In existing factory, robot has less necessity that consider person. However, person should be considered at design and use of service robot. To service robot can be used in everyday life along with this, more functions are required. Specially, medical service robot needs function that is intelligence function. Especially, to help patient brain disease patient (cerebral hemorrhage, cerebral infarction, imbecility), gait assistance Mobile robot consider ergonomic element necessarily. In order to develop the medical support service robot, the ergonomic design should be considered. This robot ergonomic design parameters are treated in ("evelopment of Medical Support Service Robot Using Ergonomic Design" 2003, ICASS) Fig2 show this Robot. In this study, navigation algorithm of walk assistance robot is analyzed in ergonomic view. Navigation algorithm of Mobile robot can divide by two patterns. Traditional derivative method has shortcoming in dynamic environment. Reactive method is result that react excellently in dynamic environment. However, number of behavior function is limited. So hybrid navigation algorithm was proposed by the alternative way. We consider enough user specificity at navigation algorithm application of gait assistance robot.

In order to identify effective approaches for creating more viral Facebook posts, this research conducted an empirical content analysis of leading Korean brands' Facebook fan-pages (Samsung Mobile, SK Telecom, Kia Motors, and POSCO). Their distinctive visual storytelling and communication patterns were investigated as effective user engagement triggers. Through analysis of the research results, it was statistically proved that the different industrial attributes of the four brands, which are primarily characterized by their product (or service) types, affect their Facebook posting patterns by showing different engaging rates (measured by like, comment, and share metrics). In addition, the user engagement rates of the posts were influenced by their visual storytelling factors (i.e. ad objective, value scale, and visual media types). In line with these statistical findings, the distinctive visual storytelling strategies of the four brands were identified. Moreover, competitive and uncompetitive visual storytelling tactics were suggested according to the ad objectives and visual media types on Facebook.

Throughout the analysis of field data from water distribution system, valid parameters were determined that can be included in the water service and design plan. This study investigates water consumption patterns to understand the variation of water-demand structures utilizing the pattern analysis of domestic purpose water. Water use data were collected by a public water resources management firm in Korea, Kwater, for 140 houses monitored during three years. Flow meters were installed at the faucet for drinking water, the shower booth, the laundry machine, bathroom sink, toilet, and garden faucet. Data was filtered using multiple physically meaningful criteria to improve analysis credibility. Mann Kendall and Spearman's Rho tests were used to carry out the analysis. Distinct factors of water consumption patterns can be determined for both increasing and decreasing trends of water use. Throughout the data analysis, the characterization of terms was classified and analyzed by the condition of the location of water-demand. Analysis of this data provide a physical basis for the parameter configuration of a reasonable design for a domestic water demand prediction model.

Intertidal macroalgae are exposed to many abiotic stress factors, and they must regularly react to changes in their environment. We used RNA-seq to describe how Porphyra umbilicalis (Rhodophyta) changes gene expression patterns to interact with different habitats. Tissue samples were taken from a typical habitat along the open-coast of the Northwest Atlantic, as well as from a rare, atypical habitat in an estuarine tidal rapid environment. Differential gene expression analyses suggest that pathogic bacteria and viruses may be a significant factor influencing the transcriptome in the human-impacted estuarine environment, but the atypical habitat does not necessarily induce more stress in Porphyra umbilicalis growing there. We found genes related to nitrogen transport are over-expressed in tissue from the open-coastal site compared to those from the estuarine site, where environmental N levels approach hypertrophic levels. Low N levels impede growth, but high levels are toxic to cells, and we use qPCR to show this species regulates expression of a putative high-affinity $NH_4{^+}$ transporter under low and high N conditions. Differences in expression of this transporter in these habitats appear to be inherited from parent to offspring and have general implications for adaptation to habitat in other species that are capable of asexual reproduction, as well as more specific implications for this species' use in aquaculture.

This research multilaterally analyzed the frequency of use of OTT service and its effect on life satisfaction for office workers of the MZ generation using the survey data of the Korean Media Panel. Recently, the OTT service market has grown rapidly, but there is a lack of research on what changes these changes have brought to the lives of the MZ generation. In this research, the frequency of OTT service use was investigated according to the characteristics of workers in the MZ generation, and a research model was set up to test whether the frequency of use affects life satisfaction. In fact, the frequency of use varied according to the gender and age group of the MZ generation, and it was found that the frequency of use also affected life satisfaction. It has an academic contribution in that it was the first to study the relationship between media content use patterns and life satisfaction. In the future, additional research is possible not only on the frequency of use, but also on the type of OTT content and the time of use of OTT service.

The arguments exist that private health insurance(PHI) policy holders tend to use the health care services more than non-policy holders due to their little out-of-pocket spending, resulting in the adverse effects on the finances of National Health Insurance. This study aims to increase the objective understanding of the issue and to draw a direction of further research, by reviewing the articles, reports and statistics which examined the effects of purchasing PHI policies on health care utilization. Significant differences in healthcare utilization, except for the very partial increase of utilization in outpatient settings, have been not found. The similar trends of the results have existed in a few previous studies which tried to control the endogeneity of medical use and health insurance with latent variables which affect the decision on medical use and health insurance. However, we can not exclude the potential change of healthcare utilization patterns because the portion of the insured of indemnity PHI is becoming rapidly larger in the market. For further research, we should try to obtain the objective information of subjects' past medical history, health status, health related behavior, and income affecting purchase of PHI and utilization of healthcare services. And the efforts of controlling the endogeneity of medical use and health insurance with latent variables which affect the decision on medical use and health insurance, are very considerable.
