  • This paper investigates the thermal storage performance of the office building which has adopted an air conditioning system with its slab structure as a regenerator. Four cases of the thermal storage performance experiment were conducted. Room air temperatures, floor slab temperatures, temperatures around the air conditioning unit were logged and analyzed. The load handling capacity of the air conditioning unit and the amount of heat stored in the slab were decided from those experiments. Several efficiencies were investigated to evaluate the performance of the thermal storage. The results concluded that the slab as a regenerator is very effective in cutting down peak loads of the office building.

  • This paper proposes a framework for understanding the energy consumption differences between tall and low-rise buildings. Energy usage data from 706 office buildings in New York illustrates expected correlations from the framework. Notable correlations include: taller buildings tend to use more energy until a plateau at 30~39 floors; tall buildings in Manhattan use 20% more energy than low-rise buildings in Manhattan, while tall buildings outside Manhattan use 4% more energy than low-rise buildings outside Manhattan. Additional correlations are discussed, among which is the trend that the Energy Star program in New York City assigns higher ratings to tall buildings with higher EUIs than low-rise buildings with the same EUI. Since Energy Star is based on regressions of existing buildings, the Energy Star ratings suggest taller buildings have higher EUIs than shorter buildings, which is confirmed by the New York City energy benchmarking data.

  • Path loss plays fundamental roles in system design, spectrum management, and performance evaluation. The traditional path loss model has a slight inconvenience; it depends on the unknown distance. In this letter, we explore the probability distribution function (PDF) of path loss in an indoor office environment by randomizing out the distance variable. It is shown that the resulting PDF is not Gaussian-like but is skewed to the right, and both the PDF and the moments are related to the size of the office instead of the unknown distance. To be specific, we incorporate the IEEE 802.15.4a channel parameters into our model and tabulate the cumulative distribution function with respect to different room sizes. Through a simple example, we show how our model helps a cognitive spectrum user to infer path loss information of primary users without necessarily knowing their transmitter-receiver distance.

  • The purpose of this study was to evaluate the usability and satisfaction of space to which positive elements in Leed-Certified Office Building are applied. The study was conducted using the three-step approach. The first step was to understand the building and identify the issues which included the analysis of floor plans, documentations, and the interview with designers and facility managers. The second step was FGI(Focus Group Interviews), which were conducted with mixed employees of rank and location of workplace. Finally, a web-based questionnaire survey was conducted on the 319 executives and employees. Methods of analysis used were quantitative analysis of questionnaire, qualitative analysis of open ended free-answer, and FGI in the second step. Satisfaction, preference, and comfort level were studied using cross tab, co-relation, ANOVA for quantitative analysis. The results of this study are as follows: First, lobby and atrium are representative elements that are functioning positively and it is recognized as sustainable spaces being utilized by users. Second, there are several dead spaces like green shaft, roof garden and sunken space although they can contribute to Leed-certification. Third, there are some problematic spaces such as the O.A. room and the urinals even though they contribute to the Leed-certification.

  • The purpose of this study is to understand the architectural space of Gwolnaegaksa (闕內各司), the Government office in the palace, in the early Joseon Dynasty. The Royal palace can be divided into three parts, political space for king, living space for king and his family and government office. So first, we should to understand the characteristics of each space in the Royal Palace. Up to now we have looked at the architectural space of Gwolnaegaksa in Gyeongbokgung (景福宮), one of the Royal Palace, the result of this study is as followings. There were not many Gwolnaegaksas in the early days in Gyeongbokgung. After King Sejong, some office buildings were established in that palace. King's closest guards, like as Seonjeonkwan (宣傳官), Gyumsabok (兼司僕), Naegeumwi (內禁衛) had been on duty in Sajeongjeon Haengrang (思政殿 行廊), a kind of servants' quarters. Bincheong (賓廳), a conference room of high-ranking government officials was situated in Geungjeon Haengrang (勤政殿 行廊). There were also barracks of other palace guards in Geungjeon Haengrang. Gyeongyeoncheong (經筵廳), a place to prepare and wait, was built separately from Geungjeon Haengrang Layout drawings of Gyeongbokgung painted since the 18th century were different from document in some parts. The arrangement of the Gwolnaegaksa was assumed like as the Fig. 9.

  • The purpose of this study is to understand the architectural space of Seungjeongwon (承政院), the Royal Secretariat, in the early years of Joseon Dynasty. The Royal palace can be divided into three parts, political space, living space for king and his family and offices for government official in the palace. So first, we should to understand the characteristics of each space in the Royal Palace. The result of this study is following. Seungjeongwon of the Joseon Dynasty was where Seungji (承旨), Juseo (注書), Sagwan (史官), Seungjeonsaeg (承傳色), Seori (書吏) and Harye (下隷) worked together. The architectural space of Seungjeongwon was separated into Jeongwon-Cheong (政院廳) and Juseo-Cheong (注書廳). Jeongwon-Cheong was the office for Seungji, where Sagwan worked as well as Seungji and Juseo. The form of Jeongwon-Cheong (政院廳) in Kyung-bok Palace was similar to that depicted in Eundaegyecheop (銀臺契帖), which was painted the meeting of Seungjis. Juseo-Cheong was the office for Juseo and Sagwan and there was a break room. Apart from Jeongwon-Cheong there were rooms where Seungji could work or take a rest. As with the office of Seungji, the space for Juseo also had rooms for Juseo. There were also rooms for Seori and Abang (兒房) which were rooms for servants.

  • The air sterilization systems are investigated experimentally in this paper. The goal is to reduce bacteria, mold and viruses in office air by using a UV sterilizer installed inside a partition panel and wall-mounted unit. These systems allow occupants to turn the system on/off and to control the incoming air speed and direction. The partition air sterilization system conditions and sterilizes the air, and then delivers the clean air into the personal task area through the partition panels, which are connected to the pressurized under-floor plenum. Room air exits through the return grills mounted on the ceiling. The wall-mounted air sterilization system sterilizes the air, and then delivers the clean air to the personal task area from the wall. In this study a full-size experimental environment is established to investigate the immunization performance of these air sterilization systems. A typical office space scale is used in this study in order to find an optimal system to achieve a sterilized healthy micro-environment. Multiple system parameters, including volume flow rate and velocity of supplied air, were regulated during the experiments. The more air contact these air sterilization systems had, the better disinfection performance. Over 90% of eradication ratios were obtained by these two air sterilization systems. The results indicate that these systems can efficiently disinfect office air contamination.

  • In order to present the enhancement direction for the military administrative facilities, that can satisfy the user demands and achieve cost-effectiveness the goal of public projects, this research analyzes the features of functional spaces using Analytical Hierarchy Process(AHP). Basically, the scope is selected to four facilities commander office, private office, public office, and meeting room, because they have an effect on military administrative facilities. Since the space is established by a combination of their own functions, this research begins with an analysis of functional spaces of military administrative facilities, which is verified through literature review and interview with expert. Thereafter, an AHP survey is conducted to military personnel to analyze the priority of functional spaces and to re-classify the functional spaces of each Military administrative facilities. Resultingly, the difference of functional spaces preference according to ranks and facility type are identified. Even though the same military facilities, it means that user satisfaction is different. Therefore, user satisfaction should be considered for each facility at the construction plan. It can minimize overlapped and unused spaces, which can help ensure cost-effectiveness. Consequently, this research suggested the methodology and the process that can take user satisfaction and can support the enhancement of military facilities standards.

  • 형사조정제도에 대해 우리나라에서는 2006년 4월 대전지검 등 3개청에서 범죄피해자지원센터 주관 시범 운영되다가 2007년부터는 전국57개 지방검찰청 및 지청에서 범죄피해자센터와 형사조정제도를 본격 실시한 이래 2016년 현재는 모든 검찰청에서 형사조정제도를 운영하고 있다. 한편 검찰에서는 2009년 10월 '형사조정 실무운영 지침'을 제정하고 2010년 9월에 "범죄피해자보호법"에 그 법률적 근거를 마련하였다. 이는 형사조정이 범죄피해자 피해 회복을 지원하는 방향으로 운영되어야 한다는 것을 담고 있다고 본다. 그러나 형사조정제도의 전반적인 인프라는 어느 정도 구축되어 있다고 볼 수 있으나, 본 필자가 2007년부터 2016년 현재까지 G검찰청 형사조정위원 활동을 통하여 경험한 바로는 아직도 형사조정실 신변안전에 대한 취약 등 몇 가지 문제점이 대두된바, 본 논문에서 그에 대한 문제점을 검토하고 형사조정 실무에 알맞은 형사조정제도의 개선방안을 제시하고자 한다.
