Today's environment of enterprise is changing, They have to face customer' demands with the right product, the right service and supply them at the right time. And also cut down logistics and inventory cost and bring up the profit as much as they can. This means the change of putting enterprise first in importance to putting customer first importance. therefore to correspond to customer's demand, shorting lead time is becoming a essential condition. The answer to this changes of environment is supply chain management. In this paper, It consolidates the necessity on a LTV(Life Time Value) and analyzes data which is concerned of Customer Value. Under the these environments, defines the LTV(Life Time Value) rule that can improve the customer value. We solved this problems using AHP(Analytic Hierarchy Process) for consistency at relationship matrix, AHP(Analytic Hierarchy Process) is based on Saaty's consistency rate. If consistency rate is under 0.1 point, preference rate's weights are acceptable. This study develop a program for AHP weights and support Satty's consistency rate.

A Study on the Curtain Wall parts that appear to cause problems and to improve information exchange system by applying the model of SOA-based development directions are suggested. Availability of the IT industry than other industries that have closed in the field of construction such as SOA. IT systems for the compatibility of the information being sought may be applied. In the future adoption of SOA and Web service-based approach to information exchange with suppliers and improving the efficiency of information for the construction to cover the entire field of research will be conducted as a SOA system.

현대의 모든 기기나 사물들은 인터넷과 연결이 되어 있어서 직접 조작을 하지 않아도 원격으로 쉽게 사물들을 조작할 수 있고, 사물들이 스스로 필요한 것들을 확인하여 사용자에게 알려주는 시대가 되었다. 사용자 생활면에서는 편리한 시대가 되었다고 볼 수 있다 하지만 보안면 에서는 나쁜 의도를 가진 사용자들에게는 좋은 먹잇감이 되었다. 이 논문에서는 해킹을 시도하거나 다른 사람에게 손해를 끼치려는 사람들을 방지하기 위해 블록체인의 보안 기술을 이용하여 IOT의 보안 기능을 향상하는 논문을 작성하려고 한다.

Food consumption patterns are predictors of nutritional status at all age levels and vary among and between different age groups. This study was designed to asses food habits and fast food eating patterns of college students in Ulsan area through questionnaries. Data from 330 useable forms was analyzed for percent differences, frequency of consumption, and statistical significance of differences between male and female students (T-test and chi square methods were utilized). Food habit score of female students was significantly higher than of male students. The reason for using fast food chain was 'convenience' or 'good taste'. The most preferred food by subjects was noodle or dumpling and least preferred food was pizza. In general, they had a higher satisfaction scores in taste and service of fast food and lower scores in amount and price of it. From this results it appears there is a need for developing domestic brand fast food to lower the price of fast food and giving the nutrition education for proper food selections and eating patterns.

최근 들어 한국디지털위성방송사가 위성을 통한 디지털 방송을 통해서 양방향 서비스를 본격적으로 시작하면서 디지털 TV 가 방송통신 융합의 총아로 등장하고 있다. 그러나 방송사업자가 디지털 방송으로 전환하고 양방향 서비스를 제공하기 위해서는 막대한 비용의 소요되므로 이에 대한 재원을 마련하기 위해서 방송사업자들은 양방향 서비스를 통한 수익 비즈니스 모델을 발굴하는데 고심을 하고 있다. 또한 통신사업자들은 디지털 TV 서비스 시대의 새로운 주자로 등장하면서 기존에 전통적으로 수익을 올렸던 영역에서 벗어나 방송과 통신을 융합한 새로운 영역에서 방송사업자와 경쟁하여 직접적으로 소비자들을 상대로 수익을 올리는 방법을 연구하고 있다. 따라서 양방향 TV의 비즈니스 영역이 무엇이며 그 영역 내에서 주요 부분을 차지하고 있는 T-commerce 의 가치사슬과 주요 주자들의 구성에 대해서 연구하는 것은 중요하다.

The paper surveys various analytical models for IEEE 802.11 medium access control protocols and critically discusses recent issues developing in wireless mobile ad hoc networks and their MACs. The surveyed MAC protocols include the standard IEEE 802.11 MAC suites such as IEEE 802.11 DCF, IEEE 802.11 PCF, IEEE 802.11e EDCA, and IEEE 802.11 ad hoc mode; and also the newer, de facto MAC protocols. We study the analytic models of the standard MAC suites followed by the newer analytic models that have been published in recent years. Also, the paper tries to include most of current literatures discussing analytic modeling of MAC in conjunction to some critical issues such as contention among ad hoc nodes, hidden terminal problems, and real-time service support.

블록체인 기술이 발전함에 따라 블록체인을 기반으로 하는 웹 서비스가 기획되고자 할 때, 데이터 저장에 대해서 무결성과 기밀성 유지, 데이터의 크기 등의 문제가 발생할 수 있다. 따라서 서비스에 내에서 사용되는 다양한 데이터의 각 특성에 따라 저장소를 선택하여야 한다. 블록체인 기반 웹 서비스의 유형을 분류하고, 서비스에서 사용되는 데이터를 분류할 수 있도록 데이터 분류 체계도와 그 과정에 대해 제안한다. 이를 통해 블록체인 기반 웹 서비스에서 블록체인과 외부 저장소 혼용의 효율 상승을 기대한다.

Currently, there is a wave of second startup companies in Korea as well as within the global market, and the role of accelerators have become highly important at the center of changes. In the early 2000s, Y-Combinator has made Airbnb and Dropbox grow into a global company, and its start-up support model has begun to gain worldwide attention, and further became the beginning of the "accelerator" industry. The accelerator industry has been expanding rapidly throughout the United States, Britain and Israel, as well as China and Southeast Asia in recent years. As of the end of 2018, more than 130 accelerators have been operating in Korea, starting with Primer in 2010, and the scope of its activities has been expanding into specialty fields such as Pintech, bio industry, and Block chain, as well as Game. The purpose of this study is to study the role of the accelerator through the phenomenon of these accelerators and their step-by-step support services.

Integrated Supply Chain Management is a important subject for all enterprise activities as include logistics/sales, transfer and storage, manufacturing, purchasing of materials. A recent customer wants to receive high level service of all parts as Qualify, Delivery, Cost and Product. Therefore, Enterprise effort to supply for customers needs use some techniques like Data Mining, POS, MIS. Inventory and Logistics cost is the highest expense of all cost from first supplier to final customer on supply routine. So, SCM's basic purpose is reduce to that cost. So that this paper explain necessary, background, concept of SCM, analyze several using methodology and function of main SCM solution, after propose to ATP model include arithmetic procedure, functions, input data for determines available due date.
