  • Skeletal muscle fatigue is defined as a 'any reduction in the maximal capacity to generate force or power output', and is the reduction of oxygen consumption and by-product of metabolism. For the muscle fatigue therapy, low level laser has been introduced that leads the mitochondrial respiratory and attributes the muscle fatigue recovery. This study analyzed the muscle fatigue signals from electromyography(EMG) during low-level laser therapy (LLLT). Healthy subjects performed voluntary elbow flexion-extension excercise and received placebo LLLT and active LLLT using a 830 nm laser diode. Then, EMG were measured for the evaluation of muscle fatigue. The acquired EMG data were analyzed with median frequency and short time fourier transform methods. The results showed that the LLLT had a significant symptomatic relief of muscle fatigue based on the EMG frequency analysis. Therefore, the muscle fatigue analysis with EMG signals can be applied to quantitative evaluation for the monitoring of LLLT effects.

  • When purchasing products or services, consumers tend to purchase multiple value attributes through the acquisition of a product rather than physical characteristics. This study empirically analyzed the relations between consumption value, brand attitude, and purchase intention of customers purchasing fair-trade coffee, by dividing consumption values that would have significant effects on consumers' actual purchase behavior into five levels. Among the consumption value factors of customers purchasing fair-trade coffee, the functional value, social value, emotional value, and rare value all had significant effects on brand attitude and purchase intention while the influence of situational value on brand attitude and purchase intention was not verified. These finding are partially concordant with those of preceding studies, and the consumption value of consumers purchasing fair-trade coffee has positive effects on purchase behavior; therefore, it would be necessary for companies selling fair-trade products to understand consumers' specific values. Moreover, analysis of the influence of brand attitude on purchase intention of customers purchasing fair-trade coffee revealed that purchase intention increased when brand attitude was higher. These finding indicate that it is necessary to identify measures to increase purchase intention by targeting consumer groups with high brand attitude with intensive promotions.

  • This study evaluated how fresh pear cognition variables influences the purchase of primary and secondary products to promote pear consumption. The survey was performed online using 200 consumers who have consumed pears. Consumers' cognition was classified into two groups, one that was more favorable toward fresh pears and one that was less favorable. The cognition toward pear significantly affected the attitude (p<0.001) and purchase intention (p<0.001) toward fresh pear. When consumers bought fresh pear, sweetness was most important among the selection attributes to both groups, and the most common reason why consumers liked the pear analyzed by check all that apply (CATA) was also sweet taste. However, the negative group did not prefer fresh pear because of taste and texture, so those qualities should be well-controlled. In addition, cognition toward primary products influenced liking and purchase intention of processed pear products, especially beverages (p<0.001), bakeries and sweets (p<0.05). Therefore, these types of secondary products should be developed based on consumers' demands.

  • The distribution of economic activity over a mutually exclusive and exhaustive categorical industry-region matrix is modeled as a composition of two random components: the probability-like share distribution of jobs and the dynamic evolution of absolute aggregates. The former describes the individual activity location choice by comparing the predicted profitability of the current industry-region pair against that of all other alternatives based on the available information on industry-specific, region specific, or activity specific attributes. The latter describes the time evolution of macro-level aggregates using a dynamic reduced from model. With the seperation of micro choice behavior and macro dynamic aggregate constraint, the usual independence and identicality assumptions become consistent with the activity share distribution, hence multi-regional industrial migration can be represented by a set of probability evolution equations in a conservative Markovian from. We call this a Micro-Macro Composition Approach since the product of the aggregate prediction and the predicted activity share distribution gives the predicted activity distribution gives the predicted activity distribution which explicitly considers the underlying individual choice behavior. The model can be applied to interesting practical problems such as the plant location choice of multinational enterprise, the government industrial ploicy to attract international firms, and the optimal tax-transfer mix to influence activity location choice. We consider the latter as an example.

  • This study aimed at categorizing food product consumer's life types, understanding properties of each type, identifying differences in the food consumption pattern, and suggesting a strategical plan to implement market segmentation for the future food products. A demonstrative analysis revealed that consumption tendencies of the sample group in the Busan area could be categorized into four types-popular brand orientation, convenience and practicality orientation, and change and innovation oriention; an analysis of demographical differences in each group demonstrated that variabes of age and family formation showed a significant difference within a significant level. A test of differences in the significance among food consumption types in each group demonstrated that there was no signifcant difference in the number of dining-out, average cost of dining-out per person, dining-out of the week, cost of dinner, and attributes of food service selection. To the contrary, there was a significant difference in the purpose of dining-out, place of lunch, cost of lunch, menu of dinner, and food service information medium among consumption tendencies of each within a significant level.

  • The purpose of this study was to measure the estimated coefficient and marginal willingness to pay of attribute level: origin logo, origin description, traditional food, fusion food, service guarantee, and price, which influence tourist preference for restaurants. Also, the study identified the attribute which confers the highest importance to tourists. Conjoint experiment and the ordinal probit model were used for this study. A total of 210 surveys were conducted by tourists. The findings from this study were as follows. First, the effects of all attributes on tourist preference for restaurants were statistically significant. Second, tourists regarded an origin logo as the very important attribute, and were more willing to pay for the case where the menu contained origin logo. These findings suggested new marketing opportunities for restaurant managers. Although this study provides some evidence on the value of the local product brand to tourists, a similar measure has not been developed for local residents. This is an area in need of future research.

  • When people are asked to described certain textiles, they frequently refer to the expressions of its properties such as attractiveness, uniqueness, shininess, robustness, comfortability, and so on. It shows how senses play important role in it. Human employs their senses when interacting with textiles, most notably visual and tactile/ haptic to absorb its expressive properties. Yet, our sensorial experiences may amplify when interacting with those of traditional textiles, such as batik, as we can entice sensations when seeing its motifs and patterns, smelling its materials, and touching its surfaces. The multi-sensorial importance of seeing, smelling, and touching in the interaction with and experience of textiles suggests that one should address senses in a systematic way when evaluating users' perception on traditional textiles. To address this issue, the paper proposes the incorporation of Kansei Engineering (KE) approach for identifying multi-sensorial experiences on the expressive properties of traditional textiles, using batik as a case of study. KE approach address person's psychological understanding when observing things in order to analyze and study the inherent relationship between person's perceptual knowledge and objects evaluated. This paper outlines the use of KE approach in correlating sensorial perceptions when experience with traditional textiles and ultimately expose users' preferences toward them. Background of KE approach on textiles will be explored and its application for the multi-sensorial investigation of traditional textiles will be discussed.

  • The purpose of this study is to clearly understand the Korean consumer's socially responsible consumption attitude and disposition behavior through revealing by use Fishbein's Multi-Attributes Model as a conceptual frame, the relationship between the socially responsible clothing consumption attitude factors and disposition behavior pattern, and relations of demographic variables. Data were collected from the adult females residing in Seoul. Judgment Sampling were. performed twice during March of 1996 and total 549 sets of answers were used for final analysis. The result are following. First, by looking at the relationship between intrinsic side of socially responsible consumption attitude and disposition behavior, the attitude shows more economical disposition when consumers are in considerate about preservation of natural resources and clothing consumption and when consumers favor purchasing a second hand product, On the other hand, consumers' behavior shows more altruistic disposition, when they favor recycling and acquisition of second hand clothing and when not favor fashion. The result of analysis of relationship between the socially responsible clothing consumption attitude and demographic variables shows that income, age and education level relates to some intrinsic side of socially responsible clothing consumption attitude. On the other side, the analysis result shows that consumers with relatively lower education normally practice economical dispotion, while consumers with higher education level do altruistic disposition. Also, elder and married consumers tend to do more altruistic disposition.
