In this paper, we analyzed the electric characteristics of the OLEDs device of which anode ITO has been treated with the oxygen plasma. We fabricated the basic three-layer structure (ITO / AF / $Alq_3$ / $Cs_2CO_3$ / Al) device, analyzed how the oxygen plasma treatments of the ITO surface affects to the electrical characteristics of OLEDs. We also produced a four-layer structure device (ITO / AF / TPD / $Alq_3$ / $Cs_2CO_3$ / Al) with the oxygen plasma treatment. From the comparative analysis to the devices, we confirmed following results. The three-layer structure OLEDs device with oxygen plasma treatment has better characteristics than the device without the treatments; maximum luminance, luminous efficiency, and external quantum efficiency are improved approximately 151 [%], 126 [%], and 175[%], respectively. Also, the electric characteristics of the four-layer structure device with oxygen plasma treatment are improved comparing to the characteristics of the three-layer structure device with oxygen plasma treatment; maximum luminance, luminous efficiency, and external quantum efficiency are improved approximately 144 [%], 115 [%], and 124[%], respectively.

This case study investigated the assessment and treatment of bilingual children using a 4.5 year old bilingual child. We also compared treatment methods for bilingual children in the U.S. and in Korea, respectively. Given the lack of unbiased assessment tools, it was difficult to evaluate the child properly. In addition, the study of the linguistic characteristics of bilingual children have not been researched extensively in Korea. As a result, there were limitations in assessing the child. However, once all requisite information had been gathered, he was assessed as a bilingual child with specific language impairment (SLI) and his skill in both languages was considered equivalent. During treatment sessions, the child exhibited diverse linguistic characteristics and interesting error patterns which were not evident in monolingual SLI. However, it was difficult to assess whether the error patterns exhibited by the subject were attributable to his own bilingual characteristics or not. This was further complicated by the lack of previous research on the bilingual child's linguistic characteristics. His progress differed from one area to another. Furthermore, we illustrated some of the limitations in assessing bilingual children and proposed several considerations that should be met before treatment is initiated.

The purpose of this experiment was to study the effect of varying levels of tryptophan on the performance and carcass character of broiler. Trial 1: Ninety-six, five-week-old male Hubbard chickens, average weight 1.97 kg, were used in the trial. All birds were allocated into 3 treatments of 32 birds each. Each bird was kept in an individual cage. The trial period was 3 weeks. Treatment 1: Tryptophan content 0.198%. Treatment 2: Tryptophan content 0.228%. Treatment 3: Tryptophan content 0.258%. Trial 2: Ninety-six, three-week-old male Hubbard chickens, average weight 1.23 kg, were randomly distributed into the following two treatments. Each treatment had 48 birds. Treatment 1: Tryptophan content 0.167%. Treatment 2: Tryptophan content 0.198%. Trial 3: Ninety-six, twoweek-old Hubbard chickens, average body weight 0.72 kg, were used in this experiment. There were three treatments as follows. Treatment 1. Tryptophan content 0.136%. Treatment 2. Tryptophan content 0.167%. Treatment 3. Tryptophan content 0.198%. The result of Trial 1 showed that the feed intake, performance, and carcass characteristics were not influenced by tryptophan content in the diet which between 0.198% and 0.258% (p>0.05). There was no significant difference (p>0.05) in feed intake in either treatment in Trial 2. However, weight gain, feed conversion efficiency, and most carcass characteristics in the 0.198% treatment were significantly better (p<0.05) than in the 0.167% treatment. There was a trend that feed intake increased with increasing level of tryptophan, but there was no significant difference in Trial 3. The weight gain and feed conversion efficiency were significantly reduced for the broiler in the 0.136% treatment. This series of experiment showed that broilers need about 0.198% of tryptophan.

This study conducted a result analysis on operation of 26 Rural Community Sewage Treatment Plant (RCSTP) newly constructed in Yeong-yang, Bong-hwa and An-dong areas which are located at the upper region of An-dong Dam and Im-ha Dam. Based on operation result, an analysis on characteristics of sewage in each area and the treatment efficiency of the installed treatment process was conducted. The result of analysis on characteristics of sewage has shown the difference in concentration of the sewage according to area characteristics. Sewage in areas with frequent occurrence of agricultural water and livestock wastewater had high concentration. It is important to select the most suitable treatment process when selecting a treatment process for RCSTP according to properties of sewage in each area. As a result of operation, the disposal efficiency for organic matter and suspended solids was stable with less fluctuation, but the disposal efficiency for nitrogen and phosphorus showed high fluctuation. This signifies that it is necessary to pay attention to operation condition management of nitrogen and phosphorus when operating RCSTP.

Vertically-aligned and uniformly-distributed CuO nanowires were formed on copper-coated Si substrates by wet chemical process, immersing them in a hot alkaline solution. The effects of hydrogen plasma treatment on the field emission characteristics of CuO nanowires were investigated. It was found that hydrogen plasma treatment enhanced the field emission properties of CuO nanowires by showing a decrease in turn-on voltage, and an increase in emission current density, and stability of current-voltage curves. However, the excessive hydrogen plasma treatment made the I-V curves unstable. It was confirmed by XPS (X-ray Photoelectron Spectroscopy) analysis that hydrogen plasma treatment deoxidized CuO nanowires, thereby the work function of the nanowires decreased from 4.35 eV (CuO) to 4.1 eV (Cu). It is thought that the decrease in the work function enhanced the field emission characteristics. It is well-known that the lower the work function, the better the field emission characteristics. The results suggest that the hydrogen plasma treatment is very effective in achieving enhanced field emission properties of the CuO nanowires, and there may exist an optimal hydrogen plasma treatment condition.

The primary purpose of this study was to provide the basic materials for C.V.A inpatients' actual use of medical service at the hospital with both the western and oriental medical department and the attitude on cooperative treatment. The results of this study were as follow: First, the subjects' general characteristics including job, monthly mean income and age made statistical differences to their pathological characteristics such as part of primary paralysis, detailed name of disease and cause of elicitation. Second, their general characteristics including religion and job produce statistical difference to their actual use of medical service, like medical institution form, term of treatment and type of medical institution at first-aid. Third, through the awareness of cooperative treatment system, the effect of C.V.A treatment and the shorten of the C.V.A treatment term were higher at oriental medical department inpatients and cooperative treatment serviced inpatients than western medical department inpatients and cooperative treatment non-serviced inpatients. Fourth, the biggest problem on current dual medical system is increase medical expenses and the biggest reason on not vitalized cooperative service is prejudice of both parts.
