  • Purpose: This study tries to comprehend older adults' perspectives of community supports and health services in a South Korean city and identify important sociodemographic and health characteristics that affect their perspectives. Methods: 166 older adults were involved in this cross-sectional study. Questions on background characteristics and community supports and health services criteria (categorized as service accessibility, offer of services, voluntary support, or emergency care planning) based upon the WHO's Age-Friendly Cities Guide were used. The data were analyzed using paired and independent t-tests, one-way ANOVA, and hierarchical multiple regression analyses. Results: emergency care planning was rated as the most important by the participants (mean age=76.24 years, 22.9% male), while its current level of performance was lowly appraised (p<.001). The rated importance for each category differed based on individual characteristics. Depression (p=.016), older age (p=.012), and restricted network type (p=.039) were significantly related to ascribing a higher degree of importance to community services. Conclusion: Community initiatives are warranted to optimize emergency care for older adults. This planning must be based on the unique characteristics of older adults in coordination with supportive resources. In addition, comprehensive assessments are warranted before implementing action plans to ensure that the multi-dimensional problems of older adults are incorporated.

  • PURPOSE. This study aims to evaluate the accuracy of different shade selection techniques and determine the matching success of crown restorations fabricated using digital shade selection techniques. MATERIALS AND METHODS. Teeth numbers 11 and 21 were prepared on a typodont model. For the #11 tooth, six different crowns were fabricated with randomly selected colors and set as the target crowns. The following four test groups were established: Group C, where the visual shade selection was performed using the Vita 3D Master Shade Guide and the group served as the control; Group Ph, where the shade selection was performed under the guidance of dental photography; Group S, where the shade selection was performed by measuring the target tooth color using a spectrophotometer; and Group I, where the shade selection was performed by scanning the test specimens and target crowns using an intraoral scanner. Based on the test groups, 24 crowns were fabricated using different shade selection techniques. The ΔE values were calculated according to the CIEDE2000 (2:1:1) formula. The collected data were analyzed by means of a one-way analysis of variance. RESULTS. For the four test groups (Groups C, Ph, S, and I), the following mean ΔE values were obtained: 2.74, 3.62, 2.13, and 3.5, respectively. No significant differences were found among the test groups. CONCLUSION. Although there was no statistically significant difference among the shade selection techniques, Group S had relatively lower ΔE values. Moreover, according to the test results, the spectrophotometer shade selection technique may provide more successful clinical results.

  • This study analyzed some of nursing homes in various domestic and foreign regions in order to find solutions to reduce suicidal incidents from the loneliness. To analyze community space of nursing homes, elderly community is analyzed into three categories based on their characteristics (morphological characteristics, Social characteristics, Environmental characteristics). With those three characteristics above, architectural spaces are analyzed the relation with them. Elderly nursing homes are divided with living, nursing, management, and public spaces. The space of elderly nursing homes (classification of function)-elderly community (classification of elderly characteristics) is approached in an architectural way related to the space of elderly nursing homes and elderly characteristics. Through some case studies, specific space relation of elderly nursing homes and elderly community is analyzed. Also, with the building analysis for summary, plans, wards(hospital rooms), cafeteria, program rooms and alley, some of general information and elderly community space is understood. In this study, there will be an analysis of relation of elderly community(morphological, social, environmental characteristics) which is separated into some spaces of elderly nursing homes(living, nursing, public spaces and facilities) written above. Furthermore, if people can recognize the importance of community space for elderly facilities, there will be a new guide line for that which can have a play on catalyst.

  • In this study, we showed understanding and production ability of the interface about internet, operating system, contents, and devices. This study aimed to make a list of 18 items in 4 areas for basic knowledge of UI/UX, establishment of design research, design concept, and design production for 22 sophomore, junior and senior students in IT departments, and the results of understanding were divided into three groups of excellent, normal, and insufficient, and evaluated. It was found that excellent was 18.39%, average was 38.52% and insufficient was 43.07%. Therefore, 18.39% of the students understood UI/UX, and 81.61% of students did not understand UI/UX well. In particular, in the comparison analysis of four areas, the design research area was 44 points, the design content area was 29 points, and the design production area was 11 points which was found to be the lowest. Next, the 10 evaluation items in the mobile UI/UX build guide evaluation were evaluated in the same way as the UI/UX understanding, and the excellent score was 3 points, the average score was 73.3 points, and the poor score was 155 points. The UI/UX build guides showed worse evaluation than UI/UX understanding. Therefore, to cultivate UI/UX understanding and content production ability, UI/UX experts should be fostered with professional course organization and systematic curriculum.

  • In today's digital non-linear global business environment, innovation initiatives are influenced by inter-organizational, political, economic, environmental, technological systems, as well as by decisions made individually by key actors in these systems. Network-based structures emerge from social linkages and collaborations among various actors, creating innovation ecosystems, complex adaptive systems in which entities co-create value. A shared vision of value co-creation allows people operating individually to arrive together at the same future. Yet, relationships are difficult to see, continually changing and challenging to manage. The Innovation Ecosystem Transformation Framework construct includes three core components to make innovation relationships visible and articulate networks of relational capital for the wellbeing, sustainability and business success of innovation ecosystems: data-driven visualizations, storytelling and shared vision. Access to data facilitates building evidence-based visualizations using relational data. This has dramatically altered the way leaders can use data-driven analysis to develop insights and provide ongoing feedback needed to orchestrate relational capital and build shared vision for high quality decisions about innovation. Enabled by a shared vision, relational capital can guide decisions that catalyze, support and sustain an ecosystemic milieu conducive to innovation for business growth.

  • Recently, demands for the development of compact, lightweight power supplies with higher power density and higher efficiency have been increased. Since Piezoelectric Transformer (PT) was emerged in device and material industry, it has been suggested as a viable alternative to the magnetic transformer in some applications. PT has some advantages such as low profile and mechanical energy transfer with little electromagnetic interface (EMI). Also, PT can provide high voltage stepping ratio with good isolation and requires no copper windings saving copper usage especially for large voltage conversion differences. Conventional control of PT converter has mainly two-way. One is the pulse frequency modulation (PFM) control method and the other is the pulse width modulation (PWM) control with frequency fixed method. It is known that the maximum PT efficiency can be obtained when it operates near the resonant frequency of the PT. And, also PT's resonant frequency moves according to the load condition. Therefore, selection of PT converter control method is very difficult. This paper analyzes general piezo-electric converter modeling and proposes a guide-line to selection of control method and stabilization control.

  • There are three natural conservation systems that UNESCO assigns: World Heritage, Biosphere Reserve and Geopark. Geopark is one of three preservation zones that UNESCO conducts. In this paper I will explain the meaning of a Geopark as well as suggest that one should be set up in Korea. Geotourism is one important aspect of Geopark. Geopark's main purpose is not only for sightseeing but also conservation and understanding the value of nature through geological and geographical features. I have analyzed the local guide's interpretations from a Hongdo Island cruise tour and suggested new way of interpretation for the tour with the concept of Korean Geotourism in mind.
