This study examines the effects of a low-calorie raw juice diet on the level of serum ferritin in adults and analyzes nutrient intake from the diet. There were significant differences between juices; the highest calorie was provided by pear juice, highest crude protein, vitamin A, and vitamin B2 levels were from green Juice 1; and highest vitamin C and vitamin B1 levels were from fruit juices. The ratio of estimated energy requirements (EER) for the participants was 56.2% from the raw juice diet. The percentages of recommended intake (RI) from the raw juice diet of protein (57.9%), dietary fiber (19.1%), niacin (6.2%), calcium (0.1%), and magnesium (0.2%) were lower than 75%. However, those of RI of vitamin A, vitamin B1, vitamin B2, vitamin B6, and vitamin C were 1796.5%, 7481.7%, 1915.5%, 30858.7%, and 7500%, respectively, exceeding the tolerable upper intake level (UL) for vitamin A, vitamin B6, and vitamin C. There were significant decreases in weight, the body mass index (BMI), body fat mass, and skeletal muscle mass in males and females. After the diet program, serum iron and SOD (superoxide dismutase) showed significant decreases, whereas RBC, hemoglobin, hematocrit, and serum ferritin showed significant increases. There were negative correlations between serum ferritin and weight and between serum ferritin and skeletal muscle mass for all participants. There were negative correlations between serum ferritin and skeletal muscle mass for males and between serum ferritin and body fat mass for females. These results suggest that a raw juice diet can supplement a regular diet to prevent excess or deficient nutrient intake.

Sensory factors are important determinants of appetite and food choices but little is known about factors affecting taste acuity and preference of Koreans. Any factors causing deficits in sweet taste perception may lead to over consumption of simple sugar, which is related to several chronic diseases. This study was conducted to determine factors affecting sweet taste sensitivity and preference. Subjects were 30 government employees who were serving as school dietitians or in the area of public health while they were studying in the program for the qualification to become nutrition teachers. Sweet taste threshold and the optimally-preferred sweetness of omija jelly were determined by a sensory evaluation and general characteristics, health-related lifestyles, dietary habits and food preferences were determined using a self-administered questionnaire. For the subjects of this study, detection threshold concentration of sucrose solution was $0.184{\pm}0.06%$ and optimally-preferred sucrose concentration of omija jelly was $13.88{\pm}2.28%$ and there was no significant correlation between the sweet taste sensitivity and preference. Subjects who had higher(${\ge}4$ out of 10) physical or psychological stress and who had late getting-up time (after 7am) tended to have lower sweet taste threshold (higher sensitivity) than their counterpart. The sweet taste preference determined by optimally-preferred sucrose concentration of omija jelly tended to be lower in the subjects who eat slowly. Those who answered in the questionnaire to prefer sweet foods did have significantly higher optimally-preferred sucrose concentration of omija jelly. Further research is required to determine whether decreased sensitivity and increased preference for sweetness can increase the actual intake of simple sugar.

Purpose: Ketamine has historically been contraindicated in traumatic brain injury (TBI) due to concern for raising intracranial pressure. However, it is increasingly being used in TBI due to the favorable respiratory and hemodynamic properties. To date, no studies have evaluated whether ketamine administered in subjects with TBI is associated with patient survival or disability. Methods: We performed a retrospective analysis of data from the multicenter Prehospital Tranexamic Acid Use for Traumatic Brain Injury trial, comparing ketamine-exposed and ketamine-unexposed TBI subjects to determine whether an association exists between ketamine administration and mortality, as well as secondary outcome measures. Results: We analyzed 841 eligible subjects from the original study, of which 131 (15.5%) received ketamine. Ketamine-exposed subjects were younger (37.3±16.9 years vs. 42.0±18.6 years, P=0.037), had a worse initial Glasgow Coma Scale score (7±3 vs. 8±4, P=0.003), and were more likely to be intubated than ketamine-unexposed subjects (88.5% vs. 44.2%, P<0.001). Overall, there was no difference in mortality (12.2% vs. 15.5%, P=0.391) or disability measures between groups. Ketamine-exposed subjects had significantly fewer instances of elevated intracranial pressure (ICP) compared to ketamine-unexposed subjects (56.3% vs. 82.3%, P=0.048). In the very rare outcomes of cardiac events and seizure activity, seizure activity was statistically more likely in ketamine-exposed subjects (3.1% vs. 1.0%, P=0.010). In the intracranial hemorrhage subgroup, cardiac events were more likely in ketamine-exposed subjects (2.3% vs. 0.2%, P=0.025). Ketamine exposure was associated with a smaller increase in TBI protein biomarker concentrations. Conclusions: Ketamine administration was not associated with worse survival or disability despite being administered to more severely injured subjects. Ketamine exposure was associated with reduced elevations of ICP, more instances of seizure activity, and lower concentrations of TBI protein biomarkers.

The 3 year graduate school course of the dental technician, which has been enforced since 1994 till the present date, differs from the currently existing 2 year graduate course because of an 8 weeks clinical field training course being newly executed and an imposed curriculum about manufacturing specialized prosthetics like all-ceramic, double prosthetic technology, attachment, and implant. Even though nearly 10 years have passed, the education program of the 18 colleges have still not been standardized and the subjects differing a little, while some are still not following the 3 years graduate course. The goal of this research is to emphasize the qualities of the 3 years graduate program and enable the dental technician to handle clinical models in the dental technical clinic right after graduation by adding clinical field training in the dental technician education program of the 18 colleges. Also in accordance to a national and international increase in esthetical prosthetics, credits, weekly study hours, education practice time of specialized prosthetic dental technology can be analyzed as follows. 1. In the year 2003, currently colleges start clinical practice education starting from the 1st semester of the 2nd year junior year, to the 2nd semester of 3rd year the varying in time with adequate class time, and credits. The average credit is 9.56, and weekly average class time is 18.00 hours. later clinical trainee education will be adjusted to the 3 year graduate school course to 10 credits and 20 hours and the adequate education period should be the 2nd semester of 3rd grade when most basic clinical education has been covered. 2. Currently in the year 2003, all-ceramic education has an average credit of 8.01 in 17 colleges with an exception of Ma-san college. The weekly average theoretical education is 4.94 hours, weekly clinical education of 7.88 hours and currently in 14 colleges porcelain technical class usually starts in the 1st semester of the 2nd year. All-ceramic education is thought to have adequate credits, timing, and weekly study hours. 3. Currently in 2003 implant education is enforced in 11 colleges including Bu-san Catholic university and the education period is usually in the 3rd year. Out of the 11 colleges, only Bu-san Catholic univ., Ma-san and Shinheung college have practice training classes. We knew that Shingu, Dongu, Mokpo science colleges have practice training as a curriculum, namely specific prosthetics laboratory. Out of the 9 colleges enforcing implant education the average credits taken are 2.56, and the average hours of weekly theory education is 2.14, but with the exception of Shinheung college which has an implant practice training course theory and practice classes are not divided. Therefore implant education is thought to start in the 3rd year as a 3 credit course with 3 hours of theory and practice each. 4. Currently in 2003, theoretical attachment education is given in 15 colleges and including practical training it is given in 10 colleges. The education starts 1st semester of the 2nd year till the 2nd semester of the 3rd year. The average credit of attachment theory education in the 15 colleges was 3.64, the average weekly theoretical education was 2.64, and the average weekly practice training out of the schools teaching it was 3.20. Later attachment education is thought to start the 1st semester of the 3rd year as a 3 credit course with 2 hours of theory class and 3 hours of practice training. 5. Double prosthetic technology is currently carried out in Dae-jon Health Science college(2nd year 2nd semester, 2 credits, theory 2hours), Gimcheon college (1 credit, 2 hours of practical training), Bu-san Catholic university (4th year 2nd semester, 4 hours of theory. practice). When the 3 year course is enforced, education will start 1st semester of the 3rd year with 2hours of theory and practice each. 6. The newly installed programs of the 3 year education is clinical field training, and specialized prosthetic manufacturing practice like all-ceramic, double prosthetic technology, attachment, and implant. If such education is to be effectively managed, a primary precursor as systemic basic clinical education is thought to be important. 7. Nationally in the 18 colleges of dental technology the currently executed curriculum course had varying subjects, class time according to the subject, and credits by each college. The curriculum difference between the colleges must be settled.

Purpose: This study aimed to develop the protocol of kangaroo care for premature infants and to evaluate its effects including physiologic responses of premature infants, their parents'anxiety, and neonatal nurses'perception regarding the kangaroo care. Methods: Kangaroo care protocol was developed through a literature review and validation of an expert group. The developed kangaroo care protocol was tested with 27 preterm infants, 24 parents, and 60 nurses in one neonatal intensive care unit in S hospital. Data were collected from December 2012 to February 2013 and analyzed by descriptive statistics and t-test using the SPSS/Win statistical program. Results: Physiologic responses including heart rate, respiration rate, oxygen saturation, body temperature among premature infants received the kangaroo care were maintained within normal limit. The anxiety levels of the parents who provided kangaroo care for their infants were significantly decreased as it was compared before and after care (t=3.43, p=.002). There were no significant differences in nurses'perceptions about kangaroo care before and after the application of the protocol. Conclusion: The developed kangaroo care protocol is proved to be effective and can be used safely in nursing practice.

This study was designed to verify the effect of aromatherapy on menstrual cramps and dysmenorrhea by a quasi experiment (nonequivalent control group pretest-posttest design), from March to October, 2000. The subjects of this experiment consisted of 45 college women with menstrual cramps and dysmenorrhea. They were randomized by 25 for the experimental group and 20 for the control group. Their mean age was 20.6 years, mean menstrual period 28.7 days, mean menstrual cramps(VAS) 7.25, mean dysmenorrhea (Dysmenorrhea Scale) was 27.34. As treatment, aromatherapy was to give effleurrage of the abdomen with lavender, clary sage and rose as aroma oil, almond oil as carrier oil. For the control group, abdominal massage was given with only almond oil. Data collection included menstrual cramps, dysmenorrhea, the change of symptoms(low abdominal pain, lumbago, headache, nausea, fatigue, edema). Menstrual cramps, dysmenorrhea and general, menstrual characteristics of subjects were measured the first day of the pre menstrual period before treatment (pre-test), menstrual cramps, dysmenorrhea, the change of symptoms were measured the first and second day of post menstrual period after treatment (posttest). Data were analyzed by t-test, $\chi^2$- test, repeated measures ANOVA, Cronbach's ${\alpha}$ with SAS Program. The results of this study was as follows; 1. Menstrual cramps was significantly lower in the experimental group(p = .001). 2. Dysmenorrhea was significantly lower in the experimental group(p = .027). 3. Less women in the experimental group complained about the six symptoms than women in the control group after treatment on the first day of the menstrual period(p < 0.05, p < 0.01) In conclusion, these findings indicate that aromatherapy with lavender, clary sage, and rose could be effective to decrease menstrual cramps, and dysmenorrhea. So, aromatherapy could be applied to women suffering with menstrual cramps, dysmenorrhea periodically as an nursing intervention.

In digital TV broadcasting, such as terrestrial, cable, satellite, and IPTV, the head-end of digital TV broadcasting has a more complicated transmission structure than that of analog TV broadcasting. Furthermore, digital TV broadcasting has a feature that supports multiplex models, such as Multiple Program Transport Stream (MPTS). Therefore, the purpose of our work was to design and examine a more efficient new system of emergency alert message transmission to support the digital TV broadcasting environments. Digital TV broadcasting is the IP generation or RF transmission of 8-VSB, QAM, and QPSK modulated through a multiplexer or re-multiplexer multiplexed stream as a MPEG-2 Transport Stream after content encoding. The new system proposed in this paper transmits an emergency alert message without scrambling after replacing the PID and payload of the -packet with the message prototype in the TS stream from the multiplexer. If we need to transmit an emergency alert message under digital TV broadcasting services, then the receiver first checks the PID of each packet in the TS stream for the emergency alert message. Next, if a packet is determined to be an emergency alert message, then the set-top box displays the message on the TV screen using its function of On Screen Display, or the PC based software displays the message on the monitor screen using its function of overlay with user interface if the packet is found to be an emergency alert message. We have designed an emergency alert message protocol and a system model. By experiments and analysis of the system, we concluded that the system achieved efficiency and the ability to send and receive emergency alert messages using the system under different digital TV broadcasting service environments.
