  • A high seed yield '232' was evaluated for morphological characteristics and tissue culture re-sponse. The effect of mowing and urea application on coverage in '232' was also studied and the results were as follows ;1.'232' produced high seed yield than any other lines, but its other characteristics such as coverage, establishment rate, stolon length, stolon number and colour change were not good. 2.Callus induction of '232'(52.9%) was relatively high, and higher than that of Z. sinica(49.0%). However, embryogenic callus formation of '232' was not as good as that of Z. japonica and Z. sinica. 3.Coverage of '232' was very much enhanced by mowing on July 18, but not at all by mowing on May 29 and September 4. 4.Urea application did not increase the coverage in '232',Therefore, it can be used as a breeding material rather than direct use.

  • This study examined the characteristics of total consumers' anti-sites on on-line and their changes according to the establishment year of consumers' anti-sites, the activities and the evaluation of consumers' anti-sites and their differences according to the characteristics of consumers' anti-sites. Total 649 consumers' anti sites were analyzed for examining the characteristics of total consumers' anti-sites and 18 anti sites were selected for examining the activities and the evaluations of consumers' anti site. The anti sites were evaluated by the index of using in preceding research. The result showed that about 90% of total consumers' anti-site were not activated, only a few consumers participated even in the activated sites, most activity of the anti-site were operated only on on-line not off-line, over half of anti-sites targeted to the company in the type of the subject of anti-site, and the majority of the external shape of anti-site were cafe. On the change of characteristics according to the opening year, the proportion of cafe and the sites acting on both on-line and off-line were increased year by year. The number of anti-sites was decreased since 2005 and the proportion of highly activated sites was lowest in 2005. On the activity of anti-sites, the number of providing the information were more than the number of presenting the complaint among the bulletin writings. The number of the bulletin writing were more in highly activated sites than in low activated sites. most of highly activated sites were problem solving type compared to the low activated sites. The number of the bulletin writings in company anti-sites were the most among three type of subject of anti-site. The number of the bulletin writings in cafe type were more than in home-page type. On the evaluation of consumers' anti-sites, most of the sites didn't update the notices and provided incomplete information how consumers participated in the protesting movements. The highly activated sites functioned better in most parts in providing a information, connection with other consumer and site manager, management of the site.

  • Transgenesis is a very powerful tool not only to help understanding the basics of life science but also to improve the efficiency of animal production. Since the first transgenic mouse was born in 1980, rapid development and wide application of this technique have been made in laboratory animals as well as in domestic animals. Although pronuclear injection is the most widely used method and nuclear transfer using somatic cells broadens the choice of making transgenic domestic animals, the demand for precise manipulation of the genome leads to the utilization of gene targeting. To make this technique possible, a pluripotent embryonic cell line such as embryonic stem (ES) cell is required to carry genetic mutation to further generations. However, ES cell, well established in mice, is not available in domestic animals even though many attempt to establish the cell line. An alternate source of pluripotent cells is embryonic germ (EG) cells derived from primordial germ cells (PGCs). To make gene targeting feasible in this cell line, a better culture system would help to minimize the unnecessary loss of cells in vitro. In this review, general methods to produce transgenic domestic animals will be mentioned. Also, it will focus on germ cell engineering and methods to improve the establishment of pluripotent embryonic cell lines in domestic animals.

  • The airpollutant may accelerate degradation of power line facilities, and may reduce the life of the electric facilities. In case of korea, there are a tendency that the density of air pollution may be increased by industrial development. while lack of research activity and establishment of a countermeasure on this issue. Recently the occurrence of electricity failure have been reduced on the power transmission and distribution lines. but the occurrence of electricity failure by insulator itself has been increased. It means that we should have develop more clear technique for detection of the wrong insulator. In this study to provide a method for detection of the insulator failure or effective management of the troubled insulator, we analyze the chemical composition of the insulator which used on power distribution line at the sea side locations. To define the relation between insulation and corona intensity, we design and develop an corona detector. We define the variation of insulation by pollution changes on the insulator and verify quantitative relation between corona and insulations using the corona detector.

  • ICLL 66 is the most widely ratified instrument of the IMO and is, along with the International Convention on Safety of life at Sea (SOLAS), the primary document setting forth internationally agreed ship safety standards. ICLL 66 set freeboard requirement based on experience gained from the first Load Line Convention in 1930 and on contemporary developments in ship design. Reexamination of ICLL 66 is indicated by the proliferation of novel ship designs for which it lacks adequate regulations and by significant advancements in analytical seakeeping and deck wetness prediction techniques now available to the designer. In this paper, the Freeboard Advisory Group reviews these issues against the changing climate of the marine industry and maritime administrations, discusses the state of the art in analytical seakeeping programs, and outlines a series of recommendations for the establishment of a new international load line convention for the next century. The steps needs for an international program at IMO are discussed and a new convention is proposed.

  • Through machine learning-based load prediction, it is possible to prevent excessive power generation or unnecessary economic investment by estimating the appropriate amount of facility investment in consideration of the load that will increase in the future or providing basic data for policy establishment to distribute the maximum load. However, in order to secure the reliability of the developed load prediction model in the field, the performance comparison verification between the distribution line load prediction models must be preceded, but a comparative performance verification system between the distribution line load prediction models has not yet been established. As a result, it is not possible to accurately determine the performance excellence of the load prediction model because it is not possible to easily determine the likelihood between the load prediction models. In this paper, we developed a reliability verification system for load prediction models including a method of comparing and verifying the performance reliability between machine learning-based load prediction models that were not previously considered, verification process, and verification result visualization methods. Through the developed load prediction model reliability verification system, the objectivity of the load prediction model performance verification can be improved, and the field application utilization of an excellent load prediction model can be increased.

  • We have characterized 4 human squamous carcinoma cell lines established from the larynx and hypopharynx area. All the cell lines were cultured in RPMI-1640 medium. During the growth they showed monolayer adherence pattern in culture flask. They showed tonofilament on transmission electromicroscopy which is characteristic of squamous cell epithelium. DNA finger-printing using Hinf-l proved them to be originated from different beings. Flow cytometric analysis revealed them to show aneuploidy. Immunohistochemical staining for cytokeratin was done using CK1, CK8.13, CK19 and CAM5.2 antibody, and produced various patterns of positivity. All the cell lines showed varying degrees of tumorigenecity in athymic nude mice when injected subcutaneously, but only heterotransplanted SNU-1041 cell line showed continuous tumor growth. Histopathologic findings of the heterotransplanted tumors were identical to those of the original tumors of patients. This study suggests that establishment of many different squamous cell lines might bestow great capability in researches of the head and neck cancer.
