Whether the logic of the Dependency Theory is in order or not, it, today,is supported many scholars and becoming a main argument of world politics among them. This theory functions as a positive factor and negative ane as well in the development of the Developing Coutries. The majority of the less developed countries pursue excessive selfreliance strategy to free themselves from the state of dependency, attributing the cause of their less-development to the diffusion theory of the Developed Countries. This study examined the relevance of the Dependency Theory on the critical basis. For this porpose, this study explored the concept and condition of dependency, the structure and structural property of dependency, and moderate self-reliance strategy as an alternative to the Dependency Theory.
Antimicrobial Effect of Nisin against Bacillus cereus in Beef Jerky during Storage
Lee, Na-Kyoung,Kim, Hyoun Wook,Lee, Joo Yeon,Ahn, Dong Uk,Kim, Cheon-Jei,Paik, Hyun-Dong Korean Society for Food Science of Animal Resource 2015 한국축산식품학회지 Vol.35 No.2
The microbial distribution of raw materials and beef jerky, and the effect of nisin on the growth of Bacillus cereus inoculated in beef jerky during storage, were studied. Five strains of pathogenic B. cereus were detected in beef jerky, and identified with 99.8% agreement using API CHB 50 kit. To evaluate the effect of nisin, beef jerky was inoculated with approximately 3 Log CFU/g of B. cereus mixed culture and nisin (100 IU/g and 500 IU/g). During the storage of beef jerky without nisin, the number of mesophilic bacteria and B. cereus increased unlikely for beef jerky with nisin. B. cereus started to grow after 3 d in 100 IU nisin/g treatment, and after 21 d in 500 IU nisin/g treatment. The results suggest that nisin could be an effective approach to extend the shelf-life, and improve the microbial safety of beef jerky, during storage.

We have fabricated SiO$_x$ nanowires on a large scale through a Pt-catalyzed process. The scanning electron microscopy (SEM) investigation revealed that the nanowires had diameters in the range of 30 $\sim$ 130 nm. X-ray diffraction (XRD), selected area electron diffraction (SAED), and energy-dispersive X-ray (EDX) analyses indicated that the nanowires were amorphous and consisted only of Si and O elements. The growth of the SiO$_x$ nanowires was most likely controlled by the base-growth mechanism with the assistance of the underlying Pt layer. The room-temperature PL spectrum measurement showed a broad emission band, peaking around 3.0 eV. This simple heating method, with the effectiveness of the Pt catalyst, can be applied to a wide range of substrate materials, which may contribute to producing various useful nanostructures.

The Bovine Corneal Opacity and Permeability (BCOP) assay have been proposed as reliable alternatives to the Draize test. Wider use of the method requires extensive international harmonization study for the validation of the BCOP assay as alternatives. The aim of this work is to establish the BCOP assay in Korea for the international harmonization. In this study, six chemicals and three cosmetics were selected for the test. The eye irritation of the chemicals has already evaluated by the ECVAM(European Centre for the Validation of Alternative Methods). We evaluate the eye irritation of them by the only bovine corneal opacity in the BCOP assay. The Draize test was also preformed for comparative purpose in three chemicals and three cosmetics. For opacity alone, values obtained for three chemicals showed a correlation of r=0.994 (p=0.001) with our Draize score. A correlation coefficient between our Draize score and the ECVAM`s Draize score was 0.982 (p=0.003). The bovine corneal opacity values of additional three chemicals showed a correlation of r=0.968 (p<0.001) with ECVAM`s Draize score. All of three cosmetics were evaluated as non-irritants by the bovine corneal opacity values and our Draize score. These results indicate the international harmonization of the BCOP assay is possible. In further study, the international harmonization study has to be organized with more chemicals and products in more countries.

The necessity of using animals to test whether new chemicals and products are eye irritants has been questioned over the last 20 years. During this process, numerous non-animal methods have been proposed as reliable alternatives to the Draize test. The neutral red uptake assay is the in vitro method to test the eye irritation of chemicals and products. We need to validate the neutral red uptake assay as alternatives for the international harmonization. Therefore, we studied for the establishment of the neutral red uptake assay in Korea. In this study, we evaluated the eye irritation of five chemicals and three cosmetics by the Draize test and the neutral red uptake assay. The results of the neutral red uptake assay showed a correlation of r=−0.893(p=0.107) with our Draize score in two chemicals. And the results of the neutral red uptake assay showed correlation of r=0.892(p=0.017) with the Draize score obtained from the ECVAM (European Centre for the Validation of Alternative Methods) in additional three chemicals. All of three cosmetics were evaluated as non-irritants by our Draize test and the neutral red uptake assay. As a result, the neutral red uptake assay was established in Korea. For the international harmonization, the validation study has to be performed with more chemicals and products in more countries.

집단지성과 전문가시스템을 이용한 전문지식관리를 위한 소셜네트워크 서비스의 설계
이경현(Lee Kyoung-Hyoun),김화종(Kim, Hwa-long) 한국IT서비스학회 2010 한국IT서비스학회 학술대회 논문집 Vol.2010 No.1
최근 몇 년 동안 웹 기반의 서비스는 웹 2.0이라는 단어로 설명되면서 집단지성, 소설네트워크서비스 등 다양한 형태로 발전되어 왔다 특히 소셜네트워크서비스는 모바일 환경의 발전과 함께 수년간 계속 발전할 것으로 예상된다. 그리고 집단지성의 경우 이제는 웹기반 서비스에서 고객의 요구를 판별하고, 새로운 지식을 작성하는 방법으로 많이 활용되고 있다. 본 논문에서는 인공지능의 한 방법인 전문가시스템(Expert System)과 집단지성의 기술을 활용하여 전문지식을 관리하는 소설네트워크서비스의 설계 및 구현의 과정을 설명하고자 한다.
