With the decline in the college student population and the increase in the youth unemployment rate, the university began to be interested in starting a business. Under the initiative of the government, the start-up support project was reflected in the university's educational programs, which led to the university students receiving various start-up support benefits. In response to the expansion of entrepreneurship education, various entrepreneurship education programs and support programs were applied in line with the government's efforts to start college students. As a result, students' entrepreneurial competence and willingness to start up increased. College student entrepreneurs and entrepreneurs are increasing. The increase of university student start-up companies is taking place in the entrepreneurial education environment within the university, and the support of university, community, and start-up support institutions for university student start-up, the starting point of the start-up ecosystem, is paying off. It can be seen that the youth entrepreneurship ecosystem based on university entrepreneurship education is in place. The university supports the entire business process from idea development, such as start-up classes, start-up club support, patent application support, prototype development support, and investment linkage. However, there is a university that develops and operates a unique program for each school and a university that does not. Therefore, it is necessary to develop an education program that can produce efficient results. The purpose of this study is to support the start-up program of the university to be the consumer-centered start-up support.

In this study, nano-scaled shielding materials were assembled and fabricated by doping different weight percentages of Nano-mercuric oxide (N-HgO) into Nano-Bentonite (N-Bent) based on using (100-x% N-Bent + x% N-HgO, x = 10, 20, 30, and 40 wt %). The fabricated N-HgO/N-Bent nanocomposites were characterized by FT-IR, XRD, and SEM and evaluated to evaluate their shielding properties toward gamma radiation by using four different γ-ray energies form three point sources; 356 keV from 133Ba, 662 keV from 137Cs as well as 1173, and 1332 keV from 60Co. The γ-rays mass attenuation coefficients were plotted as a function of the doped N-HgO concentrations into N-HgO/N-Bent nanocomposites. The computed values of mass attenuation coefficients (µm), effective atomic number (Zeff) and electron density (Nel) by the as-prepared samples were found to increase, while the half value layer (HVL) and mean free path (MFP) were identified to decrease upon increasing the N-HgO contents. It was concluded also that the increase in N-HgO concentration led to a direct increase in the mass attenuation coefficient from 0.10 to 0.17 cm2/g at 356 keV and from 0.08 to 0.09 cm2/g at 662 keV. However, a slight increase was observed in the identified mass attenuation coefficients at (1172 and 1332 keV).
Purpose: In 2020, the franchise industry accomplished a significant growth compared to the previous year, as the number of franchise companies increased by 9.0% while the number of franchise brands increased by 12.5%. Despite growth in size, the Korean franchise industry underwent many negative incidents, such as franchise ownership sales to private equity funds, that led to deterioration of businesses. From this point of view, this study aims to make various proposals to help policy makers develop franchise industry policies by analyzing trends of the current and previous presidential administrations' franchise policies and regulations using newspaper articles. Research design, data and methodology: A total of 7,439 articles registered in Naver API from February 25, 2013 to November 29, 2021 were extracted. Among them, 34 unrelated video articles were deleted, and a total of 7,405 articles from both administrations were used for analysis. The R package was used for word frequency analysis, word clouding, word correlation analysis, and LDA (Latent Dirichlet Allocation) topic modeling. Results: The keyword frequency analysis shows that the most frequently mentioned keywords during the previous administration include 'no-brand', 'major company', 'bill', 'business field', and 'SMEs', and those mentioned during the current administration include 'industry' and 'policy'. As a result of LDA topic modeling, 9 topics such as 'global startups' and 'job creation' from the previous administration, and 10 topics such as 'franchise business' and 'distribution industry' from the current administration were derived. The results of LDAvis showed that the previous administration operated a policy based on mutual growth of large and small businesses rather than hostile regulations in the franchise business, whereas the current administration extended the regulation related to franchise business to the employment sector. Conclusions: The analysis of past two administrations' franchise policy, it can be suggested that franchisors and franchisees may complement each other in developing the Fair Transactions in Franchise Business Act and achieving balanced growth. Moreover, political support is needed for sound development of franchisors. Limitations and future research suggestions are presented at the end of this study.
The Russia-Ukraine War was a "three-layer compounded war" between the US and Russia, Russia and Ukraine, and Ukrainian government forces and rebels. First, the war is a phenomenon that occurred when the western sphere of influence seeking to maintain and strengthen the liberal international order and the Sino-Russian sphere of influence seeking a new alternative order collided in Ukraine, a geopolitical fault zone. Second, this war is the result of a typical 'security dilemma' phenomenon caused by the 'chain reaction' game of NATO's continuous expansion and Russia's response. Third, the Russia-Ukraine war was caused by the Russian military projection to prevent the military restoration of Donbas region by Ukraine. Until now, the Western world, led by the US, showed unexpected solidarity after the war despite subtle differences in positions. However, the non-Western world, including China, is not participating in the condemnation and sanctions against Russia. This war will be an important turning point in the existence and change of the current international order that has been formed and is operating since the end of the Cold War. The direction of maintenance/restoration, revision/change, and end/transformation of the current international order is highly likely to be determined depending on the development pattern and method of ending the war.

Objectives: The aim of this study was to evaluate the influence of peak kilovoltage (kVp) and a metal artifact reduction (MAR) tool on image quality and the diagnosis of vertical root fracture (VRF) in cone-beam computed tomography (CBCT). Materials and Methods: Twenty single-rooted human teeth filled with an intracanal metal post were divided into 2 groups: control (n = 10) and VRF (n = 10). Each tooth was placed into the socket of a dry mandible, and CBCT scans were acquired using a Picasso Trio varying the kVp (70, 80, 90, or 99), and the use of MAR (with or without). The examinations were assessed by 5 examiners for the diagnosis of VRF using a 5-point scale. A subjective evaluation of the expression of artifacts was done by comparing random axial images of the studied protocols. The results of the diagnoses were analyzed using 2-way analysis of variance and the Tukey post hoc test, the subjective evaluations were compared using the Friedman test, and intra-examiner reproducibility was evaluated using the weighted kappa test (α = 5%). Results: The kVp and MAR did not influence the diagnosis of VRF (p > 0.05). According to the subjective classification, the 99 kVp protocol with MAR demonstrated the least expression of artifacts, while the 70 kVp protocol without MAR led to the most artifacts. Conclusions: Protocols with higher kVp combined with MAR improved the image quality of CBCT examinations. However, those factors did not lead to an improvement in the diagnosis of VRF.
Purpose: The purpose of this study was to investigate differences in the control process to satisfy spatial and temporal constraints imposed upon the anticipation timing response by analyzing the effect of spatio-temporal accuracy demands on eye movements, response accuracy, and the coupling of eye and hand movements. Research design, data, and methodology: 12 right-handed male subjects participated in the experiment and performed anticipation timing responses toward a stimulus moving at three velocities (0.53m/s, 0.66m/s, 0.88m/s) in two task constraint conditions (temporal constraint, spatial constraint). During the response, response accuracy and eye movement patterns were measured from which timing and radial errors, the latency of saccade, fixation duration of the point of gaze (POG), distance between the POG and stimulus, and spatio-temporal coupling of the POG and hand were calculated. Results: The timing and radial errors increased with increasing stimulus velocity, and the spatio-temporal constraints led to larger timing errors than the temporal constraints. The latency of saccade and the temporal coupling of eye and hand decreased with increasing stimulus velocity and were shorter and longer respectively in the spatio-temporal constraint condition than in the temporal constraint condition. The fixation duration of the POG also decreased with increasing stimulus velocity, but no difference was shown between task constraint conditions. The distance between the POG and stimulus increased with increasing stimulus velocity and was longer in the temporal constraint condition compared to the spatio-temporal constraint condition. The spatial coupling of eye and hand was larger with the velocity 0.88m/s than those in other velocity conditions. Conclusions: These results suggest that differences in eye movement patterns and spatio-temporal couplings of stimulus, eye and hand by task constraints are closely related with the accuracy of anticipation timing responses, and the spatial constraints imposed may decrease the temporal accuracy of response by increasing the complexity of perception-action coupling.

In this study, the effect of an acidic treatment on granular activated carbon (GAC) and activated carbon fibers (ACF) was investigated for a $Pb^{2+}$ and $Ni^{2+}$ ion adsorption. 1.0 M nitric acid solution was used as the acid solution for the surface treatment. Surface properties of the GAC and ACF were characterized by the pH, elemental analysis and pHpzc (pH of the point of zero charge). Their specific surface area and the pore structure were also evaluated by the nitrogen adsorption data at 77K. As a result, the acidic treatment led to an increase of the oxygen-containing functional groups. Furthermore, the adsorption capacity of the acid-treated GAC and ACF was improved in the order of acidic-ACF > untreated-ACF > acidic-GAC > untreated-GAC, though the decrease in specific surface area induced by a pore blocking of the functional groups was observed.
The Eighteenth Century Shakespeare's Women Audiences: From Objects of Sexual Appetite to Ladies of Quality Abstract Younglim Han (Kyungpook National U) This paper aims to give an account of the eighteenth century Shakespeare's women audiences who marked a turning-point in the history of Shakespeare's popularity. The 1736 formation of the 'Shakespeare Ladies Club' as a leading group of the female audience encouraged the theater managers to perform more Shakespeare. Stage productions relied more than ever on the favorites of women audiences. The establishment of female patronage was associated with the popularity of Shakespeare's crossed-dressed comedies and actresses in 'breeches' part. The outstanding achievement of the Ladies was their contribution to the promotion of Shakespeare's status as an embodiment of British culture and the acknowledgement of the dignity of national literature. They were successful in securing the native sense of Shakespeare in place of Italian opera and Harlequin pantomime. The recognition of the national significance of Shakespeare led a campaign to erect his monument in Westminster Abbey. The female audience's claim to the respectable Shakespeare provided the stimulus for transforming his plays in the interests of family values such as marital duty and domestic morality. Marina (1738), George Lillo's adaptation of Pericles that was dedicated to the Ladies, was an exemplary case. The domestic versions of Shakespeare stressed the importance of women characters and the idealization of them. Thus the reception of Shakespeare in the eighteenth century was characteristic of formulating the women audiences-performers-characters association. The female yearning for a refined theater was a significant achievement, considering its influence on ways of establishing the canonical Shakespeare in the eighteenth century.
How should we conceptualize regions? What is the context in which new approaches to regional study take place? What is the role of historical change in the reconceptualization of regions or areas? This article addresses this issue by using two case studies to shed light on the history of regional study by comparing some of the ways in which the Middle East and Southeast Asia have been conceptualized. Accordingly, the discussion traces the ways in which these areas were understood in the 19th century by highlighting the ideas of a number of influential Victorian thinkers. The Victorians are useful because not only did British thinkers play critical roles in the shaping of modern patterns of knowledge, but their empire was global in scope, encompassing parts of both Southeast Asia and the Middle East. However, the Victorians regarded these places quite differently: Southeast Asia was frequently described as "Further India" and the Middle East was the home of the Ottoman Empire. Both of these places were at least partly understood in relation to the needs of British policy-makers, who tended to focus most of their efforts according to the needs of India-which was their most important colonial possession. The article exhibits the connections between the "Eastern Question" and end of the Ottoman Empire (and the political developments which followed) led to the creation of the concept of "Middle East". With respect to Southeast Asia, attention will be devoted to the works of Alfred Russell Wallace, Hugh Clifford, and others to see how "further India" was understood in the 19th century. In addition, it is clear that the successful deployment of the term "Southeast Asia" reflected the political needs of policy makers in wake of decolonization and the Cold War. Finally, by showing the constructive nature of regions, the article suggests one possible new path for students of Southeast Asia. If the characterization of the region is marked by arbitrary factors, it may actually point to a useful avenue of enquiry, a hermeneutic of expedience. Emphasis on the adaptive and integrative features of lived realities in Southeast Asia may well be a step beyond both the agendas of "colonial knowledge" and anti-colonial nationalism.
This study focuses on investigating the influence of epoxy polymer crosslinking density, a crucial aspect in composite material matrices, on the yield surface using molecular dynamics simulations. Our approach involved generating epoxy models with diverse crosslinking densities and subjecting them to both uniaxial and multiaxial deformation simulations, accounting for the elasto-plastic deformation behaviors. Through this, we obtained key mechanical parameters including elastic modulus, yield point, and strain hardening coefficient, all correlated with crosslinking conversion ratios. A particularly noteworthy finding is the rapid expansion of the yield surface in the biaxial compression region with increasing crosslinking ratios, compared to the uniaxial tensile region. This unique behavior led to observable yield surface variations, indicating a significant pressure-dependent relationship of the yield surface considering plastic strain and crosslinking conversion ratio. These results contribute to a deeper understanding of the complex interplay between crosslinking density and plastic mechanical response, especially in the aspect of multiaxial deformation behaviors.
