Objectives : The rapidly changing consumer-centric and customer-oriented nature of the medical environment results in significant cognitive load. We aimed to clarify the situation of emotional labor and job stress among hospital employees and seek policies and hospital management for employees' emotions. Methods : The study was conducted through a questionnaire about emotional labor and job stress among 554 individuals working in Seoul, in 9 national, public, and private hospitals. Results : The results of the emotional labor and job stress questionnaire showed statistically significant differences in surface behavior and job stress; both had higher values in employees from the private hospitals than employees from public hospitals. Conclusions : This study found that the stress of emotional labor is a serious problem in government medical institutions. In addition, these institutions need to provide internal customer satisfaction through the hospital ombudsman and harmonize work and healing programs by including plans for improvement.

오늘날 분산 컴퓨팅 환경에서 운용되는 시스템이 증가됨에 따라 시스템의 관리작업은 고수준의 자동화를 요구하고 있다. 이에 따라 시스템 관리방식은 전통적인 관리자 중심에서 시스템 스스로가 자신의 문제를 인식하고 상황을 분석하여 해결하는 자율 컴퓨팅 방식으로 변화하고 있으며, 현재 이에 대한 연구가 많은 연구기관에서 다양한 방법으로 이루어 지고 있다. 그러나 이러한 대부분의 연구에서 자율 컴퓨팅의 한 요소인 자가 치유는 문제가 발생한 이후의 치유에 주로 초점이 맞추어져 있다. 이러한 문제를 해결하기 위해서는 시스템 스스로가 동작환경을 인식하고 에러의 발생을 예측하기 위한 예측 모델을 필요로 하게 된다. 따라서, 본 논문에서는 자율 컴퓨팅환경에서 자가 치유를 지원하는 4 가지 예측 모델 설계 방법을 제안하며, 본 예측 모델을 ID3 알고리즘, 퍼지추론, 퍼지뉴럴네트워크 그리고 베이지안 네트워크가 각 시스템 상황에 맞추어 적절하게 사용되는 하이브리드 방식이며, 이를 통해 보다 정확하고, 신속한 에러 예측이 가능해진다. 우리는 제안 모델을 평가하기 위해 본 예측 모델을 자가 치유 시스템에 적용하여 기존 연구와 예측 효율을 비교하였으며, 그 결과를 통해 제안 모델의 유효성을 증명하였다.

Caring is being rediscovered as a central and unifying concept of the nursing. Traditionally, nursing profession has emphasized spirit and activities of caring. But there is little efforts to study the caring phenomena scientifically and systematically in nursing, and then the concept of caring is still remained unclear and ambiguous. Changes of social, and health care environment are threatening the philosophy and practice of caring, so it is urgent to identify caring more scientifically and to rediscover the nature of nursing discipline. Knowledge of the caring is essential component for the development of nursing as a science and a profession. The first thing to study a concept is thought to be the analysis of the concept. So in this study, concept analysis of caring was performed to clarify the concept of caring as a basis for the study of caring afterward. The approach used for the concept analysis of caring was the approach presented by Walker and Avant. The defining(or critical) attributes of caring identified in this study were (1) a series of activities for helping others, (2) concern and devotion. (3) interpersonal relationship, and (4) scientific and systematic process. The identified antecedents of caring were (1) awareness of other's needs for help, and (2) moral and cognitive motivation for helping others. The identified consequences of caring were (1) healing, (2) satisfaction, and (3) growth. And the consequences of caring were revealed to both of the care giver and the care receiver. The empirical referents of caring could be the behaviors of interpersonal relationship through scientific and systematic process with concern and devotion for others.

TIn the study of Yangseng(養生) and Relaxation therapy, the results were as follows : According to the traditonal oriental medical theory, Oriental medicine focused on Yangseng(養生). Especially vital-energy is able to resist the disease and adapt to the environment and assist the healing of the body. Relaxation theraphy is a kind of Qigong. And it is not only breathe, but also accumulate the vital energy in the body, Which is also called "genuine qi(眞氣)" or "internal qi(內氣)." The therapy is based on controlling of Sprit(神), Breathing(呼吸), Mind(心). And it is in harmony with Qi-circulation(氣-循環), so smoothing the circulation of meridians, strengthened Essential-material(精), Qi(氣), Sprit(神). The Relaxation theraphy made the body and mind relaxed, and it is helpful of preventation of disease and mental health. And it treats neurosis, somatoform disease, it uses main or helpful therapy of various disease, elevates health mental concentration. And it is more effective by application of music, aroma, taping, psycho-therapy.

Among the countless elements for healing environment in healthcare facility, 'privacy' has been rather neglected in general hospital designs in Korea. The fact may be due either to present situation of excessively crowded patients or to cultural origin which more stresses on the mass than on individuals. However, as patient amenity has increasingly become important, privacy should be viewed as one of the key elements in the general hospital design, in order to improve the quality of patient service as well as to compete with other hospitals. Also it is very important that those methods for privacy improvement should be not only theoretically correct but also practical enough to be compatible with medical efficiency, space availability or construction cost within a particular hospital. The purpose of this case study is to present an actual examples to improve patients' privacy adopted in the schematic design of the Seoul Asan Hospital renovation project, along with comparisons with other hospital cases.

Objective of the research is to demonstrate solar thermal space and ground heating system which is integrated to a green-house culture facility for reducing healing cost, Increasing the value of product by environment control, and developing advanced culture technology by deploying solar thermal system. Field test for the demonstration was carried out in horticulture complex In Jeju Island. Medium scale solar hot water system was installed in a ground heating culture facility. Reliability and economic aspect of the system which was operated complementary with thermal storage and solar hot water generation were analyzed by investigating collector efficiency, operation performance, and control features. Short term day test on element performance and Long term test of the whole system were carried out. Optimum operating condition and its characteristics were closely Investigated by changing the control condition based on the temperature difference which Is the most important operating parameter For establishing more reliable and optimal design data regarding system scale and operation condition, continuous operation and monitoring on the system need to be further carried out. However, It is expected that, in high-insolation areas where large-scale ground storage is adaptable, solar system demonstrated in the research could be economically competitive and promisingly disseminate over various application areas.

The demands of nursing home for the dementia are rapidly increasing. However, there are no enough nursing homes and design guidelines for it. This study was intended to examine the needs of the staff for the nursing home design and suggest the design guidelines of the Korean nursing home for the dementia. The subjects were 15 nurses and 18 care givers who worked in D hospital for the elderly with dementia in Busan. Data were collected by the self-administered questionnaire. The findings were as follows; First, the most important design element in nursing home for the dementia which the staff mentioned was 'healing environment' and then 'function' and 'maintenance' Second, the care-givers were more satisfied with their facility design than the nurses. Third, the staff pointed out that 'the relation between individual room and nursing station', namely, short distance between them, and 'enough wandering space' had to be considered at first in design process of nursing home with dementia. Also, the comfort and intimate interior mood, fresh air and sunlight were also pointed out as the important elements in nursing home design for the dementia.

Networking together hundreds or thousands of cheap sensor nodes allows users to accurately monitor a remote environment by intelligently combining the data from the individual nodes. As sensor nodes are typically battery operated, it is important to efficiently use the limited energy of the nodes to extend the lifetime of the wireless sensor network (WSN). One of the fundamental issues in WSNs is the coverage problem. In this paper, the border coverage problem in WSNs is rigorously analyzed. Most existing results related to the coverage problem in wireless sensor networks focused on planar networks; however, three dimensional (3D) modeling of the sensor network would reflect more accurately real-life situations. Unlike previous works in this area, we provide distributed algorithms that allow the selection and activation of an optimal border cover for both 2D and 3D regions of interest. We also provide self-healing algorithms as an optimization to our border coverage algorithms which allow the sensor network to adaptively reconfigure and repair itself in order to improve its own performance. Border coverage is crucial for optimizing sensor placement for intrusion detection and a number of other practical applications.

Calcite forming bacteria (CFB) have been received increasing attention as a novel and environmental friendly strategy for the healing of concrete crack. Among the CFB, spore forming bacteria were proposed to overcome concrete condition (high pH, hydration heat, deicer). In this study, Lysinibaclillus sphaericus WJ-8 (WJ-8) isolated from concrete pavement was characterized. The WJ-8 was able to precipitate calcite at 10 mg/mL. When observed by scanning electron microscopy, WJ-8 showed spore formation and maximum spore yield was approximately 97.9%. Also response of spores against various environment stresses was examined. Approximately 83~97% of spores maintained their survivability at each three conditions ($60^{\circ}C$, 3 M NaCl and pH 12).

The advent of free bone flaps has made successful replacement of extensive areas of bone loss in the upper and lower extremities. The microvascular free bone flaps have faster healing without bony absorption or atrophy and can heal in the hostile environment of scarred bed or infection. Since the fibula free flap introduced by Taylor and colleague in 1975, it has been used extensively for skeletal reconstruction of extremities. In 1988, the folded vascularized fibula free flap was first described as a technique to reconstruct significant long bone defect of upper and lower extremities. During the same time, the fibular free flap has evolved to become most preferred choice of mandibular reconstruction. Up to present day, few reports have been made on the fibular free flap used for reconstruction of injured hand containing metacarpal bone and soft tissue defect. We present here our new and unique experiences with vascularized fibular osteocutaneous free flap as useful and satisfactory one for reconstruction of hand with composite defects.
