The purpose of this paper is to analyze the growth elasticity of the tourism industry in Kangwon Province. In order to understand the resent growth of this industry in Kangwon area author tried to define newly the concept of tourism industry, categolizing the several tourism industries more systematically. The results was found from the analysis that the growth elasticity of the tourism industry is higher growing industry than any other one, such as the mining and the manufacturing industry. The growth elasticity of the tourism industry from 1988 to 1990 was found 0.9, and from 1990 to 1992 it jumped to 3.23. This means that an increase of 1% per capita income in Kwangwon Province gaines also the value added per capita in the tourism industry from 0.9% in 1990 to 3.23% in 1992. Therefore the tourism industry contributes greatly to the expansion of income of that local people. In conclusion, author would suggest that not only the central & local goverment but the enterprises should encourage to invest more to the tourism industry than any other one, and to allot resources efficiently in the tourism industry.

As natural plant-based industry has been expanded, the use of oriental medicinal plants as cosmeceutical material received a lot of attentions in the cosmetic industry. This study was performed to investigate the ameliorating effect of cosmetic materials that bamboo shoots peel (BSP) or bamboo shoots flesh (BSF) extracts. After extraction of BSP or BSF, biological evaluation including anti-oxidative activity, anti-wrinkle, whitening effect, moisturizing effect was performed. As a result, among BSP and BSF, 5% ethanol extract of BSP exerted stronger scavenging activity against DPPH, ABTS and lipid peroxidation than others. In addition, total polyphenol and flavonoid contents of 5% ethanol extract of BSP was higher than that of BSF and other extracted BSP. This result indicates that extraction of BSP using 5% ethanol elevated anti-oxidative activity. Furthermore, the inhibitory effect of tyrosinase, elastase, and collagenase was evaluated by whitening and anti-wrinkle effect of 5% ethanol extracts of BSP. However, no statistically significant difference was observed in whitening and anti-wrinkle between 5% ethanol extract of BSP treated group and negative control group. On the other hand, in the moisture contents of BSP and skin moisturizing test, the 5% ethanol extracts of BSP showed higher moisturizing effect than the positive control group using 5% glycerin. These results suggest that the BSP extract is worthy of further investigation as a protective material for skin by oxidizing agents and dry condition.

본 연구는 구어(口語)적 이해력, 연속적인 기억력, 자기 통제력에 결함이 있는 자폐아동에게 연속적인 사진 단서(sequential photographic cues) 사용 방법을 중재함으로써 컴퓨터 사용 기술(computer literacy)의 하나인 컴퓨터 시작 및 종료하기 기술을 습득시켰다. 연구 대상은 일반 초등학교 시간제 특수학급에 입급되어 있는 저학년 자폐아동 3명이며 연구방법은 단일 대상 연구의 대상자간 중다간헐기초선 설계(multiple probe design across subjects)를 사용하였다. 연구의 기초선, 일반화, 유지 1 단계에서는 연구자의 중재 없이 사진 단서만을 제공하였으며 중재 단계에서는 연구자가 최소 촉진 전략을 사용하여 대상 아동에게 연속적인 사진 단서 사용 방법을 습득시키고 잘못된 반응을 교정하였다.또한 마지막으로 사진 단서를 소거한 조건에서 유지 2 검사를 실시하였다. 그 결과 연속적인 사진 단서 사용 중재는 자폐아동의 컴퓨터 시작하기 및 종료하기 기술을 습득, 일반화, 유지시켰으며 중재의 효과는 사진 단서를 완전히 소거한 조건에서도 유지되었다. 그러나 대상 아동 3은 컴퓨터 종료하기 기술을 수행 할 때에는 연속적인 사진 단서를 소거한 조건에서는 중재의 효과가 유지되지 못했다. 이러한 연구 결과는 연속적인 사진 단서 사용이 자폐아동의 연속적인 기억을 보조하는 중요한 단서임을 뒷받침하여 주고 있다. There have been growing concerns with computer education in our society for the past decade, following the recognition of the importance of computers as an essential means of getting information and of communication both in our everyday lives and in work places. These concerns and developments are equally applicable to the education of autistic children for whom the ultimate aim is community integration. However, computer education for autistic children also needs to consider their specific memory characteristics as well as their chronological age and their computer literacy level. Based on an experimental study, this dissertation explores whether sequential photographic cues might be an effective way to make autistic children perform the basic computer skills independently in an integrated classroom environment. Focusing on the task of logging on and off computers to use CD-ROMs, this study also discusses whether these skills generalises to other environments and other CD-ROMS, and whether the children could perform the same task successfully in delayed follow-up tests. we can conclude that sequential photographic cues used in structured instruction are an effective way of enabling autistic children to perform tasks independently.
