현장이 개설되어 공사가 진행되어지는 중에 발생하는 예상할 수 있는 악재들, 즉 주변민원, 기능인력부족, 자재나 장비 파동, 급격한 기후의 변화(폭설, 폭우 등), 예상보다 긴 장마, 가설물의 붕괴 및 전도 등의 요인들은 그 원인이 현장내부가 아닌 외적인 환경에 의한 것이었고 따라서 단위현장 1개소가 아닌 일정지역에 있는 현장들이 공통으로 겪게되는 일종의 난관이었다. 그러나 현장 내에서 작업 중에 발생하는 사망사고는 일단 현장내 원인으로 발생되고, 타 현장과는 공유할 수 없는 사안이라는 점에서 앞서 밝힌 외적요인들과는 근본적으로 다르다 하겠다.(중략)

현대사회의 산업 현장에서 작업효율과 안전사고예방은 기업의 이익과 직결된다. 현장에서의 인력의 사용으로 인한 한계점을 가지고 있기 때문에 효율적이고 안정적으로 작업 효율을 내며 현장의 많은 안전사고를 미연에 방지하기 위해 많은 산업현장들은 4차 산업 혁명을 통해 수많은 작업들을 로봇을 이용한 자동화로 대체해 오고 있다. 단순히 짐을 옮기고 재고를 파악할 뿐인 간단한 작업임에도 불구하고 물류 피킹/분류 작업은 아직까지 인력을 사용한다. 인력을 한계를 극복하기 위해 작업 현장을 라인 트레이서를 통해 이동하고, 영상분석을 이용해 로봇 암으로 원하는 물건을 정확하게 피킹하고자 적재 하도록 설계한 '영상분석을 이용한 자동 피킹.분류시스템' 기술을 제안한다. 기존의 단순 반복 노동의 피킹/분류 작업을 수행하며 영상분석을 통해 어플리케이션을 이용하여 재고 관리또한 가능하다,

There is a growing interest in Co-operative education as an important way of university-industry collaborations for improving employment competitiveness, recruiting talented human resource, and promoting university-industry collaborations. In this study, we recognize that the paradigm of professional practice have to be changed from internship to Co-operative education. This paper examines the characteristics of Co-operative education in a regional public university through a case study of Central Washington University(CWU), USA. The results of the study and policy implications are as follows. First, the professional practice program of CWU is centered upon Co-operative education and has a high local and regional connectivity in terms of location of institutions that students work for professional practices. Second, the professional practice program of CWU has a high connectivity between majors and jobs, and is characterized by an active participation of students majoring in humanities, social sciences, arts and education. Third, the qualifications of Co-operative education are strict, but programs of Co-operative education are flexibly operated according to the characteristics of departments and colleges. We emphasize that universities in Korea need to focus upon the employment connectivity, the major connectivity, the local and regional connectivity, Therefore, when attempting to introduce Co-operative education. In addition, the management and governance of Co-operative education should be flexible.

Laser induced breakdown spectroscopy (LIBS) is a recently developed analytical technique that is based upon the measurement of emission lines generated by atomic species close to the surface of the sample, thus allowing their chemical detection, identification and quantification. With powerful advantages of LIBS compared to the conventional analytical methodology, this technique can be applied in the detection of heavy metals in the field. LIBS allows the rapid analysis by avoiding laborious chemical steps. LES have already been applied for the determination of element concentration in a wide range of materials in the solid, liquid and gaseous phase with simplicity of the instrument and diversity of the analytical application. These feasibility of rapid multi elemental analysis are appealing proprieties for the in-situ analytical technique in geochemical investigation, exploration and environmental analysis. There remain still some limitations to be solved for LIBS to be applied in soil environment as an in-situ analytical technology. We would like to provide the basic principle related to the plasma formation and laser-induced breakdown of sample materials. In addition, the matrix effect, laser properties and the various factors affecting on the analytical signal of LIBS was dealt with to enhance understanding of LIBS through literature review. Ultimately, it was investigated the feasibility of LIBS application in soil environment monitoring by considering the basic idea to enhance the data quality of LIBS including the calibration method for the various effects on the analytical signal of LIBS.

The field organization management in construction industry is very important factor improvement and cost reduction. But, until now, evaluation methods on the existing field organization did not make ready and endeavor of organization betterment was insufficient in construction industry. The purpose of this study to provide basic data for reasonable selection and evaluation of the field manager through analyzing operation status of the existing field organization in apartment and office building project by interview and questionnaire on the 22 construction companies. This study presented optimal proposal on the selection and evalution of field manager for productivity improvement and cost reduction by means of efficient construction progress in apartment and dffice building project.
