The objective of this study was to investigate the effects of administration methods for on Garcinia cambogia on blood Garcinia cambogia concentration and antioxidative levels. Rats were divided into three groups: G1 (normal group), G2 (one administration of Garcinia cambogia extract 2,800 mg/kg b.w.), G3 (three separate administrations every 6 h of Garcinia cambogia extract 750, 850, and 1,200 mg/kg b.w. for 18 h). Blood samples were collected every hour, and animals sacrificed 18 h after the oral administration of Garcinia cambogia extract. We examined changes in the serum concentration of Garcinia cambogia by HPLC analysis. Two hours following an oral administration of Garcinia cambogia extract (2,800 mg/kg b.w.), serum Garcinia cambogia levels reached their maximum, but gradually decreased until 10 hours when it was no longer detectable. In contrast, serum Garcinia cambogia levels under G3 administration were maintained above a certain level after 18 h. To determine whether this level of Garcinia cambogia could affect blood oxidative levels, we measured serum lipid peroxidation by TBARS levels. TBARS levels from G3 treatment were significantly lower than G1 and G2. To analyze other antioxidative activities, radical scavenging activities were measured by the DPPH and ABTS radical scavenging assays. There were no significant differences between the groups in DPPH radical scavenging activity. However, ABTS radical scavenging activity significantly increased with G3 treatment compared with G1 and G2. In conclusion, our data show that three times administration of Garcinia cambogia every 6 h may helpful for maintaining serum Garcinia cambogia levels and antioxidative effects.

The effects of aronia powder on the rheological and sensory characteristics of Sulgidduk were investigated. The moisture content of Sulgidduk ranged from 40.86 to 44.40%; however, addition of aronia powder to Sulgidduk tended to decrease its moisture content. With regard to the rheological properties, the addition of aronia powder decreased the hardness, springiness, adhesiveness, cohesiveness, chewiness, gumminess, and brittleness of Sulgidduk. Chromaticity determination revealed a decrease in L and b values, while the a value increased with the increasing amounts of aronia powder. Total polyphenol, total flavonoid and total anthocyanin contents increased with the increasing amounts of aronia powder. Antioxidant activity, measured by DPPH and ABTS radical scavenging activities, was significantly higher than that of the control, and increased proportionally with the amount of aronia powder. During 4 day storage, the growth of total aerobic colony and coliform content significantly decreased with increasing levels of aronia powder in Sulgidduk. Sensory evaluation demonstrated the best score in color, taste and overall acceptance when aronia powder was added at 5% of rice powder. These results suggest that 5% aronia powder can be added for the preparation of Sulgidduk.

Genus Nitrospira and Nitrobacter species are the key nitrite-oxidizing bacteria(NOB) in nitrifying wastewater treatment plants. It has been hypothesized that genus Nitrospira are K-strategists(low $K_6$ value) that can exploit low amounts of nitrite more efficiently than Nitrobacter. In contrast, Nitrobacter species are r-strategists(high $V_{max}$) that can grow faster than Nitrospira. It has also been known that the availability of organic compounds and dissolved oxygen as well as nitrite affects the distribution of NOB. In this study, we determined the distribution and competition of NOB in wastewater nitrification systems where nitrite, organic compounds, and dissolved oxygen concentrations were compositively varied. For the purpose, several compounds of the laboratory-scale nitrificaiion bioreactor and full-scale $A_2O$ wastewater treatment plant and their distribution of NOB were analyzed and compared. The analysis showed that Nitrobacter was the dominant NOB in nitrification bioreactor where average nitrite was maintained at 5 mg-N/L with very low organic concentration in aerobic condition, whereas Nitrospira was the dominant NOB in full-scale $A_2O$ plant where nitrite was maintained very low and organic compounds were maintained relatively high in alternating aerobic-anoxic condition. The result indicates that nitrite concentration is more critical factor than organics and dissolved oxygen which determines the dominant NOB in nitrification system and it is confirmed that Nitrospira and Nitrobacter showed the characteristics of r-strategist and K-strategist, respectively.

This study was performed to examine the quality characteristics and antioxidant activities of the sponge cakes containing different concentrations (2-10%, w/w) of aronia powder (AP). The specific gravity of the dough and the baking loss rate were significantly increased with higher AP content. The specific volume, height, volume index, and pH were significantly decreased with the increase in AP. The lightness and redness values increased, while the yellowness values decreased with increasing amounts of AP. Textural characteristics, such as hardness, gumminess, and chewiness significantly increased on addition of AP. The DPPH radical scavenging activities of the cakes increased significantly with the increase in concentration of AP. In sensory evaluation, the group with cakes containing AP at 2% concentration was ranked higher than other cakes with respect to all parameters, except for color. Therefore, the results of this study suggest that sponge cakes prepared with 2% AP is the most suitable product, based on its sensory characteristics and antioxidant activities.

This study aims to implement a model for developing participatory labor archives for shipbuilding labor archives in young-do, Busan, and to find possibilities of building digital labor archives as participatory ones. The methodology of locality documentation has been applied, and locality archives accepting participation of people with experiences from shipbuilding industry have been examined. Omeka was applied because it is an open-source software and provides additional functions which support various user participations and web-publishing. Following the the model, firstly, a preliminary investigation was conducted and research of participatory agents and records was proceeded. Secondly, it collected and described information of the agents and records by institutions with records and provenance. Thirdly, it developed archival contents specific to events, persons and workplaces in association with archival information. For the follow-up study, plugins were installed and tested to apply for further experiment with participation.

영유아기는 자신에 대한 긍정적 사고를 바탕으로 남과 더불어 살아 갈 수 있는 능력의 기초를 이루는 사회 정서적 발달의 결정적 시기로서 영유아기의 발달이 성인기까지의 성공적인 삶에 영향을 미치지만, 잘못되는 경우 세대를 넘어서까지 전이되는 문제를 유발할 수 있다. 영유아의 발달에 영향을 미치는 요인 중에서도 가장 중요한 것은 어머니와의 상호작용이라 할 수 있다. 따라서 어머니가 자녀에게 미치는 영향은 지금까지 지속적으로 연구되어 왔으며, 그 중에서도 어머니의 양육태도에 연구의 초점이 맞추어져 왔다. 그러나 양육자가 보이는 일반적인 경향을 나타내는 양육태도보다는 부모역할지능이 오히려 부모의 양육행동을 구체적으로 평가할 수 있는 현실적인 도구라 할 수 있다. 이에 본 논문은 맞벌이 가정의 증가로 보육시설에서 생활하는 시간이 많은 영유아의 내재화 및 외현화 문제에 어머니의 부모역할지능이 미치는 영향을 분석함으로써 부모들이 점차 줄어드는 영육시간에도 불구하고 보다 성공적인 영유아 발달을 꾀하는데 도움이 되는 정보를 제공하는 한편 영유아의 보육시설에서도 영유아의 문제행동을 치유할 수 있는 프로그램의 개발에도 유익한 정보를 활용되도록 하고자 한다.

When an ending which begins with 'a/a'combines to a stem,'a/a'can be deleted.Especially when ot combines to an h-irregular verb,it is represented as a variant like '-a-','-e-','-ia-',or'-ie-'.In order to analyze the variants of 'a/a',we suggest the format of a grammatical morpheme dictionary which is represented as a binary tree and several procedures which process the variants so that the unexpected errors can be removed which occur frequently when we analyze Korean worl phrase.
