  • Korean textile and fashion companies have played a major role not only in developing the Korean economy since Korea's industrialization started in the early 1960s but also in providing opportunities to form and expand chaebols (conglomerates of family-owned businesses). This study reviewed and analyzed the historical development of chaebols, which started the fiber/textile/fashion business before the 1960s and maintained their chaebol status until 2010. The Samsung, Samyang, Kolon, Taekwang, Hyosung, LG, and SK groups were included in the study, and data were collected from diverse sources, including the publications and websites of the chaebol companies, newspapers, magazines, and research articles. The strategies of the companies at the corporate and group levels were examined based on the corporate lifecycle, which consists of existence, growth, maturity, rebirth, and decline stages. The results showed that all the analyzed companies actively engaged in product line expansion during the growth stage. Vertical integration, especially backward integration, was common during the growth stage. Some groups established new companies to manage additional product lines and integration, while others pursued growth strategies mainly at the corporate level. The rebirth stage occurred in only a few companies and groups. Some seemed to be going through the decline stage, and the rest of the groups exited the textile and fashion business.

  • We investigated the reproductive cycle with gonadal development of the female Cyclina sinensis by histological observations and seasonal changes in biochemical components of the adductor muscle and visceral mass tissues were studied by biochemical analysis, from January to December, 2001. The reproductive cycle of this species can be classified into five successive stages: early active stage (February to April), late active stage (March to June), ripe stage (May to August), partially spawned stage (July to October) and spent/inactive stage (September to February). Total protein contents in the adductor muscle tissues reached the maximum in February (early active stage) and appeared the minimum in June (ripe stage), while their contents in the visceral mass tissues reached the maximum in the late active and ripe stages (June) and gradually decreased from July (partially spawned stage) to November (spent/inactive stage). Changes in total protein contents showed a negative correlationship between the adductor muscle and visceral mass tissues (r = -0.499, p = 0.099). Total lipid contents in the adductor muscle tissues reached the maximum in January (the inactive stages) and their contents gradually decreased from February. Their contents in the visceral mass tissues, however, reached the maximum in June (late active and ripe stage) and gradually decreased from July (the partially spawned stage). On the whole, total lipid contents showed a negative correlationship between the adductor muscle and visceral mass tissues (r = -0.631, p < 0.05). Therefore, These results indicate that the nutrient contents of the adductor muscle and visceral muscle tissues change in response to gonadal energy needs. Glycogen contents in the adductor muscle tissue reached the maximum in March (early and late active stages) and decreased from July to September (partially spawned stage). while their contents in the visceral mass tissues reached the maximum in June (late active and ripe stages) and gradually decreased from July (partially spawned stage). Thereafter, their levels gradually increased in November (spent/inactive stage). On the whole, changes in glycogen contents appeared negative correlationship between the adductor muscle and visceral mass tissues. However, they showed no significant different (r = -0.307, p = 0.331).

  • This study investigated the effect of variation in the number of somatic-cell-cloned embryos and their developmental stage at transfer on pregnancy, as well as the influence of the estrus status of recipient pigs on in vivo development of cloned porcine embryos after embryo transfer. For somatic cell nuclear transfer (SCNT), fibroblast cells were obtained from a male porcine fetus. Recipient oocytes were collected from prepubertal gilts at a local abattoir and then cultured. After SCNT, reconstructed embryos of different numbers and developmental stages were transferred into recipient pigs. The developmental stage of the cloned embryos and the number of transferred embryos per surrogate showed no significant differences in terms of the resulting cloning efficiency. However, the pregnancy rate improved gradually as the number of transferred cloned embryos was increased from 100-150 or 151-200 to 201-300 per recipient. In pre-, peri-, and post-ovulation stages, pregnancy rates of 28.6%, 41.8%, and 67.6% and 16, 52, and 74 offspring were recorded, respectively. The number of cloned embryos and estrus status of the recipient pig at the time of transfer of the cloned embryo affect the efficiency of pig production; therefore, these variables should be particularly considered in order to increase the efficiency of somatic cell pig cloning.

  • The "stage albinism line of winter wheat" FA85 was a specific natural mutant strain on leaf color. This physiological mutation was controlled by cytogene. In order to reveal the genetic and biochemical mechanism of albinism, 2-DE was used to investigate the difference of chloroplast protein expression pattern between FA85 and its parent wheat Aibian 1. From the results of 2-DE gels analysis, approximately 683 spots were detected on each gel, and 57 spots were expressed differently at least two-fold. Using MALDI-TOF/TOF MS, 14 of 57 spots were identified, which could be categorized into four classes: carbon metabolism, energy metabolism, defense/stress response and signal transduction. Compared with the parent wheat, the expression of ATPase-$\gamma$ and GP1-$\alpha$ was up-regulated in FA85, and of other proteins was down-regulated. Together, we concluded that the expression of chloroplast proteins had changed obviously in FA85, which might be related to the leaf color mutant.

  • In this study, characteristics of chick primordial germ cells (PGCs), which is the founder cell of the germline, and gonadal development of the chick embryo between 12hrs and 6 day of incubation were investigated by transverse serial sections of chick embryos under the light microscopic observation. In embryo stage 20 (3 day of incubation), there are a lot of PGCs at the mesenchym, which were moving to the thickened epithelium (gonadal ridge). The PGCs arrive at both right and left gonad primordial in equal number prior to stage 24 (4 day of incubation), but in the following stages, the distribution of the PGCs became asymmetrical. More PGCs colonized the left than the right gonad, but the reason for the unequal distribution of PGCs is uncertain. The PGCs have mostly settled in the gonadal ridge (GR) at 6 day embryo. This study was conducted to investigate characteristics of the PGC migration and gonadal formation and observe the best condition for PGC isolation, culture and to attempt the possibility of the production for transgenic germline chimeras with manipulated PGCs.

  • Purpose: While there are a number of studies on children with disabilities, there have been few studies on mothers of children with autism. The purpose of this study was to explore the process of life transition of mothers who have children with autism. Methods: From June 2007 to May 2009, the researcher interviewed 15 mothers of children with autism living in Seoul City, Gyeonggi or Chonbuk Provinces, and then analyzed the data gathered using the constant comparative method of grounded theory. Results: "Living together holding a string of fate" was a core category showing along the continuum of life. The basic social process of life transition encompassed 5 stages: stages of denying, wandering, devoting, mind controlling, and finally accepting. These five stages proceeded in phases, though returned back to the wandering stage occasionally. Conclusion: This study has opened the door to understanding how mothers of children with autism experienced life transition. The findings suggest that differentiated support and care at each stage should be given and there is the need to develop transition assessment tools for mothers of children with autism.

  • Influenced by Constructivism Art, Constructivism theatre projected the future with the help of participating artists and the development of new technologies. Therefore, this thesis studied the stage costumes in the plays of Meyerhold who represented Constructivism Play and showed its characteristics. The stage costumes in Meyerhold's plays followed the rules of Constructivism Play and showed several unique characteristics, such as the Bio-mechanic as a characteristic in his plays, functionality that facilitated the movement based on Taylorism, simple shapes, and easy cutting. Constructive artists saw the stage of constructive plays as a laboratory where they can display their designs, directly portraying future life forms through stage costumes and props. Stage costumes were no more a supporting tool that had described the play. Following the new concept of stage costumes, working costumes and stage costumes came to be regarded as the same. In turn, this led to new models and special costumes such as sportswear or specialized garments. Constructivism artists foresaw the future through the plays, with their fundamental basis for stage costumes shown in the later works of ordinary costumes.

  • Purpose: This research was conducted to explore the relationship between spiritual well being and life attitude among breast cancer patients who were operated, and to increase understanding for wholistic nursing care. Method: With spiritual well being from quality of life questionnaire in breast cancer survivors (QOL-BR 23) of Ferrell et al (1998) and Life attitude profile (LAP) of Recker & Peacock (1981), the data were collected by research assistant in a sample of 56 women with stage 1-stage 3 breast cancer at surgery OPD after follow-up care. Result: Mean spiritual wellbeing score of subject was 5.83 (0-10) and life attitude was 4.96 (1-7). There were significant differences in life attitude according to monthly income (F=3.22, p=.03), and in spiritual wellbeing according to monthly income (F=4.16, p=.01) and religion (t=-3.67, p=.001) among demographic characteristics. There was significant difference in spiritual wellbeing according to the period passed after operation (F=2.89, p=.04) among disease characteristics. From life attitude domain, the mean score of "will to meaning" was the highest (5.30) and "existential vacuum" was the lowest (4.58). There was a significant relationship between spiritual wellbeing and "will to meaning" subscale of life attitude (r=.521, p=.000). The correlation coefficient showed r= .513 between spiritual well being and life attitude. Conclusion: Nurses could promote positive life attitude for breast cancer patients by improving spiritual well being with the encouragement of having religion expecially for long term breast cancer survivors in the process of their rehabilitation.

  • Root-feeding Scarabaeidae, particularly white grubs are considered among the most harmful coleopteran insect pests in turfgrass. In this work, sixteen entomopathogenic fungal species were assayed against flower chafer beetle, Protaetia brevitarsis (Coleoptera: Scarabaeidae) and Metarhizium anisopliae JEF-314 showed high virulence. The control ability of the isolate JEF-314 has been in detail tested for a model insect flower chafer beetle. Further analyses showed insect stage-dependent virulence where the fungal virulence was the highest against smaller instar larvae. Additionally, we confirmed that millet-based solid cultured granule was effective against the soil-dwelling larval stage. The isolate also showed a similar ability for a representative pest (Popillia spp.) in laboratory conditions. Our results clearly suggest a high potential of M. anisopliae JEF-314 to control the flower chafer beetle, possibly resulting in controlling of root-feeding white grubs in turfgrass. Based on the insect life cycle and susceptibility to the fungus, late spring and summer time would be the optimum time to apply JEF-314 granules for an effective control. Further characterization of the efficacy of the fungus under field conditions against the Scarabaeidae beetles might provide an efficient tool to control this beetle in an environment-friendly way.
