Tunnelling has become a preferred method of construction for road and highway projects in countries with a lot of hilly slope geological conditions such as found in Malaysia. However the construction works of a tunnelling project are usually complicated and costly, which consequently impose great risks to the parties involved. This paper identifies the key significant risks and sub-risks for tunnelling construction projects in Malaysia through a case study. Interview has been used as the solitary means to determine the significant risks from contractor's eleven key project personnel who were directly involved in the tunnelling construction such as consultant, construction manager and tunnel engineers. The importance of the risks identified is then prioritised and ranked via the Analytic Hierarchy Process (AHP)'s pairwise comparison approach to determine their criticality towards a successful delivery of project. As a result, three key risks have been identified as significant for the tunnelling case study project, namely health and safety, cost overrun in construction and time overrun in construction. Two sub-risks each of the latter categories, which are cost underestimation and unforeseen events (cost overrun in construction) as well as plant and machinery failure and delay in material delivery (time overrun in construction), have occupied the top five overall risk ranking.

In the marine industry although there has been significant growth towards safety, security and risk assessments or risk-based strategies such as marine insurance and regulations to avoid the risks of damage to properties and the environment or the prospect of premature death caused by accidents etc, the moves toward managing the risks which are linked directly to the business functions and decision making processes have been very slow. Furthermore in the marine industry most perceptions, methodologies and frameworks of dealing with hazards, risks, safety and security issues are for their assessment rather than their management. This trend reveals the fact that in different marine industry sectors such as logistics and shipping there is a lack of coherent risk management framework or methodology from which to understand the risk-based decisions especially for the purpose of design, construction, operation, management and even decommissioning of the marine related applications. On the other hand risk management is not yet viewed holistically in the marine industry in order to, for example, assign a right person, i.e. risk manager, who can act as a coordinator and advisor with responsibilities that are only specific to risk management. As a result this paper, by examining the present physical borders and risk-based activities in the marine industry, aims to propose an appropriate risk management methodology in addition to the emergent role of risk managers which will enable the industry users initially to become familiar with the concept of risk management at its holistic level. In the later stages this eventually can lead to development of risk management capabilities at an exclusive level and its integration into the marine industry functions in future.

For agricultural water management, it is essential to establish the digital infrastructure data such as agricultural watershed, irrigated area and canal network in rural areas. Approximately 70,000 irrigation facilities in agricultural watershed, including reservoirs, pumping and draining stations, weirs, and tube wells have been installed in South Korea to enable the efficient management of agricultural water. The total length of irrigation and drainage canal network, important components of agricultural water supply, is 184,000 km. Major problem faced by irrigation facilities management is that these facilities are spread over an irrigated area at a low density and are difficult to access. In addition, the management of irrigation facilities suffers from missing or errors of spatial information and acquisition of limited range of data through direct survey. Therefore, it is necessary to establish and redefine accurate identification of irrigated areas and canal network using up-to-date high resolution images. In this study, previous existing data such as RIMS (Rural Infrastructure Management System), smart farm map, and land cover map were used to redefine irrigated area and canal network based on appropriate image data using satellite imagery, aerial imagery, and drone imagery. The results of the building the digital infrastructure in rural areas are expected to be utilized for efficient water allocation and planning, such as identifying areas of water shortage and monitoring spatiotemporal distribution of water supply by irrigated areas and irrigation canal network.

The purpose of this study was to assess the performance of the role and function of some industrial nurses and to characterize the factors affecting the performance of their activities. Thus the results could be used to suggest the direction in the performance of industrials nurses' activities effectively. During a period from January 10 to March 31, 1994, the data were collected from 87 industrial nurses, who were working as health managers in the plants, in Ulsan city and the vicinity in Kyungnam province, using a structured questionnaire. The results were as follows : 1. The general characteristics of industrial nurses in this study were 82.8% being 30 years old or less, 60.9%, being not married, and 93.1% having eduction levels above junior college. 2. With respect to general work conditions, 94.3% were working in a separate room provided for health care division, 40.2% working under the safety and health department, and 98.9% working as common-level staffs. And 60.9% were working less than 44 hours a week, 70.1% had work experiences less than 5 years, and 50.6% had annual incomes ranging 10 to 14 million wons. 3. As work conditions related to health care activities, 49.4% performed the activities not related to health care as always or occasionally, and 87.4% answered that occupational physicians were appointed in their plant and among them, however, only 6.9% worked on full-time basis and 52.8% perform little activities as occupational physicians. For a decision related to health care activity, 69.0% discussed the problems with the supervisors, and 19.5% made decisions by themselves. 4. As for attitude and perception to their activities as health managers, 66.7% moderately recognized the importance of health manager in the workplace, with 63.2% being satisfied their wages and treatment from the company, 57.5% being satisfied with their job positions and 51.7% having positive attitudes as being health managers. 5. The degree of performance at least in one of health related activities were very high in activities such as general medical care(100%), general health examination(98.0%) and specific health examination(100%), and relatively high in health education(72%), new employee health examination(60.9%), document handling(79.3%) and activity for work environment(70.1%). However, the performance rate was very low in preparing protective equipment (20.8%). 6. The levels of activities related to health care were significantly high when making decisions by themselves, when occupational physicians not being full-time, and when satisfying their job positions, and, on the other hand, significantly decreased as work hours increased. 7. In addition to some kinds of periodic education asked by all of the nurses, 89.7% wanted a specialized licensing system for industrial nurse, and 97.4% wanted to apply for the license test. As a conclusion, it is suggested that industrial nurses should be given more authority and placed in more self-controlled system to perform health care and other activities more efficiently, and the role and function of the occupational physician should be clearly distinguished from that of the industrial nurse as a health manager to avoid an unnecessary overlapping.
