This study conducted a survey with 300 male respondents in their 20s to 50s, in order to examine the influence of personal variables, identity of gender roles, self-esteem and social-cultural attitude towards appearance on metro-sexual consumption. The findings are as follows: First, the majority of respondents experienced metro-sexual consumption in passive ways, such as purchasing cosmetics or perfume. Second, self-esteem differed by classification of identity of gender roles and the self-esteem was the most highly rated in non-classified, followed by in femininity, masculinity and androgyny. On the other hand, the non-classified group appeared to have the most highly social and cultural attitude toward appearance. Lastly, when examining the effect of personal variables, identity of gender roles, self- esteem and social-cultural attitude toward appearance on metro-sexual consumption, the results showed that the younger respondents who spend the highest monthly expenses on appearance, belong to the androgynous group and have the social-cultural attitude, are more likely to have a greater tendency towards metro-sexual consumption.

With 34 years of accumulated operating experience, Seoul Metro has launched a project aimed at exporting second-hand trains(used EMU cars) to Vietnam while seeking measures for diversifying its business such as the construction of the metropolitan railways both at home and abroad, and operating business as a way of fiscal consolidation and management improvement. Therefore, Seoul Metro has moved ahead with this plan considering that there's no legal constraints on durable period of rolling stocks in advanced countries where the vehicles have been used for 35 years or longer than 40 years through renovation such as safety inspection and comprehensive maintenance program, and the railway systems for the replacement are expected to reach 838 cars by 2015 with growth of 100 cars a year. Seoul Metro strives to create value for boosting revenues and recycling resources by sending used EMUs to Vietnam. Seoul Metro will also provide under-developed countries with cars at a low price as well as share the accumulated railway technical know-how so that it can promote the national image and obtain the pre-emptive effect of metro railways in Vietnam.

Detour of metro (subway) in metropolitan area has been regarded as one of inherent elements that make entire metro system less competitive than passenger cars. However, factors affecting detour of metro line is not specified clearly when a new subway system is planned or an existing system is improved. Previous detour-related studies was reviewed for developing 'distance efficeincy evaluation model' for metro as well as its counterpart (i.e. road). Metro line 3 (orange line) of Seoul metropolitan area was applied as a case study. As a results, the most detoured OD segment is Daechi - Apgujeong and its detour factor is 1.93 which means that the distance of the metro is 1.93 times longer distance compared to the distance of the road. The metro line 3 has averagely 20% longer distance compared to road for the identical O/D pairs.

The ridership and transit systems are influenced by the expansion of metro-rail in Seoul metropolitan area. However, it has been difficult to measure its precise quantitative influences. Also effective policy implementations have been limited due to the lack of practical evidences. Thus an empirical analysis for an operating metro-rail is essentially required. In this regard, this study examines the impact of the Jungang line on transportation system, whose metro-rail block has been recently started new service. The main interest of this study is to find out the changes of ridership and to forecast the ridership changes by the metro-rail service. The results indicate that the effect on auto users is less than that of bus users. The auto demand is decreased by 33.3% and the bus demand by 66.6%. Additionally, its influence on Gyeonggi-do bus was greater compared with that on the Seoul bus. From questionnaire survey, this results could be confirmed. To sum up, the metro-rail gives less influences on auto users, while it gives greater influences on bus users.

Current metro tickets are categorized into transportation cards and monthly season tickets, which offer limited consumer choices. A metro fare system should be introduced based on the diversity of customer demand. Thus, this study's objective is that the metro fare system in Korea should be efficiently operated by analyzing a variety of metro fare systems used in major cities of other countries. In addition, this study proposed the following metro fare systems, one day pass, which is generally used in other countries in a bid to promote public transportation, reduce costs, and increase revenue. A commuting ticket system to increase the demand from cars to subways, and special discounts & a round-trip ticket system for round-trip travelers in case that demand is low was compared with the high supply on the Gyeongchun-line.

One of the most common forms of land use change is urbanization. Fortunately, the temporal revisit capacity of remote sensing satellites and their multispectral imaging capability make it possible to monitor this process. Using two Landsat images taken in 1972 and 1989, and one SPOT image taken in 2000, urban growth in Metro Manila is monitored. The extent of urbanization in Metro Manila increased from about 39 percent in 1972 to about 74 percent in 2000, although a slowing of growth was observed in the last decade due to decreasing areas for development. Most cities and municipalities in Metro Manila exhibited urban growth rates higher than the metropolitan average. The drivers and environmental consequences of urban growth were determined as well as the relationship of the extent of urbanization with some socio-economic and environmental variables.
