Objectives : The aim of this study was to analyze the influence of foreign and institutional investors in the pharmaceutical industry on R&D investments. Methods : The empirical analysis was done for the years 2009 to 2013 which examined the period after the influence of the financial crisis. Financial statements and comments in general and internal transactions were extracted from the TS-2000 of the Korea Listed Company Association. STATA 12.0 was used as the statistical package for the panel analysis. Results : The results show that the shareholding ratio of foreigner investors turned out to have a statistically significant influence on R&D investment. No statistical significance was found in the shareholding ratio of institutional investors. Conclusions : The findings of this study, which indicate that a higher shareholding ratio of foreigner investors leads to greater R&D investment, indicate that foreign investors directly or indirectly impose pressure on a manager to make R&D investments for the long-term.

This research is to development advanced health(condition) monitoring system of superconducting motors. Development of advanced condition monitoring systems offers the prospect of improved performance, assessment, and operation, simplified design, enhanced safety, and reduced overall cost of advanced and next generation superconducting motor. For advanced and next generation superconducting motor design, the opportunity exists to develop and implement real-time and continuous monitoring systems by integrating wireless and computational technique. Generally, condition monitoring and control of temperature is essential for managing the superconducting motor components, rotor and structures. In this research, development of advanced monitoring in low temperature and high speed operating environments offers the potential to greatly improve the control of harsh environments. In conventional method, slip rings have been used to acquire data from these sensors. However, the increase of sensors leads to vibration of the rotation axis and noise signals due to kinematics contact. In this study, the wireless data acquisition technique was employed to develop more stable monitoring system adequate for high speed rotating system.

There is a increasingly growing emphasis on health promotion, disease prevention and optimum functioning for peaple including the chronically ill and disabled. According as the purpose of the nursing is the promotion of health, the value and belief of heal th within the nursing paradigm need to be defined in every culture. The paradigm components must be explored for meaning given by the aged in their traditional thought and philosophy, The problem addressed by this qualitative study was how the aged recognize value and belief of health, which contribute to the development of Korean nursing theory. Theoretical support for the study was from Leininger's cultural care theory and Korean philosophy and traditional oriented thought. Literature review refers to literature on the aged, health of the aged, and definition and meaning of general health concept. Grounded theory methodology guied the research methodology and analysis to build a substantive theory. The informants were 119 from a variety of social levels and family patterns; traditionally the aged are responsible for the health. The concentrated interviewing period was from may to june, 1995 ; the interviews were done by the researcher with two supporter and most were recorded on audio tape. Result from analysis of base datas follows; The value and belief of health that emerged from the categories and properties were the physical stability, the stability of mind, the stability of mind and body, the smoothness (harmony) of body function, the family concord, and the perfection of self. These values and beliefs of health are affected by the cosmic dual forces thought is based on the Great Absolute, family principle of confucian scholar, and Buddism. Among the values and beliefs of health, family concord is found out Korean culture peculiarities. These values and beliefs are all integrated into the idea of health. The study provided implications for nursing theory research, education, and practice change and development.

The objectives of this research are to examine the factors influencing the employees' satisfaction and to investigate that the employees' satisfaction effects the organizational commitment on seven National University's hospitals. The data for this analysis were collected by questionnaire survey. 657 usable questionnaires were returned, a 78.2%, response rate. The major statistical methods used for the analysis are factor analysis, t-test and hierarchical multiple regression. The findings suggest that four components of job satisfaction are selected: these are "task", "organizational operation system", "opportunity of development", "interpersonnel". Highly satisfied employees turn to organizational commitment such as responsibility of organization and retention. Futhermore the findings suggest that responsibility is affected by work period, task satisfaction, opportunity of development. And retention is affected by work period, role as teaching hospital, and task satisfation. This study concludes with a discussion of the managerial relevance of the findings and future research directions.

The purpose of this study was to evaluate the accuracy of a mobile wireless digital automatic blood pressure monitor for clinical use and mobile health (mHealth). In this study, a manual sphygmomanometer and a digital blood pressure monitor were tested in 100 participants in a repetitive and sequential manner to measure blood pressure. The guidelines for measurement used the Korea Food & Drug Administration protocol, which reflects international standards, such as the American National Standard Institution/Association for the Advancement of Medical Instrumentation SP 10: 1992 and the British Hypertension Society protocol. Measurements were generally consistent across observers according to the measured mean ${\pm}SD$, which ranged in $0.1{\pm}2.6mmHg$ for systolic blood pressure (SBP) and $0.5{\pm}2.2mmHg$ for diastolic blood pressure (DBP). For the device and the observer, the difference in average blood pressure (mean${\pm}$SD) was $2.3{\pm}4.7mmHg$ for SBP and $2.0{\pm}4.2mmHg$ for DBP. The SBP and DBP measured in this study showed accurate measurements that satisfied all criteria, including an average difference that did not exceed 5 mmHg and a standard deviation that did not exceed 8 mmHg. The mobile wireless digital blood pressure monitor has the potential for clinical use and managing one's own health.

Korea Aerospace Research Institute (KARI) have gained experience with Helicopter Vibration Health Monitoring (VHM) System technology with the help of UK GKN-WHL. GKN-WHL have had many years of experience with the research and development of vibration analysis techniques to improve the health monitoring of helicopter transmissions. This activity was targeted at transmission rig testing at first, but the techniques have been progressively developed where they are now used as a part of integrated Health and Usage Monitoring (HUM) systems on many types of in-service and new helicopters. The technique development process has been considerably aided by an ever expanding database of transmission monitoring experience from both the rig testing and aircraft operations. This experience covers a wide range of failure types from naturally occurring faults to crack propagation studies and covering a wide range of transmission configurations. Primarily based on accelerometer signals GKN-WHL's vibration analysis methods have also been applied to a variety of other sensor types. The transition from an experimental environment to operational VHM systems has been a lengthy process, there being a need to demonstrate technique reliability as well as effectiveness to both regulatory (Airworthiness Authority) and commercial organizations. Another important feature of this process has been the development of close relationships with a number of VHM system hardware and software suppliers. Such an experienced GKN-WHL provides various raw vibration data which was acquired from transmission ground test rig and allow KARI to develop it's own analysis program. KARI made a program and then analyzed the data to coma pre with the results of GKN-WHL. The KARI's results both time domain signals and statistical values show comparable to GKN's.

In this study, we investigated the chemical profile and effects of RW0117 (Artemisia argyi 65 .5 % ethanol extract) on gastric lesions in rats. We optimized and validated a method to obtain the chemical profile of RW0117. We then investigated the antioxidant and anti-inflammatory effects in vitro, and the protective effects on gastric lesions in vivo. The IC50 of 2,2-diphenyl-1-picrylhydrazyl free radical scavenging considering the antioxidant effects of RW0117 was 166.55 ㎍/mL, and the IC50 of nitric oxide scavenging considering the anti-inflammatory effects was 41.16 ㎍/mL. Oral administration of RW0117 at lower concentrations (25, 50, 100 mg/kg) had similar or greater effects than the daily intake conversion concentration (115mg/kg) of a health functional food (Avexol®) in the acetic acid-induced ulcer and the ethanol-induced gastric injury rat models. In addition, oral administration of RW0117 increased the expression of prostaglandin E2, which enhances the protective effect in the gastric mucosa in the ethanol-induced gastric injury rat model. These results suggest that RW0117 may have potential therapeutic uses in the protection of the gastric mucosa.
