Korean adults' internet addiction diagnosis measure, K-scale developed by Korea National Information Society Agency (NIA), has composed of 4 categories including 20 items. This scale can diagnose user's internet addiction with individual's questionnaire items. Most of previous research works were tried to know reasons of internet addiction and to judge whether adolescents are addicted or not with their samples. In this research, it is the goal to find the key component to judge individual's internet addiction by using a decision tree in the data mining field and a principal component analysis in statistics. From the experimental results, we would discover that tolerance and preoccupation factor is the most important one to affect adult's internet addiction.

Nowadays fires must be detected rapidly Abstract, and by connecting the detector's distribution, sender, transponder, receiver and others can be connected. Mechanical systems are implemented in today's buildings. However, this kind of constructing method has some disadvantages, that is, if fire happens somewhere, we cannot judge where the fires happen, and it is also difficult to judge what extent the fires reach. In order to overcome the disadvantages, in this paper, according to the tendency of combining the Ubiquitous and Intelligent Network, we propose a type of system by using the method of comparing the differences of the existed systems. The proposed system is designed to perceive the fires rapidly and confirm the fire place and fire scale correctly.

In order to analyze the nonlinear phenomena of the bifurcation and chaos caused by the switching of nonlinear switching devices in inductively coupled power transfer (ICPT) systems, a Jacobian matrix model, based on discrete mapping numerical modeling, is established to judge the system stability of the periodic closed orbit and to study the nonlinear behavior of Hopf bifurcation in a system under full resonance. The general flow of the parameter design, based on the stability principle for ICPT systems, is proposed to avoid the chaos and bifurcation phenomena caused by unreasonable parameter selection. Firstly, based on the state equation of SS-type compensation, a three-dimensional bifurcation diagram with the coupling coefficient as the bifurcation parameter is established with a numerical simulation to observe the nonlinear phenomena in the system. Then Filippov's method based on a Jacobian matrix model is adopted to deduce the boundary of stable operation and to judge the type of the bifurcation in the system. Then the general flow of the parameter design based on the stability principle for ICPT systems is proposed through the above analysis to realize stable operation under the conditions of weak coupling. Finally, an experimental platform is built to confirm the correctness of the numerical simulation and modeling.

It is the juristocracy in architecture to judge the architectural plagiarism by copyright law. The architectural plagiarism should judge by architectural criticism. From the point of the criticism to discuss architectural plagiarism, the study on artistic imitation should be preceding. The current discussion on architectural plagiarism doesn't consider artistic imitation. Therefore, the result of the discussion only focused on whether the building is plagiarizing or not. From the point of architectural criticism, there should be three considerations, which are creation, imitation, and plagiarism. In the study of Aesthetics, it theorized artistic imitation as the appropriation. With the understanding of the appropriation, contemporary art is developing the discourse on plagiarism beyond the boundary of plagiarism fundamentalism. The purpose of this study is to apply the appropriation to the discussion of architectural plagiarism. The study introduces the discourse on architectural plagiarism rather than judging it with copyright law. There so the study categorized the aesthetics standard of appropriation art, then apply it to the architecture cases. The architecture cases subjects of analysis are the glasshouse by Philip Johnson, National Museum of Australia by Howard Raggatt, and the Meiquan 22nd Century in China. At the point of the appropriation theory, the glasshouse is the only architectural appropriation, and others need to apply the evaluation criteria of plagiarism.

Rose and chrysanthemum are the most popular flowers in Korean floriculture. Sorting flowers is a labor intensive operation in cultivation of the cut flowers and needed to be mechanized. Machine vision is one of the promising solutions for this purpose. This study was carried out to develop hardware and software of a cut flower sorting system using machine vision and to test its performance. Results of this study were summarized as following; 1. Length of the cut flower measured by the machine vision system showed a good correlation with actual length of the flower at a level of the coefficients of determination (R$^2$) of 0.9948 and 0.9993 for rose and chrysanthemum respectively and average measurement errors of the system were about 2% and 1% of the shortest length of the sample flowers. The experimental result showed that the machine vision system could be used successfully to measure length of the cut flowers. 2. Stem diameter of the cut flowers measured by the machine vision system showed a correlation with actual diameter at the coefficients of determination (R$^2$) of 0.8429 and 0.9380 for rose and chrysanthemum respectively and average measurement errors of the system were about 15% and 7.5% of the shortest diameter of the sample flowers which could be a serious source of error in grading operation. It was recommended that the error rate should be considered to set up grading conditions of each class of the cut flowers. 3. Bud maturity of 20 flowers each judged using the machine vision system showed a coincidence with the judgement by inspectors at ranges of 80%∼85% and 85%∼90% for rose and chrysanthemum respectively. Performance of the machine vision system to judge bud maturity could be improved through setting up more precise criteria to judge the maturity with more samples of the flowers. 4. Quality of flower judged by stem curvature using the machine vision system showed a coincidence with the judgement by inspectors at 90% for good and 85% for bad flowers of both rose and chrysanthemum. The levels of coincidence was considered as that the machine vision system used was an acceptable system to judge the quality of flower by stem curvature.

This thesis is concerned with the study of the court attire the typical attire of the ju-dicial world in a point of time that more than 100 years have passed since the introduction of the modern judical system. In recognition of the fact that compiled data of the official uni-form or attire in Korea are insufficient this study placed its signification on the provision of information with focus on attire. As a result of studying court attire in Korea the conclusion was made as follows: Firstly Official attires in Yi Dynasty were divided by wearing embroidered insignia on the breast and the back of an official robe ac-cordint to court rank as well as by wearing Sa-mo in wadded clothes of Dan-ryeong and attaching all sorts of appurtenances including bands and shoes The Minister of Justice was equipped with Ho-pyo Dae-sa-heon equipped with Hae-chi the mayor of Seoul equipped with Un-an In the era of the Kng Young-jo the minister of Justice had no change in its of-ficial robe but the mayer(Pan-yun) of Seoul (Han-sung-bu) had Un-an(wild geese in clouds) changed into Un-hak In the King Ko-jog era the minister of Justice had Ho-pyo changed into Ssang-ho and the mayor of Seoul had Un-hak changed into Ssng-hak on embroideved insignia on the breast and back of an official robe. Laws and regulations concerning court attire began with the In-judgement Full-dress Uni-form Requlation for official-level Clerical Staff below the ordinary staff the Issue No. 14 of the Royal Ordinance in 1906 provided as $\ulcorner$the matter cincerning the Dress Regulation of the Tribunal staff of the Cho-sun Government-General$\lrcorner$the Issue No. 222 of the Royal Ordi-nance in 1911 and changed into$\ulcorner$the Regu-lation on the Dress of Judge Prosecutor At-torney and Law Count Clerk$\lrcorner$the Issue No. 12 of the Supreme Court Rule in 1953 affter the establishment of Korean Government since emancipation from the Japanese rule and into $\ulcorner$the Regulation concerning the Court Attire of Judge and law Court Clerical Staff$\lrcorner$the Issue No. 516 of the Supreme Court Rule in 1966. The judicial system in Korea is the system introduced from the foreign country rather than autogenously developed. And it came to pass through the Japanese colonial period it the beginning that it took root in Korea n was not stabilized in harmony with our native tradition. Accordingly the attare regulation in the judicial system took root in our society by accepting the Japanese attire regulation as it was and judical officials have come to wear the count attire similar to that of the Japanese imperialist era due to its influence though Korean independent goverment was established together with liberation form the Japanese rule. The more regrettable thing is that the current court attire has maintained the form greatly influenced by the U. S. court attire. Fortunately as the judicial circles have recently raised their voices for change in the court attire it has been told that the forma-tion of a meeting for a new court attire has been under way. The birth of the court attire into Which our tradition is sublimated is expected. This study end up with thinking that the must Korean thing is the most global thing in this era that people in the world are clamoring for globalization.

Shielding theory is to allow the construction of a structure that would be shielded by existing permanent structures even thought such structure extends above the height limits prescribed for such zones. This theory is mentioned as recommended practices in ICAO Annex, and is adopted, with modification, in the current Military Airbase Law, amended in August 26th 2002. However, the Military Airbase Law adopts shielding standard allowing 45 meters uniformly, which is a unique standard compared to other countries shielding guideline. The basic principle in applying the shielding theory is, after considering the circumstances of location of shielded structure, whether such structure has physical effect on aeronautical operations. Based upon the basic principle of shielding theory, the uniform application of shielding standard in the Military Airbase Law would undermine the safety of aeronautical operations. This article is to review subsection 2 of section 8 of the Military Airbase Law, which adopts modified shielding theory, and is to suggest better guideline. From a comparative analysis perspective, shielding guidelines of ICAO and other countries will be discussed. Based upon this discussion, the general problems of shielding theory and the specific problems in the Military Airbase Law will be examined. Finally, this article suggests the case-by-case application of shielding theory, considering circumstances of location, for the purpose of ensuring aviation safety.

The purpose of this study was to analyze judicial precedents related on landscape construction defects(JPLCD) and suggested the improvement plan for dealing with it. The results are as the following: 1. Landscape construction defects litigations have been increased so far since 2000 and the duration of original trial was approximately 603 days, while appeal trials took up to 550 days. Therefore, the analysis revealed that settlement of disputes were lengthy and wasteful to consumers and constructors. 2. Judgement's cost accepted by the judge was only 53.6% of appraisal's cost appraised by appraiser, therefore it revealed appraiser overestimated the repair cost of landscape construction defects. 3. According to work classification categorized by Landscape Construction Standard Specification(2008) of the Korean Institute of Landscape Architecture, landscape planting amounted to 75% of JPLCD and plaintiff(consumers)'s prevailing rate of it reached 77% to be a serious burden to constructors. 4. According to JPLCD categorized by the type of dispute, defects caused by consumer's negligence for maintenance amounted to 29% and defendant(constructors)'s prevailing rate of it reached 64% to be the main responsibility of consumers. Further study will be required to make the judge standard of landscape construction defects through legal and technical research.

To manage a phase of coding and unit-test, project managers have used to pay attention to a number of completed programs. And the manager makes a graph of progress. Usually, this graph of progress has S shape and doesn't linearly depend on the workload. So the degree of progress seems to be behind. In actual, many projects tend to be behind the schedule. Because of this reason, it is difficult to judge whether the project is behind or not in the early stage. In this paper, We propose the 'four-division model' to solve this difficulty.
