Culture as a source of identity, as Edward Said says, can be a battleground on which various political and ideological causes engage one another. It is not mere individual cultivation or private possession, but a program for social cohesion. Sensitively aware that a national culture should be independent from Europe, Walt Whitman enacts a new form of literature by placing different cultural values against Old World tradition. His interest in autochthonous culture originates from his deep concern about national consciousness. He believes that literary taste directed toward highly-ornamented elite culture is an obstacle to cultural unification of a nation. In order to represent American culture of the common people, Whitman incorporates a lot of cultural material into his poetry. Since he believes that America has many respectable writers at home, he urges people to adjust to their own taste instead of running after foreign authors. Whitman differentiated his poetry from previous literary models by disrupting the established literary norms and reconfiguring cultural values on the basis of American ways of life. In his comment on other poets, he concentrates on the originality and nativity of poetry. By claiming that words have characteristics of nativity, independence, and individuality, he envisions American literature to be distinguished from British literature in literary materials as well as in language. Whitman s language is composed of a vast number of words that can fully portray the nation. He works over language materials in two ways: reterritorialization and deterritorialization. Not only does his literary language become subversive of the established literary language, but also makes it possible to express strength and intensity in feeling.

Currently, the rewards programs offered by many companies to strengthen customer relationships have been working quite well. In addition, many companies' rewards programs, designed for stabilizing revenue, are recognized to be effective. However, these rewards programs are not significantly differentiated between companies and there are no accurate conclusions currently, which can be made about their effects. Because of this, a company with a customer rewards program may not comprehend the true level of active participation. In this environment some companies' rewards programs inadvertently hinder business profitability as a side effect while attempting to increase customer loyalty. In fact, airline and oil companies pass on the financial cost of their programs to the customer, and as a result, they have been criticized publicly. The result of this is that the corporations with bad rewards programs tend to get a bad image. In this study of stores' rewards programs, we centered our focus on the design of the program. The main problem in this study is to recognize the financial value of the rewards program and whether it can create a competitive edge for the companies despite the cost issues experienced by them. Customers receiving financial rewards for their business may be just as satisfied with a particular company or store versus those who are not, and the program, perhaps, does not form a distinctive competitive advantage. When the customer is deciding between competing companies to secure their product needs with, we wanted to figure out how much of an affect a valuable reward program had on their decision making. To evaluate this, we set the first hypothesis as, "based on the level of involvement of the customers, there is a difference between customers' preferences for rewards programs." In the results of Experiment 1 we saw that in a financial compensation program for high-involvement groups and low-involvement groups, significant differences appeared and Hypothesis 1 was partially supported. As for the second hypothesis that "customers will have different preferences between a financial rewards programs (SE) and a joint rewards programs (JE)," the analysis showed that the preference for JE was significantly higher than that for other programs. In addition, through Experiment 2, we were able to find meaningful results, which revealed that consumers have shown a significant difference in their preferences between SE and JE. The purpose of these experiments was to enable the designing of a rewards program by learning how to enhance service information distribution and strengthen customer relationships. From the results, there should be a great amount of value for future service-related endeavors and academic research programs. The research is significant, because the results can be found to have a positive effect on reward program designs however, it does have the following limitations. First, this study was performed using an experiment, and all experiments have limitations. Second, although there was an individual evaluation and a joint evaluation, setting a proper evaluation criteria was difficult. In this study, 1,000 Korean won (KRW) in the individual evaluation had a value of 2 points, and, in the joint evaluation, 1,000 KRW had a value of 1 point. There may have been alternative ways to differentiate the evaluations to obtain the proper results. In this study, since there was no funding, the experiments were performed orally however, this was complementary to the study. Third, the subjects who participated in this experiment were students. Conducting this study through experimentation was unavoidable for us, and future research should be conducted using an actual program with the target customers.

Human umbilical cord blood(HUCB) contains a rich source of hematopoietic stem cells, mesenchymal stem cells and endothelial cell precursors. Mesenchymal stem cells(MSCs) in HUCB are multipotent stem cells, differ from hematopoietic stem cells and can be differentiated into neural cells. We studied on transdifferentiation-promoting conditions in neural cells and cholinergic neuron induction of HUCB-derived MSCs. Neural differentiation was induced by addingdimethyl sulphoxide(DMSO) and butylated hydroxyanisole(BHA) in Dulbeco's Modified Essential Medium(DMEM) and fetal bovine serum(FBS). Differentiation of MSCs to cholinergic neurons was induced by combined treatment with basic fibroblast growth factor(bFGF), retinoic acid(RA) and sonic hedgehog(Shh). MSCs treated with DMSO and BHA rapidly assumed the morphology of multipolar neurons. Both immunocytochemistry and RT-PCR analysis indicated that the expression of a number of neural markers including $\beta$-tubulin III, GFAP and MBP, was markedly elevated during this acute differentiation. The differentiation rate was about $32.3{\pm}2.9%$ for $\beta$-tubulin III-positive cells, $11.0{\pm}0.9%$ for GFAP, and $9.4{\pm}1.0%$ for Gal-C. HUCB-MSCs treated combinatorially with bFGF, RA and Shh were differentiated into cholinergic neurons. After cholinergic neuronal differentiation, the $\beta$-tubulin III-positive cell population of total cells was $31.3{\pm}3.2%$ and of differentiated neuronal population, $70.0{\pm}7.8%$ was ChAT-positive showing 3 folds higher in cholinergic population than neural induction. Conclusively, HUCB-derived MSCs can be differentiated into neural and cholinergic neurons and these findings suggest that HUCB are alternative cell source of treatment for neurodegenerative diseases such as Alzheimer's disease.

As the market of educational pet insects is expanding, understanding the consumer needs became more crucial. To achieve the ideal analysis on the market, this research monitored the behavior of consumers. The posting on the blogs of consumers, who have visited insect museums and farms, or have bought insects were collected as data. Moreover, the informational contents, photographs and texts, were analyzed. The results showed that the family-unit visitors with elementary school lower graders were the main type of visitors for their children's education. The visiting areas were concentrated in Seoul and the Metropolitans of Gyeonggi province, and the visits were mostly occurred during their children's vacation period. The analysis of posted photographs showed the visitors' high interest in the hands-on program. According to the texts on visitors' blogs, especially, the largest number of visitors satisfied with the variety of program. It implies the necessity of development in diverse and differentiated hands-on program. Otherwise, the programs available to connect insects to other animals and plants should be introduced to reduce aversion against insects, which was reported as the strongest dissatisfaction. In conclusion, diversification on insect species and development in systematized hands-on program seem to be required for the continuous growth of educational pet insects market.

The purpose of this study was to explore the direction of application and quality management plan of science curriculum of elementary and middle school according to the 2009 revised curriculum. In order to do this, nationwide survey was administered. The subject was 126 elementary school teachers and 88 middle school science teachers. It was founded that teachers had negative opinion on the introduction of the grade cluster system. They considered that it was appropriate to link the contents of Science subject with Practical Arts(Technology Home Economics) subject by similar topic. Science classes were implemented without changing the number of class hours in most schools. They recognized the necessity of differentiated instruction in science classes, but they seldom applied the differentiated instruction. And they suggested that the teaching-learning materials, evaluation materials and contents be provided to apply the STEAM. This study designates the following strategic supports for the effective implementation of 2009 revised science curriculum; 1) the science teachers training program to provide useful information for understanding and teaching the 2009 revised science curriculum, 2) the teachers' community in the school, 3) the development and provision of the feasible STEAM plans.

The purpose of the study is to investigate the convergence comparison of the stress, major satisfaction, career identity, and college adjustment of nursing students according to college admission process and grade. The 349 subjects were studying in the nursing department in the City P. And the data collection was carried out from April 2016 until May 2016. The data analysis was carried out with the frequency, the percentage, the ${\chi}^2$-test, and the ANOVA by using the SPSS 23.0 Program. Regarding the research results, first, there were no significant differences among the entire academic years according to the admission type. Second, regarding all the admission types according to the academic year, there were the significant differences among stress (p=.001), the degree of satisfaction with the major (p<.001), the sense of career path identity (p=.021), and the adaptation to the college life (p<.001). As a result, I propose that, based on these results of the research, as a strategy for reducing the stress and for improving the degree of satisfaction with the major, the sense of career path identity, and the capability to adapt to the college life on the part of the nursing students, a differentiated, customized educational program by type of admission and by academic year should be developed and applied.

Background: Delayed hypersensitivity plays a large role in the pathogenesis of tuberculous pleural effusion (TPE). Macrophages infected with live Mycobacterium tuberculosis (MTB) increase the levels of adenosine deaminase2 (ADA2) in the pleural fluid of TPE patients. However, it is as yet unclear whether ADA2 can be produced by macrophages when challenged with MTB antigens alone. This study therefore evaluated the levels of ADA2 mRNA expression, using monocyte-derived macrophages (MDMs) stimulated with MTB antigens. Methods: Purified monocytes from the peripheral blood mononuclear cells of healthy volunteers were differentiated into macrophages using granulocyte-macrophage colony-stimulating factor (GM-CSF) or macrophage colony-stimulating factor (M-CSF). The MDMs were stimulated with early secretory antigenic target protein 6 (ESAT6) and culture filtrate protein 10 (CFP10). The mRNA expression levels for the cat eye syndrome chromosome region, candidate 1 (CECR1) gene encoding ADA2 were then measured. Results: CECR1 mRNA expression levels were significantly higher in MDMs stimulated with ESAT6 and CFP10, than in the unstimulated MDMs. When stimulated with ESAT6, M-CSF-treated MDMs showed more pronounced CECR1 mRNA expression than GM-CSF-treated MDMs. Interferon-${\gamma}$ decreased the ESAT6- and CFP10-induced CECR1 mRNA expression in MDMs. CECR1 mRNA expression levels were positively correlated with mRNA expression of tumor necrosis factor ${\alpha}$ and interleukin 10, respectively. Conclusion: ADA2 mRNA expression increased when MDMs were stimulated with MTB antigens alone. This partly indicates that pleural fluid ADA levels could increase in patients with culture-negative TPE. Our results may be helpful in improving the understanding of TPE pathogenesis.

Morphological changes on digestive tract were observed using Flounder, Paralichthys olivaceus to elucidate the early developmental processes. Hatched larvae, ($2.50{\pm}0.14\;mm$ in total length: TL) has not opened its mouth and anus. The digestive tract showed linear tubular form from mouth to anus extending along with yolk. On $7{\sim}8$ days from hatching, the post-larvae, ($5.05{\pm}0.40\;mm$ TL) has developed digestive tract and activated for feeding. The digestive tract expanded into dorsal side, joined to intestine, and the stomach began to develop. The digestive tract was divided into an anterior and posterior region, and began to differentiate. In the post-larvae($6.50{\pm}0.25\;mm$ TL) on $13{\sim}14$ days from hatching, the digestive tract twisted one cycle in the anterior region, the area was expanded. The digestive tract was completely differentiated into oesophagus, anterior intestine, middle intestine, posterior intestine and arranges fundamental structure. In the embryo($12.40{\pm}0.55\;mm$ TL) after 30 days from hatching, stomach became large and could be distinguished from cardia and pyloric parts apparently. The digestive tract developed similar with that of adult flounder showing clear division of stomach, anterior intestine, middle intestine, posterior intestine and rectum. In the embryo($16.15{\pm}0.85\;mm$ TL) after 40 days from hatching, esophagus, pyloric part, anterior intestine, middle intestine, and rectum have largely expanded, and thus the morphological features are somewhot different with those of post-larvae flounder.

This study investigated the relationship among pain, depression and activities of daily living in nursing home residents. Data was collected through a structured questionnaire survey of residents at 4 nursing homes in S city. The measures were the Numeric Rating Scale (NRS) and Discomfort Scale-Dementia of the Alzheimer Type (DS-DAT) for self-reported and observational pain, Geriatric Depression Scale Short Form-Korea Version (GDSSF-K) for depression, Barthel Activities of Daily Living (BADL) scale for ADL. The data were analyzed using the Pearson's correlation coefficient and hierarchical multiple regression using the SPSS/PC 20.0 program. The analysis results of the relationship of pain, depression and activities of daily living, both DS-DAT and NRS showed a significant negative correlation with the activities of daily living and a positive correlation with depression. Finally, gender, arthritis, depression, and activities of daily living explained 28.1% of the variance in pain using NRS, whereas depression and activities of daily living explained 21.5% of the variance in pain using DS-DAT. The results highlight the need to develop a pain management program that reduces the depression and promotes the activities of daily living in nursing home residents; hence, a differentiated approach as non-pharmacological interventions is required.

To approach science education for all which has been required in STS program, it is indispensable to develop variously differentiated education courses that are suitable for various students. In order to do that, we have to abstract essential items that are dealt with in common from science textbook which is regarded as the kernel of science education. Then, these items are developed by fitting for each level-STS science study models. The purpose of this study is to improve the level-based investigation competence by applying these models to various level learning. We obtained some results as the following: First, there has been a positive change for attitude to study science in part. Second, we find the materials in our life and this study is relating to science, technique and society. So we find out the fact that there is close connection between science technique and our life. And also it helps encourage to learn. Third, in the process of searching for and producing STS materials, students have a chance to study for themselves by working out self-leading research activity. Finally, students can reduce a preconception that science is difficult by encouraging attitudes to search for and make our problems in our life scientifically and the habits thinking of and understanding our daily life itself in the scientific sight.
