The objective of this study was to investigate the effects of family meals on eating behavior, academic achievement, and quality of life among middle school students. A total of 302 participants were recruited from a middle school at Goyangsi. We asked participants about family meals, eating behavior, academic achievement, and quality of life, using structured questionnaires. Family meal questionnaires were classified according to frequency, rules, and awareness. The findings of this study were as follows. First, there were significant differences between rules(p<0.05) and awareness (p<0.05) of family meals and family type. Second, there were statistically significant differences between frequency and awareness of family meals and eating behavior, academic achievement, and quality of life. On the other hand, there was a significant difference between rules about family meals and eating behaviors and quality of life. Third, we found that factors of family meal were positively related to the eating behavior, academic achievement, and quality of life at the level of statistical significance. Finally, we found that participants with a higher frequency of family meals and more positive eating behavior were more likely to higher academic achievement and quality of life than those in lower frequency of family meals and less positive eating behavior among middle school students. The frequency of family meals has a strong effect on higher academic achievement and better quality of life. In conclusion, engagement in family meals was related to better eating behavior, academic achievement, and quality of life among middle school students. Our findings may warrant further studies to support the benefit of family meals in improving eating behavior, academic achievement, and quality of life among high school students as well as middle school students.

This study aims to make a "farmland use map" using high-resolution images and to analyze the land use change for about 8 years in Goyang, Namyangju, and Yongin cities. We have made a new numerical map named as a farmland use map using high-resolution images taken mostly in 2007 and digital topographical maps in Goyang, Namyangju, and Yongin cities near metropolitan areas to classify farmland use of paddy, upland, plastic film house, and orchard. We also made a land use map by overlaying the farmland use map and the land registration map of each city made in 2007, and compared the land use map made by RDA (Rural Development Administration) in 1999. Paddy areas decreased at a range of 3,000 to 5,000 ha during 8 years and were changed to residential areas in the cities. Upland and orchard areas also showed similar tendency and were changed to residential areas as well. On the other hand, the areas of the plastic film houses in the cities showed an increase or same in size. It is suggested that farmland use map can be broadly used as a base map for various survey projects including soil survey, statistics, and farmland information management.

The purpose of this study is to improve the previous groundwater contamination vulnerability assessment method, apply it to the study area, and select priority areas for groundwater management based on the quantitative analysis of groundwater contamination vulnerability. For this purpose, first, the previous 'potential contamination' based on groundwater contamination vulnerability assessment method was upgraded to the methodology considering 'adaptation capacity' which reduced contamination. Second, the weight of groundwater contamination vulnerability assessment factors was calculated based on the analytical hierarchy process(AHP) and the result of survey targeting groundwater experts. Third, Gyeonggi-do was selected as the study area and the improved methodology and weight were implemented with GIS and actual groundwater contamination vulnerability assessment was carried out. Fourth, the priority area for groundwater contamination management was selected based on the quantitative groundwater contamination vulnerability assessment diagram. The improved detailed groundwater contamination vulnerability assessment factors in this study were a total of 15 factors, and 15 factors were analyzed as new and improved weight with higher 'adaptation capacity' than the assessment factor corresponding to the previous 'potential contamination' in the weight calculation result using AHP. Also, the result of groundwater contamination vulnerability assessment in Gyeonggi Province using GIS showed that Goyang and Gwangmyeong which were adjacent to Seoul had a high groundwater contamination vulnerability and Pocheon and Yangpyeong County had a relatively low groundwater contamination vulnerability. In this study, the previous groundwater contamination vulnerability assessment was improved and applied to study areas actually. The result of this study can be utilized both directly and indirectly for the groundwater management master plan at national and local government level in the future.

MOCVD법으로 TiN 표면에 Ru을 증착함에 있어서 Ru의 핵생성을 고양시키기 위한 ECR plasma 전처리 세정이 필요하다. 본 연구에서는 Ru 증착시 ECR $H_2O$$_2$, AE Plasma 전처리 세정 효과를 SEM, AES, XRD로 분석하였다. Ru의 핵생성은 ECR H$_2$, Ar Plasma의 노출시간이 증가할수록 향상된 반면, ECR $O_2$ plasma의 경우 노출시간이 증가할수록 핵생성 효과는 감소하였다. H$_2$ plasma 내의 H$_2$ion은 Ti와 NH$_3$를 형성하기 위해서 TiN과 반응하여 TiN을 Ti로 개질 시켰으며, Ar plasma 전처리 세정하는 동안 Ar plasma 내의 Ar ion은 TiN 또는 TiON 표면의 질소와 산소원자를 제거하는 효과를 나타내었다. 그 결과 TiN 표면상에서도 Ru의 핵생성이 쉽게 이루어졌으며 H$_2$, Ar ECR Plasma 전처리 세정에서 RU 핵생성이 향상되는 결과를 얻었다. 세 종류의 plasma중에서 Ar ECR plasma로 전처리 세정한 경우에 가장 높은 Ru 핵생성 밀도를 얻을 수 있었다.

The kidney, heart and lung were examined of cats fallen sick lower urinary tract disease(LUTD). There cases typically clinical findings were urinary retention, hematuria, dehydration, cytoplegia and uremia. It is believed that these histopathological and clinical findings resulted from the struvite crystal thrombus in ureter. But we have many factors of an unsolved problem on LUTD. Accordingly, this LUTD demands to process of pathological diposition.

2001년 9월 11일 미국에 대한 항공기 데러 이후 해상화물운송선박 및 항만시설에 대한 해상 테레에 대비하고자 IMO에서 "국제선박 및 항만시설보안 코드(ISPS Code)"를 제정 및 채택하여 2004년1월 1일부터 발효 중이다. 이와 관련하여 선박에서 이를 적용하기 위하여 해운선사에서는 많은 노력을 경주하였으며 보안시스템을 효과적으로 운영하는가에 대한 검증은 선박보안심사를 통하여 이루어지고 있다. 또한 보안시스템을 운영하고자 할 경우에는 회사보안책임자, 선박보안책임자 및 해상종사자에 대한 효과적인 사전교육이 반드시 필요한 실정이다. 따라서 향후 선박보안심사는 ISM 심사와의 차이를 고려하여 시스템의 이해 및 운영, 보안설비 정비, 보안사건 발생시 비상대응 및 시스템활동기록의 검증에 집중하여야 하며 ISM 심사와의 통합형태가 되어야 할 것이다. 또한 선박보안교육의 경우에는 교육기관을 통한 보안교육에만 의존할 것이 아니라 승선 전 및 승선 후 교육을 통하여 보안의식을 고양시키어야 한다.

Effect of a $Na^+$ gradient on $Ca^{2+}$ uptake was studied in isolated sarcolemmal vesicles of cat ileal longitudinal muscle. $Ca^{2+}$ uptake was markedly stimulated in the presence of an outwardly directed $Na^+$ gradient. External $Na^+$, monensin and A23187 abolished the $Na^+-dependent$ $Ca^{2+}$ uptake. Monovalent cations such as $K^+$, $Li^+$, $Rb^+$, $Cs^+$ and choline could not substitute for $Na^+$ in enhancement of $Ca^{2+}$ uptake. Divalent cations such as $Ba^{2+}$, $Sr^{2+}$, $Mn^{2+}$ and $Cd^{2+}$ but not $Mg^{2+}$ inhibited the $Na^+-dependent$ $Ca^{2+}$ uptake. Increase in external pH in the range of 6.0 to 8.0 stimulated the $Na^+-dependent$ $Ca^{2+}$ uptake. Amiloride inhibited the $Na^+-dependent$ $Ca^{2+}$ uptake at concentrations above 0.5 mM, whereas diltiazem or vanadate did not. The apparent Km of the $Na^+-dependent$ $Ca^{2+}$ uptake for $Ca^{2+}$ was 18.2 ${\mu}M$ and apparent Vmax was 689.7 pmole/mg protein/5 sec. Kinetic analysis of the $Na^+-dependent$ $Ca^{2+}$ uptake showed a noncompetitive interaction between internal $Na^+$ and external $Ca^{2+}$. The dependence of $Ca^{2+}$ uptake on internal $Na^+$ showed sigmoidal kinetics and Hill coefficient for internal $Na^+$ was 2.52. Inside positive membrane potential generated by imposing an inwardly directed $K^+$ gradient and valinomycin significantly stimulated the $Na^+-dependent$ $Ca^{2+}$ uptake. These results indicate that a $Na^+-Ca^{2+}$ exchange system exists in the sarcolemmal membranes isolated from cat ileal longitudinal muscle and it might operate as an electrogenic process.

Based on the results of previous studies, endoscopic biopsy sample's quality has a major impact on its adequacy for histopathology, and that the nature of the biopsy forceps can influence the specimen quality. The present study compared the effects of three different types of endoscopic biopsy forceps and two different operators on sample quality and adequacy for histopathology in three healthy cats. Every biopsy was performed between the major papilla and caudal duodenal flexure, and each operator performed five biopsies with each type of forceps on each cat, for a total of 90 biopsies. One pathologist evaluated the quality and adequacy of the obtained samples. Biopsies performed with large-cup forceps provided heavier and longer samples than the standard round forceps. With the same size forceps, the presence of alligator teeth had no effect on sample quality or adequacy for histopathological examination and assessment. Based on the results of the present study, although the standard round forceps could be used to obtain adequate samples for histopathology, large-cup forceps such as the standard oval and alligator jaw type have the advantage of obtaining high quality endoscopic samples.
