  • Purpose - The purpose of this study is to suggest a risk factor that significantly explains foreign currency risk premia. In recent years, some studies have found that the performance of the simultaneous consumption risk model improves considerably when tested on foreign currency portfolios, which are constructed based on the international interest rates differentials. However, this paper focuses on the long-run consumption risk factor. In our empirical research, we found that the real excess returns of high interest rate currency portfolios depreciate on average, when the future American long-run consumption growth rate appears low. This makes the high interest rate currency portfolios have relatively high risk premia. Meanwhile, the real excess returns of low interest rate currency portfolios appreciate on average, under the same conditions, which results in relatively low risk premia for these portfolios. Therefore, this long-run consumption risk factor might explain why low interest rate currencies do not appreciate as much as the interest rate differential, and why high interest rate currencies do not depreciate as much as the interest rate differential. Research design, data, methodology - In our explanation, we provide new evidence on the success of long-run consumption risks in currency risk premia by focusing on the long-run consumption risks borne by American representative investors. To uncover the hidden link between exchange rates and long-run consumption growth, we set the eight currency portfolios as our basic assets, which have been built based on the foreign interest rates of eighty countries. As these eight currency portfolios are rebalanced every year, the first group always contains the lowest interest rate currencies, and the last group contains the highest interest rate currencies. Against these basic eight currency portfolios, we estimate the long-run consumption risk model. We use recursive utility framework and the stochastic discount factor that depends on the present value of expected future consumption growth rates. We find that our model is optimized in the two-year period of constructing the durable consumption expectation factor. Our main results surprisingly surpass the performance of the existing benchmark simultaneous consumption model in terms of R2, relatively risk aversion coefficient γ, and p-value of J-test. Results - The performance of our model is superior. R2, relatively risk aversion coefficient γ, and p-value of J-test of our long-run durable consumption model are 90%, 93%, and 65.5%, respectively, while those of EZ-DCAPM are 87%, 113%, and 62.8%, respectively. Thus, we can speculate that the risk premia in foreign currency markets have been determined by the long-run consumption risk. Conclusions - The aggregate long-run consumption growth risk explains a large part of the average change in the real excess returns of foreign currency portfolios. The real excess returns of high interest rate currency portfolios depreciate on average when American long-run consumption growth rate is low, and the real excess returns of low interest rate currency portfolios appreciate under the same conditions. Thus, the low interest rate currency portfolios allow investors to hedge against aggregate long-run consumption growth risk.

  • Purpose: The purpose of this study is to analyze the research trends of domestic research ethics and to draw implications for the limitations of existing research and future development directions through this. Research design, data and methodology: To this end, this study first examined the concept of research ethics and research area to derive an analysis frame. In addition, 72 academic papers published in domestic journals from 2000 to November 2020 were analyzed according to the research period, research area, research subject, research field, research method, and the nature of the journal. Results: As a result of the analysis, it is judged that social interest in research ethics led to academic interest after the 2005 Hwang Woo-seok incident. These characteristics show that the interest of academia is changing and increasing significantly when issues related to research ethics are raised socially. Of the 72 papers to be analyzed, 29 (40.3%) conceptual and theoretical studies on research ethics and 43 (59.7%) studies on practical measures were surveyed. Conclusions: In the case of published journals on research ethics, the proportion of publications in humanities and social sciences and pedagogical journals was high, and in research methods, literature and theoretical studies were the highest.

  • This study examines the appearance management attitude factor of male college students and groups them according to their characteristics. Then this research analyzes their interest in knitwear, buying behavior, and characteristics to see what kind of differences exist. The results of the research are as follows: First, after conducting a factor analysis to identify the appearance management attitude of male college students, 3 factors emerged(sought personality, pursued trends, and appearance interest). Second, as a result grouping the students according to their attitude. It is created 3 groups(fashionista group, personality group, and appearance interest group). Third, for the interest in knitwear, the fashionista group had the highest interest in knitwear, with a preferred brand when purchasing. Fourth, the fashionista group that values personality and latest trends was more likely to purchase knitwear than the personality group or the appearance interest group. Finally, the majority preferred solid colors. Over 50% of the students preferred knits without any patterns. Also, the most preferred 100% cotton. As this survey was only surveyed in Seoul and Gyounggi areas. The next research requires to be surveyed in a more comprehensive area. Additionally, male college students must more effectively be segmented and surveyed to get accurate results.

  • Shape Memory Alloys have attracted the interest of a great number of researchers in the world, and Mexico is not the exception. Research in this field started ten years ago, and is actually an active line covering the classical Cu-based and Ti-Ni alloys, but also the new Fe-based alloys. Although more basic studies have been performed at the present time, interest for applied research and technological goals is increasing. In this work we present a series of studies carried on these Shape Memory Alloys by the groups in Mexico, and explain what the interest of our groups are in the next future in this are of the Materials Science. Interdisciplinary work has been necessary in the characterization of the different alloys, and multiple techniques have been used, like Mossbauer spectroscopy, thermoelectric power, electron microscopy, ultrasound techniques, neutron and x-ray diffraction, calorimetry, among others. Collaboration With other groups in Europe and in the United States have become highly useful and productive, and some examples of such activities are also reported.

  • This study examines underwear purchase behaviors and the attitude of male consumers based on the degree of interest in appearance. Data research was conducted on 296 males in their 20s and 30s located in Seoul & Gyeonggi province. The SPSS 17.0 software program was used to conduct data analyses such as descriptive statistics, frequency analysis, factor analysis, cluster analysis, t-test, and $\chi^2$-test. The results of this study are as follows: The degree of interest in appearance was identified with four factors; outfit management, confidence of figure, interest in clothing, weight control, and disinterest in appearance. Customers were segmented into two subdivisions: high and low interest in appearance. The factors derived from the factor analysis of underwear purchase motive included aesthetic, impulsiveness, and practicality. The purchase behavior of the group with high interest in appearance was highly motivated by aesthetics and impulsiveness. The factors derived from the factor analysis of underwear attitude included fashionability, comfortableness, and quality. Customers were segmented into the following three subdivisions: pursuit of comfortableness, pursuit of diversity, and normal. The type of high interest in appearance regarded fashionability and quality highly. Finally, the degree of interest in appearance showed significant relevance in purchase motive and underwear attitude for underwear.

  • As to the sphere of application, Article 78 CISG undoubtedly applies to interest on the purchase price. Furthermore, the provision also applies to "any other sum that is in arrears". This language has been interpreted to encompass expenses that one party had on behalf of the other as well as reimbursements when the purchase price is reduced according to Article 50 CISG. However, it is questionable whether this language also extends to claims for damages. Legal scholars seem to agree that one has a right to interest on damage claims under Article 78 if the amount in question has been liquidated vis-a-vis the other party. Whether this right to interest also applies to unliquidated sums, is controversial, however. In this study, as a result of taking into account the puspose of Article 78, we could find the fact that regardless of whether the exact amount of damages has been specified yet, the breaching party still owes compensation to the other party from the time of the breach and, accordingly, the non-breaching party should be entitled to interest payments on the loss from that time. Consequently, Article 78 applies not only to liquidated but also to unliquidated damages.

  • For a contract of insurance to be valid, the insured needs to have an insurable interest. This means that someone taking out insurance must stand to gain a benefit from the preservation of the subject matter of the insurance or to suffer a disadvantage should it be lost. Although the principle is simple, the detail is difficult. English Law Commission proposed some changes to provide certainty on the rule of insurable interest in LCCP 201. This article is, therefore, designed to examine the proposals for reforming trends in English insurance contract law. The proposals on Law Commission in summarized as following. First, LC proposed to retain the requirement for insurable interest because it was thought to fulfil four useful functions. Secondly, LC proposes to repeal the Marine Insurance Act 1788 and the Marine Insurance (Gambling Policies) Act 1909 to confirm that the requirement of insurable interest applies to all forms of insurance. Thirdly, LC proposes to retain the provisions on insurable interest in the Marine Insurance Act 1906. Finally, LC proposes to define insurable interest and thinks that full definition of insurable interest should remain flexible.

  • Community portraits can deeply explore the characteristics of community structures and describe the personalized knowledge needs of community users, which is of great practical significance for improving community recommendation services, as well as the accuracy of resource push. The current community portraits generally have the problems of weak perception of interest characteristics and low degree of integration of topic information. To resolve this problem, the reader community portrait method based on the thematic and timeliness characteristics of interest labels (UIT) is proposed. First, community opinion leaders are identified based on multi-feature calculations, and then the topic features of their texts are identified based on the LDA topic model. On this basis, a semantic mapping including "reader community-opinion leader-text content" was established. Second, the readers' interest similarity of the labels was dynamically updated, and two kinds of tag parameters were integrated, namely, the intensity of interest labels and the stability of interest labels. Finally, the similarity distance between the opinion leader and the topic of interest was calculated to obtain the dynamic interest set of the opinion leaders. Experimental analysis was conducted on real data from the Douban reading community. The experimental results show that the UIT has the highest average F value (0.551) compared to the state-of-the-art approaches, which indicates that the UIT has better performance in the smooth time dimension.
