PurposeThe reliability and validity of a Korean version of the Obsessive-Compulsive-Inventory-Revised (OCI-R) was examined in non-clinical student samples.Materials and MethodsThe Korean version of OCI-R was administered to a total of 228 Korean college students. The Maudsley Obsessive Compulsive Inventory (MOCI), Beck's Depression Inventory (BDI), and Beck's Anxiety Inventory (BAI) were administered to 228 students.ResultsThe total and each of subscale of the Korean OCI-R demonstrated excellent internal consistency, good test-retest reliability, moderate convergent validity and good divergent validity.ConclusionIt was concluded that the Korean version of the OCI-R has strong psychometric properties as the original version.

In this research, the precast segmental construction of composite hollow reinforced concrete (RC) columns was studied. The precast segmental construction of composite hollow RC column requires guidelines for the connections between the bent cap and column segment, connections between column segmental joints, and connections between column segment and footing. The connection methods for different precast composite hollow RC piers were experimentally studied for rational resistance against shear force and bending moments. Two types of precast composite hollow RC columns and cast-in-place column were studied in this paper. The performance of these columns was evaluated through experiments. The precast column erected with a base-plate connection exhibited a performance similar to the cast-in-place column.Bridge construction technology has made significant progress in developing new types of high-performance, construction materials. However, most of the current technology focuses on cast-in-place methods and the utilization of costsaving materials. Concrete produced by the cast-in-place method has previously resulted in environmental damage and complaints. In addition, bad weather can prevent construction from proceeding. To overcome these disadvantages, a construction method has been developed to reduce construction duration-the precast construction method. Generally, precast structures have many advantages, including fast construction speed, low environmental impact, aesthetically pleasing appearance, high strength and durability, and a tendency to disrupt traffic less than structures constructed by the cast-in-place method. In a very populated, urban center or a particular location critical to the traffic network, the precast construction method allows a reduction in the construction time of up to 60-70% thus drastically reducing traffic disruption. The combination of this technology, high-performance, durable materials, and advanced earthquake technology is the recipe for success in the next generation of bridges.
