Uncertainty is central to energy and climate policy. A growing number of literature show that almost all components of energy and climate models are, to some extent, uncertain and that the effect of uncertainty on the model outputs, in turn policy recommendations, is significantly large. Most existing energy and climate-economy models developed and used in Korea, however, do not take uncertainty into account explicitly. Rather, many models conduct a deterministic analysis or do a simple (limited) sensitivity analysis. In order to help social planners to make more robust decisions (across various plausible situations) on energy and climate change issues, an uncertainty analysis should be conducted. As a first step, this paper reviews the theory of decision making under uncertainty and the method for addressing uncertainty of existing probabilistic energy and climate-economy models. In addition, the paper proposes a strategy to apply an uncertainty analysis to energy and climate-economy models used in Korea. Applying the uncertainty analysis techniques, this paper revises the FUND model and investigates the impacts of climate change in Korea.

The major objectives of this study are twofold. The first is to discover which in-store tactics influence store performance when a retailer implements category management in variety enhancer and fill-ins categories. The second is to analyze how and why specific in-store tactics achieve better or worse performance than other in-store tactics across categories. The data were collected using scanner data and direct observations in 'A' discount store which is one of the representative discount stores in Korea. The in-store tactics were measured by product assortment, temporary price discount, price and non-price promotion, and shelving. The store performance was measured by sales and gross margin return on inventory investmant(GMROI). Empirical results analyzed by multiple regression were as follows: In variety enhancer category, the significant factors affecting sales were product assortment, temporary price discount, price promotion, and shelving. Non-price promotion also influenced GMROI positively but product assortment impacted on GMROI negatively. In fill-ins category, the significant factors affecting sales and GMROI were product assortment and shelving. However, the other factors such as temporary price discount, price promotion, and non-price promotion had no significant influence on both sales and GMROI. This paper presents a number of theoretical and managerial implications of the empirical results and concludes by addressing limitations and future research directions.

Purpose - Recently, creating shared value (CSV) has attracted attention through plan sustainability and the growth of corporate management. Porter and Kramer (2011) defined the core concept of CSV as social value, economic profits, improvements in the economic social condition, and reinforcing competitiveness. The purpose of CSV, which is to pursue economic profits through a social solution to the problem, agrees with managing the objective of a social enterprise that prioritizes the pursuit of profits through the realization of a social purpose. Today, CSV studies focus on CSR and sustainability and reinforce competitiveness. However, few studies focused on the social economy. Precedent studies examined CSV using a company example, and few studies exist from the perspective of consumers and the point of view of a market society. Research design, data, and methodology - Therefore, this study examines CSV in comparison to a background of the social economy. This study also investigates and analyzes the concept of social value from the point of view of consumers, social problems, consumption value, corporate value, and the influence of consumers. This article develops three hypotheses. Hypothesis 1 investigates the correlation with social innovation that consumers thought as being necessary for social innovation by a company. Hypothesis 2 is used to confirm the influence of consumers in CSV. Therefore, this article investigates the influence of consumers on consumption action for companies that are indifferent to social problems. Hypothesis 3 is used to verify the correlation between the value that consumers demand through consumption and the corporate value that companies pursue other than profits. The three hypotheses were adopted and met the standard for suitability. Results - The importance of the CSV study from the consumer perspective was confirmed using the influence of consumers on CSV. Because the objective of company activities is either the consumer or the market, the influence that extends to interactions between the company and consumers to ensure the success of a business is significant. Regarding the CSV study, because it was an initial study, various approaches are subsequently developed. However, conceptual and practical case studies on CSV currently exist that may be used to verify the factors that comprise CSV. Therefore, the company example may enable verification of the factors that influence the composition of CSV through identification from the consumer perspective. In addition, studying CSV as an action result (of consumer satisfaction, of a company's profits and competitiveness, and of society's cancellation of a social problem) may enable the realization of a practice paradigm as opposed to simply thought and faith. Conclusions - First, this study confirms the social value of a business through the feasible and common pursuit of consumers by corporations. Second, customer influence accounts for an important part of CSV. Third, shared value commonly provides a necessary advantage to consumers, corporates, and society, and contributes to the economy and healthy social development. Fourth, corporates can conduct a business, generate profits, and realize value through improvements in social problems and by addressing their competitive strengths and weaknesses.

As the disputes in the investment and civil/commercial sectors of China and Taiwan have increased due to active cross-strait economic exchanges, the Chinese government is addressing cross-strait disputes through various dispute resolution methods. In recent years, the Arbitration Center Across the Straits (ACAS) has been established to resolve disputes between cross-strait parties, while ACAS Arbitration Rules have been enacted and enforced. ACAS Arbitration Rules are prepared by referring to the Arbitration Act of China and Taiwan, the relevant provisions and practices of the China International Economic and Trade Arbitration Commission (CIETAC) Arbitration Rules and the cross-strait practical affairs of the China International Economic and Trade Arbitration Commission, and the cross-strait practical affairs giving consideration to the specificity of the cross-strait relationship and the characteristics of economic and trade disputes. Therefore, this paper has compared the features and main contents of the ACAS Arbitration Rules with those of the CIETAC Arbitration Rules. This refers to arbitration proceedings such as form and effect of arbitration agreement, decision of place of arbitration, and organization of arbitral tribunal; the provision of consolidation of multiple contracts and arbitration, and the provision of joinder of arbitration parties, which are implementing the "principle of party autonomy" with streamlining arbitration proceedings and reducing costs; "common, simple, and small sum arbitration proceedings which require shorter arbitration proceedings depending on the size of the arbitration object; and regulations on the "interconnection of mediation and conciliation" which is characteristic of China's arbitration system. Based on the above-mentioned main contents of the ACAS Arbitration Rules in China, there are some implications to be considered in the establishment of the Arbitration Rules of the South-North Commercial Arbitration Commission which will be applied to solve commercial and investment disputes arising from the Inter-Korean Economic Cooperation process, suggesting implications such as the need for the rapid composition and operation of the South-North Commercial Arbitration Commission, requirements for selecting arbitrators, expansion of the object of arbitration, specification of concreteness in deciding the place of arbitration, need to create a variety of arbitration proceedings, and application plan of the International Center for Settlement of Investment Dispute (ICSID) or Third Power Arbitration Agency.

Recently, demands with practical applications using high resolution imagery are increasing, according to addressing new sensor data. Since late 1990s, attempts for application to transportation problems of satellite imagery data have been intensively carried out in US, and these kinds of studies are being categorized into the name of RS-T(remote sensing in transportation). Further, this study is also linked with GIS-T(GIS for transportation), being in the matured stage, and then it contributes to wide uses of remotely sensed imagery. In this study, RS-T is briefly summarized. Later, in order to apply urban transportation analysis with satellite imagery as ancillary data, implementation, as prototyped extension program, for extraction of gravity-typed accessibility indices of transportation geography is performed in the ArcView-GIS environment. It is thought that applied results by two models among implemented models in this study can be utilized to characterize transportation accessibility in a region and to apply as useful statistics related to urban transportation status for regional transportation planning, if time series data are used.

The license plate recognition (LPR) unit consists of the following core components: plate region segmentation, individual character extraction, and character recognition. Out of the above three components, accuracy in the performance of plate region segmentation determines the overall recognition rate of the LPR unit. This paper proposes an algorithm for segmenting the license plate region on the front or rear of a vehicle in a fast and accurate manner. In the case of the proposed algorithm images are captured on the spot where unmanned monitoring of illegal parking and stowage is performed with a variety of roadway environments taken into account. As a means of enhancing the segmentation performance of the on-the-spot-captured images of license plate regions, the proposed algorithm uses a mathematical model for license plate colors to convert color images into digital data. In addition, this algorithm uses Gaussian smoothing and double threshold to eliminate image noises, one-pass boundary tracing to do region labeling, and MBR to determine license plate region candidates and extract individual characters from the determined license plate region candidates, thereby segmenting the license plate region on the front or rear of a vehicle through a verification process. This study contributed to addressing the inability of conventional techniques to segment the license plate region on the front or rear of a vehicle where the frame of the license plate is damaged, through processing images in a real-time manner, thereby allowing for the practical application of the proposed algorithm.

Purpose: The purpose of this study is to analyse research trends related to the evaluation of quality of nursing, thereby obtaining basic data relating to the identification of current situation of instrument development of quality of nursing, and of future research orientation and to the development of performance index of nursing organization. Method: The data were collected from June to December, 2002 through the review of total of 32 research papers which had evaluated quality of nursing among published papers in Korea from 1976 to August 2002. The analysis was done in terms of research period, the periodicals in which research papers were published, domains and the approaches of evaluation of nursing quality. The content analysis of lowest-level items amounting was performed using NIC developed by McCloskey & Bulecheck(1998) and consequential indices of quality of nursing developed by Chi(1995). Results: Twenty-three of 32 papers(71.8%) turned out to be published after 1995, indicating surging interest in the evaluation of quality of nursing from the mid 1990s. Also, ten of 12 research papers dealing with subjects' diseases were published after 1995. In content analysis of lowest-level items of the process-oriented evaluation of quality of nursing, the highest nursing intervention was patient education about procedure and treatment; followed in descending order by patient education about disease process, strengthening of communication, managing environment, infection control, admission care, defecation and urination care. In content analysis of lowest-level items of the outcome-oriented evaluation of quality of nursing, items of physical and psychological state, of patient and family satisfaction, of knowledge and home care, of change of patients' state, of addressing nursing issues, and of patient recovery were the outcome indicators in more than 60 percent research papers. Conclusion: The findings provided the foundation for their effective use in nursing practice with comparing and presenting various core evaluation items representing process and outcome domains.

The Cancun Agreements under the United Nations Framework Convention on Climate Change require developing countries aiming to undertake REDD+ activities to develop a national strategy or action plan, addressing the drivers of deforestation and forest degradation, a measurement, reporting and verifying (MRV) system including forest monitoring system, and safeguards to ensure equity and co-benefits for local communities and indigenous peoples, and biodiversity. The Government of Indonesia and the Government of Norway established REDD+ cooperation through signing a 'Letter of Intent' in May, 2010. Indonesia agreed on 'a two year suspension on all new concessions for conversion of peat and natural forest'. In turn, Norway agreed to support Indonesia's REDD+ implementation efforts up to one billion United States dollars. Indonesia's REDD+ national strategy (June, 2012) accepted most of the requests included in the 'Letter of Intent'. The REDD+ national strategy, however, does not reflect requests of the Cancun Agreements which noted identification of the drivers of deforestation and forest degradation and guarantee of real greenhouse gas emissions reductions. Indonesia lays emphasis on Norwegian requests which includes expected financial support rather than the Cancun Agreements which have a weak legally-binding requirements.

This study investigated the perceptions and the characteristics of elementary teachers on teaching science-arts integrated activities. Twelve elementary teachers who have taught in the third to sixth grade science lessons participated in this study. Data was collected by individual interviews lasting 60 to 90 minutes. Interview questions were composed of three aspects: 1) how elementary teachers perceive science-arts integrated activities, 2) in what ways elementary teachers address science-arts integrated activities, and 3) what difficulties elementary teachers experienced in addressing science-arts integrated activities. The results showed that, first, elementary teachers agreed that science-arts integrated activities have educational value in science learning. Second, most teachers focused on improving understanding of science knowledge through teaching science-arts integrated activities, while several teachers put emphasis on having experience of arts as well as understanding of science knowledge. And third, teachers experienced difficulties due to insufficient teaching materials and time to prepare for teaching science-arts integrated activities. Based on the results, we suggested educational implications for utilization of science-arts integrated activities in elementary education.

Vowel articulation in subjects related to speech disorders seems to be difficult. A chant method that properly reflects the characteristics of language could be used as an effective way of addressing the difficulties. The purpose of this study was to find out whether the chant method is effective as a means of enhancing vowel articulation. The subjects of this study were 60 normal adults (30 males and 30 females) in their 20s and 30s whose native language is Korean. Eight utterance conditions including chanting and reading conditions were recorded and their acoustic data were analyzed. The results of the analysis of the acoustic variables related to the formant confirmed that the F1 and F2 values of the vowel formants are increased and the direction of movement of the center of gravity of the vowel triangle is statistically significantly forwarded and lowered in the chant method in both the word and the phrase context. The results also proved that accent is the most influential musical factor in chant. There was no significant difference between four repeated tokens, which increased the reliability of the results. In other words, chanting is an effective way to shift the center of gravity of the vowel triangle, which suggests that it can help to improve speech intelligibility by forming a desirable place for articulation.
