This paper was conducted to study the conditions for the manufacture and operation of artificial snow removal and ice-making test facilities so that the test equipment can be tested in a low-temperature environment using the polar environment performance test facility. The polar environment performance test Facility is designed to artificially simulate extreme environments up to -65 ℃, and is a mid-to-large low-temperature environment test facility that can perform performance tests on offshore plant equipment, ships, leisure, and offshore structures. To verify the safety of deck work of ships operating in polar environments, artificial snow removal and artificial ice making devices were manufactured, and we conducted research on various operating environments using these facilities. For the efficient operation of artificial snow and ice making facilities, it is important to continuously supply dry air, and it has been found that installing an additional heater at the tip of the nozzle is effective in preventing freezing.

We have designed and fabricated computer generated holograms(CGH) to generate ashepheric wavefront and Bessel beam. Designed CGH is recorded onto the photopolymer which is used as a volume hologram material mating CGHOE(computer generated holographic optical element). To investigate properties of fabricated CGHOE, intensities of Bessel beam are measured as a function of propagation(z-axis) and transverse (x-axis) distances.

The Finite element methods have been applied to various problems of interest, as witnessed by the extensive literature currently available. Transient linear elasto-dynamic problems are solved in a time domain by the FEM, for which the finite element equations are derived from the weak formulation based on the differential equations of motion using a stable time integration scheme known as the Newmark method, where the dependent variables are semidiscretized in series of the products of the spatial and temporal functions. The wave propagation problems by two and three dimensional and axisymetric models are analyzed to show the versatility of the presented formulation, resulting in good and stable numerical results.

This paper aims to provide an adequate theoretical interpretation of the South Korean government’s North Korea policy led by Kim Dae Jung with a particular focus on his attempts to promote inter-Korean trade under political hostility. It finds the so-called ‘Jŏngkyŏng Bulli’ initiative and permission of inter-Korean contact through multiple channels as key elements that facilitated uninterrupted growth of trade between the two Koreas while the military confrontation still prevailed. As a preliminary analytical framework to explain the substantial changes in inter-Korean relations during the Kim Dae Jung presidency, this paper proposes complex interdependence model as an ideal type of relationship. The model reflects a key pattern of changes in international relations, typified by transnational interaction and asymmetrical reciprocity, and these notions also create a backdrop that generated the Kim Dae Jung policy in establishing improved economic exchanges with the DPRK.

In this study, a study was conducted to analyze the factors affecting the acceptability for autonomous vehicles. The previous studies were reviewed to sturdy the acceptance factors and The PLS Structral equation model was used to analyze the acceptance factors. While the existing research focused on technical safety, this study comprehensively analyze safety, convenience, economy, environment, and ethical factors. The PLS model was analyzed to significant the factors that affect the acceptability for autonomous vehicles in the order of safety, economy, convenience and environment. 본 연구에서는 자율주행자동차의 수용성에 미치는 주요 요인들을 분석하고자 하였다. 본연구에서는 우리나라 정서에 맞는 수용 요인들을 분석하기 위해서 자율주행자동차 수용성에대한 기존 선행 연구들을 분석하였고 PLS-구조방정식 모형을 중심으로 요인분석 연구를 진행하였다. 기존 연구에서는 기술수용모델에 의한 기술적인 안전성 연구에 중점을 두었다면, 본연구는 우리나라 자율주행자동차 수용성에 대하여 새로운 시각으로 안전성 뿐만 아니라 편의성, 경제성, 환경성, 윤리성 요인등을 동시에 종합분석 하였다. 분석결과, 자율주행자동차의 수용성에 미치는 잠재요인은 안전성, 경제성, 편의성, 환경성 순으로 중요도가 분석되었다.
