This study was conducted to investigate the quality characteristics of peach jelly following the addition of various gelling agents (locust bean gum, carrageenan, xanthan gum). The various gelling agents were added to peach jelly at five levels (1.0, 1.5, 2.0, 2.5 and 3.0%), after which their effects on physicochemical properties, textural properties and sensory qualities were investigated. The total titratable acidity (TTA) of peach jelly was decreased with increases in gelling agent. Additionally, the sweetness and pH of peach jelly increased significantly as the amount of various gelling agents increased. Moreover, the lightness (L-value), redness (a-value) and yellowness (b-value) of peach jelly was decreased as the amount of gelling agent. Furthermore, the hardness, gumminess and chewiness of the peach jelly increased as the amount of gelling agent increased. Finally, the overall acceptance was higher for jelly containing 2.0% added gelling agent than for other samples. Based on the results of this study, it is recommended that mixed gelling agents be added to peach jelly at 2.0%.

본 실험에서는 가공 두부를 천연항균소재인 자몽종자추출 물의 유도체에 침지 처리한 후 꺼내어 상온에서 저장하면서 가공 두부의 품질(총균수, 수분 함량, 조지방의 함량, 조단백의 함량, 표면색도)변화에 미치는 영향을 무처리 대조구와 비교하면서 조사하였다. 천연항균소재의 희석액에 침지처리한 가공두부는 대조구에 비하여 수분함량, 조단백 및 조지방 함량이 높게 나타났으며, 총균수는 천연항균소재 처리구의 증가폭이 무처리 대조구에 비해 감소하는 경향으로 나타났으며 대장균수도 압도적으로 낮은 간을 보여 주었다. 아울러, 처리구의 표면색도는 대조구에 비하여 백색도를 두드러지게 나타내었다. 이와 같은 결과로 볼 때, 천연항균소재의 침지처리는 가공두부의 선도유지 기간을 연장할 수 있는 효과를 기대할 수 있었다.

A new protection coordination algorithm in Multi-Agent based distribution automation system is proposed in this paper. Distribution network protection coordination is acted by normal state distribution operation. But, in more and more complex distribution network structure, it has a big problem that central server processed all measurement data, coordination setting and controls for operation. So, a algorithm to change coordination setting is proposed automatically in terminal devices which Recloser and OCR to include Multi-Agent concepts in distribution network.

전자 상거래와 같이 통신 보안이 요구되는 응용 분야에 에이전트 기술을 효과적으로 적용하려면 에이전트 기술과 보안 기술의 결합이 요구된다. 본 논문은 공개키 기반 구조 기술과 에이전트 기술을 결합하여, 기밀성(privacy), 완전성(integrity), 신원 확인(authentication), 부인 방지(non-repudiation)등의 보안 기능을 지원하는 다중 보안 에이전트 엔진 모델을 제안한다. 각 에이전트는 구조적으로 에이전트 엔진 계층과 에이전트 응용 계층으로 구성된다. 제안한 보안 에이전트 모델의 설계에는 자가 송수신 메시지, 보안 채널 그리고 에이전트 응용 계층에서의 KQML(Knowledge Query and Manipulation Language) 메시지와 에이전트 엔진 계층에서의 메시지의 구분이라는 개념들이 사용되었다. 제시된 보안 에이전트 엔진 모델이 제공하는 에이전트 언어는 기존 에이전트 언어인 KQML의 내용층 및 메시지층에 대한 아무런 수정이나 제약 조건 없이 통신 계층만을 확장하여 보안 기능을 표현하며, 에이전트간의 보안 통신은 에이전트 언어 상에서 투명하게 표현되는 보안 채널을 통해 이루어진다는 특징을 갖는다.

Cyperus rotundus L. (Cyperaceae) has been used as an analgesic, antiinflammatoty agent, diuretic and emmenagoga in folk remedies. Cyperi Rhizomata, processed and unproces sed, were extracted with MeOH and fractionated with petroleum ether (Pet. Ether), $CHCl_3$, BuOH, water. In order to investigate the effects of their fractions on kidney function of acute renal failure rats induced by $HgCl_2$ urinary volume, BUN, Creatinine, Uric acid were determined. The diuretic effect of processed Cyperi Rhizoma was significantly increased in renal failure rats, on serum chemical parameters, the significant inhibition of BUN (blood urea nitrogen) of processed Cyperi Rhizoma was revealed.

This study was conducted to develop fresh-cut and processed pears. After treatment of citric acid (1%) or N-acetylcysteine (0.2 M), and co-treatment of citric acid (1%) and N-acetylcysteine (0.2 M) into the pears c.v. 'Wonhwang', the quality changes of pears during cold storage ($1^{\circ}C$) for 10 days were investigated respectively. Pear quality and the taste of pears increased much more in those treated with anti-browning agents than those in the control group at 10 days after anti-browning treatment and cold storage. Changes in Hunter b values of pears treated with 0.2 M N-acetylcysteine were insignificant. Those with Polyphenol oxidase (PPO) activity and ethylene production were had the most decreased effects and those with the phenolics compound contents were the most lowered. Firmness of fruits increased in treatment of 0.2 M N-acetylcysteine + 1% citric acid solution. The amount of respiration decreased in the application of 1% citric acid solution. Consequently, fruit freshness can be maintained more effectively by the treatment of the anti-browning agent compared to non-treatment, even if the effectiveness were different among different kinds of anti-browning agents.

This study was carried out to give some help for housewives recognizing the desirable purchase of processed foods and food additives. This results were abtained as follows; In case of purchase action for processed foods of housewives confirmation of manufacturing date was the highest point(4.62). When housewives bought processed foods they considered the taste of them as first, and frequencies of processed foods intake showed the ratio of 46.6%, also it was shown to be used once a week. The order for use of processed foods were milk, milk products(butter, cheese, yoghurt, lactic bacterium beverage) 40.2% >canned foods 22.6% >meat products(ham, sausage, bacon) 20.9% > jelled fish 16.3%. Most of housewives wanted to have the knowledge and information for food additives at the highest point(4.11). The interest about food additives of housewives was shown to the order of synthetic preservative 3.86 >chemical seasoning 3.74 >synthetic sweetener 3.59 >synthetic coloring agent 3.53. Also, it was shown to be thought that the hazard factors effected on food safety were agricultural chemical residue(30.9%), environmental pollution(25.2, food additives(23.0%), and microorganism contamination(20.9%).

Psoralen is used in the treatment of vitiligo and angelicin(isopsoralen) is a photosensitizing agent. A reversed-phase high performance chromatographic method was developed to determine the contents of psoralen and angelicin from Psoraleae Semen and processed Psoraleae Semen. The contents of psoralen and angelicin from Psoraleae Semen showed 0.39% and 0.34% respectively. Processing Psoraleae Semen showed that increased the contents of psoralen (0.52%) and angelicin (0.50%).

Ubiquitin-proteasome proteolytic system plays an important role in selective protein degradation and regulates cellular events including apoptosis. Cancer cells have been shown to be more sensitive to the proapoptotic effects of proteasome inhibition than normal cells. Thus, proteasome inhibitor can be potential anticancer agent. Since the MeOH extracts of psoraleae semen and processed psoraleae semen showed potent proteasome inhibition activity, the fractions of the extracts were evaluated on the activity to screen the proteasome inhibitors. The $CHCl_3$ fr. of the processed psoraleae semen showed the most potent activity, of which chemical investigation led to two coumarins, psoralen and isopsoralen. Their structures were determined by spectroscopic methods such as $^1H-NMR$ and EIMS spectra.
