  • In this study, unwed mothers residing in nine residental facilities were surveyed by questionnaires. Those facilities were selected from national welfare facilities officially registered for single-parent families in 2011. The selected facilities were two places in Seoul, six places in Gyeonggi Province and one place in Chungcheong Province. The surveyed data were analyzed by statistical methods such as frequency, percentage, one way ANOVA, chi-square test and t-test, binary logistic regression using SPSS ver.17.0 program. As a result, their decision of adoption or self-nurture on their child was significantly affected by various factors. Among pregnancy-related factors, pregnancy recognition time was significantly different between two groups. Among personal factors, their age and cognition of parental role were important factors to differentiate two groups. In the analysis related with social resources, the self-nurture group had significantly higher experience and satisfaction on welfare service and lodging & boarding service compared to those of the adoption-choice group.

  • Establishing a public transportation transfer system that can reduce personal automobile use in the CBD and absorb the demand, thereby reducing congestion, is a necessity. However, the current transfer system and facilities are lacking in intermodal connectivity, require long transfer times, have complex flow patterns, and are lacking in information systems and convenience. The design analysis program of this study is to develop a program that executes computations of design analysis of transfer facilities by utilizing the existing design standards for facilities such as facilities for boarding and alighting, elements for convenience, and pedestrian facilities. Developing an analytical tool through which individual or integrated design analysis can be conducted on the design standards of various facilities is an important study for improving the work accuracy and efficiency of designing an actual transfer center.

  • Due to extreme urbanization, ground transportation in the city center is saturated, and problems such as the lack of expansion infrastructure and traffic congestion increase social costs. To solve this problem, a 3D mobility platform, Urban Air Mobility (UAM), has emerged as a new alternative. A vertiport is a physical space that conducts a similar role to an airport terminal. Vertiport consists of take-off and landing facilities (TLOF, Touchdown and Lift-Off area), space for boarding and disembarking from UAM aircraft (gates), taxiways, and passenger terminals. The type of vertiport (structure, number of facilities) and concept of operations are key variables that determine the number of UAM aircraft that can be accommodated per hour. In this study, a capacity calculation method was presented using an optimization technique (Deterministic Integer Linear Programming). The absolute capacity of the vertiport was calculated using an optimization technique, and a sensitivity analysis was also performed.

  • In the case of urban railway facilities, the power supply should be maintained for the safe movement of passengers in communication facilities, disaster prevention facilities and boarding area security because of the confusion when power supply is cut off due to the nature of public transportation. In addition, considering that the number of trains is running on the urban railway line, it is necessary to operate at least 30 minutes for the bus stop and at least 1 hour for the communication and disaster prevention facilities. Therefore, it is essential to supply emergency power source to maintain stable operation of induction lamp and smoke exhaust system because main power is cut off in order to prevent further spread due to fire in case of the history of urban railway section or vehicle fires. Recently, UPS(Uninterruptible Power Supply) function to prevent power outage in emergency, emergency power generation combined with ESS function which saves electricity at nighttime price time, A hybrid power storage system with a UPS function.

  • In most public transportation related master plans, decisions for investment priorities are initially made by facilities with lower installation rates or lower satisfaction (performance) levels. In general, the decisions are made without conducting importance factor analysis. In this study, a combined method of importance-performance analysis (IPA) model for bus users related in travel time is proposed by using Structural Equation Model (SEM). The results of the IPA for Metropolitan users show that the categories need improvement are number of bus stops, number of intersections, headways, waiting times for boarding and traffic signal operations in order. On the other hand, Non-Metropolitan uses show that the categories need improvement are traffic signal operations, waiting times for boarding, headways, bus exclusive lanes and number of intersections that is in reverse order to Metropolitan users.

  • The Korea National Agricultural College (KNAC) was established as a special three academic years(six semesters) course by the Presidential Act in July 1995 and opened on March 20, 1997. According to the Act, the students of KNAC are granted free boarding in dormitory, full support of educational expenses, and, after completion, exception in military service and financial support for farming, which is their obligation to do for a double period of the total school year. With these institutional favors KNAC is hight expected to bring up promising young farm managers in Korea. However, actual competitive young farm managers are brought up by the well organized education with emphasis on learning by doing approach. With the relation to the education this study was performed to review and examine present situation of faculty organization, facilities and equipments, curriculum including field training in home land and oversea's counties. This study found out that there were undesirable aspects such as unbalanced faculty members among the departments, lack of practice farm land and limited budget in field training, which should be improved to achieve the objectives of KNAC.

  • Developed in the study is the analysis of human factors involved in accidents of Korean Construction Projects. The 556 cases are sampled from a survey material 'Serious Accident Cases in the Construction Projects' edited by Korea Industrial Safety Corporation in 1995 through 1997. The analysis of these cases shows that existing classification system is not good for practical applications in real spots since they are difficult for engineers to understand. In this paper, human factors are classified into three groups by extracting the analysis and arrangement of the cases. Futhermore, We'll propose here a new type of accident which is subdivided. If engineers use this type of accident, they will be probably able to analyze efficiently human factors which are involved in accidents and relatied with how it happen. In the case of fall and upset accidents, personal factors seem to be critical when workers are horizontally moving in an unstable manner, and vertically moving without boarding facilities. Futhermore work environmental factors are important when workers release some materials and are performing building and dismantling tasks.

  • In general, transfer in subway stations is defined as transfer between lines and station transfer. In transfer between lines, passengers change from one subway line to another by utilizing horizontal pedestrian facilities such as transfer passages and pedestrian way. Station transfer appears in the situation that subway lines of enter and exit gate terminals differs from those of boarding and alighting trains and passenger trips utilize both vertical pedestrian facilities such as stair and escalator and horizontal facilities. The hypothesis on these two transfers presupposes that all subway lines are operated by either local train or express in subway network. This means that in a transfer case both local and express trains are operated in the same subway line, as a case of Seoul Metro Line 9, has not been studied. This research proposes a methodology of finding the same line transfer in the Seoul metropolitan subway network built based on the smart card network data by suggesting expanded network concept and a model that passengers choose a theirs minimum time routes.
