AbstractWe consider the assignment problem between two sets of N random points on a smooth, two-dimensional manifold $$\Omega $$ Ω of unit area. It is known that the average cost scales as $$E_{\Omega }(N)\sim {1}/{2\pi }\ln N$$ E Ω ( N ) ∼ 1 / 2 π ln N with a correction that is at most of order $$\sqrt{\ln N\ln \ln N}$$ ln N ln ln N . In this paper, we show that, within the linearization approximation of the field-theoretical formulation of the problem, the first $$\Omega $$ Ω -dependent correction is on the constant term, and can be exactly computed from the spectrum of the Laplace–Beltrami operator on $$\Omega $$ Ω . We perform the explicit calculation of this constant for various families of surfaces, and compare our predictions with extensive numerics.

Breastfeeding Counseling

Background : Scaling Up Nutrition movement is a global effort to strengthen our commitment and accelerating action plan to improve nutrition, particularly the handling of nutrition in the first 1,000 days of life is exclusive breastfeeding and it until 24 months. One of the way is with exclusive breastfeeding counselling that can reduce stunting. The counseling is addressed to brides who need special attention in improving the nutrition and health. Objective : The aim of research to improve knowledge about exclusive breastfeeding counseling the bride through the use of leaflets. Method : This quasi-experimental study was a sample of 30 person a brides with non-random assignment, the variable a knowledge obtained through interviews using questionnaires while the method of counseling does face to face with an exclusive breastfeeding leaflet. The data was analyzed by dependent t-test. Result : The results showed exclusive breastfeeding counseling can improve knowledge bride (p= 0,000) with a mean difference is 6,13 and a deviation is 3,71. Conclusion : Increase of knowledge among ‘bride-to be’ about exclusive breastfeeding could be improved through the use of exclusive breastfeeding leaflet. Each health center must be in collaboration with Office of Religious Affairs to have exclusive breastfeeding counseling, and set one of the priority programs in the prevention of child stunting.   Keywords: Bride, counseling, knowledge of exclusive breastfeeding

Quasi Experiment

Penelitian ini bertujuan untuk: 1) mengetahui perbedaan hasil belajar antara mahasiswa yang diajarkan dengan Problem Based Learning dibanding mahasiswa yang diajarkan pembelajaran Group Investigation, 2) mengetahui peningkatan hasil belajar mahasiswa akibat penerapan pembelajaran Problem Based Learning. Jenis penelitian ini quasi experiment. Populasi penelitian adalah sebanyak 132 orang mahasiswa dilakukan secara random assignment. Teknik pengumpulan data menggunakan tes tertulis. Data yang diperoleh dianalisis dengan statistik deskriptif. Hasilnya sebagai berikut. 1) Terdapat perbedaan hasil belajar antara mahasiswa yang diajar Problem Based Learning dengan nilai rata-rata 75,00, nilai tertinggi 90 dan nilai terendah 55, dibandingkan mahasiswa yang diajar pembelajaran Group Investigation dengan nilai rata-rata 59,55, nilai tertinggi 75, dan nilai terendah 40. 2) Ada peningkatan hasil belajar mahasiswa akibat penerapan pembelajaran Problem Based Learning dengan nilai rata-rata peningkatan 46,11 dan ada peningkatan hasil belajar siswa dengan pembelajaran Group Investigation sebesar 29,20.
