환형 연소기 시스템에서 비연소 3D 음향장 해석

임재영,김대식 한국추진공학회 2017 한국추진공학회지 Vol.21 No.6

The current study has developed an in-house 3D FEM code in order to model thermoacoustic problems in an annular system and compared the acoustic field calculation results with measured ones from a benchmark combustor. From the comparison of calculation results with the measured data, the current acoustic code could successfully capture the various acoustic mode found in the annular system. In addition, it was found that the transverse waves in the combustor were strongly affected by the nozzle acoustic impedances, as well, the pressure distributions were closely related with the combustor acoustic pressure field. 연구에서는 환형 시스템에서 열음향 문제를 모델링하기 위하여 자체 3D 유한요소해석을 모델 개발을 통하여 음향장을 해석하였고, 다양한 음향 모드를 벤치마크 연소기의 실험 결과와 비교/검증하였다. 비교 결과, 본 해석에서 사용된 음향장 해석 코드는 환형 시스템에서 실험으로 계측된 다양한 음향 모드들을 예측하는데 성공하였다. 또한 연소실의 횡방향 모드는 노즐의 음향 경계 조건의 영향을 크게 받게 되고, 노즐에서의 압력 분포 역시 연소실의 압력장과 밀접한 관련이 있는 것으로 나타났다.

운동이 약이다: 의학은 핵심적 치료 도구인 운동을 어떻게 끌어안아야 하는가?

임재영 대한의사협회 2024 대한의사협회지 Vol.67 No.9

Background: As chronic diseases and the aging population increase, exercise is becoming more and more essential along with medical treatment for recovering and maintaining individuals’ physical health. Furthermore, the demand for exercise-based interventions in this context is growing. Although most healthcare professionals recognize the effectiveness and necessity of exercise, the “Exercise is Medicine” initiative has not been established in clinical settings. We aim to discuss the effectiveness and importance of exercise in the treatment and management of diseases and how exercise should be considered a key therapeutic tool in medicine. Current Concepts: Exercise-related mechanisms and their influence on body structure and function should be considered in disease management. It is necessary to understand these interactions and monitor their effects on the entire body. During recovery after an injury, exercise rehabilitation is provided as program customized according to the phase and function levels, the clinical pathway of which is feasible and effective. Exercise programs for maintaining the functioning and physical and mental health of people with disabilities should be developed by considering individuals’ functional levels, disability types, and conditions. Correct posture, microbreaks, and regular exercise are key to managing musculoskeletal pain. Discussion and Conclusion: To ensure the effectiveness of the “Exercise is Medicine” initiative, exercise should be included in the National Health Insurance System after clarifying the indications and clinical effectiveness of exercise therapy and defining specific procedures. Furthermore, increased awareness and changes in the attitude of healthcare professionals and patients toward exercise are necessary. It is now time for the medical community to ponder over and pool its wisdom on how to adopt exercise as a key therapeutic tool.

한라산의 신성성(神聖性)에 대한 연구

임재영 제주학회 2024 濟州島硏究 Vol.62 No.-

제주 섬의 중심이자 근간인 한라산은 오랜 시간 동안 신성성을 내포한 신앙의 대상이자 장소로 여겨져 왔다. 한라산의 신성성을 규명하는 것은 그 문화유산적 가치를 밝히는 일과 다름없다. 이 연구에서는 한라산의 신성성을 산신과 수호신, 신들의 거처, 신들의 탄생지, 그리고 신성하고 영험한 공간으로 구분하여 각각을 고찰하였다. 한라산은 예로부터 신적 숭배의 대상이었으며, 비, 바람, 구름을 일으키는 초월적 존재로 인식되었다. 조선시대에 한라산은 제주를 수호하는 신격으로 예우를 받았고, 전설적인 삼신산의 하나인 영주산이라는 별칭도 얻었다. 화산폭발로 형성된 정상 분화구의 독특한 경관은 신선사상과 결부되어 신선의 거처라는 특징적 요소가 강화되었다. 한라산에서 탄생한 신들은 마을을 관장하는 무속신앙의 당신으로 좌정하였다. 지배층에서는 유교적 제례인 산신제를 거행하였으며, 민간에서는 한라산에서 솟아난 당신에게 의지하여 마을과 개인의 안녕과 풍요를 소망하였다. 또한, 수행과 기도, 득도를 하는 신성하고 영험한 장소인 한라산에서 불교문화가 번성하였고 무속신앙이 행해졌다. 한라산의 신성성을 탐구하는 것은 제주의 문화유산적 가치를 더욱 깊이 이해하는 데 중요한 의미를 지니며 자연과 공존하는 측면에서 산 숭배를 새롭게 조명할 수 있다. Hallasan Mountain, the heart of Jeju Island, is revered for its sacredness and cultural heritage. This study explores its role as a mountain god, guardian deity, divine dwelling, birthplace of gods, and sacred space. Historically, Halla Mountain was worshipped for controlling weather and honored as a guardian during the Joseon Dynasty, earning the title Yeongju Mountain. Its volcanic crater linked it to Taoist immortals. Gods from Hallasan Mountain became key figures in local shamanistic practices. Confucian rites and Buddhist practices flourished here. Understanding Hallasan Mountain's sacredness from a perspective of natural harmony is essential for appreciating its cultural significance.

제주 오름의 인문경관에 대한 고찰 -공동묘지를 중심으로-

임재영 한국사진지리학회 2022 한국사진지리학회지 Vol.32 No.2

Oreums, volcanic bodies, along with Halla Mountain are unique landscape resources of Jeju. Tombs in an oreum are found everywhere throughout Jeju and they symbolize the identity of Jeju people who live relying on an oreum and are buried there after they die. Common cemeteries were built in oreums according to the Act of a tomb, crematorium, burial and cremation control under the rule of Japanese imperialism. At first, Jeju people were hesitant to bury their ancestors in a common cemetery. As time went by, after the 1970s they changed their mind and were in the business of burying their ancestors in a common cemetery because of the high cost and the legal regulation of burying in private graveyards. A lot of tombs in oreums formed its unique landscape and the space of life and death was separated there. There are 25 oreums where common cemeteries were built. Jeju people mostly buried their ancestors in a nearby oreum because they had to think about the easiness of a funeral. Common cemeteries a re m anaged b y the n earby v illages and its residents use an a ssigned area usually for f ree. The m ain factors of common cemeteries’ being built seem to be Japanese coercion, proximity, the effect of Fung Shui and the protection of farmland. Unlike other tombs, common cemeteries in oreums have no sandam, stones surrounding their tomb, in consideration of its size. Or there is simplified sandam using cement instead of stones to distinguish boundaries. This study is meaningful in that it is an attempt to examine the humanistic landscape of common cemeteries in Jeju’s Oreums.

상모(象毛)에 관한 연구

임재영 漢城大學校 2002 論文集 Vol.26 No.1

This study aims at viewing the origin, transition and uses of Sangmo decorated with red, thin feathers, based on old books. It can be concluded that Sangmo had been used for the military purpose, being found among the military articles including Jenrip(felt-het), Tugu(helmet), saddle, flag, spear and Mo. Sangmo came from ‘feather ornament’ and was developed into the round form of red feathers. Therefore it Has the same meaning with Sakmo-feathers with which a spear was decorated. There are two opinions about the origin and transition of the term, Sangmo. The one is that the original was Sakmo but has changed into Sangmo owing to pronunciation-related problems. The other is that Sangme has been changed into the form similar to Sakmo, a round-typed feather ornament with which a spear was decorated. Sangmo had been used for decorating Jenrip, Tugu, horse ornaments, flag, spear, Mo and the hat of a farmer's folk band all through Chosun-Dynasty and recorded only as one of the importing articles from China in the Chosun-wangjo Shil-rok Especially Sangmo was included among the list of presents which Chinese messengers brought for Chosun dynasty kings. and Chosun dynasty also brought for Japanese kings. During Chosun-dynasty Sangmo had a great importance as military signals, mere decorations and one of importing articles as well as presenting ones. Each Sangmo didn't have a specific figure and usage. However, it had been changed into the form of a special play-Sangmo Dolrigi being used as a hat of a farmer's folk band. It was also used in order to show off the motional beauty when players were spinning their heads in the instrumental music of peasants.
