The exercise of police power for danger prevention gives top priority to the prevention of injury occurrence. However, the controversy over the concept of danger has hitherto focused on the limit establishment, namely which scope is to be a target of prevention in the danger prevention area of the Police Law. After all, the police's duty for maintaining public peace and order is forced to be performed through individual measures for danger prevention, and the preventive police action, which aims at the prevention of danger against the protection interest in the Police Law, can be performed on the premise of a precise understanding of danger in order to carry out a legitimate preventive police action. In addition, it examines the legal meaning in each constitution element by dividing the minimum common components of danger into loss, sufficient probability and time accessibility, and the interpretation problem of danger as uncertainty concept.

The design of an efficient scheduler is a key design factor in IEEE 802.16m systems, in order to support services with various QoS smoothly. Although conventional studies of schedules have been suggested, those had problems that are not able to satisfy the delay condition and make the through-put declined, because they only focused on a specific action scenario rather than reflecting practical action scenarios which have real-time and non-real-time traffics variously. In this paper, an efficient uplink scheduling algorithm is proposed for IEEE 802.16m system by introducing the concepts of Virtual Time(VT) and Virtual Finish Time(VFT) based priority determination, and separate buffers for each QoS class in the mobile terminal. Simulation results showed that the proposed scheme had satisfied the delay requirement of real-time services even with improved throughput performance compared to conventional methods.

Climate action is at the top of the agenda in the international community, as demonstrated at the 2021 G7 Summit and the 2021 UN Climate Summit. Major developed countries are scrambling to make a transition to a green economy and create a new growth momentum. Following the Paris Climate Agreement in 2016, they focus on "carbon neutrality" as an effective means of tackling climate change. The Republic of Korea, a high-carbon economy, submitted its second Nationally Determined Contribution and announced carbon neutrality as a top policy priority. Accordingly, the country increases government budget in research and development (R&D) and science and technology (S&T) policies. Against this backdrop, this study analyzed policies on carbon-neutral S&T and R&D in major advanced countries. The analysis was made by identifying globally pending issues in carbon-neutral policies and climate technology. In addition, focus group interviews were conducted six times with 10 experts to come up with three R&D strategies and action plans for government-funded research institutes to achieve carbon neutrality. To be specific, the following measures were suggested. First, creative and innovative R&D programs are required to solve the problem of carbon emissions. Second, it is necessary to establish carbon neutrality policies and infrastructure which are sustainable to run and manage. Third, it is crucial to promote cooperation in climate technology based on excellence. In conclusion, the strategies proposed in this study are expected to provide directions and implications for policymakers, researchers, and scholars in science and technology to develop effective strategies to achieve national carbon neutrality.

ODA is an effort and action of international community to keep human rights by eradicating poverty. UN declared MDGs (Millennium Development Goals) during 2001 and 2015. As a follow-up action, UN sets up SDGs (Sustainable Development Goals) during 2016 and 2030. SDGs expands the concept of ODA. SDGs includes cooperation development over the scope of ODA by mobilizing various financial resources from public sectors and private sectors. It will overcome the limitation of traditional ODA and be 'AID and beyond'. Catalytic aid is appropriate for the concept of SDGs. Cooperation development by catalytic aid focuses on building economic infrastructure and production facilities rather than humanitarian aid, which will establish a sustainable development basis for recipient countries. This study suggests to make a PPP business by linking KSP(Knowledge Sharing Program), to objectify criteria of priority recipient selection and aid allocation, to adapt grant and concessional loan complexly according to the business, to support realization of CSV(Creating Shared Value) by establishing SPC(Special Purpose Company) and to construct a PCSD(Policy Coherence for Sustainable Development) system to fulfill the fore-mentioned strategies.

The Broadcasting Law amended in January 2007 declared to adopt universal right to view(known more widely as Universal Access Right, UAR), the right to access broadcasting programs on such major sports or other events that are likely to catch the gaze of the public television viewers. Then its implementation rule was issued in February 2008, and under the regulations the Committee of Ensuring Universal Access Right has been established, where detailed action measures and guidelines are currently in the process of preparing. However, it is no question that an effectiveness of the implementation system of Universal Access Right presupposes sufficient amount of discussion and social consensus. At present, the major focus in this issue is on the matters including which type of events is subject to UAR and what criteria are desirable in determining which broadcasting company has priority. In this context, this study aims at identifying implications for policy by examining the precedent cases of Europe, Australia, and other countries, where UAR is enacted and implemented. Further, this study tries to draw up a specific scheme for ensuring universal right to view through conducting a survey on public television viewers. We will include specific guidelines for selecting events of public attention, criteria for selecting broadcasting companies regarding priority, and relevant operating rules regarding relayed broadcasting.

This study analyzed the globalization policy of ICT SMEs and ventures using cognitive map analysis and derived the priority to importance about action plans using AHP model, while the globalization paradigm has been rapidly changing in the ICT industry. Empirical results showed that policy tool variables should be needed to develop because policy goal variables are generally presented more than policy tool variables. In addition, this cognitive map could be characterized by a scarcity of feedback loops which means policy landscape for ICT SMEs and ventures' globalization is unilateral rather than cyclical to reach policy goal from policy tools. Another finding is that creative economy policy variable was not observed as policy tool variable but as policy goal variable. This means creative economy can be implemented through support for ICT SMEs and ventures' globalization. Finally, for detailed policy measures, installation of global start-up center, recruiting and utilization of global specialists, revitalization of ICT R&D international collaboration study, enlargement of global investment network, accompanied overseas advance of large enterprises and SMEs are presented in order in terms of the importance of policy priority.

With the rapid development of the Internet and information technology, a company that deals with personal information does not have proper action to protect personal privacy and not take measures for the safe handling and management of personal information. It generates the case to abuse of personal information occurring frequently. In order to focus the effort to reduce damage and protect the privacy of personal information entity and enhance privacy laws based on the connection method and the processing of personal information, Korea encourages a company to follow regulation by providing certain criteria. However, in the case of items of measures standard of safety of personal information such as priority applicable criteria in accordance with the importance of itemized characteristics and the company of each individual information processing is not taken into account, and there are some difficulties to execute. Therefore, we derive criteria by law and reviewing existing literature related, the details of the measures standard of safety of personal information in this study and generate a hierarchical structure by using the KJ method for layering and quantification of the evaluation in integration of the reference item similar and the grouping. Accordingly, the weights calculated experts subject using the AHP method hierarchical structures generated in this manner, it is an object of the proposed priority for privacy and efficient more rational enterprise.

In this paper, we propose a schedulatility analysis method for real-time programs. Several approaches to anlayzing schedulability have been developed, but since these approaches use a fixed priority scheduling method and/or traverse all possible state spaces, there take place exponential time and space complexity of these methods, Therefore it is necessary to reduce the state space and detect schedulability at earlier time. Our schedulability analysis method uses a minimum unit time taken to terminate synchronization action, a minimum unit time taken to terminate actions after synchronization, and a deadline of processes to detect unschedulability at earlier time and dynamic scheduling scheme to reduce state space. We conclude that our method can detected unschedulability earlier 50 percent unit time than Fredette's method.

This paper presents a knowledge based system to solve reactive power/voltage control problem in a power system. A need is recognized for new methods to alleviate a bus voltage limit violation more quickly when a power system becomes an emergency state due to contingency. To cope with this object, a set of indices concept which is used to make bus order list of reactive power injection priority is introduced. A set of indices, based on the overall system conditions, consists of steady state stability index, reactive power transmittance indes, voltage severity index and generator fuel cost index. This scheme and empirical rules of the knowledge on the basis of the human expert result in fast decision-making of the reactive power compensation devices since only the amount of devices is determined by the inference in the knowledge based system when the voltage violation is detected. In this approach, control devices such as shunt capacitor (reactor), transformer tap settings and generator voltages are utilized. Also the developed system herein can be used to minimize control action taken or generator fuel cost according to the user's option on the weighting factor. The results of a case study are also presented.
