In this paper, a new GA-based methodology with information granules is suggested for construction of the fuzzy classifier. We deal with the selection of the fuzzy region as well as two major classification problems-the feature selection and the pattern classification. The proposed method consists of three steps: the selection of the fuzzy region, the construction of the fuzzy sets, and the tuning of the fuzzy rules. The genetic algorithms (GAs) are applied to the development of the information granules so as to decide the satisfactory fuzzy regions. Finally, the GAs are also applied to the tuning procedure of the fuzzy rules in terms of the management of the misclassified data (e.g., data with the strange pattern or on the boundaries of the classes). To show the effectiveness of the proposed method, an example-the classification of the Iris data, is provided.

This study is based on the use and performance of bamboo reinforcements in construction of low-cost structures. This study investigated the physical and mechanical properties of bamboo reinforcements. Bamboo reinforced concrete beam specimens were tested with different reinforcement ratios and observed the load capacity, deflection and failure patterns. It was observed that, flexural strength of bamboo reinforced column is sufficient higher than plain cement concrete and comparable to steel reinforced concrete beams. Bamboo reinforced concrete columns with different reinforcement ratio also tested and observed the ultimate compressive strength and failure pattern. It found, all columns failed in a similar pattern due to crushing of concrete. According to cost analysis, bamboo reinforced beams and columns with moderate reinforcement ratio showed the best strength-cost ratio among plain cement concrete and steel reinforced concrete.

The primary aim of this paper is to analyze the resultative adjunct clause, i.e., (thus/thereby/hence) ~ing participle and provide explicit syntactic, semantic and sociolinguistic explanation on the question what causes the cause-focused causal construction with resultative (thus/thereby/hence) ~ing participle in English. What comes first is either cause or effect clause. This study explores the recent style shift of causal constructions from the effect-focused pattern to the cause-focused pattern. In this study, we argue that the increasing number of the cause-focused main clause with a resultative ~ing participle clause shows the process of the style evolution improving speech/wring style in many respects including syntactic simplification, clarification of the sentence meaning with impact on the focused clauses, and improvement of the flow of speech/writing. The style shift found in the English resultative adjunct clauses, i.e., (thus/hence/thereby) ~ing participle constructions prove to be the style evolution from syntactic, semantic and sociolinguistic point of views.

This study aims to extract key topics through text mining of incident records (incident history, post-incident measures, preventive measures) from construction safety accident case data available on the public data portal. It also seeks to provide fundamental insights contributing to the establishment of manuals for disaster prevention by identifying correlations between these topics. After pre-processing the input data, we used the LDA-based topic modeling technique to derive the main topics. Consequently, we obtained five topics related to incident history, and four topics each related to post-incident measures and preventive measures. Although no dominant patterns emerged from the topic pattern analysis, the study holds significance as it provides quantitative information on the follow-up actions related to the incident history, thereby suggesting practical implications for the establishment of a preventive decision-making system through the linkage between accident history and subsequent measures for reccurrence prevention.

The importantce of a development of competitiveness in domestic construction industry is growing as some of domestic construction markets is scheduled to open to foreign competing firms with higher level of construction technology and management. A national level of competitiveness in domestic construction industry and firms are partially, but significantly, affected by a technology level and a characteristics of production pattern. The purpose of the study is mainly to analyze and identify a technology level, production pattern and a development stage of R&D activities of domestic construction industry and firms. Based on these findings the study draws on a concluding remarks and derives technology policy implications. Results of analysis in the study impliy that (1) competitiveness of domestic construction firms(industry) in terms of technology level is relatively weak as compare to that of advanced foreign competing firms, (2) degrees of substitution of capital for labor are seemed to be relatively high, (3) R&D (investment) activities of domestic construction firms are generally spread out in forms of import, adjustment and betterment, and (4) only a small number of big domestic construction firms are seemed to afford to R&D investment for research facilities and equipments, but not enough for higher level of R&D man-power. The study suggests that technology policy for construction industry should be based on a fundamental policy directions. For example the increase in size and heightened quality level of R&D man-power should be placed in a top priority in policy agenda. Sound and specific policy items should be developed for planning and design, and maintenace and inspection technology in order to lead domestic industry to compete with foreign firms with full strength.

Objectives : The aim of this paper is to study the methodology for effectively analyzing the "Jinguiyaolue" prescriptions using database, and to explore possibilities of applying the data construction and query produced in the process to comparative research with other texts in the future. Methods : Using "Xinbianzhongjingquanshu(新編仲景全書)" as original script, the contents of "Jinguiyaolue" were entered into the database, in which one verse would be separated according to content for individual usage. Also, data with medicinal construction and disease pattern information of the previously constructed "Shanghanlun" database designed for comparison with other texts was applied for comparative analysis. Results : For input and analysis, 6 tables and 12 queries were made and used. Formulas were accessible by using herbal combinations, and applications of these formulas could be assembled for comparison. Formulas were also accessible by using disease pattern combinations, and combinations of herbs and disease pattern together were also applicable. In comparison with other texts, examples and frequency of usage of herbs could be relatively accurately compared, while disease patterns could not easily be compared. Conclusions : Herbal combinations, disease pattern combinations could yield related texts and herb/disease pattern combinations of the prescriptions in the "Jinguiyaolue", which shortened time needed for research among formulas in texts. However, standardization research for disease pattern is necessary for a more accurate comparative study that includes disease pattern information.

We selected 81 universities (39.1%) for research and close analysis to analyze the current availability of courses in the field of clothing construction at four-year domestic universities. The results of the analysis shows that curriculum is currently composed of theoretical and practical courses that continue to be developed in diverse areas of study. Despite having classes with underlying similarities and differences, research shows that the course curriculum is constructed systematically with both theory and practice at each stage. Distribution of curriculum in the field of clothing construction were organized and analyzed by similar courses in 4 larger groupings and 9 sub-groups. Analysis of the large groupings showed that sewing courses (19.8%), pattern development courses (41.0%), advanced sewing courses (14.1%), and miscellaneous courses (26.1%) were established. Analysis of the sub-groups showed that basic theory and sewing courses (3.6%), sewing courses (16.1%), flat pattern courses (17.9%), draping pattern courses (14.6%), pattern CAD courses (7.3%), tailoring and advanced sewing courses (8.5%), scientific sewing and apparel production processing courses (1.4%), special sewing courses (3.9%), and miscellaneous and new subject courses (26.1%) were established. Overall analysis of the organization distribution was conducted in the order of pattern development (39.9%), miscellaneous & new subject (26.1%), basic theory and sewing (19.8%), and advanced sewing (14.0%). Field analysis from various angles indicates that pattern development, new subject courses, and miscellaneous courses had a relatively higher proportion than other major courses. From this it can be inferred that this trend is an effort to develop individuals to adapt to a rapidly changing fashion industry and environment. The composition of courses also shows great advancement towards diversification and course development. However, there is still insufficient exchange between industrial and education sites. As active exchange continue to be demanded, classification standards for new subject courses and titles of such studies have become unclear and have reached limitations.

Unlike other craft workers, construction craft workers perform their work under diverse working conditions, which means that their working pattern and postures continuously change. While construction craft workers are vulnerable to musculoskeletal disorders, due to the unique factors of their working conditions, their actual condition has not yet been accurately investigated. For this reason, this research aims to develop a method of measuring the musculoskeletal load of construction workers by reviewing various motion measuring methods to which state-of-the-art sensors are applied. This research is expected to serve as the basis for developing a system to measure the musculoskeletal load of construction workers.

On construction sites, it is important to monitor the performance of construction equipment and workers to achieve successful construction project management; especially, vision-based detection methods have advantages for the real-time site data collection for safety and productivity analyses. Although many researchers developed vision-based detection methods with acceptable performance, there are still limitations to be addressed: 1) sensitiveness to the shape and appearance changes of moving objects in difference working postures, and 2) high computation time. To deal with the limitations, this paper proposes a detection algorithm of construction equipment based on Integral Channel Features. For validation, 16,850 frames of video streams were recorded and analyzed. The results showed that the proposed method worked in high performance in terms of accuracy and processing time. In conclusion, the developed method can help to understand useful site information including working pattern, working time and input manpower analyses.
