여름은 여행이 많은 계절이고 운전을 하는 경우가 많기에 허리통증을 호소하는 사람들이 늘고 있다. 장시간 주행을 하다보면 운전자들은 한 자세로 고정되어 있어 혈액순환이 잘 안되어 목과 어깨에 무리가 따르게 되고, 허리가 아프며 가속과 정지를 많이 하게 되어 다리에 피로감을 느끼게 된다. 따라서 장거리 운전 중에도 차안에서 할 수 있는 간단한 스트레칭과 여행 중의 피로를 풀어주는 스트레칭으로 피로를 풀어보자.

This study is to measure traveling experience of bike riders whom going long distance trip. Bike paths and bike riding are crucial element for modern people's life style. At the same time, a bicycle trail is being developed by the National Bicycled-Oriented Chair Plan, which was established in 2009 by the National Bike Policy Master Plan. 13 million bike riders in Korea is keep on trying the long distance bike trip and its number is increasing every year. Accordingly, the Ministry of Public Administration and Security decides to promote the convenience of riders by developing bicycle app for long distance rider. The study attempted to assess usability of this app with 39 bike applications whom currently using the bike application. Afterwards, the researchers tests 11 hypotheses through in-depth interviews of six activated members. In sum, Bicycle travelers should be provided with bike trail guidance based on theme section skill, provided in-time speed distance related information, communicated with other bike riders, given tips for bike supplies and maintenance, and provided English language service. The study hopes to help find a customized service for bike travelers.

This study aims to investigate dynamic properties of express buses in the very low frequencies which affect motion sickness incidence. Since passengers often use express buses for long distance traveling, it is a critical point whether a give rise to motion sickness or not. In the study accelerations at the three points on the floor of the six test vehicles were measured during the driving at constant speeds. By applying frequency weighting curves suggested in ISO 2631-1 and ISO 2631-3, physical amount of accelerations were changed into perceptual amount which determines incidence of motion sickness. Motion sickness dose values were calculated from the frequency weighted time history of accelerations, and compared between the vehicles, driving conditions, and the seat positions in the bus. During the driving on public road and high ways for 50 minutes vomiting incidence ratios ranged 0.4 to 0.8%, which were equivalent to 2.4 to 4.8% for 5 hours' driving. The value of 4.8 % means two among 45 passengers may vomit after the traveling, which is very serious situation. Considering the very smooth driving condition at which the data were collected, motion sickness dose values will increase in real situations

The objective of this research is to reconstruct an aristocratic officer's travels by analysing Yu, hee-chun's diary, Miamilgi. Yu had kept his diary for eighty three months, from October 1567 to May 1577, and there were twenty six times of travel logs which are analysed in this research. As a result of the analysis, his travels can be divided into official travels and private travels. Sixteen times of official travels were comprised of inspection tours for parishes as a superintendent of Jeonra province, trips to supervise maintenance works of royal tombs and to worship the tombs, to carry out the sanjae (rituals in the mountains) as a second minister of the ministry of rites. It was difficult for him to have private travels as he continually served as a royal officer. He had got only 10 times of private travels during the eighty three months for maintaining the ancestor's tomb and worshiping the ancestors, for recuperating himself and his wife, and for constructing his new house. All of these travels were long-distance ones. In terms of his travel routes, he frequently used royal main trunks, e.g. 'Haenamro' (from Seoul to Damyang), which were maintained by the royal government. The main reason of his frequent using of trunk lines was that convenience facilities such as the royal post stations (Yeok) and royal inns (Won) were equipped well in these roads so it was easy to get horse change services and lodging and boarding. The fact that main trunks were chiefly straight lines and the shortest way was rather secondary reason. On the other hand, when he was a superintendent of Junra province, he had four times of round inspection on all parishes of Junra province, following the tour routs covering all over the province. As he was incumbent royal officer, he started his travel by getting a permission from the king. Simultaneously, he made ready some travel items. Among the items, horse was most important one for the journey. After finishing all the preparing processes before the departure, he had special farewell ceremony for the King, Sookbae, and had a small party with his friends called Jeonbeul. Main transportation means for his travel was horse, and many kinds of horses such as royal government's horse, Yeokma, local government's horse, Swema, as well as his private one were used. Additionally, he used a palanquin while he was doing inspection trip as a superintendent of Junra province. Yu was incumbent officer so he mostly lodged in local government guest houses. If he could not find out any local guest house, he was lodged in royal inn, and in his relatives houses or irregularly in buddhist temples. Most meals were supplied by local royal governments. The activities in his journeys were varied on his travel objectives. In his private journey, it was the main activities that maintaining ancestor's tombs and having a memorial service. During the trip, he visited his relatives. His official trips, on the other hand, had a regularity. Main activities were dealing with public works, and visiting Hyanggyo (country public school). However in the midway, he visited his relatives and had a journey to scenic places.

아시아-태평양 지역에서의 큰 수요로 1990년대 들어서 종합(global) 관광이 증가하게 되었다. 장거리 여행 또한 보통보다 빠른 속도로 증가하고 있다. 이벤트(행사) 관광은 관광산업계의 격렬한 경쟁에서 아주 강력한 방법으로 등장하였다. 이벤트관광의 경제적 혜택으로서, 대규모의 이벤트는 주체국에서의 관광 지출을 절반정도까지 절감할 수 있으며, 같은 정도로 수입을 증가 시킬 수 있으며, 궁극적으로는 관광객의 지출(expenditure)을 야기시킬 수 있다 (Vantove & Witt, 1987). 이러한 관점에서, '99 하남 환경박람회와 같은 국제적 이벤트가 199년 이후 지방정부의 주최로 한국에서 매년 개최되고 있다. 이벤트의 주요역할은 지역사회의 이미지를 향상시키고, 관광객을 불러들이는 것이며(Holler 등, 1993), 끌어당기는 힘으로써 주최지의 매력을 강조시키는 것이다 (Mill & Morrison, 1985). 한국에서의 이벤트산업은 주최지의 이미지를 흐리게 할 수도 있는 사고에 대한 안전관리의 중요성을 별로 심각하게 인식하고 있는 것 같지가 않다. 조사분석의 결과는 안전시설과 응급시설에 더 만족할수록 재방문의사가 더 크다는 것을 나타내었다. 비록 덜 교육받은 그룹과 학부졸업이상의 그룹 모두 중립보다는 낮지만, 덜 교육받은 방문객은 안전에 더욱 만족한다는 것도 발견되었다. 안전시설의 요소는 재방문의사에 가장 강력한 영향력을 미치는 것으로 나타났다.

It is widely known that the dynamic optimal path algorithm, adopting real-time path finding, can be supporting an optimal route with which users are satisfied economically and accurately. However, this system has to search optimal routes frequently for updating them. The proposed concept of optimizing search area lets it reach heuristic optimal path rapidly and efficiently. Since optimal path should be increased in proportion to an distance between origin and destination, tremendous calculating time and highly efficient computers are required for searching long distance journey. In this paper, as a result of which the concepts of partial solution and representative path are suggested. It was possible to find an optimal route by decreasing a half area in comparison with the previous method. Furthermore, as the size of the searching area is uniform, comparatively low efficient computer is required for long distance trip.

Recently, mobility and accessibility occurs for the elder and the handicapped in the aging problem. In this paper, we analyze the dynamics of slide-up seat, which helps to care the handicapped passenger in and out the automobile when we enjoy trip with the families including the elder and handicapped. We check the trajectories of slide-up seat inside and outside car to protect its corrosion and the stress at the joints of mechanical structure. Those can be helped to keep the safety and accuracy of the multiple dynamic systems for precision quality assurance in mass production.

In the study accelerations at the three Points on the floor of the six test vehicles were measured during the driving at constant speeds.

Motion sickness dose values were calculated from the frequency weighted time history of acceleration signals, and compared between the vehicles, driving conditions. and the seat positions in the bus. During the 50 minutes' driving on the public road and high ways. the vomiting incidence ratios were seen to range from 0.4 to 0.8 ％. which is equivalent to 2.4 to 4.8 ％ for 5 hours' driving. Unlike the very smooth road conditions considered in this work, motion sickness dose values encountered in real situations are expected to increase.
