  • Purpose: The purpose of this study is to identify the causes of odors generated in traditional markets and to suggest appropriate application technologies to solve them. Research design, data and methodology: In order to achieve the purpose of this study, complex malodors, TVOC, and hydrogen sulfide were measured three times at each point in Wonju-city, Gangwon-do using direct-reading odor measuring equipment in Joong-ang Traditional Market's Korean beef Alley, Sundae Alley, and Joong-ang Citizens Traditional Market. Therefore, the average value was compared with the emission standard and analyzed. Results: As a result of the study, complex malodors exceeded the emission standards at all points, and hydrogen sulfide exceeded the emission standards at all except for one point. Conclusions: The odor generated in the traditional market has various causes and low concentration, so it is necessary to reduce the odor by using an appropriate technology.

  • The purpose of this paper is to find out the identity and succession of traditional Hanok villages by analyzing the location, layout, and spatial organization of neo-Hanok Village, which was built in Korea. So far, neo-Hanok Village has not prepared a specific institutional mechanism despite the government's support and growing public interest. In addition, the purpose of neo-Hanok Village has not been verified, even though it was built all over the country for the purpose of the dignity and succession of the traditional Hanok Village. This study examines how the spatial organization elements of the traditional Hanok Village are planned according to the design principles of the old literature and applies them to the neo-Hanok Village to determine the succession of the traditional Hanok Village.

  • Recently, many countries around the world began to show interest in safety against terrorism, fire, and natural disasters. This study aimed to propose a quantitative measurement system for emergency evacuation and safety for various kinds of terrorism and fire within high-rise multi-purpose facilities, which can measure the pedestrians' ordinary walking patterns in the concourse with the highest pedestrian volume out of all the spaces within multi-story buildings, predict pedestrians' evacuation walking lines when a sudden disaster breaks out, and analyze the gait coefficient, occupant density, and evacuation behavior time.

  • Hemifacial spasm (HFS) is due to the vascular compression of the facial nerve at its root exit zone (REZ). Microvascular decompression (MVD) of the facial nerve near the REZ is an effective treatment for HFS. In MVD for HFS, intraoperative neurophysiological monitoring (INM) has two purposes. The first purpose is to prevent injury to neural structures such as the vestibulocochlear nerve and facial nerve during MVD surgery, which is possible through INM of brainstem auditory evoked potential and facial nerve electromyography (EMG). The second purpose is the unique feature of MVD for HFS, which is to assess and optimize the effectiveness of the vascular decompression. The purpose is achieved mainly through monitoring of abnormal facial nerve EMG that is called as lateral spread response (LSR) and is also partially possible through Z-L response, facial F-wave, and facial motor evoked potentials. Based on the information regarding INM mentioned above, MVD for HFS can be considered as a more safe and effective treatment.

  • The purpose of this study is to investigate the effect of the elderly's motivation to participate in ball games In order to clarify the purpose of this study, leisure sports participants over the age of 20 residing in the Jeonnam region in 2020 were selected as the population. In addition, 150 males, 150 females, and 300 total subjects were selected using the convenient sampling method. In addition, as a survey tool, a questionnaire was used centering on the motivation for participation in leisure sports, exercise commitment, and quality of life, and the data collected using this was processed statistically according to the purpose of analysis using SPSS 20.0 version. The results obtained through this research process are as follows. First, it was found that the motivation to participate in leisure sports has a partial effect on exercise commitment. Second, it was found that the motivation to participate in leisure sports partially affects the quality of life. Third, it was found that the commitment to exercise in leisure sports has a partial effect on the quality of life.

  • Destination marketing organizations (DMOs) utilize the official website for marketing and promotional purposes, while tourists often navigate through the official website to gather necessary information for their upcoming trips. With the advancement of business analytics, DMOs may need to exploit the clickstream data generated through their official website to develop more suitable and persuasive strategic marketing and promotional activities. As such, the primary objective of the current study is to show whether clickstream data can successfully identify the trip purposes of a particular user. Using a latent class analysis and multinomial logistic regression, this study found the meaningful and statistically significant variations in webpage visits among different trip purpose groups (e.g., weekend getaways, day-trippers, and other purposes). The findings of this study would provide a foundation for more data-centric destination marketing and management practice.

  • Purpose: The purpose of this study is to find factors affecting the acceptance intention of autonomous mobility service by applying the unified technology acceptance theory(UTAUT). Methods: The measurement items for each component of this study were modified to meet the purpose of the study by referring to previous studies related to mobility based on UTAUT, which has secured validity and reliability in many studies. The collected data through the online survey were analyzed using hierarchical regression analysis. Results: It was found that performance expectation, effort expectation, social influence, and facilitation conditions for autonomous mobility service had a positive effect on acceptance intention. Also, in this relationship, it was confirmed that driving experience moderated the relationship between performance expectation and acceptance intention, and between effort expectation and acceptance intention. Conclusion: Understanding the public's acceptance of autonomous mobility services, and suggesting strategic implications for the direction of service development to companies that are pushing to enter the autonomous mobility service market.

  • Purpose: The purpose of this research was to examine the effect of the sensoryscape (sport fans' stadium experiences via the five senses) on connectedness and elation that sport fans have about their teams. Research design, data, and methodology: To achieve this purpose, structural equation modeling was conducted with a total of 417 KBO baseball fans. Results: The results of the research are as follows. First, stadium experiences via sport fans' sight, sound, and touch had positive effects on connectedness that consists of passion, nostalgia, supportive, and connected. Second, stadium experiences via sport fans' sight, sound, and taste had positive effects on elation that consists of happy, excited, pleased, proud, optimistic, and entertained. Conclusions: This research provides the first empirical evidence of the effects of sport fans' sensory experiences on emotions associated with sport teams. In order to maximize connectedness and elation that sport fans have about their teams, sport marketers need to develop specific sensory strategies that affect stadium experiences. Further implications were discussed.

  • Test devices can perform various functions, such as research on detection targets, sensors that detect detection targets, combined products containing sensors, and certification for the launch of combined products. However, the scope of use of test devices is limited because they perform only a single role or could only serve a particular purpose in the past. Therefore, studies on test devices that can perform various functions, such as research on detection targets, sensors that detect detection targets, combined products containing sensors, and certification for the release of combined products are necessary. Accordingly, this study proposes a test device that can increase the scope of use in the technical field of electric fires. In addition, we examine various outcomes of the proposed test device.
