  • This study conducted to provide the evidence to prevent and promote Metabolic Syndrome by figuring out the relationship between diagnostic indicators and health behavior of participants with Metabolic Syndrome. The subject included 633 participants who visited to university medical center or public health center in Daejeon from July 2017 to July 2018 for regular check-up. The data were analyzed using independent t-test, ANOVA, Scheffe test, Pearson's correlation coefficients by SPSS/WIN 22.0 program. As a result, 633 participants showed the differences in health behaviors according to age, religion, level of education, and the number of diagnostic indicators. By types of metabolic syndrome based on "hyperglycemia", there was a difference in stress management between groups. Moreover, in the group with hyperglycemia, hyperlipidemia was associated with stress management among health behaviors. Therefore, it is necessary to provide an interventional program that include these factors to improve Metabolic Syndrome.

  • Statistics of aviation accident in Korea show that safety level of training flights is high. However, more than 80% of aviation accidents happen owing to human factors. And because most reasons of them are concerned with pilot error, it is very important for student pilots who will transport a lot of passengers to develop the knowledge of safety and abilities of risk management for preventing accidents. In this study, in order to investigate the Human Factors which affect safety in training student pilots for flight, verified the correlationbetween experiences of accident, the differences according to the experience level of training flight and the differences between college student pilots and ordinary student pilots on the basis of human factors that composes the SHELL models. For the study, Using SPSS 17.0, conducted Correlation Analysis, Analysis of Variance(ANOVA) and t-test. To sum up the result of this study, student pilot's ability and equipment in the cockpit are the important factors for safety when pilots are training flight. Also the analysis of the differences between human factors according to the characters of student pilots' groups shows that college student pilots are affected by immanent factors and organizational cultures. So far, there haven't been any accidents which is related with human casualties when training at the ATO(Approved Training Organization). But accidents can occur at any time and anywhere. Especially the human factors which comprises most of aviation accident have a wide reach and are impossible to be eliminated, therefore, it is best to minimize them. Because ATO is the starting point to lead the aviation industry of Korea, we will have to be aware of problems and improve education/training of human factors.

  • BACKGROUND: Pesticides concentration was monitored in 50 agricultural lakes, and ecological risk for aquatic organism was assessed using risk quotient (RQ) and probabilistic methods. METHODS AND RESULTS: Pesticides concentrations detected in 50 agricultural lakes during peak season (June and September) were in the range of 0.170.99μg/L. The RQ for algae and the other species was estimated to be 0.25 and below 0.01, indicating medium risk and no risk. Oxadiazon predominantly contributed to RQ value of 99% for algae, fishes, and amphibians. In terms of hazardous concentration at 5% of species (HC5), ecological risk quotients (ERQ) for oxadiazon ranged from 0.18~0.33, showing a medium risk level. Overall, the concentrations of pesticides were much lower than HC5), value. Probability of combined ecological risk for pesticides ranged from 1.82% to 2.41%. CONCLUSION(s): Combined ecological risk probability did not exceed the acceptable level of 5%, indicating no ecological risk for selected aquatic species. This study suggests that regular ecological risk assessment (ERA) will be required to protect and manage an agricultural lake. Not only ERA at screening level by comparing exposure with toxic effects for aquatic species also advanced ERA technique considering species in indigenous to Korea, chronic toxicity, pulse dose, fate, and environmental factors should be required.

  • Purpose: Hospital readmissions have recently increased due to early hospital discharge and increased trends in breast-feeding. Neonatal hyperbilirubinemia can lead to fatal permanent neurological sequelae without appropriate management. Early detection and intervention are critical. We evaluated the clinical features, risk factors, and brain MRI findings of Korean newborns with idiopathic nonhemolytic hyperbilirubinemia to determine the optimal management policy. Methods: A retrospective review of the medical records of 79 newborns with idiopathic nonhemolytic hyperbilirubinemia was performed at the NICU of the Kyungpook National University Hospital from January 2006 to September 2009. All patients were 35 or more weeks of gestation, and their peak level of serum total bilirubin was more than 20 mg/dL. Results: The mean gestational age was 38+3±1+4 weeks, and the mean age on admission was 8.8±4.0 days. The mean body weight (3,105±479 g) was decreased by 2.8±6.4 percent compared to the mean birth weight (3,174±406 g). There were no statistically significant differences for the peak serum bilirubin level or the duration and effects of phototherapy between the patients with and without risk factors, which included: breastfeeding, cephalohematoma, subdural hemorrhage, and/or ABO incompatibility. Patients were grouped according to change of body weight. Group I consisted of patients that gained weight compared to birth weight, and group II of patients that lost weight compared to birth weight. There were significant differences in the peak serum total bilirubin level between the two groups. Thirty nine patients had brain MRI evaluation; 21 patients had bilateral symmetric signal intensity increases in the globus pallidus compared to adjacent corticospinal tract and putamen on T1-weighted images. Conclusion: Bilirubin encephalopathy is preventable with early screening and proper management. Parents require instruction on feeding practices and follow-up to prevent complications from idiopathic nonhemolytic hyperbilirubinemia.

  • Compared to other countries, cloud computing in Korea is not popular especially in the government sector. One of the reasons for the current not-fully-blossomed situation is partly by early investment in huge government datacenters under Korea's e-government initiative; let alone, there was no strong control tower as well as no enforcing law and ordinances for driving such cloud computing initiative. However, in 2015 March 'Cloud Computing and Privacy Security Act' (hereinafter, Cloud Act) had been passed in the Parliament and from September 2015 Cloud Act was deployed in Korea. In U.S., FedRAMP (Federal Risk Assessment and Management Program) along with Obama Adminstration's 'Cloud First' strategy for U.S. federal institutions is the key momentum for federal cloud computing adoption. In 2015 January, U.S. Congressional Research Service (CRS) has published an extensive monitoring report for cloud computing in U.S. federal institutions. The CRS report which monitored U.S. government cloud computing implementation is indeed a good guideline for Korean government cloud computing services. For this reason, the purpose of the study is to (1) identify important aspects of the enacted Korean Cloud Act, (2) describe recent U.S. federal government cloud computing status, (3) suggest strategy and key strategy factors for facilitating cloud adoption in public organizations reflecting SDLC strategy, wherein.

  • This study was conducted between October 1, 1998, and December 31, 1998, in order to provide basic data to develop better self-management educational programs for systemic lupus erythematosus (lupus) patients. In the study, the extent of each patients knowledge on the disease and their learning needs about it were examined for 100 lupus inpatients and outpatients at the Kangnam St. Marys Hospital. Data were collected by using questionnaires to those patients. Frequencies, percentage, average, standard deviation, t-test, ANOVA, and Duncans multiple range test were examined through the SAS program. The result of study follows : 1) The average score of patients knowledge on the disease was 15.7 (range, 7-20; standard deviation, 2.74). Subjects scored higher as far as the extent of their knowledge in the following categories : management of daily life, diet, characteristics of the disease, risk factors, and medication. Two categories shared the highest percentage of correct answers : 99% of subjects correctly identified that fatigue and stress aggravate symptoms of lupus and symptoms of lupus vary among individuals in range and type. However, when subjects were asked if patients should get a regular examination by an ophthalmologist every 4-6 months while they are on medication to treat rashes, lupus can be completely cured, and contraceptives that include a female hormone (estrogen) are good as contraceptive methods, the percentages of correct answers were low (32%, 31%, and 20%, respectively). In terms of subjects knowledge about the disease by their general characteristics, single subjects had more knowledge about the disease than married subjects did (t=2.14, p=0.0353). The extent of knowledge also varied by monthly income (F=4.96. p=0.0097). Those with more formal education had more knowledge about lupus than those who had less formation education did (t=2.95, 0.0039). Additionally, those who were satisfied with their education about the disease had better knowledge about it than those who were dissatisfied with their education did (t=2.71, p=0.0090). 2) The extent to which lupus patients wanted to be educated about the disease was, on average, 64.5 (range, 46-75; standard deviation, 7.91). Areas for which patients requested education are listed here in order : risk factors, sexual lives and patients associations. Patients who had been hospitalized demonstrated wanting more education than those who had not been did(t=3.73, p=0.0003). The extent to which they wanted the information was different by the number of educational sessions they had (F=3.98, p=0.0249). In conclusion, the results above would be considered when the education programme is planned for SLE patients.

  • A 10-year-old 4-kg spayed female Chihuahua with severe congestive heart failure was referred for surgical treatment. Through several examinations, the dog was diagnosed as severe mitral regurgitation (MR) and moderate TR. Because of the poor prognosis associated with continuation of medical management, surgical repair of the mitral valve was considered as the treatment option for the dog. The mitral valve repair was performed undergoing cardio pulmonary bypass (CPB) circuit. However after mitral repair, the dog was died without recovery from anesthesia. Many risk factors associated with failure of cardiac surgery are included CPB management, hypothermia, organ dysfunction, hemorrhage, hypotension, electrolyte & acid base imbalance, and infection. Although the dog is died from the operation, it is an important to reveal the factors of failure in veterinary clinic. From the case report, causes of failure of mitral valve repair can be considered from the failure of oxygenation and gas exchange by hypothermia and serious hypotension with low heart rate by low cardiac output syndrome (LCOS). Through the several considerations from this case, it is known that coming cardiac surgery for mitral valve repair is required to be more careful for successful operation. Further it can be brought to increase success rate in further operation.

  • This study was conducted to understand the research trends and central concepts of middle-aged women' health in Korea. For the analysis of this study, target papers published from 2012 to 2021 were collected by entering the keywords of 'middle-aged woman' or 'menopausal woman'. 1,116 papers were used for analysis. The co-occurrence network of key words was developed and analyzed, and the research trends were analyzed through topic modeling of the LSD by dividing it into five-year units (2012-2016, 2017-2021), and visualized word cloud and sociogram were used. The keywords that appeared the most during the last 10 years were obesity, depression, body composition, stress, and menopause symptom. Five topics analyzed in the thesis data for 5 years from 2012 to 2016 were 'postmenopausal self-efficacy and satisfaction enhancement strategy', 'exercise to manage obesity and risk factors', 'intervention for obesity and stress', 'promotion of happiness and life management' and 'menopausal depression and quality of life' were confirmed. Five topics of research conducted for the next five years (2017-2021) were 'menopausal depression and quality of life', 'management of obesity and cardiovascular risk factors', 'life experience as a middle-aged woman', and 'life satisfaction and psychological well-being' and 'menopausal symptom relief strategy'. Through the results, the trend of research topics related to middle-aged women's health over the past 10 years have been identified, and research on health of middle-aged women that reflects the trend of the future should be continued.

  • Background: This study aimed to establish a strategy to improve the poor working environment and working conditions among long-term healthcare workers in Korea. Methods: A total of 600 questionnaires with which long-term health care workers participated in the targeted base areas of each city and province nationwide were distributed directly and 525 responses were collected and 506 responses were analyzed. Surveys, on-site field visits, and in-depth interviews were also conducted to understand the working environment as well as conditions and establish a strategy for improving the working environment among long-term healthcare workers to understand the demands of working conditions and working conditions. Results: Korean long-term care workers firstly and mostly enumerated their risk factors for ill-health when lifting or moving elderly recipients directly by hand (69.9%), followed by increased physical workload with old beds, tools, and facilities (42.3%) in the workplaces, shortage of manpower (32%), and source of infection (30%). To improve the working environment as well as conditions, Korean long-term care workers considered improving low-wage structures, ergonomic improvements to solve excessive physical loads, and increasing various bonus payments as well as implementing the salary system, positive social awareness, and increasing resting time. Of 506 responses, 92.3% replied that the long-term care insurance system for the elderly should be developed to expand publicization at the national level. Conclusion: This study proposes to improve the low-wage structure of Korean long-term care workers, automation and improvement of facilities, equipment, and tools to eliminate excessive physical loads (beneficiary elderly lifting), and reduction of night labor.

  • Platform contrasts with traditional industry in terms of innovativeness as it is rapidly developing with information technology. To redeem preceding researches which have separately focused on either platform acceptance based on technology acceptance model or resistance factors against platform's innovation, this study applied dual factor theory to check the simultaneous influence of enablers and inhibitors on resistance. This study chose purchasers of online used trading platform as a subject of study since it contrasts with other platforms in many characteristics. Based on preceding studies, the moderating effects of their past purchase numbers on the relations between resistance and use intention were also checked. The findings reveal that economic benefit as an enabler had significant negative influence on the resistance, but social influence didn't have expected influence. In case of inhibitors, both perceived complexity and perceived risk had significant positive influence on the resistance. Though resistance had significant negative influence on the use intention, its influence was moderated into the positive direction as users' purchase number increased. Lastly, resistance had mediation effect between antecedent factors (economic benefit and perceived complexity) and use intention.
