The artificial intelligence software market is expected to grow sixfold from 2020 to 2025. However, the software development process is not standardized and there is no standard for calculating the cost. Accordingly, each AI software development company calculates the input man-hours according to their respective development procedures and presents this as the basis for the development cost. In this study, the development stage of "artificial intelligence-based software" that learns with a large amount of data and derives and applies an algorithm was defined, and the required labor was collected by conducting a survey on the number of man-hours required for each development stage targeting developers. Correlation analysis and regression analysis were performed between the collected man-hours for each development stage, and a model for predicting the man-hours for each development stage was derived. As a result of testing the model, it showed an accuracy of 92% compared to the collected airborne effort. The man-hour prediction model proposed in this study is expected to be a tool that can be used simply for estimating man-hours and costs.

Accurate software effort estimation has always been a challenge for the software industrial and academic software engineering communities. Many studies have focused on effort estimation methods to improve the estimation accuracy of software effort. Although data quality is one of important factors for accurate effort estimation, most of the work has not considered it. In this paper, we investigate the influence of outlier elimination on the accuracy of software effort estimation through empirical studies applying two outlier elimination methods(Least trimmed square regression and K-means clustering) and three effort estimation methods(Least squares regression, Neural network and Bayesian network) associatively. The empirical studies are performed using two industry data sets(the ISBSG Release 9 and the Bank data set which consists of the project data collected from a bank in Korea) with or without outlier elimination.

Use Case Point(UCP) is a measure of a software project size for software effort estimation based on use case. UCP measures the size of the software project based on the use case model. Because UCP is based on the use case model, it is intuitive and easy to obtain. Also, it does not require extra artifacts. On the other hand, UCP has some problems. UCP assumes every transaction has the same complexity. But, the number of operations and complexity of operations may affect complexity of transaction. In addition, UCP uses simple rating scale of complexity, but it may be inadequate for detailed estimates. To solve these problems, we suggest "Transaction Point(TP)", a size measure based on use case transaction. TP considers actors and operations in transaction. Complexity of transaction is based on the number of operations and complexity of operation, so it can support detailed estimation.

The value of Karatedo as security guard martial art can be categorized like following in connection with this point. The first one is value of defensive measure. It can raise dispassionate of dangerous condition by exact and dispassionate judgment and quick movement and it can raise capability being able to overpower opponent by exact judgment and quick action at incident. Secondly, it is physical value. The third one is psychological value. The forth one is technological value. The fifth value is education. The last one is value as martial art. Karatedo is martial art of noble man starting from proprieties and ending to proprieties. It include ethical aspects including proprietis, technology of 'Ilgekfilsal' being able to kill life and survive life.

As a way to popularize Karatedo, a curriculum for developing excellent trainers is needed. For that, DACUM was used to specifically look into the field of duty and work that a Karatedo trainer should have, and the purpose of this study is to present fundamental data necessary for developing and organizing the curriculum of cultivating Karatedo and create a useful material that can contribute to improve Karatedo trainers' performances who are working on site. A survey using Likert scale's 7 stages was conducted on DACUM meeting data, 28 managers and 108 trainers. Based on the collected data, this study had a test in order to solve the presented subject using DACUM method and SPSS WIN Ver. 14.0. This core work through the requirements analysis process. And karate leaders the necessary knowledge, skills, and tools, and attitude analysis was carried out to perform the tasks of each. Knowledge, skills, tools and attitude for each task, toward the results of the analysis were 47 core tasks. 167 knowledge items, function 143 items, the tool 60 items, 16 attitude items reclassified a total of 18 subjects were derived. The configuration of the karate leader training program curriculum model 'Karate practical expert area', 'theory karate expert area', 'Karate gym business area experts' was composed. Basic process of how it works Step 1, Step 2 integration process, replenishment process intensified Step 3 was composed.

The leisure boat industry has the potential to become a high-value-added industry in the future. Recently, a study on Korean high-speed leisure boats for fishing was conducted. This study suggests a product configuration model-based shipbuilding cost estimation method for determining the type of leisure boat suitable for mass production, as part of a research for productivity improvement. The suggested estimation method based on the analysis of the leisure boat process and generic YWBS can calculate quantitative and concrete data. By using this method, the cost of building the catamaran-type design ship can be reduced by 17 times, compared to that of the monohull-type mother ship. This implies that the final design of the Korean high-speed leisure boat for fishing will have a competitive price at the actual production stage.

The purpose of the research is to let people recognize the necessity of Karatedo training and enhance the value of it. Karate sparring is quite helpful to learn the skills that how to escort a protectee as a guard. The skills are divided into hand skills, foot skills and pitching skills. Firstly, it is the hand skills. 'ap-son-chi-gi' or 'di-son-chi-gi' at pressure points such as face, neck and abdomen is effective to overpower adversary. If straight attacks are not easy, 'return stroke' is better. Secondly, it is the foot skills. Front kick towards pressure points, straight attacks like side kick and hindpaw kick and curving attacks like front-spinning kick, 'ap-hu-ri-gi and 'di-hu-ri-gi', these are different types of the foot skills. Lastly, it is the pitching skills. To overpower compeletly, tripping up and 'hu-ri-gi' for breaking the balance and then hand and foot skills for attacking the pressure points are the best way.

발파진동에 영향을 미치는 여러 매개변수들 중에서 현재 발파진동 예상식을 도출하기 위해 장약량과 거리를 매개변수로 하여 발파진동을 예측하고 있다. 여기에 사용되는 장약랑은 지발당 최대장약량으로, 발파당 장약량과의 관계는 언급하고있지 않다. 따라서 본 연구에서는 지발당 최대장약량이 동일한 상태에서 발파공수를 변화시키는 방법으로 발파당 장약량이 변화할 때 발파진동속도의 변화를 비교·분석하였다. 발파공수를 5공에서 10공까지 변화시 켜가며 발파진동을 폭정하고 분석한 결과 지발당 장약량이 동일함에도 불구하고 공수가 증가함에 따라 환산거리 60∼90 구간에서 진동속도가 높게 측정되었다

현재의 소프트웨어는 매우 크고 복잡하다. 고품질 소프트웨어는 요구사항 단계부터 정확하게 분석해야 한다. 그러나 자연어 요구사항은 부정확하기 때문에 유스케이스 식별이 어렵다. 게다가, 기존 요구 사항 분석 방법은 객체와 용어 식별에 대한 정확한 기준이 없다. 따라서 분석 결과는 분석가마다 다르다. 본 논문에서는 자연어 요구사항으로부터 유스케이스 추출 및 소프트웨어 공수 산정 방법을 제안한다. 제안한 방법에서는 Goal Modeling과 Fillmore의 Case 메커니즘을 개선했다. 이 방법은 자연어 요구 사항을 단계별로 분석하여 유스케이스를 모델링한다. 또한 유스케이스 점수(Use Case Point)를 이용하여 소프트웨어의 공수를 산정(Effort Estimation)한다. 제안한 방법은 고품질 소프트웨어 개발을 위해 자연어 요구사항의 변경 없이 유스케이스 추출이 가능하다. 또한 추출된 유스케이스를 통해 UCP 기반의 공수 산정을 평가할 수 있다. 본 논문에서는 우체국 시스템의 사례에 적용하였다.
