The problems in software cost management are well known. Cost estimates are too low. Software development projects frequently have cost overruns, which are due to poor estimates. A fair amount of work have been done toward developing cost estimation models. These models vary in their outputs (e. g., total cost, manning schedule) and in the factors used to calculate their estimates. They also vary with regard to the type of formula, parameters, use of previous data, and staffing considerations. This paper will distinguish them by the type of formula they use to calculate total effort and staffing level, and will discuss enough models to demonstrate the characteristics of each model category.

인지라디오 네트워크는 현재 주파수 사용 현황을 인지하여 허가받은 주 사용자가 사용하지 않는 채널을 통해 데이터 통신을 하는 기술로써, 이러한 유휴 채널을 효율적으로 이용하기 위해서는 스펙트럼 할당 기술이 중요하다. 하지만 인지라디오 네트워크는 기존의 네트워크와는 달리 사용가능한 스펙트럼이 유동적이므로 자원 할당 시 이러한 자원 변화를 효율적으로 활용할 필요가 있다. 본 논문에서는 인지라디오 사용자들 간의 공평성과 시스템 수율을 동시에 만족시키기 위해 비례공정 채널할당기법을 적용하였다. 이때 유동적인 인지라디오 채널 변화를 고려하여 인지라디오 네트워크의 사용자 간섭 확률을 줄일 수 있도록 기존의 스케줄러를 수정한 스펙트럼 할당기법을 제안하였다.

This study investigates the application of management information systems to the quality of local government financial reports, especially the principle of transparency and the law of accountability, which have been measures of financial statement performance evaluation. The study was conducted in Enrekang Regency, Indonesia, which, based on the results of the examination, the Supreme Audit Board reported the status of Disclaimer, Fair with Exceptions, and Fair without Exceptions for three years each. This study used a sample of 35 respondents, finance department employees who worked on local government financial reports. Descriptive quantitative data were collected using a questionnaire instrument, then with the assistance of the Program Solution and Product Statistics (SPSS) Program, data were processed to test hypotheses. The results showed that the use of management information systems based on information and communication technology (ICT) had a significant influence on the quality of local government financial reports. The findings of this study indicate that the application of ICT-based management information systems affects the accountability and transparency of local government financial reports. This finding is reinforced by the use of the principles of government agility in the form of government apparatuses that apply responsive dexterity, flexibility agility, and competency agility.

본 논문에서는 선박 내 IT 서비스에 대한 요구에 부응하기 위해 적응적이고 합리적인 무선 주파수를 활용하는 인지무선 기술 중 최초 표준인 ECMA-392 네트워크를 사용한다. 먼저, ECMA-392 기반 네트워크에 대해서 알아보고, 디바이스에게 채널 할당을 위한 고려사항 및 문제점을 살펴본다. 그리고, ECMA-392 MAC 프로토콜에서 디바이스 그룹들이 요청하는 채널을 효율적으로 보장하기 위한 공평한 채널 자원 할당 방법을 제안한다. 새로운 디바이스 그룹과 기존의 디바이스 그룹들에게 채널 할당 파라미터를 고려하여 공평하게 채널들을 재할당할 수 있는 방법이다. 시뮬레이션 결과는 제안된 방식이 기존의 방식에 비해 데이터 수율을 향상시키고 있음을 나타낸다.

Objectives : To evaluate the effects of arthroscopic acromioplasty and debridement for partial thickness articular side rotator cuff tears, Method: We divided 97 patients into 2 groups according to treatment protocol, with both groups having confirmed intra-articular partial tears of the rotator cuff. In group Ⅰ, we debrided the frayed and fibrotic cuff margin while in group II, we performed subacromial decompression in addition to debridement. After the surgery we checked all the patients with the modified UCLA shoulder rating scale. Results: The follow-up observation 12 months after surgery revealed that 44 patients in group I were rated as excellent in 32 cases, good in 10 cases, fair in 1 case, and poor in one case, while 53 patients in group II, were rated as excellent in 38 cases, good in 17 cases, and fair in 2 cases. Twenty-four month after surgery we observed that patients in group I were rated as excellent in 23 cases, good in 16 cases, fair in 4 cases, and poor in 1 case, while patients in group II were rated as excellent in 34 cases, good in 17 cases, and fair in 6 cases. Conclusion: The use of acromioplasty on partial thickness tears of rotator cuff, even in the cases of intra-articular nature, is preferable to the procedure performed without it.

Structure is one of the most important components in designing chairs, since a chair should support the weight of users and make them feel comfortable. However, previous studies have focused on examining the materials and the techniques of processing of chairs, but less on studying the structures to facilitate human friendly use enough to influence the change of the current chair design. The purpose of this study is to analyze the composition element in structure of the chair design specifically from 2000 to 2008 the fundamentals to achieve quality chair design. This study examined 386 chairs which the most reputable furniture fair, the Milan International Furniture Fair exhibited from 2000 to 2008. 386 chairs were chosen from 72 companies which passed the popularity and ranks. 24 Components of the structure of chairs were used to annalize the 386 chairs. The structural types of chair design included 51 kinds. Among them, the most representative types appeared to be 5 kinds. Particularly, the single structure chair was comprised of 25%, its productivity has increased steadily since 2004 which indicated that the structure of chair has become simplified. According to the components of chair, classified structure types were analyzed into (1) a single structure consisting of one component, (2) a simple structure with two components, (3) a complex structure with three components, and (4) a multiple structure with four components. The majority of chair types followed the order of the single structure, simple structure, complex structure, and multiple structure. The results of the analysis on the structure of chairs indicated that the structure of chairs has been changed toward single type No. 24 and simple type No. 6+13.

Congestion in WSN increases energy dissipation rates of sensor nodes as well as loss of packets and thereby hinders fair and reliable event detections. We find that one of the key reasons of congestion in WSN is allowing sensing nodes to transfer as many packets as possible. This is due to the use of CSMA/CA that gives opportunistic media access control. In this paper, we propose an energy efficient congestion avoidance protocol that includes source count based hierarchical and load adaptive medium access control. Our proposed mechanism ensures load adaptive media access to the nodes and thus achieves fairness in event detection. The results of simulation show our scheme exhibits more than 90% delivery ratio with retry limit 1, even under bursty traffic condition which is good enough for reliable event perception.
