The aspects and satisfaction on university foodservice were investigated to provide basic information for better foodservice in university by questionnaires. The survey was conducted in Daejon, and data were analyzed by SAS. Although 87.3% of subjects were under foodservice, only 2.0% of them preferred the foods served in university. The most favorite reason for foodservice was indicated as no need on lunch bag(31.1%) and frendship of classmates(25.5%). The most unfavorite reason for foodservice was indicated as bad taste of foods(68.7%) or many dislike foods(13.2%), also dirty eating place(7.7%). The subject liked ssalbap, baechu kimchi, beef foods. The acceptance about kongbap, yulmu kirnchi, beef products was higher in men than women(p<0.05). The preference of mieokkuk was higher in women and that of beef soup was higher in men(p<0.05). The degree of satisfaction was lower in men than in women about the amount of foods(p<0.001). Also the degree of satisfaction was lower in women than in men about sanitary condition of eating place. 54.6% of them had taken the unwanted materials in foods and 3% of them experienced the deteriorated food. The results suggest that food preference of subjects should be considered in meal planning and various cooking method should be utilized to enhance taste of foods for better foodservice. Also, the importance of various foods intake must be periodically and continuously taught to them through nutrition education.

Wang, Nan-Ya,Wang, Cong,Li, Wei,Wang, Guan-Jun,Cui, Guo-Zhen,He, Hua,Zhao, Heng-Jun Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.4

Purpose: Alpha-fetoprotein (AFP), Lens culinaris agglutinin-reactive fraction of AFP (AFP-L3), and Golgi protein 73 (GP73) levels have been widely used as tumor markers for the diagnosis of hepatocellular carcinoma (HCC). The aim of this study was to investigate whether these tumor markers could be used to monitor short-term treatment response and recurrence of HCC in patients undergoing radiofrequency ablation (RFA). Methods: Between July 2012 and July 2013, 53 consecutive patients with newly diagnosed HCC were prospectively enrolled in this study. Among these, 32 patients underwent RFA, after which they were followed up prospectively at the First Hospital of Jilin University in China. Results: AFP, AFP-L3, and GP-73 values pre-RFA were not associated with tumor size, whereas AFP and GP-73 levels tended to be associated with tumor number, the presence of vascular invasion, deterioration of liver function, advanced-stage disease, and a poor performance status. GP-73 levels were dramatically elevated in the patients with hepatitis C-associated HCC. Neither pre-RFA nor 1-month post-RFA tumor marker values were associated with short-term outcome. The short-term recurrence rate of AFP-positive patients measured 1 month post-RFA was obviously higher than that of AFP-negative patients. Conclusions: AFP and GP-73 values were associated with clinical variables representing tumor growth and invasiveness, and the AFP value measured 1 month post-RFA was a strong predictor of short-term recurrence in patients with HCC.

한중 자기반의어의 의미 양상과 해석

王楠楠(Wang, Nan-nan) 담화·인지언어학회 2017 담화와 인지 Vol.24 No.2

This paper discusses semantic aspects of autoantonym and its interpretation in order to define semantic properties of autoantonym which exists between Korean and Chinese in the perspective of cognitive linguistics. The results are as follows: First, it pointed out the similarities and differences between autoantonym and antonym, and limit the scope of autoantonym. Second, the semantic aspects of autoantonym are largely divided into ‘directional opposition’, ‘scale opposition’, and ‘complementary opposition’. Through the contrast between Korean and Chinese, it showed that there are some autoantonyms which correspond to each other, whereas there are most autoantonyms which cannot correspond to each other. Third, the creation of autoantonym is supported by internal causes of language such as ‘contagion’, and external causes of language such as encyclopedic knowledge about reference, human’s cognitive tendencies, cultural background of research language, etc. Fourth, the study of autoantonym is meaningful for dictionary compilation, language education, and clarifying the way of human conceptualization.

The herb of Hedyotis diffusa Willd (H. diffusaWilld), an annual herb distributed in northeastern Asia, hasbeen known as a traditional orientalmedicine for the treatmentof cancer. Recently, Chinese researchers have discovered thattwo anthraquinones isolated from a water extract of H. diffusaWilld showed apoptosis-inducing effects against cancer cells. However, the cellular and molecular mechanisms responsiblefor this phenomenon are poorly understood. The current studydetermines the role of mitogen-activated protein kinases(MAPK) in human leukemic U937 cells apoptosis inducedby 2-hydroxy-3-methylanthraquinone from H. diffusa. Ourresults showed that 2-hydroxy-3-methylanthraquinone decreasedphosphorylation-ERK1/2 (p-ERK1/2), and increasedp-p38MAPK, but did not affect expressions of p-JNK1/2 inU937 cells. Moreover, treatment of U937 cells with2-hydroxy-3-methylanthraquinone resulted in activation ofcaspase-3. Furthermore, PD98059 (ERK1/2 inhibitor)significantly enhanced 2-hydroxy-3-methylanthraquinoneinducedapoptosis in U937 cells, whereas caspase-3 inhibitoror SB203580 (p-p38MAPK inhibitor), decreased apoptosis inU937 cells. Taken together, our study for the first time suggeststhat 2-hydroxy-3-methylanthraquinone is able toenhance apoptosis of U937 cells, at least in part, throughactivation of p-p38MAPK and downregulation of p-ERK1/2. Moreover, the triggering of caspase-3 activation mediatedapoptotic induction.

Nan Zhang,Panghui Huang,Ping Wang,Yuanyuan Yu,Man Zhou,Qiang Wang 한국섬유공학회 2022 Fibers and polymers Vol.23 No.4

The overlapping cuticle scales on the wool surface cause severe felting shrinkage during laundering. However, theconventional wool anti-felting processing mostly adopts dichloroisocyanurate (DCCA), which produces absorbable organichalogen (AOX) with high toxicity in the effluents and cause severe environmental problems. Herein, an environmentalfriendlyenzymatic method was proposed and investigated to endow satisfactory shrink-proofing property for wool fabricswithout severe damages. The cutinase from Thermobifida fusca and the keratinolytic enzyme from Bacillus subtilis wereconsecutively used to treat wool fabrics for 4 h and 24 h, respectively. The area shrinkage of the resultant wool fabricsdecreased from 12.4 % to 5.86 % for to the cuticle was partly broken, which met the machine-washable requirement with anacceptable strength loss of 7.46 %. Moreover, the dyeability and wettability of the resultant fabric were improved after thecombined enzymatic treatments, due to the destruction of the lipid layer and breakdown of keratin by combined cutinase andkeratinolytic enzyme according to the analyses such as scanning electron microscope (SEM) and X-ray photoelectronspectroscopy (XPS) and contact angle. Overall, our result revealed that the synergistic actions of cutinase and keratinolyticenzyme treatments could effectively disintegrate cuticles and remove scales.

Influence of Preparation Conditions on the Formation of Copper (II) Architectures with Pyrazine-2,3,5-tricarboxylic Acid

Wang, Feng-Qin,Lin, Shu,Guo, Ming-Lin,Xu, Jun-Jian,Wang, Xiao-Qing,Zhao, Yong-Nan Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.7

Three new metal-organic copper(II) complexes, $[Cu(H_2PZTC)_2]_n{\cdot}2nH_2O$ (1), $[Cu(HPZTC){\cdot}2H_2O]_n{\cdot}2nH_2O$ (2), and $Cu_2[(PZHD)(OH)(H_2O)_2]_n$ (3) ($H_3PZTC$ = pyrazine-2,3,5-tricarboxylic acid, $PZHD^{3-}$ = 2-hydroxypyrazine-3,5-dicarboxylate), have been synthesized from $Cu(II)/H_3PZTC$ system under different synthetic conditions, and characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy and thermogravimetric analysis. In complexes 1 and 2, $H_3PZTC$ ligands loose one and two protons, which were transformed into $H_2PZTC^-$ anion and $HPZTC^{2-}$ dianion under different preparation condition, respectively. Furthermore, two ligands coordinate with Cu(II) cations in different modes, leading to the formation of the different chain structures. In complex 3, $H_3PZTC$ ligand was converted into a new ligand-PZHD by in situ decarboxylation and hydroxylation under a higher pH value than that for complexes 1 and 2. PZHD ligands link the Cu(II) cations to form a 2D layer structure. These results demonstrate that the preparation conditions, including pH value and reaction temperature etc, play an important role in the construction of complexes based on $H_3PZTC$ ligand.

Mitochondria-mediated Apoptosis in Human Lung Cancer A549 Cells by 4-Methylsulfinyl-3-butenyl Isothiocyanate from Radish Seeds

Wang, Nan,Wang, Wei,Huo, Po,Liu, Cai-Qin,Jin, Jian-Chang,Shen, Lian-Qing Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.5

4-Methylsulfinyl-3-butenyl isothiocyanate (MTBITC) found in the radish (Raphanus sativus L.), is a wellknown anticancer agent. In this study, the mechanisms of the MTBITC induction of cell apoptosis in human A549 lung cancer cells were investigated. Our PI staining results showed that MTBITC treatment significantly increased the apoptotic sub-G1 fraction in a dose-dependent manner. The mechanism of apoptosis induced by MTBITC was investigated by testing the change of mitochondrial membrane potential (${\Delta}{\Psi}m$), the expression of mRNAs of apoptosis-related genes by RT-PCR, and the activities of caspase-3 and -9 by caspase colorimetric assay. MTBITC treatment decreased mitochondrial membrane potential by down-regulating the rate of Bcl-2/Bax and Bcl-xL/Bax, and activation of caspase-3 and -9. Therefore, mitochondrial pathway and Bcl-2 gene family could be involved in the mechanisms of A549 cell apoptosis induced by MTBITC.

Wang, Nan,Lee, Dong-Young,Li, Xiang-Yu 한국상업교육학회 2019 상업교육연구 Vol.33 No.5

중국정부는 인구수를 기반으로 한 새로운 도시화라는 개념을 제안하고 있다, 새로 운 도시화를 촉진하려면 많은 자금지원이 필요하기 때문에 금융 지원은 새로운 도시 화를 위한 중요한 자금원이다. 본 연구는 인구와 소득 요인을 고려하여 도시화에 대 한 재무 상관비율과 재무 효율성 영향을 분석하였다. 이를 위해, 2006년부터 2015년까 지 하북성 11 개 도시의 데이터를 대상으로 회귀모형을 구축하였다. 분석결과를 보면 재무 상관비율은 인구도시화수준과 유의한 양의 상관관계를 갖고 있어 인구도시화 수준을 향상시키는데 도움이 된다. 재무 효율성과 인구도시화 사이 에는 유의한 상관관계가 나타나지 않아 재무 효율성이 인구 도시화에 영향을 미치지 못한 것을 볼 수 있다. 재무 상관비율 및 재무 효율성은 소득도시화와 유의하지 않은 상관관계가 나타나기 때문에 재무 지원이 소득도시화의 수준을 높이는데 효과적이지 못하다는 것을 보여준다. 이를 바탕으로, 본 연구는 관련정책을 제안하며 하북성의 새 로운 도시화건설 및 재무 조정개발을 위한 의사결정의 근거를 제공한다. The Chinese government puts forward the people-oriented concept of new urbanization on the basis of urbanization. The promotion of new urbanization requires a large amount of financial support, and financial support is an important source of funds for the new urbanization process. Based on the availability of data, this paper selects the panel data of 11 cities in Hebei Province from 2006 to 2015 and analyzes the influences of financial interrelations ratio and financial efficiency on population urbanization rate and income urbanization rate respectively by constructing a regression model. The analysis results show that the financial interrelations ratio has a significant positive correlation with population urbanization rate, which is conducive to improving the level of population urbanization rate. There is no significant correlation between financial efficiency and population urbanization rate, indicating that this factor has little effect on population urbanization rate. Financial interrelations ratio and financial efficiency show no significant correlation with income urbanization rate, indicating that the impact of financial support on raising the level of income urbanization is not obvious. According to the analysis results, this paper puts forward relevant recommendation to provide decision-making basis for the new urbanization construction and financial development in Hebei province.
