  • Imported China Jades are mostly talc and serpentine groups, and that's occured troubles for our health and life of living organism. Serpentine is a group of common rock-forming minerals having the formula:(Mg$.$Fe)$^3$Si$_2$O$\_$5/(OH)$_4$. Sometime, simulated by nephrite or jade and translucent varieties we used for ornamental and decorative purposes. But it's forbid by heating materials for sauna and heating mats etc. that reason are it's occured asbestos dusts(chrysotile dusts) easily by the beating operations.

  • A graphic user interface for effectively browsing object-oriented databases in complex applications is designed and implemented. The rationale behind our design lies in enabling the users of various levels and needs to investigate the database according to their respective interests and desired depths. A novel idea in our design is the introduction of zooming techniques from a logical view, which vidualize the backbone abstraction concepts of the object-oriented data model. These objectives are verified by evaluating the results of its implementation.

  • The database design for the management of bridge measurement information is presented in this paper. To express the associated data generated during the whole process of ambient measurement efficiently, requirements analysis for database construction is performed. And to define objects and organize schema conceptual and logical design are performed, which convert data model into logical schema. Finally, physical design is performed using DDL(data defined language). This database is based on the object-relational data modeling approach that has rich expressive power and good reusability in comparison with the traditional entity-relational modeling.

  • Video On Demand servers generally require massive disk storages for storing many video data. Many researches have been done on the topics of efficient allocation of movies in disks. This paper, We describe efficient disk placement techniques and implement storage system with SCSI and PCI Bus interface for efficient data handling. This paper also proposes a logical zone reconstruction method for the SCAN data placement technique. The proposed method reconstructs physical zones into logical zones by split and merge operations.

  • The writer has made efforts to solve the weaknesses of the traditional systems through reconstructing cost information systems by introducing 'logical circuit concept' instead of account. As the new designed systems also allow the basic thought of double entry, they are compatiable with the traditional ones. For this, the writer included both monetary and physical information in the systems, replaced the concept of debit & credit with the concept of inputs & outputs, and changed transfer concept between accounts based on reverse logic into flow concept between unit systems based on proceeding logic.

  • This study is aimed at developing the systematic application of logic in composition of architectural space. It is investigated in the logical concept and its development applied to the rule of composition. Applying the method to the architectural composition. it is focused on modeling to the systematic approach in architectural composition. Therefore this study is investigated in the design process on the viewpoint of the systematic approach considering diverse variables. and it is accomplished to logical composition in architectural space. Being more studied. this method is applied to the composition of architect ureal space and practice.

  • This paper show Device Driver for RTOS-FT Systems. In this paper, a definition of Device Driver is introduced which is used in RTOS-FT Systems. The structure of Device Driver is briefly divided into physical layer and logical layer. The specific characteristic of Physical Held and logical field which is discussed in this paper is suggested for the system which is satisfied with fault-tolerant theory.

  • Implementing the linguistic theories on computer, we resolve the problems for restrictions of computer and increase processing efficiency for systemization not for linguistic theory itself. Thus, we modify the grammatical theory to be applied to systems. This paper reports the various problems about constructing dictionaies, defining rules, and appling universal principles and metarules, which is caused to implement the systems based on GPSG. In semantic interpretations, logical expressions which correspond Montague grammar are acquired, and we make a rule connect with several logical expressions. And we show the efficiency of the this method through implementing parser.

  • This study has purpose on analyzing the error types which are identified after middle and high school students perform the online programming assignments and also has the purpose on the analysis of correlation between the frequency of error occurrence according to academic achievement level in programming concept learning and types of errors analyzed previously. For this study, the syntax, logical, and coding errors are analyzed from the performed results of programming research assignment for 88 students. Analyzed results show that the logical error has the highest occurrence rate of 69.3% among three types of errors, and it has been shown meaningful difference in the frequency of error occurrence between three achievement level groups of high, middle, and low. In the correlation analysis of achievement level and error types, it shows negative relationship between logical error and coding error, and therefore it can be concluded that as achievement level is higher, both logical and coding errors tend to occur less. In the correlation analysis in error types, it shows positive relationship between syntax error and coding error.
