Hand rehabilitation training tools are used in hospitals and at home for patients and users who require recovery of disabled hands and improvement in overall hand function. However, existing training tools are not organized into a progressive system, and they lead to repeatability operations over a period of time. As a result, patients feel free and cannot be motivated by rehabilitation, and continuous rehabilitation training is difficult. Based on this argument, the study combines one of the elements of the game called the "Cat's cradle" to enable the user to feel achievement through play and to achieve natural rehabilitation through unconsciousness. After examining the characteristics of the tool, the user's environment, the relevance of the Cat's cradle game to the training tool and to the patient's continued rehabilitation was established. And design elements were derived through professional interviews. Later, design guidelines and prototypes have been created to complement the problems associated with guidelines and prototypes by conducting usability testing and design element assessment.

The purpose of this study is to explore the issues and alternatives in the promotion of space and exhibition support projects in visual arts, and to suggest an applicable direction of the government grant program. For this study, FGI and in-depth interviews were conducted in the direct beneficiaries of the grant program, the staff of the grant program, and the group of visual arts expert. As a result, the deliberation and selection of the support project should be carried out with sufficient time in consideration of the specificity of the support project. And the project requires to divide into two kinds of the projects based on the understanding of the social role and differentiation of non-profit exhibition spaces and private art museums. For the grant application and assessments, a long-term support is necessary to bring the capability and issues in efficient allocation of the budget, flexibility of budget item, and the budget shortfalls. Furthermore, the reliability between the grant program and beneficiaries needs to form a healthy partnership, and the evaluation criteria and eNARADOEUM system should be more practical and rationally established. Through this analysis, the implications of understanding the specificity of visual arts support projects, establishment of sustainable visual arts creation policies, and budget utilization were derived. Consequently, cultural and artistic support projects were directed to place more emphasis on efficiency than control, direction considering the position of consumers than suppliers, and long-term business planning rather than short-term perspective.

고도의 정보사회가 될 것으로 예견되는 21세기 전 세계는 창의적이고 원천적인 과학기술을 지속적으로 창출하면서 선진적 우위확보를 위해 치열한 경쟁을 벌이고 있다. 우리나라도 지금까지 이룩한 경제성장을 발판으로 이제부터는 더욱 생산적이고 독창적인 세계 일류 지식과 과학기술을 창출해 내야 할 위치에 있다. 세계적으로 새로운 지식은 대부분 학술지와 도서를 통해 발표되고 있으며, 미국의 과학정보기구인 ISI(Institute for Scientific Information)는 세계의 우수 학술지를 평가하여 그 중에서 가장 영향력이 높은 3~4%의 학술지를 SCI(Science Citation Index), SSIC(Social Science Citation Index), AHCI(Arts and Humanities Citation Index)로 전별하여 발표하고 있음은 잘 알려진 바와 같다. 우리 학계에서도 수 년 전부터 연구업적 등의 평가에 이들 분류를 적극 활용하고 있으며, 개개의 연구자들도 연구성과를 SCI 등에 등재된 학술지에 발표하기 위한 노력을 배가하고 있는 실정이다. 그러나 안타까운 것은 우리나라에서 발간되는 학술지 중 과학기술 분야 단 5종만이 SCI에 등재되어 있을 뿐이어서 우리의 학문이 세계적으로 교류되고 인정받는데 상대적으로 불리한 위치에 있다는 사실이다. 국내 학술지가 이들Index에 등재될 경우 우리의 연구성과가 보다 빠르고 쉽게 국제적으로 소개.인정되며, 이는 우리의 과학기술 수준을 한 단계 높이는데 첩경이 될 것이라는 점은 의심의 여지가 없다. 과학기술 평가과정은 측정 가능한 연구투자와 연구결과 현상으로 간주할 수 있는데, 일반적으로 연구투자는 연구투자에 필요한 모든 요소들이 실체적이며 평가하는 데에 있어서 인력, 재정 자원, 장비, 재료, 건물 등과 같이 구체적이고 경험을 요구하지 않기 때문에 그 모든 연구결과보다 평가하기가 용이하나 과학기술의 연구결과는 연구 과정을 통해 보다 비실체적이고 양적으로 측정하기 어려운 지식으로 구성되어 있어 평가하는데 어려움이 뒤따른다. 과학기술 연구결과를 양적이나 질적으로 측정하는데 있어 일반적으로 이용되는 시스템은 없으나 국가의 과학기술 수준은 보통 그 나라 과학기술 활동의 연구결과를 과학기술 생산성이나 연구결과물 즉 논문 등의 출판을 통한 배포나 인용분석 등에 기초한 양적 평가지표를 이용해 측정하는 서지적 방법에 의해 평가되고 있다.연구활동 결과로 발표된 연구논문은 새로운 연구논문의 자료로 인용되게 되는데, 일반적으로 인용이 많이 된 논문일수록 질적인 가치가 높다고 하므로 논문의 발표량과 인용된 횟수는 연구활동을 평가하는 척도로 활용점에 따라 과학기술분야 논문의 국가별, 기관별, 분야별 논문수와 피인용도는 과학기술 수준 평가의 척도가 될 수 있으며 이러한 평가는 과학기술 정책 수립 및 투자, 연구활동에 대한 평가 등의 중요한 자료로 활용될 수 있다. 과학기술분야 전반에 걸친 SCI 기반의 NSI, NCR 데이터베이스를 분석하여 우리나라 과학기술분야의 수준을 평가할 수 있는 지표를 산출하여 우리나라의 과학기술 수준을 정확히 파악하고, 세계 추세를 분석하여 앞으로 나아갈 정책방향을 설정하는데 도움이 되도록 하며, 국내 기관별, 분야별 분석을 통하여 과학기술 수준을 평가할 수 있는 객관적인 자료를 제공함과 동시에 국내 연구 인력간의 건전한 경쟁을 유도하여 과학기술 발전에 기여하고자 한다.

A deep geological disposal at a depth of 500 m in stable host rock is considered to be the safest method with current technologies for disposal of spent fuels classified as high-level radioactive waste. The most important requirement is that the temperature of the bentonite buffer, which is a component of the engineered barrier, should not exceed $100^{\circ}C$. In Korea, the amount of spent fuel generated by nuclear power generation, which accounts for about 30% of the total electricity, is continuously increasing and accumulating. Accordingly, the area required to dispose of it is also increasing. In this study, various duplex disposal concepts were derived for the purpose of improving the disposal efficiency by reducing the disposal area. Based on these concepts, thermal analyses were carried out to confirm whether the critical disposal system requirements were met, and the thermal stability of the disposal system was evaluated by analyzing the results. The results showed that upward 75 m or downward 75 m apart from the reference disposal system location of 500 m depth would qualify for the double layered disposal concept. The results of this study can be applied to the establishment of spent fuel management policy and the design of practical commercial disposal system. Detailed analyses with data of a real disposal site are necessary.

Aircraft-related accidents cause mass casualties and major material damages. At present, runway-related accidents in our country account for 28% of all air accidents. Furthermore, internationally 33% of all air accidents is connected with runway. To prevent these accidents, FAA mandates the installation of aircraft rapid arresting system(ARAS) at the runway end safety areas which do not meet the FAA requirements. Even if the areas satisfy the conditions, FAA recommends the installation of ARAS to ensure the safety. In accordance of the international affairs, the domestic studies for ARAS are in progress and the legal formalities for domestic adoption of ARAS is under way. In this study, we analyzed the stopping distance, drag force, vertical force and tire penetration of runway overrun to assess the performance of ARAS reasonably by using two different kinds of analysis programs. The first is ARRESTOR program adopted by FAA, and the second is LS-DYNA which is available for 3-dimensional nonlineal dynamic analysis. As a result, analytically the stopping distances between two programs are similar. The drag force is rather different, but the tendencies are similar. Later on, the 3-dimensional simulation analysis considering various air-craft condition and properties of packaging materials is necessary. In addition, ongoing development of simulation analysis program is required for more accurate analistic results.

Several countries are establishing management systems for aquaculture environment, and fishery environment assessment is one of them. The fishery management law amended in 2013 stipulates that a fishery environment assessment should be performed when a fish cage farm's license is extended. The purpose of the fishery environment assessment is to promote sustainable fishery, increase the fishery production capacity, and increase the fishermen incoming by implementing evaluation and improvement measures through scientific methods. The analysis items of fishery environment assessment include the Benthic Health Index (BHI), which is a biological index based on the macrobenthic polychaetes community, and total organic carbon (TOC), and the two items are scored and used for evaluation as a single grade. This study explains the selection process of BHI and TOC, which are evaluation items for fishing ground, and ecological significance of the calculated evaluation grades.

The numbers of multi-year droughts due to climate change are increasing worldwide. Boryeong Dam, located in Chungcheongnam-do, South Korea, was also affected by a 4-year drought from 2014 to 2017. Since traditional unilateral decision making processes to alleviate drought damage have, until now, resulted in conflicts between many of the involved groups, the need for active participation from both stakeholders and policymakers is greater than before. This study introduced Shared Vision Planning, a collaborative decision making process that involves participation from various groups of stakeholders, by organizing Water Policy Council for Climate Change Adaptation in Chungcheongnam-do. A Shared Vision Planning Model was then developed with a system dynamics software by working together with relevant stakeholders to actively reflect their requests through three council meetings. Multiple simulations that included various future climate change scenarios were conducted, and future drought vulnerability analysis results of Boryeong Dam and districts, in terms of frequency, length, and magnitude, were arrived at. It was concluded that Boryeong Dam was more vulnerable to future droughts than the eight districts. While the total water deficit in the eight districts was not so significant, their water deficit in terms of spatial discordance was proved to be more problematic. In the future, possible alternatives to the model will be implemented so that stakeholders can use it to agree on a policy for possible conflict resolutions.

We propose a parallel acquisition scheme using antenna arrays for initial acquisition of direct-sequence spread-spectrum (DS-SS) signals. The proposed parallel scheme can lower substantially the range of detectable signal-to-noise ratio (SNR) as compared to the conventional parallel scheme with a single antenna. The proposed scheme uses the sum of the independent decision samples from antenna arrays corresponding to an identical subsequence of the pseudonoise (PN) code as a decision variable. We derive the probabilities of detection, missing, and false alarm under an additive white Gaussian noise (AWGN) channel and a flat Rayleigh fading channel. Using these, we get the mean acquisition time of the proposed scheme. From numerical results, we see that the acquisition performance becomes improved continually as the number of antennas increases.

The cemetery areas which are occupied more than 1.0 percent of whole land of Korea have widened gradually but the reconnaissance is not being conducted for the cemetery investigation due to deficiencies for budget and manpower of the government. The aim of this study is to find a method to establish the lower cost GIS-based cemetery management system by using hand-held DGPS receiver and Mobile GIS software system for easy cemetery management. The results were evaluated and compared to the RTK GPS method. Since the Cemetery Management System shows every tomb's position on the high resolution satellite imagery with a cadastral data, the map helps to find the interesting places easily. Therefore the system data can be used for various purposes such as planning for land development, dealing with real estate as well as cemetery management.

A study on the sustainability evaluation of the requirements of the mobile industry closely related to the human factor was needed. We conducted the sustainability evaluation of the mobile industry using a quantitative evaluation method with the AHP tool and a qualitative evaluation method reflecting the technological age flow of the philosophical thoughts to improve the reliability of the evaluation results of the model verification. And this evaluation is to evaluate the consistency of the connection between the national sustainability and the mobile industry. In order to draw the conclusion of the relevance, the team member Delphi 5-point scale was used. As a result, the priority was confirmed in the national sustainable development indicator and mobile industry indicator. Quantitative and qualitative evaluation was applied to the discontinued model of mobile to derive insufficient indicators, and it was confirmed that if the indicators were improved and reflected, it would be sustainable. And in order to secure reliability and accuracy, we made a proposal to apply the systems engineering process to the development of the model evaluation field. The systems engineering technology process meets the needs and requirements of stakeholders throughout the lifecycle and it is suitable for the development model of the industry's sustainability assessment.
