As the modern society is called the narcissistic society, the narcissism is widespread in the personality of individuals and the society at large. In consideration of this side, this study explored for several characteristics of the narcissistic personality and the job stress, and explored for the relationships between the two things theoretically. The narcissism is an attempt to repair self-esteem weakened by the splitting anxiety, the lack and the pathological fusion of self-structure. The job stress is a factor that a characteristic of the job influenced on the behavioral and affective response of the person on the job directly or indirectly. This study selected organizational justices, organizational constraints, role conflict, role ambiguity, role overload, organizational climate, interpersonal relations and career development as factors of the job stress. This study viewed that the stress is made from an interaction between environmental stimulus and personal particular reaction by defining the stress as an interaction model of stimulus-response and personal reaction is caused by psychological adjustment process, personal differences. On this occasion, this study discussed that the narcissistic personality is easy to get stress and weak in the job stress with regarding the personality as a mediation variation of psychological process. As a result, the narcissists estimated themselves positively and their self-esteem is high, but they excessively showed a self biased cognitive and affective response about the negative feedback to protect themselves. Moreover, this positive estimate on themselves and high self-esteem was vulnerable and weak in the self threat. In this view, the narcissistic personality is easy to get more job stress such as organizational justices, organizational constraints, role conflict, role ambiguity, role overload, organizational climate, interpersonal relations and career development.

Safety issue for offshore wind-turbine foundation becomes a crucial factor as offshore wind turbines have been scaled up. Correspondingly, there is a demand to understand the effect of soil-structure interaction on to system behavior in geotechnical engineering point of view. The p-y curve method researched in past few decades is one of the most appropriate methodology to analyze the problem. In this study, recently proposed p-y curve models for various rocks are calibrated to analyze the engineering characteristics of seabed of Jeju Island where it is known to be most suitable area for offshore wind energy farm. Step by step calibration process for p-y models is presented. Analysis results show that subgrade reaction generally increases as closer to seabed. It is also shown that the behavioral characteristics of foundation reflect well rock properties in terms of resultant moment, shear force, etc.

As the intense heat continues, many cases of highway pavement blow up and bridge expansion joints damages have been inspected. Especially, Expansion joint closure of bridges is an important problem that can threat the safety of the bridge structure or reduce long-term durability. This paper proposed a structural analysis method for bridges having expansion joint closure and structural analysis was performed to verify the effects according to bridge types. Analysis bridges were divided into four types: concrete and steel bridges, shallow and piled foundations. To induce the situation of abutments and bridge decks are jammed, the following loads were additionally considered; lateral flow pressure, pavement expansion by alkali-aggregate reaction, creep settlement of backfill. The structural analysis method was verified by comparing the structural analysis results with the actually measured joint gap data. In addition, behavioral analysis due to joint closure was conducted to confirm the change in safety ratio by type of superstructure as the axial force increased.

There are several candidate genes in genetic study of alcoholism. Among them, allelic associations have been reported between MAOA CA repeat polymorphism and alcohol dependence, recently. And also, several studies have been investigated genotype-phenotype relationships between MAOA CA repeat polymorphism and clinical manifestations. The authors tried to identify differences in allelic frequency of MAOA CA repeat polymorphism between alcohol dependence and controls, and in behavioral trait and clinical characteristics according to MAOA CA repeat polymorphism. We also tried to investigate genotype-phenotype relationships between MAOA CA repeat polymorphism and behavioral trait such as aggression. We examined 49 male patients with alcohol dependence(DSM-IV) who had been admitted in Yong-In Mental Hospital from June 1st 1998 to October 31th 1998. We performed semistructured interview for demographic and clinical characteristics. Self-report questionnaire for BDHI(Buss-Durkey Hostility Inventory) was given to all subject at least 4weeks later after admission. Using polymerase chain reaction and polyacrylamide gel electrophoresis, MAOA CA repeat polymorphism were observed in 52 male controls and 49 male patients with alcohol dependence. We devided alcoholic patients into two groups according to allelic length of MAOA CA repeat polymorphism ; alcoholics with short alleles(${\leq}$119bp, N=20) and alcoholics with long alleles(${\geq}$123bp, N=29). T-test, ${\chi}^2$-test and Fisher exact probability test were used for statistical analysis. There were no significant differences in frequency of each allele and short and long alleles of MAOA CA repeat polymorphism between alcoholics and controls. But there were significant differences in clinical symptoms and behavioral trait between alcoholics with short and long alleles. In clinical symptoms, alcoholics with long alleles used alcohol more frequently during one month before admission, had much more maximum amount of beer drinking and reported withdrawal seizure more frequently than with short alleles. In contrary, alcoholics with short alleles expressed depressed mood and guilty feeling more frequently and wanted complete abstinence as a treatment goal more frequently than with long alleles. In behavioral trait, alcoholics with long alleles had higher total aggression score and showed much more self-assertive attitude(subscale of expression of aggression) than with short alleles. Allelic length of MAOA CA repeat polymorphism was correlated with self-assertive attitude and accounted for 9% of the variance of self-assertive attitude. And also, predictable variables of allelic length of MAOA CA repeat polymorphism were drinking frequency and self-assertive attitude. Our findings suggest that MAOA CA repeat polymorphism may provide some behavior modifying role especially in self-assertive attitude and indirect symptom modifying role in Korean male alcoholics.

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.

Driving involves a series of complicated precesses requiring various human capacities, such as perception, will decision, and athletic functions. Consequently, it induces a high degree of continuous concentration of mind and tension from external stimulation, bringing fatigue to the driver, and driver fatigue is counted as one of the major causes of traffic accidents. Nevertheless, because of the complicated urban lives, traffic congestion, job characteristics, and so on, the drivers have to spend a longer time inside a vehicle, and the fatigue and stress thereof is almost unavoidable. We haute, therefore, turned our attention to the reduction in the fatigue during driving by supplying oxygen, and investigated in this research the drivers subjective fatigue evaluations and reaction time when oxygen is supplied in different rates. As a result, we have found that the subjective fatigue feeling is highest at low-rate O/Sub 2/ supply (18%), and fatigue feeling was comparatively reduced at high-rate O/Sub 2/ (30%). The sleepiness also showed the tendency to be reduced at high-rate O/Sub 2/ supply in the case of driving for 1 hour or more. The time for reaction to braking after the sign for urgent stop is given tends to show more substantial reduction at high-rate O/Sub 2/ supply than at low-rate O/Sub 2/ supply after 2 hours driving. It can, therefore, be deduced from the aforesaid results that the subjective responses and behavioral reactions tend to show reduced fatigue at the condition of high-rate O/Sub 2/ supply. Hence, it was suggested that drivers felt subjective fatigue while driving at low-rate O/Sub 2/ and the subjective fatigue and reaction time were reduced at high-rate O/Sub 2/. These findings suggest that the oxygen supply will reduce driver fatigue.

Objective: This study analyzed mother-child interactions in a stressful situation each second by mother's emotional regulation level. Methods: The study was conducted with 16 mothers and their 5-year-old children playing a teaching task for 15 min. During the interactions, the participants were videotaped and examined. Furthermore, qualitative analysis was used for analyzing mother-child interactions in detail by creating a situation that maximizes the stress and frustration of the mother and child. Results: The results showed that maternal humor and affection were significantly related to child positive emotion and that maternal coaching closely correlated with the child pride, pleasure, and whining. Additionally, maternal intrusive behavior showed a positive correlation with child anger. Lastly, mothers with higher levels of emotional regulation more often expressed affection to their children. They were more actively involved in the tasks and used fewer positive or negative directive expressions. Therefore, children of this group expressed more positive emotions. Conclusion: These findings suggests that programs improving parental emotional reaction and emotion regulation should be developed.

Purpose: This study was to delineate the structural change of neural pathway after sequential motor learning using diffusion tensor imaging (DTI). Methods: The participants were 16 healthy subjects, which were divided by training (n=8) and control (n=8) group. The task for the training was the Serial Reaction Time Task (SRTT) which was designed by Superlab program. When the 'asterisk' shows up in the 4 partition spaces on the monitor, the subject presses the correct response button as soon as possible. The training group participated in the training program of motor learning with SRTT composed of 24 digits pattern in one hour per daily through 10 days during 2 weeks. Results: In the behavioral results the training group showed significant changes in the increase of response number and the reduction of response time than those of the control group. There was significant difference in the left inferior frontal area in the fractional anisotropy (FA) map of the training group in DTI analysis. Conclusion: Motor sequential learning as like SRTT may be needed to the learning of language and visuospatial processing and may be induced for the experience-dependent structural plasticity during short period.
