This study is designed to investigate the types and characteristics of opinion leadership in Korean golf market. Sport is one of service products, which shows rapid growth of its market size and importance in a national economy. Due to its differential features against goods, service, including sports as one of entertainment sectors needs more for opinion leader's role in diffusion into the market under communication environments. Grounded on the two-staged measurement, a new approach to the trichotomous classification(opinion leaders, opinion accepters, and opinion neutrals) was proposed and empirically tested via 500 samples of Seoul area residents as of April 2002. At the first stage, total consumers were divided into two groups based on the degree of involvement plus interest with golf. Second stage classified high involved group into opinion leaders(influencers) and opinion accepters(influencees). Results of the comparison with characteristics among three groups show more clear and exclusive features of opinion leadership under the diffusion processes of innovation. Moreover, outsiders called as opinion neutrals was found to be indifferent to the object(golf) in the communication processes in the market. Findings of this study can be applied to marketing practices in Korean golf industry and at the same time are likely to contribute for the studies followed on sports promotional strategies.

토석류는 강우로 인해 토사와 물이 섞여 산지 아래의 유하부까지 흘러내리는 현상으로 많은 인명과 재산피해를 유발한다. 우리나라에서 발생된 대부분의 토석류는 집중강우 시 얕은 사면파괴가 발생된 지점에서 계곡부를 따라 토석류로 전이되었다. 따라서 토석류 위험에 대응하기 위해서는 우선적으로 토석류 발생 위치를 정확히 식별해야 한다. 본 연구에서는 2011년에 많은 피해가 발생했던 서울 우면산을 대상으로 지형학적 특성과 물리 기반 모델을 결합하여 토석류가 발생할 수 있는 위치를 예측하는 방법을 제안하였다. 우선 국내⋅외 토석류 발생 위치의 지형학적 특성을 기반으로 연구대상 지역의 지형학적 특성을 구축하였다. 그리고 물리 기반 모델과 당시의 누적강우량 자료를 활용하여 안전율 지도를 제작하였다. 최종적으로 토석류 지형학적 특성과 안전율이 1.2 이하인 곳이 중첩되는 셀을 추출함으로서 토석류 발생원 예측 기법을 개발하였다. 정량지수분석을 통해 검증을 수행한 결과 본 연구에서 제안한 토석류 발생원 예측 기법의 순 성공지수가 가장 높은 것으로 나타났다. 이와 같은 연구를 통해 토석류의 발생 위치를 보다 정확히 예측할 수 있을 것으로 기대된다. A debris flow is a phenomenon in which sediment matter and water become mixed and flow down to a deposition area, thereby causing significant damage to people and property. In Korea, majority of the past debris flows initiated in the form of shallow landslides during rainfall. To address the hazards associated with debris flows, it is necessary to establish a method for predicting the location of the debris flow initiation. In this study, we propose a method for predicting the source of a debris flow by incorporating geomorphological characteristics and designing a physically-based model. The geomorphological characteristics associated with the initiation area of the debris flow were determined by analyzing previous literature. The physically-based model was developed by incorporating landslide inventory data, rainfall data, and geotechnical characteristics, and the map of safety factor less than 1.2 was thereby established. Furthermore, the region prone to the occurrence of debris flows was identified by the superposition of each unstable pixel obtained from the geomorphological characteristics and the physically-based model. The proposed method was validated through quantitative index analysis. The obtained results indicate that compared to other methods, the proposed method has a high success index and a low error index for predicting the source of a debris flow.

솔 벨로우의 『비의 왕 헨더슨』에 나타난 아담상

송창호(Song, Chang-Ho) 신영어영문학회 2016 신영어영문학 Vol.65 No.-

This paper examines to analyze American Adam imagery in Saul Bellow’s Henderson the Rain King. Henderson has suffered from his troubled life in the society, and he wants to escape from the affairs of this transient life rather than to confront his dilemmas. He envisions a new paradise like Adam. However, this paradise often proves to be illusory, offering no real comfort for his traumas. After experiencing many adventures with two tribes in Africa to find meaningful life, Henderson willingly hopes to meet his wife and even the persons who he has not liked. As an active and positive person, Henderson clearly realizes that man can not escape life and that man must learn to cope with his dilemmas, adapting to the world. Consequently, this novel can be evaluated to be the best positive one in Bellow’s works.
