This paper presents a method for precisely localizing and parking of bimodal trams. In order to gain an automatically driving system for bimodal trams, precise up-to-date localization, velocity recognition, distance to next station and precise parking location estimation functions are required. This paper proposes a system consisting of control device, steering device, sensor input equipment, driving system, tachometer, vehicle-side sensors, magnetic markers and magnetic sensors. The tram recognizes the precise location via magnetic markers containing information. Parking position and precise distance calculation is embodied by a tachometer. The vehicle-side sensors are used to assure safe station approaching and parking magnetic markers provide improvement of precision while tram parking. This paper provides a system realizing localization and precise parking and afterwards the automatic drive test results are reported and analyzed.

This work aimed to analyze current status of by-products generation and industrial symbiosis network in Gyeongsangbuk-do, South Korea. Manufacturing sector of the province mainly consists of electronics, machinery, steel, metal-working industries. Gumi and Pohang have the 1st and 2nd largest worker population in the manufacturing sector. 21,950.7 ton/d of waste is generated from the industries in 2011, of which 82.2% is recycled. The industrial waste, which is not recycled, is mainly composed of sludge cake from domestic wastewater treatment plants, waste plastic, incinerator ash, and slag. Pohang is the largest generating city of both total and the non-recycled industrial waste in the province, and most of the waste is from Pohang steel industrial park. Symbiosis map in Pohang steel industrial park shows that most of the current material symbiosis in the industrial park is for waste refractories and slag.

The purpose of this study are to develop a SDSS (Spatial Decision Support System) that can incorporate diverse opinions of stakeholders related the designation of protected areas (PA), and to employ the model for the readjustment of the boundary line of the Jirisan National Park of Korea. The SDSS would lead to more rational and less controversial decision-making during the expansion or removal of PA in Korea. Research methods are as follows. Firstly, to select evaluation criteria for SDSS for PA designation by using expert interview and literature survey. Secondly, to measure their preferences on the designation of additional PA or the removal of a part of PA based on the opinions of various stakeholders such as local residents, environmental groups, or public officials. Thirdly, to produce conservation priority maps based on a multi-criteria decision making technique. The SDSS would be used to rational decision making for the expansion of PA or the release of a certain part of PA by reflecting diverse preferences on biodiversity conservation and economic interest of residents. The visualization of conservation priority maps would also increase the efficiency of such decision making processes. The evaluation criteria for the expansion of PA for biodiversity conservation includes vegetation conservation value, wildlife conservation value, and the habitats of key species. The evaluation criteria for the removal of PA includes the proximity to roads and the boundary of PA, land use types, and conservation zoning of the PA. Preference weights are based on data collected from the Jirisan National Park. Both the conservation priority and removal priority maps are based on land parcels so that property rights of all parcels would be correctly represented.

국내 팔색조(Pitta nympha) 분포 현황을 알아보고자 전국 국립공원 등 보호지역 중심으로 총 19개 지역을 조사하였고, 전문가 네트워크를 통해 자료를 보강하였다. 전국 19개 지역을 조사한 결과 북한산, 지리산 등 내륙지역 7개 국립공원에서는 팔색조가 확인되지 않았고, 경남 거제, 남해, 해남, 장흥 고흥 등 남해안과 인접한 12개 지역에서 팔색조 서식이 확인되었다. 또한 전문가 네트워크를 통해 수집한 팔색조 출현 위치 정보 82건을 분석한 결과, 전국 8개 광역지자체 모두 팔색조 서식이 확인되었고, 내륙지역(26.8%)보다 해안지역(73.2%)에서 더 많이 출현하였다. 연구 결과를 종합해보면, 우리나라의 팔색조는 주로 제주도와 남해안 지역을 중심으로 많이 분포하며, 그 보다 적은 개체수가 내륙 지역에 넓게 분포하고 있는 것으로 나타났다. The present study investigated the current distribution of Fairy Pitta (Pitta nympha) in South Korea. A total of 19 study areas, including protected areas such as national and provincial parks in South Korea were surveyed, and additional data obtained from an expert network. According to the results, Fairy Pitta was absent in seven inland national parks, including Mt. Bukhan and Chiri parks. Fairy Pitta inhabited 12 areas near the southern coast of South Korea, including Geoje, Namhae, Haenam, Jangheung, Goheung, and Gyeongnam Province. The analysis results of 82 datasets obtained from experts with regard to the locations where Fairy Pitta have been spotted showed that the bird inhabits all the eight metropolitan regions in South Korea, and is more frequently spotted in coastal areas (73.2%) than in inland areas (26.8%). The findings demonstrate that Fairy Pitta is mainly distributed in Jeju Island and the southern coast of South Korea, and is distributed in inland areas at relatively lower numbers.

<P><B>Abstract</B></P><P>MK801 (dizocilpine) induces selective neurotoxic effects in the retrosplenial cortex, ranging from neuronal vacuolization to irreversible neurodegeneration depending on the dose administered. Although lamotrigine prevents MK801-induced neuronal vacuolization in the retrosplenial cortex 4?h after injection, it is not clear whether lamotrigine attenuates the subsequent neurodegeneration that occurs 3–4?days later. Because early growth response factor-1 (egr-1) plays a key role in neurodegeneration and its expression is induced in the retrosplenial cortex following MK801 treatment, it is possible that lamotrigine may attenuate MK801-induced neurodegeneration via inhibition of egr-1 expression in the retrosplenial cortex. To address this issue, we treated rats with lamotrigine (10 or 20?mg/kg) followed by MK801 (2?mg/kg) and measured changes in the levels of egr-1 mRNA and immunoreactivity in the retrosplenial cortex and other brain regions 3?h later. We also evaluated the effects of these treatments on neurodegeneration 4?days following treatment using Fluoro-Jade B staining. MK801 treatment increased egr-1 mRNA and immunoreactivity in the restrosplenial, cingulate, entorhinal and piriform cortices, but decreased levels in hippocampal subfields. These MK801-induced changes in egr-1 expression were significantly inhibited by lamotrigine pretreatment. In addition, MK801-induced neurodegeneration in the retrosplenial cortex was partially blocked by lamotrigine pretreatment in a dose dependent manner. These results demonstrate that lamotrigine pretreatment prevents the MK801-induced upregulation of egr-1 expression in a region-selective manner, and suggest that this effect may contribute, in part, to the attenuation of MK801-induced neurodegeneration in the retrosplenial cortex.</P>

<P>PURPOSE: This multiinstitutional report assesses the oncologic efficacy of hand-assisted laparoscopic radical nephrectomy (HLRN) compared with open radical nephrectomy (ORN) in patients with localized clear cell renal-cell carcinoma (RCC). PATIENTS AND METHODS: We analyzed the data from 2561 patients who underwent radical nephrectomy at 26 institutions in Korea between June 1998 and December 2007 for localized RCC. One hundred ninety-seven patients with clear cell RCC in the HLRN group were compared with 917 patients with clear cell RCC in the ORN group. To evaluate the technical adequacy and oncologic outcome, we compared the operative time, estimated blood loss, and 5-year overall and disease-free survival rates. RESULTS: The median follow-up was 36 months for the HLRN group and 27 months for the ORN group. The operative time was significantly longer in the HLRN group than in the ORN group (206.8 +/- 68.7 minutes vs. 179.1 +/- 61.5 minutes, p < 0.001), and blood loss was significantly lower in the HLRN group than in the ORN group (311.6 +/- 238.7 mL vs. 372.4 +/- 367.3 mL, p = 0.003). There was no significant difference in pathologic T stage and Fuhrman's nuclear grade in the two groups. No statistically significant difference was found in the 5-year overall (91.2% vs. 90.3%, p = 0.286) and disease-specific (95.2% vs. 92.1%, p = 0.222) survival rates between the HLRN and ORN groups. CONCLUSIONS: Despite the longer operative time, HLRN was an effective and less-invasive treatment option for localized clear cell RCC. HLRN could achieve cancer control similar to that obtained with ORN.</P>

<P>Helicobacter pylori CopP (HpCopP) is a putative copper binding regulatory protein composed of 66 amino acid residues. The small HpCopP protein is homologous to CopZ, encoded by the E. hirae and B. subtilis cop operons. To clarify the role of HpCopP in copper metabolism in H. pylori, we studied the structural and copper binding characteristics by NMR spectroscopy. Based on the resonance assignments, the tertiary structure of HpCopP was determined. Unlike the βαββαβ fold of the homologous CopZ, HpCopP adopts the βαββα fold. The superposition with structures of other bacterial copper binding proteins showed that the global structure of HpCopP follows the general topology of the family, regardless of absence of the C-terminal β-strand. The Cu(I) binding property of HpCopP was well conserved like CopZs: the structural changes due to Cu(I) and Ag(I) bindings were primarily restricted to the metal binding motif (CXXC motif). On the other hand, the Cu(II) binding property of CopP was different with that of CopZ: in the absence of reducing agent, Cu(II) ion oxidized a mutant HpCopP, resulting in disulfide bond formation in the CXXC motif. The Cu(II) ion binding property was evaluated using the mutant HpCopP, in which two amino acids were artificially introduced at the C-terminus, since the reduced state of the CXXC motif was more stabile in the mutant HpCopP without a reducing agent. Here, the structure and copper binding property of HpCopP are discussed in detail. Proteins 2008. © 2008 Wiley-Liss, Inc.</P>
