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.

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.

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.

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.
