In recent years, the research in porous metal got rapid development in China, especial in Northwest Institute for Non-ferrous Metal Research (NIN). Many porous metals with different raw material and different shapes were developed, which successfully employed in many fields. We believe we will earn more rapid development in the future.

This paper investigates generalizations of weakening-free uninorm logics not assuming associativity of intensional conjunction (so called fusion) &, as non-associative fuzzy-relevance logics. First, the strong t-associative monoidal uninorm logic StAMUL and its schematic extensions are introduced as non-associative propositional fuzzy-relevance logics. (Non-associativity here means that, differently from classical logic, & is no longer associative.) Then the algebraic structures corresponding to the systems are defined, and algebraic completeness results for them are provided. Next, predicate calculi corresponding to the propositional systems introduced here are considered.

In this note we construct an anti-symplectic involution on the non-$K\ddot{a}hler$, symplectic 4-manifold which is constructed by Thurston and show that the quotient of the Thurston's 4-manifold is not symplectic. Also we construct a non-$K\ddot{a}hler$, symplectic 4-manifold using the Gomph's symplectic sum method and an anti-symplectic involution on the non-$K\ddot{a}hler$, symplectic 4-manifold.

In this paper we study ${\omega}$-limit sets and attraction of non-autonomous discrete dynamical systems. We introduce some basic concepts such as ${\omega}$-limit set and attraction for non-autonomous discrete system. We study fundamental properties of ${\omega}$-limit sets and discuss the relationship between ${\omega}$-limit sets and attraction for non-autonomous discrete dynamical systems.

We prove that the two-step flag variety 𝓕ℓ(1, n; n+1) carries a non-displaceable and non-monotone Lagrangian Gelfand-Zeitlin fiber diffeomorphic to S³ × T^2n-4 and a continuum family of non-displaceable Lagrangian Gelfand-Zeitlin torus fibers when n > 2.

The purpose of this study was to assess comsumer preferences and perception of Korean foods in Koreans and non-Koreans residing in Korea. Exactly 79 customers (28 Koreans, 51 non-Koreans) were surveyed with questionnaires in English and Korean. Data were analyzed using the SPSS statistical package (21.0) and ${\chi}^2$-test. Subjects were of various nationalities, including China (37.3%), Philippines (19.6%), Japan (17.7%), USA (11.8%), Uzbekistan (3.9%), Nepal (2.0%) and Nigeria (2.0%). The representative food was Kimchi and favorite Korean foods were Kimchi, Bulgogi, Bibimbap, Galbijjim etc. Koreans reported that the main advantages of Korean food were its 'home-made style', but non-Koreans reported 'health functionality'. In terms of disadvantages, non-Koreans consumers ranked 'unsanitary eating style without individual plates' as the biggest problem while Koreans ranked 'table setting at a time'. Factors 'complicated cooking method', 'spicy taste' and 'salty taste' were also reported disadvantages. Survey participants were asked what was the most important for the globalization of Korean food. Most non-Korean participants listed 'health functionality' and 'traditionalism' (p<0.05).

포도 품질을 높일 수 있고, 숙기 판단 노력을 절감할 수 있는 봉지 재료를 선발하고자 1997년부터 1999년까지 3년간에 걸쳐 충청북도 농업기술원 옥천포도시험장에서 시험한 결과를 요약하면 다음과 같다. 봉지내의 광 투과율은 종이 봉지에 비하여 부직포 및 무적비닐 이용 봉지에서 11∼65%가 높았으나, 무적비닐 천공 상면 50% 흰색 페인팅 봉지는 25% 낮았다. 과립중은 종이봉지에 비하여 부직포와 무적비닐이용 봉지에서 무거웠으며, 무적비닐 천공 상면 50% 흰색 페인팅 봉지는 열과, 탈립 및 부패과가 심하여 조사가 불가능하였다. 숙기는 종이봉지에 비하여 부직포와 무적비닐 이용 봉지에서 1∼4일 빨랐다. 당도는 부직포와 무적비닐 이용 봉지에서 높은 경향이었으나, 산도는 상반된 경향이었다. 착색정도는 종이 봉지에 비하여 부직포와 무적비닐 이용 봉지에서 빨랐으며, 이들 봉지간에는 착색 정도는 맥반석 혼합 부직포와 무적비닐+부직포 봉지에서 빨랐으나, 적숙기로 가까워질수록 부직 포봉지에서 빨랐다. 비정상 과립율은 종이와 부직포 봉지는 5.4∼7.0%로 낮았으나, 무적비닐 이용 봉지는 16.6∼100%로 높았다. 외관상품질은 부직포와 맥반석 혼합 부직포에서 지수 9.0으로 가장 좋았으나, 무적비닐 천공 상면 50% 흰색 페인팅 봉지는 지수 1.0으로 가장 불량하였다. 숙기 판단 소요시간은 종이(17.4시간/10a)에 비하여 부직포와 무적비닐 이용 봉지에서 74∼93% 절감되었다.

Purpose - The purpose of this paper is to examine the determinants of non-bank depository institutions (non-bank financial corporations) lending to firms. The paper aims to contribute to the existing literature by providing empirical evidence from firm-level data and unveiling factors related to access to non-bank financial corporations by firms. Research design, data, and methodology - We used the data on borrowing by firms from CRETOP from years 2008 to 2011. Using the manufacturing industry, we examined what firm-level characteristics explained the increase in borrowing from non-bank financial corporations rather than the banks. Results - Analyzing the firm-level data from 2008 to 2011, we found that firms were more likely to borrow from non-bank financial insti­tutions as the size of the firm increases, implying that large firms have more access to non-bank financing than small and medium-sized firms. In addition, it also showed that small and medium-sized firms moved to non-bank financial corporations for loans. Conclusion - Non-bank depository institutions are not a sub­stitute for bank lending to firms. More specifically, they replace bank lending to firms mostly for large firms rather than small and medium-sized firms. Also, collateral and other firm-level characteristics do not matter in accounting for non-bank lending to firms.

This study focused on the variations in the non-coding sequences between ctxB and rstR of various CTX phages. The non-coding sequences of CTX-1 and CTX-cla are phage type-specific. The length of the non-coding region of CTX-1 and CTX-cla is 601 and 730 nucleotides, respectively. The non-coding sequence of CTX phage could be divided into three regions. There is a phage type-specific Variable region between two homologous Common regions (Common regions 1 and 2). The non-coding sequence of RS1 element is similar to CTX-1 except that Common region 1 is replaced by a short RS1-specific sequence. The non-coding sequences of CTX-2 and CTX-cla are homologous, indicating the non-coding sequence of CTX-2 is derived from CTX-cla. The non-coding region of CTX-O139 is similar to CTX-cla and CTX-2; however, it contains an extra phage type-specific sequence between Common region 2 and rstR. The variations in the non-coding sequences of CTX phages might be associated with the difference in the replication efficiency and the directionality in the integration into the V. cholerae chromosome.
