The purpose of this study is to examine the demographic, economic, and psychological factors that influence the quality of life (QoL) of the elderly. The data in the 'Survey on the Elderly in 2011', were collected from The Ministry of Health & Welfare and the Korea Institute for Health and Social Affairs. The samples included 3,312 out of the total of 15,146 elderly people aged from 65 to 70 years. Multiple regression analysis and path analysis were used to analyze the research model. The findings are as follows. First, the most critical factor that affected the QoL of the elderly was "subjective standard of living" with other factors including "subjective physical condition level", "depression", "total annual income", "the number of chronic disease", "self-esteem", "economic supports from their adult children", "education level", "living with their adult children or not", "sex", and "home ownership", in that order. Second, based on the path analysis results, the QoL of the elderly was influenced by "subjective physical condition level", "subjective standard of living", "depression", "self-esteem", "total annual income", "education level", and "the number of chronic disease", in that order. In particular, "depression" had a negative direct effect and an indirect effect on the QoL of the elderly, whereas "self-esteem" had a positive direct effect and indirect effect on their QoL. Third, "labor force participation status" did not affect the QoL of the elderly. However, it implied the mediating effect of "self-esteem" and "depression" on their QoL. These results show that demographic, economic, and psychological factors heavily influence the QoL of the elderly. Specifically, "depression" and "self-esteem" turn out to be mediating variables that strongly influence the QoL of the elderly. Also, "labor force participation status" does not have a positive direct effect on the QoL of the elderly but has a positive mediating effect of "depression" and "self-esteem" on their QoL.

The purpose of the present study is to build a model to determine the structure of long-term quasi-optimal rates of local and toll telephone services. The outline of this study is as follows : Telephone business, providing social goods, is capital-intensive industry which needs huge fixed cost to operate exchanges and telephone networks nationwide. The nature of above industry justifies the market structure of telephone business to be natural monopoly and makes a good reason for government's direct regulation, that is, price regulation. Three is a gap between the present rates and the quasi-optimal ones because some administrative processes intervene in rate making process before execution. On the above diagnostic basis, the present study made an empirical test for the optimality of present rates structure in connection with Ramsey-Boiteux model to maximize the sum of producer's and consumer's surplus and also the current study proposed a qusasi-optimal rates structure for better market performance. From the empirical analysis, we can deduce a policy recommendation the local price should be increased to 47% whereas toll price decreased to 24% in order to improve the net welfare worth of 32.6 billion won.

Due to the virtual nature of online businesses, online apparel stores need to enhance the consumer experience by utilizing store design attributes to provide their customers relevant and sufficient information. Since online apparel stores mainly communicate with their customers virtually and digitally, it is important to understand how consumers perceive and react to different design attributes commonly found on apparel stores' online websites. The purpose of this paper is to examine the importance of design attributes commonly found on online apparel stores' websites using three different importance measurements. The design attributes examined in this study include enlarged pictures, product detail pictures, product reviews by other buyers, coordinating items, and size measurement charts. The three different measurements used in this study include two direct measures and one indirect measure using conjoint analysis. Across the three different measures, both the men and women indicated that enlarged pictures represent the most important design attribute when they purchase clothes online followed by size measurement charts and they considered the availability of coordinating items the least important design attribute.

Currently, NAND Flash memory has been widely used in consumer storage devices due to its non-volatility, stability, economical feasibility, low power usage, durability, and high density. However, a high capacity of NAND flash memory causes the high power consumption and the low performance. In the convention memory research, a hierarchical filter mechanism can archive an effective performance improvement in terms of the power consumption. In order to attain the best filter structure for NAND flash memory, we selected a direct-mapped filter, a victim filter, a fully associative filter and a 4-way set associative filter for comparison in the performance analysis. According to the results of the simulation, the fully associative filter buffer with a 128byte fetching size can obtain the bet performance compared to another filter structures, and it can reduce the energy*delay product(EDP) by about 93% compared to the conventional NAND Flash memory.

Service industries are rapidly increased and the environment of service is also changing in healthcare settings. Those make them change their management strategies and carry out many researches. Till now, single-item behavioral intention scale or direct measuring has some limitations that we have to consider its efficiency and it is difficult to explain phenomena of broad part in the process of determining behavioral intentions. In this paper, we examine the dimensionality of healthcare service in Korea through the multi-item behavioral intention scale. In addition, we are going to investigate the nature of the relationship between service quality perceptions which have unique construct, and consumer satisfaction judgements in the formation of consumers' behavioral intentions. we are going to conclude that the linear combination model of service quality and customer satisfaction can describe the process of formation of customers' behavioral intentions best and provide some managerial implications to decision makers for redistribution of materials and human resources.

Theoretically and practically, it is very important to understand the way which tourist satisfaction is operated. The purpose of this study is to identify interaction among the determinants of tourist satisfacton process. A model of tourist satisfactioin process is developed based based on the confirmation / disconfirmation which is originated from consumer behavior literature. Three elements of the model include 'expectation','performance', and 'discrepancy between expectation and performance'. 340 questionnaires were delivered to find Everland visitors' perceptions of the determinants of tourist satisfaction. LISREL 8.14 was used to analyze the interaction among the determinants. The results are as follows : 1) 'expectation' has indirect effect on tourist satisfaction while 'performance' and 'discrepancy' has direct effect on the tourist satisfaction, 2) two precedent variables such as 'expectation' and 'performance' have indirect effect on the satisfaction through 'discrepancy',3) among the three determinants it is found that 'performance' is the most effective determinant of tourist satifaction, and 4) the model which was composed from the aspect of 'travel cost' was more effective to describing tourist satisfacton rather that from the aspect of 'service quality'.

As digital advertising continues to dominate the advertising industry and experience substantial growth, associated criminal activities such as advertising fraud and brand safety risks have become increasingly prevalent. Despite the severity and extent of these crimes, the response in Korea has been lackluster, often perceiving them merely as losses in advertising expenses incurred by corporations. However, it is important to note that these issues have direct repercussions on the end-consumer in the form of increased prices for goods and services. Furthermore, illegal and intrusive advertisements not only cause inconvenience to the viewer, but may also indiscriminately target cognitively vulnerable groups, such as children and the elderly, with the intention of manipulating advertising metrics and artificially inflating performance indicators. In this study, we aim to explore the concept and significance of advertising fraud and brand safety, and to evaluate the current measures taken in the Korean market. Additionally, we will delve into the implications of related policies and emphasize the necessity of digital advertising literacy in addressing these issues.

Based on the theory of planned behavior, this study aims to examine the structural equation model among consumers' concerns and purchase intentions for alternative meats. Data were collected from 300 adults living in Kyeonggi Province. Results show that animal welfare, environmental concern, and health concern all have a direct and significant effect on purchase intention of alternative meat, and the mediation effect is also significant, indicating a partial mediation effect. The image of a company as caring about animal welfare and contributing to public causes can help sell alternative meats. Media publicity focusing on animal welfare for alternative meats can improve the attitudes of domestic consumers as well as their intention to purchase alternative meat products.

The purpose of this study is to present a plan to activate the production and consumption of environmently friendly agricultural products through an analysis on the understanding degree, the level and inclination of consumption, the satisfaction degree of consumption, and the comprehension degree of production and circulation process of the environmently friendly agricultural products. 1 reviewed the literature and did survey In this study. The results are as follows : (1) As a result of an analysis on the understanding degree of the environmently friendly agricultural products, it is shown to get 6.37 points out of 10 and also, there is a difference between age, educational background, and income level. (2) In the case of research on the method to distinguish the environmently friendly agricultural products from others, it is proved that consumers have a strong faith on quality guarantee marks and there is a difference between gender, income level, and consumption period. (3) It is also shown that consumers purchase environmently friendly agricultural products for the family member's health in the survey on the motivation for purchasing them. And also, there is a difference between men and women. (4) The result of the survey on the consumption scale of the environmently friendly agricultural products shows that 94 people(60.3％) spend more than 50％ of their gloss foodstuffs cost purchasing them and 20 people(12.8％) spend 30-50％. (5) In the survey on the amount and the frequency of the purchasing items of the envirounently friendly agricultural products, respondents count livestock products mostly in amount while point out main cereals and a kinds of soy and pastes in frequency. (6) Consumers ask that the price of environmently friendly agricultural products is a little expensive or reasonable and there is no differences between individual groups. (7) In the case of the purchase of foreign environmently friendly agricultural products, there are more people who want to purchase domestic ones than those who want foreign ones. Therefore, it is shown that environmently friendly agricultural products have a counterpower after the market-open to import. (8) As a result of the analysis on the quality of environmently friendly agricultural products, it is proved that they have better quality than general agricultural products and also, it is found out that women feel larger differences than men in quality. (9) In the analysis on the satisfaction degree of the environmently friendly agricultural products, it is proved that respondents trust the safety and nutrition of them whereas they are not satisfied with the external shape of them. (10) It is analyzed that tile conversion of consumer's consciousness is the most critical factor for development of environmently friendly agriculture. (11) The factors to activate the consumption of environmently friendly agricultural products are proved in order of the enlargement of direct transaction, the conversion of consumer's consciousness, the easiness of purchase, activating consumers'unions, and publicity.
