최근 에너지 효율이 높은 분리 공정기술의 수요가 증가하면서 분리막을 이용한 기체 분리가 큰 관심을 모으고 있다. 현재 분리막에 의한 기체 분리 시장은 고분자막이 독점하고 있으며, 고분자 재료 물성의 한계로 탄화수소와 같은 응축 기체분리보다는 비응축 기체 분리에 제한되고 있다. MOF 재료는 금속 이온과 유기 리간드가 결합하여 형성하는 결정성 나노 기공 구조로, 높은 비표면적과 기공 구조 제어, 기능성 부여가 가능해 분리막 재료로 큰 관심을 끌고 있다. 본 총설에서는 다양한 MOF 분리막의 합성 방법과 MOF 분리막을 통한 기체 분리 응용에 대해 살펴보고자 한다.

구조의 기하학적 비선형해석을 위해 대표적으로 Total Lagrangian, Updated Lagrangian 정식화 기법이 있다. 이러한 고전적인 정식화 과정은 요소의 변형률을 가정하는 방법에 따라 그리고 요소의 절점 수에 따라 추가의 수학적 정식화 과정이 요구된다. 하지만 비교적 최근에 정립된 Co-roational(CR) 이론은 기 존재하는 보, 판, 쉘 요소에 독립적으로 요소 절점자유도에 따라 일정하게 적용하여 대변위, 작은 변형률을 갖는 구조의 기하비선형 해석을 가능케 한다. 본 논문에서는 회전자유도를 갖는 삼각평면요소에 대한 CR 기법을 정식화하였고 동적해석으로 확장하여 이를 상용프로그램과 검증하였다. 해석에 사용한 삼각평면요소는 OPtimal Triangular(OPT) 평면요소이다.

We present the current status (as of August 2014) of SPICA (Space Infrared Telescope for Cosmology and Astrophysics), which is a mission optimized for mid- and far-infrared astronomy with a cryogenically cooled 3m-class telescope. SPICA is expected to achieve high spatial resolution and unprecedented sensitivity in the mid- and far-infrared, which will enable us to address a number of key problems in present-day astronomy, ranging from the star-formation history of the universe to the formation of planets. We have carried out the "Risk Mitigation Phase" activity, in which key technologies essential to the realization of the mission have been extensively developed. Consequently, technical risks for the success of the mission have been significantly mitigated. Along with these technical activities, the international collaboration framework of SPICA has been revisited, which resulted in la arger contribution from ESA than that in the original plan. To enable the ESA participation under the new framework, a SPICA proposal to ESA is under consideration as a medium-class mission under the framework of the ESA Cosmic Vision. The target launch year of SPICA under the new framework is the mid-2020s.

Planetary nebula in elliptical galaxies pose a problem in dark matter theory. Using data from the Planetary Nebula Spectrograph (PN. S), Romanowsky et al. (2003) reported that less dark matter than expected was found within 5 to 6 effective radii of three elliptical galaxies. We attempt to explain similar observations of elliptical galaxies with MOdied Newtonian Dynamics (MOND). We collect 16 elliptical galaxies with planetary nebulae from the public web data of PN. S. We investigate the dynamical behavior by analyzing the line-of-sight velocity dispersion in the framework of MOND.

This study is conducted to suggest ways to mitigate the mismatch phenomenon between job seekers who want to find right company for themselves and companies looking for appropriate new employees. For this purpose, this study improves the company assessment framework reflecting job seekers interests by using fuzzy analytic hierarchy process. The improved evaluation framework is a three-level hierarchical structure, where there are 4 groups at the top level, 12 factors at the intermediate level and 36 indexes at the bottom level. For the empirical analysis of the applicants preferences based on the improved model, a survey for F-AHP analysis is carried out to university students and then priorities of components in the evaluation model are calculated. Moreover, the differences of priority of the company assessment framework are analyzed for different genders, college years, and major divisions. The results show that job seekers’ most concerning factors are wages, stability, working environments, and labor deal, which are ranked highly in this order and the differences in preferences for each type of job seekers (genders, college years, and major divisions) are obvious. The results also show that the male prefers wages to environment, on the other hand female does working environment to wages.

Successful development of weapon systems requires a stringent verification and validation (V&V) process due to the nature of the weapons in which continual increase of operational capability makes the system requirements more complicated to meet. Thus, test and evaluation (T&E) of weapon systems is becoming more difficult. In such a situation, live fire tests appear to be effective and useful methods in not only carrying out V&V of the weapon systems under development, but also increasing the maturity of the end users operability of the system. However, during the process for live fire tests, a variety of accidents or mishaps can happen due to explosion, pyro, separation, and so on. As such, appropriate means to mitigate mishap possibilities should be provided and applied during the live fire tests. To study a way of how to accomplish it is the objective of this paper. To do so, top-level sources of hazard are first identified. A framework for T&E is also described. Then, to enhance the test range safety, it is discussed how test scenarios can be generated. The proposed method is based on the use of the anticipatory failure determination (AFD) and multiple event tree analysis (ETA) in analyzing range safety. It is intended to identify unexpected hazard components even in the environment with constraints. It is therefore expected to reduce accident possibilities as an alternative to the traditional root-cause analysis.

This paper addresses order-lot pegging issues in the supply chain of a semiconductor business. In such a semiconductor business (memory or system LSI) order-lot pegging issues are critical to achieving the goal of ATP (Available to Promise) and on-time production and delivery. However existing pegging system and researches do not consider capacity limit on bottleneck steps. This paper presents an order-lot pegging algorithm for assigning a lot to an order considering quality constraints of each lot and capacity of bottleneck steps along the entire FAB. As a result, a quick and accurate response can be provided to customer order enquiries and pegged lot lists for each promised orders can be shown transparently and short or late orders can be detected before fixing the order.

Many systems using RFID/USN were and are being developed. Some systems are used in practice and some are not. Generally, the main reasons not being used are: The prices of chips are too high considering the effects. The application domain is not appropriate for RFID/USN. So, various skills for higher sensing precision have been introduced like using multiple sensors and avoiding metals which deter sensings seriously. Now, it is time to evaluate systems which were developed using RFID/USN technology. However, no systematic approach has been made for the evaluation. In this paper, a framework using BSC is introduced for the evaluation of systems using RFID/USN. In this framework, some Critical Success Factors(CSF) are derived and some Key Performance Indices(KPI) are developed for each CSF.

This paper presents a parallel kd-tree traversal algorithm based on the parallel binary radix tree construction scheme proposed by Tero Karras in 2012. In his paper, Tero Karras proposed parallel tree construction algorithm which can maximize the utilization of GPU threads, but implementation and analysis of kd-tree are not fully discussed. This paper aims to fill the gap for the specific kd-tree cases. As an application for the kd-tree traversal method proposed in this paper, the proposed method has been implemented with NVIDIA’s CUDA framework and tested on NVIDIA’s realtime raytracing library, OptiX. As a result, the proposed method can construct tree structures within the requirement for realtime process, but still needs specialized spatial caching data structure like the “primitive tree” for highly detailed meshes to handle spatial queries as fast as to visualize implicit surfaces under OptiX framework. However, the proposed method can be applied to dynamic collision detection and manage scene and object information for game applications thanks to its fast tree construction process. Also, realtime raytracing can be applied to game applications based on this study.

New product promotion is an expensive and time-consuming process that suffers from a high failure rate. Scholars have examined the relationships between product introduction and sales force management, but the importance of the sales force in selling new products can still be further explored (Fu, Richards, , Hughes, , & Jones, 2010; Spanjol, Tam, Qualls, & Bohlmann 2011). The purpose of this paper is to examine the influence of perceived sales management controls on a salesperson’s new products sales performance (i.e., electronic goods) in a business-to-business context. In addition, the direct, mediated, and moderating influences of market orientation on sales performance will also be investigated.Through the literature reviewed (e.g., Evans, Landry, Li, & Zou, 2007; Matsuo, 2009; Matear, Osborne, Garrett, & Gray, 2002), this paper proposes its hypotheses. In terms of the antecedents of sales performance, this research focuses on the effects of innovativeness (Matsuo, 2009). Second, based on the works of Evans et al. (2007) and Matsuo (2009), this study proposes that management controls (i.e., behavior-based control, knowledge-based control, and output-based control) both directly and indirectly affect sales department performance by first influencing innovativeness. Third, this research intends to examine the effect of organization psychological climate, which is market orientation, on the innovativeness and performance of sales departments (Matear et al., 2002). Finally, this study investigates the moderating effects of an organization’s market orientation on the relationship between sales innovativeness and performance (Matear et al., 2002).EMBA and MBA students were recruited as interviewers to gather data. The companies involved in this study were electronics product manufacturers that were publicly listed on the Taiwan Stock Exchange. A total of 315 complete responses were obtained. The target research question was “what are the determinants of a sales department’s new product sales performance?” This study used partial least squares (PLS) to examine the proposed model.This research found that sales department innovativeness is positively linked with new product sales performance. For the effectiveness of management controls, the results show that sales management controls (i.e., output-based control, behavior-based control, and knowledge-based control) positively affect department innovativeness but cannot influence performance directly. As for marketing orientation’s influences, this current research confirmed an organization’s market orientation-ness cannot positively affect sales department’s innovativeness and performance when selling new product. However, market orientation can positively moderate the relationship between innovativeness and performance. Based on the findings of this research, managerial implications have been put forth.
