The detailed studies regarding to the front and rear panel geometries of plasma display were needed to improve the luminance and efficiency. In plasma displays, 3-dimensional optical code can be used to analyze the variation of geometries and the changing of optical properties. The visible light distributions and illuminance were simulated depending on bus electrode position, ITO geometries, and alteration of dielectric layer's properties. This paper is concerned with development of a cell having high luminance and high efficiency for optical simulation. And the result of values could be expected to the application of real POP cell.

Microbial Treatment of Azo Dyes Using Biogenic Bimetallic Iron–Molybdenum Nanoparticles

정선욱,Yang Jung Eun,최용준 한국화학공학회 2024 Korean Journal of Chemical Engineering Vol.41 No.7

Azo compounds have long posed a serious threat to publish health and the aquatic environment. Therefore, the adverse eff ects of azo compounds on public health have inspired the need to develop effi cient and reliable treatment methods. Although various physicochemical treatment methods have been developed, bio-inspired environmentally friendly treatment method have not yet been reported. Here, we report the development of a novel azo compound treatment method using biogenic nanoparticles immobilized microorganism. Firstly, biogenic bimetallic iron–molybdenum nanoparticles immobilized Deinococcus radiodurans R1 (DR-FeMoNPs) were constructed. Next, physicochemical properties of FeMoNPs including specifi c surface area (53.627 m 2 g −1 ), pore volume (0.3561 cm 3 g −1 ), and average pore diameter (19.205 nm) were thoroughly addressed. The resulting FeMoNPs-immobilized D. radiodurans R1 exhibited an 87.2% removal effi ciency for Congo Red, with a maximum capacity of 172.4 mg/g. Additionally, the rapid degradation of residual H 2 O 2 , triggering Fenton-like reaction via biological scavenging mechanism, was confi rmed. DR-FeMoNPs also demonstrated highly effi cient removal of other types of azo compounds, such as Acid Orange 7 (99.4%) and Evans Blue (81.1%).

정선욱(SunWook Jung),손주영(JuYoung Son),김은정(EunJung Kim) 한국콘텐츠학회 2016 한국콘텐츠학회논문지 Vol.16 No.10

본 연구는 기업이 참여하는 창업지원사업의 성과를 저소득층 지원대상자의 관점에서 평가한 것이다. 본 연구는 기업이 참여하는 창업지원사업 가운데 대표적인 사례로 볼 수 있는 현대자동차그룹의 기프트카 캠페인을 분석하였다. 이 창업지원사업의 성과를 질적 평가 방법으로 분석한 결과, 지원 대상자들은 ‘책임감을 갖고 열심히 일함’, ‘미래가 있는 삶이 현실로!’, ‘‘나’와 ‘나’를 둘러싼 관계의 변화’ 등의 경제적·비경제적 성과를 경험하는 것으로 나타났다. 이러한 성과의 본질은 ‘‘다름’의 경험’, ‘저소득층의 삶에 숨결과 희망을 투입’하는 것으로 정리될 수 있다. 본 연구를 통해 밝혀진 성과는 기업 창업지원사업의 가치와 의미를 재확인시켰고, 빈곤과 자립이라는 사회문제 해결에서 기업이 담당해야 할 중요한 몫이 갖는 중요성 또한 입증하였다. This research is about brief accomplishment analysis of Low-Income Class Business Incubator Project, based on applicants’ perspective who has been supported by this project, which is funded by the enterprise. As a result of quality focused evaluation method, it shows that Low-Income Class Business Incubator Project’s applicants experience both economic and non-economic accomplishments such as “work with responsibility,” “better future in reality,” “Self and change of relationships around self”. It concludes that “experience of difference” or “providing hope for Low-income class” brought positive effects on applicants who participated in this projects. The study revealed the virtue of this Low-Income Class Business Incubator Project and reassured its message: the importance of major corporate’ responsibility in solving social issues, especially in poverty and its independence.

본 연구의 목적은 대학에 진학한 시설보호 청년의 결혼 태도와 결혼 태도 영향요인을 발견하는 것이다. 대학에 진학한 시설보호 청년은 발달단계상 성인이행기에 있으며, 이 발달단계에서 중요한 발달과업 중의 하나는 친밀하고 낭만적인 관계 맺기, 결혼의 선택이다. 본 연구는 이들의 결혼 이슈를 결혼 태도를 중심으로 살펴보았다. 전국의 양육시설과 자립생활관의 협조를 받아 총214명의 대학 진학 시설보호 청년에 대한 설문조사를 시행하였고 연구 결과, 이들의 결혼에 대한 태도는 대체로 호의적인 것으로 나타났다. 이들은 결혼을 외로움을 해소시켜주는 바람직하고 좋은 것으로 인식하는 경향이 있었다. 결혼 태도에 영향을 미치는 요인은 성별, 경제 수준, 자아정체감으로 나타났다. 자아정체감 하위3요소 가운데 자기 수용성, 즉 자신감과 자신을 신뢰하는 정도가 결혼 태도에 영향을 미쳤다. 이러한 연구 결과를 바탕으로 시설보호 청년의 자립 과정에서 결혼 이슈를 고려하는 것의 필요성과 의의, 결혼이 실질적인 자립 지원책으로 기능하기 위해 고려되어야 할 사항 등을 제시하였다. The purpose of this study is to find influencing factors on attitude toward marriage of undergraduate with institutional care background. Intimate romantic relationship is one of developmental tasks of emerging adulthood. And attitude towards marriage is connected with intimate, romantic relationship. This study has focus on attitude towards marriage out of marriage issues. The method of this study is the survey on 214 undergraduates who have lived in institution for children over two years. The results of the findings are as follows. First, they are favorably inclined towards marriage. Second, gender, financial conditions, ego-identity exercise a significant effect on attitude towards marriage. Subcategory of ego-identity that affects attitude towards marriage the most is self-receptiveness. Implication and limitation of this study are discussed finally.

The estimated incidence of conjoined twins is one in 50,000 births, however, over 60% are stillborn, making the observed incidence around one per 200,000 live-births. Thoracopagus is the most common variety of conjoined twins accompanying with congenital heart disease 75%, fusion of alimentary tracts 50%, single external biliary tract 25%. Approximately 90% of thoracopagus conjoined twins are not candidates for surgical separation due to the high degree of cardiac union and the complexity of cardiovascular anomalies. With improvement in prenatal diagnosis and routine ultrasound monitoring of pregnancies, these cases are more commonly being diagnosed prenatally. Accurate diagnosis of the shared anatomy and associated malformations is crucial for counseling of the affected families regarding outcome as well as planning potential postnatal surgical separation. We experienced a case of thoracopagus with single conjoined heart that was diagnosed by ultrasonography at 15 weeks of gestation in 33 years old woman. So we present this case with a brief review of literatures.

The purpose of this study is to find out what to consider for future changes in child residential institutions and further improvement of the child out-of-home care system through an understanding of the < Small-scale Home-style Institution Pilot Project > in a child residential institution operated by a social welfare foundation, conducted at one district office in Seoul. This study applied an essential case study method to collect, analyze, and write data. This study argues that new changes require an innovative promotion system, that a strategy that avoids the challenges that come with new changes should not be chosen, that an institutional environment where new attempts are possible must be established to prevent actions to return to past practices, and that future pilot project should be systematically prepared and operated. In addition, it was emphasized again that a fundamental paradigm shift centered on children is required when setting the direction of new change in the out-of-home care system, and that child-centeredness is to focus on what children want and feel.

The purpose of this study is to examine how researchers understand and utilize qualitative evaluation methods of social welfare program. To achieve this purpose, this study analyzed 96 qualitative program evaluation studies in social welfare literature from 2000 to 2012 indexed by RISS(Research Information Shearing Service: academic literature searching engine in Republic of Korea). In terms of qualitative analysis, several themes were reviewed for these selected studies: what they called their research methods instead of the qualitative evaluation methods, why they used the different evaluating methods, not just quantitative ways, what were the objects of the studies, and how they built and performed their evaluating plans including data collection, data analysis and writing. The results are as follows. The researchers hesitated using qualitative evaluation term, officially and directly. In spite of that, they used the qualitative evaluation methods because of their unique characteristics, complementary effect, and so on. The objects of qualitative evaluations were focused on participants of social welfare program. The procedures according to evaluation plans were insufficiently described. Based on these analyses, it is suggested as the ways of improving quality of social welfare program evaluation studies using qualitative methods, to revise educational curriculums for developing qualitative evaluator`s ability and change quantity-oriented evaluating system.
