According to the increase of organizational complexity and the change of rapid information technology environment, many firms have shifted their information technology(IT) strategy from developing information systems in-house to purchasing application software such as Enterprise Resource Planning(ERP) Systems. Marketing and Sales functions within a Korean automotive part company include developing new assembly products, determining pricing, taking customer's orders, and shipping assembly products to customers. Marketing and Sales Information System(MSIS) in ERP system plays an important role in next Production Planning process. MSIS also makes management reporting and decision making faster and more uniform throughout an organization. MSIS promotes thinking about corporate goals, as opposed to thinking only about the goals of a single department or functional area. This paper intends to design and implement a MSIS in ERP systems for Korean automotive part company using object-oriented methodology In order to accomplish the implementation of MSIS in ERP system, we employed UML as its standard modeling language. In this study, four diagramming techniques such as use case diagram, sequence diagram, class diagram, component diagram among eight modeling techniques are used for analyzing hierarchical business process. In traditional marketing and sales function, a company with an unintegrated information system can have marketing and sales data that is data redundant or inaccurate. MSIS integrated in ERP system can solve the sales forecast problem, which minimizes the total costs of production, inventory, and transportation under constraints of production capacity. Also, the use of UML methodology makes S/W programmers shorten the phase of analysis and design in the implementation of MSIS system, and increase the reuse of software and the interoperability with corporate internal Information system.

Objectives : The purpose of this study was to present clinical utility of therapeutic exercise on the neck and shoulder parts based on the movement system impairment syndrome(MSIS) as Dong-Qi therapy of the Dong-Si Acupuncture and was to examine which Dong-Si acupoints were most effective and non-invasive when performing therapeutic exercise of the MSIS. Methods : Totally eight therapeutic exercises correspondent to eight neck and shoulder MSIS were summarized and tabulated from the Diagnosis and Treatment of Movement Impairment Syndrome and Movement System Impairment Syndromes Of The Extremities, Cervical and Thoracic Spines by Sahrmann SA. Together with the MSIS summaries, acupuncture points and Dong-Qi therapy were summarized and tabulated from Yangweijiequanji 1 and Yangweijiequanji 2 by Yangweijie. According to the posture and movement of the MSIS exercise, effective and non-invasive acupoints were selected. Thereafter, clinical pilot study which five normal volunteers participated in were performed to examine whether these acupoints resulted in any side effects of acupuncture therapy such as pain and distortion of the needle during the MSIS exercises. Results : Through clinical pilot study, ZhongZi, ZhongXian, ZhengJin, ZhengZong and MuLiu in a sitting position, and HuaGuYi, ZhongZi and ZhongXian in a supine position were finally determined as safe and non-invasive Dong-Si acupoints to treat cervical pain. In terms of shoulder pain, ZuQianJin, ZuWuJin, HuaGuEr and JianZhong in a supine position, SiHuaZhong, ZuQianJin, ZuWuJin, QuLing, JianZhong, ShenGuan and JiuLi in a standing position, and ZuQianJin, ZuWuJin, HuaGuEr, QuLing and JianZhong in a prone position were finally accepted as safe and non-invasive Dong-Si acupoints. Conclusion : It is concluded that Dong-Si acupoints can be safely and non-invasively used together with therapeutic exercises of the MSIS to treat cervical and shoulder pains.

Objectives: This study shows feasibility and suitability of a microelectromechanical system inertial measurement unit(MEMS-IMU) as a helpful measurement device for evaluating movement system impairment syndrome. Methods: We reviewed articles of two fields in this study. First, we reviewed articles about movement system impairment syndrome(MSIS) as a brand new viewpoint of diagnosing and treating musculoskeletal pain. Second, we reviewed articles about conventional motion analysis system and inertial measurement unit(IMU) to show the superiority of IMU in analyzing the human movement. All papers were searched by SciVerse, world largest search engine and database about many academic fields including engineering and medicine. Results: Some physical quantities of human motions can be useful to the diagnosis of MSIS, and those data can be obtained by the MEMS-IMU without the weak points of the conventional motion analysis systems. Conclusions: Using MEMS-IMU as a measurement unit for diagnosing and evaluating MSIS is feasible and can be extended to many further studies.

This study proposes a circulating current reduction method that uses high-frequency voltage compensation when carrier phase difference occurs between two inverters in MSIS. In MSIS, inverters are configured in parallel to increase power capacity and to increase efficiency by using inverters only as needed. However, in the parallel inverter structure, circulating current is inevitably generated. Circulating current increases the stress on the switch, adversely affects the current control performance, and renders load sharing difficult. The proposed method compensates for the output voltage reference of the slave module by using the high-frequency voltage so that the switching pattern of each module is matched even in asynchronous carriers. The validity of the proposed method is verified by simulations and experiments with 600 W IPMSM.

본 논문은 Modular Scalable Inverter System(MSIS)에서 두 인버터 간에 캐리어 위상차로 인해 순환전류가 발생할 시 고주파 전압 보상을 이용한 순환전류 저감기법을 제안한다. MSIS는 인버터를 병렬로 구성하여 전력용량을 증가시키고 필요에 따라 선택적으로 사용하여 효율을 높인다. 하지만 병렬 인버터 구조에서는 필연적으로 순환전류가 발생하여 고주파 전압 보상을 이용하여 두 인버터가 동일한 스위칭 패턴을 출력하게 하여 주파수 성분의 순환전류를 저감한다. 제안한 방법의 유효성은 600W IPMSM를 부하로 한 MSIS 축소 모델에서 시뮬레이션을 통해 검증하였다.

Official Development Assistance(ODA) Project is initiated to assist a developing country economically and to promote its welfare. Support on training and information system development are the primary elements in the maritime safety field. The maritime safety information system(MSIS) of ODA projects deals with maritime safety information of developing nations and ensures an inter-operability between other systems. Therefore, it is required to develop MSIS based on the Universal Hydrographic Data Model(UHDM) of International Hydrographic Organization(IHO). In this paper, we have analyzed the current status and operational process of UHDM established by IHO. Oil spill response system was selected as an example of MSIS project and, also, considered the application results to the maritime safety field of UHDM.

In a rapidly changing IT and business management environment the demand for competent IS personnels is increasing. However, it is ironic that the number of IT and IS majors has sharply decreased as well as the widespread skepticism of IS identity. This research suggests directions to differentiate MIS to other IT majors, diversify IS core competency and make general improvements in MIS curriculum. The research recommend the courses of IS Strategy and policy, ITA/EA, Global IT Management, Emerging Technologies, DW/DM, BI, IT Service Science, Project Management, IT Consulting and integrated capstone which are few in Kore universities. This research also stress the course of soft skills like business communication, team building, analytic/logical thinking, rational problem solving and so on as a important IS competency. The pedagogy of course is important, so the research recommend the internship, mentoring programme, lecturers in industry according to industrial - educational cooperation.

We measured the terrestrial nightglow of OI $6300{\AA}$ in the thermosphere (~250km) using a ground-based Fabry-Perot interferometer at the King Sejong Station, Antarcticfrom March through September, 1997. The King Sejong Station is located at high latitude geographically ($62.22^{\circ}S,\;301.25^{\circ}E$) but at mid latitude geomagnetically ($50.62^{\circ}S,\;7.51^{\circ}E$). It is therefore the strategic location to measure the temperatures of the thermosphere in the Southern Hemisphere associated with both solar and geomagnetic activities. In this study, we analyzed the observed temperatures inrelation to F10.7 and Kp indices to examine the effect of the solar and the geomagneticactivities on high-latitude neutral thermosphere. During the observing period, the solaractivity was at its minimum. The measured temperatures are usually in the range between about 600~1000 K with some seasonal variation and are higher than those predicted by semi-empirical model, VSH (Vector Spherical Harmonics) and empirical model, MSIS (Mass-Spectrometer-Incoherent-Scatter)-86.
