The purpose of the study 1 is to study the influence of the positive/negative ratio of consumer reviews (3:1, 2:2, 1:3) on consumer's product liking and purchase intention, then to examine the moderator of price (high price vs. low price). The results of the experiment show that when price is high, the ratio of consumers' review is 3:1 can raise the consumers' product liking and purchase intentions. The ratio of positive/negative consumers' review is 1:3 can reduce the product liking and purchase intentions. The study 2 is to examine the impact of existence of consumer reviews which includes three conditions (one positive review, one negative review and no review at all) on consumer perceived risk and purchase intentions, then to examine the moderator of product knowledge (high vs. low). The result support the moderating effects of product knowledge on the consumers' review and perceived risk and purchase intentions.Microcontroller ? Based Embedded System for Drowsiness Detection and Vibration Alertness is a prototype that helps in indicating an individual who has the signs of drowsiness. The purpose of this study is to design and develop a microcontrollerbased embedded system that can detect drowsiness and that can alert the nurses through vibration alertness. Shift workers like nurses often have the tendency to fall asleep thus also showing a lack of energy and a sense of fatigue due to drowsiness during working hours particularly at night or graveyard schedules. According to the proponents’ survey that was conducted for the nurses from Callejo Medical Clinic, 14 out of 15 nurses (93.33%) said that drowsiness affects their duties. This paper aims to develop a proposed study to produce a hardware that consists of a (1) Si1143 Proximity Sensor that would detect the pulse rate of a nurse and an embedded (2) PIC16F689 Microcontroller in which it would process the vibration when the pulse rate drops below its normal condition (i.e. 59 BPM and below). MPLAB X IDE v.3.10 was used as the software for programming, the microcontroller.
