  • The primary goal of this research is to link two currently disconnected literature; the history of urban redevelopment and the one of urban parks and open spaces in the United States (US). Through this exercise, this study attempts to reveal examples of urban parks and open spaces that have yielded economic effects, and emphasize their possibility as a measure of urban redevelopment. Five phases are presented, starting with two Pre-World War II urbanization periods, and three subsequent periods of Post-World War II urban redevelopment (1940s~1960s, late 1960s~1970s, 1980s~present). While urban parks in the 19th century urbanization period held a preeminent place in urban design, policy and economy, ensuing depression and World War II diminished their role as a channel to ease unemployment. In the first phase of urban redevelopment, the economic motive to build open space was to boost the appeal of specific locales in order to draw people and businesses back to a neglected city. In the second phase, public effort to create and maintain urban parks and open spaces declined due to the budget austerity, instead, community open spaces flourished through the voluntary actions and helped neighborhoods to regain desirability. In the third phase, the aspirations and functions of such projects resemble their forerunners of the first phase, but their targets extended to global businesses and elites.

  • The purpose of this study is to identify the influence of the GRIT of teenagers on their career preparation behaviors and verify whether there is a mediating effect between GRIT and the career preparation behaviors with a view to assisting such career preparation behaviors. For this study, an analysis was conducted using AMO 22.0 and SPSS Statistics 22.0, with 426 teenagers in general middle schools. The findings of the analysis were as follows. First, the GRIT of teenagers had a significant impact on social support and career preparation behaviors. Social support had a significant effect on career preparation behaviors, as well. Second, in the relationship between the GRIT of the teenagers and their career preparation behaviors, social support, and the sub-elements of the social supports, which are emotional support, information support, evaluatory support, and material support, all had mediating effects. These study findings showed that GRIT and social support were influential factors upon career preparation behaviors. Therefore, in order to promote career preparation behaviors among teenagers, it is necessary to provide social support in the family and school environments, and it is also helpful to enhance the GRIT, which is an individual trait.

  • The cultural cluster in Chuncheon was initiated in the late 1990s with the combination of diverse components, which were companies, a local government entity, educational institutions, and human resources. In order to hold ability of standing on its own way in a hard time when the local cultural industries could not had developed by themselves, it urgently required the encouragement policy in the name of industry development. GIMC (Gangwon Information & Multimedia Corporation) was established in this situation, and policy strategies for promoting the cultural cluster was decided on the basis of GIMC's strategies. This article analyzes the evolution process of the local cluster and suggests characteristics of its every stage--initiation, development, and decline--on the basis of cluster competition concept because of the problem to deal with the evolution process of cluster from the existing viewpoint. This article finds out that Chuncheon cluster embarked on cultural cluster strategies without concerning basic elements which had to be prepared from the initial stage. This problem worked as the serious obstacle hampering development of Chunchen cluster. This problem was the matter of policies in providing a direction of industry development as well as leading a local cultural cluster and led to a result of weakening the connection among cluster components. As a result, this article shows that the current status of Chuncheon cultural cluster is being entered the decline stage, and, therefore, suggests that the advanced policy to promote cluster for a next round is urgently needed. Stable closing the first round of cultural cluster policies and thorough preparation for the second round is the only practical solution to minimize side effects of cluster decline. It is the prerequisite to restore trust and, at the same time, reinforce relationship between members who consist of Chuncheon cultural cluster.

  • To successfully create a low-carbon landscape in order to become a low-carbon city, it is necessary to understand the dynamics of artificial greening's resources on a multi-scale. Additionally, the effects of carbon storage should be quantitatively evaluated. The purpose of this study is to simulate and evaluate the changes in carbon storages of artificial ground trees using system dynamics throughout a long-term period. The process consisted of analyzing the dynamics of the multi-scale carbon cycle by using a casual loop diagram as well as simulating carbon storage changes in the green roof of the Gangnam-gu office building in 2008, 2018, 2028, and 2038. Results of the study are as follows. First, the causal loop diagram representing the relationship between the carbon storage of the artificial ground trees and the urban carbon cycle demonstrates that the carbon storage of the trees possess mutual cross-scale dynamics. Second, the main variables for the simulation model collected 'Biomass,' 'Carbon storage,' 'Dead organic matter,' and 'Carbon absorption,'and validated a high coefficient of determination, the value being ($R^2$=0.725, p<0.05). Third, as a result of the simulation model, we found that the variation in ranking of tree species was changing over time. This study also suggested the specific species of tree-such as Acer palmatum var. amoenum, Pinus densiflora, and Betula platyphylla-are used to improve the carbon storage in the green roof of the Gangnam-gu office building. This study can help contribute to developing quantitative and scientific criteria when designing, managing, and developing programs on low-carbon landscapes.

  • The purpose of this study was to analyze the effects of internal organizational culture attributes on job performance and job satisfaction. Data collection was conducted from December 8, 2014 to December 20, 2014 through a self-enforced questionnaire at 500 general hospitals in Gyeonggi-do. First, the organizational cultural attributes of hospitals had a statistically significant effect on job performance. Second, organizational cultural attributes had a statistically significant effect on job satisfaction. Third, job performance had a statistically significant effect on job satisfaction. For communication, organizational development and the future of the organization as well as organizational attributes and systems of the organization were shown to increase job performance and job satisfaction, communication with seniors and colleagues, roles, and responsibilities between departments. Organizational culture had more organizational attributes than individual ones, which affects the work and behavior of the organization members. Therefore, in order to survive competition, hospitals require accurate diagnosis of hospital organization culture, maximize effectiveness of organization culture, and a desirable hospital culture. In addition, management should provide employees with a clear mid- to long-term vision to ensure that the objectives of the hospital and the goals they pursue are consistent.

  • Petasin extracted from Petasites japonicus leaves has been well known to be effective in the treatment of allergic asthma. This study was carried out to optimize the extraction process of petasin from P. japonicus leaves by response surface methodology (RSM). The dried powder of P. japonicus leaves was extracted at ethanol concentrations ranging from 40% to 80%, extraction rpm ranging from 125 rpm to 225 rpm, and extraction time ranging from 1 to 3 hours. The effects of the extraction conditions on the dry yield and petasin content of the extracts were investigated using a second-order Box-Behnken design. The petasin content was significantly affected by ethanol concentration, extraction rpm, and extraction time, tending to increase more with increasing ethanol concentration. The optimum condition for petasin extraction from Petasites japonicus leaves was 79.92% in ethanol concentration, 178.10 rpm in extraction rpm, and 2.06 hours in extraction time, respectively.

  • The classification accuracy of land cover has been considered as one of the major issues to estimate pollution loads generated from diffuse landuse patterns in a watershed. This research aimed to assess the effects of the acquisition methods and sampling size of training reference data on the classification accuracy of land cover using an imagery acquired by optical sensor(OPS) on JERS-1. Two kinds of data acquisition methods were considered to prepare training data. The first was to assign a certain land cover type to a specific pixel based on the researchers subjective discriminating capacity about current land use and the second was attributed to an aerial photograph incorporated with digital maps with GIS. Three different sizes of samples, 0.3%, 0.5%, and 1.0% of all pixels, were applied to examine the consistency of the classified land cover with the training data of corresponding pixels. Maximum likelihood scheme was applied to classify the land use patterns of JERS-1 imagery. Classification run applying an aerial photograph achieved 18 % higher consistency with the training data than the run applying the researchers subjective discriminating capacity. Regarding the sample size, it was proposed that the size of training area should be selected at least over 1% of all of the pixels in the study area in order to obtain the accuracy with 95% for JERS-1 satellite imagery on a typical small-to-medium-size urbanized area.

  • Objectives: The purpose of this study identified the perceived quality of parent-child relationships and attitudes toward filial duty contracts among young adult children. Also, this study is to examine the effects of sociodemographic characteristics and perceived quality parent-child relationships on the attitudes toward filial duty contracts and the requirement for filial duty contract details. Method: For this study, a survey was conducted with 210 college student children in young adulthood in Seoul and Gyeonggi-do. The questionnaire consisted of the 'Attitudes toward Filial Duty Contracts Scale', the 'Requirement for Filial Duty Contract Details Scale', and the 'Quality of Parent-Child Relationships Scale' with a demographic questionnaire. Specifically, the Attitudes toward Filial Duty Contracts Scale consisted of the support for contract, the intention of contract, and reservation contract amount on young adult children's mind. Data were analyzed by means of descriptive statistics and multiple regression analysis. Results: The major findings of this study are as follows: First, young adult children reported the relationship with mother better than father's and mid levels of support and intention of filial duty contract. They also showed that their reservation contract amount on their mind was about 500 million won. Second, the multiple regression analyses revealed that gender and pride of one's father positively related to their support for filial contract. Also, gender, the pride of one's father, and emotional closeness to one's father significantly affected their intention of filial contract. In addition, among the variables, only monthly family income significantly predicted their reservation contract amount. Finally, the multiple regression analyses revealed that birth order and gender significantly predicted the normative duty contract. Also, the pride of one's father significantly affected the emotional support contract. However, filial duty contract details such as caregiving for sick parents, physical support, and economic support have been found to be meaningless. Conclusions: The findings suggest that preparative education of aging for parents who are considering making the filial duty contracts with their children should include some realistic advice. These pieces of advice include their parent-child relationship and consideration of their own overall asset sizes.

  • There has neither been enough research on how to approach the concept of active aging through an integrated view nor an examination to verify the relationship between preparation for old age and active aging in later life. Therefore, this research aims to verify that the elderly, who have prepared for their later life, affected their active aged life. In addition, by setting up self-efficacy and social support as mediator in the research model, this paper looks into the psycho-social resource mechanism of the relationship in depth. In order to verify the correlation of two variables, the Seoul welfare panel data, a mediating model structured by psycho-social resources created by Seoul welfare foundation in 2010, was used. The total sample size was a group of 1,492 elders aged over 65. When it came to our research methods, structured equation analysis was applied to verify the mediating effect and theoretical background. The results revealed that physical preparation, financial preparation, social preparation and leisure preparation directly affected their active aging level positively, thus, psycho-social resources showed a partial mediating effect between preparation for old age of the past and active aging level. The research implications are as follows. First, this research makes an effort to approach the concept of preparation for old age with an integrated perspective through making a construct by entire preparation types. Second, it will attempt to verify the relationship between preparation for old age in the past and active aging in terms of multi-dimension is meaningful. Third, this research reveals the function of psycho-social resource, self-efficacy and social support within the relationship. As far as the partial mediating effect is concerned, preparation for old age education for the middle-aged class should be modified as a decent field to enhance of the elderly.
