126 male and 95 female Korean college students were examined for Scoliosis by using Moire type body observation apparatus. Scoliotic hump measuring instrument, and spinal cord side curvature condition measuring instrument. The prevalence rate of Scoliosis along with identifying its possible causal factors and characteristics were investigated. The results revealed that 5.56% of male and 8.42% of female students(male to female ratio 1:1.47) were suspected as having Scoliosis. There was a significant correlation between the students who have symptoms of Scoliosis and their physiological measurements(e.g., lower breathing capacity of the lungs). There were also close relationships between the suspected cases and their habits(e.g., poor sitting and sleeping posture). It is concluded that the Scoliosis in Korean college students should not be ignored.

This study was designed to investigate the relationships between children's physical growth and health and their raising conditions and to find out the important conditions to improve their physical growth and health. The rasing conditions were classified into three major parts; i. e., family conditions, conditions of nutrition up-taking, and conditions of rest or sleep and exercise or play. Then, the questionnaire including the items to survey these three areas of raising condition and the items to evaluate the health status were given to children' mothers or fathers and filled up by them. The data of their 4 anthropometric measures; body weight, stature, sitting height and chest girth, were also collected from their latest records of health examination. The data of health status were converted to health scores representing 6 domains of health; digestive organs, respiratory organs, auto-nerve systems, fatigue, others and health as a whole. Then, correlations of raising conditions were determined with four antropometric measures and 6 health scores as criterion variables. Then, number of families to live together, and child's birth order in the domain of family conditions, habits of unbalanced diet, eating frequency of eggs, fruits, green and yellow vegetables, light colored vegetables, milk products in the domain of nutrition up-take, and the time for study at home, the place for play, the number of friends to play with together, the hours for playing out of door, the hours for playing sports, and the hours to move their body for assisting house keeping were picked out to investigate their relationships with physical growth and health status. Then, their habits of unbalanced diet and eating frequency of eggs, green or yellow colored vegetables, and milk products were found more influential conditions and more over, birth order, the time for study at home, the time to play out of door showed moderate degree of connection with physical growth and health status in early childhood.

The otitis media has the highest rate of occurrence in 6-36 month after birth, and relatively high rate of occurrence to six years old. It is one of major cause for hearing loss problem because of its high rate of recurrence. The researcher observed at bed that feeding posture and feeding habit at night have some relationship with occurrence of otitis media. I found that medical research in this area was very weak, and it caused her to concentrate her research on the topic. This paper was undertook a retrospective case-control study to find out the relationship between the mode of feeding and the occurrence of otitis media among the otitis media patients and the healthy persons. As the controling groups, the researcher chose fifty eight mothers whose children received the treatment of otitis media(6-36 months after birth) from the pediatrics clinic of two general hospitals in Seoul, as the patient group, and forty five mothers who consulted with their child to well baby clinic at the general hospital and kindergarten in Seoul as the control group. The results of the survey can be summarized as followed : 1. "Otitis media patient group may have more lying posture mothers while feeding than the healthy control group". The first hypothesis is supported by the fact that the children who have lying posture feeding habit mothers are more easily exposed to otitis media than those who have sitting posture feeding habit mothers as the analysis show : $X^2=8.142$, p = .017 2. "Otitis media patient group may have higher rate of sleeping habit with milk bottle on the month at night than the healthy control group does". The second hypothesis was supported by the fact that the patients group has higher rate of expected sleeping habit than the healthy group dose as the analysis show : $X^2=4.35$, p = .037 3. "Otitis media can be found more in the artificial feeding group than in the healthy children group". The hypothesis is rejected by the analysis, $X^2=1.550$, p = .416. Though the hypothesis is not supported by this research, we need to encourage mothers to feed mother's breast milk on the ground that healthy group has mother's milk feeding tendency, and the best food for infants is their mother's milk, and psychological-sociological effects of breast feeding os quite good for children. It will improve the health of infants. It can be summarized as follows : Otitis media is more concerned with posture of feeding and night feeding habits than feeding modes. On the basis of this survey, feeding education problem for mothers of infants need to be developed. In the education, sitting-embracing posture of feeding, mother's breast feeding, and prohibition of children's lying posture feeding at night need to be emphasized.

Objectives : This research was conducted to find the subjective symptoms of musculoskeletal system for main jobs and job posture. Methods : A survey was conducted from September 15, 2011 to October 7, 2011 and 357 dental hygienists were responded. The survey was consisted of the working environment and medical equipments, psycho-social characteristics, health habits and education, job posture, subjective symptoms of musculoskeletal system pain, and so on. Results : In the survey on the frequency of job posture of dental hygienists by jobs, said they cast down or tilt their head by 15 degrees or more or twist or bend their back. The result of the analysis on the subjective symptoms of musculoskeletal system by main job showed that they experienced a pain in neck, shoulder, and back, although the order differed. The order of subjective symptoms of musculoskeletal system for casting down or turning head by 15 degrees or more, twisting or bending back, having shoulders not parallel to the ground, sitting at the end of a chair, and supporting the whole body with one leg or pressing on a pedal for treatment was from the shoulders to the neck to the back. The order of subjective symptoms of musculoskeletal system for having arms too far from the body or hunching for treatment and bending wrists inward or outward for treatment was from the shoulders to the back to the neck. Conclusions : Due to the characteristics of the job which requires one to have a proper view of a patient's oral cavity, most of the postures included casting down of head or bending of back. Therefore a development of new postures is needed to replace the existing job postures which pressure the musculoskeletal system. And shift rotation can be used as a preventive measure.

As a kind of personal lifelog data, activity data have been considered as one of the most compelling information to understand the user's habits and to calibrate diagnoses. In this paper, we proposed a robust algorithm to sampling rates for human activity recognition, which identifies a user's activity using accelerations from a triaxial accelerometer in a smartphone. Although a high sampling rate is required for high accuracy, it is not desirable for actual smartphone usage, battery consumption, or storage occupancy. Activity recognitions with well-known algorithms, including MLP, C4.5, or SVM, suffer from a loss of accuracy when a sampling rate of accelerometers decreases. Thus, we start from particle swarm optimization (PSO), which has relatively better tolerance to declines in sampling rates, and we propose PSO with an adaptive boundary correction (ABC) approach. PSO with ABC is tolerant of various sampling rate in that it identifies all data by adjusting the classification boundaries of each activity. The experimental results show that PSO with ABC has better tolerance to changes of sampling rates of an accelerometer than PSO without ABC and other methods. In particular, PSO with ABC is 6%, 25%, and 35% better than PSO without ABC for sitting, standing, and walking, respectively, at a sampling period of 32 seconds. PSO with ABC is the only algorithm that guarantees at least 80% accuracy for every activity at a sampling period of smaller than or equal to 8 seconds.

Objectives The main aim was to quantify forward head posture using POM Checker®, a postural balance analyzer, among elementary school students. Additionally, the study aimed to investigate whether postural imbalance improved following three sessions of the school doctor program focused on body posture correction. Methods The program was conducted as part of the school doctor program in Korean Medicine, featuring lectures by a designated Korean Medicine doctor at an elementary school. The curriculum covered the importance of maintaining correct posture and included posture correction exercises. Pre- and post-program self-reported surveys were administered, alongside postural measurements taken over three months at one-month intervals. The survey included data on gender, grade, lifestyle habits, and awareness of correct posture. Result Out of 73 participating students, 63 underwent body balance measurements from the upper grades of one elementary school. Survey results revealed significant variations in daily sitting hours and weekly exercise levels. Attendance at lectures increased knowledge about correct posture. Initial measurements of forward head posture categorized 41.0% and 1.6% of participants into caution and risk groups, respectively. After the second measurement, the caution group representation decreased to 3.2%, and by the third measurement, only 1.6% of participants remained in the caution group. Conclusions Improvements in the angle and understanding of forward head posture among elementary school students were observed before and after the Korean Medicine school doctor program. However, posture improvement may be temporary, necessitating consistent follow-up management and monitoring.

본 연구에서는 보육교사의 배식관리 및 식사지도에 대한 중요도와 수행도를 파악하기 위하여 서울시 금천구의 어린이집에 근무하고 있는 보육교사 179명을 대상으로 2013년 12월에 설문조사를 실시하였다. 응답한 어린이집의 유형은 가정 어린이집 (39.7%), 민간 어린이집 (31.8%), 국공립 어린이집 (28.5%) 순으로 많았다. 요인분석 결과, 보육교사가 수행하는 배식관리 및 식사지도는 '개인 위생관리 (요인 1)', '식사지도 (요인 2)', '식재료 위생관리 (요인 3)', '맞춤형 배식 서비스 (요인 4)'의 총 4개의 요인, 11개의 항목으로 추출되었다. 보육교사는 '배식 시 위생모를 착용한다', '배식 시 일회용 장갑을 착용한다' 등의 요인 1 (개인위생관리)과 관련한 항목에 대한 중요도를 가장 낮게 인지하고 있었으며 수행도도 가장 낮았다, 반면 '영유아의 연령을 고려하여 음식을 잘라서 배식한다', '영유아의 연령별로 1인 분량을 달리하여 배식한다'의 요인 4 (맞춤형 배식서비스)와 관련된 항목에 대한 중요도를 가장 높게 인지하고 있었고 수행도도 가장 높았다. 중요도-수행도 분석 결과, 중요도와 수행도가 모두 높은 1사분면에는 '영유아의 식습관을 격려하고 칭찬한다', '식사 전 후 감사인사를 한다', '영유아와 함께 앉아 식사한다' 및 '영유아의 연령을 고려하여 음식을 잘라서 배식한다'의 4개 항목이 포함되어 있었다. 이에 비해 중요도와 수행도가 모두 낮은 3사분면에는 '배식 시 위생모를 착용한다', '배식 시 일회용 장갑을 사용한다', '배식 시 배식용 앞치마를 착용한다', '영유아의 연령별로 1인 분량을 달리하여 배식한다'의 4개 항목이 포함되어 있었다. 중요도는 낮다고 인지하고 있으나 수행도는 높은 4사분면에는 '조리 완료 후 2시간 이내에 배식한다', '먹다 남은 우유 (분유)를 바로 버린다', '식사 중 영유아의 이름을 부르며 대화한다'가 포함되어 있었다. 본 연구결과, 전반적으로 보육교사는 배식과 관련한 정부 지침에 대해 중요하다고 인식하고 있었으며 현장에서 이를 수행하고 있는 것으로 파악되었다. 그러나 보육교사는 배식 시의 개인 위생관리 및 식재료 위생관리에 대해서는 중요하다고 인지하는 정도가 맞춤형 배식 서비스에 비해 낮은 것으로 나타났다. 특히 개인 위생관리는 중요도뿐만 아니라 수행도도 낮은 것으로 나타났다. 이에 보육교사를 대상으로 개인 위생관리의 중요성에 대한 교육이 실시 되어야 하며, 특히 배식 시의 위생적인 복장 착용에 대한 주제로 한 교육이 필요할 것으로 생각된다. 또한 보육교사가 이를 실천할 수 있는 어린이집의 급식 환경 마련이 필요할 것으로 생각된다. 이를 위해 정부 및 관련 기관에서는 보육교사를 대상으로 한 위생교육을 지속적으로 제공하고 교육 이론을 현장에 적용할 수 있도록 환경을 조성해야 한다.
