Brownfield sites are beginning to be considered as potentially useful areas for landscape design and planning, with post-industrial areas such as water treatment facilities and military training bases being converted into useful landscapes such as parks and recreation areas. These redevelopments bring broad benefits through revitalizing communities and increasing property values, thus, increasing the demand for comprehensive management and planning policies. This study examines changes in U.S. brownfield policies and programs and, identifies their periodic characteristics over the thirty years since the Superfund program was introduced in 1980. A descriptive and interpretive approach was utilized, focusing specifically on a time sequential analysis of the data gathered from the overview of the Environmental Protection Agency's web-based documents and related literature. The primary changes in and characteristics of programs and policies were analyzed and divided into three periods : environmental protection, remediation and reuse, and comprehensive planning. Four major features were identified: relaxation and readjustment of regulation, diversification of support programs, a mix of top-down and bottom-up approaches, and database system building. The study examines how common brownfield problems such as site identification difficulties and assessment and remediation cost have been dealt with in the regulatory context and has implications for future policies and programs for effective brownfield planning and management in Korea.

This study was conducted on the counselors who work in university job centers and visiting students to analyze the relationship among counselors' calling, visitors' perception of counselors and work alliance perceived by the visitors and counselors. The data were collected from 110 counselors who are in charge of career counseling in university job centers and 208 visitors to the center, on which multiple regression analysis was performed. The results of this study are as follows. First, counselors' calling had positive effect on work alliance perceived by counselors (${\beta}=.48$, p < .01) with explanatory power of 25%. Counselors' calling had positive effect on work alliance perceived by visitors (${\beta}=.21$, p < .01) with explanatory power of 7%. Second, counselors' calling had positive effect on visitors' perception of counselors (${\beta}=.21$, p < .01) with explanatory power of 8%. Through these results, this study found out that counselors with high level of calling tend to form great work alliance while visitors tend to perceive that counselors with high level of calling are professional, trustworthy and likable.

A damage estimation method is presented for jacket-type support structure of offshore wind turbine using a change of modal properties due to damage and committee of neural networks for effective structural health monitoring. For more practical monitoring, it is necessary to monitor the critical and prospective damaged members with a limited number of measurement locations. That is, many data channels and sensors are needed to identify all the members appropriately because the jacket-type support structure has many members. This is inappropriate considering economical and practical health monitoring. Therefore, intensive damage estimation for the critical members using a limited number of the measurement locations is carried out in this study. An analytical model for a jacket-type support structure which can be applied for a 5 MW offshore wind turbine is established, and a training pattern is generated using the numerical simulations. Twenty damage cases are estimated using the proposed method. The identified damage locations and severities agree reasonably well with the exact values and the accuracy of the estimation can be improved by applying the committee of neural networks. A verification experiment is carried out, and the damage arising in 3 damage cases is reasonably identified.

This study was conducted to investigate nursing students' safety-climate: perception and performance of standard precautions for healthcare-associated infection control. We also identified actors influencing performance of standard precautions. Data were collected from 246 junior and senior nursing students at nine colleges in D city from July to September, 2016. The mean score of performance was significantly lower than that of perception in all areas of standard precautions. The biggest difference between perception and performance was in the usage of personal protective equipment and safe injection practices. We also detected significant positive correlations among safety-climate, perception, and performance of standard precautions. In the regression analysis, performance of standard precautions was influenced by safety-climate and grade accounting for 10.7% of variance. To improve healthcare-associated infection control among nursing students, safer and more supportive practical environments need to be provided, and new training strategies such as simulation education need to be expanded.

The purpose of this study was to investigate the effects of Maum meditation on anxiety, self-esteem and self-actualization of teachers and this is a one-group pretest-posttest design study. Three times of surveys were carried out for seven nights and eight days including July 25 - August 1, August 1 - 8, 2009 and January 2 - 9, 2010. Before and after Maum meditation, 108 teachers in the faculty training filled out the structured questionnaire. The data were analyzed by SPSS WIN 12.0. The results showed that there was a significant difference in self-esteem of the teachers between before and after Maum meditation(p=.001). The self-actualization of the teachers was also found to be significant before and after the meditation(p=.002). Maum meditation decreased the teachers' anxiety level and improved considerably the self-esteem and self-actualization level. So it is necessary to develop the self-concept questionnaire that can support the mental health promotion intervention program.

Decline of pine forests happens in Korea due to various disturbances such as insect pests, forest fires and extreme climate, which may further continue with ongoing climate change. For conserving and reestablishing pine forests, understanding climate-induced future shifts of pine tree distribution is a critical concern. This study predicts future geographical distribution of Pinus densiflora, using Maximum Entropy Model (MaxEnt). Input data of the model are locations of pine tree stands and their environmental variables such as climate were prepared for the model inputs. Alternative future projections for P. densiflora distribution were conducted with RCP 4.5 and RCP 8.5 climate change scenarios. As results, the future distribution of P. densiflora steadily decreased under both scenarios. In the case of RCP 8.5, the areal reductions amounted to 11.1% and 18.7% in 2050s and 2070s, respectively. In 2070s, P. densiflora mainly remained in Kangwon and Gyeongsang Provinces. Changes in temperature seasonality and warming winter temperature contributed primarily for the decline of P. densiflora., in which altitude also exerted a critical role in determining its future distribution geographic vulnerability. The results of this study highlighted the temporal and spatial contexts of P. densiflora decline in Korea that provides useful ecological information for developing sound management practices of pine forests.

In South Korea, the results of R&D in science and technology are submitted to the National Science and Technology Information Service (NTIS) in reports that have Korea national science and technology standard classification codes (K-NSCC). However, considering there are more than 2000 sub-categories, it is non-trivial to choose correct classification codes without a clear understanding of the K-NSCC. In addition, there are few cases of automatic document classification research based on the K-NSCC, and there are no training data in the public domain. To the best of our knowledge, this study is the first attempt to build a highly performing K-NSCC classification system based on NTIS report meta-information from the last five years (2013-2017). To this end, about 210 mid-level categories were selected, and we conducted preprocessing considering the characteristics of research report metadata. More specifically, we propose a convolutional neural network (CNN) technique using only task names and keywords, which are the most influential fields. The proposed model is compared with several machine learning methods (e.g., the linear support vector classifier, CNN, gated recurrent unit, etc.) that show good performance in text classification, and that have a performance advantage of 1% to 7% based on a top-three F1 score.
