Background: According to the World Health Organization (WHO), 99 percent of the world’s population is exposed to air that exceeds WHO recommendations, with low- and middle-income countries being the most affected. The main causes of indoor air pollution include human activities such as fuel burning, cooking, cleaning, and smoking; housing characteristics such as walls, floors, ceilings, and furniture; ventilation; and outdoor air pollution. Aim : To assess PM1 and PM10 concentrations in 120 selected households in Ulaanbaatar. Materials and Methods : Indoor PM1 and PM10 concentrations were measured using Purple Air real-time sensors in randomly selected Ulaanbaatar households between October 2023 and January 2024. Supplementary data on factors affecting the PM2.5 concentration were collected via questionnaires. Each measurement was taken in 10-minute intervals, yielding 51,309 data for analysis. Results : PM1 concentrations were measured at 55.5±53.2 μg/m³ in gers, 54.9 ± 46.7 μg/m³ in houses, and 31.6±40.1 μg//m³ in apartments (p<0.001) and measuring PM10 concentrations were 110.6±108.6 μg/m³ in gers, 110.6±96.7 μg/m³ in houses, and 62.2±83.0 μg/m³ in apartments (p<0.001) When considering the concentration of PM1, PM10 by heating type, PM1 was 55.3±50.1 μg/m³ and PM10 was 110.6±103.0 μg/m³ in households with stoves and furnaces, and PM1 was 31.6±40.1 μg/m³ and PM10 was 62.2±83.0 μg/m³ in households connected to the central heating system (p<0.001). Regarding the months of measurement, the highest concentration was observed in December 2023, at 77.1±94.1 μg/m³. The highest concentrations for both PM₁ and PM₁₀ were recorded in January 2024, at PM₁: 64.8±55.1 μg/m³, PM₁₀: 131.4±116.0 μg/m³. Conclusion 1. Indoor PM10 concentrations in residential environments in Ulaanbaatar city were within the MNS4585:2016 Air Quality Standard, however, it was exceeded the WHO air quality guidelines, indicating an excessive risk of increasing morbidity and mortality among the population. 2. Indoor PM1 and PM10 concentrations in residential environments in Ulaanbaatar varies depending on location, type of housing, type of heating, and month of measurement.

Background: To effectively deliver healthcare services, it is necessary to strengthen and expand the education system for qualified biomedical equipment technicians and engineers. This should be combined with measures such as providing modern equipment to health facilities and making spare parts available. Internationally, there is a reference of one engineer responsible for 100 pieces of equipment. Additionally, one engineer is responsible for each major piece of equipment such as MRI, CT, positron emission tomography (PET SCAN), and angiography equipment. However, in our country, the standard is independent of the number of medical equipment. Although 4 universities nationwide train medical equipment engineers and technicians, they are unable to meet the growing market needs. Aim: To assess human resource needs for biomedical equipment specialists. Materials and Methods: We conducted the study using an analytical survey design. In the study, data were collected from a total of 272 engineers and technicians using a self-administered questionnaire that included years of work experience, post-graduate training, qualification level, and workload. The data were processed using SPSS Statistics 26 software, and the results were presented in figures, tables, and sentences. Results: Of the professionals surveyed, 72.4% were male, 95.6% were full-time employees, and 68.8% had a bachelor’s degree. However, the majority (90.4%) of the professionals did not have a professional degree. When asked about the availability of on-the-job and other training among the professionals 73.5% had not received any training at all. The level of training received by professionals did not depend on the organization they worked for. However, there was a statistically significant difference between the level of training received from foreign and manufacturer-sponsored organizations. The professionals surveyed had relatively little training since they started working. As the number of years of experience in their profession increased, the number of times they participated in manufacturer-sponsored training increased. However, the number of times they participated in domestic, foreign, or postgraduate training was not related to the number of years of experience. Conclusion Medical equipment engineers and technicians are working harder than international professionals. The lack of post-graduate training for healthcare professionals is a concern for the industry.

Background: According to the World Health Organization (WHO), 6.7 million people die annually due to air pollution caused by solid fuel use, with the majority of deaths resulting from respiratory diseases and cardiovascular conditions. In Mongolia, air pollution ranks as the fourth leading risk factor contributing to mortality, following hypertension, diabetes, and other major health risks. Although there have been numerous studies on outdoor air pollution in Mongolia, research linking indoor air pollution at the household level with the health status of residents remains limited. Aim: To compare indoor PM2.5 concentrations in households of Ulaanbaatar and Darkhan and examine their association with hypertension during the winter season. Materials and Methods: The study was conducted during November and December 2023, and January 2024, involving 240 households in Ulaanbaatar and Darkhan. Indoor PM2.5 concentrations were measured using Purple Air real-time sensors continuously for 24 hours over approximately one month. After measuring indoor air pollution, individuals aged 18–60 years living in the selected households were recruited based on specific inclusion criteria. Blood pressure was measured three times and the average value was recorded. Information on respiratory illnesses was collected through structured questionnaires. Statistical analysis was performed using STATA version 19.0. Results: A total of 241 households participated in the study, with 116 from Ulaanbaatar and 125 from Darkhan. Of the participants, 46.5% were male and 53.5% were female. In terms of housing type, 96 households (39.8%) lived in gers, 97 (40.2%) lived in stove-heated houses, and 48 (19.9%) lived in apartments. Among all participants, 66.0% (n=159) had hypertension and 34.0% (n=79) had normal blood pressure. Among participants aged over 40, 69.9–88.5% had hypertension, which is statistically significantly higher compared to younger individuals (p=0.0001). By body mass index, 75.3% (n=72) of overweight individuals and 78.4% (n=58) of obese participants had hypertension, showing a statistically significant difference compared to participants with normal weight (p=0.0001). The 24-hour average concentration of indoor PM2.5 was measured using the Purple Air device, and the levels in gers and stove-heated houses exceeded the limit set by the MNS 4585:2025 standard (37.5 µg/m³) Conclusion This study identified a relationship between environmental factors, such as air pollution and housing type, and the prevalence of hypertension. The indoor PM2.5 concentration in gers and stove-heated houses was above the standard limit, indicating a negative impact on the health of those residents. Furthermore, the high prevalence of hypertension among participants over the age of 40 and those who are overweight suggests a possible link to lifestyle and environmental conditions.

Background: Particulate matter with an aerodynamic diameter of 2.5 micrometers or smaller (PM2.5) penetrates deep into the alveoli through the respiratory tract and is characterized by its ability to induce oxidative stress, systemic inflammation, and vascular inflammation. Mongolia ranks among the countries with the highest levels of air pollution. In Ulaanbaatar, where more than half of the country’s population resides, wintertime PM2.5 concentrations often exceed 200 μg/m³, which is about eight times higher than the World Health Organization (WHO) guideline value. A study involving 1,200 adults in Ulaanbaatar showed that quality of life deteriorated sharply during periods of high air pollution, with effects more pronounced among individuals who already had impaired respiratory function. Aim: To examine the relationship between indoor household PM2.5 concentrations and lung function indicators among adults in Ulaanbaatar and Darkhan. Materials and Methods: This analytical cross-sectional study recruited adult participants from Ulaanbaatar and Darkhan through targeted sampling. Household air quality was measured using PurpleAir sensors, which were installed in participants’ homes for one month. After exposure measurement, lung function was assessed via spirometry. Statistical analyses were conducted using SPSS version 25.0. Results: A total of 236 participants were included: 114 (48.3%) from Ulaanbaatar and 122 (51.7%) from Darkhan. The sample consisted of 111 men (47.0%) and 125 women (53.0%). The mean indoor PM2.5 concentration was 66.24 μg/m³ (SD 44.87 μg/m³), ranging from a minimum of 7.79 μg/m³ to a maximum of 264.55 μg/m³. Stratification by housing type showed the highest PM2.5 levels in gers (82.34 μg/m³), followed by detached houses (67.34 μg/m³), while apartments had the lowest concentrations (32.24 μg/m³). Correlation analysis revealed statistically significant negative associations between PM2.5 levels and measures of expiratory function, including the FEV1/FVC ratio, peak expiratory flow (PEF), and mid-expiratory flow (FEF25–75). Reduced forced vital capacity (FVC) was observed in 9.4% of participants, reduced forced expiratory volume in one second (FEV1) in 15.3%, and a decreased FEV1/FVC ratio in 3.8%. Conclusion Indoor household PM2.5 concentrations were highest in gers, and expiratory flow-related lung function parameters showed significant negative associations with particulate exposure. This suggests that indoor PM2.5 primarily affects airflow limitation rather than overall lung volumes in this population.

Experimental group -2 and comparison group for dry cough caused by citric acid 17%, it affects the cough receptors in the mucous membrane of the respiratory tract and relaxes the bronchial muscles (A and C fiber).

Abstract: Burn injury causes considerable incidence of disability, increase of hospitalization and rehabilitation. It is a crucial factor of morbidity and mortality, throughout the world, especially in the developing countries. Burn wound healing is a complex process including inflammation, granulation, and regeneration of the skin tissue. There are many animal and mineral derived agents applied for burn wounds treatment. For example, minerals and animal yellow marrow are applied as standard topical therapy in healing of burn wounds in the history. Specially, Mongolian camel’s (Camelus Bactrianus) yellow marrow and cinders have been used the healing effect standard topical antimicrobial for burn wounds for several centuries. The present study aimed to determine the healing effect of “CIBO” ointment with animal and mineral raw materials on third -degree burn wound in rats. Introduction: In our study, we selected an ointment containing a combination of yellow marrow and cinder. In ancient times, Mongolians used camel yellow marrow to relieve joint pain, spread people who had been bedridden for a long time due to the disease, and to prevent caries, and to use it on open wounds. In traditional medicine, cinder has been used as a mineral raw material and has been used to treat frostbite and burns. Material and methods: In the Vivar Department of the Pharmacology Sector of the Drug research institute, 18 Wistar white rats weighing 182-220 g fed in one environment for (12 hours a day/12 hour a night) were randomly selected and divided into the following groups. These are: negative control, Group 1 “Yellow marrow + Uvs black cinder”, Group 2 “Yellow marrow + Uvs brown red cinder”, Group 3 “Yellow marrow + Chinese red cinder”, Group 4 “Yellow marrow + Chinese white cinder”, Standard “Mebo” wound ointment. The wound area was prepared by scraping the hair 5 cm from the back of the test animal’s skull. The prepared area was sterilized with 70% ethanol and 10% iodine solution, resulting in a third-degree burn wound of 2.4 cm2. Wound experiential’s ointments were applied once daily for a total of 28 days, and wound healing was evaluated at 0, 3, 7, 14, 21, and 28 days after pathogenesis, with 16.1-pixel accuracy. Photo confirmed using a SONY brand camera. Result: “CIBO” ointment contains four deferent cinders which are from collected from deferent area and that have been shown to good affect burn wounds, and is more compatible with yellow marrow than Group 4 (Yellow marrow+Chinese white cinder).
Wound healing variables of control group compared with group 4 (Yellow marrow + Chinese white cinder) increased by 11.1% on the 3th day, 4% on the 7th day, 44.8% on the 14th day, and 54.5% on the 21st day. On the 28th day, healing and regeneration were accelerated by 50%. Conclusion The group 4 (Yellow marrow + Chinese white cinder) has been shown to have a pharmacological action of rapid healing and regeneration of burn wounds caused by experimental rats. It has also been shown to have pharmacological action to regenerate skin tissue and suppress inflammation caused by burns. Inclusion of Chinese white cinder in “CIBO” ointment promotes regeneration and healing of “CIBO” ointment.

Introduction: In Mongolia, there is opportunity to replace importing products by using raw materials based on the animal and minerals. Those products can be used for medical purposes.
In traditional medicine, yellow marrow has been widely used to treat burns and mechanical wounds, as well as frozen and open wounds. The purpose of this study was to determine the pharmacological action of “CIBO” ointment. We created a model of mechanical wound to evaluate the healing of wounds and its index after applying the ointment contains the above mentioned raw materials. Material and methods: Four different groups of “CIBO” ointment was prepared in the technology sector of the Drug Research Institute. Mebo wound ointment was used for comparison as control. The study was con- ducted in the Pharmacology Sector of the Drug Research Institute on white rats of the WISTAR breed under one feeding regime and one condition (12h / 12h). Mechanical wound injury and exposure to open wounds in experimental rats and its size were measured on the 3^rd, 7^th, 14^th, 21^st, and 28^th days of treatment. Wound healing, morphology, structure, size, and its index was quan- tified based on the defects. The ointment were applied once a day during the treatment period of 28 days to cover the wound. Result: Mechanical wound showed that study treatment group healed 0-6.2% on the 3^rd day, 21.4-35.7% on the 7^th day, 50-60% on the 14^th day, and 33.3-50% on the 21^st day separately compared with the untreated group. On the 28^th day, all the groups were decreased by 66.6%. The wound index was between from 0.002 to 0.0005 in the all experimental groups. Among experimented groups, the group consists of yellow marrow and Chinese white cinder was showed better performance than other groups. Conclusion The study group 4 (Yellow marrow + Chinese white cinder) has been showed to have a pharmacological action of rapid healing and regeneration of burn wounds caused by experimental rats. It has also been shown to have pharmacological action to regenerate skin tissue and suppress caused by mechanicals. Inclusion of Chinese white cinder in “CIBO” ointment promotes regener ation and healing of “CIBO” ointment.

Results: The result showed no structural changes in the internal organs according to tissue morphology when we administrated CHUN-7 traditional drug. Conclusion This study showed CHUN-7 traditional drug has no toxic effects to internal organs including liver, kidney, stomach, lungs and heart. Therefore, CHUN-7 traditional drug has potential to use orally without any toxicology.

Introduction: Studies in many countries have found that the satisfaction of medical workers is closely linked to the quality and efficiency of medical services, as well as the satisfaction of patients. Satisfied employees will bring about satisfied clients. The satisfaction of employees remains a key factor linking the internal management and external management of an organisation. The World Health Organization (WHO) Global strategy on human resources on health workforce 2030 sets out the policy agenda to ensure a workforce that is ft for purpose to attain the targets of the Sustainable Development Goals (SDGs). Motivation of health care workers can initiate them to exert and maintain an efort towards organizational goals. Motivation depends up on many factors, and job satisfaction is one of the most important factors. Healthcare is a service industry where the overall service experience is important for customer satisfaction and quality of care (even if in different extents according to the professional at stake) and that the literature has been bringing about the pertinence of such a holistic approach, this research was conducted within this perspective. Likewise, it is also known that there is close correlation between the job satisfaction of health care staff and the total quality of health services. Different groups have reported differences between the job satisfaction of doctors and that of other health providers. Various satisfaction levels of health care workers, including general practitioners, nurses and midwives, have been reported previously. Materials and Methods: This study was performed at the Amgalan Maternity Hospital, Urguu Maternity Hospital and Khuree Maternity Hospital The study involved 480 employees of above mentioned hospitals. The short form of the Minnesota Satisfaction Questionnaire, with 20 items, was used to examine satisfaction with professional life. The self-administered questionnaire was distributed to all people at their workplaces. Responses of 4 (satisfied) or 5 (very satisfied) were classified as ‘satisfied’, those of 1 (very dissatisfied) or 2 (dissatisfied) as ‘dissatisfied’. Results: The study recruited total 480 employees consisting of 220 employees working at Urguu Maternity Hospital, 125 employees of Khuree Maternity Hospital and 135 employees of Amgalan Maternity Hospital. 46 administration officials, 75 doctors, 208 nurses and obstetricians, 105 caregivers and service assistants and 46 economic employees involved it. In table, 87.1% of total employees of maternity hospitals were female and 12.9% were male. While there had significantly difference for gender, occupation type and worked year in this sector and workplace between 3 maternity hospitals (p<.001), age and education level had no significantly difference between these 3 groups. The proportion of health care staff satisfied with their work was 80.7%. The chance to tell people what to do’ and ‘Being able to do things that do not go against my conscience’, and mostly dissatisfied with ‘The working conditions’ and ‘My pay and the amount of work I do’. There was no significant difference between satisfaction scores of health care staff according to age, gender, marital status, and experience of profession. When the 20 items constituting job satisfaction were examined specifically, the satisfaction score showed a difference related to profession. The midwives’ satisfaction score was significantly lower than that of the others. In table 4, to assess employee’s satisfaction of each maternal hospital: While the minimum satisfaction was assessed by employees of Urguu maternity hospital whether salary is equal for work performance, the maximum satisfaction was assessed by employees of Amgalan maternity hospital under scope of consistent workplace at 93.9 percent. Conclusion Maternity satisfy external and internal factors of employees are influenced. Maternity is different, depending on the satisfaction of other working areas of employment.

Background: Postpartum readmission rate has been increasing after both caesarean and vaginal delivery. Postpartum diseases, in some cases with infection and anemia, result in hospital readmission. Also it raises the issue associated with maternal hospital’s healthcare quality. There has lack of study focusing on postpartum readmission. So we will study postpartum readmission rate. Material and Methods: 112 patients who readmitted in Amgalan maternity hospital in Ulaanbaatar were involved in this study. We used patient’s medical history to determine risk factors resulted in hospital readmission after caesarean and vaginal therapy. Results: The mean age of women delivered by cesarean was 30.2±7.32 and vaginal delivery’s was 28.3±7.21. 34.8 percent of women who readmitted after vaginal delivery had 1-3 readmission days and 56.5 percent was 4-6 days and 8.7 percent was 7-10 days. Readmission day for women delivered by caesarean was 1-3 days in 21.2 percent of these, 4-6 days in 56.1 percent and 7-10 days in 19.7 percent. The mean readmission day of women delivered by vaginal delivery was 4.73±1.61 (mean±SD) and the mean of women delivered by caesarean delivery was 5.54±2.34 (mean±SD). In each category, there had 24.2-28.3 percent cases with lochia. Women who had caesarian delivery were infected their scar with 24(36.3) cases. Renal urinary system infection had in 12(26.0) women delivered by vaginal delivery. Conclusion 58.9 percent of total readmissions cases were caesarean and 41.1 percent was vaginal delivery. Lochia and renal urinary infection had influence in readmission after vaginal delivery. Also both lochia and infected wound impacted on postpartum readmission after caesarian delivery.
