인주 전색제에 따른 인영(印影)의 변화 특성

류송이 한국문화재보존과학회 2022 보존과학회지 Vol.38 No.5

인주의 재료에 따라 색상, 압인 특성, 손상 양상 등에 있어 다양한 형상적 차이를 보이는 만큼 인영의 형상을 좌우하는 데 있어 인주의 재료적 특성이 중요하다. 문헌의 인주 제조의 기록 중 큰 차이는 전색제의 종류가 기름과 아교의 차이임을 확인하였다. 따라서 본 연구에서 는 인주의 전색제별 인영의 특성을 확인하고, 환경 조건에 따라 인영에서 나타나는 형상 및 이화학적 변화 양상을 비교하였으며 미생물 발생도 평가를 실시하였다. 아교 전색제 인주의 인영은 표면에서 섬유질 공극 사이로 안료가 메워지는 특성이 존재하고 열화를 진행함에 따라 인영의 자체 손상은 미비하였다. 피마자유 전색제 인주의 인영은 표면은 인주가 지지체 섬유질 전체에 흡착되는 것을 확인하였고 압인되면서 인영 주변으로 기름이 확산됨에 따라 지지체의 황변을 일으키는 요소일 가능성을 확인하였다. 인주와 인영의 의미, 광물 안료 요소 외에도 유지의 종류, 아교 및 유지를 혼합, 인장 재질, 함유제에 따른 추가 연구 등 종합적인 인주의 연구가 필요하며 고서화 문화재의 인영 보존 관리 및 처리, 문화재 진위 판정 등에 선행자료로 활용될 수 있을 것으로 기대된다.

The purpose of this study was to investigate the student's sensibility factors and preferences for casual shirts with check pattern such as gingham check, window pane check, burberry check, plaid check. A questionnaire survey was conducted on 228 university students(male students 36.4%, female students 63.4%) in Cheongju. F-test, t-test correlation coefficient and factor analysis were used for data analysis. The sensibility for casual shirts with check pattern were classified into four factors: 'modern/active', 'confident', 'professional' and 'relax'. There were significant differences according to the check pattern in the sensibility for the casual shirts. The plaid check pattern were evaluated to be more modern/active sensibility than the others, and the burberry check pattern the more confident sensibility. Also, the window pane check pattern were evaluated to be more professional sensibility than the others, and the gingham check pattern the more relax sensibility. There were partially significant relationships between the personal properties of university students and the preferences for casual shirts with check pattern.

박송이,이상화,김민정,지기환,류지호 한국보건의료인국가시험원 2022 보건의료교육평가 Vol.19 No.-

Purpose This study investigated whether the reliability was acceptable when the number of cases in the objective structured clinical examination (OSCE) decreased from 12 to 8 using generalizability theory (GT). Methods This psychometric study analyzed the OSCE data of 439 fourth-year medical students conducted in the Busan and Gyeongnam areas of South Korea from July 12 to 15, 2021. The generalizability study (G-study) considered 3 facets—students (p), cases (c), and items (i)—and designed the analysis as p×(i:c) due to items being nested in a case. The acceptable generalizability (G) coefficient was set to 0.70. The G-study and decision study (D-study) were performed using G String IV ver. 6.3.8 (Papawork, Hamilton, ON, Canada). Results All G coefficients except for July 14 (0.69) were above 0.70. The major sources of variance components (VCs) were items nested in cases (i:c), from 51.34% to 57.70%, and residual error (pi:c), from 39.55% to 43.26%. The proportion of VCs in cases was negligible, ranging from 0% to 2.03%. Conclusion The case numbers decreased in the 2021 Busan and Gyeongnam OSCE. However, the reliability was acceptable. In the D-study, reliability was maintained at 0.70 or higher if there were more than 21 items/case in 8 cases and more than 18 items/case in 9 cases. However, according to the G-study, increasing the number of items nested in cases rather than the number of cases could further improve reliability. The consortium needs to maintain a case bank with various items to implement a reliable blueprinting combination for the OSCE.

박송이,류지호,김선휴,최병호,김성춘,임대성,배병관 대한응급의학회 2020 대한응급의학회지 Vol.31 No.5

Objective: This study investigated the current work status of emergency medical services (EMS) personnel and the differences in perception between EMS personnel and medical directors (MD) regarding on-line medical oversight in a province. Methods: A total of 1,781 EMS personnel and 51 medical directors were surveyed. The questionnaire consisted of the basic demographic data, work status, perception of on-line medical oversight, and the upcoming national pilot project of the expanding firefighter EMS personnel’s clinical scope. The survey was conducted from May 17 to 27, 2019. Results: The response rates for EMS personnel and MD were 73.7% and 65.3%, respectively. Of the local EMS personnel, 86.8% were male. The average age and field career was 33.5±6.2 years and 50 months, respectively. The proportion of nurse and 1st-grade emergency medical technicians were 30.6% and 35.7%. The EMS personnel and MD answered ‘on-scene basic life support’ and ‘patient’s refusal of transport’, respectively, as the most unnecessary medical oversight. Both responded to the main problem of current medical oversight as ‘request for unnecessary medical oversight.’ EMS personnel responded that all items in the national pilot project of expanding firefighter EMS personnel’s clinical scope would be helpful, while MD reported that only ‘use of epinephrine in anaphylactic patient’ and ‘use of pre-hospital 12 lead electrocardiogram in chest pain patient’ would helpful (P<0.01). Conclusion: There was a certain difference in perception of the most unnecessary medical oversight and the upcoming national pilot project of expanding the clinical scope of firefighter EMS personnel between EMS personnel and MD.

이채훈,류송이,이한형,김효윤,김성미,정용재 한국문화재보존과학회 2020 보존과학회지 Vol.36 No.5

본 연구에서는 화협옹주 회곽함에서 출토된 화장품 중 갈색 고체 잔여물이 나타난 화장 품을 중점으로 연구를 진행하였다. 이 화장품은 1752년 부장된 회곽함 안의 청화백자합에서 출토되었다. 국립고궁박물관에서는 유물분석과 문헌조사를 진행하였다. 이를 바탕으로 출토화 장품의 원재료와 제조법을 추정하여 크림 형태의 화장품재현을 시도하였다. 이후 출토품과 유사한 열화 양상을 확인하기 위하여 고온, 자외선, 이산화탄소 조건에서 열화를 시행하였다. 이에 따른 변화와 화장품으로써의 효과를 확인하고자 과학적 분석과 기능성 평가를 진행하였다. 유지류가 높은 비율로 혼합된 재현품에서는 고온열화가 진행됨에 따라 색차값이 약 32 차이가 나타났고, O-H 결합과 C=C 결합에서 화학적 변화가 발생하여 유지류 산화가 발생한 것을 확인할 수 있었다. 또한, 자외선 열화를 통해서는 pH 값이 노출 시간에 따라 산성화되는 것을 확인할수 있었다. 재현품의 기능성 평가로 진행한 차폐율은 현대 화장품의 차폐 기준치보다 낮게 나타 났다. This study focused on analyzing solid brown cosmetic residues that were excavated from the tomb of the Hwahyeop princess. The cosmetics had been buried in 1752 in Cheonghwa Baekja (small porcelain jars) within a Huigwakham (a stone box sealed with lime). A literature search and chemical analyses of the relics were conducted at the National Palace Museum of Korea. Based on the results of these analyses, raw materials and manufacturing methods for reproduction of the cosmetic were selected and then cream-form cosmetics were prepared. Ag ing tests using heat, ultraviolet (UV) radiation, and CO2 were carried out to emulate the deterioration of the excavated cosmetics. Further chemical analyses and functionality tests were performed to evaluate changes from the tests and the effect as a cosmetic. As heat aging progressed, among the reproduced cosmetics, the one which has a high proposition of oil showed a color difference value of 32; the oxidation of oils involved chemical changes in O-H and C=C groups. As the cosmetic cream deteriorated under UV aging, the pH value became acidic. The result of the functional coverage test of the reproduced cosmetic cream was lower than the standard coverage ratio of modern cosmetics.

Third, the influence of male university students’ internet pornography exposures on sexual awareness and sexual attitude showed significant difference in sexual awareness according to ‘change in sexual behavior after watching pornography’. There was significant difference in 3 factors of sexual attitude according to exposure of university male students to internet pornography. Conclusion: This study suggest that sexual education development for male university students is needed in order to establish upright sexual values that can lead to healthy sexual behaviors.

구급대원 현장응급처치 숙련도에 대한 구급대원과 지도의사의 인식 비교

임대성,김성춘,박송이,류지호,배병관,김선휴,최병호,양태원,김정은,강지훈,김민희,김이민,조영학,정봉규,박재기,차준재 대한응급의학회 2020 대한응급의학회지 Vol.31 No.4

Objective: This study aimed to investigate the perception of emergency medical service (EMS) providers and medical directors toward the field skill proficiency of EMS providers. We further examined differences in perception according to the certification and hospital career of individuals. Methods: This survey was conducted enrolling all active EMS providers in Busan, Ulsan, and Gyeongnam, as well as emergency physicians who participated in direct medical direction. Pre-developed questionnaires were sent as text messages to individual EMS providers and emergency physicians using an internet-based survey tool (Google Forms). Questionnaires were composed of 25 items in 7 categories: “airway management”, “ventilatory support”, “circulatory support”, “field assessment and management of trauma patients”, “field assessment and management of patients with chest pain”, “field assessment and management of patients with neurologic symptoms”, and “other items”. The response was based on a five-point Likert scale, where 0 score indicated no experience at all. Results: The questionnaire was distributed to 1,781 EMS providers and 52 medical directors; of these, 1,314 (73.7%) EMS providers and 34 (65.3%) medical directors completed the survey. EMS providers rated themselves as above average (3 points) for most of the questions. However, the majority responded that they had no experience or low proficiency in endotracheal intubation and prehospital delivery (median 2; interquartile range [IQR], 0-3). Conversely, medical directors assessed the EMS provider’s proficiency as above average in use of I-gel, recognition of hypoglycemia, field management of trauma patients, use of oropharyngeal and nasopharyngeal airway, use of laryngeal mask airway, and optimal oxygen supply (median, 4; IQR, 3-4), but responded with low scores for most other questions. Based on the EMS provider certification, nurses scored themselves more proficient than level-1 emergency medical technicians (EMTs) for intravenous access (P<0.001), whereas level-1 EMTs recognized themselves more proficient than nurses for endotracheal intubation (P<0.001), use of Magill forceps (P=0.004), and pediatric cardiopulmonary resuscitation (P<0.001). Conclusion: This study recognized the discrepancies in the perception of EMS provider’s field skill proficiency, as perceived by EMS providers and medical directors, and between level-1 EMTs and nurses. We propose that regional EMS authorities need to make persistent efforts to narrow these perception gaps through effective educational programs for EMS providers and medical directors.
