This study was conducted to predict future land-cover changes under climate change scenarios and to cluster analysis of regional land-cover characteristics. To simulate the future land-cover according to climate change scenarios - A1B, A2, and B1 of the Special Report on Emissions Scenarios (SRES), Dyna-CLUE (Conversion of Land Use Change and its Effects) was applied for modeling of competition among land-use types in relation with socioeconomic and biophysical driving factors. Gyeonggi-do were selected as study areas. The simulation results from 2010 to 2040 suggested future land-cover changes under the scenario conditions. All scenarios resulted in a gradual decrease in paddy area, while upland area continuously increased. A1B scenario showed the highest increase in built-up area, but all scenarios showed only slight changes in forest area. As a result of cluster analysis with the land-cover component scores, 31 si/gun in Gyeonggi-do were classified into three clusters. This approach is expected to be useful for evaluating and simulating land-use changes in relation to development constraints and scenarios. The results could be used as fundamental basis for providing policy direction by considering regional land-cover characteristics.

This study was conducted to examine the relationships among various visible clues and non-visible clues as perceived by franchise family restaurant consumers. Using online survey tool in South Korea, total 450 survey was distributed and 400 participants were used for further statistical analysing with SPSS 23.0 and AMOS 20.0. Twelve items were categorized into four visible factors (food, interior, exterior, employee). The result shows that food and employee have positive effects on brand reputation and distinctiveness, and the interior and employee were critical antecedents for brand distinctiveness. In addition, the brand reputation and brand distinctiveness have positive influence on experiential value as well as revisit intention. Although there were many studies which demonstrated the relationships among various quality clues and other outcome variables, such as brand image, loyalty, little research explained the relationships among visible elements of franchise family restaurants, brand reputation, brand distinctiveness, and revisit intention. The present study will provide theoretical and practical implications for both academia and the franchise family restaurant industry. (what is the meaning of the red part?)

This study examines whether there are differences in consumer's evaluation price zone on the clothing clue (the type of clothing, brand, time of fashion, place of origin, material. submaterial, place for sale) according to consumer purchasing behavior. Therefore the ultimate goal is to offer help in fixing price when establishing marketing of the clothing industry by grasping the actual price set by consumers under the IMP system. The female consumers of 20s and 30s were chosen as study subjects for their sensitivity to the purchase of clothing. The tests carried out in this research are: SPSSIPC+ is used for frequency Analysis. The Results of this study are showed as the following: It was analyzed that 4 types of consumer are the reasonable consumption oriented consumer, fashion oriented consumer, the no care of fashion consumer and high price oriented consumer Among the several kinds such as the type of clothing, brand, time of fashion, place of origin, material, submaterial, place for sale, only on the type of clothing, there are difference in the type of the consumers, on the time of buying clothes, in the behavior of buying clothes and also on the degree of fashion and the place of origin among such kinds.

The emergence of E-book have allowed readers to interact with other readers and to actively participate (e.g. social reading). Furthermore, there is a growing demand in writer's community to take the advantage of the feedback from their readers to update the content of E-book. To do that, they require the service that utilizes the user feedback while creating or updating the e-book content. This study aims to let authors collect and to apply the reader's feedback on E-book content. However, in order to apply the user feedback, users first need to explicitly type the feedback, and even if they do, authors need to develop the software to automatically analyze and to apply the user feedback. This makes difficult for authors without programming background to produce E-book with automatic content adaptation. In this paper, we propose Feedback Clue Model to generate, analyze and apply the user feedback into E-book content. Based on this model, we develop the block editor which allows easy implementation of E-book that can be dynamically updated.

In contrast to well-known imaging findings of intracranial epidermoid cysts on magnetic resonance imaging, those of intracranial squamous cell carcinoma (SqCC) are relatively unknown. We present a case of coexistence of intracranial SqCC and epidermoid cyst, with consecutive follow up over 14 months. Based on our case, a solid enhancing portion adjacent to a typically-looking epidermoid cyst may become a clue for coexistence of intracranial SqCC. An initial contrast enhancement and/or heterogeneous signal on diffusion weighted imaging may become a useful diagnostic clue, but more importantly, sudden rapid growth is important in formulating diagnosis.

This paper makes a close inquiry into ill-conditioning that may be occurred in wireless localization of the sensor nodes based on network signals in the wireless sensor network and provides the clue for solving the problem. In order to estimate the location of a node based on the range information calculated using the signal propagation time, LS (Least Squares) method is usually used. The LS method estimates the solution that makes the squared estimation error minimal. When a nonlinear function is used for the wireless localization, ILS (Iterative Least Squares) method is used. The ILS method process the LS method iteratively after linearizing the nonlinear function at the initial nominal point. This method, however, has a problem that the final solution may converge into a LM (Local Minimum) instead of a GM (Global Minimum) according to the deployment of the fixed nodes and the initial nominal point. The conditions that cause the problem are explained and an adaptive method is presented to solve it, in this paper. It can be expected that the stable location solution can be provided in implementation of the wireless localization methods based on the results of this paper.

This study defines attributes of the Korean costume culture, focussed on hair, shoes and accessories which express sex-roles, encapsulated in the term, “be like...”. A group of 362 male and female university students from Seoul and Gyeonggi area was surveyed for the study. The statistical analysis of SPSS 10.0 was applied for analyzing the data, and the significant variances were reviewed by the basic statistics and t-test. The results are as follows; First, short hair is perceived as the typical hair style that symbolizes male, both from male and female university students. Hair colors in warm color such as brown, wine, purple, lemon and orange, and the style of hair such as bobbed, long, and perm are perceived as definite clues that symbolized female. Second, when it concerns the types of shoes, both male and female university students cited oxford as the typical clue that symbolizes male, whereas pumps and sandal were cited for female. Third, in terms of types of accessories, both male and female university students perceived necklace, earring, bracelet, hair pin and band, scarf, and muffler as very feminine. Among these, hair pin and band, and scarf are evaluated as the typical clues that signify the role of females. Necktie is perceived as the typical clue that signify male role.

A self-replicating RNA ligase ribozyme was converted to a cross-catalytic format whereby two ribozymes direct each other's synthesis from a total of four component substrates. Each ribozyme binds two RNA substrates and catalyzes their ligation to form the opposing ribozyme. The two ribozymes are not perfectly complementary, as is the case for replicating nucleic acid genomes in biology. Rather, the ribozymes contain both template elements, which are complementary, and catalytic elements, which are identical. The specificity of the template interactions allows the cross-catalytic pathway to dominate over all other reaction pathways. In the presence of $2{\mu}M$ each of the corresponding substrates, one ribozyme catalyzes the synthesis of the second ribozyme with an initial rate of $6.8{\times}10^{-3}\;min^{-1}$, while the second ribozyme catalyzes the synthesis of the first with an initial rate of $2.9{\times}10^{-3}min{-1}$. As the concentration of the two ribozymes increases, the rate of formation of additional ribozyme molecules increases, consistent with the overall autocatalytic behavior of the reaction system. Here, I present results that possibly demonstrate a clue for a self-replicating molecule by showing an RNA ligase ribozyme, which is reminiscent of 'Prebiotic Era'.

Quantification of carbon absorption and understanding the human induced land use changes forms one of the major study with respect to global climatic changes. An attempt study has been made to quantify the carbon absorption by land use changes through remote sensing technology. However, it focused on past carbon absorption changes. So prediction of future carbon absorption changes is insufficient. This study simulated land use change using the Conversion of Land Use and its Effects at Small regional extent (CLUE-S) model and predicted future changes in carbon absorption considering climate change scenarios 4.5 and 8.5 of the Representative Concentration Pathways (RCP). Results of this study, in the RCP 4.5 scenarios there predicted to be loss of 7.92% of carbon absorption, but in the RCP 8.5 scenarios was 13.02%. Therefore, the approach used in this study is expected to enable exploration of future carbon absorption change considering other climate change scenarios.

Six sigma is much less of a technical program than it is a leadership and cultural change program. Nevertheless, most of literatures on six sigma have mainly focused on technical and tactical aspects. This paper introduces a self-assessment for six sigma initiative in a major Korean software company. The self-assessment gives a valuable clue to how to manage leadership and cultural aspects of six sigma initiative.
