We propose, in this paper, a suggestion in terms of a series of solutions for the improvement of hardships and conflicts occurring in the building project collaboration especially in terms of building information exchange and cooperation among design-construction-investigation phases. We would explore and explain opportunities and circumstances provided by immersive video techniques and we propose solutions in terms of VR365 responding to the possible requests including geo-locating BIM data on the construction field views, real-time field survey reporting concurrent evaluation in design information based cooperation via BIM room collaborative review procedure. Our VR365 solution is the result of a series of refinements starting from version 1 IPAD based device for the implementation of concurrent evaluation to the version 2 of using VR360 immersive video techniques for spatio-temporal data of building projects. BIM room concept of Design Center is for the collaborative review.

This paper aims at design refinements in building energy performance and building forms by examining the co-relationships between those building forms (S Variables) and energy performances (B Variables) based upon design prototype theory and FBS design model. Hence we perform BIM modeling for a Neo-Hanok design prototype followed by the analysis of building design performance using building environment analysis tool. We then perform the design refinement process modeling applying the expert system shell for the design knowledge and and try to make it explicit for the implicit design knowledge used in those design reasoning process. We then examine the relationships between the improved building performance indices and design decision variables to validate the mappings between S and B variables in Design Prototype theory. Lastly we illustrate the running of the CLIPS expert system shell.

본 논문에서는 연자성 금속 분말인 sendust를 flake화 과정을 통하여 형상과 입도를 변화시켜 전파 흡수체를 제작하고, 그 특성을 분석하였다. 먼저 attrition milling에 의해 입도를 달리한 세 종류의 flake sendust 분말과 지지재인 CPE(Chlorinated Polyethylene)를 이용하여 전파 흡수체를 제작하고, 이 전파 흡수체로부터 재료 정수를 계산하여 입도에 따른 변화를 조사한 후 전파 흡수능을 측정하여 비교ㆍ분석하였다. 그 결과 평균 입도가 140 ㎛ 인 flake sendust 분말로 제작된 전파 흡수체가 와전류 손실의 감소(복소비 투자율 증가)와 입자간의 정전 용량의 증가(복소비 유전율 증가)에 기인하여 고주파 대역에서 우수한 전파 흡수능을 보임을 확인하였다. In this paper, we analyzed the characteristics of the EM wave absorber which was fabricated by using Flake Sendust (soft metal magnetic powder). The Flake Sendust was made of 3 different granularity by attrition mill. First, we have fabricated 3 kind of EM wave absorbers using the Flake Sendust and CPE(Chlorinated Polyethylene) and measured the S-parameters of the EM wave absorber. The complex relative permittivity and permeability were calculated from the measured data and the variations according to a change of granularity were researched. As a result, it was confirmed that the EM wave absorber using flake Sendust with the 140 ㎛ average granularity has outstanding absorption ability in high frequency range(C band) for the reduction of eddy current loss(increase of permeability) and the increase of space charge polarization(increase of permittivity).

BIM에 기반한 한국전통건축 원형의 곡형부재 응용

박수훈(Soo-Hoon Park) (사)한국CDE학회 2012 한국CDE학회 논문집 Vol.17 No.6

This paper starts with an approach to Korean traditional building design using BIM tool as a design methodology where Korean traditional buildings show some difference rather as weaknesses in handling curves and curved members and the construction. BIM design tools, that are adequate in treating modern architectural design vocabularies, show some disadvantages not having necessary elements and components as building libraries. In this paper we build our own libraries adequate to the proper assembling way of Korean traditional buildings. In contrast to the diverse use of straight building members, Korean traditional buildings show rare use of curves and/or curved members in their assemblage. Moreover, in the case of a circular plan, mostly a circle is interpreted in terms of polygons such as square, hexagon or octagon. In this paper, we examine Gwanram-Jung in Changduk Palace, which is probably the only example in Korea showing a use of curves and/or curved members in assemblage. We try to interpret the case as an incomplete prototype and apply in a modern way to complete a circular plan in terms of circular arcade.

박수훈(Soo-Hoon Park) (사)한국CDE학회 2013 한국CDE학회 논문집 Vol.18 No.1

The Yoon Jeung residence is a well-known and prototypical aristocratic house example showing typical and interesting characteristics of the traditional houses in the middle region of Korea. When it comes to understanding the architectonic characteristics of a Korean traditional house, it was not easy to actually capture the compositional and/or constructional knowledge of the building even though it is a wooden building with many wooden members showing their compositional relations. Now with the help of the BIM tool, the Building Information Modeling tool, we could actually be able to compare and analyze each member and their compositional relations. In this paper we examine the unique traditional composition method used in extending the building’s structural sections utilizing the bended-joint characteristics of traditional buildings with exemplar case of the Yoon Jeung residence. Thereby we examine those relationships among three major compositional parts namely the plan based spatial compositions, the upper wooden compositions and the roof forms so as to specify the building’s typical characteristics with reasonably acceptable causes. The inner and outer block of the residence are handled with their bended-joints with more detailed knowledge of categorization by way of joint relationships among members.

People evaluate urban residential regions quite frequently and sensitively, considering issues such as locations or ease of use of in-site facilities or nearby urban facilities, and those results are bound to be reflected to real estate costs quite immediately. However, there have been frequently recurring questions regarding objectivity of evaluations in terms of results and methods reflected on indexes such as land costs for various reasons. RPMS -Residence Performance Management System- which targets currently in most cases on urban residential areas, suggests instrumental methodology of objective approach toward sensitive urban residence performance evaluation. This paper explains and suggests instrumental utilization of RPMS and its implementations, evaluation methodology and quantitative way of evaluation. In terms of implementation we explain issues such as adding target locations into new residence planning sites, quantification of properties on evaluation indexes of residential performance and/or habitability in terms of checklists, formulas for evaluation, delicate adjustment of evaluation results by setting weights on evaluation indexes, as well as reports on results. Research on appropriate weights and weight settings regarding evaluation indexes, however, exceeds the range of this paper so that this paper focuses on explaining residence performance evaluation and management methodology.

본 논문에서는 RFID Tag가 금속판에 접근할 때 통신 거리가 감소되는 RFID 시스템의 통신 거리 증대를 위한 전파흡수체를 개발하였다. 먼저 자성 손실 재료인 Amorphous 금속 분말과 지지재인 CPE(Chlorinated Polyethylene)를 이용하여 조성비별 전파흡수체 샘플을 제작하고, 이 전파흡수체 샘플로부터 구한 재료정수를 이용하여 전파흡수능이 서로 다른 전파흡수체를 각각 설계?제작하였다. 이와 더불어 개발된 전파흡수체를 적용하여 금속에 의해 특성이 열화되는 RFID 태그 안테나의 특성 개선 효과 및 실제 RFID 시스템의 통신 거리 변화를 실험적으로 검토하였다. 그 결과 조성비가 Amorphous metal powder:CPE=80:20 wt.%이고, 두께가 4 ㎜인 전파흡수체가 금속판으로 인해 통신 거리가 0.8 m인 실제 RFID 시스템의 통신 거리를 5.2 m까지 증대시킴을 확인하였다. In this paper, we designed and fabricated the EM wave absorbers for preventing the reduction of the communication range when RFID Tag is approached to a metal plate. The EM wave absorber samples were fabricated with difference composition ratios of Amorphous metal powder and CPE, the absorption abilities of which were simulated by substituting different thicknesses of the EM wave absorbers. Then the EM wave absorbers are manufactured based on the simulated results. By using the EM wave absorbers, we have confirmed the improvement effect of RFID tag antenna and the increase of communication range of RFID system. As a result, it was cleary shown that the communication range of RFID system is improved by adopting the EM wave absorber with the composition ratio of Amorphous metal powder:CPE=80:20 wt.% and the thickness of 4 mm. Thus, it was confirmed that the proposed EM wave absorber can increase the communication range of RFID system from 0.8 m to 5.2 m in UHF band.

전기적으로 빠른 과도현상/버스트 신호의 복사방출과 대책

박수훈(Soo Hoon Park),김동일(Dong Il Kim),박연준(Youn Joon Park),나승욱(Seung Wook Nah) 한국전자파학회 2016 한국전자파학회논문지 Vol.27 No.3

본 논문에서는 전자파적합성 국제 규격인 IEC 61000-4-4에서 규정하고 있는 전기적으로 빠른 과도현상/버스트(EFT/Burst) 신호가 전원선을 따라 시험대상품에 인가될 때, 인가신호에 기인하여 방사되는 불요전자파와 그 신호가 피시험품에 미치는 영향에 대해 연구하였다. 먼저 국제규격에 규정된 시험 배치방법에 따라 시험 샘플을 설치하고, 검증된 EFT/Burst 발생기로 1분 동안 +4 ㎸의 규정된 신호를 길이 1 m인 전원선을 통해 시험 샘플에 인가하였다. 그 결과, 전원선을 통해 인가되는 전도성 EFT/Burst 내성 신호 외 버스트 발생기 및 전원선에서 직접 공기 중으로 방출되는 방사성 신호(EFT/Burst 노이즈)가 검출되었고, 국제 공인시험 규격으로 이 신호를 측정한 결과, 규제 레벨보다 30 ㏈ 이상 높았다. 또한, EFT/Burst 방사성 신호의 최대 방사 지점과 시험품의 이격 거리에 따른 전계강도를 측정한 결과, 방사내성 국제규격치보다 최대 23 V/m 이상 강한 전계강도가 검출되었다. 이는 EFT/Burst 방사성 노이즈가 직접적으로 제품에 인가되어 오동작을 유발할 가능성이 대단히 높으므로 대책이 요구됨을 확인하였다. In this paper, we studied about the radiated emission of EFT(Electrical Fast Transient)/Burst signal, referenced IEC-61000-4-4 of the international EMC standard and its effect on EUT(Equipment Under the Test) when EFT/Burst signal (Conducted noise) induced on a power cable to EUT. Firstly, we set up test sample by the standard and +4 ㎸ standard signal is induced by EFT/Burst signal generator with 1 m length power cable for 1 minute. Consequently, we found not only induced EFT/Burst signal along power line, but also directly radiated emission signal from EFT/Burst signal generator (Radiated emission noise of EFT/Burst). The radiated emission signal of EFT/Burst was 30 ㏈ which is higher than limit of CISPR 22 which is international EMC standard. Moreover, we measured the electric field strength by changing distance from maximum radiated emission point to electric field strength tester. As a result, this electric field strength was 23 V/m which is higher than international EMC standard test level(CISPR 24). Therefore, it was confirmed that the probability of malfunction may be high when radiated emission of EFT/Burst noise exists near the EUT.
