This study investigates aircraft lessor business models by studying cases and interviewing experts to analyze investors and business strategies of aircraft lessor. The results confirm that there is a wide range of investors including institutional investors, financial institutions, insurance companies, corporations, and wealthy individuals for aircraft lessor. Aircraft lessors can be categorized based on its required rate of return (cost of capital) into bank-investing core, institutional investor-investing value-added, and hedge fund-investing opportunistic. Aircraft lessor decides leasing rate by aircraft purchasing price and lessee's credit rating. Core aircraft lessors invest in new aircrafts for new placement or sale-and-leaseback strategy requiring little technical risk in aircraft, value-added lessors invest in middle-aged aircrafts for re-leasing, opportunistic lessors invest in old aircrafts for freighter conversion or part-out strategy requiring high level of expertise. This study provides insights for future Korean aircraft lessor establishment and investment.

This study aimed to convert underutilized moso bamboo into high-value added products such as fences, interior materials, lighting fixtures, and accessories. Green moso bamboo poles with a diameter of approximately 10 cm and a length of approximately 3.7 m were heat treated at 140℃ using a large-scale kiln. The processing time was meticulously adjusted through various stages, including pretreatment (6-8 hours at 60℃), cooking (8-10 hours at 100℃), steaming (26-30 hours at 120℃), heating (4-6 hours at 140℃), and finally, cooling (below 80℃). A meticulously designed heat treatment process has enabled efficient mass production of moso bamboo poles with improved qualities, including minimal splitting, moisture levels below 3%, and a specific gravity of 1.05. The focus of this study was to present the physical and drying properties, such as color, dimensional change, specific gravity, moisture content, and splitting, observed during the heat treatment process.

This study aimed to quality characteristics date for the industrialization of sausage prepared from chicken meat. The sausages were prepared by chicken meat and Jubak powder of CJ1(0%), CJ2(5%), CJ3(10%), CJ4(15%). In the proximate composition of the crude fat content of CJ4 was high and was increased according to Jubak powder addition ratios. Crude protein of CJ1 showed the highest. pH was increased but TBA, WHC, total cell counts were decreased according to Jubak powder addition ratios. WHC was decreased from the initial 46.77% to the final 38.81% according to Jubak powder addition ratios. TBA was increased from initial 0.16-0.19 to 0.2-0.59 at 15 days. Total cell counts in CJ2, CT3 and CJ4 showed the trend to be decreased according to Jubak powder addition ratios. Number of total cell counts of CJ1, CJ4 were increased from initially 2.2 to 8.9, 6.2 at 15 days. Elasticity, hardness, gumminess and cohesiveness of CT4 showed high value. L, a, b were increased according to Jubak powder addition ratios. In the sensory evaluation, Preference for color, overall of CJ1 showed high value. Preference for appearance flavor, taste of CJ2 showed high value. This result can be applied in storage property of chicken meat sausage added with Jubak powder.

As a condition for raising competitive force in the global fashion era that pursues diversity, originality is essential. This research is a study on fashion design able to seek high added value while considering the creative Korean Characters pattern as its motive. Therefore, this research hopes to examine the substantial methods regarding the creation of high added values centered on products utilizing Korean Characters as their motives in the fashion field. The specific research contents intend on, first, studying the formative specialties of Korean Characters; second, examining garment and fashion properties produced with Korean Character as their motive in domestic and foreign fashion shows; and third, understanding the methodology of applying the formation of Korean Characters pattern to fashion design. Hereby, this research suggests the design development regarding the geometrical formation of Korean Characters and the grafting of fashions as the way to inspire the images of domestic fashion brands in the global fashion market and heighten competitive force.

The purpose of this study to fine the mixture of concrete for Top-Down method. As a result, In fresh concrete, slump value and slump-flow value were increased as fly ash concrete(10% ratio). When plasticizer was added 1.5% by weigh of binder in concrete, no fly ash concrete and fly ash concrete(10% ratio) all occurred segregation. And, no fly ash concrete and fly concrete(10% ratio) all showed compressive strength development close plain concrete as increasing plasticizer quantity. Especially, in case of 1.5% plasticizer of binder showed high compressive strength development.

Beauty Art is an act which makes a face beautiful using various methods such as permanent, manicure and make-up. Recently, Beauty Art is recognized as the personal culture expressing the value of beauty and spirit. Therefore, there are growing interests in the comprehensive study of Beauty Art nor only from the beauty industries but also from academia, because Beauty Art is the high value-added field and Is recognized as a style of the dress. The purpose of this study is to open a new view to understand the Nail Art as a fold of experimental plastic art. The arctic expression is added to Beauty Art to develop it from the routine technique of the make-up and hairstyling to creative art. Assemblage is adopted to provide Beauty Art with fine harmonious expression which develop Nail Art into interesting and unique art area. Assemblage meaning compounding or collection is a technique through which three-dimension is added to two-dimension paintings, and which is an expression of an art work by recollection of miscellaneous articles or waste materials. Assemblage is a term which Jean Dubuffet coioned first in order to differentiate collage used by Picaso or Braque. Here, I present Nail Art Designs which applied Jean Dubuffet's works focusing on Automaticity and Happenstantial phenomena of materials, Materialization, and Directness. These features are characteristics of Assemblage which basic frameworks are fantastic collection, accumulation, constructive collection, and object collection.
