This reach is to comprehend the trend of father-related studies in Korea. The result of analyzing 161 father related thesis published from first issue until 2015.12 issue on 9 journals came out as below. First, father-thesis have increased. But the proportion of it remains for only 1~2% out of total 9 academic journals. Also the increased amount is very small considering the increasing rate of mother-thesis. In other words, the increased number of father-thesis is due to increased number of total amount of academic journals, which cannot be interpreted as the academic interest about fathering has grown. Second, almost of father-thesis were the empirical research and quantitative approach took the most part. Also father-thesis focus on 'what father's role is' and 'how much he does it'. Due to generalization of double-income family and an increase of interest about fathering, operational definition and a measurement issue is growing. Third, the topic of research which handles influence of father to child ranges from social relationship to social and emotional development. Also an interest of awarness development is growing. Meanwhile, research of father's influence to child development depends on cross-sectional data. Only few used vertical material.

The essay examines the development and characteristics of regionalism as new social-political conflicts in Western Europe since 1970's and explores theoretical approaches of regionalism in terms of modemization theory of social sciences. There are various types of regionalistic movements: separatism, regional equity development, federalism, autonomy, nationalism, and so on. These different orientations have already shown serious problems, theoretical and conceptional, conceming the analysis of regionalism. But in conceptualizing this phenomenon, five competitive theses could be distinguished: persistence thesis, differentiation thesis, political procedure thesis, convergence thesis, and counter-differentiation thesis. Although the heuristic theses are still elaborated on the base of empirical studies and actual data, they indicate that each thesis ontologises the region as one of the key concepts explaining regionalism very differently.

The first part of this thesis discusses the types and the properties of errors, one of which makes up systematic errors of measurements, removable by detecting their causes, the other errors of accidental causes which can not be removed. The final part of this thesis deals with the historical background of the Gaussian distribution by Hershel, Hagen, Laplace and Gauss from the late 18th century to the early 19th century. It can be concluded that the accidental idea and the treatment of accidental error distribution by Gauss Is the best one based on the assumption that the most probable value of true value is the arithmetic mean of data, obtained by repeated measurements of a given quantity.

In this thesis was conducted to propose a method for efficient information retrieval using concept lattices. Since this thesis designed a new system based on ordinary concept lattices, it has the same approach method as ontology, but this thesis proposes new concept lattices to be used by establishing collaborative relations between objects and concepts that users are likely to search information more efficiently. The system suggested by this thesis can be summarized as below. Firstly, this system leads to a collaborative search by using Three kinds of concepts, such as keyword concept lattices, which focus on input key words, expert concept lattices recommended by experts and theme concept lattices, and based on these 3 concept lattices, it will help users search information they want more efficiently. Besides, as the expert concept and the keyword concept become combined, further providing users with the frequency of keyword and the frequency of category, this system can function to recommend key words related to search words entered by users. Another function of this system is to inform users of key words and categories used in users' interested themes by using the theme concept lattices. Secondly, when there is not keyword entered by a user, it is possible for users to achieve the goal of search through the secondary search when this system provides them with key words related to the input keyword. Thirdly, since most of the information is managed while being dispersed, such dispersed and managed information not only has different expression methods but changes as time goes. Accordingly, By using XMDR for efficient data access and integration of distributed information, this thesis proposes a new technique and retrieval system to integrate dispersed data.
