The study examines job stress, job satisfaction, physical health, work accidents and faulty work. Study was involving 100 aircraft technicians PT. Merpati Nusantara Airlines. Occupational injuries is measured by Safety Related Injuries Scale. Work was measured with a scale error faulty work by the job description of aircraft maintenance division that has been standard. Physical health was measured by Physical Health Questionnaire (PHQ). Job satisfaction was measured by job satisfaction scale developed by researchers. Work stress was measured by Job Stress Survey (JSS). Data occupational accidents, faulty work, physical health, job satisfaction and job stress were analyzed with statistical regression analysis. The analysis showed job stress did not predict an increase in accidents and faulty work. Job stress did not predict decline in physical health and job satisfaction. High and low occupational accidents, faulty work, physical health, and aircraft technician job satisfaction can not be predicted through the high and low job stress
Hubungan Antara Penggunaan Internet Dengan Prestasi Belajar
The background of this research is the adolescence as internet user. If internet is used to something that have complication with study, it can be opinioned have positive relation with academic achievement, but, if internet is used to something that haven't complication with study, it can be opinioned have negative relation with academic achievement. Use of internet is as an information, communication, leisure, financial transaction, and education. This study present data from rapport and survey of 140 students at GIKI 2 elementary high school. The result showed that there was not relationships between use of internet as an information, communication, leisure, financial transaction and education with academic achievement [R=0,246; R2=0,061; F=0,734; p=0,130 (p > 0, 05)], this case showed that the result is not significant. It can be concluded that the use of internet cannot be increased or decrease academic achievement
Deoxyfluorination tunes the aggregation of cellulose and chitin oligosaccharides and highlights the role of specific hydroxyl groups in the crystallization process
Cellulose and chitin are abundant structural polysaccharides exploited by nature in a large number of applications thanks to their crystallinity. Chemical modifications are commonly employed to tune polysaccharide physical and mechanical properties, but generate heterogeneous mixtures. Thus, the effect of such modifications is not well understood at the molecular level. In this work, we examined how deoxyfluorination (site and pattern) impact the solubility and aggregation of well-defined cellulose and chitin oligomers. While deoxyfluorination increased solubility in water and lowered the crystallinity of cellulose oligomers, chitin was much less affected by the modification. The OH/F substitution also highlighted the role of specific hydroxyl groups in the crystallization process. This work provides guidelines for the design of cellulose- and chitin-based materials. A similar approach can be imagined to prepare cellulose and chitin analogues capable of withstanding enzymatic degradation
Association between serum level of vitamin D and lipid profiles in type 2 diabetic patients in Iran
Background: It is suggested that vitamin D deficiency is associated with cardiovascular disease (CVD) via its effect on lipid profiles. The objective of this study was to determine the association between fasting serum levels of 25(OH) D and lipid profiles in patients with type 2 diabetes.Methods: This cross-sectional study was conducted on 108 type 2 diabetics. Patients were selected randomly among members of the Iranian Diabetes Association according to study criteria. Fasting concentration of 25(OH) D, calcium, phosphorus, parathyroid hormone (PTH) and lipid profiles (including triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and total cholesterol) were measured.Results: The mean serum levels of 25-hydroxyvitamin D (25(OH) D) and PTH were 53.41 ± 33.25 nmol/l and 40.24 ± 18.24 pmol/l, respectively, in type 2 diabetic patients. Prevalence of vitamin D deficiency was 58.34 and vitamin D sufficiency and insufficiency combined was 41.66. Although in diabetic patients with vitamin D deficiency, serum levels of total cholesterol, TG, and LDL were higher and HDL was lower compared to patients with vitamin D sufficiency, this association was statistically significant only for serum level of TG (145.91 ± 79.00 vs. 122.95 ± 55.82 mg/dl).Conclusions: The results of present study show that serum concentrations of 25(OH) D were inversely associated with TG. More interventional studies are needed to confirm the relationship between serum concentration of vitamin D and lipid profile in patients with type 2 diabetes. © 2014 Saedisomeolia et al.; licensee BioMed Central Ltd
Problems of methodological determination of the place of financial and budgetary control in the system of state financial control
The relevance of this report due to the presence of problems in the field of budgetary control at all levels of the Russian budget system, which leads to numerous cases of misuse and inefficient use of budget funds and other public property, overestimation of the cost of purchased goods, works and services for state and municipal needs, the use of other corruption schemes in the budget mechanism
Projectile and target-Roper excitation in the p (d, d')X reaction
In this paper we compare a model that contains the mechanisms of
excitation in the projectile and Roper excitation in the target with
experimental data from two (d, d') experiments on a proton target. The
agreement of the theory with the experiment is fair for the data taken at T_d =
2.3 GeV. The excitation in the projectile is predicted close to the
observed energy with the correct width. The theory, however, underpredicts by
about 40% the cross sections measured at T_d = 1.6 GeV at angles where the
cross section has fallen by about two orders of magnitude. The analysis done
here allows to extract an approximate strength for the excitation of the Roper
[N^*(1440)] excitation and a qualitative agreement with the theoretical
predictions is also found.Comment: 8 ps figure
Polarization transfer in the O reaction at forward angles and structure of the spin-dipole resonances
Cross sections and polarization transfer observables in the O
reactions at 392 MeV were measured at several angles between
0 and 14. The non-spin-flip () and spin-flip
() strengths in transitions to several discrete states and broad
resonances in O were extracted using a model-independent method. The
giant resonances in the energy region of 27 MeV were found to be
predominantly excited by transitions. The strength distribution
of spin-dipole transitions with and were deduced.
The obtained distribution was compared with a recent shell model calculation.
Experimental results are reasonably explained by distorted-wave impulse
approximation calculations with the shell model wave functions.Comment: 28 pages RevTex, including 9 figures, to be published in Phys. Rev.

Thin Ice Target for O(p,p') experiment
A windowless and self-supporting ice target is described. An ice sheet with a
thickness of 29.7 mg/cm cooled by liquid nitrogen was placed at the target
position of a magnetic spectrometer and worked stably in the O
experiment at MeV. Background-free spectra were obtained.Comment: 14 pages, 4 figures, Nucl. Instr. & Meth. A (in press
