김나영,홍영미,정조원,김남수,노정일,송영환 대한소아청소년과학회 2013 Clinical and Experimental Pediatrics (CEP) Vol.56 No.12

Purpose: Obesity is an important risk factor for hypertension in adolescents. We investigated the relationship of obesity-related indices (body mass index [BMI], waist-to-height ratio [WHR], and body fat percentage [%BF]) with blood pressure and the hemodynamic determinants of blood pressure in Korean adolescents. Methods: In 2008, 565 adolescents, aged 12–16 years, were examined. The %BF of the participants was measured by bioelectrical impedance analysis. Echocardiography and brachial artery pulse tracing were used to estimate the stroke volume (SV), cardiac output (CO), total vascular resistance (TVR), and total arterial compliance (TAC). Results: We noted that BMI, WHR, and %BF were positively correlated with systolic blood pressure (SBP) and diastolic blood pressure (DBP). The positive correlation between BMI and blood pressure (SBP and DBP) persisted after adjustment for WHR and %BF. However, after adjustment for BMI, the positive associations between blood pressure (SBP and DBP) and WHR as well as %BF, were not noted. With regard to the hemodynamic factors, BMI, but not WHR and %BF, was an independent positive factor correlated with SV and CO. TVR had an independent negative association with BMI; however, it was not associated with WHR or %BF. Moreover, we noted that BMI, WHR, and %BF did not affect TAC. Conclusion: In Korean adolescents, BMI had an independent positive correlation with SBP and DBP,possibly because of its effects on SV, CO, and TVR. WHR and %BF are believed to indirectly affect SBP and DBP through changes in BMI.

한국인 원자폭탄 피해자 지원 조례 분석 - 길버트와 테렐의 정책분석모형을 중심으로-

김나영,유영미 가천대학교 법학연구소 2020 가천법학 Vol.13 No.1

원폭투하 당시 일본에 거주하여 영향을 받은 한국인 원폭피해자 문제는 오랫동안 외면 받았다. 생존자들의 지속적인 요구를 통해 최근에서야 특별법과 조례 제정이 이루어졌다. 본 연구에서는 길버트와 테렐의 정책 분석모형의 네 가지 차원인 대상, 급여, 전달, 재정에 따라 원폭피해자 지원 조례를 분석하였다. 그 결과 대상차원에서 원폭의 유전성을 인정하고 있었고, 급여는 실태조사와 추모 등 기념사업과 같은 피해자들의 욕구를 적절히 반영하지 않았다. 전달에 있어서 피해자 네트워크가 자체적으로 활발하게 활동하고 있으나, 정작 지원은 이루어지지 않고 있으며 재정차원에서는 일본정부로부터 재원이 제공되면서 예산확보가 의료비에 국한되어 있다. 이러한 문제해결을 위해 조례 내에 실태조사, 추모에 해당하는 항을 별도 제정하고 당사자의 욕구를 실질적으로 지원할 수 있도록 구체적으로 개정되어야 하며 조례 제·개정 시 원폭피해자들의 참여와 행동의 영향력을 인정하고 지원해야 한다. The problem of Korean atomic bomb victims who lived in Japan during the Japanese colonial period was ignored for a long time. Recently, through the continuous demands of survivors, special laws and ordinances were enacted. Therefore this study analyzed the ordinances by using political analysis frameworks of Gilbert and Terrell: allocation, benefits, service delivery system, and finance. As a result, the genetics of atomic bombs were recognized at the target level, however, the benefits did not properly reflect the needs of victims such as the memorial projects and research on the actual condition. In terms of service delivery system, the victim network is active in itself, but there is no support. In terms of finance, the financial resources are provided by the Japanese government, so the budget is limited to medical expenses. In order to solve these problems, it is necessary to establish separate terms corresponding to survey status and the memorials. within the ordinance and to revise them in detail so that they can support the needs of the parties. In addition, the influence of participation and behavior of atomic bomb victims should be recognized and supported in the ordinance.

뇌졸중 후 섬망의 진단과 치료

김나영,김용욱 대한뇌신경재활학회 2015 뇌신경재활 Vol.8 No.2

Delirium is an acute disturbance of consciousness and cognition with fluctuating course over a short period of time. Recognition of delirium in post-stroke patients is important because of its association with a longer stay in the hospital, a poor functional outcome, an increased risk of deteriorated cognition, and a higher mortality rate. It is occasionally under-recognized due to the fluctuating course and the neurological deficits that are caused by the stroke. Disturbance of several neurotransmitter systems including not only acetylcholine and dopamine but also serotonin, noradrenaline and gamma amino butyric acid have been implicated for the possible pathophysiology of delirium. Numerous potential precipitating and predisposing factors have been proposed such as comorbid condition, age, acute medical insults and environmental issues. In view of the complex multifactorial causes of delirium, multicomponent non-pharmacological approaches for risk factors are the most effective strategy for prevention of delirium. Preventive interventions such as frequent reorientation, early and recurrent mobilization, pain management, adequate nutrition and hydration, reducing sensory impairments, and ensuring proper sleep patterns have all been shown to reduce the incidence of delirium, regardless of the care environment. Pharmacologic interventions and physical restraints should be reserved for patients who are a threat to their own safety or the safety of others. This review describes epidemiology, pathophysiology, risk factors, diagnostic methods, and management of delirium in post-stroke patients.

Effects of Types of Voice-Based Chat on EFL Students’ Negotiation of Meaning According to Proficiency Levels

김나영 한국영어교육학회 2017 ENGLISH TEACHING(영어교육) Vol.72 No.1

The current study explores the effects of different types of voice-based chat on EFL students’ negotiation of meaning according to proficiency levels. Participants included 123 Korean university students of English. They were divided into two voice-based chat groups: student-student voice-based chat and student-chatterbot voice-based chat. The experiment was administered throughout one semester, 16 weeks. Negotiation of meaning evident in the chats was coded for confirmation check, comprehension check, clarification requests, repetition, and reformulation, and was measured by counting the number of meaning negotiation moves. Important findings were as follows: Firstly, there were significant differences between the first chat and the last chat. The mean frequencies of negotiation moves at all proficiency levels positively changed over time as a result of participating in student-chatterbot voice-based chat. Particulalry, student-chatterbot voice-based chat, as compared to student-student voice-based chat, allowed students to use more negotiation strategies, and the strategies used in the chats also appeared to be different according to the students’ proficiency levels. Lastly, positive perceptions of voice-based chat were observed at all proficiency levels. This study provides empirical evidence to substantiate the effects of voice-based chatterbots in oral interaction. Based on the findings, pedagogical implications are made on the effective implementation of voice-based chatterbots in EFL contexts.

김나영,정현희 한국아동발달지원연구소 2012 임상미술심리연구 Vol.2 No.1

본 연구는 미술치료사의 개인배경(연령, 결혼여부, 미술치료교육기관, 경력, 학력, 근무 기관)에 따라 심리적 소진과 자아탄력성에 차이가 있는가에 대해 알아보고자 하였다. 연 구대상은 미술치료사 107명이다. 연구척도는 Maslach와 Jackson(1981)의 심리적 소진 질 문지와 Block(1961)의 척도를 Klohnen(1996)이 수정한 자아탄력성 질문지였다. 자료 분석 은 t-test, one-way ANOVA를 실시하였다. 연구결과는 다음과 같다. 첫째, 미술치료사의 자아탄력성은 개인배경에 따라 차이가 나타나지 않았다. 단지 자아탄력성의 하위변인인 대인관계효율성과 낙관적태도가 근무기관에 따라 차이가 나타났다. 둘째, 미술치료사의 개인배경에 따라 심리적 소진은 차이가 나타나지 않았다. 단지 심리적 소진의 하위변인인 정서소모는 결혼여부에서, 개인적성취감감소는 결혼여부와 근무기관에 따라 유의미한 차이를 나타냈다. This study was to investigate the differences in the art therapist's ego-resiliency & psychological burnout according to the demographic variables(age, marital status, education institute, career, education level, work place). The subjects were 107 art therapists. Psychological burnout scale by Maslach and Jackson(1981) & ego-resiliencey scale developed by Block(1961) and revised by Klohnen(1996) were used. The data were analyzed by t-test, one-way ANOVA. The results were as follows. First, there were no differences in ego-resiliency according to the demographic variables. Only there were differences in efficiency of personal relations & in optimistic attitudes of the ego-resiliency according to work place. Second, there were no differences in psychological burnout according to the demographic variables. Only art-therapists showed differences in emotional exhaustion according to marital status & in sense of personal accomplishment according to marital status and work places.

The Effects of Online Planning on CAF in L2 Spoken and Written Performance

김나영 한국영어교육학회 2018 ENGLISH TEACHING(영어교육) Vol.73 No.3

The purpose of this study is to investigate the effects of no planning and online planning on complexity, accuracy, and fluency (CAF) in L2 spoken and written tasks. The study was designed into 2x2 with two independent variables: planning conditions (no planning and online planning) and task modality (speaking and writing). First, 80 Korean EFL undergraduates performed two tasks in a laboratory setting: a proficiency-assigning narrative spoken task and a randomly assigned main task. The main task had four different conditions: no planning in speaking, online planning in speaking, no planning in writing, and online planning in writing. The participants’ spoken and written performances were measured and analyzed for syntactic complexity, accuracy, and fluency. The findings demonstrated that the no planning (NP) group improved accuracy and fluency significantly more than the online planning (OP) group in the spoken task and that the NP group improved their fluency more than the OP group in the written task. Additionally, in both planning conditions, the written task increased accuracy more than the spoken task, whereas the spoken task increased fluency more than the written task. It is hoped that these findings will facilitate understanding of the supportive role of planning in task manipulation in terms of L2 learners’ limited attentional resources and its relationship with linguistic performance.

Effects of Different Types of Voice-Chat Activities on Korean EFL Students’ Fluency, Accuracy, and Complexity

김나영 영상영어교육학회 2017 영상영어교육 (STEM journal) Vol.18 No.1

The present study investigated the effects of two different types of voice-chat activities on fluency, accuracy, and complexity of Korean EFL students’ speaking performance. Participants of the current study were 181 students of English as a foreign language from a university in Korea. They joined in three different voice-chat activities (voice-chat with classmates, voice-chat with robots, and control). During an experimental period of sixteen weeks, participants had a voice-chat with either classmates or robots. Major findings were as follows: Firstly, regarding the changes in speaking performance, findings reveal that participants produced better output in fluency and accuracy, as a result of engaging in both voice-chat activities. Secondly, concerning the group differences in speaking performance, results indicate that voice-chat activities with robots had statistically significant impacts on fluency and accuracy, compared to the control group. Thirdly, in an interview, participants in both experimental groups showed positive attitudes towards learning English as a foreign language. They were able to reduce their stress and anxiety, while increasing their interest in English language learning, to be an outcome of taking part in voice-chat activities. Based on these findings, pedagogical implications are discussed for the effective use of voice-chat activities in EFL settings.
