Perception of Community Health Workers in Indonesia Toward Patients with Mental Disorders
In Indonesia, there are any community health volunteers called Kader. Although Kaders are members of mental health volunteer, they sometimes show negative attitude to psychotic persons, even they have already got some training about mental health. The aims of this study were to investigate 1) how is Kader's perception compare to the other countries, 2) how will they consult compare to the other countries 3) how is comparison of Kaders' perception to mental disorder person between trained and untrained. The method of this research is a descriptive explorative using survey study. This study was held on June to September 2013. It was conducted in five districts of Yogyakarta area with 619 respondents. The Questionnaires used contained three sections are follows; Part A is about Demographic Data, Part B two case vignettes (taken from MacArthur Health Module of the 1996 general Social Survey) and Part C about Kaders experiences. The perception of Kader as part of the community is lower than the general residence in the United States and Japan. The comparison between trained and untrained Kaders shown that trained Kaders has better perception toward patient with mental disorder. These results suggest that actual experiences in meeting the cases contributed to the improvement of Kaders' perception better than the previous mental health training did. It might be Kaders with short experience are explored information Kaders should be trained with more structured curriculum and recruiting Kader is recommended to recruit the young generation
The Effect of Poloidal Magnetic Field on Type I Planetary Migration: Significance of Magnetic Resonance
We study the effect of poloidal magnetic field on type I planetary migration
by linear perturbation analysis in the shearing-sheet approximation and the
analytic results are compared with numerical calculations. In contrast to the
unmagnetized case, the basic equations that describe the wake due to the planet
in the disk allow magnetic resonances at which density perturbation diverges.
In order to simplify the problem, we consider the case without
magneto-rotational instability. We perform two sets of analyses:
two-dimensional and three-dimensional. In two-dimensional analysis, we find the
generalization of the torque formula previously known in unmagnetized case. In
three-dimensional calculations, we focus on the disk with very strong magnetic
field and derive a new analytic formula for the torque exerted on the planet.
We find that when Alfven velocity is much larger than sound speed,
two-dimensional torque is suppressed and three-dimensional modes dominate, in
contrast to the unmagnetized case.Comment: 33 pages, 10 figures, typos corrected, discussion added, reference

Stability of quantum states of finite macroscopic systems against classical noises, perturbations from environments, and local measurements
We study the stability of quantum states of macroscopic systems of finite
volume V, against weak classical noises (WCNs), weak perturbations from
environments (WPEs), and local measurements (LMs). We say that a pure state is
`fragile' if its decoherence rate is anomalously great, and `stable against
LMs' if the result of a LM is not affected by another LM at a distant point. By
making full use of the locality and huge degrees of freedom, we show the
following: (i) If square fluctuation of every additive operator is O(V) or less
for a pure state, then it is not fragile in any WCNs or WPEs. (ii) If square
fluctuations of some additive operators are O(V^2) for a pure state, then it is
fragile in some WCNs or WPEs. (iii) If a state (pure or mixed) has the `cluster
property,' then it is stable against LMs, and vice versa. These results have
many applications, among which we discuss the mechanism of symmetry breaking in
finite systems.Comment: 6 pages, no figure.Proof of the theorem is described in the revised

Light Higgs boson scenario in the SUSY seesaw model
It is demonstrated that the light Higgs boson scenario, which the lightest
Higgs mass is less than the LEP bound, mh > 114.4 GeV, is consistent with the
SUSY seesaw model. With the assumptions of the universal right-handed neutrino
mass and the hierarchical mass spectrum of the ordinary neutrinos, the bounds
for the right-handed neutrino mass is investigated in terms of lepton flavor
violating charged lepton decays. We also discuss the effect of the modification
of renormalization group equations by the right-handed neutrinos on the b to s
gamma process and the relic abundance of dark matter in the light Higgs boson
scenario.Comment: 17 pages, 5 figure
New reductions of integrable matrix PDEs: -invariant systems
We propose a new type of reduction for integrable systems of coupled matrix
PDEs; this reduction equates one matrix variable with the transposition of
another multiplied by an antisymmetric constant matrix. Via this reduction, we
obtain a new integrable system of coupled derivative mKdV equations and a new
integrable variant of the massive Thirring model, in addition to the already
known systems. We also discuss integrable semi-discretizations of the obtained
systems and present new soliton solutions to both continuous and semi-discrete
systems. As a by-product, a new integrable semi-discretization of the Manakov
model (self-focusing vector NLS equation) is obtained.Comment: 33 pages; (v4) to appear in JMP; This paper states clearly that the
elementary function solutions of (a vector/matrix generalization of) the
derivative NLS equation can be expressed as the partial -derivatives of
elementary functions. Explicit soliton solutions are given in the author's

Slow decay of dynamical correlation functions for nonequilibrium quantum states
A property of dynamical correlation functions for nonequilibrium states is
discussed. We consider arbitrary dimensional quantum spin systems with local
interaction and translationally invariant states with nonvanishing current over
them. A correlation function between local charge and local Hamiltonian at
different spacetime points is shown to exhibit slow decay.Comment: typos correcte
