The aim of this paper is to compare the fundmental difference between accounting approach and actuarial approach. For this purpose, we firstly establish the dynamics of pension assets and liablity, respectively in view of accounting approach characterized by the IAS19. Secondly, we build up the actuarial asset and liability dynamic models, respectively. Thirdly, we show that the accounting amortization method is more favorable to the scheme sponsor rather than the scheme members. Lastly, I hope the this paper will contribute to understanding the difference between actuarial approach and accounting approach and furthermore be a turning point of doing reciprocal co-work between accountancy professions and actuarial profession in the field of pension study.

Abstract - To examine the protective effect of combination treatment of angiotensin II AT1-receptor blockers (ARBs) with Ca2+ channel blockers (CCBs) for high blood pressure and neointima hyperplasia, losartan and amlodipine were orally injected into telemetered-spontaneous hypertensive rats and vascular injury induced by cuff-inserted neointimal formation model in vivo. For the measurement of blood pressure, random orders of losartan 0, 4.79, 9.58 mg/kg/day, amlodipine 0, 0.48, 0.96 mg/kg/day, or higher/lower doses in combination were administered in spontaneous hypertensive rats (SHRs; n=10). For the measurement of neointimal hyperplasia, 9.58 mg/kg/day of losartan or 0.96 mg/kg/day of amlodipine in alone or combination were given for 2 weeks to cuffed C57BL/6 mice (n=6). Our results suggest that the combination therapy of high doses of losartan and amlodipine are effective in lowering systolic blood pressure (SBP) and mean arterial pressure (MAP) as compared with monotherapy of each drug, but not in combined therapy of low doses of two drugs. In protection for vascular remodeling, the combination therapy of losartan with amlodipine synergistically decreased BrdU-positive cells in neointima and DNA synthesis in [3H]-thymidine incorporation by reducing cell proliferation. Therefore, present study implies that combination of losartan with amlodipine may be effective for the treatment of hypertension and vascular remodeling such as restenosis.

Human cysticercosis caused by the larval stages of cestode Taenia solium is important public health problem in many of the developing countries including Korea. The application of computerized axial tomography has greatly assisted the diagnosis of neurocysticercosis. However many cases require serological examination for diagnostic confirmation. But there are some limiting factors in seroimmunological diagnosis for the detection of antibodies in serum or cerebrospinal fluid. One of the major problems is the non-specificity of the antigens which produce cross reaction with antibodies produced by the presence of other helminthic infections. Especially the sensitive tests such as ELISA are highly dependant on the purity of antigens used. To solve this problem many workers have tried to find species specific components of the antigens. Accordingly, the present studies were performed to determine the antigenic profile of the vesicular fluid and parenchymal antigens of metacestodes of Taenia solium based on SDS-PAGE and immunoblotting techniques. Analysis of human serum reactivities to these antigens gave the following results. 1. The SDS-PAGE of CyF₁ (vesicular fluid antigen) showed protein bands at the 116-200K, 106K, 91K, 63K, 21K and 2 faint bands at 97K, and 80K molecular weight region. Among them first 2 masses of bands were non-specific and the EITB patterns showed species specific reactive bands at the 91K, 63K, and 21K region. 2. The SDS-PAGE of CyL₁ (larval antigen) showed protein bands at the 116-200K, 106K, 91K, 80K, 63K, 43K, 31K, 21K, 14K and many faint bands. Among them, 3 bands at the region of 63K, 43K, and 14K showed species specific reactions. 3. The antibody produced by P. westermani, Sparganum and D. latum infected patients showed non-specific cross reaction with 116-200K, and 106K bands of CyF₁ and all bands of 80K, 116K and 116-200K bands of CyL₁. 4. The band at the region of 63K of both antigen showed strong positive reaction without interference and cross reaction of other helminthic infectons. Serum of nine Cysticercus infected patients examined showed positive reaction at the band of 63K without exception. The high species-specificity demonstrated by the present methods could be used to confirm serologically an infection by Taenia solium metacestodes.

一般的으로 圓筒型 回轉子를 가진 3相交流電動機의 磁界 解析에서 空隙은 一定하고 回電子捲線 電流에 의한 起磁力이 空隙起磁力에 포함된다. 本 論文에서는 空隙起磁力은 固定子捲線 電流에 의한 起磁力만이며 空隙이 圓周方向의 變數라는 점을 감안함으로써 磁氣抵抗 電動機의 解析에 圓筒型 回轉子 電動機의 磁界 解析에 의한 解析法을 適用하였다. 解析에 使用된 segmental rotor는 從來의 回轉子와 다르며 이 兩機器의 磁氣回路와 特性을 비교검토하였다. 直軸 리액턴스는 機器 構造를 나타내는 定數들로 表現되므로 모든 特性方程式도 이 定數들과 負荷角으로 나타난다. 故로 回轉子의 構造를 바꾸어서 特性을 改善할 수 있다. 定常狀態의 動作特性은 Stroboscope에 의해 測定된 負荷角에 의해 決定되었고 計算값과 잘 一致했다. Generally in the analysis of magnetic field of three phase moter which has cyrindrical rotor air gap is constant and the magneto motive force of rotor winding current is cont ned in the magnetomotive force of the air gap. In this paper, the method of the analysis of magnetic field of three phase motor was adaped in analysis of reluctance motor in which only the MMF of the stator winding exist in the MMF of the air gap and the air gap is a variable along the cyhindrical direction. The segmental rotor used in this analysis is different from the conventional one and the difference of the magnetic circuits and the performance characteristics was compared and reviewed. Since dirct-and quadrature-reactance are described with the constants which is rendered to machine configuration, all the characteristic equations is represented with this constants and load angle. And so the characteristics of this motor is improved by changing the rotor structure. The steady state performance was made by the load angle which is measured by the stroboscope. The results well coincided with the values of the computation.

This paper presents the characteristics of magnetic flux distribution and torque of the reluctance motor. Three phase segmental reluctance motor is analyzed by f.e.m. and the element equation is derived by the variational approach. The magnetic flux distribution shows minimum reluctance at direct-axis and maximum reluctance at quadrature-axis, and the leakage flux is reduced at the position of the teeth of the stator, because of the larger pole are of the rotor comparing to that of the conventional machine. As it could be obtained from theoretical equation, torque varies sinusoidally while the load changes.

As the development of infocommunicational technologies and the increase of computer utilization have accelerated the information-oriented society, the security problem of information systems is getting a growing interest and the importance of regulations and procedures for the security problem is increasing. Information systems have to secure the auditability in order to prevent the illegal leakage of information and to track down the violators of control principles. And they also need an audit trail mechanism in order to clarify the information system managers' liabilities and to visualize those users' behaviors. Fundamentally, the audit trail is used as a method for the statistical accountability that tracks down who used which resources in what time and in which order and for the claim of using charge, the maintenance of statistics, the backup and so on. Recently, with the addition of security issues that supervise and log the inappropriate use of system resources, how to track down the illegal access to the information system has become the main issue. In order to construct the audit trail mechanism as above-mentioned, this study proposes a logical model for safe audit logging system based on UNIX system, according to the utility, the security and the perpetuity of audit log and the implantation onto the existing systems.
