An 11-year-old female toco toucan (Ramphastos toco) kept in outdoor exhibit was presented with sudden onset of anorexia and hypodynamia. After routine physical examination, the patient was treated. However, the bird died that evening. Necropsy revealed moderate swelling of the liver with yellowish discoloration. Based on the gross pathology as well as histologic evidence of iron pigments accumulation throughout the hepatocytes, hepatic hemochromatosis was diagnosed.

This thesis is written under the hypothesis that there are three images of the thoroughfare Kiso in this novel. First, I illuminated historical roles of the thoroughfare Kiso and many lives of roadside inhabitant. In this process, I realized the road which is made for the political purpose, attends political task. I found that there are many stories of pain and grief of humble classes. according to performing a duty, they are described in detail and realistically. I came to a conclusion that this novel is classic historical fiction. Second, I illuminated aspect that the road is caught up battlefield. In this process, I found many inhabitants who wanders from place to place. They are scrambling to escape refuge. Paradoxically, in spite of battle, an enemy can become a friend. in this battle. Through the battle, thoroughfare Kiso is able to be an important role in Japanese history. I also came to a conclusion that this novel is logotional historic fiction. Third, I found that there is another road is not described directly in this novel. Readers can guess third road which is hidden images. I would like to name this images the road of mind. Through this hidden images, novelist Shimazaki Touson could describe his view of history, philosophy, his attitude toward life, and his political view. Conclusionally, this novel is not only a requiem of tragic hero Aoyama Hanzo but also novelist Shimazaki Touson′political belief.

This study was conducted to investigate the effects of physical character and frality by the level of grip strength (GS) in elderly men. The study included 503 men in their 70s and 80s with no heart disease or physical limitations. There were no significant differences in age, height, body weight, body mass index, blood pressure, or ability to walk in place for 2 minutes when the subjects were divided into low-GS and high-GS groups (p>.05). However, the high-GS group had significantly better performance in the Timed Up and Go test (p=.024), the 30-second chair-stand test (p=.003), and the Figure-8 walking test (p=.014). GS in older men can serve as a positive predictor of frailty. 본 연구는 고령 남성의 악력 수준이 신체적 특성과 노쇠에 미치는 영향을 알아보고자 하는데 목적이 있었다. 본 연구의 대상자들은 1,800명의 고령자 중 심장질환과 신체적 기능에 이상이 없는 70-80대 남성 503명을 대상으로 선정하였다. 상대악력에 따라 L-GS 집단과 H-GS 집단으로 구분한 결과, 연령, 신장, 체중, 신체질량지수, 혈압 그리고 2분 제자리 걷기에서는 차이가 나타나지 않았다(p>.05). 그러나 의자에 앉아 3m 앞 표적 돌아오기(p=.024), 의자에 앉았다가 일어서기(p=.003), 8자 보행(p=.014)은 유의한 차이가 나타났다. 그러므로 70대, 80대 고령 남성의 악력은 노쇠의 긍정적인 예측인자로 역할을 할 수 있다.

The main purpose of this study is to evaluate the quality characteristics and antioxidant properties of jelly prepared by adding 0%, 25%, 50%, 75%, 100% of fermented freeze-dry velvet extract (FVE), which is rich in bioactive substances and has high added-value competitiveness through the development of applied products. In addition, the pH and water content decreased significantly, but the sugar content increased (p<0.001) as the amount of FVE added increased. In the color test, the L value decreased as the amount of FVE added increased, but the a and b values significantly increased. The hardness was the lowest in the control group to which the FVE was not added, and showed a tendency to increase significantly as the content increased (p<0.001). The DPPH and ABTS antioxidant capacities of FVE were higher than those of common dry velvet extract (CVE) (p<0.05). Summarizing the above results, most of the groups added with 25%~50% of FVE obtained high evaluation scores, and it is considered that 50% was the most appropriate as the optimal concentration to maintain the overall quality.

The characteristics of copper thin films and pattern filling capability were investigated by ECD. Prior to deposition of copper film, seed-Cu/Ta(TaN)/$SIO_2$(BPSG)/Si structure was manufactured. Copper deposition was performed with various current waveforms(DC/PC, 1~10,000Hz) and current densities(10~60 mA/$\textrm{cm}^2$) after pretreatment (Oxident removal, wetting) of seed-layer. Conformal pattern filling was performed using PC method with fast deposition rate of 6,000~8,000$\AA$/min. Heat-treated($450^{\circ}C$, 30min) copper films showed good resistivities of 1.8~2.1$\mu$$\Omega$.cm. According to the XRD analysis, (111)-preferred orientation of copper film was found in ECD-Cu/seed-Cu/Ta/$Sio_2$/Si structure. Also, we have successfully achieved to fill via holes with 0.35$\mu\textrm{m}$ width and 4:1 aspect ratio.
