FAKTOR RESIKO PENYAKIT TB (TUBERKULOSIS) DI KECAMATAN KABANJAHE KABUPATEN KARO TAHUN 2021

Tuberculosis (TB) is a direct infectious disease caused by TB (mycobactic tuberculosis) germs. The disease is still in the attention of the world and until now, there are no one neither country free from TB. Deli Serdang regency is an regency with the highest Tuberculosis case discovery in North Sumatra Province. This study was observational research with the design of study control cases, in order to determine the characteristics of the patient and the risk factor for the tuberculosis incident. The number of samples is 45 cases and 45 controls. The characteristic association and risk factors with the incidence of tuberculosis were analyzed in univariat and bivariat, Analysis is carried out using cross-con 2x2 to calculate the value of prevalen ratios and confidence values (CI). Statistical test used for analysis is chi square at the trust rate 95% (? = 5%). The results of the lighting study are obtained from the value of OR 0.348, CI 0.144 - 0.840 and p-value 0,031. Residence density obtained from the OR 0.35 CI 0.142 - 0.700 p-value 0.020 and Venting obtained from the OR 0,348 CI 0,144 – 0,840 p-value 0.031. Lighting, venting, and residence density have a relation with the incident TB in Kabanjahe District, while the variables with no relation are temperature, moisture and house floor condition.

Major Causes of Calf Morbidity and Mortality in Smallholder Dairy Farms in Shashemene Town, Ethiopia

A cross-sectional study was conducted to determine the major causes of calf morbidity and mortality in smallholder dairy farms and associated potential risk factors in Shashemene. A total of 187 calves from 46 farms were included in the present study. The overall crude morbidity and crude mortality rates were 27.8% and 6.4%, respectively. The most frequent disease syndrome was diarrhea with incidence rate of 28(15%) followed by pneumonia 8(4.3%), Gastrointestinal tract (GIT) disorder 8(4.3%) and septicemia 5(2.7%). In addition skin lesion, navel ill and unidentified cases were encountered. The main causes of death were diarrhea 6(3.2%), Septicemia 2(1.1%), GIT disorder 2(1.1%), pneumonia 1(0.5%) and others 1(0.5%). The most important risk factors associated with morbidity and mortality were housing hygiene, floor condition and calf size in farm. Out of 187 calves examined for GIT parasites; 63(33.3%) were positive for nematode eggs. Prevalence of helminthes parasite increased with increasing age, showing higher prevalence (P<0.05) in calves above 2 months than in calves below 2 months of age. Besides, majority of the calves, 48(25.7%) were found positive for coccidian oocyst. In general; diarrhea, pneumonia and septicemia were the major causes of calf morbidity and mortality. Interms of risk factors housing hygiene, floor condition, calf size in the farms, age and breed were identified major role players. Therefore, identifying major causes and improving management practices and breed should be given to emphasis by advisory of smallholder dairy farms.

Effect of foot–floor friction on the external moment about the body center of mass during shuffling gait: a pilot study

Herein, we investigated the effect of friction between foot sole and floor on the external forward moment about the body center of mass (COM) in normal and shuffling gaits. Five young male adults walked with normal and shuffling gaits, under low- and high-friction surface conditions. The maximum external forward moment about the COM (MEFM-COM) in a normal gait appeared approximately at initial foot contact and was unaffected by floor condition. However, MEFM-COM in a shuffling gait under high-friction conditions exceeded that under low-friction conditions (p < 0.001). Therein, MEFM-COM increased with an increasing utilized coefficient of friction at initial foot contact; this effect was weaker during a normal gait. These findings indicate that increased friction between foot sole and floor might increase tripping risk during a shuffling gait, even in the absence of discrete physical obstacles.

Duration of Contact, Type of Leprosy, And Floor Condition As Risk Factors For Leprosy Sero-positivity

The high number of leprosy seropositivity in a population may lead to clinical leprosy. This study aimed to identify risk factors of leprosy. This study was conducted in Brondong, Lamongan, East Java. The subjects were 153 people who lived with leprosy patient. lgM anti PGL-1 level was examined used ELISA (Dako). Logistic regression was conducted to test the independent variables. The results showed that the subjects had an average age 31 year (6.5), average BMI 22 (2.9) and average IgM anti PGL-1 level 1041 unit/ml (820). 79.7% of the research subjects were women. The subjects house floor condition (p value 0.009) was the most influential variable to seropositivity of leprosy. Our findings indicated that not only the duration of leprosy and the contacts need to be considered in the transmission of leprosy, but also environmental factors, such as the subjects house floor condition.

Effect of Flooring on Lower Extremity Discomfort during Food Service Tray-line Jobs

This paper investigate the extent to which flooring mats affect stress and fatigue among food service workers on trayline duties. A food service trayline job was simulated in the lab to study the effect of the flooring mat on the lower leg swelling, muscle temperature, fatigue levels and discomfort levels. Six participants participated in the study and performed a 1-hour simulated trayline job. Results showed a significant effect of flooring condition on the muscle temperature change in Tibialis Anterior and Quadriceps with decreasing trend observed for hard floor condition. Results also indicated an increasing trend for leg volume and higher fatigue and discomfort in hard floor condition.

LAND-SEA INTERACTIONS IN COASTAL WATERS OFF NE KALIMANTAN: EVIDENCE FROM MICROFAUNAL COMMUNITIES

Microfauna (ostracoda and foraminifera) as component of sediments has been used to detect the dynamics of sea floor condition in NE Kalimantan, particularly off Nunukan and Sebatik Islands. In general, the microfaunal components tend to increase (both number of species and specimens) from near shore to the open sea. The microfauna occur rarely at locations surrounding the islands due to high content of plant remains from the land. The marine origin of microfaunas occurs very abundantly in the inner part of the study area between Tinabasan and Nunukan Islands. This finding is interested due to their occurrence as unusual forms: brownish shells, broken and articulated ostracod carapaces. Additional interested findings are: the incidence of abraded test of Elphidium, the occurrence of dominant species of both ostracoda and foraminifera at some stations; various morphological forms of foraminiferal genus, Asterorotalia that reaches about 1% and distributed in the open sea. The various unusual forms may relate to the dynamics of local environmental changes such as postdepositional accumulation in the sediment, biological activities, and drift currents from open sea to landward. Keywords: Ostracoda, Foraminifera, North East Kalimantan, land-sea interaction Mikrofauna (ostracoda dan foraminifera), sebagai komponen sedimen dapat digunakan untuk mendeteksi dinamika kondisi dasar laut di Kalimantan Timur, tepatnya di sekitar Pulau Nunukan dan Sebatik. Secara umum, komponen mikrofauna cenderung bertambah (baik dalam jumlah spesies maupun spesimen) dari perairan sekitar pantai ke arah laut lepas. Mikrofauna yang ditemukan sangat jarang di lokasi sekitar pulau-pulau disebabkan oleh keterdapatan sisa-sisa tanaman dari daratan. Mikrofauna asal lautan ditemukan sangat melimpah di bagian dalam daerah penelitian antara Pulau Tinabasan dan Nunukan. Temuan ini sangat menarik karena adanya bentukan abnormal: cangkang berwarna kecoklatan, rusak dan cangkang ostracoda berbentuk tangkupan. Temuan tambahan yang juga menarik adalah: keterdapatan cangkang Elphidum yang rusak, keterdapatan beberapa spesies ostracoda dan foraminifera secara dominan di titik lokasi tertentu, dan kenampakan morfologi yang bervariasi dari genus foraminifera, Asterorotalia, yang mencapai 1% dan tersebar di laut lepas. Berbagai bentukan abnormal tersebut kemungkinan berkaitan dengan dinamika kondisi lingkungan setempat seperti akumulasi setelah pengendapan dalam sedimen, aktivitas biologis dan alur arus dari laut terbuka kearah daratan. Kata kunci: ostracoda, foraminifera, Kalimantan Timur, interaksi daratan-lautan
