This article reviews the current issues of engineering education: engineering creativity, R&D 3.0 and Education 3.0 and comfirms need of refining quality of engineering education through learner-centered hybrid project learning. this article suggests the Global engineering project(GEP) program as an ideal hybrid project learning model that develop student's creativity and convergence capability. GEP program is learnner-centered interdisciplinary program that whole processes are managed by interdisciplinary students team aiming to global engineers who are globally competent and locally relevant so that they can function effectively in any country by local activity in developing country. The program consist of four main parts: 1)pre activity, 2)local activity from abroad, 3)design and producing prototype and 4)participating in the design contest or academic conference with the products. As a result, students' global competence, teamwork skill and capability of creative problem solving are remarkably improved.

According to Electronic Times(2012. 1. 3), "PMO was introduced from 1950s in the USA and as of 2010, PMO participated in 84% of project ordered by public and private sector." And Ministry of public administration and security announced that the Ministry will organize Task Force for arranging "standard for introduction and operation of PMO" for support of project implementation and strengthening specialty of ordering organization, and then, actively launch the Task Force from February, 2012. Thus, necessity of PMO is regarded as natural in some aspect but thesis for doctoral degree written by Kim Gi-yeong(2007) suggested, "performance of several projects begun at the same time cannot be interpreted as high according to whether PMO team exists or not." Martin et al.(2005) asserted, "according to whether PMO team exists or not, but there is no significant difference in other factor." In the contradictory situation, it is necessary to perform more various approaches for performance and necessity of PMO in the academic aspect.

Global Positioning System(hereafter; GPS) is recently an essential element in the various navigation and weapon delivery systems of military aircraft. However, GPS is vulnerable to the jamming threats since its signal power is very weak. Therefore, ROK defense has been concerning how to resolve this issue and how to integrate these systems needed, and is trying to acquire the proper anti-jamming GPS system. This study is to provide several schemes against the jamming threats effectively. We propose the several processes to analyze the required capability and demonstrate the result's of modeling and simulations(hereafter; M&S) for this integration of military aircraft, and the mathematical programming model for system optimization of military aircraft anti-jamming GPS system on the basis analysis of M&S results which could be considered available budget and the project characteristic. These schemes will be helpful on proper acquisition of these systems and. We are looking forward to contributing to the integration of anti-jamming GPS system of ROK military aircraft.

While software globalization is becoming more important, little research has been undertaken into what is meant by globalization and the degree of globalization capability in the Korean software industry. A survey study was conducted among software engineering professionals, gathering the data from 31 IT companies across 7 large-scale projects in Korea. The results indicate that the evaluation score for globalization capability is 2.51 out of 5 points, which is the lowest compared to other areas of software engineering such as team capability (2.88), process and tool supports (2.96), project management (2.97) and development (3.64). We also discuss how to introduce software globalization technologies in Korea based on the successful experiences of leading global IT companies.

The evaluation of dredging works of pump dredger considering soil conditions is a main idea in calculating construction costs in non-cohesive soil layers. For using pump dredger, on effects of pump dredger equipment, some data of overseas code for pump dredger are different to those of results and a pump dredging capability table in the field of costs. In this study, considerations of sandy soils are described for application of construction works.

현재 IT서비스 업체에서 새로운 성장동력으로 떠오르고 있는 분야가 융복합사업(IT+IT, IT+장비, IT+장비+시공)이라고 불리우는 컨버전스 프로젝트이다. 기존의 IT분야의 프로젝트와는 전혀 다른 특성을 갖고 있는 컨버전스 프로젝트에 대한 IT서비스 업체의 준비는 아직 미흡한 것이 현실이다. LG CNS에서는 이런 현실에서 컨버전스 프로젝트의 특성에 맞추어 기존 프로젝트 관리자(Project Manager)의 역할을 재정의하고 이를 현장에 적용시키기 위해 그동안의 컨버전스 프로젝트를 수행하면서 얻은 이슈에 HPT(Human Performance Technology; 수행공학)를 적용하여 조직적인 차원에서 프로젝트 관리자의 육성 로드맵을 만들고 이를 확산시키는 활동을 진행하고 있다. 이에 본 발표에서는 HPT측면에서 컨버전스 프로젝트 이행역량을 강화하기 위한 사례를 소개하고자 한다.

We propose an efficient information science teaching-learning method to improve information-scientific creativity of mathematically and scientifically gifted students. The students are able to improve their creative problem solving and team-work abilities through team project work to resolve a variety of application problem in real world. In the pursuit of this purpose, we designed a new two-stage information science learning method consisted of the standard stage and the application stage, and a new systemic project process. Moreover, we applied small-scale cooperation learning strategies and a multi-dimensional assessment system. The analysis on our proposed model shows that there is a remarkable achievement of educational objectives on cognitive capability, social and affective ability of information science creativity.

A convenient algorithm for optimizing wavelength selection in multiple linear regression (MLR) has been developed. MOP (MLP Optimization Program) has been developed to test all possible MLR calibration models in a given spectral range and finally find an optimal MLR model with external validation capability. MOP generates all calibration models from all possible combinations of wavelength, and simultaneously calculates SEC (Standard Error of Calibration) and SEV (Standard Error of Validation) by predicting samples in a validation data set. Finally, with determined SEC and SEV, it calculates another parameter called SAD (Sum of SEC, SEV, and Absolute Difference between SEC and SEV: sum(SEC+SEV+Abs(SEC-SEV)). SAD is an useful parameter to find an optimal calibration model without over-fitting by simultaneously evaluating SEC, SEV, and difference of error between calibration and validation. The calibration model corresponding to the smallest SAD value is chosen as an optimum because the errors in both calibration and validation are minimal as well as similar in scale. To evaluate the capability of MOP, the determination of benzene content in unleaded gasoline has been examined. MOP successfully found the optimal calibration model and showed the better calibration and independent prediction performance compared to conventional MLR calibration.

The SPICA (SPace Infrared Telescope for Cosmology & Astrophysics) project is a next-generation infrared space telescope optimized for mid- and far-infrared observation with a cryogenically cooled 3m-class telescope. Owing to unique capability of focal plane instruments onboard SPICA, it will enable us to resolve many astronomical key issues from the star-formation history of the universe to the planetary formation. The FPC (Focal Plane Camera) is a Korean-led near-infrared instrument as an international collaboration. Korean consortium for FPC proposed a key instrument responsible for a fine guiding (FPC-G). The back-up of FPC-G will make scientific observations as well. We have examined the legacy science programs for FPC and performed the feasibility study for the fine guiding system. Recently, the international review process is now in progress, in order to make a selection of the focal plane instruments. Here, we report the current status of SPICA/FPC project.

Recently, creative innovation has become a major topic in management innovation and due to this, various researches on its need and methodologies are being performed. According to previous studies on ambidexterity, explorative innovation is closer to divergent and right-sided brain, while exploitative innovation is closer to convergent and left-sided brain. Topic was to identify preceding element which affects Ambidextrous Innovation. For this topic, 129 Six Sigma projects from 19 different companies were collected. Ambidextrous index from preceding studies was used. This index represents the degree of ambidextrous activation and can be calculated by multiplying cumulative usage of exploitative tools with that of explorative tools. In the project characteristics, simple linear regression result showed leadership degree, team's vitalization degree and leader capability degree have effect in positive direction.
