The emergence of ‘Transeurasian’ language families in Northeast Asia as viewed from archaeological evidence

From a linguistic standpoint, Proto-Japonic and Proto-Koreanic are assumed to have split off the Transeurasian languages in southern Manchuria. The linguistic idea that Proto-Japonic came earlier than Proto-Koreanic in the chronological scheme means that the Proto-Japonic language first entered the Korean Peninsula, and from there spread to the Japanese archipelago at the beginning of the Yayoi period, around the 9th century BC, while the arrival of Proto-Koreanic in southern Korea is associated with the spread of the rolled rim vessel culture around the 5th century BC. The genealogical sequence of the Pianpu, Mumun and Yayoi cultures, which shared the same pottery production techniques, indicates the spread of Proto-Japonic. On the other hand, migrants moved from Liaodong to the Korean Peninsula and established the rolled rim vessel culture. This population movement was likely due to social and political reasons as the Yan state enlarged its territory eastward. The Proto-Koreanic of the rolled rim vessel culture later spread to the Korean Peninsula and gradually drove out Proto-Japonic, becoming the predecessor of the Koreanic. In this paper, I examine the spread of Proto-Japonic and Proto-Koreanic in Northeast Asia based on archaeological evidence, focusing especially on the genealogy of pottery styles and pottery production techniques.

Effect of Production Technique on Pilsner-Style Non-Alcoholic Beer (NAB) Chemistry and Flavor

The sensory, volatile, and physiochemical profiles of nineteen commercial non-alcoholic pilsner-style beers produced by different production techniques were analyzed and compared with a dry-hopped non-alcoholic IPA. NABs made only with either physical dealcoholization or restricted fermentations differed significantly in chemistry and flavor. Generally, NABs produced by restricted fermentations were the most worty, thick, and sweet, whereas NABs that were physically dealcoholized had the lowest taste/aroma intensities and were the sourest, most thin, and least sweet. Interestingly, the method of dealcoholization had a minor impact on the flavor profile. The use of maltose intolerant yeast as well as the implementation of combined treatments, such as blending dealcoholized beer with beer containing alcohol, were the techniques found to produce NABs with more harmonious and multifaceted chemical and flavor profiles. NABs with increased hop aroma volatiles were the most harmonious, particularly highlighted by the NA IPA reference. Even though dry-hopped character might be atypical for pilsner-style beer, dry-hopping appears as a simple application to produce NABs with more harmonious flavor.

Production Techniques of Metallic Foams in Lightweight Materials

Lightweight materials were needed in many different areas, especially in order to reduce the required energy in areas such as automotive and aerospace industries. Metallic foams attract attention in lightweight material applications due to their unique properties. The pores in its structure provide advantages in many applications, both structural and functional by promising both ultra-lightweight construction, energy absorption, and damping insulation. Production techniques of metallic foams can generally be classified as liquid, solid, gas, and ionic state production according to the physical state of the metal at the beginning of the process. The production technique should be chosen according to the usage area and desired properties of the metallic foam and the suitability in terms of cost and sustainability of production. For this reason, the details of the production techniques should be known and the products that can be obtained and their properties should be understood. In this respect, this chapter emphasizes the production methods from past to present.

Agroecology and Sustainable Development in Africa

The term agroecology is not new, since it first appeared in scientific literature in the 1930s. In recent years, it seems to have enjoyed increasing success. It constitutes a new sustainable path for rural development and adaptation to climate change. This study will allow us to assess the impacts of this mode of production and agroecological production techniques.

Generalised Typesets in Experimental Ceramics: Widening Applicability and Maximizing Cross-cultural Assessments

Investigations tackling the production techniques used by ancient potters often rely upon experimental archaeology to clarify the relationship between surface morphology, surface topography, and the techniques, methods, and gestures used in the potting process. These experimental archaeology programmes focus on creating collections of experimental vessels to compare against archaeologicallyrecovered vessels, thus allowing production techniques to be identified. Often times, however, the typesets generated are designed to address a specific intersection of qualities; replica vessels adhere to a tight range of shapes, dimensions, paste recipes, and/or forming techniques. As such, the applicability of those typesets remains narrow and context-specific. How, then, can researchers tackle assemblages with diverse vessel types? Or contexts composed of competing potting traditions? Or contexts with significant proportions of vessels from many different origins? This paper presents a new approach to the way that experimental typesets are designed, developed specifically to address the problem of reliably identifying forming techniques across multiple assemblages. By focusing on accommodating common geometric possibilities of vessel shapes, a generalised typeset can allow individuals to make use of well-documented experimental data. The typeset for the Tracing the Potter’s Wheel project was designed for broad applicability, and has been made freely accessible as a reference collection. Through the creation of and comparison against a generalised typeset, heterogeneous assemblages can be better understood and resources can be directed toward answering specific questions. This paper presents the theoretical foundations supporting the concept of a generalised typeset, as well as the practice of using a generalised typeset for analysis.

Desfragmentación edáfica, social y cerámica. Proyecto artístico centrado en el diseño de platos a partir de restos cerámicos encontrados en el agro de Casabermeja, Antequera y Orce

The main objective of this study is the creation of an artistic ceramic project that reflects the current situation of the rural world as a consequence of industrial agriculture. Current agricultural and livestock production systems have negative environmental consequences, such as erosion and pollution, and cultural consequences, such as rural exodus or the extinction of indigenous germplasm. Through the study of the rural world in the municipalities of Casabermeja, Antequera and Orce, it has been possible to verify the detriment of these lands and their culture and, at the same time, the remains of ceramic plates found in these lands reflect this reality. The methodology used is theoretical-practical: through scientific references, the destruction of pre-industrial agricultural practices is exposed against industrial agriculture; experimentation with agricultural production techniques, both traditional and modern, show their compatibility; and, finally, artistic research, which recovers ceramic remains from the past to design three plates. The artistic work is proposed as an information and awareness means of a world problem, showing the compatibility between production and biodiversity, Nature as a source of culture, and human society as a dependent part of Nature. Este estudio tiene como objetivo fundamental la creación de un proyecto artístico de cerámica que refleje la situación actual del mundo rural como consecuencia de la agricultura industrial. Los actuales sistemas de producción agrícola y ganadera tienen consecuencias negativas medioambientales como la erosión y la contaminación, y culturales como el éxodo rural o la extinción de germoplasma autóctono. A través del estudio del mundo rural en los municipios de Casabermeja, Antequera y Orce, se ha podido comprobar el detrimento de estas tierras y su cultura y, al mismo tiempo, en los restos de platos cerámicos hallados en estos terrenos se encuentra el reflejo de esta realidad. La metodología usada es teórico-práctica: mediante referentes científicos se expone la destrucción de las prácticas agropecuarias preindustriales frente a la agricultura industrial; la experimentación con técnicas de producción agrícola, tanto tradicionales como modernas, evidencian su compatibilidad; y, finalmente, la investigación artística, que recupera restos cerámicos del pasado para diseñar tres platos. La obra artística se propone como medio divulgativo y de concienciación de un problema mundial, evidenciando la compatibilidad entre producción y biodiversidad, la Naturaleza como fuente de cultura, y la sociedad humana como parte dependiente de la Naturaleza.
