The purpose of this study was to determine the effect of the intensity of group learning activities and student motivation on learning outcomes in the electrical lighting installation subjects of class XI students at 34 State Vocational Schools in Jakarta. The method used in this study is a survey with a causal approach and research subjects (respondents) are not manipulated or given special treatment by researchers. The results of the research with a causal approach are analyzed using path analysis with a significance level of 5%. Results research shows that the path coefficient value (ρ31) amounting to 0.170, with thitung = 3,088 and ttabel = 1,6716 on α = 0,05, That mean significant path coefficient because of value thitung> ttabel atau 3,088> 1,6716. Thus, from these findings it can be interpreted that learning motivation (X2) has a direct effect on learning outcomes (X3) of 16.32%. Value of path coefficient (ρ31) amounting to 0.170, with thitung = 1,206 And ttabel = 1,6716 on α = 0,05, that mean path coefficient value is not significant because the value of thitung <ttable or 1.206 <1.671. Thus, from these findings it can be interpreted that the intensity of group learning activities (X1) does not directly influence learning outcomes (X3) and indirectly influence learning motivation (X2) on learning outcomes of 3.67%.

The purpose of this study was to determine the relationship between learning independence and students' perceptions of the completeness of learning facilities with basic learning outcomes of electricity and electronics at SMK 34 Jakarta. This research was conducted at SMKN 34 Jakarta with a total sample of 65 students of class X Electricity in the subjects of Basic Electricity and Electronics.
The method used in the study is ex post facto with this type of qualitative research. This study uses the ex post facto method with a quantitative approach. The results obtained stated that there was a positive and significant relationship between learning independence and students' perceptions of the completeness of learning facilities with learning outcomes with a large value of r count = 0.725 and fcount = 34.38 with learning independence influencing learning outcomes by 52.56%.
So that, it can be implied that the higher the independence of student learning and the more complete learning facilities available, the higher student learning outcomes, and vice versa, the lower the independence of student
learning and the complete lack of learning facilities that exist make student learning outcomes also low.

The purpose of this research is to get the strong value of lighting at L1 building of Universitas Negeri Jakarta and compare the measurement result using luxmeter with software of Dialux Evo 6.2. This research uses engineering methods by utilizing three ways of measurement, manual calculation and simulation of Dialux Evo 6.2. Measurement method using Luxmeter as measuring instrument to get the measured value of the measured light in the learning room based on the standard procedure of calculation according to SNI and the simulation using the program of Dialux Evo 6.2 to predict the strong value of the illumination that should be in the building.
The results of this study indicate that the average value of the average light is still not much according to the standard. Then by manual calculation and simulation, the strong value of illumination that should be in the building is also below 350 lux for study room, under 500 lux for laboratory, and under 750 lux for technic al drawing room. Then to improve the design of the high rise building, to achieve a strong value of lighting above 350 lux, 500 lux and 750 lux can be obtained by changing the wall color characters that increased to reach 3- 9.6 percent, a 52-84 percent increase after changing the point of light , as well as an increase of 54-85 percent after changing the color of the walls and the point of light.

The researcher precieved the poor results from the students who have not achieved the standard completion of studies (SKB) during and after they underwent and internalized learning activities in the process of their study. The objective of this research is to realize the difference between the results of study on Electrical Lighting Installation using Contextual Teaching and Learning method and the result of the study using the Convensional method in grade XI TITL, SMK Dinamika Pembangunan 1 Jakarta. The hippotetical test using t–test resulted in t-counted = 2.32 at the significance of α = 0.05 and the 45 level of tolerance which resulted in t-table = 2.00. Therefore, the value is within the area of acceptance of H1 and rejection of H0. This shows that the average result of study using the Contextual Teaching and Learning model is better compared to the result of study using the conventional model.

Sustentaculum Tali Fracture Adjacent to Talocalcaneal Tarsal Coalitions
Authors: Kehoe Clare M. , Scher David M. 
Published: March 2021

Case:
An 11-year-old boy demonstrated chronic medial hindfoot pain. A 12-year-old boy experienced acute pain and swelling in his right medial ankle and hindfoot after a fall. This is the first report of sustentaculum tali fractures adjacent to a talocalcaneal tarsal coalition, likely resulting from a stress riser created by a rigid subtalar joint.

Conclusion:
These 2 cases represent unique causes of foot pain in the setting of tarsal coalitions, never before described. Patient-reported outcome measures demonstrated expected improved outcomes after excision of tarsal coalition. Awareness to this possibility will help clinicians treating foot and ankle conditions in children optimize their care.
Satisfactory Outcome for a Challenging Case of Infected Native Pelvic Discontinuity with Significant Bone Loss
Authors: Hafez Mahmoud A. , Makram Omar Mohamed , Seth Vikas J. 
Published: March 2021

Case:
This is a challenging case of infected native pelvic discontinuity with massive acetabular bone loss. The infection was persistent despite repeated debridement. A new technique of articulated antibiotic spacer plus Mexican hat antibiotic spacer has been used. A triflanged custom-made implant was used in the second-stage surgery. The 2-year follow-up showed no recurrence of infection and no loosening.

Conclusion:
Using a Mexican hat spacer is a good option when there is a massive bone loss medially. Custom-made triflanged cup showed to be a viable treatment modality for infected pelvic discontinuity despite the cost of the implant.
Performance assessment of a multi-epitope chimeric antigen for the serological diagnosis of acute Mayaro fever

Abstract
Mayaro virus (MAYV) is endemic to limited regions of South America and the possible involvement of Aedes spp. mosquitoes in its transmission increase the risk that its geographical range will reach greater populations. MAYV shares clinical symptoms and structural similarities with other emerging members of the alphavirus family such as Chikungunya (CHIKV), Ross River (RRV), and O'nyong nyong (ONNV) viruses, which complicate diagnosis and is currently restricted to nucleic acid-based tests. Effective control of the spread of these diseases will require the identification of infected individuals as well as the development of preventative and prophylactic therapies. Serological tests have a greater potential to expand testing at a reasonable cost than molecular approaches. Their performance largely reflects that of the antigen utilized to capture pathogen-specific antibodies. Here, we describe the assembly of a synthetic gene coding multiple copies of antigenic determinants mapped from the nsP1, nsP2, E1, and E2 proteins of MAYV that readily produced a stable chimeric protein in bacteria. The serological performance (AUC, sensitivity, specificity, and confidence intervals) of this multi-epitope protein as the target in ELISAs revealed a high diagnostic accuracy for the detection of specific anti-MAYV IgM antibodies. No cross-reactivity was observed with serum from seropositive individuals for CHIKV, yellow fever (vaccinated), dengue, Zika, and other infectious diseases as well as healthy individuals. Our data suggest that this bioengineered antigen could be used to develop high-performance serological tests for MAYV infections.
