타이타니움이소프로폭사이드의 가수분해로 타이타니아 졸용액을 제조하고 그 특성을 조사하였다. 용매, 촉매 그리고 물의 양이 졸의 안정도에 미치는 영향을 조\ulcorner고, 서로 다른 온도에서 졸용액의 전단점도를 측정하여 그 각각의 gel time을 알아보았다. 안정한 조성의 졸용액을 이용하여 광학적으로 투명하고 균일한 타이타니아 박막을 제조할 수 있었다. 또한, 이차비선형 활성단을 도입한 후에도 좋은 박막을 제조할 수 있었다. 제조된 박막은 3~5kV, 50~$100^{\circ}C$ 온도범위에서 코로나 분극처리 하였다. 632.8nm He-Ne레이저를 이용하여 측정한 일차 전기 광학 상수, $r_{33}$는 1.5~5pm/V로서 경시 안정성을 나타내었다. The polymeric titania sol was prepared via partial hydrolysis of titanium isopropoxide and its characteristics were investigated. The effect of solvent, catalyst and water content on the sol stability was investigated. The shear viscosities of sol solution at different temperatures were measured to determine the gel time. Employing the spin coating technique, optically clear and transparent titanium oxide thin film was fabricated. Even after doped with second-order nonlinear optical(NL0) active monomers, the film quality was maintained very homogeneous. The film was corona-poled under 3~ 5kV at 50~$100^{\circ}C$ range. The electro-optic coefficient, $r_{33}$ was measured to be 1.5~5pm/V using the wavelength, 632.8nm from He-Ne laser.

Objectives : Since mid-90s there have been numerous studies to understand and establish the concept of internet addiction as one of diagnostic classifications in psychiatry. Among them, many studies on the personality characteristics of internet addiction have been conducted. Recently, interests are expanding to temperament characteristics of internet addictors but the subjects have been limited to adolescents, In this study, the temperament characteristics of internet addiction in adults were investigated using Tridimensional Personality Questionnaire (TPQ). Methods : 430 participants (189 males, 241 females) answered the on-line and off-line questionnaires from January to December in 2005. Participants completed questionnaires on demography and the onset of internet use, Young's Internet Addiction Scale and Korean Contracted Version of Cloninger's Tridimensional Personality Questionnaire (TPQ). Rcsults : There were statistically significant differences in age, marital status, occupation, psychiatric history, smoking history, alcohol history and onset age of internet use among non-addiction, overuse and addiction groups by Young's scale. Of the TPQ items harm avoidance (HA) scores were significantly higher in addiction and overuse groups than non-addiction group. Reward dependence (RD) scores were significantly lower in addiction group than non-addiction group. Novelty seeking (NS) scores were significantly higher in addiction group than non-addiction group. Conclusion : This study suggests a significant difference of novelty seeking in temperament characteristics between adults and adolescents with internet addiction. Further studies are expected for profound understanding of internet addiction.

Decision making capacity(DMC) is an ability to understand appropriate information, remember, select and communicate to make a certain decision. It is a complex capacity needed to make vital decisions for health, safety, financial matters and residence of an individual. Studies have found that various functions of brain such as executive function, motivation for reward and punishment and metacognition are neuropsychological basis of DMC. However, present assessment of DMC is not yet reliable to estimate the complex function. Also, the present legal guardianship based on the assessment of DMC is triggering the social isolation of older adults with impaired DMC by vicarious authority of the legal guardians. In the near future supported decision making law rather than legal guardianship is expected to be a new system to support older adults with impaired DMC, so they are provided the maximum support to make decisions of their own. For the new system of supported decision making law, better assessment tools for DMC which can estimate specific real life functions are requested.

their combination for screening cognitive disorders in memory clinic setting. MethodsaaOne-hundred thirtytwo cognitively normal (CN), 136 mild cognitive impairment (MCI), and 546 dementia who visited the memory clinic in the Seoul National University Hospital underwent standardized clinical evaluation and comprehensive neuropsychological assessment. The Subjective Memory Complaints Questionnaire (SMCQ) and the Seoul Informant Report Questionnaire for Dementia (SIRQD) were used to assess subjective memory complaints and informant-reports for cognitive declines, respectively. ResultsaaBoth SMCQ and SIRQD showed significant screening ability for MCI, dementia, and overall cognitive disorder (CDall: MCI plus dementia) (screening accuracy: 60.1–94.6%). The combination of SMCQ and SIRQD (SMCQ+SIRQD) was found to have significantly better screening accuracy compared to SMCQ alone for any cognitive disorders. SMCQ+SIRQD also significantly improved screening accuracy of SIRQD alone for MCI and CDall, but not for dementia. ConclusionaaOur findings suggest that the combined information of both subjective memory complaints and informant-reports for cognitive declines can improve MCI screening by each individual information, while such combination appears not better than informant-reports in regard of dementia screening.

This article aims to review mental health problems among the elderly population caused by COVID-19 pandemic, and discuss the suggestions to prevent the problems.

‘광주외국인노동자건강센터’에 관한 민족지적 연구

임선진(Lim, Sunjin),김경학(Kim, Kyunghak) 전남대학교 글로벌디아스포라연구소 2014 디아스포라 연구 Vol.8 No.2

이 글은 ‘광주외국인노동자건강센터’(이하 ‘건강센터’)라는 건강 돌봄 공간이 광주지역 이주자와 돌봄 제공자간의 상호작용에 의한 돌봄 실천의 현장으로 작동하고 있는 바를 ‘건강센터’ 공간과 참여자들에 대한 참여관찰과 인터뷰 자료를 통해 민족지적 방식으로 기술하고 있다. ‘건강센터’의 형성과 운영을 비롯해 당초 의료지원 주요 대상이었던 미등록 이주노동자의 범주를 넘어 일반 이주자로 의료 지원 대상이 확장되는 과정에 대해 설명하고 있다. 더 나아가 이 연구는 ‘건강센터’에 참여하는 의료봉사자와 의료 수혜자의 시각에서 ‘건강센터’를 바라보는 인식을 살펴봄으로써 각자의 시각에서 센터에 부여하는 의미를 규명하고 있다. ‘건강센터’를 이용하는 이주자가 센터를 체류자격에 관계없이 오직 건강증진을 위한 활동에 관심 있는 의료지원 공간으로 인식하고 있다는 점은 ‘건강센터’와 같은 민간차원의 의료봉사 기관이 이주자에게 한국사회 생활을 할 수 있는 기초적인 안전장치로서 그 역할을 다하고 있음을 알 수 있게 한다. ‘Gwangju Migrant Worker’s Clinic Center’(hereafter ‘clinic center’) is a non-government medical care center which provides medical care for migrants regardless of legal status. At the beginning of ‘clinic center’, main target people of ‘clinic center’ were illegal migrant workers who have suffered from rights to medical care in Korea. This study aims at exploring scenarios of interactions between heath care providing volunteers like medical specialists and students and heath care receivers like migrant workers, international marriage migrants and their family members based on data collected from participant observation and in-depth interview. This study examines the meanings of ‘clinic center’ given by persons concerned, namely both heath care provers and care receivers. In order to get over the deficit of financial and medical supplies for improving quality and quantity of heath care of ‘clinic center’, it is necessary for central and regional governments to closely collaborate and assist with civil society organizations supporting medical rights to migrants.

스마트 폰의 등장과 모바일 인터넷을 제공함에 따라 휴대폰은 음성통신 수단이 아닌 웹을 통하여 서비스를 제공받는 도구 또는 각종 게임 및 응용 어플리케이션을 제공하는 놀이수단으로도 발전하였고, 이로 인하여 사용량도 증가하였다. 사용량의 급증으로 인하여 모바일 광고에 대한 업계의 관심도 증가 하였지만, 한정적인 출력화면에 의하여 제한적일 수밖에 없다. 이를 보완하기 위해, 본 논문에서는 기업의 로고 광고의 효과를 극대화 할 수 있는 안드로이드 기반 로고를 인식하는 증강현실 시스템을 제안 하였고, 이를 구현 하여 실 제폰에 탑재한 후 다양한 성능 분석을 하였다. 실험결과, 그 가능성은 확인하였지만 현하드웨어 성능으로는 실시간으로 지원하기에는 역부족임을 알 수 있었다.

애니메이션 여성 캐릭터의 변화에 따른 여성에 대한 사회적 관념의 변화

임선진(Seon-Jin Lim),이지훈(Ji-Hun Lee) 한국엔터테인먼트산업학회 2016 한국엔터테인먼트산업학회 학술대회 논문집 Vol.2016 No.5

애니메이션은 어릴 적 가장 접하기 쉬운 문화 매체 중 하나이며, 이러한 애니메이션의 캐릭터는 젠더 정체성을 형성하는 데 영향을 준다. 그 중 디즈니 애니메이션은 장르가 다양하고 여성 캐릭터의 정체성 변화를 알 수 있다. 1937년 제작된 ‘백설 공주와 일곱 난쟁이’에서 백설 공주처럼 순종적이고 가정적이며 왕자와의 결혼으로 인해 자신의 정체성을 들어내는 캐릭터에서부터 1998년 ‘뮬란’에서 뮬란처럼 자기주장이 강하고 지혜로우며 영웅의 모습을 보여주는 캐릭터까지에 이르렀다. 하지만, 결말에서는 늘 남성 캐릭터와 만나 이루어지는 부분을 강조하고 있다. 그에 비해, 2013년에 제작된 ‘겨울 왕국’은 남성 캐릭터가 등장함에도 불구하고 결론적으로는 자매의 사랑으로 마무리가 지어지며 행복의 끝이 꼭 결혼이 아니라는 것을 이야기한다. 이러한 여성 캐릭터의 정체성 변화로 인해 전통적인 여성관과 현대적인 여성관에게 어떠한 영향을 끼치는지에 대해 조사하고자 한다.

CADASIL의 정신과적 증상 발현에 대한 고찰

임선진 ( Seon Jin Yim ) 한국정신병리진단분류학회 2020 精神病理學 Vol.24 No.2

Cerebral autosomal dominant arteriopathy with subcortical infarcts(CADASIL) is an autosomal-dominantly inherited small artery disease characterized by variable neurologic symptoms and typical brain MRI findings. Psychiatric symptoms and cognitive decline are relatively common symptoms observed in CADASIL, and mood disturbance is second most common initial symptom of CADASIL in patients of 50 or older. However, CADASIL is underdiagnosed by psychiatric experts. In this article we review and discuss about variable psychiatric symptoms of CADASIL to promote more precise diagnosis in psychiatric clinics.

이황빈,임선진,유남희 대한우울조울병학회 2014 우울조울병 Vol.12 No.3

Objectives: We evaluated the clinical characteristics, longitudinal courses and the cycle-length patterns of patients with bipolar I disorder. Methods: We assessed one hundred twenty patients (n=120) with bipolar I disorder by retrospective medical records review. Single manic, continuous and rapid cycling courses were excluded. Results: There were some differences in longitudinal course of patients with bipolar I disorder according to gender and the index episode. Manic onsets were more frequent in men (53.4%), whereas depressive onsets were more frequent in women (51.6%). The age of onset in mixed or hypomanic onset group (16.0±0 yrs, 20.0±2.4 yrs) were younger than in manic (24.6±7.3 yrs) or depressive (25.7±7.5 yrs) onset group. Initial manic episode was more related to later mania, whereas initial depressive episode was more related to later depression. Consistent findings of progressive shortening of cycle were not observed. Conclusion: The type of the index episode appears to have gender-related clinical differences. Age of onset is different according to the index episode. The index episode seems to influence the predominant polarity of the bipolar I disorder in each individual patient. The cycle-length patterns were not progressive cycling over time, nor gradual lengthening in later episodes in this study.
