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.

This study was performed to investigate the masicatory efficiency in patients with temporomandibular disorders (TMDs), especially internal derangement of temporomandibular (TM) joint. For this study, 26 patients after treatment and 33 dental students who had no signs and symptoms of TMDs were selected as the patients group and as the normal group, respectively. Mean treatment duration of the patients was. 5.1 months. Verbal rating scale(VRS) and Visual analogue scale(VAS) were used for recording of subjective symptoms. Treatment index (VAS Ti) derived from VAS was calculated for evaluation of treatment progress and clinical examination was also performed for objective symptoms. BioEGN(Bioresearch Inc., Milwaukee, USA) was used for observation chewing movement pattern on peanut, caramel candy, and gum chewing. Chewing time in second and symptoms after chewing were recorded, and pattern of chewing stroke between in affected side and in contralateral side or between in right in left side were compared, and especially, gum chewing pattern between before and after treatment were also compared in the patients group. The data obtained were analysed by SPSS windows program and the results of this study were as follows : 1. Subjective symptoms evaluated by VAS showed no difference between the two groups, but those by VRS showed slight difference for TM joint pain, head not neck symptoms, and chewing ability. 2. There were no difference at the level of subjective symptoms between the subgroups divided by treatment duration of five months in the patients group. However, value of VAS Ti of pain was higher in subgroup of long treatment duration than that of subgroup of short treatment duration. 3. There were no difference in chewing time for peanut or caramel candy between the two groups, but on caramel candy chewing, the patients group complained slight discomfort after swallowing. Chewing velocity and range of motion on gum chewing after treatment in the patients group showed significant difference and greatly improved compared to those to before treatment, and which were not differ from those of normal subjects. In conclusion, treatment of temporomandibular disorders about for five months would greatly improve chewing ability and movement pattern in most of the patients with TMDs.

This paper presents the design of single phase PFC(Power Factor Correction) using a DSP(TMS320F2812). In order to realize the proposed boost PFC converter in average current mode control, the DSP requires the A/D sampling values for a line input voltage, a inductor current, and the output voltage of the converter. Because of a FET switching noise, these sampling values contain a high frequency noise and switching ripple. The solution of A/D sampling keeps away from the switching point. Because the PWM duty is changed from 5% to 95%, we can#t decide a fixed sampling time. In this paper, the three A/D converters of the DSP are started using the prediction algorithm for the FET ON/OFF time at every sampling cycle(40 KHz). Implemented A/D sampling algorithm with only one timer of the DSP is very simple and gives the autostart of these A/D converters. From the experimental result, it was shown that the power factor was about 0.99 at wide input voltage, and the output ripple voltage was smaller than 5 Vpp at 80 Vdc output. Finally the parameters and gains of PI controllers are controlled by serial communication with Windows Xp based PC. Also it was shown that the implemented PFC converter can achieve the feasibility and the usefulness.

Since 1970, MRI has greatly been developing in terms of strength of magnetic field, the number of receipt channels, and short time of examination. With the development of digital systems and wireless network, hospitals have also acquired, saved, and managed digital images taken by various kinds of medical imaging equipment. However, domestic universities fail to provide practice training course independently thanks to expensive practice equipment and high maintenance cost, and rely on clinical training. Therefore, this study developed a MR patient diagnosis program based on Windows PC to help out students before their working in clinical filed. The designed Relational Database of MRI Simulator is made up of seven tables according to functions and data characteristics. Regarding the designed patient information, each stepwise function was classified by the patient registration method in clinical field. In addition, on the assumption of the basic information for diagnosis, each setting and content were classified. The menu by execution step was arrayed on the left side for easy view. For patient registration, a patient's name, gender, unique ID, birth date, weight, and other types of basic information were entered, and the patient's posture and diagnosis direction were set up. In addition, the body regions for diagnosis and Pulse Sequence were listed for selection. Also, Protocol name and other additional factors were allowed to be entered. The final window was designed to check diagnosis images, patient information, and diagnosis conditions. By learning how to enter patient information and change diagnosis conditions in this program, users will be able to understand more theories and terms learned in practice and thereby to shorten their learning time in actual clinical work.

This study aimed to find the architectural meaning and characteristics of L'Art Sacr? Movement advocated by Dominican Father Marie Alain Couturie. From 1936 till 1954 Father Couturier was the chief editor of the review L'Art Sacr? that became very influential among art critics no longer satisfied with what was considered outdated 19th century church interior decoration. Marie Alain Couturie was a French Dominican friar and Catholic priest who gained fame as a designer of stained glass windows. He was noted for his modern inspiration in the field of Sacred Art. Couturier's greatest ambition was to revive Christian art by appealing to the independent masters of his time. From these viewpoint, we investigated the background and process of the movement and analyzed the architectural meaning and characteristics which represented the Art Sacr? movement. The analyzed chapel buildings were as follows: 1) The Church of Notre-Dame de Toute Gr?ce du Plateau d'Assy, bringing together Braque, Matisse, Rouault, L?ger and Chagall, 2) The Chapel of Saint-Marie Rosaire by Henri Matisse, 3) The Chapel of Notre Dame du Haut and The Couvent de La Tourette by Le Corbusier, and 4) The Rothko Chapel by Mark Rothko and Philip Johnson. These L'Art Sacr? projects inscribedthemselveswithin what was the century's most serious attempt at the reintegration of Art and religious space. Courturier's interactions with artists and architects are traced and shown to have played a major role in the evolution of the priest's thinking and Church interior decoration. At the same time, Courturier's clear and vigorous L'Art Sacr? articles were both defining the theoretical basis of new vision and anticipating the renewal of the religious space.

The purpose of this study is to empirically verify the relationship between supply chain flexibility(process flexibility and logistics flexibility) and competitive advantage strategy(cost, quality, lead time). To accomplish these purposes, the relationships among supply chain flexibility(process, logistics), competitive advantage strategy(cost, quality, lead time) were modeled based on the studies conducted in the various areas. In order to collect the related data the questionaries of 500 were distributed to the employees working at the manufacturing industry in the area of Gumi. The collected data were analyzed with SPSS 18.0 for Windows. This study used the statistical techniques such as descriptive analysis, reliability analysis, factor analysis, correlation analysis, multi regression analysis. The results of the study show that process flexibility had positively significant effect on low cost strategy and high quality strategy and logistic flexibility have positively significant effect on delivery speed strategy. However, it was found that process flexibility did not have the significant effect on delivery speed strategy, and the logistic flexibility did not have the significant effect on low cost and high quality strategy. Thus, it is expected that each enterprise can maximize corporate strategies by applying different flexibility strategy depending on the competitive advantage strategy.

Objectives : The purpose of this study on the oral health behavior of foreign workers and dental care in the community is to identify actual oral health conditions of immigrated labors, to promote their oral health and to gather basic data providing them with proper oral health services Methods : Based on previous studies, The researchers wrote their own surveys in English, in Vietnamnese, in Tagalogue, in Thai. Making questions on the paper to 114 foreign workers in Pocheon, Gyeonggi-do were surveyed. Using the program SPSS 17.0 for Windows, the collected data were analyzed. The frequency analysis, the chi-square analysis and the correlation analysis was performed to recognize their relevance between the oral health status and the actual oral care and the subjective perception of oral health. Results : General characteristics of the foreign workers is the overwhelming majority of male demographic 78.9%. By age, 20-29 years of age accounted for 50%, and duration of stay in the city is less than 3-5 years to 68.4%, It was most common. The percentage going to the dentist when teeth hurt is although 56 percent. But the ratio to endure the pain without going to the dentist, was 44%. The main reason to not go to the dentist was the time 55.2% and cost 11.9%. A mere 9.6% of respondents knew about the free dental care and used. 67.5% of them was not aware of the free dental care agency, 59.6% were keen to use the free care. However, 40.4% did not want a free dental care because they did not have the time(26.3%), the distance is far away(3.5%), and difficulties in communication(3.5%) and the other(66.7%). Conclusions : The major percentage of the other reason(66.7%) why they did not want to go to free dental service, must be specifically identified. For the activation of free dental services, the active support of central and local governments is needed. By focusing on health-related departments of the University in the community, it is necessary to operate the program of the oral health care for foreign workers.
