  • This paper proposes a multi-disciplinary approach for fashion criticism in museology through an analysis of the 2014 Charles James's retrospective. It includes the following elicitations. First, it explores a critical discussion of "dress museology" as well as "fashion museology" and the complexity of fashion in museums. Second, this paper reorganizes Fleming's (1974) artifact study and Crane and Bovone's (2006) critical theory for fashion criticism in museology by comparing "object-based" research with an "academic" approach. Third, it applies fashion criticism methodology as a case study to the aforementioned museum fashion exhibit, entitled . We can subsequently begin to reconsider concepts of art and fashion within present culture based on inclusive fashion criticism of aesthetic and cultural events.

  • This article aims to provide a systematic review of the exposure assessment methods used to assign wafer fabrication (fab) workers in epidemiologic cohort studies of mortality from all causes and various cancers. Epidemiologic and exposure-assessment studies of silicon wafer fab operations in the semiconductor industry were collected through an extensive literature review of articles reported until 2017. The studies found various outcomes possibly linked to fab operations, but a clear association with the chemicals in the process was not found, possibly because of exposure assessment methodology. No study used a tiered assessment approach to identify similar exposure groups that incorporated manufacturing era, facility, fab environment, operation, job and level of exposure to individual hazardous agents. Further epidemiologic studies of fab workers are warranted with more refined exposure assessment methods incorporating both operation and job title and hazardous agents to examine the associations with cancer risk or mortality.

  • Objectives: Obstructive sleep apnea (OSA) is common in people with epilepsy (PWE), and confers medical and seizure-related consequences when untreated. Positive airway pressure, the gold-standard for OSA management, is limited by tolerability. As serotonin is involved respiratory control and amelioration of seizure-induced respiratory events, this study aims to determine whether serotonin reuptake inhibitors (SRIs) may represent a potential therapeutic option. Methods: A retrospective study of 100 PWE and OSA ${\geq}18$ years of age was conducted. The primary outcome measure was OSA severity as function of SRI use, with rapid eye movement (REM)-related OSA as a secondary outcome. Results: Older age and depression were more common in those taking an SRI. There was no association between SRIs and OSA severity. However, the SRI group was less likely to have REM-related OSA. Conclusions: In PWE and OSA, SRI use is associated with reduced risk of REM-related OSA, and may represent a potential management strategy.

  • Objective : To describe the surgical management and postoperative outcomes in infants with metopic synostosis. Methods : We conducted a 5 years retrospective chart review of patients who underwent surgical correction of metopic synostosis at two university hospitals in Egypt during the period between June 2014 and June 2019. The study is conducted to 18 children. The type of surgical procedures and postoperative outcomes were assessed in all patients. Results : Five cases (27.8%) underwent endoscopic-assisted suturectomy, 10 cases (55.6%) underwent craniofacial reconstruction, and three cases (16.6%) underwent open burring of the metopic ridge. Fifteen patients underwent one surgery and three patients (16.6%) who need second operation. Ten patients (55.6%) had class I Whitaker classification. Conclusion : Regardless of type of surgery, the outcomes of surgical correction of metopic synostosis are excellent with only a few patients require revision or develop major complications.

  • Background: The incidence of skin cancer, which is primarily caused by exposure to ultraviolet radiation, has steadily increased in recent years. The authors of the present study sought to investigate changes in the epidemiology of skin cancer by conducting a retrospective review of patients diagnosed with skin cancer who received related care at a single medical institution. Methods: The present study included patients who were diagnosed with skin cancer and received treatment at Gyeongsang National University Hospital from 2008 to 2018. The site and type of skin cancer, the number of patients with skin cancer each year, the sex and sex ratio of the patients, and changes in patients' age at first diagnosis were examined through retrospective chart reviews. Results: The number of patients with skin cancer significantly increased, but statistically significant changes were not found in patients' sex, skin cancer sites, or the types of skin cancer. However, patients' age at the first diagnosis of skin cancer showed a statistically significant decrease starting in 2015. Conclusion: In this study, the number of patients with skin cancer increased over time. However, patients' age at first diagnosis has decreased since 2015. Therefore, younger patients should take care to prevent skin cancer, and further research on the causes of skin cancer in younger patients is needed.

  • Objectives : This study was conducted to examine the clinical effects of thread embedding acupuncture on lumbar herniated intervertebral disc patients. Methods : This is a retrospective study based on clinical charts. Despite the treatments of acupuncture, pharmacopuncture, herbal medicine, and physical therapy during admission period, 10 lumbar herniated intervertebral disc patients who had shown few improvements in their symptoms were selected as subjects. Thread embedding acupuncture was conducted to reduce patient pain. Patient progress was categorized into three periods based on when the embedding procedure performed. Verbal numeric rating scale (VNRS), Oswestry disability index (ODI), and a 5 step evaluation scale for satisfaction were used to analyze the outcome. Results : Regarding comparison of VNRS improvement rate, both 3 and 6 days after embedding progress showed significant difference compared to before embedding progress. ODI improvement rate showed significant difference only 6 days after embedding progress. Patients' satisfaction with treatment had increased by several degrees. Conclusion : Thread embedding acupuncture for lumbar herniated intervertebral disc patients may be effective in reducing pain and improving their quality of life.

  • This retrospective observational study was aimed to evaluate that Daoyin Exercise therapy improves the symptoms related to lumbar disc herniation. We analyzed the medical records of 7 patients, who satisfied with inclusion and exclusion criteria. The subjects of the study were the patients who were prescribed Daoyin Exercise Therapy and Korean medical treatments for lumbar intervertebral disc herniation at Dunsan Korean Medicine Hospital of Daejeon University from July 25th, 2016 to March 31th, 2017. The effects of Daoyin Exercise Therapy was evaluated by comparing before and after taking Daoyin Exercise Therapy through 0-10 Numeric Rating Scale(NRS), Roland & Morris Disability Questionnaire(RMDQ), Trunk Extension Flexion(TEF) Program, EuroQol five Demension Questionnaire(EQ-5D, EQVAS) of the symptoms including lower back pain. The Daoyin Exercise Therapy combined with Korean medicine treatment reduced NRS($3.357{\pm}3.038$) and RMDQ($9.50{\pm}6.364$), and improved Muscle endurance($44.429{\pm}45.136$), EQ-5D($0.09{\pm}0.12$) and EQVAS($6.571{\pm}19.260$) of the 7 patients without side effects. These results implied that Daoyin Exercise Therapy might helps to improve symptoms of patients with lumbar disc herniation by reducing the symptoms of lower back pain and improving muscle endurance, quality of life, strength enhancement and core muscles.
