Authors: Bestari Anikha Widya
Published: February 2017

Handling CKD (Chronic Kidney Disease) final stage is mostly done in Indonesia is hemodialysis. Hemodialysis can prevent death, but not fully restore the quality of life of patients as before. Psychosocial problems such as lack of family support sometimes be a severe problem that must be faced by the patient. While diabetes mellitus which is etiology of PGK can increase the risk of morbidity and mortality for patients. This study aimed to analyze influence of family support and DM status with hemodialysis patient’s quality of life. This study is an observational analytic study with cross sectional design. Samples of this study are 72 patients on hemodialysis Installation RSU Haji Surabaya, which is calculated using a simple random sampling from hemodialysis schedule. Data is collected using interviews and secondary data on the patient diagnosis document. The questionnaire is WHOQOL-BREF which assess quality of life and family support questionnaire in accordance with the theory of family support from House. The results showed that there is a influence between family support (p = 0.005) and diabetes status (p = 0.003) on the status of the patient's quality of life. From these two variables  known that DM status is strongest variable that influence quality of life. Therefore, interventions focused on controlling patients with DM and supportive therapy in the family. Keywords : Hemodialysis, Quality of Life, Family Support, Diabetes Mellitus (DM)

Published: February 2017

Introduction: Lead is a well-known toxic agent that makes an organ’s failure. Lead serum itself is infl uenced by δ-ALAD gene polymorphisms (Amino Levulinic Acid Dehydratase). δ-ALAD gene encodes an ALAD enzyme used for heme synthesis. The Characteristic of gene polymorphism may result in Glomerulo Filtration Rate (GFR) value as mark of renal failure. The goal of this study was to fi nd correlations between blood lead levels with GFR in terms of δ ALAD gene polymorphisms. Method: A cross-sectional design was used to perform this research. Thirty-eight gas stations workers in Banyumas were recruited in this study. δ-ALAD gene polymorphisms were characterized using PCR-RFLP method, while lead serum levels were quantifi ed by Atomic Absorption Spectrophotometer (AAS). In addition, Creatinin serum was done with a spectrophotometer and GFR value was formulated by means of the Schwartz method. Result: The studyshowed that the proportion of ALAD genotype for ALAD 1-1, 1-2 and 2-2 were 94.7%, 5.3%, and 0% respectively. The mean of serum levels in homozygous 1-1 was 15.94 ppb and heterozygote 1-2 was 1.15 ppb. GFR of participants ranged from 71.11 mL/min to 185.20 mL/min with a mean of 117.34mL/min. There was no correlation between serum Pb and GFR (p = 0.19). Study also could not determine the correlation between GFR and ALAD gene Polymorphism. Discussion: Study then concluded that there was no correlation between blood lead levels in the GFR on each δ-ALAD genotypes.Keywords: Lead intoxication, GFR, δ-ALAD, gas station workers

Introduction: Percentage of HIV-AIDS cases based on the types of work in East Java in 2011 shows that construction workers occupied ranks the top five ranked groups with 249 people (31%) after a group of commercial sex workers (CSWs) group.The purpose of this study was to determine the effectiveness of BCC approach to the reduction of contracting HIV risk behavior in the construction laborers. Method: This study used operational research design. In this study measures the effectiveness of behavior change of construction workers on the prevention of HIV transmission by comparing the behavior of the construction workers before and after the intervention. The subjects of this study were 150 people risk group of construction workers who work and are spread throughout the city of Surabaya. This research was carried out into three phases, namely, phase preintervention research, intervention research, and post-intervention phase of the study. Implemented in the first year and second year praintervensi stage implemented intervention and post-intervention phases. Result: The results of this study showed that 72% of construction workers is productive (18–35 years) and visit his family more than once a month (38%). There is 20% of construction workers had sex with commercial sex workers and no one was using drugs. By 50% of construction workers never get information about HIV/AIDS and as many as 48% never use the services of HIV/AIDS. Discussion: External motivation construction workers associated with the utilization of behavioral HIV/AIDS services with sufficient correlation. Strong external motivation is influenced by risk behaviors of HIV/AIDS were conducted and the desire to get help. Weak external motivation is influenced by a lack of exposure to information related to HIV/AIDS services. The results of the FGD stakeholders have the perception is the same if a construction worker is a high risk group of contracting HIV. Most of the construction workers not have enough knowledge for the prevention of HIV transmission because they do not have access to HIV care and behavior are at risk of contracting HIV by construction workers.Keywords: construction workers, behavior change communication, behavior

[abstFig src='/00290001/05.jpg' width='300' text='Schematic of the proposed system for actively localizing the sound source' ] Animals use two ears to localize the source of a sound, and this paper considers a robot system that localizes a sound source by using two microphones with active external reflectors that mimic movable pinnae. The body of the robot and the environment both affect the propagation of sound waves, which complicates mapping the acoustic cues to the source. The mapping may be multimodal, and the observed acoustic cues may lead to the incorrect estimation of the locations. In order to achieve sound source localization with such multimodal likelihoods, this paper presents a method for determining a configuration of active pinnae, which uses prior knowledge to optimize their location and orientation, and thus attenuates the effects of pseudo-peaks in the observations. The observations are also adversely affected by noise in the sensor signals, and thus Bayesian inference approach to process them is further introduced. Results of experiments that validate the proposed method are also presented.

[abstFig src='/00290001/09.jpg' width='300' text='3D sound source environmental map' ] The study proposes a probabilistic 3D sound source mapping system for a moving sensor unit. A microphone array is used for sound source localization and tracking based on the multiple signal classification (MUSIC) algorithm and a multiple-target tracking algorithm. Laser imaging detection and ranging (LIDAR) is used to generate a 3D geometric map and estimate the location of its six-degrees-of-freedom (6 DoF) using the state-of-the-art gyro-integrated iterative closest point simultaneous localization and mapping (G-ICP SLAM) method. Combining these modules provides sound detection in 3D global space for a moving robot. The sound position is then estimated using Monte Carlo localization from the time series of a tracked sound stream. The results of experiments using the hand-held sensor unit indicate that the method is effective for arbitrary motions of the sensor unit in environments with multiple sound sources.

[abstFig src='/00290001/17.jpg' width='300' text='System architecture for sound source detection using a quadcopter with a microphone array' ] This paper addresses sound source detection in an outdoor environment using a quadcopter with a microphone array. As the previously reported method has a high computational cost, we proposed a sound source detection algorithm called multiple signal classification based on incremental generalized singular value decomposition (iGSVD-MUSIC) that detects the sound source location and temporal activity at low computational cost. In addition, to relax the estimation error problem of a noise correlation matrix that is used in iGSVD-MUSIC, we proposed correlation matrix scaling (CMS) to achieve soft whitening of noise. As CMS requires a parameter to decide the degree of whitening, we analyzed the optimal value of the parameter by using numerical simulation. The prototype system based on the proposed methods was evaluated with two types of microphone arrays in an outdoor environment. The experimental results showed that the proposed iGSVD-MUSIC-CMS significantly improves sound source detection performance, and the prototype system achieves real-time processing. Moreover, we successfully clarified the behavior of the CMS parameter by using a numerical simulation in which the empirically-obtained optimal value corresponded with the analytical result.*

Keuntungan Komparatif Usahatani Ubikayu di Daerah Produksi Utama di Lampung dan Jawa Timur
Authors: Suryana Achmad
Published: February 2017

Abstrak

Tanaman ubikayu mempunyai dua peranan, yaitu sebagai tanaman pangan dan tanaman perdagangan. Produk ubikayu berupa gaplek, pelet, dan tapioka merupakan komoditi ekspor yang menempatkan Indonesia pada urutan kedua setelah Thailand sebagai negara pengekspor ubikayu. Permintaan gaplek di pasar intemasional selama 10 tahun terakhir meningkat pesat terutama dari negara-negara MEE, tetapi Indonesia tidak sempat memanfaatkannya. Penyebabnya adalah elastisitas penawaran rendah karena pengelolaan usahatani ubikayu rakyat masih subsisten. Hal ini tercermin dari produksi ubikayu yang tidak mengalami kenaikan pada 10 tahun terakhir. Penyebab lainnya adalah permintaan ubikayu untuk bahan baku industri dalam negeri meningkat dan sebagian besar produksi ubikayu digunakan sebagai bahan pangan. Masalah pengembangan komoditi memang banyak, tetapi dapat kita golongkan pada dua macam masalah pokok, yakni:
l.  Potensi pengadaan dilihat dari segi biaya produksi dan sumberdaya yang tersedia.
2. Kemampuan sistem tataniaga, yang harus tercermin pada kemampuan sistem itu memberikan respon terhadap perubahan permintaan pasar, di dalam maupun luar negeri.
Penelitian ini mencoba menemukan jawaban atas sebagian dari permasalahan pertama. Daerah Lampung dan Jawa Timur dipakai sebagai daerah penelitian karena kedua daerah ini merupakan propinsi utama penghasil ubikayu di Jawa dan luar Jawa.
Analisis Peran Jaringan Komunikasi Petani dalam Adopsi Inovasi Traktor Tangan di Kabupaten Cianjur, Jawa Barat
Authors: Rangkuti Parlaungan Adil
Published: February 2017

Penggunaan traktor tangan di Indonesia terus meningkat karena makin terbatasnya waktu, serta tenaga kerja manusia dan ternak untuk mengolah lahan sawah. Salah satu permasalahannya adalah bahwa proses adopsi inovasi traktor tangan masih rendah karena peran jaringan komunikasi petani yang belum dinamis. Hasil penelitian yang dilakukan di Desa Neglasari (Kecamatan Bojongpicung, Kabupaten Cianjur, Jawa Barat) ini menunjukkan bahwa dalam sosiometri jaringan komunikasi, interaksi komunikasi dalam adopsi inovasi traktor tangan membentuk jaringan yang cenderung terbuka, berbentuk bintang, atau roda. Pada umumnya hubungan komunikasi dilakukan dua arah dan sangat didominasi oleh tokoh-tokoh masyarakat yang berperan sebagai star. Jaringan komunikasi petani dalam kaitannya dengan nilai keterkaitan, keragaman, kekompakan dan keterbukaan kelompok tani, secara umum masih tergolong sedang dan rendah. Waktu yang dibutuhkan petani untuk mengadopsi inovasi teknologi traktor tangan dengan kategori perintis mencapai 31,4 persen, pelopor 23,7 persen, mayoritas dini 22,5 persen, mayoritas lambat 11,2 persen, dan kolot 11,2 persen. Produktivitas lahan berpengaruh positif terhadap tingkat keragaman (0,017) dan tingkat kekompakan (0,213), tetapi berpengaruh negatif terhadap tingkat keterkaitan (-0,472) dan tingkat keterbukaan (-0,642). Biaya pengolahan lahan hingga siap tanam berpengaruh positif terhadap tingkat keragaman (0,162) dan tingkat kekosmopolitanan (0,173), dan mempunyai kontribusi terbesar terhadap jaringan komunikasi pada tingkat kekompakan dengan nilai nyata 0,204. Harga gabah di tingkat petani berpengaruh negatif terhadap keterikatan (-0,067), tetapi berpengaruh positif terhadap jaringan komunikasi dengan tingkat keragaman (0,087), kekompakan (0,040) dan tingkat keterbukaan (0,080)

Published: February 2017

Pemerintah Daerah Tingkat II Kabupaten Situbondo sampai saat ini masih belum menetapkan wilayahnya untuk pengembangan kawasan agropolitan. Untuk itu sebelum program agropolitan dilaksanakan perlu dikaji terlebih dahulu tingkat keberlanjutan wilayah berbasis peternakan di Kabupaten Situbondo. Penelitian ini bertujuan untuk menganalisis indeks dan status keberlanjutan wilayah berbasis peternakan di Kabupaten Situbondo ditinjau dari lima dimensi keberlanjutan, yaitu: dimensi ekonomi, sosial budaya, infrastruktur dan teknologi, serta hukum dan kelembagaan. Penelitian meggunakan metode analisis Multidimensional Scaling (MDS) yang disebut RAP-BANGKAPET dan hasilnya dinyatakan dalam bentuk indeks dan status keberlanjutan. Untuk mengetahui atribut yang sensitif berpengaruh terhadap indeks dan status keberlanjutan dan pengaruh galat dilakukan analisis Leverage dan Monte Carlo.   Hasil analisis keberlanjutan menunjukkan bahwa dimensi ekologi berada pada status kurang berkelanjutan (46,50%), dimensi ekonomi cukup berkelanjutan (69,53%), dimensi sosial budaya cukup berkelanjutan (55,14%), dimensi infrastruktur dan teknologi kurang berkelanjutan (45,48%), serta dimensi hukum dan kelembagaan kurang berkelanjutan (47,46%). Dari 73 atribut yang dianalisis, 24 atribut yang perlu segera ditangani karena sensitif berpengaruh terhadap peningkatan indeks dan status keberlanjutan dengan tingkat galat (error) yang sangat kecil pada taraf kepercayaan 95 persen. Dalam rangka meningkatkan status keberlanjutan ke depan (jangka panjang), skenario yang perlu dilakukan adalah skenario progresif-optimistik dengan melakukan perbaikan secara menyeluruh terhadap semua atribut yang sensitif dalam peningkatan status kawasan.

Published: February 2017

ABSTRAK

Produksi kedelai domestik cenderung turun dari tahun ke tahun. Hal ini terkait dengan rendahnya partisipasi petani dalam usahatani tanaman kedelai. Penelitian ini ditujukan untuk memperoleh gambaran objektif mengenai profitabilitas usahatani kedelai di tiga agroekosistem yang berbeda yaitu di lahan sawah irigasi, lahan sawah tadah hujan, dan lahan tegalan. Analisis menggunakan pendekatan matrik analisis kebijakan (PAM). Data diperoleh dari hasil survei pada Tahun 2009 di tiga provinsi yaitu Jawa Barat, Jawa Timur dan Sulawesi Selatan. Hasil analisis menunjukkan bahwa usahatani kedelai di tiga agrosistem tersebut cukup efisien dan keunggulan kompetitifnya cukup memadai sebagai substitusi impor. Peningkatan partisipasi petani dalam usahatani kedelai terkendala oleh kurang tersedianya benih unggul bermutu, risiko usahatani yang cukup tinggi, dan tidak adanya jaminan harga jual kedelai yang layak.

Abstrak

Pemasaran susu segar sudah sejak lama merupakan masalah nasional yang masih belum dapat dipecahkan secara tuntas. Dengan terus ditingkatkannya produksi susu segar diantaranya dengan pemasukan bibit impor, maka masalah penyaluran produksi susu segar menjadi semakin serius. Dipihak lain ternyata untuk mencukupi kebutuhan konsumsi masih dengan susu impor sekitar 85 persen. Dalam upaya untuk memecahkan permasalahan diatas, salah satu segi yang perlu mendapat penanganan adalah segi permintaan untuk konsumsi. Dilihat dari besarnya volume susu impor, sebenarnya menunjukkan bahwa permintaan terhadap susu sudah cukup tinggi. Tapi yang masih rendah adalah permintaan terhadap susu segar produksi dalam negeri. Maka yang menjadi masalah adalah mengapa permintaan terhadap susu segar itu rendah. Faktor-faktor apa yang sebenarnya mempengaruhi besarnya permintaan itu dan bagaimana kepekaan daripada permintaan karena perubahan dari faktor-faktor yang mempengaruhinya.

Authors: Huang Chun-qiong , Liu Guo-dao , Bai Chang-jun
Published: February 2017

Aluminum ion (Al3+) toxicity is a major factor limiting plant production on acid soils. Species of zoysiagrass (Zoysia Willd.) are grown for lawn, turf, and soil conservation, especially in temperate zones. Herein, 46 zoysiagrass accessions obtained from eight provinces in China were evaluated for Al resistance using small-scale liquid culture. Each accession was grown in triplicate in nutrient solutions with 1500 μm AlCl3·6H2O (experimental) or without exposure to Al (control). The mean dry weights of the roots, shoots, and total bodies of the accessions relative to those of the nontreated controls were calculated after 60 days, and showed considerable diversity. Overall, the cv for the shoot, root, and total weights of the Al-treated accessions relative to the nontreated controls were 45.78%, 56.67%, and 42.84%, respectively. A cluster analysis based on Al resistance and subordinate function values revealed that 12 of the 46 zoysiagrass accessions (26.09%) were resistant to Al, 9 (19.57%) were moderately resistant, and 25 (54.35%) were sensitive to Al stress. These 46 zoysiagrass accessions from China have great potential for horticultural breeding and development, and for research into mechanisms that underlie Al resistance.
Salt Exclusion and Mycorrhizal Symbiosis Increase Tolerance to NaCl and CaCl2 Salinity in ‘Siam Queen’ Basil
Authors: Scagel Carolyn F. , Bryla David R. , Lee Jungmin
Published: February 2017

A study was conducted to evaluate the effects of salinity on growth and nutrient uptake in basil (Ocimum basilicum L. ‘Siam Queen’). Plants were fertilized with a complete nutrient solution and exposed to no, low, or moderate levels of salinity using NaCl or CaCl2. The plants in control and moderate salinity treatments were also inoculated or not with the arbuscular mycorrhizal fungus (AMF), Rhizophagus irregularis (Blaszk., Wubet, Renker, & Buscot) C. Walker & A. Schler., to determine whether AMF mitigate the effects of salinity stress. Electrical conductivity (EC) of leachate collected from salinity treatments reached levels ≥8 dS·m−1 but had no effect on plant growth in the first 41 days of treatment. However, by 75 days, plants exposed to low and moderate levels of NaCl and CaCl2 had 20% to 38% less dry weight (DW) than controls. Reductions in DW were similar between NaCl and CaCl2 and was greater in roots than in shoots. Both NaCl and CaCl2 salinity reduced stomatal conductance (gS) within 25 days, but hastened flowering by 2–3 days, and nearly doubled the DW of flowers at 75 days. Salinity from NaCl increased uptake of Na and reduced uptake of Ca, whereas CaCl2 salinity increased uptake of Ca and reduced uptake of Mg and Mn. Both salts also increased relative uptake of N, Cu, and Zn, and reduced relative uptake of S and Fe. In general, Na was concentrated in roots and excluded from shoots, whereas Cl was concentrated primarily in leaves. Both salts reduced root colonization by AMF. However, AMF increased gS by 10% with NaCl and 22% with CaCl2, and increased shoot DW by 22% and 43%, respectively. Other than Ca and Cl, AMF did not enhance nutrient uptake under NaCl or CaCl2 salinity. ‘Siam Queen’ basil was moderately tolerant to salinity, due at least in part to exclusion of Na from the shoots, and inoculation with AMF increased tolerance to both NaCl and CaCl2 salinity. Differences in basil tolerance to NaCl and CaCl2 indicate plants may have different mechanisms for dealing with salinity and sensitivity is not solely a function of EC. This highlights the importance of understanding the source of salinity in irrigation waters and soil for predicting damage.
Production of Triploid Hydrangea macrophylla via Unreduced Gamete Breeding
Authors: Alexander Lisa
Published: February 2017

Hydrangea macrophylla (Thunb.) Ser., florist’s or bigleaf hydrangea, is the most economically important member of the Hydrangea genus, which accounted for over $120,000,000 in U.S. nursery sales in 2014. Both diploid and triploid H. macrophylla cultivars exist and there is some evidence that triploidy leads to larger plant and floral structures. The diploid cultivar, H. macrophylla ‘Trophee’, was previously shown to have a bimodal pollen size distribution which may be indicative of unreduced gametes. We used H. macrophylla ‘Trophee’ as a parent in a series of crosses with other diploid H. macrophylla cultivars. The objective of this study was to evaluate reciprocal full-sibling H. macrophylla families for ploidy and phenotype, determine the impact of ploidy on phenotype, and determine the efficacy of unreduced gamete breeding. Diploids and triploids were found in the offspring pool with mean 2C genome sizes of 4.5 and 6.7 pg, respectively. All offspring from crosses with ‘Trophee’ as the female parent were diploid as expected. The full-sibling family with ‘Trophee’ as the male parent contained 94% triploids, supporting the hypothesis that the bimodal pollen size distribution of ‘Trophee’ reflects the presence of unreduced male gametes. Triploids had fewer, wider inflorescences than diploids. The stems of triploids were 16% thicker and their leaves were 20% larger than those of diploid full and half-siblings. Triploids had significantly larger stomata (9.0 μm2) than diploids (5.9 μm2). These results establish a link between ploidy and phenotype in plants of similar genetic background and support the efficacy of unreduced gametes in polyploidy breeding.

Published: February 2017

In containerized crop production, subirrigation is an attractive solution to reduce excessive water runoff and nutrient loss. However, this irrigation method is mainly used for the cultivation of containerized ornamental plants, with limited research on the cultivation of vegetable species. In the present study, we assessed the feasibility of using a subirrigation system on growth, yield, and nutrient status of bell pepper plants (Capsicum annuum L.) grown in 30-cm-tall (13-L) containers by measuring the effects of flooding depth (10 and 15 cm) and duration (20 and 30 minutes) and compared with drip-fertigated plants. Subirrigated bell pepper plants exhibited a fruit number and yield comparable to those of drip-fertigated plants when the solution depth was held at 15 cm for 30 minutes. There was a substantial increase in the electrical conductivity (EC) in the medium top layers for all subirrigated plants, but this was up to 50% lower when plants were irrigated/fertigated to a 15-cm depth for 30 minutes. The higher yield of subirrigated plants flooded to a depth of 15 cm for 30 minutes was associated with a decrease in Ca concentration in the plant tissue (−16%), probably due to a dilution effect associated with the higher biomass produced by these plants. The higher nutrient use efficiency (NUE) attributed to subirrigation systems is not only due to nutrient accumulation in the growing medium, but also to a higher uptake by the plants, as compared with drip-fertigated plants, as subirrigated plants with flooding depth and duration of 15 minutes and 30 cm contained 47% higher N, 44% P, 44% K, 17% Ca, 60% Mg, and 76% S. Subirrigation of bell pepper plants is a reliable and feasible irrigation system provided flooding depth and duration are considered.

A field study was conducted to evaluate efficacy of soil-applied zinc (Zn) fertilizer on young pecan [Carya illinoinensis (Wangenh.) K. Koch] trees growing in alkaline, calcareous soils. Chelated Zn ethylenediaminetetraacetic acid (ZnEDTA) was applied at rates of 0, 2.2, or 4.4 kg·ha−1 of Zn via injection into irrigation water (fertigation) in microsprinkler irrigated ‘Western’ and ‘Wichita’ trees. Over the 5-year duration of the study, leaf Zn levels were increased from 22 to 35 µg·g−1 in the highest rate of ZnEDTA treatment compared with 7 to 14 µg·g−1 in unfertilized trees. Zn concentrations in shoot and root tissues were also elevated in Zn-treated trees. Zn treatments largely eliminated visible Zn deficiency symptoms, and increased trunk diameter growth compared with untreated trees. Nut yield (in the third through fifth seasons) were also increased as a result of Zn fertilization. No additional benefit in terms of trunk diameter growth or nut yield was observed by adding a higher rate of Zn (4.4 kg·ha−1) vs. the lower rate (2.2 kg·ha−1). ‘Western’ and ‘Wichita’ trees responded similarly to Zn fertigation.
Sobre la necesidad de reconocimiento
Authors: Viveros Chavarría Edison Francisco
Published: February 2017

En este artículo de reflexión se analiza el problema del reconocimiento. La tesis que se argumenta es que hace parte de la naturaleza humana la búsqueda de reconocimiento y esto constituye una necesidad de alteridad. La necesidad de ser reconocidos no es un defecto o una actitud enfermiza de los seres humanos. Es el “psicologismo” el que lo ha hecho parecer de esa manera con su excesiva dirección al sujeto que se piensa a sí mismo. El “psicologismo” es una apología a la egología que justifica el recinto de la subjetividad por encima de la relación con el otro. Se concluye que solo en la responsabilidad absoluta por el otro se llega a ser sujeto. No es en el solipsismo ni en el “psicologismo”, sino en la alteridad como se llega a la dinámica relación del reconocimiento mutuo. El sujeto atrapado en el “psicologismo” está en completa satisfacción consigo mismo, no necesita el encuentro con los otros.
La mística en los “afectos” de la poetisa Del Castillo: una experiencia liminal
Authors: Reinoso Fonseca Nelson Ramiro
Published: February 2017

El artículo tiene como propósito dar cuenta de la experiencia mística expresada en los Afectos Espirituales por la poetisa neogranadina de Tunja, Sor Josefa Del Castillo (1671-1742). Este famoso texto, de la época hispanoamericana colonial, permite explorar la mística, pero no como una enfermedad ni como una producción de gozo, sino como un fenómeno que encubre la realidad estética. Uno de los objetivos es responder, principalmente, ¿en qué consiste la experiencia mística, poetizada por Castillo, en los Afectos Espirituales?, teniendo como clave hermenéutica la liminalidad desde el horizonte filosófico medieval y contemporáneo. De ahí que, en el primer apartado, se presenta una breve semblanza sobre la poetisa neogranadina; en el segundo, se hace una aproximación al método hermenéutico elegido, de cuño diltheyano, bajo el concepto de liminalidad. En el tercero, se atiende al concepto de vivencia, desde Dilthey, en la mística de los Afectos. En el cuarto apartado, se aborda la realidad estética en virtud de conceptos como los que ofrecen, Bajtín, Ficino, entre otros, y del lenguaje simbólico-poético. El artículo concluye con esa realidad estética que permite descubrir la coincidencia de sentido de su elaboración poético-simbólica y de su vivencia mística, con el concepto de “furor divino” del renacentista Marsilio Ficino, y que constituye la experiencia mística de la poetisa, cuya obra poética insinuaría claves desconocidas para leer de otra forma el pensamiento histórico-cultural y religioso colombiano, del período colonial hasta nuestros días.
“Veo a los humanos como a árboles”: aproximación exegética al relato de curación del Ciego de Betsaida (Mc 8:22-26)
Authors: Casas Ramírez Juan Alberto
Published: February 2017

Este artículo propone un análisis exegético del relato bíblico de la curación del ciego de Betsaida (Mc 8:22-26) a partir del desarrollo de tres aproximaciones sucesivas, interdependientes y acumulativas. En primer lugar se aborda la perícopa mediante  la presentación de la versión griega, su estructura narrativa y su traducción, de corte literal. En segundo lugar se abordan los contextos narrativos del texto desde su marco literario y narrativo. Finalmente, se analiza cada una de las escenas del relato tratando de dilucidar su sentido simbólico.

Comparison of in situ DGT measurement with ex situ methods for predicting cadmium bioavailability in soils with combined pollution to biotas

To assess the capabilities of the different techniques in predicting Cadmium (Cd) bioavailability in Cd-contaminated soils with the addition of Zn, one in situ technique (diffusive gradients in thin films; DGT) was compared with soil solution concentration and four widely used single-step extraction methods (acetic acid, EDTA, sodium acetate and CaCl2). Wheat and maize were selected as tested species. The results demonstrated that single Cd-polluted soils inhibited the growth of wheat and maize significantly compared with control plants; the shoot and root biomasses of the plants both dropped significantly (P < 0.05). The addition of Zn exhibited a strong antagonism to the physiological toxicity induced by Cd. The Pearson correlation coefficient presented positive correlations (P < 0.01, R > 0.9) between Cd concentrations in two plants and Cd bioavailability indicated by each method in soils. Consequently, the results indicated that the DGT technique could be regarded as a good predictor of Cd bioavailability to plants, comparable to soil solution concentration and the four single-step extraction methods. Because the DGT technique can offer in situ data, it is expected to be widely used in more areas.

AbstractJournalists play an important role as the fourth pillar of democracy. Doing so, journalists should be independent and separated from outside interference. This independence is not only applied to the relationship of journalistandthe government, but also applied to the relationship of journalists and news sources such as higher education institutions. In obtaining the proclamation of higher education institutions, journalists often intersect with public relations practitioners who also perform the task of media relations to gain publicity. This study aims to determine how to deal with the envelope cultureof journalists conducted by public relations practitioners of higher education institutions in Yogyakarta. The method used in this research is descriptive qualitative using interviews and focus group discussions on five journalists from famous print media in Yogyakarta, namely Kompas, Tribun, Harian Jogja, Kedaulatan Rakyat and Radar Jogja. The results of this study show that a good relationship between journalists and public relations practitioners play an important role in preventing the envelope culture and also, public relations practitioners need to have an understanding of newsworthy issues. In addition, journalismethics (KEJ) from the journalist associations can also be used as a strong reference in relation to the ban the envelope culture among journalists.AbstrakWartawan memainkan peranan penting sebagai pilar ke-4 dalam demokrasi. Untuk itu wartawan harus bersikap independen dan terlepas dari intervensi pihak luar. Independensi ini tidak hanya berlaku pada hubungan wartawan dengan pemerintah saja, namun juga berlaku pada hubungan wartawan dengan sumber beritanya seperti institusi pendidikan tinggi. Dalam memperoleh pemberitaan dari institusi pendidikan tinggi, wartawan sering kali bersinggungan dengan praktisi public relations yang juga melakukan tugas media relations untuk memperoleh publikasi. Penelitian ini bertujuan untuk mengetahui bagaimana para wartawan menyikapi budaya amplop yang dilakukan oleh praktisi public relations institusi pendidikan tinggi di Yogyakarta. Metode penelitian yang digunakan dalam penelitian ini adalah deskriptif kualitatif dengan melakukan wawancara dan FGD pada lima orang wartawan dari media cetak di Yogyakarta, yaitu Kompas, Tribun, Harian Jogja, Kedaulatan Rakyat dan Radar Jogja. Hasil dari penelitian ini menunjukkan bahwa relasi yang baik antara wartawan dan praktisi public relations memainkan peranan penting dalam mencegah adanya budaya amplop dan perlu adanya strategi pengolahan isu yang bernilai berita. Selain itu, Kode Etik Jurnalistik (KEJ) yang dicetuskan asosiasi wartawan juga dapat dijadikan acuan yang kuat dalam kaitannya dengan larangan budaya amplop di kalangan wartawan.Keywords: Journalist, Envelope Culture, Journalism Ethics
