This study seeks to determine the effect of the application of accounting information system (AIS), internal control system, and human resource (HR) competency on the quality of local government financial statements (FS). This study uses agency theory and compliance theory. Agency theory is used to explain that there is a link between the society as the principal and the government as the agent. Compliance theory is a theory, which states that every agency is obliged to comply with regulations because the law-drafting authority has the right to dictate behavior. The population in this study were employees of the financial division of local government organizations in one of the districts in Central Java, Indonesia. The total samples in this study was 106 respondents. The data used are primary data taken from distributing questionnaires to respondents. The method of analysis used to test the hypothesis was multiple linear regression analysis. The results of hypothesis testing indicate that HR competency has an effect on the quality of FS; however, the application of AIS and internal control system has no effect on the quality of FS. The implication of this research underlines the importance of HR competency to improve the quality of local government FS.

Korean agriculture and rural sector has undergone a wide range of reform after the Uruguay Round. Major policy measure is to put finances of huge budget from tax payers since 1994 in preparation of the Rural Development Strategy and Reform Program. Both in the total amount and individual size of the subsidy and loan for eligible farmers and farmers group are large and drastically enormous than any other programs in the past. The strategy adopted was a bottom-up approach, Particularly in selecting the project with local autonomy. However, it has been still criticized as the form of centralized control of budget and decsion. In terms of the program effectiveness too, it is doubtful to judge that Korean agriculture is in a road to getting the international competetiveness as targeted. Since the local autonomy was started in 1995, the political structure has been settling in a way to be more locally institutionalized. Rural development policy, as the key point of economic and industrial dimension of local autonomy, should be initiated and practiced in real term by the local government. This paper, in this concern, in reviewing the past rural development prolicy and programs, discussed the necessary issues relevant to legal bases of land uses in Korea. Further, the direction of increasing local automous power of local government was discussed in the senses of budgetary control and decision. The power and budget should be allocated more to the rural development plans of local government in order to fulfilize integrated rural spatial development in this new era of globalization.

멀티캐스트를 이용한 멀티미디어 응용에서는 다수의 수신자들로부터 피드백을 수신할 경우 폭주로 인한 혼잡이 발생하여 전송률이 낮아지는 문제가 발생한다. 이를 위해 계층적 대표자 기법이 제안되었다. 그러나 수신자 전체를 고려한 전송률 조절로 인하여 혼잡이 없는 지역의 전송률도 같이 낮아지는 문제가 발생한다. 본 논문에서는 이러한 문제를 해결하기 위해 지역대표자를 두었다. 지역대표자는 해당 그룹의 전송률이 최소 유지임계치 미만일 경우, 혼잡 수신자를 전송률 계산에서 제외시켜 다시 계산한다. 이렇게 함으로써 혼잡이 발생하지 않는 지역의 전송률이 같이 낮아지는 문제를 개선하였다. 실험을 통한 결과를 볼 때 기존의 기법보다 더 안정적인 전송률로 조절됨을 보였다.

This paper summarises theoretical and experimental work on the feedback control of sound radiation from honeycomb panels using piezoceramic actuators. It is motivated by the problem of sound transmission in aircraft, specifically the active control of trim panels. Trim panels are generally honeycomb structures designed to meet the design requirement of low weight and high stiffness. They are resiliently-mounted to the fuselage for the passive reduction of noise transmission. Local coupling of the closely-spaced sensor and actuator was observed experimentally and modelled using a single degree of freedom system. The effect of the local coupling was to roll-off the response between the actuator and sensor at high frequencies, so that a feedback control system can have high gain margins. Unfortunately, only relatively poor global performance is then achieved because of localisation of reduction around the actuator. This localisation prompts the investigation of a multichannel active control system. Globalised reduction was predicted using a model of 12 channel direct velocity feedback control. The multichannel system, however, does not appear to yield a significant improvement in the performance because of decreased gain margin.

A rerospective review of fifty patients with carcinoma of hypopharynx treated with $RT{\pm}surgery$ was studied for eleven-year period from 1974 to 1984. Of the 50 patients,46 were pyriform sinus in origin, 4 were posterior pharyngeal wall. Eighty-eight percent of patients were locoregionally advanced(stage III, IV) and 78% of patients presented conical lymphadenopathy. 5-year disease-free survival rate of the pyriform sinus ca. was $25.4\%$ in RT alone group, $80\%$ in combined modality group and $30.6\%$ in overall. Local control rate with RT alone in early stage (II) was excellent $(100\%)$, however combined modality appears to be better for local control$(80\%)$ in advanced stage (III, IV) as compared with that of RT alone group $(32\%).$ On basis of this study, RT alone is effective in terms of local control and functional preservation in treatment of early stage of pyriform sinus ca. while surgery can be reserved for salvage purpose when RT fails and combined modality is recommended in patients with locally advanced stage for better local control and survival.

Background: Local anesthetic infiltration at the site of a surgical wound is commonly used to control postoperative pain. In this study, we examined the effectiveness of continuous local infiltration at an abdominal surgical site in patients undergoing anterior lumbar interbody fusion (ALIF) surgery. Methods: Sixty-one patients who underwent ALIF surgery were enrolled. For thirtyone of them, a continuous local anesthetics infiltration system was used at the abdominal site. We collected data regarding the patients' sleep quality; satisfaction with pain control after surgery; abilities to perform physical tasks and the additional application of opioids in the postoperative 48 hours. Results: The On-Q system group showed reduced visual analogue scale scores for pain at the surgical site during rest and movement at 0, 12, 24, and 48 hours; and more was satisfied with pain control management at the first postoperative day (7.0 ± 1.2 vs. 6.0 ± 1.4; P = 0.003) and week (8.1 ± 1.6 vs. 7.0 ± 1.8; P = 0.010) than the control group. The number of additional patient-controlled analgesia (PCA) bolus and pethidine injections was lower in the On-Q group (PCA: 3.67 ± 1.35 vs. 4.60 ± 1.88; P = 0.049 and pethidine: 2.09 ± 1.07 vs. 2.73 ± 1.38; P = 0.032). Patients who used the On-Q system performed more diverse activity and achieved earlier ambulation than those in the control group. Conclusions: Continuous wound infiltration with ropivacaine using an On-Q system may be effective for controlling postoperative pain after ALIF surgery.

This paper proposes about decentralized control approach based Leader-Follower formation control using LOS (Line of Sight) algorithm and unknown input observer. The position of robots which is a basic information in multi-robot or single robot motion control is determined by localization algorithm fusing UPS (Ultrasonic Position System) and kinematics model. For formation control, a decentralized control approach individually installing a local controller in leader and follower robot is adopted. Leader robot is controlled to track a specified trajectory by LOS algorithm, and the other robots follow the leader by local controller based on tracking platoon level function, self-sensing data and estimated information from unknown input observer. The performance of proposed method is proven through the formation experiment of two vehicle models.

This paper describes a new method for control of large-scale system by sliding mode. The concepts of control to large-scale system on the basis of VSS(Variable Structure System) control theory are used to decompose a large control problem into a two-level algorithm such that each subsystem is stabilized with local discontinuous controllers and higher level corrective control is designed to take into account the effect of interaction among the subsystems. In this paper, we show that each subsystem is controlled with repect to local continuous and higher level corrective control. This algorithm can be easily applied to multi-variable control system and obtained a continuous control in comparison With variable structure control systems. Two numerical examples are discussed as illustrations.

An efficient dynamic control algorithm that outperforms existing local torque optimization techniques for redundant manipulators is presented. The method resolves redundancy at the acceleration level. In this method, a systematic switching technique as a trade-off means between local torque optimization and global stability is proposed based on the stability condition proposed by Maciejewski [1]. Comparative simulations on a three-link planar arm show the effectiveness of the proposed method.

In this paper, we present the error control techniques for the error correction methods (ECM) which is recently developed by P. Kim et al. [8, 9]. We formulate the local truncation error at each time and calculate the approximated solution using the solution and the formulated truncation error at previous time for achieving uniform error bound which enables a long time simulation. Numerical results show that the error controlled ECM provides a clue to have uniform error bound for well conditioned problems [1].
