Life cycle assessment (LCA) on two different sludge treatment systems, on-site treatment and pipe-collected intensive treatment was performed to estimate the environmental impact in the aspect of global warming effect. As a main parameter of the estimation, $CO_2$ was chosen and quantified through the whole life cycle of the treatment systems including construction, operation and dismantlement. In this study, the changes of $CO_2$ production unit (CPU) by up-scaling n currently used sludge treatment processes were also calculated. As the result, a larger amount of $CO_2$ was exhausted from the construction step of intensive treatment system than that of on-site treatment system, because an additional pipe-collection system was needed in intensive treatment system. However, the total amount of $CO_2$ exhausted from whole life cycle including not only construction and dismantlement but also 15 year-operation and maintenance was reduced by appling intensive treatment.

초등학교 과학 영재들의 탐구 과제 수행 능력을 평가하기 위하여 대학 부설 영재교육원에 다니는 6학년 학생 56명을 대상으로 '먼지가 건강에 어떤 영향을 미치는가?'라는 주제에 대해 탐구하도록 하였다. 연구 과정에서 학생들로 하여금 제시된 주제에 대해 적절한 방법으로 탐구 과정을 설계하고 수행하여 그 결과를 제시하도록 하였다. 학생들의 보고서를 분석하기 위해 자료 조사, 예상, 탐구 설계 및 수행, 결과 제시, 결론 도출의 5개 항목에 대한 평가 기준과 채점 기준을 개발하였다. 보고서 분석결과, 학생들은 탐구 과정 중 자료 조사 활동 능력이 가장 우수했으며, 예상 활동, 탐구 설계 및 수행, 결과 제시, 탐구 결과 및 결론 도출의 순으로 능력의 차이가 나타났다. 구체적인 연구 결과를 제시하면 다음과 같다. 첫째, 자료 조사와 같은 기본적인 탐구 능력은 뛰어나지만 탐구 설계 및 수행, 결과 제시, 탐구 결과 및 결론 도출 등 높은 수준의 탐구능력은 부족했다. 둘째, 학생들은 자료 조사 활동에서 유난히 뛰어난 능력을 발휘하였는데, 이것은 정보화 사회의 발전에 따라 학생들의 기본적인 정보활용 능력이 향상되었기 때문으로 판단된다. 셋째, 외부에서 접한 정보를 인용하거나, 재활용은 할 수 있으나, 탐구 결과 및 결론 도출에 대한 채점 결과에서 볼 수 있듯이 그것을 자신의 것으로 소화하여 자신의 주장을 펼치는 능력은 상당히 부족하다.

Performing inspections for Hull Condition Monitoring and Assessment as stipulated in IACS unified requirements and IMO's Condition Assessment Scheme (CAS) IMO Resolution MEPC.94(46), 2001, Condition Assessment Scheme, IMO Resolution MEPC.111(50), 2003, Amendments to regulation 13G, addition of new regulation 13H involves a huge amount of measurement data to be collected, processed, analysed and maintained. Information to be recorded consists of thickness measurements and visual assessment of coating and cracks. The amount of data and increasing requirements with respect to condition assessment demand efficient computer support. Currently, due to the lack of standardization for this kind of data, the thickness measurements are recorded manually on ship drawings or tables. In this form, handling of the measurements is tedious and error-prone and assessment is difficult. Data reporting and analysis takes a long time, leading to some repairs being performed only at the next docking of the ship or making an additional docking necessary. The recently started ED funded project CAS addresses this topic and develops-as a first step-a data model for Hull Condition Monitoring and Assessment (HCMA) based on XML-technology. The model includes simple geometry representation to facilitate a graphically supported data collection as well as an easy visualisation of the measurement results. In order to ensure compatibility with the current way of working, the content of the data model is strictly confined to the requirements of the measurement process. Appropriate data interfaces to classification software will enable rapid assessment by the classification societies, thus improving the process in terms of time and cost savings. In particular, decision-making can be done while the ship is still in the dock for maintenance.

Purpose: It is crucial that 119 emergency medical technician (EMT) have adequate knowledge regarding forensic science. This study aimed to assess the forensic knowledge of EMTs in the Republic of Korea. Methods: This study was conducted on EMTs of five fire stations in D metropolitan city between August 6 and August 13, 2018. A questionnaire consisting of items on crime-related incident recognition (i.e., mechanical asphyxiation, trauma, sex crimes, and child abuse), forensic evidence management (i.e., evidence collection, preservation, and recording) was administered to the participants. Finally, 119 questionnaires were analyzed. Results: The ratio of correct answers for crime-related incidents recognition was 55.82%, which was lower than that for forensic evidence management(84.5%). In particular, the scores for the type of neck compression(16.5%) and wound assessment(44.0%) were low. The percentage of correct answers for forensic evidence management was 78.4% for evidence collection, 84.4% for evidence preservation, and 90.6% for evidence recording. Previous forensic education experience was not a significant variable. Conclusion: Specific and practical forensic science education on perception of crime-related incident, including asphyxia and wound identification, and forensic evidence collection is needed.

In previous studies, a system was developed for classifying items of uninsured cost and for generating factors and formulas by item for calculating accident loss costs. However, the loss cost of stopped production was not considered when the system was being developed. In addition, the system which was developed in previous studies had problems such as input error and data collection, owing to numerous input items. Therefore, this study developed a Revised system which considers the loss cost of stopped production, and a Simple system for improving the problems in input errors and data collection. In this study, unquantifiable factors were not considered. Further study that takes these factors into consideration is necessary.

Rapid population growth and land use changes have severely degraded streams across the United States. In response, there has been a surge in the number of stream restoration projects, including stream restoration for mitigation purposes. Currently, most projects do not include evaluation and monitoring, which are critical in the success of stream restoration projects. The goal of this study is to review the current status of assessment methodologies and restoration approaches for streams in Virginia, with the aim of assisting the restoration community in making sound decisions. As part of the study, stream restoration projects data from a project in Fairfax County, Virginia was assessed. This review revealed that the stream assessment methodologies currently applied to restoration are visuallybased and do not include biological data collection and/or a method to incorporate watershed information. It was found from the case study that out of the twenty nine restoration projects that had occurred between 1995 and 2003 in Fairfax County, nineteen projects reported bank stabilization as a goal or the only goal, indicating an emphasis on a single physical component rather than on the overall ecological integrity of streams. It also turned out that only seven projects conducted any level of monitoring as part of the restoration, confirming the lack of evaluation and monitoring. However, Fairfax County has recently improved its stream restoration practices by developing and incorporating watershed management plans. This now provides one of the better cases that might be looked upon by stakeholders when planning future stream restoration projects.

Whilst Ecological momentary assessment (EMA) can provide important insights over time and across contexts among rotation workers whose work periods alternate with leave at home, it can also be challenging to implement in the resources and construction sectors. This review aimed to provide a summary of the methodological characteristics of EMA studies assessing health outcomes and related behaviors in rotation workers. Systematic searches in PubMed, Medline, EMBASE, CINAHL, PsycINFO, and Scopus were done to include 23 studies using EMA methods in assessing health-related outcomes and behaviors. EMA designs included daily diary: assessments once per day typically fixed at the end of day (47.8%), within day fixed interval time-based design: assessments on multiple times per day at certain times of day (17.4%) and combination of both designs (34.8%). Studies employed paper and pencil diaries (73.9%) and one or more electronic methods (60.9%): wrist-worn actigraphy device (52.2%) and online-based diaries (26.1%) for data collection. Most of the studies (91.3%) did not report prompting -EMAs by schedule alerts or compliance. Daily diary and within day fixed interval dairies designs are common, with the increasing use of electronic EMA delivery techniques. It is unclear how well participants adhere to assessment schedules, as these are inadequately reported. Researchers should report compliance-related information.
