Calcaneus is largest tarsal bone and the fracture of calcaneus is most common tarsal fractures. Calcaneal fractures are divided into extra-articular and intra-articular fractures. Intra-articular calcaneal fractures could be classified as tongue type and joint depression type using simple lateral radiograph (Essex-Lopresti classification), but Sanders suggested new classification according to involving the posterior facet of calcaneus using computed tomography. The involvement of posterior facet was revealed as more complicated than Essex-Lopresti classification. The principle purpose of treatment of calcaneal fractures are restoration of calcaneal height (B$\ddot{o}$hler angle), width, axis, anatomical reduction of joint and restoration of function through the stable fixation. Good visualization of joint and anatomical reduction could be achieved by extended lateral approach. But, skin problem could be occurred after of extended lateral approach.

This study investigates the antecedents of knowledge sharing behavior focusing on the individual level factors in an assumption that the behavior is initiated from the individual level decisions. A hypothesis that the relation between personality trait and behavior is mediated by the social-cognitive constructs contained in the Theory of Planned Behavior(TPB) is tested. For the study, we suggest a TPB extended model that extends original TPB model by including conscientiousness facet of FFM(Five Factor Model). This study uses a cross-sectional design. Data were collected from a self-reported survey on 197 nurses in a tertiary hospital. The results showes a significant positive relationship between the conscientiousness facet of FFM and knowledge sharing behavior. In the TPB extended model, the conscientiousness facet has significant direct effects on all the constructs of original TPB model. Of the TPB exogenous constructs, the social norm construct alone has a significant effect on intention and the perceived behavioral has a direct significant effect on the knowledge sharing behavior. These results confirm the importance of conscientiousness in predicting knowledge sharing behavior and clarify the characteristics of knowledge sharing behavior as a contextual, job oriented behavior in a workplace. We conclude that personality trait as conceptualized in the FFM needs to be integrated into TPB model in explaining the knowledge sharing behavior. Based on these results theoretical and practical implications are discussed.

We present the results for the design ofantireflection (AR) coatings on facets of a multilayered structure waveguide device. The method, whose results agree very well with the reusults of the rigorous method in the case of a symmetric three layer structure deveice, is extended for the design of AR coatings on the facets of a multilayered structure waveguide device. the field profile in a multilayered structure waveguide necessary for the use of the extended method is obtained from the transfer matrix method. The virtual four layered structure method (VFLM) is proposed to reduce the time for the design ofAR coatings because the time for the design of AR coatings using the extended method increases as the number of layers increases. The optimum coating parameters and tolerance mapsfor two different six layered waveguide devices in Ref. [9] and [10] are obtained using the extendedmethod and the VFLM,and for the three different cases approximated as three layered waveguide devices to compare the results of each case. The results of the VFLM are similar to those of the extended methodcompared to those of the three layered structure waveguide. The main reason for the above results is that the field profile in the device calculated usingthe VFLM is similar to that calculated using the extended method compared to that for three layered structure wavegjide. We conclude that the extended method or VFLM should be used for the design of AR coatings on facets of a deice required for the facet reflectivity less than 10$^{-3}$ such as a semiconductor otical amplifier.

The objective of this study is to analyze the relationship between offline trust and use of online service focusing on Internet banking. For this purpose, we suggest an extended version of Technology Acceptance Model (TAM) that would explain use or acceptance of infer]nation technology especially in Internet based service areas. In order to connect offline trust with Internet banking use, TAM is extended by adding two variables - technical competence for security services that is one facet of trust on the bank's security technology and security risk that would influence use, perceived usefulness and perceived ease of use. Empirically our model is well proved with low significance level.

버전 제어 시스템은 급속한 환경의 변화나 개발 환경이 복잡한 프로그래밍 환경에서 사용되고 있으며, 형상 형성 (configuration thread) 정보의 제공과 이의 처리 방법은 버전 제어에서 중요한 역할을 하고 있다. DSEE에서의 시스템 모형, ClearCase의 뷰, SourceSafe의 레이블, CCC/Harvest의 패키지 등의 형상 형성도구들은 정형화된 형상 규칙을 사용자가 적용하여 필요한 버전에 대한 형상 정보를 얻고 있다. 그러나, 이들 방법에서는 정의된 형상 규칙 정보를 정확하게 알지 못하는 경우나 미리 정의되지 않은 정보에 대해서는 형상 형성 정보 제공 문제가 발생한다. 또한, 이들 정보는 세부적으로 연계된 정의되지 않은 관련 버전이나 메타 정보를 제공하지 못하는 단점을 가지고 있다. 본 논문에서는 이러한 문제를 해결하고 효율적인 형상 형성제어를 위한 시스템을 모델링하고 구현하였다. 이 시스템에서는 형상 형성 정보를 효율적으로 제공하기 위해 부울리언 검색 모델과 벡터 검색 모델을 결합한 혼합 검색 모델을 제안하였으며, 라이브러리는 확장 facet 방법을 응용하여 설계하였다.

The anatomy of the renal papilla and pelvis of the bat(Pipistrellus abramus abramus Temminck) and their ultrastructure of the epithelium has been studied by means of light, scanning and transmission electron microscopy. The bats were captured at Ondal cave located in Yangchun-Myun, Tanyang-Kun, Chungchongpuk-Do, Korea in the active(July) and hibernating(January) phases. A conical renal papilla with several papillary foramina at the apex was curved toward the ureter. At the margin of the funnel-shaped renal pelvis, the fornix extended deeply into the kidney parenchyme was formed between the outer zone of the medulla and the cortex. The epithelium of the papilla covered the inner zone of the medulla. The epithelium of the fornix medially overlayed the outer zone of the medulla, and laterally the cortex. The surface epithelium of the papilla was simple columnar in shape with the scanty organelles and the short microvilli on their luminal surface. The fornix was Jined with $1{\sim}2$ cell layered squamous epithelium. On the medial surface of the fornix, two types of the superficial epithelial cells were identified; one had numerous short microvilli and the other had the microplicae and plaques on their luminal surface. The lateral surface of the fornix lined with the epithelial cells showed microridges and plaques on the luminal surface. The epithelial cells on the medial and lateral surfaces of the fornix were similar to their internal ultrastructures. The pelvic epithelium was a typical transitional type, which was composed of a layer of basal cells, one or two layers of intermediate cells, and a layer of superficial(facet) cells. The fusiform vesicles were observed in the cytoplasm of the intermediate and facet cells. There were no noticeable morphological changes in the epithelium of the papilla, fornix and pelvis except the medial epithelium of the fornix in the hibernating cycle. The microvillar cells were more numerous in the hibernating phase than in the active phase. The morphology, of the renal papilla and fornix of bats, indicates that a functional relationship may exist between the pelvic urine and the renal parenchyme.

In Korea, the importance of keeping the see transportation facilities and well-trained maritime officers cannot be overemphasized, because of her geographical location and the national security in terms of both political and economical situations. In this paper, some points are suggested for the development of the nautical education in Korea Maritime University: (1) the strict regimental training should be kept as a vital important part of students life and its program should be designed to provide students with leadership training and experience, and to develope in the qualities of responsibilities for good citizenship and self-discipline to overcome hardwork for careers as leaders in Korea maritime industry. And therefore the dormitory and training vessel as essential parts of the educational facilities should be improved both in quality and quantity, (2) the undergraduate course should be extended to more than 5 years so that accredited baccalaureate curriculum and licensing professional education might be well conducted to meet the requirements to cope with the international competition in the facet of seafarers quality, (3) more enlarging the opportunities of incentive payments for students is required so that better qualified applicants can be admitted, (4) finally, a conjugal maritime officer service system should be put into practice in the foresseable furture so that seafarers might live normal family lives while staying at sea.

Percutaneous osteoplasty (POP) is defined as the injection of bone cement into various painful bony lesions, refractory to conventional therapy, as an extended technique of percutaneous vertebroplasty (PVP). POP can be applied to benign osteochondral lesions and malignant metastatic lesions throughout the whole skeleton, whereas PVP is restricted to the vertebral body. Common spinal metastases occur in the thoracic (70%), lumbosacral (20%), and cervical (10%) vertebrae, in order of frequency. Extraspinal metastases into the ribs, scapulae, sternum, and humeral head commonly originate from lung and breast cancers; extraspinal metastases into the pelvis and femoral head come from prostate, urinary bladder, colon, and uterine cervical cancers. Pain is aggravated in the dependent (or weight bearing) position, or during movement (or respiration). The tenderness and imaging diagnosis should match. The supposed mechanism of pain relief in POP is the augmentation of damaged bones, thermal and chemical ablation of the nociceptive nerves, and local inhibition of tumor invasion. Adjacent (facet) joint injections may be needed prior to POP (PVP). The length and thickness of the applied needle should be chosen according to the targeted bone. Bone cement is also selected by its osteoconduction, osteoinduction, and osteogenesis. Needle route should be chosen as a shortcut to reach the target bony lesions, without damage to the nerves and vessels. POP is a promising minimally invasive procedure for immediate pain relief. This review provides a technical survey for POPs in painful bony lesions.
