A variety of educational policies have been implemented to educate outstanding individuals who will lead the future and to adopt supporting systems. For the successful implementation of educational policies, it is crucial to identify the perception of teachers as main agents of education. This study conducted a survey with elementary teachers in Chungcheongbuk-do. The purpose of this study was to investigate teachers' perception on the major policies related to ICT(i.e., STEAM, Smart Education, Software Education, e-textbook, and EdudataSystem). This study also compared the distribution of teachers' perception on the policies. The results of the study indicated that teachers had relatively positive perception on the importance and the necessity of the policies. On the other hand, it was found that the levels of teachers' training experiences and readiness for teaching related to ICT were relatively low. In addition, the patterns of teachers' perception on STEAM, Smart Education and Software Education were similar. Based on the results, the study suggested that appropriate support and educational strategies for effective implementation of policies should be established.

Medical oversight (MO) means the advice and direction provided by a physician to rescue workers who provide medical care or carry patients at the scene of an emergency. The purpose of this study was to investigate the utilization of MO and related factors among some 119 rescue workers in Gwangju. A self-reported questionnaire was completed by 153 rescue workers in these 119 safety centers. The data were analyzed by SAS version 9.3. Overall 82.4% of the subjects utilized MO during the past month. In the multiple logistic regression analysis, the married subjects (OR = 3.87, 95% CI = 1.22~12.27), level 1 emergency medical technicians (OR = 2.87, 95% CI = 1.02~8.09), and subjects who treated cardiovascular emergency patients (OR = 9.19, 95% CI = 1.87~45.08) had significantly higher odds ratios for the utilization of MO. The experience of MO accounted for 82%. The development of strategies and education plans taking these results into consideration will help to improve the utilization of MO.

최근 산업안전/보건분야에서 누적외상성질환(Cumulative Trauma Disorders： CTDs)과 직업성요통(Low Back Injury)과 같은 근골격계질환은 산업현장에서 어렵지 않게 발견할 수 있는 신종 산업재해의 일종이다. 특히 미국의 경우, 발생건수와 그로 인한 인적/물적 손실이 급격하게 증가되고 있는 것으로 나타나고 있다. 그러나 미국과 같이 근골격계질환의 폐해를 일찌감치 인식하고 그 해결방안을 연구해온 나라들에서는 현재 환자관리 및 인간공학적인 기준 등을 포함하는 예방지침들이 잘 정착되어 있는 실정이다. 우리나라의 경우에는 작업환경 등의 조건과 상황이 미국과 같은 구미 선전국과 비숫하고, 특히 제조업의 생산체계가 그런 나라들과 매우 유사하여 근골격계질환의 발생과 그로 인한 인적/물적 손실이 적지 않을 것이라고 예상할 수 있지만 아직까지 CTDs에 대한 전반적인 이해가 부족하고, 정확한 실태가 파악되지 못하였으며, 따라서 체계적인 관리 대책 또한 마련되어있지 않은 실정이다. 본 조사에서는 서울 근교의 수송기계관련 사업장의 작업들에 대한 작업자세에 중심을 둔 인간공학평가를 통하여 조사 작업의 근골격계질환에 대한 상대적인 위험도, 위험요인 등을 파악하고, 그에 따른 개선 대책의 방향을 제시하고자 하였다. 특히, 각 부위별 위험점수와 부위별 증상호소율의 상환분석결과, 작업자 개인적 수준에서는 통계적으로 유의한 차는 없는 것으로 분석되었으나, 부서별로 분석한 결과, 작업시 주로 사용하는 오른쪽 상지의 경우, 오른쪽 어깨, 팔꿈치, 손목 순으로 통계적으로 유의하게 관련이 있는 것으로 나타났다. 즉 증상호소율과 해당 신체부위의 위험도 점수는 서로 정적(positive)한 관계에 있는 것으로 나타났고, 상지 중 주로 사용하는 오른쪽 부담의 위험도 자세 점수와 증상호소는 비교적 높은 상관관계에 있는 것으로 나타났다. 따라서 이와 같은 인간공학적 분석결과는 향후 인간공학적인 개선대책의 개발 뿐만 아니라 의학쪽에서 근골격계질환을 접근하는 초기단계에서 매우 유용한 역할을 할 수 있으리라 생각된다.

Due to a shortage of professional labor and the stagnant construction industry in recent days, there has been an increasing demand for securing profitability through cost reduction. Though its importance in the cost and its great influence on the safety and durability of structures, the labor intensiveness of rebar work has caused a serious problem of rising cost accompanied by the loss of rebar materials. In the plant manufacturing process, rebar is cut and bent at the automated facilities and conveyed to the construction site, which makes it possible to manufacture higher-quality bars and to reduce the losses from rebar materials. Different from the expectation, however, this type of plant manufacturing still has not been active since its first introduction in 1990s. In this study, a research on the actual condition of rebar manufacturing plant has been implemented and a standardized rebar manufacturing has been provided as a way to activate rebar manufacturing.

According to the Integrated Notice on City Gas Safety Management Standards, materials for bedding and foundation which are around the pipe should be sands or fine grade soil without large particle that is more than 19 mm size. However, sands are mostly used at gas pipeline construction sites and this causes a shortage of sands and an increase of construction costs. It even causes the disruption of natural environment. In order to improve the standards of backfill material, we have researched regulations in other countries and investigated the pipeline construction sites to survey the present state of backfilling. We also have studied what the bedding and foundation materials affect on buried gas pipelines. Lastly, we have suggested suitable materials for bedding and foundation besides sands. We are sure this paper help the government amend the Notice about backfill materials.

In the digital society where ICT technology is highly developed, digital literacy is an essential competence for working and living. Developed countries around the world have been working hard to solve the digital divide and improve digital literacy. In this paper, we investigated and analyzed the case of US public libraries for improvement of digital literacy of adults including the older people. To do this, we analyzed the educational program type of digital literacy, education method, and the contents of the program, focusing on the best practices libraries of the program. Many of the educational programs still related to basic computer and Internet technologies, and training programs on Micro Office, e-mail, social media, and smartphone and tablet computing were also high. The most frequent and daily training method was informal point of use, and the content and level of education appeared to be very diverse. For digital literacy training, the librarians of the public library considered librarians' digital competence and retraining to be the most important, and the library facility and the latest equipment to be suitable for the operation of the digital literacy education program.

The police substation includes work spaces for civil services, interviews, and meetings, etc, and private spaces for rest, showers and cafeterias and so on. Since a large number of rooms for each function should be installed in a relatively small building, it is important to develop an area standard for efficient space organization in consideration of the functional characteristics and usage patterns of each space. The purpose of this study is to suggest the way for improving the area standards for spaces in police substation based on the results of existing standards analysis and case study. For this objective, architectural documents of 161 police substations built after 2013 in Korea were comparatively analyzed. Sixteen of these facilities were selected for field survey and investigated how the workspace and private area were organized and used. The results of investigation showed that there were a number of problematic cases, such as spaces not installed or insufficient, spaces used for two or more functions, spaces installed even though they are not included in the standards. It was mainly due to the fact that several important spaces which had been installed in most police substations were not included in the existing standards. The ways for improvement were suggested like following four points: (1) Modifying the criteria for classifying facility size, (2) Modifying the lists of the required spaces, (3) Specifying the basis of calculation for each space in detail, and (4) Differentiating the way to organize spaces according to the facility size.

전 세계적으로 중요한 담수 자원인 지하수의 미세플라스틱 오염에 대한 우려가 커지고 있다. 지하수 환경에서 미세플라스틱의 오염을 예측하고 평가하기 위해 대수층 내 현장 실태조사가 수행 중에 있으며, 실험실 규모의 컬럼 실험을 통해 지하수에서 미세플라스틱 이동 메커니즘을 조사하는 연구들이 수행되고 있다. 이러한 연구들은 많은 개수의 분석 시료를 동반하며, 환경 중 미세플라스틱 정량분석을 위해서 고가의 분석기기(라만분광기, 푸리에 변환 적외선(FTIR) 분광기, 열분해 가스크로마토그래피 질량분석기)를 사용하여 플라스틱의 종류를 판별하고 개수를 측정하고 있다. 또한, 컬럼 실험을 수행한 대부분의 선행 연구에서는 미세플라스틱 정량분석을 위해 탁도 분석, 분광광도계를 이용한 흡광도 분석, 현미경을 이용한 계수 방법 등을 이용하여 고가의 분석기기를 사용하지 않고 연구를 수행하였다. 하지만, 이러한 방법들은 유체 속 다른 물질이 포함되어있을 경우에 민감하고 농도를 비율 혹은 개수로 표현하기 때문에 질량 측면에서 미세플라스틱의 농도를 과소·과대 평가할 수 있다. 특히, 현미경을 이용한 계수 방법의 경우에는 분석에 많은 시간이 소요된다는 단점이 있다. 위에 언급한 다양한 분석법들의 단점들을 보완하기 위하여, 본 연구에서는 대수층 내 미세플라스틱 이동 특성을 규명하기 위한 실내 실험에 사용될 수 있는 형광이미지 기반의 미세플라스틱 정량분석법을 개발하였다. Nile Red 형광염료를 이용하여 미세플라스틱을 염색하고 사진을 촬영하여 미세플라스틱 시료의 질량과 미세플라스틱 형광이미지의 형광강도 간 상관관계를 분석하였다. 또한, Nile Red로 염색된 미세플라스틱 입자의 수중 노출 테스트를 진행하여, 실내 대수층 모의실험 시 미세플라스틱 질량을 정량화할 수 있는 적용 가능성을 평가하였다. 상관 분석 결과, 미세플라스틱 질량과 이미지의 형광강도는 높은 상관관계를 보였으며, 수중 노출 실험 전과 후의 미세플라스틱 입자의 형광강도 차이는 미미한 것으로 나타났다. 이러한 연구결과를 통해 본 연구에서 개발된 미세플라스틱 정량분석 방법이 포화 다공성 매체로 구성된 컬럼실험 시 유출수의 미세플라스틱 질량 추정에 유용하게 사용될 것으로 생각되며, 대수층 내 미세플라스틱의 이동 특성 규명 연구에 많은 도움이 될 것으로 기대된다.
