Tomohiro Sawano,Hideto Kojima,Takanori Miyoshi,Kazuhiko Terashima 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8

In this paper, a power-assisted attitude control system, of which the purpose is to eliminate a worker’s burden and to support the operation for beginners, is presented. In previous studies, we already suggested a power-assisted system to control the horizontal and vertical axes. However, it did not deal with rotary motion. Therefore, we try to enhance the dimension of motion control in the assembling process because a system with three degrees of freedom (DOF) has limited workability. In this study, we proposed a novel power-assisted system that had a higher degree of freedom to achieve attitude control, and confirmed the effectiveness of this system experimentally.

CHARACTERIZATION OF THE MULTIPLIERS FROM Ḣ_r TO Ḣ_-r

Gala, Sadek,Sawano, Yoshihiro Korean Mathematical Society 2013 대한수학회보 Vol.50 No.3

In this paper, we will provide an alternative proof to characterize the pointwise multipliers which maps a Sobolev space $\dot{H}^r(\mathb{R}^d)$ to its dual $\dot{H}^{-r}(\mathb{R}^d)$ in the case 0 < $r$ < $\frac{d}{2}$ by a simple application of the definition of fractional Sobolev space. The proof relies on a method introduced by Maz'ya-Verbitsky [9] to prove the same result.

Study Design: Retrospective study.Purpose: This research aimed to assess the clinical outcomes of patients with traumatic cervical spine dislocation who underwent closed reduction employing our approach.Overview of Literature: Bedside closed reduction is the quickest procedure for repairing traumatic cervical spine dislocations; nevertheless, it also possesses the risk of neurological deterioration.Methods: For closed reduction, the patient’s head was elevated on a motorized bed, the cervical spine was placed at the midline, traction of 10 kg was applied, the motorized bed was gradually returned to a flat position, the head was lifted off the bed, and the cervical spine was slowly adjusted to a flexed position. The weight of traction was elevated by 5-kg increments until the positional shift was attained. Subsequently, the bed was gradually tilted while traction was applied again to return the cervical spine to the midline position.Results: Of the 43 cases of cervical spine dislocation, closed reduction was carried out in 40 cases, of which 36 were successful. During repositioning, three patients experienced a temporary worsening of their neck pain and neurological symptoms that enhanced when the cervical spine was flexed. Closed reduction was conducted while the patient was awake; nevertheless, sedation was needed in three cases. Among the 24 patients whose pretreatment paralysis had been characterized by American Spinal Injury Association Impairment Scale (AIS) grades A–C, seven patients (29.2%) demonstrated an enhancement of two or more AIS grades at the last observation.Conclusions: Our closed reduction approach safely repaired traumatic cervical spine dislocations.

THREE GEOMETRIC CONSTANTS FOR MORREY SPACES

Gunawan, Hendra,Kikianty, Eder,Sawano, Yoshihiro,Schwanke, Christopher Korean Mathematical Society 2019 대한수학회보 Vol.56 No.6

In this paper we calculate three geometric constants, namely the von Neumann-Jordan constant, the James constant, and the Dunkl-Williams constant, for Morrey spaces and discrete Morrey spaces. These constants measure uniformly nonsquareness of the associated spaces. We obtain that the three constants are the same as those for $L^1$ and $L^{\infty}$ spaces.

한ㆍ일 여대생들의 비만에 대한 인식 및 생활패턴 비교

김미옥(Mi-Ok Kim),Kayoko Sawano 한국식품영양과학회 2010 한국식품영양과학회지 Vol.39 No.5

본 연구는 한ㆍ일 여대생들의 비만정도 및 식습관 등에 관한 비교연구로 평균연령 약 21세에 평균신장 161 ㎝, 평균체중 54 ㎏을 나타내는 한ㆍ일 여대생을 대상으로 비만정도, 비만에 대한 인식 및 태도, 식습관, 운동습관, 그리고 생활습관에 대하여 조사하였다. 먼저 한?일 여대생들의 비만정도를 살펴본 결과, 한국여대생의 경우, 정상 체중의 경우가 56.4%로 가장 많았고, 저체중(27.7%), 과체중(9.9%), 비만(4.0%)그리고 극심한 저체중(2.0%)로 나타났으며, 일본여대생의 경우는 정상(52.9%), 저체중(23.6%), 과체중(15.5%), 비만(5.7%), 고도비만(1.6%), 그리고 극심한 저체중(0.8%) 순으로 나타나 유사한 경향을 나타내었다. 비만에 대한 인식 및 태도 면에서는 한국여대생들은 비만은 친구와의 관계를 어렵게 하고 공부나 운동에 지장을 주며, 친구 앞에서 자신이 없다는 질문에 대체로 그렇다는 답이 가장 많았으나 일본여대생의 경우는 그렇지 않다는 답이 가장 많이 나타났다. 또한 한국여대생은 비만이면 친구로부터 놀림을 당하고 비만이 아닌 사람보다 불이익을 받을 수 있다고 생각하는 반면에 일본여대생은 그렇지 않다고 답한 경우가 가장 많았다. 그이외에 비만은 심각한 건강문제를 발생시키고, 비만을 잘 관리하면 생활습관병에 걸릴 위험이 줄어든다는 문항과 비만 관리를 위해서 식생활을 조절할 필요가 있다는 문항에서는 한ㆍ일 여대생 간의 의견이 모두 유사한 경향으로 나타났다. 한ㆍ일 여대생들의 식습관 차이를 살펴본 결과는 한ㆍ일 여대생 모두 좋아하는 음식이 있을 때 과식하는 것으로 나타났다. 아침식사여부는 한국여대생의 경우는 거의 먹지 않는다(36.6%)는 답이 가장 많이 나왔고, 매일 먹는다는 24.8% 정도였다. 반면에 일본여대생의 경우는 약 48.0%가 매일 먹는다고 가장 많이 답하였고, 거의 먹지 않는다는 14.6% 수준으로 나타나, 일본여대생의 경우 한국여대생보다 비교적 아침식사를 잘 챙겨먹는 것으로 나타났다. 저녁식사는 한ㆍ일 여대생 모두 매일 먹는다는 답을 높게 나타났다. 또한 간식의 내용으로는 한ㆍ일 여대생 모두 비스킷류를 가장 많이 선호하는 것으로 나타났다. 그리고 식습관에 미치는 영향으로는 한국 여대생은 TV 광고(57.4%), 일본여대생은 부모님(47.2%)을 가장 많이 선택하였다. 또한 운동습관에 대해 알아본 결과는 모두 지속적으로 하고 있는 운동은 없는 것으로 나타났고, 1주일 동안의 운동정도는 한국여대생은 주 1회(34.7%), 일본 여대생은 없다(79.7%)가 가장 많이 나타났다. 또한 이렇게 운동시간을 답한 학생들의 운동하는 이유로는 한국여대생은 체중조절(53.5%)이 가장 큰 원인으로 나타났으며, 운동을 하지 않는 이유로는 귀찮아서(78.2%)가 가장 높게 나타났다. 그리고 생활습관 측면에서는 한ㆍ일 여대생 모두 대체로 유사한 경향을 나타내었으나, 다소 스트레스가 쌓였을 때 스트레스 해결방안으로 한국여대생은 친구와 수다떨기라고 답하였지만, 일본여대생은 음악감상 및 독서를 가장 많이 선택하여 한국여대생은 교우관계를 통한 스트레스 해결방안을 모색하지만, 일본여대생은 혼자서 해결할 수 있는 음악감상 및 독서가 많은 것으로 나타났다. 비만에 영향을 주는 생활패턴은 질병의 위험과 함께 건강을 유지해 나가는데 많은 어려움이 내재되어 있다. 본 연구에서는 한ㆍ일 여대생들의 생활패턴을 비교하여 여대생들의 비만에 대한 올바른 인식을 고취하고 바람직한 체중조절을 위한 방안 제시에 도움이 되고자 하였다. This study looked into the obesity status, recognition of obesity, attitude towards obesity, eating and exercise habits, and lifestyles of Korean (n=101) and Japanese (n=123) female college students. All students were 21-years-of age, with an average height of 161 cm and the average weight of 54 kg. Korean female students responded that obesity complicated friendships, and hindered study and exercise. Japanese students did not express these opinions. Both Korean and Japanese students tended to over-consume their favorite food. Korean students ate breakfast about 24.8% everyday, while 48% of Japanese students did; both regularly ate dinner. Snack preference was mainly biscuits. The factor most influencing eating habits were TV advertisement for Korean students (57.4%) and parents for Japanese students (47.2%). Once-weekly exercise was done regularly by 34.7% of Korean students but only 20.3% of Japanese students. The main reason for Korean students to exercise was weight reduction (53.5%), while 78.2% did not exercise because it was tiring. Korean and Japanese students had similar life styles, although stress relief in Korean students was sought through conversations with friends and by reading books or listening to music for Japanese students.

Estimation of environmental damage assessment in the shoreline after the NAKHODKA oil-spill using Geo-informatics

Kim, Sang Woo,Goto, Shintaro,Matui, Kouji,Shikada, Masaaki,Shikida, Asami,Sawano, Nobuhiro 대한원격탐사학회 1999 International Symposium on Remote Sensing Vol.15 No.1

The investigation of the amount of the ecosystem damage on the shoreline due to the NAHODKA oil-spill accident, which occurred in the Sea of Japan, was attempted by using geoinformatics. At first, it was assumed that symbolical vegetation's distribution could be specified in the coast in Ishikawa Pref. where the heavy oil was washed, and surveyed the regional distribution. Then, the presumption result of those environmental capacities was arranged by GIS. In addition, the amount of the ecosystem damage was presumed as cost necessary though a symbolical living thing for the retreat because of the base line by the heavy oil drifting ashore was recovered. By comparing the vegetation line and the surveying data which shows environmental capacity, the retreat areas of the vegetation were 1100-1200 ㎡. When the amount of damage on the ecosystem of the NAHODKA oil-spill accident was presumed based on the retreat area of this vegetation and the restoration cost, the amount of damage within Shioya beach which 150m in the surveying range became 2 to 2.5 million Yen. Because the extension distance from the Shioya beach to the Katano beach was about 3,500m, the amount of damage became about 46 to 65 million Yen. As a result of calculation for the amount of damage on the ecosystem of the NAHODKA oil spill accident, it was estimated approximately 1,400 to 2,000 million Yen in the shoreline of Ishikawa Pref., because the total extension of beaches in Ishikawa Pref. is about 110km.
