With recent news reports on violent crimes committed by foreigners, public hatred toward foreign criminals and fear about such crimes are growing, calling into question public safety measures implemented by the police and the immigration system. At the same time, due to globalization and structural changes in the labor market, it is certain that the influx of migrant workers will continue to increase. Against this backdrop, this paper seeks to examine the current status of foreign nationals staying in Korea and their criminal records focusing on Suwon city, and propose public safety measures the police could take with regard to crimes committed by foreigners. Also, the paper looks into public safety measures of the Korea Immigration Service and Suwon city, and suggests short- and long-term measures to prevent crimes committed by foreigners. The paper begins by examining the current public safety measures of the police and Suwon City concerning crimes committed by foreign nationals residing in Korea. Based on such examination, it points out insufficient patrol and investigation personnel as problems, and recommends short- and long-term measures for future improvement. This paper maintains that for the Korean society to successfully deal with the increasing number of foreigners in Korea, the current immigration system and public safety measures of the police will have to change. While the police alone cannot reduce the crime rates at local and national levels, nonetheless, proactive measures by the police are needed given the growing number of migrant workers and immigrants in Korea. Also important are mindset changes not only of relevant authorities, but also of the public. The paper recommends a set of short-and long-term public safety measures the police should institute to efficiently deal with crimes committed by foreigners.

Even though the notion exists that wall paper has got a short durability for interior decoration in terms of paper's nature, it can be the most important element among the modern dosing wall papering because of the variation of the walls visual effect. Wall paper hasn't been preserved well according to the paper's character and official records haven't been done well. So, by studying a case in which a room is maintained well, seeing various commercial samples which were used for an advertisement and reading several booklets it is possible to study historical evidence. In regard to wall paper and Papering. data, the commercial historic nature of the traditional wall papering has been recognized again in order to study the root of the technical and commercial background. In theory, the historic background research of traditional wall paper in the past is said to have established its theoretical system and the development of modern wall papering in the middle of Britain in 18th century. Through the theoretical study of wall papering, the following things have been researched: handling don the method of the traditional wall papering and lining paper, stylization of pattern by using the method of continual linking, subdivision of commercial cost and specialization of wallpaper, handing down the past traditional adhesion method, the origin of string wallpaper, utility of traditional wallpaper and its various abilities, the change from the face to face linking to duplicated linking, the development of DIY products by women's wallpaper selections. Put against other materials, wallpaper remains the most popular and preferable product for managing a wall and provides a decorative, wall dosing technique. This study can estimate the source of wallpapering history in order to create a systemic approach towards the future's wallpaper industry. This is very important data in order to establish a theoretical system of traditional wallpapering according to its historical research about wallpapering skills and its commercial aspect.

Objectives : A protocol called "critical pathway" was developed to standardize the management of hospital patients the day after they underwent gamma knife radiosurgery. The quality of improvement in patient outcomes was evaluated. Methods : Critical pathway was developed, according to the regulations of the I hospital, by analyzing the medical records of 22 inpatients who underwent gamma knife surgery within the period from January to April 2011 on the day of the surgery. The study included a group of 22 patients admitted to the hospital the day after they underwent gamma knife radiosurgery, between July and September 2011. The control group included 22 patients who had surgery employing the same method within the period from May to June 2011. To measure the effects on quality improvement, the average length of stay, the execution rate of the hospital discharge notice system, daily hospital revenue, and the satisfaction of the patients and the medical team were assessed. The patient questionnaire employed a four-point Likert scale while the medical-staff questionnaire employed a five-point Likert scale. Result : The average length of stay was significantly shorter in the study group compared to the control group (2.3 days vs. 3.8 days, P<0.05). The execution rate of the hospital discharge notice system was higher in the study group (100% vs. 72%) than in the control group. Daily hospital revenues were higher by 264,178 Korean won in the study group when compared to the control group. The study group showed greater satisfaction of patients compared to the control group based on a four-point Likert scale (P<0.05). The study group showed greater satisfaction in medical team compared to the control group based on a five-point Likert scale (P<0.05). Conclusion : The development and implementation of a critical pathway protocol for hospital admission the day after gamma knife radiosurgery is an effective care process that improves the clinical quality.

This paper proposes a restoration scheme based on mobility learning and prediction in the presence of the failure of mobility databases in mobile communication systems. In mobile communication systems, mobility databases must maintain the current location information of users to provide a fast connection for them. However, the failure of mobility databases may cause some location information to be lost. As a result, without an explicit restoration procedure, incoming calls to users may be rejected. Therefore, an explicit restoration scheme against the failure of mobility databases is needed to guarantee continuous service availability to users. Introducing mobility learning and prediction into the restoration process allows systems to locate users after a failure of mobility databases. In failure-free operations, the movement patterns of users are learned by a Neuro-Fuzzy Inference System (NFIS). After a failure, an inference process of the NFIS is initiated and the users' future location is predicted. This is used to locate lost users after a failure. This proposal differs from previous approaches using checkpoint because it does not need a backup process nor additional storage space to store checkpoint information. In addition, simulations show that our proposal can reduce the cost needed to restore the location records of lost users after a failure when compared to the checkpointing scheme

The recent development of embodiment technology of the medical images makes most medical institutions introduce PACS(Picture Archiving and Communication System) in haste. However lots of PACS solutions, currently developed and distributed, haven't been able to serve the convenience of users and to satisfy user's demand because of economic limitations and administrator-oriented considerations in the process of development. So we have developed MIH(Medical Image History), by which we can search and refer to the patient's medical images and information with few restrictions of time and space for diagnosis and treatment. This program will contribute to the improvement in the medical environment and meet the clients' need. We'll make more effort to develop the application which insures the better quality of medical images. MIH manages the patient's image files and medical records like film chart in connection with time. This trial will contribute to the reduction of the economical loss caused by unnecessary references and improve the quality in the medical services. The demand on the development or the program which refers to the medical +ata quickly and keeps them stable will be continued by the medical institute. This will satisfy the client's demand and improve the service to the patients in that tile program will be modified from the standpoint of the users. MIH is trying to keep user-oriented policy and to apply the benefit of the analog system to the digital environment. It is necessary to lead the public to the better understanding that the systematic management and referring of the medical images is as important as the quality of the images.

Purpose: This study was aimed to investigate the contamination rates of blood culture in a neonatal intensive care unit (NICU) and to examine the clinical characteristics related to the contamination. Methods: Eight hundred thirty cases of blood culture performed from March 2013 to February 2014 were analyzed. We evaluated the contamination rates of blood culture by blood sampling sites and compared the clinical characteristics such as real name system and body weights of the contaminated cases and those of non-contaminated ones. The clinical characteristics were retrospectively reviewed by medical records. Results: The overall contamination rate was 3.6% (30/830). The contamination rates by blood sampling sites were as follows: peripheral vein 15.6% (10/64), peripheral artery 2.6% (20/759), and umbilical arterial catheter 0% (0/7). There was no difference in the contamination rates between cases with and without real name system (P=0.484). However, there were significant differences in the contamination rates by the physicians who performed the culture (P=0.038) and body weight (<1,000 g vs. ${\geq}1,000g$) at the time of blood culture (P<0.001). Conclusions: These results suggest that neonates with a body weight less than 1,000 g have more risks of the contamination of blood culture. Furthermore, there is a necessity to provide blood culture performers with active feedbacks and individualized education plans that can help diminish blood culture contamination rates. Prospective studies in a systematic manner that can be applied in actual clinical settings are needed in order to figure out factors that can diminish the contamination rates of blood culture in NICU.

Objectives : To evaluate the annual visit days, the annual prescription days and the medical costs of hypertensive patients. Methods : The medical insurance records of 40,267 incident patients with the diagnostic code of hypertension from September 1998 through August 1999 in Daegu city were reviewed. Results : The proportion of the most proper medical care pattern group (Group VIII) who visited for 6-15 days with 240 prescription days or more a year was only 6.2%. The proper care group (Group IX) who visited for more than 16 days with 240 prescription days or more a year was 9.3%. The overall proper care group (Group VIII+IX) was therefore 15.5%. The proportion of the insufficient care group (Group I, IV) in both the number of visiting days and prescription days was 57.4%. The mean prescription day of the most proper group (Group VIII) was 29 days; the mean annual medical expenses,453,587won; the mean annual amount paid by patients, 218,013won; and mean medical expenses per prescription day, 1,483won. The proportion of the overall proper care group (Group VIII+IX) was significantly higher in adults aged 50-59, those who were enrolled in industrial workers health insurance as well as government employees and private school teachers health insurance, and those who made a higher contribution per month (p<0.01). According to the type of medical facilities, the proportion of the most proper medical care pattern group was highest in the general hospitals (9.3%) but the overall proper care group was higher in the public health centers (22.1%) and private clinics (17.1%). Conclusions : The management system of hypertension should be reinforced urgently. Therefore, it is necessary to develop guidelines including the number of visiting days per year and prescription days per visit day, and make the system provide medical facilities to more properly care for hypertensive patients.

Objectives : The aim of this study is to identify factors determining the purchase of private health insurance under the mandatory National Health Insurance(NHI) system in Korea. Methods : The data were collected by the National Cancer Center in Korea. It includes cancer patients who were newly diagnosed with stomach (ICD code, C16), lung(C33-C34), liver (C22), colorectal cancer(C18-C20) or breast(C50) cancer. Data were gathered from the hospital Order Communication System (OCS), medical records, and face-to-face interviews, using a structured questionnaire. Clinical, socio-demographic and private health insurance related factors were also gathered. Results : Overall, 43.9% of patients had purchased one or more private health insurance schemes related to cancer, with an average monthly premium of \65,311 and an average benefit amount of \19million. Females, younger aged, high income earners, national health insurers and metropolitan citizens were more likely to purchase private health insurance than their counterparts. Conclusions : About half of Korean people have supple-mentary private health insurance and their benefits are sufficient to cover the out-of-pocket fees required for cancer treatment, but inequality remains in the purchase of private health insurance. Further studies are needed to investigate the impacts of private health insurance on NHI, and the relationship between cancer patients' burden and benefits.

This study set out to analyze the perceptions of investigative police officers and division police officers regarding Police Investigation Specialization, which had been in effect for four years, identify the problems, and search for alternative policies. The results led to the following alternative policies; first, the communication among the members should be facilitated by trading the jobs between investigative policemen and division members in certain percentage regularly, integrating job education and special work, and developing diverse support programs for detective activities to provide them with opportunities to experience and understand investigation. The second suggestion concerns the investigation members' morale. There should be a range of measures to boost their moral such as allocating separate budget and personnel to support the investigation department and the treatment of major criminal and civil cases, giving each investigation team an office and investigation room to improve their working environment, readjusting the promotion ratio of Police Investigation Specialization to introduce a promotion system proper for each investigation's characteristics. The third suggestion is to secure job efficiency. It's required to reinforce the current short-term specialized education program to bring up practical and professional investigators, open the certification exam of professional investigators to all members so that every policeman can have their abilities recognized and approved as long as they have the demanded capabilities, and create a system of shedding off the members idle at work by reflecting low performance records when evaluating the members to decide who to dismiss from Police Investigation Specialization. And finally, it's important to divide duties rationally. The rationality of duties division can be guaranteed by setting the guidelines for direct handling for the team leader to help him devote himself to his duties, defining objective criteria of measuring investigation workload, and creating devoted systems and teams for simple and small accidents so that experienced investigators can deal with high-profile cases.

Objectives This study aims to provide directions for future Korean pediatric medicine treatment and researches by analyzing the characteristics of diseases of Korean pediatric outpatients before and after the COVID-19 epidemic. Methods We analyzed the medical records of 10,868 new patients aged 0-18 who visited the Korean pediatrics at Kyung Hee university hospital from January 1, 2019 to June 30, 2021. All patients were divided into 2 groups; patients who visited from January 1, 2019 to December 31, 2019, before the coronavirus epidemic, and patients who visited from January 1, 2020 to June 30, 2021, after the coronavirus epidemic. Within the two groups, the diagnosis distribution was performed for the entire population, by gender and by age group. Diagnoses were classified as allergy, growth, gastrointestinal, respiratory, general body supplementation, neuropsychiatric, skin, urogenital, musculoskeletal, and other systems. Results According to the comparative analysis results of before and after the COVID epidemic, there was a decreasing trend of diagnoses in relates to allergy, respiratory, urogenital, musculoskeletal system. On the other side, there was an increasing trend in gastrointestinal, general body supplementation, growth, neuropsychiatric, skin and other system. Changes in diagnosis based on gender and age group will be described below. Conclusions This study analyzed the characteristics of diseases of Korean pediatric outpatients before and after the COVID-19 epidemic, and suggested the direction of future Korean medicine treatment and researches for pediatrics. Also, this study aimed to propose proper treatments for children by showing the role of Korean pediatric medicine related to growth and development of children during the epidemic. However, this study has limitations such as failure to track the long-term impact of COVID-19. Thus, long term follow-up studies are needed to show the effect of COVID-19 on Korean pediatric medicine.
