Alat Pengaman Ruangan dengan Closed Circuit Television (CCTV)
Akhir-akhir ini banyak orang yang resah jika mereka harus terjaga selama 24 jam setiap hari terutama para petugas keamanan, karena keamanan ruangan yang sangat rawan. Hal ini kurang efektif. Dengan teknologi yang semakin berkembang belakangan ini sangat mungkin, bila sudah waktunya, orang tidak lagi takut bila ingin meninggalkan ruangan atau ingin beristirahat sebentar terutama bagi petugas keamanan di suatu raungan. Oleh karena itu, diperlukan suatu alat untuk mendeteksi gerakan secara real time untuk mencegah ancaman pencurian pada suatu ruangan tertentu. Dalam jurnal ini dirancang suatu sistem yang melibatkan teknologi mikrokontroler di mana sistem tersebut akan melakukan pengambilan gambar secara real time dengan kamera Closed Circuit Television (CCTV), kemudian dilakukan proses perbandingan frame(t) dengan frame(t-1), jika selisih dari perbandingan tersebut melebihi nilai toleransi tertentu, maka hal tersebut dianggap sebagai gerakan. Setelah gerakan terdeteksi, maka komputer akan mengirim sinyal ke mikrokontroler untuk mengaktifkan sistem dari alat tersebut. Hasil yang dapat diperoleh dari 30 pengujian dari alat terhadap obyek yang bergerak ke kiri dan ke kanan, memiliki persentase keberhasilan 93, 3% dan persentase kegagalan 6,67%
Paternal Genetic History of the Basque Population of Spain
This study examines the genetic variation in Basque Y chromosome lineages using data on 12 Y-short tandem repeat (STR) loci in a sample of 158 males from four Basque provinces of Spain (Alava, Vizcaya, Guipuzcoa, and Navarre). As reported in previous studies, the Basques are characterized by high frequencies of haplogroup R1b (83%). AMOVA analysis demonstrates genetic homogeneity, with a small but significant amount of genetic structure between provinces (Y-short tandem repeat loci STRs: 1.71%, p 0.0369). Gene and haplotype diversity levels in the Basque population are on the low end of the European distribution (gene diversity: 0.4268; haplotype diversity: 0.9421). Post-Neolithic contribution to the paternal Basque gene pool was estimated by measuring the proportion of those haplogroups with a Time to Most Recent Common Ancestor (TMRCA) previously dated either prior (R1b, I2a2) or subsequent to (E1b1b, G2a, J2a) the Neolithic. Based on these estimates, the Basque provinces show varying degrees of post-Neolithic contribution in the paternal lineages (10.9% in the combined sample)
Autosomal short tandem repeat genetic variation of the Basques in Spain
Aim
To examine population genetic structure and hypotheses of the origin of the modern Basque population in Spain using autosomal short tandem repeat (STR) data from individuals living in 27 mountain villages in the provinces of Alava, Vizcaya, Guipuzcoa, and Navarre, by comparing Basque autosomal STR variation with that of neighboring populations in Europe, as well as proposed ancestral populations in North Africa and the Caucasus.
Methods
Allele frequencies for 9 autosomal STR loci (D3S1358, D5S818, D7S820, D8S1179, D13S317, D18S51, D21S11, FGA, and vWA) and several population genetic parameters were determined for the 4 provinces in the Basque region of Spain (n = 377). Heterozygosity within the Basque population was measured using a locus-by-locus analysis of molecular variance. Relationships between the Basques and other populations were examined using a multidimensional scaling (MDS) plot of Shriver’s DSW distance matrix.
Results
Heterozygosity levels in the Basque provinces were on the low end of the European distribution (0.805-0.812). The MDS plot of genetic distances revealed that the Basques differed from both the Caucasian and North African populations with respect to autosomal STR variation.
Conclusions
Autosomal STR analysis does not support the hypotheses of a recent common ancestor between the Basques and populations either from the Caucasus or North Africa.Funding This work is supported in part by National Geographic Society Grant (Project 6935-00) to the University of Kansas Laboratory of Biological Anthropology
Pengaruh Waktu Hidrolisis Dan Konsentrasi Katalisator Asam Sulfat Terhadap Sintesis Furfural Dari Jerami Padi
-Rice straws are one of the hemicellulose-contained wastes, which one of its main components is pentosan. Pentosan can be reacted into furfural with acid catalytic hydrolysis reaction. This research is intended to find out the effect of hydrolysis durations and sulfuric acid (H2SO4) catalyst concentrations towards yield of furfural from rice straws. The synthesis of furfural from rice straws is conducted by refined the rice straws, then hydrolyze it with different concentrations of sulfuric acid solution (1%, 3%, and 5% v/v) and with different durations of hydrolysis reaction (1 hour, 2 hours, 3 hours, 4 hours, dan 5 hours). This hydrolisis reaction produced liquid, which are distilled to separate furfural from sulfuric acid solution. The results of this research show the yield of furfural from rice straws hydrolysis is inversely proportional to sulfuric acid catalyst concentration and hydrolysis duration. The best yield of furfural was 5,441%, which obtained with 1% sulfuric acid catalyst concentration and 1 hour hydrolysis duration
Awareness of palliative care among general nursing and midwifery nurses in nursing institutes of Assam by palliative care quiz for nursing tool
Background: Amidst the increasing prevalence of non-communicable diseases and an aging populace, the demand for palliative care (PC) is escalating. Nurses, as primary caregivers in healthcare, play a pivotal role in providing PC. Assessing their current knowledge levels is crucial for devising targeted strategies to address deficiencies and enhance the quality of palliative care delivery.
Methods: A survey-based study was done in 10 nursing institute across Assam which were selected randomly after obtaining ethical committee clearance from the institute. A total of 239 participants filled the questionnaires. The questionnaire contained 2 parts; sociodemographic characteristics and palliative care quiz for nursing (PCQN) which is a validated questionnaire consisting of 20 items that measures nurses’ knowledge of palliative care. The responses to the statements in the PCQN will be: true, false, and I don’t know. A correct answer was scored 1 while an incorrect or I don’t know was scored 0, giving a maximum score of 20. A score equal to or less than ≤10 on PCQN was considered inadequate knowledge while a score >10 was considered adequate knowledge.
Results: 55% participants had adequate knowledge about palliative care and the mean PCQN score was 12.59±5.8. P value was found to be significant which means those with prior knowledge of palliative care had good score.
Conclusions: This study underscores a positive shift in palliative care awareness among nursing students, attributed to curriculum integration. However, targeted improvements are needed, especially in psychosocial and spiritual aspects, to enhance patient care and attitudes

Neighbouring Link Travel Time Inference Method Using Artificial Neural Network
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.This paper presents a method for modelling relationship between road segments using feed forward back-propagation neural networks. Unlike most previous papers that focus on travel time estimation of a road based on its traffic information, we proposed the Neighbouring Link Inference Method (NLIM) that can infer travel time of a road segment (link) from travel time its neighbouring segments. It is valuable for links which do not
have recent traffic information. The proposed method learns the relationship between travel time of a link and traffic parameters of its nearby links based on sparse historical travel time data. A travel time data outlier detection based on Gaussian mixture
model is also proposed in order to reduce the noise of data before they are applied to build NLIM. Results show that the proposed method is capable of estimating the travel time on all traffic link categories. 75% of models can produce travel time data with mean absolute percentage error less than 22%. The proposed method performs better on major than minor links. Performance of the proposed method always dominates performance of traditional methods such as statistic-based and linear least square estimate methods
