  • The purpose of this study is to analyze the effect of the results of a nationwide academic evaluation of middle schools and high schools on apartment prices in Ulsan City by using a hedonic pricing model. The results of the middle school and high school achievement test, the College Scholastic Ability Test (CSAT) score for high school, the national united evaluation score, and the number of successful applicants to prestigious universities have a significant effect on the apartment price formation with a positive relationship. In addition, different kinds of academic evaluation score have asymmetric effects on apartment price determination. The results of the high school achievement evaluation are more important than the results of the middle school achievement evaluation in the apartment price determination. Among the achievement evaluation results, the ratio of the students with the higher education level is more important than the ratio of the students with the lower basic education level. Furthermore, the CSAT score for Natural Sciences is more important than the CSAT score for the Humanities course.

  • This study examined color trends per season and differences in color utilization between seasons with a focus on hue and tone, based on men's collections. Collected colors classified as hue and tone were subject to frequency and cross analyses according to the study subject. The study results as follows. The hues most frequently used for men's wear in S/S season were red and purple. The red hue was most frequently used even in F/W season. As for tone, blackish tone was found to be prominent, irrespective of season. The cross analysis revealed a significant difference in the main colors' hue and tone utilization between S/S and F/W seasons. In addition, more diverse tones were found to be used in S/S season than F/W season. The hue and tone trends seen in main colors of men's wear in S/S season were analyzed per year, blackish tone and light grayish tone accounted for the majority among all tones. In terms of men's wear in F/W season, blackish tone was frequently used as the main tone, while other tones were found to have a low usage frequency.

  • Here we report a previously unrecorded species of Korean Allium (Alliaceae) from Geomundo, Yeosu-si, Jeollanam-do. This taxon, A. pseudojaponicum Makino which has been known to distribute only in the southern part of Japan up to date, is easily distinguished from A. thunbergii G. don by lustrous evergreen leaves and lateral scapes as well as chromosome number (2n=32). The common name, 'Gaet-bu-chu', was newly given considering the property of habitat, which is the dry and rocky grasslands facing to the sea in Korea and Japan. In this study, we redescribe morphological characters, and provide illustrations of habit as well as photographs of habitat.

  • A benthic microbial fuel cells(BMFC) is fuel cell using electricity produced by decomposing organic matter in a sea or a lake. In this study, we used a gas diffusion layer (GDL) of a polymer electrolyte fuel cell (PEMFC) as a BMFC electrode to find out the operation conditions with high performance. The performance of BMFC was increased as resistance of external resistor increased. It was possible to maintain the performance by avoiding the increase of the contact resistance with the electrode due to corrosion of the lead wire in seawater. The bubble generator was able to increase the maximum power density by more than 2 times and the optimum operating temperature was $40^{\circ}C$.

  • There have been constant requests for urgently recruiting professionals in the archives to establish archival management systems by reflecting public institutional feature as well as reinforcing expertise and independence of them. However, it is true that some even adequate professional manpower haven't been secured at each level of public institutions due to ambiguous standards for the placement of professionals in the field of records management followed by the current [Public Records Management Act]. Thereupon, this study is to create records management task model for the archival management institutions with the workload of records management induced by the model, and to present reasonable scale of workforce to deal with the assignment. Moreover, here is shown which professional staff should be allocated for better efficiency and systems to carry out the task of records management in each relevant institution.

  • In this study, from 2004 to 2008 influents and discharging effluents from 241 municipal public sewage treatment plants were surveyed. Statistics including average, Coefficient of Variation (CV) and Coefficient of Reliability (COR) for each season, time series analysis for removal efficiency and water quality of effluents, and a comparison of the effluent standards in Korea and other countries were presented. The average concentrations of TN and TP in influents. during winter season were 32.6 and 3.78 mg/L and during other season were 30.8 and 3.61 mg/L in 2008, respectively. The average TN concentration on the basis of the maximum monthly concentrations in the effluents during winter season ranged from 14.2~17.4 mg/L and during other season ranged from 12.2~14.8 mg/L. The TP concentration in the effluents depending on the each season was no big difference. TN removal efficiency decreased from Jan. to Feb. and TP removal efficiency decreased in Jan., Jun and July. Maximum COR during winter season were 0.61 but the COR for TN and TP during other season ranged from 0.96~1.48 and 1.09~1.81, respectively, due to big difference in the standard for TN and TP in effluents depending on the season. TN and TP standards for effluent of sewage treatment during winter season in Korea was much higher than those in other countries. Therefore the lower effluent standards during winter season is essential for the water quality improvement.

  • In this study, we proposed an anti-reflective nano-structure to improve the photoresponsivity of AlGaN UV photodiode that can be used as a receiver in a solar blind UV optical communication system. The anti-reflective nano-structure was fabricated by forming Ni nano-clusters on SiO2 film followed by etching the underneath SiO2 film. A sample with the anti-reflective nano-structure exhibited lower surface reflection along with less dependency on the wavelength in comparison with a sample without the nano-structure. Finally, a UV photodiode was fabricated by applying an anti-reflective structure produced by heat-treating a 2 nm-thick Ni layer. The photodiode fabricated with the proposed nano-structure exhibited noticeable improvement in the photoresponsivity at the wavelength range from 240 nm to 270 nm in comparison with the same photodiode with a SiO2 film without the nano-structure.
