The purpose of this paper is to suggest fundamental data for finding problems and ways to improve Korean dental infection control studies through the classification of literature on dental infection control which have been conducted in Korea. The collection of literature was done via seven online database programs only for domestic literature. The date of first search was September 16-17th, 2009, and the final search was completed on December 20th, 2009. (1) From the examination of the frequency of research according to the publishing form by year, it is revealed that after 2006, dental infection control is being performed most vigorously, compared with 1980's when the studied on this area started. (2) According to the classification of research method by research design of original article among the literature, original articles were 45 studies, and the others were 20 studies. It was also found that in 45 studies of original article, there were 37 studies of survey research, and there were 8 studies which include microbiology examination. (3) On the analysis of the subject of each study, glob and mask using rate have gradually increased, and the frequency of pierced with sharp implement or needle have gradually decreased. Through this research, it can be observed roughly how the results depended on subject of each studies change. However, it may be restricted to generalize the results of this research, because there are lack of clear standard and literature evidence to assess the interrelationship between each study. Also, since there are shortage of research and studies in dental infection control, the research to examine the effects should be tried actively after the standards and precaution of dental infection control developed.

This article is subject to the rationalization of the cold-storage warehouse management, which gives the stabilization of the fishery production and the food life with respect to fisheries industry. In this point of view, the article examines to the structure of the cold-storage warehouse industry from the perspective of the industrial organization. To put it concretely, the article intends to apprehend the state of the structure of the industry and analyze the cold-storage warehouse's management activities. In addition, I try to find know the factors that affect the management performance(profitablity) of the industry through the cross-sectional correlation analysis. Finally, the conclusion of the article can be described as follows : \circled1 On the basis of the cold-storage capacity, there is the tendency that the industry concentrate in the area of Pusan(41.7%). \circled2 By formulating step of development of the industry, it is divided by six types. Type I is designed as raw material-storage warehouse for self-processing. Type IIis the raw material-storage warehouse for self-processing and storage-sale warehouse. Type III is the raw material-storage warehouse for self.distribution. Type IV is the raw material-storage warehouse for self-distribution and storage-sale warehouse. Type V is the net storage-sale warehouse. Type Ⅵ is the physical distribution center warehouse. Although each region has one representative type,6 types exist in all regions. \circled3 The competition structure of the industry has double structure on the basis of cold-storage capacity. \circled4 With respect to the management activity of the cold-storage warehouse, there is no change or even a decrease not increasing or not any change in sales from 1996 to 1997 \circled5 In order to try to induce the amount of shipper's materials, services that a cold-storage warehouse supply with its users include a custody-fee discount, a distribution-process service, a finance service, quality management service and so on. One of the best attractive services is the custody-fee service. \circled6 In the structure and management activity of the industry, the factors that affect management performance (profitablity) are a custody-fee discount, sales ability and capital structure of individual firm. Positive factor is sales ability and capital structure of individual firm. But, The custody-fee discount turns out to be a negative capital structure of individual film.

Educational reform in Ukraine encourages the use of multimedia technologies in the training of specialists in Physical Education and Sports, which is one of the promising directions of education development. Therefore, the article specifies the content of the terms "innovation" and "technology". For modern society, the introduction of multimedia technologies in education is not so much theoretical as pragmatic, since under condition of globalization it concerns its historical development and prospects associated with the so-called "high technologies".Our goal is to improve the training of Physical Education and Sports specialists by means of multimedia technologies. All of innovative technologies can be divided into four groups, depending on the appropriate form of educational activity for their use. The development of multimedia technologies in the training of specialists in Physical Education and Sport at the present stage of education development should be carried out in accordance with the criteria of manufacturability, which are presented in the article: scientism, to rely on the theoretical provisions of pedagogical science and methods of teaching the discipline, socially recognized educational goals, prospects for modernization of Education; consistency, which provides for the interaction of parts and the whole in the organization of the study environment, as a result of which the physical development of the young generation is an integral entity; guarantee, that is, the error between the planned and obtained results should be minimal; manageability, that is, full management of the stages of work of the teacher and students, which make up the completed cycle of actions; mass participation, for the purpose of applying the technology does not depend on the physical training of students, the pedagogical skill of the teacher and the type of educational institutions. The article presents the theory and method of organizing sports events and circuses in the training of specialists in Physical Education and Sports by means of multimedia technologies. In order to increase the level of physical development of a person, physical fitness and the state of health of students, which has a clear trend to constant deterioration, it is necessary to instill love for sports, carry out high-quality training and organize sports events using multimedia technologies. In the process of sports activities, the participants' mental education is carried out. There are two types of communication here: direct and indirect, which are described in the article.In games and sports competitions, there are many opportunities for forming rules of collective behavior. The main issues of the organization of sports activities by means of multimedia technologies have been clarified. During sports competitions, the tasks presented in Physical Education and sports classes are improved, which ensure the improvement of physical and theoretical training of the individual. The pleasure of sports, bright, emotional spectacles, confirmed by multimedia technologies, arises from the participation of the viewer in them.

The Korean government enacted the Chapter 6 as of Air Transportation to the Korean Commercial Act, which was enforced in 2011, in order to treat some arguments occurred from air transportation Contracts since air transportations has rapidly increased in Korea. Air transportations has been used more in the field of international market than in the field of domestic market under it's own characteristic. Therefore, many international agreements and protocols related to the air transportations has been appeared from old times and the 1999 Convention for the Unification of Certain Rules for International Carriage by Air ("Montreal Convention") is one of them. The Montreal Convention was adopted in May 28, 1999 at International Conference of Air Law hosted by the International Civil Aviation Organization ("ICAO") in Montreal, Canada where the Headquarter of ICAO is located. The Montreal Convention has been effected from September 5, 2003 and the Korean government ratified the convention in 2007. Therefore, the Montreal Convention came in to force in Korea since 2007. This year, 2017, is the 10th anniversary year since the Montreal Convention has taken effect in Korea. However, there are rare cases that argued the Montreal Convention's scope of application and this Article examines the Korean Supreme Court's case that argued the Convention's scope of application. Thus the Article basically analyzes the case from the perspective of the Montreal Convention's scope of application and examines the Montreal Convention's articles related to the air carrier's liability and extent of compensation for damage that occurred from the international carriage by air. Also this Article analyzes the Korean Commercial Act Chapter 6, which regulated the air carrier's liability and the Article tries to make a comparison between the Montreal Convention and the Korean Commercial Act in order to draw some scheme for the betterment of Korean Commercial Act. It is the hope that the Article contribute to the improvement of Korean Commercial Act through the comparison with the chance of the 10th Anniversary of the Montreal Convention in Korea.

Given operators X and Y acting on a Hilbert space $\mathcal{H}$, an interpolating operator is a bounded operator A such that AX = Y. In this article, the following is proved: Let $\mathcal{L}$ be a subspace lattice on $\mathcal{H}$ and let X and Y be operators acting on a Hilbert space H. Let P be the projection onto the $\overline{rangeX}$. If PE = EP for each E ${\in}$ $\mathcal{L}$, then the following are equivalent: (1) sup ${{\frac{{\parallel}E^{\perp}Yf{\parallel}}{{\parallel}E^{\perp}Xf{\parallel}}}:f{\in}\mathcal{H},\;E{\in}\mathcal{L}}$ < ${\infty},\;\overline{rangeY}\;{\subset}\;\overline{rangeX}$, and there is a bounded operator T acting on $\mathcal{H}$ such that < Xf, Tg >=< Yf, Xg >, < Tf, Tg >=< Yf, Yg > for all f and gin $\mathcal{H}$ and $T^*h$ = 0 for h ${\in}\;{\overline{rangeX}}^{\perp}$. (2) There is a normal operator A in AlgL such that AX = Y and Ag = 0 for all g in range ${\overline{rangeX}}^{\perp}$.

The purpose of this article described the effects of mentoring program to the underachiever's attitude in learning Mathematics. In order to do this research, a mentoring class had been carried out for 30 weeks, with two students who was underachievers in mathematics. It was carried out contrastive analysis on the student's learning attitude in the math class before and after the mentoring, using a questionnaire of learning attitude in math with 40 questions, filling the blanks in sentence, recording files of class, and mentoring journals. As a result, before taking the mentoring class, students who were participated in the mentoring program were negative and low in five subordinate concepts(learning attitude, such as their tendency, interest, desire, confidence, attitude, and studying habits in math). However, after the mentoring class, the two students were remarkably changed in positive way on the five concepts in learning mathematics. Therefore, it is helpful to underachievers in mathematics if the mentoring program is used since it yields a positive impact on the learning attitude.

An arbitrator in Pakistan is required to file an arbitral award in a civil court of competent jurisdiction for its recognition and enforcement if an arbitral award is domestic or before the concerned High Court if the arbitral award is international. The court of law is required to issue a decree upon submitted arbitral award if an interested party do not apply for modification or remission of an arbitral award and do not challenge it for setting it aside or for revocation of its recognition and enforcement within a prescribed time limit. The challenging process of an arbitral award can be started by the aggrieved party of an arbitration agreement at the seat of arbitration or at the place where recognition and enforcement of an arbitral award is sought. The aggrieved party to an arbitration agreement is required to challenge an arbitral award within a prescribed time limit if contracting parties have not excluded the right to challenge an arbitral award. Limitation for challenging an arbitral award in Pakistan is 30 days under article 158 of the Limitation Act 1908, starting from the date of service of notice of filling of an arbitral award before the court of law. Generally, 90 days are given for an appeal against decision of the civil court of law under section 96 of the Code of Civil Procedure 1908, it is therefore highly recommended that challenging time of an arbitral award should be increased from 30 to 90 days.

As arbitration is widely used as an alternative dispute resolution mechanism, third-party funding, which is a person or entity with no prior interest in the legal dispute providing non-recourse financing for one of the parties, has become more prevalent with increasing costs of international arbitration. In particular, Hong Kong and Singapore are the first jurisdictions to adopt and implement legislations to specifically permit third-party funding of international arbitration. Thus, in this article, relevant issues with respect to third-party funding of arbitration, such as, conflicts of interest, disclosure, privilege and confidentiality of information, cost allocation, security for costs, and control over arbitral proceedings by the third-party funder are examined with pertinent provisions of the recent legislations. While the respective legislations of Hong Kong and Singapore may not directly address every issue raised by third-party funding of arbitration, as they make it clear that such is no longer prohibited by the old common law doctrines of champerty and maintenance, they have clarified conflicting case law as well as proactively promoted themselves as leading seats of international arbitration.
