The present work was designed to compare the larvicidal efficacy of four indigenous fish namely Rasbora daniconius, Esomus dandricus, Trichogaster fasciata and Trichogaster lalia with an exotic top water minnow, Gambusia affinis in the laboratory for 30 days. The experiment was performed in glass aquarium with 100 larvae as a feed to each one for duration of 2:00 hours. The study revealed that all the fishes are concerned with larvicidal potential with differences in their feeding efficiency. Mean final body weight was found to be maximum in exotic mosquito fish, Gambusia affinis (2.52 ± 0.414) in the present study and it was significantly different (p = 0.0001) from other fishes. The sequence of predation efficacy noted in the present study was Gambusia affinis > Esomus dandricus > Rasbora daniconius > Trichogaster fasciata > Trichogaster lalia.

Typically, growth can be defined as the change in size (length, weight) over time. The length-weight relationship (LWR) and annual condition factor of an economically important snow trout, Schizothorax niger, from Dal lake of Kashmir was studied and reported in this communication. A total of 120 specimens were collected with the help of traditional fishing gear during 2012-2013. The coefficient ‘b’ value of the LWR suggested allometric growth throughout the year except in April, July and September where the growth was isometric (b=3). A trend line graph was applied to compare condition of fish in different months as per the relationship, which indicated declining growth condition. The condition factor showed an overt variation with highest value during the breeding season. The result obtained in this study will be useful for fishery managers to impose adequate regulations for fishery and sustainable management.

There have been increasing attempts to control memory, attention and naming difficulties of the elderly by using game applications on a tablet device. It is necessary to take into account several factors for such attempts to be realized effectively. This study applied the group rehabilitation therapy programs of a wireless interactive cognitive rehabilitation system and of paper-pencil methods to patients with dementia and the elderly with mild cognitive impairment, respectively, and sought to present the factors to be considered in order to achieve both efficiency and efficacy of cognitive rehabilitation therapies. The mild cognitive impairment group had few difficulties in participating in games connected with multi-users, understanding training directions and adjusting a training level of difficulty and speed, whereas the mild AD group, whose cognition fell below -2SD in normative data, had difficulties while a group rehabilitation program was being carried out with only one therapist and a device, and were continually directed one to one on how to use the device. In the therapy program of a paper and pencil method, while the mild cognitive impairment group understood clearly every task, the dementia group could complete the task only under assistant's repeated directions and explanation. The reason why engineering techniques have been applied in cognitive rehabilitation training programs for the elderly with dementia is the advantages of such programs like immediate feedback depending on user's performance and a decreased burden of labor force. It is cognitive functions of the device user that serve as a highly significant variable to predict efficiency and effectiveness of such engineering techniques.

After stroke, these changes consequently result in the limitation of upper limb joint range of motion or muscle shortening, and spasticity, causing the reduction of hand functions. This study aimed to investigate the effect according to the types of resting hand splints, particularly the effect of the application of resting hand splint. This study was performed in two groups, which were determined by random assignment according to the order of visits of 52 subjects who were diagnosed of stroke. The patients were divided into a dorsal resting hand splint group (n = 26) and volar resting hand splint group (n = 26). The data collected in this study was analyzed using SPSS version 18.0. For the difference in Modified Ashworth Scales (MAS), surface ElectroMyoGraphy (sEMG), and Wrist Active Range of Motion(AROM) before and after the intervention in two groups, paired t-test was performed, and independent sample t-test was performed to compare the change(s) before and after the intervention in two groups. Statistical significance level was α = .05. First, there was a significant difference in wrist MAS, AROM, and sEMG in the group of dorsal resting hand splint. Second, there was no significant difference in wrist MAS and AROM in the group of volar resting hand splint, but there was a significant difference in wrist sEMG. Third, there was a significant difference in wrist MAS and AROM in the group of resting dorsal hand splint as a result of comparing change(s) between two groups, but there was no significant difference in wrist sEMG. Through this study, it was found that dorsal resting hand splint was more effective in the reduction of wrist spasticity and improving AROM than volar resting hand splint in stroke patients. Applying resting hand splint to stroke patients would not only have preventive effects but also have great influence on the improvement of hand function.

Background/Objectives: The Identifier (ID) and Locator(Loc) split is a key concept in the current Internet environment and the future Internet environment. The binding of ID to Loc is necessary to route/forward packets, which is called as ID/Loc mapping system. Methods/Statistical analysis: We propose a novel ID/Locator Mapping System (ILMS) mechanism using the bloom filters (BFs) to store information about the identifier. The proposed bloom filters stores the information about the identifiers belonging to the domain managed by the ILMS. Findings: The critical challenge in building the mapping system is scalability simply because the vast number of ID exists in the network and there is no mechanism that can be aggregated as an IP address, since IDs are assumed to be flat. The proposed mapping system is a network of ILMS server in a forest by multiple trees with peering relationship. The main idea is to construct the hierarchical ILMS to manage only a limited number of IDs and so can extract a bit that can be tested for given ID in each ILMS. Improvements/Applications: Scalability issue was addressed by compressing the BFs to indicate the IDs of the child ILMS server.
