In pre-modern Korea, paper was renowned for its white glossy surface and cloth-like strength, becoming an important item in both tributary exchanges and private trade. The unique material of the tak tree and related technical innovations, including toch’im, the repeated beating of just-produced paper that provides sizing and fulling effects, were crucial to this fame. However, the scholar-officials who integrated papermaking into the state production system in order to meet administrative and tributary needs initially made toch’im corvée and then penal labor, thereby dismissing it as simple toil. They were not alone, though, in denigrating a form of manual labor. Historiographies of modern science and technology are generally silent about such work, focusing instead on how we invented the human out of drudgery. However, papermakers in late Chosŏn Korea (the eighteenth and nineteenth centuries) chose to identify their artisanship with toch’im and eventually succeeded in securing recognition for that technique as a highly paid specialty. By examining this skilling of toch’im, this paper seeks to change the historiographical silence about toil. It overcomes the archival silence that accompanies manual skills by tracing toch’im’s contours through its changing locations and associations in society’s changing social and material networks, revealing paper artisans’ social techniques, or everyday politics that eventually dignified their laborious technique. Paper artisans’ changing relationships with tak barks, tools and facilities, central and local authorities, farmers, merchants, and scholar-officials reveal how such social skilling was made in late Chosŏn Korea, where papermaking became a most successful industry. This tracing of toch’im re-situates creative toil and everyday politics of artisanal hands in the interconnected transformation of social relations, craft, and knowledge practices.

Abstract Production rate decline is one of the most common challenges in production engineering. Obviously, the first step to overcome this challenge is to understand its main reason. In this article a new approach is developed which can be used to compare the effectiveness of artificial lifting and well stimulation. The method is based on a couple of charts which summarize the results of integrated simulation of formation and well-column. In the first graph, called FPI curve, production rate is drawn as a function of productivity index. Some important points are also specified on this diagram which are current state, production rate at maximum possible productivity index and production rate when the well is equipped with a pump or gas lifting. In the second graph derivative of production rate of different wells are drawn as a function of productivity index. The analysis of three actual wells with conventional IPR-TPR curves and also our suggested curves is discussed in this paper. It is seen that the introduced approach can be used as a powerful tool to predict the effectiveness of well stimulation and artificial lifting and make a clear comparison between them.

Usage Area

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.
