The relative importance of single-shot kill probabilities, rates of fire, weapon allocation strategies, and the size of initial force in warfare between two force with heterogeneous multiple weapon systems are considered by examining their effect on a natural measure of effectiveness, the expected number of survivors. Attrition equations are derived via stochastic formulation to represent the mean course of battle having an underlying probability distribution. It is assumed that each side uses indirect area fires. Level of intelligence activities are reflected in the availability of spontaneous information on the current enemy status. Depending on the availability of the information on the current enemy status, each participatory unit may follow 1) a prescribed attack pattern (fraction of the available units assigned to various enemy targets) or 2) an adaptive attack pattern depending on the enemy status at that time. Conditions for possible stalemate are discussed.

Pancreatic cancer is a fatal malignancies which is predominantly seen in men and at advanced age (40-85 years) and has an aggressive course. Its frequency is gradually increasing over the past years. It accounts for 2% of all cancers and 5% of cancer-related deaths. Pancreatic cancer takes the first place among asymptomatic cancers. Ninety percent of cases are adenocarcinomas. Ten percent of the patients have a familial disposition. The disease is very difficult to detect as it has no early signs and spreads rapidly to surrounding organs is one of the most deadly types of cancer. Pancreatic cancer may result from hereditary germline or somatic acquired mutations in cancer-related genes and mutations also cause cancer progression and metastasis.

I have already reported about the necessity of international cooperation, our role and measures under the present conditions of private technological exchange in the Japanese and Korean Consulting Engineers Meeting at Taejeon, Korea. Continuously I have been discussing whether we, Japanese ＆ Korean consulting engineers can give technological cooperation and support with the regard to industrial technological development, enhancement of industrial infrastructure, social and economic development. I am focusing on Vietnam which has been in the course of economic development to excess in a sense and this country attracts the world's attention. I probe the possibility of technological cooperation under the cooperation of Japanese & Korean consulting engineers while I introduce the present conditions of Vietnam. In addition Vietnam has become a member of ASEAN officially, and the foreign investment in Vietnam has gotten on the right track. Moreover, the regularization of lawsystem in Vietnam is well under way and they aim at joining advanced nations in the 21st century.

Even though there are extracurricular mathematics classes for gifted students in all levels of schools in Korea, teachers cannot conduct the classes properly because the contents of the textbook are not adequate for the purpose of the classes. So, what they tend to do in the classes is just drilling with many problems which have already shown up at university entrance examinations and various mathematics competitions. The purpose of this paper is to give an example of what the content should be in "Mathematics III" (an elective subject for the science high school students according to the fifth and sixth amendment of national curriculum) and to suggest how to design the extracurricular classes for gifted students. Extracurricular classes of the ordinary secondary school as well as the elective course for the science high school can be suitably designed with choices of topics in the contents of Mathematics III.

In order to cope with improvement of labor cost and cargo volume, Korean ports, especially Busan port, are in need of many new facilities. Of course, current facilities should be fully used, and at the same time it needs to make every effort to maximize its productivity as well as cost saving. To this end, this study has decided to focus on automatic yard operation suitable to the domestic container terminal environments, making a survey of many advanced container terminals, trying to find out their common factors, and finally suggesting several alternatives based on the combination of these factors. Also, this study has suggested the present value of initial investment and operating cost by alternative, and at the same time presented the relationship between cargo handling volume and cost/revenue of the optimal alternative, so that it may be of help in decision making.

A technology for inevitable integration as well as an ability of development of technology according to professional fields is needed and supported for securing technology in the era of international competition. In other words, advanced business technique and technology applied for streamlining of management are required and the relations between operations and systems could be clarified. This paper reviews the course for development of process used in the systems engineering and business administration and tries to seek the way of training professionals in a variety of fields for elevating domestic technologies in different fields to the international level. Particularly, it tries to get the way of overcome the present technical restriction that depends on imports through matching a hazard analysis method with the method above mentioned. Especially, it tries to present the way of contributing to securing software safety on the basis of the importance of development of process model that takes the life cycle into consideration.

The purpose of this study was to develop a pragmatic fashion internship program as a following study of 'An analysis of the consciousness of the professors and college students for the fashion industry internship'. The methods of the quantitative analysis and some case studies were used for this study. The results of this study were as follows : Internship program has 6 steps ; ready, introduction, selection, operation, reputation, management. It will help professors and college students to execute the program systematically. The contents of the fashion internship program model for professors were as follows: 8 recruiting methods to find internship companies, the contents of the internship agreement, 6 types of internship, the contents of the recommendation letter, advanced education contents for a fashion internship, e-mentoring program model, a curriculum of the cultural study and the major course, evaluation standard elements of the intern students, the methods of evaluation etc.

AC generator plays an important role of power system. The large AC generator fault may lead to large impacts or perturbations in power system. And then the protection of a generator has very important role in maintaining stability in a power system. In present, the DFT(discrete Fourier transform) based RDR(ratio differential relay) had been widely applied to a internal fault of a generator stator winding. But DFT has a serious drawback. In the course of transforming a target signal to frequency domain, time information is lost. DWT uses a time-scale region. This paper proposes an advanced fault detection algorithm using DWT(discrete Wavelet transform) to enhance the drawback of conventional DFT based relaying. To evaluate the performance of the proposed relaying, we used the test data which were sampled with 720 [Hz] per cycle and obtained from ATP(alternative transient program) simulation. And we made a comparative study of conventional DFT based RDR and the proposed relaying.

The undergraduate structure based on flip learning should be a necessary course to cultivate value creation capability based on students' problem solving capability through the change of university education in the fourth industrial revolution era. Introduction and spread of Flipping Learning combining project-based learning with MOOC is requied. As the introduction and spread of AI-based learning consulting (E-Advisor), which is becoming increasingly advanced, the transition to "personalized education" that meets the 4th Industrial Revolution should be made.
