Macrobeilthic fauna were collected using a van Veen grab $(0.1m^2)$ to investigate the spatial characteristics of the macrobenthos community at 28 stations near the Nakdong River estuary, Southeast Korea, in September 2001. A total of 203 species were sampled with a mean density of $1,554 ind./m^2$ and a biomass of $252.3 gWWt/m^2$. Annelids were the dominant faunal group in terms of species and density, with 68 species and a mean density of $1,031ind./m^2$, which comprised 33.5% and 66.3% of the total benthic animals, respectively. Based on density, three Polychaetes were dominant Tharyx sp· $(420ind./m^2)$, Lumbrineris longifolia $(143ind./m^2)$, and Sternaspis scutata $(118ind./m^2)$, along with a bivalve Theora fragilis $(129 ind./m^2)$. On cluster analysis, the benthic community was classified into four groups based on the species composition: Group-1 occurred in disturbed areas, Group-II in coastal regions, Group-III in central mariculture grounds, and Group-IV offshore. Environmental factors (mean gain size, organic carbon, and depth) were primarily correlated with the macrobenthos community structure. A benthic pollution assessment based on the macrobenthos community structure showed that Group-I and Group-II were located in a coastal area that had been severely disturbed by construction of Busan new port and various pollutants, Group-III was gradually polluted, while offshore Group-IV was the most stable.

Community-based group exercise programs for people with chronic stroke are relatively uncommon in Korea. In addition, it is currently not known whether a community-based group exercise program is effective or not. The purpose of this study was to evaluate an 8 week community-based functional exercise program for its effects on balance performance and occupational performance in persons with chronic stroke. Twenty-five community-dwelling individuals with stroke participated in this program. Outcome of the program was assessed by the Berg Balance Scale and the Canadian Occupational Performance Measure (COPM). The functional exercise program lasted for eight weeks, with a 1-hour program twice per week and it consisted of mobility, stability, balance, functional strength, and gait training. The subjects were trained by one physical therapist but were under one-to-one supervision from students. The data of sixteen individuals who scored more than 24 on the Mini-Mental State Examination (MMSE) were analyzed. There was a significant effect both in terms of the COPM Performance Score & the Satisfaction Score (p=.002) and with the Berg Balance Score (p=.001). It was found that a short-term community-based exercise program could improve both performance of activities and balance. Further, all subjects reported that they were satisfied with this program.

Objective : The purpose of this study was to evaluate the influence of a community based group exercise intervention on motor functional capacity. To evaluate the immediate(post-treatment) effects after 6-weeks exercise program on the group exercise intervention(PNF and Circuit exercise). Methods : Subjects-Included persons with stroke who were living in the community. Thirty-seven subjects were randomly assigned to the PNF, Circuit exercise and control group participated in a repeated measures design that evaluated the subjects with pre-treatment, post-treatment(6 weeks). Functional ability outcome measures assessed the motor assessment scale(MAS) and EMG. Both treatment groups participated in exercise cJass three times a week for 6 weeks. Group programs focused on balance, functional motor capacity and walking ability. The PNF program was modified PNF pattem and techniques with emphasis on functional tasks when possible, as well as stretching of the more affected limb particularly in the more affected shoulder. The Circuit program with subjects completing practice at a selies of work station as well as participating in walking races and relay with other members of the group. Results : Compared with the control group, the treatment group had larger improvements in the motor function ability after 6 weeks treatment and Post-treatment test scores were more significant than the pre-treatment score. 1. Motor function were assessed by using MAS, sit to stand, walking and upper function were assessed pre-treatment versus post-treatment measures revealed a statically significant(p<.05). There were significant differences between the groups. Compared with the control group, the treatment group had larger improvements. 2. In the treatment groups, demonstrated difference in the electromyographic activation of biceps, triceps, quadriceps and tibialis anterior muscles on the paretic side in the response to the reaching arm movement and stepping motion in stance. The difference in muscle activation improvement were not statically significant. Conclusion : The results of this study showed that the PNF and Circuit group exercise intervention can improve motor functional ability. This study suggests that the PNF and Circuit exercise programs is appropriate for community-based group exercise principles. It leads to gain and maintain potential function for disabled persons after stroke in the community.

Purpose: This study was conducted to investigate the effects of a positive psychology improvement program on elders' depression and death anxiety. Methods: This was conducted as a quasi-experimental study with non-equivalent control group pretest-posttest design. The participants were community elders aged over 65 recruited by convenient sampling. A total of 94 elders (32 in the individual experimental group, 32 in the collective experimental group, and 30 in the control group) participated. Data were collected between April and September, 2012 and analyzed by using SPSS/WIN 21. Results: The individual and group approach experimental groups had significantly lower scores of depression than the control group after the treatment (F=7.50, p=.001). For death anxiety, however, only the individual experimental group had a significantly lower score compared to the control group (F=4.56, p=.013). Conclusion: These results indicate that the positive psychology improvement program was effective in decreasing depression and death anxiety in the elderly. Therefore, the program needs to be applied in a customized way fittingly to the characteristics of the elderly in community, and individually and/or collectively according to its purposes.
