  • 과학영재 교육의 목적과 효과를 달성하기 위해서는 과학영재들의 특성, 과학영재의 판별이나 교육 프로그램의 개발, 과학영재들의 과학, 과학자, 과학관련 직업에 대한 인식 등 여러 요소들에 초점을 맞추어 연구해야 하며 이를 바탕으로 교육해야 한다. 과학영재교육의 중요한 점 중 하나는 우리가 교육하는 과학영재들이 성장해서 그들의 영재성을 발휘하도록 하는 것에 있다. 이는 국가적으로도 매우 중요한 일이다. 과학기술의 발달과 국가의 발전은 뛰어난 영재들이 기여를 하였으며 그 업적을 통해 국제경쟁 사회를 선도해 나갈 수 있기 때문이다. 과학영재 교육의 성공 기준 중 하나로 노벨상 수상을 기대하는 것이라고 생각할 수 있다. 물론 노벨상만을 목표로 하는 것은 과학영재교육이 왜곡될 수 있으나, 과학영재교육을 통해서 과학 분야에 뛰어난 인재를 양성하고 이들로부터 과학의 수준이 높아지면서 자연스럽게 노벨상을 수상할 수 있을 것이다. 2002년 노벨 과학상에서 일본은 물리학과 화학 두 분야에서 수상자를 배출하였다. 특히 노벨 화학상을 받은 다나카 고이치는 박사학위도 없는 40대의 평범한 회사원이었다. 그는 일본 과학계를 장악하고 있는 유명 국립대학의 교수도 아니고, 수상 발표 뒤 대부분의 일본 화학자들이 누군지 몰라 당황했을 정도로 잘 알려지지 않은 인물이었다. 이러한 사건은 일본인들에게 희망을 안겨주었으며 과학 및 과학자에 대한 관심과 투자에 대한 인식에 있어 많은 변화를 초래하였다. 노벨상 자체가 국가정책의 목표가 될 수는 없지만, 과학자나 국민 개개인들에게 희망이 되는 것은 사실이다. 해마다 노벨상 수상자가 발표되는 시점에서 우리들은 아주 오랫동안 방관자가 되어 왔다. 이제 여러 과학영재교육기관 등을 통해서 과학영재 교육을 효율적으로 실시한다면 조만간 상황이 바뀔 것으로 기대할 수 있다.택한 이유는 첫 번째가 사회 봉사와 국가 발전에 기여하기 위한 것이었으며, 다음으로는 생활의 안정을 꼽고 있었다. 이외에도 과학적 업적 달성을 위해, 자신의 꿈(이상) 실현을 위해 등의 이유를 들고 있었다. 이러한 경향은 남자 영재와 여자 영재들간에 다소 차이는 있었으나 거의 유사한 것으로 조사되었다(Pearson $X^2$=2.186, p>0.05). 우수한 능력을 소유한 영재들이 과학관련 분야를 선호하지 않는다면 우리나라의 과학 발전은 그리 낙관할 수 없을 것이다. 그러므로, 영재들을 과학 관련 분야로 이끌어 그들이 소유한 영재성을 발휘하도록 하는 것은 매우 중요한 일일 것이다. 이룰 위해서는 과학 영재들이 자신의 능력에 대한 자신감을 더욱 높여야 하며 그 능력을 과학관련 분야에 발휘하도록 하기 위한 국가적, 사회적, 교육적 노력이 필요하다. 노력이 필요하다.~42.1mg$CO_2$/kg.hr였으며 12$^{\circ}C$에서 2.5~8.2mg$CO_2$/kg.hr로 일반적으로 보고되고 있는 토마토 호흡속도와 일치하는 결과를 나타내었다.다.환원당인 sucrose 함량은 계속 증가하였고 fructose, glucose, sorbitol의 함량(추황의 sorbitol을 제외)은 생장이 촉진됨에 따라 증가하다가 다시 점차적으로 감소하였다. 이러한 결과는 총당과 환원당의 측정결과와 일치한 것으로 나타났다. 결론적으로 배의 성장에 따라 산 함량은 감소하였고 당 함량은 증가하였다.luco-pyranoside, quercetin 7-O- -glucopyranoside, acacetin 7-O-$\beta$-D-glucuronide and apigenin-6-C-$\beta$

  • The buffer is a key component of the engineered barrier system in a high-level radioactive waste (HLW) repository. The present study reviewed the requirements and functional criteria of the buffer reported in literature, and also based on the results, proposed an approach to establish a buffer concept which is applicable to an HLW repository in Korea. The hydraulic conductivity, radionuclide-retarding capacity (equilibrium distribution coefficient and diffusion coefficient), swelling pressure, thermal conductivity, mechanical properties, organic carbon content, and illitization rate were considered as major technical parameters for the functional criteria of the buffer. Domestic bentonite (Ca-bentonite) and, as an alternative, MX-80 (Na-bentonite) were proposed for the buffer of an HLW repository in Korea. The technical specifications for those proposed bentonites were set to parameter values that conservatively satisfy Korea's functional criteria for the Ca-bentonite and Swedish criteria for the Na-bentonite. The thickness of the buffer was determined by evaluating the means of shear behavior, radionuclide release, and heat conduction, which resulted in the proper buffer thickness of 0.25 to 0.5 m. However, the final thickness of the buffer should be determined by considering coupled thermal-hydraulic-mechanical evaluation and economics and engineering aspects as well.

  • This study aimed to evaluate correlation between self-evaluation factors and academic achievement of medical students according to introduction of explanation meeting in cadaveric dissection. The students explained cadaveric structure to health allied sciences students and discussed with each other. Just after the meeting, 102 medical students filled out a self-reported questionnaire on impact of self-evaluation factors and communication. The data were analyzed by frequency analysis, t-test and analysis of variance. Regardless of their gender, age, previous experience, the majority of the students gave high scores in all of self-evaluation factors. Among them, linkage with major and verbal communication factor were closely related to their academic achievement(p<0.05). The verbal and non-verbal communication factors also had a high correlation of 0.580(p<0.01). The explanation meeting provided a chance to learn further with positive attitude to medical students and motivated them academically.

  • Germany has carried out its environment friendly energy policy to prevent $CO_2$ emission that affects directly to the global warming phenomenon. Based on this direction, it has performed a sustainable development strategy through the R & D activities in environment and energy technologies. Accordingly, the core elements of German energy and sustainable development policies are renewable energy, ecological energy tax, and emission trading system. In particular, Germany has supported to develop renewable energy resources that prevents from consuming fossil energy resources. At the same time, it has set the ecological energy tax and initiated the emission trading system in order to support the renewable energy policy continuously. This paper analyze whether or not it is possible to generate an economic growth and a sustainable development while using renewable energy resources based on the renewable energy policy that minimize the negative effects on the environment. For that, the paper adopts Germany as a model country. In fact, it is possible to achieve the economic growth and the sustainable development if a nation can substitute increasing energy consumption for the economic growth to renewable energy resources that does not affect to the environment negatively. This model is the German energy policy and sustainable development strategy, and it is the purpose of the paper to prove it logically.

  • Mega-corporations are emerging as a result of M&As (mergers and acquisitions) in the logistics industry. The global logistics market has progressed in a continuously competitive manner. Global logistics corporations provide integrated set of services, from production to disposal in order to manage the process efficiently throughout the diverse regions of the world. To advance into an total integrated logistics provider, the corporation must have professional knowledge in logistics and information technology which are necessary to deliver effective integrated logistics solutions. The government has integrated the logistics corporations both horizontally and vertically with the aim to foster logistics corporations possessing global competitiveness. Six years have passed since the implementation of the comprehensive (total) logistics industry certification system in pursuit of making Korea the hub for the Northeast Asian logistics market. This study compares and analyzes the efficiency of nine mega integrated logistics providers by applying the CCR model and BCC model. Each of the nine corporations is subject to certification as integrated logistics corporations. In Korea, nine corporations are certified individually as integrated logistics corporations out of the 31 logistics providers. The analysis showed that the Glovis was the most efficient integrated logistics provider reaching 100% in efficiency and displayed the highest efficiency for six consecutive years from 2005 to 2010. The study also found that the Glovis will be able to maintain 100% in efficiency rate, even though the input are increased over six times as many as those of 2010.

  • While the trend of all industries recently lies in combination, construction industry is much interested in enhancing efficiency and competitiveness in the aspect of site control by adopting RFID. Though RFID has been applied to diverse areas thus far, it cannot be easily applied to construction industry due to diverse physical, chemical and use-environmental properties of construction materials. Furthermore, it is rarely applied to the site because of many problems in its application. It is required to prepare RFID code issuance and system that can systematically control the code as well as to research the standardization of frequency, specification, protocol, package method, recognition method, etc in order to apply RFID to construction industry. In this research, RFID code issuance and management program are proposed as a part of program research to apply RFID. Furthermore, the restricted matters of existing RFID tag are drawn to produce pilot product of RFID tag that can solve it so as to perform site application test. According to the experiment, effective recognition distance varies depending on material/environmental property and control efficiency changes depending on attachment method and application method. Thus, preparing diverse restrictive factors and solutions by systematically analyzing control method(medium, process) of current architecture materials and applying it to construction site can be the way to successfully apply RFID.

  • Recently, the scope of user interface is increasing the relative importance in software development dramatically. As a result, there are various relative technologies like as SWING, MFC, Web 2.0, and etc. However, most current software developments are progressed in separate development process with user interface part and business part respectively. This causes the problems, like as a difficulty in the integration process, an development period's delay, and a poor reusability for the constructed models. That is, the extendability and reusability of the created models is being decreased because UI modeling is not systematic and hierarchical, and the consistent integration technique between UI modeling and business modeling does not supported. To solve these problems, this paper proposes an unified and systematic UI modeling process based on UML, using the hierarchical metamodel according to the abstraction levels of development phase. We suggest an UI metamodel, which contains a hierarchy by layering the modeling elements in PIM and PSM based on maturity degree of the development. An hierarchical modeling process combined UI modeling and business modeling is built by applying the UI and business metamodel in terms of three modeling phases(concept/specification/concrete). The effectiveness of the modeling process is shown by applying the proposed process into an Internet Shopping Mall System. Through the exploratory results, the hierarchical UI metamodel and process can produce systematic and layered UI models. This can improve the quality and reusability of models.

  • U-City laws are divided into three categories: intellectual laws, information superhighway laws, and integrated operation center laws. Previous studies have suggested that efficient infrastructure operation and management is necessary in Ubiquitous-City (U-City). However, infrastructure is often interpreted differently by different laws. The purpose of this study was to plan for the integrated operation of intelligent service facilities by comprehensively analyzing the law system of domestic intelligent service facilities and problems in operation and management based on this critical mind. For this, present conditions and problems of intelligent service facilities were found through interviews with people who are in charge of the law system and other practitioners. The necessity of integrated use, including city information generated from intelligent service facilities and installment locations, has been demonstrated. Government ministries and local governments have established various information systems using ICT and U-City laws that specify integrated management and operation, but do not clearly specify definitions for the specific responsibility and authority for main agents participating in facility operation. A system is needed to smoothly mediate the relevant divisions so that they can use installed equipment simultaneously for efficient operation in generating city information. This objective of this study was to prepare a unitary law system for efficient installment and management of intelligent service facilities by establishing a logically linked relationship among the relevant laws and regulations. This will provide a foundation for a management system that has an integrated linkage of intelligent service facilities.

  • In this study, we investigated how scientists and teachers engaged in mentoring program are conducting research ethics education and how they are creating an ethical educational environment. A questionnaire survey was given to 32 scientists and 44 teachers conducting mentoring programs for gifted high school students. In the content of research ethics education, most of the respondents opined that they should teach against falsification, plagiarism, and fabrication. Teachers were most likely to teach ethical decision-making in each step of the research process. Most of the scientists said that they should teach how to write research note. For the difficulties, the teachers pointed out the challenging system that focuses only on college entrance exams while the scientists answered that it was difficult to recognize research ethics as the problem of the students themselves. For the teachers, the most affective factor in creating an ethical research environment is the amount of time to teach research ethics while for the scientists, it is the ethics of the mentors. For creating an ethical research environment, the teachers responded with making an atmosphere wherein failure is tolerated, and the scientists responded with increasing the degrees of freedom in results. For the difficulties of creating an ethical research environment, the teachers were constrained by research time while the scientists were pressured about the results. These results provide implications for ways to teach research ethics and for ways to create an ethical research environment in the mentoring program for science-gifted students.

  • This study aims to identify the learning behavior patterns recognized by students to find effective tutoring operational methods, and further analyze the impact of learning behavior patterns on academic performance and learning satisfaction. To this end, 105 participants in the tutoring program at D University based in Busan Metropolitan City collected data and conducted descriptive statistics, correlation analysis and regression analysis according to research problems. First, the study found that students who participated in tutoring had the most environment-dependent and self-taught learning behavioral styles and environment-independent and self-taught learning behavioral style. Second, the correlation between learning behavioral styles and academic achievement and learning satisfaction shows that there is a high correlation between positive and cooperative learning behavioral styles and environment-independent and self-taught learning behavioral styles. Third, regression analysis on academic achievement and learning satisfaction showed that positive and cooperative learning behavioral styles significantly affects learning satisfaction, but environment-independent and self-taught learning behavioral style, environment-dependent and self-taught learning behavioral style, and passive learning behavioral style were not significant. These results suggest that from the school perspective, learning behavior can be recognized as an important factor in students' academic success and failure, so instructors need to check learners' learning behavior patterns and provide appropriate tutoring teaching and learning design plans.
