Purpose: Adolescents with same-sex or both-sex sexual experience face disproportionate health risks, yet research has predominantly examined single health problems rather than their multidimensional patterns. This study employed latent class analysis (LCA) to identify distinct health typological classes among Korean adolescents and characterize the distribution of sexual behavior patterns across these classes. Methods: We analyzed 278,066 middle- and high-school students in the 2013?2016 Ko rea Youth Risk Behavior Survey. The LCA used 17 indicators encompassing sexual be havior patterns, health behaviors, health perceptions, and mental health. Complex-sam ple weighted analyses examined associations between latent classes and sociodemo graphic characteristics, sexual behaviors, and diseases. Results: Four distinct classes were identified: mental health high-risk group (10.1%), sub stance use high-risk group (6.5%), average group (36.3%), and healthy group (47.1%). Adolescents with same-sex or both-sex sexual experience were disproportionately con centrated in the two high-risk classes, comprising 3.3% of the mental health high-risk group and 4.1% of the substance use high-risk group, compared with only 0.3% and 0.5% of the average group and the healthy group. The mental health high-risk group exhibited extremely elevated prevalence rates of suicidal ideation (96.2%), depressive symptoms (88.5%), and suicide attempts (27.5%), while the substance use high-risk group showed high rates of smoking (82.4%) and alcohol use (84.6%) but better mental health. Conclusion: Adolescents with same-sex or both-sex sexual experience demonstrate health inequality through disproportionate classification in the mental health high-risk group and the substance use high-risk group. The findings underscore the need for inte grated interventions combining mental health support and substance use prevention.

Melatonin plays a crucial role in various behavioral and physiological aspects of animals, including regulating their circadian rhythms. This review provides a comprehensive evaluation of the multifaceted effects of melatonin on animal behavior, such as temperament, stress, and aggression regulation. The focus is on the complex interactions between melatonin and the hormonal and neurotransmitter systems, highlighting how melatonin interacts with cortisol, serotonin, and dopamine to influence behavior. Additionally, it investigates the effects of melatonin on the hypothalamic?pituitary?gonada (HPG) axis and stress responses, emphasizing its potential to improve stress management and social interactions, thereby enhancing animal welfare. The review also examines the seasonal variations of melatonin and its impact on aggression and reproductive activities related to photoperiods, as well as its effects on learning and memory to suggest improvements in animal training methods and practices. Furthermore, it discusses the influence of melatonin on appetite and physical activity regulation, implying its involvement in metabolic processes. In conclusion, further research is needed to elucidate the complex mechanisms underlying the extensive influence of melatonin on animal behavior. Through this review, the aim is to integrate the overall knowledge about melatonin and animal behavioral temperament and to propose new research areas for animal management based on behavioral and hormonal regulation.

This study aims to identify whether unique anxiety profiles in school-age children and parents exist, and to determine whether these profiles differ from each other based on anxiety control beliefs (ACB) and parenting behavior. A total of 265 children (C) in grades 4 to 6 and their mother (M) and father (F) participated in this study. Latent profile analysis (LPA) revealed three anxiety profiles: (1) C high-MF mid profile, (2) CMF low profile, and (3) F high-CM mid profile. A multivariate analysis of variance (MANOVA) showed profile differences except for mother’s negative behavior. It is suggested that children’s cognitive vulnerability and parenting behaviors were likely to aggravate anxiety issues within a family contexts.

PurposeThis secondary data analysis examined the relationship between sleep patterns (including bedtime and wake-up time), chronotype, and depressive symptoms in adolescents aged 13~18 years. MethodsData were derived from the 19th Youth Risk Behavior Survey conducted in 2023. Of the 52,880 respondents, 5,893 were excluded, resulting in a final analytic sample of 46,987 adolescents. Complex sample logistic regression analyses were conducted using SAS version 9.4 to investigate the effects of sleep patterns and chronotype on depressive symptoms. ResultsAmong the 46,987 participants, 11,967 reported depressive symptoms, yielding an estimated prevalence of 25.3%. Statistically significant differences in bedtime, wake-up time, sleep duration, and chronotype were identified between adolescents with and without depressive symptoms (p < .001). The mid-sleep time on free days corrected for sleep debt on school days was significantly later among those with depressive symptoms (5.49 ± 0.03) compared with those without (5.36 ± 0.02; p < .001). Significant correlates of depressive symptoms included sex, living with family, household income, school grade, current drinking and smoking, habitual drug use, perceived health status, anxiety, stress awareness, loneliness, and sleep duration. Each additional hour of sleep was associated with a 0.98-fold lower risk of depressive symptoms (95% confidence interval = 0.96~0.99, p = .021). ConclusionThis study demonstrated that sleep duration, sleep patterns, and chronotype are associated with depressive symptoms in adolescents. Interventions should target extending sleep duration through earlier bedtimes and encouraging a shift from evening-type to morning-type chronotypes, which may help alleviate depressive symptoms.

비디오스트리밍 서비스와 같은 클라우드 컴퓨팅의 확장성 제고를 위하여, 개인 사용자들의 컴퓨팅 자원을 활용하는 기술이 널리 사용되고 있다. 이와 같이 노드의 도움을 받는 시스템은 효율성 극대화를 위하여, 노드들의 행동을 정확히 예측하는 것이 매우 중요하다. 비록 P2P시스템관련 연구가 많이 진행되어 왔으나, 대부분 한 시스템 전체에 대한 특성을 수집 및 분석하는 연구가 주를 이루고 있다. 따라서 각 노드들의 행동 패턴을 분석하는 연구는 초기 단계에 머물러 있다. 본 연구에서는 각 노드들의 가용성에 대한 행동 패턴을 자동으로 분류하기 위한 기술을 제시하고, 그 분류 결과를 수동으로 된 것과 비교한다. 실제 운영되고 있는 P2P시스템에 참여하고 있는 노드들의 사용 기록에 대하여 다양한 조건으로 k-means 클러스터링을 적용하였다. 분석 결과에 따르면, 노드의 가용성 변화 기준으로 다양한 숨겨진 행동 패턴이 존재하는 것을 볼 수 있었다. 본 연구는 노드의 불확실성에 미리 대비하기 위한 시스템 설계에 활용 될 수 있을 것으로 기대된다.

To increase the scalability of cloud computing, utilizing resources of individual users has been widely adopted especially in video streaming services. Accurately predicting behavior of user nodes is critical to achieve a high efficiency in such a peer-assisted system. Though there have been many measurement studies on peer-to-peer systems, most of them have focused on the design and characterization of the systems. Thus the behavior patterns of individual nodes have seldom been studied. In this paper, we present new techniques for classifying behavior of nodes in terms of availability and compare them with naive manual classification. We apply a k-means clustering algorithm with various classification criteria on real trace data of a peer-to-peer system. Our analysis shows that there are various hidden behavior patterns with respect to the transition of availability. Our study will give a useful hint to a system designer in handling churns more efficiently based on the peer classification.

In normal cells, cell to cell contact at full cell confluency inhibits cell growth. However, if cell to cell contact is being dissociated, normal cells reach their end of life by the phagocytosis of macrophage via 'programmed cell death', named 'apoptosis'. On the other hand, in cancer cells (especially, cancer stem cells), cell to cell contact can not inhibit cell growth. As a result, cancer stem cells can grow beyond full cell confluency. When cancer cells reach full cell confluency, they either stay at confluence stage or must be made transition from epithelial to mesenchymal form by cadherin switch(antiapoptotic program). These behavioral patterns of cancer stem cells are called "EMT"[2,20]. The underlying causes for such difference have not been known well until now. But this difference is assumed to be occurred by loss of cellular differentiation and coordination of proliferation[5]. As approaching the reason of such disorders with mechano-molecular biology, it was predicted using a mechanobiological model that if cellular unbalanced force is caused between cell to ECM and cell to cell adhesion, the molecular crosstalk is disintegrated between E-cadherin and EGFR Signaling Networks in cell to cell contacts and the attributes such as morphological change of cancer cells, motility, invasion, anticancer drug resistance, etc are acquired, and they were established by experimental method[5]. This study is to report the research results for an idea that the neural network development is a meaningful method of prediction system on cancer behavior patterns through such methods.

The purpose of this study is to summarize the comprehensive opinions on what the solo consumers feel when engaging in touristic activities. In addition, this research systematically studies what the solo consumers feel when they visit restaurants or cafes and consume them. Also, the research explored specific opinions on the advantages and disadvantages while doing consumption activities alone. When traveling alone, it was found that the safety of the tourist destination was most important, and that the burden of accommodation expenses was felt more than that of group tourists. It was found that they felt uncomfortable because of the limitations of the one-person menu because they ate alone at tourist attractions. In addition, since it has nothing to do with the benefits that group tourists easily receive, such as the group tourist discount system, it was found that they wanted a discount system that could replace them. Amid growing social interest in the rapidly increasing number of soloists in recent years, the tourism industry and the restaurant industry have not conducted much in-depth research on the characteristics of solo consumers. Therefore, this study can be said to present information that can provide meaningful implications to the restaurant industry and the tourism industry, which need to actively promote to solo consumers in the future.

This study examined the differences in health behavior, type A behavior patterns, coping styles, physical symptoms between Korean Adventists and non-Adventists. The participants were 346 college students (129 Adventists and 217 non-Adventists) and 335 adults over 30 years old (158 Adventists and 177 non-Adventists). The instruments utilized in the present study were the Framingham Tape A Behavior Pattern Scale, AUDIT(Alcohol Use Disorders Identification Test), the Multidimensional Coping Scale, and Chon's Physical Symptom Questionnaire. Results indicated that Adventists' dietary styles were significantly different from non-Adventists' dietary styles, and Adventists consumed less alcoholic beverage and cigarette than non-Adventists did. Although Adventist's coping styles were different from non-Adventist's coping styles, there were no differences in level of type A behavior pattern and reported physical symptoms between those two groups. A forward stepwise regression analysis revealed that type A behavior patterns accounted for most variance of physical symptoms. Results of this study were discussed with antecedent studies on Adventist's health in United States and other countries.

본 연구에서는 성관계 제안을 거절당한 사람의 행동을 중심으로 연인 관계의 성적 의사소통을 살펴보았다. 연구 1에서는 시나리오를 이용해서 성관계 제안을 거절당한 사람의 행동 양상을 검토하였다. 연구 2에서는 거절당한 성별 조건에 따라서 참여자들이 거절당한 사람의 행동을 어떻게 예상하는지를 탐색하였다. 또 상대의 설득으로 성관계에 응할 때, 설득한 사람과 응한 사람의 관점에 따라서 참여자들이 성관계 동의 수준을 어떻게 평가하는지를 살펴보았다. 거절당한 사람의 행동 양상은 ‘불쾌감 표출과 조종’, ‘관계 변화 우려’, ‘접근과 설득’, ‘존중과 수용’, ‘기분 배려’의 다섯 요인으로 도출되었다. 성관계 제안을 거절당한 남성의 행동으로, 남성 참여자는 ‘존중과 수용’을, 여성 참여자는 ‘접근과 설득’을 가장 높게 예상하였다. 성관계 제안을 거절당한 여성의 행동으로, 남녀 참여자 모두 ‘존중과 수용’을 가장 높게 예상하였다. 또 남성이 여성을 설득해서 성관계할 때, 여성 참여자는 남성 참여자보다도 성관계에 응한 여성이 지각한 동의 수준을 더 낮게 평가하였고, 남성이 지각한 여성의 동의 수준을 더 높게 평가하였다. 여성이 남성을 설득해서 성관계할 때, 남성 참여자는 여성 참여자보다도 성관계에 응한 남성이 지각한 동의 수준을 더 높게 평가하였다. 이러한 결과는 성 각본과 인지부조화로 논의하였고 데이트 성폭력의 위험성을 제언하였다.

his study examined sexual communication in romantic relationship focusing on the patterns of behavior of those whose sexual advances have been rejected. Study 1 investigated the behavior patterns of those who were rejected when making sexual advances by using a romantic relationship scenario. Study 2 explored how participants predicted the behavior patterns of those who were rejected depending on the gender of the rejectee. We also analyzed how participants evaluated the level of consent to sexual relations depending on the viewpoint of those who made the sexual advance or those who compliance, when the sexual relations by persuasion. The behavior patterns of those who were rejected were classified into five factors including ‘showing discomfort and manipulation’, ‘concern about changes in relationship’, ‘approach and persuasion’, ‘respect and acceptance’, and ‘consideration of feeling.’ In condition where the man was rejected, male participants were most likely to do ‘respect and acceptance’ behavior, whereas female participants were most likely to do ‘approach and persuasion’ behavior. In condition where the woman was rejected, both male and female participants were likely to do ‘respect and acceptance’ behavior. In condition where man had a sexual relation with women through persuasion, female participants rated the perceived women's level of consent who complied with the sexual relations lower than male participants. They also rated the men's perceived women's level of consent higher than male participants. In condition where woman had a sexual relation with men through persuasion, the male participants rated the perceived man's level of consent who complied with the sexual relations higher than female counterparts. Such results were discussed in sexual scripts and cognitive dissonance, and suggested of the risk of date rape.

In this paper cross-cultural similarities and differences in child and adolescent behavior problem patterns were examined by comparing the Child Behavior Checklist data collected in Korea and the U.S. The Korean CBCL data were from the clinic referred sample of 952 boys and 426 girls between the ages of 4 and 16 and the non-referred sample of 778 boys and 740 girls in the same age range recruited from schools. The U.S data were from the standardization sample for the original CBCL as reported by Achenbach & Edelbrock(1983). The results were as follows. First, comparisons of behavior problem syndromes empirically derived from factor analyses of the Korean and American CBCL revealed considerable similarities, particularly in externalizing syndromes such as Aggressive and Delinquent syndromes. There was less similarity in the pattern of internalizing syndromes such as Anxious and Depressive syndromes. Second, Korean children and adolescents compared to their American peers showed significantly lower scores on the Aggressive and Delinquent scales but significantly higher scores on internalizing scales such as Somatic Complaints, Social Problems and Attention Problems. Third, there was considerable similarity in the type of problems frequently reported by parents from the two countries, but externalizing problems were much more likely to get clinic referral in the U.S. than in Korea. The crossnational differences outlined above were discussed in terms of cultural differences in childrearing practices, criteria for judgment of behavioral deviance, and beliefs and attitudes about mental health problems.

Purpose: The objective of this study was to investigate the relationships between sleep quality, fatigue, depression and health promoting behavior by shift-work patterns in university hospital nurses. Methods: A cross-sectional, descriptive survey was conducted using a convenient sample. The self-administered questionnaires were given to 165 nurses(shift workers 91, non-shift workers 74) employed in two university hospital located in Seoul and Gyeunggi-do. Data were collected from February to March, 2010. Results: The shift workers showed significantly lower sleep quality and health promoting behavior, and higher fatigue than non-shift workers. There were significant correlations between fatigue, depression and health promoting behavior in shift workers. There were significant correlations between sleep quality, fatigue, depression and health promoting behavior in non-shift workers. In multiple linear regression analysis, after controlling for total work experiences, predictor of health promoting behavior in shift workers was only fatigue (β =-.29, p<.001). Predictors of health promotion behavior in non-shift workers were depression (β =-.37, p=.002) and fatigue (β =-.27, p=.023). Conclusion: This study was not clear why sleep quality does not have a comparable effect on health promotion behaviors of shift-workers as well as non-shift workers. However, future research is needed to determine the various risk factors influencing on health promotion behaviors by which shift-work pattern exacerbates fatigue.

This study continues the entire process of researching how to build a pet digital twin, and continues to draw conclusions through cluster surveys and analysis of experimental results. First, with the advancement of AI models, the Transformer model achieved 98.5% accuracy in processing time-series sensor data, demonstrating superior performance compared to existing CNN-LSTM (Convolutional Neural Network-Long Short-Term Memory) (95.8%) or RF (Random Forest) (91.2%). Second, to overcome the differences in body shape between dog breeds in vision-based pose estimation using multimodal and shape-adaptive technologies, a family-aware model such as AniMer is essential, and accuracy is secured through fusion with an IMU (Inertial Measurement Unit) sensor. Third, the architecture, which applies its own framework and the MQTT (Message Queuing Telemetry Transport) protocol, a cloud-centric lightweight protocol, through platform standardization, enables real-time synchronization between physical sensor data and virtual engines (Unity/Unreal Engine), and provides the foundation for a bio-digital twin that visualizes even invisible information such as bioenergy through software sensors. Beyond a simple technological endeavor, companion animal digital twins will become established as a “digital companion” technology that expands communication channels with companion animals who cannot speak and dramatically improves their quality of life.

본 연구에서는 온라인 게임인 ‘리니지’의 초등학생 게이머들을 대상으로 온라인 게임 라이프스타일과 교우관계에 어떤 연관성이 있는지 살펴보고자 한다. 리니지 게임을 하는 집단과 하지 않는 집단이 온라인 공간에서 보이는 행동방식과 교우관계를 비교한 결과, 온라인 게임집단은 일반집단보다 교우관계에서 사교성, 자기주장, 규범준수, 성취욕이 전반적으로 낮았다. 그러나 같은 온라인 게임을 할지라도 게임의 행동방식은 일탈적, 차별주의적, 개인주의적, 공동체적 게이머라는 네 유형으로 분류되었으며, 차별주의적․일탈적 게이머는 사교성이 나머지에 비해 높았고, 자기주장성은 차별주의적 게이머에게서 가장 높았다. 이러한 결과를 통해 게임 이용 여부 자체보다 그 게임 속에서 보여주는 행동방식이 게이머의 교우관계의 차이를 보여주는데 유의미한 기준임이 확인되어, 리니지와 같은 온라인 게임에 대한 자녀생활지도 참고자료로 활용될 수 있을 것이다.

The purpose of this research was to find differences of children's behavioral pattern between players and non players of the online game "Lineage" in on-line and off line space. As a result, social behaviors of children who play online games were less active than who don't. Based on their motive and behavior pattern in online world, four behavior patterns in online world were identified; “Single-Oriented”, “Community-Oriented”, “Off-Real World” and “Discriminative.” Off-Real World and Discriminative players were more sociable than Single-Oriented and Community-Oriented players. And Discriminative player has more self assertive attitude than others. This study may serve as a model to understand how players will respond to the various game features and how they adopt the virtual world for their interpersonal relationships.

본 연구에서는 내재화 장애 청소년과 외현화 장애 청소년의 문제행동에 대한 부모 보고와 청소년 보고가 어떤 양상으로 나타나는 지 알아보고자 하였다. 내재화 장애가 있는 청소년 29명(내재화 장애 집단)과 외현화 장애가 있는 청소년 37명(외현화 장애 집단)에게 한국판 청소년 자기행동 평가 척도(Korean Youth Self-Report: K-YSR)를 실시하였고, 부모 66명에게는 한국판 아동 청소년 행동평가 척도(Korean Child Behavior Checklist: K-CBCL)를 실시하였다. 자료분석을 위해 두 집단의 K-CBCL과 K-YSR 11개 증상척도에 대해 t검증 하였고, 진단구분에 영향을 미치는 척도들을 알아보기 위해 판별분석하였다. 아울러 내재화 장애 집단과 외현화 장애 집단 각각에서 문제행동에 대한 부모-청소년 보고 간의 일치도를 알아보기 위해 적률상관 분석을 하였다. 또한 청소년의 문제행동에 대한 부모 보고와 청소년 보고의 상대적 심각도가 청소년의 장애 유형(즉 내재화 장애와 외현화 장애)과 유관성이 있는 지 알아보기 위해 χ2 검증하였다. 그 결과, 비행, 내재화 문제 및 외현화 문제 증상척도는 부모 보고와 청소년 보고 둘 다에서 내재화 장애 집단과 외현화 장애 집단의 문제행동을 잘 반영해주고 있었다. 청소년의 문제행동에 대한 부모와 청소년 보고 간의 일치도는 낮았다. 청소년의 장애 유형과 부모와 청소년의 문제행동 보고에서의 상대적 심각도는 유의한 관련성이 없었다. 이러한 결과는 본 연구대상의 인구통계학적 및 임상적 특징의 영향일 수도 있다. 그러나 청소년의 문제행동에 대한 정보제공자간의 일치여부나 문제행동의 상대적 심각도를 평가하는 것을 넘어서서, 부모-청소년 간의 상호작용 혹은 심각도에 대한 정보제공자의 지각을 고려해 볼 필요가 있음을 시사한다. 본 연구의 제한점과 향후 연구방향이 논의되었다.

The purpose of this study was to examine patterns related to parent and adolescent reports of problem behaviors in adolescents with internalization and externalization disorders. The Korean Youth Self-Report (K-YSR) was administered to 29 adolescents with internalization disorders (i.e., the internalization disorder group) and 37 adolescents with externalization disorders (i.e., the externalization disorder group). The Korean Child Behavior Checklist (K-CBCL) was administered to 66 parents. A t-test was used on 11 symptom scales of the K-CBCL and K-YSR to identify differences between the two groups. In addition, a discriminant function analysis was conducted to identify symptom scales which affected the diagnostic classification decisions. Additionally, agreement between parent and adolescent reports in the two groups was analyzed using Pearson's Product Moment Correlation. Further, a Chi-test was used to identify contingencies in the relative severity of parent and adolescent reports of problem behaviors depending on the type of adolescent's disorder (i.e., internalization or externalization disorder). Delinquent behavior, internalization and externalization symptom scales well reflected the problem behaviors both of the internalization and externalization disorder groups with respect to the parent and adolescent reports. Agreement between parent and adolescent reports of problem behaviors in adolescents were low. Further, the type of adolescent disorder and the relative severity of the problem behaviors as indicated by the parent and adolescent reports were not significantly related. These results may have been influenced by the demographic and/or clinical characteristics of the subjects. However, beyond assessing the agreement between informants or severity on behavior problems, these results suggest the need to consider the parent-adolescent interaction or the informant's perception regarding the severity of behavior problems. Finally, the limitations of this study as well as suggestions for future research have been discussed.

컨텍스트 인식 환경에서 개인화 추천 서비스를 제공하기 위해서는 수집된 컨텍스트 정보를 빠르게 분석하고, 효과적으로 사용자의 목적을 추론할 수 있어야 한다. 그러나 모바일 장비에서 수집되는 컨텍스트는 환경에 따라 데이터의 차이가 발생함으로 인해 기존의 추론 알고리즘을 그대로 적용하기에는 적합하지 않고 모바일 환경에 적합한 효율적인 알고리즘이 필요하다. 본 연구에서는 정보의 누락이나 오류 등으로 인한 손실을 최소화하기 위해 나이브 베이즈 분류기를 사용하여 행동 패턴을 분류하였다. 또한 사용자의 성향을 효과적으로 학습하고 행동 목적을 추론하기 위하여 패턴 매칭 기법을 사용하였다. 제안한 개인화 추천 서비스 시스템을 스마트폰에서 어플리케이션을 추천하는 서비스를 적용하여 정확도를 평가하였다.

In order to provide with personalized recommendation service in context-awareness environment, the collected context data should be analyzed fast and the objective of user should be able to inferred effectively. But, the context collected from the mobile devices is not suitable for applying the existing inference algorithms as they are due to the omission or uncertainty of information and the efficient algorithms are required for mobile environment. In this paper, the behavior pattern was classified using naive bayes classification for minimize the loss caused by the omission or error of information. And pattern matching was used to effectively learn of the users inclination and infer the behavior purpose. The accuracy of the suggested inference model was evaluated by applying to the application recommendation service in the smart phones.

Results : Female workers' prevalence rate of metabolic syndrome was 12.1%, and, among their health behaviors, the variables having significant effects on metabolic syndrome were drinking and smoking. Conclusion : Therefore, to prevent female workers' metabolic syndrome, multiple intervention programs related to obesity, drinking and smoking should be introduced and applied, and the intervention programs for vulnerable workers with low household income and low education levels should be actively developed and carried out.

본 연구의 목적은 환경적 요인인 양육스트레스와 모의 개인 특성 변인들을 통합한 다차원적 접근에 기반하여 모의 군집유형을 파악해보고, 각 유형별로 유아기 자녀의 문제행동에 차이가 있는지를 살펴보는 것이다. 이를 위해 만 3-6세 유아의 모 455명을 대상으로 자기보고식 설문을 통해 자료를 수집하고 군집분석과 분산분석을 실시하였다. 분석 결과, 모의 양육스트레스와 정서적․인지적 조절 및 마음챙김을 포함하는 개인적 특성에 따른 잠재 집단은 세 개 유형으로 분류되었다: (1) 조절저하 취약유형(높은 양육스트레스, 높은 정서조절곤란, 낮은 인지적 자기조절, 낮은 마음챙김), (2) 일반 평균유형(평균수준 양육스트레스, 정서조절곤란, 인지적 자기조절, 마음챙김), (3) 조절유지 양호유형(낮은 양육스트레스, 낮은 정서조절곤란, 높은 인지적 자기조절, 높은 마음챙김). 조절유지 양호유형은 다른 두 유형에 비해 자녀의 문제행동 수준이 유의미하게 낮았으나 조절저하 취약유형과 일반 평균 유형에서는 자녀의 내재화 및 외현화 문제행동에서 유의미한 차이를 보이지 않았다. 이를 바탕으로, 유아기 자녀를 양육하는 어머니의 개인특성 변인 양상에 따른 개별적 관리를 통해 향후 유아기 자녀의 문제행동의 예방뿐 아니라 이를 감소시킬 수 있는 조기개입의 가능성을 확인했다.

The purpose of this study was to identify cluster types based on maternal child-rearing stress and individual characteristics, all of which are known to have important associations with young children behavioral problems. To this end, 455 mothers of children aged three to six were recruited for self-reported questionnaires. To analyze the data, cluster analysis and multivariate analysis of variance were conducted. Three potential groups emerged: (1) low regulation weak type (high child-rearing stress, high emotional dysregulation, low cognitive self-regulation, and low mindfulness), (2) general average type (an average level of child-rearing stress, emotional dysregulation, cognitive self-regulation, and mindfulness), and (3) high regulation moderate type (low child-rearing stress, low emotional dysregulation, high cognitive self-regulation, and high mindfulness). The high regulation moderate type scored significantly lower than the other two in children behavioral problems. However, the low regulation weak type and the general average type did not differ in children internalizing and externalizing behavioral problems. The results imply that early integrative intervention that helps alleviate maternal child-rearing stress and promotes mothers regulatory resources should be instated to mitigate young children behavioral problems.
