  • LBH is a transcription factor as a candidate gene for CHD associated with partial trisomy 2p syndrome. To identify potential LBH-interacting partners, a yeast two-hybrid screen using LBH as a bait was performed with a human heart cDNA library. One of the clones identified encodes ${\alpha}B$-crystallin. Co-immunoprecipitation and GST pull-down assays showed that LBH interacts with ${\alpha}B$-crystallin, which is further confirmed by mammalian two-hybrid assays. Co-localization analysis showed that in COS-7 cells, ${\alpha}B$-crystallin that is cytoplasmic alone, accumulates partialy in the nucleus when co-transfected with LBH. Transient transfection assays indicated that overexpression of LBH or ${\alpha}B$-crystallin reduced the transcriptional activities of p53 and p21, respectively, Overexpression of both ${\alpha}B$-crystallin and LBH together resulted in a stronger repression of the transcriptional activities of p21 and p53. These results showed that the interaction of LBH and ${\alpha}B$-crystallin may inhibit synergistically the transcriptional regulation of p53 and p21.

  • Zinc finger (ZNF) proteins play a critical role in cell growth, proliferation, apoptosis, and intracellular signal transduction. In this paper, we cloned and characterized a novel human KRAB-related zinc finger gene, ZNF425, which encodes a protein of 752 amino acids. ZNF425 is strongly expressed in the three month old human embryos and then is almost undetectable in six month old embryos and in adult tissues. An EGFP-ZNF425 fusion protein can be found in both the nucleus and the cytoplasm. ZNF425 appears to act as a transcription repressor. Over-expression of ZNF425 inhibits the transcriptional activities of SRE, AP-1, and SRF. Deletion analysis indicates that the C2H2 domain is the main region responsible for the repression. Our results suggest that the ZNF425 gene is a new transcriptional inhibitor that functions in the MAPK signaling pathway.

  • Hot springs development will be more activated with the five-day work week system than before. Nevertheless, investment and development achievement of hot springs has not resulted in a successful performance to foster townships, and this calls upon locals to build a guideline to develop hot springs. This study intends to analyze laws on hot springs, which influence mostly on the hot spring development, to gather up the information on the present state of the development, and to suggest considerations for further development plans. Features of the hot spring development are as follows: One is that metropolitan cities will discover hot spring resources more than small cities. Therefore the development will be twofold : one for resort tour and the other for one-day rest and recreation. In addition, Korean laws on hot springs are more site development-oriented to support tourism and recreation than to protect environment and discover unused resources. This makes hot spring development easier and efficient being supported by hot spring law, law on territory development and use, and tourism promotion law. On the other side, planned landscape trimming can be uniformized and unharmonized in terms of local identity and environment-friendliness. This is why careful considerations such as goods and bads of the local resources, local history and culture are needed in hot spring development. A long-term development project should include remodeling based on local identity and development trends. The third point indicates that Korean hot springs development has recorded relatively low performance due to difficult private capital attraction, and a high fence on land purchase and development approval. It is essential to release restrictions on the hot spring development-especially on those whose development performance has not been successful so that best practice can be supported by the government in remodeling and marketing. New plans on hot spring development should be also examined based on developer's capacity and local authorities' volition on the plan. Last point shows that most hot springs development plans have been designed only based on territory utilizing plan and facilities arrangement, not considering much on fund-raising, operational plan or feasibility analysis. Therefore the tourism promotion law should reinforce guidelines on tourist site approval system by supplementing criteria. At the same time, an education on tourism development planning is necessary to deepen developers' understanding, since most developers are experts more on city development, landscape architecture, designing, constructing and engineering than tourism development.

  • Belitung district in Bangka-Belitung Province, Indonesia with a population of 0.27 million is endemic for Brugia malayi and 5 rounds of mass drug administration (MDA) were completed by 2010. Based on the results of 3 transmission assessment surveys (TAS), the district is declared as achieving elimination of lymphatic filariasis (LF) in 2017. The findings of an independent survey conducted by the National Institute of Health Research and Development (NIHRD) in the same year showed microfilaria (Mf) prevalence of 1.3% in this district. In 2019, NIHRD conducted microfilaria survey in 2 villages in Belitung district. Screening of 311 and 360 individuals in Lasar and Suak Gual villages showed Mf prevalence of 5.1% and 2.2% with mean Mf density of 120 and 354 mf/ml in the respective villages. Mf prevalence was significantly higher among farmers and fishermen compared to others and the gender specific difference was not significant. The results of a questionnaire based interview showed that 62.4% of the respondents reported to have participated in MDA in Lasar while it was 57.7% in Suak Gual village. About 42% of the Mf positive cases did not participate in MDA. Environmental surveys identified many swampy areas supporting the breeding of Mansonia vector species. Persistence of infection is evident and in the event of successful TAS3 it is necessary to monitor the situation and plan for focal MDA. Appropriate surveillance strategies including xenomonitoring in post-MDA situations need to be developed to prevent resurgence of infection. Possible role of animal reservoirs is discussed.

  • The station area development planed to improve the old and narrowed station and to enhance the train passenger's convenience through private capital attraction in the past. But it has been faced with difficulty for the creative of transfer demand. Because of lean upon building facilities were caused by shortage of business profitability as to development of the upside a railway line, and lack of public utilities. The station area development requires that it's trend to large scale development of station areas, korail's direct development, deputation of specialty company to development, collaboration between local government and korail in development, diversification of process & installed facility, building multi-transfer center and one-stop transfer system. This trend caused by low profitability in development of the upside a railway line. The purposes of study are to make the system and law reflected to the property of station area development, investment in kind of needed land, and change railroad areas to high-rise and complex development, and make a forum between government and korail, etc.

  • In Harbin, a network of underground commercial spaces has been developed to occupy spaces that were originally created as civil defense shelters. With the gradual extension of the local metro rail system, the existing underground commercial space is no longer an isolated regional development, but a space that represents "three-dimensional city" and coordinated development taking place in many Chinese cities. Based on the analysis of the unique development process taken in underground space of Harbin, this paper summarizes three characteristics of its early model of "fragmented development" of underground space. By conducting a comprehensive field research and survey, the researchers analyzed 472 questionnaires related to the development trend, and proposed multi-level synergistic elements for the renewal and development of underground commercial space. The paper concludes by discussing the trend of "three-dimensional and collaborative development," suitable for the development needs of the new era, and the corresponding development strategies for the renewal of underground space.
