The objectives of this research are to determine the seasonal and varietal differences of total digestible nutrients(TDN) and in vitro dry matter digestibility(1VDMD) of tall fescue grown in Takwalyon areas, based on the data of preceding paper(Lee et al. 1994b). The results are may be summarized as follows : 1. The values of total digestible nutrients(TDN) and in vitro dry matter digestibility(1VDMD) in 1st cutting were lower than the values of 2nd and 3rd cutting, and it was due to different stages of growth and seasonal difference of climatic conditions in this areas. 2. The relative yield(RY) had negative significantly correlation with in vitm dry matter digestibility(1VDMD) of 1st cutting. 3. Total digestible nutrients(TDN) indicated high positive significant correlation with in vitro dry matter digestility (IVDMD) in all cuttings. 4. The variety of Johnstone showed a high values of total digestible nutrients(TDN) and in vitm dry matter digestibility(1VDMD) of 2nd and 3rd cutting, but Fuego was lower than the other varieties.

During the last three decades considerable advances has been made in goat embryo production and transfer technology. The Korean native black goat is the most useful domestic ruminant in this country for biological investigation and application because it has a lot of merits such as relatively short generation period(1 vs 2 year for a cow), easy of handling, well adaptation, high fertility, convenient and inexpensive. This article covers the methods of superovulation, estrus synchronization, embryo collection and transfer techniques, pregnancy diagnosis and subsequent pregnancy and kidding rates for the production of transgenic Korean native black goats. More than one hundred goat kids have been produced as a result of our transgenic goat project via microinjection of foreign gene into pronuclei, in vitro culture, transfer of various stages of fresh and frozen-thawed microinjected embryos into oviducts or uteri of recipient does. We have got two transgenic goats carrying a transgene targeting the expression of recombinant human granulocyte colony stimulating factor(hG-CSF) to the mammary gland so far. Since collection and transfer of embryos in this species is usually accomplished by laparotomy, exteriorization of the reproductive tract for surgical embryo collection leads to the formation of post-operative adhesions. Nonsurgical or laparoscopic technique to reduce adhesions from repeated surgeries has great advantages in improving embryo production and transfer especially from valuable donors. We will discuss this later.

Purpose: The purposes of this study were to understand the coping experience that family caregivers undergo during the process of care, to grasp coping behaviors used to solve problems and, finally, to develop a substantive theory by analyzing the coping process. Method: The methodology of collecting and analyzing data used in this study followed the ground theory. Data were collected through in-depth interviews with open-ended and descriptive questions about the subjects' coping experiences. The survey was conducted between May 2006 and August. The subjects of this study were 10 women. Result: The result of the study is as follows. Core category of This Study was "Self-Sacrifice". And The coping process of family caregivers while taking care of the industrial disaster victim was found to have five stages: shocked stage; undertaking stage of new role; skilled stage; exhausted stage; and desiderating stage. Seven coping behaviors were found to reduce the stress of role and anguish resulting from care. Conclusion: The result of this study is helpful for developing effective industrial nursing strategies suitable for each coping stage. It is necessary to practice nursing mediation and to analyze the change about nursing effect and family caregivers' adaptation.

In this paper a simple mathematical model is presented for estimating the natural frequencies and corresponding mode shapes of a tall building with outrigger-belt truss system. For this purposes an equivalent continuum system is analyzed in which a tall building structure is replaced by an idealized cantilever continuum beam representing the structural characteristics. The equivalent system is comprised of a cantilever shear beam in parallel to a cantilever flexural beam that is constrained by a rotational spring at outrigger-belt truss location. The mathematical modeling and the derivation of the equation of motion are given for the cantilevers with identically paralleled and rotational spring. The equation of motion and the associated boundary conditions are analytically obtained by using Hamilton's variational principle. After obtaining non-trivial solution of the eigensystem, the resulting is used to determine the natural frequencies and associated mode shapes of free vibration analysis. A numerical example for a 40 story tall building has been solved with proposed method and finite element method. The results of the proposed mathematical model have good adaptation with those obtained from finite element analysis. Proposed model is practically suitable for quick evaluations during the preliminary design stages.

Purpose: The purpose of this study was to investigate the alopecia experience in adults and to explain the process of their experiences. Methods: Using a grounded theory methodology, 18 interviews were performed with fourteen men and four women, 34~57 years of age, suffering from alopecia. Data were analyzed using the constant comparative analysis method. Results: The core category emerged as "inescapable fetters". adults with alopecia engaged in three stages: embarrassment, seeking solution, and acceptance phase. Causal conditions were a vicious cycle of stress, biological factors and poor life style. Contextual conditions were recognition of irreversibleness, negative social awareness, and marriage. The central phenomenon of the adaptation process among the adults with alopecia was withdrawn life due to negative body image. Action/Interaction strategies included rely on medical treatment, efforts to take good care of hair, research for information treatment, efforts to cover up hair loss, and mind control. Intervening conditions were time cost, economic cost, support of surrounding people. Consequences was burden of unfinished lifetime homework. Conclusion: When caring for these adults, it is important to identify needs, allow patients to express what they want at that moment and support them in maintaining a daily life.

Endobiotic microalgae inhabit various groups of organisms, including bivalves. In this group, the association between the giant molluscs Tridacna and Symbiodinium is one of the most recognizable. This consortium allows hydrobionts to survive in oligotrophic waters by regulating their metabolism. The available research has provided an understanding of the interaction and adaptation of these symbionts, but the problem of the beginning of the formation of these relationships remains unresolved. In the case of Tridacninae, symbiosis is essential for the survival of bivalves, in contrast to representatives of the Mytilidae and the Coccomyxa found in them. A few works devoted mainly to the morphological aspects of invasion have shown that endobiont causes inflammation and pathology. Having data to clarify the exact "diagnosis" of the interaction of these organisms is not enough. It is possible that the relationship between bivalves and Coccomyxa is in the early stages of being established, which may lead to mutualism or parasitism in the future. We assume that the analysis of works on the symbiosis of Symbiodinium and bivalves will facilitate the course of research for the less studied Coccomyxa and their hosts. By postulating the Coccomyxa represent a unique evolutionary model for the formation of a symbiotic system, it is possible to use this system to study the interaction of organisms during their initial contact. The identified signalling pathways and mechanisms that allow the photobionts to evade host immunity can be useful for constructing new forms of symbiosystems.
