이 연구의 목적은 뉴스 미디어를 중심으로 연구되어왔던 적대적 미디어 지각이 트위터에서도 발생하는지, 트위터 메시지에 대한 신뢰도와는 어떠한 관계를 보이는지 살펴보는 것이었다. 문헌 연구를 토대로 개인의 의견 강도, 이슈관여도, 메시지의 도달 범위에 대한 지각, 그리고 정보원에 대한 내⋅외집단 범주화가 적대적 미디어 지각에 영향을 미치는 요소로 설정되었다. 이러한 독립 변인들의 효과를 살펴보기 위해 ‘동성결혼 합법화’와 ‘고소득층 증세’에 관한 이슈를 트위터 메시지로 조작하여 실험 연구를 실시하였다. 실험 결과, 적대적 지각에는 의견 강도가 가장 강한 설명력을 갖는 예측 변인이었고, 신뢰도에는 정보원의 도달 범위와 적대적 지각이 유의미한 영향을 미쳤다. 즉, 해당 이슈에 대해 강한 의견을 가지고 있을수록 적대적 지각이 발생하였고, 정보원의 도달 범위가 클수록, 적대적 지각이 약할수록 신뢰도가 높아졌다. 덧붙여, 독립변인 간 상호작용 효과도 나타났는데, 의견 강도가 적대적 지각에 갖는 영향력은 정보원을 내집단이 아닌 외집단으로 범주화하였을 때, 그리고 고소득층 증세보다는 동성결혼 합법화에 보다 큰 것으로 나타났다. This study examined whether the phenomenon of hostile media perception occurs on Twitter, which was typically observed in news media. For an empirical test, the study utilized the issues of ‘same sex marriage’ and ‘tax increase from the rich’, while employing opinion strength, issue involvement, perception of message source’s power, and categorization of message source as the factors of hostile media perception. The experiment revealed that only the opinion strength significantly, positively predicted the hostile media perception on Twitter. Also, the predictability of opinion strength was stronger in the outgroup categorization and same sex marriage issue conditions than ingroup categorization and tax increase from the rich conditions, respectively. As for message credibility, message source’s power was a positive predictor, while the hostile media perception was a negative one. Implications and limitations of the study were discussed.

These days, the beauty industry has become more specific and professional. As a result, the image of the beauty industry has been influential. This study has attempted to investigate an efficient image management plan in the beauty industry through a theoretical review and analysis on related literature records. First, in terms of the relationship between the quality of service and customer satisfaction, customer satisfaction increased when the expectation of service quality was satisfied. Second, in terms of the relationship between customer satisfaction and customer loyalty, customer satisfaction had a positive effect on customers’ repurchase intention and word-of-mouth. In addition, customer satisfaction directly relates to customer loyalty. Third, image management through the introduction of systematic management and market niche has expanded the domain of differentiated beauty shops through continued development of new manuals as well as technical aspects and introduction of unique beauty salons targeting Customer Relationship Management (CRM) and market niche. Fourth, it has been confirmed that quality of service can be improved through employee education and training.

Purpose: There have been no clinical studies on the characteristics of parenteral nutrition (PN) for adult cancer inpatients in South Korea. The published evidence describing modern PN practices in these patients is also extremely limited. Therefore in this retrospective multicenter cross-sectional study, we aimed to investigate the PN support practice in hospitalized adult cancer patients. Methods: The study included adult cancer patients hospitalized in nine hospitals in South Korea and received PN, during the period from August 1st, 2017 to October 30th, 2017. We evaluated the relevant hospital-based PN practices in this group. Results: Among the 11,580 inpatient admissions during this period, 759 cancer patients received PN (6.6%). The majority of enrolled patients (97.2%) used commercially available PN and 71.2% of these used peripheral PN formulations. The average in-hospital PN duration was 16.1±19.9 days. Patients received only 65.4±25.4% calories of the recommended target calories. The in-hospital mortality of enrolled patients was 26.1%. Conclusion: We conclude that commercial PN is the most common form of PN administered to hospitalized adult cancer patients and the overall in-hospital mortality in the patients using PN is higher in South Korea compared to other countries.

이 연구의 목적은 목표 HRD 발전단계에 따라 차별적으로 적용할 수 있는 성과평가 준거를 탐색하는 것이었다. 연구의 목적을 달성하기 위해 각 개념에 대한 선행연구와문헌을 고찰하였고, 이원분류(two-dimensional classification)를 통해 두 개념을 결합하였다. HRD 성과평가 준거에 대한 이론적 탐색의 과정에서 IPO 모형과 CIPP 모형을 통합하여 조직환경, 투입, 과정, 산출, 결과의 5개 영역을 구성하였고, 이를 구체화하는 과정에서 총 20개 성과평가 항목을 도출하였다. HRD 발전단계에 대한 이론적 탐색 과정에서는 기존 연구들이 발전단계를 구분하는 기준이 모호하다는 점에 근거하여 HRD 영역,그리고 역할과 연계한 발전단계를 제안하였으며, Vendor driven HRD, Self-fulfilling HRD,Systematic HRD, Performance based HRD, Strategic HRD의 다섯 단계로 구성하였다. 두개념을 이원분류하는 과정을 통해 HRD 발전단계에 따른 성과평가 준거를 제안하였으며, 이를 현장에서 활용하기 위한 절차로 목표 HRD 발전단계 설정, 평가항목별 가중치설정, 평가항목별 지표 결정, 평가 실행의 4단계를 제안하였다. 이 연구 결과는 특정조직의 상황과 HRD에 대한 목표에 적합한 성과평가 준거를 선택하고, 평가를 실행하기 위한 기초자료로 활용될 수 있을 것으로 기대한다. The purpose of this study was exploring evaluation criterion for HRD performance in graded approach according to aimed HRD development stages. We reviewed literatures about HRD performance evaluation and HRD development stages, and combined those two terms by using two-dimensional classification technique. In the process of reviewing literature about HRD performance evaluation criterion, we proposed 5 domains of evaluation criterion including organizational environment, input, process, output, and outcome by analyzing IPO, and CIPP models. Also, we developed twenty items for evaluating HRD performance such as leadership, HRD system, training and development, career development. On the other hand, we found out that HRD development stages in previous literatures had limitation of vagueness in classification of the stages. Therefore, we proposed HRD development stages tied with domains of HRD, and role of HRD practitioner, which are vender driven HRD, self-fulfilling HRD, systematic HRD, performance based HRD, and strategic HRD. 4 steps for utilizing proposed criterion were proposed, they are goal setting, weight setting, indicator setting, implementation in order. We expect that it could be utilized in effort to selecting appropriate performance evaluation criterion for developmental objectives of corporate’s HRD system.

한국인 환자에 있어서 아미노글라이코사이드의 약동학적 변수를 이용한 반코마이신 약동학 예측

Aminoglycosides (AG) and vancomycin are frequently prescribed for the treatment of serious bacterial infections. Since both agents have similar pharmacokinetics, it would be desirable to estimate vancomycin's pharmacokinetic parameters by using the patient's measured aminoglycoside pharmacokinetic parameters or vice versa. The objectives of this study were to determine if pharmacokinetic relationships exist between AG and vancomycin with respect to pharmacokinetic parameters in Korean patients in phase Ⅰ and to evaluate the clinical utility of these relationships by applying the derived regression equations to a different patient group in phase Ⅱ. 81 patients in phase Ⅰ and 39 in phase Ⅱ receiving concurrent intravenous vancomycin and AG were enrolled in this retrospective study. Steady-state serum concentrations of AG and vancomycin were obtained and pharmacokinetic parameters (Ke, t_(1/2), Vd, Cl) were calculated using first-order pharmacokinetic equations. In phase Ⅰ, there was significant linear correlation between AG and vancomycin pharmacokinetic parameters. The pharmacokinetic parameters of vancomycin derived from AG were superior to those derived from creatinine clearance (Clcr). Correlation coefficient between Ke, t-(1/2), Vd, and Cl values of AG and vancomycin were 0.862, 0.874, 0.438, and 0.787, respectively. Correlation coefficient between Ke, t_(1/2), Vd, and Cl values of vancomycin and those derived from Clcr were 0.728, 0.622, 0.408, and 0.675, respectively. In phase Ⅱ, the correlation between pharmacokinetic parameters of AG and vancomycin may be beneficial for predicting pharmacokinetics of vancomycin, especially in Ke when AG concentrations have already been obtained. Regression equations derived from correlation between AG and vancomycin were less biased in Ke and more precise in Vd. But, vancomycin's Vd and Cl from current regression equations were slightly overpredicted. Thus, revised regression equations ablout predictions of Vd and Cl, and its prospective evaluation will be completed. In conclusion, regression equations derived from AG may be safety used in predicting vancomycin pharmacokinetic parameters.
