An objective and valid knowledge activity indicator (KAI) is essential for encouraging knowledge activity in public institution. However, knowledge activity of public institution is inherently different from one of private corporation and, therefore, new method to find aggregated knowledge mileage considering public organizational culture and structure is to be developed. Therefore, this paper shows how to develop KAI of public institution based on three steps. First, knowledge activities were categorized as knowledge creation, knowledge sharing, and knowledge value increasing. Several knowledge indicators and hierarchical knowledge structure were developed for each knowledge categories. Second, personal knowledge mileage was calculated using AHP method considering whole organization's opinion. Finally, these approaches to find KAI were applied to "P" public institution as case studies. The results shows that KAI developed in this paper was very effective in grouping knowledge workers based on knowledge activities.

This paper presented the design of SRPS, ground function test, and the deployment test on a high speed taxi of KC-100 airplane. KAI has developed a spin recovery system in collaboration with Airborne Systems for KC-100 general aviation airplane. Spin mode analysis, rotary balance and forced oscillation tests were performed to obtain the rotational, dynamic derivatives in the preliminary design phase. Prior to the detailed design process of SRPS, approximations for initial estimation of design parameters- fineness ratio, parachute porosity, parachute canopy filling time, and deployment method- were considered. They were done based on the analytical disciplines such as aerodynamics, structures, and stability & control. SRPS consists of parachute, tractor rocket assembly for deployment, attach release mechanism (ARM) and cockpit control system. Before the installation of SRPS in KC-100 airplane, all the control functions of this system were demonstrated by using SBTB(System Breakout Test Box) in the laboratory. SBTB was used to confirm if it can detect faults, and simulate the firing of pyrotechnic devices that control the deployment and jettison of SRPS. Once confirmed normal operation of SRPS, deployment and jettison of parachute on the high speed taxiing were performed.

The purpose of this research was to ideatify and to trace the origin and meaning of jamokai(子母蓋). Comparative linguistic analytical approaches were used for the analysis of this study. Summaries of findings in this research are as follows : 1. There wese a number of phonetic value for jamokai (子母蓋) in Chinese. 2. The term, jamokai was derived from Hebrew. 3. The meaning of jamokai of Koryo was originated from Hebrew word meaning woman's veil. 4. The word jamokai was related to Perian, Arakic, Indian. 5. It is considered that tsi-ma-kai (치마개) was transliterated to tsi-m∂u-kai (子母蓋) in Chinese by the author of Keirim Yusa (鷄林類事). 6. The word jamokai (子母蓋) of Koryo was not related to Chinese.

본 논문에서는 HEVC 기술로 부호화된 비디오 비트스트림(HEVC 비트스트림)을 분석하고, 그 결과를 보여주는 방법에 대해서 제안한다.[1] HEVC 기술은 Coding Unit(CU), Prediction Unit(PU), Transform Unit(TU)을 기반으로 부호화가 이루어지므로 부호화 정보를 효과적으로 사용자에게 보여주기 위해서는 CU, PU, TU 를 기반으로 GUI(Graphic User Interface)가 디자인되어야 한다. 제안된 HEVC 비트스트림 분석기에서는 이러한 부호화 구조를 반영하여 사용자 친화적으로 HEVC 비트스트림의 부호화 정보를 편리하게 확인할 수 있도록 하였다.

항공기의 비정상적인 착륙 상황에서도 조종사의 생존을 보장하고 탈출에 방해되지 않도록 구조물이 설계되어야 한다. 추락 시, 화재의 원인을 찾는 연구를 시작으로 과거 수많은 고정익 항공기 추락시험이 수행되었다. 동역학적 분석을 통한 구조물의 거동특성을 이해하고, 가속도 상태에서 인체의 허용한계를 조사하여 적절한 추락하중배수가 설정되었다. 또한 화물기 사고 데이터를 확률론적 방법으로 분석하여 승객의 안전과 운용비용이 합리적으로 반영된 화물고정용 추락하중배수도 제시되었다. 과거 사례를 바탕으로 현재 적용되고 있는 추락하중배수의 물리적, 의학적, 경제적 의미를 살펴 보았다.

Yuan Shi Kai, the first President of the Republic of China, established a ceremonial uniform system based on ancient styles in 1914 just before the national polity was changed to the Empire of China in 1915. This system is Jisiguanfuzhi (a system on costumes for memorial services), and figures included in the system are Jisiguanfutu (figures showing costumes for memorial services). This study is the first to examine Jisiguanfuzhi and Jisiguanfutu and to approach the background idea of the establishment of the system with a focus on the meaning of 'unity.' Jisiguanfuzhi regulates the ceremonial uniform system of all classes from the President along with the 1st-class to the 5th-class people. The uniform consists of a crown, robe, belt, the mid-section cloth, and boots. In addition, the uniforms of ritual musicians and dancers are included. The basic principles in establishing the system were the restoration of ancient systems, the adoption of convenience, the acceptance of current practices, and the implication of symbolism. Jisiguanfuzhi clarifies that the pattern of the ceremonial uniforms was modeled on Juebianfu, for religious services. The reason for choosing Juebianfu for religious services was to achieve 'unity' and Juebianfu was associated with 'unity' because it was common to all, from the emperor to the gentlemen class, in ancient times. Yuan Shi Kai tried to show flexibility to the gentlemen class who represented the intellectuals at that time by adopting Juebianfu for religious services, fearing that the gentlemen class might oppose the attempt to restore the imperial system. Therefore, although Jisiguanfuzhi adopted mostly Mianfu and royal sacrificial robes, it also emphasized 'unity' by professing that the uniforms were based on Juebianfu for religious services.
