The planing hull is characterized by a large change in the posture according to the speed, and the shape of the propeller varies, so that the hull resistance varies greatly depending on the propeller used. Especially, the Savitsky system, which is widely used for estimating the resistance of planing hull, does not consider the characteristics of these propeller and ship bottom spray rails. In this paper, in order to investigate the difference in resistance characteristics between the propeller and the bottom of the propeller of 6m and 12m class propeller using propeller such as outboard or stern drive, A comparative test was conducted on resistance and attitude posture changes in the Circulating Water Channel of Institute of Medium & Small Shipbuilding. As a result of comparison test, it was confirmed that there is a clear difference in the attitude change due to the presence of the bottom floor spray rail and the change in resistance characteristics due to the installation of the propeller. However, attitude change with the propeller was found to be insignificant.

This study aimed to investigate primary students' science-related attitudes through the literature review. Ninety-four papers published in domestic science education journals, since 1990, were collected and were followed by content analysis. In this study, science-related attitude was conceptualized as attitude toward science, scientist, science-related occupations, and school science, which is composed of cognitive, affective and behavioral domains. Based on the conceptualization, the instruments used for measuring students' attitudes were analyzed. The analysis of definition of science-related attitude in the articles showed different foci on cognitive, affective and behavioral domains. To suggest the effective instruction for enhancing students' science-related attitudes, this study identified students' attitude with gender, grade, residence and achievement level. The result showed that male, urban, higher-grade and better performed students had more positive attitude than female, rural, lower-grade and less performed students. As for the factors in science-related attitude, I categorized the factors into personal, environmental and pedagogical aspects, and found that psychological elements in all domains were most influential to students' change of science-related attitudes. It is interesting to note that students showed dichotomous views about experiment and that task-oriented instruction failed to enhance students' attitude. Based on the research findings, this study suggests effective instruction for improving students' attitudes and future research for science education.

Among many remedial approaches against the increasing unfavorableness toward school science, one of the prevalent findings studied by affective experts is that students' achievement in science and their attitude toward it has a relatively weak relationship. In contrast, cognitive experts assert that the conceptual change involves more than cognitive aspects, and may be influenced by affective factors such as beliefs, motivation, learning attitudes, and sociocultural contexts. The latter regards continuous conceptual change as leading to better student understanding of science with variables of students' attitude toward science. As an initial step toward illuminating the affective-cognitive learning aspects of science, the purpose of this study is to develop an instrument for analyzing the relationship between students' conceptual understanding and affective factors. Cognitive questionnaires from the database of distribution in students' misconceptions of physics (DMP project), and affective questionnaires from the Relevance of Science Education (ROSE project) are integrated into our instrument. The respondents are high school students in Okayama prefecture, Japan. Through the pilot test, the authors integrated attitude toward science (AS) and interest inventory (II) from ROSE into cognitive understanding (CD) from DMP. Statistical methodologies such as factor analysis and item total correlation theoretically discerned the effective sixty-three items from the two original item pools. Having discussed two validity issues, the authors suggest ongoing research associated with our affective-cognitive research perspective.

Purpose - The objective of this research is to a) examine the effects of online reviews, posted on online distribution channels, on the change of consumers' attitudes and booking intention by distinguishing three types of online review valence: positive, negative and neutral review valence, and b) to investigate the combined effect of the inclination of online review and perceived usefulness of reviews on consumers' attitude change. Research design, data, and methodology - An experimental design was used by creating a mimicked hotel company's website and online reviews extracted from several online distribution channels such as online travel agencies (OTAs). A total of 414 respondents were randomly assigned to a type of review valence. Results - The results showed that the valence of positive reviews has a significant effect on the positive change of attitude and booking intention. However, the effect of the valence of negative reviews on the change of booking intention was not statistically significant compared to that of the valence of neutral reviews. Conclusions - The results offer some insights into the effect of online reviews on consumers' decision making processes and have important managerial implications for companies that operate online distribution channels in terms of their online marketing and the distribution of service products.

The purpose of this study is to investigate the effectiveness of academic achievements, science process skill and scientific attitude. The subjects of this study were 68 fourth-grade elementary school students who were 33 students for the 5E learning cycle instruction and 35 students for traditional instruction. The control group was taught with traditional teaching method, while the experimental group was taught 'the change to the volume of material due to heat' unit of 4th grade with the developed learning cycle model. The results were as fellows: First, the learning cycle instruction is more effective for understanding of a concept related to the change to the volume of material due to heat. Second, the learning cycle model seems more effective for the expansion of both scientific inquiry ability and scientific attitude.

It is not to observe that a decision-maker frequently changes his choice strategy in the repetitive gamble choice situation. This change in risk preference attitude, however, is not well explained with the existing gamble choice models, such as Bell's disappointment-elation model which is an interesting extension of the classical MEU model. This paper shows that this change in risk preference attitude should be interpreted as a systematic transition of "d" and "e", the disappointment and elation constants of Bell's model repectively. A laboratory experiment is also performed to identify the factors which greatly affect the decision-makers' risk preference attitude change. The number of consecutive successes/failures and the amount of remaining capital found to be statistically significant factors.significant factors.
