Purpose: This study was carried out to suggest methods for improving school health promotion programs by investigating the daily activities and the performance level of environment management, the awareness of importance, and opinions on the revision of and knowledge about laws and regulations related to school health promotion programs. Method: The subjects of this study were 289 school nurses in Gyeongsangbuk-do. The survey used a questionnaire containing 90 questions developed by the present researcher. Data were collected from July 5 to July 21, 2006 and analyzed using SPSS 12.0 for Windows. Result: 1. Regular check-up and drinking water management got the highest score in performance level. Sexual health and drinking water management got the highest score in the awareness of importance. 2. School nurses were aware of laws and regulations related to their clients (0.93), and the revision opinion was high on the whole (3.58). 3. According to general characteristics, the more educated school nurse were (F=6.80, p=.001) and the fewer students their school had (F=4.66, p=.010), the higher their performance level in daily activities was. The shorter their career in their work was (F=4.86, p=.008), the fewer classes their school had (F=5.04, p=.007) and the fewer students their school had (F=3.83, p=.023), the higher their awareness of importance was. 4. There was not any difference in the performance level of environment management according to general characteristics. The awareness of importance was highest in school nurses with experience less then ten years (F=3.66, p=.027). 5. There was not any difference in knowledge about laws and regulations according to general characteristics. The revision opinion was high in school nurses at schools with less than 18 classrooms (F=6.04, p=.003) and less than 500 students (F=4.24, p=.015). Conclusion: When school nurses perform school health promotion programs actively and vigorously, the students can be healthy and national health promotion can be actualized fundamentally.

저농도로 희석된 HF 수용액(6 wt%)을 사용하여 $Al(OH)_3$의 표면을 F/Al의 몰비 0.15에서 처리하고, 처리 전후 표면특성을 관찰하였다. 반응계의 온도 및 pH 변화로부터 $Al(OH)_3$에 대한 HF의 표면반응은 HF와 접촉한 $Al(OH)_3$ 표면부에서 metastable한 ${\alpha}$형의 불화알루미늄$({\alpha}-AlF_3{\cdot}3H_2O)$이 안정한 ${\beta}$형의 불화알루미늄$({\beta}-AlF_3{\cdot}3H_2O)$으로 전이되는 과정으로 진행되며, 다량의 발열을 수반하면서 반응계의 온도상승을 유발하였다. 이러한 ${\beta}-AlF_3{\cdot}3H_2O$의 생성은 표면처리된 분말의 FT-IR 및 X-선 회절분석결과를 통해 확인되었다. ${\beta}-AlF_3{\cdot}3H_2O$의 morphology와 분포상태를 SEM을 통해 관찰한 결과 $Al(OH)_3$ 표면에 $1{\mu}m$ 이하의 미세분말 형태로 피복층을 형성하며 균일하게 분포된 것으로 확인되었다. HF로 처리된 시료의 표면 백색도는 미처리에 비해 약 6.6% 증가되었으며, 이는 $Al(OH)_3$보다 높은 백색도를 지닌 ${\beta}-AlF_3{\cdot}3H_2O$ 피복 효과 때문인 것으로 나타났다.

To figure out the geographical distribution of Gynaecotyla squatarolae and Microphallus koreana metacercariae in Korea, shore crabs of southwestern coastal areas were examined. Eight coastal areas in Inchon-si (A), Gyeonggi-do (B), Chungcheongnam-do (C, D, and E), Jeollabuk-do (F), and Jeollanam-do (G and H) were selected, and 2 kinds of crabs, Macrophthalmus dilatatus and/or Macrophthalmus japonicus, were caught. After transportation to the laboratory, 15 crabs per each group were grouped and ground in a mortar and pestle, and examined for microphallid metacercariae. In M. dilatatus, G. squatarolae metacercariae were recovered from 3 (C, E, and H) out of 6 regions, but M. koreana metacercariae were not recovered. In the case of M. japonicus, G. squatarolae metacercariae were recovered from 6 (B, D, E, F, G, and H) of 7 areas surveyed, and M. koreana matacercariae were detected from 5 regions (A, B, D, F, and H). These results indicate that the life cycle of G. squatarolae is maintained in the western coastal areas using M. dilatatus and M. japonicus as intermediate hosts, while that of M. koreana is maintained only using M. japonicus.

MPEG(Moving Picture Experts Group) 비디오 그룹은 사용자에게 움직임 시차(motion parallax)를 제공하면서 3D 공간 내에서 임의의 위치와 방향의 시점(view)을 렌더링(rendering) 가능하게 하는 6DoF(Degree of Freedom)의 몰입형 비디오 부호화 표준인 MIV(MPEG Immersive Video) 표준화를 진행하고 있다. MIV 표준화 과정에서 참조 SW 인 TMIV(Test Model for Immersive Video)도 함께 개발하고 있으며 점진적으로 부호화 성능을 개선하고 있다. TMIV 는 여러 뷰로 구성된 방대한 크기의 6DoF 비디오를 압축하기 위하여 입력되는 뷰 비디오들 간의 중복성을 제거하고 남은 영역들은 각각 개별적인 패치(patch)로 만든 후 아틀라스에 패킹(packing)하여 부호화되는 화소수를 줄인다. 이때 아틀라스 비디오에 패킹된 패치들의 위치 정보를 메타데이터로 압축 비트열과 함께 전송하게 되며, 본 논문에서는 이러한 패킹 정보를 보다 효율적으로 표현하기 위한 방법을 제안한다. 제안방법은 기존 TMIV10.0 에 비해 약 10%의 메타데이터를 감소시키고 종단간 BD-rate 성능을 0.1% 향상시킨다.

The Purpose of this study was to grasp the status of drug uses in college students, and to investigate the knowledge and attitude when they use it. We collected through questionnaires from Sep. 1 to Oct. 30 in 1999. The subjects were 490 college students in Seoul and northern of the Kyunggi-do. The data analysis was performed using SPSS (version 7.0) and ANOVA. The results of this study were as follows. 1. There was no correlation for all factors in the relationship between general characteristics of subjects and knowledge for drugs. On the contrary, in the relation of the general characteristics and attitude for drug of subjects, some factors are statistically significant e.g., department (F=3.049, p<.010), satisfaction for school life (F=6.167,p<.002), body shape(F=8.092, p<.000), and the relationship with ones parents (F=3.728, p<.005). 2. In the analysis of drug use status and knowledge, only in the factor of administration control was statistically significant(F=4.304, p<.014) and in the relation of attitude for drug uses, drug administration was statistically significant (F=4.521, p<.004). 3. In the mean scores for the drug knowledge analysis, the highest factor was 'A narcotic make deformed persons through poisoning of physical and mental' (M=4.14), the lowest factor was 'If catch the flu during the pregnancy, should be take drug as possible as quickly to reduce negative effect for fetal' (M=1.94). 4. In the analysis for drug attitude, the highest factor was 'A drug is alike a poison' (M=3.48), 'Should be keep the usage and dosage of drug' was the lowest (M=1.48). 5. From the investigation for status of drug use, it was revealed that the most subjects (73.6%) were purchase drugs after explain their symptoms to pharmacist. And they take drugs only when they felt painful in 43.1%. The most students (70.4%) were experienced control of drug administration. It was inquired that subjects were mainly obtained information about drugs from pharmacist and television (or radio) advertisement, 33.5% and 33.1%, respectively. In the examination for existence of long-term administrators in their family, 'none' and 'only parents' are 49.6% and 37.3%, respectively. When their parents have illness, the persons go to drugstore and hospital for heath-care, 47.8% and 44.3%, respectively. On the basis of results of this study, we suggest as follows. 1. This study was analyzed data from questionnaires for college students in a part of local areas, so we suggest that the next research should be perform for national-wide students as subjects to generalize the results. 2. It is need more intensive research methodologies such as interview and observation. 3. Additional research is required for knowledge and behaviors of drug uses that will how impact on ones health behavior.
