Purpose: We reviewed the cases of occupational diseases that occurred in healthcare workers from 2010 to 2019 and the cases of epidemiological investigations conducted by the Occupational Safety and Health Research Institute for them. Methods: In this study, gender, age, working period, occupational characteristics, and disease characteristics by occupation, which are general characteristics of healthcare workers approved for occupational diseases. In addition, 32 cases of epidemiological investigation of healthcare workers conducted by the Institute for Occupational Safety and Health for the past 10 years (2010~2019) were analyzed. Results: The gender, age, working period, occupational characteristics, and disease characteristics by occupation of medical workers recognized as occupational diseases were all statistically significant (p<.001). In the epidemiological investigation, ionizing radiation( 50.0%) and stress (33.3%) were recognized as disease-related factors, and even in cases of disapproval, ionizing radiation (60.0%) and shift work (25.5%) were designated as related factors. And it was statistically significant (p=.008). Conclusion: The current study identified the types of diseases, various causes, and general characteristics and occupational characteristics that occur frequently in healthcare workers. Therefore, if this study is used as basic information to set the priority and direction of disease prevention project for healthcare workers, it is judged that it will be helpful in preventing industrial accidents.

Objective: This study was performed to evaluate testicular sperm chromatin condensation using aniline blue-eosin (AB-E) staining and its effects on IVF-ET. Methods: Chromatin condensation was analyzed using AB-E staining in 27 cases of testicular sperm extraction. There were 19 cases of obstructive azoospermia (OA) and 8 cases of non-obstructive azoospermia (NOA) in IVF-ET. Mature sperm heads were stained red-pink whereas immature sperm heads were stained dark blue. The percentage of sperm chromatin condensation was calculated from the ratio of the number of red-pink sperm to the total number of sperm analyzed. Results: The overall percentages of chromatin condensation in OA and NOA were $31.1{\pm}11.2%$ and $26.3{\pm}14.4%$, respectively. The fertilization rate was significant higher in OA than NOA ($p$ <0.05); however, the rates of good embryos and clinical pregnancy did not show statistical differences. In OA and NOA, statistical differences were not observed in the rate of chromatin condensation, fertilization, good embryos, and clinical pregnancy between the pregnant group and non-pregnant group. Conclusion: Chromatin condensation is less stable than OA and showed a low fertilization rate in NOA. While there were no significant differences in chromatin condensation results between NOA and OA, we propose that a pattern of decreased chromatin condensation in NOA is one of the factors of low fertilization results requiring further study.

This study aimed to assess the mobility and thermal comfort of personal protective equipment (PPE) among female healthcare workers, taking into account wearers' physique and PPE protection levels. A total of 16 participants (age: 26.3 ± 8.3 y, height: 161.5 ± 7.3 cm, body weight: 57.1 ± 11.0 kg, BMI: 21.9 ± 3.6), representing diverse body types, underwent four PPE conditions: L (Low_Plastic gown ensemble), M (Medium_Tyvek 400), H (High_Tyvek 800J with Powered Air Purifying Respirator [PAPR]), and E (Extremely high_Tychem 2000 with PAPR, Bib apron, and Chemical-resistant gloves). The mobility protocol consisted of 10 different tasks in addition to donning and doffing. The 10 tasks were repeated twice at an air temperature of 24.3 ± 0.1℃, 59±4%RH. Findings revealed a disproportionate relationship between PPE protection and wearer discomfort. Significant differences in clothing microclimate and total sweat rate were observed between the lowest (L) and highest (E) protection levels (p < 0.01), while distinctions among medium levels were inconclusive. Subjective evaluations favored conditions H and L over M and E (p < 0.05), indicating reduced heat, and humidity, increased comfort, and lower exertion. Instances of mobility discomfort, specially in the small body type group, underscored the need for a suitable PPE size system for Korean adult female medical workers. Furthermore, enhancements in gloves, shoe cover, and PAPR hood designs are essential for improving ease of movement and preventing hindrance.

Objectives : This study aimed to investigate the attitude of healthcare consumers toward the East-West Collaborative Medical Practices(hereafter EWCMP). Method : The participants were 245 healthcare consumers who visited outpatient clinic of an university hospital, and attended at an emergency rescue educational program held by an emergency medical center, Busan. Data were collected by interviewing or self-reporting with questionnaires and analyzed with descriptive statistics and $X^2$ test with SPSS win 14.0. Results : 53.1 percent of 245 participants has heard, 13.9 percent has ever used, and 82.4 percent wanted to use EWCMP in the future. For participants who has used EWCMP, the decision to use it was made by themselves(58.8%), 26.5% of them was satisfied with EWCMP, and 79.4% showed the intention to introduce EWCMP to others. The use of EWCMP was significantly different by gender($X^2$=4.702, p=0.030) and having job or not($X^2$=14.305, p<0.001). Preferred type of EWCMP was to use both medical and Korean medical treatment at the same time(42.4%). Musculoskeletal disease(51.0%) and circulatory disease(51.0%) were expected to be the most effective when the EWCMP applied to them. Utilization of EWCMP was expected to be effective in disease treatment(88.2%), diagnosis(83.3%), and prevention(75.1%), and to increase medical cost(66.1%). Intention to use of EWCMP was not significantly different by demographic characteristics. Conclusion : Considering low proportion of utilization of and positive attitude toward the EWCMP among general populations, it is needed to introduce or advertise EWCMP to them.

The purpose of this study was to assess adequately equipped with convenience facilities for the disabled in 160 healthcare institutions in Jongno district, Seoul. Healthcare institutions were equipped an average of 3.7 facilities out of 10. General hospitals had an average of 5.0 facilities, which was higher than an average of 3.6 facilities for private clinics (p<0.05). Of 160 healthcare institutions, only 13 (8.1%) offered easy access to the outpatient setting from the entrance for wheelchair users, highlighting difficult wheelchair access within hospitals. To provide easy access to medical service for the disabled, more accessible designs need to be adopted as part of the effort to improve public facilities for the disabled. Also, universal designs could be applied for newly constructed roads, structures and transportation vehicles to maximize accessibility for the disabled. Increased accessibility for the disabled in the community will eventually increase the use of healthcare institutions.

Background: After the first case of coronavirus disease 2019 (COVID-19) in January 2020, Korea has experienced three waves in 2020. This study aimed to analyze changes in health care utilization according to the period of the 1st to 3rd waves of the COVID-19 pandemic. Methods: We analyzed 3,354,469,401 national health insurance claims from 59,104 medical facilities between 2017 and 2020. Observed-to-expected ratios (O:E ratio) with data from 2017 to 2019 as expected values and data from 2020 as observed values were obtained to analyze changes in medical utilization. T-test was used to test whether the difference of observed and expected values was statistically significant. Results: In 2020, the O:E ratio was 0.894, indicating a decrease in health care utilization overall during the pandemic. The O:E ratio of the 1st wave was 0.832, which was lower than those of the second (0.886) and third (0.873) waves. Health care utilization decreased relatively more among outpatient, women, children and adolescents, and health insurance patients. And health care utilization decreased more in small medical facilities and in Daegu and Gyeongbuk during the first wave. During the pandemic, the O:E ratios of respiratory diseases were 0.486-0.694, while chronic diseases and mental diseases were more than 1.0. Conclusion: Health care utilization decreased during the COVID-19 pandemic overall, and there were differences by COVID-19 waves, and by the characteristics of patients and medical facilities. It is necessary to understand the cause of changes in health care utilization in order to cope with the prolonged COVID-19 pandemic.

Objective: This study aimed to compare the clinical outcomes between in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in sibling oocytes. Additionally, we evaluated whether the implementation of split insemination contributed to an increase in the number of ICSI procedures. Methods: A total of 571 cycles in 555 couples undergoing split insemination cycles were included in this study. Among them, 512 cycles (89.7%) were a couple's first IVF cycle. The patients were under 40 years of age and at least 10 oocytes were retrieved in all cycles. Sibling oocytes were randomly allocated to IVF or ICSI. Results: Total fertilization failure was significantly more common in IVF cycles than in ICSI cycles (4.0% vs. 1.4%, p<0.05), but the low fertilization rate among retrieved oocytes (as defined by fertilization rates greater than 0% but < 30%) was significantly higher in ICSI cycles than in IVF cycles (17.2% vs. 11.4%, p<0.05). The fertilization rate of ICSI among injected oocytes was significantly higher than for IVF ($72.3%{\pm}24.3%$ vs. $59.2%{\pm}25.9%$, p<0.001), but the fertilization rate among retrieved oocytes was significantly higher in IVF than in ICSI ($59.2%{\pm}25.9%$ vs. $52.1%{\pm}22.5%$, p<0.001). Embryo quality before embryo transfer was not different between IVF and ICSI. Although the sperm parameters were not different between the first cycle and the second cycle, split insemination or ICSI was performed in 18 of the 95 cycles in which a second IVF cycle was performed. Conclusion: The clinical outcomes did not differ between IVF and ICSI in split insemination cycles. Split insemination can decrease the risk of total fertilization failure. However, unnecessary ICSI is carried out in most split insemination cycles and the use of split insemination might make ICSI more common.
