The purposes of this study were to determine dimension of apparel expectations, performances and service quality of discount store and thereby, to analyze effect of apparel commodities dimension (expectations, performances, disconfirmation and satisfaction) and service dimension(service quality and satisfaction ) on repurchase intention. The subject were 363 women in the age of twenty to sixty years old who live in Seoul and the suburban of Seoul. The results of this study could be summarized as follows : It was found that discount score consumers' expectation and performance with apparel commodities were classified 2 factors of the function and expression. On the other hand, the dimensions of service quality were found to have such 4 factors as reliability, VMD, convenience, and facilities. 2. It was found that consumers' intention of repurchase of discount store were affected by such variables as disconfirmation and service quality. While less frequent users were affected by expectations and disconfirmation with apparel commodities, more frequent users were affected by such variables as disconfirmation, service quality and service satisfaction. Meanwhile, discount store users were found to be affected by disconfirmation, and off-price store users were affected by disconfirmation: and service quality. 3. More frequent users of discount store scored more on average than less frequent users in terms of expectation, performance, disconfirmation, and satisfaction with apparel commodities and intention of repurchase. On the other hand, off-price store users scored more on average than discount users in terms of expectation and performance with apparel commodities and Intention of repurchase.

In this study, we examined relationship among social class, conspicious consumption, dimensions of clothing price, and clothing buying behavior. The data were obtained by 290 female college students using questionnaire. The questionnaire were consist of four parts, dimensions of clothing price, conspicious consumption, clothing buying behavior, demographic factors. And the data were analysed with frequency, $x^2$-test, factor analysis, cluster analysis, ANOVA and Duncan test. The results were as follows. First, there was significant differences in social class and their attitude on dimensions of clothing price. Upper class consumers evaluate clothing price as Quality and dignity, on the other hand, lower class consumers perceived it as tendency for discount. Second, clothing selective standards was founded significantly different in social class. Clothing symbolic factor was more important to the upper class then lower class. Third, upper class consumers had a tendency of purchasing more clothes than lower class, and spend more money on clothing. Fourth, there was significant differences in conspicious consumption group and their attitude on dimensions of clothing price. Fifth, when conspicious consumption tendency is higher, importance of clothing price is highly perceived by college student. Sixth, Amount of clothing purchase and clothing expenditure were significantly different in conspicious consumption group. Consumers tend to buy more clothes and spend more money on clothes when they had high tendency in conspicious consumption.

This study measured and analyzed male firefighters hand sizes as well as suggested data for developing firefighting gloves with a good fit. Accordingly, body dimensions related to the hand were measured for 100 male firefighters. Twenty-three measuring items related to the hand and lower arm were selected. The firefighters' measurement data were compared to general adult male measurements from the 6th Korean Anthropometric data to analyze the hand sizes characteristics of firefighters. As a result, height, hand circumference, hand breadth, wrist circumference, elbow-wrist length, forearm-fingertip length and firefighter weight were significantly larger than adult males. A correlation analysis for 23 items was conducted to select items used as standards for setting a size when manufacturing firefighting gloves. Hand length and circumference were selected as representative hand parts for making firefighting gloves. Cross analysis between hand length and circumference were conducted to find the section showing the highest distribution ratio. As a result, the highest sections were between 19cm and 21cm for hand circumference and between 18.5cm and 19.5cm for hand length, which may be suggested as the most important ranges.

This study was performed to investigate the hand size growth of Korean adolescents boys. Subjects were between 14 and 19 years (n=352). We collected the right hand size data of 19 measurements from each subject using 3D hand scanner. The total 26 hand measurements were analyzed including seven calculated measurements. Subjects were divided into three age groups (early, middle and late). Their hand size were compared. The results showed that all hand length measurements were significantly difference among age groups. Adolescent boys hands were sharply grown at age 16 years old. The hand dimensions of middle age group were compared with twenties men (n=215). There were significant differences between two groups. The middle age adolescents' hands were shorter and thicker than twenties men. Subjects were also divided by weight and height. Weight and height was closely related to hand size. The heavier and taller subjects had the thicker hand. Their fingers were longer than others. The adolescent boys and twenties men who were taller than the twenties' average height (173.4cm) were compared. Twenties men's hands were longer and thinner than that of adolescent boys. These results imply that the male adolescent hands grow short and thick in the adolescent period. Fingers continuously grow up as a long and thin shape after adolescent period.

This study aimed to classify the hand types of adult males aged 20 to 69 years using three-dimensional measurement data from the 2020 8th Korean Anthropometric Survey, the latest measurement data from the National Institute of Standards and Technology Size Korea, and explore the characteristics of each type. Through this, I aimed to draw implications for the development of work gloves. The factors that make up an adult male's hand were categorized into hand and finger thickness factors, palm length factors, and finger length factors. Adult male hands were categorized into four types: small, thin hands and long fingers; thick, long fingers; medium, short hands and fingers; and large, thin, short fingers. The analysis showed that the younger the age, the more slender and long the hands and fingers, and as age increased, hands and fingers became shorter and thicker. Implications for the development of work gloves included the need for size segmentation based on the age of the work glove user, changes in the way glove dimensions are set based on hand length and hand circumference, and the need to segment gloves by the type of work. Hand typing in future research should be done according to occupational groups, and glove patterns should be developed for each type of work based on the results of this study.

The purpose of this study was to analyze the three-dimensional hand-related dimensions of elderly women aged 70 to 84 years and to characterize them to develop safety gloves for dementia patients. The 3D data from the 8th Human Size Survey of the National Institute of Standards and Technology, Size Korea, were analyzed using the SPSS 26.0 program. The straight thumb length was longer in elderly women aged 70-74 than in those aged 80-84. To analyze the hand type of elderly women, four factors were categorized: hand and finger horizontal factor, hand vertical factor, finger digit V thickness factor, and finger length factor. Elderly women's hand types were categorized as 'long hands and thin fingers', 'thick hands with long fingers', and 'short hands and thick little fingers'. Elderly women aged 70-74 years and 80-84 years were analyzed as having the most 'long hands and thin fingers' type, while older women aged 75-79 years were analyzed as having the most 'thick hands and long fingers' type. It is known that the fingers get thicker and the size of hands increase as age advances, but by the age 80, there is a change in the size of hands again. In future research, it would be worth expanding to other age groups to explore differences between age groups and to develop safety gloves for real-world dementia patients based on the hand types analyzed.

The practical design and construction of a Stewart Platform-based unilateral universal hand-controller is presented. It is also presented that such a design concept could be implemented by developing a technical method of determining the forward kinematics of a Stewart Platform in real time. In this work, the forward kinematics of a Stewart Platform has been determined in real time using three additional displacement sensors which eliminate the computational burden of solving the forward kinematics described in nonlinear simultaneous equations. The workspace of the Stewart Platform via inverse kinematics has been analyzed numerically and used as a design guide for the determination of the mechanism dimensions such as the sizes of the upper and base platforms and the minimum and maximum lengths of the legs. The hardware of the hand-controller has been constructed and tested to demonstrate the feasibility of the design concept.

Grip strength provides a quick and objective index of the functional integrity of the upper extremities. It is widely used as an assessment measure in physical and rehabilitation medicine. In this study, maximum voluntary grip strength of 20 college students wearing 5 different gloves were measured using Jamar hand dynamometer. The results show that maximum voluntary grip strength was generally reduced when wearing gloves as compared to bare-handed. More specifically, the grip strength was highest when wearing PVC coated glove or bare-handed and getting lowered as wrist band, rubber, leather, and cotton glove in these order. Depending on the measuring posture of grip strength, shoulder height with arm extended forward was higher than the elbow was flexed 90 degree. Moreover, subjects' demographic factors and hand dimensions were not closely related to the grip strength. It is thus recommended that the proper glove should be provided to reduce the negative consequences including dropping a tool, poorer control of a tool. lower quality work, and increased muscle fatigue and in turn to increase the user safety and satisfaction.

Objective: The aim of this study is to develop management guidelines and a procedure for an anthropometric suitability assessment of the main control room (MCR) in nuclear power plants (NPPs). Background: The condition of the MCR should be suitable for the work crews in NPPs. The suitability of the MCR depends closely on the anthropometric dimensions and ergonomic factors of the users. In particular, the MCR workspace design in NPPs is important due to the close relationship with operating crews and their work failures. Many documents and criteria have recommended that anthropometry dimensions and their studies are one of the foremost processes of the MCR design in NPPs. If these factors are not properly considered, users can feel burdened about their work and the human errors that might occur. Method: The procedure for the anthropometric suitability assessment consists of 5 phases: 1) selection of the anthropometric suitability evaluation dimensions, 2) establishment of a measurement method according to the evaluation dimensions, 3) establishment of criteria for suitability evaluation dimensions, 4) establishment of rating scale and improvement methods according to the evaluation dimensions, and 5) assessment of the final grade for evaluation dimensions. The management guidelines for an anthropometric suitability assessment were completed using 10 factors: 1) director, 2) subject, 3) evaluation period, 4) measurement method and criteria, 5) selection of equipment, 6) measurement and evaluation, 7) suitability evaluation, 8) data sharing, 9) data storage, and 10) management according to the suitability grade. Results: We propose a set of 17 anthropometric dimensions for the size, cognition/perception action/behavior, and their relationships with human errors regarding the MCR design variables through a case study. The 17 selected dimensions are height, sitting height, eye height from floor, eye height above seat, arm length, functional reach, extended functional reach, radius reach, visual field, peripheral perception, hyperopia/myopia/astigmatism, color blindness, auditory acuity, finger dexterity, hand function, body angle, and manual muscle test. We proposed criteria on these 17 anthropometric dimensions for a suitability evaluation and suggested an improvement method according to the evaluation dimensions. Conclusion: The results of this study can improve the human performance of the crew in an MCR. These management guidelines and a procedure for an anthropometric suitability assessment will be able to prevent human errors due to inadequate anthropometric dimensions. Application: The proposed set of anthropometric dimensions can be integrated into a managerial index for the anthropometric suitability of the operating crews for more careful countermeasures to human errors in NPPs.

This study is directed toward determining the number and characteristics of psychologically meaningful perceptual dimensions required for assessing the sound Ouaiity with respect to vehicle interior and/or exterior noises. and toward identifying the acoustical or psychoacoustical bases underlying the perception. By nonmetric MDS and clustring analysis of sound quality data sets on our own, of critical importance are two perceptual dimensions for which subjective verdicts can be interpreted as loudness and sharpness. The perceptual dimensions based upon similarity judgments could be accounted for 48% and 24% of the variance. each of which might be a match for the acoustic parameter "A-weighted maximum pressure level"(r= .85) and for the psychoacoustic parameter "sharpness" (r= .65), respectively. On the other hand, the perceptual dimensions based upon preference ratings could explain 66% and 10% of the variance. where the acoustic parameter "A-weighted maximum pressure leve"(r= .92) might be taken to be a best predictor, but sharpness appeared to be less suitable for the description of Preference behavior. Linked to the results, the problems of quantitative modelling of subjective sound quality evaluation and also of implementing corresponding cognitive combination rule for technical and industrial applications, say having "winner-sound qualify" according to preference criteria will be shortly in discussion.
