  • The control efficiency of the nematicides, aldicarb and carbofuran, in the population dynamics of the soybean cyst nematode(Heterodera glycines)was evaluated. Nematode viability, penetration and reproduction were examined in greenhouse experiments. Nematode viability(movement) was greatly reduced by aldicard, but mot by carbofuran. Penetration was inhibited by both chemicals. Percentages of Pentration relative to the untreated check 3 days after treatment were 0.4% and 1.7% for aldicarb and carbofuran, respectively. Systemic effect ot the nematicides were observed with both nematicides but effect was greater with aldicarb than with carbofuran. The total effect of the nematicides, applied ay the time of planting soybean in infested soil, appeared to be less than the sum of the contact and systemic effects on the initial population dynamics of H. glycines.

  • 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.

  • In May 2011, the 1980 Archives for the May 18th Democratic Uprising or the "5 18 Gwangju Democratization Movement" were registered as a UNESCO Memory of the World. This historic moment told the world that the 5 18 movement is a valuable and historical asset. However, despite the international recognition, archives that deny of such facts are still rampant because of misdirected standings and prejudices. These sources even develop discourses by distorting the archives to justify their claims. Accordingly, the study aimed to identify how these sources form ideologies surrounding the 5 18 movement discourses, which are characteristic of extreme social standings. It explored the possibility of the distortion of archives presented for each discourse and reconsidered the archivists' positions and roles to cope with such possibility. In addition, the author aims to suggest a more systemic strategy to advance the existing responses against the distortions, as well as provide discourses that are based on true and accurate archives mainly to students who have not yet been introduced to such distorted discourses. In the future, archivists shall try to develop positive awareness about the 5 18 discourses rather than maintain passive positions that provide information from limited archives. Through this, it is expected that this study will advance future analyses that would be effective against the distortion of archives.

  • Intestinal pseudo-obstruction (IPO) is a rare and poorly understood manifestation of systemic lupus erythematosus (SLE), especially in children. The characteristic clinical feature of IPO is obstruction without an identifiable obstructive lesion. The authors a 13-year-old girl whose first symptom of SLE was IPO. The patient presented with a 3-day history of nausea, bilious vomiting, abdominal distention, and no bowel movement. Simple abdominal radiographs revealed mild dilatation with partial air-fluid levels in the small intestine. Abdominal CT and methylcellulose small bowel studies showed massive ascites, engorgement of the small mesenteric vessels, pleural effusion, and diffuse bowel wall thickening of the gastric antrum, duodenum. and jejunum. The delayed passage of contrast for 15 days after the methylcellulose small bowel studies was suggestive of decreased bowel motility. Laboratory findings were positive for ANA, anti-double-stranded DNA, anti-Smith and lymphopenia. After 10-day treatment with high-dose corticosteroids, the symptoms improved. IPO associated with SLE should be considered in the differential diagnosis for patients presenting with symptoms of intestinal obstruction. Early recognition of IPO in SLE and appropriate therapy are important for prevention of complications and unnecessary surgery. This case raises awareness among pediatricians that although rare, IPO can be the presenting symptom of SLE in children.

  • 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.

  • Squash & Stretch principle is playing an essential principle for animation action. The application of this principle gives the illusion of weight and volume to an animation character, and makes it possible that an animation action be the smooth and soft by escaping from the stiffness and rigidity. If an action of human or object on animation is expressed like a real world, it seems to be unnatural. Any action without Squash & Stretch will look rigid, uninteresting and not alive. It can be applied to movement of all objects, characters' actions, dialogues and facial expressions with a basic rule of mass, volume and gravity. Any action will not be well expressed without this principle. To be a good animation action, it should be deeply applied in 3D animation, not only 2D animation. Thus, a systemic analysis of Squash & Stretch principle is required.
