This study was conducted to analyze the phenotypic trends and environmental factors affecting the following carcass traits : slaughter weight, backfat thickness and carcass grade, in 1,251,572 commercial pigs for 7 years from 1999 to 2005. The average slaughter weight of female, male and barrow were $82.97{\pm}0.008$ $82.00{\pm}0.090$ and $82.79{\pm}0.008$, respectively. The average backfat thickness of female, male and barrow were $19.27{\pm}0.006$, $15.99{\pm}0.072$ and $22.49{\pm}0.006mm$, respectively. The slaughter weight tended to increase over the slaughter years, for backfat thickness remained, even though a significant drop of backfat thickness on 2002($18.75{\pm}0.027$). The slaughter weight was significantly higher in winter($83.29{\pm}0.032$), while the backfat thickness was significantly lower in summer($19.10{\pm}0.026$). The carcass grade A increased from 2000 to 2003, but decreased slightly after 2003. On the contrary, the carcass grade B decreased from 2000 to 2003, but increased slightly after 2003.

Hemiplegic migraine (HM) is a rare subtype of migraine with aura and is accompanied by a fully reversible motor aura. HM can occur in two forms: familial or sporadic. Currently, three genes are related to familial HM. Typically, HM occurs in the first or second decade of life and involves gradually progressing aura symptoms in succession, accompanied by headaches. The aura includes visual, sensory, motor, aphasic and often basilar-type symptoms. Motor aura (weakness) is related to the regions where the sensory aura is involved, and it usually starts at the hand before spreading to the arm and face. Aphasia is a common form of speech aura, but does not typically present as a difficulty in understanding. In this case report, the sensory-motor aura started at the right face and then gradually progressed to the right leg without any symptoms in the ipsilateral upper extremity. To the best of my knowledge, there has been no previous case report for the presentation of a hemiplegic migraine, as in this case report. As there is a possibility of misdiagnosis of Bell's palsy at the early stage of this case, this case report suggests that a physician should consider the rare possibility of stroke or HM when a patient presents with unilateral facial palsy.

High spatial resolution satellite image classification has a limitation when only using the spectral information due to the complex spatial arrangement of features and spectral heterogeneity within each class. Therefore, the extraction of the spatial information is one of the most important steps in high resolution satellite image classification. This study proposes a new spatial feature extraction method, named SSI(Shape-Size Index). SSI uses a simple region-growing based image segmentation and allocates spatial property value in each segment. The extracted feature is integrated with spectral bands to improve overall classification accuracy. The classification is achieved by applying a SVM(Support Vector Machines) classifier. In order to evaluate the proposed feature extraction method, KOMPSAT-2 and QuickBird-2 data are used for experiments. It is demonstrated that proposed SSI algorithm leads to a notable increase in classification accuracy.

UV-visible absorption measurement techniques using several horizone viewing directions in addition to the traditional zenith-sky pointing have been recently developed in ground-based remote sensing of atmospheric constituents. The spatial distribution of various trace gases close to the instrument can be derived by combing several viewing directions. Multi-axis differential optical absorption spectroscopy (MAX-DOAS) technique, one of the remote sensing techniques for air quality measurements, uses the scattered sunlight as a light source and measures it at various elevation angles (corresponding to the viewing directions) by sequential scanning with a stepper motor. A MAX-DOAS system developed by GIST/ADEMRC has been applied to measuring trace gases in urban air and plumes of the volcano and fossil fuel power plant in January, May, and October 2004, respectively. MAX-DOAS spectra were analyzed to identify and quantify $SO_2,\;NO_2,\;BrO,\;and\;O_4$ (based on Slant Column Densities, SCD) in the urban air, volcanic plume, and fossil fuel power plant utilizing theirs specific structured absorption features in the UV-visible region. Vertical scan through the multiple elevation angles was performed at different directions perpendicular to the plume dispersion to retrieve cross-sectional distribution of $SO_2\;or\;NO_2$ in the plumes of the volcano and fossil fuel power plant. Based on the estimated cross sections of the plumes the mixing ratios were estimated to 580 $SO_2$ ppbv in the volcanic Plume, and 337 $NO_2\;and\;227\;SO_2$ ppbv in the plume of the fossil fuel power plant, respectively.

The International TOVS(TIROS Operational Vertical Sounders) Process Package(ITPP-VI), which has been installed at Korea Meteorological Administration(KMA), is only for a global usage to need a surface data to generate atmospheric soundings and total ozone amount. If the initial input process in the ITTP-VI is not modified, it takes climatic surface data for producing sounding data and total ozone amount in general. KMA is trying to improve the quality of TOVS total ozone amount using real-time synoptoc observation in various ways instead of climatological data because this retrieved data in the new scheme for total ozone presently used at the KMA may critically provide to analyze the long-term trend of ozone structure over the Korean peninsula. Two cases in this study show that TOVS retrieved total ozone amounts used by synoptic surface observations can delineate more detailed ozone structures rather than those used by climate surface data. The distribution of TOVS retrieved ozone amount fields with the synoptic surface analyzed data(TOVS-GPV) show more in detail relatively than those with the climate data(TOVS-CLIMAT) as expected. In addition, the collocated inter-comparisons of TOVS-GPV with TOVS-CLIMAT, TOMS observations and Dobsometer observations are performed statistically. TOVS-GPV fields with TOMS observations show smaller bias relatively than TOVS-CLIMAT and also reduce the differences.

SAR imagery usually reveals the influence of antenna look-direction on the delineation of geological structures. In this study, the look-direction bias in SAR image is quantitatively analyzed specifically for geological lineament study. Geologic lineaments are estimated using both Landsat TM and JERS-1 SAR images over the study area to quantitatively compare and analyze the look-direction bias in the SAR image. The standard geologic lineaments in the study area are established from lineaments estimated from TM images, field mapping, and fault lines in a published geologic map. The results show that lineaments normal to radar look-direction are extremely well enhanced while those parallel to look-direction are less visible as expected. However, certain lineaments even parallel to radar look-direction can still be detectable in a favorable topographic condition. Compared with TM image, the total number of detected lineaments in each direction in the SAR image increases or decreases ranging from 33% to 159% in length and from 28% to 187% in occurrence. The ratio of lineaments in SAR image to those in TM image with respect to direction can be fitted by a cosine function. The fitted function indicates that geological lineament is more easily detected in SAR image than in TM image within about $\pm$50$^{\circ}$ normal to radar look-direction. And lineaments with limited extension appear to be more sensitive to the look direction bias effect.

This paper pay attention to silent puppets which appear in the traditional puppet performance. Not only movement of silent puppets which are involved with expression of body of the mime, but also various methods overcome limits of the silent are studied in this paper. Through the study of performance method and historic unfolding aspects, I confirm two main points. First point is that overcome limits of the silent, through the diversity of performance aspects. Second point is that silent puppets have been existed since the early stage of history, and show typical unfolding aspects on their way. Combining two main points, We can say that silent puppets go through continuous unfolding aspects on their way and have meaning of existence. The meaning of existence are that silent puppets seek deviant desire which deviate from everyday life and transcendental desire which seek a freedom through an imagination or an idea. It is interesting that the reasons of existence are associated with the emphasis of necessity which is encouragement of audience's desire and imagination that are necessary of accomplish of mime. After all, silent puppets say that diverse attempts which overcome limits of the silent are accomplished with the performance aspects and historic unfolding aspects, and through that sought unusual communication. Through the performance methods and signification aspects, silent puppets say that diverse groping for which maximize of audience's imagination, stimulation of imagination for audience's spontaneousness, and diverse groping for audience mind performance have been performanced as well. I think that those are the voice of silent puppets for activity of mime in the korea.

This paper explains what Japanese progressive liberalism was in postwar Japan by clarifying Maruyama Masao's "Cold War Liberalism," focusing especially on his realism and nationalism searching for "democracy" and "peace" in the context of the early Cold War Japan. Maruyama's Cold War liberalism can be grasped from two perspectives: how the Cold War defined his liberalism and how Maruyama interpreted the Cold War as a liberalist in postwar Japan. The liberal interpretation of the Cold War captures the spatial manifestations of liberalism in the Cold War while Cold War liberalism was to grasp the temporal succession of modern Japan. Maruyama revealed his liberal thinking by combining it to his idea of nationalism and realism. He was concerned about the reshaping of the fascist atmosphere provoked by anti-communism emerging from 186 | 동북아역사논총 59호the Cold War confrontation structure. He sought "neutrality" and "peace" to overcome the so-called "two worlds" of the Cold War. And he stressed the importance of "fair judgment" and "autonomous association" to restrain the fascistic atmosphere in postwar Japan. For Maruyama, subjectivity aimed at the concept of "nation" rather than "citizen," and nationalism was a condition for "democracy" and "peace" in postwar Japan. Maruyama's critical liberalism worked through nationalism and realism.

This paper aims to shed light on the structure of "Eonji[言志]" to demonstrate that it is a song with educational purposes, which is evident in its meaning and constitution. Based on various records of the epilogue and from the texts handed down several generations, it is clear that is an educational song that describes the life of ascholar and the core of knowledge as considered by Lee-Huang. Therefore, the meaning contained in Eonji[言志] is closely related to Lee-Huang's thoughts and it reflects the Confucian way of life. In the 4thphase, Pimi-ilin[彼美一人] of Eonji[言志] states that self-learning and serving the king can be carried out concurrently. The 5th phase of Eonji[言志] describes the anxiety of the lord for the wiseman and urges people to live a life full of consideration. This shows that one should not disregard the fact that a wise man's scholarship and life can contribute to the politics of the real world, even if the wise one chooses to lead a life of seclusion; even when the wise man enters the word of politics, his behavior and traits must not deviate from the calm course of self-cultivation in nature. The structure of Eonji[言志] and its different phases comprising nature, scholarship, and education deal with the following matters: "the meaning of retirement into nature (1stphase)," "nature+the practice of scholarship (2ndphase)," "scholarship+the practice of education (3rdphase)," "nature+the stance of scholarship (4thphase)," "scholarship+the stance of education (5thphase)," and "the beauty of nature+idea of scholarship and education (6thphase)."

This thesis explores how JobGeuk ShimChungWangWhoJeon and the Devoted daughter ShimChungJeon scenario have transformed ShimChungJeon, a notable work of Pansori literature, dramatically for modern times. By analyzing the adapter's consciousness and changing direction in these two works, it was found that ShimChungJeon was tailored to audiences in the 1900s. JobGeuk and the scenario are attempts to transform ShimChungJeon to meet cultural needs in the 21st century and to make the works appealing to the public. The aspects of the transformation of JobGeuk ShimChungWangWhoJeon are 1) reinforcement of logical causality, 2) weakening the humor and simultaneously emphasizing the work's surreal nature, and 3) dramatic expression by song. The aspects of the change in direction of the Devoted daughter ShimChungJeon scenario are 1)the insertion of a new narrative, 2)trying to evoke both humor and tragic sadness, 3)seeking newness with the reassignment of time and events. JobGeuk ShimChungWangWhoJeon is the first example of the transformation of ShimChungJeon's dramatic style and Devoted daughter ShimChungJeon is the first transformation of its scenario. These two works show how ShimChungJeon can be adapted to modern times and new cultures, and how ShimChungJeon can be made relevant and be enjoyed by the public regardless of the era.
