  • This work describes a preliminary investigation to a learning model based on cybernetics and radical constructivism. To achieve this purpose, main ideas of cybernetics, i.e., negative feedback, difference, self-regulation, equilibrium, and purpose-directed behavior was analysed under radical constructivism. Powers' model, which consists of hierarchically arranged negative feedback systems, is introduced into this work. This was based on the claim that living organisms behave to control perceptions. By adding the notion of scheme from the view of radical constructivism, a learning procedure, which consists of six steps, was suggested in this work.

  • 사회 변화의 가장 중요한 원인 중의 하나는 세대 간 차이이다. 어떠한 대상에 대해 연령대별로 어떠한 인식을 지니고 있는가를 살펴보는 것은 그 대상이 현재 어떤 상태이고, 또 앞으로 어떤 방향으로 나아갈지에 대한 시금석이 될 수 있다. 따라서 본 연구에서는 연령대별로 규제 인식에 대한 차이가 존재하는지를 살펴보고자 한다. 연령대별 규제인식 차이 여부를 검증하는 것은 우리 사회의 규제 현상을 이해하는데 도움을 줄 수 있다. 분석결과 규제에 대한 인식은 연령에 따라 차이가 존재하고 있다. 연령대가 높을수록 규제에 대해 긍정적인 성향을 보이고, 연령대가 낮을수록 규제에 대해서 부정적인 인식을 지니고 있다. 특히 규제의 전문성 부문과 대기업에 대한 규제 등에 대해서는 50대와 20대가 서로 반대로 인식하고 있었다. 규제에 대해서 연령차이가 존재한다는 것은 규제 정책 제정 및 집행과 관련해서 보다 다양한 측면을 고려할 필요가 있다는 점을 제시한다.

  • The purpose of this study was to identify the effect of experience emotion (i.e., happy, proud, sad, fear) on the risk perception. This study also examined interaction effects of emotion regulation (i.e., reappraisal strategy, problem focused strategy) between experience emotion and risk perception. The study collected data from 168 flight crew members in Korean commercial airlines, using an online research in which an experiment of emotion manipulation and a survey were included. The results of the study found the positive effect of happiness emotion on the risk perception regarding cases 1(these cases have high possibility of negative result and low circumstance control) and the positive effect of sadness emotion on the risk perception regarding cases 2(these cases have low possibility of negative result and high circumstance control). This study also found the interaction effect of reappraisal emotion regulation strategy between the relationship of happiness and risk perception regarding cases 2. From these results, the study provided that theoretical and practical implication that happiness and sadness emotion contribute risk perception and reappraisal strategy has a moderating role in the relationship between happy emotion and risk perception. Finally, based on these results, the limitations of this study and future research were discussed.

  • Both glycerol-phosphate acyltransferase (GPAT) and 7.2 kb mRNAs were present at the highest level in liver. Glycerol-phosphate acyltransferase and 7.2 kb mRNA levels increased dramatically when fasted mice were refed a high carbohydrate diet. In mature 3T3-L1 adipocytes, insulin increased both glycerol-phosphate acyltransferase and 7.2kb mRNA levels 2.6 to 3-fold while dibutyryl cAMP decreased mRNA levels by 50% and 80%, respectively. These results indicate positive regulation by insulin and negative regulation by dibutyryl cAMP of both glycerol-phosphate acyltransferase and 7.2 kb mRNA.

  • Purpose: The purpose of this study was to explore influencing factors of dysfunctional beliefs and emotion regulation strategy for nurses' problem solving ability. Methods: This study was a cross-sectional design with a sample of 745 nurses from 1 university hospital located in Gyeonggido. The scales were Dysfunctional Beliefs Test (70 items), Emotion Regulation Strategy Questionnaire (25 items) and Social Problem Solving Inventory (52 items). The data were analyzed using SPSS 17.0 employing ANOVA, pearson correlation coefficients and multiple regression analysis. Results: The mean score for problem solving ability was 11.26 points. Influencing factors for nurses' problem solving ability were identified as 'active regulation style' in emotion regulation strategy and 'negative concept of social self' in dysfunctional beliefs. Conclusion: It is plausible to assume that dysfunctional beliefs which are vulnerability factors in cognitive variables and emotion regulation strategy affect nurses' problem solving ability.

  • Emotion regulation has been suggested as a pathway through which personality traits (e.g., extraversion or neuroticism) affect psychological well-being. However, the pathway needs further investigation across cultures due to variations in parts of the relationship reported in recent culture research. With an aim of improving current understanding of the pathway, we investigated the role of emotion regulation mediating the link between personality traits and well-being across two college samples from different cultural backgrounds: Korea and the United States (US). Results of mediation analysis revealed that the extraversion-well-being relationship was fully mediated by the degree to which individuals regulate negative emotions in both Korean and US samples. However, the neuroticism-well-being relationship was partially mediated by emotion regulation in the US sample, while it was fully mediated in the Korean sample. The role of emotion regulation differently functioning across cultures suggests the importance of investigating cultural-specific mechanism of psychological processes.

  • This research examined the relation between emotional expression of parents and self-regulation in children. The subjects were 116 3rd and 6th grade Sunday school children and their parents in 13 churches in Seoul and Kyunggi Province. Data were analyzed by the sex, age and self-regulation of the children and emotional expressiveness of the parents using two-way ANOVA and multiple regression analysis. Results were that mothers showed higher levels of emotional expression than fathers. Positive emotional expression of fathers was related to the self-regulation of sons but not daughters. Positive emotional expression of mothers was related to the self-regulation of daughters but not sons.

  • 자동차는 우리에게 생활의 편리함을 준 반면 대기오염이나 교통사고와 같은 심각한 문제들도 안겨주었다. 이에 교통사고를 줄이기 위한 여러 가지 정책들이 실시되고 있지만 보다 근본적인 교통사고 예방대책을 찾기 위해서는 더욱 다양한 연구가 필요하다. 우리나라 국민 정신건강 조사통계에 따르면 대표적인 부정적 정서로 꼽을 수 있는 우울과 불안이 점차 증가하고 있는 추세이지만 이와 관련하여 운전행동과의 연구는 거의 없는 실정이다. 이에 본 연구에서는 구조방정식을 이용하여 우울과 불안을 포함한 운전자의 부정적 정서요인과 운전행동과의 구조모형을 구축하였다. 여기에 인간의 정서는 최종 행동으로 모두 나타나지 않으며 정서조절의 단계를 거친다는 연구를 토대로 정서조절 방략을 반영하여 이를 분석하는 것이 본 연구의 목적이다. 분석결과 운전자의 부정적 정서는 안전운전보다는 위험운전행동에 더 많은 영향을 주며 정서조절 방략 중에서는 감정표현 억제가 더 많은 영향을 주는 것으로 나타났다. 또한 인지적 재해석은 안전운전을 추구하는 순행적 대처행동에, 감정표현 억제는 위험운전을 감행하는 역행적 대처행동에 (+) 영향을 미치며 부정적 정서요인들을 매개로 한 총효과 분석에서는 감정표현 억제가 인지적 재해석보다 미치는 영향이 컸다. 본 연구는 운전자의 운전행동에 대한 이해를 증진시키고 교통사고를 줄이기 위한 정책의 기초 연구로서 의미가 있다고 할 수 있다.

  • Ralstonia solanacearum causes bacterial wilt in a wide variety of host plant species and produces a melanin-like blackish-brown pigment in stationary phase when grown in minimal medium supplemented with tyrosine. To study melanin production regulation in R. solanacearum, five mutants exhibiting overproduction of melanin-like pigments were selected from a transposon (Tn) insertion mutant library of R. solanacearum SL341. Most of the mutants, except one (SL341T), were not complemented by the original gene or overproduced melanins. SL341T showed Tn insertion in a gene containing a conserved domain of eukaryotic transcription factor. The gene was annotated as a hypothetical protein, given its weak similarity to any known proteins. Upon complementation with its original gene, the mutant strains reverted to their wild-type phenotype. SL341T produced 3-folds more melanin at 72 h post-incubation compared with wild-type SL341 when grown in minimal medium supplemented with tyrosine. The chemical analysis of SL341T cultural filtrate revealed the accumulation of a higher amount of homogentisate, a major precursor of pyomelanin, and a lower amount of dihydroxyphenylalanine, an intermediate of eumelanin, compared with SL341. The expression study showed a relatively higher expression of hppD (encoding hydroxyphenylpyruvate dioxygenase) and lower expression of hmgA (encoding homogentisate dioxygenase) and nagL (encoding maleylacetoacetate isomerase) in SL341T than in SL341. SL341 showed a significantly higher expression of tyrosinase gene compared with SL341T at 48 h post-incubation. These results indicated that R. solanacearum produced both pyomelanin and eumelanin, and the novel hypothetical protein is involved in the negative regulation of melanin production.

  • 우리나라는 수도권 과밀화해소를 위해 기업들의 수도권 입지에 대해 규제하고 있으나 그 기준이 행정구역상 위치에 의존하고 있다. 따라서 본 연구는 입지규제 차이가 기업의 경영성과나 혁신성에 어떠한 영향을 미치는지 인접해있는 평택(수도권)과 천안(비수도권)의 KIS-Value 기업자료를 이용하여 다중회귀분석과 음이항회귀분석을 수행하였다. 분석결과 경영성과측면에서는 두 지역기업 간에 차이를 발견할 수 없었으나 혁신성에서는 천안에 위치한 기업이 더 나은 성과를 보이는 것으로 나타났다. 이러한 분석결과는 입지규제가 기업의 혁신성에 부정적 영향을 미칠 가능성이 높으며 기업입지규제가 보다 정밀한 방식으로 개선될 필요가 있는 것으로 판단할 수 있다.
