This study will examine educational satisfaction on Estheticians who completed hygiene education, conduct survey on demands for educational programs which are required, and provide basic data for effective operation and qualitative improvement of skin beauty care hygiene education. Based on the above results, technique education by applying the recent trend in occupational intelligence should be performed as a way for improving satisfaction of hygiene education for learners. In particular, education should be prepared to increase the association with practical job in the general education.

본 연구의 목적은 코로나19 대응 차원에서 시작된 유아 대상 원격교육에 대한 유치원 교사의 인식을탐색하는 것에 있다. 이를 위해 유치원에서 원격교육을 실시한 경험이 있는 교사 9명을 편의표집하여 반구조화 면담을 실시하였다. 연구결과 유아 대상 원격교육에 대한 유치원 교사의 인식은 ‘유아 대상 원격교육의현주소’, ‘유아 대상 원격교육에 대한 딜레마’, ‘유아 대상 원격교육을 위한 제안’으로 범주화되었다. 유아대상 원격교육의 현주소는 준비없이 갑자기 시작된 원격교육, 교육의 주체에 대한 혼란, 차용해서 나열하는교육과정 운영으로 나타났다. 유아 대상 원격교육의 딜레마는 원격교육의 부작용, 피할 수 없는 원격교육의시대, 원격교육의 현실과 교육신념간의 간극, 가정의 조력여하에 따른 차이로 나타났다. 마지막으로 원격교육체제 마련, 양질의 콘텐츠 개발, 교수자의 역량 강화를 위한 교육 지원, 부모의 원격교육 조력 강화를 위한교육 지원을 제안하는 것으로 나타났다. 이러한 연구결과를 토대로 유아 대상 원격교육이 원활하게 이루어질수 있는 기반을 마련하고 내실화를 도모하는 방안에 대해 논의하였다. The purpose of this study is to explore the perceptions of kindergarten teachers on distance education for young children, which began in response to COVID-19. Nine teachers with experience in distance education in kindergarten participated in this study and semi-structured interviews were conducted with them. As a result of the study, kindergarten teachers’ perceptions of distance education were categorized into three themes of ‘the current status of distance education’, ‘deliberations over distance education’, and ‘suggestions for distance education’. Teachers responded that the current situation with distance education began suddenly without preparation, which caused the state of education currently is in turmoil. They also reported that such situations forced teachers to manage the curriculum manually without any creativity. Teachers’ deliberations on distance education mostly revolve around concerns on the side effects of distance education, acceptance of the era of inevitable distance education, recognition of the gap between the reality of distance education and their educational beliefs, and the necessity of assistance from one’s family. Teachers suggested the provision of a distance education system, development of high-quality contents, and education support to strengthen the competence of instructors to be considered for distance education. Ways to manage quality programs and insure substantiality for young children’s distance education were discussed.

Background: Contralateral pulmonary resection after pneumonectomy presents considerable challenges, and few reports in the literature have described this procedure. Methods: We retrospectively reviewed the medical records of all patients who underwent contralateral lung resection following pneumonectomy for any reason at our institution between November 1994 and December 2020. Results: Thirteen patients (9 men and 4 women) were included in this study. The median age was 57 years (range, 35–77 years), and the median preoperative forced expiratory volume in 1 second was 1.64 L (range, 1.17–2.12 L). Contralateral pulmonary resection was performed at a median interval of 44 months after pneumonectomy (range, 6–564 months). Surgical procedures varied among the patients: 10 underwent single wedge resection, 2 were treated with double wedge resection, and 1 underwent lobectomy. Diagnoses at the time of contralateral lung resection included lung cancer in 7 patients, lung metastasis from other cancers in 3 patients, and tuberculosis in 3 patients. Complications were observed in 4 patients (36%), including acute kidney injury, pneumothorax following chest tube removal, pneumonia, and prolonged air leak. No cases of operative mortality were noted. Conclusion: In carefully selected patients, contralateral pulmonary resection after pneumonectomy can be accomplished with acceptable operative morbidity and mortality.

Suppressors of cytokine signaling (SOCS) exhibit diverse antiinflammatory effects. Since ROS acts as a critical mediator of inflammation, we have investigated the anti-inflammatory mechanisms of SOCS via ROS regulation in monocytic/macrophagic cells. Using PMA-differentiated monocytic cell lines and primary BMDMs transduced with SOCS1 or shSOCS1, the LPS/TLR4- induced inflammatory signaling was investigated by analyzing the levels of intracellular ROS, antioxidant factors, inflammasome activation, and pro-inflammatory cytokines. The levels of LPS-induced ROS and the production of pro-inflammatory cytokines were notably down-regulated by SOCS1 and up-regulated by shSOCS1 in an NAC-sensitive manner. SOCS1 up-regulated an ROS-scavenging protein, thioredoxin, via enhanced expression and binding of NRF-2 to the thioredoxin promoter. SOCS3 exhibited similar effects on NRF-2/thioredoxin induction, and ROS downregulation, resulting in the suppression of inflammatory cytokines. Notably thioredoxin ablation promoted NLRP3 inflammasome activation and restored the SOCS1-mediated inhibition of ROS and cytokine synthesis induced by LPS. The results demonstrate that the anti-inflammatory mechanisms of SOCS1 and SOCS3 in macrophages are mediated via NRF-2-mediated thioredoxin upregulation resulting in the downregulation of ROS signal. Thus, our study supports the anti-oxidant role of SOCS1 and SOCS3 in the exquisite regulation of macrophage activation under oxidative stress. [BMB Reports 2020; 53(12): 640-645]

Lipoxygenase (LOX) is the key enzyme involved in the regio- and stereoselective synthesis of oxylipins. The oxylipins, a group of structurally diverse and biologically active oxygenated molecules, are essential signaling messengers involved in human physiological responses. Herein, we discovered bacterial LOX from Enhygromyxa salina (Es-LOX) with unique regiospecificity. C18-polyunsaturated fatty acids (PUFAs) were converted to 9S-form products, indicating that the regiospecificity of Es-LOX differs from that of other bacterial LOXs. The catalytic efficiency (kcat/KM) was the highest for Linoleic acid. The kcat/KM of linoleic acid was 1.51 s<SUP>-1</SUP> μM<SUP>-1</SUP>, which was 2.4-fold higher than the second favored substrate ɣ-linolenic acid. The Es-LOX was engineered to improve the solubility by fusion with maltose binding protein (MBP), which led to the synthesis of target products with high-conversion. For instance, 100 mM linoleic acid was transformed into 83 mM 9Shydroxy-(10E,12Z)-octadecadienoic acid by the recombinant Escherichia coli BL21(DE3) pb4-Es-LOX and tris(2-carboxyethyl)-phosphine (TCEP). In addition, we produced the secondary fatty alcohol [i.e., 8S-hydroxy-(9E,11Z)-heptadecadiene] from the hydroxy fatty acid [i.e., 9S-hydroxy-(10E,12Z)-octadecadienoic acid] by using a single whole-cell biocatalyst, coexpressing Es-LOX and photoactivated decarboxylase from Chlorella variabilis. This study will contribute to the development of biotransformation processes for the synthesis of diverse fatty acid derivatives.

본 연구에서는 4년근 인삼의 활용도를 높이기 위하여 효소적 가수분해 조건에 따른 품질 특성을 조사하였다. 인삼은 증숙 후 분쇄하여 가수분해 효소제 A, B, C 및 D 4종에 처리에 따른 품질특성을 조사한 결과 pH 5.5~5.6, 당도 4.0~4.33으로 큰 차이가 없었다. 조사포닌 함량은 D 효소제에서 가장 높았으며, B, C 및 A 순으로 나타났다. D 효소제의 농도 0.3%(w/w)까지 조사포닌, 환원당 및 총당 함량이 증가하였으며 이후에는 농도에 따른 차이는 없었다. 가수분해시간이 경과함에 따라 유효성분이 증가하였으나 3시간 이후 큰 변화는 없었으며, 60℃로 처리하였을 때 조사포닌 함량이 높게 나타났다. 이상의 실험결과 D 효소제, 효소제 농도 0.3% (w/w)로 60℃에서 3시간의 조건이 가장 적합한 나타났으며 이때 환원당, 총당 및 조사포닌 함량은 각각 18.11, 36.21 및 4.23 ㎎/g으로 확인되었다. 따라서 효소적 가수분해 방법은 4년근 인삼의 유효성분 증가에 효과적으로 다양한 활용 방법이 기대되었다. This study investigated quality characteristics of 4 year-old ginseng by enzymatic hydrolysis conditions to increase utilization. Ginseng was ground after steaming and was each treated with hydrolase A, B, C and D. When quality characteristics by the enzymes were examined, no significant difference was observed with pH of 5.5~5.6 and the sugar content of 4.0~4.33. The crude saponin content was the highest in ginseng treated with D, followed by B, C and A. The crude saponin, the reducing sugar and the total sugar contents increased until 0.3% (w/w) concentration in enzyme D with no significant difference by its concentration. Although active ingredients increased with time passage of hydrolysis, no significant change was found after three hours and the crude saponin content was the highest when ginseng was treated at 60℃. From these results, optimum conditions for 4 year-old ginseng were 60℃ for 3 hours with 0.3% (w/w) enzyme D, and under these conditions the reducing sugar, the total sugar and the crude saponin contents recorded 18.11, 36.21 and 4.23 ㎎/g, respectively. Therefore, enzymatic hydrolysis was found to be effective in increasing active ingredients of 4 year-old ginseng with various usages expected.
