Background: Two hundred and fifty 11th grade students and teachers from Danwon High School drowned, during a school trip, in the Sewol Ferry Disaster. The goal of this study was to investigate the experiences of the psychiatrists who volunteered and provided psychiatric services to the students at Danwon High School. Methods: From the second day to the 138th day after the disaster, pro bono psychiatrists provided post-disaster interventions to the 10th and 12th-grade Danwon High School students who did not attend the trip. Officially, 167 psychiatrists conducted outreach in approximately 550 encounters. The study questionnaires were distributed retrospectively to psychiatric volunteers who conducted outreach at Danwon High School. We surveyed the pro bono psychiatrists about their experiences, including the students' chief complaints, psychiatric problems, clinical diagnoses, and psychiatrists' treatment recommendations. Results: We reached 72 (43.1%) of the 167 volunteers, and they reported on 212 (38.6%) of the 550 encounters. The common chief complaints were mental health problems, companion problems, and family problems. The most frequent psychiatric symptoms were anxiety (76.89%), depressive mood (51.42%), and concentration difficulty (50.94%). The most frequent clinical diagnoses of the students were normal reaction (41.04%), acute stress disorder (24.53%), adjustment disorder (17.92%), anxiety disorders (9.43%), and posttraumatic stress disorder (6.60%). More than half of the students needed “additional counseling/therapy” (41.04%) or “referral to psychiatric treatment” (14.15%). Conclusion: During the acute aftermath of the Sewol Ferry Disaster, volunteer psychiatrists were able to provide services. These services included psychiatric assessments, crisis counseling, psychological first aid, and referrals for ongoing care. More than half of the students were perceived to have a psychiatric diagnosis,and a substantial proportion of students needed further treatment. Future research should focus on the short- and long-term effects of psychiatric interventions and the characterization of post-disaster mental health needs and service provision patterns.
Synthesis of coreeshell nanoparticles with a Pt nanoparticle core and a silica shell
오종길,김한성 한국물리학회 2013 Current Applied Physics Vol.13 No.1
A method to prepare a coreeshell structure consisting of a Pt metal core coated with a silica shell (Pt(in) SiO2) is described herein. A silica shell was grown on poly(vinylpyrrolidone) (PVP)-stabilized Pt nanoparticles 2e3 nm in size through hydrolysis and condensation reactions of tetraethyl orthosilicate (TEOS) in a water/ethanol mixture with ammonia as a catalyst. This process requires precise control of the reaction conditions to avoid the formation of silica particles containing multiple Pt cores and core-free silica. The length of PVP molecules, water content, concentration of ammonia and Pt nanoparticles in solution were found to significantly influence the coreeshell structure. By optimizing these parameters, it was possible to prepare coreeshell particles each containing a single Pt nanoparticle with a silica layer coating approximately 10 nm thick.

Kenzo Tnage's work reflects and crystallizes the changing political and economical circumstances of Japan in a quarter century from the nationalism of World War Ⅱ, through defeat and reconstruction, to the renewed search for national identity and growth in confidence. Its possible to divide his career into two parts, whose major interests are the synthesis of Japanese traditions and Modern architecture and the realization of a Metabolist vision of the city. Therefore, this study aims to analyze the Japanese traditions and Modernity in Kenzo Tange's Architecture.

Objectives : Screening, Brief Intervention, and Referral to Treatment (SBIRT) is a good example of community involvement model for substance and behavior addiction. The purpose of this study is to investigate the effectiveness of the SBIRT model for intervention in schools and local child care centers. Methods: From March to October 2017, we surveyed 3,937 students attending schools in Nowon-gu, who were smartphone users. Among them, 180 students were regarded as a high-risk group for addiction and were enrolled in a short-term group intervention program with the permission of their parents. Results : After a short-term intervention program, a significant decrease in the smartphone dependence scale from 16.72 to 14.93 was observed. Male students showed a significant decrease from 17.53 to 15.12, but female students’ scores revealed an insignificant decrease from 15.73 to 14.71. The effect of intervention by the school showed a significant decrease from 16.22 to 14.31 in elementary school students. A significant decrease was also present in middle school students whose scores declined from 18.50 to 15.88. Conclusion: We have demonstrated the efficacy of the SBIRT model in the local community in order to introduce evidence-based intervention program. In the future, it would be necessary to induce the healthy use of smartphones in adolescents by appropriate intervention through continuous policy-making and funding

DMFC(direct methanol fuel cell)는 액체연료의 이동과 저장의 용이성 때문에 이동용 장치를 위한 전원공급 장치로서 오랫동안 관심을 받아왔다. 하지만 methanol crossover는 DMFC의 상용화 이전에 해결해야 할 문제이다. 이를 위해 많은 분야에서 연구가 진행되고 있고, 그중에서 methanol에 저항성을 가진 촉매의 개발에 활발히 연구가 진행되고 있다. 본 연구에서는, 표연개질 된 PtCo/C 촉매를 사용하여 메탄올에 저항성을 가진 촉매를 합성하였다. 합성된 촉매의 size와 morphology를 알아보기 위해 transmission electron microscopy (TEM)를 사용하였다. 또한 methanol 존재 하에 산소환원반응의 activity를 알아보기 위해 Rotating ring disk electrode(RRDE) test를 하였고, MEA를 제작하여 full cell test도 병행하였다.
전기화학적 분석을 통한 연료 전지용 촉매의 성능 저하 요인의 평가

Polymer Electrolyte Membrane fuel cell(PEMFC)의 촉매로는 주로 carbon을 지지체로 사용한 Pt/C 흑은 Pt alloy/C을 사용하게 된다. 이때 PEMFC의 상용화에 있어 촉매의 안정성은 상용화 실현에 있어 중요한 요인으로 인식되고 있다. 촉매의 성능 저하는 Pt의 활성 면적(Active surface area)의 감소가 원인으로 얘기되어 지고 있으며 이는 지지체로 사용한 탄소에 나노 크기로 분산되어 있던 Pt 입자가 커지면서 활성 면적이 감소되어 지기 때문이다. 이번 연구에서는 상용 Pt/C를 사용하여 Cyclic Voltammetry(CV)의 장기간 운전 및 다양한 조건 변화를 통하여 Pt입자의 크기 증가에 미치는 요인에 대한 연구를 진행하였다. 이와 더불어 Linear Sweep Voltammety(LSV), TEM, 등을 통한 분석이 진행되었다.

연구목적 일 도시지역의 독거 노인을 대상으로 노인 우울증상 및 자살 경향성 정도를 파악하고 이에 영향을 끼치는 인구사회적 변인들을 파악하고자 하였다. 방 법 2009년 서울시 도봉구에 거주하는 589명의 65세 이상의 독거노인을 대상으로한국형 축약형 노인 우울증 척도, 자살 경향성 척도, 인구사회학적 변인들을 조사하였다. 수집된 정보들을 바탕으로 통계적 분석을 시행하였다. 결 과 독거노인의 평균연령은 75.69세(표준편차 6.17), 학력은 무학 40.1%, 초등학교 졸업 31.4%, 고등학교 졸업 12.9%, 중학교 졸업 11.7%, 대학교 졸업이상 3.2% 순이었다. 우울증상의 위험성을 높이는 변인들에는 종교 없음, 우울증 과거력 있음, 신체질환 병력 있음, 활동단체 없음, 가족에 대한 만족도가 낮음의 경우가 있었다. 자살 경향성에서는 종교 없음, 우울증 과거력 있음, 가족에 대한 만족도가 낮음이 영향을 줄 수 있는 변수였다. 특히 낮은 가족에 대한 만족도 및 우울증 과거력이 있음의 경우는 독거노인의 우울증상 및 자살 경향성을 크게 높일 수 있는 변인들로 나타났다. 결 론 독거 노인의 우울증 병력, 가족 만족도, 사회적 지지체계 등과 같은 위험 변인들에 대한 평가 및 개입이 노인 우울증 및 자살 예방에 도움이 될 것으로 보인다. Objectives: To understand the risk factors of demographic data in geriatric depression scale, and suicidality among in elderly who live alone at one urban region. Methods:In 2009, 589 elderly who live alone(age${\geq}$65) were carried out a survey about several socio-demographic data, Korean version of the Geriatric Depression Scale(SGDS-K) and Suicidal Ideation Questionnaire (SIQ). Statistical analysis was performed for the collected data. Results: Mean age of elderly who live alone is 75.69(SD 6.17). 40.1% of participants uneducated, 31.4% graduate from elementary school, 12.9% graduate from high school, 11.7% graduate from middle school, 3.2% graduate from university. Religionless, having past history of depression or physical diseases, low subjective satisfaction of family situation, and not having any social group activity have significance to depressive symptoms of elderly who live alone. Having past history of depression, religionless, low subjective satisfaction of family situation have significance to suicidality. Especially, low subjective satisfaction of family situation and having past history of depression are powerful demographic factor both depressive symptoms and suicidality of elderly who live alone. Conclusions: When we take care elderly who live alone, we should consider many things, but especially the social support network such as family satisfaction and past history of depression for reducing or preventing their depression and suicide both elderly depression and suicide who live alone.
