Anatomical and physiological studies of sink tissues are required for better understanding the biological plant growth system and energy metabolism Anatomy of root growth zones of two genotypes of tall fescue (Festuca arundinacea Schreb.) receiving 50 or 200 ppm N were determined, Cross-sectional anatomy and cells responses of root growth zones were observed and examined. Rapid radial root expansion occurred within the first 1.0 mm from root apex, and then increased gradually for both genotypes and N levels. Another increase in diameter occurred at high N after cell elongation slowed near 3.0 mm. Area of the central cylinder cell increased rapidly near the root apex. However, it then decreased again about 1.0 to 1.5 mm from the apex, perhaps because of pressure from the rapid increase of root diameter due largely to an increasing proportion of cortex and epidermis or hypodermis in the distal portion of the root growth zone. Root area from the apical initial to 6.0 mm distal consisted of 10 to 18% epidermis or exodermis, 67 to 79% cortex, and 10 to 22% vascular cylinder cells containing cambium cells (6 to 20%) and xylem cells (0.8 to 2.5%). These data indicate that N application affects root growth radially by increasing mainly cortex cell area, with less effect on epidermis and central cylinder cells.

Kidney stones are largely classified into kidney stones, ureter stones, and urolithiasis depending on the location of their occurrence. Therefore, in this study, from January 2019 to June 2021, kidney stones found in 112 patients with flank pain or who visited for abdominal ultrasonography at a general hospital located in Daegu were diagnosed with urolithiasis. We wanted to investigate the effect on twinkling artifacts. As a result of the study, the incidence of twinkling artifacts due to kidney stones was relatively high in the longitudinal scan among the scan methods. As the number of kidney stones increased, the incidence of twinkling artifacts increased by 1.296 times (p<0.05). As the kidney stone size increased, the incidence of twinkling artifacts increased by 0.086-fold (p<0.05). It was found that the number and size of kidney stones are factors affecting twinkling artifacts. Since the effect of kidney stones on twinkling artifacts is related to the number and size of kidney stones, continuous attention should be paid to helping the detection of kidney stones by using variables affecting twinkling artifacts.

The extent of renal biopsy indication is being widened because of the increasing incidence of incidental renal masses; the increasing treatment options for renal cell carcinoma, including ablation therapy and novel targeted treatment; and the increasing incidence of kidney transplantation. However, percutaneous renal biopsy is technically difficult, particularly for beginners, because the skin-to-organ distance is relatively longer than those associated with other organs. In the present review, we will discuss the indications, technical considerations, efficacy, and complications of renal biopsy. Furthermore, we share practical tips of renal biopsy through many examples to help radiologists perform renal biopsy safely and effectively in various situations.

Factors influencing elongation of the ovipositor in the bitterling Rhodeus uyekii were examined under several conditions. The ovipositors of the females were periodically elongated under the presence of mussels or males, and in some cases without either. When females were reared without mussels and males, the ovipositor did not elongate in one fish in a large aquarium, but it did become elongated in another fish in a small aquarium and in many fishes in a large aquarium. Duration of the elongated state of the ovipositor was 1~3 days (mean 1.2~2.5 days) and the periodicity of elongation was 4~15 days (mean 6.4~11.9 days). Length of the elongated ovipositor was 68~100% (mean 78.5~98.8%). Length of ovipositor in the interpeak period was 20~51% (mean 27.3~33.1%); in the post-elongation period it did not elongated further 3~30% (mean 11.1~19.9%). The effect of aquarium size and number of individuals in the aquarium on the elongation of the ovipositor, and inter-specific or inter-generic differences based on previous reports are discussed.

Changes of protein contents and amino acid composition and SDS-PAGE pattern of protein of mung bean which were germinated in dark at $25^{\circ}C$ for 6 day. The total protein contents gradually decreased during germination and the contents of each fractionative soluble proteins were increased shortly after the soaking of mung bean and gradually decreased during the germination afterwards. SDS-PAGE of albumin fraction showed 18 bands, and during the germination the most of bands were diminished or disappeared. But protein bands at 24,000, 40,000, 45,000, 70,000 dalton position remained until 6th day of germination. SDS-PAGE of globulin fraction showed 6 discrete bands, and during the germination the protein band at 45,000 dalton position disappeard. But the protein bands at $14,000{\sim}25,000$ dalton position did not change during the period. SDS-PAGE of glutelin fraction showed 10 discrete bands, and during the germination the bands of $45,000{\sim}70,000$ dalton become diminished or disappeared. But the bands of 30,000, 60,000 dalton did not change throughout the germination period.

This study is aimed to establish the direction of orthodontic treatment by analyzing the differences in the dental arch development due to the cause of short stature. Dental diagnostic tests were conducted on patients who were diagnosed with short stature. Idiopathic short statured children were classified through the paired sampling based on the age and gender of a short statured children with growth hormone shortage. Control groups were classified using same method as above, after selecting candidates with an arch length of less than 3mm and malocclusion. In conclusion, short statured children with growth hormone shortage or idiopathic had the higher rate of crowding and the small value of overbite compared to normal children. Therefore orthodontic treatment for short statured children needs treatment plan included evaluation for Arch length discrepancy to treat a crowding early. This study will provide important data for successful orthodontic treatment according to the characteristics of dental occlusion of short statured children.

『옥추보경』(玉樞寶經)은 송대의 유명한 도교 경전으로 정식 명칭은 『구천응원뇌성보화천존설옥추보경』(九天應元雷聲普化天尊說玉樞寶經)이다. 송·원시대 이후 『옥추보경』은 중국 각 지역에 광범위하게 전해지면서 많은 영향을 끼쳤으며, 명나라의 세종(世宗)과 신종(神宗)은 『옥추보경』을 새로 간행하여 직접 서문을 쓰고 동시에 매우 숭앙하였다. 『옥추보경』의 집주본이 조선에 전해진 시기는 대략 명대 시기로 보고 있으며, 조선시대에 전해졌던 『옥추보경』 집주본은 융경(隆慶) 4년(1570)에 전라도 무등산(無等山) 안심사(安心寺)에서 최초로 발간되었다. 그러나 당시 안심사 판본은 첫 페이지와 경문 중의 또 다른 페이지가 없는 불완전한 판본이었다. 옹정(擁正) 11년(1733)에 송몽삼(宋夢三), 서두추(徐斗樞) 등의 제안에 따라 영변(寧邊) 묘향산(妙香山) 보현사(普賢寺)에서 『옥추보경』을 새로 간행하게 되었다. 하지만 이 또한 불완전한 판본이었으며, 병진년(1736)에 잃어버린 두 페이지를 우연히 찾게 되면서 완전한 판본을 이루게 되었다. 이후 광서(光緖) 무자년(1888)에 김흡(金潝)이 『옥추보경』을 새로 교정하였고, 계룡산(鷄龍山)에서 이를 다시 간행하였다. 명대의 『도장』에 수록된 『옥추보경』 집주본에는 신장도(神將圖)가 포함되어 있지 않았다. 하지만 조선시대 세 종류의 판본은 모두 신장도(神將圖)가 포함되어 있다. 이 외에도 조선시대 간행본과 비슷한 판본으로 영국의 대영도서관 소장본과 일본 천리대학(天理大學) 도서관의 소장본 및 중국 국가 도서관 고적관의 소장본이 있다. 그런데 안심사 판본은 41명, 보현사 판본은 47명, 계룡산 판본은 48명의 신장도가 포함되어 있으며, 대영도서관은 45명, 중국 국가 도서관은 45명 등으로 차이가 있다. 이러한 판본들에 수록된 신상의 수가 다른 이유는 아직 명확하지 않다. 이에 본문에서 필자는 먼저 계룡산 판본 『옥추보경』에 근거하여 48신장의 내력에 대한 초보적인 고찰을 진행하였다. 언어상의 문제로 『옥추보경』과 관련된 한국의 연구 성과를 반영하지는 못했지만, 『옥추보경』의 48장과 대순진리회의 『전경』에 등장하는 48장이 어떠한 연관이 있는지를 조명하는 데 유의미한 기초 작업이 될 것으로 전망한다. 이를 토대로 나아가 대순진리회의 48신상도와 『옥추보경』의 판본간의 형태적 특징에 주목하여 면밀한 상호 분석을 시도함으로써 대순진리회의 신앙체계와 『옥추보경』의 관련성을 규명하는 데 일조할 수 있기를 기대한다.

The present experiments were conducted to investigate the variability of hypocotyl elongation among the major soybean varieties by checking several conditions. The results obtained are summarized as follows. The rate of hypocotyl elongation is the highest during the day from 3.0 to 3.5 after seeding. It follows that it may be reasonable to evaluate the hypocotyl elongation of soybean seeds by comparison of hypocotyl length. And the tested 15 major cultivars could be classified as follow ; long ; Eunhakong, Janggyungkong and Bokwangkong, medium ; Namhekong, Dangyung-kong, Danyubkong, Milyangkong, Dugyukong, Paldalkong, Mangunjoseng, Namchunkong and Seal kong, short ; Gwanggyo, Begunkong and Jangbegkong. The hypocotyl elongation in small seed is longer than large seed. Correlation coefficients(r) for the relationships between 100 seed weight and hypocotyl elongation is -0.2506$^{**}$. As the rising temperature, the hypocotyl length is elongated, and longest at the range of 30 to 35$^{\circ}C$. The effects G $A_3$ hastened the hypocotyl elongation of soybean seed, and ABA, Kinetin and BA inhibit it, and that of those in short hypocotyl cultivars are higher than long hypocotyl cultivars. Hypocotyl length of long hypocotyl cultivars are longer than that of short hypocotyl cultivars under high temperature pre -treatment.

The aims of this study were to evaluate the difference of renal uptake rate in $^{99m}Tc-DMSA$ scan on pediatrics by including the bladder. Phantom and Clinical studies were performed. In the phantom study, we put $^{99m}TcO_4{^-}$ (300uCi, 11 MBq) in 3cups filled with distilled water at the rate 1:1:0, 1:1:0.5, 1:1:1, 1:1:2 and were placed Lt kidney, Rt kidney and bladder position on the table. To acquire the image, we used Symbia-E gamma camera from Siemens with preset count method(400,000 counts). In quantitative analysis, the counts of drawing ROIs on the phantom were analyzed. In clinical studies, we analyzed the 20 pediatrics who were examined by $^{99m}Tc-DMSA$ scan. At first, the images were acquired with both kidney and bladder. Secondly we acquired images after shielding the bladder. And the data were compared using a pared t-test by SPSS(ver.22.0). As a result of renal phantom's experiment, we compared with average of uptake rate(%), 1:1:0 was Lt 43.32%, Rt 45.97%, 1:1:0.5 was Lt 35.79%, Rt 36.89%, 1:1:1 was Lt 29.68%, Rt 31.45% and 1:1:2 was Lt 22.89%, Rt 24.32%. There was no correlation between the zoom and uptake rate. The results of patient were that excluded bladder was $29.83{\pm}8.81%$(Lt), $24.29{\pm}6.66%$(Rt) and included bladder was $26.65{\pm}8.03%$(Lt, $21.78{\pm}6.24%$(Rt). This is deemed statistically significant (p<0.05). Renal uptake rate was undervalued because the counts of bladder were included in the total counts.
