This study was done to analyze the effects of prompted voiding therapy on urinary incontinence in elderly patients in an elderly care hospital. Specifically, this study looks to evaluate the effects of prompted voiding as an intervention for improving independent voiding and also identified the relationship of urinary continence to cognitive, emotional, and physical factors. The study was based on a pre-experimental design used to evaluate the effects of prompted voiding therapy on an experimental group without a control group. An experimental group of 143 patients was selected through convenience sampling from patients in an elderly care hospital. The data was collected from November 4 to December 14, 1996. Prompted voiding therapy is a behavioral therapy for managing incontinence and it is applied to patients who are cognitively impaired and dependent. In this study, the patients were asked at each designated time whether or not they had to urinate. If they answered yes, they were either given a bedpan or were assisted to the bathroom, and if the patient answered no, their diaper was checked to determine whether or not it was wet. The results were then recorded on the patients urinary voiding record. The urinary voiding score based on the model presented by Burton(1984), Burke and Walsh(1992), Chenitz, Stone & Salisbury(1991) was modified and used as a tool in this study. After forty six out of the total of 143 patients were selected for interviews through random sampling the levels of cognitive functions, mental depression and ADL(activities of dally life) within the given time frame were measured. In this study, the cognitive function was measured using the scale developed by Kabhn, Goldfarb, Pollack & Peck(1960), elderly mental depression, using the tool developed by Sheikh & Yesavage(1986), and the ADL(activities of dally living), through the Barthel Index. The data was analyzed through SPSS windows for descriptive statistics, repeated measured ANOVA and Pearson's correlation. According to the results of the study, the application of the prompted voiding therapy can improve the voiding pattern of patients. It was shown especially that incontinence could be controlled by the intervention developed according to the individual voiding pattern. In terms of the relationship between cognitive function, mental depression and ADL and the voiding function score, a close correlation was not found. It was shown that urinary incontinence can be improved through therapy even though patients have problems nth their cognitive, mental and physical functions.

A small hydro-power plant using the seawater used as the cooling (circulated) water and discharged is under construction. The bigger size of the small hydro-power plant, the better in order to maximize the efficiency and the electric power. The optimal size, however, should be determined in the constraints of the channel un-disturbed range. The water level change should be checked in detail based on the hydraulic behaviour. In this study, the FLOW3D model, three-dimensional flow model, is setup using the flow measurement data in the effluent discharge channel and the flow pattern changes due to the small hydro-power plant construction are predicted by the model. The plant construction makes the increasing of the water level, and the water level in the upstream of the channel weir is increased 65 cm from 4.32 m to 4.97 m, in the condition of the design discharge $156m^3/s$ and the movable weir height of the hydro-power plant 3.8 m.

The electrophoretic variations in protein and some enzymes during stratification of Panax ginsseng seeds were checked in relation to the differentiation and development of immature embryo, Seed-protein on PAGE showed eight major bands during the period of investigation, Four bands of Rf : 0.12, 0.24, 0.66 and 0,72 remained in dark stained condition, whereas the remainders (Rf : 0.40, 0.48, 0.56 and 0,76) became lighter in the staining condition as the treatment period was prolonged, In embryo, which was separately sampled from 75 days after the treatement, the only band of Rf 0.76 was not observed, In peroxidase, the number of bands was gradually increased and came to four bands at 45 days after treatment, and their staining color became gradually darker until the time of final samling. Also, the embryo had the same patterns as those in the intact seed. Esterase showed four bands during the period of investigation. As the treatment period was prolonged, the degree of staining condition came to darker in the band of Rf 0.36, but lighter in the band of Rf 0.56. The band of Rf 0.20 was not detected in the intact seed at 90 days after the treatment, but clearly observed in embryo. Glutamate dehydrogenase had only two bands: one (Rf : 0.16) was detected only at 60 days after the treatment and the other (Rf: 0.14) was always observed throughout the period, and showing simple pattern in the electrophoretic variation. Glutamate-oxaloacetate transaminase showed the only band of Rf 0.36 during the period of investigation and even in embryo, and showing the simplest pattern, indeed.

Purpose - Studies of mechanism as a competitive strategy, a relatively new field in the study of strategic management research, has recently drawn the attention of the business management scholars. The literature has so far proposed the subjective-based view, environment-based view, and the resource-based view in its analyses of firm management. Hence, it is highly likely for the firm management to be reasonably thought of as a combination of and interaction among the three key elements of subject, environment, and resources this is the mechanism-based view (MBV). It is reasonable to consider firm management to be the combination of and interaction among the three key elements of subject, environment, and resources. The overall dynamic process that integrates these three elements and creates functional harmony is identified as the mechanism, the principle of firm management. Much of the extant literatures on MBV has mainly focused on case studies, a qualitative approach prone to subjectivity of the researcher, although the intuition from the study may lead to meaningful insights into a firm-specific mechanism. This study's focus is also on case analysis, but it still attempts a quantitative approach in order to reach a scientific and systematic understanding of the MBV. Research design, data, and methodology - I used both a qualitative and quantitative approach to a single model, given the complexity of the innovation processes. I conducted in-depth interviews with POSCO employees-20 from general management, two from human resources, eight from information technology, five from finance and accounting, and five from production and logistics management. Once the innovative events were selected, the interview results were double-checked by the interviewees themselves to ensure the accuracy of the answers recorded. Based on the interview, I then conducted statistical validation using the survey results as well. Results - This study analyzes the building process of innovation and the effect of the mechanism pattern on innovation by examining the case of POSCO, which has survived over the past 21 years. I apply a new analytical tool to study mechanism innovation types, perform a new classification, and describe the interrelationships among the mechanism factors. This process allows me to see how the "Subject"factor interacts with the other factors. I found that, in the innovation process of the adoption stage, Subject had a mediating effect but that the mediating effect of resource and performance was smaller than the effect of Subject on performance alone. During the implementation stage, the mediating effect of Subject increased. Conclusion - Therefore, I have confirmed that the subject utilizes resources reasonably and efficiently. I have also advanced mechanism studies: whereas the field's research methods have been largely confined to single case studies, I have used both qualitative and quantitative methods to examine the relationships among mechanisms.

In order to extract and analyze complex features of the behavior of animals in response to external stimuli such as toxic chemicals, we implemented an adaptive computational method to characterize changes in the behavior of chironomids in response to treatment with the insecticide, diazinon. In this paper, we propose an energy minimization model to extract the features of response behavior of chironomids under toxic treatment, which is applied on the image of velocity vectors. It is based on the improved active contour model and the variations of the energy functional, which are produced by the evolving active contour. The movement tracks of individual chironomid larvae were continuously measured in 0.25 second intervals during the survey period of 4 days before and after the treatment. Velocity on each sample track at 0.25 second intervals was collected in 15-20 minute periods and was subsequently checked to effectively reveal behavioral states of the specimens tested. Active contour was formed around each collection of velocities to gradually evolve to find the optimal boundaries of velocity collections through processes of energy minimization. The active contour which is improved by T. Chan and L. Vese is used in this paper. The energy minimization model effectively revealed characteristic patterns of behavior for the treatment versus no treatment, and identified changes in behavioral states .is the time progressed.

While the concept of Home Network is laying by and its interests are increasing by means of digitalizing of the information communication infrastructure, many efforts are in progress toward convenient lives. Moreover, as information household appliances which have a junction of connecting to the network are appearing over the past a few years, the demands against intellectual Home Services are increasing. In this paper, by being based upon Multimedia which is an essential factor for developing of various application services on ubiquitous computing environments, we suggest a simplified application model that could apply the information to the automated processing system after studying user's behavior patterns using authentication and access control for identity certification of users. In addition, we compared captured video images in the fixed range by pixel unit through some time and checked disorder of them. And that made safe of user certification as adopting self-developed certification method which was used 'Hash' algorism through salt function of 12 byte. In order to show the usefulness of this proposed model, we did some testing by emulator for control of information after construction for Intellectual Multimedia Server, which ubiquitous network is available on as a scheme so as to check out developed applications. According to experimental results, it is very reasonable to believe that we could extend various multimedia applications in our daily lives.

To evaluate the feeding effect of oriental medicine on the functional properties of pork, male pigs(Sus scrofa var. domesticus L.) were fed commercial basic diets containing 1.0%, 3.0% and 7.0% of oriental medicine complex from 30 or 45 days before slaughter. The growth pattern and physical conditions of pigs during the feeding period were checked, and after slaughter, the taste of pork and biological characteristics of serum were analyzed. Body weight gain was significantly increased in case of 45 day feeding groups of 3.0 and 7.0% compared with control group (p<0.05), whereas food intakes were slightly decreased in these groups. Triglyceride and total cholesterol levels were effectively decreased in the same feeding groups compared with control group (p<0.01~0.001). Three percent feeding group not only effectively decreased the LDL-cholesterol levels, but also sig-nificantly decreased the atherogenic index in 30 days(p<0.001). Malondialdehyde levels and hy-droxyl radical formations were effectively inhibited in all oriental medicine feeding groups. Superoxide dismutase activities were effectively increased only in 3.0% feeding groups, HDL-cholesterol levels almost did not change in 3.0% and 7.0% feeding groups in 30 days. External and sensory evaluations make satisfactory results in all oriectal medicines feeding groups. According to the experimental results, the growth pattern and physical nomditions of the pigs fed oriental medicine without feeding any antibiotics were relatively superior to those of control group. The authors suggest that, if more than 3.0% of oriental medicine were fed to the pigs from more then 30 days before slaughter the pork is reatively better than those of general pork not only for the modulating the chronic degenerative diseases, but also for its qualities and tastes.

Introduction: Very high aggressiveness and recurrence are important clinical characteristics of ameloblastoma compared to the other benign tumors. Therefore, an accurate diagnosis and treatment plan is important. This study examined the association of the clinical findings and recurrence based on the radiological findings of ameloblastoma. In recurrent cases, these results are expected to help in the diagnosis and treatment of ameloblastoma to examine the relevance with the clinical characteristics and radiological features. Materials and Methods: For a clinical (gender, age) and radiological (location, internal pattern, size, perforation, border pattern, impacted tooth, root resorption) evaluation, this study examined 156 cases of 147 patients diagnosed with ameloblastoma, who had been treated and in most cases regularly checked at the department of oral and maxillofacial surgery, Kyungpook National University Hospital, between January 1993 and December 2009. For a recurrent rate evaluation, a more than 3 years follow-up period is needed. Accordingly, 116 patients diagnosed with ameloblastoma between January 1994 and December 2007 were investigated. Results: The recurrence rate in all cases was 6.1% but was 7.8% in cases with follow-up periods more than 3 years. The male-to-female ratio was 3:2, showing a slight male predilection. Ameloblastoma had a peak occurrence in the second decade of life followed by the fourth decade of life. The mandibular angle area is the most frequent site of ameloblastoma (50.8%) in the jaws. Six cases of unilocular (7.8%) and 3 cases of multilocular (7.7%) ameloblastomas recurred. Seven cases of smooth (10%) and 2 cases of irregular (4.3%) ameloblastomas recurred. No cases of ameloblastomas without perforation of the cortical bone (0%) and 9 cases with a perforation of cortical bone (11.1%) recurred. Four cases of the ameloblastomas with impacted teeth (11.4%) and 5 cases of ameloblastomas without impacted tooth (6.2%) recurred. Seven cases of ameloblastomas with root resorption (10.9%) and 2 cases of ameloblastomas without root resorption (3.8%) recurred. Conclusion: A multiple smooth margin, unilocular ameloblastoma with an impacted tooth, root resorption tends to recur more easily. Therefore, they need to be treated more carefully and require a a longer follow-up.

The purpose of this study is to suggest the methodology for the computation of uplift pressure and discharge of the seepage flow under gravity dam. A 3-dimensional FDM model is developed for this purpose and this model can simulate the saturated Darcian flow in heterogeneous media. For the verification of the numeric model, test simulation has been executed and the mass balance has been checked. The error does not exceed 3%. Using the developed model, The uplift pressure and seepage flow discharge under gravity dam has been calculated. The uplift pressure shows the similar pattern, comparing with the result of flow-net method. As the length of grout curtain increases, the uplift pressure decreases linearly, but the seepage flow discharge shows the non-linear decreasing pattern. The coefficients of the formulas in the dam-design criteria have been analysed, and ${\alpha}=1/3$ corresponds to the value when the length of curtain grout is 70% of the aquifer height. The uplift pressure near the pressure relief drain has the big curvature vertically and horizontally. The developed model in this study can be used for the evaluation of the effects of seepage flow under gravity dam.

The recent steep increase in the minimum hourly wage has increased the burden of labor costs, and the share of unmanned stores is increasing in the aftermath of COVID-19. As a result, theft crimes targeting unmanned stores are also increasing, and the "Just Walk Out" system is introduced to prevent such thefts, and LiDAR sensors, weight sensors, etc. are used or manually checked through continuous CCTV monitoring. However, the more expensive sensors are used, the higher the initial cost of operating the store and the higher the cost in many ways, and CCTV verification is difficult for managers to monitor around the clock and is limited in use. In this paper, we would like to propose an AI image processing fusion algorithm that can solve these sensors or human-dependent parts and detect customers who perform abnormal behaviors such as theft at low costs that can be used in unmanned stores and provide cloud-based notifications. In addition, this paper verifies the accuracy of each algorithm based on behavior pattern data collected from unmanned stores through motion capture using mediapipe, object detection using YOLO, and fusion algorithm and proves the performance of the convergence algorithm through various scenario designs.
