"The most difficult part of making decisions in the health care field on all levels (national, regional, institutional, patient) is linked to the very complexity of the system itself, to the intrinsic uncertainty involved and its dynamic nature. This requires not only the ability to analyze and interpret a large amount of information but also arrange it so that it becomes a cognitive base for appropriate decision-making. Moreover, decisions in the health care field are subjected to many challenges and constraints: fast change and uncertain outcomes, aging population, increasing citizen expectations, equity considerations and limited resources. Operations research, statistical and economic-related quantitative methods supply these decisions making tools and methodology. The contributed book presents a collection of applications to concrete situations detailing the problem area, the methodology employed, the implementation and results. Each topic addressed in the book will be structured in such a way that an interdisciplinary and wide audience will be able to use the materials presented. As an example the book chapters will address health policies issues, planning health services, epidemiology and disease modelling, home-care modelling, logistics in health care, capacity planning, quality and appropriateness."

Using panel data regression method, the results of the study found that the interaction between democracy and countries in Asia influences trade. However, it was found that trade in high-income countries was not affected by democracy, whereas trade in low-income countries was strongly influenced by democracy."

"Latar Belakang: Preeklamsia mempengaruhi 2-10% kehamilan di dunia, sehingga preekalmsia merupakan penyebab utama mortalitas dan morbitidas pada ibu dan kehamilan. Di Indonesia, preeklamsia menyerang sejak usia kandungan dini, yang membahayakan janin dan ibu. Namun, pengetahuan mengenai patogenesis dan perkembangan preeklamsia belum sepenuhnya diketahui. Untuk itu, pengetahuan mengenai patogenesis dari preeklamsia yang sangat dikorelasikan dengan stres oksidatif pada plasenta sangatlah penting. Metode: Penelitian ini merupakan penelitian pionir dengan rancang potong lintang. Sampel penelitian adalah 12 plasenta dari kehamilan normal, 12 plasenta dari preeklamsia onset lambat, dan 4 plasenta dari preeklamsia onset awal dari RS Ciptomangunkusumo dan RSIA Budi Kemuliaan. Dilakukan perhitungan konsentrasi MDA dengan metode Wills. Data dianalisa menggunakan program SPSS versi 20 untuk Macbook melalui uji komparasi Kruskal Walis dilanjutkan dengan uji post hoc Mann Whitney. Hasil: Konsentraasi MDA pada kehamilan normal, preeklamsia awal, dan preeklamsia lambat secara berturut-turut adalah 0,147, 0,033 dan 0,015. Uji Kruskal Walis menunjukkan, terdapat perbedaan konsentrasi MDA bermakna antara kehamilan normal, preeklamsia onset awal dan preeklamsia onset lambat (p < 0,001). Pada uji Mann Whitney, MDA plasenta kehamilan normal lebih tinggi secara signifikan dibanding preeklamsia onset lambat (p < 0,001). Namun, tidak terdapat perbedaan berarti antara MDA preeklamsia onset cepat dengan lambat (p=0,133) dan antara MDA pada kehamilan normal dengan MDA preeklamsia onset awal (p = 0,011). Kesimpulan: Terdapat penurunan kadar ROS pada PE onset lambat yang diindikasikan oleh level peroksidasi lipid yang secara signifikan lebih rendah dibandingkan kehamilan normal. Namun, tidak terdapat penurunan kadar ROS pada PE onset awal dari kadar normal, dilihat dari tidak adanya perbedaan signifikan pada kadar MDA. Kedua hal ini memiliki peranan dalam perkembangan PE onset awal dan onset akhir pada masyarakat Indonesia.

Background: Affecting 2-10% of pregnancies worldwide, preeclampsia is the leading cause of maternal and perinatal morbidity and mortality. In Indonesia, preeclampsia emerges in early gestational age, which endangers the mother and fetus. However the pathogenesis of preeclampsia is not yet known. Hence, it is important to understand pathogenesis of preeclampsia, which is highly correlated to oxidative stress in placenta.

Methods: This research was a pioneer research with the design of a cross sectional comparative study. As this research is a pioneer study, the sample size is based on pioneer study sample size, so 12 placenta tissues for each group were attained. The MDA concentration was measured using Wills method. Data is being analyzed using SPSS version 20 for Macbook with Kruskal Walis as hypothesis test and Mann Whitney as post hoc test.

Result: The MDA concentration of normotensive, early PE and late PE were 0.147, 0.033 and 0.0155 consecutively. Kruskal Walis test showed a significant difference between MDA concentration in normotensive, early and late placenta (p < 0.001). In Mann Whitney test, normotensive placenta displayed a significantly higher MDA concentration than late-onset preeclampsia (p < 0.001). However, there were no significant difference between early & late-onset preeclampsia (p=0.133) ), and normotensive & early-onset preeclampsia (p = 0.011).

Conclusion: There is a decrease of ROS in late-onset PE indicated by lower lipid peroxidation level in PE than normal pregnancy. However, there is no difference of ROS between normotensive & early-onset PE, as the MDA concentration difference was not significant. These conditions may play role in the development of early and late preeclampsia among Indonesians."

"Salah satu tantangan berat dari kehadiran Internet of Things (IoT) adalah resource allocation. Hal itu terjadi karena terhubungnya node-node dalam jumlah banyak secara simultan ke dalam jaringan. Sedangkan bandwidth yang ada jumlahnya terbatas. Oleh sebab itu diperlukan algoritma penjadwalan yang efisien. Namun sayangnya, saat ini penelitian tentang network scheduling, terutama 802.15.4e, masih terkendala tools simulator. Berdasarkan penjelasan diatas penelitian ini mengusulkan platform simulator terbuka untuk mengimplementasikan network scheduling. Platform ini, dapat digunakan oleh siapa saja yang ingin melakukan simulasi algoritma penjadwalan. Platform ini dibangun menggunakan PHP dan javascript. Pada penelitian ini peneliti digunakan algoritma IR-TASA untuk menguji kinerja simulator yang dibangun. Hasilnya, pengujian pada dua variabel yaitu jumlah time slot aktif dan jumlah iterasi/cycle menunjukan hasil yang sama 100% antara network simulator dan pengujian heuristik, untuk percobaan menggunakan 10 topologi yang berbeda.

The most difficult challenge of the presence of the Internet of Things (IoT) is resource allocation. This happens because large numbers of nodes are simultaneously connected to networks, while the existing bandwidth is limited. Therefore, an efficient scheduling algorithm is needed. However, unfortunately, current research on network scheduling, especially 802.15.4e, is still constrained by simulator tools. Thus, this study proposes an open simulator platform for implementing network scheduling. This platform can be used by anyone who wishes to conduct a scheduling algorithm simulation. This platform is developed using PHP and javascript. In this study the researchers used the IR-TASA algorithm to test the performance of the proposed simulator. The results of testing from two variables the number of active time slots and the number of iterations/cyclesshowed the same result, 100%, between network simulators and heuristic testing, for experiments using 10 different topologies."

"Tingginya angka putus sekolah dan rendahnya tingkat partisipasi sekolah pada jenjang pendidikan yang lebih tinggi mengindikasikan rendahnya peluang keberlanjutan tingkat pendidikan. Hal itu akan berdampak pada kualitas modal manusia. Dalam hal ini, peningkatan kualitas modal manusia melalui pendidikan dapat dimulai dari anak sebagai generasi yang akan berperan dalam pembangunan di masa depan. Beberapa penelitian menemukan bahwa pendidikan berkaitan dengan bargaining power ibu. Namun, penelitian-penelitian sebelumnya menggunakan proxy tidak langsung bargaining power ibu. Penelitian ini bertujuan untuk memberikan bukti empiris mengenai adanya keterkaitan antara bargaining power ibu dalam rumah tangga dan keberlanjutan tingkat pendidikan anak dengan proxy langsung ukuran bargaining power ibu. Penelitian ini menggunakan informasi mengenai pengambilan keputusan rumah tangga dari data IFLS 2000-2014 sebagai ukuran bargaining power ibu. Berdasarkan hasil estimasi menggunakan metode probit, penelitian ini menunjukkan bahwa bargaining power ibu yang dilihat dari keterlibatan ibu dalam berbagai keputusan tidak berkaitan signifikan dengan keberlanjutan tingkat pendidikan anak. Namun, untuk keputusan yang lebih spesifik pada pendidikan anak, bargaining power ibu memiliki keterkaitan yang signifikan dan positif.

High dropout and low enrollment rates at higher levels of education indicate a low chance of continuing the level of education. It will have an impact on the quality of human capital. In this case, improving the quality of human capital through education can be initiated by children as a generation that will play a role in future development. Several studies have found that education is related to the mothers’ bargaining power. However, previous studies used an indirect proxy for the mothers' bargaining power. This study aims to provide empirical evidence regarding the relationship between the mothers' bargaining power in the household and the continuity of the children's education levels with a direct proxy for the mother's bargaining power. This study uses household decision-making information from IFLS 2000-2014 to measure the mothers' bargaining power. Based on the estimation results using the probit method, this study shows that the mother's bargaining power, as seen from the mother's involvement in various decisions, has no statistically significant relationship with the continuity of the children's education levels. However, for decisions more specific to children's education, the mother's bargaining power has a significant and positive relationship."
