This study investigated the status of kitchen of units in elderly housing facilities and the housing needs of residents. Compared with a lot of comprehensive and alternative studies on elderly housing facilities until now, specialized studies of behavior of elderly housing life and detailed dimensional study have hardly made. Therefore we intend to examine the status of kitchen planning on representative elderly housing facilities in Korea. As the methods of this study, we executed a field study into 4 representative elderly housing facilities in Korea. We visited each 2 units out of the outstanding 4facilities and surveyed the total 8 kitchens. Then we analyzed the space planning and kitchen furniture design of them and the state of kitchen commodities, and measured the kitchen equipment. In addition, we executed interview about satisfaction, preference, use from the residents. As a result, we could find out that depending on whether residents were sewed with meal offered from the facilities or not, the pattern of usage and commodities were quite different. It is necessary to supply the simplest spaces just for preparing some refreshment and tea are suitable. And for the self-cooking residents, much larger cabinets and utility rooms are additionally needed. Safety and functional aspect were quite well designed. Washing machines are usually built-in the kitchen cabinets, and residents are satisfied with this arrangement. We hope that the supplementary study about old people habit and behavior will be a good data of kitchen planning for Korean-type elderly housing units of facilities.

Recent studies to improve reinforcement of structures have developed stiff type Polyurea by using highly polymized compound Polyurea, but the reinforcing effect of it appears to be merely good. To find the proper usage of Polyurea as structural reinforcement, stiff type Polyurea has developed by manipulating the ratio of the components that consist flexural type Polyurea and the developed stiff type Polyurea shows higher hardness and tensile capacity. The reinforcement effect evaluation of has been performed by the polyurea applied RC slab specimens, and the reinforcement effect of the combination of fiber sheet and polyurea has been tested. The results shows that the Polyurea applied specimens have significant improvement on hardness and ductility compare to those of unreinforced. Also, the specimens that stiff type Polyurea is sprayed on fiber sheet reinforcement has higher reinforcing effect than only sheet reinforced specimens. However, the specimens that and fiber sheet attached after polyurea applied on showed that the high toughness of fiber sheet restrains the ductile behavior of Polyurea due to the high ductility, thereby the specimen suffers the concentration of load, which leads the brittle fracture behavior.

The aim of this study was to examine how children's self control, mother's addiction to smart devices and parenting behavior influence the way young children used smart devices. Participants were made up of 166 preschoolers and their mothers. Descriptive analysis, Pearson's correlation coefficient, and hierarchical regression analysis were used for statistical analysis. The results were as follows: First, children in their early childhood years used smart devices once or twice a week, for ten to thirty minutes, mainly during weekends. Children in their early childhood stage started to use smart devices before reaching the age of 3, and accessed them through their parents, usually along with their siblings. Parents allowed their children to use smart devices for fun and entertainment, with only 66.3% of them setting rules. Second, the mother's tendency to be immersed in smart devices, overprotection and permission were positively correlated to young children's overusage of smart devices, whereas geniality, encouragement, setting limits, and children's self control were negatively correlated. The study also found that the mother's tendency of being immersed in smart devices was the most influential factor for their children's overusage of smart devices. The value of this study lies in providing practical suggestions for children's smart device usage and parental education programs.

Purpose - To vitalize a market or develop a new one, companies frequently release new products into the market, often by shortening the time to market, called the release period. This research aims to investigate the purchase intention behavior of consumers in terms of buying new products at the time of product release based on the release speed. Research Design, Data, and Methodology - The research reviews the influence of relative advantage, complexity, and compatibility among innovative attributes of new products, as proposed by Rogers. Moreover, it examines the moderating effect of the innovative new product attributes in terms of speed of obsolescence of old products and how that influences consumer purchase behavior. Additionally, this study tests the research hypotheses using empirical analysis. Results - The analysis demonstrated that the relative predominance (H1) and suitability (H3) of new products had a statistically significant positive influence on new product purchase intention. However, the complexity (H2) of new products had a statistically significant positive influence on new product purchase intention in contrast to its predicted sign (-). The results of the moderating effect of the old product use period were as follows. H4-1 was not supported since the difference between the path coefficients of the group with the low level old product use period and the group with the high level, represented by the relationship of relative predominance and new product purchase intention, was not statistically significant. H5-1 was also not supported since the difference between the path coefficients of the group with the low level of old product use period and the group with the high level, represented by the relationship of complexity and new product purchase intention, was not statistically significant. However, H4-2 was supported since the difference between the path coefficients of the group with the low level of old product use frequency and the group with the high level, represented by the relationship of relative advantage and new product purchase intention was statistically significant. H5-2 was not supported since the difference between the path coefficients of the group with the low level of old product use frequency and the group with the high level, represented by the relationship of complexity and new product purchase intention, was not statistically significant. H6-2 was also not supported since the difference between the path coefficients of the group with the low level of old product use frequency and the group with the high level, represented by the relationship of compatibility and new product purchase intention, was not statistically significant. Conclusion - According to the results, only H4-2 among the hypotheses on the moderating effect of the old product use period and use frequency was statistically significant. Future research should focus on carrying out a detailed review of the hypothesis on the moderating effect of the old product usage period and frequency, find the cause, and connect this to potential new research.

As the use of private cars increases along with the technological advancement in the automobile industries and their capabilities to supply, a wide range of issues are followed including the increase in traffic congestion costs, pavement damages and more. In spite of consistent effort to resolve such urban traffic problems, the modal share rate of private cars continuously increases, thus it is becoming more important to explore the ways to enable drivers to take reasonable measures, in self-motivated manner, by taking part of the transportation demand management policy rather than to rely on the strict enforcement of control policy. Considering that the urban transportation infrastructures are in much better shape than before, it is necessary to implement Mobility Management (MM) that induces reasonable usage of private cars by promoting the change in one's consciousness and behavior through communication. Hence, the research studies the factors that influence the mobility through the survey targeting the citizens of Busan on their awareness on the former transportation demand management policy, to explore the ways to motivate the citizens' involvement in reducing the use of private cars as a measure of Mobility Management.

The purpose of this study is to understand consumer awareness and preference regarding rice cakes by surveying the awareness, preference, and consumption behavior of college students regarding rice cakes, and to survey their perception and usage of rice cakes, thereby using the results as basic data to establish measures to develop Korea's rice cakes. To sum up the study's results, the survey included both male (54.5%) and female (45.5%) subjects. Those aged "20 to 23" accounted for the largest share (67.9%) of total respondents, and those majoring in "humanities and social studies" comprised the largest portion (47.8%). A majority of the respondents resided in "small and medium-sized cities", and most either lived at home or lived away from their families. A majority of the subjects received monthly allowances ranging from 200,000 to 300,000 won. In order of awareness, the most well-known type of rice cake was "injeolmi (rice cake made from glutinous rice and coated with bean flour)", followed by "songpyeon (half-moon-shaped rice cake)", "garaeddeok (bar rice cake)", and "baekseolgi (steamed white rice cake)". The women were better aware of "injeolmi", "baekseolgi", and "garaeddeok" than the men, and "soemeoriddeok" was not commonly known among either gender. In terms of preferences for rice cakes, overall, the subjects liked "injeolmi" and "songpyeon" the most. However, certain differences were found in preferences for rice cakes between the men and women. The women exhibited higher levels of preference for "injeolmi" and "songpyeon" than the men. On the other hand, the men revealed higher levels of preference for "baekseolgi", "jeolpyeon", and "garaeddeok" than the women. The most common answer to important factors for popularizing rice cakes was "a diverse assortment of rice cakes", followed by "the development of creative technologies" and "the taste of rice cakes reflecting consumer needs", in order of importance. Among the important factors to popularize rice cakes, "the development of unique packaging containers for rice cakes" (p<0.05) and "the development of proper packaging materials" (p<0.05) showed statistically significant differences. In the survey of consumption of rice cakes, the most frequent answer to the question "why do you like rice cakes? was "their tastes are good" with 146 respondents, followed by "I have been eating them for long" with 115 respondents. To the question "when do you use rice cakes", the most frequent answer was "I use them in daily life" with 133 respondents, followed by "I use them at special events" with 115 respondents. The women were found to use rice cakes frequently in daily life, whereas the men used them frequently at special events. When asked whether they had the intention to use rice cakes as a meal substitute, 100 men answered that they had no intention, whereas 96 women answered that they had the intention. When asked about the type of rice cake considered suitable for a meal substitute, the most popular answer was "injeolmi" with 108 respondents, followed by "baekseolgi" with 106 respondents.

The main purpose of this current study was to identify the structural relationships between the variables of team attachment, location-based service, and future fan behaviors by utilizing Technology Acceptance Model (TAM). Among the 10 KBO franchises, SK Wyverns and KT Wiz were qualified to have their own smart applications programs and the relevant infrastructure at their home venues. Thus, a total of 500 surveys were collected from SK Wyverns and KT Wiz games during September of 2019 and a total of 448 were used for data analysis after deleting 52 surveys due to the missing data. According to the results of a structural equation modeling, 12 positive (+) causality out of 14 hypotheses were confirmed that there must be causal relationships among the variables of location-based service at the smart stadium, TAM, fan attachment, and future fan behavior. It is hoped that this study can be contributing to the foundational developments of marketing strategies by adopting the new technological advancement in the Korean sport industry in the future.

Usage of ATM AAL2 packets becomes dominant to increase transmission efficiency of voice traffic in the backbone network. In case of voice service that uses AAL2 mechanism, if resources of network are enough, connection of new call is accepted. However, due to packets generated by the new call, transmission delay of packets from old calls can increase sharply. To control this behavior, in this paper we present an AAL2 buffer management scheme that allocates a virtual buffer to each call and after calculating its propagation delay variation(PDV), decides to drop packets coming from each call according to the PDV value. We show that this packet dropping algorithm can effectively prevent abrupt QoS degradation of old calls. To do this, we analyze AAL2 packet composition process to find a critical factor in the process that influences the end-to-end delay behavior and model the process by K-policy M/D/1 queueing system and MIN(K, Tc)-policy M/D/1 queueing system. From the mathematical model, we derive the probability generating function of AAL2 packets in the buffer and mean waiting time of packets in the AAL2 buffer. Analytical results show that the AAL2 packet dropping algorithm can provide stable AAL2 packetization delay and ATM cell generation time even if the number of voice sources increases dramatically. Finally we compare the analytical result to simulation data obtained by using the COMNET Ⅲ package.
