  • An ultraviolet (UV) sterilization system was developed to decrease the number of microorganisms in filtered Acer mono sap (FAS). The Acer mono sap (AS) was passed through 18 strips of PTA fluoroplastic tubing with 30 UV lamps (total 1,170 W). During passage, the AS was effectively exposed to the UV rays. The total bacteria, coliform group and fungi were sterilized at a flow rate ranging from 852 to 1,358 mL/min and a UV power higher than 156 W. Although the sensory score of the UV-sterilized AS was significantly lower than that of the untreated AS, the sensory score was better under the condition of 390 W and 852~1,358 mL/min than under the other conditions examined. ANOVA did not reveal a significant difference in pH, total acidity, sugar content and color characteristic under all conditions tested (p<0.05). Considering the overall attributes of the AS quality, the optimum sterilization condition was determined to be 390 W and 852~1,358 mL/min.

  • Aberrant expression of genes in de novo lipogenesis (DNL) pathway were associated with various cancers, including hepatocellular carcinoma (HCC). Single nucleotide polymorphisms (SNPs) of DNL genes have been reported to be associated with prognosis of some malignancies. However, the effects of SNPs in DNL genes on overall survival of HCC patients receiving transarterial chemoembolization (TACE) treatment are still unknown. In present study, nine SNPs in three genes (ACLY, ACACA and FASN) in DNL pathway were genotyped using the Sequenom iPLEX genotyping system in a hospital-based cohort with 419 HCC patients treated with TACE, and their associations with HCC overall survival were evaluated by Cox proportional hazard regression analysis under three genetic models (additive, dominant and recessive). Although we did not find any significant results in total analysis (all p>0.05), our stratified data showed that SNP rs9912300 in ACLY gene was significantly associated with overall survival of HCC patients with lower AFP level and SNP rs11871275 in ACACA gene was significantly associated with overall survival of HCC patients with higher AFP level. We further identified the significant interactions between AFP level and SNP rs9912300 or rs11871275 in the joint analysis. Conclusively, our data suggest that genetic variations in genes of DNL pathway may be a potential biomarker for predicting clinical outcome of HCC patients treated with TACE.

  • First, during Jin and Sui dynasty, It is possible that the theory of the contraindications of needling according to whereabouts of the self-guarding energy and demon, affected considerably to the practise of acupuncture and moxibustion, but the detailed situations are unknown. Only, there are some records of the process about circulation of the self-guarding energy and demon by a periodicity of 30 days in the "The prescriptions of Fan-Wang" by Fan-Wang in Jin dynasty and "Hua Tuo Fa" by a nameless person. But the theory differs form the theory of "Huang Di Xia Mo Jing" in some respect. Also, there is the contraindications of needling to abscesses according to whereabouts of the self-guarding energy and demon by every year in the "Liu Juan Zi Gui Yi Fang". but the book has no specific rule in use. Second, during Tang dynasty there were a vasty development on the contraindications of needling according to whereabouts of the self-guarding energy and demon. In the medical works in Tang dynasty, the contents of the contraindications of needling are included in various periodicities and directions such as 12 regions according to the year, 9 regions according to the year, 9 palaces in the body according to the year, whereabouts of the self-guarding energy and demon according the four seasons, every 10 days, every 12 days, every 30 days, and every dozen hours. Also, during Tang dynasty period, the contraindications of needling according to whereabouts of the self-guarding energy and demon were formulated through several adjustments and modifications by many medical scholars. Third, the period between Jin and Tang dynasty, because of historical situations, the documentary data are insufficient in the study of the recommendations and contraindications on the acupuncture, moxibution, and herb medicine according to the specific days and times. And the detailed informations are unknown. Only but once in Tang dynasty the considerable and theoretical adjustments were performed in the "Qian Jin Yao Fang". In Song dynasty, there were also much theoretical fluctuations in the study of the choice of the favorable or the injurious days and times or directions in the acupuncture, moxibustion and the prescription and processing of herbs. Fourth, contraindications on the acupuncture, moxibution, and herb medicine did not include acute and serious disease among the effect province, only include chronic and not serious disease. If the doctors had treated a surgical patients and abscess patients with deeply attached contraindications on the acupuncture, moxibution, and herb medicine, the patients would have became more serious. So the theory was not used for treatment by doctor.

  • GGBFS(Ground Granulated Blast Furnace Slag) has been widely used in concrete for its excellent resistance chloride and chemical attack, however cracks due to hydration heat and dry shrinkage are reported. In many International Standards, GGBFS with low fineness of 3,000 grade is classified for wide commercialization and crack control. In this paper, the mechanical and durability performance of concrete were investigated through two mix proportions; One (BS) has 50% of w/b(water to binder) ratio and 60% replacement ratio with low-fineness GGBFS, and the other (TS) has 50% of w/b and 60% replacement ratio with 4000 grade and FA (Fly Ash). The strength difference between TS and BS concrete was not great from 3 day to 91 day of age, and BS showed excellent performance for chloride diffusion and carbonation resistance. Two mixtures also indicate a high durability index (more than 90.0) for freezing-thawing since they contain sufficient air content. Through improvement of strength in low fineness GGBFS concrete at early age, mass concrete with low hydration heat and high durability can be manufactured.

  • The article, focusing on the theory of Zhong-He, sheds a new light on the philosophy of Daizhen. The theory of Zhong-He, according to the philosophical system of Zhuxi, serves as the theoretical foundation in erecting the apriori moral nature and guiding mental cultivation of subjects. Daizhen, on the contrary, criticizes the doctrine of Zhonghe in Zhuxi's philosophy as it produces negative side-effects of moral dogmatism. Zhuxi's doctrine, according to Daizhen, as it reduce the origin of morality to apriori condition of consciousness and delimit the range of cultivation to psychological realm of subjects, restricts moral subjects in the fortress of their own subjectivity. In this vein of his criticism, Daizhen attempts new interpretation on Zhonghe. The character Zhong (中), according to him, does not refer to apriori moral state or metaphysical moral substance as it does in the doctrine of Zhuxi. On the contrary, it denotes the state in which diverse existent beings are placed in their own position by their own dispositions. Similarly, the other character He (和) does not refer to the condition where an individual's consciousness is in equilibrium, but to the process of achieving the harmony of entire society in which diverse existent beings are communicating to each other. With his novel interpretation of the theory of Zhong-He, Daizhen could dissolve the tradition of Weifa (未發) and moral subjectivism in Zhuxi's philosophy and provide a way of establishing reciprocal communication and harmony between various individuals. It is in his ethics of rational mutual understanding where the significance of Daizhen's philosophy should be found.

  • Background: The Unani system of medicine has been practised since centuries for the treatment of a range of diseases. In spite of their efficacy they have been widely criticised due to the lack of standardization and poor quality control. Standardization of Unani medicine is a valuable issue at the present because they are very prone to contamination, deterioration, adulteration and variation in composition due to biodiversity as well as careless collection. Objective: To Standardize and Development of HPTLC Fingerprinting of a polyherbal Unani formulation Qurs-e-Safa. Materials and methods: The conventional and modern analytical techniques were used to standardise Qurs-e-Safa. The study was carried into three different batches of Qurs-e-Safa prepared with its ingredients. The parameters studied are organoleptic, microscopic, physicochemical parameters, phytochemical screening, TLC, HPTLC profile, aflatoxin, microbial load and heavy metal analysis. Results and conclusion: Qurṣ-e-Sa'fa is dark yellow in colour and aromatic smell. Uniformity of diameter and weight variation were found to be 13 ± 0, and 524.7 ± 1.72 mg. friability, hardness and disintegration time of all 3 batches were found to be (0.0615 ± 0.004, 0.0885 ± 0.0047 and 0.0725 ± 0.0058), (3.5 ± 0.2886, 3.67 ± 0.1674 and 3.67 ± 0.1674) and (16 to 17 minutes). Extractive value were found to be maximum in distilled water (38.488 ± 0.20, 37.3824 ± 0.38 and 39.8177 ± 0.13) followed by alcohol (27.5406 ± 0.54, 27.5656 ± 0.32 and 26.9229 ± 0.25). Loss of weight on drying, pH, total ash, acid insoluble ash, qualitative test was set in. Phytochemical screening revealed the presence of Carbohydrates, Phenols, Resins, Proteins, Steroids, fixed oil and Flavonoids. The microbial load was found absent and heavy metals were within permissible limits. The data evolved from the study may serve as a reference to validate and also help in the quality control of other finished products in future research.

  • To discover new functional materials using edible plants, antioxidant activities of methanol extracts from various parts of seven wild vegetables were investigated in vitro. Total polyphenol contents, determined by Folin-Denis method, varied from 16.74 to $130.22{\mu}g/mg$. Radical-scavenging activities of methanol extracts were examined using ${\alpha},\;{\alpha}-diphenyl-{\beta}-pirrylhydrazyl$ (DPPH) radicals and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) assay. Inhibition effects on peroxidation of linoleic acid determined by ferric thiocyanate (FTC) method and on oxidative degradation of 2-deoxy-D-ribose in Fenton-type reaction system were dose-dependent. Athyrium acutipinulum Kodama (leaf and rood), Achyranthes japonica (Miq.) Nakai (seed), and Solidago virga-aurea var. gigantea Nakai (root) showed relatively high antioxidant activities in various systems.

  • This study was carried out to investigate the effect of dietary supplementation of Acanthopanax (A) senticosus and Eucommiaceae on the expression of lipogenic, myogenic and oxidative stress genes in broiler chickens. Birds were subjected (assigned) to one of the following 5 dietary treatments: control (CON), A. senticosus 0.5% (T1), 1.0% (T2), Eucommiaceae 0.5% (T3) and 1% (T4). Each treatment was replicated 8 times with 4 birds per replication, housed in 4 birds per cage. Birds were arranged according to randomized block design. Feeding trial was conducted from day 4 to 35th day of age. Liver and muscle tissues were collected for analysis. Broilers subjected to 1% A. senticosus had higher feed conversion ratio than the other treated birds whereas no significant differences were found in body weight, weight gain and feed intake. The gene expression levels of fatty acid synthase were not different among the treatments while the transcription factor $PPAR{\gamma}$ was highly expressed in Eucommiaceae but not in control and A. senticosus. The gene expression levels of myogenin were high in both A. senticosus and Eucommiaceae compared to control group. MyoD also showed high expression in treated groups furthermore, Eucommiaceae stimulated the expression of MyoD more than that of A. senticosus. The antioxidant gene expressions (SOD, CAT, SOD, GPX) generally were not much different among the treatments, however, SOD and GPX were stimulated in broilers consumed 1% Eucommiaceae diet. The result of this experiment showed that dietary supplementation of A. senticosus and Eucommiaceae in broiler may improve the antioxidant defence system through SOD and GPX without affect of growth performance in broilers.

  • Purpose : The purpose of this study was to find the optimum TE value for enhancing $T_2^{*}$ weighting effect and minimizing the SNR degradation and to compare the BOLD effects according to the changes of TE in 1.5T and 3.0T MRI systems. Materials and Methods : Healthy normal volunteers (eight males and two females with 24-38 years old) participated in this study. Each volunteer was asked to perform a simple finger-tapping task (sequential opposition of thumb to each of the other four fingers) with right hand with a mean frequency of about 2Hz. The stimulus was initially off for 3 images and was then alternatively switched on and off for 2 cycles of 6 images. Images were acquired on the 1.5T and 3.0T MRI with the FLASH (fast low angle shot) pulse sequence (TR : 100ms, FA : $20^{\circ}$, FOV : 230mm) that was used with 26, 36, 46, 56, 66, 76ms of TE times in 1.5T and 16, 26, 36, 46, 56, 66ms of TE in 3.0T MRI system. After the completion of scan, MR images were transferred into a PC and processed with a home-made analysis program based on the correlation coefficient method with the threshold value of 0.45. To search for the optimum TE value in fMRI, the difference between the activation and the rest by the susceptibility change for each TE was used in 1.5T and 3.0T respectively. In addition, the functional $T_2^{*}$ map was calculated to quantify susceptibility change. Results : The calculated optimum TE for fMRI was $61.89{\pm}2.68$ at 1.5T and $47.64{\pm}13.34$ at 3.0T. The maximum percentage of signal intensity change due to the susceptibility effect inactivation region was 3.36% at TE 66ms in 1.5T 10.05% at TE 46ms in 3.0T, respectively. The signal intensity change of 3.0T was about 3 times bigger than of 1.5T. The calculated optimum TE value was consistent with TE values which were obtained from the maximum signal change for each TE. Conclusion : In this study, the 3.0T MRI was clearly more sensitive, about three times bigger than the 1.5T in detecting the susceptibility due to the deoxyhemoglobin level change in the functional MR imaging. So the 3.0T fMRI I ore useful than 1.5T.

  • It is to be growing up the interest of community health affairs through visiting nursing care. The health medical treatment of Korea has been changed largely on the period. The juvenile population has decreased. This means that is has took the population consensus of advanced national organization to be increased by the old age. The transition of disease has changed from the contagious disease importance to the chronicity disease omportance because the domestic district population has experienced the sudden urbanization circumstance district population has experienced the sudden urbanization circumstance to be growing up $70\%$ of the whole population. When the nursing service has common function to be delivering from all direction to home, this study is getting the great important phase velocity in order to manage the kernel questional adult chronicity disease of health medical institution at the present age. (1) community over system or with people particularity (2) the first of third step medical treatments. The variety of medical treatments organization has quantity of the delivery manpower and specially between consumers and rdlated person. A qualitative difference is showed at the purpose to be seizing. That research related person is use at district health center in Seoul, by foundation on nurse registration book of H collage hospital and public health registration book. According the chronicity disease. age. and sex. nature agree-able standard 54 people took the content analysis on nurse registration book of total 108 people. The results of the study were as follows: 1. General background factors are houses or kind of medical facilities and number of patients in family. The first medical treatment is more patients than third medical treatment organization. The first medical treatment of economic environment os appering to be worse. 2. The chronicity disease frequency have been different speciality according to medical treatment organization. On case of the first medical treatment. Diabetes and High Blood Pressure were good but Cerebrum Vascular Accident(CVA) showed many for bed case. In addition. the number of family is comparative large exception of CVA on according for moving condition and health more than the first medical treatment. However. family condition. whole family percentage is decreasing preferably through the potential resource is increasing by the number of and the construction of family. The ability of real resource is considered to be low. 3. The average percentage of nurse service has appered to be differed two groups by the first step medical treatment(33.72 times) and third step medical treatment(45.70 times). However, the difference (the first step medical treatment and third step medical treatment) is to be limited to issue the medicine at the service. The condition of nurse care was the indirect nursing care. Supportiong area was to be related to volunteer service and administration support. 4. The various nursing care average percentage of the chronicity disease was increased by orders of Diabetes. High Blood Pressure. and CVA in examination result and the medical treatment. The indirect nursing care was also same. At third step medical treatment, orders of chronicity disease were same. The case of other area on service conditions were increased by order of Diabetes. High Blood Pressure, and CVA. However. it is never appearing the difference at bottleneck affairs nursing care. 5. When the visiting nursing care demand particularly. the average percentage of nursing care from the first step medical treatment that the time under a person is many more than the time over two people. However, there was no difference in statistic. Third step medical treatment is $49.81\%$ at the time under a person. The average nursing care service is appeared by more many when the visiting nursing care demand is a few by 12.83 at the time over two people. 6. By visiting nursing care percentage to be frequency that nursing care averaghe percentage and inter-relation are large. The related factor of the first medical treatment is 0.96. However, the related factor of third medical treatment has shown the decreased 0.49 for the condition of relation more than that. Therefore. the nursing care average percentage is related to the visiting times of a nurse. This result is be showing the obvious fact that the first step medical treatment is few more than third step medical treatment.
