The purpose of this study is to prove the existence of the meridians by analyzing the effect of bloodletting cupping on Back-Shu Points and venesection on sabonghyeul, which are treatments for gastrointestinal and circulatory diseases with Ryodoraku. We selected the charts of 30 patients who received the treatment such as bloodletting cupping on Back-Shu Points and venesection on sabonghyeul for gastrointestinal and circulatory diseases. First, the Ryodoraku test was conducted in a stable state. After taking a rest on the bed, he performed a venesection on sabonghyeul. And bloodletting cupping on Back-Shu Points was performed with prone position. After all the procedures were completed, Ryodoraku test was performed again. And the result was compared with previous test status. By bloodletting cupping on Back-Shu Points and venesection on sabonghyeul, the deviation between the current value of the right F5 (gallbladder)· H4 (small intestine)· H6 (large intestine) (p<.05, p<.05, p<.001), left H5 (triple energizer) (p<.05) and the average current of 24 source points was significantly decreased. The difference between the left and right currents at the site of F3 (kidney) showed a significant increase (p<.005). It can be proved the existence of meridians that Bloodletting cupping on Back-Shu Points and venesection on sabonghyeul showed significant changes in the F5 (gallbladder), H4 (small intestine), H6 (large intestine), F3 (kidney), H5 (triple energizer) in digestive and circulatory symptoms by Ryodoraku test.

This study examines the status quo of the support system for companies of persons with disabilities in Korea, and then estimates the corporate income tax reduced from a special taxation system, same as one applied to social enterprises and standard workplace for persons with disabilities, using 「Data for registered companies of persons with disabilities」(2020.6) by the Disable Enterprise Business Center. Now companies of persons with disabilities have more than 87% in the business continuity rate, and their employment rate of the average rate for 2015-2017 is higher than public institutions and private companies, which is in line with the government's employment promotion policy for the disabled. However, article 14 (Support in Taxation) of the 「Act On The Facilitation Of Entrepreneurial Activities Of Persons With Disabilities」 is still declarative and optional. Meanwhile, the corporate income tax reduced by a simulation method was calculated to be about KRW 130.1 billion for 5 years (KRW 26.02 billion per year). In this context, when comparing the tax revenue to be reduced with a positive effect by securing the effectiveness of Article 14, it can be said that the tax support for companies of persons with disabilities is feasible.

Recently, interleukin 34 (IL-34) was identified as the second functional ligand for macrophage colony-stimulating factor receptor (M-CSFR). IL-34 functions similarly to M-CSF through its binding to the M-CSFR. There is still insufficient information on IL-34 in chickens, which has until now been reported only through predicted sequences and not through experimental research. Thus, to confirm its expression and to determine its potent biological activity, several chicken lines and cell lines were used. Cloning of recombinant chicken IL-34 and M-CSF genes was performed to investigate their modulatory effects on proinflammatory cytokine expression in vitro. The expression levels of IL-34, M-CSF, and M-CSFR genes were upregulated in broiler chickens with leg dysfunction (cause unknown). However, IL-34 was downregulated in most pathogen-stimulated tissues. M-CSFR expression was enhanced by recombinant IL-34 and M-CSF proteins in vitro. IFN-γ expression was enhanced by recombinant IL-34, but not by M-CSF. However, IL-12 expression was not regulated in any of the treated cells, and IL-1β was decreased in all tissues. These results indicate that IL-34 and M-CSF have roles in both the classical and alternative macrophage activation pathways. Collectively, our findings demonstrate the expression of IL-34 in chickens for pathogenic trials, both in vitro and in vivo. Our results suggest that the IL-34 protein plays a role in both pro- and anti-inflammatory functions in macrophages. Therefore, further research is needed to determine the cytokines or chemokines that can be induced by IL-34 and to further elucidate the functions of IL-34 in the inflammatory pathway.

The digital phase-locked loops(DPLL) is a circuit used for phase synchronization and has been generally used in various fields such as communication and circuit fields. State estimators are used to design digital phase-locked loops, and infinite impulse response state estimators such as the well-known Kalman filter have been used. In general, the performance of the infinite impulse response state estimator-based digital phase-locked loop is excellent, but a sudden performance degradation may occur in unexpected situations such as inaccuracy of initial value, model error, and disturbance. In this paper, we propose a minimum variance finite impulse response filter with optimal horizon for designing a new digital phase-locked loop. A numerical method is introduced to obtain the measured value interval length, which is an important parameter of the proposed finite impulse response filter, and to obtain a gain, the covariance matrix of the error is set as a cost function, and a linear matrix inequality is used to minimize it. In order to verify the superiority and robustness of the proposed digital phase-locked loop, a simulation was performed for comparison and analysis with the existing method in a situation where noise information was inaccurate.

The purposes of this study are to develop the standardized tests of career preparation behavior of career preparation behavior for college students. For these, the 'Career Preparation Behavior Scale for College Students' which was developed in 2011 was reviewed and revised. After 609 students were involved and analyzed for the pretest, 1,244 subjects were collected by taking into account gender, grade, major, and location of colleges for developing a standardized test. The Career Preparation Behavior Scale consisted of 3 subareas and 30 items: 11 items for learning area, 12 items for counseling and information collecting area, 7 items for employment action area. The levels of reliabilities, construct validity, discriminant validity, and the concurrent validity were relatively high. Also, the suitability index of the structural model was analyzed to check the structural significance. The degree of career reparation behavior among norm groups was increased in general according to the grades. Scores of students majoring in humanities and social sciences received significantly high scores compared with those of majoring in science and technology or in art and music. But the levels of satisfaction on career preparation behavior were no difference according to gender, grade, and major. 'The Standardized Career Preparation Behavior Scale for College Students' would be used for conducting career education or programs for college students in the future.

Recently, there is a great expectation for the sustainable effect of TOD and apply it to urban planning and design. However, there are few research on the quantitative evaluation method of the effect. The purpose of this study is to propose a quantitative way to assess the effectiveness of TOD(Transit Oriented Development)'s vehicle traffic reduction in the urban planning phase, based on the land-use plan. Firstly, it proposes a method to convert the information contained in the land-use plan into a network and secondly a method to estimate the travel distance based on the network. In the first phase, the roads in the land-use plan are converted into links and the intersection of the roads into nodes. The area and the height of the zones included in the land-use plan are converted into the weights on adjacent nodes. The second phase assumes the frequency at which travel occurs between nodes on the network is relative to the weights and estimates the travel distance by dividing it into a pedestrian and a vehicle. Then, taking the city without TOD as the object, through comparison present city and alternatively redesigned city to the analysis of TOD effect. In this study, the application of these methods to Bundang as of 1997 and alternatively redesigned Bundang showed that about 39.94 percent of the vehicle traffic reduction effects occurred. Furthermore, the pedestrian traffic ratio of alternatively redesigned Bundang increased to 2.39%.

Chinese xian-xia films is a new genre that occurred through the fusion of the genre of martial arts and fantasy. This study analyzed the development of xian-xia films and the space aesthetics of xian-xia films through the miseenscene of the journey to the west films. In particular, the space for xian-xia in the films is divided into the human, urinary, heaven world and the space of conflict. It looks like the fantastic Middle Earth that Tolkien presented, however it is discriminatory in that it shows a highly Chinese appearance and overlapping world centered on the natural environment (the world of Mountains and Livers), such as mountains, deserts, caves, and grasslands, which usually appears in traditional martial arts history. Resently, the boom of journey to the west films is regarded as the change of the Chinese film industry under the influence of the development of IP (Intellectual Property) industry and the western fantasy genre in the 21st century China. This change marks the birth of the new Chinese fantasy "xian-xia" genre with the spirit of the present era that transcends the original world of journey to the west through the hybridization of the genre.

This paper examines the background and content of Thomas Jefferson's botanical garden plan for the University of Virginia. When Jefferson promoted the establishment of a botanical garden, European botanical gardens were evolving from physic gardens, and American botanical gardens were in their infancy. Accordingly, this paper compares the Botanical Garden Plan for the University of Virginia with contemporary botanical gardens. This is examined by outlining the trends of botanical gardens in Europe and the United States around the nineteenth century, analyzing their function and spatial structure. Also, Jefferson's perspective on botany, his plan, and botanical gardens are reviewed. This study found that Jefferson's project had its background in the social recognition of the importance of botany as a practical science, advancing the national economy, which was a prominent goal in late eighteenth-century Europe, and in developing networks of exchanging plants and information concerning botany and botanical gardens. Based on the botanist Correia's opinion on the role of a public botanical garden, the Botanical Garden Plan for the University of Virginia was developed by Jefferson as an action plan, including its site creation, space organization, and supplying of plants. Compared to the other contemporary botanical gardens, the University of Virginia's Botanical Garden Plan has the following characteristics. First, like European gardens in the late eighteenth century, it evolved from being a physic garden to a botanical one. As such, it emphasized botanical research and education over medicine, creating a tree garden and a plant garden. Second, it differed from many European and American botanical gardens in that it rejected decorative elements, refused to install a greenhouse, and attempted to spread practical overseas plants suitable to the local climate. This study contributes to broadening the history of botanical gardens at the turn of the nineteenth century.

This study aims to explore the influencing factors and the process of enhancing science self-efficacy (SSE) and to lay the foundation in understanding science self-efficacy of students. The ten categories related to the science self-efficacy were derived through the coding of the interview data based on the grounded theory and paradigm analysis to develop a process model of science self-efficacy improvement. Through the process analysis, four cyclical phases were found in the process of enhancing SSE: 'Entering into learning science' phase, 'enhancing SSE' phase, 'adjustment' phase, and 'result' phase. More specifically, the phase of 'entering into learning science' is where students choose science track and stimulated to construct SSE. The phase of 'enhancing SSE' is where students taking a science track actively learn science and perform science activities. In the phase of 'adjustment', students come to have successful performance about learning science and performing science activities by using diverse strategies. Finally, 'result' phase indicates different appearances of students depending on SSE levels. The phases were non-linear and periodically repeat depending on situation. The core category in the selective coding was indicated to be 'enhancing science self-efficacy.' Students' SSE form by learning science and performing science activities. These finding may help better understand the behavior of students who are taking a science track by facilitating effective science learning through the increase of their SSE levels.

The aim of this study was to investigate the short term effects of early intervention on alcohol knowledge, alcohol expectancies, drinking refusal self-efficacy for alcoholism prevention in adults and to examine its applicability in the field. This study was a non-equivalent control group pre-post quasi-experimental design. The participants were currently working, and were 12-25 points on result of the Alcohol Use Disorders Identification Test(AUDIT). The participants were a total of 25 men: 13 in the intervention group and 12 in the control group. The intervention group participated in early intervention program once a week for 4 weeks and the control group received only a booklet of alcohol related information. A chi-square test, t-test, Mann-Whitney U test were analyzed by using IBM SPSS Statistics 20.0. The intervention group had significantly higher the alcohol knowledge(t=1.258, p= .002), the negative alcohol expectancies(t=-1.346, p= .042), and the drinking refusal self-efficacy(t=2.817, p= .010) than the control group. In the future, it is need to apply the criteria of problem drinkers considering cultural characteristics, recruitment of participants, and motivational enhancement intervention using motivational interviewing. Especially, web-based alcohol related information providing program will help raise awareness of problem drinking. Early intervention program needs to be applied in community settings where problem drinkers are easily accessible.
