Background: In this study, the measurement of job stress of electric overhead traveling crane operators and quantification of the effects of operator and workplace characteristics on job stress were assessed. Methods: Job stress was measured on five subscales: employee empowerment, role overload, role ambiguity, rule violation, and job hazard. The characteristics of the operators that were studied were age, experience, body weight, and body height. The workplace characteristics considered were hours of exposure, cabin type, cabin feature, and crane height. The proposed methodology included administration of a questionnaire survey to 76 electric overhead traveling crane operators followed by analysis using analysis of variance and a classification and regression tree. Results: The key findings were: (1) the five subscales can be used to measure job stress; (2) employee empowerment was the most significant factor followed by the role overload; (3) workplace characteristics contributed more towards job stress than operator's characteristics; and (4) of the workplace characteristics, crane height was the major contributor. Conclusion: The issues related to crane height and cabin feature can be fixed by providing engineering or foolproof solutions than relying on interventions related to the demographic factors.

Modern military equipments are often required to be mounted on a truck for their survivability and operation performance. Special units installed on the truck at times experience serious shock vibration caused by obstacles of road and/or uncommon road shape. It is then essential to analyze the travel performance of truck-mounted special units for their survivability and performance. In this paper, shock responses of the equipments subjected to bump passing and wash board road are experimentally obtained and also analyzed via FEM. Modified bump configuration and road profile considering the interface with tire are suggested. Analytical results considering this modification show good agreement with test results.

The Republic of Korea is rapidly entering an aging society. With the aging of society, the overseas travel of the elderly is increasing rapidly. According to the Korea Tourism Organization, the number of overseas tourists aged 61 or older last year exceeded 2.5 million, of which over 80 were over 200,000. Age is no longer a limiting factor for traveling abroad, but traveling to unfamiliar places is certainly a challenge. Old people may experience a variety of problems, so special care should be taken. In particular, the aircraft cabin environment is different from the ground, so elderly travelers with respiratory or heart disease require special attention. In this paper, we want to know the precautions and how to prepare for the safe air travel for the elderly.

Little research has been done regarding the issues of tourist stress in overseas traveling. Thus, this study investigated what causes travel stress and to what level of stress that overseas tourists experience. The key variables of this study were 1) destination country, 2) tourist value, 3) types of travel, and 4) causes of travel stress. For the analysis of this study, SPSS 12.0 was used which included Factor analysis, Discriminant analysis, ANOVA and Cluster analysis. The findings of this study suggest that there is a correlation between the level of travel stress and the other variables such as travel destination, tourist value, and types of travel. Especially, tourist value and types of travel significantly affect travel stress. Based on the findings, this study suggests that tourism industry should take proper steps in order to make overseas traveling more enjoyable.

In this paper, we consider the maximum scatter traveling salesman problem (MSTSP), a travelling salesman problem (TSP) variant. The problem aims to maximize the minimum length edge in a salesman's tour that travels each city only once in a network. It is a very complicated NP-hard problem, and hence, exact solutions can be found for small sized problems only. For large-sized problems, heuristic algorithms must be applied, and genetic algorithms (GAs) are found to be very successfully to deal with such problems. So, this paper develops a hybrid GA (HGA) for solving the problem. Our proposed HGA uses sequential sampling algorithm along with 2-opt search for initial population generation, sequential constructive crossover, adaptive mutation, randomly selected one of three local search approaches, and the partially mapped crossover along with swap mutation for perturbation procedure to find better quality solution to the MSTSP. Finally, the suggested HGA is compared with a state-of-art algorithm by solving some TSPLIB symmetric instances of many sizes. Our computational experience reveals that the suggested HGA is better. Further, we provide solutions to some asymmetric TSPLIB instances of many sizes.

Recently, the number of elderly people residing in nursing homes has increased rapidly due to the increase in the elderly population and the introduction of long-term care insurance. These long-term care patients suffer from chronic illnesses and dementia, and thus suffer from inconveniences or lack of cognitive ability. Thus, psychological and emotional support is urgent because they are depressed away from their families. Therefore, in this paper, we aim to provide a virtual experience of overseas trips by using VR and Photon networks for elderly patients with mobility difficulties. Existing VR-based travel experience service is doing alone, but the proposed contents can enjoy the scenery together with the view of the family member as well as the conversation during the travel experience. It is expected that the elderly patients with long - term care will be able to restore their psychological stability and improve their willingness to heal and improve their quality of life from the proposed application.

Under the background of regional cultural development and cities' diversity, various tourist destinations attract tourists' attention and visit by mining their unique folk culture. As a part of sustainable tourism, gastronomy tourism can provide residents and tourists services only by improving the residents' facilities without damaging the environment. However, the existing gastronomy tourism only makes tourists in the folk scene, and tourists can not overstep the cultural differences caused by intersubjectivity to experience the core of folk culture. This paper attempts to use the observation method, cross-subject study, and case study to study the role of food docent-guided tours in understanding folk culture. Moreover, the docent-guided tour studies how the docent can help tourists go deep into the core of folk culture better to realize the sustainable development goal of gastronomy tourism.

Recently with increasing interest in the natural science history education, a lot of natural science museums have been developed in various locations. This project is located in one of the biggest Paleozoic site, Taebak Kangwon-do. This kind museum has had important rolls in terms of education for student, destination for traveling and reservation of important holdover of the old ages. To do those kind of parts, this project has been designed with concepts and themes like; i. being organized with story telling structure with theme "secret of life and earth from Taebak" ii. combining experiences between outdoor experimental search for the real fossils and indoor educational interactions with real size model and moving films. iii. designing with strong identities of Paleozoic era. For the design identities the outer appearance was designed with motive of trilbites in an abstract way and inside was finished with exposed concrete and various size of moving films projected to walls and floor to emphasize real scale experience of the old ages.

Social media has been integrated into a part of travel industry. Subsequently, it has influenced tourists' travel behavior. Prior studies claim that individuals have different behaviors regarding the use of social media for travel purposes. With lack of studies focusing on age group, the objective of this study is to determine whether there is a difference in the motivation among three generations in using social media for the sake of sharing travel experiences. Finding shows that all generations use social media with similar motivation for travel purposes. They have high motivation in obtaining travel information before the trip and in sharing memorable travel experiences through social media. They also wanted to keep such information as personal document during and after the traveling.

This study examined how Ji-Won Park(Yeonam) created the eaning of things based on the epic of self and how his travel experience manifested on the epic of self. First of all, the author examined that how Yeonam interpreted the meaning of things based on his own reflection using the examples of "The Golden Arbor" and "Baeki-Sukje." As a result, the author found that Yeonam focused on the material value of "the Golden Arbor" rather than the reason of creation of "The Golden Arbor." Yeonam also used "Baeki-Sukje" as an ironic representation rather than the original meaning of loyalty and integrity. Second, it helped to present personal self epic since travel experience and the atmosphere of the travel journey could reduce the pressure from the epic of society on individuals. For instance, when Ji-Won Park (Yeonman) traveled the China (the country of Chung) where society promoted public welfare, Yeonman was able to express himself freely which showed utilitarian over justice. Finally, the author talked about how a book of travels can be used for the case of literature therapy since "Yeulhailgi" was written by Yeonam while he was traveling. The author indicated that it might be useful for the patients to write own travel journey since the therapist could analyze the mind of patients by the epic of self. In addition, using a book of travels also can be valuable for the patients since the therapist could analyze the condition of patients as well as help patients see through themselves while reading a book of travels.
