Long Term Follow Up

Studies have investigated the applications of Continuous Positive Airway Pressure (CPAP) therapy in the treatment of hypernasality due to velopharyngeal dysfunction (VPD; Cahill et al., 2004; Kuehn, 1991; Kuehn, Moon, & Folkins, 1993; Kuehn et al., 2002). The purpose of this study was to examine the effectiveness of CPAP therapy to reduce hypernasality in a female subject, post-traumatic brain injury (TBI) and pharyngeal flap, who presented with signs of VPD including persistent hypernasality. Improvements in mean velopharyngeal orifice size, subjective perception of hypernasality, and overall intelligibility were observed from the baseline to 8-week post-treatment assessment intervals. Additional long-term assessments completed at 2, 3, and 4 months post-treatment indicated decreases in immediate post-treatment improvements. Results from the present study suggest that CPAP is a safe, non-invasive, and relatively conservative treatment method for reduction of hypernasality in selected patients with TBI. More stringent long-term follow up may indicate the need for repeated CPAP treatment to maintain results.

Descriptive Approach

Schizophrenia adalah gangguan jiwa berat ditandai dengan perubahan pada persepsi, pikiran, afek, dan perilaku seseorang. Gejala schizophrenia berlangsung selama jangka waktu minimum  satu  bulan dan kemunduran  fungsi  berlangsung minimum selama enam bulan dengan tingkat kekambuhan 70 - 82%. Penderita schizophrenia sering ditemukan kurang mendapat dukungan sosial dalam mengoptimalkan proses rehabilitasi setelah menjalani perawatan di Rumah Sakit. Tujuan studi untuk mengekplorasi pengalaman survivor schizophrenia beradaptasi pasca rawat. Metode penelitian kualitatif dengan pendekatan deskriptif fenomenologi terhadap 10  informan. Hasil  ditemukan 5 tema adaptasi pasca perawatan di rumah sakit yaitu cara menghadapi suatu permasalahan, memiliki pekerjaan setelah keluar dari rumah sakit jiwa, dukungan keluarga, dukungan lingkungan dan dukungan tenaga kesehatan. Kesimpulan adaptasi survivor schizophrenia pasca perawatan di rumah sakit  membutuhkan kemampuan problem solving, dukungan dari keluarga dan masyarakat. Kata kunci: adaptasi, pengalaman, schizophrenia, survivor THE EXPERIENCE OF SCHIZOPHRENIA SURVIVOR ADAPTATION POST-CARE IN HOSPITAL    ABSTRACTSchizophrenia is a severe mental disorder characterized by changes in a person's perceptions, thoughts, affect, and behaviour. Schizophrenia symptoms last for a minimum period of one month and deterioration of function lasts for a minimum of six months with a recurrence rate of 70 - 82%. Schizophrenia sufferers are often found to lack social support in optimizing the rehabilitation process after undergoing treatment at the hospital. Purpose to explore the experience of survivor schizophrenia adapting post-treatment. Method Qualitative with a phenomenological descriptive approach to 10 informants. Results found 5 adaptation post-treatment themes in the hospital namely how to deal with a problem, having a job after leaving the mental hospital, family support, environmental support and support of health workers. Conclusion: Adaptation of post-treatment schizophrenia survivors in hospital requires problem- solving skills, support from family and community.  Keywords: adaptation, experience, schizophrenia, survivor

This research focused on the influence of post-treatment using alkali-catalyzed hydrolysis with a full-aromatic nanofiltration (NF) polyamide membrane and its application to the efficient removal of selected dyes. The post-treated membranes were characterized through Fourier transform infrared spectroscopy, goniometry, and zeta-potential analysis to analyze the treatment-induced changes in the intrinsic properties of the membrane. Furthermore, the changes in permeability induced by the post-treatment were evaluated via the measurement of water flux, NaCl rejection, and molecular weight cutoff (MWCO) under different pH conditions and post-treatment times. Major changes induced by the post-treatment in terms of physicochemical properties were the enhancement of permeability, hydrophilicity, and negative charge due to the hydrolysis of the membrane’s amide bonds. Four different dyes were selected as representative organic pollutants considering the MWCO of the post-treated membranes. Compared with the pristine NF membrane, membranes post-treated at pH 13.5 showed better water flux with similar rejection of the target dyes. On the basis of these results, the proposed post-treatment method for NF membranes can be applied to the removal of organic pollutants of various size.

This paper provides a novel post treatment method to achieve high conductivity of nano-size silver coatings. Based on the preparation of nano-size conductive ink and conductive circuit, the printed sample and the coated conductive film were treated by series concentrations of silver nitrate solution and hydrazine hydrate solution in this order. The samples were dipped in 1%~20% solutions of silver nitrate and hydrazine hydrate successively, to form the new conductive layer of Ag particles only. It was investigated that the relationship between the thickness of printed and coated layers on photo paper and final conductivity after dipped in two kinds of solutions in turn, which were printed from one to three times and coated by screw (6#). Atomic force microscopy (AFM) was used to characterize the morphologies of as printed and coated samples. The surface sheet resistance of sample was tested by four-probe tester. It was found that when the coated silver conductive ink samples were dipped in 2% silver nitrate solutions and 2% hydrazine hydrate solution at room temperature, the conductivity reaches 0.82Ω/□. The samples with thicker conductive film before dipping need solutions at lower concentration to get high conductivity. The roughness of samples after treatment falls down, as the concentrate of dipping solutions rising. It is therefore considered that the “dip in” method provides an efficient alternative to improve the conductivity of samples.
