After enterprise get a certification in acquisition, the core requirements of ISO/TS 16949 standard is pull out the Performance Indicators by process access approach during the settlement and operation of system, and the pulled key performance indicators classified into the customer intention process, support process and management process and analyzed the effect to the management result. This study conducted with following step. Firstly, preceding research, the literature and investigation analysis about process approach method which is the special characteristics of ISO/TS 16949 standard. Secondly, each process of ISO/TS 16949 standard is classified and deduced the key performance indicators followed process access method. Finally, get a enterprise survey data related to improvement of Performance Indicator and analyzed by SPSS statistical software.

PCS(Process Computer System) is installed to monitor various kinds of process parameters in Power Plant and networked for synthetic monitor and event analysis in all site. But when an event is occured sequentially or simultaneously among the plants, it is difficult to analyze it because of different Standard-Time in each Plant. Standard-Time Receiving Device is developed to solve this problem and development procedure is descried here.

An adjusted control limit of the $\overline{X}$ chart is proposed for monitoring the continually improving processes. The continual improvement of the process implies the decrease of the process variance, which is represented by a logistic curve. The process standard deviation is estimated by the exponentially weighted moving average of the sample standard deviations from the past to the current times. The control limits are adjusted by the estimated standard deviation at every sampling time. The performance of the adjusted control limit is compared with that of the standard control limits for various cases of the decreasing speed and size of the variance. The results show that the $\overline{X}$ chart with the adjusted control limits provides better performances for monitoring the small and moderate shifts in continually improving processes.

This study suggests the organization-level standard(model and process) for quality evaluation of information systems(IS) in non-use organizations despite international standards(ISO/IEC 9126 and ISO/IEC 14598) and national standards(KS X 9126 and KS X 14598) related to quality evaluation of IS. The standard in this study is composed of quality evaluation processes, a quality model, and quality metrics. The weights of the attributes and the sub-attributes in the quality model were calculated by an analytic hierarchy process(AHP). The minimum level and the target level of each metrics were determined by brainstorming of the committee. Furthermore, the case study for the investigation of the applicability and the usability of the suggested organizational standard in the real IS development project was performed. For gaining significant benefits of the standard, both the diffusion and the experience accumulation by its continuous use are needed.

The washing characteristics of steam jet heating process have been compared with other washing processes, such as low temperature process(standard process, below $40^{\circ}C$) and high temperature process(boiling process, up to $95^{\circ}C$) with the standard soil fabric, EPMA 105. Steam jet heating process showed almost the same washing efficiency as high maximum temperature process for pig's blood and wine. This result can be explained with the higher surface temperature of washing materials in steam jet process compared with direct boiling process. In terms of the energy and water consumption, the steam jet washing process showed significant savings compared with direct boiling type washing process.

According to development of acu-figure which has been existed in Korea, China and Japan through successive generation and conservation status, I classified the process of manufacture of Standard Acu-Figure that is the first manufactured form in Korea historically. And conclusion was as follows. In history, the first acu-figure was manufactured in Song(宋) Dynasty by Wang Yu Il(王維一). after that acu-figure had been made various type in the each countries. In japan, Cheon Seong Acu-Figure(天聖銅人) was imported and preserved and similar shape acu-figure was manufactured. In Korea, Chim Geum Acu-Statue(鍼金銅像) is unique acu-figure that is conservated and exhibited in museum. Standard Acu-Figure was manufactured after the model of standard human body. First step process of standard acu-figure manufacture undertook at my lab, next step, investigation, discussion, reform was proceeded along with other chief professors major in meridian and acupuncture point.

이 연구는 GIS감리의 특성을 파악하고 기존의 GIS사업에 적용된 감리사례를 분석 하여 실제 적용할 수 있는 GIS감리기준, 지침 및 수행절차와 활동의 정의를 토대로 GIS사업을 효율적으로 추진할 누 있는 표준절차 정의를 통한 GIS감리방법론을 확립 하는데 목적을 두고 있다. 이에 본 인구는 감리수행을 위하며 GIS사업의 표준절차를 정의하고, 이러한 방법론을 준수했는지의 여부를 점검하는 과정을 골격으로 하고 있다. 이를 표준절차 정의에 의한 감리방법이라 하며, GASP(GIS Audit Standard Procedure)방법론이라 한다. GASP방법론이란 GIS감리를 효과적으로 수행하기 위하여 감리대상 사업의 전 공정과 예측되는 대상업무를 도출하기 위한 시범작업(Pilot project)을 수행한 후, 업무에 내한 표준절차를 사전에 정의(Prototype)하여 준수 여부를 감리하는 것을 말한다. 이는 GIS사업의 특성. 범위, 내용을 분석하여 모든 과정의 활동은 평가할 수 있는 보나 발전된 감리방법론이다.

The workgroup of IEEE 802 proposed the IEEE 802.16 standard, also known as WiMAX, to provide broadband wireless access (BWA). The standard specifies two operational modes, one is popular PMP mode, and the other is optional mesh mode. In the mesh mode, the network entry process-NetEntry is the pivotal procedure for mesh network topology formulation and thus, influences the accessibility of whole mesh network. Unfortunately, the NetEntry process suffers from the hidden neighbor problem, in which new neighborship emerges after a new node comes in and results in possible collisions. In this paper, we propose a new SN-protected NetEntry process to address the problem. Simulation results show that the new proposed NetEntry process is more stable compared with the standard-based NetEntry process.

Statistical Process Control(SPC) which uses control charts is widely used to inspect and improve manufacturing process as a effective method. A parametric method is the most common in statistical process control. Shewhart chart was made under the assumption that measurements are independent and normal distribution. In practice, this assumption is often excluded, for example, in case of (equation omitted) chart, when the subgroup sample is small or correlation, it happens that measured data have bias or rejection of the normality test. A bootstrap method can be used in such a situation, which is calculated by resampling procedure without pre-distribution assumption. In this study, applying bootstrap percentile method to (equation omitted) chart, it is compared and evaluated standard process control limit with bootstrap percentile control limit. Also, under the normal and non-normal distributions, where parameter is 0.5, using computer simulation, it is compared standard parametric with bootstrap method which is used to decide process control limits in process quality.

The system engineering should be actively applied to successfully develop a complex and advanced weapon system, because the system engineering uses a multidisciplinary approach. Therefore, this study proposed a system engineering process for a successful weapon system development. According to the national standard policy, an IPT aspect system engineering standard must adapt the ISO/IEC/IEEE 15288. It also asks for tailoring with considering the IPT characteristics as a weapon system acquisition institution. The IPT aspect system engineering process to acquire a weapon system can be expressed with 3 process groups (Agreement, Technical Management, Technical) and 20 processes. There was a need for an institutional framework to hire retired experts from related organizations as consultants to apply the low-cost and high efficiency system engineering in the weapon system acquisition field.
