최근 미 연준이 정책금리 인하를 결정하면서 향후 통화정책 운용방향에 관해 관심이 고조되고 있다. 과거 금리동결 시점이나 동결기간 중, 그리고 인상이나 인하 시점이 다가왔을 때 통화정책 의결문의 표현을 살펴보면 단어 선택의 변화 등을 통해 시장과 꾸준하게 커뮤니케이션해 왔었다는 것을 알 수 있다. 하지만 이렇게 의결문의 표현을 문맥을 통해 분석하는 방법이 다소 주관적이고 정성적인 분석에 그칠 수 있다는 비판이 있다. 이런 점을 고려하여 Woo와 Chang (2016)에서는 데이터마이닝 기법 중 하나인 텍스트마이닝 방법을 통해 의결문 분석 과정을 보완할 수 있는 방법을 제안한 바 있다. 본 논문에서는 선행 연구 결과를 토대로 미 연준의 통화정책 의결문의 정책 시그널링 효과를 평가해 보았다. 의결문의 특성을 텍스트마이닝 관점에서 분석하고 의결문 간 표현의 변화를 포착하여 향후 정책 기조 변화를 예측하고자 하였다. 이를 위해 대표적인 데이터마이닝 기법인 의사결정나무모형과 신경망모형을 사용하였다. 분석 결과, 대체로 의결문 간 비유사성의 변화가 향후 정책 변화를 효과적으로 예측할 수 있는 것으로 평가되었으며, 그동안 미 연준이 의결문을 통해 체계적으로 정책 시그널링을 실시해 온 결과로 판단할 수 있다.

This study aimed to explain the factors that influenced an individual's decision to migrate. The method of analysis in this study was the estimation of the probit regression model with data from the Indonesian Family Life Survey (IFLS-5), which covered 30,000 individuals from 13 provinces in Indonesia. Data from IFLS-5 were longitudinal data, meaning that the study was looking for data consistently to get reliable data from respondents. The research variables to determine the individual's decision to migrate were education level, income level, employment status, marital status, land ownership status, health quality, gender, residence status, and poverty status. Individual decision to migrate as a dependent variable was placed as a dummy variable. The results showed that the level of education, income level, employment status, marital status, land ownership status, health quality, and poverty status significantly influenced an individual's decision to migrate. Meanwhile, gender and residence status did not significantly affect an individual's decision to migrate. This research recommends that it is necessary to pursue a policy of economic equality between regions because economic factors are the main trigger for an individual's decision to migrate. Policies to overcome economic disparities among regions will reduce the individual's decision to migrate.

Access control has always been one of the effective methods to protect data security. However, in new computing environments such as big data, data resources have the characteristics of distributed cross-domain sharing, massive and dynamic. Traditional access control mechanisms are difficult to meet the security needs. This paper proposes CACM-MMSR to solve distributed cross-domain access control problem for massive resources. The method uses blockchain and smart contracts as a link between different security domains. A permission decision model migration method based on access control logs is designed. It can realize the migration of historical policy to solve the problems of access control heterogeneity among different security domains and the updating of the old and new policies in the same security domain. Meanwhile, a semantic reasoning-based permission decision method for unstructured text data is designed. It can achieve a flexible permission decision by similarity thresholding. Experimental results show that the proposed method can reduce the decision time cost of distributed access control to less than 28.7% of a single node. The permission decision model migration method has a high decision accuracy of 97.4%. The semantic reasoning-based permission decision method is optimal to other reference methods in vectorization and index time cost.

To collect data trained staff conducted person-to-person interviews with the assistance of structured questionnaires. The questionnaires cover the areas of life style pattern study. the characteristics of demographic sociology, decision-making process related to the use of medical service. The influencing factors were analyzed and as a result total 18 factors were singled out. Cluster analysis was performed to differentiate similar responses. Each group was named as 'health-unconcern type' 'passive health-concern type' 'regular health-concern type' and 'active health-concern type' according to the characteristics. Each group showed statistically significant difference in the characteristics of demographic sociology. Decision-making process regarding the use of medical service according to lifestyle was analyzed. As a result following items showed significant difference:whether the information was utilized, what was the criteria in selecting medical facilities for serious illness or complicated examination. who was the decision maker in selection medical facilities, and with whom one discussed in selecting medical facilities. The result of this study has its limitation in that it can not be applied directly to market subdivision. However, this will help medical facilities understand customers' lifestyle. which will eventually provide medical facilities with marketing tools in establishing effective PR strategy. In order to apply the lifestyle as a marketing tool of medical facilities, following tasks are to be carried out: the development of the questionnaire which can better analyze consumers' lifestyle related to the use of medical service. the examination of precise characteristics of subdivided market according to lifestyle. and the continuing study on the relationship between lifestyle and the process in selecting medical facilities.

This study was conducted to get a resonable set of budget allocation to public health programs. Matrix Delphi technique was used to obtain the logic of study results and eventually to form a human model which could predict opinion of professionals on budget allocation. Thirty-two professionals in academic and governmental area responded to Delphi survey. Questionnaire was developed using matrix formation, and the matrix was formed by 6 decision criteria on budget allocation and 26 public health programs. The decision criteria are as following: size of problem(morbidity), severity of problem, social equity, importance of prevention, technical feasibility and efficiency of programs. Severity of problem dropped out of the model because it had significant correlation with the size of problem. A total score of each program was obtained by weighting the relative importance of each criteria which also were given by survey respondents. These total scores indicate that the most important public health program is vaccination for infants and children in terms of budget allocation. Monitoring communicable diseases, mental health program, and anti-smoking program are the next. In addition, respondents were asked of the desirable budget size of each program. The result was rearranged by multiple regression model using the scores of each decision criteria. In this process, the current budget size of central government was provided to the respondents, and included in the model. h set of desirable budgets modified using tile model was obtained. Considering the current size of budget, tile results of the model is very different from that of the total score. Managing dementia is ranked the first. Health promotion program for the elderly, rehabilitation of the disabled and monitoring communicable diseases are the next. The need to increase the budget of vaccination for the infants and children was not found as so high. The matrix structure in Delphi survey gave us the precise basis to make optimal decision, and made it possible to develop an opinion predicting model. However the plentifulness and diversity of professional opinions were not fully obtained due to the limited number of decision criteria.

Private land within national parks has raised acute questions for impact assessment practitioners as to whether it is ecologically resourceful enough to be conserved or whether it should be removed from national parks and compensated accordingly. The purpose of this study is to provide a framework for spatial decision support through assessing ecological resource of private land within national parks. In order to assess the ecological resource, private land within national parks was analyzed and quantified based upon topography, flora and fauna. National parks, according to the ecological resource assessment, have been divided into three groups : the parks in need of careful attention for conservation; the parks needed to be retained as buffers, and; the parks that can be released to private land. According to the analysis, part of Mountain Joowang is the third-tier land that does not require conservation efforts. This case study intends to help policy-makers decide whether some private land within national parks can be released and, after the release, what should be done to prevent reckless development of the released land.
