Improving Breeding Efficiency of a Hybrid Maize Breeding Program Using a Three Heterotic‐Group Classification
Authors: Fan XingMing , Bi Yaqi , Zhang Yudong , Jeffers Daniel , Yin XingFu , Kang Manjit
Published: April 2018

Core Ideas

Maize breeding efficiency can be greatly improved by adopting three heterotic groups in hybrid breeding.

Using three heterotic groups improves maize breeding efficiency for using genetic resources.

General breeding efficiency is used to measure efficiency of genetic resource usage, and specific breeding efficiency is to obtain maximum output with inputs.

Suwan1 is an important heterotic group from tropical/subtropical and should be explore more worldwide.

Heterotic group classification has a crucial impact on maize (Zea mays L.) breeding efficiency in a hybrid‐based breeding program. The objectives of this study were to: (i) investigate whether or not breeding efficiency could be improved using a three heterotic‐group (TriHG) classification (Reid and non‐Reid, and Suwan1 heterotic groups) system instead of a usual two heterotic‐group (DiHG) classification (Reid and non‐Reid heterotic groups) system; and (ii) estimate the impact of TriHG and DiHG systems on breeding efficiency, utilizing the same data in computing specific breeding efficiency (SBE) and general breeding efficiency (GBE) in a subtropical breeding program in southern China. Twenty‐five adapted tropical and subtropical lines were crossed to six testers using a line × tester mating design. Data on grain yield were used to calculate SBE and GBE for comparing DiHG‐ and TriHG‐based strategies. The TriHG classification system increased GBE by 77.8% over the DiHG system without a significant loss in SBE. We concluded that the TriHG system was better than the DiHG system for improving maize‐breeding efficiency. Therefore, maize breeders may re‐think their breeding strategy for improving breeding efficiency in long‐term breeding programs by adopting the suggested TriHG system. Hybrid maize improvement programs, especially in the early stages of breeding for identifying hybrids with high yield potential, can be become more efficient by using three testers with one from each of Reid, nonReid, and Suwan1 heterotic groups. This would improve the chances of developing high‐yielding hybrids in a breeding program with the available, diverse germplasm.
Spatial Patterns of Escherichia coli Concentrations in Sediment before and after High‐Flow Events in a First‐Order Creek
Authors: Stocker Matthew D. , Penrose Michael , Pachepsky Yakov A.
Published: April 2018

Understanding spatial patterns of Escherichia coli in freshwater sediments is necessary to characterize sediments as microbial reservoirs and to evaluate the impact of sediment resuspension on microbial water quality in watersheds. Sediment particle size distributions and streambed E. coli concentrations were measured along a 500‐m‐long reach of a first‐order creek 1 d before and on Days 1, 3, 6, and 10 after each of two artificial high‐flow events, with natural high‐flow events also occurring within the sampling periods. Spatial variability of E. coli was greater in sediments than in water within any given sampling; however, variation between sampling days was greater for water than for sediment. The mean relative difference analysis revealed temporally stable patterns of E. coli concentrations in sediments. Escherichia coli–rich locations along the reach corresponded to areas with higher organic matter and fine particle contents. Although low (k < 0.5 d−1) or negative survival rates were observed at most locations along the reach during times where no precipitation was recorded, a small number of locations showed such large concentration increase that on average the survival rate remained positive at the reach scale. The studied creek appears to have hot spots of concentration increase, where conditions for E. coli populations to increase are much more favorable than in most other locations across the reach. The effect of this increase can be seen at the reach scale but is difficult to discern without individual sampling that is dense in space and time.

Core Ideas

Temporally stable patterns of E. coli concentrations in sediments were observed.

Reach‐average E. coli concentrations increased in sediments between high‐flow events.

E. coli survival rates were generally low except in certain locations along the reach.
Soil Drought and Water Carrying Capacity for Vegetation in the Critical Zone of the Loess Plateau: A Review
Authors: Shao Ming'an , Wang Yunqiang , Xia Yongqiu , Jia Xiaoxu
Published: April 2018

Core Ideas

The progress of research on soil drought in the Loess Plateau was reviewed.

Spatiotemporal patterns of dried soil layers were scale dependent.

SWCCV was recommended for optimizing water management in the critical zone of the LP.

The Loess Plateau (LP) of China is a good representative area for critical zone (CZ) science studies. The LP is famous for its deep loess. In most areas, the thickness of the loess profile is deeper than 100 m, and two‐thirds of the area is arid and semiarid. With the Grain‐for‐Green project, the vegetation of the plateau has recovered gradually. However, with the increase in vegetative coverage, especially the planted vegetation, the water content of the soil profile has decreased and the soil is much drier. In this review, particular emphasis is paid to the dry conditions of deep soil, drought, regional restoration of vegetation, and effective management of soil moisture. We reviewed the progress of research on dried soil layers (DSLs) that resulted from soil drought in the past decades on the Plateau, and then we summarized the development of the concept and models of soil water carrying capacity for vegetation (SWCCV). This review is helpful for understanding the development of DSLs, optimizing soil water management through vegetation mediation, and designing a long‐term sustainable framework for water‐limited ecosystems.
Hydropedological Interpretation of Regional Soil Information to Conceptualize Groundwater–Surface Water Interactions
Authors: van Tol Johan J. , Lorentz Simon A.
Published: April 2018

Core Ideas

Hydropedology can serve as an indicator of the hydrological behavior of catchments.

Hydropedological interpretations are applicable at regional scales.

Internal catchment properties are often more important than environmental factors.

Understanding and quantifying groundwater–surface water interactions is important for effective water resource management. Characterization of these interactions is difficult due to heterogeneities in landscapes and difficulties in measuring hydrological processes at different scales. Although soils play an integral role in the hydrological functioning of landscapes, very few groundwater–surface water interaction studies consider soils as key components of hydrologic variation. We studied 21 catchments in South Africa with available stream attributes, such as baseflow index (BFI) and hydrological variability (CVB). The soils of the catchments were interpreted and grouped into four classes based on dominant hydropedological response: Recharge, Interflow, Responsive (shallow), and Responsive (wet). The dominant soil distribution patterns in the catchments were then determined. Significant positive Spearman correlation coefficients exist between BFI and soil attributes such as depth (0.72), clay content (0.54), and the area covered by Recharge soils (0.81). The occurrence of Interflow and shallow soils is inversely correlated to BFI (−0.86 and −0.67, respectively), whereas CVB was positively correlated to the area of Interflow soils (0.81) and negatively to the area of Recharge soils (−0.75). Based on the hydropedological soil distribution pattern, three conceptual models of groundwater–surface water interactions were constructed: (i) those where vertical drainage and recharge of groundwater in the upper slopes are dominant, with return flow to soil layers in lower‐lying positions, and soil and groundwater contribute to streamflow; (ii) those where vertical drainage through soils and recharge of groundwater is dominant in upper and lower lying landscape positions, there is no return flow to soils, and only groundwater contributes to streamflow; and (iii) those where lateral flow at the soil–bedrock interface is dominant throughout the catchment, limited recharge occurs, and the stream is fed through lateral flow from soils with limited contribution from groundwater.
Development of a Physically Based Soil Albedo Parameterization for the Tibetan Plateau
Authors: Zheng Guanheng , Yang Hanbo , Lei Huimin , Yang Dawen , Wang Taihua , Qin Yue
Published: April 2018

Core Ideas

Liquid soil moisture controls seasonal variations in soil albedo.

Solar zenith angle determines diurnal variations in soil albedo.

Soil optical parameter values can be reasonably estimated from soil composition.

The simulated surface energy budget in summer is considerably improved.

Soil albedo controls the surface energy budget on the Tibetan Plateau (TP); however, estimates of the soil albedo include substantial uncertainties. This study presents a physically based soil albedo parameterization that includes the effects of the solar zenith angle and liquid soil moisture. The parameter values are calibrated and validated using the measurements from the Global Energy and Water Cycle Experiment–Asian Monsoon Experiment and the Coordinated Enhanced Observing Period Asia–Australia Monsoon Project (CAMP‐Tibet). Because few measurements of albedo are available from the TP, a transfer equation was built to estimate the parameter values through their inverse physical links with the soil composition. Compared with previous parameterizations, the parameter values from the transfer equation reduce the simulated mean bias and RMSE values by nearly 50%. Comparisons of the observed albedos and simulated values obtained using the new parameterization show that the correlation values are >0.5 and that the absolute errors (dimensionless) are within ±0.05. The new parameterization captures the diurnal and seasonal variations better than the previous schemes and shows that the diurnal and seasonal variations in soil albedo are controlled by the solar zenith angle and liquid soil moisture, respectively. This new parameterization scheme was incorporated into the Geomorphology‐Based Eco‐Hydrological Model and run for the CAMP‐Tibet stations. The inclusion of this new parameterization significantly improved the simulated surface energy budget in summer; the deviations in the upward shortwave radiation decreased by 81%, and the accuracy of the simulated Bowen ratio increased substantially.
Imidacloprid Sorption and Transport in Cropland, Grass Buffer, and Riparian Buffer Soils
Authors: Satkowski Laura E. , Goyne Keith W. , Anderson Stephen H. , Lerch Robert N. , Webb Elisabeth B. , Snow Daniel D.
Published: April 2018

Core Ideas

Vegetative buffer strip (VBS) soils sorb imidacloprid (ICD) more than cropland soils due to greater SOC.

Riparian VBS soils retard ICD leaching more than cropland and grass VBS soils.

Results indicate ICD sorption to two or three sites, likely through different mechanisms.

A VBS may reduce the mobility of ICD in agroecosystems.

An understanding of neonicotinoid sorption and transport in soil is critical for determining and mitigating environmental risk associated with the most widely used class of insecticides. The objective of this study was to evaluate mobility and transport of the neonicotinoid imidacloprid (ICD) in soils collected from cropland, grass vegetative buffer strip (VBS), and riparian VBS soils. Soils were collected at six randomly chosen sites within grids that encompassed all three land uses. Single‐point equilibrium batch sorption experiments were conducted using radio‐labeled (14C) ICD to determine solid–solution partition coefficients (Kd). Column experiments were conducted using soils collected from the three vegetation treatments at one site by packing soil into glass columns. Water flow was characterized by applying Br− as a nonreactive tracer. A single pulse of 14C‐ICD was then applied, and ICD leaching was monitored for up to 45 d. Bromide and ICD breakthrough curves for each column were simulated using CXTFIT and HYDRUS‐1D models. Sorption results indicated that ICD sorbs more strongly to riparian VBS (Kd = 22.6 L kg−1) than crop (Kd = 11.3 L kg−1) soils. Soil organic C was the strongest predictor of ICD sorption (p < 0.0001). The column transport study found mean peak concentrations of ICD at 5.83, 10.84, and 23.8 pore volumes for crop, grass VBS, and riparian VBS soils, respectively. HYDRUS‐1D results indicated that the two‐site, one‐rate linear reversible model best described results of the breakthrough curves, indicating the complexity of ICD sorption and demonstrating its mobility in soil. Greater sorption and longer retention by the grass and riparian VBS soils than the cropland soil suggests that VBS may be a viable means to mitigate ICD loss from agroecosystems, thereby preventing ICD transport into surface water, groundwater, or drinking water resources.
Strength and Permeability of Cultivated Histosols Characterized by Differing Degrees of Decomposition
Authors: Dessureault-Rompré Jacynthe , Thériault Laura , Guedessou Cédrick-Victoir , Caron Jean
Published: April 2018

Core Ideas

Cultivated organic soils (Histosols) are highly productive but very sensitive to degradation and compaction.

Penetration resistance and saturated hydraulic conductivity are two important parameters related to the degree of decomposition of Histosols.

Penetration resistance could be used to assess the depth of the compact layer, as well as the degree of decomposition, of Histosols.

Cultivated organic soils (Histosols) are an important part of the agricultural economy in Canada. However, problems of degradation and compaction affect this particular type of soil. The objective of this study was to characterize the soil penetration resistance and the saturated hydraulic conductivity (ksat) in cultivated organic soils that differed in their degree of decomposition. Three fields in the plain of Montreal, in southwestern Quebec, were selected to provide a gradient of degrees of decomposition. Site 1 was classified as a Limnic Fibrisol, Site 2 was classified as a Terric Mesic Humisol, and Site 3 was classified as a Terric Humisol. At each site, penetration resistance and ksat were measured directly in the field. Penetration resistance, particularly at the 25‐cm depth and deeper, was found to increase with increasing soil degradation. An inverse relationship was observed for ksat in the compact layer. The results presented in this study indicate that penetration resistance and ksat are both linked to the degree of soil decomposition. However, the relationship between both parameters is complex, and both parameters are to be measured to achieve a more accurate characterization of organic soils. Further work could assess the depth of the compact layer, as well as the degree of decomposition of organic soils at different spatial scales using penetration resistance. In Histosols, accurately mapping ksat would help in designing field drainage system, as this soil property is difficult to predict from other parameters.
Correcting for Biogenic Gas Matrix Effects on Laser‐Based Pore Water‐Vapor Stable Isotope Measurements
Authors: Gralher Benjamin , Herbstritt Barbara , Weiler Markus , Wassenaar Leonard I. , Stumpp Christine
Published: April 2018

Core Ideas

Observed biases were gas matrix effects exclusively caused by biogenic headspace CO2.

Observed biases exceeded 30× (δ2H) and 65× (δ18O) accepted measurement uncertainties.

The proposed correction scheme uses data from repeated analyses of soil samples only.

Post‐correction quality of isotope data matches accepted measurement uncertainties.

The presented method helps to avoid grave misinterpretations of soil water isotope data.

The isotopic composition (δ2H, δ18O) of pore water is an invaluable tracer for the minimally invasive study of subsurface water flow and transport processes. Here, we evaluated a method for pore water isotope analysis that combines laser‐based isotope analyzers and water‐vapor isotope equilibration using evaporation‐proof metalized sample bags. We tested inflation atmospheres (dry air vs. pure N2) and the impact of biogenic gas (CO2, CH4) accumulation for storage times of up to 4 wk. Samples were analyzed with a water isotope analyzer (Picarro L2120‐i) and a gas chromatograph. Air‐inflated water vapor samples showed a greater range of gas matrix effects (δ18O: 9.63‰; δ2H: 21.7‰) than N2–inflated samples (δ18O: 7.49‰; δ2H: 10.6‰) induced by nonuniform buildup of biogenic CO2, starting immediately after sample preparation. However, only air‐inflated samples could be reliably corrected using instrument‐specific sensitivity factors that were empirically determined by interpretation of periodically repeated isotope measurements. Corrected water isotope data were confirmed by similarity with local precipitation and suction cup isotope data. Residual uncertainties were well below the natural variations of soil water isotope values and independent of storage time, thus allowing for consistently reliable interpretations of soil water isotope profiles. We conclude that, especially for pore water sampling that requires small sample volumes and/or long storage times, metalized sample bags should be used to prevent evaporation notwithstanding the enhanced buildup of biogenic gases. Further, if gas matrix effects cannot be excluded, air inflation is preferred over pure N2, as only in that case can reliable postcorrections be performed by using internal data only.

Authors: Shu Hengtao , Yuan Hongwei
Published: April 2018

As complex axial flow machinery, lots of vortex distributes around engine cooling fan. Negative circumferential vorticity (CV) leads to low efficiency and power loss. In order to investigate the adverse effects of CV on aerodynamic performances of the fan, a mathematical physical relationship between CV and aerodynamic performances is established, and the location of the negative CV is found by the method of vorticity analysis. An outer ring is designed for annular cooling fan, and the parameter of aperture rate is defined in this paper. Both static pressure and power loss is overall considerate during the optimization process of the outer ring, and putting forward that optimum range of the aperture rate is different for various annular fans.
The effect of non-linear inertia on dynamic response of asymmetric multi-story buildings
Authors: Rezazadeh Hassan , Amini Fereidoun
Published: April 2018

The goal of this paper is to inspect the influence of non-linear inertia on dynamic response of multi-story asymmetric buildings. In this study unlike conventional linear approach, the non-linear inertial terms are considered in the equations of motion. For considering non-linear inertia, the motion equations are derived in local rotary coordinates system. Also, the stiffness and damping parameters are defined in the rotary coordinates system. In the novel approach which is proposed in this paper, the motion equations are different with conventional linear approach. Numerical examples are presented to compare the response of the proposed model and conventional linear model. The modeled building response is derived under harmonic excitation. The results show that if non-linear inertia is considered, the dynamic response of asymmetric multi-story buildings may become different with conventional linear approach.

A novel approach to quantifying elemental sulfur (S0) in environmental samples
Authors: Wang Yu , Zan Feixiang , Guo Gang , Hao Tianwei , Wang Jing , Chen Guanghao
Published: April 2018

The quantification of elemental sulfur (S0) is an important part of monitoring and controlling sulfur-involving processes. Existing methods of S0 detection either require significant time or involve the use of toxic chemicals. We have developed and validated a new method to determine S0 in environmental samples using calorimeter-ion chromatography (IC), in which S0 is fully oxidized to sulfur trioxide (SO3) with pure oxygen at 20 atm in a calorimeter. The resulting SO3 is then absorbed by a sodium bicarbonate (NaHCO3) solution and analyzed using IC. To verify this method, standard samples with various sulfur contents (5–200 mg S), possible interfering substances (SO42−, SO32−, S2O32− and S2−), and mixed environmental samples were tested and compared. The high correlation of R2 = 0.999 between the examined and theoretical values was obtained with a high recovery rate of ≥95% and a low relative standard deviation (RSD) of ≤1%. Samples containing at least 25 mg of S0 were accurately measured (recovery error < 5%). Thiosulfate was identified as the main interfering substance, and pretreatment was needed to eliminate it. This new method is more efficient, cost-effective, easier to operate, and more secure and accurate than existing methods.

Patient centered care disebut juga pelayanan yang berpusat pada seseorang, berpusat pada klien, pasien dan keluarga. Berdasarkan survei kepuasan pasien dirawat inap RS UMM bulan Juli dan Agustus 2015 didapatkan data bahwa masih terdapat pasien komplain tentangÂ  sikap dan komunikasi petugas kepada pasien/keluarga yang kurang baik. Ini menandakan bahwa sikap dan komunikasi yang dilakukan oleh petugas kepada pasien maupun keluarganya kurang bagus. Artinya penerapan patient centered care belum dijalankan dengan baik. Tujuan penelitian ini adalah untuk mengeksplorasi secara mendalam pengalaman pasien selama menjalani rawat inap terhadap penerapan patient centered care yang dilakukan olehÂ  RS UMM.Â  Metode yang digunakan dalam penelitian ini ialah kualitatif fenomenologi. Wawancara dilakukan secara mendalam kepada 8 informan yang dianggap mewakili pasien kelas 3, 2, 1 dan kelas utama. Hasil penelitian didapatkan pengalaman yang menyenangkan tentang penerapan PCC yaitu pasien senang mendapatkan pelayanan yang ramah danÂ  sopanÂ  dari petugas, pasien merasa dipedulikan oleh perawat selama dirawat, petugas berupaya berkomunikasi dengan baik, petugas memberikan pelayanan yang sama, petugas mengecek nama pasien ketika akan memberikan obat, makanan yang disediakan disesuaikanÂ  dengan kebutuhan dan gizi pasien. Kesimpulannya, sebagian besar pengalaman pasien rawat inap didapatkan bahwa RS UMM telah menerapkan PCC dengan cukup baik sehingga pasien merasa dikedepankan dalam proses perawatan maupun untuk memenuhi kebutuhannya.

Neoplasma yang berasal dari sel dendritik dan histiosit merupakan keganasan yang jarang terjadi, <1% dari semua neoplasma. Interdigitating dendritic cell sarcoma (IDCS) merupakan keganasan yang jarang terjadi yang berasal dari antigen-presenting cells sistem imun.Â  Keganasan ini seringkali melibatkan limfonodi, dan meskipun jarang dapat terjadi ekstranodal. Telah dilaporkan dua kasus dengan IDCS pada tulang. Kasus pertama, wanita 17 tahun dengan fraktur tulang paha kanan. Pemeriksaan radiologis menunjukkan fraktur 1/3 proksimal diafise dan lesi litik yang dicurigai fraktur patologis. Kasus kedua, laki-laki 15 tahun dengan massa pada region temporoparietal kanan. Pemeriksaan radiologis menunjukkan proses dengan lesi osteolitik pada calvaria yang dicurigai proses metastase. Analisa imunohistokimia pada kedua kasus tersebut menunjukkan antibodi anti S100 yang positif dan antibodi CD1a yang negatif. Pasien pertama telah mendapat kemoterapi dengan regimen CHOP (Siklofosfamid-Doksorubisin-Vinkristin-Prednison) sebanyak 6 siklus dan mengalami perbaikan secara klinis sedangkan kasus kedua kami kehilangan kontak.Â
Kombinasi Artesunat Injeksi dan Ekstrak Brotowali (Tinospora crispa (L) Miers) Menurunkan Derajat Parasitemia serta Meningkatkan Ekspresi HSP70 dan Endoglin pada Mencit C57BL/6J yang Diinfeksi Plasmodium berghei

Penemuan kombinasi terapi baru untuk malaria dianggap penting karena kemampuan resistensi dari Plasmodium terhadap pengobatan terdahulu. Sebanyak 18 mencit dibagi ke dalam kelompok kontrol negatif, kontrol positif, kelompok artesunat, serta kelompok kombinasi artesunat dengan brotowali (dosis 50 mg, 60 mg dan 70 mg). Selain kontrol negatif, semua mencit diinfeksi Plasmodium berghei. Selanjutnya diamati derajat parasitemianya sampai hari ke-7, kemudian dilakukan pemeriksaaan imunohistokimia guna mengetahui ekspresi HSP70 dan endoglin pada otak mencit. Kombinasi artesunat injeksi dan ekstrak brotowali terbukti dapat menurunkan derajat parasitemia lebih baik dari pemberian terapi tunggal artesunat dan meningkatkan ekspresi HSP70 dan endoglin. Kesimpulannya, kombinasi terapi malaria menggunakan artesunat dan brotowali terbukti berpotensi sebagai terapi kombinasi yang efektif terhadap malaria karena mampu menurunkan derajat parasitemia sampai 0% dan meningkatkan ekspresi HSP70 dan endoglin pada otak mencit C57BL/6J secara signifikan.Â

Skrining gizi menjadi tahapan awal penentuan risiko malnutrisi dan albumin sebagai salah satu parameter malnutrisi. Keduanya dapat mengidentifikasi status gizi dan menentukan intervensi gizi dalam mencegah komplikasi dan memperpendek masa lama rawat inap. Tujuan penelitian untuk menganalisis hubungan risiko malnutrisi yang diukur menggunakan Malnutrition Screening Tool (MST) dan kadar albumin serum terhadap lama rawat inap pasien kanker ginekologi. Penelitian observasional dengan rancangan kohort prospektif dilakukan pada bulan Februari s.d April 2016. Sebanyak 64 pasien dilakukan skrining risiko malnutrisi menggunakan MST dengan wawancara. Kadar albumin serum dan lama rawat inap dilihat dari catatan medis pasien. MST mampu mendeteksi risiko malnutrisi pada 33 orang (51,6%) dan tidak berisiko manlutrisi pada 31 orang (48,4%). Meskipun secara statistik tidak signifikan subjek berisiko malnutrisi meningkatkan lama rawat inap 0,66 kali (95% CI=0,29-1,51) dan hipoalbumin 1,31 kali (95% CI=0,47-3,66). Tindakan pembedahan dan status bekerja menjadi faktor yang berperan pada lama rawat inap pasien kanker ginekologi.

Komponen biomotorik kelincahan, daya ledak, dan kecepatan merupakan komponen yang harus dimiliki atlet sepak bola. Penelusuran genetik dapat menjadi salah satu metode talent profiling pada atlet sepak bola. Talent profiling belum pernah dilakukan pada kalangan atlet Indonesia terutama atlet yunior seperti atlet Unit Kegiatan Mahasiswa (UKM) Sepak Bola di (Universitas Jenderal Soedirman) UNSOED. Salah satu gen yang berhubungan dengan performa adalah gen ACTN3. Gen ACTN3 yang merupakan gen pengkode protein Î±-aktinin-3 pada serabut otot tipe cepat, diduga berpengaruh terhadap kelincahan, daya ledak dan kecepatan. Tujuan penelitian ini adalah untuk mengetahui hubungan polimorfisme gen ACTN3 dengan kelincahan, daya ledak dan kecepatan otot pada atlet sepakbola. Penelitian ini menggunakan rancangan studi observasional analitik dengan pendekatan cross sectional. Metode pengumpulan subjek pada penelitian ini menggunakan consecutive sampling. Subjek pada penelitian ini adalah 82 atlet yang mengikuti UKM sepak bola Universitas Jenderal Soedirman. Metode PCR-RFLP dan elektroforesis digunakan untuk melihat polimorfisme gen ACTN3. Sedangkan pengukuran komponen biomotorik menggunakan tes agilitas Illinois (kelincahan), jump meter digital (daya ledak) dan tes sprint 30 meter (kecepatan). Analisis data menggunakan uji ANOVA satu arah dengan tingkat kemaknaan p=0,05. Terdapat hubungan bermakna antara polimorfisme gen ACTN3 dengan daya ledak otot (p=0,027) dan tidak terdapat hubungan bermakna antara polimorfisme gen ACTN 3 dengan kelincahan (p=0,084) dan kecepatan (p=0,507). Rerata terbaik ketiga komponen biomotorik terdapat pada alel RR gen ACTN 3. Disimpulkan terdapat hubungan antara polimorfisme gen ACTN3 dengan daya ledak otot, tapi tidak terdapat hubungan antara polimorfisme gen ACTN 3 dengan kelincahan dan kecepatan pada atlet sepakbola.
The Use of Telerehabilitation Technologies for Cardiac Patients to Improve Rehabilitation Activities and Unify Organizations: Qualitative Study (Preprint)
Authors: Dinesen Birthe , Spindler Helle
Published: April 2018

BACKGROUND

Cardiovascular disease is a leading cause of death globally causing 31% of all deaths worldwide. The Danish health care system is characterized by fragmented delivery of services and rehabilitation activities. The Teledialog Telerehabilitation Program for cardiac patients was developed and tested to rectify fragmentation and improve the quality of care. The Teledialog program was based on the assumption that a common communication platform shared by health care professionals, patients, and relatives could reduce or eliminate the fragmentation in the rehabilitation process and improve cooperation between the health professionals.

OBJECTIVE

This study aimed to assess the interorganizational cooperation between health care professionals across sectors (hospitals, municipal health care centers) in a cardiac telerehabilitation program.

METHODS

Theories of networks between organizations, the sociology of professions, and the “community of practice” approach were used in a case study of a cardiac telerehabilitation program. A triangulation of data collection techniques were used including documents, participant observation (n=76 hours), and qualitative interviews with healthcare professionals (n=37). Data were analyzed using NVivo 11.0.

RESULTS

The case study of cooperation in an interorganizational context of cardiac telerehabilitation program is characterized by the following key themes and patterns: (1) integrated workflows via a shared digital rehabilitation plan that help integrate workflow between health care professions and organizations, (2) joint clinical practice showed as a community of practice in telerehabilitation developed across professions and organizations, and (3) unifying the organizations as cooperation has advanced via a joint telerehabilitation program across municipalities and hospitals.

CONCLUSIONS

The Teledialog Telerehabilitation Program was a new innovative cardiac program tested on a large scale across hospitals, health care centers, and municipalities. Assessments showed that the Teledialog program and its associated technologies helped improve interorganizational cooperation and reduce fragmentation. The program helped integrate the organizations and led to the creation of a community of practice. Further research is needed to explore long-term effects of implementation of telerehabilitation technologies and programs.
