Performances of Taekwondo fabrics were evaluated in respect of fiber component. yarn count, weave structure and wearing comfort. As a beginning step, we investigated the present situation of Taekwondo wears by questionnaire from pro and amateur Taekwondo players. Samples employed in this study were cotton/nylon blend fabric that was newly woven for this study as well as fabrics of current Taekwondo wears for sale in the market. Their fundamental properties measured were such as air permeability, water vapor transport. wickability, absorption rate, Qmax values, thermal conductivity, durability, hand value, and etc. In addition, subjective wearing sensations were evaluated using Taekwondo wears made of those fabrics. From the results of the objective measurement and the subjective wearing test, we estimated the total fitness of fabrics as a Taekwondo wear. From the questionnaire we could see that pro players and amateurs wanted highly absorbing, quick drying, and soft-tough and complained abrasive surfaces and static elasticity of current fabrics. In view of the results so far achieved, nylon blended fabrics newly woven in this study, showed better comfort-related properties from both of the objective and subjective tests. It was also represented that finer yams enhanced water absorption and touch, and fabrics with rough surface such as honeycomb weave was superior in wearing comfort as well as aesthetic appearance.

Purpose: This study was performed to evaluate the influence of field practice on subjective well-being and domains of life satisfaction in paramedic students. Methods: A self-reported questionnaire was completed by 143 paramedic students from March 5 to 31, 2016. The questionnaire consisted of subjective wellbeing, openness to experience, and domains of life satisfaction. The statistical analysis was done with SPSS/WIN 22.0. Results: The number of field practice had a lesser influence on degree of life satisfaction and positive emotions. Field practice did not influence negative emotions. Those who were open to experience tended to have higher degrees of personal satisfaction and competence irrespective of field practice. Conclusion: Openness to experience can enhance the life satisfaction and competence against the stressful conditions paramedic students experience in field practice.

Subjective evaluation has always been regarded as a branch of social science research. Hence, in scientific and especially engineering points of view, its development is always taken for granted despite the importance of its effects on the design and development decisions. In the past, at least two automotive seat survey questionnaires have been developed with high statistical validity and reliability. Nonetheless, both were not local while subjective perception very much depends on demographic background factors. It is felt that since vehicle seat comfort is an important aspect in a seat design, a local sense should be put into the survey that is used as the subjective tool. The proposed vehicle seat discomfort survey questionnaire was developed in dual languages; English and Malay. Malay language is the national language of Malaysia, where the survey was tested. Beside inputs from literatures, key informant interviews helped in establishing the appropriate terms used as survey items. Three experimental runs on two different seats by 22 paid subjects showed that the developed questionnaire is reliable and valid. Furthermore, criterion validity analysis on the survey and previously developed survey showed significant correlation at 0.01 significance level.

The study investigates the impact of the environmental protection tax, along with other factors such as attitude, subjective norm, environmental concern, and the availability of substitutes on the use of plastic bags in Vietnam. To achieve this objective, a questionnaire was prepared for data collection. The questionnaire employed a 5-point Likert scale with "completely disagree" at 1 and "completely agree" at 5. A total of 327 questionnaires were returned. However, only 291 valid responders were used in the analysis. The Cronbach's Alpha and the exploratory factor analysis were applied to test the scale reliability and discover the structure of the scales. Afterwards, we conducted the confirmatory factor analysis and the structural equation modeling to analyze collected data. The study shows that attitude is an important factor influencing the plastic bag use of consumers. Other factors that also lead to a decline in plastic bags are subjective norm and environmental concern. Meanwhile, the availability of substitutes does not affect consumers' green behavior. Moreover, the major findings of the research suggest the relationship between the environmental protection tax and the use of plastic bags is not statistically significant. In other words, tax policy may fail to change the habit of using plastic bags in Vietnam.

The purpose of this research is to access the dietary habits and weight control attitudes in college women, and to correlate them to the subjective fatigue symptoms. The research subjects are 508 women enrolled for studies in undergraduate school from freshmen to senior year in Daejeon city. The survey was conducted with self-administered questionnaire from Apr. 1st to May 1st to May 31st, 2012. In the questionnaire encompasses general characteristics, daily life style factors, dietary habits, attitude toward body type and weight control, and subjective fatigue symptoms. As a results, the affecting factors on the subjective fatigue symptoms were selected various factors such as frequency of the one food, frequency of dining out, having dinner, frequency of instant food intake, frequency of cereal, ice-cream intake, frequency of bean, soybean product intake, frequency of milk, milk product intake, consider excessive intake of sugar, consider excessive intake of salt, self-perception on body type and desire to control weight. Therefore, we can find out that their subjective fatigue symptoms are correlated to the factors in dietary habits, attitude toward body type and weight controls. It is concluded dietary habits and attitude toward body type and weight control themselves cause one's subjective fatigue symptoms, not because of each variables. So, it need efforts of having regular diets, making balanced body and controling body weights by objective ranges.

Purpose: This study aimed to investigate the correlation among perfectionism, academic resilience and subjective well-being in order to identify factors that affect subjective well-being in Korean undergraduate students. Methods: This study is a descriptive study. This study was performed on 245 students currently studying in a national university in S city. A structured questionnaire was used to collect data regarding the multidimensional perfectionism scale, the academic resilience scale, and the subjective well-being scale. Collected data were analyzed using descriptive statistics, Pearson's correlation coefficient and stepwise linear multiple regression with SPSS 25.0 for Windows. Results: Participants' scores for self-oriented perfectionism (SOP), other-oriented perfectionism (OOP), and socially prescribed perfectionism (SPP), academic resilience and subjective well-being were 64.64±12.78, 53.62±8.90, 56.98±8.96, 92.60±19.55, and 82.93±9.72, respectively. SPP showed a negative correlation with subjective well-being (r=- .27, p<.001), while academic resilience showed a positive correlation with subjective well-being (r=.20, p=.001). Satisfaction with school life, SPP, and academic resilience were identified as factors influencing subjective well-being and explained about 22% of the variance in subjective well-being. Conclusion: This study suggests that we need to identify various factors influencing subjective well-being and accordingly develop nursing interventions to improve undergraduate students' subjective well-being.

This paper describes research on mental commit robot that seeks a different direction from industrial robot, and that is not so rigidly dependent on objective measures such as accuracy and speed. The main goal of this research is to explore a new area in robotics, with an emphasis on human-robot interaction. In the previous research, we categories robots into four categories in terms of appearance. Then, we introduced a cat robot and a seal robot, and evaluated them by interviewing many people. The results showed that physical interaction improved subjective evaluation. Moreover, a priori knowledge of a subject has much influence into subjective interpretation and evaluation of mental commit robot. In this paper, 133 subjects evaluated the seal robot, Paro by questionnaires in an exhibition at the National Museum of Science and Technology in Stockholm, Sweden. This paper reports the results of statistical analysis of evaluation data.

Streetscape plays on important role in urban cities. Characteristics of streets is basically defined by the building facade, signs, plants and paving during the daytime. However at night, street receives a new appearance due to the shop light from the buildings, exterior lightings, signboards and street light, and it creates most of the image of the streets. This study aims to analyze the luminous environment and its subjective image of two different pedestrian's commercial streets. Insa-dong street and Myungdong street were chosen for the study. Horizontal illuminance and luminance on building surface, advertisement billboards and pedestrian road were measured. Thirty students were asked to rate the five scaled questionnaire on their subjective images of the streets. Statistical analysis including profile, correlation and T-test are conducted and some findings are discussed
