성공적인 소프트웨어 프로젝트 수행을 결정짓는 중요한 작업 중의 하나는 프로젝트 개발 초기에 소프트웨어 개발 비용을 정확하게 산정하는 것이다. 정확한 산정을 위해서는 빠르게 변화하고 있는 개발 환경 및 기술 변화에 따른 변경 요인을 비용 산정 과정 시 반영시켜야 하며 이를 위해서는 적절한 보정계수 선정과 보정계수 값 적용이 중요시된다. 이에 본 논문에서는 소프트웨어 개발비 대가기준을 위한 어플리케이션 유형 보정계수와 언어 보정계수 산정을 위해 AHP 기법을 적용하였다. 또한, 민감도 분석을 통하여 각 판단 기준이 보정계수에 미치는 영향을조사하였다. 결론적으로, 어플리케이션 유형 보정계수 값은 처리 복잡도에 비해 데이터관리 복잡도와 제어 복잡도에 민감하게 반응하며 또한, 언어 보정계수 값은 디버깅 시간에 비해 개발인력의 보편성과 개발코딩 시간에 더 민감하게 반응하였다. 향후, 연구과제로는 국내의 소프트웨어 개발 환경과 기술을 적절히 반영시킬 수 있는 추가적인 보정계수 결정과 적절한 보정계수 값 조정에 대하여 연구할 것이다. 또한, 언어 보정계수에서는 구체적인 프로그래밍 언어를 들어 좀더 세부적으로 구분한 후 보정계수를 산정하고자 한다.

This paper is to investigate the shrinkage properties of high performance concrete (HPC) with mixture adjustment by using mock-up specimens. HPC with mixture adjustment needed a higher dosage of SP agent due to fluidity reduction and a larger dosage of AE agent due to the reduction of air content. Setting time of HPC with mixture adjustment exhibited earlier than that of control HPC by as much as 6 hours. HPC with mixture adjustment gained more than 70MPa of compressive strength. Autogenous shrinkage of Control HPC was found to be $-340\times40^{-6}$ at 49days when the expansion value by thermal effect was excluded and HPC with mixture adjustment $-175\times10^{-6}$, which was the half of the value of control HPC. Drying shrinkage of center section of HPC with mixture adjustment showed similar tendency with autogenous shrinkage because of no internal moisture movement, while surface section had larger drying shrinkage. The specimen embedded with reinforcing bar had smaller deformation caused by confinement of reinforcing bar.

Through information hiding technique, secret message can be hidden in pictures. Stego-image quality and hiding capacity are two important metrics for information hiding. To enhance these metrics, many schemes were proposed by scholars in recent years. Some of them are effective and successful, but there is still a room for further improvement. A high capacity information hiding scheme (PAMO, Pixel-value Adjustment with Modulus Operation Algorithm) is introduced in this paper. PAMO scheme uses pixel value adjustment with modulus operation to hide confidential data in cover-image. PAMO scheme and some referenced schemes are implemented in Python and experiments are carried out to evaluate their performance. In the experiments, PAMO scheme shows better performance than other methods do. When secret message length is less than 72000 bits, the highest hiding capacity of PAMO can reach 7 bits per pixel, at the same time the PSNR of stego-images is greater than 30 dB.

Purpose: The study was done to identify adjustment to hospital life of school aged children. This research was designed as a descriptive study. Method: A convenience sample of 186 patients who were hospitalized children, 6~12 years old. The instrument in this study were developed by researcher and constructed to include 5 sub categories about adjustment to hospital life. They ask children to rate each item on 5 Likert scale. The data were analyzed by SPSS Win Program. Result: The mean average score of adjustment to hospital life was 91.75(SD 11.22); the social support revealed the highest value, followed by self-esteem, stress on disease, stress on hospitalization, and defense strategies. There was differences on bibliographic data; hospital date, disease type. The relationship between adjustment and sub categories was significant, especially in the stress on hospitalization and disease, social support and self-esteem. The relationship between coping strategies and stress on diseases was reversed. Conclusion: These results suggest that pediatric nurses need to be aware of the adjustment to hospital life. A development of nursing intervention program may be useful and critical for hospitalized school aged children.

This paper empirically verifies that the types of capital adjustment costs serve as an important mechanism in relation to investment decision-making after confirming that the investment dispersion of Korean firms is pro-cyclical and can affect business cycles. Specifically, it is found through empirical methods using corporate financial data that capital adjustment costs generally assumed to take a quadratic form in macroeconomics are asymmetric and irreversible in the Korean economy. In particular, capital adjustment costs are empirically proven to cause investment dispersion to expand given that the substitution effect of the marginal value to the marginal cost for one unit of investment in the inter-temporal investment decision is affected by that cost with regard to the resale of owned equipment assets, as opposed to new investments in equipment assets. We ultimately show, albeit indirectly, that investment dispersion can affect business cycles as capital adjustment costs influences investment decisions. What is implied is that the capital adjustment cost is not merely an exogenously deep parameter that fits the dynamics of business cycles in a macroeconomic model but could instead be a policy variable that can be endogenized through government policies.

Management is under constant pressures to achieve competitiveness in production in most manufacturing companies. The adoption of management techniques(MT) such as TQM, MRP, ERP and so on has been a logical response for better performance to many companies. Besides, these companies commonly adopt a number of such techniques with high expectation for performance improvement. However, expected improvement in performance is not guaranteed unless necessary ingredients exist for those techniques. Many research studies have focused on the nature of successful adoption of management techniques in the past. However, most studies have been related to a single technique and its effects. When more than one techniques are in use in a company, focusing on a single technique limits the value of analysis. This paper focuses the value of MTs adopted in a company in multiplicity and compares the relative characteristics of MTs one another. Especially, the purpose of this paper is to examine the comparative nature of MTs adopted In manufacturing companies and the elements of MT success in relationship with information systems and organizational adjustment for adoption of MTs. The result of the analysis shows that the more efforts are exhorted for the adjustment of information systems and organizational structures to accommodate the MTs, the more success from the adopted techniques results. However, the extent of adjustment for different management techniques differs one another due to the nature of each technique. With regard to the comparative impact of adjustment of information systems and that of organizational structures, the result shows that the latter has more direct and greater impact than the former.

The purpose of this study was to identify school adjustment groups by applying a Latent Profile Analysis(LPA) and to investigate the effects of children's emotional problems and study habits on determining the membership of these groups. LPA and multiple logistic regression were conducted using the data of 2,200 third-graders from the Korean Children and Youth Panel Study. The results are listed as follows. First, four school adjustment groups were identified: adjustment, approach to adjustment, maladjustment risk, and maladjustment group. Second, accomplishment value and mastery goal orientation were relatively strong predictors of membership of the school adjustment groups. Time management was also a significant variable that predicted the membership of maladjustment or the maladjustment-risk group. Third, attention problems and depression were the most consistent predictors of membership of maladjustment or the maladjustment-risk group. Physical symptoms and social withdrawal were also significant. Based on the results, implications for intervention to promote early school adjustment were discussed.
