Back ground & Objectives : Bilateral sudden sensorineural hearing loss(SSNHL) is very rare disease. This is the first case report in the oriental medical literature. This study describes a case of bilateral SSNHL with incomplete recovery. Methods : We treated 1 patient who had SSNHL sequentially in both ears. He received oriental and western medical treatments for more than 2 weeks and measured the hearing recovery. For diagnosis on this case, pure tone audiometry was used. The degree of improvement was evaluated by Siegel's Criteria. Results & Conclusions : This patient discharged without hearing improvement. For bilateral SSNHL patients, the result of treatment is important for their qualities of life. But the recovery rate of hearing in bilateral SSNHL is lower than unilateral SSNHL. The oriental medical therapy had some theraputic effects on SSNHL and the theraputic effects on bilateral SSNHL requires further study.

In preparative anti-corrosive coating experiments, polyaniline was obtained by reacting an oxidizing agent with the monomer aniline. Further, the primer coating was prepared using a variety of widely-used materials such as urethane resin. For the top coating, epoxy resin and acrylic urethane resin were used. Characteristics of the coatings were assessed according to KS and ASTM specifications, and the structure of the polyaniline was characterized using FT-IR and TGA. For analysis of anti-corrosive properties in salt-spray experiments, measurements of the oxidation state of iron and surface atomic analysis were conducted using XPS and SEM-EDX. Unlike general anti-corrosive coatings which exhibit anti-corrosive effects only as a primer coating, the anti-corrosive coatings using polyaniline as the anti-corrosive pigment showed a marked synergistic effect with the top coatings. In other words, the top coatings not only produce a fine view effect, but also increase, through interaction with the primer coatings, the resistance to diffusion of corrosive factors from the external environment. It was also found that, unlike the heavy metal oxide-forming layer of the passive barrier alone, the polyaniline anti-corrosive pigment oxidized iron at the interface with the iron substrate to form a passive barrier in the oxidic layer, and itself formed a potential barrier layer with anti-corrosive factors from the external environment. Although the passive layer was damaged, the damaged area did not become completely oxidized iron; on the contrary, it showed a tendency to reduction. This can be interpreted such that a passive layer is formed again on the damaged area, and that at the same time there is a tendency to self-healing.

The National Cyber Capability Assessment(NCCA) could be used as meaningful information for improving national cyber security policy because it provides information on the elements necessary for strengthening national cyber capabilities and the level of each country. However, there were few studies on improving cyber capabilities using the NCCA result in Korea. Therefore, we analyzed the result of National Cyber Power Index(NCPI) conducted by Belfer Center of Harvard Univ. by applying modified-IPA method to derive cybersecurity policy agendas for Korea. As a result, the need to set agendas on surveillance and offensive cyber capability and improve the effectiveness of policy implementation for intelligence and defense was drawn. Moreover, we suggested need for in-depth study of each policy agenda deduced from preceding research data as a future tasks. And it is expected to increase practical use of NCCA for domestic policy analysis by developing and using our own NCCA model which considered analysis framework proposed in this study. 국가 사이버 역량평가는 국가 차원의 사이버역량 강화를 위해 필요한 요소와 그에 대한 국가별 수준에 대한 정보를 제공하기 때문에 국가 사이버안보 정책 개선을 위한 기초자료로 활용할 수 있다. 그러나 그간 우리나라를 평가대상국으로 포함하여 평가를 진행한 다양한 평가결과로부터 국내 사이버역량 개선을 위한 정책적 분석은 다소 부족하였다. 이에 본 논문에서는 미국 하버드 대학의 벨퍼센터에서 수행한 국가 사이버 추진력 지수(NCPI)의 평가결과에 대해 IPA(Importance-Performance Analysis) 기법을 변형·적용해봄으로써 우리나라 사이버안보 정책 개선 방안을 도출하고자 하였다. 분석 결과, 우리나라는 공격과 감시 목적의 사이버 기능 활용에 관한 정책 의제 형성이 필요하고, 인텔리전스와 방어에 관한 정책의 실효성을 향상하기 위한 노력이 필요하다는 결론을 얻을 수 있었다. 또한, 관련 정책 의제를 다루는 국내외 연구사례를 살펴봄으로써 정책개선 방향을 제시하며, 각 정책개선 방향에 관한 심층 연구를 추진할 것을 향후 과제로 제안하였다. 나아가 국가 사이버 역량평가 모델의 정책 분석적 활용을 향상하기 위해서는 국내 실정을 반영하는 자체 모델 개발·활용이 필요하며, 이때 본 연구에서 제안한 평가결과 분석 방안을 활용할 수 있을 것으로 기대한다.

송민경,홍승욱,Song, Min-Kyung,Hong, Seung-Ug 대한한방안이비인후피부과학회 2013 한방안이비인후피부과학회지 Vol.26 No.1

Objectives : We aimed to determine therapeutic effects of probiotics-fermented Magnolia denudata(MD) in the allergic rhinitis model mice. Methods : Polyphenol production, DPPH radical scavenging activity and NO inhibition of fermented MD by different bacterial strains were evaluated to select the one that is most suitable for fermentation. Thirty C57BL/6 mice were divided randomly into 5 groups as follows: normal group, ovalbumin(OVA)-treated plus water fed(CON group), OVA-treated plus unfermented MD fed(UMD group), OVA-treated plus fermented autoclaved MD fed(A-FMD group) and OVA-treated plus fermented unautoclaved MD fed(FMD group). After 9 weeks, we observed changes in the blood cell count, OVA-specific IgE level, nasal rubbing, nasal mucosal tissue and body weight. Results : Extract of MD fermented by Bifidobacterium breve(BB) for 48 hours showed the highest anti-oxidant activity and anti-inflammatory activity out of all the other bacterial strains. The number of eosinophil count in A-FMD, FMD group and platelet count in FMD group showed statistically significant decrease(p<0.05). OVA-specific IgE level decreased in all 3 experimental groups, significantly in UMD and A-FMD group. Nasal symptoms were attenuated in all 3 experimental groups, statistically significant in A-FMD and FMD group (p<0.05). Histologically, infiltration of eosinophils into the nasal mucosa decreased in all 3 experimental groups, especially marked decrease in FMD group. Conclusions : According to the above results, it is considered that probiotics-fermented Magnolia denudata has inhibitory effects on the allergic rhinitis animal models.

송민경,조용주,Song, Min-Kyoung,Cho, Yong-Joo 한국정보통신학회 2012 한국정보통신학회논문지 Vol.16 No.1

본 논문은 컴퓨터과학 교육에서 협동학습과 개별학습이 학습자에게 어떠한 효과가 있는 지에 대해 연구하였다. 협동학습은 우리나라 IT 기업들에서는 프로젝트 방식의 업무 처리 비중이 높아지고 있기 때문에 컴퓨터 과학 분야의 학습자들에게 협동학습의 훈련은 매우 중요시되고 있다. 본 연구는 개별학습과 협동학습에 대해 학습자들이 어떠한 견해를 가지고 있는지를 연구하고 학습 유형 별 실험을 통해 어떠한 학습의 차이를 가져오는지 설문과 실험을 통해 분석하였다. 이 연구는 서울 소재의 한 대학교에 컴퓨터 관련학과 전공과목을 수강하는 학생들을 학습 방법에 기초해서 두 집단으로 나누어 실험하였고 그 결과를 비교 분석하여 효과 및 문제점을 논의한다. This paper investigated the effects of cooperative learning and individual learning in computer science education. Most works and projects are accomplished in groups in most IT companies in Korea. Thus, cooperative learning is one of the most important aspects that must be learned in schools. This research studies how students think of individual and cooperative learning. It also researches and analyzes how different learning methods would affect the learning effects with surveys and experiments, which were conducted during two consecutive semesters with students in a department of a computer related major at a university in Seoul. This research compares and analyzes the results after dividing the students in two groups based on the different learning methods.

화염상모반을 동반한 와이번 메이슨 증후군 환자 1예의 임상양상과 빛간섭단층촬영 소견

송민경(Min Kyung Song),김대희(Dae Hee Kim),안효숙(Hyo Sook Ahn) 대한안과학회 2016 대한안과학회지 Vol.57 No.8

목적: 대표적이고 드문 모반증의 하나인 와이번 메이슨 증후군(Wyburn-Mason Syndrome) 환자 1예의 임상양상과 빛간섭단층촬영 소견을 보고하고자 한다. 증례요약: 5세 남아가 우안 시력저하를 주소로 내원하였다. 내원 시 우측 이마와 윗눈꺼풀, 뺨 주위에 화염상모반을 보이고 있었다. 우안의 최대교정시력은 안전수동이었고, 상대구심동공운동장애가 관찰되었다. 안저검사에서 구불거림이 심하고 동정맥의 구분이 명확하지 않은 혈관이 후극부를 덮고 있었으며 빛간섭단층촬영에서 내경계막을 넘지 않는 혈관이 망막 내에서 커져 있는 소견이 관찰되었다. 뇌혈관조영술에서 우측 내경동맥으로부터 우측 안동맥이 직접 연결된 소견이 관찰되었고 우측 비강 내의 벌집동맥까지 혈관이 커진 소견이 관찰되었다. 결론: 와이번 메이슨 증후군은 흔하지 않은 모반증으로서 특징적인 망막 소견을 보이며, 적절한 진단과 치료가 이루어지지 않는 경우 심각한 합병증을 초래할 수 있는 질환이다. 안면부에 화염상모반이 동반되는 경우 이 질환에 대한 감별이 필요하다. 빛간섭단층촬영은 이 질환에서 망막 혈관기형에 대한 구조적 이해에 도움을 줄 수 있는 검사로 사료된다. Purpose: To describe a case of Wyburn-Mason Syndrome, which is a rare phakomatosis, and its associated optical coherence tomography findings. Case summary: A 5-year-old boy was referred to our clinic for decreased vision in his right eye. He had nevus flammeus on his right forehead, upper eyelid, and cheek. His best corrected visual acuity was hand motion in the right eye, in which a relative afferent pupillary defect was noted. Fundus examination of the right eye showed marked dilation and tortuosity of retinal vessels, which could not be discriminated between arteries and veins on the posterior pole. Optical coherence tomography showed multiple large intraretinal vessels without involvement of the internal limiting membrane. Cerebral angiography revealed arteriovenous malformations (AVMs) and feeder vessels from the internal carotid artery to the ophthalmic artery, extending to the ethmoidal artery in the nasal cavity. Conclusions: Wyburn-Mason syndrome is a rare phakomatoses and shows unique retinal AVM. Misdiagnosis or undertreatment of Wyburn-Mason syndrome can lead to serious complications. Patients with facial nevus flammeus should undergo thorough ocular examinations to rule out this disorder. Optical coherence tomography is a useful method for understanding structural features of retinal vascular malformations in Wyburn-Mason syndrome.

6분과 : 신규조림,재조림 활동의 산림탄소흡수원 지수 개발

송민경 ( Min Kyung Song ),배재수 ( Jae Soo Bae ),설미현 ( Mi Hyun Seol ) 한국임학회 2014 한국산림과학회지 Vol.103 No.1

2013년 3월에 발효된 ‘탄소흡수원 유지 및 증진에 관한 법률’ 제26조에서 규정한 신규조림·재조림 활동의산림탄소흡수원 지수를 개발하였다. 특정 시점에서의 개별 산림탄소상쇄사업의 실적을 평가하여 상호 비교하고자 하는 법적인 목적에 따라 점수화 방법을 사용하여 산림탄소흡수원 지수값을 산출하였다. 탄소흡수원법을 바탕으로 하여 ‘탄소’(온실가스 감축), ‘인간’(사회경제적 영향), ‘자연’(환경적 영향)의 3대 기준을 설정하였다. 각 기준에 속하는 9개의 지표를 top-down 방식으로 선정하였고, 전문가 온라인 설문조사를 통하여 기준과 지표의 정합성을 검토하고 가중치를 도출하였다. 사회공헌형을 대상으로 하고 있는 국내 산림탄소상쇄사업의 특성을 반영하여, 기준과 지표 간 가중치의 간격을 최소화하는 점수가중치 부여 방식을 적용하였다. 국내에서 시행중인 5개 산림탄소상쇄사업을 대상으로 개발된 지수를 시범적으로 적용하여 평가한 결과, 상대적으로 가중치가 낮은 ‘인간’ 및 ‘자연’ 기준이 실제적으로 부정적인 사회경제적·환경적 영향을 저감하도록 유인하는 역할을 할 수 있음을 확인했다. 산림탄소흡수원 지수의 평가 결과를 바탕으로 우수 사업자에 대한 포상이 가능하며, 이는 국내 산림탄소상쇄사업의 참여 활성화를 위한 유인수단이 될 것이다. We have developed the Forest Carbon Sink Index on afforestation and reforestation activities, a regulation stated in article 26 of the ‘Law on the maintenance and enhancement of carbon sink (Carbon Sink Law)’, which took effect on March, 2013. According to the legal purpose to evaluate the performance of individual forest carbon offset projects and to compare each other at a certain point, values of the forest carbon sink index were calculated by the scoring method. Three criteria were established based on the Carbon Sink Law: ‘Carbon’ (real greenhouse gasreduction), ‘Human’ (socio-economic effect) and ‘Nature’ (environmental effect). Continuously, 9 indicators from the three criteria were selected by top-down approach; the adequacy of each criteria and indicators were reviewed through on-line Delphi survey; and finally weighted value of each criteria and indicators were assigned. To reflect the characteristics of the domestic forest carbon offset projects, which focus on corporate social responsibility-typed projects, we applied the score weighting method to minimize gaps among criteria and ones among indicators. After applying our newly developed forest carbon sink index to five domestic forest carbon offset projects, we could confirm that the criteria of ‘Human’ and ‘Nature’, which criteria are in relatively low weight, can play a role as an actual incentive to reduce negative socio-economic and environmental impacts. Based on performance evaluation of the five forest carbon offset project by the forest carbon sink index, the best or good performance project developers could be rewarded, and further the performance evaluation would work as an incentive to stimulate the involvement of domestic project developers in the field of forest carbon offset project.

온라인에서의 레스토랑 구전정보 작성자와 구전평가 방향에 따른 레스토랑 방문의도와 정보 신뢰도 차이 연구

송민경(Min Kyung Song),윤혜현(Hye Hyun Yoon) 한국조리학회 2013 한국조리학회지 Vol.19 No.2

The arrival and expansion of the Internet has extended consumers` options and has provided consumers` opportunities to offer their own consumption. Through a laboratory experiment, we investigated questions: 1) do consumers trust the accuracy of reviews posted by anonymous reviewers or experts and 2) do readers trust negative and positive reviews equally? The messages were created as a form of 4 scenarios for this study. The statistical analysis was conducted using SPSS Win(v.16.0) for descriptive analysis, and t-test. Our results from a 2(positive reviews vs. negative reviews)*2(consumer vs. expert) experiment design showed that there was a significant difference between consumers` review and experts` one in restaurant visit intention(p<.001) and information credibility(p<.001). Also, between positive review and negative one, significant difference was found in restaurant visit intention(p<.001) and information credibility(p<.01). Other results, limitations and future research directions were also discussed.

미국의 학대피해 위탁아동의 친권상실 결정요인에 관한 연구

송민경(Min Kyoung Song) 한국아동복지학회 2006 한국아동복지학 Vol.- No.22

본 연구는 미국의 학대피해 위탁아동을 중심으로 위탁보호기간 소요에 따른 친권상설 위험율의 추이와 친권상설에 관한 요언을 분석하였다. 특히, 1997년 개정된 아동 복지법(the Adoption and Families Safety Act, 이후 ASFA) 이후 최초 위탁보호된 아동의 친권상실 위험율의 추이를 살펴본 결과 1개월에서 6개월 사이에는 친권상실이 매우 미비하게 발생했으나, 이후 계속 꾸준히 증가하다가 19개월에서 24개월 사이에 가장 빈번히 발생한 것으로 나타났다. 학대피해 아동이 최초 위탁보호 당시 연령이 어릴수록, 흑인아동일 경우, 부모가 약물중독이나 유기로 인해 위탁보호된 경우, 그리고 선입양가족이나 일반위탁가족에 보호된 경우에 비교적 높은 친권상실 가능성을 나타내고 있었다. 이러한 피학대아동에 대한 공적 친권개입과 친권상실에 대한 분석 결과를 토대로 공적 친권개입과 친권상실에 대한 정책적 함의와 제도적 제언을 제시하였다. This study examines the timing and the risk factors associated with the termination of parental rights who first enter foster care due to child abuse and neglect. For the purpose of the study, the sample was drawn from foster care files of Adoption and Foster Care Analysis and Reporting System (AFCARS) in 32 states between October 1998 (FY1999) and September 2002 (FY2002). The timing from first entry into foster care to TPR was examined by plotting the Kaplan-Meier survivor / and hazard functions. Survey logistic regression analysis was used to identify risk factors for TPR of foster children. The hazard of TPR was very low after first entering foster care, but in­creased rapidly starting at 10 months and then declined after 32 months in care. Factors associated with a higher likelihood of TPR include younger age, Black / African Ame­rican, parental substance abuse and parental abandonment, and pre-adoptive family homes. The findings of this study suggest that more specific targeted strategies and perma­nency planning via TPR should be developed for racial minority children and older children. Also, this study recommends more intensive family reunification efforts for the cases that involve parental substance abuse and specialized care for drug treatment in order to avoid TPR and promote permanency in child welfare system.
