정나래,김은정 한국인지행동치료학회 2019 인지행동치료 Vol.19 No.1

Depression is mental disorder that is characterized by decreased positivity. This study investigated whether responses to positive affect influence depression, and interact with positive life events. College students(n=448) were taken to self report assessment for responses to positive affect, emotion clarity, negative rumination, positive and negative life events, depression. As a result, dampening significantly influenced depression, but there were no interaction effects with positive life event. Positive rumination influenced depression, moreover there were three-way interaction effects including emotional clarity and positive life events as moderator variable. And negative rumination significantly influences depression, but there were no interaction effects with negative life events. This results suggest that the responses to positive affect influences depression, and partially interacts with positive life events as stressor. Finally, implications, limitations of the study, and future research options were discussed. 우울증은 긍정성의 감소를 특정적인 요인으로 갖는 대표적인 정신장애이다. 본 연구는 대학생들을 대상으로 우울증의 정서 조절 기제인 긍정 정서 반응이 우울을 설명하는지를, 그리고 긍정 정서 반응과 생활 사건이 상호작용하여 우울을 설명하는지를 검증하였다. 대학생 448명을 대상으로 긍정 정서 반응, 정서 인식 명확성, 부정 반추, 생활사건, 우울을 자기 보고식 질문지로 측정하였다. 연구 결과, 우선 긍정 정서에 대한 반응의 하위 요인 중 가라앉히기(dampening)는 우울 증상에 유의미한 수준으로 정적인 영향을 끼치는 것으로 나타났으나 긍정 생활 사건과의 조절 효과는 나타나지 않았다. 또한 긍정 반추는 유의미하게 우울 증상에 부적인 영향을 끼치는 것으로 나타났으나, 정서 인식 명확성과의 조절 효과는 나타나지 않았다. 다만, 긍정 반추와 우울 증상과의 관계에서 정서 인식 명확성과 긍정 생활 사건의 조절 효과가 나타났다. 긍정적인 생활 경험이 적을 때, 긍정 반추가 높은 사람들은 긍정 반추가 낮은 사람들에 비해 정서 인식 명확성이 높을수록 우울 증상을 훨씬 덜 경험하는 것으로 나타났다. 반면, 긍정 생활 사건이 많을 때, 긍정 반추와 정서 인식 명확성의 정도에 따른 우울의 변화가 유의미하게 나타나지 않았다. 또한 부정 반추는 우울 증상에 유의미한 수준으로 정적인 영향을 끼쳤으며, 부정 생활 사건과의 조절 효과는 나타나지 않았다. 본 연구 결과는 긍정 정서에 대한 반응 즉, 가라앉히기 및 긍정 반추가 대학생의 우울 증상에 각각 정적 및 부적 영향을 끼치며, 생활 사건이라는 스트레스 요인이 이들과의 관계에서 부분적으로 상호작용을 할 수 있다는 것을 시사한다. 마지막으로 연구의 의의와 제한점을 논의하였다.

정나래,김은정 한국청소년학회 2021 청소년학연구 Vol.28 No.1

The purpose of this study was to examine the effects of group ACT and group Positive ACT for depressed college students. Positive acceptance and commitment therapy was developed by the researchers by integrating some elements of positive psychological treatment in addition to the Acceptance and commitment therapy for depression protocol. The participants used in the final analysis were 18 people assigned to ACT, 17 people assigned to Positive ACT, and 19 people in Control, all of whom performed pre- and post-assessment of depression symptoms, acceptance, psychological rigidity, defusion, value, happiness, positive emotion, negative emotion, dampening, positive rumination, and life satisfaction, respectively, before and after treatment. Comparison between groups showed no change over time in control group, while the two treatment groups showed a decrease in depression and psychological rigidity, and increased acceptance, happiness, and life satisfaction after treatment compared to before treatment. Both treatment group showed improvement in happiness and positive emotions after treatment compared to the control group, but unexpectedly there was no significant difference between the two treatment groups. Both ACT and Positive ACT have been suggested to be effective for overall mental health, in depressed college students. Finally, the implication and limitations of the study and the direction of future research were discussed. 본 연구는 우울 증상이 있는 대학생을 위해 집단 수용전념치료 및 긍정수용전념치료를 개발한 후 실시하여, 두 가지 집단 심리치료의 효과를 검증하였다. 우선 우울증을 위한 기존의 수용전념치료 프로토콜을 활용하여 수용전념치료를 시행하였고, 긍정수용전념치료는 수용전념치료에 덧붙여 긍정심리치료의 일부 요소를 가미하여 연구자들이 개발하여 시행하였다. 최종 분석에 사용된 참여자들은 수용전념치료 집단 18명, 긍정수용전념치료 집단 17명, 통제 집단 19명으로 모두 54명이었다. 이들은 각각 우울 증상, 수용, 심리적 경직성, 탈융합, 가치로운 삶, 행복, 긍정 정서, 부정 정서, 가라앉히기, 긍정 반추, 삶의 만족에 대한 사전 및 사후 평가를 시행하였다. 연구 결과, 통제 집단에서는 변화가 나타나지 않았던 반면, 두 치료 집단에서 모두 치료 전에 비해 치료 후에 우울 증상과 심리적 경직성의 감소를 보였으며, 수용, 탈융합, 삶의 만족의 증가를 보였다. 한편, 긍정성과 관련한 측정치의 경우 수용전념치료와 긍정수용전념치료 집단은 통제 집단에 비해 치료 전보다 치료 후에 행복 및 긍정 정서에서의 향상을 나타내었으나, 가설과는 달리 두 치료 집단 간에는 유의미한 차이가 나타나지 않았다. 수용전념치료와 긍정수용전념치료는 모두 우울한 대학생의 우울 증상을 비롯하여, 전반적인 정신건강에 효과적인 것으로 시사되었다. 마지막으로 연구의 의의 및 제한점과 미래 연구의 방향성에 대해 논의하였다.

Genetic analysis of the tomato inquieta mutant links the ARP2/3 complex to trichome development

정나래,김희진,황인택,Gregg A. Howe,강진호 한국식물학회 2017 Journal of Plant Biology Vol.60 No.6

Trichomes are hair-like structures on the aerialsurface of many plant species. Trichomes are well characterizedfor their role as physical barriers and chemical defenseagainst herbivore attack. Here, we describe the characterizationof a monogenic recessive mutant of tomato (Solanumlycopersicum) called inquieta (ini). All trichome types on iniplants showed distinct morphological defects (e.g., swelling)that are known to be associated with defects in the actincytoskeleton. Genetic mapping experiments positioned theIni locus within a 1.5 cM interval on chromosome 11 thatcontains the tomato homolog of the Arabidopsis ARPC2Agene, which encodes a protein involved in nucleating thepolymerization of actin filaments. Use of ARPC2A as amolecular marker showed that this gene strictly co-segregateswith the target locus in a mapping population of 135 F2plants. Reverse transcriptase (RT)-PCR and genomic PCRexperiments showed that full-length ARPC2A is amplified inwild-type but not in the ini mutant. Flanking PCR andSouthern blot analysis showed that the ini mutation correspondsto a complex ~6-kb insertion in the 5th intron of ARPC2A. These results provide molecular evidence that alteredtrichome development in the ini mutant is caused by a defectin actin cytoskeleton formation.

Intra-Articular Injection of High-Dose ELHLD Peptide for Managing Canine Stifle Osteoarthritis: Kinetic Gait Analysis

정나래,강병재 한국임상수의학회 2021 한국임상수의학회지 Vol.38 No.3

Intra-articular injection of ELHLD peptide is considered to have a therapeutic effect in osteoarthritis (OA) through the inhibition of transforming growth factor–β1. This study aimed to assess the efficacy of intra-articular injections of high-dose ELHLD peptide (100 μg/kg) in canine stifle OA. Six client-owned dogs diagnosed with stifle OA were included. Selected dogs were treated with an intra- articular injection of high-dose ELHLD peptide (100 μg/kg). Outcome measures, including orthopedic examination, gait analysis, and Canine Brief Pain Inventory (CBPI) score, were evaluated four times after injection. Orthopedic examination, gait analysis, and owner’s assessment (CBPI) improved significantly from 4 weeks after injection. In conclusion, we obtained sufficient evidence from this small sample that high-dose ELHLD peptide improves clinical signs of canine OA not only through subjective assessment but also through objective evaluation.

수용 전념 치료(ACT)가 알코올 의존 환자들의 정신건강에 미치는 효과

정나래,이민규 한국건강심리학회 2014 한국심리학회지 건강 Vol.19 No.4

본 연구는 알코올 의존 환자들을 대상으로, 수용 전념 치료(ACT)의 효과를 알아보았다. 원치 않는 사적 사건을 경험하지 않으려는 경향성인 ‘경험 회피’가 알코올 사용 및 관련 병리에 결정적인 영향을 준다는 이론에 초점을 맞추어, 수용과 인지적 탈융합, 맥락으로서의 자기, 현재에 존재하기, 가치, 전념적 행동의 요소를 가지며 심리적 유연성을 기를 수 있게 하는 수용 전념 치료(ACT)를 알코올 의존환자들에게 적용하여, 수용과 전념의 증가뿐만 아니라 정서에서의 변화, 자존감, 삶의 만족도에의 영향, 알코올 사용에서의 변화 역시 기대하였다. 병원에서 입원 치료를 받고 있는 알코올 의존 환자들 중 수용 전념 치료(ACT)집단에 12명, 통제 집단에 12명 할당하였다. 수용 전념 치료(ACT)프로그램은 8회기로, 각 회기는 90분으로 진행되었다. 수용 전념 치료(ACT) 집단과 통제 집단의 사전 및 사후 평가 점수의 평균을 비교하는 반복 측정 변량 분석을 실시하였다. 그 결과 수용 전념 치료(ACT) 프로그램 집단에서 정서적 수용, 긍정적 정서, 자존감, 삶의 만족, 음주 변화 결과 기대에서의 변화가 나타났다. 본 연구를 통해 알코올 의존 환자들의 정신 건강에 수용 전념 치료(ACT)가 긍정적인 영향을 준다는 것을 확인하였다. 마지막으로 본 연구의 함의점과 제한점, 후속 연구를 위한 제안이 논의되었다. The purpose of this study is to investigate the effects of Acceptance-Commitment Therapy (ACT) on mental health of inpatients with alcohol dependence. The study was designed so that the therapy focused on the theory that alcohol use and its pathology are primarily caused by experiential avoidance, which is the tendency not to experience unwanted private events. ACT has core components including acceptance, cognitive defusion, self as context, being present, values, and committed action. We expected the effects on mental health factors to not only increase acceptance-commitment but also to change psychological well-being and pattern of alcohol use. Twelve inpatients with alcohol dependence were in the ACT group and 12 participants were in the control group. The ACT program comprised eight 90-minute sessions. Repeated measure of ANOVA was used to compare pre-test mean to post-test mean. Positive changes appeared in emotional acceptance, positive emotion, self-esteem, life satisfaction, and drinking outcome expectancy. These results confirm ACT as and effective psychotherapy for mental health of inpatients with alcohol dependence. The implications and limitations of this study are discussed with suggestions for future study.
