미학적인 디자인이 상품가치를 갖게 될 현재 사회에서 디자인은 기존의 개념을 탈피하고 파괴하는 반동의 에너지와 부드럽고 유연한 감성을 불어넣는 것이어야 한다. 이러한 디자인 목표에 이르기 위한 '창조적 발상'은 디자이너가 갖추어야 할 가장 중요한 능력 중의 하나이며, 형태적 접근이나 이미지 개발은 물론 기능이나 성능 등 상품 컨셉(Concept)까지 관여하는 디자인 문제해결에 있어서의 총체적인 개념이다. 본 연구에서는 창조성의 정의, 디자인의 환경변화와 그에 따른 디자이너가 갖추어야 할 조건, 선행연구 된 창조적 디자인 발상법 등을 살펴보고 휴대폰을 대상으로 창조적 디자인 사고를 위한 디자인 방법을 제시함으로써 창조성의 중요성과 디자이너의 창조적 가치 향상에 기여하고자 한다.

The purpose of this study is to develop a Framework for Performance Assessment in Science Education(FPASE). Science educators in the past have paid more attention to science curriculum and teaching strategies than assessment. In recent years, attention has turned toward performance assessment which addresses the concerns of science curriculum and instruction, and which is consistent with goals of science education at various levels of interests. Science educators are trying to do performance assessment, yet they don't have a framework that is highly qualified in terms of science educational objectives for the future, and advantages of performance assessment. We, therefore, have developed a framework for performance assessment in science education, which may be useful for science teachers to understand and assess their students' abilities. We have extracted seven domains covering students' various abilities as the important objectives of science performance assessment and grouped them into three categories: General, Science specific, and Intermediate abilities. And we developed a F-PASE with a three dimensional solid figured structure, and illustrated it as the configuration of a com. F-PASE is useful for science teachers to develop and select a science performance assessment as well as have a more advanced understanding of their students' abilities. It is a creative and novel assessment framework in terms of structure, configuration, functions and meanings. It also suggests a new vision of an assessment framework in science education.

The multi scale wavelet-Galerkin method implemented in an adaptive manner has an advantage of obtaining accurate solutions with a substantially reduced number of interpolation points. The method is becoming popular, but its numerical efficiency still needs improvement. The objectives of this investigation are to present a new numerical scheme to improve the performance of the multi scale adaptive wavelet-Galerkin method and to give detailed implementation procedure. Specifically, the subdomain technique suitable for multiscale methods is developed and implemented. When the standard wavelet-Galerkin method is implemented without domain subdivision, the interaction between very long scale wavelets and very short scale wavelets leads to a poorly-sparse system matrix, which considerably worsens numerical efficiency for large-sized problems. The performance of the developed strategy is checked in terms of numerical costs such as the CPU time and memory size. Since the detailed implementation procedure including preprocessing and stiffness matrix construction is given, researchers having experiences in standard finite element implementation may be able to extend the multi scale method further or utilize some features of the multiscale method in their own applications.

In an attempt to develop comprehensive evidence-based methods for evaluation of the R&D performance of cross-disciplinary projects, a joint bibliometric analysis of patents and publications was performed for two industry-university-government collaborative projects aimed at commercialization: Hokkaido University Research & Business Park Project (2003-2007; 63 inventors; 176 patents; 853 papers), and Matching Program for Innovations in Future Drug Discovery and Medical Care - phase I (2006-2010; 46 inventors; 235 patents; 733 papers). Besides the simple output indicators (for five years period), and citations (from the publication date to the end of 2012), science maps based on the network analysis of words and co-authorship relations were generated to identify the prominent research themes and teams. Our joint analysis of publications and patents yields objective and mutually complementing information, which provides better insights on research and commercialization performance of the large-scale projects. Hence, such analysis has potential for use in the industry-university project's performance evaluation.

영재선발을 위한 교사 관찰 추천의 타당성 문제가 꾸준히 제기되고 있는 가운데, 이 연구는 과학영재 선발을 위한 교사 추천(지명)의 타당성을 분석하고자 하였다. 타당성의 준거변인으로 과학적 문제해결력, 과학적 태도와 같은 영역 특수적 변인과 확산적 사고, 창의적 인성, 내재적 동기, 리더십과 같은 영역 일반적 변인이 사용되었다. 현재 영재교육을 받고 있는 과학영재 학생, 영재교육을 받은 적은 없지만 교사에 의해 영재로 판단되어 추천된 잠재영재 학생, 그리고 일반학급의 학생들이 연구대상으로 참여하였다. 분산분석 결과, 창의적 문제해결력의 하위 변인인 독창성과 확산적 사고의 하위 변인인 유창성과 독창성을 제외한 모든 변인에서 영재학생/추천학생과 일반학생 간에 유의한 차이가 발견되었다. 즉, 영재학생/추천학생은 이들 변인에서 일반학생보다 우수한 것으로 나타났다. 판별분석 결과, 영재학생/추천학생을 일반학생과 유의하게 판별해주는 함수가 도출되었으며, 판별함수에 부하된 변인은 독창성을 제외한 과학 창의적 문제해결력과 과학효능감으로 나타났다. 이러한 결과는 교사가 과학영재 학생을 추천할 때 논리적 사고나 문제해결력, 과학수행, 그리고 이로 인해 강화되는 과학효능감과 같이 보다 '적응' 지향적인 학문적 탁월성을 고려하는 반면, 다양한 새로운 반응들을 신속하게 생성해내는 '혁신' 지향적인 속성(유창성이나 독창성으로 나타나는)은 덜 고려한다는 것을 말해준다. 또한 교사추천의 기준은 학문적 탁월성을 지향하는 과학영재교육기관의 선발기준과도 부합하며, 이러한 기준으로 영재를 판별할 때는 교사추천만으로도 영재판별이 가능함을 시사한다.

We developed a highly accurate, yet inexpensive, refractive index (RI)-based soil moisture sensor. To detect the RI, a light guide was set with a light-emitting diode and photodiode. When the air fills the space between the soil particles, most of the incident light is reflected at the interface between the waveguide and the air because of the large RI difference. As the moisture of the soil increases, the macroscopic soil RI increases. This allows incident light to pass through the interface. The intensity of the light reaching the photodiode was simulated according to the change in the soil RI. Using the simulation results, we designed and manufactured a curved glass waveguide. We evaluated the performance of the RI-based soil sensor by comparing it with a commercially available, high-cost and high-performance time-domain reflectometer (TDR). Our sensor was 96% accurate, surpassing the costly TDR sensor.

A new chromatographic stationary phase has been prepared by cross polymerization between allylsilica and perallyloxycucurbit[6]uril and characterized by elemental analysis and FT-IR spectroscopy. The double endcapping has been proven to improve the separation efficiency of the cucurbituril-based stationary phase material. The first end-capping was carried out when allylsilica was made. The second end-capping was done as the final step of the whole process, and the use of a mixture of hexamethyldisilazane (HMDS) and trimethylchlorosilane (TMCS) as an end-capping reagent was found better than the use of only HMDS or TMCS. Our stationary phase has shown generally good results in separation of nonpolar and polar analytes. This phase showed even better separation performance than the commercial C18 phase for the case where hostguest chemistry was properly incorporated in solute retention.

This study explores on the static and dynamic growth patterns of high-tech ventures in Korea. We developed an integrative framework with target market (local vs. global), product/market maturity (existing vs. emerging), and technological capability (follower vs. pioneer). We also identified seven new ventures strategies as follows: i) reactive imitation, ii) proactive localization, iii) import substitution, iv) creative imitation, v) early market-entry, vi) global niche, and vii) global innovation. With five successful Korean new ventures, we found different competitive behaviors and performance among new venture strategic types. This study also observed two different growth patterns: growth through strategic replication and growth through strategic change. It depends on whether they are pursuing similar strategy over time or different strategy within for growth. In addition, we found that creative imitation plays a stepping-stone role in two-step internationalization processes. Although this study is exploratory and needs more empirical studies, it can provide new ventures with meaningful guidelines for growth and internationalization with a dynamic perspective.

Electronic brainstorming (EBS) to improve the process and outcomes of group decision making is an artifact of Information Systems legacy. Despite three decades of research with EBS in an effort to become a key resource of organizational performance, its performance when compared to that of nominal is inconclusive because of the recent debate over its usefulness in terms of productivity. Subsequent researchers have directed our attention to the re-examination of cognitive stimulation, which is considered the major benefit in computer-based idea generation, to explain the performance singularity in computer-based groups. While both cognitive and motivational factors that moderate and mediate the group-interaction process remain unexplored, individual differences that are tightly linked to creative behavior have been largely ignored to account for the discrepancy in performance. Since simulations have been widely used in situations where an outcome does not meet the assumptions, the notion of a group simulator and detailed simulation mechanisms are introduced to examine the potential effects of individual differences on the performance of computer-based idea generation groups. In addition, two prior studies that empirically explored cognitive mechanisms with the group simulator are showcased along with six propositions to initiate future research.
