We should treat carefully the one related to human rights among a large number of decision-making in our daily lives. As it is necessary to obtain physical evidences in the process of criminal investigation for solving a certain crime based on the principle of evidence, it leads to an increase in demand for forensic science and forensic geology. Forensic geology could be regarded as a fusion discipline of geology and forensic investigation and it is principally concerned to the study on the connection of a suspect and a crime scene with soil evidence which could be experimented using geological data and methods. So these results could be used as valuable information in a court. After its academic foundation has been builded since the last 1970s, its research objects have been expanded from soil evidence like rocks, minerals, soils, sediments to sociocultural, political, military and medical objects like ancient relics, mines, corpses. Its role is expanded from the simple finding of a particular location to the examination of archaeological theories and historical facts, the testimony of the cause of environmental pollution and the chronic demonstration of geological distribution of plants and anthropological origination. And these bring this discipline promptly to accept developed geological methodologies and to satisfy various forensic geological needs. Specialized forensic investigation institutes work actively for the R&D activities of forensic geology. In Korea, national institute of scientific investigation works a small part of forensic geological activities in total activities of forensic investigation. In conclusion, we concern to the importance of systematic discussion of building in proper position of forensic geology through its R&D methods, application cases of its performance and etc. based on geological characteristics in our country by a specialized geoscience institute.

The curtain-wall work has been more frequently applied in the construction industry since demand of high-rise buildings has been increased. The curtain-wall work is usually performed with the frame work simultaneously for reducing construction period, but it might be delayed because of several problems caused by interference of process. However, there is not an appropriate tool which can be used by a work manager for adjusting quantity of the construction equipments or the workers when the curtain-wall work was delayed. To resolve this problem a construction simulation anticipating and analyzing potential problems before starting the work can be applied in the curtain wall work. This research suggests a general model for the curtain-wall work by using construction simulation and produces a combination of construction equipments and workers which can estimate optimum work productivity.

Purpose : The study aimed to evaluate the efficacy of auditory brainstem response(ABR) as a screening tool in children with speech and language disorders. Methods : Between January 1, 1999 and December 31, 2001, 139 patients with chief complaints of speech and language delay were recruited from the pediatric neurology clinic, Kyungpook National University Hospital, Daegu, Korea. They had ABR on entry and the clinical data were then analyzed. Results : Fifteen out of 139 cases(10.8%) showed abnormal findings; seven had pervasive developmental disorders, four had developmental language disorders, and four were noted to have other conditions. Among them, seven cases were noted to have conductive hearing loss and eight had sensoryneuronal hearing loss. We also evaluated the normal values in children at the ages of 18 months to seven years. The mean latency of wave I and V were $1.40{\pm}0.13$ and $5.57{\pm}0.26$ respectively. Interpeak latency of I-V was $4.18{\pm}0.24$. Conclusion : Based on these findings, ABR has proved to be a highly sensitive and specific index of hearing impairment. It should be used as a screening tool in children with speech and language disorders.

홍수위험도 추정에 있어서 불확실성은 수리, 수문, 구조, 환경 및 사회경제적인 불확실성과 관련 있으며, 수리 수문학적 불확실성은 주로 수리 수문학적 현상과 그 과정에 대한 불완전한 지식, 그리고 그 과정에 포함된 매개변수들에 대한 불완전한 지식과 관련이 있다. 이러한 여러 가지 불확실성은 홍수위험도 추정에 있어서의 불확실성에 중요한 요인으로 작용하므로 불확실성을 설명하기 위한 통계적 정보는 신뢰성 있는 홍수위험도 추정에 있어서 선행조건이라 할 수 있다. 이러한 불확실성 요인중 강우의 공간분포에 대한 신뢰성 있는 추정은 수자원 해석 및 설계에 있어서 필수적인 요소이다. 강우장의 공간변동성에 대한 고해상도 추정은 홍수, 특히 돌발홍수의 원인이 되는 국지성 호우의 확인 및 분석에 있어서 중요하다. 또한 강우의 공간 변동성에 대한 고려는 면적평균강우량 추정의 정확도를 향상시키는데 있어서 중요하며, 강우-유출모델의 모의결과에 대한 신뢰도를 향상시키는데 큰 영향을 미친다. 최근 공간자료에 대한 공간분포예측에 있어서 공간상관성을 고려할 수 있는 공간통계학적 기법의 적용이 증가하고 있으며, 이러한 공간통계학적 기법의 적용에 있어서 신뢰성 있는 모델 매개변수의 추정 및 불확실성 평가는 공간분포 예측결과에 대한 신뢰성을 향상시키는데 중요한 역할을 한다. 외국의 경우 공간분포예측 및 모의, 매개변수의 불확실성 평가 등과 관련하여 활발한 연구가 이루어지고 있는 반면 국내 수자원 분야에서는 아직까지 활발한 연구가 이루어지고 있지 않은 실정이다. 국내의 수문설계실무에서와 같이 확률홍수량을 강우빈도분석과 강우-유출모델을 이용하여 추정할 경우 확률홍수량 추정에 있어서 확률강우량 및 공간분포에 대한 불확실성과 강우-유출모델에서의 불확실성이 확률홍수량 추정에서의 불확실성에 영향을 미치며, 이후 연피해기대치 추정과 같은 홍수위험도 추정의 불확실성에도 영향을 미치게 된다. 따라서 본 연구에서는 강우공간분포의 불확실성을 고려한 홍수량 추정을 위하여 공간추계모의 기법인 CEM을 적용하여 강우공간분포의 불확실성을 정량화하고 강우-유출모델의 입력 강우량에 대한 확률분포를 추정하였다. 강우-유출해석의 경우 유효우량 및 홍수수문곡선 산정을 위하여 국내 수자원 실무에서 가장 많이 적용되고 있는 NRCS CN 기법, Clark 및 Muskingum 모델을 적용하였다. 이로부터 강우공간분포의 불확실성 추정, 소유역별 입력 강우량에 대한 확률분포의 추정 및 재현기간별 확률홍수량의 불확실성 정량화 방안을 제시하였다. 이러한 결과들은 풍수해저감대책, 유역종합치수대책 등 각종 수자원 계획 및 설계실무에서 확률홍수량 및 홍수 또는 재해위험도 추정의 신뢰성을 향상시킬 수 있는 방법론적 대안으로 활용될 수 있을 것으로 판단된다.

Purpose: Recurrent abdominal pain (RAP) is common, affecting between 7% and 25% of school-aged children and young adult. This study was designed to assess the relationship between RAP and depressive trends in school-aged children. Methods: In 1999, We surveyed 1,181 elementary school children (566 boys and 615 girls) whose ages ranged from 9 to 12 years. The degree of depression was compared between the group with RAP and normal control group without RAP according to Korean Children's Depression Inventory (CDI) of Kovacs and Beck. Results: The number of the group with RAP was significantly higher in female (25.7%) than in male (18.9%). The most common site of abdominal pain was periumbilical. The mean depression score in the group with RAP was higher than that of the control group. The depression score was significantly higher in the group with RAP who has frequently pain and additional symptoms. The depression score was significantly higher in the group with RAP who prefered to play alone, did not enjoy going to school and had few friends than in the group with RAP who had a lot of friends, had active and meticulous characters. The depression scores were not significantly different according to the duration of abdominal pain, the onset time of pain, and the day of pain in the group with RAP. Conclusion: The depression score of the group with RAP was higher than that of normal group. So, there is relatively a specific association between childhood RAP and depression in school aged children. It is good for physicians to consider psychological support in the treatment of childhood RAP.

In recent years, there are some confusions related to the definition and existence of mountain ranges, which have been described in current geography text books. We contend that these confusions came from the lack of understanding on the geomorphological processes that form the mountain system in Korea. This research attempts to clarify the definition of mountain ranges and offer geological and geomorphological explanations about the formation of them. Based on the analyses of the social and cultural causes underlying the recent debates on the existence of mountain ranges, we tried to identify the relationships among the definition of mountain ranges, geological structure of Korea, and the forming processes of mountain ranges. The current and past mountain range maps were compared with geological structures, geological maps, surface curvature, and hill shade maps. The latter two maps were derived from a Digital Elevation Model of the Korean Peninsular. The results show that we are able to prove the existence of most mountain ranges, which provides a useful framework to understand the geological evolution of Korean peninsular and formation of mountainous landscape of Korea. In terms of their morphological continuity and genesis, however, we identified five different categories of mountain ranges: 1) Uplift mountain ranges(Hamkyeong Sanmaek, Nangrim Sanmaek, Taebaek Sanmaek), which were formed by the uplift processes of the Korean Peninsular during the Tertiary; 2) Falut mountain ranges(Macheonryeong Sanmaek, Sobaek Sanmaek, Buksubaek Sanmaek), whirh were directly related to the uplift processes of the Korean Peninsular during the Tertiary; 3) Trust mountain ranges(Jekyouryeong Sanmaek, Kwangju Sanmaek, Charyeong Sanmaek, Noryeong Sanmaek), which were formed by the intrusion of granite and consequent orogenic processes during the Mesozoic era; 4) Drainage divide type mountain ranges, which were formed by the erosion processes after the uplift of Korean Peninsular; 5) Cross-drainage basin type mountain ranges (Kangnam Sanmaek, Eunjin Sanmaek, Myelak sanmaek), which were also formed by the erosion processes, but the mountain ranges cross several drainage basins as connecting mountains laterally We believe that the current social confusions related to the existence of mountain ranges has partly been caused by the vague definition of mountain ranges and the diversity of the forming processes. In order to overcome theses confusions, it is necessary to characterize the types of them according the genesis, the purpose of usages and also the scale of maps which will explains the mountain systems. It is also necessary to provide appropriate educational materials to increase the general public's awareness and understanding of geomorphological processes.

The purpose of this paper is to explain MacIntyre's critique of moral pluralism of modern society and reveal the limits of his critique of liberalism. It is a distinctive feature of the social and cultural order that we inhabit that disagreements over central moral issues are peculiarly unsettleable. Debates concerned with the value of human life such as those over abortion and euthanasia, or about distributive justice and property rights, or about war and peace degenerate into confrontations of assertion and counter-assertion because the protagonists of rival positions invoke incommensurable forms of moral assertion against each other. We usually call this situation 'modern moral pluralism' and concede as the natural outcome of the activities of human reason under free institution. But in After Virtue, MacIntyre vigorously criticizes modern moral pluralism. The main cause he took which brought about this state of affairs was the failure of 'the Enlightenment project'. According to MacIntyre, the Enlightenment project which has dominated philosophy for the past three hundred years promised a conception of rationality independent of historical and social context, and independent of any specific understanding of man's nature or purpose. But not only has that promise in fact been unfulfilled, the project is itself fundamentally flawed and the promise could never be fulfilled. In consequence, modern moral and political thought are in a state of disarray from which they can be rescued only if we revert to an Aristotelian paradigm, with its essential commitment, and construct an account of practical reason premised on that commitment. But one of the deepest difficulties with the argument of After Virtue is that the very extent of its critique of the modern world seems to cast doubt on the possibility of any realistic revival under the conditions of modernity of the Aristotelianism which MacIntyre advocates. Especially when we consider we are not only the characters found in our narratives but also we ourselves are the author of our own narratives. Moral pluralism is not seen as disaster but rather as the natural outcome of the activities of human reason under enduring free institutions.

The Reform Movement(戊戌變法) of 1898 was a boundary tablet of modern history of science and technology which inherited the past and ushered in the future. Kang Youwei(康有爲), as a leader, his scientific thoughts opened up the way of Chinese enlightenity campaign and pushed the development of Chinese modem science and had an important position in modem history of scientific thoughts. The dissertation analyses the source, establishment and content of Kang Youwei. Kang Youwei developed the useful and discarded the useless of the view of implement science held by the Westernized Party, undertook a deep and throughout thinking on the nature of science, had cognition of scientific methods and spirit, by which he criticized negative proneness of ancient Chinese views of science. He put forwards a series of practical suggestions on political reform that provided a solid guarantee and support in system for scientific development. Kang Youwei rooted in the soil of Chinese traditional academic culture, but also western learning in modern western civilization. Kang go through Westernization Movement since the in-depth study of Western natural and inevitable outcome of the social sciences, are giving to science and technology. Although he was originally of Western "science" has a lot of misunderstandings and prejudices, but these shallow hazy perceptual knowledge, his view of science which constitutes the basis of the formation. In the course of scientific inquiry, Kang has begun to explore the essence of scientific development. He has a gut feeling that behind the scientific discovery of the existence of a force, which is the scientific truth and is used to grasp the scientific method. After contact with the Western world, with the traditional "Heaven(天)", and modern Chinese intellectuals began to "axiom(公理)" to recover his traditional "Heaven" of the new understanding is reflected mainly in "Zhutianjiang(諸天講)". "Zhutianjiang" is the Kang Yuwei in the absorption of traditional astronomy knowledge base, will the traditional arithmetic, as well as Buddhism and the West since the twentieth century, new knowledge of astronomy combines written. Kang while recognizing that scientific instruments, is nothing more than an extension of the role of the human senses and make the "Dao(道)" is more clear, but the "artifacts(器物)" caused by the inherent limitations of the limited nature of human knowledge, which is "Heaven" boundless nature of the broad terms, refused to concede defeat to. In reality, the activities of political reform, he gradually recognize this real-world helpless, and he recognized that the real world to achieve common ground of social ideal is impossible, so he chose comfort in life that people really get a stage of "Tianyou(天遊)". This is the cause that his writing "Datongshu(大同書)", at the same time, followed by writing "Zhutianjiang" talk "Tianyou".

Purpose : We performed a study of clinical findings of Mycoplasma Pneumonia in children, to know differences between recent clinical manifestations of Mycoplasma pneumonia and previous studies. Methods : The subjects of this study were 393 children who were diagnosed as Mycoplasma pneumonia with high titers of Mycoplasma antibody(${\geq}1$ : 160) or fourfold rises of Mycoplasma antibody at Chung Ang University Hospital from January 1998 to December 2003. We practiced a retrospective study on the clinical manifestations of Mycoplasma pneumonia based on their medical records. Results : Male to female ratio was 1.06 to 1 and mean age was $4.32{\pm}2.94years$. The highest incidence was in the age of 2 to 3 years(18.6 percent). Most frequent months were October, and November in 2000, April in 2002, and October and, December in 2003. Twenty six point seven percent showed allergic diseases. Second degree relatives of 10.7 percent patients had allergic diseases. Forty three point three percent were admitted before this admission for pneumonia. Allergic tests were positive in 65.7 percent. Cough, and sputum were the most common symptoms and abdominal pain, and vomiting were the most frequent extrapulmonary symptoms. Atelectasis and pleural effusion were seen in 2.5 percent and 1.8 percent. Infiltrations were more common on the right side. Titers of each simultaneous test for cold agglutinin and mycoplasma antibody were not in proportion to each other (P=0.163). Conclusion : The onset age of mycoplasma pneumonia was found to be lower than it used to be. More patients had a past medical history or a family history of allergic disease, and more wheezing was heard and associated with recurrent pneumonia.

Purpose : It has been previously reported that for patients with Mycoplasma pneumoniae pneumonia was previously recognized that overt illness is unusual under the age of three and the peak incidence of illness occurs in school-aged children. However, a higher incidence of this illness in younger children has been recently noted. Thus we investigated the incidence of M. pneumoniae pneumonia. Methods : The study subjects were 414 children who were diagnosed with M. pneumoniae pneumonia from January 2004 to December 2006 at Myong Ji Hospital were enrolled. The diagnostic criteria consisted of an anti-mycoplasma antibody (AMA) titer greater than 1: 320 or a four-fold rise in the titer at follow up. Results : The age distribution was as follows: before 2 years of age: 58 patients (14%), 2-4 years of age 157 patients (37.9%) and 5-15 years of age 199 patients (48.1%). The yearly incidence for the children before 5 years of age was 52 (44%), 49 (44.6%) and 114 (61.3%), respectively. The distribution according to the antibody titer was as follows; 1: 320 in 130 patients, 1:640 in 63 patients and greater than 1:1,280 in 221 patients. The hospital stay according to the antibody titer was not significant according to either age or the AMA titers. Conclusion : M. pneumoniae pneumonia showed a peak incidence in preschool children with a higher prevalence in children under the age of three than was previously recognized. The emergence of M. pneumoniae pneumonia as a cause of community acquired pneumonia in younger children calls for an epidemiologic study to investigate the changes of the pathogens in this age group and to recommend the proper treatment.
