유색콩의 재배연도 및 파종기에 따른 생육 및 수량과 이들의 유전력
박재훈,주용하,정길웅 한국국제농업개발학회 2004 韓國國際農業開發學會誌 Vol.16 No.4
노지에서 비적기재배를 위한 재배연도 및 파종기(4월 15일-조파, 5월 15일-적파, 6월 15일-만파)에 따른 유색콩(대추밤콩, 검정콩1호, 진주1호, 푸른콩)의 생육 및 수량형질의 특성과 유전력을 조사하여 특수콩 품종육성 및 재배 생리적 특성에 대한 기초 자료를 제공하고자 2001년부터 2002년까지 수행한 시험 결과는 다음과 같다. 1. 파종기에 따른 경장은 조파에서 만파로 갈수록 감소하였고, 경직경과 주경절수는 조파와 적파에 비해 만파에서 적었다. 품종에는 경장, 경직경, 주경절수 모두 푸른콩이 가장 크고 굵고 많았다. 2. 분지수와 분지절수는 조파에서 만파로 갈수록 감소하였으며, 분지수는 품종간 차이가 없었고, 분지절수는 푸른콩이 가장 많았다. 3. 100립중은 조파에서 높았으며, 품종 중에는 대추밤콩이 가장 컸고, 진주1호가 가장 작았다. 입중과 10a당 종실수량은 조파에서 만파로 갈수록 감소하였으며, 입중은 검정콩1호가 가장 무거웠고, 10a당 종실수량은 대추밤콩이 가장 많았다. 4. 생육형질의 유전력은 경장이 92%로 가장 높았으며, 수량형질은 100립중이 99%로 가장 높았다. For two years, from 2001 to 2002, this experiment was conducted to investigate growth and yield characters as influenced by different planting dates and cultivation years in order to non-optimal cultivation at field in colored soybean. Varieties used in the experiment were four varieties such as Daechubamkong, Pureunkong, Geomjeongkong 1, and Jinju 1. These varieties were planted on April 15 (early planting), May 15 (optimum planting), and June 15 (late planting), respectively. Stem height rep-resented by different planting dates as early, optimum and late planting had gradually decreased from early to late planting and stem diameter and number of stem nodes were lower in late planting than in early and optimum plantings. Stem height, stem diameter, and number of stem nodes were the tallest, the thickest, and the most Pureunkong of varieties. The number of branches and number of branch nodes had gradually decreased from early to late planting. The number of branches of all varieties was not different and the number of branch nodes was largest Pureunkong of varieties. One hundred seed weight was higher on April 15 as early planting and Daechubamkong was the highest among varieties whereas Jinju 1 was the smallest. Seed weight and seed yield per ten are had gradually decreased from early to late planting. Seed weight was the heaviest Geomjeongkong 1 of varieties and seed yield per ten are was the largest Daechubamkong of varieties. Heritability mean in growth characters tested for two years was the highest in stem height that was 92%. Heritability mean in yield characters was the highest in one hundred seed weight which was 99%.

In order to understand natural language, we have to follow the process "Input → Lexical Analysis → Syntactic Analysis → Semantic Analysis". Among those, "syntactic analysis" plays the most important role since it is able to be applied to various fields such as natural language query systems, natural language interface systems, text summary systems, and machine translation systems. It is also important to analyze a sentence containing ambiguity. In this paper, we propose an algorithm to parse the Korean language using chart. It is implemented using Prolog programming language.
Security Considerations for a Connected Car
Jae Woong Joo,Jeong Kyu Lee,Jong Hyuk Park 한국정보기술융합학회 2015 JoC Vol.6 No.2
A connected car offers various information services and entertainment services inside the car because of the addition of the network connection function as a connection between a device inside the car and an outside network. This network can connect the car with a network such as 3G/LTE to allow a bilateral real-time service. This allows the “smart devicing” of the car. However, because of the addition of the abovementioned function, the car is exposed to various safety accidents. In this paper, we analyze the security threats posed in a connected car environment and discuss the trend of research concerning safety in such an environment. In addition the application platform future is also discussed.
LISS : Log Data Integrity Support Scheme for Reliable Log Analysis of OSP
Jae Woong Joo,Jong Hyuk Park,Sang Kee Suk,Deok Gyu Lee 한국정보기술융합학회 2014 JoC Vol.5 No.4
With the development of information technology, digital works are copied illegally without the consent of copyright owners. The copied works are then spread rapidly across the world by online service providers (OSPs). Some OSPs ignore unlawful acts to create profits and commit additional criminal acts to hide their unlawful acts, such as changing or deleting log files. Consequently, there has been research on digital forensic technology to protect the intellectual copyrights of digital works and ensure integrity. In this paper, we propose a log data integrity support scheme for the reliable log analysis of OSP (LISS). The proposed scheme is used to monitor OSP events on the basis of reliable logs, thereby preventing unlawful acts such as filtering detour, and the omission, forgery, and alteration of log records; it also supports the integrity of log files essential for digital forensic investigations.

Rear collisions to expressway work trucks result many casualties these days. But, currently, no special measure are being taken except deploying sign trucks behind the working trucks. In the U.S and Europe, trucks with TMA(Truck Mounted Attenuator) are being deployed behind the working truck, which is regarded as the standard method for work area safety, thereby reducing the fatality rates and property damage tremendously. Also, standard for the performance of TMA are established and TMA can be used in the field only when it satisfies the standard. In Korea, neither the standard for nor any guide to the TMA exists. In the situation some manufacturer developed TMA without proper performance evaluation and marketed limited number of TMAs in the field. In the study, NCHRP350, which is the performance standard of expressway safety features of U.S. and materials related to the TMA standard in Europe have been reviewed to establish the Korean performance criteria. Based on the review, and incorporating existing Korean standard for crash cushions, domestic standard for TMA has been proposed and applied in developing Korean TMA and crash tested it to verify the performance. The original design developed was crash tested and modified. The newly proposed design was studied using impact simulation program several times. Modifications were made after each Simulation and prototype was built and crash tested as per the newly established TMA performance criteria.

최근 금융과 IT 가 결합한 핀테크 산업이 빠르게 성장하고 있다. 전통적 금융 서비스에서 벗어나 소비자 접근성이 높은 인터넷, 모바일 기반 디바이스의 장점을 활용하여 송금, 결제, 자산관리 등 다양한 분야의 금융서비스를 제공한다. 하지만 핀테크 기술 발전으로 네트워크, 클라이언트, 시스템 등 각각의 부문에서 새로운 보안 위협 요소가 증가 할 것이다. 본 논문에서는 핀테크 보안의 고려사항과 연구동향에 대해 살펴보고 현재 핀테크 분야에서 보안이 적용된 시스템에 대해 분석하고 취급되는 정보보호의 중요성에 대해 고찰한다.
