본 연구는 유아기 자녀를 둔 부모를 대상으로 부모의 원가족경험이 양육행동에 미치는 영향에서 자아존중감의 매개효과를 검증하기 위하여 서울, 인천 등 수도권 지역에 거주하고 있는 만 3세∼만 5세의 유아기 자녀를 둔 부모 711명을 대상으로 SPSS 24.0와 LISREL 8.52를 활용하여 분석하였다. 원가족경험, 자아존중감, 양육행동간 관계를 파악하기 위해 Pearson의 적률상관분석을 실시하였고 원가족경험과 자아존중감이 양육행동에 미치는 영향에 관한 연구모형 검증을 위해 구조방정식모형을 분석하고, 연구모형의 타당성 검증을 위해 모형적합도 검증을 실시하였다. 연구결과는 다음과 같다. 첫째, 원가족경험이 양육행동에 미치는 영향은 가족투사, 정서적 단절, 가족퇴행이 양육행동에 부적 영향을 미치는 것으로 나타났다. 둘째, 원가족경험이 자아존중감에 미치는 영향은 가족투사와 정서적 단절이 자아존중감에 부적 영향을 미치는 것으로 나타났다. 셋째, 자아존중감이 양육행동에 미치는 영향은 판단과 행동, 자신의 가치가 양육행동에 정적인 영향을 미치는 것으로 나타났다. 마지막으로 자아존중감은 원가족경험과 양육행동에 부분매개 역할을 하는 것으로 나타났다. 본 연구는 부모의 원가족경험이 양육행동에 미치는 영향에 있어 부모의 자아존중감은 주요 매개변수임을 확인하였다. 미래사회의 부모역할 위기에 적절한 대처방안으로 부모교육 프로그램이나 상담을 위한 기초자료를 제공하는데 의의가 있다. This study was conducted to examine the mediating effect of self-esteem in the effects of family-of-origin experiences on parenting behavior for parents with children of infancy. SPSS 24.0 and LISREL 8.52 were used for data analysis of 711 parents with infant children. Pearson s moment correlation analysis was performed to understand the relationship between family-of-origin experience, self-esteem, and parenting behavior. Structural equation model was analyzed and researched to verify the research model on the effect of family-of-origin experience and self-esteem on parenting behavior. To verify the validity of the model, the model fit test was performed. The research results are as follows. First, as for the effect of family-of-origin experience on parenting behavior, it was found that family projection, emotional disconnection, and family regression had a negative effect on parenting behavior. Second, as for the effect of family-of-origin experience on self-esteem, it was found that family projection and emotional disconnection had a negative effect on self-esteem. Third, as for the effect of self-esteem on parenting behavior, it was found that judgment, behavior, and self-worth had a positive effect on parenting behavior. Lastly, it was found that self-esteem plays a partial mediating role in family-of-origin experience and parenting behavior. This study confirmed that parental self-esteem is a major parameter in the effect of parental family experience on parenting behavior, and is meaningful in providing basic data for parent education programs or counseling that can cope with future social crises.

Yoo, Jae Beom,Park, Sang-Wook,Kang, Ha Na,Mondkar, Hemant S.,Sohn, Kyunghwa,Kim, Hyun-Mi,Kim, Ki-Bum,Lee, Haiwon Elsevier 2014 Polymer Vol.55 No.16

<P><B>Abstract</B></P> <P>A new photoacid generator (PAG) bound polymer containing triphenylsulfonium salt methacrylate (TPSMA) was synthesized and characterized. The PAG bound polymer was employed to improve electron beam lithographic performance, including sensitivity and resolution. The PAG bound polymer resist exhibited a higher sensitivity (120 μC/cm<SUP>2</SUP>) than the PAG blend polymer resist (300 μC/cm<SUP>2</SUP>). Eliminating the post exposure baking process during development improved the resolution due to decreased acid diffusion. A high-resolution pattern fabricated by electron beam lithography had a line width of 15 nm and a high aspect ratio. The newly developed patterns functioned well as masks for transferring patterns on Si substrates by reactive ion etching.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Density Functional Study on the C-H Bond Cleavage of Aldimine by a Rhodium(I) Catalyst

심은지,Kyunghwa Yoo,전철호,최철호 대한화학회 2008 Bulletin of the Korean Chemical Society Vol.29 No.10

We investigated the C-H bond activation mechanism of aldimine by the [RhCl(PPH3)3] model catalyst using DFT B3LYP//SBKJC/6-31G*/6-31G on GAMESS. Due to their potential utility in organic synthesis, C-H bond activation is one of the most active research fields in organic and organometallic chemistry. C-H bond activation by a transition metal catalyst can be classified into two types of mechanisms: direct C-H bond cleavage by the metal catalyst or a multi-step mechanism via a tetrahedral transition state. There are three structural isomers of [RhCl(PH3)2] coordinated aldimine that differ in the position of chloride with respect to the molecular plane. By comparing activation energies of the overall reaction pathways that the three isomeric structures follow in each mechanism, we found that the C-H bond activation of aldimine by the [RhCl(PH3)3] catalyst occurs through the tetrahedral intermediate.

The Effect of Experience Economy of VR Contents on Satisfaction

Hwang, Kyunghwa,Yoo, Kunwoo Kyung Hee University Management Research Institute 2021 Asia pacific journal of business review Vol.5 No.2

The COVID-19 pandemic has ushered in a new era of untact and we are quickly adapting to this untact era. In the current situation where it is difficult to contact each other face-to-face, Virtual Reality (VR) is an opportunity factor for indirect tourism and a good alternative to viewing cultural heritage. This study showed that the effects of experience economies such as entertainment experience, aesthetic experience, escapist experience, and spiritual experience on VR content satisfaction. Furthermore, we examined whether consumers' perceived risks to COVID-19 moderate the relationship between experience economy and satisfaction. This study investigated 149 people who experienced VR content about Jerusalem. The results have shown that entertainment experience and aesthetic experience have a positive effect on the satisfaction with the VR content. Furthermore, perceived risks about COVID-19 have been shown to moderate the effects of aesthetic experience and spiritual experience on satisfaction. Finally, we provided implications based on our findings.

VR 기반 문화유산 체험이 방문의도에 미치는 영향

유건우(Kun Woo Yoo),황경화(Kyunghwa Hwang),권오병(Ohbyung Kwon) 한국전자거래학회 2021 한국전자거래학회지 Vol.26 No.2

최근 COVID-19 팬데믹으로 비대면 사회가 되면서 가상현실(VR) 기반으로 문화유산을 체험하려는 시도가 이어지고 있다. 그러나 VR 콘텐츠 체험이 실제 문화유산이 있는 관광지에 대한 방문으로까지 이어지는지, VR 콘텐츠 체험 만족으로 인해 관광지 방문 의도가 감소하지는 않는지에 대한 의문이 제기되고 있다. 이에 본 연구의 목적은 VR 기반 문화유산 체험이 유적지 방문 의도에 어떤 영향을 주는지를 실증적으로 파악하는 것이다. 또한, VR 기반 문화유산 체험이 Web 기반 문화유산 체험에 비하여 가지는 특징을 파악하고자 한다. 이를 위해 DeLone and McLean이 제안한 정보시스템 성공모델을 기반으로, 관광 콘텐츠 체험이 유적지 방문의도에 어떤 영향을 미치는지 살펴보았다. 더 나아가 콘텐츠 체험형태(VR vs. Web)에 따른 구조적 관계에 차이가 있는지 살펴보았다. 연구결과, VR 기반 콘텐츠 체험 시에 시스템 품질의 편리성과 정보 품질의 실재감, 유용성은 만족도에 정(+)의 영향을 미치는 것으로, 정보품질의 실재감과 만족도는 지속사용의도에 정(+)의 영향을 미치는 것으로 나타났다. 또한, 지속사용의도는 방문의도에 정(+)의 영향을 미치는 것으로 나타난 반면에 만족도는 방문의도에 통계적으로 유의한 영향을 미치지 않는 것으로 나타났다. 한편, Web을 통해 콘텐츠를 체험한 집단이 VR을 통해 콘텐츠를 체험한 집단보다 정보 품질의 유용성이 지속사용의도에 미치는 영향력의 크기가 더 큰 것으로 나타났다. 본 연구결과를 토대로 관광지에 대한 방문의도를 높이기 위한 VR 기반 관광 콘텐츠를 구성하는 방안에 대해 논의하였다. As it recently became a non-face-to-face society because of the COVID-19 Pandemics, attempts have been made to experience heritage based on virtual reality (VR). Despite the satisfaction of VR contents, however, questions are being raised about whether the VR experience leads to visit a heritage tour or reduces to visit a heritage tour. This study examined how VR-based heritage experiences affect the visit intention of heritage sites. In addition, this study investigated how VR-based experiences differently affect the visit intention compared to web-based experiences. To this end, based on the information success model proposed by DeLone and McLean, this study examined how the perception for system quality and information quality through VR (vs. web) experience affects the intention of visiting the historical site. The results demonstrated that satisfaction was positively influenced by the convenience of system quality and the presence and usefulness of information quality and that the presence and satisfaction positively affected continuance intention. In addition, continuous intention to use positively affected the visit intention of heritage sites. Lastly, it has been shown that the usefulness of information quality in groups experiencing content through the Web (vs. VR) has a greater impact on the intent of continuous use. Based on the results of this study, we discussed ways to organize tourism content to increase the intention of visiting heritage sites.

Evaluation of the Ostium in Anomalous Origin of the Right Coronary Artery with an Interarterial Course Using Dynamic Cardiac CT and Implications of Ostial Findings

Kim Jin Young,Hong Yoo Jin,Han Kyunghwa,Lee Suji,Kim Young Jin,Choi Byoung Wook,Lee Hye-Jeong 대한영상의학회 2022 Korean Journal of Radiology Vol.23 No.2

Objective: We aimed to evaluate the ostium of right coronary artery of anomalous origin from the left coronary sinus (AORL) with an interarterial course throughout the cardiac cycle on CT and analyze the clinical significance of the ostial findings. Materials and Methods: From January 2011 to December 2015, 68 patients (41 male, 57.3 ± 12.1 years) with AORL with an interarterial course and retrospective cardiac CT data were included. AORL was classified as high or low ostial location based on the pulmonary annulus in the diastolic and systolic phases on cardiac CT. In addition, the height, width, height/width ratio, area, and angle of the ostium were measured in both cardiac phases. After cardiac CT, patients were followed until December 31, 2020 for major adverse cardiac events (MACE). Clinical and CT characteristics associated with MACE were explored using Cox regression analysis. Results: During a median follow-up period of 2071 days (interquartile range, 1180.5–2747.3 days), 13 patients experienced MACE (19.1%, 13/68). Seven (10.3%, 7/68) had the ostial location change from high in the diastolic phase to low in the systolic phase. In the univariable analysis, younger age (hazard ratio [HR] = 0.918, p < 0.001), high ostial location (HR = 4.008, p = 0.036), larger height/width ratio (HR = 5.621, p = 0.049), and smaller ostial angle (HR = 0.846, p = 0.048) in the systolic phase were significant predictors of MACE. In multivariable cox regression analysis, younger age (adjusted HR = 0.917, p = 0.002) and high ostial location in the systolic phase (adjusted HR = 4.345, p = 0.026) were independent predictors of MACE. Conclusion: The ostial location of AORL with an interarterial course can change during the cardiac cycle, and high ostial location in the systolic phase was an independent predictor of MACE.

Chemotherapy-Related Cardiac Dysfunction: Quantitative Cardiac Magnetic Resonance Image Parameters and Their Prognostic Implications

Kim Jinhee,Hong Yoo Jin,Han Kyunghwa,Kim Jin Young,Lee Hye-Jeong,Hur Jin,Kim Young Jin,Choi Byoung Wook 대한영상의학회 2023 Korean Journal of Radiology Vol.24 No.9

Objective: To quantitatively analyze the cardiac magnetic resonance imaging (CMR) characteristics of chemotherapy-related cardiac dysfunction (CTRCD) and explore their prognostic value for major adverse cardiovascular events (MACE). Materials and Methods: A total of 145 patients (male:female = 76:69, mean age = 63.0 years) with cancer and heart failure who underwent CMR between January 2015 and January 2021 were included. CMR was performed using a 3T scanner (Siemens). Biventricular functions, native T1 T2, extracellular volume fraction (ECV) values, and late gadolinium enhancement (LGE) of the left ventricle (LV) were compared between those with and without CTRCD. These were compared between patients with mild-to-moderate CTRCD and those with severe CTRCD. Cox proportional hazard regression analysis was used to evaluate the association between the CMR parameters and MACE occurrence during follow-up in the CTRCD patients. Results: Among 145 patients, 61 had CTRCD and 84 did not have CTRCD. Native T1, ECV, and T2 were significantly higher in the CTRCD group (1336.9 ms, 32.5%, and 44.7 ms, respectively) than those in the non-CTRCD group (1303.4 ms, 30.5%, and 42.0 ms, respectively; P = 0.013, 0.010, and < 0.001, respectively). They were not significantly different between patients with mild-to-moderate and severe CTRCD. Indexed LV mass was significantly smaller in the CTRCD group (65.0 g/m2 vs. 78.9 g/m2; P < 0.001). According to the multivariable Cox regression analysis, T2 (hazard ratio [HR]: 1.14, 95% confidence interval [CI]: 1.01–1.27; P = 0.028) and quantified LGE (HR: 1.07, 95% CI: 1.01–1.13; P = 0.021) were independently associated with MACE in the CTRCD patients. Conclusion: Quantitative parameters from CMR have the potential to evaluate myocardial changes in CTRCD. Increased T2 with reduced LV mass was demonstrated in CTRCD patients even before the development of severe cardiac dysfunction. T2 and quantified LGE may be independent prognostic factors for MACE in patients with CTRCD.
