The purpose of this study was to analyze the impact of parental resources and parenting stress on parenting efficacy in low-income families Furthermore, in order to verify whether parental resources function as a resilience factor, a structural model was established to assess the suitability and influence of the variables. A total of 603 parents of children and adolescents between the ages of 9-18 were selected from the data from Children and Adolescents Comprehensive Status Research (2009) by the Ministry for Health, Welfare and Family Affairs. For the analyses, SPSS WIN 18.0 and AMOS 18.0 were utilized. The major results were as follows: First, the suitability of the model was confirmed with variables presenting a satisfying fit. Second, parental resources had a negative effect on parenting stress and a positive effect on parenting efficacy. Third, parenting stress had a negative effect on parenting efficacy. Finally, a test of the structural equation model supports the hypothesis that parental resources have a significant direct effect as well as an indirect effect through parenting stress on parenting efficacy. The implications for further studies and practice were discussed.

Nepal is bestowed with abundant water. With more than 1500 mm average annual rainfall in the country, a vast quantity of underutilized groundwater in the Terai belt, and the water stored in snowcaps in the Himalayas, aquifers in the mountains and glacial lakes, Nepal is potentially in an advantageous position in terms of per capita availability. However, low emphasis in management aspect of water and high emphasis in infrastructural developments related to water resources management has resulted in conversion of water in Nepal from a resource to a burden. The global climate change, reduction in number of rainy days, increase in intensity of rainfall during wet monsoon season, encroachment of river banks for settlement, inadequate release of environmental flows from hydropower plants, and attempt to tame the mighty and high velocity rivers of Nepal have resulted in increasing number of water induced disasters (flood and landslide), rise in conflict between local residents and hydropower developers, higher number of devastating landslides, and in some extreme cases mass migration of residents resulting in climate refugees. There is a ray of hope; the awareness level of the people regarding sustainable use of water resources is increasing, the benefit sharing mechanism is gradually being implemented, the role of interdisciplinary and integrated water resources management is appreciated at a higher level and the level of preparedness against flood and landslides is at a higher degree compared to a couple of decades ago. With the use of renewable energy sources, the possibilities for sustainable and productive use of water are on the rise in Nepal.

In general, a damage that occurs due to landslide or slope failure in urban areas is larger than that in rural areas. In order to reduce the damage, a program is necessary to categorize slopes based on properties and to manage them systematically. Based on the above necessity, a slope management program which is applicable to slope management in an urban area has been developed at Hwangryung mountain in Busan as a target area. The program has a function of systematic slope information constructed by slope ID number of each slope or sub-region of a mountain, making a slope data sheet, analysis and grouping of slope stability, and establishment of a data base. It can also be utilized practically by end users due to the convenient input, edition, printing, management and operation of slope data. For practical utilization of the developed program, a research related to construction of the slope management system for a regional area is demanded to be performed continuously. The supply and utilization of a web based slope management system would contribute to damage reduction.

This research will mainly focus on security issues in a university campus and delve into the risk factors and its characteristics due to the extreme polarization growth, and ultimately conduct research on legislative issues regarding safety & security management. A university campus is a miniature of the society, concentrated with human resources, material resources and knowledge information resources. It is also a region in which various underlying risk factors threaten these resources. However, due to the insensibility of danger and carefree indolence, these risk factors have been ignoring, leaving university campus amidst a "dead zone." Currently, a systematic and synthetic measures not only for safety inside the laboratory but also for the new type of crimes such as cyber crimes and motiveless crime due to extreme polarization, stress, uneasiness about the future, increase of mental illnesses, and drug abuse are urgently required. Therefore, I would like to introduce a legislative program in a crisis management perspective that can prevent universities from danger and protect the resources which would ultimately create a new security system.

The population of small yellow croaker, Larimichthys polyactis, in the Yellow and East China Seas has decreased significantly since the mid 1970s. Several management measures have been introduced to conserve it, but population size remains low. To rebuild this population, it is now necessary to consider more effective management methods based on the stock assessment. To determine long-term population changes, fishery and biological data collected over 34 years (1969-2002) were analysed. Yearly fish length compositions were analysed for the time periods 1968 through 1970, 1978 through 1982, and 1993 through 2002; and catch data was available from 1969 to 2002. Annual population sizes were calculated based on length composition, the relationship between total length and body weight, and total landings. Analyses showed that since the 1970s, average size of harvested fish decreased; the proportion of less mature fish (smaller than the 50% maturity length, 19cm) in catches has increased and the estimated biomass has decreased significantly. Consequently, the main management recommendation is that juvenile fish need to be better protected to allow the rebuilding of resources to a more sustainable population level. This will require fish size limit, permissible mesh size, and closed area and season regulations.

This paper presents the structure of an energy management system for distributed energy resources of a grid-connected microgrid. The energy management system of a grid-connected microgrid collects information of the microgrid such as the status of distributed energy resources and the time varying pricing plan through various protocols. The energy management system performs forecasting and optimization based on the collected information. It derives the operation schedule of distributed energy resources to reduce the microgrid electricity bill. In order to achieve optimal operation, the energy management system should include an optimal scheduling algorithm and a protocol that transfers the derived schedule to distributed energy resources. The energy management system operates as a rolling horizon controller in order to reduce the effect of a prediction error. Derived control schedules are transmitted to the distributed energy resources in real time through the international standard communication protocol.

It has been declared in 1992 at Rio about the management of united water control and method of the management of the water resources at the water basin. And it was also mentioned about the protection of fresh water's quality and it's supply under chapter the 18th of the agenda 21. It has been 10years passed after Rio declaration, and water crisis Is getting more serious than before. Fairly, right for using water resources was given to every life as the public resources. But at the last world water forum, water was commercialized, and regulated as the basic requirement not basic right. Therefore, we could use the water according to the logic of supply and demand at the market, and with money. Furthermore, construction of the big dam which was build to solve the problem of the lack of water became one of problems for water control. Korea is keeping consistent policy such as providing water by the building of dam. Control of the water demand is the most basic and effective policy for the preservation of water resources. If we change the policy such as the construction of the dam, we should put the management of the water demand in the center with the reliable philosophy. United management of the river basin has to be made with the security of water, improvement of water quality, and protection of the ecological side each other. Management of water basin also has to be completed to solve the trouble caused by using water conflict people who live up and down stream. To maintain the good quality of water, management of water basin is necessary. Also, bottom line of the united management of water basin is voluntary involvement of every citizens and local community. We suggest to preserve the origin of river and the upper at the ecological side. It is worth it to preserve.

The purpose of this study was to provide for the appropriate conflict management strategies to employed wives by investigation casual relations of conflict, resources, home management behavior and managerial satisfaction by applying a system's approach. The data were collected through the questionnaire whose respondent were 388 employed wives. The data were analyzed by various statistical methods such as Frequency, Percentage, ANOVA, F-test, T-test, Pearsons' correlation analysis, Multiple Regression analysis, Path analysys. The results of this study are as follows : 1) Input variables, throughput variables, output variables had differences significantly according to the family life cycle. The employed wives' families which are former term of the family life cycle used more appropriate conflict management strategies than latter term of FLC. That is, the employed wives' families which are former term of FLC had more abundant resources such as cohesive power of family, interaction with relatives, social support, had higher planning score, used more frequent structural management strategies. But, the managerial satisfaction had no differences. 2) For the relation of input variables and throughput variables, the more resources, the lower conflict is the higher planning, implementing score, structural management score. For the relation of throughput variables, the higher planning, implementing, structural management score is the higher managerial satisfaction score. For the relation of input variables and output variables, the more resources, the lower conflict is the higher managerial satisfaction, besides objective and material resource, subjective and psychological resource had influence. 4) among all variables affecting the managerial satisfaction, the commition of housework, cohesive power of family, wives' occupational level had indirect effect on managerial satisfaction through structural managemenet. Only the income had direct effect on managerial satisfaction.

This research aims to analyze the usefulness of biological resources from the perspective of the users from various angles and after taking these factors into consideration, provide policy implication and scientific criteria for judging and choosing useful biological resources. Among biological resources defined in CBD, the subject of the research was confined to the biological resource as a unit which can be actually used in benefit sharing and trade. Also, among diverse values of biological resources, the usefulness was assessed focusing on the utility value and scarcity. Usefulness was rated on a scale of 1 to 5 (5 grades). The rating was adjusted for the biological resources that need to be managed as a part of the management policy. It is expected that the criteria of this study will be useful for the following: (1) the procurement of biological resources in the need for primary protection and management (2) the utilization of secured biological resources by analyzing their utility value and using them in biological resources industry (3) securement of sovereignty over biological resources, such as prior access permit under the Nagoya protocol, through management and protection of biological resources in Korea.

Cloud computing is becoming an effective and efficient way of computing resources and computing service integration. Through centralized management of resources and services, cloud computing delivers hosted services over the internet, such that access to shared hardware, software, applications, information, and all resources is elastically provided to the consumer on-demand. The main enabling technology for cloud computing is virtualization. Virtualization software creates a temporarily simulated or extended version of computing and network resources. The objectives of virtualization are as follows: first, to fully utilize the shared resources by applying partitioning and time-sharing; second, to centralize resource management; third, to enhance cloud data center agility and provide the required scalability and elasticity for on-demand capabilities; fourth, to improve testing and running software diagnostics on different operating platforms; and fifth, to improve the portability of applications and workload migration capabilities. One of the key features of cloud computing is elasticity. It enables users to create and remove virtual computing resources dynamically according to the changing demand, but it is not easy to make a decision regarding the right amount of resources. Indeed, proper provisioning of the resources to applications is an important issue in IaaS cloud computing. Most web applications encounter large and fluctuating task requests. In predictable situations, the resources can be provisioned in advance through capacity planning techniques. But in case of unplanned and spike requests, it would be desirable to automatically scale the resources, called auto-scaling, which adjusts the resources allocated to applications based on its need at any given time. This would free the user from the burden of deciding how many resources are necessary each time. In this work, we propose an analytical and efficient VM-level scaling scheme by modeling each VM in a data center as an M/M/1 processor sharing queue. Our proposed VM-level scaling scheme is validated via a numerical experiment.
