In recent years there have been studies on tour based approaches for freight travel demand modelling. The purpose of this paper is to analyze tour type choice behavior of commercial vehicles which are divided into round trips and chained tours. The methods of the study are based on the decision tree and the logit model. The results indicates that the explanation variables for classifying tour types of commercial vehicles are loading factor, average goods quantity, and total goods quantity. The results of the decision tree method are similar to those of logit model. In addition, the explanation variables for tour type classification of small trucks are not different from those for medium trucks', implying that the most important factor on the vehicle tour planning is how to load goods such as shipment size and total quantity.

본 논문에서는 복잡 배경을 포함한 비디오 영상에서 객체 변형 및 겹침에 강건한 칸투어 추적 방법을 제안한다. 복잡 배경에서의 칸투어 추출 문제를 해결하기 위해 텍스처 분석과 노이즈 필터링 과정을 거치며, 보다 객체 원형에 가까운 칸투어 추출을 위해 각 칸투어 포인터 간 최소 경로 측정 알고리즘을 적용한다. 객체 추적 방법에 있어서 추출된 칸투어 정보는 연속된 프레임 상에서 객체 움직임이 발생했을 때 추적 위치를 판별하기 위한 모션 벡터로 사용되며, 시점에 따라 형태가 변하는 상황을 포함한 팬, 틸트, 줌에도 안정적 추적이 가능하게 하기 위해, 폐곡선을 이루는 각 칸투어 포인터들의 움직임 벡터와 칸투어내 면적의 변화에서 측정되는 이동도 측정을 통하여 객체 위치 추적을 가능하게 하였다. 또한 매 추적 과정을 진행함에 있어서 다른 객체의 겹침 및 모양변형 발생여부 검사과정을 통하여, 안정적인 추적이 가능하게 하였다. 본 논문에서 제안한 방법의 성능을 검증하기 위해 다양한 배경을 갖는 복잡 배경에 존재하는 비정형 객체를 대상으로 실험하였고, 제안된 방법이 효율적임을 확인할 수 있었다.

This paper contains the design and implementation results of a package tour management application using a Geofence technology as well as the performance evaluation. This application ables the tour guide to monitor the tourist movement in real-time whether the tourists are inside the virtual polygonal Geofence set by the tour guide. Even when the tour is moving between travel destinations, a virtual circular Geofence can be set by the tour guide to monitoring the tourist movement while on the move. The application includes tour guide's and tourist's locations, schedule and participant management. To evaluate the performance, average response time and accuracy is measured, resulting in satisfactory performance. The average response time ranged from 0.0047 seconds to 7.3 seconds in various cases and for accuracy, it scored 100% in various cases. It is expected that implementing Geofence technology to package tour management applications will help tour guides to perform more productive package tours by reducing the burden of managing tourists.

투어멀린는 $XY_3Z_6(Si_6O_{18})(BO_3)_3$ 화학 방정식을 가진 광물로써 조성에 따라 alkali 투어멀린, calcic 투어멀린, X-site vacant 투어멀린 등으로 불린다. 투어멀린 특성과 화학성분에 따라 종을 구분하는데, 주된 종들은 엘바이트, 리디코타이트, 드라바이트, 우바이트, 숄이 있다. 일반적으로 적색 투어멀린의 발색 원인은 Mn, Fe 그리고 Cu의 함량에 따라 색상의 차이를 나타낸다. 본 연구에서 우리는 10MeV 에너지와 $1{\times}10^{17}cm^2$ 조건에서 전자빔을 수행 한 후 투어멀린의 컬러 변화를 관찰하였다. 자외선-가시광선 분광분석결과 모든 시료는 전자빔 조사 후 530 nm의 $Mn^{3+}$부근의 흡수 peak들이 증가하는 것이 관찰되었다. 이는 $Mn^{2+}$에서 $Mn^{3+}$ 이동 때문이여, $Mn^{3+}$는 Y-site에서 O(1)H-O(3)H 축에 따라 Jann-taller 변형으로 안정된 구조를 가지게 된다. 따라서 전자빔 조사 후 적색으로 변하게 되는 것이다. 또한 전자빔 조사 후 컬러가 모두 변했지만 상온에 뒀을 때 변화 된 컬러가 원래의 색으로 되돌아가는 향상을 보였다. 이는 전자빔 조사 후 전자가 튕겨져 나가서 불안정한 상태로 존재하고 있다가 상온의 열에 의한 에너지에 통해 다시 안정된 상태로 되돌아오는 결과로 볼 수 있다. 또한 우리는 WD-XRF를 통해 미량의 Mn 원소함량 차이에 따라 전자빔 조사 시 컬러 변화에 미치는 영향에 대해 확인할 수 있었다. 그리고 적외선 분광분석에서는 4,300-4,600 $cm^{-1}$사이에 특징적인 밴드들이 관찰되었다.

NC 공작기계의 운동정밀도는 키네마틱 트랜스듀서 링크 컨투어 측정시스템(Kinematic transducer link contour measuring system), BDD 측정시스템, Circular Test 등에 의해 측정될 수 있으며, 오차 발생원인을 규명할 수 있다. 이 글에서는 NC 공작기계의 오차가 컨투어 시험 결과에 미치는 영향을 평가하기 위하여, 공칭원(nominal circle) 혹은 공칭호(nominal arc)로부 터의 반경방향 편위를 포함하는 컨투어 운동결과를 이론적으로 해석하였다.

Geotourism is an essential sector of geopark, as it stimulates sustainable development, local socioeconomic development as well as educational effects, from which geo-scientific knowledge can be communicated between the local people and the public. It is also a rapidly growing paradigm of nature-based tourism and is attractive in terms of its year-round accessibility to the sites. Passing over a decade history, it is necessary to present how it can establish a platform for further development and improvement across the country. In this regard, this study is to demonstrate how to develop geotourism model that is effectively applicable to Korean environment based on the enhancement of geotourism. We apply the general geotourism organization model to Haegeumgang in Geojedo Island in this study. Although this area is well known for its small boat tours, privately-guided-tour on the boat is insufficient in terms of delivering geological and geographical information from the geotourism perspective. Therefore, in order to develop the desirable Korean geotourism model, boat tours at Haegeumgang have to be supported professionally by the local government through the geotourism department and the partnership with the stakeholders.

This paper is based on the information left on SNS by the experienced tourist and, First, the tourist gathers various tourist information from SNS through Smart Tourism as suggested, Second, providing scheduling information for future tourist and the future tourist can modify and apply the information from experienced tourist. Third, the goal of this study is to design virtual tourism service based on above services where future tourist can post and modify tourism scheduling. Therefore, it is to obtain the effect of providing reliable tourism service to maximize the satisfaction of the tour through matching process between experience experiences and experience schedule.

Tour is cultural method that makes educational effects smoothly, metaphorically. In a context, dark tour have a function that sustains memorial of accidents and with social meaning, ethic value. This study aims to understand practical solutions of Sewol-Ho memorial on focusing Dark Tourism. This paper considers fascination with this subject and examines explored for good decision. It means that we examines a construction of tour contents within the dark tourism. This article evaluates an dark tourism in a contents program various country, for considering in a case at a Sewol-Ho accident. As a result, we comment some variety choice of strategy effectiveness for a sustainability of ethic value and education memorial.

City tour service has a function not only informs tourists of historical and cultural resources in the city but also contributes to improving city image making. In this study, a questionnaire was surveyed to tourists who used Suwon city tour to find out which factors make affect their intention to re-visit or recommendation to others. Structural equation model was constructed and set a hypothesis that overall city tour satisfaction would have a positive effect. The fitness of the final model was found out to be meet the statistical criteria. As a result of the final model, both satisfaction of guide and satisfaction of city tour operation were significant at 5% significance level (P<0.01). On the other hand, both satisfaction of bus facility and of promotion, customer service were statistically insignificant. Consequently, City tour service satisfaction was found to effect to the intention of re-visit and recommendation. Especially, The higher the satisfaction of guide and city tour operation, the more tendency to recommend. It is expected that local government which operates city tour bus could take advantage of this result in the future.
