Apple blotch-like symptoms (ABLS) were observed on 'Fuji' apple leaves in Cheongsong, Gunwi and Yeongcheon apple orchards located in Gyeongbuk Province during 2010-2014. Characteristics of ABLS were yellowing, brown spots on leaves, and defoliation, similar to apple blotch diseased (ABD) leaves, which are infected with Marssonina coronaria. It is difficult to differentiate by eye between ABLS and ABD, which has led to misdiagnosis and overuse of fungicides. The present study was conducted to investigate the cause of ABLS using stereomicroscopy, culture isolation, cross-sectional analysis of leaves, and PCR. No acervuli were found on the surface of ABLS leaves and no growth was observed on potato dextrose agar (PDA) plates in culture. Furthermore, cross-sectional analysis revealed similar results, and mycelia were absent in ABLS leaves. By contrast, all these characteristics were present in ABD leaves. Furthermore, no fungi or viruses were detected in ABLS leaves by PCR, suggesting that the disease is not caused by these agents. These findings suggest that ABLS might be a physiological disorder in plants that is distinct from ABD.

Purpose: The study was undertaken to see whether the culturally sensitive education for perinatal care using a face to face approach improves understanding of spouse's culture, knowledge of pregnancy and parenting skills, and self-efficacy among Korean husbands and Vietnamese wives. Methods: This study has a pre- and post-test study design conducted in a total of 13 couples who live in Seoul and agreed to participate. The education program consisted of lecture and hands on practice. The self-administered questionnaires and the checklist developed based on the educational purpose were used to assess the education effects. Results: The knowledge scores on Korean/Vietnamese culture, pregnancy and parenting skills as well as the performance scores on hand washing, pelvic strengthening, feedings and newborn bathing techniques were significantly improved in both husbands and wives after education, but pelvic floor exercises were improved only in wives. Conclusion: Overall, the individual education for culturally sensitive perinatal care was effective in our study participants.

The purpose of this study is restoration for tearing strength of the durable press (DP) finished 100% cotton fabric by enzymatic treatment. Dimethylol Dihydroxy Ethylene Urea (DMDHEU) was used as a DP finish chemical. Enzymes (cellulase, pectinase, protease, lipolase) were selected based on their specific reaction activities. Ideal application of the enzymes for this work was to remove cross-links created by DMDHEU on the surface of the fibers to offer migration property between microstructures of cellulose, yet cross-links that exist inside of the fibers are still remained to impart effect of wrinkle resistance. Physical characteristics (tearing strength, wrinkle recovery, FT-IR) of enzyme treated samples were measured and compared. It was found out that, in case of enzyme treatment, most of enzymes didn't have a great effect on tearing strength, but, in case of Protease, tearing strength increased at DMDHEU 2% treatment. As a result of an experiment on wrinkle recovery of the textiles treated with enzyme making density of DMDHEU different whenever respective experiment was made, it was discovered that density of DMDHEU increased as wrinkle recovery increased and, in the relation to enzyme treatment especially in Lipase enzyme treatment, the lesser density of DMDHEU, the more wrinkle recovery increased.

Bonding strength of a thermal sprayed coating is difficult to measure using a conventional pull-off test method. Scratch test is a potential alternative testing method. An adhesive and a cohesive bond strength of the coating can be measured by the pull-off test while the scratch test performed on the cross-section of the thermal sprayed coating can only demonstrate the cohesive bond strength of the coating. Nevertheless, it is still beneficial to perform the scratch testing on the cross-section of the coating for the sake of comparison thus providing an alternative to the pull-off test. The scratch test method can reduce testing time and cost in the long run due to a significant cost reduction in consumables and energy and time saving from the curing step of the glue used in the pull-off test. This research investigates the possibility of using the scratch test to measure the cohesive bond strength of Mo/NiCrBSi composite coating. The results from the pull-off test and the scratch test indicate that the cohesive bond strengths of the Mo composite coating show similar trend and that the cohesive bond strength are increased when increasing NiCrBSi content.

This study aims to investigate national image of South Korea held by russians. Surveys(based on Free-association Image) and discussion were conducted on LiveJournal (internet blog) with russian netizen. A national image is influenced by a subjective perspective rather than an objective one. Therefore, an image can differ substantially from reality. Futhermore, it takes a long time to change an established image, particularly to a positive image. According to the results, the image of South Korea were dominated by unstable political situations, especially factors related to North Korea. In addition, based on Free-association image, thinking about Korea or Korean, most russians recognize Korea(South) with North Korea. Above all Russians recognize Korea, basing their images on factor of the past or their neighbors-russian korean- or famous Korean brand like Samsung, LG, Hyndai, "Dosirak". Russian netizen did not recognize South Korea as one of leading countries in Asia, paying little attention to South Korea compared to China or Japan. We belive that it is necessary to consider these situations in future efforts to enhance the national image of South Korea.

This paper explores how to teach Chinese, using multi-media resources such as Chinese dramas and focusing on one of Jin Yong's dramas, The Return of the Condor Heroes. The purpose of this study is to develop teaching methodologies for university students learning Chinese through drama to integrate language skills: enhancing communicative competence and understanding Chinese cultures. First, the overview of previous studies provides several cases of foreign language education using drama. Teaching Chinese through drama can be an integrative education because students can develop their communicative competence as well as understand the cultures of the target language. In other words, the contexts of drama may offer rich sources of the history of China, Han Chinese ethnocentrism, and knowledge of Chinese literature as well as geography. Second, this study applies the principles of Tomlinson (2010) for materials development in language teaching into the case of Chinese drama. It concentrates on Jin Yong's The Return of the Condor Heroes that the author has used in the Chinese language courses for three years. It examines the characteristics of the drama for developing effective ways of teaching and learning Chinese language and culture. Furthermore, it discusses the impact of using drama on changes in students' pervasive perceptions about unnecessity of Chinese classical literature. Third, this paper presents some sample lessons which may help teachers to develop understanding of how to organize lessons through drama. Finally, it illustrates university students' opinions about using drama to learn Chinese.

This article aims to explain the 'people-image' of Bakhtin's works in the light of "Transgredience" and "Transition." According to Bakhtin, the real core of every culture is the people. But he did try to answer the question "what is the people?" I think, the secret of Bakhtinian thought is located in the people-image, because it is the one of the territories that have not been explained. For this purpose, we have to examine four images represented by Bakhtin, - rogue, clown, fool, thief. These images are the concrete and individualized images of people, who can characterize the power of transgredience and transition. They commonly act for changing ordinary borders of identities formulated with nationality, property, status, classes, sex and so forth. In this sense, Bakhtin thinks that the masks are the real nature which can show the mutational power of Being. That is the kernel of Bakhtin's people-image that makes and changes every cultural world. When we accept and practise this perspective positively, we will realize that Bakhtin's position is close to the cultural politics, because a practical power of thought cannot help but being political. That's why we have to investigate Bakhtin's people-image from a vantage point of "Transgredience" and "Transition."

The trend of globalization has sharpened the debate on interculturality, which scholars examine from different and often conflicting points of view ('content' vs. 'practice', 'culture-specific' vs. 'universal', 'communication (meta)theory' vs. 'communication practice', 'individual' vs. 'collective', etc.). Whereas all these approaches are necessary to describe the multiple dimensions of interculturality, their dichotomous nature does not help to account for its internal complexity, which cannot be dissociated from the connections that exist among all these dimensions. The difficulty posed by the essentialist interpretations that tend to result from these dichotomies is compounded by the fact that in postmodern debates priority has been given to approaches that emphasize individual or collective agency over structural constraints which have to do with political economy or with cultural and linguistic codes and traditions. This paper aims mainly at suggesting that the dissolution of the boundaries that exist between these approaches should be pursued in order to get a fuller and richer approach to their common object of study. After discussing, by way of illustration, content-based and practice-based perspectives, we suggest that one way of getting beyond these dichotomies consists in focusing on the 'interactional' dimension of interculturality, which means laying emphasis on intersubjectivity and, particularly, on the individual subjects considered as members of different cultural communities who strive to transcend their sociocultural boundaries in order to reach harmonious interactions in a world in which inequality and the de-territorialization of people and cultures are central features.
