In Korea, Total Maximum Daily Loads(TMDLs) has been enforced to restore and manage water quality in the watersheds. However, some assesment of implementation plan of TMDLs showed that the achievement of the target water quality is not related to the proper allocation loads because difference of flow duration interval. In the United States, the discharge loads are determined by water quality modeling considering standard flow conditions according to purpose. Therefore, this study tried to develop the allocation method considering economical efficiency using water quality model. For this purpose, several allocation methods being used in the management of TMDLs is investigated and develope an allocation criteria considering regional equality and uniformity. Since WARMF(Watershed Analysis Risk Management Framework) model can simulate the time varying behavior of a system and the various water quality variables, it was selected for a decision support system in this study. This model showed fairly good performance by adequately simulating observed discharge and water quality in Miho watershed. Furthermore, the scenario simulation results showed that the effect of annual average water quality improvement to remove 1kg BOD is more than 25 times, even if point pollutants treatment facility is six times more expensive to operate than non-point pollutants treatment facility.

Purpose: By analyzing factors related to suicide ideation of Korean middle and high school students, the purpose of this study was to multi-dimensionally understand suicide ideation of Korean middle and high school students and arrange the plans to prevent suicide. Methods: This study used and analyzed the data on ‘The 3rd (Year2007) Korea Youth Health Risk Behavior Web-based Survey (KYHRBWS)' conducted by the Korea Centers for Disease Control and Prevention. In this study, we analyzed 74,698 respondents in total. SPSS 12.0 Program was used to analyze the survey. Descriptive statistics, Chi-Square Test and multivariate logistic regression were also used as research methods. Results: 23.8% of the Korean middle and high school students had suicide ideation during the last one year. Girls had higher possibility of suicide ideation by 1.51 times compared to boys. Students with poor academic achievement had more suicide ideation. In terms of health characteristics, students who perceived themselves as not healthy, and students with short weekday sleeping hours, more drinking experience and more smoking experience had more suicide ideation than others. Furthermore, students who perceived themselves as overweight or obese had more suicide ideation than other students. In terms of mental characteristics, students with high level of stress, low level of happiness and depression had more suicide ideation. Conclusion: As a result of this study, we found out that the factor that had the biggest influence on suicide ideation of Korean middle and high school students was depression. Consequently, active supports and policies to decrease suicide ideation of Korean middle and high school students are necessary. Therefore, active interviews, education for suicide prevention, and periodical screening inspection should be introduced in schools.

When Hart Crane′s poem cycle The Bridge was published in 1930, a group of influential reviewers accused Crane of immaturity, sentimentality, and lack of focus. They condemned crane′s wayward, fuzzy mysticism as backwards-looking and self-defeating. Even sympathetic critics, such as Harold Bloom, have consistently portrayed Crane′s poetry as the pyrotechnic final fizzle of late romanticism. These persistent, public reservations, however, have not prevented an impressive proliferation in secondary literature concerning Crane since the late 1960s. His promiscuity, alcoholism, erratic behavior, relative poverty, tragic death, and total commitment to art have since earned him the labels of New World Rimbaud and proto-Beat. His colorful career thus explains in part his retrospective fame. Nevertheless, living hard and dying young do not guarantee artistic immortality. This article poses questions as to why Crane has mattered so much to subsequent generations of U.S. readers and what these readers find so compelling in his poetry. The answer, I would argue, lies in Crane′s idiosyncratic use of language. Far from striving for transparency, he writes in an inimitably obstructive, artificial manner. There is something seductive and absurd in his wild use of words here, I would further argue, we discover the reason behind both Crane′s enduring appeal and his supposed inadequacy as a writer. Crane did "torture" syntax, semantics, and conventional associations, not because he saw his unusual language as an eccentric mannerism but because he saw it as a tool in the service of constructing a "myth of America" and reintegrating the human and divine. Understanding thy he considered this to be the case clarifies Crane′s achievement and illuminates why his work still seems so relevant today.

Objectives: This study identified how personal characteristics, family environment, governmental policy for the prevention and cessation of smoking might influence on adolescent smoking. Methods: This study used data from the 2006 Korea Youth Risk Behavior Web-based Survey of 71,404 middle school and high school students, giving a response rate of 90.9%. We selected 61,508 adolescents subjects of the final analysis without missing data on independent variables and dependent variables which are used in this study. This study used $\chi^2$ tests and logistic regression models. Variables were added to the regression model in three groups using a hierarchical approach.Results: Adolescents were significantly more likely to become current smokers if they were boys, were in a higher grade, and had lower academic achievement. Adolescents experiencing stress and depression were associated with increased risk of current smoking. Adolescents with single parents or students of non-living with parents comparing with students of living with parents showed the high possibility of smoking. Lower father's education was associated with increased likelihood of current smoking. Adolescents who were exposed to smoking at home were more likely to smoke. Adolescents without contacting with the antismoking media campaign was associated with increased likelihood of current smoking. Conclusion: Promoting antismoking media campaigns targeted at adolescent is required, and the smoking prevention education which are proper for subjects are required. Proper plans which could decrease the exposure of secondhand smoking should be established.

The superior properties of ZnO such as high exciton binding energy, high thermal and chemical stability, low growth temperature and possibility of wet etching process in ZnO have great interest for applications ranging from optoelectronics to chemical sensor. Particularly, vertically well-aligned ZnO nanorods on large areas with good optical and structural properties are of special interest for the fabrication of electronic and optical nanodevices. Currently, low-dimensional ZnO is synthesized by metal-organic chemical vapor deposition (MOCVD), molecular beam epitaxy (MBE), thermal evaporation, and sol.gel growth. Recently, our group has been reported about achievement the growth of Ga-doped ZnO nanorods using ZnO seed layer on p-type Si substrate by RF magnetron sputtering system at high rf power and high growth temperature. However, the crystallinity of nanorods deteriorates due to lattice mismatch between nanorods and Si substrate. Also, in the growth of oxide using sputtering, the oxygen flow ratio relative to argon gas flow is an important growth parameter and significantly affects the structural properties. In this study, Phosphorus (P) doped ZnO nanorods were grown on c-sapphire substrates without seed layer by radio frequency magnetron sputtering with various argon/oxygen gas ratios. The layer change films into nanorods with decreasing oxygen partial pressure. The diameter and length of vertically well-aligned on the c-sapphire substrate are in the range of 51-103 nm and about 725 nm, respectively. The photoluminescence spectra of the nanorods are dominated by intense near band-edge emission with weak deep-level emission.
