본 논문은 스마트 교육을 위한 청소년의 우울과 휴대폰 의존도, 부모의 양육행동, 또래관계의 구조적 관계를 확인하고자 하였다. 또 청소년의 우울과 휴대폰 의존 관계에서 부모양육행동과 또래관계의 매개적 효과를 확인하였다. 본 연구는 한국아동, 청소년패널 조사(KCYPS) 6차년도 중1패널의 자료 중 총 1897명의 청소년 응답과 보호자의 설문데이터를 분석대상으로 하였다. 자료분석을 위해 SPSS와 Amos프로그램을 사용하였다. 대상 변인들의 상관 및 기술통계분석을 위해서 SPSS을 사용하였고 부모의 양육행동의 경로분석과 매개효과 검증을 위해 구조방정식을 이용하였다. 검증결과, 청소년의 우울과 부모의 양육행동은 청소년의 휴대폰 의존도에 직접적인 영향을 미치는 것으로 나타났다. 그리고 청소년의 우울은 부모의 양육행동을 통해 간접적인 영향을 미치는 것으로 나타나 부분 매개효과를 확인할 수 있었다. 하지만 또래관계의 매개효과는 나타나지 않았다. 이상의 결과로부터 청소년의 휴대전화 의존을 예방하기 위한 방안과 스마트 교육 개발시 유의점에 등에 대해 논의하였다.

Solar-sharing, which is an agricultural photovoltaic system installing solar panels on the upper part of crop growing field, has especially drawn attention. Because paddy fields for cultivating crops are large flat areas, there have been various attempts to utilize solar energy for solar photovoltaic as well as growth of crops in agriculture. Solar-sharing was first proposed in Japan, and has been actively studied for optimization and practical uses. The domestic climate differs from the climate conditions in which the solar-sharing has been widely studied, therefore, it is required to develop the solar-sharing technology suitable for the domestic climate. In this study, a simulation model was developed to analyze the change of solar radiation resulted from the solar-sharing installation. Monthly solar illumination intensity and the change of illumination intensity according to the various conditions of solar panel installation were simulated. The results of monthly illumination analysis differed by altitude of the sun, which was related to season. In addition, it was analyzed that the monthly illumination decreased by up to 42% due to solar-sharing. Accordingly, it is recommended that solar-sharing should be installed as a way to maximize the efficiency of solar photovoltaic system while minimizing the decrease in solar radiation reaching the crops.

본 연구는 청소년의 학업무기력에 영향을 미치는 우울, 자아존중감 및 사회적 위축의 구조적 관계를 알아보기 위해 수행되었다. 한국아동·청소년패널조사 2018의 중 1패널의 제4차 년도(2021년) 자료를 이용하였으며, 대상자는 고등학교 1학년 2,265명이었다. 본 연구에서 자료는 SmartPLS 3.0을 이용하여 부분최소제곱법 기반의 구조방정식모형을 통해 분석되었다. 분석 결과, 청소년의 학업무기력에 우울과 사회적 위축은 유의한 정적 영향을 주었으며, 자아존중감은 유의한 부적 영향을 주었다. 또한 우울과 학업무기력 간의 관계에서 사회적 위축은 유의한 정적 매개영향을 주었다. 그러므로 청소년의 학업 무기력에 대한 접근 시 우울, 자아존중감 및 사회적 위축과의 영향 관계를 고려한 전략이 요구된다.

Objectives : The purpose of this study was to analyze the relationships among social participation, self-rated health status, self-esteem and daily life satisfaction of the elderly with disabilities. It especially focused on the mediating effects of self-rated health status and self-esteem on the relationship between social participation and daily life satisfaction. Methods : From the fifth panel survey of employment for the disabled, data for 518 elderly over age of 65 were analyzed with SPSS 22.0, SmartPLS 2.0 M3 and the Sobel test. Results : First, social participation of the elderly with disabilities had a positive influence on the self-rated health status and self-esteem. The direct effect of self-rated health status and self-esteem on daily life satisfaction was statistically significant. However, the influence of social participation on daily life satisfaction was not statistically significant. Second, the self-rated health status and self-esteem had a mediating effect on the relationship between social participation and daily life satisfaction. Conclusions : This study shows that it is important to provide an integrated social participation support program that coincides with a variety of social programs to elderly with disabilities.

The purpose of this research is to organize panels centered on professional workers and experts in the sports media industry, identify structures and items of sports media commentators' attributes that conform to the present era through the collective agreement process, and evaluate the derived measures according to the scale development procedure. We would like to shed new light on the nature of commentators due to the rapid development of broadcasting technology and the emergence of new media platforms, the emergence and expansion of smart media receptors and the changing environment of modern sports broadcasting. For this purpose, a panel of experts from academia and industry related to sports management and sports media was organized and the attributes of commentators were analyzed using the Delphi method. Technology development in the sports market has created a new sports consumption environment. In these consumer environments, various environmental factors influence the consumer's consumption culture of sports consumers. For example, professional information, as well as interpretations of sports culture, history and society are becoming their share for sports commentators, and viewers are demanding more diverse characteristics from sports commentators. In this respect, the study of sports commentator attributes can be a deep understanding of the rapidly changing culture of sports consumption.

This study analyzed the current state of art by investigating related patents of cycling wear, and suggested fundamental data to develop clothing - originated in Korea. Patent trends were then analyzed after the related patents applied in Korea, USA, and Japan from 1975 to 2015 were extracted using WIPS ON, classified as nation, applicant, technology, use, and technological maturity of the applicant country. The number of patent applications has steadily increased since the 1990s, and has steeply grown since the 2000s. The USA accounted for 55.6% of all collected patents in the study, Japan for 30.6%, and Korea for 13.7%. Technologies related to patterns and functional materials have been dominated by the USA and Japan; however, smart technologies have been actively developed in Korea. According to use, USA focused on functionality, Korea concentrated on safety, and Japan uniformly combined functionality, safety, and convenience. According to the positioning of technology by application, water repellency, stretchability, muscle strengthening, pad, panel, finishing, and weaving technologies were positioned in the functionality.

Damage detection methods based on modal analysis have been widely studied in recent years. However the calculation of mode shapes in real structures can be time consuming and often requires dedicated software programmes. In the present paper the combined application of proper orthogonal decomposition and gapped smoothing method to structural damage detection is presented. The first is used to calculate the dynamic shapes of a damaged structural element using only the time response of the system while the second is used to derive a reference baseline to which compare the data coming from the damaged structure. Experimental verification is provided for a beam case while numerical analyses are conducted on plates. The introduction of a stiffener on a plate is investigated and a method to distinguish its influence from that of a defect is presented. Results highlight that the derivatives of the proper orthogonal modes are more effective damage indices than the modes themselves and that they can be used in damage detection when only data from the damaged structure are available. Furthermore the stiffened plate case shows how the simple use of the curvature is not sufficient when analysing complex components. The combined application of the two techniques provides a possible improvement in damage detection of typical aeronautical structures.

Sub-station, key equipment in electric power infrastructure, are being exposed to increasing risk of hacking. For this, soft redundancy sub-station system needs to be formulated with automatic restoration mechanism. For this it is important to assess the reliability of the applicable range of data that are used in actual system operation, as well as the methods and findings of the tests. At the same time performance of soft redundancy system and total security mechanism, which are aligned for the protection of the sub-station, need to be tested. For testing the above-mentioned, this paper presented a viable formation of a soft redundancy practical VPN system within a panel to protect the latter from hacking or cracking incidences, and conducts a test to check if the considered system actually serves the protection function in the actual operation setting, gathering evidence from the data from the testing of the actual performance of the system as well as of emergency scenario simulation operations. Because tested soft-redundancy & restorative sub-station system is expected to be widely applicable for various cases such as Smart-grid or electricity IT system, where VPN with enhanced level of security is required.
