Over the course of the recent global financial crisis, emerging economies experienced massive swings in capital inflows. In this paper, we estimate a VAR model to assess the impact of capital inflow shocks, which are identified using a set of sign restrictions, on house prices in Korea. We base the analysis on three alternative measures of capital inflows: net total inflows, net portfolio inflows and gross total inflows. The results suggest that capital inflow shocks have a significantly positive and persistent effect on real house prices. Although shocks to capital inflows are found to be substantially more important for Korean asset markets than for other OECD countries, their overall explanatory power is modest. Using regional house price data we also show that capital inflow shocks have an asymmetric effect on property markets across the seven largest Korean cities and across different parts of Seoul.

This paper is a study on the model that measures economic values for the non-market properties of e-Business. For development of this model, first of all, we reviewed the properties of e-Business service, and looked around the relation between customer satisfaction and/or payment value and e-Business properties. In addition, we checked the method to measure economic values of these properties. This measurement method is the contingent valuation method which is a method of measuring the value of the environmental product. We modified it to adapt to the e-Business. Finally, in this paper, we proposed an economic value model which measures the value of willingness to pay(WTP) to our objectives. However, there could be some restrictions at the time when surveying empirically. Therefore, the succeeding study should be done in order to improve these restrictions some day.

In general, recognition of Hand written characters requires to apply an algorithm which takes into consideration of the individual differences. Considering the differences, the authors propose a new method for recognizing Hand written Hangul by parallel procedure analyzing both the segments and the structure of the character. In the previous recognition method proposed by the authors two severe restrictions were placed. The element representing consonant/O/ was closed, and the character elements were separated each other. In order to remove these two restrictions, the authors propose an improved algorithm. It is shown that Hangul in its simplified form is well recognized by using this improved algorithm.

We consider the state price densities that are implicit in financial asset prices. In the pricing of an option, the state price density is proportional to the second derivative of the option pricing function and this relationship together with no arbitrage principle imposes restrictions on the pricing function such as monotonicity and convexity. Since the state price density is a proper density function and most of the shape constraints are caused by this, we propose to estimate the state price density directly by specifying candidate densities in a flexible nonparametric way and applying methods of regularization under extra constraints. The problem is easy to solve and the resulting state price density estimates satisfy all the restrictions required by economic theory.

Construction companies economic to lighten the restrictions on safety education and training due to the domestic recession as long as the global downturn. With this, the Korean government lightened that restrictions, but the incidents are being sharply increased nowadays. The construction industry is more hazardous than any others, so, they insist to reinforce the training for incidents prevention, but it is prone to be disregarded at the subcontractors of the bigger construction companies due to their financial problems. According to these matters, this study hereby surveyed regarding their suggestions for the improvements of the training concepts through questionnaires below.

The targeted nuclease clustered, regularly interspaced short palindromic repeats/CRISPR-associated proteins (CRISPR/Cas) system has recently emerged as a prominent gene manipulation method. Because of its ease in programming targeted DNA/protein binding through RNA in a vast range of organisms, this prokaryotic defense system is a versatile tool with many applications in the research field as well as high potential in agricultural and clinical improvements. This review will present a brief history that led to its discovery and adaptation. We also present some of its restrictions, and modifications that have been performed to overcome such restrictions, focusing specifically on the most common CRISPR/Cas9 mediated non-homologous end joint repair.

This study examined return policies of the Korean retailers and their differences by retail format. Return policies of 363 retailers including dept stores, discount stores, brand consignment stores, small shops, outlet stores, TV home shopping companies, and internet shopping malls were collected. Acceptance of refund or/and exchange, return grace period, and return requirements or restrictions of each retailer were analyzed. The results showed that most retail formats except small shops and internet shopping malls allowed refund. The seven day return grace period was most common though large retail chains allowed more generous time frames and small shops allowed shorter dates. Restrictions for return varied by retailers and retail formats. Generally retailers followed the guidelines of consumer protection laws. The study discussed implications of return policy analysis.

The efficient send and receive of information in VANET improves the efficiency of the safety and traffic services advertisment and discovery. However, if the V2V is the only communication system used, the restrictions of the urban environment and network drop the performance of VANET. In order to improve the performance of the network, it is necessary to use V2I communication as well as V2V communication. Therefore, RSUs must be placed in the environment. However due to the high costs of placement, the full coverage of the environment would not be possible. Therefore, it is necessary to optimally install a limited number of RSUs in the environment.

This paper reanalyzes examples with missing verbs. Northern Mandarin rejects argument nominal phrases after a silent verb, as well as silent verbs inside islands. These restrictions suggest a grammatical process which silences verbs. I propose that these restrictions are the result of VP-topicalization followed by ellipsis. This analysis accounts for the island sensitivity of these constructions: since VP-topicalization feeds ellipsis, constructions with elided VPs are not derivable from configurations where movement is impossible. Also, to avoid topicalization along with the VP, the argument must move out of VP; the subsequent topicalization of the VP containing the argument's trace would then give rise to a configuration where that trace c-commands the moved-out DP. Adjuncts do not pose a problem because they are located outside of that smallest VP-shell. The data presented here are accommodated by neither of Tang's (2001) proposals for silent verbs (gapping and empty verbs). Instead, they provide support for a third source for silent verbs, VP-ellipsis via topicalization.

There are a fair number of suffixes in English whose conditions on attachment refer to stress and/or segmental information contained within the words they attach to (see Siegel 1974, Jespersen 1942 and Marchand 1969). Through a wide study of relevant data, we will delve deeply into such phonological restrictions on the bases, which may as well be divided into four distinct types: haplological constraints; segmental constraints; prosodic constraints; and mixed types. We will further assume here that the category/ subcategorization requirements of affixes are subject to the Projection Principle (PP) as conceived in Kiparsky (1983). It will be shown how this PP interacts with phonological constraints placed upon the affix in question, especially in the treatment of-ful (inventful/mournful) or -en (longen/lengthen). Our account of problematic affixations in English is based on a number of violable constraints in OT.
