Researches using DEM are actively progressed in field of water resource, and especially the extraction of watershed and stream based on topographic and hydrologic analysis, is widely used in GIS analysis recently. However, because it is extracted that watershed which is type of sliver polygon and stream which is type of straight line in low topographic region, they're not efficient for application. This study determined buffer zone from stream and tried smooth elevation change to buffer zone in order to efficiently extract abnormal watershed and stream being occurred in low topographic region. Especially, we applied equal-distance assignment model using Voronoi Diagram to determine smooth elevation change. Also, we extracted watershed and stream using stream recognition DEM and origional DEM, and evaluated the efficiency of research through comparing the shape of watershed and stream in low topographic region.

Images of smoky make up illustrations with different the brightness tones for typical Korean eyes (standard one, small single eyelid and tailed up style) were systematically analyzed using vision-based emotional descriptive language for students majoring makeup and professional group. We identified that various images could be expressed by changing smoky makeup tones on eyes types through analysis of the emotional descriptive language. The smoky make up image recognition of smoky make up illustrations was almost consistent between the students and the professional group, but there was the distinct difference of image perception by two groups for some smoky make up illustrations due to the generation gap as well as their make up expertise and techniques. We suggested the image positioning maps which expressed the emotional reaction felt according to eyes shapes and smoky make up tones. The positioning maps were to provide criteria for various images to be able to express by smoky make up.

To understand morphological and genetic differentiation between Euphorbia esula and E. maackii we examined 12 morphological characters and 11 isozyme loci from 14 populations of two species. Species of E. esula complex (A = 1.63, P = 44.83, $H_e$ = 0.198) in Korea maintain nearly as high as the genetic diversity reported in East Asian E. jolkinii and E. fauriei while lower than those of E. ebracteolata and E. pekinensis in Korea. Although the ranges of most morphological character variation of the two species overlap, E. esula and E. maackii were well recognized by the combination of the morphological traits, and the result of UPGMA phenogram supports the two distinct species inhibited in Korea. However, isozyme data do not support the recognition of E. esula and E. maackii. The discordance between morphological and allozyme data should be explained by the recent divergence or gene flow via introgressive hybridization between two species.

A stem and root rot disease of kalanchoe (Kalanchoe sp.) which is a succulent plant that provides consumers with a durable flowering pot was found in Koyang, Kyounggi province, Korea in May 1998. We found that stems and roots of potted kalanchoe had dark brown spots at the soil level. The causal organism was identified as Pjytophtora nicotianae on the basis of mycological characteristics. The fungus produced markedly papillate, ovoid to spherical sporangia, and abundant chlamydospores. Sporangia were 20∼48$\times$24∼64㎛(avg. 35.0$\times$47.3㎛) in size, and optimum temperature for the mycelial growth of the isolate was 30$\^{C}$. The fungus showed relatively different pathogenicity to 14 kalanchoe cultivars including K. blossfelana cv. Florus. cultivars florsu, calypso, Maya, and Redsing were susceptible to thedisease in root dip inoculation. This is the first report demonstrating the stem rot on kalanchoe caused by P. nicotianae in Korea.

The adsorption characteristics of coffee were mvestigated at $5, 15, 25, and 35^{\circ}C$ under various water activities such as 11, 32, 57, 75 and 90% and prediction models were developed by optimization program. The moisture adsorption isotherm curves were similar to the typical sigmoid type. The values of equilibrium moisture content and the monolayer moisture content were highest in the Freeze Dried, which was due to porous structure by the drying method. In the result of adjusting the isotherm models in this paper, Halsey model generally gave the best fit for isotherms of coffee. Prediction model for equilibrium moisture content was established with water activity and temperature. Adsorption prediction models were also developed with water activity, with water activity and time, and with water activity, time and temperature, respectively.

In the era of neoliberalism with high rate of youth unemployment, young college students are forced to believe that the only way to enter the job market is by accepting and participating temporary off-campus apprenticeship, which often disguised as an internship for the creative culture and knowledge. This article discusses that the mode of off-campus apprenticeship, which is supposed to voluntary and participatory, bears in fact a strong resemblance with digital labor. Based on a series of in-depth interviews with college students, this study argues that the apprentice-typed labor denotes a process by which immaterial labor or free labor coincides with self-directed job training. Throughout the digital labor processes young college students are in a constant oscillation between precarity and hope, negotiating their autonomy and social conditions in the neoliberal work environment. The digital labor accumulates students' knowledge and information as a form of commodity, which in turn supports communicative capitalism.

천연기념물 제395호 진주 가진리 새발자국과 공룡발자국 화석산지는 1997년 5월 20일, 경남과학교육원 신축 공사장에서 당시 경남과학고등학교 교사로 근무하던 백광석(현재 서상중고등학교 교장)에 의해 최초로 발견되어, 수 백 점의 새발자국 화석과 공룡발자국 화석들이 학계에 알려지게 되었다. 지금까지도 세계 여러나라의 중생대 새 발자국 중에서 가장 밀도가 높은 화석산지로 손꼽히고 있으며 많은 학자들의 관심을 받고 있다. 이곳의 지질은 백악기 하양층군 함안층 하부의 적색 이암 또는 셰일과 사암의 호층으로 구성되어 있고, 새발자국 화석들은 적색 이암에서 발견된다. 현재, 이 화석산지는 경남과학교육원 건물 내부에 위치하고 있으며, '화석문화재전시관'이라는 명칭으로 보호 및 관리되고 있기때문에 자연재해와 풍화에 의한 침식을 1차적으로 막고 있다. 이 화석산지는 우리나라에서는 천연기념물 제394호 해남 우항리 화석산지와 함께 현장을 그대로 보존하면서 화석의 보존과 관리를 동시에 할 수 있는 건물을 지어 자연사교육을 진행할 수 있는 곳으로 많은 학생들을 대상으로 우리나라의 소중한 화석을 직접 관찰하고 학습하는 체험교육이 가능하다. 원격조종카메라 시스템을 활용하여 관람객이 직접 자신이 원하는 발자국 화석을 세부적으로 관찰할 수 있게 장치한 interactive system은 과학교육 효과를 증진시킨다. 선행 연구에 의하면, 본 화석산지에서 익룡의 발자국 화석(KS 071)도 공룡이나 새발자국과 같은 층리면에서 서로 겹쳐서 나타난다고 보고되었으나, 본 연구에 의해 다시 조사된 결과 전형적인 익룡의 발자국 화석에서 보이는 분명한 특징들을 발견할 수 없었다. 물갈퀴를 가진 새발자국 가운데에서 Uhangrichnus chuni 와 Jindongornipes kimi 로 기재된 표본들에 대하여서도 새롭게 분석하였다. Uhangrichnus chuni로 기재된 많은 표본들은 II-IV번 발가락 사이의 각, 물갈퀴의 형태, 뚜렷한 hallux 등의 형태적 특징을 근거로 할 때, 대부분이 Ignotorinis yangi로 판단된다. Jindongornipes kimi로 기재된 표본들은 이미 기재된 표본보다 크기가 적어도 10%-25%가 작으며, II-IV번 발가락 사이의 각에서 차이를 보인다.

A nuclear polyhedrosis virus isolated from the oriental tobacco budworm larvae, Helicoverpa assulta (Guenee) was characterized by electron microscopy, SDS-PAGE, restriction endonuclease analysis and cross infectivity. The shape of a polyhedron was $1.0\mu\textrm{m}$ in average with icosahdral outline, and the virus particle was $65nm\times300nm$ in average with rod-shape. The nuclear polyhedrosis virus was contained a single nucleocapsid within a viral envelope embedded in a polyhedron. The polyhedral protein was composed of a single polypeptide with a M.W. of 31 Kd. The genome size of the virus by restriction endonuclease analysis was about 120 Kb. Among several nuclear polyhedrosis viruses, the nuclear polyhedrosis virus from Helicoverpa assulta (HaNPV) and Autographa california nuclear polyhedrosis virus (AcNPV) were infected the oriental tobacco budworm larvae.

This study investigates the characteristics(form, material, structure, method of construction, vegetation) and model of lotus pond in Joseon Royal Tombs for conservation and restoration. The objects of study are the lotus pond of Namyangju Gwangreung, Hyoreung, Gimpo Jangreung and Sungreung that are well-preserved and the record is remaining. The form is two plane types, square shaped include an island and square shaped. The pond is 7.5~81m in width and 6.5~45m in length and the island is 8~16m in diameter. The depth of water is 0.5~1.2m and the cross section form is narrow bottom and wide top. The material of shore protection is soil in Hyoreung, Gimpo Jangreung and Sungreung. The bottom is mud in all sites. I think that the main material of the lotus pond in Joseon Royal Tombs is soil. The lotus pond is built by soil bank in the structure and method of construction. The water supply and drainage are worked through the culvert. There are many kinds of plants in the lotus pond today, however I think that the model of vegetation of lotus pond in Joseon Royal Tombs is lotus the inside, pine tree, fir tree and flowers the around and pine tree the inside of island in compared the present and the old literature. In comparison with the lotus pond in Joseon Royal Tombs and the lotus pond in the Joseon palace, the material is the biggest difference. The main material is soil in Royal Tombs but isodomic in Royal Palace. I think that the difference of material in between two causes the difference of structure and method of construction. The Royal Tombs is valuable in architecture, landscape and esthetics, this study investigated the characteristics and model of lotus pond in Joseon Royal Tombs. I think that this study serves as a momentum to find a traditional technique in Royal water space and offer the foundation to plan in the contemporary water space.

To develope a microbial pesticide for the control of mulberry longicorn beetle, Apriona germari, Beauveria spp. were isolated from the infected Apriona germari larvae. The morphology of Beauveria spp. was observed by phase contrast and scanning electron microscope. In addition, the Beauveria spp. isolated from Apriona germari were identified by the random amplification of polymorphic DNA using polymerase chain reaction. The results showed that the Beauveria spp., SFB-1A and SFB-3A, isolated from Apriona germari were identified with B. bassiana and B. brongniartii, respectively, suggesting that the random amplification of polymorphic DNA is effective for the identification of Beauveria spp.
