This study examined the relationships between the service convenience of restaurant kiosks and customer value, satisfaction, and trust. To this end, analyses were conducted with adults aged at least 18 years throughout the country who reported that they had used restaurant kiosks at least once over the last year. Information on restaurant kiosks was provided to minimize the possibility of errors in the survey. According to the results, first, the decision-making convenience and the convenience of restaurant kiosks were shown to have significant effects on the customer value. On the other hand, the place convenience and transaction convenience had no significant effect on customer value. Second, customer value was shown to have significant effects on trust and satisfaction. Third, trust was shown to have significant effects on satisfaction. If a restaurant considers kiosks in terms of customer service convenience, not labor cost reduction, they will maintain long-term relationships and enhance their differentiation by increasing satisfaction and trust. This study aims to present differentiated marketing strategies and practical implications of restaurants that have introduced kiosks.

Hand leaf thinning for improvement of fruit coloration and quality is one of the most labor-consuming works in Korean apple cultivation. The study was aimed at investigating whether foliar application of two chelate compounds (Cu-EDTA, Fe-EDTA) could defoliate effectively 'Hongro'/M.9 apple leaves and enhance fruit coloration and quality. At 30 days before harvest, foliar spray with two chelate compounds defoliated significantly the apple leaves. Chelate treatments did not affect the leaf chlorophyll content. High concentration of chelates decreased drastically photosynthetic rate of true leaves, and then it stayed in low levels, whereas low levels of chelates reduced sharply the photosynthetic rate but it was gradually restored over time. Cu-EDTA regardless of its concentration triggered higher defoliation compared to Fe-EDTA. Consequently, higher defoliation improved light interception of fruits and accumulated more anthocyanin. Particularly, Cu-EDTA could target mainly fruit cluster leaves which affect directly light interception of the fruits, i.e. more selective defoliants compared to Fe-EDTA. However, 3% Cu-EDTA rather defoliated excessively, accompanying with reduction of fruit weight and soluble solids. Therefore, our results suggest that 1% Cu-EDTA which defoliates properly the fruit cluster leaves could improve coloration and quality of 'Hongro'/M.9 apple fruits.

The ratio between the unlicensed dental technician and the licensed was 24.83% and 67.11% each . The former must be replaced by the licensed. And the latter ought to try to improve their culture and technique. 3. Overtime payment must be paid for those who work above eight hours. 4. It takes 5 days at a minimum for the production of dental prosthesis with both stability and esthetics. 5. Every Saturday afternoon, Sunday and national holiday must be free. 6. Bonus must be paid 600% a year at a minimum. The system of retirement allowance should be active. All dental technicians ought to be affliated with their labor union and medica insurance. 7. Such dental restoration as porcelain and crown and bridge prosthesis must by increased to a degree between 30% and 50% at a minimum and the reduction system of charge for a dental technique has to be abolished. 8. The general working conditions of dental laboratory, especially pay and working hour must be improved. 9. To advance the service improvement of dental treatment and the banishment of illegal one, the medical insurance of crown and bridge prosthesis must be generally practised. 10. Ill case of the staff cull:lloyulent of dental laboratory, minimem wage system must be observed. 11. Directing dentist system on the ertablisment of dental laboratory must be abelished or wholly improved.

Barley mild mosaic virus(BaMMV) is a soilborne Bymovirus vectored by root-infecting fungus, Polymyxa graminis. Mechanism of cultivar's resistance to BaMMV in field tests are difficult to assess since resistance could be either due to the virus or to P. graminis, or both. Whereas, available mechanical inoculation methods for BaMMV and other related viruses are labor intensive, give inconsistent results and generally result in low infection rates. Inoculation method using stick with gauze(SWG) was developed for BaMMV. The improved method proved to be simple, efficient, and reliable. The infected leaf tissues were preserved by drying in a frozen state under high vaccum(freeze dried barley infected leaves) to circumvent reduction of virus infectivity during storage. Five Korean barley cultivars were mechanically inoculated with BaMMV-infected sap by the improved method. Infection rates obtained were compared with natural infection. Cultivar Naehanssalbori showed resistance to BaMMV in the field trials but was found highly susceptible in the greenhouse tests by mechanical inoculation, indicating that the field resistance may be possibly due to resistance to P. graminis.

It is expected that the typical lifestyle of the future will be transformed into an opulent and comfortable existence as the quality of life improves due to the increase in household income and reduction in working hours. In the meantime, as the standard of living becomes increasingly more comfortable and plentiful, the toll on physical health becomes magnified as a result of obesity and insufficient exercise caused by super nutrition and change in labor conditions. This has instigated a deep awareness in fitness on the part of many people, forcing them to recognize the significance of daily exercise and physical activity. The Elliptical Cross Trainer(ECT), which has drawn wide attention recently, is a non-impact athletic apparatus that not only promotes exercise of the upper body parts in such sports as skiing but also the exercise of lower parts of the body on a treadmill. It is a type of cross training athletic gear that has been developed for aerobic exercise throughout the entire body. It has already formed a market as big as that of the treadmill in Europe, America, etc. Recently, its demand is growing sharply in the Korean markets as well as those in Northeast Asian countries. Despite such demand increase and expansion, since most of the expensive ECTs are exclusively supplied by suppliers in only a few advanced countries, localization of the ECT is urgently required in order to enhance competitiveness of Korean manufacturers and to expand the market. The ECT development project has been in full swing for approximately two year since 2004 in order to secure independent design, as well as engineering and manufacturing processes in efforts to develop a commercially viable ECT.

On the basis of data from the National Longitudinal Survey of Youth (NLSY), this paper investigates wage consequences of cumulative experience of job displacement. Unlike previous studies, we consider two measures of cumulative unemployment experience simultaneously: the total frequency and the cumulative duration of unemployment induced by job displacement. When frequency and cumulative duration compete in a wage equation, only cumulative duration remains significant for men, while only frequency matters for women. For men, a one-month increase in the cumulative duration of displacement-initiated unemployment leads to a fall in wages by 0.4 percent. This finding is quite robust with respect to various sample restrictions and/or estimation methods. For women, approximately a 2.5 percent wage reduction is associated with an additional event of displacement.

Environmental control operations have been considerably contributed to the reduction of labor cost in both plastic film and glass greenhouses since government supported projects were begun. However, some problems are still remaining on the optimal environmental control and excessive operation due to an inflexible software regulating ventilation gear - reducers. The unadjustable software caused the damage of ventilation system, resulting in heat stresses of crops. This study was performed to develop a ventilation software controlling the vent opening level, opening sequence, based on the wind direction, and control interval according to the difference between ambient and set- up temperatures. The software included a beeper system alarming urgent cases, while a manager was remote from the greenhouse. A compatible hardware with the software was also developed by using a low-cost diffused DSP controller.

This study tries to analyze whether the Earned Income Tax Credit (EITC), which was modified in 2011, has the effect of work incentive. In this sense, by establishing the 8th Wave of Korea Welfare Panel Study (2013) and the 9th Wave (2014), Furthermore, in order to overcome the methodological limit, the results of two-party analysis method will be compared by firstly carrying out multiple regression analysis and then performing propensity score matching analysis. The 535 households out of 6,025 were selected. The following are the results of multiple digression analysis and propensity score matching analysis. First, there was no statistically meaningful relationship with regard to the perception of the EITC. Second, there was a statistically meaningful result in the reduction of working hours with regard to whether a household received labor incentive or not. The study found that the revised EITC is not providing incentives which stimulates the will to work.
