In this paper, we design and implement the Walking Life Festival application, which is based on the Android platform and provides information about domestic travel destinations and regional festivals in South Korea. This application utilizes various sensors found in smartphones, including the Step Counter sensor, Step Detector sensor, Acceleration sensor, and GPS sensor. Additionally, it makes use of Google Map API and Public Open API to offer information about domestic travel destinations and local festivals. The application also incorporates an automatic login feature using the Shared Preference API. When storing login information in the database, it encrypts the input plaintext data using a hash algorithm. For Google Maps integration, it creates objects using the Google.maps.LatLngBounds() method and extends the location information through the extends method. Furthermore, this application contributes to the activation of the domestic tourism industry by notifying users about the timing of local festivals related to domestic travel destinations, thus increasing their opportunities to participate in these festivals.

여행지에서 제공하고 있는 스탬프 투어링 서비스는 여행객들에게 특별한 기념이 되어주고 있지만, 스탬프를 받기 위한 장소를 찾기 어려운 점과 여행지의 주변 정보를 얻기 위해서는 여행자의 별도의 노력이 필요하다는 단점이 있다. 이러한 문제를 해결하기 위해 유명 관광지 및 추천 명소 등에 NFC 태그를 설치하고 간단한 태깅만으로 스탬프를 수집할 수 있는 어플리케이션을 제안한다. 또한 이 어플리케이션에 저장되는 정보와 평가를 이용해 사용자별 맞춤 여행 코스를 제공하고 사용자가 좀 더 편리하고 재미있는 여행을 즐길 수 있도록 돕고자 한다.

This thesis enhanced the degree of utilization of smart phone through carrying out the application/app. which search and visit matjip (reputable restaurant) at the travel sites using smart phones. When we search matjip (reputable restaurant) using materialized application, we can select the best matjip (reputable restaurant) we want. Especially, this application evaluates individual restaurants through the level of utilization and satisfaction by consumer including appropriate menus, the style and design of the restaurant, reasonableness of prices, service of restaurant employees and sanitation management by region and registered the information input to DB in advance while classifying based on the evaluation scores to keep track for individual tastes. And individuals can record their personal memories to input columns. On top of that, information field for transportation is also designed to enhance the accessibility during travel, and in the future the application can be further utilized through the expansion of the DB through the input of famous tour sites and acquaintance's house information.

The purpose of this study is to identify the needs of domestic and overseas tourists in the growing travel industry and platform industry and propose a customized matching platform service. A survey was conducted on a total of 106 people from domestic teenagers to 60s or more and case studies with domestic travel related and expert matching application. According to this survey, It was possible to identify the inconveniences and necessary needs during the trip. As the aging society is on the way, It propose a local guide matching platform service that can cover not only 20s and 30s but also 40s ~ 60s, which will be a competitive platform service in the age of 100 years. However, since this study have studied a somewhat comprehensive age range from 20 to 60 years or older, future studies will require intensive research on subjects aged 40 to 60 years or older.

The estimation of total travel time on highway link for a day or year is the most important process for the feasibility analysis of highway or railway. Most of current guidelines for feasibility studies have been based on the time-traffic volume relationship from the BPR, and the traffic volumes have been determined by the application of the design hour factor to the annual average daily traffic volume. Both of the BPR function and the application of the design hour volume may result in the over-estimation of travel time due to the fact that the traffic volume on the large portion of highway links in Korea are close to the capacities. This study proposed a new way which is based on the distribution of hourly volumes for a year. It could be closer to the real situation, and provide more reasonable estimation. This methodology was validated for the national highways, but may be applicable for any type of highway with the AADT.

Vehicular ad hoc networks (VANETs) have a number of interesting applications to preserve road safety, notify users about changed road/traffic condition, handling post accident hazards and moreover service oriented applications to make the travel convenient to the drivers. Use of common information format for diverse applications enables the application developers to easily design flexible information dissemination system for new applications or add new features to existing application. This paper introduces a common information format for various applications in VANETs. The main goal of the paper is to design generalized distributed architectures for vehicular networks, which considers diverse application development scenarios and uses common information format. The proposed architectures enable the application developers to flexibly disseminate information to affected or interested user. In this paper, we have given a detail description of each component of the architectures and how they communicate with each other. In future, we will implement the proposed architecture using suitable simulator.

The trend is growing domestic and international travelers. Research before making plans to travel people, Leave the tour you do not know the way, there are people who can not find a better destination. In this paper, to solve this problem and provide a mobile-to efficiency in traveling through a smart-phone application. At the same time to improve the convenience and satisfaction, etc. Select the destination country and traveling through the guidance system and the destination in the shortest path from the current location of the user to select multiple destinations shorten the travel route and save time. Also implemented to provide a convenience to guide the position of the additional facilities.

PURPOSES: The purpose of this paper is to estimate expected effects on traffic operational and economic aspects of 2+1 roads application in Korea. METHODS : Micro simulation study using VISSIM 5.0 was used to analyze the operation efficiency of 2+1 roads compared to two-lane highways and four-lane highways. Some scenarios for various traffic volumes were set up in order to analyze the effect of 2+1 roads under various traffic situations. Also imaginary road networks were set up for each type of roads. The MOEs to measure the operation efficiency were selected with average travel speed and delay. For analyzing economic effect of 2+1 roads, construction cost of a specific imaginary 2+1 road was compared to construction cost of a four-lane highway with same conditions. RESULTS: The results of study show that a 2+1 road is more effective with 19 percents higher average travel speed and 39 percents lower average delay than a two-lane highway. In the economic analysis, construction costs to construct a 2+1 road are saved as approximately 26.4~40.7 percents when compared to construction of four-lane highway. CONCLUSIONS: It can be concluded that 2+1 roads can improve the traffic operational level of service for two-lane highways and 2+1 roads can be applied as an effective design alternative for higher-volume two-lane highways in Korea.

This paper describes an expert system of progressive die. Because of the complexity for die structure and of the critical problems for press machine mechanism in the progressive press process such as, the travel length in process, the equalized press load, and the other design parameter, it has been increased the requirement of the CAD system for progressive die design more an more. So, through this study, an expert system of progressive die has been developed. The results from the system developed were suggested the possibility of applications in the practice. To develop this system, it has used c-language under the HP-UNIX system and CIS customer language of the EXCESS CAD/CAM system. An application of this system will provide effective aids to the designer in this field.
