With the rapid urbanization and growing energy use intensity in the built environment, the glazed curtainwall has become ever more important in the architectural practice and environmental stewardship. Besides its energy efficiency roles, window has been an important transparent component for daylight penetration and a view-out for occupant satisfaction. In response to the climate crisis caused by the built environment, this research focuses on the study of net-zero energy retrofitting by using a new building integrated photovoltaic (BIPV) curtainwall as a sustainable alternative to conventional window systems. Design variables such as building orientations, climate zones, energy attributes of BIPV curtainwalls, and glazed area were studied, to minimize energy consumption and discomfort hours for three cities representing hot (Miami, FL), mixed (Charlotte, NC), and cold (Minneapolis, MN). Parametric analysis and Pareto solutions are presented to provide a comprehensive explanation of the correlation between design variables and performance objectives for net-zero energy retrofitting applications.

In a changing environment of parallel management, members must respond more flexibly to customers and have the maximum service spirit, which makes servant leadership more important than the existing leadership style. This study will examine the impact of servant leadership on trust toward supervisor and the impact of trust toward supervisor on change-oriented behaviors and job exhaustion. Finally, this study will also analyze the moderating effect of organizational support in the relationship between servant leadership and trust toward supervisor. A survey questionnaire was conducted on nurses in university hospitals and general hospitals located in Busan. First, growth support, community building, and stewardship among servant leadership had a positively significant influence on trust toward supervisor but did not significantly influenced vision suggestion. Second, trust toward supervisor had a positively significant influence on change-oriented behaviors. Third, trust toward supervisor had a negatively significant influence on job exhaustion. Fourth, the interaction effect between the independent variable stewardship and moderating variable organizational support was significant on the dependent variable trust toward supervisor, but interaction effect between the independent variables that were vision suggestion, growth building, and community building and moderating variable organizational support was not significant.

Objectives: The purpose of this study was to examine how the dentist's servant leadership affects the happiness index of dental hygienists. Methods: The subjects were 221 dental hygienists that have been working at dental clinics or dental hospitals. The data were analyzed using SPSS Version 20.0 (IBM Co., Armonk, NY, USA). An independent t-test and one-way ANOVA analysis were conducted to examine the difference in the happiness index of dental hygienists according to general characteristics. The independent t-test was conducted to examine organizational culture and happiness index according to upper and lower group based on the mean score for servant leadership. Pearson's correlation analysis was used to examine the correlation among key factors. Multiple regression analysis was conducted to identify factors influencing the happiness index of dental hygienists. Results: According to the analysis, there was a statistically significant positive correlation between the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists. However, a stewardship of the dentist's servant leadership factors was not found to have any correlation with the market culture. A multiple regression analysis was performed after including the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists. Meanwhile, the stewardship and community-building effect of the dentist's servant leadership had a statistically significant effect on the happiness index of dental hygienists. Consequently, a higher servant leadership factor in dentists was correlated with a higher happiness index of dental hygienists. Conclusions:The findings show that the dentist's servant leadership affect the happiness index of dental hygienists. Therefore, effective intervention and education programs related to the dentist's servant leadership and sound organizational culture are necessary to enhance dental hygienists' happiness index. Additionally, a follow-up study will determine the causal relationship among the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists, considering organizational members and the environment of the dental clinics.

Background : The Antimicrobial Stewardship Program promotes interdisciplinary interventions and targeted recommendations for the proper utilization of antibiotics. In particular, the aim of the program is to avoid indiscriminate use of broad-spectrum antibiotics based on the documented literature on the significant impact of unsystematic usage of antibiotics on the distribution of antibiotic-resistant microorganisms. To improve the care process for pneumonia treatment using antimicrobial agents, institution-level guidelines were established and disseminated at the Seoul National University Bundang Hospital in April 2016. In this study, we evaluated changes in the physicians'antibiotic prescribing patterns both before-and after-the implementation of the guidelines. Methods : The electronic medical records of inpatients who were prescribed with one or more antibiotics in May 2014 (Group A) and May 2016 (Group B) were reviewed. Data on demographic characteristics, clinical outcomes, and antibiotic prescriptions were collected and the prescription records were compared both before- and after- the implementation of the guidelines. Results : A total of 180 patients were included in the study: 77 patients in group A and 103 patients in group B. The baseline characteristics of the patients were not significantly different between the two groups. Community-acquired pneumonia was the most common diagnosis in both the groups and the difference was not significant (68.8% vs. 67.9%; p=0.67). The type of antibiotic prescriptions used for empirical treatment was not different between the two groups. The most commonly prescribed empirical antibiotics were cephalosporins, with no significant difference (p=0.31). One of the most inappropriately used antibiotics was piperacillin/tazobactam and the rate of prescription was similar in both the groups (p=0.68). The rates of appropriate empirical selection of antibiotics remained unaltered between the two groups (67.5% vs. 71.8%; p=0.53). Conclusions : Implementation of the guidelines only exhibited no significant effect on the antibiotic prescribing patterns of physicians for the treatment of pneumonia. To improve the adequate use of empiric antibiotics, more active interventions and closer monitoring of the feedbacks should be additionally considered and evaluated in future studies.

Over the past decade, clubroot has emerged as a major constraint to canola (Brassica napus) production in central Alberta, Canada. The number of fields with confirmed P. brassicae infestations in Alberta has increased steadily from 12 in 2003 to nearly 2,000 in 2014. Management of clubroot on canola has focused on sanitization of field equipment, soil amendments to reduce viable pathogen populations, long rotations out of susceptible crops and cropping of resistant cultivars. Clubroot resistance is the most effective and economical method of disease mitigation, but the recent identification of isolated P. brassicae populations with novel virulence phenotypes capable of overcoming resistance in most canola cultivars highlights the variable nature and adaptability of the pathogen. Recent studies have shown slight reductions in pathogen populations through crop rotations, but much more substantial reductions in spore populations in heavily infested areas near field entrances using fumigants such as Vapam (metam-sodium) or Basamid (dazomet). Greenhouse trials showed that seedling emergence, plant height and root weight increased, while primary and secondary infection and disease severity decreased with increased Basamid dosage. However, field trials showed some phytotoxicity. Application of Vapam at rates of 0.4 to $1.6mL\;L^{-1}$ soil resulted in 12-16 fold reductions in clubroot severity and primary and secondary infection. Vapam also was effective in reducing clubroot severity and improving canola seed yield under field conditions. These studies underscore the need for good resistance stewardship and for the integration of multiple products and practices for successful management of clubroot on canola.

This study examines the cost and benefit (i.e., income) of the Forest Stewardship Council (FSC) rubber plantations in Thailand. The study attempts to identify the challenges to the implementation of FSC standards in rubber plantations in the country. A total of 60 rubber farmers in two Southern provinces, namely, Songkhla and Rayong, were interviewed through a standardized questionnaire to gather primary data. The study found that small-, medium- and large-sized FSC rubber plantations were worth investing in. All sizes of rubber plantations had similar values of benefit cost ratio (BCR). It was also found that the values of the discount payback period (DPP) of the three forms of FSC rubber plantations were 9-12 years, while the large rubber plantations had the highest internal rate of return (IRR) (19.0%). It implies that the large-size plantations had the highest values. The rubber farmers in the study area reported that they are facing a number of problems and hardships in implementing FSC standards, lacking knowledge and understanding of FSC, especially for preparing documentation. Therefore, the Thai government should take proper policy initiatives to remove all the problems and barriers in implementing FSC standards for the sustainable rubber production in the country.

This study aims at analysing the process of introduction and the development of the agri-environment policy of the UK and identifying the implication for the Korean government. The UK introduced the AES policy in order to reduce the negative impact of the farming practice on biodiversity and habitats. The initial process was only possible for the enormous research results on the relationship between the farming and environment. Since the UK launched the ESA scheme in 1987, it has extended the designated areas for four stages. Based on the success of the ESA scheme, it started CSS and other schemes. However, these had a modest success and were integrated into the CSS scheme, which from then on became the main measures of the AES in the UK. The whole process of the UK case tells us that the most important work for the start of the AES in Korea would be the necessity and feasibility of the environment protection measures in Korea which could be identified from academic and scientific research on the impact of agricultural practice on the rural environment in Korea.
