Background & Methods : In order to measure the acute and subacute toxicity of Vermilionum and it's anti-cancer effects, Sarcoma-180 abdominal cancer cells were injected intravenously. The following results were obtained after measuring the survival rate, toxicity of the NK cells, and IL- 2 productivity. Results : 1. It was impossible to measure $LD_{50}$ value in the acute toxicity test and no toxic effects were witnessed in the clinical observation. 2. No significant differences were shown in the weight changes between the experiment groups and the control group in the acute toxicity test. 3. No peculiar toxic effects were shown in the subacute toxicity test and the weight changes were insignificant between the experiment groups and the control group. 4. In measuring the survival rate after inducing abdominal cancer by Sarcoma-180, the experiment groups showed increased of 9.52% compared to the control group. 5. In measuring the activity of NK cells, no significant changes were shown between the experiment groups and the control group. 6. In measuring the productivity of IL-2, significant reduction was shown in the experiment groups compared to the normal group, but no significance was witnessed compared to the control group.

The Treaty of Friendship, Commerce and Navigation between the Chosun dynasty and Japan and the United States of America etc. began signing procedures from Feb. 1876. Thus, Busan port became an open port to foreign vessels in 1876. This has resulted in Busan port becoming the greatest port in Korea. This study explored records which were made by the Chosun dynasty and Japan on the opening and development of Busan port. The results are as follows ; According to making treaties between the Chosun dynasty and foreign countries, Chosun dynasty gradually opened a door to the international community. Various institutions were established in and around Busan port by Chosun and Japan. For example, maritime customs, a court of justice, police station by the Chosun side, a Japanese consulate, the Board of Trade for Japan etc by the Japan side. Records made by or related to these institutions and on the development of the Busan port during the open-port period and the Japanese colonial period were preserved at the Kyujanggak Institute for Korean Studies, the National Institute of Korean History, and the Busan Metropolitan Simin Municipal Library.

James Cameron's "Avatar" has broken the national record of movie ticket sales, and it caused the boom of 3D and 3D related fields. This research is focused on the appropriate ways to embrace the stereoscopic 3D cinema and the assumable result in Korea. The new stereoscopic 3D is different from the old fashioned analogue 3D, and it has many possibilities that may influence Korean film industry. Since 1990s, the number of Korean film school has increased drastically, and many of those who graduated from the schools would experience fierce job market. 3D converting projects that require a lot of film majored personnels would solve the overly supplied film majored professionals. Through Korea's hundreds of film schools, when they include 3D filmmaking in their curriculum, they can train and educate 3D related staff such as stereographer, convergence puller, and depth continuity artists, and Korea can be an important 3D staff train center in the world. Educating 3D filmmaking can produce a noticeable result in terms of accepting 3D cinema. Stereoscopic 3D cinema has many possibilities in many fields not only in cinema but also almost every fields that related to the imagery. With government's supports, the investments from the 3D related corporations, and 3D education in colleges would be fast and efficient way to embrace and accept stereoscopic 3D cinema in Korea in terms of the size and the profit.

In this paper, we have reported two interesting flow effects arising in the TRFGE sequence using water flow phantom. First, we have shown that the TRFGE sequence is indeed not affected by "in-flow" effect from the unsaturated spins flowing into the imaging slice. Second, the enhancement of "in-plane flow" signal in the readout gradient direction was observed when the TRFGE sequence was used without flow compensation. These two results have many interesting applications in MR imaging other than fMRI. Results obtained were also compared with the results obtained by the conventional gradient echo(CGE) imaging. Experiments were performed at 4.7T MRI/S animal system (Biospec, BRUKER, Switzerland). A cylindrical phantom was made using acryl and a vinyl tube was inserted at the center(Fig. 1). The whole cylinder was filled with water doped with $MnCl_2$ and the center tube was filled with saline which flows in parallel to the main magnetic field along the tube. Tailored RF pulse was designed to have quadratic ($z^2$) phase distribution in slice direction(z). Imaging parameters were TR/TE = 55~85/10msec, flip angle = $30^{\circ}$, slice thickness = 2mm, matrix size = 256${\times}$256, and FOV= 10cm. In-flow effect : Axial images were obtained with and without flow using the CGE and TRFGE sequences, respectively. The flow direction was perpendicular to the image slice. In-plane flow : Sagittal images were obtained with and without flow using the TRGE sequence. The readout gradient was applied in parallel to the flow direction. We have observed that the "in-flow" effect did not affect the TRFGE image, while "in-plane flow" running along the readout gradient direction enhanced the signal in the TRFGE sequence when flow compensation gradient scheme was not used.

Manganese is an essential element in the body. It is mainly deposited in the liver and to a lesser degree in the basal ganglia of the brain and eliminated through the bile duct. Rapid turnover of managanese in the body makes it difficult to evaluate the manganese exposure in workers, esecially in those with irregular or intermittent exposure, like welders. Therefore, conventional biomarkers, including blood and urine manganese can provide only a limited information about the long-tern or cumulative exposure to manganese. Introduction of magnetic resonance imaging (MRI) made a progress in the assessment of manganese exposure in the medical conditions related to manganese accumulation, e. g. hepatic failure and long-term total parenteral nutrition. Manganese shortens spin-lattice(T1) relaxation time on MRI due to its paramagnetic property, resulting in high signal intensity (HSI) on T1-weighted image(T1W1) of MRI. Manganese deposition in the brain, therefore, can be visualizedas an HSI in the globus pallidus, the substantia nigra, the putamen and the pituitary. clinical and epidemiologic studies regarding the MRI findings in the cases of occupational and non-occupational manganese exposure were reviewed. relationships between HSI on T1W1 of MRI and age, gender, occupational manganese exposure, and neurological dysfunction were analysed. Relationships betwen biological exposure indices and HSI on MRE werealso reviewed. Literatures were reviewed to establish the relationships between HSI, Manganese deposition in the brain, pathologic findings, and neurological dysfunction. HSI on T1W1 of MRI reflects regional manganese deposition in the brain. This relationship enables an estimation of regional manganese deposition in the brain by analysing MR signal intensity. Manganese deposition in the brain can induce a neuronal loss in the basal ganglia but functional abnormality is supposed to be related to the cumulative exposure of manganese in the brain, use of brain MRI for the assessment of exposure in a group of workers seems to be hardly rationalized, while ti can be a useful adjunct for the evaluation of manganese exposure int he cases with suspected manganese-related health problems.
