Acute betaine treatment induces time-dependent changes in the hepatic glutathione (GSH), cysteine and S-adenosylmethionine (SAM) levels. Our previous study demonstrated that betaine administered $1{\sim}4$ hours prior to sacrifice decreased hepatic GSH levels, but these levels were increased when measured 24 hours following the treatment. The present study was aimed to determine dose-dependent effects of betaine on hepatic metabolism of sulfur amino acid in mice. Mice were sacrificed 2.5 or 24 hours after intraperitoneal treatment with betaine at different dose levels ranging from 50 to 1000 mg/kg. The concentrations of methionine and SAM were increased by a betaine dose of 100 mg/kg, and the concentrations of GSH and cysteine were decreased by a betaine dose of 200 mg/kg at 2.5 hours. These changes were augmented with increasing doses of betaine. At 24 hours following betaine treatment, increased GSH and decreased taurine levels were observed from dose levels of 400 mg/kg. Changes in hepatic activities of cystathionine beta-synthase, gammaglutamylcysteine ligase and cysteine dioxygenase were observed from dose levels of $200{\sim}400$ mg/kg of betaine administered 24 hours prior to sacrifice.

1) Germination rate was rather irregular than decreasing as increasing dose of radiation and there were no differences between Kyong-Sam and Chuong-Bang of Chinese cabbage. 2) In R1 generation, abnormal leaves from seedling of irradiated seeds were observed. These were more apparent in X-ray irradiation than in thermal neutron. 3) Seedling height was inhibited with increasing dose of X-ray and thermal neutrons. Growth inhibition was more remarkable in X-ray than in thermal neutron. Kyong-Sam demonstrated more sensitivity than Chyong-Bang in both X-ray and thermal neutron. 4) Seedling height produced from seeds subjected to thermal neutrons showed small variation around its mean value, while in X-irradiation there was a greater deviaton from the mean value. 5) Fertility was decreased as increasing with dose, while the frequency of abortive pollen was increased. There were variability of the fertility and frequency of abortive pollen among plants or branches of a plant. 6) The mutants were obtained more in thermal neutron irradiation than in X-ray. The types of mutations obtained in Chinese radish of R2 generation were abnormal leaf, densely glowing leaf, degeneration in growing point and dwarf. The maximum frequency of phenotypic mutations was abnormal leaf mutation.

As mentioned above, I have acquired some valuable results about medical treatments with acupuncture for "Trigeminal neuralgia" after studying oriental medical books. 1. The course of medical treatments with acupuncture was, first of all, applying general ones, and then, assisting ones based on occuring area of pain and the cause. 2. For general treatments, "Chok-yangmyong-Wi-Kyong", distributed widely on the face, was used in great numbers. The order, according to the number of using times, of spots for acupuncture was Ha-kwan(11 times), Hap-kok(10), Chan-juk(7), Hyop-geo, Tae-yang, Sa-baek(individually 6). 3. For assisting treaments based on occuring area of the pain, spots of the Kyong-rak, passing through occuring area of the pain, and Kyong-woe-ki-hyol were used in great numbers. 4. The order was O-je, Chan-juk, Yang-baek(individually 8), Tae-yang(5) for the pain of first branch of the trigeminal nerve; Sa-baek(12), Kwan-ryo(6), Go-ryo(5) for the pain of second one; and Hyop-geo, Ha-kwan(individually 6), Dae-young, Hyop-seung-jang(individually 5). Seung-jang(4). 5. For assisting treatments based on the cause, "One-hyol(原穴)", "Rak-hyol(絡穴)" and "5-soohyol(五輸穴)" were used in great numbers. 6. The order was Pung-ji(10), Hap-kok(9), Woe-kwan(5) for "Woe-Kam(外感)"; Nae-jong(12), Tae-chung(10), Chok-sam-ri(7) for "Kan-Wi-Hwa-Seung(肝胃火升)"; Tae-gue(7), Sam-um-kyo, Pung-ji(individually 2) for "Ho-Hwa-Sang-Seung(虛火上升)"; Pung-ryung(4) for "Pung Dam-Jo-R ak (風痰阻絡)"; Kyok-su(2) for "Ki-Che-Hyol-Ho(氣滯血虛)".

The purpose of this study was to investigate the salt and sodium content of lunch meals served at middle schools in Gyeongsangbuk-do. Four middle schools were investigated for their salt and sodium content and salt content contributing rate per meal. Average salt content of every lunch meal was 4.41 g, and average sodium content was 1,736.02 mg. During the investigation period, the lowest sodium content was 943.19 mg while the highest was 2,827.56 mg. Samples were classified into 16 food items and investigated for salt and sodium content. Total average salinity was 1.06%. Kimchi was the saltiest, followed by fresh-vegetables, boiled-vegetables, stir-fried foods, pan-fried foods, and hard-boiled foods. Total average salt content was 0.74 g, and most salty dishes were single dish rice noodles, followed by stews, steamed foods, broths, soups, kimchies, stir-fried foods, roasted foods, and hard-boiled foods. Samples were classified into seven menu groups, including cooked rice, single dish rice noodles, soup stew, main dish, side dish, kimchi, and desserts. Contributing rate of total average salt content was high in single dish rice noodles (40.56%), soup stew (23.23%), kimchies (20.30%), and main dish (18.13%). These results can be useful for establishing a database for sodium contents of meals in middle schools. 'SamSam foodservice' should be initiated in school foodservice to reduce sodium intake.

To investigate soil management practices for increasing tree growth in arid regions of China, Xinjiang poplar (Populus alba var. pyramidalis) seedlings were planted in a nursery and windbreak and were treated with fertilizers (nitrogen and phosphorus) and absorbents (artificial; K-SAM and natural: Yuho (Artemisia ordosica)) at Dengkou in Inner Mongolia. Seedling height, diameter at breast height (DBH), biomass, and nitrogen (N) and phosphorus (P) concentrations were measured 1.5 years after the treatments. Soil texture was sandy loam for nursery and clay loam for windbreak, soil pH was 8.78 for nursery and 8.51 for windbreak, and total soil N concentration was 0.06% for nursey and 0.08% for windbreak. [n general, seedling height and DBH increased in the N fertilizer treatment compared to control or other treatments both in nursery and windbreak. Also seedling growth increased after the treatments of artificial and natural absorbents in windbreak. Total above- and belowground biomass increased after the N + P treatment. Foliage N and P concentrations following N and/or P treatments were same in the nursey, however, they significantly increased in the windbreak indicating N deficiency. It appeared that N was a limiting factor for early growth of Xinjiang poplar seedlings and artificial and natural absorbents (K-SAM and Yuho) would be useful to increase seedling growth in the arid region.

This study was performed to investigate the effect of kimchi intake on antiaging characteristics in liver of senescence-accelerated mouse (SAM) in terms of free radical production and anti-oxidative enzyme activities. Two hundred twenty SAM were divided into four groups and fed kimchi diet for 12 months. Experimental groups were kimchi free AIN-76 diet (control) group, Korean cabbage kimchi diet (KCK) group, mustard leaf added (30%) Korean cabbage kimchi diet (MKCK) group, and mustard leaf kimchi diet (MLK) group. Amount of freez-dried kimchi added to the diet was 5% that is equivalent to 50 g of fresh kimchi. Concentrations of total free radical, OH radical, $H_2O$$_2$in the liver significantly increased as aged (p<0.05). But those free radical concentrations from kimchi diet groups were lower than those of control (p<0.05). Among kimchi groups, MKCK and MLK groues showed greater inhibiting effect than KCK. Antioxidant enzyme activities of Cu, Zn-SOD, Mn-SOD, GSH-px, catalase and GSH/GSSG in kimchi groups were significantly increased (P

In the shipyard, aerial images are acquired at regular intervals using Unmanned Aerial Vehicles (UAVs) for the management of external storage yards. These images are then investigated by humans to manage the status of the storage yards. This method requires a significant amount of time and manpower especially for large areas. In this paper, we propose an automated management technology based on a semantic segmentation foundation model to address these challenges and accurately assess the status of external storage yards. In addition, as there is insufficient publicly available dataset for external storage yards, we collected a small-scale dataset for external storage yards objects and equipment. Using this dataset, we fine-tune an object detector and extract initial object candidates. They are utilized as prompts for the Segment Anything Model(SAM) to obtain precise semantic segmentation results. Furthermore, to facilitate continuous storage yards dataset collection, we propose a training data generation pipeline using SAM. Our proposed method has achieved 4.00%p higher performance compared to those of previous semantic segmentation methods on average. Specifically, our method has achieved 5.08% higher performance than that of SegFormer.
