This article investigates the impact of business incubator's support service and manager's capabilities on the start-up economic performance. BI's support services consist of physical infra, management/legal service, networking service, financial service, technical service, and education/training service. The results show that most BI's support services(except education/training service) have a positive effect on the start-up economic performance. This study also analyzes the gap between the importance and the satisfaction of BI's services. The results show that the satisfaction of BI's services is much lower than the importance. It can be explained that the start-ups' expectations are not able to meet. In conclusion, BI's services have a major impact on the start-up economic performance, but actually they didn't meet the expectation of the start-ups. In the future, the quality level of BI's services and manager's capabilities needs to be improved. The improvement will have a positive effect on the survival and growth of the startups.

In rural areas, in spite of the development projects of town and houses has been performed after the New Community Movement, due to rapid industrialization and urbanization, which lasted until the 2000s from the 1980s, out-migration to the cities, changes in the industrial structure, rapid aging was carried. As a result, the gap of housing environment between urban and rural areas became more serious. The meantime, the housing problem is recognized only to the problems of the big cities, mostly urban public housing policy oriented. However, when you check the indicator of the housing environment, such as the percentage of aging housing, rural environment has become a relatively poor compared to the city. In addition, due to a decrease in income and aging of the population living in rural areas of existing infrastructure to improve the living environment is weakened. And inside of the rural areas, changes in the housing environment and polarization phenomenon is becoming increasingly serious. Therefore, in this study, there is a purpose to be presented the improvement direction for efficient implementation of house remodeling support program for underprivileged group in rural areas and requires immediate attention improvement of housing environment. Previously, House remodeling support project in rural areas was carried out at the initiative of local governments and government mainly. For this reason, it is difficult due to limited institutional, to reflect the necessary parts directly to the real life of the residents. And, the demand for improvement of housing environment need modifications to solve the inconvenience of life of residents directly in many cases. It is considered that community-based house remodeling support project is to be carried out through the participation of local residents.

Although the hotel industry in China has shown great growth both quantitatively and qualitatively, there is a lack of management of employees who represent hotels in direct contact with customers. Therefore, this study examined the social support of Chinese 4, 5 star hotel employees in Shanghai as supervisory support, coworker support, and family support, and examined whether the social support of employees improves resilience and affects their psychological well-being. In order to analyze this, we surveyed 322 employees of Shanghai 4, 5 star hotels in China. Empirical analysis showed that supervisory support and family support had a positive effect on their resilience, while coworker support did not. In addition, the resilience of hotel employees has a positive effect on their psychological well-being. This study aims to provide a better understanding of social support and resilience, and to provide effective management of human resources management.

An earthquake of $M_L$ 5.8 hit the Gyeongju area on September 12, 2016. A sequence of foreshock-mainshock-aftershock of 588 events with equal to or greater than magnitude 1.5 occurred for six months in this area. Around ninety-nine percentage (98.8%) of the total energy was released intensively within a day, and about 80% of the total events took place within a month after the Gyeongju earthquake. The epicentral distribution of aftershocks of major events ($M_L$ 5.1, 5.8, 4.5, and 3.5) were elongated in the direction of $N30^{\circ}E$. They correlate well with the focal mechanism solution. These facts support the inference that the Gyeongju earthquakes occurred on a sub-parallel subsidiary fault of the Yangsan fault zone or on the linking damage zones between Deokcheon and Yangsan fault. During the last six years before the Gyeongju earthquake, there were few events within 10-km radius from the epicenter. This seismic gap area was filled with a sequence of the Gyeongju earthquakes. The b value for aftershock of the Gyeongju earthquakes is 1.09.

Online customer reviews (i.e., electronic word-of-mouth) has gained considerable interest over the past years. However, a knowledge gap exists in explaining the mechanisms among the factors that determine the product sales in online retailing environment. To fill the gap, this study adopts a principal-agent perspective to investigate the effect of customer reviews and customer incentives on product sales in online retail stores. Two customer review factors (i.e., average review ratings and the number of reviews) and two customer incentive factors (i.e., price discounts and special shipping offers) are used to predict product sales in regression analysis. The sales ranking data collected from the video game titles at Amazon.com are used to analyze the direct effects of the four factors and the interaction effects between customer review and customer incentive factors to product sales. Result reveals that most relationships exist as hypothesized. The findings support both the direct and interaction effects of customer reviews and incentive factors on product sales. Based on the findings, discussions are provided with regard to the academic and practical contributions.

A design and control of electrostatic suspension system for flexible objects is presented. A number of electrode pairs of which the number depends on the object flexibility are positioned above the object and the voltages applied to each electrode pair are controlled, independently on the others, on the basis of the gap length. To implement the system with low cost and compactness, switched-voltage control scheme that is based on the relay feedback control is utilized. Relay feedback control method deploys only a single high-voltage power supply that can deliver a DC voltage of positive and/or negative polarity and thus high voltage amplifiers that are costly and bulky are not needed any more. It is shown that despite the inherent limit cycle property of the relay feedback based control, an excellent performance in vibration suppression is attained due to the presence of a relatively large squeeze film damping originating from the electrodes and levitated object. Employing fourteen electrode pairs, a thin aluminum plate with a thickness of 0.1 mm has been suspended at a gap length of 0.75mm.

Recently, the gap between demand and supply of natural aggregate has increased owing to the depletion of aggregate sources. Therefore, policy support is necessary for the stable supply of aggregate resources. Public and construction works experience problems when they do not receive a steady supply of aggregate. Further, instabilities in aggregate supply lead to increases in aggregate prices, and consequently construction costs. As a result, the likelihood of poor construction using low-grade aggregate increases. It is therefore crucial to put measures in place that deal with these issues. This study aims to reduce the load imposed by aggregate use on the environment by recycling soil dredged from sewage ducts to reduce the gap between supply and demand of fine aggregate. The dredged soil is assessed using an applicability test for quality characteristics and solidification with basic properties. This study aims to secure the safety of dredging soil and solidified objects through interior physical and chemical analyses and to utilize it as a base material for concrete solidification in the future.

To prevent the disincentive of labor supply under the current welfare system, we suggest the safety income system, a Korean version of negative income tax. Under the proposed system, for example, a household with four members whose annual income is less than 50 million wons will get financial support from the government. Under the safety income system, labor supply increases and so does the gross domestic product. The disposable income of low-income households increases, which alleviates the income gap among households. Analyzing the Household Income and Expenditure Survey data, we show that under the safety income system the disposable income differentials among households are reduced much more than under the current welfare system or under the universal basic income system.

A two dimensional finite element model was constructed to analyze the mechanical behavior of a five unit fred partial denture(FPD) with a 2nd premolar pier abutement either employing a rigid or nonrigid connector. Gap elements were used to model the clearance space of the nonrigid connector. All FPDs with rigid or nonrigid connectors reduced the magnitude of stress in the periodontium as compared to the control, with both normal or reduced bone support. An FPD with rigid connectors induced the smallst stresses in the periodontium. A FPD with a nonrigid connector on the mesial of the molar abutment exhibited the most undesirable mechanical stress states and deformations.
