Personal time perspective is a factor influencing motivation and goal-oriented behavior. The start-up process is a preparatory process for the future rather than the present. There will be a difference in entrepreneurial decision making depending on the level of time perspective. This study verified the relationship between individual 's time perspective and entrepreneurial self-efficacy. For this study, a survey was conducted with 190 students in college. To test the hypothesis, t-test, one-way analysis of variance and correlation analysis were used. The results of the study are as follows. First, we analyzed the difference of individual 's time by past-negative, past-positive, present-fatalistic, present-hedonistic, and future-oriented time. As a result of analysis, the more experience of entrepreneurship education, the higher the present-fatalistic, present-hedonistic, and future-oriented level. Second, the effect of individual's time perspective on entrepreneurial self-efficacy was analyzed. The past-negative and present-fatalistic level influenced negative on entrepreneurial self-efficacy. The present-hedonistic and future-oriented level influenced positive on entrepreneurial self-efficacy. Finally, based on the above results, academic significance, implications and limitations are suggested.

Among many factors that affect the development of the talent of gifted children, the family factor that first finds and cultivates the talent of gifted children is quite important. The researches on the family of gifted children are mostly concentrated on physical environment out of the home environment, neglecting psychological environment. Although the recreational activity of family with gifted children considerably contributes to the emotional, intellectual and social development of gifted children themselves and to the improvement of life quality of the family members, the recreation of family with gifted children has not yet been studied. Thus, the objective of this research is to present basic materials for seeking the direction to educate parents and to support family with gifted children in order to encourage synergy effect in emotional and social growth of family with gifted children by surveying the property of recreation of family with gifted children. The result of result is as follows. First, the type of family with gifted children tends to be remarkably biased to 'family-oriented activity' and 'elf-development activity.' Second, verifying the significant level of motive for recreational activity of family with gifted children at the variables such as number of family members, parents' age, parents' education level, parents' occupation, etc, it was concluded that they were not statistically significant.

The idea that parental involvement has a positive influence on gifted children is so intuitively appearing that society in general. and educators in particular, have considered parental involvement as the remedy for many problems in education. However the vast proportion of the literatures in this area give results qualitatively. Among the empirical studies that have investigated this issue quantitatively, there appear to be considerable inconsistencies. A meta-analysis was conducted to synthesize the quantitative literatures about the relationship between parental involvement and gifted development. The findings reveal a moderate relationship between parental involvement and gifted development. We focused on the effect between parental involvement and gifted development, and conducted meta-analysis involving correlation coefficients between the two constructs. Using correlation coefficients, We can get the effect size, and explain the influence. We initially identified 539 articles over twelve-year period. Based on abstracts of these 539 articles, 463 studies were used for analyzing the current stream of the study. Finally, 15 studies met our inclusion criteria, and were subsequently used in this meta-analysis. From the 15 studies, 37 variables influenced on gifted development were collected. Using meta-analysis, it is revealed that internal effects for gifted development have stronger relationship than parents' socioeconomic status. In addition, the differences between female and male student have been reducing.

The rapid development of computer network technology has brought the Internet as the major infrastructure to our society. But the rapid increase in malicious computer intrusions using such technology causes urgent problems of protecting our information society. The recent trends of the intrusions reflect that the intruders do not break into victim host directly and do some malicious behaviors. Rather, they tend to use some automated intrusion tools to penetrate systems. Most of the unknown types of the intrusions are caused by using such tools, with some minor modifications. These tools are mostly similar to the Previous ones, and the results of using such tools remain the same as in common patterns. In this paper, we are describing design and implementation of attacker-traceback system, which traces the intruder based on the multi-agent architecture. The system first applied SOM to classify the unknown types of the intrusion into previous similar intrusion classes. And during the intrusion analysis stage, we formalized the patterns of the tools as a knowledge base. Based on the patterns, the agent system gets activated, and the automatic tracing of the intrusion routes begins through the previous attacked host, by finding some intrusion evidences on the attacked system.

A pavilion is located in the place with beautiful scenery, which maximizes the poetical features of nature. So a scholar in the Chosun Dynasty had the dream of possessing it. This trends of the Chosun scholar resulted in producing lots of literary works related with the pavilion. In this thesis, I researched the characters of Pavilion Si-Jo in accordance with the function of pavilion. First, the pavilion, which is surrounded by the beautiful scenery, is a good place to see the beauty of nature. It is needless to walk around to see the scenery thanks to its open structure. So the feeling in the pavilion Si-Jo is distinguished from other sightseeing Si-Jos: those show the way of seeing the scenery walking here and there, but this shows the way of seeing the scenery only just looking up, looking down, and looking in the distance. Second, the pavilion functions as an academic place. In this case, it can be said that it functions like a lecture hall. It is more effective to study in the pavilion than in the closed structure, a lecture hall. Furthermore, the scholar studying in the pavilion understand the principle of nature with seeing the beautiful mountain and river, and it can be a place for growing a vast-flowing spirit. This kind of poetry has been handed down with the Chinese poetry, and the character who operated the pavilion often appears in the work. Third, the pavilion functions as a space for a fraternity or poetry circles. The poetic exchange was conducted by host of pavilion. which is the key ingredient for organizing a poetry circles. Finally, the pavilion functions as an entertainment. Although it is a space for an entertainment, there is no deviation as a man of novel birth. If the pavilion has the feature of closeness, there are sometimes works which shows the deviation of them.

In democracy basic rights such as political equality and participation through elections have been respected, opportunities of corporation and opposition have been guaranteed, and ability of self-learning and self-correction have been developed. These positive factors give preconditions for the welfare development in the democratic state. Because in this state adults get the suffrage and the open competition for official positions induces political parties use social policies as means to win the election. That is to say, political parties have an incentive to use various social policies to win the election. Democracy, therefore, has affinity with social policy. The affinity between democracy and social policy can be found also in Korea which was democratized in 1987. But, in Korea, the positive relationship between democracy and social policy is very weak due to the problem of constitutional structures. Korean Parliament usually enacts abstract social act and delegates the right to fill concrete contents of the social acts to the executive. Delegation itself has no problem, but excessive delegation is a problem since the executive can overuse its discretion as sacrificing the social rights of the citizen. In addition social consensus could not be achieved in this constitutional structures, which are a obstacle to establishing a political process in the Parliament to promote the welfare development through party competition. Excessive delegation should be reduced, and the Parliament should fill concrete contents of the social acts as exercising its legislative power more. Then a mechanism of welfare development can be launched in Korea.

This paper describes a Delay Locked Loop (DLL) with low supply voltage and wide lock range for Synchronous DRAM which employs Double Data Rate (DDR) technique for faster data transmission. To obtain high resolution and fast lock-on time, a new type of phase detector is designed. The new counter and lock indicator structure are suggested based on the Dual-clock dual-data Flip Flop (DCDD FF). The DCDD FF reduces the size of counter and lock indicator by about 70%. The delay line is composed of coarse and fine units. By the use of fast phase detector, the coarse delay line can detect minute phase difference of 0.2 nsec and below. Aided further by the new type of 3-step vernier fine delay line, this DLL circuit achieves unprecedented timing resolution of 25psec. This DLL spans wide locking range from 500MHz to 500MHz and generates high-speed clocks with fast lock-on time of less than 5 clocks. When designed using 0.25 um CMOS technology with 1.8V supply voltage, the circuit consumes 32mA at 500MHz locked condition. This circuit can be also used for other applications as well, such as synchronization of high frequency communication systems.
