This study delved deeply into the reflective and self-reflective narratives of a special education teacher with a major in art, exploring concerns about the identity and role of special education teachers in special schools, difficulties in art classes, and reflections on education. Additionally, it aimed to examine how the artistic identity of a researcher majoring in art influences art classes for students with disabilities. Through the method of art-based autoethnography, the researcher sought to discover and express the process of self-reflection and contemplation on their teaching through the visual art genre of 'painting,' raising issues and vividly expressing the researcher's experiences and emotions. This research observed and described from a first-person perspective using the method of reflective journaling, aiming to find points of contact with the societal and cultural aspects of the researcher's context. This study provided an opportunity to explore the distinctiveness of art education for students with disabilities and raised discussions about the art education expertise of special education teachers.

Enzymatic treatment was conducted to hydrolyze pure cellulose nanofiber (PCNF), holocellulose nanofiber (HCNF), and lignocellulose nanofiber (LCNF) for 6, 24 and 72 hours and thus-obtained nanofibers (1, 3, 5, 10 wt%) were used to reinforce polyvinyl alcohol (PVA). Glucose production yield was increased by enzymatic hydrolysis. Tensile strength and elastic modulus of all PVA nanocomposite reinforced three nanofibers were improved by increasing enzymatic hydrolysis time of nanofibers and these values were higher in order of nanocomposite reinforced with PCNF>HCNF >LCNF. Furthermore, tensile properties of nanocomposite with PCNF were increased by nanofiber content. Thermal stability of PVA was improved by adding nanofibers and by increasing nanofiber content.

ObjectiveaaThe lifetime prevalence of alcohol dependence in South Korea remains higher than other countries. The aim of our study is to identify factors associated with remission from alcohol dependence. MethodsaaData from the Korean Epidemiological Catchment Area-Replication (KECA-R) study were used in our study. The Korean version of the Composite International Diagnostic Interview 2.1 (K-CIDI 2.1) was administered. Remission was defined as having no symptom of alcohol dependence for 12 months or longer at the time of the interview. Demographic and clinical variables putatively associated with remission from alcohol dependence were examined by t-test, chi-square-test and logistic regression analysis. ResultsaaThe lifetime prevalence rate of alcohol dependence was 7.0%. Among them, 3.2% of the subjects were diagnosed with active alcohol dependence in the previous 12 months, and 3.8% were found to be in remission. Subjects in 35- to 44-year-old group, not living with partner group, and lower level of educational attainment group were more likely to be in the active alcohol dependence state. Of the comorbid mental disorders, dysthymia, anxiety disorder, nicotine use, and nicotine dependence were more common among the actively alcohol-dependent subjects. ConclusionaaThere is considerable level of recovery from alcohol dependence. Attention to factors associated with remission from alcohol dependence may be important in designing more effective treatment and prevention programs in this high-risk population.
Ionic Liquid Pretreatment of Lignocellulosic Biomass

Lignocellulosic biomass has recalcitrant characteristics against chemical and biological conversion due to its structural heterogeneity and complexity. The pretreatment process to overcome these recalcitrant properties is essential, especially for the biochemical conversion of lignocellulosic biomass. In recent years, pretreatment methods using ionic liquids (ILs) and deep eutectic solvents (DESs) as the green solvent has attracted great attention because of their advantages such as easy recovery, chemical stability, temperature stability, nonflammability, low vapor pressure, and wide liquids range. However, there are some limitations such as high viscosity, poor economical feasibility, etc. to be solved for practical use. This paper reviewed the research activities on the pretreatment effect of various ILs including DESs and their co-solvents with organic solvents on the enzymatic saccharification efficiency of lignocellulosic biomass and the nanocellulose preparation from the pretreated products.
