박지선 한국건강심리학회 2013 한국심리학회지 건강 Vol.18 No.4

The purpose of the present study is to confirm psychometric properties of the Difficulties in Emotion Regulation Scale in Korean adolescents. In order to examine this, the Korean Version Emotion Dysregulation Sclae, ERQ-CA, ERAS, ERCL, TMMS, K-YSR were administered to 1067 middle and high school students in Pusan. Finally reposes from 998 students were used for the analysis. In result, the results of exploratory factor analysis of the DERS in Korean adolescents revealed 6 factor structure: Nonacceptance, Impuse, Awareness, Strategies, Goals, Clarity. Also internal consistencies and test-retest reliabilities of six subscales of the DERS in Korean adolescents were considered to an acceptable level. To test the convergent validity of K-CTQ, correlation analyses were conducted with the ERQ-CA, ERAS, ERCL, TTMS. Most of the DERS subscales was significantly correlated with corresponding the other emotion regulation subscales. The results of correlation and Oneway ANOVA between the DERS and the YSR showed that the DERS was associated with internalized and externalized problem. The results support the DERS in Korean adolescents is a reliable and valid scale. Finally, the importance of emotion regulation of adolescents was discussed. Also the limitations of the present study and suggestions for the future research were discussed. 현 연구의 주목적은 청소년을 대상으로 정서조절곤란척도의 심리측정적 속성을 검증하는 것이다. 이를 위해 부산시에 위치한 중․고등학교 학생 1067명에게 정서조절곤란척도(DERS), 정서조절능력척도(ERAS), 정서조절체크리스트(ERCL), 특질-상위기분척도(TTMS), 한국판 청소년자기행동평가척도(K-YSR)를 실시하였다. 불성실한 응답을 제외한 998명의 자료가 분석에 사용되었는데 한국판 청소년용 DERS는 비수용, 충동, 자각, 전략, 목표, 명확성이라는 6개의 요인구조를 지니고 있는 것으로 확인되었다. 6가지 하위 요인의 내적합치도와 검사-재검사 신뢰도는 만족할만한 수준에 해당하였다. 한국판 청소년용 DERS의 수렴 타당도를 검증하기 위해 다른 정서조절척도와의 상관관계를 조사한 결과, 한국판 청소년용 DERS는 다른 정서조절척도와 대부분 유의미한 상관을 보였다. 한국판 청소년용 DERS와 정신건강과의 관계를 알아보기 위해 K-YSR과의 상관을 분석한 결과, 한국판 청소년용 DERS와 K-YSR의 하위 요인들이 모두 유의미한 정적 상관을 보였다. 마지막으로 K-YSR의 임상범위에 해당하는 점수를 토대로 내재화문제, 외현화문제 집단으로 구분한 후 정상집단과의 평균을 비교한 결과 내재화문제는 한국판 청소년용 DERS의 모든 하위척도와, 외현화문제는 정서자각관련 하위요인을 제외한 모든 하위요인과 유의미한 점수차를 보여 청소년의 정서조절곤란이 심리적 부적응과 관련이 있음을 보여 주었다. 마지막으로 청소년 시기의 정서조절의 중요성과 현 연구의 제한점, 향후 연구를 위한 제안점을 논하였다.

정서조절곤란의 평가: 한국판 척도의 심리측정적 속성

조용래 한국임상심리학회 2007 Korean Journal of Clinical Psychology Vol.26 No.4

There is an increasing attention to the importance of emotion dysregulation in the development, maintenance, and treatment of mental disorders. This article described two studies examining the psychometric properties of a Korean version of the Difficulties in Emotion Regulation Scale(DERS) recently developed to comprehensively assess emotion dysregulation among adults. In Study 1, the results of factor analyses of the K-DERS revealed a six-factor solution - “impulse control difficulties,” “lack of attention to and awareness of emotions,” “nonacceptance of emotions,” “lack of emotional clarity,” “limited access to emotion regulation strategies,” and “difficulties in engaging in goal-directed behavior”, respectively. In Study 2, the six-factor structure was largely replicated in an independent sample. In addition, the results revealed high internal consistency, adequate test-retest reliability over a two-week period, good convergent, discriminant, criterion-related, and incremental validity of the K-DERS. In conclusion, these findings suggest that the K-DERS is a highly reliable, valid measure to assess general and specific aspects of emotion dysregulation.

정서조절방략이 정서조절곤란에 미치는 영향

이지영 한국상담심리학회 2010 한국심리학회지 상담 및 심리치료 Vol.22 No.3

This study aimed to investigate the relation between the emotion regulation strategies and the emotion dysregulation as well as and the effects of the emotion regulation strategies on the emotion dysregulation. For this purpose, Emotion Regulation Strategy Questionnaire (ERSQ) and Difficulties in Emotion Regulation Scale (DERS) were implemented to 214 undergraduate students to measure the emotion regulation strategies and the emotion dysregulation, respectively. Correlational analysis indicated that maladaptive strategies were positively correlated with the emotion dysregulation and distractive strategies and approaching strategies among adaptive strategies were negatively correlated with the emotion dysregulation. Results of multiple regression analysis showed that the emotion regulation strategies accounted for 39% of the variance in the emotion dysregulation. The maladaptive strategies exhibited the highest predictive power for the emotion dysregulation. In addition, among adaptive strategies only approaching strategies were significant predictors of the emotion dysregulation. Implications and suggestions for future research are discussed. 본 연구는 정서조절방략과 정서조절곤란 간의 관계를 조사하고, 정서조절방략들이 정서조절곤란에 미치는 영향을 경험적으로 확인하고자 하였다. 이를 위해 대학생 집단을 대상으로 다양한 정서조절방략을 포괄적으로 측정 및 구분하는 정서조절방략 질문지(ERSQ)와 정서조절곤란 수준을 포괄적으로 평가하는 정서조절곤란 척도(DERS)를 실시하였다. 먼저 상관분석을 실시한 결과, 부적응적 정서조절방략은 정서조절곤란 총점과 유의미한 정적 상관을 보였다. 적응적 정서조절방략들 중에서 주의 분산적 방략과 접근적 방략이 정서조절곤란 총점과 유의미한 부적 상관을 나타냈고, 지지 추구적 방략은 정서조절곤란과 유의미한 상관을 보이지 않았다. 다양한 정서조절방략들이 정서조절곤란의 수준에 미치는 영향을 조사하기 위해 중다회귀분석을 실시한 결과, 정서조절방략들에 의해 정서조절곤란을 설명하는 모델은 통계적으로 유의미하였고, 정서조절방략들은 정서조절곤란의 전체 변량 가운데 39%를 설명하였다. 정서조절방략들 가운데 부적응적 정서조절방략이 정서조절곤란에 대한 가장 높은 예측력을 보였고, 적응적 방략들 중에서는 접근적 방략만이 정서조절곤란을 통계적으로 유의미하게 예언하였다. 본 연구의 시사점과 앞으로의 연구 방향에 대해 논의하였다.

A New Approach for Corrective and Preventive Control to Unsolvable Case in Power Networks having DERs

Hung Nguyen Dinh,Minh Y Nguyen 대한전기학회 2013 Journal of Electrical Engineering & Technology Vol.8 No.3

Recently, Korean system operating conditions have gradually approached an upper limit. When a contingency occurs, the power system may have no solutions. Different from the cases of bad initial guesses or the solutions are too close to the solvability boundary in which numerical methods can be applied, for unsolvable cases, the only way to restore solvability would be structure modifications. In this paper, a new approach for corrective and preventive control to such cases is proposed in two steps: (i) finding any solution regardless its feasibility; (ii) for the infeasible solution, make it feasible with additional modifications at load buses having Distributed Energy Resources. The test case built based on the peak load profile of 2008 by KEPCO including 1336 buses is analyzed. Since reactive power compensation is optimized to restore solvability, all demands are met, therefore no blackouts happen. The proposed method was integrated in the LP program designed by power21 Corporation.

Recently, DC microgrids with DERs are emerging for efficient distributed power design and operation. However, protection standards have not yet been established, and it is urgent to prepare a protection solution that can supply high-quality power. To develop speedy and reliable fault detection, this paper proposes a fault detection method using WBE (Wavelet-based Energy) for a DC microgrid. The target DC microgrid is a domestic 1500Vdc (±750Vdc) radial system composed of PV, BESS, and DC loads, and was modeled using PSCAD platform. In addition, the conventional ICCR (instantaneous current change rate) method and the proposed WBE method were implemented using the MATLAB tool, and the performances of detecting PtoP (pole to pole) and PtoG (pole to ground) faults were verified through various faults analysis.

DC 마이크로그리드의 취약 모선 제어를 위한 정적 전압 제어시스템

최윤혁 한국조명.전기설비학회 2022 조명·전기설비학회논문지 Vol.36 No.7

As distributed energy resources (DERs) and power electronic loads are connected to the distribution grid, a DC power distribution system is becoming serious problems which are arc according to AC/DC converter switching and are protection devices. In particular, while an AC system has problems such as frequency, reactive power, and power factor, voltage control is the most important problem in the DC power distribution system. Therefore, in this paper, a voltage control method of the DC power distribution system is proposed based on the concept of integer programming, which is evaluated by the cost function and sensitivity calculation of various energy resources. The effectiveness of the proposed method was verified by conducting a simulation on the vulnerable bus in the DC power distribution system.

Microgrid is a small-scale power system composed of distributed generators, energy storage system and loads, and can operate in the grid-connected mode and the islanded mode. This paper presents optimal design procedures for remote microgrid. The design program is based on the economic evaluations including the feasibility study module, optimal combination and allocation of DERs, power network design and the reduction of the GHG emmission. This program which is suggested in this paper shows good performance as a tool of remote microgrid design.

SERRATION MECHANISM OF AA5182/POLYPROPYLENE/AA5182 SANDWICH SHEETS

Kim, K.J. The Korean Society of Automotive Engineers 2006 International journal of automotive technology Vol.7 No.4

The AA5182/polypropylene/AA5182(AA/PP/AA) sandwich sheets have been developed for application to automotive body panels in future lightweight vehicles with significant weight reduction. It has been reported that the AA5182 aluminum sheet shows $L\"{u}ders$ band because of dissolved Mg atoms that cause fabrication process problem, especially surface roughness. The examination of serration behavior has been made after the tensile deformation of the AA/PP/AA sandwich sheets as well as that of the AA5182 aluminum skins at room and elevated temperatures. All sandwich sheets and the AA5182 aluminum skin showed serration behavior on their flow curves. However, the magnitude of serration was significantly diminished in the sandwich sheet with high volume fraction of the polypropylene core. According to the results of the analysis of the surface roughness following the tensile test, $L\"{u}ders$ band depth of the sandwich sheet evidently showed lower than that of the AA5182 aluminum skin. The strain rate sensitivity, m-value, of the AA5182 aluminum skin was -0.006. By attaching these skins to the polypropylene core, which has relatively large positive value of 0.050, m-value of the sandwich sheets changed to the positive value. The serration mechanism of the sandwich sheets was quantitatively investigated in the point of the effect on polypropylene thickness variation, that on the strain rate sensitivity and that on the localized stress state.
