In order to investigate the storage stability of seed oils, such as perilla oil, sesame oil, rapeseed oil and peanut oil, the oil seeds and seed oils were stored for 40 days at room temperature (20℃-30℃), 4℃ and -20℃, respectively, than the acid value, peroxide value, TBA value and iodine value of the oil and oil extracted from the stored seeds, were determined. The results were as follows; Acid value, peroxide value and TBA value of these oils were increased sharply during storage at room temperature. Among seed oils, perilla oil was least stable and peanut oil was most stable. The oils extracted from stored seeds were more stable than the stored oils, thus the patterns of oxidation of the oils, extracted from stored seeds at room temperature, were same as that of oils, stored at -4℃. Generally, the quality of seed oils could be preserved when the crude seed oils were stored at the temperature below -20℃ and oils seeds at 4℃, respectively.

The object of this study was investigation of the appreciable cooking condition in seven wild grasses, an evening primerose(Oenothera lamarckiana Seringe, S₁), a spiderwort(Commelina Communis L. S₂), the flower of a convolvulus(Calystegia Ja-ponica form Vulgaris gaea, S₃), So Ru Jaeng Yi(Portulaca Oleracea, S₄), Shoe Bi Rum(Portulacae Oleracea L, S_5), O Yi Pul(Sanguisorb aOfficinalis, S_6), Jip Sin Na Mul(Agrimonia poisa var. Japonica Nakai, S_7), in order to find out the importance as an useful vegetable. In this work 7 wild grasses with different soaking solutions and boiling conditions were examined to investigation the preference factors by sensory evaluation. Results of sensory evaluation for samples showed a significant difference at 1% and 5% level There were high significant differents in samples boiled for different time about astringent taste, bitter taste, perfume, green color and grassy smell at 1% and 5% level. In cooking methods of 7 samples, Namul was liked best and Guk, Salad and Fritter were followed. The condiments which were used for seasoning Namul were Gochujang, Soy Paste, Salt. Gochujang was most preferred.

Objectives : Nowadays many studies with MRI have reported structurai abnormalltles of corpus callosum of schizophrenic patients. However, the results are various and inconstant. In this study, we attempted to identify structural change of C O ~ U S cailosurn. Method : We measured the size of corpus callosum of the 24 schizophrenia patients (male 11, female 18) who were diagnosed by DSM-IV (19943, visited at department of psychiatry, catholic university hospital of Daegu from January 2002 to December 2003, by using midline sagittal slice of MRI. These results were compared with the size of corpus callosum of 25 controls (male 7, female 78). We divided corpus callosurn into 7 areas. We calculated and compared the areas of each subregion, mid-sagittal cerebral area, and entire corpus callosum. The results were analyzed by independent t-test. Result :When we compared subregion to corpus callosum adjusted wth mid-sagittal cerebral area, schlzoph-renia patients had significantly smaller genu (1.64k0.32 vs. 1.43k0.26 p<O.O5) and splenium (2.16f0.27 VS. 1.96+0.30 ; ~(0.05). Similarly, the ratio of total corpus callosum to midline sagittal cerebral area (%)(7.50*0.72 vs. 6.90t0.82 ~(0.05) was significantly smaller In schizophrenia than control group. Conclusion : In this study, we found significant differences in corpus callosum between schizophrenic patients and normal control group.

본 논문에서는 문맥 종속형 유사음소 단위 모델에 기반한 대용량 어휘인식에 관한 실험을 수행하였다. 한국어의 발음 및 음운 특성을 고려하여 선정한 50개의 단일 유사음소 모델로부터 총 593개의 이중음소(diphone)를 구성하여 인식의 기본단위로 설정하혔다. 유사 음소 및 언어 모델 데이타베이스로부터 발음사전을 구성하고 기본단위 인식시 탐색 공간을 줄이고 성능을 향상시키기 위해 bigram을, 구문단위로 분할한 문장인식에 대해서는 unigram을 적용하였다. 실험 결과, 유사음소단위 인식에서는 69.16%의 인식률을, 문장인식을 거친 최종 인식률은 87.36%의 성능을 나타내었다. In this paper, We studied and carried out an experiment on speech recognition of large vocabulary based on diphones. We set up 593 diphones for basic PLUs from 50 phonemes considering pronunciation and phonemic characteristic of Korean language and constructed the lexicon from the database of phoneme and language models. Bigram was applied to recognition of PLUs to reduce search space and increase efficiency of recognition and unigram was applied to language model divided by phrase. As a result, experiment about the sentence recognition shows that diphone models would have 9.14% better performance than monophones.

This study was conducted to investigate the nutritional composition of several vegetables, such as green pepper, squash, cucumber, tomato, perilla leaves, lettuce, Chinese cabbage, radish leaves and roots which were grown in vinylhouse. Proximate components and vitamins, such as thiamin, riboflavin and ascorbic acid of these vegetables were determind. Generally, vinyl house-grown vegetables showed high moisture and minerals and low protein, fat, sugar and fiber than field grown vegetables. On the other hand, vitamin contents showed different pattern depending on the kind of vegetables.

Mulberry leaves arc believed to be a potent inhibitor of intestinal α-glycosidase and the digestion of sucrose in the small intestine. Mulberry leaves are also known to help prevent the postprandial hyperglycemia. The objective of this study was to elucidate the functionality and anti-hyperglycemic effect of mulberry leaves, and to develop a functional drink using mulberry leaf, silk peptide and oriental medicine. Several mixtures of mulberry leaf extract, silk peptide and oriental medicine were made for the purpose of manufacture and formulation of products. These mixtures were tested to check the α-glycosidase inhibition effect to find the best formula. The optimum conditions for a mulberry leaf hot water extract were that the size of leaf was under 3㎜, the amount of leaf needed 50~100 g/L, extraction temperature 90℃ and extraction time 2 hr. The yield of extraction was 20~25%. The anti-hyperglycemic effect of mulberry leaves was at maximum when the concentrations of mulberry leaf extract and silk peptide were 1% and 0.1% respectively.

Castleman' s disease is a rare, reactive lymphoid proliferation of unknown cause and pathogenesis. Depending on histololgic findings, it has been divided into two distinct histologic subtypes that include hyaline-vascular type(90%) and plasmacell type(10%). This disease occurs most commonly in mediastinal lymph nodes and cervical lymph nodes, inguinal lymph nodes respectively. But occurs rarely in retroperitoneum. We report a case of hyaline-vascular type asymptomatic Castleman' s disease of the retroperitoneum in a 47-year-old man.

The purpose of the paper is to suggest a decision supporting method applicable to the real world for determining the locations of logistics centers and their service areas. It doesn't simply suggest the unique optimal locations minimizing the related logistics costs. In stead, it computes the logistics costs and the service level for each logistics network alternative. For the given network the optimal flow quantities from suppliers to logistics centers and from logistics centers to customers can be obtained by solving the minimum cost allocation model. By adding the transportation costs obtained from the minimum cost allocation model and other fixed and variable operating costs of location centers the total related logistics costs can be calculated. It allows the decision maker to consider both of the aspects of quantity and quality.
