Most textbooks of urban geography explain that land value drops down with distance from the Peak Land Value Intersection of urban center. However, There is little rigorous empirical work supporting this belief. Using the publicly notified individual land price data of 2013, this paper examines the structure of land value in urban center with a focus on spatial distribution of land value by land use. As an analytic result, the structure of land price varies between land uses, significantly being different from the classical model of land value in urban space. In residential lands and mixed-use lands for residence and commerce, land price gradient as a function of distance from PLVI is positive and a crater phenomenon even is identified in spatial distribution of land value. The classical model coincides only with land for commerce and office. Nonetheless, predict of land uses by land value function fairly corresponds to Alonso's model.

In order to deal with the increase of container cargo traffic volume more effectively, the ministry of maritime affairs & fisheries has a long-term plan to develop Gaduk Island. According to the plan, the New Port will handle 4,600,00TEUs annually. The completion of the project will enable the port of Busan to perform as a hub port in the Asia Pacific era of the year 2000 with sufficient port facilities, and this will lead to a new era of oceanic Korea. With the advent of the Pacific Rim Era of the year 2000, Busan metropolis has set a strategic development plan to establish the area as the center of logistics in the noreast Asian region as well as to become the stronghold of economic activity in Korea's southeast region. To this end, industries that will open the doors to a marine era and a new industrial complex focused on logistics are planned in the West Busan area where Gimhae International Airport and the Busan New Port meet. This paper aims to find out the functional relation and complement between the Busan New Port Distri-Park handing container cargo traffic volume and the West Busan Logistics Pa가 handling an air cargo and railroad goods.

The objective of this study was to identify the risk factor and protection factor related to suicide ideation in each life course based on an ecological-system perspective. A questionnaire was carried out for 393 adolescents, 473 adults and 376 aged men living nationwide. The results are as follows. First, the suicide ideation was low with 1.78 points in the full mark of 5 points. Second, the difference in suicide ideation, depression, hopelessness, stress in the organic system variables, family solidarity in the micro system variables, intermediate system variables, residence, the existence/inexistence of counselling center and the influence of mass media in mezo system variables in each life course were significant. Third, the relative influence of organic system variables on the suicide ideation were largest in all life courses. Further, the depression and the influence of mass media in all life courses were a risk factor of suicide ideation and stress was also a risk factor of suicide ideation in the case of adolescents and the aged. When examining protection factors of suicide ideation, family solidarity, minute as it is, works as the protection factor of suicide ideation in the case of adolescents. For the adults, living in a metropolis was a protection factor from suicide ideation. For the aged, family solidarity, family history of suicide and adult children's attention to their friends and neighbors (intermediate system variable) were protection factors from suicide ideation. I suggested that policy, service, counseling and educational program proper to each life course were necessary to lower risk factors of suicide ideation and to improve protection factors.

The uniform hazard spectra for seven major cities in Korea, Seoul, Daejeon, Daegu, Busan, Gwangju, Ulsan, and Inchon are suggested. Probabilistic seismic hazard analyses were performed using the attenuation equations derived from seismology research in Korea since 2000 and the seismotectonic models selected by expert assessment. For the estimation of the uniform hazard spectra, the seismic hazard curves for several frequencies and PGAs were calculated by using the spectral attenuation equations. The seismic hazards (annual exceedance probability) calculated for the 7 metropolises ranged from about $1.4305{\times}0^{-4}/yr$ to $1.7523{\times}10^{-4}/yr$ and averaged out at about $1.5902{\times}10^{-4}/yr$ with a log standard deviation of about 0.085 at 0.2 g. The uniform hazard spectra with recurrence intervals of 500, 1000, and 2500 years estimated by using the calculated mean seismic hazard on the frequencies presented peak values at 10.0 Hz, and the log standard deviations of the difference between metropolises ranged from about 0.013 to 0.209. In view of the insignificant difference between the estimated uniform hazard spectra obtained for the considered metropolises, the mean uniform hazard spectrum was estimated. This mean uniform hazard spectrum is expected to be used as input seismic response spectrum for rock sites in Korea.

It is suggested investigating method about the existing state of demand in this study. The total demand of 357 water amenity zones in 2014 is estimated based on the growth curve models. The effects of population density and distances between water amenity zones and metropolises populated over 1 million are investigated on each river system. The suitability like RMSE and MAPE of logistic and gompertz models are considered to select more suitable model for each water amenity zone. Demand for water amenity zones in 2014 is seemed to be rather high at Han Gang river system and Chungcheongbukdo after analyzing. The influence of population density is rarely effective except Geum Gang river system. The influence of metropolis on the demand for water amenity zones is higher at Geum Gang river system than others.

Objectives: This is an explanatory correlational study to assess the level of and the relationship of the related factors of health promotion behavior by gender among college students. Methods: Subjects were 950 of the freshmen of the year 2010 at a university in a city adjacent to a metropolis, in S. Korea. Data were collected from the freshmen who understood the purpose of the study and agreed to participate during a freshmen core course using a structured questionnaire. Related factors include active- and passive-self efficacy, internal health locus of control, and social support. Related factors were compared between male and female using t-test and the relationship between the related factors and the health promotion behavior was analyzed separately for each sex, by multiple regression analysis using SPSS 12.0. Results: There were differences in the related factors of BMI between male and female students. They were alcohol behavior and perceived health status among female students while smoking status, alcohol behavior, perceived health status, and BMI among male students. Result from the multiple regression analysis revealed difference in the related factors and in the magnitude of the relationship evaluated by the standardized beta coefficients. Significant factors, listed by the magnitude of beta coefficients, among female were social support, active self efficacy, passive self efficacy, internal health locus of control, and alcohol behavior. Significant factors among male students were social support, active self efficacy, smoking, internal health locus of control, passive self efficacy, and perceived health status. Conclusions: There are gender difference in health promotion behavior and the related factors. The results suggest that the gender differences need to be considered when planning health promotion programs in college. Further research is necessary in order to draw consensus on roles of the related factors of health promotion behavior.

This study suggests optimal policy options for collection of used diapers through benchmarking of foreign countries and perception surveys. By conducting a survey, this study can identify the actual problems involved in the collection process and enhance the social acceptance toward diaper recycling policies. As a perception survey result, the economic burden of emission bags and sanitary issues were most important for the collection pilot test. Respondents thought that twice-a-week collection frequency was appropriate and that free emission bags might be preferable to participants. Currently municipal wastes are subject to waste management laws, which are applied by local governments. Diaper waste is categorized with municipal waste, so it seems to be treated by municipal waste systems. In terms of connection with government, possible alternatives were suggested to identify the relevant local government. Useful data could be obtained, to determine the economical viability of any future diaper recycling system implementation in the entire Seoul metropolis and adjacent areas of dense population.
