Human history shows diverse strategies for survival and prosperity. This study introduces the concept of the expansion of wealth as a key to explain choice and behavior of political entities. American scholar, -Bruce Bueno de Mesquita-, offers theoretical grounds for this concept in that the cores of selectorate theory is settled. The political entity consists of two groups, -the winning coalition that has power to replace leader and non-winning coalition that has not. Leaders implement policies serving for the welfare of winning coalition in return for their loyalty. Both internal problems caused by demographic changes and external ones of climate changes, epidemic disease, or invasion compel leader and winning coalition to adopt policies of expansion that they believe may lead to the acquisition of wealth needed to counter those problems. The process starts by occupying one spot where other entities reside and then connecting it to its own. The line between spots functions as a foothold to form a new line to other spots. By repeating this process, a space is created in which new laws and orders are instated. In the early stage of expansion, war is hardly avoidable. Once finished successfully, the political circumstance tilts to encourage economic activities in order to generate national revenues to strengthen political power of winning coalition. However, as scale of economic activities grows, so does political power of civic classes in production and trade. To gain financial support required to run the political entity, delegation of power or bestowing autonomy to non-winning coalition is inevitable. Thus, expansion is not the ultimate solution, only to prolong the political survival if succeed. Maritime power came to attractive option when overland expansion had become obstructed. It offered much greater advantages in terms of political risks and financial burdens in exploring new regions of precious commodities than overland expansion. Each political entity around world have been, for the first time in human history, connected by maritime means since 15th century. It is worthy of noting that land conditions propelled people out to sea. Political and economic situations created opportunities to exploit geographical position in pursuit of wealth. In the 21st century, we witness the operation of international winning coalition that presides over the rules of expansion. Competing for market is synonymous to the expansion in this era, the cause and aim of it has not been changed though. Energy and dollars are key factors of expansion since the end of the 2nd world war. No matter what the forms and conditions change, naval power is still the most relevant means for expansion as it retains unique characters of maneuver, flexibility, continuity, display and projection of power. The strategy for using naval power should be in line with two different approaches for expansion: Approaches to the international winning coalition by making contribution to world order, and approaches to the non-international winning coalition by enhancing military diplomatic activities. The former will serve our share of winning coalition while the latter will open chances to acquire further prosperity.

Park Myoung Jin (1903-1957) was a respectable leader who disseminated dental medical education to make our path as the leading dental medical education developing a new global history of dental medicine. Dr. Park was born in Seoul on 3 July 1903. He graduated Kyongseong dental medical school and studied at the pharmacology department achieving his M.D. In 1938, as the president representing the Hanseong dentists association equivalent to the Japanese dentists association, Dr. Park participated in various events. After liberation, Dr. Park tried his best to achieve Korean dental medical education as the pursuit of ideal ego with self-centered ego. He reorganized the Kyongseong dental medical school and incorporated it to the Seoul National University dental college. Even during the Korea war, Dr. Park still sincerely carried out his duties as the director of the Seoul National University dental medical college by recruiting university entrants and turned out graduates. In 1954, Dr. Park as the director of the Seoul National University dental medical college, he frontiered an opportunity to adapt the American dental medicine by sending school staffs to study overseas. On 25 June 1954, Dr. Park received 25 years of meritorius service award presented by Seoul National University Dental Medical College. Further, on 6 Aril 1954, Dr. Park became a member of an academic research committee. In April 1946, Dr. Park was elected as the president of the Chosun Dentists Association(Korean Dental Association). On 19 May 1947, Dr. Park was also appointed as the director of the Korea dental medicine association leading the general meetings and academic conferences from 2nd through the 8th sessions. On 30 November 1954, as the president of the Korea dental medicine association, Dr. Park also published the Korea dental association publications. In 1957, Dr. Park donated the school housing for the principle of the Kyongseong dental medical school establishing the basis for the Korea dentists association center. Dr. Park also participated in establishment of the oral hygiene campaigne, dental administration policy, organization of the specialized subject delegation board members and the dental materials association. On 10 December 1955, we can recognize Dr. Park's respective historical consciousness through his declaration 'history is a true record of historical traces of a national'. Dr. Park was a living witness of the Korean dental industry. Especially, he stated that the origin of the Korean dentists association was in the Hanseong dentists association. Dr. Park overcame the pressure and indignity during the Japanese colonization. The joy of liberation did not last long since he also had to experience the fraticidal tragedy of the Korea war. Dr. Park was a professional dental specialist and a leader researching dental medicine. He was a great leader who understood the dental medicine and dedicated for the dentist association and dental medicine association with compassion for the nation and national as a Korean.

This study empirically examines the relationship between the characteristics of a company and its performance through open innovation. It was intended to accept open innovation as a strategic means to overcome various situations in which companies faced and to understand it as a process of generating corporate performance. In various situations, companies must overcome environmental and internal factors. As an environmental factor, the dynamics of the market and the dynamics of technology allow for the adoption of open innovation, which in turn becomes a strategic tool for generating results. In addition, the internal environment of the company should strengthen the organization's capacity considering the characteristics of the company. In order to reinforce entrepreneurial orientation, openness of organizational culture, delegation and R & D capabilities, which are internal characteristics of the company, open innovation has a positive effect on the performance of the company. In overcoming the environment given to the company, open innovation was found to be an important medium for generating various results for the company. For this study, we conducted a structured questionnaire survey on 176 Korean companies. This study suggests that open innovation is strategically accepted and understood as a management strategic philosophy in order to overcome the environment in which a company is faced and generate results.

Implant procedure belongs to so called a commercialized medical treatment, its procedure is simple and clear, and the possibility of success is almost 100%. In addition, it is a selective method rather than an inevitable method for a patient's health, so the importance of liability for explanation is especially emphasized for protection of autonomous decisions by patients. Considering these characteristics, the plaintiff in the relevant case said that the contract of implant procedure has the characteristic of subcontract, and only the failure of implant itself and the violation of liability for explanation should be the defendant's fault liability. In addition, although the above procedure contract is considered as delegation rather than subcontract, whether it's the defendant's malpractice should be judged by general people's common sense rather than average people in the industry. Therefore, if all the implanted teeth were removed due to bleeding and pains, and the patient suffered from dysaesthesia during the process, the defendant's malpractice is fully proved. When the judgements of implant medical malpractice were researched, the court doesn't consider implant contract as subcontract, but it judges dentist's malpractice by whether the implant itself is successful, so it seems that the court acknowledges similar characteristics with subcontract whose purpose is completion of work to some degree. In addition, considering the detailed contents of presented medical malpractices, it seems that judging medical malpractice is based on the common sense of general people. Therefore, the argument of the plaintiff is valid when the fact the adjustment amount is relevant to the amount that the plaintiff initially claimed is considered even though the relevant case was decided to be compulsory mediation.

This study analyzed the factors related to the job satisfaction and turnover rate of students in the skin care contract department, and suggested ways to enhance long-term employee retention. Frequency analysis and multiple regression analysis were performed using the SPSS statistical program and based on the survey data of 260 skin care contract students. The main results were as follows. First, contract students had high job satisfaction because of sufficient in-service training during the internship and also received the authority to perform the job duties of their positions. Second, the regular technical education for the job of contract students gave them confidence in job performance and job confidence, which led to long-term employee retention. Third, contractual students' turnover was reduced by applying compensation such as incentives, awards, and promotion opportunities in accordance with their work performance. Therefore, the results of the study suggest that compensation based on job performance, and the confidence in job performance of skin care contract students, can lead to increased job satisfaction, a reduced turnover rate and better long-term employee retention.

In the health care system, medical fee payment is a very important and basic factor. The National Health Insurance Act adopted a contract system, and the content of the contract is to be determined the unit price per relative value scale. Accordingly, in the National Health Insurance system, the costs of health care benefits are adjusted each year according to inflation or changes in economic conditions. On the other hand, in the Medical Care Assistance system, the Medical Care Assistance Act does not prescribe the method of determining the medical payment, and all matters are delegated to the Minister of Health and Welfare. Accordingly, the Minister has adopted a fixed-payment system for hemodialysis treatment since 2001. A constitutional petition was filed in 2017 against this fixed-payment system, and the Constitutional Court rejected the petition in 2020. In this study, we examine the meaning and content of the medical fee payment system, focusing on the above constitutional petition case, and present three principles as constitutional limits on the system. The first of its principles is the principle of legality, the second is the principle of prohibition of comprehensive delegation, and the third is the principle of proportionality. From that point of view, There are many unconstitutional elements in the fixed-payment system on hemodialysis.

In a Broadcast Encryption System, a sender sends an encrypted message to a large set of receivers at once over an insecure channel and it enables only users in a target set to decrypt the message with their private keys. In 2005, Boneh et al. proposed a fully collusion-resistant public key broadcast encryption in which the ciphertext and the privatekey sizes are constant. In general, pairing-based broadcast encryption system is efficient in bandwidth and storing aspects than non-pairing based broadcast encryption system, however, it requires many computational costs that resource-constrained devices is not suit to be applied. In this paper, we propose a Broadcast Encryption scheme(called BEWD) that user can decrypt a ciphertext more efficiently. The scheme is based on Boneh et al.scheme. More precisely, it reduces receiver's computational costs by delegating pairing computation to a proxy server which computation is required to receiver in Boneh et al.scheme. Furthermore, the scheme enables a user to check if the proxy server compute correctly. We show that our scheme is secure against selective IND-RCCA adversaries under l-BDHE assumption.

The purpose of this research is to study the impact of a consulting-recipient company's organizational characteristics have on consulting performance based on a case study of M manufacturing company that received HR consulting. Noticing that the subject company received HR consulting, consulting performance was evaluated in terms of two variables, HR effectiveness and organizational commitment, and the research focused on analyzing HR system improvement and change in awareness of employees. The result showed that all lower factors that describe organizational characteristics - closeness, delegation of responsibilities, ethical management, communication and shared values - had statistically positive impact on HR effectiveness at significance level p<.05. Also, the higher the HR effectiveness, the higher the positive impact on organizational commitment improvement. Moreover, it was shown that all lower factors in organizational characteristics had positive impact on overall consulting performance. Accordingly, the research concludes that, in order to improve consulting performance, i.e., HR effectiveness and organizational commitment, for blue collar workers, the company needs to create a family-oriented and closely-knit working environment, establish rules and systems to delegate responsibilities appropriately, actively promote ethical management and provide strategic activities to facilitate effective communication.
