent findings In postmenopausal women due to loss of ovarian function, The present study attempted to find out possible correlation between morphologic characteristics of Pap smear and osteoporosis. Material & methods: The subjects were 825 women(age from 35 to 80) who had undergone Pap smear and bone mineral density(BMD) at The Korea Association of Health Promotion, Seoul Branch, from March 8 to May 10, 2005. Pap smears from 825 women were reviewed and classified either mature cell pattern or atrophic cell pattern by their cytologic patterns, BMD were measured using LUNAR DPX MdIQ(Minster, Ohio, USA). BMD value of lumbar spine(Ll, L2,L3 and L4) were measured from 825 women and BMD value of proximal region off emur(neck NK, Wards triangle WT, and trochanter TR) were measured from 818 women and their bone status were classified as normal( T-sore:>-1.0), osteopenia (T-score: -l~<-2,5) and osteoporosis(T-score: ≤ -2.5). And age distribution of Pap smear, average T-value andfrequency ofsteoporo-sis of each region of the bone, percentage of osteoporosis of each boneregion by age group and changing pattern of percentage of osteopenia and osteoporosis in certain postmenopausal period were compared between mature and atrophic cell pattern. Results: Pap smears revealed total mature cell pattern 53,9%(445/825) and total atrophic cell pattern 46.1%(380/825), Percentage of mature cell pattern decreased from 98.2%(168/171)under 44 age group to 13,3%(17/128) over 65 age group and mature cell pattern increased from 1.8%(3/171) under 44 age group to 86.7%(111/128) oyer 65 age group. Mean T-value of each region of lumbar spine and femur of mature cell pattern were lower than that of atrophic cell pattern about -1,5. And osteoporosis has noted in atrophic cell pattern showing odds ratio Ll 13.9, L2 15.3, L3 12.0, L4 10,4, UK 6.7, WT 10.9 and TR 4.1.Atrophic cell pattern started to increase after 45 years of age and osteoporosis of a trophic cell pattern started after 55 years of age. During 50 to 64 years of age period, L3, L4 and WT revealed parallel increased of osteopenia and osteoporosis and Ll, L2 revealed decreased of osteopenia and increased of osteoporosis. nia Conclusion: Above findings suggest that atrophic cell pattern of Pap smear precedes osteoporosis about 10 years and one of predictor of osteoporosis.

BIM 기반 Set-based Design 적용 방안에 관한 연구
이승일(Lee Seung-Il),권남하(Kwon Nam-Ha),조영상(Cho Young-Sang) 대한건축학회 2011 大韓建築學會論文集 : 構造系 Vol.27 No.7
Recently, Construction projects have become larger and more sophisticated. It makes efforts to construction productivity improvement in domestic and international construction industries. There are still researches that Lean Construction, Building Information Modeling(BIM), Integrated Project Delivery(IPD) for productivity improvement. The initial step of design is important for construction project to productivity advancement, information exchange and collaboration. Point-based design(PBD) starts from a somewhat arbitrary initial point in the parameter space of all possible solution. The solution is then optimized, one step at a time, at each step moving to a more desirable point in the parameter space. The goal is to find the optimal solution point, although it is not obvious that this point will ever be reached. By contrast, Set-based design(SBD) based on lean design is an approach that defers design to the last responsible moment to allow for the evaluation of alternative that improve constructability. SBD involves deep thinking at each level of design for system, subsystems, assemblies, and components. By having decisions made at the last responsible moment, set-based design avoids loop backs that may need to be made later because of hasty decisions, as past issues have to be revisited. Structural Building Information Modeling(S-BIM) is process that focus on structural engineering in BIM process. It provides flexible environment of interoperability and collaboration with relevant area included structural engineering thanks to containing necessary structural information. Especially, Analytic Hierarchy Process(AHP) of the decision making processes is improved decision’s reliability by using S-BIM that considers economics, constructability, structural safety, etc. This study proposes application methodology for set-based design of AHP in the structural BIM environment that performs case study through high-rise building project of outrigger system.
