With the continuous and outstanding development of information technology(IT), human being is coming to the new computing era which is called cloud computing. This era brings lots of huge benefits also at the same time release the resources of IT infrastructure and data boom for man. In the future no longer, most of IT service providers, enterprises, organizations and systems will adopt this new computing model. There are three main deployment models in cloud computing including public cloud, private cloud and hybrid cloud; each one also has its own cons and pros. While implementing any kind of cloud services, customers have to choose one of three above deployment models. Thus, our paper aims to represent a practical framework to help the adopter select which one will be the best suitable deployment model for their requirements by evaluating each model comprehensively. The framework is built by applying the analytic hierarchy process(AHP), namely benefit-cost-opportunity-risk(BCOR) model as a powerful and effective tool to serve the problem. The gained results hope not only to provide useful information for the readers but also to contribute valuable knowledge to this new area. In addition, it might support the practitioners' effective decision making process in case they meet the same issue and have a positive influence on the increase of right decision for the organization.

Among service industries of knowledge based economic era, the roles of educational service field are becoming more important and standard of educational service makes a direct effect on economic development and social growth. Therefore, accurate measurement of service quality is the most important assignment and the measurement of the service quality remains difficult assignment. So, this researcher classified quality attributes applying weighted value and found potential satisfaction level(PSL) and potential customer demand improvement index(PCDI) for trainees participating in national manpower business so as to suggest measurement of service quality and easiness of use and then, calculated satisfaction position and opportunity cost by quality factor with Taguchi's loss fraction. And, improvable satisfaction level was measured, opportunity cost by degree of customer dissatisfaction was quantitatively measured, and a model that can indicate with economic factors was suggested. In addition, methodology of measuring quality cost that can be reduced by quality improvement and direction of strategic decision-making for deciding items to be improved preferentially were suggested with qualitative index that can indicate the degree of customers' dissatisfaction by loss.

최근 정부는 제2 벤처 붐 확산을 위해 창업지원 프로그램을 확대하고 지원 규모도 늘리고 있다. 그러나 창업기업의 지속적인 성장을 위해서는 창업가가 갖추어야 할 기업가정신 교육이나 멘토링이 중요한 부분임에도 불구하고 정부 지원프로그램에 선정된 기업 중 일부에서는 사업화 자금만을 목적으로 하고 기업가정신 교육이나 멘토링 등의 프로그램 참여를 기피하는 현상이 나타나고 있는 실정이다. 본 연구는 정부 창업지원사업에 선정된 창업기업을 대상으로 제공되고 있는 멘토링의 내용과 횟수, 그리고 기업가적 기민성이 기회인지를 매개로 기업의 성과에 미치는 영향에 관해 연구함으로써 기업가적 기민성과 멘토링 프로그램의 중요성을 강조하고자 한다. 본 연구 실증분석에 따르면 첫째, 기업가적 기민성의 하위요인인 연합-연결력을 제외하고는 관찰-탐색력과 평가-판단력은 기회인지를 매개로 기업의 성과(재무, 비재무)에 영향을 미치는 것으로 나타났다. 둘째, 자금조달, 기술지원, 경영지원 멘토링은 기회인지를 매개로 기업의 재무 및 비재무성과에 영향을 주는 것으로 나타났다. 셋째, 멘토링 횟수 또한 기회인지를 매개로 기업의 재무, 비재무성과에 영향을 주는 것으로 나타났다. 본 연구의 시사점은 기업가적 기민성 하위요인 중 연합-연결력이 기회인지를 매개로 기업성과에 영향을 주지 않는 것으로 볼 때 프로그램 운영자들이 프로그램 설계와 운영시 창업자의 전략적 의사결정 기회를 침해하지 않는 방안에 대해 고려해야 한다는 것을 재점검해 볼 필요가 있다. 또한, 정부 창업지원 사업에서 창업기업에 제공되는 멘토링이 중요하다는 것이 실증적으로 규명된 만큼 각 창업기업의 성과목표에 맞는 맞춤형 멘토링이 필요하다는 것을 강조할 수 있다. 본 연구의 기여점은 기업가정신에 관한 연구에서 핵심 구성 요소로 다루어지고 있는 기업가적 기민성과 기회 인지, 그리고 실무적 측면에서 창업기업 성과에 중요한 요소로 인식되는 멘토링과 멘토링 횟수에 대한 요인들을 기업성과 영향 요인으로 이론적 실증적으로 규명하였다는 점이다. 아울러 멘토링을 지원하는 창업기업 지원 기관들에게 논리적 근거를 제시하였다는 것이다.

In the 21st century the service industry, particularly the hospitality industry, has the potential to develop into its golden age. In preparation for this hotels must maximize management proficiency by introducing reasonable and scientific systems into their current operations. The hotel industry takes it for granted that it can meet the final business goal by way of effective management of human resources. However, comprehensive papers on the subject of employee satisfaction have not appeared or been presented in Korean business studies. And although papers from abroad have touched on the subject they are not focused on the specialized domain of human resources as it applies to the comprehensive matters relating to job satisfaction as a corelationship to business success. This study focuses on some problems that must be overcome in achieving business objectives while striving at the same time to maintain satisfaction. The purpose of this study is to find the factors that measure employee job satisfaction in the hotel industry. To establish the purpose I reviewed the definition of the job satisfaction. An antecedent study of job satisfaction and Questionnaires were used to acquire data, specifically, hotel employees were selected randomly from the six super-deluxe hotels in Seoul to respond to thorough questionnaires. As a result of the study on the variables of Sex, Position, Length of Service, Opportunity for Promotion, Working Conditions, Wages and Hotel Situation. As a whole, promotional opportunity, wages and working conditions were frequently cited as negative factors in the responses. A comprehensive approach that includes improving wages and that reflects management's sincere concern with the working conditions of the employees is urgently needed. Hotel management that is willing to examine employee satisfaction periodically and provide proper solutions can prevent dissatisfied employees from separating from their jobs. This study has some limitation in that it is restricted geographically and in research method. That is, only six super-deluxe hotels in Seoul were selected as the subject of study and only the questionnaire method of obtaining data was used out of various available research methods.

The purpose of the study was to investigate the influences of contract foodservice managers' personal characteristics, foodservice characteristics and organizational characteristics on job satisfaction, including interpersonal relationships, self-actualization and promotion opportunity categories. A survey was administered to four hundred contract foodservice managers of five large companies and five small/medium companies in the Seoul and Kyungin areas. The final response rate was 66%(N=265), and the data were analyzed using SPSS Windows(ver. 12.0). The respondents were 76.1% female, average age 28.8 years, and 73.0% were regular workers. Contract foodservices have profit and loss contracts(69.1%), single menu types(59.6%) and buffet serving styles(37.7%). There are significant differences of job satisfaction by some personal characteristic variables(gender, martial status, age, education, position, work hours, period of working for the present company, and payroll per year) and foodservice characteristic variables(type of contract and charge of food costs). In three job satisfaction categories, foodservice managers reported the highest interpersonal relationship satisfaction, following self-actualization satisfaction and promotion opportunity satisfaction in both large companies and small/medium companies. However, foodservice managers of large companies tended to be more satisfied regarding their promotion opportunities than foodservice managers of small/medium companies(p<0.05). Work hours, number of meals served/day, male, workload, communication with the clients, relationship with co-workers, obvious role and autonomy were significant factors to increase the job satisfaction in contract foodservices of large companies. On the other hand, relationships with co-workers and males were significant factors to increase the job satisfaction in contract foodservices of small/medium companies. This research suggests that contract foodservice companies need to understand the characteristics of their managers, foodservices and organizations to enhance the job satisfaction of foodservice managers and to develop specified human resource management strategies that can be applied to each company scale.

Universal soil loss equation (USLE) is used to estimate soil loss solely or employed in any hydrologic models. Since soil erosion has been an issue in South Korea for decades, the Ministry of Environment enacted a law to regulate soil erosion in 2012, which is the Notification of topsoil erosion status. The notification is composed of preliminary and field investigations, the preliminary investigation suggests to use USLE and provides USLE factors. However, the USLE factors provided in the notification was prepared at least 10 years ago, therefore it is limited to reflect recent climate changes. Moreover the current yearly USLE approach does not provide an opportunity to consider seasonal variation of soil erosion in South Korea. A GIS-based model was therefore applied to evaluate the yearly USLE approach in the notification. The GIS-based model employs USLE to estimate soil loss, providing an opportunity to estimate monthly soil loss with monthly USLE factor databases. Soil loss was compared in five watersheds, which were Geumgang, Hangang, Nakdonggang, Seomjingang, and Yeongsangang watersheds. The minimum difference was found at Seomjingang watershed, the yearly potential soil loss were 40.15 Mg/ha/yr by the notification approach and 34.42 Mg/ha/yr by the GIS-based model using monthly approach. And, the maximum difference was found at Nakdonggang watershed, the yearly potential soil loss were 27.01 Mg/ha/yr by the notification approach and 10.67 Mg/ha/yr by the GIS-based model using monthly approach. As a part of the study result, it was found that the potential soil loss can be overestimated in the notification approach.
