At the beginning of the emergence of Covid-19, there was panic buying in Indonesia which caused an unusual situation in supply management. Although the handling of this epidemic has entered a "new normal", the availability of stocks of electronics, automotive, pharmaceuticals, food, and others is running low and out of control, so supply chain management is needed. The purpose of this article is to try to see the extent of the transformation in supply and demand in Indonesia. With this in-depth literature, the supply chain model is likely to transform globally, given that many companies are confused about management being unable to cope with drastic changes in the market. The demand patterns over the past period indicate a shift from offline to online storefronts. Even though it has now entered a transition to a new normal and shopping outlets are slowly opening up, online shopping or demand patterns are predicted to last a long time. Therefore, supply chain actors, especially farmers, logistics entrepreneurs, and shipping services, inevitably have to be able to quickly adapt to changing patterns in Indonesia. There is an imbalance between the demand and supply sides. Food supply chains tend to be unique in comparison to the supply chains of other products and services.

The shared autonomous mobility-on-demand (AMoD) system is a promising business model in the coming future which provides a more efficient and affordable urban travel mode. However, to maintain the efficient operation of AMoD and address the demand and supply mismatching, a good rebalancing strategy is required. This paper proposes a reinforcement learning-based rebalancing strategy to minimize passengers’ waiting in a shared AMoD system. The state is defined as the nearby supply and demand information of a vehicle. The action is defined as moving to a nearby area with eight different directions or staying idle. A 4.6 4.4 km2 region in Cambridge, Massachusetts, is used as the case study. We trained and tested the rebalancing strategy in two different demand patterns: random and first-mile. Results show the proposed method can reduce passenger’s waiting time by 7% for random demand patterns and 10% for first-mile demand patterns.

The techniques provided by spatial analysis have become a great ally of tourist planning as they allow the carrying out of exhaustive territorial analyses. The greater availability of georeferenced databases together with the more and more extensive use of GIS (Geographic Information Systems) is materialising in the proliferation of studies analysing the distribution patterns of tourist territories. The present study uses these techniques to study the degree of equilibrium in the distribution of places and its level of occupation in a region where the use of expansionary policies of growth of the tourism sector has been able to cause a strong imbalance in said activity, i.e., the case of the region of Extremadura. To verify this, both global contrasts, global Moran’s I and G (d) of Getis and Ord, are used, as well as local contrasts, to map LISA (Local Indicators of Spatial Association). The results obtained confirm the existence of strong imbalances in the effectiveness of the places created while allowing the identification of different clusters of high and low values. These findings represent an important output for the strategic planning of the territory in order to develop a strategy that allows the sustainable tourism development of the territory.

Planted forests have grown substantially in Brazil, especially in states such as Goias. While they may compete with native forest areas, planted forests also present themselves as economically viable solutions for the recovery of degraded areas. This study presents the market of wood in the Brazilian state of Goias analyzing the interaction between supply and demand curves of the product in a partial equilibrium analysis. In this sense, it is essential to understand the spatial issue to offer production by planning the transaction costs related to transportation. Therefore, the distribution of companies is linked to the production chain, mapped by means of labor market bases (Ministry of Labor), wood production (IBGE) and other industry data. The spatial analysis of the planted forest area (silviculture) in Goias between 2000 and 2016 was based on data from the time series, from mapping provided by the MapBiomas Project. In Goias, considering all sectors of the forest production chain, in 2015 alone, revenues exceeded US$ 1.24 billion and public collections US$ 24 million, employing more than 36 thousand people in 7 thousand firms. Thus, it is fundamental to understand this process, identifying the main determinants of planted forests, through statistical and spatial analysis. From a spatial point of view, planted forests and companies involved in wood production are relatively spread throughout the state, except for the state capital of Goiania, which has a large number of timber trade and manufacturing firms.

The tombs of Mt. Geumseong in the Uiseong area represented an influential political entity that existed in northern Silla during the period of Three Kingdoms. Created at the feet of Mt. Geumseong, Tapri, Hakmiri, and Daeriri are collectively called the tombs of Mt. Geumseong. Interest in the ornaments found in the tombs has continued from the Goguryeo-style gilt bronze crown found in a tomb of Tapri in 1960 to the gilt bronze official hat found in a tomb of Daeriri recently. The materials of ornaments in the tombs of Mt. Geumseong are the same as those excavated in old tombs around Silla, which means that the appearance and development of Silla ornaments in the tombs of Mt. Geumseong was the result of Silla s grant of ornament system that was operated across its territory. The grant of ornament system is an archeological concept to explain the supply and demand patterns of ornaments between the central and local groups of Silla from the perspective of political dynamics. The system was based on the premise that there were the supply and demand sides or the central and local groups in Silla. It was thus predicted that the supply and demand process at the bottom of grant of ornaments was a dual structure of mutual reactions between the two groups. The investigator interpreted the characteristics of Silla s ornaments found in the tombs of Mt. Geumseong based on this. The ornament materials found in the tombs of Mt. Geumseong were categorized into the Goguryeo style, Gyeongju style, and local creations. The use of Goguryeo-style ornaments by the group of tombs of Mt. Geumseong was the result of mutual compromise between the central and local groups of Silla. The supply and demand of Goguryeo-style ornaments developed based on mutual compromise between central Silla, which was conscious of its diplomatic relations with Goguryeo, and the group of tombs of Mt. Geumseong with its geopoliticaluniqueness as a frontier. Later, the percentage of Gyeongju-style ornaments rose in the group of tombs of Mt. Geumseong. A symbolic event took place as the Goguryeo-style Woomo-shaped crown was replaced with the Gyeongju-style Suji-shaped one. It was the result of mutual reactions between the pressure from central Silla to choose Gyeongju-style ornaments according to its anti-Goguryeo policy and the emphasis on pan-Silla identity in the group of tombs of Mt. Geumseong. Ornaments made locally appeared during the period when the percentage of Gyeongju-style ornaments increased. They started with the repair of damaged ornaments and reached the level of making a complete work such as gilt bronze official hats and Isiks. They were the reproduced versions of central Silla s ornaments by the group of tombs of Mt. Geumseong, which is why their creation is not considered to represent the group s independence against pan-Silla identity. The group s reproduction of ornaments beyond the acceptance and acquisition of ornaments from the central region was the result of its active reactions to reinforce pan-Silla identity.
