치과분야 영상검사 피폭선량모니터링을 통한 선량 최적화 방안

이채나 대한치과의사협회 2024 대한치과의사협회지 Vol.62 No.2

Along with the advancement of dental x-ray equipment, the use of diagnostic radiation has been rapidly increasing. Accordingly, concerns about radiation exposure are increasing. In particular, imaging examinations in the dental field have a low individual radiation exposure. However, the frequency of the examinations is high. Also, due to the abundant usage of dental CBCT, concerns has been widely spread across the users and the nation. In response to this, there has been a need to establish a dose monitoring system for dental x-ray equipment. Therefore, the purpose of this study was to establish of a national dose monitoring system for imaging examinations in the dentistry. For the system establishment, the structure of intraoral, panoramic radiography and CBCT system was surveyed and the integrated data collection plan was prepared. Based on this, dose monitoring system, which can be utilized for nation-wide, was established and a pilot operation was conducted. In order to continuously expand the system in the future, system supplements should be confirmed through gathering expert opinions.

이채나,김조은,Won-Jin Yi,허민석,Sam-Sun Lee,Soon-Chul Choi,한상선 대한영상치의학회 2020 Imaging Science in Dentistry Vol.50 No.3

Acquired facial lipoatrophy is a rare disease with an unclear etiology and pathological pathway. The distinct causative factors of this disease have been not elucidated, but it is suspected to be associated with immune systemrelated diseases, most notably AIDS. Although the management of facial lipoatrophy is very important for patients’ social life and mental health, no treatment framework has been developed due to the unknown nature of the disease manifestation. The present case report was designed to provide sequential imaging to visualize the disease progression. The clinical backgrounds of the patients are also introduced, helping characterize this disease entity more clearly for maxillofacial specialists

Therapeutic effect of intraductal irrigation of the salivary gland: A technical report

이채나,김조은,허경회,이원진,허민석,이삼선,최순철 대한영상치의학회 2017 Imaging Science in Dentistry Vol.47 No.2

Purpose: Obstructive and inflammatory disease often occurs in the major salivary glands, and no predictive treatment has yet been developed for this condition. The aim of this report was to introduce an intraductal irrigation procedure and to illustrate its application to practical patient cases. Materials and Methods: Two patients complaining of pain and swelling in the parotid gland during meals who underwent sialography were diagnosed as having sialodochitis with sialadenitis. Intraductal irrigation was then performed on the parotid gland on the side of the complaint. The irrigation procedure was conducted in the same manner as the sialography procedure, except that saline was used as the filling solution. Symptom severity was evaluated with a numerical rating scale (NRS) at the initial visit and a month after the irrigation. Results: The initial NRS value of patient 1 was 10. The value decreased to 6 and then to 0 after 2 irrigation procedures. The NRS value of patient 2 regarding the symptoms involving the left parotid gland decreased from 4-5 to 1 after 4 irrigation procedures performed at 1-month intervals. Conclusion: Intraductal irrigation of the salivary gland may be a simple, safe, and effective treatment option for patients with obstructive and inflammatory disease of the salivary gland that is capable of resolving their symptoms.

이채나,이삼선,김조은,Khanthaly Symkhampha,이우진,허경회,이원진,허민석,최순철,염헌영 대한영상치의학회 2016 Imaging Science in Dentistry Vol.46 No.2

Purpose: The current study investigates the feasibility of a platform for a nationwide dose monitoring system for dental radiography. The essential elements for an unerring system are also assessed. Materials and Methods: An intraoral radiographic machine with 14 X-ray generators and five sensors, 45 panoramic radiographic machines, and 23 cone-beam computed tomography (CBCT) models used in Korean dental clinics were surveyed to investigate the type of dose report. A main server for storing the dose data from each radiographic machine was prepared. The dose report transfer pathways from the radiographic machine to the main sever were constructed. An effective dose calculation method was created based on the machine specifications and the exposure parameters of three intraoral radiographic machines, five panoramic radiographic machines, and four CBCTs. A viewing system was developed for both dentists and patients to view the calculated effective dose. Each procedure and the main server were integrated into one system. Results: The dose data from each type of radiographic machine was successfully transferred to the main server and converted into an effective dose. The effective dose stored in the main server is automatically connected to a viewing program for dentist and patient access. Conclusion: A patient radiation dose monitoring system is feasible for dental clinics. Future research in cooperation with clinicians, industry, and radiologists is needed to ensure format convertibility for an efficient dose monitoring system to monitor unexpected radiation dose.

Organized hematoma of temporomandibular joint

이채나,육종인,한상선 대한영상치의학회 2018 Imaging Science in Dentistry Vol.48 No.1

Organized hematoma is a pseudo-tumorous lesion mostly occurs at sinonasal cavity and often confused with malignant neoplasm. The initiation of this lesion is blood accumulation, probably due to trauma, and this hematoma develops into organized hematoma as it encapsulated with fibrous band and neo-vascularized. Since it is uninformed at temporomandibular joint (TMJ) region, imaging diagnosis might be challenging. Also, delayed detection of mass involving TMJ is not uncommon due to confusion with joint disorder. Thus, this report introduced the rare pathology, organized hematoma on TMJ with advanced imaging features. Also, diagnostic point for early detection was described for the TMJ tumors and pseudo-tumors considering complexity of surgical intervention in this region.

코헨의 종차별 옹호논증은 옳은가? - 도덕적 차이 논증과 종류 논증을 중심으로

이채리 범한철학회 2015 汎韓哲學 Vol.77 No.2

이 논문의 목적은 코헨의 도덕적 차이 논증과 종류논증이 정당하지 않음을 비판함에 있다. 반종차별주의자들은 종차별주의가 인종차별주의나 성차별주의와 마찬가지로 부당하며((A1)), 종차별주의의 주장에 따라 동물이 권리를 가질 수 없다면, 가장자리 인간 역시 권리를 가질 수 없다((A2))고 비판한다. (A1)에 대해 코헨은 동물과 인간 사이에는 도덕적 능력의 차이가 있으므로 동물에 대한 차별은 정당하다는 도덕적 차이 논증을 제시하며, (A2)에 대해서는 가장자리 인간은 인간의 종류에 속하므로 권리를 가진다는 종류논증을 제시한다. 그러나 도덕적 차이 논증은 고통과 상관이 없는 기준으로 고통을 차별하는 무관함의 오류를 범한다. 그리고 종류논증은 두 개의 권리 조건을 비일관되게 적용하고, 모호한 ‘종류’ 개념에 의존하며, 집단의 능력을 근거로 실제적으로 능력이 뛰어난 개인을 차별하는 부당한 원리에 의존한다. 따라서 필자는 도덕적 차이 논증과 종류논증이 (A1)과 (A2)에 대한 정당한 대답이 될 수 없으며, 인간은 권리를 가지지만 동물은 어떤 권리도 가질 수 없다는 코헨의 종차별주의는 옹호될 수 없다고 논한다. The purpose of this thesis is to criticize that Cohen's moral difference argument and kind argument can’t be a right answer to anti-speciesist’s criticism (A1) and (A2). Anti-speciesists criticize that speciesism, like racism or sexism, is unfair(A1) and that if animals cannot have their rights, marginal humans can’t, either(A2). Regarding (A1), Cohen presents his moral difference argument that discrimination of animals is fair since there is difference in moral capacity between humans and animals. Regarding (A2), he presents his kind argument that marginal humans own their rights since they belong to human kind. However, I criticize that moral difference argument is a standard unrelated to pain, and that kind argument presents inconsistent conditions and (4) is not inevitably true but a morally unfair principle. Accordingly, I insist that moral difference argument and kind argument can’t be valid answer to (A1) and (A2).

사이버 공간의 페미니즘적 의미

이채리 ( Chae Lee Lee ) 한국과학철학회 2007 과학철학 Vol.10 No.2

The purpose of this study is to inquire and analyze feministic view on cyberspace on the base of the opinion of Dana J. Haraway and Sadie Plant so that assess feministic implication of cyberspace. Haraway has the view that human being is a cyborg, the hybrid of machine and organism in cyberspace, and the gender dualism is broken up in the cyborg. Plant suggests that the system of cyberspace is feminine so it is feministic system for woman. However unlike their theory, the cyberspace is ruled by gender dualism at present and there is patriarchal phenomenon. I think that this phenomenon shows the flaw of Haraway`s theory which prospects breaking of boundary between female and male through breaking of boundary between machine and organism. And I understand that there is a fault in Plant`s assumption which insists feminine system imply anti-patriarchal system. In this process of study, I would like to point out that the view of Haraway and Plant, which understands cyberspace as feministic utopia, is too optimistic and so review cyberspace to see how much it has feministic implication at present.
