In order to evaluate the efficacy and safety of risperidone, 10 patients with chronic schizophrenia were examined for 8 weeks in a silgle-open study. After the wash-out period of 1 week, risperidone was administered. Efficacy was evaluated by means of Positive and Negative syndrome Scale for Schizophernia(PANSS) and Clinical Global Impression(CGI). Safety assessment included the Extrapyramidal Symptom Rating Scale(ESRS), vital signs, body weight, ECG, and laboratory tests. The results were as follows 1) On the PANSS total score, there was significant improvement of total score after 1 week (P<.05) of administratiom. 2) On the PANSS positive and negative subscal, there were significant improvement of posotive and negative scores after 2 weeks (P<.05) of administration. 3) On the PANSS general psychopatholgy subscals, there were significant improvement of general psychopathologyscores after 1 week (P<.05) of administratiom. 4) On the CGI, there was significant decreasement of clinical impression of severity of schizophrenia score after 2 week (P<.05) of administration. 5) A statistically significant increase in body weight (P<.05) was observed after 8 weeks of administration. 6) EPS reached the peak at the end of the 1st week of administration of risperidone (11.8± 24.25) but they were easily relieved by addition of benztropine and clonazepam. There was not significant change in laboratory tests, vital sign, ECG after 8 weeks of administration. These results suggest that Risperidone is an effective antipsychotics and clinically safe except for increased body weight in chronic schizophrenia.

Background: High risks of fire alway exist for buildings in urban areas, especially those in downtown. Crowds, as well as more complex and larger structures, may cause more victims in the event of fire; therefore, emergency medical service plans must be established for such disastrous events. Methods: On the evening of October 30,1999, a fire broke out in downtown, Dong-Incheon Live-Hof restaurant; 56 people were killed and 76 were injured. Most of them were teenagers. We retrospectively reviewed the medical records of the victims, Results: 1) Among the 56 dead, 54 died from smoke inhalation, one from extensive burns, and one from sepsis during treatment. 2) Among the 76 injured, 70 patients suffered from smoke inhalation, 53 from burns, and 9 from several types of trauma (sprains, contusions, lacerations, abrasions, fractures, etc.). 3) Later complications were laryngeal edema, pulmonary edema, scar contracture, and hypoxic brain damage, and so forth. 4) Post traumatic stress syndrome was unexpectedly more prevalent in mildly to moderately injured survivors and witnesses than in seriously injured survivors. Conclusion: Many complications exist after a fire. Some may be resolved in time, but others may result in permanent sequelae. Early rescue, early triage, and early management during transport by emergency medical service (EMS) personnel can result in fewer complications and a lower mortality rate. Therefore, we propose the establishment of plans to be followed during various major disasters.

Three different treatments for induction of estrus in Korean native black goats were compared: follicle stimulating hormone(FSH, FSH-p^TM), FSH combined with MAP(intravaginal impregnated sponges, Veramix^ⓡ, containing 60 ㎎ medroxy progesterone acetate for 14 days), and FSH combined with progesterone(Ovaron^ⓡ, 10 ㎎ IM for 10 days) and PGF_2α(Lutalyse^ⓡ, 3 ㎎ IM at first FSH injection). FSH for inducing estrus and superovulation was given a total 20 ㎎ intramuscularilly in decreasing dosage injections twice daily over 4 days. The MAPs were withdrawn at the 3rd day of FSH injection. Estrus observations were conducted every 6 hours from last FSH injection for 24 hours by placing the does with fertile male goats. Estrus and superovulation were more successfully induced with treatment of MAP + FSH than other treatments(FSH only, or progesterone + PGF_2α + FSH) (estrus induction; 100 vs 42.8 and 71.4%, ovulation points; 11.4 vs 5.4 and 4.4, respectively). The effect of gonadotropin releasing hormone(GnRH) on the ovulation rate was also examined. However, no difference was observed for inducing ovulation with treatment or dosage(100 ㎍ 200 ㎍) of GnRH. Low midline laparotomies were performed, and then ovarian responses (ovulations and follicular development) were examined by exteriorization of the reproductive tracts. Ova were recovered from oviducts by retrograde flushing 60-146 hours after MAP removal, and were classified the developmental stages. Overall 66.1% (236/357) of recovery rate was obtained from 30 superovulated does. The optimal recovery time of microinjectable 1-cell zygotes was approximately 72-76 hours after MAP removal.

To find out the effect of different pollen sources on the fruit setting and the characteristics in the 'Fuji' apple and 'Okusankichi' pear cultivar, this study was carried out by making the self-and cross-pollination using 8 commercial apple and pear cultivars as pollinizers, respectively. The results are summarized as follows: 1. When self-pollinated, most of varieties examined had low setting per cent of fruits, while 'Megumi' showed an extraordinary 33.5% of high self-fruitfulness. There were a few seeds in most self-pollinated fruits, and its fruit size was small compared with cross-pollinated ones. 2. For the fruit setting per cent, no significant advantage could be attributed to anyone over another as pollinizer for 'Fuji' except 'Sekaiichi' and 'Tsugaru.' 3. The weight of fruit pollinated by 'Spur Earliblaze' was decreased as compared with another. 4. No difference of fruit quality could be found out in the cross-pollinated fruits of 'Fuji' apple. 5. In the 'Okusankichi' pollinations, no significant advantage in fruit setting could be attributed to anyone. 6. 'Tsuri' and Hosui' set significantly larger and oblong fruits than open-pollinated ones. The differences of fruit shape index (length/diameter) in each cross-pollinated fruits may be due to the ability of certain pollen to produce seed rather than metaxenia. 7. Possible effects of metaxenia such as color and fruit quality could not be found in the cross-pollinated fruits of 'Okusankichi'. 8. There was negative correlation between number of seed and fruit shape index (length/diameter) in 'Okusankichi' pear, while no consistent correlation of number of seed and fruit shape index could be found in 'Fuji' apple.

The present study has quantitatively assessed the regional production, income and employment impact resulting from the construction and operation of nuclear power plant (NPP) upon the domestic local areas by applying the regional input-output analysis model to the case of Wolsong unit-1 site. The conclusions regarding the most likely regional economic impacts upon the wolsong site are summarized as follows; 1. The income multipliers are calculated to be 1.563 for the construction phase and 1.506 for the operation phase. These values are relatively high compared with those of other conventional facilities. 2. The level of total employee's wage induced employment associated with the construction phase has been estimated to be 37,000 while that with the operational phase in 1990 to be 5,610. 3. With relation to the aspect of resident welfare it is found that the industrial sector associated with electricity, gas and water supply have remarkably improved with the construction of the NPP. 4. The NPP siting has induced substantial changes in interindustry (input-output) structures of the Wolsong unit-1 site which is one of the rural areas where all the domestic NPPs are sited. Such changes are attributed to the industrial recomposition of the region. 5. With the application of other regional economic analysis models and the use of more sufficient regional data, other detailed studies on the economic impact analysis of domestic NPP-related facility sitings are suggested to be carried out further since the influence of NPP sitings is significant to the national economic impact as well as the regional economic impact.

Background : Congestive heart failure after acute myocardial infarction relate to left ventricular systolic sysfunction. Also, left ventricular diastolic function contribute to heart failure. The aims of this study were, firstly to characterize left ventricular diastolic function by transmitral flow velocity, and secondly to study the significance of Doppler measurements in relation to the development of heart failure in the early phase of myocardial infarction. Method : Pulsed Doppler echocardiography of transmitral flow was assessed in 34 patients with acute myocardial infarction. According to the Doppler transmitral flwo velocity profile, the study patients were assigned to the three groups: normal filling pattern (DT > 140ms, IVRT < 100ms), relaxation abnormality (DT > 140ms, IVRT ≥ 100ms), pseudonormal or restrictive pattern (DT ≤ 140ms). Also, on the basis of the presence of heart failure during first week of hospitalization, the patients were divided into two groups: patients with no sign of heart failure (Killip class Ⅰ) and heart failure (Killip class Ⅱ-Ⅳ). Results : Of the 34 patients studied, 10(29%) were normal filling pattern, 17(50%) abnormal relaxation and 7(21%) were restrictive patterns. The left ventricular ejection fraction(EF, 40 ±6%) of restrictive pattern was significantly lower than that of normal filling pattern of abnormal relaxation(p < 0.01). And, the IVRT, DT, E/A and left ventricular EF were reduced in patients with heart failure(14 patients) compared to no sign of heart failure(20 patients)(p<0.05). Of the patients with heart failure, IVRT and left ventricular EF were reduced in patients with DT≤140 ms compared to DT> 140ms(p=0.001). Conclusion : Left ventricular diastolic dysfunction is present early after onset of symptoms of acute myocardial infarction. Assessment of left ventricular diastolic function complements measurements of systolic function in the evaluation of cardiac function. DT, IVRT, E/A and left ventricular EF are useful predictors for development of congestive heart failure following acute myocardial infarction.

A novel bidirectional magnetic micro actuator using a permanent magnet and micromachined silicon mirror has been designed, fabricated and characterized in this work. To realize a bidirectional microactuator, two permanent magnets having opposite magnetical direction each other were bonded onto the silicon mirror. A prototype bidirectional magnetic microactuator has been realized by integrating an electromagnet with the silicon mirror, which has permanent magnets on its backside. By applying a dc current of 1000 mA and altering its polarity, bidirectional motion on the tip of the mirror has been successfully achieved in the deflection range of 420 μm.
