While the international construction industry for Korean companies have grown in market size exponentially in the recent years, the profit rate of small and medium sized construction companies (SMCCs) are incomparably lower than those of large construction companies. Furthermore, small and medium size companies, especially subcontractor, lacks the judgement of project involvement appropriateness, which leads to an unpredictable profit rate. Therefore, this research aims to create a profit rate prediction model for the international construction project focusing on SMCCs. First, the factors that influence the profit rate and the area of profit zone are defined by using a total of 8,637 projects since the year 1965. Seconds, an extensive literature review is conducted to derive 10 influencing factors. Multiple regression analysis and corresponding judgement technique are used to derive the weight of each factor. Third, cased based reasoning (CBR) methodology is applied to develop the model for profit rate analysis in the project participation review stage. Using 120 validation data set, the developed model showed 11% (14 data sets) of error rate for type 1 and type 2 error. In utilizing the result, project decision makers are able to make decision based on authentic results instead of intuitive based decisions. The model additionally give guidance to the Korean subcontractors when advancing into the international construction based on the model result that shows the profit distribution and checks in advance for the quality of the project to secure a sound profit in each project.

세계적으로 마이크로그리드에 이목이 집중되고 있는 현재 상황에서 DER(Distributed Energy Resources : 분산형 독립전원)의 역할이 대두되고 있다. 캠퍼스 마이크로그리드는 대학교의 캠퍼스를 하나이상의 DER로 선정하여 피크 시 교내 전기수요의 일부분을 해소할 수 있는 전력망 기반의 네트워크 시스템이다. 해외에서는 이미 캠퍼스 마이크로그리드 성공사례를 보여주었고, 이후 많은 캠퍼스에서 캠퍼스 마이크로그리드를 벤치마킹하고 있다. 본 논문에서는 캠퍼스 마이크로그리드에 필요한 DER을 구성하기 전 캠퍼스 내의 건물별, 계절별 전력수요 특성을 분석하고자 한다.

정보통신부는 2003년 7월 통신시장의 유효경쟁 활성화 방안으로 기존의 설비기반경쟁보다는 서비스 기반경쟁을 지향하겠다는 입장을 표명하였다. 고정망의 경우 서비스기반 경쟁을 위한 규제적 장치가 많은 반면 이동망의 경우 경쟁방안이 부재한 상태이다. 이에 따라 해외 많은 나라에서는 서비스 기반 경쟁 활성화를 위한 대안들을 모색하고 있다. 따라서 본 고에서는 설비기반 경쟁과 서비스 기반 경쟁의 개념 및 사례들을 분석하고 이를 통해 서비스기반 경쟁을 활성화시킬 방안을 제시하고자 한다.

The number of foreign applications available in Korea is increasing. Among them, there are many cases where applications having a large number of domestic users collect users' personal information in an unauthorized manner, causing serious problems. Unauthorized collection of personal information conducted through such applications is highly dangerous, because sensitive personal information of users can be used in a malicious way. Further, this is violation of business ethics and may interrupt the creation of the sound information technology ecosystem. This research is purposed to analyze the current status of unauthorized collection of users' personal information by foreign applications available in Korea and to derive countermeasures thereof.

Risk management is an important element for successful management of overseas construction projects. This study reports a case study in which we proposed a risk management planning and procedure for plant construction which can be applied throughout the project life cycle. We analyzed the risk management practices of Korean construction companies by applying the concept of the PRINCE2 method developed in the UK, and proposed a risk management planning and procedure with organizational structure and working process. The suggested risk management planning and procedure was applied to an overseas plant construction project, and produced good results. It is believed that the procedure suggested here can also be aplied to other companies to enhance the competency in the global construction market.

A main purpose of this research is to identify success factors of start-up based on the AER case study. As a result of case analysis, In the early stage, the success factors of start-up are the entrepreneur's history, experience, expertise, prompt judgment, problem-solving ability, the capacity and teamwork of its members, business networks and supporting government start-ups. In the commercialization stage, securing commercialization and investment funds, timing, differentiation strategy, overseas advancement, and acceptance of customer feedback are important. In the growth stage (maturity stage), new product launches and diversification, and establishment of organizational culture are important. Based on the results of this analysis, this study sought success factors and implications for each stage and sought research directions in the future.

WorldJob+, being operated by The Human Resources Development Service of Korea, provides a recruitment support services to overseas companies wanting to hire talented Korean applicants and interns, and support the entire course from overseas advancement information check to enrollment, interview, and learning for young job-seekers. More than 300,000 young people have registered in WorldJob+, an overseas united information network, for job placement. To innovate WorldJob+'s services for young job-seekers, Splunk, a powerful platform for analyzing machine data, was introduced to collate and view system log files collected from its website. Leveraging Splunk's built-in data visualization and analytical features, WorldJob+ has built custom tools to gain insight into the operation of the recruitment supporting service system and to increase its integrity. Use cases include descriptive and predictive analytics for matching up services to allow employers and job seekers to be matched based on their respective needs and profiles, and connect jobseekers with the best recruiters and employers on the market, helping job seekers secure the best jobs fast. This paper will cover the numerous ways WorldJob+ has leveraged Splunk to improve its recruitment supporting services.

Recently, the market size of the global electronic-commerce is rapidly growing. The global market size of an overseas direct-purchase is expected to reach 1 trillion won by 2020. This study intends to determine the decision making factors of B2B overseas direct-purchase(DP) and reverse direct-purchase(RDP), and the impact on the vitalization of the small to middle-sized companies'(SMC) overseas DP and RDP. Ultimately, the purpose of this study is to provide a policy insight on the expansion of exports by SMC. For this, we determined the necessary elements for getting good results by Korean SCM in the overseas DP and RDP market through a preceding research based on resource-based theory and industry structure theory. Afterwards, we used the multiple regression model for positive analysis of the survey documents. We were able to confirm through analysis that the company information, logistics delivery, customs process, law and regulations have positive effects on the overseas DP and RDP. This study surveyed the entire overseas DP market, rather than focusing on the cases of harm and responses of the overseas DP, which was the topic for the preceding research, and can be differentiated from the previous study by deducting influence factors for the Korean SMC to succeed in the overseas DP and RDP market. Moreover, the results of this study is meaningful in proposing a strategic direction for the SMC participating in the overseas DP market and the government enacting policies.

Propaganda is often accepted as the political promotion that had used mostly by the socialist states during the First and the Second World Wars and the Cold War and by Hitler who governed Germany. Therefore, cases of the study on the image and picture propaganda were mostly posters or films of the socialism period when the propaganda was active. However, today it is not easy any more to find propaganda of the clear promotion characteristic as the past. In these modern times, it has changed into metaphorical propaganda based on 'persuasion', rather than publicity like past. Therefore, it has been changing from the direct promotion of the past into the indirect persuasion; and from the raw, direct and powerful publicity and claim into the soft and metaphorical persuasion and appeal. Thus, investigating again the contemporary propaganda will be an important element in analyzing contemporary images. The animation, selected as a target of the analysis of propaganda, exists in various ways in various images of the modern times, which is not too much to say that today's society is the television society. Besides, the animation is the image that can cover all ages as men and women of all ages can watch, so it is proper for analysis of the contemporary propaganda of metaphorical, indirect and various forms.
