"Dokseoyeoga Do"(An Enjoyable Pleasure with Reading) is a work included in a collection book of both poems and works called as "Gyunggyo Myungseung Cheop"(Collections of Beautiful Scenary in the Suburb of Seoul) with a promise that a great painter Gyumjae Jung-Sun(謙齋 鄭敾) and his lifelong friend, Sacheon Lee Byung-Yeon(李秉淵) should hopefully exchange their poems and painted works. So far, general perspective of art history toward this work is either self-portrait of Gyumjae himself or genre painting of the aristocrat. The purpose of this study is to interpret in-depth meanings implied in this work with various considerations of plant elements appeared in this work. As a result of this study, We could draw newer and additional meanings beyond the existing perspectives of art history research categories, and the details can be summarized as following below. First of all, we could approach a new interpretation implying that Gyumjae and Sacheon hopefully wished their well-being, friendship, and reunion. Second, as a means of expressing this meaning, plant elements like old juniper(Juniperus chinensis L.), orchid(Orchidaceae), and peony(Paeonia lactiflora var. hortensis) were used. Third, each plant element can be literally seen as an icon implying message that Gyumjae desired to give to Sacheon. To be more detailed, experience and greenness of old juniper imply well-being of two people, and orchid implies fragrant friendship, and peony implies the feeling that Gyumjae hopefully desired to make a reunion with a parted friend. The significance of this study is that throughout old paintings, we could observe substantial examples of recognizing the meanings of plant elements in a category of traditional landscaping and utilizing them. Moreover, adding various point-of-views of many professional categories like Korean Landscaping history in the traditional painting research, we could also recognize the potentials for making rich interpretation toward implicated meanings of old paintings.

This article is for considering and looking through the meaning of Classic of Poetry(Shi jing) Hiku-ka of Kobayashi Issa before reviewing and adapting Classic of Poetry(Shi jing) in Eastern Asia. Issa wrote his works by using Hyanghwa-Gucheop in 1803, and he had adopted it as his creative works of Hikai absorbing Classic of Poetry(Shi jing) for about half a year. There has been no national study about this so far, and this study covered the aspects of Issa's adapting way of Classic of Poetry(Shi jing) in Japan and China. There have been several problems that the contents were limited to Guo-feng and there were no agreement of terminology as well among researchers. To overcome these limitations, therefore, this article aimed at all the works, rejected the view point as just a translation, and denominated this study as Haiku-ka. Above all, this study looked though Issa's Classic of Poetry(Shi jing) by splitting the aspects of Haiku-ka into borrowing topics and materials. In borrowing topics, the works with the topics of homesick and nostalgic parents stood out. Furthermore, annotations and understandings of Issa's original works were deeply involved. In borrowing materials, the original meanings in the works were transformed and changed or even reinterpreted by their own way. Eliminating sublime emotions, furious tone, and condemnation was main characteristic of Haiku-ka in Classic of Poetry(Shi jing). Besides, there were ways of exclusion of reasoning, deviating from the viewpoint of Sigyo(edification by poetry), not including moral senses. In other words, Issa used habits and impressions like the way of Haiku when he was doing Haiku-ka in Classic of Poetry(Shi jing). The meaning that Issa's Hiku-ka of Classic of Poetry(Shi jing) stood out compared to adaptation of Classic of Poetry(Shi jing) in Eastern Asia. Although Classic of Poetry(Shi jing) in Vietnam was transferred in the form of the poem in Vernacular, the meaning and contents were not changed. Moreover, the original works and characters in Joseon were not destroyed because Classic of Poetry(Shi jing) was not liberally translated but literally. However, Issa transferred the Classic of Poetry(Shi jing) in the form of the poem in Vernacular to reveal the value of popular ballads. This was a different adapting way of Classic of Poetry(Shi jing) from that in Eastern Asia.

The Paintings of a 60^th Wedding Anniversary Ceremony Created by an Unknown Painter (Deoksu 6375), housed by the National Museum of Korea, is a five-panel painting book depicting scenes from a wedding ceremony. Hoehonrye is a type of repeated wedding ceremony to commemorate a couple's 60th wedding anniversary with congratulations from the community. The paintings of the book record five scenes from the wedding: jeoninrye, a ceremony where the groom brings a wooden wild goose to the bride's house; gyoberye, the groom and the bride bowing to each other; heosurye, pouring liquor to toast to the couple's longevity; jeopbin, offering tea to guests; and a banquet to celebrates the couple's 60th wedding anniversary. The book describes figures, buildings and a variety of items in detail with delicate brushstrokes. The techniques were examined using microscopy, infrared, and X-ray irradiation and hyperspectral imaging analysis. The invisible parts were examined to identify the rough sketch and distinguish pigments and dyes used for each color. The components of the pigments were determined by X-ray fluorescence analysis, while the dyes were identified by UV-vis spectrometry. Microscope observation revealed that the fabric used for the paintings was raw silk thread with almost no fiber twist, and plain silk fabric. Hyperspectral imaging analysis, X-ray fluorescence analysis, and UV-vis spectrometry confirmed that the white pigment was white lead and the black was chinese ink. The red pigments were using red clay, cinnabar, and a mixture of cinnabar and minium. Brown was made using red clay and organic dyes, and yellow using gamboge. Green was identified as indigo, malachite, chrome green, barium sulfide, and blue as azurite, smalt, and indigo. The purple dye was estimated as a mixture of indigo and cochineal, and gold parts were used gold powder. Hyperspectral images were distinguished parts damaged and conservation treatment area.

Researches in text categorization have been confined to whole-document-level classification, probably due to lacks of full-text test collections. However, full-length documents availably today in large quantities pose renewed interests in text classification. A document is usually written in an organized structure to present its main topic(s). This structure can be expressed as a sequence of sub-topic text blocks, or passages. In order to reflect the sub-topic structure of a document, we propose a new passage-level or passage-based text categorization model, which segments a test document into several Passages, assigns categories to each passage, and merges passage categories to document categories. Compared with traditional document-level categorization, two additional steps, passage splitting and category merging, are required in this model. By using four subsets of Routers text categorization test collection and a full-text test collection of which documents are varying from tens of kilobytes to hundreds, we evaluated the proposed model, especially the effectiveness of various passage types and the importance of passage location in category merging. Our results show simple windows are best for all test collections tested in these experiments. We also found that passages have different degrees of contribution to main topic(s), depending on their location in the test document.

This research is an introductory study that hopes to interpret the cultural scenic landscape by analyzing Korea's mountains, streams, topography, color, light, human behavior, and more based on real landscape paintings. It places its purpose on understanding our intrinsic cultural scenic landscape by investigating the changed topography and the differing life patterns caused bythe active national land development after the modern era. With Seoul, which is now difficult to find images of its past, and the surrounding areas of the Han riverbed, the interpretation related to its original topography, landscape, climate, weather, and human behaviors was observed while the main focus was placed on the climate of the perception held by people regarding Mt. Geumgang and other ranges which are not fully opened to the public yet. In order to comprehensively analyze the figures of features and appearing landscapes including color, light, and more, it was described through the concept called climate. Hereupon, the real landscape paintings by Gyunjae(Jeong-Seon), mainly bearing features of existing Korean mountains, wereutilized as visual historical material. However, not having all his works, other pieces with representative characteristics were utilized such as "Gyeong-Gyo-Myeong-Seung-Chup(a painting with picturesque sceneries around old Seoul)" and "Hae-Ak-Jeon-Shin-Chup(a landscape painting including even the spirits of the seas and mountains)" which contain the regions' distinct scenery. As a result, the old cultural scenic landscapes of Korea are regarded as containing diverse mountains and where the conceptions of the treatment of mountains were reflected.

This paper briefly describes the KITSAT-1 and KITSAT-2 spacecrafts and presents the functions, calibration procedures and in-orbit results of the KITSAT-2 analog sun sensors have been flown as an experimental payload for the future mission. We have two constraints in their design: small size and very low power consumption due to the tight mass and power budget of the spacecraft. Two one-dimensional analog sun sensors are mounted on the top facet of the KITSAT-2 spaceraft. Each has $\pm$60 degrees of view angle and they cover 210 degree field of view in total as the 30 degree view angles are overlapped. Only the relative sun angle around the Z-axis (yaw-axis) and the spin rate of the spacecraft can be achieved as the one dimensional sun sensors are used and they are aligned with the Z-axis. The calibration formulae are obtained using the fifth order line fitting algorithm for each sun sensor on the ground and they are applied to the obtained in-orbit data. ASS-1 with silicon solar cells has maximum error of 1.5 degree and ASS-2 with silicon photocells manufactured at KAIST has maximum error of 0.5 degree except near 0 degree of sun ray incident anagle where random reflection of incident sun ray is maximum in orbit. The results are presented in chapter 4. The performance of each sun sensor and the possible mounting errors are stated in chapter 5.

In this paper, we showed the applicability of power symmetric MSSI(Mid-Span Spectral Inversion) to the long-haul WDM system with the channel interference due to FWM(Four Wave Mixing). And we showed the degree of performance improvement. We used 1 dB EOP(Eye-Opening Penalty) criterion so as to evaluate the degree of compensation dependent on the variation of chirp parameter of optical pulse for the various input power in high speed tansmission system. And we evaluated the maximum input power of channel be able to be the signal to crosstalk noise (SNR) above 20 dB in the transmission link with the channel interference due to FWM. Consequently the proposed MSSI compensation method is capable to transmitting the total 68 WDM channels simultaneously with a 0.4 nm channel spacing and 5.3 dBm maximum input power in a 10 Gbps transmission link. Therefore the proposed power symmetric MSSI compensation method may be very useful for the implementation of long-haul wideband WDM transmission systems with relatively high power and improved performance.
