Today, in the information society, since the government administration of all countries places importance on clarity and efficiency, the authority concentration of the administration is inevitable. Therefore, the Parliament, which is a legislative body, is at a time when the policy control function to check and monitor it is becoming more important. In particular, due to the emergence of parliamentary democracy, in the reality that the people must elect representatives and represent their own opinions, the parliamentary inspection system is very valuable in that it satisfies the right of the people to know and ultimately enables the people to democratically control the administration. The role of the Parliament moves from the inherent legislative function to the information collection and disclosure of government administration, discussion and resolution of political issues, and observation and supervision of the administration. And it can be seen as the global trend. As a result of this trend, status and role of the National Assembly is being strengthened from the legislative body to the control agency of government administration. Thus, the most substantive authority of Article 61 of the Constitution can be deemed the parliamentary inspection system. The parliamentary inspection system is a system that let exercise the legislation, budget, and authority to control of state administration by identify the challenges and policy implementation of each country's institutions through the audit of the executive administration's overall government administration performance outside the National Assembly. However, due to the amendment of Constitution in 1988, the parliamentary inspection right and investigation of state administration right had reinstated and the parliamentary inspection system, which is being implemented annually, is the 31st year of the year in 2019. However, the general evaluation of the public is negative and insufficient time for inspections, lack of sanctions on nonattendance witnesses, excessive data submission, and refusal to submit materials by the administration were pointed out as the problem. Therefore, in this paper, the researcher tries to point out the overall problems of the parliamentary inspection system and to summarize the effective improvement plans.

챗봇 서비스가 단순 테스크 기능을 벗어나 심리상담, 친구 역할과 같이 사람과 같은 수준의 지능을 가진 강인공지능으로 진화하기 위해 기술적 연구가 활발히 이루어지고 있다. 그러나 실제로 챗봇을 사람으로 인지하기 위해서 일관된 성격을 부여하는 것이 중요함에도 그에 관한 기준이 부재하고 연구 또한 미비하다. 따라서 본 연구는 챗봇의 사용 목적과 사용자 유형에 따라 선호되는 챗봇의 성격에 관해서 연구하였다. 사용 목적은 심심할 때, 심리상담, 테스크(task)로 구분하였고 성격은 DISC이론의 주도형(D), 사교형(I), 신중형(C), 안정형(S)으로 4가지로 구분하였다. 사용자 인터뷰를 통해 사용 목적에 따라 선호하는 챗봇의 나이, 성별, 성격과 심심할 때 챗봇에게 기대하는 콘텐츠 및 말투에 대해서 설문 문항을 도출하였다. 설문한 결과 심심할 때는 주로 사람중심의 성격인 I, S, 테스크 목적일 때는 일 중심 성격인 D,C, 심리상담일 때는 느린 성격인 C,S를 선호하는 것으로 나타났다. 여성은 심리상담을 제외하고 중성을 선호했고 남성은 목적에 상관없이 여성을 선호하였다. 선호하는 연령대는 심심할 때는 또래이거나 어린 나이, 심리상담의 경우 또래이거나 다소 연상, 테스크 목적일 때는 주로 30대가 선호되었다. 심심할 때 기대하는 바에 있어서 대부분의 연령대가 정보를 선호하였지만 20대는 재미가 앞섰고 50-70대는 공감 및 정서적 안정감을 중시하는 것으로 나타났다. 말투에 있어서 20대와 6-70대는 존댓말에 대한 선호가 적지만 3-50대는 존댓말을 선호하였다. 결론적으로 심심할 때는 자신보다 낮은 존재, 테스크 목적일 때는 효율성, 심리상담의 경우에는 신중하게 듣는 태도를 선호하는 경향을 보임을 알 수 있었다. 이러한 결과는 챗봇의 서비스 목적에 따라 적합한 정체성을 설정하는데 유용한 가이드가 될 것으로 기대한다.

Indexing and Retrieving images from large and varied collections using image content as a key is a challenging and important problem in computer vision application. In this paper, a color Content-based Image Retrieval (CBIR) system using hierarchical Region of Interest (ROI) query and indexing is presented. During indexing process, First, The ROIs on every image in the image database are extracted using a region-based image segmentation technique, The JSEG approach is selected to handle this problem in order to create color-texture regions. Then, Color features in form of histogram and correlogram are then extracted from each segmented regions. Finally, The features are stored in the database as the key to retrieve the relevant images. As in the retrieval system, users are allowed to select ROI directly over the sample or user's submission image and the query process then focuses on the content of the selected ROI in order to find those images containing similar regions from the database. The hierarchical region-of-interest query is performed to retrieve the similar images. Two-level search is exploited in this paper. In the first level, the most important regions, usually the large regions at the center of user's query, are used to retrieve images having similar regions using static search. This ensures that we can retrieve all the images having the most important regions. In the second level, all the remaining regions in user's query are used to search from all the retrieved images obtained from the first level. The experimental results using the indexing technique show good retrieval performance over a variety of image collections, also great reduction in the amount of searching time.

A BPO is an irrevocable undertaking given by an Obligor Bank acting on behalf of the buyer to a Recipient Bank acting on behalf of the seller to pay on satisfaction of certain specified conditions. There have been a Trade Service Utility(TSU), a Transaction Matching Application(TMA) and ISO 20022 TSMT messages that core electronic technical systems linked to the BPO. As a key usefulness of the BPO, it brings to market an alternative means of satisfying the risk mitigation, financing and information management needs of banks and businesses engaged in trade. That is, corporates can spread the risk among multiple Obligor Banks by requesting multiple BPOs for the same trade transaction not to exceed the value of the initial transaction. Since the BPO replaces the manual document checking process with the electronic matching of data, buyers and sellers will benefit from significantly increased accuracy and objectivity. By using BPO, buyers and sellers can become trusted counterparties by demonstrating reliability and giving sellers the assurance of being paid on time as per the payment terms and conditions agreed. When compared to L/C, the BPO requires submission of data only. This requires a change of practice of those accustomed to dealing with physical documentation. The beneficiary of a BPO is the Recipient Bank which is always the Seller's Bank. In the meantime, banks will need to agree between themselves that the URBPO 750 will be applied, modified or excluded. However, customers of banks will face low transactional costs due to a fully automated process and standardized data formats used in international trade documentation. There is no amendment and cancellation rules in the URBPO 750s, but only have Assignment of Proceeds rules. As a result, the BPO is likely to enable new business opportunities, lower costs, fast transaction process and strengthen key customer relationships.

Reduced beam section (RBS) moment resisting connections are among the most economical and practical rigid steel connections developed in the aftermath of the 1994 Northridge and the 1995 Kobe earthquakes. Although the performance of RBS connection has been widely studied, this connection has not been subject to in the skewed conditions. In this study, the seismic performance of dogbone connection was investigated at different angles. The Commercial ABAQUS software was used to simulate the samples. The numerical results are first compared with experimental results to verify the accuracy. Nonlinear static analysis with von Mises yield criterion materials and the finite elements method were used to analyze the behavior of the samples The selected Hardening Strain of materials at cyclic loading and monotonic loading were kinematics and isotropic respectively The results show that in addition to reverse twisting of columns, change in beam angle relative to the central axis of the column has little impact on hysteresis response of samples. Any increase in the angle, leads to increased non-elastic resistance. As for Weak panel zone, with increase of the angle between the beam and the column, the initial submission will take place at a later time and at a larger rotation angle in the panel zone and this represents reduced amount of perpendicular force exerted on the column flange. In balanced and strong panel zones, with increase in the angle between the beam and the central axis of the column, the reduced beam section (RBS), reaches the failure limit faster and at a lower rotation angle. In connection of skewed beam, balanced panel zone, due to its good performance in disposition of plasticity process away from connection points and high energy absorption, is the best choice for panel zone. The ratio of maximum moment developed on the column was found to be within 0.84 to 1 plastic anchor point, which shows prevention of brittle fracture in connections.

This paper includes a review of 555 drug-facilitated sexual assault (DFSA) cases analyzed at the National Forensic Service (NFS), South Korea, between 2006 and 2012. The results of toxicological analyses of blood and urine samples were also reported, and furthermore the results were interpreted with respect to the number of drugs detected. The number of DFSA cases was highest during warmer summer months and the mean age of the victims was 25 years, with 48% being between 20 and 29 years. Accommodations or entertainment places were the most frequent place of the sexual assault (57%); and the assailant was a stranger in 72% of the DFSA cases. Drugs were identified in the blood or urine samples in 145 cases (26%) and sedative-hypnotics, such as benzodiazepines and zolpidem, were the most commonly detected, along with sedative antihistamines such as doxylamine and diphenhydramine. The frequent presence of sedative drugs in biological samples tends to implicate their use in chemical submission. However, interpreting the analytical results in terms of voluntary vs. surreptitious administration of drugs requires further detailed investigation and knowledge of the victim's health status and medication used at the time of event.

The 'discovery' or 'conquest' of the New World in 1492 was the starting point of world history that irrevocably changed the fate of the Latin American continent. The global stream known as 'Columbian Exchange', which was the widespread inter-continental contacts, inter-civilizational conflicts, or bilateral communication, has rendered multifarious effects throughout many historical periods up to the very contemporary time. The propagation of Catholicism initiated along with this 'discovery' transformed Latin America of nowadays in the region that has the biggest Catholic population in the world. The previous studies in Korea regarding Latin American Catholicism has focused on the spread of Catholicism in relation to the European colonization, rather than analyzing the concrete and detailed ways in which Catholicism exerted tremendous influences in the whole continent. They were less attentive to various historical contexts in which the diffusion of Catholicism differed greatly according to cultural landscapes and political specificities. Thus, this essay attempts to examine the diffusion of Catholicism from the perspective of confrontation between royal authorities and the power of church. The essay points out that the royal communities and institutional authorities which facilitated the intial process of Catholic evangelization maintained antagonistic relationship with ecclesial powers. By delving into the gradual transformation of church systems, it reveals that Catholicism in Latin America became a major field for conquerors in power to attain economic and political dominance. And unlike the initial submission and hospitality, the religious convert of the indigenous people attested to the violent inhumanity and opposition. Therefore, the essay aims to pave a clearer way to the understanding of complicated dynamics and conflicts between Catholicism in Latin America and the establishment of Spanish colonization.
