신유선 감염에 저항하는 소 방어효과는 소의 전신적인 방어기전과 유두조직의 건강에 주요한 영향이 있는 유두내 국소적 방어작용에 의하여 결정된다. 착유기에 의하여 유발되는 유두조직 장애의 정확한 평가는 착유설비와 일상적인 착오와 같은 것이 소와 관계되는 특성의 몇가지 응용이 필요하다. 유두조직의 3가지는 차이가 있다. (i) 외견과 유두상태, (ii) 해부학적 구조와 조직구성 그리고 (iii) 생리적 활동상태. 유두반응의 그런 상태 모두의 특성이 기술되어 있고, 신감염의 잠재적 위험성이 관계된다. 유두조직 측정에 추가되는 것은 분만전 우유시료와 유두관 흡수시료의 조사로 기계유발 유두조직반응 분석을 위하여 대단히 도움이 된다. 안내지침은 신감염 위험이 있을 수 있는 기계유발 유두반응평가를 위하여 제안된다.

This study examines the effect of general corporate employees' perception of organizational politics, which is widespread and negatively perceived in Korean companies, on their reaction behavior. In particular, the mediating effect of cynicism and the moderating effect of commitment was analyzed. As a result of the analysis, it was confirmed that organizational political perception had a positive effect on cynicism, and cynicism had a significant effect on exit, loyalty, and neglect. In addition, the moderating effect of commitment between cynicism, exit, and neglect was confirmed. Through this study, it was demonstrated that the higher the organizational political perception, the higher the cynicism and the negative reaction behavior. It was intended to suggest the organizational system improvement and the importance of human resource management through it.

The purpose of this study is to investigate the interaction effects of organizational context, customer reaction, and job burnout in Senior Welfare organizations. In addition, we will analyze the moderating effects of demographic characteristics (personal characteristics, organizational characteristics). A total of 796 social workers engaged in Senior Welfare projects were analyzed. As a result, the following results were obtained. First. It was found that there was a significant difference between the variables in the sociodemographic characteristics, organizational context, customer reactions, and interaction effects on job burnout. Second, age, employment type, and Social Worker qualifications were the most important variables of control effect. The specific organizational behavioral factors between the employees and the users should be studied.

Snailfish usually lives at the bottom of the sea and showed typical retrogressive change with specialized tissue structures of skin and skeletons. In order to obtain the specific genes of snailfish, highly expressed in the body, we made subtracted cDNA library and analyzed 200 clones. Totally 200 clones were obtained and sequenced, and among them 62 clones were turned out to be homologous to the known gene, i.e., thioesterase (9), myosin (8), creatine kinase (7), skeletal alpha-actin (6), parvalbumin b (5), ribosomal protein (5), type I collagen (3), muscle troponin (3), dopamine receptor (2), histatin (2), and heat shock protein (2), cystatin (1), lectin (1), statherin (1), secretory carrier membrane protein (1), keratin type I (1), desmin (1), chloroplast (1), muscle tropomyosin (1), reticulum calcium ATPase (1), ribonucleoprotein (1). The remaining 138 clones were low homologous or non-redundant genes through Genbank search. Especially 5 clones were novel and specifically expressed in the body tissues of Snailfish by in situ hybridization. Therefore, we analysed these 5 clones to identify the C-terminal protein structures and motifs, and partly defined the roles of these proteins in comparison with the expression patterns by in situ hybridization. C9O-77, about 5000 bp, was supposed to be a matrix protein expressed strongly positive in epithelium, myxoid tissue, fibrous tissue and collagenous tissue. C9O-116, about 1500 bp, was supposed to be a transmembrane protein which was weakly expressed in the fibrous tissue, epithelium tissue, and myxoid tissue, but strong in muscle tissue. C9O-130, about 1200 bp, was supposed to be an intracytoplasmic molecule usually in the epithelial cells. C9O-161, about 2000 bp, was weakly expressed in epithelium, muscle tissue and myxoid tissue, but specially strong in epithelium. C9O-171, about 1000 bp, was supposed to be a transcription factor containing zinc finger like domain, which was intensely expressed in the epithelium, muscle tissue, fibrous tissue, and in collagenous tissue.

The study aims at verifying the effect of the image, trust and responsiveness to social welfare organizations on continuing the sponsorship of private donors, the mediating effect of the organizational identification and the moderating effect of their financial status. As a result of causal analysis of the variables by structural equation models, regardless of donors' financial status, social welfare organizations' image, trust and responsiveness has no direct effect on continuing the sponsorship. Among the donors in relatively good financial status, social welfare organizations' image, trust and responsiveness positively have direct effects on organizational identification, which has a direct effect on continuing the sponsorship. That is, the image, trust and responsiveness influence the continuity of the sponsorship through the full mediating effect of organizational identification. On the other hand, among relatively poor donors, only the organizations' image and trust positively influence the organizational identification, The direct and indirect effects on the continuity of the sponsorship are different according to the private donors' financial status, which means that the moderating effect of the donors' financial status is proved. The result of latent mean analysis regarding 5 main latent variables according to the private donors' financial status, shows the significant difference in the continuity of sponsorship only(Mean= .197, Cohen's D=.779). By emphasizing that Organizational identification is a critical factor in terms of enhancing the continuity of sponsorship, some practical implications are discussed based on the study's findings.

In a rapidly changing corporate environment, the relationship among organizational justice, job attitude, and cynicism as factors influencing exit, voice, loyalty, and neglect that can promote the performance improvement of organizational members was analyzed with the PLS (Partial Least Squares) structural equation in two stage approach. Organizational justice constitutes a formative secondary factor by the first order of distributional justice, procedural justice, and interactional justice, and job attitude is a formative secondary factor of job satisfaction and organizational commitment. We analyze the direct and indirect effects by mediating relationships of cynicism and job attitude on the factors such as exit, voice, loyalty, and neglect. From the perspectives of knowledge management, we analyzed how the perception of organizational justice affects the overall performance of the organization through the improvement of the employees' performance.

Kinetic parameters for the texture degradation of three varieties of sweet potato during heating were determined using two alternative methods, the biphasic model and the fractional conversion method. The texture degradation of sweet potatoes during heating could be expressed by two simultaneous first order reactions using the biphasic method, whose activation energies were ranged $71.0{\sim}75.1\;kJ/mol\;and\;48.4{\sim}59.6\;kJ/mol$ for the initial fast texture degradation reaction and the slow texture degradation reaction at a prolonged heating period, respectively. However, the whole texture degradation phenomena of sweet potatoes during heating could also be explained by a single first order reaction using the fractional conversion method. The activation energies were $67.5{\sim}75.3\;kJ/mol$, which were comparable with those of the first phase reaction for the texture degradation determined by the biphasic model. A kinetic compensation effect shown between the kinetic parameters determined by both methods indicates that both methods can be conveniently used to determine kinetic parameters for the texture degradation of sweet potatoes by heating.

배경 :폐포내 fibronectin(FN)의 분포와 역할은 많은 연구자에 의하여 연구되어왔다. 흰주에서 폐의 분화시 FN은 태자에서 폐포의 기저막에 주로 분포되고 간엽조직에서도 관찰되면 분화가 진행되면 폐포막의 간질조직에 FN의 함량이 높아진다. 또 FN은 일반적으로 폐포대식세포(alveolar macrophage)에서 분비되고 폐에 질병이 발생하였을 때 다량의 FN이 폐포대식세포에서 분비된다고 보고되어 있다(Schoenberger 등 1984: Ozaki 등 1990; Rom 등 1987 ; Cordier 등 1990) 저자는 흰쥐의 폐포발생이 진행중인 폐포기 후반에서의 폐포막내 정상적인 FN이니 분포의 변화와폐포를 구성하는 큰 폐포세포(type II pneumocyte)에서의 FN의 분비여부를 면역조직염색법과 전자현미경을 이용하여 추적하고자하였다 실험대상 및 방법: 청정동물실에서 사육한 SPF 흰쥐(Sprague-Dawley 계)를 임신시켜 질도말법을 이용하여 태령을 정한 뒤 태아제 17일 및 20일 출생 제 1일, 2일, 3일, 5일, 및 7일의 신생흰쥐를 실험동물로 사용하였으며 대조군의 흰쥐는 체중 200ㅎ의 건강한 수컷을 사용하였다 흰쥐의 폐조직은 면역조직염색을 위해 rabbit anti rat fibronectin polyclonal antibody를 일차항체로 biotinylated goat anti rabbit IgG를 이차항체로 사용하여 폐실질세포내 FN의 분포를 LM으로 관찰하였고 한편 폐포막을 구성하는 세포 중 큰폐포세포가 FN을 분비하는 세포인지를 추적하기 위해 금과립을 첨가한 항체를 사용하여 큰 폐포세포내 FN의 분포를 EM을 이용해서 추적한 결과 다음과 같은 결과를 얻었다 결과 : 제 17일 및 20일 태아시기의 폐에서의 혈관주위에 강한 FN반응이 관찰되었다 출생후 폐포막의 FN의 활성은 출생후 5일 및 7일에 최고주에 달했다. 출생직후 1-2일경에 혈관의 조직내 FN의 활성이 양성을 나타내지만 3일이후 활성이감소되었다. 폐포대식세포내 FN의 활성은 출생후 증가되었다. 폐조직내 소기관지의 FN의 활성은 출생후 완만하게 상승되었다. 큰 폐포세포는 출생 1-3일에 일정량의 FN 반응이 세포질과 미세융모내에 관찰되었다. 결론 : 이상과 같은 결과로 흰쥐의 폐포의 분화과정이 계속되는 출생후 폐에서 FN의 분비는 7일이내에 성숙흰쥐의 폐포내 반응과 비슷한 반응으르 보이며 이때 폐의 실질조직은 분화가 거의 완료되었을 것으로 사료되었고 큰 폐포세포에서도 FN이 분비되는 것으로 결론지울수 있다.
