Purpose: The purposes of this study were to understand the types of coping strategies that family caregivers experience during the process of caring demented elderly: to grasp the coping strategies used for resolving this problem: and to develop a substantive theory by analyzing the coping types of the family caregivers of demented elderly. Method: The methodology of data collection and analysis used in this study was grounded theory proposed by Strauss and Corbin (1990). The data was collected through in-depth interviews with participants using open-ended and descriptive questions about their coping experiences. All data were were audio-taped and transcribed. The data were collected from February, 2000 to February, 2001. The participants of this study were 17 women. Results: Caregiver's coping types varied according to 'family's support', 'the condition of caregiver's health', 'the relationship with dementia elderly', 'family perception of dementia', 'fixed idea of traditional female role' and 'economic state'. In this study, five types of coping strategies were emerged: active role allotment tyle, meaning grant tyle, devotion tyle, duty defense type, and pessimism type. Among these, those who belong to the types of active role allotment, meaning grant, and devotion, including caregiver's good health were found to adapt themselves to caregiver roles. Conclusion: The results of this study may be helpful for developing effective and individualized nursing strategies suitable for individual caregivers coping types. It is suggested to practice nursing mediation and to analyze the changes in nursing effect and family members' adaptation based on coping types of the well-adapted caregivers as we as on their affirmative coping strategy.

In mathematics education, teaching-learning activity can be divided largely into the understanding the mathematical concepts, derivation of principles and laws, acquirement of the mathematical abilities. We utilize various media, teaching tools, audio-visual materials, manufacturing materials for understanding mathematical concepts. But sometimes we cannot define or explain correctly the concepts as well as the derivation of principles and laws by these materials. In order to solve the problem we can use the computer. In this paper, character and movement state of various quadratic function graph types can be used. Using the computers is more visible than other educational instruments like blackboards, O.H.Ps., etc. Then, students understand the mathematical concepts and the correct quadratic function graph correctly. Consquently more effective teaching-learning activity can be done. Usage of computers is the best method for improving the mathematical abilities because computers have functions of the immediate reaction, operation, reference and deduction. One of the important characters of mathematics is accuracy, so we use computers for improving mathematical abilities. This paper is about the program focused on the part of "the quadratic function graph", which exists in mathematical curriculum the middle school. When this program is used for students, it is expected the following educational effect. 1, Students will have positive thought by arousing interests of learning because this program is composed of pictures, animations with effectiveness of sound. 2. This program will cause students to form the mathematical concepts correctly. 3. By visualizing the process of drawing the quadratic function graph, students understand the quadratic function graph structually. 4. Through the feedback, the recognition ability of the trigonometric function can be improved. 5. It is possible to change the teacher-centered instruction into the student-centered instruction. For the purpose of increasing the efficiencies and qualities of mathmatics education, we have to seek the various learning-teaching methods. But considering that no computer can replace the teacher′s role, tearchers have to use the CIA program carefully.

The purpose of this study was to investigate teacher's perceptions about the nutrition education of elementary schools. A total of 226 elementary school teachers within Changwon and Milyang city participated in this study. The results of this study were as follows. 90.8% of the teachers responded that nutrition education is necessaty in the elementary schools, and positive responses in the Milyang urban area were higher than that of the Changwon rural area(p＜0.001). The main reason for the necessity of nutrition education was for proper growth and good table manners and the Milyang urban city was significantly higher than three other classes in ‘for proper growth’(p＜0.05). The starting period for nutrition education was supported by 72.1% of the teachers as beging when the children are in kindergarten, proving that this early nutrition education is supported. Especially in the Changwon urban support was higher than in the three other classes(p＜0.01). The perceptions about a suitable person to teach nutrition indicated parents(39.6%), dietitions(35.5%), class teachers(24.9%), and the beliefs about nutrition specialists or dietitions was very low. 53.6% of the teachers responded that they would not teach nutrition education themselves and the main reason for this was that believed the teacher's work would be too hard(32.0%), lack of nutrition knowledge(29.4%), and that such courses should be taught courses by specialists(29.4%). However, 51.6% of the teachers disagreed with having a separate course for nutrition education. Proper eating habits(62.7%) and growth and nutrition(28.6%) were the main categories within nutrition education. The teacher recognized that elementary students' nutrition problem is to eat too much processed and instant foods(39.1%), deviated foods(36.9%), and lack of table manners(19.4%). The most effect method was to link the subject matter with the parents(38.7%), use of audio visuals and education materials(28.3%), and need of nutrition education teachers(10.1%) was low.

This is an experimental study that aimed to find out a possible relationships between the noise of the ship and the intelligent quotient, and the creativity of the crew member during June 5, to August 24, 1975. The experiment was carried out on the university training ship, the Oh-Bae-San Ho(1,126 tons), and the Kwan-Ak-San Ho (243 tons) and the training ship Baek-Kyung Ho (380 tons) of Je-ju College, where the total number of 144 students engaged on their tasks of practical exercise. And the following results were obtained : The decreases of I.Q. was evident as compared to the score obtained at the class room; soon after the embarking of the ship, the students on the deck decreased the score by $7\%$ of what they obtained at the class room while the students in the engine room decreased by $13\%$. The I.Q. was regaining the normal state after three days of embarking seemingly showing the fact that the students became adapted to the noise of the ship, but no remarkable improvement was visible during the period of 3 days to 35 days on the ship. One of the remarkable fact that had not been expected was that the problems for audio discernment was much easily solved in the midst of noise that made oral communication impossible (102 dB) than in the place of noise where conversation was possible(67 dB).

It is urgent to have learning support for children with learning disability according to the survey made by the government educational organization. To this end, we developed a learning support system for children with learning disability. First, the system diagnoses the children with learning disability using a decision tree based on the pre-test results. Secondly, it supports for children with learning disability one of audio-, vision- and tactility-oriented learning types according to the results from the psychological learning style test. Thirdly, one-to-one study is supported for failed students at the achievement test. For the evaluation of the system, the children with disability were divided into an experimental group and a control group and the educational achievement was evaluated. We found that 10% on the average was improved in case that learning was made after the psychological test for learning styles.

The purpose of this study was to identify patients' perceptions of health professionals' unkind behavior and the effects of this unkind behavior using a Phenomenological research methodology. Understanding of this phenomena should enlighten nurses to interaction and relationship problems between patient and health professionals and thus lead to further research toward enhancing these interaction and relationships. The subjects were 40 adult patients hospitalized in a university hospital in Seoul. They were from 20 to 65 yews old and hospitalized at IM, GS, OS, NS, OB /GY ward. Their hospital days were from 4 to 72. Data were collected from July 29 to August 9, 1991 and from January 6 to 17, 1992. The research questions were “What behavior on the part of health professionals you perceive as unkind and what effect does such behavior have in you\ulcorner”. Responses to the non-structured open-ended questions were audio-recorded during the interviews done by two nurses researchers. Data were analyzed using the phenomenological method of Colazzi. The validity was enhanced by confirmation of the analysis by two nursing clinical researchers, and professor of psychology, and philosophy, all knowledgable of phenomenological research. From the protocols, 146 significant statements about unkind behavior were organized into 38 formulating meanings which were then grouped into six clusters of themes. Patients' Perceived health professional' unkind behavior as being cold, insincere, unconcerned, disregardful, lacking in technical skill, and failing to provide a therapeutic environment. From the protocols, 65 significant statements about the influence of such behavior on patient care were organized into 18 formulating meanings which were then grouped into four clusters of themes. Patients perceived these unkind behavior influencing then emotionally, physically and having negative effects on their compliance with medical and nursing care. The study points to the need for health professionals to understand how their behavior may be perceived by their patients as unkind behavior. Patients perceptions of health professionals' unkind behavior may suggest the opposite desire, that professionals have exellent medical knowledge and skill and that they be sincere, concerned, respectful and warm emotionally toward their patients.

This paper proposes a new body-effect compensated switch configuration for low voltage and low distortion switched-capacitor (SC) applications. The proposed circuit allows rail-to-rail switching operation for low voltage SC circuits and has better total harmonic distortion than the conventional bootstrapped circuit by 19 dB. A 2-1 cascaded sigma-delta modulator is provided for performing the high-resolution analog-to-digital conversion on audio codec in a communication transceiver. An experimental prototype for a single-stage folded-cascode operational amplifier (opamp) and a 2-1 cascaded sigma-delta modulator has been implemented m a 0.25 micron double-poly, triple-metal standard CMOS process with 2.7 V of supply voltage. The 1% settling time of the opamp is measured to be 560 ns with load capacitance of 16 pF. The experimental testing of the sigma-delta modulator with bit-stream inspection and analog spectrum analyzing plot is performed. The die size is $1.9{\times}1.5\;mm$.

Digital watermarking is to embed imperceptible mark into image, video, audio, and text data to prevent the illegal copy of multimedia data. arbitrary modification, and also illegal sales of the copies without agreement of copyright ownership. In this paper, we study for the embedding and extraction of watermark key using wavelet in the luminance signal in order to implement the system to protect the copyright for image MPEG. First, the original image is analyzed into frequency domain by discrete wavelet transform. The RSA(Rivest, Shamir, Aldeman) public key of the coded target is RUN parameter of VLD(variable length coding). Because the high relationship among the adjacent RUN parameters effect the whole image, it prevents non-authorizer not to possess private key from behaving illegally. The Results show that the proposed method provides better moving picture and the distortion more key of insert than direct coded method on low-frequency domain based DCT.

Recently the multimedia streaming traffic such as digital audio and video in the Internet has increased tremendously. Unlike TCP, the UDP protocol, which has been used to transmit streaming traffic through the Internet, does not apply any congestion control mechanism to regulate the data flow through the shared network. If this trend is let go unchecked, these traffic will effect the performance of TCP, which is used to transport data traffic, and may lead to congestion collapse of the Internet. To avoid any adverse effort on the current Internet functionality, A study on a new protocol of modification or addition of some functionality to existing transport protocol for transmitting streaming traffic in the Internet is needed. TCP-frienly congestion control mechanism is classified with window-based congestion control scheme and rate-based congestion control scheme. In this paper, we propose an algorithm for improving the transmitting rate on a hybrid TCP-friendly congestion control scheme combined with widow-based and rate-based congestion control for multimedia streaming in the internet.
