Background: To illustrate multiple approaches and to assess participation rates adopted for a community based smoking cessation intervention programme in rural Kerala. Materials and Methods: Resident males in the age group 18-60 years who were 'current daily smokers' from 4 randomly allocated community development blocks of rural Thiruvananthapuram district, Kerala (2 intervention and 2 control groups) were selected. Smoking status was assessed through house-to-house survey using trained volunteers. Multiple approaches included awareness on tobacco hazards during baseline survey and distribution of multicolour anti-tobacco leaflets for intervention and control groups. Further, the intervention group received a tobacco cessation booklet and four sessions of counselling which included a one-time group counselling cum medical camp, followed by proactive counselling through face-to-face (FTF) interview and mobile phone. In the second and fourth session, motivational counselling was conducted. Results: Among 928 smokers identified, smokers in intervention and control groups numbered 474 (mean age: 44.6 years, SD: 9.66 years) and 454 respectively (44.5 years, SD: 10.30 years). Among the 474 subjects, 75 (16%) had attended the group counselling cum medical camp after completion of baseline survey in the intervention group, Among the remaining subjects (n=399), 88% were contacted through FTF and mobile phone (8.5%). In the second session (4-6 weeks time period), the response rate for individual counselling was 94% (78% through FTF and 16% through mobile phone). At 3 months, 70.4% were contacted by their mobile phone and further, 19.6% through FTF (total 90%) while at 6 months (fourth session), the response rate was 74% and 16.4% for FTF and mobile phone respectively, covering 90.4% of the total subjects. Overall, in the intervention group, 97.4% of subjects were being contacted at least once and individual counselling given. Conclusion: Proactive community centred intervention programmes using multiple approaches were found to be successful to increase the participation rate for intervention.

A Vehicle Tracking System consists of GPS tracking device which fits into the vehicle and captures the GPS location information at regular intervals to a central GIS server, and GIS tracking server providing three major responsibilities: receiving data from the GPS tracking unit, securely storing it, and serving this information on demand of the user. GPS based tracking systems supporting a multi-session processing among RMA, RM, and RCP can make a quick response to various services including other vehicle information between RSU and OBU on demand of the user. In this paper we design RSU lower layers and RCP applications in OBU for a multisession processing simulation and test message processing transactions among RMA-RM and RM-RCP. Furthermore, we implement the additional functions of handling access commands simultaneously on multiple service resources which are appropriate for the experimental testing conditions. In order to make a multi-session processing test, it reads 30 resource data,0002/0001 ~ 0002/0030, in total and then occurs 30 session data transmissions simultaneously. We insert a sequence number field into a special header of dummy data as a corresponding response to check that the messages are received correctly. Thus, we find that GIS service system with a multi-session processing is able to provide additional 30 services in a same speed of screen presentation loading while identifying the number of session processing of Web GIS service, the number of OBU service, and the speed of screen presentation loading by comparing a single session and a multi-session of GIS service system.

The present study was conducted to investigate the attributes of ram sexual behaviour under different social conditions. Six intact rams and eight overiectomized ewes were used in this experiment. Ewes were artificially brought into oestrus. All mating traits were recorded every 10 sec during a 1 h mating session under five social conditions viz., ram exposed to single oestrus ewe, ram exposed to single oestrus ewe and audience ram, ram exposed to multiple oestrus ewes, ram exposed to single oestrus ewe with competitor ram and ram exposed to multiple oestrus ewes with competitor ram. Mean intensity of the mating activities during the 1 h mating session under five social conditions was compared. Either vocalization or leg kicking was found to be the predominant teasing activity under all five conditions. Sniffing differed significantly (p<0.05) between different social conditions. Vocalization, leg kicking, and leg kicking with vocalization did not differ significantly (p<0.05) between different social conditions. Mounts/h in the multiple oestrus ewe condition was higher and differed significantly (p<0.05) from other social conditions. Ejaculations/h for the experimental ram was higher when exposed to multiple oestrus ewes in comparison to other social conditions. Mounts/ejaculation was low in the audience ram condition in comparison to the other four social conditions.

In this paper, we propose an application layer-based vertical handover management protocol, called multihoming RTP (mhRTP), for real-time applications with seamless mobility across heterogeneous wireless access networks. The proposed multi-homing RTP provides a soft handover by utilizing multiple available wireless access network interfaces simultaneously. The newly available path is dynamically added to the ongoing session by the mhRTP session manager. Also the decision making of QoS-improving or QoS-guaranteed handover is possible based on the estimation of available bandwidth in each candidate network. The performances of the proposed mhRTP have been analyzed through a series of simulations on OPNET network simulator. From the performance analysis, we confirmed that the proposed mhRTP can provide QoS-guaranteed vertical handover with efficient session managements.

In the present study, we apply the multiple cue probability learning (MCPL) paradigm to examine consumer learning from feedback in repeated trials. This paradigm is useful in investigating consumer learning, especially learning the relationships between the overall quality and attributes. With this paradigm, we can analyze what people learn from repeated trials by using the lens model, i.e., whether it is knowledge or consistency. In addition to introducing this paradigm, we aim to demonstrate that knowledge people gain from repeated trials with feedback is robust enough to weaken one of the most often examined contextual effects, the asymmetric dominance effect. The experiment consists of learning session and a choice task and stimuli are sport rafting boats with motor engines. During the learning session, the participants are shown an option with three attributes and are asked to evaluate its overall quality and type in a number between 0 and 100. Then an expert's evaluation, a number between 0 and 100, is provided as feedback. This trial is repeated fifteen times with different sets of attributes, which comprises one learning session. Depending on the conditions, the participants do one (low) or three (high) learning sessions or do not go through any learning session (no learning). After learning session, the participants then are provided with either a core or an extended choice set to make a choice to examine if learning from feedback would weaken the asymmetric dominance effect. The experiment uses a between-subjects experimental design (2 × 3; core set vs. extended set; no vs. low vs. high learning). The results show that the participants evaluate the overall qualities more accurately with learning. They learn the true trade-off rule between attributes (increase in knowledge) and become more consistent in their evaluations. Regarding the choice task, there is a significant decrease in the percentage of choosing the target option in the extended sets with learning, which clearly demonstrates that learning decreases the magnitude of the asymmetric dominance effect. However, these results are significant only when no learning condition is compared either to low or high learning condition. There is no significant result between low and high learning conditions, which may be due to fatigue or reflect the characteristics of learning curve. The present study introduces the MCPL paradigm in examining consumer learning and demonstrates that learning from feedback increases both knowledge and consistency and weakens the asymmetric dominance effect. The latter result may suggest that the previous demonstrations of the asymmetric dominance effect are somewhat exaggerated. In a single choice setting, people do not have enough information or experience about the stimuli, which may lead them to depend mostly on the contextual structure among options. In the future, more realistic stimuli and real experts' judgments can be used to increase the external validity of study results. In addition, consumers often learn through repeated choices in real consumer settings. Therefore, what consumers learn from feedback in repeated choices would be an interesting topic to investigate.

This research paper explores selected behavioral outcomes of a multi-sensory environment. An experimental study was conducted at a specialized facility for the ageing in Sweden. The objective was to explore the effects of agitated behaviors of ageing residents with dementia and to identify any short-term effects. Appointed nursing staff was instructed to record physically and verbally agitated behaviors on three occasions; pre-session, mid-session, and post-session. Over seven months, nine participants received sixty-one sessions in the multi-sensory room. ANOVA and Post hoc multiple comparisons were performed to identify the differences in mean between each session. Generally irritated/frustrated behavior and eating/drinking non foods revealed statistically significant differences, while there were no significant results in verbally agitated behavior. One short-term effect was observed in one agitated category; a reduction of generally irritated/frustrated behavior. These results suggest that the multi-sensory environment can have positive effects on some manifestations of agitated behavior. This study proposes that a multi-sensory environment may be recommended as an alternative intervention for physically agitated behavior among this category of residents. However, more research is needed to understand the specific effects and the best use of the multi-sensory environment for this population.

Objectives : This study was to investigate the regulatory effect of electro-acupuncture on Jogsamni ($ST_{36}$) in bradygastric condition or gastroparesis which is a neuropathic complication of type 2 diabetes mellitus(T2DM), assessed using 4-channel electrogastrography (EGG). Methods : It was a case series study. Each patient was given electro-acupuncture(EA) one point, Jogsamni($ST_{36}$) or Gyeonu($LI_{15}$) bilaterally for thirty minutes with 2Hz bipolar square wave frequency and moderate intensity of stimulation. With attaching electrodes around stomach region throughout pre-acupuncture, acupuncture, and post-acupuncture session, these parameters were produced; percent rate of bradygastria power compared to sum of power in all kind of gastric rhythm(% bradygastria), dominant frequency(DF) and dominant power(DP). Parameter was analysed per each channel's variable change from pre-acupuncture session by paired t-test. Results : There was statistically significant decrease in % bradygastria parameters on one of the $ST_{36}$ treated patients from pre-acupuncture session and to post-acupuncture session(P=0.015, P=0.008 respectively). A marginal significant decrease of DP was shown in the other $ST_{36}$ treated patient from pre-acupuncture session through post-acupuncture session(P=0.049). Combined data of two $ST_{36}$ Treated patients showed that there was significant decrease of %bradygastria from pre-acupuncture session to acupuncture session(P=0.020), and was decrease of DP from pre-acupuncture session to post- acupuncture session(P=0.020). Conclusions : EA at $ST_{36}$ resulted in statistically significant decrease in %bradygastria and DP for dysrhythmic condition in T2DM gastroparesis patients. Considering this limited results, further study will be needed to elucidate the effect of multiple-acupuncture on gastric myoelectrical activities.
