Concrete structures in the marine environment often deteriorate in the early stage of their service life because of contact with various aggressive conditions. In recent years, the study on the concrete in the marine environment are carried out to increase their service life. In this experimental study, the concrete specimens were prepared with various adding contents of inorganic antifouling agent$(0\~3.0wt\%)$ composed to some fluosilicate solution. For evaluatin of the physical and chemical properties of concretes containing inorganic antifouling agent, various tests such as setting time, slump loss, compressive strength, water absorption rate, freezing and thawing resistance and SEM micrographs of concrete, were conducted. As the results, physical and chemical properties of concretes were improved with an adding of inorganic antifouling agent. From the results of various tests, the optimal adding contents of antifouling agent was $1.0wt\%$.

In ubiquitous environments, the content adaptable services can be dynamically provided to adapt the frequent changes of contexts. These services have common things that the kinds of context factors are limited to ubiquitous environment, though the contexts are flexible. To reuse service architecture can be reasonable for effective adaptable service. In this paper, we design a software architecture with product line techniques for content adaptable applications in ubiquitous environment. Description of product line is to define variation points and their variants, to find out the dependencies between them and to keep the model based architecture, their alternatives.

The purpose of this study was to examine the cause of new curriculum which has always problems even though it is revised repeatedly and to propose an fundamental alternatives to solve these problems. In this study, the cause of these problems considered the wrong point grasping the knowledge of curriculum contents. In other words, the knowledge of curriculum contents is understood as the point of utility rather than the curriculum are constructed as the form reflecting nature of knowledge. According to do this, Bruner's structure of knowledge is of help. The structure of knowledge which is well known existing is understood as manifest aspect but from now on, we have to be concerned about tacit aspect. In this case, the structure of knowledge has characteristics as an integrated knowledge.

The purposes of this study were to compare and analyze the local primary textbooks for the subject of 'We are the First Graders'. This study analyzed the common points and the differences among three textbooks developed by the three educational bureaus of Seoul, Daegu and Busan. The criterion of analysis were scope, sequence and integration of curriculum representing the principles for developing curriculum. The results were as follows: First, the scopes of topics included in 2007 National Curriculum of 'We are the First Graders' were faithfully reflected in the three local textbooks. Second, the sequences of textbooks were generally arranged according to the order of curriculum content except for some contents. As for 'Wise School Life', some contents were presented at the first unit of the three textbooks and the others were gradually expanded at the latter of the textbooks. Third, the integration of curriculum appeared meaningfully in the three textbooks. Based on these results, this study suggested some recommendations on the activites for the adaptation at the early stage in the primary school under 2009 National Curriculum.

Eight chlorobenzenes (out of a total of 12 in the congener series) were measured in the sediments from 21 stations in the southeastern coastal areas of Korea. The levels of total chlorobenzene isomers varied between 2.08 and 12.45 ng/g dry weight. The highest contents of total chlorobenzenes (CBs) were found in the sediments from Pohang coast. Trichloro­benzenes (the sum of 1,3,5-, 1,2,4- and 1,2,3-trichlorobenzene) were dominant classes among four congeners, whereas tetrachlorobenzenes (the sum of 1,2,3,5-, 1,2,4,5- and 1,2,3,4-tetra­chlorobenzene) and pentachlorobenzene were low levels. The contributions of total CBs showed similar patterns for all stations with positive significant correlation within CBs species. It means that CBs contamination in the southeastern coasts of Korea came from the similar source.
