소프트웨어 품질 향상을 위해 결함을 조기에 발견/수정하는 것은 중요하며, 대부분의 소프트웨어 기업과 관련 커뮤니티는 이를 위해 테스트 단계에 노력을 집중하고있다. 하지만 테스트 단계에서 결함을 검출하는 것은 시기적으로 늦은 편에 속한다. 소프트웨어 결함 수정 비용은 결함의 발견 시기가 늦어질수록 급격하게 증가하기 때문에 테스트 단계에서의 소프트웨어 품질 향상 활동은 비효율적이다. 본 논문에서는 테스트 이전의 단계에서 조기에 결함을 발견/수정할 수 있는 코드 검토 방법을 더 효율적으로 활용 할 수 있는 방법을 제시한다. 제안하는 방법은 컴파일 에러 데이터를 저장하고 이를 통계적으로 분석한 데이터를 활용해 코드 검토를 수행하는 것이다. 이 방법을 적용하면 더 효율적으로 소프트웨어 품질 향상을 이끌어낼 수 있을 것으로 기대된다.

In this paper, we investigated 2-DOF haptic device and the method of virtual environment modeling for virtual reality. We designed an modified five bar link system to improve the performance. The haptic control system is composed of calculating kinematics and statics, controlling actuator, and describing the virtual environment. Using this system, we realized the virtual spring model and the freely falling ball model.

In this paper, a ship-cable-vehicle system's static configuration is shown obtained by solving cable nonlinear statics. Eigenfrequencies of the cable were calculated by the frequency domain analysis application of the linearized cable dynamic equations. Also extreme tensions in a slack-and-snapping long vertical cable were calculated by the clip-ping-off model.

Web Contents have been evolved from statics, dynamics contents to Mashup service. In recent years, Mashup which can creates new contents by mixing different services is topic on the web service. But, Mashup is only concentrate on making new contents to provide for client. In this paper, we propose the policy of composing services and client-friendly UI.

This paper presents how to develop visual design tools for construction of strut-and-tie models(S (STM). STMs have shown internal force flows for dimensioning and proportioning of D-regions of reinforced concrete structures. In order to select an appropriate strut-and-tie model some interactive graphic tools are necessary to help designers compare alternatives by changing the geometry of initial STM. This study proposes to use force polygons representing the equilibrium state of STM. The change of STM dynamically shows change of force magnitudes by force polygon. Once the geometry of STM is determined the detailing design process is required in the next procedure.

Natural draught cooling towers often develop visible crack structures as consequences of progressive damage processes over their life-time. The aim of this paper is a numerical demonstration of the progressive damage process of cooling towers, representatively for the reinforced concrete structures, in order to improve the durability and extend the life-time of structures subjected to such damage processes. For the analyses, the applied material model for reinforced concrete will be briefly introduced. An existing natural draught cooling tower with a pronounced crack structure, in which this crack structure indicates the typical damage pattern of large cooling towers will be numerically simulated. The change of dynamical behavior of the structure with regard to natural frequencies, reflecting the global damage process due to the degrading stiffness of the structure in dependence of the load type and intensity, will be presented and discussed.

Before economical crisis in 1997, domestic company focused on increasing the size of outward experience which including organization. The result of increasing outward experience without substance was economical crisis, so after that time, many companies have been changing their focus from insourcing to strengthen the core competence to secure global market. This is becoming a cause of following that companies are reducing their outward experience. Especially, to process tasks more effectively and to cope with rapid change of business environment, such as incoming raw material from overseas/high raising of salary/rising property prices, many companies decided outsourcing method. At most of hypothesis, the result was that outsourcing can affect positively to the business. First, introducing of outsourcing during focusing on core competence can be positive effect for company performance such as business management /productivity /procurement /administration /product competitiveness /technology. Second, the result that analyzed based on a point of view of population statics after outsourcing was positive effect at the most of research. Third, result of effectiveness for every outsourcing type classified by 4M was also can be positive at the most of research. Fourth, the characteristic of population statics can be positive effect at the most of category when select outsourcing companies. Research result of outsourcing was various based on the goal of outsourcing. It is revealed by investigation of domestic/overseas treatise that there are opposite two opinions. In this research, there is no consistent result that the outsourcing can give effects on business performance, but most of hypothesis indicates that outsourcing can give positive effect on the business performance.In this research, based on the outsourcing intensity, mutual relation was analyzed. The assumption of the reason of outsourcing is economical and organizational. First, sampling numbers of research was too small so it is too difficult to get significant business performance result. (Sampling : 150, Replied : 106, Rate of Reply : 71%) Second, tried to compare significant differences of outsourcing methods which were divided based on 4M, but the there is gaps between the number of Cell and too difficult to make replier understand. Third, it is tried to find the degrees of effect that the point of view of popular statics can effect on business performances and selection of outsourced companies.

The Studying is on developing precision of the moisture information on a soil. We used the data of AQUA AMSR-E which were obtained by Direct Receiving System in Korea Meteorological Administration(KMA). Although we know the Soil Moisture Information(SMI) helps the numerical weather model to produce the realistic results, we couldn't do it for the problem on a spatial resolution of the data is too low to apply. So we've tried to develop in a spatial resolution by using the AMSR-E data with a Digital Elevation Model(DEM) and Normal Difference Vegetation Index(NDVI) from AQUA MODIS and compared the difference between their information in statics. The result is more precise than the simple algorithm by a polarization ratio, and we could get the better result to use in forecast practically, if it's apply to get more detail in the vegetation temperature.

This was descriptive research aimed at determining the effects of emotional labor, nursing informatics competency, and nursing service environment on the nursing performance of convalescent hospital nurses. One hundred thirty-one nurses participated in this survey. The collected data were analyzed using the SPSS statics18 program. The distribution of the research variables and general characteristics were analyzed by frequency analysis and descriptive statistics. The correlation between emotional labor, nursing informatics competency, nursing service environment, and nursing performance was analyzed by the Pearson correlation, and the influencing factors were hierarchical multiple regression analysis. As a result of the study, the average nursing performance was 65.5 (±8.5) points, emotional labor was 27.2 (±5.6) points, nursing informatics competency was 91.3 (±15.7), and the nursing service environment was 88.2(±16.0) points. The nursing performance showed a positive correlation with the nursing informatics competency (r=.32, p<.001) and nursing service environment (r=.25, p=.005). Nursing informatics competency was the biggest factor affecting nursing performance, and the nursing service environment had no significant influence. Among the general characteristics, marriage status and position also affected the nursing performance. The explanatory power of this regression model was 35.2% and was statistically significant (F=9.815, p<.001).
