  • To establish the indoor-rearing system of the emma field cricket, Teleogryllus emma, the effects of temperature on development and reproduction of the emma cricket have been studied. The influence of temperature on developmental periods of emma field cricket was investigated under the eight temperatures of 15, 18, 21, 25, 27, 29, 31 and $35^{\circ}C$, under $60{\pm}5%$ R.H. and 16L:8D photoperiod. The developmental periods of T. emma nymphs had a range of 124.8 days to 44.4 days at the temperature of $21^{\circ}C$ and $35^{\circ}C$, respectively. At $15^{\circ}C$ and $18^{\circ}C$, however, all tested individuals died before emergence. The highest survival rate was 90% at $25^{\circ}C$, but there were no statistically significant differences among the temperatures. The adult weight increased with increasing temperatures although the weight at $35^{\circ}C$ was decreased. In addition, the influence of temperature on reproduction of emma field cricket was investigated under three temperatures $22^{\circ}C,\;25^{\circ}C\;and\;28^{\circ}C$, under $60{\pm}5%$ R.H. and 16L:8D photoperiod. The longevity of female/male adults were 65.8/79.2 days, 68.5/67.8 days, 46.8/57.4 days at the temperature $22^{\circ}C,\;25^{\circ}C\;and\;28^{\circ}C$, respectively. The preoviposition periods were 32.5 days at $22^{\circ}C,\;22.9^{\circ}C$ days at $25^{\circ}C$ and 22.1 days at $28^{\circ}C$. The highest average fecundity per female was 737.3 at $25^{\circ}C$.

  • Purpose: The purpose of this study was to investigate the leg length Inequality, habitual posture, and pain in women's college students. Methods: The subjects were 281 students, in 8 women's college in Korea. The tapelines were used for measuring leg length Inequality and questionnaires were used for measuring habitual posture, and pain. The data were collected between August and October 2010 and analyzed using SPSSWIN 11.5. length Inequality(<1 cm). The subjects of 2.8% were the length differences of above 2cm. The worst habitual posture were leaning habits. Especially, the habits of crossing her legs were significantly different to leg length Inequality(F=3.342, $p$=.037). The subjects of 84% were felt a severe pain on the upper body such as waist, back, scapula, neck or shoulder. But there is no difference between pain and leg length Inequality. Habitual posture are related to pain(r=.212, $p$=.001). Conclusion: To protect the severe health problem of musculoskeletal system, this study results will be give aid to health education in women's college students.

  • To investigate the expression of hPOT1 in the HeLa cell line and screen point mutations of hpot1 in different tumor tissues a two step osmotic method was used to extract nuclear proteins. EMSA was performed to determine the expression of hPOT1 in the HeLa cell line. PCR was also employed to amplify the exon14 sequence of the hpot1 gene in various of cancer tissues. A SV gel and PCR clean-up system was performed to enrich PCR products. DNAStar was used to analyse the exon14 sequence of the hpot1 gene. hPOT1 was expressed in the HeLa cell line and the signal was gradually enhanced as the amount of extracted nuclear proteins increased. The DNA fragment of exon14 of hpot1 was successfully amplified in the HeLa cell line and all cancer tissues, point mutations being observed in 2 out of 3 cases of endometrial cancer (66.7%) despite the hpot1 sequence being highly conserved. However, the sequence of hpot1 exon14 do not demonstrate point mutations in most cancer tissues. Since hPOT1 was expressed in HeLa cell and the probability of gene point variants was obviously higher in endometrial cancer than other cancers, it may be involved in the pathogenesis of gynecological cancers, especially in cervix and endometrium.

  • Objectives : The mesolimbic dopamine system is believed to play a major role in the reinforcing effect and behavioral hyperactivity of abused drugs including methamphetamine. In the present study, the effect of acupuncture on methamphetamine-induced locomotor activity and c-Fos expression in the striatum and nucleus accumbens of rats were examined. Methods : Male Sprague-Dawley rats received acupuncture at bilateral Yanggu($SI_5$) point for 30seconds immediately before the subcutaneous injection of saline or methamphetamine(0.5mg/kg). The total amount of locomotor activity for 90min were measured just before brain samples were taken for immunohistochemistry. Results : Results showed that acupuncture at the specific point $SI_5$, but not control point(Kunlun, $BL_{60}$) significantly reduced locomotor activity and c-Fos expression in the striatum and nucleus accumbens induced by acute administration of methamphetamine. Conclusions : These results suggest that acupuncture may be effective in suppressing the reinforcing effect of methamphetamine by regulating neuronal activity.

  • This study aims to understand the current state of a community project in Seoul and to determine a revitalization plan for community projects of inhabitants initiative. Regarding the research methods, 10 apartments that participated in this activation project in Seoul were selected, 31 residents who participated in community activities were surveyed, and 20 community planners in Seoul were surveyed. The results indicate that community leaders are the most important factor in community programs. community leaders must be able to promote participation and a spirit of service; they must also be capable of managing and implementing programs. To ensure that local community resources are utilized and integrated, it was shown that consultation and human resources are of the highest necessity. Moreover, regarding community education, it was shown that for providing general opportunities and means by which community activities may be implemented, program information and space applications are crucial. Furthermore, financial support and support for public relations activities from the government are necessary. To activate apartment communities, first, community education programs for residents must be provided. Second, a system that facilitates access to and sharing of resources from areas outside the community must be established. Third, financial support should be consistent to support community activities. Finally, the promotion of community vitalization at the government level is necessary.

  • The purpose of this study was to examine the changes and the characteristics of the attitudes toward children and spaces provided for them. by analyzing people's daily lives in housing spaces and architects' floor plans between the 1920s and the 1960s. Different kinds of data were obtained from a variety of early literature, research reports, newspaper articles, historical documents, and magazines from the period. Findings of this study are as follows: 1. Before modernization in Korea, children had been regarded as immature persons. Confucian ideas of children viewed them as 'small adults' or 'immature adults.' Thus spaces for children's daily lives were neither differentiated from those of the adults' nor deemed important. However, since the Western invasions and colonization by Japan, a remarkable change in the attitudes toward children took place. Children began to be considered a hope for the future as well as members of modem families. In addition, the introduction of the new word, 'eorini (children),' by Mr. Bang Jeonghwan, brought about a significant change in social consciousness of children. 2. The appearance of 'adongshil (children's room)' on architects' floor plans, which was a result of the social critique against androcentrism during the l930s and 1940s, was highly meaningful. The new floor plans not only emphasized rationalization of the space but also upgraded the children's status in the family. 3. Since the liberation (1945), children's space was differentiated from parental spare by the introduction of private rooms and shared spaces. The privacy of each generation was expressed by the division, and the generations were considered equal in this space distribution. In conclusion, the appearance of children's rooms required conflict-laden changes of social ideals and of the family system. It also was a symbol of modernization.

  • The objective of this study was to investigate the infection rate of gastro-intestinal tract parasites on acquired laboratory nonhuman primates, Vervet monkey, Cynomolgus monkey, and Rhesus monkey acquired from Japan and China. These monkeys have been acclimating at an individual housing condition after our legal quarantine period. We examined 133 fecal samples to investigate parasitic infection using direct smear and formalin-ether-sedimentation technique. As a result, total parasitic infection rate was 33.8% (n = 45/133) for all monkeys. Two species of macaques, cynomolgus and rhesus, were infected with Trichuris trichiura (4), Giardia lamblia (4) and Balantidium coli (41). Vervet monkeys, which had been controlled by individual housing system for a long time, were clear for parasitic infection. The protozoan, Balantidium coli was one of the most frequently detected in these monkey colonies. Double infection was noted in only 4 monkeys and involved with Trichuris trichiura and Balantidium coli. Serious clinical symptoms were not observed in the most of the infected monkeys, but the monkeys infected by Giardia lamblia showed intermittent or chronic watery diarrhea. Consequently, the prophylactic anthelmintic treatment and periodic monitoring are essential to preserve the SPF colonies in the laboratory facility.

  • A new fastness formula based on the CIEDE2000 color-difference formula was developed by B. Rigg and his coworkers. It is much simpler to calculate the staining fastness grade than the ISO 105-A04 fastness formula based on the CIELAB color-difference formula. Sample pair sets, which cover a wide color space range were accumulated from the NCS(Natural Color System) color book. for those sample pair sets, a visual measurement experiment and an instrumental measurement experiment of fastness grade were carried out. Each performance of the ISO 105-A43 fastness formula and newly developed fastness formula was compared through degree of agreement for visual measurement results. The newly developed fastness formula indicated improved performance for measuring fastness grade as it was confirmed that the performance of the current ISO fastness formula ISO 105-A04 for assessing staining, was inadequate for measuring fastness grade. Then the fastness formulae were examined more closely according to the particular color spaces and the correlation of hue, lightness and chroma for measuring staining fastness grade was also considered to recommend more improved fastness formula. By modifying the weighting functions of CIEDE2000, which is a basis of new fastness formula developed by B. Rigg, a modified fastness formula is proposed in this study.

  • Haze or fog is a common natural phenomenon. In foggy weather, the captured pictures are difficult to be applied to computer vision system, such as road traffic detection, target tracking, etc. Therefore, the image dehazing technique has become a hotspot in the field of image processing. This paper presents an overview of the existing achievements on the image dehazing technique. The intent of this paper is not to review all the relevant works that have appeared in the literature, but rather to focus on two main works, that is, image dehazing scheme based on atmospheric veil and image dehazing scheme based on dark channel prior. After the overview and a comparative study, we propose an improved image dehazing method, which is based on two image dehazing schemes mentioned above. Our image dehazing method can obtain the fog-free images by proposing a more desirable atmospheric veil and estimating atmospheric light more accurately. In addition, we adjust the transmission of the sky regions and conduct tone mapping for the obtained images. Compared with other state of the art algorithms, experiment results show that images recovered by our algorithm are clearer and more natural, especially at distant scene and places where scene depth jumps abruptly.

  • Aims: To study KIT (CD117) expression in thymic epithelial tumors in China, and investigate diagnostic and clinical significance. Material and Methods: Thymic epithelial tumors (TETs) from 102 patients (3 type A, 29 type AB, 5 type B1, 22 type B2, 29 typeB3 and 16 thymic carcinomas) were examined. Immunohistochemical staining with an antic-kit monoclonal antibody was performed on a tissue microarray. Relationships between KIT positive expression and the TET clinical characteristics (WHO histologic classification and Masaoka stage system) were analysed. Results: The KIT positive expression rate was significantly higher in thymic carcinoma (60%, 9/16) than in thymoma (8%, 7/86), a strong correlation being found with the WHO classification, but not the Masaoka tumor stage. The overall survival for patients with KIT positive lesions was significantly worse. Conclusions: KIT is a good molecule marker to differentially diagnose thymic carcinoma from thymoma, while also serving as a predictor of prognosis for TETs. Further research into KIT mutations in Chinese TETs should be conducted to assess the efficacy of targeted therapy.
