This paper studies on the necessity of mathematics/statistics in software and hardware fields. First, this research analyzes the contents of mathematics/statistics among subjects in software and hardware fields. Secondly, this research explores the relationship and connectivity between mathematics/statistics and major tracks of software and hardware fields. This connectivity between mathematics/statistics and majors in software and hardware fields would certainly contribute to creating pragmatic and professional knowledge.

In this paper we propose a class of tests for the parallelism of two regression lines based on linear placement statistics. The results of a small-sample Monte Carlo study show that the proposed tests are reasonably good in level control and powers.

Characterizations of probability distributions by different regression conditions on generalized order statistics has attracted the attention of many researchers. We present here, characterization of Pareto and Weibull distributions based on the conditional expectation of generalized order statistics extending the characterization results reported by Jin and Lee (2014). We also present a characterization of the power function distribution based on the conditional expectation of lower generalized order statistics.

We discuss the paper by Cho, Shin, Lee, and Han on the "information-relate" undergraduate statistics major program from the following perspectives: Recently, Korean universities are under re-structuring turmoil. To effectively confront the situation, we need both the vision and the strategy for statistics and statistics departments. For undergraduate statistics major program, our visions are 1) it should not be preliminary education program targeted for the graduate degrees, 2) it should be responsive to future social demand, and 3) it should incorporate the progressive identity of statistics as information and data science. As strategies, we propose 1) the effective integration and due balance among data collection, management and analysis, 2) the harmony and role development of computers and mathematics as statistical tools, 3) the statistics education through task-oriented problem solving, and 4) the emphasis of team work and communication skills.on skills.

The purpose of this study was to raise some questions about the supply and demand statistics of fisheries products and to find implications for food supply and demand. There are three problems in the statistics of fisheries supply and demand. First, it is a structural problem of supply and demand statistics. Supply and demand statistics are not accurate because the feed, the amount of loss, and the waste rate are not surveyed. Second, the amount of fish used as a moist pellet is missing. Third, although some of the seaweed and kelp production is used as abalone feed, it is not classified as feed. Taking these results into consideration, at least 300,000 tons should be classified as feed for fisheries supply and demand statistics. As mentioned above, the current statistics on the supply and demand of fisheries are incomplete and structural improvement is needed.

In this paper, we derive recurrence relations for moments of lower generalized order statistics within a class of doubly truncated distributions. Inverse Weibull, exponentiated Weibull, power function, exponentiated Pareto, exponentiated gamma, generalized exponential, exponentiated log-logistic, generalized inverse Weibull, extended type I generalized logistic, logistic and Gumble distributions are given as illustrative examples. Further, recurrence relations for moments of order statistics and lower record values are obtained as special cases of the lower generalized order statistics, also two theorems for characterizing the general form of distribution based on single moments of lower generalized order statistics are given.

In this paper we compare several statistical packages and propose basic requirements of the package for the efficient education of statistics. We develop a statistical software, KESS, based on Excel. KESS provides all the input menus and output results in Korean.

Statistics was not recognized until the early 20th century as an independent science, and statistical education research came to an international milestone in the late 1940s. The purpose of this study is to investigate the historical development of statistics education research, focusing on the activities of the International Statistical Institute (ISI) and the International Association for Statistical Education (IASE). Statistics education in Korea is considered with regard to the history of international research on statistics education in this study. It implies for the direction of statistical education research to domestic mathematics education researchers and statistical researchers related to statistical education research.

Mathematics develops the ability to solve a problem and the spirit of inquiry by logical thinking, and statistics develops the ability to making a decision scientifically or rationally by various data processing techniques. Even though mathematics is a compulsory subject in most of IT-related departments, the reality of Korean education is serious. This research studies on the necessity of mathematics/statistics education for a person studying IT and analyzes the contents of mathematics/statistics among IT-related subjects. And the research makes a plan for specializing IT-related departments by use of specialized education programs using mathematics/statistics and examines a development plan in the short or long term period for connectivity with mathematics/statistics fields. This connectivity between IT-related departments and mathematics/statistics in the 21st century would certainly contribute to creating more practical or technical knowledge.
