In this study, we carried out an experimental shield TBM excavation model test using a down-scale device in soft clay, to understand tunnel-face stability properties in relation to changes in slurry pressure. We performed five tests according to tunnel depth (0.5D, 0.75D, 1.0D, 1.25D, 1.5D), and compared theoretical tunnel-face pressure with model test results. The range in theoretical tunnel-face slurry pressure ($P_{min}{\leq}P_{slurry\;pressure}{\leq}P_{max}$), which is determined by earth pressure and water level, was very similar to the model test result. This result was due to the more isotropic condition of the soft clay ground, than of rocky ground.

The failure of the road cut-slope due to heavy rains brings about lots of injuries and damage on national properties. KICT has developed CSMS system by means of prevention to manage the dangerous cut slopes. In spite of the continuous management the frequency of cut-slopes failure is increasing the past due to changes of earth-environment. KICT has installed the "Real-Time Monitoring System" on dangerous slopes. The operation of Real-Time Monitoring System is used as a positive system to reduce injuries and damages. However, Although the slope manager is aware of the signs collapsed in advance, it has temporal and spatial limits until the slope manager performs the works which are preventing the accidents. When real time monitoring system finds out an indication of slope collapse, the Rock-fall Signal Lamp System makes road-users indicated the risk of cut slopes. It is a kind of prevention system that it will minimize the damages of the properties as suspension of traffic automatically or passively.

Among public organizations, does variation in organizational structure explain variation in public managers' leadership styles (e.g., transformational and transactional leadership)? The study of leadership in public organizations is increasingly an area of scholarly interest partly sparked by movements to reform public organizations, particularly in the context of emergency management. There is, for example, a need for effective leadership that can help organizations respond to disasters (Kapucu et al. 2010; Van Wart and Kapucu 2011; Stern 2013). There are numerous documented cases where the lack of leadership skills has been linked to major social and economic losses as a result of poor disaster response (e.g., Hurricane Katrina in the U.S.). Yet, leadership is a complex concept and numerous theoretical frameworks have been developed to help explain it (Van Wart 2005). Practically speaking, the existence of different theories of leadership suggests that public managers can decide to exercise various styles of leadership. The style of leadership that a public manager exhibits matters because some styles are perceived to be more effective than others (Trottier et al. 2008). While the effects of leadership have been extensively studied, antecedents or predictors of leadership style have received little scholarly attention (Wright and Pandey 2009; Nielsen and Cleal 2011). The purpose of this research note then is to explore the potential causal relationship between the structure of an organization and the ability of a public manager to exercise transformational leadership in the context of emergency management in two Asian countries: South Korea and Japan. This research note consists of three main sections. The following section explores the relationship between leadership and organizational structure. The second section examines how certain concepts of leadership and organizational structure were applied in two case studies of disaster response. The final section presents some directions for future research.

Food consumption pattern changes, including a decrease in rice consumption and increasing demand for fresh vegetables, along with declining food self-sufficiency rate, more importance is being placed on agricultural industry within Korea. Taking these changes into consideration, there is an increasing necessity for managing upland fields on agricultural sector to revitalize agricultural land use. Therefore, in this study, upland use type was classified into agricultural economic, environmental conservation, and rural social frames. The purpose of this study was to suggest upland use plan with farm manager registration information and spatial data. As results of this analysis, the mean area of agricultural economic frame in Haenam (16.47 ha) was found to be wider than Muan (3.17 ha), and scale improvement zones (54 zones) were located in only Haenam. In case of environmental conservation frame, there's no zone of scenic agriculture land in both study areas, but landuse transition zones were located in Muan (278 zones) and Haenam (604 zones). Agro-healing zones of rural social frame were 1,018 zones in Muan and 1,588 zones in Haenam and kitchen garden sites were 342 zones in Muan and 370 zones in Haenam. These results could be used when we establish the plan of an agricultural infrastructure project or select places for a collaborative agricultural land use project.

The ground excavation in the urban area induces in general ground movement and subsequent damage on the adjacent building structures. So the essentials in the designing stage are the prediction of ground movement induced by the ground excavation and the damage risk assessment of buildings adjacent to the excavation. A propsed prediction method of the ground movement induced by the strutted excavation has been studied with due consideration of the existing ground movement prediction methods. A building damage risk assessment method based on the angular distortion and the horizontal strain derived from the green-field ground movement is also proposed. These methods have been applied successfully in the on-going deep excavation project in Singapore.

The cattle shelters have been badly damaged by the recently large fires. so the reconstruction of the damaged shelter is very difficult. In the light of the seriousness of the fire like that, the preventive plan for the cattle shed should be thoroughly established. The preventive measure which the fire department performs presently is limited to the stopping the fire before it starts. More than anything else, The men who operate and manage the cattle shelters must know what to do. The written plan will assist them. To begin with, The fire authority should clearly specify how cattle should be protected from any outbreak of fire. Clear access to each fire shed is very important to protect the cattle safely. The manager of the cattle shelter should get ready for the fire defense equipment. Most fires of the cattle shelters are due to electricity faults. These renovations should be performed and checked immediately. Therefore, The manager should be ready assist fire chief or the professional organization to prevent the electricity fire. Fire Safety education should be planned for the owner and staff so all should know what is expected in case of a fire. The Fire Department will check the access road, the equipment available and an announced fire drills should take place every year in the cattle shelter. The Fire Department should check the access road, equipment for preventing fires and staff training each year.

In recent years, there has been a demand for a residential supply model that can actively and flexibly cope with various housing demands in the changing paradigm of public rental housing. This study focuses on the two-step supply system that has been studied in Japan. It was used to examine and analyze cases to recommend a supply plan that can be used for domestic public rental housing. In more detail, the literature review of the two-step supply system discloses that four types by supply methods (A-1, A-2, B-2, and C-2) and four types of relationship (construction and management combine entities type, management entity type, construction entity type, a separated entity type) can be categorized. In addition, from the actual case study, it revealed that the way of linking and supplying activities among the entity can have a great influence on "ease of supply (supply)", "diversity of housing demand (diversity)," and "quality of construction (construction)". "Ease of supply (supply)" refers to whether the construction entity is separated, and the owner is a manager. "Diversity" refers to whether the management subject is separated, and if the owner is also the constructor or the manager. "Construction" is whether the management entity is connected and managed by the management entity and can be evaluated in "Good", "Middle", and "Bad" level. As a summary, even if the existing public rental housing in Korea can be separated into a skeleton and infill system, the result suggested that it has a limitation on response to residential demand. In addition, the paper was able to propose an improved plan to make the infill as a secondary operator.
