Supply chain is the link that moves products between suppliers, manufactures, wholesalers, distribution, retailers and ended consumers. Supply chain management(SCM) is a way to supervise the flow of products, materials and information as they move along the supply chain. In the recent years, Most of the companies are in a hurry the introduction of SCM to obtain international competitiveness. The goal of SCM is to optimize the supply chain, which can not only reduce inventories, but may also create a higher profit margin for finished goods by giving customers exactly what they want. There are four major decision areas (location, production, inventory, transportation) in supply chain management, and there are both strategic and operational elements in each of these decision areas. This paper is concerned with the integrated production planning problem including not only the production cost but also the transportation cost in supply chains, and an efficient algorithm using genetic algorithm and quickest path method is presented to solve the problem.

To accommodate various mobile communication frequency bands, the study of metamaterial antennas have begun since the mid-2000s to solve the Trilemma problem between antenna gain-occupied bandwidth-size. As an adaptive reconfiguration function is required in a multi-array antenna system since 4G, the metamaterial array antenna using low-power variable elements has been used to change the basic structure of the antenna. Recently, reconfigurable intelligent surface (RIS), which is made of metasurface with reconfigurability, has been studied to effectively cope with the randomly varying radio channels and be used for various purposes such as reflection/transmission/modulation. As a result of RIS-related patent information analysis in this study, it was confirmed that most of the patents are metamaterial antennas and metamaterial array antennas, but the metasurface antenna technology was in the early stages. Particularly, as the intelligent metasurface antenna is in a more initial stage, the investment to R&D of RIS is urgent to secure patent competitiveness in B5G and 6G.

Building Information Modeling (BIM) design has been mandatory in Korea since 2016, and it has been gradually expanding in the industry, with a slow attempt to apply it in remodeling constructions. This is because Korea is facing a situation where many buildings are over 30 years old and require remodeling or reconstruction. The remodeling industry is also a growing market, as it saves construction time and cost compared to reconstruction. BIM is an ideal technology element for a competitive remodeling construction, as remodeling constructions face a complicated construction process from the start, including demolition, maintenance, and reinforcement to save the change process. However, there are still limitations in applying BIM to remodeling constructions, due to considerations of the existing building and the complicated requests of the inhabitants. BIM still has technical and environmental limitations for general use. In this study, I analyzed BIM application cases from existing studies and suggest what improvement points should be strengthened.

In the study of the mechanism of labor motivation as a determinant of economic security of the enterprise in competitive conditions, it was found that motivation is determinant in creating the conditions for production and ensuring the active functioning of the enterprise. It is substantiated that the motivational mechanism is the presence of a system of levers, incentives, measures and other elements for economic and administrative incentives for employees, which are used for incentives to work, increase productivity and safety, and more. The motivational mechanism plays an important role in ensuring the economic security of the enterprise and at the same time is a lever to increase competitiveness in the market. The functions of the mechanism of labor motivation are singled out, among which: explanatory-substantiating, regulative, communicative, socialization, regulating. The stages of occurrence of the motive for the employee are classified. The interrelation of motives and incentives in the mechanism of labor motivation as determinants of economic security of the enterprise in competitive conditions is proved. It is proved that the mechanism of labor motivation as a determinant of economic security of the enterprise in competitive conditions should be aimed at: assistance in forming and achieving goals and objectives of the enterprise and achieving balance and equilibrium of economic goals and social responsibility of the enterprise; ensuring close cooperation between management and employees of the enterprise; focus on building a flexible mechanism; transition to a democratic style of governance and involvement of employees in decision-making.

In modern society, culture is an important factor to form a country's image and identity and a representative content to generate revenue. Culture is a keyword to design life in the 21st century and has become competitiveness between countries. As a cultural content with international competitiveness, this study performed textile design development with the use of relics from the Tomb of King Muryeong, which is the tumulus of King Muryeong who was the 25th king of Baekje among Korean history. The developed design could be applied to the production of various fashion cultural products such as clothes, scarf, neck-tie, and bag. The process for the design development was carried out as follows: As a first step, this study found basis as a cultural content with a global sense that could form the historical value of the Tomb of King Muryeong and gain global sympathy of people all over the world through literature reviews. As a second step, this study examined the current state that traditional Korean elements were used as a fashion cultural products. As a third step, this study analyzed the current state and problems of fashion cultural products using relics from the Tomb of King Muryeong through field survey. As a final step, this study planned the concept of design with the use of diadem ornaments, earring, sword, stone guardian animal, and bricks with lotus-flower design from the tomb of King Muryeong. And these developed 6 textile designs could be applied to the production of various fashion cultural products.

The purpose of this study was to examine the uniform image of Korean herbal cosmetic brands amongst Korean and Chinese consumers. This study would enable us to explore a BI strategy to enhance international competitiveness of Korean herbal cosmetics brands. The results were as follows. The key words of BI pursued by Sulwhasoo were dignified, novel, graceful, soft, gaily, natural, Korean, modern, and international. Korean people felt that the uniform was graceful and soft, which accorded with Sulwhasoo BI, but also it was trite and dingy, indicating a negative and opposing image. On the other hand, Chinese people felt that the uniform was dignified, novel, graceful, natural, modern, and international, indicating that it matched with Sulwhasoo BI. In The History of Whoo, the key words of BI pursued by the brand were precious, soft, gorgeous, gaily, and natural. The Koreans felt that the uniform was intelligent, and decent, but conversely, it was also austere and dingy, indicating a negative image. The Chinese felt that the uniform was common, hard, austere, dingy, and unnatural, indicating an opposing image to BI. Finally, a uniform design was developed to improve on its problems, establish The History of Whoo's brand identity, and its brand image. First of all, 'The Quintessence : noble passion' was set up as a developmental concept. The textiles, clothing, and accessories were designed using the symbolic elements from The History of Whoo as a motif. Uniforms were developed for spring, fall, and summer.
