This study sought to analyze how the severity of voice phishing affects the general public's preference for integrated reporting and response to voice phishing, and furthermore, to analyze whether voice phishing response methods moderate the relationship between them. To this end, this study analyzed it with a multiple regression model including an interaction term using data from the 'Public Opinion Survey on the Launch of the Government Joint Investigation Team for Voice Phishing Crime.' As a result of the analysis, the perception of the seriousness of voice phishing had a positive effect on the preference for integrated reporting and response to voice phishing. Among the response methods, the standard categories of 'report to the National Police Agency, etc.' were shown to be more preferred in the case of 'non-response', 'reconfirmation to impersonation agencies, etc.', and 'other'. Integrated reporting and response to voice phishing was preferred. The interaction term between response method and 'non-response', 'reconfirmation with imposter organizations, etc.', and 'other' showed a significant negative effect, weakening the relationship between voice phishing seriousness awareness and voice phishing integrated reporting/response preference lecture. This study found that there is a need to emphasize the seriousness of voice phishing through education and promotional campaigns, and that a one-stop method such as an integrated reporting and response center is important, but it is also important to provide easy and convenient access for the general public.

A Status Analysis of Middle School Students' Preference for Science

Yoon, Jin 한국과학교육학회 2002 한국과학교육학회지 Vol.22 No.5

The purpose of this research was to survey middle school students' preference for science and its causal factors, so as to analyze the causal relationships between them. Preference for science and its causal factors were defined theoretically, and a theoretical model was constructed to measure them and analyze the causal relationship by structural equation modeling. According to the theoretical model and a pilot test, a questionnaire was developed with three parts; the background information of a respondent, the preference for science, and the causal factors of preference. The questionnaire was administered to one class per grade of randomly selected 8 middle schools from 4 areas across the country, and 819 students' data were collected. Preference for science was defined as a state of mind. It revealed to what extent, and how, one likes science. It consisted of 3 categories - 'emotional response', 'behavioral volition', valuational comprehension', and each category was divided into two subcategories. Causal factors affecting the preference for science consisted of three categories - personal, educational and social factors, and each was divided int 2 or 3 subcategories. Middle school students' preference for science was middling as a total. Curiosity about contents of science and valuation of science were high, comparatively, but behavioral volition about science was especially low. Students' responses to the causal factors were relatively high in every educational factor and sociocultural valuation of social factors, but relatively low in socioeconomic rewards of social factors, and especially low in personal factors. The causal relationship about the preference for science was investigated by multiple regression analysis and path analysis, using the structural equation model. Multiple regression analysis about the preference for science and its causal factors revealed important factors. The important factors were personal ability, the personal traits, rewards in school science, and contents of school science in order of magnitude of standardized regression coefficient β. Stepwise regression analysis with each of the subcategories of the preference for science as dependent variables showed what factors were important in each subcategory. According to the result of structural equation modeling, personal factors affected 'emotional response' and 'behavioral volition' directly, and social factors affected 'valuational comprehension' directly. Educational factors affected all categories of the preference for science by influencing not only 'emotional response' and 'valuational comprehension' directly, but also ' behavioral volition' indirectly. The way to promote middle school students' preference for science was suggested, based on the analysis result.

An Analysis of Response Utterances Found in Colloquial Discourse of Marriage Woman Immigrants. Bilingual Research 51, 1-25. The purpose of this paper is to analyze the response utterances that can measure the interactivity of conversation from the colloquial discourse of marriage woman immigrants and to provide basic data about the aspect of the use of Korean as a second language. The participants were 25 marriage woman immigrants with elementary level of Korean speaking ability who were from China, Cambodia, Vietnam, the Philippines, Uzbekistan, and Peru. Through the spoken corpus of the participants` daily conversation, the response utterances which are adjacency pairs of questions were divided into the preferred response and the dispreferred response. And the aspects of use by function and by form were examined. The research results showed that the elementary level marriage woman immigrants used lots of simple responses intensively that provide only direct information in the response utterances. This means that they are not skilful in mutually cooperative conversation when speaking in Korean and have a hard time composing the response utterances in appropriate Korean. Accordingly, in order for them to communicate naturally in Korean, the development of concrete educational methods of the response utterances suitable to Korean circumstances and forms in Korean language training is required.

쌍대반응표면최적화를 위한 사후선호도반영법: TOPSIS를 활용한 최고선호해 선택

정인준 한국지식경영학회 2018 지식경영연구 Vol.19 No.2

Response surface methodology (RSM) is one of popular tools to support a systematic improvement of quality of design in the product and process development stages. It consists of statistical modeling and optimization tools. RSM can be viewed as a knowledge management tool in that it systemizes knowledge about a manufacturing process through a big data analysis on products and processes. The conventional RSM aims to optimize the mean of a response, whereas dual-response surface optimization (DRSO), a special case of RSM, considers not only the mean of a response but also its variability or standard deviation for optimization. Recently, a posterior preference articulation approach receives attention in the DRSO literature. The posterior approach first seeks all (or most) of the nondominated solutions with no articulation of a decision maker (DM)’s preference. The DM then selects the best one from the set of nondominated solutions a posteriori. This method has a strength that the DM can understand the tradeoff between the mean and standard deviation well by looking around the nondominated solutions. A posterior method has been proposed for DRSO. It employs an interval selection strategy for the selection step. This strategy has a limitation increasing inefficiency and complexity due to too many iterations when handling a great number (e.g., thousands ~ tens of thousands) of nondominated solutions. In this paper, a TOPSIS-based method is proposed to support a simple and efficient selection of the most preferred solution. The proposed method is illustrated through a typical DRSO problem and compared with the existing posterior method.

김명희,김정선 한국어문교육연구회 2009 어문연구(語文硏究) Vol.37 No.3

본 硏究에서는 32個月-43個月 兒童 4명을 대상으로 幼兒의 質問 話行에 대한 應對 方法을 縱的으로 살펴보았다. 質問에 대한 應對를 選好的 應對와 非選好的 應對로 하위 구분하여 구체적인 출현 양상을 분석한 후, 先行 質問의 유형에 따른 應對 方法을 살펴보았다. 분석 결과는 다음과 같다. 1) 選好的 應對는 單純 應對와 擴張 應對로 하위 구분할 수 있는데, 幼兒에게서는 成人에 비해 월등히 높은 비율로 單純 應對가 우세하게 나타났다. 擴張 應對는 添加的 擴張이 높게 나타났다. 2) 非選好的 應對는 遂行的 관점의 應對가 높게 나타났으며, 應對 回避의 출현 비율이 높았다. 成人은 應對 回避를 할 경우 對話 진행 방해나 대인 관계 갈등이 유발되어 기피하는 반면에, 유아는 응대 회피가 지닌 이러한 속성을 인식하지 못하고 수행하는 것으로 나타났다. 3) 先行 質問의 유형에 따라서는 說明 質問에 대한 應對에서 非選好的 應對가 높게 나타났다. The purpose of this study is to conduct a longitudinal research on methods of responses to question speech acts of early childhood. The subjects were four early childhood between 32 and 43 months old. The responses to questions were sub-divided for analyzing the specific modes of occurrence, and methods of responses according to the types of precedent questions were also identified. The results of the analysis are as follows. First, the responses to questions were divided into preferred and non- preferred responses. The preferred responses were sub-divided into simple and extended responses, and the simple responses were dominant in early childhood with remarkably higher frequency when compared to those of adults. Out of the extended responses, additional extension was highly shown. Second, out of the non-preferred responses, responses of performing aspect were highly shown, and response avoidance was frequent. While adults evade response avoidance because it can induce communication disturbance or struggles in interpersonal relationships, the early childhood were shown to perform it as they could not recognize its attributes. Also in the non-preferred responses at information level, the early childhood performed them due to lack of competence or world knowledge, showing difference from adults. Third, as for the types of precedent questions, non-preferred responses were highly shown in responses to wh-questions.

Color preference can be affected by various factors which can have some effects on cognitive responses since it is the product of cognitive response to either like or dislike. Therefore, this researcher analyzes how the recollection process that occurs at the period when the color preference is examined influences some characteristics of color preference, in order to investigate the characteristics of color preference appearing in the cognitive process. To this end, an experiment is conducted by dividing the types of recollection into recollections for preferred and hated colors. The findings are as follow. The process of recollection for a specific color is capable of modifying subjects" preferred and hated colors as well as the degree of preference of the subject selected. Moreover, the degree of change in the future preference is also varied according to the type of recollection, and the group which recollects both preferred and hated colors shows a larger degree of change in the preference compared to other groups which recollect either of them. Thus, it is verified that if the same subject is stimulated by a specific color which influences his cognitive process, the color preference may change in the future. There is a need for a new approach rather than the existing fragmented research on the color preference, in that it should be understood based on characteristics of the cognitive response.

김명준 ( Myungjoon Kim ),강새하늘 ( Saehaneul Kang ),남한 ( Han Nam ) 한국심리유형학회 2021 심리유형과 인간발달 Vol.22 No.2

본 연구는 MBTI에 관심을 지닌 연구자들 및 MBTI 사용자들을 위하여 이들 두 채점체계의 특징을 비교·소개하고자 하는 목적으로 수행되었다. MBTI Form M은 두 가지 채점 방식을 가지고 있다. 즉 문항반응이론(IRT)에 기반한 컴퓨터 채점과 단일 배점 방식에 기반한 자가채점 방식이다. 구체적 연구내용으로 첫째, 자가채점 방식의 일반적 특징과 선호문자 산출 과정을 기술하고 해당 방식으로 산출한 문항의 양호도와 검사의 신뢰도를 확인하였다. 둘째, 컴퓨터채점 방식의 일반적 특징과 선호문자 산출 과정을 기술하고 해당 방식으로 산출한 문항의 양호도와 검사의 신뢰도를 확인하였다. 특히 MBTI 사용자 및 연구자에게 생소할 수 있는 문항반응이론을 컴퓨터채점 방식에 적용하고 해석하는 방법을 자세히 기술하였다. 셋째, 두 채점체계로 산출한 선호문자의 일치율을 계산하여 지표별 선호를 구분하는 가장 정확한 중간점을 기술하였다. 이와 같은 연구를 위하여 2012년부터 2020년까지 어세스타에 누적된 자료 중 대한민국 인구 분포와 맞게 비례층화 방식으로 표집한 19,070명을 분석에 사용하였다. 주요연구 결과는 다음과 같다. 첫째, 문항의 양호도를 나타내는 자가채점 방식의 선호문자 예언율이 E, I, S, T, J 문자에서 Form G와 비교해 개선된 것으로 나타났으며, 4개 지표의 문항내적합치도 또한 .90 수준으로 나타났다. 둘째, 문항반응이론으로 산출한 3모수를 통해 문항의 양호도를 확인한 결과 변별도 기준으로는 E-I 지표가, 난이도 기준으로는 E-I, S-N 지표가, 추측도 기준으로는 E-I, T-F 지표가 매우 좋은 수준으로 나타났다. 추가로 문항반응이론에서 신뢰도를 의미하는 검사정보함수를 그래프로 산출한 결과 선호도 추정치인 세타(θ)의 중간점 부근에서 가장 많은 정보를 포함하여 선호도가 뚜렷하지 않은 사람들의 유형을 정확히 분류해주는 것으로 나타났다. 셋째, 자가채점과 컴퓨터채점의 선호문자를 비교한 선호지표별 일치율은 96.3%~98.1%로 나타났으며, 자가채점 지표별 문항의 절반을 기준으로 선호지표를 결정할 때 일치율이 가장 높았다. 마지막으로 두 채점절차의 차이로 인해 발생하는 선호문자의 불일치는 대부분 중간범위에서 발생되는 것을 확인하였다. 끝으로 본 연구의 의의와 후속연구 제언을 구분하여 논의하였다. There are two scoring methods in MBTI Form M. One is Item Response Theory (IRT)-based computer scoring method, and the other one is unit-weight based self-scoring method. This study introduces and compares the unique characteristics of those two different scoring methods and summarizes the findings for MBTI users and researchers. In this study, there are three main contributions. First, authors addressed the aspects of self-scoring method and the process of obtaining preference types, and then examined the quality of items. Additionally, the overall reliability of assessment was described. Second, the characteristics of computer scoring method and the process of obtaining preference type were discussed, and the item’s quality and reliability of the assessment were examined. In particular, authors elaborated the details of IRT application to MBTI scoring for audiences, including MBTI users and researchers. Lastly, the preference types’ concordance rate from the two scoring methods was calculated to see the most accurate middle point, which identifies the preference indicator. In total, 19,070 samples were used in this study. The samples were collected from Assesta’s server that contained archived data from 2012 to 2020, and proportional stratified sampling method was used to obtain the final samples. There are three main findings in this study. First, the predictive rate was advanced from E, I, S, T, and J indicators. The predictive rate of preference type (self-scoring method) is an indicator of item’s quality, which was improved in comparison with the same rate from Form G. Additionally, internal consistency of four indicators were found to be .90 or above. Second, each item’s quality was examined by using three parameters from IRT model. Specifically, in terms of the good item indices, item discrimination index was good in E-I indicator, item difficulty index was good in E-I and S-N indicators, and item guessing index was good in E-I and T-F indicators. In addition, test information function, which is the indicator of reliability in IRT, was computed with a graph. The result showed that the majority of information was found near the middle point of theta (θ; preference estimate), which helps in identifying people who do not have a clear preference. Third, the preference type’s concordance rate was 96.3~98.1%, which was compared with the preference results from the computer and self-scoring methods, and the concordance rate was highest when people decided their preference types in the middle of self-scoring items. Lastly, the inconsistencies of preference types due to the differences of two scoring methods was mostly found in the middle range. At the end, the implications of this study and the future research directions were discussed.

호출형 차량공유 서비스에 대한 고령자 선호도 연구

김원철 한국도로학회 2018 한국도로학회논문집 Vol.20 No.6

PURPOSES: The purpose of this study is to analyze the elderly's preference for ride hailing (car sharing) services that use non-commercial vehicles and to identify the crucial factors influencing this preference. METHODS : Based on a literature review, a questionnaire was made to explore the preference of the elderly (over 65 years old) for ride hailing services. The survey was conducted in a rural area in Chungcheongnam-do. A total of 210 completed questionnaires were obtained. A binary probit model was applied to estimate the preference choice behavior. RESULTS: Monthly income, gender, age, and the time it takes to walk to the nearest bus stop were the main factors that influenced the preference for ride hailing services. The preference for ride hailing is likely to decrease when the monthly income of the elderly increase, and increase when the nearest bus stop is far away or as people get older. In addition, women had a stronger preference for ride hailing than men. CONCLUSIONS : For the elderly, ride hailing services can help them maintain their mobility and could be one of the countermeasures for demand-responsive transport from a sustainable perspective.

다중반응표면 최적화에서 가중평균제곱오차 최소화법을 위한 선호도사후제시법

정인준(Jeong, In-Jun) 한국산학기술학회 2015 한국산학기술학회논문지 Vol.16 No.10

다중반응표면 최적화는 다수의 반응변수(품질특성치)를 동시에 고려하여 최적의 입력변수 조건을 찾는 반응표면분석 의 세부 분야이다. 가중평균제곱오차(Weighted Mean Squared Error, WMSE) 최소화법은 평균제곱오차의 두 구성 요소인 제 곱편차와 분산에 가중치를 부여한 WMSE를 활용하는데, 반응변수별로 WMSE를 구하여 이들을 종합적으로 최소화한다. 지 금까지 WMSE 최소화법과 관련하여 개발된 기법은 대부분 의사결정자의 선호도 정보를 문제풀이 이전에 결정할 것을 요구 하는 선호도사전제시법에 해당된다. 그러나 현실적으로 의사결정자가 자신의 선호도 정보를 사전에 정확히 제공하는 것은 매우 어렵다. 본 논문에서는 이러한 한계점을 개선하기 위하여 WMSE 최소화를 위한 선호도사후제시법을 제안한다. 제안된 방법은 의사결정자의 선호도 정보 없이 다수의 비지배적해를 생성한 후, 의사결정자가 생성된 비지배해 중 최고선호해를 선택하는 단계로 진행된다. 제안된 방법은 의사결정자로 하여금 전체 해집합의 트레이드오프 관계를 보다 폭넓은 시각으로 이해한 후 선호도 정보를 제시할 수 있도록 함으로써, 의사결정자의 선호도에 부합하는 최고선호해를 효과적으로 도출할 수 있다. Multi-Response Surface Optimization aims at finding the optimal setting of input variables considering multiple responses simultaneously. The Weighted Mean Squared Error (WMSE) minimization approach, which imposes a different weight on the two components of mean squared error, squared bias and variance, first obtains WMSE for each response and then minimizes all the WMSEs at once. Most of the methods proposed for the WMSE minimization approach to date are classified into the prior preference articulation approach, which requires that a decision maker (DM) provides his/her preference information a priori. However, it is quite difficult for the DM to provide such information in advance, because he/she cannot experience the relationships or conflicts among the responses. To overcome this limitation, this paper proposes a posterior preference articulation method to the WMSE minimization approach. The proposed method first generates all (or most) of the nondominated solutions without the DM’s preference information. Then, the DM selects the best one from the set of nondominated solutions a posteriori. Its advantage is that it provides an opportunity for the DM to understand the tradeoffs in the entire set of nondominated solutions and effectively obtains the most preferred solution suitable for his/her preference structure.
