  • The premise for the study reflected in this article is the need to dispose of industrial waste, which is increasingly being used in the construction materials industry. Also, dynamically developing building industry demands attention of scientists and a direction of their works on improvement of the technology of carrying out construction works. Thus, the article is devoted to studying the influence of various chemical additives and fine fillers (industrial wastes) available in Kazakhstan on self-compacting concrete (SCC) mixtures and its rheological, physical, and technical properties. According to the studies, revealed the most efficient type of fine-dispersed filler and the most optimal type of chemical additive to enable obtaining a high-quality SCC mixture based on local raw materials. As a result, the use of microsilica in comparison with other industrial wastes resulted in a conglomerate with high compressive strength of SCC at early terms of curing. In terms of economic efficiency and quality improvement, the results of study are of practical value for the manufacturers of ready-mixed concrete operating in Kazakhstan.

  • This article is concerned with choice-based conjoint analysis versus rating-based and ranking-based conjoint analysis. Choice-based conjoint analysis has a definite advantage in that the respondent's task of choosing the most preferred profile from several competing profiles adequately mimics consumer marketplace behavior. It is crucial to design the choice sets appropriate for the choice-based conjoint. Thus, this article suggests a new method to design the choice sets that are well-balanced. It augments the balanced incomplete block design and then obtains the dual design of the result to accommodate various numbers of profiles. In consequence, the choice sets designed by the new method have the desirable characteristics that each profile is presented to the same number of respondents, and pairs of any two distinct profiles occur together in the same number of choice sets. The balancing of the design increases the efficiency of the conjoint analysis. In addition, the pair-comparison scheme can improve the quality of data through the identification of contradictory responses.

  • This study focus on interest for arrears and filling of the gaps left in Article 78 of CISG. In the case of CISG, Article 78 provides for interest any time a payment under a contract is untimely, but does not specify a particular rate of interest or a method to determine such a rate. This issue did not cause any uncertainty under ULIS, the CISG's antecedent, since Article 83 of ULIS provided for 1%p above the official discount rate in the creditor's country. Lacking any CISG general principle as well as any indication by the very same CISG, one can only conclude that the matter must be deferred to the domestic rule of private international law. Actually, resorting to private international law is not only admissible, but expressly required by Article 7(2). In the interpretation and filling of the gaps left in Article 78, there is a considerable difference of opinion especially amongst commentators on whether the gap is a lacuna praeter legem, i.e., one being governed by, but not expressly settled in the CISG, or whether it is an issue falling outside the scope of application of the CISG, i.e. a lacuna intra legem. The protagonists of the former view lay emphasis on the overall objective of the CISG, namely to create a uniform law, whereas the supporters of the latter view refer to the legislative history of Article 78 as the dominant principle in interpreting Article 78. Some authors believe that the issue of determining the rate of interest is not dealt with by CISG and it is, therefore, governed by the applicable domestic law, which is the subsidiary law applicable to the sales contract, since "no special connecting points seem to have developed for the entitlement to interest." In the light of the relevant case law, it seems correct to conclude that the interest rate is not determined by CISG and that courts normally determine it according to their own rules of private international law. While CISG Article 78 expressly does not deal with this issue, PICC Article 7.4.9 and PECL Article 9.508, on the other hand, set forth a precise method for computing interest. Although a method like the one set by PICC may be useful and may encourage uniformity, it still cannot be used under the CISG. The PICC or PECL formula may, however, be a very good starting point in a de jure condendum analysis when a new Article 78 will be drafted, if an interest rate method will ever be embodied in the text of an international convention.

  • There can be analyzed severally on the acceptance conditions of freight forwarder's transport document under UCP. First, Bills of Lading issued by forwarding agents will be refused. This can be seen in the article 20 of 1933 Revision UCP(Brochure 82) and the article 20 of 1951 Revision UCP(Brochure 151). Second, Unless specifically authorized in the credit, Bills of Lading issued by forwarding agent will be rejected. It is prescribed in the front part (a) of article 17 of 1962 Revision UCP(Brochure 222) and the article 19 of 1974 Revision UCP(Publication No. 290). Third, Acceptance conditions are different according to the type of transport documents, that is either Bill of Lading or not. It is prescribed in the art 25 and article 26 of 1983 Revision UCP. Unless otherwise stipulated in the credit, transport document issued by a freight forwarder will be rejected unless it is the FIATA Combined Transport Bill of Lading approved by the International Chamber of Commerce or otherwise indicates that it is issued by a freight forwarder acting as a carrier or agent of a named carrier. On the other hand, unless otherwise stipulated in the credit, marine bill of lading issued by a freight forwarder will be rejected, unless it indicates that it is issued by such freight forwarder acting as a carrier, or as the agent of a named carrier. Fourth, transport documents issued by a freight forwarder will be accepted. This can be found in the article 30 of 1993 Revision UCP(ICC Publication No. 500) and the article 14 l of 2007 Revision UCP(ICC Publication No. 600). According to the former unless otherwise authorized in the Credit, transport document issued by a freight forwarder will only be accepted if it is appears on its face to indicate the name of the freight forwarder as a carrier or multimodal transport operator or its agent. The latter prescribed that a transport document will be accepted if it is issued by a freight forwarder by a agent of carrier or freight forwarder itself.

  • 연구자의 연구 성과와 저널의 영향력을 평가 할 수 있는 계량서지 지수는 매우 중요하다. 하지만 이들은 특징이 모두 다르기 때문에 저널을 선택할 때 여러 가지 지수를 함께 고려할 필요가 있다. 이를 위해 본 연구에서는 피어슨 상관분석을 통해 각 지수들을 비교 분석하여 이들 간의 관계를 보여주고자 한다. 이를 위해 상관 분석을 주제와 Article Influence Score(AIS) 순위에 따라 수행하였다. Total Cites와 Eigenfactor Score, Article influence Score와 5-Year Impact Factor의 상관분석 결과를 주제에 따른 평균값으로 살펴보았을 때, 이들은 매우 높은 상관관계가 있었다. 또한 Article influence Score와 5-Year Impact Factor의 경우, 모든 주제에서 AIS 순위에 따른 상위 25% 구간에서 두 지수 간에 상관관계가 매우 높은 것으로 나타났다.

  • EAS (electronic article surveillance) 시스템은 상품의 도난 방지를 위한 것으로 상품 판매 자동화 증가로 인해 사용이 급속히 늘어나고 있다. 이에 본 연구에서는 EAS 시스템의 전자기장 세기를 측정하였고, EAS 시스템이 pacemaker와 ICD에 미치는 영향에 대해 알아보았다. 일반 성인 심장 높이인 130cm에서 6.3 kHz와 14.25 kHz EAS 시스템의 게이트 안쪽의 왼쪽, 바깥쪽의 오른쪽과 가운데 위치에서 전자기장의 세기를 측정하였고, pacemaker와 ICD의 동작 여부를 관찰하였다. 측정 결과 전자기장의 세기는 EAS 시스템에 따라 큰 차이가 났는데 14.25 kHz를 사용하는 EAS 시스템이 가장 강했다. Pacemaker는 고정시 세 위치 모두에서 파형 변화가 관찰되었고, ICD는 이동시와 고정시한 위치에서만 noise reversion, 심실세동이 관찰되었으며, 모두 전자기장 세기가 가장 센 14.25 kHz의 EAS 시스템의 전자기장에 의해 발생하였다. 이에 현재 국내에서는 시행되고 있지 않은 전자기장 방출에 대한 안내문 부착과 이식형 의료기기 시술을 받은 환자의 접근에 대한 위험성 경고문 등의 조치가 필요하다.
