This study developed the planning process for technical management of engineering project applying systems engineering process in order to correctly design technical management activities early during the system development projects. The developed process describes a systemic design process of a product to be developed as well as the development process and the personnel team of project organization. As an outcome of the process implemented by a Model-Based Systems Engineering(MBSE) software, a systems engineering management plan(SEMP) and a risk management plan can easily be produced.

This study presents the new dispatching rules of job shop scheduling with unbalanced machine workloads to decrease mean flow time and mean tardiness. The proposed dispatching rules consider the information related to work remaining, modified job due dates, modified operation due dates and machine workload. The performance of the new dispatching rules is compared and analyzed with the existing rules through the computer simulation at different levels of workload imbalanced. The results can be useful to the researchers and practitioners of job shop scheduling with unbalanced machine workloads.

This paper deals with the problem of scheduling jobs and rate-modifying activities on parallel machines, motivated by a problem commonly found in the surface-mount technology of electronic assembly lines. A rate-modifying activity involving repair, maintenance and readjust is an activity that changes the production rate of equipment under consideration. In this paper, the processing time of a job scheduled before the activity is equal in each parallel machines. On the other hand, if the job is scheduled after the rate-modifying activity than the process time depends on the modifying rate of the activity. Our purpose is to schedule the rate-modifying activities and jobs to minimize the makespan on parallel machines which is NP-hard. We propose a branch and bound algorithm to solve medium size problems optimally. Also we develop three heuristics, Modified Longest Processing Time (MLPT), MULTIFIT and COMBINE algorithms to solve large size problems.

The main objective of this paper is to search whether containment vessel's best pressure may increase until how long when loss of coolant accident (LOCA) happened in containment vessel of Ulchin nuclear power plant 1 and 2. Another goal of this research is to find the influential factors that increase containment vessel pressure. Model for this research is Ulchin nuclear power plant 1 with 10 cycles. Data were collected by simulator of Ulchin nuclear power plant 1 and design of experiment was used for data analysis. For the experiment, seven factors that are going to influence in containment vessel pressure were chosen. It was found that fatter which influences in early rise of containment vessel pressure after LOCA is only explosion size. Also, containment vessel's best pressure (3.74 bar.a) was much lower than limit (4.86 bar.a) of FSAR (Final Safety Analysis Report).

This study relates to the architectural planning principle of Gyeonghoeru pavilion, one of the major buildings in Gyeongbokgung palace. The study is concentrated on The Book of Gyeonghoeru Pavilion written by Jeong Haksun in 1865 during the reconstruction of Gyeonghoeru pavilion. The architectural planning principle of Gyeonghoeru pavilion disclosed in The Book of Gyeonghoeru Pavilion appears to be 'the method of expanding with six by six system'. 'The method of expanding with six by six system' means a way of continuously extending the number related to 6 by addition, subtraction, multiplication and division, and reflecting to architecture, having number 6 as the basic number. Number 6 means a large amount of water in East Asian philosophy, Applying 'the method of expanding with six by six system' to the architecture of Gyeonghoeru includes an intention to prevent fire in a way of a type of incantation because Korean traditional wooden buildings are we to fire. Since Gyeonghoeru is surrounded by a pond and was constructed based on the number 6 having a strength of water, it was believed that it could be safe from fire. This study compares the contents disclosed in The Book of Gyeonghoeru Pavilion with the construction of Gyeonghoeru to find out how the number 6 was applied to the overall construction of Gyeonghoeru. From the fact that the total number of km of Gyeonghoeru is 36 ($6{\times}6$), the number of pillars is 42 ($6{\times}7$), and the number of windows and doors is multiples of 6, it has been found out that the number 6 is deeply related to the overall construction of Gyeonghoeru. In addition to the fact that the construction of Gyeonghoeru can be explained by 'the method of expanding with six by six system', The Book of Gyeonghoeru Pavilion also discloses parts where Diagram of Hotu, Later Heaven Arrangement and Arrangement of 64 Hexagrams are applied. Therefrom, it has been found out that Gyeonghoeru pavilion was constructed by applying the principles of East Asian philosophy based on The Book of Changes.

A study is for the approach that we could reduce the logistics costs through uprising the efficiency, complying to the demand in time, stock management based on the general production plan in the point of SCM. We will take following steps to get the goal. First, we will overview the physical distribution expenses annually. Second, will find the main cause of optimal load loss by improper container and lack of delivery flexibility to the demand. Third, the goal will be inferred through the fast information share based on organic relationship, the establishment of general production plan, the improvement of stock management plan. By way of this process, it can be accomplished expense reduction as well as flexible establishment of the reduction of worker's load.

As today's business environment becomes more globalized and distributed, the importance of collaboration is rapidly increasing. This paper presents a systematic approach to collaboration strategy planning. The framework suggests a Collaborative Process Map need to be identified. Then, Collaboration Maturity of each area is evaluated. Based on the Collaborative Process Map and Collaboration Maturity Evaluation, Collaboration Execution Plans are established. A case study of semiconductor industry is also provided.

The purpose of this paper is the study on the piazza plan of basilica S. Pietro. The results of study are as follows: 1. The piazza of the basilica S. Pietro was planned in relation to building-piazza-symbol of interior piazza-street as city planning characteristic of Baroque and architectural characteristic of elliptical piazza form. 2. The function of piazza of basilica S. Pietro was planned for religious meeting of a grand scale than a piazza for the common run of people. 3. In general, the disposition, ground, elevation and section plan of the piazza of basilica S. Pietro was planned by principle of spatial and formal composition, according to axis, symmetry, proportion, division and contrast. 4. The location, scale, shape of piazza for disposition and ground plan of the piazza of basilica S. Pietro was basically decided by not only elements of Basilica building, Vatican Palace, Street and Walls of surroundings with axis of the Basilica building, but Fountain and Obelisk as existing constituent elements. 5. The elevation of the piazza of basilica S. Pietro was composed of boundary that was enclosed from wall of trapezoid piazza and gallery of elliptical piazza with equal height as symmetry. And the section plan was planned to approach into the Basilica through slope and stairs of gentle angle, utilizing of existing land form.
