Interventional cardiology procedures can involve relatively high radiation doses compared to conventional radiography. During CAG, CAG + PCI and PCI the same area is exposed to radiation for a long period. In this study, radiation exposure data of 421 examinations in Gyeongsang area were collected, and the DRLs and ADs in actual medical practice for three types of interventional cardiology procedures in Korea were established. In CAG 286 case, 75th percentile DRLs and ADs of the total DAP were 55.89 Gy·cm² and 37.47 Gy·cm² , respectively. In CAG + PCI 92 case, those values were 222.84 Gy·cm² and 117.51 Gy·cm² respectively. In PCI 43 case, those values were 198.73 Gy·cm² and 120.13 Gy·cm² respectively. In this study, for the first time, the diagnostic reference level of interventional cardiology procedures in Gyeongsang area were established. Using the diagnostic reference level of interventional cardiology procedures derived from this study, it will help to identify and improve the level of exposure dose in the region and country.

Purpose: The aim of this study was to identify core keywords and topic groups in the 'Diabetes mellitus and mobile applications' field of research for better understanding research trends in the past 20 years. Methods: This study was a text-mining and topic modeling study including four steps such as 'collecting abstracts', 'extracting and cleaning semantic morphemes', 'building a co-occurrence matrix', and 'analyzing network features and clustering topic groups'. Results: A total of 789 papers published between 2002 and 2021 were found in databases (Springer). Among them, 435 words were extracted from 118 articles selected according to the conditions: 'analyzed by text network analysis and topic modeling'. The core keywords were 'self-management', 'intervention', 'health', 'support', 'technique' and 'system'. Through the topic modeling analysis, four themes were derived: 'intervention', 'blood glucose level control', 'self-management' and 'mobile health'. The main topic of this study was 'self-management'. Conclusion: While more recent work has investigated mobile applications, the highest feature was related to self-management in the diabetes care and prevention. Nursing interventions utilizing mobile application are expected to not only effective and powerful glycemic control and self-management tools, but can be also used for patient-driven lifestyle modification.

Objective : This study aimed to investigate the importance, performance, and educational needs of sensory integration intervention competency for newly employed therapists who use sensory integration intervention. Methods : The general characteristics, importance, performance, and educational needs of sensory integration intervention competency were investigated for therapists with less than three years of experience in sensory integration intervention. Educational needs and rankings were identified through Borich needs analysis. Results : The competency cluster that newly employed therapists perceived as the most important but with the lowest performance level was "Expertise," and the demand of the "Expertise" competency cluster was also the highest in the analysis of educational needs. The difference in importance and performance in all sub-competencies was statistically significant. In the Borich needs analysis, the rank of educational needs was derived as follows: "Evaluation skill" (5.56), "Analysis skill" (5.50), and "Overall knowledge of occupational therapy" (5.47). Conclusion : It was found that the newly employed therapist using sensory integration intervention recognized professional competency as the most important, while also recognizing that their professional competency was low. Accordingly, education to enhance professional competency was most needed. This study presented basic data for the direction of education to strengthen competency in consideration of the educational needs of newly employed therapists.

Internalizing and externalizing behavior problems may be more common in children with disability families but rarely known is the magnitude of the problem and the risk factors compared to those in children with non-disability families. This study was undertaken to examine if socio-economic factors, parental health, and family functioning affect children's internalizing and externalizing behaviors differently between two comparison groups. The research literature on childhood behaviors was briefly reviewed. The data was derived from the Mental Health of Children and Young People in Great Britain, 2004. Regression analyses provide evidence that the family type, economic status, and income level are uniquely associated with an increased risks of internalizing or externalizing behavior problems in children with disability families, whereas sex, age, family size, parental health, and family functioning factors have similar impacts on the child's internalizing or externalizing variances between two groups. Intervention is desirable to address the concerns influencing internalizing and externalizing performances among children with disability or non-disability families.

This study sought to find a nursing intervention tool for enhancing elderly women's lives by investigating the causes and the meaning of their grief. Method: This research was derived from a phenomenological tool such as qualitative research design. The data collection took place from December of 2000 until April of 2001 Through systematic interviews and participatory observations of five elderly women attending C welfare center located in downtown Seoul the data was collected. Each interview lasted an hour and a half and was arranged five times. The analysis of this research was conducted using the Giorgi method. Results: \circled1 There was obvious physical and physiological decline caused by aging old; as well as there being spouse health problems, additional physical suffering, signs of senility, and insomnia, \circled2 Further grief was imposed by unpleasant memories of the spouse; infidelity, incapability, and even disregard of her own well-being, \circled3 Then there was pity for children; unfaithful children, uncertain futures of the children, and early death of a child, \circled4 Also, regrettable fate, painful daily acttrities, unreliable factors, bad circumstances, and feelings emptiness were reported, \circled5 Finally, anxiety for the future; ac sense of despair, loneliness, economic hardship, and the fear of imminent death increased grief levels. Conclusion: A variety of programs and social meetings for the elderly to overcome their physiological or psychological crisis should be substantially developed and supported by the government. In order to implement the social welfare for the elderly women, special consideration whether on the governmental level or the personal level, should be devoted to the elderly who live without any financial support or social concern.

The emergence of carbapenem resistance among Pseudomonas aeruginosa is an increasing problem in many parts of the world. In particular, metallo-$\beta$-lactamases (MBLs) and AmpC $\beta$lactamases are responsible for high-level resistance to carbapenem and cephalosporin. We studied the diversity and frequency of $\beta$-lactamases and characterized chromosomal AmpC $\beta$lactamase from carbapenem-resistant P. aeruginosa isolates. Sixty-one carbapenem-resistant P. aeruginosa isolates were collected from patients in a tertiary hospital in Daejeon, Korea, from January 2011 to June 2014. Minimum inhibitory concentrations (MICs) of four antimicrobial agents were determined using the agar-dilution method. Polymerase chain reaction and sequencing were used to identify the various $\beta$-lactamase genes, class 1 integrons, and chromosomally encoded and plasmid-mediated ampC genes. In addition, the epidemiological relationship was investigated by multilocus sequence typing. Among 61 carbapenem-resistant P. aeruginosa isolates, 25 isolates (41.0%) were MBL producers. Additionally, 30 isolates producing PDC (Pseudomonas-derived cephalosporinase)-2 were highly resistant to ceftazidime (MIC₅₀ = $256{\mu}g/ml$) and cefepime (MIC₅₀ = $256{\mu}g/ml$). Of all the PDC variants, 25 isolates harboring MBL genes showed high levels of cephalosporin and carbapenem resistance, whereas 36 isolates that did not harbor MBL genes revealed relatively low-level resistance (ceftazidime, p < 0.001; cefepime, p < 0.001; imipenem, p = 0.003; meropenem, p < 0.001). The coexistence of MBLs and AmpC $\beta$-lactamases suggests that these may be important contributing factors for cephalosporin and carbapenem resistance. Therefore, efficient detection and intervention to control drug resistance are necessary to prevent the emergence of P. aeruginosa possessing this combination of $\beta$-lactamases.

Objectives: The purpose of this study is to objectify the level of case management performance and the factors influencing performance, to improve the case management performance at the Korea Worker's Compensation & Welfare Service (KWCWS) on the basis of the recognition of the objective realities of case management by job coordinators at the KWCWS, to develop a model of case management fit for the KWCWS, and to provide a basis for establishing guidelines for standardized case management. Methods: A total of 156 questionnaires were distributed to job coordinators at the KWCWS's headquarters, six regional headquarters, and 55 branches. One hundred forty-one questionnaires were collected and 126 were analyzed statistically using SPSS 21.0. Factor analysis and reliability analysis were conducted to verify the validity and reliability of the main measurement items in the research model. Frequency analysis was conducted for general characteristics of survey subjects. Frequency analysis or descriptive statistics were conducted to identify the level of independent variables (case manager's individual variables, job variables, institutional and organizational variables). Dependent variables (case management performance) and the degree of correlation were analyzed through correlation analysis between research variables. Multiple regression analysis and hierarchical regression analysis were conducted to examine the effect of independent variables on case management performance. Results: The results of the study showed that the level of overall performance in the five stages of case management was ordinary, with an average level of 3.45 on a 5-point scale. Levels of performance by step were institutional approach and intake (3.69), assessment (3.63), goal setting and intervention planning (3.46), implementation of intervention plan (3.32), and evaluation and termination (3.20), in that order. The explanatory power of case management performance (overall) by case managers with the KWCWS was case manager's institutional and organizational variables, job variables, and individual variables, in that order. At each stage of case management, the explanatory power of a case manager's institutional and organizational variables was found to be the greatest. The model changes at each stage of case management assume similar aspects statistically. In hierarchical regression analysis, it was institutional support that had a significant effect on case management performance (overall), and institutional support had the greatest effect. The results of multiple regression analysis in which all variables are input simultaneously showed that institutional support and expertise as well as self-efficacy had a positive effect. However, case management work experience, expertise (technology), and autonomy were found to have a negative effect during the stage of case management performance. Conclusions: As a result of the study, it was confirmed that raising the case manager's expertise and support from the institution and organization are important factors to improve the level of case management performance. The research also derived practical ways of reinforcement of case manager capacity, institutional and organizational support, operation of rehabilitation-case management teams, and occupational health-related aspects.

The optimized derived intervention levels for animal products were evaluated based on cost-benefit analysis. From these results, the radionuclide concentrations in animal feedstuffs for use were derived. It was shown that radionuclide concentrations in animal feedstuffs for use depend strongly on animal products, radionuclides and feeding period (period from the starting time to be led with contaminated feedstuffs to production time of animal products). In case of feedstuffs contaminated with long-lived radionuclides ($^{l37}Cs,\;^{90}Sr$), the feedstuffs with lower contamination should be supplied to animals with increase of feeding period due to the bioaccumulation of radionuclides. While, in case of feedstuffs contaminated with short-lived radionuclides ($^{131}I$), the feeding of higher contaminated feedstuffs was possible with increase of feeding period due to radionuclide decay. It was shown that $^{137}Cs$ concentration in animal feedstuffs lot use was lower than $^{90}Sr$ concentration. It is primarily, due to the higher feed-animal product transfer factor of $^{137}Cs$.
