Objective: This study is to review three representative psychological perspectives that explain scientific construct of emotion, that are the discrete emotion model, appraisal model, and dimensional model. Background: To develop emotion sensitive interface is the fusion area of emotion and scientific technology, it is necessary to have a balanced mixture of both the scientific theory of emotion and practical engineering technology. Extensional theories of the emotional structure can provide engineers with relevant knowledge in functional application of the systems. Method: To achieve this purpose, firstly, literature review on the basic emotion model and the circuit model of discrete emotion model as well as representative theories was done. Secondly, review on the classical and modern theories of the appraisal model emphasizing cognitive appraisal in emotion provoking events was conducted. Lastly, a review on dimensional theories describing emotion by dimensions and representative theories was conducted. Results: The paper compared the three models based on the prime points of the each model. In addition, this paper also made a comment on a need for a comprehensive model an alternative to each model, which is componential model by Scherer(2001) describing numerous emotional aspects. Conclusion: However, this review suggests a need for an evolved comprehensive model taking consideration of social context effect and discrete neural circuit while pinpointing the limitation of componential model. Application: Insight obtained by extensive scientific research in human emotion can be valuable in development of emotion sensitive interface and emotion recognition technology.

Given the increasing information overload among users of online review websites, understanding the manner in which cognitive costs are reduced and efficient information is made reliable has become increasingly important. This study targets a unique consumer review design and explores how reviews from an external peer-to-peer site embedded in an online travel agency (OTA) website influence subsequent evaluation behaviors. The empirical results indicate that (1) embedded external reviews with a high average valence tend to strengthen the influence of the positive evaluation ratio while diminishing the effect of the review volume, and (2) embedded external reviews with a large variance strengthen the positive effect of the review volume while weakening the effect of the positive evaluation ratio on subsequent positive evaluations. The findings provide practical insights for consumers and online platforms.

개방형동료심사는 투고된 학술논문을 투명하게 심사할 목적으로 심사자의 신원, 심사의견, 심사결과를 저자를 포함한 일반 독자에게 공개하는 심사 방식이다. 개방형동료심사 인식에 관한 선행연구가 진행되었지만, 국내 과학기술 분야 학술지 편집담당자 관점에서 이러한 인식을 조사하고 분석한 연구는 찾아볼 수 없었다. 구체적으로, 학술지 편집위원의 개방형동료심사 적용 의향, 적용 시기 및 새로운 심사 방식을 채택할 때 예상되는 도전과 기회, 개방형동료심사 지원을 위한 투고심사시스템 요구사항에 관한 조사 및 분석은 부족한 실정이다. 이에 본 논문은 개방형동료심사에 대한 학술지 편집담당자의 인식을 조사하고 이러한 심사를 편리하게 지원하는 투고심사시스템의 핵심적인 요구사항을 이해하기 위해, 설문문항 준비, 설문조사 실시, 응답 결과를 분석하였다. 또한, 일부 과학기술 학술지 편집위원장을 대상으로 개방형동료심사에 관한 표적집단인터뷰를 수행하였다. 이후, 개방형동료심사 인식에 관한 본 연구의 분석 결과, 표적집단인터뷰 결과 및 국외 유사 설문조사 사례를 비교, 분석하고 시사점을 도출하였다. 본 연구 결과는 국내 학술단체에서 새로운 논문심사 방식의 정책 수립 및 시행, 투고심사시스템의 개방형동료심사를 위한 기능 탑재 및 선택 등의 의사결정에 도움이 될 것으로 기대된다.

With the development of sequencing technology, numerous, long noncoding RNAs (lncRNAs) have been discovered and annotated. Increasing evidence has shown that lncRNAs play an essential role in regulating many biological and pathological processes, especially in cancer. However, there have been few studies on the roles of lncRNAs in livestock production. In animal products, meat quality and lean percentage are vital economic traits closely related to adipose tissue deposition. However, adipose tissue accumulation is also a pivotal contributor to obesity, diabetes, atherosclerosis, and many other diseases, as demonstrated by human studies. In livestock production, the mechanism by which lncRNAs regulate adipose tissue deposition is still unclear. In addition, the phenomenon that different animal species have different adipose tissue accumulation abilities is not well understood. In this review, we summarize the characteristics of lncRNAs and their four functional archetypes and review the current knowledge about lncRNA functions in adipose tissue deposition in livestock species. This review could provide theoretical significance to explore the functional mechanisms of lncRNAs in adipose tissue accumulation in animals.

Peer review is a well-known, pervasive and most reliable method for assessment of research proposals. But with the strength of peer review, it also has some various limitations and shortcomings. This study suggests the use of bibliometric indicators as a counterbalance of shortcomings and mistakes in peer review. Bibliometric indicators suggested in this study are somewhat different from the conventional ones. Bibliometric indicators with limited number of papers, use of impact factor and discrimination first and corresponding authors from co-authors may produce a more resonable indicators. In this way bibliometric indicators can be considered as complementary to a peer review.

The constructability of formwork has a significantly influence on the duration and cost in tall building construction. However, current installation and dismantling process are conducted with heuristic approaches due to the absence of reasonable constructability review method. This study proposes a new method to review the constructability of formwork by utilizing 3D printing technology. It is expected that the suggested review method could reduce formwork duration and cost with subjective, but rational manner.
