이상기(Lee, Sang-Ki),구자원(Gu, Ja-Won) 한국경영교육학회 2020 경영교육연구 Vol.35 No.1

[연구목적] 본 연구는 법률서비스 조직의 내부품질이 직원 및 고객의 만족도와 충성도에 미치는 영향을 분석하고, 그에 따른 시사점을 찾기 위하여 실증분석을 수행하였다. [연구방법] 본 연구를 위하여 서비스-수익 체인 모델을 활용하였으며, 183명의 변호사, 변리사, 기타 전문가들을 대상으로 설문을 수행하였으며, 분석을 위하여 SPSS와 AMOS 버전 25를 사용하였다. [연구결과] 실증분석 결과 서비스제공 준비수준은 직원만족도, 직원층성도, 고객충성도에 정(+)의 영향을 보였고, 고객만족도에는 유의미한 영향을 보이지 않았다. 내부서비스 품질은 직원만족도, 직원충성도, 고객만족도, 고객충성도 모두 유의미한 영향을 갖지 않는 것으로 나타났다. 서비스 생산성 및 품질은 고객만족도와 고객충성도에 정(+)의 영향을 미치는 것으로 나타났고, 직원만족도 및 직원충성도에는 유의미한 영향을 보이지 않았다. 서비스가치 전달은 고객만족도에 정(+)의 영향을 갖는 것으로 분석되었지만, 직원만족도, 직원충성도, 고객충성도에는 유의미한 영향을 갖지 않는 것으로 나타났다. 직원만족도와 고객충성도는 경영성과에 정(+)의 영향을 보였고, 직원충성도와 고객만족도는 경영성과에 영향을 미치지 않는 것으로 나타났다. [연구의 시사점] 본 연구에서는 선행연구에서 제시되는 내용과는 일부 다른 결과가 도출되었다. 이것은 법률서비스 및 서비스 제공자의 특수성에 기인한 것으로 판단된다. S-PC 모델이 단일 모델로 모든 성과경로를 설명하는 데에는 한계가 있다고 지적한 선행연구의 내용과 부합한다. S-PC 모델의 장점과 한계를 같이 이해하고, 산업과 기업(조직)의 특수성을 고려한 추가적인 검토가 함께 전략에 반영되어야 한다고 제시한다. [Purpose] This study conducted empirical analysis to analyze the impact of internal quality of legal service organization on employee and customer satisfaction and loyalty, and to find any implications accordingly. [Methodology] The Service-Profit Chain model was used to carry out this empirical study. For this study, 183 responses from lawyers, patent attorneys, customs agents, para-legals, patent technology experts, and legal support staffs were analyzed. A total of 20 hypotheses were set up and tested to verify. [Findings] As a result of the empirical analysis, the level of readiness for service provision had a positive effect on employee satisfaction, employee loyalty, and customer loyalty, but not on customer satisfaction. In terms of internal service quality, it had no meaningful effect on employee satisfaction, employee loyalty, customer satisfaction, and customer loy2alty. Service productivity and quality were found to have a positive effect on customer satisfaction and customer loyalty, but not on employee satisfaction and employee loyalty. Service value delivery had a positive effect on customer satisfaction, but did not have a meaningful effect on employee satisfaction, employee loyalty, and customer loyalty. Employee satisfaction and customer loyalty had a positive effect on operational performance, however employee loyalty and customer satisfaction did not affect operational performance. [Implications] This study has shown some different results from those generally understood due to the characteristics of the service and the propensity of the service provider. The research results are consistent with the findings of previous studies, which point out that the S-PC model, as an integrated single model, has limitations in explaining all performance path. This study explains the limitations of the S-PC model and suggests that additional considerations should be taken into account in the service strategy, while taking advantage of the merits as an integrated model and at the same time taking into account the specificity of each industry or organization.

이상기,최영식,Lee, Sang-Ki,Choi, Young-Shig 한국정보통신학회 2012 한국정보통신학회논문지 Vol.16 No.12

본 논문에서는 기존의 fractional-N 위상고정루프의 가장 큰 문제점인 fractional 스퍼를 억제하기 위해 위상차-전압 변환기(Phase Difference-to-Voltage Converter : PDVC)를 도입하였다. PDVC는 위상주파수 검출기 출력 신호의 위상차에 따라 전하펌프의 전류량을 조절한다. 제안한 구조는 위상 주파수 검출기(phase frequency detector) 신호들의 위상차가 커지면 전하펌프(charge pump) 전류를 감소시켜 fractional 스퍼를 줄일 수 있는 구조이다. 회로는 1.8V $0.18{\mu}m$ CMOS 공정의 파라미터를 이용하여 HSPICE로 시뮬레이션을 수행하고 회로의 동작을 검증하였다. In this paper, a Phase Difference-to-Voltage Converter (PDVC) has been introduced into a conventional fractional-N PLL to suppress fractional spurs. The PDVC controls charge pump current depending on the phase difference of two input signals to phase frequency detector. The charge pump current decreases as the phase difference of two input signals increase. It results in the reduction of fractional spurs in the proposed fractional-N PLL. The proposed fractional-N PLL with PDVC has been designed based on a 1.8V $0.18{\mu}m$ CMOS process and proved by HSPICE simulation.

Purpose: There are no detailed reports on the incidence of venous thromboembolism (VTE) in pelvic and acetabular fractures in the Asian population. The purpose of this study was to investigate the incidence of VTE in pelvic and acetabular fractures in the Korean population. Methods: The cases of 67 Korean patients with pelvic and acetabular fractures treated at our hospital from January 2009 to February 2012 were analyzed retrospectively. Until May 2010, VTE screening was performed by contrast-enhanced computed tomography (CT) or ultrasonography (US) when the D-dimer value did not decline predictably, still exceeded $20{\mu}g/ml$ at 5 days after trauma and surgery, or increased to greater than $20{\mu}g/ml$ after a period of decline. After May 2010, contrast-enhanced CT and US were performed routinely irrespective of the D-dimer value. Physical prophylaxis was performed on all patients. The effects of the presence of a pelvic and/or acetabular fracture, and the effects of fracture type, accompanying injuries, and screening strategies on the incidences of VTE were investigated. Results: Overall, 26 patients(38.8%) were diagnosed with VTE and PTE in 14(20.9%). All were asymptomatic. Significantly higher incidences of VTE and PTE were observed in trauma patients with pelvic and acetabular fractures than in trauma patients without pelvic and acetabula fractures treated during the same period. No significant differences were observed in the incidences of VTE and PTE between patients with pelvic fractures, and patients with acetabular fractures or between patients with and without accompanying injuries. Compared with the previous screening strategy, the detection rates for VTE and PTE were higher for the newer screening strategy; however, the difference did not reach statistical significance. Conclusion: In the Korean population, we should be vigilant for a high incidence of VTE, especially PTE, in patients with pelvic and acetabular fractures.

한국 영어교과교육의 발전 방안으로서의 연구 종합

이상기(Lee, Sang-Ki) 한국영어교과교육학회 2010 영어교과교육 Vol.9 No.3

English education in Korea began more than 100 years ago and has evolved into a dynamic area of inquiry. It is indeed an appropriate time to conduct a comprehensive and rigorous review of the history of English teaching/learning practices in the Korean context. This systematic overview is important because it enables us to better understand what we have done in the past and what we should do in the future, and is possible through research synthesis and meta-analysis. This paper discusses three defining features of research synthesis and illustrates its step-by-step procedures, with a particular focus on meta-analysis. Several suggestions are also made for primary researchers, including: 1) the need to report basic descriptive statistics as well as standardized effect sizes and confidence intervals; 2) the possibility of conducting research synthesis in scholarly activities for theses and dissertations; and 3) the importance of acting and thinking synthetically in the academic environment.

A rapid and sensitive method for the determination of glyphosate, a phosphates amino acid herbicide, in whole blood is presented. After removal of protein, the whole blood was purified by using the anion exchange resin (Dowex 1), and derivatized with 9- fluorenylmethyl chloroformate (FMCL). Derivatized glyphosate from blood sample was injected onto a Whatman partisil 10SAX column and separated with 0.1M phosphate buffer (pH 2.5) and acetonitrile (ratio=3:1). The high performance liquid chromatography- fluorescence detection gave the detection limit of 86pg and linearity of 0.9999 in the range of 0.25μg/ml and 25μg/ml. The recoveries of glyphosate added to the blood samples were ranged from 75.3% to 100.4% compared to the samples prepared in water. The derivatized glyphosate was stable at various acidity and temperature. This method has been successfully applied to the blood samples of lethal intoxication with the herbicide glyphosate.

유아 영어교육에 대한 높은 사회적 관심을 반영하듯, 오늘날 거의 모든 유아교육기관에서 영어교육이 이루어지고 있다. 유아 영어교육 프로그램의 개발과 효과에 관한 논의가 절실한 시점에서, 본 연구는 사전-사후 연구 설계를 통해 동화와 동요를 활용한 주제중심 통합영어교육의 효과를 살펴보고자 하였다. 이러한 목적으로, 10개월의 연구기간 동안 경기도 성남시 소재 N 직장 어린이집의 만 4세 아동 12명을 대상으로 사전-사후 검사 및 수업관찰을 실시하였다. 연구 결과, 말하기, 듣기, 쓰기 영역에서 통계적으로 유의미한 학습 효과가 나타났고, 영어에 대한 흥미도가 통계적으로 유의미한 수준으로 증가하였다. 보다 자세한 연구 결과와 함께 후속 연구에의 시사점을 제안하였다. There has been a growing interest in English education for young learners and it is reported that English is being taught in almost every institution. This study aimed to empirically investigate the effects of a song and story-based and theme-centered integrated English program by employing the pre- and post-test design. To this end, 12 4-year-olds attending at N Daycare Center were pre- and post-tested and their English classes were observed over a 10-month period. The results showed that the performance of the children participants improved statistically significantly over the study period, especially in terms of speaking, listening, and writing. When it comes to their attitudes toward English, it was found that their interest level had increased significantly. More detailed findings are presented, together with some implications for future research.
