In this paper, I analyzed the cause that girl' ICT literacy score was hiegher than boy's score in middle school after 2010. KERIS had sampled 1% of whole middle school students and measured their ICT level. Therefore, I analyzed the correlation by gender between ICT literacy score and the using habit of ICT based on that result. As a result, the girl's score was higher than the boy's score in field of creating or editing documents, searching information for homework and study, accessing to on-line dictionary for study and enjoying SNS. Also, that difference between girl and boy had little correlation with ICT literacy score. Therefore, I proposed educational method for ICT literacy learning based on the difference of habit to use ICT between boys and girls.

The lack of research on the suitability of park green spaces as a form of earthquake shelter leads to difficultiesin highlighting the functions of these shelters. In this study, the weight value and priority of 27 indexes derived from previous studies are calculated by the AHP method and then a score table was established via a transformed score method. The final evaluation grade is divided into five levels: very inadequate, inadequate, general, adequate, highly adequate. Finally, indexes that were difficult to judge were explained. Based on this, the suitability evaluation of park green spaces as a form of earthquake shelter can be performed. The evaluation results can reflect the advantages and disadvantages of park green space as a form of earthquake shelter and indicate directionsfor construction in the future.

Most Web search engines use ranking methods that take both the relevancy and the importance of documents into consideration. The importance of a document denotes the degree of usefulness of the document to general users. One of the most successful methods for estimating the importance of a document has been Page-Rank algorithm which uses the hyperlink structure of the Web for the estimation. In this paper, we propose a new importance estimation algorithm for the blog environment. The proposed method, first, calculates the importance of each document using user's bookmark and click count. Then, the Guru point of a blogger is computed as the sum of all importance points of documents which he/she wrote. Finally, the guru points are reflected in document ranking again. Our experiments show that the proposed method has higher correlation coefficient than the traditional methods with respect to correct answers.

Most e-marketplaces build a reputation system that provides potential buyers with reputation scores of sellers in order for buyers to identify the sellers that are more reliable and trustworthy. The reputation scores are computed based on the aggregation of buyers' ratings. However, when these ratings are used to compute the reputation scores, the existing reputation systems do not make a distinction according to the following two criteria: the capability of the seller and the quality of an item. We claim that a reputation system needs to separate the two criteria in order to provide more precise information about the seller. In this paper, we propose a method to compute seller's reputation by separating the rating into the seller's score and the item's score. The proposed method computes the reputation of the seller's capability by using only the 'seller's score' and helps potential buyers to find reliable sellers who provide fast delivery and better service. In experiments, we propose a simulation strategy that reflects the real life of an E-marketplace and verify the effectiveness of our method by using the generated simulation data.

Recently, there has been continued research on UCP from the development effort estimation method to a software development project applying object oriented development methodology. Current research proposes a linear model estimating the developmenteffort by multiplying a constant to AUCP which applies technical and environmental factors. However, the fact that a non-linear regression model is more appropriate as the software size increases, the development period increases exponentially. In addition, in the UCP calculation process the occurrence of FP errors due to the application of TCF and EF, it is unrealistic to estimate the size with AUCP. This paper presents the issue of current research based on UCP without considering problems of the research, for example, TCF and EF and expresses the models (linear, logarithmic, polynomial, power and exponential type) estimating the development effort directly from UUCP. Consequently, the exponential model within non-linear models exhibit more accurate results than the current linear model. Therefore, after calculating the UUCP of the developing software system, using the proposed model to estimate the development effort, it is possible to estimate the direct cost required in development.

Geriatric depression is associated with pathological changes in the brain and increases the risk of cognitive impairment or dementia. However, high cognitive reserve, such as high education, can delay or minimize clinical manifestations of pathologies involving the brain, so the effect of geriatric depression on cognitive impairment or dementia may vary depending on the education level. In this study, the author analyzed data from the Korean Longitudinal Study of Aging (KLoSA) to examine whether the effect of geriatric depression on cognitive function differed depending on education level. Among the 10,254 subjects registered in the KLoSA, the 4,905 subjects who met the inclusion criteria were analyzed by stepwise regression analysis. The results were as follows: first, depressive symptoms predicted low cognitive function after 12 years; second, the negative effect of depressive symptoms on cognitive function after 12 years was higher in the old adult group than in the young adult group; and third, the effect of age was significant only in the low-educated group. These results suggest that depressive symptoms in low-educated old adults may increase the risk of development of dementia in the long term.

Use Case Point(UCP) is a measure of a software project size for software effort estimation based on use case. UCP measures the size of the software project based on the use case model. Because UCP is based on the use case model, it is intuitive and easy to obtain. Also, it does not require extra artifacts. On the other hand, UCP has some problems. UCP assumes every transaction has the same complexity. But, the number of operations and complexity of operations may affect complexity of transaction. In addition, UCP uses simple rating scale of complexity, but it may be inadequate for detailed estimates. To solve these problems, we suggest "Transaction Point(TP)", a size measure based on use case transaction. TP considers actors and operations in transaction. Complexity of transaction is based on the number of operations and complexity of operation, so it can support detailed estimation.

The purpose of the study is that which has to do with changes that are inherent in life or mental health of the local population, which appears as a subjective aspect of social capital of local residents. To examine factors that affect the mental health of the residents of a social capital accumulation and changes, as described a positive relationship between social capital in several previous studies related to the quality of life of local residents. The results showed that affect the mental health is the only community consciousness in 2010, higher community consciousness and higher network capacity of 2011 residents, but higher mental health scores, lower mental health scores were greater participation in social participation. Also score high in the mental health component of the group of the high number of people in all social capital and more social capital were higher than residents in low mental health score group. The indirect effects on mental health of the residents of social capital accumulation and changes.

This study was conducted to compare the evaluation scores among different evaluation agents-tutor, peer and self evaluation. It also aimed to identify the correlations among the evaluation agents and each agent's influencing factors that can have impact on PBL evaluation. 105 nursing students who had PBL methods in their learning had 3 different tutor, peer and self evaluation consecutively with the PBL Effectiveness Evaluation Tool. Self evaluation score was higher than both tutor and peer evaluation for 3 different evaluation. There was a significant correlation between tutor evaluation and peer evaluation. 'Problem solving ability' for tutor evaluation and 'Cooperative learning ability' for peer evaluation and self evaluation were the influencing factors.
