A Study on Situation of Management of Korean Tourists Hotels
Kim, Joung Keun(金正根) 세계문화관광학회 2008 Conference Proceedings Vol.9 No.0
Purpose of this study is to understand present situation of management of Korean tourists hotels of last 22years, to figure out its problems, and to suggest plan for improvement. This study was conducted on 580 Korean tourist hotels, based on trends of their sales revenue and the number of guests during the 22years; from 1985 to 2006. Data were collected from "Performances of Tourists Hotel Operations", which is annually published by KHA - Korea Hotel Association. Results of the study are as followings. First, supply and demand for hotels are concentrated to 5-star hotels in Seoul, and local tourists hotels are suffering from their low performance. Therefore, those local tourists hotels should be turned into mid - fare hotels and chain system, to be re-vitalized. Second, the level of provided service should be modified to be matched to its price level. To achieve this goal, education and training are needed to improve level of employees. Third, the government should recognize and support tourist hotels. Support proportion to export industries and formation of infrastructure are needed.

본 연구는 D. spatulata sp. Tokaiensis의 기내증식체계를 확립하기 위해 배지의 농도, 배지내 활성탄 및 당의 농도가 엽절편 배양 시 식물체 재분화에 미치는 영향을 알아보고자 실시하였다. 엽절편의 생존율은 명배양보다 암배양에서 더 높게 나타났으며, 배지의 농도가 낮을수록 생존율이 높았다. 각 절편당 신초형성수, 신초길이, 신초중 및 근생장은 1/4MS배지의 농도에서 높은 경향이었으며, 광조건에 따른 차이는 유의성이 없었다. 활성탄 농도에 따른 생존율은 1/2MS와 1MS 배지에서보다 1/4MS배지에서 높게 나타났으나, 통계적 차이는 보이지 않았다. 절편체당 뿌리의 형성수는 대부분 배지농도에서 30g L⁻¹ 당을 첨가한 배지에서 높게 나타났다. 1/2MS, 1/4MS에서 당의 농도가 높을수록 신초와 뿌리의 형성수가 증가하는 경향을 보였다. 따라서 끈끈이주걱의 엽절편배양시 증식효율을 높이기 위해서는 1/4MS배지에 당 30g L⁻¹이 첨가된 배지에 배양하는 것이 좋은 것으로 나타났다. In order to establish in vitro propagation of sundew, Drosera spatulata sp. Tokaiensis, the effect of MS medium, sucrose, activated charcoal concentration on shoot proliferation and root formation were investigated using leaves at 6 months after seed germination. Survival rates of leaf explants were higher in dark condition than light condition and as low as lower MS medium strength. Shoot and root growth were better in quarter strength of MS medium than that of other MS media, but were not different significantly according to light condition. Survival rate accroding to activated charcoal concentration was higher in 1/4 MS medium than those of 1/2 MS and 1 MS media, but was not different significantly. In the whole treatments, the optimum sucrose concentration for shoot proliferation was over 30 g L⁻¹. Therefore, to increase the proliferation efficiency through leaf culture of sundew, it might be cultured in quarter strength of MS medium with 30 g L⁻¹ sucrose.
