Change in Quality properties of the Kochujang Prepared with the powder of Paecilomyces japonica and extract of p. japonica by different solvents were investigated during 90 days of fermentation at 20$^{\circ}C$. The moisture content was not significantly different, pH of Kochuiang made with p. japonica was lower than control group and decreased continuously according to the fermentation time. Amino nitrogen continuously increased till 60 days and decreased slightly on 90 days. Amino nitrogen of Kochujang made with P. japonica was higher than control group and was highest on 30 days and 60 days by 179.2mg% and 282.2mg% respectively. Value of L, a, b in Color decreased with proportion to fermentation period and L, a, b value of Kochujang made with P. japonica was lower and in particular that of Kochujang made with P. japonica powder was lowest. from the result of sensory evaluation test, the color of control group was similar to“clear red”but that of Kochojang made with powder of P. japonica was close to“dark reddish brown”and that of Kochujang made with extract of P. japonica was darker than that of control group and the preference of dark color was low. Texture was“glossy and smooth”in all and preference was high. In salty taste, the Kochujang by P. japonica addition was stronger and Kochujang made with extract was stronger than that made with powder. In hot taste, the Kochujang made with P. japonica was weaker than control group and the Kochujang made with P. japonica was scored higher in flavor than control group and Kochujang made with powder of P. japonica was the highest in score. In overall preference, the Kochujang made with P. japonica was better than control group like the result of flavor but expecially Kochujang made with water extract of P. japonica among the extract was best one unlike the result of flavor.

This study was conducted with a non-equivalent control group experimental design to investigate the effects of a video-based infection control program through the application of the social cognitive theory on caregivers. Forty-six caregivers were recruited, with 23 pairs being randomly assigned to the control and experimental groups each. While the experimental group took part in the video-based education, the control group was involved in typical lectures. For two weeks, both groups were educated on the principles of infection control, medical and external handwashing, standard precautions, and quarantine. Their knowledge, performance, and self-efficacy were evaluated before and after the program. There was a significant increase in knowledge (p<.001 and p=.005) and infection control performance (p<.001) in the experimental and control groups. Similarly, self-efficacy, self-regulatory efficacy, task-difficulty preference and confidence significantly increased in the experimental group (p<.001). In the control group, only task-difficulty preference significantly increased (p=.005). Consequently, the online video-based infection control education program applying the social cognitive theory proved effective in improving the caregivers' knowledge and performance in infection control, and their self-efficacy. We suggest the use of this program in effective infection control education for caregivers in the future.

The effect of the addition of dietary fiber extracted from wheat, bamboo, and oat on the quality of fried pork loin batter was investigated. Quality evaluation included proximate composition, pH, color, viscosity, coating and frying yield, electronic nose, and sensory evaluation. Regarding proximate composition of fried batter and fried pork loin, the water content of the dietary fiber treatments was significantly higher than that of the control (p < 0.05), whereas fat content was significantly lower than that of the control (p < 0.05). The lightness of non-fried batter with dietary fiber treatments was significantly higher than that of the control (p < 0.05), whereas the yellowness was significantly lower than that of the control (p < 0.05). The lightness, redness, and yellowness of fried pork loin with dietary fiber treatment were significantly lower than those of the control (p < 0.05). The viscosity and coating and frying yield of dietary fiber treatments were significantly higher than those of the control (p < 0.05). The volatile compounds of dietary fiber treatments were decreased "tallowy" flavor and increased "buttery" and "milky" flavor. The principal components of bamboo and oat fiber treatments were clearly distinguishable from those of the control; however, similar principal components as those of the control were obtained with wheat fiber treatment. Regarding sensory evaluation, the color, texture, and overall acceptability of wheat and oat fiber treatments were significantly higher than those of the control (p < 0.05), and the flavor of the wheat fiber treatment was significantly higher than that of the control (p < 0.05). These results show that wheat and oat fibers are suitable for fried pork loin batter and improve its quality.

There are lots of wired and wireless home network technologies these days. However, an effective middleware is needed to control devices in home regardless oj any kinds of home network technologies applied. We can integrally and simply control all the home appliances using the architecture that leverages TCP/IP and Web technologies, which is like UPnP control technology. In this paper, UPnP technology and IEEE 1394 technology are introduced., and also UPnP over 1394 is issued. Some results from the implementation show that it is possible to control IEEE 1394 devices using the IP-based UPnP technology instead of just using a direct AV/C command set. So, in the experiment, implements the modeling of the UPnP-enabled IEEE 1394 device which is not present for real. Therefore, promising ...

Speech intelligibility in patients with complete dentures is an important clinical problem depending on the material used. The objective of this study was to investigate the speech of two edentulous subjects fitted with a complete maxillary prosthesis made of two different palatal materials: chrome-cobalt alloy and acrylic resin. Three patients with complete dentures in the experiment group and ten people in the controls groups participated in the experiment. CSL, Visi-Pitch were used to measure speech characteristics. The test words consisted of a simple vowel /e/, meaningless three syllabic words containing fricative, affricated and stops sounds, and sustained fricative sounds /s/ and /$\int$/. The analysis speech parameters were vowel and lateral formants, VOT, sound durations, sound pressure level and fricative frequency. Data analysis was conducted by a series of paired T-test. The findings like the following: (1) Vowel formant one of patients with complete denture is higher than that of the control group (p<0.05), while lateral formant three of patients with complete denture is lower than that of the control group (p<0.0l). (2) Patients with complete denture produced lower speech intelligibility with low fricative frequency (/$\int$/) than control group (p<0.0). The speech intelligibility of patients with metal prosthesis was higher than that of those with resin prosthesis (p<0.05). (3) Fricative, lateral and stop sound durations of patients with complete denture were longer than those of the control group (p<0.01 and p<0.05), respectively. Total sound durations of patients with metal prosthesis were similar to that of the control group (p<0.05), while those with resin prosthesis had a shorter duration (p<0.01). This implied that those with metal prosthesis had higher speech intelligibility than those with resin prosthesis. (4) Patients with complete denture had higher sound pressure levels /t/ and /c/ than the control group (p<0.01). However, sound pressure levels for /c/ of patients with metal prosthesis or resin prosthesis was similar to the control group (p<0.05). (5) Patients with complete denture had higher fundamental frequency than the control group (p<0.01).

This study was conducted to develop an automatic nutrient-solution control system for small-scale growers. The nutrient-solution control system consisted of a low-cost and precise metering device and a personal computer. The system controlled electric conductivity(EC) and pH of nutrient-solution based on the time-based feedback control method with the information about temperature, EC, and pH of the nutrient-soIution. The performance of the nutrient-solution control system was evaluated through the control of EC and pH while compared with those of commercial nutrient-solution control system. Also an experimental cultivation of tomato was conducted to verify and to improve the developed system. Results of this study were as follows. 1. An automatic nutrient-solution control system based on a low-cost and precise metering device was developed. 2. The developed system controlled EC and pH within $\pm$0.05 mS/cm and $\pm$0.2 pH full scale error respectively at $24^{/circ}C$. 3. When using the commercial system, the controlled values of EC and pH of the 500l of water were 1.29 mS/cm and 6.1 pH for the setting points of 1.4 mS/cm and 6.0 pH respectively at $22^{/circ}C$. 4. The developed nutrient-solution control system showed $\pm$0.05 mS/cm of deviation from the setting EC value over the experimental cultivation period. 5. The deviation from the average values of Ca and Mg mass content in the several nutrient-solution were 0.5% and 1.8% respectively.
