본 연구의 목적은 PAPS-D를 활용하여 인라인스케이트 프로그램이 발달장애 학생들의 건강 체력 향상에 미치는 효과를 알아보는 것이다. 대상자는 발달장애 판정을 받은 중고등부 학생 10명으로 구성 되었고 16주 동안 주2회 총32회 수업을 하였으며, 수업시간은 매 시간 60분으로 하였다. 건강 체력 향상을 측정하기 위한 검사 도구는 2016학년도 교육과학부에서 개발한 PAPS-D 프로그램으로서 비만도 측정을 제외한 심폐기능(6분 걷기), 유연성(앉아 윗몸 앞으로 굽히기), 근 기능(윗몸 말아 올리기), 순발력(제자리 멀리뛰기)을 적용시켜 측정하였다. 통제집단과 실험집단의 상호작용 효과를 알아보기 위해 Two-way Repeated Measure ANOVA를 실시한 검사 결과는 심폐기능과 순발력에서는 유의한 차이가 있는 것으로 나타났지만, 유연성과 근 기능에서는 유의한 차이가 없는 것으로 나타났다. 4개의 변인 중 3개변인(심폐기능, 유연성, 근 기능)은 인라인스케이트 프로그램이 건강 체력 향상에 영향을 미친것으로 나타났으며, 1개의 변인(순발력)은 사전검사 보다 사후검사에서 영향을 미치지 못한 것으로 나타났다. 사전 사후 검사에서 향상된 것으로 확인된 3개 변인의 결과에 따라 결론적으로 발달장애 학생들의 인라인스케이트 프로그램 적용은 건강 체력 향상에 긍정적인 영향을 미치는 것으로 나타났다.

Different laboratory strains of Drosophila melanogaster are reported to differ considerably in their physiology, behavior, and life-histories, due to their adaptations to different laboratory conditions. Recent advances in insect aging research have highlighted the importance of protein:carbohydrate (P:C) balance as a key dietary determinant of lifespan and other components of fitness, but it remains unexplored whether P:C balance affects the fitness-related traits of D. melanogaster in a strain-specific manner. The purpose of this study was to compare the life-history consequences of six different laboratory strains of D. melanogaster (three Canton-S substrains, w1118, yw, and Oregon-R) allocated to four synthetic diets differing in P:C ratio (1:16, 1:4, 1:1, or 4:1). Five components of fitness (lifespan, fecundity, larval viability, development time, and body mass) were recorded from flies maintained at 25oC under L:D 12:12 photoperiod. All strains exhibited qualitatively similar responses to dietary P:C balance, with the increase in P:C ratio being associated with shortened lifespan and improved egg production. In all strains, fly larvae confined to P:C 1:16 suffered high mortality, retarded growth, and reduced body size. As indicated by significant diet×strain interactions for all measured fitness components, the magnitude of such diet effect varied among different laboratory strains in D. melanogaster. Possible explanations for such strain differences are discussed.

Childhood obesity causes a higher risk of obesity, premature death and disability in adulthood. In addition, obese children experience an increased risk of respiratory problems, hypertension, cardiovascular disease, insulin resistance and psychological effects. This study aimed to investigate how an exercise intervention affects health-related physical fitness and inflammatory-related blood factors in obese children after. We hypothesized that there would be positive effects on serum levels of insulin-like growth factor-1 (IGF-1), connecting peptide(C-peptide) and resistin, as well as in muscle and cardiovascular-related physical capacities, after an exercise intervention in obese children. Thirty-seven obese children haveperformed health-related fitness tests and provided blood samples for the analysis of changes in circulating biomarkers, both before and after an 8-week exercise intervention, which includes stretching, aerobic exercise, resistance exercise and sports games. The results indicate that exercise training beneficially affects body compositions, especially percentage body fat and muscle mass, without influencing to body weight and height. The results of the physical fitness tests show that muscle and cardiovascular capacity were increased in obese children in response to exercise training. Simultaneously, the exercise training decreased circulating levels of C-peptide, which equated to a “large” effect size. Although there were no significant effects on the levels of IGF-1 and resistin, they show a “small” effect size. Therefore, our findings suggest that the exercise intervention have beneficial effects on body composition and physical fitness levels in obese children, whichmight be associated with the decline in circulating C-peptide.

This study aims to contribute to the development of sports wearables. It was conducted by a convergence team of professionals in the fashion industry, kinesiology and sports studies, and computer science and engineering. The purpose of the current study was to design and develop a fabric-type fitness band for a sensor to measure acceleration during jump rope exercises. Computer science and engineering professionals developed the Arduino board and sensor, kinesiology and sports studies provided the necessary exercise protocol, and the fashion industry professionals developed the band. First, a fitness band preference survey was completed by men and women between the ages of 20 and 50. Typical uses of the band included tracking exercise amount as measured by the number of steps taken and calories burned. Strap watch closure, a single color and achromatic color, and soft and smooth touch materials were preferred as band design. Second, two fabric-type fitness bands were designed and developed. Design 1 had a 3-dimensional pocket for the sensor, bright blue color, and stretch binding around the edges and for a loop. Design 2 had a flat pocket for the sensor, achromatic color, mesh binding around the edges and two metal loops. Both designs had Velcro as a closure. Third, wear testing of both bands with the sensor were conducted of 15 women in their 20s. They wore the bands during jump rope exercises. Both bands generally satisfied the participants. The Design 2 band was slightly more satisfying than the Design 1 band.

Despite growing research interest in consumer health, well-being and beauty, little is known about factors influencing consumer purchase decisions for female fitness devices. This study focuses on Kegel exercises – exercise routines developed by Dr. Kegel to strengthen pelvic floor muscles – that are recommended by health professionals for patients experiencing health ailments such as urinary incontinence, sexual dysfunction, and dissatisfaction. Despite the benefits, women are not well aware of the role of pelvic floor muscles. The diffusion and acceptance of Kegel exercise and devices among women are likely determined by how comfortable women are about obtaining such benefits. For this reason, feminism should play an important role in shaping women’s desire to engage in Kegel exercises. Thus, this research investigates how feminism is related to Millennial women’s engagement with fitness products, particularly Kegel devices. Drawing on the literatures about sexuality, health, and marketing, we propose that feminism positively influences women’s health-related attitudes (i.e., attitudes towards fitness, fitness opinion leadership, attitude toward core strength, and desire to control sex life), which in turn positively impacts women’s fitness engagement. Fitness engagement, in turn, is expected to predict attitudes towards Kegel exercise and Kegel device purchase intentions. On the other hand, women’s attitudes toward core strength and desire to control sex life are proposed to have a direct, positive impact on attitude towards Kegel exercise. Analysis of PLS-SEM shows general support for the hypotheses. We discuss how interest in Kegel devices could, in turn, lead to positive effects on overall physical and psychological health and provide implications for marketing practitioners.

Driven by the ability to interconnect with key modern trends of healthcare and fitness, wearable devices are attracting significant level of interest from sports industry marketers. Wearable devices are the new electronic technology equipped with sensors, internet connections, processors, and operating systems and used external to the body, either attached as an accessory or embedded in clothes (Li, Wu, Gao, & Shi, 2016; Raskovic, Martin, & Jovanov, 2004; Yang, Yu, Zo, & Choi, 2016). As fully functional, self-contained electronics, wearable devices allow users to access information measured anytime and anywhere. According to ABI Research (2016), the global wearable device shipments will increase from 202 million in 2016 to more than 501 million by 2021. Specifically, market reports show that wearable fitness trackers have dominated the consumer market for wearable devices by accounting 85% of the wearable technology market in 2016 (International Data Corporation, 2016). A wrist-worn type of wearable fitness devices is the most popular but chest worn type, apparel, and other types (e.g., clip-on, ear-worn, etc.) of wearable devices are also used for fitness tracking. Wearable fitness devices analyze accumulated data of the users’ physical activity as well as provide the health and fitness status in real time. Studies on behavior change through wearable technology showed that feedback based on accurate and insightful analysis could lead long-term use of wearable devices (Fritz, Huang, Murphy, & Zimmermann, 2014; Patel, Asch, & Volpp, 2015). In this regards, smart applications linked to wearable fitness devices are widely used. As electronics IT products and services are recognized as an instance of fashion objects, many studies on the user acceptance of the products and services have focused on the importance of product design and visual attractiveness (Cyr, Head, & Ivanov, 2006; Tzou & Lu, 2007). However, little research has been done on user acceptance and behaviors of wearable fitness devices and smart applications linked to the devices focusing on the effect of the design aesthetics. Thus, the current study seeks to better understand the relationship between design aesthetics and the extended technology acceptance model (TAM) including perceived usefulness, perceived ease of use, and perceived enjoyment. In addition, this study seeks to explore the synergistic effect of visual attractiveness of the smart applications linked to them on adoption process of wearable fitness devices and the related services. The definition of fashion is “a way of behaving that is temporarily adopted by a discernible proportion of members of a social group because that chosen behavior is perceived to be socially appropriate for the time and situation (Tzou & Lu, 2009, p. 312- 313).” A fashion object has some unique characteristics including styling, aesthetics, ego gratification, etc. and is perceived to be newer, more novel, more aesthetic or even more attractive than other choices (Tzou & Lu, 2009, p. 313). As iPhone and iWatch have changed the market trends of IT products and services, it is significant that consumer electronics products with visually attractive design are more likely dominate the market and consumers’ willingness to pay is high. As a fashion technology, the most popular type of wearable fitness devices is a bracelet that users can wear on their wrist. Users wear fitness devices 24/7 to track their physical activity to gain information for healthcare and fitness practice. Specifically, wearable fitness devices track physical activity, such as workout time and intensity, steps taken, calories burned, and even sleep patterns. By quantifying users’ behaviors, the devices can educate and motivate individuals to improve their health and fitness practices (Patel et al., 2015). Considering IT products as fashion technology, many studies on user acceptance of new technology show the importance of product design and attractiveness. Researchers found that the sensory experience of information technology as well as physical electronics products determined users’ perceived usefulness, perceived ease of use, and perceived enjoyment (Childers et al., 2001; Cyr et al., 2006; van der Hdijden, 2003). However, few studies have tested the effect of aesthetics factor on the wearable fitness device adoption process. Thus, this study defines design aesthetics as an aesthetic product design expressed through shapes, colors, and materials and user interfaces of wearable fitness devices (Yang et al., 2016) and examines the effect of design aesthetics on ergonomic conceptions such as perceived usefulness and ease of use and an emotional factor, perceived enjoyment. In addition, this study focuses on the synergistic effect of design aesthetics of a smart application linked to a wearable fitness device which can motivate use of the device by providing the users more insightful information. The devices collect users’ physical activity data 24/7 and transfer the data to a smart application linked to them, either through wireless Bluetooth syncing or plugging the device into users’ smartphone or PC. Then, the application provides useful feedback by informing the users their goals, progress, and the results of activity. Visual attractiveness of a wearable device defined by Yang et al. (2016) included an aesthetic product design expressed through the wearable device as well as through mobile applications linked to the device. However, the function and presentation of a wearable device itself and a smart application linked to the device are different. Simply, the wearable device is a hardware and the smart application is a software. To fully understand the role of a wearable fitness device which is physically presented on users’ body and a smart application linked to the device which requires more information visualization, this study examines the effects of design aesthetics of a wearable fitness device and the smart application linked to the device separately on the model of wearable fitness device and service acceptance. Introduced by Davis (1989), the TAM provides a framework for understanding the likelihood that individuals will adopt a new technology. The TAM postulates that two key factors predict a technological acceptance: perceived usefulness and perceived ease of use. Defined as “the degree to which a person believes that using a particular system would enhance his or her performance (Davis, 1989, p. 320)”, perceived usefulness describes the value users believe they could find in a wearable fitness device. Meanwhile, perceived ease of use is “the degree to which a person believes that using a particular system would be free of effort (Davis, 1989, p. 320).” According to the model, perceived usefulness and perceived ease of use combined to develop behavioral intentions which in turn lead to the adoption of a technology (Davis, Warshaw, & Bagozzi, 1992, p. 660). Regarding IT products and services adoption, researchers consistently found the positive relationship between perceived usefulness and behavioral intention to adopt a new form of technology. Zaremohzzabieh et al. (2015) found a positive relationship between perceived usefulness and behavioral intention to adopt a new form of information communication technology. Lunney, Cunningham, and Eastin (2016) examined factors affecting the adoption of wearable fitness trackers found that perceived usefulness was the key factor that influenced attitude and use. Furthermore, perceived ease of use was a direct determinant of usage behavior. Researchers have agreed that perceived ease of use also a key determinant of intention to use technology (Bhattacheijee & Hikmet, 2008; Lunney et al., 2016; Tzou & Lu, 2009; van der Heijden, 2003). In addition to the original TAM model, researchers have enhanced the model by including a hedonic component of enjoyment in the adoption of IT products and services (Childers, Carr, & Carson, 2001; Cyr et al., 2006; Dabholkar & Bagozzi, 2002). Davis et al. (1992) included perceived enjoyment in TAM defining it as “the extent to which the activity of using the computer is perceived to be enjoyable in its own right, apart from any performance consequences that may be anticipated (p.1113).” Researchers found the positive relationship between perceived enjoyment and use of technology (Cyr et al., 2006; Teo, Lim, & Lai, 1999; van der Heijden, 2003).This study investigates the antecedents, moderator and consequences of wearable fitness device and service acceptance considering them as fashion technology. With empirical analysis, the results will provide interesting insights and suggestions. First, findings will show the effect of design aesthetics on ergonomic conceptions (i.e., perceived usefulness and perceived ease of use) and an emotional factor (i.e., perceived enjoyment). This indicates that IT products are not purely results of engineering advances but be recognized as an instance of fashion objects (Tzou & Lu, 2009). Second, this study focuses on the synergistic effect of design aesthetics of smart application linked to a wearable fitness device which can motivate use of the device by providing the users more insightful information. Findings in the analysis of the effect of design aesthetics of the application and its adoption will provide deeper understanding on users’ wearable fitness device adoption by indicating overall service jointly influences users’ behavior. This study will provide useful insights and evidences to sports marketing managers how consumers make choices, how manufacturers should design services as well as hardware parts in the future.

This study was conducted to analyze the effect of message frame on Exercise Interest and User Experience including Fitness App Fun, Fitness App Satisfaction, and Fitness App Use Intention in the mobile fitness app game. ‘Enjoy Your Fitness’, a fitness app game developed by Healthcare Media Research Institute, was used for this study and Repeated Measure Design and Playtest methodologies were used for the experiment. The results showed that the persuasive effect of gain messages were higher than loss messages in all factors. This results implies that exercise, as a preventive health behavior, can be promoted more effectively when messages are presented in the frame of gain message rather than loss message. Therefore, messages in the fitness app game need to be presented by emphasizing the positive outcome and benefit of exercise.

The recent fashion market failed to satisfy the needs of female customers in their 30s who are demanding a slim jacket that makes the wearer look young and slim. Accordingly, the slim-fit jackets of domestic brands targeting the women in their 30s were collected to conduct look and movement fitting evaluations based on the standard somatotype, and a slim-fit tailored jacket prototype was developed based on the present findings. This research aims to increase the satisfaction level of the slim-fit jacket customers reflecting a variety of somatotypes of women in their 30s. The research process was developing jacket patterns fully reflecting the properties in terms of extra space and design lines for different somatotypes of women in their 30s based on the jacket pattern formulated through the advanced research, and then suggesting pattern design methods for the different somatotypes. In this sense, this research attempted to identify the problems concerning the slim-fit tailored jacket fitting for different somatotypes of women in their 30s. The main aim was to suggest ways to improve the customers’ satisfaction level regarding the fit, and enable the manufacturers to produce a well-fitting jacket reflecting the peculiarities of each somatotype.

Evolutionary computation is a powerful tool for developing computer games. Back-propagation neural network(BPNN) was proved to be a universal approximator and genetic algorithm(GA) a global searcher. The game of Tic-Tac-Toe, also known as Naughts and Crosses, is often used as a test bed for testing new AI algorithms. We tried to recognize the strategic fitness of a finished Tic-Tac-Toe game when the parameters, such as a sequence of moves, its game depth and result, are provided. To implement this, we've constructed an evolutionary model using GA with back-propagation NNs(GANN). The experimental results revealed that GANN, in the very long training time, converges very slowly; however, performance of recognizing the strategic fitness does not meet we expected and, further, increase of the population size does not significantly contribute to the performance of GANN.

Commercial fitness industry is booming in Malaysia and is becoming more difficult to entice new members with the built up competition. This research investigates the needs of these commercial fitness members and the role of engagement in determining overall satisfaction with service. Scale of Service Quality for Recreational Sport (SSQRS) was used for data collection reveals that fitness members are more drawn to interaction, outcome, physical environment quality and the engagement they receive from a gym membership and not much from the programs that are offered. This study’s finding will contribute to the development of marketing strategies for the sustainable growth of the fitness industry.

The purpose of this study was to investigate the effect of combined exercise training during 12weeks on physical fitness, body composition and bone mineral density in university students. Nineteen male university students who were enrolled of 1st grade at department of physical education in Korea National University of Education were participated in this experiment. Subjects were performed combined exercise training - running, physical training using plyometrics and resistance training - of 5days per week, 70min per 1 time, during 12weeks. The measurement items were health related fitness(muscle strength, muscular endurance, cardiovascular endurance, flexibility), motor skill fitness(power, balance), body composition(% body fat, muscle mass) and bone mineral density(T-score). On the basis of the results analyzed in this study and consideration of many pre studies related it, the result were as follows. First, data analysis of 12 week combined exercise training on health related fitness, post level was revealed more significant increase than pre level at muscle strength(p<.05), muscular endurance(p<.05), cardiovascular endurance(p<.001) and flexibility(p<.05). Second, data analysis of 12 week combined exercise training on motor skill fitness, It was not revealed significant differences between the pre and the post level of the power and balance). Third, data analysis of 12 week combined exercise training on body composition, post level revealed more significant improvement than pre level at muscle mass(p<.05), but It was not revealed significant differences between the pre and the post level of the % body fat. Fourth, data analysis of 12 week combined exercise training on bone mineral density, post level revealed more significant improvement than pre level at T-score(p<.05). In conclusion, It was revealed that 12 week combined exercise training increased physical fitness, and improved body composition and bone mineral density. I hope that more studies will be followed on physical fitness, body composition and bone mineral density on various exercise types, exercise intensity, time and frequency in university students in the future.

This study was to assess the lifetime cancer and non-cancer risk on exposure to volatile organic compounds (VOCs) and formaldehyde of worker and user at public facilities in Korea. We measured the concentrations of formaldehyde and VOCs in indoor air at 160 public buildings that 5 kinds of public facilities (30 hotel, 30 fitness center, 25 gosiwon, 30 reading-room and 45 video-room) all over the country. There were estimated the human exposure dose and risks with averages of the using-time and frequency for facility users and office workers, respectively. Carcinogens (benzene and formaldehyde) were estimated the lifetime excess cancer risks (ECRs). Non-carcinogens (toluene, ethylbenzene, xylene, and styrene) were estimated the hazard quotients (HQs). HQs of four non-carcinogens did not exceed 1.0 for all subjects in all facilities. Higher HQs of toluene were observed at the reading-room. The average ECRs of formaldehyde and benzene for facility worker and user were 1×10^-4~1×10^-6 level in all facilities. The estimated ECRs for reading-room were the highest and the fitness center and gosiwon were the next higher facilities. Because lifetime ECRs of carcinogens exceeded 1×10^-4 for facility worker in the most facilities, risk management of formaldehyde and benzene in the facilities was necessary. IAQ guidelines should be determined strictly to prevent occurrence of disease caused by poor IAQ beforehand.

Since the non-metric Multidimensional scaling (nMDS), a data visualization technique, provides with insights about engineering, economic, and scientific applications, it is widely used for analyzing large non-metric multidimensional data sets. The nMDS re

Light brown apple moth, Epiphyas postvittana, is a significant horticultural pest native to Australia, and currently with a limited global distribution. However it can tolerate very heterogeneous climatic and vegetation conditions and has recently invaded California with considerable consequences for US international and domestic trade. A genetic factor that may contribute to its environmental adaptability, and consequently invasive capability, is the phosphoglucose isomerase gene (pgi). This gene codes for a key enzyme in the second step of glycolysis and for which the isozyme composition has been associated with the fitness and dispersal capacity of other moths. As a first step, to determine if this locus is variable within E. postvittana, novel primers were designed enabling access to 957 bp of the coding region across exons 4 to 11 of pgi. Exon-primed intron-crossing (EPIC) primers were then designed to compare sequences of 17 specimens across one laboratory and three wild New Zealand populations from a laditudinal range of ~39-45°S. A total of 70 segregating sites in the exons were found, including 61 synonymous and nine nonsynonymous. Introns 3 to 11 (excluding intron 10) were also sequenced for 13 individuals revealing significant length variation within and between introns and populations. The level of variation revealed here indicates that this could be a useful target gene to assess fitness factors associated with invasibility of E. postvittana.

The purpose of this study is to investigate and reveal the effects that the complex exercise training consisting of aerobic exercise and strength training(sit up, push up) that everyone can easily practice regardless of a time and a place in order to manage practically the physical strength of the aged affects the difference on their body composition and the change of physical fitness level.
