Gamadi, a native rice cultivar from Nepal in which the panicle remains enclosed within its flag leaf sheath upto maturity, was crossed with different genetic marker testers of 12 linkage groups in order to analyze its linkage relationship. The results obtained from the experiment were summarized as follows: Normal segregations of all the genetic marker genes used in this experiment viz Cl, wx and Pla of linkage group I, Pn, Rd and Pub of linkage group III, and lg, g, Ps, gh, Hla, la, nl, bl, be and gl of linkage groups II, IV, V, VI, VII, VIII, IX, X, XI, and XII respectively confirmed the previous results, and also strongly indicated that the genetic constituent of the Gamadi and marker testers is same. 'Gamadiness' (the panicle enclosing character) was controlled by two complementary dominant genes with the segregation ratio of 9 Gamadi to 7 normal panicle-exserting types. These genes have been temporarily proposed as G-a and G-b for gamadiness. G-a gene was found to be linked with the neckleaf gene (nl) of linkage group Ⅸ with the crossover value of 0.3733$\pm$0.027. G-b gene appeared to be associated with the brittle culm gene (bc) of the linkage group XI with the crossover value of 0.2725$\pm$0.061.TEX>0.061.

The purpose of this study is to explore the aesthetic characteristics of outerization phenomenon of contemporary fashion. Outerization, transforming underwear as outerwear, is one of the most dominant and widespread fashion trends in the dawning of new millenium. Fashion always exists for living body and tributes to express idealized beauty of human body and aesthetics of the era. If so, exploring the formative expressions and aesthetic characteristics of outerization would be an meaningful guideline to deduce changed relationship between fashion and body of the 21st century. The methodology of this study is to research of fashion collections such as Paris, Milan and New York which were held the first decade of new millenium, from 2000 Spring/Summer to 2009 Spring/Summer. The styles expressing outerization were selected and assorted based on the main formative expression. Then the aesthetic characteristics were classified. The way of expression of outerization is categorized into 4 parts ; Transition, Exposure, Transparency, and Deconstruction. Aesthetic Characters of outerization is classified 4 assortments as well ; Eroticism, Fun with parody and kitch, cyber culture, Gender politics, and Power fetish. Eroticism is the most clearly identified one. Coming out of underwear imply naked body itself, so it has erotic appeal. Fun is the second character. A pleasant sensation from the outerization of undergarments maximizes a disposition of play from parody, kitch, and cyber culture. The third is Gender Politics and it introspects how the society consumes woman body in history and modern times. Power Fetish, the last one, speaks for the female body with changed vision for femininity underneath the sphere of influence of feminism and post modernism, then emphasizes the subjectivity and independence of woman. From the research above, this study will help to understand the overwhelming outerization phenomenon and contribute to expansion of the horizon of the study of fashion aesthetics. It will serve fashion creative source through various outerization cases as well.

Optical disk drive device is improved in rotating speed for faster data reading. In the case of CD-ROM, rotating speed is over 10000 rpm in the practical use. As a result of high rotating speed, unexpected effects as like increasing disk fluctuation and acoustic noise are raised by the air friction on the rotating disk and the eccentricity of rotating parts. The overall acoustic noise of running CD-ROM could be classified into two different characterized noise. The first is the structural-borne noise which is generated from vibrating solid body. By the reason, the signal of structural borne noise has very similar to the signal of surface vibrating one. It has dense noise energy at specific frequency region. The other is the air-borne noise which is generated from turbulence or vortex caused by friction between disk and air. The signal of air-borne noise has no dominant peak point at acoustic pressure-frequency domain. The noise energy is widely distributed while comparatively high and large frequency region. The structural-borne noise could be reduced by reducing vibration of structure and in addition it's target reducing frequency is narrow. However the air-borne noise reduction is effectively needed of enclosing method for the noise source located near the disk surface because it is difficult to define target frequency point. In this study, the acoustic noise at driving CD-ROM is classified by the sides of it's character and tried to reduce the overall acoustic noise.

Winter cereals are acclimated during wintering, and thereafter their freezing resistance is increased. In order to analyze inheritance and heritabilities for photoinhibition of photosynthesis by high light intensity under low temperature, and to evaluate the relationship between low temperature-induced photoinhibition and winter survival, 4 parental half diallel crosses were used. The detached leaves of 7-8cm long from plants grown for 35 and 55 days were placed on wet filter paper and placed in trays at 5$^{\circ}C$ cold room with 1,200 $\mu$mol $m^{-2}$ $s^{-1}$ PPFD. Chlorophyll fluorescence was measured with a chlorophyll fluorescence system after dark adaptation for 30 min. The Fv/Fm of 35day old plants was reduced from 0.714 in the control leaves to 0.409 and 0.368 following photoinhibitory treatment of 6h and 8h and the CVs were increased from 0.8% to 22.2-22.3%. The Fv/Fm of 55-day old plants was reduced from 0.775 in the control leaves to 0.485 and 0.439 following photoinhibitory treatment of 10h and 12h, respectively. According to half diallel cross analysis, Reno and Dongbori 1 (highly resistant to photoinhibition) was dominant, but Oweolbori (susceptible to photoinhibition) was recessive, and photoinhibition showed partial dominance with highly additive gene action. Dongbori 1 showed the greatest GCA effects for photoinhibition, and GCA/SCA ratios (8.7-22.3 times) indicated that the additive variance for the character was more important. Winter survival in barley crosses was positively correlated with resistance to photoinhibition and significantly fitted by linear regression ($R^2$=0.751$^{**}$-0.779$^{**}$). The chlorophyll fluorescence measured by Fv/Fm has been found to be highly inheritable and very useful in evaluating relative levels of freezing resistance in barley.ley.

Current data on reproductive characters of endemic and native species are essential to provide a strategy for the conservation of these species. Red pine (Pinus densiflora Sieb. & Zucc.) is one of the dominant, native tree species in Korea, but its reproductive ecology is not well-known. In 1997, the pattern of variation in cone and seed yields contributing to the conservation of declining populations of red pines was examined. Plant height and dbh were measured, and several new cones were collected from each tagged tree after counting the number of cones on each tree. For a subset of cones sampled, the number of fertile scales, the number of seeds at three development stages (early/late aborted, and filled seed), seed wing size, wing color, and individual filled seed mass were measured. The three sites which differed significantly in mean plant size also differed in mean cone and seed production per plant. However further analyses showed that most variation in characters examined occurred among plants within sites, but not among sites. An average of 90% of the potential seeds on the cones aborted at an early developmental stage, demonstrating that early abortion is a major factor affecting the number of filled seeds per cone. Individual seed mass was the only character which exhibited significant variations among sites as well as among trees within sites. Individual seed mass was overall negatively correlated with both the percentage of late abortion and the number of old cones per plant, suggesting that both the past and current years' reproductive activities have caused variations in seed mass. The potential dispersal distance of red pine seeds is quite large. However, wing loading was correlated with seed mass and number in a complex pattern across the sites. Distribution of seeds with varied colored wings differed among sites and among trees within sites. These results suggest that red pines at different sites might possess different strategies to cope with selection pressures acting during the final phase of reproduction, from seed dispersal to establishment. Then the ‘fitted’ red pine trees at each site should be identified and managed to conserve or restore populations.

We have analyzed the time series of Ca II H,K and ${\lambda}8498$ line profiles taken for a sunspot (SPO 5007) with the Echelle spectrograph attached to Vacuum Tower Telescope at Sacramento Peak Solar Observatory. Each set of spectra was taken simultaneously for 20 minutes at a time interval of 30 seconds. A total of 40 photographic films for each line was scanned by a PDS at Korea Astronomy Observatory. The central peak intensity of Ca II H ($I_{max}$), the intensity measured at ${\Delta}{\lambda}=-0.1{\AA}$ from the line center of ${\lambda}8498(I_{{\lambda}8489})$, the radial velocity ($V_r$) and the Doppler width (${\Delta}{\lambda}_D$) estimated from Ca II H have been measured to study the dynamical behaviors of the sunspot chromosphere. Fourier analysis has been carried out for these measured quantities. Our main results are as follows: (1) We have confirmed the 3-minute oscillation being dominant throughout the umbra. The period of oscillations jumps from 180 sec in the umbra to 500 to 1000 sec in the penumbra. (2) The nonlinear character of the umbral oscillation is noted from the observed sawtooth shaped radial velocity fluctuations with amplitudes reaching up to $5{\sim}6\;km/sec$. (3) The spatial distribution of the maximum powers shows that the power of oscillations is stronger in the umbra than in the penumbra. (4) The spatial distributions of the time averaged < $I_{max}$ > and < $V_r$ > across the spot are found to be nearly axially symmetric, implying that the physical quantities derived from the line profiles of Ca II H and ${\lambda}8498$ are inherently associated with the geometry of the magnetic field distribution of the spot. (5) The central peaks of the CaII H emission core lead the upward motions of the umbral atmosphere by $90^{\circ}$, while no phase delay is found in intensities between $I_{max}$ and $I_{{\lambda}8498}$, suggesting that the umbral oscillation is of standing waves.

Gender role identity is a key subject toward adaptation in later life. In this paper, we tried to understand the specific types and characteristics of gender role identity in view of older men. The research collected and examined 40 representative descriptions representing gender role identity, including 20 for masculinity and 20 for femininity from 40 older men. We obtained four types of gender role identity of older men from this research. "Powerful-expressive type" is energetic and reveals his brave and dominant tendency when they are working. "Powerful-taciturn type" is strongly independent and has a firm conviction, but they do not express those characters and remain silent. "Powerful-paternal type" handles his work with a driving force, and has a tender character. "Paternal-caring type" finds his own worth in life by caring for his family and children, and considers others more than himself. Future research is needed to verify how the types of gender role identity are linked to psychosocial adaptive aspects, health behaviors, mental and physical health.

This study provides basic research for developing dress forms of women's wear making. This study compared the average body size of Korean women by investigating the shape, composition and size of 417 dress forms for pattern making, sold at Korean and international online malls. The results showed that Korean brands produced torso-type and torso-crotch-type (94.13%), torso-type was the most dominant type made by Japanese Ki and French St (${\geq}80%$), and all US Al products were whole-body-type. The most common used internal filler of the dress forms was urethane for South Korean companies and paper for Japanese Ki and French St. In most cases, cotton was used for outer materials. Alternatively, linen and rayon were used as outer materials. Al did not indicate the materials used for filler and outer layers. Additionally, the sizing system of dress forms was commonly presented as a Numeric type. In addition to Numeric type, Ki presented body type + usage and Al used character type. When the dress form size for the average bust size of each age group was evaluated, waist measurements were smaller than the corresponding bust measurements. Dress form was presented in the KS interval and was compared with the $mean{\pm}1{\sigma}$ interval of each age group. The majority of the dress forms produced in South Korea were for body shapes in their 20s.

Incontinentia pigmenti(IP), or Block-Sulzberger syndrome is a rare X-linked dominant genodermatosis that affects almost in female infant and is usually lethal for males in utero. IP is characterized by four cutaneous stages and is frequently associated with dental, ocular, central nervous system and structural anomalies. Dental problems are congenital missing of teeth, delayed eruption, abnormal crown shape. We reported a case of 5 year-old female with IP. She had congenital missing of multiple primary and permanent teeth, accessory cusp and cone-shaped crowns. Systemically, she had a problem of retina and hyperpigmented macules on her trunk and extremities as typical character of IP. As the syndrome involves many different medical problems and needs comprehensive consideration. Dental care should be performed in a multidisciplinary consultation system.

This study confirmed the followings based on analysis of language messages in 718 advertisement in , AMOREPACIFIC's beauty magazine, published from 1958 to 2018 by product categories, era, in terms of purchase information, persuasive expression, word type. First, the number of pieces among 1980s to 1990s advertisement were the largest and, in terms of product categories, there were the greatest number of pieces in skincare, makeup and mens products. Second, headline and bodycopy had a different aspect in persuasive expression. "focused on image-making" was mainly used for head lines. Specifically, "situational image" was generally dominant. While the "user image" was higher before 1990's, "brand image" was as recent times. "Informal" was mostly applied for bodycopies, especially, "general information" and "differentiated information" was used the most. It is important to know what kind of information the brand established in each brand should be embodied rather than simply dividing the appeal method into "rational appeal" and "emotional appeal."Third, persuasive expression has different aspects in headlines and body copies. "focused on image-making" was mainly used as headlines. Specifically, "situational image" is dominant. Also, "user image" was high before 1990s but "brand image" got higher in recent times. "Informal" was mostly used as body copies, especially "general information" and "differentiated information" were the most frequently selected. Therefore, it is important to apprehend which information to specify established images by brands, rather than to divide "rational appeals" and "emotional appeals". Lastly, categorizing word type into brand names and headlines, foreign language was the most dominant in brand names and Chinese characters in headline. Remarkably, brand names in native language temporarily high in 70's and 80's, which could be interpreted to be resulted from the government policy promoting native language brands in those times. In addition, foreign language was frequently used in cosmetics and Chinese characters in men's product. It could be explained that colors or seasons in cosmetic products were expressed in foreign language in most case. On the other hand, the inclination of men's product consumers, where they pursue prestige or confidence in Chinese character, was actively reflected to language messages.
