The construction of a new city--which is pleasantly inhabitable-has been a human dream with the birth of city on this earth. It has become a more ardent passion than ever, since the existing city-system starts exerting ill effects and presenting injurious influence upon the agreeable inhabitation. However, the desire for new-city development, in the modern connotation, is stemmed out of the rapid urbanization, which followed the Industrial Revolution. In the mid-20-th century, nations in the world attained economic growth successfully, in various degrees, through industrialization in their economy. This resulted in the enormous population movement into industrialized city, and this intensified population concentration raised some critical issues such as the deterioration of city environment, the developmental distances between regions, and so on. In order to meet these needs and to readjust these injurious effects, a great deal of nations have adopted the new-city development as a remedy. As a promoting scheme for new-city development, the present study discusses ⅰ) the goal of development strategy, ⅱ) the expansion of housing-land, ⅲ) the reformation of city-life environment, and ⅳ) the institutional support. The goal of development strategy should notice the industrial, the commercial, the business, and the daily-living facility as well on the additionally developed building-site, and these facilities should be able to function systematically with one another through effectual population flow. As to the expansion of housing-land, this study suggests the establishment of development-pole in the collected development capacity with concentrated development strategy-rather than eith diffused development strategy. In addition, the spill-over effect from the development-pole should be taken into consideration at the same time. For the reformation of city-life environment, the completion of educational facility, the installation of commercial-business facility, and their comfortableness and security need to be supplemented in the planning. Finally, the institutional support for new-city development includes the finance for construction fund, the balanced unit-development by civilian investment. the higher priority for housing construction fund, the timely establishment of self-determining institution fro developmental administration, and the assistance by tax-benefit in the promoting scheme for new-city development proposed by this study.
A Study on the Service Load State Behavior of Reinforced Concrete Plate Member
Bhang, Jee-Hwan,Kang, Won-Ho Korea Concrete Institute 2000 KCI concrete journal Vol.12 No.2
This paper proposes a mechanical model to describe the load-deformation responses of the reinforced concrete plate members under service load state. An Analytical method is introduced on the basis of the rotating crack model which considers equilibrium, compatibility conditions, load-strain relationship of cracked member, and constitutive law for materials. The tension stiffening effect in reinforced concrete structures is taken into account by the average tensile stress-strain relationship from the load-strain relationship for the cracked member and the constitutive law for material. The strain compatibility is used to find out the crack direction because the crack direction is an unknown variable in the equilibrium and compatibility conditions. The proposed theory is verified by the numerous experimental data such as the crack direction, moment-steel strain relationship, moment-crack width relationship. The present paper can provide some basis for the provision of the definition of serviceability for plate structures of which reinforcements are deviated from the principal stresses, because the present code defines the serviceability by the deflection, crack control, vibration and fatigue basically for the skeletal members. The proposed theory is applicable to predict the service load state behavior of a variety of reinforced concrete plate structures such as skew slab bridges, the deck of skew girder bridges.
Topical 0.03% Tacrolimus for Treatment of Pemphigus Erythematosus in a Korea Jindo Dog

<P>Topical 0.03% tacrolimus was used for treatment of a Korea Jindo dog diagnosed with pemphigus erythematosus. The dog was slowly improved following application of tacrolimus but did not achieve complete remission until end of this study. No adverse effects on clinical or laboratory parameters were noted during the topical tacrolimus therapy period.</P>
Estimating historic lake stages from one-time snapshot, the Shuttle Radar Topography Mission of 2000
Bhang, Kon Joon,Schwartz, Frank W.,Park, Seok-Soon John Wiley Sons, Ltd. 2010 Hydrological processes Vol.24 No.13
<P>Lake studies play an important role in water management, ecology and other environmental issues. Monitoring lake stages is typically the first step on the lake studies. However, for the Prairie Pothole Region (PPR) of North America with millions of small lakes and potholes, onsite measurements for lake stages are almost impossible with the conventional gage stations due to the limited accessibility to lakes and the requirement of economical and human resources. To overcome this limitation, we employed the remote-sensing approach to extract lake stages in PPR for bulk processing. To estimate lake stages, several image-processing techniques were used with the Shuttle Radar Topography Mission (SRTM) data in January, 2000, a one-time snapshot useful in historic lake level reconstruction. In this research, image processing techniques, for example, averaging, Fast Fourier Transform (FFT), Lee-Sigma filtering were applied and masking with Canny Edge Detector (CED) and semi-automated contouring were developed for lake stage estimation. In terms of simplicity, averaging might be useful if 1·5 m of the local bias for the study area in stage estimates. However, the FFT and Lee-Sigma methods were slightly better than averaging. Masking with CED and semi-automated contouring provided outstanding accuracy in the estimation. The masking and contouring methods provided ± 0·5 m of stage differences for relatively large lakes greater than 10 km<SUP>2</SUP> when compared with stage reading in spite of their calculation complexities and was shown as the best approaches among implemented methods in this study.
