Information structure can be conveyed by prosodic structure (Poser 1984 for Japanese; Inkelas and Leben 1990 for Hausa; Cho 1990 for Korean; Hayes and Lahiri 1991 for Bengali; Selkirk and Shen 1990 for Shanghai Chinese). Different subfields of linguistics and different theoretical perspectives suggest many distinct types of information structure: topic vs. comment, focus vs. background. old vs. new information, etc. The purpose of this paper is to investigate phonetic realizations of focus and topic among these information structures in Korean. For this purpose, we conduct a phonetic experiment where we examine duration, pitch and dephrasing in focus and topic structures. We make four findings through this study. First, duration of 'nun' varies depending on the information structure of the following constituent. Second, the degree of accentual phrase-initial rising is larger in contrastive topic and focused phrases than in neutral phrases. Third, a contrastive topic phrase always constitutes an Intonation Phrase on its own. Fourth, dephrasing occurs variously depending on gender and the number of the syllables within a phrase.

Ishizakiella supralittoralis (Schornikov, 1974) was collected from rock pools near Busan, South Korea, and is redescribed herein. It is the first record of this species from Korea, and also the first finding of a living population of Ishizakiella McKenzie & Sudijono, 1981 from the continental margins. Here we also comment on the diversity of Ishizakiella in Japan, possible existence of cryptic species, and provide a key to all six currently known species of this genus, including the two fossil ones.

An infection is less likely to elicit chronic inflammatory demyelinating polyneuropathy (CIDP) than Guillain-$Barr{\acute{e}}$ syndrome. We here report a case of acute-onset CIDP following hepatitis A virus infection and briefly comment on the potential mechanisms regarding the induction and chronicity of autoimmunity after a viral infection.

In this Paper we propose a navigation algorithm which can be used to estimate state vectors such as position and velocity for its motion control using multi-sensor output measurements. The output measurement we will use in estimating the state is a series of known multi-sensor asynchronous outputs with measurement noise. This paper investigates the Extended Kalman Filtering method to merge asynchronous heading, heading rate, velocity of DVL, and SSBL information to produce a single state vector. Different complexity of Kalman Filter, with biases and measurement noise, are investigated with theoretically data from KRISO's AUV. All levels of complexity of the Kalman Filters are shown to be much more close and smooth to real trajectories then the basic underwater acoustic navigation system comment)'used aboard underwater vehicle.

We derive the exact distribution of summation for random samples from uniform distribution and then compare the exact distribution with the approximated normal distribution obtained by the central limit theorem. To check the similarity between two distributions, we consider five existing normality tests based on the difference between the target normal distribution and empirical distribution: Anderson-Darling test, Kolmogorov-Smirnov test, Cramer-von Mises test, Shapiro-Wilk test and Shaprio-Francia test. For the purpose of comparison, those normality tests are applied to the simulated data. It can sometimes be difficult to derive an exact distribution. Thus, we try two different transformations to find out which transform is easier to get the exact distribution in terms of calculation complexity. We compare two transformations and comment on the advantages and disadvantages for each transformation.

Korean is well-known for its topic-prominent properties. In this paper, we look into several subtypes of topic constructions whose grammatical complexities have received much attention in generative grammar. From a semantic/pragmatic view, topics in Korean can be classified into three different types: aboutness, contrastive, and scene-setting. Meanwhile, syntax can classify topic constructions into two types, depending on whether or not the comment clause following topic has a syntactic gap linked to the topic. In this paper, we review some key properties of these topic constructions in Korean, and suggest that each type is licensed by tight interactions between syntactic and semantic constraints. In particular, the paper tries to offer a Construction Grammar analysis where each grammatical component is interacting in non-modular ways and in which the multiple inheritance network of constructions plays an important role in capturing cross-cutting generalizations of the topic constructions.

Polyvinylchloride(PVC) is variously used to produce food packaging, wrap film, sealing compound of drinking bottle cap. Safety of these PVC food package is controlled by Food Code, PVC regulation. This study was carried out researches on manufacture process, physical, chemical properties and monomer(CAS No., common name, molecular structure) of PVC to help the understanding of PVC material. Also, this study helps us the understanding of regulation through researches on the foundation of PVC regulation, the purpose of test and the comment of test method. It is considered that these informations of material properties and explanations of test method are very useful to PVC producers, users and analyzers of them.

Endoscopy has become a crucial diagnostic and therapeutic procedure in clinical areas. Over the past three years, we have developed a computerized system to record and store clinical data pertaining to endoscopic surgery of laparascopic cholecystectomy, pelviscopic endometriosis, and surgical arthroscopy. In this study, we developed a computer system, which is composed of a frame yabber, a sound board, a VCR control board, a LAN card and EDMS(endoscopic data management software. Also, computer system has controled peripheral instruments such as a color video printer, a video cassette recorder, and endoscopic input/output signals(image and doctor's comment). Digital endoscopic data management system is based on open architecture and a set of widely available industry standards, namely: windows 3.1 as a operating system, TCP/IP as a network protocol and a time sequence based database that handles both images and doctor's cotnments. For the purpose of data storage, we used MOD and CD-R. Digital endoscopic system was designed to be able to store, recreate, change, and compress signals and medical images.

To attain the rich and comfortable human living, much development and economic growth are needed. But the radical development destroys natural environments or resources, and also the life environments are destroyed. How to maintain the balance between development and environments forms an important problem. Since 1955, a great deal of damage has been done to human being by the pollution of air, water or noise in Japan, for example, Minamata-byo (1956), arsenical poisoning by mkil (1955), Cd-I taiitai-byo (1955), asthma by air pollution, etc. Now, there are over 100,000 sick persons suffering from pollution in Japan. To prevent the pollution, the first act was made 1967, the kind of which were defined as follow:air, water, soil, noise, vibration ground subsidence, and bad smell. Laws on these were established 1970∼1981, and the environments here ave gradually being improved. The mentioned above gituation necsesitates the measuring or chemical analysis of pollution data, but the many cost is necessary to obtain such data. The special environment measuring certifier was needed and the Measurement Law was amended 1974. Some comment will be given of the present condition of environmental measuring certifier.

Re-consultation on Marine Environment Impact Assessment (MEIA) says that business operators are then licensed back from the disposition authorities undergoing a consultation process to change business plans. Marine Environment Management Act has provisions(Article 94) with respect to a case where the scale of business, the period of business, reflects the basic plan, including a plan to change a variety of reasons. But increasingly diverse types of businesses and projects which are the subject of MEIA, As it appears that the vulnerability issues and the problem of the re-consultation. In this study conducted an analysis of the literature review and comment on the re-consultation report four years. In addition, it presents a check to the problem through concrete examples related to the re-consultation and proposes improvement measures.
