Health care services in a residential area would accelerate the aging in place. In addition, these changes would play a key role in terms of reducing healthcare costs and leading a healthy lifestyle. The purpose of this study draws the design methodology of community facilities and each dwelling with healthcare services in apartment complex, which the elderly people will enjoy a better health status. This paper presents the result focused on the welfare building in Gayang 7th apartment complex. The intention to receive healthcare services was investigated by occupants. Moreover, design requirements were drawn through in-depth interviews and the state observation to use the service. In the complex, stronger intention to serve the u-Healthcare services was shown to the pre elderly group than the elderly. Both of them had a problem to use and keep the health equipment due to the fact there is not enough space in the unit. Reporting the observation results, the upright-posture furniture attaching the healthcare equipment and the equipment storage should be prepared in the unit. In the public space, the program for these healthcare services can be divided into three parts, i.e. the health status measurement, the healthcare, and the service connected to the surrounding facilities. The health status measurement can be the basic to the health services and its function should be gradually extended. In the complex, the hybrid type with various functions could be applied owing to a new building for welfare; moreover, semi-independent user should be able to receive the home healthcare service.

The purpose of this study is to evaluate urban parks and green spaces within the public service framework by identifying priority elements. This study surveyed 455 residents from 80 dongs(neighborhoods), of 5 Gu(districts) districts in Daejeon. The results were as follows. Regarding the evaluation of urban parks as a public service, the average survey score, of all 46 questions, was distributed from 2.46 to 3.54(Likert 5 point scale). Interesting findings can be observed in that most of the survey participants gave high scores to Daejon's natural green environments and geographical traits. That is, Daejon residents perceived their urban nature spaces as a natural geographical environment rather than a public service provided by their local government. Therefore, it seems necessary for the local government, by and large, to improve urban parks and urban green space programs. The low scoring items were 'citizen's participation'(mean 2.46), 'acceptance of complaints, comments, and improvement proposals'(mean 2.54), 'citizen's respect', 'inclusive design' (for the physically challenged-mean 2.55), 'diverse programs and activities in the urban park'(mean 2.55) and 'implementation of revision proposals by citizens'(mean 2.61). These results indicate that citizen participation in planning and opinion sharing is needed to build public services that are satisfactory to users. To evaluate the park and green space from the viewpoint of public services is a useful method with a new point of view. In accordance with this study, the factor of 'supply decision maker' is a statistically meaningful variable of resident satisfaction while earlier studies on the satisfaction studies of physical environment, hardly discovered variables on 'supply decision maker', 'acceptance of resident opinions', and 'information usage'. Responding to or taking positive action according to significant factors, such as the findings of this study, can expand the role of public officials to exert a more positive influence on urban parks and green spaces.

This study analyzed the consumer awareness of cycling wear using web mining, one of the big data analysis methods. For this, the texts of postings and comments related to cycling wear from 2006 to 2017 at Naver cafe, 'people who commute by bicycle' were collected and analyzed using R packages. A total of 15,321 documents were used for data analysis. The keywords of cycling wear were extracted using a Korean morphological analyzer (KoNLP) and converted to TDM (Term Document Matrix) and co-occurrence matrix to calculate the frequency of the keywords. The most frequent keyword in cycling wear was 'tights', including the opinion that they feel embarrassed because they are too tight. When they purchase cycling wear, they appeared to consider 'price', 'size', and 'brand'. Recently 'low price' and 'cost effectiveness' have become more frequent since 2016 than before, which indicates that consumers tend to prefer practical products. Moreover, the findings showed that it is necessary to improve not only the design and wearability, but also the material functionality, such as sweat-absorbance and quick drying, and the function of pad. These showed similar results to previous studies using a questionnaire. Therefore, it is expected to be used as an objective indicator that can be reflected in product development by real-time analysis of the opinions and requirements of consumers using web mining.

This paper aims to find the optimal control gain for enhancing the convenience of electric walking frames and design a control algorithm. With the recent advances in medical technology, there has been a rapid increase in the aging population and a variety of mobile walking frames have been developed for improvement of the quality of life. However, the manual walking frames of such mobile aids don't have any electric motor which helps facilitate elderly users' walking and thus are not efficient enough for the old people of weak strength to use especially when moving on uneven surfaces such as slopes or thresholds. The types of electric walking frames have been developed to overcome such inefficiency. Electric walking frames require users' control operations for motor driving unlike manual frames. Therefore, when they are not properly handled, it causes considerable inconvenience to their users. The present study compared the electric walking frames with manual ones in terms of operational convenience and attempted to improve the user convenience of walking frames varying the control value for user convenience based on certain standards. This paper presented a haptic sensor designed to recognize the will to walk and measure the degree of convenience and proposed a control algorithm for improvement of convenience. For user convenience, this paper evaluated the relative convenience of walking frames in view of changing differences between the center of vehicle (COV) and the center of position (COP). With the employment of an electric walking frame and a new measuring method, all the processes were experimentally tested and validated.

International Exposition Yeosu Korea 2012 was held from May 12th 2012 to August 12th 2012 in New Port area of Yeosu-city, Jeollanam-do, Korea. 105 Nations and 10 international organizations participated in this mega event, and the total number of visitors amounts to 8.2 million. This study appraises the effectiveness of preparation for Yeosu Exposition. The main focus of this study is not on criticizing the problems that occurred in the transport measures. Instead, it looks at the current aspects of establishment and execution process and suggests how they can be applied differently in future transport management for international mega events held in Korea. The suggestions of this study are as follows. First, when establishing transport management plans for international mega events, the geographical features and trip resistance of the venue must be taken into consideration. Second, tasks should be distributed distinctly between the central government and the local government in order to prevent any dissension or inefficiency. Third, transport management needs to be consistent and transport guidance should be efficient in an effort to minimize visitor inconvenience. Last, transport management must be regarded as objective and rational from the outside view and the budget should follow timely based on this account.

The Ministry of Health and Welfare in Korea has enforced the oral health promotion program for elderly in Korea. There are the denture delivery program and the fluoride application-scaling program for elderly. Donggu Public Health Center in Daejeon has delivered the fluoride application-scaling program for elderly since the demonstration project in 2009. The official dental hygienists had a prior consultation with Dong-gu branch of Korean Senior Citizens Association in Daejeon. We expanded the program through government office, welfare centers, and nursing homes. The participants were satisfied with the public relations (95.2%), scaling (99.7%), fluoride application (91.5%), toothbrushing education (98.6%), and denture cleaning education (96.6%). After a medial accident with persistent bleeding, the pre-inspection survey about systemic disease and medication was reinforced. The official dental hygienists have agonized over the low participation of the low-income group and the overlap benefit with health insurance benefit of scaling. We suggested it be needed the assessment of the public oral health program to overlap with health insurance benefit.

The aim of this study is to suggest ways to capitalize on the golden period for timely response to fire and emergency victims. To implement a system to effectively capitalize on the golden period, there is a need for policy measures as well as legal and social consensus. Precedent research has relentlessly mentioned the need for and feasibility of the priority traffic system for emergency vehicles. To this end, the present study involved an analysis of pilot cases of the priority traffic signal system for emergency vehicles introduced in a city during 26 days, from April 3 to 28, 2017. Out of 58 cases registered with the local 1-1-9 fire house, the number of cases that took advantage of the priority traffic system stood at 16 in response to fire and 11 to first-aid operations. Owing to the system, on average, the response time reduced by 3 min and 50 s in case of fire and by 3 min and 30 s for first aid. There were four complaints registered owing to traffic congestion, and the number of car accidents declined to one from six over the same period in the previous year. Based on these findings, it is safe to say that the priority traffic signal system would be effective for emergency vehicles to capitalize on the golden period if issues identified during the pilot run are resolved.

The aim of this pilot survey was to investigate the presence status, usage problems, and improvement needs of the upper extremity rehabilitation equipment(: UERE) in the department of occupational therapy(: OT) of hospital setting in Korea. The authors received a questionnaires of clinicians working in a department of OT hospital setting through a social network service. Responses of 72 were analyzed in the first questionnaire, and 47 were analyzed in the second questionnaire. In the first questionnaire, the presence status of 16 UERE was confirmed to be 29.2~97.2%, and the usage experience of 9 UERE in the second questionnaire was 36.2~97.9%. In the second questionnaire, UERE's usage problems were reported discomfort in 15(31.9%) of 47 therapists, and improvement needs were 23(49%). The usage problems of the 9 UERE questioned by open-ended questionnaire were uninteresting, easily damaged, level unadjustable, direction unadjustable, and inconvenient installation. The improvement needs were classified into digitization, durability, level adjustable, adjustable function, convenience. The present pilot survey identified the presence status and usage experience of UERE in the department of OT and could be used as a basis for the development of closed-ended questionnaire on usage problems and improvement needs of UERE.

There have been increased interests in information visualization. Information visualization has been considered as a way to summarize textual data so that the users can access large amount of data more efficiently and effectively. However, many information visualization techniques stem from scientific visualization techniques, which might be difficult for the regular users to understand. More importantly, the system models used by most of the information visualization techniques do not have real world counterpart. For example, most of the users do not represent or process the textual data in terms of fisheye view or a topological map. This means that there is no affordance on the current information visualization systems from the users point of view. In this paper, we analyzed this problem by using the user interface design principles to point out what lacks in the current information visualization systems. More specifically, we have applied Nielson's Heuristic Evaluation technique to review four representative information visualization techniques. The analysis results confirmed our original hypothesis on why the current information visualization systems are not part of the mainstream information systems. Finally, we suggested to invest more efforts in improving the currently prevalent and familiar bullet list type textual information presentation method based on the usability studies and the intelligent content analysis.
