Flora and standing crops of the periphyton communities were examined at five sites in the mountainous streams of the Dam of Peace, Korea, from June to November 2003. The attached algal communities comprised totally 76 taxa belong to the 5 classes. In species composition, diatoms and green algae overwhelmingly dominated the periphyton communities although their standing crops were low. During the survey period, major dominant species were Navicula gregaria and Nav. pupla var. capitata, as 11.7% and 8.9% of total standing crop, respectively. Other subdominant species were Scenedesmus ecornis and Spirogyra weberii in green algae, Cymbella affinis, Cymbella minuta. Fragilaria capucina, Melosira varians, Naw. cryptocephala, Nav. exigua var. capitata, Nav. gregaria, Nit. sublineuris in diatom. In the seasonal appearances, S. ecornis and Oscillatoria nigra were occurred in summer, C. affinis and F. capucina in autumn, and N. sublinearis, and species Spirogyra weberii in winter, respectively.

52 cases of metastatic lung tumor, including 22 [42.3%] choriocarcinoma., 13[25%] liver cancer, 6 [7.5%] stomach cancer, 2 bone tumor, etc, were reviewed at Busan National University Hospital, during a 5 year period ending with 1974. The age distribution of metastatic lung tumor were same in second decade to 5th decade. The most common appearances of roentgenograms of metastatic lung tumor were that of multinodular [42.3%], diffuse acinar [21.1%],infiltrative or pneumonic[21.1%], solitary lesion [9.6%] and diffuse micronodular [5.7%]. The metastatic lesions originated from choriocarcinoma revealed multinodular and acinar in roentgenogram, and the lesions originated from liver and stomach cancer revealed infiltrative and acinar. In our series, the positive hilar lymph node enlargement was encountered in 12 cases, of which 4 were in liver cancer and 3 were in stomach cancer. Pleural effusion was also encountered in 5 cases, of which 3 were in liver cancer. The treatment of this series was almost conservative except of 2 cases of pulmonary resection, and the reason of this limited cases of surgical treatment was seemed due to the delayed direction of metastasis to lung beyond the proper indication of surgery.

This study was conducted to investigate the ambivalent characteristics of dichotomous contradictions expressed by Robert Venturi's architecture. It focused on his Mother's House, which applied his theoretical practices faithfully among many of his architectural works. First, he sought to change interior and exterior spaces by manipulating the architectural scales of "Mother's House". He achieved tension in space through structural complexities in combination with contradictions. Second, as for the characteristics of ambivalent contradictions, including linear and geometric forms, and plane, there were familarity which emphasizes tradition; external appearances of symmetry and asymmetry which give a comfort feeling; openness and closedness, which were expressed with the size of windows and objects such as molding. Third, the fireplace-chimney and the stair were forming appropriate harmony between contradiction and complexity as they competed for central position on the plane.

Under the social conditions that an understanding of a men change socially and men's interests in their appearances are on the increase, this research intends to study and analyze the changes of people's sensibility of values on ads for men's cosmetics, which is said to be performed the social, cultural function reflecting the social consciousness, the value and the idea creating a new one. The documents for the research was sindonga. The documents were analyzed quantitatively in regard of contents of a linguistic expression and a visual expression showing on advertisements for man's cosmetics, a time series analysis. As a result of analyzing the consumption value through headline of an ad, the emotional value took the highest percentage extending whole periods. Beside emotional value, a time series analysis showed that social values appeared to the major themes in the 1970s, and functional values was important themes in 1980s, and the social values and functional values appeared equally during 1990-2002.

In brain MR imaging, contrast-enhanced study is important in the detection and characterization of lesions. As a postcontrast brain MR imaging, conventional T1 weighted imaging has been usually used. Magnetization transfer imaging has been used to increase conspicuity of enhancing lesions. In addition, fat-suppression imaging can be used as in other parts of the body. Recently, FLAIR sequence has been reported to be useful in detecting subarachnoid, meningeal, and subdural abnormalities. In this exhibit, we demonstrate basic principles and typical appearances of various pulse sequences that can be used as a postcontrast brain MR imaging in children. Furthermore, we discuss imaging strategies to increase clinical usefulness of postcontrast brain MR imaging for specific abnormalities. The advantages and disadvantages of each pulse sequence are also discussed.

Although mammography is the primary imaging modality for the breast, it has its limitations especially with dense breast parenchyma. Breast magnetic resonance imaging (MRI) has evolved into an important adjunctive tool as it is currently the most sensitive technique for breast cancer detection. Despite this high sensitivity, overlap in the appearances of some benign and malignant breast lesions results in additional unnecessary intervention with negative results. These false positives, in addition to high cost and limited availability, necessitate establishing proper indications for breast MRI. The literature was here reviewed for recent clinical trials, meta-analyses and review papers which have studied this important subject. PubMed; the US national library of medicine, was utilized to review the literature in the last twenty years. Using the obtained information, current uses of breast MRI are discussed in this paper to determine the indications which are relevant to clinical practice.

The concept of Blood Stasis had been cognized merely as a sign in disorder of blood circulation since "Huangjenaegyeong(黃帝內經)" until "Sanhanron(傷寒論)" and "Geumgweyoryak(金匱要略)" started to describe, explain and apply independent symptom of blood stasis to practice. In this article, establishing the estimate feature of symptom of blood stasis in "Geumgweyoryak(金匱要略)" is the main subject, in sequence the pathological mechanism and targets of prescriptions suggested in "Geumgweyoryak(金匱要略)" are analyzed and restructured. In conclusion, the symptom of blood stasis in "Geumgweyoryak(金匱要略)" is caused not only from disorder of blood circulation but also from metal depression, therefore there are always appearances of excessive and deficient status simultaneously, in the process of symptom. The research on concept of blood stasis from the literatures in early ages will be the basis of future studies about disease of circulation in Korean Traditional Medicine.

The odontogenic myxoma is an benign, slow growing neoplasm which is of ectomesenchymal origin. This neoplasm occurs almost exclusively in the jaw bones and comprises 0.2% to 17.7% of odontogenic tumors. The odontogenic myxoma may show a wide spectrum of radiographic appearances, unilocular, multilocular radiolucency and a distinct or diffuse border, making the differential diagnosis difficult. We present a case of the odontogenic myxoma in the maxilla with conventional and recent image modalities. Occlusal film revealed a medially extended multilocular lesion with intralesional fine and straight trabeculations from the scalloped margin and buccal expansion and thinning of cortical bone. Computed tomogram revealed lesion showed equivalent density to the muscles in the left maxillary sinus with partial cortical discontinuity of medial wall and the tennis-racket pattern with internal straight trabeculations. MRI revealed intermediate signal intensity on Tl weighted image and high signal intensity on T2 weighted image. In Gd enhanced MR image, the peripheral portions of the lesion were enhanced.

The study is to find out any significant relations in clothing behaviors according to attitudinal body image and plastic surgery attitude. The sampling method was a convenient sampling, and the subjects were 190 male and 160 female students in Daejeon. The survey was conducted from June 20 to July 15, 2008. The data were analyzed by the frequency analysis, Cronbach' ${\alpha}$, factor analysis, t-test and variance analysis. The subjects who pay much attention to weights and appearances have a positive attitude to plastic surgery. As they concern their body weights and appearance, they have high exhibition of clothing. Those who think their body as being attractive have been more interested in clothing and fashion. The subjects who have positive attitude for plastic surgery are more interested in clothing and fashion, showing higher conformity of clothing.
