  • 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.

  • 라이소자임이 내포된 폴리감마글루탐산(PGA)의 서브-마이크론 크기의 미세입자를 압력, 온도, 노즐내경, 농도 등을 변화시켜가면서 초임계 반용매 침전법 (SAS)으로 제조하였다. SAS법의 전체적인 결과는 압력이 클수록, 온도가 낮을수록, 노즐 내경이 작을수록, 농도가 묽을수록 작은 입자가 얻어졌다. FT-IR로 분석한 결과, 본래 초기의 PGA:라이소자임:50 : 50의 조성비는 SAS 공정을 거치면서 최종 분말 입자 내에서는 33 : 67로 변화하였다. 이것은 PGA가 라이소자임보다 탄산가스/디메틸설폭사이드(DMSO) 혼합용매에 더 높은 용해도를 가지기 때문인 것으로 추측된다. 또 이러한 용해도 특성 때문에 생성 입자는 핵-껍질 구조를 갖고 있으며, 핵 부분은 라이소자임이 구성하는 것으로 여겨진다. 생성된 분말 입자 내에는 $7.8\times10^{-3}wt%$의 농도로 미량의 DMSO가 잔존하고 있음이 밝혀졌다.

  • 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.

  • 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.
