Following research proposes "Virtualization of Smart Cards (ViSCa)" which is a security system that aims to provide a multi-device platform for the deployment of services that require a strong security protocol, both for the access & authentication and execution of its applications and focuses on analyzing Virtualization of Smart Cards (ViSCa) platform-based mobile payment service by comparing with other similar cases. At the present day, the appearance of new ICT, the diffusion of new user devices (such as smartphones, tablet PC, and so on) and the growth of internet penetration rate are creating many world-shaking services yet in the most of these applications' private information has to be shared, which means that security breaches and illegal access to that information are real threats that have to be solved. Also mobile payment service is, one of the innovative services, has same issues which are real threats for users because mobile payment service sometimes requires user identification, an authentication procedure and confidential data sharing. Thus, an extra layer of security is needed in their communication and execution protocols. The Virtualization of Smart Cards (ViSCa), concept is a holistic approach and centralized management for a security system that pursues to provide a ubiquitous multi-device platform for the arrangement of mobile payment services that demand a powerful security protocol, both for the access & authentication and execution of its applications. In this sense, Virtualization of Smart Cards (ViSCa) offers full interoperability and full access from any user device without any loss of security. The concept prevents possible attacks by third parties, guaranteeing the confidentiality of personal data, bank accounts or private financial information. The Virtualization of Smart Cards (ViSCa) concept is split in two different phases: the execution of the user authentication protocol on the user device and the cloud architecture that executes the secure application. Thus, the secure service access is guaranteed at anytime, anywhere and through any device supporting previously required security mechanisms. The security level is improved by using virtualization technology in the cloud. This virtualization technology is used terminal virtualization to virtualize smart card hardware and thrive to manage virtualized smart cards as a whole, through mobile cloud technology in Virtualization of Smart Cards (ViSCa) platform-based mobile payment service. This entire process is referred to as Smart Card as a Service (SCaaS). Virtualization of Smart Cards (ViSCa) platform-based mobile payment service virtualizes smart card, which is used as payment mean, and loads it in to the mobile cloud. Authentication takes place through application and helps log on to mobile cloud and chooses one of virtualized smart card as a payment method. To decide the scope of the research, which is comparing Virtualization of Smart Cards (ViSCa) platform-based mobile payment service with other similar cases, we categorized the prior researches' mobile payment service groups into distinct feature and service type. Both groups store credit card's data in the mobile device and settle the payment process at the offline market. By the location where the electronic financial transaction information (data) is stored, the groups can be categorized into two main service types. First is "App Method" which loads the data in the server connected to the application. Second "Mobile Card Method" stores its data in the Integrated Circuit (IC) chip, which holds financial transaction data, which is inbuilt in the mobile device secure element (SE). Through prior researches on accept factors of mobile payment service and its market environment, we came up with six key factors of comparative analysis which are economic, generality, security, convenience(ease of use), applicability and efficiency. Within the chosen group, we compared and analyzed the selected cases and Virtualization of Smart Cards (ViSCa) platform-based mobile payment service.

This study was carried out to investigate the range of distribution and vegetation structure of habitats of genus Cymbidium which is distributed in Jeju Island, Korea. This genus is distributed in tropical and subtropical Asia and North Australia. In Korea, there are six species [i. e. C. goeringii (Rchb. f.) Rchb. f., C. kanran Makino, C. lancifolium Blume var. aspdistrifolium (Fukuy.) S. S. Ying., C. macrorhizum Lindl., C. nagifolium Masam. and C. ensifolium L.], which were also distributed in Jeju Island. The habitats of this genus ranged between 16 meter and 574 meter above sea level in Jeju Island. C. macrorhizum had the broadest altitudinal range (16-574 meter above sea level), whereas C. ensifolium, C. nagifolium and C. lancifolium var. aspidistrifolium had the narrow altitudinal range. According to the classification analysis by TWINSPAN, the plant communities were divided into five groups of Castanopsis sieboldii community, Castanopsis sieboldii-Pinus thunbergii community, Pinus thunbergii-Quercus acutissima community, Pinus thunbergii community and Quercus glauca- Aphananthe aspera community. Three species, C. kanran, C. nagifolium, and C. ensifolium inhabited Castanopsis sieboldii community and C. lancifolium var. aspdistrifolium inhabited Castanopsis sieboldii-Pinus thunbergii community. C. macrorhizum inhabited Pinus thunbergii community, Pinus thunbergii-Quercus acutissima community and Quercus glauca-Aphananthe aspera community. C. goeringii inhabitated Castanopsis sieboldii-Pinus thunbergii community and Pinus thunbergii-Quercus acutissima community. The populations of the genus Cymbidium have been extremely decreased due to illegal collection in Jeju Island. Especially, the distribution range of C. kanran, C. nagifolium, and C. ensifolium was narrow and limited to evergreen broad-leaved forests, therefore, conservation plans are needed for the protection of these species.

With the rapid evolution of technology, the size, number, and the type of databases has increased concomitantly, so data mining approaches face many challenging applications from databases. One such application is discovery of fraud patterns from agricultural product wholesale transaction instances. The agricultural product wholesale market in Korea is huge, and vast numbers of transactions have been made every day. The demand for agricultural products continues to grow, and the use of electronic auction systems raises the efficiency of operations of wholesale market. Certainly, the number of unusual transactions is also assumed to be increased in proportion to the trading amount, where an unusual transaction is often the first sign of fraud. However, it is very difficult to identify and detect these transactions and the corresponding fraud occurred in agricultural product wholesale market because the types of fraud are more intelligent than ever before. The fraud can be detected by verifying the overall transaction records manually, but it requires significant amount of human resources, and ultimately is not a practical approach. Frauds also can be revealed by victim's report or complaint. But there are usually no victims in the agricultural product wholesale frauds because they are committed by collusion of an auction company and an intermediary wholesaler. Nevertheless, it is required to monitor transaction records continuously and to make an effort to prevent any fraud, because the fraud not only disturbs the fair trade order of the market but also reduces the credibility of the market rapidly. Applying data mining to such an environment is very useful since it can discover unknown fraud patterns or features from a large volume of transaction data properly. The objective of this research is to empirically investigate the factors necessary to detect fraud transactions in an agricultural product wholesale market by developing a data mining based fraud detection model. One of major frauds is the phantom transaction, which is a colluding transaction by the seller(auction company or forwarder) and buyer(intermediary wholesaler) to commit the fraud transaction. They pretend to fulfill the transaction by recording false data in the online transaction processing system without actually selling products, and the seller receives money from the buyer. This leads to the overstatement of sales performance and illegal money transfers, which reduces the credibility of market. This paper reviews the environment of wholesale market such as types of transactions, roles of participants of the market, and various types and characteristics of frauds, and introduces the whole process of developing the phantom transaction detection model. The process consists of the following 4 modules: (1) Data cleaning and standardization (2) Statistical data analysis such as distribution and correlation analysis, (3) Construction of classification model using decision-tree induction approach, (4) Verification of the model in terms of hit ratio. We collected real data from 6 associations of agricultural producers in metropolitan markets. Final model with a decision-tree induction approach revealed that monthly average trading price of item offered by forwarders is a key variable in detecting the phantom transaction. The verification procedure also confirmed the suitability of the results. However, even though the performance of the results of this research is satisfactory, sensitive issues are still remained for improving classification accuracy and conciseness of rules. One such issue is the robustness of data mining model. Data mining is very much data-oriented, so data mining models tend to be very sensitive to changes of data or situations. Thus, it is evident that this non-robustness of data mining model requires continuous remodeling as data or situation changes. We hope that this paper suggest valuable guideline to organizations and companies that consider introducing or constructing a fraud detection model in the future.

Recently, a plastic surgery hospital in Seoul, has been raided following suspicions that ghost surgery was performed by an unauthorized substitute surgeon on a chinese woman who lapsed into a death. Following the incident, an organization to eradicate ghost surgery was created in March by Consumers Korea, founded to protect consumer rights, and the Korea Alliance of Patients Organization. The organization has received reports of illegal medical practices. To substitute another physician without the patient's consent and without his knowledge of the substitution is fraud and deceit and a violation of a basic ethical concept. The patient as a human being is entitled to choose his own physician and he should be permitted to acquiesce in or refuse to accept the substitution. It should be noted that it is the operating surgeon to whom the patient grants his consent to perform the operation. The patient is entitled to the services of the particular surgeon with whom he contracts. The surgeon, in accepting the patient, obligates himself to utilize his personal talents in the performance of the operation to the extent required by the agreement creating the physician-patient relationship. He cannot properly delegate to another the duties which the patient authorizes him to perform personally. 'Ghost surgery' comes under Article 257(Inflicting Bodily Injury on Other or on Lineal Ascendant) of the Criminal Code. Substitution another physician without the patient's consent and without his knowledge of the substitution shall be performed Inflicting Bodily Injury. This is a controversial issue that'ghost surgery' comes under Article 347(Fraud) of the Criminal Code. It maybe controversial that operation substituted by another physician without the patient's consent and without his knowledge of the substitution becomes the component of Fraud. Also, Ghost surgery' comes under Article 27 (Prohibition of Unlicensed Medical Practice, etc.), Article 22 (Medical Records, etc.), Article 33 (Establishment) of the Medical Service Act. The surgeon's obligation to the patient requires him to perform the surgical operation: (1) within the scope of authority granted him by the consent to the operation; (2) in accordance with the terms of the contractual relationship; (3) with complete disclosure of all facts relevant to the need and the performance of the operation; and (4) to utilize his best skill in performing the operation.

According to the review and analysis of medical cases that are assigned to the Supreme Court and all local High Court in 2011 and that are presented in the media, it was found that the following categories were taken seriously, medical and pharmaceutical product liability, the third principle of trust between medical institutions, negligence and causation estimation, responsibility limit, the meaning of medical records and related judgment of disturbed substantiation, Oriental doctors' duties to explain the procedures, IMS events, whether one can claim for each medical care operated by non-physician health care institutions to the nonmedical domain in the National Health Insurance Corporation, and the basis of norms for each claim. In the cases related to medical pharmaceutical product liability, Supreme Court alleviated burden of proof for accidents with medical and pharmaceutical products prior to the practice of Product Liability Law and onset the point of negative prescription as the time of damage strikes to condition feasibility of the specific situation. In the cases related to the 3rd principle of trust between medical institutions, the Supreme Court refused to sentence the doctor who has trusted the judgment of the same third-party doctors the violations of the care duty. With respect to proof of a causal relationship and damages in a medical negligence case, the Supreme Court decided that it is unjust to deny negligence by the materials of causal relationship rejecting the original verdict and clarified that the causal relationship shall not deny the reasons to limit doctors' responsibilities. In order not put burden on patients with disadvantages in which medical records and the description of the practice or the most fundamental and important evidence to prove negligence and causation are being neglected, the Supreme Court admitted in the hospital's responsibility for the case of the neonate death of suffocation without properly listed fetal heart rate and uterine contraction monitor. On the other hand, the Seoul Western District Court has admitted alimony for altering and forging medical records. With respect to doctors' obligations to description, the Supreme Court decided that it is necessary to explain the foreseen risks by the combination of oriental and western medicines emphasizing the right of patient's self-determination. However, questions have arisen whether it is realistically feasible or not. In a case of an unlicensed doctor performing intramuscular stimulation treatment (IMS), the Supreme Court put off its decision if it was an unlicensed medical practice as to put limitation of eastern and western medical practices, but it declared that IMS practice was an acupuncture treatment therefore the plaintiff's conduct being an illegal act. In the future, clear judgment on this matter should be made. With respect to the claim of bills from non-physical health care institutions, the Supreme Court decided to void it for the implementation of the arrangement is contrary to the commitments made in the medical law and therefore, it is invalid to claim. In addition, contrast to the private healthcare professionals, who are subject to redemption according to the National Healthcare Insurance Law, the Seoul High Court explicitly confirmed that the non-professionals who receive the tort operating profit must return the unjust enrichment and have the liability for damages. As mentioned above, a relatively wide range of topics were discussed in medical field of 2011. In Korea's health care environment undergoing complex changes day by day, it is expected to see more diverse and in-depth discussions striding out to the development in the field of health care.

Niphon spinosus, Epinephelus bruneus, and Epinephelus septemfasciatus are involved in the Perciformes Order and Serranidae Family. When E. bruneus and E. septemfasciatus are fully grown, the striped pattern on the body gradually disappears. Therefore, morphological classification of adult fishes is quite difficult to identify the differences to N. spinosus. In this study, we investigate the method to differentiate those using PCR. To design the primers, 16S rRNA region of N. spinosus, E. bruneus, and E. septemfasciatus registered in the GeneBank (www.ncbi.nlm.nih.gov) have been used and for the analysis, Bio Edit ver. 7.0.9.0 was used. As a result, it was design NS-003-F/NS-005-R (136 bp), EB-001-F/EB-002-R (181 bp), and ES-001-F/ES-001-R (123 bp) primers for the differentiation of each 3 different fishes. Therefore, the species-specific primer sets would be a useful tool for scientific and speedy differentiation against the illegal distribution for consumer protection.

In accordance with the rapidly growing number of street food service without a registration, a study was undertaken to determine the present state of food service by the covered wagon bar, through an investigation in Jamwondong, around the south gate market and Kangnam subway station, in Seoul, between July 25th and August 25th of 1987. The survey was comprised of three parts: 1) foodservice operation in covered wagon, 2) personal and food handling hygiene, 3) food behaviors of customers. A total of 54 covered wagon bars, consisting of 51.8% mobile bars and 48.2% non-mobile bars, operating in the above three locations, were investigated. Survey results show non-mobile covered wagon bars to be more popular among persons in their thrities and fourties than among teens or the elderly; also among males than females; among company employees and college students than others. Seventy five percent of the mobile covered wagon bars served snack type foods and others served wine and foods for wine, in contrast to hundred percent of the non-mobile covered wagon bars served wine and foods for wine. The survey found many problems of hygiene, in method of food purchasing, menu planning, food preparation, dish washing treatment of leftovers and water supply, as well as personal hygiene. However, customers prefer the casual and popular atmosphere at the counter of the covered wagon bar. Finally, the study emphasizes a need for better operation of covered wagon bar, improvement of food stuff handling and the way of food services and personal hygiene. A change of the registration system from the illegal operation are urgently needed for better quality food services of covered wagon bars.

Eighty percent of Gangweon-Do area is mountain forests, and of all others this province has the largest number of "Hwajeon-farmers" (who illegally reclaim the mountain forests to do farming as long as the soil is fertile enough to yield profit, but when it fails, move to other places to repeat the same forest burning, causing tremendous forest damages). In 1965 a 7-year plan was mapped out to exterminate this gipsy-farmers only to be suspended in 1969 to give way to the stronger urge from the national security view-point to first displace those isolated farmers set in deep mountains. In the meantime an increased number of the Hwajeon-farmers burned the forests, working new havoc. To cope with the situation, the provincial government lounched another 4-year plan in 1973 and has been enforcing the resettlement policy with renewed enthusiasm. Whether the plan will succeed depends entirely on the authority involved can solve the problems listed below with regard to the Hwajeon-farmers who are to lose their only means of survival and move down to the low-lands: 1) Their living must be taken care of until they can have definite means of self-supporting. 2) They must be provided with the opportunity to work in connection with the government-sponsored labor programs. 3) Not only the public organizations but also the private firms must give them the priority to get work. 4) The rural revitalization movement must expand the self-help reconstruction projects to absorb their labor powers. 5) The Hwajeon-farmers themselves must have the spirit of self-help and self-supporting. 6) All the citizens in the province must receive and protect them with brethren love. 7) The function of the watch-posts against the Hwajeon-farmers must be strengthened again.

From the point of view of the law and public morals in Yi-dynasty, it is possible to discover new meanings in the love of Chunhyang and Mongryong-Lee, the conflicts between Chunhyang and Hakdo-Byeon, and the rescue of Chunhyang by Mongryong-Lee as a secret royal inspector. First, although the love of Chunhyang and Mongryong-Lee was against the law and public morals of Yi-dynasty, the narrator did not call to account, but he described the love as a romantic and new one conflicting with the ruling system. And it was an unprecedented case that Chunhyang asked a written contract as a legal guarantee for marriage when Mongryong-Lee courted her. Second, Hakdo-Byeon, the Namwon county governor, accused Chunhyang, a female entertainer of the Namwon county, of disobedience to his oder and contempt of him, and interrogated her with torture when she denied his demand for bed service which was prohibited by law. Chunhyang refuted against him and regarded his demand for bed service as the rape of a married woman. In this process, narrator sharply contrasted Chunhyang's claim for human rights with Hakdo-Byeon's legal administration. Characters such as people of Namwon county and king did not call Mongryong-Lee to account for that he, as a secret royal inspector, allegedly used his power privately to rescue his sweetheart Chunhyang from Hakdo-Byeon's illegal oppression. These different judgements on legal administrations of Hakdo-Byeon and Mongryong-Lee came from the legal emotion of characters and reading publics of . Namely, people who sympathized with Chunhyang's claim for love and human rights had the legal emotion that Mongryong-Lee's administrative order suspending Hakdo-Byeon's govenor's status could be approved as an legal and exciting one. Therefore the love of Chunhyang and Mongryong-Lee implied a new legal emotion which based on the sympathy with Chunhyang's human rights consciousness, and regarded the positive law of Yi - dynasty as one behind times.

An whistle-blowing is recognition of acts of misconduct or corruption by individuals(laborers) or party which belongs to a certain organization and it refers to the act of informing to the senior organization or to the outside public agency to avoid jeopardies that could be potentially lead against benefit of the public. These whistle-blowings can be a Ansatz that improve corporation's transparency and accountability by prevention of enterprise's misconduct as well, it has been recognized as an important role for the establishment of corporate ethics, moreover, social justice. What to be treated primarily as labor law problem is arousing some controversies of the possibility that the public announcement could be whether a disciplinary punishment or not because it brings some mischievous effects for the honor and the reputation to the company which conducted the illegal actions and the action of the contrary to the social value. And futhermore, recently, the matter of compensational responsibility according to the arrangement conversion, bullying followed by the informant has been brought up. The fundamental standpoint of precedent related with the judgement of justification for the punishment as reason of the whistle-blowing ought to do the sincere duty for the labor contract which is the employees are supposed to consider the employer's profits. For that reason, if the emploee release the inside fact to the public and give any damages to employer's secret or confidence or honor, it will be a causing reasong of the disciplinary punishment, but in specific cases, the relevant and level of punishment limitation can be judged by the contents of public announcement and the truth, the purpose of the acts and details and the way of announcement. Precisely, on the assumption that there are necessity of the characteristic profit or the freedom of expression for the informant, with overall consideration whether or the basis part of the informant is true or there is a fair reason which make the informant believe is true or the purpose of informant has the public profit or the contents of the whistle-blowing are important for relevant organization or the means and the way was suitable, if the whistle-blowing are approved to be resonable, the organization are not permitted the reprimand or dismiss Futhermore, to find the solution for the issues of the disciplinary punishment and the treatment of all sorts of disadvantages, for the reason of whistle-blowing, since the protection law for public declarer which was enacted in last 2011 have the position as the general law, the purport of the equal law has to be considered sytematically and also the judicial precedent which is related to the justification of whistle-blowing are needed to be considered as well.
