In Korea, rural groundwater development faces new challenge, which have not been experienced so far. The problem is a groundwater depletion by the water curtain cultivation (WCC) during winter season. This study investigates the groundwater depletion using three-dimensional finite difference groundwater flow program, MODFLOW to verify the water budget of the shallow aquifer of Cheongweon area. Interdisciplinary research, which has become a worldwide trend, has been adopted in studying groundwater modeling in field scale. In particular, the method of groundwater recharge estimation adopted precise modeling techniques, SWAT to groundwater flow modeling. Based on qualified field data, the model calibrated and validated its reliability. The objective of this study is to simulate various stream-aquifer interactions according to groundwater pumping with artificial boundaries, such as weirs and drainage system. We also analyzed a seasonal variation of cumulative water budget of the site to quantify the groundwater depletion and recovery in the pumping field.

This study attempts to simulate the structure of a woody leaf netted venation system by using topology optimization techniques. Based on finite element method (FEM) analysis of an incompressible fluid, a topology optimal design is applied to those woody leaf netted venation models. To solve the transverse shear locking problem of a thin plate caused by the Mindlin-Reissner plate model where a leaf netted venation is assumed to be a thin plate, a P1-nonconforming element and selective reduced integration are employed. Topology optimal design is applied to multiple physical domains. Combined with the Darcy-Stokes flow problems and extended to the optimal design of fluid channels, the multiple physical models of the flow system are analyzed and venation patterns of leafs are simulated. The calculated optimal shapes are compared with the natural shapes of woody leaf venation patterns. This interdisciplinary approach may improve our understanding of the leaf venation system.

In the contemporary modern society, information and knowledge generate a set of new social values. These changes demand a transformation not only in socio-cultural and educational spheres, but also, specifically, in the field of culture and art education. Culture and Art education emphasizes the integration and cross-discipline of other related fields which have great impact on culture and arts. This study applies theoretical analysis of Animation education in the context of culture and art education. Animation education takes an interdisciplinary approach to integrate various subjects in the field of culture and art education. Animation, as a form of culture and art education, plays an educational role in the social classroom. Animation education should be developed and expanded to become a regular classroom course. The goal of Animation education is to pursue and develop a connection with other educational courses of study. In order to strengthen the role of Animation education, we should first re-structure the pedagogical role of Animation education. Secondly, Animation education needs to become a diversified and popularized education. Third, the cultivation of creative human resources is considered of vital importance to Animation education.

This research was designed to verify the causal relationships between organization managers' unmet expectations and job burnout and the mediating effects of overcommitment based on the effort-rewards imbalance theory. It was also intended to evaluate the moderating effect of LMXSC on the relationship between overcommitment and job burnout. 172 branch managers working at commercial bank were selected as the target research group. This study was validated by The SPSS 24.0, the reliability was justified through the factor analysis, and the casual relationship was confirmed through the three-step regression. As a result, unmet expectations had a strong positive correlation with job burnout and overcommitment. Overcommitment had a strong positive correlation with the mediating effect between unmet expectations and job burnout. Moderating effects of LMXSC were not significant. This study showed the practical implication between unmet expectations, overcommitment, and job burnout. Additionally it exhibited the job design and management practice in manager groups where the importance of their role has been expanded. Lastly, we found the interdisciplinary implication from making an effort to elaborate the antecedent of variables.

Flora of the Dokdo Islet, where located south-east from Ulnung Island, off the east coast of the Korean peninsula, recorded as 59 taxa; 29 families, 50 genus, 48 species, 1 sub-species, 9 varieties and 1 form. Dong-do (East islet) of Dokdo Islet, naturalized plants such as Brassica campestris subsp. napus var. nipp-oleitera and Rumex crispus are widely ranged over the islet. The naturalizedplants affects the native species and their habitats of Artemisia japonica var. macrocephala, Echinochloa crus-galli, Sedum oryzifolium, Arabis stelleri var. japonica and Sedum kamtschaticum var takesimense in the islet. The trail in Seo-do (West islet) is heavily threatened by over-all weathering processes on the rock. The native woody species in the islet are Euonymous japonicus and Lonicera insularis, and the species such as Pinus thunbergii and Hibiscus syriacus are planted in the recent past under the IRP (Islet Restoration Program) by NGO.

This study was to find out the influence of smoking behavior in Korean adults on chronic diseases using data from the seventh Korea national health and nutrition examination survey(KNHANES VII-2) 2017. The subjects were 6,193. The data were analyzed by frequency analysis, x² test and logistic regression analysis using SPSS 25 complex samples Win program. The main findings were that smoking age and smoking behavior were considered as early as the age of smoking, and in case of smoking in the past, the prevalence of chronic disease increased 1.30 times and 2.75 times, respectively. When the subjects' health behaviors and demographic characteristics were simultaneously corrected, the higher the age was, the more they were 0.25 times higher and 0.34 times higher than the graduate level of education. As a result, it is necessary to improve lifestyles such as obesity and lack of exercise, to reduce the prevalence of chronic disease in Korean adults, and to pay attention to younger age groups. There is a need to develop interdisciplinary convergent approaches with great interest.

This study was attempted to understand the effect of the violence victim experience of Korean adolescents on smoking using the data of the 15th (2019) online youth health behavior survey. The subjects of this study were 57,303 people, and the data were analyzed using the SPSS / Win 26.0 program for frequency analysis of complex samples, cross sample analysis (Rao-Scott ��2 test), and logistic regression analysis of complex samples. The main result was 12.7% of the smoking subjects. Those who smoked were significantly more 9.6% and 22.0%, respectively, compared to those who had no more than 1 or 2 times of violence. Smoking of Korean adolescents adjusted for gender, grade, academic record, economic status, drinking, family living, and usual stress increased the odds ratio for smoking by 1.66 times when the degree of violence damage experience increased by 1 unit. As a result of the above, as the degree of violence victimization of adolescents increases, the likelihood of smoking increases. Therefore, it is necessary to multidisciplinary convergence effort to the prevention and management of violence of adolescents, and to reduce the smoking of adolescents.

Congenitally missing teeth are one of the most prevalent dental anomalies in the oral cavity. In this study, the prevalence, distribution, and symmetry of congenitally missing permanent teeth among 1,865 patients aged 7 to 15 years who visited the Pediatric Dentistry Department of Wonju Severance Christian Hospital from March 2011 to May 2021 and took panoramic radiographs were investigated and analyzed. Most of the patients had one or two congenitally missing teeth, mainly in the second premolars and lateral incisors. Congenitally missing teeth occurred more in the mandible than in the maxilla, and there was no significant difference in prevalence between the left and right sides. Congenitally missing teeth tend to occur symmetrically on the left and right sides and in the maxilla and mandible, depending on the tooth. Early oral examination and radiological examination are required to prevent complications due to congenitally missing teeth, and appropriate interdisciplinary treatment is required.
