인터넷의 발달과 뉴스매체의 포섭 비용의 변화

양상우(Yang, Sangwoo),한순구(Hahn, Sunku) 연세대학교 동서문제연구원 2017 동서연구 Vol.29 No.1

사회 구성원 대다수는 정직하고 진실한 뉴스를 원하지만, 어느 사회에나 경제력이나 물리력을 동원해 자신에게 유리한 쪽으로 뉴스매체를 포섭하려는 이들이 있기 마련이 다. 이런 뉴스매체 포섭과 관련한 대표적 견해는 ‘매체 수’(또는 ‘경쟁’)가 늘수록 포섭이 어려워진다는 것이다. 이 견해에 따르면 인터넷의 발달로 온라인 뉴스매체의 수가 크게 늘었으므로, 뉴스매체 포섭은 그만큼 어려워져야 한다. 하지만, 이 연구는 온라인 매체의 발달에 따른 뉴스매체의 수입 감소로 오히려 매체 포섭이 쉬워질 수 있음을 보여주고 있다. 인터넷의 등장으로 변모한 뉴스 시장에서, 이처럼 증가하는 뉴스매체 포섭의 가능성을 줄이려면 온라인 뉴스 소비량에 따른 의미 있는 보상을 뉴스매체가 얻을 수 있는 ‘시장 구조’가 필요하다. Most of news consumers want to know the truth. However, there always exist people or organizations who want to manipulate news favorable to them. The typical view of media capture was that if the number of media increases, it would be harder to capture media. In this point of view, sudden increase of news media after the introduction of the internet should have reduced the media captures. However, our model shows that media capture may increase even when the number of media increases when the introduction of internet decreases the revenue of media from exclusive news report. Therefore, to reduce harmful consequences of media capture in the news market, the news firms should be able to get “enough” revenue from the online news consumption.

Objective-We aimed to identify depressive symptom profiles that indicated the presence of depressive disorder and present optimal cut-off sub-scores for depressive symptom profiles for detecting depressive disorder in elderly subjects with chronic physical diseases including diabetes, chronic obstructive pulmonary disease/asthma, and coronary artery disease, using the Patient Health Questionnaire-9 (PHQ-9). Methods-Two hundred and thirty-one elderly patients with chronic physical diseases were recruited consecutively from a university-affiliated general hospital in South Korea. Results-Greater severities of all 9 depressive symptoms in the PHQ-9 were presented in those with depressive disorder rather than those without depressive disorder. A binary logistic regression modeling presented that little interest [adjusted odds ratio (aOR)=4.648, p<0.001], reduced/increased sleep (aOR=3.269, p<0.001), psychomotor retardation/agitation (aOR=2.243, p=0.004), and concentration problem (aOR=16.116, p<0.001) were independently associated with increased likelihood of having depressive disorder. Receiver operating characteristics (ROC) curve analysis presented that the optimal cut-off value of score on the items for little interest, reduced/increased sleep, psychomotor retardation/agitation and concentration problem (PHQ-9) for detecting depressive disorder was 4 with 61.9% of sensitivity and 91.5% of specificity [area under curve (AUC)=0.937, p<0.001]. Conclusion-Our findings suggested that the diagnostic weighting of little interest, reduced/increased sleep, psychomotor retardation/agitation, and concentration problem is needed to detect depressive disorder among the elderly patients with chronic physical diseases.

본 연구는 한국의 재난심리지원체계를 개선하기 위해 세월호 참사 관련 심리지원서비스 제공자들의 시각을 통하여 기존 지원체계의 한계와 보완점을 확인하는 것이 목적이다. 이를 위해 세월호 참사 당시 심리지원을 담당했던 기관 중 3개 기관(안산시 정신건강증진센터, 국립서울병원, 안산정신건강트라우마센터)의 실무자 31명을 대상으로 심층면접을 실시하였고, 이를 녹취하여 내용분석하였다. 분석결과, 39개 개념이 도출되었고, 개념들로부터 14개 하위범주가 추출되었으며, 하위범주들은 6개 상위차원으로 기술되었다. 구체적으로 ① 행정체계(관계 부처들)와 수직적 관계에서 경험한 어려움, ② 집행체계 간 수평적 관계에서 경험한 어려움, ③ 실무자가 속한 기관에서 발생한 어려움, ④ 유가족을 지원하는 과정에서 경험한 어려움, ⑤ 실무자 개인차원에서 경험한 어려움, ⑥ 세월호 참사의 특수성 때문에 경험한 어려움들이었다. 본 연구결과를 바탕으로 실무자들의 보고를 통한 국내 재난심리지원체계의 한계점들을 극복하기 위해서 요구되는 점들을 제안하였다. The Sewol Ferry accident in April of 2014 is considered one of the biggest tragedies in modern Korean history since most victims among the 304 deceased were high school students who were going on a field trip. The Sewol Ferry accident also became a milestone in changing the national disaster response and recovery system in Korea. New laws and policies are being suggested and developed currently. We interviewed 31 crisis responders from three emergency mental health service organizations which worked on the scene immediately after the Sewol Ferry accident with the purpose of finding out how the existing emergency mental health service system actually functioned and what could be improved. After an in-depth interview, we analyzed the data using the Qualitative Content Analysis(QCA) method. Based on our data, we suggested an integrated model of disaster response systems that could be included in the new policies in Korea.

본 연구는 재난심리지원 실무자의 보고를 통해 초기 대응단계에서 유가족이 경험한 어려움이 무엇이었으며, 초기에 제공된 재난심리지원 서비스에 대해 유가족의 경험이 어떠했는지, 이를 통해 유가족에게 도움이 된 것과 한계점은 무엇인지를 살펴보는 것을 목표로 하였다. 그리고 그 과정에서 유가족이 서비스의 어떤 측면을 긍정적으로 보았는지, 실무자는 어떤 요인을 회복과정의 촉진요인으로 인식하는지를 발견하고자 했다. 이를 위해 세월호 참사 직후 유가족에게 초기 재난심리지원 서비스를 제공했던 실무자 35명의 인터뷰자료를 질적으로 분석하였다. 분석결과, 57개 개념이 도출되었고 개념으로부터 16개 하위범주가 추출되었으며 하위범주는 6개 상위차원으로 기술되었다. 본 연구결과를 바탕으로 세월호 참사 이후 유가족의 초기 심리사회적 반응과 심리지원 서비스 제공을 통한 변화과정을 구조화하였으며 논의를 통해 차후 재난심리지원을 위한 실무자 교육이나 서비스 평가, 재난심리지원 정책 수립단계에서 중요하게 고려해야 할 요소를 제안하였다. This study aims to explore psycho-social experiences of the bereaved family during the initial response stage and how they progressed through the disaster support services by interviewing the disaster support workers. Total of thirty five responders who provided psycho-social support services after the ‘Sewol’ Ferry accident were interviewed indepth. We analyzed the data using the Qualitative Content Analysis (QCA) method. As a result, 57 meaningful concepts were derived from 57 statements, and fall into 16 categories with 6 dimensions. Based on these results of this study, we suggested the changing process an integrated model of the bereaved family’s grief and through carly psycho-social reactions to the disaster support service after the Sewol disaster. Finally, this study recommends important components in decision-making for disaster psychosocial support, its practitioner training and service evaluation. Practical implications for disaster policy issue, training program for disaster workers, support system evaluation as well as suggestions for further research were discussed.

HwaYoung Lee,ChaeKeun Oh,ByungJoo Ham,HunSoo Chang,JongWoo Paik,EunSoo Won,SangWoo Hahn,SeHoon Shim,YoungJoon Kwon,HeeYeon Jung,MinSoo Lee 대한신경정신의학회 2013 PSYCHIATRY INVESTIGATION Vol.10 No.2

Objective-Activation of one or more serotonin (5-HT) receptors may play a role in mediating the antidepressant effects of serotonergic antidepressants. The serotonin 2C (5HT 2C) receptor is known to be associated with antidepressant action and weight gain. We sought to determine whether the 5-HTR 2C receptor -759C/T polymorphism was associated with weight gain and treatment response to mirtazapine in major depressive disorder (MDD) patients. Methods-The 5-HT 2C receptor -759C/T polymorphism was analyzed in 323 MDD patients. All patients were evaluated using the 21-item Hamilton Depression Rating Scale at the beginning of the study and at 1, 2, 4, and 8 weeks of mirtazapine treatment. Results-There was no significant difference in the 5-HT 2C receptor -759C/T genotype distribution between responder and non-responder groups. The 5-HT 2C receptor -759C/T polymorphism was not associated with weight change over time after mirtazapine administration. Conclusion-The 5-HT 2C receptor -759C/T polymorphism does not appear to be a predictor of treatment response to mirtazapine. This polymorphism was not associated with weight change after 8 weeks of mirtazapine treatment. Further investigation on other polymorphisms of the 5-HT 2C gene is required to determine whether the 5-HT 2C gene influences treatment response and weight change after mirtazapine administration in patients with major depressive disorder.

Objectives We aimed to identify the neuroimaging marker for prediction of the use of atypical antipsychotics (AAP) in dementia patients. Methods From April 2010 to March 2013, 31 patients who were diagnosed as dementia at the psychiatric department of Soonchunhyang University Hospital, completed the brain magnetic resonance imaging scan and cognitive test for dementia. Ten patients were treated with AAP for the improvement of behavioral and psychological symptoms of dementia (BPSD) and the other 21patients were not. Using T1 weighted and Fluid Attenuated Inversion Recovery (FLAIR) images of brain, areas of white matter (WM), gray matter (GM), cerebrospinal fluid (CSF) and white matter hyperintensities (WMH) have been segmented and measured. Multivariate logistic regression models were applied for assessment of association between AAP use and the GM/WM ratio, the WMH/whole brain (GM + WM + CSF) ratio. Results There was a significant association between AAP use and the GM/WM ratio (odds ratio, OR = 1.18, 95% confidence interval, CI 1.01-1.38, p = 0.037), while there was no association between AAP use and the WMH/whole brain ratio (OR = 0.82, 95% CI 0.27-2.48, p = 0.73). Conclusions The GM/WM ratio could be a biological marker for the prediction of AAP use and BPSD in patients with dementia. It was more likely to increase as dementia progress since atrophy of WM was more prominent than that of GM over aging.
