In modern Chinese, 'Qu去' is mainly used as a verb in the meaning of 'go', and 'Wang往' is used as a preposition to indicate the direction of movement in the meaning of 'toward'. Historically, both 'Qu去' and 'Wang往' have been mainly used as moving verbs. We also pay attention to their common feature that they were used as noun, adjective and preposition, and the other feature that 'Qu去' and 'Lai来', 'Wang往' and 'Lai来' were used as typical antonyms each other. Based on the research results of the existing scholars, this study examined the part of speech, the meaning and usage in connection with the appearance of 'Qu去' and 'Wang往' in Tang-Song Dynasty. Chapter II examined usage of 'Qu去' and 'Wang往' prior to Tang-Song Dynasty, and Chapter III looked into the use of 'Qu去' and 'Wang往' in Tang-Song Dynasty by analyzing actual example sentences.

도시는 지속적으로 변화하고 있으나, 도시어항은 도시화에 비해 쇠퇴되고 있다. 도시어항 어민들의 어업활동은 축소되고 있으며, 어항의 새로운 변화와 활력이 필요한 실정이다. 그러나 어촌계의 고령화, 어항구역 및 인접 대지의 토지활용 등 실질적인 한계점은 어항의 발전을 저해하고 있으며, 본 연구에서는 이를 극복할 수 있는 대안으로서 암남항 해녀와 낚시 콘텐츠를 활용한 해양문화콘텐츠를 제시하고자 한다. 또한 2022년 암남항 어촌뉴딜300사업 시행에 앞서, 암남항의 해양문화콘텐츠를 개발하고 도시어항 공간환경마스터플랜을 수립함으로서 암남항의 새로운 발전을 도모할 수 있는 실질적인 연구 수행의 의의가 있다.

In this study, a GIS model to simulate the behavior of surface forest fires was developed on the basis of forest fire growth prediction algorithm. This model consists of three modules for data-handling, simulation and report writing. The data-handling module was designed to interpret such forest fire environment factors as terrain, fuel and weather and provide sets of data required in analyzing fire behavior. The simulation module simulates the fire and determines spread velocity, fire intensity and burnt area over time associated with terrain slope, wind, effective humidity and such fuel condition factors as fuel depth, fuel loading and moisture content for fire extinction. The module is equipped with the functions to infer the fuel condition factors from the information extracted from digital vegetation map sand the fuel moisture from the weather conditions including effective humidity, maximum temperature, precipitation and hourly irradiation. The report writer has the function to provide results of a series of analyses for fire prediction. A performance test of the model with the 2002 Chungyang forest fire showed the predictive accuracy of 61% in spread rate.

Today, because human settlements are concentrated into urban area, urban planning and management technique considering the complexity, diversity, and advanced situations of urban living space is being requested. Especially, to effectively respond to large and diverse climate change driven disaster, it is necessary to develop urban planning technique including land use, infrastructure planning based on disaster vulnerability analysis. However, because current urban climate change disaster vulnerability analysis system(UC-VAS) is using census output area as spatial analysis unit, it is difficult to utilize the analysis results for specific urban planning. Instead, this study applies the grid manner to two study areas. The analysis results show that it can generate more detailed results and it can be used for detailed zoning decision by comparing with areal photos. Furthermore, by describing the limitation of the grid manner and providing professional way to secure additional scientific character and objectivity of the future urban climate change disaster vulnerability analysis system, it is expected that this study contributes to the effectiveness of system management.

This study aims to solve the problem of class imbalance in numerical data by using a deep learning-based Variational AutoEncoder and to improve the performance of the learning model by augmenting the learning data. We propose 'D-VAE' to artificially increase the number of records for a given table data. The main features of the proposed technique go through discretization and feature selection in the preprocessing process to optimize the data. In the discretization process, K-means are applied and grouped, and then converted into one-hot vectors by one-hot encoding technique. Subsequently, for memory efficiency, sample data are generated with Variational AutoEncoder using only features that help predict with RFECV among feature selection techniques. To verify the performance of the proposed model, we demonstrate its validity by conducting experiments by data augmentation ratio.

Flumazenil is a competitive antagonist of benzodiazepines. It is usually administered intravenously. However, if the intravenous route is not available then other routes of drug administration should be considered. This study was designed to evaluate the reversal effects of flumazenil after nasal administration. Twenty-five young, healthy adult volunteers participated in this clinical trial. The dosage of 0.08mg/kg midazolam was administered intravenously to induce deep sedation. Ten minutes after midazolam administration, 0.5mg of flumazenil was dropped nasally, over a period of one minute. Blood samples were taken to measure the concentration of midazolam and flumazenil at 0, 5, 10, and 20min after nasal administration of flumazenil, using High Performance Liquid Chromatography. The degree of sedation was evaluated with sedation score and bispectral index (BIS), Statistical analysis was performed by multivariate ANOVA and correlation analysis (P<0.05). Peak serum flumazenil concentration was reached in 10min. Sedation score decreased after midazolam administration and showed a significant increase after flumazenil administration. However, BIS decreased during the first 10min after midazolam administration and then no significant changes after flumazenil administration. There were two instances representing rapid and complete reversal of midazolam after intranasal administration of flumazenil. In conclusion, intranasal flumazenil administration may be effective in some patients when intravenous route is not available in condition of benzodiazepine overdose.

일반적으로 소규모 댐은 용수전용 댐으로 홍수조절능력이 없고, 대규모 댐 관리와 같은 운영 기준이 정립되어 있지 않은 현실이다. 따라서 최근 이상기후에 대해 가뭄과 홍수피해가 빈번히 발생하고 있으며 정주권의 변화와 농촌용수의 다양화로 피해 규모도 증가하고 있다. 따라서 본 연구에서는 소규모 댐 중 가장 많은 비중을 차지하는 관개용 댐을 대상으로 유역의 용수수급 현황을 분석한 후 저수위의 효율적 운영이 가능하도록 일년을 4개의 기간으로 결정하여 기간별 관리수위와 운영기법을 연구 하였다. 소규모 댐은 대부분 방류능력이 부족하여 예비방류의 적용이 불가능하다. 따라서 기간별 관리수위를 사용하여 홍수조절 공간을 사전에 확보하고, 무효 방류량을 최소화 하고자 하였다. 각 관리기간은 관개기와 홍수기를 기준으로 구분되며 최소유출량 계열과 용수수요량의 빈도분석을 통해 용수확보에 문제가 없으며, 홍수기 대비가 가능한 관리수위로 결정하였다. 관리수위를 기준으로 운영한 결과 실제 관리보다 추가 사용 가능량이 발생하였고, 저수공간의 폭이 넓었다. 따라서 넓은 저수공간의 활용으로 홍수조절능력을 향상시켜 제한수위의 적용이 가능하였다. 홍수영향 분석을 실시하고 제한수위 따른 수문조작 기법을 적용한 결과 홍수조절능력이 향상되는 것으로 나타났다.

In this study, We compared the properties of tinted and colored lenses with the standards m the ordinary optical properties, coloration, UV, IR and luminous transmittance, color acceptance for traffic signal, and chromaticity. The UV, lR and luminous transmittance was analysed in the range of 175 nm to 3000 nm by using a UV-Vis-IR spectrophotometer and was used in the synthesis of spectrum of various color lens. A experimental function was made from the slope obtained from the transmittance change as a function of coloration time. We could expect the ordinary optical properties and color acceptance for traffic signal of various color lenses with the requirements of US standard(ANSI Z-80.3).

The cultural production of meanings is becoming more and laden with the intricacies of signs and symbols in our times. The idea of 'character' is important as an intermediation for information and an essential characteristic of "the object" experienced through the sence of sight. Character is symbolicin its form but also in its iconic markings. Motion Picture Animation makes Character not just an expression of an image but visual communication that expands the action of meaning piled up, sign upon sign. The analysis of 'character' suggests that motion picture animated characters could play an important role as a cultural mode leading to new styles not merely as an aesthetic mechanism. The study there with analyzed animated character systematically to discem where the sign phenomena shows up in social conventions under the semiotic rigor of Peirce's concepts of icon, index, and symbol.
