  • Objectives : This study was performed to understand smoking condition and to investigate the relations among knowledge regarding smoking and oral hygiene, awareness of anti-smoking policy, and self-esteem, to provide fundamental basis, developing programs for smoking prevention and anti-smoking. Methods : From September 7, 2010 to September 16, 2010, questionaire survey was conducted for 566 female university students studying dental hygienics at a local district in Jeollanam-do. Collected data was analyzed by Chi-square test, t-test, one way ANOVA, Scheffe multiple range test, Perason's correlation test, and stepwise multiple regression test. Results : 1. Smoking condition of study subjects on general characteristics showed 17.1%, where 14.0% of previous smoking history, and 68.9% of currently nonsmoker. 2. Analysis on the knowledge related to smoking and oral hygiene, awareness of anti-smoking policy, and self esteem on the general characteristics of study subjects have shown better awareness of anti-smoking policy in non-alcoholics. Significant difference was found in knowledge about smoking and awareness of anti-smoking policy according to current resident status, but no difference found in self-esteem. Higher academic grade was related to higher awareness of anti-smoking policy and better ics. aalcell. Better health, but no diffeoral hygiene were related to better awareness of anti-smoking policy, and bewhich were statistically significant. Favorable interpersonal self-estehip was related to better awareness of anti-smoking policy. 3. Analysis on knowledge regarding smoking related health and oral hygiene, awareness of anti-smoking policy, and self-esteem showed higher level of anti-smoking knowledge in non-smoking group(60.44) compared to currently smoking group or group with previous history of smoking, and better awareness of anti-smoking policy in non-smoking group(53.54) than other groups, which was statistically significant. 4. Correlation analysis among smoking related knowledge, awareness of anti-smoking policy, and self-esteem has found relatively high correlation between smoking related knowledge and awareness of anti-smoking policy, which was statistically significant(r=0.481, p<0.001). 5. Among factors influencing awareness of anti-smoking policy, higher level of smoking related knowledge and satisfaction to specialty was related to higher awareness of anti-smoking policy which was lower in current smoker than past smoker, and higher academic grade was related to higher awareness of anti-smoking policy. Conclusions : Following results emphasize the need to establish a novel curriculum by which effective programs for smoking prevention and education of anti-smoking specialist could be provided as well as promoting coaching anti-smoking activity.

  • A Gram-negative, strictly aerobic, non-motile, non-spore-forming, and rod-shaped bacterial strain designated FW-$6^T$ was isolated from a freshwater sample and its taxonomic position was investigated by using a polyphasic approach. Strain FW-$6^T$ grew optimally at $10-42^{\circ}C$ and at pH 7.0 on nutrient and R2A agar. Strain FW-$6^T$ displayed ${\beta}$-glucosidase activity that was responsible for its ability to transform ginsenoside $Rb_1$ (one of the dominant active components of ginseng) to Rd. On the basis of 16S rRNA gene sequence similarity, strain FW-$6^T$ was shown to belong to the family Sphingomonadaceae and was related to Novosphingobium aromaticivorans DSM $12444^T$ (98.1% sequence similarity) and N. subterraneum IFO $16086^T$ (98.0%). The G+C content of the genomic DNA was 64.4%. The major menaquinone was Q-10 and the major fatty acids were summed feature 7 (comprising $C_{18:1}{\omega}9c/{\omega}12t/{\omega}7c$), summed feature 4 (comprising $C_{16:1}{\omega}7c/iso-C_{15:0}2OH$), $C_{16:0}$, and $C_{14:0}$ 2OH. DNA and chemotaxonomic data supported the affiliation of strain FW-$6^T$ to the genus Novosphingobium. Strain FW-$6^T$ could be differentiated genotypically and phenotypically from the recognized species of the genus Novosphingobium. The isolate that has ginsenoside converting ability therefore represents a novel species, for which the name Novosphingobium ginsenosidimutans sp. nov. is proposed, with the type strain FW-$6^T$ (= KACC $16615^T$ = JCM $18202^T$).

  • A novel in situ-gelling and mucoadhesive acetaminophen liquid suppository was developed to improve the patient compliance of conventional solid suppository. In this study, acetaminophen liquid suppository, Likipe $n_{R}$, [aminophen/Poloxamer 407/Poloxamer 188/so4ium alginate (5/15/19/0.6%)] with relation temperature at 30-36 "C and suitable gel strength and bioadhesive force, dissolution pattern similar to conventional solid type suppository, Suspe $n_{R}$, was developed. Furthermore, the bioequivalence of two acetaminophen products was evaluated in 16 normal male volunteers (age 22-27 yr, body weight 56-72 kg) following sidle rectal administration. Test product was Likipe $n_{R}$ suppository (Dong-Wha Pharm. Corp., Korea)and reference product was Suspe $n_{R}$204-212 suppository (Hanmi Pharm. Corp., Korea). Both products contain 125 mg of acetaminophen. Four Suppositories of the test and the reference product were administered to the volunteers, respectively, by randomized two period cross-over study (2$\times$2 Latin square method). The determination of acetaminophen was accomplished using HPLC. Average drug concentrations at each sampling time and pharmacokinetic parameters calculated were not significantly different between two products (p>0.05); the area under the curve to last sampling time (24 hr) (AU $Co_{-2}$4h/) (30.14$\pm$8.64 vs 27.98$\pm$ 6.53 $\mu$g .h/ml), maximum plasma concentration ( $C_{max}$) (3.29$\pm$0.87 vs 3.60$\pm$0.66 $\mu$g/ml) and time to maximum plasma concentration ( $T_{max}$) (2.91 $\pm$0.55 vs 2.69$\pm$0.60 h). The differences of mean AUCo $_{24h}$, C-a. and T-between the two products (7.18%, 9.58% and 7.53%, respectively) were less than 20%. The power (1-7) and treatment difference ($\Delta$) for AU $Co_{24h}$, $C_{max}$ and $T_{max}$ were more than 0.8 and less than 0.2, respectively at $\alpha$=0.1. The confidence limits for AU $Co_{24h}$, $C_{max}$ and $T_{max}$ (-0.81 ~13.55%, -1.56~ 17.60 and -3.81 ~18.87%, respectively) were less than $\pm$ 20% at $\alpha$=0.1. These results suggest that the bioavailability of Likipe $n_{R}$ suppository is not significantly different from that of Suspe $n_{R}$ suppsitory. Therefore, two products are bio-equivalent based on the current results.results.lts.sults.results.lts.

  • Background: Neuroimaging can play a crucial role in discovering potential abnormalities to cause secondary headache. There has been a progress in the fields of headache diagnosis and neuroimaging in the past two decades. We sought to investigate neuroimaging findings according to headache disorders, age, sex, and imaging modalities in first-visit headache patients. Methods: We used data of consecutive first-visit headache patients from 9 university and 2 general referral hospitals. The International Classification of Headache Disorders, third edition, beta version was used in headache diagnosis. We finally enrolled 1,080 patients undertook neuroimaging in this study. Results: Among 1,080 patients (mean age: $47.7{\pm}14.3$, female: 60.8%), proportions of headache diagnosis were as follows: primary headaches, n=926 (85.7%); secondary headaches, n=110 (10.2%); and cranial neuropathies and other headaches, n=43 (4.1%). Of them, 591 patients (54.7%) received magnetic resonance imaging (MRI). Neuroimaging abnormalities were found in 232 patients (21.5%), and their proportions were higher in older age groups and male sex. Chronic cerebral ischemia was the most common finding (n=88, 8.1%), whereas 76 patients (7.0%) were found to have clinically significant abnormalities such as primary brain tumor, cancer metastasis, and headache-relevant cerebrovascular disease. Patients underwent MRI were four times more likely to have neuroimaging abnormalities than those underwent computed tomography (33.3% vs. 7.2%, p<0.001). Conclusions: In this study, the findings of neuroimaging differed according to headache disorders, age, sex, and imaging modalities. MRI can be a preferable neuroimaging modality to identify potential causes of headache.

  • The purpose of this study is to provide basic data for the establishment of future countermeasures by diagnosing the growth status and actual condition of undesignated old trees distributed in Hyeongok-myeon, Gyeongju, Gyeongsangbuk-do. The number of old trees surveyed was 2 weeks in Gajeong-ri, 2 weeks in Haguri, 3 weeks in Nae-Tae-ri, 1 week in Nawon-ri, 6 weeks in Oryu-ri, 3 weeks in Sangguri, and 2 weeks in Sohyeon-ri, The trees species composition was 6 trees Celtis sinensis Pers., 1 Diospyros lotus L. trees, 4 trees Salix chaenomeloides Kimura trees, 2 Styphnolobium japonicum L. trees, and 7 Zelkova serrata (Thunb.) Makino trees. Growth status is 7.1~22.0m in height, 14.6~25.1m in long axis, 10.2~19.2m in short axis, root diameter is 76.0~236.4cm, diamter at breast height is 67.0~220.0cm, soil acidity is pH4.9~7.0, soil The hardness was measured to be 4.0-27.0mm. The result grade of the scoring data of health information is represented by monitoring generally, monitoring critically, and absolute monitoring, and it was confirmed that out of the 20 trees population in Hyeongok-myeon, the general monitoring grade was 7 weeks, the major monitoring grade was 13 weeks, and there was no absolute monitoring grade. Accordingly, the number of old trees of the general surveillance level was maintained at the current level, and ecological surgical operations were introduced for the major surveillance level, but the case of village forests should be different, and sequential treatments were the old tree urgently needed. The level and bark of the target tree, the state of the crown, the root exposure, the presence of pests and pests, the vitality and the ground condition, the degree of pollution are normal, poor, or very poor, operation and protection management, soil improvement, removal of cover, and disinfection were urgently needed for the old trees with the surveyed data. In order to compensate for these matters, continuous monitoring and management measures for the old number should be sought.

  • 우리나라의 수질오염총량관리제도는 수계 내 모든 유역을 관리대상으로 동일 기준유량 조건에 동일한 대상물질로 관리하고 있지만, 본류는 지류의 영향을 받고 있으며 지류는 사람이 거주하는 지역 인근에 있어 본류 수질에 직접적인 영향을 미치고 있다. 이는 지류의 시급한 개선이 필요한 오염물질의 실질적인 관리가 어려워 이를 개선하기 위해 오염도가 높은 지류의 총량관리를 위한 지류총량제도의 추가 도입이 필요한 실정이다. 본 연구에서는 지류총량제 시행에 따른 효과를 예측하기 위해 팔당수계 유역을 소유역 단위로 분할하고 HSPF 모형을 적용하여 팔당수계 소유역 지류에서의 수질 변화 양상이 본류에 미치는 영향을 분석하였다. 연구대상지역은 팔당수계 중권역 유역(남한강 하류 유역, 경안천 유역, 북한강 하류 유역)으로 구분하고 유역 유출 및 수질 모델링은 지류하천을 포함하는 57개 소유역을 대상으로 수행하였다. 입력자료는 공간자료(표고, 경사, 토지이용, 토양도 등)와 기상자료(춘천, 양평, 이천, 수원관측소)는 2008년~2018년의 강수량, 최고기온, 최저기온, 평균풍속, 평균습도 등의 시단위 자료를 사용하였다. 모의결과, BOD는 남한강 하류유역의 주요 지천 유역인 복하천, 양화천, 청미천 및 흑천 유역에서 0.54~0.56mg/L의 범위로 주변 유역보다 높게 나타났으며, 경안천 유역은 경안천 유역의 중·하류 유역에서 2.63~4.22mg/L의 범위로 높게 나타났고, 북한강 유역은 조종천 하류 및 북한강 상류 유역에서 1.36~3.31mg/L의 범위로 주변 유역보다 높게 나타났다. T-P는 남한강 하류 유역은 주요 지천 유역인 복하천, 양화천, 청미천 유역에서 0.07~0.19mg/L의 범위로 주변 유역보다 높게 나타났고, 남한강 하류 유역의 중간 지점 유역인 한강(E1, E2, E4, E6)에서 높게 나타났다. 경안천 유역은 중·하류 유역의 좌안측 유역인 경안(A4, A3, B2, B1, F9)에서 0.1~0.14mg/L의 범위로 높게 나타났으며, 북한강 유역은 전체 유역에서 0.06mg/L 이하로 남한강 하류 및 경안천 유역보다 전반적으로 낮게 나타났다. 이와 같이 지류총량관리에 HSPF 모형의 적용은 가능하였으나 HSPF 모형을 이용한 소유역 단위의 유량 및 수질 예측을 위해서는 기존의 유량 및 수질 관측망을 소유역 단위로 좀 더 정밀하게 계획하는 것이 필요하다고 판단된다.

  • This study was performed in rats to find the minimum dose of melatonin that can effectively prevent the formation of postoperative intraperitoneal adhesions. Forty-two Sprague Dawley male rats were divided into six groups consisting of 7 rats, respectively. After celiotomy, five abrasions of $0.5{\times}1cm$ area were made on the antimesenteric serosal surface of the colon with a scalpel blade. The abdominal cavity was filled with 1 ml of solution containing 1 mg/kg(Mel 1), 3 mg/kg(Mel 3), 10 mg/kg(Mel 10), 30 mg/kg(Mel 30) and 5% ethanol solution(sham) through the catheter, using a sterile syringe before abdominal closure. Control group was given no adjuvant. The locations and values of adhesion were assessed through the second operation on the 14th day after the first operation. The adhesions were located on serosa to mesentery(54 of 210, 25.7%), serosa to serosa(44 of 210, 21%), serosa to omentum (12 of 210, 5.7%) and serosa to parietal peritoneum(0 of 210, 0%). The incidences of adhesion in Control, Sham, Mel 1, Mel 3, Mel 10 and Mel 30 were 68.6%, 91.4%, 57.1%, 60.1%, 17.1% and 20%, respectively. The values of adhesion separation in Mel 10 and Mel 30 group were lower than those in other groups. However, there was no significant(p<0.05) between Mel 10 and Mel 30 group. This study showed that 10 mg/kg of melatonin were effective in reducing the intraperitoneal adhesion.

  • This study was conducted from 2013 to 2014 in the middle region of Korea to compare the agronomic characteristics, forage production, and quality of kenaf, maize, and a sorghum ${\times}$ sudangrass hybrid. The three crops used in this study were kenaf "Hongma 300," maize "Kwangpyeongok," and the sorghum ${\times}$ sudangrass hybrid "Jumbo" (headless type). The sugar contents of the kenaf, maize, and sorghum ${\times}$ sudangrass hybrid were 5.4%, 4.4%, and 2.5%, respectively. The emergence rates and lodgings of the three crops were sound, as they were more than 80% and 1.5, respectively. The fresh yields of kenaf, maize, and the sorghum ${\times}$ sudangrass hybrid were 117,521 kg/ha, 73,336 kg/ha, and 133,334 kg/ha, respectively, and the dry matter (DM) yields were 28,598 kg/ha, 19,951 kg/ha and 20,083 kg/ha, respectively. The DM yield of kenaf was significantly the highest among the three crops (p<0.05). However, the total digestible nutrients (TDN) contents of the kenaf, corn, and sorghum ${\times}$ sudangrass hybrid were 43.3 %, 72.0 %, and 54.8 %, respectively, and the in vitro digestible dry matter (IVDDM) yields were 44.4%, 73.7%, and 59.6 %, respectively; therefore, the TDN yield of the corn was 13 % significantly higher than that of the kenaf (p<0.05). The TDN yields of the kenaf, corn, and sorghum ${\times}$ sudangrass hybrid were 12,472 kg/ha, 14,350 kg/ha, and 11,001 kg/ha, respectively. Among the three crops, the content of neutral detergent fiber (NDF) and acid detergent fiber (ADF) were highest in the kenaf. This study shows that the kenaf had a good forage productivity but a low forage quality.

  • Successful weaning is very important to provide adequate nutrients for normal growth and to induce a good diet habit. We conducted a survey on the knowledge and attitudes of women who live in Taegu toward weaning in infants, to figure out how much they know about weaning diet for the infants, which source they prefer to get the information about weaning diet, whether their knowledge affect their practice about weaning in infants, and the most effective way to educate them. A survey was conducted with the prepared questionnaire on women who responded at the residential area and market place, and those who visited Department of Pediatrics, Yeungnam University Hospital from July 25 to September 15, 1997. Statistical analysis was done with student t-test and ANOVA using SPSS program. Among total 303 responders, those who aged between 30 and 39 years were 37.2%. Scores for the six questions about weaning policy showed highest in the age group between 30 and 39 years. Higher score was recorded in the more educated group, in those who get informations about weaning diet from books, magazines and pediatricians. The majority of the responders had wrong concepts, such as feeding weaning diet using bottle(69.1%), feeding mixed with formula in the same bottle(64.5%), addition of salt(68.4%). Those who had higher educational level preferred books, magazines rather than neighbors or mother to get informations about weaning diet. Those who preferred books or magazines started weaning, stopped bottle feeding, and used spoon earlier, and their children had unbalanced diet habits less frequently. Home-made food was used most frequently, and commercial products were used less frequently. Those who were employed preferred home-made food rather than commercial products, it may be caused by the difference of the educational backgrounds from those of the unemployed. In conclusion, most responders ask neighbors and mother to get informations about weaning, and the incorrect knowledge from them could cause inadequate weaning practice and induce bad diet habit in their children. We have to find the reasons why they did not refer books or magazines frequently, and the way to resolve the problem.
