Keeping in step with four seasons, Spring, summer, autumn, and winter, the heaven and earth(天地) has been born(生), grown(長), coverted(化), gained(收), and kept(藏) by interaction of yiyang and yuqi(五氣: 木火土金水). And according to Naiching, human being is born with energy of heaven and earth(天地之氣) and is grown with the law of four seasons(四時之法). So, we now know that the human's body and nature interact each other. The oriental medical science has been studied the effect that the nature's change influences on human body. Now, I get some idea that using herb medicine and acupuncture should have hanged following the change of four seasons. We know that there is a cycle in nature. Every day sun arise and down, and every month moon gets full and new. And every year, four seasons orderly change, from spring to winter. All of this is the law of nature and human body adapts this law. Man always shows the physiological phenomena which changes under the law of nature, especially the turning of the seasons. Therefore, we should use different medical methods in different seasons.

Recently, a large number of people are growing interested in Korean cuisine and progress Korean culture. This study inverstigated several kinds of Korean traditional alcoholic drinks and brewing methods, including ingredients in ancient culinary manuscripts "Soowoonjabbang", "Eumsikdimibang", "Onjubub", "Jusiksiui", "Uumjeabang" and "Eumsikbangmunnira" of Korean head family. Korean traditional alcoholic drinks were sorted into two groups based on characteristic (danyang ju, yiyang ju, samyang ju, sayang ju, yakyoung ju, gahyang ju, honyang juand soju) and five categories based on preconditioning methods of Korean traditional alcoholic drinks (iporrige, baeksul ki, gumung tteok, godubap, bumbuck). The most announced ancient Korean culinary manuscript is "Onjubub" (57 varieties of Korean traditional alcoholic drinks), the second largest book is "Eumsikdimibang" (49 varieties of Korean traditional alcoholic drinks), and the third highest book is "Soowoonjabbang" (40 varieties of Korean traditional alcoholic drinks). The "Uumjeabang" and "Eumsikbangmunnira" announced 21 and 15 varieties of Korean traditional alcoholic drinks in six books of ancient Korean culinary manuscripts, respectively.

In this paper, we investigate an interference mitigation scheme by antenna selection in device-to-device (D2D) communication underlaying downlink cellular networks. We first present the closed-form expression of the system achievable rate and its asymptotic behaviors at high signal-to-noise ratio (SNR) and the large antenna number scenarios. It is shown that the high SNR approximation increases with more antennas and higher ratio between the transmit SNR at the base station (BS) and the D2D transmitter. In addition, a tight approximation is derived for the rate and we reveal two thresholds for both the distance of the D2D link and the transmit SNR at the BS above which the underlaid D2D communication will degrade the system rate. We then particularize on the small cell setting where all users are closely located. In the small cell scenario, we show that the relationship between the distance of the D2D transmitting link and that of the D2D interfering link to the cellular user determines whether the D2D communication can enhance the system achievable rate. Numerical results are provided to verify these results.

Mobile social network is becoming more and more popular with respect to the development and popularity of mobile devices and interpersonal sociality. As the amount of social data increases in a great deal and cloud computing techniques become developed, the architecture of mobile social network is evolved into cloud-based that mobile clients send data to the cloud and make data accessible from clients. The data in the cloud should be stored in a secure fashion to protect user privacy and restrict data sharing defined by users. Ciphertext-policy attribute-based encryption (CP-ABE) is currently considered to be a promising security solution for cloud-based mobile social network to encrypt the sensitive data. However, its ciphertext size and decryption time grow linearly with the attribute numbers in the access structure. In order to reduce the computing overhead held by the mobile devices, in this paper we propose a new Outsourcing decryption and Match-then-decrypt CP-ABE algorithm (OM-CP-ABE) which firstly outsources the computation-intensive bilinear pairing operations to a proxy, and secondly performs the decryption test on the attributes set matching access policy in ciphertexts. The experimental performance assessments show the security strength and efficiency of the proposed solution in terms of computation, communication, and storage. Also, our construction is proven to be replayable choosen-ciphertext attacks (RCCA) secure based on the decisional bilinear Diffie-Hellman (DBDH) assumption in the standard model.

Exotic conifer trees have been extensively planted in southern China because of their high apparent growth and yield. These fast-growing plantations are expected to persist as a considerable potential for temporary and long-term carbon sink to offset greenhouse gas emissions. However, information on the carbon storage across different age ranges in exotic pine plantations is often lacking. We first estimated the ecosystem carbon storage across different age ranges of exotic pine plantations in China by quantifying above- and below-ground ecosystem carbon pools. The carbon storage of each tree component of exotic pine (Pinus elliottii) increased significantly with increasing age in Duchang and Yiyang areas. The stem carbon storage except <10 years in Ji'an areas was the largest component among all other components, which accounts for about 50% of the total carbon storage followed by roots (~28%), branches (~18%), and foliage (~9%). The mean total tree carbon storage of slash pine plantations for <10, 10-20 and 20-30 years across three study areas was 3.69, 13.91 and $20.57Mg\;ha^{-1}$, respectively. The carbon stocks in understory and forest floor were age-independent. Total tree and soil were two dominant carbon pools in slash pine plantations at all age sequences. The carbon contribution of aboveground ecosystem increased with increasing age, while that of belowground ecosystem declined. The mean total ecosystem carbon storage of slash pine plantations for <10, 10-20 and 20-30 years across China was 30.26, 98.66 and $98.89Mg\;ha^{-1}$, respectively. Although subtropical climate in China was suitable for slash pine growth, the mean total carbon stocks in slash pine plantations at all age sequences from China were lower than that values reported in American slash pine plantations.

Jie Jie Hao Yin 『절절호음(節節好音)』 is a script collection produced during the Qianlong's ruling Period which had one of the most flourished period of Qing Dynasty's Palace Drama. This script collection is consisted of 86 scripts of 6 Festival Court Plays: New year's day (元旦), Lantern festival(上元), Yanjiu festival(燕九), Snow appreciation(賞雪), Day of Kitchen god worshipping(祀竈), New year's eve(除夕). These scripts are effective records to study the New Year's Eve Drama of Qianlong Period. Jie Jie Hao Yin carry out the performances not only through Kunqiang (崑腔), and Yiyang Tune (弋腔), but also through various types of entertaining performances such as dance, masque play, puppet show, and story telling. Most of the songs were sung by various gods praising the era of peace as the holiday approaches. In the contents of revealing the luck to be brought by the holidays, it sought for the colorful transformations of stages through adding humoristique short stories or various feast genres in between the performance. It also tries to seek for diversities of stages through active application of acrobatics. It also portrays folk customs from BaiYunGuan's temple fair, Yanjiu Festival in YanBin, the Lantern Fair of Lantern Festival, and various activities of wet markets from New Year's Eve from diverse points of views. Especially through various shows and Chinese folk-art forms, the popular folk activities and entertainments near Beijing in the beginning era of Qing Dynasty can be observed. Jie Jie Hao Yin is a very important resource to look at the popular art activities of Beijing during Qianlong Period, and how the Palace culture accepted the folk cultures and applied to its own advancements.
