        The endothelium, a continuous monolayer of cells that surrounds blood vessels, has a variety of physiological roles. Chronic exposure to psychological and physical stress, oxidative stress, and inflammation activates the endothelial signaling cascade, resulting in vascular dysfunction such as vasospasm, thrombosis, and abnormal vascular proliferation. Aging is also a significant factor in vascular dysfunction, mainly developing structural and functional changes in the endothelium. The molecules involved in endothelial dysfunction are typically angiopoietin-1 (Ang-1), Tie2, and tight junction proteins. Ang-1, an oligomeric-secreted glycoprotein, is required for the correct organization and maturation of newly-formed vessels. Ang-1 binding to tyrosine kinase receptors Tie-2 leads to the phosphorylation and activation of multiple signaling pathways related to vascular permeability. Endothelial junctions are another vital target of Tie-2 activation. Nutrition and food are closely connected with vascular dysfunction and permeability. The caloric restriction prevents age-related declines in endothelial function. Dietary patterns that prioritize moderate intake of fruits and vegetables, whole grains, low-fat dairy products, and lean meats improve endothelial function in the elderly. Natural products such as Centella asiatica, Pueraria montana, and Piper retrofractum have also been shown to help inhibit endothelial dysfunction. This review provides an update on aging-related vascular dysfunction and the role of food and nutrition.

        The aim of this study was to forecast the future Health Functional Food (HFF) market trends of Korea by studied about policies and market situation in Japan. The HFF is a food that is given an additional health function. In contrast with traditional foods, the HFF has unique characteristics in that it can be produced under the political regulations. The market size of the HFF was growing gradually due to the increased of an aging population and consumer need for high quality and diversified foods. The reason why the HFF market in Japan grew up earlier than other countries, Japan was the first country that institutionalized the HFF policies. Therefore, in this paper, by examining the policies and the market situation of Japan through literatures, we forecasted upcoming political and market situational changes of Korea’s HFF market. We noticed that consumers needs about the HFFs which diversified, confidently ensured safety and ingredients will increase. In this regard, the government will reorganize legislation in order to increase the confidence of the safety of HFFs. In addition, the market size of domestic HFFs which are produced by major food companies will grow.

        This study was conducted to assess the recognition and consumption of health functional food (HFF) of the college students in the Northern Gyeonggi-do area (Republic of Korea). To accomplish this, a survey was conducted to investigate 360 college students (183 males and 177 females) regarding their general characteristics, as well as the recognition, knowledge, considerations, purchases and consumption of HFF. Most male and female students (68.9% and 61.6%, respectively) were unaware of the HFF certification mark, however, more females(58.8%) were aware of the legal HFF definition compared to males (36.6%). The HFF advertising routes for males and females were ‘TV radio’ (43.2% and 43.5%, respectively) and ‘internet smart phones’ (19.7% and 27.1%, respectively). The main factor considered for selection and the most serious problem concerning HFF by males and females were ‘effectiveness’ (36.1% and 43.6%, respectively) and ‘hype (exaggerated advertisement)’ (35.0% and 55.9%, respectively). The main purchase route by males and females was ‘pharmacy’ (35.2% and 27.8%, respectively). The main reason for HFF product purchase by males and females was ‘health promotion’ (38.8% and 29.4%, respectively) and the main reason for not purchasing an HFF product was ‘no health problem’(34.8% and 36.7%, respectively). The percentage of HFF consumption was 46.0% in males and 69.8% in females. The main HFF product consumed by males and females was ‘vitamin mineral’ (36.9% and 43.5%, respectively). The main reason for HFF consumption by males was ‘health promotion’ (31.0%) and females was ‘recovery from fatigue’ (21.8%). The main reason for not consuming HFF by males and females was ‘no health problem’ (38.4% and 41.5%, respectively). These results suggest the need to provide correct information concerning HFF to college students. Based on these results, greater efforts should be made to provide meaningful information regarding factors affecting purchase and consumption patterns for college students related to the research and development of HFF in the Northern Gyeonggi-do area.

        The purpose of this study was to investigate factors influencing sales of health functional foods by door-to-door saleswomen. A total of 450 women who worked as door-to-door salespersons in Seoul were enrolled. The survey questionnaire was composed of five parts as follows: general characteristics, factors related with door-to-door sales process, task education, competency required for door-to-door salespersons, and customer relationship beliefs. The survey was conducted in October 2011. Finally, data on 302 subjects were statistically analyzed using the SPSS 17.0 package program. Reason for sales of health functional foods (p<0.01), time required for sales promotion (p<0.001), difficulties during sales of health functional foods (p<0.05), satisfaction of task education (p<0.01), and failure of salesperson's memory as problems of task education (p<0.01) were significantly associated with sales of health functional foods. However, means of sales promotion, frequency and time of task education, and competency required for door-to-door salespersons were not significantly related with sales of health functional foods. Customer relationship beliefs did not show significant association with sales of health functional foods either. In conclusion, certain factors were associated with sales of health functional foods by door-to-door saleswomen. These results provide an understanding for sales of door-to-door health functional foods and provide basic information for preparation of task education for health functional food saleswomen and marketing.

        Proper skin care promotes good metabolism and the biological activity of skin, helps maintain the skin in a healthy and beautiful state when combined with nutritional nourishment. Health functional foods are being used for the purpose of enhancing efficient skin care. Health functional foods related to skin care maintain the epidermis, dermal fibroblast layer and subcutaneous tissue that form the skin. Efficient functional foods alleviate the signs of endogenous aging that come with getting older and exogenous aging caused by sunlight. Even though the field of skin care related to health functional foods has received less attention and been the subject of less research compared to functional cosmetics which are developing widely, this area of skin care that maintains and improves the layer of dermal fibroblast through the intake of food, is expected to progress with the commercialization of products in many fields when the related technical research development is galvanized and the related patents are applied for. Research into health functional foods related to skin care in Korea started rather late in comparison to other advanced countries where patents for relevant techniques have been applied for since 1990's together with research conducted on how they might be used for practical purposes. This study used the key words ‘skin care, health functional food’ to search for Korean patents that have been applied for at the Korean Intellectual Property Office from 1983 to 2011 using the KIPRIS database, in order to help researchers in the related fields by organizing the patented formulas for health functional foods for skin care which have gained attention recently. According to the number of registrations in each industry field, the total number of patents was 1, 120 we screened the major patents among them, the field with the largest number was food foodstuff non-alcoholic beverage and preparation or treatment(A23L) with 135, then natural plant medicine & medical supplies and cosmetics(A61K) with 112, microorganisms or enzymes(C12N) with 63, heterocyclic compounds(C07D) with 44, horticulture or cultivation of sea weeds, forestry(A01G) 16 times, listed from the highest to the lowest number of applications. It has been revealed that food, foodstuff, non-alcoholic beverage and preparation or treatment(A23L) was the industry field where the most patents for health functional foods related to skin care were registered.

        This study developed learning content and web pages providing information on Health/Functional Food (HFF) for consumers who come across information indiscriminately from a variety of advertising media such as the Internet and TV. After coming to an understanding of the current situation through literature review and fact-finding, we collected information and commercials on HFF that are exposed to consumers. Focusing on advanced countries such as the U.S. and Japan, we examined the current status of consumer education programs, especially in terms of HFF industry. Further, we referred to the guidelines for consumer education provided by the U.S. Food and Drug Administration and monitored the information from a web site that sells dietary supplementary products in the U.S. In addition, we surveyed consumer information on foods for special health use provided by the Japanese National Institute of Health & Nutrition, and investigated a DB of raw materials of function food (functionality/safety documents). Upon a literature review, the 13 functions of HFF were classified. As a result of conducting interviews with consumers, we developed content that was fit for consumers’ perspectives. Through this research, we established a web page to enable people to search for information by function and then by raw material. After searching for information by raw materials, searching products by raw materials can be done in cooperation with E-marketplace. Subsequently developed content and education programs were offered on an HFF web page, which has been in operation since 2005. Therefore, it is expected that appropriate information on HFF will be available.

        포스트바이오틱스(postbiotics)는 프로바이오틱스(probiotics)가 발효과정 중 생산하는 유용한 대사산물과 미생물의 구성성분을 포 함하는 개념이다. 포스트바이오틱스는 기존 프로바이오틱스 소재가 갖는 안전성(safety), 기능성(function), 안정성(stability)의 한계를 극복할 수 있는 새로운 대안 소재로 주목받고 있다. 사균화 처리과정으로, 특정 대사물질의 복합물 형태로 제조되고 있기에 기존 생균제보다 가공, 포장, 유통, 섭취가 용이하다. 면역력이 낮은 환자나 건강 취약 계층의 소비자들도 안전하게 섭취할 수 있는 것도 장점이다. 뿐만 아니라, 체내에서 면역 조절, 감염 방지, 지질 및 콜레스테롤 대사, 항산화 기능을 보이고 있어, 앞으로 건강기능 식품 우수 소재로 활용될 가능성은 더 커질 것이다. 다만, 대부분의 연구들이 아직은 세포실험과 동물시험인 단계이기에 실제 인체적용 시험을 마친 소재들은 적은 편이다. 향후 꾸준한 연구성과를 바탕으로 다양한 기능을 가진 포스트바이오틱스 소재와 제품들이 개발된다면 건강기능식품 산업에 새로운 성장동력이 될 것으로 예상 된다.
