전준혁,Yonggi Kim 한국우주과학회 2019 Journal of Astronomy and Space Sciences Vol.36 No.3

This paper presents at the characteristics of publications in the Journal of Astronomy and Space Sciences from 1984 to 2018. Since its first publication, a total of 1,113 papers (~35 volumes) have been published up to December 2018. While the space astronomy field has made up a large portion of the total number of papers, the number of annually published papers in this field is decreasing. In contrast, the number of papers in the space environment field has been showing an increasing trend since 2013, accounting for more than 30% of the annual publications. The participation rate of foreign researchers has been maintained at greater than 20% since 2012. Despite the decrease in the number of paper per year, there are positive developments including sustained foreign researcher participation at greater than 20% and improvements in the impact factor. We believe that JASS has the potential to enter the distinguished level of international academic journals following a well developed future road map.

Purpose: The purpose of this study was to compare and analyze the dynamic balance ability and whole bodymuscle function of field hockey players. Methods: The subjects consisted of 12 university soccer players and eight field hockey players. The anterior,posteromedial, and posterolateral reach directions dynamic balance ability of both feet for the two groupswere determined using the Y-balance test kit. Each hand-push, each hand-pull, upper body-push, upperbody-pull, trunk rotation, lower body-push, and lower body-pull were measured for the two groups, usingthe smart muscle testing device. Results: For the Y-balance test, soccer players scored significantly higher than field hockey players forleft-posterolateral (p=0.024). Whole-body muscle function measures showed that field hockey players scoredsignificantly higher than soccer players for the right hand-push (p=0.002) and left hand-push (p=0.035). Conclusion: The results of this study showed that soccer players frequently shoot and dribble with their leftleg as a stepping foot, and the dynamic balance ability of the left-posterolateral is dominant due to theactivation of the tibialis anterior muscle used in the stepping foot. In addition, in the case of field hockey,due to the use of a hockey stick, , the muscle strength of the right hand-push and left hand-push is dominantdue to the adaptation of the muscles to the pushing force of the upper body, which is mainly used inmovements such as dribbling, passing, and shooting.

We report the results of our study for ascertaining whether Ganui-dae built in the Josen Dynasty actually performed an astronomical role or not. The Ganui-dae was the first astronomical structure built as a part of the state astronomical undertakings by King Se-Jong. Our analysis was based on the Annals of the Joseon Dynasty. At first we extracted the records regarding Ganui-dae from the Annals of the Joseon Dynasty and then classified them under six heads according to their astronomical meaning and historical significance. From this analysis we found that the Ganui-dae performed the actual astronomical role. In addition, the provisional offices and peoples mentioned in the records show the astronomical correlation. Generally, when taking into account the functional side of the records, the Ganui-dae was related with the observation. Therefore, the Ganui-dae was the space for the astronomical activity. In conclusion, the Ganui-dae was built for the purpose of the astronomical activity.

Canine model of ischemic stroke with autologous thrombus in three dogs; Magnetic resonance imaging features and histopathological findings

Ischemic stroke is the most common type of stroke in humans. The purpose of this study was to evaluate the di- agnostic value of magnetic resonance imaging (MRI) in a canine model of stroke. Ischemic stroke was induced by us- ing prepared autologous thrombus. The dogs were placed in lateral recumbency on the operation table and the cervical area of each dog was sterilized by using alcohol. After mak- ing a cervical incision, the common carotid artery and inter- nal carotid artery (a branch of the common carotid artery that supplies an anterior part of the brain) were exposed. A 200 µL injection of the autologous thrombus prepared 24 hr prior to surgery was delivered with a 20 gauge venous catheter through an internal carotid artery. After successful delivery of the autologous thrombus, the venous catheter was removed, and the cervical incision was sutured. Neuro- logic signs including generalized seizures, tetraparesis, and altered mental status, were observed in all 3 dogs after in- duction of ischemic stroke and the signs manifested immedi- ately after awakening from anesthesia. T1- and T2-weighted images and fluid-attenuated inversion recovery (FLAIR) images of the brain were acquired 1 day before and 1 day after surgery. On the day following ischemic stroke induc- tion, MRI revealed multifocal lesions in the cerebral cortex and subcortex such as T1 hypointensity, T2 hyperintensity, FLAIR hyperintensity, and diffusion-weighted hyperinten- sity in all 3 dogs. Upon postmortem examination, ischemic lesions were found to be consistent with the MRI findings and they were unstained with 2% triphenyltetrazolium chloride. Histologic features of the earliest neuronal changes such as cytoplasmic eosinophilia with pyknotic nuclei were identified. Neuropil spongiosis and perivascular cuffing were also prominently observed at the infarcted area. The present study demonstrated the features of MRI and histo- pathologic findings in canine ischemic stroke models.

샹탈 애커만의 <잔느 딜망>을 중심으로 살펴본 슬로우 시네마의 논점들

전준혁 한국예술교육학회 2023 예술교육연구 Vol.21 No.3

Chantal Akerman's "Jeanne Dielman," released in 1975, is a quintessential example of slow cinema, characterized by its slow pacing, extended durations, and a decentered temporality. It overturned the traditional narrative plot structure of films and enabled a transition into a counter-narrative bodily cinema. Influenced by the 1960s American avant-garde film movement and incorporating formal strategies from directors such as Andy Warhol and Michael Snow, Akerman created a unique film that integrated her personal experiences within the structural rules of cinema. The narrative progression borrowed from structural cinema in Akerman's work is the "repetition, anticipation, contrast, and overall rhythm" that fractures the monotonous repetition of everyday life, creating unexpected ruptures. The provocation of unforeseen events emerging from monotonous repetition is the source of narrative tension in "Jeanne Dielman," as it presents the tactile materiality of time within the film. The everyday gestures captured in real-time by the film break down the boundaries between what is reproduced by the film and what is presented before the camera, resulting in a discordant and am- biguous narrative. The fixed camera presenting gestures and objects, the flowing time itself, all be- come a construction of a non-causal, democratic coexistence of time and a decentered temporality within an extended duration. This study aims to examine the temporal significance of "Jeanne Dielman" and discuss the issues raised by slow cinema within its cinematic, social, and political con- texts, presenting them as a single question.

제지슬러지소각재 및 킬레이트제 활용 간접탄산화 방법을 통한 이산화탄소 저장 및 탄산칼슘 생성

전준혁,김명진,Jeon, Junhyeok,Kim, Myoung-Jin 한국자원리싸이클링학회 2019 資源 리싸이클링 Vol.28 No.3

In this study, we conducted experiments to store $CO_2$ and produce $CaCO_3$ through indirect carbonation using paper sludge ash (PSA) and three chelating reagents (fumarate, IDA and EDTA). Fumarate and IDA used as solvents could facilitate the indirect carbonation reaction to store more $CO_2$ than water. When 0.1 M fumarate and IDA were used, $CO_2$ storage was 63 and $89kg-CO_2/ton-PSA$, respectively, and $CaCO_3$ yield was 144 and $202kg-CaCO_3/ton-PSA$. For the case of EDTA, however, the carbonation was hardly progressed. As either the concentration or Ca-ligand stabilization constant of each chelating reagent increased, the calcium extraction efficiency from PSA increased. In addition, the carbonation efficiency was influenced by the Ca-ligand stabilization constant. As the Ca-ligand stabilization constant increased, more calcium could be extracted from the PSA. With the constant larger than that of $CaCO_3$ ($10^{8.35}$), however, the carbonation reaction was not proceeded.

영화의 움직임과 시간, 서사구조에 대한 연구- 벨라 타르의 <사탄탱고>를 중심으로

전준혁 한국영상제작기술학회 2022 영상기술연구 Vol.- No.39

If the modernity of the movie started from relieving the heavy burden of narrative and directly thinking about time, Béla tarr can be seen as an artist and philosopher who embodied the time-image in the body and landscape. <Sátátangó> is a masterpiece of that Tarr's radical ideas of cinematic form achieved from his stubborn effort. In the film, he succeeded in breaking the existing frame of thought and creating a new thought-image through the extreme duration of shots, the movement of slow-moving cameras, the structural completion of circular narratives form, poetic dialogues, meteorological expressions, and distance that obscures the represented reality. The contradictory themes of “human dignity” and “degradation of humanity,” which are repeated in Béla tarr's films, were born as modern fables with strict formal structures and sophisticated skills to materialize time through the absence of narratives. His works have a seasonality that returns repeatedly on a single theme. From the first work “Family Nest” to the last work “The Turin Horse,” the characters in desperate situations move forward with hope of improvement, but eventually return to a more desperate ending than the first. The characters in the film are the ones who fall into the trap. Allegorically textured figures with the characteristics of “madman”or “idiot” are isolated from the community and have an “outside view.” They are peepers. They are those who watch over windows, behind walls, in front of desks, and in a dark shadow, as communities in crisis fall for false promises or fall for themselves. As a result, however, they are also forced to be embroiled in the fate of corruption. Most prominent thing in <Sátátangó> is longtake shots that maintain a long duration. A camera that captures the body of a person and its movement, the arrangement and condition of things, and changes in light and weather in real time delays the narrative and imprints the image at the point where the material and time meet. This is the moment when the time-image proposed by Gilles Deleuze as a dividing point for modern films is expressed. Slow-moving cameras provide plenty of time for every detail that takes place within the screen. <Sátátangó>'s camera moves slowly as if floating in a spatiotemporal continuum, connecting space and time, and portraying the body and object on an equal footing. This slow pace draws attention to the body, matter, and time where the narrative stops and creates a new space for thought outside the narrative. <Sátátangó> is an alternative to traditional films that use the fantasy provided by the story to paralyze the audience, allowing them to vividly experience what the world in the movie is like, live in it, and invite them to the film's autonomous thinking-possibility.

하악골 전돌증 환자에서 하악지 시상분할골절단술후 금속고정판의 조기제거 및 기능운동이 턱관절장애에 미치는 영향

전준혁,김여갑,류동목,이백수,오정환,권용대,윤병욱,Jeon, Joon-Hyuk,Kim, Yeo-Gab,Ryu, Dong-Mok,Lee, Baek-Soo,Oh, Jung-Hwan,Kwon, Yong-Dae,Yoon, Byung-Wook 대한악안면성형재건외과학회 2005 Maxillofacial Plastic Reconstructive Surgery Vol.27 No.6

Purpose: The effect of orthognathic surgery on the temporomandibular dysfunction has been controversial. The purpose of this study is to prove statistically that early removal of fixation plate at postoperative 2 weeks with active exercise of mouth opening could relieve preoperative temporomandibular dysfunction and reposition of temporomandibular joint. Patients and Methods: All 28 subject patients underwent mandibular setback with BSSRO in Kyunghee medical center by one surgeon. The fixation plates used for rigid fixation were removed at postoperative 2 weeks and we had the patients excercise active mouth opening with intermaxillary rubber rings for the guiding proper postoperative occlusion. Temporomandibular symptoms were checked and radiographs were taken before surgery, within a month after surgery, six to twelve months after surgery respectively. Results: The temporomandibular dysfunction symptoms were relieved after the surgery and the condyle was displaced inferior-posteriorly immediate after surgery and repositioned toward its original position during follow-up periods. Conculusion: Orthognathic surgery may benefit temporomandibular joint dysfunction by obtaining a postoperative stable occlusion and more physiologic neuromuscular function. The early removal of fixation plates after BSSRO could reposition the temporomandibular joint to physiologic position and relieve the symptoms of temporomandibular dysfunction by permitting movement of proximal segment.
