The aim of study was to investigate genetic diversity for the calpain/calpastatin gene in three Hanwoo breeds [(Brown (n=62), Brindle (n=81) and Jeju Black (n=30)]. Random samples from three breeds of Hanwoo were selected and genotyped for the 7 SNPs of calpain/calpastatin using TaqMan method. Allele frequencies were investigated for CAPN1/CAST gene. Allele frequency of CAST2 SNP was 0.75, 0.59 and 0.22 for Brown, Brindle and Jeju black, respectively. The CAST3 revealed allele frequency of 0.59 and 0.57 in Brown and Jeju Black, while it showed very low allele frequency (0.07) in Brindle. In particular, favorable allele (G allele) for the CAPN1-2 SNP which was shown a strong association with tenderness in Taurine and Indicine cattle revealed 16% and 17% higher allele frequency in Brown Hanwoo (0.82) comparing Brindle (0.66) and Jeju Black Hanwoo (0.65). AMOVA demonstrated that among population variance occupied only 10% of total variance and among individual variance was 0%, while within individual variance was 90% of total variance. This result showed that population effect contributed very small portion of genetic to these three Hanwoo breeds, while within individual variance contributed large portion of genetic diversity within these Hanwoo breeds. In conclusion, three Hanwoo breeds (Brown, Brindle and Jeju black) showed a genetically homogeneous based on the 7 SNPs of CAPN1/CAST gene and it came from same ancestor to form modern Hanwoo breed.

This study was to investigate the effects on hematological indices and heinz body formation in various intensity, Male Sprague-Dawley rats were randomly divided into the control group, the low-intensity exercise group, nigh-intensity exercise group (n=7 in each group). Animals of the low-intensity exercise groups were put on exercise 30 min per 1 day, 5 days per week for 6-weeks. Animals of the high-intensity exercise groups were put on exercise 120 min per 1 day, 5 days per week for 6-weeks. Red blood cell count (RBC), hemoglobin (Hgb), hematocrit (Hct), mean ceil volume (MCV), mean hemoglobin corpuscular (MCH), mean hemoglobin corpuscular concentration (MCHC) were analyzed in automated hematology analyzer (ABX Hematology MICROS 60) from 10㎕ of whole blood. Erythrocyte morphology were evaluated in super vital (Brilliant cresyl blue stain) stained blood films. In the present results, Hg, MCHC in the high-intensity exercise group was significantly decreased compared with the different exercise intensity and the control group. MCV in the high-intensity exercise group was significantly increased compared with the different exercise intensity end the control group. Heinz body formation in the high-intensity exercise group was significantly increased compared with the different exercise intensity and the control group. In the present study, it can be suggested that intensity of exercise can influence hematological variables and heinz body formation. These findings suggest that high intensity exercise induces oxidative damage to erythrocyte.

This thesis studies the possibility of deconstructive metatheatre as a playspace in Pirandello`s Six Characters in Search of an Author and Beckett`s Waiting For Godot. Pirandello seems to be interested in the problems between reality and illusion, realism and anti-realism in life or theatre. He has made efforts to deconstruct the thick wall that lies in the realistic play derived from Plato and Aristotle, as well as the deep difference between life and theatre, actor and character, a text and a work, author and spectator. He uses such several techniques as signifiant wordplay, transformation, telegraphic word, position change, linguistic violence, pantomime, silence to deconstruct all theatrical obstacles for a shocking pleasant improvised performance. As he doesn`t regard real world and theatre as an organic complete unity full of absolute meanings but a plastic pluralistic playspace of disbelief and struggle, he searches for a new writing method based on Strindberg`s expressionism, Breton`s surrealism, and Artaud`s cruel ritualism. Although his experimental dark comedy, Six Characters in Search of an Author may be a mixture of tragic and comic, fantastic and realistic, it must be the beginning of anti-realistic performance followed into poststructual super-realistic theatre of Shepard and Mamet. Its intertexuality and signifiant wordplay connect itself with Derrida`s and Barthes` new creative writing based on Nietzschee`s pleasant aesthetics, that destroyed the binary linguistic system of western metaphysical philosophy. Influenced by Strindberg, Pirandello, Artaud, Breton, Sartre, Camus, and joyce, Beckett sings the song that life is a meaningless and monotonous performance of endlessly repeated routine. To suggest the debasement of metaphysical linguistic philosophy and the consequent breakdown of communication between inactive weak men organized by Rousseau`s and Descartes` reasonal philosophy, Beckett uses such linguistic tricks as word game, pun, allusion reminded of Williams` and O`Neill`s clownish black comedians that describe signifiant linguistic play for survival. Beckett deconstructs traditional concepts of realistic drama, as well as mechanical human relationships brought forth by formalistic structuralism or semiotics. His representative expressionistic absurd work, Waiting for Godot deals with the important dark problem of lingulsitic paralysis in majour signifiant signs(characters) that are psychically isolated from one another despite physical proximity. Trying to give spectators and characters the alternative to relieve them in entropy of linguistic stagnation, Beckett creates a stubborn comedian who can have a free command of word game with spiritual composure and pleasant aesthetics. Vladimir repeatedly talks to Estragon who gradually turns weak in the dramatic processing, to survive together in the dark negative situations. Although he may not be such active imaginative poet as William`s or O`Neill`s powerful insane clowns, Vladimir doesn`t stop his disseminating actions and meaningless signifiant wordplay like differance of traces in the black space that nothing happens.

The purpose of the study was to get the valuable data for developing the new natural fat soaps which have an excellent biodegradation performance. Thus, natural fat soaps mixed with the two types of detergents (AOS and LAS) on the various concentrations were made and the biodegradation of the samples were analysed by Dissolved Oxygen method using active sludge. Also, the results were compared with the commercial synthetic detergents and market soaps. The results from the study were the followings: I. The plant fat soap and the wasted oil soap with the concentration of 5 mg/i and 15 mg/1 had an excellent biodegradation rather than animal fat soap. 2, There was little difference among samples with the concentration of 5 mgtl, but there was much difference among them with the concentration of 15 mg/l. 3. The periods for consuming oxygen of wasted oil soap mixed AOS and LAS was the fastest.

This study was conducted with some questionnaires and psychological tests to investigate the behavioral trends and personality of the alcoholic's wives. The subjects were wives of 43 alcoholics who visited our department from March 1990 to July 1991, and wives of 43 patients with chronic medical illness. The results are as follows: 1) The level of education of the experimental group is lower than that of the control group, though statistically not significant. Alcoholics as a group earned much less money compared to the control group. 2) The differences between the present jobs and those at the time of marriage of the husbands in each group are not significant, and the differences of jobs between two groups in each time are not significant too. 3) Wives of alcoholics seem to have been more passie than the control group in determination to marry. 4) Alcoholics' wives usually treat their husbands either with decisively ordering manner of with indiffeence. 5) The preferred coping measures of the experimental group are shared concern, compliance and self-pity. 6) On MMPI, Hy scale is significantly higher in the experimental group than in the control group. 7) With digital coding of MMPI profile, the cumulation of the scales ofeach codes shows the higher frequency of occurrence of Pd scale and the lesser frequency of Ma scale in the experimental group. The differences are statistically significant. 8) It is suggested that the neurotic trends and the copings of wives of alcoholics are the results of the chronic cumulated alcohol-related stresses, the personality of wives have not effected the alcoholic marriage.
