Purpose - Media is a significant distributional channel in sport. In terms of determining the influencer in building sport media contents, recent sport media studies have employed agenda-setting theory, assuming media itself as the agenda provider. In a real-world situation, however, sports stars have been deemed key factor determining distribution contents in sport. The starting point of this study is the “tacit premise” of agenda-setting theory. Given the agenda-setting theory, the current study attempted to explore the function of sport stars as an agenda provider, which is a key determinant of sport distribution. Research design, data, and methodology – This study has reviewed articles of Yuna Kim, Sang-hwa Lee, and Hyun-jin Ryu from daily newspapers including as dong-a ilbo and joongang ilbo (2013 to 2017). The study collected data, portable document format (PDF), from the online archive of dong-a ilbo and joongang ilbo. We coded the length of the article, the frequency, the size of the picture, and the structural form of the article. Inter-coder reliability was compared with data previously investigated by the researcher. Inter-coder reliabilities for study 1 and 2 was .89 and .85. To examine hypotheses, descriptive analysis, correlations, and cross-tap analysis were performed. Results – The results partially supported the hypotheses proposing the significant role of sports stars as the agenda setters in distributing sport media contents. In specific, the study found that the number of articles about sports stars prevailed the number of articles about regular athletes. Besides, studies found that the use of photos was more frequent in articles of sports starts than that of regular athletes. In sports newspaper articles, featured story articles were used more than straight-articles for news relating to sports stars. Also, sports newspaper of sports stars contained more information associated within an event rather than outside of an event. Conclusions – In sports journalism, this study challenges the current theory that the media affects the composition and the content of sports coverages. As the principle of the agenda-setting of sports media, the influence of sports stars must be continuously studied along with a follow-up study.
BACTERIA-BASED MICROROBOT FOR CHEMOTAXIS DELIVERY

We proposed a simple microfluidic device that enabled anisotropic absorption of detoxified S.typhimurium bacteria to microcubics so that the particles can swim toward desirable direction by chemotaxis of the bacteria. The speed of the “bacteria-based microrobot” was ~5um/sec which is faster than any prior demonstrations, leading to an effective drug delivery system.

<P>To determine the impact of treatment protocols on the outcome of central nervous system germ cell tumors (CNS-GCTs), we reviewed the medical records of 53 patients who received front-line chemotherapy from September 1997 to September 2006. Pure germinoma, normal alpha-fetoprotein level and beta-human chorionic gonadotropin level <50 mIU/mL were regarded as low-risk features and the others as high-risk. Patients from different time periods were divided into 3 groups according to the chemotherapy protocols. Group 1 (n=19) received 4 cycles of chemotherapy comprising cisplatin, etoposide and bleomycin. Group 2 (n=16) and group 3 (n=18) received 4 cycles of chemotherapy with cisplatin, etoposide, cyclophosphamide and vincristine in the former and with carboplatin, etoposide, cyclophosphamide and bleomycin in the latter. In group 2 and group 3, high-risk patients received double doses of cisplatin, carboplatin and cyclophosphamide. Radiotherapy was given after chemotherapy according to the clinical requirements. The event-free survivals of groups 1, 2, and 3 were 67.0%, 93.8%, and 100%, respectively (group 1 vs. 2, <I>P</I>=0.06; group 2 vs. 3, <I>P</I>=0.29; group 1 vs. 3, <I>P</I>=0.02). Our data suggest that risk-adapted intensive chemotherapy may improve the outcome of patients with malignant CNS-GCTs.</P>

<P><B>Abstract</B></P><P>We report the outcome of 236 pediatric umbilical cord blood transplantations (UCBT) performed in Korea. Given that the sources of the grafts were mostly unrelated donors (<I>n</I> = 226; 95.8%), only the results of unrelated UCBT were included for all statistics. The most frequent primary disease was acute leukemia (<I>n</I> = 167). In total, 91.7% of recipients were seropositive for cytomegalovirus (CMV). The median doses of nucleated cells and CD34+ cells were 4.84 × 10<SUP>7</SUP>/kg and 2.00 × 10<SUP>5</SUP>/kg, respectively. The median times to neutrophil (>0.5 × 10<SUP>9</SUP>/L) and platelet recovery (>20 × 10<SUP>9</SUP>/L) were 18 and 45 days, respectively. Grade 2–4 acute graft‐versus‐host‐disease (GVHD) and chronic GVHD developed in 41.1 and 36.1% of cases, respectively. Forty‐five patients developed CMV disease. The 5‐year overall and event‐free survival were 47.5 and 36.9%, respectively. Multivariate analysis revealed that adverse factors for survival of the whole cohort were total body irradiation‐based conditioning (<I>P</I> = 0.007), salvage transplant (<I>P</I> = 0.001), failure to achieve early complete chimerism (<I>P</I> < 0.0005), and CMV disease (<I>P</I> = 0.001). The outcomes of the single‐ and double‐unit UCBT (<I>n</I> = 64) were similar, while double‐unit recipients were heavier (<I>P</I> < 0.0005) and older (<I>P</I> < 0.0005). We conclude that double‐unit UCBT is a reasonable option for older or heavier children and that the thorough surveillance of CMV infection and the development of an effective CMV therapeutic strategy may be especially important for Korean children, whose CMV seroprevalence exceeds 90%.

Anisotropic Bacterial Adsorbed Micro Chambers by Microfluidic Trapping Array
Keon Huh,Darong Oh,Hyung Jung Yoo,Jong-Mo Seo,Dong-il “Dan” Cho,Sung-Jae Kim 제어로봇시스템학회 2013 제어로봇시스템학회 국제학술대회 논문집 Vol.2013 No.10
Bacteria based biomedical micro-robot is being investigated or proposed to achieve effective and localized drug delivery system due to low toxicity and free of external power sources. In this work, we proposed a simple microfluidic system that enables anisotropic bacterial attachment to the drug containing micro chamber made of biodegradable polymer. A pin-ball type trapper can capture only one micro chamber at a fixed configuration. The efficiency of the trapper was analyzed by monitoring the motion of chambers. More than 70% of trapper was filled with the micro chamber within seconds, leading high throughput applications. We are planning to introduce modified Salmonella bacteria for absorbing them to the specific sides of the micro chamber. After releasing the chamber, one would use it as a microrobot by the chemotaxis of the attached bacteria towards the targeted site.
