Different studies have been conducted regarding caffeine as psychostimulant drugs and its effects as well as determination in various materials. Since, coffee and tea are most drinkable beverage in the world and their major constituent is caffeine. So, analysis of the effect of equal amount of caffeine in coffee and tea with respect to SD rats was studied. The present methodology was purposed to determine and validate caffeine amount in different brands of coffee and tea, and canvass locomotor and behavioral patterns of SD rats after administrating coffee and tea orally consisting of same amount of caffeine (10, 30 mg/kg). Determination of caffeine in different brands of coffee and tea and validation of caffeine were evaluated using HPLC. Depending upon different brands of tea and coffee, caffeine amount was altered. Meanwhile, amount of caffeine in tea was directly proportional to the temperature of liquid. Coffee and tea (Instant Maxim original coffee$^{(R)}$ and earl grey black tea$^{(R)}$) consisting 10, 30 mg/kg of caffeine were studied in SD rats for locomotor activity and behavioral patterns using Tru Scan 99. The locomotor activities of SD rats were increased after administration of coffee and tea consisting caffeine compared to water. The coffee consisted of higher amount of caffeine exhibited steep movement of SD rats. Similarly, rearing and scratching of SD rats as frequency and duration were increased in coffee and tea consisting caffeine compared with water. The study revealed that coffee and tea had effects in locomotor activity and behavioral patterns of SD rats.

Background and objective: As the agricultural industry becomes a more convergent industry, it is believed that the demand for human resources by companies will change. Therefore, a survey was conducted to investigate the human resources required by agriculture companies. Methods: In the survey on 77 agriculture companies, 98.7% of respondents answered that new employees with a college degree needed additional training to adapt to practical affairs. Results: The first priority of education was "community spirit" (22.1%) and the second priority was "convergence capability" (15.6%). The most important educational goal desired by agricultural companies was "cultivating human resources with community spirit and ethical judgment", followed by "cultivating human resources with serious communication and problem-solving skills", and "cultivating human resources with scientific thinking and unique creative imagination." Sub-competencies that companies want agricultural colleges to strengthen were "community spirit" 4.32(SD=0.96), "desirable values" 4.30 (SD = 1.05), "sympathy" 4.28 (SD = 0.95), "convergence capability" 4.16 (SD = 0.88), "creativity" 4.11 (SD = 0.83), "civic spirit" 4.10 (SD = 0.91), and "rational/critical thinking" 3.94 (SD = 1.04). There was a significant difference in sub-competencies that require reinforcement depending on the number of full-time employees. "Creativity" was most necessary in companies with less than 3 employees (4.39), and 4~7 employees (4.33), and "aesthetics"" in companies with less than 3 employees (3.94), and 4-7 employees (3.61) "Civic spirit" was most necessary in companies with 31 employees or more (4.33). Conclusion: The most important educational goal desired by companies was "cultivating human resources with community spirit and ethical judgment".

This study employed the Semantic Differential(SD) technique for an empirical analysis of the borrowed landscape-the so-called interaction of landscape between space and nature-in traditional Korean space against the cultural backdrop of confucian ideology. Its findings are as follows: First, the study conducted a comparative analysis of the borrowed landscape between Sarangchae(Men's quarters) and Anchae(Women's quarters) and between Soteuldaemun(A lofty gate) and Sadangdaemun(A gate to an ancestral shrine), using the SD technique. Consequently, their marked distinction in the borrowed landscape were found to illustrate the influence of confucian ideology over spatial composition. Second, both the garden and the sky of Sarangchae appeared more open and dynamic, and soft, and comfortable, and warm compared to Anchae. Also, Soteuldaemun looked more open and dynamic than Sadangdaemun. In conclusion, traditional Korean space applies a monistic view of the world to nature and human beings, thereby embodying a philosophical and aesthetic space where humans enjoy their life in harmony with nature while playing with the landscape in a traditional space.

Background: Ketamine has an indirect sympathetic stimulation effect. We investigated heart rate variability (HRV) as a marker of cardiac autonomic function after a target controlled infusion (TCI) of ketamine with a plasma concentration of 30 or 60 ng/ml. Methods: In 20 adult volunteers, the mean of the R wave to the adjacent R wave interval (RRI), the range of RRI, the root mean square successive difference of intervals (RMSSD), the total power, the low frequency (LF, 0.04-0.15 Hz) power, the high frequency (HF, 0.15-0.4 Hz) power, the normal unit HF (nuHF), the normal unit LF (nuLF), the LF/HF ratio and the SD1 and the SD2 in the Poincare plot were measured before and after a TCI of ketamine. We observed for any psychedelic symptoms or sedation. Results: There were no differences in the mean and range of the RRI, RMSSD, total power, LF power, HF power, nuHF, nuLF, LF/HF ratio, SD1 and SD2 between before and after ketamine administration. The OAA/S score was higher and there were more psychedelic symptoms with a 60 ng/ml plasma concentration than with a 30 ng/ml plasma concentration. Conclusions: This study did not show any effect of a low plasma concentration of ketamine on the autonomic nervous system.

In order to provide data basic to the training of hospice volunteers, this study was carried out to investigate the personal attributes and the Death Orientation of hospice volunteers. 80 hospice volunteers were sampled from those registered on Seoul Catholic Social Service and Korean Association for Volunteers Effort conveniently. Data were gathered from August 16th to October 3rd, 1991. The instrument used for this study was the Death Orientation Questionnaire developed by Thorson and Powell, subjective age and religiosity questionnaire developed by Bell and Batterson, and subjective health criteria developed by Baumann. Data were analyzed using frequency, mean, standard deviation, Chi-square, and t-test by SPSS - program. Result of this study are summarized as follows ; 1. The majority of hospice volunteers perceived younger in their subjective age than their chronological age (65%), Perceived themselves to be healthy subjectively(88.8%), and revealed to have high religiosity score(96.3%) 2. Level of Death Orientation of hospice volunteers was revealed to be moderate.(Mn＝2.06, SD＝0.40, range, 1.45-3.53) Among 25 Death Orientation items, respondents revealed the highest concern over the afterlife (Mn＝3.53, SD＝0.71), revealed the lowest anxiety about not knowing the next world after his or her death(Mn＝1.45, SD＝0.69), and relatively high concern over leaving careful instructions after death (Mn＝2.97, SD＝0.83) Respondents revealed low Death Orientation score(below 1.99) to 12 negative items(2, 3, 5, 6, 7, 9, 14, 17, 18, 19, 20, 22). Thus hospice volunteers seem to be preparing for their own death and shown positive Death Orientation to some items relatively. 3. According to personal attributes (demographic, socioecnomic, and relevant variables) of hospice volunteers, there were no significant statistic differences of Death Orientation score. Thus pre-existing Death Orientation of hospice volunteers and their motive of participation to the hospice service are to be considered important variables influencing the Death Orientation.

Objective: The purpose of this study is to investigate whether the athletic knee show greater rotation and translation movement than non-athletic knee during the treadmill walking with their preferred speed in a complete gait cycle. Method: Thirty young and healthy male subjects participated in the study, fifteen handball players (mean age: 19.6 ± 1.4 years old, mean weight: 85 ± 11.9 Kg, mean height: 179.8 ± 4.7) and fifteen non-athletes (mean age: 22.8 ± 1.2 years old, mean weight: 74.5 ± 8.6 Kg, mean height: 175 ± 5.9). Three-dimensional positional coordinate of lower limb during treadmill walking were analyzed. Results: There were significant differences (t (22.014)=1.585, p=0.127 in the range of internal and external rotation with mean value for handball player (M=14.4513, SD=2.3839) was higher than non-athletes (M=13.3327, SD=1.337). The magnitude of the difference in the means (mean difference=1.11867, 95% CI: -0.34489 to 2.5822) was significant. There were also significant differences (t (17.956)=1.654, p=0.116 in the max abduction and adduction with mean value for handball player (M=5.7160, SD=2.49281) was higher than non-athletes (M=4.5773, SD=0.94667). The magnitude of the difference in the means (mean difference=1.138, 95% CI: -0.30805 to 2.58539) was significant. At significance level 0.05. Conclusion: Finding of this study suggest that to understand the actual characteristic of knee motion studies have to be done in different walking and running trial at variable speed.
