Safety accidents, which are called industrial accidents in construction work, are often caused by unstable physical and personal conditions combined during preparation and execution of work. It is difficult to manage all the construction works, but especially in the field of apartment construction work, complex and many kinds of works are being carried out at the same time. In the current construction, safety regulations such as safety management guidelines are generally well maintained, but the execution of manpower resources that can fulfill them is limited, and it is difficult to reduce the accident rate and loss cost. Therefore, in this study, it is a reality that most of the types of construction work are under contruction by subcontracting contract, so they are limit by methods of manual maintenance and safety education. Currently, the subcontractor is also allowed to perform safety management through the composition of the safety management review body, but it is operated formally. So alternatives to this were studied. As a result, safety accidents occur in the subcontractor's worker due to vertical integration, which is characteristic of the construction industry, together to the contractor, the safety management system is based on a safety construction system in which a worker who has a certain qualification condition such as career experience of the work type, work understanding of the work type, and management experience of the work type among the subcontractor, when we manage based on mutual personality which is the personality of interpersonal relationship that can communicate with each other by work type, process and grouping, it is concluded that effective and practical safety management can be achieved to reduce the accident rate and loss cost.

Purpose: The purpose of the study was to investigate the effects of infection control knowledge and nursing work environment on infection control performance among general hospital nurses. Methods: A total of 138 nurses from four general hospitals located in G and P cities participated in this descriptive study. The collected data were analyzed using t-test, ANOVA, Pearson's correlation coefficients, and multiple regression. Results: The average mean score was 21.41±1.92 points out of 25 for infection control knowledge, 2.53±0.33 points out of 4 for nursing work environment, and 4.62±0.40 points out of 5 for infection control performance. In the final analysis, the variables that had the greatest influence on infection control performance were the nursing work environment (β=.32, p<.001), working department (β=.19, p=.014), and knowledge (β=.19, p=.016). Conclusion: This study showed that nurses with a better nursing work environment, employment in general department, and more infection control knowledge delivered superior infection control performance. Therefore, to improve infection control performance, it is necessary to enhance the nursing environment and develop practical education programs for augmenting infection control knowledge.

This paper formalizes a special type of social networking knowledge, which is called "workflow performer-role affiliation networking knowledge." A workflow model specifies execution sequences of the associated activities and their affiliated relationships with roles, performers, invoked-applications, and relevant data. In Particular, these affiliated relationships exhibit a stream of organizational work-sharing knowledge and utilize business process intelligence to explore resources allotting and planning knowledge concealed in the corresponding workflow model. In this paper, we particularly focus on the performer-role affiliation relationships and their implications as organizational and business process intelligence in workflow-driven organizations. We elaborate a series of theoretical formalisms and practical implementation for modeling, discovering, and visualizing workflow performer-role affiliation networking knowledge, and practical details as workflow performer-role affiliation knowledge representation, discovery, and visualization techniques. These theoretical concepts and practical algorithms are based upon information control net methodology for formally describing workflow models, and the affiliated knowledge eventually represents the various degrees of involvements and participations between a group of performers and a group of roles in a corresponding workflow model. Finally, we summarily describe the implications of the proposed affiliation networking knowledge as business process intelligence, and how worthwhile it is in discovering and visualizing the knowledge in workflow-driven organizations and enterprises that produce massively parallel interactions and large-scaled operational data collections through deploying and enacting massively parallel and large-scale workflow models.

가구디자인의 분야는 다른 제품디자인 분야와 다르게 순수 디자인영역과 함께 스튜디오작업을 병행하는 경우가 많다. 이러한 경우는 대량 생산하는 산업가구보다는 다품종 소량생산이나 맞춤형 주문가구, 혹은 부가가치를 극대화한 작품가구 등을 들 수 있으며, 이러한 작업은 주로 소규모의 공방에서 이루어진다. 이와 같은 소규모 가구 스튜디오에서의 디자인과 제작은 대량생산에 비해 형태와 조형성애서 비교적 자유로울 수 있으며 그에 대한 대표적 조형의 요소는 '곡선'이라고 볼 수 있다. 나무는 그 재료적 특성 상 원목의 곡선 카빙을 제외한 자유로운 곡선의 조형이 까다롭기 때문에 특별한 벤딩기법을 적용해야하는데 이를 위해서 본 연구에서는 베큠프레스의 벤딩기법의 효용성과 가능성을 연구하였다. 베큠프레스의 특징과 다양한 기능분석 및 이를 바탕으로 한 기법개발과 실험을 통해서, 특히 가구디자이너를 위한 소규모 스튜디오에서의 베큠프레스의 효율성과 생산성의 가치를 파악하고 보다 효과적인 벤딩의 작업성을 위해 적절한 충족조건 등을 찾아내고자 하였다.

본 연구는 대학연계형 일학습병행제도 하에서 경영학 이론교육의 방향성을 제안하고자 한다. 사회과학으로서 경영학 교육은 본질적으로 기술습득 중심의 교육보다는 사회현상(기업경영의 현실) 속에서 올바른 의사결정을 할 수 있는 인재를 양성하는데 있다. 동시에 일학습병행제도는 현장직무를 온전히 수행하는데 도움이 되는 인재를 양성하는데 그 목적이 있다. 따라서 실무중심의 교육과 이론 중심의 교육은 유기적으로 연계되어야 하고, 그 이론 교육은 계층화되어야 한다. 또한 경영학 교육은 시의성이 보장되고 융합적 사고를 배양해야 한다. 이러한 배경을 바탕으로 본 연구는 현재 일학습병행제 틀에서 운영되고 있는 국내 대학의 경영학과의 교육과정을 검토하고 발전방향을 제시함으로써 향후 동 제도와 교육수준을 한 단계 업그레이드 시키는데 기여할 것으로 기대된다.

Objective: The aim of this study is to develop a farming shovel to reduce workload, which helps farmers lower the risk of musculoskeletal disease. Background: Most of work using farming tools including shovels requires repetitive works and awkward postures on body parts, and it could possibly cause work-related musculoskeletal disorders. It is necessary to develop and distribute farm equipment and tools in order to reduce physical workload. Method: To improve the most uncomfortable task perceived by ten farmers during the work with a shovel, the improved shovel was designed and made as a prototype for experiment for the comparison of the existing and improved shovels. Twenty males were recruited for this experiment, and muscle activity (%MVC) of six body parts and subjective discomfort ratings by body parts while working with a shovel were measured. A paired t-test was performed to compare physical workload between the existing shovel and the developed one. Results: A shovel applying foothold tied between shaft and blade was designed, which can help workers reduce repetitive bending of back and pressures for upper limbs while digging soil. According to compared evaluation of the developed shovel and the existing shovel, the developed shovel's %MVCs in all experimental muscles were significantly lower than those of the existing shovel. The developed shovel showed the biggest drop in perceived subjective discomfort rating of back, followed by arm and neck, compared to the existing shovel. Conclusion: It was confirmed that attaching a foothold to a shovel was an effective way of reducing workload in back and upper limbs during digging. Application: In the near future, if we put the prototype of developed shovel to practical use after making up for defects, it will help farm work environment be healthier and safer.

The dynamic cast operation allows flexibility in the design and use of data management facilities in object-oriented programs. Dynamic cast has an important role in the implementation of the Data Management Services (DMS) of the Mission Data System Project (MDS), the Jet Propulsion Laboratory's experimental work for providing a state-based and goal-oriented unified architecture for testing and development of mission software. DMS is responsible for the storage and transport of control and scientific data in a remote autonomous spacecraft. Like similar operators in other languages, the C++ dynamic cast operator does not provide the timing guarantees needed for hard real-time embedded systems. In a recent study, Gibbs and Stroustrup (G&S) devised a dynamic cast implementation strategy that guarantees fast constant-time performance. This paper presents the definition and application of a cosimulation framework to formally verify and evaluate the G&S fast dynamic casting scheme and its applicability in the Mission Data System DMS application. We describe the systematic process of model-based simulation and analysis that has led to performance improvement of the G&S algorithm's heuristics by about a factor of 2. In this work we introduce and apply a library for extracting semantic information from C++ source code that helps us deliver a practical and verifiable implementation of the fast dynamic casting algorithm.
