This study explores the political parody, which has become an active art form in order to express Korean Internet users' political practices, especially, during the politically turbulent periods from the presidential election of 2003 to the recent candlelight vigil protest of 2008. This study investigates the rise and fall of a parody culture by online users from the mid-2000s, and also examines aesthetical aspects of parodic artworks relying on amateurism culminated in 2004. Specifically, the current study questions an aesthetical lack shown in 'appropriation', by which most of the online users simply produce imitations of original image. This study rather notes 'photomontage' as an aesthetic prototype, the political aesthetics made by John Heartfield, through which this study intends to observe how his aesthetical legacy of political art could be realized in the contemporary form of political parodies produced by online users. The present paper concludes that online users' political participations in producing critical works of art could allow us to negate the dichotomy between the elite and the mass, professional artists and amateur parodists, and a radical politics and the politics of style.

Publication Industry of scientific technology is showing tendency of decreasing in sales, which clearly draws down curve since 2000. The printing culture is declining whether it is because of trend avoiding pure science or technological science and engineering, advancement of mass media or increasing frequency of using internet. Nevertheless, researcher considered car industry in publication industry as a life-long purpose for study. For this reason, the researcher tried to find the variables of the marketing which give impact on the customers such as student group and consumer who buys cars, when buying professional books. The found variables are expected to have a huge impact on the publication industry of professional books. As a result of research, in the area of the vision and motive, most said that they have "chosen a major in car because they liked car in usual base." In the stage of recognizing the problem, they buy the books when it is inevitably necessary. In the stage of searching for the information, they get information from advertisements, friends, professors, internet or sales clerk in book stores. In the stage of evaluation, they look for the title and the publication date of the books. In addition, in the stage of deciding purchase, "buy immediately" was the most frequent answer while impulsive purchase is the least frequent answer. In the stage of evaluating after purchase, many of them mostly are satisfied with their purchase.

The main cause of DMSMS is the rapid replacement cycle and short life cycle of parts, according to the development of science, compared to the long life cycle of weapons systems. In particular, the problem of the supply and demand of such parts becomes even more acute during the operation maintenance phase after the mass production and power generation stage. To eliminate DMSMS problems that arise continuously from development to the operation of weapon systems and select the most cost-effective countermeasures to obsolescence, this paper suggests a standard to determine the appropriate time for quantitative performance improvement by conducting total life cycle cost analysis. For such purpose, this study examined the domestic and overseas cost analysis methods and applied it to single domestic weapon system to verify the research. This study responds to the issue of discontinuing components and helps reduce the total life cycle cost of military products.

조미료란 식품을 조리, 가공, 섭취할 때 맛을 증진시키거나 강화시킬 목적으로 사용되는 물질을 일컫는다. 발효, 종합 및 천연계 조미료의 국내외 시장동향에 대해 살펴보고, 조미료의 향후 발전방향과 중점 연구 분야, 관련업계의 연구개발 동향에 대한 고찰을 토대로 조미료 분야의 고부가가치 산업으로의 육성방안에 대해 알아보았다. 미원, 아이미 등으로 대표되는 발효조미료의 내수시장은 성숙기를 거쳐 소폭 감소세를 보이는 쇠퇴기에 접어들고 있다. 이는 소비자의 MSG에 대한 기피현상이 주 원인으로 판단된다. 전반적으로 품질 차별화 없이 가격 경쟁이 심화되고 있는 실정이다. 국내 종합조미료 시장은 1975년 국내에 처음으로 CJ에서 다시다 제품을 출시한 후 대상에서 1982년 맛나, 1988년 감치미를 출시하면서 30여 년간 지속적으로 성장해 왔다. 현재 시장규모는 2천억원에 이르고 있으며 최근 들어서는 성장세가 완만해지고 있고 가정용은 거의 정체되어 있다. 일본 조미료 시장은 발효조미료, 종합조미료 그리고 다양한 조미식품의 소재로 활용되는 천연조미료로 구분할 수 있다. 발효조미료 시장은 국내와 비슷한 상황으로 전체적인 물량변화는 약간 감소하는 경향이며 생산기지의 해외이전 현상이 뚜렷하다. 종합조미료 시장은 한국과 유사한 풍미조미료 외에도 보다 전문화되고 다양한 형태의 조미료가 시판되고 있으며, 전통적인 풍미조미료는 정체현상을 보이고 건강지향, 전용화 조미료가 호조를 보이고 있다. 일본과 한국의 조미료 발전 단계는 조금 차이를 보이고 있다. 현재 한국은 종합조미료 시대에서 용도별 조미료 시대로 넘어가는 단계에 있는 반면, 일본은 이미 메뉴 전용 조미료시대에 접어들었고, 건강, 기능성을 강조하는 시대로 나아가고 있다. 이들 변화는 건강에 대한 소비자의 관심과 그로 인한 보다 천연에 가까운 조미소재에 대한 수요, 동시에 맛에 대한 충족까지 요구하는 시대적 변화에 따른 필연적 결과로 보인다. 미래의 조미료는 천연계 소재의 사용량이 증가할 것이고, 소비자의 건강, 안전 추구심리에 부흥하여 안전성과 기능성을 부여하는 소재에 관심이 집중될 것으로 보인다. 더불어 전반적인 생활수준 향상에 따라 제품의 고급화와 전용화도 진행될 것으로 보인다. 향후 조미료시장을 주도할 각 현상에 대해 좀더 자세히 알아보고 학계 및 업체의 최근 연구동향과 제품개발 현황에 대해 고찰해 보았다. 기술연구 동향을 보면, 나노 기술에 의한 조미신소재연구, 초미분쇄기술, 미세 캡슐화 기술, 생물공학 기술이 활용된 발효 및 효소분해에 의한 펩타이드계 조미소재 개발 등이 활발하게 진행되고 있다. 선진업체 연구 및 제품개발 동향은 아지노모트/교와의 ''코쿠미''계 조미소재 연구개발, 일연푸드/동해물산의 천연 엑기스계 조미소재 연구개발, 보조주(주)의 주류 조미료 개발 위주로 살펴보았다. 조미료 시장의 발전 과정과 선진 업체들의 연구, 개발동향을 종합해 보면 첫째는 천연 건강지향에 부응하는 차별화된 소재 및 기능성 소재 개발이고 둘째는 맛과 편리함의 추구에 대응하는 메뉴 전용화 추세이다. 이를 위한 기술적 연구도 기능성 소재(히스티딘 함유 디펩타이드)개발, 나노기술, 미세캡슐화 기술 등을 통하여 다양하게 진행되고 있다. 조미료 산업을 첨단 고부가가치 산업으로 육성하기 위해서는 R&D 투자확대와 효율성을 제고하는 것이 필수적이다. 각 기업단위에서는 장기적 차원에서 첨단식품 기반기술에 대한 연구를 수행하거나, 전문 중소기업, 벤처를 육성하는데 지원해야 한다. 그러나 현실은 당장의 수익과 회사간 경쟁으로 인해 장기적 투자, 사회적 인프라 육성 등에는 관심을 쏟지 않고 있다. 조미료를 비롯한 식품에 관련된 기술들이 다양한 기초연구와 응용기술, 개발연구 등의 총합인 경우가 많기 때문에 이들 상이한 연구 분야간의 연계를 강화하고 개발된 기술의 이전, 확산체계를 구축할 필요가 있다. 이를 위해 기업간 수평적 네트워크 외에도 국가기관이 참여하는 연구 자원의 효율적 집행 기관이 필요하리라 본다.

An analysis of tree ring series of a lace-bark pine (Pinus bungeana Zuccarini) was carried out to find out the exact age of the tree, to describe life history of the tree affected by the change of past environmental factors, and to explain the relationships between the growth fluctuation of the tree and the change of environmental factors of the past. This study explicitly showed that the tree was about 300 years old in 1992 and that the previous estimate of the age to be about 630 years old has no ground to be justified. This was also ascertained by the close correspondence of the tree growth fluctuation to the fluctuation of soil moisture related environmental factors for the last 80 years in Seoul. Although it is clear that the tree suffered from slow growth for about 30 years initiating from the 1910s, it is not sure whether the soil moisture deficits or droughts during the years of 1910-1913 played a major role in causing the decline of the trees afterwards. Discussion was further extended for defining active roles for the Cultural Properties Administration of Korea in management and research to effectively protect the Old and Big Trees under the category of Natural Monument of Korea.

The purpose of this study is to clarify the reason of the change of production-and-marketing system and of the regional division. The data for this study were collected by administering interviews with people engaging in hemp fabric industry: namely, craftsmen and managers in the production and marketing of "hemp fabric" handcraft. The summary of this study is as follows: First, the hemp fabric industry is a main subsidiary business of agriculture in Andong. The process of making hemp fabric heavily depends on manual labor. The process is divided into five stages: namely, cultivating hemp, pre-reeling, reeling, weaving, and colouring. Second, Andong "hemp fabric" handicrafts industry had been continuously growth until the late 1960s. During the period of Japan colonization, it was under boom condition: while the other traditional fabric industries were declined. In the 1970s, the decrease of the demand of hemp fabric was the result of mass production of substitute goods on factory system: while, in the 1980s, the growth of per capital income play an important role in bringing about the increased demand of hemp fabric. Third, in the 1980s. production-and-marketing system was changed as the result of the effort to improve the quality and the process, the advanced age of craftsmen, and the weak function of existing marketing systems. The social division of labor within the district is well developed between cultivating hemp, reeling and weaving. The social division of labor is also found in the partly process of handcratfs, and between the production and marketing. The social division of labor between production and marketing is not strongly developed to establish a reliable enterprise that develops a new product and opens a new market. Fourth, the spatial boundary of the production of hemp fabric handcrafts becomes limited into a special region based on the regional specialization of hemp cultivating and the differentiation of utilization of labor.

This study conducted a survey on the time serial change in the aging ratio and population structure in new towns and their housing complex of Korea and Japan, and revealed the differences in the factors that affect the aging ratio in new towns of Korea and Japan through a comparison of the housing provision of housing complex with a high aging ratio. Rapid aging is underway around the housing complexes that were developed in the beginning of Tama new town in Japan. Agingtends to increase in proportion to the opening time of the housing complex. Rental housing residents of early migration households showed rapid aging because they had generation separation early due to narrow housing. On the other hand, Bundang new town maintains a lower aging ratio and speed than Seoul and Seoul metropolitan area due to the constant influx of student population. On the other hand, aging is more likely to increase in large houses due to the depression of the real estate market.

Urban areas are variously under threat including deterioration of ecological functions. Many pond wetland types have been created as part of an effort to improve and restore this urban environment. This study was arranged to examine improvement plans of wetlands in urban areas by analyzing semi-natural wetlands in farm areas. As for environment for water quality, it suggested the inflow of natural water neighboring rivers or the direct inflow of rain as the improvement plans. The result which analyzed soil pH, OM, and T-N content of the soil environment mentioned that urban areas supplied artificial sluices, removed apoptotic bodies, and used artificial soil and waterproofing materials and use of natural materials in design and construction, the sluice state of the natural form, and negligence of autumn plants were suggested as the improvement plans. Florae appeared in the subject sites of the study have found that there are 35 families 69 species in urban areas and 53 families 142 species in rural areas. As the average has found that there are 18.5 families 29.3 species in 4 urban areas and 26.3 families 53.5 species in 4 rural areas, the big difference between them was analyzed. As the cause has found that there are differences in yearly plants in farming areas when compared to urban areas, creation of various basic environments including soil and water quality was suggested to make yearly plants settle down widely. Naturalized plants have found that there are no big differences between urban areas and rural areas. However, the average of the naturalized ratio in urban areas is 17.4% as the naturalized plants are about 1/4 of the appeared plants. As it was analyzed to be higher than 7.7%, the average of the naturalized ratio in farming areas as the big difference, creation of various inhabiting environments was suggested to make more yearly plants appear like the analyzed result of the life type. Consideration of placement, materials, and inhabiting environments was suggested to make creation of wetlands well appreciated to improve functions of wetlands in urban areas. It is expected that the above results of the study will be utilized in creation and improvement of the pond wetlands which can play a huge role in increase and improvement of biological diversity in urban areas.

This study analyzed the density and mortality rate of Korean fir at 9 sites where individuals of Korean firs were marked into the live and dead trees with coordinates on orthorectified aerial images by digital photogrammetric system. As a result of the analysis, Korean fir in each site showed considerable heterogeneity in density and mortality rate depending on the location within site. This make it possible to assume that death of Korean fir can occur by specific factors that vary depending on the location. Based on the analyzed densities and mortality rates of Korea fir, we investigated the correlation between topographic factors such as altitude, terrain slope, drainage network, solar radiation, aspect and the death of Korean fir. The density of Korean fir increases with altitude, and the mortality rate also increases. A negative correlation is found between the terrain slope and the mortality rate, and the mortality rate is higher in the gentle slope where the drainage network is less developed. In addition, it is recognized that depending on the aspect, the mortality rate varies greatly, and the mean solar radiation is higher in live Korean fir-dominant area than in dead Korean fir-dominant area. Overall, the mortality rate of Korean fir in Mt. Halla area is relatively higher in areas with relatively low terrain slope and low solar radiation. Considering the results of previous studies that the terrain slope has a strong negative correlation with soil moisture and the relationship between solar radiation and evaporation, these results lead us to infer that excess soil moisture is the cause of Korean fir mortality. These inferences are supported by a series of climate change phenomena such as precipitation increase, evaporation decrease, and reduced sunshine duration in the Korean peninsula including Jeju Island, increase in mortality rate along with increased precipitation according to the elevation of Mt. Halla and the vegetation change in the mountain. It is expected that the spatial patterns in the density and mortality rate of Korean fir, which are controlled by topography such as altitude, slope, aspect, solar radiation, drainage network, can be used as spatial variables in future numerical modeling studies on the death or decline of Korean fir. In addition, the method of forest distribution survey using the orthorectified aerial images can be widely used as a numerical monitoring technique in long - term vegetation change research.

Within the Boseong-Jangheung area of Korea, five hydrothermal gold (-silver) quartz vein deposits occur. They have the characteristic features as follows: the relatively gold-rich nature of e1ectrurns; the absence of Ag-Sb( -As) sulfosalt mineral; the massive and simple mineralogy of veins. They suggest that gold mineralization in this area is correlated with late Jurassic to Early Cretaceous, mesothermal-type gold deposits in Korea. Fluid inclusion data show that fluid inclusions in stage I quartz of the mine area homogenize over a wide temperature range of 200$^{\circ}$ to 460$^{\circ}$C with salinities of 0.0 to 13.8 equiv. wt. % NaCI. The homogenization temperature of fluid inclusions in stage II calcite of the mine area ranges from 150$^{\circ}$ to 254$^{\circ}$C with salinities of 1.2 to 7.9 equiv. wt. % NaCI. This indicates a cooling of the hydrothermal fluid with time towards the waning of hydrothermal activity. Evidence of fluid boiling including CO2 effervescence indicates that pressures during entrapment of auriferous fluids in this area range up to 770 bars. Calculated sulfur isotope composition of auriferous fluids in this mine area (${\delta}^34S$_{{\Sigma}S}$$\textperthousand$) indicates an igneous source of sulfur in auriferous hydrothermal fluids. Within the Sobaegsan Massif, two representative mesothermal-type gold mine areas (Youngdong and Boseong-Jangheung areas) occur. The ${\delta}^34S values of sulfide minerals from Youngdong area range from -6.6 to 2.3$\textperthousand$ (average=-1.4$\textperthousand$, N=66), and those from BoseongJangheung area range from -0.7 to 3.6$\textperthousand$ (average=1.6$\textperthousand$, N=39). These i)34S values of both areas are comparatively lower than those of most Korean metallic ore deposits (3 to 7TEX>$\textperthousand$). And, within the Sobaegsan Massif, the ${\delta}^34S values of Youngdong area are lower than those of Boseong-Jangheung area. It is inferred that the difference of ${\delta}^34S values within the Sobaegsan Massif can be caused by either of the following mechanisms: (1) the presence of at least two distinct reservoirs (both igneous, with ${\delta}^34S values of < -6 $\textperthousand$ and 2$\pm$2 %0) for Jurassic mesothermal-type gold deposits in both areas; (2) different degrees of the mixing (assimilation) of 32S-enriched sulfur (possibly sulfur in Precambrian pelitic basement rocks) during the generation and/or subsequent ascent of magma; and/or (3) different degrees of the oxidation of an H2S-rich, magmatically derived sulfur source ${\delta}^34S = 2$\pm$2$\textperthousand$) during the ascent to mineralization sites. According to the observed differences in ore mineralogy (especially, iron-bearing ore minerals) and fluid inclusions of quartz from the mesothermal-type deposits in both areas, we conclude that pyrrhotite-rich, mesothermal-type deposits in the Youngdong area formed from higher temperatures and more reducing fluids than did pyrite(-arsenopyrite)-rich mesothermal-type deposits in the Boseong-Jangheung area. Therefore, we prefer the third mechanism than others because the ${\delta}^34S values of the Precambrian gneisses and Paleozoic sedimentary rocks occurring in both areas were not known to the present. In future, in order to elucidate the provenance of ore sulfur more systematically, we need to determine ${\delta}^34S values of the Precambrian metamorphic rocks and Paleozoic sedimentary rocks consisting the basement of the Korean Peninsula including the Sobaegsan Massif.
