Dentists and dental hygienists are major collaborators, as expressed by the concept of "Four-handed dentistry." Dentists are guaranteed their legal duties and rights in accordance with the Medical Act, whereas dental hygienists are currently stipulated in the scope of their legal duties under the Act on Medical Technicians. However, there is a difference between the actual work and the legal work performed by dental hygienists; therefore, the work is dependent on many legal controversies and authoritative interpretations. The purpose of this study is, first, to develop a reliable questionnaire tool regarding the actual work performed by dental hygienists in dental hospitals and clinics, and second, to examine the awareness of the appropriateness of legal work based on the developed questionnaire. The target subjects of the survey were dental hygienists and dentists, and the dental hygienists were those who worked in dental hospitals and clinics as license reporters of the Korean Dental Hygienists Association. A total of 1,294 dental hygienists and 39 dentists were included in the final analysis. In the dental hygienist group, 19 items received the response "appropriate for legal work" in over 90% of cases, accounting for 25% of the total 76 items. In addition, in a total of 31 items, more than 80% of the responses were appropriate for legal work. Among them, the highest was 'Scailing' (97.7%), followed by "Extraoral-Panorama" (97.1%). In the dentist group, 10 out of 76 items showed over 90% adequacy for legal work, and among them, "instrument cleaning and sterilization" was the highest at 100%. It was followed by "Intraoral radiography," "Scailing," and "Toothpick method, TPM" with 97.4%. In the case of dentists, 28 out of a total of 76 items showed an appropriateness of more than 80% for legal work. This study comprehensively investigated the actual work of dental hygienists in line with timely and appropriate social issues and provided reliable statistics in evidence-based dentistry.

The task of defining the concept of 'disability' has proven to be surprisingly difficult. The way disability is assessed in the world suggests that very different conceptions of disability are being presumed. It is very hard to suggest appropriate criteria for assessing a disability that accurately demonstrates the presence and measures the severity of the disability, with proven consistency and validity provided by the assessors consuming the time and cost that the society can afford. When a rigorous framework in disability assessment procedures is used, discretion is then considerably restricted. Limited discretion tends to produce more consistency and validity in the assessment but at the cost of ignoring the individual differences or exceptional circumstances. The disability approach among the categories of the disability assessment is both the oldest and the most commonly used strategy of disability assessment around the world. Most of the criteria of disability assessment in Korea belongs to this. The McBride's criteria for disability evaluations can be used to obtain the ratio of body impairment and work disability without spending too much time and is being applied in court. Nevertheless, there are many errors and controversies, and corrections are required. On the other hand, an improvement plan for a disability evaluation method in Korea is to supplement and use the McBride's disability assessment method, which is currently the most widely used. This review article describes the conception of disability and the assessment of disability, and introduces the models of the assessment of disability to determine if the application of the McBride's criteria of disability evaluation can be justified.

Manual therapy has undergone parallel development throughout many parts of the world dating back to ancient times for at least 2,500 years. The earliest historical reference to the practice of manual therapy in Greece, dates back to 400 B.C. Over the centuries, manual medicines have fallen in and out of favor with the medical profession. To truly understand the principle, it is important to know that manual therapy was initially the mainstay of the three leading alternative health care systems, osteopathy, chiropractic, and most notably physical therapy. These were all founded in the latter part of the 19th century in response to the shortcomings in allopathic medicine. Although it has been around for a long time and has been used all over the world, there are a few reports on manual therapy treatment, and most papers provided a low level of evidence. Despite the controversies over manual therapy, its use appears to be increasing gradually. This article reviews the history of manual therapy from ancient times to the present including Korean history, discusses the current state of knowledge on manual therapy, and informs physicians who manage musculoskeletal pain.

In accordance with Article 15 of the Medical Law, medical personnel in Korea cannot refuse treatment of a patient unless there is a justifiable reason, and violation of this obligations is subject to criminal penalties. Japan also stipulates the same content in the law. However, this violation of obligations in Japan is not subject to criminal penalties, and is used as a judgment element of the liability for damages of doctors only in the case of damage to the patient. However, in both countries, it is difficult to interpret and apply the law because the regulation is a little ambiguous. In particular, the key is to find out what is the justifiable reason for the doctor to refuse treatment of the patient. Recently, Japan has completed the work of re-examining the discussion on medical refusal from a modern perspective in terms of improving the excessive working environment of doctors. On the other hand, in Korea, it is not clear in what cases it is possible to refuse treatment. because there is a lack of systematic discussion on medical refusal. Rather, unnecessary misunderstandings and controversies have resulted in the loss of trust between patients and doctors. In Korea, there is already a legal right for a doctor to reject it according to his religious beliefs or conscience in the implementation of the suspension of life-sustaining treatment decisions. And in the case of an abortion, debates are underway that doctors should be given the right to refuse it. This study introduces the current state of discussion in Japan, and examines the issues surrounding medical refusal in Korea. It is hoped that this study will facilitate further discussions on the medical refusal.

While there are a few ways of giving meanings to the term, "Altai" ranging from a language family to a national residing around the Altai Mountains in Russian Federation, and to the people speaking the language or the whole area where they live, there have been controversial debates whether it is a meaningful categorization. This paper argues that the basic cause lying beneath the controversies is the underdevelopment of the subject that identifies itself as a representative of the whole area where the Altaic language family is spoken. It might be true, as some Korean and Russian scholars insist, that what deserves to be called Altaic culture (or civilization) has provided a common culture and mutual interactions with the people. However, the Altaic people failed to constitute themselves as a meaningful modern group, that is a nation, and they did not fully develop national consciousness, As a result, although their way of life may be regarded as an origin of various cultures across North-East Asia, Altaic culture is not sufficient to give a momentum to claim for cultural initiative in the region. This comes at least partly from the reconfiguration of ethnic identity through a Soviet type of modernization and its geopolitical situation surrounded by super-powers such as China and Russia, as well as belated import of religions such as Buddhism and Christianity. From a wide perspective, the trouble about delimiting an area is not unique in Altai, but universally found in anywhere, as far as area studies are concerned. The delimitation of an area is not a natural outcome of physical environment but an artificial production of how cultural-political relationships have been distributed. Therefore, while the case of Alai has its own specificities, its implications that a national or regional boundary in area studies should not be taken for granted may be applied to other areas.

Along with concerns about deteriorating social and economic status of teachers around the world, Master Teacher System(MTS) has been considered as one of the alternatives to transform teaching profession into a more attractive job. In this study, the conditions and problems associated with the MTS in China is analyzed to draw implications for South Korea, which recently legalized the MTS. Research framework including four research questions is developed based on the controversies surrounding MTS of South Korea. The main findings show that the MTS in China was introduced to improve teachers' social and economic status along with the quality of prospective teachers. A very small number of master teachers are selected through rigorous standards including longer service period. They are given additional monetary and non-monetary compensations in return for their teaching-learning leadership and responsibilities. As highly respected educators, they enjoy the lifelong benefits, although they are annually evaluated. It is evident that the MTS has contributed to improving the attractiveness of teaching profession in China. Nevertheless, there are many problems associated with selection standards and methods of master teachers, their roles, compensation, evaluation and terms of service. Recent criticism due to changing circumstances surrounding education in China makes the MTS more questionable. Based on the findings, major implications for future directions of MTS of South Korea are drawn and suggested.

This paper studies the impact of regulatory approaches on innovation and entrepreneurship. As technological progress and environmental changes avail new business opportunities to innovative startups, many governments find it difficult to regulate new and unprecedented businesses promoted by the innovative firms. In order to provide academic and practitional implications on the regulatory design with which to support innovation and entrepreneurship, this paper aims to review classical theories on the demand and supply of regulation as well as empirical research on the impact of regulation on market entry and incentives for innovation. Based on the findings, this paper discusses the recent controversies around the regulatory approaches on new businesses pursued by startups, which are as known as the "positive regulatory approach" vs. "negative regulatory approaches" among practitioners and policy makers in Korea. This paper claims that the Korean context provides an useful opportunity to investigate how the ongoing transition of the once "fast follower" economy into a pacesetter one changes the nature of businesses pursued by firms, investors, and related market players and, accordingly, calls for the changes in the way the government intervenes in markets to regulate businesses of firms. By doing so, this paper sheds light on the role of the government in establishing an entrepreneurial ecosystem where innovative ideas of startups can be tested and nurtured.

Background: Pulmonary atresia with intact ventricular septum is a rare congenital cardiac disease. There have been various surgical options, but there are still controversies. Material and Method: Fourteen neonates who were operated on between 1999 and 2000 were enrolled in this study. We measured Z-value of tricuspid valve by echocardiography. We performed right ventricular outflow tract transannular patch in 9 patients. Modified Blalock-Taussig shunt was placed according to the condition of patients. Mean follow up period was 46.0 months. Result: There were 2 operative mortality and 1 late mortality. Biventricular repair was possible in 7 patients. One and a half ventricular repair were done in 3 (tricuspid valve Z-value was -2, -2.5 and -3) and single ventricular repair in 2 patients (tricuspid z-value was -4.6, -4.5) The tricuspid valve Z-value for the patients who had biventricular repair and one and a half ventricular repair were -0.8$\pm$1.50 (-3.2$\∼$1.2) and -2.5$\∼$0.5 (-3$\∼$ -2) respectively. All patients who survived had fair to good right ventricular function, good left ventricular function and good clinical states. Conclusion: Neonatal surgical management of pulmonary atresia with intact ventricular septum has a good surgical outcome, z-value of tricuspid may be helpful for the determination of surgical options.

Knowledge regarding the resilience factors and risk factors of the childhood trauma on the developental trajectory is in its infancy due to the lack of prospective follow-up studies in the childhood trauma and limited understanding of the complex reciprocal interactions between childhood trauma, develop-ent and various aspects of children's environment. These difficulties in the conceptual framework and research methods in the childhood trauma are partly reflected in the inconsistencies, even controversies, of the results in the childhood trauma researches. Despite these difficulties, common aspects of the risk factors and resilience of the childhood trauma on the development can be identified from the previous studies. The resilience to the negative outcome on the development by childhood trauma includes：sex female before puberty, male after puberty or infancy), high socioeconomic status, no organic problem, easy temperament, no previous experience with early loss or separation, younger age at the trauma, better problem solving capacity, high self-esteem, internal locus of control, high coping skills, ability to identify interpersonal relationships, ability to play, sense of humor, having capable parents, having a warm relaionship with at least one of the parents, high education and participating in the organized religious activities. These commonalities of the results suggest that risk and resilient factors of the childhood trauma are interdependent, each factor has multiplicity in the impacts on the children's development according to the developmental stage of the child, family and children's other environment, trauma and stressor have diverse effects according to their intensity and risk and resilience factors could have synergistic or antagonistic effects to each other. To develop comprehensive understanding on the relationship between childhood trauma and developmental psychopathology, risk and resilience factors and to develop effective and efficient prevention and intervention, research on the effect of the stress on the neurodevelopment, on the individual differences of the response to the trauma including genetic factors and constitution, and on the brain plasticity should be accompanied in the future.

Background: There have been controversies whether mitral valvular surgery is necessary in the patients with moderate ischemic mitral regurgitation undergoing coronary artery bypass grafting. The purpose of this study is to evaluate the long term clinical results of patients with moderate ischemic mitral regurgitation. Material and Method: Between January 1992 and February 2005, 44 patients with moderate ischemic mitral regurgitation underwent coronary artery bypass grafting. Concomitant mitral valvular procedure was performed in 20 patients (group 1) and isolated coronary artery bypass grafting was performed in 24 patients (group 2). There were no significant difference between groups except cardiopulmonary bypass time (p<0.01). Postoperative follow up duration was $30.1{\pm}29.6$ months and last follow up echocardiographic examination was performed at $21.2{\pm}28.0$ months. Result: There was no difference in operative mortality between groups (group 1 vs group 2, 15.0% vs 8.3%, p=0.493). Grade of mitral regurgitation ${(0.81{\pm}0.91\;vs\;1.50{\pm}0.05,\;p=0.046)}$ and reduction in regurgitation grade ${(1.75{\pm}0.93\;vs\;0.70{\pm}1.26,\;p=0.009)}$ were different between two groups. But there were no significant differences in left ventricular ejection fraction ${(34.1{\pm}11.4%\;vs\;41.6{\pm}12.9%)}$, left ventricular end systolic volume ${(118.2{\pm}63.9\;ml%\;vs\;85.6{\pm}281\;ml)}$, New York Heart Association functional class ${(2.1{\pm}0.2\;vs\;2.4{\pm}1.2)}$ and 5 year survival rate ${(85{\pm}8%\;vs\;82{\pm}8%)}$. There was no risk factor for operative mortality and the only risk factor for late death was preoperative atrial fibrillation (p=0.042). There was no significant correlation between mitral valvular surgery and late death. Conclusion: Concomitant mitral valvular procedure in patients with moderate ischemic mitral regurgitation undergoing coronary artery bypass grafting had no significant positive effect on survival and ventricular function compared with isolated coronary artery bypass grafting. Prospective randomized study may be needed to evaluate the necessity of concomitant mitral procedure and to find more effective method for the improvement of ventricular function.
