A Conditional Unification Based Parsing for Korean Using Sentence-Type Information
Yang Seungweon ;
Journal of the Korea Industrial Information Systems Research, volume 9, issue 4, 2004, Pages 1~7
In this thesis, we introduce a parsing method which use information of the post position in Korean to get the exact parsing tree. In order to implement this method we classified categories of the predicates, and defined sentence-types based on these categories. We tried to make parsing using the method grasping the grammatical role of the noun phrase that have to exist in each sentence-type. In parser control mechanism, we use some heuristics based on linguistic frame. We use conditional unification to implement analysis. It is Possible to reduce ambiguous because the parsing method suggested helps to Prune the branches which are unnecessary.
A Study on the Rinsing Control Method in the Gilding Process
Kim Ki Joon ;
Journal of the Korea Industrial Information Systems Research, volume 9, issue 4, 2004, Pages 8~15
Gilding process make thin membrane with other metals to surface of metal and metalloid. It control the hydrogen ion and oxalic acid density with rinsing work since the process used to acid and alkali. Therefore, in this study, several control method applied the gilding process. It desired to the optimal controller and their results can be save on water resource by useful feed of rinsing. And there is quite a possibility of uniform production due to fixed control of acid and alkali. Also it can be contributed the competition power because of lower production unit cost. Especially, this control method to be developed can be applied to any process without mathematical model. And it can be changed their algorithm more easily, if control object is changed.

Journal of the Korea Industrial Information Systems Research, volume 9, issue 4, 2004, Pages 16~25
A Classifier System is a system based on rules to invent new rules from the present useful ones. In this paper, Genetic Algorithms are proposed to find good classification rule of Classifier System which can extract useful information from huge database. The proposed scheme is applied to the real problems such as the car insurance problem to evaluate the performance of Genetic Algorithm based classifier systems.

Hwang Byung-Kon ;
Journal of the Korea Industrial Information Systems Research, volume 9, issue 4, 2004, Pages 26~31
Due to the recent explosive progress of Web, We can easily access a large number of images from m. In this paper, we describe our approach of developing a general purpose content based image retrieval system over the H using a Web agent. The Web agent extracts text information of images from the links and file contents in HTML. The proposed system retrieves the images from database using the query by sketch and the query by example on Web browser. Experimental results demonstrate the effectiveness of the new approach.

Journal of the Korea Industrial Information Systems Research, volume 9, issue 4, 2004, Pages 32~40
This study tried to analyze the characteristic data, gathered by the semantic differential method, of respondents, user manuals and agricultural machines with the traditional statistical approach, i.e., cluster analysis and factor analysis semantic differential methods. Though the existing papers of the traditional sensory engineering only suggested the fragmentary result of analysis, this study tries to analyze the data with step-by-step approach, in which this study is analyzing the data with cluster analysis to get the characteristics of respondents, and then using the factor analysis to condensing the adjectives of describing the manual characteristics into several components. Concludingly, this study suggested a prototype of analyzing the semantic differential data with using cluster analysis and factor analysis.

Journal of the Korea Industrial Information Systems Research, volume 9, issue 4, 2004, Pages 41~46
This paper presents a new semi- systolic architecture for
operation. First of all the previous architecture proposed by Lee et al. is analysed and then we present a new algorithm and it's architecture for
operation based on AOP (all one polynomial) to solve the shortcomings in the architecture. Proposed architecture has an efficient configuration than other previous architectures. It is useful for implementing the exponentiation architecture, which is the core operation in public-key cryptosystems.

Kim Eun-Jung ; Ryu Hee-Yeol ;
Journal of the Korea Industrial Information Systems Research, volume 9, issue 4, 2004, Pages 47~55
Most questions made for remote examinations on web-based education system use methods of making questions using fixed questions or randomly using item pools or automatically using degree of difficulty. Particularly, automatically selection methods using degree of difficulty is the kernel of a question that objectivity of examination questions by degree of difficulty adjustment based result of examination. This paper is use automatically selection methods for examination on web-based education system. Therefore we present new algorithms of mediateness degree of difficulty as regards education ability of students for adjust the degree of difficulty. We identified this algorithms is more effective as compared with previously algorithms on web-based education system
Study of Rate of Human Error by Workers in the Field based on Occupation
Im Wan-Hee ;
Journal of the Korea Industrial Information Systems Research, volume 9, issue 4, 2004, Pages 56~67
This study analyzes human error of workers performing simple repetitive tasks, and in order to prepare preventative measures, 486 people were used as subjects. The results of the study are like the following. First, the biggest cause of human error showed to be the worker himself in
of the cases, machinery showed to be the cause in
of the cases and management showed to be the cause in
of the cases. The results show that most of the human error occurred due to the worker performing simple repetitive tasks and the human errors showed to be caused more by bad ergonomics and long hours rather than by problems with machinery. In addition, the area with the highest rate of human error showed to be the Human Information Processing System with Task Input Error being the highest with
, followed by Judgement and Memory Error with
and Recognition Verification Error with
. Although fully automated tasks may reduce the rate of human error we must focus on lowering the rate of problems arising from spontaneous errors caused by workers performing simple repetitive tasks by continuously renewing plans and budgets in order to standardize tasks by incorporating cyclic positioning according to experience and positional exchange and by inspecting the workplace to increase efficiency of the workers.

On the Study of Key Management in Mobile Ad Hoc Networks
Kim Si-Gwan ; Shin Yoon-Shik ; Lim Eun-Ki ;
Journal of the Korea Industrial Information Systems Research, volume 9, issue 4, 2004, Pages 90~98
This paper covers the issue of securing ad hoc networks. Such networks exhibit a number of characteristics that make such a task challenging. One of the major challenges is that ad hoc networks typically lack a fixed infrastructure both in form of physical infrastructure such as routers, servers, and stable communication links and in the form of an organizational or administrative infrastructure. Another difficulty lies in the highly dynamic nature of ad hoc networks since new nodes can join and leave the network at any time. The major problem in providing security services in such infrastructure less networks is how to manage the cryptographic keys that are needed. In order to design practical and efficient key management systems it is necessary to understand the characteristics of ad hoc networks and why traditional key management systems cannot be used. These issues are covered and we also present a new efficient key management solutions. Finally we show that the proposed method is more efficient than the previous works through simulations.
