This study is a statistical analysis for properties of bed elevation with distance along the open channel by stochastic models and spectral model. In this study, AR(2) model more adequate than ARMA(1,1) model in the equilibrium bed elevation of open channel. In the case of dunes, the spectrum is proportional to the wave number to the power-3 but in the case of ripples, this is not confirmed. Spectral model is more dependent on Re than Fr in the experimental data of shallow open channel.

본 연구의 목적은 컴퓨터 게임에 대한 청소년과 그들의 교사, 학부모의 인식을 조사하여 각 집단별 인식 간에 차이가 있는지, 있다면 어떤 영역에서 가장 큰 차이를 보이는 지를 알아보는 것이다. 이를 위해 남자 중학생 297명, 이들의 교사 124명, 학부모 278명을 표집하여 컴퓨터 게임시의 자기 통제력에 대한 인식, 컴퓨터 게임이 학습활동, 교우관계, 부모님과의 관계, 자아존중감, 건강에 미치는 영향에 대한 각 집단별 인식의 차이를 분석하였다. 연구결과를 보면, 중학생들은 대체적으로 컴퓨터게임에 대해 긍정적으로 인식하고 있었다. 컴퓨터 게임은 스트레스 해소를 위해 가장 필요하고, 성적에는 별로 영향을 주지 않는 것으로 인식하고 있었지만 교우관계에는 부정적 영향을 주는 것으로 보고 있었다. 교사들은 대체적으로 컴퓨터 게임이 중학생들에게 부정적으로 작용한다고 보고 있었다. 특히 게임에 대한 자제력 부족으로 성적에 부정적인 영향을 줄 것이고 이로 인해 학부모들과 갈등이 초래될 것으로 인식하고 있었다. 부모들은 대체적으로 교사보다는 긍정적으로, 그러나 학생보다는 다소 부정적으로 컴퓨터게임에 대해 인식하고 있었다. 교사들은 컴퓨터게임이 학생과 학부모의 관계형성에 부정적일 것으로 보고 있었으나 실제 학생과 학부모들은 그렇지 않은 것으로 나타났다 Generally, the middle school students play the computer games in their spare times or for pleasure. But, their parents and teachers emphasize on the negative effect of the computer games and restrict the students to play the games. This difference comes from different standpoints on the computer games among parents, teachers, and students. In this context, this study aims at investigating the different views of the computer games among parents, teachers, and students. Regarding a view of the computer games, this thesis puts it as being influenced by the conditions of the self-control on playing the computer games, the students' associates, the relations between the students and their parents, the self-respect, and the health. According to the results, the middle school students play the computer games in forty three percent of their leisure times for pleasure and getting rid of stress. In addition, they can not find an alternative but the computer games in their spare times. As to the difference of the views on the computer games, the middle school students and the parents are positive but the teachers are not. The students are the most positive of the computer games. In particular, they take the affirmative to the self-control on playing the computer games and the effect on their health, but regard the computer games as keeping bad company. The teachers have the most negative assertion toward the computer games. Mostly, except the students' associates and self-respect, the teachers do not agree to the computer games to bring positive effect on the students. Comparatively, the parents are positive of the computer games but less than the students are. They believe that the computer games have the positive effect on the self-control on playing the computer games and the students' health. Nevertheless, they make an negative assertion in relations to the learning and the students' associates. Therefore, this study is able to form a conclusion that it might be needed for the parents and teachers who have the negative attitude toward the computer games to put themselves in the position of the students to find the positive effects of the computer games and suggest appropriate guidelines for the students as maximizing positive effects of the computer games.

We would like to compare the case of treatment using surgical operation with the case of treatment using conservative method to the patients who are diagnosed as cervical disc herniation. This study has been done with each 21 and 83 patients who were available for 1 year -100 patients who had cervical disc herniation were treated with surgical operation and 175 patients were treated with conservative treatment in Chungnam National University Hospital. Each of convalescence were compared to odom's criteria along with the age of outbreak of illness, numbers of diseased segments, which is calculated by loss of radiating pain, subjective satisfaction, and return to their job. The group who are over 60 years old, surgical treatment had positive result. Also the group who are under 60 years old, conservative treatment had positive result. Radiculopathy due to cervical disc herniation had good result by surgical treatment when the patient is over 60 years old and has a few diseased segments. Therefore, it is considered that we should take a cautious attitude in choice of treatment.

EMTP MODELS를 이용한 2차 아크 모델링 기법에 관한 연구

안상필,김병천,김철환 成均館大學校 科學技術硏究所 1998 論文集 Vol.49 No.2

The most frequent faults on overhead transmission lines are single-phase to ground arc faults in air. On HV/EHV lines, the single-phase autoreclosure is an effective means to clear the fault while retaining the system stability. For the improvement of an adaptive SPAR(Single-Phase Auto-Reclosure) and novel protection schemes, it is important to simulate arc faults. But, it is difficult to reproduce the real arc behaviour, i.e. the extinction phenomenon exactly by computer simulations due to extremely random behavior of secondary arc. For simplicity of simulation processing, a simulation language, called MODELS, is used. It has been added to the EMTP, which permits to interface control system with power system. This paper proposes a new computer modeling techniques for the primary and the secondary arc separately, which can be implemented with EMTP MODELS routine, and the the performance of the proposed model is simulated on a typical 154 [kV] korean transmission line system.

안덕선,한승규,구상환,한재식 大韓成形外科學會 1995 Archives of Plastic Surgery Vol.22 No.5

This retrospective study includes consecutive 54 Blow-out fractures patients to whom underwent surgical correction (June 1988-Feb 1994) and 25 patients have been followed up for more than 1 year. The diagnoses of blow out fracture was made through a physical examination, X-ray, and CT and It is confirmed at the time of surgery. Initial physical examination revealed limitation of ocular motion and diplopia in all 25 patients, and infraorbial nerve hypoestesia in 18 patients, and enophthalmos in 1 patient. There were 27 patients who had associated ocular injury including subconjunctival hemorrhage, angle recession and iris sphincter damage. and the three most common causes of blow-out fractures were traffic accident, fist blow and fall down. The latent period between injury and surgical intervention was average of 8 days and the longest time was 12 days. Surgical approach was done by subciliary incision and autogenous (10 cases) or synthetic (37 cases) implant was inserted over the fracture site in 47 patients. The floor and medial wall of orbit were the frequent site of blow-out fracture in this retrospective study. Among 28 patients who have been followed up for more than 1 year, 3 patients had diplopia persistently which developed only when the patient was tired, and 5 patients had late developed enophthalmos. We found that early surgical reduction of blow-out fracture with implant gave a favorable results without any significant complications.
