Objective: To compare multiparametric magnetic resonance imaging (MRI) features of intraductal carcinoma of the prostate (IDC-P) with those of prostatic acinar adenocarcinoma (PAC) and develop prediction models to distinguish IDC-P from PAC and IDC-P with a high proportion (IDC ≥ 10%, hpIDC-P) from IDC-P with a low proportion (IDC < 10%, lpIDC-P) and PAC. Materials and Methods: One hundred and six patients with hpIDC-P, 105 with lpIDC-P and 168 with PAC, who underwent pretreatment multiparametric MRI between January 2015 and December 2020 were included in this study. Imaging parameters, including invasiveness and metastasis, were evaluated and compared between the PAC and IDC-P groups as well as between the hpIDC-P and lpIDC-P subgroups. Nomograms for distinguishing IDC-P from PAC, and hpIDC-P from lpIDC-P and PAC, were made using multivariable logistic regression analysis. The discrimination performance of the models was assessed using the receiver operating characteristic area under the curve (ROC-AUC) in the sample, where the models were derived from without an independent validation sample. Results: The tumor diameter was larger and invasive and metastatic features were more common in the IDC-P than in the PAC group (P < 0.001). The distribution of extraprostatic extension (EPE) and pelvic lymphadenopathy was even greater, and the apparent diffusion coefficient (ADC) ratio was lower in the hpIDC-P than in the lpIDC-P group (P < 0.05). The ROC-AUCs of the stepwise models based solely on imaging features for distinguishing IDC-P from PAC and hpIDC-P from lpIDC-P and PAC were 0.797 (95% confidence interval, 0.750-0.843) and 0.777 (0.727-0.827), respectively. Conclusion: IDC-P was more likely to be larger, more invasive, and more metastatic, with obviously restricted diffusion. EPE, pelvic lymphadenopathy, and a lower ADC ratio were more likely to occur in hpIDC-P, and were also the most useful variables in both nomograms for predicting IDC-P and hpIDC-P.

The types of sixth industry to aim of boosting agriculture and rural areas and Korea's sixth industrial cases(Local community, production-centric, distribution-centric, dine out-centric, treatment-centric, export-centric) and competitiveness measures through Japan and China. Specifically, the competitiveness through the sixth industrial case is to maximize added value through cooperation between communities and to coexist among local residents. Efforts are needed not only to create jobs for the elderly but also to gain consumer confidence, and various measures should be sought to establish a cooperative system. In addition, as customers ' needs change rapidly in the smart age, the life cycle of goods and services is getting extremely faster. Therefore, the sixth industry is expected to be able to predict changes in customer and market trends quickly and accurately, thus making efforts to bring new products and services to market more necessary and contributing to achieving rural activation.

The objective of this study is to investigate the sensory quality attributes for the development of soy sauce containing Cheongmirae (Smilax china) root. Aqueous extracts of Cheongmirae root and Cheongmirae-soy sauce were used for determining the antioxidant effect by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and sensory evaluation. Chengmirae-soy sauce was prepared by mixing Chengmiae extract (50%) and soy sauce (50%). Cheongmirae extract and Cheongmirae-soy sauce had strong DPPH scavenging effects, compared to that of general soy sauce. In sensory analysis, low intensities of smell, taste and overall preference were observed in Cheongmirae root extract. Various seasoning items, such as anchovy, dried-pollack, katsuobushi, shiitake, radish, and kelp, were used to determine the suitable type of soy sauce containing Cheongmirae root extract. The anchovy-kelp-radish and anchovy-shiitake-kelp-radish among the seasoning items were well-matched with Cheongmirae root extract. From these results, soy sauce containing Cheongmirae root extract may be used as a soup seasoning for Korean style noodles.

Purpose: This study was to investigate depression in Korean-Chinese elder living in the Yanbian Korean Autonomous Prefecture in China. Methods: A cross-sectional community-based survey was conducted using face to face private interviews for elders aged over 59, who have been dwelling in the Yanbian Korean Autonomous Prefecture. The samples consisted of 183 Korean-Chinese and 182 Han-Chinese with the latter as a reference group. Data were collected from August 25 to September 20, 2011 and analyzed with the SPSS 18.0 program. The GDS (Geriatric Depression Scale) was used to measure elderly depression in the subjects. Results: In Korean-Chinese, the rate of depression was higher in those who had lower educational levels, and were economically supported by the government. And those who had depression showed lower scores in Chinese language proficiency, health status, and social supports, and had more chronic diseases. Factors having effects on Korean-Chinese elderly depression included perceived health status and subjective support. Conclusion: According to the results, for preventing the depression of Korean-Chinese, it is necessary to develop health management programs and social support networks, which were easy to approach.

When a failure occurs in active distribution system, it will be isolated through the action of circuit breakers and sectionalizing switches. As a result, the network might be divided into several connected components, in which distributed generations could supply power for customers. Aimed at decreasing customer interruption cost, this paper proposes a theoretically optimal island partition model for such connected components, and a simplified but more practical model is also derived. The model aims to calculate a dynamic island partition schedule during the failure recovery time period, instead of a static islanding status. Fluctuation and stochastic characteristics of the renewable distributed generations and loads are considered, and the interruption cost functions of the loads are fitted. To solve the optimization model, a heuristic search algorithm based on the hill climbing method is proposed. The effectiveness of the proposed model and algorithm is evaluated by comparing with an existing static island partitioning model and intelligent algorithms, respectively.

In the past 10 years, there have been lots of misuses of the trademark system in China. For example, some Chinese companies have registered same or similar oversea's well-known trademark as a prior rights holder, and oversea's companies lost a chance to register their own trademarks or commence cases to acquire their own trademark determination in China. So Chinese government revised Chinese Trademark Law in 2014 to remedy these mistakes. Article 30 is intended to crack down on preemptive registration and compensate for the possible unfair consequences resulted from the principle of prior registration. Under the principle of prior registration, only where the unregistered trademarks of prior use have certain influence, and where the applicant of latter applied trademark knows or should know the prior trademark and the applicant has the bad faith of obtaining unjustified interests from goodwill of such unregistered marks, it shall be curbed by Article 30. Furthermore, trademark oppositions could be filed by anybody previously. Under the revised Trademark Law Article 44, oppositions based on absolute grounds can still be filed by anyone, but oppositions based on other available grounds can only be filed by a prior rights holder or a materially-interested party with undefined but similar to the standing requirement for filing nullities under Article 41 of the old law, and likely intended to cover trademark licensees and successors.

The effect of dietary iodine and selenium supplementation, alone or in combination, on peripheral blood lymphocyte function was determined in laying hens. Eight-hundred-and-sixty-four New-Loman laying hens were randomly allotted into 12 dietary treatments with different inclusion levels of iodine (0, 0.1 and 0.2 mg/kg), selenium (0, 0.05, 0.1 and 0.2 mg/kg) or their combinations for 24 weeks. The lipopolysaccharide (LPS) stimulation index, concanavalin A (ConA) stimulation index, peroxide enzyme activity and phagocytosis to neutral red particles were tested. There were significant differences in LPS stimulation index, ConA stimulation index, peroxide enzyme activity and phagocytosis to neutral red particles in different iodine or selenium supplementation levels (p<0.05). The highest iodine and selenium supplementation both resulted in highest LPS-/ConA-stimulation indices (p<0.05). However, when iodine was lower than 0.2 mg/kg, the additional effect of different levels of selenium did not always result in significant differences in these indices. The results indicated that iodine and selenium may affect immunity in laying hens and, when the iodine level in the laying hen is lower than 0.2 mg/kg, a selenium allowance higher than 0.1 mg/kg may be necessary to improve immunity.

Satellite synthetic aperture radar (SAR) images from 1995 to 2001 and field measurements of sea surface wind, sea state, and vertical stratification are used for statistical analyses of internal wave (IW) occurrence and SAR imaging conditions in the northern South China Sea (NSCS). Latitudinal distribution of IW packets shows that 22% of IW packets distributed in the east of $118^{\circ}E$ and 78% of IW packets in the west of $118^{\circ}E$. The yearly distribution of IW occurrence frequencies reveals an interannual variability. The monthly SAR-observed IW occurrence frequencies show that the high frequencies are distributed from April to July and reach a peak in June. The low occurrence frequencies are distributed in winter from December to February of next year. These statistical features are explained by solitary wave dynamics.

Chinese literature once had its splendid era in the Tang and Song Dynasties culminating in Tang poetry and influencing the literatures of its neighboring countries. However, during the past centuries, it has largely been "marginalized" on the map of world literature. On the one hand, large numbers of foreign literary works, especially those from Western countries, have been translated into Chinese, exerting a huge influence on the formation of a sort of modern Chinese literary tradition. On the other hand, few contemporary Chinese literary works have been translated into the major foreign languages. With the help of the rise and flourishing of comparative literature, contemporary Chinese literature has been moving toward the world and had its own Nobel laureate. The author, after analyzing the reasons why Chinese literature has been "marginalized," argues that Chinese literature will develop steadily in the age of globalization. Globalization in China has undergone three steps: first, it has made China passively involved in this irresistible trend; second, the country has then quickly adapted itself to this trend; and third, China has started to play an increasingly leading role in the first decade of the present century. In this way, contemporary Chinese literature and comparative literature studies will steadily develop with the help of the "Belt and Road" initiative.
