The purpose of this study was to identify the effects of wives' economic contributions and sex-role attitudes on couples' decision-making for use in family education and to improve stable couple relationships. This study targeted 286 married women who have a child or children. The main results of this study indicate that almost half of the participants showed that their couple decision-making, economic resource contributions and sex-role attitudes were husband-dominated. Additionally, the participants' most modern sex-role attitudes were toward gender stereotypes, though the most conservative attitudes were toward women and men's household lives. The variables that distinguished between husband-dominated and equality couples were age, education level, spouse's average income and resource evaluation; related, age, education level, spouse's average income, contribution toward household management and the occupational life of the woman were the variables that distinguished between husband-dominated and wife-dominated couples. This study also revealed the variables that affect couples' decision- making, demonstrating the necessity of considering several variables in the approach to the decision-making process of individual couples.

This study is concerned with educational services provided for archives with a focus on programs for teachers and students in the classroom. The purpose of this study is to develop the archival-resource based learning model. And the other purpose is to find out the influence of the archival-resource based learning. The researcher and teachers designed two lessen plans for archival-resource based learning and general learning. To compare with the archival-resource based learning and the general learning, the researcher divided into two comparison classes of 6th graders of two elementary schools. Statistical analysis was conducted by analysis of covariance using SPSS WIN 12.0 for t-test.

Comparative evaluation of offshore wind retreival software, which use the satellite images taken by Synthetic Aperture Radar sensor; SARTools of CLS-SOPRONO, France and SpaceEye of London Research and Development Corporation, Canada is carried out. For a reference satellite image, ENVISAT ASAR imagery of Jeollanam-do Wan-do area when the winter-time northwestern wind prevails is processed by CMOD_IFR2, CMOD4, CMOD5 algorithms. Wind speed difference and its relative ratio are calculated to evaluate uncertainty of software selection.

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.

This paper was carried out desertification area change detection from 1980s to 2000s per unit decade using by multitemporal satellite images (Landsat MSS, TM, ETM+). This study aims to use Spectral Mixture Analysis (SMA) to identify and classify study area. Endmembers is selected bare soil, green vegetation (GV), water body using by Minimum Noise Fraction (MNF). Endmembers used to generate increase and decrease images respective from 1980s to 1990s and from 1990s to 2000s. From the analysis of multitemporal change detection for three periods, it was apparent that the area of bare soil increased significantly, with simultaneous decrease of GV and water body. The multitemporal fraction images can be effectively used for change detection. Though there is no field survey dataset, SMA is reliable result of change detection in desertification in China.

Forming Community is important to manage and provide the service in Ubiquitous Environments including embedded tiny computers. Community Computing is that members constitute the community and cooperate. A mutual exclusion problem occurs when many processors try to use one resource and race condition happens. In the expanded concept, a group mutual exclusion problem is that processors in the same group can share the resource but processors in different groups cannot share. As mutual exclusion problems might be in community computing environments, we propose algorithm which improves the execution speed using RMS (resource management service). In this paper describes proposed algorithm and proves its performance by experiments, comparing proposed algorithm with previous method using quorum-based algorithm.

This letter considers the problem of resource sharing among a relay and multiple user nodes in cooperative transmission networks. We formulate this problem as a sellers' market competition and use a noncooperative game to jointly consider the benefits of the relay and the users. We also develop a distributed algorithm to search the Nash equilibrium, the solution of the game. The convergence of the proposed algorithm is analyzed. Simulation results demonstrate that the proposed game can stimulate cooperative diversity among the selfish user nodes and coordinate resource allocation among the user nodes effectively.

Most of dredged soil generating millions of tons per year is treated as a waste disposing in ocean or landfill except some part of recycling. The purpose of this study is to present the prerequisite for the use of dredged soil as a resource and analyse economic and environmental values of the recycling of dredged soil. The analysis of the economic and environmental value of recycling of dredged soil as a resource showed that several trillion won of budget can be saved in construction of disposal area or landfill and that loss of about 50 million tons of aggregates from deforestation can be restored by supplyment of dredged soil preserving a mountain as big as the Namsan(Mt.) every year. In order to utilize dredged soil in more diverse areas as high value of resource, the related domestic laws are needed to be readjusted integrating laws spreaded in different government departments and a special law is prepared and enacted.

연구목적: 본 연구는 미국 인디애나 주에 소재하는 중학교와 고등학교 학생들 사이의 methamphetamine, MDMA, GHB, and Rohypnol과 같은 약물사용 특성을 파악하고 청소년 약물사용과 관련된 성과 학교 환경에 대한 인지된 안전도 특성을 분석하였다. 연구방법: 본 분석에 사용된 데이터는 Indiana Prevention Resource Center (IPRC)에서 2007 년도에 수행한 음주, 흡연, 약물사용 설문조사(ATOD) 응답자료로서 인디애나 주에 거주하고 있는 6-12 학년 사이의 학생들을 편의추출하여 조사가 가능했던 158,632명의 응답을 얻었다. 연구결과: 로지스틱 회귀분석에서 조사한 4개 약물을 사용하는 학생들의 관심도는 교실에 있을 때, 복도에서 혼자 있을 때, 방과후 활동을 위해 학교에 남아있을 때 불안전하다고 느끼는 약물 미사용자보다 더 높은 경향을 보였다. GHB, MDMA, Rohypnol을 사용한다고 응답한 학생이 여자보다 남자에서 더 많았고 상관관계분석 결과, 메탐페타민을 비롯한 네 가지 약물 사용의 상호간 상관도가 모두 유의미하게 높았다.

In the Is-95 soft handoff scheme of CDMA, there occurs a tradeoff between improving quality due to the space diversity and additional resource management like updates of the active set during soft handoffs. In addition, if a mobile terminal is alternating two adjacent cells, a well-known phenomenon called ping-ping causes the resource management to be seriously degraded. By noting that in general the probability that a user initiates additional handoffs is exponentially decreased as the user has already handed over one or more times, we present a soft handoff algorithm making use of handoff profiles of mobile terminals to improve resource utilization. In the proposed algorithm the number of handoffs made so far during the call is recorded in the mobile profile and the profile data is used for adjusting handoff parameters such as the value of add or drop threshold (T_ADD or T_DROP). Through simulations, the result of the proposed algorithm is shown to improve the handoff performance by lowering the number of handoffs while simultaneously reducing resource waste.
