  • Tactel(Nylon66) union fabrics were woven with the specification of 70d/34f nylon as warp for sport wear jacket. Weft yarn has three types; 100% cotton yarn, nylon core-spun yarn and nylon-polyurethane covering yarn as weft. Fabric structers were plain, twill and satin weave structure with the air jet loom. The mechanical properties of 8 fabrics were measured with KES-F and primary Hand Values and Total Hand Values were calculated. The results of the study were as follows: 1) There was little difference among LTs of N/CM fabric groups. RT of the fabrics with CM100's was bigger than that of fabrics with CM80's, resulting that the fabrics with CM100's have better formability. In terms of weaving structure, twill fabrics have shape deformation. 2) In comparison of RTs with weft yarn type, RT of N-PU covering yarn was the highest, followed by Nylon core-spun yarn and cotton yarn. Thus, the fabric with N-PU covering yarn has better stability of shape deformation. 3) Stretch yarn could express an excellent silhouette formation and twill and satin structures were better structure to make curvature on human form. 4) 2HG/G value of nylon core-spun fabrics was larger than that of N/C fabrics, but the silhouette formation of N/C fabrics was excellent. 5) The RC of N/PU was the highest, followed by N/P, and N/CM. 6) Koski of N/PU fabrics was the highest, Numeri of N/PU and N/Co-I were relatively higher than the others. THVs of N/CM-IV and N/CO-II were lower than the others, resulting that, twill structure was better than plain structure for a sport wear uses.

  • The aim of this study was to ana1yze T-cell lymphoma invasion and metastasis-inducing factor 1 (Tiam1) expression in 1ung cancer patients. A total of 204 patients with lung cancer tissue lesions were enrolled in the present study, along with 40 cases of normal lung tissue and 40 of normal fetal lung tissue. Tiam1 protein expression level was determined using intensity quantitative analysis, for comparison in lung cancer, metastatic, normal lung, and fetal lung tissue. The positive unit (PU) of Tiam1 was $13.5{\pm}5.42$ in lung cancer,$5.67{\pm}1.56$ in norma1 epithelial cells, and $5.89{\pm}1.45$ in fetal lung epithelial cells. The value in the lung cancer tissue was significantly higher than that in the normal lung tissue and the fetal lung tissue (P<0.01). The Tiam1 PU values with lymph node metastasis and without 1ymph node metastasis were $15.2{\pm}4.34$ and $12.5{\pm}4.23$, respectively, and the difference was statistically significant (P<0.05). The Tiam1 PU values in different tumor, nodes, metastasis (TNM) stages, III-IV period, and I-II phase were $14.7{\pm}4.14$ and $11.0{\pm}5.34$ (P<0.05). A correlation was found between Tiam1 expression and the age of patient, tumor size, tumor type, and tumor differentiation. Tiam1 protein expression in the lung tumor tissue is significantly higher than that in the normal lung tissue and fetal lung tissue. Tiam1 expression may be closely related to lung cancer development and metastasis.

  • Objectives : The source is from the flower of Carthamus tinctorius L., family Compositae. It is used in clinical medicine to promote blood circulation, remove blood stasis, promote menstruation and alleviate pain. In the present study, we investigated the genome wide analysis of Carthami Flos on the intra-cranial hemorrhage(ICH) model. Methods : ICH in rat was induced by injection of collagenase type IV and Carthami Flos extract(CFe) was administered orally. The molecular profile of cerebral hemorrhage in rat brain tissue was measured using microarray technique to identify up- or down- regulated genes in brain tissue. Results : Expression profile showed that diverse genes were up- or down-regulated by ICH induction. Administration of CFe restored the expression level of some of altered genes by ICH to normal expressional level. Interestingly, these recovered genes by CFe were involved in the same biological pathways which were significantly activated or suppressed by ICH. Conclusion : The above results might explain the therapeutic mechanism of CFe on ICH. Further, by analyzing interaction network, core genes was identified which could be key molecular targets of CFe against ICH.

  • This experiment was conducted to evaluate the effect of supplementing a fat diet with selenium (Se) and vitamin E on performance of cows, blood antioxidant status and milk fatty acid composition. Sixty-three lactating Holstein cows were randomly divided into seven groups of nine cows each and each group was fed one of the following diets: i) a basal diet (control); ii) a basal diet with 0.15 mg Se/kg DM (LSe); iii) a basal diet with 0.3 mg Se/kg DM (HSe); iv) a basal diet with 5,000 IU/cow d vitamin E (LVE); v) a basal diet with 10,000 IU/cow d vitamin E (HVE); vi) a basal diet with 0.15 mg Se/kg DM and 5,000 IU/cow d vitamin E (LSeVE); vii) a basal diet with 0.3 mg Se/kg DM and 10,000 IU/cow d vitamin E (HSeVE). Milk fat percentage and conjugated linoleic acid (CLA) yield in HVE and HSeVE diets increased (p<0.05) compared with the control diet. In milk fat, dietary supplementation of Se tended to increase the proportion of the sum of unsaturated fatty acids (UFA) and significantly decreased (p<0.05) the proportion of the sum of saturated fatty acids (SFA). In addition, compared with the control, thiobarbituric acid reactive substances (TBARS) content was lower and glutathione peroxidase (GSH-Px) was higher when fat diets were supplemented with Se. Our data showed that supplementation with Se and/or VE improved these nutrients in blood and milk. The results indicated that fat diets supplemented with Se improved both antioxidant status in blood and fatty acids in milk fat, and fat diets supplemented with vitamin E alleviated milk fat depression. Therefore, the combination of Se and vitamin E caused synergistic effects on the nutritional quality of milk fat and performance of cows fed a fat diet.

  • Background: Studies of morphological variation within and among populations provide an opportunity to understand local adaptation and potential patterns of gene flow. To study the evolutionary divergence patterns of Schlegel's Japanese gecko (Gekko japonicus) across its distribution, we analyzed data for 15 morphological characters of 324 individuals across 11 populations (2 in China, 4 in Japan, and 5 in Korea). Results: Among-population morphological variation was smaller than within-population variation, which was primarily explained by variation in axilla-groin length, number of infralabials, number of scansors on toe IV, and head-related variables such as head height and width. The population discrimination power was 32.4% and in cluster analysis, populations from the three countries tended to intermix in two major groups. Conclusion: Our results indicate that morphological differentiation among the studied populations is scarce, suggesting short history for some populations after their establishment, frequent migration of individuals among the populations, and/or local morphological differentiation in similar urban habitats. Nevertheless, we detected interesting phenetic patterns that may predict consistent linkage of particular populations that are independent of national borders. Additional sampling across the range and inclusion of genetic data could give further clue for the historical relationship among Chinese, Japanese, and Korean populations of G. japonicus.

  • Design and safety assessment of fuel pins for application in innovative Generation IV fast reactors calls for a dedicated nuclear fuel modelling and for the extension of the fuel performance code capabilities to the envisaged materials and irradiation conditions. In the INSPYRE Project, comprehensive and physics-based models for the thermal-mechanical properties of U-Pu mixed-oxide (MOX) fuels and for fission gas behaviour were developed and implemented in the European fuel performance codes GERMINAL, MACROS and TRANSURANUS. As a follow-up to the assessment of the reference code versions ("pre-INSPYRE", NET 53 (2021) 3367-3378), this work presents the integral validation and benchmark of the code versions extended in INSPYRE ("post-INSPYRE") against two pins from the SUPERFACT-1 fast reactor irradiation experiment. The post-INSPYRE simulation results are compared to the available integral and local data from post-irradiation examinations, and benchmarked on the evolution during irradiation of quantities of engineering interest (e.g., fuel central temperature, fission gas release). The comparison with the pre-INSPYRE results is reported to evaluate the impact of the novel models on the predicted pin performance. The outcome represents a step forward towards the description of fuel behaviour in fast reactor irradiation conditions, and allows the identification of the main remaining gaps.

  • The present article deals with the concept 'ekayāna' as the spirit of the times in the period of Unifying War in Shilla, which is embodied in the thought of Wonhyo and Euisang. This article is divided into five sections. Section I introduces the background of research history regarding the spirit of the age during the Unifying War, and explaines the reason why we adopted two thinkers such as Wonhyo and Euisang, especially the concept 'ekayāna' of the two as a subject for inquiry. Section II discusses on the hermeneutical difference between the Chinese Faxiang sect and Wonhyo regarding the interpretation of one passage from Saṃdhinirmocana-Sūtra, in which the relation between ekayāna and triyāna is explained. It is noteworthy that Faxiang sect places emphasis on the differentiation of triyāna, but Wonhyo gives emphasis to equality of ekayāna. Section III refers to the hermeneutical horizons of Wonhyo which is connoted in the interpretation of Saṃdhinirmocana-Sūtra, especially focusing on the concept 'ekayāna'. Here we can make a conclusion as follows; Firstly, the 'ekayāna' in Wonhyo is immanent in 'triyāna' and at the same time transcendental from 'triyāna', so to speak 'com-transcendetal' with 'triyāna'. Secondly, there is inseparable and unmixable relation between 'ekayāna' and beings. In another words, 'ekayāna' is śūnyatā. Thirdly, 'ekayāna' is a kind of universal truth(普法 pŭ fă) in that it offers the benefit to open and develop the immanent buddhadhātu of all living lives. In addition to Wonhyo's thought on ekayāna, section IV refers to the concept 'ekayāna' of Euisang. On Euisang, 'ekayāna' is 'the perfect teaching(圓敎 yuán jiào)' and 'pratītyasamutpāda'. From this point of view, we can conclude that the thought on ekayāna between the two, Wonhyo and Euisang is not different, and completely coherent. As a result, as it is concluded in section V, it is also clear that ekayāna has 'com-transcendental' relation to triyāna. Therefore we can safely make a conclusion that the spirit of the times in the period of Unifying War in Shilla among the leading thinkers is the vision for 'com-transcendency'.

  • Status on the spent nuclear fuel management policy and R&D plan of the major countries is surveyed. Also the prospect of the future R&D plan is suggested. Recently so-called fuel cycle nations, which have the reprocess policy of the spent fuel, announced new spent fuel management policy based on the advanced fuel cycle technology. The policy is focused to transmute highly radioactive material and material having a very long half-life, and to recycle the Pu and U contained in the spent fuel. In this way the radio-foxily of the spent fuel as well as the amount of the high level waste to be eventually disposed can greatly be reduced. Most of countries selected the wet process as a primary option for the treatment of the spent fuel since the advanced wet process, which is based on the existing PUREX process, looks more feasible as compared with the dry process. The wet process, however, is much more sensitive in terms of proliferation-resistance compared with the dry process. The pure Pu can easily be obtained by simply modifying the process. On the other hand the pure Pu can not be extracted in the dry process based on the high temperature molten salt process such as a pyroprocess. Even though the pyroprocess technology is very premature, it has a great merit. Thus it is necessary for Korea to have a long term strategy for pursuing a spent fuel treatment technology with a proliferation resistance and a great merit for the GEN-IV fuel cycles. Pyroprocess is one of the best candidates to satisfy these purposes.
