Time series data on the size of Chonsei deposit has been estimated. At the end of 1997, that size has been estimated as 112 trillion Korean Won. If the Chonsei system can be moved toward the monthly rental system, it is highly probable to achieve the Pareto imporvement whether there are uncertainties or not. The new system named as the Chonsei system without the Chonsei deposite has been suggested, which can be readily to be introduced. Under this system, the owner can sustain opportunitities of using Chonsei deposit, renters can rent houses whithout the Chonsei deposity and financial intermediaries can secure safe sources of loans, which will increase BIS capital ratio of banks.

This paper presents a dynamic analysis of the interaction between incumbent firms and successful new entrepreneurs, that can provide R&D incentives when innovations are cumulative/sequential. It is argued that the insights of the basic model extend to varying market structures and regulatory environments.

In fact, some cases that successfully introduced CRM show that CRM is migrating from small scale which is typical when introduced to larger scale through various tests. The process also comprises all strategic planning, capital investments, management decisions, and tasks necessary to create a new product. manufacturing processes must be created so that the product can be produced in the product facility Therefore, this study tries to segment customer for the sieving the problem. And it make efficient customer management.

It is generally acknowledged that with the advent of digital technology we are faced with the revolutionary era in which everyone can enjoy the virtual reality with the simple motion of his or her fingertips. Specifically, this new trend enables domestic game industries to make a big takeoff in their size and capital accumulation. Considering this phenomenon, this project is designed to suggest an ideal space equipment or placement required to various forms of game industries.

Due to the rapid development of telecommunication industry, most telecom operators are investing to upgrade their access networks by using optical cables instead of copper cables. Building new telecom ducts for optical cable installation requires so huge capital expenses that most telecom operators need to remove unused copper cables in order to secure enough space to in-stall optical cables. In this paper, we will present a alternative method to extract copper from removed copper cables.

The exhibition would have benefited from a more sustained examination of the contemporary meanings and historic meanings behind fashion ideas and architecture as a communication vehicles, which reflect public preferences as an art or design. Both are based on structure, shape, and th ornament basic necessities. Skin+Bones pools contemporary exemplars and cultural capital - providing resources, creating the opportunity for new hybrids, and advancements for fashionistas who are much more interested in fashion. The overall aim of this research is to understand both fashion and architecture by analyzing exhibition and interpreting the meaning of objects that have been shown and studying the problems and obstacles to be overcome in presenting a significant meaning of fashion and architecture.

This paper deals with the capital budgeting problem of a firm where investments are risky and interrelated. The established models might be classified into two categories; One is the chance-constrained programming model and the other is the expected utility maximization model. The former has a rather limited objective function and does not consider the risk in direct manner. The latter, on the other hand, might lead to a wrong decision because it uses an approximate value of expected utility. This paper attempts to extend the applicability of the chance-constrained programming model by modifying its objective function into a more general form. The capital budgeting problem is formulated as a nonlinear 0-1 integer programming problem first, and is formulated into a linear 0-1 integer programming problem for finding a lower-bound solution of the original problem. The optimal solution of the original problem is then obtained by branch & bound algorithm.

Background: To explore mRNA expression and clinical significance of ERCC1, BRCA1, RRM1, TYMS and TUBB3 genes in tumor tissue of postoperative patients with non-small cell lung cancer (NSCLC). Materials and Methods: Sixty NSCLC patients undergoing radical operation in our hospital from Nov., 2011 to Jun., 2012 were selected. Plasmid standards of ERCC1, BRCA1, RRM1, TYMS and TUBB3 were established and standard curves were prepared by SYBR fluorescent real-time quantitative PCR analysis. Samples from tumor centers were taken to detect mRNA expression of ERCC1, BRCA1, RRM1, TYMS and TUBB3 genes in cancerous tissue during operation. The total mRNA expression quantities were compared according to different clinical characteristics. Results: The total expression quantities of 5 genotypes from high to low were ERCC1>RRM1>TUBB3>TYMS>BRCA1 in turn. By pairwise comparisons, other differences showed statistical significance (p<0.05 or p<0.01) except for TYMS and TUBB3 (p>0.05); the low expression rates from high to low were ERCC1>TYMS>TUBB3>TUBB3>RRM1>BRCA1 in turn. The expression quantities of BRCA1, RRM1 and TYMS in males, smokers and patients without adenocarcinoma were all significantly higher than that in females, non-smokers and patients with adenocarcinoma, and significant differences were present (p<0.05 or p<0.01). In terms of pathological staging, the expression quantities of BRCA1, RRM1 and TYMS in phases IIa~IIb and IIIa~IIIb had a tendency to be greater than in phases I and IV. Conclusions: Resistance to chemotherapy and sensitivity to targeted therapy differ among patients with NSCLC. Differences in gene expression in different individuals were also revealed. Only according to personalized detection results can individualized therapeutic regimens be worked out, which is a new direction for oncotherapy.

PURPOSES : The objective of this study is to identify the characteristics affecting traffic accidents that have occurred in 564 industrial complexes nationwide from 2011 to 2015. METHODS : The traffic accidents were specified using various factors such as industrial complex type (national VS. general), industrial complex degradation (old VS. non-old), location of complex (capital VS. non-capital), and traffic law violation (speeding, signal violation, and median invasion). The average number of crashes and accident ratio (fatal, severe, and both) in terms of characteristics of industrial complexes were calculated. With a sample of crashes of the industrial complexes for 5 years, statistical significances were tested to analyze and compare the differences based on industrial complex and traffic law characteristics using parametric and non-parametric methods. RESULTS : From statistical results, it is observed that the crash frequency occurring in old industrial complexes is three times higher than that in non-old industrial complexes. Old industrial complexes located in a capital area, old national industrial complexes, and old general industrial complexes are considerably related to higher crash frequency, but the fatal accident ratio appeared to have no statistical difference across industrial complex characteristics. Severe crashes are more likely to occur in non-old industrial complexes on an average. CONCLUSIONS : It is necessary to eliminate potential threats to roads and traffic in the same manner as illegal parking in industrial complexes through the restoration of old industrial complexes. To improve the efficiency of road infrastructure, efforts should be made to improve traffic safety in accordance with industrial characteristics such as planning and operation of relevant local government programs.

In a corporate financing, the decision of optimal capital structure is becoming more critical issues and still remaining a problem to be solved though many of researcher have studied. Particularly, shipping companies need a huge amount of capital finance for new vessel's capacity and then they are considering what is the best capital structure. In this point of view, this study tries to investigate the determinants of debit maturity structure focused on the Korean shipping industry. As results of panel regression analysis, firm size, liquidity, chance of growth, good cash flow are major determinants of debit expiration structure in the Korean shipping companies.
