This study was carried out to select DNA markers closely linked to brown planthopper (BPH) resistance gene originated from a rice cultivar 'Cheongcheong­byeo'. For the mapping of resistant gene to BPH, a doubled-haploid (DH) population was developed by anther culture of $F_1$ plants from a cross 'Cheongcheong­byeo/Nagdongbyeo'. In BPH bioassay and marker screen­ing for the DH population, the segregation of resistant and susceptible plants to BPH fitted to a 1:1 ratio. A total of 310 RAPDs of 520 markers showed polymorphism in parental survey using 'Cheongcheongbyeo' and 'Nag­dongbyeo'. In the analysis of relationship between BPH resistance and marker pattern for 40 DH lines, the OPE16 produced a specific dominant fragment, 700 bp, which was closely linked with BPH resistance gene of 'Cheong­cheongbyeo'. Based on the linkage analysis using 7 markers, BPH resistance of 'Cheongcheongbyeo' was mapped on chromosome 12, which was closely linked with $OPE16_{700}$ at a distance of 4.6 cM.

The purpose of this study is to investigate the need of home economics education on high School male students for purpose, the questions raised in this study are as follows. 1. Does home economics education on high school male students needs\ulcorner and are whether not or home economics education on high school male students need different according to sex, age, edu-cation, income, occupation\ulcorner 2. If home economics education on high school male students need or not. What is the reason of that\ulcorner and are the reason of that different according to sex, age, education, income, occupation\ulcorner 3. If home economics education on high school male students need, what is the contents of home economics education and are that different according to sex, age, education, income, occupation\ulcorner The subjects of the study consisted of 183 men and women in Ch’ong ju City(over 21 years old) The data were analiged by statistical procedures such as frequency, X(sup)2, oneway ANOVA, two-way ANOVA, Duncan’s Multiple Range Test. The major results of the study were summarized as follow: 1. The response rate on home economics education on high school male students was absolutely high(91.8%). of demographic variables, the only sex appeared the significant differences. the men groups responsed higher not to need than the women groups. 2. As the reasons of home economics educations on high School male students needing the respons of the highest response rate were that ‘as family community, family members understant, cooperated, and are responsible with each other or one anther’and that ‘as society becomes in-dustrial gradually, family members have to have the accurate perception, or attitudies on home life’of demographic variables, sex, income, and occupation appeard the significant differences. In the contrast of that, as the reaspon of home economics education on high school male stu-dents not needing, the reasons of the highest. response rate were that ‘as sex, the role is different’and that ‘home economics education needs not essentially to learn through the school education’. and there were not differences according to demographic variables. 3. As home economics education contents for high school mal students, the most need content part was child part. the second content part was family development and family relationships part. There was the significant differences according to all the demographic variables. Particulary, the lower the lever of education, in come and occupation were, the less the degree of need on all content part was.

Physicochemical properties of freeze-dried upper and middle parts of Korean raw anther were investigated and analyzed. Moisture contents of upper part and middles part were 51.7 and 63.6%, respectively. Contents of crude protein, crude fat, crude ash, and carbohydrates of upper part of antler were 66.91, 3.52, 22.70, and 6.87%, respectively. Whereas those of middle part were 52.64, 2.50, 34.54, and 6.07, respectively. Phosphorous content was the highest in both upper (2562.0 mg%) and middle (2536.0 mg%) parts. Glycine (7597.9 mg%) and glutamic acid (5769.4 mg%) were major amino acids in upper part, glycine (9612.0 mg%) and proline (5906.3 mg%) in middle part were the major amino acids. Free sugars including fructose, glucose, sucrose, and maltose were not detected. Palmitic acid (upper part 30.83%, middle part 32.23%) was the major fatty acid in crude fat of both upper and middle parts. Vitamin A (retinol) contents of upper and middle parts were 16.40 and 12.32 IU/100 g, respectively. Vitamin C was not detected. Upper part of antler showed the highest redness (8.18), whereas middle part showed the highest lightness (71.72) and yellowness (8.13). The color difference $({\Delta}E\;27.11)$ between upper part and middle part was distinguished remarkably.

A homonym could be disambiguated by anther words in the context such as nouns, predicates used with the homonym. This paper proposes a homonym disambiguation system based on statistical semantic information which is extracted from definitions in dictionary. The semantic information consists of nouns and predicates that are used with the homonym in definitions. In order to extract accurate semantic information, definitions are used with the homonym in definitions. In order to extract accurate semantic information, definitions are classified into two types. One has hyponym-hypernym relation between title word and head word (homonym) in definition. The hyponym-hypernym relation is one level semantic hierarchy and can be extended to deeper levels in order to overcome the problem of data sparseness. The other is the case that the homonym is used in the middle of definition. The system considers nouns and predicates simultaneously to disambiguate the homonym. Nine homonyms are examined in order to determine the weight of nouns and predicates which affect accrutacy of homonym disambiguation. From experiments using training corpus(definitions in dictionary), the average accruracy of homonym disamguation is 96.11% when the weight is 0.9 and 0.1 for noun and verb respectively. And another experiment to meaure the generality of the homonym disambiguation system results in the 80.73% average accuracy to 1,796 untraining sentences from Korean Information Base I and ETRI corpus.

As a basic study on both engineering applications and representation methods of synesthesia, this paper aims at building basic system which converts a muscular sense into both visual and auditory elements. As for the building method, data of the muscular sense can be acquired through roll and pitch signals which are calculated from both three-axis acceleration sensor and the two-axis gyro sensor. The roll and pitch signals are then converted into both visual and auditory information as outputs. The roll signals are converted into both intensity elements of the HSI color model and octaves as one of auditory elements. In addition, the pitch signals are converted into both hue elements of the HSI color model and scales as another one of auditory elements. Each of the extracted elements of the HSI color model is converted into each of the three elements of the RGB color model respectively, so that the real-time output color signals can be obtained. Octaves and scales are also converted and synthesized into MIDI signals, so that the real-time sound signals can be obtained as anther one of output signals. In experiments, the results revealed that normal color and sound output signals were successfully obtained from roll and pitch values that represent muscular senses or physical movements, depending on the conversion relationship based on the similarity between color and sound.

This experiment was carried out to investigate the fertilization and the size of mature female and male gametophytic parts of Pulsatilla koreana after artificial pollination. The size of pollen is $26.5{\mu}m$ at the time of anther dehiscence, that is, about $3{\sim}4$ days after pollination. Synergid nucleus, egg nucleus, and polar nucleus are 10.0, 15.0, and $32.5{\mu}m$ respectively at the time of completing egg apparatus formation, that is, about 2 days after pollination. Poller tubes germinate on stigma about 10 hours, passing lower part of style about 30 hours, penetrating into micropyle about 35 hours after pollination. Sperm nucleus penetrates into polar nucleus about 40 hours and egg cell about 48 hours after pollination. But, there seems to be different among the individuals. Multinuclei and multinucleoli are formed in egg cell, synergid, and polar nucleus about the time of fertilization. Proembryo is formed about 4 days, being changed to large globular form about $6{\sim}8$ days after pollination. Endosperm nuclei divide into free nuclei after fertilization and change to cotyledon in gymnosperm. There seems to be same phenomena in Pulsatilla koreana.

Many flowering plants possess genetically controlled self -incompatibility (SI) system that prevents inbreeding and promotes outcrosses. SI is usually controlled by a single, multiallelic S-locus. In gametophytically controlled system, SI results when the S-allele of the pollen is matched by one of the two S-alleles in the style, while in the sporophytic system self-incompatible reaction occurs by the interaction between the pistil genotype and genotype of, not the pollen, but the pollen parent In the former system the self-incompatible phenotype of pollen is determined by the haploid genome of the pollen itself but in the latter the pollen phenotype is governed by the genotype of the pollen parent along with the occurrence of either to-dominant or dominant/recessive allelic interactions. In the sporophytic type the inhibition reaction occurs within minutes following pollen-stigma contact, the incompatible pollen grains usually failing to germinate, whereas in gametophytic system pollen tube inhibition takes place during growth in the transmitting tissue of the style. Recognition and rejection of self pollen are the result of interaction between the S-locus protein in the pistil and the pollen protein. In the gametophytic SI the S-associated glycoprotein which is similar to the fungal ribonuclease in structure and function are localized at the intercellular matrix in the transmitting tissue of the style, with the highest concentration in the collar of the stigma, while in the sporophytic SI deposit of abundant S-locus specific glycoprotein (SLSG).is detected in the cell wall of stigmatic papillae of the open flowers. In the gametophytic system S-gene is expressed mostly at the stigmatic collar the upper third of the style length and in the pollen after meiosis. On the other hand, in the sporophytic SI S-glycoprotein gene is expressed in the papillar cells of the stigma as well as in e sporophytic tape is cells of anther wall. Recognition and rejection of self pollen in the gametophytic type is the reaction between the ribonuclease in the transmitting tissue of the style and the protein in the cytoplasm of pollen tube, whereas in the sporophytic system the inhibition of selfed pollen is caused by the interaction between the Sycoprotein in the wall of stigmatic papillar cell and the tapetum-origin protein deposited on the outer wall of the pollen grain. The claim that the S-allele-associated proteins are involved in recognition and rejection of self pollen has been made merely based on indirect evidence. Recently it has been verified that inhibition of synthesis of S$_3$ protein in Petunia inflata plants of S$_2$S$_3$ genotype by the antisense S$_3$ gene resulted in failure of the transgenic plant to reject S$_3$ pollen and that expression of the transgenic encoding S$_3$ protein in the S$_1$S$_2$ genotype confers on the transgenic plant the ability to reject S$_3$ pollen. These finding Provide direct evidence that S-proteins control the s elf-incompatibility behavior of the pistil.

The effect of the addition of the fresh medium, volume of under solid medium in double layer culture as well as the medium change after pretreating microspores on the production of embryos in microspore culture of hot pepper (Capsicum annuum L.) has been studied. When cultured after heat pre-treatment, changing pretreatment media with fresh culture media proved to be more effective for embryo production rather than supplementing additional culture media. Heat-pretreating for 3 days turned out more effective for embryo production than pretreating for 1 or 2 days. In the case of anther pretreatment, the addition of fresh medium after culture was not effective for embryo production. In pretreating microspores, however, supplementing additional fresh culture media greatly improved embryo yield and quality. The best time point of media addition was 4 days after culture commenced, and the most effective number of times of media addition was one time addition. Moreover, the effective volume of added medium in double layer culture for embryo production was 1.5 ml. The addition of media more than 1.5 ml reduced both embryo yield and quality. Double layer medium was more effective for embryo development than liquid medium. When the volume of under solid medium increased ranging from 3 ml to 7 ml, more cotyledonary embryos were produced in either 5 ml or 7 ml compared to 3 ml, even though the total number of embryos were highest in 3 ml. These results can be used as an important data for establishing an efficient microspore culture system for producing high frequency of normal embryos in hot pepper.

This study was conducted to develop a japonica-type rice cultivar with brown planthopper (BPH) resistance using DNA markers. A doubled haploid (DH) population consisting of 120 pure-lines was established by anther culture of $F_1$ hybrids between 'Samgang', a Tongil type BPH resistance cultivar, and 'Nagdong', a japonica cultivar. To determine the map position of genes responsible for BPH resistance in rice, a genetic map was constructed based on 120 DH lines. A total of 162 molecular markers were classified into 12 linkage groups, covering 1,884 Kosami centimorgan (cM) with an average of 11.6 cM. Five QTLs (qBPR3, qBPR6, qBPR7, qBPR8, and qBPR12) associated with BPH resistance were identified and mapped on chromosomes 3, 6, 7, 8, and 12, respectively, using the genetic map constructed in this study. To analyze the relationship between BPH resistance and agronomic traits, a total of eight QTLs related to the agronomic traits were detected on 12 rice chromosomes. In an analysis of relationships, three QTLs (qBPR3, qBPR7, and qBPR8) showed a linkage with tested agronomic traits. A QTL (qBPR3) located on chromosome 3 (RM282-3023) was closely linked to culm length (qCL3). The QTL (qBPR8) for BPH resistance on the short arm of chromosome 8 also overlapped the region detected in culm length (qCL8).

Andong is the place where the most ginger is produced in Korea. The article is based on a study on the development of storytelling of a co-brand of local agricultural products, focusing on the case of 'The Geudae Ginger,' a co-brand of ginger in Andong. This study aims to develop a brand storytelling of Andong Ginger's co-branded 'Geudae Ginger' to build an image as a local specialty and help revitalize the Andong ginger's industry. The process of developing storytelling to activate 'Geudae Ginger' brand is as follows. In the first step, I collected storytelling materials through data research. Ginger, which has long been used as a medicine for mankind, has more historical and cultural stories than anything else. In the second step, story resources were extracted based on data research. By analyzing the story properties of Andong ginger, we made its list. As a result, the image of the nobility, rigidity and chastity of ginger, which is used to benefit all over, could be associated with the image of Andong, the capital of Korean spiritual culture. Storytelling was developed in the third step. The main theme was 'Andong ginger with anther level ' and the main story was 'The Story of Andong's Ginger Teacher'. The scenario developed is as follows: 1. Introducing Andong's Ginger Teacher, 2. The birth of Dosan Thirteen Tea, 3. 'Geudae Ginger' that bridges love. In the last fourth step, I proposed ways to utilize storytelling. I presented the spread methods of consumer-participated storytelling using images of 'Geudae Ginger' and a new-tro event with teachers highlighting the image of 'Ginger Teacher' and others as a local business program for storytelling expansion.
