The purpose of this article is analyzing the economic impacts of abnormal climate on fall chinese cabbage farmers and consumers in Korea, with employing the equilibrium displacement model. Our results show that there were little difference in gross farm income, even though there were significant yield reductions due to abnormal climate changes. However periodic occurrences of abnormal climates caused serious damage to consumption levels which had declined by 10.6~17.1 percent with higher prices by 15.3~24.6 percent than normal climate years since 1990.

Background and Objectives : Chronic suppurative otitis media is one of the frequent diseases in otolaryngologic field. It is important to choose of antibiotics in the management of infectious disease. But the organisms in infections have been changed and resistance to antibiotics has been grown as the development of antibiotics has been achieved. And so it has been necessary to recognize the changes of organisms and resistance in antibiotics. Our study was performed to identify the pathogens isolated from discharges in chronic otitis media and evaluate the antibiotic agents, to recognize the change of to resistance to·antibiotic agents and to use the appropriate anitiotics. Materials and Methods : Retrospectively, authors reviewed the backeriologic study of 114 cases of chronic suppurative otitis media who visited the Department of Otolaryngology, Soonchunhyang University in Seoul from Nov. 1996 to Oct. 1999 and analyzed 101 strains and its sensitivity test to various antibiotics. Result : In 93 cases in which pathogenic organism was isolated, single infection was 85 cases(91.4%) and mixed infection was 8 cases(8.6%). The most frequent pathogenic organism was Staphylococcus aureus(59.4%), Pseudomonas aeruginosa(13.9%), Providencia(4.8%), Alcaligenes(3.0%) and Streptococcus pneumoniae(2.9%) were the next. Methicilline-Resistance Staphylococcus aureus was 34 cases(57.6%) of Staphylococcus aureus. Staphylococcus aureus was sensitive to Vancomycin(96.7%), Trimethoprim-Sulfamethoxazole (57.6%), Cefuroxime(42.4%) and Ciprofloxacin(40.7%) but resistant to Penicillin(94.9%). Pseudomonas aeruginosa was sentitive Amikacin(100%), Ciprofloxacin(100%) and Gentamicin(67%). Conclusion : As MRSA recently was wide spread in community accquired infection as well as nosocomial infection, we must consider strict control of MRSA.

Objectives: There is little information on the imbalance of electrolyte and acid-base metabolism associated with gastric lavage in acute drug intoxication patients. This study was aimed to analyze the acid-base and electrolyte abnormalities associated with gastric lavage in acute drug intoxication patients. Methods: We studied 24 acute drug intoxication patients who had performed gastric lavage with 10 liters of 0.9% NaC1. Electrolyte parameters and arterial blood gas analysis were carried out before and after gastric lavage. Results: After gastric lavage, acidosis was reduced in general. But there was no significant change in pH (7.34±0.02 vs. 7.38±0.15, p=NS). In acid-base balance, the mixed form of metabolic acidosis and respiratory acidosis was reduced from 7 to 2 cases, and the simple form of respiratory acidosis was reduced from 3 to 1 case. In contrast, normal form was increased from 5 to 7 cases and the simple form of metabolic acidosis was increased from 2 to 6 cases. In electrolyte parameters, serum sodium was reduced significantly (145±1.0 mEq/L vs. 141±0.8 mEq/L, p<0.01), but there was no case of significant hyponatremia (<135mEq/L). Bicarbonate level (20±1.1 mEq/L vs. 22±0.9 mEq/L, p< 0.05) and anion gap (19±1.6 mB vs. 13±1.3 mEq/L, p< 0.01) showed significant change. But, blood levels of potassium (3.6±0.1 mEq/L vs. 3.8±0.1 mEq/L, p=NS), chloride (106±0.6 mEq/L vs. 106±0.6 mEq/L, p=NS) and F'aCO2 (36±1.mmHg vs. 37±1.5 mmHg, p=NS) were no significant change before and after gastric lavage. Conclusions: Gastric lavage with 10 liters of 0.9% NaC1 in acute drug intoxication patients did not show clinically significant changes in electrolytes and acid-base balance.

Background: Many patients with gastrointestinal bleeding show anemia and usually need red blood cell transfusion. But clinicians are concerned about low hemoglobin affects prognosis and clinical outcome after discharge. This study aimed to assess whether discharge hemoglobin infi uence on outcomes, or not, in patient with acute non-variceal gastrointestinal bleeding. Methods: Retrospective analysis was carried out on patients who had upper gastrointestinal bleeding between January 2011 and December 2012. We analyzed the patients who had lowest hemoglobin below 10 g/dL during hospitalization. Patients with variceal bleeding, stroke, or cardiovascular disease were excluded. We divided the patients into two groups by discharge hemoglobin (Low discharge hemoglobin group; 8 g/dL = hemoglobin and compared clinical outcomes and hemoglobin level changes. Results: A total of 212 patients with upper gastrointestinal bleeding were undergone the endoscopic hemostasis during study periods. One hundred two patients were satisfi ed the inclusion criteria. fifty patients discharged with hemoglobin level under 10 g/dL and fi fty two patients discharged with hemoglobin level over 10 g/dL. Patients in low discharge hemoglobin group showed a lower consumption of pRBC and shorter hospital days than patients in high discharge hemoglobin group. Hemoglobin levelswere not fully recovered at out-patient department until 7 days after discharge. But, most patients showed hemoglobin recovery at 45 days after discharge.Conclusions: In patients with acute gastrointestinal bleeding, discharge hemoglobin between 8 to 10 g/dL was showed favorable outcomes during out-patient department follow-up. It seems to be tolerable level without additional pRBC transfusion. Our result can increase the evidence available to support restrictive transfusion strategies in patients with acute non-variceal upper gastrointestinal bleeding.

A simplified procedure is described for screening swine urine for the presence of sulfonamides residues. The principle of method is synergism and antagonism of sulfonamide. When sulfonamide is combined with trimetoprim(TMP), antibacterial synergism is obtained. On the other hand, when excess p-aminobenzoic acid(PABA) is present the antibacterial activity of the sulfonamides is overcome. THe method involved soaking two discs into pork urine. Each disc is placed on couple of test plates using EEC-four plate inoculated with Bacilus subtilis spore at pH 7.2. One plate is incorporated with TMP(TMP-plate), another is PABA(PABA-plate). Diffusion of an antibacterial substance is shown by the formation of ones of inhibition(inhibition zone). Particularly either the inhibition zone on TMP-plate only or much greater inhibition zone on TMP-plate than PABA-plate considers good evidence to send the specimen for specific sulfonamide residues test. Of a total 220 urine samples tested by this screening method, 63 cases were showed the inhibition zones. Among them inhibition zones were only shown on TMP-plate in 12 cases and inhibition zones on TMP-plate were much greater than PABA-plate in 8 cases. Accompanied with the microbioassay, thin-layer chromatographic(TLC) tests for screening the sulfonamide residues with Sulfa-On-Site(SOS) kit were applied to same samples in which two positive cases were shown . The sulfamethazine residues in 2 TLC positive urine were identified by high performance liquid chromatographic(HPLC) test. One TLC positive urine is one of 12 cases in which inhibition zones on TMP-plate were only shown and another TLC positive urine was also included in much greater inhibition zones on TMP-plate cases. With this result, the possibility of screening the sulfonamide residues in swine urine by this microbioassay is obtained.

The paper was attempted to figure out the effects of the visual and music theraphy on the variables of zerobic exercise capacity during submaximal exercise load running on treadmill(LE-5, Jaeger, Germany). To achieve the goal, the 30 music-loving(pop and rock music) female university students among 160 students of physical education deaprtment in S university were selected as subjects for experiment, and were randomly devided into three groups: 1) Exercise Stimulation group(10 subjects)- were stimulated only by treadmill submaximal load running exercise(9km/h, 3% permanently), 2)Music Theraphy group(10)- were stimulated by background music(pop and rock music) through cassette tape recorder during treamill submaximal load running exercise, 3)Visual Theraphy group(10)- were stimulated by video program (SKI Attitude: KED Limited)through exercise. The item of aerobic capacity test were HR, BF, VE, VO2, VCO2(analyzed by EOS-sprint, Jaeger, Germany). Test phase were atatic state and 6, 12 min, all-out during treadmill load test), and 5, 12min of recovery phase by EOS-sprint. The conclusions are as follows: 1. HR value of music and visual theraphy group at 6min in the submaximal load exercise were slightly lower than exercise stimulation group. AT 12min and all-out time the HR value of visual group were lower than another two groups. but exercise group's HR were lower than that of any other groups at 5min of recovery. But that of visual theraphy group were lower than another two groups at 10min of recovery(between groups: p<0.001, between checking time : p < 0.001). 2. BF value of visual and auditory groups were higher than that of exercise group. And at 12min, that of auditory's were lower than other's. At all-out time, that of auditory and visual stimulation gruops were lower than that of exercise stimulation groups. and auditory stimulation groups was lower than that of other group's in 10min of recovery(between groups: p<0.001, between checking times: p<0.001). 3. VE value of auditory stimulation group at 6min, 12min and all-out time, exercise was higher than that of visual and exercise stimulation group. That of auditorial group in the 5min of recovery was lower than that of exercise and visual stimulation group, but exercise group's VE value was lower than that of any other groups at 5min of recovery. And that of visual theraphy group was lower than that of any other groups(between groups: p<0.001, between blood sampling time:p>0.05). 4. VO₂value of visual stimulation group was higher than that of anthor two groups at 6min, 12min and all-out time. At 5min of recovery, that of music theraphy group was higher than of other two groups. That of visual theraphy group was lower than that of another two groups at 10min in the recovery(between groups: p<0.001, between checking times : p<0.001). 5. VCO₂value was not effected by three stimulations and every checking time(between groups: p>0.05, between checking times: p>0.05).
