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.

본 연구는 공기업을 중심으로 다면평가제도의 선행요인이 평가효용성에 미치는 영향과 평가효용성이 조직성과에 미치는 영향을 파악하고 평가제도의 사전교육정도에 따라 평가효용성에 미치는 영향에 차이가 있는지를 알아보고 궁극적으로 피평가자가 인식하는 평가효용성이 조직성과에 어떠한 영향을 미치는지 4가지 관점에서 연구하였다. 연구 결과 선행요인인 평가자 신뢰성, 최고경영자의 지지는 평가효용성에 유의한 영향을 미치고 있으나 평가준거는 유의적이지 못하였다. 사전교육의 정도에 따라 선행요인과 평가효용성 간에 조절효과가 있는지를 검증한 결과 평가자 신뢰성은 조절효과가 있는 것으로 판명되었다. 그러나 평가준거, 최고경영자의 지지는 조절효과가 없는 것으로 나타났다. 결과적으로 본 연구의 평가효용성이 선행요인의 영향을 받아서 조직의 성과 즉, 조직몰입도, 직무만족도, 자기계발기회, 조직활성화에 직접 또는 간접적으로 영향을 미치며, 사전교육이 부분적으로 조절효과가 있는 것으로 확인할 수 있었다.

본 연구는 간호학과 신입생들의 성격유형과 학습스타일, 학업성취도 간의 상관성을 탐구하기 위해 시행되었다. 간호학과 신입생 144명을 대상으로 2018년 3월 6일부터 5월 18일 까지 자료를 수집하였다. 결과 분석은 빈도와 백분율, 평균 및 표준편차, t-test와 ANOVA, Chi-square test 그리고 Pearson correlation coefficient로 확인하였다. 연구 대상자의 성격유형은 외향적 성향(58.3%)이 내향적 성향 보다 많았으며 감각적 성향(66.7%)과 감정형(77.8%)이 직관적 성향과 사고형 보다 많았고 판단형(50.7%)이 인지형 보다 많았다. 학업성취도는 여학생이 남학생 보다 높았고(t=3.277, p<.001), 내향적 성향이 외향적 성향 보다 높았다(t=3.541, p<.001). 성격유형별 학습스타일의 차이는 판단형이 다른 성격 유형간에 통계적으로 유의미한 차이를 보였다(${\chi}^2=18.409$, p<.001). 성별과 TF지표(r=.209, p<.05), 성별과 학업성취도(r=.265, p<.01), JP지표와 학습스타일(r=.262, p<.01), EI지표와 학업성취도(r=.285, p<.01) 사이에 유의한 양의 상관관계가 나타났다. 본 연구를 통해 확인된 간호학과 신입생의 성격유형, 학습스타일, 학업성취도 결과를 바탕으로 개인에게 적합한 교수-학습법의 개발 및 활용이 필요할 것이다.

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.
