The ultrastructure of epididymal spermatozoa obtained from Korean Native Goats was studied by means of electron microscopy, using thin sectioning techniques. The spermatozoan head was seen to be dorsoventrally flattened occupied mostly with the nucleus. The anterior two-third of the nucleus was covered with the acrosome and the rest with the postacrosomal sheath. A part of the postacrosomal sheath was separated from the nucleus forming the swelling. The cell membrane of the acrosome was separated from the acrosome and seen to be thick, but that of the postacrosomal sheath was coherent to the sheath. The articular structure of the neck appeared to show separate dorsal and vental plates of the capitulum which were followed by the striated columns of the connecting piece. Beneath the inner surface of the capitulum, the proximal centriole was found. There was no mitochondria on the upper part of the neck but there was membranous scroll material. The spermatozoan tail displayed a 9+9+2 pattern in the organization of the axial fiber bundle consisting of the dense fibers, double microtubules and a central pair. The dense fiber number 9, 1, 5 and 6 were larger in diameter than the rest of the dense fibers. The annulus was triangular in longitudinal sections.

This experiment was carried out to compare the effects of White and Red Ginseng on the blood picture and liver tissue of cockerels. Wale cockerels of Cobb strain were randomly allocated into five levels of White and Red Ginseng groups (0.25, 0.5., 1.0, 2.0 and 4.0g per 1㎏ of body weight respectively) and control group. Each lot was composed of 10 cockerels. At the end of preliminary feeding for one week, Ginseng was fad for six weeks. Blood picture was observed three times during the experiment. Liver tissue of each group was compared after 9 weeks of feeding. 1. The number of the red blood corpuscule (RBC) of treated chicken was increased as the experimental period was proceeded. The number of RBC of Red Ginseng group was higher than that of White Ginseng group. Red Ginseng was seemed to be more effective in RBC forming ability compared to White Ginseng. 2. There was no statistical significance in white blood corpuscule number between the groups. However, the lympocyte number of Red Ginseng and White Ginseng groups was about 2% higher than that of control group. It has shown that Red and White Ginseng stimulated antidisease activity. 3. There was no effect on the hemoglobin and hematocrit values, when Ren and White Ginseng were fed. 4. Red and White Ginseng stimulated fission, regeneration, the density of liner tissue and liver function. Red Ginseng was more effective than White Ginseng in these aspects.

The ultrastructure of epididymal spermatozoa obtained from Korean Native Cattle was studied by means of electron microscopy, using thin sectioning techniques. The spermatozoan head was seen to be dorsoventrally flattened. The anterior half of the nucleus was covered with the acrosome and the posterior half with the postacrosomal sheath which was a dense layer deposited on the inner aspect of the cell membrane. The articular structure of the neck appeared to show separate dorsal and ventral plates of the capitulum which were followed by the striated columns of the connecting piece. Beneath the inner surface of the capitulumm, the proximal centriole was found. The spermatozon tail displayed a 9+9+2 pattern in the organization of the axial fiber bundle consisting of the dense fibers, double microtubules and a central pair. The dense fiber number 9, 1, 5 and 6 were larger in diameter than the rest of the dense fibers. The annulus was triangular in longitudinal sections.

Testes from the domestic fowl have been examined by the electron microscopy in thin sections in order to observe the spermiogenesis and the structure of spermatozoa. The spermiogenesis can be divided into three stages: early spermatid, nuclear elongation, and matured spermatid. The inner membrane of mitochondria shows a markedly increased thickness compared to the outer membrane during the final steps of the spermiogenesis. The distal centriole composed of cylindrically shaped wall has been observed since the nuclear elongation stage. There are two cross sections of the nucleus in one spermatid cell owing to the curved long head. The acrosome of the matured spermatozoa is composed of the acrosomal cap and the acrosomal spine and there is no fibrous sheath around the axial filament complex in the principal piece.

To study the effect of antler on spermatogenesis, six cocks were administrated six times with 1.5g of antler per each cock, and other six cocks were allocated as the control group. The quality of the semen ejaculated at the interval of 72, 48, 24, 12, 6, 3, 1 hour and the testicular tissue were observed. 1. The amount of ejaculated semen, the number of sperm, the viablility of sperm, methylene blue reduction time and fertilization rate were increased in the antler administrated group compared with the control group. 2. Spermatogenesis was more active in the antler administrated group than in the control group when the testicular tissue were compared between two groups.

THIS experiment was performed to study on the effect of the growth and health of animal. Weight gain, feed efficiency and growth condition of internal organs of broiler and its resulting economical utility were investigated in this experiment of feeding velvet to broiler chicken. Three hundred chicken were applied to this experiment the treatment plots were divided 5 groups; T₁ (1cc of 0.375% velvet solution per chick), T₂(2cc), T₃(5cc), T₄(20cc), and the control (no velvet solution). The results obtained were as follows. 1. The plot which was treated with velet showed much more weight gain than the control (P$lt;0.01), and feeding velvet caused a useful effect en the feed efficiency and growth of internal organs. 2. Weight gain was high in the plot of T3, and T2, feed efficiency was high in order T1, T2 and T3. The plot of T1 was more economical than those of T3 and T2, so the use of adequate level of velvet was from 1 to 5cc. 3. It seemed that velvet improved the function of secretion of testosteron and sperm formation, because the growth testicle was promoted at the plots of T2, T1 and T3. As the velvet had a tendency of inhibition from growing thyroid at the plots of T3, T2 and T1, the metabolism was controlled by it, and the accumulation of nutritive substance was promoted The growth of the organs showed little difference in each treatment.

This experiment was conducted to investigate the effects of velvet on the growth of animal and obtain the basil data applying to the animal reproduction. Velvet was fed to broiler chicken to observe weight gain, feed efficiency, growth of internal organs, blood picture, testis tissue and comparision of both sex. The results obtained were summarized as follows. 1. Male was superior to female in weight gain and feed efficiency. 2. The growth of testis, thymus and heart of treated lots were showed significantly higher than those of control lots, and heart, lung and kidney were showed significant difference between male and female. 3. Comparing in histological view of testis at 8 weeks age, treated lots showed proliferation on spermatocyte, and more prolificacy on primary spermatocyte than control lots, and formed secondary spermatocyte but sperm was not formed. Regulation tendency was not observed in erythrocyte number, but treated lots showed significantly higher Hb content and hematocrit than those of control lots. As the time progressed, Hb content of treated lots was increased till 4 weeks age, and hematocrit was increased till 6 weeks, bur they were decreased after 4 and 6 weeks age, respectively.

위기관리관점에서 대학의 안전관리 법제 방안

배대식(Dae-Shik Bae) 한국콘텐츠학회 2008 한국콘텐츠학회논문지 Vol.8 No.4

이 연구에서는 대학영역에서의 안전관리 문제에 초점을 두고 대학의 양적 발전과 성장에 따른 위험 사회적 요소와 특성을 탐구하고, 안전관리에 관련된 법제문제를 연구하고자 한다. 대학캠퍼스는 인적자원과 물적자원, 지식정보자원이 집중되어 있는 사회의 축소판으로써 이러한 자원들을 위협하는 다양한 위험요인이 압축적으로 잠재되어 있는 영역이다. 그럼에도 불구하고, 지금까지 위험불감증과 무사안일주의로 인하여 캠퍼스내에 누적된 위험요소들을 인식하지 못하고 대학은 안전관리의 사각지대에 방치되고 있다. 최근에는 대학 연구실 안전사고 뿐만 아니라 사회양극화 현상의 심화, 스트레스와 장래에 대한 불안감, 정신질환의 증가로 인한 무동기범죄와 마약류 범죄, 사이버범죄 등 신종범죄에 대하여 체계적이고 종합적인 대책이 절실히 요구되고 있다. 따라서 대학에서 각종 안전사고와 재난을 예방하고 자원을 보호할 수 있도록 위기관리 관점에서 안전관리시스템을 구축할 수 있는 법제방안을 제시하고자 한다. This research will mainly focus on security issues in a university campus and delve into the risk factors and its characteristics due to the extreme polarization growth, and ultimately conduct research on legislative issues regarding safety & security management. A university campus is a miniature of the society, concentrated with human resources, material resources and knowledge information resources. It is also a region in which various underlying risk factors threaten these resources. However, due to the insensibility of danger and carefree indolence, these risk factors have been ignoring, leaving university campus amidst a dead zone. Currently, a systematic and synthetic measures not only for safety inside the laboratory but also for the new type of crimes such as cyber crimes and motiveless crime due to extreme polarization, stress, uneasiness about the future, increase of mental illnesses, and drug abuse are urgently required. Therefore, I would like to introduce a legislative program in a crisis management perspective that can prevent universities from danger and protect the resources which would ultimately create a new security system.
