Advances in Internet technologies and the proliferation of mobile devices enabled consumers to approach a wide range of goods and services, while causing an adverse effect that they have hard time reaching their congenial items even if they devote much time to searching for them. Accordingly, businesses are using the recommender systems to provide tools for consumers to find the desired items more easily. Association Rule Mining (ARM) technology is advantageous to recommender systems in that ARM provides intuitive form of a rule with interestingness measures (support, confidence, and lift) describing the relationship between items. Given an item, its relevant items can be distinguished with the help of the measures that show the strength of relationship between items. Based on the strength, the most pertinent items can be chosen among other items and exposed to a given item's web page. However, the diversity of the measures may confuse which items are more recommendable. Given two rules, for example, one rule's support and confidence may not be concurrently superior to the other rule's. Such discrepancy of the measures in distinguishing one rule's superiority from other rules may cause difficulty in selecting proper items for recommendation. In addition, in an online environment where a web page or mobile screen can provide a limited number of recommendations that attract consumer interest, the prudent selection of items to be included in the list of recommendations is very important. The exposure of items of little interest may lead consumers to ignore the recommendations. Then, such consumers will possibly not pay attention to other forms of marketing activities. Therefore, the measures should be aligned with the probability of consumer's acceptance of recommendations. For this reason, this study proposes a model-based approach to combine those measures into one unified measure that can consistently determine the ranking of recommended items. A regression model was designed to describe how well the measures (independent variables; i.e., support, confidence, and lift) explain consumer's acceptance of recommendations (dependent variables, hit rate of recommended items). The model is intuitive to understand and easy to use in that the equation consists of the commonly used measures for ARM and can be used in the estimation of hit rates. The experiment using transaction data from one of the Korea's largest online shopping malls was conducted to show that the proposed model can improve the hit rates of recommendations. From the top of the list to 13th place, recommended items in the higher rakings from the proposed model show the higher hit rates than those from the competitive model's. The result shows that the proposed model's performance is superior to the competitive model's in online recommendation environment. In a web page, consumers are provided around ten recommendations with which the proposed model outperforms. Moreover, a mobile device cannot expose many items simultaneously due to its limited screen size. Therefore, the result shows that the newly devised recommendation technique is suitable for the mobile recommender systems. While this study has been conducted to cover the cross-selling in online shopping malls that handle merchandise, the proposed method can be expected to be applied in various situations under which association rules apply. For example, this model can be applied to medical diagnostic systems that predict candidate diseases from a patient's symptoms. To increase the efficiency of the model, additional variables will need to be considered for the elaboration of the model in future studies. For example, price can be a good candidate for an explanatory variable because it has a major impact on consumer purchase decisions. If the prices of recommended items are much higher than the items in which a consumer is interested, the consumer may hesitate to accept the recommendations.
The goal of medicine is to contribute to promoting national health by preventing diseases and providing treatment. The scope of modern medicine isn't merely confined to disease testing, treatment and prevention in accordance to that, and making experiments by using the human body is widespread. The advance in modern medicine has made a great contribution to valuing human dignity and actualizing a manly life, but there is a problem that has still nagged modern medicine: treatment and healing for terminal patients including cancer patients. In advanced countries, pain care and hospice medicine are already universal. Offering a helping hand for terminal patients to lead a less painful and more manly life from diverse angles instead of merely focusing on treatment is called the very hospice medicine. That is a comprehensive package of medical services to take care of death-facing terminal patients and their families with affection. That is providing physical, mental and social support for the patients to pass away in peace after living a dignified and decent life, and that is comforting their bereaved families. The National Hospice Organization of the United States provides terminal patients and their families with sustained hospital care and home care in a move to lend assistance to them. In our country, however, tertiary medical institutions simply provide medical care for terminal patients to extend their lives, and there are few institutional efforts to help them. Hospice medicine is offered mostly in our country by non- professionals including doctors, nurses, social workers, pastors or physical therapists. Terminal patients' needs cannot be satisfied in the same manner as those of other patients, and it's needed to take a different approach to their treatment as well. Nevertheless, the focus of medical care is still placed on treatment only, which should be taken seriously. Ministry for Health, Welfare & Family Affairs and Health Insurance Review & Assessment Service held a public hearing on May 21, 2008, on the cost of hospice care, quality control and demonstration project to gather extensive opinions from the academic community, experts and consumer groups to draw up plans about manpower supply, facilities and demonstration project, but the institutions are not going to work on hospice education, securement of facilities and relevant legislation. In 2002, Ministry for Health, Welfare & Family Affairs made an official announcement to introduce a hospice nurse system to nurture nurse specialists in this area. That ministry legislated for the qualifications of advanced nurse practitioner and a hospice nurse system(Article 24 and 2 in Enforcement Regulations for the Medical Law), but few specific plans are under way to carry out the regulations. It's well known that the medical law defines a nurse as a professional health care worker, and there is a move to draw a line between the responsibilities of doctors and those of nurses in association with medical errors. Specifically, the roles of professional hospice are increasingly expected to be accentuated in conjunction with treatment for terminal patients, and it seems that delving into possible problems with the job performance of nurses and coming up with workable countermeasures are what scholars of conscience should do in an effort to contribute to the development of medicine and the realization of a dignified and manly life.
The skyrocketing inflation of medical costs has become a major health problem among most developed countries. Korea, which recently covered the entire population with National Health Insurance, is facing the same problem. The proportion of health expenditure to GNP has increased from 3% to 4.8% during the last decade. This was remarkable, if we consider the rapid economic growth during that time. A few policy analysts began to raise cost containment as an agenda, after recognizing the importance of medical cost inflation. In order to Prepare an appropriate alternative for the agenda, it is necessary to find out reasons for the cost inflation. Then, we should focus on the reasons which are controllable, and those whose control are socially desirable. This study is designed to articulate the theory of medical cost inflation through literature reviews, to find out reasons for cost inflation, by analyzing aggregated data with a deterministic model. Finally to identify determinants of changes in both medical demand and service intensity which are major reasons for cost inflation. The reasons for cost inflation are classified into cost push inflation and demand pull inflation, The former consists of increases in price and intensity of services, while the latter is made of consumer derived demand and supplier induced demand. We used a time series (1983-1987), and cross sectional (over regions) data of health insurance. The deterministic model reveals, that an increase in service intensity is a major cause of inflation in the case of inpatient care, while, more utilization, is a primary attribute in the case of physician visits. Multiple regression analysis shows that an increase in hospital beds is a leading explanatory variable for the increase in hospital care. It also reveals, that an introduction of a deductible clause, an increase in hospital beds and degree of urbanization, are statistically significant variables explaining physician visits. The results are consistent with the existing theory, The magnitude of service intensity is influenced by the level of co-payment, the proportion of old age and an increase in co-payment. In short, an increase in co-payment reduced the utilization, but it induced more intensities or services. We can conclude that the strict fee regulation or increase in the level of co-payment can not be an effective measure for cost containment under the fee for service system. Because the provider can react against the regulation by inducing more services.
Social development as well as the development of consumer electronic devices due to leakage, electric shock or fire, and many are exposed to the risk of leakage currents. Premises in the control cabinet, but the circuit breaker is installed, the existing circuit breaker shuts off when a short circuit in the control cabinet, installed only have the capability. Also connected to the outlet is installed byeokmada family of devices is not easy thing to check individually. In this paper, circuit breakers and circuit analysis and circuit performance, ZigBee-based premises of consumer electronics devices using sensors to monitor the health of the leakage can be presented on how. Performance analysis, the proposed ELB leakage current control system is built into the appliance leakage circuit breaker for each household appliances because the application can check the status of a short circuit, short circuit, over the existing system can be monitored easily.
This research is designed for a consumer, not a supplier when it was designed. And the purpose is to present the reference data which is in order to improve the curriculum by analyzing the present subject of the curriculum. The research collected the curriculum for Dental Technology from a total of 20 schools --3-year colleges and 4-year colleges-- all in Korea. And we analyzed the average credits of subjects from students. As a result of this analysis, we get the conclusion below: 1. In a distribution which students answered about each subjects; Dental esthetic, Dental morphology I II, Dental morphology practice I II, and Seminar don't have many credits and mostly have a converged tendency in high points, according to the arithmetic mean of the major basis subjects. 2. In an analysis of the correlation which is based on the distinction of sex; Dental ceramics practice III, Medical terminology, Seminar, and The major basis subjects have a meaningful difference. (${\rho}$ < 0.05) 3. In an analysis of the correlation which is based on an age; The major basis subjects, and the application subjects have meaningful difference. (${\rho}$ < 0.05) 4. In a correlation coefficient between subjects; The correlation coefficient of the major application subjects is higher than the major basis subjects. According to the student ? t, we found that the level of significance is ${\rho}$ < 0.001, which is meaningful. We feel that Department of Dental Technology also highly need to design, and conduct focusing on a consumer who is working at the society, not a supplier. And we need to increase or decrease credits which have a meaningful difference.
This study intended to identify how our children are aware of dental health and motivate them to learn reasonable knowledge about dental health. Furthermore, it also aimed to induce them to change their awareness and behavioral style about dental health, so that they may keep good habits for dental health for their lifetime. Total 1,044 samples were collected from children who were all 12 years old and lived in Seongnam city. During six months (June to December 2002), they were asked to participate in questionnaire survey about consumer behavior, knowledge, attitude, activity and self-diagnosis for dental health. The results of questionnaire survey can be outlined as follows: (1) The results of investigating consumer behavior for dental health showed that 34.5% of total respondents ever visited dental clinics once or more within latest one year, 21.4% ever visited dental clinics for the sake of prevention, 70.6% were instructed in dental health program, 31.7% were treated with the fluorination, 36.9% were treated with dental sealant, and 17.1% were treated with scaling, respectively. (2) For 10 items asking reasonable knowledge about dental health, respondents answered to 5.06 items on average. (3) For 10 items asking reasonable attitude for dental health, respondents answered to 5.41 items on average. (4) For 10 items asking reasonable behavior, respondents answered to 4.53 items. (5) For 10 items asking reasonable self-diagnosis for dental health, respondents answered to 5.65 items.
CALS/EC is about doing business electronically. It is based on the electronic processing and transmission of data, including text, sound and video. It encompasses many diverse activities including electronic trading of goods and services, online delivery of digital content, electronic fund transfers, electronic share trading, electronic bills of lading, commercial auctions, collaborative design and engineering, online sourcing, public procuremet, direct consumer marketing, and after-sales service. It involves both products(e.g. consumer goods, specialised medical equipment) and services(e.g. information services, financial and legal services); traditional activities(e.g. healthcare, education) and new activities (e.g. virtual malls). CALS/EC will be emerging to replace and substitute the role of the conventional market. By changing and eliminating some processes of the transactions, the electronic market and the electronic commerce will redistribute the power and hence the benefits of the market activities. Traditional way of doing business may enter into the new electronic market because the role and function of trust and established reputation will be reinforced in the electronic market. The CALS/EC through the Internet has been in the spotlight in the shopping behavior of the consumers. Accordingly Corporates are trying to adapt themselves to those rapidly changing environments being affected by the Internet. Among others, particularly to be noted is the CALS/EC between corporations and consumers whose potential growth can be considered very substantial. This report, focusing on the introduction of CALS/EC for the logistics of SMEs, will allow us to prepare more efficiently for the coming 21st Century. It is obvious that CALS/EC is fast becoming the useful way of exchanging not only information but products in business between firm-to-firm and firm-to-customer.

The purpose of this study was to identify the present use of caregiver services, to evaluate the degree of satisfaction with the services according to type of caregiver service, private or public, and to provide data for the development of a plan which will provide good quality service with less economic and psychological burden to the patients and their families. Survey data were collected from 130 patients in 4 general hospitals in Seoul, and their families. Data were collected during April, 2004, using a questionnaire which included the patient satisfaction scale developed by Jun (2001). Data were analyzed using frequencies, percentages, means and standard deviations, $X^2$ analysis, t-test. The SPSS computer program was used to facilitate analysis. The results of this study are summarized as follows; The total score for satisfaction was high for both groups. For the private caregiver group it was $52.38{\pm}11.08$, and for the public caregiver group, $58.14{\pm}9.64$. This difference was significant(t=-3.391, p=.001). In all of areas, the scores for satisfaction of the public caregiver service group were higher than private caregiver service group, ie. caregivers' attitude, role, confidence, performance, and service charge, and all the differences were significant. In conclusion, it was found that long-term hospitalization of older patients with high dependence resulted in more caregiver service. There were more severe patients in the public caregiver group, but the service charges, additional costs and paid holidays were less. Based on these results, patients and their families were significantly more satisfied with public caregiver service because it was not only less expensive but also had a high quality of service. Thus, caregiver services should be systemized so that patients and their families will get the best quality caregiver service
