Objectives : This study was designed to explore body-shape satisfaction and adjustment functions in 410 adolescent school girls. Methods : After underweight, normal-weight and overweight groups were identified among 410 high school girls according to BMI(body mass index), we compared current weight & height, ideal weight & height, subtracted value of ideal weight from current weight, subtracted value of ideal height from current height, subtracted value of ideal BMI from current BMI, weight dissatisfaction, height dissatisfaction, body-shape dissatisfaction, and EAT-26(Eating Attitude Test-26), OSIQ(Offer Self-Image Questionnaire for Adolescents), STAI (State-Trait Anxiety Inventory), BDI(Beck Depression Inventory), BITE(Bulimic Investigatory Test Edinburgh) among the three groups. Results : 1) The subjects consisted with overweight group(BMI〉25, N=27, 6.6%), normal-weight group(19≤BMI≤25, N=278, 67.8%), and underweight group(BMI〈19, N=105, 25.6%). 2) In comparison to other groups, overweight group was significantly different in subtracted value of ideal weight from current weight and subtracted value of ideal height from current height. These results suggest that overweight group wants greater body-shape change than other groups. Overweight group was significantly shorter in height than underweight group. There were no significant differences in ideal height among the groups. 3) Overweight group and normal-weight group showed significantly higher weight dissatisfaction than underweight group. There were no significant differences in height dissatisfaction and body-shape dissatisfaction among the three groups. All groups showed higher weight, height dissatisfaction and body-shape dissatisfaction except higher weight dissatisfaction in underweight group. 4) In comparison of overweignt group with other groups by mean difference of each scale, there was significant difference in superior adjustment subscale of the OSIQ and symptom subscale of the BITE between overweight group and other groups. There was also significant difference in symptom serenity subscale of the BITE between overweight and underweight groups. There was no significant difference in EAT-26, STAI, BDI, other subscales of OSIQ among the groups. Conclusions : 1) The distribution rate of overweight group was lower than in western studies. 2) These results suggest that overweight group wants greater body-shape change than other groups, and overweight group may have binge-eating and poor coping system.

본 논문에서는 사용후핵연료의 처분을 위한 지하공동구조체의 수치해석에 대한 내용을 소개하였다. 수치해석에는 사용후핵연료 처분의 기준개념인 KBS-3의 자료가 사용되었으며, 처분용기의 열발생에 의한 영향과 공동주변 암반체의 지하수 흐름 영향을 고려한 열-수리-역학적 연계해석개념이 사용되었다. 해석결과 사용후핵연료 처분용기의 설치 4년후에 처분용기표면의 온도는 120"C로 최대값을 나타냈으며, 공동주변 암반체의 온도와 변위는 10년후에 최대값을 나타냄을 알 수 있었다. 또한 처분용기를 설치하고 20년후에 공동주변암반체에 공극수압의 증가로 인한 공동으로의 최대 지하수유입이 나타남을 알 수 있었다. A numerical study of reference concepts for the disposal of spent nuclear fuel it presented in this paper. Main input parameters used in this study are determined from the KBS-3 concept. Coupled thermal-hydraulic-mechanical analysis considering the effects of temperature and groundwater flow to simulate the deep disposal system of spent nuclear fuel in saturated rock mass is adapted. It is shown that numerical results of maximum temperature at the suface of canister are more than about 120℃ at about 4 years after the emplacement of spent nuclear fuel and that those of the temperature distribution around an underground opening reach the maximum value at about 10 years. Itt is also shown that the maximum upward displacement due to the heat generation of spent nuclear fuel is about 0.9 cm at about 10 years after the emplacement of that. Finally, to quantity of groundwater inflow into an underground disposal opening increased by about 1.6 times at 20 years after the emplacement of that with the increase of pore pressure around an opening.

Background: High risks of fire alway exist for buildings in urban areas, especially those in downtown. Crowds, as well as more complex and larger structures, may cause more victims in the event of fire; therefore, emergency medical service plans must be established for such disastrous events. Methods: On the evening of October 30,1999, a fire broke out in downtown, Dong-Incheon Live-Hof restaurant; 56 people were killed and 76 were injured. Most of them were teenagers. We retrospectively reviewed the medical records of the victims, Results: 1) Among the 56 dead, 54 died from smoke inhalation, one from extensive burns, and one from sepsis during treatment. 2) Among the 76 injured, 70 patients suffered from smoke inhalation, 53 from burns, and 9 from several types of trauma (sprains, contusions, lacerations, abrasions, fractures, etc.). 3) Later complications were laryngeal edema, pulmonary edema, scar contracture, and hypoxic brain damage, and so forth. 4) Post traumatic stress syndrome was unexpectedly more prevalent in mildly to moderately injured survivors and witnesses than in seriously injured survivors. Conclusion: Many complications exist after a fire. Some may be resolved in time, but others may result in permanent sequelae. Early rescue, early triage, and early management during transport by emergency medical service (EMS) personnel can result in fewer complications and a lower mortality rate. Therefore, we propose the establishment of plans to be followed during various major disasters.

Ionizing radiation is known to cause chromosomal alterations such as inversions and deletions and affects gene expression within the plant genome. To monitor the genome-wide transcriptome changes by ionizing radiation, we used rice Affimetrix GeneChip microarray to identify genes that are up- or down regulated by gamma-ray (200 Gy, 60Co source), cosmic-ray and ion beam (40 Gy, 220 MeV carbon ion). The overall expression patterns between gamma-ray and ion beam were similar but cosmic-ray was regulated differently. Combined results from all 3 radiations identified 27 up-regulated genes and 188 down regulated genes. These results mean the induction of similar mechanism changes in treatments of gamma ray and ion beam. However the different expression in treatment of cosmic-ray might be due to the other environmental conditions. Among the commonly up- or down- regulated genes, we chose highly up- or down- regulated several genes and confirmed its regulation in response to ionizing radiation exposure by RT-PCR analysis. Moreover, we showed that specific co-expression networks of candidate radio marker genes by ARACNE algorithm. Our results present profiles of gene expression related to different ionizing radiation and marker gene to predict sensitivity to ionizing radiation, such as GS (glutelin subunit) and FBX322.

Generation of Reactive Oxygen Species in Bovine Somatic Cell Nuclear Transfer Embryos during Micromanipulation Procedures

Hwang, In-Sun,Bae, Hyo-Kyung,Park, Choon-Keun,Yang, Boo-Keun,Cheong, Hee-Tae The Korean Society of Animal Reproduction 2012 Reproductive & developmental biology Vol.36 No.1

The present study was conducted to examine the generation of reactive oxygen species (ROS) during micromanipulation procedures in bovine somatic cell nuclear transfer (SCNT) embryos. Bovine enucleated oocytes were electrofused with donor cells, activated by a combination of Ca-ionophore and 6-dimethylaminopurine culture. Oocytes and embryos were stained in dichlorodihydrofluorescein diacetate or 3'-(p-hydroxyphenyl) fluorescein dye and the $H_2O_2$ or $^.OH$ radical levels were measured. $In$ $vitro$ fertilization (IVF) was performed for controls. The samples were examined with a fluorescent microscope, and fluorescence intensity was analyzed in each oocyte and embryo. The $H_2O_2$ and $^.OH$ radical levels of reconstituted oocytes were increased during manipulation (37.2~49.7 and 51.0~55.2 pixels, respectively) as compared to those of mature oocytes ($p$<0.05). During early $In$ $vitro$ culture, the ROS levels of SCNT embryos were significantly higher than those of IVF embryos ($p$<0.05). These results suggest that the cellular stress during micromanipulation procedures can generate the ROS in bovine SCNT embryos.

Generation of Reactive Oxygen Species in Porcine Parthenogenetic Embryos

Hwang, In-Sun,Park, Choon-Keun,Yang, Boo-Keun,Cheong, Hee-Tae The Korean Society of Animal Reproduction 2011 Reproductive & developmental biology Vol.35 No.2

The present study was conducted to examine the reactive oxygen species (ROS) generation levels in porcine parthenogenetic embryos. Porcine in vitro matured oocytes were activated by the combination of electric stimulus and 6-DMAP before in vitro culture. Porcine oocytes and parthenogenetic embryos were stained in 10 ${\mu}M$ dichlorohydrofluorescein diacetate (DCF) or 10 ${\mu}M$ hydroxyphenyl fluorescein (HPF) dye each for 30 min at $39^{\circ}C$. The fluorescent emissions from the samples were recoded as JPEG file and the intensity of fluorescence in oocytes and embryos were analyzed. $H_2O_2$ and $^{\cdot}OH$ radical levels of porcine oocytes were reduced immediately after electric stimulation. However, $H_2O_2$ and $^{\cdot}OH$ radical levels of parthenogenetic embryos were increased with time elapsed after electric stimulation from 0 h to 3 h and after DMAP culture. During in vitro culture, $H_2O_2$ and $^{\cdot}OH$ radical levels were gradually increased from the one-cell stage to the two- and four-cell stages. The result of the present study suggests that the ROS was not increased by electric pulse in porcine embryos. Rather than it seems to be associated with the stage of development and the culture condition.

Hwang, In-Sul,Kwon, Dae-Jin,Oh, Keun Bong,Ock, Sun-A,Chung, Hak-Jae,Cho, In-Cheol,Lee, Jeong-Woong,Im, Gi-Sun,Hwang, Seongsoo The Korean Society of Developmental Biology 2015 발생과 생식 Vol.19 No.2

The Korean native pig (KNP) have been considered as animal models for animal biotechnology research because of their relatively small body size and their presumably highly inbred status due to the closed breeding program. However, little is reported about the use of KNP for animal biotechnology researches. This study was performed to establish the somatic cell nuclear transfer (SCNT) protocol for the production of swine leukocyte antigens (SLA) homotype-defined SCNT KNP. The ear fibroblast cells originated from KNP were cultured and used as donor cell. After thawing, the donor cells were cultured for 1 hour with 15 ${\mu}M$ roscovitine prior to the nuclear transfer. The numbers of reconstructed and parthenogenetic embryos transferred were $98{\pm}35.2$ and $145{\pm}11.2$, respectively. The pregnancy and delivery rate were 3/5 (60%) and 2/5 (40%). One healthy SLA homotype-defined SCNT KNP was successfully generated. The recipient-based individual cloning efficiency ranged from 0.65 to 1.08%. Taken together, it can be postulated that the methodological establishment of the production of SLA homotype-defined cloned KNP can be applied to the generation of transgenic cloned KNP as model animals for human disease and xenotransplantation researches.

Hwang, Jung Eun,Hwang, Sun‐,Goo,Kim, Sun‐,Hee,Lee, Kyung Jun,Jang, Cheol Seong,Kim, Jin‐,Baek,Kim, Sang Hoon,Ha, Bo‐,Keun,Ahn, Joon‐,Woo,Kang, Si‐,Yong,Kim, Dong Su Blackwell Publishing Ltd 2014 Physiologia plantarum Vol.150 No.4

<P>Ionizing radiation (IR) affects gene expression from plant genomes. To monitor the genome‐wide transcriptional changes induced by three types of IR, we used the rice Affymetrix GeneChip microarray to identify genes that are up‐ or down‐regulated by gamma rays (GAs), cosmic rays (CRs) and ion beams (IBs). The overall expression patterns in rice seedlings generated from seeds exposed to GAs and IBs were similar but differed for CRs exposure. Expression profiles of genes involved in metabolic pathways and cellular response were identified using <SMALL>MapMan</SMALL> analysis. This result revealed that IRs induced gene expression related to sucrose–starch metabolisms; sugar and starch accumulation was significantly increased in response to three types of IR in rice. In addition, we compared the genes commonly up‐ or down‐regulated by exposure to three types of IR and identified 53 candidate radio marker genes (RMGs) that were differentially regulated by radiation exposure but not by other stresses. Among these genes, we selected six RMGs commonly applicable to different types of IR by specific coexpression networks using the algorithm for the reconstruction of accurate cellular networks (<SMALL>aracne)</SMALL> and confirmed the expression of these genes by reverse transcription‐polymerase chain reaction (RT‐PCR) analysis. Our results provided insight into the mechanisms of the responses to different types of IR and identified multiple marker genes to predict sensitivity to three types of IR.</P>
