Physical properties of waterborne soft feel coatings for instrument panel were investigated. Soft feel coatings give warm and velvet touch for cold and hard plastic materials. Waterborne soft feel coating is composed with two parts. Part A contains polyester polyurethane dispersion (PE-PUD), OH-functional water dispersible polyurethane resin (PC-PUD) and OH-functional water dispersible alkyd resin (OH-PA). Part B contains hydrophilic hexamethylene diisocyanate trimer (HHDI). Soft feeling of coated panel was related with the amounts of PC-PUD and OH-PA. The physical properties of coated panel could be controlled by the NCO/OH ratio from Part A and Part B. Soft feeling was enhanced with relevant to PE-PUD content but the content of PE-PUD was limited because of weakening of coated film strength. For excellent touch and good property, the optimum composition of soft feel coat was PC-PUD(30%) and PE-PUD(20%). The results from all reliability tests satisfied soft feeling, scratch, chemical resistance and fogging.

목적 : 폐렴구균은 인체에서 폐렴, 수막염 및 패혈증 등을 일으키는 중요한 병원균으로 현재 전 세계적으로 항균제 내성이 큰 문제가 되고 있다. 하지만 폐렴구균의 항균제 내성에 따라 병독성이 어떻게 변화하는지에 대해서는 구체적으로 알려져 있지 않다. 이에 기능적 및 구조적 분석을 통하여 폐렴구균의 주요 병독성 인자인 pneumolysin의 병인론적 역할을 규명하고자 하였다. 방법 : 임상 검체에서 분리된 페니실링 감수성 균주 20주와 내성 균주 20주를 대상으로 하였다. Pneumolysin의 세포 독성의 변화를 관찰하기 위하여 각각의 균주들의 용혈능을 측정하였고, pneumolysin 유전자를 중합효소 연쇄반응으로 증폭한 후 증폭 산물의 유전자 구조를 분석하였다. 결과 : 페니실린 감수성 균주와 내성 균주간의 용혈능은 유의한 차이를 보이지 않았으나, 일부 용혈능이 매우 낮은 균주에서 Lys152→Thr, Thr-172→Ile, Lys-224→Arg와 같은 변이가 관찰되었다. 결론: pneumolysin의 세포 독성의 변화는 항균제 내성 정도와는 무관하였으나, 일부 용혈능이 저하된 균주에서 발견된 pneumolysin 유전자의 변이가 pneumolysin의 세포 독성에 영향을 주는 것으로 보인다. Background : Pnumolysin (Ply) is one of the most important virulence factors of Streptococcus pneumoniae. To investigate the functional and structural variation of Ply, hemolytic activity (HA) and gene sequences of pneumolvsin were determined. Methods : A total of 40 invasive pneumococcal isolated (20 penicillin-susceptible & 20-resistant strains) were analyzed. HA of each isolate was measured in crude extracts (1×10^8 CFU/mL) hourly from the time of inoculation to 9h. Crude extracts (50㎕) and DTT buffer (100㎕) were serially diluted in 96-well plate and mixed with 1% sheep blood (50㎕). HA was represented as the reciprocal of the greatest dilution, which resulted in the complete lysis. Two sets of oligonucleotide primers were used to amplify a 1,474-bp fragment containing the coding region and a 578-bp fragment of upstream region of ply gene, respectively. Amplified products were directly sequenced. Results : HA showed a wide variation from 0 to 87,480 regardiess of penicillin MICs, serotypes or specimen sources. Two bacteremic strains showed completely no hemolytic activity. No significant differences in HA between penicillin-susceptible (Mean± SE : 15,468± 4,693) and penicillin-resistant strains (21,384± 4,087) were found (p > 0.05).Sequencing of the coding region showed unique alterations in amino acids in strains with markedly reduced hemolytic activity (≤ 40): Thr-172-Ile and Lys-224-Arg. However, upstream region of ply gene was highly conserved. Conclusions : Ply activity was not related with antibiotic resistance. Absence of HA in some strains was associated with unique alterations in amino acid sequences in ply gene. Relationnship between genomic alteration and functional changes in pneumolysin should be further investigated.

은행경영지배구조 개선에 관한 연구

오현탁,이재갑,김병용 전북대학교 산업경제연구소 2001 전북대학교 산업경제연구소 논문집 Vol.32 No.1

경영진견제 측면만이 부각된 현 사외이사제도 중심의 은행경영지배구조는 주주가치의 극대화 및 경영효율성 제고와 투명성 확보차원에서 보면 다음과 같은 문제점이 있다. 첫째로 이사회 및 경영진의 역할이 불명확하여 경영의 성과제고를 어렵게 하고 있으며, 둘째로 대부분 위원회 의결기능이 결여되어 제 기능을 발휘하지 못하고 있고, 셋째로 개별이사 및 이사회를 평가할 수 있는 구체적인 기준이나 절차가 거의 없어 이사의 교체방안이 없다. 마지막으로 대부분 은행의 경우 경영진의 성과평가 절차 및 기준이 없거나 명확하지 못하여 경영진에 대한 보상이 제대로 이루어지지 않고 있다. 이와 같은 문제점에 대한 개선책으로는 첫째로 은행은 은행장과 이사회의장 및 이사회와 위원회의 역할과 의무를 구체적으로 명시하는 문서를 구비할 필요가 있으며 이사회 지원기능을 강화하고 경영진과 이사회간의 창구를 단일화시킬 필요가 있다. 둘째로 각 위원회에 권한을 대폭 이양하여 위원회의 기능을 활성화시킴과 동시에 이사회로의 보고체계를 확립시킬 필요가 있고, 셋째로 각 은행들의 이사회는 이사회 및 이사에 대한 성과평가를 매년 의무적으로 실시하고 평가 결과를 바탕으로 이사회의 재구성이 가능하도록 해야 할 필요가 있으며, 마지막으로 각 은행들은 은행장과 임원의 경영성과가 충분히 보상될 수 있도록 합리적인 성과평가 절차를 구축하고 보상수준과 구조를 개선할 필요가 있다.

The purpose of this study was to determine the usefluness of the UGI study with Carboxy-Methylcellulose (CMC) and 140% barium in the patient undergone gastrectomy We reviewed the UGI study with effervescent agent and barium and the UGI study with CMC and 140% barium of twenty one patients, undergone gastrectomy (Billroth-Ⅱ:12, Billroth-Ⅰ:4 total gastrectomy:5). The average interval between these studies was 19 months. The coating quality of the remnant stomach, anastomosis sit e, jejunum and proximal ileum in two studies were compared. The maximum luminal diameter of the same site and the maximum distance between a adjacent valvulae conniventes were measured for evaluating the distensibility of these studies. Compared with the coating quality of the remnant stomach, the UGI study with effervescent agent and barium was superior to the UGI study with C MC and barium in 68% (11/16) patients. The difference of coating quality between these studies was marginal in the anastomosis site and jejunum. The UGI study with CMC and barium provided a better coating quality in the proximal ileum of 95%(20/21). The maximum luminal diameter of the anastomosis site, jejunum and proximal ileum was respectively 2.75cm, 3.36cm, and 2.82cm inthe UGI study with effervescent agent and barium, 3.2cm 3.35cm, and 3.40cm in the UGI study with CMC and barium(p〈0.01). The maximum distance between a adjacent valvulae conniventes of the jejunum and proximal ileum was respectively 0.61cm and 0.51cm in the UGI study with effervesent agent and barium, 0.74cm and 0.72cm in the UBI study with CMC and barium (p〈0.05). Compared with the distensibility, the UGI study with CMC and barium was superior. The UGI study with CMC and barium in subjects, undergone gastectomy, showed the advantage the mucosa distal to anastomosis site except for the remnant stomach and must be supply the more information in finding lesion such as adhesion and peritoneal dissemination.

게임이론의 회계학 방법론적 의미

吳龍圭,吳在春 全北大學校 1995 論文集 Vol.39 No.-

There is no one universal accounting theory, but many accounting theories exist now. Of course each theory has its own paradigm. The problem is how one can choose one paradigm among many. Because paradigm shift occurs like "Gestalt switch", we can't answer this question. Although this idea about accounting theories' status prevails, positive accounting theorists attack it. They think that normative theory is not scientific theory at all. In this paper, this debate is treated as the problem of social welfare function of accounting choice. Then, normative theories supposed dogmatically the existence of the function, however positive theorists doesn't concern the objective function of theory users but their real constraints, which are known through positive theory. Game theory can be viewed to extend this line of thought and to suggest various explanations about many accounting phenomena.
