Purpose: The purposes of the study were 1) to examine what relationships exist between PTE(perceived treatments effect) and PPS(perceived physical suffering) as the independent variables and hope as the dependent variable and 2) to examine whether PTE and PPS predict hope in cancer patients in their post-operative period within the Stotland's hope theory. Method: The Visual Analog Scale was used for measuring PTE and PPS and the Kim & Lee's Hope Scale which had acceptable reliability and validity was used for measuring hope. The data was collected from 38 hospitalized cancer patients who were in the post-operative period with a convenient sampling method. Result: There was a significant positive relationship between hope and the PTE in the low PTE group. There was a significant negative relationship between hope and the PPS in the low PPS group. There were no significant relationships between hope and the PTE in the high PTE group, and between hope and the PPS in the high PPS group. And the PTE explained hope with 71.2% of the variance in the low PTE group. Conclusion: PTE in the low PTE group and PPS in the low PPS group were identified as the factors to explain hope.

This traditional government office buildings of Choson Dynasty which exist in our country can be divided into two types (central and local government office buildings). Among them, the local government office buildings of Choson Dynasty are compoded of Nae-a, Dong-hun, Gaeg-sa, Hyang-Chung and Yook-bang-guan-chung. This study focuses on the Dong-hun, the central part of the local government office building, and tried to discover the specific regional featues of its construction type and analyze these various peculiarities focused on 14 local government buildings which can be found in Chung Nam local province. The results of this study are followings : 1. The shape of Dong-hun plan : It has almost '一'letter shape plan symmetrized On-dol on each side of Daechung (a king of floor) and Tae-maru in front. 2. The type of bracket structure : The bracket structures of Dong-hun is almost Muchulmok-choikong (10) and the rest of those are types of Min-do-li house(4). Therefore most of those are the buildings of earlier Choson Dynasty. 3. The form of the frame : Most of the frames are composed of double girders and five cross beams. 4. The form of the king post : There are six trapezoid king posts, four Paryun king posts and no Dongjaju king post. And the rest three king posts are hard to identify because of the transform of inner space. 5. The form of the roof : Dong-hun has a combination of trapezoid and triangular shape roof and most of them have single eaves(10).

Here in this study, we isolated 1,2,3,4,6-penta-O-galloyl-β-D-glucose (PGG) from Curcuma longa L. and elucidated the lifespanextending effect of PGG using Caenorhabditis elegans model system. In the present study, PGG demonstrated potent lifespan extension of worms under normal culture condition. Then, we determined the protective effects of PGG on the stress conditions such as thermal and oxidative stress. In the case of heat stress, PGG-treated worms exhibited enhanced survival rate, compared to control worms. In addition, PGG-fed worms lived longer than control worms under oxidative stress induced by paraquat. To verify the possible mechanism of PGG-mediated increased lifespan and stress resistance of worms, we investigated whether PGG might alter superoxide dismutase (SOD) activities and intracellular ROS levels. Our results showed that PGG was able to elevate SOD activities of worms and reduce intracellular ROS accumulation in a dose-dependent manner.

Objectives: Primary malignant tumors in the salivary glands are relatively rare. Because of the rarity and the different histopathologic patterns, it is difficult to establish a uniform treatment strategy. The prime treatment of salivary gland malignancy is the surgery, but the role of radiotherapy has been under debate. Radiation therapy combined with conservative surgical procedures may be as successful and perhaps more rational treatment than radical surgery alone. The aim of this study is to evaluate clinical pattern, incidence, treatment modality and outcome of the salivary gland maligancy. Materials and Methods: The medical records of 32 patients with malignant neoplasm of salivary gland who treated at the Keimyung university Dongsan hospital were analyzed retrospectively. Results: The overall 5 year survival rate was 77.9% stage I : 100%, stage II : 75%, stage III : 66.7%, stage IV : 55.6%). The 5 year survival rate according to tumor grade was 100% in low grade malignancy, 71.8% in high grade malignancy. The 5 year survival rate according to treatment modalities was as follows: Surgery only group was 83.3%, combined treatment group with surgery and posoperative radiation was 74.6%. Conclusion: The factors affecting prognosis is variable, but the stage at the time of diagnosis, site of lesion, tumor grade, histologic subtype were important factors. Surgery was the prime treatment tool and postoperative radiotherapy was also imperative in higher stage patient, high grade tumor, or patients with positive surgical margin.
