The purpose of this study is to investigate the effect of factors related to consumer lifestyle and media usage on the adoption of Nscreen service, which is fundamentally changing both the competitive landscape for business and the daily lives of consumers. The data of 8,524 consumers used in this study were drawn from the first Korea Media Panel Study in 2012 of Korea Information Society Development Institute and the characteristics of adopters and non-adopters were compared. The study also aims to explore the usage pattern of Nscreen as well as antecedent variables that affect the innovative service usage. Logistic regression analysis shows various factors affects the acceptance of this innovation. This is only a first step in the important process of understanding the nature of relationship between consumer lifestyle and the adoption of Nscreen service. Gaining a comprehensive understanding of the drivers of Nscreen usage will help engineers and marketers to develop effective strategies that meet consumer needs for innovative services.

It is very important to understand the factors affecting the occurrence of vacant houses in research on them. The purpose of this study is to analyze the factors affecting the rural vacancy occurrence. This study set 121 research areas and selected eight independent variables (Aged house rate, housing transaction rate, house diffusion ratio, local extinction index, net migration rate, regional aging index, the ratio of the number of employees to population and financial independence rate) and one dependent variable (vacant house rate). As a result of the study, first, both Model 1 for the entire general agricultural fishing village area and Model 2 for the county (gun) area were statistically significant, there was no problem with the independence of residual. Second, local extinction index and aged house rate had a statistically significant positive (+) relationship in both Model 1 and Model 2. Third, diffusion ratio of house had a statistically significant positive (+) relationship only in Model 1, and housing transactions rate had a statistically significant negative (-) relationship in Model 2. The implications of the study were drawn as follows: First, the increase in the house diffusion ratio without growth in households and population suggests the increase of the probability of the vacancy occurrence in the area, and the higher the aged house rate, the higher the probability of the vacancy occurrence. Second, for the revitalization of housing transactions, it is necessary to have an investment inflow in the area for mid- to long-term development. Third, local extinction index has a significant relationship with vacant house rate, it is necessary to introduce a local revitalization policy from a long-term perspective for the permanence of the area.

개인화를 위한 협력적 추천의 대표적인 방법인 최근접 이웃 방법은 적용이 쉽지만, 사용자의 선호도 정보가 적을 경우 회소성(sparsity)문제와 사용자 수가 많은 경우 수행 속도가 느려지는 범위성(Scalability)문제 그리고 사용자간의 가중치가 결여되었다는 점에서 추천의 정확성이 떨어진다. 신경망 기반 추천은 자료의 유형에 상관없이 데이터의 처리가 용이하고, 사용자간의 가중치를 학습할 수 있으며, 내용 정보, 인구통계학적 정보 등을 입력 노드에 추가함으로써 희소성 문제를 해결할 수 있으나. 범위성 문제는 존재한다. 따라서 본 논문에서는 최근접 이웃 방법으로 클러스터링 한 유사한 사용자 또는 항목들을 고려한 신경망 기반 추천 방법을 제안하여 범위성 문제를 최소화시킴으로써 추천의 성능을 향상시키고 있다. 제안한 추천 방법의 타당성을 보이기 위해 EachMovie데이터를 이용하여 기존 신경망 추천과 비교 실험하여 성능을 분석한다.

With regard to recently emerged problems of smartphone addiction among adults and adolescents, this paper researched upper-grade elementary students depending on various demographic factors that have not been studied thoroughly so far. The survey was conducted on 1570 students in grades 4~6 of schools in Gyeonggi province. Results showed that, first, the average rate of smartphone ownership was about 66%. Second, about 1% of the students belonged to high-risk group, 5.7% to at-risk group, and normal user group was 93.3%. Third, based on the demographic factors, grade and academic achievements each was significantly correlated to the type of addiction group. For example, students with poor academic performance or in higher grade were more likely to be highly addictive. Fourth, both groups of at-risk and of normal-user pertaining to these factors - in urban areas, male students, sixth-grade, in dual income families - showed higher addictiveness score. But they were contrasted in the aspects of household economy and academic performance: at-risk group was more addictive in affluent families or excellent academic performance, whereas normal-user group had higher level of addictiveness in case of poor families or lower academic performance.

This research aims to offer the information required for demand increase on marketing strategy level by investigating Mudeungsan visitors' demographic characteristics and social economical variables. To accomplish this study, the proper analyzing model needs to be applied because a grave error of parameters will be led if regression model appropriate for analyzing the data of a continuous probability variable is applied, in case that dependent variable is a discrete random variable which have a discrete probability distribution. Therefore data analysis was performed with Poisson model. However, as the data was showing an overdispersion, parameter was estimated with the Binomial Poisson model able to cover the problem. As a result, some explanatory variables turned out to be significant such as visitor's age, occupation, preferred season to visit, type of company, five days working, and preferring type of tourism. Author could offer to the national park the information about characteristics of core market revealed and marketing strategy for it, based on those influential variables.

Most banks use only demographic information such as gender, age, occupation and address to segment customers, but they do not reflect financial behavior patterns of customers. In this study, we aim to solve the problems by using various big data in a bank and to develop customer segmentation method which can be widely used in many banks in the future. In this paper, we propose an approach of segmenting clustering blocks with bottom-up method. This method has an advantage that it can accurately reflect various financial needs of customers based on various transaction patterns, channel contact patterns, and existing demographic information. Based on this, we will develop various marketing models such as product recommendation, financial need rating calculation, and customer churn-out prediction based on this, and we will adapt this models for the marketing strategy of NH Bank.

The purpose of this study was aimed to analyze factors affecting on continuous intention to use of Smartphone based on the innovation diffusion theory. Also, by using the demographic characteristics were compared whether the difference in the loyalty on between user group of iOS and Android platform. Predictor factors were selected innovation, convenience, economic cost, social influence, communication channel, compatibility and complexity suggested on the innovation diffusion theory. Participants of this study were 278 Smartphone users in Busan city and Gyeongnam province in accordance with convenience sampling. IBM SPSS Statistics 19 were employed for descriptive statistics, Smart PLS(partial least squares) was employed for confirmatory factor analysis and path analysis of casual relationship among variables and effect. Analytical results show that all paths except path from complexity to the continuous intention to use and loyalty are significant. The comparison loyalty on between user group of iOS and android platform are significant. This study suggests practical and theoretical implications based on the results.

통계청에 의하면 65세 이상 인구가 2024년 1,000만명을 도래할 것으로 예측하고 있으며, 노인인구 증가와 함께 노인치안 이슈들은 매년 증가하고 있다. 특히, 경찰청 자료에 따르면 최근 5년간 노인범죄피해는 매년 증가하고 있는 것으로 나타났다(경찰청, 2021). 치안서비스 대상에서 주요한 영역을 차지하게 될 노인을 대상으로 한 범죄예방정책을 마련하기 위하여 범죄피해노인의 특성에 관한 연구를 함에 있어 연도별 노인의 범죄피해영향요인의 차이가 있는지를 이 연구에서는 분석하고자 하였다. 따라서 이 연구에서는 한국형사·법무정책연구원의 2014년, 2016년, 2018년 전국범죄피해조사 2차 자료를 활용하였으며, 그 중 만65세 노인대상 자료만을 추출하여 2014년 1.921명, 2016년, 2,935명, 2018년 2,707명을 각각 최종분석에 활용하였다. Spss ver 21. 통계프로그램을 활용하여 로지스틱회귀분석을 실시하였으며, 연구결과 2014년에는 사회적 무질서 수준과 노인범죄피해와의 관계성이 높았다면, 2016년에는 물리적 무질서 수준과 노인범죄피해와의 관계성이 높았고, 2016년과 2018년에는 독거노인과 빈 집으로 가구가 노출되는 시간이 긴 정도가 노인범죄피해와의 관계성이 높은 것으로 볼 수 있었다. 이러한 연도별 노인 범죄피해 영향요인의 변화를 실증연구를 통해 검증함으로써 추후 노인범죄예방을 위한 정책마련의 자료로 활용하고자 한다.
