Postcolonialism, as a school of thought, has become enormously influential for understanding the recent phenomena of globalization. While rejecting the universalizing categories of the Enlightenment, postcolonialism has called into question the old idea of culture and identity as a transcendent regime of authenticity and purity. It has also celebrated the diasporic experiences that entail porous and hybrid cultural identities as a potential site of struggle and resistance against the dominant cultural and discursive order. It is argued, however, that postcolonial theory's emancipatory claims relating to the diversified global culture tend to be complicit with transnational capitalism that brings about global issues of material as well as cultural injustice. This article, through a thorough review of the ways the postcolonial theoretical framework has been developed and appropriated by main figures in postcolonial scholarship, seeks for a theoretical and critical strategy to grasp the complex conditions of global inequality.

The hospital wastewaters have to be so disposed as to prevent disease and to protect water resources from hazardous substances disinfectants, medicines, and chemicals. Polyvinylpyrrolidone-iodine complex (povidone-iodine) is widely used in the hospital as one of disinfectants. This study was carried out to manifest the effect of disinfectants in growth of activated sludge in treatment of the hospital wastewater by the activated sludge process. The results are as follow. 1. An average water quality of the hospital wastewater showed 7.2 in pH, 3.2 ppm in DO, 293.3 ppm in SS, 96.0 ppm in BOD, 151.1 ppm in COD, 0.4 ppm in povidone-iodine, 0.5 ppm in phenols, 5.4 ppm in surfactants, 1.6 ppm in o-phosphate, 4.6 ppm in $NH_3-N, 249\times 10^4$ counts/100 ml in coliform group organisms, and $1,369\times 10^2$ counts/ml in general counts of bacteria. And wastewater amounts discharged per bed was calculated 70 l/d/bed. 2. In batch culture activated sludge process, each of cresol and povidone-iodine was not effected in less than 0.1 ppm concentration, but the more concentration, the more inhibit the growth rate of activated sludge. In the mixture of two disinfectants, the growth was more inhibited the effect of single disinfectants. So that this reaction is considered as addition effect of two disinfectants. 3. The removal rates of the disinfectants-by continuous culture activated sludge process were 77.6% in 0.4 ppm povidone-iodine, and in BOD was 85.6%. 4. It is desirable that the hospital wastewater is planed in order to be discharged to two system separately, sewer from life system and wastewater from medical system. From those results, it has been concluded that the hospital wastewater has to be treated safely by the activated sludge process.

The purpose of this study is to consider the design characteristics of Chinese traditional clothing, especially from the Ming-Qing Dynasty era, and how they have influenced contemporary fashion. Regarding research methods, this study determined the design characteristics, such as the form, color and pattern of Chinese traditional clothing of the Ming-Qing Dynasty era. In addition, 440 photos were collected from the Paris Collection from 2005 to 2014 using www.firstviewkorea.com. The results of this study are as follows. First, the most popular silhouette from Chinese traditional clothing appearing in contemporary fashion was the H-shaped one, and the internal lines appeared in the following order: Chinese collar; narrow sleeve; symmetrical front opening; round collar; wide sleeve; and the C-shaped Biwa front-end. Second, the most popular color was achromatic black, followed by white. The chromatic colors were in the order of blue, yellow, red, green, and purple. Third, the patterns appeared in the following order: Plant patterns, complex patterns, and animal patterns. The peony pattern appeared the most commonly as a plant pattern, followed by the arabesque pattern and the plum blossom pattern which appeared with a similar proportion. Dragon, bird and phoenix patterns appeared the most for animal patterns. It is considered that the results of this study will be helpful for designing products for Korean fashion brands that will advance to the Chinese market. In addition, it will help Chinese designers apply the Chinese-style design characteristics popular among people throughout the world when they advance to the West.

The warfare caused a dramatic change when new technology was introduced to the battlefield or when the technology was matured to change the concept of operation. Thus, the rapid development of science since the 19th century is also rapidly changing the aspect and speed of war, and the recent speed of change is making it more difficult to predict future warfare than in the past In particular, in the past, it was difficult to predict the future warfare based on the latest science and technology, because it was difficult to spread and seize advanced science and technology. But global human exchange, technology hijacking by internet, and developing of asymmetric skills and methods caused more complex to technology based warfare prediction. In other words, the nature and principles of war, together with the development of science and technology, should be considered togther to predict future warfare. Therefore this study is based on the thory and principles of war and the latest science and technology to predict the future warfare situation that the military will face.

Purple non-sulfur (PNS) bacterium $Rhodobacter$ $sphaeroides$ KD131 was studied with the aim of achieving maximum hydrogen production using various carbon and nitrogen sources at different pH conditions. Cells grew well and produced hydrogen using $(NH_4){_2}SO_4$ or glutamate as a nitrogen source in combination with a carbon substrate, succinate or malate. During 48h of photo-heterotrophic fermentation under 110$W/m^2$ illumination using a halogen lamp at $30^{\circ}C$, 67% of 30mM succinate added was degraded and the hydrogen yield was estimated as 3.29mol $H^2$/mol-succinate. However, less than 30% of formate was consumed and hydrogen was not produced due to a lack of genes coding for the formate-hydrogen lyase complex of strain KD131. Initial cell concentrations of more than 0.6g dry cell weight/L-culture broth were not favorable for hydrogen evolution by cell aggregation, thus leading to substrate and light unavailability. In a modified Sistrom's medium containing 30mM succinate with a carbon to nitrogen ratio of 12.85 (w/w), glutamate produced 1.40-fold more hydrogen compared to ammonium sulfate during the first 48h. However, ammonium sulfate was 1.78-fold more effective for extended cultivation of 96h. An initial pH range from 6.0 to 9.0 influenced cell growth and hydrogen production, and maintenance of pH 7.5 during photofermentation led to the increased hydrogen yield.

Purpose: The aim of this study was to evaluate the influence of the mothers' native country on influenza vaccinations in adolescents in multicultural families. Methods: Data were gathered from the 13th (2017) Youth Risk Behavior Web-Based Survey. Logistic regression analyses were conducted using a complex sample data analysis method. The participants in this study had a father who was born in Korea and a mother born outside of Korea. The sample included 481 adolescents. Results: The analysis of non-adjusted confounding variables showed that influenza vaccination was higher in multicultural adolescents whose mother's native country had an annual minimum temperature less than $21^{\circ}C$ (odds ratio [OR]: 1.81, 95% confidence interval [CI]: 1.20~2.74). Furthermore, when the analysis was adjusted for confounding variables, an annual minimum temperature less than $21^{\circ}C$ in the mother's native country had a statistically significant association with influenza vaccination (OR: 2.12, 95% CI: 1.36~3.29). Conclusion: Multicultural adolescents belong to a socioeconomically vulnerable class, and their health promotion behaviors are influenced by their mothers' culture. Thus, healthcare providers and school nurses should provide adolescents with appropriate information related to influenza vaccination depending on their mothers' culture and their family's cultural background.

The conclusions shown by this study are as follows: Firstly, Despite the similarity of the objective distance caused by the geographic distance and cultural similarities. it is found that the psychic distance factor still exists. Secondly, a new affective factor of psychic distance has been noted. As to the shaping method, even though culture and psychic distance involve homeogenic factors, psychic distance is more complex in that it is affected not only by cultural changes but also by other affective factors. Culture is a very significant factor, which can have an effect on forming psychic distance, but it is short of being a measurement variable for measuring psychic distance. Thirdly, psychic distance can have a direct effect on customers' buying response. If it is just a belief shared among the people of a nation, it can't become an important notion.

This research intended to conduct literary research on 'Jeok' of 25 jong-ga through Jong-ga Ancestral Ritual Formalities and Food, published by the Cultural Heritage National Research Institute of Cultural Heritage during 2003~2008, and compared and analyzed an arranging method and recipe transmission process by directly visiting four Jong-ga. Religious ceremony foods of Jong-ga could be divided according to the standard of the hakpa attribute (large), regional attribute (midium), and family attribute (small), which forms a complex connection structure between the attributes. 'Jeok' arranging form is divided into '3-Jeok building method (vertical structure)', '3-Jeok arrangement method (horizontal structure)', '3-Jeok replacement method', '2-Jeok arrangement method', 'Jeon-Jeok arrangement method', and 'Others-Jeok arrangement method'. Generally, 'jeok' arrangement order per hakpa is in the order of 'meat jeok - chicken jeok - fish jeok' in case of Gihohakpa, whereas Yeongnamhakpa is in the order of 'fish jeok - meat jeok - chicken jeok'. Umoringye (羽毛鱗介), the method of laying 'dojeok' of the Gyeongbuk region, could be found in the 2nd century B.C. Chinese ancient book Hoenamja and the theoretical background was Yin and yang philosophy (陰陽論). This research has significance in terms of securing advanced results compared to advanced research that has so far concentrated on some regions and hakpas.

This study was designed to investigate nutrition intakes and its relation to the obesity and the prevalence of anemia in 252 children(136 boys, 116 girls) aged $2{\sim}6$ years. The hematological parameters, daily nutrient intakes and height and weight were measured. Calorie intakes of 2 and 3year-old-children were over their RDA while those of 4-6 years were below the RDA. Intakes of protein, P, and vit B complex were far over the RDA in all ages of children. Fe and vit A intakes were insufficient in all ages except 3 years while Ca intakes were insufficient in all ages except 2 and 3 years. About 18.2% of the children were evaluated as obese. However, very few children were anemic by hematologic parameters. The mean Hb concentrations were 12.2mg/dl in boys and also in girls. The mean Hct was 36.2% in boys, 35.8% in girls. Serum Fe concentration was 100.1mg/dl in boys, 101.1mg/dl in girls. RBC count was significantly higher in boys while MCH was significantly higher in girls. Intakes of protein, P, Fe, vit $B_1$, niacin, vit C were significantly higher in obese group compared to under weight group. There were significant positive correlations between protein intake and Hb, Hct, MCH, and MCHC. The correlation between Fe intake and Hb or Hct was not significant. In conclusion, it seems that the nutritional status of the most children was in very good condition. However, they needed to take more foods supplying Fe, Ca, and vit A.
