For fast-built and safe precast concrete (PC) construction, the dry mechanical splicing method is a critical technique that enables a self-sustaining system (SSS) during construction with no temporary support and minimizes onsite jobs. However, due to limited experimental evidence, traditional wet splicing methods are still dominantly adopted in the domestic precast industry. For PC beam-column connections, the current design code requires achieving emulative connection performances and corresponding structural integrity to be comparable with typical reinforced concrete (RC) systems with monolithic connections. To this end, this study conducted the standard material tests on mechanical splices to check their satisfactory performance as the Type 2 mechanical splice specified in the ACI 318 code. Two PC beam-column connection specimens with dry mechanical splices and an RC control specimen as the special moment frame were subsequently fabricated and tested under lateral reversed cyclic loadings. Test results showed that the seismic performances of all the PC specimens were fully comparable to the RC specimen in terms of strength, stiffness, energy dissipation, drift capacity, and failure mode, and their hysteresis responses showed a mitigated pinching effect compared to the control RC specimen. The seismic performances of the PC and RC specimens were evaluated quantitatively based on the ACI 374 report, and it appeared that all the test specimens fully satisfied the seismic performance criteria as a code-compliant special moment frame system.

A study on the morbidity of syphilis among 729 workers in Po Hang and Ul San Industiral Complexes at the routine periodical examination was performed. In addition to the morbidity, factors related to the disease infection such as educational level, religion, preventive measures taken by the workers, history of urethritis, and so on were studied and analysed to check significant relation. The results were as follows: 1. VDRL and RPR tests were undertaken to determine the sensitivity and specificity of RPR test which was utilized for all the workers studied. It revealed 86.4% of sensitivity and 87.7% of specificity from RPR test, and 81.8% of sensitivity and 90.1% of specificity from the VDRL test compared with RPCF test. There were 87.4% of agreement rate between RPR and VDRL. Actually, RPR was more sensitive but less specific than VDRL, and found to be a satisfactory screening test for syphilis especially in the fields. 2. Among the workers in Po Hang Area 24.0% of them revealed reactive result, and in Ul San Area 5.2% revealed reactive result showing 4.6 times of risk among workers in Po Hang Area. 3. There were no statistically significant differences between RPR reactive rates and personal characteristics such as educational level, religion, history of urethritis experience, history of coitus with prostitute, and preventive measures of V.D. taken by workers if evaluated by area of Po Hang and Ul Srn separately. 4. V.D. could be encountered as an occupational disease in certain conditions of working places and the psychosocial problems of workers. And so, it is necessary that all the workers working in special estates such as in Po Hang Industrial Complex should be checked to be screened out by RPR test at periodical examinations and part of pre-employment examination also should include RPR test to be compared with. Regardless of the workmen's compensation, establishment of V.D. treatment clinic or system for such industrial workers is urgently needed. Health education regarding V.D. is another subject to be performed.
