In this paper, we study whether customizing at the self-driving shared vehicle boarding stage can satisfy ownership satisfaction. To this end, a preliminary survey was conducted on the general public on the factors of satisfaction/uncomfortable in the current shared vehicle use along with a prior research survey. Subsequently, we validate the preference for customizing elements and their impact on ownership satisfaction through CVT. Pre-investigation has shown that olfactory and interaction elements give greater satisfaction to ownership satisfaction, and CVT results show that the customizing of boarding elements will enable the satisfaction of ownership satisfaction.

Image always carry useful information, detecting a text from scene images is imperative. The proposed work's purpose is to recognize scene text image, example boarding image kept on highways. Scene text detection on highways boarding's plays a vital role in road safety measures. At initial stage applying preprocessing techniques to the image is to sharpen and improve the features exist in the image. Likely, morphological operator were applied on images to remove the close gaps exists between objects. Here we proposed a two phase algorithm for extracting and recognizing text from scene images. In phase I text from scenery image is extracted by applying various image preprocessing techniques like blurring, erosion, tophat followed by applying thresholding, morphological gradient and by fixing kernel sizes, then canny edge detector is applied to detect the text contained in the scene images. In phase II text from scenery image recognized using MSER (Maximally Stable Extremal Region) and OCR; Proposed work aimed to detect the text contained in the scenery images from popular dataset repositories SVT, ICDAR 2003, MSRA-TD 500; these images were captured at various illumination and angles. Proposed algorithm produces higher accuracy in minimal execution time compared with state-of-the-art methodologies.

The purpose of this study is to examine the changing process of the collective housing in Korea; focusing on the alteration process of the apartment housing, which became a representative housing type in Korea, nowadays. The alteration process of the apartment housing in Korea can be divided into three stages: the introduction stage, the trial stage and the settled stage. The introduction stage is the period between 1920, when the collective-housing buildings were constructed in Korea for the first time, and the Liberation of Korea(1945). The trial stage is the period between 1945 and 1975. During this period, common housing has been constructed. And the massive apartment buildings were started to be supplied after 1975. The settled stage is the period between 1975 and the present. The main scope of this study will be the introduction and trial stages, since a lot of in-depth studies have been executed on the settled stage. The history of the collective housing of Korea starts with City Housing of Seoul, in 1921. It is guessed that this housing was to be small-sized and row-housing type. The first-built, apartment-type building, in Korea, was Mikuni Apartment House, which was constructed as a boarding room of Mikuni Company. In the introduction stage, apartment buildings were built by Japanese architects, with Japanese housing style. Most of them were planned in dormitory type, and some of them were run as tenant houses. Most of them were constructed by bricks, but sometimes by timbers. Tadami was laid in every room and inside-corridor was located in the middle of the house. Although the major style of the apartment buildings was Japanese, the Korean dwellers of those apartments has been influencing the housing type of them. In the trial stage, apartment housing has been experienced in diverse ways. With the development of building technology, floor heating system was settled in apartment housing. This improved the amenities of apartment dwelling remarkably. Although some heterogeneous characteristics still remained in the apartments of Korea, in terms of housing style, the housing style of apartments has been changed into own style of Korea, in accordance with Korean people's life style. The results of this study give us some good implications regarding contemporary housing plan: First, if the unit size of a collective housing is small, the more space could be available for community activities. Second, when planning of collective housing, more concerns should be payed on surroundings. Third, more attention should be payed about low-rise apartment housing, and more land-friendly planning would be required.

The purpose of this study is to minimize physical obstacles, to propose how we can improve them, and to get the basic information to establish the welfare policy for handicapped students in the university dormitory by studying and analyzing actual conditions of existing facilities and its improving transition which provide most important living accommodation to university students. To carry out this study, they have been surveyed 10 Universities in Korea as a case study which 1 university in Seoul & Kyunggi province, 2 universities in Chungchung province, 5 universities in Jeolla province and 2 universities in Kyungsang province. And they have been studied in relation to the law, theory of the architectural planning & design, and general consideration about handicapped people. As a result the checklist about the facilities was made. The term of survey was in August 2001 and in September 2004. It is concluded that most of universities which have been surveyed were equipped with good facilities for general students without regards for handicapped people at that time. As you can see the result of this research, the facilities of boarding house for handicapped people are very scanty in many universities. So they must be required facilities for handicapped people in the stage of architectural programming, the process of designing the dormitory facility.

In case of high-levelled platform in the urban railway system, a certain width of gap is inevitably formed between the train and the platform, and the gap gets wider when it is concerned with curved portion of the tracks at platform. This gap greatly contributes to decrease of passengers' safety while boarding and alighting a train. In particular, it endangers children's safety. Gap filler system is often fitted out to minimize gap and to overcome this safety problem at platform. However, as existing gap fillers are in most case structurally complex and organized to be powered from separate supply unit, there are a range of non-favorable points from the viewpoint of cost, installation and maintenance. In addition, existing gap fillers are due to cause disruptions in operation of train, with failures such as malfunctioning of control system. In this study, the authors will review on the gap filler applicable to the platforms of various height types, which neither requires any modifications of the train nor causes any operational disruptions. The proposed gap filler system here is a by-stage retractile type and based on the idea of interlocking it with train doors open-close mechanism, without any additional power supply unit or control system.

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.

In 4th Industrial Revolution, technologies such as artificial intelligence, Internet of Things, and Big data are closely related to the maritime industry, which led to the birth of autonomous vessels. Due to the technical characteristics of the current vessel, the speed cannot be suddenly lowered, so complex communication such as the help of a tug boat, boarding of a pilot, and control of the vessel at the onshore control center is required to berth at the port. In this study, clustering analysis was used to resolve how to establish control criteria for vessels to enter port when autonomous vessels are operating. K-Means clustering was used to quantitatively stage the arrival pattern based on the accumulated AIS(Automatic Identification System) data of the incoming vessel, and the arrival phase using SOG(Speed over Ground), COG(Course over Ground), and ROT(Rate of Turn) Was divided into six phase.
