With recent rise inmedico-legal problems, there is also an increase in number of problems involved with anesthesia. Major cause of anesthetic accident are malfunctioning anesthetic machine and inappropriate gas flow and concentration of anesthetic gas, resulting from maifunctioning ventilatory circuit. Therefore, anesthesiologist needs an apparatus to determine the appropriateness of ventilation and a monitoring system to measure a concentration of inspired O_2 and inhalation anesthetics. To prevent circulatory and respiratory abnormalities and promote the safty during anesthesia, we used the SARA monitoring system, as an indicator of safty measure. We monitored the anesthesia machines (n=17), using in operating room in Shinchon Severance hospital, by using the SARA monitoring system, as an indicator of safty measure. We intended to analysis the relationships between anesthetic machines, vaporizers, ventilators and parameters measured form each machine, in clinical use. The results were as follows; 1) Average used year of anesthesia machines was 7.7 years, that of vaporizers was 7.6 years and that of ventilators was 4.0 years. 2) When vaporizer's dial was fixed at enflurane 2.0%, average measured0Fi'Enf was 2.02±%, equal to dial setting and average Fi'Enf was 1.70±25%, usually lower than dial setting. 3) In some anesthesia machines, CO_2 revreathing occured always during ansthesia and Fi'Enf & FeEnf were decreased in case of CO_2 revreathing. 4) Fi'Enf by vaporizers was decreased as following orders, Draeger, Ohio and Cyprene.

This study investigates the facility use status of smart farming farmers to improve facility use rate of farmers. To this end, a survey was conducted on smart farming farmers in Jeonnam province, and the main survey contents are as follows: facility use rate, the reasons for low facility use, the perception of the introduction and use of smart farming etc. As a result of the survey, many farmers have introduced smart farming facilities even though they do not have enough use capacity. Thus it is necessary to improve the use capacity of farmers. Second, the average facility use rate of farmers was 65.1%, and 37.5% of respondents did not use even 50% of smart farming facilities. To improve the use rate, education on how to use facilities and continuous consulting support for farmers are needed. And the largest number of farmers perceived the risk like crop damage or facility failure due to poor use of facilities. This means that risk management due to the smart farming facilities is important. Third, farmers answered that rapid and continuous repair service were the most important when using facilities. Thus it is important to foster rear industries such as maintenance companies to stably operate smart farming facilities.

This study suggests the yield forecast models for autumn chinese cabbage and radish using crop growth and development information. For this, we construct 24 alternative yield forecast models and compare the predictive power using root mean square percentage errors. The results shows that the predictive power of model including crop growth and development informations is better than model which does not include those informations. But the forecast errors of best forecast models exceeds 5%. Thus it is important to establish reliable data and improve forecast models.
A Study on Laver Industry’s Global Export Competitiveness
이춘수 한국무역보험학회 2018 무역보험연구 Vol.19 No.4
In 2017, laver exports claimed the top spot previously held by tuna exports. laver is an important item that can create K-Food food culture in addition to Korean Wave of K-POP. Recently, demand for laver in countries including China, Japan, and Thailand have been steadily increasing. Despite various political situations, China has steadily increased demand for Korean laver. Thailand is contributing to the export growth of Korean laver, because of the trend of new Korean Wave mainly in laver snacks. The propose of this study is to review international marketing plan for Korean laver to have global export competitiveness. First of all, literature on laver industry is reviewed and current trends of laver industry in China, Japan and Thailand is explained. Segmentation strategy, Targeting strategy, Positioning strategy. as well as strategies for Product, Price, Place, and Promotion strategies are presented. Through the STP strategy and the 4P strategy of this study, SWOT analysis for the laver industry was conducted. Through the analysis, various ways of enhancing export competitiveness of laver industry in Korea is suggested. In particular, international marketing strategy of laver industry and future strategic measures are suggested.
독립국가연합(CIS) 시장에서의 한국제품 평가 개선에 관한 연구:신흥시장 개척 및 확대 관점에서
이춘수,이장로,신소현 한국국제경영관리학회 2007 국제경영리뷰 Vol.11 No.3
본 연구의 목적을 요약하면 다음과 같다. 첫째, 전략적으로 매우 중요한 위치인 독립연합국가(CIS) 지역의 신흥시장 확대를 위해 해당지역의 소비자들에게 한국제품평가에 대한 실증분석 실시하였다. 이를 통하여 한국경제이미지, 한국비경제이미지 및 한국기업이미지가 어떠한 영향을 미치는지 파악하였다. 둘째, 브랜드구매경험, 원산지파악유무, 한국지식 등의 더미변수는 소비자의 제품평가에 어떠한 영향을 미치는지 실증하였다. 셋째, 이러한 실증분석의 결과를 바탕으로 정부와 기업이 CIS시장에 성공적으로 시장 진출 및 확대를 할 수 있는 실행방안에 대하여 논의하였다. 본 연구는 가설검증결과를 통하여 CIS 지역의 신흥시장 개척과 확대 방안을 위한 실증적 근거를 제시하였다는데 있다. CIS 소비자에 대한 한국제품의 평가를 개선하기 위해서는 한국의 경제적 이미지를 중점적으로 부각하는 것이 중요하다. 또한 소비자의 제품평가에 유의하게 영향을 미치고 있는 한국기업이미지를 중점적으로 부각하여 파급효과를 제고할 필요성이 있다고 판단된다. The aims of the study are down specified. Firstly, through an empirical study we assessed the consumers' evaluation toward Korean products in CIS market, where is strategically important to Korea and Korean organizations searching a growth opportunity overseas. Understanding of impact of the three important aspects, Korean economy image, Korean non-economy image, and Korean corporate image, has been obtained. Secondly, How consumers' specific three aspects, consumers' purchase experience of Korean brands, their level of knowledge of Korea, and whether they check products' country of origin, impact on the consumers' evaluation toward Korean products has been examined. Lastly, based upon the results, strategic blueprints to develop and expand the CIS market have been proposed. As the results cited, Korean economy image and Korean corporate image influence Korean product evaluation in CIS market. Therefore those two aspects are recommended to focus more to promote. However, the impact of Korean non-economy image on Korean product evaluation is not supported statistically, so the formation of Korean non-economy image is advised through promotion of cross-cultural exchanges and personal interchanges.
