Purpose: The purpose of this study was to identify sleep patterns, alertness, and fatigue of shift nurses according to circadian types. Methods: The researchers' enrolled 17 nurses doing shift work in a tertiary hospital. To evaluate circadian types, a morningness-eveningness questionnaire (MEQ) was administered. Sleep patterns were examined using an actigraph for 14 days. To assess alertness and fatigue, Visual Analogue Scale (VAS) was used. The data were analyzed using ANOVA and Kruskal-Wallis test with a SPSS 21.0 program. Results: The researchers found that 17.6% of participants reported morning type, 47.1% neither type, and 35.3% evening type. Mean total sleep time (TST) was 6.8 h, mean sleep efficacy was 82%, level of alertness was 6.54, and level of fatigue was 5.49, regardless of the type of shift work. Evening type nurses had higher variation in TST and alertness, according to the shift patterns than other circadian type nurses. Evening type nurses also had higher fatigue levels than other circadian type nurses. Conclusion: Sleep, alertness, and fatigue were related with circadian types. These results suggest that circadian rhythm management in shift work nurses, particularly in evening type nurses is urgently needed to improve sleep patterns, alertness, and to decrease the level of fatigue.

백지현(Ji-Hyun Baek) 한국산학기술학회 2020 한국산학기술학회논문지 Vol.21 No.8

방위산업은 국가 안보 유지를 위한 기간산업이자 첨단기술이 집약된 미래지향 산업으로써, 방위산업의 연구개발은 무척 중요하다. 우리 정부의 자주국방에 기반을 둔 과감한 정책으로, 국내 방위산업은 양적, 질적으로 많은 성장을 이루었다. 하지만 전문화 및 계열화 제도의 폐지에 따른 경쟁체제의 도입은 국내 방위산업체의 효율성 및 생산성 향상의 필요성이 대두되는 계기가 되었다. 본 연구에서는 DEA와 Super-SBM을 이용하여 국내 방위산업체의 연구개발 효율성을 측정하고자 한다. 이를 위해 한국방위산업진흥회의 ‘2019 방산업체 경영분석’ 데이터를 활용하였으며, 국내 방위산업체의 연구원수 및 투자액을 투입변수로, 매출액을 산출변수로 설정하여 분석을 수행하였다. 방위산업체의 효율성을 분석하기 위해 규모수익불변(CRS)을 가정하는 CCR 모형과 규모수익가변(VRS)을 가정한 BCC 모형을 활용하였으며, 효율적인 업체들 간의 순위를 확인하기 위해 Super-SBM 모형을 사용하여 초효율성을 도출하였으며, 국내 방위산업체는 대체로 비효율적인 모습을 보였다. 본 연구를 통한 국내 방위산업체의 연구개발 효율성을 파악하여 향후 국내 방위산업체의 육성 정책 수립에 도움이 되기를 기대한다. The defense industry is a future-oriented industry, in which high-tech technologies are concentrated. In addition, it is a key industry for maintaining national security, and the R&D of the defense industry is very important. With the introduction of a competitive system by defense industry companies, the necessity of improving the efficiency and productivity of defense industry companies is emerging. In this study, the efficiency of the defense industry was measured using the CCR and BCC model. In addition, super efficiency was derived using the Super-SBM model. For this study, the 2019 defense industry management analysis data of the Korea Defense Industry Association (KDIA) was used, and the analysis was performed by setting the number of researchers and investments of domestic defense industry companies as the input variables and sales as the output variables. Through this study, it is expected that the defense industry"s R&D efficiency will be grasped, which will help establish a policy for fostering the defense industry in the future.

Objectives: The purpose of the study was to investigate the content analysis of daily tooth cleaning service records by caregivers in a long-term care facility. Methods: The data were analyzed by qualitative research based on content analysis of the daily records of the processes and results of daily tooth cleaning service. Twenty caregivers provided tooth, gum and denture cleaning service after breakfast, lunch, and dinner to 48 elderly residents. The study lasted about two weeks(from August 4 to August 20, 2014). The researcher reconstructed the language by repeatedly reviewing the caregivers statements in the records. The content categories were derived from the records through a reiterative manual comparative analysis. Using constant comparison method, reconstructed meanings were incorporated into various meanings and reanalyzed by final categories called as analytic coding. In order to validate the reliability, 6 times of discussion made the common meanings through a master’s degree student and a dental hygiene professor. Results: The caregivers identified lack of understanding and ability to recognize the functional physical and mental changes in the elderly. The elderly had difficulty in recognizing silent communication and daily tooth cleaning. The caregivers were so strenuous in taking care of the daily tooth cleaning service for the elderly. At last, they gave up the daily tooth cleaning service and took on it to the guardians. They found that there was no social supporting network for oral health of the elderly residents. Conclusions: Caregivers had insufficient understanding of the functional physical and mental changes in the elderly residents, and they had difficulty providing daily tooth cleaning service to the elderly due to poor skill and abilities.

본 저자들은 손가락의 골절과 감염이 동반된 SAPHO 증후군에서 경구 bisphosphonate로 성공적으로 치료하였기에 이를 보고하는 바이다. SAPHO syndrome, characterized by synovitis, acne, pustulosis, hyperostosis, and osteitis is rare compared to other spondyloarthropathies. It is also difficult to diagnose, and treatment methods have not yet been fully identified. Approximately 72% of patients are diagnosed with at least one other disease before a final diagnosis of SAPHO syndrome. In addition, SAPHO syndrome is subject to a delayed diagnosis period of 4.5 to 9.1 years. Medications such as non-steroidal anti-inflammatory drugs, disease-modifying anti-rheumatic drugs, and tumor necrosis factor inhibitors are used in treatment of SAPHO syndrome. Bisphosphonate is also used for refractory SAPHO syndrome; however, most reports on this relate to intravenous injection of medication. The authors experienced and subsequently reported on a case involving a patient with SAPHO syndrome accompanied by fracture and infection of the left second finger who was treated with the oral biphosphonate, alendronate.

Objectives : Recurrence of mood episodes associated with a specific season has been described in various mood disorders. Seasonal change in mood and behavior as a lifetime trait is also observed in healthy individuals. This study aimed at comparing the lifetime trait of seasonal variations of mood and behavior between bipolar disorder patients and controls as well as investigating associated factors of seasonality. Methods : Subjects were ninety-four clinically stable patients with bipolar disorder and 188 age- and sex-matched healthy controls. Seasonality of mood and behavior was assessed retrospectively on lifetime basis using Seasonal Pattern Assessment Questionnaire(SPAQ). Results : The patient group showed a higher median global seasonality score(GSS) of SPAQ and a higher rate of seasonal affective disorder(SAD) compared to the control group(p < 0.0001). For subjects showing prominent seasonality, the seasonal symptom profile and seasonal pattern was similar in both patient and control groups. In addition to the diagnosis, female gender was shown to be a predictor of seasonality in the multiple linear regression analysis(p = 0.045). Conclusion : This study suggests that lifetime trait of seasonality may be related to the susceptibility of bipolar disorder.

Objectives Second-generation antipsychotics (SGAs) are frequently used in the treatment of bipolar disorder. However, there is still no consensus on their risk of tardive movement syndromes especially for first-generation antipsychotics (FGAs)-naive patients. This study aimed to investigate the prevalence and associated factors of SGAs-related tardive dyskinesia and tardive dystonia in patients with bipolar disorder, in a naturalistic out-patient clinical setting. Methods The authors assessed 78 non-elderly patients with bipolar (n = 71) or schizoaffective disorder (n = 7) who received SGAs with a combined use of mood stabilizers for more than three months without previous exposure to FGAs. Multiple direct assessments were performed and hospital records longer than one recent year describing any observed tardive movement symptoms were also reviewed. Results The prevalence rates of tardive dyskinesia and tardive dystonia were 7.7% and 6.4%, respectively. These patients were being treated with ziprasidone, risperidone, olanzapine, quetiapine, or paliperidone at the time of the onset of the movement symptoms. Tardive dyskinesia was mostly observed in the orolingual area, and tardive dystonia was most frequently detected in oromandibular area. A past history of acute dystonia was significantly associated with presence of both tardive movement syndromes. Conclusions Our findings suggest that SGAs-related tardive movement syndromes occur in a substantial portion of bipolar disorder patients. Acute dystonia, a reported risk factor of tardive movement syndromes in the era of FGAs is confirmed as a risk factor of both tardive dyskinesia and tardive dystonia that were induced-by SGAs.

Staphylococcus lugdunensis is a member of coagulase-negative staphylococci (CoNS), an uncommon microbial culture isolate with virulent potency. Although CoNS are common skin commensals, and often regarded as contaminants or colonizers when isolated from clinical specimen cultures, the clinical course and microbiological characteristics of Staphylococcus lugdunensis may resemble those of Staphylococcus aureus rather than other CoNS. Invasive infectious diseases such as infective endocarditis, peritonitis, skin and soft tissue infection, vascular prosthetic infection, septicemia, and osteomyelitis have been found to be associated with Staphylococcus lugdunensis. Here we report the first case of psoas abscess caused by methicillin-sensitive Staphylococcus lugdunensis in Korea.

Objectives : The purpose of the study is to investigate the xerostomia in the chronic severe psychiatric patients in Korea because there were few reports on xerostomia in the psychiatric patients. Methods : The subjects were 61 psychiatric patients in the mental hospital by convenience cluster sampling. A self-reported symptom questionnaire was filled out by the three researchers on the basis of medical records by the informed consent. The stimulated salivary flow rate of the patients was measured by saliva sampling. Results : The subjects consisted of 45.9% of male and 54.1% of female. High school graduation accounted for 40.0% and 20.0% did not attend the school. The majority of the patients were medicaid recipients. Schizophrenia accounted for 86.9% and most patients were long term care recipients. A total of 68.9% of the patients suffered from salivary dysfunction. The medication in schizophrenia seemed to decrease the stimulated salivary flow rate and made the patients difficult in chewing and swallowing due to xerostomia and low saliva secretion(p<0.05). Conclusions : Medication in schizophrenic patients caused the salivary dysfunction. So the collaboration between the psychiatry doctors and dental hygienists is very important to improve the salivary secretion in the schizophrenic patients. The continuous and long term care of the xerostomia will help the patients maintain the good oral hygiene.

  Banja is the unique metal product of Korea produced by hundreds of quenching and beating an alloy of copper and tin in a ratio of 78 to 22. It has a secret that has not been solved in a scientific way. Recently, Banja became popular again as it is known of less toxicity and sterilization. Based on the trend, we examined antimicrobial activity of copper and tin alloy against E. coli to use this alloy benefit to the environmental health area. Despite of different strengths, copper and tin alloy had an effect to restrain proliferation of E. coli in the experiment. Thus, we tried to proved significance of the antimicrobial activity through statistical treatment. It is verified that about 50% of the number of colonies are reduced in 1/10 diluted solution and 30% in 1/100 diluted solution where copper and tin alloy is treated. However, the statistical significance could not be proved due to big standard deviation despite of big average reduction. It is likely to have a significant result if conducting an experiment with well-controlled strain and more samples. Banja is known of various effects such as not only the antifungal activity as in the experiment but also maintenance of the electrolytic reduction number and prevention of protein destruction and so on. Thus it is important to develop the unique property of copper and tin alloy that contains the wisdom of our ancestors to be beneficial to the environmental health area. This study thus contributes to providing fundamental data to the field.
