Objectives: The aim of this study is to evaluate promotional Internet health information on health functional foods with regard to labeling information, website structure, and overall quality. Methods : The websites of 15 producers of three health functional foods (Red ginseng, vitamin, aloe) were selected. Ministry of Food and Drug Safety (MFDS) required labeling information was used to evaluate the integrity of basic information, and the structural properties of the websites were investigated. Moreover, DISCERN instrument was used to evaluate reliability and quality of information. Results : 1) Among MFDS required labeling information, seven items, including 'sell by date', and 'possible side effects' were not fully specified, and only 6.7% of Internet advertisements provided 'possible side effects'. 2) Each of 92.9% of these websites offered 'Introducation to websites and producers', and 'customer service', whereas only 64.3% and 42.9% of these websites offered 'FAQ about website utilization' and 'multilingual support', respectively. 3) The evaluation using DISCERN instrument showed the scores of $2.03{\pm}0.24$ in reliability, $1.87{\pm}0.28$ in quality, and $2.10{\pm}0.55$ in overall quality. Conclusions : Current promotional Internet health information on health functional foods has various weaknesses in terms of reliability and quality that need to be improved.

The purpose of this study is to evaluate the accessibility of the Cakewalk SI-Drum for the screen reader users. An evaluation was performed by testing the accessibility of the [Virtual Instrument Editing] that is a part of MIDI Production of the NCS(National Competency Standards) by using the SI-Drum and the Sense Reader. The results of this study are as follows. The SI-Drum has almost no basic accessibility for the screen users to do an above task. But the screen reader users can perform the tasks by using Sense Reader's Mouse Pointer function and Position Memory function. To use SI-Drum more efficiently, SI-Drum's basic accessibility have to be provided fully. Several suggestions are proposed to develop a fully accessible SI-Drum for the screen users.

The purpose of this study is to evaluate the accessibility of the SI-Bass Guitar for the visually impaired who uses the Sense Reader which is a screen reader software. An evaluation was performed for the Sense Reader users to do the [Virtual Instrument Editing] task on the NCS(National Competency Standards) using the SI-Bass Guitar. This study shows that the SI-Bass Guitar has no basic accessibility. But the visually impaired can do above task using the Sense Reader's Mouse Pointer and Position Memory Function. Several Propositions are suggested to develop a fully accessible SI-Bass Guitar for the screen users.

Purpose: Determination of the importance values of quality attributes is very important to integrate the Kano model with QFD. A new method to determine the importance values of quality attributes is proposed. Methods: ASC(Average Satisfaction Coefficient) is proposed in order to determine the importance values of quality attributes. To evaluate the effectiveness of ASC, a case study of modern TV sets is conducted, and the performance of ASC is compared with direct importance evaluation and AHP pairwise comparisons. Results: The result of ASC application is similar with those of direct importance evaluation and AHP pairwise comparison. Conclusion: ASC is an effective instrument to determine the importance values of quality attributes. It doesn't need a cumbersome process like AHP pairwise comparison, and can be calculated using the data for the conventional Kano model.

It is very important to have a satisfactory measurement system, since it is useless to try to improve the manufacturing process without an adequate measurement system. Therefore, evaluation of the measurement system is the first step for the quality improvement of the manufacturing process. To estimate the measurement error we must conduct a controlled gage repeatability and reproducibility(gage R&R) study. Many manufacturers use a gage or instrument to measure multiple dimensions for the overall quality of the manufactured parts. In this case, it is necessary to estimate the gage R&R for multiple dimensions. When a gage measures a large number of dimensions of a part, it is very time-consuming and costly to measure all the dimensions. In this paper we propose the use of the principal component analysis method to identify a few principal components out of the original multivariate measurement capability to explain most of the measurement system variation pattern.

A catchment modelling system is the summation of the numerous hydrologic, hydraulic and other process models necessary to simulate the response of a catchment to a storm event. Differences between the recorded catchment response and that predicted by a catchment modelling system can arise from structural errors within the catchment modelling system, evaluation errors in the control parameters, or measurement errors in the recorded data being used to assess the reliability of the evaluation of the control parameters. Presented herein is an investigation of the potential measurement errors within the recorded information, which was considered to occur from instrument error in the ultra sonic flow monitor. This investigation was undertaken using three available rating curves at the Musgrave Avenue Stormwater System in Centennial Park, Sydney, developed by Abustan (1997), Water Board (1994), and using Manning's equation.

The purpose of this study was to evaluation of science curriculum by the cognitive preference construct, the instrument of emotional domain. The effects of students' variables on the cognitive preference were also examined. Samples of 216 boys and 166 girls for this study were selected from the secondary school students. he data were analyzed by ANOVA, Pearson correlation, factor analysis, etc. The results of this study are as follows: (1) The students prefer the Principles of science than any other kind of cognitive preference. (2) Sex has influence on the tendency of students' cognitive preference among the studnets' variables. (3) It is not significantly different the tendency of student's cognitive preference according to IQ among the studnets' variables. (4) Most of the students avoid Critical Questions and Applications of cognitive preference in spite of the difference of sex, grade, and department of the students.

This study is on the fire resistance evaluation method, expecially on the toxicity of smoke gases generated from the fire, of materials for railway car and structures. Until now, Although international standard related to the quantifying evaluation method of smoke gas is provided but the specific procedure is not contained. On this reason, Test results of toxicity show deviation with the different technique being applied. For now, In advanced railway country, various instrument, like ion chromatography and etc., is used but FT-IR is recommended due to its lots of advantages. while FT-IR has a lot of strong points but still has some problems like water vapor interferences. In this paper, To improve credibility and repeatability of FT-IR it contains some technical solutions in quantifying the 8 toxic components.

The fire event occurred in fire proof zone often causes serious electrical problems such as shorts, ground faults, or open circuits in nuclear power plants. These would be directed to the loss of safe shutdown capabilities performed by safety related systems and equipments. The fire event can treat the basic design principle that safety systems should keep their functions with redundancy and independency. In case of a multi-core cable fire, operators can not perform their mission properly and can misjudge the situation because of spurious operation, wrong indication or instrument. These would deteriorate the plant capabilities of safety shutdown and make disastrous conditions. In this paper, the characteristic of cable fire is investigated and the heat-flux evaluation for cable fire is studied. Moreover, a diagnostic methodology for degraded cable in nuclear power plants is presented.
