To search based on the functional classification or provenance is not easy for users, and the key word-based information retrieval presents only simple words matching with the title of the records. The Presidential Archive of Korea developed a subject classification scheme to improve the convenience of searching for various records and came up with a subject thesaurus based on the scheme that utilizes the terms appearing on the title of the records and the terms used by the users who searched the portal or requested information disclosure. This research presents the development process of subject thesaurus. It also presents the utilization methods for records management work and services.

Some issues and solutions considered for the various situations that we faced in the process of developing guidelines of thesaurus construction are described in this paper. There were many proper names and proper nouns among the terms considered in the process. The thesaurus needed to include a function of an authority file. Preferred terms were selected based on what the university's official records would use. The scope of the proper names for inclusion was the people who held official positions in the university and the people who were the subject of the materials. However, when the system allows synthesized retrieval of the field of creator and donor, inclusion of too many names were considered unnecessary.

The middle aged women in their 40s and 50s were the subjects for this study. There were 6 women for the group of complex exercise. There were 6 women for the group of complex exercise and intake of peony beverage. There were 5 women for controlled group. This study compares and analyzes the effect of complex exercise program, in which the subjects exercise 60 minutes a day for three times a week, on the physical structure, inflammation factors and metabolic syndrome of middle aged women. The result is as shown in the following. there were significant difference (p<.001) for fibrinogen of each group in the change of inflammation factors due to regular complex exercise program and intake of peony beverage. But there were not significant difference in the period, period x the effect of groups' interaction. It is believed that there could be polluted variables, as the number of subjects for this study is not enough. So there should be a study that has more subjects to make it more significant.

Since the 1990s, the growth of the public library program field progressed rapidly at home and aborad as the proportion of programs increased as a major job for public libraries in response to social changes and user demands. However, it is difficult to find a study to grasp the overall research trend in the field of public library programs in Korea. Accordingly, intellectual structure analysis was performed based on keyword profiling to examine research trends in the domestic public library program field. In particular, keyword analysis, network analysis and cluster analysis, and period/year analysis were performed step by step based on the author keywords (uncontrolled keywords) of degree papers and academic journals retrieved from the RISS database. In addition, based on the results of this intellectual structure analysis, the research trends of public library programs were comprehensively reviewed and future research tasks were presented.

만경강 유역은 우리나라의 농업지역 중 하나로 많은 농업용수를 필요로 하는 지역으로 농업용수 공급을 위하여 다수의 취입보가 설치되어 있으며, 충분한 농업용수 확보를 위하여 다른 지역과 달리 가동보와 고정보가 병설로 설치되어 있는 곳이 많다. 통상적인 가동보는 농업용수 확보와 공급을 위하여 농번기인 4월~9월까지 운영되는 것이 일반적이며, 이러한 가동보 운영으로 인하여 다양한 수위-유량관계의 변동성이 발생한다. '20년부터 전주천에 위치한 취입보는 과거와 달리 기존의 월류 높이가 높은 보의 형태에서 어도가 넓고, 보의 높이가 낮은 친환경 월류보의 형태로 전환이 이루어지고 있으며, 그 영향으로 인하여 과거의 수위-유량관계와는 상이한 결과가 발생한다. 하도의 변동성은 단면 측량 등으로 확인 할 수 있으나, 가동보 운영과 공사와 같이 통제특성에 의한 변동사항이 발생하는 경우 모니터링이 필수적이다. 본 연구에서는 만경강 유역에 위치한 전주시(미산교)관측소를 대상관측소로 선정하였으며, 대상관측소는 '20년 12월~'22년 1월까지 친환경 월류보 전환을 위하여 가동보 운영과 공사가 진행된 관측소이다. '20년 12월 친환경 월류보 형태의 전환을 위하여 가동보 운영을 시작하였으며, '21년은 1월~3월은 유지유량을 위한 가동보 운영을 실시하였으며, 4월~9월은 농업용수 확보를 위한 가동보 운영을 실시하였고, 10월~12월은 하도 내 공사 진행에 따라 가동보와 고정보를 같이 운영하였다. 이 기간동안 가동보와 고정보 모니터링을 실시하였으며, 정확한 유량측정성과와 곡선식 확인을 위하여 동일한 위치에서 측정을 수행하였다. 가동보 운영과 공사영향 모니터링 결과와 유량측정성과를 바탕으로 수위-유량관계 변화를 분석하였으며, 저수위 구간은 가동보 운영에 따라 총 11차례 기간분리가 발생하였으며, 중수위 구간도 가동보 운영으로 인하여 과거와 상이한 경향이 발생하여 곡선식을 재개발 하였다. 결과적으로 본 연구에서는 가동보 운영에 따른 다수의 유량측정성과를 확보하였으며, 확보한 유량측정성과의 분석을 통한 신뢰도 높은 수위-유량관계곡선식을 개발하였고 이를 통해 생산된 유량자료는 정확도가 매우 높은 것으로 분석되었다.

In the midst of the development of science and technology based on the 4th industrial revolution, the ROK Army is moving forward with the ARMY TIGER 4.0 system, a ground combat system that combines future advanced science and technology. The system is developing around an AI-based hyper-connected ground combat system, and has mobility, intelligence, and networking as core concepts. Especially, the dronebot combat system is used as a compound word that refers to unmanned combat systems including drones and ground unmanned systems. In future battlefields, it is expected that the use of unmanned and artificial intelligence-based weapon systems will increase. During the transition to a complete unmanned system, it is a very important issue to ensure connectivity individual unmanned systems themselves or between manned and unmanned systems on the battlefield. This paper introduces the Multiplexer Allocation Problem (MAP) for effective command control and communication of UAV/UGV, and proposes a heuristic algorithm. In addition, the performance of the proposed algorithm is analyzed by comparing the solutions and computing time. Also, we discuss future research area for the MAP.

This study aims to discuss ways to improve the information disclosure system centered on the Freedom of Information Act by analyzing the revision history of the Act and interviewing information disclosure experts. First, the study analyzed the revision history and contents of the Act from its enactment to today. It found that although positive amendments have been made in terms of expanding the right to know, they have been limited to operational aspects, and no amendments have been made to the criteria for determining information subject to disclosure. The interview was organized into three areas: achievements, problems, and improvements of the Act. The analysis was conducted by breaking down the content of each area and organizing it into themes. In conclusion, the study proposed eight recommendations for improvement, including expanding the scope of information disclosure, categorizing the information to be disclosed, securing a procedure for appealing the non-disclosure of information, increasing the effectiveness of the committee, introducing penalties and disciplinary regulations, establishing an Information Disclosure Appeals Tribunal, establishing systematic controls to prevent misuse of the right to request information, and merging the Public Data Act with the Freedom of Information Act.

The freedom of assembly is the fundamental freedoms guaranteed by the Constitution. However, as far as our reality is concerned, the freedom of assembly is guaranteed only when it is under the control of the police, and otherwise it is perceived as an object to be suppressed. Police say even that they will not tolerate even a small illegal law while referring to the "broken window theory". Therefore, regardless of the peaceful nature of the rally, it is too obsessed with 'compliance'. This attitude is causing the citizens who participated in the assembly to be put to the object to be suppressed. This paper analyzes the requirements and current status of police force, focusing on the vehicle-wall-blocking and water cannon as a means of using the police force, which is a recent problem, and suggests ways to improve it. First of all, the installation of the wall cuts off the essential communication function of the assembly by separating the meeting place from the object of protest. Thus, despite the warning for prevention in the face of illegal acts, other than installing a barrier, it should be allowed only in the 'urgent case where there is a risk of causing damage to the life, body or property of the person'. Without this urgency, the vehicle-wall-blocking should not be allowed to be proactive as well as preventive. Secondly, the water cannon is a police force that is likely to harm people's life and body. Therefore, aiming shots, which could pose a significant risk to the human body, should in principle be prohibited. However, considering its risk, it should be supplementary used only when there is no other alternative, only when the direct risk to the legal interest of the other person or the order of public well-being is 'obvious'. In addition, as for the use standard of such a thing, it is necessary to be specified by law.

Seasonal influenza epidemics cause 3 to 5 millions severe illness and 250,000 to 500,000 deaths worldwide each year. To prepare better controls on severe influenza epidemics, many studies have been proposed to achieve near real-time surveillance of the spread of influenza. Korea CDC publishes clinical data of influenza epidemics on a weekly basis typically with a 1-2-week reporting lag. To provide faster detection of epidemics, recently approaches using unofficial data such as news reports, social media, and search queries are suggested. Collection of such data is cheap in cost and is realized in near real-time. This research aims to develop regression models for early detecting the outbreak of the seasonal influenza epidemics in Korea with keyword query information provided from the Naver (Korean representative portal site) trend services for PC and mobile device. We selected 20 key words likely to have strong correlations with influenza-like illness (ILI) based on literature review and proposed a logistic regression model and a multiple regression model to predict the outbreak of ILI. With respect of model fitness, the multiple regression model shows better results than logistic regression model. Also we find that a mobile-based regression model is better than PC-based regression model in estimating ILI percentages.

A series of coffee middlemen has come to be regarded as an exploitative force in the lives of small and poor coffee farmers, which is called 'coyote', controlling production, paying unfair prices for labor and goods, and participating in fraudulent practices to maximize their own profits. However, the reality of gains captured by coffee middlemen in the value chain might be exaggerated and even unfair. Therefore, the main aim of this paper is to reconsider the implication of coffee middlemen for the development of coffee value chain in Vietnam. It also attempts to identify their characteristics by investigating relations among coffee farmers, middlemen and processing/exporting firms. In terms of middlemen's margin in the coffee sub-sector, their margin is quite small when compared to other actors higher in the value chain. Rather, coffee middlemen in Vietnam have played a critical role as an intermediary of change in local economies. More specifically, coffee middlemen in Dak Lak has played a significant role as a market facilitator by stimulating the access of farmers to markets by providing buyers for farmers thanks to changes in institutional environment. Also, they have played a critical role as an agent of sustainable coffee production by encouraging sustainable coffee production in accordance with the demand of processing and exporting firms.
