Mating disruption experiments were evaluated and compared in several pheromone traps and sex pheromone composition ratios at commercial chestnut garden for developing alternative control method of D. punctiferalis. The highest attractive was shown in Delta traps at the effective sex pheromone ratio of 75:25 (E10-16:A1:Z10-16:A1). Comparisons of domestic and imported pheromone constituents were not significant difference in 90:10 (E10-16:A1:Z10-16:A1). But, there was significant difference in sex pheromone ratio of 75:25. D. punctiferalis was caught the highest number in Gongju area for attractive test using pheromone trap. Attractive effects with dose of pheromone were showed the highest at 2.5 mg/lure and 1 mg/lure in Gongju area and Cheongyang area respectively. However, there was no significant difference among pheromone dose in Buyeo area. These data could be useful for eco-friendly managing of D. punctiferalis in the chestnut farm.

Objectives : The dopamine-blocking effects and the associated side effects(amenorrhea, lactation, sexual dysfunction) of classical antipsychotics in schizophrenic patients have been studied for a long time. The purpose of this study was to find out these effects of new antipsychotics(risperidone, olanzapine) in schizophrenic patients treated with clinically relevant doses. Method : Plasma levels of both prolactin and testosterone were measured in 91 schizophrenic patients(28 taking haloperidol, 4-20mg/day ; 31 taking risperidone, 2-6mg/day ; 32 taking olanzapine, 5-20mg/day). Results : In male schizophrenic patients, the prolactin levels of risperidone group($76.44{\pm}38.85ng/ml$) and haloperidol group($60.26{\pm}20.74ng/ml$) had no significant difference, but were significantly higher than that of olanzapine($26.90{\pm}5.36ng/ml$). In female, the prolactin level of olanzapine group($36.66{\pm}17.55$) was significantly lower than those of risperidone($121.7{\pm}48.33$) and haloperidol group($161.66{\pm}37.53$). And prolactin level of risperidone group was lower than that of haloperidol group. While the testosterone plasma level of risperidone, haloperidol and olanzapine in both male and female schizophrenic patients had no significant difference. Conclusions : At doses known to be effective in popular clinical setting, prolactin level in patients taking risperidone was higher than that of haloperidol, while olanzapine showed no significant difference in terms of prolactin plasma level from haloperidol. New antipsychotics may not influence the testosterone plasma level.

Hematological and serum biochemical values were assessed from 20 clinically healthy Japanese Macaques raised in Everland Zoological Gardens and compared to the International Species Information System (ISIS) reference range that is used internationally as standard for wildlife animals. Taking our standard on sexual maturation at age 4, tRBC values in Macaques under age 4 were significantly lower than those over age 4, but the Hb and PCV values were significantly higher. Compared to the ISIS standard, the tRBC values in Macaques under age 4 were significantly lower whereas the Hb and MCHC values were significantly higher. Moreover, in the samples of Macaques over age 4, the PCV and MCV values were significantly lower than the ISIS standard. On serum biochemistry values the creatinine and amylase values in the Macaques under age 4 were significantly lower than those over age 4. In comparison with the ISIS standard, the values of ALT, ALP, BUN, IP, $Ca^{2+}$ and $K^+$ in the Macaques under age 4 did have no significant difference. The values of TP, GGT, tBil, amylase, TG and UA were significantly higher than the ISIS standard, but the values of albumin, AST, glucose, creatinine, cholesterol, CPK, LDH, $Na^+$ and Clwere significantly lower. In contrast, the values of TP, albumin, ALT, ALP, creatinine, cholesterol, amylase, TG, IP and $Na^+$ in the Macaques over age 4 did have no significant difference, but the values of GGT, BUN, tBil, UA and $Ca^{2+}$ were significantly higher, while the values of AST, glucose, CPK, LDH, $K^+$ and $Cl^-$ were significantly lower. On the other hand, there was no significant difference in hematological and serum biochemical values between the groups of male and female.

The purpose of this study was to survey the degree of awareness and practice concerning prenatal care among Korean women. In this study, 626women in Seoul, Sungnam City, and Yangju Kun were randomly selected to be given a questionare that was formulated by the researcher. The statistical analysis of the data was obtained by percentage scores and $X^2$ scores on each item by age, educational background, and regional areas. The general out come of the study were as follows. A. The Practice of Prenatal Care 1. Physical Activities: Concerning the hard work, about a half of the women took care of it by themselves, and the others treated it with help. Also it was found that they tried to reduce the amount of travel as much as possible during pregnancy. 2. Dietary Intake: It was revealed that no significant change were observed before and during pregnancy. 3. Drugs: It was revealed that they tried to avoid drugs as much as possible during pregnancy. 4. Emotion: About a half of the women said that the family atmosphere did not change before and during pregnancy. The others said it had improved after pregnancy. In their spare time, most pregnant women rested in bed, read books, and listened to music. 5. Husband's Support: Most of the women expressed that they needed thief-husband's support absolutely, especially with hard work. They moderated the sexual activities when they found that they were pregnant. B. Degree of awareness for Prenatal Care 1. Perception of Prenatal Care: Most women heard about prenatal care at least one time through family, friend, or mass-media. 2. Necessity of Prenatal Care: Most women recognized the necessity of prenatal care, and they thought that the relaxation of body and mind was important during pregnancy. 3. Influence of Prenatal Care: It was revealed that most women recognized the positive influence of prenatal care to the neonate. 4. Practice of Prenatal Care: It shown that the most of pregnant women took serious interest in prenatal care and they tended to be careful during pregnancy. Generally speaking, the difference in educational background seemed to affect most to the pregnant women's awareness and practice of prenatal care: the higher the educational achievement, the more cautious about the prenatal care. The difference in region seemed to affect considerably in most aspects of practice: women in urban areas preceeded the rural women in prenatal care. The age difference seemed to affect least in their prenatal care except the younger generation took more care in avoiding the use of drugs.

A preliminary experiment was conducted to produce fowl-typhoid resistant egg type breeds, using three brown egg layer breeders (ISA, Hyline, and Lohman) and two white egg layer breeders (ISA and Lohman). Various economic parameters were measured from day-old to mature stages using parent stocks of each breed. No significant difference in viabilities of mature hens from 34 to 66 wk of ages was found between brown(93.3%) and white(93.5%) egg layer breeders (P>0.05). Also, there was no difference in viabilities of mature cockerels. Although not significant, the mature body weights of brown egg layer breeders tended to be heavier than those of the white egg layer breeders both in hens and cockerels. No difference in feed intakes of mature brown and white hens were detected. Ages of sexual maturity of white and brown egg layer hens were 147.7 and 140.5 d, respectively (P<0.05). Egg production of white egg layer hens during 23-66 weeks age was significantly higher than their counterpart (81.4% vs. 75.0%). Comparisons of Haugh Unit, egg shape index, yolk color, and egg weight between brown and white eggs were not significantly different; however, the brown eggshells were thicker and stronger than those of white eggs (P<0.05).

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.

This study aims to investigate the female caregivers'experiences of aggression by nursing home residents, and to identify the policy strategies for violence prevention referred by the female caregivers. A total of 121 female caregivers with more than 6 months of working experiences had participated in this study. Of these, 56.2% had experienced verbal aggression, 51.2% physical aggression, and 27.3% sexual aggression, which reveals that client violence toward caregivers in nursing homes was at an alarming level. Although, physical and verbal violences were mostly caused unintentionally, about a half of the sexual aggression were caused deliberately. Aggression occurred the most when caregivers were providing the following services: changing the diapers or clothes, giving a bath, and serving meals. It was found that 'hitting' was the most common form of physical aggression and it was 'swearing' and 'touching or physical contacting' in the case of verbal and sexual aggression, respectively. Though there was a difference depending on the type of aggression, the most frequent reactions against client violence were to start a conversation or calm down the nursing home residents, and to leave the scene or ignore the incident. This means that the caregivers are coping very passively through resolving the aggressions by themselves, or overlooking the situation. The most frequently recommended strategy to prevent resident aggression was to provide educational programs on violence prevention to nursing home residents and caregivers(42.7%). Compared to the previous studies, this study indicates some differentiated strategies to prevent violence in nursing homes, which include hiring male caregivers, assuring directors to pay closer attention toward caregivers, using refined language between caregivers and residents, and keeping caregivers to wear appropriate clothes. Based on the study results, some policy recommendations on the prevention of client violence in nursing homes were suggested.

This study was carried out to select superior dual purpose hens which could spread to poultry farming for subsidiary work and general farmhouse. Three hundred and fifty chicks of 7 kinds of 2-way crossbred from mating of Rhode Island Red, New Hampshire and Australorps were tested for dual purpose performance. The results obtained were as follows: 1. The average viability of brooding, rearing and laying Period hen were 92.3% 98.3% and 93.1% respectively. There was significant difference at 1% level among crossbreds for brooding viability, but other viabilitys were no significant difference. 2. The average body weight of 8 weeks was 854.41g, but there was no significant difference among crossbreds, respectively. Average body weight at 300 days, 500 days were 2507.15g, 2632.25g respectively, but there was significant difference at 1% level among crossbreds. 3. Sexual maturity of individual and 50% egg production were 173.7 days and 199.4 days, respectively. There was significant difference at 5% level among crossbreds. 4. The average hen day egg production was 65.3% and the highest was R.N crossbred (70.5%). There was significant difference at 5% level among crossbreds and average hen housed egg Production was 20.2 eggs and the highest was 220.4 eggs in R.A. crossbred. 5. The average egg weight was 57.36g and the highest was A.N crossbred (58.3g). Therc was no significant difference among crossbreds. 6. The average feed consumption per hen per day by stag. was 42.9g (brooding period), 83.7g (rearing period), 131.1g (laying period). Average feed requirement per 1kg. egg production was 3.79 and th. R.A. crossbred was superiority (3.42). 7. On the basis of the results of this study, the R.A and R.N crossbreds were best for superior dual commercial chicks under farming management conditions.

Purpose: The purpose of this study is to find differences in the demographics of toxic exposed patients and substance between call based poison information data and hospital based poison information data. Methods: Seoul 1339 call-response data were used as call based poison data and toxic related injury surveillance data of the Korean center for disease control and prevention (KCDC) were used as hospital based poison data. Age, sex, the kind of exposed substance, reasons for exposure, and exposure routes were compared between two data sets. We analyzed the presence or not of documentation on the name and amount of exposed substance, symptoms after exposure in call based poison data. Results: Seoul1339 poison data included a total of 2260 information related to toxic exposure and KCDC poison data included 5650 poison cases. There was no difference in sexual distribution. Pediatric exposure and accidental exposure were more common in call based poison data. The most common exposed substances were household products in call based poison data and medicines in hospital based poison data, respectively. Documents regarding amount and time of toxic exposure and symptoms after toxic exposure were not recorded exactly in call based poison data. Conclusion: There were significant differences in age, reasons for toxic exposure, and the kinds of exposed substances. Poison information data from both pre-hospital and hospital must be considered.
