A decade has passed since the first generation of Genesis was launched in the U.S. with the plaque of Hyundai-Genesis. Genesis Motors was separated from Hyundai Motor in 2015, and has struggled to have the Genesis stand alone in the competitive U.S. luxury sedan market. The present case study aims to find challenges facing the Genesis, which Hyundai has positioned as a luxury sedan competing against conventional luxury brands such as BMW, Mercedes-Benz, and Lexus; evaluate Genesis Motors' strategic response to meet these challenges; and explore an alternative positioning strategy. Specifically, the present case study addresses barriers against the Genesis' market performance, by focusing on the obstacles rooted in the consumer perception as well as the obstacles that stem from the change in the U.S. automobile industry and the nascent network of the Genesis dealership. Genesis Motors' current strategies are evaluated, and an alternative strategy is explored that is largely based on the American consumers' perceptions of the Genesis vis-a-vis conventional luxury brands and outperforming midsize brands.

To understand the genesis of tropical cyclones (TC), we computed TC genesis probability (GPr) by partitioning a highly localized genesis frequency (GFq) into nearby grid boxes in proportion to the spatial coherence of genesis potential index (GPI). From the analysis of TCs simulated by the Seoul National University Atmosphere Model Version 0 and the observed TCs, it was shown that GPr reasonably converges to GFq when averaged over a long-term period in a decent grid size, supporting its validity as a proxy representing a true TC GPr. The composite anomalies of the gridded GPr in association with the Asia summer monsoon, El Nino-Southern Oscillation (ENSO), and the Madden-Julian Oscillation (MJO) are much less noisy than those of GFq, and consequently are better interpretable. In summary, GPr converges to GFq, varies more smoothly than GFq, represents the spatiotemporal variations of GFq better than GPI, and depicts GFq with greater spatial details than other spatially smoothed GFqs.

최근 전 세계적으로 지구온난화에 따른 기후변화로 태풍, 폭염, 폭설등과 같은 자연재해의 피해가 대규모로 확대되고 있다. 근본적으로 지구온난화를 유발하는 가장 큰 원인은 대기 중의 온실가스를 들 수 있으며, 온실가스의 농도 증가로 인해 우리나라가 속해있는 북반구는 점점 더 지구표면온도가 증가하고 있고, 그에 따른 극한 기상 발생률이 크게 증가하고 있다. 본 연구에서는 최근 이산화탄소 농도 추세를 반영한 RCP(Representative Concentration Pathway) 8.5 시나리오를 이용하여 미래의 태풍발생의 공간분포를 추정하였다. 공간분포를 추정하기 위해 먼저 RCP 8.5 월 자료를 사용하여 1982~2100년 기간 동안의 태풍발생지수(GPI; Genesis Potential Index)를 계산하였다. 1982~2010년 동안 발생한 태풍의 발생위치정보와 월평균 GPI 값을 이용하여 태풍발생의 확률분포(PDF)를 추정하였으며, PDF의 0.05, 0.1 및 0.15에 해당하는 GPI의 범위를 설정하여 0.05GPI, 0.1GPI 및 0.15GPI로 정의하였다. 이를 바탕으로 1982~2010년, 2011~2040년, 2041~2070년, 2071~2100년의 태풍발생의 공간 확률 분포를 추정 하였으며, 공간 확률 분포와 함께 과거 태풍발생정보를 이용하여 공간밀도를 분석하였다. 분석 결과, 미래에 태풍이 발생할 가능성이 높은 지역이 필리핀의 동쪽에 위치한 위도 $10^{\circ}{\sim}20^{\circ}$ 영역으로 나타났다. 이러한 결과를 통해 추후 미래의 태풍발생 가능지역을 추정하고, 이를 기반으로 태풍의 경로를 추정하는데 활용하여 태풍의 발생 위치에 따라 한반도에 미치는 영향을 추정하는데 활용할 수 있을 것으로 사료된다.

A probability prediction model for tropical cyclone (TC) genesis in the Northwestern Pacific area was developed using the logistic regression method. Total five predictors were used in this model: the lower-level relative vorticity, vertical wind shear, mid-level relative humidity, upper-level equivalent potential temperature, and sea surface temperature (SST). The values for four predictors except for SST were obtained from difference of spatial-averaged value between May and January, and the time average of Ni$\tilde{n}$o-3.4 index from February to April was used to see the SST effect. As a result of prediction for the TC genesis frequency from June to December during 1951 to 2007, the model was capable of predicting that 21 (22) years had higher (lower) frequency than the normal year. The analysis of real data indicated that the number of year with the higher (lower) frequency of TC genesis was 28 (29). The overall predictability was about 75%, and the model reliability was also verified statistically through the cross validation analysis method.

This paper describes recent development activities of the GENESIS code, which is a transport code for heterogeneous three-dimensional geometry, focusing on applications to reactor core analysis. For the treatment of anisotropic scattering, the concept of the simplified Pn method is introduced in order to reduce storage of flux moments. The accuracy of the present method is verified through a benchmark problem. Next, the iteration stability of the GENESIS code for the highly voided condition, which would appear in a severe accident (e.g., design extension) conditions, is discussed. The efficiencies of the coarse mesh finite difference and generalized coarse mesh rebalance acceleration methods are verified with various stabilization techniques. Use of the effective diffusion coefficient and the artificial grid diffusion coefficients are found to be effective to stabilize the acceleration calculation in highly voided conditions.

대기 및 해양의 대규모 환경에서 열대저기압 발생의 잠재적 빈도는 잠재생성지수(GPI; Genesis Potential Index)를 이용하여 예측할 수 있다. 본 연구에서는 18개의 CMIP5 기후모델을 이용하여 GPI의 연진동 및 경년변동성이 분석되었다. 비교를 위하여 재분석자료로부터 계산된 GPI의 연진동이 재조명되었다. 특히 CMIP5 기후모델과 재분석자료에 의한 GPI가 비교되었고, 그 차이에 대한 가능한 해석이 논의되었다. ENSO (El Nino and Southern Oscillation)는 열대 저기압 발생 및 경로에 영향을 주는 열대 기후현상이다. 잠재생성지수가 네 개의 대규모 매개변수의 함수임을 이용함으로써 열대저기압발생에 대한 역학적 해석이 제시되었다. 본 연구에서는 엘니뇨 혹은 라니냐 해에 GPI 편차를 논의하였고, 그 편차에 가장 영향을 많이 주는 인자를 찾았다. 또한 여러 대규모 인자를 활용하여 북태평양지역 열대저기압 발생에 대하여 가능한 기작을 논의하였다.

The myth reflects the human way of thinking about the world. Therefore, an important part of myth is human creation and role. This study examines the process of human creation in myth and discusses implications for education. The subjects that can be considered from the viewpoint of education are as follows. The status and role of teachers and students, the relationship between teachers and students, how to create or create humans, and the purpose and results of human creation. First, it is the position and role of the teacher. In myth, being like a teacher is a divine being that transcends human ability. In Dangun mythology, Hwanwoong or Shinwoong descended from heaven, and in the Genesis it is the Creator God. In Dangun mythology, the role of the teacher guides the way of becoming a human and provides necessary tasks. In Genesis, the image of the teacher is the Creator God. God plays the role of a teacher who prepares various environments in which learners can work. Second, the status and role of students in myths. In Dangun mythology, students are symbolized by bear and tiger. They go to the teacher with the desire to become human beings. In Dangun mythology, the student is not a passive existence but an autonomous and active image. In Genesis, the appearance of a student is a passive being created by a teacher. Third, the creation of human beings in myth can be seen in terms of educational process and method. In Dangun Myth, the beginning of education is the wish or expectation of learners. Learners eat mugwort and garlic and participate in human learning. In Genesis 1, however, there is no need for a special method, since human beings are created according to the Creator's command. Fourth, the purpose of education can be discussed through the purpose of human creation. In Dangun mythology, the purpose of education is not to live according to instinct but to become human with culture and personality. In Genesis 1, the purpose of human creation is the role of the Creator in creating and managing the world. Therefore, it is the aim of humans to manage the world in an orderly manner. The purpose of education in Genesis 2 is to enable humans to serve the world.
