  • Through quantitative analysis of two math classroom videos, combined with the relationship between types of teachers' questioning and students' answering, it is concluded the following problems are in the mathematics classroom teaching: (1) The time of teachers' questioning is longer, the number is too much, with managerial questions and prompting questions is given priority to; (2) Teachers' questioning time is longer than students' answering time, comprehensive answer is more, creative answer is little; (3) In the classroom questioning, students' participation is low; and (4) There is a significant correlation between types of teachers' questioning and length of waiting time after questions. In response to these phenomena, we propose strategies as follows: pursuit of timeliness of classroom questioning, reducing inefficient questions, to increase efficient questions, adopting different waiting strategies for different questioning types, to mobilize students' thinking activities, and improving students' participation etc.

  • In order to improve stability of rail and ride comfort, railway bridges should be maintained a integrity. However, it is necessary to plan various reinforcements and improvements because of a long term used and external effects. In this paper, the improvement plan which is reflected by investigation for reinforcement and improvement is introduced. The constituents of the structures are defined in order to optimize the improvement plane, and the analysis for relationships between the constituents are performed by several evaluation. Finally, the improvement plan is applied to a structure using impact factors for the external effects in order to obtain the improvements reasonably.

  • Since most Green House Gases (GHGs) and air pollutants are generated from the same sources, it will be cost-effective to develop a GHGs reduction plan in combination with simultaneous removal of air pollutants. However, effects on air pollutants reduction according to implementing any GHG abatement plans have been rarely studied. Reflecting simultaneous removal of air pollutants along with the GHGs emission reduction, this study investigated relative cost effectiveness among GHGs reduction action plans in Busan Metropolitan City. We employed the Data Envelopment Analysis (DEA), a methodology that evaluates relative efficiency of decision-making units (DMUs) producing multiple outputs with multiple inputs, for the investigation. Assigning each GHGs reduction action plan to a DMU, implementation cost of each GHGs reduction action plan to an input, and reduction potential of GHGs and air pollutants by each GHGs reduction action plan to an output, we calculated efficiency scores for each GHGs reduction action plan. When the simultaneous removal of air pollutants with the GHGs reduction were considered, green house supply-insulation improvement and intelligent transportation system (ITS) projects had high efficiency scores for cost-positive action plans. For cost-negative action plans, green start network formation and running, and daily car use control program had high efficiency scores. When only the GHGs reduction was considered, project priority orders based on efficiency scores were somewhat different from those when both the removal of air pollutants and GHGs reduction were considered at the same time. The expected action plan priority difference is attributed to great difference of air pollutants reduction potential according to types of energy sources to be reduced.

  • Objectives : We conducted a survey aimed at developing a personal health record application for the treatment of atopic dermatitis in Korean medicine .Methods : We conducted a survey on Korean medicine doctors who attended the Korean Medicine Ophthalmology and Otolaryngology and Dermatology conference 2016. The questionnaire was based on priority of usage of the diagnostic indices and tools, and intention to use the personal health record application for treatment of atopic dermatitis in the clinic.Results : Data were collected from 50 Korean medicine doctors. Ninety-six per cent of respondents replied that they were willing to use the personal health record application for treating atopic dermatitis. Among the diagnostic indices related to atopic dermatitis, Korean medicine doctors regarded the following as important in the order of priority, i.e., condition of skin, lifestyle, risk factors, symptoms other than those of skin, past history, family history and medical history, results of tongue, pulse, and abdomen investigation, and constitution. These results did not vary with the purpose of diagnosis, and the results were consistent with those obtained with the intention to use diagnostic. Over 50% of respondents replied that they use immunoglobulin E, scoring atopic dermatitis, and visual analogue scale among the diagnostic tools.Conclusions : Our survey was conducted on clinicians who are the intended users of the personal health record application for the treatment of atopic dermatitis; hence, the results of this study can be helpful for developing a useful personal health record application for atopic dermatitis in the clinic.

  • 해상교통안전진단제도가 해사안전법(구. 해상교통안전법)에 명시(2009. 5. 27)되어 제도적 기반을 구축한 이후 개선을 위한 지속적인 노력은 계속되어 왔으나 아직까지 제도의 고도화를 위한 종합적이고 체계적인 검토가 이루어지지 못하고 있는 실정이다. 이에, 본 연구는 메타평가에 관한 이론을 토대로 설계된 해상교통안전진단제도의 메타평가 분석틀, 즉 'PIP'OU 메타평가 모형'을 적용, 진단활동 전반에 대한 메타평가를 실시하여 현황 및 문제점을 분석하고 개선방안을 제시하였다. 그 결과, 진단 관련자들은 진단활동 자체가 제도의 목적에 부합하고 있으나 운영 측면은 미흡하여 '진단계획' 영역을 중심으로 개선이 필요하고 특히, 관련 이해당사자간 시각차를 최소화 할 수 있는 방안을 함께 고려하여야 하는 것으로 분석되었다. 본 연구는 제도 개선사항의 시급성을 정량화하여 우선순위를 제안함으로써 향후 관련 정책의 체계적인 개선에 활용될 수 있을 것으로 기대한다.

  • Objective: The purpose of this study was to create soil contamination maps using QGIS (Quantum Geographic Information System) and suggest selection methods for soil pollution sources for preferential investigation in a soil contamination survey. Method: Data from soil contamination surveys over five years in Gyeonggi-do Province, South Korea (2013-2017) were used for making soil contamination maps and analyzing the density of survey points. By analyzing points exceeding the concern level of soil contamination, soil pollutant sources for priority management were identified and selection methods for preferred survey points were suggested through a study of the model area. Results: A soil contamination survey was conducted at 1,478 points over five years, with the largest number of surveys conducted in industrial complex and factory areas. Soil contamination maps for copper, zinc, nickel, lead, arsenic, fluoride, and total petroleum hydrocarbons were made, and most of the survey points were found to be below concern level 1 for soil contamination. The density of the survey points is similar to that of densely populated areas and factory areas. The analysis results of points exceeding the criteria showed that soil pollutant sources for priority management were areas where ore and scrap metals were used and stored, traffic-related facilities areas, industrial complex and factory areas, and areas associated with waste and recycling. According to the study of the model area, the preferred survey points were traffic-related facilities with 15 years or more since their construction and factories with a score of 10 or more for soil contamination risk. Conclusion: Soil contamination surveys should use GIS for even regional distribution of survey points and for the effective selection of preferred survey points. This study may be used as guidelines to select points for a soil contamination survey.
