This study aimed to assess the economic value of the UX design and applied contingent valuation method (CVM) to the three smartphone screen unlock interface types: touch, fingerprint, and iris recognition. The contingent valuation method was chosen from various economic valuation approaches because the interface components such as the screen unlock are important user experience values but non-market goods which are not traded independently. Using the double-bounded dichotomous choice approach of the contingent valuation method, the survey results of the logit model showed that the economic value of touch unlock interface was 529 won, fingerprint was 4,214 won, and iris recognition was 1,316 won. That is, the fingerprint interface had the highest economic value, followed by iris recognition and touch interface. The main contribution of this research is that we examined a method for economic valuation of the UX design and generated systematic and credible results.

In the 2000s, China has been pushing the issue of San-Nong as a national priority. Farmland transfer, one of the solutions to the problem of San-Nong, has grown rapidly over the past decade. Especially, as farmland transfer was promoted, the rural economy developed and the living standards of the farmers improved greatly. However, the rigidity of farmland transfer type, which focuses on Zhuan-Bao method, hinders farmers' willingness to relocate to farmland transfer and ultimately acts as an obstacle in promoting massive farmland transfer. The purpose of this paper is to analyze the determinants of farmland transfer types and farmland transfer prices in Chinese farmers. Based on the results of the analysis, the following implications are suggested. First, farmers should be instructed to farmland transfer in a Ru-Gu manner; Second, the contract period must be long; Third, it is necessary to prepare countermeasures for the farmland transfer by crops; Fourth, Educational programs should be built for the farmers of farmland transfer.

In Korea, as the aging phenomenon accelerates, the problem of traffic accidents related to the elderly is continuously emerging. Efforts to improve this are being implemented, but unfortunately the results of these effects are not clear. Therefore, in this study, the effect of traffic characteristics and incentive policies on the return of driver's licenses of elderly drivers was reviewed. As a result of the analysis, it was confirmed that the intention to return the driver's license was low in the case of men, older people, those with low dependence on public transportation, those who undertook long driving hours, and those who took frequent trips. On the other hand, financial incentives were found to play a positive role with regard to the intention to return the driver's license. However, the effect is expected to be insignificant for those with a low intention to return the driver's license. As a result, under the current policy, it is predicted that there is a limit to improving the social problems caused by elderly drivers, meaning that it is necessary to review approaches that induce the return of their driver's licenses.

The government recently implemented policies to improve transportation for the disabled passengers. On the other hand, metropolitan public transport still lacks adequate services for these individuals. Many new cities lack urban rail lines and focus on high-floor buses for expansion. Wheelchair users can only access to double-decker low-floor seat express buses for intercity travel. This study examined the necessity and rationale for introducing low-floor seat buses by estimating the user's willingness to pay through a contingent valuation method. Two methods for eliciting the willingness to pay were adopted: open-ended and dichotomous choice questions. The binomial logit model was used to estimate the willingness to pay. The results indicated that the general public is willing to pay an additional 126.7 Korean won, while the disabled passengers are willing to pay an additional 117.5 Korean won. When translated into annual economic benefits, this amounts to approximately 35 billion Korean won.

Third-generation (3G) devicesare next-generation devices that allow the use of intelligent services and applications through the Internet of Things (IoT). As the market forexisting smart devices like smartphones and tablet PCs enters the stage of stagnation, the world is now focusing on 3G devices, parts, and services. This study is intended to measure the user's benefits from the various attributes of 3G devices by applying an economic valuation method. For this purpose, the conjoint analysis method was applied, which is one of the representative valuation methods. To apply conjoint analysis, the following attributes of 3G devicesare considered: mode of use, power efficiency, life care, and price. By applying the mixed logit model, the marginal willingness-to-pay(WTP) for each attribute was derived. The results are statistically significant. Respondents showed a high preference or complete flexibility in the mode of use attribute. And they were also found to have WTP for improvements in the life care attribute. The implications and quantitative results of this study are expected to be useful for policies and strategies in the 3G device market.

The main purpose of this study is to analyze the diversion rate by the levels of delay and the types of display. For this study, we developed the logit model by analyzing the result of SP survey of drivers who have driver's licence after manipulating a virtual driving simulator. The result of analysis was that the types of display was not statistically significant to the diversion rate. On the other hand, the levels of delay was very meaningful factor with the diversion rate. When the main road was flowing smoothly, drivers started to detour at the levels of delay 125% under the traffic free flow state. Similarly, when the levels of delay got worse, the diversion rate kept the same percentage as it was at the levels of delay 125% state which represented a smooth road condition. Likewise, when the main road's traffic flow was slow, drivers appeared to make detours at the same state of the levels of delay 125%. It was found that as the levels of delay got worse, the diversion rose higher than the diversion rate at the condition of slow traffic flow situation with the levels of delay 125%. The result of this study suggests the criterion of drivers detour point. For the conclusion, the result of study would be a reasonable reference for establishing transportation strategies by reflecting drivers' detouring property and would improve the efficiency of traffic flow.

Among several policies for industrial decentralization introduced since the 1960s, business relocation grant policies put a heavy financial burden on central and local governments. This study investigates the change in the likelihood of manufacturing establishments' relocation to the non-SMA associate with the change in business relocation grant policies. Using the mining and manufacturing survey data from 1996 to 2014, manufacturing firms' relocation decision model in nested logit structure was estimated. The data showed that the proportion of movements from the SMA to the non-SMA significantly increased after the introduction of the grant policies. However, estimation results of firms' relocation decision model indicated that the likelihood of firms relocating from the SMA to the non-SMA decreased after the introduction of the grant policies. In particular, firms' likelihood to move into the rural regions is even lower in the period of the grant extension. This suggests that increasing rate of relocations toward the rural regions may have been driven by the growing advantage of rural locations, such as low land rent and improvement in market accessibility, rather than the grants per se. This implies that the alleviation of physical and environmental constraints of the rural regions and the creation of business friendly environment such as easy access to premises at reasonable prices and strengthened linkage with the SMA, rather than simple provision of business relocation grants, needed to attract businesses in the rural regions.

This study analyzed the normalization cases of the mutual savings bank insolvency PF (MSBIPF) to suggest the appropriate improvements according to the purpose. The results were as follows. First, the original intention to normalize the MSBIPF was unsuccessful. This may be caused by the daunting situation of the real estate market along with the complex and shared interests. On the other hand, it can be responsible for the lack of evidence and related regulations as well as the lukewarm attitude on public projects. Active institutional settings are warranted to compensate the remaining insolvent businesses to PF even today and in the future. The data related to the recognized sites as the poorest 32 PF sites was compared primarily to normalize by KAMCO and the relevant sites. The area variable was the only significant variable according to the correlation analysis and logit analysis. The direct investment, diverse PF-backed bonds and the activation of the Ritz can be suggested as alternative ways of normalization with respect to the issue of the KAMCO.

This article investigates the relationships between motivation and revisit intention of visitors to Gangneung Danoje Festival as cultural festival with social demand. Out of 550 questionnaires distributed, a total of 514 usable questionnaires were collected. The hypothesized causal model was tested by logit model, which included satisfaction model to each program as well as overall satisfaction model to cultural festival. Model 1 is constructed with satisfaction and revisit intention to each program, and Model 2 with overall satisfaction and revisit intention to cultural festival. In this models causal variables were inputted including satisfaction to festival programs, frequency of visitation, days of stay, time required to destination. In Model 1 positive sign were shown by causal variables as satisfaction to each program, frequency of visitation, days of stay but negative signs was shown by time required to festival place. In Model 2 sign directions of causal variables were same in Model 1. In comparison, Model 2 is more significant than Model 1 on the basis of statistical theory as significance level and coefficient of determination. Consequently, cultural festival managers should test the satisfaction level of visitors to each program of cultural festival and make efforts to establish advanced program in order to attract more visitors.

More than one-third of the world's population still has no access to clean cooking facilities despite global interest and efforts to expand the accessibility of clean cooking fuels. They use traditional biomass, i.e., crops, animal dung and firewood, as their cooking fuel, and the health and economic damage from it is severe. As many studies have been conducted to understand the choice and transition of cooking fuel in developing countries, characteristics of household head have been addressed as one of the main fuel determinants. However, decision-making in households is not only made by household head and can vary depending on the relative characteristics of household members. Thus, this study analyses the determinants of cooking fuel choice through the samples of Cambodian couples(household head and his/her spouse) considering both characteristics of husbands and wives. As a result, it is confirmed that the effects of characteristics, such as employment, education levels, and frequency of media use, between husbands and wives on cooking fuel choice were different. This study is expected to contribute to the development of more sophisticated policies to increase clean fuel in Cambodia, given that it takes into account the characteristics of spouses who have not previously been dealt with in analyzing the determinants of cooking fuel choice and that it is difficult to find research on Cambodia.
