배경 및 목적: 본 연구는 전자구개도를 사용하여 한국어의 치경마찰음인 /ㅅ/와 /ㅆ/를 조음운동적 측면에서 비교 분석해보고, 치경마찰음 조음 시 나타나는 혀-구개 접촉에 관한 정보를 제공하기 위한 목적으로 시행되었다. 방법: 한국어가 모국어이며 발음에 문제가 없는 정상 성인 5명이 전자구개도를 착용하여 치경마찰음을 분절음 차원에서뿐 아니라 단어 내 위치 및 모음문맥을 달리하여 녹음한 후 팰라토그램을 분석하였다. 결과: 그 결과, /ㅅ/와 /ㅆ/는 협착의 너비와 혀-구개 최대접촉구간에서 유의한 차이를 보였다. /ㅆ/에서 협착의 너비가 더 좁고 전체 혀-구개 접촉구간은 더 넓게 나타났다. 단어 내 위치에 따른 차이는 유의하지 않았지만, 고모음인 /ㅣ/ 문맥에서는 저모음인 /ㅏ/에 비해 협착의 위치가 후방화되었으며, 지속시간도 가장 긴 것으로 나타났다. 또한 혀-구개 접촉 구간도 가장 넓게 나타났다. 논의 및 결론: 본 연구는 전자구개도를 사용하여 한국어 치경마찰음의 혀와 구개 접촉에 관한 정보를 제공했다는 점에서 그 의의를 갖는다. 또한 본 연구의 결과는 한국형 전자구개도의 개발의 기초자료로써 그 의미가 있다. Objectives: The present study is aimed an electropalatographic investigation of Korean fricatives /s/ and /s*/. All data from this study is based on the production of 5- adult speakers who speak Korean as their first language. Methods: Electropalatography (EPG) is an instrumental technique for showing tongue and palate contact during speech. The participants recorded /s/ and /s*/ in CV (/si/, /sɑ/, /su/, /s*i/, /s*ɑ/, /s*u/) and VCV (/ɑsi/, /ɑsɑ/, /ɑsu/, /ɑs*i/, /ɑs*ɑ/, /ɑs*u/) context using EPG and then, four variables were analyzed: row of medial groove (RMG), medial groove width (MGW), medial groove length (MGL), and maximum contact frame (MCF). Results: There was significantly greater medial groove width and maximum contact frame for / s*/ compared to /s/. The difference between /si/ and /sɑ/ was also found in the row of medial groove, medial groove width and maximum contact frame. /si/ was produced further back, and had a longer medial groove length. Also, it showed more total tongue-palate contact than /sa/. Conclusion: A various range of palatal contact patterns were found between typical adults for perceptually normal /s/ and /s*/. The results provided the information about tongue–palate pattern of Korean fricatives /s/ and /s*/. These findings would be utilized to build the basic data and useful information for Korean EPG system.

These studies were carried out to develop the low salt-fermented sea foods from ascidian. In present papers, we examined optimum processing conditions and quality improvement of the low salt-fermented ascidian. The optimum processing conditions of low salt-fermented ascidian was as followed. After deshelling and slicing a ascidian muscle in 5 mm width, and dipping in a 10% salt and 1% sodium erythorbate solution for 20 min. We dewatered it, and dipped it in 0.1% sodium bisulfite solution for 1 min, then added an anchovy sauce and rice gruel(1:1) mixture and finally fermented it at 5℃ for 15 days. The moisture and salinity contents of the low salt-fermented ascidian were 75.0~75.4% and 8.0 ~8.5%, respectively. During fermention at 5℃ for 20 days, amino-N contents of the low salt-fermented ascidian increased, and texture were softened gradually. The viable cell counts were 4.2~4.5×10^(4) CFU/g, and tended to decrease in the first stage during fermentation. The ratio of saturated fatty acids tended to increase in the early stage of fermentation, while that of polyunsaturated fatty acids decreased slightly during fermentation. In the results of chemical experiments and sensory evaluation, dipping treatment in 1% sodium erythorbate solution and 0.1% sodium bisulfite solution showed a good color and prevention of browning in the low salt-fermented ascidian, and also adding anchovy sauce and rice gruel mixture improved the taste of it.

Properties analyses and treatment characteristics of waste slurry discharged in the wetted flue gas desulfurization process using Mg(OH)₂as a absorbent were investigated. Aeration and coagulation test were carried out to evaluate variation of some factors such as COD, SS, T-N, etc. related to waste slurry treatment. The hydraulic retention time(HRT) and coagulant dosage rate were applied as operating variables in experiment. As experimental results, the reduction effects of COD, SS in aeration test were distinct, due to oxidation of SO₃ and floc, formation of suspended solids. It was also found that the reduction efficiencies of SS and T-P in coagulation test are higher than 90%.

ISO 9000 Quality System has been proved it's effectiveness in the advanced countries for years. And many companies in the world has been accepting the Quality System resulting in increasing of sales, decreasing of poor quality goods or complaints and elevating sense of quality, etc. Still, however, in the construction industrial fields, there are several problems to solve in the process of accepting the Quality System such as surveys for speciality of constructing site. If government organization in charge of operating the System, Accreditation Body, Certification Body, research institute and certificated construction companies are searching for the improving devices organically, ISO 9000 Quality System will be settled reasonably in the construction industry and become a good system to guarantee the construction quality and working system.

김영근,김수경,안기홍 한밭대학교 정보통신전문대학원 2005 정보통신전문대학원 논문집 Vol.3 No.1

정보통신의 발전은 경제 구조에 많은 변화를 가져왔으며, 향후에도 많은 변화를 예고하고 있다. 가장 대표적인 것은 경제 흐름의 근간이라 할 수 있는 유통의 변화이다. 이것은 통신망 위에 구축되는 가상의 공간에서 이루어지는 유통을 지칭하는 것으로, 빠른 속도로 발전하고 있다. 이러한 빠른 발전에도 상품데이터베이스를 구성하는 것에는 매우 불합리한 비효율성이 존재한다. 상품데이터베이스 구성의 가장 큰 비효율은 싸이트들이 개별의 데이터베이스를 구성한다는 것이다. 이런 문제를 해결하기 위해 시멘틱웹의 RDF(Resource Description Framework)언어를 이용하여 웹 온톨로지를 구성하여 공급자와 판매자간 상품 데이터를 공유하게 된다면, 전자상거래에서 상품데이터베이스 구성의 비효율성을 제거 할 수 있다. 따라서 본 논문에서는 RDF의 소개와 RDF 웹 온톨로지 편집기를 제작하고, 구성된 RDF를 참조하여 간단한 쇼핑몰을 구성하여 온톨로지를 통한 데이터의 효율적 상호운영성(Interoperability)을 증명하여, 현재 제안되고 있는 상품 카탈로그 분야의 발전에 기여하고자 한다. IT development has brought about many changes in an economic structure, and will bring about many changes in the future. The most representative thing is the change of distribution which is a basis of the economic flow. It means a distribution an a virtual space built through communication network. It has rapidly developed. However, building the product database by each site for numberless products is very unreasonable simple repeating process. To solve this problem, if the product data is shared between a supplier and seller through the web ontology by using the Semantic Web RDF (Resource Description Framework) language, an efficiency of e-commerce will be created. Accordingly, the study is intended to prove an efficient interoperability of data through ontology by introducing the RDF, fabricating the RDF web ontology editor, and building a simple shopping mall through organized RDF, and to contribute to a development of currently-proposed product catalog field.

3-次元 斜面安定 解析에 관한 硏究

金泳壽 江原大學校 産業科學硏究所 1981 産業技術硏究 Vol.1 No.-

Past research has concentrated on refining two-dimensional analysis techniques. Rather extensive comparisons of various two-dimensional methods have been made. This paper described a general threee-dimensional method of analysis by which any geometrical condition and any c, phi soil can be analyzed. The results are as follows; 1.Factors of safety computed for 3-dimensional geometry differ considerably from ordinary 2-dimensional factors of safety. 2.3-dimensional factors of safety are generally much higher than 2-dimensional factors of safety. However, situations appear to exist where the 3-dimensional factor of safety can be lower than the 2-dimensional factor of safety. 3.Teh F3/F2 ration appears to be quite sensitive to c, phi and to the slope.

It has been reported several viral diseases in soybean. The occurrence of Bean common mosaic virus and Peanut stunt virus are able to induce severe problem because the main breeding target for viral disease was focused on Soybean mosaic virus. BCMV is a spcies of the genus Potyvirus of the family Potyviridae. BCMV reduces yield by as much as 80% and also adversely affects seed quality in common bean. BCMV has a worldwide distribution because of its high rates 35% of transmission via seeds produced by plants systemically infected prior to bloom. PSV is a species of the genus Cucumovirus of the family Bromoviridae. PSV has been reported to be economically damaging on beans worldwide. Although the virus is reportedly seed transmissible at very low rates, infected plants rarely produce pods with normal viable seeds. The most satisfactory management method of viral diseases such as BCMV and PSV is the use of resistant cultivars and healthy seed. For the overcome of genetic resistance by new virus such as BCMV and PSV, virus diseases monitoring and researches need to study deeply and continually. In this study, we conducted the resistance screen on BCMV and PSV for selection of resistance cultivars. We inoculated on 128 cultivars with PSV and BCMV respectively. These cultivars were classified through pathogenic response such as resistance, necrosis and susceptibility. In addition, 99 and 66 resistant cultivars were confirmed against PSV and BCMV respectively.
