In South Korea, some interethnic families result from prearranged marriages where 1 spouse is an immigrant. In this study, traits of children in families of interethnic immigrant marriages were studied by individual interviews of ten kindergarten teachers responsible for them and 8 observations of their preschool classes. Subjects were 21(13 male, 8 female) 3- to 5-year-old children. Results showed the diverse traits of these children : they adapted to the environment by changing and getting along, but some of them exhibited problematic behavior such as delayed language development, confused identity, and aggression. The attitude of their peers included passive reaction, discord and receptivity regarding their difference. The attitude of the teachers was a sense of responsibility and worry.

The P-ECLMS algorithm adapted the existing Post-Processing method occurs the distortion of the near-end signal at the double-talk situationt. To solve this problem, we propose the SP-ECLMS(Selective Post-Processing ECLMS) algorithm which makes the Post-Processing coefficient differently at the case of the single-talk and the double-talk. When the correlation level is not output less than 30%, the proposed algorithm output the original signal to prevent the signal's distortion.

Over-expression of a copper/zinc superoxide dismutase (Cu/ZnSOD) resulted in substantially increased tolerance to cadmium exposure in Arabidopsis thaliana. Lower lipid peroxidation and $H_2O_2$ accumulation and the higher activities of $H_2O_2$ scavenging enzymes, including catalase (CAT) and ascorbate peroxidase (APX) in transformants (CuZnSOD-tr) compared to untransformed controls (wt) indicated that oxidative stress was the key factor in cadmium tolerance. Although progressive reductions in the dark-adapted photochemical efficiency (Fv/Fm) and quantum efficiency yield were observed with increasing cadmium levels, the chlorophyll fluorescence parameters were less marked in CuZnSOD-tr than in wi. These observations indicate that oxidative stress in the photosynthetic apparatus is a principal cause of Cd-induced phytotoxicity, and that Cu/ZnSOD plays a critical role in protection against Cd-induced oxidative stress.

To propose the construction of architectural interior design and communication using graphic, web3D, it was studied the kind and character of various representation methods that can be embodied in an architectural interior design on the web, and looks into whether these ways can be adapted to an architectural interior design process. Especially, the use of the current techniques on graphic and CAD data give the most suitable effect by using the integrated data such as vector animation, an interaction of object VR(Virtual Reality), a high quality of panorama VR, and data treatment and its interaction of drawing of cad data. As a result, the single data format shows not only one image representation but also a stream of continuous operation through a change into another format. But this desired study expects that another next studies will go on interaction and integration of digital format with increase of transmission speed expected in the future, and a digital model and its practical methods.

In Jøsang's subjective logic, the fusion operator is not able to fuse three or more opinions at a time and it cannot consider the effect of time factors on fusion. Also, the base rate (a) and non-informative prior weight (C) could not change dynamically. In this paper, we propose an Improved Subjective Logic Model with Evidence Driven (ISLM-ED) that expands and enriches the subjective logic theory. It includes the multi-agent unified fusion operator and the dynamic function for the base rate (a) and the non-informative prior weight (C) through the changes in evidence. The multi-agent unified fusion operator not only meets the commutative and associative law but is also consistent with the researchers's cognitive rules. A strict mathematical proof was given by this paper. Finally, through the simulation experiments, the results show that the ISLM-ED is more reasonable and effective and that it can be better adapted to the changing environment.

An organic agriculture should be managed by mixed farming in farm unit as a closed recycling system. Due to restricted purchased of fertilizers from outside, organic farmer has to deal with limited amount of nutrient source in farm unit. Especially the supply of the essential nutrient, nitrogen, mostly depends on legumes fixing nitrogen optimizing the site-adapted crop rotation. Dynamics of humus and metabolic plant carbon and active soil carbon compartment in active and passive humuspool by rotation system was explained, and dynamics of potentially mineralizable nitrogen in organic nitrogen and biomass was discussed. It was also discussed comparison of ammonia emission, potential greenhouse effect, primary energy input, acidification potential, CO2 emission between organic and conventional farming, the nitrate-nitrogen dynamic in the soil profile by organic, integrated and conventional farming system. In conclusion, it was suggested for Korean Organic Agriculture that the importance of legumes and green manures in rotation system for increase/maintenance of soil ferfility, and was pointed out the need of investment for environment impact of Korean organic farming implement.

Private participation on public infrastructures projects is being promoted by governments of several developing countries, among them Colombia. As a result, several advantages such as service delivery efficiency, technology application and faster execution of the projects have been recognized. Hence, the Colombian Government is looking for schemes that allow the private investment in projects like hospitals, schools, prisons and public edification. In this paper, experiences in PPP from other countries were analyzed and adjusted to the Colombian environment. As a result, a model adapted to Colombia is presented, based on a well-developed case from Spain. The awarding process is defined by economic criteria, previous compliance of minimum technical exigencies. Once the infrastructure is operating, contractual periodical payments will be done, based on the performance of the facility.

Purpose: This study is to research how New-Hanok R&D technologies of first stage are appearing and adapted to the New-Hanok style public buildings, especially in Daycare Center in Sunchang-gun, Korea. Unlike Hanok houses, public buildings which has special needs for the public and restricted by laws and regulations need not only new system of law incentives but also new components of New-Hnaok R&D technologies used only in Hanok house. Method: For this purpose, we checked the drawings for Daycare Center in Sunchang-gun. The drawings have been changed 6 times for the purpose of adopting New-Hanok R&D technologies of first stage and actual needs for current laws and regulations for public buildings and it reveals not only the possibilities for adapting new technologies in New-Hanok but also meetings the current and public needs for public buildings. Result: The result of this study as follows. Approximately 40-50 percent of New-Hanok R&D technologies in the first stage are adapted in Daycare Center in Sunchang-gun, and this means there are limitations in adapting New-Hanok R&D which are mainly for the Korean style houses. The main reasons are the costs still remaining high and lacking in confidence for using traditional structures and materials still under verification. Some are changed and proposed in another solutions suitable for public buildings as like truss structure system in roof.

Objectives: The purpose of the study was to investigate the perception and practice of the infection control by empowerment in the dental hygienists. Methods: A self-reported questionnaire was filled out by 200 dental hygienists in Gyeongbuk from January 3 to February 20, 2013. Data were analyzed by SPSS 12.0 program. The instrument of impowerment was adapted from Spreitzer and consisted of 12 questions including meaning(4 questions), competency(4 questions), self-decision(4 questions), and impact(4 questions). Impowerment was score by Likert 5 scale and higher score means higher impowerment. The instrument for hand washing recognition and practice was adapted from Kim and consisted of hand washing(5 questions), personal protective clothing management(5 questions), contaminated appliance management(3 questions), sterilization(3 questions), and infection control environment(8 questions). The empowerment instrument was score by Likert 5 scale and the mean was 3.83 points. Based on 3.83, infection control recognition and practice were divided into upper group and lower group. Cronbach alpha was 0.951 in empowerment, 0.931 in recognition, and 0.924 in practice in the study. Results: Based on the average points of 3.83, the groups were divided into two groups including upper group and lower group. The upper group showed higher score in hand washing than the lower group. In the protective clothing management, the upper group changed the mask at one-hour interval(p<0.001). Conclusions: In the viewpoint of empowerment, it had a significant influence on the perception and practice of the dental infection control in the dental hygienists.
