Purpose: After using the Internet, the world is changing through several paradigms, and the retail industry, which is essential to living in the world, is also changing rapidly. In this review paper, the requirements that the retail industry should consider and prepare in accordance with the rapidly changing paradigm were reviewed according to the current situation of the times. Research design, data, and methodology: It is a review of technological development using PRISMA flow diagram, retail change, and necessity in April 2022, and a review of the digital environment to be applied to the retail industry in the future. Results As the current situation and changes of retail, and the development of IT technology, reviews on the retail business applying the 4th Industrial Revolution, the Internet of Things and artificial intelligence were collected, and the direction of the retail industry was suggested. Conclusions: The direction for the retail industry in preparation for developing technologies was presented. In addition, this study is a review paper that suggests the need for research on active introduction of new technologies to the beauty market that is very close to human life and economically helpful as IT technology for the 4th industrial revolution develops rapidly.

Digital Manufacturing is a technology facilitating effective developments and agile productions of the product via digital computer models representing physical and logical schema and the behavior of the real manufacturing systems including manufacturing resources, environments and products. For the successful application of this technology, a digital factory as a well-designed and an integrated environment is essential. In this paper, we constructed the sophisticated digital factory of a Korean automotive company's body shop, and conducted precise simulations of unit cell, lines and the whole factory for the collision check, the production flow analysis and the off-line programming. We expect that this digital factory of the body shop helps us achieve great savings in time and cost for many manufacturing preparation activities of the new car development.

To obtain accurate and repeatable analyses using NIR technology it is important to select an NIR instrument and / or its sample presentation attachments which allow the operator to minimize sampling errors without compromising the benefits of NIR analysis -namely rapid, low cost, minimal sample preparation, minimal structural facilities, minimal hazards. For each sample type and consistency there may be different optimal combinations of instrument, sample presentation attachment, and sample preparation. This paper will consider options available to NIR users in the area of plant and soil analysis and evaluate the potential benefits and disadvantages of crop nutrient diagnoses using laboratory based and airborne imaging techniques.

Carbon nanotubes (CNTs) have high Young's modulus, low density, and excellent electrical and thermal properties, which make them ideal fillers for polymer composites. Homogeneous dispersion of CNTs in a polymer matrix plays a crucial role in the preparation of polymer composites based on interfacial interactions between CNTs and the polymer matrix. The addition of a small amount of CNTs strongly improves the electrical, thermal, and mechanical properties of the composites. This paper aims to review the processing technology and improvement of properties of CNT-reinforced polymer composites.

In this paper, to improve the efficiency of pressurized pneumatic grit conveying for ship block open blasting process. Pressurized pneumatic grit conveying is defined as the transportation of grit(abrasive) in a compressed air flow. Total Pressure loss in flexible hose for pneumatic conveying is sum of pressure losses due to gas and grit and needle type pressure transmitter for measured pressure loss. haracteristics of grit open blasting by pneumatic conveying were studied experimentally. Studies variables were blasting nozzle ID, length and ID of flexible hose, grit flow rate, flow rate and pressure of transport air. It was experimentally proved that optimal open blasting condition and cost effective operation regarding grit blasting, obtaining a high qulity surface preparation(Sa $2^{\frac{1}{2}}$).

In this paper, it was investigated that the pattern recognition of multiplication environment of lactic acid bacteria in the process of curd yogurt preparation using household fermentation system, which was manufactured by combining incubator with sensor module, data processing circuit and computer. It will be sufficiently applicable to determine the maximum ratio of the amount of air to mixed milk for preparation of high quality yogurt.

This paper analyzed the current status of universal design in the Republic of Korea (Korea) and Japan. In the case of Japan, the aged society or the super aged society has been preparing from 1985 when the aging rate was 10%. Japan's activity to prepare it became promoted during 1990's when per capita Gross National Income (GNI) was $$20,000{\sim}40,000$. In Korea, the preparation for the aging society such as physical environment, barrier free buildings or traffic systems, economic support and investigation or survey is not yet sufficient. Korea must start preparation for an aged society, possibly and quickly. And it needs to prepare until 2026, when the aging rate will be 20%. To prepare a barrier free and an aged society must consider both aging and economic status.

Nanoimprint lithography (NIL) is a novel method to fabricate nanometer scale patterns. It is a simple process with low cost, high throughput and high resolution. NIL process creates patterns by the mechanical deformation of imprint resist and physical contact process. This physical contact process causes the stiction between the resist and the stamp. Stiction becomes a key issue especially in the stamps including narrow pattern size and wide area during NIL process development. The antistiction layer coating using fluorocarbon is very effective to prevent this problem and ensure successful NIL. In this paper, the concept of antistiction coating is explained and different preparation methods for nanoimprinting are briefly discussed.

The development of new improved type of dielectric materials on the conception of multiphase structure has been carried out in this paper. Metal alkoxides solutions were used for application of thin film by electrophoretic deposition technique. We succeeded in preparation of amorphous and composite dielectric films from Al alkoxides. Specific features of the preparation technique were considered. Microstructure of the films was examined as well as their dielectric properties. TEM analyses reveals that films deposited from aging sols and heat-treated at temperatures as low as $400^{\circ}C$ contain small whiskers of ${\delta}-Al_2O_3$.
