The Change of Walking by Improvement of Ankle Joint Excursion

JooHyun Ham,Tamae Tanaka,Shigeki Yamabe 보완대체의학연구소 2014 Research Journal of Complementary and Alternative Vol.- No.5

A number of studies have been reported examining walking mechanisms, however the relationship between a walking mechanism (gait) and the presence of a deformed talus has not been fully elucidated. Therefore, we conducted this study focusing on understanding the causal relationship between talus deformity and gait with reference to the description on the decrease of the driving force component in ground reaction force in “Limited Range of Joint Motion: Mechanism and Treatment" by Minoru Okita et al. The result of our study demonstrated that a deformed talus caused the following changes: first, it led to turning of the knee/ankle joint which was caused by displacement of the ground reaction force movement locus from the ankle to the toe on the sole of the foot. Second, it reduced the step length by decreasing the ankle joint excursion in plantar flexion and dorsiflexion, by increasing ground reaction force when walking, and by the decrease of the driving force for toe off in the stance phase of walking. Moreover, it is possible to say that the study conducting with subjects including those who have pain in ankles and knees would clarify the relationship between the talus and walking mechanism in detail.

함주현 ( Joohyun Ham ) 사단법인 아시아문화학술원 2019 인문사회 21 Vol.10 No.4

영유아기는 생활습관의 기본이 형성되는 중요한 시기로 식습관의 경우 양육자의 태도가 큰 영향을 미치게 된다. 이에 본 연구에서는 영유아기를 보호하고 교육하는 학부모와 교사의 식습관의 관리 지도 필요성을 알아보고 교육 관리 방안의 자료 활용을 목적으로 수행하였다. 이를 위하여 영유아 교육기관 6곳의 학부모 266명과 교사 62명을 대상으로 설문 조사를 실시하였으며, SPSS 21.0 프로그램을 이용하여 빈도 분석, 교차분석, 요인분석, 독립표본 t-test를 실시하였다. 그 결과 식습관 교육의 필요성은 학부모와 교사 모두 높게 나타났고, 식습관 교육 필요의 목적은 ‘성장 후에도 좋은 식생활 유지’가 가장 높았다. 학부모와 교사의 식습관 지도의 인식은 학부모에 비하여 교사가 ‘식사행동 및 태도’, ‘식사예절’, ‘식사자립’, ‘청결’의 인식이 높게 나타나났으며, 식습관 관리 지도의 효과와 성인기의 영향에 대하여 학무모와 교사 모두 인식도가 높았다. 추후 영유아기 식습관 관리 지도의 인식과 실제 수행과의 차이에 대한 연구를 제언하며, 영유아기의 올바른 식습관 관리를 위한 양육자 및 교육자의 교육에 대한 주기적인 모니터링 관리 방안 마련이 요구된다. Early childhood is an important period in which basic lifestyles are formed, in which the fosterer’s attitude has a great impact on the child’s eating habits. Thus, this study was conducted to examine the necessity of management and guidance of eating habits by parents and teachers who protect and educate children in early childhood and to utilize the result as a material for preparing a plan for education and management. For this purpose, a survey was conducted with 266 parents and 62 teachers in six educational institutions for young children, and frequency analysis, Chi-Square Test, factor analysis, and independent-sample t-test were conducted, using SPSS 21.0 Software. As a result, the necessity of education of eating habits was high in both the parents and the teachers, and “to maintain good eating habits after grown-up” was the highest purpose when the education of eating habits was necessary. As for the awareness about the guidance of eating habits by parents and teachers, there was a difference, as the teachers had higher awareness about “eating behavior and attitude”, “eating etiquette”, “self-feeding”, and “cleanliness,” as compared to the parents, and both the parents and the teachers had high awareness about the effect of the management and guidance of eating habits and its impact on adulthood. This study proposes a study of the difference between awareness about the management and guidance of eating habits during early childhood and actual performance, and it is necessary to prepare a plan for education for fosterers and educators and periodic monitoring and management for the right management of eating habits during early childhood.

본 연구는 이륜자동차를 이용한 음식업 배달 종사자의 사고 경험과 산재보험 및 상해보험의 가입 실태를 파악하여 안전 관리 방안 마련의 기초 자료로 활용하기 위하여 수행되었다. 이를 위하여 음식업 배달 종사자 635명을 대상으로 설문 조사 후 통계 분석을 실시하였다. 그 결과 음식 배달 중 사고 경험은 배달전문업체, 중국음식, 치킨 순으로 높게 나타났으며, 주요 사고 내용과 원인은 넘어짐, 미끄러짐으로 나타났다. 교통 사고 경험은 배달전문업체, 중국음식, 패스트푸드가 높게 나타났으며, 차량과의(자동차, 트럭 등) 사고가 많은 것으로 나타났다. 세부 음식업종은 배달대행 또는 사업장의 이륜자동차 이용이 많았으나 배달전문업체는 개인 소유가 많았으며, 이륜자동차의 등록과 보험 가입은 패스트푸드가 가장 높게 나타났다. 음식업 배달 종사자는 사회 및 상해 보험에 대하여 73.9%가 인식하였고, 보험료에 대한 사업주의 부담이 큰 경우 가입 의사가 높은 것으로 나타났으며, 상해보험은 개인 가입이 많은 것으로 나타났다. This study was carried out to grasp the experiences of accidental delivery of food service delivery workers using motorcycles and the status of participation in industrial accidents insurance and accident insurance, and to utilize them as basic data of safety management plan. For this, statistical analysis was carried out after questionnaire survey of 635 delivery workers. As a result, the experience of the accident during the food delivery was high in the order of the delivery specialist, the Chinese food, and the chicken, and the main accident contents and causes were found to fall and slip. Traffic accident experience was high in delivery specialists, Chinese food, fast food, and many accidents with cars (cars, trucks, etc.). As for the subcategories of food industry, there were a lot of use of delivery cars or bicycles in the workplace, but many of the delivery specialists were privately owned. Fast food had the highest rate of registration and insurance of motorcycles. 73.9% of the workers in the catering industry were aware of social and accidental insurance, and when the burden of the employer on the insurance premium was large, the intention to join was high.

Ham, Giyul,Shin, Seokyoon,Park, Joohyun,Choi, Hagyoung,Kim, Jinseo,Lee, Young-Ahn,Seo, Hyungtak,Jeon, Hyeongtag American Chemical Society 2013 ACS APPLIED MATERIALS & INTERFACES Vol.5 No.18

<P>In this study, tin sulfide thin films were obtained by atomic layer deposition (ALD) using Tetrakis(dimethylamino)tin (TDMASn, [(CH<SUB>3</SUB>)<SUB>2</SUB>N]<SUB>4</SUB>Sn) and hydrogen sulfide (H<SUB>2</SUB>S). The growth rate of the tin sulfides (SnS<SUB><I>x</I></SUB>) was shown to be highly dependent on the deposition temperature, and reaction times of 1 second for the TDMASn and H<SUB>2</SUB>S were required to reach the saturation regime. Surface morphologies were smooth or rectangular with rounded corners as observed by a field emission scanning electron microscope (FE-SEM) and were dependent on temperature. X-ray diffraction results confirmed that the crystal structure of SnS<SUB><I>x</I></SUB> can be tuned by changing the ALD temperature. Below 120 °C, SnS<SUB><I>x</I></SUB> films appeared to be amorphous. In addition, SnS<SUB><I>x</I></SUB> films were SnS<SUB>2</SUB> hexagonal at 140 and 150 °C and SnS orthorhombic above 160 °C. Similarly, the values of the optical band gap and binding energy showed significant differences between 150 and 160 °C. The electronic structures of SnS<SUB><I>x</I></SUB> were extracted by UPS and absorption spectroscopy, and the unsaturated Sn 3d molecular orbital (MO) states in the band edge were found to be responsible for the great improvement in electrical conductivity. This study shows that TDMASn-H<SUB>2</SUB>S ALD is an effective deposition method for SnS<SUB><I>x</I></SUB> films, offering a simple approach to tune the physical properties.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/aamick/2013/aamick.2013.5.issue-18/am401127s/production/images/medium/am-2013-01127s_0009.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/am401127s'>ACS Electronic Supporting Info</A></P>
