Causes of atelectasis under general anesthesia are tracheal foreign body, blood clot, aspiration of bronchial secretion, one-lung ventilation and relative predominance of parasympathetic system. N-acetylcysteine is mucolytic agent which improves the capability of sputum drainage. After administration of N-acetylcysteine, an increased volume of liquified bronchial secretions may occur. When cough is inadequate, the airway must be maintained open by mechanical suction. In case that is a mechanical block due to local accumulation, the airway should be cleared by endotracheal aspiration. A 49-year-old female was admitted for bilateral laparoscopic oophorectomy due to ovarian tumors. There was not any problem during a general anesthesia induction. After instillation of N-acetylcysteine into endotracheal tube, acute atelectasis was developed in right lower lung.

Palgongsan granite considered to be a rapid cooling shallow-level intrusion, exhibits textural and mineralogical changes from margin toward core. In petrochemistry it is characteristic of I-type granitoid representing calc-alkaline differentiation trend, which is discriminated active continental arc granitoid in tectonomagmatic environment. In Q-Ab-Or-An system norm compositions of the Palgongsan granite are plotted near low-temperature trough, and concentrated on the minimum melt curve (700℃). Palgongsan granite intruded and metamorphosed sedimentary rocks to hornfelses forming contact metamorphic aureoles (average 1.5 km width). Contact aureoles are divided into inner and outer zone, which are respectively biotite and chlorite zone, indicating albite-epidote hornfels facies. The mineral assemblages are chlorite-muscovite in chlorite zone and biotite-muscovite(-chlorite), epidote-chlorite, actinolite-chlorite and actinolite -epidote-chlorite in biotite zone. Metamorphic temperature is as low as to be estimated about 350℃ in chlorite zone and 400℃ or higher in biotite zone.

본 연구는 여대생의 다이어트 행동 및 심리적 변인간의 관계를 알아보려는 것이다. 이를 위해 가톨릭대학교 여학생 441명을 대상으로 설문조사를 실시하였다. 본 연구의 목적은 다음과 같다. 첫째, 여대생들의 다이어트 행동을 다각적인 면에서 살펴보는 것이다. 둘째, 다이어트 행동과 신체불만족 및 자존감의 관계를 탐색한다. 셋째, 다이어트의 극단성과 섭식장애의 관계를 당색한다. 이를 위해 다이어트 행동에 관한 설문지와 신체불만족 척도, 자존감 척도, 그리고 식사태도검사가 사용되었다. 먼저 다이어트 행동양상의 조사에서 전체 조사대상의 54 .4%가 다이어트를 하였으며, 다이어트집단 중 90.7% 는 다이어트가 불필요한 저체중자와 표준체중자였다. 또한 다이어트 집단 중 70 .4%가 무리한 다이어트를 하는 것으로 나타났다. 다이어트의 이유에 대해서는 주로 날씬함과 아름다움의 추구 및 옷맵시 등의 이유가 대부분이었으며, 다이어트 방법에서도 98% 가 식사조절을 사용하였는데 그 방법은 대개 끼니거르기, 절식 등의 무리한 방법이었다. 다이아트 결과에 대한 응답에서는 감량된 체중이 1개월 이상 지속되지 못하는 경우가 45.4%였고, 응답자의 41.9% 가 폭식의 식습관 형성을 다이어트의 부작용으로 보고하였다. 다이어트와 심리적 변인과의 관계에서는 먼저, 높은 신체불만족수준과 낮은 자존감수준은 다이어트 행동을 유발하며, 신체불만족이 높을수록 다이어트는 극단적으로 나타나는 것으로 밝혀졌다. 또한 식사 태도와의 관계에서, 다이어트를 극단적으로 하는 사람은 폭식이나 절식의 식습관으로 이어질 수 있으며 또한 섭식장애로 발전될 가능성이 있었다. 이 연구는 여대생들의 다이어트 행동의 심각성을 지적하며 이로 인한 섭식태도의 문제점 및 섭식장애 가능성을 살펴본데 의의가 있으며, 섭식장애 예방을 위한 올바른 다이어트 행동의 지도를 제안한다.

We are representing the equation of c???x'²by x²with degree of freedom n' and c???(x'²-b) by x²with degree of freedom n'. Also, approximation formulas of noncentral x'²can be represented by expansion method. The calculation of noncentral x'²is complicated when the degree of freedom is decimal point number. In this paper, we have attempted the numerical comparison of percentile points of the noncentral x'²with the correction term.

The purpose of this study is to investigate the general characteristics of modern library which was in a germinal stage at the opening period of Korea. The major findings of this study is summarized as follows. (1) Modern libraries which began to develop during the opening period of Korea were deeply rooted in the spirit of patriotism. After 1905, which was the year of so-called Korean-Japanese Protocal concluded under the Japanese military pressure, the patriotic enlightenment campaign against foreign penetration developed rapidly throughout the country. Accordingly, the movement for establishing modern library was carried out among advanced reformers. (2) The first modern school library was built in the private school of Wonsan established by the residents of Wonsan area. They believed that the best way to strengthen the national power to oppose Japanese penetration was to learn the Western culture and technology. (3) The first modern public library named The Central Library of Korea was originated by Oh Ha Young and his comrade in 1906. Included among these promoters of the library were Yun Chi Ho and Min Sang Ho, two persons who had experienced Western culture during their study abroad. (4) Pakmunkuk, the newspaper office of the government, had its own library in 1883 which was the first modernized special library in Korea. (5) Major factors which hindered the rapid growth modern libraries in the opening period are as follows; ① Lack of people's demand for the library. ② Limited scope of the publications(mainly school text-books) ③Poor financial conditions. (6) Japanese invasion in 1910 had broken the growing roots of modern libraries in formative stage

We propose the control chart to provide a more comprehensive scheme for detecting process mean shifts. In this papers, using the backpropagation, five samples are fed into the trained neural network to provide outputs ranging from -1 to 1. The main advantage of using neural network with control chart is that the neural network has almost no delay in detecting small and systematic patterns in the mean. Simulation results show that the performance of the proposed control chart using the neural network is quite promising.

The libraries of the various learning institutes in the Yi Dynasty may be categorized into types: 1)The Hyang-Gyo library(the public school libraries in rural districts) 2)The Sabu-Hankdang library(the public school libraries in the Capital) 3)The Sowon library(the libraries of private learning institutes) 4)The Jyon-Gyong-Gak library(the library of the Sung Kyun Kwan which was the highest learning institute in the Yi Dynasty) For the historical study of Korean libraries as well as its education and culture the Hyang-Gyo libraries hold an very important position, but undeservedly its study has been neglected. In this paper, the writer made an effort to grasp the various function of the Hyang-gyo libraries with its historical background

Although vallecular cyst is often asymptomatic and harmless to the patient, discovery of large vallecular cyst after induction of anesthesia is a potentially life-threatening problem for thepatient and provides for the anesthesiologist a challenge in airway management. We describe a case of difficult intubation where the laryngeal inlet was obscured by a large vallecular cyst that was discovered during induction of general anesthesia. A 47-year-old man presented for elective laparoscopic colecystectomy due to GB polyp. He had normal mouth opening and neck extension; no mass or distortions of the tongue or neck were observed. Anesthesia and paralysis were induced with 80 ㎎ propofol, alfentanil 0.5 ㎎, midazolam 2.0 ㎎ and rocuromum 50 ㎎. It was noted that ventilation of the lungs via mask was difficult. Despite insertion of an oropharyngeal airway, ventilation proved to be more difficult. Intubation was attempted. Direct laryngoscopy (Macintosh 3 blade) revealed a 3-4 ㎝ tranlucent cyst arising from the left vallecula. The cyst completely obscured the view of epiglottis and vocal cords, preventing intubation despite multiple attempts by three anesthesiologists. StafF anesthesiologist was aspirated cyst using a 16-guage needle, syringe and 20 ㎖ of serous fluid were aspirated from cyst. The epiglottis and vocal cord were then exposed and tracheal intubation was performed easily with a size 7.0 cuffed oral tracheal tube. Anesthesia and the operation then proceeded uneventfully, following laparoscopic colecystectomy, an ENT surgeon removed the cyst.
