One of the main issues in natural resource economics is estimating the amount of stock and the biological growth functions of renewable natural resources. Since the stock level is not directly observed the usual econometric approaches cannot be employed for this purpose. The maximum entropy approach has been suggested as a useful alternative to estimate the dynamic model of natural resource use. This study estimates the stock and the growth function of Korean anchovy using the data for yield and yield efforts. The results show that the current level of anchovy yield exceeds its maximum sustainable yield, which implies that the stock will decrease substantially over time.

Si-Hwa tidal power station is using difference of the ebb and flow. The active power is dependent on up and down sea water level but if it is drastically changed because of a typhoon or waves the generator terminal voltage and active power is changed that is a chief cause of power station unstability. Therefore this paper arrange a present state of power or frequency fluctuation and generator terminal phase difference in case of occurrence a drastic change of sea water level.

The purpose of this study is to structure finance management education programme and to provide basic data orienting finance service system by means of analyzing the level of financial problem and its influential variables. The following is the result of this study: First, the level of financial problem perceived by housewife in urban areas is in the following order ; property which is perceived the least. Second, the level of financial problem perceived by housewife in urban areas is dependant on housewife age, husband education level, husband occupation, the degree of property, the degree of debts, tendency of fortune control, tendency of materialism, feeling of appropriate resource. It is especially noting that housewife in forties shows high level of financial of financial problem recognition than housewife in twenties does. This indicates needs for middle for middle-aged home management in which happens house moving to larger size, education of children, marriage of children, preparation for stabilization basis after children’s marriage, and shortage of surplus money. Third, variables which affect all sub-areas are family property sum, tendency of materialism, feeding of appropriate resources. The less family property sum, the stronger tendency of materialism, and the more perceive feeling of appropriate resources, the more perceive they financial problems.

This study aimed for in-depth observation of the status quo of the youth generation's happiness utilizing the Better Life Index and the World Value Survey. To serve this purpose, the study selected 11 of the Organization for Economic Cooperation and Development(OECD) member countries (Australia, Estonia, Germany, Japan, Korea, Mexico, New Zealand, Poland, Sweden, Turkey, United States) that overlapped with the subject countries of the World Value Survey. The results of the observation first revealed that among the work-life balance levels of youth generations from across the 11 studied countries, the level for Korean youth was in a very poor state. Second, the happiness level of Korean youth also sat among the bottom ranks, with the aspects of politics, friendship, and career casting a heavy influence on importance to life; specifically, the youth generations of Turkey and Germany showed high levels of life purpose, while Korean youth displayed outstanding results in the challenge aspect. The third finding of this study reported that family, religion, power, benevolence, and challenge were commonly related to the happiness level of youth generations in countries with a higher work-life balance. The results of this study are expected to contribute to the much needed attention and support for improving the happiness level of the Korean youth generation, who will eventually play the leading role in our future society.

Resource-constrained project scheduling is to allocate limited resources to activities to optimize certain objective functions and to determine a start time for each activity in the project such that precedence constraints and resource requirements are satisfied. This study suggests a multi-project scheduling model which can level work loads, make the most of production capacity and restrain the delay of delivery by developing a heuristic algorithm which minimizes the project completion time and maximizes the load rate under resource constraints.

This study aims to figure out factors influencing health and moderating effect of social support resource between those factors and health of low income women in diverse spheres. The data of low income women were 239 cases and were utilized SPSS ver. 21 program. The main results of this study are as follows: firstly, health of low income women is identified medium level. Secondly, education level, self-efficacy and social support resource are related to the self-rated health of low income women. Especially, social support resource functions as moderators on between education and self-rated level of the health of low income women. Consequently, the findings suggest the need to expand the social intervention range to promote health of low income women from cost benefit to psychological support such as capacity building for self-management and establishment of safety-net to extend social support. And subsequently, the time attribute of the factors related to low-income women's health and the diverse characteristics of the subjects should be considered.

This study takes an effort to suggest solutions for medical service consumers' sovereignty. Specifically, consumer evaluation, information seeking level, and affecting factors on information seeking level were explored in terms of medical service. In present study, medical information included medical institution and doctors, prescription, diseases, medical treatment and medical expense. Medical service consumers' information seeking is identified as consumers' own efforts to acquire medical information through various sources. The analysis results suggested that consumers' information seeking level is even lower, while their evaluation level is somewhat low. Moreover, the result for information seeking level by consumer characteristics implied that people who have high education, high economic status, medical knowledge, and high attitudes for consumer right are active information seekers. Finally, consumer attitudes for right appeared most influential factor on information seeking level, implying direction for medical service consumer education.

We suggest resource authorization system based on RBAC admitting someone to access resources. In existing grid environment, The authorization mechanism on user's resource is to give users an authority on the basis of DN(Distinguished Name) of proxy certificate and map file mapped in local system ID by one-to-one. In this case, it is difficulty in resource management such as each accounting management, memory resource, and disk resource, if the number of users, who want to use them is increased. To solve this problem, we specify the role of user's task in extension fields of his proxy certificate instead of the authorization mechanism of user's ID and propose resource authorization system being able to access his resource.

Recently, artificial intelligence techniques have been widely used in the computer science field, such as the Internet of Things, big data, cloud computing, and mobile computing. In particular, resource management is of utmost importance for maintaining the quality of services, service-level agreements, and the availability of the system. In this paper, we review and analyze various ways to meet the requirements of cloud resource management based on artificial intelligence. We divide cloud resource management techniques based on artificial intelligence into three categories: fog computing systems, edge-cloud systems, and intelligent cloud computing systems. The aim of the paper is to propose an intelligent resource management scheme that manages mobile resources by monitoring devices' statuses and predicting their future stability based on one of the artificial intelligence techniques. We explore how our proposed resource management scheme can be extended to various cloud-based systems.
