鄭暎錫,李龍鉉,程伊基 한국해양대학교 사회과학연구소 2000 韓國海洋大學校 人文社會科學論叢 Vol.12 No.1

Maritime lien means a statutory security right with a priority to any other right to vessel and its adjuncts which admits a person having a specific maritime claim to be paid before any other creditors. maritime lien with a priority nat having a public notice may damage to the other creditors. And the ship's arrest for the enforcement of maritime lien may atop the ship's operation. So adjustment of the interest between the person concerned is requested. Maritime lien's recognition was found in the theory of procedural, personification, Conflict, and now in the special circumstances of the maritime corp., limitation of the ship owner's liability, public policy, causam pignoris facere etc. I will suggest some proposals to improve this subject in this paper.

K-doping effect of the superconductivity in K2xFeTe1-xSx (0.07 ≤ x ≤ 0.3)

Cheng Cheng,Zhenjie Feng,Qing Li,Tao Li,Qiang Hou,Fei Chen,Zhongmin Ou,Jun-Yi Ge,Shixun Cao,Jincang Zhang 한국물리학회 2019 Current Applied Physics Vol.19 No.4

Bulk samples of K doping K2xFeTe1-xSx with x=0.07, 0.1, 0.2, 0.3 are successfully prepared by using easy-to-use stable compound K2S as the reactant. The lattice constant calculated from X-ray diffraction patterns indicate that K ions enter the Fe-Te-S layers. K doping is beneficial enhance the superconductivity transition temperature from the R-T curves. The apparent diamagnetic signal is observed in M-T curves when the content of K is smaller than 0.1. However, differential curves (dM/dT) in K-rich samples appear sharp slope mutations, which means that the Meissner effect signal is covered by the increased excess ferromagnetic ions. The number of excess Fe magnetic ions is proportional to K content, which may play an important role in determining the superconductivity.

Antitumor Activity of Histone Deacetylase Inhibitor Trichostatin A in Osteosarcoma Cells

Cheng, Dong-Dong,Yang, Qing-Cheng,Zhang, Zhi-Chang,Yang, Cui-Xia,Liu, Yi-Wen Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.4

Background: Histone deacetylase (HDAC) inhibitors have been reported to induce cell growth arrest, apoptosis and differentiation of tumor cells. The present study aimed to examine the effects of trichostatin A (TSA), one such inhibitor, on the cell cycle, apoptosis and invasiveness of osteosarcoma cells. Methods: MG-63 cells were treated with TSA at various concentrations. Then, cell growth and apoptosis were determined by 3-(4, 5-dimethyl-2-thiazolyl)-2H-tetrazolium bromide (MTT) and TUNEL assays, respectively; cell cycling was assessed by flow cytometry; invasion assays were performed with the transwell Boyden Chamber system. Results: MTT assays revealed that TSA significantly inhibited the growth of MG-63 cells in a concentration and time dependent manner. TSA treated cells demonstrated morphological changes indicative of apoptosis and TUNEL assays revealed increased apoptosis of MG-63 cells after TSA treatment. Flow cytometry showed that TSA arrested the cell cycle in G1/G2 phase and annexin V positive apoptotic cells increased markedly. In addition, the invasiveness of MG-63 cells was inhibited by TSA in a concentration dependent manner. Conclusion: Our findings demonstrate that TSA inhibits the proliferation, induces apoptosis and inhibits invasiveness of osteosarcoma cells in vitro. HDAC inhibitors may thus have promise to become new therapeutic agents against osteosarcoma.

Risks of cervical intraepithelial neoplasia grade 3 or invasive cancers in ASCUS women with different management: a population-based cohort study

Yi-Jou Tai,Yun-Yuan Chen,Huang-Cheng Hsu,Chun-Ju Chiang,San-Lin You,Chi-An Chen,Wen-Fang Cheng,Taiwan Cervical Cancer Control Task Force 대한부인종양학회 2018 Journal of Gynecologic Oncology Vol.29 No.4

OBJECTIVE: To investigate the progression risk of atypical squamous cells of undetermined significance (ASCUS) with different clinical managements. METHODS: Women with their first diagnosis of ASCUS cytology were retrieved from the national cervical cancer screening database and linked to the national health insurance research database to identify the management of these women. The incidences of developing cervical intraepithelial neoplasia grade 3 and invasive cervical cancer (CIN3+) were calculated, and the hazard ratios (HRs) were estimated using a Cox proportional hazards model. This study was approved by the Research Ethics Committee of the National Taiwan University Hospital and is registered at ClinicalTrials.gov (Identifier: NCT02063152). RESULTS: There were total 69,741 women included. Various management strategies including colposcopy, cervical biopsies and/or endocervical curettage, and cryotherapy, failed to reduce the risk of subsequent CIN3+ compared with repeat cervical smears. Loop electrosurgical excision procedure/conization significantly decreased risk of subsequent CIN3+ lesions (HR=0.22; 95% confidence interval [CI]=0.07–0.68; p=0.010). Women in their 40s–50s had an approximately 30% risk reduction compared to other age groups. Women with a previous screening history >5 years from the present ASCUS diagnosis were at increased risk for CIN3+ (HR=1.24; 95% CI=1.03–1.49; p=0.020). CONCLUSION: In women of first-time ASCUS cytology, a program of repeat cytology can be an acceptable clinical option in low-resource settings. Caution should be taken especially in women with remote cervical screening history more than 5 years.

Rapidly Self-Assembling Three-Dimensional Opal Photonic Crystals

Cheng Yi Wu,Ngoc Diep Lai,Chia Chen Hsu 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.52 No.5

We demonstrate a useful technique to rapidly self-assemble silica particles to form opal photonic crystals. Silica suspensions were first synthesized following the single-step Stober's method, with controllable particles diameters ranging from 200 to 800 nm. The suspensions were then injected into a cubic cell composed of two glass substrates and two controllable spacers. The self-assembly process was accelerated by heating the cell to an arbitrary temperature between 30℃ and 90℃. The opal particles were self-assembled into ordered structures within several minutes. The periodic structures were characterized by checking the scanning electron microscopy images and measuring the re ection spectra. The structure was quite uniform for very large areas and the number of layers could be controlled by using the formation temperature. The measured re ection spectra were in agreement with the simulation results obtained by using the transfer matrix method. The re ection spectra were blue shifted as the incident angle deviated from the normal direction, which could be justified simply by using a combination of Bragg formula and Snell's Law.

Advances of Hospice Palliative Care in Taiwan

Cheng, Shao-Yi,Chen, Ching-Yu,Chiu, Tai-Yuan Korean Society for Hospice and Palliative Care 2016 한국호스피스.완화의료학회지 Vol.19 No.4

목적: 대만의 호스피스와 완화 의료는 지속적으로 증가하고 있다. Economist Intelligence Unit에서 평가한 2015년 죽음의 질 지수 등급에서 대만은 아시아 국가 중에서 1위, 세계에서 6위를 기록했다. 이 리뷰 기사에서 우리는 성공에 기여한 것으로 보이는 세 영역, 즉 법률 및 규정, 영적 치료, 연구 네트워크에 주목하였다. 마지막으로 대만 사람에게 적용을 위한 미래의 도전과 전망에 대해 논의하기로 한다. 방법: PubMed에서 "대만의 호스피스 완화의료" 검색어를 이용해 체계적인 검토를 수행하였다. 결과: 2000년에 "자연사법"의 통과로 아시아에서 환자의 자기결정권에 대한 획기적인 본보기가 만들어지고 확립되었다. 이는 의료진에게 연명치료중지(DNR, do not resuscitate)를 요청할 수 있고 삶의 마지막에 기타 무의미한 의료 행위를 거부할 수 있는 환자의 권리를 보장하며 더불어 정책적 관점에서 완화의료의 중요성을 반영하는 것이다. 2015년에 대만은 "환자의 자기결정권 특별법"이라는 선구적인 법률을 통과시켰다. 이 법은 환자가 그/그녀의 자기의지에 따라 의료 행위를 거부할 수 있다는 것을 규정한다. 대만 고유의 영적 치료는 2000년에 도입되었는데, 불교 수행을 죽음에 직면한 환자에 적용하기 이전의 임상실습뿐 아니라 강의들로 구성된 훈련 프로그램을 성공적으로 이수하기 위해서는 불교 사제가 필요하다. 일본-한국-대만 연구 네트워크는 죽음의 과정을 자세히 설명(EASED, Elucidate the Dying process)하기 위한 동아시아 공동의 비교 문화 집단 연구를 위해 설립되었다. 결론: 대만에서의 호스피스와 완화의료는 정부와 사회의 우선적 합의에 따라 꾸준하게 성장하고 있다. Hospice and palliative care in Taiwan has been growing continuously. The 2015 Quality of Death index, as rated by the Economist Intelligence Unit, ranked Taiwan first among Asian countries and sixth in the world. In this review article, we highlight three particular areas that might have contributed to this success; the laws and regulations, spiritual care and research network. Finally, we discuss the future challenges and prospects for Taiwanese encounters. A systemic review was conducted with the keywords "hospice palliative care Taiwan" using PubMed. The passing of the "Natural Death Act" in 2000 set the example and established a landmark for patient autonomy in Asia; it guarantees the patient's right to request that medical staff do not resuscitate (DNR) them and to reject other futile medical treatments at the end of their life, thus reflecting the importance of palliative care from the policy perspective. In 2015, Taiwan passed another pioneering law entitled the "Patient Autonomy Act". This law states that a patient may decline medical treatment according to his/her own will. Taiwanese indigenous spiritual care was launched in 2000. It requires a Buddhist Chaplain to successfully complete a training program consisting of lectures, as well as bedside practicum before applying Buddhist practices to end-of-life care. The Japan-Korea-Taiwan research network was established for the purpose of enabling collaborative research for the East-Asian collaborative cross-cultural Study to Elucidate the Dying process (EASED) cohort. With consensus from the government and society to make it a priority, hospice and palliative medicine in Taiwan has been growing steadily.

Analysis of genetic diversity and population structure of rice cultivars from Africa, Asia, Europe, South America, and Oceania using SSR markers

Cheng, Yi,Cho, Young-Il,Chung, Jong-Wook,Ma, Kyung-Ho,Park, Yong-Jin The Korean Society of Crop Science 2009 Korean journal of crop science Vol.54 No.4

In this study, 29 simple sequence repeat (SSR) markers were used to analyze the genetic diversity and population structure of 125 rice accessions from 40 different origins in Africa, Asia, Europe, South America, and Oceania. A total of 333 alleles were detected, with an average of 11.5 per locus. The mean values of major allele frequency, expected heterozygosity, and polymorphism information content (PIC) for each SSR locus were 0.39, 0.73, and 0.70, respectively. The highest mean PIC was 0.71 for Asia, followed by 0.66 for Africa, 0.59 for South America, 0.53 for Europe, and 0.47 for Oceania. Model-based structure analysis revealed the presence of five subpopulations, which was basically consistent with clustering based on genetic distance. Some accessions were clearly assigned to a single population in which >70% of their inferred ancestry was derived from one of the model-based populations. In addition, 12 accessions (9.6%) were categorized as having admixed ancestry. The results could be used to understanding the genetic structure of rice cultivars from these regions and to support effective breeding programs to broaden the genetic basis of rice varieties.

Pepsin and Laryngeal and Hypopharyngeal Carcinomas

Cheng-Yi Yin,Sha-Sha Zhang,Jiang-Tao Zhong,Shui-Hong Zhou 대한이비인후과학회 2021 Clinical and Experimental Otorhinolaryngology Vol.14 No.2

Laryngeal and hypopharyngeal carcinomas are common malignant tumors of the head and neck, and the incidence of both is increasing. Laryngopharyngeal reflux refers to the retrograde flow of gastric contents into the larynx, oropharynx, and/or nasopharynx. It remains controversial whether laryngopharyngeal reflux is a risk factor for laryngeal and hypopharyngeal cancers. The refluxing substances mainly include hydrochloric acid, pepsin, and occasionally bile acids and bile salts, as well as bacteria that colonize the gastrointestinal tract. Loss of epithelium in the mucous membrane of the larynx and hypopharynx is thought to be caused by pepsin. Here, we review the relationships between laryngopharyngeal reflux and both laryngeal and hypopharyngeal carcinomas, as well as the significance of pepsin, methods of clinical detection, and the mechanism of carcinogenesis.
