Pengaruh Promosi Kesehatan Tentang Kehamilan Tidak Diinginkan Terhadap Tingkat Pengetahuan Dan Sikap Remaja Di Sma Sandika
Background: Adolescents at the age of 13-20 years begin to recognize the opposite sex and there is a desire to fulfill their sexual needs, so that it can cause unwanted pregnancy. The prevalence of unwanted pregnancies in the world in 2012 was 85%. So the need for health promotion in schools is necessary.
Objective: To determine the effect of health promotion on unwanted pregnancy on the level of knowledge and attitudes of adolescents at Sandika High School. Method: This study used the one group pretest-posttest design with Pre Experimental Design technique, the number of samples was 84 respondents with the Cluster Random Sampling technique. Bivariate analysis uses the Wilcoxon Test.
Results: The number of respondents was more than 17 years old 41 (48,8%), male gender 42 (50,0%) dan female 42 (50,0%) responden. Level of knowledge of adolescents before health promotion more knowledge level both 53 (63,1%) and after health promotion more the level of good knowledge as much as 73 (86,9%) respondents, more attitudes of adolescents before being given moderate attitude health promotion as many as 49 (58,3%) respondents and after being given health promotion more moderate attitudes as many as 64 (76,2 %) respondents. the influence of the level of knowledge before and after health promotion with a p value = 0.001, which means that there is an effect of health promotion about unwanted pregnancy on the level of knowledge of adolescents There are attitudinal influences before and after health promotion with p value = 0.001 which means there is an influence about unwanted pregnancy towards adolescent attitudes.
Suggestion: Hold collaboration with health centers in improving the system of adolescent reproductive system healt
Spin glasses on Bethe Lattices for large coordination number
We study spin glasses on random lattices with finite connectivity. In the
infinite connectivity limit they reduce to the Sherrington Kirkpatrick model.
In this paper we investigate the expansion around the high connectivity limit.
Within the replica symmetry breaking scheme at two steps, we compute the free
energy at the first order in the expansion in inverse powers of the average
connectivity (z), both for the fixed connectivity and for the fluctuating
connectivity random lattices. It is well known that the coefficient of the 1/z
correction for the free energy is divergent at low temperatures if computed in
the one step approximation. We find that this annoying divergence becomes much
smaller if computed in the framework of the more accurate two steps breaking.
Comparing the temperature dependance of the coefficients of this divergence in
the replica symmetric, one step and two steps replica symmetry breaking, we
conclude that this divergence is an artefact due to the use of a finite number
of steps of replica symmetry breaking. The 1/z expansion is well defined also
in the zero temperature limit.Comment: 17 pages and 6 figure
Pola interaksi masyarakat desa dengan tenaga kesehatan pada masa Covid-19 ( studi kasus di Desa Jaluk, Kecamatan Ketol, Kabupaten Aceh Tengah)
Penelitian ini mengkaji pola interaksi masyarakat desa dengan tenaga kesehatan pada masa Covid-19. Penelitian ini dilaksanakan di Desa Jaluk, Kecamatan Ketol, Kabupaten Aceh Tengah. Penelitian ini menggunakan metode kualitatif dengan diskriptif analisis. Teori yang digunakan dalam penelitian ini adalah teori aksi yang dikembangkan oleh Max Weber. Hasil penelitian menunjukkan bahwa pola interaksi masyarakat terjalin dikarenakan tindakan aksi, pengalaman, pengetahuan, tindakan rasional, dan nilai dalam masyarakat desa. Pola interaksi yang terjalin antara masyarakat dan tenaga kesehatan yaitu: Interaksi dalam kegiatan penyuluhan, Interaksi dalam kerjasama penanggulangan covid-19, interaksi dengan prosedur prokes, kepercayaan terhadap tenaga kesehatan di desa, interaksi dalam kecurigaan dengan tenaga kesehatan. Sedangkan alasan masyarakat mengizinkan tenaga kesehatan kembali ke desa karena sifat kekeluargaan yang masih tinggi dikalangan masyarakat, kepercayaan terhadap tenaga kesehatan serta kebutuhan masyarakat kepada tenaga kesehatan.
A minimal stochastic model for influenza evolution
We introduce and discuss a minimal individual-based model for influenza
dynamics. The model takes into account the effects of specific immunization
against viral strains, but also infectivity randomness and the presence of a
short-lived strain transcending immunity recently suggested in the literature.
We show by simulations that the resulting model exhibits substitution of viral
strains along the years, but that their divergence remains bounded. We also
show that dropping any of these features results in a drastically different
behavior, leading either to the extinction of the disease, to the proliferation
of the viral strains, or to their divergence
Maximum entropy models capture melodic styles
We introduce a Maximum Entropy model able to capture the statistics of
melodies in music. The model can be used to generate new melodies that emulate
the style of the musical corpus which was used to train it. Instead of using
the body interactions of order Markov models, traditionally used in
automatic music generation, we use a nearest neighbour model with pairwise
interactions only. In that way, we keep the number of parameters low and avoid
over-fitting problems typical of Markov models. We show that long-range musical
phrases don't need to be explicitly enforced using high-order Markov
interactions, but can instead emerge from multiple, competing, pairwise
interactions. We validate our Maximum Entropy model by contrasting how much the
generated sequences capture the style of the original corpus without
plagiarizing it. To this end we use a data-compression approach to discriminate
the levels of borrowing and innovation featured by the artificial sequences.
The results show that our modelling scheme outperforms both fixed-order and
variable-order Markov models. This shows that, despite being based only on
pairwise interactions, this Maximum Entropy scheme opens the possibility to
generate musically sensible alterations of the original phrases, providing a
way to generate innovation
Dynamical correlations in the escape strategy of Influenza A virus
The evolutionary dynamics of human Influenza A virus presents a challenging
theoretical problem. An extremely high mutation rate allows the virus to
escape, at each epidemic season, the host immune protection elicited by
previous infections. At the same time, at each given epidemic season a single
quasi-species, that is a set of closely related strains, is observed. A
non-trivial relation between the genetic (i.e., at the sequence level) and the
antigenic (i.e., related to the host immune response) distances can shed light
into this puzzle. In this paper we introduce a model in which, in accordance
with experimental observations, a simple interaction rule based on spatial
correlations among point mutations dynamically defines an immunity space in the
space of sequences. We investigate the static and dynamic structure of this
space and we discuss how it affects the dynamics of the virus-host interaction.
Interestingly we observe a staggered time structure in the virus evolution as
in the real Influenza evolutionary dynamics.Comment: 14 pages, 5 figures; main paper for the supplementary info in
