With the prolonged spread of the new coronavirus infection worldwide and the entry of the super-aged society, smart health care, which combines IT technology for senior health care and the health care industry, is emerging as a solution to the aging problem. The development of non-face-to-face care services using Ai is on a global trend, not in some countries, and the form of care services for the elderly using AI artificial intelligence technology is changing rapidly. The convenience of AI-based care services for the elderly is expected to be highlighted, and the technology and market are expected to develop significantly. As the number of single-person households is increasing, the shortage of welfare workers for the elderly is emerging as a social issue. It is presented as a vision to solve long-term social problems such as the labor shortage of elderly care workers as well as the advantages of convenient care services using IT technology. Therefore, we would like to propose the development direction of care services for the elderly as a case study of care services for the elderly and a countermeasure against the super-aging age.

The reduced production of domestic cosmetics in 2003, compared to last 5 years shows the recession of cosmetics industry. Under this situation, there has been reorganization on the domestic cosmetic market that low-end cosmetic .products become a trend due to the fact that major cosmetic companies also focus on low-end market since the last half year of 2004. However, it does not seem to be a temporal fashion that the extremely low-end cosmetics had an impact wavelength on cosmetics market. It has important meaning for the brand product strategy. This research focused on analysis of market situation and strategy through investigation of requirement and satisfaction on extremely low-end cosmetics in order to keep and improve it, which stimulated depressed cosmetic market.

21 century, Korea enterprise which run business in global market, has rapidly change. So, achievement of international competitive power is very important. IT(Information Telecommunication) Technology is play a leading role in this field. In fact, Korea enormous invest in informational technology field and hold the first place in informational quotient(information super-highway, server computer, mobile networking and firm's web site etc). But, materialization of information management effect consider how to cope with the situation. Korea SMEs(Small and Medium Enterprises) is fundamental in Korea economy. So Korea SMEs must active the international competitive power by information management and advance to a higher position. In conclusion, SMEs of information management is require that SMEs' CEO and CIO are must self-help to in this field. And governments improvement of connected with the related system in these field.

The present world economic powers are divided into three major economic blocks such as EU, NAFTA and North - east Asian Region. In N-E Asian Region, Beijing. Seoul, Tokyo and Shanghai are already bridged economically forming transaction belt with the population of seven hundred million people around the belt. The countries as China, Mongol far - east Russia are rich in natural resources. on the other hand Korea and Japan are superior in technological know-how than that of communist and socialist countries. If we try to be eager to join together with the resource rich countries to the countries of technological know - how as Korea and Japan. The North - east Asian region will be jumping up to the most prosperous and super economic power in the coming years in 2040-2050.

The proliferation of the internet and electronic commerce has given the manufacturers the opportunity of direct marketing. This study analyzes the decision of manufacturers regarding whether to sell the products through independent sales company or to sell the products to the consumer directly. To do this, a new demand function is proposed and sub and super games are modeled and analyzed based on the demand function. By analyzing the Nash equilibria, it is shown that the manufacturers' decision of direct or indirect marketing not only depends on the competitiveness between the products but the absolute and relative marketing capabilities of the manufacturers. It is also shown that, in some cases, the manufactures have incentive to rise the competitiveness between the products to maximize the channel profit.

The study examined the preference and style of consumption of perilla leaves(Perilla frutescens var. japonica Hara), a popular food item in Korea, by consumers in the Daejeon area. Of the respondents 35.2% purchased perilla leaves in a large super-market limited to two to three bundles. Comsumer preferences were to consume the leaves raw or pickled with salt or soy sauce, or use as a fish soup ingredient. The majority of consumers aged 20~29-years-of age preferred to wrap sashimi with perilla leaves. As a side dish, regardless of age, consumers preferred to pan-fried perilla leaves with mincedmeat and perilla leaves.

Recent progress in manufacture of hot and cold rolled steel strip products and their applications were reviewed. The main trend in the technological development has been to meet the customers' requests for quality improvement and cost reduction. The weight reduction to reduce the fuel consumption is the main issue in the automotive industry and, therefore, various steels have been developed to improve formability as well as strength. The steels include super-EDDQ steels, bainitic steels, TRIP steels, etc. In the oil industry, efforts have been focused to improve strength together with either low temperature toughness or HIC/SSCC resistance. The packaging industry is also a highly competitive market, and steel and canmaking companies have worked cooperatively to develop cost-effective canmaking processes as well as high performance steels. This type of cooperation has also been found important in other industries such as the appliance and electronic industries for the benefits of both steelmakers and customers.

Minimum Energy Performance Standard(MEPS) has been adapted in Korea since 2008. For at least 37 kW, IE3 efficiency class motors are now mandatory in Korea. IE4 level regulation is expected in a few years. Foreign companies are already selling IE4 class motors in the market, and the discussions on IE5 have already started. The efficiency standard of variable speed motors is scheduled for publication shortly. Recently, discussions are now beginning to prepare for IE5 in Korea. In this paper, author reviews the policies associated with a high efficent electric motors by reference to both domestic and international standards, and reviews the research direction to prepare for IE5.

Presently, the semiconductor industry has the chronic problem. In the semiconductor industry, it has the semiconductor wafer, a package, the optical filter cut by using the saw blade, the mold, a laser etc. The cutting technique has the difficulty due to the rising of the production cost by the wearing of mold, the poor quality problem due to generated heat at the moment of cutting procedure and curve cutting etc. The goal of this time of national research and development project is develop the apparatus for solving the problem that the existing cutting technique has. The technology is so called waterjet abrasive method. This technology will be mainly applied to cut a semiconductor package and a wafer. Two important things to be considered are ripple effect(in other words, the scale of a market) and simplicity of an application.
