  • An excitation table is commonly used for vibration and ride tests for parts or assemblies of automobiles, aircrafts, or other heavy systems. The authors have analyzed several kinematic properties of an excitation table that is under development for heavy transport vehicles. It consists of one table and 7 linear hydraulic actuators. The authors have performed mobility analysis, inverse kinematics, forward kinematics, and singularity analysis. Especially, we have proposed a fast forward kinematic solution considering the limited motion of the excitation table. On the assumption that the motion variables such as rotation angles and displacements are small, the forward kinematic problem is converted to the observer problem of a linear system. This provides a fast solution. Also we have verified that there are no singularity points in the working range by numerical analysis.

  • This paper introduces a fast Fourier transform (FFT)-based spectral analysis method for the transient responses as well as the steady-state responses of linear discrete systems. The force vibration of a viscously damped three-DOF system is considered as the illustrative numerical example. The proposed spectral analysis method is evaluated by comparing with the exact analytical solutions as well as with the numerical solutions obtained by the Runge-Kutta method.

  • The purpose of this study was to identify the differences in shopping orientation and clothing benefit sought of a group of consumers according to the preference for fast-fashion. Data were collected from a questionnaire conducted on 416 female adults. The results were as follows. First. the factor analysis used to identify shopping orientation involved the following five factors: hedonic. economic. convenient. brand-oriented. and relation-oriented. The dimensions of the clothing benefit sought consisted of fashion. social status. practicality. figure flaw compensation. and sex appeal. Second. the differences in shopping orientation and clothing benefit sought according to the preference for fast-fashion were identified using a t-test. The consumer group preferring fast-fashion exhibited a hedonic. convenient shopping orientation. and the non-preferring group exhibited an economic. brand-oriented shopping orientation. The consumer group preferring fast-fashion pursued fashion and sex appeal clothing benefits. and the non-preferring group pursued social status and practicality clothing benefits.

  • The purpose of this study is to reduce the fast neutron fluence at the reactor pressure vessel(RPV) and to provide a basis for plant-life extension. In this study, different neutron absorbers were employed in the core outer assemblies of Kori Unit 1 Cycle 14. The modified assemblies were used to calculate fast neutron fluence at the RPV and to evaluate reduction of outer assembly power and total power in core. By comparison with the case of no suppression fixture, the fast neutron fluence of a case with two rows stainless steel around the assembly with natural uranium pins is decreased by 85.8%. It is noted that the modification of outer assembly is more efficient than the previous low leakage loading pattern (LLLP) applied to Kori Unit 1. Also, compared fast neutron fluence in Cycle 1 with Cycle 14, fast neutron fluence at the RPV between Cycle 1 and Cycle 14 is not significantly different. It is found that LLLP applied to the Kori Unit 1 has not contributed to fast neutron fluence reduction at the RPV.

  • The study purpose was to investigate the factors related to fast food consumption of university students. Factors were identified using the Theory of Planned Behavior. Based on the pilot study, 18 behavioral beliefs, 7 normative beliefs and 19 control beliefs were identified. Data (n = 269) were analyzed using analysis of variance or $X^2$,/TEX> tests. Subjects were categorized into non-users (27.9%), users (42%) and frequent users ( $\geq$ 2 times/week, 30.1%). Regarding behavioral beliefs, users or frequent users responded more positively on advantages of eating fast foods including ‘taste’ (p < 0.001), ‘making me feel full’(p < 0.001), ‘diverse menus’(p < 0.05) than non-users. Compared to users, non-users responded more positively on the item that eating fast foods leads to eat vegetables less (p < 0.05), and negatively on ‘making me eat more salt’(p < 0.05). Most of the referent groups, parents (p < 0.001), sisters/brothers (p < 0.01), relatives (p < 0.01), friends (p < 0.05), boy/girl friends (p < 0.05) were important sources of influence regarding subjects' fast food consumption. Users or frequent users felt less control over factors or situations that make it consume fast foods (9 out of 19 control beliefs). These factors included; availability issues (p < 0.001), ‘not having other foods on hand’(p < 0.01), ‘others eating together like fast foods’, ‘convenience’, ‘social increase in fast food use’, ‘easy to get fast foods anytime’(p < 0.05). In addition, users of fast foods were more likely to eat fast foods when they don't have time, when they do not like to cook, when they feel hungry (p < 0.05). These results suggest that interventions for university students include strategies to moderate fast food use by modifying behavioral beliefs, suggesting alternative menus and behavior modification techniques, increasing perception of control, and eliciting social support.

  • Fast food is popular among children and adolescents; however, its consumption has often been associated with negative impacts on nutrition and health. This study examined current fast food consumption status among middle school students and explored factors influencing fast food consumption by applying Theory of Planned Behavior. A total of 354 (52.5% boys) students were recruited from a middle school. The subjects completed a pre-tested questionnaire. The average monthly frequency of fast food consumption was 4.05 (4.25 for boys, 3.83 for girls). As expected, fast food consumption was considered to be a special event rather than part of an everyday diet, closely associated with meeting friends or celebrating, most likely with friends, special days. The Theory of Planned Behavior effectively explained fast food consumption behaviors with relatively high $R^2$ around 0.6. Multiple regression analyses showed that fast food consumption behavior was significantly related to behavioral intention (b = 0.61, P < 0.001) and perceived behavioral control (b = 0.19, P < 0.001). Further analysis showed that behavioral intention was significantly related to subjective norm (b = 0.15, P < 0.01) and perceived behavioral control (b = 0.56, P < 0.001). Attitude toward fast food consumption was not significantly associated with behavioral intention. Therefore, effective nutrition education programs on fast food consumption should include components to change the subjective norms of fast food consumption, especially among peers, and perceived behavioral control. Further studies should examine effective ways of changing subjective norms and possible alternatives to fast food consumption for students to alter perceived behavioral control.

  • The purpose of this study was to examine the impact of offering brand-name fast food at schools on student participation in school lunch. Two studies were conducted in Indiana, USA. In the first study, daily participation rate of 42 Indiana schools were compared between the days when brand-name fast food were offered and when they were not offered. The impact of brand-name fast food service on school lunch participation differed depending on the types of service offering brand-name fast food. Offering brand-name fast food solely as part of reimbursable meals or a-la-carte items was shown to induce students to the lunch option where brand-name fast food was offered. The second study examined the relationship of brand-name fast food service to monthly participation rate by analyzing secondary data of 1,282 Indiana schools using multiple regression analysis. Offering brand-name fast food was associated with monthly participation rate in school lunch only when schools offered them solely a-la-carte. Based on the results of two studies, it was concluded that offering brand-name fast food induced students from other lunch options to the options where brand-name fast food was offered on the day of service. However, increased or decreased participation in school lunch only on a few days could have not impacted average school lunch participation over a month. It is recommended that schools planning to offer brand-name fast food should make it available as part of reimbursable school lunches so that usual school lunch eaters would not be distracted to a-la-carte lines.
