This study investigated the preparation of seasoned anchovy sauce (SAS) and its functional characteristics by using aminopeptidase active fractions (AAFs) derived from squid Todarodes pacificus hepatopancreas as a bitter taste improver. As the base of the SAS, a hydrolysate (AAAH) prepared by continuously treating raw anchovies with Alcalase-AAF was used. The high-performance liquid chromatography profile of the AAAH suggested that the action of AAFs decreased the hydrophobicity of the N-terminal peptide related to bitterness in the protein hydrolysates. SAS was prepared by blending with the AAAH and other ingredients. The crude protein (2.5%), carbohydrates (18.4%), amino acid-nitrogen (1,325.1 mg/100 mL), and total free and released amino acids (FRAAs, 700.2 mg/100 mL) of SAS were higher than those of commercial anchovy sauce (CAS). Sensory evaluation revealed that SAS was superior to CAS in flavor, color, and taste. The main FRAAs of SAS were glycine (16.8%), alanine (13.2%), glutamic acid (7.8%), and leucine (7.3%). The amino acids that had a major influence on the taste according to the SAS taste values were glutamic acid, aspartic acid, alanine, and histidine. The angiotensin-converting enzyme inhibitory (2.21 mg/mL) and antioxidant activities (3.58 mg/mL) of SAS were superior to those of CAS.

The sub-micron particles of poly ($\gamma-glutamic$ acid) (PGA) containing lysozyme have been prepared using supercritical antisolvent (SAS) precipitation process at various experimental conditions such as pressure, temperature, inner diameter of nozzle, and concentration. As overall results of the application of SAS process to this system, the smaller size powder has been produced as (i) increasing pressure, (ii) decreasing temperature, (iii) decreasing the inner diameter of nozzle, and (iv) decreasing the concentration of PGA and lysozyme. It is found by means of FT-IR analysis that during SAS process, the composition has changed from the original composition of PGA : lysozyme=50 : 50 into PGA : lysozyme=33 : 67 at final product powder. It means that PGA has higher solubility for the mixed solvent of carbon dioxide and dimethyl sulfoxide (DMSO). Due to such difference of solubility, this particle forms the core-shell structure of which the core consists mainly of lysozyme. It is also found that the residual DMSO amount of $7.8\times10^{-3}wt%$ exists inside the powder.

Spirituality has been found as a factor that may influence an individual's health and response to illness and dying. The purpose of this study was to assess the reliability and validity of the Korean version of the Howden's Spiritual Assessment Scale(SAS). The SAS was developed based on the attributes of spirituality and constructed with 28 items, 4 subscales. The translation involved four steps : translation into Korean, checking agreement, back translation into English, and arriving at a consensus. Psychometric evaluation was done on 222 nurses from five hospitals. All responses were voluntary and anonymous. The Cronbach's alpa coefficient for internal consistency was .928 for the total 28 items and .700${\sim}$.805 for subdimensions. Item- total correlations ranged from .36${\sim}$.68. Principal Component Factor Analysis with Varimax Rotation yielded four factors with four or more items each loading at .40 or higher. These factors explained 51.3% of the total variance. The items clustered in this study were almost identical with initial scale. There was positive correlation(r=.648, p=.0001) between SAS and Ellison & Paloutzian's Spiritual Wellbeing Scale and negative correlation(r=-.418, p=.000) with Pines' Burnout Scale which indicate convergent and discriminant validity. In conclusion, this tool can be effectively utilized for assessing spirituality in Korea.

Many users have made the most often use of the SAS system in statistical data analysis all over the world. But it is difficult to use the grand procedures and language of the SAS system. Therefore the side of program development has changed in the graphic-oriented and menu-centered way like SASj ASSIST, SASjINSICHT after a version 6.08 turned into the Window environment. A biplots is a multivariate data analysis technique that graphically describes both relationships among the multidimensional observations and relationships among the variables. But there were not the procedure and graphic interface for a biplots algorithm in the SAS system. In this paper, there are two objects. First, we supply users with the convenience of the environment of CLI, which is constructed with SASj AF and SCL, to solve the problem that we have programed a biplots algorithm with the SASjIML one by one. Second, we reflect the current of the Information Age which means the spread of various kinds of system construction to extract useful information from data with the help of the development of hardware and software.

Purpose: The main causes of chronic neck pain (CNP) are wrong postures and degenerative changes. This study investigated the effects of specific exercise on elderly women with CNP. Methods: 29 elderly women who complain of CNP were classified into experimental group (14) and control group (15). The experimental group was treated with specific exercise and minimal conventional therapy, whereas the control group was treated only with conventional therapy. Then the effects on the visual analogue scale (VAS), neck disability index (NDI), self-rating anxiety scale (SAS), Korean form of geriatric depression scale (KGDS), and range of motion (ROM) were compared between the two groups. Results: The experimental group showed significantly improved results in VAS, NDI, SAS, KGDS, and ROM after intervention (p<0.05), as did the control group (p<0.05). The comparison of changes in the experimental group before and after intervention showed superior results in the SAS, NDI, and ROM (flexion, rotation, lat. flexion) results when compared with the control group (p<0.05). Conclusion: Specific exercise is effective in the improvement of SAS, NDI, and ROM for elderly women with CNP.

The human head is identified as the body region most frequently involved in life-threatening injuries. Extensive research based on experimental, analytical and numerical methods has sought to quantify the response of the human head to blunt impact in an attempt to explain the likely injury process. Blunt head impact arising from vehicular collisions, sporting injuries, and falls leads to relative motion between the brain and skull and an increase in contact and shear stresses in the meningeal region, thereby leading to traumatic brain injuries. In this paper the properties and material modeling of the subarachnoid space (SAS) as it relates to Traumatic Brain Injuries (TBI) is investigated. This was accomplished using a simplified local model and a validated 3D finite element model. First the material modeling of the trabeculae in the Subarachnoid Space (SAS) was investigated and validated, then the validated material property was used in a 3D head model. In addition, the strain in the brain due to an impact was investigated. From this work it was determined that the material property of the SAS is approximately E = 1150 Pa and that the strain in the brain, and thus the severity of TBI, is proportional to the applied impact velocity and is approximately a quadratic function. This study reveals that the choice of material behavior and properties of the SAS are significant factors in determining the strain in the brain and therefore the understanding of different types of head/brain injuries.

The objective of this work is to design Surface Antenna Structure (SAS) and investigate fatigue behavior of SAS that is asymmetric sandwich structure. This term, SAS, indicates that structural surface becomes antenna. Constituent materials are selected considering electrical properties, dielectric constant and tangent loss as well as mechanical properties. For the antenna performance, SSSFIP elements inserted into structural layers were designed fur satellite communication at a resonant frequency of 12.5 GHz and final demonstration article was $16{\;}{\tiems}{\;}8$ array antenna. From electrical measurements, it was shown that antenna performances were in good agreement with design requirements. In cyclic 4-point bending, flexure behavior was investigated by static and fatigue test. Fatigue life curve of SAS was obtained. The fatigue load was determined experimentally at a 0.75 (1.875kN) load level, Experimental results were compared with single load level fatigue life prediction equations (SFLPE) and in good agreement with SFLPE. SAS concept is the first serious attempt at integration fur both antenna and composite engineers and promises innovative future communication technology.
