The paper analyzes GMO legal system and the problems of its management in China and their suggestions to Korea. GMO has been arising as a principal alternative of grain while grain prices continue to climb. Although there has been concerns about GMO imported from China, it is true that we have not studied on China's legal system and the problems of its management in China. The paper believes that when Chinese government does not manage GMO primarily, we have a high possibility that China's GMO food will access to Korean market at any time, and threaten our health and safety. Hence, it is highly time to analyze how legally China treats GMO and what the problems of its management are. The paper found out problems of China's GMO management in three ways. Firstly, GMO legal system of China is confused and it has limitation of effectiveness. China has no regulations like "a law" to regulate GMO and regulations which exists now are not easy to apply in substance. Secondly, China has no administrative strictness to manage GMO. For example, the regulation which ministry of agriculture in China promulgated in March of 2002 started to use partially since 2003, 7. Thirdly, China, as a nation that administration superiors to, market does not do its roll to control GMO. It relates to the low concerns and care of Chines people about GMO. The paper shows suggestions and countermeasures according to problems of China's GMO management.

Wernicke's encephalopathy is a fatal neurological disease caused by thiamine deficiency. Many reports indicate that Wernicke's encephalopathy is caused by malnutrition. We report the case of a 79-year-old female patient who had a left masticator space and parapharyngeal space abscess who was diagnosed with Wernicke's encephalopathy. She reported problems while eating due to the presence of the abscess, but the true quantities of food she was ingesting were never assessed. Clinicians have a responsibility to provide adequate nutritional support by ensuring that patients receive adequate nutrition. Clinicians should also keep in mind that Wernicke's encephalopathy may occur in patients who experienced prolonged periods of malnutrition.

In this paper, we present a symbiotic evolutionary algorithm for multi-objective optimization. The goal in multi-objective evolutionary algorithms (MOEAs) is to find a set of well-distributed solutions close to the true Pareto optimal solutions. Most of the existing MOEAs operate one population that consists of individuals representing the entire solution to the problem. The proposed algorithm has a two-leveled structure. The structure is intended to improve the capability of searching diverse and food solutions. At the lower level there exist several populations, each of which represents a partial solution to the entire problem, and at the upper level there is one population whose individuals represent the entire solutions to the problem. The parallel search with partial solutions at the lower level and the Integrated search with entire solutions at the upper level are carried out simultaneously. The performance of the proposed algorithm is compared with those of the existing algorithms in terms of convergence and diversity. The optimization problems with continuous variables and discrete variables are used as test-bed problems. The experimental results confirm the effectiveness of the proposed algorithm.

This study assessed the current EAR, RDA, and AMDR for protein, which were set in 2005 and revised in 2010 as the DRIs for Koreans. A classical approach to establish the EAR for protein has been the nitrogen balance method. This method has practical limitations and problems in statistical analysis by giving over estimations of nitrogen balance. Thus, the present EAR for protein might be lower than the true requirement. Recent reevaluations of nitrogen balance studies by bilinear regression analysis and the IAAO method have indicated that the EAR of 0.66 g/kg bw/d should be increased by 39% to give 0.92 g/kg bw/d. The AMDR for protein in the Korean DRIs was set at 7-10%, which covers almost the entire population's protein intake. Since the 5th percentile of Korean protein intake is close to 10% of energy and due to the beneficial effects of protein beyond the maintenance of nitrogen equilibrium, the lower range of 7% needs to be increased up to 10%. For practical meal arrangement, 15% of energy as protein, which is close to the average protein intake of Koreans, seems to be proper, although the value is almost two times the EAR.

The typical traction diverticulum of the mid-thoracic esophagus is conical or funnel shaped with a wide orifice, is small (rarely exceeding 2cm in length), and is situated horizontally or extends superiorly. It is a true diverticulum, having a complete investment by the esophageal muscle coats. Each of these characteristics promotes easy emptying of the diverticulum. Since food accumulation is presented, there is no tendency to progressive enlargement of the sac, and no associated dysphagia. The diverticula of mid-esophagus rarely develop and rarely produce symptoms. When symptoms develop, they are usually caused by granulomatous infections of the mediastinal lymph nodes. And also such diverticula only rarely give rise to significant complications, the most serious of which is a tracheobronchial fistula. Generally when such complications develop or a diverticulum itself produces symptoms, moderate or severe, surgery intervenes. A case of mid-esophageal diverticulum, traction type, which surgically treated with good results, was experienced at the Department of Thoracic Surgery of Kyung-Pook University. School of Medicine. In this case, there were substernal discomfort, acid regurgitation, and back pain for about 6 months. On the operative findings, it was noticed that the diverticulum was developed by traction and adhesion of perihilar nodes to the esophageal wall. The diverticulum was a small finger tip size and the neck of it was obscure. The surrounding inflammatory change was minimal.

Oysters are known to be carriers of food-born diseases, but research on viruses in Korean oysters is scarce despite its importance for public health. We therefore tested oysters cultivated in Goheung, Seosan, Chungmu, and Tongyeong, for viral contamination using cell culture and integrated cell culture PCR (ICC-PCR) with Buffalo green monkey kidney (BGMK) and human lung epithelial (A549) cells. Additional screens via PCR, amplifying viral nucleic acids extracted from oysters supplemented our analysis. Our methods found 23.6 %, 50.9 %, and 89.1 % of all oysters to be positive for adenoviruses when cell culture, ICC-PCR, and direct PCR, respectively, was used to conduct the screen. The same methodology identified enteroviruses in 5.45%, 30.9%, and 10.9% of all cases. Most of the detected enteroviruses (81.3%) were similar to poliovirus type 1; the remainder resembled coxsackievirus type A1. A homology search with the adenoviral sequences revealed similarities to adenovirus subgenera C (type 2, 5, and 6), D (type 44), and F (enteric type 40 and 41). Adenovirus-positive samples were more abundant in A549 cells (47.3%) than in BGMK cells (18.2 %), while the reverse was true for enteroviruses (21.8 % vs. 14.5 %). Our data demonstrate that Korean oysters are heavily contaminated with enteric viruses, which is readily detectable via ICC-PCR using a combination of A549 and BGMK cells.

The main purpose of this study is to examine the different physicochemical properties of spray-dried products. The carrier agents and powders after the spray-drying process were analyzed for encapsulation yield, moisture content, color parameters, total polyphenol content (TPC), antioxidant capacity (AC), bulk density, flowability, wettability, hygroscopicity, water solubility index (WSI), particle size and microstructure. The spray-drying process was carried out with different carrier agents including maltodextrin (MD) and the combination of maltodextrin and gum arabic (MD-GA) with MA/GA ratio of 70/30, dried at the inlet/outlet air temperature of 160 ℃/70 ℃, 4 bar, airflow rate of 70 ㎥·h^-1 and feed flow rate of 750 mL·h^-1. The results showed that the different carrier agents have significant influences on the physicochemical properties of the powder produced by the spray-drying method. In there, while the values of recovery efficiency and flowability of spray-dried products from MD are higher than those of spray-dried products from MD-GA combination, the opposite is true for the values of TPC, AC, bulk density and wettability, whereas hygroscopicity and WSI values are equally represented in both products.

There are several certification systems in agricultural products in Korea. Some examples are organic certificate, GAP certificate, KPGI certificate, Top Fruits/ Rice certificate and so on. The certification systems have been launched to guarantee the quality and safety of agricultural products to consumer. Despite the definite objectives of each certification system, it is said that the certification systems have not been successful to convey the related information to consumers. One of the reasons is that there exist several certificates so make consumers confused. It is also quite true that maintaining and promoting an individual certification system are highly costly from a point of institute's view. This paper proposes a plausible solution to these problems by combining several certificates.

It has often been said that Myanmar is the most profound Buddhist country in the world. That may well be true, but the brand of Buddhism practised in this isolated land is unique on the face of the globe. Myanmar Buddhism is theoretically Theravada Buddhism, a sect of Buddhism adhering most closely to the Buddha's teachings, and is the dominant form of Buddhism throughout Southeast Asia. The customary law also has an indissoluble connection with Buddhism in the Burmese society. The family customs and law have been put in statutory form with Damathat. And Damathat which is a statute law plays a important role as a mirror of the popular society. In Burmese society, the network which connects an individual and an individual fulfills its more function than the relatives and families act with group. The human relation which is generally completed within home, for example, parents and children, brothers and sisters, husband and wife and so on is situated as a center of the network which spreads outside home also in Burmese society. And Burmese society is 'khin' and 'ana' society. Burmese people positively extend the human relation through the way of thinking of Myanmar language 'khin' translated 'intimate', but they also put on the brakes the extending human relation without ending by keeping its distance through the way of thinking of Myanmar language 'ana' translated 'refuse courteously.'

Obtaining powder form of seaweed is essential for the use of seaweed as a food additive. The deterioration of seaweed caused by high temperatures during homogenization and powder processing is a serious problem and limits the use of seaweed as a food or pharmaceutical ingredient. Furthermore, many powder particles are not fluidized very well because of the interaction between particles. In order to solve this problem, sea tangle was hydrolyzed to a level of single cell detritus (SCD) by Vibrio sp., isolated from Batillus cornutus. with strong hydrolytic activity. The crude protein and amino acid contents of sea tangle SCD were higher than those of the powder, whereas the reverse was true for ash content. Sea tangle powder contained more mineral than its SCD, whereas total amino acid content was 5 times more in SCD than in power. The anticancer activities of sea tangle SCD and powder were 31.20 and 29.07%, respectively, with no significant difference (p<0.05), but about 15% higher than that of the control. The ACE inhibitory activity of the sea tangle powder, 39.31%, was higher than the 26.07% of the SCD. The antithrombin activity of the sea tangle powder, 55.3 seconds, was higher than the 34.5 seconds of the SCD. Moreover, there was no antioxidative and ischemic activities in both tile sea tangle powder and SCD.
