While the zoning system has been developed based on the rationale of separated and specialized land uses to prevent negative externalities in the modern industrial era, the emergence of office-based new industries in the post-industrial era rather encourages mixed land uses to create agglomeration economies. This study aims to find historical basis to justify the reform of zoning system to promote both specialized and mixed land uses. When the zoning system was first introduced in Japanese colonial period by Chosun Planning Ordinance enacted in 1934, Special District within Manufacturing Area, and later within Residential, Commercial, and Mixed Areas respectively was institutionalized for specialized land uses, though it was not actually designated. When City Planning Law was enacted in 1962, Special District was substituted by Exclusive Areas (Exclusive Residential Area, Exclusive Manufacturing Area). Meanwhile Undesignated Area was designated for mixed land uses by Chosun Planning Ordinance, and later it was converted mostly into Mixed Area and partially into Green Area. Finally Mixed Area was substituted by Semi-Areas (Semi-Residential Area, Semi-Manufacturing Area) by City Planning Law in 1962. These demonstrate that Korean zoning system needs to revive the tradition that clearly promoted both specialized and mixed land uses.

Zoning has long been criticized for its negative effects and has been taken for granted that zoning works as a hurdle to urban diversity. Responses in the US have emphasized more fine-grained zoning approaches that plan mixed use. This paper introduces and evaluates Seoul's zoning system as a possible alternative. While US zoning regulations have relied on distinguishing ever larger numbers of land use zoning categories, Seoul has opted to integrate new land uses into existing classifications, allowing for greater flexibility of use in each zone. Using municipal building records to evaluate land use in three mid-density residential districts, this paper demonstrates that Seoul's flexible zoning is capable of producing diverse mixed use neighborhoods. It then highlights the potential downside of this approach, showing that flexibility allows for the commercialization and sectoral gentrification of residential districts. It concludes by suggesting that a combination of flexible zones and more fine-grained plans would capture the advantages of both US and Korean planning.

To improve urban safety there is an increasing social need for environmental design against crime, which is defined as the creation of inconvenient environments or situations for criminal offenders. By using a cluster analysis, we aimed to clarify crime occurrence patterns from the perspective of land-use. Osaka Prefecture was chosen as the study area because it has the highest crime rate in Japan. The results revealed that there are six patterns of crime occurrence, and that cities of medium-level of mixed land-use have the lowest crime rates.

This investigation is to question as to whether and how much urban residential superblocks have changed the uses of facilities, as compared with original zoning plan. The difference between the original plan for 'land use' in 1960's and current 'building uses' has been examined on six superblocks in Seoul, and the reasons for change were analyzed. Investigation results are as follows: As the original urban planning was intended for use-purification by the subdivision of zones in a superblock through zoning, current buildings uses are different from the land-use. Commercial facilities are located in residential zone along community paths because of the necessity, and business buildings are placed on the appropriate-sized lots in the middle of residential blocks, due to the need of small and low-rent offices. Also, different types of residence have been built on convenient locations in commercial zone to meet various housing needs. In conclusion, the current zoning system plays a role of controling the volume of buildings rather than the use of land. Therefore, mixed use of land, not functional separation, becomes a natural phenomenon taken place in the contemporary cities, and it is high time to adopt a mixed-use zoning system.

Background: This study investigated the variation of soil organic carbon in four land cover types: natural and mixed forest, cultivated land, Eucalyptus plantation and open bush land. The study was conducted in the Birr watershed of the upper Blue Nile ('Abbay') river basin. Methods: The data was subjected to a two-way of ANOVA analysis using the general linear model (GLM) procedures of SAS. Pairwise comparison method was also used to assess the mean difference of the land uses and depth levels depending on soil properties. Total of 148 soil samples were collected from two depth layers: 0-10 and 10-20 cm. Results: The results showed that overall mean soil organic carbon stock was higher under natural and mixed forest land use compared with other land use types and at all depths ($29.62{\pm}1.95Mg\;C\;ha^{-1}$), which was 36.14, 28.36, and 27.63% more than in cultivated land, open bush land, and Eucalyptus plantation, respectively. This could be due to greater inputs of vegetation and reduced decomposition of organic matter. On the other hand, the lowest soil organic carbon stock under cultivated land could be due to reduced inputs of organic matter and frequent tillage which encouraged oxidation of organic matter. Conclusions: Hence, carbon concentrations and stocks under natural and mixed forest and Eucalyptus plantation were higher than other land use types suggesting that two management strategies for improving soil conditions in the watershed: to maintain and preserve the forest in order to maintain carbon storage in the future and to recover abandoned crop land and degraded lands by establishing tree plantations to avoid overharvesting in natural forests.

In recent years, the planning of livable communities has emerged as a new paradigm. The concept of livable communities is related to both the spatial balance of working, playing, and living and the promotion of green modes of transportation, such as walking and biking. This study uses a disaggregate travel survey conducted by the Seoul Metropolitan Area in 2006. I applied a multi-level random intercept logit model to estimate the effects of land-use characteristics on the choice of green modes, holding a traveler's socio-demographic characteristics constant. The empirical results show that higher density and more mixed land-use development encourages people to walk and bike even when individuals have the same socio-economic characteristics. This paper demonstrates that land-use planning by itself can play a role in the creation of livable cities and the decline of greenhouse gas production.

The intent of this study is to propose future planning guidelines and directions of the mixed-use buildings in the residential land development district in country-side cities, based on the concept that the neighborhood facilities are to be strategically laid out in a convenient location and planned in a proper manner for a healthy, safe, friendly and new neighborhood environment. For this purpose, seventeen mixed-use buildings which had been built in Shin-Eum housing development district in Gimcheon from 1995 until 2004 were chosen and investigated in terms of architectural characteristics in that process with surveying and analyzing those. The scope of investigation on case studies was that site size would be below 400 square meters, total area below 1500 square meters, and the number of stories below five stories high on the ground. Method of investigation on those was through field investigation, field photographs, recordings and drawings on those. Investigative contents have been divided and analyzed into the quantitative and qualitative factors in urban and architectural dimension. From results of quantitative investigations, five planning guidelines or directions could be obtained. From results of qualitative investigations, five planning guidelines or directions could be obtained. The criteria will be applied to new architectural developments of the neighborhood facilities linked with the small shops.

Recently, the interest in the mixed-use development of various urban planning facilities has been increased, but the interest in the Mixed-use development of bus depots that is closely related to our daily life is insufficient circumstance so far. Accordingly, this study aims to realize the necessity for the mixed-use development of bus depots as methods to improve the living environment and use efficiently the land, and to suggest reasonable development directions by analyzing their physical character after classifying bus depots according to their position in the residential area. As the results of study, bus depots have different properties according to their position in residential area and have the problem of space shortage. Also, many things such as location of entrances, the finish method of edge of bus depot's area are affected by the surrounding environment. So development plan to consider the each condition is required.
