In a previous study, we developed a new food additive as an egg yolk antibody (IgY) against carbohydrate digestion enzymes for the regulation of blood glucose level and weight control. The IgY delayed and decreased the increment of blood glucose level after administration of sucrose in human being by 30% in 20∼30 min. We also developed a lipase inhibitor as a water extract of two kinds of herb, Platycodon grandiflorum and Solanum melongena. Twenty three volunteers were subjected to the intake of the egg yolk IgY plus the herbal extracts for 50 days. In average, the treated subjects appeared to lose 1.96 ㎏ of body weight and 3.4 ㎏ of body fat mass during the treated period. Furthermore, Panniculus adiposus and breech size were significantly decreased during the experimental period. Above results suggested that the administration of the dietary additives composed of egg yolk IgY and natural herbal extract improve the obesity by the decrement of body weight and body fat mass.

An algorithm to automatically extract coordinate and time information from optical observation data of geostationary orbit satellites (GEO satellites) or geosynchronous orbit satellites (GOS satellites) is developed. The optical wide-field patrol system is capable of automatic observation using a pre-arranged schedule. Therefore, if this type of automatic analysis algorithm is available, daily unmanned monitoring of GEO satellites can be possible. For data acquisition for development, the COMS1 satellite was observed with 1-s exposure time and 1-m interval. The images were grouped and processed in terms of “action”, and each action was composed of six or nine successive images. First, a reference image with the best quality in one action was selected. Next, the rest of the images in the action were geometrically transformed to fit in the horizontal coordinate system (expressed in azimuthal angle and elevation) of the reference image. Then, these images were median-combined to retain only the possible non-moving GEO candidates. By reverting the coordinate transformation of the positions of these GEO satellite candidates, the final coordinates could be calculated.

This paper proposed on the effective cutting conditions of cage motor rotor by turning. If you want introduce automatic manufacturing system into the cutting process of cage motor rotor, the selections of effective cutting conditions are necessary. The cutting process of cage motor rotor requires the precision and the out of roundness of cage motor rotor. The surface roughness of cutting face, it is very important factor with effect on the magnetic flux density of cage motor rotor. The purpose of this study is to find out the effects of cutting conditions. Upon adapting this results, we will improve the production rate in the cutting process of cage motor rotor. As a result, the selection of cutting conditions are important factors to production rate. And these are chosen by the investigations of cutting characters and surface roughness. The experimental result, showed that the increase of cutting speed caused the decrease of cutting force and the high surface integrity. The increase of feed rate and increase of depth of cut caused the increase of cutting force and surface roughness. Thus, the effective cutting conditions of cage motor rotor by turing are cutting speed 291m/min, feed rate 0.10mm/rev, depth of cut 0.05mm.

Antioxidative activities (AA) of mustard leaf kimchi (MLK) by the addition of optional ingredients among selected minor materials were studied. In order to determine AA of MLK with different spices, the model systems of ground cooked beef with green onion, garlic, and red pepper powder were prepared and stored for 4 weeks at 4℃. AA of red pepper added group was stronger than those of others. AA of red MLK was relatively higher than that of (green) MLK. For the enhancement of AA of MLK, another model systems were prepared with the selected antioxidative optional ingredients, which were bonnet bellflower root, leek, burdock, sea tangle, sea mustard, seastaghorn at the level of 2% or 4%. The extracts of water, 75% methanol and hexane of MLK, bonnet bellflower root added MLK, and seastaghorn added MLK had a considerable AA with the inhibition of peroxide formation during the autioxidation of linoleic acid mixtures in aqueous model systems at 37℃. Therefore, AA was more effective in MLK containing specific optional ingredients than that of MLK alone significantly.

The purpose of this study is to analyze the terms, Leisure, Recreation, and Play in an attempt to explain the complex phenomena of the terms. It is achieved by reviewing past literature. The reasons for developing definitions and ways of measuring these terms are to help both the practicing leisure professional and those who study the leisure phenomena. By defining and measuring these terms, we can more accurately predict the consequences and actions of our work as leisure professionals. One can also be provided a better understanding of the phenomena of the terms. For the research methodology, a descriptive study, which is to present a detailed picture of the phenomena hilt does not attempt to test or build theoretical models, was used for this study. On the basis of the results analyzed in the study, findings were made as follows. Leisure can be viewed from a number of different perspectives. Some theorists suggest that leisure is an element of time, whereas others have perceived it as a set of unique activities in which individuals participate. Recreation can be viewed as a wholesome activity in which individuals participate in their leisure time. Recreation is a more commonly used and understood term among the general public than either leisure or play. Play is an exceedingly interesting, yet diverse and different topic to identify. Many theories have emerged to describe play. However, today it has no generally accepted explanation or definition. Unfortunately, confusion interpreting leisure, recreation, and play was found in this study. Based on the results of this study, this researchers offer one possible view of the terms for the further studies. The new terms defined are provided.

Arteriovenous fistula of uterus is a very rare cause of massive uterine bleeding. However, it is important to make a rapid and precise diagnosis when it does occur, because life-threatening massive vaginal bleeding may occasionally be a symptom of this disease. Uterine curettage or surgical trauma can cause vascular abnormalities, including pseudoaneurysms, acquired ateriovenous malformations, ateriovenous fistulas, and rupture of vessels. The diagnosis is made by angiography, and gray scale ultrasonography, color and duplex doppler ultrasonography, computed tomography, magnetic resonance imaging is helpful. Ultrasonography is the most commonly performed initial imaging examination for evaluation of abnormal uterine bleeding. Color and duplex Doppler US is an appropriate modality for the detection and diagnosis of uterine ateriovenous malformations and for follow-up after embolization. Transcatheter embolization has replaced hysterectomy as the treatment of choice in women wish to retain thier fertility. A case of arteriovenous malformation of the uterus which was diagnosed by ultrasonography. So reported this case with a brief review of the literature.

박영식,최홍란 전남대학교 치과대학 2001 구강과학 Vol.13 No.1

Nasopharyngeal carcinoma is a common neoplasm of the head and neck, and commonly found in Southeast Asia. Epstein ­ Barr virus(EBV) is found within the malignant cells in most cases of nasopharyngeal carcinoma. The p53 gene has been implicated as a tumor suppressing gene in many types of human cancers, but the frequency of mutations varies in different cancers. To find out the correlation between EBV infection and p53 mutation in nasopharyngeal carcinoma, we evaluated the presence of EBV using EBER ­ 1 in situ hybridization and a mutation of p53, using PCR ­ SSCP analysis and DAN sequencing method. We examined nasopharyngeal specimens from 33 patients, histologicaly consisting of 27 cases of nonkeratinizing squamous cell carcinoma (WHO ­ Ⅱ) and 6 cases of undifferentiated carcinoma (WHO ­ Ⅲ) according to the World Health Organization claasification. EBER1 were detected in 14 of 33 (42.4%) cases. Positive hybridization signals were restricted to the nuclei of tumor cells. Of 14 cases 14 cases, 11 out of 27 (40.7%) cases of WHO ­ Ⅱ, and 3 out 6 (50%) cases of WHO ­ Ⅲ were positive. 33 biopsy specimens were analyzed by PCR ­ SSCP for p53 gene mutations. Our study concentrated on exons 5 through 9 of the p53 gene. However, we did not detect any mobility shifts n exon 5/6, 7 and 8/9 of the p5 gene in comparison to the banding patterns of the normal control. The reliability of the SSCP analysis was confirmed by sequencing five randomly chosen specimens for the exon 5 ­ 9 region. Among five cases, 4 out 5 cases were EBER1 positive and histologially WHO ­ Ⅱ, and 1 out of 5 cases were EBER1 negative and WHO ­ Ⅲ. We detected point mutation in 3 cases were EBER ­ 1 positive and WHO ­ Ⅱ. No alteration of the exon 7 and 8/9 of the p53 sequence was observed. Alteration occurred in 2 out of 3 cases; GCC was replaced by GTC at codon 131, resulting in a change in amino acid sequence from alanine to valine. In one 3 cases, TCC was replaced by TTC at codon 149, resulting in a change from arginine to arginine. Based on the above results, this study shows correlation between the presence of EBV and mutations of the p53 gene, suggesting contributions to malignant transformation in nasopharynx. We need to futher investigate this situation to understand the stepwise progression of nasopharyngeal carcinogenesis.

This research was performed the diffraction of irregular waves due to the semi-infinite breakwater. As for the simulation of irregular waves, the directional spreading function was divided by 10, 20, and 36 respectively under the condition of a constant division M=10 of frequency spectrum. Also two kinds of parameter Smax=10 and 75 were adopted for investigating the dissipation effect in the sheltered region. As the results of comparing with division number of the directional function, some differences were found between N=10 and N=36, but no any remarkable variance were found in the comparioson between N=20 and N=36. As for Comparing with the values of Smax, the diffraction coefficient distribution for Smax=75 was lower than that of Smax=10, and also irregular diffracted wave heights were almost lower than regular waves. As the verification step, the results of diffraction wave height and period's ratio obtained by this study were compared with Goda's results, a good agreement was found between them. Therefore the method of the this study may be useful for estimating diffraction wave height and layout of breakwater.
