These days, according as the role and function of science and technology become a important solving means of various national and social problems caused in knowledge information society as well as the development of national economy, the national target and mission of science and technology have been newly illuminated. The task of science and technology has embodied into national policies, and these policies acquired institutional foundation through the legal system related to science and technology. Recently, the discussions about the operating system of present science and technology legislation are often happened, if or not the legal system is optimal and appropriate itself under the changed environment. In special, some issues are raised continuously, for example, about the improvement of coordination system on S&T policies, and the governance system on national R&D programs, etc. This paper aims to research and suggest the reorganization method of science and technology law. For this purpose, the development and existing state of S&T legislation was investigated, the government role and policy driving direction were reviewed under the recent changed environment, and the problems of S&T law in structure and content were analyzed in variety of perspectives. On this basis, the reorganization methods of science and technology law are suggested.

C-ITS(Cooperative Intelligent Transport System) that pursues traffic safety and convenience uses various sensors to generate traffic information. Therefore, it is necessary to improve the sensor-related technology to increase the efficiency and reliability of the traffic information. Recently, the role of CCTV in collecting video information has become more important due to advances in AI(Artificial Intelligence) technology. In this study, we propose to identify and track dynamic objects(vehicles, people, etc.) in CCTV images, and to analyze and provide information about them in various environments. To this end, we conducted identification and tracking of dynamic objects using the Yolov4 and Deepsort algorithms, establishment of real-time multi-user support servers based on Kafka, defining transformation matrices between images and spatial coordinate systems, and map-based dynamic object visualization. In addition, a positional consistency evaluation was performed to confirm its usefulness. Through the proposed scheme, we confirmed that CCTVs can serve as important sensors to provide relevant information by analyzing road conditions in real time in terms of road infrastructure beyond a simple monitoring role.

Efforts are being made internationally to pay attention to the landscape value of modern and contemporary heritage and to pass it on. However, in Korea, the registration of modern and contemporary landscape heritage as registered cultural properties is insignificant. There has also been little discussion on ways to improve the system in this regard. This study sought ways to improve the registration criteria and classification system of the registered cultural property system so that modern and contemporary landscaping heritage could be protected. Currently, the registration criteria for registered cultural properties are not stipulated for each type of heritage, but are stipulated as a single comprehensive standard. Registration criteria should be separately prepared so that the landscape value of the heritage can be reviewed. First, the registration criteria have an important value in understanding the development of landscape culture. Second, well-preserved landscaping reflects or characterizes the times. Lastly, it should be defined as related to the works of major artists or important figures or historical events. The classification system must match the studied building cultural property classification system, and the detailed types of modern and contemporary landscape heritage should be specified. The major classification follows the building cultural property classification system, but parks and green spaces, squares, and gardens, which can be called a single landscape heritage, should be added to the middle classification. Landscaping heritage, such as gardens combined with building heritage, shall be specified in the subcategory based on building use.

Currently, information technologies such as blockchain and metaverse are being innovatively developed in Korea and around the world. The government has defined the innovation of these cyber-related technologies as the fourth industrial revolution and presented the Digital New Deal as an important policy of the Korean version of the New Deal, and is implementing various policies and systems related to it. This situation is expected to affect the development of the real estate registration system in Korea. Moreover, as the Supreme Court is currently promoting the transition to a future registration system, it is necessary to examine whether blockchain technology, which allows parties to exchange value without a third party guaranteeing the transaction, can be used in the real estate registration system. In order to secure the credibility of the real estate registration as electronic information under the registration system that introduces electronic registration and blockchain system, the transparency of transaction identification and real estate registration details should also be recorded using the blockchain system as a way to prevent such crimes and legal disputes. As a solution, it is worth considering how to improve the reliability of transaction identification, recognize the actual examination rights of the registrar in the foundation system of the real estate register, and increase public trust by going through the notarization stage when recording rights such as real rights, and consider how to introduce a blockchain system at this stage to ensure integrity and reliability. In the stage before the current real estate registration and study system is converted to a blockchain system, the clarity, transparency, and consistency of the real estate registration entries with the actual real estate must be established so that the real estate study can finally be recognized as authoritative, thereby ensuring the trust of the transaction parties to the real estate study system that has adopted the blockchain system in the future, and bringing us closer to the goal of real estate transactions in the form of smart contracts between the parties who have trusted it based on transparency and integrity of real estate study in the real estate transaction market.

In Korea, energy policies are actualized through various energy-related plans. Recently, however, as high-ranking plans, which are very vision-oriented, continually set higher sector-by-sector goals, subordinate action plans, which require consistency, encounter distortions in their establishment process. Also, each subordinate action plan reveals limitations in terms of securing flexibility of the plan in responding to uncertainties of the future. These problems pose potential risks such as causing huge social costs. In this regard, with an aim to provide empirical evidence for discussions on improving the procedure for developing and executing Korea's energy plans, this study mainly analyzes the Basic Plan on Electricity Demand and Supply-one of the most important subordinate action plans-in order to explain the problems of the Basic Plan in a logical manner, and potential problems that could occur in the process of sustaining consistency between the Basic Plan and its higher-ranking plans. Further, this paper estimates the scale of social costs caused by those problems assuming realistic conditions. According to the result, in the case of where maximum electric power is estimated to be 7% (15%) less than the actual amount in the Basic Plan on Electricity Demand and Supply, the annual generation cost will rise by 286 billion won and (1.2 trillion won) in 2020. Such social costs are found to occur even when establishing and executing the Basic plan according to the target goal set by its higher-ranking plan, the National Energy Master Plan. In addition, when another higher-ranking GHG reduction master plan requires the electricity sector to reduce emissions by additional 5% in the GHG emissions from the right mix in electricity generation with 'zero' cost of carbon emission, the annual generation cost will rise by approximately 915 billion won in 2020. On the other hand, the analysis finds that since economic feasibility of electric powers in Korea varies significantly depending on their type, Korea is expected to face very small potential social costs caused by uncertainties over the future price of carbon dioxide in the process of establishing the Basic Plan.

In this paper, an accurate method to estimate the measurement uncertainty of a power amplifier was proposed. Because power amplifiers incorporate mismatch at the drain for the optimal performance, the general method is not enough to produce precise measurement uncertainty of the output power. In order to supplement this method, We suggest comprehensive power measurement uncertainty which is utilized by a complex reflection coefficient and measurement uncertainty of S-parameter which contain the mismatch at the drain on the power amplifier. After that, we compared it with real measurement results of the 10 watt power amplifier which operates on 3.7 GHz. As a result, suggested measurement uncertainty could obtain the uncertainty of output power near 10 times accurate in comparison with existing uncertainty calculation method.

This paper proposes a new way to verify the performance of an absorber lined shielded enclosure(ALSE) in accordance with CISPR25, EMC standards dedicated to testing automotive components. CISPR16 requires the use of NSA and VSWR methods to test the performance of a chamber. As for CISPR25, however, there hasn't been standardized ways to verify the performance of ALSE. This paper purports to present an improved method for the verification based on a long-wire antenna method under discussion at CISPR25 JFT. Existing discussions on a long-wire antenna method proposes that an antenna should reach 500 millimeters in length, while this paper adopts the antenna length of 1,700 millimeters. This paper also assesses the effects of matching conditions and studies problems related to methods which have been already proposed and key parameters in order to improve verification methods.

It is difficult to assemble independently developed software components because of discrepancies between their interfaces. In order to resolve such problem, we propose a new component model, Active Binding Technology, in which each component has its own independently-defined interface for service request that is revealed in its metadata, instead of passively following the interface of a service-providing component. This model Includes the use of the glue component, an interface mediating place, whose template code is automatically generated by reading in the metadata of the components to be combined. We also propose a runtime framework that holds the pool of component instances, completes the assembly of components in the manner of dependency injection, and performs middleware services and real-time system monitoring through glue components. In order to test the practical value of Active Binding Technology, we have made a tool, which supports the development and assembly of Active Binding components.

구리는 현재 반도체 배선으로 가장 많이 사용되는 재료이다. 배선기술이 발전함에 따라 배선두께가 얇아지게 되었고 배선간의 간격 또한 좁아지게 되었다. 간격의 감소는 RC delay 문제점을 야기하였고 이를 해결하기 위해 배선 사이에 Low-k물질을 채우는 노력이 지속되었다. 이상적으로 가장 낮은 유전율을 나타내는 물질은 공기 즉, 아무것도 채우지 않는 것이다. 하지만 이렇게 되면 기계적인 문제가 발생하는데 이를 해결하기 위해서 구리의 강도를 향상시켜야 한다. 강도를 높이려면 Hall-Petch 관계에 의해 결정립의 크기를 작게 만들어야 한다. 그렇지만 이는 곧 전기전도도의 감소를 나타내기 때문에 소자의 구동에 문제가 되어왔다. 이 문제를 해결하기 위해 펄스전해증착을 통한 나노사이즈의 쌍정구조를 가지는 구리의 개발이 진행되었다. 나노쌍정구리는 결정립이 정합면으로 이루어져 있는 쌍정구조로 이루어져 있어 전기전도도의 감소를 최소화하고 강도를 비약적으로 향상시킬 수 있을뿐더러 연신율도 높일 수 있다는 장점을 가지고 있다. 이렇게 고강도 저저항을 나타내는 나노쌍정구리는 Via filling, Through Silicon Via(TSV)에서의 칩간 연결 배선, 2차전지의 전극 등에 적용 가능성이 매우 높다. 이들은 주로 첨가제와 함께 전해증착을 통해 제작된다. 하지만 이러한 첨가제를 넣고 나노쌍정구리를 합성하기 위해 펄스전해증착을 시행할 경우, 나노 쌍정구리의 형성이 억제되고, Off-time이 존재하지 않는 일반 전해증착에서와는 다른 현상이 나타나게 된다. 이러한 이유로 본 연구에서는 현재 가장 많이 사용되고 있는 첨가제인 Poly (ethylene glycol) (PEG, 억제제)와 bis (3-sulfopropyl) disulfide (SPS, 가속제)을 사용하여 그 이유를 알아보고 첨가제를 사용하면서 나노쌍정구리의 밀도를 높일 수 있는 방안에 대해서 실험을 진행하였다.
