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.

본 연구는 해외여행 중에 발생하는 관광객 스트레스에 관한 실증연구로 그동안 드물게 연구되어 왔다. 해외여행 중 인지되는 스트레스의 원인이 관광객 가치관, 목적지 그리고 여행형태와의 관계를 조사하는데 목적을 두었다. 본 연구의 중요 변수들로는 1)목적지 국가, 2)관광객 가치관, 3)여행형태, 4)관광스트레스의 원인으로 구분되었다. 분석을 위해 SPSS 12.0 가 이용되었으며 요인분석, 판별분석, 군집분석 그리고 분산분석을 사용되었다. 연구 결과, 제시된 중요변수(목적기, 가치관, 여행형태)들과 스트레스 간에 유의한 차이를 발견하였다. 특히 관광객의 가치관과 여행형태는 해외 여행중에 발생하는 스트레스와의 관계에서 유의한 영향을 주는 것으로 나타났다. 본 연구 결과가 관광산업에 긍정적인 영향으로 반영될 수 있다면 여행객들은 여행을 통해 보다 즐겁고 안전한 여행이 될 수 있을 것으로 판단된다.

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.

최근 고령인구 증가와 장기요양 보험의 도입으로 요양기관에 입주하는 고령 환자의 수가 빠른 속도로 증가하고 있다. 이러한 장기요양 환자들은 만성질환과 치매 등의 질환을 앓고 있어 거동이 불편하거나 인지력이 떨어지는 어려움을 겪을 뿐 아니라, 가족과 떨어져서 우울증에 시달리므로 심리 및 정서적인 지원이 절실하다. 그리하여, 본 논문에서는 거동이 불편한 고령 환자를 위하여 VR과 포톤네트워크를 이용하여 물리적으로 떨어져 있는 가족들과 함께 평소에 가보지 못했던 해외여행 체험을 가상으로 제공하고자 한다. 기존 VR을 이용한 여행체험 서비스는 혼자 체험하는 반면, 제안하는 콘텐츠는 포톤 네트워크를 통해 가족 및 친구들이 네트워크로 참여함으로써 여행 체험 시 대화는 물론 지인들의 옆모습을 보며 함께 경치를 즐길 수 있다. 이를 통하여 고령의 장기 요양환자로 하여금 심리적 안정감을 회복하고 치유의 의지를 높여서 투병생활에서 삶의 질을 높이는데 도움을 줄 것이라 기대한다.

최근 지역 문화 발전과 도시 다양성의 맥락에서 각각의 관광지들은 독특한 민속 문화를 발굴하여 관광객의 관심과 방문을 유도하고 있다. 지속 가능한 관광의 일환으로 미식 관광은 명승지 환경을 해치는 건설을 할 필요도 없고, 지역 주민과 관광객에게 서비스를 제공하기 위한 시설 개선 만하면 되는 장점도 있다. 그러나 기존의 미식 관광은 관광객을 풍속 현장에만 두게 되어 주체 간에 다른 문화적 차이를 넘어 민속 문화의 핵심을 체험할 수 없었다. 본 논문은 관찰 방법, 융복합 주제 연구 및 사례 연구를 통해 민속 문화를 이해하는데 있어서 푸드 도슨트 가이드 투어의 역할을 연구하였다. 특히 도슨트 가이드 투어에서 미식 관광이 지속 가능 발전이라는 목표를 잘 달성할 수 있도록 가이드가 관광객들로 하여금 민속 문화의 핵심에 보다 효과적으로 동화되어 체험할 수 있도록 돕는 방법을 연구하였다.

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.
