The purpose of this study is to identify the inpatient service quality at mental hospitals and to examine the effect of service quality on patient's overall satisfaction and customer loyalty. Data collection was done through conducting a survey of inpatients in three mental hospitals located in Chungnam, Korea using self administered questionnaire. The questionnaire included the modified version of 'service satisfaction scale for psychiatric patients' invented by Chul Kwon Kim and other members, which consists of five dimension of service quality: staff attitude, treatment quality, ward environment, access/cost and ward rule. Total 236 questionnaires were gathered and 219 were used for analysis. The data was analyzed by using version SAS9.2 and path analysis model was applied to test our hypothesis. As a result, the four factors of service (staff attitude, treatment quality, ward environment and ward rule) were extracted, which counted for 62.89% of the common variance. Moreover, Cronbach Alpha showed relatively high internal consistency of answer, all exceeding 0.6. According to the study, ward environment and treatment quality turned out to have direct influence on the patient's satisfaction. In addition, staff attitude and overall satisfaction directly influenced the customer loyalty while ward environment and ward rule indirectly had influence using overall satisfaction as a medium. In conclusion, in order to enhance the satisfaction and customer loyalty in mental hospitals, efforts in improving environmental service quality in particular is highly demanded.

This study examines academic research trends and the change of patterns by analyzing researches related to hospital management registered in Korea Citation Index(KCI) from 2010 to 2014 and offers basic information for interests and future research demands in the field of hospital management As research subjects, a total of 694 published articles were selected. It's to analyze them by dividing into research topics, methods and author's characteristics, and to present them by classifying the period into 2010-2011, 2012-2013, 3rd quarter of 2014 since there was no significant difference in the result between adjacent years. As a result, Korean Journal of Hospital Management has accounted for the highest published rate year after year. In the research topic analysis, it showed a decreasing trend in these research topics as medical marketing and patient satisfaction which became the biggest issue in 2010-2011 significantly were lower in 2014, but an increasing trend in job satisfaction, job stress, labor administration and workforce productivity. The most frequently cited keywords were hospital employees, job satisfaction, organizational commitment, job stress, turnover intention. According to the research method analysis, the survey was the most popular method for data collection. However, Interview and medical records as data sources showed a decline trend. As analysis methods, multivariate analysis of quantitative methods was most used. Finally, as a result of analyzing main author's characteristics, the ratio of the authors belonging to health administration and nursing departments of the academic world increased gradually. In the regional distribution, organizations in Seoul are most common, those in Daegu Gyeongbuk areas, foreign organizations showed a tendency to decrease. This is the first study to examine the annual trend on hospital management-related research issues among articles published in domestic journal and we found qualitative and quantitative advances in hospital management research filed.

This study aimed to clarify the multifunctional services and space composition in the process of developing a multifunctional long-term care program in small elderly care facilities in Japan. We collected data about multifunctional long-term care at small facilities from the Community Life Support Center (CLC), a Japanese non-profit corporation, and conducted an interview survey of the members of the CLC's secretariat in 2014. Furthermore, we selected 3 Japanese pioneering care facilities (known as takurosho), and conducted interview surveys and data collection to clarify in detail the space composition and process of development of multifunctional long-term care at small facilities. Four distinct results were found. First, the facilities had gradually increased non-institutional services, including visitation, overnight stays, and long-term stays, to fit the needs of users and their families. Secondly, in the 1990s, they could offer both non-institutional and institutional services at the same facility, but after the long-term care insurance system began in 2000, non-institutional long-term stay services were not allowed. Third, the facilities had built extensions or extra rooms in response to increases in multifunctional services and users. These rooms had common characteristics, with sitting rooms at the center of the facility. Lastly, the maximum number of service users at each of the 3 facilities was limited to 15, to maintain a small scale. However, as the size of facilities was increased through building extensions or remodeling, the overall amount of area available to users increased.

A home-made meju sample contaminated naturally with aflatoxins was used for isolation of fungal strains. Overall, 230 fungal isolates were obtained on dichloran rosebengal chloramphenicol (DRBC) and dichloran 18% glycerol (DG18) agar plates. Morphological characteristics and molecular analysis of a partial ${\beta}$-tubulin gene and the internal transcribed spacer (ITS) of rDNA were used for the identification of the isolates. The fungal isolates were divided into 7 genera: Aspergillus, Eurotium, Penicillium, Eupenicillium, Mucor, Lichtheimia, and Curvularia. Three strains from 56 isolates of the A. oryzae/flavus group were found to be aflatoxigenic A. flavus, by the presence of the aflatoxin biosynthesis genes and confirmatory aflatoxin production by high-performance liquid chromatography (HPLC). The predominant isolate from DRBC plates was A. oryzae (42 strains, 36.2%), whereas that from DG18 was A. candidus (61 strains, 53.5%). Out of the 230 isolates, the most common species was A. candidus (34.3%) followed by A. oryzae (22.2%), Mucor circinelloides (13.0%), P. polonicum (10.0%), A. tubingensis (4.8%), and L. ramosa (3.5%). A. flavus and E. chevalieri presented occurrence levels of 2.2%, respectively. The remaining isolates of A. unguis, P. oxalicum, Eupenicillium cinnamopurpureum, A. acidus, E. rubrum, P. chrysogenum, M. racemosus, and C. inaequalis had lower occurrence levels of < 2.0%.

ConceptNet is a common sense knowledge base which is formed in a semantic graph whose nodes represent concepts and edges show relationships between concepts. As it is difficult to make knowledge base integrity, a knowledge base often suffers from incompleteness problem. Therefore the quality of reasoning performed over such knowledge bases is sometimes unreliable. This work presents neural tensor networks which can alleviate the problem of knowledge bases incompleteness by reasoning new assertions and adding them into ConceptNet. The neural tensor networks are trained with a collection of assertions extracted from ConceptNet. The input of the networks is two concepts, and the output is the confidence score, telling how possible the connection between two concepts is under a specified relationship. The neural tensor networks can expand the usefulness of ConceptNet by increasing the degree of nodes. The accuracy of the neural tensor networks is 87.7% on testing data set. Also the neural tensor networks can predict a new assertion which does not exist in ConceptNet with an accuracy 85.01%.

Objective : This study is performed to compare older with younger groups about clinical characteristics and overall outcome of treatments for the intracranial aneurysms. Methods : We retrospectively investigated 633 patients with cerebral aneurysms who were admitted to our institute from January 2000 to May 2004. The authors divided the patients of cerebral aneurysm into two groups, one the third, fourth decades and the other eighth, ninth decades, analyzed clinical characteristics and overall outcome of treatments. Results : There were 57 patients [9.0%] under 39years old and 58 patients [9.2%] over 70. The female to male sex ratio was 0.5 : 1 in the younger group[YG] and 7.3 : 1 in the older group[OG], showing a female predominance with increasing age. In the YG, aneurysms were found in anterior communicating artery[A-com] [44.8%], middle cerebral artery [31.0%]. In the OG, aneurysm of posterior communicating artery [30.1%] was most common followed by that of A-com [26.9%]. More smokers and alcoholics were found in the YG. Older age was related to poor Hunt-Hess grade, Fisher's grade on admission, high incidence of unruptured aneurysms, and endovascular surgery. There was a higher prevalence of hypertension, intraventricular hematoma, hydrocephalus, and rebleeding in the preoperative state in the OG and postoperative complications including hydrocephalus, subdural fluid collection, and systemic complications. Overall outcome was poorer with advancing age [p=0.01]. Conclusion : The patients with aneurysms in the YG have distinct characteristics compared to those in the OG. Because of a good clinical grade on admission, a thin subarachnoid clot, and Low incidence of perioperative complications, the overall outcomes of the young patients were better than those of the old patients.

Recently, the amount of electronic scrap is rapidly increasing due to the rapid growth of the electronics industry. Among the components of electronic scrap, the printed circuit board(PCB) is an important recycling target which includes common metals, precious metals, and rare metals such as gold, silver, copper, tin, nickel and so on. In Korea, however, PCB recycling technologies are mainly commercialized by some major companies, and other process quantities are not accurately counted. According to present situation, several urban mining companies, research institutes, and universities are conducting research on recovery of valuable metals from PCBs and/or reusing them as raw materials that is different from existing commercialization process developed by major companies. In this study, we analyzed not only current status of collection/disposal process and recycling of waste PCBs in Korea but also the trend of recycling technologies in order to help resource circulation from waste PCBs become more active.

A microarray is a collection of thousands of DNAs or RNAs arranged on a substrate, and it enables one to navigate large amounts of gene expression. However, a researcher uses his designed experimental methods to focus on particular phenotypes from the available mass of data. In this paper, we used MicroRNAs(miRNAs) and Protein-Protein Interation(PPI) databases to enhance and expand meanings in microarray data. Further, the expanded data are linked with the Online Mendelian Inheritance in Man(OMIM), and International Statistical Classification of Diseases and Related Health Problems, $10^{th}$ Revision(ICD-10), in order to extract common genetic relationships between diseases. This approach, we expect, should provide new biological views.

Purpose: To provide basic data and to identify the risk of pressure ulcers among neurological patients in ICU. Method: The participants in the study were on 78 neurological patients in the ICU of 3 hospitals. Data were collected every other day from 24 hours after admission, for up to 40 days or until discharge. The total period of data collection was 3 months. The risk assessment scales used for pressure ulcer were the Cubbin & Jackson(1991) scale and the National Pressure Ulcer Advisory Panel(1989) skin assessment tool. Results: There was a significant relationship between having a pressure ulcers and weight, skin condition, mental status, respiration, hygiene and hemodynamic status compared to not having a pressure ulcer. The incidence rate of the pressure ulcer was 28.2%(n=22). Of these patients the mean number of hospitalization days until pressure ulcer development was 5.2 days. The most common pressure ulcer site was the coccyx(39.3%). Based on a cut-off point of 24, 9 patients with risk scores <24 on admission also showed risk score for development of pressure ulcers, 10 patients with pressure ulcer scores ${\geq}24$ were older, hospitalized for a longer time, had low serum albumin, low hemoglobin, diabetes mellitus and surgery. Conclusion: In order to make the Cubbin & Jackson risk assessment scales more useful, there is a need to determine the reliability of the upper cut-off point 24. The result also showed a need to assess other risk factors and for early identification of at-risk patients in order to provide preventive care from admission to discharge.
