THE EFFECTS OF SPATIAL ATTENTION AND EMOTIONS ON GLOBAL AND LOCAL PROCESSES

Present study is designed to investigate modulations in global-local processes by emotions and spatial cues. Aim was to investigate the effect of emotions on global-local bias and to examine if symbolic cues modulate these processes by simultaneously presenting the cue and emotional picture. Using the Navon (1977) figures, participants were presented with (in)congruent displays formed by the (in)congruency between the global and local features. Before presenting the displays, emotional (Experiment 1A: positive, Experiment 1B: negative) or neutral picture was presented simultaneously with global, local or neutral symbolic arrow cues, used as spatial cues to bias attention in global and local levels respectively. Participants were then asked to choose one stimulus out of three options. Chosen stimulus is expected to indicate the bias of participants. Reaction time and global-local preference measurements were analyzed. Reaction time was not modulated by any of the factors. The global/local bias measurements revealed a shift from local to global bias in the presence of negative emotion. The findings reveal information on global and local processes by adapting new methodological approach. Keywords Global and local processes, positive and negative emotions, global cue, local cue, global-local preference

Determination of the Simplified Daylight Glare Probability (DGPs) Criteria for Daylit Office Spaces in Thailand

The increasing trend of employing glazed façades to utilize daylight in the buildings has made it necessary to develop measures to avoid excessive sunlight penetration in such daylit spaces. In Thailand, only a few studies have focused on daylight glare, and therefore, applicable criteria are required to fulfill the local preference. This study aimed to determine daylight glare thresholds on the basis of the occupants’ responses. A post-occupancy evaluation with a simplified daylight glare probability (DGPs) model was performed in eight open-plan office spaces located in Bangkok, Thailand. The occupants participated in a survey including a subjective questionnaire; the results showed that the DGPs model performed effectively for glare prediction, with a preference for a lower level than that found in the current references. Statistical analysis helped mark the threshold values for each glare sensation level: imperceptible–perceptible = 0.22; perceptible–disturbing = 0.24; and disturbing–intolerable = 0.26. The findings of this study can be considered as initial evidence for improving the understanding of local occupants’ perspectives and illumination standards, which currently encourage daylight utilization without any specific glare control strategies.

Implementasi Atribut Local Preference di Protokol BGP Untuk Optimalisasi Jaringan Backbone

In terms of Nework, Network Quality determine by some factor and one of the factor is come from a Backbone Network, when traffic data exchange is occuring there are two type of path that pass by data package which we call as Downstream and Upstream Path. Every interface that build in network computer hardware usually are supported by full duplex sistem therefore in one interface it could be pass by Upstream and Downstream Data Package at the same time. When configuring both of the path, the parameter should be adjusted or else there would be an invalid routing configuration, this state would impact in network quality. iBGP Routing would help Network Administrator to set the path based on parameter adjustment in iBGP routing protocol. There are some parameter that can be use to set the network path and one of them is call local preferences, with adjust the value on the atribute of local preference the downstream and upstream path could be manage to fit the network utilities.Keywords: routing, iBGP, local preference, backbone
