Communication skills are emphasized as one of the key competencies of the people who are living in the fourth industrial revolution era. However, it is widely believed that traditional education systems focused on individual learning do not provide sufficient communication opportunities. This paper proposes a method to activate communication using mobile app. In this study, 〈Everybody’s Neighbor〉 app was developed and used by college students for two days, and then analyzed the communication-related effects through questionnaires. The results showed that both fun and communication were effective. Based on the experimental results, it is expected that the proposed app in this paper will contribute to activation of communication among people, increase of interest among members, and improvement of cooperative thinking ability.

Aims: Baveno VI and extended Baveno VI criteria have been proposed to avoid screening endoscopies. However, this approach has not been validated in the diagnostic performance of shear wave elastography (SWE). In this study, we aimed to validate these criteria in patients with SWE, also considering potential differences in predictable value with transient elastograpy (TE) and SWE. Methods: We evaluated in 526 patients with compensated advanced chronic liver disease (cACLD) was defined by liver stiffness (LS) measurement ≥10kPa, Child-Pugh class A and no prior liver decompensation. LS was obtained by TE (FibroScan, Echosense) or 2D-SWE (APLIO 500, Toshiba). Baveno VI (LS< 20 and PLT >150,000) and extended Baveno VI (LSM< 25 and PLT >110,000) criteria were tested. Results: Any grade EV were found in 22.2% of the patients with cACLD, while VNT in 18.6%. Two hundred sixty-two patients had LSM by TE, 305 patients by 2D-SWE. In the subgroup of 262 patients with TE, Baveno VI and Baveno VI extended criteria spared 21.6% and 37.1% of endoscopy, missing 7.1% and 12.5% of VNT, respectively. We identified as the best thresholds for rule-out presence of EV, LSM<23.3 kPa and high risk EV, LSM<25.2 kPa for TE. In the subgroup of 305 patients with 2D-SWE, Baveno VI and Baveno VI extended criteria spared 38.7% and 60.0% of endoscopy, missing 5.9% and 9.8% of VNT, reflecting better diagnostic performance than TE. In this subgroup for SWE, we identified as the best thresholds for rule-out presence of EV, LSM<16.5 kPa and high risk EV, LSM<17.2 kPa. For predicting EV, AUROC of SWE was higher than that of TE (0.791 vs. 0.744). Conclusions: The Baveno VI and Baveno VI extended criteria with 2D-SWE spare more endoscopies than with TE with a minimal risk of missing VNT in patients with cACLD.

Aims: There is considerable interest in developing non-invasive models to predict the presence of varices. Liver and spleen stiffness measured by 2dimensional shear-wave elastography (2D-SWE) have become Methods: of interest with good reliability in detecting portal hypertension. In this regard, measurement of the spleen stiffness reflects more accurately the dynamic changes occurring in advanced stages of cirrhosis compared to liver stiffness. We investigated the feasibility of liver- and spleen-SWE for diagnosis of esophageal varices (EV) and detection of high-risk varices. Methods: A total of 191 cirrhotic patients who underwent liver stiffness, spleen stiffness measurements, using 2D-SWE (APLIO 500, Toshiba), along with endoscopic screening were included in this study. Large EV (F2 or F3) or F1 with red colour sign were defined as high-risk EV. Results: EV was present in 130 patients (68.1%). For the presence of EV, the stiffness in liver-SWE had better diagnostic accuracy than the stiffness in spleen-SWE (the area under the receiver-operating characteristic curve (AUC), 0.830 vs. 0.740; Delong test, P=0.050). The best cut-off values in detecting of EV were 14.1kPa: liver-SWE and 16.5kPa: spleen-SWE. Increasing stiffness in spleen-SWE was proportionally correlated with grade of EV, whereas the stiffness in liver-SWE was not. For the presence of high-risk EV, the AUC in spleen-SWE was higher than liver-SWE (0.764 vs. 0.742), but not significantly different. Then, the strongest association was found between high-risk EV and spleen-SWE (r=0.397, P<0.001), with the next strongest association found for Child-Turcotte-Pugh score (r=0.353, P<0.001) and liver-SWE (r=0.314, P<0.001). The best cut-off values for predicting high-risk EV were 14.3kPa: liver-SWE and 22.1kPa: spleen-SWE. Conclusions: In patients with cirrhosis, stiffness measurements obtained by using 2D-SWE have effective non-invasive method for detection of EV. Moreover, the stiffness in spleen-SWE might be a better diagnostic value than liver-SWE for high-risk EV that requires prophylactic therapy.
2030세대 개인투자자의 감정적인 투자를 예방하기 위한 컴패니언쉽과 리추얼 요소 기반의 금융 챗봇 인터랙션 디자인 연구

주식투자에 익숙하지 않은 초보 투자자들은 투자원칙의 부재 및 경험 부족으로 감정적인 투자 의사결정을 하기 쉽다. 또한 투자결과에 대해 민감하게 반응하여 향후 공격적인 투자를 집행하는 등 비합리적인 의사결정을 내리기도 한다. 이러한 심리적 편향을 예방하며 주식투자자들이 이성적인 판단을 하기 위해서는 지속적인 경험과 복기를 통해서 본인의 투자행동을 정교화시키는 것이 중요하다. 따라서 본 연구에서는 주식투자 복기를 도와주는 챗봇을 기획하고, 이에 대한 효과성을 알아보고자 했다. 또한 컴패니언쉽 요소(컴패니언쉽 유/컴패니언쉽 무)와 리추얼 요소(리추얼 유/리추얼 무)를 독립변수로 2X2 집단 간 실험을 수행하였다. 연구 결과, 세 가지 종속변수에 대해 컴패니언쉽 요소(컴패니언쉽 유/컴패니언쉽 무)의 주효과는 나타났지만, 리추얼 요소(리추얼 유/리추얼 무)에 따른 주효과는 나타나지 않았다. 또한 컴패니언쉽 요소과 리추얼 요소 간 상호작용 효과도 발견되지 않았다. 구체적으로, 컴패니언쉽을 가지고, 개별 특성에 대한 정보를 적극적으로 수집하고, 친근한 말투와 매너로 과업을 함께 수행했던 에이전트는 그렇지 않았던 에이전트에 비해 투자 결과에 대한 부정적인 감정 완화, 자기통제감 및 유저 관여도 강화 등에 더 높은 효과를 보이는 것으로 나타났다. 이 결과는 개별 사용자의 주관적 특성을 반영한 자산관리 챗봇 에이전트를 설계할 때에 컴패니언쉽과 같은 챗봇의 사회적 요소를 적극적으로 고려해야 한다는 점을 시사한다. 한편, 리추얼의 실용적 적용의 한계 등에 대한 추가적인 연구가 필요하다. Beginner investors who are not familiar with stock investment are apt to make emotional investment decisions due to lack of investment principles and lack of experience. They also make irrational decisions by reacting sensitively to investment results and executing aggressive investments in the future. In order to prevent this psychological bias and to make rational decisions for stock investors, it is important to refine their investment behavior through continuous experience and refinement. Therefore, in this study, we conducted experiment of 2X2 between subject design with two Independent variables(partnership, ritual). The study found the main effect on the partnership elements for three dependent variables. However, no main effects were found on the ritual elements. In addition, no interaction effects were found between the partnership and ritual elements. The results suggest that the social factors of chatbot, such as partnerships, should be actively considered when designing chatbot agents that reflect the subjective characteristics of individual users. On the other hand, further research is needed on the limitations of the practical application of the ritual element.

This study investigates how particular configurations of conditions successfully resulted in peace building for 22 post-conflict countries during the period of 1965-1997. In particular, the paper focuses on whether democratic accountability, GDP per capita, intervention of UN PKO, and quality of government are important conditions that are associated with the successful peace building two to five years after the civil war, for post-conflict countries. Using the crisp-set analysis, this paper examines how the combination of these four conditions contributed to the successful peace building. The results suggests that a high quality government with the absence of UN PKO’s intervention two years after the war, and a high quality of government in combination with both high level of democratic accountability and high level of GDP per capita five years after the war, both attribute to the successful peace building. This paper highlights not only the importance of a good quality government but its configuration to the other three conditions that allows for successful peace building.
