글로벌 게임시장의 성장에 따라 국내 게임이용자도 손쉽게 다양한 국가에서 접할 수 있게 되 었다. 그리고 이러한 글로벌 경쟁 속에서 현실의 다양한 문화 창의적으로 반영한 게임이 점증 하고 있다. 대표적인 것이 중국의 호요버스가 개발한 해제 월드 형<원심>으로, 해당 콘텐츠는 캐릭터와 공간디자인에 다양한 국가의 문 것이 특징이다. 이때 의상디자인은 캐릭터의 성격과 매력을 효과적으로 이국적인 특색을 드러내는 기호라는 점에서 특히 중요하다. 이에 이 글은 먼저 캐릭터 의상과 의상 기호에 관한 검토하고, <원심>의 문화 활용 전략을 간단히 살펴보았 다. 이후 퍼스의 기호학을 활용해 중국의 문화적 특색을 반<원신> 캐릭터 ‘운근’을 분석하였다. 분석 결과, <원신>의 캐릭터 디자인전략은 중국의 풍부한 문화적 문맥을 중심 코드를 적극적으 로 빌리는 한편, 캐릭터 성을 부각하는 방향으로 의상 구성요소를 변형 시 나타났다. 이후 분 석 결과를 바탕으로 차후 연구를 위한 발전 방향을 제시하였다..

A 13-year-old mixed dog was referred to the animal medical center, Gyeongsang National University. Lung masses were diagnosed at the left cranial and caudal lobes through diagnostic imaging, and consequently, left pneumonectomy was performed using a self-cutting linear endoscopic stapler. The pulmonary arteries, veins, and bronchus of each lung lobe were sealed and resected at once, and any air leakage or bleeding was not observed after the surgery. Compared to the conventional ligation method, the self-cutting linear endoscopic stapler has the advantage of significantly reducing the operation time and enabling simple and reliable sealing.

The increase in temperature due to climate warming is predicted to affect crop yields in the future. Until now, various types of OTC (open top chamber) that simulate the future climate condition have been developed and used to study the effect of temperature increase due to global warming on maize growth. However, in most OTCs, high equipment and maintenance costs were required to artificially increase the temperature. This study was carried to develop a cost-effective and simple OTC suitable for climate warming experiments for forage maize. Three octagonal OTCs with a height of 3.5 m × a diameter of 4.08 m and a partially covered top were constructed. The lower part of OTC covered film was opened at a height of 26 cm (OTC-26), 12 cm (OTC-12) from the ground surface, or not opened (0 cm, OTC-0). Mean air temperatures during the daytime on a sunny day in OTC-0, OTC-12 and OTC-26 increased to 3.23℃, 1.33℃, and 0.89℃, respectively, compared to the ambient control plot. For a pilot test, forage maize, ‘Gwangpyeongok’ was grown at OTCs and ambient control plots. As a result, in the late maize vegetative growth phase (July 30), the plant height was increased more than 45% higher than the ambient control plot in all OTC plots, and the stem diameter also increased in all OTC plots. These results indicate that it is possible to set the temperature inside the OTC by adjusting the opening height of the lower end of the OTC, and it can be applied to study the response of forage maize to elevated temperature. An OTC, with its advantages of energy free, low maintenance cost, and simple temperature setting, will be helpful in studying maize growth responsiveness to climate warming in the future.

We aimed to predict the Italian ryegrass (IRG) productivity change of introduced and domestic varieties based on climate factors and identify suitable areas for IRG cultivation using the RCP 8.5 scenario. The minimum mean air temperature in January showed the highest correlation with productivity. The ratio of possible and low productivity areas was high in Gangwondo, and the ratio of suitable and best suitable areas was relatively high in the central and southern regions in the past 30 years. The change in the IRG cultivation area was found to be 26.9% in the best suitable area between 1981–2010 but increased significantly to 88.9% between 2090s. In the IRG suitability comparison classes between domestic and introduced cultivars, the ratio of suitable and best suitable areas was relatively high in the domestic varieties during the past 30 years. However, there is almost no difference between the IRG domestic and introduced varieties in the IRG suitability classes after the 2050s. These results can predict changes in the IRG suitability classes between domestic and introduced cultivars according to the climate change scenario, but there are limitations in accurately predicting the productivity of IRG because the results may vary depending on other environmental factors.

Phytoplanktons were collected from various environments including small marshes, small ponds, reservoirs and brackish water from March 2017 to November 2017. In this study, five species of family Scenedesmaceae were newly recorded in Korea. The genus Desmodesmus was newly reported in Korea. The newly recorded species are Scenedesmus nanus, S. praetervisus, Desmodesmus costato-granulatus, D. lunatus and D. spinulatus. S. nanus and S. praetervisus are known to occur in freshwater, but they were found in the brackish water in this study.

Hyperacture rejection (HAR) of pig organs, upon xenotransplantation into primates, could partly be overcome by knocking out the alpha-Gal gene. However, xenotransplanted organs may still undergo immunological acture rejection (AR) or acute vascular rejection (AVR). Among several genes involved in AR and AVR, the hCD47 evades the monocyte/ macrophage mediated phagocytosis by identifying the self/non-self signal (CD47-SIRPa) whereas hTFPI participates in the regulation of coagulation pathway by acting upstream of the thrombin. In this study, we investigated hCD47 and hTFPI as two possible candidates for avoiding AR and AVR, respectively upon pig-to-human xenotransplantation. A co-expression vector for hCD47 and hTFPI was constructed using 2A peptides system (F2A) and transfected into the porcine kidney cell line (PK-15). The transfected cells stably expressed both hCD47 and hTFPI mRNA and proteins. Co-culture of non-transfected, hCD47-transfected, hTFPI-transfected or hCD47+hTPFI-transfected PK15 cells with natural killer (NK) cells, monocytes and macrophages confirmed the cytotoxic effect of hCD47 and revealed a synergistic effect of hCD47 and hTFPI co-transfection. There was an attractive survivability of 25～30% on each type of innate immune cell, NK cell and macrophage. These results suggest that transgenic pigs, genetically modified for hCD47 and hTFPI may be useful for overcoming xenograft rejection. Furthermore, cotransfection with hTFPI may enhance the cytotoxic effect of hCD47, possibly by assisting the hCD47-SIRPa binding by an unknown mechanism.

Environment-friendly growth enhancers for rice are being promoted to reverse the negative impact of intensive chemical-based and conventional rice farming on yield sustainability and environmental problems. Several rhizosphere microorganisms and pyroligneous acids (PA) had demonstrated beneficial influence on growth, yield and grain quality of rice. Since most of the previous study had evaluated the effect of PGPR and PA on paddy rice singly, the effect of combined application of these on the growth and yield of paddy rice and on some soil chemical properties were determined. A four factorial pot experiment was conducted to evaluate the effect of PGPR, PA in combination with fertilizers and on different soil types. There were 54 treatment combinations including the control with three replications under complete randomized design. Plant growth parameters were evaluated using standard procedures during tillering and heading stages. Rice yield and some soil chemical properties were determined at harvest. Results showed that inoculation of Bacillus licheniformis and Fusarium fujikuroi enhanced plant growth by increasing the plant height which could be ascribe to its ability to promote IAA and GA production in plants. Inoculation of Rhizobium phaseoli enhanced chlorophyll content indicative to its ability to improve the N nutrition. However, these plant growth benefits during the vegetative stage were override by the fertilizer application effect especially during the maturity stage and grain yield. High fertilization rates on coarse-textured soil without nutrient loss resulted to high available nutrients and consequently high yield. Wood vinegar application however improved nutrient availability in soil which could be beneficial for improving soil quality. Further evaluation is necessary to fully assess the potential benefits that could be derived from inoculation of these organisms and wood vinegar application in different soil environment especially under different field conditions.

Concentrations of PCBs in the sediment of the Kumho River was determined. Samples were collected at 23 locations along the river. Total PCB levels ranged from 2.7 to 87.6 ng/g dry weight. The site near the Keomdan factory district had the highest concentrations. The levels of PCB congeners significantly correlated with the total organic carbons in the sediment. The major fractions of PCBs were congeners containing 4, 5, or 6 chlorine atoms per biphenyl molecule.
