This study focuses on the vulnerability of our society and environment under the Covid-19 pandemic. The medical descriptions about severe acute respiratory syndrome coronavirus disease 2019 provide the serious manifestation of the SARS-CoV-2 virus and a new resilient hope of its vaccination. Moreover, with the perspective of feminist practical theology, the author explores a resilient possibility to reconstitute an ecological relationship between our society and environment. In addition, many people's depression in the time of Covid-19 is understood in the meaningful narrative of the relationship between integrity and despair to be stressed by Erikson in the perspective of Loder. Especially, this study focuses on the main stream of designing the convergence curriculum of medicine and theology to move toward the life wellbeing of community members, overcoming their difficult circumstances such as Covid-19.

The jurisprudential legal rules govern the way Muslims react and interact to daily life. This creates a huge stream of questions, that require highly qualified and well-educated individuals, called Muftis. With Muslims representing almost 25% of the planet population, and the scarcity of qualified Muftis, this creates a demand supply problem calling for Automation solutions. This motivates the application of Artificial Intelligence (AI) to solve this problem, which requires a well-designed Question-Answering (QA) system to solve it. In this work, we propose a QA system, based on retrieval augmented generative transformer model for jurisprudential legal question. The main idea in the proposed architecture is the leverage of both state-of-the art transformer models, and the existing knowledge base of legal sources and question-answers. With the sensitivity of the domain in mind, due to its importance in Muslims daily lives, our design balances between exploitation of knowledge bases, and exploration provided by the generative transformer models. We collect a custom data set of 850,000 entries, that includes the question, answer, and category of the question. Our evaluation methodology is based on both quantitative and qualitative methods. We use metrics like BERTScore and METEOR to evaluate the precision and recall of the system. We also provide many qualitative results that show the quality of the generated answers, and how relevant they are to the asked questions.

Modern supply chains include multiple activities from collecting raw materials to transferring final products. These activities involve many parties who share a huge amount of valuable data, which makes managing supply chain systems a challenging task. Current supply chain management (SCM) systems adopt digital technologies such as the Internet of Things (IoT) and blockchain for optimization purposes. Although these technologies can significantly enhance SCM systems, they have their own limitations that directly affect SCM systems. Security, performance, and scalability are essential components of SCM systems. Yet, confidentiality and scalability are one of blockchain's main limitations. Moreover, IoT devices are lightweight and have limited power and storage. These limitations should be considered when developing blockchain-based IoT-SCM systems. In this paper, the requirements of efficient supply chain systems are analyzed and the role of both IoT and blockchain technologies in providing each requirement are discussed. The limitations of blockchain and the challenges of IoT integration are investigated. The limitations of current literature in the same field are identified, and a secure and scalable blockchain-based IoT-SCM system is proposed. The proposed solution employs a Hyperledger fabric blockchain platform and tackles confidentiality by implementing private data collection to achieve confidentiality without decreasing performance. Moreover, the proposed framework integrates IoT data to stream live data without consuming its limited resources and implements a dualstorge model to support supply chain scalability. The proposed framework is evaluated in terms of security, throughput, and latency. The results demonstrate that the proposed framework maintains confidentiality, integrity, and availability of on-chain and off-chain supply chain data. It achieved better performance through 31.2% and 18% increases in read operation throughput and write operation throughput, respectively. Furthermore, it decreased the write operation latency by 83.3%.

하천 합류부는 서로 다른 지형학적 특성과 수리학적 특성을 가지는 두 개의 하천이 하나로 합쳐지는 구간으로 급격한 흐름의 변화 및 퇴적물의 유입과 수리학적 지형변화가 발생하는 구간이다. 합류부 구간에서는 물질의 종류 또는 온도차로 인해 밀도 차이로 유체의 흐름이 발생하게 되는데 이것을 밀도류라고 한다. 밀도차이에 의해 성층이 생긴 수체혼합거동을 파악하기 위해서는 본류 및 지류의 일정 구간을 포함하는 합류부 구간에 대한 정밀한 계측 및 관찰이 필요하다. 이러한 수체 혼합에 대한 종합적인 분석은 유속장 및 유량정보를 취득하여 파악할 수 있지만, 성층류가 흐르는 하천의 서로 상이한 물리적 특성과 수질특성을 가지는 수체의 혼합양상 및 그에 따른 물질혼합양상을 파악하는데 한계가 있다. 따라서 본 연구에서는 합류부 구간에서의 수온 분포를 통하여 밀도류를 파악하고자 한다. 하천의 광범위한 데이터 중 연직 자료와 수표면 자료를 취득하였고, 이를 통해 합류부의 성층현상을 확인하고자 하였다. ADCP를 보트 측면에 설치하여 저속운행으로 수리량을 측정하는 방식과 YSI를 이용해 측선설치 없이 측선 선정 후 보트를 이용하여 흐름에 직각인 방향으로 이동하며 실시간 농도를 측정하는 방식으로 얻은 연직자료 중 수온, EC 등의 직독식 센서 데이터 값을 사용하여 수온차에 따른 수체혼합 패턴을 분석하여 합류부의 혼합 양상을 분석 하고자 하였다. 본 연구에서는 기존 수질측정의 한계였던 1차원적인 측정결과가 나타내는 분석결과를 2차원적으로 보완이 가능하며, 비교 분석한 결과를 토대로 밀도류에 따른 혼합양상 결과가 지니는 혼합패턴을 분석한다면 향후 하천 하류구간의 취수장 취수 시스템에 많은 도움을 줄 뿐만 아니라 합류부 구간의 혼합패턴에 따라 수층 내 성층구간의 현황조사 및 혼합특성 파악을 통해 관리방안제시에 사용될 것으로 사료된다.

'In-Jon(人尊)' is one of a concept which constitute the mainstay of Daesoon thought. To be superficial, the concept is appeared to be limited at a area of anthropology, but In-Jon is a large concept which includes ontology and epistemology. Because the essence of human being is connected with God and the such possibility is related to the mission of human being's subject who exists in world. Advanced researches to analysis of in-jon tend to focus on rise of human status but this study do on universal subject not particular subject. This is to elaborate the point of issue. The point of view as rise of human status overlooks problem of relationship between human entities. who ingenerate hierarchy. In-jon is the universal subject of philosophical subject concepts which western philosophy have taken as main problem since Descartes. So we have to consider In-jon to be conceptual continuity concerning stream of history of ideas and communicate with ideas. A precedent study on 'injon' concept has weak conceptual analysis, which only emphasizes the greatness of mankind as compared with others. But that can't reveal In-jon based on the Daesoon thought. So I try to engraft the concept on development of subject ideas to get academic objectivity. In-jon is great in having universal subject to expand the authority of God to all creation. That is the last goal which subject can reaches through the development. Considering this regard the research direction of this study is very encouraging and significant. Western philosophy has important philosopher of the three, Descartes, Kant, Hegel. Those are a spectrum who show an aspect of subject ideas. The subject idea has become the middle of philosophical system since Descartes in modern. It is the right and necessary process to philosophy because human being has spirit or reason connected with God. So In-jon in Daesoon thought is academic concept comprising ontological and epistemological properties. So I try to analyse In-jon through that and have In-jon join the ranks of mainstream academics in this paper

The Hong Kong's Anti-Ordinance Amendment Movement is the most serious radical social movement since the 1997 return, which has served as the promotion of the 2014 Occupy Central Movement and broken through the violence baseline. The movement came from a criminal case committed in Taiwan,which gave a good reason and motivation for the HK government to amend the Fugitive Offenders Ordinance. The HK government has responded to the protests by strictly limiting the legal scope and transfer procedure, even giving up the legislative motion. But the protests still say no and develop into the constantly violent activities. Many of the protests have committed the crimes in HK laws,part of whom have been arrested,prosecuted and under judicially judged. It is necessary for the offenders to be punished to protect the authority of rule of law in HK. Two different paths for HK have fought against each other since the 1997 return: one is the "democratic-welfare" path taken by the Pan-Democratic Camp, the other is the "Legal-development" path taken by the Pan-Establishment Camp. The second path shares some nuclear characteristics of the so-called The China Model mainly shaped from the 40-years Reforms and Openness. However, the HK people can't understand the China Model very well and show great fear and distrust on the judicial system of Mainland China. The foreign powers such as US and UK have illegally interfered the HK issues which are deemed to be the domestic affairs of China. The so-called Sino-UK Joint Declaration can't serve as the legal basis for the interference. Taiwan, as a part of China, also plays a negative role in this movement for its electoral and political interest. Up to now, the movement has gone down and the HK government has the legal capacity to solve the problems under the supports from the central government and the HK people. The HK people love its rule of law and order under the constitutional framework of One Country Two System. After the movement,One Country Two Systems will be go on, and the integrated development under the policies of the central government will be the main stream. However, the relevant problems exposed by this movement muse be checked and solved legally and strictly,especially concerning the social inequality and youth development.

Multi shopping malls provide us new life-style nowadays with the term, malling. Multi shopping malls are consisted of selling space, entertainment space and convenience space so that arrangement and circulation planning of each facilities have large influence to users. Based on this influences, this study aims to provide basic data for multi shopping malls' circulation planning. Therefore, this study selected 6 multi shopping malls in Seoul and conducted survey that satisfaction of circulation planning of multi shopping malls. For user satisfaction investigation, we studied concept of multi shopping mall following Korean building act and selected composition and characteristics of circulation. Also, we classified the malls to size and circulation shapes for comparison of the satisfaction results. Classified types are high-rise and low-rise and they are separated to small size and big size. In addition, classified circulation shapes are categorized to net type, loop type, cyclical loop type and multi type by forms of central space and main stream of the malls.

South Korea experiences few large scale erosion and sedimentation problems, however, there are numerous local sedimentation problems. A reliable and consistent approach to modelling and management for sediment processes are desirable in the country. In this study, field measurements of sediment concentration from 34 alluvial river basins in South Korea were used with the Modified Einstein Procedure (MEP) to determine the total sediment load at the sampling locations. And then the Flow Duration-Sediment Rating Curve (FD-SRC) method was used to estimate the specific degradation for all gauging stations. The specific degradation of most rivers were found to be typically 50-300 tons/㎢·yr. A model tree data mining technique was applied to develop a model for the specific degradation based on various watershed characteristics of each watershed from GIS analysis. The meaningful parameters are: 1) elevation at the middle relative area of the hypsometric curve [m], 2) percentage of wetland and water [%], 3) percentage of urbanized area [%], and 4) Main stream length [km]. The Root Mean Square Error (RMSE) of existing models is in excess of 1,250 tons/㎢·yr and the RMSE of the proposed model with 6 additional validations decreased to 65 tons/㎢·yr. Erosion loss maps from the Revised Universal Soil Loss Equation (RUSLE), satellite images, and aerial photographs were used to delineate the geospatial features affecting erosion and sedimentation. The results of the geospatial analysis clearly shows that the high risk erosion area (hill slopes and construction sites at urbanized area) and sedimentation features (wetlands and agricultural reservoirs). The result of physiographical analysis also indicates that the watershed morphometric characteristic well explain the sediment transport. Sustainable management with the data mining methodologies and geospatial analysis could be helpful to solve various erosion and sedimentation problems under different conditions.

In this study, a dynamic numerical model, FLDWAV, is used for analyzing the backwater effect of flood stage in YeongWeol station, which is located on the confluence upstream where Pyeongchang river joins Han river. Given various inflow discharges of both main stream and tributary, the feasible stage-discharge relationships at the YeongWeol station and the upstream range of the backwater effect were computed. The results show that the relationships are completely different according to each of the inflow discharges from tributary and the maximum difference of stage is about 4.0 m. Therefore, the development of a single relationship of stage and discharge is very difficult problem in the zone of backwater effect. The increase of stage in the junction due to the lateral inflow has an effect on upstream stage up to about 8.0 km. The well-calibrated and verified dynamic wave routing model will be a useful tool for the flood forecast in the zone of backwater effect rather than conventional hydrological routing model.

A tracer test technique using a radioisotope was proposed to investigate pollutant mixing characteristics in rivers. The main advantages of radioisotope as a tracer in field tests are that it can be detected easily, and that its detection range is quite large. Also, using the radioisotope, the amount sorbed by the bed material and the biota may be a minimum. Field tracer tests were conducted at seven different sites in natural rivers with various meandering pattern. Based on the acquired data, the behavior of the tracer cloud in the intermediate-field was examined two-dimensionally, and dispersion coefficients were calculated using several evaluation methods. Results revealed that the tracer cloud was transported skewed to the outer bank and dispersion coefficients in bends were larger than those in straight reaches.
