The purpose of this study is to compare the key research-related constructs, research insterest, research self-efficacy, research productivity, and research outcome expectation of the graduate students, who are participating in Global Ph.D Fellowship (GPF) and Brain Korea (BK) 21 projects. The overall results show that the mean scores of GPF students in research interest, research self-efficacy, research productivity, and research outcome expectation are higher than those of BK21. However, the higher mean scores of doctoral students in both GPF and BK21 projects imply that the longer you stay in graduate program, the better researcher you can be. Although GPF program selected higher potential students and they seem to work very hard with high expectation to be competent researchers, compatible outcome also could be possible by BK21 project.

The purpose of this study was to investigate the process and the effect of pre-service teacher's scaffolding in environmental camp program about global climate change. For this study, developed the environmental camp program based pre-service teacher's scaffolding and applied to 78 $5^{th}$ students. We analyzed the role of pre-service teacher in the process of scaffolding. In the result, the pre-service teachers conducted cognitive scaffolding like as "Focus", "Hint", "Tell or Summarize" and "Technical Help". They carried out the emotional scaffolding like as "Create Cheerful Atmosphere", "Encourage", and "Help in Living". Teaching and learning about global climate change, the theme of the camp, was regarded uncertain and complex. So, pre-service teacher's scaffolding was effective to promote environmental literacy about climate change of primary students (<0.05). The student teachers understanded the characteristics of the children through emotionally close relationships. The primary students were learned easier about global climate change through cognitive and emotional scaffolding. They experienced environmental practice with communal living in camp.

Recently, in the movie theater, the special chair is installed to maximize the viewing effect of movies. It is structured to convey a vibrational stimulus to a specially-designated parts of human body by attaching a vibration transducer to a existing theater chair. This paper describes the analysis of the vibration transfer characteristic of a foaming sponge seat for the design of the special chair. We could not apply the structural analysis S/W because it is difficult to obtain the mechanical properties and damping coefficients of the various type sponges. And then we computed the transfer functions by the global curve fitting program based on experimental modal analysis. The experimental response results comparatively coincide with those by the global curve fitting program. We also could obtain the natural frequencies, the modal damping coefficient ratio, the modal vectors and the whole transfer functions. Therefore we could analyze the dynamic characteristic for design of foaming sponge seat.

After introduced in 1980's, the Frequent Flyer Program(FFP) was one of the most successful marketing tools in the airline industry and it has become a major linkage pin of strategic alliances for airlines despite of legal constraint. Further, the world air transport market progresses rapidly from a one-to-one alliance to a global alliance among groups due to fierce competition of the markets. In this study, I first examine the trends and the characteristics of global alliance groups. Further, I analyze the types of airline strategic alliances in the FFP, and present management strategy of the FFP for national flag carriers based on the collected data. It is suggested that airlines, including the two major Korean airline companies, consider the advantages of strategic alliances on the FFP in a rapidly changing management environment.

제3차 영재교육진흥종합계획을 통하여 소외계층을 대상으로 한 영재교육의 활성화가 진행되었다. 이에 따라 전체 학생 중에서 영재교육의 대상자 수의 비율도 증가하였으며, 영재교육 대상자 중 소외계층의 비율도 증가하였다. 일반 영재학생과 다르게 소외계층 영재 학생은 경제적, 문화적, 지리적 어려움을 겪고 있으므로 다각적인 지원이 필요하다. 하지만 선행 연구에서는 소외계층의 중학생을 대상으로 한 교육 프로그램 개발연구가 부족한 것으로 나타났다. 따라서 본 연구에서는 소외계층 중학생을 위한 온라인 교육 프로그램을 개발하였다. 교육 프로그램은 총 20차시이며, 2015 개정 교육과정의 과학, 수학, 정보 교과의 교육 내용을 기반으로 주제를 추출하였다. 추출한 주제를 기반으로 기초-심화로 이루어진 온라인 교육 콘텐츠를 개발하였으며, 교과별 역량 개발을 위하여 탐구 과제를 구성하였다. 향후 연구에서는 본 연구에서 개발한 교육 프로그램을 소외계층 학생을 대상으로 운영하고, 프로그램의 만족도와 개선 방향을 도출하고자 한다. 또한, 교육 프로그램의 교육적 효과를 알아보기 위하여 사전, 사후 검사를 통하여 학생들의 변화를 관찰하고자 한다.

Exploring the vicinity of super-massive black holes (SMBHs) is one of the frontiers in astrophysics. KaVA AGN Science WG has launched its Large Program in 2014 focusing on two SMBHs, Sgr A∗ and M87. They are selected based on their large apparent size. Sgr A∗ is the excellent laboratory for studying gas accretion process onto SMBH and M87 is well known as the best case for investigating plasma outflow ultimately driven by SMBH. For Sgr A∗, KaVA and EAVN provides superb UV-coverage on its emitting region and its scattering medium. In the case of M87, we have conducted high cadence dual-frequency (22and 43GHz )VLBI monitoring to clarify the global profile of the M87 jet velocity field and the spectral index map, which should reflect global structure of magnetic fields in the jet. From 2017, the AGN LP is recognized as multi-wavelength EHT project, conducting quasi-simultaneous coherent observations of M87 and Sgr A∗ with the Event Horizon Telescope (EHT) during its campaign observation periods. AGN WG is reviewing and revising its LP to convert it to EAVN LP. We will briefly report our scientific results and future plan which includes even broader international collaboration, namely East-Asia to Italy Nearly Global (EATING) VLBI to reach higher angular resolution.

The metal lead frame, a semiconductor component, has product tolerances in micro units as compared to products made with a larger size mold. Therefore, small deflections of the mold and of the press as well as the press molding process itself have a strong influence on accuracy of the product. Hence, it is necessary for the process design to consider the structural response of the mold and the press during deformation. In the current study, the mold deflection and pressure on the punch is examined using the finite element modeling (FEM) program ABAQUS. The results from the simulation were verified with the dynamic deformation measurement equipment using digital image correlation (DIC).

Gold-catalyzed tandem cyclization-oxidative alkynylation and cyclization-fluorination reactions of 2-alkynone O-methyloximes are described. The reactions proceed smoothly at room temperature in the presence of 10 mol % of $(PPh_3)AuNTf_2$, 2.5 equivalents of selectfluor, and 2 equivalents of $K_3PO_4$. 2-Alkynone O-methyloximes undergo intramolecular oxyauration/cyclization and ensuing oxidative cross-coupling and fluorination process to afford the corresponding 3,4,5-trisubstituted isoxazoles in a cascade manner.

A new glut bel routing technique for gate array is described in this paper. In former global routers the position of pins is considered to be in the center of the cell. So it is impossible to exactly estimate the number of signal lines passing through each channel. As a result, an overflow occurs and the overflow violates 100% wiring in detailed routing pro-cesses. Besides this, there are some problems in former global routers, for example, design time and cost, etc. This paper proposed a new algorithm in which pins ordering is considered to solve these problems. Using this algorithm, a global router is developed. Program experiments show the efficiency of the proposed algorithm.
