In this study, the properties of various material combinations were evaluated and an ideal material for fabricating protection pads for women's army combat uniforms was determined. Eight specimens were used for the evaluation: two types of materials, namely thermoplastic polyurethane for 3D printing, T and ethylene-vinyl acetate, E; two infill densities, namely 10%, 10 and 30%, 30; two types of pad designs, i.e., without holes, A and with holes, B; 2×2×2=8 and control E. The tensile strength, flexural strength, impact absorption, and weight of these specimens were evaluated. Results revealed that E was the most flexible material; however, its tensile strength and impact absorption were very low. Protection pads made from T (T-10A, T-10B, T-30A, and T-30B) had excellent tensile strength and impact absorption; however, they had low performance in ease of movement. Alternatively, protection pad with holes and an infill density of 30% produced using a combination of T and E had a high initial tensile modulus and exhibited excellent impact absorption. Moreover, it was flexible and light, which satisfies the standards and conditions required by protection pads. However, if T-E-10A and T-E-30B exhibited low impact absorption, as required, they can be regarded as appropriate materials for protection pads.

Purpose: This study investigated the effects of motion taping on muscle stiffness, muscle tone, and pain in middle-aged women with shoulder impingement syndrome. Methods: The participants comprised 30 middle-aged women with shoulder impingement syndrome. This study measured muscle stiffness, muscle tone, and pain. In the experimental group, the tape was attached after physical therapy; the control group only received physical therapy. In the intervention period, the treatment program was conducted three times a week for a total of four weeks, and the values before and after the intervention were compared and analyzed. For statistical processing, a correspondence test was performed before and after the intervention at a significance level of 0.05, and the comparison between the groups, before and after the intervention, was made using an independent test. Results: In the experimental group, there was a difference in muscle stiffness, muscle tone, and intensity of pain. In addition, there was a significant difference between the control group's emotional domain regarding muscular stiffness and pain and the experimental group. However, there was no significant difference in muscle tone and grade of pain, and intensity of pain for the control group. Conclusion: This study showed that, when physical therapy and motion taping were administered to middle-aged women with shoulder impingement syndrome, it had a more positive affect on the sensory and emotional parts of the muscle tone and pain compared to physical therapy alone.

Background: Falls are a common and serious problem in the elderly population. Muscle strength and balance are important factors in the prevention of falls. The Y-balance test (YBT) is used to assess dynamic postural control and shows excellent test-retest reliability. However, no studies have examined the relationship between lower-limb strength and YBT scores in elderly women. Objects: This study aimed to examine the relationship between lower-limb strength and YBT scores in elderly women. Methods: Thirty community-dwelling elderly women participated in the study. Lower-limb strength including hip flexor, hip extensor, hip abductor (HAB), hip adductor (HAD), knee flexor, knee extensor, ankle dorsiflexor, and ankle plantar flexor (PF) muscles was examined using a smart KEMA strength sensor (KOREATECH Inc.), and the YBT was used to assess dynamic balance. Relationship between lower-limb strength and YBT was demonstrated using a Pearson's correlation coefficient. Results: HAB strength (r = 0.388, p < 0.05), HAD strength (r = 0.362, p < 0.05), and ankle PF strength (r = 0.391, p < 0.05) positively correlated with the YBT-anterior direction distance. Ankle PF strength was positively correlated with the YBT-posteromedial direction distance (r = 0.396, p < 0.05) and composite score (r = 0.376, p < 0.05). Conclusion: The results of this study suggest that HAB, HAD, and ankle PF strengths should be considered for dynamic postural control in elderly women.

Japanese welfare legislation for the disabled was enacted via Law 283 on December 26. 1956. The push for such legislation at the national level had gown concurrent with development of Japan's post-war economy Korean welfare law for disabled was made 22 years later and was again amended in 1989. The current legislation promotes and supports the legal welfare of the Koran disabled. The following are the results of a comparison between Korean and Japanese accessibility facilities and welfare law; 1) Japan's developement of disabled people's welfare law is inextricably linked to the development of disabled people's advocacy and the human rights movement. In addition, welfare policy has shifts its mandate from rehabilitation to independent living. It follows that local altitudes will play a pivotal role in further policy initiatives. Korean disabled people's welfare policy emerged hand in hand with economic recovery and development following the Korean War. By 1977 a special education law was enacted which-like it Japanese counterpart-promoted the education of disabled children. 2) Accessibility facilities were developed privately movement. The disabled faced constant and systematic disadvantages in public/private buildings and transportation systems. A general lack of cultural awareness and information relating ti these problems prevailed. These included-hut were by no means limited to sign language (for hearing the impaired) and braille(the language of blind). However, new attitudes and improvements have since emerged and new laws have resulted in the publication of Korean 'White Book' outlining the everyday problems faced by the disabled. In addition, mort convenient access facilities have been constructed in public and private buildings. In closing, legal support for the disabled, senior citizens and pregnant women continues to be improved by newer legislation enacted tin April 6, 1977.

가상의 캐릭터가 이동하기 위해 경로를 계획하는 일은 컴퓨터 게임을 포함한 여러 응용 분야에서 필수적인 문제이다. 기존의 로봇 경로 계획과는 달리 하나 이상의 캐릭터가 그룹 이동을 하는 경우가 많으며 이 경우에는 이동 경로의 최단 여부보다는 자연스러운 그룹 이동 등의 질적인 면이 강조된다. 본 논문에서는 리더로 정해진 단일 캐릭터에 대해 정적인 환경에서의 전역 경로를 계획하고 이 경로를 따라 그룹이 이동하며 동적 장애물을 피하도록 지역 경로를 계획하는 2단계 경로 계획 방법을 제안한다. 그룹이 이동할 수 있는 공간은 리더를 중심으로한 정방형 격자 배열을 이용하여 확보하고 이를 격자창이라고 부른다. 멤버 캐릭터들은 격자창 공간 안에서 리더에 대한 상대적인 위치를 잡아 이동하며 격자창이 이동할 수 있는 경로를 계획하기 위해 정적 환경을 격자창에 대한 형태 공간으로 치환하여 로드맵을 구한다. 지역 경로 계획 단계에서는 리더에 대해 인공 포텐셜 필드를 이용하여 동적 장애물을 회피하도록 하고 나머지 멤버들에 대해서는 격자창 내에서 리더에 대한 상대적인 위치를 확보하는 방법으로 연산량을 줄인다. 제안하는 경로 계획 방법을 구현하기 위한 효율적인 알고리즘을 소개하며 정적 환경에서 계획된 경로를 따라 그룹이 이동하면서 동적 장애물에 대해 효과적으로 대처하는 것을 시뮬레이션을 통해 보여 준다.

The purpose of this investigation was to know correlation of mean values between centric occlusion and centric relation by the cephalogram in Angle's Class Ⅰ and Ⅲ malocclusion subjects. 22 adults with Angle's Class Ⅰ malocclusion (17 men and 5 women, 21 to 27 years of age) and 14 adults with Angle's Class Ⅲ malocclusion (10 men and 4 women, 21 to 27 years of age) were selected from the dental students in Yonsei University. Each subject was given two lateral cephalometric radiographies and cephalometric analysis was performed. All data from these analyses was recorded and statistically processed with CYBER computer system. 1. The results were obtained as follows: There was a strong positive correlation between centric occlusion and centric relation in all subjects with Angle's Class Ⅰ and Ⅲ malocclusion. 2. In Angle's Class Ⅰ malocclusion, measurements in lower facial height revealed significant difference between centric occlusion and centric relation (P<0.05). In Angle's Class Ⅲmalocclusion, measurements in facial axis angle, mandibular plane angle, convexity of A point, lower incisor protrusion, lower facial height revealed significant difference between centric occlusion and centric relation (P<0.05). 3. When the mandible was moved from centric occlusion to centric relation, the mean distance of mandibular movement was 1.27㎜ (0.2-2.8㎜) in Angle's Class Ⅰ malocclusion, 1.70㎜ (0.55-4.15㎜) in Angle's Class Ⅲ malocclusion, and 1.44㎜ (0.2-4.15㎜) in all subjects.

The purpose of this study is proposing a knitting method that is suitable for the bodies of women in their 20's and can enhance aesthetic aspect and wearing satisfaction. For this study, four kinds of seamless knit one-pieces were implemented by different knitting method of waist dart each other. The inspection of the exterior and the sensory test of movement adaptability were included in this study. The results of this study were listed below. Exterior evaluation of the four samples results that the sample with outside narrowing and widening get low grade. Thus, we can see that the method having only outside narrowing and widening for waist shaping can cause problems. In addition to that, the sample with inside narrowing and widening get highest grade for almost all test items. The dressing evaluation results that the knitting method of waist dart affect only on the exterior but not on the movement adaptability of the seamless knit one-piece.

This study evaluated designs via the consumers' function and design preferences survey for using product design images, virtual avatar wearing images and product explanations that identified consumers' function and design preferences for knee protection pads as well as to develop movement assistive knee pad designs. We developed Design A for men and Design B for women. For Design A, the front of the knee supports muscles and alleviates pain with a hole. Mesh material with good ventilation was applied to enhance wearing comfort. The color was achromatic for a modern style, and the hook fastener and loops enabled easy wear and removal of the pad while controlling size and pressure strength. For Design B, taping details seamlessly support muscles in the knee area with fabrics less than 0.1 cm thick and with long sleeves in the diverse sizes. The design's satisfaction assessment showed that potential consumers were satisfied with Design A and Design B for overall design and functional features. Over 77% wanted to use/wear and purchase designs; in addition, over 78% expected it would help with walking and relieve knee pain. The results can be helpful for designers when deciding designs for manufacturing and commercializing kneepad products.

This study is based on anthropometric data from the 7th Size Korea, we selected five subjects with measurements similar to average women in their twenties. The subjects participated in adaptability assessments and appearance assessments of skinny jeans produced by 8 selected brands, to identify the pattern and measurements characteristics of jeans assessed to be superior in appearance and movement adaptability. The results of this study were as follows. First, according to the results of appearance assessment made by the specialist group, B brand earned the highest assessment in response to questions regarding if 'there is an appropriate amount of ease in the crotch area' on the front side and 'an appropriate amount of ease in the hip circumference area' on the back side. Based on the above results, Synthesizing the survey results and the appearance assessment and movement adaptability assessment results, we suggest that when drafting the pattern for the standard size of waist measurement 27 inches (67cm), the hip circumference should be given an appropriate amount of ease, of around -6.6cm (-7.2%). The thigh circumference should be set with an appropriate amount of ease, which is -5.3cm (-9.4%).
