The problem of space debris has been dealt with at the STSC of the COPUOS. The technical discussion at the said Committee was finished by adopting the Technical Report in 1999. Its legal discussion will be followed very soon at the LSC of the COPUOS. In this paper, I try to outline certain legal points concerning the space debris.

In this paper, we propose an approach which contains with constructing a bibliography information database, extracting the fields of research, and researching trend of them, using data mining. To apply our approach to IEICE Technical Report (nonlinear problem society), the database was constructed based on its report, keywords were analyzed using the frequency analysis and the association analysis, and we discussed about the result. We could extract some field of research from the result.

The development of environment-friendly Energy Resources (New Renewable Energy Resources) is one of the global topics these days, considering CO2 Reduction Agreement by Kyoto Protect and the limit of Conventional Energy Resources in near future. Among the New Renewable Energy, Wind Energy is the most feasible Renewable Energy in view of economical and technical aspect at this moment. Last 10 years the Wind Energy Development was really dramatical in Europe. especially in Germany, Denmark and Spain. In this circumstance World Wind Energy Conference was held in Berlin Germany, in order to review the present status and future development of the Wind Energy. This report is a brief report of the Conference .

Various anesthetic techniques have been utilized for maxillo-mandibular fixation. We report the case of a patient with bilateral condylar and zygomatic arch fractures who had severe pulmonary dysfunction. The patient was administered bilateral image-guided Gasserian ganglion block through the foramen ovale to achieve surgical anesthesia. The technical details, advantages, and disadvantages of this rather unusual technique are discussed. The procedure could be a feasible technique when performed meticulously in cases where other approaches are deemed difficult.

The present review report introduces the existing analysis codes and physical modeling of two-phase flow associated with initiating event of HCDA in Liquid Metal Reactors for the effective study in the future, because the related research has not been systematically carried out in Korea compared with other areas. The description in this report is specifically addressed to the results yielded from careful review of the technical concepts on the two-phase flow modeling in the SAS2A code which was developed in ANL. The report is prepared in 2 parts based on the definite physical phenomena. The liquid slug and gas behavior models are main representations in the part (I) and (II), respectively. In this regard, it is expected that this report provide a fundamental knowledge on the two-phase flow model in LMR and, thus, contribute to establishment of the necessary HCDA analysis technology concerned with the LMR development in Korea.

Ferro-cement is a composite material made of portland cement mortar and wire(or chicken wire) reinforcement. In most cases, as a shipbuilding material, reinforcing steel rods and steel pipes are also used. This report will review the technique of ferro-cement boat building and will guide the working details. Beyond these, this report will present some test results of the ferro-cement test pannels and will compare those with the other well known shipbuilding material. As a matter of fact ferro-cement application to the shipbuilding material is quite not a new theory. There were already lots of case studies and actual ship building applications. But the technique to do this is not easily available to the interested persons and amateur shipbuilders. Therefore this report will stress most its "state-of-the-art review" and give kind guidance in using ferro-cement as a shipbuilding material. For the more interested research worker, technical references as much as listable are printed in the bibliography section on this report.

This paper is to review the conclusions of the Athens conference that has so far contributed to the conservation world. It is normally called the conclusions of the Athens conference as the Athens charter. But the conclusions of the Athens are not as same as the Athens Charter regarding the contents. The former had more valuable contents than the latter regarding historic monuments. And the report of the Athens conference including 56 articles and 500 pages with 55 photos was published in 1933 by the International Museums Office. But little attention has been given to the report of the Athens conference. Therefore the point I want to make is to review to the report in order to understand the agenda of the conference and to examine the Anastylosis in Acropolis. In conclusion, these agendas and the articles in the report show us that the conference was sort of milestone with some advanced modern philosophical and technical concepts about conservation and restoration of historic monuments. Also when the term of anastylosis turns to reconstruction in archaeological sites, we are going to face with the problems of authenticity.

최근 들어 컴퓨터의 보급과 인터넷 기술의 발전으로 건설사업을 수행하면서 발생하는 서식문서, 보고서, 계산서, 시방서 등 각종 문서를 컴퓨터를 사용하여 작성하고 작성된 전자문서는 인터넷을 통해 활발히 유통하고 있는 실정이다. 기존 전자문서는 다양한 포맷으로 작성되어 포맷간의 호환성의 문제 결여와 문서 내용이 의미하는 것을 사람과 컴퓨터가 함께 인식할 수 있는 건설관련 기술문서를 단순하게 전자적인 형태로 작성하기 않고 특정 하드웨어나 소프트웨어에서 구애를 받지 않으면서 표준화된 정보체계에 따라 전자문서화하고 기술문서의 활용성 제고를 위한 요구가 점차 강조되고 있다. 본 연구는 이러한 요구를 충족시키기 위해 건설CALS/EC의 구조적 언어인 XML 기술을 사용하여 기술문서를 전자문서화하기 위한 개발 절차와 방법을 마련하였다.

Recurrent acute pancreatic attacks is a rare clinical condition (2-5% of all acute pancreatis) in children and is mainly idiopathic in most cases. Sometimes it may be associated with congenital anomalies, metabolic diseases or hereditary conditions. Isovaleric acidemia (IVA) is a rare autosomal recessive amino acid metabolism disorder associated with isovaleryl coenzyme A dehydrogenase deficiency presenting the clinical findings such metabolic acidosis with increased anion gap, hyperammonemia, ketonemia, hypoglycemia, "the odor of sweaty feet," abdominal pain, vomiting, feeding intolerance, shock and coma. Recurrent acute pancreatitis associated with IVA have been rarely reported. Herein; we report a child who admitted with recurrent acute pancreatic attacks and had the final diagnosis of IVA. Mutation analysis revealed a novel homozygous mutation of (p.E117K [c.349G>A]) in the IVA gene. Organic acidemias must kept in mind in the differential diagnosis of recurrent acute pancreatic attacks in children.

While human error has been one of the main technical issues from the early era of human factors engineering, it still remains hot and somewhat vague due to the various types of the concepts and words on human errors in practice. There may be some technical limitations hindering human error prevention activities. This paper introduces the human error activities described in the papers if this issue of ESK Journal according to a few criteria proposed for more effective technical review. And two basic technical issues are discussed on the concepts, perspectives, and classifications about human errors. Each activity shows its own artifacts associated with the safety purpose and the nature of the industry. This paper also provides a set of new technical bases proposed for a more effective management of human errors by considering the dependability, representativeness, and structuredness of human errors. Additionally, this paper includes some new challenges over the current prevention-oriented activities; positive utilizations of human errors to training/education, advertisements, fun and entertainments, and nudges.
