유비쿼터스 환경에서 정확한 데이터를 얻기 위해, 무선 센서 네트워크의 신뢰성은 필수적이다. 이것을 위해, 롤백 기술을 통한 자가 치유는 신뢰성 향상에 도움을 준다. 하지만, 로컬 시스템만을 고려한 기존 롤백 기술은 무선 센서 네트워크에서 자칫 전체 시스템 차원의 결함을 발생시킨다. 따라서, 롤백 기술을 무선 네트워크 차원으로 지원하기 위해 체크포인트 프로토콜이 제시되었다. 하지만, 무선 센서 네트워크가 가지고 있는 특유의 제한 조건 때문에 각각의 프로토콜들은 메모리, 성능, 그리고 전력 소모 효율에 있어서 상충관계가 존재한다. 따라서, 본 논문에서는 주소 기록 기반 프로토콜(address log based protocol, ALBP)이라 불리는 새로운 프로토콜을 제시한다. 이 기법은 비동기 방식을 지원하는 플랫폼 기반의 프로토콜로, 무선 센서 네트워크에서 중요한 고려사항인 전력 소모량, 메모리 사용량, 그리고 마감시간을 맞추기 위한 빠른 응답시간을 만족시킬 수 있다.

For last decades, the interests and efforts to enhance healthcare facility users' experience is focused on improving facility environments for healing (Delvin, 2003) and servicescapes in order to meet the users' needs (Becker, 2008; Seunghee, 2011). In the emerging experience economy, customer want experiences and they're willing to pay for the experiences and memories not goods. (Pine, J. & Gillmore, J., 1999). It is important to identify what supports customer experiences and how they perceive the experiences in healthcare environments and it will provide important information for healthcare planners, managers, architects, and interior designers. This study examines the service user experience design elements from a User Experiences design perspective. It focuses on healthcare facilities as user experience elements and build up a conceptual framework that outlines service user experience design elements in healthcare facilities. Literature review and case studies were conducted to build the service user experience design elements according to affordance theory. Findings from this study shows that service user experience design elements were introduced and newly developed which can be categorized into three factors; 1) Functional experiences in the physical environments (safety, accessibility, self-directiveness), 2) emotional expression and cognitive experiences (identifiability/clarity, natural features/pleasant environment, aesthetic elements/playful space, media richness), 3) social relational experiences(closeness, privacy, communication with staff, integrated system). These service user experience design elements will help healthcare facility designers to understand what customer experiences, how they increase the satisfaction, and how they improve facilities for modeling the industry's best practices.

Purpose: Surgical excision of the subcutaneous tissues, with or without skin excision in the axillary hair-bearing area, has been the treatment of choice in treating osmidrosis for several decades. However, long periods of postoperative immobilization of a shoulder joint, partial necrosis of skin flaps or the possibility of hematoma and scars have occurred frequently. So we used $XPS^{(R)}$ microresector(Shaver) in procedure which requires removal of soft tissue for comparing results between surgical excision and the laters. Methods: From January 2007 to February 2008, a total of 20 patients(8 male and 12 female) underwent $XPS^{(R)}$ microresector(Shaver) assisted aspiration for treating osmidrosis. The mean age of the subjects was 21.9, and we tried to analyze some advantages of $XPS^{(R)}$ microresector(Shaver). Results: The average operation time was 61.6 minutes. This results can show that the patients who received $XPS^{(R)}$ microresector(Shaver) assisted aspiration can accomplish better outcomes than any other procedures in terms of operation time at least. Moreover, no significant postoperative complications occurred in our studies. Subjects have been followed up from 2 months to 1 year and among these patients, no one suffered from critical complications. Conclusion: In brief, $XPS^{(R)}$ microresector(Shaver) is able to shorten the time of operation and simplify the procedures relatively and this device has more superiorities in wound healing by maintaining of vascularized dermal skin flaps. It means that $XPS^{(R)}$ microresector (Shaver) can prevent flap necrosis, axillary hair loss and minimalize scarring and bleeding. Thus, we expect that these advantages can lead to better patient's comfort and self-confidence than several previous procedures.

Microbially induced calcium carbonate precipitation (CCP) is a long-standing but re-emerging environmental engineering process for production of self-healing concrete, bioremediation, and long-term storage of CO₂. CCP-capable bacteria, two Bacillus strains (JH3 and JH7) and one Sporosarcina strain (HYO08), were isolated from two samples of concrete and characterized phylogenetically. Calcium carbonate crystals precipitated by the three strains were morphologically distinct according to field emission scanning electron microscopy. Energy dispersive X-ray spectrometry mapping confirmed biomineralization via extracellular calcium carbonate production. The three strains differed in their physiological characteristics: growth at alkali pH and high NaCl concentrations, and urease activity. Sporosarcina sp. HYO08 and Bacillus sp. JH7 were more alkali- and halotolerant, respectively. Analysis of the community from the same concrete samples using barcoded pyrosequencing revealed that the relative abundance of Bacillus and Sporosarcina species was low, which indicated low culturability of other dominant bacteria. This study suggests that calcium carbonate crystals with different properties can be produced by various CCP-capable strains, and other novel isolates await discovery.

This study was carried out to introduce the Foot reflexo-massage (FRM) as a method of nursing practice based on the health promotion of occupational health. Literature reviews were done to achieve study aims from October in 1999 to August in 2000. The results were as follow ; 1. Theory of the FRM was mainly developed from the reflexology based on function and role of foot. 2. The FRM is focused on the appropriate reflexology of foot with pressures of light-moderate-light or light-strong-light scaled strength for 15 minutes at each feet. The massage should begin with the foot area where it is assumed as a was, of internal to external and upper to lower side. It also should start from left to light side of the feet. 3. The FRM is an alternative therapy increasingly demanded as an self applying method between eastern and western due to the benefit of natural healing power with no side effects. 4. The FRM can be an nursing intervention for health promotion of employees through supportive and educative nursing system in occupational health service. As a conclusion of the study, it suggested that the FRM can be recommended as a nursing intervention to promote health of employees and to prevent disease related to work.

지난 수년간 콘크리트의 염소이온 침투와 유관되어 실험방법론 및 해석적 모델 기법의 개발에 많은 발전이 있어왔다. 그러나 실제 콘크리트 구조물에는 다소의 균열이 존재하며 이는 장기 내구성에 큰 영향을 줄 수 있음에도 불구하고, 대부분의 연구들은 비균열의 콘크리트를 대상으로 연구되어 온 문제점이 있었으며 균열이 존재하는 콘크리트의 염소이온 침투에 대한 연구는 매우 드문 실정이다. 본 연구의 저자는 단기 촉진실험에 의하여 균열이 염소이온에 미치는 영향을 살펴보았다. 그러나 신뢰성있는 결과를 얻기 위해서는 장기 실험을 통한 고찰이 필요하다. 본 연구의 목적은 장기 및 단기 실험결과를 비교하였는데, 자기치료 효과에 의하여 균열이 시간이 경과함에 따라 감소하는 뚜렷한 경향을 확인할 수 있었다.이러한 경향은 균열 폭이 클수록 자기치료에 의한 균열감소 효과가 더욱 뚜렷하였다.

The "WuQinXi" exercise, one of the medical Qi-gongs, is an exercise maximizing human's self healing power and has been confirmed to be effective significantly at several modern researches. There are many exercise therapies in western medcine, such as Willams's flexion exercise, Mckenzie's extension exercise, vertebral stabilization exercise and so on. However, there isn't a special exercise therapy which can be applied for medical practice in oriental medicine. So we selected 24 motions which are related with lumbar movements from 3 type "WuQinXi" exercises ; 20 mode, 30 mode, and 40 mode. And then, we classified them according to lumbar movements as flexion, extention, lateral bending and rotation, and also functions as stabilization and rubbing. Next, with these classifications, we assorted them by kinds of lumbar spinal disease as HIVD(herniation of intervertebral disc), spinal stenosis, spondylolysis and spondylolisthesis, facet joint syndrome, compression fracture and spondylosis. We expect that "WuQinXi" exercise be a exercise therapy for lumbar spinal disease at an oriental medical clinic in this way. Oriental medical doctors will be able to teach easily patients "WuQinXi" exercise's motions at clinic, depending on kinds of lumbar spinal disease each patient suffers from. We plan to study the effect of "WuQinXi" exercise by comparing patients who do the "WuQinXi" exercise with the patients who do the western medical exercise therapy.

A five-month-old toy poodle was referred for treatment of bilateral mandibular fractures. Preoperative skull and dental radiographs showed rostral mandibular fractures and permanent teeth that had not yet erupted. In addition to providing stability for the healing of fractures, it is very important to focus on restoring normal occlusion. The mandibular fractures were repaired using interdental wiring in a dentate area where the deciduous canines and fourth premolars were stable and could be used to anchor the interdental fixation. In the absence of an erupted permanent mandibular first molar, the modified Risdon wiring was performed using the deciduous mandibular fourth premolars as anchor teeth. An intraoral splint was placed on the mandibular teeth using self-curing composite resin. Five months after surgery, the patient had experienced no complications, and the permanent teeth had erupted normally. In this case, which involves a small-breed puppy with deciduous dentition, treatment with a wire-reinforced interdental splint using intact deciduous fourth premolar teeth as anchor teeth can be considered as a suitable method for rostral mandibular fracture restoration.
