본 연구의 목적은 한국 노인의 생활시간 사용을 유형화하여 유형별 영향요인과 차이를 확인하고 각 유형이 생활만족도에 미치는 영향을 파악하는 것이다. 이를 위해 국민노후보장패널 6차 자료를 활용하여 65세 이상 노인 3,963명을 대상으로 잠재프로파일 분석을 실시하였다. 생활시간 유형 분류 결과 한국 노인의 생활시간 활용은 기초생활유지형(16%), 여가자유중심형(26%), 사회활동형(58%)의 3가지로 유형화 되었다. 각 유형별 영향요인 파악을 위한 다항 로지스틱 회귀분석 결과 기초생활유지형 대비 여가자유중심형의 주요 영향요인은 배우자의 유무(p<.01), 심리적 건강상태(p<.001)로 나타났고, 사회활동형의 주요 영향요인은 연령(p<.05), 경제적 활동(p<.001), 만성질환(p<.001)으로 나타났다. 생활만족도에 영향을 미치는 요인을 종합적으로 분석한 결과, 기초생활유지형에 비해 여가자유중심형과 사회활동형의 생활만족도가 더 높게 나타났다. 연구결과를 바탕으로 기초생활유지형으로 시간을 활용하고 있는 노인의 시간사용 유형 변화를 추구하여 노년기 생활만족도를 제고하기 위한 실천적 정책적 제언을 제시하였다.

The significant aim of this research has always been to evaluate the mechanism for efficient and inherently aware usage of vitality in-home devices, thus improving the information of smart metering systems with regard to the usage of selected homes and the time of use. Advances in information processing are commonly used to quantify gigantic building activity data steps to boost the activity efficiency of the building energy systems. Here, some smart data mining models are offered to measure, and predict the time series for energy in order to expose different ephemeral principles for using energy. Such considerations illustrate the use of machines in relation to time, such as day hour, time of day, week, month and year relationships within a family unit, which are key components in gathering and separating the effect of consumers behaviors in the use of energy and their pattern of energy prediction. It is necessary to determine the multiple relations through the usage of different appliances from simultaneous information flows. In comparison, specific relations among interval-based instances where multiple appliances use continue for certain duration are difficult to determine. In order to resolve these difficulties, an unsupervised energy time-series data clustering and a frequent pattern mining study as well as a deep learning technique for estimating energy use were presented. A broad test using true data sets that are rich in smart meter data were conducted. The exact results of the appliance designs that were recognized by the proposed model were filled out by Deep Convolutional Neural Networks (CNN) and Recurrent Neural Networks (LSTM and GRU) at each stage, with consolidated accuracy of 94.79%, 97.99%, 99.61%, for 25%, 50%, and 75%, respectively.

본 연구는 "2014 생활시간조사" 데이터를 이용하여 부부의 시간배분 결정요인에 대하여 분석하였다. 분석 결과, 대체로 남편의 육아 및 가사시간은 아내에 비하여 매우 적은 것으로 나타났으며, 아내의 임금이 높고, 어린 자녀가 있을 경우 남편의 육아 및 가사시간이 증가하였다. 아내 시간배분의 경우는 주로 배우자(남편)의 임금에 많은 영향을 받는 것으로 나타났는데, 남편의 임금이 증가할수록 아내의 노동시간은 감소하며, 가사시간은 증가하는 것으로 나타났다. 그러나 육아시간은 아내와 남편 모두의 임금에 영향을 받지 않는 것으로 나타났다. 반면 아내의 임금이 증가할 경우에 남편의 육아 가사시간이 같이 증가하는 경향이 있었다. 시간배분의 상관관계에서 아내의 노동시간과 남편의 가사시간은 보완관계에 있었으나, 아내와 남편의 가사시간은 대체관계에 있는 것으로 나타났다. 이것은 곧 아내가 일을 많이 하여 생긴 가사일의 부족분을 남편이 채우게 되지만, 집안일을 부부의 누군가가 한다면 다른 한 쪽은 안하게 된다는 것을 의미한다. 그러나 주말에는 이러한 관계가 크게 변하게 되는 것을 발견할 수 있었다.

This study grasps the living condition of Single-Parent-Family, and compares Single-Parent-Family with Dual-Parent-Family to analyze necessary factors to enjoy the happier life. The data from '2009 the Korean Time Use Survey' and '2010 the National Survey of Korean Families(NSKF)' are used for this study. ANOVA, Duncan test, Correlation Analysis(SPSS for windows, Ver. 18.0) are used for statistical method. Here are the results of this study. First, distribution of living-time-usage of the Single-Parent-Family is different from that of Dual-Parent-Family. Second, the difference in the amount of leisure time, time distribution, and the content of activity was observed based on the gender of Single-Parent-Family. Third, there is a difference in family leisure activity time among Dual-Parent-Family, Mother-Single-Parent-Family, and Father-Single-Parent-Family in holidays. Fourth, there is a clear difference between Dual-Parent-Family and Single-Parent-Family, after looking at life satisfaction degree in work-family-leisure life experience.

A new intelligent power network (Smart Grid) that grafts some new technologies, such as the extension of the new and reproducible energy, electric motors, and electric storages, onto the regulation of green house gases according to the recent convention on climate changes has been actively promoted. As establishing such an intelligent power network, it is possible to implement a real-time rate system according to the change from the conventional single directional information transmission to the bidirectional information transmission. Such a real-time rate system can provide power during the chip rate hour by avoiding the high rate hour although customers use the same level of power through providing such real-time rate information including power generation costs. In this study, the establishment of an operating system that makes an effective use of the real-time rate system and its operation method are to be proposed.

This study analyze using pattern of the Korean elderly leisure time to know their leisure lifestyle. In order to do this study, we analysed the time use dairy which were collected by Korean National Statistical Office in 1999 and analysis of data was done through mean of time, percentage of acting people hourly. The result of this study were as follows : 1) The elderly spend leisure time average 6 hours 34 minute in a day and enjoy leisure activities from A.M. 11:00 to P.M. 12:00 and from P.M. 8:00 to P.M:. 10:00 mainly. 2) The elderly spend leisure time for acquaintance, using mass media, sports leisure activity and dilettante life. Especially the elderly associate with more others than their family, use more TV than others and spend time for break and amusement as dilettante life.

The purpose of this study was to exam the activities by the distribution of time and space occupancy on their weekday and weekend. to study the space and labor segregation by sex. The sample population included 23 wives and their husbands(30-40 years old). The major findings of the research are as follows: First, it shows that wives' time use by activity was consistent with the space occupancy on weekday. Second, on weekend, wives was used to stay in living room most of time. Thirdly, husbands show the stereotype of time use on weekday, and substitute leisure time for labor time. Finally, on weekend, the wives and husbands have the joint time in the household labor or leisure activities.

We build and analyze some types of queueing model to discuss capacity dimensioning of access links of a LAN interworking unit connected to the Internet backbone network. We assume that the IWU has a FIFO buffer to transmit IP packets to the Internet through the backbone. In order to analyze the system, we use a Poisson process and an MMPP process as input traffic models of IP packets and we use a general service time distribution as a service time model. But we use both an exponential service time and a deterministic service time in numerical examples for simple and efficient performance comparisons. As performance measures, we obtain the packet loss probability and the mean packet delay. We present some numerical results to show the effect of arrival rate, buffer size and link capacity on packet loss and mean delay.

Korea electric power industry had been under vertical monopoly but is typically getting restructured for free competition. An ideal pricing system under the competitive market system is 'unbundled pricing system' and 'marginal pricing system', but the current pricing system still adheres to the traditional bundled system and the average cost pricing system. Especially, progressive electricity rates for residential use reflect governmental policy-making which is focused on income redistribution & welfare, industrial supports and energy saving. This study proposes new and reasonable residential electricity pricing systems which are Time-Of-Use (TOU) and Real-Time Pricing (RTP) to reflect variations in the wholesale price of electricity. It also presents examples of various tariffs for residential electricity pricing systems.
