This research is to comprehensively evaluate offensive abilities of baseball players who are expected to produce as many runs as possible by their hitting and running. To this end, we establish a simulation program to obtain the so-called scoring index of an individual player. The scoring index of a player is defined as an expected number of runs scored by an imaginary team that is composed of nine copies of the player. As a simulation input, we use 2014 season data of Korean pro-baseball. As a result, we present the scoring indices of top 10 players, 9 Korean pro-baseball teams, and overall 2014 season. The scoring index can serve as a comprehensive evaluation of offensive ability of a player or a team, selection of players for a (national) team or for a starting line-up, estimation of player's worth, and so on.

The purpose of this study is to investigate the variable factors influencing children's interpersonal relationship skills and analyze the effects of marital perspective-taking ability, managing responses of young children and emotional intelligence on the interpersonal relationship skills of children. The study subjects were young children aged from four to seven attending private kindergartens or public day care centers in Seoul or Kyeongki-do and their mothers. The results are as follows : 1) First, marital perspective-taking abilities were indicated higher on boys than girls, children in a full-day program than those in a half-day program, university graduates or higher degree holders than collage graduates, single-income families than double-income families. In case of managing responses of young children, boys showed high avoidance of offensive disposition and girls showed high emotions dissipation. Also, young children in a full-day program showed non-responses on managing responses but high responses on emotions dissipation, and children of mothers with bachelor's degree or higher education showed support and children from double-income family showed no responses in high. Moreover, emotional intelligence of young children in a full-day program was higher than that of children in a half-day program, interpersonal relationship skills were showed higher on girls than boys, half-day children than full-day ones, children from single-income family than those from double-income family. 2) Meaningful relationships were indicated between these variables; managing responses of young children, emotional intelligence and interpersonal relationship skills by partly showing correlations. 3) Children in a half-day program with low in emotions dissipation, non-responses, offensive dispositional managing responses but high on Avoid, emotional intelligence showed high interpersonal relationship skills.

One of the considerations in weapon systems procurement is the objective of maximizing the current force. Also, offensive effects, rather than defense are valued in weapons system development and procurement. Especially, the survivability of a naval ship is equally important as the offensive effect of onboard weapons. In case of naval ships, development of attack tactics and research regarding damage minimization must be conducted through live fire exercise against actual targets in order to minimize damage from the enemy. However, it is difficult to conduct such adequate measures due to realistic limitations such as time and budget in order to verify and calculate a weapon system's attack and damage effects along with the lack of practical studies in this subject despite numerous interests. Research are being conducted utilizing M&S to estimate attack effects and study damages due to such reason, but the lack of authoritative data and development ability are limiting calculation of reliable results. Therefore, this study will propose a measure to increase survivability of a weapon system(ship/vessel) utilizing research of vulnerability from enemy attacks analysis method against a naval ship(Craft Air Cushion).

The purpose of this study is to present the direction of development of our navy's response strategy through analysis at the ends, ways, and means level of the Chinese navy's offensive strategy for the West Sea. As a result of the analysis, at the ends level, the Chinese Navy's offensive strategy for the West Sea strategy is being linked to a grand strategy to protect maritime rights and achieve maritime power between the U.S. and China competition, at the ways level, the Chinese Navy is expected to create a foundation for the international community to recognize the West Sea as China's inland sea through "routine entry" and "exercise authority", and in case of emergency, it will try to secure sea control in the West Sea in a short period of time by blocking Korea's maritime transportation route based on the overwhelming preemptive attack capability of aircraft carriers. At the means level, it is accelerating the construction of aircraft carrier warfare units and improving its ability to engage long-range missiles. As a direction of development of the Korean Navy's response strategy in response to this, first, Establishment and Development of National Maritime Security Strategy in conjunction with the Korean Indo-Pacific Strategy. Second, it proposes the development of the concept of effective security operations for the east sea area of the West Sea intermediate line, and third, the development of the concept of combat performance and capacity building to strengthen survival and lethality.

The CF(Counter-fire) is neutralizing enemy's all command control systems and fire support elements. It will weaken a battle continuous ability and an intension to fight. At the beginning of the CF is obtaining locations of targets using various detection assets. CF command center processes acquired target information and send it to attacking equipments. The targets are classified into two classes, preplanned target and target of opportunity The target of opportunity is potential threaten, so it needs to take a immediate and exact process for determining location of target of opportunity. This paper proposes the real-time processing algorithm for offensive weapons to strike target of opportunity, and presents the result of its performance.

The joint warfighting environment, arranged by the net work-centrics, consists, with the situational awareness, the battlespace deconfliction, the joint force ID/location/allocation, and the ordnance on targets, considered by the concepts evolving In meet the future scenarios and threats. And then, the next generation warships have the operational requirements, such as the major offensive capability, the low operating cost, the ability to operate in net. centric forces, the revolutionary stealth, the in-stride mine avoidance, and the revolutionary manning. Therefore, the proposal discussed at this paper will be accepted in order to resolve only the portion of the afore-mentioned problems.

In baseball, sabermetric batting statistics are used to compare an offensive performance of players. There exist dozens of sabermetric statistics, but baseball fans don't like the complexity of an abundance of measures. This paper provides a batting grade index (BGI) using principal component based on eight batting statistics. These are OPS, ISO, SECA, TA, RC, RC/27, wOBA and XR. We show that how standardized batting statistics are aggregated and weighted to arrive at a single composite measure of BGI. Also our result allows for segmentation of players into groups using the K-means clustering algorithm.

The future battlefield operation concept does not focus on advanced and complete weapon systems, but requires a new battlefield operation concept that can effectively demonstrate offensive power by combining a large number of low-cost, miniaturized weapons. Recently, research on the autonomous application of major technologies that make up the mission control system is actively underway. However, since the mission control system is still dependent on the operator's operating ability when operating multiple robots, there are limitations to simply applying the automation technology of the existing mission control system. Therefore, we understand how changes in operator capabilities affect multi-robot operation and propose an adaptive mission control architecture design method that supports multi-robot integrated operation by adjusting the level of autonomy of the mission control system according to changes in operator capability.
