THE STUDY OF VISUAL MEDIA USE ON DEAF CHILDREN IN SCIENCE LEARNING

This study aims to: (1) describe the implementation of science teaching deaf children in class XI, and (2) describe and analyze the use of visual media in science teaching deaf children in class XI. This study used a qualitative descriptive method. Source of research data are teachers, students and principals. The technique of collecting data used was interviews, documentation and observation. SLB research sites in Sukoharjo district, which includes SLB ABCD YSD Polokarto, SLB Hamongputro Jombor B-C, B-C SLB YPALB Langenharjo and SLB ABC Tawangsari. The data were analyzed through data reduction, data display and draw conclusions. Conclusions are presented in the form of narrative text form field notes. The results showed that (1) the implementation of science teaching deaf children in class XI SLB Sukoharjo still using conventional methods with students to make a note of the material presented (2) the use of visual media in science teaching deaf children in class XI SLB Sukoharjo regency is still minimal because it only uses media images and text books provided in the school.  Article visualizations

STUDI IMPLEMENTASI KEBIJAKAN KONVERSI JABATAN STRUKTURAL KE JABATAN FUNGSIONAL BIDANG KEARSIPAN DI KEMENTERIAN SEKRETARIAT NEGARA

Simplification of the government organizational structure into 2 (two) levels only and then transferring it to functional positions and valuing expertise and competence is a policy taken by the President of the Republic of Indonesia in the context of implementing bureaucratic reform in order to improve the professionalism and quality of public services. The implementation of the policy of converting structural positions to functional positions in the field of archives at the Ministry of State Secretariat has several effects on the implementation of archival tasks and functions. This research uses a descriptive method with a qualitative approach conducted at the Bureau of Administration and Presidential Archives of the Ministry of State Secretariat. Data sources were taken from interviews with key informants and informants, the results of field observations, and several related laws and regulations documents. This research uses George Erdward III's policy implementation theory and SWOT analysis. The results of the research obtained several supporting factors for the implementation of the position conversion policy, namely that the policy in question is a policy that comes from top management to bottom management, the Associate Expert Archivist and Junior Expert Archivist resulting from the conversion of positions do not experience a decrease in takehome pay, the retirement age of the Associate Expert Archivist is increasing in length. While the inhibiting factors for the implementation of the position conversion policy are the miscommunication between the leadership and the archiving working group, the implementation of archiving tasks is not effective because of the range of control.   Keywords: Job conversion, Structural Position, Functional Position, Archivist &nbsp

Pembuatan Metil Ester Sulfonat dari Refined Bleached Deodorized Stearin Minyak Sawit Menggunakan Oleum

PEMBUATAN METIL ESTER SULFONAT DARI REFINED BLEACHED DEODORIZED STEARIN MINYAK SAWIT MENGGUNAKAN OLEUM. Telah dilakukan proses pembuatan metil ester sulfonat dengan menggunakan oleum sebagai sumber SO3. Beberapa variabel proses seperti suhu dan perbandingan mol antara SO3 dan metil ester telah dilakukan untuk mendapatkan kondisi optimal untuk proses sulfonasi yang menggunakan reaktor falling film. Kondisi proses yang optimal diperoleh pada suhu antara 80 0C hingga 90 0C. Perbandingan mol reaktan 1,2 menghasilkan kandungan bahan aktif sebesar 93%. Metil ester sulfonat yang diperoleh dengan bilangan iod 1,15, tegangan permukaan 29 dyne/cm dan 180 klett sebagai indikasi warna

The Effect of Preterm Birth on Thalamic and Cortical Development

Preterm birth is a leading cause of cognitive impairment in childhood and is associated with cerebral gray and white matter abnormalities. Using multimodal image analysis, we tested the hypothesis that altered thalamic development is an important component of preterm brain injury and is associated with other macro- and microstructural alterations. T1- and T2-weighted magnetic resonance images and 15-direction diffusion tensor images were acquired from 71 preterm infants at term-equivalent age. Deformation-based morphometry, Tract-Based Spatial Statistics, and tissue segmentation were combined for a nonsubjective whole-brain survey of the effect of prematurity on regional tissue volume and microstructure. Increasing prematurity was related to volume reduction in the thalamus, hippocampus, orbitofrontal lobe, posterior cingulate cortex, and centrum semiovale. After controlling for prematurity, reduced thalamic volume predicted: lower cortical volume; decreased volume in frontal and temporal lobes, including hippocampus, and to a lesser extent, parietal and occipital lobes; and reduced fractional anisotropy in the corticospinal tracts and corpus callosum. In the thalamus, reduced volume was associated with increased diffusivity. This demonstrates a significant effect of prematurity on thalamic development that is related to abnormalities in allied brain structures. This suggests that preterm delivery disrupts specific aspects of cerebral development, such as the thalamocortical system

Global and Regional Differences in Brain Anatomy of Young Children Born Small for Gestational Age

In children who are born small for gestational age (SGA), an adverse intrauterine environment has led to underdevelopment of both the body and the brain. The delay in body growth is (partially) restored during the first two years in a majority of these children. In addition to a negative influence on these physical parameters, decreased levels of intelligence and cognitive impairments have been described in children born SGA. In this study, we used magnetic resonance imaging to examine brain anatomy in 4- to 7-year-old SGA children with and without complete bodily catch-up growth and compared them to healthy children born appropriate for gestational age. Our findings demonstrate that these children strongly differ on brain organisation when compared with healthy controls relating to both global and regional anatomical differences. Children born SGA displayed reduced cerebral and cerebellar grey and white matter volumes, smaller volumes of subcortical structures and reduced cortical surface area. Regional differences in prefrontal cortical thickness suggest a different development of the cerebral cortex. SGA children with bodily catch-up growth constitute an intermediate between those children without catch-up growth and healthy controls. Therefore, bodily catch-up growth in children born SGA does not implicate full catch-up growth of the brain
