In 2007, the Korean Society of Infectious Diseases recommended an immunization schedule for adults residing in Korea. This recommendation includes four categories: standard immunization for healthy persons, supplementary immunization for persons with underlying illnesses, recommendations for health-care personnel and for international travelers. The Standard Immunization Schedule consists of universal vaccination (tetanus-diphtheria/tetanus-diphtheria-pertussis (Td/Tdap); hepatitis A vaccine for persons aged 20s; human papilloma virus vaccine for women under 26 years old; meningococcal vaccine for military recruits and college students in dormitories; influenza vaccination for persons aged 50 years or more and pregnant women; and pneumococcal vaccination for persons aged 65 years or more) and catch-up vaccination (hepatitis A vaccine for persons aged 30s; hepatitis B vaccine, varicella and MMR vaccines for persons who have uncertain specific immunities). The Supplementary Immunization Schedule recommends 4 vaccines, i.e., pneumococcal, influenza, meningococcal, and Haemophilus influenzae type b, appropriate to the underlying illnesses, and confirmation of the presence of antibodies to hepatitis A and hepatitis B. The Recommendation for Health-Care Personnel includes universal vaccination (influenza and pertussis) and catch-up vaccination (hepatitis B, measles-mumps-rubella and varicella for seronegative health-care personnel). The Recommended Immunization for International Travelers focuses reinforcement of vaccinations for healthy persons and includes certain immunizations necessary for international travel (yellow fever, meningococcal, plaque, tick-borne encephalitis, and cholera).

CRP (cAMP receptor protein)은 cAMP와 결합하여 cAMP-CRP 복합체를 형성하여 전사조절의 조절인자로서 작용한다. crp 유전자에 변이를 도입하여 cAMP의 비존재 상태에서 cAMP-CRP와 비슷한 기능을 가진 crp* 유전자가 도입된 대장균 MK2001 (crp*¹, cya::km)을 숙주로 사용하여 cAMP 혹은 cGMP의 비존재하에서도 mal 유전자의 발현을 촉진시키는 유전자 sfs (sugar fermentation stimulation) 수 종을 클로닝하였다. 본 실험에서는 이미 밝혀진 nlp (Ner like protein) 유전자와 같이, sfs의 새로운 유전자를 탐색하여, 그 중 sfs4의 2126bp 전 염기배열을 결정하고, 잠정적인 sfs4의 promoter 영역에는 CRP 단백질과의 결합 DNA 공통 염기배열(5' AAT TGTGA ACACCA TCACC CGT 3')이 존재함을 확인했다. lacZ 융합 유전자를 작성하여 TP2010R1과 MK2001의 균주에서 cAMP를 첨가할 경우 각각 2.3배, 1.8배의 β-galactosidase 활성이 증가 하는 것으로 보아 sfs4는 cAMP-CRP에 의해 발현 조절을 받는 것으로 나타났다 In Escherichia coli, CRP forms a complex with cAMP and acts as a transcriptional regulator of many genes, including sugar metabolism operons. The E. coli MK2001, which is introduced the altered crp*¹, is functional in the expression of lac, ara and man, in the absence of cAMP. However, the expression of mal gene is fully activated by the addition of cAMP or cGMP. The object of the study is cloning of the sfs (sugar fermentation stimulation) genes, which was involved in regulation of mal gene expression with the altered crp*¹gene, and structural analysis and characterization of the genes at the molecular level. We have cloned 5 different E. coli genes which stimulate the maltose metabolism in a crp*¹, cya::km (MK2001) background. Newly identified genes were designated as sfs. One of the sfs genes (pPC1), located at the 53.2 min map position in the E. coli chromosome, was further analyzed. Expression of the genes, which is involved in maltose metabolism, malQ (amylomaltase), was increased to 5.8-fold in the presence of a plasmid, pAP5, containing the subcloned sfs4 gene. The nucleotide sequence of a common 2,126bp segment of the pPCM1 was determined and two open reading frames (ORF1 and ORF2) were detected. The ORF1 encodes the sfs4 gene and ORF2 encodes a truncated protein. Potential CRP binding site is located in the upstream of the putative promoter in the regulatory region. Expression of the cloned sfs4 gene was positively regulated by the cAMP-CRP complex.

The preparation conditions of alumina powder extracted by hydrochloric acid from domestic San-Cheong kaolin have been investigated. In order to obtain best conditions to extract alumina by hydrochloric acid, experiments carried out with various acid concentrations, reaction temperatures, reaction times, and pH. The optimum conditions were 20 wt.-% for hydrochloric aicd concentration, 100℃ for reaction temperature, 7hrs for reaction time and pH8. The yield of alumina found to be 89.2wt.-% under these conditions. Two drying methods, direct and ethanol distillation drying method to control the precipitated agglomeration have deen compared. The ethanol distillation drying method revealed more narrow particle size distribution and less agglomerate than the direct drying method.

마르크스主義 社會正義論에 關한批判的 硏究

최일성,홍용희,노병철 忠州大學校 2003 한국교통대학교 논문집 Vol.38 No.1

This dissertation attempts to examine the theories of social justice in Marxism. The Marxist critique of justice requires us to raise the issue of whether justice has a distinctive meaning beyond conformity to established rules and practices and, if so, if this can be distinguished from and related to other social and political ideals. Marx's contention is that rights and justice are essentially bourgeois ideas which impress the ideology of capitalist economic organization. If justice is indeed an intrinsically capitalist concept, then it is predictable that those who propound a normative theory of justice will express the values of bourgeois individualism. There is a good deal of textual evidence for Marx's theoretical amoralism and his anti-justice and anti-rights stances. Certainly Marx did not think that juridical concepts like justice have any significant role to play in the explanation of social structure and social change. Nevertheless Marx's radically different starting-point implies that a socialist theory of justice must differ from liberal theories not only in the content of its principles but also in the function which it allots to justice discourse. Marx rejected Mill's choice criterion of value and Rawls' conception of deliberative rationality as individualistic abstractions. Especially the concept of exploitation plays a key role in Marx's attack on capitalism. Marx's views on justice and rights rejected the idea that juridical conceptions are the most fundamental conceptions for explaining social phenomena. This rejection of the juridical model is, of course, an inference from Marx's materialist views on the relation between the base and the superstructure of a given society. Marx concludes that juridical conceptions of justice and rights play neither a major explanatory nor a major critical role. Marx is committed to a very radical position on the state and social justice. We argue that this radical evaluative perspective is more epistemological than moral in any traditional sence.

Wear of blades, buckets, plates and chisel occurred in operation of construction machinery, agricultural equipments, earthmoving equipments and offshore structures cause earlier failure of the components, resulting in the increased energy consumption, cost of maintenance and replacement. To solve the problems, advanced materials with higher resistance to abrasive wear have been attempted to make through alloy design and hot deformation followed by air cooling. 0.25C-1.4Mn-1.0Cr-0.7Ni-0.2Mo-0.08V-0.02Cu steels produced by hot forging were cooled in air to form bainite, showing higher resistance to wear than any other steels with different chemical composition in the sliding wear tests under the applied load of 74N. Higher strain hardening during sliding wear of 0.25C-1.4Mn-1.0Cr-0.7Ni-0.2Mo-0.08V-0.02Cu steels to cause microploughing wear mode seems to be one of the main reasons for showing higher resistance to wear than any other steels in this study.

This study is to investigate complaining behavior of consumers who purchase fashion products on the inter-net, as well as to find how the complaining behaviors are related to the consumers' characteristics. The subjects of this study are limited to the consumers who have experienced dissatisfaction when purchasing fashion products through the internet. The questionnaires were administered to male and female respondents using the internet shopping mall. The results can be summarized as follows: The factor analysis shows that consumer complaining behaviors are fitted well into four factors(direct complaining behavior, private complaining behavior, third-party complaining behavior, and no response). In the difference analysis by consumer's complaining behavior styles and gender, private complaining and third-party complaining behavior were significant statistically. In the difference analysis between consumer's complaining behavior styles and internet self-efficacy. Internet self-efficacy was significantly different according to consumer's complaining behavior styles, especially for direct complaining, third-party complaining and no response. Private complaining behavior, third-party complaining behavior and no response were negatively related to consumer retention, while direct complaining behavior was not.

This study aims to discussion analysis of actual condition and spatial organization characteristics of Italian Medici villa gardens in 15th century. In this study was selected the cases of the 5 gardens that were constructed as the suburban house of Podesta Medici family in 15th century. To do this, it was studied in two ways: Analysis of the present conditions and photographing, research materials about the form of physical structure and review historical documents. The result of analysis in the sight of the location and spatial structure was good matched. At the beginning, he concept of construction of the Medici villa gardens had been expressed as intrinsic nature and an ideal of a quiet life of suburb, enjoying of nature of philosopher, poets, politician etc.. The spatial organization of the Medici Villa gardens was built the hill area where were located in a very good geographical feature with nice looking at mountains and rivers. In the exterior space patterns of the Medici Villa gardens was imported borrowed scenery of surrounding landscape and while placed arranging various constituent elements of the casino, terrace, parterre, ninfeo, grotta in trying to formalize the landscape. The result of this study, the political and social, technical phenomena which constitute the physical construction pattern affected the locational property and the spatial organization of the neighbor on Medici Villa gardens.

Apo B-100 is a constitutive component of low density lipoprotein (LDL) of which functions in packaging, transport and absorption of lipids Extortive binding of anti B_(4)-antibody onto the Apo B-100 should inhibited the functions of Apo B-100 Previously we had showed that the peptide B_(4) induced antibodies recognized Apo B-100 and thus elicited anti-obesity effect In this study we compared the efficacy of antibody inducing immune responses by introducing additional peptides fused to the C-termninal of B_(4) peptide We constructed TB_(4) hybride peptide of B_(4) with preS2 of HBV and B_(4)N another epitope orientation of chimeric TB_(4) Among these three artificial peptides B_(4)N was the most efficient inducer of the antibody against B_(4) These result explains that the B cell epitope and T-helper cell epitope orientation is very important factor to determine the antigenicity to humoral immunity. Apo B-100은 LDL에서 지방을 포장, 흡수, 운반하는 기능을 수행하는 단백질이다. Apolipoprotein B-100(Apo B-100)에 대한 특이 항체의 결합은 LDL의 정상 기능을 방해한다. 선행 실험에서 Apo B-100의 모조 펩타이드인 B_(4)가 Apo-B-100을 교차 인식하는 항체를 유도하고, 비만 억제 효과를 나타내는 것으로 밝혀졌다. 본 연구에서 B_(4)펩타이드의 C-terminal부분에 펩타이드를 융합, 첨가하므로 면역반응에서 항체유도의 면역응답반응에 어떠한 효과를 나타내는지 비교해 보고자 하였다. B_(4)펩타이드의 N-말단에 HBV의preS2 펩티드를 융합시킨 B_(4)T의 N-말단데 또다른 B세포 에피도프 펩티드를 융합시킨 B_(4)N을 작성하였다, 세종류의 하이브리드 펩타이드 중에서 B_(4)N이 B_(4)에 대한 항체유도능이 가장 효율적이다,. 이상의 결과로 B cell epitope과 T-helper cell epitope의 방향성이 체액성 면역 반응에서 항원유도능을 결정하는 중요한 요소임을 확인하였다.
