Combined sewer system (CSS) has been built in the most urban areas across the nation. During dry weather conditions, CSS works fine. But during heavy rain storms, combined sewage frequently overflows into the stream. This study simulated the hydrologic cycle and pollutant loads (BOD, SS, TN and TP) in the Mokgamcheon watershed considering combined sewer overflows (CSOs). PC storm water management model (PCSWMM) was used for continuous simulation and CSOs are considered using the flow divider. Sensitivity analysis, calibration and verification for water quantity and quality are carried out. To verify CSOs, field measurements of CSOs are compared with simulated results. As a result, 41.3% of precipitation flows into the stream directly and 1.1% of water supply flows into stream as CSOs. 6.5% of BOD total loads, 12.0% of SS, 13.6% of TP, and 29.2% of TN are from CSOs. This result will be effective to the integrated watershed management for sustainability.

Since 1990s, the use of Complementary and Alternative Medicine(CAM) has been rising rapidly all of the world. In 1983, WHO recommended that the traditional medicine actively be utilized. At the end of 20th century, as chronic and intractable diseases increased in western countries, traditional medicine has attracted considerable attention. COWM shows possibilities of new approaches for these intractable diseases. Thus, we try to show our proper approach of COWM through the international comparative study. In order to fulfill the objectives, we applied the following methodology: 1) Literature review on previous study, 2) Local survey using self-administered questionnaire, and 3) FGI(Focus Group Interview) with local experts. The results were as follows : Three Asian countries, China, Korea and Taiwan, are very active in implementing COWM policy. Japan, however, has independent system of unified medicine. In regards to the combined care policy and system, China has the most advanced COWM system among four countries. In respect to combined care education, it is needed to increase the COWM education contents and the amount of cross educational curriculum. Based on the current COWM system, Chinese, Japanese and Taiwanese doctors can prescribe both oriental and western drugs. But, Korean medical law prohibits western doctors and oriental doctors from prescribing the counterpart´s medicine. So, the revision of current medical law is urgent for COWM in Korea. And when it comes to patient satisfaction, more than fifty percent responded positively in China, Korea and Taiwan. To achieve the goal of COWM ; 1) mutual understanding and recognition of COWM is essential. 2) institutional and legal support system for COWM is desperately urgent. 3) possible international collaboration and cooperation should be sought to untangle these complex cultural dilemmas.

Augmented reality is a novel human-machine interaction that overlays virtual computer-generated information on a real world environment. It has found good potential applications in many fields, such as training, surgery, entertainment, maintenance, assembly, product design and other manufacturing operations. In this study, a smartphone-based augmented reality system was developed for the purpose of monitoring and managing injection molding production lines. Required management items were drawn from a management content analysis, and then the items were divided into two broad management categories: line management and equipment management. Effective work management was enabled by providing those working on the shop floor with management content information combined with the actual images of an injection molding production line through augmented reality.

The rapid growth of engineering technology and the emergence of systemized and large-scale engineering systems have resulted in complexity and uncertainty throughout the lifecycle activities of engineering systems. This complex and large-scale engineering system consists of numerous components, but system failure can be caused by failure of any one of a number of components. There is a real difficulty in managing such a complex and large-scale system as a part. In order to efficiently manage the system and have high reliability, it is necessary to structure a system with a complex structure as a sub-system. Also, in the case of a system in which cause of failures exist at the same time, it is required to identify the correlation of the components lifetime and utilize it for the design policy or maintenance activities of the system. Competitive risk theory has been used as a theory based on this concept. In this study, we apply the competitive risk theory to the models with combined structure of series and parallel which is the basic structure of most complex engineering systems. We construct a competing risks model and propose a mathematical model of net lifetime and crude lifetime for each cause of failure, assuming that the components consisting a parallel system are mutually dependent. In addition, based on the constructed model, the correlation of cause of failure is mathematically analyzed and the hazard function is derived by dividing into net lifetime and crude lifetime.

While commercialization of IoT technologies in the safety management sector is being promoted in terms of industrial safety of large indoor businesses, implementing a system for risk management of small outdoor work sites with frequent site movements is not actively implemented. In this paper, we propose an efficient dynamic workload balancing strategy which combined low-power, wide-bandwidth (LPWA) communication and low-power Bluetooth (BLE) communication technologies to support customized risk management alarm systems for each individual (driver/operator/manager). This study was designed to enable long-term low-power collection and transmission of traffic information in outdoor environment, as well as to implement an integrated real-time safety management system that notifies a whole field worker who does not carry a separate smart device in advance. Performance assessments of the system, including risk alerts to drivers and workers via Bluetooth communication, the speed at which critical text messages are received, and the operation of warning/lighting lamps are all well suited to field application.
