지식사회로의 전환과 함께 지식경영의 중요성이 부각되었고 지식의 원천인 인적자원에 대한 관심 또한 증가하였다. 이러한 관심의 결과로 국내 기업들은 '핵심인력확보', '우수인력양성' 등과 같은 인적자원에 대한 투자와 개발을 실시하였고있다. 이러한 인적자원관리 및 투자의 일환으로써 '인재의 적재적소 원칙과 우수인재의 파악 및 핵심인력의 양성' 이라는 목적하에 직원들의 경력관리에 대하여 관심을 갖고 이를 실천하고 있다. 그러나 기업이 만들거나 개발한 경력 관리를 위한 프로그램과 시스템은 개인(직원)이 자사에서 '어떤 직업 훈련을 받았는지, 어느 곳(현장)에서 근무를 하였는지, 어떤 자격증을 갖고 있는지' 등을 관리하는 것에 그치고 있어, 조직원의 능력(know-how, 기술, 업무경험 등)이 수행 프로젝트의 성패를 좌우하고 이러한 능력에 대한 의존성이 타 산업의 프로젝트보다 높은 건설기업의 경우에는 적절하지 않다고 판단된다. 따라서 본 연구에서는 건설기업의 인력관리의 한 요소로 실시되고 경력관리에 대한 문제점의 파악과 건설기업의 경우에 필요한 건설인력을 위한 경력관리에 대하여 논하였다.

This study investigated the effect of horizontal casting joints on the mechanical properties and structural behavior of sustainable self-compacting reinforced concrete beams (SCRCB). The experimental research consisted of two stages. The first stage used four types of concrete mixtures which were produced to indicate the effects of cement replaced with cement waste at 0%, 5%, 10%, and 15% by weight of cement content on fresh concrete properties of self-compacting concrete (SCC) such as, passing ability, filling ability, and segregation resistance. In addition, mechanical properties such as compressive, tensile, and flexural strength were also studied. The second stage selected the best mixture from the first stage and studied the effect of horizontal casting joints on the structural behavior of sustainable SCRCBs. The effect of horizontal casting joints on the mechanical properties and structural behavior were at the 25%, 50%, 75%, and 100% of sample height. Load deflection, failure mode, and theoretical analysis were studied. Results indicated that the incorporation of replacement with cement waste by 5% to 10% led to economic and environmental advantages, and the results were acceptable for fresh and mechanical properties. The results indicated that delaying the time for casting the second layer and increasing the cement waste in concrete mixtures had a great effect on the mechanical properties of SCC. The ultimate load capacity of horizontal casting joints reinforced concrete beams slightly decreased compared with the control beam. The maximum deflection of casting joint beams with 75% of samples height is similar with the control beam. The experimental results of reinforced concrete beams were substantially acceptable with the theoretical results. The failure modes obtained the best forced casting joint on the structural behavior at 50% height of casting in the beam.

Congestion is a growing concern of many global cities and the demands on Infrastructure services within a locale coupled by the rising expectations from the growing population places stress on these cities. This entails the ability to build a sustainable community that requires an understanding and recognition of Population growth, changing demographics and the ever changing urban development on both a macro and micro level. Infrastructure is an integral part of Australian economy, particularly the 'Infrastructure Assets Management' which highlights the importance towards the development of sustainable communities for Melbourne's future. Melbourne 2030 is a comprehensive representation of government's response to a wide-ranging population growth within Melbourne metropolitan and surrounding areas. Urban plan and specific Infrastructure Assets Planning needs not only to provide sufficient Infrastructure to a community, but it must also be efficient and innovative so that it produces an optimised management system. A system that incorporates engineering techniques that will be sustainable for decades to come by maintaining an acceptable level of services to its intended community in an effective manner, which also strengthens service delivery. The fundamental challenges for optimization of Infrastructure with the Melbourne urban plan is, the ability to manage and sustain maintenance of Infrastructure to provide the acceptable level of service required by the community in a most effective manner which also strengthens service delivery to contribute towards Melbourne 2030. This paper particularly investigates some of the fundamental issues within the Melbourne urban plan such as Infrastructure Asset Management, AusLink and the Australian Road Management Act 2004, which the Governments at all levels must deal with to provide an economically viable solution to the changing Infrastructure so it may suits the needs and services the strategies of a metropolis.

Modular building is a fast-growing construction method, mainly due to its ability to drastically reduce the amount of time it takes to construct a building and produce higher-quality buildings at a more consistent rate. However, while modular construction is relatively safer than traditional construction methods, workers are still exposed to hazards that lead to injuries and fatalities, and these hazards could be controlled using emerging smart technologies. Currently, limited information is available at the intersection of modular construction, safety risk, and smart safety technologies. This paper aims to investigate what aspects of modular construction are most dangerous for its workers, highlight specific risks in its processes, and propose ways to utilize smart technologies to mitigate these safety risks. Findings from the archival analysis of accident reports in Occupational Safety and Health Administration (OSHA) Fatality and Catastrophe Investigation Summaries indicate that 114 significant injuries were reported between 2002 and 2021, of which 67 were fatalities. About 72% of fatalities occurred during the installation phase, while 57% were caused by crushing and 85% of crash-related incidents were caused by jack failure/slippage. IoT-enabled wearable sensing devices, computer vision, smart safety harness, and Augment and Virtual Reality were identified as potential solutions for mitigating identified safety risks. The present study contributes to knowledge by identifying important safety trends, critical safety risk factors and proposing practical emerging methods for controlling these risks.

The government has established various policies focusing on accident prevention to reduce the accident rate in the construction industry, but the effect is still insignificant. These results allude that there are still many problems in terms of usability. Although construction safety accidents usually have characteristics that occur during construction, the laws and systems should include the pre-construction cycle (plan/order - design - construction business management- construction) to eliminate risk factors in advance. The purpose of this study is to analyze the performance evaluation of the construction safety system before construction rather than during construction. In the pre-construction phase (plan/ order-design-constuction business management), we intend to investigate and analyze measures to prevent safety accidents and identify a system that lacks the ability to implement. Specifically, we analyzed what to focus on as precautionary measures in the planning, ordering, designing, and supervising. To improve them, we made a questionnaire based on the role related to construction safety for each subject, and seek implications for lack of performance through interviews. Based on the results, some ways to improve the safety system were proposed.

최근 많은 기업들이 개개인의 인적자원을 기업 가치 창출의 핵심 자산으로 인식하고, 기업 경쟁력 강화를 위하여 역량기반의 인적자원관리 및 인재육성에 많은 노력을 기울이고 있다. 국내 건설업에서 큰 비중을 차지하고 있는 종합건설회사의 건설기술자는 건설 프로젝트 생애주기의 각 단계에서 다양한 참여주체와 함께 공사관리 업무를 수행하며, 건설기술자의 역량은 건설공사의 성패에 직접적인 영향을 미치는 중요한 요소이다. 하지만 현재 국내의 건설기술자 능력 평가 방식은 자격 위주의 평가로서 실제 공사관리 업무에 대한 소화능력과는 거리가 있다. 이와 같은 관점에서 본 연구는 건설업의 기본관리 항목 중 하나인 원가관리의 업무 프로세스 및 세부 수행항목을 분석하여 원가관리 업무 숙련도 수준을 제시하였고, 이를 바탕으로 건설기술자 직급별 요구역량 대비 현 수준 분석 및 업무 단계별 건설기술자 업무역량 분석을 실시하여 시사점을 도출하였다.

Purpose: This study investigates dental health and chewing ability of patients hospitalized in geriatric hospital, and compares the chewing ability for each factor that can be used as data for dental healthcare of senior citizens and basic data for denture insurance for the elderly. Methods: The 101 subjects of this study were selected from 178 patients hospitalized in a geriatric hospital located in Daegu Metropolitan City, excluding 77 patients who were being treated in the intensive care unit and who were unable to communicate. The chewing ability of the patients were measured using an evaluation scale based on foods consisting of 10 different hardnesses. Results: Patients with less than 21 teeth, those with dentures and patients who were less than satisfied with their dental conditions had difficulties in chewing hard food such as dried squid and radish kimchi, and the Chewing ability increased proportionally to the number of remaining teeth(p<0.001), appropriateness of the maxillary and mandibular dentures(p<0.005) and the level of dental satisfaction(p<0.001). Conclusion: This study is limited as the subjects were selected from a single hospital and the authors estimate that various studies will be necessary to investigate the Chewing ability of patients hospitalized in long-term hospitals. The subjects of this study did not receive any dental treatment while staying in the hospital and many of the subjects had bad fit denture or didn't have dentures or did not use dentures, although they have dentures, which calls for denture construction and prosthetics through dental treatment.
