최선영(Choi, Sun-young) 문학과환경학회 2015 문학과 환경 Vol.14 No.3

Novel named “Trees standing on the slope” was written by novelist Hwang Sun-won after the 1960s that belonged to latter half period of Hwang"s novel works. Before the 1960s, Hwang"s novel works described fragments of human world that expressed not only conciliation but also warm humanity, while after the 1960s, his works reflected realities of the society to investigate the society deeply. However, evaluation and rhetoric of his works came from his works at initial times. However, the novel works made change at quality level to a certain degree considering geopolitical factors more than Hwang Sun-won"s works in previous times did. Novel of “Trees standing on the slope” that belonged to novel of latter half period of Hwang Sun-won had different characters and symbols than those of other novels of Hwang had. This study criticized analysis upon characters focused on humanism to find out values from various kinds of points and to interpret Hwang"s point of view of the world at “Trees standing on the slope”. Sukee"s path could be interpreted to be motherhood of reconciliation and embracement from point of view of humanism that Hwang Sun-won adhered to. Such a thought could be criticism in the 1950s that was abstract and absolute humanism. And, mythified violence of motherhood was thought to be reinforced. In this study, ‘pruning’ of Chapter II interpreted value of dualism to investigate Sukee and her pregnancy from point of view of not common value but multiple values. Men could get new fruit after pruning of trees or could not. Suggestion of possibility of fruit was not thought to give optimistic prospect. On the contrary, focus on pruning was likely to finish end. Of course, the novelist gave an alternative for not only destruction but also construction in his novel work that could not be practical way of before and after realities. Value of individuals could not be judged from point of view of humanism behavior to overcome cruelty of war experience and to recover humanism. The ideology of humanism for affirmative and optimistic future of pains of post-war generation in the history was rather abstract and ideological. Hwang Sun-won deeply investigated by symbols and characters. For instance, an woman named Sukee was thought to be new character who overcame the limitation to be made by the novelist. The study investigated the work carefully to have viewpoint of current times. Study on Hwang Sun-won"s novel was not rescue of completed world but cognition on new realities with possibility of incompleteness to create characters and to interpret in various ways.

Modeling of CO₂ Emission from Soil in Greenhouse

Lee, Dong-Hoon,Lee, Kyou-Seung,Choi, Chang-Hyun,Cho, Yong-Jin,Choi, Jong-Myoung,Chung, Sun-Ok Korean Society of Horticultural Science 2012 원예과학기술지 Vol.30 No.3

Greenhouse industry has been growing in many countries due to both the advantage of stable year-round crop production and increased demand for fresh vegetables. In greenhouse cultivation, $CO_2$ concentration plays an essential role in the photosynthesis process of crops. Continuous and accurate monitoring of $CO_2$ level in the greenhouse would improve profitability and reduce environmental impact, through optimum control of greenhouse $CO_2$ enrichment and efficient crop production, as compared with the conventional management practices without monitoring and control of $CO_2$ level. In this study, a mathematical model was developed to estimate the $CO_2$ emission from soil as affected by environmental factors in greenhouses. Among various model types evaluated, a linear regression model provided the best coefficient of determination. Selected predictor variables were solar radiation and relative humidity and exponential transformation of both. As a response variable in the model, the difference between $CO_2$ concentrations at the soil surface and 5-cm depth showed are latively strong relationship with the predictor variables. Segmented regression analysis showed that better models were obtained when the entire daily dataset was divided into segments of shorter time ranges, and best models were obtained for segmented data where more variability in solar radiation and humidity were present (i.e., after sun-rise, before sun-set) than other segments. To consider time delay in the response of $CO_2$ concentration, concept of time lag was implemented in the regression analysis. As a result, there was an improvement in the performance of the models as the coefficients of determination were 0.93 and 0.87 with segmented time frames for sun-rise and sun-set periods, respectively. Validation tests of the models to predict $CO_2$ emission from soil showed that the developed empirical model would be applicable to real-time monitoring and diagnosis of significant factors for $CO_2$ enrichment in a soil-based greenhouse.

Choi,Seong-Kyu,Yun,Kyeong-Won,Kwon,Byung-Sun 한국자원식물학회 2002 Plant Resources Vol.5 No.2

To develop optimal storage method of root of Peucedani Radix, which has been grown as major cultural herbal medicine material, root of Peucedani Radix was stored for 10 months with different packing materials and sealing methods. The loss in dry weight as influenced by packing materials and sealing methods was the lowest at vacuum packing and followed by complete sealing methods with transparent polyethylene film. The ratio of root rot during the storage period was not significantly different between packing materials but was significantly different between sealing conditions. Conclusively vacuum packing and complete sealing with polyethylene film appears to be optimal for storage of Peucedani Radix.

Case Report : A Case of Epstein-Barr Virus-associated Hydroa Vacciniforme

Sun Young Huh,Mira Choi,Kwang Hyun Cho 대한피부과학회 2009 Annals of Dermatology Vol.21 No.2

Hydroa vacciniforme (HV) is a photosensitivity disorder characterized by recurrent necrotic vesiculopapules on sun-exposed areas, which heal spontaneously during adolescence. Recently, an association has been reported between latent Epstein-Barr virus (EBV) infection and atypical HV-like eruption and malignant potential. However, latent EBV infection has also been reported in the setting of typical HV. An 11-year-old girl presented with recurrent, scattered, discrete vesicular eruptions with scarring on the face and the extensor surfaces of both forearms. In-situ hybridization was carried out to detect latent EBV infection. Based on the clinical and histopathological findings, typical EBV-associated HV was suspected.

Development of a Reduction Algorithm of GEO Satellite Optical Observation Data for Optical Wide Field Patrol (OWL)

Sun-youp Park,Jin Choi1,Jung Hyun Jo,Ju Young Son,Yung-Sik Park,Hong-Suh Yim,Hong-Suh Yim,Hong-Kyu Moon,Young-Ho Bae,Jang-Hyun Park 한국우주과학회 2015 Journal of Astronomy and Space Sciences Vol.32 No.3

An algorithm to automatically extract coordinate and time information from optical observation data of geostationary orbit satellites (GEO satellites) or geosynchronous orbit satellites (GOS satellites) is developed. The optical wide-field patrol system is capable of automatic observation using a pre-arranged schedule. Therefore, if this type of automatic analysis algorithm is available, daily unmanned monitoring of GEO satellites can be possible. For data acquisition for development, the COMS1 satellite was observed with 1-s exposure time and 1-m interval. The images were grouped and processed in terms of “action”, and each action was composed of six or nine successive images. First, a reference image with the best quality in one action was selected. Next, the rest of the images in the action were geometrically transformed to fit in the horizontal coordinate system (expressed in azimuthal angle and elevation) of the reference image. Then, these images were median-combined to retain only the possible non-moving GEO candidates. By reverting the coordinate transformation of the positions of these GEO satellite candidates, the final coordinates could be calculated.

Activate charcoal (AC) can be utilized as a soil conditioner in agricultural crop areas. This study was conducted to investigate the effect of AC on growth and yield of Zingiber mioga ROSC as affected by different amounts of AC. The results obtained are summarized as follows. Growth characteristics including plant height and leaf length were the highest when activated charcoal added with 10-30%, suggesting that optimum amount of activated charcoal was ranged from 10 to 30%. Growth and enlargement of the root were improved by 10% AC with higher rhizome length and weight.
