Purpose - This paper studies whether economic sanctions can be used as grounds for a party to an international sales contract to get an exemption if he fails to meet his contractual obligation. Because the answer can differ depending on the governing law of the contract, this study focuses on CISG, the most widely recognized international uniform legal instrument as the governing law of the international sale of goods. Design/methodology - This paper focuses on analyzing the conditions to meet before getting an exemption under CISG. For such analysis, this paper examined various scholarly writings, cases, and hypothetical examples reflecting a wide variety of economic sanction measures. Findings - The findings of this paper are as follows. The main provision for exemption under CISG is Article 79(1), which provides for an exemption for a party that failed to perform if such failure was caused by an impediment that was uncontrollable, unforeseeable, and unavoidable; either a seller or a buyer may rely on the Article for his non-performance, delay, or defective performance. The Article is applicable not only where the economic sanction caused impossibility of performance but also where it caused hardship. The economic sanction will likely be found to be an uncontrollable impediment; however, it will be relatively more difficult to prove it to be unforeseeable or unavoidable. Originality/value - The subject of this paper is whether a party can be exempted from liability under CISG when he fails to perform his contractual obligations due to economic sanctions. Given that this issue is now actually faced by many involved in international trade, it is expected to provide practical help to practitioners and companies alike.

Fashion stores have to change to fit such the taste of individual customers taste and try to give unique experiences to the customers. They need to develop a special space that entertains customers, and entices them to visit and revitalize the off-line stores. This paper aims to analyze the experimental factors of stores, and how each of the factors impact customer experience in order to find out its effect on store satisfaction and store loyalty. Data was analyzed by using SPSS 18.0 and AMOS 18.0. Results of this study are as follows. First, Visual, Tactile, and Gustatory are the main senses that influence the emotional experience of the customers on a store visit. Second, three factors that influenced customer experience in experimental fashion stores are 'Causing Interest', 'Causing Concern', and 'Causing Relationship.' Third, the 'Causing Interest' factor and the 'Causing Concern' factor showed positive correlation with store satisfaction, while the 'Causing Relationship' factor did not impact store satisfaction, which affected store loyalty. Fourth, each experimental fashion stores can have different effect to consumer satisfaction and loyalty. Also, fashion store brands without an experimental store can cause various effects to consumers when a flagship store with an array of product information is formed. The conclusion drawn from this study will provide a guideline for fashion stores attract faithful customers by improving their store environment.

As a method to satisfy needs and emotions of consumers who pursue diversity, the use of Kitsch in the fashion industry has been increased. Previous studies on Kitsch fashion have focused on qualitative research on the characteristics of Kitsch product, and little empirical researches have been conducted on consumer attitude such as consumer response to Kitsch products and brand equity. Therefore, the purpose of this study are 1) to investigate comparisons of experiential values (i.e., Aesthetic, Amusing, Cultural) with Kitsch product moderated by consumers' characteristics (i.e., consumer uniqueness, fashion involvement), and 2) to explore the relationship between experiential values and brand equity. Factor analysis, reliability analysis, ANOVA, and structural equation model using SPSS 18.0 and AMOS 18.0 were used for the data analysis. 210 questionnaires were analyzed for this study. The results of this study were as follows. First, significant difference in aesthetic values of Kitsch products were shown. Kitsch Product with nostalgic characteristics has higher aesthetic values than others. Specifically differences in experiential values with Kitsch product were partially moderated by consumers' characteristics (i.e., consumer uniqueness, fashion involvement), Second, cultural value had a positive influence on brand awareness, while amusing and cultural values had a positive influence on brand image. Also aesthetic and amusing values had a positive influence on brand loyalty. Academic and business implications were discussed from this study.

Poly(ether block amide) (PEBA)는 이산화탄소 분리에 매우 적합한 상용 블록 공중합체 중 하나이다. 기체분리막의 경우 높은 투과도 뿐 아니라 강한 기계적 강도 또한 필요로 한다. PEBA공중합체의 결정성 폴리아마이드(polyamide) 블록은 기계적 강도를 제공하며 동시에 rubbery한 폴리에테르(polyether) 부분은 이산화탄소와의 친화도를 부여하여 이산화탄소 촉진 수송에 기여한다. PEBA공중합체에서 결정성 상과 rubber한 상의 조성은 기체분리막에 적합하게 조절될 수 있다. PEBA 공중합체를 기반으로 한 분리막은 좋은 투과도를 갖지만 추가적으로 분자체 효과를 이용하여 큰 기체 투과도 손실 없이 분리막의 선택도를 향상시킬 수 있다. 혼합 매질 분리막은 혼합막의 한 종류로서 고분자 매트릭스와 유기 첨가제로 이루어져 있다. 하지만 고분자 매트릭스와 유기 첨가제간의 양립성(compatibility)에 따른 문제점 또한 존재한다. 따라서 본 총설에서는 PEBA 공중합체를 기반으로 한 혼합막의 장점과 한계에 대해 다루고자 한다.

지구 온난화 이슈에서 가장 고질적인 문제 중 하나는 온실가스의 배출이다. 다양한 온실 가스 중 가장 높은 비중을 차지하는 이산화탄소(CO₂)는 이를 분리하기 위해 연구자들이 지속적으로 연구를 진행해오고 있다. 이러한 관점에서 본 연구에서는 이산화탄소 기체를 분리하기 위해 poly(vinyl alcohol) (PVA) 기반 공중합체를 제조하여 기체 분리막에 활용했다. 공중합체는 자유 라디칼 중합법을 활용했으며, 곁사슬을 위한 단량체로 아크릴산(acrylic acid)를 사용하여 PVA-g-PAA(VAA) 그래프트 공중합체를 제조했다. 본 공중합체를 이산화탄소 기체분리막에 적용한 사례는 최초이며, 폴리설폰 지지체에 복합막 형태로 제조했다. 공중합체 합성 결과는 FT-IR을 통해, 합성한 공중합체 의 거동은 TEM과 DSC, TGA를 통해 분석하였다. AA 그래프팅을 통해 공중합체는 나노 구조를 형성하며, PVA의 결정화도를 급격하게 감소시켜 이산화탄소의 용해도를 증가시켰고, 이는 이산화탄소 기체 분리 성능을 향상시켰다. 이를 통해 이산화탄소 분리막 분야에 용액-확산 및 그래프팅 방법이라는 새로운 접근법을 제시하였다.

Purpose - This paper studies whether CISG can be a suitable governing law for pure service contracts. When CISG was first drafted, there was little disagreement on the fact that contracts for the sale of goods and those for the provision of services were two different types of contract. Based on this understanding, CISG explicitly provides that the Convention will apply to contracts where the preponderant part of the contractual obligation is on the sale of goods, not services. However, as more sales transactions have come to include more elements of services, mainly due to the advancement of the IoT industry, the distinction between goods and services became more blurred. Based on the observation of recent changes, some scholars even argue that such a change supports the applicability and suitability of CISG to even pure service contracts. The purpose of this paper is to critically analyze and evaluate their argument. Design/methodology - This paper focuses on two separate but related issues: CISG's 'applicability' and 'suitability' to service contracts. For the first issue, this paper will examine the rules of interpretation of international treaties under the Vienna Convention on the Law of Treaties of 1969, and will apply its rules to find the proper answer. For the second issue, this paper will perform logical and empirical analyses on the reasoning employed by scholars claiming the suitability of CISG to service contracts. Findings - This paper concludes that CISG does not, and should not, apply to pure service contracts. The argument that CISG applies to pure service contracts directly contravenes Article 3(2) of the Convention, which expressly states that it does not apply to a contract wherein the preponderant part of its obligation is about services rather than sales. Similarly, CISG is not a suitable governing law for pure service contracts because it aims provide rules specifically tailored to the needs of transactions of sales of goods, not services. Servitization of sales of goods transaction does not change this conclusion. Originality/value - This paper presents different views from those offered by some eminent scholars on the issue of applicability and suitability of CISG to service contracts. By doing so, it is hoped that the confusion caused in discussions so far are clarified. Hopefully, this paper can also provide practical guidance to practitioners engaged in the fields of international sales, services, and IoT industries.
