The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

Blackleg disease, caused by Leptosphaeria maculans, greatly aff ects the production of cabbage ( Brassica oleracea ). However,defi nitive R-gene(s) are yet to be identifi ed in this crop. In contrast, a number of R-loci have been identifi ed in A- orB-genome crops. Identifi cation of few resistant cabbage genotypes indicates the presence of R-genes in this C-genome crop. High ancestral synteny between Brassica genomes suggests that the collinear regions of known A- or B-genome R-loci mayalso contain functional R-genes in the C-genome. Strong resistance was observed in the cotyledons of cabbage inbred lineSCNU-98 against two L. maculans isolates, 03–02 s and 00–100 s. We investigated the collinear region of the Brassica napusblackleg resistance locus LepR2’ in B. oleracea since both isolates of L. maculans contain corresponding avirulence genes. The locus was collinear to a 5.8 Mbp genomic segment of B. oleracea chromosome C09 containing 13 genes that have putativedisease resistance-related domains. High expression of genes Bo9g117290 and Bo9g111510 against isolate 00–100 s,and high expression of genes Bo9g126150 and Bo9g111490 against both isolates in the resistant-line SCNU-98 indicatetheir putative roles in blackleg resistance, which remained to be functionally verifi ed. This work enhances our understandingof R-gene-mediated resistance to blackleg in cabbage.

Eun Jeong Won,신주현,이유정,김문주,강승지,Sook In Jung,Soo Hyun Kim,Jong Hee Shin,채종일,신성식 대한기생충학ㆍ열대의학회 2019 The Korean Journal of Parasitology Vol.57 No.3

In recent years, the taeniasis has been rarely reported in the Republic of Korea (Korea). But in this study, we in- tend to report 4 taeniasis cases caused by Taenia saginata during a 5-month period (February to June 2018) at a unversity hospital in Gwangju, Korea. Worm samples (proglottids) discharged from all cases were identified by phenotypic and mo- lecular diagnostics. Mitochondrial cytochrome c oxidase subunit I sequences showed 99.4-99.9% identity with T. sagina- ta but, differed by 4% from T. asiatica and by 7% from T. multiceps, respectively. We found that tapeworms in 2 cases (Cases 2 and 3) yielded exactly the same sequences between them, which differed from those in Cases 1 and 4, sug- gesting intra-species variation in tapeworms. These taeniasis cases by T. saginata infection in this study, which occurred within a limited time period and region, suggest the possibility of a mini-outbreak. This study highlights the need for fur- ther epidemiological investigation of potentially overlooked cases of T. saginata infection in Korea.

In-vitro and in-vivo anti-inflammatory and antinociceptive effects of the methanol extract of the roots of Morinda officinalis

Kim, In-Tae,Park, Hee-Juhn,Nam, Jung-Hwan,Park, Young-Mi,Won, Jong-Heon,Choi, Jong-Won,Choe, Bong-Keun,Lee, Kyung-Tae EAST-WEST MEDICAL RESEARCH INSTITUTE KYUNG HEE UNI 2005 東西醫學硏究所 論文集 Vol.2005 No.-

The anti-inflammatory effects of the methanol extract of the roots of Morinda officinalis (MEMO) (Rubiaceae) were evaluated in-vitro and in-vivo. The effects of MEMO on lipopolysaccharide (LPS)induced responses in the murine macrophage cell line RAW 264.7 were examined. MEMO potently inhibited the production of nitric oxide (NO), prostaglandin E₂and tumour necrosis factor-α (TNF-α) in LPS-stimulated RAW 264.7 macrophages. Consistent with these results, the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) at the protein level, and of iNOS, COX-2 and TNF-α at the mRNA level, was also inhibited by MEMO in a concentration-dependent manner. Furthermore, MEMO inhibited the nuclear factor kappa B (NF-κB) activation induced by LPS, and this was associated with the prevention of degradation of the inhibitor κB (IκB), and subsequently with attenuated p65 protein in the nucleus. The anti-inflammatory effect of MEMO was examined in rats using the carrageenan-induced oedema model. The antinociceptive effects of MEMO were assessed in mice using the acetic acid-induced abdominal constriction test and the hot-plate test. MEMO (100, 200㎎㎏^(-1) per day, p.o.) exhibited anti-inflammatory and antinociceptive effects in these animal models. Taken together, the data demonstrate that MEMO has anti-inflammatory and antinociceptive activity, inhibiting iNOS, COX-2 and TNF-α expression by down-regulating NF-κB binding activity.

리조트 이미지 광고의 수사학적 표현 중 비유법이 소비자의 태도에 미치는 영향에 대한 연구

정종인 ( Jong In Jung ) 한국정보디자인학회 2011 정보디자인학연구 Vol.17 No.-

본 연구에서는 기업광고의 표현 방법 중 수사학적 표현이 소비자의 태도에 미치는 영향에 대한 연구로 시각적 측면에서의 효과 분석에 대한 연구이다. 어떤 수사적 표현이 광고효과가 있느냐는 선행과제에 광고효과와 소비자의 태도에 대한 부분을 리조트 광고에 국한하여 연구하고자 한다. 본 연구에서는 광고의 시각적 표현에 중점을 두고 기업이미지 광고에 가장 많이 쓰이는 수사법중 고등학교 분류표에 의한 비유법 중 직유법, 은유법, 열거법, 대유법, 대구법임을 문헌을 통해 확인하고, 이에 따라 임의의 기업을 선정하여 앞서 열거한 수사법을 적용한 광고를 제작하여 광고효과를 측정하고, 기업이미지 광고가 기업에 대한 소비자의 태도 변화에 대한 영향을 측정하였다. 측정결과는 실험자들을 대상으로 한 실험 결과에 광고의 효과를 크게 기억측면과 호의적인 반응 두 가지 측면으로 살펴보았다. 기억측면을 측정하기 위해 광고상기와 광고재인이라는 두 가지 변수를 사용하였고, 호의적인 반응을 측정하기 위해 광고태도를 사용하여 연구가 이루어졌다. 실증분석을 통해 얻어진 연구결과로 다음과 같은 결론을 얻을 수 있다. 기업이미지광고의 목표를 어떻게 설정하는가에 따라 광고 수사법을 다르게 사용할 필요가 있고, 기업이미지 광고에서는 직접적인 표현을 사용하는 것이 바람직하지 않다. 본 연구결과 직유법은 광고기억의 측면이나 호의적인 반응측면 모두에서 가장 낮은 평가를 얻고 있다. 따라서 기업이미지광고에서는 직유법과 같은 수사법이 바람직하지 않다고 할 수 있다. 끝으로, 기업의 상황에 따라 서로 다른 광고 수사법을 사용할 필요가 있다. 따라서 각각의 기업이 처한 상황에 따라 수사법을 달리하여 기업이미지광고를 하는 것이 바람직할 것이다 The current study experimentally investigated the effect of various rhetoric expressions used in corporate image ads. For the design of the experiment, a rhetoric classification model included in high school curriculum-simile, metaphor, enumeration, synecdoche, and parallelism-was adopted, and to measure the implications on both ad effectiveness and consumer attitude, this study selected one particular industry resort industry and created different ads according to the adopted rhetoric classification model. Ad effectiveness was measured in terms of two variables on memory: advertisement recall and advertisement recognition. Consumer attitude was measured in terms of favorable response scores given by the participants. The analyses of the data obtained from the experiment produced the following findings. The results show that the rhetorical style of simile received the lowest scores in both ad effectiveness (recall and recognition) and consumers` favorable attitudes. It indicates that direct comparison is not a desirable figurative style in corporate image advertisement. It issuggested, however, that a variety of rhetoric expressions can be considered and utilized for corporate image advertisement depending on the goals and objectives of such advertising as well as unique circumstances that each corporation is situated in.

<P><B>Background</B></P><P>For breast cancer patients who require electron boost energies between 6 and 9 MeV, an energy degraders (ED) in the 9 MeV beamline was specially designed and manufactured to increase the skin dose of 6 MeV and to reduce the penetration depth of 9 MeV beams.</P><P><B>Methods</B></P><P>We used Monte Carlo (MC) techniques as a guide in the design of ED for use with linear accelerators. In order to satisfy percent depth dose (PDD) characteristics and dose profile uniformity in water, the shape and thickness of Lucite® ED in the 9 MeV beamline was iteratively optimized and then manufactured. The ED geometry consists of a truncated cone attached on top of a plane plate, with total central thickness of 1.0 cm. The ED was placed on the lower most scraper of the electron applicator. The PDDs, profiles, and output factors were measured in water to validate the MC-based design.</P><P><B>Results</B></P><P>Skin doses with the EDs increased by 8–9 %, compared to those of the 9 MeV beam. The outputs with the EDs were 0.882 and 0.972 for 10 × 10 and 15 × 15 cm<SUP>2</SUP> cones, respectively, as compared to that of a conventional 9 MeV beam for a 10 × 10 cm<SUP>2</SUP> cone. The X-ray contamination remained less than 1.5 %. In-vivo measurements were also performed for three breast boost patients and showed close agreement with expected values.</P><P><B>Conclusions</B></P><P>The optimally designed ED in the 9 MeV beamline provides breast conserving patients with a new energy option of 7 MeV for boost of the shallow tumor bed.

혈액에서 연속 분리된 Staphylococcus epidermidis의 항균제 내성 및 Pulsed-Field Gel Electrophoresis 양상

최인옥,정숙인,신동현,박영규,신종희 대한감염학회 2004 감염과 화학요법 Vol.36 No.5

목적 : 혈액배양에서 Staphylococcus epidermidis가 분리될 경우 임상적 의의를 판정하기가 쉽지 않으나, 일반적으로 연속해서 분리된 균주가 동일한 유전형을 보이면 균혈증의 원인균일 가능성이 높다고 한다. 재료 및 방법 : 동일한 환자(12명)의 혈액에서 연속 분리된 S. epidermidis 각 2주씩을 대상으로 PFGE를 이용하여 유전형을 분석하여 동일 균주가 분리되는지 유무를 조사하고, 이를 항균제 내성양상 및 균주간의 분리일 간격과 비교하여 보았다. 결과 : 동일인에서 분리된 두 균주간의 PFGE 양상을 비교한 결과, 8명(66.6%)에서 분리된 균주는 동일한 PFGE 양상을 보였으나 4명(33.3%)에서는 서로 다른 양상을 보였다. PFGE 양상이 동일한 8명 중 7명에서는 항균제 내성양상도 동일하였으며, PFGE 양상이 서로 다른 4명에서는 항균제 내성양상도 서로 달랐다. 따라서 동일인에서 연속 분리된 균주에 대한 PFGE와 항균제 내성검사의 일치율은 91.7% (11/12)였다. PFGE 양상은 동일 환자에서 균이 분리된 시간 간격이 4일 이내 일 때 88.9%(8/9)에서 동일하였고, 분리일의 간격이 5일 이상일 때는 모두(3명)에서 서로 다른 PFGE 양상을 보였다. 결론 : 혈액에서 연속 분리된 S. epidermidis 균주의 PFGE 양상은 상당 수 환자에서 서로 달라, 동일 균종일지라도 오염의 가능성도 상당히 높음을 알 수 있었다. 연속 분리된 S. epidermidis 균주의 항균제 내성양상과 분리된 날짜 간격은 유전자형별 검사가 어려울 경우, 동일균주가 연속 분리되었는지 유무를 아는데 도움을 주리라 생각된다. Background : The significance of Staphylococcus epidermidis positive blood cultures is difficult to determine, but repeated isolation of the same organism with the same genotype is suggestive of true bacteremia. Materials and Methods : Two sequential isolates of S. epidermidis from blood cultures of the same twelve patients were genotyped by PFGE. The results were compared with those of antibiotyping and isolation time intervals between the two strains. Results : The two sequential strains from each patient had identical PFGE patterns in 66.6% (8 of 12) of the patients and two different types in 33.3% (4 of 12) of the patients. Antibiotypes of the two isolates from the same patient were different in all 4 patients whose isolates had different PFGE patterns, and they were the same in 7 of 8 patients whose isolates had identical PFGE patterns:the PFGE results were in agreement with the antibiotyping for 91.7% (11/12) of patients. The isolation time interval between the two strains was ≤4 days in 9 cases, 8 of which had identical PFGE patterns. In the 3 cases whose isolates had different PFGE patterns, the isolation time interval between the two strains was ≥5 days. Conclusion : These data showed that two consecutive isolates of S. epidermidis from blood cultures had different PFGE patterns in 33% of patients, suggesting a high prevalence of contamination. In the absence of genotyping measures, both antibiotype and isolation time interval can be alternative and useful tools for determining strain relatedness of sequential isolates of S. epidermidis from blood cultures.

Modeling of asymmetric degradation based on a?non-uniform electric field and temperature in amorphous In–Ga–Zn–O thin film transistors

Kim, Jong In,Jeong, Chan-Yong,Kwon, Hyuck-In,Jung, Keum Dong,Park, Mun Soo,Kim, Ki Hwan,Seo, Mi Seon,Lee, Jong-Ho Institute of Physics 2017 Semiconductor science and technology Vol.32 No.3

<P>We propose a new local degradation model based on a non-uniform increase in donor-like traps (DLTs) determined by distributions of an electric field and?measured device temperature in amorphous In–Ga–Zn–O (a-IGZO) thin film transistors (TFTs). A systematic investigation of the degradation model reveals that vertical field-dependent DLTs are essential for modeling of measured asymmetric electrical characteristics between the?source and drain after positive gate and drain bias stressing. An increased temperature due to self-heating is found to play a role in intensifying the asymmetric degradation. From the individual simulation of measured transfer curves at different stress times, the?model parameters and an asymmetry index as a function of stress time are extracted. It is expected that this novel methodology will?provide new insight into asymmetric degradation and?be utilized to predict the influence of electric field and heat on?degradation under various bias-stress conditions in a-IGZO TFTs.</P>

안종훈,방숙진,한남정,송왕영,황소영,이인수,박성주 대전대학교 이과대학 기초과학연구소 1997 自然科學 Vol.- No.-

산성강하물의 영향을 받는 대천공단지역과 영향을 받지 않는 청정지역인 대전 계족산 자연휴양림에서 자라는 밤나무(Castanea crenat)의 잎표면에서 서식하는 총세균수, 생존세균수, 종속영양세균수, 내산성세균수를 1996년 8월부터 1997년 8월까지 5회에 걸쳐 조사하였다. 공단지역 잎표면 평균 총세균수, 생존세균수 및 종속영양세균수는 각각 9.9×10^(5) cell/㎠, 1.6×10⁴cell/㎠, 7.1×10³cell/㎠,로서 청정지역에 비하여 각각 1.5배, 2배, 2.6배 정도로 관찰되었다. MPN법으로 측정한 pH 5.6애서의 잎표면 내산성세를수는 공단지역 3.3×10⁴, 청정지역 3.4×10⁴MON/㎠로 거의 같았고, pH 4.0에서의 내산성세균수는 공단지역애서 1.9×10^-(-1)MPN/㎠인 반면 청정지역에서는 전혀 검출되지 않았다. pH 3.0에서의 내산성 잎표면세균수는 공단지역과 청정지역의 잎권 어느 곳에서도 검출되지 않았다. 한편 계절별 잎표면세균수의 분포는 대체로 잎이 나기 시작하여 크기가 가장 작은 5월에 최대를, 그리고 낙엽이 지는 11월에 최소를 나타내었다. 이런 결과는 공단지역의 대기오염물질의 침적이 주변의 식물 잎표면 세균수를 감소시키지는 않으며, 특히 산성강하물의 영향으로 내산성세균수가 증가함을 보여주고 있다. Total, direct viable count, and acid-tolerant epiphytic bacterial population sizes were quantified on leaves of chestnut tree (Castanea crenata S. et Z.) near Taejon Industrial Estate affected by acid precipitation and deposition as well as in the clean natural forest area, Mt. Kyejok, in Taejon city from August 1996 to August 1997. Geometric mean numbers of total, direct viable count, and acid-tolerant epiphytic bacteria were 9.9×10^(5) cell/㎠, 1.6×10^(6)cell/㎠, and 7.1×10³cfu/㎠ respecfvely, being 1.5, 2, and 2.6 times those in the clean area. Acid-to-lerant epiphytic bfcterial numbers at pH 5.6 by MPN method were 3.3×10" in the industrial area, about the same as the number,3.4×104 MPNicni, of the clean area. Acid-tolerant bacterial number at pH 4.0 was 1.9×10^(-1)MPN/㎠ in the industrial area, whereas none was detected in the clean area. Acid-tolerant bacteria at pH 3.0 were not detected at all in the industrial area as well as in the clean area. Epiphytic bacterial population sizes were generally the greatest in May when leaves are emerged and grew but the lowest in November when defoliation occurs. These results showed that air pollutant deposition on leaves did not cause a deuease of epiphytic bacteria at least and acid deposition on leaves did cause an increase of acid-tolerant bacteria.
