This paper empirically examines the relationship between outward foreign direct investment (OFDI) of Korean manufacturing firms and the servicification of domestic employment using a firm-level panel data. In this study, considering the issue of low productivity in the Korean service sector, we categorize service employment into core and non-core services and investigate their relationship with OFDI using the firm-fixed effects model. The empirical results show that the share of core service employment exhibits a positive correlation with the extensive OFDI. On the other hand, the share of non-core service employment, which is expected to generate relatively low value-added, does not show a significant relationship with the extensive OFDI. When we divide the samples based on host countries and the type of subsidiaries, the impact on servicification varies depending on the technological capabilities of host countries and their participation in global value chains. Our study suggests that Korean manufacturing firm's internationalization strategies may facilitate a transition from labor-intensive employment, like the cases in advanced countries, to technology-intensive employment through OFDI and other means.

Global e-commerce websites offer personalized recommendation services to gain sustainable competitiveness. Existing studies have offered personalized recommendation services using quantitative preferences such as ratings. However, offering personalized recommendation services using only quantitative data has raised the problem of decreasing recommendation performance. For example, a user gave a five-star rating but wrote a review that the user was unsatisfied with hotel service and cleanliness. In such cases, has problems where quantitative and qualitative preferences are inconsistent. Recently, a growing number of studies have considered review data simultaneously to improve the limitations of existing personalized recommendation service studies. Therefore, in this study, we identify review and rating mismatches and build a new user profile to offer personalized recommendation services. To this end, we use deep learning algorithms such as CNN, LSTM, CNN + LSTM, which have been widely used in sentiment analysis studies. And extract sentiment features from reviews and compare with quantitative preferences. To evaluate the performance of the proposed methodology in this study, we collect user preference information using real-world hotel data from the world's largest travel platform TripAdvisor. Experiments show that the proposed methodology in this study outperforms the existing other methodologies, using only existing quantitative preferences.

We examine evidence on the relationship between firms that targeted by the Financial Supervisory Service for allegedly manipulating annual earnings and accounting quality measured by the discretionary accruals, an issue with important public policy implications. The main purpose of this paper is to empirically investigate the extent to which Korean WDS(Window Dressing Settlement) firms identified by the financial supervisory service in their audit review exhibit higher level of accounting quality in order to avoid any potential negative effects and to regain public confidence after audit review. In this study, we analyzed 51 WDS firms and 102 control firms which traded in the Korean Stock Exchange market during the period from 2000 to the 2010. The number of observations subject to various tests are 251 and 502 firm-years for WDS and control samples respectively across the 5 year sample period. The results of the study show that the accounting quality after auditor review be significantly improved. This result suggests that the FSS's audit review system would control the accounting quality and then improve the transparency of the accounting information. Thus it may be suggested that the current audit review system is efficient ways to lead listed firms to provide transparent financial statements.

Background : Previous studies have reported that enhanced continuity of care prevented a sudden worsening in progress among chronic disease patients, and as a result was favorable for efficient spending of health care funds. This study aims to estimate the continuity of care of Korean with diabetes and to identify factors affecting the continuity of care. Methods : This study used the Korean National Health Insurance Claims Database which includes E11 (ICD-10) as a primary or secondary disease as of 2006. Study population is 1,160,725 type 2 diabetics (20-84 years). Continuity of Care Index (COC), Modified, Modified Continuity Index (MMCI), and Most Frequent Provider Continuity (MFPC) were used as indexes of continuity of care. Results : The continuity of care in the study population was $0.94{\pm}0.10$ as calculated by MMCI, $0.91{\pm}0.16$ as calculated by MFPC and $0.86{\pm}0.23$ as calculated by COC. The lower continuity of care was shown in the patients who were female, 65 and over years old, Medical Aid recipients, 13 times or more visitors, hospital users as main attending medical institution, patients experienced hospitalizations or comorbidities. Conclusion : The continuity of care for adult patients with type 2 diabetes was high in Korea, and showed variation according to patients' characteristics. This result provides empirical evidence for policymakers to develop or strengthen programs for managing patients showing low continuity of care.

Objectives : Traditional Korean Emergency Medicine (EM) has been developing for thousands of years, however its value was not properly considered after 19th century modernization. The purpose of this study was to review the current status of EM in Korean Medicine and suggest methods for improvement. Methods : We performed systematic reviews of the definition, current medical system, and educational curriculum of EM in Western Medicine, traditional Korean and Chinese Medicine, and integrated Western and traditional Chinese medicine with the use of medical classics and text books. We also analyzed the trends in published research articles to discuss the current situation in the field of traditional Korean EM, and to provide methods for its establishment and development with traditional Korean medicine. Results : The definition of EM as a treatment of acute disease shares common understanding among traditional Korean, Chinese, and Western medicine. We presented descriptions of EM in many medical classics, however current law and EM service does not include these. As for the review of publications during the last 20 years, we found 21 articles in several fields that confirmed the need for more investigation. Conclusion : Traditional Korean EM has a long history and clinical experiences that can be found in medical classics, textbooks and research articles. There is an urgent need for more studies on traditional Korean EM as an emergency medical service system, and in terms of educational curriculum and related policies to improve Evidence-Based teaching.

Objectives : This study aims to estimate the oral antihyperglycemic medications adherence among ambulatory care with adult type 2 diabetes patients and to identify factors affecting the medication adherence in Korea. Methods : This study used the Korean National Health Insurance Database. Study population was 40,082 patients who were 20 years of age or older and first diagnosed with type 2 diabetes (ICD-10: E11) in 2004. The patients were followed up for two years in order to measure adherence with oral antihyperglycemic medications. The level of medication adherence was measured by the medication possession ratio (MPR). Results : The average MPR in the study population was 49.5%. The appropriate adherence rate (MPR$\geq$80%) was 29.4% and showed variation according to the characteristics of individual patients. Multiple logistic regression analysis revealed that the odds of appropriate adherence increased with female (OR:1.21, CI:1.14-1.27), older age, increasing ambulatory care visits, health insurance (OR:1.53, CI:1.33-1.76), decreasing ambulatory care providers, using a specialized general hospital as their main attending medical institution (OR:10.08, CI:8.96-11.33), having co-morbidity, using polytherapy (OR:1.07, CI:1.01-1.13). Conclusions : The medications adherence for patient with type 2 diabetes is low in Korea, and shows variation according to the characteristics of patients. For proper management of diabetes, health care policy is expected to be enacted to improve medications adherence continuously. In particular, more intensive management is needed for patients with low medications adherence. Also, health care policy makers need to develop the program to induce health care utilization by a patient to be more concentrated with the same provider.

Polypharmacy is increasing owing to an increase in the elderly population and multimorbidities associated with the increased risk of administration of potentially inappropriate medications (PIMs). The negative effects of polypharmacy on various health conditions and aspects, such as fall, fracture, mortality, cognitive function, and dementia, have been reported. The management of excess and inappropriate polypharmacy through proper interventions and local or national guidelines has been highlighted. The purpose of polypharmacy management is to appropriately prescribe medicines that are essential to treat diseases in patients and to avoid inappropriate polypharmacy, such as interactive or duplicate medicines under prescription and PIMs for specific diseases. Community pharmacists in Australia, the EU, USA, and Japan are collaborating with prescribers to review medications to ensure that the patients can be prescribed appropriate medications. The service cost is reimbursed by public or private insurers. A study in the United States has shown that even with medication review costs, the overall medication cost has reduced. In Korea, various projects such as Drug Utilization Review service and safe use of medicines have been conducted; however, no national guidelines or management measures have been established. It is necessary to implement a national long-term plan on polypharmacy management. Furthermore, a phased implementation plan is required. Shortly, active medication review services and education programs for healthcare professionals with the support of the government should be considered in Korea with reference to other countries in order to raise awareness of seriousness and risks of inappropriate polypharmacy.

Objectives : To compare the performance of three comorbidity measurements (Charlson comorbidity index, Elixhauser s comorbidity and comorbidity selection) with the effect of different comorbidity lookback periods when predicting in-hospital mortality for patients who underwent percutaneous coronary intervention. Methods : This was a retrospective study on patients aged 40 years and older who underwent percutaneous coronary intervention. To distinguish comorbidity from complications, the records of diagnosis were drawn from the National Health Insurance Database excluding diagnosis that admitted to the hospital. C-statistic values were used as measures for in comparing the predictability of comorbidity measures with lookback period, and a bootstrapping procedure with 1,000 replications was done to determine approximate 95% confidence interval. Results : Of the 61,815 patients included in this study, the mean age was 63.3 years (standard deviation: ${\pm}$10.2) and 64.8% of the population was male. Among them, 1,598 2.6%) had died in hospital. While the predictive ability of the Elixhauser's comorbidity and comorbidity selection was better than that of the Charlson comorbidity index, there was no significant difference among the three comorbidity measurements. Although the prevalence of comorbidity increased in 3 years of lookback periods, there was no significant improvement compared to 1 year of a lookback period. Conclusions : In a health outcome study for patients who underwent percutaneous coronary intervention using National Health Insurance Database, the Charlson comorbidity index was easy to apply without significant difference in predictability compared to the other methods. The one year of observation period was adequate to adjust the comorbidity. Further work to select adequate comorbidity measurements and lookback periods on other diseases and procedures are needed.

Background: The appropriate management of diabetes mellitus(DM) can help reduce its relapse and economic burden, but the level of management of DM in Korea is reported to be insufficient. This study aims to identify the management level of DM by figuring out the HbA1c examination performance rate of the diabetics and analyzing the variation according to the characteristic of a diabetic. Methods: This study used the Korean National Health Insurance Database which includes E10-14(ICD-10 code) as a primary or secondary disease as of 2006. Study population is 1,892,062 diabetics excluding 393,784 patients with the first attack of DM in 2006, 33,440 diabetics who died in 2006, and 21,299 patients with DM having no record of ambulatory care among the 2,340,585 DM patients in total. Results: The HbA1c examination performance rate of all DM patients in our country is estimated to be 41.5% as of 2006 and shows variation according to the characteristic of individual DM patients. The highest performance odds was shown by the patients who were below 19 of age, insured for health insurance, attended more than 3 ambulatory care providers, made ambulatory care visits more than 10 times annually, attended a specialized general hospital as their main attending medical institution, had a record of hospitalization or had co-morbidity. Conclusion: This study propose that is necessary to make politic preparations for the appropriate management of diabetes at a national level, and particularly, the patients with advanced age, the ones dependent on Medical Aid, and the ones using hospitals or clinics, whose appropriate management seems vulnerable, demand a careful management.
