Sunyoung Hwang 전북대학교 부설 휴양및경관계획연구소 2015 휴양및경관연구 (J East Asian Landscape Studies) Vol.9 No.4

본 연구의 목적은 도시 재생을 위한 플레이스 브랜딩 구축으로 도시 활성화를 위해 차별화된 플레이스 브랜드 개발 방법을 모색하는 것이다. 이를 위해 성공사례를 토대로 각 도시마다 지니고 있는 문화상징요소를 파악하는 것이 필요함 을 제안하는 것이다. 도시 재생은 쇠퇴하고 낙후된 구도시의 부정적인 이미지를 없애고 문화적, 사회적, 경제적 재활성화 를 추진하는 사업이다. 도시재생이라는 도시발전 전략을 통해 이루어진 효율적인 브랜딩 구축은 도시 경쟁력을 확보하 고 방문자와 거주자를 포함한 도시민의 삶의 질을 향상시킬 수 있다. 플레이스 브랜딩이 성공적이기 위해서는 플레이스 브랜딩 전략을 도입하여 이미지를 향상시키는 이미지 구축 과정이 필수적이다. 플레이스의 핵심 가치를 찾아내고 그 가치들을 수요자들의 요구에 부합시킴과 동시에 그 가치를 증대시키 는 적극적인 전략이 요구되며 이러한 이미지 구축 과정에서 문화상징요소의 활용이 필요하다. 플레이스 브랜딩의 가치는 지역의 문화상징요소들의 상징화와 구체화를 통해 경제적 부가가치 창출에 기여하고 지역 및 도시 브랜드의 가치를 향상시키는 중요한 역할을 하고 있다. 지역의 특성을 파악하는 차별화된 플레이스 브랜딩을 구축하기 위해서는 지역의 문화상징요소들을 파악하고 상대적 중요성을 분석하여 선택적으로 개발하는 것이 필요하다. 결과적으로 지역 고유의 역사성, 특수성, 상징성의 문화를 활용 한 플레이스 브랜딩 전략구축이 있어야 한다. The purpose of this study is to explore the development method of differentiated place branding for the revitalization of city through the establishment of place branding for urban regeneration. It is to suggest the necessity for providing the analysis of cultural symbol elements of each city based on the successful case. The urban regeneration is to eliminate the negative image of decayed and undeveloped old city which is to pursue the process of cultural, social and economic revitalization. By pursuing the strategy of urban development, the establishment of effective place branding is to improve the quality of life and to secure urban competitiveness. For a successful place branding, the strategies of active place branding must be adopted towards the image creation that can further raise the status of a given image. The core value of a place must be recognized and, in the process, this value must be maximized while conforming to the demands of the consumers. It is in this image creation process that the use of cultural symbol elements become a necessity. The value of place branding lies in its important role in raising the brand value of a region or a city. The development of the value of place branding has contributed the creation of economic value added through the materialization and symbolization of local cultural symbol elements. The relative importance of cultural symbol elements will be analyzed to establish differentiated place branding which recognizes local characteristics. As a result, it is necessary to pursue the strategy of place branding by using cultural resource of the historicity, distinctiveness, and symbolism of regions.

Isolation and characterization of bacteriophages specific for<i>Campylobacter jejuni</i>

Hwang, Sunyoung,Yun, Jiae,Kim, Kwang-Pyo,Heu, Sunggi,Lee, Seungdon,Ryu, Sangryeol Wiley (Blackwell Publishing) 2009 Microbiology and immunology Vol.53 No.10

<P>Human infection by Campylobacter jejuni is mainly through the consumption of contaminated poultry products, which results in gastroenteritis and, rarely, bacteremia and polyneuropathies. In this study, six C. jejuni-specific bacteriophages (CPS1-6) were isolated by the spot-on-the-lawn technique from chicken samples in Korea and characterized for potential use as biocontrol agents. All isolated bacteriophages exhibited a high specificity, being able to lyse only C. jejuni, but not other Gram-negative bacteria, including C. coli, Escherichia coli, Salmonella spp., and Gram-positive bacteria. Bacteriophages contain an icosahedral head and a contractile tail sheath in transmission electron microscopy, and possess ds-DNA with an average genome size of approximately 145 kb; therefore, all bacteriophages are categorized into the Myoviridae family. Bacterial lysis studies in liquid media revealed that CPS2 could be used to control the growth of C. jejuni.</P>

Sunyoung Lee,Jinseong Moon,Injong Ha,HaeJoon Hwang,Hyeonyeol Shin 한국육종학회 2014 한국육종학회 심포지엄 Vol.2014 No.07

This study was carried out to analyze correlation between heterosis of F1 hybrids and the genetic distance of parental lines. Growth characteristics such as number of leaves, plant height, bulb diameter, bulb height, bolting rate and marketable yield were examined in 15 F1 hybrids. The genetic distance among one male sterile line and fifteen restorer lines were analyzed with SSR markers. 21 primer pairs amplified polymorphic band and the average number of polymorphic allele was 3.4. As a result of UPGMA cluster analysis, the similarity coefficient value among parental lines ranged from 0.43 to 0.63. Combination of M1 and R14 is high similarity and number of leaves, plant height and yield are 10.2, 66.7cm and 6,818kg·10a-1. The case of the lowest value combination, they are 9.0 and 63.7cm and 7,728kg·10a-1, respectively. The results showed that there are no significant correlations between genetic distance and heterosis of F1 hybrids and only molecular marker does not predict growth traits and yield of onion.

Purpose: The purpose of this study was to systematically review the suicide prevention programs for healthcare personnel to identify contents, formats, and strategies essential for effective suicide prevention programs. Methods: A systematic search using key words in English and Korean was conducted using 10 electronic databases, including EMBASE, MEDLINE, and RISS. Of 794 publications identified, 9 studies were finally included in this systematic review. The Scottish Intercollegiate Guidelines Network (SIGN) was used for the quality assessment. Results: Of the nine experimental studies, seven studies used randomized controlled trials (RCTs), and two used quasi-experimental designs. Overall, suicide prevention programs were found to be effective in improving competencies (e.g., knowledge, communication skills, and attitudes) of healthcare personnel working in diverse settings. Limitations of these studies included a lack of rigorous research designs and reliable and universal outcome measures. Paradoxically, none of the studies were conducted in South Korea, which consistently has the highest suicide rate of all OECD countries. Conclusion: Suicide prevention programs for health personnel can be an effective way to improve competency of healthcare personnel in preventing suicide. These findings will serve as a foundation for the development of suicide prevention programs by Korean healthcare personnel.

This study aims to analyze textual features in compositions written by Chinese international students through the analysis of expository texts, exploring the influence of their native language on the writing. To achieve this, written compositions from 63 intermediate-level Chinese international university students were collected and analyzed using an inductive approach to categorize textual features by type. The research revealed that textual features in the writings of Chinese students could be broadly categorized into paragraph organization and conclusions. Within the domain of paragraph organization, issues were identified with sentence order and the insertion of unnecessary sentences. Furthermore, concluding sentences often exhibited characteristics such as personal content, new information, or functioning as central statements. Additionally, an analysis of Chinese elementary school textbooks was conducted to identify areas where learners' writing was influenced by their native language. Based on these findings, the study proposes educational recommendations for the content and methods of Korean writing courses designed for Chinese international university students. This research is significant in its analytical examination of authentic learner compositions to identify textual features, and its investigation of the impact of Chinese textbooks on the learners' writing. Furthermore, the study provides foundational material for the selection and instruction of educational content in academic-oriented writing courses for learners with a focus on language proficiency goals.

황선영 ( Hwang Sunyoung ) 한국화법학회 2017 화법연구 Vol.0 No.37

This study aims to analyze the genre characteristics of discourse and the use of tenses in television news. The research questions are as follows: a) Are there differences in the use of tenses according to the move of the news? b) Are there differences in the use of tenses according to the topic of the news? For the analysis, 34 evening newscasts from April 19 to April 26, 2017, of three broadcasters were used. Analyzing the use of tenses according to the news topic, it was observed that in the news reporting events or incidents, the past tense functioned as a representation of the foreground; whereas in the news reporting a social phenomenon, the present tenses represented the foreground. Analyzing the use of tenses according to the move of the news, we observed constant movement of the deictic center. The result of this study shows that tenses serve different functions according to the move within the discourse. Moreover, even within the same discourse genre of news report, the type of the news topic defined the utilization of tenses.

This study was conducted to examine whether the social exclusion of individuals influences cognitive social capital from the viewpoint of social integration and whether this relationship is moderated by the generation. The fuzzy set method is applied to measure the multidimensionality of social exclusion. The effects of social exclusion, measured by economic, residential, employment, and health dimensions, on individual trust and reciprocity were analyzed. As a result, social exclusion showed that cognitive social capital is decreased. As a result of analyzing the score by each dimension, the trust level decreased as the exclusion level increased at all levels. In the case of reciprocity, the more excluded from employment and health, the lower the willingness to help others in crisis. As a result of analyzing the moderating effect of the generation, the effect of the social exclusion on the trust reduction is relatively decreased in the industrialized generation (the elderly people). On the other hand, democratic generations (middle-aged) showed that their level of trust decreased sharply compared to other generations when social exclusion exceeded a certain level. Industrialized households had higher reciprocity than other generations when the social exclusion level was low, but reciprocity decreased as the social exclusion experience increased. According to the results of the research, it can be seen that the policy support is needed to escape the social exclusion in order to enhance the social trust and reciprocity of individuals for social integration. From the perspective of the generation, it is necessary to eliminate the social exclusion in order to promote the social trust of the democratic generation (middle-aged generation) and the reciprocity of industrialized households (elderly people).
