Osteoblastoma is an uncommon lesion of bone that occurred in jaw bone. The etiology of the Osteoblastoma is still undiscovered. The most frequent symptom is consistent pain which is often severe, and localized swelling and bone expansion mat occur. We experienced a case of osteo-blastoma which occurred on the lingual surface of mandibular body. It resembled tours mandibularis clinically, alveolar abscess radiologically. Biopsy was done to evaluable the tours-like bony mass. The results of excisional biopsy demonstrated an osteoblastoma. The symptoms are subsided and no signs related with recurrence have been noted. Our experience and many literatures demonstrated that Osteoblastoma must be included in differential diagnosis of bone-producing lesion.

The purpose of this study is to understand the parent's social cognition about disciplines in the context of korean culture by analyzing and interpretating theories of discipline and conceptions of parental role in disciplining children presented in the books for domestic life educatio of the chosen Dynasty period. The method used for this study is the historical method and the literatures of analysis are Naihun, Gyubeomseonyoung, Sasojol, Jongbo-Salimgyoungjai, Hahagjinam. Accoding to analysis, the disciplinary theory for children had the basis on the ideas that children learned through everyday expieriences and observation of surounding events, and that crytical periods of learning were at the early childhood. And parents assumed the responsibility for disciplining their children. Also the Chosen Dynasty period had the conceptions that parents had rigorous quality as well as warm-hearted toward their children and teached honor, modesty, plainess and industry.

The purpose of this study is to analyze typologic methods in the Family Studies. For this goal, we reviewed literatures related to social research methodology, and analyzed articles in the Family Studies part on the basis of themes and typologic methods. The major resets can be summarized as follow: Typology methods used to clarify complex and subtle family phenomena and distinguish redundant interaction in everyday life. Especially, they can show family system type, communication mode style, leisure activity type, life altitude type, and personality traits type. Typology was made by the methods as follow: the insight, crossing the two single question, intersecting scale's mean or middle point, cluster analysis, and factor analysis. Typology is useful method in the Family Studies, but the accuracy standard needs in the future studies.

This study emphasizes the everyday life study based on the proper study method. From the sociological literatures, everyday life's concept, it's various characteristics, two different perspectives and life-history approach are introduced. One Home Economics Paradigm Study published in 1996 is summarized to point out the importance of paradigm shift from quantitative method based on positivism to qualitative study for human everyday life study. I examined our everyday life studies as a reader and a member of screening committee and introduced four articles using different qualitative study methods.

Photosynthetically Active Radiation (PAR) affects the growth of plants as well as their photosynthetic rates. A mathematical model for intercepted solar radiation on the tilted leaf with any azimuth angle was established and the leaf orientation in which receives the maximum solar radiation was determined each month, during the growing season, and for an year. PAR was maximized at the leaf elevation of 50。~60。 in the winter, at that of 20。~40。. On the whole the leaves of tilt angle 0。~40。 received much radiation comparing with those of other tilt angles. The theoretical tendencies were compared with the distribution of leaf orientation measused practically. The average leaf elevation of maple tree was 17.0。$\pm$12.0。, and that of ginkgo was 29.8。$\pm$16.0。. Several results from other literatures support our suggestion that cumulative effevct of the relationships between surface normal vector and a vector pointing in the direction of the radiation determine the leaf orientation.

Tarsal tunnel syndrome caused by space occupying lesion is unusual but it rarely occur by ganglion which is presented below the flexor retinaculum due to compression neuropathy of posterior tibial nerve and its branches. The object of the current study is to report our experience of surgical treatment about tarsal tunnel syndrome caused by the ganglion of flexor digitorum longus tendon sheath and multifocal myxoid degeneration of medial plantar nerve with a review of the literatures.

Sialolithiasis is the common pathology of salivary gland. The size of sialoliths vary from 1 mm to a few cm, but most of that are less than 10 mm. Large sialoliths (larger than 15 mm) are extremely rare. It is called Giant sialolithiasis or megalith. Symptom of the giant sialolithiasis is similar to that of regular sialolithiasis. First choice of treatment is removal of the stone. Many literatures reported various methods to remove the sialoliths. For this case report, we accidentally found the giant sialolith on the computed tomography taken for dental implant, and successfully removed the stone by minimal invasive surgical approach. Base on this result, we report this case with literature reviews.

This study purports to contribute to existing literatures and debates about the future of Korean public pension system by introducing the cases of pension privatization in eight Latin American countries. Following the Chilean reform in 1981, many Latin American nations to a varying degree replaced their public pension system with private one, and the performance of those private systems started to emerge. Overall, pension privatization does not appear to be the panacea that some of its advocates have argued. While it seems to remedy existing problems, it is creating new ones. As an unprecedented policy experiment, the pension privatization in many Latin American countries implies that there are a number of risks in the path of privatization.

The main reason for deinterlacing is frame-rate conversion. The other reason for deinterlacing is of course improve clarity and reduce flicker. Using a deinterlacer can help clarity and stability of the image. Many deinterlacing algorithms are available in image processing literatures such as ELA and E-ELA. This paper propose a new statistical deinterlacing algorithm based on statistical tests such as the Bartlett test, the Levene test and the Kruskal-Wallis test. The results obtained from the proposed algorithms are found to be comparable to those from many well-known deinterlacers. However, the results in the proposed deinterlacers are found to be more efficient than other deinterlacers.
