  • Biopsy is a type of histopathological examinations, in which a physician samples cells or tissues from a patient's suspicious lesion. Such a lesion frequently resides deep inside human body, and then a percutaneous biopsy is therefore performed using a thick needle with the assistance of medical imaging such as computed tomography(CT) and magnetic resonance imaging(MRI). Recently modern robotic technology is being introduced to percutaneous biopsy in order to reduce any possible human error and hazard on physicians caused by medical imaging. After medical imaging locates the exact location of lesion, an optimization algorithm plans the path for a biopsy needle. Subsequently, a robot system moves the biopsy needle to the lesion in accurate and safe way with the control of a practitioner or automatically. In this article, we try to look into the state-of-art of percutaneous biopsy using such robotic technology. We classified percutaneous biopsy robots by mechanical characteristics and by imaging technology. Then, advantage and disadvantage of each class type are described as well as the basic description, and a few representative designs for each type are introduced. Current research issues of robotized percutaneous biopsy are subjectively selected for the readers' convenience. We emphasize the basic technology of actuator and sensors compatible with imaging technology to conclude this review.

  • The growth of information and communication technology (ICT) has led to a rapid of business paradigm shift incurred in the creation of new social/market value, changes of a value chain and elements producing a value creation, and enlargement of the scope of market competition. It leads to the change and evolution of industrial structure, requiring innovations of policy and institution. However, most studies that have focused on the effect of policy and institution on innovation are based on thick description and qualitative evidence, while paying little attention to these linkages in an empirical way. Hence this study has attempted to empirically analyze policy and institutional factors affecting innovation performance, particularly attention to ICT industry in OECD countries. The findings derived from the empirical analysis provide important implications for catch-up countries in relation to the innovations of policy and institution for effective innovation system and start-up ecosystem.

  • The Sangdong tungsten (mostly scheelite) mine is located on the southern limb of a major syncline, the Hambaeg syncline, in a thick sequence of lower Paleozoic sedimentary rocks in the mideastern part of south Korea. Productive scheelite mineralization in Sangdong area is confined to one single formation, the Myobong Slate. Four major ore beds, which have an lateral extension over than 1 km and were not heavily subjected to spatial disturbance, are developed in the Myobong Formation. The original materials of the ore-comprising horizones were probably of either calcareous or silceous sediments. The four ore beds, especially in the case of Main ore bed, display both lateral and vertical zoning. Association quartz-mica-scheelite is predominant in the central, while association hornblende-quartz-diopside-scheelite, diopside-garnet and wollastonite-garnet are developed in this order towards the periphery of the ore beds. Petrologically, two phases of thermometamorphism are recognized. The first phase is represented by the association wollastonite-garnet and diopside-garnet, while the second phase by the association hornblende-quartz-diopside-scheelite and quartz-mica-scheelite. The associations of the second phase do constitute prodctive ore. The high background value of tungsten in the area surrounding the Sangdong mine reveals that the area can be considered a geochemical zone enriched in tungsten. Studies on the trace element patterns were carried out to draw useful criteria for the purpose of future geochemical exploration in the area. The increasing trend of the ratio Rb $({\times}1000)/K_2O$ of the Myobong Slate towards the known mineralization area proved to be indicative for the presence of tungsten mineralization.

  • The purpose of this study is to understand underlying principle to form the U-type folk house in the northwestern part of Kangwha Island by viewpoint of inner residents. It is found that many factors other than climate are coincidentally affecting the shape of house; Resident's fixed thought like following geomancer' suggestion, seeking fortune, and locating house enclosed low site; Economic reason of uniting one house with two buildings and making small type by used timber from dismantled house; Centralizing life with small courtyard by reason of family type change from extended to nuclear; Influence from L or ㅁ type of upper class building at Seoul area. The method is thick description of culture with ethnographic method from cognitive anthropology: Observing the form and restoring residents' life with open-ended deep interview.

  • The polypore genus Abundisporus Ryvarden is characterized by resupinate to pileate fruitbodies with a purplish brown hymenophore, slightly thick-walled, pale yellowish and non-dextrinoid basidiospores, and causing white rot. A purple color hymenophore, an easily observable and striking character, was considered the main distinctive feature at the generic level within polypores. However, due to highly similar basidiocarp features, species identification within these purple polypores is particularly difficult. Three species of purple colored polypores have been reported in Korea (Abundisporus fuscopurpureus, A. pubertatis, and Fomitopsis rosea). Based on morphological re-examination, ecological information, and sequence analysis of the internal transcribed spacer, we showed that previous classification was incorrect and there is only one species (A. pubertatis) in Korea. We provide a detailed description of A. pubertatis in Korea, as well as a taxonomic key to distinguish wood rot fungi with a purple hymenophore.

  • A new dragonfly species, Nannophya koreana sp. nov., is described from Korea on the basis of morphology and mitochondrial cytochrome oxidase c subunit I (COI) gene sequences. Nannophya materials from Korea and other areas in Southeast Asia were compared. The new species was previously recognized in Korea as the endangered pygmy dragonfly Nannophya pygmaea Rambur, 1842, which is widely distributed in insular and peninsular Southeast Asia. However, male adults of the Nannophya population in Korea could be distinguished from other N. pygmaea populations by the presence of a thick, incomplete black stripe on the lateral synthorax that terminated at half-length (vs. continuous to wing base), light orange (vs. red) anal appendages, and 4-5 (vs. 2-3) black teeth on the ventral superior appendages. In addition, the body length of N. koreana was generally larger (1.2-1.4 times) than that of N. pygmaea, regardless of life stage. COI gene sequences from the two groups exhibited substantial genetic differences (>12%), thereby sufficiently substantiating their differentiation. The taxonomic status, distribution, and habitat of the new species are discussed.

  • Referring to John Irving's 2001 published fiction The Fourth Hand, the publisher commented, "It seems, at first, to be a comedy, perhaps a satire, almost certainly a sexual farce. Yet, in the end, it is as realistic and emotionally moving as any of Mr. Irving's previous novels." In his early six novels, John Irving shows the world suffused with grief and deception. But his novels finally turn out also as a comic and robust novel. The writer's success in achieving this thick description of the contradictory modern world is largely due to his development of the idea of the flawed hero. Despite loss, sadness and abandonment, Irving's heroes maintain classical heroic traits such as intelligence, tenderness, protectiveness, strength, bravery, sense of humor, independence, attractiveness. In this article, I tried to emphasize these graces potent in Irving's heroes as the most attractive and influential device for the writer's consistent popularity among the general public. The cinematization of his four fictions attest to audience's sympathy toward rewarding vulnerability and truthful exaggeration in the depiction of Irving's heroes. By taking full responsibility for their own fate despite having the flaws, Irving's protagonists still appeal to many readers as heroes resilient in a modern chaotic world without losing their graces.

  • This study explores the characteristics and discourse of creative work in advertising and investigates women's work experience and their problem. This will reconfirm the characteristics of advertising as creative labour. For this, it conducts in-depth interviews and analyzes them through a theoretical detour and a thick description. The study found the dominant discourse that creativity is their duty and ultimate goal. This dominant discourse makes the gendering of creative roles and representation languished. In spite of this, female creators with parenting have difficulty in reducing work ability, because conflicting identities weaken their self-regulation. This means that advertising is 'self-regulationized' labour.

  • Two new records of marine nematodes, belonging to the family Ironidae de Man, 1876, are reported based on the specimens collected from intertidal sediments from the west coast of Korea. Conilia sinensis is characterized by a relatively long body length, a well-developed buccal cavity with three claw-like teeth, the presence of a single spicule with transverse striations, the presence of rib-shaped telamons, and single precloacal supplement. Pheronous donghaiensis is distinguished from other species of the genus by a well-developed buccal cavity with four claw-like solid teeth and minute denticles, relatively short and thick spicules with the central septum, the presence of 8-9 curved tubular-shaped precloacal supplements, and a sharp pointed tail with three small tubular supplements arranged into two rows in males. In this report, we provide a taxonomic description and illustrations of two unrecorded species of the family Ironidae by differential interference contrast microscopy. This is the first taxonomic report on the species of the family Ironidae from Korea.
