A Machine Learning Approach Using Spatially Explicit K-Nearest Neighbors for House Price Predictions
Spatial data has distinctive properties that differentiate it from non-spatial data. One prominent characteristic is spatial autocorrelation (SA). When machine learning techniques are applied for spatial data modeling, they require spatially explicit consideration. If these inherent spatial structures are ignored, models may produce biased predictions. However, integrating this property into the model yields additional spatial insight, thereby en…
Delineations for Police Patrolling on Street Network Segments with p-Median Location Models
Police patrolling intends to enhance traffic safety by mitigating the risks associated with vehicle crashes and accidents. From a view of operations, patrolling requires an effective distribution of resources and often involves area delineations for this distribution purpose. Given constraints such as budget and human resources for traffic safety, delineating geographic areas optimally for police patrol areas is an important agenda item. This pap…
Exploring the Influence of Sociodemographic Backgrounds on Money Mule Recruitment Types in South Korea
This study explores the influence of socio-demographic characteristics on money mule recruitment types in South Korea. Analyzing data from 543 apprehended money mules, probabilities were calculated for each group's involvement in recruitment types. Using class membership probability estimates from six machine learning methods, the research investigates the probability relationship between socio-demographic characteristics and recruitment types. F…
Tension, War, Peace, and Unification
This article analyzes South Korea’s unification policies and makes ethical suggestions in light of Christian theological and ethical theories of war and peace. Since 1948, South and North Korea have repeatedly confronted each other with heavily armed forces. Unification would be considered the achievement of the Korean people’s endeavour to deter military warfare and promote peace between the two Koreas. In this regard, it is understandable that …
Intercultural Reflections on Life
심각한 환경적 위협 앞에서 온 인류가 겪고 있는 ‘생명(들)’의 위기의 현실을 직시할 때, 동양과 서양을 아우르는 전세계적 차원에서의 공동의 기반 모색은 절실한 요구가 되고 있다. 이 ‘공동의 기반’의 가능성을 이론적으로 충분히 또 정연하게 전개하고 발전시키는 과업이 주어졌다고 필자는 생각하며, 이를 위해 생명에 관한 간문화적 탐구를 수행하고자 한다. 슈바이처가 대표하는 서양의 생명 사상과 함께 공동의 기반 위에 서야 할 동양의 생명 사상을 제시하고 둘 사이를 비교·평가하며 서로 배울 수 있는 바를 찾고자 한다. 필자가 동양에서 슈바이처의 대화상대로 삼고자 하는 대상은 유교와 민중신학이다. 유교 인간론은 인간의 고유한 특성을 ‘자기 초월’에서 찾는다. 궁극적 실재와 타자와 다른 피조물들을 향해 지속적으로 자기 자신을 개방하고 내어준다는 의미에서의 초월인 것이다. 민중신학 탐구를 위해 서남동에 주…
Prevalence of cyberbullying and predictors of cyberbullying perpetration among Korean adolescents
Prevalence and predictors of smartphone addiction proneness among Korean adolescents
Predictors of online game addiction among Korean adolescents
Given the rapid growth of mobile games, one of the main purposes of this study is to analyze the effect of online gaming on addiction by classifying it into PC online gaming and mobile gaming. This study aims to analyze the extent to which playing games after midnight affects addictive behavior. In addition, this study analyzes the impact of game genres, parental factors, the leisure environment and relationship satisfaction on game addiction. Ab…
Smartphone Addiction and Application Usage In Korean Adolescents
We examined adolescent application usage related to smartphone addiction and also explored mediation strategies used to prevent their addiction. Participants were 3,000 adolescents in grades 7 to 12 who completed an online survey. According to the findings, frequent use of social networking site applications (apps), game apps, and video apps tended to exacerbate adolescents' addiction to smartphones. Mediation strategies negatively related to sma…
