According to the KT telecommunication statistics, people stayed inside their houses on an average of 11.9 hours a day. As well as, according to NSC statistics in the united states, people regardless of age are injured for a variety of reasons in their houses. For purposes of this research, we have investigated an abnormal event detection algorithm to classify infrequently occurring behaviors as accidents, health emergencies, etc. in their daily lives. We propose a fusion method that combines three classification algorithms with vision pattern, audio pattern, and activity pattern to detect unusual user events. The vision pattern algorithm identifies people and objects based on video data collected through home CCTV. The audio and activity pattern algorithms classify user audio and activity behaviors using the data collected from built-in sensors on their smartphones in their houses. We evaluated the proposed individual pattern algorithm and fusion method based on multiple scenarios.

Kalman Filter model of demand for residental water and consumption pattern were tested for their ability to explain the hourly residental demand for water in metropolitan distribution system. The hourly residental demand for water is calculated from the daily residental demand and consumption pattern. The consumption pattern which has 24 time rates is characterized by data granulization in accordance with season kind, weather and holiday. The proposed approach is applied to water distribution system of metropolitan areas in Korea and its effectiveness is checked.

이 연구에서는 인터넷이 일상생활에 도입되면서 전반적인 생활시간 패턴에 변화를 가져온다는 관점에서 연구문제를 설정하였다. 새로운 매체가 등장했을 때 기존의 전통적 매체이용 시간에 대한 대체 혹은 보완 여부에만 주목할 경우, '미디어 고립주의'에 빠질 위험이 있다. 이뿐만 아니라 연구 결과가 일관되지 못하다는 한계점도 지적되어 왔다. 따라서 인터넷 이용 행동이 일상적 활동 영역에 미치는 영향을 거시적으로 살펴볼 수 있도록 하기 위해 2000년과 2005년도의 국민생활시간조사 자료를 통시적으로 분석함으로써 기존 연구(이재현, 2005)에서 제안된 시간 재할당 가설을 검증, 보완하고자 하였다. 먼저 연령대별로 인터넷 이용자와 비이용자 간에 일상적 활동 영역 및 매체 이용 영역에서 나타나는 시간 소비량의 차이를 검정한 후, 유의미한 차이를 보인 활동 영역에 대해서는 로지스틱 회귀분석을 통해 인터넷 이용 유무에 따른 생활시간 이용 패턴의 차이를 종합적으로 살펴보았다. 연구 결과, 2000년도와 인터넷 사용자가 급증한 2005년도의 경우를 비교했을 때 대부분의 연령 집단에서 생활시간 패턴이 재조직화되고 있음을 확인하였으며, 특히 젊은 연령층일수록 시간 재할당 현상이 더 일찍, 더 뚜렷이 나타나는 경향을 보였다.

SNS사용자의 거주 지역을 유추하여 그들이 생성한 데이터에 거주위치를 부여하는 것은 위치희박(location sparsity)과 생태학적 오류문제로 인해 연구결과의 신뢰성이 떨어진다는 평가를 받아온 공간빅데이터 연구에 대안이 될 수 있다. 본 연구에서는 Tweet 사용자의 거주 지역을 유추하는 방법으로 사용자 타임라인데이터 속에서 찾아낸 일상생활활동패턴을 이용하는 방법을 고안하였다. 트윗 사용자의 일상생활활동패턴은 이동궤적과 사용자의 언어(text)에서 확인할 수 있었으며 전자를 활용한 모델을 일상이동패턴모델, 후자를 활용한 모델을 일상 활동장 모델이라 명명하고 각각 모델에 입력될 변수를 선정하였다. 자신의 거주 지역에서 가장 높은 빈도의 트윗 발생 여부와 가장 높은 빈도의 거주행정구역 표현 단어를 사용하는지 아닌지를 종속변수로 한 판별분석을 실시하여 모델을 작성하였으며 설명력은 일상 이동패턴모델, 일상 활동장 모델 각각 67.5%, 57.5%였다. 이 모델을 스트레스 관련 트윗을 작성한 사용자의 타임라인데이터로 구성된 테스트데이터에 입력해본 결과 전체 사용자 48,235명 중 5,301명의 거주 지역을 유추하였고 이를 활용하여 위치 부여된 스트레스 관련 트윗 9,606개를 확보하였다. 본 연구의 유추기법을 통해 기존 SNS데이터 분석연구에서 사용하는 데이터 수집 방법보다 44배 많은 위치 부여 트윗을 확보할 수 있었다. 본 연구방법론은 SNS데이터를 이용한 연구에서 위치 부여된 데이터를 확보하는데 활용 가능할 것으로 판단되며, 각종 지역통계와 상관관계파악을 통해 지역적 현상 분석에도 SNS데이터를 이용할 수 있는 가능성을 높일 것으로 판단된다.

This Study is on the excavated clothing from lady Lee' tomb in spring 2003, on Chungjoo Province. These are significant as the 18th century's real clothing, we examine the real Jegories as possible and the results shows there are two group in sizes. we regard the large Jegori is for the dead as a shroud, the small one is for daily. it shows that Jegori for the dead is about 1.3 larger than a daily one, we can see Jegori for the dead was going to be large from the 18th century, and it's needlework was not fine than daily one, but the Color and the material on should look like as daily in this time, and the motif is cloud pattern, we can see two changes in daily Jegori that one thing is to be short and narrow, the other is to be curve at the corner of collar(Gitmuri), the corner of edge(supco), the below line of sleeve(baerae) in the daily Jegori.

Objective: Environmental change is one of the stressful events in livestock production. Change in environment disturbs cow behavior and cows require several days to regain a stable behavioral pattern. Sleeping posture (SP) and lying posture (LP) have been used as indicators for animal that are relaxed and well-acclimated to their environment. The aim of this study was to examine the time required by Japanese black cows for stabilization of SP and LP after moving into new environment. Methods: Seven pregnant Japanese black cows were used. Cows were moved into new tie-stall shed and their sleeping and lying posture measured 17 times during 35 experimental days. Both SP and LP were detected by accelerometer fixed on middle occipital and hip-cross, respectively. Daily total time, frequency, and average bout of both SP and LP were calculated. Results: Daily SP time was the shortest on day 1 and increased to the highest on day 3. It then decreased until day 9, after that stabilized about 65 min/d till the end of experiment. Daily LP time changed in same manner as daily SP time. The average SP bout was the longest on day 1, and then decreased to stable level on day 7. On the other hand, the average LP bout was the shortest on day 1, and it increased to stable level on day 7. Conclusion: These results showed that pregnant Japanese black cows needed 1 week to stabilize their SP. However, there were different change patterns between the average SP and LP bout, even though the change pattern of daily SP and LP time were similar.

To examine the trend on the flowering time in some weather flora including Prunus serrulata var. spontanea, Cosmos bipinnatus, and Robinia pseudo-acacia in Busan, the changes in time series and rate of flowering time of plants were analyzed using the method of time series analysis. According to the correlation between the flowering time and the temperature, changing pattern of flowering time was very similar to the pattern of the temperature, and change rate was gradually risen up as time goes on. Especially, the change rate of flowering time in C. bipinnatus was 0.487 day/year and showed the highest value. In flowering date in 2007, the difference was one day between measurement value and prediction value in C. bipinnatus and R. pseudo-acacia, whereas the difference was 8 days in P. mume showing great difference compared to other plants. Flowering time was highly related with temperature of February and March in the weather flora except for P. mume, R. pseudo-acacia and C. bipinnatus. In most plants, flowering time was highly related with a daily average temperature. However, the correlation between flowering time and a daily minimum temperature was the highest in Rhododendron mucronulatum and P. persica, otherwise the correlation between flowering time and a daily maximum temperature was the highest in Pyrus sp.

Morning grooming is a ritual daily held for transition from private to public life of an individual. Based on the previous literature's definition of the ritual characteristics, this study aims to identify the meaning of grooming rituals that are repeatedly performed every morning. Although many studies have conducted ritualistic analysis of the behaviors that are closely related to daily life, few studies analyze grooming from a ritualistic perspective. Establishing the ritual - that is, a person's distinct behavioral pattern-as the core concept, this study reveals the relationship between ritual performers and the ritual's composition to identify the meaning of the grooming ritual. The study conducts qualitative research with ten participants to identify the ritual characteristics of every-morning grooming and the factors that influence this ritual. Considering everyday grooming as a behavioral pattern that possesses mostly ritualistic elements, the study examines both the external characteristics that are shown through the methods of grooming and the internal characteristics that reflect the inherent symbolic meaning. This study contributes to extending the scope of the field. By understanding the factors that influence grooming rituals, companies can communicate their marketing messages regarding the step-by-step approach to grooming, thereby supporting consumers to effectively use various grooming products.

This paper presents a novel approach for extracting simultaneously human daily activity patterns and discovering the temporal relations of these activity patterns. It is necessary to resolve the services conflict and to satisfy a user who wants to use multiple services. To extract the simultaneous activity patterns, context has been collected from physical sensors and electronic devices. In addition, a context model is organized by the proposed incremental statistical method to determine conflicts and to infer user intentions through analyzing the daily human activity patterns. The context model is represented by the sets of the simultaneous activity patterns and the temporal relations between the sets. To evaluate the method, experiments are carried out on a test-bed called the Ubiquitous Smart Space. Furthermore, the user-intention simulator based on the simultaneous activity patterns and the temporal relations from the results of the inferred intention is demonstrated.

Clinical and epedemiologic studies of coronary heart disease(CHD)have from time to time over the last three decades found associations between prevalence of CHD and behavioral attributes and cigarette smoking. The main purpose of this study is reduced to major risk factor of coronary heart disease through prohibition of smoking and control of behavior pattern. The subjects consisted of 120 smokers and 90 non-smokers who were married men older than 30 years working in officers. The officers were surveyed by means of questionnaire September 26 through October 6, 1989. The Instruments used for this study was a self-administered measurement tool composed of 59 items was made through modifications of Jenkuns Activity Survery(JAS). The Data were analysed by SAS(Statistical Analsis System) program personal computer. The statistical technique used for this study were Frequency, x$^2$-test, t-test, ANOVA, Pearson Correlation Coefficient. The 15 items were chosen with items above 0.3 of the factor loading in the factor analysis. In the first factor analysis 19 factors were extracted and accounted for 86% of the total variance. However when the number of factors were limited to 3 in order to derive Jenkins classification, three factors were derived. There names are Job-Involvement, Speed & Impatience, Hard-Driving. Each of them includes 21 items, 21 and 9, respectively. The results of this study were as follow : 1. The score of the smoker group and non-smoker group in Job-Involvement(t＝5.7147, p＜0.0001), Speed & Impatience(t＝4.6756, p＜.0001), Hard-Driving(t＝8.0822, p＜.0001) and total type A behavior pattern showed statistically significant differences(t＝8.1224, p＜.0001). 2. The score of type A behavior pattern by number of cigarettes smoked daily were not statistically significant differences. 3. The score of type A behavior pattern by duration of smoking were not significant differences. It was concluded that the relationship between smokers and non - smokers of type A behavior pattern was statistically significant difference but number of cigarettes smoked daily and duration of smoking were not significant differences. Therefore this study is needed to adequate nursing intervention of type A behavior pattern in order to elevated to educational effect for prohibition of cigarette smoking.
