In the results of investigating the role of LED light quality in enhancing the ornamental value of indoor foliage plants, amber and red light increased plant height, leaf width, and leaf stalk, and the consequent tree shape decreased the ornamental value. The chlorophyll content increased significantly under white light and compound light. With regard to the effect of plant leaf color on ornamental value, the value of lightness was markedly enhanced by red light. As to the functionality of plants according to photosynthetic activity, plants such as Dieffenbachia, Clusia, and Dracaena were found favorable to those staying indoors for a longtime from morning to evening. Spathiphyllum, and Ficus were found to be recommendable for indoor spaces used actively during afternoon because their photosynthesis was activated in the afternoon. With regard to power consumption according to light quality, white light consumed 119 W/hour, around 45% lower than that of fluorescent lamps, so it is considered the optimal artificial light quality that can enhance energy efficiency. Red light consumed 72 W/hour, only 33% of that of fluorescent lamps, but it was not considered the optimal light quality because plant growth was poor under the light quality. White light and compound light were found to be the ideal light sources for improving the functionality and ornamental value of indoor plants and reducing the cost of maintenance, but because compound light hinders people from recognizing the original color of plants and makes their eyes easily tired, white light was considered the optimal light satisfying all of the ornamental value, economic efficiency and functionality resulting from plant growth.

White light and compound light were found to be the ideal light sources for improving the functionality and ornamental value of indoor plants and reducing the cost of maintenance, but because compound light hinders people from recognizing the original color of plants and makes their eyes easily tired, white light was considered the optimal light satisfying all of the ornamental value, economic efficiency and functionality resulting from plant growth. On the other hand, in the results of examining physiological changes before and after treatment on fine dust PM10 and carbon dioxide removal capacity in a closed chamber under an artificial light source, the patterns of carbon dioxide and fine dust removal were similar among the treatment groups according to light condition, but according to plant type, the removal rate per unit leaf area was highest in Spathiphyllum and lowest in Dieffenbachia. In the experiment on dust and carbon dioxide removal, the photosynthetic rate was over 2 times higher after the treatment, and the rate increased particularly markedly under compound light and white light, suggesting that the photosynthetic rate of plants increases differently according to light quality. These results show that light quality has a significant effect on the photosynthetic rate of plants, and suggests that plants with a high photosynthetic rate also have a high carbon dioxide and dust removal capacity. In conclusion, the photosynthetic rate of foliage plants increased under white and blue light that affect photosynthesis and the increased photosynthetic rate reduced carbon dioxide and fine dust, and therefore white and compound light were found to be the optimal light sources most functional and economically efficient in improving ornamental value and indoor air quality.

N/A Radioiodine[131I] has been used for the treatment of Graves' hyperthyroidism since the late 1940's and is now generally regarded as the treatment of choice for Graves' hyperthyroidism who does not remit following a course of antithyroid drugs. But for the dose given, several different protocols have been described by different centers, each attempting to reduce the incidence of long-term hypothyroidism while maintaining an acceptable rate control of Graves' hyperthyroidism. Our goals were to evaluate effective half-life and predict absorbed dose in Graves' hyperthyroidism patients, therefore, to calculate and readminister radioiodine activity needed to achieve aimed radiation dose. Our data showed that the mean effective 131I half-life for Graves' disease is 5.3 days(S.D=0.88) and mean biologic half-life is 21 days, range 9.5-67.2 days. The mean admininistered activity and the mean values of absorbed doses wert: 532 MBq(S.D.=254), 112 Gy (S.D.=50.9), respectively. The mean activity needed to achieve aimed radiation dose were 51 MBq and marked differences of 131I thyroidal uptake between tracer and therapy ocurred in our study. We are sure that the dose calculation method that uses 5 days thyroidal 131I uptake measurements after tracer and therapy dose, provides sufficient data about the effective treatment in Graves' hyperthyroidism

N/A Radioactive iodine has been widely used in patients with thyroid cancer combined with surgical treatment. However, due to individual variations in absorption and excretion and uptake by tumor tissue of radioactive iodine, there are differences in therapeutic effect and adverse effects even if the same doses are administrated. So this study compared the therapeutic effect and radiation hazard by measuring internal radiation dose. Of total 27 patients with well differentiated thyroid cancer who had been thyroidectomized, we administered radioactive iodine 100 mCi, 150 mCi, 200 mCi. According to BEL DOSIMETRY PROTOCOL, beta and gamma ray dose were estimated from a polt of the logarithrn of the percent of dose per liter of whole blood versus day, and percent dose retained versus day using semilogarithmic paper, respectivel y. 1) Physical dose to whole blood averaged 56.54+13.02 rad in 100 mCi administered group, 76.83+ 19.97 rad in 150 mCi administered group, 95.08 +- 25.51 rad in 200 mCi administered group and there has been a significant correlation among the groups. 2) Mean percent dose retained 48 hours later was 26.34%. 3) There was no significant correlation of physical dose between absence and presence of metastasis. 4) l7 of 19 patients who has been followed up with TSH and serum throglobulin, Thallium scan were successfully ablated by radioactive iodine. 5) Leukocyte, lymphocyte, neutrophil, platelet counts all declined in 4-6 weeks and most of all were restored 3 months 1ater. 6) There was no significant correlation between physical dosimetry and biologic dosimetry. Generally administered doses of radioactive iodine (100-200 mCi) to patients with thyroid cancer postoperatively had developed transient bone marrow suppression and minimal chromosomal aberration, but they were within safety dose to blood (200 rad). And there has been no significant differences in residual dose 48 hours later between Korean and western people.

Objectives This study investigated associations between symptom severity and neurocognitive functions in patients with major depressive disorder using comprehensive neuropsychological tests. Methods Ten patients with low depression (LD) and 22 patients with high depression (HD) participated. Symptom severity was determined by both the Beck Depression Inventory and the Hamilton Depression Rating Scale. Additionally, anxiety was measured by the Korean version of the State-Trait Anxiety Inventory (STAI-KYZ). Ten subtests of the Korean-Wechsler Adult Intelligence scale (K-WAIS), Stroop test, the word/design fluency tests were administered to assess cognition. Results The LD and HD groups did not differ in any of cognitive measures but anxiety level. Namely, the HD group obtained significantly higher scores on the state (U = 29.50, p < 0.01) and trait (U = 28.50, p < 0.001) anxiety scales than the LD group. A significant interaction effect between trait anxiety and depression severity was observed on the picture arrangement subtest of the K-WAIS [F (1, 27) = 5.09, p < 0.05]. Conclusions Cognitive deficits observed in patients with major depressive disorder may be related to other factors rather than current symptom severity. Trait anxiety possibly moderates the effect of current symptom severity on social judgment in these patients.

소변은 쉽게 채취할 수 있으며 체내의 상태를 파악하기에 좋은 시료라고 할 수 있다. 본 연구에서는 2주간의 한식 섭취 후 변화된 소변 유기산 지표를 찾을 수 있었다. 그 결과 에너지 대사와 관련 있는 대사산물인 succinate, hydroxymethylglutarates 뿐만 아니라 tryptophan 대사물로써 신경전달 물질대사 지표인 5-hydroxyindoleacetate, 비타민 B6, 염증, 면역과도 관련이 있는 kynurenate, 장내세균과 관련 있는 indican이 한식의 섭취를 통해 유의한 차이로 변화하는 것을 확인하여 한식의 효능이 어떤 대사를 통하여 이루어 지는지의 방향 제시를 하였다. 또한 소변 유기산이 한식의 대사에 미치는 영향을 측정하는 생체지표로서의 활용 가능성도 보여주었다. 객관적인 지표로서 확증하기 위해 더욱 큰 표본에서의 연구, 성별, 질병별 다양화한 연구를 통해 관찰된 지표들의 재현성을 확인하여 생체 지표로서의 유효성 검증이 필요하겠다. Purpose: To determine the metabolic influence of the traditional Korean diet (K-diet), which has been regarded as a healthy diet, we investigated the profile of urine organic acids that are intermediates of various types of metabolism including energy metabolism. Methods: Ten women aged 50–60 years were recruited and randomly divided into 2 diet groups, K-diet and control diet, the latter of which is a Westernized Korean diet that is commonly consumed by Koreans nowadays. Before and after the 2-week intervention, 46 urine organic acids were determined using LC/MS/MS, along with clinical parameters. Results: The average concentrations of succinate (4.14 ± 0.84 μg/mg creatinine vs. 1.49 ± 0.11, p = 0.0346) and hydroxymethylglutarate (3.67 ± 0.36 μg/mg creatinine vs. 2.97 ± 0.29, p = 0.0466), both of which are intermediates of energy metabolism, decreased in the K-diet group after the 2-week intervention, but these were not observed in the control diet group. In particular, the average concentration of succinate in the K-diet group was lower than that in the control group (3.33 ± 0.56 μg/mg creatinine vs. 1.49 ± 0.11, p = 0.0284) after 2 weeks. The concentrations of two tryptophan metabolites, 5-hydroxyindolacetate (3.72 ± 0.22 μg/mg creatinine vs. 3.14 ± 0.21, p = 0.0183) and indican (76.99 ± 8.35 μg/mg creatinine vs. 37.89 ± 10.06, p = 0.0205) also decreased only in the K-diet group. After the 2-week intervention, the concentration of kynurenate, another tryptophan metabolite, was lower in the K-diet group than that in the control diet group (3.96 ± 0.51 μg/mg creatinine vs. 2.90 ± 0.22, p = 0.0356). Interestingly, the urine level of kynurenate was positively correlated with BMI (r = 0.61424, p = 0.0003) and total cholesterol (r = 0.46979, p = 0.0088), which decreased only in the K-diet group (239.40 ± 15.14 mg/dL vs. 198.20 ± 13.25, p = 0.0163). Conclusion: The K-diet alters the urinary excretion of organic acids involved in energy metabolism and tryptophan metabolism, suggesting the influence of the K-diet on these types of metabolism. Urine organic acids changed by the K-diet may serve as biomarkers in future studies.

Purpose: Assessment of the diameters of the aortic arches in the human fetus may be helpful in the prenatal diagnosis of aortic arch anomalies. The purpose of this study is to construct valuable reference ranges of fetal aortic arch for various fetal growth parameters in an unselected Korean population. Method: A prospective, cross-sectional study was performed in 98 normal singleton fetuses between 20 and 38 weeks of gestation. The transverse aortic arch diameter (TAD) and distal aorta isthmus diameter (AID) were measured in the longitudinal view during systole. The bi-parietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL) were obtained at the same time. Ultrasound examinations were performed with a 2.0-6.0 MHz convex probe by abdominal ultrasound. Results: TAD and AID as a function of gestational age (GA) was expressed by the regression equation TAD= -1.246+0.168 X GA, and AID=-1.341+0.180 X GA; TAD and AID are expressed in millimeters and GA in weeks. TAD and AID as a function of BPD was expressed by the regression equation TAD= -1.147+0.664 X BPD, and AID=-1.152+0.696 X BPD. TAD and AID as a function of HC was expressed by the regression equation TAD=-1.187+0.182 X HC, and AID=-1.350+0.198 X HC. TAD and AID as a function of AC was expressed by the regression equation TAD=-0.528+0.173 X AC, and AID=-0.533+0.183 X AC. TAD and AID as a function of FL was expressed by the regression equation TAD=-0.519+0.799 X FL, and AID=-0.601+0.860 X FL; BPD, HC, AC and FL are expressed in centimeters. Correlations were found to be highly statistically significant in relation to GA, BPD, HC, AC, and FL respectively ( P<0.0001 in all). Normal mean of TAD and AID per GA, BPD, HC, AC and FL and 95% prediction limits were also defined, respectively. Conclusion: New reference ranges of fetal aortic arch related to other fetal bio-parameters representing fetal growth were obtained successfully. The normative date will be helpful in the prenatal accurate diagnosis of aortic anomalies and abnormal growth of fetal aortic arches in Korea.

This study was performed to identify the effect of mixed bed soil on growth of aerial parts and root zone of daughter plants for nursery field strawberry seedling raising with expanded chaff. The plant height and leaf area of daughter plants were highest or largest in the mixed soil of ERH +RH (100:0, v/v), followed by ERH+RH (75:25). The higher the mixing ratio of RH, the shorter the plant height or the smaller the leaf area. A similar tendency was observed in fresh weight. Within a root diameter of 0-0.4 mm and a root height range of 0.4-0.8 mm, root surface area and volume were statistically significantly better with treatment of ERH+RH (100:0, v/v) compared to those of roots treated with ERH+RH (75:25), ERH+RH (50:50) and ERH+RH (25:75). The growth rate of aerial parts and root zone of daughter plants were noticeably lower in two mixing ratios of 50:50 and 25:75. According to the mixing ratios of ERH+CD surface treatment, the number of roots was greatest in plants treated with ERH+CD (80:20, v/v) and ERH+CD (85:15) on August 1. However, the number of roots was highest in plants treated with ERH+CD (85:15, v/v) on August 15. Root length was longest in the plant with no treatment, and drastically shortened from ERH+CD (90:10, v/v) in both surface and mixed treatment. Although root weight showed a significant difference in ERH+CD (90:10, v/v) treatment, its increase was gradual. The rate of root growth was highest in ERH+CD (85:15). These study findings suggest that the content ratios of mixed soil ERH+RH (75:25, v/v) or below and ERH+CD (85:15) are thought to be desirable for the production of high quality seedlings.

조생종 ‘원황’의 과육 및 과심갈변 장해와 저장온도 및 에틸렌제어의 효과를 검토하기 위하여 본 연구에서는 2년에 걸쳐 유사한 시기에 ‘원황’과 실을 수확하여 저장온도에 따른 생리장해와 1-MCP 처리의 효과를 조사하였다. 저장온도에 따른 장해의 발생은 해에 따라 일정하지 않았으며 비슷한 시기에 수확한 과실이지라도 가용성 고형물함량이 높고 경도가 낮았던 해의 과실에서 저장온도(0-10℃)에 관계없이 장해 발생이 심하였다. 1-MCP 처리는 갈변 발생에 미치는 영향이 명확하지 않았다. 따라서 ‘원황’의 갈변장해는 수확기의 과실의 성숙 상태의 영향을 받으므로 앞으로의 연구에서 ‘원황’의 적정 수확시기에 대한 보다 구체적인 연구가 필요할 것으로 판단된다. ‘Wongwhang’ pear often suffered from the incidence of core and/or flesh browning, which is known to be associated with an improper postharvest handling including storage temperature. We examined the effect of storage temperatures and 1-MCP treatment on the occurrence of browning disorder in ‘Wonwhang’ pears (Pyrus pyrifolia Nakai). The incidence of flesh and/or core browning was not consistent to storage temperature (0-10℃). Fruit with high soluble solids and low firmness (more mature fruit) at harvest showed a tendency of high incidence of browning disorder regardless of storage temperature and the effect of 1-MCP (0.5 to 1 ㎕.L<SUP>-1</SUP>) on disorder occurrence was not clear. The browning disorder in ‘Wonwhang’ appeared to be rather affected by the maturity of fruit at harvest. Future study including determination of accurate maturity indices for harvest is required to prevent the postharvest suffering by browning disorder.
