Memorials in Joseon Dynasty created a arena where the intellectual and political power met. This thesis traces the process of a certain political faction's rebuilding of the political structure of the elite groups by leading the intellectual controversies through memorials, especially those about the evaluations of Pak Setang(朴世堂) and I Gyeongseok(李景奭). This is what happened: Song Siyeol(宋時烈) submitted a memorial which disputed I Gyeongseok's petition, which provoked complete controversies around the memorials between Noron(老論) and Soron(少論). This led to the academic censorship against Sabyeonrok written by Pak Setang. The analysis of act of writing and submission of memorials by Noron and the role of the Kim Family of An-dong(安東 金門) specifically is the main topic here. The members of Soron ceaselessly criticized Song Siyeol, while the Kim Family strongly defended him. The trigger of the strife was a letter written by Kim Chang-Heup(金昌翕), a member of the Kim Family and the Kims played a significant role in the background during the process of political fights using memorials. The series of memorials criticized or supported certain political figure or his writings, but the opinions of Noron and Soron were directly opposite to each other. Even though the expressed difference was the result of the existing political factions, however, it also caused the new power structure of elite groups. The expressions and logics used in the arguments also have its significance. The Noron's memorials evaluated the contemporary people and their writings based on Chu-Hsi and Song Siyeol, who was regarded as a identical figure of Chu-Hsi. The arguments and writing strategies in this regard gained political strength enough to reorganize the intellectual society by changing alignment of political parties, and this led to the rebuilding of academic environment afterward.

The purpose of this study was to investigate orientation toward teaching of science teachers had shown in lesson on Law of Definite Composition for middle school students and the factors which influenced its formation. To achieve this, we collected survey materials by recording and analyzing lessons of 8 teachers, interviewing them, and using CoRe questionnaire. From teachers' activities in lessons, we found their orientation toward science teaching, and through analyzing collected materials, drew the factors which influenced the formation of orientation toward science teaching. The result identified two types of orientation toward science teaching: activity-directional and lecture-directional. The former, activity-directional was categorized further as exploration and non-exploration; the latter as interaction-centered and content delivery. The main factors which affected the formation of orientation toward science teaching were reflective thinking through teaching experiences, interaction with colleagues, consideration on education environment, training as a learner, and their own interest and curiosity. Among them, the reflective thinking through teaching experiences was strongest cause, and teacher's interest and curiosity was even limited, also influenced positively. On the other hand, unlikely other factors, consideration on education setting affected negatively to build teacher's teaching orientation. Interaction with colleagues, training for teachers by universities and graduated schools acted on a bit, but had a limit just for mainly developing science content knowledge.

The power production using renewable energy is more important because of a limited amount of fossil fuel and the problem of global warming. A concentrative photovoltaic system comes into the spotlight with high energy production, since the rate of power production using solar energy is proliferated. These systems, however, need to sophisticated tracking methods to give the high power production. In this paper, we propose a hierarchical tracking system using modular Bayesian networks and a naive Bayes classifier. The Bayesian networks can respond flexibly in uncertain situations and can be designed by domain knowledge even when the data are not enough. Bayesian network modules infer the weather states which are classified into nine classes. Then, naive Bayes classifier selects the most effective method considering inferred weather states and the system makes a decision using the rules. We collected real weather data for the experiments and the average accuracy of the proposed method is 93.9%. In addition, comparing the photovoltaic efficiency with the pinhole camera system results in improved performance of about 16.58%.

This study is to set up a hypothesis and a research model based on how much the relational benefits can affect customer satisfaction and long-term relationship with the theoretical and practical results of established precedent researches, to analyze the structural equation model on casual dining restaurant diners, to evaluate the research model and subsequently to provide marketing implications. First of all, social and psychological factors prove to be influential among relational benefits felt by diners-out. Secondly, customer satisfaction has influence on long-term commitment for a restaurant. In other words, the higher customer satisfaction level for a restaurant is, the stronger willingness a customer has to recommend or revisit the restaurant, as several precedent studies support. As demonstrated in indirect advantages, these social and psychological benefits felt by diners-out have mighty effects on long-term relationship orientation, and satisfaction levels prove to be an important medium which can make these influences. As a result, restaurant employees' attitude toward customers is the most important factor rather than economic benefits such as reduced price, free gifts and coupons are, since customers put social and psychological benefits forward like intimate terms with restaurant workers, a sense of stability, and a relief from uneasiness. Therefore, constant service education should be done from the start to cope with customers' demands fast and flexibly and increase customer satisfaction.

Coronavirus disease 19 (COVID-19) is caused by SARS-CoV-2 (Severe Acute Respiratory SyndromeCoronavirus 2). To date, seven coronaviruses that can infect humans were reported. Among them, infections with four coronavirus strains (HCoV-229E, HCoV-OC43, HCoV-NL63, and HCoV-HKU1) resulted in mild symptoms such as common cold, whereas SARS-CoV and MERS-CoV caused severe symptoms and epidemics in 2002 and 2012, respectively. In the most recent, SARS-CoV-2 was first reported in Wuhan, China in December 2019 and became a notorious cause of the ongoing global pandemics. To diagnose, treat, and prevent COVID-19, the development of rapid and accurate diagnostic tools, specific therapeutic drugs, and safe vaccines essentially are required. In order to develop these powerful tools, it is prerequisite to understand a phenotype, a genotype, and life cycle of SARS-CoV-2. Diagnostic techniques have been developing rapidly around world and many countries take the fast track system to accelerate approval. Approved diagnostic devices are rapidly growing facing to urgent demand to identify carriers. Currently developed commercial diagnostic devices are divided into mainly two categories: molecular assay and serological & immunological assay. Molecular assays begins the reverse transcription step following polymerase chain reaction or isothermal amplification. Immunological assay targets SARS-CoV-2 antigen or anti-SARS-CoV-2 antibody of samples. In this review, we summarize the phenotype, genome structure and gene expression of SARS-CoV-2 and provide the knowledge on various diagnostic techniques for SARS-CoV-2.

With the recent development of advanced GIS and complex spatial analysis technologies, the more sophisticated technologies are being required to support the advanced knowledge for solving geographical or spatial problems in various decision support systems. In addition, necessity for research on scientific crime investigation and forensic science is increasing particularly at law enforcement agencies and investigation institutions for efficient investigation and the prevention of crimes. There are active researches on geographic profiling to predict the base location such as criminals' residence by analyzing the spatial patterns of serial crimes. However, as previous researches on geographic profiling use simply statistical methods for spatial pattern analysis and do not apply a variety of spatial and temporal analysis technologies on serial crimes, they have the low prediction accuracy. Therefore, this paper identifies the typology the spatio-temporal patterns of serial crimes according to spatial distribution of crime sites and temporal distribution on occurrence of crimes and proposes STA-BLP(Spatio-Temporal Analysis based Base Location Prediction) algorithm which predicts the base location of serial crimes more accurately based on the patterns. STA-BLP improves the prediction accuracy by considering of the anisotropic pattern of serial crimes committed by criminals who prefer specific directions on a crime trip and the learning effect of criminals through repeated movement along the same route. In addition, it can predict base location more accurately in the serial crimes from multiple bases with the local prediction for some crime sites included in a cluster and the global prediction for all crime sites. Through a variety of experiments, we proved the superiority of the STA-BLP by comparing it with previous algorithms in terms of prediction accuracy.

ICT sector has been made a great deal of achievements for past 20 or more years in the aspects of the industrial promotion and the efficiency improvement under the strong leadership by the government for the informatization and still leads the Korean industries. However, the previous studies are mostly on how the quantitative growth of patents impacts a company's management achievements while being insufficient on the qualitative level. In this study, an analysis is attempted on the impact from the qualitative level of patents held by a ICT company leading Korean industry to its management achievements. In other words, if the concentration of technological innovation activities, a scale to measure the qualitative level of possessed patents is influential to the growth and the profit of a company is analyzed. The analysis result shows that the current time technological superiority index, RTA and the concentration index, CRn of the technological innovation activities significantly impact to the growth and the profit of company. This study demonstrates the positive impact from a highly qualitative level of patents to the growth and the profit of a company in ICT sector in the current circumstance of insufficient researches on the qualitative level of patents. Therefore, this study is expected to present a new start point for the future studies.
