Purpose - This study empirically analyzes the effects of food delivery service use frequency and the proportion of single-person households on the generation of MSW (Municipal Solid Waste). Additionally, the study analyzes MSW increase during the COVID-19 period. Design/methodology/approach - The study uses annual information on MSW and related characteristics of 228 Si, Gun, and Gu, which are administrative districts of Korea, from 2015 to 2020. Panel fixed effect model is employed for estimations. Findings - The study finds that food delivery and single-person household have significant effects only on recyclable and standard garbage bag MSW, respectively, not on all produce types of MSW. Additionally, it is estimated that, during the COVID-19 period, the increasing effect of food delivery is intensified while single-person households diminish its increasing effect. Lastly, the study confirms that the marginal effect on the increasing effect of MSW generation by the number of household members. Research implications or Originality - The estimated results are expected to provide useful information for the related policies. In particular, it is necessary to focus more on recyclable MSW concerning the developing delivery culture, and regarding changes in the family structure, focus more on the number of household members than single-person households.

Korea has successfully achieved a lowered fertility level owing to the strong population control policy and effective family planning program. Along with fertility decline and decreased number of children in family, average number of household members has decreased and nontraditional households such as one person household and households composed of unrelated individuals have prolifirated, even though the absolute number of them are found minimal in Korea. However in recent years several data and survey results suggest that one person households are gradually in the increasing trend. The study aimed at investigating the real state of one person households in Korea and next analyzing the proportional distribution of one person households by a few socioeconomic characteristics, thus providing basic for eatablishing far-singhted population and social welfare policy in the future. Korea has experienced high growth rate of economy through government-led development plans starting from the 1960s. During the past three decades, Korea has shifted from the agricultural state to the industrialized one. In compliance with the economic growth, urbanization and industrialization have brought about rural-to-urban migration and a great bulk of young population migrated to urban areas, who are seeking for educational and job opportunities. Korean society has also been under drastic change in every aspect of life involving norms, tradition, and attitude, etc. Therefore, in spite of the prejudice on 'living alone' still remaining, young people gradually leave parents and home, and further form nontraditional households in urban areas. Current increase in the number of one person households is partly attributable to the increase in high female educational attainment and female participation in economic activities. As the industrial structure in Korea changes from primary into secondary and tertiary industries, job opportunities for service/sales and manufacturing are opened to young female labor force in the process of industrialization. Contrary to the formation of one person households by young people, the aged single households are composed when children in family leave one by one because of marriage, education, employment. In particular, a higher proportion of aged female single households occur in rural areas due to the mortality difference by sex. Based on the data released form the 1990 Population and Housing Census and National Fertility and Family Health Survey in 1985 and 1991, the study tried to examine the state of one person households in Korea. According to Census data, the number of one person households increased to 1, 021, 000 in 1990, comprising 9.0 percent of total households. And the survey reveal that among total 11, 540 households, 8.0 percent, 923 households, are composed of one person households. Generally, the proportion of female single households is greater than that of male ones, and a big proportion of one person households is concentrated in the 25-34 age bracket in urban areas and 65 years and more in rural areas. It is shown than one person householders in urban areas have higher educational attainment with 59.2 percent high schooling and over in 1991, Job seeking proved to be the main reason for leaving home and forming one person households. The number of young female single households with higher education and economic self-reliance are found nil and the study did not allow to analyze the causal realtionship between female education and employment and one person household formation. However more research and deep analysis on the causal facors on one person household formation using statistical method are believed to be necessary.

본 논의의 출발점은 '자신을 본다'는 거울의 시선에 있다. 거울은 시각을 연장하고 자신이 가질 수 없는 상들을 제공하면서, 닮음, 재현, 반성, 실재 등에 대한 여러 의문을 제기하며 자의식을 강화하는 등 수세기 동안 그 의미는 재인식되어 왔다. 이처럼 거울을 본다는 것은 자기상의 또 다른 표면적 존재를 낳아, 거울 자체의 양면성이라는 실체와 허상 간의 모호한 간격으로 인해 지속적인 관심의 대상이다. 오늘날 거울의 반사상에 대한 과도한 열중은 더욱 심화되어 표출된다. 복잡한 이중적인 구조로 채워진 거울의 시선은 보는 자와 보이는 자의 관계로, 주체와 대상, 대상과 주체와의 불분명한 경계를 낳으며, 타인의 시선으로부터 존재하는 모든 국면들과 마주하며 교차적인 세계의 가능성을 열어준다. 더욱이 거울의 반사적 의미는 회화와 문학을 비롯한 여러 가지 미적 표현양식에 다양한 시선으로 떠오르는 모호한 수수께끼의 매체로서, 작가들에게 적지 않게 반영되며 창조적인 담론을 낳았다. 이에 본고에서는 거울의 시선이 세계의 상황 속에 서있는 이중의 영역에 반영된 불투명한 인간의 시선임을 제시하며, 보다 구체적인 접근을 위해 거울의 역사적 흐름을 전개하여 문학, 예술 작품에 투영된 일련의 사례들을 통해 닮음의 반사적 구조를 드러낼 것이다. 이 과정은 보는 자와 보이는 자의 관계, 즉 지각하는 주체와 거울에 반영된 타자의 시선임을 모색해봄으로써, 나와 세계가 상호 얽힘의 교차관계 속에서 자신의 삶이 존재하고 있음을 반추해보는 계기가 될 것이다.

In a park or street, we can see many people jogging or walking with their dogs that are chasing their masters. In this study, a pet robot that imitates dog's behavior is developed. The task of robot is to chase a person who is recognized as the master. The physical structure and the sensor system are designed for the task and environment. A three-wheel type locomotion system is designed as the robot's physical structure which can follow a person who is jogging in outdoor environment like a park. A sensor system, which can detect relative position of the master to the robot in highly dynamic and hazardous worlds, is developed. This sensor system consists of a signal transmitter which is held by the master and ultrasonic sensor array which are mounted on the robot. The transmitter emits RF (radio frequency) and ultrasonic signals simultaneously. The ultrasonic sensor array detects the signals and calculates direction and distance between the robot and the transmitter. The developed RF-ultrasonic sensor is evaluated through experiments. A purely reactive behavior-based control architecture is used for the robot. The behavior control performance of the robot is assessed in outdoor and indoor tests.
