Objective: This study was performed to evaluated the efficacy and safety of continuous infusional paclitaxel and 5-Fu as first-line chemotherapy in patients with advanced esophageal squamous cell cancer (ESCC). Methods: A total of 22 patients with advanced esophageal squamous cell cancer with no indications for surgery and radiation therapy, or recurrent patients were enrolled from October 2008 to November 2010. All were treated with PTX 20 $mg/m^2$ was administered through a 16 hours continuous intravenous infusion on days 1 to 3, 8 and 9. DDP 3.75 $mg/m^2$ was given on days 1 to 4 and 8 to 11, continuous infusional 5-FU over 24-hours on days 1 to 5 and 8 to 12 at a dose of 375 $mg/m^2$, and folacin 60 mg orally synchronized with 5-Fu. The treatment was repeated every 21 days for at least two cycles. Results: 22 cases of all enrolled patients could be evaluated for the effect of treatment: 2 cases were CR, 9 cases PR, 5 cases SD and 2 cases PD, giving an overall response rate of 68.2%(15/22). The median time to progression was 7.0 months. The adverse reactions related to chemotherapy were tolerable; the most common toxic effects were marrow depression, alopecia, and fatigue. Conclusion: Low-dose continuous infusional PTX over 16-hours and 5-fu over 24-hours is a promising regimen with good tolerability in treating patients with advanced esophageal squamous cell cancer.

In this article, the author have studied on main revisions and some recommendations of the Incoterms(R) 2010. Main revisions are as belows. 1. Two new Incoterms rules -DAT and DAP- have replaced the Incoterms 2000 rules DAF, DES, DEQ and DDU. 2. New classification of the Incoterms(R) 2010 are adopted. First class is Rules for any mode or modes of transport(EXW, FCA, CPT, CIP, DAT, DAP and DDP belong to this class.) and second class is rules for sea and inland waterway transport(FAS, FOB, CFR and CIF belong to this class.). 3. Incoterms(R) 2010 rules formally recognizes that they are available for application to both international and domestic sale contracts. 4. The Guidance Notes and Introduction are not part of the actual Incoterms(R) 2010 rules. 5. Under the FOB, CFR and CIF, all mention of the ship's rail as the point of delivery has been omitted in preference for the goods being delivered when they are "on board" the vessel. 6. Incoterms(R) 2010 rules include the obligation to 'procure goods shipped' as an alternative to the obligation to ship goods in the relevant Incoterms rules. 7. Incoterms(R) 2010 rules give electronic means of communication the same effect as paper communication. 8. Incoterms(R) 2010 rules have allocated obligations between the buyer and seller to obtain or to render assistance in obtaining security-related clearances. such as chain-of custody information. Some recommendations are as belows. 1. The parties must incorporate the Incoterms(R) 2010 rules into their contract of sale. 2. The parties must choose the appropriate Incoterms(R) 2010 rules. 3. Specify the place or port as precisely as possible in their contract of sale. 4. Remember that Incoterms(R) 2010 rules do not give the parties a complete contract of sale. 5. Incoterms(R) 2010 rules do not prohibit alteration of Incoterms rule, but there are dangers in so doings. In order to avoid any unwelcome surprises, the parties would need to make the intended effect of such alterations extremely clear in their contract.

Objective: To observe the efficacy and toxicity of nanoparticle albumin bound paclitaxel (nab-paclitaxel) plus platinum agent (cisplatin or carboplatin) as first line treatment for stage III/IV squamous non-small-cell lung cancer (NSCLC). Methods: Forty chemotherapy naive patients with stage III/IV squamous NSCLC received nab-paclitaxel $125mg/m^2$ on day 1 and day 8, cisplatin $75mg/m^2$ on day 1, carboplatin area under the concentration-time curve of 5 (AUC=5) on day 1. One cycle of treatment was 3 weeks, and at least two were completed in each case. Results: Of the 40 patients who participated in the study, 25 achieved partial responses (PR), 12 reached a stage of stable disease (SD), and 3 suffered progressive disease (PD). The overall response rate (ORR) was 62.5% and the disease control rate (DCR) was 92.5%. Of the 20 patients without surgery or radiotherapy, 10 achieved PR, 7 reached a stage of SD, and 3 PD. The ORR was 50.0% and the DCR was 85.0%. The median progression-free survival time (PFS) of patients without surgery or radiotherapy was 5.0 months. Of the 20 patients receiving surgery or radiotherapy, 15 had PR and 5 p had SD, with an ORR of 75.0% and a DCR of 85.0%. Specifically, the DDP arm demonstrated a significantly higher ORR than the CBP arm (100%vs 54.5%, P<0.05). Common treatment related adverse events were myelosuppression, gastrointestinal response, baldness and neurotoxicity, most of which were grade 1 to 2. Conclusion: Nab-paclitaxel plus platinum agent (cisplatin or carboplatin) is effective as a first-line chemotheraphy for stage III/IV squamous NSCLC, and its adverse effects are tolerable.

Chemotherapy continues to be a mainstay of cancer treatment, although drug resistance is a major obstacle. Lipid metabolism plays a critical role in cancer pathology, with elevated ether lipid levels. Recently, alkylglyceronephosphate synthase (AGPS), an enzyme that catalyzes the critical step in ether lipid synthesis, was shown to be up-regulated in multiple types of cancer cells and primary tumors. Here, we demonstrated that silencing of AGPS in chemotherapy resistance glioma U87MG/DDP and hepatic carcinoma HepG2/ADM cell lines resulted in reduced cell proliferation, increased drug sensitivity, cell cycle arrest and cell apoptosis through reducing the intracellular concentration of lysophosphatidic acid (LPA), lysophosphatidic acid-ether (LPAe) and prostaglandin E2 (PGE2), resulting in reduction of LPA receptor and EP receptors mediated PI3K/AKT signaling pathways and the expression of several multi-drug resistance genes, like MDR1, MRP1 and ABCG2. ${\beta}$-catenin, caspase-3/8, Bcl-2 and survivin were also found to be involved. In summary, our studies indicate that AGPS plays a role in cancer chemotherapy resistance by mediating signaling lipid metabolism in cancer cells.

The presence of lung cancer cells in anoxic zones is a key cause od chemotherapeutic resistance. Thus, it is necessary to enhance the sensitivity of such lung cancer cells. However, loss of efficient gene therapeutic targeting and inefficient objective gene expression in the anoxic zone in lung cancer are dilemmas. In the present study, a eukaryotic expression plasmid pUC57-HRE-JAB1 driven by a hypoxia response elements promoter was constructed and introduced into lung cancer cell line A549. The cells were then exposed to a chemotherapeutic drug cis-diamminedichloroplatinum (C-DDP). qRT-PCR and western blotting were used to determine the mRNA and protein level and flow cytometry to examine the cell cycle and apoptosis of A549 transfected pUC57-HRE-JAB1. The results showed that JAB1 gene in the A549 was overexpressed after the transfection, cell proliferation being arrested in G1 phase and the apoptosis ratio significantly increased. Importantly, introduction of pUC57-HRE-JAB1 significantly increased the chemotherapeutic sensitivity of A549 in an anoxic environment. In conclusion, JAB1 overexpression might provide a novel strategy to overcome chemotherapeutic resistance in lung cancer.

The purpose of this study is to research consumers' perception of the HiSeoul fashion show, which is being used by new designers as a means of promotion, and to propose a strategy for revitalizing new designer brands. This was done in order to secure basic data from fashion consumers, to help guide marketing strategies and promote rising designers. In this research, the consumers' perception of HiSeoul fashion show was verified using text-mining, data refinement and word clouding that was undertaken by TEXTOM3.0. Also, semantic network analysis, CONCOR analysis and visualization of the analysis results were performed using Ucinet 6.0 and NetDraw. "HiSeoul fashion show" was used as the keyword for text-mining and data was collected from March 1, 2018 to April 30, 2019. Using frequency analysis, TF-IDF, and N-gram, it was also shown that consumers are aware of places where shows are held, such as DDP and Igansumun. It was also revealed that consumers recognize rising designer brands, designer's names, the names of guests attending the show and the photo times. This study is meaningful in that it not only confirmed consumers' interest in new designer brands participating in the HiSeoul Fashion Show through big data but also confirmed that it is available as a marketing strategy to boost brand sales. This study suggests using HiSeoul show room to induce consumer sales, or inviting guests that match the brand image to promote them on SNS on the day the show is held for a marketing strategy.

Unconventional computer vision and image processing techniques offer significant advantages for experimental applications to shaking table testing, as they allow the overcoming of most typical problems of traditional sensors, such as encumbrance, limitations in the number of devices, range restrictions and risk of damage of the instruments in case of specimen failure. In this study, a 3D motion optical system was applied to analyze shake table tests carried out, up to failure, on a natural-scale masonry structure retrofitted with steel reinforced grout (SRG). The system makes use of wireless passive spherical retro-reflecting markers positioned on several points of the specimen, whose spatial displacements are recorded by near-infrared digital cameras. Analyses in the time domain allowed the monitoring of the deformations of the wall and of crack development through a displacement data processing (DDP) procedure implemented ad hoc. Fundamental frequencies and modal shapes were calculated in the frequency domain through an integrated methodology of experimental/operational modal analysis (EMA/OMA) techniques with 3D finite element analysis (FEA). Meaningful information on the structural response (e.g., displacements, damage development, and dynamic properties) were obtained, profitably integrating the results from conventional measurements. Furthermore, the comparison between 3D motion system and traditional instruments (i.e., displacement transducers and accelerometers) permitted a mutual validation of both experimental data and measurement methods.

Purpose - The purpose of this study is to review and analyzes the contract of carriage and delivery/transport document in light of the major changes made to the Incoterms^® 2020 rules forced into effect on January 1st, 2020. Design/methodology - This study analyzed responsibility for the loading and unloading of goods under the contract of carriage in Incoterms 2020^® rules forced into effect by the ICC from January 1, 2020, and what document must be presented as evidence of delivery by the seller. Findings - A review revealed that in Rule C, the costs of unloading at the place of destination are determined by the terms of the contract of carriage, and in the DAP and DDP rules, if the seller bears the unloading costs, such unloading costs cannot be recovered from the buyer. To settle this issue, the seller needs to make a contract of carriage by sea with the carrier on FI terms. Furthermore, in the case of containerized goods that the FCA should be used, FOB was misused because the seller could not present an on-board bill of lading in the L/C transaction. However, it was confirmed that in FCA, the parties can use an optional mechanism to issue an on-board bill of lading. Originality/value - Incoterms 2020^® rules are still widely used in international trade by parties to contract sales around the world, just like Incoterms 2010^® rules. This study attempts to reduce or eliminate disputes that may arise from interpretative misunderstandings between the parties in the contract of sales concluded by the seller and the buyer.

Chloramphenicol에 대한 미분 펄스 폴라로그래피 분석법을 연구하였다. Chloramphenicol은 Ag/AgCl(포화 KCl) 기준전극에 대하여 0.00∼-1.50 Volt 영역에서 pH 의존성을 갖는 하나의 환원 피이크를 나타내었다. 실온(20$^{\circ}C$)에서 측정한 피이크 전위(Ep)를 Chloramphenicol 용액의 pH에 대하여 조시하였을 때 직선적인 관계를 보여주었으며 pH 8.9에서 기울기(Ep/pH) 변화를 나타내었다. 기울기는 pH 2.7∼8.9 사이에서 -59.7mV/pH이었고 pH 8.9∼11.2 사이에서는 -24.3mV/pH이었다. pH 8.0 암모늄완충용액을 지지전해질로 사용하여 4.8 ${\times}$ 10$^{-7}$ M and 6.2 ${\times}$ 10$^{-5}$ M (0.16 ppm∼20 ppm), Chloramphenicol 용액의 피이크 전류(ip)를 농도에 대하여 도시하였을 때 직선성을 나타내었다. Chlormaphenicol에 대한 미분 펄스 폴라로그래피법과 공정서 방법인 278nm에서의 자외선 흡수분광분석법 사이에 상관계수는 0.996으로서 우수한 상관관계를 나타내었다. Chloramphenicol을 약알칼리성(pH 8.0) 용액에서 장기간 보관시 분해 생성물의 검출은 미분펄스 폴라로그래피법이 분광분석법보다 용이하였다.
