The objectives of this review are to be aware of the differences between the smear-ripened and mold-ripened cheeses and to compare the sensory attributes of smear-ripened and blue-vein cheeses. Sensory attributes of cheese occupy a prominent place for the desirable overall quality of smear-ripened and blue-vein cheeses. Smear-ripened cheeses characterized by a smooth and brittle texture. Furthermore, smear-ripened cheeses have common grittiness characteristics, also slightly salty and sour flavor compared to blue-vein cheeses. Blue-vein cheeses are characterized by a softer, creamy texture and stronger smells when goat milk is used. Blue-vein cheeses have a fresh, clean, somewhat salty and acid with a slightly bitter tastes compared to smear-ripened cheeses. Finally, the differences in sensory attributes of smear-ripened and blue-vein cheeses such as texture, aroma, and flavor, can make them useful to determine the quality of cheeses.

Purpose: The purpose of this study was to identify the prevalence of irritable bowel syndrome and factors related to irritable bowel syndrome (IBS) in university students. Methods: A cross-sectional, descriptive study was conducted using a self-report structured questionnaire with 420 university students. Data collection was done during May and June, 2017. The data were analyzed using descriptive statistics, a t-test, $x^2$ test, and binary logistic regression analysis with IBM SPSS/WIN 22.0 program. Results: The prevalence for IBS was 24% among Korean university students. Family history of IBS (OR=2.98, 95% CI=1.32~6.70), history of stomach and intestinal disease (OR=2.24, 95% CI=1.36~3.77), sleep quality (OR=2.01, 95% CI=1.16~3.48), mild anxiety (OR=2.75, 95% CI=1.19~6.33) and more than moderate anxiety (OR=2.02, 95% CI=1.02~4.00) were found to be factors related to IBS. Conclusion: The prevalence of IBS was high among university students, and sleep quality and anxiety significantly influenced prevalence of IBS in these students. Therefore, interventions to decrease symptom of IBS must focus on management of sleep quality and anxiety.

This thesis is about the study of inverter terminal boxes in a explosion proof type exhaust fan that can control wind volume and operating time. In Korea, there is no ventilator to adjust the amount of wind and operating time when working in poor conditions. The purpose of the project is to create a explosion terminal box that can control the operating time and wind speed of a suitable explosion ventilator in hazardous environments. The two explosion-proof switches allow the operation time to be driven 1 hour, 3 hours and continuous time, and the speed of the induction motor rotation was set in 3 stages at 2000 rpm, 2600 rpm and 3000 rpm to control the volume. The tested motor used a half-horsepower barrier three-phase induction motor and a full-bridge inverter to set the desired flow rate and operating time.

Surface activities including CMC, surface tension, foaming power etc. of the rhamnolipid (RL), a biosurfactant fermented by microorganism were investigated. Both the RL and liquid detergent contained RL showed a good surface activity. For the detergency test, the liquid detergent with RL showed a slightly better performance than that of using an fatty acid. However for the foaming profile, the liquid detergent with RL exhibited a lot of foam volume and the suppression of the rinsing and foaming during rinsing cycles with the RL was not seen. Therefore it can be concluded that RL can be used as a main surfactant or co-surfactant in liquid detergents without functions of foaming suppression or rinse-aid.

As the performance of engines improves, the temperature of engines is increasing, resulting in a high piston temperature. An excessively high piston temperature may result in torque drop or engine failure. An oil jet is used to reduce the piston temperature. In this study, to monitor the effect of oil jet, a templug was used to measure the piston temperature. A templug is a kind of sensor and the hardness of the templug changes according to the piston temperature. Using a templug, the maximum temperature of the piston was measured with and without an oil jet. The piston temperature was lowered using the oil jet. The highest temperature region changed from the center crown to the front/rear area. In addition, the temperature difference between the highest and lowest regions became smaller.
