Predicting the Currency Market in Online Gaming via Lexicon-Based Analysis on Its Online Forum
Kim, Young Bin,Kang, Kyeongpil,Choo, Jaegul,Kang, Shin Jin,Kim, TaeHyeong,Im, JaeHo,Kim, Jong-Hyun,Kim, Chang Hun Hindawi Limited 2017 Complexity Vol.2017 No.-
<P>Transactions involving virtual currencies are becoming increasingly common, including those in online games. In response, predicting the market price of a virtual currency is an important task for all involved, but it has not yet attracted much attention from researchers. This paper presents user opinions from online forums in a massive multiplayer online game (MMOG) setting widely used around the world. We propose a method for predicting the next-day rise and fall of the currency used in an MMOG environment. Based on analysis of online forum users’ opinions, we predict daily fluctuations in the price of a currency used in an MMOG setting. Focusing specifically on the World of Warcraft game, one of the most widely used MMOGs, we demonstrate the feasibility of predicting the fluctuation in value of virtual currencies used in this game community.</P>
Impact Analysis of Wind Farms in the Jeju Island Power System
Kim, Eel-Hwan,Kim, Jae-Hong,Kim, Se-Ho,Choi, Jaeho,Lee, Kwang Y.,Kim, Ho-Chan IEEE 2012 IEEE systems journal Vol.6 No.1
<P>This paper presents modeling and impact analysis of wind farms in Jeju island power system, which is made of wind farms, a current source-type high-voltage, direct current (HVDC) system, and thermal power plants. In this paper, four kinds of major components are modeled: a total of 88 MW wind farms, a 300 MW HVDC system, thermal power plants, and the Jeju power system load. To analyze the impact of the wind power generation to the Jeju power system, simulation is carried out for two case studies by using the PSCAD/EMTDC program. One is for the steady-state operation under different wind speed, and the other is for the transient-state operation when all wind farms are disconnected suddenly from the Jeju power grid due to the wind speed higher than the rated value. These comparative studies have been effective in accessing the impact of wind power generation on the Jeju island power system stability.</P>
Clinical significance of the lymph node ratio in N1 breast cancer

Purpose: The purpose of this study was to evaluate the prognostic value of the lymph node ratio (LNR), which was defined as the proportion of involved nodes of all dissected nodes, in pN1 breast cancer. Materials and Methods: We retrospectively analyzed the clinical data of patients with pN1 breast cancer (n = 144) treated at Keimyung University Dongsan Medical Center, Daegu, Korea between 2001 and 2010. The median age was 46 years (range, 27 to 66 years). The LNR was 0.01–0.15 (low LNR) in 130 patients and >0.15 (high LNR) in 14 patients. Sixty-five patients (45.1%) had T1 tumors, 74 (51.4%) had T2 tumors, and 5 (3.5%) had T3 tumors. Eighty-eight patients (61.1%) underwent total mastectomy and 56 (38.9%) underwent partial mastectomy. Fifty-nine patients (41.0%) underwent radiotherapy and 12 (8.3%) underwent regional radiotherapy. The median follow-up period was 65 months. Results: The 5- and 10-year disease-free survival (DFS) rates were 92.7% and 82.4%, respectively. Univariate analyses revealed that high LNR (p = 0.004), total mastectomy (p = 0.006), no local radiotherapy (p = 0.036), and stage T2 or T3 (p = 0.010) were associated with worse DFS. In multivariable analysis, only high LNR (p = 0.015) was associated with worse DFS. Conclusion: High LNR is an independent prognostic factor in pN1 breast cancer and could be an indication for adjuvant radiotherapy in these patients.
Correlation between balance and thickness of abdominal and quadriceps muscles

본 연구는 서 있는 자세에서 측정된 정적균형과 근육두께(배근육, 넙다리네갈래근)의 상관관계를 확인하였 다. 29명의 건강한 성인 29명이 본 연구에 참여하였으며, 근육두께와 정적균형을 측정하였다. 넙다리곧은근의 근 육 두께는 정적균형체중분포지수와 유의한 상관관계를 나타냈다. 그러나 다른 근육과의 유의한 관계는 발견되지 않았다. 본 연구는 건강한 20대 남성만을 대상으로 하였으며, 그 결과를 다른 연령대에 일반화할 수 없었다. 본 연구의 한계점으로는 근력과 시각이 측정되지 않아 연구의 정확성을 표현하고 결과를 일반화하기에는 무리가 있어 보인다. 향후 연구에서는 대단위의 피험자 수를 대상으로 근력을 추가적으로 측정하여 연구를 진행할 필요가 있다. This study compares the correlation between muscle thickness (abdominal, quadriceps muscle) and how the muscle thickness affects the static balance when the static balance is measured in a standing position. The subjects of study were to select 29 subjects to find out what relationship muscle thickness had on the static balance when measuring muscle thickness and static balance. rectus femoris muscle thickness showed a significant correlation in statically balanced weight distribution index. In this study, only healthy men in their twenties were selected, and the results could not be generalized to other age groups. As a limitation of this study, muscle strength and peripheral vision were not measured, so it seems difficult to express the accuracy of the study and generalize the results. In future studies, the number of subjects and muscle strength should be measured to proceed with the study.
