Goat milk production and processing is a dynamic and growing industry that is fundamental to the health of hundreds of millions of people worldwide and is recognized as an important contributor to many national economies. Goat milk has contributed significantly to the economic and nutritional quality of life in developing countries, particularly in the Mediterranean, the Middle East, Eastern Europe, and Latin America. Goat milk has played an important role in the health and nutrition of infants and the elderly, and is also known to be beneficial and therapeutic for people with milk allergies. The potential and value of the nutritional, health, and therapeutic effects of goat milk and specialized goat milk products are now attracting attention. Various products can be made from goat milk based on its chemical properties. In addition, special products such as hair, skin care, products, and cosmetics produced using goat milk have garnered more attention in recent years. Nevertheless, high quality products can only be made from good quality goat milk. Advanced technical treatments are necessary to produce high quality goat milk that meets consumer expectation of nutritional, hygienic, and good sensory products. Good taste has been a critical criterion when deciding to buy and consume goat milk and associated products. However, it may be possible to produce more value-added products that cater to the new trends in consumer needs and thus maintain economic sustainability of goat milk industry.

One of the most considerate phenomena of the era of the Fourth Industrial Revolution is the use of digital devices. Digitalization is rapidly advancing through all areas of industry and life. Customer journey with digitalization is looking totally different from previous customer journey. The research targets were users of fashion, automobiles, cosmetics and online shopping malls. We analyzed 300 people for each valid questionnaire. The results of the study are as follows. First, it has been proven that digital experience affects positive (+) impact on purchasing intention and positive (+) impact on recommending intention and negative impact (-) on switching intent and subsequently affects positive impact (+) to purchase and incase of switching intent, negative impact (-) to purchase. Unlike traditional methods such as SPC(Service Profit Chain), the Digital experience to Purchase process Chain (DPC) has been identified to be suitable in the digital age. Second, the digital satisfied group (5 score-very satisfaction) has shown same result as above. However the digital neutral group (even though 4 score- satisfaction in five-point scale), specially in a highly competitive industry, has different from the satisfied group and 3 score-normal is same as dissatisfied group. It means that this group is that If there is a high level of attractiveness of substitute goods, there is a high possibility of switching them. It has supported Jones and Sasser [1995] that there have been two types of loyalty of true long-term loyalty and what we call false loyalty in the highly competitive industry zone which is commoditization or low differentiation, many substitutes, low cost of switching. Identifying true loyalty and false loyalty is crucial to establishing a customer experience strategy. it is necessary to actively utilize long-term digital experiences strategy to increase the total satisfaction of digital experience through all of customer purchasing journey in order to enhance the digital customer experience. It is difficult to see the effect as a one-time event. It should be scaled over the entire customer purchase process over a long period of time, which can positively affect purchase intention, recommendation intention, and conversion intention. This is also why it is difficult for second-runners to overtake first-runners in a short period.

이 연구에 사용된 9종류의 나노입자는 직경 100nm 이하의 크기를 가진 입자로, 알테미아 cyst가 nauplius로 부화되는 과정에서 어떠한 영향을 미치는지 살펴보았다. 24시간 경과 후 나노입자를 첨가하지 않은 대조구에서는 82%가 nauplius의 부화하였다. 20mg/L 농도에서는 AGZ020, Nano silver, P-25, Sb, 및 SnO 나노입자가 각각 18%, 20%, 13%, 50% 및 0%의 부화율을 보여 유해성이 큰 것으로 나타났으나, Ag-$TiO_2$, In, Sn, 및 Zn 나노입자에서는 각각 75%, 60%, 73% 및 73%로 대조구에 비해 유해성을 가졌지만, AGZ020, Nano silver, P-25, Sb, 및 SnO 나노입자에 비해 상대적으로 미약한 것으로 나타났다. 이는 나노입자가 가지고 있는 성분에 따라서 차이가 났다. AGZ020, Nano silver 및 P-25 나노입자는 은(Ag)이 2% 함유되어 항균제로서 널리 사용되어지고 있으며, 산소를 결합시킨 SnO 나노입자는 광촉매제로 사용되고 있다. 이들 나노입자들은 현재 가전, 기능성 화장품, 항균제 및 광촉매제 등 사용이 일반화되어 수중환경으로 유입될 가능성이 높아지고 있다. 이에 따라 수중생태계에 전파 영향을 준 가능성이 높기에, 나노입자가 가지는 잠재적 위험성을 지속적으로 연구해야 할 것이다.

In this paper, we present the improvement in low moisturizing ability and stability that existing skin softeners have due to the low oil content, by developing skin softener using nanoemulsion of phospholipid liposome, based on the properties of nanoemulsion in cosmetic formulation. In this study, two types of oil; dimethicone (DC 200/6cs) or medium chain triglyceride (MCT), and two kinds of lecithin; unsaturated or saturated were respectively applied to produce nanoemulsion. In the particle size analysis of nanoemulsion, the droplet size of nanoemulsion containing DC200/6cs and unsaturated lecithin was the smallest, and all nanoemulsion showed high stability in the measurement of zeta potential. Therefore, with the smallest particle size and high stability, moisture contents and trans epidermal water loss(TEWL) were measured using the skin softener of DC200/6cs and unsaturated lecithin contained nanoemulsion, and the measurement was compared with the non-oil skin softener and the skin softener with only small amount of oil. The results showed that the moisture content of the skin softener using nanoemulsion increased greatly than other two skin softeners, showing high hydration ability and water retention capacity, and TEWL decreased greatly, therefore preventing the evaporation of moisture from the skin. As a result, the oil content and stability of the skin softener was improved by utilizing nanoemulson based of phospholipid liposome, and it is expected to be used in various ways in cosmetic industry.

Deep sea water exists at depths of over 200m under the sea. As no sunlight reaches it, photosynthesis does not take place within it, and it contains no organic matter. In addition, its temperature is maintained at a stable low level throughout the year, so it does not get mixed with the sea water on the surface. It contains a large amount of nutritious salts, whose cleanness is maintained. It is a marine resource that has matured for a long period of time. Research into deep sea water, which started in the 1970s, has been made around the whole world, including the USA and Japan. In Korea, research has been active in this area since 2000. As there has been a good amount of research into industrial applications for deep sea water, since 1993, patents for the relevant technologies have been applied. This paper intends to provide a resource to researchers of deep sea water, by summarizing of all domestic deep sea water-related patents applied with Korean Intellectual Property Office from 1993 to 2008. This research was conducted using a computer and KIPRIS Database owned by the Korea Institute of Patent Information. 'Deep sea water' was used as the search keyword. A total of 222 Korean patents relating to deep sea water have been registered on the basis of IPC. Of these, 126 patents relate to the manufacturing and the treatment of foods, foodstuffs, or non-alcoholic beverages(A23L), while 50 patents relate to the production for medical, dental, or cosmetic purposes(A61K). 38 patents relate to water purification, treatment of wastewater, sewage and sludge (C02F), while 8 patents relate to fishery and farming(A01K). In summary, it was found that studies for the practical use of deep sea water have been conducted in relation to the manufacturing and the treatment of foods, foodstuffs, beverages, and cosmetics.
