As spent sulfidic caustic (SSC) from petroleum plants contains a high concentration of alkalinity and sulfur compounds, SSC can be applied in sewage treatment system as an electron donor for autotrophic denitrification. In our previous study, the reuse of SSC in the biological nitrogen process was successful, and some neutralization may be required for stable treatment performance. In this study, the pH of SSC was neutralized to 12.0 from 13.3, and the modified Ludzack-Ettinger process was conducted for 90 days with the municipal wastewater. Some toxic effects of SSC on microorganisms were tested via a specific oxygen uptake rate (SOUR) assay. According to the SOUR assay, as compared with no SSC injection condition, SOUR was reduced by approximately 5.4% when 4 mL SSC/L was injected and the effective concentration of a toxicant causing 50% inhibition of the microorganism’s activity (EC50) was 22.6 mL/L. During the days of operation, the COD removal and nitrification efficiency were over 53.0 and 98.2%, respectively. The TN removal efficiency was 56.6% and the nitrogen removal rate (NRR) was 0.15 kg/m³·d when the hydraulic retention time (HRT) in the anoxic tank was 3 h. The ratio of nitrifying bacteria was unaffected by the HRT, and Nitrobacter spp. and Nitrospira genus existed at similar ratios. The ratio of T. denitrificans increased after the injection of SSC and was approximately 6.5%.
Relationship between serum sodium level and coronary artery abnormality in Kawasaki disease

Purpose: Kawasaki disease (KD) is an immune-related multisystemic vasculitis that occurs in children, especially ensuing from a coronary artery abnormality. Sodium level is known to be related to vascular injury, which could affect the progress of KD. The purpose of this study was to determine the serum sodium levels that could predict the occurrence of cardiac and coronary artery events in KD. Methods: We conducted a retrospective review of medical records for 104 patients with KD from January 2015 to December 2015. Patients with serum Na levels of <135 mEq/L at the time of initial diagnosis were assigned to the hyponatremia group. Laboratory findings and echocardiographic data were analyzed for various aspects. Results: Among the 104 patients with KD, 91 were included in the study, of whom 48 (52.7%) had hyponatremia. The degree of fever, white blood cell count, percentage of neutrophils, percentage of lymphocytes, total bilirubin level, brain natriuretic peptide level, erythrocyte sedimentation rate, and C-reactive protein level were higher in the patients with hyponatremia. They also demonstrated a trend of larger coronary artery diameters based on Z scores. Conclusion: The severity of vascular inflammation in acute KD with hyponatremia might worsen the prognosis of coronary vasculature. Although no statistically significant correlation was found between the initial serum sodium levels and coronary arteriopathy in the patients with KD in this study, a long-term follow-up study with a larger number of enrolled patients should be designed in the future to elucidate the relationship between serum sodium level and coronary arteriopathy in patients with KD.
미술활동을 적용한 진로집단상담이 중학생의 자아정체감과 진로결정효능감에 미치는 효과

The purpose of the study was to investigate the effects of career group counseling by art activity on ego-identity and career decision-making efficacy of middle school students. The hypotheses of the study were first, an experimental group that was treated to career group counseling by art activity would have a higher ego-identity level than that of the control group. Second, the experimental group would have a higher career decision-making self-efficacy level than that of the control group. The subjects in K middle school, K city, Korea were assigned to 15 subjects in the experimental group and 15 subjects in the control group. The results showed that there were statistically significant differences in the six all sub-areas of ego-identity, namely subjectivity, self-acceptance, the future confidence, goal directness, leadership, and friendliness between the experimental and control groups. It meant that the career group counseling by art activity revealed positive effects on middle school students' ego-identity. It also indicated that there were statistically significant differences in the five all sub-areas of career decision-making efficacy, namely collecting information of occupation, setting the goals, planning, solving the problem and self evaluation between the two groups. It also meant that the career group counseling had positive effects on middle school students' career decision-making efficacy. 본 연구는 미술활동을 적용한 진로집단상담이 중학생의 자아정체감과 진로결정효능감에 미치는 효과를 알아보는데 목적이 있었다. 연구대상은 K시에 소재한 K중학교 2학년 학생들로서 본 프로그램의 내용과 목적을 이해하고 참여에 동의한 30명을 실험집단과 통제집단에 각각 15명씩 무선 배정하였다. 연구결과는 첫째, 미술활동을 적용한 진로집단상담을 실시한 집단은 통제집단에 비해 자아정체감의 하위영역인 주체성, 자기수용성, 미래 확신성, 목표지향성, 주도성 및 친밀성에서 유의미한 차이가 나타났다. 이는 미술활동을 적용한 진로집단상담이 중학생의 자아정체감에 긍정적인 영향을 미치고 있음을 보여주었다. 둘째, 미술활동을 적용한 진로집단상담을 실시한 집단은 통제집단에 비해 진로결정효능감의 하위 영역인 직업정보수집, 목표설정, 계획수립, 문제해결 및 자기평가에서 유의한 차이가 나타났다. 이는 미술활동을 적용한 진로집단상담이 중학생의 진로결정효능감에 긍정적인 영향을 미치고 있음을 나타내었다.
