Purpose - The purpose of this study was to examine the variations in emotions during vacation and to explore if such variations depend on psychological distance perceived by vacationers. We proposed that there are changes in affect balance during the course of vacation as well as the mental construal of psychological distance. Research Design, Data, and Methodology - Repeated measures ANOVA was used to examine the variation in emotion and psychological distance of 66 holiday makers who were traveling to different destination for vacation. Data were collected in 2 months with the help of a travel agency. Results - We find that there are variations in emotions during the vacation at different points in time as well as perceived psychological distance. Also we find some evidence that suggests emotional happiness does depend on perceived mental distance to some extent. Conclusion - Our study replicates the findings of previous studies in a novel way and illustrates the robustness of the nature of emotions during vacation and indicates certain time points where the happiness of vacationers can be enhanced. Perceived psychological distance do have an effect on how happy an individual feels during the vacation.

매년 여행을 즐기는 여행객들의 수가 꾸준히 증가하고 있으며, 이러한 추세는 해외여행 뿐 아니라 국내 여행에서도 나타나고 있다. 국내 여행을 즐기는 여행객 수의 증가는 매우 다양하고 복합적인 요인들에 의해 이루어지고 있는 것이 사실이나, 국내 여행객들의 절대 다수는 해외여행과는 달리 패키지 형태 보다는 자유여행 형태의 여행을 선호하고 있다. 이는 해외 여행지 대비 국내 여행지가 여행객들이 취득 및 분석할 수 있는 정보의 접근성이 훨씬 높고 정보의 양 역시 풍부하다는 것에서 기인한다고 할 수 있다. 그러나 이러한 정보 접근의 용이성 및 정보량의 풍요성은 오히려 자유여행을 즐기고자 하는 여행객들이 여행코스 및 숙소를 정하는데 많은 시간을 투자하게 되는 요인으로 작용하고 있다. 때문에 이러한 단점을 해결하고자 본 논문에서 제안하는 애플리케이션은 국내 여행객들이 편리하고 손쉽게 국내 여행을 즐길 수 있도록 여행코스 및 숙소를 지정할 수 있는 기능을 제공한다. 이를 위해, 제안하는 애플리케이션에서는 국내 여행과 관련된 다양한 정보들을 각종 포털 사이트와 SNS에서 수집하고, 이를 기반으로 사용자 선호 정보와의 매칭을 통해 맞춤형 여행 코스 제안 및 숙소 예약 기능을 제공한다. 이를 통해, 국내 여행을 즐기는 여행객들에게 편리함을 제공하고, 국내 여행객 수의 증가를 기대할 수 있다.

A complicated case of echinococcosis with multiple organ involvement is reported in a 53-year-old businessman who frequently traveled overseas, including China, Russia, and Kazakhstan from 2001 to 2007. The patient was first diagnosed with a large liver cyst during a screening abdomen ultrasonography in 2011, but he did not follow up on the lesion afterwards. Six years later, dizziness, dysarthria, and cough developed, and cystic lesions were found in the brain, liver and lungs. The clinical course was complicated when the patient went through multiple surgeries and inadequate treatment with a short duration of albendazole without a definite diagnosis. The patient visited our hospital for the first time in August 2018 due to worsening symptoms; he was finally diagnosed with echinococcosis using imaging and serologic criteria. He is now on prolonged albendazole treatment (400 mg twice a day) with gradual clinical and radiological improvement. A high index of suspicion is warranted to early diagnose echinococcosis in a patient with a travel history to endemic areas of echinococcosis.

The increased use of smartphones has made it easier to plan travel. Especially for people travelling in Europe, it is common to move between cities by train, and reserving passes with a mobile app offers many advantages. The Czech Republic, which is a familiar destination for Koreans, is called the "heart of Europe" and it is in central Europe, so it is inevitable to use the railway when travelling. This study has been compared with the structural characteristics of the railway reservation service operated by the Czech and Korean railways. In general, when evaluating the usability of an app, we often use a method that allows a group of users or experts to spot problems. However, this study suggests an analytical method to obtain more reliable and objective results. Also, the analysis of the structural characteristics has an advantage that the problem can be predicted at the prototype stage. This, of course, comes with time and financial benefits. The purpose of this research is to contribute to the development of applications that are more convenient to use and efficiency of development.

Simian malaria is a zoonotic disease caused by Plasmodium knowlesi infection. The common natural reservoir of the parasite is the macaque monkey and the vector is the Anopheles mosquito. Human cases of P. knowlesi infection has been reported in all South East Asian countries in the last decade, and it is currently the most common type of malaria seen in Malaysia and Brunei. Between 2007-2017, 73 cases of P. knowlesi infection were notified and confirmed to the Ministry of Health in Brunei. Of these, 15 cases (21%) were documented as work-related, and 28 other cases (38%) were classified as probably related to work (due to incomplete history). The occupations of those with probable and confirmed work related infections were border patrol officers, Armed Forces and security personnel, Department of Forestry officers, boatmen and researchers. The remaining cases classified as most likely not related to work were possibly acquired via peri-domestic transmission. The risk of this zoonotic infection extends to tourists and overseas visitors who have to travel to the jungle in the course of their work. It can be minimised with the recommended use of prophylaxis for those going on duty into the jungles, application of mosquito/insect repellants, and use of repellant impregnated uniforms and bed nets in jungle camp sites.

Objective: The purpose of this study was to develop and evaluate high technology adaptive driving controls, such as mini steering wheel-lever system and joystick system, for the people with physical disabilities in the driving simulator. Background: The drivers with severe physical disabilities have problems in operation of the motor vehicle because of reduced muscle strength and limited range of motion. Therefore, if the remote control system with driver-by-wire technology is used for adaptive driving controls for people with physical limitations, the disabled people can improve their quality of life by driving a motor vehicle. Method: We developed the remotely controlled driving simulator with drive-by-wire technology, e.g., mini steering wheel-lever system and joystick system, in order to evaluate driving performance in a safe environment for people with severe physical disabilities. STISim Drive 3 software was used for driving test and the customized Labview program was used in order to control the servomotors and the adaptive driving devices. Thirty subjects participated in the study to evaluate driving performance associated with three different driving controls: conventional driving control, mini steering wheel-lever controls and joystick controls. We analyzed the driving performance in three different courses: straight lane course for acceleration and braking performance, a curved course for steering performance, and intersections for coupled performance. Results: The mini steering wheel-lever system and joystick system developed in this study showed no significant statistical difference (p>0.05) compared to the conventional driving system in the acceleration performance (specified speed travel time, average speed when passing on the right), steering performance (lane departure at the slow curved road, high-speed curved road and the intersection), and braking performance (brake reaction time). However, conventional driving system showed significant statistical difference (p<0.05) compared to the mini steering wheel-lever system or joystick system in the heading angle of the vehicle at the completion point of intersection and the passing speed of the vehicle at left turning. Characteristics of the subjects were found to give a significant effect (p<0.05) on the driving performance, except for the braking reaction time (p>0.05). The subjects with physical disabilities showed a tendency of relatively slow acceleration (p<0.05) at the straight lane course and intersection. The steering performance and braking performance were confirmed that there was no statistically significant difference (p>0.05) according to the characteristics of the subjects. Conclusion: The driving performance with mini steering wheel-lever system and joystick control system showed no significant statistical difference compared to conventional system in the driving simulator. Application: This study can be used to design primary controls with driver-by-wire technology for adaptive vehicle and to improve their community mobility for people with severe physical disabilities.

With the COVID-19 pandemic, the global economy has stagnated and our daily lives have changed. The rural economy is also experiencing damage, such as an average of 65% or more decrease in the number of visitors to rural experience resort villages due to the spread of COVID-19. In order to minimize the damage arising from the prolonged coronavirus, a hospitality system in response to changes in rural tourism behavior and consumer demand is needed to revitalize rural areas and maintain continuous economic independence. Therefore, this study attempted to find ways to utilize landscape resources such as education, culture, history, and ecology in order to complement the existing experience programs in connection with local resources and local environment. Wibong Village, which is the subject of the study, attempted to revitalize the village using the resources through the "Creative village creation" project in 2015. Due to poor management of historical resources, difficulty in operating experience programs, and response to changes in the natural environment, the rate of implementation of the project plan was very low. Currently, the demand for experience is also decreasing due to the COVID-19 effect, so it was judged that it was necessary to develop an experience village program suitable for the needs of experienced visitors by discovering additional local resources for the continuous operation of the experience village. In order to solve the problem of the use of landscape resources and the spatial composition of the study site, additional investigations of local resources were made, and an experience program course that could be operated by theme was proposed by configuring a space suitable for the use of landscape resources. By dividing the additionally investigated landscape resources into history, ecology, and region, an experiential course was created to separate the traffic lines, and the space composition for large-scale experienced visitors that had been previously operated was constructed in a form suitable for the post-corona era. In addition, at least two experiential tour courses that can be operated by period were proposed to maintain economic effects. Starting with this study, if further research on the creation and spatial composition of a rural experience village centered on the connection with the region, it will be used as research results that can be referenced in projects such as village creation, rural space planning, and living area analysis. It is expected that it will be able to effectively cope with the construction of a rural area suitable for the post-corona era, where demand is expected to increase in the future.

Purpose: Lymphedema of the scrotum and penis is a functionally and emotionally incapacitating problem for patients. Patients suffer pain from swelling, chronic irritation, repeated infections, drainage, and sexual dysfunction. Although there are various methods for the treatment of scrotal and penial lymphedema, achieving a satisfactory reconstruction in severe cases still remains a challenge due to the lack of locally available tissue. Methods: A 33-year-old man sustained severe lymphedema of the scrotum and penis. He reported a history of swelling since 25 years, which had been intensified during the past few months. There was no history of irritation, surgery, trauma, infection or travel to endemic countries. The authors reconstructed the scrotum and penis using 4 scrotal flaps made by incising the enlarged scrotum crucially. Results: The postoperative course was uneventful. Histopathologic examination showed nonspecific chronic inflammation. The patient was followed up for 18 months and a good reconstructive result was obtained with no recurrence. Conclusion: The authors' method is safe and easy to perform. This method may be a convenient and reliable alternative for the treatment of severe lymphedema of the scrotum and penis.

Dengue fever is an important health problem for international travelers to all endemic areas. The steadily increasing numbers of tourists visiting endemic areas raise the risk of exposure, and imported dengue cases are increasingly observed in nonendemic area. Dengue has a wide spectrum of clinical presentations, often with unpredictable clinical evolution and outcome. While most patients recover following a self-limiting, non-severe clinical course, a small proportion progress to severe disease such as dengue hemorrhagic fever or dengue shock syndrome. Therefore, it is important to suspect dengue fever in every febrile patient returning from the tropics. Whenever it is suspected, a quick diagnosis and adequate managements are essential to avoid complications. We report two cases of imported dengue fever in Korean children presenting with fever, headache, nausea, and rash.

Now RC cars have become a culture where everyone who wants to feel precise control and rushing instinct regardless of sex, young or old can participate. In addition, RC cars have attracted a lot of people because they can feel the feeling of driving while driving a car in a small, lightweight body. In line with these trends, various development companies are focusing on functional aspects such as driving and speed improvement for each environment and their sophistication. Of course, driving performance alone can bring a tremendous ripple effect, but what you can do with a RC car is only part replacement and motor modification. Therefore, we will develop RC car based on raspberry pie, control by application, add various functions through sensor recognition, and develop RC car that can travel through video information that can be obtained using web cam. As a small RC car, we carry out research that can combine the functions that can be used as a robot that moves at various construction sites and accident sites where people can not enter, and which can attract users' interest.
