The absolute area of wetland accounts for 0.3% of the whole Beijing. We have studied the current environmental situations of Beijing's wetland and the changes in the key wetland supported by Remote Sensing(RS) technology. The result shows that the areas of wetland are reducing year by year and the quality of ecological environment is dropping year by year. At last, we analyze the factors that influence the change of wetland and propose some constructive suggestions according to current problems existing in Beijing's wetland.

The construction industry in the local areas business as the archetypal local one is effectuating industrial production, create employment and so on to perform a significant part in keeping local economy also reviving sluggish economy. The construction stagnation in market may cause severe economic depression in local which leads to having a crippling impact on local constructive industry, in terms of the phenomenon is on the interrelation between the local construction industry and local economy, with regard to local economy which is not covered by firm based industries is wield strong influenced over by construction industry. The object of this study is to research possible improvement factors on the preferential basis by only companies' efforts, therefore the policy of government or local self-governing body in support may be unnecessarily involved after grasping faced practical problems at regional construction companies from analysing the present condition of local construction marketplace and companies.

The purpose of this paper is to evaluate the impact of green practice on firm's performances. It focuses on the performance of the firm that already accredited as an excellent green practice firm by the Corporate Governance Service. The regression analysis method was chosen to measure firm performance. This paper also investigate how the performance of green practice are related to some factors such as levels of accredition, R&D cost, and R&D capitalization. This result will give an insight of constructive directions for increasing of firm performance.

Universities in Korea have driven universities' new attempts to adopt more learner-centered and active learning in English. Problem-based Learning (PBL) is one of the well-known constructive teaching and learning methodologies in higher education. Our research goal was to design and develop the optimal PBL practices for a college physics course taught in English to promote learning and course satisfaction. For four semesters, we have tried and adjusted PBL components, and looked at the trend of the exam scores and group work achievement in each semester. We found that the number of problems and the duration of problem solving are the critical factors that influence the effect of PBL in a college physics course taught in English by going through iterative implementation. The iterative process of applying, designing, and constructing PBL to physics classes was meaningful not only in that we have found the optimal PBL model for learning a college physics course, but also in that we have been reflecting on the continuous interaction with learners during the course.

Software cost and schedule estimation is usually based on the estimated size of the software. Advanced estimation techniques also make use of the diverse factors viz, nature of the project, staff skills available, time constraints, performance constraints, technology required and so on. Usually, estimation is based on an estimation model prepared with the help of experienced project managers. Estimation of software cost is predominantly a crucial activity as it incurs huge economic and strategic investment. However accurate estimation still remains a challenge as the algorithmic models used for Software Project planning and Estimation doesn't address the true dynamic nature of Software Development. This paper presents an efficient approach using the contemporary Constructive Cost Model (COCOMO) augmented with the desirable feature of fuzzy logic to address the uncertainty and flexibility associated with the cost drivers (Effort Multiplier Factor). The approach has been validated and interpreted by project experts and shows convincing results as compared to simple algorithmic models.

Purpose: This study was done in order to identify nursing students' professional self-concept, self-leadership and clinical competence and to analyze the correlation among the variables and the factors influencing clinical competence. Methods: The research participants were 294 senior nursing students in the nursing departments of 3 universities located in Jeollabuk-do. The students had completed 3 semesters of clinical practice. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and Multiple Regression. Results: Participants' scores for professional self-concept, self-leadership, clinical competence were $2.78{\pm}0.36$, $3.63{\pm}0.47$, $3.80{\pm}0.40$ respectively. Professional self-concept, self-leadership and clinical competence had positive correlations. Factors influencing nursing students' clinical competence included professional self-concepts in professional practice, self-expectations in self-leadership, constructive thinking, self-compensation and self-criticism in that order, and these variables explained 48%of the variance in clinical competence. Conclusion: Based on these results, it is important to develop and apply educational programs to increase professional self-concept and self-leadership in order to improve nursing students' clinical competence.

Purpose: The purpose of this study was to identify the level of knowledge about dementia and to find the related factors in middle-aged adults. Method: The research design was a descriptive study by using a constructive self-report questionnaire with 34 items. Data were collected from 397 middle-aged adults using structured questionnaire. Data analysis was done by SPSS/WIN Programs using frequency, range from minimum to maximum, percentage, mean, SD, ${\chi}^2-test$, t-test, ANOVA, and Duncan's Multiple Range test. Results: The rate of correct answer of middle-aged adults was 68.7%, showing the mid-level of knowledge about dementia. There were significant differences according to age, education, marital status, job, income, information and information sources for dementia in middle-aged adults. Conclusion: These results indicate that Korean middle-aged adults need more education and counseling on dementia. Further studies are needed to overcome regionalism in sampling of this study and to develop standard measuring tools for the level of knowledge about dementia.

The purpose of this study were to analyze characteristics of pre-service chemistry teachers' practice teaching and to investigate the relationship between their practice teaching characteristics and the view of learning. Three pre-service chemistry teachers were selected for this study. Their 9 practice teaching videos that recorded during practice teaching were observed, transcribed, and analyzed. Responses of questionnaires about their view of learning and interviews were transcribed and analyzed. Almost all of the characteristics of pre-service teachers' practice teaching seemed to be reflected in their view of learning. Pre-service teacher K had a lot of constructive view of learning, so comparatively many features of constructivism was presented in practice teaching. Pre-service teacher M had a lot of traditional view of learning, so many traditional features appeared in practice teaching. However, sometimes pre-service teachers' view of learning did not appear to their practice teaching because of several factors. In particular, a few cases that constructive view of learning was not reflected in the practice teaching appeared, especially pre-service teacher H. Factors were the practice school's conditions and the effects of tutors.
