This study used the Q-method to derive the structure of subjective opinions and perceptions of university students about the behavior of food delivery agency service provided by staff not directly employed in restaurants. For this purpose, the Q factor analysis was performed using the PC QUANL program for the Q-sort, which consists of a statement card, a P-sample, and a classification process. The results were classified into three types. The factor names were set as the first type (N = 7): efficiency seeking type, the second type (N = 19): benefit seeking type, and the third type [(N = 6): cost-effectiveness seeking type. The characteristics of each type are Type 1:Types that recognize aspects that are efficient for both consumers and restaurants, Type 2: Types of recognizing aspects of being benefited from speed, convenience and benefit, Type 3: Although it contributes to labor cost savings, it appears to recognize price and quality aspects in the initial market, which is burdened by consumers. The purpose of this study is to derive the problems of food delivery agency service business according to the three types and to provide strategic implications for the development direction and improvement plan.

This study is to investigate the effect of beauty lifestyle on the quality of life of middle-aged women. For this study, 417 middle-aged women aged 35-65 years living in Seoul, Gyeonggi, Gwangju, Sejong, and Daejeon were conducted from February 27, 2021 to March 14, 2021. As a result of this study, the correlation of quality of life of middle-aged women according to beauty lifestyle was positively correlated in the order of show-off type, appearance-seeking type, practicality-seeking type, and fashion-seeking type. In addition, it was found that the practical pursuit of beauty lifestyle and the pursuit of show-off affect the quality of life of middle-aged women. Therefore, it is necessary to develop customized communication information and marketing strategies for beauty products based on the ambivalent perspective that pursues economic efficiency and luxury for the practical and flaunting types that can have a positive impact on the quality of life of middle-aged women.

The purpose of this study is to determine factors of FDI inflows which positively influence economic development. While MNCs ultimately decide on which country to engage in FDI, it can be affected by the general investment environment of host countries. Thus, it may be closely linked to national macro socio-economic factors. In the fixed-effect panel regression analysis using 30 years of data of 13 developed countries and 15 developing countries, results indicate that labor redemption exerts the greatest influence on global FDI inflows; this implies that FDI decisions are based on locations featuring higher productivity by the reduction of labor costs. According to the level of economic development, the motive of FDI inflows differs. In developed countries, GDP, government expenditure and consumer expenditure exert the greatest influence on FDI inflows; which shows characteristics of market seeking and horizontal investment. However, in developing countries, labor redemption and human capital exert the greatest influence on FDI inflows; which shows characteristics of efficiency seeking and vertical investment.

The purpose of this study is to segment an infant's wear market on the base of housewife's fashion life-style for satisfaction of varied needs and high efficiency of marketing activity. This study was used 183 questionnaires (20∼30 generation housewife in Seoul) for statistical analysis. This study was used factor analysis and cluster analysis to group same respondents and frequency analysis, x2_analysis, ANOVA, duncan-test to analyze characteristics of demographics, clothing purchase pattern for each segmented group. The respondents were divided into 4 groups of differnt housewife's fashion life-style matte tons according to the results of analysis. The findings of the research on each groups are summarized as follows: 1) Subdividing market was classified such as a fashion-seeking/shoping-oriented group, personality-seeking group, practical/planning group, traditional conservative group. 2) According to characteristics of demographics in Subdividing market, there were significant difference in their school career, family monthly income, existence of job. 3) According to clothing purchase pattern in Subdividing market, there were significant difference in housewife's fashion life-style. But there were only partly significant difference in characteristics of demographics. In this study, housewife's fashion life-style segmentation in infant's wear market has purpose that marketing managers are given these infornations and various wants of consumers can be satisfied.

The study specifically aimed to identify factors affecting business longevity. It focused on knowing how embroidery enterprises managed to persist in the industry for many years despite the competitive business environment. After discovering the significant relationships of such factors to longevity, problems experienced by the enterprise cluster were ascertained in order to come up with recommendations that can be proposed to the enterprise owners. Embroidery entrepreneurs have been experiencing a continuous decline in sales due to lack of innovation and intense competition. In the evaluation of their personal entrepreneurial competencies, they scored low on risk-taking, persuasion and networking, and opportunity seeking; thus, implying that these are their weaknesses. On the other hand, the statistical results of this study say that longevity is a function of the entrepreneur's competencies (i.e., persistence, commitment to work contract, demand for quality and efficiency, information seeking, and systematic planning or monitoring), the generation currently managing the business, competition, and the customer's preferences. These results suggest that these independent variables are significant and are deemed critical to business longevity. Thus, entrepreneurs have to find ways on how to use these competencies as an advantage in reinventing their businesses and in reviving their industry.

This study identifies the spectrum of different forms of sharing labor in farm houses following the increase in the production of organic produce and deals with the gender division of labor and every day life of the farm households. The increased labor burdens of organic farming give more work opportunities to wives, weakening the gender barriers. However, some of the farm households seeking for economic feasibility are strengthening the gender barriers by specialized work divisions, leading to outside order labor of harvest, sorting, and packaging in order to increase efficiency in agricultural management in extreme cases. Even in the alternative distribution system, farm households has become subject to the distribution system as it is shown that coop claimed the segmentation of sorting work. This is because the convenience of the customers goes before the advantages of producers. Jinju, seeking for economic feasibility, has established the springboard for growth by greenhouse through monoculture and specialization and are operating economic growth stably. Farm couples with this condition, where their incomes are relatively high, are attempting to recharge their energy during low seasons. It is expected that this will be a model case of conventionalization of organic farming. Significance of organic farming in this matter is discussed.

We study how to determine backorder cost at the warehouse in a one-warehouse/N-retailer distribution system such that channel efficiency (minimizing total system costs) is improved. We define backorder costs as compensation that the warehouse pays to the retailer for the number or orders delayed due to stockout at the warehouse. We answer two questions : (1) "Should the warehouse compensate for his backorder\ulcorner" and (2) "Is there any equilibrium for both the warehouse and retailer while they are seeking for their own profits\ulcorner" We show that : (1) "The warehouse should pay backorder costs for the sake of channel efficiency." and (2) "There exists an equilibrium that is infiuenced by the amount of compensation." First, we prove the existence of a mutually acceptable equilibrium for both the warehouse and the retailer, which is different from Nash equilibrium because they independently maximize their respective profits with incomplete information about each other. Second, we prove that the equilibrium moves to a point such that channel efficiency is improved if the warehouse compensates the retailers for his backorders. We show the existence of an optimal compensation that minimizes total system costs. Third, we show that the amount of optimal compensation increases as the ratio of mean lead time for the warehouse to that for the retailer increases.ouse to that for the retailer increases.

Many papers have used a two-stage approach of first calculating DEA efficiency scores and then seeking to correlate these scores with various environmental variables. Most of the studies have not checked whether such a two-stage approach is statistically valid for identifying significant environmental variables. Recently Simar and Wilson (2007) (SW) introduce a sensible data generating process and bootstrap procedure based on truncated regression for the two-stage approach. Banker and Natarajan (2008) (BN) provide a statistical foundation for the two-stage approach comprising a DEA followed by an ordinary least squares or maximum likelihood estimation. Researchers have to identify an approach suitable for their research circumstances in terms of properties, merits, demerits, and robustness to plausible departures from its chosen data generating process. We summarize the foundations and properties of the two-stage procedures suggested by SW and BN. And we discuss merits and demerits of those procedures. Also using Monte Carlo simulation we assess their relative performance under several misspecified settings.
