ABSTRACT
This research examined how information-seeking tactics and sense of workplace community are related to one another. Data from Korea showed that workers (n = 314) who preferred overt tactics of seeking information (i.e., direct questioning) also reported a stronger sense of workplace community. Information types and sources did not moderate the relationship between information-seeking tactics and sense of workplace community. Information types, however, moderated the relationship between importance of information and sense of workplace community and the relationship between coworker availability as an information source and sense of workplace community.

We developed a CTL vaccine vector by modification of the RPS-Vax system, a mucosal vaccine vector derived from a poliovirus Sabin 1 strain, and generated an oral CTL vaccine against HIV-1. A DNA fragment encoding a cytoplasmic transduction peptide (CTP) was integrated into the RPS-Vax system to generate RPS-CTP, a CTL vaccine vector. An HIV-1 p24 cDNA fragment was introduced into the RPS-CTP vector system and a recombinant poliovirus (rec-PV) named vRPS-CTP/p24 was produced. vRPS-CTP/p24 was genetically stable and efficiently induced Th1 immunity and p24-specific CTLs in immunized poliovirus receptor-transgenic (PVR-Tg) mice. In challenge experiments, PVR-Tg mice that were pre-immunized orally with vRPS-CTP/p24 were resistant to challenge with a lethal dose of p24-expressing recombinant vaccinia virus (rMVA-p24). These results suggested that the RPS-CTP vector system had potential for developing oral CTL vaccines against infectious diseases.

The distribution of exogenous C(14)-succinic acid by Clonorchis sinensis incubated in Tyrode medium was studied by using autoradiographic techniques. A comparison was made between macro and microautoradiographs of this worm showed that black grains derived from labeled substance were distinctly observed in parenchymal tissue, oral sucker, ventral sucker, ovary, testes, and uterine tubules with eggs. In pharynx and intestine, a low density was monitored while negligible activity was found in seminal receptacle and vitelline follicles. In studying the further details, microautoradiography was utilized. The most radioactive regions were the reticular tissue and subcuticular musculature of this fluke, closely compatible with the finding of macroautoradiography. Apparent black grains of radioactivity were also found in oral sucker, ventral sucker, pharynx, uterine tubules, eggs in uterus, and intestinal ceca. Structures showing the least radioactivity included ovary, seminal receptacle and vitelline folliciles.
