  • The main purpose of this paper is to provide useful infonnation for residential site design in Korea by analyzing Japanese case. The important characteristics of Japanese design techniques are follows. First, the characteristics of residential site development can be expressed as "eco-friendly" and "public order". The patterns of spatial use also focuses on living environment improvement. Second, variety replaces unity in internal mobility plans. For example the width of street, size of park are not same in a site boundary. Third, to avoid street parking and commodity exhibition, commercial buildings are set-back and public parking lot is constructed. Fourth, fences of private house are made of trees rather than bricks. It connects green environment between internal and external space of houses.nal space of houses.

  • This study was conducted to determine clutch size and habitat usage of Kentish plovers (Charadrius alexandrinus) breeding on Sinja-do lslet in the Nakdong Estuary from 22 April to 12 July in 1995 and from 21 April to 20 June in 1996. The Kentish plover preferred grasslands and damp sands to dry dunes as nesting sites. The difference in hatching success among these microhabitats was attributed to high tides, which washed away many nests on damp sands, and strong winds, which frequently shifted the sand to bury eggs on dry dunes. The main mortality factor in grasslands was predation by magpies Pica pica. Each clutch contained one to four eggs, with a mode of three eggs. Hatching success was highest in two-egg clutches and lowest in one- and four-egg clutches. The mean interval for egg laying was 1.8 days between the first and second eggs and 2.1 days between the second and third eggs. The average incubation period was about 24.2 days.

  • Chondroblastoma is a rare benign bone tumor most frequently found in the epiphyseal region of long bones. The most common locations are the knee and proximal humerus,but the rib is an unusual site. Second decade is the most common age group. The ossification centers for the rib appear in the second fetal month and ossify in a caudal-to-cranial direction. There are also epiphyseal centers at the head and tubercle of the rib that appear at puberty and ossify in the third decade. The epiphyseal plates of the head and tubercle may be the site of origin of the posterior chondroblastomas; the anterior lesions may arise from the costochondral junction. The histologic features consist of polygonal chodroblast, small foci of chondroid production, osteoclast-like giant cell, and are diagnostic of chondroblastoma.We experienced a case of the chondroblastoma arising from the rib, and its clinical and histologic features are discussed.

  • Paravertebral anesthesia for operation of abdominal wall in Korean cattle were effectively accomplished with the following technique. Any problems in surgical procedure were not observed under the block of ventral branches of the last thoracic nerve and the first and second lumbar nerves with the administration of preanesthetic. The site of injection for blocking of ventral branches of the thirteenth thoracic nerve were approximately 5cm lateral to the midline from the posterior edge of spinous process of the 13th thoracic vertebra and about 10ml of local anesthetic was injected immediately anterior to the transverse process of the first lumbar vertebra through thin site. The block of ventral branches of the first and second lumbar nerves were obtained by injecting 10ml of local anesthetic immediately below the posterior edge of transverse process of the 2nd and 4th lumbar vertebra, respectively.

  • Objective: To observe local and systemic toxicity after sustained-release 5-fluorouracil (5-Fu) implantation in canine peritoneum and para-aortic abdominalis and the changes of drug concentration in the local implanted tissue with time. Methods: 300 mg sustained-release 5-Fu was implanted into canine peritoneum and para-aorta abdominalis. Samples were taken 3, 5, 7 and 10 days after implantation for assessment of changes and systemic reactions. High performance liquid chromatography was applied to detect the drug concentrations of peritoneal tissue at different distances from the implanted site, lymphatic tissue of para-aortic abdominalis, peripheral blood and portal venous blood. Results: 10 days after implantation, the drug concentrations in the peritoneum, lymphatic tissue and portal vein remained relatively high within 5 cm of the implanted site. There appeared inflammatory reaction in the local implanted tissue, but no visible pathological changes such as cell degeneration and necrosis, and systemic reaction like anorexia, nausea, vomiting and fever. Conclusions: Sustained-release 5-Fu implantation in canine peritoneum and para-aortic abdominalis can maintain a relatively high tumour-inhibiting concentration for a longer time in the local implanted area and portal vein, and has mild local and systemic reactions. Besides, it is safe and effective to prevent or treat recurrence of gastrointestinal tumours and liver metastasis.

  • The purpose of this study was to identify and to compare the internet service factors affecting shopping satisfaction and intention to return between total shopping sites and fashion specialty sites. Data were obtained from 208 men and women aged between 20-40 who used internet. Factor analysis, Multiple regression, chi square test and F test were applied. The results were as follows. First, there were some demographic differences between two site shoppers. Young, low-income, student consumers were more likely to visit fashion specialty site than older, high-income, non students were. Second, consumer satisfaction and revisit to the total shopping sites were influenced by site composition, purchasing convenience, and after-purchase service. For the fashion specialty sites, consumer satisfaction was affected by site composition and after-purchase service while consumer intention to return was only by site composition. Thus, big sized total shopping sites should provide all kinds of online services to satisfy consumers. Small sized, fashion specially sites had better concentrate on site design or fashionable, creative product merchandising to get a competitive edge for young customers.

  • Cytochrome c peroxidase (CcP) is a yeast mitochondrial enzyme which catalyzes the reduction of hydrogen peroxide to water using two equivalents of ferrocytochrome c. The CcP/cytochrome c system has many features which make it a very useful model for detailed investigation of heme protein structure/function relationships including activation of hydrogen peroxide, protein-protein interactions, and long-range electron transfer. Both CcP and cytochrome c are single heme, single subunit proteins of modest size. High-resolution crystallographic structures of both proteins, of one-to-one complexes of the two proteins, and a number of active-site mutants are available. Site-directed mutagenesis studies indicate that the distal histidine in CcP is primarily responsible for rapid utilization of hydrogen peroxide implying significantly different properties of the distal histidine in the peroxidases compared to the globins. CcP and cytochrome c bind to form a dynamic one-to-one complex. The binding is largely electrostatic in nature with a small, unfavorable enthalpy of binding and a large positive entropy change upon complex formation. The cytochrome c-binding site on CcP has been mapped in solution by measuring the binding affinities between cytochrome c and a number of CcP surface mutations. The binding site for cytochrome c in solution is consistent with the crystallographic structure of the one-to-one complex. Evidence for the involvement of a second, low-affinity cytochrome c-binding site on CcP in long-range electron transfer between the two proteins is reviewed.

  • In Korea, the apartment buildings have been constructed recently in large quantities to provide housing due to the gravitation of population towards large cities. However, because of this trend toward high-rise apartment, a number of problems are occurred such as the deterioration of comfort in the dwelling environment and the lack of solar access right in apartment buildings. In the building law, the sunshine hour and the minimal separated distance between apartment buildings as regulated as the criteria for the site planning. Most of site planners, however, designed the apartment site only following minimum separated distance. As a result, the problem of sunshine hours lack is caused and legal dispute concerning solar access right is also arisen. The purpose of this study is to improve solar access right regulation and to help site design of apartment planning. Accordingly, we execute empirical analysis based on computer simulation in order to find suitable separated distance between typically designed apartment buildings. First, we estimated sunshine hours according to independent building orientation, height, and length. Second, we calculated sunshine hours in various case of apartment arrangement; parallel type, courtyard type, tower type and etc. with various separated distance.

  • Seowon(書院) was an institute for education and sacrificial rite, established privately in rural villages throughout the middle period of the Chosun dynasty(1392-1910), where scholars researched classic studies, cultivated personal characters in accordance with the Neo-Confucianism, nurtured young disciples, and performed rites at a secluded shrine where spiritual tablets of honorees were housed. This study examines the architectural characteristics of Pilamseowon(筆巖書院) in Chans'seong, Chollanamdo Province, Korea. Through the study, the architectural characteristics of Pilamseowon were found as follows: First, Pilamseowon moved twice since it had been established. Second, through the moving, the area of Pilamseowon was expanded and buildings were added. Third, some buildings of Pilamseowon reflect the previous condition of the seowon site. Take Hwakyeonroo(廓然樓) as an example, which is the main entrance pavilion of Pilamseowon. Pavilion is an appropriate type of building in sloped site. Before Hwakyeonroo was moved to the present site, it was located on sloped site, where Hwakyeonroo accordingly took the pavilion type of building. Present site condition of Pilamseowon is plane, nonetheless, Hwakyeonroo has the pavilion type of building, which reflects the previous condition of the building site. Forth, Pilamseowon consists of six spatial domains and each domain has its own entrance gate to outer area.
