우리나라 선원은 해방기 이후 외화가득의 주역이며 비상시 군수물자를 운송할 수 있는 사회경제적으로 가치 있는 직업이나 최근 선원 직업의 사회적 인식이 다소 부정적이고, 예전처럼 젊은 선원의 유입이 높지 않은 편이다. 본 연구는 일반 대중을 대상으로 Q 방법론을 활용하여 선원의 직업을 어떻게 인식하는지 그 이미지 유형과 특성을 분석하였다. Q 방법론에 의한 선원 직업 이미지 인식은 3개 유형으로 분류되었고 우리나라 선원에 대한 대중의 인식은 부정적이였다. 이러한 연구 결과를 바탕으로 해운산업의 핵심 인적자원인 선원의 안정적으로 확보하고 선원 종사자들의 직업적 만족도와 취업률을 높이기 위해서는 대중들이 인식한 선원의 부정적 직업 이미지를 전환할 수 있는 다양한 방안을 마련해야 할 것이다.

The Korea metropolitan areas have the largest of population density in OECD countries. Those people who use public transportation is facing many difficulties in commuting and going to school. There are many applications to help this situation. However, those applications inform a regular timetable and also offer a real-time alarm to user by user's passive action. In this paper, we design and implement the application that give the real-time traffic information and the arrival notification message about subway, bus and foot to user.

Recognition for the importance and roles of public transportation is increasing because of traffic problems in many cities. In spite of this paradigm change, previous researches related with public transportation trip assignment have limits in some aspects. Especially, in case of multimodal public transportation networks, many characters should be considered such as transfers. operational time schedules, waiting time and travel cost. After metropolitan integrated transfer discount system was carried out, transfer trips are increasing among traffic modes and this takes the variation of users' route choices. Moreover, the advent of high-technology public transportation card called smart card, public transportation users' travel information can be recorded automatically and this gives many researchers new analytical methodology for multimodal public transportation networks. In this paper, it is suggested that the methodology for establishment of brand new multimodal public transportation networks based on computer programming methods using transportation card data. First, we propose the building method of integrated transportation networks based on bus and urban railroad stations in order to make full use of travel information from transportation card data. Second, it is offered how to connect the broken transfer links by computer-based programming techniques. This is very helpful to solve the transfer problems that existing transportation networks have. Lastly, we give the methodology for users' paths finding and network establishment among multi-modes in multimodal public transportation networks. By using proposed methodology in this research, it becomes easy to build multimodal public transportation networks with existing bus and urban railroad station coordinates. Also, without extra works including transfer links connection, it is possible to make large-scaled multimodal public transportation networks. In the end, this study can contribute to solve users' paths finding problem among multi-modes which is regarded as an unsolved issue in existing transportation networks.

Previous studies on the transit assignment hardly show its achievement in research but have many limitations not only in theory but also in practice. This paper presents an integrated transit assignment model taking into account cost functions of multiple modes, such as auto, bus and subway, which represent an integrated network. An integrated transit network including cost functions and in-vehicle congestion needs to be developed. In addition, a link fare calculation model needs to be developed and applied to the model to calculate path travel costs. Based on these sub-models, a path-based traffic assignment model, which considers in-vehicle congestion and an integrated distance-based fare system in the integrated traffic network, is developed.

The purpose of this paper is to analyze the blind spot for public transportation by level of service(LOS) in public transportation supply service. For the purpose, we proposed indices of service coverage area, service frequency and hours of service and analysis method for them. Service coverage area analysis is to decide station location and network design for the maximum beneficiary area. Moreover, we can use the service frequency is for the maximum service frequency decision and hours of service is for the minimum operation hours. The results of this study are applied to the plan of minimum supply service, minimum service frequency and minimum operation hours for city and national public transportation plan.

Restructuring urban land use patterns from the motor-oriented to transit-oriented ones is a contemporary trend in urban planning and transportation. It is expected that transforming urban land use patterns to be transit and walking friendly would resolve various urban problems such as heavy energy consumptions, air pollutions, and traffic congestions. Korean cities have much potentials for developing transit-oriented urban environments in terms of its density and civil service levels, but the level of transit usage levels and the environmental quality of cities are not good enough for supporting such transition. The purpose of this study is to analyze the urban transit center areas and identify the problems to be solved to create transit-oriented urban environments. Case studies of four urban transit center areas in Seoul Metropolitan region were conducted to examine the spatial characteristics of urban transit center areas and identify their problems. Development density, land use diversity, walk-ability and transit connectivity were the primary feature of interests.

'아방가르드'를 세기말에 다시 살펴보는 것은 20세기 문화의 진원지였던 아방가르드가 아직도 '끝나지 않은' 미완의 운동으로 다시 떠오르기 때문이다. 예술과 대중의 관계 등 아방가르드 담론의 핵심은 예술이 사활의 기로에 처한 듯한 오늘날 더욱 외면할 수 없는 문제임이 분명하다.

The smart card data stores the transit usage records of individual passengers. By using this, it is possible to analyze the traffic demand by station and time. However, since the purpose of the trip is not recorded in the smart card data, the demand for each purpose such as commuting, school, and leisure is estimated based on the survey data. Since survey data includes only some samples, it is difficult to predict public transport demand for each purpose close to the complete enumeration survey. In this study, we estimates the purposes of trip for individual passengers using the smart card data corresponding to the complete enumeration survey of public transportation. We estimated trip purposes such as commute, school(university) considering frequency of O-D, duration, and departure time of a passenger. Based on this, the passengers are classified as workers and university students. In order to verify our methodology, we compared the estimation results of our study with the patterns of the survey data.

This study assesses the necessity of popular music instructor training, and promotes the establishment of popular music educational institutions and certification related to applied music education. Popular music has profound influence in popular culture, and is gradually diversifying. However, successful singers predominantly remain mostly boy/girl performance groups lacking musical skills. This study posits the cause of this problem is the absence of popular music instructor training systems, and suggests solutions. Currently, Korea's popular music lacks a public education system that teaches students effectively. Also, popular music is acknowledged as field-oriented, and isn't recognized for its academic value. Lastly, the lack of professional instructor training system in higher educational institutions creates challenges in fostering effective teachers. Solutions to these problems include establishing dedicated educational institutions and establishing certification programs. Implementing these solutions will provide significant positive effects in developing globalization for the currently stagnant K-pop industry. In addition, these solutions would contribute to the stabilization of the popular music industry, enhancing the image, and developing the popular music industry in general. In conclusion, this study promotes the popular music industry development by influencing and promoting awareness of music professionals, not just applied music students.
