Studies on menstruation have focused only on menstruation itself and menstrual disorders. The menstruating girls or women have been neglected. So, the purpose of this study was to understand menstrual experience of adolescent girls in their perspective and build a theory on it, The specific purpose of this study were to find initial reaction of the girls, their strategies to adapt to menstruation. consequences of their efforts, influencing factor, and patterns of experience. The subjects of this study were eleven adolescent girls who experienced menarche three months to twenty-six months before the interview time. They were selected purposively. Their ages were in range of twelve and sixteen. One of them was a elementary school girl, three high school girls, and seven middle school girls. Two girls were handicapped because of cerebral palsy. All of them had some knowledge about menstrual physiology and hygiene during menstruation. Data were collected from September, 1994 to July, 1995. Data collection ＆ analysis were done according to the grounded theory methodology by Strauss ＆ Corbin(1990). Data collecting method was the long interviews and observation. Each interview took from 1 hour to 2 hours. Interview were tape-recorded and transcribed later by author. Data were analyzed immediately after interviews. Based on the results of previous interview, next interview were planned until gathered data reached the saturation point. Results were as follows. One hundred and six concepts were found. Those concepts were grouped into twenty eight categories and then fourteen higher categories. Twenty eight categories were as follows. “want to hide”, “bewildered”, “sense of burden”, “sense of heterogeneity”. “gladness”. “sense of superiority”, “negative empathy”, “positive empathy”, “limited hygenic control”, “sense of timing”, “lack of knowledge”, “lack of support”, “advance knowledge”, “informational support”, “emotional support”, “endurance”, “prayer”, “disclosing”, “avoidance”, “diversion”, “sense of powerlessness”, “discovery of sex identity”, “sense of maturation”, “sense of stability”, “acceptance of menstruation ”. fourteen higher categories were as follows. “negative feeling”, “posive feeling”, “exchange of feeling”, “limited hygenic control”, “sense of timing”, “accumulated experience”, “dysmenorrhea”, “level of knowledge”, “need for support”, “perceived support”, “sharing of feeling”, “self-control”, “passive acceptance”, “active acceptance”. The core category was “emotional shaking”, which consisted of “positive feeling” and “negative feeling”. “Emotional shaking”comes up to every adolescent girls experiencing menarche, independently of any contextual conditions, and its dimension has two directions : positive one and negative one. Its influencing factors were time of menarche, advance knowledge, support from the significant persons, expression and self-regulation. Even if they showed different process of adaptation to menstruation, general process of adaptation were as follows : 1. stage of emotional shaking 2. stage of acceptance 3. stage of internalization of the menstrual experience. Seven patterns existed on the process of adaptation to menstruation after menarche. Those are as follows. 1. If girls thought their menarche came too early and they had not much knowledge on menstruation, they had a kind of negative feeling. If they did not get enough support and dysmenorrhea superimposed, they came to accept menstruation passively. 2. If girls had menarche too early. they had negative feeling, even though they had enough advance knowledge. But support helped them accept menstruation easily. 3. If girls had menarche too early, they had negative feeling, even though they had enough advance knowledge on menstruation. But by experiencing subsequent menstruations and disclosing feeling, they began to accept menstruation. 4. If girls had menarche too lately and they had enough advance knowledge on menstruation. they had positive feeling. If dysmenorrhea superimposed later, their feeling turned in to negative one. But they came to accept menstruation positively by disclosing feeling and getting support. 5. If girls had menarche too early, they had negative feeling, even though they had enough advance knowledge on menstruation. In addition to this. if dysmenorrhes superimposed while they did not get enough support, they felt powerless and came to accept menstruation passively. 6. If girls had menarche too early and did not get enough advance knowledge, they had negative feeling. But disclosing feeling and support made them get sense of homogeneity and began to accept menstruation. 7. If girls had handicap, they had negative feeling, even though they had enough advance knowledge and menarche was late. But Menarche made them get feel sexual identity. Their limited hygenic control and negative empathy from their mothers made them accept menstruation passively. To let adolescent girls take their menstrual experience as a part of their lives forming a positive sense of feminine identity, it needs qualified teaching and, support and deep concern of the significant others. Nurses including school nurses should try to develop an educational program, which include menstrual physiology. hygiene during menstrual period, meaning of menstruation and impact of menstruation on the development of female sexual identity.

This study was carried out to obtain conjugated linoleic acid (CLA) producing lactic acid bacteria for further study on the enzymes related to the production of CLA which has gained considerable attention and on the development as a probiotic culture. Total 34 lactic acid bacteria were isolated from 19 feces samples of healthy babies. CLA forming ability was measured spectrophotometrically by the modification of linoleate 12-cis, 11-trans-isomerase activity measuring method, and CLA of the cultures were extracted, methylated, and examined by HPLC analysis. CLA methyl ester of only one culture showing the highest value of CLA forming ability could be detected by HPLC analysis. The culture was found to be Gram positive, rods and catalase negative. It grows at $45^{\circ}C$ but not at $15^{\circ}C$, and was identified to be Lactobacillus fermentum on the basis of the biochemical characteristics and the utilization of substrates. These results provide an efficient experimental method to screen CLA producing lactic acid bacteria.

Consumers experience various cognitive and emotional contents of clothing through postpurchase process. These experiences may affect consumer satisfaction as well as brand attitude toward clothing products. The purpose of this study was to examine the effects of consumption experiences on the brand attitude toward clothing products. The research questions for accomplishing the purpose of this study were to investigate 1) the dimension of consumption experiences, 2) relationships among consumption experience, satisfaction and brand attitude toward clothing. The sample of this study was consisted of 431 females. The survey method, and factor analysis and regression were utilized for this study. The results were as follows; First, it was found out the consumption was composed of two dimensions such as cognitive and emotional experiences. According to the result of factor analysis, the cognitive experiences through consumption process were composed of 6 factors, that is, the suitability, fitness, utility/economy, sewing, deformation, and management. And emotional experiences were composed of 5 factors, that is, unpleasure, activeycomfort, inter-oriented pleasure, extra- oriented pleasure, tension. Also emotional experiences could be composed of two dimensions, that is, positive and negative emotion. The positive emotions were included pleasure and active/comfort. The negative emotions were included unpleasure and tension. Second, the result of path analysis showed that consumption experiences were related to satisfaction and brand attitude. A satisfaction influenced on brand attitude more strongly than others. And sewing, activejcomfort, extra-oriented pleasure out of cognitive and emotional experience factors affected to brand attitude directly. Satisfaction was also influenced by cognitive and emotional factors, and was the important mediator in forming brand attitude toward clothing through consumption experience. Above results imply that consumer experience multidimensional cognitive and emotional aspects of clothing through consumption process. The cognitive and emotional aspects consisting of consumption experiences, satisfaction, and brand attitude are interrelated causally. Therefore, experience related variables could be the antecedents of satisfaction and brand attitude. The satisfaction and positive emotion could be also important factors in brand attitude toward clothing.

This study investigated the effect of emotional appeals on consumers' attitude towards fair trade apparel advertisements, and their intention to purchase those fair trade apparels. The interaction effect of the advertising channel and the mediation effect of perceived consumer effectiveness(PCE) were examined. Four stimuli were manipulated using two types of emotions(positive/negative) and two types of advertising channels(magazine/SNS) were used to analyze consumers' reaction. The results demonstrated the significant differences in attitude towards ads and purchase intention according to the types of emotional appeals used in fair trade apparel ads. However, the interaction effect between the types of emotion and advertising channels was not identified. The results of mediation analysis showed that positive emotion influenced purchase intention directly without forming a favorable attitude towards the ads, whereas negative emotion had no significant influence on attitude towards the ads and purchase intention. The results also identified that PCE mediated between emotion elicited by ads and purchase intention. This study suggests that delivering images and messages that creates positive emotion should be considered when fair trade ads are produced. In addition, fair trade ads need to be devised to enhance PCE by emphasizing that ethical choices of individual consumers can change the working environment of manufacturing countries.

Protein and gene detection have been growing importance in medical diagnostics. Field effect transistor (FET) - type biosensors have many advantages such as miniaturization, standardization, and mass-production. In this work, we have fabricated metal-oxide-semiconductor (MOS) FET that operates as molecular recognitions based electronic sensor. Measurements were taken with the devices under phosphate buffered saline solution. The drain current ($I_{D}$) was decreased after forming self-assembled mono-layers (SAMs) used to capture the protein, which resulted from the negative charges of SAMs, and increased after forming protein by 11.5% at $V_{G}$ = 0 V due to the positive charges of protein.

The aim of this study is having the status, knowledge and attitude of the high school attendees toward smoking be analyzed, helping to make effective health education methods to diminish adolescent smoking habits. The field self-questionnaire investigation has been performed from Oct 10th through 23rd in 1999. The whole 427 cases were distributed to 1st and 2nd grade students of randomly selected men's high school in Seoul. And 414 cases (97%) were finally selected for analysis after exclusion of cases with insufficient information. The main contents of questionnaire are composed of several sectors; the general characteristics of the interviewees, the relationship with parents, the life style and the peer relationship in school. And smoking-related characteristics are taken into consideration, too. The major findings of the study are as follows: The smoking/non-smoking related factors are, in socio-demographical terms, the grade, average spending per month of the interviewees. And the degree of satisfactory relationship with parents is significant on smoking behavior. The higher, the degree of satisfaction on school life and relationship with designated teacher, the more chances of non-smoking habit. Poor academic grades and peer group dependability of interviewees cause higher smoking habit rate in other way. The self-interviewees grade and cohabitation with parents are also significant on both the attitude toward smoking habit and the knowledge on smoking statistically. The academic history and vocations of the parents and the academic grades of interviewees are also effective variables, but don't make any gap between groups knowledge on smoking. Smoking groups used to have positive attitude toward smoking habit. Both the attitude and knowledge on smoking by the consideration of Quit-smoking have statistically significance. The groups which have negative attitude and high knowledge on smoking quit-smoking into consideration. And the primary cause of quit-smoking is on health by smoking. Depression, stress, adult smoking in the house, peer group pressure, cigarettes advertisements on papers and magazines and smoking scenes on TV have positive correlation on forming smoking habit (p〈0.001) But the knowledge on diseases triggered by smoking has negative correlation on forming smoking habit. (p〈0.05, p〈0.001). Social factors as monthly spending, relationship and communication with parents, the degree of satisfaction in school life, academic grades and student-teacher relationship have crucial negative correlation on smoking habit. That is to say, the higher, the monthly spending is, the worse, the relationship with parents and teachers is, the lower, the academic grades of the student is, the percentage of the interviewees who have smoking habit seems to get higher.

Two intraocular tumors were identified in low and medium dosed groups of a carcinogenicity study using 200 males and 200 females Sprague-Dawley rats in Screening & Toxicology Research Center, Korea Research Institute of Chemical Technology. The tumors were grossly observed as white or yellow, unilateral nodules. They were approximately $1-2{\times}3-5mm$ in size. The tumors located in the region of iris and/or ciliary body invaded peripheral cornea. The microscopic features were usually composed of spindle cells arranged in parallel, forming gently curving bundles or whorls. The spindle cells had poorly defined cell boundaries, scant to moderate cytoplasm, fusiform nuclei and indistinct nucleoli. Mitotic figures were rare and areas of necrosis were present. The spindle cells had positive immunoreactivity for S-100 protein and vimentin but negative for desmin, collagen and HMB-45 antibody. In special histochemical studies, the spindle cells react with Gomori's stain for argyrophih fibers, Prussian blue stain for iron but negative with Masson-Fontana's stain for melanin granules. Ultrastructurally, cytoplasmic premelanosomes were not observed in the tumor cells due to the poor preservation of tumor masses. Based on the results, the tumors were diagnosed as amelanotic melanoma.

The antimicrobial substance produced by Lactobacillus bulgaricus was inactivated by pretense, which confirmed it as a bacteriocin and referred to 'bulgaricin HJ'. The bulgaricin HJ showed the inhibitory activity against mastitis pathogens, gram-positive and gram-negative bacteria. The optimal conditions for the production of bulgaricin HJ were at the temperature of $30^{\circ}C$ and 10 h after cultivation of L. bulgaricus. Staph. and Strep. agalactiae, common bovine mastitis pathogens, were treated with bulgaricin HJ by the agar well diffusion method and showed antimirobial activities to the bovine mastitis pathogens. The activity of the bulgaricin HJ was maintained at pH 6-7 and $100^{\circ}C$ for 60 min against the mastitis pathogens. The bulgaricin HJ was determined as class IV bacteriocin by various enzyme treatments. Colony forming units analysis with indicator strains by the treatments of bulgaricin HJ indicates that the mode of bacteriocin action was bactericidal rather than bacteriostatic.

We prepared hybrids between layered double hydroxide (LDH) and natural plant extract such as Peaonia suffruticosa Andrews (PS) and Peaonia Japonica (PJ) which was confirmed anti-bacterial activity through paper disc diffusion assay. According to X-ray diffractometer, scanning electron microscope, zeta-potential measurement and quantification of extract loading amount in hybrids, we confirmed that similar amount of PS and PJ loaded on inter-particle pore of LDH with partial adsorption on surface of LDH through reconstruction process. We also evaluated the bacterial colony forming inhibition of PS extract, PJ extract, PS-LDH and PJ-LDH hybrids against Escherichia coli as gram negative bacterium and Bacillus subtilis as gram positive bacterium, suggesting that both hybrids have enhanced anti-bacterial activity compared with extract itself.
