지능형교통시스템(ITS) 구축 사업을 통해 수집된 소통정보, 대중교통정보 등의 교통관련 정보를 제공하기 위한 방법으로 교통정보 안내전화(ARS)를 적용하여 도로 이용자에게 교통정보를 제공하고 있다. 도로 이용자에게 보다 편리한 교통정보 서비스를 제공하기 위한 일환으로 교통정보 안내전화(ARS)에 음성인식을 적용하고 있다. 그러나 초기 ARS에 음성인식을 적용한 결과 음성인식 성공률은 상당히 높은 것으로 나타났으나, 이용자가 증가하여 샘플링 수가 증가함에 따라 음성 인식 성공률은 점차 저하되고 있는 실정이다. 이를 해결하기 위한 방안으로 충분한 샘플링을 확보하여 주기적이고 지속적인 음성인식에 대한 튜닝을 실시하여 음성인식에 대한 성공률을 향상 시킬 필요가 있다.

As firms increase their operations in the international arena, there is a growing need for managers to understand cross-cultural issues in adopting information systems(IS). The present study surveyed IS developers with respect to their perceptions on the importance of various criteria for successful development of information systems. The results indicated that developers perceive criteria related to the organizational and systems level to be more important than criteria on the strategic and user level. In addition, the developers perceive immediate/direct criteria as more important that indirect/long term criteria. The current study found little differences between developers working for innovative versus those working for non-innovative companies with respect to their views on the importance of various success criteria. There were also very little differences in the perceptions of IS developers at different hierarchical ranks.

The purpose of this study is to explore the multi-dimensionality and the differences of the career success that is revealed by the employee's perception. In order to fulfill the research purpose, LDA topic modeling has applied to extract latent topics of career success from 126 Korean employees' open-end survey questionnaires. The extracted latent topics are social recognition, continuing service within an organization, expertise, financial rewards, and pursuing personal meaning. The occurrence probability of each topic was different by individual characteristics such as gender, education, position. Study findings showed there is multi-dimensionality in career success, and there are differences of topic occurrence probability by demographic characteristics. Additionally, this study showed how to apply the recently developed machine learning approach in order to reduce the researcher's bias by adapting the LDA topic modeling to the qualitative open-ended survey data.

The purpose of this study is to look into how elderly people's health promoting behaviors influence their successful aging, to realize how their perception of successful aging and their life satisfaction have the mediating effect on the path from health promotion behaviors to successful aging, and to find the significant influence of successful aging perception and life satisfaction on successful aging. This researcher conducted a questionnaire survey with elderly people using a senior welfare center in Gyeonggio-do, and analyzed 250 copies that. For data analysis, SPSS Win 25 was applied to conduct frequency analysis, descriptive statistics, t-test, one-way ANOVA, and correlation analysis. Mediating effect analysis was made to verify the causal relations between health promoting behaviors and successful aging, and to validate the mediating effect of successful aging perception and life satisfaction on the causal relations. As a result, elderly people's health promoting behaviors influenced their perception of successful aging, their life satisfaction, and their successful aging. Their perception of successful aging had the mediating effect on health promotional behaviors and successful aging, but life satisfaction did not so. This study has the following implications: it is necessary to train persons specializing in support for health promoting, to develop an efficient health promotional model and program, and to provide an opportunity of education. It is necessary to come up with a support policy in consideration of tangible or intangible factors. It is necessary to establish a policy in line with economic levels and health conditions of elderly people.

프로젝트에서 리스크 관리란 프로젝트 진행 시 발생가능성이 있고, 프로젝트에 긍정적 또는 부정적 영향력을 가진 이슈를 미리 발굴하여, 효과적으로 관리하기 위한 기법이다. 이런 점에서 리스크 관리는 프로젝트 목적 달성 즉 성공을 위한 수단이며, 예기치 못한 사건에 대한 사후대책 보다는 사전대책의 특성을 가지고 있다. 이러한 리스크 관리에 대하여 건설, 금융, 국방, 공공 분야의 프로젝트에서는 그 중요성을 인식하여 다양한 분야의 연구가 활발히 진행 중이고 현장에서도 활용하고 있으나, 소프트웨어 개발 프로젝트에서는 아직 그 중요성에 대한 인식이 부족하고, 현장에서의 활용도 저조하다. 반면 소프트웨어 개발 프로젝트에 대한 고객의 요구사항(비용절감, 일정 단축, 품질 향상, 신기술 적용등)은 점점 복잡해지고, 정교해지고 있어 제한된 리소스로 개발을 진행해야 하는 프로젝트 팀 입장에서는 프로젝트 성공에 대한 부담감이 점점 증가하고 있다. 본 연구에서는 리스크 관리를 수행한 프로젝트와 그렇지 않은 프로젝트의 사례를 비교하여 리스크 관리가 프로젝트 성공에 미치는 영향에 대해 연구하였다.

The successful aging paradigm suggests that the elderly keep their social ties and actively participate in various activities in later life. Many Korean studies on aging, however, have overlooked the importance of various social activities and relationships beyond kinship. This article aims to investigate the perceived social activities among Korean elders to comprehend the subjectivity of successful aging. 613 respondents, over 50 years old, are selected from a national survey data which was collected by face-to-face interview based on the structured questionnaire. The respondents are classified into pre old (50-64), young old (65-74), old old (over 75). Major findings are as follows. The social activities are grouped into two sub-categories: 'relational activity' and 'productive activity'. The activity types are different by the age cohorts. Various activities are considered in terms of one's needs or motivations, and properly chosen based on the subjective evaluation during life course. Both demographic variables such as sex, area and social context variables such as marital status, living-together show influence on the activity type choices. Plans for later life and work ethics are important as well. Policies regarding social participation emphasizing productivity should positively consider relational motives, as perceived by the Korean elderly.

The purpose of this study was to compare gifted and non-gifted high school students on their perceptions of success, grit, aspirations, and achievement goal orientation. Of the 550 high school students surveyed from 4 high schools (i.e., two schools for gifted, two school for non-gifted) in three metropolitan cities, Korea, 496 (i.e., 153 gifted and 343 non-gifted) completed and returned the questionnaire yielding a total response rate of 90.18%. Measures of students' grit (i.e., consistency of interest, and perseverance of effort), aspirations (i.e., intrinsic aspirations - physical fitness, self-growth, affiliation, community contribution, and extrinsic aspirations - financial success, image, fame), achievement goal orientation (i.e., mastery, performance approach and performance avoidance), and perceptions of success (i.e., Success in life is pretty much determined by forces outside our control.) were administered. It was found that the majority of gifted students and non-gifted students perceived that "success is outside our control.", and chose 'hard-working' as the most influential factor on their success. 60.4% of non-gifted students chose 'wealthy family background' as the other most influential factor, whereas only 48.2% of gifted did. Gifted students had higher 'consistency of interest' and 'mastery goals' than non-gifted students. Hierarchical multiple regression analyses showed that grit (i.e., perseverance of effort) was the crucial contributors for enhancing both gifted and non-gifted students' mastery goals and performance approach goals. Results are discussed in relation to theoretical implications and school settings.

The perception of aging experience and successful aging depends on birth cohort as Korean society has rapidly changed for the last several decades. This article aims to empirically explain inter-generational difference in the perceptions of successful aging with an emphasis on the social relationships using a national survey data set by face-to-face interviews with a structured questionnaire. The respondents are classified into colony war, restoration, democratization, and information generation. Major findings are as follows: The perceptive differences are found between colony war and restoration generation, and democratization and information generation. The difference are clear in the aspects of expectation for children and parents-children relationship. The inter-generational difference remains even after controlling other relevant factors. Policies and programs, therefore, should 1) attempt to help inter-generational understanding, and 2) consider the yet-existing uniqueness of each generation.
