  • The purpose of this study was to find out the effects of education for prevention of child sexual abuse (rape, sexual assault, sexual harassment etc.) of children in elementary school students. Incidences of sexual abuse in Korea is ranked 3rd in the world. Sexual abuse of children, particularly, is one of the most serious crimes that affect both the victimized children and their family. The issue related to sexual abuse of children has been ignored, and there is a lack of systematic education to prevent sexual abuse of children either for children or their parents. Furthermore, lack of knowledge and poor attitude of teachers limit their capability to provide education for sexual abuse prevention to the children. The education for teachers may change their knowledge of the sexual abuse and their attitude toward it and improve their capability in helping children. 223 Korean elementary school students participated in this study. Research design was One group pretest-posttest design. The education given to the subjects included 4 hours through the multimedia CD-ROM on the prevention of child sexual abuse. The education program was developed based on a survey. School- aged- children, parents, and teachers were interviewed to reveal their educational needs based on their experiences related to sexual abuse. This program includes such as safety education, crisis management, resource person(s), and phone numbers of available hospital. Data was collected before, during and after the education was given to the subjects, to assess their knowledge and attitude toward child sexual abuse. Two instruments were used in this study. Using Cronbach's ALPHA validity and reliability of 2 instruments were tested. The analysis of the data was done with Window SPSS 10.0 for descriptive statistics, t-test and ANOVA. The results of this analysis were as follows : 1. After education, the score of school nurses knowledge was higher than before(t= -4.677, p=0.000). 2. After education, the score of school nurses attitude was not higher than before (t=0.131, p=0.896). The findings from this study will provide an intervention strategy for prevention of sexual abuse in children.

  • Reed-Solomon(RS) codes have been employed to correct burst errors in applications such as CD-ROM, HDTV, ATM and digital VCRs. For the decoding RS codes, the Berlekamp-Massey algorithm, Euclidean algorithm and modified Euclidean algorithm(MEA) have been developed among which the MEA becomes the most popular decoding scheme. We propose an efficient recursive cell architecture suitable for the MEA. The advantages of the proposed scheme are twofold. First, The proposed architecture uses about 25% less clock cycles required in the MEA operation than[1]. Second, the number of recursive MEA cells can be reduced, when the number of clock cycles spent in the MEA operation is larger than code word length n. thereby buffer requirement for the received words can be reduced. For demonstration, the MEA circurity for (128,124) RS code have been described and the MEA operation is verified through VHDL.

  • In order to read correct data from a disk-type holographic storage medium, it is very important to implement a servo-control in the pick-up module, as in a conventional CD-ROM. We propose a novel servo-control method using a glass plate on the optical axis, which is able to compensate the mechanical errors coming from wobbling of holographic disk and spindle motor. By rotating the glass plate within $\pm$10 degrees, we can reduce the reading errors of $\pm$200 ${\mu}{\textrm}{m}$ to $\pm$15 ${\mu}{\textrm}{m}$.

  • The purpose of this study was to study how nurses interpreted the meaning of Hwa-Byung. It was carried through a review of literature, and the result is expected to explore ways that nursing intervention can promote the understanding of Hwa-Byung. The literature review focused on cultural psychology and psychiatrists' views toward Hwa-Byung. After that, it was reconfirmed concept of Hwa-Byung in nursing devived from historical analysis of the examples of Hwa-Byung from a true record of the Cho-Sun Dynasty(CD ROM, 1997). Characteristics of patients with Hwa-Byung include 'Hwa', an aspect of somatization, and self-diagnosing. It also could find that Hwa-Byung is characterized as 'Hwa', 'somatization' and 'self-diagnosis(subjectiveness)' according to a true record of the Cho-Sun Dynasty(CD ROM, 1997). The conceptual definition of 'Hwa', 'somatization' and 'self-diagnosing (subjectiveness)' are as follows. The core concept of Hwa-Byung, 'Hwa,' has the property of 'fire', and equals the feeling of injustice. Hwa-Byung means congestion of 'Hwa'. Therefore Hwa-Byung is the accumulation of being mistreated and mortified. The feeling of mistreatment comes from subjective experiences, which cannot be in harmony with the values, beliefs and rights of the patients. The situations that they have to endure again and again, though they are the sufferers, connote suppressed aggression and powerlessness endured over time. Suppressed aggression subordinated hostility, hatred and revengeful thoughts; powerlessness subordinates frustration, resignation, and fatalism. Somatization is another form of expressing 'Hwa' through physical symptoms. The somatization of clients with Hwa-Byung plays a role in expressing non-verbalized and suppressed emotions within themselves. The clients who experiences Hwa-Byung think that they know the cause of their illness and self-diagnose their problem as Hwa-Byung. Therefore, the feeling of unfairness which is the premise of Hwa-Byung infers 'subjectiveness' In conclusion, nursing's concept of Hwa-Byung is the accumulation of feelings of being mistreated and mortified. Hwa-Byung is the internalized 'Hwa' from enduring again and again. The feeling of being mistreated comes from subjective judgements about unfairness that cannot be harmonized with the clients' values, beliefs and rights. Those who can express their 'Hwa' only through their bodies imply suppressed aggression and powerlessness.

  • Nowadays we usually act based on information in order to act effectively, we should enlarge our access to information of course, we have several methods to choose from, but commercial databases are the most advantageous. One reason is that everyone has equal access to commercial databases. As a result, people or companies who use commercial database information skillfully have a distince advantage over those who don't commercial database services in japan have been changing rapidly since their birth more than twenty years ago. For example, the distribution mode of databases is changing : from the original batch(off line) to on-line and most recently to the coexistence of batch and on line with the advent of CD-ROM. It is important for us to keep up with the new trends in databases, and to utilize them effectively as a tool in the information age.

  • MPEG-2 Advanced Audio Coding (AAC) has already been standardized as a sophisticated next generation technology AAC provides an audio signal that has CD quality at 96-128kbps/stereo. This paper describes a high-quality and efficient software implementation of an MPEG-2 AAC LC Profile encoder. Common scalefactor and noisless coding are accelerated by $45\%$ and $27\%$, respectively, through the use of TMS320C30 instructions. The implemented encoder uses 7.5kWords of program memory, 18kWords of data ROM and 92kBytes of data RAM, respectively. The results of subjective Qualify test showed that the sound quality achieved at 96kbps/stereo was equivalent to that of MP3 at 128kbps/stereo.
