Recently, the problem of air pollution has become a global concern due to industrialization and overcrowding. Air pollution can cause various adverse effects on human health, among which respiratory diseases such as asthma, which have been of interest in this study, can be directly affected. Previous studies have used clinical data to identify how air pollutant affect diseases such as asthma based on relatively small samples. This is high likely to result in inconsistent results for each collection samples, and has significant limitations in that research is difficult for anyone other than the medical profession. In this study, the main focus was on predicting the actual asthmatic occurrence, based on data on the atmospheric environment data released by the government and the frequency of asthma outbreaks. First of all, this study verified the significant effects of each air pollutant with a time lag on the outbreak of asthma through the time-lag Pearson Correlation Coefficient. Second, train data built on the basis of verification results are utilized in Deep Learning algorithms, and models optimized for predicting the asthmatic occurrence are designed. The average error rate of the model was about 11.86%, indicating superior performance compared to other machine learning-based algorithms. The proposed model can be used for efficiency in the national insurance system and health budget management, and can also provide efficiency in the deployment and supply of medical personnel in hospitals. And it can also contribute to the promotion of national health through early warning of the risk of outbreak by atmospheric environment for chronic asthma patients.

This study suggest a model to find out relationships among the servant leadership as a preceding factor, the trust in higher officers as mediating factors, and leader satisfaction, additional efforts as a resulting factor. Then, empirical study testify the relationship among these factors. This study confined the subjects of empirical analysis to the employees in super-deluxe hotels located in Seoul, Gyeongju, Busan, and Daegu areas. In order to clarify the utility of this study, This study took only hotel employees as the subject of measurement because only hotel organization is able to reveal sensitively the behavioral response between the leader and the members of organization. The preceding study has systematized a basic theory on the servant leadership, and provided factor structure in regard to the servant leadership, but this study has searched the factor structure of the servant leadership with the hotel employees as the subjects of study. Also, from the side of the personnel manager of hotel business, this study can be a criterion for clarifying a leadership program. Especially, in order to cultivate their servant leadership, it is necessary to testify morality and pride as sub-behavioral characteristics of new employees. Also to change the mid-managers' leadership for the effective achievement of the object of organization, this study can be utilized for the development of servant leadership.

The Hospitalized Acquired Infection is defined as the case where the hidden infection or not found at the time of hospitalization occurs during the hospitalized period or, within 30 days to those who performed the surgery operation and then left the hospital. About 2/3 of the Hospitalized Acquired Infection are found as having the internal infection cases that are occurred by the patients' own virus due to the lowered immune system, while about 1/3 are found as having the external infection. The latter 1/3 of the external infection cases can be prevented through the infection management. And in case the new Hospitalized Acquired Infection case occur to the patient who was treated in the hospital, its responsibility issue will matter. As well in the disputes over the Hospitalized Acquired Infection cases, the cause-result relation between the damages and the medical staff's fault and as to whether there is failure of the medical staff or not. personnel should be proved in the medical-malpractice cases. In addition, the difficulties in proving such as expertise, secrecy propensity, discrete propensity and incompleteness will be considered to ease the burden of patient side's proving. Probability theory, Fact based assumption theory, Most adequate plaintiff preassumption or Expressed evidence theories are being discussed as the theories of eased burden of proof. In the result of gathering and reviewing Korea's precedent cases concerning the Hospitalized Acquired Infection, there are only a few accumulated prece dent cases and the attitude of the court also are also not consistent. Therefore, there are the precedents where the cause-result relation and the failure are immediately assumed when (1) timely proximity between the medical behavior and malpractice results, (2) proximity between the medical behavior-applied parts and the malpractice results-found parts, and (3) lack of other causes are separately evidenced; while the are the precedents only when 'the existence of the medical faults based on the common sense' is separately evidenced. It was found that the former and latter cases coexisted. The former is considered as based on the theory that separates the fault and cause-result relation not to consider them together, or regarded as based on the doubts that assumes the medical staff's neglect even though the Hospitalized Acquired Infection might be completely prevented by their efforts. However, the modern medical technology has the limitation as far as the prevention of the Hospitalized Acquired Infection. In conclusion, the assumption of the cause-result relation and that of the fault should be separately reviewed. Therefore, the latter precedents are considered as more reasonable, in the point the faulty behavior may be proved based on the common sense.

Objectives: This study aimed to determine the effects on musculoskeletal symptoms of both social demographic features and detailed characteristics of each task category of care workers who offer visiting home-help services. And to establish the measures that can reduce musculoskeletal symptoms among care workers. Methods: This study was conducted among 192 care workers from welfare centers C and K located in city P. After participants completed the task burden checklist regarding the scale of musculoskeletal symptoms and the details of their duties, the data collected were analyzed using the SPSS 21.0 program. Results: According to the degree of observable musculoskeletal symptoms in care workers, the highest figures were observed for back and shoulder pain. Based on the results of assessing the effect of detailed task category characteristics on musculoskeletal symptoms, "helping patients eat, helping patients move, helping patients bath, and changing body positions" were found to have an effect from the physical care category, "providing physical therapy assistance, treating bedsores" from the health care category, and "cleaning and doing laundry" from the facility management category. Conclusions: Due to the high proportion of patients requiring burdensome physical labor from care workers such as moving patients who have trouble doing so on their own, helping them change positions, and so on, it is highly likely that pain will occur in the low back, which carries most of the physical weight. So, education on human epidemiological positions that can reduce overload on areas prone to pain such as the low back and shoulders is essential. Proper equipment and personnel support must be provided for dangerous tasks. Further, multidimensional social support is required consistently.

The surgical hand scrub (SHS) is the single most important procedure in the prevention of post-operative wound infections and yet it remains the most violated of all infection control procedures. The purpose of this study was to gain an overview of SHS habits in operative th atre personnel and to determine knowledge and attitudes to identify whether there is a need for improvement. The subjects for this study included 79 doctors and 94 nurses working in the operative th atres of four hospitals in Incheon City and Kyungki Province. Related data were collected from July 25 to August 10, 1995 by the author. The data were analyzed using descriptive stat-istics and Chi-squre test. The results of the study are summarized as follows : 1. Nurses felt that they conducted SHS for a longer period of time than doctors did(X=20.1, P=.005). 2. Nurses and doctors had some knowledge of slip-ping rings off fingers and the length of nails, but they lacked knowledge on the duration of SHS, handwashing after an operation and on manicure. 3. There were many reasons given for insufficient SHS included : 1) because they were so busy (38%). 2) brushes were too harsh(19.7%). 3) operations were very simple(18.7%). 4) surgical latex gloves provide functional barrier(11.6%). 5) SHSs were troublesome(7.4%) 6) there were no clocks near the sinks(2.5%) and 7) the operative patients were administered antibiotics after operartion(2.1%). 4. Most of nurses and doctors considered SHS to be important in prevention against post operative infections. 5. Nurses were found to do a thorough SHS, but residents were found to neglect SHS. 6. Considering prevention against postoperative infections, most nurses and doctors considered aseptic techniques, environment-sanitary management and SHS more important than the use of antibiotics, the resistance of patients or the method of operation. 7. Half of the nurses and doctors(54.3%) considered surgical latex gloves to function well as a barrier. 8. Half of the nurses (56.4%) and doctors(51.9%) learned SHS as part of the curriculum in their school education and the rest(nurses : 95.7%, doctors : 74.7%) learned SHS as part of their In Service Education. In conclusion, these findings suggest a need to develop an educational program on surgical hand scrub and hospital infection control for surgical personnels, to install clocks near the hand scrub sinks, to consider a violation report for negligent surgical hand scrubs, and to develop a soft brush for hand scrubs in order to increase performance of the surgical hand scrub.

There are about 22,000 national control points throughout this nation. However, in order to identify the location data of a national control point, a control point result table is needed. And although the control points are important national facilities, due to the fact that these points located at remote areas such as on top of mountains, the facilities are being maintained via on-site inspection without any protections around them. In this research, by taking the locations where the control points are placed into consideration, a specialized RFID tags that can be attached to the national control point's marker has been developed, and CDMA-ready PDA based mobile Web System and national control point control system are developed as well. With help of these systems, control point data can be checked at the seen, and national control point maintenance personnel can find out about maintenance status and keep track of usage record. When these systems are taken into effect, access to the national control point data becomes easy, fast response to the change in data can be possible, and management efficiency will go up. When the Ubiquitous society becomes reality, the importance of location information will be high. Therefore, national control points using above mentioned RFID tags will not only be useful to the control point users and maintenance personnels such as professional land surveyors, but also useful when providing location based services to people, and it will become an important national infrastructure in terms of providing absolute location information.

Despite the rapid growth and importance of social enterprises in recent years, most social enterprises have many limitations such as small business size, financial dependence on government, lack of professional management personnel and knowledge, and low consumer awareness. Therefore, empirical research in the field of marketing is needed for economic independence of social enterprises. This study is based on the following: First, the identity of the social enterprise and the self-image of the consumer, second, the functional correspondence between the consumer's expectation and actual performance of the social enterprise's product, and third, the social value of the social enterprise product, the purpose of this study was to examine the effects of consumer value consistency on customer satisfaction and loyalty to social enterprises. Finally, this study aimed to suggest the moderating role of social enterprise clubs in this process to give implications for the long-term marketing of social enterprises. The results of this study are as follows. First, self-image consistency, functional correspondence, and value correspondence all have positive effects on the satisfaction of social enterprise and its products and form a loyalty. Secondly, whether or not the social enterprise club belonged to them is a moderating variable that raises sensitivity in the effects of self image consistency and functional consistency on customer satisfaction and customer satisfaction on loyalty. It was found to be.

The value of personal information is increasing with the digital transformation of the 4th Industrial Revolution. The purpose of this study is to analyze the efficiency of personal information protection efforts of 2,000 private companies. It uses a stochastic frontier approach (SFA), a parametric estimation method that measures the absolute efficiency of protective activities. In particular, the personal information activity index is used as an output variable for efficiency analysis, with the personal information protection budget and number of personnel utilized as input variables. As a result of the analysis, efficiency is found to range from a minimum of 0.466 to a maximum of 0.949, and overall average efficiency is 0.818 (81.8%). The main causes of inefficiency include non-fulfillment of personal information management measures, lack of system for promoting personal information protection education, and non-fulfillment of obligations related to CCTV. Policy support is needed to implement safety measures and perform personal information encryption, especially customized support for small and medium-sized enterprises.
