This Study is to analyze characteristics of costume change of according to the status of character succeeding the investigation of the ceremonial costume change in historical TV dramas that The Empress Myungsung entered. For this study, the costume images among historical TV dramas, that Myungsung entered, '500 years of Chosun Dynastyv, Taewongun(1990, MBC)', 'The Glorious Dawn(1993, KBS1)', 'The Empress Myungsung(2001, KBS2)'were used: The characteristics of the costume change of main character are as follows. First, main character's costume has been increase gradually in number and item. Second, Especially in the last work,'The Empress Myungsung', the royal costume based on historical evidence in aspects of silhouette, but it didn't according to the historical costume in aspects of color and textile. Nevertheless the costume reveals the status of each person significantly. Third, the costumes of the recent historical drama appears as a optical symbol that represents historical view point and different interpretation of each drama. Therefore the costume according to the status of the character wrong from the historical point of view. Consequently, TV costume in historical drama Myungsung entered has been focused on the beauty of the screen and dramatic effect than historical viewpoint. So the costume have been to be an essential visual part by means of the symbol revealed the purpose.

The non-homogeneous Poisson process(NHPP) based software reliability growth models are proved quite successful in practical software reliability engineering. The fault detection rate is usually assumed to be the continuous and monotonic function. However, the fault detection rate can be affected by many factors such as the testing strategy, running environment and resource allocation. This paper describes a parameter estimation of software reliability growth model with change-point problem. We obtain the maximum likelihood estimate(MLE) and least square estimate(LSE), and compare goodness-of-fit.

Objective: Hapkok(L14) and Taechung(Liv3) are acupuncture points located on both sides of each foot and hand of the human body. These two points are called sakwan points. Matching these acupuncture points have a significant reason in pints of not only regulating the circulation of Yin-Yang as a source point of each meridian, but also playing a basic role of twelve meridian by controlling circulation of ki and blood in the whole body. There are already related documents and studies on stimulating sakwan points. Since those papers mostly studied on either hapkook or taechung, we came to have a doubt of stimulation the two point at the same time when an unbalance of Yin-Yang and ki-blood appears. Accordingly, we got to investigate how thermogram of body changes after applying an acupuncture on sakwan points. Our study is as follows ; Method : Our study was performed on 30 normal cases(M:F=17:13) with no past history to observe the effects of the acupuncture. We measured temperature of abdomen and the back of both hands by D.I.T.I(Digital infrared Thermographic Imaging) before and after acupuncture on sakwan points. Results and Conclusions: The thermographic change on abdomen was $0.51{\pm}0.71^{\circ}C$. Temperature of abdomen after acupuncture was higher than before acupuncture with high validity(p<0.01). And the thermographic changes on the back of both hands were right hand $0.54{\pm}1.17^{\circ}C$, left hand $0.56{\pm}1.28^{\circ}C$. Temperature on the back of both hands after acupuncture was higher than before acupuncture, but the difference between them had little validity(p<0.01). In addition, we found that it doesn't necessarily follow that the thermographic changes on abdomen and back of both hands after acupuncture on sakwan points happen concurrently.

The purpose of this study was to determine the effect of systolic blood pressure, heart rate and myocardial oxygen consumption on 3-point nonweight bearing ambulation with axillary wooden crutch according to age. The subjects were fifty healty volunteers(22 male, 28 female), ages from 20 to 69(mean age of 43.8 years) with no history of cardiovascular or respiratory disease, diabetes mellitus, arthritis and orthopedic disorder within the past three years. This study was carried out from May 10 to August 10, 1996. The data were analyzed by percentage, mean and standard deviation and ANOVA. The results were as follows : 1. In systolic blood pressure(SBP), there was no significantly change between before walk and after 20 m in crutch walking with age, however, there did differ significantly after 40 m and 60 m in crutch walking(p<0.01, p<0.001). 2. In heat rate(HR), there was no significantly change between before walk and after 20 m, 40 m in crutch walking with age, however, there did differ significantly after 60 m in crutch walking(p<0.05). 3. In myocardial oxygen consumption($MVO_{2}$), there was no significantly change between before walk and after 20m in crutch walking with age, however, there did differ significantly after 40 m and 60 m in crutch walking(p<0.01, p<0.001). These result showed that cardiovascular system had a great effect on the olderly when 3-point nonweight bearing ambulation with axillary wooden crutch. Therefore, when train for axillary crutch in the olderly, we needed suitably basis of walking distance.

Collective traffic data (BPS, PPS etc.) for detection against the distributed denial of service attack on network is the time sequencing big data. The algorithm to detect the change point in the big data should be accurate and exceed in detection time and detection capability. In this work, the sliding window and discretization method is used to detect the change point in the big data, and propose five nonparametric test statistics using empirical distribution functions and ranks. With various distribution functions and their parameters, the detection time and capability including the detection delay time and the detection ratio for five test methods are explored and discussed via monte carlo simulation and illustrative examples.

This study proposed a model that can track MPP faster than the existing MPPT algorithm using the particle swarm optimization algorithm (PSO). The proposed model highly sets the acceleration constants of gbest and pbest in the PSO algorithm to quickly track the MPP point and eliminates the power instability problem. In addition, this algorithm was re-executed by detecting the change in power of the solar panel according to the rapid change in solar radiation. As a result of the experiment, MPP time was 0.03 seconds and power was 131.65 for 691.5 W/m2, and MPP was tracked at higher power and speed than the existing P&O and INC algorithms. The proposed model can be applied when a change in the amount of power is detected by partial shading in a Photovoltaic power plant with Photovoltaic connected in parallel. In order to improve the MPPT algorithm, this study needs a comparative study on optimization algorithms such as moth flame optimization (MFO) and whale optimization algorithm (WOA).

Due to the frequent emergence of global abnormal climates, related studies on meteorological change is being actively proceed. However, the research on trend analysis using weather data accumulated over a long period of time was insufficient. In this study, the trend of temperature time series data accumulated from automated surface observing system (ASOS) for 40 years was analyzed by using a non-parametric analysis method. As a result of the Mann-Kendall test on the annual average temperature and seasonal average temperature time series data in South Korea, it has shown that an upward trend exists. In addition, the result of calculating the Sen's slope, which can determine the degree of tendency before and after the searched change point by applying the Pettitt test, recent data after the fluctuation point confirmed that the tendency of temperature rise was even greater.

Objectives: Management of the postpartum period is important for the health of mothers, and postpartum edema is one of the management targets. In this study, the relationship between the value measured by the device and the postpartum edema sensation was examined to explain the subjective sensation of the mother as an objective value. Methods: Data from 54 cases provided by 24 mothers within 6 weeks postpartum were used in the study. The degree of postpartum edema sensation was measured using a visual analog scale (VAS), and the effect of VAS changes on the body edema index and weight change before and after childbirth was estimated through linear regression analysis. Results: As a result of the regression analysis, when the edema sensation of the mothers VAS increased by 1 point, the Inbody edema index increased by 0.002 points (p=0.000, R²=0.272), and when the VAS increased by 1 point, the weight gain increased by 0.99 kg compared to before pregnancy (p=0.000, R²=0.243), and when VAS increased by 1 point, weight loss decreased by 0.56 kg compared to just before childbirth (p=0.004, R²=0.136). Conclusions: The results of this study, in which the edema sensation of postpartum mothers was statistically significantly related to the edema index and weight change before and after childbirth, showed that the edema sensation complained by the mother could be used as an evaluation index for postpartum edema management in the future.

The purpose of the study is to identify the point of knowing. The point of knowing is the time, which indicates that 'knowing' occurs in the recognition process. To understand recognition process, the researchers analyzed the questions in units of lessons presented in elementary mathematics textbooks. The researchers analyzed the validity of the point of knowing and found out the basis of the point of knowing. The results are as follows. First, the point of knowing is time to expect to change from a leaner's 'not-knowing' to 'knowing'. Second, the point of knowing can be identified with the questions on textbooks to ask students to do practical action. Third, the point of knowing is closely related to instructional objective in a class. Fourth, in relation to subsidiary awareness and focal awareness, the point of knowing corresponds to focal awareness. Fifth, the point of knowing is equivalent to the inflection point at which personalization/contextualization is changed into depersonalization/decontextualization.
