The treatment, management and long-term retention of mandibular molar teeth exhibiting furcation invasions always have been a challenge to the discerning general dentist or dental specialist. This is especially true when the furcation involvements has progressed to a class Ⅲ furcation. This study presents and describe various therapeutic plans available for class Ⅲ furcation invasions in mandibular molars, discussing the advantages and disadvantages of each approach. This study focus particularly on a surgical technique called "tunneling'', which is performed to describe the remaining soft and hard tissues in the furcal area ; this, in turn, allows access for effective oral hygiene and maintenance. The objective of this study and subsequent case report is to discuss and illustrate the tunneling procedure as a treatment alternative for mandibular class Ⅲ furcation invasions.

Renal cell carcinoma can presents wide range of signs and symptoms, and commonly associated with paraneoplastic syndrome. Paraneoplastic manifestations are present in up to 20% of patients with renal cell carcinoma. There is convincing evidence that renal cell carcinoma tumor cells elaborate proteins that serve as mediators of endocrine (ex ; ectopic production of parathyroid hormone-related protein or erythropoietin) as well as nonendocrine paraneoplastic syndromes. A paraneoplastic syndrome may be the various clinical presentation of renal cell carcinoma in a significant number of patients, therefore mimicked other general disease. We report a case of renal cell carcinoma associated with paraneoplastic syndrome mimicking pyelonephritis.

I went deep into the study of gymnastic form and quality in Shilla period focus on Whalang on this dissertation. Especially with Whalang institute, various elements, which are physical sufferings in a coming of age ceremony, life and reincarnation in 'Mudu,' plays in religious celebration, physical ability for Dule, take part in the origin and formation of Whalang. 1. These physical elements were originated from the traditional life style of Korean race. The concerted qualities, which were join sports, moral training in association, strong partnership as a military group, contributed meanings to the formation of Whalang gymnastics. 2. The basic idea of Whalang was 'shining' which meant 'Gwangmyung' (a bright flash of hope). Whalang embodied the Gwangmyung idea and its ideal human was supposed to be aboveboard and cheerful. The construction of Whalang became systematical at about 6th century. It consisted of Whalang from noble birth and unmarried Nangdo from a respectable family. Whaju working at the government was in charge of Whalang institute. 3. The Whalang education divided into 3 parts. The first one was moral education for a member of a nation such as loyalty, patriotism and faithfulness. In those days, the 3 parts were not totally separated, rather related to each other. Most of all, gymnastic was one of the significant elements because Whalang education was based on actions. Whalang pursed the investigation of a physical beauty beyond physical excellence for utility, which was Korean traditional idea about human body. 4. The Whalang idea about human body was cultivation of physical morality founded on the thoughts about body called 'Sim Sin Bul Bun Li Lon,' which means body and soul cannot be apart from each other. What Whalang wanted to be was a perfect human with harmony of body and soul based on the thoughts of 'Sim Sin Bul Bun Li Lon,' and what they wanted to achieve was realization of Gwangmyung idea in the human life. Those were gained by physical training and exercises. 5. Whalang thought that body and soul could not ever be apart from each other. Therefore in Whalang training, there were physical sufferings, which was dong violence to body on purpose and putting up with it, discipline of 'Donggi,' and retiring to a mountain to enter the priesthood alone. These came from the strong desire to gain physical morality as well as to study physical beauty.

Colors reprodued by color image processing system are affected by various physical factors and environmental conditions. Therefore it is difficult to reproduce the original object color accurately. Thus color calibrations of the input and output data of color image processing system based on spectral distributions are required. We propose a color calibration algorithm by considering spectral characteristic of the chosen color reproduction system which can be applied to device independent color reproduction using characteristic vectors of surface reflectance. The method comprised of two steps. The first step is color analysis step which reproduces the original object color from the camera output using color characteristic vectors. The second step is color synthesis step which displays the original color accurately on the monitor by considering the monitor's phosphor spectra. The spectral responsivities of camera sensors and phosphor spectral characteristics of a given monitor are evaluated. Also, to evaluate color reproducing characteristic we applied the proposed color calibration algorithm by choosing Macbeth ColorChecker's twenty four color spectra as a test color set. As a result, we reconstruct the actual color very closely on monitor using the proposed color calibration algorithm.
