The purpose of the study is to examine the realities of the high school students's aggressive behavior, and to analyze factors causing aggressive behavior. Subjects were 418 Humanity High School students of 2nd grades in pusan. Analysis methods were used to frequency, percentage, t-test, one way ANOVA, Pearson's correlation, and multiple regression of SPSS program. The results are as follows ; 1) Male students are more aggressive than female students. 2) The more verbal aggression is the more physical aggression. 3) Students with the experience of parent-child violence are more aggressive. 4) Students with observation of parents's violence are more aggressive. 5) Family's social economic status is not related to the aggressive behavior. 6) Male students not admitted by teacher are more aggressive in verbal and physical behavior. 7) Female students not admitted by friend are more aggressive in verbal and physical behavior. 8) Students with deliquent friends are more aggressive in verbal and physical behavior. 9) Students with Academic anxiety are more aggressive in verbal behavior. 10) the variables influential to verbal aggressive behavior are sex, a delinquent friends and academic anaxiety. These factors explain 23.5% of the total variance of verbal aggressive behavior variables. The variables influential to physical aggressive behavior are a delinquent friends, sex, experience of parent-child violence and teacher's denial attitude. These factors explain 29.6% of the total variance for physical aggressive behavior variables.

Purpose. With a sample of cognitively impaired nursing home residents and nursing staff, the following were examined 1) the proportion and nature of aggressive behavior, 2) the frequency and types of aggressive behavior, 3) the difference between the residents who demonstrate aggressive behavior and those who do not demonstrate aggressive behavior (age, mental status, functional status, and pain, length of nursing home stay), and 4) nursing staff responses to aggressive behavior by residents. Methods. A cross-sectional descriptive study design was used. Data were collected from cognitively impaired nursing home residents (N=205) and nursing staff (N=60) at two nursing homes using Ryden Aggression Scale I and II, Mini-Mental State Exam, Modified Barthel Index, Verbal Descriptor Scale, and aggressive behavior management questionnaire. Data were analyzed using descriptive statistics including t-test. Results. About $62.9\%$ residents were found to be aggressive and $38.5\%$ were both physically and verbally aggressive. Pushing, making threatening gestures, hitting, slapping, cursing/obscene/vulgar languages, making verbal threats were occurred frequently. Aggressive residents were significantly older, had more cognitive impairment, had more pain, and stayed longer in the nursing home when compared with non-aggressive residents. Considerable proportion of nursing staff responded to aggressive behaviors inadequately. Conclusion. Aggressive behavior among cognitively impaired nursing home residents is prevalent thus needs to be prevented and reduced. Along with environmental modification, educational programs for nursing staff and family caregivers need to be developed and implemented so that they can have extensive knowledge and skills to manage aggressive behaviors.

This study was to examine the characteristics of aggressive behaviour of dementia patients. It was based on the observation of the patients in a facility for dementia patients. Observation continued for two days from 9a.m. to 5p.m .. aggressive behavior was recorded using the instrument of Ryden. The result of this study is as follows. 1. appearance rate of aggressive behaviour During two days $74\%$ of the patients did aggressive behaviour(first day-$41.8\%$. second day-$62.8\%$). The average aggressive behaviour per person was 1.65. 2. types of aggressive behaviour Aggressive behaviour was the most frequent in verbal domain(157 case; $52.5\%$). Physical domain was the second$(136case;\;45.5\%)$, and sexual domain was the last$(6 case;\;2.0\%)$. More concretely, abusive/vulgar language$(74case;\;24.7\%)$ was more than anything else. Aggressive language$(65case;\;21.7\%)$, pushing$(39case;\;13.0\%)$, intimidating posture$(21case;\;7.0\%)$. slapping $(18case;\; 6.0\%)$ followed it. 3. correlation to other factors such as sex. age etc. The average aggressive behaviour of female(2.07) was higher than that of male(1.23) (p=.05). Age also had meaningful correlation to the frequency of aggressive behaviour(p=.04). All the other factors-the period of living in facility, the seriousness of dementia. movements in daily life. CAPE, emotional state. the extent of trouble in cognition- have nothing to do with the frequency of aggressive behaviour. 4. the time, place and the target of aggressive behavior Aggressive behaviour appeared more frequently in the afternoon $(138case;\;46.4\%)$ than in the morning or at lunch time. The patient's room ranked the first in the list of places where aggressive behaviour took place $(162case;\; 54.5\%)$. Nursing personnel topped in the target of aggressive behaviour$(119case;\; 39.8\%)$. 5. the preceding causes of the aggressive behavior the most frequent preceding causes of the behavior was the stimulus of another residents $(133case, 44.4\%)$ and that of nsg personnel was few relatively$(65 cases,\; 21.7\%)$. 6. Nursing personnel used verbal reaction most frequently$(40 cases,\; 51\%)$ and in a behavioral reaction they used physical restraint $(12 cases,\; 17.1\%)$ most frequently. In the reactions of nsg personnel. the rate of undesired reaction was high$(41cases,\; 44.28\%)$. and in that of the attacked residents, the usual reaction was most frequent $(80cases,\; 65.0\%)$. In the future it is needed to investigate the characteristics of aggressive behavior of dementia patients, and based on this the method of intervention must be developed. Today the number of dementia patient increases so nurses must strive to encounter aggressive behavior more desirably.

This study verified the effects of violent PC games and aggressive personality on aggressive behavior and aggressive intention as predicted by GAM in Anderson and Bushman (2002), and a correlational study and experimental research were carried out to corroborate a differences of the effects of the two variables according to the developmental levels. The correlational study showed that aggressive personality was an explanatory variable for aggressive behavior; however, exposure to violent PC games was not a significant factor, contrary to the predictions by GAM. It has been clarified that the effects of the two variables influenced aggressive behavior in a different way according to the developmental levels. Further, no positive relation existed between repetitive (chronic) violent PC game plays and aggressive personality. The experimental research analyzed the differences of aggressive intention in each of the experimental conditions designed with a 2(PC games types: violent vs. non-violent) x 2(aggressive personality: high vs. low) x 2 (developmental levels: middle school boys and college students) between-subjects factorial design. As a result, violent PC games had an effect on aggressive intention for the middle school boy group, while it was supported that aggressive personality had an effect on aggressive intention for both middle school and college students. Noticeably, the primary hypothesis in the study has been supported that the effects of violent PC games and aggressive personality on aggressive intention vary according to different age groups. In conclusion, the effects of violent PC games and aggressive personality as predicted by GAM have been confirmed in parts; however, future studies on GAM must be necessarily supplemented with the developmental perspectives, as it has been ascertained that the effects of the variables vary according to the developmental levels.

Purpose: This study aimed to determine the mediating effects of aggressive stress response on the association between clinical practice stress and clinical practice satisfaction in ophthalmic optics majors and provide basic data that could help form opticians' professionalism and make clinical practice more effective. Methods: This study was conducted in 236 sophomores and juniors in Daegu and North Gyeongsang Province who had finished clinical practice. Hierarchical regression analysis and mediating effect testing were performed to determine the associations among clinical practice stress, clinical practice satisfaction, and aggressive stress response and determine the mediating effects of aggressive stress response on the association between clinical practice stress and clinical practice satisfaction. Results: Clinical practice stress was significantly negatively correlated with clinical practice satisfaction and aggressive stress response (p<0.01), and aggressive stress response was significantly positively correlated with clinical practice satisfaction (p<0.01). The association between clinical practice stress and clinical practice satisfaction was more likely to be explained by the addition of clinical practice stress than by being aggressive stress response controlled, which statistically significantly met the criteria for mediating effects (p<0.001). Conclusions: It is necessary to pay more attention to program development and teaching methods within the department of ophthalmic optics so that ophthalmic optics majors can utilize aggressive stress response to overcome clinical practice stress effectively and improve clinical practice satisfaction.

Purpose. The purposes of this study were to 1) describe the type and frequency of aggressive behavior of cognitively impaired nursing home resident, 2) develop a caregiver training program on prevention and management of aggressive behavior, 3) examine the effects of caregiver training program on the incidence of aggressive behavior of cognitively impaired nursing home resident, and 4) examine the effects of caregiver training program on nursing staff's aggressive behavior management skills. Methods. One-group, time series, quasi-experimental design with a pre-test and two post- tests was used. Data were collected from cognitively impaired home residents (N = 32) and nursing staff (N = 36) in a proprietary nursing home using Ryden Aggression Scale I, II, and Aggressive Behavior Management Scale. Data were entered and analyzed by descriptive statistics and repeated measures ANOVA. Results. Incidence of aggressive behavior was high with a mean score of 3.09 (SD = 3.11) at baseline. Caregiver training program was developed based on Progressively Lowered Stress Threshold (PLST) model and gerontological and psychiatric literature. The mean scores of aggressive behavior at baseline, Post I, and II did not differ significantly although the difference approached to the significant level (F = 2.925, p = .066). Nursing staff's aggressive behavior management skills increased at Post I, and at Post II when compared to baseline, and the difference was significant (F=12.736, p=<.00l). Conclusion. Caregiver training program showed potential impact on reduction of aggressive behavior in elders with cognitive impairment and was effective in increasing nursing staff's aggressive behavior management skills.

In this study, we investigated the effects of mixing on the aggressive behavior of commercially housed pigs. The behavioral patterns of 36 groups of pigs (a total of 360 animals) were observed over 3 consecutive days directly after weaning ($25{\pm}1.2$ days of age), and 25 and 50 days later with the aid of video technology. Fight latency and total duration and frequency of fighting were significantly different among the age groups. The aggressive behaviors decreased in 75-day old pigs if compared to 25- and 50-day old animals. Moreover, dominance index (DI) was higher in 25-day old and lower in 75-day old pigs. A comparison of dominant (DI>0) and submissive (DI<0) pigs showed significant differences (p<0.05) for major aggressive behaviors in all age groups. Dominant pigs were involved in more aggressive interactions, had longer fights, and initiated more fights than submissive pigs. Post-mixing aggressive behavior was altered by previous experience of mixing. Aggressive behavior and DI are suitable methods for analyzing the effects of mixing on commercially housed growing pigs.

Providing care to the dementia elderly with behavioral problem is a major issue in nursing homes today. This study was aimed to explore the nursing staffs′ response to aggressive dementia patients, and the effect that the aggressive behavior had on Nsgstaff. The interviews used a semi-structured questionnaire are were carried out from May to July, 1999. The subjects were 23 nursing personnel working in the nursing homes for dementia elderly. The result are as follows; 1. The types of aggressive behavior cited by the subjects was "physical", "linguistic", and "sexual". 2. The factors that caused the behavior were "symptoms of disease", "under- conditioning", "context of nursing care", "unsatisfied need", "relationship to other patients", "change of outer environment", and "invasion of one′s own privacy". 3. The response of the subjects were "unhappiness", "stress", "anger", "exaggeration", "anxiety", and "fear". 4. The management strategies listed by nursing personnel used to alleviate aggressive behavior were "ignorance" "patience" "leaving the area" "soothing sounds" "verbal punishment" "restriction and isolation" and "various management skill appliance" "adaptation". 5. The effect that aggressive behavior and were "disturbance of relationship to elderly" "decline in the amount and quality of nursing care" "interruption of task performance" "job exhaustion" "desire to leave the job" "physical impact" "stress on the cognition of others" "anxiety about health and one own future" "interference to family life′. The findings of this study will be useful in understanding the difficulties of nursing personnel when confronting the aggressive behavior of dementia partients. It also is useful as basic data in preparing efficient intervention program for these difficulties.

Recent analysis results with realistic assumptions provide the variability of operator allowable time for the initiation of aggressive cooldown under small break loss of coolant accident or steam generator tube rupture with total failure of high pressure safety injection. We investigated how plant risk may vary depending on the variability of operators' failure probability of timely initiation of aggressive cooldown. Using a probabilistic safety assessment model of a nuclear power plant, we showed that plant risks had a linear relation with the failure probability of aggressive cooldown and could be reduced by up to 10% as aggressive cooldown is more reliably performed. For individual accident management, we found that core damage potential could be gradually reduced by up to 40.49% and 63.84% after a small break loss of coolant accident or a steam generator tube rupture, respectively. Based on the importance of timely initiation of aggressive cooldown by main control room operators within the success criteria, implications for improvement of emergency operating procedures are discussed. We recommend conducting further detailed analyses of aggressive cooldown, commensurate with its importance in reducing risks in nuclear power plants.

This study investigated moral judgment and moral reasoning about aggressive behavior by intention, presentation of results of aggressive behavior, and age of child. Forty-four 3-year old and forty-six 5-year-old day-care children in Seoul and Kyonggi Province were interviewed individually with 20 pictorial tasks. Data analysis was by frequencies, percentiles, means, standard deviations, paired t-test, and ANOVA(repeated measures). Both age groups judged instrumental and resentment-based types of aggression to be worse than prosocial or rule observance-based aggression. Both age groups judged aggressive behavior to be worse when results of aggression were presented. Five-year-olds judged aggression to be worse on instrumental than on retributive types of intent. Level of reasoning on aggressive behavior was lowest in cases of satisfying resentment Level of reasoning about aggression increased with age.
