Identification of compatible parental line is of great importance in introduction of useful characters to onion breeding program, beyond the severe hybridization barrier. Phylogenic analysis of Allium section Cepa was conducted through PCR by URPs, repeated sequences of A. fistulosum, and microsatellite markers. Totally 76 accessions originated from 21 countries were clustered into five groups at a 0.84-similarity level: group I;A. cepa and its wild relatives and A. cepa ssp. ascalonicum, group II; A. cepa ssp. wakegii, A. cepa ssp. proliferum and Samcheung-pa group III; A. fistulosum and A. altaicum, group IV; A. galanthum, group V; Soeckkori-pa. Samcheung-pa and Soekkori-pa, Korean local varieties, shared band type of both Cepa group and Altaicum group, indicating that those are derived from interspecific hybridization between A. fistulosum and A. cepa.

Internally Korean insurance market is that whole life products' growth are becoming slowdown that's why new insurance products have appeared on the market in consideration of consumer's needs recently. Externally domestic insurance market competitions has drifted from insurance industry to whole financial industry since bankasurance started. Life insurance companies should open up a new market to survive from severe competitions. Worksite marketing can be an alternative. An insurer make arrangements with an employer about an insurance terms which an insurer offers in Worksite marketing. Then eligible individuals enroll in the plans at their own discretion and pay 100 percent of the premium for coverage through payroll deductions. An employer doesn't need to pay extra money for additional benefit but can raise employee's loyalty and satisfaction of company through worksite marketing. An employee can be covered at discounted premium rate and less strict underwriting guidelines to an insurer compared to individual insurance. In developed countries specially U.S insurance market, Worksite marketing is getting very popular and growing rapidly due to the advantages. Worksite marketing has both individual insurance characters and group insurance characters. Individual insurance characters are that employees enroll in the plans at their own discretion and pay 100 percent of the premium for coverage. Group insurance characters are that actively at work and participation etc. An insurer have to reflect these two characters on Worksite marketing when an insurance company work out a plan for developing products and underwriting guidelines. When an insurer devise worksite products, one should consider participation level which means percentage of eligible employees participating. Participation is related to anti-selection. As we know underwriting is essential for every kind of insurance, especially underwriting plays major role in worksite marketing. We can see that in the below. Firstly, it has a function in calculation of premium rate. When calculate premium rate for worksite products underwriters have to estimate expected participation level and risk factors. So underwriters and acturies keep in close contact with each other. Secondly, underwriting methods are important. When an insurer underwrite worksite products, there are three kinds of underwriting methods. These are Simplified issue underwriting, Full underwriting and Guaranteed issue underwriting. Simplified issue underwriting typically requires no medical examination, but usually requires supplying satisfactory answers to one or several health and/or lifestyle questions. Full underwriting requires a complete medical history questionnaire that may further require an exam. Guaranteed issue underwriting means that coverage is issued without the employee having to provide evidence of insurability. When insurer set the GI limit are usually based on the type of industry, number of eligible employees, the average amount of coverage and participation level. In addition to insurer should have a clear definition of eligible employee on the insurance provision and application form. It will minimize possibility of trouble claims and anti-selection. An insurer also establish preexisting condition exclusion and special guidelines for late entrants. When an insurer introduce Worksite marketing to Korean insurance market, an insurer has to examine market research to analyze potential market and strategy of sales most of all. Also an insurer should review real situation of the U.S, England and Japanese market etc. There are a lot of new technologies about worksite marketing process that an insurer should learn. When an insurer consider many things which we explained it can be a real alternative.

This study was conducted to evaluate the growth characters and yield components of 18 collected sesame cultivars to get basic information on the variation for the sesame breeding using principal component analysis. All characters except days to flowering, days to maturity and 1,000 seed weight showed significantly different. Seed weight per 10 are showed higher coefficient of variance. Capsule bearing stem length and liter weight showed positive correlation with seed yield per 10 are. The principal components analysis grouped the estimated sesame cultivars into four main components which accounted for 83.7% of the total variation at the eigenvalue and its contribution to total variation obtained from principal component analysis. The first principal component ($Z_1$) was applicable to increase plant height, capsule bearing stem length and 1,000-seed weight. The second principal component ($Z_2$) negatively correlated with days to flowering and maturity by which it was applicable to shorten flowering and maturity date of sesame. At the scatter diagram, Yangbaek, Ansan, M1, M2, M4, M7 and M9 were classified as same group, but M10, Yanghuk, Kanghuk, M5, M6, M12 and M13 were classified as different group. This results would be helpful for sesame breeder to understand genetic relationship of some agronomic characters and select promising cross lines for the development of new sesame variety.

Morphometric investigations of the leg characters of both sexes of brachypterous Korean N. lugens biotypes were made. Simple and multivariate statistical analyses revealed that the three N. lugens biotypes differed from one another. The amount of variation and segregation between and among the three biotype populations were approximated by the scatter plot diagrams based on the computed discriminant scores. The variables of leg characters provided the most significant segregations of three biotype populations, thus, categorizing the three biotypes as distinct intraspecific populations of N. lugens.

Leptochiton Gray, 1847 is one of the most ancient chiton groups which includes more than 130 species that occur in cold and deep waters worldwide. Due to their small-sized body, they are often confused as juveniles of other chiton species. Moreover, lack of morphological information makes species identification of this group very challenging. To date, only two Leptochiton species(L. fuliginatus and L. rugatus) have been reported from Korean waters. In this study, we found L. hakodatensis(Thiele, 1909) for the first time in Korea and described microscopic morphological characters of valves (tegmentum sculpture), girdle scale, and radula using a scanning electron microscopy (SEM). Leptochiton hakodatensis is morphologically similar to L. fuliginatus and L. rugatus, but differently characterized by having dorso-ventrally rounded (not carinated) intermediate valves, girdle (perinotum) scales sculptured with 4-7 longitudinal ribs, and bicuspid major lateral teeth of radula. In addition to morphological examination, we determined the partial mitochondrial cytochrome c oxidase subunit I(cox1) as a DNA barcode sequence information. This is the first report that describes microscopic characters (tegmentum of valves, girdle structure, and radula) of L. hakodatensis using a SEM. This study provides a morphological basis for describing Leptochiton species and discovery of a "hidden" species of this genus.

When turning to determining a subject position for the digital age, one may look beyond the invention of its technologies and instead begin with the development of its aesthetic of networked communities, nodal expression, and collaborative identity. Virginia Woolf's The Waves demonstrates this aesthetic in both form and content. In this paper, I will examine the role of collaboration in the form of interdisciplinary composition, arguing that Woolf's use of musical form and dramatic monologue and dialogue structurally secure an investment in collaborative models of expression. Digital texts taut their inherent multimodality, but such compositions are also evident in pre-digital texts. In addition, I will decipher the subject position Woolf puts forward in The Waves by looking closely at how the characters determine their own identity and existence when they are alone, when they interact with one individual, and when they congregate as a group. These are exemplified more specifically in the representations of Rhoda and Bernard as equally refusing to collaborate between a self-defined identity and a group defined identity; Bernard's channeling of Lord Byron while writing a love letter; and Woolf's use of the red carnation as a repeated image of the intertwined nature of the characters' collaborative identity and mutual dependence on one another.

This study was attempted to clarify the taxonomic problems that have been raised up to now in the study o section Telephium, genus, Sedum: the delimitation of taxa belong to Telephium group, their relationship, and nomenclatural confusion and the rank of Telephium group. Specimens were collected at 19 sites in Korea. The habitat, distribution, external morphological characters of habit, leaf shape, phyllotaxy, inflorescence, color of floral organs, floral formula, carpel, capsule, and micro-characters of pollen, seed coat, stigma and anther with SEM were examined. Through this study, the following results were obtained. The delimitation of taxa that belong to section Telephium in Korea and their relationship Nomenclatural errors were corrected. In S. rotundifolium Lee, species epithet“rotundifolium”is later homonym of s. rothundifolium Lamarck, so corrected to S. duckbongii Chung and Kim by article 64 of ICBN. Phyllotaxy was elucidated to meaningless, character in sect. Telephium. S. taquetii was a separate species from S. viridescens and not of its synonym. S. alboroseum Baker in Korea was S. erythrostictum sensu Master not of S. erythrostictum Miquel. By this study , taxa of sect. Telephium in Korea were arranged to 7 species. Considering interspecific relationship of sect. Telephium, S. duckbongii and S. alboroseum are considered to be more advanced forms and S. viridescens, S. taquetii, and S. viviparum to be more primitive forms among 7 species.

This study is a review of the clothing behavior of kidult group that is a new minority group in 21st century. Kidult is the compound word of kid and adult and refers the persons who have become adults but with the inclination to focus on childlike culture and consumption. As the background of the appearance of the kidult group these days, the prevalence of throwback fashions, high valuation of appearance, the phenomenon to prefer light things caused by economic depression, the individualism that does not care about others and the ageless phenomenon that the consumptions are mind age oriented, may be pointed out. The most prominent cloth behavioral characters of the kidult group are that they enjoy bounding color combinations such as candy color and. that cute t-shirts, crop pants and volume skirts of girlish look are easily found. Also, they enjoy toy-like ornaments and illustrated clothes or accessories and the school uniform fashion implying nostalgia for girl-hood and lovely make-up indicate the kidult inclination.
