This study was conducted in order to find out protective factors on adolescent's social withdrawal. The purpose of this study was to test the mediator effects of adolescent's ego-resilience in the relation between affectionate parenting attitudes and adolescent's social withdrawal. The data were collected from 586 students of high schools located in 'D' city, Korea. Adolescents completed questionnaires on 'My Memories of Upbringing(EMBU-short)', ego-resilience, and 'Korean Youth Self Report(K-YSR)' scales. The correlation and structural equation model were conducted to examine the relations between the variables by using the SPSS 21.0 and AMOS 21.0. The results are as follow: First, while the affectionate parenting attitudes did not directly affect the adolescent's social withdrawal, the ego-resilience had a direct effect on the adolescent's social withdrawal. Second, there was a significant mediator effect of the adolescent's ego-resilience between the affectionate parenting attitude and adolescent's social withdrawal. In conclusion, these results can be used as basic data to prevent social withdrawal of adolescents and increase their ego-resilience.

Employee engagement plays an important role in the development as well as the success of a company. The manner in which employees are committed to their work and be more innovative seems to drive people's curiosity. This study aims to analyze the impacts of job demands-resources, personal resources, and coworker support on work engagement. Also, whether there is a relationship between work engagement and creativity of employees is tested through this research. The data served for the research was collected in the context of Vietnamese small- and medium-sized enterprises (SMEs). The authors used structural equation modeling (SEM) (software Smart PLS), to test the proposed hypotheses by using the data of 602 employees. Results of the study point out that proposed antecedents influence work engagement and creativity. Such findings have shed light on both theory and practice implications. In theory, it supports the social exchange theory and the job demands and resources model. In practice, leaders should assist subordinates in various aspects and build and promote a corporate culture where employees help others with great enthusiasm to increase the level of work engagement and spirit of innovation of employees.

The simple regression model (SRM) is used in this study to look at potential economic growth-influencing factors. The sample's period runs from 2005 to 2019. The data was gathered from various ministries and government agencies such as the Central Bank of Afghanistan's Statistical Bulletin, the World Bank, the United Nations (UN), World Bank open data, NASA, Ministry of Finance (MoF), Ministry of Economy (MoE), and Central Bank of Afghanistan's Statistical Bulletin (CBA), as well as the internet and news. There is an urgent need to ensure that taxes are collected in the most efficient manner possible because one of the enormous management gaps in Afghanistan over the last two decades has been tax evasion. According to the results of this study, tax evasion has a negative and significant impact on Afghanistan's economic growth. We can affirm that the subject of this article is among the most significant topics recently discussed in my country. If the right solutions are implemented, It can significantly contribute to quickening the cycle of the developing Afghan economy and turning it from an unstable to a sustainable one.

Antarctica is very sensitive to climate change but the number of stations is not sufficient to accurately analyze climate change in this regoin. Model reanalysis data supplements the lack of observation and can be used as long term data to verify climate change. In this study, the 20CR (Twentieth Century Reanalysis) Project data from NCEP/NCAR and monthly mean data (temperature, solar radiation and longwave radiation) from 1871 to 2008, was used to analyze the temperature trend and change in radiation. The 20CR data was used to validate the observation data from Antarctica since 1950 and the correlation coefficients between these data were determined to be over 0.95 at all stations. The temperature increased by approximately $0.23^{\circ}C$/decade during the study period and over $0.20^{\circ}C$/decade over all of the months. This increasing trend was observed throughout the Antarctica and a slight increase was observed in the Antarctic Peninsula. In addition, solar radiation (surface) and longwave radiation (surface and top of atmosphere) trends correlated with the increase in temperature. As a result, outgoing longwave radiation at the surface is attenuated by atmospheric water vapor or clouds and radiation at the top of the atmosphere was reduced. In addition, the absorbed energy in the atmosphere increases the temperature of the atmosphere and surface, and then the heated surface emits more longwave radiation. Eventually these processes are repeated in a positive feedback loop, which results in a continuous rise in temperature.

Objective: This study aimed to explore the usefulness of adjunctive buccal and palatal corticotomy for adult maxillary expansion in an animal model using cone-beam computed tomography (CBCT). Methods: Twelve adult sheep were randomly divided into two groups (each n = 6): a control group, where no treatment was administered, and a treatment group, where buccal and palatal corticotomy-assisted maxillary expansion was performed. CBCT scans were taken before (T1) and after (T2) treatment. Differences in all transverse dental and alveolar dimensions, alveolar width at crest level, hard palate level, horizontal bone loss, interdental cusp width and inter-root apex were assessed using Wilcoxon signed-rank and Mann-Whitney U-tests. Kruskal-Wallis tests and pairwise comparisons were used to detect the significance of differences among the inter-premolar and inter-molar widths. Results: CBCT data revealed significant changes in all transverse dental and alveolar dimensions. The mean interpremolar alveolar width showed an increase of 2.29 to 3.62 mm at the hard palate level, 3.89 to 4.38 mm at the alveolar crest level, and 9.17 to 10.42 mm at the buccal cusp level. Dental changes in the vertical dimension were not significant. Conclusions: Our findings based on an adult animal model suggest that adjunctive buccal and palatal corticotomy can allow for both skeletal and dental expansion, with the amount of dental expansion exceeding that of skeletal expansion at alveolar crest and hard palate levels by two and three folds, respectively. Therefore, this treatment modality is potential to enhance the outcomes of maxillary expansion in adults.

하천법에 의거하여 국내 하천들에는 상당한 국가예산으로 하천정비기본계획이 5-10년 주기로 수립되고 있으며, 홍수위 계산을 위한 HEC-RAS 모의에 필요한 하천단면 등 다양한 하천측량이 실시되고 있다. 그러나, 하천측량자료들은 하천관리지리정보시스템(RIMGIS)에 pdf 보고서 형태로만 제공되고, 원자료는 CAD 형식으로 하천정비계획을 수행한 설계사 등이 분산 소유하고 있어 관리 부재로 망실의 우려도 있어, 다른 용도로의 활용성이 상당히 저하되어 있는 실정이다. 그리고, 측량된 CAD 형식의 단면자료 등을 HEC-RAS에 활용할 때, 'Dream'과 같은 툴을 활용하나 거의 수작업에 가까운 시간과 비용이 소요되는 현실에 있다. 본 연구에서는 이러한 문제들을 해결할 수 있는 툴인 RAUT(River information Auto Upload Tool)를 개발하였다. RAUT 툴은 첫째, 실무에서 하천기본계획 수립 시 활용되는 HEC-RAS 1차원 모형의 입력자료를 CAD 측량자료를 직접 수기로 입력 및 모의를 실시하는 복잡한 단계를 자동화시키고자 하였다. 둘째, 하천공간정보인 CAD측량 자료를 직접 읽어 표준 데이터 모델 (ArcRiver)기반 하천공간정보 DB에 자동 업로드하여 전국단위의 하천정비계획의 하천측량자료 관리가 가능하게 할 수 있다. 즉, 만약 RIMGIS가 RAUT와 같은 툴을 사용하면 하천단면과 같은 전국단위 하천측량 자료를 체계적으로 관리할 수 있게 된다는 의미이다. 개발한 RAUT는 제주도 한천유역을 대상으로 하천정비기본계획의 하천공간정보 CAD자료를 읽어들여 mySQL기반 공간 DB로 구축하고, 구축된 DB로부터 HEC-RAS 1차원 모의 실시하기 위한 지형자료를 자동으로 생성시키는 과정을 시범적으로 구현하였다.
