To enhance the performance of privatized firms and state-owned enterprises, Vietnamese government set up a specialized monitoring body named State Capital Investment Corporation (SCIC) in 2006 to supervise their performance. This motivated us to conduct this study to investigate the effective control of SCIC on privatized firms' performance. We collected the annual reports of 500 non-financial privatized firms listed on HSX and HNX during the period from 2007 to 2017 from Thomson Reuters. Observations with missing values were removed and trimming outliers were implemented resulting in a dataset comprising of 4146 firm-year observations. We applied a quadratic regression model of state ownership on firms' performance, and applied the method of Baron and Kenny (1986) to test the moderating effect of SCIC control. To fix "selection bias" that may occur and result in endogeneity of moderator (M), we utilized the PSM technique to analyze the marginal effect of the moderator (SCIC) on privatized firms' performance. Our findings indicate a positive moderating role of SCIC on the relationship between the state ownership and firms' performance. This implies that there is a positive effect of liberating the management of the private firms from government control, which also means that lesser the intervention of government in the day to day operational activities of a private firm, better the performance of a privatized firm is.

Purpose: The purpose of this study was to evaluate risk factors of pressure injuries in patients after neurosurgery. Methods: A retrospective case-control study was conducted using 273 patients undergoing neurosurgery admitted to a general hospital from 2015 to 2021. Data were collected from September 1 to 30, 2021. The data were analyzed using the SPSS/WIN 26.0 program. Results: Risk factors significantly influencing the occurrence of pressure injuries in the patients undergoing neurosurgery were hypertension (OR=3.12, p=.024), postoperative hypoalbuminemia (OR=0.30, p=.028), and prolonged operative duration (OR=1.00, p=.001). The regression model explained 86.0% of the variance of the outcome variable. Conclusion: In order to prevent surgery-related pressure injuries in patients undergoing neurosurgery, thorough blood pressure management, avoidance of hypoalbuminemia, and preventive nursing intervention considering operative duration are required.

Illegal waste dumping is one of the major problems that the government agency monitoring water quality has to face. One solution to this problem is to find an efficient way of managing and supervising the water quality under various kinds of conditions. In this article we establish WQMA (water quality monitoring algorithm) based on the time series intervention model. It turns out thatWQMA is quite successful in detecting illegal waste dumping.

In September 2010, the Korea government increased the speed limit on the Gyeongbu Expressway (Cheonan IC.-Yangjae IC) from 100 to 110 km per hour. This paper considers ARIMA-Intervention model to analyze the effects of the speed limit change on the incidences of traffic accidents and injuries. In addition, in order to investigate the effects more clearly, we also analyze the difference between the two lines of Cheonan IC-Yangjae IC and Busan IC-Cheonan IC. As a result, we observe that the numbers of accidents and injuries have increased after the speed limit change. The increases are strikingly distinctive in comparison to other lines (Busan IC-Cheonan IC) where there have been no changes in the maximum speed limit.

Background: Effective policy implementation is essential for a healthy workplace. The Ryan-Kossek 2008 model for work-life policy adoption suggests that supervisors as gatekeepers between employer and employee need to know how to support and communicate benefit regulations. This article describes a workplace intervention on a national employee benefit, Family and Medical Leave Act (FMLA), and evaluates the effectiveness of the intervention on supervisor knowledge, awareness, and experience with FMLA. Methods: The intervention consisted of computer-based training (CBT) and a survey measuring awareness and experience with FMLA. The training was administered to 793 county government supervisors in the state of Oregon, USA. Results: More than 35% of supervisors reported no previous training on FMLA and the training pre-test revealed a lack of knowledge regarding benefit coverage and employer responsibilities. The CBT achieved: (1) a significant learning effect and large effect size of d = 2.0, (2) a positive reaction to the training and its design, and (3) evidence of increased knowledge and awareness regarding FMLA. Conclusion: CBT is an effective strategy to increase supervisors' knowledge and awareness to support policy implementation. The lack of supervisor training and knowledge of an important but complex employee benefit exposes a serious impediment to effective policy implementation and may lead to negative outcomes for the organization and the employee, supporting the Ryan-Kossek model. The results further demonstrate that long-time employees need supplementary training on complex workplace policies such as FMLA.

Purpose: This study was aimed to develop the multicomponent intervention for preventing delirium among postoperative patients in a surgical intensive care unit (SICU). Methods: Using a quasi-experimental pre & post-test design with a non-equivalent control group, a total of 88 hospitalized patients in a SICU participated in this study. The 44 patients were allocated in each experimental and control group. The experimental group received the multicomponent intervention for delirium prevention including a delirium assessment and nursing intervention using a checklist, whereas the control group was provided with a standard care. The primary outcome of this study was the delirium incidence during the course of hospitalization. Results: There were no significant differences in the demographic and clinical characteristics between the two groups. The delirium occurred in 19.2% in the experimental group, whereas 38.6% in the control group ($x^2=4.526$, p<.05). Conclusion: The findings of the study demonstrated an effect of the multicomponent delirium prevention intervention in decreasing the delirium incidence rate over the standard care among the patients in SICU.

The architectural influence from the Yuan had impact on the Goryeo Dynasty in earnest during Yuan intervention period in the 14th century. The representative examples which were influenced by the Yuan architecture are the Eungjinjeon in Seongbulsa(成佛寺) temple, the ten-story stone pagoda of Gyeoncheonsa(敬天寺) temple site, the Bogwangjeon in Simwonsa(心源寺) temple, the Hoeamsa(檜巖寺) temple and so on. Notwithstanding the changes of relationship between two countries, it can be comprehended that there was a selective acceptance of the Yuan architectural peculiarities in Goryeo Dynasty. It means that the adoption of foreign culture in Korea has not been inevitable from the unilateral demand, but been autonomous by perceiving as the advanced culture. This tendency was maintained even though the government had been changed.

The purpose of this study is to explore adolescent depression, increase understanding of social problems, and develop prevention and intervention strategies. As a research method, social big data was used to collect information related to 'youth depression', and related factors were identified through data mining and analysis of related rules. We used 'Sometrend Biz Tool' to collect and clean data from the web and then analyzed data in various languages. The study found that online articles about depression decreased during the school holidays (January to March), then increased from March to the end of June, and then decreased again from July. Therefore, it is important to establish a government-wide depression management monitoring system that can detect risk signs of adolescent depression in real time. In addition, regular stress relief and mental health education are needed during the semester, and measures must be prepared to deal with at-risk youth who share their depressed feelings in cyberspace. Results from these studies can be expected to provide important information in investigating and preventing youth depression and to contribute to policy development and intervention.

During the last year, we had a very severe situation with the strike of physicians working in medical facilities. From that time, many politicians and scholars insisted on the expansion of public hospitals to enhance the public role in the medical care sector. They think that private medical facilities work for profit motivation and that the high proportion of private to whole facilities is an obstacle to the public function of medical care under social insurance system. They found that one of the reasons for failing to prevent the physicians' strike was the high proportion of private facilities. Others insisted that the strike was not a good reason for the expansion of public hospitals. The physicians' strike was a very rare case, and it is not a good basis for generalization of the discussion of public hospitals. Last year almost all apprentice physicians in public facilities took part in the strike, and consequently the public hospitals also lost the role of public function. They view this increasing involvement of government in the medical sector as improper and the cause of inefficiencies. In this paper we review the debate over the expansion of public facilities. To clarify the debate, we review traditional criteria for the role of government in a market system and to apply these criteria to medical care. There are two traditional areas where government Is acknowledged to have a role in a market system: market imperfections and market failure. Where market imperfections and market failure exist, there may be a role for government. The justifications for government intervention are consumer protection and the existence of externalities. One of externalities is to provide medical care for the poor. The appropriate measures to provide medical owe to the poor can be sought in both demand and supply side subsidies. National health insurance is a method of demand subsidies and establishment of public hospitals is a method of supply side subsidies. Under the National Health Insurance System, the expansion of public hospitals is not an appropriate subsidy policy.

This paper analyzed four different perspectives on health care reform in Korea in terms of the basic values, formulated problems and reform plans, implementation methods, and supporting groups. The medical security plan was insisted by social security specialists and social activists focusing on the integration of medical insurance coops in order to enhancing equity and right of the people. However, its perspective was limited to promoting security instead of reforming health care system. The government proposed the health care reform plans in 1994 and in 1997, focusing on promoting efficiency by remedying many problems in health care delivery system. However, its implementation was not successful due to the lack of organizational and financial supporters. Recently, two opposite proposals were issued. The market reform plan paid attention to revitalizing the market function to promoting efficiency by allowing hospitals to treat private patients instead of applying the medical insurance regulation. The government reform plan focused on intensifying governmental planning and intervention in the health care sector in order to removing inefficiency and promoting equity with the supports of social activists and labor unions. Finally, this paper proposed an alternative plan to promote harmonious social relationship between actors in the health care system.
