This study was attempted to give aids in making 'the Disability Discrimination Act' by estimating the potential Cost-Benefit in case that the discrimination on the disabled is removed. The potential benefits from this Disability Discrimination Act are calculated considering the income increase of the people with disabilities from additional employment for them and the decrease of employment levies and the public assistance benefits. The potential cost was made focusing on the following 2 expenses- the extra expenditures that the owners of companies had to invest from the employment of the disabled and the managing expenses for correcting discrimination organizations. As the result of this estimation, the potential net present value under the 7% discount rate is very high as 12,700,301 million won and the cost-benefit ratio is also great as 96.8. The consequence of the sensitive analysis in changing the discount rate also does not have great changes. As the result of these estimating results, it is known that when the discrimination is solved by the 'Disability Discrimination Act', the pure benefit of our society will become tremendous. After all, it could be said that the need for 'the Disability Discrimination Act' is emphasized and should be emphasized.

2010년을 전후로 하여 기존 미디어는 보다 강화된 컴퓨팅 기능과 플랫폼 채택, 차세대 네트워킹을 통해 스마트 미디어로 급속한 진화가 전개되고 있다. 스마트 미디어는 스피드, 인텔리전트, 소통과 개방을 통해 이용자에게 보다 편리하고 유용하며 오락적 가치를 제공하고 있으며 기업에는 새로운 비즈니스 기회를 창출하고 있다. 스마트 TV는 스마트 미디어의 핵심 서비스로 부각되고 있으며 멀티 스크린과 스마트 홈을 통해 스마트 IT 기기의 허브가 될 것으로 전망되고 있다. 본 글에서는 국내 전문가와 일반인에 대한 설문조사 결과를 바탕으로 스마트 TV에 대한 수용도를 파악하였으며 잠재 수용자의 프로파일을 분석하였다.

최근에 비정형 데이터의 잠재적 가치를 유용한 데이터로써 사용하려는 경우가 많아지고 있다. 특히 트위터는 사용자의 상태나 이벤트가 잘 나타나 있어서 하나의 사용자의 이벤트로서 간주될 수 있다. 본 논문은 트위터에서 발생하는 이벤트에 주목하여, 감기라는 이벤트를 트위터 내에서 추적하고자 한다. 추적을 위해서는 트위터를 판단할 필요가 있는데, 이를 위해 기존의 감성 사전 방식 중 하나인 통계적 사전 구축을 기반으로 키워드를 활용하여 감기 판단 사전을 구축하는 방식을 제안한다.

Objective : This study aimed to categorize the lifestyles of older adults into two types - healthy and unhealthy, and use machine learning to identify the personal values that influence these lifestyles. Methods : This cross-sectional study targeting middle-aged and older adults (55 years and above) living in local communities in South Korea. Data were collected from 300 participants through online surveys. Lifestyle types were dichotomized by the Yonsei Lifestyle Profile (YLP)-Active, Balanced, Connected, and Diverse (ABCD) responses using latent profile analysis. Personal value information was collected using YLP-Values (YLP-V) and analyzed using machine learning to identify the relative importance of personal values on lifestyle types. Results : The lifestyle of older adults was categorized into healthy (48.87%) and unhealthy (51.13%). These two types showed the most significant difference in social relationship characteristics. Among the machine learning models used in this study, the support vector machine showed the highest classification performance, achieving 96% accuracy and 95% area under the receiver operating characteristic (ROC) curve. The model indicated that individuals who prioritized a healthy diet, sought health information, and engaged in hobbies or cultural activities were more likely to have a healthy lifestyle. Conclusion : This study suggests the need to encourage the expansion of social networks among older adults. Furthermore, it highlights the necessity to comprehensively intervene in individuals' perceptions and values that primarily influence lifestyle adherence.

The purpose of this paper is to introduce and test an extension of dichotomous choice contingent valuation(DC-CV) methods of pre-test-market evaluation using the specific case of a cable telev-ision service. Specifically we used a double-bounded DC-CV approach. On the whole respondents accepted the contingent market and were willing to contribute a significant amount on average. This willingness varies according to individual characteristics and concerns about the service. It is concluded that the methods are potentially a useful tool for decision-makers in measuring the po-tential demand for a new cable television service and considering the provision of the service.

최근 기업들은 빅데이터 활용을 통해 얻은 분석결과를 고객 마케팅 및 영업 전략 수립에 적극 활용함으로써 수익성 증대 및 비용 절감이라는 기대 효익를 달성하고 있다. 이러한 흐름에 따라 기업 내 시스템 사용자를 고객으로 두고 있는 HRM시스템 역시 인사데이터 분석을 기반으로 사용자의 기호와 요구사항을 반영한 가치 있는 정보를 제공해줌으로써 기존 기업 고객 이외에 잠재적인 고객층을 확보할 수 있는 맞춤형 HRM 시스템으로 진화해야 할 것이다. 본 연구에서는 빅데이터 기반의 인사데이터 분석의 필요성과 국외 인사데이터 분석 활용사례를 살펴보고 이를 기반으로 빅데이터 분석기술을 활용하여 사용자에게 가치 있는 정보를 제공해주는 개인화된 맞춤형 HRM시스템을 제안 및 설계하고자 한다.

This study aims to examine the effects of native advertising on consumer-brand relationship quality (BRQ) formation of the potential consumers in the context of an automotive brand. Specifically, the study verifies (1) whether the respondents cognize the content of native advertisement as an advertisement and (2) how the value dimensions of native advertising impact BRQ through brand attitude (BAT). To fulfill the purposes, the researchers categorized three types of advertisements (product, brand and non-commercial) and then showed three manipulated stimuli to potential consumers in the automotive market before measuring. The findings drawn from the 345 valid cases are as following. First, the rate of respondents' advertising recognition is low in the non-commercial advertisement, while it is high in ones of product and brand. Second, most of the respondents perceive less irritation toward the native ads, especially toward the non-commercial advertisement. Third, the entertainment and informativeness of native advertising positively influence BRQ, while the effect of irritation on BRQ is negative. Also, the effects of advertising value dimensions on BRQ are all mediated by BAT.

This study aims to validate a tool evaluating MOOCs for higher education from the perspective of education service. Based on the results of related researches, a potential model for evaluating MOOCs (4 factors and 8 sub-factors) was made. An evaluation tool consisting of 18 survey items was delivered to 138 college students. After data cleaning, 136 surveys were used for exploratory factor analysis (principal component analysis. varimax rotation) and reliability analysis that confirmed the fitness of the potential model. Four exploratory constructs and seven sub-factors were extracted: Factor I was labeled as 'Systemic Learning Experience,' Factor II, 'Value Experience,' Factor III, 'Co-creation of Value Experience,' and Factor IV, 'High Order Learning Experience.' Reliability estimates using Cronbach's alpha indicated that the evaluation tool had good internal consistency. In conclusion, the evaluation tool for MOOCs in higher education was proven to be valid and reliable.

With the introduction of proptech, this study aims to find out the changes and necessity of introducing blockchain technology, one of the most popular technologies, in real estate electronic transactions. In addition, it is intended to develop evaluation indicators that classify newly created values within real estate electronic transactions and calculate the relative importance of each value area through technology application. To this end, the value that can be created when applying blockchain technology to real estate electronic transactions was classified according to the hierarchy, and considering that the evaluation criteria are complex and the importance can be measured differently depending on various factors, an analysis was conducted according to the AHP method for experts in practical and academic fields. As a result of the analysis, general value showed the highest importance in the first dimension, and digitalization of real estate information showed the highest importance in the second dimension.

The purpose of this study is to look through the progress of Yeosu Exposition ex-post facto service, to survey the cognition degree of the general public for it, and to estimate the nonmarket value. For such a reason, this paper examines the planning direction and enforcement situation of ex-post facto service first and then conducts a cognition degree survey of the 900 general public in the nation. Also, this paper carries out the nonmarket value of Yeosu EXPO ex-post facto service using CVM. Estimation results is that the annual value of it is 50.8 billion won and the total value for 5 years is 217.1 billion won. These results mean that there is nonmarket high value besides general market value for Yeosu EXPO ex-post facto service, and government should consider this to determine the future of it.
