본 연구는 항공사 승무원의 자기효능감과 직무성과의 관계에서 직무스트레스의 매개효과에 대해 분석하였다. 이를 위해 국내외 항공사 승무원을 대상으로 2023년 10월 11일부터 17일까지 설문조사를 실시하였고, 유효한 190부의 응답 자료에 대하여 SPSS 21.0을 이용하여 빈도분석, 탐색적 요인분석, 신뢰도 분석, 상관관계분석, 회귀분석을 실시하여 다음과 같은 연구 결과를 도출하였다. 가설검증 결과 자기효능감은 직무스트레스의 하위요인인 대인관계관련 스트레스에 부(-)의 영향을 미치는 것으로 나타났고, 자기효능감은 직무성과에 정(+)의 영향을 미치는 것으로 나타났다. 또한, 대인관계관련 스트레스는 직무성과에 부(-)의 영향을 미치고, 자기효능감과 직무성과의 관계에서 대인관계관련 스트레스는 매개효과를 보이는 것으로 나타났다. 본연구는 항공사 승무원의 자기효능감과 직무스트레스 및 직무성과 간의 영향 관계를 분석함으로써 항공사 승무원 인적자원 관리에 관한 시사점을 제시하는데 연구의 의의가 있다. 고객 접점에서 서비스의 핵심적인 역할을 담당하는 승무원의 개인적 성과와 조직적 성과는 항공사의 경영성과에 상당한 영향을 미친다고 할 수있다. 그러므로 본 연구 결과는 항공사 승무원 교육훈련원 및 인사 담당 부서에서 효율적인 인적자원 관리를위한 기초자료로 활용할 수 있다. This study analyzed the mediating effect of job stress in the relationship between the self-efficacy and job performance of flight attendants. A survey was conducted, and 214 questionnaires were collected from October 11 to 17. A total of 190 copies contributed to the final analysis data and were analyzed using the SPSS 21.0 statistical program. The data analysis was performed via frequency analysis, reliability tests, exploratory factor analysis, correlation analysis, multiple regression analysis, and three-step mediated regression analysis. The results of this study are shown below. Hypothesis testing has shown that self-efficacy has a negative(-) effect on interpersonal stress and self-efficacy has a positive(+) effect on job performance. In addition, interpersonal stress has a negative(-) effect on job performance, and interpersonal stress has a mediating effect in the relationship between self-efficacy and job performance. This study aims to improve airline service quality by establishing a program that can increase self-efficacy in airlines and hiring talented people with high self-efficacy. Therefore, the results of this study can be used to obtain implications for efficient human resource management in airline flight attendant training centers and human resources departments. In other words, airlines can conduct more precise personality tests to hire flight attendants with high self-efficacy and apply various leisure-related programs to reduce job stress during work.

박현정,황애경,김아름,김수현,김은화,조상헌,김종률,최상민,정진아,진석준,배균섭,임형석 대한임상약리학회 2016 Translational and Clinical Pharmacology Vol.24 No.1

Simvastatin is a lipid-lowering drug that is metabolized to its active metabolite simvastatin acid (SA). We developed and validated a sensitive liquid chromatography–tandem mass spectrometry (LC/MS/MS) method to quantitate SA in human plasma using a liquid–liquid extraction method with methanol. The protonated analytes generated in negative ion mode were monitored by mul-tiple reaction monitoring. Using 500-mL plasma aliquots, SA was quantified in the range of 0.1–100 ng/mL. Calibration was performed by internal standardization with lovastatin acid, and regression curves were generated using a weighting factor of 1/x². The linearity, precision, and accuracy of this assay for each compound were validated using quality control samples consisting of mixtures of SA (0.1, 0.5, 5, and 50 ng/mL) and plasma. The intra-batch accuracy was 95.3–107.8%, precision was –2.2% to –3.7%, and linearity (r²) was over 0.998 in the standard calibration range. The chromato¬graphic running time was 3.0 min. This method sensitively and reliably measured SA concentra¬tions in human plasma and was successfully used in clinical pharmacokinetic studies of simvastatin in healthy Korean adult male volunteers.

본 연구에서는 Weinstein과 Mayer(1986)의 인지적인 정보처리 모형에 준하여 인지학습전략의 적용 효과에 영향을 줄 수 있는 영향요인으로써 학업수준 및 학교 급에 따른 효과를 종합하고 더불어 인지학습전략의 적용 영역별 효과를 분석하였다. 본 연구에서는 국내에서 1990년부터 2004년까지 최근 15년 간 인지학습전략을 다룬 학술지 논문 50편을 대상으로 총 97개의 효과크기를 구하였다. 그리고 이들을 종합하여 평균 효과크기를 구하고, 학업 수준 및 학교 급에 따른 세부전략(정교화전략, 조직화전략, 상위인지학습전략, 정의적 전략, 통합전략)별 효과크기와 함께 적용영역(학업성취, 전략사용, 인지적 능력, 정의적 영역)별 세부전략의 적용효과를 구하였다. 본 연구 결과는 다음과 같다. 첫째, 인지학습전략의 전체 평균효과크기는 .92(U3=82%)로 나타났으며, 기존 학위 논문을 분석한 결과에 비해 학술지를 대상으로 분석한 본 연구에서의 인지학습전략의 효과크기가 상당히 높게 나타났다. 둘째, 세부 전략별로는 정교화전략, 상위인지학습전략, 정의적 전략 그리고 여러 전략을 함께 사용한 통합적 전략이 95%의 신뢰범위 내에서 .95-1.16의 유의한 효과크기를 나타냈다. 셋째, 학업수준별로 인지학습전략의 적용효과를 분석한 결과 일반학생은 .80, 그리고 학습장애 학생은 1.29로 나타났다. 넷째, 학교 급별로 인지학습전략의 적용효과를 살펴보면 95%의 신뢰범위에서 .72-1.20의 유의한 효과크기를 나타냈다. 중학교를 제외한 나머지 학교 급에서 인지학습전략의 적용효과가 큰 것으로 나타났으며 특히 초등학교 저학년과 고학년에서 인지학습전략을 적용한 경우 각각 1.24와 1.04로 매우 큰 효과크기를 나타냈다. 다섯째, 적용영역별로는 학업성취, 전략사용, 인지적 능력, 정의적 영역 에 걸쳐 95%의 신뢰구간에서 .82-1.44의 유의한 효과크기를 나타냄으로써 인지학습전략이 4개 적용영역에서 매우 효과가 있는 것으로 나타냈다. 그 외 인지학습전략은 특히 초등학교시기에 학업성취에 미치는 영향이 매우 컸다. 초등학교 고학년 이후에는 전반적으로 인지학습전략의 활용이 전략사용능력에 미치는 효과의 크기가 두드러졌으며, 중학교를 제외하면 인지학습전략의 활용이 정의적 영역에 미치는 효과의 크기도 .81-1.69에 걸쳐 큰 것으로 나타났다. The purpose of this study is to synthesize the cognitive learning strategy intervention studies conducted in Korea between 1990 and 2004, using meta-analysis. By the pre-established systematic criteria, 50 articles were selected and 97 effect sizes from the identified studies were calculated. Effect size is calculated using 'the Cohen's d'(Cooper & Hedges, 1994). The research questions of the present study are as follows: (a) Are cognitive learning strategies generally effective? (b) What type of cognitive learning strategy is most effective? (c) Do different types of cognitive learning strategies have differential effects by the applied domains, grade levels, and achievement levels? The results of the study indicate that, first of all, the overall cognitive learning strategies (97ESs) yield a significant effect size (ESsm=.92). According to Cohen's (1988) rule, this ES is considered "very large". Second, each strategy (elaborative strategies, organized strategies, meta-cognitive strategies, affective strategies, and combined strategies) has a significant effect size and combined strategies (ESsm=1.10), affective strategies (ESsm=.86), and meta-cognitive strategies (ESsm=.99) have very large effective effect size. Third, for students with learning disabilities, the meta-cognitive and combined strategies, applied to cognitive ability and efficacy of using learning strategy domain, are very effective (ESsm=1.61, 1.42). Forth, the effect of cognitive strategies is very large to students in all grades, except for middle school students. The effect size of middle school has a moderate size (ESsm=.72). Lastly, the implications for the application of different cognitive learning strategies were discussed.

Aims: This study was aimed to characterize the population pharmacokinetics of Arimidex® (anastrozole) which has been administered to healthy Korean male volunteers. Methods: We have committed population pharmacokinetic analysis using NONMEM® VII with 408 plasma concentration data obtained from subjects who were administered with reference drug Arimidex® in a randomized, double-blind, two-way crossover bioequivalence trial conducted in Asan Medical Center. We estimated the parameters by first-order conditional estimation (FOCE) method, and then, observed the change of objective function values which had been calculated by using different compartment models, and explored the significant covariates. To evaluate the suitability and stability of final population model, we performed bootstrapping and visual/numerical predictive checks using Wings for NONMEM and Perl-speaks-NONMEM software. We simulated the plasma concentration corresponding to daily doses of anastrozole 1 mg through 10 days. Results: The plasma concentration data of Arimidex® is best fitted by first-order two-compartment linear model. The estimated absorption rate constant value is 0.23 h-1, and the final estimates for the volume of distribution of central and peripheral compartment is calculated as 5.12 L and 319 L,respectively. Conclusions: We successfully constructed the final population pharmacokinetic model of Arimidex® in this study, which could be useful for various purposes such as Monte-Carlo simulation for the plasma concentration-time profiles of Arimidex®.
