  • This study primarily concerns the seller's duty to deliver the goods in conformity with the contract under the United Nations Convention on International Sale of Goods(1980) in comparison with the Draft Principles of European Sales Law. It describes and analyzes the provisions of the CISG as to the seller's duty, focusing on main controversial issues among scholars in their application. It also attempts to compare the rules of the CISG with those of the Draft PESL and to evaluate them in light of the discipline of comparative law. This is for the purpose of facilitating the systematic development and reform of one jurisdiction by any solution from the other jurisdiction found by the comparative study. In addition, this study provides legal and practical advice to the contracting parties when they intends to insert the CISG or the Draft PESL in their contract as a governing law. The comparative study particularly focuses on the following aspects; first, requirements for conformity with the contract which deals with the concept of conformity with the contract, contractual requirements agreed between contractual parties, and implied requirements otherwise not agreed between contractual parties, second, the time when the goods must be in conformity with the contract, third, exclusions of the seller's duty to deliver the goods in conformity with the contract.

  • Transformer models have had a great impact on natural language processing (NLP) in recent years by realizing outstanding and efficient contextualized language models. Recent studies have used transformer-based language models for various NLP tasks, including Persian named entity recognition (NER). However, in complex tasks, for example, NER, it is difficult to determine which contextualized embedding will produce the best representation for the tasks. Considering the lack of comparative studies to investigate the use of different contextualized pretrained models with sequence modeling classifiers, we conducted a comparative study about using different classifiers and embedding models. In this paper, we use different transformer-based language models tuned with different classifiers, and we evaluate these models on the Persian NER task. We perform a comparative analysis to assess the impact of text representation and text classification methods on Persian NER performance. We train and evaluate the models on three different Persian NER datasets, that is, MoNa, Peyma, and Arman. Experimental results demonstrate that XLM-R with a linear layer and conditional random field (CRF) layer exhibited the best performance. This model achieved phrase-based F-measures of 70.04, 86.37, and 79.25 and word-based F scores of 78, 84.02, and 89.73 on the MoNa, Peyma, and Arman datasets, respectively. These results represent state-of-the-art performance on the Persian NER task.

  • Purpose - This paper examines how differently output and input tariffs affect domestic employment across industrial characteristics of comparative advantage such as labor quality and capital intensity. Design/methodology - The paper focuses on 453 Korean industries from 2007 to 2014 because Korea is a typical example of a natural resource-scarce open economy and experienced the transition of the export pattern from labor intensity to technology intensity during this period. Findings - The results show that input tariff reduction stimulated total employment, focusing on the early 2010s, while the effects of output tariff reduction were statistically insignificant in general. However, the stimulation effects of output tariff reduction on employment were found in comparative advantage industries with greater labor quality and capital intensity. As for input tariff reduction, its stimulation effects on employment were more prominent in comparative disadvantage industries with lower labor quality and capital intensity. Originality/value - These results provide significant implications for natural resource-scarce open economies which are experiencing the transition of the export pattern from labor intensity to technology intensity and the unequal distribution of income after trade liberalization: imported intermediate inputs has become increasing important, leading to trade effects on employment and alleviation of income inequality.

  • Menthae herba (MH) extracts exhibit anti-inflammatory effects. The purpose of this study was to determine whether the anti-inflammatory effects of MH extracts vary according to the cultivation regions. We performed a comparative analysis of MH extracts by evaluating the production of inflammatory mediators in RAW 264.7 murine macrophage cells and HaCaT human keratinocyte cells. MH extracts obtained from different cultivation regions in Korea and China significantly reduced the production of nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$), and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in RAW 264.7 cells stimulated with lipopolysaccharide (LPS). No differences in these inhibitory activities were observed between MH extracts. In HaCaT cells stimulated with TNF-${\alpha}$ and interferon-${\gamma}$ (IFN-${\gamma}$), MH extracts did not inhibit the production of macrophage-derived chemokine (MDC/CCL22), but most extracts reduced the production of the regulated on activation normal T-cell expression and secreted (RANTES/CCL5). We used clustering tree analysis of the MH extracts according to the chromatographic pattern and anti-inflammatory potency of MH extracts. We observed differences in the chromatographic pattern of MH extracts but no difference in anti-inflammatory potency. Our findings suggest that MH extracts from different regions do not show any differences in their pharmacological potency in that MH extracts are used as therapeutic agents to treat inflammatory disorders.

  • Objectives: The purpose of this study was to investigate and analyze the demands for educational programs on clinical trials of Korean medicine devices, and develop training programs based on the needs of Korean medicine. Methods: This research was conducted targeting 26 volunteer applicants who had participated in clinical trials of Korean medicine devices within the last five years (2010-2015). The survey was carried out between May 1, 2015 and May 26, 2015 via e-mail. After receiving questionnaire replies, the material was established. Using obtained data, frequency analyses were performed using SPSS 20.0 version. Results: 92% of the researchers who participated in the survey expected introduction of educational programs on clinical trials and anticipated that programs contain information that can meet the needs of each researcher. In addition, according to the analysis, introducing expert certification for clinical trials of Korean medicine devices is necessary, and offering related graduate courses are also needed. Conclusions: As a result of this study, researchers had difficulties during clinical trials of Korean medicine devices. If the educational programs were to be developed and institutional frameworks support them effectively, it would prove to be helpful to researchers in clinical trials.

  • The purpose of this thesis, therefore, is to examine the shaping methods and the knitting drafts of sleeve cap in the knitwears which are currently used by the manufacturers; to study the curve forms of sleeves in knitwears by analyzing synthetically the results of investigating the problems of knit wear sleeves; to present the most suitable sleeve cap for the knitwears. As the studying methods, I collected the basic data from the working-level persons of knit wear manufacturers, examined the knitting draft in the knitwears, and from that, made three kinds of comparative experimental garments and one kind of research experimental one as 10G and 16G. In doing so, I showed the sleeve cap suitable for the knitwears with plain stitch after operating sensual evaluation with Liker's 5-point rating measure. The analysis of data was handled with statistics by using SPSS Ver. 12.0; the method of statistics was executed by Frequency Analysis, Trust Analysis, one-way ANOVA, and Duncan test according to each topic of the research. As the result of the sensual evaluation of the experimental garments produced from the study, the research experimental garment looks better than the comparative experimental one in both 10G and l6G; has less extra folds around the front part of sleeve cap; looks more natural in sleeve caps of the body part and of a sleeve. From this, I am able to figure out that the research experimental garment looks better than the comparative experimental one produced by knit wear manufacturers. In addition, I can come to know that the different knitting of the front line and the back one of armhole in the knitwears has a favorable impact on improving the appearance of a sleeve.

  • Comparative studies of histopathologic lesions from 23 purified protein derivative (PPD) positive cattle, 21 slaughter cattle found with tuberculosis, and 11 tuberculosis-positive elk (Cervus elaphus) were performed. PPD positive cattle did not show specific histopathologic lesions in all 23 heads that were no visible lesion reactor. Slaughter cattle found with tuberculosis revealed microscopically classical granulomatous lesion (tubercle) with central caseous necrosis surrounded by mantle of epithelioid cells and Langhan's giant cells capsuled by connective tissue in lung. Elk was noted with some different lesion patterns with classical granulomatous lesion and suppurative abscesses that was composed of fibrin, degenerated cells without having connective tissue. In addition, many Langhan's giant cells infiltration in alveoli at peripheral lesion were observed in some cases of classical granulomatous lesion and suppurative abscesses.
