This study is an attempted content analysis study to analyze recent studies on clinical practice of nursing college students to identify problems with clinical practice and provide evidence for desirable clinical practice. For data collection, a total of 14 papers published in academic journals between 2017 and 2021 were selected. The analysis method was performed according to the systematic review reporting guidelines presented by Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) group. As a result of the analysis, two themes, Four sub-themes, and seventeen concepts were derived, and the clinical practice study of nursing college students showed the necessity of standardized clinical practice protocol regulations for nursing college students and respect for patient human rights. Based on the above research results, it is proposed to prepare a nursing and clinical practice protocol that can clearly present the role of nursing college students during clinical practice.

One of the current treatment methods for chronic osteomyelitis is removal of the infected and necrotic tissue to reduce the bacterial concentration as much as possible. This is performed concomitantly with antibiotic therapy. Chronic osteomyelitis(C.O.) implies chronic ischemia of the diseased bone. Thus, the treatment for C.O. requires high systemic level of antibiotics. In some cases, however, inherent undesirable adverse effects(for example, nephrotoxicity, ototoxicity, and others) may render this course of treatment difficult. Knowing that residual monomers are released from hardened bone cement, installation of antibiotic-impregnated PMMA(polymethyl-methacrylate) beads in situ have been one of treatment methods of C.O. When introduced into the wound, they established an exceedingly high level of local antibiotics for prolonged period without high systemic level of antibiotics. We experienced favorable results with vancomycin-impregnated PMMA beads for the treatment of C.O. of the mandible. So, we report it with literature reviews.

Objectives : This study aims to evaluate domestic/foreign clinical studies related to the traction therapy and analyse points to consider about cervical/lumbar traction therapy. Methods : Seven databases were searched for related articles about cervical/lumbar traction therapy from 1950 to 2014. Fourteen clinical studies and several systemic reviews were included among 144 studies searched. Out of fourteen clinical studies, four were case series and ten were controlled trials. Results : Most of included studies reported favorable effects of traction group compared to baseline of controlled group. The various mechanical factors most relevant to traction are 1) angle of pull and direction, 2) traction force, 3) duration of traction and frequency of treatment. Conclusions : We found various mistake in the applications of statistical methodologies of traction therapy targeting patients of cervical, lumbar vertebral disease. It is necessary for more randomized controlled trials to evaluate effect of cervical/lumbar traction therapy targeting patients of cervical, lumbar vertebral disease.

Objective: This paper discusses the recent challenges to human factors engineering due to the safety culture. Background: As incidents occurring in specific fields such as logistics, plant, energy and medical sectors in Korea, as well as in the public sectors including railway, road, aviation and shipping, are recently raised as social issues from the disaster dimension, those incidents are dealt with as man-made disasters in many cases. The trend regarding all accidents as man-made disasters has been expanded in the active perspective that the controllability of all incidents should be ensured in technology development, due to change from a fatal point of view regarding disasters as random occurrence of uncertainties in the past. Method: Man-made disasters are concluded as human errors, and safety culture stands out as a cause of human errors or a new cause item recently. Because safety culture, however, is a very comprehensive term, of which true nature is obscure, although many definitions of safety culture have been presented, the safety culture may make avoid the true nature and responsibility of an incident, or make the main player and subject obscure. Raising safety culture as a cause without presenting a specific countermeasure will be just a wisdom of hindsight. Results and Conclusion: This study reviews the fundamental discussions on "Is safety culture a task of human factors engineering?" and the existing approach carried out from various perspectives in order to seek an effective approach on the new task of safety culture in the human factors engineering field. This study discusses an engineering approach to meet a precondition that safety culture is not just an added factor through a review of the approaches in the proactive fields such as nuclear power and aviation, and the traditional approaches of human factors engineering. Application: This study especially defines the perspective of socio-technological system that has expanded the existing man-machine system, and discusses a systemic approach embracing various interactions, and several overriding tasks.

This paper aims to propose the strategy making in social enterprise for ensuring organizational sustainability and governance of social enterprise from systems thinking's perspective. Based on previous reviews on organizational sustainability and theories of governance currently advocated in the social enterprise literature, we use 'Holon Dynamics' approach, which is a synthesis of System Dynamics and Soft Systems Methodology (SSM), offers the problem-solving method for dealing with social contexts and "ill-defined" situations. To do so, a researcher carried out the interpretive action research using 'Holon Dynamics' approach from September, 2009 to August, 2010. The outcomes of research are summarized as follows. Firstly, systems methodologies are useful to offer a strategic choice that makes to achieve an organizational sustainability in the case of Korean social enterprise; 'the Rediscovery of Korea'. Secondly, systems thinking offers an alternative concept of system, which is known as an 'appreciative system' that is evolved from the mental constructs amongst participants in given situations. Lastly, the paper delineates the usefulness of systems thinking and the process of inquiry, which deal with social contexts (including cultural and political factors), are contributed to making the necessary conditions for organizational legitimacy and the appropriate strategic choice for social enterprise within combined functioning of the two roles of social and commercial activities from systemic perspectives.

Natural Killer/T-cell(NK/TC) lymphoma is a rare disease of oral and maxillofacial region with an aggressive clinical course, showed unusual clinical manifestations. Prognosis is generally poor and the disease is invariably fatal after systemic dissemination. A case of nasal NK/TC non-Hodgkin's lymphoma in the left maxilla that showed unusual clinical manifestations and a fulminant course of disease, are described with literature reviews. A 81-year-old female patient presented with rapidly growing ulceration and general malaise after extraction of right upper second premolar NK/TC lymphoma was subsequently detected by biopsy. rapid and wide invasion from maxilla to mandible developed within 10 days and multiple metastasis to whole body was after a few weeks. Although the time relationship is not clear, local invasion and multiple metastasis could be dissemination from localized disease of NK/TC. As seen in my case, the course can be excessively aggressive and fulminant even though it first appeared as a localized ulceractive lesion. She is expired 2 months after biopsy. Positivity of immunohistochemical stain (CD56, LCA, UCHL-1, CD3), which is a specific characteristic of NK/TC, may serve as a factor showing a poor prognosis of a malignant lymphoma

Objectives After the initial investigations by the Korea Centers for Disease Control in 2011, over 1000 suspicious cases of humidifier disinfectant (HD) victims were subsequently reported by 2015, and numbers are still increasing dramatically in 2016 in the midst of the prosecutors' office investigation. This study attempts to summarize the current understandings of the related health effects of HD based upon a systemic review of published epidemiologic studies and toxicology investigations. Methods Published studies of HDs were searched through PubMed and TOXLINE under the search words 'humidifier disinfectant,' and related reports were identified from the references and published report list of regulatory agencies including the Korean National Institute of Environmental Research, US Environmental Protection Agency, and EU European Chemicals Agency. Results Case reports and epidemiologic studies have reported the clinical features of severe forms of HD lung damage, together with epidemiologic findings of seasonal occurrence and demographic variations, including the heightened susceptibility of young children. Toxicological studies have reported inhalation toxicities together with positive findings of in vitro genotoxicity studies. Conclusions This study examined unsolved issues based on cases of upper respiratory diseases and diseases of other organs, including cancers, among suspected victims of HDs. These issues should be clarified in future research for the management and prevention of health effects from HDs and chemicals of other related household products.

Pancreatic neuroendocrine tumors (pNETs) are rare and heterogenous tumors and surgery to remove the primary tumor is the mainstay of treatment for resectable disease. However, curative surgery is often not feasible, because half of patients with pNET have metastases at the time of diagnosis. Palliative dubulking surgery and liver-directed therapies are appropriate options for these patients. Streptozocin-based regimens are standard, although temozolamide-based treatments are rapidly gaining wide clinical application. Somatostatin analogs are mainly indicated in hormonally active tumors to ameliorate symptoms. In addition, anti-tumoral activity has been proven in well-differentiated NETs. Recently, there has been tremendous progress in the molecular biology of pNETs; thereby, the efficacy of sunitinib and everolimus in the treatment of patients with metastatic pNETs has been proven by large placebo-controlled phase III trials. Currently, there are no definitively proven predictive biomarkers to evaluate response to medical therapies in patients with pNET. Therefore, further studies are needed to individualize and optimize their management. This article reviews systemic chemotherapy, targeted therapies, and anti-secretory treatments for the management of patients with unresectable or metastatic pNETs, summarized in the light of recent advances.

Purpose: The aim of this study was to conduct a systematic review and to describe the characteristics of child abuse screening instruments. Methods: Articles regarding the development of a child abuse screening instrument were investigated using the systematic review method. A literature search using the keywords "child and abuse or maltreatment and instrument or screening tool" in English, and "child," "abuse," and "instrument" in Korean, was conducted of material published in PubMed, PsycINFO, CINAHL, SCOPUS, ERIC, and RISS. Database and bibliographic searches, and quality appraisal using the Quality Assessment of Diagnostic Accuracy Studies tool that included systemic reviews, yielded 17 records. Results: Key elementary child abuse screening instruments were developed for physical, psychiatric, affective and sexual and child neglect assessment. The instruments' target populations were children at home and in institutions. The reviewed instruments had the advantage of diagnosing past, concurrent, and indirectly, potential child abuse. Conclusion: The results of this study demonstrate that child abuse screening instruments are available for screening and for assessment of abused children in various circumstances. This review of child abuse screening instruments offers evidence for the acceptable use of optimal psychometric tools for child abuse assessment and provides guidelines for child health nursing practice.

Resistance to chemotherapy treatment, which may lead to limited efficacy of systemic therapy in breast cancer patients, is multifactorial. Among the mechanisms of resistance to chemotherapy treatment, there are those closely related to estrogen receptor ${\alpha}$, P-glycoprotein, multidrug resistance-related protein, glutathione S-transferase pi and topoisomerase-II. $ER{\alpha}$ is ligand-activated transcription factor that regulates gene expression and plays a critical role in endocrine signaling. In previous preclinical and clinical studies, positive $ER{\alpha}$ expression in breast cancer cells was correlated with decreased sensitivity to chemotherapy. This article reviews current knowledge on the predictive value of $ER{\alpha}$ with regard to response to chemotherapy. Better understanding of its role may facilitate patient selection of therapeutic regimens and lead to optimal clinical outcomes.
