Objectives & Methods : This study aims to investigate the application of the principle of the mutual communication between organ and bowel(臟腑相通) on Tong's acupuncture. We classified the frequently used Tong's acupuncture points according to the principle of the mutual communication between organ and bowel. Results & Conclusions : Considering the locations and indications of the most frequently used points among the 740 master Tong's acupuncture points, we could reach the following conclusions; 1. The chief virtues of 66 master Tong's acupuncture points could be explained by the principle of mutual communication between organ and bowel. 2. Among the relationships of mutual communication between organ and bowel, the most frequently applied relationship was relationship which applied to 16 master Tong's acupuncture points, and the , , , , and followed. 3. Considering the body regions, 13 out of 66 master Tong's acupuncture points which the relationship of mutual communication between organ and bowel was applied to, were located at the 1-1 region, and the same number at the U region, the others were at the 7-7, 3-3, 2-2, 4-4, 10-10, 6-6, 5-5 regions in the order of the number of the points, and none at the 9-9 region.

It is necessary to expand organ donations of the deceased, as more ethical problems are emerging from the increase in organ donations from the living. As the legal and ethical discussions on donation after circulatory death (DCD) as a field with the potential to expand such domestic organ donation are being held, the need for a social consensus is increasingly highlighted. Organ DCD refers to the donation of an organ from a patient whose spontaneous blood circulation has stopped due to cardiac death. In this study, we aimed to examine whether there are legal and ethical obstacles or medical uncertainties for expanding the practice of DCD. By law, death is recognized as cardiac death, and brain death is recognized as an exception for organ transplantation. Although circulatory death precedes brain death, this paper presents a discussion to begin the process of reaching an ethical and legal agreement on whether or not circulatory death can be recognized as death. Successful implementations of DCD, including Category III DCD, in other countries are currently being reviewed to introduce Category III DCD in Korea.

Dose monitoring in CT patients requires accurate dose estimation but most of the CT dose calculation tools are based on Caucasian computational phantoms. We established a library of organ dose conversion coefficients for Korean adults by using four Korean adult male and two female voxel phantoms combined with Monte Carlo simulation techniques. We calculated organ dose conversion coefficients for head, chest, abdomen and pelvis, and chest-abdomen-pelvis scans, and compared the results with the existing data calculated from Caucasian phantoms. We derived representative organ doses for Korean adults using Korean CT dose surveys combined with the dose conversion coefficients. The organ dose conversion coefficients from the Korean adult phantoms were slightly greater than those of the ICRP reference phantoms: up to 13% for the brain doses in head scans and up to 10% for the dose to the small intestine wall in abdominal scans. We derived Korean representative doses to major organs in head, chest, and AP scans using mean CTDI_vol values extracted from the Korean nationwide surveys conducted in 2008 and 2017. The Korean-specific organ dose conversion coefficients should be useful to readily estimate organ absorbed doses for Korean adult male and female patients undergoing CT scans.

The subfornical organ (SFO) represents neuroglial circumventricular organ structures bordering the anterior third cerebral ventricle. Owing to the absence of the blood-brain barrier, the cellular elements of subfornical organ can be reached by circulating messenger molecules transferring afferent information and provide a good coding model of chemical information processing in the body.(omitted)

The model of an isolated organ system has been developed to simulate the kinetic behavior of drug levels in an acting organ or site. The model is developed from basic considerations of drug distribution with hemodynamical and pharmacokinetical meanings. Model: It is considered a situation in which non-metabolic drug substance is injected into the arterial inflow of an isolated organ at constant rate. The volume of distribution and the concentration of drug in the venous outflow can be mathematically expressed as a function of time.

The purpose of this study was to recognition of organ donation of nursing students in convergence and integration time so was to investigate the relationship between consciousness of biomedical ethics and attitude in organ donation. The participant were 202 nursing students and data were collected from April until July of 2017. Findings showed that consciousness of biomedical ethics wes 2.98 and attitude in organ donation was 2.67, and brain death was lowest at 2.67. The relationship between two variables showed a positive correlation(r=.18, p<.01), and Affecting Factors of consciousness of biomedical ethics was attitude in organ donation, gender, experience of studying for biomedical ethics, and the explanatory power was 9.1%. This result that for promotion of recognition of organ donation, we propose to implementing nursing ethics education focused on brain death and attitude in organ donation.

This study presents comparison results between axial and spiral scanning in the head and chest region with 64 MDCT to evaluate organ doses in infants and toddlers, who are more radiosensitive to radiation than adults and rise in the number of CT examinations, during CT scanning. Organ doses were significantly lower in spiral scanning than axial scanning regardless of scanned regions. The average organ dose for the chest scan using pitch of 1.355 was found to be significantly higher(average -12.03%) than for the other two pitch settings(0.525 and 0.988) in the spiral scanning mode compared with the axial one. Organ doses in the spiral scanning mode were lower by average 20.54% than the axial scanning mode. The results of the study that evaluated organ doses with an anthropomorphic phantom will help to demonstrate the result values of Monte Carlo simulations and make a contribution to more accurate evaluations of organ doses in toddlers undergoing a CT examination.

The purpose of this study was to investigate the influence of Consciousness of biomedical ethics on Nursing professionalism on Attitudes of organ transplantation among nursing students. Data were collected among 202 nursing students in G,P city, from october 12 to 22, 2021. The collected data was analyzed a using t-test, One way ANOVA, Pearson's correlation coefficient and Stepwise multiple regression using SPSS 20.0 WIN program. The average score for Consciousness of biomedical ethics was 3.39±0.44, Nursing professionalism was 3.84±0.56 and Attitudes of organ transplantation was 3.67±0.25. Factors Influencing Attitudes of organ transplantation were Right to life of newborn, Euthanasia, Social recognition, Professionalism of nursing and Role of nursing service. These variables accounted for 52.4% of Attitudes of organ transplantation. Based on the outcome of this study, developing an education program related to organ transplantation to contribute to the activation of organ transplantation.

The Korea Institute of Radiological and Medical Sciences has started a radiation epidemiological study, titled "Korean Radiation Worker Study," to evaluate the health effects of occupational exposure to radiation. As a part of this study, we investigated the methodologies and results of reconstructing organ-specific absorbed doses based on personal dose equivalent, H_p(10), reported from 1984 to 2019 for 20,605 Korean radiation workers. For the organ dose reconstruction, representative exposure scenarios (i.e., radiation energy and exposure geometry) were first determined according to occupational groups, and dose coefficients for converting H_p(10) to organ absorbed doses were then appropriately taken based on the exposure scenarios. Individual annual doses and individual cumulative doses were reconstructed for 27 organs, and the highest values were observed in the thyroid doses (on average 0.77 mGy/y and 10.47 mGy, respectively). Mean values of individual cumulative absorbed doses for the red bone marrow, colon, and lungs were 7.83, 8.78, and 8.43 mSv, respectively. Most of the organ doses were maximum for industrial radiographers, followed by nuclear power plant workers, medical workers, and other facility workers. The organ dose database established in this study will be utilized for organ-specific risk estimation in the Korean Radiation Worker Study.
