Balance is a complex motor skill that depends on interactions between multiple sensorimotor processes and environmental and functional contexts. Many rehabilitation specialists believe that balance assessment under multitask conditions may be a more sensitive indicator of balance problems and falls than balance assessment in a single-task context. Functional Gait Assessment has many tasks that allow for testing under multitask conditions. The purpose of this study was to determine the concurrent validity between the Functional Gait Assessment (FGA), Berg Balance Scale (BBS), and Timed "Up & Go" Test (TUG) in patients with stroke. One hundred and five participants with at least 3 months post stroke and able to walk at least 6 m with or without a mono cane, participated in this study. Concurrent validity between the FGA, BBS, and TUG was assessed using Spearman rank order correlation. The FGA correlated with the BBS (r=.80, p<.01) and TUG (r=-.77, p<.01). The good and moderate correlation between the FGA, BBS, and TUG establishes the concurrent validity of the FGA in patients with stroke. These measures provide clinicians with valuable information about patients' functional balance capabilities.

바둑에 있어 사활 문제는 컴퓨터 바둑을 구현하기 위하여 반드시 극복되어져야 하는 기본적인 문제이다. 사활 문제와 같은 국부적인 문제를 풀기 위하여, 중요하게 고려되어야 할 사항은 어떻게 하면 게임 트리의 분기수와 그 깊이를 줄일 수 있느냐는 것이다. 본 논문에서는 게임 트리를 위한 첫 수들을 생성하기 위하여 휴리스틱 세력 함수로 눈 모양 분석이라는 초유의 방법을 적용하였다. 휴리스틱 세력 함수로 둘러싸인 돌들의 눈 모양을 분석하는 주요 목적은 아주 짧은 시간내에 둘러싸인 돌들이 살았는지, 미생(未生)인지 아니면 죽었는지를 판단하는 것이다. 만약 둘러싸인 돌들이 죽거나 미생일 경우가 높으면, 완전 게임 트리 내에서 최선의 수순을 찾아내기 위해 소요되는 엄청난 계산 시간을 절약할 수 있는 가능한 급소 점(첫 수)들로 사용될 수가 있다. 비록 눈 모양 분석기는 40% 미만의 정확도를 보였지만, 단순한 휴리스틱 세력함수로 된 눈 모양 분석기는 짧은 시간 내에 둘러싸인 돌들의 생사 여부를 판단하는 데 상당한 도움이 됨을 발견했다.

Most of the studies on Confucian Architecture dealt with the administrative system and typification. The study was about the outline buildings of the Architecture. However, specific view of personal architecture is limited. The aim of this study is to clarify the idea of Seonbi, Confucian Scholars in Choson Dynasty, in building the second house, Byul-Seo Architecture. The Byul-Seo was used to Jang-Su(藏修) for training oneself and teaching his students, and You-Sik(遊息) for strolling the surrounding of nature. The Byel-Seo in Bogil-do by Gosan Yoon, Sun-Do is influenced not only by the idea of Confucianism which is 'knowing through by approaching to object(格物致知)', but also by Feng-shui and Taoism. From the idea of Gosan Yoon, Sun-Do in Byul-Seo Architecture, ecology and spirit of the times must applied to our modern architecture.

This study aims to compare the relationship between the Berg Balance Scale (BBS) scores, Timed Up & Go (TUG), Functional Independent Measure (FIM), and subject characteristics. All of the 18 subjects were women between the ages of 68 and 91 (mean=80.2, SD=5.43), and they all lived at the nursing home in Wonju. Balance was measured using BBS, and functional mobility was measured using TUG. FIM was used to evaluate functional independence. Data were analyzed using Spearman correlation. Statistically significant differences were noted between BBS and TUG (r=-.486, p<.05). There were no significant statistical differences between total FIM and BBS, TUG. The FIM items "locomotion" and "communication" showed significant statistical differences between BBS and TUG. The results suggest that FIM may be able to predict dangerous falls in elderly people.

The purposes of this study were to find correlations among Fugl-Meyer Assessment scale, gait speed, and Timed Up & Go test (TUG) and to predict gait ability from subscales of Fugl-Meyer Assessment scale. The study population consisted of 30 stroke patients referred to the Department of Rehabilitation Medicine in the Bundang Jaesang General Hospital. All subjects were ambulatory with or without an assistive device. All participants were assessed on Fugl-Meyer Assessment scale and gait speed (m/s), TUG (s). The data were analyzed using independent t-test, Pearson product moment correlation analysis and stepwise multiple regression. The results revealed that all items of Fugl-Meyer Assessment scale, except passive joint range of motion were significantly correlated with gait speed and TUG. In particular, sensation score, lower extremity motor and coordination score have a significant correlation with gait speed and TUG (p<.05). The sensation score and lower extremity motor score were important factors in comfortable gait and maximal gait speed. Their power of explanation regarding comfortable gait and maximal gait speed were 63.0% and 65.0%, respectively. The sensation score and lower extremity coordination score were important factors in TUG. Their power of explanation regarding TUG was 55.0%. These results showed that Fugl-Meyer Assessment scale is significantly correlated with gait speed and TUG. Therefore Fugl-Meyer Assessment scale is an appropriate assessment tool to predict gait ability of patients with stroke. Further study about gait speed and TUG by change of Fugl-Meyer Assessment score is needed using a longitudinal study design.

To evaluate the effect of Jingansikpungtang water extract on cultured mouse spinal sensory neuron which was inhibited by glucose oxidase(GO)-induced cytotoxicity, NR assay and TBARS assay for lipid peroxidation were carried out after the cultured mouse spinal sensory neuron were pre-incubated with various concentrations of Jingansikpungtang water extract for 3 hours prior to exposure of GO. GO, a oxygen radical, decreased the survival rate of the cultured mouse spinal sensory neuron cells on NR assay. Jingansikpungtang water extract have efficacy of decreasing lipid peroxidation increasing by GO in cultured mouse spinal sensory neuron. From above the results, it is concluded that Jingansikpungtang has marked efficacy as a treatment for the damages caused in the GO-mediated oxidative process..

This paper investigates into a lost koˇmun'go tablature attributed to Soˇnghyoˇn callcd hyoˇnguˇmhapjabo[現金合字譜]. based on evidence drawn from hyoˇnguˇmhapjaboso written by the same author. Up to the present, the historical value of hyoˇnguˇmhapjabo[現金合字譜] has been largely overlooked by most Korean scholars. However, an introduction to this document provides important insights into the state of koˇmun'go music during the 15-16th century. Besides, the koˇmun'go tablatures from 16-17 centuries indicate that even prior to Kumhapjabo. the earlist extant koˇmun'go tablature. there was another notational system for the instrument and that Soˇnghyoˇn was possibly the editor. This allows present-day scholars to make some conjectures regarding the possible nature of the lost noation. This study, after examining the various writings of soˇnghyoˇn and other 16-17th-century sources, reconstructs the background and the contents of hyoˇnguˇmhapjabo. With the aid of his brother, a connoisseur of music. Soˇnghyoˇn. was able to learn the arts of koˇmun'go from the contemporary master Yi Ma-ji(이마지). After this initial contact, soˇnghyoˇndvoted his to music. occasionally learning from and exchanging artistic ideas with masters like Yi Ma-ji. Kim Pok-kuˇn (金福根). and Choˇng Ok-kyoˇng(鄭玉京). From as early as 25 years of age. Soˇnghyoˇn was reknowned as an authority in music, which led him to hold an important position at the Changakwon. after being appointed a goverment official. It was during this period that soˇnghyoˇn was exposed to Chong In-ji's influence and his important book Yulnyo-sinso(律呂新書). which further expanded his knowledge in music. Such a long period of accumulating knowledge in koˇmun'go music foregrounded soˇnghyoˇn's invention of a koˇmun'go notational system and his publication of hy on gu mhapjabo. Therefore one can safely conclude that his work epitomizes his in-depth understanding of the koˇmun'go tradition and that he intarded it as a solution to his life-time concern that the traditions of koˇmun'go master were dring without being faithfully transmitted. The tablature was intended to serve the needs of students who learned koˇmun'go without neccedssarily having a teacher to guide every step. The actual content of hyoˇnguˇmhapjabo is surmised to have been comprisad of yoˇmilnak, pohoˇja, kamgun'un, halnimbolgok. Taeyoˇp. and pukjoˇn The introduction to kuˇmhapjabo states that there was already a tablature before the mid 16th century. with a rather inconsistent notationa system and that kumhapjabo is merely a re working of that prototype with the addition of a few new pieces. This points to the possibility that the system at issue is actually S oˇ nghyoˇ's hyoˇng uˇmhapjabo, of which kuˇmhapjabo is simply a revision. There soˇnghyoˇn's hyoˇnguˇmhabjabo, although lost, bears the historcal significance of having been the very first koˇmun'go tablature ever written in the hapjabo notational system. Further, the existence of an earlier tablature than Kuˇmhapjabo(琴合字譜) may help explain the structure of the pieces contained in kuˇ mhapjabo that are presumed to have had a longer history.

간단한 규칙에도 불구하고 바둑은 인공지능 분야에서 가장 복잡한 전략적 보드게임 중의 하나이다. 몬테카를로 트리탐색(MCTS)은 최상우선 트리탐색 알고리즘으로 컴퓨터바둑 제작을 위해 사용되어 왔다. 저자는 9줄바둑판보다 작은 바둑판에서의 바둑게임 행위를 위해 MCTS를 활용하여 가장 유망한 첫 수를 찾고자 한다. 실험결과에 의하면 MCTS는 첫 수로 홀수형 바둑 판에서는 정중앙, 짝수형 바둑판에서는 중앙 부근에 착수하기를 선호하는 것으로 나타났다.

바둑은 최상의 착점을 찾기 위해 컴퓨터가 완전탐색을 하여 모든 가능한 착점들을 탐색할 수 없는 가장 복잡한 보드게임이다. AlphaGo 이전에 모든 강력한 컴퓨터바둑 프로그램들은 게임트리 내 매우 큰 분기수와 국면평가에서의 어려움을 극복하기 위해 몬테카를로 트리탐색(Monte-Carlo Tree Search)을 사용해 왔다. 본 논문에서는 MCTS를 활용하여 초소형 바둑에서의 최상의 수순과 덤의 크기를 알고자 했다. 2줄바둑에서의 게임결과는 빅이 되었으며 덤의 크기는 0집, 반면에 3줄바둑에서는 흑이 항상 승리하고 덤의 크기는 9집이 되어야 함을 알아냈다.

In 21 st Century business world, services are carried out in multifaceted, competitive and rationality manner that are characterized by evolving many factors, which are often unpredictable. On-the-go banking is a product in financial sector. However, it faces serious pitfalls being it riskiness. Bank customers compete for time-saving options. On contrary, PCBs compete for marginalizing its operating costs for enhancing its revenues. On strategic tactics, PCBs targets city customers in multi-facets including offering incentives for enhanced usages of on-the-go banking. Influencing customer’s intention, attitude and behavior in banking, PCBs also offers incentive under market system along with often informational asymmetry. However, it causes exploitation. In most cases customers don’t read terms & conditions of services. They don’t save contract-copy. These weaknesses cause abuses. Customer faces hidden charges, extra fees, account hacked. Addressing the issue, Voluntary Insurance Option is proposed where PCBs will introduce it as a product of bank-services. Transferring risk away from customer will benefit both PCBs and bank-customers. This product can attract new customers who were on the brink using digital banking but just felt it was too risky. This model can facilitate the parties involved for increasing usage of on-the-go banking-services while customers can maintain optimal utility of usages.

본 연구는 ‘포켓몬 고’ 게임 상품을 경험한 사용자들의 증강현실 게임속성이 사용자 태도와 여가만족에 미치는 영향을 파악 하고, 게임 속성과 사용자 태도 간에 어떤 관계 또한 게임속성과 여가만족, 그리고 게임속성과 여가만족간의 사용자 태도의 매개효과를 검증하는 실증분석 연구이다. 먼저, 문헌연구를 통해 증강현실 게임 속성으로 오락성, 도전성, 상호작용성, 현 실성 네 가지를 도출하였다. 표본은 포켓몬 고 게임 상품을 이용한 사용자들을 대상으로 설문조사를 실시하였고 그 결과를 분석한 것이다. 실증분석 결과 포켓몬 고 게임 상품 속성과 여가만족 사이에 유의한 상관관계가 있는 것으로 나타났으며, 사용자 태도의 매개효과 분석에서도 유의한 영향을 미치는 것으로 분석되었다. 특히, 기존 선행연구에서는 온라인 게임의 상호작용성이 유의함이 좀 더 높게 나타났으나 본 연구에서는 오락성과 상호작용성 그리고 현실감이 유의하게 나타나 여가 만족에 영향을 미친다고 할 수 있겠다. 따라서 새롭게 출시된 증강현실 기반 게임 ‘포켓몬 고‘도 다양한 여가생활의 한 종 류로서 긍정적인 인식을 갖게 되는 기회가 되기를 바라며, 증강현실 기반 게임이 여가생활에 있어 여가만족에 기여할 수 있는 부분임을 확인할 수 있는 학문적 실증분석 연구이다.

인공지능 연구에서 바둑은 위치평가의 어려움과 엄청난 분기수로 인해 가장 도전적인 보드게 임으로 여겨지고 있다. 몬테카를로 트리탐색은 이러한 문제점을 극복할 수 있는 고무적인 돌파 구이다. 알파고의 숨겨진 아이디어는 주어진 위치에서의 승률을 예상하여 깊은 탐색을 유도한 후 가장 고무적인 착수를 찾아내는 것이었다. 본 논문에서는 무전략 MCTS를 활용하여 9줄바 둑에서 프로기사들이 최상의 첫수로 여기는 천원점이 옳다는 것을 확인했으며, 또한 가장 유행 하는 첫 수들의 평균승률을 비교했다.
