This paper presents fuzzy clustering and wavelet transform analysis based technique for the industrial hourly load forecasting fur the purpose of peak demand control. Firstly, one year of historical load data were sorted and clustered into several groups using fuzzy clustering and then wavelet transform is adopted using the Biorthogonal mother wavelet in order to forecast the peak load of one hour ahead. The 5-level decomposition of the daily industrial load curve is implemented to consider the weather sensitive component of loads effectively. The wavelet coefficients associated with certain frequency and time localization is adjusted using the conventional multiple regression method and the components are reconstructed to predict the final loads through a five-scale synthesis technique. The outcome of the study clearly indicates that the proposed composite model of fuzzy clustering and wavelet transform approach can be used as an attractive and effective means for the industrial hourly peak load forecasting.

Utilization practice of garlic and seasonings in industry foodservice was surveyed by questionnaire. Statistical data analysis was performed with SAS package program in order to have frequencies, means, t-test, ANOVA and Duncan's multiple range test. The results of this study can be summarized as follows; The mean value of Food Processing Index(FPI) score for purchased vegetable and seasonings is 3.5 which indicates the prepreparation is between partially preprepared and completely preprepared. The garlic was mainly purchased from brokers(51.0%), on a daily basis(58.8%) and peeled-form(74.5%). The average purchased amount is 6.66㎏ at a time. The unit price of the garlic makes significant differences(p＜0.05) by the scale and location of foodservice establishments. As for the storage method and Period, in room temperature, no storage(2.1%) and for one day(2.1%) and in refrigeration, for one day(39.6%) and fer three days(18.7%).

The home environments, daily activities, caregiving behaviors of mothers, infant's verbal behaviors, attachment to mothers of home-reared infants from low SES families were observed. 30 two-year-old home-reared infants and their mothers were observed at home by the time sampling method. The HOME scale, the behavioral checking lists for caregiving behaviors and for the infants' verbal behaviors, and the Attachment Q-set were used for the observation. the total HOME scores were in the middle range and the scores of "Provision of apropriate play materials" was relatively high, but "Avoidance of restriction and physical punishment" was low. The most frequent caregiving behaviors shown by mothers were " Facilitating verbal development" and "Positive social-emotional inputs". The most frequent verbal behaviors shown by infants were " Information exchange" and " Language interpretation" . The infants' attachment security scores of their mothers tended to be low.

Objectives : This case series was conducted to report the efficacy of Ondam-tanggami for insomnia. Methods : Insomnia patients with more than 15 points on Insomnia Severity Index scale were assessed using SCL-90-R, STAI, STAXI, BDI. Being treated with Ondam-tanggami after 2 weeks, ISI, STAI, STAXI, BDI were re-measured to determine the progress of insomnia. It is measured that total sleep time, number of awaking times during sleep, satisfaction of sleep daily. Results : After treatment, quality of sleep has improved and ISI, STAI, STAXI, BDI score have decreased. Conclusions : According to the study, treatment with Ondam-tanggami for insomnia has shown positive results. Further use of Ondam-tanggami is much anticipated for future treatment of insomnia cases.

The fluctuation of inlet flow to a water treatment plant makes a serious problem that it can change the outlet flow-rate from each process abruptly, and ultimately occur the detachment of the attached particles inside each unit process. Also, since it takes very short time for the surface wave occurred from the fluctuation of inlet flow to reach the latter processes, it is impossible for operators to cope with that stably. Therefore this study was conducted to suggest the methodology for accurately predicting the travel time of surface wave occurred from the fluctuation of inlet flow to reach the latter process. Through the experiment, which was carried out for the full-scale water treatment plants(capacity : 2,000m3/d), it could be confirmed that the flow rate fluctuation from equalization tank produce the surface wave. And the wave transfer velocity is a function of the hydraulic radius and the length of each open type tanks which are comprised in the latter processes.

Purpose: This study analyzed the effects of meridian massage on the muscle power, ROM, and ADL in persons with cerebral palsy. Method: A non-equivalent pre-test/post-test design was used. The data were collected from August to October, 2000 from 10 persons with cerebral palsy (a control group of 5 and an experimental group of 5). Muscle power was evaluated with the Brunnstrom-Dennen gravity test, ROM with a goniometer, and ADL with a self developed ADL scale. T-test, repeated measure ANOVA were used for statistical analysis. Result: The results are; 1. For muscle power, both time series group difference (F=10.66, p=0.000) and the total period group difference (F=72.67, p=0.000) were significant between the two groups. 2. ROM was not significantly different between the two groups. 3. For ADL, both time series group difference (F=7.09, p=0.001) and total period group difference (F=35.99, p=0.000) were significant between the two groups. Conclusion: Overall, this study shows that Meridian massage is effective for muscle power, ROM, and ADL in persons with cerebral palsy person. So it can be used to develope effective nursing programs to improve the function of motion of persons with cerebral palsy.

Objectives : The aim of this study is to report the improved case of bilateral avascular necrosis(AVN) of femur head treated with Korean medicine and Fascia Chuna Therapy Methods : The patient diagnosed with bilateral AVN is hospitalized at department of korean rehabilitation medicine, Samse hospital of korean medicine. The subject is treated by herbal medicine, acupuncture, SBV and hip joint gyoung-geon chuna. This study was measured by visual analogue scale(VAS) score, walking time without pain per 6 minutes and harris hip score(HHS).

Purpose: The purpose of this study was to investigate the predictors of delirium in patients after orthopedic surgery. Methods: Participants were 121 orthopedic surgery patients from one university affiliated hospital located in Seoul. The instrument of Delirium Observation Screening Scale (DOS) developed by Schuurmans et al. (2003) was utilized. Data were collected from September 1st, 2010 to March 31st, 2011 and analyzed using SPSS 12.0 with descriptive statistics, t-test, chi-square test and logistic regression. Results: The delirium in patients after orthopedic surgery was occurred in 9 (7.4%) out of 121 patients. Several factors were associated with the delirium occurrence age, admission route, preadmission Activity of Daily Living (ADL), preadmission hearing aid use, preadmission walking degree, diagnosis, type of surgery, Intensive Care Unit (ICU) stay after surgery, restraint, drainage tube, time of admission to surgery, preoperative albumin and preoperative sodium. Preadmission ADL, preoperative sodium and time of admission to surgery were the significant predictors of the delirium occurrence. Conclusion: Study results may help nurses predicting and detecting delirium early and providing preventive measures to the patients with high risk of delirium after orthopedic surgery.

생태계 내에서 개체군 변동을 이해하는데 다양한 시간 스케일에서의 분석이 유용한 방법이 될 수 있다. 최근까지 다양한 시간 스케일에서의 개체군 변동에 대한 연구는 거의 드물다. 본 연구는 2014년부터 2017년까지 4년간 충남 당진시 석문면 논에 도래하는 백로류 개체군을 대상으로 시간 스케일에 따른 이들 개체군 변동에 영향을 미치는 요인을 확인하기 위해 수행되었다. 백로류는 황로, 왜가리, 중대백로, 중백로, 쇠백로만을 대상으로 하였으며, 고정된 지점에 설치된 무인모니터링 시스템을 활용하여 백로류의 개체군 변동을 다른 시간 단위의 스케일인 월 단위와 일 단위 변동으로 나누어 확인하였다. 그 결과, 월별 개체군 변동에 영향을 미치는 요인은 시기, 평균 온도, 평균 강수량으로 나타났고, 일별 개체군 변동에 영향을 미치는 요인은 평균 온도와 서식지 유형이 중요한 것으로 확인되었다. 시기의 통계적 유의성이 일 단위에서는 나타나지 않고 월 단위에서 확인된 이유는 백로류의 논 이용 패턴이 일 단위보다는 월 단위 스케일에서 명확히 구별되기 때문으로 판단된다. 이를 통해 시간 스케일에 따라 백로류에 영향을 미치는 요인에 차이가 있다는 것을 확인할 수 있었다.
