Gllosy Ground Coat 에 의한 주철법랑에 관한 연구
이희수,강인찬 대한금속재료학회(대한금속학회) 1970 대한금속·재료학회지 Vol.8 No.2
Gllosy Ground Coat에 의한 습식 鑄鐵琺瑯製造에서 가장 문제시 하고있는 점은 Coat와 素地金屬과의 密着性, Cover Coat의 硬度 및 Coat層의 發泡現象이다. 이들을 重視하여 Castings의 組成과 두께에 따른 영향, Ground Coat 組成에 따른 영향 및 燒成條件에 따른 영향등을 구명하였다.

The Third Waves, witten by futurist Alvin Toppler in the 1980s presents a scenario of the information society, and it accurately indicates the direction of the information revolution. He argues that the future society will become an information society, and that the first wave, the agriculture revolution, developen through thousands of years, whild the second wave, the industrial revolution, progressed through about 300 years. The third wave, or the information revolution, according to the author, will be realized only within twenty to thirty years. As the author predicted, the 21st century is already a highly information and intelligence-based society. Benefits and losses ard determinde not by materialistic differences, but by the digital divide. Accordingly, information today is for more valuable than it has been in the past, and therefore, people have to concentrate on the ability to know something rather than on the toward the end of the 20th century has been making the lives of many more convenient in numerous ways. This influences the acquiring and the use of information. The search for information through the internet, and the production administration, preservation, and the accounting of products though barcodes, alogn with areas involved with currency has been improved due to development of information. In addition, the contribution that the simplifying of large, complex data to practical information that humans can posses has brought has been enormous. However, as much as computers may be convenient, it is still the human geing that creates the information, meaning that the distinguishing of information according to the human eye is the most basic and accurate method. In this matter, the doject of this us look at the library, which has been in existence for thousands of yearh. Here, the sources of information, or the books, were collected and arranged accordingly, while the user has been able to find the wanted book through a systme of information known as the call number. The call number is composed of the classification number, author, and the title, and the most important characteristic of the call number would be the classification number. the classification number is what determines the arrangements as foar as shelf location goes, and it can be said that the decimal classification system is generally used. 도서관 관리에 있어서 지속적으로 반복되고 중요한 업무는 대출되고 반납된 도서, 혹은 열람실 내에서 이용되고 제자리에 꽂지 않은 도서들을 서가에 순서에 맞게 재배치하는 업무로 이는 서가 관리업무의 대부분을 차지한다고 할 수 있다. 이 배열 과정에서 도서관 사서 또는 배열 보조 인력은 도서관 장서의 블랙박스인 청구기호가 적힌 레이블에 의해 순서대로 작업하게 되는데 청구기호 중 배열의 우선순위는 분류기호이고 이것에 의해 배열의 80-90%가 결정되는 것이다. 근대적인 도서관이 생긴 이래 세계 어느 도서관을 막론하고 종래의 방법대로 배열해 오고 있지만 좀 더 효과적인 배열과 검색, 관리업무 등을 추구하고자 분류기호의 칼러 테잎 적용을 생각하게 되었고 본고에서는 과연 이를 적용할 때 업무의 효율성이 수치적으로 얼마나 증대되며 여타 어떠한 도움이 따라 오는지를 알아보고자 한다.

Foeniculum vulgare Mill. (fennel) is used to flavor food, in cosmetics, as an antioxidant, and to treatmicrobial, diabetic and common inflammation. No study to date, however, has assessed the anti-inflammatoryeffects of fennel in experimental models of inflammation. The aims of this study were toinvestigate the anti-inflammatory effects of fennel in model of lipopolysaccharide (LPS)-induced acutelung injury. Mice were randomly assigned to seven groups (n=7∼10). In five groups, the mice wereintraperitoneally injected with 1% Tween 80-saline (vehicle), fennel (125, 250, 500μ l/kg), or dexamethasone(1 mg/kg), followed 1 h later by intratracheal instillation of LPS (1.5 mg/kg). In two groups,the mice were intraperitoneally injected with vehicle or fennel (250μ l/kg), followed 1 h later by intratrachealinstillation of sterile saline. Mice were sacrificed 4 h later, and bronchoalveolar lavage fluid(BALF) and lung tissues were obtained. Fennel significantly and dose-dependently reduced LDHactivity and immune cell numbers in LPS treated mice. In addition fennel effectively suppressed theLPS-induced increases in the production of the inflammatory cytokines interleukin-6 and tumornecrosis factor-alpha, with 500μ l/kg fennel showing maximal reduction. Fennel also significantly anddose-dependently reduced the activity of the proinflammatory mediator matrix metalloproteinase 9 andthe immune modulator nitric oxide (NO). Assessments of the involvement of the MAPK signalingpathway showed that fennel significantly decreased the LPS-induced phosphorylation of ERK. Fenneleffectively blocked the inflammatory processes induced by LPS, by regulating pro-inflammatory cytokineproduction, transcription factors, and NO.
