The Influence of a Professional Sport Team’s Philanthropic Initiative on Fans’ Corporate Social Responsibility (CSR) Participation Intention

Within corporate social responsibility (CSR) research, there has been significant evidence of the positive impacts that CSR could bring to businesses. However, few studies, especially in the context of sport, have focused on how CSR benefits an actual social cause. Therefore, through a three-article format, the overall purpose of the dissertation is to examine how a professional sport team could use its CSR as a social marketing strategy to increase its fans’ willingness to participate in the team’s CSR program in contributing to a specific social cause. Specifically, Article 1 assesses whether CSR participation intention significantly differs among fans with varying psychological connection levels to a sport team. Article 2 examines how fans’ trust in a sport team increases their CSR participation intention, especially among fans with a low psychological connection to a sport team. Lastly, Article 3 investigates how fans’ perceived CSR authenticity plays a significant role in the overall study findings. The study findings: (a) demonstrate that fans are more likely to participate in a sport team’s CSR program when they are aware of the philanthropic activity engaged by the team and that CSR participation intention was higher for fans more loyal to the team, (b) provide evidence that enhancing fans’ trust in the team helps increase CSR participation intention, especially among those having a lower psychological connection to the sport team, and (c) emphasize the importance of authenticity within a sport team’s CSR initiative, where fans develop trust in the team to a similar extent for all fan groups, thus, increasing the likelihood for fans to participate in the team’s CSR program

Acute dystonia by droperidol during intravenous patient-controlled analgesia in young patients.

Patient-controlled analgesia (PCA) is an important means for postoperative analgesia with parenteral opioid. However, postoperative nausea and vomiting (PONV) remains a major problem with a PCA system. Droperidol is used in PCA to prevent PONV. Extrapyramidal reactions by droperidol are, however, occasionally induced. We describe two cases of severe extrapyramidal hypertonic syndrome with an intravenous administration of droperidol in PCA in young patients, following orthopedic surgery

System Coverage and Capacity Analysis on Millimeter-Wave Band for 5G Mobile Communication Systems with Massive Antenna Structure

The use of a millimeter-wave band defined as a 30–300 GHz range is significant element for improving performance of 5th generation (5G) mobile communication systems. However, since the millimeter-wave signal has peculiar propagation characteristics especially toward non-line-of-sight regions, the system architecture and antenna structure for 5G mobile communications should be designed to overcome these propagation limitations. For realization of the 5G mobile communications, electronics and telecommunications research institute (ETRI) is developing central network applying various massive antenna structures with beamforming. In this paper, we have introduced the central network and evaluated the system coverage and capacity through C++ language-based simulations with real geospatial information

Multiplex polymerase chain reaction test for the diagnosis of acute viral hepatitis A

Background/AimsThe early diagnosis of acute hepatitis A (AHA) is hindered because serum IgM against hepatitis A virus (HAV) can yield false-negative results during the window period. This study evaluated the diagnostic accuracy of a polymerase chain reaction (PCR) kit for HAV RNA for the diagnosis of AHA.MethodsSamples were collected from 136 patients with acute severe hepatitis at their admission to Asan Medical Center between June 2010 and July 2010. Samples were analyzed for serum IgM anti-HAV using an immunoassay test and for qualitative HAV RNA using the Magicplex HepaTrio PCR test kit. The diagnostic accuracies of these methods were tested on the basis of clinical and laboratory diagnoses of AHA.ResultsThe concordance rate and kappa value between IgM anti-HAV and HAV RNA PCR were 88.2% and 0.707, respectively. For the diagnosis of AHA, the sensitivity and specificity of IgM anti-HAV were 90.7% and 100%, respectively, when an "equivocal" result was regarded as positive; and 79.1% and 100%, respectively, when an "equivocal" result was regarded as negative. The sensitivity and specificity of HAV RNA PCR were 81.4% and 100%, respectively. All four patients with negative IgM anti-HAV and positive HAV RNA PCR results and all four patients with equivocal IgM anti-HAV RNA and positive HAV RNA PCR results were eventually diagnosed with AHA.ConclusionsThe qualitative HAV RNA PCR test has an equivalent diagnostic accuracy for AHA compared to IgM anti-HAV and may be more sensitive during the window period

Optical Coherence Tomographic Finding in a Case of Macular Coloboma

PURPOSE: To report the optical coherence tomography (OCT) findings in a patient with unilateral macular coloboma. METHODS: A 12-year-old male was presented with macular coloboma in the left eye. The optical coherence tomography was performed with fluorescein angiography (FA). RESULTS: The OCT revealed the crater-like depression in the macula, demonstrating atrophic neurosensory retina, and an absence of retinal pigment epithelium and choroid in the lesion. FA showed hypofluorescence corresponding to the size of the lesion in both early and late frames without leakage of dye at any stage. CONCLUSIONS: The OCT can be beneficial to confirm the diagnosis of macular coloboma

THE EFFECTS OF WHEELCHAIR CAMBER AND HANDRIM SIZE IN WHEELCHAIR BASKETBALL MOVEMENT

Improving the wheelchair design can be an important determinant of high performance in the wheelchair basketball. Researchers have focused on increasing the efficiency of the wheelchair, looking at the factors such as the seat position, handrim size, and wheel camber. Most handrim and wheel chamber studies, however, have focused only on the propulsive phase. Quick turn as well as fast propulsion is essential to the success in a wheelchair basketball game and the energy efficiency becomes particularly important in a prolonged wheelchair use. The purpose of this study was to investigate the effects of wheelchair camber and handrim size on the linear propulsion, turn velocity, and efficiency
