본 연구는 지속적인 여객 및 화물량의 증가로 기존 수송수단이 포화에 이른 실정에 새로운 교통수단으로 추진한 고속철도 사업에 대해, 고속철도 개통 후 단기간에 드러난 이용현황 및 문제점을 도출해 기선방안을 제시하고자 한다. 이를 위해 관련 단체 및 기관의 자료를 수집 분석하였으며, 설문조사를 수행하여 결과를 도출하였다. 또한 광범 위한 고속철도 사업의 특성아래 여객 부문에 대한 대중교통 측면으로 연구의 범위를 한정하였다. 고속철도 개통 후, 여객 및 화물 수송의 형태에는 단기간이나마 큰 변화가 있는 것으로 나타났으나 그에 반해 고속철도의 이용에 있어서 주목할 만한 문제점 또한 조사되었다. 주요 사항으로는 역방향 유해성, 일반열차로의 불편전이, 터널통과시의 소음 등으로서 이는 개통 초기 고속철도에 대한 그릇된 대국민 인식을 가져오게 함과 동시에 향후 개인들간 교통수단 선택에 있어서까지 그릇된 영향을 끼칠 수 있다. 현재 각각의 문제점에 대한 개선방안으로 일반열차 확대 및 할인혜택, 점진적인 순방향 좌석으로서 교체 및 소음 저감방안을 위한 연구 용역 등이 실행되거나 준비되고 있으나 그에 대한 뚜렷한 개선 징후는 아직 미미한 상태로 분석되고 있다. 본 연구에서 실시한 설문조사 결과 아직까지는 고속철도에 대한 인식이 긍정적인 수준을 보이고 있으나 개별 문제점에 대한 좀더 깊은 고찰과 개선안 제시가 이루어진다면 향후 고속철도에 대한 대국민 인식을 한 단계 더 높여, 그 이용을 활성화 시킬 수 있는 좋은 기회가 될 것으로 판단된다.

This study is an ethnographic case study aiming at understanding the environmental education (EE) classes of 'Discretionary Activity' which has recently been introduced into Korean middle school curricula. To show the characteristics of the classes, researcher described the phenomena unique to two schools. Two middle school teachers were included in this study as research participants. Qualitative approaches were used to understand the status quo of school environmental education, teachers's perspectives on EE and their expectations for learners' changes. Data were gathered using the methods of participant observation during two school terms and in-depth interview with two teachers and nine students. Ethnographic analysis/interpretation methods such as domain analysis were used to analyze the data. To verify the research methodology and conclusions, triangulation, members checking and peers debriefing were used. Research questions emerging through the circulative research process include 1) what are the teachers' perspectives on EE and how do the teachers' perspectives affect their EE teaching? 2) what are the teachers' expectations for learners' changes and how are teachers/researcher able to perceive learners' changes? Two research participants have different life experiences and perspectives on environment and EE. The perspectives had influence on the selection of the contents and the styles of their teaching. Teachers' expectations for learners' changes were also different according to the styles of the teaching.

In recently years, there are cyber-weapon aim to national infrastructure such as 'stuxnet'. Security experts of the world are paying attention to this phenomenon. The networks which controls traffic, subway, waterworks of the city are safe from threats such as computer virus, malware, because the networks were built on closed-networks. However, it's about time to develop countermeasure for the cyber-weapon. In this paper, we review status-quo of the control systems for metropolitan infrastructure and analyze the risk of industrial control system in SCADA(Supervisory Control And Data Acquisition) network. Finally, we propose a security model for control systems of metropolitan infrastructure.

This study is the application of a choice experiment to assess Mekong Delta urban households' preferences and motivations for ecosystem conservation in the U Minh forest. The study applied a choice modeling approach to estimate the economic values of the proposed ecosystem conservation program in the U Minh forest by accessing urban consumer preferences and their willingness to pay for the project. Discrete choice experimental data was collected from 450 residents in the cities of the Vietnamese Mekong Delta. The multinomial logit model was employed to identify consumer's stated preferences for the environmental and sustainability attributes of the conservation project. The results showed that Mekong Delta urban residents paid much attention to the proposed project to protect and develop the U Minh forest. In addition, the results showed that higher education, income, and knowledge of the U Minh forest revealed a higher likelihood of selecting the project, while the older residents would select the status quo more than the younger ones. The study also proved that the effect of participation had a strong impact on the willingness to pay for the project. The findings could be useful for policymakers to take action to raise resident's awareness and willingness to pay for the U Minh forest project.

Antibiotics are commonly prescribed medications in the hospice and palliative care setting, as well as in many other healthcare settings. The overuse or negligent use of antibiotics is associated with the harmful consequence of fostering the development of antibiotic-resistant pathogens. Thus, there is an urgent need to critically examine and audit antibiotic use in all aspects of healthcare. In the status quo, there is a lack of consistent standards and guidelines surrounding the use of antibiotics in hospice and palliative care settings, leading to significant variations in how antibiotics are prescribed and administered in end-of-life care. It is apparent that greater thought needs to go into antibiotic decisions for patients receiving hospice or palliative care, especially considering the harmful consequences of the overprescription of antibiotics. The literature suggests that many clinicians prescribe antibiotics inappropriately for patients who would not benefit from their use or prescribe them without adequate documentation. Clinicians should be deliberate about when they prescribe antibiotics and adhere to the appropriate documentation standards and procedures within their institution or community. Future research should seek to generate generalizable knowledge about which patients will benefit most from antibiotic therapy during end-of-life care.
