To measure temperature in microwave heating condition by thermocouple or thermistor is limited. In order to overcome this problem kinetics of ascorbic acid destruction was introduced. Activation energy for destruction of ascorbic acid was obtained under conventional heating condition. Arrehnius equation was used for prediction of rate constant under microwave vacuum heating condition. Then prediction of temperature could be obtained by using kinetic of ascorbic acid destruction that is calulated by the predicted rate constant.

Platelets play an essential role in hemostasis through aggregation and adhesion to vascular injury sites but their unnecessary activation can often lead to thrombotic diseases. Upon exposure to physical or biochemical stimuli, remarkable platelet shape changes precede aggregation or adhesion. Platelets shape changes facilitate the formation and adhesion of platelet aggregates, but are readily reversible in contrast to the irrevocable characteristics of aggregation and adhesion. In this dynamic phenomenon, complex molecular signaling pathways and a host of diverse cytoskeleton proteins are involved. Platelet shape change is easily primed by diverse pro-thrombotic xenobiotics and stimuli, and its inhibition can modulate thrombosis, which can ultimately contribute to the development or prevention of thrombotic diseases. In this review, we discussed the current knowledge on the mechanisms of platelet shape change and also pathological implications and therapeutic opportunities for regulating the related cytoskeleton dynamics.

Objective: This study was carried out to compare changes in pain, swelling and range of motion (ROM) between the two groups according to physical therapy intervention. Design: Randomized controlled trial. Methods: There were a total of 20 elderly subjects ages 65-75 years old who have been admitted to the hospital for a total knee arthroplasty. After surgery, the experimental group (n=10) carried out quadriceps femoris muscle strengthening exercise, hamstring stretching exercises and gastrocnemius stretching exercise with a physical therapist for 30 minutes and additionally, received ice pack therapy for 20 minutes once a day. The control group (n=10) carried out continuous passive motion for 30 minutes and received ice pack therapy for 20 minutes once a day. The experimental group and control group carried out each intervention program for 2 weeks 3 times a week. The Visual Analogue Scale was used to assess pain, tape measurements were taken to assess swelling, and a steel goniometer was used to assess knee joint ROM. Results: As a result, the experimental group showed a statistically significant decrease in the pain and swelling, and a significant increase in knee flexion ROM after the intervention, compared to the control group (p<0.05). There was a significant improvement in pain, edema, and knee flexion and extension ROM in all subjects after intervention (p<0.05). Conclusions: According the results of this study, exercise in the experimental group is effect on the pain, swelling and ROM for total knee arthroplasty.

This study aims to understand some related types (to DiSC behavioral ones) through an analysis about DiSC behavioral types of freshmen at the clinical pathology department in the University. In order to do that, a total of 34 male and female students were surveyed. General characteristics and DiSC behavioral types for the targeted students were analyzed for frequency and percentage. For the frequency, the Chi-square test was performed and the level of significance was set to p<0.05. For the elements to select the university at general characteristics from the result of this study, 21 students were found to have selected the university voluntarily (61.8%). For the information about the clinical pathology department, 14 students were found to be informed through media (41.2%) and 7 students were informed through their parents (20.6%). For the DiSC behavioral types of the students majoring in clinical pathology, 18 students were found to be I type (53.0%), 8 students were C type (23.5%), 5 students were S type (14.7%) and 3 students were D type (8.8%). The relevance between general characteristics and DiSC behavioral type were found to be insignificant. As this study is aimed, there is no significant relevance between general characteristics and DiSC behavioral types, but through an understanding of characteristics of the students majoring in the clinical pathology, helping freshmen who are taking their first steps to adapt themselves to a new environment by diagnosing and understanding their behavioral types, understanding behavioral styles of those four types and guiding them in a positive direction, the method should be considered to raise their satisfaction about the major.

Effect of Post-CMP Cleaning On Electrochemical Characteristics of Cu and Ti in Patterned Wafer
Noh, Kyung-Min,Kim, Eun-Kyung,Lee, Yong-Keun,Sung, Yun-Mo Materials Research Society of Korea 2009 한국재료학회지 Vol.19 No.3
The effects of post-CMP cleaning on the chemical and galvanic corrosion of copper (Cu) and titanium (Ti) were studied in patterned silicon (Si) wafers. First, variation of the corrosion rate was investigated as a function of the concentration of citric acid that was included in both the CMP slurry and the post-CMP solution. The open circuit potential (OCP) of Cu decreased as the citric acid concentration increased. In contrast with Cu, the OCP of titanium (Ti) increased as this concentration increased. The gap in the OCP between Cu and Ti increased as citric acid concentration increased, which increased the galvanic corrosion rate between Cu and Ti. The corrosion rates of Cu showed a linear relationship with the concentrations of citric acid. Second, the effect of Triton X-$100^{(R)}$, a nonionic surfactant, in a post-CMP solution on the electrochemical characteristics of the specimens was also investigated. The OCP of Cu decreased as the surfactant concentration increased. In contrast with Cu, the OCP of Ti increased greatly as this concentration increased. Given that Triton X-$100^{(R)}$ changes its micelle structure according to its concentration in the solution, the corrosion rate of each concentration was tested.
