Online recommendation services help people search for an appropriate product among a huge assortment in stores that also minimize consumers' choice overload. People with a need for uniqueness are likely to prefer this online recommendation service based on individual needs and tastes. This study verifies the effect of consumers' choice overload and similarity avoidance in consumers' evaluation towards an online recommendation service with a focus on innovativeness and use comparability. Two-hundred consumers participated in this study and data were collected through an online survey firm. A mock retailer's webpage was created and showed six types of sneakers, which was presented as a result of product recommendation based on consumers' personal information. Data was analyzed using confirmatory factor analysis (CFA), analysis of variance (ANOVA), and regression analysis. The results show that people with a high similarity avoidance perceive an online recommendation service as an innovative and compatible service. They also perceive a high level of use compatibility for an online recommendation service, especially when it is difficult to choose a product under choice overload. Innovativeness and use compatibility of an online recommendation service increase behavioral intention. The results of this study can contribute to strategies to start online recommendation services from online retailers' websites that identify circumstances in which consumers can adopt innovative services in a positive manner.

With more emphasis on emotional communication with users in product design field, designers' clear and prompt grasp of user's emotion has become the core activity in product design research. To increase the flexibility applying emotion measurement in the process of product design, this study has used Facial Action Coding System (FACS) of behavioral emotion measurement method in product design evaluation. To select specimens, it has flexibly used the emotional product Image Map. Then this study has selected six product irritants inducing positive, negative and neutral emotions, and conducted FACS experiment with ordinary product users of 20 generations as the experimental subject, and analyzed users' emotional state in response to the irritants through their facial expressions. It also analyzes the advantages and disadvantages of FACS in the process of product design, such as "recording users' unconscious facial expressions" and puts forward some applicable schemes, such as "choosing a product stimulus with high user response". It is expected that this paper can be helpful to the flexibility of FACS as a method to predict user's emotion in advance at the trial stage of product design before launching them to the market.

The aim of this study was to determine the therapeutic effects of beauty care on negative mental health, including stress and depression. Nail care, massage care, and makeup were used as programs for beauty therapy. Qualitative research was conducted with six female participants over five-month period. After interviewing the subjects in advance, beauty care treatments were performed every week 4 weeks in the following order: nail care, massage, and makeup. The results are as follows, First, the participants perceived beauty care in the form of 4 concepts: "courtesy in social life," "investment in oneself," "self-satisfaction," and "self-care." Second, the effects of beauty therapy were categorized as "psychological effects," "confidence," "behavioral changes," "evaluation of others," and "positive social effects." Third, each subject showed different psychological effects during the process when the function of the therapy took effect through the beauty care treatment. It was confirmed that confidence levels increased as a result of treatment through the process of becoming re-aware of oneself. Positive statements from the participants included: "I want to go out," "I have become kind and positive to others," "I have become more active in a given task," and "It seems that my work ability is improving." Finally, t-test results for self-esteem, depression, and stress showed there were significant differences in self-esteem and depression. This confirmed that self-esteem increased, and depression decreased after the beauty care treatment.

In this study, the smart docent interface provided at 25 exhibition halls at domestic and foreign were compared and analyzed based on affordance. Heuristic evaluation techniques were adopted, centered on a small number of experienced people, and six research participants were selected based on Jacob Nielsen's guidelines that five to eight people per set of research can achieve sufficient results. As a result of comparative analysis of affordance, smart docent used in the Oriental showed a higher average value than smart docent used in the Western, but a lower value for sensory affordance alone. In addition, the categories were subdivided to derive the affordance values for each country, and a singularity was found that the sensory affordance of smart docents used in the United States represents the highest value compared to other countries. In conclusion, this study was able to compare the four affordances of smart docents used in domestic and foreign exhibition halls while presenting directions for future behavioral improvement, which could provide practical implication for smart docent interface design and exhibition hall service strategies.

The purpose of this study is to analyze the effects of the health information system on the productivity and behavioral aspects of health workers as well as quality of services to the visitors using the Vaccination room at the Kwon Sun Ku health center located in Suwon city as a study subject. Three survery were conducted to measure the changes in productivity and adoptation process(knowledge, attitude, activity, and satisfaction) of health workers over time during the period of 20 months. In addition, the effects of the information system on the quality of services to the visitors were also masured 7 months after the 3rd survey by comparing the quality of services between the study health center and the similar health center as a control group. The following results were obtained. First, productivity of health workers has improved over time as they became familiar with the system. Second, knowlege and activity did not significantly changed, but attitude score unexpectly decreased in the second survey. This may be due to an effect of intensive training prior to the first survery. Third, quality of services for the study center was better than other health center. While the health information system had positive effects on the productivity as well as the adoptation process, there are several limitations to establish a causal effect relationship between the two variables. For example, the system has kept modified since its development to meet the changing needs of the workers, and this may affect the productivity more than the adoptation process. Furthermore, since the study subject was only one health oenter, it lacks representativeness to generalize the study findings. Therefore, more health centers should be included in the study to solve such problems in the future.

Purpose: The aim of this study was to develop a mobile app-based musculoskeletal exercise program (AMSEP) for operating room (OR) nurses and evaluate its effects on self-efficacy, the flexibility of the shoulders, lower back, and legs, and musculoskeletal symptoms and fatigue. Methods: The AMSEP was developed based on the information-motivation-behavioral skill model. In total, 48 OR nurses were recruited at a university hospital in Korea and divided into an experimental group (n=24) and a control group (n=24), matched for career experience in the OR. The experimental group participated in the AMSEP, while the control group received a booklet regarding musculoskeletal exercise. Results: The experimental group showed significant increases in self-efficacy (t = -2.77, p = .008) and flexibility of the right shoulder (t = -4.08, p < .001), left shoulder (t = -3.28, p = .002), lower back (t = -3.75, p < .001), and legs (t = -3.96, p < .001) compared to the control group. Musculoskeletal symptoms (t = 2.75, p = .008), and fatigue (Z = -1.98, p = .048) significantly decreased in the experimental group compared to the control group. Conclusion: Our findings indicate that the AMSEP for OR nurses provided information on the prevention of musculoskeletal disorders and methods of exercise, as well as an opportunity for continued exercise performance through self-management. The AMSEP was easily accessible and effective in increasing self-efficacy and flexibility and reducing musculoskeletal symptoms and fatigue.

This study addresses the analysis of the behavioral characteristics of bridge expansion joints under wheel loading through wheel load test and the proposal of relevant wheel load specifications for expansion joints. To that goal, specimens of rail and finger expansion joints that are widely used in Korea were fabricated and subjected to static wheel load test using a real tire wheel. The wheel load distribution factor in the rail and finger expansion joints in contact with the wheel load was evaluated. The evaluation revealed that the portion of load sustained by the central rail of rail expansion joint was decreasing with larger wheel load, and that the portion of load sustained by the finger expansion joint was practically insensitive to the increase of the contact area and remained nearly constant. Since the wheel load characteristics showed large difference compared to former design specifications, it appears necessary to prepare rational specifications relative to the distribution of the wheel load contact pressure for the design of expansion joints.
