This study is designed to review the methods of duplicate copies decision making in the academic library. In this thesis, I surveyed queueing & markov model, statistical model, and simulation model. The contents of the study can be summarized as follows: 1) Queueing and markov model is used for one of duplicate copies decision-making methods. This model was suggested by Leimkuler, Morse, and Chen, etc. Leimkuler proposed growth model, storage model, and availability model through using system analysis method. Queueing theory is a n.0, pplied to Leimkuler's availability model. Morse ad Chen a n.0, pplied queueing and markov model to their theory. They used queueing theory for measuring satisfaction level and Markov model for predicting user demand. 2) Another model of duplicate copies decision-making methods is statistical model. This model is suggested by Grant and Sohn, Jung Pyo. Grant suggested a model with a formula to satisfy the user demand more than 95%, Sohn, Jung Pyo suggested a model with two formulars: one for duplicate copies decision-making by using standard deviation and the other for duplicate copies predicting by using coefficient of variation. 3) Simulation model is used for one of duplicate copies decision-making methods. This model is suggested by Buckland and Arms. Buckland considered both loan period and duplicate copies simultaneously in his simulation model. Arms suggested computer-simulation model as one of duplicate copies decision-making methods. These methods can help improve the efficiency of collection development and solve some problems (space, staff, budget, etc, ) of Korean academic libraries today.

It is a basic rule in the credit law that original documents are required unless otherwise stipulated by the credit. Due to modern technology enabling documents to be produced in many ways it may not always to decide whether a document is original or a photocopy. In consideration of modern technology and the advent of new methods of document production, ICC has drawn up the provisions on original documents in Article 22 (b) of UCP 400 for the first time. The equivalent provision in UCP 500 is Article 20 (b). As a result of many queries to ICC Banking Commission on what constitutes an "original" documents under UCP 500 and several court cases in connection with original documents, the ICC Banking Commission has issued Decision on original documents in July 1999. Based on this Decision, the ICC dealt it in Article 17 under UCP 600 which came into force on July 1, 2007. There are some changes, replacements and new provisions of UCP 600 concerning original documents and copies. Importers, exporters, insurance companies, other third parties and, above all, banks should pay attention to some changes and implications of UCP 600 concerning original documents and copies. The purpose of this paper is to examine the provisions on original documents and copies under UCP 600. For this purpose, firstly this study deals with the relative provisions on original documents and copies under pre-UCP 600. Secondly this study considers the provisions on original documents and copies under UCP 600. Thirdly this study compares the provisions under pre-UCP 600 with the provisions under UCP 600. Finally this study analyzes the cases decided both home and abroad in connection with original documents. This paper contribute to help the parties to letters of credit to understand the provisions on original documents and copies under UCP 600.

The study analyzed behaviors of users in cafeterias and spatial environmental images as well to understand what factors would affect the users' satisfaction in the cafeterias. The study also looked into how interior space factors would influence the users, what the users actually want from the cafeterias when they use them and lastly, what kinds of behaviors the users would do while in the cafeteria. Through those researches, the study proposed solutions to improve the users' satisfaction in cafeterias. As a field survey research, the study observed actual conditions of cafeterias at a university as conducting spatial environmental analysis to present ways to improve students' satisfaction in cafeterias at their university. In order to achieve the research goal, the study carried out a literature analysis and a survey and visited the cafeterias to understand both actual conditions and environments of cafeterias at a university. The study also had in-depth interviews with the students. The subject of the study was those college students who have been using four cafeterias at three campuses of D university. Data was collected via surveys, observations and interviews. With the students as the research subject, the study investigated and analyzed current status of the students' using of the cafeterias, actual utilization, spatial factors and satisfaction factors. The study was mainly developed with a survey conducted and by distributing basically 200 copies of the survey each to the campuses, the study gave out 200 copies each to Suseong Campus in Daegu and Oseong Campus in Gyeongsan but 400 copies at a time to Samsung Campus in Gyeongsan because it was the main campus and had two cafeterias. To sum up, each department was instructed to answer 20~40 copies of the survey in the end. Out of 800 copies in total, 188 copies from Oseong Campus, 153 copies from Suseong Campus and 386 copies from Samsung Campus which would add up to 727 were observed to be faithful enough to be used as statistics for the study.

Although consumer ethical behavior related with illegal copies of digital software has been considered to be an important issue, not many studies have attempted to examine the issue. Firstly, this study attemped to explain the moral judgment and intention to make illegal copies of smart phone applications for college students. Secondly, psychological factors such as moral intensity and perceived risk related to making illegal copies were tested to be significantly different in individual characteristics such as experience of ethical education and past experience of making illegal copies of software, sex, age and household income. Thirdly, the effect of related factors such as psychological factors and individual characteristics was estimated to significantly influence moral judgment and intention to make illegal copies. Two step method(using LIMDEP program) was applied to estimate the model as a structural equation model. According to the results of this study, magnitude of consequences, financial risk and performance risk were found to be significantly different in income groups(less than middle class vs more than middle class). Prosecution risk was found to be significantly different in gender groups(female vs male). In addition, social consensus, financial risk, performance risk and prosecution risk were found to be significantly different in ethical education groups(experience vs no experience). Furthermore, moral judgment for making illegal copies of smart phone applications was found to be significantly influenced by income, ethical education, magnitude of consequences, temporal immediacy and social consensus. And intention to make illegal copies of smart phone applications was found to be significantly influenced by moral judgment, age, financial risk, performance risk and prosecution risk.

The principle of materialized world is the same as of human life. The human life is governed by the human mind composed of the copies of the materialized world. The stress is due to the human mind inside. The creativity is prevented by the copies in the human mind. The convergence is not easy due to the individual copy world which is different from each other. By subtraction of the copies inside the human, the creativity and convergence can be fulfilled. Syllabus of the lecture at KAIST is introduced. Students taking the lecture express the non-materialized world of human mind clearly after the subtraction the copies inside. The students who recognize the stress inside specifically can be free from the stress by discarding the copies inside.

Increasing the gene copy number has been commonly used to enhance the protein expression level in the yeast Pichia pastoris. However, this method has been shown to be effective up to a certain gene copy number, and a further increase of gene dosage can result in a decrease of expression level. Evidences indicate the gene dosage effect is product-dependent, which needs to be determined when expressing a new protein. Here, we describe a direct detection of the gene dosage effect on protein secretion through expressing the enhanced green fluorescent protein (EGFP) gene under the direction of the ${\alpha}$-factor preprosequence in a panel of yeast clones carrying increasing copies of the EGFP gene (from one to six copies). Directly examined under fluorescence microscopy, we found relatively lower levels of EGFP were secreted into the culture medium at one copy and two copies, substantial improvement of secretion appeared at three copies, plateau happened at four and five copies, and an apparent decrease of secretion happened at six copies. The secretion of EGFP being limiting at four and five copies was due to abundant intracellular accumulation of proteins, observed from the fluorescence image of yeast and confirmed by western blotting, which significantly activated the unfolded protein response indicated by the up-regulation of the BiP (the KAR2 gene product) and the protein disulfide isomerase. This study implies that tagging a reporter like GFP to a specific protein would facilitate a direct and rapid determination of the optimal gene copy number for high-yield expression.

As more generic drugs become available, the quality, safety, and efficacy of generic drugs have become a public concern. Specifically, drug interchangeability among generic copies of the same brand-name drug is a safety concern. This research proposes a Bayesian method for assessing bioequivalence between two generic copies of the same brand-name drug from two independent $2{\times}2$ crossover design experiments. Uninformative priors are considered for general use and the posterior distribution of the difference of two generic drug effects is derived from which the highest probability density interval can be evaluated. Examples are presented for illustration.
