Del concepto formal a la conceptualización sistémica en el diseño arquitectónico
Authors: Flores Gutiérrez Avatar
Published: January 2021

La idea de que el concepto en el diseño arquitectónico atiende a una analogía formal está extendida. La analogía formal del concepto suele estar vinculada únicamente a aspectos simbólicos de la composición para el observador y no a la esencia de lo descubierto en el proceso de investigación y análisis proyectual. Desde la perspectiva del fenómeno arquitectónico como sistema, esta idea provoca un rompimiento entre la investigación proyectual y la forma, y preserva la dicotomía forma-función. En este artículo se aborda la idea de una perspectiva sistémica del fenómeno arquitectónico fundamentada en la noción de autopoiesis de Maturana y Varela, de los sistemas de Christopher Alexander, y la investigación de Flores sobre el fenómeno arquitectónico. El texto concluye con la idea de que, al dejar fuera al concepto como guía de composición formal y adoptar un proceso de conceptualización sistémica, el diseñador puede ampliar los límites de su investigación para buscar no sólo la configuración y relaciones adecuadas para la actividad, sino la atmósfera necesaria para dichas actividades.

Authors: Sharma Rohit , Kumar Sandeep
Published: January 2021

Genetic diversity of seven genotypes of Brassica campestris was evaluated by using RAPD primers. A total of 15 DNA bands were revealed wherein 11 polymorphic bands were observed. Highest polymorphism was showed by the primer OPA 7 (87.50%) and lowest by the primer OPA 9 (57.14%). Relatively higher genetic diversity was found among the collected individuals. A maximum similarity based on Jaccard coefficient was showed highest and lowest value (0.750) and (0.364) respectively. The UPGMA cluster analysis revealed three main group of clusters in which one group was found to be sub grouped and other two main groups were found to be divergent. Cluster analysis revealed distant relationship among all the cultivars used in this study.Based on our study, RAPD analysis proved to be a useful tool in assessing the genetic diversity of leafy Brassica germplasm. These results also proved that RAPD markers are highly suitable and efficient tool for genetic characterization of many plant species including oilseed rape and other species.

Published: January 2021

Wood usage has increased with time, thus, there is need to investigate how wood can be treated with human and environmentally friendly preservative which is effective in protecting wood from termites and other agents of wood deterioration, or improve the wood physical, chemical, mechanical and biological characteristics. The aim of this study was therefore to evaluate the effects of neem oil on Milicia excelsa wood preservation. Treated and untreated pieces of Milicia excelsa wood samples were used to carry out this experiment, a soil bed, and an internal wood exposure to termite’s test was carried out, and measurements taken using a digital weighing machine. The results obtained showed that, when Milicia excelsa is treated with neem oil, its Rate of Decay (ROD) reduces as compared to the untreated pieces. Also, neem oil treated wood when exposed to termite’s attack experiences a slower weight loss compared to untreated samples with significant weight loss. Neem oil is thus not only effective in preserving woods, but also non- toxic to human and the environment.
Model Implementasi Bioenginering Sebagai Upaya Mitigasi Longsor

Published: January 2021

Landslide is one of the high frequency disasters that occur in Indonesia. The incident recurs every year with a different location. The fact that landslide hazards are used intensively for agricultural cultivation due to economic considerations. One of the efforts to mitigate this disaster is the Bioenginering implementation approach. Bioenginering activity is the application of landslide hazard area management by managing plants / vegetation. The purpose of this research is to implement a vegetative technology implementation model as an effort to mitigate landslides. Bioenginering implementation is designed with a combination of ecological and socio-economic approaches. The results of this combination are consulted with the affected community and consider various vegetation alternatives. The selected vegetation not only has an ecological function but also an economic function. With these considerations, a vegetation design is obtained with a combination of upper strata (trees), middle and lower strata. For the upper strata it is recommended to plant Petai (Parkia speciosa) and Durian (Durio zibenthinus), for the middle strata, namely Coffee (Coffea arabica) and lower strata plants are pineapple (Ananas commocus). The combination of plants such as the implementation at the field level will be accepted by the farming community, because every certain period of time the farmers will be able to harvest their crops without having to remove the plants or cut down the plants. Maintaining the level of land cover and land use has implications for maintaining the stability of soil moisture conditions which in turn can reduce the threat of landslides in landslide hazard areas.

Published: January 2021

Investigations on the help-seeking behavior of academic library patrons have to date primarily focused on the undergraduate experience, most often in the context of reference interactions. This study seeks to explore the help-seeking behaviors of a different audience - faculty in the natural and physical sciences at an R2 land-grant university. Eighteen faculty in the natural and physical sciences at the University of Idaho were individually interviewed using an in-depth qualitative interview format and all transcripts were coded and analyzed using an open transcript data visualization tool created at the University of Idaho Library.
Responses revealed that faculty are seeking help from colleagues; peers outside the university, via connections formed in graduate school or professional circles; and through DIY solutions like "just googling it," but less often through university resources and programs. Using the results of this project as a starting point, we will explore how libraries might better understand the help-seeking behavior of research faculty, with an eye towards developing services and sources that better meet faculty research needs.

Intraoperative evaluation of sentinel lymph node in the era of acosog z0011
Authors: Sanvido Vanessa Monteiro , Elias Simone , Facina Gil , Nazário Afonso Celso Pinto
Published: January 2021

Introduction: Intraoperative evaluation of sentinel lymph node was routinely conducted to assess the presence or absence of metastasis and decide, during the same surgical procedure, whether to perform an axillary dissection, which would avoid a second surgical procedure. However, with the current recommendations for conservative axillary treatment, the role of the intraoperative assessment is questionable. Results of the American College of Surgeons Oncology Group Z0011 (ACOSOG Z0011) randomized trial allow skipping the axillary lymph node dissection in patients with two positive axillary sentinel lymph nodes treated with conservative surgery, which would also allow not performing the intraoperative evaluation of sentinel lymph node because the result would not change the surgical approach. However, the rate of axillary re-excision was not described for cases of ACOSOG Z0011 exclusion criteria after definite anatomopathological results. Objectives: To assess the rate of axillary retreatment in patients submitted to conservative breast surgery in the era of ACOSOG Z0011. Method: This is a retrospective cohort study of patients who had invasive breast carcinoma up to 5 cm, clinically negative axilla, and underwent conservative breast surgery and sentinel lymph node dissection from February 2008 to December 2018. Results: We evaluated 415 patients – 318 (76.7%) with negative sentinel lymph node, and 97 (23.3%) with positive. Among positive cases, 56 (57.8%) were treated with sentinel lymph node biopsy, and 41 (42.2%) were submitted to axillary lymph node dissection. Intraoperative evaluation occurred in 90.2% of cases prior to the publication of ACOSOG Z0011, decreasing to 30.8% after publication (p<0.00001). The rate of surgical re-excision due to ACOSOG Z0011 exclusion criteria was only 3.7%. The main causes were the presence of metastasis in three or more axillary lymph nodes or capsular extravasation. Conclusions: Intraoperative evaluation of sentinel lymph node substantially decreased in patients with early-stage breast carcinoma treated with conservative surgery and sentinel lymph node biopsy after implementing the axillary treatment proposed in the ACOSOG Z0011 guidelines, and the rate of axillary surgical retreatment due to exclusion criteria was minimal.
Case report of adenoid cystic carcinoma of the breast – a rare lesion with favorable prognosis

Published: January 2021

Introduction: Adenoid cystic carcinoma (ACC) is a rare type of breast tumor – less than 0.1% of breast malignancies. Usually, ACC is triple-negative, with lymph node involvement not exceeding 2%, and metastases are uncommon. When localized, the disease is indolent with an excellent prognosis. Objective: To report a case of ACC of the breast and provide data for the medical literature. Method/Case report: J.S.M.S., 44 years old, had a 1 cm nodule in the right breast (RB) and free axillae. Mammography (MMG) showed focal asymmetry in the upper outer quadrant (UOQ) and BI-RADS 0. Ultrasound (US) revealed a solid, circumscribed, periareolar lesion with areas of cystic degeneration, 1.2 cm, BI-RADS 3. Fine-needle aspiration biopsy (FNAB) suggested fibroadenoma. Lesion resection led to the diagnosis of ACC, histological grade 1 (HG1), nuclear grade 1 (NG1), with associated ductal carcinoma in situ (DCIS), and sentinel lymph node with no neoplasia. Immunohistochemistry (IHC) revealed estrogen receptor-negative (ER-), progesterone receptor-negative (PR-), HER2 negative (HER2-), and Ki67 10%. Staging had no evidence of distant disease. The patient did not receive chemotherapy (CT) but underwent 18 sessions of radiotherapy (RT) in the breast with a boost to the tumor bed. She remains disease-free at 8 months of follow-up. Results/Discussion: ACC has low malignant potential with histology similar to that of primary ACC of the salivary gland (which is aggressive); in the breast, it represents 0.058% of all ACC cases. It is more common in Caucasian women aged 60 to 70 years and usually subareolar (approximately 50% of cases). Imaging tests are nonspecific. ACC has lymph node involvement in about 2% of cases. Histology shows epithelial and myoepithelial cells distributed in the classic tubular or cribriform architecture. IHC reveals epithelial cells positive for CD117 and myoepithelial cells positive for smooth muscle actin, calponin, and p63. ACC of the breast expresses proto-oncogene c-KIT and a chromosomal translocation similar to its salivary counterpart: t (6; 9) (q22-23; p23-24). Treatment consists of surgery with free margins. Axillary dissection, CT, and RT have a questionable role due to the indolent course of the disease. Until now, small studies have not suggested a benefit in overall survival when adding adjuvant CT. Although triple-negative, its prognosis is favorable. Local recurrence is approximately 3–18%, and 10-year survival is above 90%. Conclusion: The rarity of these tumors and their favorable course raise questions about the best treatment for ACC. The benefit of axillary dissection, CT, or RT remains unknown because the prognosis seems very favorable with only surgery, despite its triple-negative status. Further studies are necessary to adopt the optimal strategy for these tumors.
El relato disciplinar consagrado en torno a la sociologí­a universitaria en dictadura y la "producción de ausencias": estudiar sociologí­a en Antofagasta, 1972-1984
Authors: Donoso Alina
Published: January 2021

Este artí­culo presenta la experiencia de institucionalización académica de la sociologí­a en la ex Universidad del Norte (Antofagasta, Chile, 1972-1984), actual Universidad Católica del Norte, hasta hoy ausente del discurso e historización de la sociologí­a chilena. A partir de este caso, se plantea la necesidad de analizar crí­ticamente la construcción del relato disciplinar consagrado acerca de la sociologí­a en Chile durante los ochenta, para visibilizar ciertas ausencias sobre la institucionalización y la reestructuración de la disciplina. Se advierte que la dificultad para registrar las experiencias de sociologí­as regionales no es atribuible solo al impacto de la dictadura civil-militar en la disciplina, sino a operaciones propias del campo. La investigación articula el enfoque de la historia reciente y los estudios sociales de la ciencia.

Por consiguiente, lo realizado permitió descubrir que finalmente son tres las motivaciones para elegir Talca como lugar para vivir: poseer redes migratorias en la comuna, tener ofertas laborales en la zona y el atractivo que supone para algunos/as una ciudad intermedia agraria como esta.
Movilización cí­vica, redes sociales y neoliberalismo: resistencias en México y Ecuador, 2018-2019
Authors: De la Garza Montemayor Daniel Javier , Riera Robles Gabriela Estefaní­a
Published: January 2021

En América Latina, han surgido diversos gobiernos cuyas polí­ticas públicas se basan en la doctrina neoliberal, pero también esta región ha sido un escenario de una férrea oposición a este sistema. En los últimos años, las redes sociales han funcionado como un espacio de interacción, permitiendo organización cí­vica, así­ como actos de resistencia. En el presente artí­culo, se examinarán dos casos en América Latina donde las redes sociales fueron un instrumento importante en la resistencia a las polí­ticas de corte neoliberal. Con respecto a México, las plataformas virtuales resultaron clave para la victoria del candidato de la izquierda, Andrés Manuel López Obrador, un triunfo que puso fin a 36 años de gobiernos liberales. De igual forma, en Ecuador las redes sociales fueron clave para la movilización social que detuvo la aplicación de polí­ticas públicas neoliberales. El principal contraste es que en México la organización fue de carácter institucional, mientras que en el caso ecuatoriano fue a través de movilizaciones. Sin embargo, en ambos casos coincide observar que la esfera pública virtual fue un espacio de articulación y de oposición al liberalismo. La estrategia metodológica fue cualitativa, basada en un análisis fenomenológico de los casos mencionados y para conseguir el objetivo, se utilizó la herramienta documental.
Pronunciamiento institucional del neoliberalismo chileno: Análisis del Acuerdo Nacional por la Paz y la Nueva Constitución
Authors: Farí­as Carrión Emmanuel
Published: January 2021

Desde el 18 de octubre de 2019, Chile vive una crisis institucional que ha sido identificada debido al espí­ritu subsidiario que existe en la institucionalidad chilena. Esto significa que el sistema polí­tico experimenta por primera vez la posibilidad de lograr una Constitución con una participación amplia de la sociedad civil, ¿esto es así­? Este argumento analizará el evento polí­tico que nos lleva a este momento constituyente: el Acuerdo por la `Paz y la Nueva Constitución. Se realizará una analogí­a entre el acuerdo nacional para la transición a la plena democracia, pactado en la dictadura de Pinochet, y el actual acuerdo nacional por la paz y la nueva Constitución, que aparece en la democracia pospinochetista. Ambos acuerdos se caracterizan por compartir ciertas analogí­as: anular al pueblo como agente polí­tico y continuar con el programa de modernidad, el cual ha traí­do como consecuencia la institucionalización de la democracia liberal. Luego, se utilizarán algunas posiciones teóricas para poder realizar un análisis desde la sociologí­a polí­tica y finalmente examinar si en este acuerdo existe una real pretensión democratizadora.

On September 13, 2020, an earthquake with a magnitude of Mw = 4.8 occurred in the Uglegorsk district of the Sakhalin region. Residents of the localities nearest to the epicenter felt it with a force of up to 5 points on the MSK-64 scale. A total of 62 aftershocks were recorded. The seismic process lasted for about two days, the major mass of aftershocks was registered during the first 7 hours. The epicenters of the registered earthquakes are confined to the system of the regional West Sakhalin fault. However, the fact of active mining of brown coal at the Solntsevskii quarry and massive blasting in the epicentral zone of the Uglegorsk earthquake does not exclude the relation between the seismic process and technogenic seismicity. The article presents the results of observations of the seismic process in the epicentral zone of the Uglegorsk earthquake in September 2020 and considers the probable causes of its occurrence.

Processes of the formation of high-coercivity state of Sm0.85Zr0.15(Co0.702Cu0.088Fe0.210)z alloys with different z = 6.0, 6.5 and 6.8, which is the value characterized the relationship of (4f-,4d-)/(3d-) elements in these alloys, are studied. It is shown the interrelation of the chemical composition of samples and their microstructure with the coercive force formed in the course of isothermal tempering and tempering during slow cooling (or stepped tempering). The interrelation of the high-coercivity state of the alloys and quantitative ratio (volume fractions) of the main structural components based on the 2:17R and 1:5H phases is discussed. It is shown that the cellular morphology of the alloy, which corresponds to the high-coercivity state, forms during isothermal tempering, whereas the final phase compositions of the main structural components form in the temperature range from the isothermal aging temperature to 400 °С during stepped (slow) cooling or upon quenching. The magnetic properties of sample in the high-coercivity state are determined by the degree of completeness of phase transformations of the main structural components; this directly depends on their quantitative relationships and the relationship of the (4f-,4d-)/(3d-) elements, i.e., on the z value in the alloy formula (Sm,Zr)(Со,Cu,Fe)z.

The formation of gas-filled bubbles, which is one of the indicators and quantitative criteria for radiation degradation of the surface layer of K-208 glass irradiated by 20-keV electrons, and the effect of ITO (Indium tin oxide) film deposited on the glass, are investigated. Using atomic force microscopy, the nucleation of oxygen bubbles in the surface layer of glass irradiated with a fluence (Φ) of the order of 1015 cm–2 at a particle flux density (φ) of 2·1010 cm–2·s–1 was detected. Gas-filled bubbles appear on the surface of samples with an ITO film at Φ ≥ 4·1015 cm–2 in smaller amounts but larger sizes than on glass without a film. The formation of oxygen bubbles is explained by the formation of a negative charge region in the surface layer of the irradiated glass, in the field of which sodium ions migrate, which plays a key role in the release of non-bridge oxygen atoms. Migration and aggregation of liberated oxygen atoms in defective places in the glass grid leads to the formation of gas-filled bubbles.

Crystalline composite structures based on titanium dioxide modified by magnetite particles with improved sorption and photocatalytic properties were obtained by a microwave-assisted method. This method is based on a polyol method synthesis of titanium glycolate using microwave heating and followed by the water treatment under microwave heating at 2.45 GHz, without using the calcination stage at high temperatures. It was found that the treatment of titanium glycolates in water under the influence of microwave heating leads to the formation of the crystal structure of titanium dioxide (polymorphic anatase modification). Using scanning electron microscopy, it was shown that during the synthesis of composite structures based on titanium dioxide, the formation of particles of a spherical and rod-shaped form. The resulting materials were characterized by electron microscopy, X-ray phase analysis, dynamic light scattering, and low-temperature nitrogen adsorption/desorption. The analysis of the influence of structural and morphological features on the adsorption capacity and photocatalytic activity of the composites is carried out. A comparative analysis of the photocatalytic activity of the obtained composites in the decomposition of the Rhodamine B dye under UV radiation showed that the most effective dye removal (~ 99 %) were observed in the presence of both spherical and rod-shaped composite structures as catalysts containing 1 % of magnetite.
Las razones de la preferencia hispana por la doctrina jurídica de Krause con respecto a la filosofía de Hegel
Authors: Manzanero Delia
Published: January 2021

Este estudio está consagrado a puntualizar las líneas generales de la traslación, recepción y asimilación de la filosofía del derecho de K. Ch. F. Krause (1781 -1832) y de G. W. F. Hegel (1770-1831) en la España del siglo XIX. Nuestro objetivo es hacer un examen crítico de algunas de las razones –históricas, sociológicas, religiosas, filosóficas y materiales– que explican por qué fue acogida con preferencia la filosofía de Krause en lugar de la filosofía hegeliana. Asimismo, se pasa lista a las críticas y censuras que se dieron en el choque del hegelismo/krausismo con la realidad ideológica y sociocultural hispánica decimonónica. Por último, se analizan algunos testimonios de krausistas acerca de los motivos que se suelen argüir para justificar la superioridad de la doctrina de Krause por su afinidad filosófica y espiritual con la sensibilidad religiosa tradicional de la cultura española y sus méritos como filosofía práctica.

El ius gentium y la idea liberal de un orden mundial justo en John Rawls
Authors: Llano Alonso Fernando Higinio

Este artículo se centra en The Law of Peoples (1999), libro con el que John Rawls cierra el tríptico de su concepción socio-democrática de la justicia dentro de la tradición liberal, iniciada a principios de la década de los ‘70 con A Theory of Justice (1971), donde describe la justicia como equidad como un ideal moral universal al que deben aspirar todas las sociedades, y continuada dos décadas más tarde con Political Liberalism (1993), obra en la que el pensador estadounidense abunda en su idea de extender una concepción política de la justicia al Derecho de los pueblos y a su función reguladora de las relaciones justas entre los pueblos. De cualquier modo, pese a que Rawls admite expresamente la ascendencia que tienen sobre su idea de justicia el contractualismo y el iusnaturalismo kantianos, así como la influencia que ejerce sobre su estudio dedicado al Derecho de gentes la doctrina universalista e iusirenista del Derecho internacional público, veremos hasta qué punto satisfizo o defraudó Rawls con su visión pluralista del orden mundial las expectativas de quienes esperaban que hiciera una defensa firme de la justicia universal y de la democracia cosmopolita.
Participación social y solidaria estudiantil en la Universidad: El punto de vista del profesorado
Authors: Lugo Muñoz Mar , De-Juanas Oliva Ángel
Published: January 2021

En el Marco de Naciones Unidas se promueven políticas para implicar a la universidad en la realidad social mediante iniciativas sociales y solidarias para la transformación social. El espacio universitario ha tomado protagonismo como eje de la acción colectiva universitaria en la comunidad y su papel relevante en la educación, salud, medioambiente y realidad socioeconómica. El propósito del presente estudio es analizar la opinión del profesorado sobre la participación estudiantil en el campo solidario y social dentro del contexto universitario; así como explorar la proyección profesional de los estudiantes hacia la innovación social. Para ello, se realiza un estudio cualitativo en el que se llevan a cabo veinticinco entrevistas a profesorado de las Facultades de Ciencias de la Salud y Ciencias de la Educación de la Universidad de Sevilla. Los resultados apuntan hacia una tendencia clara de los estudiantes de Ciencias de la Salud en colaborar en actividades relacionadas con lo solidario, mientras los que pertenecen a Ciencias de la Educación se muestran más proclives a participar en iniciativas de acción social. Se concluye que la gestión universitaria precisa de mayor compromiso social y solidario con la comunidad; además de fomentar una cultura participativa y ampliar la formación para el desarrollo de competencias acordes a la sostenibilidad, espíritu emprendedor, autonomía e iniciativa profesional.

Authors: Ruiz Revert Marta , García Raga Laura , Ochoa Linacero Belén
Published: January 2021

La formación específica en Pedagogía Hospitalaria es, en la actualidad, una asignatura pendiente en la formación universitaria de los futuros maestros. Desde la óptica de que cualquier maestro, a lo largo de su carrera profesional, puede encontrarse con un alumno/a que enferme, la formación en Pedagogía Hospitalaria no debe estar dirigida exclusivamente a los docentes que desarrollan su carrera profesional dentro del contexto hospitalario, sino a cualquier profesional de la educación que vaya a ejercer en el ámbito educativo. MÉTODO: para analizar si existen necesidades de formación específica en el área de Pedagogía Hospitalaria, se ha aplicado el cuestionario CODEPH-MAGHOS (Ruiz, 2016) a todos los maestros hospitalarios de la Comunidad Valenciana, el cual recoge 95 competencias específicas en materia de Pedagogía Hospitalaria. En el cuestionario, se solicita a los maestros hospitalarios que indiquen cuál es el grado de importancia que ellos le atribuyen a cada competencia para el desempeño profesional de los docentes en las aulas hospitalarias, así como el nivel de adquisición de dicha competencia en su formación universitaria. RESULTADOS: los resultados obtenidos evidencian la falta de formación específica en materia de Pedagogía Hospitalaria que los profesionales de la educación que se encuentran en activo en las aulas hospitalaria de la Comunidad Valenciana corroboran que existe, fundamentalmente formación específica previa a la incorporación de los mismos a las Unidades de Pedagogía Hospitalaria. DISCUSIÓN: El presente estudio aporta datos concluyentes sobre la necesidad de incorporar la formación en Pedagogía Hospitalaria en los grados de Educación. La implementación de la formación de los futuros docentes en Pedagogía Hospitalaria constituye un paso para la mejora de la calidad de vida de los menores hospitalizados.

The objective of this research was to determine the perceptions of Spanish teachers about the competence-based curriculum model (CBCM) introduced by LOE (2006) and maintained by later legislation, ten years after its deployment. Participants were 1408 Spanish Primary and Secondary School teachers (719 women and 689 men). Participants answered an ad hoc questionnaire consisting of a 23-item, five-factor scale (beliefs about the theoretical model, level of implementation of the model, difficulties in implementing the model, resources and professional development). The questionnaire was sent through an on-line application to all Spanish Primary and Secondary Schools. The results show that teachers perceive the importance of curricular change although their expectations are negative regarding its implementation in classrooms, they are committed to the application of the CBCM but there is still a great demand for training and contextual conditions need to be improved. Regarding the factors analyzed, women have a better consideration of the degree of application of teaching strategies or the uniformity in the implementation of CBCM, while men score significantly higher in available resources. Primary School teachers have a more favorable perception in the majority of the items than Secondary School teachers. It is necessary to address all these difficulties observed by teachers if educational reforms are intended to have a real impact on the results of the educational process.

Situs Wonohoyo terletak di dataran aluvial kaki gunungapi Merapi. Berdasarkan pengamatan pedostratigrafi, situs ini tertimbun endapan lahar setebal rata-rata 2 m, dan di bawah endapan lahar ini telah terbentuk Tanah pada taraf yuvenil. Data geolistrik dan pemboran menunjukkan bahwa kawasan situs ini meluas ke arah utara hingga kawasan di utara jalan lingkar utara Desa Plosokuning. Pendekatan sistem perlu diterapkan untuk mengusahakan pengelolaan sumherdaya arkeologi. Berdasarkan masukan data geografi, diperoleh keluaran bahwa situs ini perlu dimasukkan ke dalam kawasan cagar budaya, sebab: (a) kawasan temuan ada di sempadan sungai yang harus dilindungi (b) kawasan ini termasuk subur, sehingga perkembangan permukiman lebih cepat daripada penelitian arkeologi: (c) kawasan ini merupakan daerah rentan bahaya aliran lahar dan gempa humi.
