Gastritis cystica profunda (GCP) is a rare disease characterized by gastric foveolae elongation along with hyperplasia and cystic dilatation of the gastric glands extending into the tissue beneath the submucosa. GCP mainly develops at the gastroenterostomy stoma but can arise in a stomach that has not undergone surgery. The proposed pathogenesis is related to chronic inflammation, ischemia and the presence of a foreign body. GCP may present as a submucosal tumor, Polyp or a giant gastric mucosal fold. Endoscopic ultrasonography (EUS) is an effective diagnostic method for differentiating GCP from protruding and elevated gastric lesions. We report a case of GCP along with the endoscopic and EUS findings that were indistinguishable from a malignant submucosal tumor.

近代化가 섬의 文化生態界에 미친 影響 : 鬱陵島

朴贊石 慶北大學校 社會科學大學 地理學科 1987 地理學論究 Vol.- No.8

This research has attempted to pursue how residents of the island perceive their resources in the processes of modernization and how they adapt cultural landscape of the island. The development of the island is entirely relied on the exogenous variables from the mainland. It is mainly due to its distance, size of space, isolation and resident's perception. This island has never experienced having a generating power being responsible for development by themselves. They perceive the cultural wave is high as much as the wave of the East Sea. Resident's perception has shifted on resources of the island from lumber, squid, to tourism by the interactions with the mainland. Cultural landscape is moving fast toward metropolitan culture of Korea. Does the tourism be ever lasting resource of the island? Rooted residents moved out of the hometown looking for better opportunities and new migrants also want to leave for mainland as soon as their economic success. In this manner of modernization desirable for the national development and its integration? Government should be invested in infrastructures of the island to hold residents where they live. Simultaneously residents organize their society to do something more than aliens and integrate agriculture, fishing, and tourism, and diversify their supportive service sectors in order to sustain healthy culture and socio-economic structure of the island.

In the sensory test, the 7% added group had the strongest color according to the texture; the highest cohesiveness was shown in the 5% added group. and the highest springiness was shown by the 3% added group, but none of these showed any significant differences. As for flavor, the more JP added the higher the stale grain flavor and bitterness. In the result of the overall acceptability test, the stale grain flavor of the 5% added group showed the highest values for the favorite texture and flavor. From the results of this experiment, when making stale grain flavored Jeung-Pyun, the 3 and 5% added groups were the optimum concentrations for the observed improvements in the quality. This study was carried out to investigate the possibility of improving the quality characteristics of Jeung-Pyun, by the addition of Paecilomyces japonica powder (JP). Regarding the volume of the Jeung-Pyun fermentation, with respect to the different amounts of JP added, the groups containing JP showed increased volumes, and as for the pH, the group containing 5% showed the lowest value. Regarding the moisture content, the groups containing JP showed lower moisture contents than the control group. Regarding the amino acid content, the control group showed a higher amino acid content than those of the JP containing groups, and contained an even amount of essential amino acids, and Leucine, Phenylalanine and Arginine were especially

A wearable electrodiagram(ECG) monitoring system is a widely used non-invasive diagnostic tool for ambulatory patients who may be at risk from latent life-threatening cardiac abnormalities. In this paper. we have a portable ECG monitoring system with conductive fiber characterized by the small-size and the low power consumption. The system consists of conductive fibers, one-chip microcontroller, ECG preprocessing circuit, and monitoring software to record and analyze in PC. ECG preprocessing circuit is made of pre-amplifier with gain of 10, band-pass filter with bandwidth of 0.5-120% and 2.5V offset circuit for A/D conversion. ECG signals obtained by sensor are corrupted by noises such as a baseline wandering, 60Hz power noise and interference noise by body movement. For cancellation of noises in signals obtained by conductive fiber, we used the wavelet decomposition of wavelet transforms in MATLAB toolbox.

War and peace is the permanent problems of politcal science. The order of international relation today has been divided into friendship or hostilities. Political ideologies have displayed an hostile action between democracy and communism, capitalism and socialism, which has agapavated the conflict. The prevent of international war and the preservation of peace is the most important issue of international politics. The world's armed force and total destructive power of weapons has increased to the present time and will be increased to the future. As a result, we are pessimistic about the world peace and doubt about the preservation of peace. But we must inquire into the effort for the peace which is the eternal task of the epoch.

地域開發의 理論的 接近 : Center-Periphery Model

朴贊石 慶北大學校 文理科大學 1974 文理學叢 Vol.2 No.-

The Regional development planning should be distinguished from the national development in terms of balance versus imbalance, welfare versus growth, and dispersion versus concentration. Most of developing countries mainly concentrated on growth rate of GNP, and therefore they have no time to pay attention the backward areas which they thought it the low investment return areas. But the cumulative investment on the center region brought the regional disparity between urban area and rural area, and moreover regional disparity, the defeciency of spatial organization has hampered the national economic growth. It is obvious that regional problem is national problem. The goal of regional development in the developing countries are; a) the gradual elimination of the periphery on a national scale by substituting for single, interdependent system of urban region, b) the progressive intergration of the space economy by the extention, on a national scale, of a system of efficient commodity and factor markets. The center-periphery model is colonial relationship; center is existed once on the space, it took comparative advantage over the periphery. One single center in the whole country has not distributed the domination to the rest of country. Center-Periphery Model could be found any space such as global, continental, national, and regional scale. In order to achieve spatial organization efficiently, full integration of the national space economy, opportunities for the further expansion of economic system, and efficiency in the location of new investment projects, growth pole policy in the backward region are available in regional development planning.
