Registration between image and object space is a fundamental step in photogrammetry and computer vision. Along with rapid development of sensors - multi/hyper spectral sensor, laser scanning sensor, radar sensor etc., the needs for registration between different sensors are ever increasing. There are two important considerations on different sensor registration. They are sensor invariant feature extraction and correspondence between them. Since point to point correspondence does not exist in image and laser scanning data, it is necessary to have higher entities for extraction and correspondence. This leads to modify first, existing mathematical and geometrical model which was suitable for point measurement to line measurements, second, matching scheme. In this research, linear feature is selected for sensor invariant features and matching entity. Linear features are incorporated into mathematical equation in the form of extended collinearity equation for registration problem known as photo resection which calculates exterior orientation parameters. The other emphasis is on the scheme of finding matched entities in the aide of RANSAC (RANdom SAmple Consensus) in the absence of correspondences. To relieve computational load which is a common problem in sampling theorem, deterministic sampling technique and selecting 4 line features from 4 sectors are applied.

A rapid decrease of total fertility rate to 1.08 in 2005 prompted the Korean government to plan and implement a '5-year plan for ageing society and population policy' starting from 2006. The 1st and 2nd 5-year plans had not shown any discernible impact on the fertility and the 3rd 5-year plan was launched in 2016. However, the fertility rate is going down further. The author reviewed the contents and assessment reports of the fertility promotion plan to suggest ideas for complementing the shortcomings of it. Author defined the major determinants of marriage and child birth as philosophy, politics, sense of value, social norm, culture, healthcare, and education. The plan was examined in view of these determinants. Transformation of Korea from an agricultural society to an industrialized society in a short period of time had brought about changes in most of the determinants of marriage and child birth; in particular philosophy and sense of value. These aspects were not put into consideration in the plan. Author suggested to launch a social education program for the general public to establish a sound philosophy of life, reform the sense of value on family, child birth and education, and cultivate the skill to draw a consensus through discussions on the social issues. A special program to promote marriage of women at the optimum age for child birth was proposed. The government should implement well balanced policy for economic development and labor. Multidisciplinary approach was recommended for these tasks.

Theoretical benefits and research findings on the use of Microcomputer-based Laboratory (MBL) are considered for using MBL in a way that will be of benefit to students and teachers, and discussed as a whole for further synthesis, including the formulation of a research agenda for future consensus-based action. Based on the findings obtained from a comprehensive review of the literature, using a systematic approach, the uses of MBL were compared and contrasted for advancing understanding of the teaching and learning processes in science and mathematics. A number of benefits were proposed by MBL developers but not investigated by educational researchers. A few research studies considered the following practical aspects raised by classroom science teachers: technical problems of MBL equipment; inaccuracy or incompleteness of presentation; efficient ways for handling class time with MBL instruction; and development of MBL curriculum materials for their own instruction. This lack of research related to the use of MBL in science classrooms resulted in educational research that was neither respected nor utilized by science teachers. Setting a research agenda based on the theoretical benefits and research findings is necessary for the effective use of MBL in science classrooms can help to maximize the prospects for successful school improvement projects while minimizing the innovation-related frustrations of individuals.

The development of science and technology not only improved the quality of life of human being, but also brought about environmental problems. Consequently, consensus has been established that early environmental education for youngsters is critical for the preservation of clean environment. A conventional way of teaching has not been very effective for changing their attitude and behavior regarding environmental problems. STS program, which has been one of the major trend in science education, intends to teach science through everyday experience rather than knowledge. This study purports to examine the effectiveness of STS program on environmental problems compared to conventional teaching method. Six week program was developed and applied to subchapter 'Environmental Pollutions & Our Lives' of 3rd grade middle school science text book. The results of this study can be summarized as follows. 1. STS program was significantly effective in changing students' attitude(p<.001). It was effective not only changing their thinking but also changing their behavior. 2. There was no difference between the STS program and conventional teaching method in improving students' knowledge(p>.05). 3. The correlation between the level of knowledge achievement and the attitude on environment was very low(r=.0564,p>.05).

소프트웨어의 개발, 유지보수 및 확장을 용이하기 하기 위하여 프로그래밍 언어에 여러 추상화 기법이 도입되었다. 그러나 추상화와 연관된 여러 개념과 용어가 통일성이 있게 정의되지 못하므로 인하여 관점에 따라 다르게 설명되기도 한다. 특히 추상화를 가장 강력한 기반으로 하여 태동된 객체 지향 패러다임에서 이러한 혼란은 아직도 계속되고 있는 실정이다. 본 논문에서는 프로그래밍 언어에서 가장 중요한 추상화의 하나인 절차적 추상화를 분석하고 이에 대한 유형을 살펴본다. 이를 통하여 절차적 추상화가 지금까지 일반적으로 인식되어온 '처리과정을 기능으로 바꾸는 추상화'라는 기본적인 추상화의 개념 외에도 '추상화에 대한 추상화'의 개념이 내포된 고수준의 추상화도 포함되어 있음을 밝힌다. 또한 절차적 추상화와 관련된 다형성을 추상화의 관점에서 설명한다. 이러한 분석과 고찰을 통하여 절차적 추상화에 대한 수준 높은 이해가 이루어질 수 있을 것이다.

The safe management of radioactive waste is a national task required for sustainable generation of nuclear power and for energy self-reliance in Korea. Since the initial introduction of nuclear power to Korea in 1978, rapid growth in nuclear power has been achieved. This large nuclear power generation program has produced a significant amount of radioactive waste, both low- and intermediate-level waste (LILW) and spent nuclear fuel (SNF); and the amount of waste is steadily growing. For the management of LILW, the Wolsong LILW Disposal Center, which has a final waste disposal capacity of 800,000 drums, is under construction, and is expected to be completed by June 2014. Korean policy about how to manage the SNF has not yet been decided. In 2004, the Atomic Energy Commission decided that a national policy for SNF management should be established considering both technological development and public consensus. Currently, SNF is being stored at reactor sites under the responsibility of plant operator. The at-reactor SNF storage capacity will run out starting in 2024. In this paper, the fundamental principles and steps for implementation of a Korean policy for national radioactive waste management are introduced. Korean practices and prospects regarding radioactive waste management are also summarized, with a focus on strategy for policy-making on SNF management.

Molecular docking is a critical event which mostly forms Van der waals complex in molecular recognition. Since the majority of developed drugs are small molecules, docking them into proteins has been a prime concern in drug discovery community. Since the binding pose space is too vast to cover completely, many search algorithms such as genetic algorithm, Monte Carlo, simulated annealing, distance geometry have been developed. Proper evaluation of the quality of binding is an essential problem. Scoring functions derived from force fields handle the ligand binding prediction with the use of potential energies and sometimes in combination with solvation and entropy contributions. Knowledge-based scoring functions are based on atom pair potentials derived from structural databases. Forces and potentials are collected from known protein-ligand complexes to get a score for their binding affinities (e.g. PME). Empirical scoring functions are derived from training sets of protein-ligand complexes with determined affinity data. Because non of any single scoring function performs generally better than others, some other approaches have been tried. Although numerous scoring functions have been developed to locate the correct binding poses, it still remains a major hurdle to derive an accurate scoring function for general targets. Recently, consensus scoring functions and target specific scoring functions have been studied to overcome the current limitations.

Taekwondo has been known as one of the most symbolic korean sports to publicize Taekwondo various groups have performed exhibitions. These exhibition performances have gained popularity domestically and globally due to the exhibitions' display of artistry and technical mastery. Performance wear has also received wide exposure and thus needs artistic symbolism and functional considerations. This study was done to develop Taekwondo exhibition performance wear for K-Tigers, one of the most active Taekwondo exhibition performing groups. Investigation of current Taekwondo exhibition performance wear and interviewing with K-Tigers members and staff were conducted before designing the uniforms. Interviews demonstrated 3 guidelines: First, the uniforms should not be too different from the traditional wear, but still look unique. Second, it should symbolize the Korean spirit and culture. Third, it should be casual and trendy enough to appeal to young people. Based on these guidelines, 3 styles were made: Dobok style, Hanbok style and Casual style. 5 final designs were selected among 75 sketches with the consensus of the K-Tigers members. This was followed by the 3-step correction process: wearing, check fitting, and correcting design and pattern to provide satisfaction to wearers, and give more detailed information to Taekwondo performance wear design.

Medical ethics has been integrated into the curriculum for medical education in Korea for over 30 years now. There have been many attempts to establish standards for the educational objectives and curriculum, including establishing learning outcomes and publishing medical ethics textbooks in Korean. However, this task is not easy for several reasons: the interdisciplinary nature of the subject, educators' lack of experience, and the lack of a consensus on the criteria that would be effective educational goals. In this article, the author explores (1) the need for reflection on the education itself, (2) two perspectives of medical ethics education, (3) critical perspectives on the effectiveness of the current medical ethics education, and (4) the variety of modalities of medical ethics education. Further, the author proposes a way to teach medical ethics in Korea. The contents and means are closely related to the question of philosophy of medical education: "Should professional ethics education be 'realistic' or 'idealistic'?" Ethics requires educators to be open to new learning experiences and to ethical development. Medical Ethics education should be relevant to everyday clinical experiences and, at the same time provide students and educators to critically review their ethical perspective through reflections.

While efforts to measure and monitor children's well-being have gained increasing recognition across the OECD, there has been relatively little research on the subject of indicators of children's well-being in Korea. This study was undertaken in order to develop the domains and indicators which can be used to measure the quality of life of Korean children from birth to age 17 and to put forward a possible well-being index for Korean children. The 35 indicators of well-being were grouped into eight domains and were designed for this study, using previous research on key child indicators for Korea and the child well-being index in foreign countries, such as the FCD-Land Index, Kids Count, the index of child well-bing in the European Union and OECD area. These domains are composed of the following : economic well-being, health, education, spiritual/emotional well-being, children's relationships, civic participation, safety/risk behavior, and housing and environment. The establishment of a Korean children's well-being index requires access to and use of national statistical data analyzed annually by the government as well as a general consensus regarding such issues as scope and its indicators.
