The effects of moisture content on non-fracture dynamic properties and fracture gel quality of Pacific whiting surimi were investigated to determine their relationships. Surimi samples were tested at various moisture contents (75, 78, and 81 %). Torsion test showed that shear stress decreased rapidly and strain values decreased gradually as moisture concentration increased. Dynamic storage modulus (G') also decreased as moisture content increased. A strong positive correlation ($R^2=0.90$ to 0.99) was found between the G' measured at temperatures between 10 and $45^{\circ}C$ and fracture stress values. The results indicate that dynamic rheological measurements could be used as a tool for early gel quality assessment.

The control performance of a chemical process is determined by process structure as well as the performance of controllers. Therefore, the concept of“controllability”should be introduced in the early design stage. Structural information makes controllability assessment possible by giving insights on the pathways of disturbances in the process. In this study, a simple procedure to evaluate controllability is suggested to screen out design alternatives using relative order analysis and structural decomposition. The effectiveness of the proposed method was validated by comparing the results with the case of dynamical simulation.

In this paper a computer aided analysis method is proposed for durability assessment in the early design stages using dynamic analysis, stress analysis and fatigue life prediction method. From dynamic analysis of a vehicle suspension system, dynamic load time histories of a suspension component are calculated. From the dynamic load time histories and the stress of the suspension component, a dynamic stress time history at the critical location is produced using the superposition principle. Using linear damage law and cycle counting method, fatigue life cycle is calculated. The predicted fatigue life cycle is verified by experimental durability tests.

This study investigated the quality of after-school programs focused on artistic-physical activities, children's emotional regulation and social competence. The subjects were 224 elementary school children (1st through 6th grades) and 41 teachers. The measures were questionnaire(after-school activities), Assessment Profile for Early Childhood Programs(school-age), the Emotional Regulation Scale. and the Social Competency Scale. The data were analyzed by Cronbach's a, frequency, percentile, mean, and t-test. The results indicated that emotional regulation and, social competence were significantly different according to the quality of after-school programs： Children in a higher group of curriculum quality and interaction with teacher had better emotional regulation than did children in a lower group. Children in a higher group of curriculum quality and scheduling had better social competence(leadership and competence) than did children in a lower group.

Ornithine transcarbamylase (OTC) deficiency is the most common inborn error of urea cycle metabolism; it is inherited in an X-linked manner. The OTC catalyzes the third step of the urea cycle, the conversion of ornithine and carbamyl phosphate to citrulline. Deficiency of OTC leads to the accumulation of ammonia, causing neurological deficits. In most affected hemizygote males, OTC deficiency manifests as hyperammonemic coma that often leads to death in the newborn period, and those who recover from the coma may be neurologically impaired due to the sequelae of the hyperammonemic encephalopathy. In some, late-onset manifestations develop. We report a male neonate with early onset OT deficiency that had apnea and was comatous. On mutation analysis using DNA sequencing after polymerase chain reaction (PCR) amplification of the 10 exons, deletions of 10 bases in codon 285, causing a frame shift was detected in exon 8. The mother and a sister were diagnosed as female carriers. Therefore, genetic counseling and the risk assessment could be provided to the family.

There have been very few reports in the literature of Guillain-Barr$\acute{e}$ syndrome (GBS) after spinal surgery. We present a unique case of GBS following spinal fusion for thoracic vertebral fracture. The aim of this report is to illustrate the importance of early neurological assessment and determining the exact cause of a new neurological deficit that occurs after an operation.

This paper presents a systematic study for control loops in the induction motor drive system employing a load commutated current source inverter (LCCSI) which has appeared since the early 1980's, and their effects on the dynamic stability of the system. A set of dq equations which amalgamate the overall system is developed, and from the equations it is revealed that the steady state characteristics of the LCCSI-induction motor system are between VSI and ASCI. When the speed control loop is constructed without a speed sensor, the evaluation of the pole/zero locations and the assessment of the stability for the added loops are investigated. We also show that the V/F loop is essential in this type of drive without the speed sensor.

A program of ecosystem conservation fund was proposed by the Ministry of Environment in Korea and has been supposed to come into force in early 2001. However, currently the program is withheld because there are strong objections to it for several reasons. The prime purpose of this paper is to analyze the reasons and problems involved in the program, to suggest some guidances to revise the program, and to design a new program by using a multiattribute index based on environmental significance. We found that there are two major problems of the program: first, inequity in choosing those whom the fund are levied on; second, irrationality of the way the fund are imposed. The paper also provides a simulation study to analyze the effects of four scenarios concerning feasible alternatives. We argue that natural resource damages caused by development works cannot be fairly prevented by the existing environmental impact assessment system only and should be used in harmony with the new system.

Often arrangement for effective product assessment and audit have not been completely satisfactory. The underlying reasons are: (a) The lack of early evidence of new unit quality. (b) The collection and processing of data. (c) Ineffective data analysis techniques. (d) The variability of information on which decision making is based. Because of the nature of the product the essential outputs from an affective QA organization would be: (a) Confirmation of new unit quality. (b) Detection of failures which are either epidemic or slowly degradatory. (c) Identification of failure cases. (d) Provision of management information at the right time to effect the necessary corrective action. The heart of an effective QA scheme is the acquisition and processing of data. With the advent of data processing for quality monitoring becomes feasible in an automotive testing environment. This paper shows how the method enables us to use Automotive Testing data for the cost benefits of QA management.
