Inferior vena cava (IVC) injuries can have fatal outcomes and are associated with high mortality rates. Patients with IVC injuries require multiple procedures, including prehospital care, surgical techniques, and postoperative care. We present the case of a 67-year-old woman who stabbed herself in the abdomen with a knife, resulting in an infrarenal IVC injury. We shortened the transfer time by transporting the patient using a helicopter and decided to perform direct-to-operating room resuscitation by a trauma physician in the helicopter. The patient underwent laparotomy with IVC ligation for damage control during the first operation. The second- and third-look operations, including previous suture removal, IVC reconstruction, and IVC thrombectomy, were performed by a trauma surgeon specializing in cardiovascular diseases. The patient was discharged without major complications on the 19th postoperative day with rivaroxaban as an anticoagulant medication. Computed tomography angiography at the outpatient clinic showed that thrombi in the IVC and both iliac veins had been completely removed. Patients with IVC injuries can be effectively treated using a trauma system that includes fast transportation by helicopter, damage control for rapid hemostasis, and expert treatment of IVC injuries.

The author Nakajima was involved in the field of disaster communications and emergency medical care as guest research scientist at the Fukushima Nuclear Accident Independent Investigation Commission established by the National Diet of Japan and reviewer of the Commission's report, and Kurokawa was the chairman of this Commission. Looking back over a decade, we are on the liability issue of bureaucrats and telecom operators, so it's becoming clear what was hidden at the time. The battery of NTT DoCoMo's mobile phone repeaters had a capacity of only about 24 hours, and communication failures increased after one day. The Government also failed to issue an announcement of "Vent from reactor" under the Telecommunications Act Article No. 129. This mistake lost the opportunity to use the third-party telecommunications (e.g. taxi radios). Furthermore, as a result of LASCOM (telecommunications satellite network for local governments via GEO) and a variety of unexpected communication failures, the evacuation order "Escape!" could not be notified to the general public well. As a result, the general public was exposed to unnecessary radiation exposure. Such bureaucratic slow action in emergencies is common in the response to the 2020 coronavirus.

Purpose: The purpose of this study was to identify nursing service costs associated with all health care costs incurred by the institution. Methods: This study was an empirical case study research in which the nursing cost was separated from total medical cost. The nursing cost index was calculated through a cost allocation method after summarizing costs for personnel, raw materials and administration of each department in one public hospital. The 2014 budget plan, published in 'Public Hospitals Alert', was used as data and the data were analyzed using the Microsoft Office EXCEL 2013 program. Results: When comparing total medical costs and nursing costs, the nursing cost were 27.14% of the total medical cost. The nursing cost per nurse per hour was calculated as \29,128 The nursing cost per inpatient per day was calculated as \157,970, and the administration cost per patient was calculated as \133,710. Conclusion: The results of the research present the process of cost allocation of specific cost elements in the hospital and evidence for administrative costs which in the past have been only vaguely formulated. These are the significant implications of this study.

The changes in korean economic environment, from quantitative to qualitative growth of economy, go with making desperate efforts, that is, companies have put through many technical improvements, quality control, improvement of service, and so forth. Enterprises cut the number of employees through labor-management adjustment, so that a shortage of labor caused. An increase in intension of labor brought about growing the proportion of occupational diseases which is musculoskeletal diseases. Because of a rapid change in society and a change in our circumstances, we have many difficulties in examine a business disease closely. In support corroboration of relevance on admission of business, a criterion for dudging afford a basis for a causal relationship of medical science, take the state of working conditions into consideration, and at the same time, give a adaptable decision based on the purpose and point of "The Labor Standard Law" as well as "The Law about Industrial Accident Compensation insurance". In conclusion, it is necessary for the dental hygienists 10 reduce the on-duty hours a day, to make good postures in working, and to remove the stressful conditions in order to reduce the incidence of the lumbago. Good working postures, appropriate rest time, and early detection, care and education of the lumbago could be recommended for the dental hygienists.

This study evaluated the validity and reliability of applying a newly developed dish-based, semi-quantitative food frequency questionnaire (FFQ) for Korean diet and cancer research. The subjects in the present study were 288 Korean adults over 30 years of age who had completed two FFQs and four 3-day diet records (DRs) from May 2008 to February 2009. Student's t-tests, Chi-square tests, and Spearman's rank correlation coefficients were used to estimate and compare intakes from different dietary assessment tools. Agreement in quintiles was calculated to validate agreement between the results of the second FFQ (FFQ-2) conducted in February 2009 and the DRs. Median Spearman's correlation coefficients between the intake of nutrients and foods assessed by the FFQ-1 and FFQ-2 were 0.59 and 0.57, respectively, and the coefficients between the intake of nutrients and foods assessed by the FFQ-2 and the DRs were 0.31 and 0.29, respectively. The quintile classifications of same or adjacent quintile for intake of nutrients and foods were 64% and 65%, respectively. Misclassification into opposite quintiles occurred in less than 5% for all dietary factors. Thus this newly-developed, Korean dish-based FFQ demonstrated moderate correspondence with the four 3-day DRs. Its reliability and validity are comparable to those reported in other studies.

Objectives: Regional disparities in cardiovascular care in Korea have led to uneven patient outcomes. Despite the growing need for and access to procedures, few studies have linked regional service availability to mortality rates. This study analyzed regional variation in the utilization of major cardiovascular procedures and their associations with short-term mortality to provide better evidence regarding the relationship between healthcare resource distribution and patient survival. Methods: A cross-sectional study was conducted using nationwide claims data for patients who underwent coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), stent insertion, or aortic aneurysm resection in 2022. Regional variation was assessed by the relevance index (RI). The associations between the regional RI and 30-day mortality were analyzed. Results: The RI was lowest for aortic aneurysm resection (mean, 26.2; standard deviation, 26.1), indicating the most uneven regional distribution among the surgical procedures. Patients undergoing this procedure in regions with higher RIs showed significantly lower 30-day mortality (adjusted odds ratio [aOR], 0.73; 95% confidence interval, 0.55 to 0.96; p=0.026) versus those with lower RIs. This suggests that cardiovascular surgery regional availability, as measured by RI, has an impact on mortality rates for certain complex surgical procedures. The RI was not associated with significant mortality differences for more widely available procedures like CABG (aOR, 0.96), PCI (aOR, 1.00), or stent insertion (aOR, 0.91). Conclusions: Significant regional variation and underutilization of cardiovascular surgery were found, with reduced access linked to worse mortality for complex procedures. Disparities should be addressed through collaboration among hospitals and policy efforts to improve outcomes.

The aim of the present study is to obtain ecological data necessary for increasing the survival rate and effective individual management of fox cubs by analyzing the behavioral pattern during the lactation period. The subjects of the present study were baby foxes born in 2013 and taken care of at the species restoration technology institute, Korea National Park Service. Our analysis on the lactation of fox cubs and their appearance pattern outside the burrow revealed that the frequency and duration of lactation decreased with the growth of the cubs, whereas the frequency of the cubs venturing outside the den, activity time, and distance ventured increased. By the $30^{th}$ day after birth, in particular, the lactation behavior of the vixens largely decreased, and the activity of the cubs outside the den increased accordingly. Thus, for future management of the propagation of fox individuals for securing the original breed, it is necessary to increase the living food source. In addition, while capturing foxes for individual marking of cubs born in the wild, it is desirable to capture cubs older than 30 days not only for easy capture but also to minimize negative influence on the growth of the cub.

Objective: The purpose of this study was to investigate the effects of distribution justice, procedural justice, and interactional justice which are the sub-factors of organizational justice on organizational commitment and turnover intention, so as to enhance the quality of childcare and identify the importance of organizational justice. Methods: For the study, the data were collected by measuring the organizational justice, organizational commitment, and turnover intention of 251 teachers working in home day care centers in Busan, Ulsan, and Gyeongnam, and then Pearson's product moment correlation coefficient and regression analysis (stepwise) were conducted. Results: The results are as follows. First, organizational commitment was significantly different in the age in terms of the general background of daily care teachers, as well as the period of service of their current organization, and the turnover intention showed a significant correlation with their salary. Second, the sub-factors of organizational justice and organizational commitment were positively correlated, but turnover intention was negatively correlated. Among them, in terms of organizational commitment, procedural justice and turnover intention were highly correlated with distribution justice. Third, the relative impact of the sub-factors of organizational justice on organizational commitment was high in procedural justice and distribution justice. The relative influence on turnover intention was high in distribution justice and interactional justice. Conclusion/Implications: Therefore, the results of this study indicate that organizational justice is a influential variable on organizational commitment and turnover intention, and suggest that it needs to make efforts to strengthen organizational justice for the operation of home daycare centers.

Objectives: This study was conducted to analyze health behavior and utilization of university health clinics by college and university students. Methods: There are 376 colleges and universities in Korea as of May 2007. Of them 243 (69.6%) run health clinics in their campuses. Twenty of them were selected and 1,754 students were surveyed by using self reporting questionnaires. The data collected were analyzed by SPSS ver. 12.0. Results: Out of 1,754 students 56.5% were in good health. Of the subjects 15.6% were cigarette smokers, 30% were non drinkers, 20.8% exercise regularly, 53.7% sleep for seven to eight hours a day, 48% had proper body weight (BMI) 20-25) and 20% had physical examination in the past two years. The scores of health practices were higher in male students than female students (P 0.05). Perception rates of university clinics were higher in female students than male students. (P 0.01). Many students have intention to use the clinics (P 0.01). On health promotion program 35.2% of the subjects used clinics for emergency service, 32.8% participated in drinking control program, 32.8% in smoking cessation program, 20.4% in immunization program and 19.2% in regular health screening program. Conclusions: Comprehensive data for health behavior and need of health promotion services by the students should be collected regularly in order to meet the needs of students and faculty members in higher education institutes. The university authorities should pay more attention on the activities of health clinics in order to promote health of the students.
