Peng,Lin Feng,Chung Yi Tsai,Zuei Ching Chen 한국산림과학회 1985 한국산림과학회지 Vol.71 No.1

In 1966, the outbreak of a rust disease was discovered from the young plantation of Taiwan red pine (Pines taiwanensis Hay.) at the northeastern part of Taiwan Island. The plantation of about 2,000㏊ planted with 3-4 years old saplings is located on the mountain slopes of a valley of the upper stream of Ta-Chia River. The rust disease was first discovered sporadically from the narrow margin of plantation surrounding the pine nursery which was located at the center of valley. The disease spread rapidly and the total infected area in 1968 had been recorded for 186 ha. The rust fungus was first identified as Cronartium ribicola J.C. Fischer. The alternative hosts of this rust fungus, Ribes spp. were not recovered from the area of infectian sites nor from the area of 20Km radius from the infected site. Instead of Ribes host, Paeonia suffruticosa Andr. were planted in the nursery near by the pine nursery from 1966. It was thus identified the rust fungus as Cronartium flaccidum (Alb. et Schw.) Wint. The extensive control measures were practiced from 1968 and the eradication of infected saplings, shrubs and weeds of forest floors was given the first priority. In total, 111,852 trees infected were felled down from 1966 to 1971. All infected branches or parts of the trees were first wrapped with the vinyl film to prevent the dispersion of rust spores and then trees were felled down and finally were burnt at the site. Rest of pine trees of the whole plantation were sprayed with the fungicides; 0.2% Dithane Z-78 or 4-4 Bordeux mixture with addition of 1% Uspulun. Spraying of fungicides was carried out at least twice a month and continued to 1971. In 1973 and 1974, reforestation by some resistance tree species such as Pines armandi Fr., Taiwania, Cryptomeria, or Chamaecyparis, etc, were practiced. In total, 148,500 seedlings of tree species mentioned above were replaced the infected pine trees. Since the first outbreak of the disease in 1966, 20 years have been passed without any new outbreak of the rust disease by C. flaccidum in the same site or any other plantations in Taiwan. The control of the rust disease erupted in Taiwan red pine plantation in 1966 in thus concluded as very successful.

As per the 2018 GLOBOCAN database, Asia accounted for 48.7% (637,761) of new gynecologiccancer cases and 50.1% (305,000) of gynecologic cancer deaths [1]. Recognizing the distinctdifferences in genetic background, cancer epidemiology, disease characteristics, and socio-cultural environment between Asian and non-Asian women, it is noteworthy that much ofthe experimental evidence guiding clinical gynecologic oncology practices has historicallybeen drawn from studies in Western populations. Established in 2008, the Asian Society ofGynecologic Oncology (ASGO) ser ves as a key organization in Asia, dedicated to advancingthe study, prevention, and treatment of gynecological cancer through scientific exchange,regional/international collaboration, educational initiatives, and fostering camaraderieamong its members [2]. Presently, ASGO boasts members from over 10 countries in Asia. Building on the success of the previous meetings held in Tokyo (2009) [3], Seoul (2011)[4], Kyoto (2013) [5], Seoul (2015) [6], Tokyo (2017) [7], Incheon (2019) [8], and Bangkok(2021) [9], the eighth Biennial Meeting of ASGO took place at the state-of-the-art HNBKInternational Convention Center in Taipei, Taiwan, from December 01 to 03, 2023. Theoverarching theme for this event was “Reunion to Overcome Gynecologic Cancer in Asia.”Notably, due to the impact of the coronavirus disease 2019 pandemic in 2021, the meetingwas transformed into a hybrid format. This gathering marked a significant milestone as thefirst in-person Pan-Asia meeting focused on gynecological cancer following the pandemic. Additionally, it is worth highlighting that this was the inaugural ASGO meeting held outsideof Korea and Japan, underscoring the broadening geographical scope and global impactof the conference. Professor Peng-Hui Wang and Jae-Weon Jim chaired the organizingcommittee. ASGO 2023 witnessed the participation of 633 attendees from 17 countries,featuring 152 honored speakers and chairs from 12 countries. The event included 44 oral/surgical video presentations and 187 poster presentations, covering a diverse range ofscientific topics, from fundamental principles of gynecological cancer care to advanced, high-technology practices rooted in cutting-edge research (Table 1).

Objective In this research, the influence of breviscapine on anxiety, fear elimination, and aggression and the potential mechanism was investigated. Methods Anxiety and locomotion were analyzed by elevated plus maze and open field test in mice. Bussey-Saksida Mouse Touch Screen Chambers were used to perform fear conditioning. Territorial aggression was assessed by resident intruder test. Protein levels were evaluated by Western blot. Breviscapine improved fear-extinction learning in BALB/cJ mice. Results Breviscapine at 20-100 mg/kg increased center cross number, total distance traveled, and velocity in a dose-dependent manner. On the other hand, breviscapine at 20-100 mg/kg decreased the immobility time in open field test. In addition, breviscapine at 20-100 mg/kg increased the ratio of time on the open arm, time on the distal parts of the open arm, and total distance traveled in elevated plus maze. Breviscapine at 100 mg/kg increased the average attack latency and decreased the number of attacks over the last 3 days of resident intruder test. In hippocampus, protein levels of postsynaptic density protein-95 and synaptophysin were elevated by breviscapine at these three doses. Conclusion The administration of breviscapine alleviates fear extinction, anxiety, and aggression, while increases locomotor in a dose-dependent manner, which might be associated with its influence on synaptic function.

Purpose: Some evidence suggests that male infertility increases the risk of cardiovascular diseases (CVDs). However, the evidence in Asian populations is relatively scarce. The aim of this study is to determine whether male infertility increases the risk of CVDs. Materials and Methods: We used inpatient and outpatient data for the years 2000 to 2015 from the Taiwanese Longitudinal Health Insurance Database. We enrolled 7,016 males over 18 years old and diagnosed with male infertility. Of these, 2,326 matched our inclusion criteria and were assigned to the study group. For each infertility patient, four comparison patients were frequency-matched by age and index date to form a control cohort comprising 9,304 patients. Cox proportional hazards analysis was used to estimate the association between male infertility and CVDs. Results: After a 15-year follow-up, the incidence rate of CVDs was higher in the infertility group than the control group (1,460.23 and 1,073.70 per 100,000 person-years, respectively). The Cox proportional hazards regression analysis revealed that the adjusted HR for CVDs was 1.472 for the infertility group (95% CI, 1.288–1.683; p<0.001) relative to the control group. The Kaplan–Meier analysis of the cumulative incidence of CVDs in the two groups showed that the cumulative risk curve for CVDs was significantly higher for the infertility group than the control group. Conclusions: This study shows that men with infertility have a higher risk of developing incident CVDs. In the future, healthcare providers should pay attention to these patients because of their higher health risks.

AtHAP3b Plays a Crucial Role in the Regulation of Flowering Time in Arabidopsis during Osmotic Stress

Chen, Nai-Zhi,Zhang, Xiu-Qing,Wei, Peng-Cheng,Chen, Qi-Jun,Ren, Fei,Chen, Jia,Wang, Xue-Chen Korean Society for Biochemistry and Molecular Biol 2007 Journal of biochemistry and molecular biology Vol.40 No.6

The HAP complex has been found in many eukaryotic organisms. HAP recognizes the CCAAT box present in the promoters of 30% of all eukaryotic genes. The HAP complex consists of three subunits - HAP2, HAP3 and HAP5. In this paper, we report the biological function of the AtHAP3b gene that encodes one of the HAP3 subunits in Arabidopsis. Compared with wild-type plants, hap3b-1 and hap3b-2 mutants exhibited a delayed flowering time under long-day photoperiod conditions. Moreover, the transcription levels of FT were substantially lower in the mutants than in the wild-type plants. These results imply that AtHAP3b may function in the control of flowering time by regulating the expression of FT in Arabidopsis. In a subsequent study, AtHAP3b was found to be induced by osmotic stress. Under osmotic stress conditions, the hap3b- 1 and hap3b-2 mutants flowered considerably later than the wild-type plants. These results suggest that the AtHAP3b gene plays more important roles in the control of flowering under osmotic stress in Arabidopsis.

Dexmedetomidine (DEX) is an anesthetic that is widely used in the clinic, and it has been reported to exhibit paradoxical effects in the progression of multiple solid tumors. In this study, we sought to explore the mechanism by which DEX regulates hepatocellular carcinoma (HCC) progression underlying liver fibrosis. We determined the effects of DEX on tumor progression in an orthotopic HCC mouse model of fibrotic liver. A coculture system and a subcutaneous xenograft model involving coimplantation of mouse hepatoma cells (H22) and primary activated hepatic stellate cells (aHSCs) were used to study the effects of DEX on HCC progression. We found that in the preclinical mouse model of liver fibrosis, DEX treatment significantly shortened median survival time and promoted tumor growth, intrahepatic metastasis and pulmonary metastasis. The DEX receptor (ADRA2A) was mainly expressed in aHSCs but was barely detected in HCC cells. DEX dramatically reinforced HCC malignant behaviors in the presence of aHSCs in both the coculture system and the coimplantation mouse model, but DEX alone exerted no significant effects on the malignancy of HCC. Mechanistically, DEX induced IL-6 secretion from aHSCs and promoted HCC progression via STAT3 activation. Our findings provide evidence that the clinical application of DEX may cause undesirable side effects in HCC patients with liver fibrosis.

On the historicity of the development and evolution of the concept of globalization

Yang Peng(Peng Yang),Chen Ziwei(Ziwei Chen) 아시아사회과학학회 2022 Jornal of Asia Social Science Vol.8 No.1

Globalization is a world-class phenomenon, and it is the cross-border and cultural spread of factors such as the production of products, the application of technology, the dissemination of information, and jobs among different countries. Globalization is a widespread phenomenon that includes economic, political, social, cultural and legal factors. From the economic point of view, globalization explains the free trade in which different countries are interdependent through various forms. From the political point of view, the evolution of globalization is developing towards the structure of intergovernmental organizations, such as the WTO and the United Nations. From the social and cultural point of view, globalization makes the interaction and cultural exchange among ethnic groups closer. Globalization also represents the exchange and collision of cultural concepts, thoughts and artistic expressions among different regions. In addition, there is a general trend of globalization towards a single world culture. From the perspective of law, globalization has adjusted the construction and implementation of international law. In the author's opinion, globalization is not a new concept in recent decades. In ancient human society a long time ago, there were merchants who traveled long distances to another country and region, taking their hometown specialties for sale, or bringing overseas specialty products back to their hometown for sale. With the development of industrial revolution, it created a great leap in the development of transportation and communication means for human society in the 19th century, and also greatly reduced the difficulty of cross-border trade. Through a brief analysis of the historical evolution of economic globalization, political globalization and social and cultural globalization, this paper shows that globalization is the result of historical development in recent centuries, rather than a fresh product in recent decades.

중국 교사 양성과정 중의 견습교육과정(敎育見習)에 대한 만족도 조사: 중국 하남성 Z사범대학교 초등교육과 학생을 대상으로

CHEN PENG 한국지방교육경영학회 2019 지방교육경영 Vol.22 No.1

이 연구는 교사 양성과정에서 교사의 실천적 능력을 키우는 견습교육과정에 대한 견습생들의 만족도가 어떤지를 분석하였다. 이에 따라 연구자는 중국 하남성 Z사범대학교 초등 교육과 학생을 대상으로 개방형 설문조사와 집단 면담 방법을 사용하여 조사하였다. 연구 결과는 다음과 같다. 첫째, 견습생들이 견습교육과정에 대하여 만족하는 영역은 수평적 인간관계, 전문성 발전, 조건, 관리로 나눌 수 있고 만족하지 못 한 점은 전문성 발전, 조건, 관리 등의 3가지 영역이다. 둘째, 견습생들이 교직 신념 이해, 교수-학습과 학급 질서 관리에 대한 학습, 학과 교육과정에 대한 성찰 등에 만족하였고, 관리 부실, 수업 참관 거절, 준비 없는 수업 실행 등에 불만이 많았다. 이에 따라 우수 수업을 참관하는 것, 학과 교육과정에 대하여 성찰하는 것, 적당한 자유권을 부여되는 것 등을 계승하여 발전시켜야 하고 견습학교 교사의 일상 수업 참관에 거부하는 태도, 양성교육기관과 견습학교가 견습교육과정의 중요성에 대한 인식 부족, 견습학교에서 제공하는 전문적 조건이 부족하다는 문제점도 있었다. 그러므로 견습교육과정에 대한 중요성 인식, 양성기관의 효과적 관리, 견습학교의 협동적 태도 및 행동 등은 중국뿐만 아니라 한국의 예비교사 실습에도 참조될 수 있을 것이고 이 연구에서 수집된 실증자료는 양국의 예비교사의 실천 능력 향상에 도움이 될 수 있을 것이다. The purpose of this paper is to investigate the satisfaction of educational probation in the process of teacher training. Therefore, the students majoring in primary education in Z normal university in henan province, China, are taken as the research objects, and the open questionnaire survey and group interview method are implemented. The results are as follows. Firstly, there are four areas in which students are satisfied with their education probation: interpersonal relationship with primary school teachers, professional development, conditions and management. And the three areas of dissatisfaction are "professional development, conditions and management". Secondly, the students are satisfied with the understanding of teacher beliefs, the learning of teaching and discipline management, and the reflection on their education curriculum. They dissatisfied with the irresponsible management, the refusal of attending class and the unprepared class. Based on the above research results, the following points can be carried forward in educational probation. Visit quality class, think about education curriculum critically and give students appropriate autonomy. There were problems such as the teachers in the primary school refuse to listen to their class, the lack of awareness of the importance of the probation by the institution and the primary school, the primary school can not provide professional conditions. Therefore, awareness of the importance of education probation, effective management of the training institutions, cooperative attitudes and behaviors of primary schools could be referred to not only in China but also in Korea's pre-service teachers' practice, and the empirical data collected in the study could help improve the practical ability of pre-service teachers in both countries.

Patterns and Trends with Cancer Incidence and Mortality Rates Reported by the China National Cancer Registry

Chen, Peng-Lai,Zhao, Ting,Feng, Rui,Chai, Jing,Tong, Gui-Xian,Wang, De-Bin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

National cancer registration reports provide a huge potential for identifying patterns and trends of important policy, research, prevention and treatment significance. As summary reports written on an annual basis, the China Cancer Registry Annual Reports (CCRARs) fall short from fully addressing their potential. This paper attempts to explore part of the patterns and trends hidden behind published CCRARs. It extracted data for cancer incidence rates (IRs) and mortality rates (MRs) for 2004, 2006 and 2009 from relevant CCRARs and portrayed 4 kinds of indicators in line graphs. The study showed that: a) all of the line graphs of age-specific IRs and MRs characterized typical "growth curves or histogram"; b) graphs of IRs and MRs for males and urban areas had higher peaks than that for females and rural regions; c) most of the line graphs of IR/MR ratios comprised a starting peak, a secondary peak and a decreasing tail and the secondary peaks for females and urban areas were higher than those for males and rural areas; d) most of the urban versus rural IR ratios valued above one, but most the urban versus rural MR ratios, below one; e) the accumulative IRs and MRs showed a stable increasing trend from 2004 to 2009 for urban areas, but mixed for rural regions.
