A very extensive literature review presents the possibilities and needs of using, in endodontics, the alloys commonly known as nitinol. Nitinol, as the most modern group of engineering materials used to develop root canals, is equilibrium nickel and titanium alloys in terms of the elements’ atomic concentration, or very similar. The main audience of this paper is engineers, tool designers and manufacturers, PhD students, and students of materials and manufacturing engineering but this article can also certainly be used by dentists. The paper aims to present a full material science characterization of the structure and properties of nitinol alloys and to discuss all structural phenomena that determine the performance properties of these alloys, including those applied to manufacture the endodontic tools. The paper presents the selection of these alloys’ chemical composition and processing conditions and their importance in the endodontic treatment of teeth. The results of laboratory studies on the analysis of changes during the sterilization of endodontic instruments made of nitinol alloys are also included. The summary of all the literature analyses is an SWOT analysis of strengths, weaknesses, opportunities, and threats, and is a forecast of the development strategy of this material in a specific application such as endodontics.

This article aims to analyze the policy strategies implemented for the commercial shipping development of the Apo Dock in Jayapura port to improve port performance towards strengthening the sea highway program. Apo Dock as a shipping commercial in Jayapura port has weaknesses as identified by the observation and the study of primary data. These weaknesses have resulted in price disparities for the Papua province as port functions well as a logistical hub. Based on the Strengthen-Weakness-Opportunity-Threats (SWOT) analysis results, it was concluded that the Apo Dock performance as the Jayapura Port Commercial Route was in quota I with a position (0.83; 1.44). The strategy used by Jayapura port to develop commercial shipping to be more efficient in accordance with its function as the strength-opportunity (SO) strategy. The SO strategy strengthens the commercial shipping function as a support base for the economic development centers and a government supporter in MP3EI, the commercial port facilities and infrastructure development were established in order to support all port activities and efficiency, and develop hinterland areas to maximize the busy and crowded commercial shipping hub.

Background: The selection of materials for the production of multilayer insoles for diabetic feet is a difficult task owing to the lack of technical information about these materials. Therefore, objective criteria were established for the selection of these materials. Methods: Mechanical- and comfort-related tests for the mechanical characterization of different materials and their combinations were considered. These tests were conducted according to standardized test methods for polymeric cellular materials. Results: Criteria for the use of cellular materials were obtained. The properties of accommodation, cushioning, and filling materials were established and the most adequate polymer nature for each of the three applications was identified. Variables that affect the properties of these material combinations were studied. Conclusions: These test results will allow podiatrists to select insoles in a more objective way, thus achieving a more successful treatment for diabetic foot-related injuries.

The purpose of this study is to examine the factors that play a role in the development of pempek quality favored by consumers and to study internal and external factors that influence the development of pempek processing industry and its implications for strengths, weaknesses, opportunities and threats as well as formulate alternative development strategies for Pempek industry.The sampling technique used in this study is simple random sampling with a sample area of 95 respondents consisting of 10 pempek processors (producers) and 85 consumers. Data processing is done by using factor analysis to know the dominant factor of pempek industry development. SWOT analysis is used to determine the development strategy of the pempek industry.The results showed that the factors that play an important role in the development of pempek industry are organoleptic factors consisting of taste, color, softness and aroma; Consumer prices, food hygiene and safety with regard to physical quality, chemical quality, shelf life and strategic location. Pempek industrial development strategy that must be done is by the application of practical and efficient technology, excellent products, hygiene and security, extension of marketing network through cooperation with marketing agents both at homeland and foreign countries, cooperation, restaurant, retail and supermarket, promotional strategy improved through Advertising, leaflets, radio, television, internet and publicity.

The need to study the development of business entities in the context of individual categories of industrial parks is connected with different concepts of their development and territorial expansion. The suggested methodological approach to assessment of sustainability level of the business firms functioning in the system of industrial parks includes the following main stages: grouping of industrial parks and the selection of representatives of the groups; rating assessment of stability level of firms functioning in the system of industrial parks; grouping of businesses by the level of sustainability. The technique was tested on data from 150 industrial parks. The results of the implementation of the suggested approach show that more vulnerable positions are typical of businesses operating as part of industrial parks as “greenfield” companies. At the same time, the highest proportion of businesses with a low stability level is typical of developing parks, which indicates the need to expand the range of incentives for these businesses. The most stable cluster of entrepreneurs is business entities of developing parks such as “brownfield” companies. Entrepreneurs operating within developed parks as “brownfield” firms are characterized by a satisfactory level of sustainability. The proportion of entrepreneurial structures with a low stability level remains quite high, which indicates the need to adapt the development strategy of business entities in the system of such structures. The results obtained made it possible to identify the most vulnerable groups to risks, business entities and can be used to form a strategy for their sustainable development in the system of industrial parks.
