영상처리 기술은 현대 사회에서 다양한 분야에 응용될 수 있다. 현대인들이 관심을 가지고 있는 헬스케어도 그 분야 중 하나이다. 운동기구등을 가지고 하는 헬스케어는 정확한 동작이 우선시 되어야 하는데, 일반인들은 비용의 문제 등으로 혼자서 운동을 하고 있는 실정이다. 이러한 경우에는 운동의 효율성을 보장할 수 없고, 때에 다라서는 운동자에게 역효과가 나기도 한다. 본 논문에서는 영상처리 기술을 이용하여 일반인이 혼자서 운동을 할 때 자세를 잡아 주고 교정해 주는 프로그램을 개발하였다. 사용자들은 운동 시 본 프로그램을 통하여 정확한 자세를 가르치는 개인트레이너를 고용하는 효과를 얻을 것으로 기대한다.

In this study, we present a method for correcting unbalanced sitting posture alignment to its optimal position, by designing a chair equipped with pressure sensor. With increasement in sedentary work, such as office work or study, people are now spending more time in chair. To accommodate sedentary life styles, many chairs are being designed for a comfortable sitting condition. However, without awareness and efforts for correct sitting posture, it may not be possible to achieve such condition. When the weight is not distributed evenly while sitting, it may cause various diseases such as scoliosis and a herniated disc. Being inspired by such facts, we have progressed basic researches to maintain the correct sitting posture. To demonstrate the proof-of-concept validation, we installed a series of sensors to a chair and then measured the changes in pressure distribution in various postures. The results show that this approach can be potentially helpful for understanding how fundamental problems due to unbalanced sitting posture can be corrected and maintained properly.

최근 올바르지 못한 자세로 인하여 척추 측만증 등의 질환을 가지고 생활하는 사람의 수가 늘고 있다. 이러한 다양한 질환의 치료를 위한 자세 교정은 시간과 비용이 소요되며 지속적인 관찰이 필요하다. 본 논문에서는 소형 기울기 센서를 목과 허리에 장착하여 신체의 기울기를 실시간으로 관찰함으로써 자세 이상을 기록하고 경고하여 불완전한 자세를 교정하는 보조 시스템을 제안하였다. 가속도와 자이로 센서를 이용하여 신체의 올바르지 못한 자세의 기울임을 감지하여 경고 신호를 내 보내고 시간에 따른 자세의 변화를 외장 메모리에 기록하여 분석할 수 있도록 하였다.

For design research of teenagers' posture correcting shirt, postures of teenagers were analyzed and became the base of inventing suitable patterns. The subjects of this study were 198 of both female and male middle school students from the city of Seoul. Students' postures in classroom and length change of body surface were observed and analyzed; based on this, total of 5 postures was selected, and length changes of body surface were applied. The patterns in this study were designed with stretch material to help antagonism by muscle movements. Each fabric that was used in this study had 110% of stretch, 120~140% of stretch, and 150~170% of stretch. Both of one-way-fabric and duplex-fabric were used in this study, depending on application site.

As smart phone became popular, its excessive uses cause adverse effects called smart-phone syndrome such as Turtle-neck syndrome in physical side and smart-phone addiction in mental aspects. Turtle-neck syndrome incurred by incorrect posture when you watch smart-phone, which causes a serious health problems. However, these syndromes can be detected by gyro-sensor and timer, and prevented by correcting the posture and halting the function with smart-phone application (App). Thus, this paper proposes App that helps user to realize bad posture and addiction to smart-phone, and to acquire the correct habit by inducing user to stretch neck or to stop operation with warning message. If we tried to adjust bad posture and addiction in using smart-phone through this application, the social losses from smart-phone syndrome would be minimized as a result.

This study was designed to provide basic data for developing exercise program that helps correcting posture by knowing the effect of strengthening and elongation exercises of upper extremity muscle to forward head posture correction. In this study determined subjects whether they had forward head posture or not. On the basis of the New York state posture rating, if a subject's posture is match up with the normal standard posture, gives 5 points and if the posture is slightly get out of the normal standard posture, gives 3 points and if the posture is apparently get out of the standard, gives 1 points. When determining the forward head posture, if talus, humerus and outer ear center are on the same line, it is determined as normal and if outer ear center is off the line less than 1.0cm, it is a slight deformation and if outer ear center is off the line more than 1.0cm, it is a high deformation. In the study selected people who have more than 1 cm gap between two vertical lines start from outer ear center and acromion separately as subjects. Length between the ideal alignment line measured by using goniometer and temporal region showed statistically significant decrease as $2.36{\pm}1.07cm$ before the intervention and $1.06{\pm}0.88cm$ after the intervention. After 4 weeks of neck and chest extensor muscle exercise, the group who exercised both showed increase in range of neck joint motion and neck flexion of the forward head posture. Meanwhile the group who only exercised neck extensor muscle only and the group who only exercised chest extensor muscle didn't showed statistically significant result. That only the group who exercised both muscles showed significant result is the different with studies before. Because this study didn't target patient who had a lesion, couldn't compare effect of the conservative manner and exercise. However, this study provides the fact that the group who exercised both neck and chest muscle had more effect than the control group.

ICT 산업 종사자 수의 증가에 따라 VDT 증후군 예방을 위한 연구가 요구되고 있다. 기존의 자세 교정 제품들은 대부분 카메라 의존도가 높거나 웨어러블 기기의 센서에만 의존하고 있다. 본 논문에서는 내장 카메라와 원형 압력 센서를 활용하여 자세 정보를 수집하는 자세 교정 시스템을 개발하였다. 또한 초기 사용자의 '바른 자세'를 입력받고 이를 기반으로 사용자의 자세를 모니터링하는 맞춤형 서비스를 제공한다. 본 시스템은 사용자의 일상 업무 중 자세를 정밀하게 교정함으로써 VDT 증후군을 예방 및 개선하며 최종적으로 ICT 산업 종사자의 업무 효율 향상을 기대할 수 있다.

In this paper, we present a wearable measurement system for monitoring rounded shoulders. The system contains a shoulder correction band and a stretch sensor that can correct and measure shoulder posture, respectively. The capacitance of the stretch sensor changes linearly according to changes in the shoulders. To verify measurement, a motion analysis system was used as the reference to compare the change in the rounded angles of the shoulders and the change in the stretch sensor's capacitance. The results indicated that there is a high correlation between the two changes and the system can be used as a monitoring device for rounded shoulders.

Purpose: This study examined the correlations between a forward head posture and the endurance and maximal voluntary contraction of the deep neck flexor, neck pain, and the changed position of the mandible. Methods: The subjects of this study were 50 male and female adults who work at a desk for at least four hours a day. The head-spine angle was photographed with a camera, and the endurance and maximal voluntary contraction of the deep neck flexor and the changed position of the mandible were measured using pressure biofeedback. The Neck Disability Index was used to measure neck pain. To examine the correlations between a forward head posture and the endurance and maximal voluntary contraction of the deep neck flexor as well as the changed position of the mandible, a Spearman's correlation analysis was conducted. The statistical significance was set at 0.05. Results: A forward head posture and the endurance of the deep neck flexor showed a statistically significant positive correlation, and a forward head posture and neck pain showed a statistically significant negative correlation. In addition, the endurance of the deep neck flexor and neck pain showed a statistically significant negative correlation. Conclusion: The results of this study show that a forward head posture and the endurance of the deep neck flexor were correlated; in addition, a forward head posture and neck pain were correlated. Therefore, enhancing the endurance of the deep neck flexor can assist in correcting an imbalanced forward head posture, which can reduce neck pain.
