  • Macroinvertebrates in forest streams affect the overall health of other streams in the same water system. In this study, we compared differences in the benthic macroinvertebrate community at two headwater streams located at different latitudes in the southern and northern parts of South Korea. We calculated the community temperature index (CTI), which represents the thermal preferences of the benthic communities. Hierarchical cluster analyses (HCA) were conducted to compare the similarities among sampling sites. In addition, we analyzed the relationship between community composition and environmental and community characteristics using non-metric multidimensional scaling (NMDS). Our results showed that CTI was significantly different between the two regions, indicating that these benthic macroinvertebrate communities have different thermal preferences. These two regions were clearly distinguished from each other in the HCA; furthermore, seasonal differences in benthic community composition were observed within each region. The functional feeding groups present in the benthic macroinvertebrate communities were different even though their habitat was similar.

  • This study assumes that the smooth school life of adolescents from multicultural families is recognized as an important part of multicultural support policies and practices as a basis for realizing an integrated society, and system elements that are meaningful for their flexibility to adapt to school (individuals, families, schools) By empirically analyzing the effect of, we tried to bring out highly effective implications for the composition of a multidimensional practice system. Therefore, this study is a causal model in which self-identity (individual factor) and parental parenting attitude (family factor), which are important variables for each system level, are set as independent variables, and school support (school factor) consisting of teacher support and companion support is set as control variables. After collecting data through a questionnaire survey by interviews with 162 middle and high school students in Gyeonggi and Gangwon regions, the effect was analyzed through multiple regression analysis. As a result of the analysis, it was confirmed that school support has a very important static moderating effect in the positive (+) effect of adolescents' self-identity and parenting attitude on school adaptability. It was confirmed that the modulating effect is relatively more important.

  • As the online education market expands, educational contents with various presentation methods are being developed and released. In addition, it is imperative to develop content that reflects the usability and user environment of users who use this educational content. However, for qualitative growth of contents that will support quantitative expansion of markets, existing model analysis methods are urgently needed at a time when development direction of newly developed contents is secured. In this process of content development, a typical model for setting development goals is needed, as the rules of the prototype affect the entire development process and the final development outcome. It can also provide a positive benefit that screens the issue of performance dualization between processes due to the absence of communication between a single entity or between a number of entities. In the case of AR-based educational content which is effective to secure data necessary for development by securing samples of similar categories because there are not enough ready-made samples released. Therefore, a big data statistical analysis service is needed that can easily collect data and make decisions using big data. In this paper, we would like to design analysis services that enable the selection and detection of intuitive multidimensional factors and attributes, and propose big data-based statistical analysis services that can assist cooperative activities within an organization or among many companies.

  • Recently, the rapid proliferation, introduction, and application of the fourth industrial revolution technology has emerged as a trend in the construction market. Building Information Model (BIM) technology is a multidimensional information system that forms the basis of the fourth industrial revolution technology. The river sector utilizing this information-based system is also being actively reviewed, for example, the current measures for maintenance. In recent years, active research and current work should be done to reflect the need for river experts to introduce BIM into the river field. In addition, the development of tools and support software for establishing various information systems is essential for the activation of facility maintenance information systems reflecting advanced technology and to establish and operate management plans. A study on the maintenance of river facilities involves using existing drawings to build a three-dimensional (3D) information model, check the damage utilizing it, and inform it, and utilize it as the data for maintenance reinforcement. This study involved determining a method to build a river facility without the existing information system and using the property maintenance information with 3D modeling to provide a more effective and highly utilized management plan to check maintenance operations and manage damages.

  • This study aimed to identify the effects of adolescents' self-perceived health on their life satisfaction and verify the mediating effects of the relationship between the two factors. The analysis was conducted using the Korean Children and Youth Panel Study (KCYPS, Ed. 6), and the results are as follows. In terms of the factors, the mean value of the adolescents' self-perceived health was 3.13, which was regarded as a moderate level, while the values of life satisfaction and self-esteem were 2.80 and 2.90, respectively, which were regarded as low levels. An analysis of the study model showed that the adolescents' self-perceived health affected their life satisfaction, and self-esteem played a meditating role in such a relationship. In other words, a higher level of self-perceived health would help improve self-esteem, which would promote a level of life-satisfaction. Therefore, this study has implications that healthcare or psychological/ emotional resources have been identified to influence adolescents' life satisfaction. Furthermore, multidimensional interventions are needed to reinforce the individuals' psychological and develop emotional resources in healthcare or welfare fields. Moreover, efforts are needed to enhance the adolescents' self-perceived health that would affect their life satisfaction.

  • This study attempted to examine the role of gender roles in psychological distress of Korean adult men. Specifically, it was attempted to verify whether compliance with multidimensional male gender roles predicts psychological distress through gender role conflict. To this end, this study was conducted on 358 male participants aged 19 to 39 using the Korean Conformity to Masculine Norm Inventory, Korean Male Gender Role Conflict Scale, and General Health Questionnaire. As a result of the study, it was found that the influence on psychological distress through male gender role conflict was different depending on the sub-factors of the male gender norm. The sub-factors of masculine norms, 'power and control', 'job - independence', and 'emotion suppression', were statically predicted psychological distress through the medium of 'fear for femininity', which is a sub-factor of gender role conflict. Meanwhile, among the male norms, 'male leadership' and 'family support' had negative direct effects on psychological distress, and the indirect effects through gender role conflict were not significant. The results of this study suggest that the sub-factors of male norms have different functions for psychological distress, and in particular, the dysfunctional role of male norms can be caused by negative emotions about femininity during gender role conflict.

  • This study focused on the heterogeneity of groups in single-person households, to identify how middle-aged single-person households is categorized by sub-groups and to come up with policy measures to overcome social exclusion by examining predictive factors for the type of social exclusion. Potential class analysis and multinomial logistic regression analysis were conducted on a total of 361 middle-aged single-person households using the 14th Korea Replication Panel data. The social exclusion index of these households was measured consisting of 10 six-dimensional indicators. The results showed that middle-aged single-person households had five different types: "non-exclusion"(29.6%), "health restriction"(14.3%), "interact restriction and middle-risk multiple-exclusion" (12.0%), "income and health exclusion"(14.1%), and "high-risk multiple-exclusion"(30.0%). More than 70% of the respondents experienced social exclusion, and most of the exclusion types were multiple exclusion. When examining the factors affecting each exclusion type, the 'subjective health level' was a common major predictor, and family interact, age and leisure activity satisfaction variables were significant predictors of the 'high-risk multiple exclusion type' and 'the interact restriction and middle-risk multiple-exclusion type'. Based on these results, a multidimensional intervention strategy is an effective measure to solve the social exclusion problem of middle-aged single-person households, and practical measures should be considered by strengthening 'health' and exchanges.

  • This study was conducted to verify the effects of socially prescribed perfectionism on depression as mediated by intolerance of uncertainty and either ruminating or reflective response styles, on as will as to find ways to effectively address depression as it presents in university students. For this purpose, 283 university students at the central region were assesed using data collected from the following surveys: the Center for Epidemiological Studies-Depression Scale(CES-D), the Multidimensional Perfectionism Scale(HMPS), the Intolerance of Uncertainty Scale(IUS), and the Response to Depressed Mood Questionnaire(RDQ) and that were used to collect data. The results of this study are as follows. First, there was a positive correlation between the Intolerance of uncertainty and the rumination response style to the uncertainty of socially prescribed perfectionism, but not correlation the reflective response mode. Second, with respect to the relationship between socially prescribed perfectionism and depression, intolerance of uncertainty was set as the primary mediator variable and the rumination response style were set as the secondary mediator variables. The results shown to have a significant mediating effects. However this mediating effect was not significant when, in order to verify the mediating effect, we set the secondary mediator variable as the reflective response style. These results suggest that to prevent depression that manifests as socially prescribed perfectionism, it may be effective to intervene with a focus on the intolerance of uncertainty and the rumination response style. Finally, the implications and limitations of the study are discussed based on the results.

  • This study aims to validate the Korean Student Career Construction Inventory, a translated measure of career adaptation responses, with Korean college students. In order to do so, this study examines the relevant factor structure, internal consistency, test-retest reliability, criterion-related validity and measurement invariance between Korean undergraduate and graduate students. An online survey was completed by 294 participants, including the questions from the translated Korean Student Career Construction Inventory, in addition to measures of career adaptability and vocational identity. One hundred twenty five among the initial participants were tested again in three months for the examination of test-retest reliability. The results supported the four-factor structure of 18 items suggested by the original measure, as well as measurement invariance. The internal consistency and test-retest reliability were adequate. The Korean Student Career Construction Inventory was positively correlated with career adaptability, unidimensional vocational identity, and the dimensions of exploration and commitment of multidimensional vocational identity, but negatively with the dimension of reconsideration. The findings indicate that the Korean Student Career Construction Inventory has psychometric properties similar to the original form and can be used for both undergraduate and graduate students.
