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.

『절절호음(節節好音)』은 청나라 궁정 연극이 가장 흥성했던 건륭(乾隆) 연간 내부(內府)에서 편찬한 월령승응희(月令承應戱) 극본집이다. 그 속에 원단(元旦), 상원(上元), 연력(燕九), 상설(賞雪), 사조(祀竈), 제석(除夕) 총 6개 명절의 86개 절희(節戱) 작품이 수록되어 있는데, 이를 통해 건륭 연간 송구영신(送舊迎新) 연극의 면모를 살펴볼 수 있다. 특히, 절절호음에서는 단지 곤강(崑腔)과 익강(弋腔)으로만 희곡 공연을 이어가는 것이 아니라 중간에 다양한 가무, 가면극, 인형극, 강창 공연들이 첨가되어 화려한 볼거리를 제공하고 있다. 주로 각종 신선들이 등장하여 명절을 맞아 천하가 태평함을 노래하고 명절의 상서로움을 드러내는 내용 속에, 삽연(揷演)의 방법으로 해학적인 내용의 짤막한 이야기나 다양한 연희 장르를 적극 활용하여 다채로운 무대 변화를 꾀하고 있다. 또 당시 연경(燕京)(오늘날의 북경(北京)) 지역 연구절 백운관(白雲觀)의 묘회(廟會), 상원절의 등시(燈市), 제석의 가시(街市)(요시(鬧市))에서 펼쳐지는 다양한 민속 활동의 모습을 다각도로 묘사하고 있다. 특히 그 속에 등장하는 다양한 백희(百戲) 자료들을 통해 청 초 북경을 중심으로 유행한 다양한 민간 연희 종목의 공연 양상을 엿볼 수 있다. 이를 통해 건륭 연간 북경 일대에 유행한 연희 종목 및 청 궁정에서 민간의 연희를 적극 수용하고, 발전·활용한 사례를 확인할 수 있어 매우 유용한 자료이다.
