It is a fundamental experiment to use blast-furnace slag in solidification/stabilization process. The compressive strength and leaching test of Pb and Cr doped samples were evaluated and the effects of heavy-metal ions on the hydration of slag was investigated. Sodium silicates(5wt%) was added as alkali-activator and the effects of replacing a part of slag with flyash or gypsum was also discussed. Pb ion was solidified by encapsulation of matrix. In of slag${\pm}$gypsum binder microstructure was densified by accelerating to form AFt/AFm phase and compressive strength was improved resulting in reducing leaching amount of Pb ion. Cr ion was solidified by substituting with Al ion in aluminate product. Slag+fly ash binder improved compressive strength and decreased leaching amount of Cr ion.

The effects of heat treatment on room temperature ferromagnetism of Co-doped ZnO were investigated with a (ZnO 20Å/Co x Å)20 multilayer structure where x = 1.5, 3, 4.3, 6 and 9 Å. As the thickness of the Co sub-layer increased, the ZnO/Co multilayer changed its magnetic state from diamagnetism at Co 1.5 Å and 3 Å to weak ferromagnetism at Co 4.3 Å and strong ferromagnetism at Co 6 Å and 9 Å. The heat treatment,in a vacuum at 400°C, changed the diamagnetic property into a ferromagnetic one, resulting in room temperature ferromagnetism for all Co sub-layer thicknesses. The improvement in ferromagnetism could be ascribed to the exchange coupling between dispersed Co atoms through XRD, optical transmittance and TEM analysis.

Iron-bearing cold bonded pellets using blast fumace slag with various activators were prepared and cured at different conditions. The specimens were evaluated by UTM analysis and compared with pellets using ordinary Portland cement. To clarify the hardening mechanism of slag binder, XRD, DTA, Calorimeter, SEM and other analyses were performed. Hydration product identifications and compressive strength measurement revealed that if activators and curing conditions were properly chosen, Cement can be replaced with slag binder in cold bonded pellet preparation.

In order to develop electrochemical deposition machine, we investigated the effects of some key design factors on the electrochemical deposition process, for example, current density, electrode agitating and electrochemical solution circulation. Deposition rate is increased with the current density and circulation. Thickness uniformity shows rather complex behavior, that is, it is improved with slow circulation at 0.03 A/㎠ current density while at 0.04 A/㎠, faster circulation shows better thickness uniformity.

This experiment aimed to establish adequate fruit thinning techniques by comparing and investigating fruit productivity and changes of fruit quality with thinning times and thinning methods. Satsuma mandarin(Citrus unshiua Marc.) cv. ‘Miyagawa Early was used and treatments were 11, the alternate whole branch fruit(buds) thinning(AWFBT), the partially whole tree fruit thinning(PWTFT) and the foliar spray of the chemical fruit thinning agent(FSCFTA:ethychlozate) etc. from the middle of June to early in Sept. The results were as follows ; Ⅰ. The earlier fruit-thinning times was, the higher the ratio of marketable fruit yield was, and the AWTFT and PWTFT in the middle of May, the FSCFTA and PWTFT in June were effective to increase the ratio of marketable yield in this order 2. Thinning of bud in the middle of May required about 50min. to eliminate buds from a tree, it's a big problem. In contrast, FSCFTA(ethycholzate 50mg/l + ethrel 20mg/l) required 3.1min, the shortest working hours for getting rid of buds and the AWFBT was more effective than the PWTFT because of saving the labor efforts to pick and thin fruit. 3. Thinning and FSCFTA methods could be able to harvest fruit earlier and also was good in rind color, but soluble solid and juice sac thickness which indicate the interior quality were not significant. It was thought that this is because leaf-fruit ratio at the harvesting time due to fruit thinning and FSCFTA treatments was less than 25. But in case of sugar-acid ratio, that of the AWFBT treatments showed a little more increse than that of the PWTFT. 4. The number of fruit set in following year was much more in earlier fruit thinning treatments and the AWFBT than in late thinning and PWTFT treatments, respectively. 5. From these results, it was considered that the tree bearing too many flowers in more effective to put the AWFBT at least by the end of June for increse of the ratio of marketable fruit yield, quality fruit and the prevention of the alternate bearing.

인적오류로 인한 철도사고 예방을 위한 Framework 개발

- Recent incidents of railway derailments and staff fatalities have highlighted the persistent issue of railway accidents. Despite advancements in high-speed trains and automated, complex railway systems, operations and maintenance still heavily rely on human workers. Human error remains a significant factor in railway accidents, underscoring the critical need for system improvements and advanced safety management frameworks to prioritize safety and mitigate human error-related risks. This study aims to develop an advanced framework for preventing railway accidents caused by human errors. The research encompasses four major areas: (1) the development of a system for collecting and analyzing data on railway workers, including health information, work hours, camera footage, and biometric data such as blood pressure and heart rate; (2) the implementation of real-time safety support systems for railway workers using smart helmets and paperless tools; (3) the development of an integrated management system to evaluate and predict human errors through task analysis, identify safety and non-safety tasks, and quantify impact factors, similar to human reliability analysis; and (4) the development of a multiuser virtual training system for joint emergency response training; this system will enable multiple railway workers to train simultaneously, with real-time comprehensive analysis of training effectiveness based on the biometric signals of trainees.

- A quantitative investigation was conducted to assess the effects of train speed and operating environment on signal recognition rates of high-speed train drivers in Korea. Given the high proportion of accidents linked to human error, particularly signal misrecognition, simulator-based experiments were performed with twenty licensed drivers under realistic operating conditions. Speeds of 250, 300, 350, and 400 km/h, various environmental settings (day/night, clear, snow, rain, and tunnel), and signal colors (green and red) were examined. Drivers responded using color-matched buttons, and recognition rates were recorded for each condition. Results indicated that higher speeds reduced signal recognition accuracy, with tunnels and adverse weather further intensifying this decline. Signal color was also influential, with green signals recognized nearly 30% more accurately than red, reflecting human visual sensitivity. Unlike prior survey-based studies, precise experimental data were provided, revealing vulnerability patterns that may inform engineering standards, driver training, and policy for railway safety in Korea. The findings highlight the necessity of continuous empirical evaluation as train speeds and operating environments advance.
