In this paper, an adaptive disturbance compensation technique is used in a tracking problem, under which the tracking reference is unknown. Based on a simple disturbance observer that effectively estimates the low frequency components of disturbance, the feedforward compensation is applied in addition to the conventional feedback control. Under the proposed compensation method, sensitivity analysis is given to illustrate the effectiveness. Finally, the proposed method is applied to the tracking problem in an optical storage system.

Costal fisheries use small boat. The boats are frequently substituted with newly made boat or proper boat. When the boat which is substituted with another one after the fixed date for compensation is estimated for fisheries loss by public project, it is matter that which boat is the object for estimating average catch of fish. There are three ways in practical business. They are based on the date of spot probe, the date of conference for compensation and fixed date for compensation. In case of applying the first and the second ways, as the object of compensation is not fixed, there is problem that estimated result can be changed depending on changing boat tons even after the date of spot probe and the fixed date for compensation. Most of all, these ways are against Attached Form No.4 of the Enforcement Ordinance of Fisheries Law which regulate to calculate average catch of fish applying result of fishery for retroactively counted 3 years from the year before the year in which administrative measure day is. The other side, in applying boat tons based on the fixed date for compensation, estimated result of compensation will not change even boat substituted after the fixed date for compensation. Even though applying tons based on the fixed date for compensation, a problem still remains. If the boat get bigger after the fixed date for compensation, the then boat size must be applied for calculating average catch. But the boat get smaller, the changed boat size must be applied. Because changed small boat would be damaged less than the previous boat. And decrease in catch by changing boat into small one is not due to the project but due to the personal responsibility. This will help to increase objectivity and reliance on the compensation result. As the other objects are fixed based on the fixed date for compensation in the Act on Acquisition and Compensation of Land and Others for Public Project, it can be balanced with other object.

This study aimed to investigate a bias pattern making method with geometrical approach. The bias-cut dress has soft silhouette of drape in the garment. However, the bias cut dress has problem of satisfying the intended garment size spec. This problem occurs from various sources. The main reason is that the bias-cut fabric tends to stretch on longitudinal direction and to shrink horizontal direction when it was hung on the body. The goal of this study was to develop a bias-cut dress pattern making method satisfying the intended garment size spec. The researchers developed the geometrical method of measuring dimensional change by calculating the compensation ratio of the fabric in true bias direction. The compensation ratio was calculated by applying draping ratio of the fabric. Three types of fabrics were used in the experiment. The warp and weft crossing angle of fabric was ranged from $78^{\circ}$ to $82^{\circ}$. The fabrics stretched longitudinally 6.9~9.9% and shrank horizontally 7.2~11.0%. The compensation ratio of the bias-cut pattern for sample dress was calculated for each fabric type. Two types of experimental bias-cut dress patterns were developed for each fabric. One pattern was made with applying full compensation ratio and the other one made with applying partial ratio of the fabric. Experimental dresses were made with these patterns. The results of the evaluation showed that the bias-cut dress pattern applying the partial compensation ratio was more appropriate than the pattern applying the full compensation ratio.

이 연구에서는 중학교 학생들의 보상논리 문제해결 과정을 알아보았다. 이 연구를 위해 서울 소재 남녀공학 중학교 3개반 5개조 21명을 대상으로 하였으며, 보상논리를 주제로 한 활동의 수업내용을 참여 관찰하였고, 그 내용을 녹음하여 조사${\cdot}$분석하였다. 학생들의 보상논리 형성과정을 분석한 결과 학생들은 개인마다 각기 다른 유형의 형성과정을 나타내었다. 수학적 연산력이 뛰어나난 학생들은 비례식에 의해 보상논리를 설명하고 반비례관계와 보상논리는 같은 개념이라고 생각하는 경향이 강했고, 보존논리가 잘 발달되지 않는 학생들은 보상논리 형성과정에서 평형을 유지하려는 힘은 보존된다는 생각과 두 변인의 관계를 연관지어 생각하지 못하였다. 보상논리 형성에 성공한 학생들은 다른 학생들에 비해서 보존개념 형성정도가 높았다.

Experiencing power declines when the secondary coil is at the middle position between two primary coils is a serious problem in segmented on-road charging systems with a single energized segmented primary coil. In this paper, the topological transformation of a primary circuit and a hierarchical compensation capacitor control are proposed. Firstly, the corresponding compensation capacitors and receiving powers of different primary structures are deduced under the condition of a fixed frequency. Then the receiving power characteristics as a function of the position variations in systems with a single energized segmented primary coil and those with double segmented primary coils are analyzed comparatively. A topological transformation of the primary circuit and hierarchical compensation capacitor control are further introduced to solve the foregoing problem. Finally, an experimental prototype with the proposed topological transformation and hierarchical compensation capacitor control is carried out. Measured results show that the receiving power is a lot more stable in the movement of the secondary coil. It is a remarkable fact that the receiving power rises from 10.8W to 19.2W at the middle position between the two primary coils. The experimental are in agreement with the theoretical analysis.

There were many papers on the bilateral teleoperation system. But a few papers dealt with the controller design method in the presence of uncertainties, disturbances and measurement noises. In this paper, we propose a robust controller design framework in teleoperation, which can overcome the compensation problem that will be defined. To prove the effectiveness of the method of proposed design, comparative simulation with the existing four channel design method was performed

Generally SW industry is considered as a high value-added business area. However, many SI companies in Korea have been loosing profits in public business sector. One of the reasons of this problem is because the compensation for the change of work which occurs frequently during a project has been rarely happened. This might be because many contracts have been made as more officer-oriented one. So far, there has not been much study on this topic. So in this paper, we are going to define the change of works in SI projects, analyze the characteristics, and classify them into some categories. After analyzing the current status and related laws concerning this problem, we will suggest a way to solve this problem and show the future research topics.

In many advanced countries, most outside directors are executives, active or retired, at other firms; in other words, executives from other companies make executive compensation decisions. This situation may hinder the board of directors (BOD) in their efforts to optimize executive compensation levels objectively. Using a panel data analysis of the S&P 1500 companies, we provide supplemental evidence of whether, and to what extent, the concurrent executive employment of outside directors distorts the executive pay decisions at a given company. An unbiased fixed-effect estimation confirms that a $1.00 increase in CEO pay at outside directors' primary companies results in an approximate increase of $0.22 in CEO pay at the given company. From a policy perspective, this added agency problem - caused by the BOD and not by management - is noted as difficult to control; although a firm may establish board independence, the inherent concurrent employment of directors on a board continues to exist.

In this paper we present our research dealing with the problem of tool deflection during the milling. We try to compensate the errors by considering a new tool trajectory. In order to determine the compensated tool trajectory, the problem is divided in three steps : cutting forces model, tool deflection model and trajectory compensation. Starting from experimental data, we determine a cutting forces model., which allows us to anticipate the tool deflection along one nominal path. In order to determine the compensated tool trajectory, we propose in this paper a method of path compensation, called “mirror method”. This method of tool path optimization allows to minimize errors due to tool deflection. Several examples are processed in simulations and validated experimentally.

우리나라의 잔여지 보상제도는 크게 잔여지 매수 보상, 잔여지 감가보상, 잔여지 공사비 보상 등 세 가지로 나눌 수 있으며, 이 중 매수보상에서는 매수대상 요건이 주로 문제가 되고, 공사비보상에 대해서는 별도로 문제가 되는 부분이 거의 없다. 본 연구에서는 현행 잔여지 감가보상제도의 내용과 문제점을 살펴보고, 미국과 일본의 제도를 비교 분석하여 우리나라의 보상제도와의 차이점을 알아보고 잔여지 감가보상에 대한 정책적 대안을 마련하고자 한다.
