  • Through MIRIS $Pa{\alpha}$ Galactic plane survey, a lot of $Pa{\alpha}$ blobs were detected along the plane. To reveal their characteristics, we are planning to collect NIR high-resolution spectroscopic data for them by using Immersion GRating INfrared Spectrograph (IGRINS). Here, we present the preliminary results of the IGRINS observations for a Herbig Be star, MWC 1080, which is one of the $Pa{\alpha}$ blobs detected in Cepheus. This Herbig Be star is known to possess a lot of young stellar objects (YSOs) and bright MIR ($10-20{\mu}m$) nebulosity in its vicinity. From IPHAS $H{\alpha}$ data, we revealed large extended $H{\alpha}$ features that correlate well with MIR and 13CO morphologies around MWC 1080. A part of the $H{\alpha}$ features shows a bow shock shape to the northeast of the primary star MWC 1080A, which seems to be due to an outflow from MWC 1080A. Through IGRINS observations, we detected faint [Fe II] ${\lambda}1.644{\mu}m$ and H2 1-0 S(1) ${\lambda}2.122{\mu}m$ emission lines around the bow shock feature. Interestingly, to the east region of MWC 1080A, we also detected strong [Fe II] and H2 emission lines with a couple of velocity components, which suggests the detection of a new outflow from another YSO. Broad $Br{\gamma}$ ${\lambda}2.1662{\mu}m$ line and H2 lines with various velocity components were detected around the bright MIR and $H{\alpha}$ nebulosity as well.

  • In this paper, as a forecasting method, the market survey for forecasting demand is introduced for the estimation of subscriber line demand in the optical access networks. The market survey method for the new multimedia services is attempted to collect information directly from customers using the questionnaires for home-users and business-users in local loops. Analysis rationale of questionnaires is suggested to estimate the number of subscriber lines. Also, two measures are presented to quantify the credibility on survey responses; one is the probability that the customer will use the multimedia services and the other is the rate that the subscriber line demand will be actually realized. The former measure is calculated based on the information on customers and the Logit analysis. The latter is obtained by the degree of customer's knowledge about specific services and the customer's willingness to use the services. Based on the values of two measures, the number of subscriber line demand can be developed for installing the optical access networks.

  • 벼 도열병은 안정적인 쌀 생산을 위협하는 대표적인 병으로, 도열병 방제에는 저항성 품종의 육종이 가장 효과적으로 이용되었다. 병원균의 꾸준한 수집과 이들을 이용한 저항성 검정 테스트는 신품종 육성 프로그램에서 중요한 과정이다. 1985년 이래 우리나라의 도열병균은 8개의 판별품종을 이용한 레이스 판별시스템을 구축하여 분류하였다. 그러나 기존의 판별품종은 유전자형이 연구된 바 없어 새로운 레이스 출현이나 병 저항성 붕괴 등에 대하여 과학적으로 분석하여 신속하게 대처하기가 어려웠다. 따라서 이 연구에서는 유전자형이 밝혀진 단인자 저항성 계통과 우리나라에서 수집된 200개 균주의 병원성 반응을 분석하여, 새로운 판별 품종 시스템의 필요성을 제시하였다. 또한, 24개의 단인자 저항성 계통의 병원성 반응을 통해 9개의 대표 저항성 유전자를 선발하였으며, 이에 따른 10개의 대표균주 그룹과 그 저항성 반응을 인덱스화 하고 30개의 한국형 대표균주를 선발하였다. 이 연구는 향후 도열병 저항성 검정 및 벼 신품종 육종에 기초자료로서 활용될 수 있을 것이다.

  • Objectives: This study aimed to assess the environmental factors that affect particulate matters (PM10) and to compare with outdoor PM10 concentrations in an underground subway stations. Methods: The PM10 level was determined from May 2013 to September 2013 in the Seoul subway stations in four lines. PM mini-vol portable sampler sampler was used to collect PM10 for 6 hrs. Arithmetic means of PM10 concentrations with standard deviation (SD) were calculated. Paired t-test was used to compare the differences between indoor PM10 and outdoor PM10 concentrations with correlation analysis which was used to identify the association between indoor PM10 concentrations and environmental factors. Results: There were no different PM10 concentrations significantly between line 1, 2, 3 and 4 in an underground subway stations. Passenger number was positively associated with PM10 concentration while construction year was negatively associated with PM10 concentrations. Indoor PM10 concentrations were significantly higher than those in outdoor PM10 concentrations. PM10 concentrations were higher in the stations which were constructed before 1990s rather than the stations constructed after 1990s. Conclusion: PM10 levels in the underground subway stations varied greatly depending on the construction year. Therefore, it might need to be more careful management to the stations which constructed in before 1990s.

  • Frank Lloyd Wright, a master of the 20th Century Ar-chitecture, contributed tremendously in creating a wholly new form of American architecture called Prairie Style. His idea behind the development of the building structur-al system, organic relationships between inner and outer space, horizontal vertical lines, and idea of extending and expanding interior spaces came from nature. He had completed over 390 projects throughout his life and 90% of those projects were residential design. The most typical characteristic shared by many of his residential design was that each design element, whether it is functional or aesthetical, has close relationship to or-ganic nature, human scale, theoretical floor plants, and maximum emphasis on horizontal lines in respect to na-ture. His concept of "flow of spaces" reformed common the-ory of room next to room in a enclosed space. His sense of "wall" was no longer the side of a box. Careful selec-tion of finishing materials, colors, and natural images en-hance the design as well. F.L. Wright was an artist, designer, and architect who believed the exterior space should have direct relationship to the interior space. His architectural philosophy was not only to design exterior of architecture but also to ful-fill his space through the careful development of interior elements such as furniture, and lighting fixture. Even the patterns for leaded glass windows were designed to have unified appearance from outside to inside of the house. The objective of this study was to analyze floor plans, spatial organizations, and interior design elements of the houses which represent the best of F.L. Wright's design principles and philosophy behind Prairie Style. The meth-od used to collect informations for this study was based on books, articles, journals, and actual site visits. actual site visits.

  • The purpose of this study was to find out the traditional decoration techniques in the Korean costume. Both quantitative and qualitative research methods were used to collect and investigated the traditional decoration techniques used in the related literatures and museum catalogues. The results were as follows. The broad and back stitching are fundamental stitching, which used to Nubi and Keki. Top stitching applied broadly to the Korean costume, for example, Jergori, Wonsam, Jeonbok, Beosun, Bojagj and so on. The expression techniques for top stitching were one, two or three stitches. When the top stitching was used as colorful stitches, they were more decorative. The Zatmulim was used for the decorative effect on the seam line because it was triangular shaped and became more effective by changing the rotor and size. Sunmulim was used on the narrow line such as the seam lines of Gergori and Chima. The bakchi decoration was imitating a bat shape, had a meaning of bringing the goodness and gave the tiny and elaborated image. It was used to the neckline of Geogori, seam line of Chima, Pungcha Bazi and so on. Sattgi was used to attaching the bottom of two stiff fabrics adopting for Beosun, Ayam and Norigae. When it used colorful strings, the more decorative effect was added. The knot for button used the fabric instead of buttons and applied to the Cheonlik, Gergori. The aesthetic values of the traditional decoration techniques in the costume were both natural beauty and practicality with creativity.

  • Persons who are waiting for decision of the court concerning whether they are guilty or not after they are involved in the criminal case and detained in the special institution isolated from society, will desire to de found innocent and acquited or to be slightly punished. Inmates are the suspected persons and the accused persons who are detained in the correctional institution. They have the right to de assisted by lawyes in order to receive the favorable verdict in the court. However, the right of the poor and the ignorant, in reality, cannot be perfectly protected due to the imperfection and defect of the defense counsel system itself and its application. Therefore, as a means to guarantee the so-called access to the court, the fundamental constitutional right, the law libraries are established and the legal information services are provided to the inmates within the correctional institution in the advanced country such as the United States. In addition, the judicial precedent and the various kinds of professional organizations provide the managerial guide-lines for such libraries to enoughly collect materials and to provide the effective information services to the inmates. In order to furnish the management of the correctional institution of Korea with useful information, the legal information services, materials collected, and information service personnel of the law libraries within the correctional institution are minutely examined in this paper.
