Owing to recent advanced techniques in information and communication technology(ICT), our daily life has been changing very quickly and our life style has also been affected greatly. In the current knowledge and information society, the disabled can have a right to enjoy benefits of advanced ICT technologies. However, there is a barrier called digital divide so that the disabled have some difficulties to communicate to the world with ICT technologies. In this sense, our job is to close digital divide and let the disabled enjoy benefits of ICT technologies. Recently there have been some research works to close digital divide between the disabled and the non-disabled. Among various attempts to close digital divide, improving web accessibility for the disabled is the biggest concern since web is a still representative tool among ICT tools. The purpose of this paper is to propose some practical guidelines for improving web accessibility for the disabled. The proposed improvement guidelines are developed based on the existing web accessibility guidelines and are upgraded for more adaptable to the disabled. Our principles are based on the following philosophy. First, any input transmission must be more confirmed. Second, prevent any instant request. Third, allow the disabled to record or store the contents if necessary. Fourth, reduce physical movement for the disabled. Fifth, provide more interaction tools for the disabled.

This study was conducted to establish a method to analyze azodicarbonamide (ADA) in wheat flour. A new method using high performance liquid chromatography (HPLC) was developed for the determination of ADA in wheat flour. The recovery rate was 91.93~97.54%. The limit of detection for ADA was 0.02 mg/kg and the limit of quantification was 0.05 mg/kg. The monitoring results for ADA contents using the established methods showed that it was detected as the low value of 0.95 mg/kg in one of 51 flour samples (detection rate : 2%), but not detected in 59 bakery samples. The detected ADA level was suitable to its usage standard, compared to the standard (45 mg/kg). Although the detection rate was very low, the established analytical method of ADA will contribute to the management of ADA in processed foods such as wheat flour and bakery.

This study was investigated on the antitumor of protein-polysaccharide fraction(PPF) extracted from seaweeds such as sea-staghorn and laver toward sarcoma-180 cells. In the PPF extracted from these sewaweeds, the polysaccharide contents of sea-staghorn and laver were $62.26\%$ and $65.78\%$, respectively. The highest levels of polysaccharides found in seaweeds was fructose. The major amino acids were aspartic acid, glutamic acid, glycine and cystein. The solid tumor growth inhibition showed the highest level of $53.30\%$ when 50mg/kg sea-staghorn was administrated. The life prolongation effect was $17.35\%$ at 50 mg/kg of laver. In the effects of immunologic activity, when 100mg/kg sea-staghorn was administrated, the number of circulating leucocyte showed the highest level of $82.23\%$ but decreased leucocyte for prolonged times. The number of total peritoneal exudate cells of the sea-staghorn administerated group was increased significantly in comparison with the control group. The hematobiolgoical analysis of the experimental group was similar with that of the control group. This experiments indicated that hemeastasis still maintained nor-mal state and not showed any harmful effects in normal mice.

To develop an effective use for poor-quality individually quick-frozen (IQF) oysters Crassostrea gigas stored for a long period, the extract conditions, quality characteristics, and optimum reaction flavoring (RF) conditions of a complex extract from these IQF oysters were investigated. The moisture, pH, and volatile basic nitrogen contents of IQF oysters stored for 18 months (18M-IQFO) were 77.9%, 6.32, and 17.9 mg/100 g, respectively. Three different kinds of extract were prepared from 18M-IQFO: a hot-water extract (HE), scrap enzymatic hydrolysate (EH), and complex extract (CE). The respective extracts contained 5.5, 8.6, and 6.6% crude protein and 281.7, 366.0, and 343.0 mg/100 g amino nitrogen, and had 811, 359, and 1,170 mL/kg extraction yields. The CE was superior to the traditional HE in terms of the extraction yield, amino-nitrogen content, and organoleptic qualities, except for the odor. To improve flavor via the Maillard reaction, the reaction system used to produce a desirable flavor comprised CE (Brix $30^{\circ}$), 0.4 M glucose, 0.4 M glycine, and 0.4 M cysteine solution (4:2:1:1, v/v). The reaction time and pH were the independent variables, and the sensory scores for baked potato odor, masking shellfish odor, and boiled meat odor were the dependent variables. The surface response methodology (RSM) analysis of the multiple responses optimization gave a reaction time of 120.6 minutes and pH 7.33 at $120^{\circ}C$. The reaction improved the flavor of CE considerably, as compared to that of the unreacted extract.

Organizational factors and personal traits are two elements of widely acknowledged relevance in employees' organizational outcomes in hotel industry. Personal traits especially need to be further examined as a consideration for employment. As one of the personal traits that provide capability to manage emotions, emotional intelligence is selected. The empirical objective of this study is to investigate the effects of emotional intelligence on job satisfaction and organizational commitment in a structural model. To conduct research questions, five star deluxe hotel employees in Korea are targeted to be surveyed. Descriptive statistics and multivariate analysis of variance, and structural equation modeling(SEM) are utilized employing SPSS and AMOS 4.0 to analyze the survey results. It was found that the components of perceiving emotions and understanding emotions predicted job satisfaction. Relatively perceiving emotions presented a higher impact on each dimension of job satisfaction. Satisfaction with co-workers and communication can also explain the level of hotel employees' organizational commitment. Broadly speaking, the results suggest that effective psychotherapeutic or reciprocative programs should be integrated into hotel training contents for emotional intelligence development.

This paper has the objectives to define the concept of 'Good Care' which is the service goal we are aiming essentially for the improvement of long-term care service quality, to find out the components for 'Good Care', and to explore the conditions that create a good care. In addition, we tried to find the answer about what is the best way to measure the service quality. For this, I referred the advanced researches which explored the fundamental properties of care and tried to find the answer from the accumulated wisdom of service field through the 5-year long term care service experience. As a result of research, the good care can be defined as helping someone to be able to maintain his own life as maximum as possible with the goal to assure total quality life. The most important condition for good care is making 'a good care relationship'. Without damaging the relationship between care provider and care receiver, the individualized service focusing on the demand of care receiver based on mutual reliability, mutual respect and smooth communication should be provided. For the evaluation system, it is reasonable to set the standard according to the size of each institution for the core quality of facility service and establish the certification system of absolute standard to carry out the quantitative evaluation rather than the relative evaluation in the whole. For the part over the absolute certification standard, it is reasonable for each institution to characterize its own characteristics autonomously and carry out the qualitative evaluation for this. For the evaluation of home visit care service, it is recommended to contain the evaluation contents such as user satisfaction, satisfaction of care worker, how well the case management system of home care service center is operated etc.

This study investigates the change of chemical components, antioxidant and antimutagenic activity in Glycyrrhiza uralensis Fischer stems and leaves (GU) by the various processing methods, as follows: fresh (GU-1), dried under the shade (GU-2), blanched (GU-3), roasted 3 times (GU-4), roasted 4 times (GU-5). The components have been identified and quantified through the use of gas chromatograph-mass spectrometry (GC-MS). At results, cis-1,3-dimethyl-2-methylenecyclohexaneat at 19.7 min and n-hexadecanoic acid at 21.5 min were detected in five kinds of extract. 3-O-Methyl-D-fructose at 17.8 min was observed in four extracts except in GU-1 and aminopyrazine at 19.8min was observed in four extracts except in GU-4. The total phenolics contents was high in GU-4(3.38 g/100 g). ABTS radical scavenging was high in GU-5($EC_{50}$, 0.57 ug) and DPPH radical scavenging was high in GU-4($EC_{50}$, 2.66 ug). The extracts of GU-3, GU-4, and GU-2 were most potent in anti-mutagenicity activity against 1-NP, Trip-P-1, and Trip-P-2, respectively. GU-3 and GU-4 also showed most potent effect of anti-mutagenicity on 2-AA and AFB1, respectively.
