Nitrite plays an important role in the formation of carcinogenic nitrosamine. In order to effectively inhibit the formation of carcinogenic nitrosamine in food and biological systems, scavenging of residual nitrite is necessary. In screening test of nitrite-scavenging effect of seaweed, The methanol extract from Phaeophyta was more effective than those from Rhodophyta and Chlorophyta. Among the brown algae family, Laminariaceae, A. cribrosum (90.4$\%$) and E. cava (80.1$\%$), E. stolonifera (79.0$\%$) that belong to genus Ecklonia showed marked nitrite-scavenging effect at pH 1.2. Furthermore, these algae showed potent reducing power and radical scavenging activity. The nitrite-scavenging effect was correlated with level of reducing power.

Agricultural extension services in Korea are faced with increasing demands for more efficient production and managerial technology according to globalization and free trade system. At the same time, three steps of organizational restructuring in 1998 and 1999 resulted in decreased number of organization and manpower, thus, resulting confusion in implementing extension services. To cope with the international and national challenges, Korean agricultural extension services should try paradigm shift including the followings; 1. To establish identity of agricultural extension services in Korea through making laws and regulations in terms of concept, roles, principles. implementation and methods. 2. To implement vitalizations plan through enhancement of national extension service such as food production. raising local specialty products for domestic consumption and producing strategic agricultural products for export. expanding capability of rural women, increasing opportunity for management consultation, supporting digital technology information, and promoting morale and capability of extension educators. 3. To reform agricultural extension system through adjusting the functions of extension service of the Rural Development Administration, regionalizing city and county extension center to provincial level, and changing the status of directors of extension centers from city /county to national government.

A total of 437 landraces of rice from Vietnam were analyzed for total seed protein by SDS-PAGE and phenol reaction. The different types of glutelin $\alpha$ subunits were detected. The level of wx protein with 60kDa molecular weight was divided into 3 groups, corresponding to non-glutinous, intermediate and glutinous starch types. Based on the variation in seed storage protein and wx protein, landraces were classified into 7 groups. Frequency distribution of types A and B of glutelin $\alpha$ subunits changed with the latitude at which rice landraces were collected. Geographical cline for phenol reaction was detected.

The applications of Distributed Generation (DG) in a smart distribution grid environment are widely employed especially for power balancing and supporting demand responses. Using these applications can have both positive and negative impacts on the distribution system. The sizing and location of their installations are the issues that should be taken into consideration to gain the maximum benefit from them when considering the economic aspects. This paper presents an application of the Bat Algorithm (BA) for the optimal sizing and siting of DG in a smart distribution power system in order to maximize the Benefit to Cost Ratio (BCR), subjected to system constraints including real and reactive power generation, line and transformer loading, voltage profile, energy losses, fault level as well as DG operating limits. To demonstrate the effectiveness of the proposed methodology and the impact of considering economic issues on DG placement, a simplify 9-bus radial distribution system of the Provincial Electricity Authority of Thailand (PEA) is selected for the computer simulation to explore the benefit of the optimal DG placement and the performance of the proposed approach.

Skeletal deformities are significant problems that affect the growth and commercial value of fish reared in hatcheries. However, studies of bone metabolic process related to skeletal deformities are limited. We investigated the potential correlation between bone deformities and plasma calcium, phosphorus, and estradiol-$17{\beta}$ levels in reared red spotted grouper (Epinephelus akaara) juveniles. We collected E. akaara frys from private farms at 110, 140, 180 and 300 days after hatching (DAH), and classified the normal and deformed fish by observing their external shape and inner frame by soft X-ray. We also analyzed the calcium, phosphorous, and estradiol-$17{\beta}$ levels in their plasma. A comparison between normal and deformed fish, indicated that calcium and estradiol-$17{\beta}$ levels were higher in deformed fish than in the normal at 180 and 300 DAH. The level of phosphorus was also higher in deformed individuals than in normal fish, but only at 300 DAH. These results suggest that skeletal deformities are associated with increases in plasma calcium, phosphorus, and estradiol-$17{\beta}$ levels.

The core purpose of the system proposed in this paper is to help learners pursue proactive and self-oriented education by allowing learners to proactively configure their own content, that is, learners no longer have to be restricted by prescribed sequence of lectures. Although a variety of standardization and Learning Management System (LMS) were produced to develop and effectively manage web contents in response to active diffusion of internet application, practical changes to assist online learners are not yet to be found. In this paper, I would like to introduce a LMS that can support self-leading education by providing various types of learners at Virtual University with delicately organized educational contents for maximum efficiency. The system allows a learner to select a lecture or a chapter which has been presorted to meet his educational needs and intellectual ability. In general, most LMSs cannot meet every individual's educational needs because they structure their programs by letting learners simply choose from a list of available lectures at prescribed level or difficulty. However the Self-Leading LMS eliminates such boundaries by allowing learners to choose contents and difficulty within the limit set by their own educational competence.

This research was intended to have a grasp of the problems in physical education curriculum, After making an alternative plans of effective management. those were integrated and analyzed their own relations on the purpose of suggesting alternative plans to foster professionality of physical education teacher in order to improve real class of physical education. For this purpose, I referred to sundry records related with instruction of physical education teacher and also conducted a survey with 10 interviews such as researchers of central government education administration, and school commissioners in the ministry's provincial offices of education, professors in the university of pre-teacher training, and teachers involved in physical education. The conclusions were as follows; Physical education curriculum should be organized to reduce and diversify of the sport contents in various levels. Also, it should instruct students based on physical educational knowledge, and it is made up to know the achievement of goals through evaluation tools and development of rules having propriety and reliability. Such a physical educational curriculum developed from real class should inform continuously throughout the Ministry of Education & Human Resources Development and educational organization of physical education teachers and network of the school and mass media. So, it makes most people's recognition raise up, and we need discretionary authority of physical education teacher about time allocation of 45 minutes or 50 minutes for variety of lessons. And we need systematic installation such as reorganization of completion field in level of school.
