  • A new set of functional group interaction energy descriptors relevant to the ACE (Angiotensin-Converting Enzyme) inhibitory peptide, QSAR (Quantitative Structure Activity Relationships), is presented. The functional group interaction energies approximate the charged interactions and distances between functional groups in molecules. The effective energies of the computationally derived geometries are useful parameters for deriving 3D-QSAR models, especially in the absence of experimentally known active site conformation. ACE is a regulatory zinc protease in the renin-angiotensin system. Therapeutic inhibition of this enzyme has proven to be a very effective treatment for the management of hypertension. The non bond interaction energy values among functional groups of six-feature of ACE inhibitory peptides were used as descriptor terms and analyzed for multivariate correlation with ACE inhibition activity. The functional group interaction energy descriptors used in the regression analysis were obtained by a series of inhibitor structures derived from molecular mechanics and semi-empirical calculations. The descriptors calculated using electrostatic and steric fields from the precisely defined functional group were sufficient to explain the biological activity of inhibitor. Application of the descriptors to the inhibition of ACE indicates that the derived QSAR has good predicting ability and provides insight into the mechanism of enzyme inhibition. The method, functional group interaction energy analysis, is expected to be applicable to predict enzyme inhibitory activity of the rationally designed inhibitors.

  • The purpose of this study was to analyze the effect on the level of subject interest and interaction when supporting scaffolding considering learner characteristics in PBL. For the study, the participants were 86 college students. The research procedure was as follows. First, we divided the experimental group and the comparative group. A primary PBL was used to measure prior levels of subject interest and interaction. Secondary PBL was performed to verify treatment effect. In the second PBL, the experimental group received cognitive, metacognitive, and motivation scaffolding that reflected the learner's characteristics. The control group received random scaffolding. Subject interest and interaction were measured after the end of the second PBL. Collected data were analyzed using ANCOVA. As a result, the interest and interaction level of the experimental group was analyzed to be higher than that of the control group.

  • The purposes of this study were to categorize the type of student-student interaction and analyze the pattern of group interaction by cognitive level in interactive science inquiry experiments. For this study, two homogeneous and two heterogeneous groups by cognitive level were selected. Social interactions during group discussions were audio/video taped. The types of student's interaction were classified as intellectual and emotional aspects. Intellectual aspects were consisted of asking question, response, making suggestion, receiving opinion and then further coded by interaction level. Emotional aspects were consisted of relevance to behavioral participation, relevance to students' feeling, reaction to opinion. Interaction frequency in the intellectual and emotional aspect between homogeneous and heterogeneous group were compared to analyze interaction pattern. The results of this study showed that in intellectual aspect the frequency and quality of interaction in homogeneous group was higher than that in heterogeneous group. In emotional aspect. homogeneous group more showed such negative attitude as lack of confidence and dissatisfaction than heterogeneous group, on the other hand showed acceptable mood to be able to accept or object to peer's opinion. Some educational implications were drawn.

  • This paper investigates how servicescape perception influences customer experience quality in hedonic service settings. In addition to the direct effect of servicescape quality on customer experience quality, the indirect effects of servicescape quality on customer experience quality via employee-to-customer interaction quality and peer-to-peer interaction quality are also investigated. We collected data through a self-administered survey. The proposed relationships were tested using structural equation modeling. The results show that servicescape quality influences customer experience quality both directly and indirectly through employee-to-customer interaction quality and peer-to-peer interaction quality, and customer experience quality influences customer loyalty. Additionally, we find that the indirect path via peer-to-peer interaction quality is significant only in a low-satisfaction customer group. The indirect effect of servicescape quality perception through peer-to-peer interaction quality is significant only in low-satisfaction customer groups. Therefore, if evaluations for this indirect effect fall below an acceptable level, it should be addressed first before improving on other attributes. However, after this point, further improvements offer few if any gains; therefore, service firms should allocate their resources to quality improvements to other factors. This study is the first to investigate the indirect effects of servicescape quality on customer experience quality via peer-to-peer interaction quality in hedonic service settings. Additionally, this study demonstrates that the significance of this indirect effect applies only to a low-satisfaction customer group.
