Purpose: Dyslipidemia was a known risk factor for cardiovascular disease and was a leading cause of mortality in worldwide. This study aimed to determine the factors associated with prevalence and medication treatment of dyslipidemia in Korean adult population. Methods: In this study, based on the criteria set by the Korean Society of Lipidology and Atherosclerosis, the factors associated with prevalence and medication treatment of dyslipidemia was evaluated in a population of 12,506 people ($age{\geq}20$), who participated in the Korean National Health and Nutrition Examination Survey (2013-2015). The findings were tested by using multivariate logistic regression. Results: Dyslipidemia prevalence rate was 36.5%. Among populations with dyslipidemia, 17.5% were treated with lipid-lowering drugs. In the multivariate logistic regression model, male, increase in age, lower education level, non-drinker, current smoking, less physical activity, increase of body mass index, hypertension, and diabetes were associated with an increased odd of dyslipidemia. Female, increase in age, higher income, excess fat intake, hypertension, diabetes, myocardial infarction, and angina were associated with an increased odd of medication treat. Conclusion: The results of this study could be used to screen patients at the high risk for dyslipidemia or to predict medication adherence.

According to the results of related studies, one of the typical factors related to procedure related human errors is the complexity of procedures. This means that comparing the change of the operators' behavior with respect to the complexity of procedures may be meaningful in clarifying the reasons for the operators' non-compliance behavior. In this study, to obtain data related to the operators' non-compliance behavior, emergency training records were collected using a full scope simulator. And three types of the operators' behavior (such as strict adherence, skipping redundant actions and modifying action sequences) observed from the collected emergency training records were compared with the complexity of the procedural steps. As the results, two remarkable relationships are obtained. They are: 1) the operators seem to frequently adopt non-compliance behavior to conduct the procedural steps that have an intermediate procedural complexity, 2) the operators seems to accommodate their non-compliance behavior to the complexity of the procedural steps. Therefore, it is expected that these relationships can be used as meaningful clues not only to scrutinize the reason for non-compliance behavior but also to suggest appropriate remedies for the reduction of non-compliance behavior that can result in procedure related human error.

Significant advances in the diagnosis and medical care of children with chronic kidney disease (CKD) are major reasons for the better survival rates of children and adolescents with CKD than the survival rates reported in previous decades. These patients are reaching adulthood, and therefore require a transition to adult medical care. This transition phase is well-recognized to be associated with considerably increased morbidities and medical problems, such as non-adherence, graft loss after transplantation, and loss to follow-up. Low adherence increases morbidity and medical complications and contributes to poorer qualities of life and an overuse of the health care system. However, these tragic outcomes may be avoidable through a structured and well-defined transition program. In the last decade, there has been increasing interest to resolve these medical and psychological problems that occur during the transfer of young adult patients from pediatric to adult renal units. The aims of a successful transition from pediatric to adult medical care include enhancing the individual development of better health-competence and stabilizing, or even improving, the state of health. This review will focus on various aspects of the transition phase of adolescents who have CKD or who underwent kidney transplantation from pediatric to adult nephrology care.

Objectives : Treatment for bipolar disorder is often complicated by various clinical situations. We undertook a survey of expert opinions to facilitate clinical decisions in special situations such as weight gain, metabolic syndrome, hyperprolactinemia, genetic counseling, and treatment adherence. Methods : A written survey that asked treatment strategies related to safety and tolerability, was prepared focused on weight gain, antipsychotic related hyperprolactinemia, lamotrigine related skin rash, treatment non-adherence and genetic counseling. Sixty-one experts of the review committee completed the survey. Results : In the case of weight gain related to medications, experts preferred exercise and education for diet-control. First chosen medications were lamotrigine, aripiprazole and ziprasidone. Recommendations based on expert survey results for treatment of bipolar patients in other special situations are outlined. Conclusion : With limitation of expert opinions, authors hope that results of this study provide valuable information to make clinical decisions about treatment of bipolar disorder in complicated situations.

The sealing robot must be able to calculate the slope of a contact surface for complete adherence of the sealing on different concrete shapes. After the slope is obtained, the robot will track on the surface of the concrete, but this process contains an error in the actual purpose of the force command. The reason this a phenomenon occurs, the non-linearity of the contact surface and the end-effector, is due to parasitic coupling. Errors like make it difficult to measure accurately the respective factors. Therefore, it is regarded as a disturbance that occurs when it follows the work surface it. In this paper, we selected the friction coefficient of the surface as a control factor and designed a compensator to reduce effects of disturbance. Finally, in view of the non-linearity of the end-effector of a robot to contact surfaces directly, we propose a robust force tracking controller in the finite range for managing disturbances that occur during the sealing.

Hypertension is among the most common and important risk factors for stroke, heart attack, and heart failure which is considered to be the leading cause of death in Korea. The prevalence rate of hypertension in Korea is 27.9%, according to the 2006 Korea National Health and Nutrition Survey. Since non-pharmacologic nutrition education is recommended as the first step in the management of hypertension, evaluation of nutrition program is needed to form strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) for reducing the salt intake, at a public health center located in Gyunggi-province. The HNEP was offered for 16 weeks from May to September in 2007. Nutrition education activities included cooking classes, food preparation demonstrations, physical fitness programs, salty taste preference test sessions, games, case-study presentations, planning and evaluation of menus, etc. Forty patients participated fully in the program which had 47 female enrollees. Data about nutrient intake (24-hour recall), nutrition knowledge, food behavior were collected before (baseline) and after the program. Changes after program completion indicated the following: 1) diastolic blood pressure was decreased (p < 0.05), 2) sodium (salt) intake was also decreased (p < 0.01), especially baseline high salt intake group, 3) nutrition knowledge was improved (p<0.001), 4) dietary behaviors for maintaining a low salt diet was improved (p < 0.001), 5) participants preferred cooking class from nutrition education methods. As a conclusion, it appears that a nutrition education program for hypertensive female elderly for reducing the salt intake might effectively decrease blood pressure and salt intake. It also improves nutrition knowledge, dietary behavior, and finally adherence to a recommendable low-sodium diet.

Swarming has proven to be a good in vitro model for bacterial surface adherence and colonization, and the swarming differentiation of a bacterium has been shown to be coupled with changes in the expression of virulence factors associated with its invasiveness, particularly in the early stages of infection. In this study, we attempted to determine whether the expression of vvhA, which encodes for hemolysin/cytolysin (VvhA), is either upregulated or downregulated during the swarming differentiation of V. vulnificus. The insertional inactivation of vvhA itself exerted no detectable effect on the expression of V. vulnificus swarming motility. However, in our lacZ-fused vvhA transcriptional reporter assay, vvhA expression decreased in swarming V. vulnificus as compared to non-swarming or planktonic V. vulnificus. The reduced expression of vvhA in swarming V. vulnificus increased as a result of the deletional inactivation of luxS, a gene associated with quorum sensing. These results show that vvhA expression in swarming V. vulnificus is downregulated via the activity of the LuxS quorum-sensing system, suggesting that VvhA performs no essential role in the invasiveness of V. vulnificus via the adherence to and colonization on the body surfaces required in the early stages of the infection. However, VvhA may playa significant role in the pathophysiological deterioration occurring after swarming V. vulnificus is differentiated into planktonic V. vulnificus.

Homeroom teachers are not usually nutrition professionals, but they spend a lot of time with students in elementary school classrooms. This study was conducted to determine the association of homeroom teachers' nutrition education with the dietary habits of their classroom children. The subjects were 131 homeroom teachers and their 1,102 children from 17 elementary schools in Gyeonggi, Korea. Self-administered questionnaires to collect information on dietary habits were conducted in December 2016. The dietary habits were determined with the adherences to the Dietary Guidelines for Adults and Children, respectively, by coding the better diet life with a higher score. The significances between groups according to teachers' implementation of nutrition education (106 implemented, 25 not implemented) were analyzed by using SPSS at P<0.05. Implementing nutrition education was not associated with the dietary habits of teachers themselves, but their students. Therefore, the students of teachers who implemented nutrition education had significantly higher adherence to 8 items out of 19 items (P<0.05, P<0.01). More of the students considered themselves as non-picky eaters (P<0.05), tried to eat all the foods served at school lunch even when it contained unwanted ingredients (P<0.01), and agreed on the need of nutrition education (P<0.01), as compared to their counterparts. Conclusively, this study suggests that nutrition education delivered by homeroom teachers may be associated with more desirable dietary habits of students, even though homeroom teachers are not nutrition professionals. Therefore, efforts should be undertaken to develop and provide proper contents for homeroom teachers to use in nutrition education for elementary students.

Objectives: This study investigated the impact of socioeconomic factors and sexual orientation-related attributes on the rates of coronavirus disease 2019 (COVID-19) vaccination and infection among men who have sex with men (MSM). Methods: A web-based survey, supported by the National Research Foundation of Korea, was conducted among paying members of the leading online portal for the lesbian, gay, bisexual, transgender, or queer and questioning (LGBTQ+) community in Korea. The study participants were MSM living in Korea (n=942). COVID-19 vaccination and infection were considered dependent variables, while sexual orientation-related characteristics and adherence to non-pharmacological intervention (NPI) practices served as primary independent variables. To ensure analytical precision, nested logistic regression analyses were employed. These were further refined by dividing respondents into 4 categories based on sexual orientation and disclosure (or "coming-out") status. Results: Among MSM, no definitive association was found between COVID-19 vaccination status and factors such as socioeconomic or sexual orientation-related attributes (with the latter including human immunodeficiency virus [HIV] status, sexual orientation, and disclosure experience). However, key determinants influencing COVID-19 infection were identified. Notably, people living with HIV (PLWH) exhibited a statistically significant predisposition towards COVID-19 infection. Furthermore, greater adherence to NPI practices among MSM corresponded to a lower likelihood of COVID-19 infection. Conclusions: This study underscores the high susceptibility to COVID-19 among PLWH within the LGBTQ+ community relative to their healthy MSM counterparts. Consequently, it is crucial to advocate for tailored preventive strategies, including robust NPIs, to protect these at-risk groups. Such measures are essential in reducing the disparities that may emerge in a post-COVID-19 environment.
