Purpose: A conflict of interest is defined broadly as a scenario in which one's responsibilities and self-interest collide in a manner that has a significant probability of corrupting one's discernments, motivations, actions, desires, values, and judgments. This study aims to investigate various cases of conflict of interest. Research design, data and methodology: Our study used the preferred reporting items for systematic reviews and meta-analyses (PRISMA) to identify resources. The eligibility of selected prior studies thoroughly was investigated whether they are suitable for the topic of present study. Finally, we collected total 15 previous studies published between 2000 and 2021. Results: Research findings indicate that there are three main cases that might cause a conflict of interest and mandated research ethics education might provide researchers with the tools to identify and battle the temptations and biases provided by conflicts of interest. Researchers could likely be better prepared for conflicts of interest if they investigated the moral difficulties associated with them in advance. Conclusions: Researchers might evade deliberate or unconscious detriment of duties, and also objectivity loss because of the siren song of self-interest by escaping situations whereby they may be tempted to shirk their responsibilities, not to remark the hassles of unveiling conflicts.

본 연구는 과학학업성취와 관련된 주요 정의적 변인들인 흥미, 자기조절능력, 과제집착력이 투지(Grit)와 어떤 구조적 관계를 보이는지를 탐색하고자 하였다. 고등학교 학생 180명(남학생 77명, 여학생 103명)이 투지, 흥미, 자기조절능력, 과제집착력과 과학학업성취(중간시험, 기말시험점수)를 조사하는 설문에 답하였다. 본 연구자들은 위 다섯 가지 요인들과 관련된 선행연구 고찰을 바탕으로 하여 두 개의 가설모형을 설정하였다. 하나의 가설모형에서는 투지가 흥미에 영향을 주고, 투지가 다시 자기조절능력과 과제집착력에 영향을 미치며, 이 후 자기조절능력과 과제집착력이 과학학업성취에 영향을 미치는 모형으로, 이모형에서는 흥미가 자기조절능력과 과제집착력에 간접적으로 영향을 주고, 그 사이를 투지가 매개하는 것으로 가정하였다. 이와 다른 모형에서는 투지와 흥미가 독립적인 요인으로 작용하여, 각각 자기조절능력과 과제집착력에 영향을 미치는 모형으로 가정하였다. 수집된 자료와 가설모형을 바탕으로 하여 요인간의 상관관계와 모형의 적합도 확인을 위해 구조방정식 분석을 실행하였다. 그 결과를 통해 학생들의 투지와 흥미는 독립적인 요인으로 작용하는 모형이 최적의 모형으로 선택되었다. 또한 과제집착력이 흥미와 자기조절능력과 깊은 상관관계를 나타내는 것을 확인할 수 있었으며, 본 연구에 참여한 남학생과 여학생 집단 간의 변인별 상관관계 비교를 통해 투지와 흥미, 과제집착력, 자기조절능력, 그리고 학업성취 간의 구조적 관계가 남학생과 여학생에게서 다르게 나타날 가능성이 있음을 확인하였다. 본 연구 결과를 통해 그동안 중요하게 연구되지 않았던 투지와 과제집착력과 같은 요인들에 대한 조사를 제안한다. 투지와 과제집착력에 대한 연구를 통해 학생들의 흥미가 감소하는 원인과 학생들이 어렸을 때 가졌던 과학에 대한 흥미를 유지하기 위한 방안을 탐색할 수 있으며, 과학학업성취와 관련된 다양한 정의적 요인들에 대해 조사하는 연구가 가능할 것으로 기대된다.

Nowadays with the help of Location-Based Social Networks (LBSNs), users of Point-of-Interest (POI) recommendation service in LBSNs are able to publish their geo-tagged information and physical locations in the form of sign-ups and share their experiences with friends on POI, which can help users to explore new areas and discover new points-of-interest, and promote advertisers to push mobile ads to target users. POI recommendation service in LBSNs is attracting more and more attention from all over the world. Due to the sparsity of users' activity history data set and the aggregation characteristics of sign-in area, conventional recommendation algorithms usually suffer from low accuracy. To address this problem, this paper proposes a new recommendation algorithm based on a novel Preference-Content-Region Model (PCRM). In this new algorithm, three kinds of information, that is, user's preferences, content of the Point-of-Interest and region of the user's activity are considered, helping users obtain ideal recommendation service everywhere. We demonstrate that our algorithm is more effective than existing algorithms through extensive experiments based on an open Eventbrite data set.

This study examines how the health of the banks in ASEAN-3 countries namely Indonesia, Malaysia and Thailand respond to the change in exchange rates and foreign interest rates in four large economies. The transmissions of the two external factors through domestic factors in each ASEAN-3 countries eventually affects Non-Performing Loan (NPL) of commercial banks. This study uses the monthly time series data and the renowned Structural Vector Autoregressive (VAR) model comprising five variables, namely exchange rate, foreign interest rate, domestic interest rate, money supply, and non-performing loan (NPL). The results indicate that there are different effects between ASEAN-3 countries, which can be classified as short-run effect and long-run effect. In the long run effect, external factors have a dominant role in determining NPL in ASEAN-3 countries. Yuan has the biggest effect on Malaysia's NPL, while Indonesia is more affected by European interest rates rather than the fluctuation of the US currency and China's interest rates. Among ASEAN-3 countries, Malaysia is the one that is the most vulnerable to external factors. While Thailand's NPL is affected dominantly by domestic factors. This study shows that the Fed Funds Rate (US official interest rate) is not always the dominant factor affecting the health of domestic banks in ASEAN-3.

The article considers online discussion as an interactive learning method in the conditions of distance learning. The essence of discussion and the stages of its organization are described. The main objective of discussion in distance learning is defined as the stimulation of interest in learning and the involvement of various viewpoints in an active discussion of the stated problems. The key role in ensuring the efficiency of a discussion is identified. The article develops a model for organizing asynchronous online discussions on the Moodle platform, highlighting the sequence of stages and their content. An experimental study of the use of the discussion method in the training of students in distance learning conditions is carried out. Based on the results of the methodological experiment, conclusions are drawn about student interest in online discussions. The authors conclude that the interest of students of different specialties in asynchronous online discussions varies, and the greatest interest is demonstrated by linguistics students. Nevertheless, the differences in student interest in online discussions by groups (specialties) are more likely attributable to subjective factors, which do not affect the overall picture in a major way.

Draper and Lawrence (1965a) have given mixture designs for three factors when all the mixture components can vary on the entire factor space so that the region of interest is an equilateral triangle in two dimensions. In this paper their work is extended to the cases when the region of interest is an echelon, parallelogram, pentagon or hexagon, because of the restirctions imposed on some or all of the mixture components. The principles used in the choice of appropriate designs are those originally introduced by Box and Draper(1959). It is assumed that a response surface equation of first order is fitted, but there is a possibility of bias error due to presence of second order terms in the true model. Minimum bias designs for several cases of restricted regions of interest are illustrated.

This study investigated consumer innovativeness by examining a relationship model of innate innovativeness, product interest, product-specific innovativenss, and actualized innovativeness for eight product items as well as observed gender differences in the variables. The eight product items for the survey were smartphones, movies, clothing, cars, skin care products/cosmetics, traveling, AI products, and books. An online survey was conducted in January 2018, and 400 responses from male and female consumers in their twenties and thirties, were analyzed using reliability test, descriptive statistics, regression, and ANCOVA. The positive effect of innate innovativeness and product interest on product-specific innovativeness, and positive effect of innate innovativeness and product-specific innovativeness on actualized innovativeness were confirmed. Product interest was found to have a stronger power on product-specific innovativeness than innate innovativeness. Gender differences in product interest, product-specific innovativeness, and actualized innovativeness were identified as hypothesized. Female consumer's clothing interest, clothing innovativenss, and actualized clothing innovativeness were higher than male consumers; in addition, male consumer's cars and AI interest, cars and AI innovativenss, and actualized cars and AI innovativeness were higher than female's. The controversial results that indicated the higher innate innovativeness of male consumers useful to further in-depth discussion and research. This study contributed to the theory construction of consumer innovativeness research areas and offered practical implications for new product launching and customer relationship management.

본 연구는 금리변동성이 금리수준과 양의 상관관계가 있음을 밝힘으로써 현행 위험기준 자기자본제도 하에서 금리리스크의 측정에 사용되는 금리변동계수가 금리수준에 따라 달라질 필요가 있음을 제시한다. 이를 위해 본 연구는 국공채 금리 자료를 이용, 이자율의 역사적 변동성을 측정하여 이자율 수준과 금리변동성 간의 비례관계를 확인한다. 또한 균형이자율 모형 중 지수형 Vasicek 모형과 Cox-Ingersoll-Ross 모형을 통해 금리수준과 금리변동성의 상관관계를 분석한다. 이후 국공채 자료에 기반하여 두 이자율 모형의 모수를 추정하고 이에 따라 금리수준별 금리변동성을 측정한다. 이에 따르면 금리수준이 높을수록 금리변동성 역시 크게 나타난다. 금리가 2.8%일 경우 지수형 Vasicek 모형과 CIR 모형에서는 금리변동계수가 각각 0.9와 1.1로 현 제도 하에서 금리하락 시 적용되는 금리변동계수 1.5보다 작게 나타난다. 이는 금리리스크에 대응하여 보험사가 보유해야 하는 자기자본이 현재 수준의 60%와 73% 로 낮춰질 수 있음을 의미한다. 본 연구에서는 이러한 결과를 반영하여 수정 금리변동계수를 이자율 모형에 따라 금리수준별로 제시한다. 금리수준과 금리변동계수를 연동시킴으로써 금리리스크를 보다 합리적으로 측정하고 관리하는 방안을 제시하였다는 점에 본 연구의 의의가 있다.

Interest is acknowledged to be a critical motivational variable that influences learning and achievement. The purpose of this study was to investigate the interest of the elementary students when free inquiry activities were performed through a brain-based evolutionary scientific teaching and learning model. For this study, 106 fifth grade students were chosen and performed individually free inquiry activities. The results of this study were as follows: First, after free inquiry activities, as to free inquiry science related attitude, a statistically significant difference was not observed. But they came to have positive feelings about the free inquiry. Especially students marked higher mean score in openness showed consistency in sub-areas of free inquiry science related attitude. Second, students had interests in various fields, especially they had many interests in area of biology. They chose inquiry subjects that seems to be easily accessible from surrounding and as an important criterion of free inquiry they thought the possibility that they could successfully perform it. And students who belong to the high level in the science related attitudes and academic achievement diversified more topics. Third, most of students failed to further their topics. However, the students who specifically and clearly extended their topics suggested appropriate variables in their topics. On the other hand, students who couldn't elaborate their topics were also failed to suggest further topics and their performance of inquiry was more incomplete. In conclusion, the experiences of success in free inquiry make the science attitude of students more positive and help them extend their inquiry. These results have fundamental implications for the authentic science inquiry in the elementary schools and for the further research.
