Recently studies have shown that conditional branches can be accurately predicted by recording the path leading up to the branch. But path predictors are more complex and uncompatible with existing pattern branch predictors. In order to solve these problems, we propose a simple path branch predictor(SPBP) that hashes together two most recent branch instruction addresses. In addition, we propose a pattern/path hybrid branch predictor composed of the SPBP and existing pattern branch predictors. Through the trace-driven simulation of six benchmark programs, the performance improvement by the proposed pattern/path hybrid branch prediction is analysed and validated. The proposed predictor can improve the prediction accuracy from 94.21% to 95.03%.

Effective management of knowledge is essential to keep up with demands of this challenging information age. The first step for this kind of management would be to define indicators to evaluate the quality of knowledge. In this paper, we use five latent variables (intrinsic quality, representational quality, ease of use of quality, maintainable quality, usage of quality) as basis for a preliminary path analysis for knowledge management. Preliminary study results showed that high intrinsic quality does not necessarily guarantee high frequency of use. A modified questionnaire is made and is used for SERVQUAL. The result of SERVQUAL shows that customers are not relatively happy about both intrinsic quality and its ease of use. Additional path analyses are done for both expected and observed quality indicators. The path model based on the expectation indicated that the presentation method of knowledge would induce its easy maintenance while that based on observation did not back up the same phenomenon.

We estimated phenotypic selection on the height and number of flowering-stalks in a rosette annual Cardamine hirsuta by applying path analysis to the data collected at three natural populations located in central Japan. The path from rosette size was positively connected with the fruit production through the both height and number of flowering-stalks. In the all three populations, the paths from the number of stalks were more strongly connected with the fruit production than from the height of stalks. The paths from the rosette size showed similar magnitude with the number of stalks and the height of stalks. The direct path from rosette size to the fruit production was detected only at one site. These results suggest stronger phenotypic selection on the rosette size through the number of stalks than the height of stalks. The lateral branching rather than increment of individual inflorescence size is the major response to control the fruit production for C. hirsuta growing in a natural habitat.

Asphalt concrete pavements are often destroyed within the intended design life due to the increasement in traffic volume. The most common types of asphalt concrete pavement damages are permanent deformation and fatigue cracking, and so on. In this research, characteristics of traffic loadings and lateral wheel path distributions are analyzed using the field survey on traffic flow. The obtained traffic characteristics can be used to the decision making for the maintenance policy of roads. According to the traffic lane analysis for the 2nd and 3rd lanes, inner lane vehicles tended to pass to the right side to avoid the opposite side vehicles. In addition, the outside lane vehicles were deviated to the left side to avoid passengers. It is also noted that the lateral wheel path distributions was close to the normal distribution.

This study attempted to test the path model that can predict Korean adult suicidal ideation. The subjects were 459 adults aged between 19 and 64 who agreed to this study among quota sampled by the population, sex, and region of the metropolitan city. The path model of collected data was estimated using SPSS 24.0 program and AMOS 22.0. The results of the bias-corrected percentile method for verifying the significance of the mediator effect of the final model showed that suicidal attitude, depression, and stress were found to be mediating effects of health status on suicidal ideation. Suicide attitude and stress were found to mediate the effects of health status on depression. And the effect of drinking on depression was mediated by stress. This result is expected to be used as a practical basis for the development of suicide prevention and intervention programs for adults in the future.

The objective of this study was to compare the condylar path and the anterior angle of articular fossa and to analyze the pattern of condylar path in edentulus patients. Nineteen male and female edentulous patients with normal masticatory system ranging in age 42 to 78, without present symptoms and any history of TMJ disturbance were selected for this study. On the computer analysis on the transcranial radiographs of the TMJ, the angle of slope of articular eminance and condylar path to the Frankfort Horizontal Plane and the height of glenoid fossa was measured respectively, and stuied their interrelationship comparatively. Obtained results were asfollows. 1. The angle of the slope of articular eminence averaged 37.28 degree. and there was no significant difference between the right and left side. 2. The condylar path angle averaged 29.05 degree and there was no significant difference between the right and left side. 3. The height of the glenoid fossa averaged 8.11 mm and there was no significant difference between the right and left side. 4. The sequence of the frequence of condylar movement patterns were concavex curve(39.5% ), 'S' shape curve(34.2%), reverse 'S' shape(15.8%) and convex curve(10.5%). 5. The horizontal distance of the point of the changed curve of the condylar path averaged 2.91 mm. 6. The height of glenoid fossa was highly correlated to the slope of articular eminence and relatively highly correlated to tile condylar path and the condylar path was closely correlated to the slop of articular eminence.

Space is integrated or segment with organic formation by circulation path. It estimates important problem to grasp as factor that promote movement of visitor and space organization without grasping circulation as connection relation about simple space function from these viewpoint, is a thing which this study does not cause confusion to visitor's circulation path through data that analyze form of space connection and visitor's circulation path as quantitative in museum space and layout form that access by easy each unit exhibition grasps what it is. This study does factor grasping for guideline and inspection circulation path of layout by purpose in exhibition space on the basis of analytical result that grasps connection form between exhibition area that grasp laying stress on visitor's movement and appears in space through follow-up survey for circulation path of museum exhibition area. Space connection form that is expose by sequence of investigation and analysis(II) estimates on constituent affecting to visitor's circulation, and these do not speak for all space connection forms at the museum, but may systematize typology about connection form of unit spaces to utilize by indicator pointer of space planning if continue study to various spatial sphere more than hereafter. Unit exhibition area, divide connection form of space by grid and tree and laying stress on this quantitative data by spectator follow-up survey comparison and Estimate that space connection form provides partial basis of judgement for supposition that can promote direction and circulation path about visitor's movement if summarize result of investigation and analysis (III).

This study was conducted to grasp users' preferences and behavior of forest paths and to provide basic data for forest path construction in the future. Among forest path users, males and females over 20 years old were surveyed on forest path preferences, motives for visiting, using time and distance, companions, and sources for obtaining information on forest paths. A total of 587 people participated in the questionnaire, and cross-analysis was conducted simultaneously using the SPSS statistical program. In analyzing the preference of forest paths, it was found that male and the general public preferred trekking path for activities while female and foresters preferred forest path for relaxation and healing (p<0.05). As for the motives for visiting forest paths, the response that they visited for a walk/rest was the highest in gender, occupation, and age group. As for the number of annual visits, less than 5 was the highest in overall, and foresters tended to visit forest path more often than the general public, and the number of visits to the forest paths increased with age (p<0.01). The most common route to acquire information about forest paths is the Internet, while the Internet use is relatively low in those over 60s (p<0.05). The response ratio of accompanying their family in visiting forest paths were the highest, while the response in their 20s and 60s was the most in accompanying their friends (p<0.05).
