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.

The Miaos who is the minority people mainly living in the southwestern part of China, expressed their indicator and solidarity through the costume in order to maintain their racial character while experiencing numerous adversities over thousands of years, where the costume has served as a source of cohesion as well as a primitive religious thought, and also showed their faith, desire, longing and aspiration. This study examined the Miao's traditional costume by classifying it into the following; hair style, headdress, upper and lower garments, and other costume. And the silver ornaments used for attire and their symbolic meaning were examined. The result of the study is summarized as follows. 1. The reason that types of the costume has been diversified is because there was promise of ancestors who intended to differently express the type of a kind as symbol of the racial branch that is the Miao's special type of society. Thus, the costume type could tell where a tribe live. Another reason is because only marriage between families with different surname but the same type of costume was accepted. 2. As women made and wore the costume themselves, it also served as a means of being proud of their skill or wealth, they tried to make it more beautiful and it was also used as a token of marriage or love between relatively enlightened men and women. 3. The design used on the costume was expressed as a symbolic meaning of indicator to strengthen the racial solidarity because it connoted worship to ancestors who had experienced lots of adversities. 4. The hair style was expressed in various styles by using Kache such as Chukye, Byunbal and Kokye. It is likely that ornaments used on the head of women in the form of cow's horn or silver crown were used as one of the methods to stress the valuableness of the cattle that were essential to agricultural life. In addition, various styles of turbans were used to indicate the respective regions. 5. Cock's feather ornaments or silver ornaments in the form of pheasant's feather on the edge of women's skirts, peasant's feathers that men wore on their head, or Baekjoui and men wore resulted from the Miaos' thought of adoration for birds, which implied a primitive religious meaning. 6. As the region where the Miaos live yields much silver, the silver ornaments were mostly used to be proud of wealth, which symbolized light and pureness.

This paper investigates the long run hedging ability of precious metals against the risks associated with adverse conditions of economic and financial variables for Pakistan, the USA, China, and India. Monthly data of gold, silver, platinum, stock returns, exchange rate, industrial production, and inflation was collected for the selected economies. Saikkonen and Lutkepohl (2002) unit root test was employed to access the unit root properties of the data series and identify the break dates. Furthermore, this study used the Johansen cointegration test with and without structural breaks to identify the long-run relationship between metals prices and different financial and economic variables. The findings suggest that the time series under study have unit root problem at level with and without structural breaks. Without considering structural breaks, the Johansen trace test indicates that in Pakistan and China, gold, silver, and platinum hold a cointegrating relationship with macroeconomic and financial variables. For the US, gold indicates cointegration which supports the hedging ability of gold against inflation, stock, and industrial production in the long run. The results of the cointegration test after incorporating the structural breaks provide even stronger evidence of the long-run relationship of precious metals and consumer prices, exchange rate, and stock prices.

실리카 지지체 위에 은 (silver) 나노 입자를 부착시키는 방법으로는 지지체 표면을 먼저 은입자와 친화성이 큰 amino(-NH2), mercapto(-SH), cyan(-CN) 등의 관능기로 표면처리 하는 방법이 일반적으로 사용된다. 구체적으로 설명하면 첫 단계로 지지체인 실리카입자의 표면을 아민으로 표면 처리 한다. 실리카 입자위에 부착된 아민관능기는 입자 생성의 단계에서 은 (silver) 나노 입자가 붙는 접촉점의 역할과 핵 생성 장소로서의 역할을 하게되고, 아민 관능기의 이런 역할로 실리카 입자 표면에 부착된 핵이 생장하여 입자가 됨으로써 최종적으로 은(silver) 나노 입자가 실리카 지지체위에 부착된 형태의 나노복합체가 형성된다. 분자량이 다른 PVP를 사용하여 제조한, NH2와 SH로 계면처리 된 은-실리카 나노복합체제조를 시도하였다. 사용되는 PVP의 분자량이 증가함에 따라 긴 고분자 사슬에 의하여 생성된 입체장애가 증가하게 되어, 은 핵의 성장에 대한 물리적 장벽이 증가하게 된다. 그러므로 고정화된 은 입자의 크기가 감소하게 된다. 이러한 형상은 NH2기 또는 SH기로 계면 처리된 실리카를 이용하여 제조된 은-실리카 나노복합체 입자들에서 모두 관찰되지만, SH기로 계면처리된 실리카를 사용할 경우 고정화된 은 입자의 수가 더욱 많고, 크기 역시 더욱 균일함을 알 수 있다.
