SE generally defines approaching ways of conducting identification, verification and integration of an optimized product and process solution to meet customer's needs by leveraging organizational competency in engineering and management. To successfully develop a new product under mass production contract, it is important to efficiently carry out the program by ensuring that three major competencies are secured; core technology, system integration, and program management. For successful implementation of tasks in the three areas, systematic execution is called for, which requires identifying risk factors in advance. In particular, comprehensive risk management role and responsibility is required for program management. Success of a development program is determined by complex elements of human resources, organization culture, and overall competency of an organization in technology and program management, including capability of the program manager. In this paper, a risk management solution is suggested to lead a program to success with a more efficient way through actual risk management by the concept of SE around the above three areas.

Multicast and Broadcast Service (MBS) provides flexible and efficient transmission of the same information to multiple users using shared radio resources on WiBro network. The advantage of this service is to achieve the most efficient use of radio and network resources as well as to lessen sender's processing load when sending the same information to multiple users. Though radio resources are saved since a multicast or broadcast transport connection is associated with a service flow, it is hard to change MBS service channel dynamically. In this paper, we propose a Radio Resource Management System (RRMS) for supporting dynamic scheduling of MBS service channels. Results show that our proposed scheme using Radio Resource Allocation Table (RRAT) can efficiently support MBS services by providing dynamic schedule for MBS service channels.

In 1997, in the course of overcoming economic crisis caused by the shortage of foreign currency there was a significant phenomenon, the irregularization of human labour resources. There was no exception in hospital, either. Most hospitals put a lot of thought to solve the problem about irregular workers. Between employee and employer the problem of irregular workers has been raised as a main topic of all. The objectives of this study were to inspect the actual state of irregular workers and to understand the positive effect of protecting irregular workers, recently established and revised, on the human resources management of hospitals. After enacting irregular labours protection acts there were many opinions that the labour rules of hospitals would be changed.(56.7%). The plan to solve irregular worker's wage issues would he carried out step by step, but some hospitals have not examined the plan yet,(81.9%). Many hospitals had a plan that irregular worker's wage would be actualized in two or three years.(78.3%) The method, to solve the problem of irregular workers arc as follows: 1) the introduction of functional wage system, 2) the convert from automatic rising wage system to annual wage system, 3) the incentive grade system according to management result, 4) lower functional group wage system, 5) non-term contract wage system. From the point of the opening medical market and securing competitive power of hospitals, it is prospected that irregular works would be increased also in future. So to manage irregular workers effectively would be essential in maintain hospital's competitive power and improve medical service. The result, of this study were a, follow: (1) In hospital, the ratio of irregular workers in hospitals was lower than that of all irregular workers in Korea. (2) In hospital, the wage level of irregular workers was higher than that of irregular workers in Korea. (3) In hospital, the social insurance application ratio of irregular workers was higher than that of all workers in Korea. (4) In hospital, there seems to be no appropriate and active measures to improve labour condition of irregular workers, yet. (5) In many hospitals, the policy of irregular workers would be expected to revised for the law standards. In this study the actual conditions and problems of irregular workers were proposed and it was expected to contribute decisions-making in hospital management, especially when using human resources.

Currently, environment-friendly and sustainable fisheries are one of the major issues among fisheries authorities. A variety of alternative management policies and projects are going on to enhance fisheries management systems and fishery resources such as a TAC management program and a VDS (Vessel Day Scheme) management scheme for distant water fishing nations in Western and Central Pacific Fisheries Commission (WCPFC) convention area. These kinds of efforts among fisheries management authorities are aimed at limiting fishing capacity or fishing power. In terms of fisheries management, Fishing capacity and fishing power have increased the importance of the impact on a fishery and level of the resources. Increased fishing capacity and fishing power have caused not only depletion of fisheries resource, but also additional fishing cost. therefore, there is a clear need for authorities to manage fishing capacity and fishing power. It is also help ensure the conservation and sustainability of the fishery resources. Because of lack of data, absolute fishing power is difficulty to measure. The notion of relative fishing power is frequently used. In this study, relative fishing power was assessed using Mastuda (1991) method for fishing power index. The raw data for assessment was based on fishermen's logbook data from sampled fishing vessels in coastal snow crab gillnet fishery. Data Envelopment Analysis (DEA) method was used to assess fishing capacity. DEA is a linear programming methodology to measure the efficiency of a set of entities called Decision-Making Units (DMUs). It was recommended by FAO for assessing capacity in fisheries.

최근의 유역통합관리는 용수공급, 수력발전, 그리고 유지용수 등과 같은 기존의 운영방안과 더불어 수량, 수질, 생태계 보호를 함께 고려해야만 하는 등 운영목적이 복잡해지고 시스템 또한 대규모화 되고 있다. 더불어 용수이용 혹은 유역간 서로 상충되는 이해관계가 발생함에 따라 물이용의 효율성을 극대화할 수 있는 범 유역 단위의 수자원 계획 및 운영이 필요하게 되었다. 최적화 모형의 현실 활용 기회를 높이고, 수자원관리의 다양한 운영목적을 수자원 운영에 반영하기 위하여 본 연구에서는 저수지 운영률을 개발하고 이를 적용하기 위한 KModSim의 수문학적상태방법에 대한 적용성을 검토하였다. 본 연구에서 개발된 운영률은 전체적으로 용담댐과 대청댐의 실적저류량을 잘 재현하는 것으로 나타났으며, 이를 최적화 모형에 활용한다면 관행적으로 적용해온 물수지 분석 방법을 개선할 뿐만 아니라 유역통합수자원관리가 가능할 것으로 기대된다.

Korean Government has been promoting Four River Restoration Project (i.e., Han, Geum, Nakdong, and Yeongsan rivers) since the second half of 2008. This project is expected to protect against floods and droughts by water resources management. Many researchers have study water resources management, but most studies were focused on direct runoff. However, in order to efficiently protect against floods and droughts, baseflow should be studied as well as direct runoff. Because baseflow has a great effect on streamflow, it needs to be correctly analyzed. For more accurate analysis of baseflow, direct runoff and baseflow from streamflow should be separated first. In this study, 12 flow gauging stations of four major rivers were selected, and flow data from them were obtained (2004-2010) through WAMIS and Web-based SWAT Bflow system (http://www.envsys.co.kr/~swatbflow) which was used to separate direct runoff and baseflow. Baseflow values of Pass 2 in SWAT Bflow system were used. As a result of this study, baseflow contribution was ranged from 23.4% to 68.6% and accounted for about 50% of streamflow. Through this study, it shows that in the case of the flow fluctuation, baseflow is more affected than direct runoff by changes in streamflow in a flood or dry season. Thus, baseflow estimation should not be overlooked for efficient water resources management. However, it has a limitation in this study that because this study used to select randomly 12 flow gauging stations, it did not show a common tendency on each watershed. It is important that flow gauging stations reflected on topographic characteristics of each watershed should be selected in a rigorous manner for further reliable and accurate baseflow estimation on four major rivers.
