Optimal Trade and Privatization Policies in an International Mixed Market

Rong Yu,Sang-Ho Lee 서울대학교 경제연구소 2011 Seoul journal of economics Vol.24 No.1

This paper examines the optimal trade and privatization policies in an international mixed market where a domestic public firm competes against domestic and foreign private firms. We consider a trade policy combination of production subsidy and import tariff, and compare the optimal trade and privatization policies under either Cournot or Stackelberg competition. We find that the optimal trade policies consist of a domestic production subsidy and an import tariff, which are identical under the two regimes regardless of the competition pattern. However, the optimal privatization policy depends on the competition patterns, whether Cournot or Stackelberg competition. In particular, the optimal privatization policy under Cournot competition is complete privatization, whereas that under Stackelberg competition is full nationalization. Finally, we show that if the government can only use a single trade policy instrument, the production subsidy gives a better social welfare benefit than the import tariff.

Tyrosinase inhibitors are clinically effective for treating some dermatological disorders related to melanin hyperpigmentation. Accordingly, the discovery and development of tyrosinase inhibitors have great value in the pharmaceutical and cosmetic industry. Here, a novel tyrosinase inhibitor, 6′-O-cinnamoyl-helicid (helicid cinnamylate) was successfully synthesized by a simple and effective biocatalytic approach with Aspergillus oryzae cells. Investigation of the effects of several key variables on helicid cinnamylate synthesis found that the reaction conversion, reaction rate and regioselectivity reached 99%, 9.40 mM/h and > 99%, respectively, at the optimal conditions with anhydrous acetone as the solvent, whole-cell concentration of 40 mg/mL, and the molar ratio of vinyl cinnamate to helicid of 10 at 45°C. The whole-cells retained 68.87% of its initial activity after reusing for seven batches, indicating a potent application potential in non-aqueous biocatalytic systems. It was worth noting that helicid cinnamylate demonstrated a more potent tyrosinase inhibitory activity with an IC50 value of 3.55 mM than helicid (IC50 = 4.48 mM) and arbutin (IC50 = 5.48 mM), which suggest that helicid cinnamylate could be developed as a more potential tyrosinase inhibitor. In conclusion, this study provides a novel whole-cell catalytic approach for the synthesis of helicid cinnamylate and insight into its application as a tyrosinase inhibitor.

Zhang, Yu-Rong,Xu, Yong,Yang, Kuo,Liu, Ming,Wei, Dong,Zhang, Yao-Guang,Shi, Xiao-Hong,Wang, Jian-Ye,Yang, Fan,Wang, Xin,Liang, Si-Ying,Zhao, Cheng-Xiao,Wang, Fei,Chen, Xin,Sun, Liang,Zhu, Xiao-Quan,Zh Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.12

Background/Aim: Six prostate cancer (PCa) susceptibility loci were identified in a genome-wide association study (GWAS) in populations of European decent. However, the associations of these 6 single-nucleotide polymorphisms (SNPs) with PCa has remained tobe clarified in men in Northern China. This study aimed to explore the loci associated with PCa risk in a Northern Chinese population. Methods: Blood samples and clinical information of 289 PCa patients and 288 controls from Beijing and Tianjin were collected. All risk SNPs were genotyped using polymerase chain reaction (PCR)-high resolution melting curve technology and gene sequencing. Associations between PCa and clinical covariates (age at diagnosis, prostate-specific antigen [PSA], Gleason score, tumor stage, and level of aggressiveness) and frequencies of alleles and genotypes of these SNPs were analyzed using genetic statistics. Results: Among the candidate SNPs, 11p15 (rs7127900, A) was associated with PCa risk (P = 0.02, odds ratio [OR] = 1.64, 95% confidence interval [CI] = 1.09-2.46). Genotypes showed differences between cases and controls on 11p15 (rs7127900, A), 11q13 (rs7931342, T), and HNF1B (rs4430796, A) (P = 0.03, P = 0.01, and P = 0.04, respectively). The genotype TG on 11q13 (rs7931342, T) was positively associated with an increased Gleason score (P = 0.04, OR = 2.15, 95% CI = 1.02-4.55). Patients carrying TG on 17q24 (rs1859962, G) were negatively associated with an increased body mass index (BMI) (P = 0.03, OR = 0.44, 95% CI = 0.21-0.92) while those with AG on HNF1B (rs4430796, A) were more likely to have PSA increase (P = 0.002). Conclusion: Our study suggests that 11p15 (rs7127900, A) could be a susceptibility locus associated with PCa in Northern Chinese. Genotype TG on 11q13 (rs7931342, T) could be related to an increased Gleason score, AG on HNF1B (rs4430796, A) could be associated with PSA increase, and TG on 17q24 (rs1859962, G) could be negatively associated with an increased BMI in Chinese men with PCa.

Jin Rong,Kim Ho Soo,Yu Tao,Liu Ming,Yu Wenhui,Zhao Peng,Zhang Aijun,Zhang Qiangqiang,Liu Yaju,Cao Qinghe,Kwak Sang-Soo,Tang Zhonghou 한국식물생명공학회 2022 Plant biotechnology reports Vol.16 No.1

Sweetpotato is an important crop that is very sensitive to low temperatures. Mitogen-activated protein kinase (MAPK) is involved in plant growth and development and is responsive to many environmental stresses. IbMPK3 is strongly regulated by low-temperature stress. We studied the function of IbMPK3 and how it may enhance the adaptability of sweetpotato plants to low-temperature stress. Transgenic sweetpotato plants overexpressing IbMPK3 were generated, and three trans- genic lines with the highest expression level of IbMPK3 were used for low-temperature tests. Transgenic plants exposed to low-temperature stress had less damage associated with higher photosynthesis efficiency and less cell membrane damage. IbMPK3-overexpressing transgenic plants could modulate reactive oxygen species (ROS) metabolism with lower levels of O2− and H2O2 accumulation and higher enzymatic activities than WT plants. Transcript expression levels of some ROS- related genes (IbCAT, IbCu-ZnSOD, and IbCAT) and stress-responsive genes (IbP3B and IbCOR27) were significantly upregulated in transgenic plants compared to WT. These results indicate that IbMPK3 has an important role in sweetpotato response to low temperatures.

육우용 ( Yu Rong Lu ),조성균 ( Sung Kyun Cho ),전익기 ( Jeon Ik Ki ) 한국체육사학회 2014 체육사학회지 Vol.19 No.4

본 연구에서는 중국 근대 시기에 학교체육으로서 중국무술의 도입과 발전과정을 구체적으로 고찰한 후 중국무술의 전개과정 중에 내재되어 있는 의미를 밝히는데 연구목적이 있다. 이러한 연구목적에 따라 다음과 같은 결론을 도출하였다. 첫째, 근대 시기에 서양체육은 다른 학문영역과 같이 외국인들에 의해 유입되거나, 중국인들의 자발적 의사에 의해 도입된 두 가지 유입 형태가 있었다. 1903년에 청(淸) 정부가 공포한 《주정학당장정(奏定學堂章程)》에 처음으로 무술이 학교의 필수과목으로 확정되었다. 둘째, 1915년에 무술은 체육인들과 체육단체의 노력에 의해 학교체육 정식 교과목으로 채택되었다. 셋째, 근대시기에 일어난 서양체육과 중국의 전통체육에 대한 논쟁으로 서양체육과 무술과의 융합의 계기가 되었으며, 무술이 학교체육 교과과정으로 채택되는데 주요한 과정이기도 하였다. 무술교사 양성 측면에서 살펴보면, 무술교사의 부족한 실정에 따라서 사범학교와 체육학교에서 무술교사가 양성되기 시작하였으며, 그들이 근대 시기에 무술을 보급하는데 큰 역할을 하였다. 또한 사회 각계각층의 인사들의 무술 교육 필요성에 대한 강조는 근대시기에 무술이 학교체육 교과과정에 도입되는 계기가 되었다. The purpose of this study was to investigate the process of introducing Chinese martial arts to school physical education in modern times of China and understand its meaning in its development in precise. The results are as follows according to such purposes. Firstly, physical education of the West was flowed in two ways; entered with the Western theories in modern times or introduced by the willful intention of Chinese. It was first determined as a regular curriculum by 《Presented School Regulation(奏定學堂章程)》 announced by Qing government in 1903. Secondly, martial arts was adopted as a regular academic course by the efforts of physicians and physical organizations in 1915. Thirdly, discussion about the Western sports and Chinese traditional ones that initiated in modern times ended to form a fusion course of the Western physical education and martial arts, which became an important process for martial arts to be adopted as an academic curriculum. Seen from the perspective of nurturing martial arts teachers, education and physics schools were short of martial arts teacher so they began nurturing them. Those teachers did a big role in spreading martial arts in modern times. In addition to that, people from all fields put emphasis on education of martial arts, which gained momentum for it to be introduced to the school curriculum in modern times.

중국 근대 민간무술단체에 관한 고찰 -중화무사회(中華武士會)의 설립, 활동 및 인물을 중심으로-

육우용 ( Yu Rong Lu ),박태승 ( Tae Seung Park ),전익기 ( Ik Ki Jeon ) 한국체육사학회 2014 체육사학회지 Vol.19 No.3

본 연구는 중국 근대시기에 민간무술단체 중 대표적인 중화무사회의 설립, 활동 그리고 주요인물을 중심으로 고찰한 후 민간무술단체가 근대 중국무술 발전과정에 어떠한 역할을 하였는지 탐색하는데 목적을 두었다. 중화무사회는 1911년 신해혁명 이후 “상무강국(尙武强國)”이라는 민족주의 체육사상이 대두되었던 시대배경 하에 1912년 6월 16일 민주혁명단체인 동맹회(同盟會)와 정부의 지지를 받은 이존의(李存義)를 비롯한 무술가들에 의해 천진에 설립되었다. 1912년부터 중화무사회는 중국무술을 보급하기 위하여 각종 무술시범대회를 열었고, 국내·외 많은 분회를 설립하여 무술을 전파하는 활동을 하였으나, 1928년 그 당시 시대의 흐름에 따라 16년을 거쳐서 중화무사회는 해체되었다. 그 당시 중화무사회의 주요창시자들인 이존의(李存義), 이서동(李瑞東), 장점괴(張占魁)와 제3대 회장인 이성계(李星階)는 중국 근대시기의 무술명가로서 중화무사회의 발전 및 근대 중국무술의 보급과 전파에 기여를 하였다. The purpose of this study is to explore the role of folk martial arts group in modern development of Chinese Martial Arts. It was based on the investigation of settle up, activities and key figures of Chinese Warrior Society. With the supports of democratic revolutionary groups-Chinese Revolutionary League and the government, Chinese Warrior Society established on 16th of June 1912 under the background of rising nationalist sports ideology of “the spirit of martial art is the origin of powerful country” in Tianjin after the Revolution in 1911 by martial artists headed by Li Cunyi. Since 1912, Chinese Warrior Society organized a variety of martial arts assembly and opened many branches for spreading martial arts both domestically and abroad to popularize Chinese martial arts. However, in 1928, Chinese Warrior Society eventually disintegrated after 16 years due to the current events. Li Cunyi, Li Ruidong, Zhang Zhankui, the main founders and Li Xingjie, the third generation president contributed to the development of Chinese Warrior Society and the widespread of modern Chinese martial arts.
