The prime goal of the present study was to analyse the occupation socialization process of a professional golfer using an ethnographic research. The seven study participants was chosen among the regular members and associate members of KPGA in Ulsan after explaining the purpose of the study. The study participants was interviewed in depth using unstructured pattern and half-structured pattern. I recorded the interview with the agreement of the study participants. Also, I collected the document data and checked the result of the interview with the study participants. Additionally, the study data was supplemented continuously through the interview because the experience of participants and the certainty of their interview was not clear at first. In terms of the material analysis, the analysis of content was interpreted progressively by the comparison analysis. For the ethicality and the honesty of the data, the experts’ conference verified continuously during the period of the study. Through the process of the study, the results of the study was came out as follows. First, the process of the way to become a professional golfer was that they came into the world of the golf naturally, realized the reason why they chose a golf, and thought that it was the chance to go to the high social class. The first stage was the beginning step to dream their future and to process the unusual occupation socialization. Also, to become a professional golfer, they recognized the necessity of internal change, had a time for a self-development, and tried to have a positive mind to being a professional golfer in order to change the public"s negative attitudes of a golf. Second, it was the stage that they had wanted to change their job because of unstable income, a family faud, and the difficulty of various situation about golf. The participants realized theirselves through recurrent training to become a professional golfer, a economic difficulty, and negative experience with injured body. Third, at this stage, the participants of the study got over the conflict of their occupation and adapted the reality of society through untiring efforts. In addition, they noticed if they were not changed, they would got into a trouble due to the rapid change of our society. They felt that it was worth to become a professional golfer, formed the social status and the occupational identity. Lastly, the study showed that the participants endeavored to success their lives as professional golfers on the basis of their experience.

본 연구의 목적은 소매틱스(Somatic) 프로그램을 적용하여 고등학생들의 자세인식과 통증의 변화를 분석하고 신체적, 심리적 변화과정을 탐색하는데 있었다. 연구대상은 서울시 소재 1개 고교의 학생 25명을 목적적으로 선정하였으며 학생들의 자세인식과 통증정도를 파악하였다. 이후 소매틱스 프로그램을 주 2회 1시간씩 총 4주에 걸쳐 8차시를 실행한 후 자료수집이 완료되었다. 자료분석 도구는 학생들의 자세 인식 분석을 위해 개방 설문지와 심층면담, 차시가 거듭됨에 따라 나타나는 심리, 신체적 변화를 파악하기 위해 학생일지가 이용되었다. 사전-사후검사에 따른 변화를 검증하기 위한 자료처리는 SPSS 18.0 통계 패키지가 이용되었으며 통계적 유의수준은 .05에서 설정되었다. 자료분석 결과는 아래와 같이 나타났다. 첫째, 소매틱스 프로그램은 학생들의 자세인식 변화와 통증개선에 긍정적 효과를 나타냈다. 둘째, 신체적 변화과정에서 호흡, 긴장, 통증 요인은 감소하였고 신체인지 능력이 높아졌다. 셋째, 심리적 변화과정에서는 심리적 안정요인은 감소하였고 자세인식, 집중력, 흥미요인이 증가하였으며, 그 중 자세인식 요인이 가장 많은 증가율을 나타냈다. 본 연구는 소매틱스 프로그램이 학생들의 자세인식과 통증개선에 효과적이며, 학생들에게 신체인지능력을 향상시킨다는 도움이 된다는 사실을 보여주었다. 따라서 소매틱스 프로그램이 학교 체육교육의 한 프로그램으로서 제공될만한 가치가 충분함을 나타내고 있다. 특히 다양한 자세문제와 기능적 불편함이나 장애를 갖고 있는 학생들에게 더욱 유용할 것임을 강조하고 있다. 아울러 본 기술연구는 자세교육의 중요성과 소매틱스를 활용한 실천적 자세교육의 중요성에 대한 인식제고와 실천의 장이 시급하다는 사실을 나타내고 있다. Purpose: The purpose of this study was to explore the high school students’ postural perspectives and pain. Methods: The subjects for this study were 25 high school students who purposively selected at A high school in Seoul metropolitan area. Before conducting somatics programs, pretest was applied to determine the students’ postural perspectives and pain. Somatics program was conducted two times a week through 4 weeks. Posttest was conducted after total 8 classes were completed. Somatics programs included total 9 items. PASW(Predictive Analytics Software) Statistics 18.0 program was utilized and statistical alpha level was set at .05. Chi-square analysis was used to determine students’ posture perspectives and t-test was conducted to determine the rate of pain through pre and post-test. Students’ diary and participation record were used to analyze students’ physical and psychological changes. Results: The results of this study shows that somatics program was positively effective to enhance students’ postural perspectives. Somatics also contribute to students’ pain reliefs. Students’ physical change was significantly showed in breathing, tension, and pain reliefs. physical awareness also improved. In psychological change, concentration, interest, and postural perspectives were notably improved. Conclusion: The study strongly suggests that somatics can be applied as a one of school physical education programs. It clearly will be benefited for the students who suffers various postural problems and functional ineffectiveness.

본 연구는 열풍 건조장치를 이용하여 음식물류 폐기물의 재활용 측면에서 음식물류 폐기물과 열풍(200℃, 250℃) 건조방식에 따른 운전시간별 건조특성을 평가하고자 하며, 또한 건조물질의 삼성분(수분, 가연분, 회분) 등 고형연료로서의 품질특성을 평가하는데 그 목적이 있다. 본 연구에 사용된 음식물류 폐기물은 B시 P사에서 채취하여 사용하였으며, 음식물류 폐기물과 가연성 물질의 균질 혼합 및 건조효율 향상을 위하여 비닐, 어패류 등 이물질을 제거하였다. 열풍 건조장치의 전체 크기는 W 1,360 mm × L 1,060 mm × H 900 mm, 열풍 건조장치의 조사강도는 1kW이며, 건조온도는 최대 300℃까지 조절할 수 있도록 제작하였다. 음식물류 폐기물 건조실험을 실시한 결과 열풍 (200, 250℃) 건조를 이용한 완전건조 (함수율10% 이하)시 최종 함수율 변화는 운전시간 각각 30분에서 8.5%, 25분에서 8.9%로 나타났다. 실험결과 음식물류 폐기물에 첨가물을 혼합하였을 경우, 음식물류 폐기물의 재활용 방안으로 열풍융합건조공정을 이용한 고형연료의 생산이 충분히 가능할 것으로 판단된다. The main objective of this study is on the development of a method for recycling food waste by using the inner-cycle Thermal air (200, 250℃) drying process, aiming to assess the quality of RDF(refuse derived fuel) in terms of its 3-component analysis (water content, ash content and combustible content). The food waste used in this research was collected at P Company located in B City. For homogeneous mixture of food waste with combustible materials and for better drying efficiency, foreign substances which were vinyl, fish and shellfish were removed. The size of the inner-cycle thermal air drying unit is 1,360 mm(W) × 1,060 mm(L) × 900 mm(H), and its projection intensity and frequency were 1 kW and 2,450 MHz, respectively. Also, unit was designed to control the drying temperature up to 300℃. As a result of the experiment, the food waste dried using the inner-cycle Thermal air (200, 250℃) drying process led to the final moisture contents of 8.5%, 8.9%, respectively, which levels were lowest for full harness (moisture content : less than 10%) and 30, 25min operating period. The result of an experiment, food waste was found to produce good quality RDF that met the quality standard. In sum, as a way for recycling food waste, the inner-cycle Thermal air drying process seems capable of producing RDF to the full extent.

The aim of this study was to interpret the structure and dynamics of a transfer shuttle system as a material supply device for small machine tools. The following conclusions were obtained by performing a structural interpretation of the material supply equipment with respect to workload and the dynamical interpretation of a flexible multibody carriage shuttle. When a 1,000-kg workload was applied to a fork lift, the safety factor was approximately 1.86. To conservatively assess the integrity of the structure, a 1,000-kg workload would be proper. In the case of a deflection of the fork system, the width increased with increasing time. The greatest deflection occurred at 5.5 s, which was the largest increase in the time point of the fork system.

강인한 그래프 SLAM을 위한 시각적 루프 클로징 평가 방법

변다솔(Dasol Byun),강수민(Sumin Kang),이승환(Seunghwan Lee) 대한전기학회 2021 대한전기학회 학술대회 논문집 Vol.2021 No.10

그래프 기반 SLAM 기술은 Front-end와 Back-end로 구성된다. Front-end에서는 노드와 엣지를 통해 그래프를 구성하고, Back-end에서는 루프 클로징 정보로부터 그래프를 최적화한다. 하지만 부정확한 루프 클로징 정보에 의해서 SLAM 결과가 크게 저하될 수 있다. 본 논문에서는 딥러닝 구조인 GoogLeNet을 이용하여 부정확한 루프 클로징 결과를 시각적으로 평가하고, 이를 통해 SLAM 정확성을 향상하고자 한다. 정확한 루프 클로징 및 부정확한 루프 클로징 결과들을 학습 데이터 셋으로 구성하였고, 이를 이용하여 GoogLeNet을 학습하였다. 학습된 네트워크는 SLAM Back-end와 연계되어 루프 클로징 정보로 인한 최적화 결과(지도 정보)를 평가하도록 설계되었다. 실험에는 공용 데이터 셋인 MIT CSAIL Building 데이터 셋이 활용되었고, 제안된 시각적 평가 방법을 통해 루프 클로징 적절성에 대한 판단이 정확히 이루어짐을 보였다.
