The study aimed to project inflows and demmands for the agricultural reservoir watersheds in South Korea considering a variety of regional characteristics and the uncertainty of future climate information. The study bias-corrected and spatially downscaled retrospective daily Global Climate Model (GCM) outputs under Representative Concentration Pathways (RCP) 4.5 and 8.5 emission scenarios using non-parametric quantile mapping method to force Soil and Water Assessment Tool (SWAT) model. Using the historical simulation, the skills of un-calibrated SWAT model (without calibration process) was evaluated for 5 reservoir watersheds (selected as well-monitored representatives). The study then, evaluated the performance of 9 GCMs in reproducing historical upstream inflow and irrigation demand at the five representative reservoirs. Finally future inflows and demands for 58 watersheds were projected using 9 GCMs projections under the two RCP scenarios. We demonstrated that (1) un-calibrated SWAT model is likely applicable to agricultural watershed, (2) the uncertainty of future climate information from different GCMs is significant, (3) multi-model ensemble (MME) shows comparatively resonable skills in reproducing water balances over the study area. The results of projection under the RCP 4.5 and RCP 8.5 scenario generally showed the increase of inflow by 9.4% and 10.8% and demand by 1.4% and 1.7%, respectively. More importantly, the results for different seasons and reservoirs varied considerably in the impacts of climate change.

Purpose: The purpose of this study was to clarify the causal relationship and correlation between audit quality and audit performance and to analyze theoretical discussions and actual facts in order to improve audit performance on public enterprise audit and to identify what factors contribute to management and to seek ways to secure business performance. Methods: In this study, theoretical consideration was conducted that concerned the definition of audit, the concept of internal audit, the audit quality and the audit performance after having considered advanced researches, related regulations, and literatures. Through the foundation of such theoretical consideration, the components of the audit quality were deducted and each component's impact on the audit performance was empirically proven. The collected data through the survey were analyzed using multi-regression analysis. The measurement tools used for this study were divided into three dimensions such as internal quality, interaction quality and environmental quality. Result: First remark, out of the various components of the audit quality, independence, professionalism, and empathy appear to positively impact the audit degree of satisfaction. However, the measure of sufficiency is shown to bear no correlation to the audit degree of satisfaction. Second, out of the various components of the audit quality, professionalism, sufficiency, and empathy appear to positively impact the audit degree of applicability. However, the measure of independence is shown to bear no correlation to the audit degree of applicability. Third, audit quality appears to positively impact the audit degree of satisfaction and applicability, and also the performance of management. Concusion: It appears that the audit quality positively impacts the audit degree of satisfaction, applicability and management performance indicated by the audit performance.

기존의 자원봉사 및 사회봉사 활동은 교과목과의 직접적인 연결고리가 없었다. 봉사학습은 직접적이고 의도적으로 교과 수업과 지역사회 봉사활동을 통합한 교육방법 중의 하나이다. 연구에 따르면, 교과수업과 봉사의 통합은 수업에서 학생들의 학습 의욕을 높이고, 사회문제 해결에 적극적인 자세를 가지게 해주며, 봉사의 가치를 알게 해 준다는 이점이 있다. 또한, 이 방법은 창의적 문제해결기법을 익히면서 전공과 관련된 프로젝트를 수행하기 때문에 최근 공학교육 분야에서의 KEC 2005 기준의 많은 측면을 적용할 수 있는 환경을 제공해 준다. 더불어 지역사회 공학프로젝트를 수행하게 되므로 창의적 문제해결력과 더불어 봉사 마인드를 함양할 수 있는 좋은 교육방법으로 알려져 있다. 본 연구에서는 봉사학습이 왜 새로운지, 다른 학습활동과는 어떤 차이가 있는지, 다른 대학들은 어떻게 운영하고 있는지 등에 대해 살펴보고, 공학 분야에서 봉사학습 교과목 및 프로그램 운영을 위한 전략을 제안하고자 한다.

In April 2001, many Japanese national institutes were reorganized as Independent Administrative Institutions (IAI) based on the General Act for Independent Administrative Institutions and the act for each institution. Under the Ministry of Education, Culture, Sports, Science and Technology (MEXT), the National Institute for Materials Science (NIMS) was established by the merger of the National Research Institute for Metals (NRIM) and the National Institute for Research in Inorganic Materials (NIRIM). One of the biggest changes was the expansion of autonomous administration. The nanotechnology and material R&D field was prioritized in the 2nd (2001-2005) and the 3rd (2006-2010) Science and Technology Basic Plans; subsequently, NIMS was assigned to take the initiative in nanotechnology as well as materials science. NIMS has proactively expanded research fields through the introduction of researchers from polymers, electronics, and biotechnology as well as member institutes of the World Materials Research Institute Forum (WMRIF). Globalization has been promoted through programs that include the International Center for Young Scientists (ICYS) and the International Center for Materials Nanoarchitectonics (MANA). The 4th Science and Technology Basic Plan (2011-2015) emphasizes outcomes-recovery and rebirth from the disaster, green innovation, and life innovation. The Midterm Plan for NIMS also follows it. R&D collaboration by multi-partners (that include industry, university, and GRI) should be strategically promoted where GRI are especially required to play a hub function for innovative R&D and open innovation. NIMS highlights are Tsukuba Innovation Arena (TIA) and the Nanotechnology Platform Project. On January 20, 2012, a new organization was decided on by the Japanese Government where several IAI from different science and technology areas will be merged to realize more effective R&D as well as administrative cost reductions. NIMS is also supposed to be merged with 4 other R&D IAI under MEXT by the end of 2013.

The research presented here represents a collaborative effort with the SFWMD on developing scenarios for future climate for the SFWMD area. The project focuses on developing methodology for simulating precipitation representing both natural quasi-oscillatory modes of variability in these climate variables and also the secular trends projected by the IPCC scenarios that are publicly available. This study specifically provides the results for precipitation modeling. The starting point for the modeling was the work of Tebaldi et al that is considered one of the benchmarks for bias correction and model combination in this context. This model was extended in the framework of a Hierarchical Bayesian Model (HBM) to formally and simultaneously consider biases between the models and observations over the historical period and trends in the observations and models out to the end of the 21st century in line with the different ensemble model simulations from the IPCC scenarios. The low frequency variability is modeled using the previously developed Wavelet Autoregressive Model (WARM), with a correction to preserve the variance associated with the full series from the HBM projections. The assumption here is that there is no useful information in the IPCC models as to the change in the low frequency variability of the regional, seasonal precipitation. This assumption is based on a preliminary analysis of these models historical and future output. Thus, preserving the low frequency structure from the historical series into the future emerges as a pragmatic goal. We find that there are significant biases between the observations and the base case scenarios for precipitation. The biases vary across models, and are shrunk using posterior maximum likelihood to allow some models to depart from the central tendency while allowing others to cluster and reduce biases by averaging. The projected changes in the future precipitation are small compared to the bias between model base run and observations and also relative to the inter-annual and decadal variability in the precipitation.
