A Study on Assessment of Utilities of Urban Forest with Reference to User Satisfaction - Case Study of Apsan City Natural Park in Taegu -

Chan Yong Park 한국산림과학회 1991 한국산림과학회지 Vol.80 No.1

This study aims at identifying factors and variables which have significant effects on users satisfaction with recreational activities and facilities in Apsan city natural park and thereby establishing indicies of planning and/or development of urban forest. To test the causal models of this research, The data were gathered by self-administered questionnaires from 1,147 households in Taegu city which were selected by the multi-stage probabiling sampling method. The analysis of the data primarily consist of two phases : The fires analysis dealt with exploratory factor analysis which identified major factors involved in satisfaction with recreational activities and facilities in Apsan city natural park and the second analysis tested the fit of causal models of this research to the data using LISREI, methodology. LISREL refers to a general statistical model for analysis if Linear Structural RELationships among quantitative variables. Now a new verson of ;accompanying computer program, LISREL VI is available. LISREL IV is an improved to fit and test structural equation models which specify phenomena antler study in terms of putative cause and effect variables and their indicators. The variables in the structural equations may be observed measurements or latent variables The LISREL or casual model consists of the measurement and structural equation models. The measurement model specifies how the latent variables are measured in terms of the observed variables and is used to describe the measurement properties of the observed variable. The structural equation model specifies the casual relationships among the latent variable and is used to describe the causal effects. Latent variables of unobserved variables represent theoretical constructs. The LISREL model consists of two sets of unobserved variables, the dependent variables η, and the independent variable ξ, which are considered a cause of η in the system of linear structural relations: η=Βη_Γξ+ζ where Β and Γ are parameter matrices of direct causal effects and ζ is a vector of structural disturbance or residuals. The LI5REL computer program estimates the unknown coefficients of the structural equations and the covariance matrices of the residuals and measurement errors. Standard errors of all estimated paramated are provided along with chi-square tests of the fit of the models and structural hypotheses within the model. The most important advantage of LISREL comparing with multivariate analytic techniques is that is enables the researcher to test a theory. To use LISREL the researcher should have a priori theory to be tested. The factor analysis identified that three significant factors are involved in satisfaction with recreational activities and that five significant factors are inherent in satisfaction with recreational facilities. The three factors of satisfaction with recreational activities are mental relaxation, physical health, and calmness and the five factors related to satisfaction with recreational facilities are convenience Facility, linear physical exercise facility, viewing facility, space for repose and play, and climbing facility. The second phase analysis tested the tit of the causal models for satisfaction with recreational activides and facilities to the data and identified sadistically significant causal linkage among overall satisfaction with the park, other indigenous factors and exogenous variables. Overall fits of both causal models were goad. Among iudogenous factors, calmness and space for repose and play factors were identified as having significant effects on overall satisfaction. Exogenous variables which have significant effects on indogenous variables were also identified. These significant relationships represent important factors and variables that should be considered in planning and/or development of the city natural park. On the basis of there significant causal relationships implications for planning and/or development

현대사회의 쟁점과 문학교육 : 세대갈등과 문학교육의 전략

Intergenerational Conflict and Strategies of Literature Education Park, Yong-Chan This article focuses on the role of literature education to resolve the intergenerational conflict. This article deals with literary works in korean language textbooks mainly concerning intergenerational conflict. Intergenerational conflict comes from the difference in recognition of reality and values which each of generations have. The rapid social changes bring about the difference of historical events and cultural experience between each generations. This is a factor accelerating the intergenerational conflict. Since human life contains a conflict itself, the conflict is bound to be a main material in literature works. Intergenerational conflict in literature works is mainly presented as a form of the conflict between parents and child. Since intergenerational conflict takes on the aspects of vertical conflict, it is more serious than horizontal conflict within the same generation. The novels dealing with intergenerational conflict have been positioned as an important canon(正典) in the literary education fields. This article adopted Lee Tae-jun`s ?A Stone Bridge?, Park Wan-seo`s ?A Twilight?, Oh Seung-hee`s ?Meju which followed Grandmother? as main texts in discussion. The main cause of conflicts is mainly derived from the difference of value consciousness looking at the object. These three literary works show the conflict between characters whose values are different. These conflicts can be called a confrontation between characters grew up in a different culture. Intergenerational conflict is derived from an absence of communication between each generations about assessment of value. To resolve the conflict, The width of sympathy and understanding for each other is important. It is more desirable to expose the aspects of conflict rather than hiding it in order to find a solution more seriously. For the first, It is necessary to secure many education canon dealing with intergenerational conflict in the literature education fields. Next, in the process of teaching and learning, activities to understand the other side must be planned as a teaching strategies. Through these process, it makes the learner experience the empathy and communication with each other. At last, while the learner re-contextualize the conflicts on the basis of learned literary abilities, the learner also should develop the problem-solving skills in a new situation.

The Saemaeul Movement, which is the representative national campaign of Korea aimed at the development of local communities, has drawn a great deal of attention from home and abroad and formed an element of Korea``s national brand since 2000. Accordingly, this research was conducted for the purpose of constructing a memorial park in Shindo Village, Cheongdo County, North Kyoungsang Province, which is a home to the Saemaeul Movement. As the Saemaeul Movement is benchmarked by many countries around the world today, this research aims to communicate the spirit and social value of the movement and disseminate its effects of local community development in rural areas through the construction of a memorial park. In this study, the design motive of the memorial park was conceived through the historical review and case studies of the Saemaeul Movement. In parallel, theoretical study was also conducted on design techniques as the basis of this research. In consideration of the characteristics of a technical article, this research was conducted in several phases. In the first phase, the conditions of the site where the park construction was planned were analyzed and the direction of its development was set. In the second phase, the main theme and the basic principles of planning were established, and the contents of the park construction project were devised in detail. In the last phase, a comprehensive plan was established, including a space layout to accommodate activities, facilities and programs to be introduced to the park. The park construction site (106,000㎡) was divided into four zones (memorial zone, historical theme park, education zone and experience zone) based on circulation planning aimed at creating memorial space, and was linked to eco-friendly ecological space in consideration of environmental features. At a time when the Saemaeul Movement is being propagated across the world, the result of this study will help create a place for its memorial and play a pivotal role to boost international movements aimed at promoting co-prosperity across the global village. It will also bear significance as an example of theme-based park construction in a rural area and the invigoration of a local community.

Fabrication by welding may result in stress concentration regions in the joints and it may be caused by weld imperfections on geometrical discontinuities. Thus, fatigue strength of welded details was essential for fatigue design of welding structures. In this study, constant amplitude fatigue tests on load-carrying fillet welded specimen carried out, and fatigue strength were evaluated. Also, in this investigation an attempt is made to develop a new analytical model to predict the fatigue crack propagation life of fillet welded cruciform joints of SWS 490B steels containing lack of penetration defects with more accuracy. From the result of this study, fatigue crack growth characteristics of load-carrying fillet welded cruciform joints, containing lack of penetration defects are found to be influenced by the weld size and geometry.
