As social disasters occur under the Disaster Management Act, which can damage the people's "life, body, and property" due to the rapid spread and spread of unexpected COVID-19 infectious diseases in 2020, information collected through inspection and reporting of infectious disease pathogens (Article 11), epidemiological investigation (Article 18), epidemiological investigation for vaccination (Article 29), artificial technology, and prevention policy Decision), (3) It was used as an important basis for decision-making in the context of an infectious disease crisis, such as promoting vaccination and understanding the current status of damage. In addition, medical policy decisions using infectious disease data contribute to quarantine policy decisions, information provision, drug development, and research technology development, and interest in the legal scope and limitations of using infectious disease data has increased worldwide. The use of infectious disease data can be classified for the purpose of spreading and blocking infectious diseases, prevention, management, and treatment of infectious diseases, and the use of information will be more widely made in the context of an infectious disease crisis. In particular, as the serious stage of the Disaster Management Act continues, the processing of personal identification information and sensitive information becomes an important issue. Information on "medical records, vaccination drugs, vaccination, underlying diseases, health rankings, long-term care recognition grades, pregnancy, etc." needs to be interpreted. In the case of "prevention, management, and treatment of infectious diseases", it is difficult to clearly define the concept of medical practicesThe types of actions are judged based on "legislative purposes, academic principles, expertise, and social norms," but the balance of legal interests should be based on the need for data use in quarantine policies and urgent judgment in public health crises. Specifically, the speed and degree of transmission of infectious diseases in a crisis, whether the purpose can be achieved without processing sensitive information, whether it unfairly violates the interests of third parties or information subjects, and the effectiveness of introducing quarantine policies through processing sensitive information can be used as major evaluation factors. On the other hand, the collection, provision, and use of infectious disease data for research purposes will be used through pseudonym processing under the Personal Information Protection Act, consent under the Bioethics Act and deliberation by the Institutional Bioethics Committee, and data provision deliberation committee. Therefore, the use of research purposes is recognized as long as procedural validity is secured as it is reviewed by the pseudonym processing and data review committee, the consent of the information subject, and the institutional bioethics review committee. However, the burden on research managers should be reduced by clarifying the pseudonymization or anonymization procedures, the introduction or consent procedures of the comprehensive consent system and the opt-out system should be clearly prepared, and the procedure for re-identifying or securing security that may arise from technological development should be clearly defined.

Traffic jam densified day by day is phenomenon to occur lack of the road capacity in comparison with traffic density, but lack of the road cannot be concluded by main cause of traffic ism. Because the central function of a city would be concentrated upon the downtown and traffic demand would not be evenly distributed by the classification of an hour. Therefore, this study based on the fact that each driver will select the route generating traffic delay very low when path choice from origin to destination in travel plan estimating the quality of passage could be maintained the speed he want will approach to a characteristic grasp of a road, traffic, driver changing every moment by traffic-demand of road increased as a geometrical series with analysis a classification of a street, a intersection along the path on traffic density and highway capacity analysis the path using GIS techniques about complex street network, also will get the path of actual optimum for traffic delay trend creating under various condition the classification per a hour, a day of week and an incident through network such as analysis for traffic generation zone adjacent about street, intersection, afterward will expect the result increasing efficiency of the road-use through a good distribution of traffic by optimum-path choice, accordingly will prepare the scientific, objective, appropriate basis to decide the reasonable time of a road-widen and expansion through section analysis along a rate of traffic volume vs. road capacity.

The shift to the digital media era is increasing the importance of the ability to accept, produce and share news through digital media(news literacy), but there is a lack of diagnosis of the level of news literacy among Korean adults and discussions on how to improve news literacy. This study analyzed the news literacy level of Korean adults according to background variables (urbanization degree, gender, age, academic background) and examined the relationship between the amount of news literacy-related practices and the level of news literacy. The results showed that the overall level of news literacy among adults in Korea was not high and that differences between groups were also statistically significant. The significant relevance between the amount of news literacy-related practices and the level of news literacy has also been identified. Based on the findings, it was suggested that the need for policy support to improve news literacy among Korean adults, the need to prioritize the resources of news literacy education according to background variables of adult learners, and the need to continuously monitor news literacy levels of Korean adults.

Long Term rental housing, which is supplied for performing housing welfare, has been aging from permanent rental housing. Therefore, variety housing welfare projects are planing and performing for improving aged facilities. However, although every welfare policy are necessary, we have to efficiently allocate and commit the funds, because the fund and resources is limited. And there is required the feasibility study before performing public project for housing welfare, because it needs large amount of financial supports by government. Meanwhile, because most of existed studies are focused on guide development, it has limitation to apply the result of existed studies in this study, which considers public remodeling project for housing welfare. But in reality, public project is been decided by willing of policy decision-maker. Therefore, in this study, we suggest the evaluation method of policy value for two alternatives(remodeling and maintain) of a aged long term rental housing. To extract the attributes of policy value, we considered categorized items of preliminary feasibility study. Through extracting attribute factors of policy value for aged long term rental housing, we can calculate the policy value of remodeling and maintain alternatives by using MAUT. As a result of analysis, we can find that the utility value of remodeling is 0.6161 and the utility value of maintain is 0.2461 and also the utility of remodeling is higher than utility of maintain. Therefore, when we plan the public projects for performing housing welfare, we can choose remodeling alternative rather than maintain alternative using quantitive data.

In this paper, we propose a new distributed Alamouti space-time block coding scheme using cooperative relay system composed of one source node, three relay nodes and one destination node. The source node is assumed to be equipped with two antennas which respectively use a 2-beam array to communicate with two nodes selected from the three relay nodes. During the first time slot, the two signals which respectively were transmitted by one antenna at the source, are selected by one relay node, added, amplified, and forwarded to the destination. During the second time slot, the other two relay nodes implement the conjugate and minusconjugate operations to the two received signals, respectively, each in turn is amplified and forwarded to the destination node. This transmission scheme represents a new distributed Alamouti space-time block code that can be constructed at the relay-destination channel. Through an equivalent matrix expression of symbols, we analyze the performance of this proposed space-time block code in terms of the chernoff upper bound pairwise error probability (PEP). In addition, we evaluate the effect of the coefficient $\alpha$ ($0{\leq}{\alpha}{\leq}1$) determined by power allocation between the two antennas at the source on the received signal performance. Through computer simulation, we show that the received signals at the three relays have same variance only when the value of $\alpha$ is equal to $\frac{2}{3}$, as a consequence, a better performance is obtained at the destination. These analysis results show that the proposed scheme outperforms conventional proposed schemes in terms of diversity gain, PEP and the complexity of relay nodes.

In this study the factors of fire damage are analyzed through previous research reviews. Local environmental factors as well as those factors attributed to fire damage (number of fire events, number of injured, number of death, economic loss) were selected to compose mutual relationship model. In order to verify this relationship model, official statistics concerning fire damage were collected from 228 local governments and compared with results from previous research. As a result of this comparison four dependent variables and 22 independent variables that affect fire damage were analyzed. Independent variables are divided into human vulnerability factors, physical vulnerability factors, economic vulnerability factors, mitigating factors and local characteristics. To analyze a relationship between selected dependent variables and independent variables, we applied a semi-logarithm model and performed regression analysis. Among the 22 independent variables, the number of the weak to disaster, social welfare service workers, workers in manufacturing industry, and the number of workers in restaurants and bars per 10,000 people show the significant correlation with the number of fire incidence. The number of death from fire is significantly related to two variables which are the number of social welfare service workers per 10,000 and the ratio of commercial area. Damage cost is significantly dependent on the property taxes per 10,000 people. These factors were included in the research model as vulnerability factors (human, physical, economic) and mitigating factors and local characteristics, and the validity of research model was verified. The result could contribute to fire-fighting resource allocation in Korea or they can be utilized in establishing fire prevention policy, which will enhance the national level of fire safety.

Last-Mile delivery optimization plays a key role in the urban supply chain operation, which is the most expensive and time-consuming and most complicated part of the whole delivery process. The urban consolidation center (UCC) is regarded as a significant asset for supporting customer demand in the last-mile delivery service. It is the key benefit of UCC to improve the load balance of vehicles and to reduce the total traveling distance by finding the better route with the well-organized multi-leg vehicle journey in the urban area. This paper presents the model using multiple scenario analysis integrated with mathematical optimization techniques using Geographic Information System (GIS). The model aims to find the best solution for the distribution network consisted of DC and UCC, which is applied to the case of Ulaanbaatar Mongolia. The proposed methodology integrates two sub-models, location-allocation model and vehicle routing problem. The multiple scenarios devised by selecting locations of UCC are compared considering the general performance and delivery patterns together. It has been adopted to make better decisions the quantitative metrics such as the economic value of capital cost, operating cost, and balance of using available resources. The result of this research may help the manager or public authorities who should design the distribution network for the last mile delivery service optimization using UCC within the urban area.

Recently, Korea has faced a change in the pattern of water use due to urbanization, which has caused difficulties in understanding the rainfall-runoff process and optimizing the allocation of available water resources. In this perspective, spatially downscaled analysis of the water balance is required for the efficient operation of water resources in the National Water Management Plan and the River Basin Water Resource Management Plan. However, the existing water balance analysis does not fully consider water circulation and availability in the basin, thus, the obtained results provide limited information in terms of decision making. This study aims at developing a novel water circulation analysis model that is designed to support a quasi-real-time assessment of water availability along the river. The water circulation model proposed in this study improved the problems that appear in the existing water balance analysis. More importantly, the results showed a significant improvement over the existing model, especially in the low flow simulation. The proposed modeling framework is expected to provide primary information for more realistic hydrological drought monitoring and drought countermeasures by providing streamflow information in quasi-real-time through a more accurate natural flow estimation approach with highly complex network.

산업화에 따른 온실가스 배출량 증가는 심각한 기후변화의 요인으로 작용하여 우리나라를 포함한 전세계는 이에 대응하고자 노력하고 있다. 지구온난화 및 엘리뇨 현상 등으로 인하여 가뭄, 홍수, 한파, 혹서 등의 재해와 기상이변이 속출하고, 최근 우리나라의 경우 매년 가뭄이 발생하고 있어 이에 대한 대책이 시급한 실정이다. 이에 가뭄의 대처방안에 대한 관심이 증대 되었고, 가뭄을 정량적으로 하는 연구들과 기후변화에 따른 가뭄 취약성 평가에 대한 연구들이 진행 되었다. 가뭄의 취약성 평가는 기후변화에 따른 가뭄 저감을 위한 목적에 따라 평가목적, 평가방법, 필요한 정보, 과정의 설계 불확실성에 대한 고려 등이 달라진다. 취약성 평가의 목적은 크게 기후영향평가, 적응정책의 자원배분을 위한 취약부문 및 지역 파악, 적응정책 개발을 위한 적응 대안 분석으로 나눌 수 있다. 취약성 평가의 목적이 취약성 유발요인에 관한 정보를 제공하여 어디에 적응 대책에 필요하고 효과적일 수 있는지 파악하는데 도움을 주는 것이라면, 취약성 결정요인에 대한 분석을 명료하고 상세하게 수행하는 것이 중요하다. 본 연구에서는 기후변화에 따른 농업용수의 취약성 평가지표를 개발하기 위하여 국내 외 취약성 평가 지표를 분석, 국내 농업기상 및 농업용수 등 관련 자료(1981 ~ 2015)의 조사 현황을 고려하여 취약성 평가지표(강우량, 증발산량, 경지면적, 저수용량, 용수로 통수능력, 수요량, 하천평수위)를 제시하고 국내 농업기상 및 농업용수 등 관련 자료의 조사 현황을 고려하여 대상지구인 충북 진천 무수 관개지구에 취약성 지표를 적용하였다. 강우의 증가는 가뭄 취약성에 긍정적 영향을 나타냈고, 증발산량의 증가는 부정적인 영향을 나타냈다. 경지면적의 감소는 소비수량이 증가하므로 가뭄 취약성에 긍정적인 영향을 나타냈고, 저수 용량의 감소는 홍수조절능력의 저하로 인해 부정적인 영향을 끼치고, 하천 홍수위의 변화는 가뭄에 영향을 미치는 요소 중의 하나로 홍수위가 높아지면 가뭄에 부정적인 영향을 나타냈다. 가뭄 취약성 지표들을 각각의 가중치를 합산한 결과, 1981년~2015(5년 분할) 무수지구의 가뭄 취약성 평가는 분석을 시작한 1981년부터 2015년 까지 안전과 우려가 반복 되는 것으로 나타났다. 연구대상지구의 농업기상 및 관련 자료들의 조사 기간이 길면 빈도별 신뢰성이 높아진다. 따라서 자료의 누적은 정확한 기후변화에 대한 이수 및 치수 취약성 평가 지표개발 및 평가 능력을 높여 줄 수 있을 것으로 판단된다.

This study aimed to determine the importance of the policies formulated through the Ministry of Maritime Affairs and Fisheries' master plan for Seafarer's policy. To confirm the importance of the Seafarer's policy, AHP analysis was conducted on the 3 main policies and 15 auxiliary policies established by the master plan for Seafarer's policy. To analyze the reliability of the survey, we investigated the inconsistency ratio of 34 respondents retrieved. We found that 25 respondents validated the reliability of the findings. The analysis showed that the policy of establishing a stable supply and demand system was the most important among the main policies for seafarers, while the policy of fostering seafarers linked to jobs was the most important one among the auxiliary policies. By group, the government recognized establishing a stable supply and demand system as a priority of policy. Dif erences were found on the fact that improving working conditions and expanding welfare were important for seafarers. This study, which analyzed the importance of the Seafarer's policy through AHP analysis, has the following implications. We established guidelines to enhance efficiency, such as budget allocation by policy according to the importance in implementing Seafarer's policies. Furthermore, our study can be used as basic data for establishing a master plan for Seafarer's policy by comparing differences in importance per group.
