현대는 정보화의 사회로서 첨단과학을 이용한 진료업무의 선진화사업은 진료의 서비스 향상과 경영혁신을 위해 필수적이다. 이번에 새로이 개발된 방사선종양학과 진료업무 전산화시스템은 병원내 처방전달시스템 개발과정에서 별도의 비용부담없이 부수적으로 개발된 것으로 방사선종양학과의 고유 업무뿐만 아니라 모든 외래 및 병실진료업무와 수납업무를 수행할 수 있는 편리한 프로그램이다. 이 시스템의 도입으로 방사선종양학과의 진료업무 간소화는 물론 신속 정확한 진료가 가능하여 진료서비스를 향상시켜 향후 다가올 진료 환경의 급격한 변화에 적극적으로 대처할 수 있어서 진료업무의 능률향상에 큰 도움이 되며 몇 가지의 새로운 기능을 추가시키면 학문연구의 발전과 경영개선효과도 기대할 수 있으리라 생각된다.

A photovoltaic panel is a device that, through the photovoltaic effect, converts luminous energy into electric energy. Photovoltaic generation system used infinity of solar energy, cost of fuel is needless and there in no air pollution or waste occurrence. This paper summarizes the results of these efforts by offering a photovoltaic system structure in 30[kW] large scale applications installed in Mokpo National University dormitory roof. The status of photovoltaic system components, are inter-connection and safety equipment monitoring system will be summarized as this article. This describes configuration of utility interactive photovoltaic system which generated power supply for dormitory. In this paper represent 30[kW] utility photovoltaic system examination result.

Since ISO 9001 quality system was established in 1987, many companies have adopted it for assuring the quality of their processes. Not only manufacturing companies but service industries such as hospitals, armies, educational institutes, banks are now implementing ISO 9001 quality management system. In this study, we proposed the definitions of customers, manufacturing processes, products, and quality characteristics of the ISO 9001:2000(E) quality management system in university. An implementation procedure of ISO 9001:2000(E) quality management system in university was also suggested. Furthermore, we dealt with the case study of 'C' College's ISO 9001:2000(E) quality management system and showed some of its effects.

In this paper, we propose a four 2-link robotic leg landing system that is used for leveling the bottom of the landing system, even when the quadcopter posture is changed. The case of conventional skid type landing gear has a risk when the quadcopter lands on a moving vehicle because the skid type landing gear is tilted to the landing site at this situation. To solve this problem, it is necessary to level the bottom of the landing system when the quadcopter posture is changed in the flight. Therefore, the proposed landing system used a four 2-link robotic leg with leveling method. The leveling method was derived from the method of determining a plane. The superiority of the proposed system was verified with 6-axis stewart platform and real flight experiment, and it shows feasibility of leveling method and proposed landing system.

A practical application of a supercapacitor energy storage system in a polarization instrument is proposed on the basis of the energy storage requirements of an induced polarization (IP) transmitter for geophysical exploration. We focused on the energy storage system of a supercapacitor, the topology of the power converter, and the system control strategy as key technologies, and we performed theoretical research and experimental tests on the system and developed an experimental platform. The experiments validated the theoretical research on the key technologies of the supercapacitor energy storage system and demonstrated the effectiveness of the innovation. Results showed that the storage system is efficient and satisfies the energy storage needs of the IP transmitter.

The purpose of this study is to explore the effects of Chamaecyparis obtusa essential oil on the activity of autonomic nervous system. Heart rate variability (HRV), as an indicator of autonomic nervous system activity and blood pressure were measured before and after inhalation of Chamaecyparis obtusa essential oil. The systolic blood pressure was decreased by inhalation of Chamaecyparis obtusa essential oil (p<0.05). The diastolic blood pressure was not changed significantly by Chamaecyparis obtusa. High frequency (HF) power level was not changed but High frequency/Low frequency (HF/LF) ratio was decreased by Chamaecyparis obtusa essential oil (p<0.05), meaning that parasympathetic nervous system activity was not affected but sympathetic nervous system activity was decreased. These results indicate that Chamaecyparis obtusa essential oil has a modulatory effect on the autonomic nervous system activity.

An expert network administrator is not always stationed as disasters happen. In that case, it is desirable that a novice administrator is capable of taking part in network recovery operations as well. In this paper, an agent-based network management system in emergency situations is presented. We use the Active Information Resource based Network Management System (AIR-NMS) to relieve the human administrator from parts of her management tasks and present an interface that remotely can control this management system. The effectiveness of the system is demonstrated by experiments using a prototype system.

Consider the optimal design for PV system, it is apply to 3kW interconnected electric power PV system, that is a point of reference for 3kW PV the spread residential section system. Through the driving various practical system, we look into that for efficiency of generation and stability of interconnected system. Using obtained data acquisition, It can be suggest that installation and management for system parameter to optimal design maximum generation electric power. PV system have some losses that are variation radiation, shadow, change temperature, unbalanced grid connection, serial circuit loss, MPP deference loss, PCS loss and so forth. Using obtained various performance characteristic result, we can make database in the future, through the this study, we can get the reliance and have regard to spread PV system.

BIPV(Building Integrated PV) system can expect dual effects that reduce expenses for establishment of PV system by adding new function as outer covering material of building expect producing the electricity. But, there are many generation differences according to the exterior environmental facts(solar cell away, design and installation condition of interactive inverter system) Therefore, it is difficult to optimum design. Consequently in advance design system, we experiment 3kW BIPV(Building Integrated PV) generation. We concrete PV system efficient application of variable. BIPV system that is proposed in this paper, was established in Solar Energy research center of Chosun University, composed with system. This research is a basic study for application of building integrated photovoltaic system for builing.
