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.

Yudeung Bridge, which connects Seo-gu and Jung-gu in Daejeon Metropolitan City, was completed in December 1970. On July 10, 2024, due to heavy rain in the Daejeon area, the bridge piers sank. As a result of an emergency detailed safety inspection, it was concluded that reconstruction was inevitable, and accordingly, the construction of a bypass bridge was carried out as an emergency disaster recovery bid. The D.T.G. (Double Tension Girder) method, which enables long-span construction using strands and anchoring devices, was selected, considering safety, constructability, and especially urgency. The Yudeung temporary bridge (L=173m, B=18.0~32.0m, separated for up and down lanes) was opened in February 2025, 81 days after construction began. The purpose of this study is to examine the safety and constructability of temporary structures through analysis of design and construction cases of long-span temporary bridges.

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>Glucocorticoid receptor (GR) promoter I<SUB>7</SUB> is susceptible to epigenetic changes induced by environmental influences. Early life stress (ELS) has a persistent impact on GR expression, as well as behavior, in adult rodents via epigenetic changes of GR promoter I<SUB>7</SUB>. Moreover, various stressors can induce histone modifications in this region during adulthood. Thus, the present study aimed to investigate whether maternally separated (MS) rats exposed to chronic restraint stress (RS) would exhibit histone modifications of GR promoter I<SUB>7</SUB> in the hippocampus. Rats were subjected to MS (3h per day) on postnatal days (PND) 1–21. Then, during adulthood (PND 56–77), the rats were exposed to RS (2h per day) followed by treatment with escitalopram (10mg/kg). The MS and RS groups exhibited significant decreases in total and exon I<SUB>7</SUB> GR mRNA levels and the combination of MS and RS exerted a greater effect on these mRNA levels than either MS or RS alone. Additionally, both the MS and RS groups showed significant reductions in histone H3 acetylation at GR promoter I<SUB>7</SUB> and the combination of MS and RS had a greater effect than did either MS or RS alone. Chronic escitalopram treatment ameliorated these changes. The present results indicate that postnatal MS and adult RS influence GR expression through histone modification at GR promoter I<SUB>7</SUB>, and that the combination of the two stressors potentiates these changes. Furthermore, epigenetic mechanisms are involved in escitalopram action.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Epigenetic modification of GR promoter I<SUB>7</SUB> is induced by environmental factors. </LI> <LI> Postnatal maternal separation and adult restraint stress reduce the GR expression. </LI> <LI> These stressors reduce the histone H3 acetylation at GR promoter I<SUB>7</SUB>. </LI> <LI> The combination of the two stressors potentiates these reductions. </LI> <LI> These epigenetic changes are recovered by antidepressant drug escitalopram. </LI> </UL> </P>

Lipid-binding properties of TRIM72

( Sung Hyen Kim ),( Jeong Hwa Seo ),( Young Gyu Ko ),( Young Duk Huh ),( Heon Yong Park ) 생화학분자생물학회 2012 BMB Reports Vol.45 No.1

TRIM72 is known to play a critical role in skeletal muscle membrane repair. To better understand the molecular mechanisms of this protein, we carried out an in vitro binding study with TRIM72. Our study proved that TRIM72 binds various lipids with dissociation constants (Kd) ranging from 88.2 ± 9.9 nM to 550.5 ± 134.5 nM. In addition, the intrinsic fluorescence of TRIM72 exponentially decreased when the protein was diluted with stirring. The time-resolved fluorescence decay occurred in a concentration- independent manner. The fluorescence-decayed TRIM72 remained in its secondary structure, but its binding properties were significantly reduced. The dissociation constants (Kd) of fluorescence-decayed TRIM72 for palmitate and stearate were 159.1 ± 39.9 nM and 355.4 ± 106.0 nM, respectively. This study suggests that TRIM72 can be dynamically converted by various stimuli. The results of this study also provide insight into the role of TRIM72 in the repair of sarcolemma damage.
