초등학생들의 게임요소에 대한 선호도와 게임 중독과의 상관관계 연구
심정우,이재무 한국게임학회 2009 한국게임학회 논문지 Vol.9 No.2
본 연구는 초등학생들의 게임요소에 대한 선호도와 게임의 중독성과의 상관관계를 밝히는 것이다. 현재 초등학생들에게 있어 게임 중독은 심각한 상황에 이르고 있다. 그러나 게임요소에 대한 초등학생의 선호도를 구체적으로 분석한 연구와 게임요소와 게임중독과의 관계를 분석한 연구는 거의 없다. 그러므로 본 연구의 목적은 게임 중독과 관련된 게임 요소의 상관관계를 밝혀 게임 중독을 예방하고자 한다. 연구 결과 감각적 욕구충족, 지적욕구충족, 현실이탈 욕구충족, 경쟁 욕구충족, 사회적 욕구충족 등 측정한 모든 게임요소에 대한 선호도가 남학생이 여학생보다 유의하게 높았고, 게임을 선호하는 학생이 게임을 선호하지 않는 학생에 비해 높았다. 사회적 욕구충족에 대한 선호도는 학업성적이 낮을수록 높았으며, 감각적 욕구충족과 지적 욕구충족에 대한 선호도는 RTS 게임을 선호하는 학생이 가장 높았고, 레이싱과 액션게임을 선호하는 학생의 선호도가 가장 낮았다. The purpose of this study is to clarify correlation between preference for game element and game addiction in elementary-school students. In the current elementary-school students, the game addiction is reaching the serious situation. However, there are almost no research that specifically inquired into preference for game element in elementary-school students, and research that inquired into relationship between game element and game addiction. Therefore, this study aims to prevent game addiction by clarifying correlation between the addiction to game and the relevant game element. As a result of researching, the preference for game element was significantly higher in male students than in female students. And, the students of preferring a game were higher compared to the students of not preferring a game. The preference for the social desire satisfaction was higher in the lower academic achievements. The preference for the sensible desire satisfaction and for the intellectual desire satisfaction was the highest in students of preferring RTS game. And, the preference in students of preferring racing and action game was the lowest.

Purpose: This study was performed to evaluate the effect of the implant recipient site preparation methods on primary stability of implants with the instruments of $Osstell^{TM}$ and $Periotest^{(R)}$ in the iliac bone of cadaver. Methods and materials: The 8 iliac bones in 4 cadavers and implants treated with resorbable blasting media (RBM) were used. $Periotest^{(R)}$ (Simens AG, Germany) and $Osstell^{TM}$ (Model 6 Resonance Frequency Analyser: Integration Diagnostics Ltd., Sweden) were used to measure primary stability of implants. Implants were inserted into the iliac crest of the cadaver. In control group, the recipient site was prepared according to the manufacturer's recommendation: 1.8 mm guide drill, 2.0 mm initial drill, 2.7 mm pilot drill, 2.7 mm twist drill, 3.0 mm twist drill, 3.3 mm pilot drill, 3.3 mm twist drill, and 3.3 mm countersink drill as well as tapping drill were used in order. In the group 1, implant recipient sites were prepared by sequentially drilling from 1.8 mm guide drill to 3.0 mm twist drill and then inserted implants without countersinking and tapping. In the group 2, implant recipient sites were prepared to 3.0 mm twist drill and countersink drill and then inserted implants without tapping. In the group 3, the sites were prepared to 3.0 mm twist drill and countersink drill as well as tapping drill. In the group 4, the sites were prepared to 3.3 mm twist drill. In the group 5, the sites were prepared to 3.3 mm twist drill and countersink drill. A total of 60 implants were placed (n=10). The stability was measured using $Osstell^{TM}$ and $Periotest^{(R)}$ mesiodistally and buccolingually. To compare the mean stability of each group statistically, One-way ANOVA was used and correlation of instrument were analyzed using SPSS 12.0. The results obtained were as follows; 1. The stability of group 1 measured using $Osstell^{TM}$ and $Periotest^{(R)}$ buccolingually showed the highest, and there are significant difference statistically between control group and experimental group 1,2,4 in each instruments respectively (p<0.05). 2. The stability of group 1 measured using $Osstell^{TM}$ and $Periotest^{(R)}$ mesiodistally showed the highest. There are significant difference statistically between control group and all experimental groups in $Osstell^{TM}$, and between control group and experimental group 1,2,3,4 (p<0.05). 3. There are high correlation between the measurements of $Osstell^{TM}$ and $Periotest^{(R)}$ (p<0.05). Conclusion: These results indicate that the primary stability of implant can be obtained by the recipient sites preparation with smaller diameter drill than that of implant or minimal drilling.
아급성 뇌졸중 환자에게 무릎 신전 보조기기가 균형과 보행에 미치는 효과 및 유용성 : 사례 연구

Background: This study was to confirm the effect and feasibility of knee extension assist orthosis (KEAO) on balance and gait in subacute stroke patients. Design: Case study. Methods: The subjects of the study were 4 subacute stroke patients, who had an onset period of less than 6 months. The limit of stability (LOS) and berg balance scale (BBS), timed up and go test (TUG) were used to verify the dynamic balance ability, static balance ability, and gait ability pre and post and after wearing the knee extension assist orthosis (KEAO). In addition, the satisfaction survey was to confirm the feasibility of the knee extension assist orthosis (KEAO) through the to Korean quebec user evaluation of satisfaction assistive technology 2.0 (K-QUEST 2.0). Results: After the wearing on KEAO, the distance for the limit of stability decreased by mean 541.25±240.46 mm2, and the score on the berg balance scale improved by mean 5±2.71 point, and the time for the timed up and go test deceased by mean 3.75±1.71 second. The stability and durability were found to be full score, and the control, ease, effectiveness were some high score, and the size, weight, comfort were some low score in the satisfaction and feasibility. Conclusion: The knee extension assist orthosis (KEAO) produce in this study was improved the static balance ability, dynamic balance ability and gait ability of subacute stroke patients, and the satisfaction and feasibility were high in the stability, durability and effectiveness of the user.

심정우,이상민,김나래,장영우,Yon Mi Sung,김준환 고신대학교(의대) 고신대학교 의과대학 학술지 2018 고신대학교 의과대학 학술지 Vol.33 No.2
Tracheobronchopathia osteoplastica (TO) is a rare benign disease in which the anterior inner wall of the tracheobronchus changes because of abnormal chondrogenesis or ossification, while the posterior wall of the trachea is spared. The etiology is not clearly understood, but may relate with chronic infection, inflammation, and trauma. In some case studies, it has also been reported to be accompanied by other chronic diseases such as atrophic rhinitis and amyloidosis. However, Coexistence of TO and tuberculosis has rarely been reported, and has never been reported in Korea. Here, we report a case of a 70-year-old male patient who complained of hemoptysis and whose case was diagnosed as TO and pulmonary tuberculosis through bronchoscopy with bronchial washing and biopsy.
