This study was done to compare consciousness of biomedical ethics in nursing and general students. Participants were 382 nursing and general students at a college in S city. Mean score of consciousness of biomedical ethics(range:1~4) in nursing students was 3.04 and general students, 3.12. Thus, mean score of consciousness of biomedical ethics of two group were above the average and general students significantly higher than nursing students. Life-respect consciousness, perceived ethical values in nursing students were shown as significant predictors on consciousness of biomedical ethics and life-respect consciousness, sexual attitude, value regarding child rearing in general students. The most influential predictor of two groups was life-respect consciousness. To establish desirable biomedical ethics of nursing students, it is necessary that subjects related to biomedical ethics should be mandatory, and it is necessary to raise the proportion of credit for the curriculum.

Three species, Gymnogobius urotaenia, G. sp. 1 and G. sp. 2, collected at Hosan-river, Hosan-ri, Samcheock-si, Gangwon-do, Korea, were examined for the study of sexual dimorphism. The three species have peculiar nuptial pigmentation during the breeding season: all females of the three species showed an intense black coloration on the ventral part of the head, the pelvic fin, the anal fin and the margin of the first dorsal fin. There was a difference between G. sp. 1 and the other two species in 1/3 from margin of first dorsal fin. Namely, G. sp. 1 showed an intense black coloration, whereas the other two species had an intense yellow coloration. All females of the three species showed the same, intensely yellow coloration in the ventral part of the body. Males of G. urotaenia and G. sp. 2 had almost the same nuptial pigmentation, however the former showed diffuse black coloration in the anal fin, whereas the latter had an intensely black anal fin. Males of G. sp. 1 differed from those of the other two species in their yellow color on the ventral part of the head, the pelvic f ins, the anal fin, in contrast to the diffuse black coloration in those parts in the other species. The genital papilla of males was triangle-shaped, but that of females was heart-shaped. Significant differences between sexes include: G. urotaenia, 7 characters (body depth, head length, snout length, upper jaw length, head depth, pectoral fin ray length, eye diameter); G. sp. 1, 11 characters (body depth, head length, caudal peduncle length, caudal peduncle depth, snout length, upper jaw length, head width, head depth, anal fin ray length, pectoral fin ray length and caudal fin ray length); G. sp. 2, 10 characters (body depth, head length, caudal peduncle depth, snout length, upper jaw length, head width, anal fin ray length, pectoral f in ray length, caudal fin ray length and eye diameter). Of the 5 characters which showed differences in all three species (body depth, head length, snout length, upper jaw length and pectoral fin ray length), females had higher values than males only in body depth, whereas males values in all other characters. The upper jaw length was the most distinctive sexually dimorphic feature, the upper jaw extended beyond the posterior margin of the eyes (p<0.001) in males but not in females.

The present study was carried out to investigate the improvement of major production traits with the published data of twenty-two years'random sample tests held in Korea from 1966 to 1988. Eight traits-roaring viability, laying viability, age of sexual maturity, hen day egg production, hen-housed egg production, egg weight, feed requirement, 500 days body weight-were dealt with in this study. The results obtained in this study are summerized as follows； 1. Total mean value for rearing viability was 99.4% in 1980s. Mean value for rearing viability of colored hen was 99.5% and white hen was 99.06% in 1980s. Mean value for laying viability was increased by 0.98%, 0.86% and 0.86% per year in pool data, white hen and colored hen, respectively. 2, Age of sexual maturity was decreased from 171.1 day to 160.8 day in pool data during 1960s- 1910s but increased to 162.4 day in 1980s； and decreased from 160.5 day to 1595 nay in white hen but increased from 163.7 day to 166.1 day in colored hen during 1970s-1980s. 3. Mean values for hen-day egg production were increased by 0.96%, 1.09% and 0.63% per year in pool data, colored hen and white hen, respectively. 4. Mean values for hen housed egg production were increased by 45, 5.37 and 4.23 per year in pool data, colored hen and white hen, respectively. 5. Egg weight were improved by 0.22g and 0.25g per year in pool data and colored hen but decreased by 0.03g in white hen. 6. feed requirement were improved by 0.04, 0.05 and 0.1 per year in pool data, white hen and colored hen, respectively. 7. 500 days body weights were increased by 0.38g per year in pool data but decreased by 14.95g and 10.37g in colored hen and white hen, respectively. 8. Estimate of correlation coefficient between age of sexual maturity and other factors such as hen day egg production. hen housed egg production, egg weight and 500 days body weight were -0.4512, -0.2876, -0.4376 and 0.2045 in pool data； -0.358, -0.1530 0.3475 and 0.1208 in white hen； 0.0989, 0.1181, 0.2885 and 0.2248 in colored hen, respectively.

Purpose: The aim of this study was to evaluate the normal values of regional cerebral blood flow (rCBF) and cerebrovascular reserve (CVR) in normal children to aged volunteers using Tc-99m HMPAO, Materials and Methods: Thirty four right-handed normal volunteers (20 males, 14 females, mean age $40.3{\pm}24.9$ years, range 4 to 82 years) were underwent rost/acetazolamide (ACZ) brain SPECT using Tc-99m HMPAO and the sequential injection and subtraction method. rCBF was estimated on the basis of a semiquantitative approach by means of right/left ratio, region/cerebellum and region to whole brain ratios in (rental, parietal, temporal, and occipital lobes, basal ganglia, thalami, and cerebellum. CVR was measured by means of % perfusion increase calculated as % mean count change compared to rest rCBF in each regions. Results: Mean values of right to left ratios range from 1.004 to 1.018, rCBF was highest in cerebellum and lowest in basal ganglia and thalami. Frontal and temporal rCBF decreased while occipital and thalamic rCBF increased according to age. No sexual difference of rCBF was noted. Mean CVR was $29.9{\pm}12.9%$. Mean CVR significantly increased to late teens, and declined thereafter. After 6th decade, CVR in both frontal lobes, left parietal lobe and right basal ganglia decreased significantly with advancing age. There was no sexual difference of CVR. Conclusion: Quantitative assessment of CVR was possible by ACZ Tc-99m HMPAO brain SPECT. It revealed that rCBF and CVR changed according to age in normal Korean volunteers. There was no sexual difference.

The weekly liveweight gain, growing and stress parameters of quails bred using two different types of lighting for 6 weeks following hatching were examined in this study. The first type of lighting was 23 L:1 D, continuous lighting (CL), widely used in the commercial system and the second was a self-photoperiod (SP) system consisting of a continuously lit chamber and a dark chamber the quails could move to as they wished. On the first 15 days, no difference was found in liveweight gain between the two breeding systems. On the $6^{th}$ week when the trial was completed, the liveweight of the male quails upon which CL lighting was used was 159.03 g while the weight of males in the SP group was 174.43 g; these values in female quails of the CL group were 179.15 g and in the SP group were 200.68 g. The CL group had lower testis volume (TVOM, $cm^{3}$) and testis weight (TW, g) than the SP group, however there was no difference between the groups in testis weight/body weight rate (BWTW %). In female quails, the ovary weight (OW, g) and the ovary weight/body weight rate (BWOW, %) values were higher in the SP group. The CL light regime was concluded to cause stress in male quails (CL, Heterophil/Lymphocyte ratio (H/L): 0.27; SP, H/L: 0.17). In conclusion; the SP system allowing the quails to regulate their light periods increased liveweight gain and enabled sexual maturity to be gained at an earlier period than in quail on the CL system and improved their welfare.

To estimate the normal anal canal pressure in neonates, anal manometry was performed in 46 normal babies less than 6 days of age. Twenty-eight of the subjects were boys and 18 girls. All the subjects passed meconium within 24 hours after birth. Birth weights were above 2.4 kg. There were no sexual differences in birth weight, birth height, gestational age, postnatal age, or Apgar score (p<0.05). The mean manometry values were; anal sphincter length $18.6{\pm}3.9$ mm, high pressure zone (HPZ) $9.2{\pm}3.6$ mm, vector volume $2027.2{\pm}2440.7$ mmHg2cm, maximum pressure $42.3{\pm}17.4$ mmHg, and position of the maximum pressure $6.0{\pm}22.4$ mm. Only the HPZ of boys was longer than those of girls (p=0.005). In squeezing state, HPZ and the position of maximun pressure were not changed from resting state. HPZ, vector volume, and maximum pressure in boys were higher than those in girls. As the birth weight increased, the anal sphincter length (p=0.001) and the HPZ increased (p=0.047). The resting pressures of the anal canal were evaluated in three portions; /23 upper portion, $12.8{\pm}8.6$ mmHg, middle portion, $20.3{\pm}10.8$ mmHg, and lower portion, $26.1{\pm}12.9$ mmHg. These normal values may serve as guidelines for the evaluation, diagnosis and treatment of neonatal anal diseases.

With the increased frequency of crime such as assaults and sexual violence, the reliance on CCTV in arresting criminals has increased as well. However, CCTV, which should be monitored by human labor force at all times, has limits in terms of budget and man-power. Thereby, the interest in intelligent security system is growing nowadays. Expanding the techniques of an objects behavior recognition in previous studies, we propose a system to detect forms of violence between 2~3 objects from images obtained in CCTV. It perceives by detecting the object with the difference operation and the morphology of the background image. The determinant criteria to define violent behaviors are suggested. Moreover, provable decision metric values through measurements of the number of violent condition are derived. As a result of the experiments with the threshold values, showed more than 80% recognition success rate. A future research for abnormal behaviors recognition system in a crowded circumstance remains to be developed.

In this study, physical, social and psychological repression embodied by the body and clothing are referred to instinctual, power and creative desires, respectively, from the point of biological, social and aesthetic views. Desire refers to a behavior to overcome men's imperfections with individual security, sense of belonging and the pursuit of an ideal, which are obtained by living as a social creature. Repression through the body is sub-categorized depending on whether it is temporary or permanent. Repression expressed through clothing is seen through revealing/concealing, contraction/expansion, and deconstruction/ reconstruction. What enables human beings to embrace changes in fashion without fierce resistance or backlash is the changes of formativeness demonstrated by repression through the body and clothing. The aesthetic values drawn from the exhibition of repression and on the body and clothing are categorized into narcissism, fetishism and aestheticism. While narcissism is an instinctive desire grounded on the originality and confidence of the self that results in refusing repression, fetishism is a desire for power that expedites repression in the pursuit of materialistic value or sexual fantasy. Aestheticism is a desire for creativity that symbolizes the body-and-clothing repression in the pursuit of aesthetic idealism. Repression evokes desire, and the pursuit of desire leads to another repression. The aesthetic values of desire for instinct, power and creativity can be substituted with each other for interpretation according to the attitudes of an initiator, a user and a spectator.

A total of 352 specimens of congeneric species of Agkistrodon was collected and morphometric analysis and starch-gel electrophoresis were carried out in order to investigate the taxonomic status of this genus. The results obtained in this study are as follows: Morphometric analysis 1. Three species are recognized based on Gloyd's criteria. There was no specimen that was doubtful to classify correctly. Therefore, it seems that Gloyd's morphological characters are good criteria to identify each species. 2. All three species are sympatric at two localities (Mt. Seolag, Gangwon-do, and Mt. Deogyu, Jeonra-bugdo) and A. caligino년 and A. b. brevicaudus are sympatric at Gwangneung and Mt. Yongmun, Gyonggi-do. No hybrids were found in these sympatric localities. 3. Notable sexual dimorphism was found in meristic characters. 4. A. saxatilis has signicantly more number of ventrals and shorter tail ratio than other two species. 5. There were no significant meristic character differences between A. caligino년 and A. b. brevicaudus. Genetic analysis 1. Among 26 loci investigated, 12 loci (46.1%) were identical in their mobility, 4 loci (15.4%) were nearly identical with minor frequency differences, and 10 loci (38.5%) showed interspecific mobility difference. 2. The average proportion of polymorphic loci was 9.03%. This is considerably less than that of other vertebrates. 3. The average S and D values between species are .695 and .342 respectively. These values indicate that three taxa are distinct species. 4. A. caliginosus is genetically more related to A. saxatilis than to Agkistrodon, namely A. b. brevicaudus, A. caligino년 and A. saxatilis, as proposed by Gloyd. Far from being mere morphological variants, as suggested by Kang and Yoon (1975), they are highly distinctive evolutionary units.
