기능성 화장품이라 함은 피부미백, 주름개선, 자외선차단 등 특정한 기능을 가지고 피부에 효과를 주는 화장품을 말했다. 그런데 2017년 이후 기능성 화장품의 품목이 확대되었다. 대한민국의 기능성 화장품 산업은 미백, 주름, 자외선 차단 제품에 머물고 새로운 기능성 제품의 개발은 미비한 상태이다. 또한 코스메슈티컬과 메디컬 화장품을 비롯한 고기능성 화장품도 아직 정립되지 않은 상태이다. 그리고 국외에 수출실적 순위는 프랑스가 가장 높았고 미국, 독일 순으로 나타났다. 프랑스는 화장품 산업 업계 1위 국가답게 바이오 공업과 기능성 소재에서 메커니즘 중심의 기능성 화장품을 강조하고 있고 미국은 럭셔리 프리미엄 제품에 수요도가 높았으며 독일은 바이오 하이테크 기술에 주목하고 있다. 이처럼 한국도 신흥 산업에 적용할 수 있는 기능성 화장품들의 새로운 소재들을 개발하고 정치와 경제가 뒷받침 되어 연구에 더 집중할 수 있는 환경이 갖춰져 다양한 기능성 화장품 산업 등을 발전시켜 나아가야 할 것이다.

Objective: This experiment is to study how elderly group and their various lifestyles interact with health functional foods, according to their selection behavior. Different lifestyles will be observed closely, as well as how different health conditions and consumer involvements will affect critical decision making in selecting health functional foods. Method: Theories and discoveries from original advanced research were compared parallel to the new study. Results: First, cluster analysis and exploratory analysis were performed amongst different elder lifestyles. Lifestyle exploratory analysis was used for healthy, unique, leisure, and economical-style elders. Cluster analysis was used for material trend oriented, health oriented, complacent oriented-style elders. Health Functional Foods' selection trait Exploratory Factor Analysis showed that product's originality (function, uniqueness, specialty, compatibility, distributor, expiration date), quality (amount, daily dose, visual representation, accessibility, portability, natural ingredients), and popularity (product container, brand image, taste and smell, advertised product, domestic or import, well-known function) were the three main causes. Secondly, the amount of benefits for the elderly group health lifestyle were affected by 'Interest in health', 'Notability of the health functional food', and 'Functionality approved mark'. Specifically, the importance of, 'Interest in health', 'Notability of health functional food', and 'Functionality approved mark' were noticeably high within health oriented elders. Lastly, after examining the data from elder lifestyle's relationship with health functional food selection trait, all three different results showed equal importance. If you closely examine material trend oriented elderly group, selection trait showed distinctively high regards in 'Fundamental Attribute', 'Typical Attribute', and 'Cognitive Attribute'. Health oriented elders showed their distinctively high regards in 'Natural Attribute', and less consideration in 'Typical Attribute' and 'Cognitive Attribute'. Complacent oriented-style elderly group showed less focus on 'Fundamental Attribute', and even less in 'Typical Attribute', and 'Cognitive Attribute'. Health oriented elderly group concluded with above data from the fact that they showed most importance and involvement in health beneficial products that are scientifically proven. Material trend oriented elderly group showed balanced traits in their concluded data, showing that they prefer function, safety, as well as the brand image and their reputation. Also, they consider the products' outer elements, such as design and product name, in order to sense inner functions. Conclusion: So, Silver Business corporations must develop products to fulfill the market demands, and strategize marketing plans to better target the correct audience.

This study aims to develop a multi-functional cage for dogs as a house to reduce their anxiety when they go out using cages. This study investigates the types and characteristics of cages and cage preference by surveying men and women in their 20s who use them. The cage product reviews are also analyzed. The research results are as follows: First, domestic dog cages are classified into crate, shoulder, cross (sling bag), backpack, carrier, and stroller types. The crate type is easy to clean and can be used as a house, but it is bulky and therefore inconvenient to carry when using public transportation. The shoulder type is a fabric material with good air permeability but has the disadvantage of being easily soiled. It can be used as a house and is light weight, making it convenient when using public transportation. Second, as a result of consumer research, respondents prefer the shoulder-type fabric over the crate-type plastic material. Third, from the shoulder-type product review, the shape stability, companion dogs' psychological safety, the wearability of companions, and management convenience are derived. Fourth, based on the survey results, a multi-functional cage is developed taking into account the companion dog, companion person, and functional factors.

This study was conducted to determine the nutritional value of domestic cherry tomato varieties (Summerking, Qutiquti, and Minichal). The levels of amino acids, amino acid derivatives, and ${\gamma}-aminobutyric-acid$ (GABA) were analyzed using ion chromatography. In domestic cherry tomatoes, eighteen free amino acids were found including L-glutamic acid (L-Glu), L-glutamine (L-Gln), and L-aspartic acid (L-Asp). L-Glu was the most abundant amino acid, ranging from 1,533.17 mg/100 g to 1,920.65 mg/100 g (dry weight). The next abundant amino acids were L-Gln, ranging from 784.68 mg/100 g to 1,164.36 mg/100 g and L-Asp, ranging from 320.73 mg/100 g to 387.22 mg/100 g. Domestic cherry tomatoes contained eight essential amino acids except tryptophan and the total essential amino acid content was 297.30~432.43 mg/100 g (dry weight), which was 8.92~10.61% of total free amino acid. Several amino acid derivatives were found: L-carnitine (L-Car), hydroxylysine (Hyl), o-phosphoethanolamine (o-Pea), phosphoserine (p-Ser), ${\beta}-alanine$ (${\beta}-Ala$), N-methyl-histidine (Me-His), ethanolamine ($EtNH_2$), and L-citrulline (L-Cit). L-Car, transporting long-chain fatty acid into mitocondrial matrix, was the most abundant amino acid derivative in all domestic cherry tomatoes. A high level of GABA (313.18~638.57 mg/100 g), known as a neurotransmitter, was also found in all three domestic cherry tomatoes. These results revealed that domestic cherry tomatoes have a good balance of nutrient and bioactive compounds. Therefore, cherry tomatoes can be used as a functional food material.

This study investigates the actual domestic and overseas cyclewear wearing conditions for male high school cyclists. The study results provide factors and degree of dissatisfaction as basic data for cyclewear development. This study was conducted on 35 male high school cyclists (freshman to seniors) by a questionnaire and interview method. Study results were: Male high school cyclists considered functionality as most important when they bought cyclewear and the brand they most often bought was a cheap domestic brand. Dissatisfaction with the crotch, thigh circumference and minimum leg circumference was higher than other parts during wearing. A cyclist is more sensitive to wear because they require more lower body motion than other parts. Cyclewear should be: less transformed even by frequent laundering, made of breathable material and use a sewing technique that minimizes air resistance and increases fit the body. Functional pads ergonomically designed with high tactile materials should be developed to prevent 'saddle sore' and groin soreness region that happens because of a lower body bending posture when cycling. A follow-up study is recommended to further develop excellence in cyclewear functionality and dimension suitability for male high school cyclists through the size system.

The Tuck, an important component of modem clothing design, was analyzed through various sources of literature comprised chiefly of domestic and imported fashion magazines from 2000 to 2003. The results were as follows: 1) The Tuck was organized in horizontal, perpendicular, oblique and radial directions. Application methods included repetition, gradation, radial arrangement, sequence and alternation of individual lines. 2) The Tuck was found in a variety of forms and uses. But due to structural characteristics, its function is more psychological and aesthetic than functional. The aesthetic properties of the Tuck included rhythm, optical illusion, abstraction, and material. The structural property of the Tuck occasionally substituted bust or waist darts. 3) The individuality and originality of the Tuck was used in unpredictable ways to give spatial ornamentality and emphasis on material. This enabled aesthetically unique designs to arise. To summarize, the Tuck, a component of clothing design as a formative art, was used in a variety of methods towards developing creative clothing design.

The internet of things (IoT) technology is a key component for the advent of 4^th industrial revolution, which is the network of home appliances, infrastructures, and vehicles to remotely investigate these systems. For the operation of compact IoT devices, batteries are widely used as electric power, and the limited lifetime of batteries inevitably leads to periodic replacement. Magneto-mechano-electric (MME) generators may be alternatives to batteries inside the IoT devices by converting stray magnetic field into electric energy, since we are always surrounded by ambient alternating current (AC) magnetic fields induced from electric power transmission lines everywhere. This article reviews the recent domestic research progress in high-performance MME generators and their application field for IoT and electronic devices.

Consumption value has widened, not only in functional but also aesthetic aspects, and consumers have started to find products that are more individual and emotional. The pattern of natural motifs meets the needs of consumers, and the marble is also widely used in patterns as one of the natural motifs. In this study, we analyzed many fashion items and other products with marble patterns based on the elements of CMF design, which are important points in merchandise design. For research, data on marble and its patterns have been found in professional books about marble. Foreign and domestic cases were investigated from well-known design exhibitions. Results of the study demonstrate the potential for pattern representation that stimulates consumers' senses by using color or material to express a variety of visual patterns, and using many finishing methods to express textured patterns. However, most of the domestic cases have only imitated the visual features of marble patterns, and very few have expanded the scope of the use of the patterns. A domestic research study was conducted only on the chemical features of marble, while research on the color and design of the visual aspects has been conducted passively. Therefore, This study will attribute designers to come up with creative pattern design and secure many consumers. Above all, we hope that the expansion of material representations will help designers break away from today's stereotypes of the characteristics of the materials and emotional expression.
