대서양 청어는 바닷가재 어업에 있어 주요 미끼로서 사용되어지고 있고 해양 생태계내에서 다른 어류들의 먹이로서 중요한 위치를 차지하고 있다. 그러나 해양생태계의 환경적인 요소, 즉 해수면 온도, 플랑크톤량, 서식지 해저퇴적물 상태에 따라 자원이 민감하게 영향을 받는다. 특히 미성어의 단계에서는 낮은 해수 온도에 대해 영향을 받기가 쉽다. 이 연구에서는 인공위성을 이용하여 측정된 해수면 온도와 2년생 가입자원의 상관관계를 분석하였다. 해수면 온도의 측정지역은 대서양 청어의 산란지역으로 한정하였다. 연구 결과 상관계수는 0.69로 나타났고 이는 어업자원의 변동성을 설명함에 있어 환경적인 요인이 중요하게 고려되어야 한다는 것을 의미한다.

Objective : The purpose of this study is to provide reference to functional level of sensory integration of in the low-grads school age, based on the Clinical Observation of Motor and Postural Skills (COMPS) and to examine correlation between the function of sensory integration and academic achievement. Method : Two schools ("J" and "S") have been selected indiscriminately among 56 elementary schools located in Gimhae-si, GyeongNam and then one class from each school was voluntarily chosen among all second-grade classes of the schools. The total number of students in those two classes was 69 (34 boys and 35 girls). Subjects had no developmental problem and no history of referral regarding neurological conditions. Three skilled researchers administrated the COMPS together, and each researcher executed two sub-items of the COMPS. As result of the academic achievement, score data of midterm- and final-exam in the spring semester were collected. The scores of 'Korean language' and 'Math', common examination subjects in both schools, were utilized for data analysis in this study. Results : Statically, there was no significant correlation between the COMPS Weighted Scores and any academic achievements. In a dispersion graphic analysis, however, the total achievement showed significant negative-correlation with the area of 'Rapid Forearm Rotation' and significant positive-correlation with the area of 'Supine Flexion'. In terms of the Math achievement, there are significant negative-correlation with rapid forearm rotation and asymmetrical tonic neck reflex, and significant positive-correlation with the area of 'Supine Flexion'. Students with higher score of the Korean language showed a tendency to get higher Weighted Score and Minus Adjustment Score, and those with lower score of the Math showed a tendency to get higher COMPS scores in all area except the area of 'Supine Flexion'. There was a statically significant difference in the COMPS scores depend on the age among general characteristics. As student older, all COMPS scores, except those in the area of 'Slow Motion' and 'Supine Flexion, were higher. Conclusions : There is somehow reliable correlation between sensory integration function and academic achievement although no statistical significance found in this study. The information from this study may contribute to initiate developing a normative-reference to screen earlier and more alertly sensory integration dysfunctions for school-age children. Further study is recommended trying to find out more reliable matter regarding low grade- schooler's academic achievement.

This study analyzes the correlation between noise and the size of urban forests. Under the assumption that the main cause of the noise m the city is the population density, the size of urban forests per capita and the ratio of urban forests with respect to the size of urban per 100 thousand persons are used for the calculation of correlations with noise. The results of the calculations of Pearson's and Spearman's correlation coefficients indicate that the increase in the size of urban forests has a significant effects in reducing the day-time as well as night-time noise for most regions in the cities. The size of urban forests within public parks has a significantly negative correlation with the noise. However, calculated correlation coefficients imply the increase in the size of total urban forests is more effective in reducing the noise than the increase in the urban forests in public parks.

Sorghum×sudangrass hybrid (Sorghum bicolor (L.) Moench, SSH) is one of the most important summer forage crop and it is widely used for silage in Korea. Agriculture is highly dependent on the climate condition and experiencing significant loss of productivity due to climate change. This study was conducted to investigate the correlation analysis between productivity of forage SSH and climatic factors in Central Northern region of South Korea for 3 years (2017 to 2019). Plant height and dry matter yield of SSH were significantly higher in Gyeonggi-do than Ganwon-do. The productivity of SSH is more closely related with temperature than other climatic factors. Maximum temperature and Growing degree days in May and June showed a positive correlation. However, correlation between production of SSH and precipitation was not clear in this study, but rainy days showed a negative correlation (0.42). In conclusion, temperature is most important climatic factor to the maintenance of plant yield.

The aim of this study was to investigate effect of nutrition education methodology on consumption of processed food and personality of middle school students aged 14 to 16 years who live in Busan. We categorized questionnaire based on students' consumption of processed food and personality characteristics. Based on the above, we determined serum mineral level to validate the correlation between personal characteristics and quantifiable serum mineral level. Following adoption of a proper nutrient education methodology, we found that consumption of processed foods such as meat and meat products, frozen food, noodles, bread and snacks, and drink was significantly reduced. In addition, there were distinct changes in personality characteristics such as stability, governmentality, sociality, and responsibility that became markedly increased, whereas impulsiveness decreased. We found that these distinct nutrition- education-based changes were statistically significant, when compared before and after providing proper nutrition education. We interpret these results as group with low stability showed a high consumption of meat and meat products, noodles, bread and snacks, and drink, whereas group with high stability showed a high consumption of milk and dairy products. Similarly, we also found that group with low impulsiveness showed a high consumption of canned foods, whereas group with high impulsiveness showed a high consumption of meat and meat products, frozen food, noodles, bread and snacks. Our results indicated that serum Na after nutrition education decreased, whereas other minerals including Ca, Fe, Zn, Mg and K increased, when compared with before nutrition education procedure. This study suggests that nutrition education methodology and establishment of proper dietary educational programs keeping in view balanced dietary habits for middle school students would not only appear to make them get along with healthy dietary habits, but also change their personality characteristics.

The phenolic substances contents of 45 plant foods in Korean diet were determined by different methods. Total phenolics contents by Folin-Denis method were $0.1{\sim}5.8%$ (dry matter basis), in which persimmon leaf, chestnut's inner skin, Chinese quince, walnut, sunflower seed and arrowroot exhibited the higher levels above 2%. Condensed tannin contents by vanillin method were $0{\sim}48%$, in which Chinese quince and chestnut's inner layer gave very high levels. Protein-precipitable phenolic substances ranged from 0.4% to 2.2%, in which chestnut's inner layer, walnut and Chinese quince had the highest content. The ability of phenolics to form precipitate was higher with pepsin and albumin than with trypsin. Among different phenolics content, total phenlolics correlated significantly with protein-precipitable phenolics (r=0.65) and condensed tannin (r=0.56). Chinese quince, chestnut's inner skin and sorghum showed a relatively lower degree of polymerization, as expressed by vanillin/FolinDenis ratio. Processed foods from buckwheat, acorn, mugwort and arrowroot showed a lower content of phenolic substances, suggesting a negligible adverse effect on the bioavailability of food proteins, if any.

In this study, the physicochemical characteristics of imported whole sesame oil (WS; WS1, WS2), imported sesame powder oil (SP; SP1, SP2), sesame oil mixed with imported whole sesame and sesame powder (WSP; WSP1, WSP2) were analyzed and their quality characteristics were compared according to the imported raw material type. $L^*$ and $b^*$ values of WS1 were the lowest and the browning index was significantly high. WS2 showed contrasting results. The redness of sesame oil was high due to its high acid value. The correlation value showed a low acid value as the content of saturated fatty acid was high. SP showed low values for antioxidant property and overall preference. The overall preference score of sensory evaluation showed the highest positive correlation with the score, suggesting that SP lacked the unique fragrance. Therefore, SP lacked the specific aroma and antioxidant property.

Chlorophyll fluorescence of needles of Korean fir (Abies koreana) plants and environmental factors of their natural habitat were investigated in order to obtain the information for environmental adaptation and conservation of Korean fir plants. The photochemical efficiency of photosystem II, Fv/Fm, of Korean fir needles was significantly low (0.19-0.36) in the winter, whereas it was high (0.8-0.86) in the summer. The Fv/Fm value of the winter was slightly higher at mid-day than at dawn, suggesting that mid-day environmental conditions of the winter were favorable on needles of Korean fir plants. In contrast, the mid-day Fv/Fm value of the summer maintained high (around 0.8). It indicates that mid-day environmental conditions of the summer did not induce photodamage, although it caused a slight decrease in the Fv/Fm values. The non-photochemical fluorescence quenching (NPQ) of Korean fir needles was very low (0-0.01) all through the day in the winter. However, it was high (0.76) at mid-day in the summer. These results suggest that Korean fir plants have a system for the protection of PS II from mid-day environmental stresses of the summer. In the winter, the Fv/Fm values were positively correlated with temperature, light intensity and relative humidity, although NPQ values showed no correlation with any of them. In the summer, the Fv/Fm values were positively correlated with relative humidity but negatively correlated with temperature and light intensity. These results indicate that increase of tempera-ture, light intensity and relative humidity lead to promotion of the photochemical efficiency in the winter and high temperature and light intensity may cause photoinhibition in the summer.
