This research investigates the effect of leisure activities on lifestyle satisfaction of senior citizens. The target of this research is 202 people over 60 years of age who live in Seoul. Collected data was analyzed using frequency, percentage, average, T-test, one-way ANONA, and logistic regression analysis. SPSS and the Excel PC Program were used for the analysis. The following is the summary of the result of this research. First - in terms of participation in leisure activities: more active participation is observed with the elderly who have a spouse than with those who do not in every kind of leisure activity (except for the pastime activities). Second - all of the variables indicating the level of satisfaction from activities of the seniors who have a spouse are by far higher than those of the elderly who have no spouse. Third - the leisure activities and the satisfaction from the activities prove affective variables on whether they have a spouse or not. Notably, the religious leisure activities are enjoyed more by those senior citizens who are married. Comparatively, the unmarried senior citizens participate more actively in recreational and pastime leisure activities. This study suggests various practical means to promote leisure activities to the elderly and to raise the level of satisfaction received from those activities, as well as to help those who are concerned with understanding and improving lifestyle satisfaction of the elderly population. Nonetheless, this analysis is limited due to the restriction on the number of objects and samples studied. Therefore, studies to analyze leisure activities by regions in order to account for a more balanced set of systematical tools should follow.

PURPOSE: This study compared the effects of computer-based and virtual reality-based cognitive rehabilitation programs on the cognitive function, upper limb function, activities of daily living, and their impact on the prefrontal cortex in convalescent stroke patients. METHODS: Ten recovering stroke patients were assessed for their cognitive function, upper limb function, and daily living activities using the Neurobehavioral Cognitive Status Examination, the Korean version of the Fugl-Meyer Assessment, and the Korean version of the Modified Barthel Index. The prefrontal cortex activity was measured with functional Near Infrared Spectroscopy. The virtual reality-based cognitive rehabilitation group utilized a program of daily living activities delivered via a laptop and Oculus Rift. The computer-based cognitive rehabilitation group performed various cognitive tasks on an all-in-one PC. Both groups underwent cognitive rehabilitation training for 30 minutes per day, three times a week, for six weeks, with identical conventional rehabilitation therapies in the hospital. RESULTS: Both programs positively impacted the cognitive and physical functions. On the other hand, the virtual reality-based cognitive rehabilitation program had a larger influence on improving the cognitive and physical functions of convalescing stroke patients. CONCLUSION: The virtual reality program suggests its potential to enhance cognitive and physical functions in convalescent stroke patients through increased engagement, focus, real-time feedback, and game elements, making it a promising rehabilitation approach.

Modern steam turbine generators are being built as a higher power and larger system, experiencing more frequent starts and stops of operation due to a constant change of power demands. Hence, they are inevitably more vulnerable to various vibrations, and more often exposed to the danger of sudden vibration accidents than ever before. Even under the circumstances, in order to secure the system reliability of steampower plants and there by to supply safely the public electricity, it is important to prevent a sudden vibration accident in one hand and even when it happens, to raise an operating efficiency of the plants throught swift and precise treatments in the other. In this study, an interactive vibration diagnostic system has been developed to make the on-site vibration diagnosis of steam turbine generators possible and convenient, utilizing a note-book PC. For this purpose, at first the principal vibration phenomena, such as various unbalance and unstable vibrations as well as rubbing, misalignment, and shaft crack vibrations, have been systematically classified as grouped parameters of vibration frequencies, amplitudes, phases, rotating speeds at the time of accident, and operating conditions or condition changes. A new complex vibration diagnostic table has been constructed from the causal relations between the characteristic parameters and the principal vibration phenomena. Then, the diagnostic system has been developed to screen and issue the corresponding vibration phenomena by assigning to each user-selected combination of characteristic parameters a unique characteristic vector and comparing this vector with a diagnostic vector of each vibration phenomenon based on the constructed diagnostic table. Moreover, the diagnostic system has a logic whose diagnosis may be performed successfully by inputing only some of the corresponding characteristic parameters without having to input all the parameters. The developed diagnostic system has been applied to perform the diagnosis of several real cases of steam turbine vibration accidents. And the results have been quite satisfactory.

The docking and in silico ligand screening procedures can select small sets of lead -like candidates from large libraries of either commercially or synthetically available compounds; however, the vast number of such molecules make the potential size of this task enormous. To accelerate the discovery of drugs to inhibit several targets, we have exploited massively distributed computing to screen compound libraries virtually. The Korea@HOME project was launched in Feb. 2002, and one year later, more than 1200 PC's have been recruited. This has created a 31 -gigaflop machine that has already provided more than 1400 hours of CPU time. It has all owed databases of millions of compounds to be screened against protein targets in a matter of days. Now, the virtual screening software suitable for distributed environments is developed by BMD. It has been evaluated in terms of the accuracy of the scoring function and the search algorithm for the correct binding mode.

Purpose: The purpose of this study was to discern the effects of music therapy on the patients' level of anxiety and operative satisfaction during cataract surgery under local anesthesia. Method: The subjects for this study were fifty patients. Half of the subjects were categorized as an experimental group and the other half as a control group. All of the subjects were admitted to one hospital in Seoul for cataract surgery. This study was conducted from September 7 to October 2, 2002. The level of anxiety determined by self-reporting anxiety, pulse rate, systolic blood pressure, and diastolic blood pressure, was measured before and after the music therapy. The satisfaction degree was measured after the surgery. The tools for this study were Spilberger's state anxiety inventory and Patient Care Management System. Each patient in the experimental group chose the music used in his/her surgery and it was played through an audio system in the operating room. The data analysis was performed using the SAS/pc+(version 8.0). Results: 1. The anxiety of the experimental group decreased significantly compared to the control group. 2. The pulse rate of the experimental group decreased more than the control group. 3. The blood pressure of the experimental group decreased more than the control group. 4. The operative satisfaction of the experimental group was higher than the control group. Conclusion: According to the previous results, music therapy turned out to be a very efficient way to increase the satisfaction of a cataract patient after surgery by reducing the anxiety and the pulse rate of the patient during an operation with local anesthesia.

Clubroot disease caused by Plasmodiophora brassicae is one of the most serious diseases in Brassica crops worldwide. In this study, the pathotypes of 12 Korean P. brassicae field isolates were determined using various Chinese cabbage including 22 commercial cultivars from Korea, China, and Japan, and 15 inbred lines. All P. brassicae isolates exhibited the typical clubroot disease on non-clubroot resistant cultivar, indicating that the isolates were highly pathogenic. According to the reactions on the Williams' hosts, the 12 field isolates were initially classified into five races. However, when these isolates were inoculated onto clubroot-resistant (CR) cultivars of Chinese cabbage, several isolates led to different disease responses even though the isolates have been assigned to the same race by the Williams' host responses. Based on the pathogenicity results, the 12 field isolates were reclassified into four different groups: pathotype 1 (GN1, GN2, GS, JS, and HS), 2 (DJ and KS), 3 (HN1, PC, and YC), and 4 (HN2 and SS). In addition, the CR cultivars from Korea, China, and Japan exhibited distinguishable disease responses to the P. brassicae isolates, suggesting that the 22 cultivars used in this study, including the non-CR cultivars, are classified into four different host groups based on their disease resistance. Combining these findings, the four differential hosts of Chinese cabbage and four pathotype groups of P. brassicae might provide an efficient screening system for resistant cultivars and a new foundation of breeding strategies for CR Chinese cabbage.
