A study on the status of sickness and medical care of insured and non-insured groups of employee and his family in Naju fertilizer company, in the year of 1973, was carried out. The results obtained are as follows: 1. 66.8% of all employee was subscribed in this medical insurance program. No woman employee was subscribed and the rate of subscription was increased from 16.1% to 92.0% by age increases. 2. Also, as of period of service, the rate of subscription was increased from 11.3% to 89.4% by the period gets longer. 3. Employee who reside within boundary of the company (76.2%) subscribed more than that whom reside outside boundary (63.9%). 4. Rate of subscription was also indreased by family size becomes larger. In case of single, it was only 19.6% but in the case of family size became more than 6, it increased to 87.4%, 5. As of amount of monthly income, although no one had subscribed those who get less than 30,000 won a month. Subscriber, increased by monthly income get greater. 6. Subscribed family reside within company boundary utilized hospital 35.5 times a year whereas non-subscribed family reside within these utilized 12.5 times. And, subscribed family reside outside boundary utilized hospital 32.2 times a year and non-subscribed family utilized 9.6 times. Regardless of resident area, family who subscribed to this program utilized hospital more often than non-subscribed family. 7. The utilization of the hospital became gradually frequent from 15.6 times to 36.5 times per family by family size became larger. but in non-subscribed group, although it was increased from 8.3 times to 16.5 times per family, it was droped to the least 6.9 times at 2 person family. 8. 17,496 hospital visits were made by all employee and his family in the year 1973. 86.9% of them was made by subscribed group and the rest (13.1%) was made by non-subscribed group. Observing of the type of these sickness by the classification of WHO, only three types of VII (26.7%), XVII (25.0%) and IX(19.3%) were made more often by non-subscribed group while the others were made more by subscribed group. 9. Anual average medical expenditure per family was 13,098.9 won for subscribed family while it was 3,076.1 won for non-subscribed family. 10. Anual average hospital visits per capita was 6.5 times for subscribed groups and 3.4 times for non-subscribed group. Anual average medical expenditure per capita was 2,580.8 won for subscribed group while it was 1,061.0 won for non-subscribed one.

The relationship between past liver disease history and the risk of primary liver cancer was analyzed in a hospital-based case-control study conducted in Seoul on 165 patients with histologically or serologically confirmed hepatocellular carcinoma and individually age- and sex-matched 165 controls in hospital for ophthalmologic, otologic, or nasopharyngeal problems. Significant association were observed for liver deseases occurring 5 or more years before liver cancer diagnosis [OR,4.9;95% confidence interval (CI), $1.6{\sim}14.0$) and family history of liver disease(OR, 9.0;95% CI, $2.1{\sim}38.8$). These associations were not appreciably modified by allowance for major identified potential confounding factors. From these results, it is possible to speculate that liver cell injuries caused by various factors might be a common pathway to developing primary liver carcinoma. Considering the significant effect of family history of liver diseases on PLCA risk after adjusting past liver disease history, there might be genetic susceptibility in the carcinogenic mechanism of liver cancer. Further investigations are needed to clarify the effect of family history of liver disease on PLCA risk.

Healthcare and data science are often linked through finances as the industry attempts to reduce its expenses with the help of large amounts of data. Data science and medicine are rapidly developing, and it is important that they advance together. Data science is a driving force in transition of healthcare systems from treatment-oriented to preventive care in healthcare 3.0 era. It enables customized precision-based medicine that current healthcare systems cannot facilitate, and discovers more cost-effective treatment. Currently, healthcare big data is in the reality of medical institution, public health, medical academia, pharmaceutical sector as well as insurance agency. With this motivation, the medical college of Soonchunhyang university has performed a 'healthcare data science initiative(HDSI)' since 2014. Most of domestic HDSI programs focus on short-term contents such as mentoring and sharing cases for data science. Therefore, it is difficult to provide education tailored to the level of skills and job competency required at the practical site. Soonchunhyang HDSI implemented specialized strategies for improving resilience and response to changes in the IT education of current healthcare with the emphasis on the need for systematic activation of the practical HDSI. The HDSI has been performed as a part of on industry-academic link program in CK-1. Through quantitative and qualitative analysis, this paper discussed the HDSI process, performance, achievement, and implications.

It was not until 1975 that cancer registration was initiated in Korea; voluntary registration of cancer patients of training hospitals throughout the country began under the auspices of the Korean Cancer Society(KCS). However, an official cancer registration, the Korea Central Cancer Registry(KCCR), began on July 1st, 1980. Forty-five training and two non-training hospitals throughout the country initiated registration of patients in whom neoplasms had been found. Data related to case information specified are to be sent to the KCCR at the National Medical Center(it moved at National Cancer Center in 2000). The initial cancer registration of KCS was merged to the KCCR in 1980. Although the KCCR covers most all the large training hospitals in Korea, it cannot provide incidence data. It is, however, the only of its kind in the world, being neither hospital nor population based. The first population based cancer registry(PBCR) was launched in a small county, Kangwha(it has around 80,000 inhabitants), by Yonsei University Medical College in 1983. All data were collected by active methods, and incidence statistics for 1986-1992 appeared in Vol VII of the CI5. Another PBCR, Seoul Cancer Registry(SCR), started in 1991. It was supported by a civilian foundation, the Korean Foundation for Cancer Research. The basic idea of case registration of SCR was the incorporation of KCCR data to PBCR, e. g. dual sources of case registration, i.e., from the KCCR and also including cases diagnosed in small hospitals and other medical facilities. Assessing completeness and validity of case registration of SCR, the program and methodology used by the SCR was later extended to other large cities and areas in Korea, and the PBCR in each area was established. Cancer incidence statistics of Seoul for 1993-1997, Busan for 1996-1997, and Daegu for 1997-1998, as well as Kangwha for 1993-1997, appeared eventually in Vol VIII of the CI5. The Korean or 'pillar' model for a PBCR is a new one. The KCCR data file is a reliable basis, as a pillar, for a PBCR in each area. The main framework of the model for such a registry is the incorporation of a KCCR data file with data from additionally surveyed cases; the data related to cancer deaths, medical insurance claims, and visit-and surveillance of non-KCCR medical facilities. Cancer registration has been adopted as a national cancer control program by Korean government in 2004 as the Anti-Cancer Act was enacted. Since then, some officers have tried to launch a nation-wide PBCR covering whole country. In the meantime, however, cancer registration was interrupted and discontinued for years due to the Privacy Protection Law, which was solved by an amendment of the Anti-Cancer Act in 2006. It would be premature to establish the nation-wide PBCR in Korea. Instead, continuous efforts to improve the completeness of registration of the KCCR, to progress existing PBCRs, and to expand PBCRs over other areas are still to be devoted. The nation-wide PBCR in Korea will be established eventually with summation of the PBCRs of the Korean model.

This study was investigated the subjects' satisfaction in the therapy among the internet age. The subjects of the study were 200 women who have menses in ages from 18 to 55 among visitors of five public health centers and attendants of A church in Gwangju. The period of the study ranged from September 6 to October 10, 2010. As a study instrument, this study used a questionnaire developed based on questions from studies published by An Seung-duk(2003). This study used SPSS 17.0, for a frequency analysis, a cross-tabulation and a chi-squared test. During the analysis, 43.4% of the subjects used the complementary alternative therapy. 56.3% visited used oriental medical clinics or herbal medicine shops as places to use the therapy, 42.5% received medicine, acupuncture, moxibustion and cupping at oriental medical clinics. As expenses of the therapy, 56.3% spent less than 500,000 won a year. After the therapy, 51% answered they were satisfied with the therapy. In conclusion, it was discovered that use rate of the therapy is increasing, the subjects decided to use the therapy for themselves or through recommendation from acquaintances, and they mainly depended on reliable oriental medical clinics or folk remedies against menstrual pain, and insurance benefits for the therapy should be considered except oriental medical hospitals or clinics.

Objectives : The incidence of colorectal cancer increased greatly among the elderly in Korea, but the relationship between smoking and colon cancer remains controversial. Few studies have targeted Asian elderly people. We analyzed the smoking status, the amount smoked, and the smoking duration as risk factors of colorectal cancer to determine their association and causality. Methods: The cohort members (n=14, 103) consisted of 4,694 males and 9,409 females, and they were derived from the Korea Elderly Phamacepidemilogic Cohort (KEPEC), which was a population-based dynamic cohort. They were aged 65 years or more and they lived in Busan Metropolitan City between from 1993-1998; they were beneficiaries of the Korean Medical Insurance Corporation (KMIC). The baseline information was surveyed by a self-administered mailed questionnaire; after 8.7 person-years of mean follow up period, 100 cases of colorectal cancer occurred. The adjusted relative ratio (aRR) of smoking status, the smoking amount and the smoking duration were calculated from the Cox's proportional hazard model with the never-smokers as a reference group and the Cox model controlled for age, gender, precancerous lesions of CRC, medication history of NSAIDs & antibiotics, the alcohol drinking status and BMI. Results : Compared with the never smokers, the aRRs were 2.03 (95% CI=1.02-4.03) and 1.36 (95% CI=0.80-2.32) for the ex-smokers and current smokers, respectively. Statistical significant trends were not observed for the dose-relationship among the elderly, either for the mean daily amount smoked (p for trend=0.28) or for the total amount (p for trend=0.15). Still, the aRRs were 1.51 (95% CI=0.97-2.34) for the elderly who smoked less than 40 years and 2.35 (95% CI=1.16-4.74) for the elderly who had 40 years or more of smoking (p for trend=0.06). Smokers who started smoking before the age 20 had an increased aRR of 2.15 (95% CI=1.17-3.93) compared to the never smokers. Conclusions : After controlling for age, gender, precancerous lesion of CRC, medication history of NSAIDs & antibiotics, the alcohol drinking status and BMI, smoking increases the risk of colorectal cancer among elderly people. The age when starting smoking is also important.

The purpose of this study is to analyze the use of hospital, hospitalization, medical service, discharge and power of medical care patients who are concerned about moral hazard. We conducted focus group interview with 3 medical care patients and their families and 5 workers who had worked for more than 4 years in a nursing hospital. The main results and implications are as follows. First, admission to nursing hospitals was mostly based on the linkage between the medical institutions and the competition to attract the patients rather than the choice of the patients. Second, the main cause of the long-term hospitalization of medical assistance patients was the lack of social protection measures such as absences of residence and care giver, although there are factors that cause moral hazard such as low self-pay. Third, most of the patients were in need of treatment, but they were admitted to the hospital even though their needs were not higher than those of the health insurance patients. Fourth, the rehabilitation service is the mainstay of the medical service of the nursing hospital, and the roles of nursing staff and care givers are important. Fifth, medical care patients are paying medical expenses for nursing hospitals due to cost of living and family support, but they are exempted from the hospital expenses or the burden of their own expenses in the hospital. Sixth, public institutions and social welfare institutions have not managed continuously since commissioning patients to nursing hospitals and have neglected the connection with community services after discharge.

Objectives The purpose of this study is to improve the accessibility of Korean medicine by standardizing managements, improving quality of medical services, and reducing medical costs in ankle sprain by develop clinical pathway (CP). Methods The development of CP in this study is based on clinical practice guideline (CPG) for ankle sprain, and aims to maximize the quality of treatment, such as reducing treatment time and medical costs, and increasing patient satisfaction through standardized pathway. The CP was revised after consultation and review by the advisory committee. The advisory committee is consisted of a stakeholder group applying the CP. Results In previous research studies, there were no Korean medicine CP studies on ankle sprain. Based on CPG for ankle sprain and analysis of medical records, 6 types of time task matrix type CP (for Korean medicine doctors, medical assistant, patients) and 4 types of algorithm type CP (for Korean medicine clinics, Korean medicine hospitals, and cooperative practicing hospitals, public medical centers) were derived as a result. Conclusions Ankle sprain CP is expected to not only increase patient satisfaction and maximize the quality of treatment, but also reduce the financial burden of health insurance by reducing medical costs.

The purpose of this study is to find a way to improve the hospice system to increase comfortable home death, which people prefer, by understanding the factors affecting the difference in the rate of home death between South Korea and America within the hospice system. This study employs the Most Similar Systems Design, which is a case study approach. The result of this study is that both countries have public health insurance systems that are identical in terms of the appropriate time for the receipt of hospice services and the application procedure, which requires that two doctors confirm the patient's hospice eligibility. The main difference is that in South Korea, inpatient hospice is prevalent, whereas routine home care is predominant in the United States. Furthermore, in the United States, hospice assistants and housekeepers support at-home daily living care. Additionally, the United States provides inpatient respite care to allow care-giver, such as family to rest and there is no restriction on hospice-eligible diseases. To increase the accessibility of voluntary home death in South Korea, it is necessary to activate and expand the home type hospice service range and provide at-home daily living care, care-giver support services. Furthermore, there should be no restrictions on hospice-eligible diseases.
