Since the government is fully aware of the specificity and importance of the healthcare field, it operates bureaucracy and affiliated organizations composed of many government ministries and experts and is also handling the related bureaus. However, recent incidents of humidifier disinfectant not only make these government activities unreliable but also cause disappointment to many people. Why did not the government take active measures to ensure product safety? But why was the Korea Centers for Disease Control and Prevention (KCDC) able to speed up the identification of the cause and the recovery of the product? The purpose of this study is to clarify the behavioral mechanisms of government intervention by comparing the behaviors of the Ministry of Trade, Industry and Energy and the KCDC. Then, we will discuss the desirable government structure.

This paper presents the design, implementation, and evaluation of the RFID Guardian, the first-ever unified platform for RFID security and privacy administration. The RFID Guardian resembles an "RFID firewall", enabling individuals to monitor and control access to their RFID tags by combining a standard-issue RFID reader with unique RFID tag emulation capabilities. Our system provides a platform for coordinated usage of RFID security mechanisms, offering fine-grained control over RFID-based auditing, key management, access control, and authentication capabilities. We have prototyped the RFID Guardian using off-the-shelf components, and our experience has shown that active mobile devices are a valuable tool for managing the security of RFID tags in a variety of applications, including protecting low-cost tags that are unable to regulate their own usage.

Useful data being distributed over several systems, we have a problem in accessing and utilizing them. Recognizing this problem, researchers have proposed two concepts as solutions to the problem, multidatabase and data warehouse. The one provides a virtual view over the distributed data, and the latter is a materialized view of it. Recently, more attention has been paid to the latter, which is a single of distributed database, collected along a time dimension. So, the major issues in building a data warehouse are 1) how to define a global schema for the data warehouse, 2) how to capture changes from local databases, and 3) how to represent time-varying values of data item. This paper presents an integrated approach to these issues, borrowing the research results from such areas as multidatabase, active databases and temporal databases.

Intestinal Behçet's disease is a rare, immune-mediated chronic intestinal inflammatory disease; therefore, clinical trials to optimize the management and treatment of patients are scarce. Moreover, intestinal Behçet's disease is difficult to treat and often requires surgery because of the failure of conventional medical treatment. Administration of anti-tumor necrosis factor-${\alpha}$, a potential therapeutic strategy, is currently under active clinical investigation, and evidence of its effectiveness for both intestinal Behçet's disease and inflammatory bowel diseases has been accumulating. Here, we review updated data on current experiences and outcomes after the administration of anti-tumor necrosis factor-${\alpha}$ for the treatment of intestinal Behçet's disease. In addition to infliximab and adalimumab, which are the most commonly used agents, we describe agents such as golimumab, etanercept, and certolizumab pegol, which have recently been shown to be effective in refractory intestinal Behçet's disease. This review also discusses safety issues associated with anti-tumor necrosis factor-${\alpha}$, including vulnerability to infections and malignancy.

Effect of ginseng polysaccharide fraction was examined for $CCl_4$-induced hepatotoxicity in vitro and in vivo. In $CCl_4$-injured primary cultured rat hepatocytes, treatment of the polysaccharide fraction (0.1, 0.3, 1.0 mg/ml) significantly Inhibited the release of LDH and GOT into the culture medium in a dose-dependent manner. Oral administration of the polysaccharide fraction (100, 200 mg/kg) inhibited the decrease of body weight and the increase of the ratio of liver to body weight in $CCl_4$-intoxicated rats. Elevation of GOT, GPT and ALP activity in the serum by $CCl_4$-induced hepatotoxicity was suppressed by administration of ginseng polysaccharide fraction. MDA levels increased in the serum as well as in the liver tissue by treatment with $CCl_4$ showed a tendency to be 연w in the rats given to the polysaccharide fraction. These results suggest that the polysaccharide fraction may be active substance responsible for antihepatotoxic effect of Panax ginseng.

To secure the safety of drugs without compromising drug efficacy, it can not be more important to administer the exact intended amount of active ingredients to patients. Even if the correct amount of drugs are taken in the correct manner, drug can be overdosed or less-dosed without intention unless the content uniformity of the unit dose were secured. Especially, it can be a serious problem when it comes to drugs with narrow therapeutic windows or a strong pharmacological activity at a small dose. (omitted)

With the advancement of information technology, the application of augmented reality (AR) in dentistry is an emerging research field of image-guided surgery and dental education. In addition, the digital approach to incorporating AR in dental practice management is considered to be feasible. A prototype is developed to apply AR to dental daily clinical practice in order to help dentists to access electronic dental records. This prototype delivers patients' information and related clinical data to dental clinicians directly without the need to search for the appropriate patients. Wearable AR devices are considered to be a convenient tool for practicing dentists because dental practitioners are not always able to use a computer during active clinical sessions, such as implant placement, root canal treatment, and patient-doctor communication. The use of AR to visualize passive transferred patient data would be valuable for practicing dentists.

The WeChat mini program is an application embedded in WeChat that users can use without downloading and installing. After it was officially released in 2017, many travel enterprises have launched their own mini programs on the WeChat platform. This study applies affordance theory to investigate the WeChat mini program's role in tourism activities through social network analysis using the R programming language. The authors searched the topic of "how do you perceive the travel-related WeChat mini program" and then crawled the 200 comments found; 180 comments were analyzed after data cleansing. The results show that travel-related WeChat mini programs play a very important role in Chinese social network tourism activities. This paper found that WeChat played a more active role in various tourism-related interactions with Chinese social networks. Moreover, the results show how affordance theory is applied to the use of WeChat mini programs.

국가의 임의적인 침해로부터 국민의 재산권과 자유권을 보호하려는 소극적인 법치국가의 역할은 오늘날 의회민주주의 시대에는 더 이상 의미를 찾을 수 없게 되었다. 왜냐하면 오늘날 개인에게 기회와 사회보장적 급부를 제공하는 국가의 역할은 자유로운 삶을 유지하는데 있어서 기본권을 침해하지 않아야 하는 것 못지않게 중요하게 되었기 때문이다. 기본권을 침해하지 않는 소극적 국가에서 기본권을 보호할 뿐만 아니라 실현하는 적극적 국가로 현대국가의 역할이 변한 것이다. 그러므로 현대 의회민주주의에서 고전적인 법치국가 기능의 발전적 변화는 국민의 기본권 보호와 실현을 위해서 의회의 더 책임 있는 입법 활동을 요구한다. 따라서 현대국가에서 기본권 중의 하나로 인식되는 사회적 기본권의 구현에 있어서도 의회의 적극적인 입법 활동이 요청된다. 그러나 행정부에 입법권을 과도하게 위임하는 한국 국회는 사회적 기본권의 구현에 있어서 현대 의회민주주의가 요구하는 기준을 충족시키지 못하고 있다.

In this paper, we propose a method for automatically analyzing the bone formation in a mouse model of frontal bone defect. We perforate two holes of 0.8mm diameter in the frontal bone and observe the bone formation process using a micro CT. Because the conventional analysis software of the micro CT does not support automatic analysis of the bone formation status, we have to use a manual analysis method. However the manual analysis is very cumbersome and requires a lot of time, we propose an automatic analysis method. It rotates the image around three axes directions so that the mouse's skull come into regular position. It calculates the cumulative image of the voxel values for the perforated bone surface. It estimates the hole location by finding the darkest point in the cumulative image. The proposed method was applied to 24 CT images of saline administration group and PTH administration group and hole location was estimated. BV/TV index was calculated for the estimated hole to evaluate the bone formation status. Experimental results showed that bone formation process is more active in PTH administration group. The method proposed in this paper could replace successfully the cumbersome and time consuming manual job.
