Our previous study on the binding activity between Cel5H and clay minerals showed highest binding efficiency among other cellulase enzymes cloned. Here, based on previous studies, we hypothesized that the positive amino acids on the surface of Cel5H protein may play an important role in binding to clay surfaces. To examine this, protein sequences of Bacillus licheniformis Cel5H (BlCel5H) and Paenibacillus polymyxa Cel5A (PpCel5A) were analyzed and then selected amino acids were mutated. These mutated proteins were investigated for binding activity and force measurement via atomic force microscopy (AFM). A total of seven amino acids which are only present in BlCel5H but not in PpCel5A were selected for mutational studies and the positive residues which are present in both were omitted. Of the seven selected surface lysine residues, only three mutants K196A(M2), K54A(M3) and K157T(M4) showed 12%, 7% and 8% less clay mineral binding ability, respectively compared with wild-type. The probable reason why other mutants did not show altered binding efficiency might be due to relative location of amino acids on the protein surface. Meanwhile, measurement of adhesion forces on mica sheets showed a well-defined maximum at 69±19 pN for wild-type, 58±19 pN for M2, 53±19 pN for M3, and 49±19 pN for M4 proteins. Hence, our results demonstrated that relative location of surface amino acids of Cel5H protein especially positive charged amino acids are important in the process of clay mineral-protein binding interaction through electrostatic exchange of charges.

This study was conducted to investigate the degree of utilization of outsourcing in large hospitals in Korea. We also investigated the outcome and the level of satisfaction for adopting outsourcing in these hospitals. Types of work areas that were currently operated by outsourcing and were planned to adopt outsourcing in the future were identified. A total of 83 hospitals were eligible for this study, which had more than 500 beds, and were identified from the 2003 National Hospital List published by the Korean Hospital Association. A self-administered Questionnaire survey was conducted between April 25th and May 20th in 2003 with a personnel being charged of arrangement of outsourcing in each hospital. Among the 58 hospitals responding the survey(response rate=69.9%), 49 hospitals(84.5%) utilized outsourcing in at least one work field in their organizations. The largest proportion of the hospitals(85.7%) using outsourcing responded that the biggest outcome after introducing outsourcing were cost reduction(49.0%), followed by improved efficiency in operating the organization or human resources(34.7%) and the improved quality of the work(6.1%). The degree of satisfaction for outsourcing among the hospital managers(3.43) was significantly higher than that among the employees(3.l4) on a S-point Likert-type scale(p<0.05). Among the 7 work areas, the hospitals used outsourcing most frequently in facility management(housekeeping, building maintenance, hospital security and parking management), followed by non-medical profit business(funeral, convenient store, and cafeteria), logistics(provision of patient meal, in-house delivery, and purchasing), and information and computing system(hospital information system, maintenance of personal computers and printers). The work areas that the hospitals planned to adopt or expand the outsourcing in the future most frequently were facility management, non-medical profit business, logistics, and information and computing systems. In conclusion, outsourcing was highly diffused in large Korean hospitals, particularly in the work field of facility management and non-medical profit business. The satisfaction for outsourcing was not high yet in Korean hospitals.

In recent years, over-supply of hospitals has made hospital management more difficult and hospitals have introduced innovative hospital management to enhance customer satisfaction. The purpose of this study is to investigate the effect of innovativeness of hospitals on customer satisfaction by using mediating effects of hospital capacity and location strategy. The subjects of this study were selected from 120 patients and caregivers who were hospitalized in Seoul and Metropolitan area hospitals and conducted questionnaire and statistical analysis. The results of this study are as follows: Firstly, this paper shows hospital Innovativeness does not significantly affect customer satisfaction. Unlike private companies, it is urgent to develop innovativeness measuring tools that are unique to hospitals differentiated from those of general companies. Secondly, although the impact of Innovativeness on hospital internal competency and location strategy was similar, location strategy(${\beta}=0.357$) had a greater impact on customer satisfaction than internal competency(${\beta}=0.283$). This suggests that the medical institution should take precedence over the detailed preparations based on its location marketability, traffic infrastructure, building sales and medical concentration from the time of its opening. Thirdly, this paper confirms through empirical analysis that the relationship between hospital Innovativeness and customer satisfaction is completely mediated by internal capacity and location strategy. The hospital's Innovativeness is affecting customer satisfaction by enhancing the hospital's internal competencies and inducing an active attitude toward establishing a location strategy.

Epidermal growth factor receptor (EGFR) is one of the targeted molecular markers in many cancers including lung malignancies. Gefitinib and erlotinib are two available therapeutics that act as specific inhibitors of tyrosine kinase (TK) domains. We performed a case-control study with formalin-fixed paraffin-embedded tissue blocks (FFPE) from tissue biopsies of 167 non-small cell lung carcinoma (NSCLC) patients and 167 healthy controls. The tissue biopsies were studied for mutations in exons 18-21 of the EGFR gene. This study was performed using PCR followed by DNA sequencing. We identified 63 mutations in 33 men and 30 women. Mutations were detected in exon 19 (delE746-A750, delE746-T751, delL747-E749, delL747-P753, delL747-T751) in 32 patients, exon 20 (S786I, T790M) in 16, and exon 21 (L858R) in 15. No mutations were observed in exon 18. The 63 patients with EFGR mutations were considered for upfront therapy with oral tyrosine kinase inhibitor (TKI) drugs and have responded well to therapy over the last 15 months. The control patients had no mutations in any of the exons studied. The advent of EGFR TKI therapy has provided a powerful new treatment modality for patients diagnosed with NSCLC. The study emphasizes the frequency of EGFR mutations in NSCLC patients and its role as an important predictive marker for response to oral TKI in the south Indian population.

This study is aimed to investigate the relationship among safety accident and perception of patient safety culture, to provide the basic data for building the patient safety culture of hospital nurses. The self-administered questionnaires were given to 129 nurses employed in hospital during the period from November 10th to 15th, 2011. The safety accident occurrence of patient was statistically significant difference according to safety education of nurse and job satisfaction of nurses. As a results, nurses' perception to the patient safety culture of hospital shows on the average score($3.46{\pm}0.3$). Among three categories, patient safety culture in a ward, and patient safety culture within hospital and safety awareness in a ward show respectively on the average score $3.59{\pm}0.3$, $3.41{\pm}0.5$, $3.41{\pm}0.4$. The score of level of patient safety culture of hospital nurses was statistically significant difference according to marital status, safety education, occupational satisfaction and health status. In correlation among safety accident occurrence of patient and safety education of nurse, patient safety culture in a ward, patient safety culture within hospital and safety awareness in a ward showed positive relationship. The results of this study indicate that education program are needed to prevent safety accident occurrence of patient, and to build the patient safety culture of hospital nurses, and to increase the safety education and occupational satisfaction, and to improve the nurses' health status.

Window and shading designs have a great influence on energy consumption and daylighting in buildings. As far as energy is concerned, small window area is advantageous. But it is not good to the patient healing in hospital. So it is important to find out the optimum window shape which is favorable for both energy consumption and patient healing. In this study, annual energy consumption and daylight illumination levels were analyzed according to the window shapes and shading devices for a multi-beded patient room in hospitals. The simulations were conducted for 19 different cases by COMFEN 4.0 computer simulation program. The results of this paper are as follows. First, window to wall area ratio and shading devices have great influences on annual energy consumption. But it is a problem in that they decrease significantly daylight level in bed room. Second, considering the same energy consumption, reducing the width of window rather than the hight of window is desirable for the secure of daylight level. Third, increase of the number of horizontal shade is not desirable in south face of the building for the energy consumption and daylight level. Fourth, sun shade is not necessary in north face of the building for the energy consumption and daylight level.

This study analyzed some of nursing homes in various domestic and foreign regions in order to find solutions to reduce suicidal incidents from the loneliness. To analyze community space of nursing homes, elderly community is analyzed into three categories based on their characteristics (morphological characteristics, Social characteristics, Environmental characteristics). With those three characteristics above, architectural spaces are analyzed the relation with them. Elderly nursing homes are divided with living, nursing, management, and public spaces. The space of elderly nursing homes (classification of function)-elderly community (classification of elderly characteristics) is approached in an architectural way related to the space of elderly nursing homes and elderly characteristics. Through some case studies, specific space relation of elderly nursing homes and elderly community is analyzed. Also, with the building analysis for summary, plans, wards(hospital rooms), cafeteria, program rooms and alley, some of general information and elderly community space is understood. In this study, there will be an analysis of relation of elderly community(morphological, social, environmental characteristics) which is separated into some spaces of elderly nursing homes(living, nursing, public spaces and facilities) written above. Furthermore, if people can recognize the importance of community space for elderly facilities, there will be a new guide line for that which can have a play on catalyst.

The objective of correction is to let criminals receive education, be reformed and get vocational training during prison term by being separated from society and live as sound citizens after being released from prison. The facilities that execute such mission are referred to as corrective institution, and in Korea, some 47,000 persons are accommodated at 50 locations. Corrective facilities are facilities existing to separate and accommodate criminals safely, and return them to society after eliminating criminal nature from the convicts during the accommodation period. But corrective facilities in Korea representing the characteristics of corrective facilities vividly focusing on security. Therefore, while present pursuit of corrective facilities is to seek for reformation of criminals rather than separation of them from society, existing prison buildings are not appropriate facilitated at the moment. This study has the purpose to planning of indoor environment of corrective facility ward building as healing environment. Specifically, this study is contributing to propose a model of criminals healing environment equivalent to hospital facility to raise the effect of healing the criminal nature of criminals and cut the period of restoring them by applying healing environment elements and return the criminals to the society as successfully reformed social member.

During the administration of a construction project, various types of participants are engaged in the project. From the design phase to the maintenance phase, these participants may confront many risks. To avoid these risks, participants should utilize an insurance company or a bond company. The types of risks and liability that a construction manager may face are listed in the construction law or contract. But there are some arguments related to risk transferring and the content of risks. For this reason, construction managers must carefully consider any possible risks in the contract and the construction law. Therefore, for construction managers to deal with risks appropriately, the introduction of a legal requirement to carry professional liability insurance, a defined compensation range for damages, a method of guarantee in the event of defects, a defined compensation claim period for damage, and a method of damage claim were suggested in this study.
