Mediastinal emphysema, also referred to as pneumomediastinum or Hamman's syndrome, is defined as the presence of air or gas within the fascial planes of the mediastinum. Superior extension of air into the cervicofacial subcutaneous space via communications between the mediastinum and cervical fascial planes or spaces occurs occasionally. The mediastinal air may originate from the respiratory tract, the intrathoracic airway, the lung parenchyma, or the gastrointestinal tract. The presence of air in the mediastinum may be spontaneous, iatrogenic or due to penetrating trauma. Pneumothorax is defined as the presence of air or gas within the pleural cavity. A pneumothorax can occur spontaneously. It can also occur as the result of a disease or injury to the lung or due to a puncture to the chest wall. Pneumomediastinum and pneumothorax is a rare complication of head and neck surgery. Nevertheless, when it occurs, it is usually considered to result from direct dissection by the air at the time of injury or of surgery. Most of the cases of pneumomediastinum and pneumothorax that have been described in the oral and maxillofacial surgery literature result from air dissecting down the fascial planes of the neck. The authors report a case with subcutaneous emphysema, pneumomediastinum and pneumothorax after orthognathic surgery.

Introduction: In a surgery of the oral cavity, nasotracheal intubation is often carried out to secure the surgical field. By passing a tracheal tube through the nasal cavity to the pharynx, the nasotracheal intubation can lead to complications that do not occur with oral intubation, such as nasal bleeding and submucosal aberration etc. The purpose of this study is to examine the method of CT evaluation and pretreatment for a safe nasotracheal intubation. Materials and Methods: Among 30 patients who orthognathic surgery was performed at Chung-Ang University Hospital during the period August 2009 to October 2009, 30 patients were included. The 30 patients were divided into two groups; 15 patients intubated with CT evaluation with pretreatment, and the other 15 patients intubated with no pretreatment. We evaluated nasal bleeding of the two groups during nasotracheal intubation. Results: CT evaluation with pretreatment group had a significantly lower incidence of nasal bleeding than the group with no pretreatment. Conclusion: CT evaluation with pretreatment helps to minimize nasal bleeding during nasotracheal intubation.

암반발파는 광업, 터널공사, 지하 구조물 구축 등 다양한 분야에서 활용되고 있으며, 특히 지하공간의 활용이 증가하면서 암반발파 기술이 더 중요한 역할을 하고 있다. 암반발파 시 발파공에서 발생하는 발파공의 압력은 파쇄도, 발파진동 등에 직접적인 영향을 미치는 변수이며, 폭약의 성능 평가 및 발파 결과 예측에 있어서 가장 중요한 매개변수 중 하나이다. 이와 같은 발파공 압력은 몇몇 연구자들에 의해 연구가 수행된 바가 있지만, 폭약의 종류, 폭약량, 발파조건 등 실험조건으로 인하여 비교가 어려운 실정이다. 본 연구에서는 발파공 압력센서와 관측공 압력센서를 제작하여 단일공 발파 시 발파공과 관측공의 압력을 측정하였다. 실험결과를 바탕으로 발파공 주변 압력 전파특성과 발파진동 전파특성에 대해 고찰하였다. Rock blasting is utilized in various fields such as mining, tunneling, and the construction of underground structures. The role of rock blasting technology has became increasingly significant with the growing utilization of underground cavity. Blast hole pressure, generated during rock blasting, is a critical variable directly impacting factors such as crushing and blast vibration. It stands out as one of the most important parameters for assessing explosive performance and predicting blasting effects. While blast hole pressure has been studied by several researches, comparisons are challenging due to variations in experimental conditions such as explosive type, charge, and blasting conditions. In this study, blast hole pressure sensors and observation hole pressure sensors were developed to measure pressure during single-hole blasting, The experimental results were then used to discuss the propagation characteristics of pressure around the blast hole and the corresponding blast vibration.

최근 연구시설 및 자원개발 등의 목적으로 지하공간 활용이 증가하고 있으며, 저심도 암반을 넘어 고심도 암반에 대한 개발이 증가하고 있다. 고심도 지하공간 개발은 높은 응력과 높은 온도 조건에서의 암반의 안정성을 고려해야 한다. 고심도의 경우 암반 구조와 불연속면의 상태 등이 안정성에 영향을 미칠 뿐만 아니라 지진 및 굴착을 위한 암반발파에 의한 지반진동 전파가 지하공동의 응력변화를 발생시켜 암반의 안정성에 영향을 미치게 된다. 발파공학 측면에서 지반진동을 예측하는 방법은 실측 데이터를 바탕으로 통계학적 회귀분석을 통한 경험적 회귀모형과 수치해석적 방법이 사용되고 있다. 본 연구에서는 단일공 발파에 의한 폭발압력 전파특성과 지반진동 전파특성에 대한 경험적 회귀모형을 획득하기 위하여 실험적 방법을 통해 연구를 수행하였다. Recently, the utilization of underground space for research facilities and resource development has been on the rise, expanding development from shallow to deep underground. The establishment of deep underground spaces necessitates a thorough examination of rock stability under conditions of elevated stress and temperature. In instances of greater depth, the stability is influenced not only by the geological structure and discontinuity of rock but also by the propagation of ground vibrations resulting from earthquakes and rock blasting during excavation, causing stress changes in the underground cavity and impacting rock stability. In terms of blasting engineering, empirical regression models and numerical analysis methods are used to predict ground vibration through statistical regression analysis based on measured data. In this study, single-hole blasting was conducted, and the pressure of the blast hole and observation hole and ground vibration were measured. Based on the experimental results, the blast pressure blasting vibration at a distance, and the response characteristics of the tunnel floor, side walls, and ceiling were analyzed.

播種期 移動에 따르는 麥酒麥 主要形質의 遺傳的 Parmeter 變化에 관한 硏究 : 播種基別-遺傳相關 및 表現型相關의 變化 Ⅰ. Changes in Genotypic and Phenotypic Correlations with Different Seeding Dates

金翰琳 제주대학교 1979 논문집 Vol.11 No.-

Genotypic and phenotypic correlations were estimated on 10 agronomic characters in 20 varieties of two-row barley (Hordeum disticbum L. emend Lamark)seeded 5 times with 15 day interval from October 16 on Jeju-do. The correlationships between characters were changed with the different seeding dates and the tendency of the change was not regular. Genotypic correlations between grain weight and the number of spikes, between grain weight and spike weight and between days to heading and days to maturity showed highly positive. The fluctuations in those correlations were not marked with different seeding dates. 1,000 grain weight was negatively correlated with most other characters in genotypic correlation and the number of spikes with the number of grains per spike but correlation coefficients between those characters were not high. Phenotypic correlations between grain weight and spike weight and between days to heading and days to maturity were found significant on all the seeding dates, and the correlation between grain weight and the number of spikes on the first, the second, and fifth seeding time. Generally the coefficients of genotypic correlations were higher than those of corresponding phenotypic correlations.

돼지감자에 있어서 播種期에 따른 二品種의 實用形疾의 變化

金翰琳 제주대학교 1984 논문집 Vol.18 No.-

本 硏究는 3月 29日부터 4月 26日까지 7日 간격으로 돼지감자의 白色種과 赤色種을 播種하여 實用形質의 變化를 究明하기 위하여 遂行되었는데, 其 結果는 다음과 같다. 塊莖收量과 一塊莖重 및 地上部의 乾物重은 白色種이 赤色種보다 더 무거웠으나 塊莖數는 赤色種이 더 많았다. 파종기가 늦을수록 두 品種 모두 塊莖收量, 一塊莖量, 地上部乾物重 및 草長이 감소되었고, 파종기의 遲延에 따르는 塊莖收量과 一塊莖重의 減少程度는 白色種에서보다 晩生種인 赤色種에서 더욱 뚜렷하였다. 塊莖收量은 白色種에서는 一塊莖重 및 地上部乾物重과 正의 相關關係가 있고, 赤色種에서는 塊莖數, 一塊莖重, 乾物重 및 草長과 有意的인 相關關係가 있었다. 一塊莖重은 地上部乾物重 및 草長과도 두 品種 共히 相關關係가 있었으나, 白色種에서의 塊莖數는 다른 形質과 相關이 없었다. This study was conducted to clarify the changes in the characters of Jerusalem artichoke cultivars, the white and the red, which were planted with seven day intervals from March 29 to April 26 on Cheju island. The results obtained are summarized as follows; The white cultivar was higher in the tuber yield, and heavier in the weight of a tuber and the dry top weight than the red, but the number of tubers was larger in the red than in the white. As the seeding date was late, the tuber yield, the weight of a tuber, the dry top weight and the plant length decreased in the both cultivars. The decrease of the tuber yield and the weight of a tuber was more remarkable in the red than in the white with delaying seeding date. The tuber yield was positively correlated with the weight of a tuber and the dry top weight in the white, and with the number of tubers, the weight of a tuber, the dry top weight and the plant length in the red. The weight of a tuber had correlation with the dry top weight and the plant length in the both cultivars. There was no relation between the number of tubers and the other characters of the white.

병풀(Centella asiatica (L.) Urbain)의 栽培와 選拔에 관한 硏究 : 1. 병풀의 選拔에 관하여 1. On Selection of C. asiatica

김한림,박양문 濟州大學校 亞熱帶農業硏究所 1989 亞熱帶農業硏究 Vol.6 No.-

This Study was conducted to clarify the selection criteria in Centella asiatica collected in Cheju-do. Clone No. 16, No. 26 and No. 29 of 30 clones were desirable in shoot weight and other agronomic characters. The heritabilities for shoot weight, leaf length and leaf width were high, but those for the number of stems and the number of new shoots low. Genotypic and phenotypic correlation coefficients between leaf width and leaf length, between shoot weight and leaf width, between shoot weight and leaf length, and between shoot weight and the number of new shoots showed high positive value. There were significant environmental correlations between leaf length and leaf width, between petiole length and internode length, between shoot weight and leaf width, between shoot weight and leaf length, and between shoot weight and the number of new shoots. As a result, leaf width and leaf length were high in heritabilities and were highly correlated with shoot weight in genetics, so it was thought that these characters were useful selection criteria for shoot weight.
