이소현,이수정 한국유아특수교육학회 2012 유아특수교육연구 Vol.12 No.2

자폐 범주성 장애 영유아 관련 연구에 대한 관심은 최근에 들어서 급격하게 증가하고 있다. 이는 전 세계적으로 보고되고 있는 출현율 상승과 관련될 뿐만 아니라 장애의 특성상 조기발견의 가능성 및 지원의 필요성이 강조되고 있기 때문인 것으로 추측해볼 수 있다. 그러나 해외에서 이루어지고 있는 연구에 비해서 국내 연구는 그 양이나 질적인 측면에서 아직까지 초기 단계에 머무르고 있다. 따라서 본 연구에서는 국내 자폐 범주성 장애 영유아 관련 연구의 동향을 살펴보고 이를 기반으로 관련 연구 현장에서 직면하고 있는 과제에 대하여 논의함으로써 앞으로 수행될 연구의 발전 방향을 제시하고 실질적인 활성화를 촉진하기 위한 목적으로 수행되었다. 이를 위하여 2001년부터 2010년까지 10년 동안 이루어진 자폐 범주성 장애 영유아 관련 연구를 검색하였으며, 그 결과 총 137개의 논문을 분석대상으로 선정하여 전반적인 연구 동향을 알아보았다. 또한 분석 대상 논문 중 자폐 범주성 장애 영유아를 대상으로 중재를 실시하고 그 성과를 검증하기 위하여 수행된 실험연구 57편에 대한 추가 분석을 실시하였다. 분석 결과를 근거로 자폐 범주성 장애 영유아 관련 국내 연구의 양적 및 질적 동향과 과제에 대하여 논의하였으며, 마지막으로 관련 연구 활성화를 위한 향후 방향 및 발전 과제에 대하여 제언하였다. There has been a rapid increase of interest in research on young children with autism spectrum disorders. This may be related to the increase in prevalence being reported globally as well as the emphasis on possibilities of early detection and needs of early supports. However, compared to the research being conducted abroad, domestic research is still at an early stage in terms of its quantitative and qualitative aspects. Therefore, this study was to investigate current trends of research regarding young children with autism spectrum disorders in Korea, to discuss challenges faced by the field, and to suggest future directions for active and practical research activities. For the purpose of this study, a total of 137 articles published during the decade from 2001 to 2010 were analyzed. The overall research trends were recognized and an additional analysis was done with 57 target articles conducted in order to verify functional relationship between interventions and research outcomes. Based on the findings of the study, implications and suggestions for the future directions of the related research were also discussed.

Diversifying software licensing models in markets with different customer influence in network effect

이소현,박건수 한국경영과학회 2023 한국경영과학회 학술대회논문집 Vol.2023 No.5

As software-as-a-service (SaaS) proves to create economy of scale compared to on-premise software, SaaS becomes a widely selected deployment type for software providers in various industries. However, in some markets where personal data security is a primary issue, there are institutes or customers that prefer on-premise deployment types to SaaS, fearing the outflow of data in virtual or external servers. In this case, software providers must choose whether to provide both deployments to increase the total customer base, or only serve SaaS to make efficiency in operational cost. To choose which level of on-premise deployment to offer to high-influence customers, software providers must take into account the network effect. In this thesis, we provide an optimal provision ratio for deploying two types of software considering the network effect by different influence levels of each customers. Our model applies the total network effect into the customer valuation to reflect increase in the total demand and revenue, also calculating larger operational costs to serve high-influence customers as consistent to reality. The computational result using real-world data from a medical software company, tells us that as the percentage of ‘only on-premise’ users increase, the optimal ratio of influential customers to provide on-premise versions decrease. This result is due to the increasing cost in time and effort needed to serve more onpremise customers with high influence effect.

Asian Women in Hollywood Action/Crime Films: The Variation and Perpetuation of Oriental Femininities

이소현 문학과영상학회 2014 문학과영상 Vol.15 No.4

This paper examines the representation of Asian women in U. S. action/crime movies from the late 1990s to the early 2000s. It focuses on the tradition of action/crime films in light of the cinematic portrayals of Asians and Asia, and explores how Asian women have been depicted in relation to their existing stereotypical images and the genre conventions. Closely looking at the representation of Asian women in Charlie’s Angels (2000), Tomorrow Never Dies (1997), Red Corner (1999), and The Art of War (2000), the paper reflects on the articulation of differences of race, gender, and ethnicity in consideration of the influences of Hong Kong action movies, the cinematic discourse of Oriental femininities, and the contextual specificities. Given the marginality of Asian women in the mainstream U. S. cinema, the increasing presentation of Asian women in mass-oriented action/crime films may offer an important site where Asian women are visible. The representations of Asian women in action/crime films can illustrate the ways in which the Western discourse of Oriental femininities is transformed, negotiated, or perpetuated, and allow for an understanding of how the Hollywood industry incorporates the trend of “Asiaphilia” in relation to global marketing strategies.

Association between Alcoholism Family History and Alcohol Screening Scores among Alcohol-dependent Patients

이소현,이병철,김지욱,이중서,최인근 대한정신약물학회 2013 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.11 No.2

Objective: Several tests can be used to screen for alcohol dependence (AD), a prevalent disease with a heterogeneous etiology. As some patients with AD have a strong familial tendency in this regard, a family history of alcohol use disorders can affect the outcomes of screening tests and diagnostic evaluations for AD. In this study, we evaluated associations between a family history of alcohol use disorders and evaluations using the Cut down, Annoyed, Guilty, Eye-opener (CAGE) test, Alcohol Use Disorder Identification Test (AUDIT), and Diagnostic and Statistical Manual of Mental Disorders-fourth edition (DSM-IV) diagnostic criteria among patients with AD. Methods: We recruited 487 male patients with AD from eight hospitals in Korea. Patients were evaluated using the CAGE, AUDIT,and DSM-IV diagnostic criteria. Patients with and without family histories were compared in terms of these assessment tools. Results: Drinking initiation, uncontrollable drinking, and problem drinking occurred earlier and CAGE “annoyed” scores were higher in patients with a family history. Alcohol problems before the age of 25 years, frequency of spontaneous or compulsive alcohol-seeking behavior, and frequencies of psychological dependence and guilt related to alcohol use were also higher. Conclusion: Earlier drinking problems, higher scores on specific items of the CAGE, and AUDIT, and meeting more diagnostic criteria indicate more dependent, harmful drinking by patients with AD who have a family history of this condition. Clinicians should consider patients’ family history of alcohol use disorders when screening for AD to identify the correct diagnosis and develop appropriate treatment plans for these patients.

Methyl Orange를 이용한 나일론 직물의 염색 및 산성용액 접촉에 따른 색 변화

Strong acids, such as hydrochloric acid and sulfuric acid, are colorless and are not easily detected when leaked. Halochromic dyes can be used for detecting strong acids because they show different colors when exposed to acid liquids. In this study, methyl orange was used as a pH-indicating dye in detecting acid liquids. Nylon 66 woven fabric was dyed with methyl orange, and the dyeing properties were determined, along with the pH-sensing property, colorfastness, and fixing agent effect. Methyl orange in an aqueous solution showed maximum absorption at 464 nm with orange color at a pH of 5−10, whereas the maximum absorption changed to 507 nm showing red color at a pH of 2. Nylon 66 dyed with methyl orange exhibited a good color yield (K/S), and the dyeing property was influenced by the pH and dye concentration. When the dyed sample was immersed in a solution with a pH range of 3.5−4.0, its original orange color was maintained. Then, the color turned to reddish-orange when immersed in a solution of 2.0-3.0 pH and red in a pH 1.5 solution. The acid-sensing property was retained after fixing agent treatment. The wash and water fastness of the dyed fabrics varied from poor to very poor, and the fastness of the staining was improved to a moderate level by fixing agent treatment. The lightfastness indicators before and after the application of fixing agent treatment were moderate and good, respectively.

연구 목적: 본 연구는 골형성단백질의 서방출을 위해 헤파린과 골형성단백질 (rhBMP-2)을 화학적으로 고정시킨 양극산화 티타늄 임플란트가 골 결손부에서 임플란트 주변의 수직적 골증대에 미치는 효과를 방사선학적으로 평가하고자 시행되었다. 연구 재료 및 방법: Pure-Titanium을 사용하여 길이 7.0 mm, 직경 3.5 mm의 실험용 임플란트 18개를 제작하였다. 모든 임플란트를 양극산화처리 하였고, 플랫폼 하방 2.5 mm에 식립 기준선을 표시하였다. rhBMP-2가 코팅되지 않은 임플란트 집단을 대조군으로, dip and dry 방법으로 rhBMP-2를 물리적 흡착시킨 집단을 BMP군, 3,4-dihydroxyphenylalanine(DOPA)-heparin을 이식하고 rhBMP-2를 화학적으로 고정시킨 집단을 Hep-BMP군으로 설정하였다. 각군별6개씩의 임플란트를 3마리의 비글견 양측 하악에 한쪽에 3개씩 총 18개를 치조정 상방으로 2.5 mm 노출시켜 식립하였다. 식립 직후와 4주, 8주에 식립부위의 방사선학적 검사가 시행되었고, 각 시기별, 각 군별 임플란트의 근원심 변연골의 수직적 재생량에 대한 평균값과 표준편차를 얻었다. Kruskal-Wallis test와 Mann-Whitney U test를 이용하여 4주, 8주에서 대조군과 실험군들의 차이를 비교 분석하고, 유의 수준5%에서 통계적으로 검정하였다. 결과:방사선학적 관찰 결과 임플란트 근원심 변연골 재생량(평균값 ${\pm}$ 표준편차)은 4주에 대조군은 $0.09{\pm}0.22mm$, BMP군은 $1.02{\pm}0.72mm$, Hep-BMP군은 $1.29{\pm}0.51mm$ 였으며, 8주에서는 각각 $0.11{\pm}1.26mm$, $1.11{\pm}0.58mm$, $1.59{\pm}0.79mm$였다. 두 실험군 모두 4주와 8주에서 대조군과 비교 시 유의한 수직적 골증대를 나타냈으나(P<.05), Hep-BMP군과BMP군의 비교에서는 유의한 변연골 재생량 차이를 보이지 않았다(P>.05). 결론: 골형성단백질을 물리적으로 흡착시키거나 서방출 위해 헤파린을 이용하여 화학적으로 고정시킨 양극산화 임플란트 표면은 모두 골 결손부에서 임플란트 주변골의 수직적 증대에 효과적이었다. 그러나 방사선학적 관찰의 한계 내에서 골형성단백질의 이 두가지 적용방법간에는 수직적 골증대량에 유의한 차이가 없었다. Purpose: The aim of this study was to evaluate the effect of immobilization of the recombinant human bone morphogenetic protein 2 (rhBMP-2) on anodized titaum implants coated with heparin to enhance the vertical alveolar ridge augmentation in the supraalveolar peri-implant defect region. Materials and methods: 18 pure titanium implants (7.0 mm in length, 3.5 mm in diameter) were manufactured for this study. All implants were anodized and designed insertion reference line marked with laser at the apical 2.5 mm from the fixture platform. Implantation of 6 noncoated anodized implants (Control group), 6 anodized implants physically adsorbed with rhBMP-2 by dip and dry method (BMP group) and 6 anodized implants chemically immobilized 3,4-dihydroxyphenylalanine (DOPA)-heparin/ rhBMP-2 (Hep-BMP group) was performed in the both mandibular of three male adult beagle dogs using split-mouth design. Radiologic examinations were performed immediately after implant placement and 4 and 8 weeks after implant placement. The amount of mesio-distal bone augmentation was evaluated by measuring the vertical distance from the platform to the marginal bone. Statistical analysis was performed using one-way analysis of variance (SPSS version 18.0) and multiple comparison analysis of The Kruskal-Wallis test and the Mann-Whitney U test. Statistical significance was established at the 5% significant level. Results: At the 4 weeks vertical alveolar ridge augmentation of Control group, BMP group and Hep-BMP group is $0.09{\pm}0.22mm$, $1.02{\pm}0.72mm$, and $1.29{\pm}0.51mm$, At the 8 weeks $0.11{\pm}1.26mm$, $1.11{\pm}0.58mm$, $1.59{\pm}0.79mm$ according to radiographic observations. The two experimental groups showed a significantly increasing in vertical bone height compared with the control group (P<.05). However, there is no significant difference between the BMP group and Hep-BMP group (P>.05). Conclusion: The rhBMP-2 coated implants were enhanced the vertical bone growth in the supraalveolar peri-implant defect area. However, there is no significant difference between chemically and physically coating method.
