  • Aldicarb와 carbofuran 두 가지 살선충제의 콩시스트 선충초기밀도 변화에 미치는 영향을 검정하기 위하여 각약제의 선충의 생존, 침입 및 생식에 대한 결과를 온실보험을 통하여 조사하였다. Ajdicarb은 선충의 생존(활력)에 미치는 영향이 컸으나 carbofuran은 선충의 활력에 결과가 없었다. 선충의 침입저지결과는 두 약제 모두 우수하였다. 약제처리에 의한 선충의 침입률은 대조구에 비해 aldicarb의 경우는 0.4%, carbofuran의 경우는 1.7%였다. 선충출입후 콩뿌리내의 선충생장에 미치는 영향, 즉 살선충제의 침투성결과는 두 약제 모두에서 유의성이 인정되었고, aldicarb이 carbofuran 보다 그 결과가 더 큰 것으로 나타났다. 선충에 오염된 토괴에 유묘이식시 살선충제를 처리한 결과, 각약제 처리구에서 cyst 형성율은 저 하되 었으나(p=0.05), 선충의 生存, 침입 및 생식에 미치는 살선충제 영향의 합계보다는 낮은 것으로 나타났다.

  • Biological and molecular characterization of a Korean isolate of Orthotospovirus chrysanthinecrocaulis (formerly known as chrysanthemum stem necrosis virus, CSNV) isolated from Chrysanthemum morifolium was determined using host range and sequence analysis in this study. Twenty-three species of indicator plants inoculated mechanically CSNV-Kr was investigated for determination of host range. CSNV-Kr induced various local and systemic symptoms in the inoculated plant species. CSNV-Kr could not infect three plant species and induced symptomless in systemic leaves in Nicotiana tabacum cultivars, though the plant samples reacted positively with the antiserum to CSNV by double-antibody sandwich-enzyme-linked immunosorbent assay. The complete genome sequence of CSNV-Kr was determined. The L RNA of CSNV-Kr consists of 8,959 nucleotides (nt) and encodes a putative RNA-dependent RNA polymerase. The M RNA of CSNV-Kr consists of 4,835 nt and encodes the movement protein (NSm) and the glycoprotein precursor (Gn/Gc protein). The S RNA of CNSV-Kr consists of 2,836 nt and encodes NSs protein and N protein. The Gn/Gc and N sequence of CSNV-Kr were compared with those of previously published CSNV isolates originating from different countries at nucleotide and amino acid levels. The Gn/GC sequence of CSNV-Kr shared 98.8-99.5% identity with CSNV isolated from other countries and the N sequence of CSNV-Kr shared 98.8-99.6% identity. No particular region of variability could be found in either grouping of viruses. All of the CSNV isolates did not show any relationship according to geographical origins and isolation hosts, suggesting no distinct segregation of the CSNV isolates.

  • 2011년 5월 '5 18 민주화운동 기록물'이 유네스코 세계기록유산으로 등재되었다. 이는 5 18이 시민운동으로서의 가치를 가진 역사임을 전 세계에 알리게 된 사례라 볼 수 있다. 하지만 이러한 국제적 인정에도 불구하고 5 18에 대한 그릇된 편견과 입장으로 이를 부정하는 기록물은 무시할 수 없을 만큼 도처에 널려 있다. 그들은 자신의 주장을 정당화하기 위해 기록물을 왜곡하면서까지 담론을 형성하고 있었다. 이에 따라 본 연구는 5 18 기록을 왜곡하는 담론의 문제점을 파악하고 이에 대응하기 위한 아키비스트의 기록관리 전략을 제시하는 것으로 주제를 두었다. 또한 본 연구는 아키비스트가 기존에 시행 중인 왜곡 대응에 보다 체계적인 전략을 제시함과 동시에, 아직 왜곡 담론에 휩쓸리지 않은 학생 등을 위주로 이들에게 진실된 기록을 토대로 한 담론을 제공하는 것을 목적으로 하고 있다. 이제 더 이상 아키비스트는 한정된 기록관에서의 정보를 제공하는 소극적 입장이 아닌, 적극적으로 5 18 담론에 대한 긍정적 인식을 심어줄 수 있는 입장이 되도록 노력해야 할 것이다. 따라서 추후 지속적으로 연구될 기록 왜곡 대응 전략 분석에 본 연구가 가치 있을 것이라 기대된다.

  • 전신 홍반 루푸스는 다양한 증상으로 발현되는 자가면역질환이다. 위장관 증상도 질환의 경과 중에 나타날 수 있으나, 장 가성 폐쇄로 처음 진단되는 경우는 소아에서 매우 드물다. 장 가성 폐쇄는 원발성 또는 속발성으로 장의 평활근이나 신경계에 이상이 있어 해부학적 원인 없이 장폐쇄의 증상과 징후가 나타나는 것이며, 장폐쇄로 인하여 수술을 하였다는 보고도 있다. 그러나 장 가성 폐쇄가 전신 홍반 루푸스에 속발한 경우 장간막 혈관의 폐쇄와 장괴사로 진행하기 전에 조기에 진단하고 치료하면 합병증을 예방하고 수술을 피할 수 있다. 저자들은 장 가성 폐쇄의 증상으로 내원한 13세 여아에서 전신 홍반 루푸스를 진단하여, 불필요한 수술을 피하고 조기에 치료한 증례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

  • Objective : Disaster causes psychological distress to a large number of people in a short period of time, by both direct and indirect exposure to traumatic events embedded in various realms of disaster experience. Optimal, well-planned treatment interventions should follow from the early acute period to recovery phase, extending up to several months later. In this context, there is an increasing need for systemic review to gain comprehensive insights for disaster interventions. These need to be added to public policy, and for the prevention and treatment of disaster-related psychopathology. Here, we review the published studies on psychological interventions for disaster-related posttraumatic stress disorder. Methods : Specific psychological interventions regarded as effective treatments for have been selected for this review, such as CBT (Cognitive-Behavior Therapy), Exposure Therapy, EMDR (Eye Movement Desensitization & Reprocessing), SIT (Stress Inoculation Therapy) and Psychoeducation. In addition, natural disasters, industrial disasters, and accidents involving aircraft and ships were also categorized as disasters, along with war and combat trauma. Results : Cognitive behavior therapy and exposure therapy had the strongest research support for effectiveness, and could be considered as the first-choice treatment for disaster-related PTSD. The second line of treatment is EMDR, although this treatment modality has the advantage of reaching certain treatment improvements in fewer sessions. However, the effects of SIT and psychoeducation to the survivors of disasters, remains unclear at this point. Additionally, we propose the possibilities of using virtual reality component and imagery rescripting as modified forms of traditional cognitive behavior therapy and exposure therapy. Conclusion : Cognitive behavior therapy and exposure therapy, deemed effective treatments for various trauma, are considered to be effective for survivors from disasters. However, the efficacy of other interventions has not yet been examined methodologically in well-designed studies, such as randomized controlled trials. In particular, future empirical studies are needed, since it is difficult to conclude that psychological interventions have similar effects on different types of disasters.

  • Chinae Rhizoma is dried crude roots and rhizomes obtained from Smilax china Linne which belongs to Smilax Genus of Liliaceae Familia, and it has been in wife use as a folk remedy for a long time. But very little systemic studies on its pharmacological actions have been made until now. Furthermore, the effective components except saponin of Chinae Rhizoma have been not known yet. It came to the attention of the authors that Chinae Rhizoma are used as antidiarrhetics in Chinese herb medicine, therefore they attempted to observe the effects of Chinae Rhizoma Alcoholic Extracts (Chinae Rhizoma Ethanol Extract=CREE, Chinae Rhizoma Methanol Extract=CRME) from Smilax china Linne on motility of the isolated rabbit duodenum in this experiment. The results of the study were as follow: 1. The movement of the isolated rabbit duodenum was slowed down and its tonus was relaxed in proportion to the concentration of Chinae Rhizoma Alcoholic Extracts (CREE & CRME). 2. With a concentration of CREE $10^{-4}g/ml$, the contractile effects of acetylcholine $10^{-6}g/ml$, pilocarpine $10^{-5}g/ml$ and physostigmine $10^{-5}g/ml$ were remarkably blocked in the movement of isolated rabbit duodenum. 3. The concentration of the isolated rabbit duodenum induced by barium chloride $10^{-4}g/ml$ was significantly inhibited by CREE $10^{-4}g/ml$. 4. With the administrations of histamine $10^{-5}g/ml$, serotonin $10^{-6}g/ml$ and prostaglandin $A_2\;10^{-6}g/ml$ respectively, contractions were observed in the rabbit duodenum. But, treatment of CREE $10^{-4}g/ml$ inhibited markedly the tonus and motility of the duodenum pretreated with the above drugs. 5. The effects of CREE and CRME were very much alike in this experiment. From the above results, it is concluded that the mechanism of action of Chinae Rhizoma on motility of isolated rabbit duodenum was partially due to cholinergic blocking effect.

  • Background: The superficial lymphatic system is divided into areas called lymphatic territories which are separated by watersheds. When the lymphatic system fails to remove its load either due to surgery, radiotherapy or some congenital malformation of it then the fluid and the proteins and wastes contained within it accumulates in that territory. Anastomotic connections exist across the watersheds and while they can work unaided manual lymph drainage (MLD) can significantly help drainage across them into unaffected lymphatic territories. The purpose of the study is to examine the effectiveness of a manual technique in moving fluids and softening hardened tissues using a tape measure and Patient-Specific Functional Scale. Methods: We examined the movement of fluids from the affected limbs of lymphedema patients who underwent a standardized 30-min treatment using the Dr. Vodder method of MLD. We chose a typical cross section of patients with secondary leg or secondary arm lymphedema. The lymphedema patient was also measured after the conclusion of treatment and underwent a follow-up control measurement, within 8 weeks. Both evaluation tools indicated a movement of fluid to different and unblocked lymphatic territories as well as a softening of tissues in some of the affected limbs. Results: MLD is an effective means of fluid clearance when it accumulates as a consequence of a failure of the lymphatic system. It seems likely that MLD has a systemic effect on the lymphatic system and that it can improve flow from otherwise normal tissues. Conclusions: It is hypothesized that a series of treatments would result in even more significant improvements.

  • Mutants of the monopartite geminivirus beet curly top virus (BCTV) have been screened for infectivity, systemic movement, replication and symptom development in Arabidopsis thaliana. As known by coding for coat protein, R1 mutant was not infectious and did not move systemically. R2, R3 and L2/L3 mutants produced milder symptoms compared to wild type BCTV but the infectivity was reduced by 40% to 60%. R2 ORF is thought to be involved in the regulation of ssDNA and dsDNA accumulation because only dsDNA was accumulated on R2-infected organs. Disruption of ORF L4 resulted in reduced infections, but the viral DNA was accumulated in infected organs from roots to shoot tips as much as wild type BCTV on Sei-O. In addition, 4 mutants did not produce callus-like tissues on infected organs, suggesting that L4 ORF may play a role in the induction of host cell divisions by virus infection. This result was supported by the patterns of mRNA expression and promoter analysis of the cell cycle marker gene, cycl, on Arabidopsis. cycl mRNA was accumulated on symptomatic organs by wild type BCTV infections but not by L4 mutant. We conclude that the BCTV L4 ORF is essential for symptom developments, specially callus-like formation on infected organs.

  • 스쿼시와 스트레치 원칙은 애니메이션 동작을 위한 필수적인 원칙으로 작용한다 이 원칙의 적용은 캐릭터에게 무게와 부피의 허상을 제공하며, 애니메이션 동작의 뻣뻣함과 딱딱함을 벗어나, 부드럽고 유연한 동작이 되게 하는 것을 가능하게 한다. 애니메이션에서 인물이나 사물의 동작표현을 실제 세계와 같이 표현하게 되면, 부자연스럽게 보인다. 스쿼시와 스트레치가 없는 어떤 동작이든 딱딱하고 흥미가 없고, 살아있지 않은 것으로 보일 것이다. 이것은 질량, 부피, 중력의 기본 법칙과 함께, 모든 사물의 움직임, 캐릭터의 동작, 대사, 얼굴표정 등에 모두 적용될 수 있다. 이 원칙이 없이는 어느 동작도 잘 표현되지 않을 것이다. 좋은 애니메이션 동작이 되려면, 이것은 2D 애니메이션에서 만이 아니라, 3D 애니메이션에서도 필이 적용되어야 한다. 따라서, 스쿼시와 스트레치 원칙의 체계적인 분석이 요구되어 진다.
