Objectives The purpose of this study is to investigate effectiveness of the Ha-Taedok treatment and discuss how to improve the Ha-Taedok method Methods We analyzed the medical records of 20 children who were treated by Ha-Taedok method. 20 questionnaires were administered to the mothers of those children and statistically analyzed by using PASW Statistics 18. Results The children who were treated by Ha-Taedok method weighed at birth ranged from a minimum of 2.7 kg to a maximum of 3.86 kg, and the children's weight after treated by Ha-Taedok method were varied from a minimum of 2.8 kg to a maximum of 4.7 kg. The Ha-Taedok treatment was initiated to children from 3 to 23 days after their birth. 15 out of 20 mothers of the children treated by the Ha-Taedok method were satisfied with Ha-Taedok method (75%). All of them answered that they were willing to repeat the treatment to their children again or recommend the treatment to others. 10 out of 20 mothers told that the main factor/point for improvement of Ha-Taedok method was publicity. Conclusions If the effectiveness of Ha-Taedok method is scientifically proven and recommended, the scope of Ha-Taedok method for newborn infants will be widely used.

Finite element program(ANSYS) estimated thermal deformation quantity in high frequency heat treatment process of a machine tool fred drive system slideway and apply deformation quantity in roughing process. Having processed the heat treatment minimizing methods of the quantity of deformation heat treatment process. Having done heat treatment with high frequency after taper processing with considering the existed heat treatment generating the quantity of deformation, existed quantity of deformation can be reduced down to 80%, consequently productivity and material saving can be achieved. When high frequency heat treatment finite element method estimated deformation quantity at difference temperature and time, it is progress at cost don and saved time.

Purpose of this research is deducing optimum pretreatment method of electric arc furnace slag from comparing and investigating the properties of electric arc furnace slag and electric arc furnace slag concrete by existing pretreatment method and surface pretreatment method being used by this research. Besides, as the surface pretreatment method, the method of naturally drying for 6 hours after impregnating with an inorganic type silica solution for 1 day was used. From the results, comparing the hot water treatment method, surface treatment method being used by this research is more effective. Therefore, it is judged that surface treatment method is more effective in the decrease of expansibility of electric arc furnace slag and practical use.

In this work, molybdenum oxide films were fabricated by heat-treatment method. Fundamental surface characteristics of molybdenum oxide films were investigated using XRD and Raman spectroscopy. From the results, the optimum MoOx films could be obtained under the conditions of thermal treatment temperature of $550^{\circ}C$, oxidation time of 30 minutes and oxygen flow rate of 250sccm. The thermal treatment method offers a simple and effective route for the synthesis of uniform $MoO_3$ films.

The tunnels that longer than 2km which have been recently constructed have serious noise problems resulting from the friction of vehicle wheels and pavement. In special, concrete pavement inside tunnels with a closed characteristic increases discomfort due to the traffic noise and the dust of pavement pollutes the air in tunnels. Therefore, it is urgent that we find out ways to cope with. This study purported to reduce noise inside tunnels covers the investigation of various pavement surface treatment methods adapted in developed countries, the analysis of the effect in noise reduction and construction methods and cases. The surface treatment method for silent pavement in tunnels reduced noise to 5dB (A)~10dB (A). Aggregate treatment method is evaluated the most appropriate method in that, related with other surface treatment method, it reduces noise and improves skid resistance. It is necessary for us to introduce equipments and design and rearrange of specification for the development of the silent pavement method in Korea.

Development on the mechanical properties of steel sheet for the automobile body panel is very important in the BAF(Batch annealing furnace) annealing process. Because of the heat treatment method in the BAF, mechanical properties was decided on the heat treatment method of the coil. So, we tested on the development of mechanical properties according to heat treatment method at the annealing furnace using the Ax(H$_2$75%, $N_2$25%) atmospheric gas and the HNx(H$_2$4%, $N_2$96%) atmospheric gas. As a result of several investigations. We confirmed the following characteristics ; mechanical properties was changed under the influence of the annealing cycle, the heat treatment method and the atmospheric gas. And, elongation in the HNx BAF was better than the Ax BAF. Finally, most important thing in the BAF is using of proper annealing cycle in order to get a good quality.

For the Purpose of this study, were researched the optimum condition preconditioning condition of orient tobacco leaves . The loss of 3-methyl pentanoic acid (3-MP) component of BASMA leaves in the treatment process amount to about 60% , but the loss of 3-MP At the optimum conditions of BASMA CTC treatment, the temperature was 45-$65^{\circ}C$ and the treatment time 25-35 minutes. And further, the physical properties of BASMA after CTC treatment was remarkably similar to the control's. Since VTC minimized the loss, it is suggested that CTC method should be changed by VTC method.

In this paper, the effect of cellulase treatment was evaluated by means of phenol-sulphuric acid method. This method was performed by determining sugar liberation in the treatment bath with the amount expressed in glucose equivalent. As compared with conventional method, the measurement of amount of sugar liberated gave a more reliable and accurate result than the weight loss method. It was found that although the weight loss of cellulose became negligible when the treatment was done under agitation-free condition, the amount of sugar liberated was still readily measurable.
