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.

용지경계의 불부합은 공사 현장의 용지 보상 때마다 발생되는 커다란 문제점으로 대두대고 있으며 이로 인한 공사비증액, 재설계, 공사지연등 많은 국가적 예산을 소모하고 있는 실정이다. 이에 금번 연구에서는 "광명시대로 3-15호선 외 2개도로 개설공사"에 대하여 용지 불부합에 대하여 그 원인을 분석 하였다. 그 결과 연속지적도와 지형의 불일치로 인하여 공사용지보상선이 3m-4m 좌측으로 편측되어 있음을 알 수 있었으며 이로 인한 추가 용지보상과 재설계가 불가피 하게 되었다. 향후 연속지적도의 좌표체계의 정확도 개선 및 수정 그리고 지형 지적도의 일치하는 작업이 시급한 것으로 나타났다.

Purpose: The paper aims to: 1) identify the reasons for the low usage of recycled paper in domestic workplaces and the premature state of recycled paper industry; 2) assess the environmental effects of replacing domestically consumed copy papers with recycled papers; and 3) suggest ways in which the recycled paper industry can expand in South Korea. Method: Questionnaire survey with cluster sampling is used to identify the attitudes and behavior with respect to recycled copy paper, the results of which are analyzed using SPSS. The environmental effect of replacing copy papers with recycled paper is assessed through the Life Cycle Assessment approach and Paper Calculator V4.0. Result: While the respondent's experience in using recycled copy paper was relatively low, they tend to acknowledge the need for its use and show relatively high satisfaction with the quality of the recycled paper. The environmental benefits of replacing ordinary copy paper with 40%+ recycled paper under the 10% market share increase scenario amounts to 60,000 tons of CO₂ emissions reductions. Conclusion: The results from the attitude survey and market research, five approaches to improving the recycled copy paper market are suggested.

Purpose: The aim of this study was to develop a dry eye test method using a paper based microfluidic device that improves inaccuracy caused by using one of current point-of-care dry eye tests such as Shirmer's. Methods: Wax printed hydrophilic chromatography papers were dyed with anthocyanin extracts to detect colorimetric display of liquid samples with varying pH. Fluid distribution rates were measured using artificial tears and human tears directly from 32 subjects. Results: With Shirmer's, fluid distribution rates with small amount of samples (less than $0.5{\mu}l$) were not displayed. However, with paper based microfluidic device, fluid imbibition distances over time were clearly showed. Also clinical results of dry eye from newly developed paper based microfluidic device showed correlation with the results from tear break up time tests. Conclusions: The newly developed paper based microfluidic devices were easy to use and exhibited more accurate clinical results than current dry eye point of care tests such as Shirmer's.

This paper deals with historical changes in the market of Korean newsprint paper since 1945. Particularly, this paper does not examine only the structure of supply and demand in the newsprint paper market, but also general dynamics of the market from a perspective of Harold Innis's socioeconomic history. As a result, this paper concludes that the general dynamics of Korean newsprint paper market has persistently responded to a stimulus from external markets due to a scarcity of natural resources. To more concretely put it, until 1967 when the newsprint paper market was opened, Korean government had tried to control both newspaper industries and paper manufacture businesses by the matters of price and distribution of the newsprint paper. But since the market was opened, a general dynamics of the Korean newsprint paper market has been vulnerable to uncoordinated properties of external markets. Consequently, even though 'self-sufficiency' of newsprint papers was achieved in 1974, the price of newsprint papers has been often rising and falling.

This study purposed to extract and assess the accuracy of assessment for deforestation area in Wonju city using medium resolution satellite image. The total size of deforestation area during the last nine years (2000-2008) was about 467 ha, and it was occurred annually about 52 ha. The most frequent form of deforestation was settlements (72%). Ninety percent of the size of deforestation was less than 2 ha in size. In addition, 79 percent of deforestation area was found within 500 m from the road network and within 100 m of the Forest/Non-forest boundary. This study compared the deforestation based on the administrative information (GIS deforestationI) with the deforestation (RS deforestation) extracted from the satellite imagery by vegetation indices (NDVI, NBR, NDWI). Extraction accuracy, mean-standard deviation${\times}1.5$ applied 3 by 3 filtering, showed reliable accuracy 35.47% k-value 0.20. However, error could be occurred because of the difference of land-use change and land-cover change. The actual rate of land-cover change deforestation area was 32% on administrative information. The 7.52% of forest management activities area was misjudged as deforestation by RS deforestation. Finally, the comparison of land-cover change deforestation (GIS deforestationII) with the RS deforestation accuracy, as a result NDVI mean-standard deviation${\times}2$ applied 3 by 3 filtering, showed improved accuracy 61.23%, k-value 0.23.
