During the past decade after entering the World Trade Organization (WTO), China has quickened its integration into the global economy while its foreign trade has been further invigorated. On the 10th anniversary of China's accession to the WTO, the Chinese government issues White Paper to give a comprehensive introduction to China's foreign trade development. Through this paper, the Chinese government introduces I. Historic Progress in China's Foreign Trade II. Reform of and Improvements to China's Foreign Trade System III. The Development of China's Foreign Trade Contributes to the World Economy IV. Promoting Basically Balanced Growth of Foreign Trade V. Constructing All-round Economic and Trade Partnerships with Mutually Beneficial Cooperation VI. Realizing Sustainable Development of Foreign Trade. At present, the underlying impact of the international financial crisis, the protracted, arduous and complicated nature of the world economic recovery is manifesting itself, and the global economic structure and trade layout face in-depth readjustment. China will make new adjustments to its foreign trade, in an effort to turn foreign trade from scale expansion to quality and profit improvement, and from mainly relying on its low-cost advantage to enhancing its comprehensive competitive edge, thereby turning China from a big trading country to a strong trading power. China's foreign trade is still hampered by many uncertainties and is bound to meet new difficulties and challenges. During the 12th Five-year Plan period China will open itself wider to the outside world as a driver for further reform, development and innovation, make full use of its advantages, strengthen international cooperation in all respects. And at the same time China integrate itself into the world economy on a wider scale and at a higher level. China is willing to work with its trading partners to cope with the various challenges facing the world economy and trade, and promote its foreign trade to realize a more balanced, coordinated and sustainable development, and share prosperity and mutually beneficial results with its trading partners.

The posterior hypothalamus of the hibernating greater horseshoe bats (Rhinolophus ferrumequinum korai Kuroda) were observed with an electron microscope. The posterior hypothalamus is known to be closely related to the reflex responses activated by cold, and the following observations were obtained in the cellular type of nerve cells: there are three types of neurons in the posterior hypothalamus. 1. The first type of neuron was the largest, ovoid or conical in shape, the nucleus was elliptic and the nuclear envelope had many deep invaginations. The cell organelles were well developed, in particular there was an abundance of variously shaped mitochondria, and the Golgi complex and the polysomes were observed in the cytoplasm. 2. The second type of neuron was moderate in size, ovoid or elliptic in shape, the nucleus was located nearer to the plasma membrane and the nuclear envelope had. a few invaginations. The cytoplasm was rich in amount compared with that of the third type of neuron, and the cell organelles, especially the rough endoplasmic reticulum were well developed. Also lipofuscin pigments were observed. 3. The third type of neuron was the smallest in size and round in shape. The nucleus and the nucleolus were observed in the central portion of the cell body and the nuclear envelope had a few invaginations. The cytoplasm was small compared with those of the first and second types, but the rough endoplasmic reticulum, the mitechondria and the polysomes were relatively well developed. The cytoplasm was characterized by the presence of membrane-bound small bodies with a single membrane containing a fine particular substance around the rough endoplasmic reticulum and the Golgi complexes.

Objectives: The aim of this study was to establish a clear diagnostic definition of Sanhupung using the Delphi method. Methods: This study used the Delphi technique. A panel consisting of 21 experts of Korean medicine, particularly in of gynecologic medicine, participated in the Delphi examination that included answering the 4th round survey. The Delphi examination was carried out through evaluating and correcting the questionnaire by e-mail. Results: Through the Delphi survey, we have reached on an agreement regarding the basic concepts, time, cause, essential symptoms, and accessory symptoms of Sanhupung. They are as follows: 1) Sanhupung is a culture bound syndrome reflecting Korea's cultural specificity. 2) Sanhupung can be diagnosed even after the miscarriage. 3) For the diagnosis of Sanhupung, the main cause of symptoms should not be classified as other disease. 4) Sanhupung can be diagnosed based on essential symptoms and accessory symptoms. 5) Essential symptoms include local symptoms such as joint pain at specific areas, partial sensory impairment and general symptoms including pain of all the joints, whole body sensory impairment, increased sweating, feeling of wind coming into the body, worsened symptoms with the cold, intolerance to cold, and pain of all the muscles. Conclusions: The basic concepts and diagnostic definition of Sanhupung were suggested based on the Delphi survey among experts in the field. Further research is necessary to improve reliability and validity of diagnostic definition of Sanhupung in clinical trials.

A novel glucanhydrolase from a mutant of Lipomyces starkeyi KSM 22 has additional amylase activity besides mutanolytic activity and has been suggested as promising anti-plaque agent. It has been shown effective in hydrolysis of mutan, reduction of mutan formation by Streptococcus mutans and removal pre-formed sucrose-dependent adherent microbial film and has been strongly bound to hydroxyapatitie. These in vitro properties of Lipomyces starkeyi KSM 22 glucanhydrolase are desirable for its application as a dental plaque control agent. In human experimental gingivitis　model and 6 month clinical trial, mouthrinsing with Lipomyces　starkeyi KSM 22 dextranase was comparable to 0.12% chlorhexidine mouthwash in inhibition of plaque accumulation and gingival inflammation and local side effect was negligible. This study was aimed to evaluate the cytotoxic effect of Lipomyces starkeyi KSM 22 glucanhydrolase on human gingival fibroblasts. Primary culture of human gingival fibroblasts at the 4th to 6th passages were used. Glucanhydrolase solution was made from lyophilized glucanhydrolase powder from a mutant of Lipomyces stakeyi KSM 22 solved in PBS and added to DMEM medium to the final concentration of 0.5, 1, and 2 unit. Cells were exposed to glucanhydrolase solution or 0.1 % chlorhexidine and the cells cultured in DMEM with 10% FBS and 1% antibiotics as control. After exposure, the morphological change, cell attachment, and cell activity by MTT assay were evaluated in 0.5, 1.5, 3, 6, 24 hours after treatment. The cell proliferation and cell activity was also evaluated at 2 and 7 days after 1 minute exposure, twice a day. The cell morphology was similar between the Lipomyces smkeyi KSM 22 glucanhydrolase groups and control group during the incubation periods, while most fibroblasts remained as round cell regardless of incubation time in the chlorhexidine group. The numbers of the attached cells in the glucanhydrolase groups were comparable to that of control and significantly higher than the chlorhexidine group. The numbers of the proliferated cells in the glucanhydrolase groups at 7 days of incubation were comparable to the control group and higher than the chlorhexidine group. The cell activity in glucanhydrolase groups paralleled with the increased cell number by attachment and proliferation. According to these results, Lipomyces starkeyj KSM 22 glucanhydrolase has little harmful effect on attachment and proliferation of human gingival fibroblasts, in contrast to 0.1% chlorhexidine which was cytotoxic to human gingival fibroblasts. Therefore this glucanhydrolase preparation is considered as a safe and promising agent for new mouthwash formula in the near future.

Kim Chan-sam's 『世界一周無錢旅行記』 was released in 1962. This was a time when the general public was strongly restricted from traveling abroad. Most of the people lived in 'domestic'. Low development and political upheaval continued. The readership wanted a fantasy, which came out of a desire to escape from the peninsula. So was to become more popular around the popular characters called 'Kim Chan-sam'. Kim Chan-sam had to be a pushover to the public. This figure had to be secular and de-politicized. Above all, ideological bias had to be removed. The book's imaginary geography is the "world as a non-communist state" with a high purity. The Cold War ideology was prevalent throughout South Korean society. Kim Chan-sam knew exactly what he could and could not tell the South Korean reader. He couldn't tell you the reality of my readers not being able to travel abroad. Not to mention a society locked up 'domestic' on the Korean reality. The study analyzes Kim Chan-sam's storytelling strategy. Looking at the meaning of the travel fantasy,agenre of the 1960s, I would like to ask why travel writing in our time is still bound by its past limitations.
