Nowadays, Stress is becoming an increasingly important concern both in individual and in organization. This is because of the tremendrous results which are caused by it. For this reason, diverse research has been done to reduce the harmful results which are most frequently related to stress in organization. But, there has evenly existed no common definition of stress, yet. Thus, after reviewing many literature about stress, we clarified the concept of stress and suggested the necessity of stress management examining aversive effect on both individual and organization. At the same time, in addition to exploring five models relating stressor to stress symptom, we also illustrate stressors on which were commonly emphasized by these models. Based upon th9 theoretical background, we analysed the critical influential factors of stress symptom outcomes through the empirical research. The main findings out of the analysis are as follows: As critical factors of impacting on outcomes, it was indicated that job context stressors such as lack of promotion opportunity and inequality compensation were more important factors than job content stressors such as job variety and job significance. On the other hand, on occasion of physical and mental symptoms, individual factors such as A-personality and self-confidence were the most critical factors to impact on symptoms. In this respect, individual factors were functioned as moderator of relating between stressors and stress symptom outcomes. This tendency was turned out to be more explicit in female. From the preceding analysis, we will give some suggestions for stress management as follows: 1) To set up career planning and developing program. 2) To establish a systematic and equitable reward system. 3) To assign the opportinuity of systematic personality changing. 4) To create a supportive climate and social support. 5) To redesign job. 6) To reduce conflict and clarify roles. This study alas limitation in that it did not fully consider the measurement of stress concept and in that investigating has been conducted in a short Period of time. It is recommended that more systematic researches should be needed through a more careful, detailed observation over long periods of time.

The decompressine surgery via laminoplasty is usually carried out for the symptomatic ossification of posterior longitudinal ligament of the cervical spine. We report a case of temporary hemi - spinal cord injury had after laminoplasty at mid- cervical region. This 55-year old male had bilateral upper extremities numbness and paresthesia and bilateral lower extremities numbness for 3 months before admission. During the walking, he felt "just walking upon the cloud". Plain cervical spine X-ray and cervical spine CT revealed marked continuous type of ossification of posterior longitudinal ligament from the C4 to the C6 vertebral bodies. He underwent laminoplasty especially at left side mid cervical spine. Immediate after surgery, left side motor hemi weakness especially upper extremity was developed with left side surperficial and deep sensory diminishing. Above neurological symptoms were nearly completely recovered 3weeks after operation. We discussed pathoanatomical change after acute spinal cord decompression.

The objective of this study is to find the most effective educational method on Sex and AIDS/HIV among young people in Korea. The number of people with HIV amounts to 1,224 as of Sep. 2000, and is increasing continuously, especially among young people(National Institute of Health, 2000). In setting up the policy of health education on Sex and AIDS, the criteria should be the effectiveness. By two-stage cluster sampling, 4,713 students were selected from among the 19,093 students from 44 middle and high schools and divided into three groups and taken the education with three different methods(〈lecture with slides show〉, 〈lecture without any material〉 and 〈lecture through broadcasting system〉) by the same lecturer with the same contents for about 50 minutes. To compare the effects of education by methods, the tests on the AIDS knowledge, AIDS attitude on AIDS and Sexuality attitudes with self-administered questionnaire were implemented three times, that is, 'before', 'right after' and '2 weeks later' of the education. As to the decrees of change of AIDS knowledge, AIDS attitudes, Sexuality attitudes and subjective evaluation of the education, 〈lecture with slides show〉 was the most effective, 〈lecture without any material〉 was the second and 〈lecture through broadcasting system〉 was the least effective, respectively. In the cost-effectiveness analysis using the results of this study, 〈lecture with slides show〉 turned out to be the most effective, and 〈lecture through broadcasting system〉 was the second and 〈lecture without any material〉 was least effective. From these results, it is suggested that 〈lecture with slides show〉 is more effective health educational methods on Sex and AIDS than 〈lecture without any material〉 or 〈lecture through broadcasting system〉.

Behavioral and neurochemical effects of ethanol were assessed in rats after acute administration. Ethanol, 1-5g/㎏, inhibited the memory and rotarod performance, but significantly increased the spontaneous locomotor activity. Ethanol, 1-5g/㎏, did not affect the striatal dopaminergic neuronal activity and cortical noradrenergic neuronal activity. Ethanol, 1g/㎏, decreased the contents of DA(46.7%), DOPAC(66.7%) and HVA(79.2%) in frontal cortex, but increased the contents of DA(125%), DOPAC(116.7%) and HVA(l40%) in hippocampus. Ethanol, 2-5g/㎏, significantly increased the dopaminergic neuronal activity in frontal cortex, while it remarkably decreased the monoaminergic neuronal activity in hippocampus. These results suggest that the activity of cotical dopaminergic neuron play an important role in modulation of the motot activity induced by low does of ethanol, and that the activity of cotical and hippocampal catecholaminergic neurons could be responsible for the control of memory induced by higher does of ethanol.

The present study was undertaken to elucidate the behavioral characteristics of nootropic candidates, centrophenoxine, N-methyl-D-glucamine, piracetam and red ginseng saponin components on stereotyped sniffing behavior induced by apomorphine in rats. Apomorphine, a direct dopaminergic receptor agonist, induced stereotyped behaviors including sniffing, licking, gnowing and biting in a dose dependent manner, and that behaviors were completely inhibited when measured at 1 week after 6-hydroxydopamine(6-OHDA) treatment. Centrophenoxine, N-methyl-D-glucamine, red ginseng total sapomin (TS), panaxatriol (PT), and Rg_1 enhanced but panaxadiol (PD) inhibited, whereas priacetam and Rb1 were not effective of the stereotyped sniffing behavior induced by apomorphine (1 ㎎/㎏). The enhanced stereotyped behavior by centrophenoxine, N-methyl-D-glucamine, red ginseng total saponin, panaxatriol(PT), and Rg_1 was blocked by pretreatment of 6-OHDA. These results suggest that dopaminergic neuronal activity plays an important role in the action of some nootropic candidates. Red ginseng total saponin, panaxatriol and Rg_1 seems to have a similiarity to centrophenoxine, N-methyl-D-glucamate in modulating of dopaminergic neuronal activity and also may be useful for the nootropic candidates.

Cyclic changes in the fine structure of the oviductal epithelial cells of guinea pig during the estrous cycle were studied by transmission electron microscopy. The results obtained were as follows: 1. The epithelium of the guinea pig oviduct was consist of the ciliated cells and the secretory cells. The former did not show any cyclic changes but the latter did various cyclic changes during the estrous cycle. 2. The secretory cells characterized by well developed Golgi complexes and dilated rough endoplasmic reticulum were showed highly active during proestrous and estrous stage. 3. During metestrous stage, the secretory cells showed most active secretory activity as a number of secretory granules were most abundant and cytoplasmic buldging into the lumen was most conspicuous. 4. The thinner epithelial layer was observed during diestrous stage. And the secretory cells showed several degenerative changes during this stage as they were characterized by decreased microvilli, swollen mitochondria, cytoplamic vacuolation and the appearance of lysosomes.

Effects of the standardized ginseng extract (G115) on the central monoaminergic systems were investigated in comparison with that of haloperidol in rats. Immediately after sacrificed by decapitation, the striata and frontzl cortex were removed. Concentrations of the monoamines dopamine and serotonin and their metabolites were determined by HPLC-EC. G115 increased the concnetration of 5-HIAA and DOPAC/DA ratio in striatum. However, dopaminergic neuronal activities were not affected by G115 that decreased the concentrations of 5-HT and 5 HIAA in frontal cortex. G115 in combination with apomorphine significantly increased the concentration of DA and 5-HT but decreased the DOPAC/DA ratio and 5-HIAA/5-HT ratio only in frontal cortex. These results suggest that G115 like HPD inhibits the activity of nigrostriatal dopamine neuron in striatum. However, unlike HPD it activates central monoaminergic neuron activity in frontal cortex.
