Background Chronic wounds occur due to failure of the normal healing process, associated with a lack of deposition of cellular components and a suitable microenvironment such as the extracellular matrix (ECM). Acellular dermal matrix (ADM) is viewed as an ECM substitute, and a paste-type ADM has recently been introduced. We hypothesized that CGPaste, an injectable paste-type ADM, could serve as a scaffold and promote wound healing. Methods We retrospectively studied seven patients in whom CGPaste was applied between 2017 and 2018, who had pressure ulcers, necrotizing fasciitis, diabetic foot ulcers, traumatic defects, and osteomyelitis. The goal of applying CGPaste was to achieve complete wound healing with re-epithelialization or growth of granulation tissue, depending upon the wound bed status. CGPaste was injected based on the wound size along with the application of a dressing. Results Four of the seven patients showed granulation tissue on their wound bed, while the other three patients had a bony wound bed. The mean wound area was $453.57mm^2$ and the depth was 10.71 mm. Wound healing occurred in five of the seven patients (71.43%). The mean duration of complete healing was 2.4 weeks. Two patients showed failure due to paste absorption (29.57%); these patients had wound beds comprising bone with relatively large and deep wounds ($40{\times}30$ and $30{\times}20mm^2$ in area and 15 and 10 mm in depth). Conclusions CGPaste is an effective option for coverage of small and deep chronic wounds for which a flap operation or skin grafting is unfeasible.

We studied the effect of vibratory stimulations of different leg muscles, tibialis anterior(TA) and triceps surae(TS), and plantar zones in ten healthy subjects during 1) quiet standing, 2) forward lean of body, 3) backward lean of body, 4) right lean of body, and 5) left lean of body. The experiments were performed on the force platform. The effect of vibration were measured by monitoring the area of COP(Center of pressure) sway. The subjects wore a vibratory stimulation system on foot and ankles and were given the instruction not to resist against the applied perturbations. The results show that all vibratory stimulations to lower limb muscles and plantar zones reduced the COP sway area. This reduction of the COP sway area occurred also in partial vibratory stimulations during quiet standing. In forward lean of body, vibratory stimulations to TA reduced the COP sway area. During backward lean of body, vibratory stimulations to TS reduced the COP sway area. When the subject was tilted right, vibratory stimulations to left plantar zone reduced the COP sway area. During left lean of body, vibratory stimulations to right plantar zone reduced the COP sway area. Thus, the influence of vibratory stimulations to leg muscle and plantar zones differed significantly depending on the lean of body. We suggest that the vibration stimuli from leg muscles and plantar zones could be selectively used to help maintaining postural balance stable.

The purpose of this study was to analyze the effects of vibratory stimulus as somatosensory inputs on the postural control in human standing. To study these effects, the center of pressure(COP) was observed while subjects were standing on a stable and an unstable support with co-stimulated mechanical vibrations to flexor ankle muscles(tibialis anterior tendon, achilles tendon) and two plantar zones on both foot. The COP sway measurement was repeated twice in four conditions: (1) with visual cue and vibration, (2) without visual cue and vibration, (3) with visual cue and without vibration, (4) without visual cue and with vibration. The calculated parameters were the COP sway area and the distance, the median frequency and the spectral energy of COP sway in three intervals $0.1{\sim}0.3,\;0.3{\sim}1,\;1{\sim}3Hz$. The results showed that vibratory stimulus affect postural stability. The reduction rate of the COP sway with vibratory stimulus were higher on the unstable support because the effect of postural stability increases when afferent nervous flow is more activated by vibration on unstable support. If unclear visual or vibratory information is received, one type of information is compared with the other type of sensory information. Then the input balance between visual and vibratory information is corrected to maintain postural stability. These findings are important for the rehabilitation system of postural balance control and the use of vibratory information.

본 연구의 목적은 숙련된 골프선수들의 골프 스윙동작 시 상이한 무게중심 변환 형태가 존재하는지 그리고 만약 이 상이한 무게중심 변환 형태가 존재한다면 어떤 형태로 나타나는지를 알아보고자 하였다. 본 실험을 위해 13명의 남자 대학 엘리트 골프 선수들을 대상으로 드라이버를 이용한 스윙을 실시하게 하였다. 수직 지면 반력과 압력중심 이동 패턴을 측정하기 위해 지면반력기 2대와 스윙 동작 시 critical event 설정을 위해 1대의 고감도 비디오 카메라를 사용하였다. 또한 스윙 결과로 나타나는 비거리, 클럽헤드 속도를 측정하기 위해 스윙 분석기를 이용하였다. 피험자 간 상호 비교를 위해 측정된 수직 지면반력 성분은 몸무게를 이용하여 표준화하였고 압력중심은 어드레스시의 압력중심을 원점으로 재 계산하였다. 또한 임팩트 시 측정된 좌우 수직 지면반력 성분을 이용하여 두 가지의 상이한 스윙 스타일로 구분하였다. 연구결과 8명(62%)의 피험자에게서 좌측 수직력 성분이 상대적으로 높은 전족(FFS) 스타일임이 밝혀졌고 5명(38%)은 그 반대인 리버스(RFS) 스타일임이 밝혀졌다. 이 전족 스타일은 대부분의 골퍼들이 선호하고 또 그렇게 하여야만 한다고 믿고 있는 스윙방식이다. 이와 반대인 리버스 스타일은 코치들이 금기시 하는 스윙의 형태로서 초보자, 즉 비숙련 자에게만 나타나는 전형적인 스윙형태라고 인지되고 있다. 하지만 이 두 가지 스윙 스타일이 초보자가 아닌 숙련된 골프 선수들에게서도 실제 존재한다는 것이 본 실험 결과로 나타났다. 평균 압력중심 이동 패턴은 전후축 방향의 경우 RFS 스타일 그룹이 RFS 스타일 그룹에 비해 압력중심 이동이 크게 나타났고 좌우축의 경우에도 RFS 그룹이 FFS 그룹에 비해 압력중심 이동이 크게 나타났다. 특히 임팩트 시 압력중심의 위치가 FFS 그룹은 전족 근처에 있는 반면 RFS 그룹은 후족(rear foot)에 위치하여 두 스윙 스타일의 차이점을 분명하게 보여주었다. 따라서 비록 이 RFS 스타일이 대부분의 코칭 이론과는 상반되는 무게중심 이동 패턴을 보여주었지만 이 스윙 스타일이 잘못된 것이 아닌 실제 존재하는 하나의 스윙 스타일로 인식하여 스윙 지도 시 이에 알맞은 적절한 교습법을 마련해야 할 것이다.

This study aims to analyze the current situation of and issues in the structure of urban neighborhood parks and park facility installation in cities in Gyeonggi-do. Then, based on its findings, plans to improve the space structure of the parks were examined and suggested to raise the city environment improvement function and green area base function of urban parks and fully satisfy users' needs for pleasant rest, recreation and cultural activities. The findings showed that, within parks, the area of grass where access was restricted reached about 24.4% in average. In other words, only 75.6% of total park area could be freely used by park visitors. As for an improvement plan, the grass area where access is limited may be converted into a gras area that can be freely used to raise the park use area, which currently stands only at 75.6%, to 100%. The result of cross analysis through Chi-Square Test regarding lawn use as well as regarding (dis)agreement with reduction of lawn, based on the investigation of cognition, showed a significant agreement of park users with reduction of green areas. Therefore it is considered that lawn space must be reduced according the result of the analysis, to set up plans for facility space that would meet the desires of users. The analysis of user behaviors revealed that many of them used square spaces and walks; therefore it is considered that re-structuring of space is necessary according to local characteristics. This study also made some policy suggestion. urban parks must be a base of city green areas to counter climate changes. When developing a park creation plan, a user demand survey must be conducted in advance. In addition. grass construction methods should be improved to tolerate foot pressure.

Objective: This study aimed to investigate the differences in skiing time and vertical ground reaction force (vGRF) between the basic parallel turn and short turn. Method: Eleven alpine ski instructors (age: $28.73{\pm}4.29yrs$, height: $172.36{\pm}6.30cm$, body mass: $71.45{\pm}9.16kg$, career: $11.09{\pm}2.70yrs$) participated in this study. Each skier was asked to perform a basic parallel turn and short turn on a $16^{\circ}$ groomed slope. A foot pressure measurement system was used to measure the skiing time and vGRF under the three plantar regions (forefoot, midfoot, rearfoot). Results: Skiing time decreased significantly in all three phases during the short turn (p<.05). In the initiation phase, the vGRF showed a greater decrease on the midfoot and rearfoot during the short turn (p<.05). In the steering phase 1, the vGRF showed a greater increase on the forefoot and decreased on the midfoot during the short turn (p<.05). In the steering phase 2, the vGRF showed a greater increase on the forefoot and rearfoot during the short turn (p<.05). Conclusion: Our findings proved that the skiing time and vGRF changed during the short turn. Consequently, we suggest that recreational skiers should decrease the skiing time of the steering phase compared to that of the initiation phase and increase the vGRF on the forefoot and rearfoot in the steering phase.

The purpose of this study was to compare the balance and gait between fallers and non-fallers in elderly. A brief questionnaire was used to obtain the fall history. Twenty-seven women subjects were evaluated in this study. Eleven subjects and a mean age of 84.5 years (SD=4.6) were designated as the faller group. Sixteen subjects and a mean age of 80.3 years (SD=5.3) were designated as the non-faller group. The fall-related factors (mental status, balance, range of motion and muscle strength of lower extremity, sensation of foot, and cadence, walking velocity, stride length) were compared between faller group and non-faller group and measured. The results showed that faller group had significantly less range of motion of the hip flexion and knee extension, and strength of the knee extensor and ankle dorsiflexor and plantar flexor than non-faller group. The scores of the Functional reach test and One leg standing were significantly less in faller group than in non-faller group. Faller group showed less walking velocity and stride length compared to non-faller group. However, there was no significant difference in cadence during comfortable waking and fast walking between two groups. There were no significant differences in pressure, position sensory between two groups. These results suggest that exercise for improving the flexibility, muscle strength of the lower extremity and balance may be useful strategies to prevent fall in elderly. Further studies are needed to identify which specific factors are related to fall in the elderly population.

This paper presents a case of community participatory neighborhood park design. The site, Yangji park, is located in Sandang-dong, Dongjak-gu, Seoul and the area is about 1,870m. Neighborhood park is defined as an outdoor space which is close to people´s home and is considered to be their own, because of the residents´ collective responsibility, family association, and frequent shared use. It is a place for pleasant rest area for community, sharing a sense of nature and retaining a sense of tradition and culture which is disappearing in a city. It is related to the daily life of the people near the site and becomes a place to let the community increase dialogue and understanding between people. On the other hand, participatory design is a design in which people participate in the design process. Thus people can understand the project well, present their opinions better, and reconcile conflicts between the different interests of people. This design applied a community participatory design method to design a neighborhood park. The major strategies for participatory design were ´workshop´, ´card game´, ´walking site´, ´interview´, and ´questionnaire´. Eight workshops were performed for the participation design. The major spaces and facilities elected by participants were the ´main entrance plaza´, ´entrance symbol space´, ´children´s ´playground´, ´multipurpose sport ground´, ´grass land´, ´foot-pressure area´, ´spaces symbolizing a rock mountain and an old well´, ´space for youth´, ´a pavilion´, etc. From this selection, design concept alternatives were generated by participants. The aster plan was developed from these design alternatives with the help of landscape architects. It was revised by ist visits and community discussions. People were also involved in the construction process and left their own works, such as hand prints, on the site. After construction, residents continued to maintain the park by themselves. As a result, It was found that participatory design was very effective for people´s satisfaction and sustainable park management. By involving people more in the process they developed a sense of community, a sense of ownership, and attachment to the place. In conclusion, it is suggested that we need to develop an effective people´s participation method to Korean society.
