The objective of this study was to investigate Alaska pollock Theragra chalcogramma roe grade distribution among blocks and its nutritional components by grade. M grade roe was predominantly distributed in blocks labeled as L and M (52.1 and 82.8%, respectively), and S grade roe was mainly found in blocks labeled as S (98.6%). Products labeled as containing KB and KC grade roe contained 77.1 and 65.5% normal roe, respectively. Among the five roe grades (L, M, S, G, and Off), total amino acid content was higher in normal roe than in abnormal roe. The major amino acids found in normal roe were leucine, aspartic acid, and glutamic acid, whereas G and Off grade roe contained leucine and glutamic acid, but not aspartic acid. The calcium, phosphorus, potassium, and iron contents of the five roe grades were within the ranges 13.0-20.0, 314.4-392.0, 124.1-157.7, and 1.7-2.2 mg/100 g, respectively. The five roe grades contained total fatty acid contents of 765-1,252 mg/100 g, with no significant differences among grades. The major fatty acids were 16:0, 18:1n-9, 20:5n-3, and 22:6n-3.

The purpose of this study was to evaluate the perception and preference of Kimchi among the elementary school children. The survey was conducted via questionnaire to 439 elementary school children(224 males and 215 females) who lived in Seongnam. 77.2% of the surveyed children had an affirmative opinion of Kimchi intake. Children regarded Kimchi as traditional, nutritious, healthy, fermented and delicious food. It also revealed that the higher grade($4{\sim}6$ grade) students were more awareness in Korean traditional fermented healthy food as for Kimchi than the lower grade($1{\sim}3$ grade) students. They should eat Kimchi mainly because Kimchi is good for health(82.9%), nutritious food(62.9%), our traditional food(58.3%), and delicious food(41.5%). 73.9% of the children responded that the parents influenced on their consumption of Kimchi, but 16.5% of the children answered that their parents did not meddle. 67.3% of the children liked Kimchi, whereas 5.3% of them disliked it. The preference of Kimchi was significantly higher for lower grade students than for higher grade students. The main reason liking Kimchi was hot taste(60.8%) of Kimchi, and then texture of chewing(59.0%), taste of freshness (29.2%), cool taste(28.7%), and peculiar taste(26.9%) of Kimchi in order. The majority reasons for dislike the Kimchi were salty taste, hot taste, not eat oftenly, smell, appearance of Kimchi in order. The hot taste of Kimchi was the number one reason of their diskike of Kimchi, especially for lower grade students and female students, and it was the most important reason for those also like Kimchi. The children preferred the a little hot taste of Kimchi, properly fermented Kimchi, medium amount of seasoning in Kimchi, and any parts of Baechu in Kimchi.

This study was designed to identify factors affecting polyclinic (clinical practice) during COVID-19. Fourth-year medical students at K Medical University in Daejeon, South Korea were recruited, and 64 medical students ultimately agreed to participate in a survey about polyclinics in a regional emergency center over 4 weeks. Satisfy answers for 5^th grade and 6^th grade was 15 (53.6%) and 13 (46.4%) respectively. Dissatisfy answers of observation of the ICU for 5^th grade and 6^th grade was 10 (27.8%) and 26 (72.2%) respectively. Thus, there were more satisfy answers in 5^th grade and less satisfy answers in 6^th grade(p<0.05). Based on the results of confirming significance for regression coefficient, several factors influencing the polyclinic were identified, and the following categories showed statistical significance (p<0.05): for 6^th grade, satisfy answers of the clinic hours showed 3.656 times more than dissatisfy answers, exempt from the operation room showed 21.596 times more than dissatisfy answers, observation of the intensive unit care (ICU) showed 0.054 times less than dissatisfy answers, and cares of the COVID-19 patients showed 6.962 times more than dissatisfy answers. We suggest that hybrid or virtual medical education such as the polyclinic utilizing standardized patients (SP) or augmented reality (AR) technologies at the virtual hospital or the real hospital. More medical students would be encouraged to participate the problem-based learning (PBL) or team-based learning (TBL) in so-called 'hybrid or virtual' polyclinic.

The purpose of this study is to examine the vertical and horizontal continuity between grades and publishers, respectively, by analyzing the readability of reading passages included in English textbooks for 5th and 6th grades of elementary school. In order to do so, a corpus was constructed with the reading passages contained in 10 textbooks, and the reading passages in each textbook were analyzed through Coh-Metrix. Also, it was examined whether there was a statistically significant difference between grades and publishers in readability through one-way ANOVA. The results are as follows. First, as a result of analyzing the difference in readability between publishers within the same grade, there was a statistically significant difference between fifth-grade textbooks in the L2 readability index. Second, as a result of analyzing the vertical continuity between grades within the publisher, the difficulty of textbook A was higher in grade 6 than grade 5 based on FRE and FKGL, which showed a statistically significant difference. On the other hand, when L2 readability was used as the standard, the difficulty of textbook B was lower in 6th grade than in 5th grade. This result seems to be because FRE and FKGL calculate readability based on sentence and word length, whereas L2 readability is based on content word overlap, word frequency, and syntactic similarity of sentences.

In the current information and knowledge-based society, a nation's economy power heavily depends on IT-related industry and technology. In this sense, most countries are trying to foster IT industry by developing new and innovative IT technologies. Traditionally, only a few talented persons have been leading the whole IT industry. Thus, it is very important and necessary to identify and support the gifted children in IT in early ages for development of IT industry. The purpose of this paper is to investigate study performance of the gifted children in IT for different grades. Our research is focused on especially 4th grade students, 5th grade students, and 6th grade students in elementary schools. Among various abilities of the gifted children in IT, in this paper, we are interested in programming ability and logical thinking ability. To our best knowledge, there is no research work on study performance depending on different grades of the gifted children in IT. For this purpose, the gifted students in gifted science education center attached in a university at Seoul Metropolitan Area are selected and their test scores for 8 years were collected and analyzed. The statistical analysis results show that there is no significant difference among 4th grade students, 5th grade students, and 6th grade students for programming ability and logical thinking ability. We hope that this result can help suggest and propose study contents, curriculum, principles and laws for the gifted education in IT.

This study sought to examine the impact of reading ability and vocabulary at age 5, as well as analyzing the impact which children's gender, parental education level and family income level has on reading comprehension ability and vocabulary at the first grade level in primary school. The study also sought to compare the characteristics of the results obtained in Korea and Japan on this particular research topic. For the Korean part of the study, 328 first grade Korean children, who had participated in the initial testing as five-year olds and agreed to participate in the longitudinal study were tested; whereas in Japan, 215 students were tested. The study results indicated that, in the case of Korea, reading comprehension ability in the first grade was affected by vocabulary and reading abilities at age 5, gender, as well as the mother's education level, in that order. In Japan, it was affected in the order of vocabulary, gender, and father's education level. In terms of first grade vocabulary, in the case of Korea, it was affected in the order of vocabulary and reading ability at age 5 and father's education level; whereas in Japan, it was affected in the order of vocabulary, gender, and reading ability. In both Korea and Japan, at age 5, vocabulary was shown to have a more significant impact than reading ability on both of language ability and vocabulary in the subsequent primary school period. As such, it can be seen that more interest should be shown not only in the ability to read at age 5 but also in expanding the vocabulary of children at this age through appropriate interaction and support.

Objective : This study is aimed to assess the clinical outcome in early and minimally invasive surgery using incision for the patients with poor grade aneurysm. Methods : The authors retrospectively reviewed all 46 poor grade patients of Hunt and Hess[H-H] grade IV and V who suffered aneurysmal subarachnoid hemorrhage[SAH] between 1999 and 2004. All 35 patients harboring 43 aneurysms who underwent early surgery within 72 hours were included in this study. Clinical outcome was assessed by Glasgow outcome scale[GOS] and compared with that of conventional pterional approach. Results : Twenty four patients were operated with conventional pterional approach and 11 with eyebrow approach within 72 hours after SAH. Seven multiple aneurysm patients harbor 15 aneurysms, Forty one aneurysms were treated with clippings. All 11 patients of eyebrow surgery group[ESG] were in H-H grade IV, 3 in Fisher grade III and 8 in Fisher grade IV. Among 24 patients of pterional approach group[PAG]. 20 were in H-H grade IV and 4 in H-H grade V, 3 were in Fisher grade III and 21 in Fisher grade IV. Overall favorable outcome was achieved in 41.7% and 54.5% in PAG and ESG, respectively. Favorable outcome of H-H grade IV in PAG showed 45.0%. Overall mortality rate was 14.3%. Conclusion : It is concluded that the clinical outcome of early and minimally invasive aneurysmal surgery using eyebrow incision in the selected poor grade aneurysm patients can be compatible with that of conventional pterional surgery.

It is important to concern about individual difference on every subject and every class. How can we know the individual difference? It is helpful for that to find out students' math learning style and learning type. In this paper, I conducted a survey to look for math learning style and math learning type of 4th, 5th and 6th grade students, and analyzed those data. The research findings are summarized as follows; First, 4th, 5th and 6th grade students prefer the visual learning style to the verbal style, and they have more wholistic tendency than analytical tendency in the domain of the cognitive learning style. Second, they prefer the authoritative and goal-oriented learning style to the practical and recreational learning style, and they have more interior-oriented than exterior-oriented in the domain of affective learning style. Third, the representative math learning type of 4th, 5th and 6th grade students is visual/holistic/authoritative and goal-oriented/interior-oriented. The math learning styles of students have a lot of influence on their learning, so that an appropriate teaching method for each student could arouse a maximum effect in the math study.
