This study is for analyzing the management performances of Korean tourism firms, which have been operating as preparing strategically against FTA, one of the most importantly external environment in international management since in the middle of 1990s. The main purpose can be mentioned to test empirically some relations between the management performances of Korean tourism ones and the levels of understanding and preparing against FTA. In detail speaking, the dependent variables of management performances are classified with sales, profits and management satisfaction, while the independent ones regarding with FTA are sorted based on the previous studies with the 2 following factors like understanding/preparing of managers and one of workers in a firm. This study is conducted in two stages. Firstly, the research model is designed by the reviewing relevant theories, previous studies. Secondly, the survey of Korean tourism enterprises engaging in management activities in Korea is implemented by collecting questionnaires. And for testing the hypothesis, the analyzing tools are being used for correlation, reliability, validity and multi regression on SPSS 12.0 for windows and finally the path analysis of structural equation modeling is activated with AMOS 7.0 for windows.

This study is about the origin of Toigye's SaDanChilJeongRiGiHoBalRon (四端七情理氣互發論: theory of humanity and the relation between humanity and heaven's principle). In this study, I looked into the influences of Toigye's elders on such theory of Toigye. In this process, I introduced SimHakJangGuJipJuDaeJeon (心學章句集註大全) I obtained recently as a main material. This book was written by an uncelebrated scholar born in 60 years before Toigye. It showed "SaDanRiBalYiGiSuJi ChilJeongGiBalRiSeungJi (四端理發而氣隨之 七情氣發而理乘之)", which was as same as Toigye's study logic. Regarding the fact that such two logics were same, I traced the transferring path of such logic weighing the possibility of transferring such book or HoBalRon shown in such book while not completely neglecting an accidental coincidence. I also induced that the pro-Toigye-era also had the academic circumstance under which RiGiHoBalRon could be born even supposing an accidental coincidence. In addition, I also emphasized that such book was positioned to pioneer Toigye's neo-Confucianism in various aspects.

The yield potential of sesame depends on genetic factor, environmental factor, genetic × environmental interaction, as well as agronomic factors such as sowing date, planting density or seed rate for sowing. The main aim of this study was to analyze the effects of different sowing dates on the yield-related traits and total seed weight of sesame. The analysis of variance revealed that different sowing dates affected sesame yield-related traits such as plant height, number of branch per plant, number of capsule per plant, 1,000-seed weight, and total seed weight. Early or late sowing date showed negative effect of yield-related sesame traits and total seed weight. Optimum sowing date for sesame in the middle region of Korean peninsula was May 10^th, in which total seed yield recorded 90 kg per 10 are. Path-coefficient analysis revealed that the number of capsule per plant and plant height were major factors that affected the total seed weight of sesame across different sowing dates.

This study conducted a questionnaire survey on 280 people who had experience of using mobile augmented reality-based online concerts. Using the SPSS 21.0 and AMOS 21.0 programs, the factors affecting the intention to reuse were investigated through statistical analysis(correlation analysis, path analysis, etc.). The main results are as follows. First of all, Presence and interactivity had a positive effect on flow, perceived ease of use and perceived usefulness. Flow had a positive effect on perceived ease of use and perceived usefulness. Perceived ease of use had a positive effect on perceived usefulness, and perceived usefulness had a direct positive effect on intention to reuse whereas perceived ease of use had an indirect effect on intention to reuse through perceived usefulness. In order to increase the intention to reuse of the mobile augmented reality-based online concert, it is necessary to prepare a plan to increase the level of presence, interactivity, and flow experienced by users. This study identified factors that affect the intention to reuse online concerts based on mobile augmented reality in an untact society. Therefore, it will be meaningful in that it presents the implications necessary to prepare a plan that can be efficiently accepted by consumers for the rapidly growing mobile augmented reality-based online concert.

Purposes: The convenience of smartphones have lead to people's overdependence on devices, which may cause obstacles in daily life. It is useful to manage smartphone overdependence by using mobile health applications. We aimed to investigate the acceptance of mobile health applications designed to help in the management of smartphone overdependence. Methodology/Approach: We developed the extended model based on the Unified Theory of Acceptance and Use of Technology 2. The modified model had six hypotheses with six variables: result demonstrability, performance expectancy, effort expectancy, social influence, perceived risk, and behavioral intention to use. We randomly included 425 smartphone users in an online survey in 2020. A structural equation model was used to estimate the significance of the path coefficients. Findings: Performance expectancy and social influence had a very strong direct positive association with behavioral intention to use. Result demonstrability had a direct positive association with performance expectancy. Perceived risk had a strong direct negative association with performance expectancy. Performance expectancy and social influence were the main factors directly influencing the acceptance of mobile health applications for the management of smartphone overdependence. Practical Implications: We demonstrated smartphone users' acceptance of mobile health applications for smartphone overdependence management. Based on these results, we could develop mobile health applications more effectively.

River-side Embankment collapse involves various causes. The embankment collapse due to internal erosion around embedded structures reaches up to more than 10% in Korea. Many studies are being attempted to prevent from the collapse of the embankment rooted from overtopping and instability as well as internal erosion. One of them is the study on the application of biopolymers. The application of biopolymers to soils are divided into enhancing strength, vegetation and erosion resistance. This study investigated the effect of biopolymer treated soil on erosion resistance. The main goal of the study is to obtain basic data for real-scale experiments to verify the effectiveness of biopolymer treated soil embankment including a review of the collapse pattern in the model embankment with various test conditions. The optimized experimental conditions were selected by examining the erosion patterns according to each induction path with three compaction degree of the model embankment. As a result of the experiment, the internal erosion rate in the embankment to which the biopolymer treated soil was applied is greatly reduced, and it could be concluded that it might be applied to the actual embankment. However, in this study, the conclusion was drawn only within the scaled-down model embankment. In order to practically apply the biopolymer treated soil to the embankment, the study considering the scale effect would be needed.

Although market stabilization measures have been triggered in the K-ETS, carbon price is still under uncertainty. Considering Korea's 2030 enhanced reduction target announced in October 2021, it is crucial to have practical stabilization measures to appropriately deal with price uncertainty. This study examines the quantitative effects of a price collar, which is considered as a means of alleviating price uncertainty, on expected cumulative emissions and abatement costs. There are three main scenarios: carbon tax, emissions trading system, and emissions trading system with a price collar. Monte Carlo simulation was conducted to reflect uncertainty in emission. There are several results as follows: 1) In a price collar, domestic emission target is likely to be achieved with a lower expected abatement cost than other scenarios. In addition, there is a small amount of excess emissions in this research and it would be not critical(0.1% excess than target); 2) Prohibiting banking increases the expected abatement cost. This is because firms can not intertemporally reallocate allowances to match the firm's optimal emissions path; 3) With the adoption of a price collar, government's net revenue can be positive even if the government's purchase volume of emissions allowances is more than sales volume. This is because the government sells them at price ceiling and purchases them at price floor.

Effective acquisition technology is an important factor determining the competitiveness of companies(Roxas et al., 2011). Since the importance of technology transfer has been increased, there has been a growing interest in company, government, university and research institutes (Bozeman et al., 2015). Despite the national efforts for activating technology transfer, a lot of technology is still in universities and R&D center(Ockwell et al., 2009). The barriers of technology transfer are a main reason to inhibit the technology transfer. In order to be lower technology transfer barriers, it is necessary to derive the technology transfer broker based on social network analysis. However, most studies related to technology transfer broker had been focused on empirical study(Bozeman et al., 2015). Therefore, it is needed to suggest the method to grasp the opportunity that can lead to technology innovation based on analyzing and visualizing the network of technology transfer. The method in this study provides the company with the connectable path, technology transfer broker and strategy to classify the technology actor within the network. Finally, the method is applied to Global MVP for verifying the feasibility of method.

This study conducts a theoretical research on road traffic noise. Also, the domestic road noise forecast models were compared each other and analyzed with advanced countries' models to indicate the application possibility and problems. For the establishment of a general formula, we compared the forecasted value with the actual value applied in the formula proposed by the National Environment Institute, and examined the necessary improvement of the domestic road traffic noise forecast model. Also, a regression model was built to examine the relationship between traffic factors and noise. The traffic volume and speed are the main traffic factors used in this formula to affect the noise. From the results, it was found that the speed had a closer relationship with the noise rather than the traffic volume. Therefore, to decrease road noise, it is more important to control traffic speed. The spatial effect of road traffic noise within the apartment complexes was used in the case study to derive location-specific adjustment values. We surveyed the road traffic noise of three apartment complexes, and found that the road traffic noise within each complex was affected at plane level as well as at three-dimensionally. In other words, as the distance from the sound origin grows farther, noise level decreases. Also, it was found that noise increases as heigt goes up, but drops when the height goes beyond a certain level, and that the effect of noise decreases if there are obstacles along the path of the noise direction. Therefore, apartment site design should be done with consideration of the effects of noise in the future.
