One of the important elements for improving academic achievement of learners in education through e-learning is to support learners to study by finding questions they want with providing various evaluation questions. However, most of question retrieval systems usually depend on keyword search based on only a syntactical analysis and/or a hierarchical browsing system classified by the topics of subjects. In such a system it is not easy to find integrative questions associated with each other. In order to improve this problem, in this paper we proposed a question management and retrieval system which allows users to easily manage questions and also to effectively find questions for study on the Web. Then, we implemented a system that gives to access questions for the domain of C language programming. The system makes it possible to easily search questions related to not only a single theme but also questions integrated by interrelationship between topics and questions. This is done by supporting to be able to retrieve questions according to conceptual interrelationships between questions from user query. Consequently, it is expected that the proposed system will provide learners to understand the basic theories and the concepts of the subjects as well as to improve the ability of comprehensive knowledge utilization and problem-solving.

This study explores the causes of online helping behavior. This study tests the effects of various explanatory factors on the basis of previous studies on helping behavior. These factors include social demographic, situational, motivational, and social capital factors. According to the survey of 475 university students living in Seoul in 2010, age and religion have significant effects on online helping behavior. In addition, the perceived helping opportunity, time and effort cost to help, and social capital factor have significant effects on online helping behavior. Results reveal that the effect of social capital factor is the largest among other variables. However, it is shown that the effects of benefit from helping, empathy, and personal norm are not statistically significant. It is also revealed that the effect of social capital factor is important across all types of online helping behavior except information helping. The policy implications are discussed.

A selection of the analysis section for traffic accidents is used to analyze definitely the cause of accidents sorting similar accidents by a group and to raise the effect of improvement projects deciding the priority of accidents. In the existing method, an uniformly dividing method based on road mileages has been used, which has no consideration for similarities among accidents. Consequently, in recent, a slider-length method considering accident types rather than road mileages is widely used. In this study, using K-mean method, a non-hierarchical grouping technique used in the Cluster Analysis ai a applicatory method for the slider length method, a method classifies accidents that occurred the most nearby mileages into one group is proposed. To verify the proposed method, a comparison between the f-mean method and the dividing method at regular intervals on the data of a total of 25.6km lengths along Kyung-bu freeway in Pusan direction was made so that the K-mean method was proved to an effective method considering the similarities and adjacencies of accidents.

The insistence of rights and interests in contract is being generalized by opening in construction market which is following F.T.A, internationally. Conditions of contract in construction have different specialities compared with other industries. Different conditions of contract should be established because of a specific character that is different from each construction, such as work, environment, circumference conditions. Although the order of Turn-key is being expanded by increasing construction scale and demanding hybrid function, the suitable regulations of contract are not settled. As a result, various factors of claim is occurring in Change Order-Claim, because they just obey a part of guide-line. This study suggests useful solutions in detail concerned with the main factor of Change Order-Claim by each D/B phases through practical sorting and analysis of the causes of Change Order-Claim.

This study applied following analysis methods and procedures to derive out characteristics of transitional garden culture. Analysis on socio-cultural characteristics in 1920s. Analysis on actual condition of transitional garden's design. In this point Outline of the Garden, Space formation, Garden designing elements are (1) water landscape, (2) plant, (3) structures, (4) paving, to derive out characteristics of the transitional garden. The results follow as below; First, during the transitional period 1920s, the economical development, fueled by opening nation's door to foreign countries and indication of collapse of statue systems together with idea of practical science and Enlightenment Thought, was element of changes in garden style. Second, Garden Designers of transitional gardens in 'Oeam-Ri' were limited to upper class of the society. They were wealthy enough to maintain their high social statue in rapidly changing society. As results, tendency of returning to nature developed gardens located in a site of scenic beauty and development of geographical features arranging techniques, and also showed copying foreign styles. Third, arrangement of garden and space composition, in most cases, composed of buildings and yards. Changes in water landscape features and garden spaces are centered to main-yard. Major changes of the garden spaces are water landscapes and plants that showing foreign influences. Fifth, scenic appearance techniques appears with dense garden space and emphasizing visual scenic view. Sixth, the characteristics of transitional garden design techniques are development of geographical feature arranging techniques, changes and mixture of the materials and garden types, emphasizing garden's decorative beauty, change of concept of yard within house into garden, changes from 'borrowing of landscapes' to 'selecting landscapes', changes of front garden from emptiness to fullness, changes of attitudes of enjoying gardens from 'staying calm in the garden' to 'moving or walking in the garden', changes to inner-oriented view, and changes from 'just watching and enjoying the nature' to 'enjoying specific objects'. This study is one of the efforts to restore the identity of Korean Traditional Garden by approaching and observing modern era which function as bridge between tradition and present day, and we observed transitional aspects of changes of traditional garden into modern garden. Hereafter, more studies will be needed to Modern Garden Design be recognized as part of Korean Garden Design History and these would be author's next assignment.

Objectives: This study was aimed at investigating the ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis and related factors. And we want to compare the ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis and related factors among the provinces. Methods: In order to compare, the data was referred to National health insurance center for affirming the insurance type of the dead. And age adjusted mortality rate of tuberculosis of each insurance type was analyzed by whole country and the provinces. Related factors of the provinces were gathered from public statistic books. We analysed correlation study between the ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis and related factors among the provinces. Results: Major findings were as follows 1. The ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis was 5.6. And the ratio was relatively high at 40-60 ages. 2. The ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis by the province was varying. And the factors that were financial independence, crowdedness, percent of people on medical aid, population size served by each public health center, number of hospital by a million peoples have correlated with increment of the ratio. Conclusions: As a consequence of tuberculosis control, the ratio was high. Thus this finding suggests that medical utilization and preventive behavior, environment of tuberculosis patient are under handicapped condition. Especially large cities like metropolitan area who have high financial independence, high population density, high percentage of medical aid peoples have high ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis. There is need for additional and systematic research on the attitude or tendency toward medical services(inc1uding preventive services) utilization of medical aid tuberculosis patients.
