  • Total Maximum Daily Load(TMDL) is a core basin management system to assign total emissions of pollutants to unit basin and emission source within a limit of the target water quality and to secure sustainability. considering "Environment and development" together. By current technical guidance of TMDL, the water quality in the riverbed of which the target water quality is noticed, must achieve the target; and the water quality standard for evaluating achievement of the target should be prescribed as non-excessive probability quality of water on the basis of the pertinent water quality documents. Therefore, the study calculated the target water quality by each unit basin which the target water quality must be noticed through the analysis of probability for water quality documents in rivers at the time of establishing a plan, and the study evaluated the achievement possibility of the target water quality by analyzing and comparing the target water quality plan with the standard water quality to evaluate the achievement of the target water quality. As the result, applying the proposed method to Mihocheon River system, it is concluded that selected the target water quality (Each BOD 3.3mg/1 and BOD 3.0mg/1) in Miho A and Musim A is available. Of course, it showed that the target water quality: BOD 2.5mg/1 in Miho A and BOD 3.0mg/1 in Musim A, could be achieved if the small reduction in B unit area was implemented.

  • The purpose of this study was to provide the basic data needed to create more desirable psychological home environment and the prevention and relief of depression by examining the relations between psychological home environment and depression with the subjects of high school students. The study materials included standard questionnaires made up of forty two questions on psychological home environment by Dr. Jeong, Won-sik(1981), twenty one questions on depression indicators by Beck(1969). Collected data were analyzed by using SPSSWIN 10.0 Program through frequency, percentile, mean, standard deviation, t-test, ANOVA, Scheffe's test, and Pearson correlation coefficient. The main results of this study were as follows; Out of 210 perfect scores for the psychological home environment of the subjects, the mean was $140.54{\pm}11.21$, opening was $41.02{\pm}5.67$, affection was $37.59{\pm}5.80$, autonomy was $35.45{\pm}4.85$, and achievement was $26.48{\pm}6.79$. The depression of the subjects were slight, showing $13.78{\pm}9.73$, with normal condition (0-9scores) 40.0%, slight depression(10-15scores) 23.3%, mild depression(16-23scores) 20.3%, severe depression(24-63scores) 16.4%. The analyses of the relation between psychological home environment and depression of the subjects reveal that achievement-depression(r=.192, p=.000), opening-depression (r=-.296, p=.000), affection-depression(r=-.377, p=.000), and autonomy-depression(r=-.341, p=.000) has all meaningful relations. In summary, these data can be interpreted that high school students were likely to feel more depressed when they recognized their own home environment as under the burden of achievement, and to feel less depressed when they recognized it as open, affectionate, and autonomous.

  • The purpose of this study was to investigate the effect of adolescents' need on their attitudes to aesthetic surgery and clothing. Subjects were 627 middle and high school students. In this statistical analysis, SPSS 10.0 for Windows Program was used to calculate percentage, mean, and standard deviation. Also, these data were verified by Factor analysis, t-test, One-way Anova, Duncan' multiple range, Pearson's correlation coefficient, and Multiple Regression Analysis. The results of this research were as follows: Adolescents with higher need for achievement showed negative attitudes toward the secret and risk of aesthetic surgery. On the other hand, those with higher need for dominance and exhibition were in favor of the surgery and willing to have it despite its high cost and risk. Individuality of clothing was directly affected by need for achievement and dominance. Adolescents with higher need for achievement and dominance considered individuality as one of the most important factors. And sexual attractiveness of clothing had a positive correlation with both need for dominance and exhibition. Such a fact leaded that adolescents with higher need for dominance and exhibition considered sexual attractiveness as one of the most important factors, along with individuality. As a conclusion, adolescents' need play an important role in explaining the recently observed trends among adolescents in aesthetic surgery attitude and clothing attitude.

  • At the moment, in Korea, over 90% of energy resources depend on imports, and nearly 60% of electric energy is produced using fossil fuel. Therefore, the government adopted the Climatic Change Convention and has implemented the RPS system since 2012 to actively cope with the dependence on imported energy, and to grow and expand the new renewable energy industry. This study examined the performance results of mandatory supply of solar photovoltaic energy and non-solar photovoltaic energy assigned to providers and the present state after implementation of the RPS system. As a result, the achievement rate in 2012 was 64.7%. Especially, solar photovoltaic energy showed a high achievement rate of 95.7%, whereas non-solar photovoltaic energy showed a low achievement rate of 63.3% due to several problems and was highly dependent on the government. In 2013, the burden of each provider has increased due to more mandatory supply and addition of unfulfilled supply of 2012, and the separate mandatory supply of solar photovoltaic energy established for protection of the solar photovoltaic market is restricting investment. Therefore, there is a need to assign mandatory supply in consideration of the available amount of each new renewable energy.

  • Background and Objectives: The United Kingdom (UK) national standard for the closure rate for myringoplasty is 89.5% (90.6% and 84.2% for primary and revision surgeries, respectively). The average hearing gains for primary and revision myringoplasty are 9.14 dB and 7.86 dB, respectively. This study compared the myringoplasty outcomes for a single surgeon over 5 years. Subjects and Methods: Data for 68 cases were analyzed retrospectively. The outcome measures were achievement of the tympanic membrane closure and the average hearing gain or loss. Results: The overall and primary closure rates were 97% and 98%, respectively and significantly higher than the UK national standard (p=0.0210 and p=0.0287, respectively). The revision closure rate was 93%; however, it was not significantly higher than the national standard (p=0.1872). The average hearing gain was 5.18 dB. The gains for primary and revision surgeries were 5.15 dB and 5.25 dB, respectively. Conclusions: We propose that these outcomes are a result of our surgical technique, including the simultaneous use of cortical mastoidectomy in ears with discharge.
