Nowadays, economy diversity has developed dramatically. A new health concept has been transformedinto different fields----from appliance industry, sports industry to healthcare market. In appliance industry, there are healthy television, healthy refrigerator and so on. In sports industry, fitness and gymnasium are heating now. In healthcare market, the specific physical checkup center appeared. Health economy is a special branch of applied economics; it mainly deals with the demand and supply of products and services, aiming at bringing people healthy ways to live. This paper analyzes the reasons that health economy appeared in such a resourceful world and lists how to get a better energy saving method in different fields. © Sila Science. All Rights Reserved.

A dual-feed small-size penta-band PIFA for LTE/WWAN mobile handset applications is presented. The proposed PIFA is composed of a simple U-shaped patch with dual-shorting pins connected to the ground plane. The patch, having a low profile of 5 mm, has dimensions of about 10 × 35 mm2. The antenna is excited at one arm of the U-shaped radiating patch to cover the higher band of GSM1800/1900/UMTS2100/LTE2300/2500, while it is excited at the other arm to realize the GSM900. In this way, the proposed PIFA achieves enhanced bandwidth coverage with no increased dimensions and additional active switches. In addition, the matching networks, employed on both feeds, ensure a high electrical insulation between the low and the high frequency bands, covered by the antenna. The measured antenna efficiency is 45%50% and over 60% for the lower band and the higher band, respectively. A prototype of the proposed PIFA with dual-feed and dual-shorting pins was fabricated. The measured results including reflection coefficients and radiation characteristics are presented. © 2014 Mingyang Liu and Bin Zhao. Source

In recent years, with the rapid development of the World Wide Web, huge amount of data arises in our daily life. Which approach should be taken to assist users when searching the information they need is the point. For users, when facing the same resources, they more commonly annotate them or input search queries according to their own perspectives. This process has been already proven as a time-consuming. Based on the goal, we propose our methodology that to combine user's context, users' profile with users' Folksonomies together to optimize personal search. And at the end of this paper, we make an experiment to evaluate our methodology and which performs better. © 2015 IEEE. Source

In recent years there are some food incidents happened in China, especially in meat product industry, which caused great panic among people. This study lists some of the cases and analyzes the influence from different angles. It illustrates how to supervise processing and producing meat products under the technology of Internet of things, like sensor, RFID and trackers etc. The purpose is to offer a safe food environment in China and lead enterprises to set up a sound operation system to gain long-term profits as well. © Maxwell Scientific Organization, 2015.

Food security has become a big issue in China for some big incidents occurred in recent years. happened. This study has a survey on these cases and analyzes the reasons from the aspect of enterprises and government. Some solutions are put forward to solve the problems about food security and business credit crisis in China currently. The purpose is to guide enterprises to set up a sound operation system and gain long-term profits. © Maxwell Scientific Organization, 2015. Source
