  • Objectives: This study was based on the occurrence of a coffee roasting process-related disorder(bronchiolitis obliterans; published by NIOSH in the US) among workers exposed to chemicals called diacetyl in a coffee processing facility. Flavorings added to coffee contain diacetyl and 2,3-pentanedione, all of which are subject to exposure in a number of food manufacturing processes, including coffee roasting, grinding, and packaging. Therefore, this study aims to review the toxicity to workers related to food processing and food additive manufacturing to prevent occupational diseases. Methods: We surveyed the related literature, domestic and international references, and the status of relevant domestic and foreign professional organizations. The present situation of workers was investigated by reviewing literature on the safety and health of workers in the coffee roasting process using domestic and foreign literature and presentations. Expert advisory opinions were reflected, and experts were consulted by participating in domestic and overseas academic conferences. Results: Most of the fragrance materials for coffee were harmful and hazardous substances according to the GHS classification, and research was carried out through a second external consultation. A literature review on the measurement of air pollutant emissions from coffee roasters and the estimation of air pollutant emissions during coffee roasting examined the characteristics of pollutants emitted during coffee roasting. Conclusions: Two chemicals identified as causing bronchiolitis obliterans in the coffee roasting process are believed to explain why the disease is difficult to treat. This information can be used effectively in the future prevention of this disease. Future studies should clearly identify the potential for toxicity of alpha-diketones and the bases of OELs in relation to the occurrence of obstructive bronchiolitis, including measurement of various organic compounds and alpha-diketones from ground coffee, as well as various coffee grinds and coffee bean varieties. In particular, it is necessary to clarify the current understanding of the dose-response relationship between alpha-diketone and lung disease in workers involved in coffee roasting.

  • It is effective personally and nationally that dental professionals provide oral health education to North Korean defectors. This study aims to examine literature on oral health education for North Korean defectors. The method of this study is a scoping review, which is a method for qualitatively reviewing and reinterpreting previous studies with the literature review method. There were differences in age and period of settling in South Korea among the study participants of the literature. It be divided into a study that evaluated the annual oral health education experience rate, and a study that applied an educational program and evaluated its effectiveness. It showed positive results in all literature for various effects evaluation variables such as dental health, periodontal health, and oral health knowledge. This study is significant in that it sought the direction of development of oral health education for North Korean defectors. It is suggested when planning oral health education for North Korean defectors, it is necessary to establish a differentiated approach strategy in consideration of oral health gaps, cultural differences such as language, psychological characteristics according to the settling period in South Korea, and age.

  • Purpose : The purpose of this study provided an overview of the general status and recent intervention approaches in overseas research related to feeding problems in children with autism spectrum disorder (ASD). This review aims to explore interventions for feeding problems in order to provide higher quality follow-up research directions and implications, particularly focusing on providing recommendations for future research in the context of domestic studies. Methods : Analyzing studies published in international journals from 2017 to 2023. This review involved six selected articles, through Embase, Pubmed, RISS, KISS database search engine. A literature analysis that includes inclusion and exclusion criteria, six selected articles were examined. The literature analysis categorized the general status of the research and intervention approaches and treatment components into intervention, treatment settings and therapists, and dependent variables, respectively. Results : Among feeding intervention approaches, parent education interventions based on behavioral therapy had the highest proportion, followed by multidisciplinary interventions. To maintain the effectiveness of interventions over the long term and to generalize them to the home environment, parent education that utilizes parents as mediators is considered a crucial factor. The most commonly observed effects as dependent variables were changes in the consumption of disliked foods, health foods and alterations in feeding behavior. Conclusion : This study introduces various intervention approaches for addressing feeding problems in children with autism spectrum disorder (ASD), focusing on the positive effects demonstrated by active intervention research in abroad. Furthermore, it underscores the need for additional research in Korea to validate the efficacy of these feeding intervention methods. Lastly, the study outlines future research directions aimed at developing feeding programs to support children with ASD and their families coping with feeding issues.

  • Purpose: This study aimed to investigate the current state and trends of health literacy research considering migrants living in South Korea. Methods: A review of the literature was conducted using electronic data base and citation tracking. A total of 82 articles were identified, of which 16 articles that met the inclusion criteria were selected for review. Two authors reviewed the articles independently using a matrix table and then examined four aspects of the studies jointly: research method, immigrant characteristics, health literacy assessment, and main findings. Results: Most of the articles (n=13) were descriptive studies and three were methodology studies for instrument development. Of the 13 studies, eight involved female immigrants, four of health literacy involved migrant workers, and four concerned North Korean Refugees. A total of eight types of health literacy assessment tools were used. Sufficient samples and sampling methods were lacking at the population level. Conclusion: The results of the review generally showed that the health literacy of immigrants was lower than that of native South Koreans, and that there was a difference between nationality and gender among immigrants; however, further research is needed to review a larger sample with a validated instrument.

  • Objectives: Adjusting for potential confounders is crucial for producing valuable evidence in outcome studies. Although numerous studies have been published using the Korea National Health Insurance Claim Database, no study has critically reviewed the methods used to adjust for confounders. This study aimed to review these studies and suggest methods and applications to adjust for confounders. Methods: We conducted a literature search of electronic databases, including PubMed and Embase, from January 1, 2021 to December 31, 2022. In total, 278 studies were retrieved. Eligibility criteria were published in English and outcome studies. A literature search and article screening were independently performed by 2 authors and finally, 173 of 278 studies were included. Results: Thirty-nine studies used matching at the study design stage, and 171 adjusted for confounders using regression analysis or propensity scores at the analysis stage. Of these, 125 conducted regression analyses based on the study questions. Propensity score matching was the most common method involving propensity scores. A total of 171 studies included age and/or sex as confounders. Comorbidities and healthcare utilization, including medications and procedures, were used as confounders in 146 and 82 studies, respectively. Conclusions: This is the first review to address the methods and applications used to adjust for confounders in recently published studies. Our results indicate that all studies adjusted for confounders with appropriate study designs and statistical methodologies; however, a thorough understanding and careful application of confounding variables are required to avoid erroneous results.

  • In this study, the picture book reviews shown in Korean periodicals were analyzed to provide the developmental foundation for picture book reviews and expand the professional area of librarians as the producers of book review. Through the literature research and the Delphi Technique the desirable standard of book reviews was suggested, the contents in domestic book review mediums were analyzed for the rightness of describing based on the standard of the book review and henceforward the way of development was suggested. The result from analysis of book review showed that the outstanding book reviews should be more produced based on the desirable standard of book review and the evaluative statements should be developed more than the descriptive statements. Depending on the mediums the contents of the book review were different by the book reviewers' occupations, so the book reviewers should develop their professional knowledges in literature and art. Because the longer book review made the outstanding book review with the rightness of the desirable standard of book review, the certain quantity of book review should be needed and the role of librarians as the book reviewers should be further extended.

  • This study aims to understand the concept of 'ruralism' in Korea by comparing with 'rurality' which were dealt with in various fields related to rural areas in Korea. This study conducted a systematic literature review as a methodology. The process is defining key questions, searching for documents, classifying documents, extracting data, and presenting results. The key questions were set to 'How has the term 'ruralism' been used in various studies?' and 'How can the concept of rurality in Korea be organized?' according to the purpose of the study. The study retrieved literature by searching on Korean academic database, RISS and DBpia, using the five keywords '농촌성', '농촌다움', '농촌다운', 'Rurality,' and 'Ruralism.' The search yielded 1,014 documents which were thereafter screened by systematic literature review process. After sifting, only 31 publications were found suitable for inclusion in the final analysis. This study organized them into four categories: rural concept, rural landscape, rural tourism, and rural development. The literature divided into four types. Type I is a study that deals only with economy·society among studies related to rurality, Type II is a study that deals with both the economic·social and physical environment, Type III is a study that deals with the physical environment of a rural area and presents the rural planning principle as maintenance and preservation. Finally, Type IV is a study that presents ruralism as a new rural planning principle for a future rural area. In the end, the study discussed some implications on defining ruralism in Korea.

  • Purpose: Ectopic eruption can be defined as the emergence of a tooth in an abnormal location, where the tooth does not follow its typical eruption pathway. While ectopic eruption within the dentate region is well-documented in the literature, ectopic eruption in non-dentate regions is relatively rare. This study aimed to report 6 cases of ectopic teeth and present a systematic review of the English-language literature on ectopic teeth, emphasizing demographic characteristics, radiographic features, potential complications, and treatment options. Materials and Methods: A literature search was conducted using the PubMed, Medline, Web of Science, and Cochrane databases. The demographic data and radiographic findings of patients presenting with ectopic teeth were recorded. Results: The literature review yielded 61 cases of ectopic teeth, with patients ranging in age from 3 to 74 years. The findings from these previously reported cases demonstrated that the most common location for ectopic teeth was the maxillary sinus, which is consistent with this case series. The Pearson chi-square test was performed to evaluate the correlation between age and location of ectopic teeth, and the results were found to be statistically significant (P<0.05). However, no statistically significant relationship was observed between sex and the location of ectopic teeth. Conclusion: The distinct features of these cases warrant reporting. This study presents the first case of supernumerary teeth in the condyle without any associated pathosis. Another notable characteristic is the pre-eruptive resorption of 2 inverted supernumerary teeth ectopically located in the palate, which predisposes to sinus opacification.

  • The tympanic plate is a small part of the temporal bone that separates the mandibular condyle from the external auditory canal. Fracture of this small plate is rare and usually associated with other bony fractures, mainly temporal and mandibular bone. There is a limited amount of literature on this subject, which increases the chance of cases being overlooked by physicians and radiologists. This is further supported by purely isolated cases of tympanic plate fracture without evidence of other bony fractures. Cone-beam computed tomography is an investigative three-dimensional imaging modality that can be used to detect fine structures and fractures in maxillofacial trauma. This article presents four cases of isolated tympanic plate fracture diagnosed by cone-beam computed tomography with no evidence of fracture involving other bones and review of the literature.

  • It is not an overstatement to say the factory are the number one cause in creating environmental load. However, only a few studies have been done upto this date on environmentally friendly factory. Thus, This study is to present the characteristics of environmentally friendly factory. A survey of current literatures and cases show the characteristics of environmentally friendly factories and buildings and environment assessment method and plan. To better measure the environmentally friendly qualities as written in literature across the globe, classification system was constructed. The classification system was made and important factors were found based on the precedent paper on environmentally friendly building plan and environment assessment method at building and cases and abroad in the literature review. The classification used 4 different sectors : Land & Transportation, Architectural Planning Technique, Environment & Equipment, Energy & Material. Within these 4 sectors 33 discrete factors are applied to the factory according to literature and case review and specialist advice.
