Jung, Minsoo,Choi, Mankyu,Lee, Tae-Ro SAGE Publications 2015 Asia-Pacific journal of public health Vol.27 No.2
<P>This study investigated the individual and social determinants of the public’s phobia of infectious diseases in South Korea, where collective action was recently fueled by the public phobia over mad cow disease (bovine spongiform encephalopathy [BSE]). Gender-specific multivariate regression was used to compare the public perception of BSE and highly pathogenic avian influenza (HPAI). The analysis results differentiated between the determinants of the phobia for the 2 diseases, BSE and HPAI (N = 1002). As with HIV/AIDS and leprosy, the public fear of HPAI was expressed as a disease phobia that seeks to ensure the social exclusion of infection sources, whereas the fear of BSE was influenced by social and communication factors. Therefore, BSE, unlike previous HPAI, can be rapidly amplified amid the growing distrust in health communication, in which case the social determinants of disease phobia are associated with communicator trust, social values, and political attitude toward diseases rather than disease perception.</P>
Moon, M. Jae,Lee, Jooho,Roh, Chul-Young SAGE Publications 2014 ADMINISTRATION & SOCIETY Vol.46 No.1
<P>This study reviews research themes and methods used in information technology (IT) in government and e-government research. Although IT/e-government studies (including inward aspects of IT applications in government and e-government studies) continue to increase, they are not comprehensively understood as a subfield within public administration. Based on Rosenbloom’s three competing approaches to public administration (managerial, political, and legal), we investigated the major research themes of IT/e-government studies in public administration. We analyzed 248 IT/e-government articles published in six major public administration journals from 1965 to 2010 to examine IT/e-government research trends in terms of research themes and methods.</P>
Korean Public Administration Research 1999-2009 : Research Themes, Methodologies, and Scholarship
Moon, M. Jae,Kim, Gongrok,Lee, M. Jin SAGE Publications 2014 AMERICAN REVIEW OF PUBLIC ADMINISTRATION Vol.44 No.2
<P>This article examines three major characteristics—themes, research methods, and authorship—of Korean public administration research written in the Korean language during 1999 to 2009. It suggests that this research has evolved and advanced both quantitatively and qualitatively. Recent Korean scholarship can be characterized as consisting of more reform-oriented topics, more quantitative methods, and more diversified authorship. These characteristics were partially caused by increasing social demand for government reform and growing emphasis on methodological rigor in public administration research, as well as increased government research funding for graduate programs. This also concludes that the Korean public administration research has advanced greatly in past decades but needs a better thematic and methodological balance as well as balance between theoretical and prescriptive studies.</P>
Topic-based content and sentiment analysis of Ebola virus on Twitter and in the news
Kim, Erin Hea-Jin,Jeong, Yoo Kyung,Kim, Yuyoung,Kang, Keun Young,Song, Min SAGE Publications 2016 JOURNAL OF INFORMATION SCIENCE Vol.42 No.6
<P>The present study investigates topic coverage and sentiment dynamics of two different media sources, Twitter and news publications, on the hot health issue of Ebola. We conduct content and sentiment analysis by: (1) applying vocabulary control to collected datasets; (2) employing the n-gram LDA topic modeling technique; (3) adopting entity extraction and entity network; and (4) introducing the concept of topic-based sentiment scores. With the query term 'Ebola' or 'Ebola virus', we collected 16,189 news articles from 1006 different publications and 7,106,297 tweets with the Twitter stream API. The experiments indicate that topic coverage of Twitter is narrower and more blurry than that of the news media. In terms of sentiment dynamics, the life span and variance of sentiment on Twitter is shorter and smaller than in the news. In addition, we observe that news articles focus more on event-related entities such as person, organization and location, whereas Twitter covers more time-oriented entities. Based on the results, we report on the characteristics of Twitter and news media as two distinct news outlets in terms of content coverage and sentiment dynamics.</P>

<P>Although job satisfaction is a primary human resource management concern, there is little empirical research considering job satisfaction in non-Western countries. In Korea, reforms aim to make the public service more competitive and diverse and have led to the recruitment of more women and young people. This study uses data from the Korean Income and Labor Panel Study to explore the relationship of age, gender, and service sector with job satisfaction. No substantial difference was found in the perceived job satisfaction of public employees of different ages, but an unexpected negative association was found in a subsample of private employees. Korean public and nonprofit employees are more satisfied with their jobs than private employees are but are less satisfied with their wages than with job security and job content. The study supports the expectation hypothesis and suggests there is a gender effect on job satisfaction, particularly for wages and work environment.</P>
Enzymatic hydrolysis of polyamide fabric by using acylase
Kim, Hye Rim,Seo, Hye Young SAGE Publications 2013 Textile research journal Vol.83 No.11
<P>In this study, we assessed the effectiveness of acylase I from <I>Aspergillus melleus</I> in the treatment of polyamide (PA) fabric. The hydrolytic activity of acylase was evaluated by measuring the number of carboxylate ions released into the treatment liquid and the color strength (<I>K/S</I> value) of α-bromoacrylamide reactive-dyed fabrics. Since acylase hydrolyzed amide bonds in PA fabrics, the larger number of carboxylate ions were released into the treatment liquid and the number of ionic groups formed on the fabric surfaces was increased. The optimal conditions for the enzymatic treatment of PA fabric were determined to be pH 8.0 at 50 with a treatment time of 60 minutes. The hydrolysis products were formed on the acylase-treated fabric surface stably, as demonstrated by the results for wash fastness. The moisture regain and wettability of the fabric improved due to the newly generated ionic groups formed on the fabric surface by acylase hydrolysis.</P>
Effects of fit on pressure distribution and momentum of ballistic body armor vest in jump
Lee, Heeran,Hong, Kyung Hi,Kim, Soyoung,Lee, Yejin SAGE Publications 2013 Textile research journal Vol.83 No.14
<P>The current military ballistic vest, with its ceramic plates, weighs over 8 kg, and there is a gap between the body and clothing owing to the flat shape of the military ballistic vest. Moreover, since the weight is concentrated on the shoulders, it is likely to exacerbate musculoskeletal pains and fatigue. Although reducing the weight of the military ballistic vest is very important for military operations, it is difficult to decrease the weight because the selection of materials and textiles is limited to protecting the wearer against ballistic hazards. Therefore, this study proposes ways to distribute the weight of a ballistic vest more uniformly using three-dimensional (3D) technology, so that comfort is maximized under identical weight conditions. The impact from the military ballistic vest and its vector magnitude, depending on the fit of the military ballistic vest during jumping, were also analyzed. For the experiment, 3D-scanned body data of average Korean males were used to design a military ballistic vest that is well fitted to a real human body. A wear test was also performed to investigate how effectively a fitted military ballistic vest is able to evenly distribute the weight compared to a loosely fitted military ballistic vest. In addition, the pressure sensation of the wearer was analyzed to investigate the overall performance of developed military ballistic vests.</P>

Kim, Su-Hyun,Kwak, Kichang,Jeong, In Hye,Hyun, Jae-Won,Jo, Hyo-Jin,Joung, AeRan,Yu, Eun-Seung,Kim, Ji-Hee,Lee, Sang Hyun,Yun, Sooin,Joo, Jungnam,Lee, Dong-kyun,Lee, Jong-Min,Kim, Ho Jin SAGE Publications 2016 Multiple sclerosis journal: clinical and laborator Vol.22 No.14
<P>Conclusion: CI in patients with NMOSD may be not as common as in patients with MS. MS patients exhibited severe impairment, particularly on learning and memory tests, compared with NMOSD patients. Differential prevalence and patterns of CI between NMOSD and MS patients suggest that the two diseases have different mechanisms of brain injury.</P>
Thermal comfort and waterproof-breathable performance of aluminum-coated polyurethane nanowebs
Kim, Keum Seo,Park, Chung Hee SAGE Publications 2013 Textile research journal Vol.83 No.17
<P>In this study, aluminum (Al) vapor was deposited on the surface of electrospun polyurethane nanowebs in order to improve their thermal comfort while maintaining water vapor permeability. After the deposition, the pore size and air permeability decreased, while the water vapor permeability remained at a level of 5000g/m<SUP>2</SUP> <SUP>·24hr</SUP>. Because of the reflection of the radiation heat, the thermal resistance increased by 30–40% compared with untreated nanowebs. Evaluation of clothing performance using a thermal sweating manikin demonstrated that the water vapor resistance of the deposited nanowebs was lower and the thermal resistance was higher than existing waterproof–breathable textiles.</P>
