Anaphothrips obscurus is a cosmopolitan pest feeding on cereals and other grasses. The effects of constant temperatures on the biology of A. obscurus are notwell known. Laboratory studieswere conducted to assess the effects of temperature on the development, survival, longevity, fecundity and population parameter of A. obscurus at six constant temperatures (15, 20, 25, 30, 32, 35 °C). The hatchability was the lowest at 15 °C, the highest at 25 °C and no eggs hatched at 35 °C. Developmental rates increased linearly as the temperature increased. The lower developmental threshold temperaturewas 10.6 °C and 200 degree-dayswere required to complete development from egg to adult. Adult longevity decreased with increasing temperature, and ranged from 68.87 d at 15 °C to 16.41 d at 32 °C. The highest total fecundity occurred at 20 °Cwith 162 eggs per female. The temperature-dependent total fecundity, age-specific oviposition rate, and age-specific survival rate models were described. The intrinsic rate of increase (rm) was significantly higher at 30 and 32 °C (0.239 and 0.250) than at other temperatures. This study suggests that optimal developmental and reproductive temperatures for A. obscurus ranges between 25 and 30 °C and this may help this species adapt to warmer areas and widen its distribution and potential for damage in response to global warming. These findings will also be useful in developing monitoring programs, population dynamic models, and timing of control measures for A. obscurus.

Exposure to cadmium (Cd) induces apoptosis in osteoblasts (OBs); however, little information is available regarding the specific mechanismsof Cd-induced primary rat OB apoptosis. In this study, Cd reduced cell viability, damaged cell membranes and induced apoptosis in OBs. We observed decreased mitochondrial transmembrane potentials, ultrastructure collapse, enhanced caspase-3 activity, and increasedconcentrations of cleaved PARP, cleaved caspase-9 and cleaved caspase-3 following Cd treatment. Cd also increased the phosphorylationof p38-mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinases (ERK)1/2 and c-jun N-terminal kinase (JNK) in OBs. Pretreatment with the caspase inhibitor, N-benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone, ERK1/2 inhibitor (U0126), p38 inhibitor(SB203580) and JNK inhibitor (SP600125) abrogated Cd-induced cell apoptosis. Furthermore, Cd-treated OBs exhibited signs of oxidativestress protection, including increased antioxidant enzymes superoxide dismutase and glutathione reductase levels and decreased formationof reactive oxygen species. Taken together, the results of our study clarified that Cd has direct cytotoxic effects on OBs, which are mediatedby caspase- and MAPK pathways in Cd-induced apoptosis of OBs.

Anaphothrips obscurus (Müller) is a cosmopolitan pest feeding on cereal crops and grasses. This species exhibits wing polyphenism. Differences in the life history traits of female macropterous and brachypterous A. obscurus were compared in the laboratory for this study. Experiments were performed in climate chambers set at 20 and 25 ± 1 °C, 60 ± 10% RH under a 16 L:8D photoperiod. The duration of total pre-adult stage, adult preoviposition period and total pre-oviposition period of macropterous morphs were significantly longer than in the brachypterous morphs both at 20 and 25 °C. No significant differenceswere found in adult longevity, survival rate or total fecundity between the twowingmorphs,while early fecunditywas significantly higher for brachypterous females compared with that for macropterous females at two temperatures.

A neutral polysaccharide, GP, was isolated from a fermentation broth of Ganoderma lucidum. Acid hydrolysis and a paper chromatography analysis indicated that the polysacchride was composed of glucose, xylose, and mannose. The molecular weight was estimated to be 2.9×10(4). The oral administration of GP to mice showed that it can inhibit liver damage induced by GalN and CCl4.

Although standards have a significant effect on economic growth in the construction industry, the effect of engineering constructionstandards on construction industry economics remains a relatively unexplored subject. In theory, standards as a technology indicatorhave an impact on economic growth. Therefore, we investigate the relationships between engineering construction standards andeconomic growth in the construction industry. A Cobb-Douglas production function and a VAR model are established to explorerelationships between engineering construction standards and economic growth in the construction industry. Our results suggest thatco-integration relationships are evidenced between engineering construction standards and economic growth in the constructionindustry, and engineering construction standards have a positive effect on economic growth in the construction industry.

Coenurosis is an important zoonotic helminthic disease caused by the larval stage of the tapeworm Taenia multiceps. This parasite typically infects the brain of the intermediate hosts, including sheep, goat, cattle and even hu- mans. We report a case of T. multiceps infection in a yak confirmed by clinical symptoms, morphological characteristics, and molecular and phylogenetic analyses. The coenurus was thin-walled, whitish, and spherical in shape with a diameter of 10 cm. The parasite species was identified as T. multiceps by PCR amplification and sequencing of the 18S rRNA, cox1 and nad1 genes. Three gene sequences all showed high homology (all above 97%) with the reference sequences from different hosts. Moreover, phylogenetic reconstructions with the 3 published Taenia gene sequences confirmed that the Qinghai yak isolate was closely related to T. multiceps. Although there are advanced diagnosis and treatment meth- ods for coenurosis, early infection is difficult to diagnose. Importantly, the findings of yak infection case should not be ig- nored due to its zoonotic potential.
기획특집 : 아시아-태평양 지역의 이주와 트랜스내셔널리즘 ; 김노의 작품에 재현된 재한 중국조선족 여성상

본 논문은 김노의 단편들에 재현된 조선족 여성 형상의 문제를 페미니즘과 사회학적 시각에 입각하여 분석하고 이를 통하여 조선적 여성들이 이국땅에서 직면해 온 정체성과 주체, 소외의 문제들을 다룬다. 김노는 중국 길림성 출신으로 1990년대 이후로 작품 활동을 계속해 온 조선족 여성 가인데, 그의 많은 작품들이 국제결혼을 통해 한국 사회에 진입해서 살된 조선족 여성들의 삶과 감정을 다루고 있다. 김노의 작품에 드러난 조선족 여성들의 문제를 살핌에 있어서 본 논문은 특히 주체성의 상실, 정성을 둘러싼 문제들, 한국 사회에서 주변화 되어 목소리를 잃고 타자화 는 여성들의 이중 소외 경험을 다룬다. 나아가 이들 조선족 여성들이 자들의 잃어버린 주체성을 되찾고 목소리를 다시 얻기 위해 이 사회에 드리운 성적, 계급적 억압을 뚫고 어떻게 맞서 싸우는지 그 과정에 주목한다. This paper is a tentative analysis of Korean Chinese female images depicted in Kim Naw's short stories from a feminist and sociological perspectives. Kim Naw is a contemporary Korean Chinese female writer who started her writing career since 1990s. Most of her short stories focus on the lives and emotions of Korean Chinese women who emigrated to the Republic of Korea through international marriage. This paper examines the problems of these women demonstrated in Kim Naw's works. It explores the causes of their suffering from the loss of subjectivity, identity trouble and being silenced and marginalized in the Korean society as "the other" It intends to capture the Korean Chinese women's efforts to break through the interwoven suppression of gender and class in order to regain their subjectivity and rights of voice.

Background: Sirtuin7 (SIRT7) is a type of nicotinamide adenine dinucleotide oxidized form (NAD+)-dependent deacetylase and the least understood member of the sirtuins family; it is implicated in various processes, such as aging, DNA damage repair and cell signaling transduction. There is some evidence that SIRT7 may function as a tumor trigger for human malignancy. Here, we aimed to explore the biological function of SIRT7 in ovarian carcinoma cells and its potential mechanism. Materials and Methods: Expression of SIRT7 in ovarian cancer cell lines was detected by western blotting. Transduced cell lines with SIRT7 knockdown or overexpression were constructed. Cell viability, cologenic, apoptosis-associated and motility assays were performed to elucidate the biological function of SIRT7 in ovarian cancer cells. Results: SIRT7 demonstrated a higher level in ovarian cancer cell lines compared with normal cells. On the one hand, down-regulation of SIRT7 significantly reduced ovarian cancer cell growth, repressed colony formation and increased cancer cell apoptosis; on the other hand, up-regulation promoted the migration of cancer cells. Additionally, repression of SIRT7 also induced change in apoptosis-related molecules and subunits of the NF-${\kappa}B$ family. Conclusions: In the present study, our data indicated that SIRT7 might play a role of oncogene in ovarian malignancy and be a potential therapeutic target.
