인공지능 머신러닝을 활용한 가상현실 태권도 코칭 구조의 개발 방안
정자현,황원택,이형석 한국융합과학회 2022 한국융합과학회지 Vol.11 No.10
Purpose The purpose of this study is to investigate the development plan of virtual reality Taekwondo coaching structure using artificial intelligence machine learning Methods In order to achieve the purpose of this study, technology development was conducted by reviewing literature and collecting expert opinions. Result First, the functions that can participate in Taekwondo lectures were specifically implemented for each training subject. Second, differentiated and independent programs and functions were implemented for each training subject. Third, a gamification implementation structure was secured to improve the sustainability of training and programs. Conclusion The virtual reality taekwondo coaching structure using artificial intelligence machine learning was developed using smartphones and personal computers and prioritized that web safety and accessibility should be guaranteed. 연구목적 본 연구의 목적은 인공지능 머신러닝을 활용한 가상현실 태권도 코칭 구조의 개발 방안을 규명하는 것이다. 연구방법 선본 연구 목적을 달성하기 위해 문헌 고찰과 전문가 의견 수렴에 의한 기술 개발을 실시하였다. 결과 첫째, 수련 주체별로 태권도 강좌에 참여가능한 기능을 구체적으로 구현 하였다. 둘째, 수련 주체별로 차별화되고 독립적인 프로그램과 기능을 구현하였다. 셋째, 수련과 프로그램의 지속 가능성을 향샹 시키기 위해 게이미피케이션 구현 구조를 확보하였다. 결론 인공지능 머신러닝을 활용한 가상현실 태권도 코칭 구조는 스마트폰 및 개인용 컴퓨터를 활용하고 웹 안전성과 접급 가능성이 최상으로 보장 되어야 함을 우선시 하여 개발하였다.

목 적: 수면 문제는 지속적으로 성인의 자살 위험 요인으로 보고되어왔고 최근에는 청소년을 대상으로도 그 가능성이 보고되고 있다. 본 연구는 과거의 자살 행동 유무에 따라 대상군을 분류하여 이들 사이의 자살위험요인과 수면양상을 비교하고 자살위험요인으로써의 수면의 가능성을 평가해 보았다. 방 법: 고등학생 561명(남 271명, 여 290명)을 대상으로 자살위험행동 체크리스트, Center for Epidemiological Study-Depression(CES-D), Symptom Checklist-90-Revision(SCL-90-R) 불안, 공격성 하위척도, Pittsburg Sleep Quality Index(PSQI)가 시행되었다. 결 과: 46명(8.1%)이 자살시도 목적으로 자기 위해 행동을 한 경험이 있었고, 181명(32.4%)은 자살사고 경험만을 보고했다. 334명(59.5%)은 과거 자살위험행동(사고, 시도)을 보이지 않았다. 자살 위험군은 학교 폭력, 물질남용, 인터넷 중독, CES-D, SCL-90-R, PSQI에서 비자살 위험군에 비해 유의하게 점수가 높았다. 로지스틱 회귀분석의 결과 자살위험행동은 우울, 스트레스와 상관성을 보였고, PSQI에서는 수면 잠복기, 주간기능장애에서 상관성을 보였다. 일원분산분석(ANOVA, Analysis of variance)에서는 자살 시도군에서 수면 잠복기의 연장, PSQI 지수의 증가가 가장 심하게 관찰되었다. 결 론: 수면문제는 청소년군의 자살위험행동과 높은 연관성을 보인다. 특히 수면 잠복기, 주간기능장애가 자살위험행동의 중요한 인자일 것으로 여겨진다. 추후 부모, 교사, 의료인들에 의한 청소년의 수면에 대한 지속적인 평가와 관리를 권장하는 바이다. Objectives: Sleep problems has been consistently reported as a suicidal risk factor in adults and, recently, also in adolescents. In this study, dividing study subjects by the previous suicidal behaviors (suicidal vs non-suicidal), we compared the group differences of suicidal risk factors, and examined the possibility of sleep as a suicidal risk factor. Methods: Study subjects were 561 (271 boys and 290 girls) from a community sample of high school students. Suicidal Risk Behavior Checklist, Center for Epidemiological Study-Depression (CES-D), Symptom Checklist-90-Revision (SCL-90-R) Anxiety and Aggression subscale, Pittsburg Sleep Quality Index (PSQI) were done. Results: Forty six students (8.1%) reported previous actual self-harm behavior as a suicidal attempt, 181 students (32.4%) reported having suicidal thought only. Three hundred thirty four students (59.5%) reported no previous suicidal behavior (thought and attempt, both). Suicidal behavior group showed higher score on risk behaviors such as school violence, substance use and internet addiction. CES-D, SCL-90-R, PSQI showed significant group difference. Logistic regression analysis showed suicidal risk were significantly associated with depression, stress in suicidal risk factors and sleep latency, daytime dysfunction in PSQI. Analysis of variance (ANOVA) shows the most prolonged sleep latency and increased index of all PSQI components except sleep efficiency in suicidal attempt group. Conclusions: Sleep Problems had a strong association with the suicidal risk behavior in adolescents. Sleep problems, especially, prolonged sleep latency, daytime dysfunction might be important markers for suicidal behavior. Screening for sleep problems in adolescents are encouraged for the parents, school teachers, and related medical physicians.

Ministry of construction and transportation has been enforcing extensionally design phase VE(Value Engineering) to the construction costing more than 10 billion won, an importance of design phase VE accordingly is raising to get rid of a waste of cost and noneffective factors previously in construction projects. Although there are legal supports and technical effects, an effect about an introduction of design phase VE can not be applied properly because of several problems at the process. So, in this study, present competency evaluation checklist of design phase VE to highly raise the output through organizing an effective team at the beginning stage of design phase VE. Find out 29 competency factors through characteristics of design VE team for the checklist, classify by team knowledge, team work skill, and team attitude. Get an efficiency regarding importance and find out competency evaluation items of design VE team, present a competency evaluation checklist for indicating an objective standard to competency evaluation by measuring relative importance as to each competency evaluation item.

말기 위암 외래 환자에게 제공된 통증관리의 염려 및 주저정도에 미치는 효과
공성화,이상홍,정자현,김지영,이수연,김순애 임상간호사회 2004 임상간호연구 Vol.10 No.1
Purpose: This study was designed to evaluate the effect of cancer pain-management-education on the concerns and hesitancy of pain-management in out-patient of terminal gastric cancer. Method: 24 terminal gastric cancer patients who had not surgery, were assigned to the control group and 24 were assigned to the experimental group receiving pain-management-education. As Measurement-instrument of concern on pain-management and questionnaire on degrees of hesitancy were used the questionnaire developed by Ward( 1993) and translated by Kim Hong-Soo(1998). Data were analyzed per descriptive analysis, x²-test and t-test with the SPSS 10.0 program. Result: Degrees of concern of cancer-patient on pain-management between experimental-group and control-group showed significant difference: Experimental-group changed from 2.52 to 1.13 point(maximum 5 point) and control-group from 2.59 to 2.40 point(p=.000). Degrees of hesitancy of cancer-patient on pain-management between two groups showed significant difference. Experimental-group changed from 2.33 to 1.35 point and control-group from 2.77 to 2.52 point(p=.000). Conclusion: Above findings showed that pain-management-education reduces the concern and hesitancy on pain-management in out-patient of terminal gastric cancer. We conclude that the pain-management-education in this study was identified the effective nursing program.
