It is very critical to promptly maintain airway of cardiac arrest cases or serious traumatic cases. The purpose of this study is to compare intubation rate, successful rate and pre-/post-education self-confidence between laryngeal tube (LTS) and proseal laryngeal mask (PLMA), so that it may contribute to improving the ability of 119 emergency team - a pivotal role in pre-hospitalization process - to carry out advanced airway management. In order to achieve the purpose, total 60 paramedics (Class I) who worked for incumbent 119 emergency team were asked to join a practical experiment and were also divided into two groups (LTS group: 30 people, PLMA group: 30 people). In details, they were all asked to take 3 sessions of practice (5 minutes per session) using dummy model to quantitatively measure the time and success/failure of intubation and the change of their self-confidence. As a result, it was found that there were statistically significant differences in the time of intubation between LTS and PLMA group (p=.000), but there was no significant difference in the rate of successful intubation between these two groups, and self-confidence of two groups tended to significantly increase after experiment (p=.000). Conclusively, if it is necessary to promptly apply intubation to traumatic cases with immobilized cervical vertebral and lingual edema, LTS can be useful as an effective means of intubation. And it is expected that continuing intubation training using LTS will improve the ability of emergency team to perform advanced airway management for traumatic cases.

Imidapril(Tanatril$^{(R)}$), a newly developed ACE inhibitor, has been used to treat hypertension and congestive heart failure. This study was designed to assess the antihypertensive effect and safety of Imidapril(Tanatril$^{(R)}$) in patients with essential hypertension. 5-10mg of imidapril(Tanatril$^{(R)}$) was administered once a day in 30 patients with essential hypertension and followed up for 8 weeks. We tested the drug's effectiveness, safety, and the incidence of imidapril induced dry coughs. After 8 weeks of treatment with imidapril, 76.2%(16/21) of patients showed lowered blood pressure and 47.6% showed normal blood pressure. The overall incidence of adverse effects was 33.3%(7/21), and among these adverse effects, dry cough was shown in only 9.5%. Thus, we concluded that imidapril(Tanatril$^{(R)}$) is as safe and effective as other ACE inhibitors, especially with imidapril showing very little incidence of dry cough compared to other ACE inhibitors.

Purpose : Refractory status epilepticus(RSE) is a serious neurological emergency in children. The mortality is high and the neurological outcome is not good. This study aimed to evaluate the clinical significance of cerebrospinal fluid(CSF) pleocytosis in refractory status epilepticus in children. Methods : From January 1999 to January 2006, 25 out of 37 children with refractory status epilepticus had spinal tapping. We retrospectively analyzed the data from these children's medical records. We compared the results between groups with and without CSF pleocytosis, and between a group with first seizure and a group with epilepsy. Result : Six out of 25 children had CSF pleocytosis. The group without CSF pleocytosis had a higher mortality rate and required higher doses of antiepileptic drugs as compared with the group with CSF pleocytosis. The group with CSF pleocytosis had much worse neurologic segualae. However, except for the children with CNS infection, the overall prognosis between the group with and without CSF pleocytosis was not significantly different. All children with CSF pleocytosis came in with first seizures. Conclusion : In children with RSE, a CSF study must be perfomed as soon as possible to exclude the possibility of CNS infection. A CSF study is even more important in cases of first seizure or CNS infection suspected. Mild CSF pleocytosis without evidence of infection does not seem to affect the prognosis, so physicians should therefore be more cautious in selecting antibacterial or antiviral agents for it.

Purpose : Several methods of IV ${\gamma}-globulin$(IVG) infusion are effective in the treatment of autoimmune disease, including idiopathic thrombocytopenic purpura(ITP). But it is not known which method is more effective in the treatment of ITP. The effectiveness of these two methods of IVG infusion was studied in terms of platelet recovery rate, side effects and recurrence rate. Methods : Forty seven patients with acute ITP in the department of pediatrics, Eulji University Hospital from January 1995 to June 2001 were enrolled. We assesssed the treatment effects of 47 patients blindly selected; IV ${\gamma}-globulin$ 2 g/kg/day in one day(treatment group A, n=25), 400 mg/kg/day in five days(treatment group B, n=22). Results : Treatment group A increased platelet count more rapidly on the 2nd, 4th and 6th day of treatment than treatment group B. Side effects like fever, chill and vomiting were more frequent in treatment group A than treatment group B. The platelet count on the sixth day of treatment showed a greater increase in the cases which had side effects than in the cases which did not. There was no difference between the two groups in the recurrence rate. Conclusion : IV ${\gamma}-globulin$ 2 g/kg/day in one day increases platelet count more rapidly than 400 mg/kg/day in five days, and is favorable for the prevention of a severe hemorrhagic episode like early intracranial hemorrhage.

Objectives : The management of massive brain swelling remains an unsolved problem in neurosurgical field. Despite newly developed medical and pharmacological therapy, the mortality and morbidity due to massive brain swelling remains high. According to many recent reports, surgical decompression with dura expansion is superior to medical management in patients with massive brain swelling. We performed surgical treatment on the first line of treatment, and followed medical management in case with refractory increased intracranial pressure(ICP). To show the quantitative effect of decompressive surgery on the intracranial pressure, we performed ventricular puncture and checked the ventricular ICP continuously during the decompressive surgery and postoperative period. Materials and Methods : Fifty-one patients with massive brain swelling, undergoing bilateral decompressive craniectomy with dura expansion, were studied in this study. In all patients, ventricular puncture was performed at Kocher's point on the opposite side of massive brain swelling. The ventricular pressure was monitored continuously, during the bilateral decompression procedures and postoperative period. Results : The initial ventricular ICP were varied from 13mmHg to 112mmHg. Immediately after the bilateral craniectomy, mean ventricular ICP decreased to $53.1{\pm}15.8%$ of the initial ICP(ranges from 5mmHg to 87mmHg). Dura opening decreased mean ICP by additional 36.7% and made the ventricular pressure $16.4{\pm}10.5%$ of the initial pressure (ranges from 0mmHg to 28mmHg). Postoperatively, ventricular pressure was lowered to $20.2{\pm}22.6%$(ranged from 0mmHg to 62.3mmHg) of the initial ICP. The ventricular ICP value during the first 24 hours after decompressive surgery was found to be an important prognostic factor. If ICP was over 35mmHg, the mortality was 100% instead of additional medical(barbiturate coma therapy and hypothermia) treatments. Conclusion : Bilateral decompression with dura expansion is considered an effective therapeutic modality in ICP control. To obtain favorable clinical outcome in patients with massive brain swelling, early decision making on surgical management and proper patient selection are mandatory.

This study was aimed at finding out the relationship between the level of depression and the recognition and attitude of suicide and the study was conducted by a structured and self-filling questionnaire survey for 1,114 urban area students and 968 rural area students (totaled 2,082) in K city in the central districts of the country from July 1, 2009 to July 31, 2009. The result of the study showed that the more serious the level of depression, the higher the recognition and level of attitude for suicide was. Suicide attitude had a meaningful relationship with the degree of suicide recognition and the level of depression and the level of suicide recognition was closely connected with the level of depression. The result of the analysis of Hierarchial multiple regression showed the meaningfully related factors that affect the level of depression were sex, major, grade, school life satisfaction, fellowship with schoolmates, departing from girl or boyfriends, the lowest bracket of living standard, subjective health, smoking, financial status of household, a quarrel with parents and attitude of suicide. In particular, variables that are related to the condition of family life have high relationship with the level of depression.

The purpose of this study was to investigate psychological separation, depression and antidepressive coping behaviors and to examine the relationship between psychological separation, and depression in Korean university students. The subjects were 131 students who were in 4 university in Chungcheong-do, Korea. The data were collected through self reported structured questionnaire using the psychological separation index, beck depression inventory and antidepressive coping behaviors instrument. The level of depression was classified into; not depressed, 54.2%; mildly depressed, 22.9%; moderately depressed, 16.8%; severely depressed, 6.1%. Among antidepressive coping behaviors, cognitive activity-oriented behaviors was the one with highest percentage(30.8%). Depression was negatively related to functional independence, attitudinal independence, emotional independence from father and conflictual independence from mother. And depression was positively related to conflictual independence from father. These results suggest that it is necessary to develop nursing intervention to strengthen psychological separation form parents and to be able to help desirable antidepressive coping behaviors for the psychological health of university students.

Larvae of fishes were collected at 26 stations in the Korea Strait, by horizontal towings using the fish larval net (Norpac) in the surface layer and by oblique towings using Isaac-Kid mid-water trawl in the mid-water layer in summer (July) and in autumn (November), in 1983. The towing speed was 1.5 knots. Of the larval fish examined, 3,529 individuals were identified to generic and specific levels. They belong to 27 families, consisting of 38 species in 37 genera. Unidentified were 114 specimens. The most abundant species was Engraulis japonica which occupied $88.5\%$ of the whole 3,645 individuals. Diaphus sp. took the second place with 50 individuals ($l.3\%$). Seasonally abundant species were in the order of Engraulis japonica, a Gobid, Trichiurus lepturus, and Diaphus sp. in summer, and in the order of Diaphus sp., Engraxlis japonica, Bothus sp., and a Ophichthid in autumn. Of these larvae, Engraulis japonica and Diaphus sp. continuously appeared from summer to Autumn. Champsodon sp., Diaphus sp. and Synagrops philippinensis were unrecorded species in Korea.
