With the rise of epigraphy and textology, and the emerge of many famous outstanding clerical script masters, Qing Dynasty becomes another important innovation period in the development of the clerical script. Jin Nong and Yi Bingshou are two important clerical script masters in the Qing Dynasty. Thus, researches on the courses of their careers as well as a comparative study between these two calligraphers, Jin Nong and Yi Bing, are specially important. The comparative study of Jinnong and Yibingshou's clerical script is a relatively new subject, which is entered from the angel of comparative perspective between their clerical scripts works. Through an in-depth research on different inheritance routes, which are origin from Han Dynasty clerical scripts, of Jin Nong and Yibingshou, it is found that these two calligraphers are different in innovation of clerical script style, theory of calligraphy and of clerical script practice. This paper focuses on a comparative study of the different clerical theories and clerical script works between Han Dynasty, Jinnong and Yi Bingshou. A comparative study of clerical script works of Jin Nong and Yibingshou in Qing Dynasty provides a more comprehensive and in-depth understanding on these two calligraphers; meanwhile, it provides valuable learning paths for later calligrapher in the field of clerical script, and can be regarded as references in the innovation of the official script style.

The web-based crowdfunding platform provides small-cap companies the opportunity to reduce financial risks and to reliably produce new products through pre-orders. Meanwhile, crowdfunding projects are also helping companies as a channel to test new products before mass production. Despite these advantages, from the point of view of businesses and consumers, it is true that web-based crowdfunding platforms have limitations in the retail environment. For example, the limited social elements of a web-based platform are somewhat in conflict with the basic characteristics of crowdfunding projects - which inevitably demand high social influences for the success. As such, understanding the mechanisms of social factors of crowdfunding platforms from the consumers' perspective is important. Therefore, in this study, we empirically tested the effect of social factors of crowdfunding platform on consumer participation and evaluation. Based on the Social Influence Theory and Social Presence Theory, we developed a conceptual framework where the social group size and social presence of other backers were the independent variables and the purchaser's intention to participate as the dependent variable. In the results, the size of the social group size and the perceived social presence have a significant positive effect on purchaser's participation intent. In addition, the social presence had a greater influence on the purchaser's intention to participate than the size of the sponsor's social group. We believe that our findings contribute to the extant literature by empirically demonstrating the valid effect of social factors of crowdfunding platforms on consumer evaluations.
The purpose of this study is to analyze the trends of Christian education research during the COVID-19 period. To this end, 172 theses published in the "Journal of Christian Education" and "Korea Society for Christian Education & Information Technology" pub-lished between March 2020 and June 2022 were analyzed according to the subfields and research methods of Christian education. As a result of the analysis, 38.5% of the total papers belonged to theories of Christian education. Papers related to practice of Christian education was 61.5%. Looking more closely at Christian education practice, papers related to classification by 'developmental stage' accounted for 25%, 'education field' accounted for 55.2%, 'function' accounted for 40.7% of the total papers. Regarding the classification of research methods, literature research accounted for 62.7% of the total studies, survey research methods accounted for 21.5%. Based on this, the main conclusions found in this study are as follows. First, the problems caused by the emergence and spread of the coronavirus began to be reflected in Christian education studies. Second, it was confirmed that the research method of Christian education, which had been biased toward liter-ature research, was recently converted from theory-centered to an attempt to balance theory and practice, and as convergence research increased, research topics and re-search methods were diversifying. Third, it was confirmed the need for category stand-ards that can analyze and classify studies in order to identify trends in Christian education research. Lastly, when considering all the papers, there are not many papers that fall under the classification by characteristics.
The method of Lagrange multipliers, one of the most fundamental algorithms for solving equality constrained optimization problems, has been widely used in basic mathematics for artificial intelligence (AI), linear algebra, optimization theory, and control theory. This method is an important tool that connects calculus and linear algebra. It is actively used in artificial intelligence algorithms including principal component analysis (PCA). Therefore, it is desired that instructors motivate students who first encounter this method in college calculus. In this paper, we provide an integrated perspective for instructors to teach the method of Lagrange multipliers effectively. First, we provide visualization materials and Python-based code, helping to understand the principle of this method. Second, we give a full explanation on the relation between Lagrange multiplier and eigenvalues of a matrix. Third, we give the proof of the first-order optimality condition, which is a fundamental of the method of Lagrange multipliers, and briefly introduce the generalized version of it in optimization. Finally, we give an example of PCA analysis on a real data. These materials can be utilized in class for teaching of the method of Lagrange multipliers.

The enhancement of the service life of damaged or cracked structures is a major issue for researchers and engineers. The hierarchic void element based on the integrals of Legendre polynomials is used to characterize the fracture behaviour of unpatched crack as well as repaired crack with bonded composite patches by computing the stress intensity factors and stress contours at the crack tip. Since the equivalent single layer approach is adopted in this study, the proposed element is necessary to represent a discontinuous crack part as a continuum body with zero stiffness. Thus the aspect ratio of this element to represent the crack should be extremely slender. The sensitivity of numerical solution with respect to energy release rate, displacement and stress has been tested to show the robustness of zero stiffness element as the aspect ratio is increased up to 2000. The stiffness derivative method and displacement extrapolation method have been applied to calculate the stress intensity factors of Mode I problem. It is noted that the proposed hierarchical void element can be one of alternatives to analyze the patched crack problems.

As part of the research on cultural factors that determine international tourism demand, this study was conducted based on regional interest and the need for understanding religion. The purpose of this study is to empirically test how religious factors affect tourism demand in Korea to find out that religious factors are important considerations in establishing tourism policies and strategies. To achieve the purpose of this study, the research target areas were selected as Thailand, Indonesia, and the Philippines, which have relatively many tourists visiting Korea among Southeast Asian countries and are well known for their religious characteristics. GDP and nominal exchange rate, which are economic factors, were selected as explanatory variables. And religious diversity was selected as a characteristic factor variable of the tourism demand model based on the characteristic theory. An empirical analysis was conducted through a gravity model. As a result of the estimation, it was found that GDP has a positive effect on tourism demand in Korea. Nominal exchange rate variables and religious diversity variables were found to have a negative effect on tourism demand in Korea. We have confirmed that religion is an important factor in choosing tourist destinations for Filipino, Thai, and Malaysian tourists visiting Korea, and they choose religiously similar destinations.

This study is a descriptive survey to develop a gamification e-learning class based on self-determination theory and to check its effectiveness. The data collection period was from March 1 to June 15, 2023, and 59 students at G University in G Metropolitan City were surveyed on class participation, learning immersion, and teaching presence before and after the course. IBM SPSS/Win 26.0 was used to analyze the collected data, and descriptive statistics, analysis of variance (ANOVA), and analysis of covariance (ANCOVA) were conducted. The results showed that the self-determination-based gamification class significantly improved students' class participation, learning engagement, and teaching presence (p<.05). An analysis of covariance (ANCOVA) was conducted to determine whether the general characteristics of the participants affected the results of the post-test, and gender affected the post-test results of learning engagement, with an effect of 7.9%. Based on the results of this study, it can be seen that self-determination-based gamification e-learning class is effective in improving learners' class participation, learning engagement, and teaching presence. As the demand for e-learning in universities is expanding, self-determination-based gamification e-learning classes should be developed in various fields of liberal arts and majors.

In this paper, we propose an image downscaler used in multimedia video applications, such as DTV, TV-PIP, PC-video, camcorder, videophone and so on. The proposed image downscaler provides a scaled image of high-quality and high-performance. This paper will explain the scaling theory using two-dimensional digital filters. It is the method that removes an aliasing noise and decreases the hardware complexity, compared with Pixel-drop and Upsamling. Also, this paper will prove it improves scaling precisians and decreases the loss of data, compared with the Scaler32, the Bt829 of Brooktree, and the SAA7114H of Philips. The proposed downscaler consists of the following four blocks: line memory, vertical scaler, horizontal scaler, and FIFO memory. In order to reduce the hardware complexity, the using digital filters are implemented by the multiplexer-adder type scheme and their all the coefficients can be simply implemented by using shifters and adders. It also decreases the loss of high frequency data because it provides the wider BW of 6MHz as adding the compensation filter. The proposed downscaler is modeled by using the Verilog-HDL and the model is verified by using the Cadence simulator. After the verification is done, the model is synthesized into gates by using the Synopsys. The synthesized downscaler is Placed and routed by the Mentor with the IDEC-C632 0.65${\mu}{\textrm}{m}$ library for further IC implementation. The IC master is fixed in size by 4,500${\mu}{\textrm}{m}$$\times$4,500${\mu}{\textrm}{m}$. The active layout size of the proposed downscaler is 2,528${\mu}{\textrm}{m}$$\times$3,237${\mu}{\textrm}{m}$.
The purpose of this study was to investigate the existing theories related to overtraining syndrome and to examine the mechanism of overtraining syndrome from the viewpoint of brain science by examining domestic and foreign literature related to the relationship between overtraining syndrome and brain neurotransmitter. The aim of this paper is to provide basic data that can improve the understanding of the mechanism of overtraining syndrome and the role of neurotransmitters and neuromodulators. The results of this study and a number of hypotheses about the overtraining syndrome were proposed, each with strengths and weaknesses. Similar symptoms that occur when the concentration of serotonin in the neurotransmitter increases are related to signs and symptoms of overtraining syndrome. However, it has not been validated to date because it can not distinguish the mechanism of the mediator between the central nervous system and the peripheral nerves. This study suggests that the mechanism of overtraining syndrome will provide important basic information to understand the complex causes of overtraining syndrome through the interaction of existing theory and brain neurotransmitter. Although there has been a lack of studies on the mechanism of overtraining syndrome and brain neurotransmitters so far, we hope that this study will provide an opportunity for more and more people to broaden their understanding of overtraining syndromes.

This Research is based on the theory of the prior researches that have demonstrated a positive impact of the entrepreneurship and competitive advantages on business performance. And the purpose of this research which approaches in the viewpoint of combining a entrepreneurial attribute including two factors(entrepreneurship and commercialization capabilities) and the differentiated competitive advantage as a role of core competence is to examine how the combined competence affects the business performance. In order to achieve this purpose, we conduct a survey for CEO of 250 small firms which belong to the start-up phase and are located in the 6 administrative region with the assistance of Small & Medium Business Administration representatives and analyze empirically the survey data by utilizing statistical program(Spss 18.0). As the results, we conclude that the entrepreneurial attributes of small firms' CEO and DFCA have a positive impact on business performance respectively and the entrepreneurship, one of the two entrepreneurial factors, has a positive impact on choosing DFCA. Also we report that DFCA plays a mediating role with regards to relationship between entrepreneurial attributes and business performance. Therefore, this research suggests the followings: First, the CEO of start-up business should focus on building a differential competitive advantage which is the basis for creating competitiveness from the initial point. Secondly, he should make a alignment for core competencies, in order to reach the stable growth phase in the shortest period, through which the entrepreneurial attributes is to be inherent as a discriminatory competitive competence. Third, he should promote to establish a business strategy based on strengthening of entrepreneurship and discriminatory competitive as a growth strategy during start-up phase.
