Objective : The sacroiliac joint complex is often related with functionally incapacitating pain in old aged people. The purpose of this study is to delineate the investigation strategies and to determine the long-term effect of radiofrequency [RF] neurotomies for pain arising from sacroiliac Joint dysfunction[SIJD]. Methods : Sixteen patients were diagnosed as having chronic pain from SIJD by comparative controlled blocks on L5 dorsal rami, sacroiliac Joints and deep interosseous ligaments. After confirming the positive response [more than 50% of pain relief], sensory stimulation was applied to detect the 'pathological' branches. Subsequently, RF neurotomies were performed on the selected nerve branches. Surgical outcome was graded as successful, moderate improvement, and failure after a 6month follow-up period. Results : Stimulation intensity was 0.45V to elicit pain response in the L5 dorsal rami and lateral sacral branches. The number of RF-lesioned nerve branches was 6per patient. The average number of lesions for each branch was 1.3. Most commonly selected branches were L5 dorsal ramus [88%] and S2-upper division [88%]. Ten patients [63%] reported a successful outcome according to the outcome criteria after 6months of follow-up, and five patients [31%] reported complete relief [100%]. Five patients [31%] showed moderate improvements. One patient reported failure. Conclusion : RF neurotomy of lateral sacral branches is an excellent treatment modality for the pain due to SIJD, provided that comparative controlled block shows a positive response.

The purpose of this study is to establish landscape planning, and to find out to administrative system and improvement way on landscape plan in Korea. We have sought for research trend and the concept of landscape planning related to the landscape planning through the investigation of books and documents, and have analyzed the characteristics on the law for landscape plan in United State of America, United Kingdom,, France, Germany, Japan and Korea. As the results of this study are as follows; 1) A state developing local self-governing body as United State of America, United Kingdom and Germany carried out individually landscape plan. Especially, it raises clarity of administration to fix residents participation(Nonprofit Organization : NPO) and secures responsibility. 2) A state of centralized authoritarian rule as France and Japan applies common law to the nationwide but commission's concrete management or conference. 3) And so in Korea and applicable landscape plan was made on the basis of town-planning law and managed with ordinances for landscape. In here the important thing is division of role of central and local government and residents. This study proposes the system of planning and analyzed the related laws for the landscape formation and management. The future research on the character of the local areas, providing many chances with people in the community through publicity activities, and rearing the expert group on this matter should be made in the future.

This study is a comparative analysis of the creation and development of visual techniques used in girls' comics in the paradigmatic low and high-context cultures of American and Japan. As previous analyses have shown, there are qualitative differences in the expressive mechanisms employed in girls' comics in Eastern and Western cultures, and it is an investigation of this realm of expression that is the basis of this study. Particular emphasis is placed on an analysis of the structure of frames, one of the most fundamental expressive mechanisms in girls' comics. A close examination of this underlying structural component reveals that both cultures demonstrate autonomous growth, providing a theoretical framework for future studies.

Information sources about Mongolian pigtail of 13-14C are relatively rich. But it was difficult to estimate the shape of the pigtail in detail with the descriptions in historical writing or travel books only, and paintings were neither enough to observe the beautiful shape of the pigtail closely on the whole because the portrayed characters were always wearing their hats. However, the authors could trace the detailed shape of the pigtail of 13-14C through close investigation into Mongolian stone statue of the period. In conclusion, the authors performed a comparative study by historically comparing the historical writings, archeological materials, ethnological materials and figurative arts featuring medieval Mongolian pigtail. And the authors paid careful attention to the meaning of those materials to the hairdo history. Historically nothern minority races have become assimilated with surrounding races in language, culture and customs through long economical and cultural exchange, and today their national traits gradually fade away by globalization. But each minority race still stands independently and maintain its own traditional culture. only recently began the study by Korean researchers on Mongolian pigtail, and there is still much to be discussed in ethnological issues such as racial pedigree.

Detailed human gross anatomic structures have been characterized. No similar data are available in nonhuman primate species in spite of close phylogenic similarity found between man and nonhuman primates. The ever increasing incidence of lung cancer and air pollution related respiratory ailments found in man emphasizes the need for an ideal animal model for studying pathogenesis of these various human pulmonary diseases. Thus, detailed investigation of pulmonary structures found in various species of nonhuman primates is warranted. For determining primate gross pulmonary anatomic structure, published works concerning the number of tracheal cartilage, angle of tracheal bifurcation, caliber of trachea, lung lobe and bifurcation position of trachea recorded for several species of nonhuman pimates, were reviewed. Limited information is available concerning the number of tracheal cartilage, width of tracheal cartilage, angle of bronchus, caliber of trachea and bronchus, and the bifurcation position of the trachea including the length of bronchus on nonhuman primates. Since scanty data have been gathered with no specific reference to their age, sex and body weight, they have no comparative values.
