This study shows that consumers' attitudes and behaviors are rapidly changing due to the COVID-19 outbreak in a situation where consumption patterns are already changing due to demographic changes such as an increase in the number of single-person households and dual-income couples. To this end, the results of an online survey conducted on 500 panels of Nielsen Korea were used in this study. In particular, consumers were divided into two generation groups (Generation Z vs. Millennial) and analyzed and presented changes in consumption activities and food purchasing behaviors changed by COVID-19. As a result, the existing online distribution trend has been strengthened, and its impact has been amplified by COVID-19. These changes also resulted in different consumption behaviors depending on the degree of concern for COVID-19 by generation. Based on the results of this study, it turns consumers' behavioral changes into new opportunities, focusing on the accelerating a new 'contactless' lifestyle, which will provide managerial implications for the food industry's response strategies in relation to the theoretical significance and in practice.

In recent years, the development and market participation of major makers of next-generation eco-green vehicles has been accelerating. Consumer interest has also increased. Consumer characteristics, consumption type, characteristics of next-generation eco-friendly vehicles, and government policies on next eco-green vehicles. The results of this study are as follows. In Korea, there was no significant difference by gender, age, monthly average income, and consumer type. However, there was no significant difference in purchase intention by gender, age, and monthly income, Respectively. In the case of Japan, there was no significant difference by gender, age, monthly income, and consumer type. In Korea, on the other hand, images such as brand, color, and design have positive effects on eco-friendly vehicles. In the case of Japan, image and stability have a positive effect on consumers' purchasing behavior. Therefore, it is important for Japanese consumers to consider not only the image of purchasing an eco-friendly vehicles, but also the safety of the vehicles body, appear. In the case of Korea, the socio-environmental value-seeking type has a significant relationship with the purchasing intention. In the case of socio-environmental value-seeking type, the government's support policy such as carbon dioxide tax, direct support from the national or local governments, gasoline tax, Carbon tax and fuel related tax relief showed positive effects. In the case of Japan, the price-seeking type and the socio-environmental value-seeking type were found to have a significant relationship with the purchasing intention. Both the price-seeking type and the socio-environmental value-seeking type showed that the carbon dioxide tax, Direct support, gasoline tax, gasoline tax, and carbon tax, etc. have positive effects.

The Internet is evolving from best-effort service toward an integrated or differentiated service framework with quality-of-service (QoS) assurances that are required for new multimedia service applications. Given this increasing demand for high bandwidth Internet with QoS assurances in the coming years, an IP/MPLS-based control plane combined. with a wavelength-routed dense-wavelength division multiplexing (DWDM) optical network is seen as a very promising approach for the realization of future re-configurable transport networks. This paper proposes a differentiated lambda establishment process for QoS guarantees based on the differentiated MPLS service (DMS) model. According to the QoS characteristics of wavelength in optical links and the type of used Optical Cross-Connect (OXC) nodes in DWDM next generation optical Internet backbone network, a differentiated wavelength assignment strategy that considers QoS recovery capability is also suggested.

The purpose of this study is to observe the age differences in safety perception among babyboomer, pre-elderly, and the elderly and to seek for countermeasures to overcome the risk. The data used for this study were from the 2008 Social Survey conducted by Administration on Statistics, Korea. The data were divided into three different age groups such as babyboomer, pre-elderly, and the elderly. Results showed that overall safety level of the society, safety perception of others and oneself, current social safety level compared to 10 years ago, social safety level after 10years, awareness of safety among different social fields, and the rank among the list of factors that lead to social insecurity appeared to differ according to the three different age groups. The awareness of safety for the elderly group was not higher than babyboomer and pre-elderly groups. Age differences in safety perception reflected the times and experiences the same age cohort went through. Countermeasures for security should be developed by considering the characteristics of the generations and different age groups.

The purposes of this study were to investigate how ageism and age integration influence the perception of intergenerational conflict for each age group, and to seek alternatives to decrease intergenerational conflict. Study participants were divided into three groups based on their age: adolescence, middle age, and old age groups. For each group, the effects of ageism and age integration related variables on intergenerational conflict were examined using regression analysis. The results showed that there was no specific difference on the perception of intergenerational conflict by three different age groups; however, there were differences on influencing factors to explain the perception of intergenerational conflict. Among those factors, especially, the severity of the perception of age discrimination, which is one of ageism related variables, influenced the perception of intergenerational conflict for all age groups. That is, the more people perceived the severity of age discrimination, the more people perceived intergenerational conflict. The findings of this study are meaningful because this study revealed ageism and age integration could be causes to trigger intergenerational conflict.

This study examines the performance of and searches for improvements to the existing automatic fire detection systems installed at domestic apartment buildings as a basic study for development of intelligent fire detection systems specifically for apartments. Thus, this study aims to find out the problems in performance and maintenance of the existing fire detectors installed at apartment buildings which is the prerequisite process for development of intelligent fire detection system for that specific application. It is also found impossible to check whether or not the detectors installed at each apartment are in an operational state at normal times. This study finds that it is desirable to replace the slow-sensing heat detectors by a smoke and single smoke detectors which can detect a fire at its early stage in an effort to improve the problems of fire detectors installed at apartment buildings presently. Because we need to the independence fire detection system of apartment building.

We examine 554 state basic districts and 1832 householders in Busan metropolitan city to see whether the physical and walkable characteristics of housing influence apartment housing prices. We use two-level models modeling for a more accurate analysis. Walkable characteristics in level 2 state basic districts potentially explain 77% of the variation in housing values, with the highest impact on crime safety characteristics. Overall, our spatial multi-level analysis based on new state basic districts in Korea explained price variation better than previous studies, which considered each householder. The results provide policy opportunities for planners and citizen groups to pursue strategies that encourage the development of walkable and sustainable neighborhoods.

Most of current shooing malls on the internet do not satisfy all customers because they present arrangements of goods and suggestions uniformly and comprehensively according to the thinking of their managers. When classifying into groups according to generations, gender, income, job, hobby, etc. the propensity of purchase is showed differently and the interest and real purchasing power of the customer is different in shopping malls. This paper describes the development of customer oriented intelligent shopping mall system that is added not only statistical analysis dynamical activity of customers but also weight and construct optimal according to group of goods automatically.
