This paper is a study on the Jeonwonsasiga of Shin Gye Young. Jeonwonsasiga is as a out of Sasiga-Line(사시가계) Yeonsijo(연시조), the singing Spring. Summer. Autumn, Winter and Jesuk. The meanwhile, a study on the Jeonwonsasiga is in the relations with other literary works, or a history of Siga in 17th century. A out of specific character's of Jeonwonsasiga is the singing Spring, Summer, Autumn, Winter and Jesuk about order. Jesuk with a New year's Eve, is the stand for a watch night.'Chun Ha Chu Dong(Spring, Summer, Autumn, Winter, 춘하추동)' are included in the Sasi of One Year(일년 사시), And the Jesuk is included in the Sasi of one day(하루 사시). Buy the way, Jeonwonsasiga make an equal about all of two. And then, this paper is focused on the 'Jesuk'. The role of Jesuk is coexistence together with the Sasi of One Year and the Sasi of one day. That is to say, Jeonwonsasiga's singing from the 1st works to the 8st works are the Sasi of One Year in the surface. But, singing the Sasi of One Day of 'Dan Ju Mo Ya(단주모야)' in the inside story. And Jesuk is a finished role the mean's of literary works. And this provide an opportunity which can be speaker's recognition of Jeonwon (전원). The Jeonwonsasiga of ten works are have a value of Yeonsijo in continyal structure. And so. it is to be watched sense of proportion of Yeonsijo in the 17th century.

The purpose of this study is to analyze the first edition of Brown's Subject Classification and to understand the implications of today's library classification. For this purpose, the first edition of the Subject Classification published in 1906 was analyzed. The analysis results are divided into three main areas. First, SC is divided into eleven main classes and each class is subdivided into enumerated subdivisions from 000 to 999. Second, As a method of synthesizing the classification numbers, there were three methods of synthesis. There was a flexibility to insert a new classification number at the appropriate location when a new topic that does not appear in the main table appeared. Implications for classification studies can be divided into four main categories. First, SC proposed a method of classification number synthesis for composite topics, which is an innovative method that was not available in previous library classification. Second, the subject matter was explained in various aspects through the operation of auxiliary tables supporting the facets. Third, it is possible to easily insert a new topic into the classification system by using the SC that can have a flexible classification system for each library, or to use a short classification number according to the size of the library collection. Fourth, it provided a directory that can be considered as access points for digital materials.

Thirty-five of Hwaban of Jeongjagak had been built in the last three hundred years, which means a Hwaban was made in almost every ten years. Jeongjagak is a building that requires a certain ornamentation having the identical Gongpo type, called E-ikgong, and maintains the same shape for a long time. While Hwaban is an element that faithfully serves the ornamental role, the field study found that Hwaban-chogak went through various changes over the years unlikely to Jeongjagak. This study enumerates and classifies the various types of Hwaban-chgak by outlining the similarities/differences of the various types of Hwavanchogak, and by discovering what the craftsmen aimed to express through the Hwaban-chogaks. As a result, Hwaban-chogak can be generally divided into two categories depending on the starting point of Chogak: 'Downward-Type' and 'Upward-type' and the study tried to find the origin of that. The first represents the stems of Hwaban crafts flowing from top to bottom, and the latter showing the opposite direction. Around 1740s Upward-type can be chronologically caragorised as; 'original- type' which contains lotus and 'modified- type' which eliminates lotus. It is inferred that the modified-type was caused by the employment system of the craftsmen. It is also recognized that the main frame of Hwaban-chogak had been maintained despite the fact that Chogak became increasingly ornamental for the next a hundred years from the Hwaban-chogak drawings in Whaseong-seongyeog-uigwe, which was completed in 1796. The study has a limitation that the focus of the research is only on the Hwaban of Jeongjagak and expected to look into Hwaban in the context of other construction elements such as Ikgong, Daegong and Anchogong for further studies.

Collaborative Cyber-Physical Systems (CCPS) are those systems that contain tightly coupled physical and cyber components, massively interconnected subsystems, and collaborate to achieve a common goal. The safety of a single Cyber-Physical System (CPS) can be achieved by following the safety standards such as ISO 26262 and IEC 61508 or by applying hazard analysis techniques. However, due to the complex, highly interconnected, heterogeneous, and collaborative nature of CCPS, a fault in one CPS's components can trigger many other faults in other collaborating CPSs. Therefore, a safety assurance technique based on fault criticality analysis would require to ensure safety in CCPS. This paper presents a Fault Criticality Matrix (FCM) implemented in our tool called CPSTracer, which contains several data such as identified fault, fault criticality, safety guard, etc. The proposed FCM is based on composite hazard analysis and content-based relationships among the hazard analysis artifacts, and ensures that the safety guard controls the identified faults at design time; thus, we can effectively manage and control the fault at the design phase to ensure the safe development of CPSs. To justify our approach, we introduce a case study on the Platooning system (a collaborative CPS). We perform the criticality analysis of the Platooning system using FCM in our developed tool. After the detailed fault criticality analysis, we investigate the results to check the appropriateness and effectiveness with two research questions. Also, by performing simulation for the Platooning, we showed that the rate of collision of the Platooning system without using FCM was quite high as compared to the rate of collisions of the system after analyzing the fault criticality using FCM.

This Articles intend to articulate The Tao(道) and Te(德) in Confucian analects("論語") Tao & Te is key concepts in Confucian analects. Tao is the Way of human life. Te is the incarnation of the Way. Jen(仁) is the universal Virtue of Human beings. Therefore, Confucius said, "If Human beingsa bo the Virtue proper to Humanity, what has to do with the Rites of propriety and Music?". Confucian's Human relationship is altruism(恕). Chu-Hsi and Dasan uphold and reestablished Tao & Te and Jen as maim concept of Confucius Analects. Jen is a practical methodology of Tao and Te. Confucius said, 'Let the will be seat on the path of duty.' 'Let every attainment in what is good be firmly grasped.' 'Let perfect Virtue be accord with. Tao(道), Te(德) and Jen(仁) is Trinity in Confucian Analects. Dasan redefined Tao and Te as his Commentary of Confucian analects("論語古今註"). Dasan interpreted that Te is achieved only by Human beings's behavior. But Chu-Hsi' Te is substance of Mind(心之體). He interpreted Te as an innate idea.

A plant factory is a facility that creates an artificial environment in a controlled space and produces plants systematically through automated facilities. However, automation in the cultivation process is insufficient compared to the internal environment control technology in plant factories. This causes the problem of an increase in operating costs due to the input of a large number of workers. Therefore, this study aims to evaluate economic feasibility by comparing before and after introducing automation in the cultivation process of plant factories. The target plant factory to be analyzed was selected, and the break-even point analysis method was used by comparing the cost required compared to the operating period. As a result, the break-even point was analyzed to be 3.4 years when automation was introduced into six processes for plant cultivation. Therefore, it can be judged that the introduction of automation is excellent in terms of economic feasibility when the target plant factory has been operated for more than 3.4 years. This study is expected to be used as basic data to analyze the economic feasibility of introducing automation in domestic and foreign plant factories.

Major egg white proteins and their hydrolysates serve as functional food ingredients that have certain metal-chelating properties. Employing egg white proteins and their hydrolysates to scavenge dietary oxalates is anticipated to have beneficial effect in the prevention of kidney stones. The objective of this study was to determine the biogenic oxalate-chelating activity of ovalbumin, ovomucin, and ovotransferrin and their hydrolysates. To prepare oxalate extracts, 30 mL of 0.25 N HCl was added to separately to 0.5 g of dried spinach and starfruit powders followed by boiling for 15 min, and after cooling, the addition of a further 20 mL of 0.25 N HCl. Having prepared these extracts, ovalbumin, ovomucin, and ovotransferrin and their hydrolysates were separately mixed with oxalate extracts and incubated at 3℃ for 24 h. Following centrifugation, supernatants were analyzed by HPLC using a reverse-phase C18 column coupled with a diode array detector. We found that all assessed proteins and their hydrolysates showed biogenic oxalate-chelating activity against the oxalates of spinach. In contrast, however, only ovalbumin, ovalbumin-hydrolysate, and ovomucin showed chelating activity (57.10%±8.84%, 85.44%±5.30%, 73.20%±4.13%, respectively) against the oxalates of starfruit (P<0.05). Overall, hydrolyzed ovalbumin was identified as the most effective chelator of the oxalates both spinach and starfruit. In this study, we thus established that the assessed egg white proteins and their hydrolysates have oxalate-chelating activity in vitro, thereby indicating that these compounds have potential utility as nutraceuticals for the chelation of dietary oxalate. However, further research will be necessary to verify their oxalate-chelating activities against different fruits and vegetables and under specific in vivo conditions and against purified oxalate.

Unlike previous studies, this study looked at the effect of the ideological tendencies of local government heads on the social welfare budget as a longitudinal study. This study was made possible by the election of the head of a progressive group in Gumi-si, a stronghold of conservatives, after the implementation of the local self-government system. Therefore, in this study, the change process of the political ideological orientation of Gumi-si's heads and the social welfare budget by year were listed and time-series analysis was conducted using actual cases of Gumi-si, Gyeongbuk for more than 12 years. As a result of the analysis, first, as in the cross-sectional analysis, in the longitudinal study, the change in the rate of increase in the social welfare budget according to the political ideological tendencies of the head of the local government showed a meaningful difference. Second, as in the previous cross-sectional analysis, the social welfare budget increased in the year before the election. Third, the same change in the growth rate as in the second did not appear at the end of the third elected term. All studies on the relationship between the political ideological tendencies of local government heads (including local councils) and the social welfare budget have been cross-sectional. However, this study has great implications in terms of the results of the first longitudinal cross-sectional analysis.

The purpose of this study is to look qualitatively into how efficiently and reasonably a computer can learn themes related to the Nature of Science (NOS). In this regard, a corpus has been constructed focusing on literature (920 abstracts) related to NOS, and factors of the optimized Word2Vec (CBOW, Skip-gram) were confirmed. According to the four dimensions (Inquiry, Thinking, Knowledge and STS) of NOS, the comparative evaluation on the word-level word embedding was conducted. As a result of the study, according to the previous studies and the pre-evaluation on performance, the CBOW model was determined to be 200 for the dimension, five for the number of threads, ten for the minimum frequency, 100 for the number of repetition and one for the context range. And the Skip-gram model was determined to be 200 for the number of dimension, five for the number of threads, ten for the minimum frequency, 200 for the number of repetition and three for the context range. The Skip-gram had better performance in the dimension of Inquiry in terms of types of words with high similarity by model, which was checked by applying it to the four dimensions of NOS. In the dimensions of Thinking and Knowledge, there was no difference in the embedding performance of both models, but in case of words with high similarity for each model, they are sharing the name of a reciprocal domain so it seems that it is required to apply other models additionally in order to learn properly. It was evaluated that the dimension of STS also had the embedding performance that was not sufficient to look into comprehensive STS elements, while listing words related to solution of problems excessively. It is expected that overall implications on models available for science education and utilization of artificial intelligence could be given by making a computer learn themes related to NOS through this study.
