This study is the research of middle school students' sports participation and the contact into computer lewdness. The followings are conclusions. 1. The positive students participated in sports have much experience in the computer lewdness. The positive students are more sensitive than negative students in sexual behavior. The sexual response after they watch computer lewdness was positive. The positive students were more progressive than negative students in the sexual consciousness. 2. Most of the students in the response of research question have experiences of contact into the computer lewdness, the boys were exposed more than girls. They watched the computer lewdness with their friends but they don't watch it habitually. The realities of computer lewdness are inclined to recognize negatively and extensively by mass communication. 3. Their sexual behaviors when they watched the lewdness were low point below the average, the boys were more positive than girls. In the experience of acquaintance , the girls were more positive than boys. But most of the students had no sexual experience. 4. The sexual response when the students watch the scene of the lewdness was low below the average point, the girl students are negative than boys and some of the boys have the sexual desire. These present state are the common things that they have in the adolescence and they are not only because computer lewdness. Therefore we need many kinds of sex education in order not to have disgust in sex. 5. In the response of sexual consciousness, most of the students are interested in lower than average point. They are conservative and negative. The positive students in sports are more progressive than negative students.

Jun-Jie LIU,Liu-Yang LU,Hui-Hui LIU,Ya-She LI,Xu SU,Bai-Zhong ZHANG,Xi-Ling CHEN 한국곤충학회 2019 Entomological Research Vol.49 No.8

The greenbug, Schizaphis graminum Rondani is a major pest species of wheat crops. In this study, a transcriptome sequencing, and the expression of the 12 genes related to insecticide resistance were conducted in S. graminum. The sequencing and subsequent bioinformatics analysis outputed 46,593 unigenes, among which 28,289 unigenes were annotated to corresponding functions by blasting with high homologous genes in database, giving annotation rate of 60.72%. To gain insight into the mechanism of insecticide resistance, the expression of the 12 genes related to insecticide resistance for S. graminum was investigated. The expression level of aminopeptidase N (AN), cytochrome P450 (CYP), acetylcholinesterase 1 (AC), catalase (CAT), cytochrome c oxidas (CCC), GABA receptor (GABA), glutathione S-transferase (GST) were highest in the apterous nymphs among different developmental stages; The expression level of AN, CBL, CYP, CA, SD, and GST were relatively more abundant in the abdomen compared to head and throax. The results could give out the key information about the relationship between the expression of these genes in different developmental stages, tissues, treatments and metabolism of insecticides. These genes that were co-up-regulated significantly in third instar nymphs of S. graminum induced by imidacloprid, were consistent with their putative involvement in insecticide resistance. This provides most comprehensive transcriptome data for S. graminum to further study and managenment.

Development and validation of FRAT code for coated particle fuel failure analysis

Li Jian,She Ding,Shi Lei,Sun Jun 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.11

TRISO-coated particle fuel is widely used in high temperature gas cooled reactors and other advanced reactors. The performance of coated fuel particle is one of the fundamental bases of reactor safety. The failure probability of coated fuel particle should be evaluated and determined through suitable fuel performance models and methods during normal and accident condition. In order to better facilitate the design of coated particle fuel, a new TRISO fuel performance code named FRAT (Fission product Release Analysis Tool) was developed. FRAT is designed to calculate internal gas pressure, mechanical stress and failure probability of a coated fuel particle. In this paper, FRAT was introduced and benchmarked against IAEA CRP-6 benchmark cases for coated particle failure analysis. FRAT's results agree well with benchmark values, showing the correctness and satisfactory applicability. This work helps to provide a foundation for the credible application of FRAT.

Kidney-sparing Management Versus Nephroureterectomy for Upper Tract Urothelial Carcinoma: a Systematic Review and Meta-analysis

Luo, You,She, Dong-Li,Xiong, Hu,Fu, Sheng-Jun,Yang, Li Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.14

Purpose: To evaluate and update evidence for prognostic effects of kidney-sparing (KS) management and nephroureterectomy (NU) for upper tract urothelial carcinomas. Materials and Methods: Pubmed, Embase and the Cochrane Library were retrieved for the identification of comparative studies of kidney-sparing procedure and nephroureterectomy for upper tract urothelial carcinoma prior to December 2014. The data were extracted independently by 2 reviewers and the quality of the included studies was assessed. Review Manager 5.3 and STATA 13 were used to perform the meta-analysis. Results: Twenty-three observational studies including 1,587 KS and 3,996 NU were evaluated. The results of the meta-analysis showed that nephroureterectomy had no significant benefit with regard to intravesical recurrence (IRFS), metastasis (MFS), cancer specific survival (CSS) and overall survival (OS) except the total tumor recurrence (RFS) when compared with kidney sparing management. The respectively pooled outcomes were HR 1.36 (0.69-2.68, P=0.38) for IRFS, 1.09 (0.59-2.01, P=0.78) for MFS, 1.17 (0.77-1.79, P=0.47) for CSS, 1.50 (0.90-2.48, P=0.12) for OS and 1.61 (1.03-2.51, P=0.04) for RFS. Conclusions: On the whole, kidney-sparing management had equivalent prognostic effect on upper tract urothelial carcinoma as the standard nephroureterectomy except in tumor recurrence. However, the results should be interpreted with caution for lack of stage and grade stratification and multi-center randomized controlled trials are still needed to verify our results.

Enhanced β-carotene production by Rhodotorula glutinis using high hydrostatic pressure

Sui-Lou Wang,Jun-She Sun,Bei-Zhong Han,Xiao-Zong Wu 한국화학공학회 2008 Korean Journal of Chemical Engineering Vol.25 No.3

High hydrostatic pressure (HHP) technology was used for improving the ability of β-carotene biosynthesis of Rhodotorula glutinis R68. After the treatments of five repeated cycles at 300MPa for 15 min, the barotolerant mutant PR68 was obtained. After 72 h of culture, the biomass of mutant PR68 was 21.6 g/L, decreased by 8.5% compared to the parent strain R68, but its β-carotene production reached 19.4 mg/L, increased by 52.8% compared to the parent strain R68. The result of restriction fragment length polymorphism analysis suggested that mutant strain PR68 was likely to change in nucleic acid level, and thus enhanced β-carotene production in this strain was a result of gene mutation induced by HHP treatment. HHP technology seems a promising approach for improving industrial microbes

Liu Xuemei,Min Jie,She Bin,Chen Yang,Li Jun,Huang Lei,Chen Ju,Luo Ai,Mei Yang,Li Ting,Wu Yanqing,Chen Daohong,Hongli Zhong,Liu Wei,Mao Bing,Jiang Hongli 한국한의학연구원 2023 Integrative Medicine Research Vol.12 No.3

Background: Binafuxi granules are a traditional Uighur medicine (TUM) for treating the common cold with fever. However, high-quality clinical studies supporting its efficacy and safety are lacking. Methods: In this multicenter, randomized, double-blind, placebo-controlled, phase II clinical trial, patients with common cold and fever were randomly assigned to a high-dose group, low-dose group, and placebo group in a 1:1:1 ratio. Outcomes were time to fever relief, time to fever clearance, proportion of afebrile patients, time to symptom disappearance, rate of symptom disappearance, effective rate, emergency drug usage and safety assessment. Results: A total of 235 patients were recruited. Of these, 234 were included in the full analysis set (FAS), and 217 were included in the per-protocol set (PPS). In the FAS analysis, the median time to fever relief was 6.00 h, 5.54 h and 10.65 h (P = 0.31) in the high-dose group, low-dose group and placebo group, respectively. The median time to fever clearance was 18.29 h, 20.08 h and 25.00 h (P = 0.0018), respectively, and the proportion of afebrile patients was 92.4%, 89.7% and 71.4% (P = 0.0002), respectively. There was a significant difference in the disappearance time and disappearance rate of all symptoms and of individual symptoms. No serious adverse events were found. Conclusions: Binafuxi granules can dose-dependently shorten the fever course and improve clinical symptoms in patients suffering from the common cold with fever.

A κ-Carrageenase from a Newly Isolated Pseudoalteromonas-like Bacterium, WZUC10

Mao-hong Zhou,Jian-she Ma,Jun Li,Hai-ren Ye,Ke-xin Huang,Xiao-wei Zhao 한국생물공학회 2008 Biotechnology and Bioprocess Engineering Vol.13 No.5

A bacterial strain able to produce k-carrageenase, designated WZUC10, was isolated from a live specimen of the red alga Plocamium telfairiae collected in the East China Sea. The phylogenetic evidence and phenotypic features indicate that this strain belongs to the genus Pseudoalteromonas. WZUC10 requires NaCl for growth and k-carrageenan to induce k-carrageenase synthesis; galactose and lactose do not induce it. The optimal growth temperature is 23~27°C. The secreted enzyme, which has a molecular mass of 45 kDa, breaks down k-carrageenan into k-neocarratetraose sulfate and larger oli-gosaccharides with a repeating β-D-Galp4S-(1→4)-α-D-AnGalp structure, but cannot degrade k-neocarratetraose sulfate or k-neocarrahexaose sulfate into k-neocarrabiose sulfate. The enzyme retains 90% of its activity after 2 h at 40°C and is com-pletely inactivated after 7.5 min at 70°C. The enzyme’s optimal temperature is 30°C and its optimal pH is 7.5. The enzyme-catalyzed reaction follows Michaelis-Menten kinetics, with the Michaelis constant (Km) and the turnover number (k) being 0.015 mM and 125 s-¹, respectively. WZUC10 produces 50 U/mL k-carrageenase after cultivation at 25°C for 35 h on a me-dium containing 80 g/L glucose, 5 g/L corn steep liquor, 3 g/L k-carrageenan, and 15 g/L NaCl. k-Neocarratetraose sulfate was prepared simply with precipitation by ethanol:water (5:1, v/v).
