The purpose of this study was to examine the moderating effect of perceived parental empathy in the relationship between adolescent depression and eat problem. For this purpose, we conducted a hierarchical regression analysis for 246 middle and high school boys in the K region. As a result, the relationship between eating problem and depression was controlled by parental sympathy. As a result of analyzing the moderating effects of sub- factors of parental sympathy, in the case of the father, awareness of emotion, cold emotional reaction, and excessive emotional reaction showed moderating effects. And in mothers, awareness of emotion, perspective taking, cold emotional reaction, and excessive emotional reaction moderated the relationship between eating problem and depression. It is significant that this study confirmed that the empathy of parents perceived by adolescents is a control variable to mitigate the adverse effects of depression on eating problems.

Objectives The purpose of this study was to observe clinical reactions (itching, pain, etc.) after Essential Bee Venom (EBV) treatment. Methods This study was conducted 64 patients who had been injected with EBV in Korean Medicine Hospital of Woosuk University and Haeundae Ja-Seng Hospital of Korean Medicine from October 5, 2015 to February 20, 2016. We checked clinical reactions of treatment region. Results 8 patients (12.5%) complained of localized itching and 4 patients (6.3%) complained of localized pain after EBV injection. In itching reaction of patients, 2 patients (15.4%) occurred itching in head and neck, 4 patients (12.9%) occurred in lumbar and back. In pain reaction of patients, 2 patients (6.5%) occurred pain in lumbar and back, 1 patient (11.1%) occurred pain in upper limb. All clinical reactions were happened within 7 treatment times. Conclusions This study suggested EBV treatment can cause clinical reaction like itching and pain. Clinical reactions were more common in inpatients than outpatient, and all reactions were happened within 7 treatment times. Doctors should recognize physical reaction caused by EBV and explain to patient. Further studies are needed to more improved treatment.

The trend of poisoning of reforming catalyst along with the position of anodic catalyst bed was studied. Keeping the conditions that steam to carbon ratio was 2.5, operating voltage was 0.75 V, current density was $140mA/cm^2$, the unit cell was operated during 24 hrs at a steady state. And then the cell was stopped, the catalysts packed in the position of inlet, middle and outlet were sampled individually and then the amount of carbon, Li and K poisoned were analysed. After 100 hrs operated, the catalysts at the same positions were analysed at the same manner. The result of this experiment was as followings. After 24 hrs operated, the poisoning amounts of Li and K in the catalyst were 0.27 wt% at inlet, 0.23 wt% at middle and the highest value 1.59 wt% at outlet. After 100 hrs, the amount of poisoning is the highest in the catalyst packed at the inlet of unit cell. The performance simulation of unit cell explained these trends of poisoning catalysts. The simulation told that the catalyst in the region of the inlet of unit cell treated the 90% of initial methane flow rate and the highest electrochemical reaction happened in this region. So the catalysts of this region were the most poisoned with carbon, Li and K and also the rate of poisoning is faster than that of the catalyst at other regions. The temperature at the region of outlet of unit cell was $30^{\circ}C$ higher than that of other regions, so more Li, and K vaporized than at other regions and little reforming reaction at this region made the catalysts poisoning rate low.

The increasing economic losses associated with growth retardation caused by Enterocytozoon hepatopenaei (EHP), a microsporidian parasite infecting penaeid shrimp, require effective monitoring. The internal transcribed spacer (ITS)-1 region, the non-coding region of ribosomal clusters between 18S and 5.8S rRNA genes, is widely used in phylogenetic studies due to its high variability. In this study, the ITS-1 region sequence (~600-bp) of EHP was first identified, and primers for a polymerase chain reaction (PCR) assay targeting that sequence were designed. A newly developed nested-PCR method successfully detected the EHP in various shrimp (Penaeus vannamei and P. monodon) and related samples, including water and feces collected from Indonesia, Thailand, South Korea, India, and Malaysia. The primers did not cross-react with other hosts and pathogens, and this PCR assay is more sensitive than existing PCR detection methods targeting the small subunit ribosomal RNA (SSU rRNA) and spore wall protein (SWP) genes. Phylogenetic analysis based on the ITS-1 sequences indicated that the Indonesian strain was distinct (86.2% nucleotide sequence identity) from other strains collected from Thailand and South Korea, and also showed the internal diversity among Thailand (N = 7, divided into four branches) and South Korean (N = 5, divided into two branches) samples. The results revealed the ability of the ITS-1 region to determine the genetic diversity of EHP from different geographical origins.

The unique gene encoding thioredoxin reductase (TrxR) was previously cloned and characterized from the fission yeast Schizosaccharomyces pombe, and its expression was induced by oxidative stress. To elucidate tbe regulatory mechanism of the S. pombe TrxR gene, three fusion plasmids were generated using polymerase chain reaction: pYUTR20, pYUTR30, and pYUTR40. Plasmid pYUTR20 has an upstream region of 891 base pairs, pYUTR30 has 499 in this region, and pYUTR40 has an 186 bp upstream region. Negatively acting sequence is located between $-1,526\;\~\;-891bp$ upstream of the gene. The upstream sequence, responsible for the induction of TrxR by menadione (MD), is situated on the $-499\;\~\;-186bp$ region, which is also required for TrxR induction by mercuric chloride. The same region also appeared to be required for Pap1-mediated transcriptional regulation of the TrxR gene, which contains the two plausible Papl binding sites, TTACGAAT and TTACGCGA. Consistently, basal and inducible expression of the TrxR gene was markedly lower in the Pap1-negative TP108-3C cells than in wild-type yeast cells. In summary, up-regulation of the S. pombe TrxR gene is mediated by Pap1 via the transcriptional motif(s) located on the $-499\;\~\;-186bp$ region.

There are four kinds of diagnosis methods in oriental medicine, and viewing diagnosis(望診) is the most important method among them. There are two ways in viewing diagnosis. These are viewing shape(觀形) and inspecting color(察色). Viewing shape diagnosis includes observation on geometric curve that is made by prominence of bones or lump of flesh, and examination on symmetric disparity and balance of vertical length among three vertical section of face. Inspecting color is literally inspecting several specified region of face. By Viewing shape, we can learn about characteristic physical mechanism of individuals, and basic disposition of reaction from inside and outside infinite stimulations. On the other hand, by inspecting color, we can estimate the very present pathologic and physiologic status of the patient. the estimation is based on principle that inside body changes reveal some reflections on facial skin surface. When you diagnosis patients with inspecting color method, It is important to distinguish color delicately, and to know where to see and what to know from it. The most important and frequently mentioned regions are myong-dang(明堂), eyes(眼) and In-dang(印堂). Myong-dang(明堂) indicates nose. In-dang(印堂) indicates the space between eyebrows. Unlike myong-dang(印堂) and eyes, In-dang(印堂) is occasionally treated as a trivial region then others. But, from research on classical books of facial examination and consideration of it's locational meanings, we've learned In-dang(印堂) is very important in viewing diagnosis, because this region is crossing of the other two regions and this fact means this region expresses the spiritual status as well as physical status in one region.

Reverse transcription and polymerase chain reaction (RT-PCR) techiniques were used to identification and differentiation of cucumber mosaic virus isolated from Forsythia koreana (CMV-Fk). RT-PCT used by two set of 20-mer primers one was CMV-common primers and another was CMV subgroup I-specific primers designed in a conserved region of the 3' end of CMV RNA3, amplified about 490 bp and 200 bp DNA fragments from CMV-Fk, respectively. CMV could be detected by RT-PCR at a dilution as low as 10-4 in forsythia crude sap extracts. Restriction enzyme analysis of RT-PCR products using EcoRI and MspI showed that CMV-Fk belonged to CMV subgroup I. But, analysis of RNA fingerprinting by arbitrarily primed polymerase chain reaction (RAP-PCR) showed heterogeneity of RNA3 between CMV-Fk and CMV-Y as a member of subgroup I.

Dynamic structures of unsteady $CH_4$/Air jet diffusion flames with flame-vortex interaction were numerically investigated. A time-dependent, axisymmetric computational model was adopted for this calculation. Two step global reaction mechanism which considers 6 species, was used to calculate the reaction rates. The predicted results including gravitational effect show that the large outer vortices and the small inner vortex street can be well simulated without any additional disturbances in the downstream of nozzle tip. It was found that the temperature and species concentrations had various values for the same mixture fraction in flame-vortex interaction region. This unsteady jet flame configuration accompanying flame-vortex interaction is expected to give good implications for the structure of turbulent flames.

The spontaneous ignition mechanism of high pressure hydrogen gas released into tube is well-deduced from previous studies. However, those results have a limit because the studies have been conducted at low burst pressure of about 10 MPa. In this study, the process or ignition feature are investigated with higher burst pressure of up to 30 MPa through numerical analysis. The results show that the trend of ignition became to be different with a burst pressure. While two reaction regions is important to initiate the ignition when burst pressure is about 10 MPa, the reaction of the core region does not play a role in ignition inside the tube when a burst pressure is above 20 MPa.
