  • The ESBs (Environmental Specimen Banks) have monitoring functions for the contemporary environmental qualities and also offer the future generation tangible information on the past environment by preserving the specimens. This entails the sampling of the representative specimen for each distinctive ecosystem, which is performed under a strict and stipulated procedure and a condition that does not allow any change in the component so that a retrospective analysis can be readily done even in the distant future. It has been more than 30 years that some developing countries started collecting a broad spectrum of specimens to vindicate the effectiveness of an environmental policy and to monitor the long-term variations of background concentrations of environmental pollutants. Though being late, the National Institute of Environmental Research (NIER), Korea, has successfully launched the National Environmental Specimen Bank (NESB) in 2009 equipped with its state-of-the-art automated cryogenic tanks. Since then, the researchers at the NESB have been doing their best to excel the existing ESBs around the world by learning and improving the expertise. To do so, they conducted a pilot study for developing and testing their own Standard Operating Procedure (SOP) based on the analysis of the examples of the other ESBs. The problems from the pilot study had been reviewed to improve the SOP to meet the requirements for an ESB, that is to say, preserving representative environmental specimens in cryogenic condition and enhancing the analytical method. Furthermore, they also need to prepare themselves to address the future challenges by providing some additional functions, which makes it distinguishable from the other ESBs. If successful, this will be a step further to be recognized as a full-fledged member of the ESB society of the world.

  • The present study was retrospectively designed to define whether preoperative levels of leukocytes and D-dimer are potentially useful factors in predicting perioperative outcomes of coronary heart disease (CHD). There was no relationship between preoperative leukocyte counts (Pre-OP leukocyte) and preoperative D-dimer levels (Pre-OP D-dimer). Pre-OP leukocyte counts each had positive correlation with cardiac troponin-I, creatine kinase-MB or C-reactive protein (cardiac markers) levels at preoperative and postoperative periods. Pre-OP D-dimer levels were positively associated with each cardiac marker at the same periods. Pre-OP leukocyte counts positively related with aspartate aminotransferase and alanine aminotransferase (liver markers), whereas Pre-OP D-dimer level positively or negatively correlated with bilirubin (liver marker), creatinine (renal marker) or glucose levels at preoperative and/or postoperative periods. Pre-OP leukocyte and Pre-OP D-dimer were inversely associated with Pre-OP high density lipoprotein cholesterol levels or left ventricular ejection fraction. Pre-OP leukocyte counts each had positive correlation operation duration and postoperative mechanical ventilation-time (PMVT), whereas Pre-OP D-dimer levels had positive relationship with PMVT, intensive care unit-staying period and hospitalization. The retrospective data suggest that Pre-OP leukocyte and Pre-OP D-dimer levels may be clinically useful factors for predicting perioperative outcomes in patients with CHD.

  • In this essay, I examine the interactions of chronotopes in the narrative of Gangnam Blues, a film written and directed by Yu Ha and released in 2015. Bakhtin's chronotope, the connectedness of temporal and spatial relationships in literary narratives, provides the background for the representability of events and becomes the organizing center for the events. Each chronotope offers a different way of acting, interacting and understanding experience, and chronotopes can interact with each other in a single text or between the reader and the represented world. Gangnam Blues is a gangster movie, first of all, showing an individual's illusion of an unlimited possibility for achieving wealth and power. At the same time, the film describes the government's project to transform Gangam, a rural area in the south of the Han, into a new downtown and residential area for Seoul. As the world in the narrative and the world of the author or the reader are all chronotopic, we can see the interactions of chronotopes between the narrative of an individual and the historical narrative, as well as between the narrative about the beginning of Gangnam and the audience's perception of the present Gangnam. In this film, the main character's ambition is shown as part of the social desire for rapid economic achievements in the 1970s, along with high social mobility. The social desire can be explained as envy, as it is fueled by social comparisons and competitions. The main character's pursuit of money and power through the possession of Gangnam land overlaps with the envious desire for the present Gangnam shared by many. The individual's exceptional ambition and violence are not fully examined in this text. Moreover, the film's dependence on the feelings of envy to represent the individual's choice and violence can be a symptom of the lack of critical distance from social desire and envy.

  • Sinheung Military Academy was the first one which prepared for independence war built by members of Sinminhoe in Western Manchuria. Sinheung Military Academy is known that nurtured 3,500 independence soldiers during 10 years from 1911 thorough 1920. Nevertheless no people know how it recruited so many students for 10 tears. In the course of studying the recruit of Sinheung Military Academy, I became to focus on Manjugisa by Yi Sang-nyog. Although Yi Sang-nyon remembered that there were over five hundred students in Sinheung Military Academy from just after it's set up in Manjugisa, scholars overlooked that mention so far. In addition, in the Sixth poem of Manjugisa, Yi Sang-nyong recollected that there were 30 preliminary educational organizations in 1918 after installation of Sinheung Military Academy in 1911. Therefore I concluded that the over 500 students nurtured from just after installation of Sinheung Military Academy were summed up students of preliminary educational organizations over Sinheung Military Academy's and proved it. The students of preliminary educational organizations in Liuhexian Tonghuaxian entranced into Sinheung Military Academy after graduation. The graduates of Sinheung Military Academy taught the students of preliminary educational organizations a common and military educations in duty for two years. In conclusion, Sinheung Military Academy and nearby preliminary educational organizations were an wide military camp organically maintained by Korean in Western Manchuria for big purpose of independence war.

  • This study was to conceptualize Palzha and investigate Palzha inference as mode of self-view. In general, people would like to attribute their unhappy and unfortunate life events or histories to Palzha which is given by the supernatural being. According to analysis of interviews and open-ended responses concerning on Plazha, Palzha indicated 'luck', 'uncontrollable situation', or 'fate' given by the supernatural being. In study 2, we conducted an analysis of the relationship between locus of control belief and Palzha attribution. More having external control belief, more tending to attributing the rugged life events or histories, and unexpected fortunate events to Palzha. Consequently, Palzha as mode of self-view on everyday events or life-events indicated it is likely to be another dimension of attribution on negative as well as positive life events in Korean culture.

  • The development of Korean urban geography can be divided into several stages including initial stage, transition stage, and maturation stage. If this trend persists, it can be expected that it would turn into the matured stage. This paper intended to recall the research trends from 1960 to 2012, focusing on 686 papers and 177 books published during the last 62 years, and investigated by research areas, study regions, methodologies, and journals in relation to urban geography. Although increasing number of urban geographers has made mutual relationship more complex and diverse, no signs of school formation have yet been seen in Korean urban geography. Large portions of papers have concerned about Seoul Metropolitan Region for their study regions. There have been diversified trends of oversea studies away from the US cities to other cities in various countries. Also, quantitative studies have been increasing their weight since the 2000s. Moreover, articles on the Journal of the Korean Urban Geographical Society have been far surpassed in its number.

  • The purposes of the present study were to investigate the effects of individual, family, and school factors on the onset of adolescents' violence behaviors. For these goals, we applied discrete-time survival analysis to the Korean Youth Panel Survey. According to the estimated hazard function, the likelihood of onset of adolescents' violence behavior was low during elementary school years and increasing sharply from middle school years. Results showed that gender, self-esteem, aggressiveness, broken home, parental abuse, and the number of delinquent friends were significant determinants of the onset of adolescents' violence behaviors. Findings from this study suggest the need to focus on the significant determinants and consider various prevention programs.
