소프트웨어 개발 프로젝트 사업의 성패는 사업의 첫 관문인 소프트웨어 견적의 결과에 좌우되는 경우가 많다. 특히, 확정가격 계약으로 수행되는 국내의 소프트웨어 사업 관행 하에서는 견적의 잘못이 회사의 존폐로 귀결되는 경우도 있다. 견적의 핵은 정확한 원가의 파악인데, 이를 위해서는 고객이 요구한 업무량과 개발자의 생산성을 정확히 아는 데서 출발해야 한다. 문제는 고객의 요구를 사업 초기에 정확히 파악하는 것이 쉽지 않을 뿐 아니라, 개발자 자신의 생산성을 잘 모른다는 것이다. 더욱이 정보의 부족으로 프로젝트의 특성 파악을 제대로 할 수 없어서, 해당 프로젝트에 적합한 생산성 보정계수의 적용이 어렵다는 점이다. 본 사례는 삼성SDS가 금년도에 종료된 수십 여 개의 프로젝트로부터 수집한 생산성 영향인자들이 생산성에 어떠한 영향을 어느 정도나 미치는 지를 분석한 것이다. 본 분석을 통하여 생산성에 영향을 미치는 주요 인자들을 식별할 수 있었고, 이들이 미치는 영향 정도를 바탕으로 견적에서 활용할 수 있는 다양한 파라메트릭 모델을 만들 수 있었다. 본 논문은 생산성 영향인자의 식별과 이들을 이용한 견적용 파라메트릭 모델의 개발 방법을 다루었다.

Knowledge Management is introduced by many big companies with the development of Information Technology. Although researches about the enabling conditions have been progressed, but there are few study of relationship between KM stages and enabling conditions, and performance. This study focus on the KM four activities and KMS(Knowledge Management System), which is on the Samsung SDS's KMS(they called ARISAM) and related with team performance. We are propose some points to the managerial implications.

In this paper, we propose a friend recommendation scheme that takes into consideration the attribute information of a POI and a user's movement patterns. The proposed scheme broadly consists of a part that filters out other users who have different preferences by calculating preferences using the attribute information of users and a part that finds a moving trajectory close to that of a user with a pattern-matching scheme. To verify the superiority of the proposed scheme, we compare it with existing schemes through various performance evaluations.

The corporate R&D(Research and Development) has a primary role of new product development and its potential is the most crucial factor to estimate corporate future value. However, its systemic inadequacies and inefficiencies, the shorten product life-cycle to satisfy customer needs, the global operations by outsourcing strategy, and the reduction of product cost, are starting to expose to R&D business processes. The three-phased execution strategy for R&D innovation is introduced to establish master plan for new R&D model. From information technology point of view, PLM(Product Life-cycle Management) is one of the business total solutions in product development area. It is not a system, but the strategic business approach that collaboratively manage the product from beginning stage to end of life in all business areas PLM functions and capabilities are usually used as references to re-design new R&D process. BPA(Business Process Assessment) and 5DP(Design Parameters) in PI6sigma developed by Samsung SDS Consulting division are introduced to establish R&D master plan and re-design process respectively. This research provides a case study for R&D process innovation. How process assessment and PMM(Process Maturity Model) can be applied in business processes, and also it explains process re-design by 5DP method.

Objective : Panic disorder is a chroni, debilitating illness, and has been known to be affected by high anxiety sensitivity and a poor quality of life. We examined if 12 weeks of pharmacotherapy with escitalopram could affect anxiety sensitivity, quality of life, and general disability in patients with panic disorder. Method : We enrolled 27 patients who met the DSM-IV-TR criteria for panic disorder, with or without agoraphobia, and completed 12 weeks of escitalopram treatment. We enrolled 29 normal control subjects who were matched for age and sex compared with the panic patients. All subjects were assessed using the Hamilton Rating Scale for depression (HAM-D), Hamilton Rating Scale for Anxiety (HAM-A), Panic Disorder Severity Scale (PDSS), Anxiety Sensitivity Index-Revised (ASI-R), WHO quality of life assessment (WHO-QOL) and Sheehan Disability Scale (SDS) before and after 12 weeks of treatment. Result : Panic disorder patients had a higher Anxiety sensitivity, a poorer Quality of life, and significant disability than normal control subjects at baseline. After the treatment, Panic disorder patients showed significant improvement in the severity of panic symptoms in terms of the HAM-A p<0.001), HAM-D (p<0.001) in addition, the reached a remission state in terms of the PDSS score. They also showed significant improvement in the ASI-R (p<0.001), WHO-QOL (p<0.001) and SDS (p<0.001), but mean scores of the ASI-R, WHO-QOL and SDS in panic disorder patients were did not reach normal levels. Conclusion : This study suggests that 12 weeks of pharmacotherapy with escitalopram could improve anxiety sensitivity, quality of life, and disability in panic disorder patients, although their anxiety sensitivity, quality of life and disability were not yet normalized after short-term pharmacotherapy. Thus, long-term pharmacotherapy may be necessary for panic disorder patients in order to get an optimal clinical response in terms of anxiety sensitivity, quality of life, and general disability.

Objective: Anxiety has been shown to influence functional impairment in patients with attention deficit hyperactivity disorder (ADHD). This study aimed to compare functional impairment in subjects with and without adult ADHD and to investigate the associations among trait anxiety, functional impairment, and ADHD symptom severity. Moreover, the effects of ADHD symptom subtypes on trait anxiety and functional impairment were also examined. Methods: The sample included 209 adults between the ages of 20 and 31 years. Fifty-one adults received a diagnosis of ADHD, and an additional age, sex-matched group of 51 adults comprised the adult control. Participants were assessed with Conners' Adult ADHD Rating Scales (CAARS), the Beck Depression Inventory (BDI), the Spielberg Trait Anxiety Inventory (STAI-T), and the Sheehan Disability Scale (SDS). The relationships among ADHD severity, anxiety, and functional impairment were investigated using Pearson's correlation analysis. Subtypes of ADHD symptoms that predicted anxiety and functional impairment were investigated using regression analyses. Results: Adult ADHD patients significantly differed from normal control subjects according to BDI, STAI-T, and SDS assessment. Significant positive correlations were noted between ADHD severity, anxiety, and functional impairment. Multiple linear regression analysis confirmed anxiety as a mediator between functional impairment and ADHD CAARS symptom subscales. Conclusion: Patients with adult ADHD showed higher levels of anxiety, depression, and functional impairment. Additionally, ADHD symptoms and anxiety impacted subject functional impairment. Our results suggest that anxiety may be a strong mediator between ADHD severity and functional impairment.

Understanding exoelectrogenic reactions of the bioanode is limited due to its complexity and the absence of analytics. Impedance and thermodynamics of bioanode, abiotic anode, and riboflavin-amended anode were evaluated. Activation overpotential of the bioanode was negligible compared with that of the abiotic anode. Impedance spectroscopy shows that the bioanode had much lower charge transfer resistance and higher capacitance than the abiotic anode in low frequency reaction. In high frequency reaction, the impedance parameters, however, were relatively similar between the bioanode and the abiotic anode. At open-circuit impedance spectroscopy, a high frequency arc was not detected in the abiotic anode in Nyquist plot. Addition of riboflavin induced a phase angle shift and created curvature in high-frequency arc of the abiotic anode, and it also drastically changed impedance spectra of the bioanode.
