One of the words frequently mentioned in our society today is the smart machine. Smart machines are machines that contain smart or intelligent functions. These smart machines have recently been applied in our home environment. These are phenomena that occur as a result of smart home. In a smart home environment, smart speakers have moved away from traditional music playback functions and are now increasingly serving as interfaces to control devices, the various components of a smart home. In this study, the technology trends of domestic and foreign smart speaker market are examined, problems of current products are analyzed, and necessary core technologies are described. In the domestic smart speaker market, SKT and KT are leading the related industries, while major IT companies such as Amazon, Google and Apple are focusing on launching related products and technology development.

The purpose of this study is to identify the relationship between sexual attitude and risk behaviors, between risk behavior and sexual experiences in Korean girls high school students. The subjects for this study were 522 girls, who were samples from a target population of 63,375 11th grade students from 200 regular high schools and 70 vocational high schools in Seoul. The data were collected from June 22 to July 18, 2002. A structured questionnaire was used that included measurement of general characteristics, sexual attitudes, risk behaviors and sexual experiences. The data were processed with the SAS program, which uses descriptive statistics, t-test, and ANOVA in its an alyses. The results of this study are as follows : 1. The frequency of sexual experience is as follows ; 'holding hands' had the highest percentage, 57.4 7%, followed in order by 'arms around' 50.19%, 'act of embracing' 50.19%, 'kiss' 37.74%, 'french kiss' 30.84%, 'touch breasts' 8.62%, 'touch sexual organs' 3.26%, 'coitus' 2.30%, 'contraception' 0.77%, 'pregnancy' 0.19%, 'abortion' 0.19%, and 'prostitution' 0.19%. 2. The score of conservatives types was significantly different depending upon exposure to pornographic material and drinking. In comparison, the score of permissiveness types was significantly different depending upon exposure to pornographic material, drinking, and running away from home. But the score of pleasure seeking types was not significantly different than that of the risk behaviors types. 3. There was statistically significant difference in the sexual experience depending upon exposure to pornographic material, drinking, smoking, and running away from home. 4. In the relationship between sexual attitude types and sexual experience, there was a negative correlation between the conservatives types and sexual experiences such as 'holding hands', 'arms around', 'act of embracing', 'kiss', 'french kiss', 'touch breasts', 'touch sexual organs', and 'coitus'. There was a positive correlation between the permissiveness types and sexual experiences such as 'holding hands', 'arms around', 'act of embracing', 'kiss', 'french kiss', 'touch breasts', 'touch sexual organs', and 'coitus'. There was also a positive correlation between the pleasure-seeking types and sexual experiences such as 'touch sexual organ', 'contraceptions', 'pregnancy', and 'prostitution'. Based on the finding of this study, this society should develop a integrated program to prevent risk behaviors and sexual experiences in girls high school students.

In this paper, Ubiquitous Home Mess-Cleanup Robot(UHMR), which has a practical function of the automatic mess-cleanup, is developed. The vacuum-cleaner had made the burden of house chore lighten but the operation labour of a vacuum-cleaner had been so severe. Recently, the cleaning robot was producted to perfectly solve the cleaning labour of a house but it also was not successful because it still had a problem of mess-cleaning, which was the clean-up of big trash and the arrangement of newspapers, clothes, etc. The cleaning robot is to just vacuum dust and small trash but has no function to arrange and take away before the automatic vacuum-cleaning. For this reason, the market for the cleaning robot is not yet built up. So, we need a design method and technological algorithm of new automatic machine to solve the problem of mess-cleanup in house. It needs functions of agile automatic navigation, novel manipulation system for mess-cleanup. The automatic navigation system has to be controlled for the full scanning of living room, to recognize the absolute position and orientation of tile self, the precise tracking of the desired path, and to distinguish the mess object to clean-up from obstacle object to just avoid. The manipulate,, which is not needed in the vacuum-cleaning robot, must have the functions, how to distinguish big trash to clean from mess objects to arrange, how to grasp in according to the form of mess objects, how to move to the destination in according to mess objects and arrange them. We use the RFID system to solve the problems in this paper and propose the reading algorithm of RFID tags installed in indoor objects and environments. Then, it should be an intelligent system so that the mess cleaning task can be autonomously performed in a wide variety of situations and environments. It needs to also has the entertainment functions for the good communication between the human and UHMR. Finally, the good performance of the designed UHMR is confirmed through the results of the mess clean-up and arrangement.

Performance and flow characteristics of a small forward swept propeller fan for home refrigerators are studied experimentally. An unusual discontinuity is observed in the performance curve of the fan. Mean flow fields measured with as-hole Pitot probe reveal that the flow is axial at the high flow rate and radial at the low flow rate. The flow structure changes abruptly across the discontinuity. Unsteady flow measurements with a set of hot-wire probes indicate that near the discontinuity a single-cell stall rotates at 40% speed of the fan speed, while away from the discontinuity the flow shows periodic variation corresponding to the blade passage frequency. Phase-lock averaged flow fields measured with a triple-sensor hot-wire probe show that there appears radially inward flow over the pressure side of the blade and the outward passage flow over the tip.

The purpose of this research was to explore Korean-Chinese women's experiences of family separation. A qualitative approach was used to analyze the in-depth interviews with 14 Korean-Chinese women who lived away from their families in China. Korean-Chinese women showed the child-centered family values. The main reason of family separation was to provide children of better educational opportunities. Korean-Chinese women, their husbands, and their extended family members worked as a team to support children. Their cohesive family relationships reflected the unique sociocultural context of Korean-Chinese society. Family separation seems to be normalized for the purpose of child education. The research would contribute to understand how family values affect family life style.

The purpose of this study was to understand current food consumption phenomena in the context of Korea's consumption culture and economy. For this purpose, food consumption phenomena and the underlying meaning of consumption culture were investigated. The study indicated that current food consumption phenomena were characterized by increased eating habits away from home, consuming more fast food and processed foods, westernized diet, eager for taste, and overwhelming well-being products, which could result in environmental problems as well as malign physical and mental defects. It was argued that current food consumption phenomena had been mainly affected by the commercial food industry and consumers' cultural consideration. Finally, this paper discussed several approaches to motivate consumers' awareness and how to change their food consumption culture, and further government policy efforts.

In this study, John Burningham's picturebooks(『Come Away from The Water, Shirley』, 『Time to Get Out of The Bath, Shirley』) was analyzed using the concept of carnival among Bakhtin's conversationalism theory. In John Burningham's picturebooks, the unconscious desire for the deviation of the main character, Shirley, is transformed into an adventure in an extraordinary imaginary world, and is depicted as a festival with laughter. Through picturebooks, children are satisfied by indirectly experiencing the forbidden behavior in reality by converting it into an event in the imaginary world. This indirect experience is very important for children to naturally resolve their dissatisfaction in reality and to develop their own original inner development. This study also suggests that providing an environment where children can easily access various picturebooks at home or early childhood education institutions plays a very important role in their growth.

This article compares the psychological and behavioral profiles of adolescents on probation and high school students. A total of 253 adolescents on probation and 257 high school students completed an open-ended questionnaire developed by the present researchers and structured questionnaire that assessed moral disengagement and self-efficacy developed by Bandura (1995), delinquent behavior and academic achievement. Adolescents on probation reported that they engaged in delinquent behavior due to the fault of others and they were angry for being forced to be on probation. They are not likely to take responsibility and morally disengage from their delinquent actions. When compared to high school students, adolescents on probation are likely to report low self-efficacy, low academic grade, and less likely to feel proud of themselves. They are more likely to meet their friends in Internet and video game rooms and less likely to focus on academic achievement. Results of ANCOVA indicate that adolescents on probation have higher scores on moral disengagement, social efficacy, but lower score on efficacy for self-regulated learning. They are more likely to run away from home and have lower academic grade. The results of the discriminant analysis indicate that running away from home, social efficacy and moral disengagement are predictive of adolescents on probation and academic achievement and efficacy for self-regulated learning are predictive of high school students.
