The purpose of this study is to elucidate the traits of the spatial orientation of urban residents. The analysis materials are the 110 rough maps which have been collected for the last ten years in Yeonsugu, Incheon metropolitan. The urbanites' spatial orientation are analysed from an aspect of the orientation elements and the orientation frames respectively. As a result, the urban dwellers make use of five elements - path, node, district, landmark, and language clue for their spatial orientation. Again the orientation frames of the urban people are investigated in terms of locating and directing in space. In regard to the former, they tend relatively to depend on horizontal axes based on broad streets and to prefer to position at the center on coordinate system. With reference to the latter, they show to be north-at-the-top directed tendency and to hold higher proportion of exocentric perspective than egocentric. Consequently urban residents tend to form spatial orientation with using five spatial elements, leaning horizontal axis, positioning themselves at the central part of coordinates, directing toward north-at-the-top through exocentric perspective.

Serum CA 125 is the most useful marker for monitoring patients with epithelial ovarian cancer. However, it can be elevated above normal level in a variety of conditions other than ovarian cancer such as endometriosis, pelvic inflammation disease, and other malignant or nonmalignant disorders, including pulmonary diseases. Recently, we experienced a case of bronchiectasis in which the serum CA 125 level was elevated, changing with the patient's condition. There was no evidence of underlying malignant disease on positron emission tomography or on gynecologic examination, including transvaginal ultrasonography. During follow-up for 14 months, we could not find any clue of malignant disease that could have been the cause of the elevated levels of serum CA 125. Elevated serum CA 125 level should be interpreted carefully according to the patient's clinical condition. In addition, our case suggests that CA 125 may be used as a surrogate marker for acute inflammatory status for chronic pulmonary diseases.

Familial hypokalemic periodic paralysis (HOKPP) is an autosomal dominant muscle disorder characterized by episodic attacks of muscle weakness with concomitant hypokalemia. Mutations in either a calcium channel gene (CACNA1S) or a sodium channel gene (SCN4A) have been shown to be responsible for this disease. The combination of sarcolemmal depolarization and hypokalemia has been attributed to abnormalities of the potassium conductance governing the resting membrane potential. To understand the pathophysiology of this disorder, we examined both mRNA and protein levels of delayed rectifier potassium channel genes, KCNQ3 and KCNQ5, in skeletal muscle fibers biopsied from patients with HOKOur results showed an increase in the cytoplasmic level of KCNQ3 protein in patients' cells exposed to 50 mM external concentration of potassium. However, mRNA levels of both channel genes did not show significant change in the same condition. Our results suggest that long term exposure of skeletal muscle cells in HOKPP patients to high extracellular potassium alters the KCNQ3 localization, which could possibly hinder the normal function of this channel protein. These findings may provide an important clue to understanding the molecular mechanism of familial hypokalemic periodic paralysis.

The movie WALL-E shows the Earth which has been overrun with garbage and devoid of plant and animal life, and humans who try to restore the ecosystem. The aim of this study is to find the implications of children's education with a detailed analysis of the movie's theme. The analysis method is the interpretive analysis model that is one of the qualitative methods of data analysis based on the concept of Wolcott. First, the Earth is an abandoned planet covered in trash: the Axiom is a haven for morbidly obese and indolent people. The main area of the earth's destruction, and the captain's cabin is the place to find a clue to awakening and change. Second, with the lapse of time, the Axiom becomes a ship allowing their return to earth. The Earth, recognized as their homeland, turns in to the land of hope when people return. Third, the cleaning robot Wall-E, as a main agent of change, has changed humans as well as itself. The results showed that we found nature-friendly development, destruction of nature, the criticism of modern civilization, the sanctity of life, ecological consciousness, coexistence, symbiosis and a win-win principle in our research.

This article reviewed ‘Gojangsijoseonju(고장시조선주)' which was written by Gojeong-ok(.고정옥), a scholar of Korean literature. and showed the features and importance in the history of Korean literature. Gojeong-ok was not properly studied in the history of Korean literature for the time being because he went to North Korea during the Korean war. Even for the researcher on Korean literature.' the literary works of Gojeong-ok were not introduced properly. However, the systematic studies on Gojeong-ok and his literary works should be done, and should be well appreciate his work in the history of the research for Korean literature by his achievements. This article considered his literary achievement through his book, 'Gojangsijoseonju'. 'Jangsijo(장시조), that was named by Gojeong-ok for 'Saseolsijo(사설시조), stood in highly important position to explain the history of literarature in late period of Chosun(조선) Dynasty. He tried the analysis on the fifty (50) selected 'Saseolsijo' and made commentaries on them in his book. And he suggested the original and creative theory on 'Saseolsijo' at the time of the book published. This article considered his understandings on the poems of classical literature, revealed in his literary works, and especially, the features on the theory for the 'Jangsijo'. Through this process, it could be clearly understand his views on literary works in itself. By considering the analysis of literature that was introduced with the commentaries, it could be seen the aspects of the specific analysis on each literature. Through these works, it could be looked forward to getting more detailed investigating clue on the view of Gojeong-ok for the poems of classical literature.

The compiled recent precise age data for the plutonic intrusions of Korean peninsula display that the Jurassic igneous activities occurred on the Yeongnam massif since ca. 200 Ma close to the boundary between Triassic and Jurassic. Since then the igneous activities propagated toward further north through time. The Jurassic igneous activities over the Okcheon belt and its vicinity areas began at about 180 Ma when igneous activities of the Yeongnam massif had been almost over. The igneous activities within the Gyeonggi massif located further north started at somewhat later period ca. 170 Ma. Jurassic igneous activities over the Okcheon belt and its vicinity areas ended a little earlier than the Gyeonggi massif area. Such timing differences upon geographic positions within the Korean peninsula seem to reflect variations in distance to the trench, in the direction of subduction, and/or in subduction angle. Therefore precise understanding of the variations in emplacement ages of Jurassic plutons within Korean peninsula can be a important clue to reconstruct the paleogeography and tectonic environment of the northeast Asia during the Jurassic.

The first key point to the successful pollination and fertilization in plants is the pollen pistil interaction, referring to the cellular and molecular levels, which mainly play active roles in limiting gene flow among maize populations and between maize and teosinte. This study was carried out to identify proteins and investigate the mechanism of gametophytic factors using protein analysis. W22 (ga1); which didn't carry a gametophytic factor and W22 (Ga1), a near iso-genic line were used for the proteome investigation. SDS-PAGE was executed to investigate proteins in the pollen and pistil of W22 (ga1) and W22 (Ga1). A total of 44 differentially expressed proteins were identified in the pollen and pistil on SDS-PAGE using LTQ-FTICR MS. Among the 44 proteins, a total of 24 proteins were identified in the pollen of W22 (ga1) and W22 (Ga1) whereas 20 differentially expressed proteins were identified from the pistil of W22 (Ga) and W22 (Ga1). However, in pollen, 2 proteins were identified only in the W22 (ga1) and 12 proteins only in the W22 (Ga1) whereas 10 proteins were confirmed from the both of W22 (ga1) and W22 (Ga1). In contrary, 10 proteins were appeared only in the pistil of W22 (ga1) and 7 proteins from W22 (Ga1) while 3 proteins confirmed in the both of W22 (ga1) and W22 (Ga1). Moreover, the identified proteins were generally involved in hydrolase activity, nucleic acid binding and nucleotide binding. These results help to reveal the mechanism of gametophytic factors and provide a valuable clue for the pollen and pistil research in maize. In addition, it might provide a comprehensive insight on the proteins that were involved in the regulation of pollen-pistil interaction.

The purpose of this study is to examine the feasibility of using stable isotopes as a hydrologic tracer, and to elucidate the groundwater circulation system and the source of S component dissolved in thermal water of the Chonju Jukrim thermal spring district based on the O, H and S isotopic variabilities of environmental materials including bedrock, rainwater, surface water, shallow subsurface water and thermal spring water. The ${\delta}^{18}O$ and ${\delta}D$ of subsurface waters and surface water show highly restricted range and plotted on the same meteoric water line as a ${\delta}D=8{\delta}^{18}O+19$ line, and derivate from the mean annual isotopic composition of the rain water but are analogous to those of rain waters precipitated during winter season, indicating that ground waters are originated from the meteoric water and are strongly affected by the seasonal variation of air mass. Thermal spring waters are more depleted in ${\delta}^{18}O$ and ${\delta}D$ than those of shallow ground water and surface water. It can be explained by the difference of recharge area. The hydrochemical properties of subsurface waters and surface water devide into two groups: $Ca(HCO_3)_2$ type including shallow subsurface water and surface water, and $Na(HCO_3)$ type of thermal spring waters. The ${\delta}^{34}S$ values of thermal spring water show very high positive and quitely distinct from those of shallow subsurface water and surface water that are similar to those of bed rocks, indicating that sulfate dissolved in thermal spring water has not only a terrigenic origin, but also originates partially from the foreign source containing very heavy ${\delta}^{34}S$ component such as an ancient sea water. However, the presence of $H_2S$ can not be ignore the affact of the isotopic fractionation to explaine the heavy ${\delta}^{34}S$ of thermal spring water. Overall, the Oxygen and Hydrogen stable isotopes can identify the source and the circulation system of the natural waters and the S-isotopes can provide a crucial clue on tracing the dissolved material transports in the circulation system of the natural water.
