This paper aims to investigate whether the sermon of ChatGPT, a form of artificial intelligence(AI) that has emerged with the accelerated development of the Fourth Industrial Revolution in the post-COVID era, aligns with the coherence of Buddhist doctrines. Previous papers have primarily addressed the potential for AI to attain enlightenment. However, this paper intends to assess the coherence of ChatGPT by evaluating its intellectual capabilities. Similar to Buddha’s first sermon after attaining enlightenment, it hold significant importance in Buddhism. To determine whether ChatGPT possesses the ability to match these crucial Buddhist Sermons and the sermon of ChatGPT, sermon answer are derived by asking questions regarding Buddhist doctrines. The answers will be compared with text and academic papers to evaluate their coherence with Buddhist teachings. Considering that significant doctrinal differences exist across different eras of Buddhism, inquiries about doctrines will be categorized into Early Buddhism, Sectarian Buddhism, and Mahāyāna Buddhism. After evaluating the coherence of ChatGPT’s response, the paper intends to explore the potential of ChatGPT as an alternative in the role of Buddhist Sermons. The result indicates that while ChatGPT may exhibit linguistic and Buddhist scholarly errors, it can be viewed positively in its ability to convey the fundamental doctrines. Therefore, this study emphasizes the need for Buddhism to reconsider its perception in oder to recognize and resolve this crisis.

Accidents of worker that occur in isolated places are difficult to rescue, unlike general construction accidents. There is a problem of communication limitation when an accident occurs in an isolated place. Also, it is difficult to search the accident place due to the absence of CCTV. In order to solve these problems, this paper proposes a device that combines IoT technology with a safety helmet, which must be worn in the workplace. The proposed device additionally designs and implements a real-time PPG(Photoplethysmography) sensor, body temperature sensor, accelerometer sensor and a camera sensor on the helmet. The proposed helmet system allows the user and the control center to monitor the state of the worker. In addition, when an abnormal biological signal or fall occurs to the worker, the image is transmitted to the control center. By using the proposed system, it is possible to check the status of the worker in real time, so that it has an advantage that it can cope with the accident quickly 해상과 같이 고립된 장소에서 발생하는 작업자의 사고는 일반적인 건설 사고와는 달리 통신의 제한 등의 문제로 구조에 어려움이 따른다. 또한 CCTV의 부재로 인한 사고 현장의 수색에 어려움이 생긴다. 이러한 문제점을 개선하기 위해 이 논문에서 는 작업 현장에서 필수적으로 착용해야 하는 안전모에 IoT 기술을 접목한 장치를 제안한다. 제안 장치는 기존의 안전모에 심박 센서, 체온 센서, 가속도 센서 및 카메라 센서를 부착하여 설계 및 구현하며, 사용자 및 관제 센터에서 작업자의 상태를 모니터 링 할 수 있게 한다. 또한 작업자에게 비정상적인 생체 신호나 낙상이 발생하면 영상을 관제센터로 전송한다. 제안 시스템을 활 용하면 작업자의 상태를 실시간으로 확인할 수 있으므로 작업자의 사고에 대해 빠른 대처를 할 수 있는 장점을 가진다.

Purpose: We performed a quantitative and qualitative analysis in the Journal of the Korean Society of Traumatology (JKST) by Bibliometrics to know the trends of articles. Methods: We reviewed articles in the JKST retrospectively through 1988 to 2014. Articles were classified into original articles, case reports, review articles, and also it is further classified as topics and the information related to the Department of Medicine of corresponding author. Original article was classified prospective and retrospective studies. Results: 753 studies and average of 27.9 studies per year were posted on JKST. 576 original articles (76.5%) were posted. Retrospective studies around 449 studies (78%) were posted and there were about 35 descript studies and 541 analytic studies. The most common themes were related to abdominal trauma, 144 pieces, 95 pieces following damage to the chest and the 84 pieces of special order of trauma. Emergency department had the highest case whereas general surgery came to the second place. Conclusion: Recently, there has been reduced proportion of original article in JKST. It was not possible to evaluate the Korea Citation index journals due to the fact that it does not correspond to listed register Journal of National Foundation of Korea. There will be the need for the effort to improve the maintenance of the posted article number, as well as the qualitative development of the posted articles. [ J Trauma Inj 2015; 28: 182-189 ]

액스선 형광에 의한 Ni-Fe-Cr계의 내부조직 효과에 관한 연구

예진해 安東大學 1985 安東大學 論文集 Vol.7 No.1

The purpose of this study is to obtain X-ray absorption-enhancement coefficient of the matix by use of metallic oxides mixtuse so that both constituent and composition can be easily varied and to examine applicability of these coefficient to metallic ingot samples for composition measurements. Instead of using the coefficient obtained from the ingots, competition of alloy ingots and powdered oxide termary have been calculated by usage of the coefficients of obtained from the oxide binany mixture and the concentration are found to be within 2.2~4.5% of relative errors.

X-선형광분석에서 matrix 효과의 실험계수 보정

예진해 安東大學 1996 安東大學 論文集 Vol.18 No.1

The matric effect should be reduced to the minimum in order to examine the proper contents of analytic elements in the x-ray spectra-analytical method. To reduce this matrix effect, a formula is established in relation to several factors such as the x-ray fluorescent intensity of a certain element in a well-known sample, the contents of the element, the reflex principle of x-ray radiation, and the characteristic that the adjacent matrix reduces or increases the analytic line intensity in proportion to the differences in the mass absorption coefficient of each element. It is found that effect of F_(e) and C_(r) on N_(1) are absorption rich and effects of F_(e) and N_(1) on C_(r) are enhancement rich, wheres N_(1) enhances Fe fluorescence but C_(r) absolves F_(e) K_(a) line. And the x-ray fluorescence intensities were compared and analyzed between the metallic oxides and the ingot samples.

엑스선螢光分析에서 金屬三成分系의 매트릭스 效果에 關한 硏究

예진해 安東大學 1987 安東大學 論文集 Vol.9 No.1

엑스선 형광분광법은 실험 조작이 비교적 간편하고 신속성을 가지며 시료의 비파괴적인 장점이 있는 반면 분석원소의 함유량과 엑스선 형광세기 간에 직선관계를 얻기 어려운 점이 문제이다. 엑스선 형광세기는 해당 분석원소의 함유량에 비례하지만,공존하는 다른 원소들의 함유량에도 영향을 받게 되는데, 이를 매트릭스 효과라고 한다. 따라서, 성분 원소의 정확한 함유량을 구하려면, 이 매트릭스 효과를 줄이거나 보정해 주어야 한다. 이 방법은 여러 가지 형태로 보고 되어 있다. 본 실험에서는 표준물질은 2성분계에서 쉽게 자작할 수 있는 금속 산화를 분말을 시료로 하여 반실험식을 이용해서 매트릭스 효과 보정계수를 구하였고 3성분계 시료는 금속 분말 산화물과 금속 합금 덩어리인 B.A.S및 J.A.E.R.I의 표준시료를 사용했다. 2성분계 금속 분말 산화물에서 얻은 매트릭스 효과 제수의 성질과 또 이 매트릭스 효과계수로서 3성분계인 분말 산화물 시료의 합금 덩어리 시료의 미지 성분 함량을 계산해 낼 수 있는지를 조사 하였다. X-ray fluorescence analytical technique is well known method for nondistructive analysis of metallic alloyes. However, there are some difficulties in concentration measurement of the constituents due to the fact that interaction of not only primary X-ray but also the secondary X-rays emitted by the elements exists among the neighbouring constituents. The purpose of this study is to obtain X-ray absorption-enhancement coefficients of the matrix by use of metallic oxides mixture so that both constituent and composition can be easily varied and to examine applicability of these coefficients to metallic ingot samples for composition measurements. Metallic oxide binary and ternary mixture samples have been prepared by mixing them to make 10, 20, 30?to 90% compositions then by pressing it at 30tons of 300 mesh powder for 5 minutes in dimensions of 40mm diameter and 10mm thickness. The matrix effect coefficients, an, obtained by use of Birks equation are, respectively, 1.055, 0.566, 2.770 for a_(FeFe), a_(FeNi), a_(FeCr); 2.616, 0.987, 2.070 for a_(NiFe), a_(NiNi), a_(NiCr); and 0.645, 0.627, 1.002 for a_(CrFe), a_(CrNi), a_(CrCr). It is found that effects of Fe and Cr on Ni are absorption rich and effect of Fe and Ni on Cr are enhancement rich, whereas Ni enhances Fe fluorescence but Cr absorbes Fe Ka line. Matrix effect coefficients are also obtained by using B. A. S. standard ingot samples. However, the coefficients calculated are widely dissagreed among the selected sets of ingot samples. Instead of using the coefficients obtained from the ingots, composition of the alloy ingots have been calculated by usage of the coefficients obtained from the oxide binary mixture and the concentration estimations are found to be within ±2% of relative errors.
