This study was conducted to determine the polymorphism of transferrin exons 13, 15 and 16 by Single-Strand Conformation Polymorphism(SSCP) analysis and to compare their genotypes of Cheju horse Group I (Cheju Institute), Cheju horse Group II (farms), and Thoroughbred (KRA). SSCP of transferrin exon 13, 15, and 16 showed two (A, B), three (A, B, C) and three (A, B, C) codominant alleles, respectively. The Group I and Thoroughbred showed the similar frequencies of allele A and B in transferrin exon 13, but only allele A was observed in Group Ⅱ. In transferrin exons 15 and 16, the frequencies of each allele were different in each Groups. The multiple allele frequencies in exons 15 and 16 suggested that the genotyping of this locus could be used to identify an individual and to test the parentage of offspring. The probability for parentage exclusion were 0.46 and 0.374 for exons 15 and 16 for Cheju horse Group I. Among the 13 combined genotypes of exons 13, 15 and 16, the genotype AA-AB-AB (0.372) is the most common in Cheju horse Group I, but genotype AA-AA-AA is common in the Cheju horse Group II (0.366) and Thoroughbred (0.767). The present study showed two new SNP, which was at the cDNA position 1626 (A/G) in B allele of the exon 13 and 2075 (C/T) in C allele of the exon 16 resulting in amino acid change (Threonine $\longrightarrow$ Methionine). Result showed that polymorphism of exons 13, 15 and 16 in Cheju horses was as high as in Thoroughbred and there was a differences of transferrin allele frequencies in Cheju horses.

Mutations in Fused in Sarcoma (FUS) have been identified in patients with amyotrophic lateral sclerosis (ALS) or Frontotemporal Dementia (FTD). Pathological FUS is mis-localized to cytosol and forms aggregates associated with stress granules (SG), while FUS is normally localized to nucleus. However, it is largely unknown how pathological FUS forms SG-aggregates and which domains are responsible for this process. In this study, we examined cellular localization and aggregation of ALS-linked FUS missense mutants (P525L, R521C, R521H, R521G), analyzed the domains responsible for cytosolic FUS aggregation in HEK293T cells, and confirmed this in cultured mouse neurons. To do this, we firstly generated missense mutants of FUS and then examined their cellular localization. We found that P525L was mostly mis-localized to cytosol and formed FUS-positive SG aggregates while R521C, R521H, or R521G was localized to both nucleus and cytosol. To further characterize the domains required for aggregate formation of cytosolic FUS, we generated different domain-deletion mutants using FUS-∆17 which has a deletion of nuclear localization signal. Interestingly, cytosolic FUS without SYGQ and RGG1 domain or cytosolic FUS without RGG2-ZnF-RGG3 domain did not form FUS-positive SG aggregates, while cytosolic FUS without RRM domain generated more aggregates compared to FUS-∆17. Taken together, these data suggest that SYGQ-RGG1 or RGG2-ZnF-RGG3 domain contributes to formation of cytosolic aggregate, while RRM domain might interfere with FUS aggregation. Therefore, our studies will provide important insight for understanding cellular pathogenesis of neurodegeneration associated with FUS aggregate as well as finding therapeutic targets for ALS or FTD.

This study was done to analyze nutrition counseling services in health promotion center and to investigate demands of subjects for nutrition services. Data was collected through the survey of 90 subjects. The results were as follows. The results of people receiving nutrition services showed that 58.5% of the counseling group and 46.4% of the non-counseling group answered having experience with nutrition services. And 50% of them received nutrition counseling through individual counseling. Diet therapy with health check-up results also appeared the highest in contents of nutrition counseling. As a source of nutrition information and health knowledge, subjects relied heavily or most on the TV, internet, books, magazines, and newspapers. On the other hand, they relied much less on advice from dietitians, nutritionists, medical doctors and nurses. The experience of receiving nutrition services and thinking about nutrition education related positively. It showed that the counseling group (95.1%) was significantly higher than the non-counseling group (80.5%) in necessity of nutrition assessment. But, necessity of nutrition counseling wasn't significantly different between the two groups. The method of nutrition counseling subjects preferred was individual consultation. The subjects answered to having need of analysis and evaluation of nutrient intake and calorie prescription in nutrition assessment and individual nutritional status results explanation in nutrition counseling. In conclusion all people visiting health promotion centers need nutrition service of some kind.

The objective of this study was to test the effect of catalase on penetration in vitro by spermatozoa preincubated with xanthine and/or xanthine oxidase. The penetration rates were, significantly (p<0.05) higher in spermatozoa preincubated without (66 and 38%) than with (40 and 15%) catalase for 0 and 30 min. When spermatozoa were preincubated and inseminated in medium with xanthine, the penetration rates were significantly higher (p<0.05) in medium with (68, 70 and 49% for 0, 30 and 60 min) than without (33, 41 and 19% for 0, 30 and 60 min) catalase. However, in oocytes were' inseminated with spermatozoa pre incubated with or without catalase in the presence of xanthine oxidase, no decrease in penetrations rates were observed for up to 60 min of preincubation. In another experiment, the penetration rates were significantly (p<0.00l) higher in medium with (75, 55 and 52%) than without (14, 4 and 8%) catalase when oocytes were inseminated with spermatozoa preincubated for 0, 30 and 60 min in the presence of xanthine plus xanthine oxidase. On the other hand, The rate of polyspermy in oocytes penetrated in medium without catalase in the presence of xanthine or xanthine plus xanthine oxidase decreased with time of spermatozoa preincubation. However, no differences were observed in polyspermy rates in the medium with xanthine oxidase alone despite presence of catalase. These results indicate the advantages of spermatozoa pre incubated with xanthine plus xanthine oxidase in the presence of catalase to increase penetration potential and with suppressed polyspermy in porcine.

Objective: To evaluate the effectiveness of soft stimulation protocol using GnRH antagonist/clomiphene citrate (CC)/recombinant FSH (rFSH) in patients undergoing controlled ovarian stimulation (COS) with intrauterine insemination (IUI), compared with GnRH antagonist multiple dose protocol (MDP) using GnRH antagonist/rFSH. Methods: Eighty infertile women were randomized to soft stimulation protocol group (n=40) or GnRH antagonist MDP group (n=40). In both groups, IUI was performed 36~40 hours after hCG injection. Statistical analysis was performed using Student's t-test, $\chi^2$ test or Fisher's exact test as appropriate. Results: Total dose and days of rFSH required for COS were significantly fewer in soft stimulation protocol group (p<0.001, p<0.001). A premature LH surge did not occur in any patients of both groups. Clinical pregnancy rate per cycle was similar between the two groups. Conclusion: Soft stimulation protocol provides comparable pregnancy rates to GnRH antagonist MDP despite fewer total dose and days of rFSH, and so can become one of the patient-friendly, cost-effective alternatives for infertile patients undergoing COS with IUI.

Numerous morphological studies on N. samarangae have been well conducted over the last ten years. In this context, we have attemtped to do molecular phylogenetic analysis by using metallothionein (MT) gene from N. samarangae. To this end, we cloned the full length cDNA of MT from cDNA library of N. samarangae. The complete cDNA sequences were obtained from the expressed sequence tag (EST) sequencing project of N. samarangae, The coding region of 195 bp gives an amino acid sequence of 65 residues including methionine. There are 5' (61 bp) and 3' (48 bp) untranslated region at both ends of the Ns-MT cDNA sequence. The combined results from BLAST analyses, multiple sequence alignment and molecular phylogenetic study of Ns-MT cDNA indicate that N. samarangae has similarity to land snails such as Helix pomatia, Helix aspersa and Arianta arbustorum.

Successful weaning is very important to provide adequate nutrients for normal growth and to induce a good diet habit. We conducted a survey on the knowledge and attitudes of women who live in Taegu toward weaning in infants, to figure out how much they know about weaning diet for the infants, which source they prefer to get the information about weaning diet, whether their knowledge affect their practice about weaning in infants, and the most effective way to educate them. A survey was conducted with the prepared questionnaire on women who responded at the residential area and market place, and those who visited Department of Pediatrics, Yeungnam University Hospital from July 25 to September 15, 1997. Statistical analysis was done with student t-test and ANOVA using SPSS program. Among total 303 responders, those who aged between 30 and 39 years were 37.2%. Scores for the six questions about weaning policy showed highest in the age group between 30 and 39 years. Higher score was recorded in the more educated group, in those who get informations about weaning diet from books, magazines and pediatricians. The majority of the responders had wrong concepts, such as feeding weaning diet using bottle(69.1%), feeding mixed with formula in the same bottle(64.5%), addition of salt(68.4%). Those who had higher educational level preferred books, magazines rather than neighbors or mother to get informations about weaning diet. Those who preferred books or magazines started weaning, stopped bottle feeding, and used spoon earlier, and their children had unbalanced diet habits less frequently. Home-made food was used most frequently, and commercial products were used less frequently. Those who were employed preferred home-made food rather than commercial products, it may be caused by the difference of the educational backgrounds from those of the unemployed. In conclusion, most responders ask neighbors and mother to get informations about weaning, and the incorrect knowledge from them could cause inadequate weaning practice and induce bad diet habit in their children. We have to find the reasons why they did not refer books or magazines frequently, and the way to resolve the problem.

The purpose of this study was to identify risk factors related to sexual function of women with coronary artery disease, and to determine the predictors of sexual function. The study design, a descriptive correlational study, was done through structural questionnaire and interview. A total of 50 subjects from C University Hospital at Kwang-ju city who have undergone coronary angiography at department of cardiology were observed and interviewed from Feb. 22, 1999 to March. 23, 1999. The number of affected vessels, the level of total serum cholesterol, and the ejection fraction of 2-D echo cardiography were analyzed to evaluate the severity of coronary artery disease. And also type A behavior pattern, health behavior, Brief Index of Sexual Functioning for Women (BISF-W) were measured. The data obtained were analyzed using percentage, mean and standard deviation, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression analysis via SPSS PC+. The results of this study were as follows: 1. The mean age of the subjects were 58.1 and 72.0% of those have been married over 30 years. Seventy two percentage were unemployed and monthly family income of 56.6% was less than 1,000,000 won (approximately $ 840). Eighty percent were in their postmenopausal state, and the frequency of sexual intercourse of 84.0% were two to three times per month. 2. The scores of type A behavior pattern were from 16 to 38(mean 24.94) and health behavior ranged from 21 to 43(mean 31.2). Abstinence from smoking, alcohol, and caffeine were best compliant factors and weight control and exercise were least abided ones. The result of 2D-ECHO EF showed that the half of the subjects were abnormal, and 24% had more than 240mg/dl of total serum cholesterol. The coronary angiography showed that 64% of the subjects had more than one affected vessels. 3. The predictors to explain the factor score of 'orgasm' were number of health examination, the pre- or post-menopausal state, protestant, number of coronary vessel affected, level of serum total cholesterol, and comorbid group of hypertension and diabetes, and it's total variance accounted for 52.4%. The predictors to explain the factor score of 'sexual activity' were comorbid group of hypertension and diabetes and type A behavior pattern, which accounted for 22.4% of total variance. The predictors to explain the factor score of 'sexual satisfaction' were type A behavior pattern, no religion, exercise, level of serum total cholesterol, and pre or post menopausal state, which accounted for 52.1%. The predictors to explain the factor score of 'sexual desire' were the period of marriage, type A behavior, employment or unemployment, and weight control, which accounted for 43.2%. The predictors to explain the factor score of 'external force of sexual functioning' were physical overload and exercise, which accounted for 41.1%. The predictors to explain the factor score of 'sexual activity' were family monthly income, catholics, and exercise, and which accounted for 35.4%. Above results lead us to some consensus that sexual function of women with coronary artery disease is related to various factors including vasogenic factors such as total serum cholesterol level, number of coronary vessel affected, an endocrinal factor such as menopausal state, and type A behavior pattern as a sociopshychological factor. And also health behaviors such as fitness care, overwork, weight control, and emotional tension are contributed to sexual function.

Sialyltransferase gene expression is altered in several cancers, including examples in the cervix. Transcriptional regulation of the responsible genes depends on different promoters. We aimed to determine the association of single-nucleotide polymorphisms in the B3 promoter of the ST3GAL4 gene and the P1 promoter of the ST6GAL1 gene with cervical premalignant lesions or cervical cancer. A blood sample and/or cervical scrapes were obtained from 104 women with normal cytology, 154 with premalignant lesions and 100 with cervical cancer. We also included 119 blood samples of random donors. The polymorphisms were identified by sequencing from PCR products. For the B3 promoter, a fragment of 506 bp (from nucleotide -408 to +98) was analyzed, and for the P1 promoter a 490 bp (-326 to +164) fragment. The polymorphism analysis showed that at SNP rs10893506, genotypes CC and CT of the ST3GAL4 B3 promoter were associated with the presence of premalignant lesions (OR=2.89; 95%CI 1.72-4.85) and cervical cancer (OR=2.23; 95%CI 1.27-3.91). We detected only one allele of each polymorphism in the ST6GAL1 P1 promoter. We did not detect any genetic variability in the P1 promoter region in our study population. Our results suggest that the rs10893506 polymorphism -22C/T may increase susceptibility to premalignant and malignant lesions of the cervix.

In various directions of cartoon, vertical stroll direction is opposite to the page direction of existing published cartoon with the popularity of webtoon and established new genre. Lots of studies on published cartoon focus on the cut direction by page, but webtoon doesn't have any concept of page. The pivot of cartoon oriented people is changed from paper to computer monitor as times go by, characteristics of media are changed and media is gradually diversified. Like the strengthening of mobile caused by smart phone's popularity, tablet PC's propagation in public education, etc. cartoon is included to the environment of media which is rapidly changed. In this situation, one of cartoon's unchanged important identities can be the direction made by harmony between picture and text. This thesis analyzed symbolic characteristics and effective value of hyogwatae, mimetic words of cartoon, focusing on works of Heo, Young Man. Hyogwatae just delivers not only sound but also shape, feeling, status, etc. and has significant characteristics by invoking the imaginary structure of literature. Strengths of modern Korean, various linguistic expressions and syllabic systems, let people feel minute feeling of language and difference of emotion and remember the memory through the direct and indirect experiences, so it makes it nuance. Because of the characteristics, representative works of Heo, Young Man have commercialization and writer characteristics, have communicated with people for a long time and have plentiful knowledge of Korean cartoon. The characteristics of hyogwatae in Heo, Young Man's cartoon make a lot of effects for the expression and delivery of cartoon more than the general expectation. When conducting the study focusing on the symbolic process of language, uncertainty and vague standard of judgement caused by the wide factors of study on the direction of general cartoon could be endured. And, through the Heo, Young Man's deep analysis on hyogwatae's direction, readers enjoy the process while inferring actually and intellectually between pictures and sentences. In the process, the equipment stimulating imagination more than pictures, effects and dialogues is hyogwatae. It's reader's equipment of active participation and its strength is symbolic structure.
