Purpose: The purpose of this study examines the mediating effect of clan leadership in the relationship between hierarchy culture and organizational commitment. Most previous research focused on the relationship between organizational culture and organizational performance or organizational culture and job satisfaction. There are few empirical studies that focus on organizational commitment data because it is difficult to collect in many cases of export-driven small and medium sized enterprises. However, this research measures affective commitment, continuance commitment, and normative commitment differently than previous research, which is mostly focused on the hierarchy culture, clan leadership, and organizational commitment measurements. Research design, data, methodology: Conceptual research model is based on the studies of Cameron and Quinn (2011), and Gungor and Sahin (2018). The model is designed with three constructs such as hierarchy culture, organizational commitment, and clan leadership. The monitor culture and coordinator culture are as proxy for the hierarchy culture. The affective commitment, continuance commitment, and normative commitment are as proxy for the organizational commitment. And also the facilitator leadership and mentor leadership are as proxy for the clan leadership. Based on three hundred cases such as export-driven small and medium sized enterprises (SMEs), this study verify the hypothesis. Hypothesis was analyzed with the structural equation modeling. Results: In case of export-driven small and medium sized enterprises (SMEs), clan leadership acts as a mediator in the relationship between hierarchy culture and organizational commitment. In case of export-driven small and medium sized enterprises (SMEs) with high organizational commitment, clan leadership acts as a mediator in the relationship between hierarchy culture and organizational commitment. In case of export-driven small and medium sized enterprises (SMEs) with low organizational commitment, clan leadership did not act as a mediator in the relationship between hierarchy culture and organizational commitment. Conclusions: By controlling for the mediating effect of clan culture, this study have improved the academic contributions as well as policy and practical implications through empirical study of clan leadership that affect organizational commitment in the fields of hierarchy culture. In addition, this study means that the mediating effects on the variables of clan leadership were examined.

Purpose: The aim of this review is to comprehensively summarize the definition of vitamin D as a nutrient as well as a hormone-like molecule and its new function in prevention of various chronic diseases. Methods: The review was written by the method for systematic reivew writing. Literatures from the various sources, including research articles, book chapters, proceedings and electronic materials as appropriate, were screened first and then reviewed and analyzed for the review. Results: Vitamin D was originally considered as the essential nutrient as a vital carbon compound and was first discovered among children with osteomalacia, also known as ricket disease, characterized by poorly calcified bones which were easily bent rather than broken. Since that time, vitamin D has been known as the key nutrient to improve bone health. However, recently emerging study findings have shown that vitamin D acts as the hormone-like nutrient since it is synthesized like a hormone when our body needs and this particular vitamin also acts like a cell signaling ligand which regulates gene expression of various proteins. So far positive effects of vitamin D have been suggested for the action of anticancer, anti-immune function, and anti-cardiovascular disease, as well as antidiabetic function, etc. In this review, the definition for vitamin D as a nutrient vitamin as well as a hormone-like molecule, cell signaling mechanism of vitamin D, and finally the potential role for the prevention of chronic diseases are discussed. Conclusion: Vitamin D is now being considered as a vital nutrient as a vitamin and as a potential substance for prevention of several chronic diseases.

대화에서 화자의 의도는 감정, 화행, 그리고 서술자로 표현될 수 있다. 따라서 사용자 질의에 정확하게 응답하기 위해서 대화 시스템은 발화에 내포된 감정, 화행, 그리고 서술자를 파악해야한다. 많은 이전 연구들은 감정, 화행, 서술자를 독립된 분류 문제로 다뤄왔다. 그러나 몇몇 연구에서는 감정, 화행, 서술자가 서로 연관되어 있음을 보였다. 본 논문에서는 Convolutional Neural Netowork를 이용하여 감정, 화행, 서술자를 동시에 분석하는 통합 모델을 제안한다. 제안 모델은 특정 추상화 계층과, 공유 추상화 계층으로 구성된다. 특정 추상화 계층에서는 감정, 화행, 서술자의 독립된 정보가 추출되고 공유 추상화 계층에서 독립된 정보들의 조합이 추상화된다. 학습 시 감정의 오류, 화행의 오류, 서술자의 오류는 부분적으로 역 전파 된다. 제안한 통합 모델은 실험에서 독립된 모델보다 좋은 성능(감정 +2%p, 화행 +11%p, 서술자 +3%)을 보였다.

민간경비업무의 공공성에 따른 행정규제의 필요성과 그에 따른 실질적 감독의 이행은 민간경비업계의 전문성과 대국민적 서비스의 질적 향상을 담보하게 된다. 이러한 국가적 규제와 감독의 이면에는 업계의 자율적 책임 이행을 내포하고 있으며 그러한 자체적인 업무 수행이 이루어지지 않을 경우에는 국가는 반드시 그 책임을 강제한다는 것이다. 따라서 자체적인 치유능력의 신장과 그 근간을 이루기 위해서는 현행 행정 규제 및 감독은 강화되어야 하며 그러한 내용을 경비업법상 명시하여야 한다. 본 연구는 그러한 실효성을 확보하기 위한 방안으로 다음과 같이 제시한다. 첫째, 경비업의 허가는 그 규제의 우선적 장치로서 자격 요건과 심사절차를 엄격히 하여야 한다. 둘째, 허가 이후에 지속적인 감독이 이루어지지 않으면 그 취지가 희석되므로 민간경비 관련 감독기관을 독립적으로 운영하여 실질적인 이행을 담보하여야 한다. 셋째, 허위 또는 부당한 방법에 의한 허가 취득과 위법${\cdot}$부당한 도급업무 수행 및 경비지도사 선임의 편법적 행위는 그 처벌이 강화 되어야 한다. 넷째, 민간경비 업계의 자체적인 의무 이행을 담보하기 위해서 뿐만 아니라 형식적인 경비지도사제도의 단점을 보완하기 위해서 전문자격증제도를 도입하여 한다.

Pulpotomy is a frequently used treatment modality in primary teeth. It is method by which infected coronal pulp is removed while retaining vital radicular pulp. Since its introduction in 1930 by Sweet formocresol remains the most popular medicament for this treatment. However, despite its outstanding bactericidal properties, formocresol is known to cause adverse tissue reactions. Theoretically, formocresol disinfects and fixes radicular pulp and thus prevents infection and internal resorption. In reality, however, it leads to chronic inflammation and is sometimes responsible for failures through abscess formation and internal root resorption. Also, Myers et al., in 1978, reported on the systemic distribution of FC and other studies have followed with reports of its immunological, mutagenic and carcinogenic effects. Much effort has, therefore, focused on the development of alternative medicaments and techniques. Since its introduction in 19C, ferric sulfate proven itself as an effective hemostatic agent and is used as an astringent in dentistry. In 1988, Landau and Johnsen suggested ferric sulfate be used as a medicament in pulpotomy and many studies have focused on it to overcome the toxic effects of FC. Ferric sulfate acts through its ferric ion and iron ion, which react with blood protein leading to aggregation. The aggregated protein acts to plug the blood vessels, causing mechanical hemostasis. As blood clot formation is minimal, there is reduced inflammation of radicular pulp and enhanced healing. There are no reports regarding its systemic distribution. This is a report of cases treated by the author using pulpotomy with ferric sulfate.
