Purpose: Personal protective equipment (PPE) is critical for protecting healthcare workers from COVID-19 outbreaks. Therefore, this study examined the effects of a nursing simulation education program on PPE use for COVID-19 among nursing students. Methods: We employed a non-equivalent control group post-test design. The experimental group (n=38) engaged in a nursing simulation education program on PPE use. The control group (n=36) received PPE and the opportunity to participate in the same program after the intervention. Further, data were analyzed using descriptive statistics and independent t-test. Results: The experimental group showed significant differences in attitude toward PPE (t=3.21, p=.002) and efficacy of PPE use (t=9.92, p<.001), but not in the intention to care for patients with COVID-19 (t=0.95, p=.343). Conclusion: Nursing simulation education for PPE significantly improved attitude and increased self-efficacy toward PPE among nursing students. However, the intention to care for COVID-19 patients was not changed. Thus, it is necessary to find a way to improve the nursing intention toward COVID-19 patients.

More than 90% of students were satisfied with the education program and the simulation education effectiveness was 2.54 on a 3-point Likert scale. Conclusion: The S-PBL program could be useful in clinical nursing education for nursing students seeking to become clinical nurses. It is necessary to develop various S-PBL programs and apply them to the curriculum.

This paper provided the information related to the removal of 2,4,6-tribromophenol using in-situ and stable liquid ferrates(VI). This research’s goal was to observe the differences of oxidation power between in-situ liquid ferrate(VI) and stable liquid ferrate(VI). The in-situ liquid ferrate(VI) (FeO4 2-) has been successfully produced with the concentration 42,000 ppm (Fe) after 11 minutes of reaction time. The stable liquid ferrate(VI) was also successfully produced following the modification method by Sharma with the produced concentrations 7,000 ppm. The stable liquid ferrate(VI) was stable for 44 days and slightly decreased afterwards. This research has been carried out using 2,4,6-tribromophenol as the representative compound. Both of ferrates(VI) have the highest oxidation capability at the neutral condition. Furthermore, the stable liquid ferrate(VI) has higher oxidation power than the in-situ liquid ferrate(VI).

The stability of liquid ferrate(Ⅵ) produced by an innovative method was confirmed and the degradation characteristics of cyclic compounds(Benzene, Aniline, Toluene, 1,4-Dioxane) by liquid ferrate(Ⅵ) were investigated under the same reaction conditions. When it was compared with the ferrate manufactured by the wet oxidation method, the liquid ferrate was more stable. And the stability of liquid ferrate was tested at the storage temperature. As a result, only 17.7% of liquid ferrate(Ⅵ) has decomposed at the storage temperature(4˚C) for 28 days. Among the cyclic compounds, the aniline was rapidly degraded compare to other cyclic compounds, which seems to be due to the electron-donating ability of the substituent, -NH2 group. Especially, when 1,4-dioxane was compared with benzene, the decomposition rate of 1,4-dioxane was lower than that of benzene, suggesting that oxygen atoms hinder the electrophilic reaction. Among 4 cyclic compounds, it was observed that aniline has the highest rate constant than those of other cyclic compounds.

This study analyzed the correlation between Chl-a and water quality factors using characteristics of climate data, water quality factors, and various statistical analysis techniques during the summer season in the Nakdong River during the 2-year period. The purpose of this study is to provide the basic data for establishing water quality management policy in the Changnyeong-Haman weir section. From the end of July to the middle of August when algae mainly occur, both the years 2015 and 2016 are in the temperature range of 25 ~ 30 °C, and the total precipitation of 2015 is less than that of 2016 in this period. As a result of comparing the concentration of Chl-a, the average Chl-a concentration of 2015 was higher than that of 2016, which seems to be related to the total precipitation in the occurrence of algae. The results of the correlation analysis showed that the correlation with PO4-P was significant at most points. As a result of the factor analysis, the first principal factor group classified PO4-P, NH3-N, TP, pH, flow rate, TN and this section seems to be influenced by phosphorus and nitrogen and flow rate.

Bacillus thuringiensis subsp. kurstaki KB100 isolated from the domestic soil have the most effective activity against the beet armyworm, Spodoptera exigua larva. The tannic acid as protease inhibitor might be increased the efficacy of sublethal concentrations of B. thuringiensis. The tannic acid was identified as a protease inhibitor that could increased the efficacy of sublethal concentrations of B. thuringiensis. Mixture of B. thuringiensis and tannic acid was investigated the mortality of S. exigua larva in the laboratory and field. When B. thuringiensis treated to 2nd larva of S. exigua, mortality was shown 54.4%. However, mixtures of B. thuringiensis with 4 and 40 mM tannic acid were increased mortalities to 2nd larva of S. exigua as 64.0 and 95.5%, respectively. Also, synergy effect of mixture of B. thuringiensis and 40 mM tannic acid was increased the mortality of S. exigua 3rd larva to 93.3%, even though 60.0% mortality with only B. thuringiensis treatment. On the other hand, the mortality of mixture with B. thuringiensis and 80 mM tannic acid was 53.3% lower than B. thuringiensis single treatment. In the welsh onion field, the accumulated mortalities of 3 times replicated with mixture of B. thuringiensis and 40 mM tannic acid were 83.9, 89.4 and 66.8% compare with 61.8, 80.4 and 47.3% as only B. thuringiensis treatment, respectively.

토양에서 분리한 B.thuringensis 균주 들 중 Spodoptera litura에 활성이 높은 CAB133을 선발하였다. H serotype을 동정한 결과 혈청형이 3abc인 kurstaki로 동정되었다. 전형적인 이중 피라미드형의 결정성 내독소 단백질과 형태적인 유사성을 보였고, S. litura 유충에 대한 생물활성 결과 kurstak HD-1균주에 비해 높은 활성을 보였다. 혈청학적으로 동일한 균주일지라도 각각의 균주가 생산하는 결정성 독소단백질의 유전자가 다르기 때문에 해충의 살충성에는 차이가 나타나므로 분자생물학적인 특성을 알아보았다. 내독소 단백질 특성을 비교하기 위하여 SDS-PAGE를 수행한 결과, kurstak HD-1은 130kDa과 약 60kDa의 주요 단백질 밴드를 나타내었으나 CAB133균주는 130kDa의 주요 단백질 밴드만을 가지고 있었다. 균주의 전체 plasmid profile을 분석한 결과 kurstak HD-1균주는 7개, CAB133균주는 10개의 plasmid를 포함하고 있었으며 crystal을 형성하지 못하는 Cry-균주를 배양하여 확인한 결과 Cry+와 하나의 밴드가 없는 9개의 plasmid를 가지고 있음을 확인하였다. 균주의 crystal toxin을 확인하기 위해 usual primer로 PCR을 수행한 결과 kurstak HD-1은 cry1Aa,cry1Ab, cry1Ac, cry1I, cry2 gene을 CAB133은 cry1Aa, cry1Ab, cry1Ac, cry1C, cry1D, cry2 gene이 있음을 확인하였다.
