In this paper, we develop scheduling system under MTO (Make-To-Order) Production and implement it to real application. Generally, scheduling system is regarded as company specific problem such that the required business logic might be different within a same industry. The differences are caused by different constraints of each company requirements. Company specific algorithms are commonly employed using rule-base or heuristic procedure. Based on these characteristics, heuristic procedure are developed and implemented for developing MES (manufacturing execution system). The proposed approach are applied to real industry and proved as an efficient approach in terms of practical views.

The purpose of this study was to obtain the materials on the posture education at school. The subjects chosen for this study were 240 children from the first to the sixth grades at the elementary schools located in Seoul and Kyong-Gi Province. The children were interviewed each to examine the posture structure, were measured the degrees of vertebrae curvatures and the structure of the lower limbs by the Cureton's conformatuer to find the characteristics of the posture. The results were: (1) The children were near to the type of ectomorph posture. About 28% of the children had previously suffered the serious diseases. The children of unbalanced diet were from 50% to 60% of the total number. (2) 45% of the children used the desks and chairs when they study, and 70% of them had their desks and chairs unfit to their body structures. (3) Under these unfavorable circumstances, the children showed, however, the higher enthusiasm for the posture education which is encouraging. (4) The average Angle ∠α of forward curvature in standing position was about -4˚∼+5˚ among boys and -3˚∼43˚ among girls. (5) The average angle ∠a' of verabrae curvature of the thoracic was 3˚∼12˚ among sboy and 4˚∼12˚ among girls. (6) The male with Kyphosis (hunch back) was about 155˚∼168˚, the female was 152˚∼166˚. The male and female with lordossis of lumber curvature was 152˚∼168˚. (7) The children of bowlegs (O type) and those of knock knees (x type) were 3% of the whole.

정후민,신윤권,조상복,이종화 울산대학교 2001 공학연구논문집 Vol.32 No.2

압저항형 스마트 실리콘 압력 센서를 0.6 ㎛ 이중 폴리 실리콘 이중 금속 CMOS 공정으로 구현하기 위하여 설계하였다. 이 스마트 실리콘 압력 센서는 압저항형 저항기들로 된 휘스톤 브리지를 갖는 다이아프램과 op-amp, A/D 변환기, 및 UART 회로 등의 주변회로 들로 구성되어 있다. 브리지 회로의 출력 전압과 압력에 의한 기계적 응력 사이의 관계를 COSMOS-M 상용프로그램으로 다이아프램의 응력 분포를 모의실험하여, 압저항기의 최적의 위치와 크기에 대한 연구를 하였다. CMOS op-amp 회로는 규정된 출력 특성을 얻기 위하여 크기가 다른 트랜지스터들로 설계하여 HSPICE로 모의실험하여 최적화 시켰다. A/D 변화기 회로는 가능한 칩 면적을 줄이기 위하여 서브 레인징 기법과 신경 MOSFET 구조를 이용하여 설계하였다. UART회로는 VHDL 소스 코드와 셀 라이브러리를 이용하고 Synopsys로 합성하여 설계하였다. 회로의 물리적 레이아우트 설계는 Mentor 틀로 설계하였다. 그러나 온도보상회로와 출력오프셋 문제는 아직 해결하지 못하고 다음에 연구할 예정이다. A piezoresistive smart silicon pressure sensor is designed to implement with 0.6 ㎛ double-polysilicon double-metal CMOS precess. This smart pressure sensor is composed of a diaphragm with piezoresistive resistors' Wheatstone bridge and the peripheral circuitry of op-amp, A/D converter and UART. The relationship between the output voltage of the bridge circuit and the mechanical stress by applied pressure was studied by simulating the stress distribution on the diaphragm with COSMOS-M package program to optimize the size and position of piezoresistors. The CMOS op-amp circuit was designed with different CMOS transistor sizes to obtain the defined op-amp output characteristics and simulated with HSPICE. The A/D converter was designed using neuron MOSFET structure and sub-ranging method to minimize the chip area. The UART circuit was designed by using VHDL source code and cell library and by synthesizing with Synopses and the physical layout of the circuit was designed with Mentor tools. The problems for temperature compensation and the output voltage offset were not yet considered.

A study for the model of the laboratory experiment curriculum in teacher's college seience was done. Because of individual characteristics in each field in department sc-ience education, the model was not necessarily unique. However, the common elements of frame in this model were suggested as follows : 1. The ratio of laboratory experiment's credits and total major credits. 2. The ratio of basic common laboratory experiment's credits (basic physics, basic chemistry, basic biology, and basic earth science) and total laboratory experiment's credits. 3. Credits and course name of laboratory experiments charactoristic for the science education in teacher's college. 4. Suggestion of the experimental guide for an inquiry learning.

It has been brought to our attention that there has been an increase in the number of large scale constructions on sites where damages from sea wind(or water) are noted. The problem with these particular structures are that they are likely to be targets for invasions by chloride. This experiment is to study diffusion of chloride ions within the concrete, and corrosion of reinforced concrete as a result of its spread. In order to find out the slip characteristics of chloride ions and reinforced concrete, MIDAS and ABAQUS, among several other commercial structural analysis program, were deployed in the study.

需要가 減少하는 減損性 製品에 대한 在庫 體系의 模型 設定에 관한 硏究

In the previous studies on Inventory System for deteriorating items, it is assumed that the demand rate is constant and is independent of time during a period of each cycle. However, the assumption is unrealistic because the demand rate is influenced by the price and time. The purpose of this study is to determine optimal ordering quantity and optimal selling price which maximize profit. In this study, it is assumed that the demand rate is governed by the price and time and that replenishment orders are placed at equal intervals in a finite time horizon. A numerical example is used to illustrate the proposed model. A sensitivity analysis to v(parameter of the deterioration rate function), and α(constant representing the decreasing rate of the demand rate ) is also performed. The results of sensitivity analysis show that the optimal selling price increases gradually when v is increased with fixed α. while the optimal ordering quantity decreases with increasing α and fixed v.

Objectives Mindfulness-base cognitive therapy (MBCT) has been used to treat patients with depression to prevent relapse. The purpose of this study was to examine the effectiveness of Mindfulness-Base Cognitive Therapy for patients who suffer with generalized anxiety disorder or panic disorder for 1 year. Methods 19 patients with generalized anxiety disorder or panic disorder were assigned to receive MBCT for a period of 8 weeks. The Hamiltion Anxiety Rating Scale (HAM-A), the Hamilton Depression Rating Scale (HAM-D), the Beck Anxiety Inventory (BAI) and the Beck Depression inventory (BDI) were used at 0 weeks, 8 weeks and 1 year to assess the results. Results MBCT demonstrated significantly decreases on all the anxiety scale scores (HAM-A, p=0.00 ; BAI, p=0.00) and depressive scale scores (HAM-D, p=0.99 ; BDI, p=0.00). The patients who received 8-week of MBCT showed a higher remission rate (15/19, 78%) during the 1-year follow-up period. Conclusion MBCT may be effective at relieving the anxiety and depressive symptoms of patients who suffer with generalzed anxiety disorder or panic disorder for 1 year. However, further well-designed controlled trials are needed to assess the value of MBCT.
