As construction projects become larger, process plans become more complex, and inadequate process management leads to waste of time and resources. Effective process management requires process management techniques that can identify problems inherent in the process, continuously improve, and reflect interdependent process characteristics. In the field, the day's details by work type and work status are to be entered in the work daily report. However, even when important information is written, it is not directly linked to the overall process management. This study aims to propose specific process management and decision-making plan based on actual worker by visualizing and quantifying the information described in the existing work daily report. It is expected efficient process management to increase reliability and productivity through process management, which can increase the utilization of work daily reports and facilitates organic communication among participants.

Apartments construction is a one of largest parts in buildings construction. In apartments construction, work interferences are frequently occurred in work processing because workspaces are very various and numerous. However, though work process is important for mainly influencing to the schedule, quality and cost of apartments construction, these work interferences are considered a kind of uncertainty, which is difficult to anticipate at construction planning stage, in work processing. Therefore, this study proposed the measures for work interference reduction in apartment buildings construction and the actual planning for practices. The results can be summarized as follows: (1) the standard of work process is checked regularly. (2) The scope of work and work process is adjusted. (3) The standard of drawings process and cost about work interferences work profess is established.

Objective: This study aims to draw the characteristics of occupational accidents occurred in cabling work, and assess accident severity based on occupational injury data. Background: Accident factors and accident risk are different by the place of work in cabling work. Field managers require information on accident prevention that can be easily understood by workers. However, there has been a lack of studies that focus on cabling work in Korea. Method: This study classifies 450 injured persons caused in cabling work by process, and analyzes the characteristics of occupational injuries from the aspects of age, work experience and accident type. This study also analyzes accident frequency and severity of injury. Results: Results show that preparing/finishing (33.3%) was the most common type of cabling process in injuries, followed by maintenance (28.4%), routing/income (23.1%) and wiring/installation (15.1%) process. The critical incidents in the level of risk management were falls from height in the routing/incoming process, and falls from height in the maintenance process. And, incidents ranked as 'High' level of risk management were slips and trips, fall from height and vehicle incident in the preparing/finishing process, and fall from height in the wiring/installation process. Conclusion and Application: The relative frequency of accident and its severity by working process serve as important information for accident prevention, and are critical for determining priorities in preventive measures.

In consideration of the injuries and deaths occurring at manufacturing sites due to the use of inappropriate work clothes or safety devices, this study aims to categorize manufacturing work processes to develop functional work clothes for heavy industries including the automobile, machine and shipbuilding industries in South Korea. Defining the features of the work environments and work postures of these industries provided for a categorization of the work processes which would enable the development of suitable work clothes for each work process' category. The results of the study based on a questionnaire survey are as follows: Work process category 1, including steel panel pressing and auto body assembly, final inspection (in automobile) and inspection (in machine), requires work clothes with upper body and arm mobility and performance to protect from the toxic fume factor. Work process category 2, consisting of welding (in automobile), cutting-and-forming (in machine) and attachment-and-construction (in shipbuilding), requires clothing elasticity, durability and heat and fire resistance. Work process category 3 comprising welding and grinding in the machine and shipbuilding industries, requires work clothes' tear resistance and elasticity, particularly for lateral bending mobility, and work clothes' sleeves' and pants' hemlines with sealed designs to defend against iron filing penetration, as well as incombustible and heat-resistant material performance. Finally, work process category 4, including painting in machine and shipbuilding, requires work clothes with waterproofing, air permeability, thermal performance, elasticity, durability and abrasion resistance.

Awkward work postures in workshop highly affect on work-related musculoskeletal disorders(WMSDs). Especially, in automobiles assembly process, these awkward work postures of workers may cause serious injury and illness. This study is to compare the performance among the evaluation tools which can measure the work-loads caused by the awkward work postures in automobiles assemble process. RULA, REBA and TVAL(Toyota Verification of Assembly Line) are used as the evaluation tools. The 85 jobs selected in the automobiles assembly process are applied to the three tools and their performances are analyzed after the evaluation of the work-load in each job. Through various measures of performance such as statistical test, DUNCAN test, regression test etc., the tendencies and characteristics among them are analyzed in detail.

건설프로젝트에서 현재 사용되고 있는 작업분류체계(Work Breakdown Structure)는 프로세스 내의 세부작업간 선·후행 관계의 불확실성과 작업의 불합리한 상호 연계성에 기인한 문제점을 내포하고 있다. 이를 해결하기 위해서 본 논문에서는 Work Structuring을 제시하여 프로세스간에 투명성을 부여하고 세부작업간의 간섭을 제거시켜 작업신뢰성을 향상할 수 있는 방안을 도출하였고 프로세스를 개선하기 위한 프로세스 디자인 다이어그램을 개발하였다. WS에 의한 프로세스 개선의 목적은 고객에게 가치를 창출시켜주면서 보다 신속하고 신뢰성 있는 작업 흐름을 만드는 것을 목적으로 하고 있으며 비가치 창출작업의 감소, 프로세스의 명료화 및 투명성 향상 등에 의의가 있다.

According to the trend of tail building, it is essential to improve productivity in tall building construction. However, the study on that is insufficient until now. Therefore, the purpose of this study is to propose a new work process of efficient concrete structural fame work to improve productivity in tall building construction. The results of being applied proposed work process are that the 5day cycle time of concrete structural frame work is cut by 0.5day and the quantity of rebar to be demanded in concrete structural frame work is reduced.

We consider a FIFO single-server queueing model in which both the arrival and service processes are modulated by the amount of work in the system. The arrival process is a non-homogeneous Poisson process(NHPP) modulated by work, that is, with an intensity that depends on the work in the system. Each customer brings a job consisting of an exponentially distributed amount of work to be processed. The server processes the work at various service rates which also depend on the work in the system. Under the stability conditions obtained by Browne and Sigman(1992) we derive the exact stationary distribution of the work W(t) and the first exit probability that the work level b is exceeded before the work level a is reached, starting from x$\in$[a, b].

본 연구에서는 작업 신뢰도 향상의 한 방안으로 기존 공정 관리 기법 상의 한계점을 분석하여 이를 보완하고자 하였다. 그 결과로써 린 생산 원리를 적용한 건설 생산 공정 개선 모델인 CPAM(Construction Process Analysis Model)을 제시하였다. CPAM의 변이 관리 기법을 통해 작업 변이를 최소화시켜 공정계획의 신뢰도 향상 및 생산 효율을 증대시킬 수 있도록 하였고 CPAM에서 제시된 세부작업 일정 계획과 주간작업계획을 통해 건설 현장의 작업 흐름에서 나타날 수 있는 자재, 장비, 인력등의 재고(Inventory or Work In Process, WIP)를 감소시킬 수 있도록 하였다. 또한 본 연구는 건설 생산을 작업 흐름의 관점으로 분석함으로써 기존의 분석에서 놓치기 쉬운 작업 흐름상에서의 불확실성을 최소화시키고 작업 처리량을 최대화시킬 수 있는 대안을 제시하는 데 그 의의가 있다.

e-Learning콘텐츠는 여러 가지 데이터들로 조합된 멀티미디어 데이터로 구성되며, 일정 기간 동안 전문가들이 모여 복잡한 절차를 거쳐 개발하게 된다. 따라서 e-Learning 콘텐츠를 개발하기 위해서는 교육과정의 기획자, 내용전문가, 교수설계자, 나레이터, 웹 디자이너, 웹 프로그래머, 플래셔, 일러스트레이터 등 다양한 작업 그룹 구성원들과 함께 협력작업이 이루어져야 한다. e-Learning콘텐츠 개발에서 중요한 것은 협력작업을 통한 최종 결과물 뿐만 아니라 참여자의 전문성 개발을 통한 품질확보이다. 이러한 전문성은 개념적 기술적 지식의 체계적 축적만으로 개발되는 것이 아니라 진행되고 있는 활동과정과 결과에 대해 지속적으로 숙고하는 과정을 통해 만들어진다. 따라서 참여자들의 전문성 개발을 통해 e-Learning 콘텐츠의 질적 향상을 도모하기 위해서는 공동작업의 진행과정을 모니터링하고 평가함으로써 결과물이 지속적으로 발전할 수 있도록 지원할 필요가 있다. 본 논문에서는 e-Learning콘텐츠 개발 프로젝트 수행에서 중요한 협력작업과 함께 참여자의 전문성 개발은 물론 e-Learning콘텐츠의 질적 향상을 위해 콘텐츠 개발 관련 당사자의 성찰적 학습과정을 지원하기 위한 성찰적 협력작업시스템을 제시하였다. 본 논문에서 제안한 시스템은 크게 업무 프로세스 지원, 개인작업과 협력작업 지원, 협력적 성찰 지원의 네 가지 지원 도구로 구성되어 있다.
