This paper proposes a positive experience design approach for Internet of Things (IoT) intelligent products to improve users' subjective well-being in the fields of artificial intelligence and big data. First, the authors selected six target users and taking the Xiaomi IoT intelligent products for the research objects and conducted a thorough observation on how the target users used IoT intelligent products in their own homes over two weeks via a home-visiting interview, group diary, and focus group. Second, they constructed an individual activities table for the participants' IoT intelligent product experience using a hierarchical task analysis (HTA). Third, two researchers sorted out the sub-tasks of happiness in the HTA table. Finally, the authors found the positive experience design approach of IoT intelligent products. The positive experience design approach of IoT intelligent products is proposed from focusing on the personal pleasure experience to individual life meaningful design and group social relationship design, including individual pleasure experience, personal goal realization, group needs satisfaction and the harmony of group relations. The paper uses the two design examples of an interactive kettle and a harmonious chair to further discuss the feasibility of the design approach. In the era of big data, it is helpful for designers to use this design approach to improve the users' sense of sustainable pleasure, achievement perception of their future goal realization, and the well-being of the group's social relationships.

In societies emphasizing the importance of youthful appearance, attitudes toward aging are closely related to how individuals perceive their own bodies, which can be a major determinant of psychological well-being among older adults. The purpose of this study was to examine the associations between attitudes toward aging, positive body image, and life satisfaction among older Korean adults, based on relative deprivation theory and social identity theory. Employing an online survey questionnaire, data was collected from 408 Korean aged 65 and over. The proposed research model was examined via partial least square structural equation modeling (PLS-SEM). Results revealed that higher levels of psychosocial loss were associated with lower positive body image, while higher levels of physical change and psychological growth - a good example were associated with higher positive body image. Higher levels of positive body image were associated with higher life satisfaction. Overall, positive attitudes toward aging may increase positive body image and life satisfaction among older adults, controlling for subjective financial and health status. The results of this study emphasize that we should not overlook the importance of positive body image in psychological well-being among older adults.

Purpose: The purpose of this study was to examine the effects of being aware of the physical and psychosocial environment of the school on subjective feeling of happiness in Korean middle and high school students. Methods: The data of "Health and lifestyle Survey (2019)" conducted by the National Youth Policy Institute were analyzed after receiving approval though the website. A total of 5,311 middle and high school students were included in the analysis. Descriptive statistics, t-test, one-way ANOVA, pearson correlation, and multiple regression analysis were executed using SAS 9.4. Results: The mean score of subjective feeling of happiness was 6.92±0.56 out of 10. From the univariate analysis, the more positive the perception of the physical school environment was, such as classrooms, restrooms, exercise facilities, catering facilities, health facilities, other school facilities and school uniform, the higher the subjective feeling of happiness was (p for all <.001). In addition, the psychosocial environment of the school was significantly related to the happiness of adolescents (p<.001). After controlling for gender, school level, school grade, socio-economic status, and stress, positive perception of classrooms (B=0.04, p<.001), catering facilities (B=0.01, p=.021), health facilities (B=0.08, p<.001), and the psychosocial environment of the school (B=0.18, p<.001) was significantly associated with happiness of the students. Conclusion: Positive perception of the school environment was found to increase happiness in adolescents. Therefore, efforts should be made to make classrooms, catering facilities, and health facilities a pleasant space as well as to create a school atmosphere that values health.

Block-based interframe interpolation algorithms cause severe block effect because the algorithm interpolates the skipped frame by using block based motion vector. Therefore, in this paper, we propose an algorithm that reduces the block effect in the interpolated frames. First, we propose an algorithm that obtains backward motion vector by using forward motion vector received from the transmitter. In order to predict well covered and uncovered region, backward motion vector is needed as well as forward motion vector. Second, we propose the algorithm which segments the motion boundary blocks into regions and obtains the motion vector of each region from candidates that consist of the motion vectors of neighbor blocks. This algorithm makes it possible that the moving object and the background, in spite of being in the same block, have different motion vectors from each other so that the block effect can be reduced. According to the results of simulation, the proposed algorithm is superior to conventional algorithm in subjective quality a swell as in objective quality.

The contextual subjective well-being (SWB) of context-aware system users can be very helpful in recommending relevant mental health services, especially for those who struggle with mental illness due to a metabolic syndrome or melancholia. Self-surveying measuring or auto-sensing methods have been suggested to monitor users' SWB. However, self-surveying measuring method is not inappropriate for a context-aware service due to requesting personal data in a manual and hence obtrusive manner. Moreover, auto-sensing methods still suffer from accuracy problem to be applied in mental health services. Hence, the purpose of this paper is to propose a contextual SWB estimation method to estimate the user's mental health in unobtrusive and accurate manners. This method is timely in that it acquires context data from the user's literal responses, which expose their temporal feeling. In particular, we developed a measuring method based on exposed feeling verbs and degree adverbs in chat and other text-based communications which show anger or negative feelings. Based on the proposed contextual SWB degree estimation method, we developed an idea of well-being life care recommendation. From the experiment with actual drivers, we demonstrated that the proposed method accurately estimate the user's degree of negative feelings even though it does not require a self-survey.

The Scale of Positive and Negative Experience (SPANE) is a newly developed emotional scale to measure well-being that was designed to overcome the limitations of the previous emotional scales (Diener et al., 2010). It comprises 12 items that measure positive and negative emotional experiences, including general (e.g., positive, negative) and specific (e.g., joyful, sad) items. It also reflects all levels of arousal. This study examined the factor structure and gender invariance of the Korean version of the SPANE. For this purpose, responses to the scale of a sample of 551 Korean college students (276 males and 275 females) were analyzed. The results exhibited high internal consistency reliability and construct validity for a Korean population. Furthermore, the configural, metric, and scalar invariance of the SPANE held across gender. These results suggest that the Korean version of the SPANE is a valid scale for measuring the emotional experiences of Korean students, and it is appropriate to use in future studies of gender difference in emotional well-being.

Objectives : Because of the recent well-being syndrome, concerns about smoking cessation, as well as dietary improvement and exercise, are being increased. There are various methods for smoking cessation. Among them, recently acupuncture treatment is verified through diverse attempts. This research was conducted to examine the effects of acupuncture treatment especially on juvenile smoking cessation. Methods : From April 04 to Oct 04, this study had investigated 93 middle and high school students. 5 times of acupuncture treatment were given to each participant, and the survey was executed before and after each treatment. The acupuncture was treated to the ear alternately twice a week. The evaluation was taken before the treatment after the 1st treatment, and the 5th treatment with 6 questions of amount of daily smoking, desire to smoke, taste of smoking, subjective symptoms, smoking cessation proportion, Fagerstorm Tolerance Questionaire point. Results : Regarding amount of daily smoking, the significant tendency between before and after the treatment varied, but between the 1st and the 5th treatment, there was no difference. The 1st treatment had caused desire to smoke reduction in 46 students(49.5%), but the 5th treatment didn't have much effects on desire to smoke(43 persons; 46.2%). After treatment, 37.6% had no effect in taste of smoking, while the rest of them showed various reactions. Also, there were no difference of significant tendency between the 1st and 5th treatments. In respect to the amount of smoking, 70% of them achieved smoking cessation, or reduction in smoking, but about 25% of them showed no changes. Various subjective symptoms such as lethargy, decrease of appetite, headache were shown, and especially desire to smoke was shown pervasively. Regarding Fagerstorm Tolerance Questionaire point, the average of significant tendency in point after the treatment had decreased(3.1+-2.4 to 2.1+-2.1, p<0.0001). but for those students who had tried smoking cessation less than 5 times, Fagerstorm Tolerance Questionaire point had decreased significantly, but for the others who had tried smoking cessation more than 5times, there were no difference. Conclusion : In regard to 6 questions of amount of daily smoking, desire to smoke, taste of smoking, subjective symptoms, smoking cessation proportion, Fagerstorm Tolerance Questionaire point, various conclusion is drawn. These results suggest that acupuncture treatment on juvenile may have the tendency of smoking cessation.

Purpose: This study has aimed to examine the relationship among self-esteem, Activities of Daily Living (ADL) and depression reported by hospitalized elderly patients with chronic diseases. Methods: A descriptive correlation study by means of a self-report questionnaire or face-to-face interview was used to collect data from 119 elderly patients who were hospitalized in a General Hospital from January 5 to February 25, 2010. Their levels of depression was measured using Short-Form Geriatric Depression Scale, self esteem using Jeon's, and activities of daily living using K-ADL. Results: 80.7% of the subjects experienced depression. Depression correlates with self-esteem (r=-.67) and ADL (r=.45). The influencing factors on depression were self-esteem, ADL, subjective health status, and family support satisfaction ($R^2=.57$), while self esteem in itself explained 45% of variance in depression. Conclusion: These findings indicate the importance of early detection of depression, which starts from the admission of patients and the continuing evaluation/management in daily life after discharge to ensure their well-being and quality of life. The development of program empowering self esteem, ADL and subjective health status with adequate family support during hospitalization and in daily life is indispensible.

Various characteristics of the object being lifted are known to affect the biomechanical, physiological, and psychophysical stresses. The object characteristics to be considered in the design process of lifting tasks are weight, shape, stiffness, and availability of handles and similar coupling devices. In this study, a prototype Polypropylene laminated bag with carrying handles was designed to decrease the physical stress of people who handle these bags. Physiological and psychophysical approaches as well as subjective ratings were applied to evaluate the effects of handles provided on the designed PP laminated bag. Statistical analysis showed that the VO2, heart rate, blood pressure, and Borg-RPE score for PP laminated fertilizer bag with carrying handles were significantly lower than those bags without handles. Moreover, Maximum Acceptable Lifting Endurance Time(MALET) measure, newly developed in this study, for bags with handles was significantly higher than those for bags without handles. It is thus recommended that the various types of bags and boxes be equipped with handles to reduce the musculoskeletal, physiological, psychophysical, and subjective perceived stresses.

The daylited space can improve visual comfort and occupant's well-being. However discomfort glare from the daylight is a common problem in indoor environments and in general, the window is the main glare sources. Some formulas have been proposed for predicting glare from the daylight, however, they do not consider the effect on glare of the view through a window and some studies proved that they are inadequate in real daylight situation. This research aims to identify the relationship between view and discomfort glare considering the subjective impressions. As a preliminary experiment, this paper sets up the experimental protocol to reveal relationships between views from a window and visual perception in a controlled laboratory experiment. $1.2m{\times}1.2m$ artificial window was developed and $0.9m{\times}0.9m$ view image was placed on the window. Discomfort glare and impression evaluation was carried out under four different views and one blank view as a reference condition. The results showed that the subjects evaluated discomfort glare differently with the views even under the same luminance conditions and tended to feel less glare with distance views compared to near views.
