This experiment was conducted to improve light environment of oriental melon cultivation in winter season. Three polyolefin (J-1, J-2 and J-3), two polyethylene (K-1 and K-2) films and K-3 commonly used in farmhouses, with different film thickness, ultraviolet ray interception and infrared ray absorption ratio were used. Heat conservation of J-2 was highest, compare to K-3, J-3 and J-1. Early growth of J-1, J-2 and J-3 were faster than K-3, and Days required to harvest of K-3 were shortened about 10 days. Marketable yield of K-3 was 991kg per 10a, those of J-1, J-2, J-3, K-1 and K-2 were increased 21%, 37%, 24%, 13% and 4% compare to K-3, respectively. Especially, harvesting of J-1, J-2, J-3 and K-1 were focused on early (50%) and middle stage (40%). Polyolefin with higher heat conservation improved growth and harvesting in early and shortened days to harvesting in winter season.

This study was to determine aromatic constituents and essential oil content in the root of Codonopsis lanceolata grown at different altitudes; Andong(150m), Mt. Hagka(550m) and Mt. Irwol(750m). Soil pH in Mt. Hagka and Mt. Irwol was 5.6 and 6.1, respectively, which was lower than in Andong(150m), but organic matter content was higher than that of Andong with 6.7 to 8.8%. Fresh root yield also increased as cultural region was located at higher altitude. In particular, yield in Mt. Irwol was 281kg/10a. Essential oil content was highest of 0.006% in the Mt. Irwo1. Forty-eight volatile aromatic compounds in the root of Codonopsis lanceolata were identified by GC/MS. Major aromatic compounds were 1-hexanol, cis-3-hexano1. and Trans-2-hexanol. In partucular, Trans-2-hexanol, was highest in Mt. Irwol attaining the 47.22% area. As a result, it was considered that cultural region above 700m in altitude was the most effective for the improvement of essential oil and aromatic constituents in the roots of Condonopsis lanceolata Trautv.

To evaluate the values of the thyroid autoantibody measured by radioimmunoassay (RIA) and compare it with hemagglutination method (HA) in the normal and the thyroid disease, data were obtained from total 618 persons; 236 healthy persons, 217 patients with Graves' disease (including 113 patients with undertreated Graves' disease), 100 Hashimoto's disease, 31 thyroid nodule, and 34 simple goiter. RSR kit made in England was used and could be detected to at least 3 U/ml. The positive rates of normal group were antimicrosomal antibody (AMA) 31.8%, antithyroglobulin antibody (ATA) 44.5% by RIA and there was no considerable change in sex and age distribution. In Graves' disease, the positive rates of AMA and ATA were 90.4, 76.9% by RIA, 85, 39% by HA. In Hashimoto's disease, 94,91 % by RIA, and 87,48% by HA, respectively. The autoantibody titer by RIA in thyroid autoimmune disease as well as in normal group was more senisitive than that by HA, especially in ATA. There were linear relationships between the titer of RIA and that of HA in AMA of Graves' disease and AMA and ATA of Hashimoto's disease. There was no relationship among thyroid autoantibody, free $T_4$ index, TBII, and TSH. The titers of AMA and ATA were found to decrease in patients with Graves' disease during the course of antithyroid drug therapy. Of the 236 normal subjects, thirty-seven (15.7%) had concentrations of above 7.5 U/ml in AMA, forty. four (18.6%) above 9 U/ml in ATA. These values were considered as the upper limit for the normal range. In Graves' disease, 82.7, 53.8% were above 7.5, 9 U/ml, respectively; In Hashimoto's disease, 82, 79% were positive. We conclude that RIA was more sensitve than HA in measuring the thyoird autoantibody, but we will study further more for determining the normal range and its interpretation.

Purpose: No consensus currently exists regarding the maximal pressure of hyperbaric oxygen (HBO₂) therapy performed within 24 hours of acute carbon monoxide (CO) poisoning. This study aimed to evaluate the difference in therapeutic effects according to the first HBO₂ pressure (3.0 atmospheres absolute [ATA] vs. 2.8 ATA). Methods: We used prospectively collected registry data on CO poisoning at a tertiary academic hospital in the Republic of Korea. Adult patients with acute CO poisoning treated with HBO₂ within 24 hours after arrival at the emergency department and without the use of additional HBO₂ after 24 hours between January 2007 and February 2022 were included. Data from 595 patients were analyzed using propensity score matching (PSM). Patients with mild (non-intubated) and severe (intubated) poisoning were also compared. Neurocognitive outcomes at 1 month after CO poisoning were evaluated using the Global Deterioration Scale combined with neurological impairment. Results: After PSM, the neurocognitive outcomes at 1-month post-CO exposure were not significantly different between the 2.8 ATA (110 patients) and 3.0 ATA (55 patients) groups (p=1.000). Similarly, there was also no significant difference in outcomes in a subgroup analysis according to poisoning severity in matched patients (165 patients) (mild [non-intubated]: p=0.053; severe [intubated]: p=1.000). Conclusion: Neurocognitive sequelae at 1 month were not significantly different between HBO₂ therapy pressures of 2.8 ATA and 3.0 ATA in patients with acute CO poisoning. In addition, the 1-month neurocognitive sequelae did not differ significantly between intubated and non-intubated patients.

In 1998, there was heavy precipitation of 60 days with amount of 1,042mm from June to September in Andong. Upland crop was severely injured by excessive moisture(EM) on poor drainage field. In this trial, effects of EM on the growth characteristics and yield in Peucedanum japonicum Thunberct and Rehmannia glutinosa Liboschitz was investigated. In Peucedanum japonicum Thunberct, growth of root was decreased more severely than that of aerial part by EM injury, and fresh weight of root per ha was decreased by $21{\sim}80%$ at different degree of EM injury compared to that of normal growth. In Rehmannia glutinosa Liboschitz, percent of withered plant was $10{\sim}52%$ at different degree of EM injury. and rhizome's number per plant and diameter was extremely decreased by EM injury. Fresh weight of rhizomes per ha was decreased by $19{\sim}83%$ at different degree of EM injury compared to that of normal growth.

This study was conducted to assess effects of soil moisture condition and ventilation on development of fermented fruit of oriental melon. In higher soil moisture condition (-10 kPa), roots absorbed more water and transpiration was decreased under low temperature and high humidity conditions. Development of fermented fruit may be come from absorbed water concentrated placenta with higher soluble solid. Fermented fruit was developed with higher level at Shintozoa and Elite, was developed with lower level at Hongtozoa, and was not developed at self-rooting of oriental melon. Ventilation on fruit did not affect development of fermented fruit at Shintozoa, Elite, Hongtozoa and self-rooting seedling. Ca contents of flesh and placenta of fruit under ventilation treatment were higher than control but contents of Acetaldehyde, Ethanol and Ethylacetate were lower.

Uterine leiomyomas (UL) are extremely common neoplasms in women of reproductive age, and are associated with a variety of characteristic choromosomal aberrations (CAs). The p53 gene has been reported to play a crucial role in suppressing the growth of a variety of cancer cells. Therefore, the present study investigated the effects of CAs and the p53 gene on ULs. We performed cytogenetic analysis by G-banding in 10 cases undergoing myomectomy or hysterectomy. Fluorescence in situ hybridization (FISH) with a p53 gene probe was also used on interphase nuclei to screen for deletions. In patients, CAs were found in 23.4% of 500 cells analysed, significantly more frequent than in the control group (p<0.001). In the patients, 76% of the abnormalities were structural aberrations (deletions, translocations and breaks), and only 24% were numerical. Deletions were the most common structural aberration observed in CAs. Among these CAs, specific changes in five loci 1q11, 1q42, 2p23, 5q31 and Xp22 have been found in our patients and these changes were not reported previously in UL. The chromosome breaks were more frequent in cases, from high to low, 1, 2, 6, 9, 3, 5, 10 and 12. Chromosome 22, X, 3, 17 and 18 aneuploidy was observed to be the most frequent among all numerical aberrations. We observed a low frequency of p53 losses (2-11%) in our cases. The increased incidence of autosomal deletions, translocations, chromatid breaks and aneuploidy, could contribute to the progression of the disease along with other chromosomal alterations.

Objectives : The aim of this study was to investigate Korean Wechsler Intelligence profiles and specific abilities related to attention problem of children with attention-deficit hyperactivity disorder (ADHD). Methods : The Korean Wechsler Intelligence Scale for Children-fourth edition (K-WISC-IV) and Advanced Test of Attention (ATA) were administered to 91 children and adolescents (age $8.5{\pm}2.6$ years, 73 boys) with ADHD. Pearson correlation and independent t-tests were used. Results : The means of Working Memory Index (WMI) and Processing Speed Index (PSI) showed a score of low average in K-WISC-IV. WMI scores for the K-WISC-IV showed clinically significant correlations with omission errors, commission errors, and response time variability on auditory ATA. PSI scores also showed significant correlations with response time and variability on visual ATA. In addition, significantly lower digit span backward scores were observed in hyperactive-impulsive/combined subtypes compared to inattentive subtype (t=3.60, p<.001). Conclusion : Children with ADHD showed significantly lower scores in WMI and PSI which were clinically correlated with ATA scores, and hyperactive-impulsive/combined subtypes showed poorer working memory functions in WMI. Follow-up studies are proposed.
