Due to the dense and complicated working environment, the construction industry is susceptible to many accidents. Worker's fall is a severe problem at the construction site, including falling into holes or openings because of the inadequate coverings as per the safety rules. During the construction or demolition of a building, openings and holes are formed in the floors and roofs. Many workers neglect to cover openings for ease of work while being aware of the risks of holes, openings, and gaps at heights. However, there are safety rules for worker safety; the holes and openings must be covered to prevent falls. The safety inspector typically examines it by visiting the construction site, which is time-consuming and requires safety manager efforts. Therefore, this study presented a worker-driven approach (the worker is involved in the reporting process) to facilitate safety managers by developing integrated computer vision and inertia sensors-based mobile applications to identify openings. The TensorFlow framework is used to design Convolutional Neural Network (CNN); the designed CNN is trained on a custom dataset for binary class openings and covered and deployed on an android smartphone. When an application captures an image, the device also extracts the accelerometer values to determine the inclination in parallel with the classification task of the device to predict the final output as floor (openings/ covered), wall (openings/covered), and roof (openings / covered). The proposed worker-driven approach will be extended with other case scenarios at the construction site.

미국 건설산업은 숙련된 기능공의 부족이라는 도전적 과제를 경험해 오고 있다. 이 문제는 다음과 같은 여러 원인들에 의해 야기된것이다. 건설산업의 이미지 저하, 훈련과 교육의 부족, 불분명한 경력관리, 임금의 저하, 노동인력의 구성변화. 건설인력과 관련된 이러한 문제점들을 근본적으로 해결하기 위해 Two-Tier Work Force Strategy라는 획기적인 접근방법이 Center for Construction Industry Studies (CCIS)에서 제안되었다. Two-Tier Work Force Strategy는 Tier I과 Tier II Strategy로 구성되어 있다. Tier I 전략은 기술이 떨어지고 단순작업이 가능한 기능인력을 활용하며, 많은 수의 현장관리인원을 필요로 한다. Tier II 전략은 상대적으로 잘 교육받고, 기술수준이 높은 소수의 기능인력을 활용하며, 그들은 기능능력과 더불어 관리능력도 갖추고 있어야 한다. 그들은 더 높은 급여를 받지만, 높은 기술수준으로 인해 더 생산적으로 일할 수 있고, 다중기술의 보유로 더 오래 현장에머물며, 안전, 품질, 공정, 그리고 원가적 측면에서 향상된 프로젝트 성과를 가져온다. Two-Tier Work Force Strategy는 근래의 기능인력에 대한 문제점을 해결하고, 미래에 더 나은 노동환경을 가져올 수 있는 방안이 될 수 있을 것이다.

This paper reports problems of current working environment on construction site in South Korea from a female laborers' point of view and proposes solutions to improve the environment. To investigate and analyze the problems, a questionnaire survey and a focus group interview were conducted with 341 engineers and 557 laborers. Among them female engineers and female laborers were 51 and 136 respectively. Findings are the facilities related with welfare facilities such as lavatories, shower rooms, lounges and changing room, etc. for women were not sufficient and even not installed only for women because all of the planners for the facilities were men and The Standard of Estimate does not consider gender distinction. The data on the trade and the number of female laborers were not recorded and this study confirmed the number and the proportion of female laborers according to construction progress i.e. the proportion of female laborers were 0% ~ 11% (average 6%) at 26 construction sites having 2% ~ 92 % construction progress. In order to solve these problems, gender education for the welfare facility planner is required and the current Standard of Estimate should be revised considering female laborers after collecting the site data for the number of female laborers according progress and the increase in the construction cost should be reflected in the contract amount accordingly. Conclusively temporary work planning related with welfare facilities should be established and conducted in terms of gender equality at construction sites. In addition, improving working environment on construction sites for female laborers will enhance the company's image and also helping solve the labor shortage problem by women laborers engaging in construction industry easily.

While it is an important element of clothing construction, research has so far been very limited on the similarities between virtual and real clothing in terms of the type of neckline. The purpose of this study is to verify the similarity, accuracy of virtualization, and actuality of neckline, which all play an important role in individual impressions and image formation, and require considerable modification when fitting real samples. A total of 5 neckline models were selected through the analysis of dress composition textbooks. The selected designs were then planned and manufactured in muslin. The specimen clothes were then tested on a female model in her 20s. 2 kinds of virtual bodies were created in order to compare the real and the virtual dressing. The first virtual body was made through an Artec 3D Eva scan of the model, and the other was made by entering the model's measurements in a CLO 3D program. A visual image of the front, side, and back image of both the real and virtual dressing were subsequently collected. The collected images were then evaluated by 20 professional fashion workers who checked the similarity between the real and the virtual versions. The current study found that the similarity between the actual and virtual wearing of the five neckline designs with reality appeared higher with the virtual wearing image using the 3D-scanned body. The results of this study could provide further information on the selection of appropriate avatars to clothing companies that check the fit of clothing by utilizing 3D virtualized programs.

The problem of urban decay in Hong Kong has drawn much attention of both practitioners and academics. Poorly managed buildings not just give a negative image to the Pearl of the Orient in the region, but also pose potential risk hazards to the health and safety of the general public. While it is necessary to devise a comprehensive plan on redevelopment and urban planning, preserving the existing buildings to maintain their conditions for habitation can be a short-term option to safeguard quality standard. With the increasing number of ageing buildings in Hong Kong, a lot of research efforts have been devoted to managing repair and maintenance projects properly (for example those initiated and funded by the Construction Industry Institute, Hong Kong; and the current study financially supported by The Hong Kong Polytechnic University). Given the short duration and more diversified nature of work, building repair and maintenance works are found to be more difficult to monitor and regulate when compared with new works. This paper aims to provide a comprehensive analysis on the problems of running building maintenance projects. An extensive review of contemporary literature was firstly conducted, which forms a solid basis for developing an empirical study on the problems and difficulties of running building maintenance projects from the viewpoints of industrial practitioners with a view to formulating effective strategies for managing maintenance projects successfully.
