  • This study was investigated for the purpose of obtaining basic data for application to the canning process of salt-fermented anchovy Engraulis japonica fillet using tomato paste. The salt fermented anchovy fillet was prepared by fermenting anchovy fillet with salt 15% at $5^{\circ}C$ for 15 days and then cold air drying the salt-fermented anchovy fillet for 1 h at $16{\pm}1^{\circ}C$. The dried salt-fermented anchovy fillet 85 g was filled with 60 g of tomato paste sauce (tomato paste 42%, gum guar 1.0%, salt 2.0%, starch syrup 2.0%, cooking wine 1%, water 52%) and seamed by vacuum seamer in 301-3 can, then sterilized at Fo 9 and 11 min in a steam system retort at $121^{\circ}C$, respectively. The factors such as chemical composition, pH, total volatile basic nitrogen (TVB-N), amino-N, color value (L, a, b), texture profile, thiobarbituric acid (TBA) value, sensory evaluation and viable bacterial count of the canned salt-fermented anchovy fillet were measured. Texture value of the product sterilized at Fo 11 min was higher than at Fo 9 min condition. In both sterilized cans, the viable bacterial counts were not detected. There was no remarkable difference in physicochemical between sterilization conditions. As a result of sensory evaluation, most sensory evaluation inspector judged that it was difficult to distinguish the sensory difference of both products sterilized at Fo 9 min and at 11 min. The results showed that sterilization of Fo 9 min was more desirable than that of Fo 11 min to prepare canned salt-fermented anchovy fillet using tomato paste sauce, because this condition is more economical.

  • Physicochemical and sensory characteristics of turnip pickles added with chitosan and/or beet water extract were investigated. Turnip root slices (4${\times}$1${\times}$0.5 cm) were salted with NaCl and CaCl$_2$, soaked into pickling solution, and then stored at 2$0^{\circ}C$. Throughout the whole storage periods, pH, acidity, saltiness and soluble solid content of three pickles (C, turnip pickle; CC, turnip pickle+chitosan; CBC, turnip pickle+chitosan+beet water extract) ranged to 3.1 ∼ 3.5, 1.5 ∼ 1.7%, 0.5 ∼ 0.7% and 24.5 ∼ 28.5$^{\circ}$Brix, respectively. There were no significant differences between three pickles in saltiness, anthocyanin and reducing sugar content. However, acidity and hardness of CC and CBC were higher than those of control C throughout the storage time. While Hunter's a value of CBC was higher than those of CC or C. Sensory results showed that the best edible time was the 14th day of storage, and at that time, scores of CC and CBC were higher in over-all preference (7.8 and 8.4) than those of C (6.1), and CC and CBC maintained good sensory qualities until 28th day of storage, compared to C (p<0.05).

  • Although instant coffee is less palatable than freshly brewed coffee, it is widely consumed primarily due to its convenience. Frequently, instant coffee is consumed in the form of a coffee-mix. It contains coffee creamer or dried skim milk, and sugar in addition to soluble coffee. The aim of this study was to investigate the volatile aroma compounds (VACs) of instant black coffee mixed with coffee creamer or dried skim milk by Gas Chromatography-Headspace-Solid Phase Microextraction (GC-HS-SPME) and sensory evaluation. A total of 16 different coffee samples including instant black coffee and coffee mixes with coffee creamer or dried skim milk, were chosen for this study. The coffee samples contained several common VACs such as pyrazine, pyridine, and pyrrole. Sensory evaluation indicated that the flavor intensity of coffee mix was less pronounced than that of instant black coffee alone. Coffee creamer and skim milk had little distinctive aroma per se; however, they significantly contributed to the flavor profile of coffee mixes, suggesting that coffee creamer and skim milk acted as flavor modifiers in coffee mix.

  • Texture properties of a Korean rice cake (Karedduk) added with carbohydrate materials after 0, 2, 6, 24 and 30 hrs of storage at $5^{\circ}C$ were investigated using textural characteristics and sensory descriptive analysis. Carbohydrate materials such as powdered sugar, trehalose, fructooligosaccharide (95%), isomalto, healtholigo, and galactooligosaccharide (50%) were added in 0, 1, 5 and 10% levels to dry rice flour. The texture profile analysis by Texture Analyzer revealed that adhesiveness and cohesiveness of the Korean rice cake (Karedduk) added with carbohydrate materials were similar to those of the control in trends, while hardness was low compared to the control except for fructooligosaccharide (95%) 5% and healtholigo 1% addition. The hardness and sweetness by sensory characteristics were significantly different compared to the control. Instrumental hardness was correlated with sensory hardness. Lastly, the Korean rice cake (Karedduk) added with carbohydrate materials except fructooligosaccharide (95%) 5% and healtholigo 1% addition was effective in delaying retrogradation.

  • We investigated the sensory and quality characteristics of gambas al ajillo retort foods with nondigestible maltodextrin (trial gambas) compared with commercially available frozen gambas al ajillo (control). Trial gambas demonstrated approximate compositions of 75.8% moisture, 11.3% protein, 5.8% lipid, 1.7% ash, and 5.4% carbohydrates, indicating lower lipid and carbohydrate contents but higher moisture, protein, and ash levels than that of the control. Sensory assessments conclusively established the superior overall acceptability of trial gambas over the control. Trial gambas exhibited a total amino acid content of 9.62 g/ 100 g, surpassing the 5.39 g of the control. The major amino acids, such as lysine, leucine, arginine, aspartic acid, and glutamic acid, contributed significantly to its enhanced nutritional profile. Mineral analysis revealed higher calcium, phosphorus, magnesium, and iron levels in trial gambas and lower potassium levels than that in the control. Fatty acid profiling identified 18:1n-9 (67.8%) and 16:0 (11.9%) as the predominant fatty acids, in concordance with the control. This study substantiates trial gambas with the health-oriented preferences of the MZ generation while presenting superior sensory and quality attributes compared with the control.

  • Introduction : Occupational therapists commonly use clinical observation to assess neuromuscular function witch is a fundamental component of sensory integration function. Clinical Observation of Motor and Postural Skills (COMPS) is a standardized assessment with seven items and used to screen if a child's problem is due to neuromuscular and sensory integration system. However, developmental standard of the test need to be validated with Korean children. Objective : This study is purposed to propose developmental standard of the COMPS for Korean children. Method : Seven to nine years old students (76 male and 70 female) participated in this study. In order to find out any difference by gender and age, the data was analyzed using t-test and ANOVA. Results : There is no significant difference by gender for all other items except Prone Extension Position (PEP). There is significant difference between children who are 7 years old and those who are 9 years old for Slow Motion(SM), Finger-Nose Touching (FNT), Asymmetrical Tonic Neck Reflex (ATNR), Supine Flexion(SF). There is also significant difference between those who are 8 years old and 9 years old for SM, FNT, ATNR. However, there is no significant difference between those who are 7 years and 8 years old. Conclusions : This study examines any difference in neuromuscular characteristics by age among school-aged children, based on the COMPS. The result of this study will provide a good evidence to establish developmental standard of COMPS for Korean children. It issuggested to continue further standardization work of the COMPS in order to establish a developmental standard for Korean children.

  • Effects of supplemental levels of Bomboo vinegar(BV) on growth performance, serum profile and meat quality in 15 Korean native Hanwoo cows was investigated. Concentrate diet was supplemented with Bamboo vinegar with 3% and 6% of the diet. Daily weight gain was increased slightly at 3% BV, but it was decreased in 6% BV. Feed intake was decreased(P<0.05) at 6% BV. Glucose concentration of serum profile was decreased(P<0.05) at 3% and 6% BV. Total protein and cholesterol concentrations were increased(P<0.05) at 3% and 6% BV. BUN concentration was increased(P<0.05) at 3% BV. In carcass characteristics the longissimus muscles of all BV treatments showed no significant(P<0.05) effects, but back fat thickness was decreased significantly(P<0.05) in 6% BV. Marbling score was increased significantly(P<0.05) at 3% BV, thus improving the meat quality. Cut meat production was not difference by treatment. Crude fat content of proximate chemical composition in longissimus muscle was increased(P<0.05) in 3% BV. Shear force and cholesterol contents were decreased(P<0.05) in 3% and 6% BV. The 16:0 of fatty acid composition in longissimus was decreased(P<0.05) whereas 18:1 was increased(P<0.05) at 3% and 6% BV. The composition of saturated fatty acids(SFA) was decreased(P< 0.05), whereas unsaturated fatty acids(USFA) was increased(P<0.05) in 3% BV. Odor and appearance of sensory evaluation were not difference by treatment. Taste was improved significantly (P<0.05) in 3% and 6% BV with the peculiar and savory taste of Hanwoo being more emphasized. The results of this experiment indicated that 3% BV improved the marbling score and crude fat content, decreased the shear force and cholesterol contents, increased the USFA composition, and improved the taste of sensory evaluation in Korean native Hanwoo cows.

  • The purpose of this study was to evaluate the biological activities and quality properties of macaroons made with GABA rice powder and xylose. GABA rice powder was added to macaroons at weight percentages of 0, 2.5, and 3.5%. Hunter's color values ($L^*$, $a^*$, $b^*$), total sugar contents, total phenolics, ABTS and DPPH radical scavenging activities, textures, and sensory characteristics supplemented with different xylose and GABA rice powder contents were measured. As the ratio of GABA rice powder in macaroons increased, total phenol contents and ABTS and DPPH radical scavenging activities increased. In the texture profile analysis, fracturability and brittleness were lower as GABA rice powder content increased. In the sensory evaluation, significant differences (p<0.05) were observed in color, sweetness, texture, and overall acceptability depending on the addition of GABA rice powder to macaroons. Overall qualities of macaroons were different from GABA rice powder and xylose added ones. Therefore, xylose and GABA rice powder may be used to make healthy macaroons.

  • This study aimed at comparing the storage stability, fatty acids profile, volatile flavor compounds and eating quality of Hanwoo beef longissimus thoracis (LT) muscles between two marbling morphological groups (fineness and coarseness). The 1+ grade Hanwoo LT muscles were measured for marbling fleck morphology at the 13th thoracic vertebrae location by using computerized image analysis. Results reveal that both marbling groups had similar proximate composition (protein, fat, moisture and collagen), color and technological quality traits (p>0.05). However, the coarse marbling group presented greater C18:2n6 and polyunsaturated fatty acids contents compared to the fine marbling group (p<0.05). Furthermore, the fine marbling group presented lower volatile basic nitrogen (VBN) and 2-thiobarbituric acid reactive substance (TBARS) contents compared to the coarse marbling group after 14 d storage (p<0.05). Also, higher amounts of C18:2n6 oxidation-derived volatile compounds such as hexanal and 3-ethyl-2-methyl-1,3-hexadiene, were found in the coarse marbling group. In term of sensory aspects, the finely-marbled group received higher scores of flavor and taste compared to the coarse marbling group (p<0.05). Overall, the marbling flecks morphology partially showed its effects on the storage stability, fatty acids profile and eating quality of the 1+ grade Hanwoo beef LT muscle.

  • Our conclusions for function evaluation tools of Stroke patients are as follows. 1. Evaluating tools of Activities of Daily Living, Katz Index, Barthel Index, Modified Barthel Index have high validity and reliability because of ease of measuring, high accuracy, consistency, sensitivity and sufficient stastistics, but they mainly measure motor function except sense, mentation, language, and social conception. Therefore cerebrovascular disease and brain injury in trauma patients with lacked acknowledgement and sensation, we are not able to apply these tools. 2. PULSES Profile is a useful scale for measuring the patient's over-all status, upper and lower limb functions, sensory components, excretary functions, and intellectual and emotional adaptabilities. It is recognized as a good, useful tool to evaluate patient's whole function. 3. Motor Assessment Scale was designed to measure the progress of stroke patients. The scale was supplemented with upper arm function items. We believe that the Motor Assessment Scale could be a useful evaluation tool with inter-rater reliability ,test-retest reliability. 4. The existing evaluation tools, Katz Index, Barthel Index, Modified Barthel Index, PULSES Profile, Motor Assessment Scale, mainly measured the rehabilitational motor function of sequela of cerebrovascular patients. On the other hand CNS & INH stroke scale can measure cerebrovascular disease patient's neurologic deficits and over-all stautus, which are recognition ability, speech status, motor function, sensory function, activities of daily living. Those scales have been recognized as useful tools to measure function of cerebrovascular disease patients and have increased in use. 5. Every function evaluation tool was recognized to have some validity and inter-rater, test-retest reliability in items of each evaluation tool and total scores of each evaluation tools, but it is thought that none of these scales have been fully validated and proved reliable. Therefore afterward, the development of a highly reliable rating system may best be accomplished by a careful comparison of several tools, using the same patients and the same observers in order to choose the most reliable items from each. 6. Ideal evaluation tools must have the following conditions; (1) It should show the objective functional statues at the same time. (2) It should be repeated consecutively to know changed function status. (3) It should be easy to observe the treatment program. (4) It should have the same result with another rater to help rater exchange information with treatment team members. (5) It should be practical and simple. (6) The patient should not suffer from the observer.
