오경수(Kyung-Soo Oh) 한국콘텐츠학회 2012 한국콘텐츠학회논문지 Vol.12 No.9

본 연구는 N스크린 서비스가 기존 서비스와 차별성을 가진 새로운 서비스라는 점에서 기술수용모델에 입각하여 N스크린 서비스 수용의도에 영향을 미치는 요인을 탐색하는 것이다. 이를 위해 온라인 서베이를 통해 435명의 N스크린 서비스 잠재적 수용자로부터 자료를 수집했다. 연구결과 자기효능감과 지각된 상호작용성은 지각된 사용용이성에 그리고 서비스 다양성, 지각된 상호작용성, 지각된 사용용이성은 지각된 유용성에 정적 영향을 미쳤다. 반면 사회적 영향은 지각된 유용성에 부적 영향을 미쳤다. 한편, 지각된 사용 용이성과 지각된 유용성은 N스크린 서비스 수용의도에 긍정적 영향을 미치는 것으로 나타났다. 이런 점에서 N스크린 서비스 확산을 위해서는 시간과 장소에 관계없이 수용자 중심의 다양한 콘텐츠를 양방향으로 편리하게 이용할 수 있다는 인식을 갖게 하는 것이 필요하다. Using technology acceptance model, this study investigates the factors affecting N-screen service adoption. We collected 435 available answers from potential users through systematic online survey. Results show that self-efficacy and perceived interactivity factors had positive effects on perceived ease of use. In addition, service variety, perceived interactivity, perceived ease of use factors had positive effects on perceived usefulness. Yet social effect factor had negative effect on perceived usefulness. On the other hand, perceived ease of use and perceived usefulness had positive effect on the intention of use. In conclusion, to improve the intention to use N-screen service, it is necessary to make users convinced that N-screen service can give customized contents and interactive information regardless of time and place.

정부가 정책PR을 수행하는 이유는 국민의 정책지지와 정부신뢰를 얻기 위한 것이다. 정책지지와 정부신뢰는 정부가 정책을 입안하고 수행하는데 원동력이 되기 때문이다. 이런 점에서 본 연구는 동반성장 정책을 중심으로 정책PR이 정책지지, 정부신뢰에 미치는 영향을 분석하였다. 연구결과, 첫째 동반성장 정책PR활동과 정책PR의 성과에 대해 긍정적인 인식을 가질수록 동반성장 정책과 동반성장 정책지지에 긍정적인 영향을 미쳤다. 둘째, 동반성장 정책에 대해 긍정적인 인식을 가질수록 동반성장 정책지지가 높아졌다. 셋째, 동반성장 정책지지가 높을수록 정부신뢰(전문성, 윤리성, 신뢰성)에 긍정적인 영향을 미쳤다. 이러한 결과는 정책PR이 정책지지, 정부신뢰를 이끌어내는 효과적 수단이라는 점을 보여준다. 나아가 정부신뢰제고를 위해서는 정책PR 뿐만 아니라 정책의 투명하고 공정한 집행이 뒷받침되어야 한다. Government has been doing policy PR to acquire policy support and government trust of people. Because it is believed that policy support and government trust of people can be a driving force of government activity. In this perspective, this study analyzed the effects of government’s policy PR on the policy support and government trust of people focusing on the corporation partnership policy. According to the results, first people who have more positive attitude to the policy PR activity and its result, they have more positive attitude to the policy and its support. Second, people who have positive attitude to the corporation partnership policy, they have more positive attitude to the policy support. Third, people who have more positive attitude to policy support, they have more government trust(professionalism, ethicality, reliability). These results show that policy PR is effective method for inducing policy support and government trust of people. And for improving government trust. it is needed not only policy PR but also fair and transparent execution of policy.

PPL (Product Placement) and Virtual AD expose products, trademarks, and so on in the program. Therefor those can have a high advertising effect for ad agents, however viewers are likely to get frustrated by them. Thus, it is important to regulate the proper level of deliberation on those types of ads not to interfere with the viewing flow, and yet contribute to expand ad market. The study conducted a content analysis on the outcome of the review by the Korea Communications Standards Commission (KCC) from 2015 to 2016, and conducted a survey for investigating viewers’ recognition about violation cases of those ads. As results, first, content analysis shows that the number of ad effect violation cases decreased from 357 in 2015 to 173 in 2016. Number of violation cases of PPL and Virtual AD are 97 and 10 each. Violations of reporting sector were reduced in Cable TV. Ad effect violations have been lowered from a state recommendation by resolution but PPL violations received relatively hight sanctions such as cautions and warnings. This is explained by the stricter standard applied by regulators according to the establishment of PPL. According to the analysis of the inmate, PPL violation cases were highly recognized by female viewers in their 20s and 30s. Virtual ad violation cases were generally not recognized as disruptive of audiences’ viewing flow. However, survey respondents said that repeated exposure to product names using subtitles, voice, and props may affect the viewing flow. They also said even though PPL disturbs viewing flow, it is still acceptable. These results show that regulators should regulate repeated exposure of products and trademarks that can disturb audience viewing flow and broadcaster tried to minimize PPL and Virtual AD when they produce programs.

Background/Aims: Despite improved revascularization techniques, the clinical outcomes of patients with diffuse coronary artery lesions after percutaneous coronary intervention are unsatisfactory. However, few studies have compared the efficacy of first- and second-generation drug-eluting stents (DES) in patients with diffuse long coronary artery lesions. Methods: Between January 2006 and July 2012, 364 patients who were treated with DES for long coronary artery stenosis (> 30 mm) were enrolled in this study and assigned to either Group I (first-generation DES, 62.3 ± 10.4 years, 136 males, n = 183) or Group II (second-generation DES, 64.3 ± 10.7 years, 134 males, n = 181). The incidence of major adverse cardiac events (MACE) was compared between the two groups over 2 years of follow-up, and predictive factors associated with MACE were evaluated through a multivariate analysis. Results: Although several coronary angiographic characteristics were different between the two groups, most demographic and baseline clinical variables were the same. The cumulative incidence of MACE was significantly higher in Group I than in Group II (25.7 vs. 6.6%, p < 0.001), mainly due to reduced target lesion revascularization (21.9 vs. 2.2%, p < 0.001). According to the results of the multivariate analysis, the use of a paclitaxel-eluting stent (PES) (hazard ratio [HR], 5.168, 95% confidence interval [CI], 2.515-10.617, p < 0.001), decreased left ventricular function (≤ 45%, HR, 3.586, 95% CI, 1.839-6.990, p < 0.001), and diabetes mellitus (HR, 2.984, 95% CI, 1.605-5.548, p < 0.001) were independent contributors to MACE.

We report on the surface proputies of the films composed of polysiloxane and trimethoxyperfluorosilane(TMPFS). In this study, the PFS was introduced in order to enhance soil-proof property of siloxane polymer. Surface properties of the mixture were investigated. Contact and sliding angle measurements were done in order to investigate the anti-soil, and soil release properties, respectively. The surface free energy of siloxane polymer was decreased remarkably by incorporation of small quantity of PFS with the increment of contact angle and decrease of sliding angle. The TMPFS/Polysiloxane mixture film may provide a great opportunity for the antisoil applications.

Purpose: The purpose of this study was to compare the clinical results of absorbable knot-tying and absorbable knotless suture anchors in arthroscopic Bankart repair. Materials and Methods: This study compared the patients who underwent arthroscopic Bankart repairs using absorbable knottying suture anchors (59 patients: KT Group), and absorbable knotless suture anchors (52 patients: KL Group). Preoperative and postoperative evaluations were performed by Rowe scores, patient satisfaction score, visual analogue scale (VAS), American shoulder and elbow surgeons (ASES) score, range of motion (ROM), and re-dislocation rate. Results: Postoperative VAS, Rowe scores, ASES score were significantly not different between the 2 groups (VAS: p=0.250, Rowe score: p=0.412, ASES: p=0.052). Mean postoperative VAS was 0.5 in KT Group and 0.8 in KL Group (p=0.250), and limited ROM was noted only in one patient in KL Group. Mean Rowe score was 94.3 in KT Group and 96.3 in KL Group (p=0.412), and mean ASES score was 97.3 in KT Group and 94.0 in KL Group (p=0.052). Re-dislocation rate were no different between the 2 groups. Conclusion: There were no differences in clinical outcomes and re-dislocation rate between Knot-Tying and Knotless repairs.

The purpose of this study is to review what kind of interpretation is possible in relation to adopt prohibited acts regulation to broadcasting law. Recently, regulatory agency planned to introduce prohibited acts to broadcasting law and prepared a draft. However, draft regarding prohibited acts in broadcasting law raise some issues as following aspects. First, prohibited acts request broadcasting players not to violate the variety, fairness, independence of broadcasting. But, the concept of variety, fairness, independence of broadcasting is so ambiguous that it is difficult to judge whether the broadcasting players violated prohibited acts clauses or not. Second, draft take a view of content as an essential facilities. But this perspective raise an issues that broadcasting content don`t meet the essential facilities judgement standard like ``essential``, ``unduplicable``, ``unsubstituble``. Also regulation content as a compulsory facilities may infringe the autonomy and property right of broadcasting players. Third, draft imposed broadcasting players the burden of proof that there are no unfair contract in providing broadcasting channel and program. In that case, there will be offense and defence between broadcasting players and regulatory agency because proof method is not concrete. Therefore, in case of introducing prohibited acts to broadcasting law, it need more clear about prohibited acts judgment standard, content as an essential facilities judgment standard, responsibility and method for illegality standard.

Eight strains of multidrug-resistant (MDR) Salmonella typhi were isolated from Kyonggi area during January-February, 1997. They were resistant to ampicillin, amoxicillin, carbenicillin, tetracycline, chloramphenicol, trimethoprim/sulfamethoxazole, trimethoprim. Eight strains had one plasmid respectively which size was approximately M.W 220 kb and showed same restriction pattern by endonuclease HindIII. The plasmid was similar to the plasmid in size that was related to multidrug resistant S. typhi isolated from southeast Asia. It were transferred by conjugation to recipient E. coli K-12 in frequency of $2.43{\times}10^4-1.73{\times}10^{-2}$ and transconjugant showed same drug-resistant pattern with donor cells. All of 8 strains produced ${\beta}$-lactamase that was assummed to TEM-l type by isoelectric focusing and PCR.
