The rates of photodegradation, reactivities, and mechanisms of photooxidation for the aqueous solution containing with halogen derivatives of aliphatic hydrocarbons have been discussed with respect to the kinds of photocatalysts, concentration of photocatalytic suspensions, strength of radiant power , time of illumination, changes of pH of substrate solution, wavelength of radiation, and pressure of oxygen gas saturated in the solution. These aqueous solutions suspended with 0.5 gL^-1 TiO_2 powder have been photodecomposed in the range of 100 and 93.8% per 1 hour if it is illuminated with wavelength (λ≥ 300nm) produced from Xe-lamp(450W). The photocatalytic abilities have been increased in the order of Fe_2O_3 < CdS < CeO_2 < Y_O2_3 < TiO_2, and rates of photodegradation for the solution have maximum values in the condition of pH 6∼8 and 3 psi-O_2 gL^-1. These rates for the photooxidation per 1 hour were dependent on the size of molecular weight and chemical bonding for organic halogen compounds and the rates of photodegradation were increased in the order of C_2H_5Br < CH_2Br_2 < C_5H_11Cl C_2H_4Cl_2 < trans-C_2H_2Cl_2 < cis-C_2H_2Cl_2 The t_1/2 and t_99% for these solutions were 5∼21 and 40∼90 minutes, respectively, and these values were coincided with initial reaction kinetics(r_0). It was found that reaction of photodegradation has the pseudo first-order kinetics controlled by the amount of h^+_VB diffused from a surface of photocatalysts.

김원일은 우리시대 대표적인 분단문학 작가이다. 1966년 대구매일신보에 「1961. 알제리아」가 당선된 이래 여러 편의 중, 단편 소설을 발표했다. 그러던 중 1973년 「어둠의 혼」이 당선된 것을 기점으로 『노을』(1978), 『겨울골짜기 상, 하』(1987), 『마당 깊은 집』(1988), 『불의 제전1-7권』(1983-1997), 등 탁월한 분단문학을 집필했고 이 시대 대표적인 분단문학 작가라는 평가를 받고 있다. 그러나 1990년 이후 즉, 범박하게 말하자면 시기적으로 그의 후기소설이라고 할 수 있는 작품들은 분단문학의 범주에 들기 어려운 것들이다. 그의 후기 작품 세계는 신의 초월성과 내재성 뿐만 아니라 인간 내면 깊숙이에 잠재된 원형성과 실향성 등 인간의 내면적이고 근원적인 문제에 관심이 집중되어 있다. 그러므로 그를 단순히 ‘분단문학 작가’라는 카테고리 속에만 묶어두어서는 안 될 것이다. 따라서 본 연구자는 그가 깊이 관심했던 중요한 모티브의 하나인 ‘실향성’과 ‘종교’ 그중에서도 특히 ‘기독교’에 천착한 주제를 가지고 씨름해 온 작품 중에서 『가족1,2』를 텍스트로 삼았다. 이 작품은 정치(精緻)하게 읽어갈수록 두 개의 큰 기둥이 보인다. 김치효를 중심으로 위로는, 북에서 피난 온 아버지 김석현 옹과, 아래로 3명의 아들들로 대변되는 ‘실향성(失鄕性)’의 모티브를 읽어낼 수 있다. 또한 김치효의 아내인 장경순와 딸인 김선결, 그리고 그의 애인인 민한세 전도사로 상징되는 두 개의 기독교가 선명하게 존재한다. 공교롭게도 남성들은 ‘실향성’에, 그리고 소설 중에서 여성들은 ‘종교성’에 깊이 관계되어 있다. 실향민 모티브에는 공간적 고향을 잃은 김석현 옹(공간적 실향민)과 그에 대비되는 무의미성(무목적성)으로 궁극적인 고향을 상실한 3명의 아들들이 이항대립적인 위치를 점하고 있다. 반면에 소설 후반부로 갈수록 내세적이고 시한부 종말론을 주장하며 사이비로 빠져드는 장경순 여사와 무신론적 실존주의자로 살다가 여러 사건을 통해 기독교로 귀의하는 둘째 딸, 김선결이 대표하는 사회참여적 기독교, 혹은 사회변혁적인 기독교가 등장한다. 본 연구는 이 두 개의 서로 다른 정점에 있는 주제에 대해 연구하고, 이 둘이 하나로 이어질 수 있는 가능성에 대해 모색해 보았다. This paper is concerned about investigating the christian thought in Kim won il’s late literature. He is very significant polarized literature author. He has been said that he was the most specific novelist in our period. There is few to deny this fact. However, I don’t think so. Even though we recognize that he wrote many excellent polarized works, is it possible for us to limit his late works as polarized literature? I divide his works as 3periods. The first literature works was written under the effect of existentialism from 1966 to 『sunset』(1978) The second literature are called as the polarized literature period including 『sunset』(1978) 『The fire carnival』(1982-1997) 『The wind and The river』(1985) 『The winter valley』(1987) 『A house which have a large yard』(1988). The third period literature has been written about the theme like disabled person, religion, social equality and utopia, The displaced person, family, and faith. Above all, I realize that he takes many concern about religious reality. There are especially many instance in his late novel 『The family』(2000) Therefore, I want to recognize his late works as religious literature.
저작근 골막하 박리를 이용한 만성 재발성 탈구의 치험례

Chronic recurrent dislocation(CRD) of the jaw has various etilogical causes, including trauma, congenital or acquired neurological illness, ingestion of certain medicines, incorrdination of the neuromuscular astivity of the chewing muscles, articular anatomical alteration, etc. Various surgical methods have been advocated for the treatment of the CRD. They may be divided into two groups: procedures designed to limit translation of the condyle and procedures eliminating obstacles in the condylar path. Hypomobility of mandible can be developed after BSSRO and it is probably caused by scar contracture, atrophy, and myofibrosis. Many authors, therefore, emphasized the importance of physical therapy especially after BSSRO to prevent the complication. Based on that idea, we designed more conservative surgical method to limit mandibular openning compared the methods that previously introduced and tried to treat the CRD. This new method consists of extensive subperiosteal dissection of masseter and the temporalis muscle under local anesthesia and use of intermaxillary elastics for some periods.

The purpose of this study is on examining closely and precisely the correlations between the realities with using sporting centers and satisfaction of people using them. Firstly, in order to achieve that purpose, I have analyzed the differences in people's satisfaction that are caused by characteristics of the Population Statistics. Then I have studied about effects of realities on people using the sporting centers to the satisfaction. In this research, some health clubs in Teagu have been focused on the frame to be required. I picked 250 people randomly first but excluded 67 people who have been considered as being answered with insincerity or have been omitted due to insufficiency on the final questionnaire, which means finally 193 people were completely answered. This study includes totally 42 questions that are made up of 4 Population statistical questions about tools used as assessments, 3 questions about causes of the realities of sporting activities, and 35 questions about causes of the satisfaction rate by using some analyzing methodologies that are used, such as the frequency analytics, t-test, One way anova, scheffe's post-inspection, interrelationship analytics, regression analytics, and so on. Could get some meaningful results like following with using those methodologies mentioned before. Firstly, I could find out meaningful differences between different categories, amongst the Population Statistics characteristics in people using the sport centers, that were leader's ages, equipment satisfaction differentiated by the standards of education in the sporting programs, equipment satisfaction in the leader's different wages, and so on. Secondly, in the lower leveled realities causes, the equipment satisfaction has been revealed statistically around 5%(actually 8.1%) in frequency of participation whereas the programs have been indicated approximately 5%(actually 7.0%) in the term of participation.

The purpose of this study is to analyse the work and the leisure attitude based on the income. The subjects participated in the study were 594 as a adult : 302 male, 292 female. On the basis of positivistic are sociological analysis, the conclusions are as follow. First, as the leisure attitude based on the income, the group of low income estimated the leisure attityde the most positively, in the next place, the group of middle, high in order, but there was statistically no significant differened. Thus, The leisure attitude of the korean people was not different from group in terms of the income relation. Second, as the Work attitude based on the income, the group of low income estimated the work attitude the most positively, in the next place, the group of high, middlem in order. There was statistically significant difference in the P,.05 level. Thus, the work attitude of the korean people was different from group in terms of the income relation. Third, all the three groups estimated leisure more positive than work. The leisure view of the korean people was gradually changing in the comparing with the last times. Thus, we must practise the leisure education on the purpose of the effective use of leisure time and build up of sound leisur culture.

In order to investigate the possibility as a dyestuff, the spectra of imidazole azo derivatives were studied in comparison with phenyl azo ones. The λmax of imidazole azo derivatives was 17-23 nm longer wave region than that of phenyl derivatives and it means that imidazole azo dyes have more bathochromic effect than phenly azo dyes. The spectra of substituted 2'-oxyphenyl azo imidazole showed isosbestic points in accordance with the variation of pH range in the methanol-water solution. It will be due to the protonation and deprotonation of dyes in acid-alkali solution. The authors discussed these imidazole azo dervatives on the possibility as a disperse azo dye.

초음파 탐촉자로부터 방사된 음장을 모델링하는 것은 초음파 측정 모델을 구성하는 첫 번째 단계이며, 그 정확도를 결정짓는 핵심 요소이기 때문에 지금까지 다양한 연구가 진행되었다. 본 논문에서는 지금까지 제안된 다양한 기법 중에서 현재 널리 사용되고 있는 Rayleigh-Sommerfeld 적분 모델, 경계회절파모델(boundary diffraction wave model), 가장자리요소모델(edge element model)에 대해 간략하게 논의하고, 이 세가지 모델을 적용하여 평면 원형 및 사각형 초음파 탐촉자의 방사 음장을 계산하고, 각 기법의 정확성과 계산 효율을 비교하였다. Modeling of radiation beam from ultrasonic transducers has been investigated extensively, since it is one of the most important, fundamental issues that have great influence on the accuracy of an ultrasonic measurement model. Here, three popular radiation models, namely the Rayleigh-Sommerfeld integral model, the boundary diffraction wave model and the edge element model, are discussed briefly, and the radiation beam fields from ultrasonic transducers with planar, circular and rectangular cross-sections are calculated using these three models. Then, the accuracy and the time-efficiency of these methods are compared based on the calculation results.

Purpose : To review developmental salivary gland defect based on 12 reported cases and literature, and to guide radiographic diagnosis of this entity. Materials and Methods : The 12 cases of developmental salivary gland defect of Chosun University Dental Hospital in the last 4 years were analyzed and compared with previous reported cases. Result : 11 of the 12 cases were found in men, indicating a very strong male predilection. The peak age was in the 6th decade. These defects were situated just above or at the inferior border of mandible between the first molar and the mandibular angle, and always inferior to the mandibular canal. Only one case was superimposed with the mandibular canal, 6 cases were superimposed with the inferior border of the mandible. Conclusion : Characteristically, these defects had a special radiographic features such as ovoid shaped well-defined radiolucency located just above or at the inferior border of the mandible between the first molar and the mandibular angle, and always inferior to the mandibular canal. The recognition of these radiographic features were diagnostically valuable.
