The Strength of Weak Ties Revisited: 청소년의 사회연결망이 진로성숙에 미치는 영향

이가영,김신영 한국직업능력개발원 2009 직업능력개발연구 Vol.12 No.2

Not only did this study explore the effects, on the career maturity of teenagers, of individual factors of them(sex, department, region, educational background of parents, average monthly income of household), home environment factors(attachment to parents, family relations), school environment factors(attachment to teachers, attachment to friends), career-related activities and education factors, and psychological factors(emotion regulation), but also it found out whether social network has positive effects on the career maturity, and especially the hypothesis that the weak tie constituting the social network affects the career maturity much more than the strong tie does was precisely examined. As a result of the examination, social network affected significantly the career maturity even under the condition that all the independent variables were controlled, and the maturity was found to be high especially in case the weak tie became stronger. The results above supported the hypothesis of this study that the weak tie has more effects on the career maturity of teenagers than the strong tie does. 이 연구는 청소년의 진로성숙에 영향을 미치는 사회·인구학적 요인(성, 계열, 지역, 부모학력, 가구월평균소득), 가정환경 요인(부모애착, 가족관계), 학교환경 요인(선생님애착, 학교친구애착), 진로관련 활동 및 교육 요인, 심리적 요인(정서조절) 이외에 사회 연결망이 진로성숙에 긍정적으로 작용할 수 있을 것인지를 탐색하였다. 특히 사회 연결망 구성 중에서 약한 연결망이 강한 연결망 보다 청소년의 진로성숙에 미치는 영향력이 클 것이라는 가설을 검증하였다. 분석은 한국청소년정책연구원의 청소년패널 4차년도 자료 중 고등학교 2학년 3,449명을 대상으로 하였다. 다중회귀분석 방법에 의해 사회·인구학적 요인(성, 계열, 지역, 부모학력, 가구월평균소득), 가정환경 요인(부모애착, 가족관계), 학교환경 요인(선생님애착, 학교친구애착), 진로관련 활동 및 교육 요인, 심리적 요인(정서조절)을 단계적으로 투입, 통제하여 사회 연결망의 효과와 독립변수들 간의 상호작용 효과를 살펴보았다. 분석 결과, 사회 연결망은 다른 독립변수들을 모두 통제한 상태에서도 진로성숙에 유의미한 영향력이 있는 것으로 나타났으며 특히 약한 연결망이 강할수록 진로성숙이 높게 나타나 강한 연결망보다 약한 연결망이 청소년의 진로성숙에 영향력이 클 것이라는 본 연구의 가설을 지지하였다.

우울증을 위한 행동활성화 치료의 적용가능성 : 사례연구

이가영,차윤지,서호준,최기홍 한국인지행동치료학회 2016 인지행동치료 Vol.16 No.3

본 연구는 우울증 감소를 위한 행동활성화 치료가 국내에 적용가능하며 치료효과가 있는지 예비적으로 알아보고자 하였다. 이를 위해 행동활성화(Behavioral Activation) 치료의 원리와 과정에 대해 설명하였으며, 치료를 실시하여 각 사례의 결과를 척도별로 제시하였다. 행동활성화는 우울증 환자의 삶에서 적응적 활동의 빈도를 증가시키고 보상 획득에 방해가 되는 활동을 감소시키는 것을 목표로 한다. 행동활성화는 다수의 대규모 효과성 검증 연구 및 메타분석연구를 통해 우울장애에 대한 단독 치료로서 인정받았으며, 미국심리학회에 의해 우울증의 근거기반치료 중 하나로 채택되었다. 그러나 국내에서는 우울증 환자에게 행동활성화를 적용한 사례가 아직까지 보고되지 않았다. 따라서 행동활성화 치료의 보급을 위해 국내 우울증 환자에게도 적용이 가능한지 그리고 해외의 연구결과와 유사한 효과를 나타내는지 알아보고자 하였다. 본 연구에서는 지역사회 정신건강증진센터에서 의뢰된 우울증 환자 6명 중 연구 포함 및 제외기준을 만족하는 5명을 대상으로 행동활성화 치료 프로그램을 실시하였으며, 치료 사전 및 사후에 2개의 우울증상 평가 척도, 1개의 행동활성화 척도, 2개의 기능 평가 척도를 실시하고 그 결과를 분석하였다. 5명 가운데 4명이 10회기의 그룹치료를 완수하였으며, 그 중 2명이 행동활성화 치료에 반응하였다. 효과 크기는 중간에서 큰 수준 정도로 나타났으며, 이는 국내 지역사회 장면에서 행동활성화 치료를 적용하는 것이 가능함을 시사한다. 앞으로 대규모 무선통제연구를 통해 본 연구의 결과를 재검증하고 타당화 할 필요성이 요구된다. The purpose of this study was to provide the rationale and procedures of Behavioral Activation (BA) treatment for depression and to examine feasibility in patients with depression in Korea. The basic principle of the BA is to increase the frequency of adaptive behavior and to decrease engagement in activities that limit access to reward by integrating activity monitoring and activity scheduling into its main therapeutic components. Despite a number of large-scaled effectiveness trials and meta-analysis studies supporting the BA as an independent and efficacious treatment for depressive disorders, none has been reported in this country. To evaluate feasibility of the BA in Korean adults with depressive symptoms, the current study recruited participants from a community mental health center and delivered the 10-session group format BA to five individuals who met the study inclusion and exclusion criteria. At pre- and post-treatment, depressive symptoms, level of functioning, and behavioral activation level were assessed. With minimum drop-out rates (1 out of 5), 50% of the completers showed a large effect size for depressive symptoms, a medium to large for level of functioning, and a medium effect size for behavioral activation level. The current case study supports feasibility and thus future work should replicate the current findings with a larger sample in a controlled manner.

마음챙김 지시가 사회불안 성향이 있는 대학생들의 불안과 사후반추에 미치는 영향

이가영,김은정 한국임상심리학회 2016 Korean Journal of Clinical Psychology Vol.35 No.1

This study examined the effect of mindfulness on anxiety and post event-processing, as compared to distraction in socially anxious undergraduate students. Undergraduate students received the first speech task to induce anxiety, and were randomly assigned to three different treatment conditions; mindfulness condition(n=18), distraction condition(n=18), and control condition(n=18). They completed measures of subjective anxiety response before and after speeches. After receiving brief training, they underwent the second speech task and post-event rumination was assessed over the 24 hours period. Results indicated that the mindfulness group showed a greater decrease in subjective anxiety response before the speech than the other two groups, but there was no difference in subjective anxiety response after the speech between the mindfulness group and the distraction group. Next day, the mindfulness group reported less post-event rumination compared to the other two conditions. These results suggest that mindfulness can be an effective way to reduce anticipatory anxiety and post-event rumination in socially anxious individuals.

Randomized controlled trial (RCT) is one of the gold standards of evidence for efficacy of psychotherapy that allows causal interpretations between a specific psychotherapeutic approach and outcomes. Thus, results from the RCTs are considered a basis for determining which psychotherapeutic approaches should be delivered to the public. In the current study, we aimed to systematically review psychotherapy RCTs conducted in South Korea and to analyze them according to the journals published in and their publication periods (i.e., 1983-2003, 2004-2006, 2007-2011, and 2012-2015). In addition, we have evaluated the quality of RCTs by employing the Randomized Controlled Trial of Psychotherapy Quality Rating Scale (RCT-PQRS). A total of 91 RCTs were finally selected for the current analysis. Four journals (i.e., Korean Journal of Counseling and Psychotherapy, Korean Journal of Clinical Psychology, Korean Journal of Health Psychology, and Korean Journal of East West Mind Science) were included in the analysis since they published at least five RCTs. The results showed that there were no differences in study characteristics (e.g., sample characteristics, types of psychotherapy) between the research periods whereas RCT quality scores have increased over time. Overall, RCTs published in Korean Psychological Association (KPA) Journals had greater RCT quality scores than those published in non-KPA Journals. In terms of the analysis of published journals, there were significant differences in study characteristics (e.g., sample characteristics, types of control groups, types of psychotherapy) between journals. Several issues and implications are discussed for researchers and policy makers in order to enhance quality of RCTs and to disseminate evidence-based information about efficient psychotherapeutic approaches to the public.

우울증의 행동활성화 치료: 체계적 개관

이가영,차윤지,최기홍 한국임상심리학회 2016 Korean Journal of Clinical Psychology Vol.35 No.4

This study systematically reviewed previous theories that are fundamental to behavioral activation and support evidences accumulated over the past 25 years, in order to introduce behavioral activation for depression into the domestic clinical field. Recently, behavioral activation has been recognized as a stand-alone psychotherapy for depression with results supporting comparable effects as antidepressant medications or traditional cognitive therapy. In this comprehensive literature review on behavioral activation, we aimed to introduce the latest definition with a brief history, underlying theories, and core therapeutic components, and to provide information on studies evaluating efficacy, effectiveness, and cost-effectiveness. Moreover, we have also summarized the most recent efforts and studies evaluating its effects that have been made to extensively deliver the behavioral activation in various form (e.g., internet based) and to patient groups with diverse comorbidity disorders. Future directions and implications for clinicians and researchers were also discussed to encourage behavioral activation research, including dissemination to the local community.

이가영,김초윤,김주현,송인준,이윤정,박범진,송초롱 한국산림휴양복지학회 2023 한국산림휴양학회지 Vol.27 No.3

본 연구는 연령, 피로도 등 개인의 특성에 따른 숲길걷기운동처방 알고리즘을 도출하고, 특성별 선호 코스 유형 및 코스 선택 요인을 분석하여 안전하고 효율적인 건강관리 활동으로써의 숲길걷기운동을 위한 기초자료를 마련하는 것을 목적으로 하였다. 개인의 특성에 따른 숲길걷기운동을 처방하기 위해 연령, 피로도 등에 따라 적합한 목표심박수를 제시하고, 이에 따라 실제 숲길에서 주 3회 운동하도록 한 후 선호하는 코스 유형 및 선택 요인을 도출하였다. 본 연구에는 만 19세부터 65세까지의 성인 50명이 참여하였다. 개인의 특성별 선호 코스 유형과 선택 요인을 분석하기 위해 교차분석을 사용하였으며, 운동 시 힘든 정도와 만족도를 분석하기 위해 비모수검정(Welch’s t-test, Friedman test)을 사용하였다. 개인의 특성별 선호 코스 분석 결과, 중장년층(만 42~65세)은 오르막이 가파른 코스를 선호하였으며, 청년층(만 19세~24세)은 비교적 오르막이 완만한 코스를 선호하였다. 코스 선택 요인 분석 결과, 청년층과 꾸준히 운동하지 않는 사람이 코스 선택 시 오르막을 고려하는 것으로 나타났다. 운동 시 힘든 정도와 만족도 분석 결과, 중장년층이 청년층보다 운동 시 덜 힘들었으며 숲길걷기운동 강도에 만족하였다고 응답하였다. 결론적으로, 본 연구에서 제시한 숲길걷기운동처방 결과, 연령층에 따라 선호 코스가 다르게 나타났으며, 중장년층이 청년층보다 더 난이도 높은 코스를 선호함과 동시에 운동 시 힘든 정도를 긍정적으로 평가한 것을 확인하였다. The aim of this study is to deduce the algorithm of forest exercise prescription based on individual characteristics and analyze preferred courses according to those characteristics, in order to provide fundamental data for forest exercise as a safe and effective health management activity. The participants were prescribed target heart rate suitable for their individual characteristics such as gender and age. After exercising three times a week on actual forest trails, they were asked to complete a questionnaire regarding their preferred course and considerations. 50 adults aged 19 to 65 participated. Cross-analysis was conducted to analyze preferred courses and considerations based on individual characteristics. Welch’s t-test and Friedman test were conducted to analyze the intensity of exercise difficulty and satisfaction with exercise prescriptions. The result of the analysis of preferred course based on individual characteristics, the middle aged group(42 to 65 years) preferred course with steep uphill and gentle downhill, while the youth aged group(19 to 24) preferred course with gentle uphill and steep downhill. The youth aged group and non-steady exercisers considered uphill sections. The middle aged group reported less difficulty during forest exercising and more satisfaction with the forest exercise prescription than youth aged group. In this study, the middle aged group showed higher proportion of individuals who exercised regularly and non-alcohol consumption compared to the youth aged group. This suggests the middle aged group has the strong intention to improve their health. Therefore, as a result of the forest exercise prescription in this study, it was confirmed that middle aged group prefer the course with higher difficulty than youth aged group, while also being positive in the degree of difficulty of exercising and satisfaction.

中·臺·美의 금문도와 대만해협에 대한 인식변화 ― 냉전시기 대만해협을 둘러싼 중국·대만·미국 간 갈등과 대립의 전개양상을 중심으로

이가영 대한중국학회 2022 중국학 Vol.78 No.-

During the Cold War, the Taiwan Strait differs in role and character depending on the political situation of China and Taiwan at home and abroad, and becomes a key stage for the process of changing the Cold War type in East Asia. In the Battle of Guningtou, which took place after the establishment of the People‘s Republic of China, the Taiwan Strait played a role as a front line for the power fight between China and Taiwan. However, as World War II ended and East Asia divided into communist and free camps, the Taiwan Strait became a demarcation line that divides the East Asian Cold War. After that, the United States participated in the first Taiwan Strait crisis in earnest, the Taiwan Strait was transformed into a battlefield for the expansion of the Cold War territory. However, as the expansion of armed conflicts poses a threat to security and safety in the Pacific region, the Taiwan Strait becomes a fence for a camp blockade that stabilizes conflicts between the two. However, as China launched the second Taiwan Strait crisis under the banner of supporting the Middle East Revolution and liberating Taiwan, the Taiwan Strait turned into a heated space again. And as the talks between China and the United States progress, the Taiwan Strait turns into a venue for ideological warfare between China and Taiwan.
