곽은선,곽재우,박명준 융복합지식학회 2023 융복합지식학회논문지 Vol.11 No.1

This study was conducted to understand salespersons’ attitudes toward and intention to use e-detailing devices and verify the validity and reliability of management accounting measurements. We used the survey tool to analyze and measure the relationship between perceived usefulness and ease of use and salespersons’ attitudes toward and intention to use e-detailing devices through their use of laptops and Tablet PCs. In addition, this study aims to help salespersons actively utilize e-detailing by investigating the factors affecting the attitudes and intention to use the devices in the subjects who would utilize e-detailing devices. So, as a new marketing channel in the actual business scene, we have investigated their attitudes and intention to use them based on the previous experience of salespersons’ use of laptops and Tablet PCs. This study analyzed the reliability and validity and of management accounting measurements regarding the reason why the introduction of e-detailing is in its early stage at domestic pharmaceutical companies. Especially, there were many more female respondents in Pfizer South Korea and many more young male respondents, in Hanmi Pharm. Next, as for the research method, direct rotation was performed to secure the independence of factors in performing factor analysis to confirm the validity of perceived ease and usefulness and other key conceptual variables, and factor loading was based on 0.5. Therefore, it was judged by classifying it into measurement items that explain each concept. As a result of the study, both laptop and tablet PCs showed consistent results in which the perceived ease and usefulness were divided into two factors, respectively, and the other variables, the intention to use, the individual's technology acceptance, and the organizational innovation variable, were composed of a single factor. appeared to be In addition, in the reliability analysis of measurement variables, Cronbach's Alpha coefficient, which calculates internal consistency, was used, and when the standardized alpha coefficient was 0.7 or higher, the internal consistency of the measurement tool was judged to be excellent. As a result of the reliability analysis of the measurement variables, the alpha coefficient of the main conceptual variable was in the range of 0.78 to 0.94, so it was confirmed that the measurement tool used in this study had high internal consistency.Finally, since the survey was conducted, not considering the pharmaceutical company’s characteristics like sex composition, which might cause a problem, it would be necessary to improve and supplement these limitations of the research method to induce the salespersons to actively participate in e-detailing. Thus, this study will be able to help the successful settlement of e-detailing by understanding why pharmaceutical salespersons do not actively use the management accounting measurements existing e-detailing devices and prepare improvements for that and contribute to the enhancement of efficiency and effectiveness. 본 연구는 영업사원의 e-디테일링 기기에 대한 태도와 사용의도를 파악하고 관리회계 측정의 타당성과 신뢰성을 검증하기 위해 수행되었다. 설문조사 도구를 사용하여 랩톱 및 태블릿 PC 사용을 통해 인지된 유용성 및 사용 용이성과 e-디테일링 장치에 대한 영업사원의 태도 및 사용 의도 사이의 관계를 분석하고 측정하였다. 또한 본 연구는 e-디테일링 기기를 활용하고자 하는 피험자들을 대상으로 기기 사용의도 및 태도에 영향을 미치는 요인을 조사하여 영업사원이 e-디테일링을 적극적으로 활용할 수 있도록 하는데 목적이 있다. 이에 기존 영업사원의 노트북 및 Tablet PC 사용 경험을 바탕으로 실제 비즈니스 현장에서의 새로운 마케팅 채널로, 이들의 태도와 사용의도를 조사하였다. 본 연구는 국내 제약회사에서 e-detailing 도입 초기인 이유에 대해 관리회계 측정의 신뢰도와 타당도를 분석하였다.특히 한국화이자에서는 여성 응답자가 많았고, 한미약품에서는 젊은 남성 응답자가 많았다. 다음으로 연구방법은 인지된 용이성 및 유용성, 그리고 기타 주요 개념변수들의 타당도 확인을 위하여 요인분석을 수행함에 있어서 요인들의 독립성 확보를 위하여 직교회전을 실시하였고, 요인적재량(factor loading)은 0.5를 기준으로 하여 각 개념을 설명하는 측정항목들로 분류하여 판단하였다. 연구결과 노트북과 태블릿PC 모두 인지된 용이성 및 유용성이 각각 두 가지 요인으로 구분되는 일관성 있는 결과를 보였고, 그 외 변수인 사용의도, 개인의 기술수용성 및 조직의 혁신성 변수는 단일 요인으로 구성되는 것으로 나타났다. 그리고 측정변수들의 신뢰성 분석에 있어서는 내적일관성(internal consistency)를 산출하는 크론바흐 알파(Cronbach’s Alpha) 계수를 활용하였고, 표준화 알파계수가 0.7 이상이면 측정 도구의 내적 일관성이 우수한 것으로 판단하였다. 측정변수들의 신뢰성 분석 결과로 주요 개념변수의 알파계수가 0.78~0.94 범위에 있으므로 본 연구에서 사용한 측정도구는 내적일관성이 높은 것으로 확인할 수 있었다. 끝으로 문제가 될 수 있는 성구성 등 제약회사의 특성을 고려하지 않고 설문조사를 실시하였으므로, 영업사원이 e-detailing에 적극적으로 참여하도록 유도하기 위해서는 이러한 조사방법의 한계점을 개선·보완할 필요가 있을 것이다. 따라서 본 연구는 제약영업사원들이 기존 e-detailing 기기의 관리회계 측정을 적극적으로 활용하지 못하는 이유를 파악하고 이에 대한 개선방안을 마련하여 효율성 및 효과성 제고에 기여함으로써 e-detailing의 성공적인 정착에 도움을 줄 수 있을 것이다.

현행 선거여론조사 방법의 정확성과 선거결과 예측 가능성

곽은선,김영원 한국조사연구학회 2022 조사연구 Vol.23 No.1

In this study, the accuracy of the election poll method currently being conducted in Korea based on the mobile phone virtual number was examined. The accuracy of the 2020 National Assembly election poll conducted after the introduction of the mobile phone virtual number system was investigated to see how much it improved in terms of accuracy through the current election poll using mobile phone virtual numbers. As a result of the analysis, it was confirmed that the accuracy of telephone public opinion surveys using mobile phone virtual numbers has improved significantly compared to the past. In addition, whether it is possible to use the current telephone poll for predicting the election results was investigated based on the case of a telephone poll conducted in Seoul and Busan ahead of the 4.7 by-election in 2021. We found that it was possible to accurately predict the vote rate for each candidate through correction of the response reserved group based on the logistic regression model. 본 연구에서는 2017년에 새로 도입되어 현재 국내에서 수행되고 있는, 휴대전화 가상번호를 근간으로 하는 선거여론조사 방법의 정확성을 두 가지 측면에서 살펴보았다. 먼저 휴대전화 가상번호를 활용한 선거여론조사 방법론의 개선을 통해 여론조사의 정확성이 어느 정도 향상되었는지 보기 위해, 2016년 국회의원선거 여론조사와 휴대전화 가상번호 제도 도입 후에 실시된 2020년 국회의원선거 여론조사의 정확성을 수도권에서 실시된 여론조사를 대상으로 비교‧분석하였다. 분석의 결과, 휴대전화 가상번호 도입 이후 전화여론조사의 정확성이 과거에 비해 대폭 향상되었다는 것을 확인할 수 있었다. 아울러, 가상번호를 기반으로 한 선거여론조사를 선거결과 예측 용도로 활용하는 것이 가능한지를 검증하기 위해 2021년 4.7 보궐선거를 앞두고 서울과 부산에서 수행한 방송사공동예측조사위원회 전화여론조사 사례를 토대로 분석하였다. 분석 결과 단순한 형식의 로지스틱 회귀모형을 기반으로 한 응답유보층에 대한 보정을 통해서도 상당히 정확한 후보자별 최종 득표율 예측이 가능하다는 결과를 얻었다.

An inclusion complex of muscone with ${\beta}-cyclodextrin$ (CD), as a solid form of muscone, was prepared to increase the solubility of muscone. The molar ratio of muscone to ${\beta}-CD$ in complex was in the range of $1:1{\sim}1:5$ when prepared by freeze-drying method. The interaction of muscone with ${\beta}-CD$ in solid state was investigated by Infrared (IR) spectroscopy and differential scanning calorimetry (DSC). IR and DSC studies between $muscone-{\beta}-CD$ inclusion complex and physical mixture showed that $muscone-{\beta}-CD$ inclusion complex was prepared stably. From the amount of muscone incorporated in the inclusion complex, it was found that the molar ratio of muscone : ${\beta}-CD$ was 1:1. Relative spatial position of muscone and ${\beta}-CD$ was observed by Hyperchem molecular modelling program.

Medical Representatives’ Intention to Use Information Technology in Pharmaceutical Marketing

곽은선,장혜정 대한의료정보학회 2016 Healthcare Informatics Research Vol.22 No.4

Objectives: Electronic detailing (e-detailing), the use of electronic devices to facilitate sales presentations to physicians, has been adopted and expanded in the pharmaceutical industry. To maximize the potential outcome of e-detailing, it is important to understand medical representatives (MRs)’ behavior and attitude to e-detailing. This study investigates how information technology devices such as laptop computers and tablet PCs are utilized in pharmaceutical marketing, and it analyzes the factors influencing MRs’ intention to use devices. Methods: This study has adopted and modified the theory of Roger’s diffusion of innovation model and the technology acceptance model. To test the model empirically, a questionnaire survey was conducted with 221 MRs who were working in three multinational or eleven domestic pharmaceutical companies in Korea. Results: Overall, 28% and 35% of MRs experienced using laptop computers and tablet PCs in pharmaceutical marketing, respectively. However, the rates were different across different groups of MRs, categorized by age, education level, position, and career. The results showed that MRs’ intention to use information technology devices was significantly influenced by perceived usefulness in general. Perceived ease of use, organizational and individual innovativeness, and several MR characteristics were also found to have significant impacts. Conclusions: This study provides timely information about e-detailing devices to marketing managers and policy makers in the pharmaceutical industry for successful marketing strategy development by understanding the needs of MRs’ intention to use information technology. Further in-depth study should be conducted to understand obstacles and limitations and to improve the strategies for better marketing tools.

The study aims to figure out what effect the language intervention activity with multimedia fairy tales has on the communication behavior and comprehension of children with intellectual disabilities. Three children with intellectual disabilities from the kindergarten for children with intellectual disabilities in G city, Gyeongsangbuk-do Province participated in the study as subjects, and the multiple-probe design was employed. Total 23 fairy tales were used for the experiments; the language intervention activities started after the children completed watching the multimedia fairy tales; during the activities, the children were asked to look at the pictures of the fairy tales. Additionally, the conversation provoking questions were given to them in order to observe and measure their comprehension and communication behavior. The outcomes are as follows. First, the language intervention activity based on multimedia fairy tales showed a positive impact on the children’s communication behavior; it helped the children with intellectual disabilities to improve, maintain their communication behavior and increase the verbal expression. Second, the language intervention activity based on multimedia fairy tales showed a positive impact on the children’s comprehension of the stories; the children showed better comprehension of the questions and improved expressions for stories. This implies that the language intervention activity based on multimedia fairy tales is an effective way of improving the communication behavior and comprehension of the children with intellectual disabilities. To increase the children’s ability(comprehension the stories and communication with others), it is necessary to conduct the generalization under a natural condition; and various intervention methods are required for the children to increase their abilities of using an important tool of communication, the verbal expression. Lastly, involving the family members of the children is also important to study the way of delivering the multimedia fairy tales in a more positive way. 본 연구는 멀티미디어 동화를 활용한 언어중재활동이 지적장애아동의 의사소통 행동과 이야기 이해력에 미치는 영향을 알아보는데 목적이 있다. 연구대상자는 장애전담어린이집에 재원중인 지적장애아동 3명이며, 대상자간 중다 간헐 기초선 설계를 사용하여 연구를 진행하였다. 본 연구에서는 멀티미디어 동화 그림 자료를 활용한 언어중재활동을 실시한 후, 의사소통 행동과 이야기 이해력을 관찰 및 측정하였으며 다음과 같은 연구결과가 도출되었다. 첫째, 멀티미디어 동화를 활용한 언어중재활동은 지적장애아동의 의사소통 행동은 증가 및 유지되는 긍정적인 영향을 미쳤다. 둘째, 멀티미디어 동화를 활용한 언어중재활동은 지적장애아동의 이야기 이해력을 향상시켰으며, 질문에 대한 이해와 이해한 내용에 대한 표현 향상에 긍정적인 영향을 미쳤다.

곽은선 ( Eun Sun Kwak ),김지연 ( Ji Yeon Kim ),김영원 ( Young Won Kim ) 한국조사연구학회 2013 조사연구 Vol.14 No.3

본 연구에서는 출구조사 예측오차의 발생 원인과 특성을 알아보기 위해 2012년에 치른 19대 총선 출구조사의 자료를 이용하여 출구조사 예측오차를 분석하였다. 예측오차를 정리해 본 결과 새누리당에 대해서는 과소 예측이, 통합야당에 대해서는 과대예측이 발생했으며, 시·도별로 편향 수준에 차이가 있었다. 예측오차를 투표소추출 오차와 실사오차로 구분해 보면 투표소추출오차에 비해 실사오차가 더 심각하였다. 또한 오차를 발생시킬 것으로 예상되는 변인들과 투표소추출오차 및 실사오차와의 상관분석을 통해 조사거절률이 실사오차에 유의한 양의 상관관계를 갖고 있으며, 표본추출률을 증가시키면 투표소추출오차가 감소한다는 사실도 확인할 수 있었다. 한편출구조사를 진행한 세 개 조사기관별로 오차를 비교해 본 결과 특히 실사오차에 있어서 조사기관간의 차이가 통계적으로 유의한 것으로 나타났다. In this study, we investigate the data of the exit poll for the 19th general election of 2012 to analyze the causes and characteristics of exit poll forecasting error. The empirical studies show that systematic negative bias of candidates affiliated to Saenuri Party is serious in the specific regions. To explore the main causes and effects of the forecasting error, the total survey error is divided by sampling error of the polling sites and non-sampling error which comes from selecting voter and collecting responses from sampled voters in each polling sites. And we consider relationships among several factors, which are anticipated as main causes of error, and non-sampling error as well as sampling error. As a result of correlation analysis, we can figure out that the nonsampling error of the exit poll mainly come from non-response. Also we consider the house effect in exit poll.
