This study aims to explore concepts of public interest and universal service which have been essential ideologies and policy goals, but which have been a the state of conceptual chaos so far. It sheds light upon three aspects : (1) the origins of public interest and universal service, (2) conceptual components of public interest and universal service, and (3) the implementation of public interest and universal service ideologies into policy. As a result of this analysis, it was found, firstly, that public interest of broadcasting originated from western countries, was rooted in the United States, and then spread all over the world later. After universal service was begun in the United States, it became a key ideology of information and telecommunication in European countries and other countries as well. Secondly, when examining the conceptual components, more differences were found than commonalities between these two concepts. The most conspicuous common point was universalism The concept of public interest includes not only universal service, but also connotes other components such as independence, diversity, quality, and locality which are related to content. Thirdly, when these two ideologies are implemented into policy, there Is a contrast. This study shows that the public interest ideology was realized into regulatory policies, while the universal service ideology was realized into supportive policies. In conclusion, this paper suggests more exact usage academically, showing the differences between the two concepts. This paper recommends an enforced legal duty of broadcasters to provide universal service when the current broadcasting law is revised.

In many intrusion detection applications, n-gram approach has been widely applied. However, n-gram approach has shown a few problems including unscalability and double counting of features. To address those problems, we applied n-gram augmented Naive Bayes with k-truncated suffix tree (k-TST) storage mechanism directly to classify intrusive sequences and compared performance with those of Naive Bayes and Support Vector Machines (SVM) with n-gram features by the experiments on host-based intrusion detection benchmark data sets. Experimental results on the University of New Mexico (UNM) benchmark data sets show that the n-gram augmented method, which solves the problem of independence violation that happens when n-gram features are directly applied to Naive Bayes (i.e. Naive Bayes with n-gram features), yields intrusion detectors with higher accuracy than those from Naive Bayes with n-gram features and shows comparable accuracy to those from SVM with n-gram features. For the scalable and efficient counting of n-gram features, we use k-truncated suffix tree mechanism for storing n-gram features. With the k-truncated suffix tree storage mechanism, we tested the performance of the classifiers up to 20-gram, which illustrates the scalability and accuracy of n-gram augmented Naive Bayes with k-truncated suffix tree storage mechanism.

In the paper we study key agreement schemes when a party needs to establish a session key with each of several parties, thus having multiple session keys. This situation can be represented by a graph, tailed a key graph, where a vertex represents a party and an edge represents a relation between two parties sharing a session key. graphs to establish all session keys corresponding to all edges in a key graph simultaneously in a single session. A key agreement protocol of a key graph is a natural extension of a two-party key agreement protocol. We propose a new key exchange model for key graphs which is an extension of a two-party key exchange model. using the so-called randomness re-use technique which re-uses random values to make session keys for different sessions, we suggest two efficient key agreement protocols for key graphs based on the decisional Diffie-Hellman assumption, and prove their securities in the key exchange model of key graphs. Our first scheme requires only a single round and provides key independence. Our second scheme requires two rounds and provides forward secrecy. Both are proven secure In the standard model. The suggested protocols are the first pairwise key agreement protocols and more efficient than a simple scheme which uses a two-party key exchange for each necessary key. Suppose that a user makes a session key with n other users, respectively. The simple scheme's computational cost and the length of the transmitted messages are increased by a factor of n. The suggested protocols's computational cost also depends on n, but the length of the transmitted messages are constant.

In principal, the original form of Eupchi landscape in Naepo reflects a traditional idea regarding direction as a connection with one's fortune and naturalization strategy of power. In reality, the weight for the landscape inside the castle town was distinct by locality according to the conditions of natural geographies and main function of the castle town. In other words, the traditional Eupchi landscape was shaped under the fixed principles but it was simultaneously reflecting the local temporality and spatiality. As Chosun Dynasty went under the Japanese colonization, Eupchi in the traditional period started to evolve into a modem city. That is to say, the traditional Eupchi as a political place became to change into the center of capital accumulation, stronghold of economy and education, and center of town beyond the function as a place for government and administration. Therefore, the process of change from the landscape of Eupchi to a modem city was a kind of revolution in the form and function, and it was also a very rapid rearrangement of social space. The disparate element of landscape and double social space worked as a vital inertial element in the urban structure of Naepo area until the post independence and evolution of landscape.

The purpose of this article is to analyse the military thought of Ferdinand Foch and to present its contemporary meanings. 1.Foch's life: Since 1871 to end of World War I, he acted as a military philosopher, battle field commander, and Supreme Commender of the Unified Forces so as to be judged as Clausewitz of the 20th century. 2. Historical Background of Foch's Activity Period : The series of the domestic revolutions after Napoleon's downfall were extended to Europe for independence, unification and overseas colonial wars. Thus Foch's growing and acting period was in totally imminent danger at all fields. 3. Foch's Military Thought : Through his three books, he argued cleary the absolute importance of the immaterial power including the technical esteem and the offensive fighting will for the victory. 4. The Contemporary Application of Foch's Thought : Though the operation plan based on Foch's strategic thought was defeated at the early stage of the World War I, its offensive-oriented immaterial spirit power should be remembered. 5. Conclusion : Foch's thought which develops the penetration through the war history and emphasizes the importance of the immaterial power should be highly appraised. Thus it should be also reinterpreted and redeveloped into a modern contemporary meaning.

Objective : This study verifies the effects of sensory integrative (SI) therapy on vestibular- and proprioceptive sensory (BPS) processing ability of a child with Asperger Syndrome (AS). Method : A boy who is 11 years and 2 months old took the Functional Independence Measure for Children (Wee-FIM), Canadian Occupational Performance Measure (COPM), Short Sensory Profile, Bruininks-Oserestky Test of Motor Proficiency-2 (BOT-2), and Test of Playfulness (ToP) for the baseline. The child participated in 3 evaluation sessions and 8 therapy sessions based on the AB research design. Duration of each session is 50 min and the therapy session is divided into 40 minutes for treatment and 10 minutes for evaluation. Since the vestibular sense and proprioception build up one's ability of postural control, several tests were employed to evaluate the child' postural control as outcome measure; distance from front leg of chair to heel of the child with sitting (C-H distance), angle between trunk and thigh (hip joint angle) with sitting, and the 'prone-extension posture' which is a subtest of Clinical Observation of Motor and Postural Skill (COMPS) to examine postural control embodied with integration of reflex and BPS processing. Result : During the therapy, average data of the C-H distance is decreased from 27.33cm to 11.69cm, average data of the hip joint angle is also decreased from $43.3^{\circ}$ to $20^{\circ}$, and average time for the prone-extension posture is increased from 13.15seconds to 24.84seconds. Conclusion : This result indicates that the ability to postural control in sitting and to maintain the prone-extension posture can be improved by sensory integrative therapy, with enhanced BPS processing.

Korea-Africa relations date back to the period of independence of African countries. During this time, the ties between Korea and Africa has passed through stagnation, inconsistencies and weak diplomatic exchanges. Recently, Korea began to refocus its efforts towards Africa in order to revitalize their relations. This paper examines Korea's public diplomacy strategies towards Africa and how its various strategies are working in the interest of Korea as well as Africa. The study shows that Korea's renewed interest in Africa is primarily driven by the security threat from North Korea and the need to diversify its market for industrial goods as well as energy sources. The latter motives override Korea's interest in the continent. These motives are not at variance with those pursued by large powers like the US and China in Africa. Furthermore, the paper shows that Korea is employing a mixture of public diplomacy instruments in Africa with varied outcomes. Economic linkages between Korea and Africa are on an upward trajectory since the late 2000s. In order to build sustainable relations, the paper provides a number suggestions with far-reaching implications on Korea's public diplomacy towards Africa in the future.

Background:The dopaminergic genes have been implicated with some personality traits. Many recent studies indicated that there is a correlation between D2 dopamine receptor gene(DRD2) polymorphisms and the personality traits. The purpose of this study is to investigate a possible association between DRD2 gene (TaqI A, TaqI B) polymorphism and personality traits. Methods:The subjects were consisted of 173 blood-unrelated young female Koreans with a mean age(${\pm}SD$) of 13.88(${\pm}0.29$) years. These volunteers were recruited from one of the junior high schools in Seoul and were tested by the Korean version of the Temperament and Character Inventory(TCI). Genotyping of the DRD2 polymorphisms by PCR methods were carried out. Two DRD2 gene polymorphisms were classified and individually assessed as follows:TaqI A1+ vs A1-, TaqI B1+ vs B-. The associations between the TCI scores and TaqI A, TaqI B polymorphisms were assessed by Student's t-test. Results:In the 173 subjects, the allele frequencies of the DRD2 TaqI A1, TaqI B1 alleles ranged from 0.42 to 0.43, and these results are quite different from the ranges of 0.15-0.20 in the case of a Caucasian population. The genotype frequencies of DRD2(TaqI A1, TaqI B1) variants showed no significant deviation from the Hardy-Weinberg equilibrium. RD4(dependence vs. independence) of Cloninger's TCI, a sub-dimension of Reward Dependence, was significantly higher in the subjects having DRD2 less frequent alleles than those without these alleles. Conclusion:This study suggests that the female subjects carrying the less frequent DRD2 alleles exhibited higher reward-dependent personality trait compared to those without these alleles.

The role and importance of entrepreneurship is fast becoming recognized with the topic of creative economy in Korea. Especially, young generations having difficulties of finding a job choose to be an entrepreneur as a part of their career choice due to the changes in social awareness about entrepreneurship and the increase of entrepreneurship education opportunity. It is needed to approach with the analysis of young people's career choice reasons in order to provide effective entrepreneurship education to those who has the choice of career ahead. Each student has different desire to entrepreneurship lecture and education with the basis of their own motivation and goal of career choice reasons. The objective of this study is to examine career choice reasons with 1,651 science and engineering field students in universities to determine the sustainable needs of entrepreneurship education. As a result of the analysis, there is significant relationship between the satisfaction of entrepreneurship education and the intrinsic factors such as self-realization, innovativeness, role-model and independence. In addition, the satisfaction of entrepreneurship education is significantly related to the sustainable desire of entrepreneurship education. In other words, it is needed to enhance intrinsic value of the students' career choice reasons for sustainable entrepreneurship education due to successful start-ups requiring to have information and understanding process of business which comes from continuous entrepreneurship education.

The purpose of this research is to investigate the determinants of life satisfaction and social support among the elderly. For this purpose, a set of characteristic factors that are supposed to affect elderly life satisfaction were suggested and empirically analyzed. To achieve this study used final analysis with 470 questionnaires which did a questionnaire survey after gathering purposeful sampling method of 500 person who were visiting on Senior Club and Senior Welfare Center. The collected data were analyzed by using the SPSS statistical program. The methods of analysis were frequency, factor analysis, and regression analysis. The results of this study are as follows. Firstly, characteristic factors such as the family relation, health and economic of the elderly have significant impacts on their life satisfaction. Secondly, it was seen that social support regulated the effects of family relation and economic on characteristic factors. The implications of this study are, above all, to build a human network for training, education and social support for career development while participating in the labor market. Such activities could lead to social support for economic independence in old age.
