국내 제조기업의 온실가스 배출이 타인자본비용에 미치는 영향

서희영,홍종호 한국환경경제학회 2024 자원·환경경제연구 Vol.33 No.4

이 연구의 목적은 국내 제조기업의 온실가스 배출이 타인자본비용에 미치는 영향을 실증 분석하는 데 있다. 이를 통해 탈탄소화 시대에 기업의 온실가스 감축 투자가 금융비용 측면에서 잠재적 이익을 가져오는지 여부를 탐색하고자 한다. 국내 상장 제조기업의 2011년부터 2022년까지 온실가스 배출량과 재무정보를 통해 2,154개의 불균형패널자료를 구축한 후 고정효과모형을 이용하여 분석하였다. 분석 결과, 목표관리제 기간에 다배출 업종 중소기업의 탄소집약도와 타인자본비용 간 통계적으로 유의한 양의 상관관계가 발견되었다. 배출권거래제 도입 이후에는 탄소집약도와 타인자본비용 간 유의한 양의 상관관계가 다배출 대기업으로 확장되어 나타났다. 급격한 경기침체를 가져왔던 코로나19 팬데믹 기간에는 두 변수 간 유의한 관계가 발견되지 않았다. 업종별 분석 결과, 반도체‧디스플레이, 전기전자에서 동일 업종 내 다배출 기업의 탄소집약도 증가 시 타인자본비용이 증가하는 것으로 나타났다. 이러한 연구결과는 국내 제조기업의 온실가스 감축 투자가 비용만 유발하는 것이 아니라 타인자본비용 절감이라는 유의미한 편익을 가져올 수 있다는 실증적 증거를 제시한다. This study investigates whether Korean manufacturing firms can potentially lower financing costs through carbon abatement investments analyzing the effect of firms’ greenhouse gas (GHG) emissions on the cost of debt capital. We use data on GHG emissions and finances of listed Korean manufacturing firms from 2011 to 2022 and construct an unbalanced panel dataset comprising 2,154 observations. A fixed effects model is employed in the empirical analysis. The results show a statistically significant positive correlation between carbon intensity and the cost of debt capital for SMEs in the high-emitting industries under the Target Management System. After the introduction of the Emission Trading System in 2015, this positive correlation was expanded to high-emitting large companies. No significant correlation was found during the COVID-19 pandemic, which led to an abrupt economic downturn. Industry-specific findings further suggest that high-emitting companies in semiconductors/display and electronics sectors face increased cost of debt capital as carbon intensity rises. These empirical findings suggest that carbon abatement investment by Korean manufacturing firms can yield financial benefits in the form of lower cost of debt capital.

This study was performed to compare the foodservice management practices in the employee feeding operations of Jeonnam and Chungchong area. Questionnaires were developed and mailed to 160 dietitians with management in employee foodservice of Jeonnam and Chungchong area. Completed questionnaires were received from 124 dietitians with a response rate of 77.5%. The results of this study can be summarized as follows:. Age, work experience, concurrent position and work time of dietitians were significantly higher in the Chungchong area than those in the Jeonnam area. Times of meals and amount of meals served per day in the Chungchong area were significantly higher than those in the Jeonnam area. The type of menu by foodservice operation was high non-selective menu in both areas, especially non-selective menu was high in self-operated place whereas selective menu was high in contract management. Period of cycle menu was 10 - 15 days in Jeonnam area, but that was 7 days in Chungchong area and so cycle menu of both areas was significantly different (p < 0.001). Most considerable factor in menu planning was preference in Jeonnam area and was cost in the Chungchong area. Food purchasing method was used mostly by automatic computerized order in the Jeonnam area whereas telephone or mail order was high in the Chungchong area.

창의성 역설: 창의성이 중요하다고 믿을수록 타인의 창의적 특성을 더 바람직하게 평가하는가?

서희영,장재윤 한국산업및조직심리학회 2023 한국심리학회지 산업 및 조직 Vol.36 No.4

본 연구는 사회 전반에 걸쳐 창의성이 강조되나 창의적인 사람은 환영받지 못하는 현상을 조명하고 이에 영향을 미치는 개인차 변인을 탐색하고자 하였다. 미국 교사들의 창의적 성 격특성에 대한 역설적 지각을 재확인한 선행 연구(Kettler et al., 2018)를 따라 연구 1에서는 한국 초․중․고등 교사 172명을 대상으로 개인차 변인을 조사하고, 학생들의 성격특성(창의 적 및 반창의적 특성)을 평가하게 하였다. 그 결과 한국 교사들 역시 창의적 성격특성을 덜 바람직하게 평가하는 것으로 나타나 선행 연구의 결과를 재확인하였다. 이를 확장하여 연구 2에서는 한국 기업의 정규직 331명을 대상으로 창의성 역설 현상과 이에 대한 창의적 마인 드셋의 영향을 살펴보고자 하였다. 분석 결과, 창의성에 대한 역설이 직장 맥락에서 더욱 두 드러지게 나타났다. 선행 연구 및 연구 1에서와 같이 타인의 창의적 성격특성 평가에 유일 하게 영향을 미치는 개인차 변인은 자기 창의성 지각으로 나타났으며, 이를 창의적 성장 마 인드셋이 조절하는 것으로 나타났다. 마지막으로 본 연구가 갖는 시사점과 연구의 제한점 및 향후 연구 방향에 대해 논의하였다. This study aims to shed light on Creativity Paradox which is a phenomenon that creative people are not appreciated where creativity is emphasized, and to explore individual differences that affect the phenomenon. As per the previous research (Kettler et al., 2018) that even teachers who say they value creativity as educational goals actually find creative characteristics undesirable through the replication from school (Study 1) and expansion to organization (Study 2). In Study 1, 172 schoolteachers in Korea completed 2 waves of survey for the importance of educational goals including creativity and personal creativity with the desirability on characteristics for both creative indicative and contraindicative. In study 2, 331 fulltime employees completed 2 waves of survey including creative mindsets. Result indicated that both teachers and employees in this study rated characteristics associated with creativity as less desirable than those characteristics that are considered contraindicative, which confirms the Creativity Paradox. No effects were found based on the individual differences, but the level of personal creativity related to how desirable they rate others’ characteristics associated with creativity. As a result of hierarchical regression analysis, the moderating effect of creative growth mindset was partially presented in the relationship between the personal creativity and the members’ perception of creative characteristics, while no effect of fixed-creative mindset was presented. This study was intended to highlight the need of examining the implicit theory of, attitude toward, and changes of norms and climate related to creativity in the organizational context The implications, limits and future research suggestions were discussed.

영역 특수성에 따른 작업기억의 훈련 효과: 메타분석

서희영,김초복 한국인지및생물심리학회 2014 한국심리학회지 인지 및 생물 Vol.26 No.4

Working memory(WM) plays an important role in various cognitive tasks. Accordingly, WM training programs have been developed in order to enhance cognitive functions. However, it has been under debate on the effects of the training program. In this study, we performed meta-analyses to test whether WM training programs can improve other cognitive functions based on the domain-specificity of WM. In doing so, we classified previous studies as “congruent” or “incongruent” according to whether the domains of training programs were consistent with those of the measurement tools. As categorized general cognitive task involving measurement task about attention, inhibition, verbal ability and intelligence as well as WM task according to domain specificity, we examined improvement of general cognitive ability when the specific WM domain in the cognitive function was trained. Then, effect sizes were calculated based on statistics reported in the previous studies and meta-analyses were conducted in consideration of measurement periods and participants characteristics. Additionally, Chi square analyses were performed in order to confirm that the domain-specificity could be an important variable in the training effects. The results showed that domain congruency had a great influence on the training effects. The effect sizes were greater when training and measurement domains were consistent than when those were inconsistent, for both of the immediate and follow-up measurements. In addition, the effect of the congruency was greater in the patient groups compared to the normal groups. These findings suggest that the domain-specificity of WM training is an important factor in deciding the effects of the WM training programs. 작업기억은 다양한 인지 과제에서 핵심기능을 담당한다. 이로 인해 인지 기능 향상을 목적으로 작업기억 훈련 프로그램들이 개발되어 왔다. 그러나 그 훈련 효과에 대해서는 논란이 제기되고 있다. 이에 본 연구에서는 작업기억의 영역 특수성을 바탕으로 하여 메타분석을 수행하여 기존 훈련들의 효과성을 검증하고자 하였다. 이를 위해, 선행 연구들에서 사용된 훈련 프로그램에 포함된 작업기억 영역과 측정 도구들이 요구하는 영역의 일치 여부에 따라 연구들을 분류하였다. 이 때, 작업기억 과제뿐만 아니라 주의, 억제, 언어능력, 지능과 같은 일반 인지 능력을 측정하는 과제도 작업기억 영역 특수성에 따라 분류하여, 일반 인지 능력이 포함하고 있는 작업기억을 구체적으로 훈련시키는 것이 인지 능력 향상에 어떠한 영향을 미치는가를 살펴보았다. 이 후, 각 연구들이 보고한 통계치를 바탕으로 효과크기를 구하고, 측정 시기와 참가자 특성을 고려하여 메타 분석을 실시하였다. 추가적으로 교차분석을 수행하여, 영역 일치 여부가 훈련 효과에 큰 영향을 미칠 변인이 될 수 있음을 확인하고자 하였다. 연구 결과, 작업기억의 영역들의 일치 여부가 훈련 효과에 중요한 영향을 미치는 것으로 나타났다. 훈련한 영역과 측정한 영역들이 일치하지 않는 경우보다 일치할 때 더 큰 효과크기를 보였으며 이는 지연 측정을 수행했던 연구들에서도 나타났다. 또한 영역 일치에 따른 효과성의 차이는 환자 군에서 더 큰 것으로 나타났다. 본 연구의 결과는 작업기억의 영역 특수성이 훈련 효과에 영향을 미치는 요인임을 시사한다.

Neural Evidence for Cognitive Style-Specific Strategies in Cognitive Control

서희영,김초복 한국인지및생물심리학회 2017 한국심리학회지 인지 및 생물 Vol.29 No.3

Cognitive control involves the human ability to attend to relevant information and ignore irrelevant information from environmental inputs. The present study examined neural mechanisms involved in cognitive control for relevant or irrelevant information related to individual cognitive style. Based on the Object-Spatial-Verbal cognitive style questionnaire scores, participants were divided into two preference groups, Spatializers and Verbalizers. The task included two versions of spatial Stroop tasks that required both ignoring spatial distracter while attending to a verbal target (the Word task) or an object target, respectively. Although there was no difference in the behavioral Stroop effects in either task between the two groups, imaging results demonstrated an increase in the neural Stroop effect in the right frontopolar cortex and right superior temporal sulcus for Spatializers compared to Verbalizers during the Word task, with greater activation in the left lingual gyrus and left parahippocampal/fusiform gyrus for Verbalizers compared to Spatializers during the Object task. In addition, functional connectivity between the dorsolateral prefrontal cortex and task-related regions showed group differences in the neural Stroop effect. The current results provide further evidence that individuals appear to use different strategies for cognitive control processes according to their preferential cognitive style.

Objectives The aim of this study was to develop a carbohydrate-preference rating scale (CPRS) and to investigate its validity and reliability. Methods A 10-item questionnaire was developed or selected by three psychiatrists. The questionnaire was administered to 157 female college students in Seoul. Construct validity was investigated by performing a principal component analysis, and reliability was assessed in terms of internal consistency using Cronbach’s alpha. Results The principal component analysis revealed three factors underlying carbohydrate prefer-ences : habits of carbohydrate consumption, ability to control the consumption of carbohydrates and body weight, and the addition of sugar when drinking coffee. Taken together, these three factors accounted for 57.390% of the common variance. Cronbach’s α was high, indicating the reliability of the questionnaire was satisfactory. When comparing the total score of the questionnaire by T test, the eating disorder group showed higher score than the control group. Conclusion The results indicate that the CPRS is a reliable and valid scale for assessing carbo-hydrate preferences. Although there are a lot of limitations, present study has significance as the basis of future research.

The purposes of this study were to develop a program of dance integration education that had the overall characteristics of dance reflected and integrated dance into other subjects specifically, to provide objective and empirical data by reviewing its correlations with self-efficacy, and to search for the potential of developing and applying the program in the field. It also aimed to make a contribution to the activation of elementary dance education. The subjects of the study were 40 students from two third-grade classes in K Elementary School located in Seoul. They were divided into the experimental and control group, which each consisted of 20. The program of dance integration education was administered to the experimental group for total ten sessions, each of which lasted for 40 to 50 minutes. The group that participated in the program of dance integration education was chosen as the experimental group to test the effects of the treatment. A pretest was given before the treatment, and a posttest was given after the treatment. Using two-way ANOVA according to the 2(group)x2(test) factorial design with repeated measures on test, the difference between the groups was tested. Based on the research findings and previous study, the following conclusions were drawn: The pre- and post-test results of the experimental group indicated that there was statistically significant difference of 0.1% level in the intellectual area, social and emotional area, and physical area of the subareas of self-efficacy. Those results support the hypothesis that the program of dance integration education would have positive impacts on the intellectual, social and emotional and physical subarea of children`s self-efficacy. They also make the study as an empirical one that investigated the relationships between a program of dance integration education and children`s self-efficacy. Those conclusions have important implications that they can stimulate ongoing concern with the activities of arts education in school as well as interest in and changes to the fundamental arts subjects. They also imply that a program of dance integration education can be integrated into the lecture process in school and used in a wide range.
