의료소비자의 인터넷 기반 의료정보서비스 이용행태와 병원선택: 인터넷 조사

정희태,김정아 대한의료정보학회 2005 Healthcare Informatics Research Vol.11 No.2

Objective: This study was designed to identify the usage patterns and perception of Internet-based medical information services and its effect on hospital selection. Methods: An Internet survey was conducted on a web-site between 10 and 25 June, 2004. A total of 600 surveys were administered, of which 409 were adequately completed and included in the study. The collected data were analyzed on SPSS 11.0. Frequency and percentile were calculated. Results: Among the survey respondents, almost 90% reported having access to Internet-based medical information services. The majority(66.3%) of respondents reported the reasons for accessing the Internet-based medical information services were treatment modalities of disease, promoting health, and acquiring general knowledge in health. Seventy-eight respondents reported that they visited the hospital which provided the Internet-based medical information services they had accessed. Conclusion: This study implies that Internet-based medical information services can be used in health service marketing.

System Dynamics Modeling for Policy Analysis of Occupational Injuries

정희태 한국디지털콘텐츠학회 2015 한국디지털콘텐츠학회논문지 Vol.16 No.3

The research of occupational injury for safety and health is a comparatively recent occurrence. As labor activities took place regarding to employee concerns in industrial uprising, human resources health was tried to enhanced as a labor safety subject. Noticing that traditional statistics approach has limitations in learning future forecasting and major factors causing occupational injuries in each industry, Korean Government initiated a quantitative systematic simulation model project to analyze how the annual injury rate has been dropped and stays in a level for recent years. From this motivation and the project, system dynamics models have been developed to explain the mechanisms for reducing annual injury rate, and the mechanisms quantitatively. The main cause effects for the reduction of annual injury rate were due to the government driven investment on safety facilities. In overall viewpoint the gain achievable from these efforts has been reached a saturated level. However, it could reduce the annual injury rate if you chose the industry and size carefully. The model for forecasting, major injury factors, safety budget and allocation are introduced and analyzed, and Analyzing occupational injury related factors can also reduce employee injury and disease related costs, including medical care, quit, and disability assistance costs.

농촌 지역에 의료기관인증병원 의료서비스가 고객만족서비스와 재방문 의사에 미치는 상관관계 연구

정희태 국제차세대융합기술학회 2020 차세대융합기술학회논문지 Vol.4 No.1

본 연구의 목적은 의료사각지대인 농촌지역에 거주하며 의료이용율이 빈번한 노인들이 “의료기관 인증제 도”를 실시한 의료기관과 실시하지 않은 의료기관 방문경험이 있는 노인을 대상으로 의료 소비자의 만족도 및 재 방문 여부를 통한 “의료기관 인증제도”의 효용성과 그 성과를 비교・조사함으로써, 의료소비자들의 의료기관 선택 기준 마련에 기초 자료를 제공하는데 그 목적이 있다. 이를 위해 S읍 소재 병원2곳의 방문자 200명을 대상으로 설문 전 ‘의료기관 인증제도’가 무엇인지에 대하여 간략히 설명을 덧붙여서 직접 알려주었으며 고객만족도와 재 방문의사로 구성된 구조화된 설문지를 사용하여 통계분석 하였다. 분석결과는 인증의료기관의 만족도는 그렇지 않 은 의료기관보다 유의하게 만족도와 재방문율이 더 높은 것으로 나타났다. 이 결과는 오늘날 의료는 의료서비스 양보다는 질적인 측면이 만족도를 높이는 요인으로 등장하였음을 확인하였고, 의료기관인증제도의 효용성과 공신 력을 제고하는 계기가 될 것이다. 따라서 본연구의 결과를 통하여 향후 의료기관이 의료서비스 질을 통한 신뢰도 향상을 위해 계속적인 노력에 박차를 가하는 계기가 될 것으로 사료된다. The purpose of this study was to evaluate the effectiveness of the "Medical Institution Certification System" through satisfaction and return visit for medical residents who visited the medical institutions that conducted the "Medical Institution Certification System" and residents living in rural areas, The purpose of this study is to provide basic data for the medical consumer selection criteria. For this purpose, statistical analysis was performed on 620 visitors from two S - eup hospital using structured questionnaire consisting of customer satisfaction and return visit. The results of the analysis showed that satisfaction of certified medical institutions was significantly higher than that of non - certified medical institutions. This result was confirmed by today's medical care service quality hayeoteum emerged as a key factor of competitive institutions, will be an opportunity to enhance the effectiveness and credibility of the medical certification system

학습동기와 충동성이 SPRT형 CAT에서의 자신감과 풀이시간 및 합격·불합격 판정에 미치는 영향

정희태 한국교육정보방송학회 2002 교육정보미디어연구 Vol.8 No.3

본 연구의 목적은 학습자의 심리적 특성(학습동기, 충동성)이 수험자의 정답반응에 대한 자신감 표출과 문제풀이에 시간을 소요하는 반응유형에 어떠한 영향을 미치는지, 그리고 그러한 반응유형이 SPRT형 CAT의 합격 불합격 판정에 어떠한 영향을 주는지 알아보는데 있다. 특히 본 연구는 CAT 평가 도중 개인의 인지적 심리적 특성을 저장해 둔 적응적 웹기반 데이터베이스를 참조하여 여기서 얻은 정보들을 CAT 판정 과정에서 활용할 수 있는 기술적 기반을 마련하여 향후 CAT가 개인의 인지적 심리적 특성에 따라 적응적인 평가시스템으로 발전되도록 하는 계기를 만들고자 하였다. 본 연구의 목적을 달성하기 위하여 부산시내 Y중학교 3학년 여학생 223명이 선정되었다. 이들을 대상으로 학습동기 검사와 충동성 검사를 실시한 후, 도덕과목에 대한 CAT 평가를 실시하여 자료를 수집하고 통계적으로 분석하여 다음과 같은 결과를 얻었다. 첫째, 합격자들은 불합격자들에 비해 문제풀이에 더 많은 시간을 사용하였고, 정답반응에 대해서도 보다 높은 자신감을 보였다. 한편, 정답반응에 대한 자신감 표현의 정도는 SPRT형 CAT에서의 합격 불합격 판정을 예언하는데 있어서 유의미한 예언변인이 될 수 있는 것으로 나타났으나, 문제풀이 소요시간에 대해서는 유의미한 결과를 얻지 못했다. 둘째, 합격자들은 불합격자들에 비해 학습동기가 높고 충동성이 낮으며, 정답반응에 대해 보다 강한 자신감을 표현할 뿐만 아니라 문제풀이에도 보다 많은 시간을 사용 하는 경향이 있었다. 셋째, 수험자의 학습동기와 충동성 수준은 모두 SPRT형 CAT의 합격 불합격판정에 대해 의미 있는 예언력을 갖는 것으로 밝혀졌다. 즉, 수험자의 학습 동기 수준이 높을수록, 그리고 충동성 수준이 낮을수록 합격할 확률이 불합격할 확률보다 더 높아진다는 사실이 밝혀졌다. The purpose of this study was to investigate the influences of the psychological factors, such as academic motivation and impulsiveness, on the examinee's confidence for his/her answer for each test item, the time taken to solve test items, and the master/non-master decision making process in SPRT(Sequential Probability Ratio Test)-typed CAT(Computer Adaptive Testing). To get the answers about the questions of this study, the data were collected from 223 middle school students in the 9th grade in Pusan, and were analyzed by using F-test, correspondence analysis, and logistic regression analysis. The results of this study are as follows: For the first issue: First, the extent of confidence for correct answer expressed by examinee was confirmed as the significant predictable variable to predict him/her as a master or non-master. But the time taken used by examinee to solve the test items was not confirmed as the significant one. For the second issue: First, there was not a significant difference in time taken to solve test items among the groups that had different level(high, mid, low) of academic motivation. But there was a significant difference in time taken to solve test items among the groups that had different level(high, mid, low) of impulsiveness. Second, masters had the higher level of motivation and lower level of impulsiveness, and had the tendency to express more stronger confidence for correct answer and consume more time to solve test items. For the third issue: Both of examinee's academic motivation and impulsiveness were confirmed as the significant predictable variable to predict him/her as a master or non-master. Thus, the higher academic motivation level and the lower impulsiveness level any examinee had, the higher probability he/she could be judged as a master was existed. From the results of this study, the following implications can be acquired. First, as the confidence for correct answer and time taken to solve test items that masters and non-masters shows while taking CAT is having a consistent and regular response patterns, so if we put such response patterns into the algorithm to judge any examinee as a master or non-master, it will be more useful to enhance the efficiency and correctiveness in SPRT-typed CAT. Second, before adding these response patterns to that kind of algorithm, we have to add another algorithm module to consider psychological traits influencing on these response patterns to reduce the decision error might be caused by the psychological variables such as academic motivation and impulsiveness. Third, according to the results of this study, we have to device various kind of motivational strategies to help examinee to display his/her cognitive ability sincerely and composedly with psychologically balanced mind in the process of CAT.
