<P><B>Abstract</B></P> <P>Perovskite materials have been utilized as promising active materials for memristive devices due to their excellent properties. However, most reported perovskite-based memristive devices exhibit relatively low current ON/OFF ratios, which limits their practical applications in memory devices. In this work, memristive devices with a large memory margin were fabricated utilizing a CH<SUB>3</SUB>NH<SUB>3</SUB>PbBr<SUB>3</SUB> (MAPbBr<SUB>3</SUB>) perovskite layer. The nanocrystalline MAPbBr<SUB>3</SUB> perovskite thin films were successfully formed at low temperature by using a chlorobenzene dripping method. The MAPbBr<SUB>3</SUB> perovskite layer was employed as a resistive switching layer in memristive devices with a structure of indium-tin-oxide/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)/MAPbBr<SUB>3</SUB>/Al. The maximum ON/OFF ratio of the memristive devices based on the MAPbBr<SUB>3</SUB> perovskite was as large as 3.6ｘ10<SUP>6</SUP>.

EXPLORING THE AESTHETIC FACTOR ON WEARABLE FITNESS TECHNOLOGY ACCEPTANCE MODEL

Young-Seok Kim,,Mijung Kim 글로벌지식마케팅경영학회 2017 Global Fashion Management Conference Vol.2017 No.07

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.

Objectives : This study aimed to determine the status of thermal stimulation devices approved in Korea for medical applications over the past 10 years, and based on this, to obtain insight for future thermal treatment in Korean medical institutions. Methods : We searched the item classification list entitled Regulations on Medical Device Items and Rating by Item” from the Ministry of Food and Drug Safety Notice No. 2021-24, 2021 (Enforced March 19, 2021; www.mfds.go.kr) for individually licensed heaters using the terms heat and heating. Results : We identified 17 items of thermal stimulation product group, of which 1,308 devices were licensed by February 4, 2022, and 53.2% of them (n=696) were devices with valid permits for distribution in Korea. Among the licensed devices, heating pad systems under/overlay (electric, home use) were approved the most, but combinational stimulator (for medical use, home use; Grade 2) accounted for the highest percentage among the current valid permission. Moxibustion apparatuses were licensed separately for electrical use and non-electrical use, and occupied a low percentage of the total devices. We analyzed 307 devices that were accompanied by technical documents and found that the heat sources were wires in 145 (47.2%), infrared rays in 44 (14.3%) and ultrasonic waves in 42 (13.7%) devices. Most (83.1%) devices were used for pain relief, while other applications included beauty, cancer treatment, maintenance of infant body temperature, and healing fractures. Conclusions : Thermal stimulation devices accounted for about 0.9% of all medical devices, and among them, combinational stimulators and heating pad systems under/overlay had the most valid permits. Thermal stimulation devices using heating wires and infrared rays were the most prevalent, and most were used to relieve pain. In order to develop a range of thermal stimulation devices that can be utilized in Korean medical institutions, it is imperative that they have potential applications beyond pain management, addressing various medical purposes. To achieve this, foundational research is necessary to effectively apply diverse heat sources based on medical objectives.

스마트기기에 대한 어머니의 인식 및 양육스트레스가 영유아의 스마트기기 과몰입에 미치는 영향: 함께 사용여부의 매개효과 검증

As smart devices become more widespread, young children can easily access these devices and become proficient users. The purpose of this study is to examine the contributions of mothers’ perceptions toward smart devices and parenting stress regarding their children’s overindulgence in smart devices. Furthermore, this study explored the mediating role of parents’ co-use of smart devices among these relationships. Our data were collected from 262 Korean mothers who had a child aged less than 36 months old who have ever used smart devices. Results from a structural equation modeling analysis indicated that maternal parenting stress was directly related to children’s overindulgence. Moreover, mothers’ perceptions toward smart devices were indirectly related to children’s overindulgence through co-use. In other words, mothers who have positive perceptions of smart devices are more likely to let their child use smart devices alone, which in turn is associated with children’s overindulgence in smart devices. These findings suggest the importance of parental education about the consequences of smart devices use for young children and the roles of parents when their child uses such a devices. 본 연구는 36개월 미만의 영유아기 자녀를 둔 어머니의 스마트기기에 대한 인식, 양육스트레스, 스마트기기 함께 사용여부 및 영유아의 스마트기기 과몰입 간의 구조적 관계를 살펴보고자 하였다. 구체적으로 어머니의 스마트기기에 대한 인식 및 양육스트레스가 영유아의 스마트기기 과몰입에 미치는 직접적 영향과 스마트기기 함께 사용여부를 통해 미치는 간접적 영향을 알아보고자 하였다. 이를 위해 서울 및 대전 지역에 위치한 어린이집 18곳에 다니고 있는 36개월 미만의 자녀를 둔 262명의 어머니를 대상으로 자료를 수집하여 분석하였다. 주요 결과를 살펴보면, 어머니의 양육스트레스가 영유아의 스마트기기 과몰입에 유의한 영향을 미치는 것으로 나타났다. 또한 스마트기기 사용에 대한 어머니의 인식은 스마트기기 함께 사용여부를 매개로 영유아의 스마트기기 과몰입에 유의한 영향을 미쳤다. 즉 스마트기기 사용이 영유아의 발달에 긍정적일 것이라고 인식하는 어머니일수록 스마트기기를 자녀 혼자 사용하게 하며, 이는 영유아의 스마트기기 과몰입으로 이어졌다. 이러한 연구 결과는 스마트기기 사용이 저 연령화 되고 있는 오늘날, 영유아의 스마트기기 과몰입 예방을 위한 부모의 역할을 제시하였다는 점에서 의의가 있다.

This study aims to analyze the factors of middle-age workers’ usage of smart devices for business purpose and to propose the ways of increasing its adoption. The participants of the study were 95 middle-age insurance agents, and a survey was conducted toasure the effects of self-efficacy, conditions for using smart devices, perceived usefulness, perceived ease of use, normative influence, and the current use of smart devices on the usages of smart devises for business purpose. The results of the survey indicates that self-efficacy, perceived usefulness, perceived ease of use and the current use of smart device would explain about 60% of the intention of using smart devices for business purpose. Also, it explained that the perceived usefulness is the most influencing factor on the usage of smart devices of middle-age insurance agents. The interviews with six insurance agents who are proficient in using smart devices demonstrated that the reasons for using smart devices include its portability, the ease of responding to customers’ unexpected inquiries, the differentiating function of smart device from previous sales tools. Interestingly, the adoption of smart devices of middle-age insurance agents was influenced by their customers’ preference of using smart devices. The preference is related to the customers’ ages. Finally, providing education about the usage of smart devices for the middle-age workers, developing a performance support system via smart devices, and selecting advanced devices were suggested to increase the usage of smart devices for business purpose. 본 연구의 목적은 중장년층 보험설계사들의 업무 수행을 위한 스마트 기기 사용의도에 영향을 미치는 요인을 분석하고, 스마트 기기 활성화를 위한 방안을 모색하는 것이다. 중장년층 보험설계사 94명을 대상으로 설문조사를 통해 스마트 기기 활용에 대한 자기 효능감, 스마트 기기를 사용하는데 필요한 제반사항, 기술수용 모델에 따른 지각된 사용 용이성과 유용성, 준거집단 순응성이 스마트 기기 사용의도에 미치는 영향을 분석하였다. 분석 결과, 스마트 기기 활용에 대한 자기 효능감, 지각된 사용 용이성과 유용성, 현재 스마트 기기의 사용 빈도가 스마트 기기 사용의도에 영향을 미치는 것으로 나타났으며, 이들의 설명력은 약 60%였다. 이 중에서도 지각된 유용성이 가장 큰 영향을 미치는 것으로 조사되었다. 또한 스마트 기기를 잘 활용하고 있는 보험설계사 6명을 심층 면담한 결과, 스마트 기기를 활용하는 이유는 휴대의 편리성, 정보 검색 및 제공의 즉각성, 기존 매체와의 차별화된 속성 등이었으며, 이는 스마트 기기에 대한 지각된 유용성과 사용 용이성과도 연계된다. 또한 보험설계사들의 스마트 기기 활용 정도는 이들이 만나는 고객들의 스마트 기기에 대한 선호도에 따라 영향을 받는 것으로 나타났으며, 이는 고객의 연령과 밀접한 관련이 있는 것으로 조사되었다. 마지막으로, 중장년층 업무용 스마트 기기 활성화를 위해서는 스마트 기기의 유용성과 사용 용이성을 인식시키기 위한 사용자 대상 교육 실시, 스마트 기기용 수행지원 시스템 개발, 최신 기기의 선택과 도입 등이 제안되었다.

미용업종사자의 미용기기 사용에 대한 분쟁해결과 정책적 과제

김주리 한국중재학회 2017 중재연구 Vol.27 No.2

현대사회는 건강과 아름다움에 대한 관심이 높아지면서 미용서비스 산업의 규모가 확대되고 있다. 그러나 우리나라는 미용산업 발전에도 불구하고 현장의 낡은 규제에 의하여 외국에서 합법적으로 행하는 미용업무가 불법행위로 처벌을 받고 있는 실정이다. 이러한 문제해결을 위하여 본 논문은 미용종사자가 미용기기를 합법적으로 사용하기 위한 미용법 개정을 위하여 입법적 근거를 제시하고자 한다. 본 논문은 우리나라 미용업과 관련된 법규를 검토하고 미국, 영국, 일본의 미용기기사용에 대한 법규를 살펴보았다. 외국에서는 미용기기사용에 대하여 안전 규격기준을 마련하고 사용자격을 갖춘 자는 미용기기를 사용할 수 있다. 그러나 우리나라는 미용기기에 대한 규정과 관리에 대한 아무런 규정이 없기 때문에 미용기기 사용을 관리감독하지 못하고 있는 실정이다. 그리고 본 논문은 지난 국회에서 발의된 미용법 개선안과 정부부처의 미용법 개선과제들을 살펴보았다. 과거 수차례 미용법에 대한 개선안과 제정이 필요하다고 제안되었지만 시행되지 않았다. 미용기기에 대한 개선방안이 시행되지 못한 것은 ‘국민건강에 위해를 가할 수 있다’는 의료계 반발 때문이다. 미용기기가 의료기기로 편입되어 불법적인 사용을 양상하고 있고 미용기기의 안전한 사용과 위생적인 관리를 위한 규제를 하지 못하는 결과를 초래하고 있다. 미용산업의 선진화·세계화를 위하여 미용기기를 의료기기로 규정되어 있는 우리나라 현행법을 국제적인 환경에 동화할 수 있도록 개선되어야 한다. 의료기기로 분류되어 있는 미용기기를 피부미용실 등에서 현장 수요가 높고 인체에 대한 위해도가 낮은 품목을 우선적으로 분류하여 피부미용 품목으로 정하여 피부미용서비스의 질적 개선을 모색해야 할 필요가 있다. 그러기 위해서는 미용기기의 법률을 제정·개선하기 위한 정부의 적극적인 노력과 유사직업단체의 협조가 필요하다. 유사직업단체는 직역이기주의를 버리고 미용기기의 안전한 사용을 위하여 미용기기의 범위·규격·관리를 규정하는데 협력하여야 할 것이다. 이러한 협조가 되지 않을 시에는 중재기구를 설립하여 문제를 해결할 필요가 있다. In contemporary society interest in and consumption of beauty treatment are increasing, raising interest in health and beauty. However, beauty-related laws are becoming factors of hindrance of beauty development. Currently the Public Health Control Act plays a basic role in the beauty art business in Korea, However the contents are in discord with international laws and its definition is not clear. Therefore it is causing conflicts of different occupations and job associations which are similar to art business. Especially, because neither definitions nor policies on beauty care devices exist in the Public Health Control Act, beauty care devices using in foreign countries cannot be used in Korea due to classification as medical devices. Under this circumstance, therefore, beauty care device uses by beauty artists violate the law. The government has tried to solve these irrational regulations. Recently, the Small and Medium Business Administration announced ‘the improvement plan of small business and young founders site regulation for public economy recovery’ in a ministerial meeting on December 28, 2016. Regulations on policy preparation for skincare devices were inclusive in this announcement. It is the question whether the regulations will be executed or not. Even though beauty industrial competitiveness was presented in the 18th Presidential Council on National Competitiveness in 2009, it was not practiced. The proposal bills for beauty law improvement have been put forth several times since 2000 including an improvement plan for regulating beauty care devices. However, so far there have been no improvements. The damage on the regulation classifying beauty devices as medical devices is not only restricted to skincare. This develops beauty devices and the beauty industry which imports and exports beauty devices. When beauty devices are exported, complicated procedures are unavoidable and when beauty devices are imported, irrational problems like reregistration procedures and costs occur. The reason why an improvement plan has not gone into practice is the resistance of the dermatologists’ association. Dermatologists tend to stand positively against harming public health by saying that beauty devices used by beauty artists cause people to suffer side effects. In contrast, anyone who has a licence to use beauty devices is able to use them in foreign countries. It is not only infringement of one’s right as a beauty artist but also people’s right to receive beauty care services. With this reason, Korean’s current law under which beauty devices are ruled as medical devices should be revised with accordance to domestic surroundings. Therefore in order to advance and globalize the beauty industry, the support and cooperation of the Korean government and relevant associations is needed to legislate and revise the beauty devices laws. The relevant associations abandon regional self-centeredness and cooperate to define ranges, size and management of beauty devices for safe use. If no collaboration exists, an arbitration agency should be established to solve the problem.
