Long-term variations of PM_{10} and the characteristics of local meteorology related to its concentration changes were analyzed at 4 air quality sites (Ido-dong, Yeon-dong, Donghong-dong, and Gosan) in Jeju during two different periods, such as PI (2001-2006) and PII (2007-2013), over a 13-year period. Overall, the long-term trend of PM_{10} was very slightly downward during the whole study period, while the high PM_{10} concentrations in PII were observed more frequently than those in PI. The concentration variations of PM_{10} during the study period was clarified in correlation between PM_{10} and meteorological variables, e.g. the low (high) PM_{10} concentration with large (small) precipitation or high (low) radiation and in part high PM_{10} concentrations (especially, Donghong-dong and Gosan) with strong wind speed and the westerly/northwesterly winds. This was likely to be caused by the transport effect (from the polluted regions of China) rather than the contribution of local emission sources. The PM_{10} concentrations in “Asian dust” and “Haze” weather types were higher, whereas those in “Precipitation”, “Fog”, and “Thunder and Lighting” weather types were lower. The contribution of long-range transport to the observed PM_{10} levels in the urban center (Ido-dong, Yeon-dong, and Donghong-dong), if estimated by comparison to the data of the background site (Gosan), was found to explain about 80% (on average) of its input.

Background : The safety and effectiveness of influenza vaccine are well known in developed country. The influenza vaccination has been recommended as one of the tentative immunization schedule for indicated persons since 1997 in Korea. But there are still no available data about them, even though nearly 5 million doses of influenza vaccine were used in 1997-1998 season. So it is immediately needed to investigate the safety. efficacy and immunogenicity of influenza vaccine among Korean. Methods : We studied the clinical efficacy of influenza vaccine by monitoring Occurrence of influenza-like illness in influenza risk group(vaccination ; 300, non-vaccination; 215) from December in 1997 to March in 1998. We used the split quadrivalent influenza vaccine containing 15 microgram of hemagglutinin of A/Beijing/262/95(HlNl), A/Wuhan/359/95(H3N2), B/Mie/1/93 and B/Guangdong/5/94. Hemagglutination inhibition(HA1) antibody titers were determined before immunization and 1 months after vaccination And we evaluated adverse effect of influenza vaccination at 7 days after vaccination. Results : Influenza vaccination was associated with si@icant reductions in influenza-like spptoms(vaccination group; 28.35%, non-vaccination group, 35.88%, p=0.001). The preventive effect of influenza-like i3lne.s among influenza risk goup was 20.97%. And immunogenicity of influenza A and B exceeded all of the European licensure criteria for immunogenicity except postvaccination proportion of titers 240 of B/Guangdong/5/94 strain. And the adverse effects were mainly local injection site problem and no serious adverse effect was noted. Conclusion : Split influenza vaccine is safe, inmunogenic and eff'tive in influenza risk group in Korea.

메리골드(Tagetes patula L. 'Orange Boy')를 통해 오염지 식생복원과 동시에 양호한 식생경관 조성재료로서의 가능성을 알아보기 위해 본 실험을 수행하였다. 메리골드 'Orange Boy'에 있어서 Zn과 Cd 100+20㎎·L^-1 처리구에서는 GA_3 와 uniconazole은 생체량 및 Zn과 Cd의 축적에는 영향을 주지 않았다. 생장조절제 무처리구의 Zn과 Cd의 200+40㎎·L^-1 처리구에서 대조구의 20%로 건물량이 감소하였다. Zn과 Cd의 농도별 혼용처리에 따른 체내 무기성분 T-N, P, K, Ca, Mg함량은 뚜렷한 경향이 없었고, Zn의 축적은 뿌리와 잎에서 각각 1,227 및 903㎎·㎏^-1, Cd의 경우 줄기와 잎에서 각각 89.7 및 77.4㎎·kg^-1의 최대의 농도를 보였다. The use of plant-based systems to remediate contaminated soils has become an area of intense scientific study in recent years and it is apparent that plants which grow well in contaminated soils need to be identified and screened for use in phytoremediation technologies. This study was conducted to determine the effects of various combinations of Zn and Cd on growth and mineral concentrations of Tagetes patula L. 'Orange Boy'. With 100㎎·L^-1 Zn + 20㎎·L^-1 Cd, GA_3 and Uniconazole did not increase the plant biomass, and accumulation of Zn and Cd Total dry weight with 200㎎·L^-1 Zn and 40㎎·L^-1 Cd was 20% that of control. There was no significant to T-N, P, K, Ca, and Mg contents in leaf, stem, and root. The Zn contents of root and leaf were 1,227 and 903 ㎎·kg^-1, respectively. While the Cd was accumulated different site compared to Zn, the highest accumulation place were stem (74.4 ㎎·kg^-1) and leaf (89.7 ㎎·kg^-1).

The major purpose of this study was to analysis the appropriateness of generative learning model in primary science teaching. For this study, 41 children were selected from the 6th grade, and the model was applied to the samples for nine weeks(26hours) Various of teaching analysis tools and testing papers such as analysis framework for teaching, questionnaire for surveying conceptions, science inquiry ability and scientific interest etc were used. The conclusions of the study are as follows: Making a teaching plan for generative learning is required much time to the teachers, but it is useful in science teaching for using continuously this generative learning model is much better effective in applying for a long run. Because it's teaching strategy is almost discussion method it is vary interesting and understandable for students to take a science class. Also, generative learning model is vary effective in changing to conceptions, for example, such as surface change cased by earthquake and intensity of magnetic fields. This model is partially appropriateness for improving in science process skills and scientific attitude and interest to students. In a world, application for generative learning model is appropriateness in changing children's ideas, but it is requires much for a long per.

This study focuses on the measurement of airborne Volatile Organic Compounds (VOCs) in the Kumi electronic industrial complex during the time periods of August and September, 2002 and January and February, 2003. This study was based on the US-EPA method TO-14 while the VOCs were analyzed with GC/MSD. The toluene level revealed high concentration at all measurement sites. The areal rank of average concentrations of VOCs is as follows : industry l>industry2>urban>middle>residential. Concentrations of VOCs in Kumi electronic industrial ones were generally higher than at Yeochon and Ulsan industrial complexes. Dichloromethane and trichloroethylene, which are used as a cleaner in the process of electronic industries, were observed 4 to 8 times higher than those of other areas. Among the aromatic compounds, toluene showed the highest level, while the concentrations of dichloromethane and trichloroethylene were higher than those of other halogen compounds. In Kumi, toluene, trichloroethylene, and dichloromethane were confirmed as the major compounds of VOCs by this research.

The purpose of this study was to explore the effect of performance of living proprieties on family cohesion and Family satisfaction, centering on house wives in the lives of Korean housewives. The results of this study were as follows: 1. The practice of life propriety was shown to be relatively high in house wives. The variables that affected this level were as follows: perceptiveness to the importance of propriety, self-esteem, perceptiveness to resource reasonableness. 2. Family cohesion and family satisfaction revealed a relatively high level. The variables affecting the family cohesion were self-esteem, perceptiveness to resource reasonableness, age, perceptiveness to the importance of propriety. The variables affecting the family satisfaction were self-esteem, perceptiveness to resource reasonableness, perceptiveness to health, gender-role attitudes, income, perceptiveness to the standard of living, fare orientedness. 3. The degree of the practice of life propriety significantly affected family cohesion and family satisfaction. 4. On the family satisfaction, the result showed the practice of life propriety were lower figures compared to the family cohesion. The important variables affecting the Family satisfaction were self-esteem, perceptiveness to resource resaonableness, perceptiveness to the importance of propriety, degree of the practice of life propriety. In addition, it was found that the most significant variable that influenced family satisfaction was family cohesion. Future research is needed to expand its focus on the practice of life propriety in the area of family resource management. More concrete and specialized family life education programs should be developed for the benefit of building healthy families.

2000년도에 검정에서 역병에 살아남은 개체들로부터 채종하여 육성한 Capsicum chinense 31계통에 대하여 역병 저항성을 검정한 결과 고도의 저항성을 나타내는 것은 발견되지 않았다. 2001년도의 검정에서 역병에 살아남은 개체로부터 채종한 재래종 26계통에 대하여 다시 역병 저항성 검정을 실시한 결과 KC180, KC230, KC195, KC194에서 다수의 개체가 살아남아 저항성을 나타내었다. 그러나 KC180과 KC230은 각각 AC2258과 CM334와 혼종된 것으로 관찰되었다. KC195와 KC194는 재래종의 형질을 유지하고 있는 것으로 관찰되었다. CM334의 보존 증식과정에 자연교잡이 일어난 것으로 보여 이의 순도향상을 위하여 채종년도별로 시료를 꺼내어 역병저항성 검정을 실시한 결과 가장 오래된 1992년도 채종종자에서부터 약간의 이형주가 관찰도기 시작하여 1995년부터 2001년도까지 시간이 경과함에 따라 많이 변형되어 있는 것을 알 수 있었다. 1992년도 종자에서 이형주를 제거하고 원형의 개체로부터 자식종자를 대량으로 채종하였다. 함께 공시한 AC2258은 순수한 것으로 확인되었다. 1995년도 채종 CM334 종자에서는 비록 혼종은 되었으나 측지발생이 적은 개체들이 발견되어 이들을 개체 선발하여 역병에 저항성이며 측지발생이 적은 계통으로 육성하고 있다. A total of 31 c. chinense lines selected from 2000 screening were tested again for resistance to P. capsici but resistance was not found in the lines. A total of 26 selections from Korean land races tested 2001 spring were tested again for resistance to P. capsici. KC180, KC230, KC195 and KC194 showed moderate resistance to P. capsici. However, it was apparent on the basis of hortivultural characteristics that KC180 and KC230 had been naturally crossed with AC2258 and CM334, respectively. CM334 and AC2248 seed lots that were increased in different years were taken out and tested for resistance to improve their genetic purity because the resistant genetic resources have been showing some off-types in the population. Off-types began to be found in 1992 seed lots and the proportion and degree of the offs was increasing with time up to 2001. Plants true to the type in 1992 seed lots were selected and their inbred seeds were mass produced in a net cage in the greenhouse. AC2258 included in the experiment number of lateral branching at cotyledonary axil, although they were off from the original in the experiment together was uniform. In 1995 seed lost of CM334, plants with resistance to P. capsici and low or no number of lateral branching at cotyledonary axil, although they were off from the original CM334, were found and selection was applied to breed lines fixed in the characters.

이우용,정연권 대한응급의학회 1998 대한응급의학회지 Vol.9 No.2

Back ground : Intussuseception is one of the most common diseases requiring abdominal emergency care in early childhood. The delay in diagnosis increases morbidity and, in particular, reduces the success rate of the non-surgical method of reduction. In this report, the authors determined the clinical characteristics of pediatric patients with intussusception, and the factors involved in delayed diagnosis and the efficacy of doppler ultrasonography in diagnosis. Methods: The authors performed a retrospective study of 44 cases in 42 patients with intussusception who had visited the emergency room of SamSung medical center from January 1st to December 31, 1996. Results: The sex ratio was equal and 64.3% of the patients were under 1 year of age. The prevalent complaints were vomiting(36.4%) and abdominal pain(33.8%). Ultrasonography was used in 11 cases, 3 of them were performed because of obscure symptoms and the rest were due to diagnostic delay. The average time past from visit to diagnosis was 4hours and 20 minutes, and there were 4 diagnostic delays. Air enema reductions were unsuccessful in 11 cases(25%) and that was related to hospital-visit delays and long time past from symptom onset to diagnosis. There were no motalities. Conclusion: To reduce delays in diagnosis and unnecessary operations, the use of doppler ultrasonography is recommanded In suspicious cases. And to reduce the hospital-visit delays, related to the failure on non-surgical reduction, the education about this disease is necessary.
