Purpose: Non-Fungible Token (NFT) ART, based on NFT technology, represents a novel form of art that has recently garnered significant attention in the art market. NFT technology enables the assertion of ownership over digital data, introducing the concept of ownership into the digital realm. As digital data gains ownership, NFT ART is anticipated to be positively viewed as an investment and expected to become more active due to the characteristics of this new technology. Therefore, this study aims to verify the influence of NFT ART characteristics on perceived value. This study contributes to extracting the distinctive characteristics of NFT ART compared to other forms of art and to understanding the perceived value of NFT ART among consumers with purchasing experience. Methods: This study applied structural equation modeling to explore the relationships among the variables using SPSS 26.0 and R program version 4.2.3. A total of 320 questionnaires were retrieved, all of which were adopted as valid analytical samples without missing values. Results: The findings indicate that the decentralization, transparency, and scarcity of NFT ART positively influence the perceived usefulness and enjoyment among consumers, while security does not have a significant impact. This suggests that higher levels of decentralization, transparency, and scarcity in NFT ART enhance perceived usefulness and enjoyment for consumers, significantly influencing the perceived value. Furthermore, it was confirmed that these characteristics are considered important values and perceptions from the consumer's perspective. Conclusion: The research presents positive factors for the activating of purchases among consumers considering buying NFT ART. It emphasizes the necessity of benefits for all participants to activate the art market. Additionally, the perceived value provides crucial insights for inducing active purchasing behavior in the NFT ART market and serves as a foundational study for further research.

Die soeben entwickelten Grundgs$\ddot{a}$tze k$\ddot{o}$nnen dazu f$\ddot{u}$hren, dass es bei Fluggesellschaften zum Abschluss mehrerer Tarifvertr$\ddot{a}$ge $\ddot{u}$ber Personalvertretungen durch verschidene Gewerkschften kommt. Dies leitet schlie${\ss}$lich zu der bereits angesprochenen Problematik der Tarifkonkurrenz $\ddot{u}$ber. Tarifkonkurrenz zeichnet sich bekanntlich dadurch aus, dass f$\ddot{u}$r dasselbe Rechtsverh$\ddot{a}$ltnis dieselbe Regelungsmaterie durch mehr als einen Tarifvertrag geregelt wird. Eine solche Tarifkonkurenz kann unabh$\ddot{a}$ngig von der Frage, ob Regelungsgegenstand betriebsverfassungsrechtlicher Normen ein betriebliches Rechtsverh$\ddot{a}$ltnis ist, auch bei dieser Art von Tarifnormen auftreten. Dabei betriebsverfassungsrechtlichen Kollektivnormen gem$\ddot{a}{\ss}$ $\S$3 Abs. 2 TVG die Tarifbindung des Arbeitgebers f$\ddot{u}$r die Anwendungsbarkeit gen$\ddot{u}$gt, wird beim Vorhandensein mehrerer solcher Tarifvertr$\ddot{a}$ge h$\ddot{a}$ufig pauschal von einer in jedem Fall aufzul$\ddot{o}$senden tarifkonkurrenz gesprochen. $\ddot{U}$berschneiden sich die Geltungsbereiche mehrerer Tarifvertr$\ddot{a}$ge $\ddot{u}$ber personalvertretungsrechtliche Fragen der im Luftbetrieb t$\ddot{a}$tigen Besch$\ddot{a}$ftigten und handelt es sich nicht um textidentische Regelungen, f$\ddot{u}$hrt indes kein Weg daran vorbei, dass eine Tarifkonkurenz besteht, die einer Aufl$\ddot{o}$sung bedarf. Die Rechtsprechung hat sich zur speziellen Fragen der Aufl$\ddot{o}$sung einer Konkurrenz betriebsverfassungsrechtlicher Tarifnormen soweit ersichtlich noch nicht ge$\ddot{a}$u${\ss}$ert. Nicht zuletzt aus diesem Grund wird in der Literatur ein buntes Spektrum an L$\ddot{o}$sungen pr$\ddot{a}$sentiert, wobei sich die meisten neueren Stellungnahmen vor allem mit Organisationstarifvertr$\ddot{a}$gen im Sinne von ${\S}$3 BetrVG besch$\ddot{a}$ftigen.

This study explores the trajectories of institutionalization for technology transfer both in the U.S. and Korea, particularly focusing on two universities: Korea Advanced Institute of Science and Technology (KAIST), and the University of California (UC). By comparing the diverging paths of the two universities in setting up institutions, this paper examines the limits of and lessons for technology transfer policies both to Korean government and universities in Korea. The University of California was involved in designing rules and codes, on one hand, to stimulate its members' engagements with technology transfer activity and, on the other hand, to keep its academic integrity since, no later than, the 1960s. The efforts and consequences range from its rules of patenting system to its codes of conducts. Through making rules formal and resolving conflicts on technology transfer activity, the U.S., and the University of California have decreased uncertainties for its members' engagements with industries. By contrast, KAIST has not built up such range of rules or codes due to its shorter experience and its constraining legal contexts. Korea introduced the legal format of the US Bayh-Dole Act in 2002, and its central government has led the initiatives for technology transfer, not allowing much latitude for its universities. This study implies a set of policy recommendations to the Korean government and KAIST: to build entrepreneurial universities, the government should give greater latitude to universities, so universities should be more rigorously engaged in developing their own rules and routines; the government, rather, should focus on providing bridging R&D funds like the Small Business Innovation Research (SBIR), so researchers could draw on resources to move their basic research into next phases; KAIST would be better to promote its members to engage with industries, and introduce conduct codes that allow its academics to engage in industrial activity, rather than building up its commercialization facilities.

The global economy is rapidly changing by technological innovation and diffusion of knowledge across nations. Therefore it is still important issue to find a major variables for convergence and divergence of economic development. The studies up to present on the relationship between innovation and institution has limitations that they have dealt with this issue only in term of cross-sectional study or mathematical research models. This paper aims at analyzing the impact of innovation capabilities and institutional quality on the economic growth. Empirically this paper will explore the relationship among human capital capacity and FDI, R&D expenditures and innovation capabilities and institutional quality. This paper analyzes 64 countries, which were divided into 4 groups depending on the level of economic development. Based on the data from 1995 to 2011 and by using a panel model, we look at the structural implications of the research questions. According to our analysis, the weight of R&D and the innovation capabilities were identified as important determinants of economic growth, and FDI was significant factor for economic growth in the upper middle group countries. In case of the innovation capabilities of countries, the diffusion and openness of innovation were most meaningful variables for economic growth. Also, institutional quality has a significantly positive impact. However, in the low-level economic group, innovation capabilities and institutions have a negative impact on economic growth. This paper identifies an important policy implications that of national innovation and institutional factors should be properly invested in accordance with the level of a country's economic growth.

Road traffic noise is closely related to road traffic environment, including traffic volumes by type and travel speed. In this study, we stated some issues and analyzed the relationships between road traffic noise and traffic flow characteristics. First, in attempt to find the answer to the question "When does the loudest traffic noise occur?" we reviewed the issue in the terms of traffic flow. As a result of analyzing level of service through Korea Highway Traffic Noise model, the actual maximum noise occurred in level of service D rather than level of service E, on the capacity state. It shows that maximum noise would be most likely to occur right before and after the peak hours. Second, this paper was looking for the method of a more easy and accurate traffic speed estimation to predict traffic noise. This paper proposed sketch planning techniques of speed-volume curve by level of service on Korea Highway Capacity Manual. As a result of trend line modeling, it was judged that quadratic form is a suitable function, and coefficient of determination ($R^2$) was higher than 0.96, respectively.

As gas hydrate is recently emerging as a new energy source to solve environmental and exhaustion problems caused by fossil energy, Korea is working on a gas hydrate development project under a 10-year plan from 2005 to 2014. Gas hydrate is expected to have a big effect on the economy and society of Korea, which is largely depending on energy imports besides water energy and atomic energy. However, it is uncertain whether the project will produce successful results. Thus, it is very important to improve its validity and to propose effective execution strategies by evaluating the value of the project in advance. Thus, this study intended to include new information, which had not been evaluated in existing methods, and to reduce biases or errors in value evaluation results by applying a fuzzy risk analysis to the real option model in order to evaluate the value of a gas hydrate development project. It is advantageous that the real option model based on the fuzzy risk analysis modelizes the vagueness and inexactness of intangible element judgment into an appropriate language scale so as to evaluate these elements clearly and integrate them with estimated financial performance results. The application of the fuzzy risk analysis makes it possible to conduct an analysis by dissolving a decision-making issue with complicated and various attributes into several simplified problems. With the continuing high oil prices and today's demand of clean energy, the necessity of energy resources and technology development projects keeps growing. Amid this situation, it is expected that these study results will contribute to proposing a guideline not only for gas hydrate projects but also for policy decision-making related to future energy industries.

In Korea, the game software and service industry is the core cultural industry from it's significant academic and policy. However, recent growth is slowing down because of increasing competition in the industry. In other words, most of the companies growth have reached limit caused by focusing only on short-term revenue-generating management, Therefore, the game software and service companies are needed to emphasize strategic planning of R&D and product development based on the long-term perspective. The purpose of this analysis is to measure the efficiency of management by data envelopment analysis(DEA), using data from 20 companies in the game software and service industry. Input variances are number of labor, total asset, and total investment and output variances are total sale and enterprise value. The results are followings: First, There was a different efficiency between the companies in the game software and service industry. The eight companies was inefficiency. Second, six inefficiency companies were excessive number of the employees and investment assets. third, four companies were CRS, five companies were IRS and eleven companies were DRS. From the result, five companies have to increase the scale of input variance and eleven companies also have to improve efficiency of input variance.
