This study aims to explore driving factors of Artificial Intelligence application for city marketing strategy with perspectives of millennials and generation Z. This study proposed the following research questions: i) how perceived place branding factor, public service factor, affective factor, immersive experience factor, cognitive factor, cost benefit factor, social networking factor, and promotional value factor affect attitude toward AI application for city marketing; and ii) how attitude affect satisfaction and prospect toward AI application for city marketing? This study conducted an online survey with the assistance of a well-known research agency and applied factor and regression analysis to test hypotheses. The results found that effects of place branding, cognitive, social networking, and promotional value affect attitude significantly in the case of millennials, while effects of public service, affective, cost benefit, social networking, and promotional value affect attitude significantly in the case of generation Z. The results found that effects of attitude on satisfaction and prospect of AI showed significance. The results provide implications and different aspects for AI application of city marketing strategy with perspectives by generations, while millennials and generation Z perceived effects of promotional value as the most significant factor for AI application of city marketing strategy.

An application of the EQS (Eradi Quake System) bearings to a short period building structure and the structure earthquake responses according to the design parameters of the EQS are studied by the ICT Center case study. The features of the EQS application to seismic isolated building structures are investigated, and the design procedure to determine the yield load and the secondary stiffness of the EQS is also studied. A computational analysis is performed to confirm the applicability of the EQS to the building structure and the earthquake responses according to the design parameters. The ICT Center in Indonesia is adopted as an application case of the EQS. The application of the EQS is found to extend the fundamental period of the ICT Center. Three types of EQS with different yield loads and secondary stiffness are designed and applied in the earthquake response analyses. The analysis results show the response of the structure with respect to the design parameters and which type of EQS is suitable for the ICT Center.

Structural integrity assessment of thin-walled pipes and pipe items has become one of the major issues in the nuclear power plant. ASME Section XI Code Case N-597-2 provides a criterion for acceptance of the pipes. But the code case has several limitations for application and sometimes gives too conservative or non-conservative results. So it is necessary to understand fully the technical bases of the code case. In the code case N-597, the allowable local thicknesses of thinned straight pipes are given for three different cases. Because of the different technical base, each case gives different thickness values and sometimes gives contradictory values. In this paper attempts were made in order to propose a unified rule for the allowable local thickness and in order to remove or relax the restrictions on the application of the code case. For this purpose elastic stress analyses were made using the finite element method and the stress results were examined. Based on the obtained bending stress results, a very simple procedure was proposed to obtain the consistent allowable local thickness for the thinned straight pipes.

Thanks to the characteristic of high-rise buildings, the increase of wind speed according to the height of a building makes it possible to use high wind power resources, many countries led by some advanced nations are recently making steady and persistent effort in introducing small wind turbine systems as a step to lower electric power load in high-rise buildings. The aim of this research is to propose an optimum application process of a small wind turbine system in high-rise buildings. To achieve this goal, the case studies on the applications of high-rise and tall buildings were conducted and the best application among them was selected. On the basis of the case studies, an application process was proposed.

Over the past several years, countless patients have benefitted from the use of leeches in microsurgery. As we know, leeches are used to overcome the problem of venous congestion by creating prolonged localized bleeding uniquely characteristics of leech bite. Venous congestion, a common complication of digital replantation, often has been treated through surgical repair like arteriovenous anastomosis. The leech produces a number of important substances which contribute to the special property of the bite, including an anticoagulant, a local vasodilator and local anesthetics. The bite usually bleeds for 1 to 2 hours and under special circumstances may bleed for up to 24 hours. So venous congestion is relieved. However, leeches increase the possibility of infection through their gut content. Infection associated medical leech application is significant risk. Other risk include allergic reaction, adverse psychologic reaction and blood loss requiring transfusion. The 65 cases of medical leech application were performed between August, 1997 and May, 2000 according to an established protocol. The complication were 18 cases ; infection (13 cases), hemorrhage (2 cases), allergic reaction (1 case), psychologic problem (1 case) and hypochromic anemia (1 case). Then our study was performed on the base of indication. As a result, Aeromonas hydrophilia was cultured from gut of medical leech and Klebsiella, Staphylococcus and Pseudomonas were cultured from media. We present the clinical risk-benefit of the medical leech therapy through several cases following digital replantation.

For most of application, total system cost is first priority to Engineer. Approach for making system cost down can be to reduce cooling cost by selecting low loss item or reducing filter cost by increasing frequency. SiC Mosfet ($CoolSiC^{TM}$) can approach both of case. This paper shows market-needs and reviews each application with SiC.

Sensitivity analysis of the WRF model according to the impact of nudging (e.g., nudging techniques and application domains) was conducted during high nocturnal ozone episode to improve the prediction of the regional ozone concentration in the southeastern coastal area of the Korean peninsula. The analysis was performed by six simulation experiments: (1) without nudging (e.g., CNTL case), (2) with observation nudging (ONE case) to all domains (domain 1~4), (3) with grid nudging (GNE case) to all domains, (4)~(6) with grid nudging to domain 1, domain 1~2 and domain 1~3, respectively (GNE-1, GNE-2, GNE-3 case). The results for nudging techniques showed that the GNE case was in very good agreement with those observed during all analysis periods (e.g., daytime, nighttime, and total), as compared to the ONE case. In particular, the large effect of grid nudging on the near-surface meteorological factors (temperature, relative humidity, and wind fields) was predicted at the coastline and nearby sea during daytime. The results for application domains showed that the effects of nudging were distinguished between the meteorological factors and between the time periods. When applied grid nudging until subdomain, the improvement effects of temperature and relative humidity had differential tendencies. Temperature was increased for all time, but relative humidity was increased in daytime and was decreased in nighttime. Thus, GNE case showed better result than other cases.
