This study aims to determine the sensory acceptability of Gochujang added with persimmon syrup concentrate. To achieve this, Gochujang was blended with different concentrations of persimmon syrup concentrate (0%, 10%, 20%, 30%, 40%). Moisture contents and salinity decreased, whereas L, a, b values, pH level, and sugar contents and viscosity increased as the concentrations increased. As a result of an attribute difference test, glossiness and sweetness significantly increased with more concentrations. The acceptance test showed that 30% concentrate was the most preferable for taste, texture, and overall quality. In conclusion, the results indicate that addition of 30% persimmon syrup concentrate to Gochujang is optimal, providing good properties as well as reasonably high overall acceptability.

Objectives : The purpose of this study was investigating the differences in temperament, personality, and cognitive function among athletes and non-athletes, as well as differences within athlete groups participating in different-paced sports like baseball and basketball. Methods : A total of 57 professional basketball players, 51 professional baseball players, and 44 non-athletes subjected to temperament and characteristics inventory assessments and computerized neurocognitive function test. One-way analysis of variance (ANOVA) was employed to analyze the average differences in demographic characteristics, temperament, personality traits, and cognitive functions among the three groups, followed by Bonferroni post hoc tests. Comparisons between starters and non-starters within the athlete groups were conducted using the Mann-Whitney U test. Results : In the analysis of temperament, the basketball and baseball player groups exhibited higher reward dependence and persistence compared to the control group. Additionally, in the assessment of personality traits, both basketball and baseball player groups scored higher in self-directedness and cooperativeness compared to the control group, whereas self-transcendence scores were lower. In cognitive ability assessments, baseball and basketball players outperformed the control group in emotional perception tests. Both baseball and basketball players showed lower card movement counts compared to the control group. Conclusions : This study compared the differences in temperament, personality, and cognitive abilities between professional basketball and baseball players and non-athletes. These results provide valuable insights into the temperament, personality, and cognitive abilities of professional athletes, contributing important information for athlete development and coaching goals in the future.

The effects of learning using Information Communication Technology(ICT) on the students' scientific inquiry ability and science-related affective characteristics were analyzed in Earth History and Crust Movement units of science textbook for eighth graders. For this study, two classes of middle school second students in Chung-nam were selected and taught for six week under different teaching methods. One class is the test class taught with ICT applied teaching materials and the other class is the control class instructed by a conventional method. One week before the experiment, both classes were given tests on scientific inquiry ability and science-related affective characteristics, and they were tested again after the experiment. The results of scientific inquiry test showed statistically meaningful differences in the experimental class and the control class. The experimental class showed statistically meaningful difference in scientific inquiry test. Science-related affective characteristics test showed no statistically meaningful difference in the experimental class. Among three scientific science-related affective characteristics, especially the one fields of interests showed statistically meaningful differences which suggest that learning using ICT has a positive effect on the expanding of students' science-related affective characteristics.

The use of screening tests as part of a diagnostic work-up is common in domestic canine practice, but understanding of the diagnostic test characteristics and factors affecting diagnostic accuracy is not clear among clinicians. This article was aimed to provide clinicians with a better understanding on the selection of test kits and with a proper interpretation of test results using an example from heartworm(Dirofilaria immitis) studies. From the literatures, diagnostic accuracy varied depending on the kits: percent average sensitivity and specificity of ELISA antigen-detecting kits were DiroChek(Synbiotics, USA) 78.1 and 95.2, SNAP(IDEXX, USA) 66.3 and 98.1, and Solo Step(Heska, Switzerland) 69.5 and 97.5, respectively, while the values for three hematological methods(Modified Knott's, direct smear and capillary tube) ranged from 38.4 to 81.8% and from 96.9 to 100%, respectively. Furthermore, it was also reported that the prevalence of heartworm disease in domestic dog populations varied depending on the regions studied: 2.5-22.8% for microfilarial test and 2.2-66.3% by ELISA. The values of predictive values for positive(PPV) and negative(NPV) provide useful information to clinicians on the probability of heartworm infection, but the PPV and NPV are greatly dependent on the heartworm prevalence. This suggests that PPV or NPV values of a test should be interpreted carefully in different clinical settings. Practical methods on the interpretation taking into account heartworm prevalence were discussed.

The purpose of this study was to analyse the qualitative and quantitative characteristics of paper-pencil tests for exploring its appropriateness as a selection tool of the gifted in science. For this purpose, we developed two (internal and external) item analysis frameworks, and applied these frameworks to analyse qualitative characteristics. Also, we analysed the relationship between two characteristics. The results of analysing qualitative characteristics revealed that the portion of items with acceleration context exceeding middle school curriculum level was relatively large, which caused low content validity. Furthermore, there was considerable deviation in content and context by subject matter and year, which caused test unstability. Items measuring knowledge domain was the most prevalent, and too much weight on data interpretation & analysis domain in inquiry process skills. In case of creativity test, the portion of items measuring convergent thinking was much larger than that of divergent or associative thinking. Most of these items were represented by using pictures and tables rather than using graphs. Item types of multiple-choice and short answers were superior to essay types. Discrimination index, on the whole, was appropriate (above 0.3), but item difficulty showed a vast deviation ($0.01{\sim}0.90$). Correlation coefficients among subject matters and test tools were very low, and test reliabilities were also low. Low item difficulty & high discrimination index item types were distinguishable. Items with acceleration context were more discriminating than enrichment context. Implications of developing quality paper-pencil test items in the selection of gifted students are discussed.

Product distribution and consumption in the military is difficult due to unique contracts and supply systems. It is difficult to change suppliers immediately when quality problem is encountered. Due to these special circumstances, the quality of products must be thoroughly controlled. Sesame oil is used to increase the taste and nutrition of food, but it is more expensive than other cooking oils. Oil producers may blend other cooking oils with sesame oil to make higher profits, so it has become important to identify good and bad products. In this study, pure sesame oil and blend oils were compared by analyzing their smell, taste, chemical components, and near infra-red spectra to determine quality differences between them.

Gangjeong was prepared by adding Lentinus edodes to improve quality of the gangjeong and to give some functional properties. Contents of the crude protein and ash increased with increasing amount of L. edodes, while carbohydrate contents decreased. As the ratio of mushroom in gangjeong increased, lightness and yellowness in Hunter's color value tended to decrease. In terms of texture, 20% and 30% contents of L. edodes made no significant differences in gumminess, brittleness, cohesiveness, and springiness compared to control, whereas hardness showed no difference to control. Gangjeong with 30% L. edodes obtained the highest scores in quality and sensory characteristics.

The purpose of this study is to develop a Science Ethicality Test (SET) to measure students' science ethics. To secure the validity and reliability of the SET, the authors have applied Rest's Four Components Model (FCM). To develop the SET, authors have conducted the following procedures: analysis of the Korean Youth Moral Test (Kim & Lee, 2012), alteration of the KYMT; and development of the SET. Rest's FCM is consisted of moral sensitivity, moral judgment, moral motivation, and moral character. The SET is consisted of ethical sensitivity, ethical judgment, ethical motivation, and ethical character with each factor having its own elements. To secure the validity and reliability of SET, authors requested a validity assessment from five experts (two evaluators are science education experts, two others are ethics education experts, and one evaluator is a scientist), and surveyed 599 elementary school students. As a result, SET proved high levels of validity and reliability.

This paper was to examine the effects of university-based science gifted education program on scientifically gifted students' science problem finding ability and cognitive-affective factors. For this study, 69 scientifically gifted students with previous Silted education experiences at the university-based science gifted education centers and 91 scientifically gifted students without any previous gifted education experiences were compared. Both groups of students were currently enrolled at a specialized science high school. To compare both groups, scientific problem finding ability, science anxiety, science related attitude, self-efficacy, intrinsic motivation, test anxiety, cognitive strategies, and self-regulation were measured. The results indicate that there was no significant difference on scientific problem finding ability between these two groups. The comparison between the past and now in the aspects of variables observed in the study showed that both groups of students were decreased in the science anxiety and self-efficacy. But the test anxiety was significantly increased compared to the past in both groups. Implications of the study were discussed in depth.
