  • 신체의 감각기관 중에서도 손가락의 운동과 감각 부분이 뇌에 가장 큰 영향을 미친다는 것은 널리 알려진 사실이다. 본 연구는 이러한 사실에 주목하여 교육, 훈련, 건강증진 등의 목적으로 다양하게 활용이 가능한 기능성 게임 장치를 개발하되, 주로 두뇌향상을 위한 다섯 손가락의 균형적 사용에 초점을 맞춘 게임 콘텐츠를 위한 장치 개발하고자 한다. 제안하고 있는 게임 장치는 본체 부분만을 독립적으로 사용하는 '오프라인' 방식과 스마트폰 등의 단말기와 연동하여 사용하는 '온라인' 방식의 2가지 방식으로 게임을 즐길 수 있다. '온라인' 방식으로 동작할 때는 블루투스를 통해서 연동되는 단말기에서 시각 정보를 표시하여 게임을 진행하는 것이 가능하고 '오프라인' 방식에서는 주로 청각과 촉각 등을 이용하여 두뇌 훈련을 하거나 정서를 함양하도록 고안되었다. 본 게임장치의 성능과 활용 가능성을 살펴보기 위해서, 연령에 관계없이 모두가 즐길 수 있는 온라인 모드의 슈팅게임과 촉각이나 청각에 의존하는 고령자 친화형 게임콘텐츠인 낚시게임을 개발하였다. 낚시 게임은 온라인 모드로 게임을 진행하는 것도 가능하지만 오프라인 모드에서는 청각과 순발력을 이용하여 다섯 손가락을 균형 있게 사용하게 함으로써 뇌활동이 저하되는 고령자가 게임을 통해 치매, 기억력 저하 등의 인지기능 장애를 예방하는데 도움을 줄 수 있다.

  • Background: The purpose of this study was to determine the effect of Postural Yinyang correction of the temporomandibular joint (functional cerebrospinal therapy) on temporomandibular disorder. Methods: Medical records of 21 outpatients were reviewed who were diagnosed with temporomandibular joint disorder, unspecified (K0769) and treated at the Department of Acupuncture & Moxibustion, Dong-Eui University Korean Medicine Hospital from May $1^{st}$, 2017 to April $30^{th}$, 2018. Patients received more than 10 treatments of upper cervical manipulation and performed self-exercise therapy more than 3 times a day and wore an accurate balancing appliance in the oral cavity for more than 8 hours per day. To estimate the efficacy, visual analogue scale (VAS), numerical rating scale (NRS), maximum mouth opening (MMO), symptom intensity scale (SIS), max SIS (MSIS), symptom frequency scale (SFS), mandibular function impairment questionnaire (MFIQ) and 5-point Likert scale were used. Results: NRS and MSIS were significantly improved during each period. VAS, MMO, SIS, and SFS were significantly improved during each period, except the period from the $8^{th}$ to $10^{th}$ visit. MFIQ score was significantly improved during the period from the $1^{st}$ to $10^{th}$ visit. In the 5-point Likert scale, the results showed a high patient satisfaction with the treatment. Conclusion: These results showed that functional cerebrospinal therapy using an accurate balancing appliance, may be useful for reducing the symptoms of temporomandibular disorder.

  • Owing to the use of many cultural facilities, the elevation of life standards and the high level progress of industry, visual impairment was on increasing trends. Especially due to studying for many hours, the myopia of adolescents became a serious social issue. The purpose of this study was to understand adolescent's wearing glasses and eyesight condition, whether the primary myopia factor and the subjective symptoms were different between the myopia group and the normal group, between the wearing glasses group and the non-wearing glasses group, and the effect on physical, mental and study activity of myopia. The subject of investigation was 627 middle school students in Seoul and the investigation was accomplished from July 7th, 1993 to July 12th, 1993. The data were analyzed by the percentage, x²-test, t-test and ANOVA of SPSS. The results were as followed; 1. The rate of the right and left eyesights higher than 0.8 in the normal group was 47.0%, and those less than 0.7 in the myopia group was 53.0%. In the boy students, the normal group was 54.1%, the myopia group was 45.9%. In the girl students, the normal group was 39.2%, the myopia group was 60.8%. Therefore the girl students' myopia rates were higher than the boy students', and this result was significant(p<0.01). 2. The rate of wearing glasses of the middle school students was 44.6%. The rate of wearing glasses of the girl students was 56.8%. The rate of wearing glasses of the girl students was higher than that of the boy students 43.2%. The rate of necessary glasses of the middle school students was 6.1% and the rate of necessary glasses of the boy students was 7.9%, the rate of necessary glasses of the girl students was 4.1%. 3. In case of a family member of the student wear glasses, the rate of wearing glasses was higher. 4. In the myopia group, the main reason for not wearing glasses was "Uncomfortable"(63.3% in the boy students, 40% in the girl students). In case of the girl students, "Nonpermission of their parents" was 18.7% and remarkably higher than 5.1% in case of the boy students. 5. The factor of myopia was that "The bad attitude of watching TV closely" was 19.9%, that "The dimly-lit room" was 6.6%. 6. In order to protect eyesight, the rate of the students who practiced "Looking at something from afar 3∼4times a day" was 37.3%, the rate of the students who did "Eye exercise" was 17.5%, the rate of the students who took "A medicine for promoting nutrition" was 12.9%. The rate of taking the medicine was higher than 3.5% in the normal eyesight group. 7. After near working, the point of subjective symptoms was higher in the myopia group than in the normal group and in the wearing glasses group than in the unwearing group and in the girl students than in the boy students. 8. The longer time to watch TV, the higher point of subjective symptoms. The longer distance to watch TV, the lower point of subjective symptoms(p<0.05).

  • Background: In order to design effective educational intervention for cancer survivors, it is necessary to identify most-trusted sources for health-related information and the amount of attention paid to each source. Objective: The objective of our study was to explore the sources of health information used by cancer survivors according to their access to the internet and levels of trust in and attention to those information sources. Materials and Methods: We analyzed sources of health information among cancer survivors using selected questions adapted from the 2012 Health Information National Trends Survey (HINTS). Results: Of 357 participants, 239 (67%) had internet access (online survivors) while 118 (33%) did not (offline survivors). Online survivors were younger (p<0.001), more educated (p<0.001), more non-Hispanic whites (p<0.001), had higher income (p<0.001), had more populated households (p<0.001) and better quality of life (p<0.001) compared to offline survivors. Prevalence of some disabilities was higher among offline survivors including serious difficulties with walking or climbing stairs (p<0.001), being blind or having severe visual impairment (p=0.001), problems with making decisions (p<0.001), doing errands alone (p=0.001) and dressing or bathing (p=0.001). After adjusting for socio-demographic status, cancer survivors who were non-Hispanic whites (OR= 3.49, p<0.01), younger (OR=4.10, p<0.01), more educated (OR= 2.29, p=0.02), with greater income (OR=4.43, p<0.01), and with very good to excellent quality of life (OR=2.60, p=0.01) had higher probability of having access to the internet, while those living in Midwest were less likely to have access (OR= 0.177, p<0.01). Doctors (95.5%) were the most and radio (27.8%) was the least trusted health related information source among all cancer survivors. Online survivors trusted internet much more compared to those without access (p<0.001) while offline cancer survivors trusted health-related information from religious groups and radio more than those with internet access (p<0.001 and p=0.008). Cancer survivors paid the most attention to health information on newsletters (63.8%) and internet (60.2%) and the least to radio (19.6%). More online survivors paid attention to internet than those without access (68.5% vs 39.1%, p<0.001) while more offline survivors paid attention to radio compared to those with access (26.8% vs 16.5%, p=0.03). Conclusions: Our findings emphasize the importance of improving the access and empowering the different sources of information. Considering that the internet and web technologies are continuing to develop, more attention should be paid to improve access to the internet, provide guidance and maintain the quality of accredited health information websites. Those without internet access should continue to receive health-related information via their most trusted sources.

  • 본 논문은 피난조명 및 음성경보 기능을 내장한 화재경보시스템 개발에 관한 연구이다. 기존 화재감지기에 화재시 피난성능향상을 위해 가장 중요한 화재조기인지 및 피난시야확보가 가능하도록 피난조명 및 음성경보 기능을 자체적으로 내장한 화재감지기 및 시스템을 개발하여 성능을 확인하였다. 개발된 시스템의 경우 평균조도가 1.62 lx, 평균음향 89.7 dB, 평균음성 86.1 dB로 형식승인 및 제품검사 기술기준을 만족하는 것으로 나타났다. 추가적으로 개발된 시스템을 이용한 피난성능실험결과 본 실험조건에서 기존시스템보다 63.08%에서 67.82%까지 피난시간이 단축되는 것으로 나타났다. 개발된 시스템의 경우 자체 음성경보를 통해 화재인지 실패를 방지하고, 비상조명 점등을 통해 최소한의 피난을 위한 가시거리를 제공함으로써 화재피해를 최소화할 수 있고, 화재취약계층인 청각장애인 및 시각장애인까지 고려함으로써 당위성 및 효용성을 갖춘 화재경보시스템으로 활용될 것으로 생각된다.

  • Objective : Blepharoptosis is drooping of eyelid which causes impairment of visual field by covering partially or completely, and it is classified into congenital ptosis and acquired one. In western medicine, idiopathic blepharoptosis is usually treated by tarsectomy. Contrary to that concept, we consider eyelid is assigned to Yookryoon(肉輪) among Ohryoon(五輪) which matches to spleen. In oriental medicine, it can be treated by promoting spleen and kidney. Here I report two cases of idiopathic blepharoptosis improved by conservative acupuncture therapy and herb medicine. Methods : The changes in clinical symptoms of general body weakness, anorexia, dizziness, dry eye, etc, in degree of eyelid drooping and in individual expression were described as they were treated with acupuncture therapy, herb medicine, Bojoong-ikgi-tang(補中益氣湯) and some physical therapy including Negative, I.C.T, S.S.P and Carbon. Results : Symptoms(ex) general body weakness, anorexia, dizziness, dry eye, etc) at admission improved and disappeared gradually with acupuncture therapy and herb medicine. The patients could discharge with favorable recovery. Conclusions : In oriental medicine, blepharoptosis is mainly treated by promoting Qihyul(氣血) and enhancing flow of that. If the patient has deficiency of Suhnchun-poomboo(先天稟褓賦) and Mungmoon-hwa(命門火), he is treated by promoting Shin-yang(腎陽). If he is weak in Bee-qi(脾氣), he needs to be treated by strengthening Bee-yang(脾陽) where patient with lack of Ganhyul(肝血) is supposed to be treated by promoting Hyul(血). These following two cases were managed by acupuncture, herb medicine and physical therapy on idiopathic blepharoptosis.

  • 장애물 인식, 위치 확인, 색상 인식과 같은 스마트기기의 카메라를 활용한 시각 장애인을 위한 소프트웨어는 시각장애인의 삶의 질을 크게 향상시킬 수 있다. 그러나 기존의 카멜 기반 다양한 인식 소프트웨어들은 터치스크린에서의 시각장애인 접근성 요구사항을 제대로 반영하지 못하여 실제 시각 장애인이 사용에 있어 불편함이 있다. 본 연구에서는 최근 급속히 확산되고 있는 터치스크린 기반의 스마트 기기에서 카메라 기반 소프트웨어의 시각장애인 인터페이스의 접근성 요구사항을 도출하였다. 접근성 요구사항 도출을 위하여 상호작용 흐름이 서로 다른 3 가지 시험 인터페이스를 색상인식 응용으로 구현하여 시각 장애인을 대상으로 사용성 평가를 실시하였다. 평가 결과 크게 5 가지 접근성 요구사항을 도출하였다. (1)상호작용의 횟수가 적은 인터페이스를 선호한다. (2)사용자에게 각 화면 페이지마다 음성 도움말을 제공하기보다 초기의 음성 도움말을 제공하는 것이 더 중요하다. (3)사용자는 카메라를 수동으로 작동하는 것을 선호하며, 자동 모드를 선택할 수 있도록 지원하여야 한다. (4)운영체제 자체 접근성 기능은 카메라기반 애플리케이션이 실행 중인 동안 비활성화 해야 한다. (5)화면 경계에 대한 촉감 피드백이 필요하다. 도출한 요구사항을 반영한 시각장애인용 색상인식 소프트웨어의 인터페이스를 설계, 구현하고 이를 10명의 시각 장애인을 대상으로 도출한 접근성 요구사항이 유용함을 검증하였다.

  • Purpose: The aim of this study was to investigate correlations between the Functional Movement Screen (FMS), pain, and performance ability in professional fencing players. Methods: Fifty-six athletes participated in this study. The pain group included those who had a score on a pain-related Visual Analogue Scale (VAS) of ${\geq}$20 and an Oswestry Disability Index (ODI) score ${\geq}$10). In the non-pain group, these scores were: VAS(<20), ODI(<10). The VAS and ODI were used to measure pain throughout the study. Performance ability included motor function of the lower extremities (as assessed by a Modified Functional Index Questionnaire, MFIQ), dynamic balance (Balance system, BS and Posture med, PM), flexor and extensor muscle strength of the lumbar region was recorded as maximal isometric strength. Results: Among athletes who had pain, 5 of 15(33.33%) showed impaired functional movement. Conversely, only 2 of 41(4.88%) of those who had no pain showed such impairment (FMS ${\leq}$14score). The athletes who had pain and who had an FMS score above 14 (10/56; 17.86%) showed a significantly higher score for extensor muscle strength of the lumbar compared with those with pain and an FMS score below 14 (5/56; 8.93%) were significant correlations between the FMS and pain (r=-0.40 to -0.42, p<0.01), the MFIQ (r=-0.33, p<0.05), dynamic balance (r=-0.27 to -0.40, p<0.05-0.01), muscle strength of the lumbar (r=0.27 to 0.29, p<0.05). Stepwise multiple regression analysis showed that the dynamic balance score (${\beta}{\beta}$=-0.41) had slightly more power in predicting FMS score than pain, motor function of lower extremity, or muscle strength. Conclusion: The FMS was significantly associated with values of pain, motor function of the lower extremities, dynamic balance, and muscle strength of the lumbar. However the FMS appears to lack relevance and reasonable evidence to suggest that it is an acceptable measurement tool for functional movement analysis.
