Although individual-level factors (e.g., attitudes, personality) have long been associated with day-to-day attendance decisions, increasingly researchers have recognized "the social nature of attendance dynamics and their susceptibility to social control (Johns, 2008)." Implications of this social approach for research would be to focus attention on the causes and effects of absence culture (i.e., absence-related perceptions, beliefs, values), and the effects of absence culture on individual and group attendance within social units. Construction projects typically require workers to work in teams or crews on highly interdependent projects, and, thus, are particularly relevant contexts to study absence culture. In this paper we apply a system dynamics (SD) model to study absence culture by utilizing the advantages of SD in capturing a feedback process and state changes. We were particularly interested in: (a) the awareness of social norms within construction crews that pertained to attendance, (b) the interplay between formal attendance rules (policy) and these social norms, and (c) how these sources of influence affected the decision-making process of construction crew members. We expect that the results of this work will help construction organizations evaluate (or re-consider) the effects of their attendance control policies (e.g., timing, strength, and frequency) within a social context. Moreover, our findings suggest that the key to reducing excessive absences might be to invest time in influencing absence culture directly rather than imposing frequent and strict regulations - which, in turn, may inadvertently fortify a culture that works against the organization's interests.

Dutch artist, Theo van Doesburg had shown short but strong experimental aesthetics in his works through De Stijl movement. He played a leading role for editing De Stijl magazine and performed various formative works such as painting, sculpture, and architecture. In 1923 he opened the first De Stijl exhibition cooperated with Cornelis van Eesteren. In this architecture exhibition he showed rich formal spirits of counter-construction in his major design works, that is Maison Particuliere and Maison D'artiste among three houses projects. Formal characteristics of counter-construction can be summed up under two categories, time and space. Analytical results are as follows; First, the characteristics of counter-construction related to time category include two types of two mode. One is linear aspect of time based on the viewer's movement. The other aspect is simultaneity caused by synoptical effect. These could be proved by the analysis of arrangement of color planes. Secondly, the spatial aspects of counter-construction are produced through two different ways of formal strategies. Van Doesburg arranged cubes in very irregular pattern. This treatment induces ambiguous void and creates feeling of subject's space. And, through deleting, shifting, and extending he could make dynamic spatial effect by interpenetration between in and out. This fluid space thus introduces movements of one's gaze and circulation. He denied traditional classical values which had ruled the western aesthetical discipline for centuries and believed that mankind can reach the realm of universal equilibrium by contrast and tension created by counter-construction. In this vein Theo van Doesburg was an avant-garde artist of Hegelian thoughts who adopted the dialectical method without following the formal characteristics from ancestors.

With rapid industrialization, electric power consumption has been increasing every year in Korea and in other countries. The provision of additional power stations to produce more electricity is one possible response to this steady increase in consumption. Another alternative is to improve the efficiency of existing stations through timely and effective maintenance works. Since the construction of a new power plant involves a large amount of capital as well as difficulties in the selection of sites, the improvement of existing power stations' efficiencies is often a preferred solution. Therefore, this paper focuses on maintenance project management to address this issue. Among several types of maintenance works, this paper concentrates on planned outage maintenance (POM). This focus arises from the critical impact of POM on other maintenance work, as well as the entire process of electricity production. Unlike other maintenance work, POM is done on the basis of mid and long-term plans. In addition, only POM works are conducted during the outage of all power plants. To evaluate the efficiency of POM works, budget data relating to 164 POM projects between 2001 and 2008 was collected from 7 sites in South Korea. Data envelopment analysis (DEA) was selected as a methodology for evaluation. From this analysis, comparative study was used to determine the categories of projects that had performed well, and those with the most optimized budget structures. Moreover, through discussion with industry, this research develops a feasible proposed method by which to enhance the efficiency of POM projects.

A well-maintained landscape can increase the competitiveness of a city. Gyeongju which is the famous ancient capital of Korea, has numerous historical resources. However, the disharmony between the historical landscape and the surrounding landscape weakens the competitiveness of the city. At present, most landscape analysis methods mainly focus on plans, photos, and animation, which have certain limitations in the expression of landscape spatial scale and materials. This study aimed to use the virtual walkthrough method to take the Wolseong District of Gyeongju historical areas as the object in order to evaluate the landscape visually. Compared with planar landscape analysis methods, such as photos and videos, the virtual walkthrough method is more immersive and intuitive to experience the spatial scale. The study results revealed images, visual characteristics, and visual influence factors of the landscape, which provide essential data for the construction and improvement of landscapes in similar historical areas in the future.

ERP system has been spreaded from large companies to many small and medium sized companies, and it is recognized as a basic system for optimum and efficient work process. The focus is moving from manufacturing companies to various specialized companies. Once ERP system was introduced to those specialized companies, there was attempt to customize an ordinary system which used in manufacturing companies, but it was hard to take effect due to the lack of experience and an inadequate analysis of work process. Some of foreign ERP packages are possible to be constructed for some companies. However, they are originally aim at a large enterprise and it is also very difficult to construct and maintain. For this reason, small and midium sized companies are having a difficulty to construct ERP system. This study deals with the construction of ERP system for small and medium sized design engineering company and introduction of the crucial points throughout the construction and requirements for composition module and customization of each main module. Based on the findings of this study, the specialized non-manufacturing companies are expected to have efficient and practical application of ERP system when they select and customize the ERP package of manufacturing companies.
