Recently, attempts have been made to convert unstructured text into vectors and to analyze vast amounts of natural language for various purposes. In particular, the demand for analyzing texts in specialized domains is rapidly increasing. Therefore, studies are being conducted to analyze specialized and general-purpose documents simultaneously. To analyze specific terms with general terms, it is necessary to align the embedding space of the specific terms with the embedding space of the general terms. So far, attempts have been made to align the embedding of specific terms into the embedding space of general terms through a transformation matrix or mapping function. However, the linear transformation based on the transformation matrix showed a limitation in that it only works well in a local range. To overcome this limitation, various types of nonlinear vector alignment methods have been recently proposed. We propose a vector alignment model that matches the embedding space of specific terms to the embedding space of general terms through end-to-end learning that simultaneously learns the autoencoder and regression model. As a result of experiments with R&D documents in the "Healthcare" field, we confirmed the proposed methodology showed superior performance in terms of accuracy compared to the traditional model.

Objective : This study aimed to determine the impact of an instrumental daily living activity program for adults with developmental disabilities on their daily living activities and quality of life (QOL). Methods : This study used a single-group pre-test-post-test experimental design. Participants comprised 17 adults with developmental disabilities from the Welfare Center for the Disabled. This program consisted of 10 sessions, including pre- and post-assessments, pertaining to training and education on grocery shopping, meal preparation and cleaning, home management, safety, and emergency management. The evaluation tools used in this study were the Quality of Life Questionnaire, Korean version of the Life Space Assessment (K-LSA), and Korean version of the Instrumental Activities of Daily Living (K-IADL). Results : There was a statistically significant difference in the QOL and K-IADL scores before and after the instrumental activities of daily living occupational therapy program, and there was no statistically significant difference in the K-LSA scores. Conclusion : This study confirmed that implementing an IADL program for adults with developmental disabilities had a positive impact on performance and QOL. For adults with developmental disabilities to participate in daily life and society, interventions for work participation, including training in activities of daily living, must be expanded.

PURPOSE: This study aimed to investigate the effect of a progressive balance training program with whole-body vibration stimulation on knee joint pain, dysfunction, psychosocial status, and balance ability in individuals aged ≥ 65 years with knee osteoarthritis. METHODS: A total of 40 individuals aged ≥ 65 years with osteoarthritis of the knees participated in the study. Using a randomization program, participants were assigned to an experimental group (n = 20) or a control group (n = 20). Both groups were assigned a knee strength training program, and a progressive balance training program with whole-body vibration stimulation was assigned to the experimental group. All interventions were conducted three times a week for four weeks. Participants were evaluated for the following: pain (numeric rating scale, NRS), knee dysfunction (Korean version of the Western Ontario and McMaster Universities Arthritis Index, K-WOMAC), fall efficacy (Korean Version Falls Efficacy Scale, K-FES), quality of life (Euro Quality of life 5 Dimension, EQ-5D), and advanced balance scale score (Fullerton advanced balance scale, FAB) before and after the intervention, and the effects of the intervention were compared accordingly between groups. RESULTS: Both groups showed significant differences in the results of the NRS, K-WOMAC, K-FES, and EQ-5D assessments before and after the intervention, and there was a significant difference in the amount of change between the two groups (p < .05). There was a significant improvement in FAB in all but items FAB 8 and FAB 9 after the intervention in the experimental group. In the control group, there was a significant improvement in FAB 1, FAB 2, FAB 7, and FAB total after the intervention (p < .05). In addition, there was a significant difference in the amount of change between the two groups in all items except FAB 8 and FAB 9 (p < .05). CONCLUSION: The progressive balance training program with whole body vibration stimulation is an effective intervention method with clinical significance in improving knee joint pain, knee disability index, psychosocial level, and balance ability in adults aged ≥ 65 with osteoarthritis of the knees.

The first priority of sedation for incorporative children in pediatric dentistry is a safety. Therefore, evidence-based practices in health care are needed for preventing medical accidents. In accordance with the rise of the evidence based medicine, the interest in Evidence-Based Dentistry is increasing in the field of dentistry. However, systematic research about Evidence-Based sedation in Korea has rarely been done. As such, the purpose of this systematic review is to critically analyze the available scientific literature regarding dental sedation and to seek the next developmental strategies about evidence based pediatric dental sedation. A broad search of the 5 databases of the systematic reviews manual of the National Evidence-based Healthcare Collaborating Agency in Korea were referenced: 1) Core search database- KMbase, KISS; 2) Academic information and portal; 3) the National Assembly Library; 4) DBpia, and 5) RISS. Of a total 470 themes limited to the search term of "dental sedation", in accordance with the PRISMA statement for reporting systematic reviews of health sciences interventions, a literature selection process, which includes the removal of overlapping down the flow chart, was performed. Of the remaining 31 articles, two authors read through articles independently and added or removed articles using the exclusion criteria. Finally, twenty published papers of acceptable quality were identified and reviewed. This systemic review of Korean pediatric dental sedation practices for the last twenty-five years was based on the objective criteria defined in the GRADE process and identified consistent evidence. The results were evidence of moderate quality. Therefore, more systemically well-designed clinical studies are needed about the safe use of a sedative medicines (drugs).

The purpose of this study was to examine the relationship between the lifestyle of dental consumers and their hospital satisfaction level in an attempt to lay the foundation for successful dental marketing strategy setting. The subjects in this study were 720 medical consumers who visited dental institutions in Jeolla buk-do province. A survey was conducted from October 1 to December 1, 2006, with self-administered questionnaires. The collected data were analyzed with SPSS(Statistical Package for the Social Science) 12.0 program to find out their lifestyle and hospital satisfaction level. Concerning the impact of lifestyle on satisfaction with dental institutions, lifestyle made a difference to the satisfaction level of the hospital users with promptness and economicality(p < 0.001). As to connections between hospital-reuse intention and satisfaction level, those who were willing to reuse the dental institutions they had visited expressed better satisfaction with promptness(p < 0.05). As for links between health-related lifestyle and hospital satisfaction level, health conscious style, health promoting style health unconscious styles had a statistically significantly positive relationship to hospital satisfaction level, which showed a significant relationship between the three lifestyles and hospital satisfaction level. As for factors affecting reuse of dental institutions, it's found that their intention to reuse the same dental institution they had visited was linked to their satisfaction level with it, what made them choose it and their health-related lifestyle. In the future, more precise and in-depth questionnaires should be developed to analyze the health-related lifestyle of medical consumers.

Background: Recently, in addition to multi-drug resistant tuberculosis (MDR-TB), extensively drug-resistant tuberculosis (XDR-TB) has become rapidly growing public health threat. This study examined the clinical differences between pulmonary TB patients with extensively drug resistance (XDR) and multi-drug resistance (MDR) at the National Medical Center in Korea in order to determine the clinical characteristics associated more with XDR-TB than MDR-TB. Methods: Patients who received a diagnosis of culture-confirmed pulmonary TB and a drug sensitivity test (DST) for anti-TB drugs at the National Medical Center between January 2000 and August 2007 were enrolled in this study. The patients were identified into the XDR-TB or MDR-TB group according to the DST results. The clinical characteristics were reviewed retrospectively from the medical records. Statistical analysis for the comparisons was performed using a ${\chi}^2$-test, independent samples t-test or binary logistic regression where appropriate. Results: A total 314 patients with culture-confirmed pulmonary TB were included. Among them, 18 patients (5.7%) had XDR-TB and 69 patients (22%) had MDR-TB excluding XDR-TB. A comparison of the clinical characteristics, revealed the XDR-TB group to have a higher frequency of a prior pulmonary resection for the treatment of TB (odds ratio [OR], 3.974; 95% confidence interval [CI], 1.052~15.011; P value 0.032) and longer average previous treatment duration with anti-TB drugs, including a treatment interruption period prior to the diagnosis of XDR, than the MDR-TB group (XDR-TB group, 72.67 months; MDR-TB group, 13.09 months; average treatment duration difference between two groups, 59.582 months; 95% CI, 31.743~87.420; P value, 0.000). In addition, a longer previous treatment duration with anti-TB drugs was significantly associated with XDR-TB (OR, 1.076; 95% CI, 1.038~1.117; P value, 0.000). A comparison of the other clinical characteristics revealed the XDR-TB group to have a higher frequency of male gender, diabetes mellitus (DM), age under 45, treatment interruption history, cavitations on simple chest radiograph and positive result of sputum AFB staining at the time of diagnosis of XDR. However, the association was not statistically significant. Conclusion: Pulmonary TB patients with XDR have a higher frequency of a prior pulmonary resection and longer previous treatment duration with anti-TB drugs than those with MDR. In addition, a longer previous treatment duration with anti-TB drugs is significantly associated with XDR-TB.

Multithreaded models improve the efficiency of parallel systems by combining inner parallelism, asynchronous data availability and the locality of von Neumann model. This model executes thread code which is generated by compiler and of which quality is given by the method of generation. But multithreaded models have the demerit that execution model is restricted to a specific platform. On the contrary, Java has the platform independency, so if we can translate from threads code to Java bytecode, we can use the advantages of multithreaded models in many platforms. Java executes Java bytecode which is intermediate language format for Java virtual machine. Java bytecode plays a role of an intermediate language in translator and Java virtual machine work as back-end in translator. But, Java bytecode which is translated from multithreaded models have the demerit that it is not secure. This paper, multhithread code whose feature of platform independent can execute in java virtual machine. We design and implement translator which translate from thread code of multithreaded code to Java bytecode and which check secure problems from Java bytecode.

The purpose of this study was to provide the basic data for preventing dental caries, and maintaining and enhancing oral health. The subjects of this study were 138 male and female students who were in the 6th grade of elementary schools in Gimpo city. This study investigated the number of decayed tooth and the factors related to the number of decayed tooth, by using the results of questionnaire and oral health survey over such subjects. So, this study obtained the following conclusions. 1. For the number of decayed tooth, 'nothing(D = 0)' was the highest as 37.7%, and 'from two to three' was 23.9%, 'more than four' was 21%, and 'one' was 17.4% in order. 2. For the frequency of visiting dental clinics within the last one year, 'one to two times' was the highest as 52.2%, and the children who have not visited dental clinics even one time during one year were 23.9%. 3. For average daily tooth brushing frequency, 'two times' was the highest as 71.7%. For the use of oral health devices besides toothbrushes, 'I don't use' was the highest as 54.3%. For the experience of sealant and fluoride application, 'nothing' was the highest as 86.9% and 71.3% respectively. For the recognition on the use of fluoride dentifrice, 'I don't know' was the highest as 66.9%. 4. The socio-demographic factors related to the number of decayed tooth were mother's age, mother's background, mother's employment, and after-school fosterer(p > 0.05). 5. The oral health care factors related to the number of decayed tooth were average daily tooth brushing frequency, the use of oral health devices besides toothbrushes, and the experience of fluoride application.(p > 0.05) 6. The snack intake factors related to the number of decayed tooth were tooth care foods intake frequency and decaying foods intake frequency(p > 0.05). 7. The oral health belief item related to the number of decayed tooth was susceptibility(p > 0.05). 8. According to the results of regression analysis, the less mother was employed, the more the average daily tooth brushing frequency was, the more the tooth care foods intake frequency was, the less the decaying foods intake frequency was, and the higher susceptibility was, the lower the number of decayed tooth. 9. In order to prevent and cure early the dental caries which occur frequently in elementary school students, the establishment of oral health centers within schools should be expanded to promote tooth brushing instruction, fluoride solution rinsing, diet control, periodic oral examination.

As various state restrictions on individual freedom were imposed during the COVID-19 pandemic, concerns have been raised that excessive infringements on fundamental rights were indiscriminately permitted based on the public interest of preventing infectious diseases. Therefore, the question of how to set acceptable limits of liberty restrictions on individuals has emerged. However, since the phenomenon of infections spreading to the population is only predicted statistically, how to deal with the risk of the infected individual as a subject of legal analysis has become a problem. In the absence of a theoretical framework of legal analysis of risk, the risk of infected individuals during the pandemic was not analyzed strictly, and proportionality review of infection prevention measures was often only an abstract comparison of the importance of public interest and individual rights. Therefore, this research aims to conduct a theoretical review on how risk can be conceptualized legally in a public health crisis, and to develop a theoretical framework for proportionality review of the risk of liberty-limiting measures during a pandemic. Chapter 2 analyzes the legal philosophical concepts of risk, which are the basis for liberty restrictions during a public health crisis, and applies and extends them to the pandemic. Chapter 3 reviews previous studies related to liberty restriction measures in the context of the COVID-19 pandemic, and points out they have a limitation that specific criteria for the proportionality review of public health measures in the pandemic have not been presented. Accordingly, Chapter 3 specifies the methodological framework for proportionality review, referring to the theoretical discussion on risks in Chapter 2. Chapter 4 reviews the legitimacy of gathering restriction orders, applying the theoretical discussion in Chapter 2 and the criteria for proportionality review established in Chapter 3. In particular, Section 4 examines logic of proportionality review in judicial precedents over the ban on gathering restrictions implemented in the COVID-19 pandemic. In analyzing the precedents, the logic of proportionality review in each case is critically reviewed and reconstructed based on the theoretical framework presented in this research.
