Public electronic certificates, as an important means for identification, have been used as the main economic transactions, including banking, e-government, e-commerce. identification. However, damage cases of certificates have been increased by Illegally issued and by hacking practices. Also the users have a difficult in ensuring that their certificates when and where to use. Therefore, the proposed system gives the organization code for the Institutions using OCSP services in advance, the organization code embedded in extensions of OCSP request message structure when institutions ask the validation of certificate to CA(Certificate Authority). Also, OCSP server can extract the organization code from OCSP request message, confirm the institution, and record it in certificate history management table of DB. In this paper, we presented a system that could determine the certificate history check using OCSP service, public electronic certificate validation service, and implemented to prevent and cope immediately with financial incidents.

In this paper, we present a certificate management platform for performance assessment during recruitment using blockchain. Applicants are awarded certificates according to a predetermined level of progress based on their performances. All certificates are stored on a recruitment management platform that serves as an environment for storing and presenting all awarded certificates. The hashed information of all the certificates are stored in the blockchain, and once stored, the contents cannot be tampered with. Therefore, anyone can check the validity of the certificates using this blockchain. Our proposed platform will be useful for recruitment and application management, career management, and personal history maintenance.

Medical certificate is a document to demonstrate a patient's health status, made up and signed by a physician, dentist, or oriental physician who attended the patient. It serves as an evidence in many official process including civil or criminal law suit, especially for one's personal injury. The Korean legal system also acknowledges and protects the evidentiary function of medical certificate by mandating physicians etc. to issue medical certificate in good faith and only when they personally attended the patient, and by criminally punishing them when they do not comply with these legal requirements. There are some reasons, however, that medical certificates often do not reflect the true health status of the patient: When physicians attend the patient and collect information regarding the health status of the patient, their priority is and should be the most cost-effective way to meet the health needs of the patient. It does not necessarily correspond to the accurate examination of the health status of the patient. Even when the patient's report on the history of the illness or the injury seems suspicious, physicians might have to avoid disproving it because that kind of attitude might harm the rapport between the physician and the patient. All these can distort the perception of the physicians and this distortion can be reproduced in the medical certificate they made up. Some of these problems might be resolved or at least enhanced by introducing new form of medical certificate which would guide physicians to reveal the nature, factual and theoretical grounds, and the limit of their findings more accurately. Others, however, would not be able to address, because it stems from the conflict between the physician's primary duty, duty to be loyal to the patient's life and health, and his secondary duty to serve as a public or neutral witness on the health status of the patient, and when both values or duties conflict with each other, they should choose the duty to the patient sacrificing the duty to the public or the court.

Although the curator system of South Korea officially started in 2001, it has not taken root yet. Because most active curators do not have a certificate, concerned scholars are making efforts to complement and establish the curator system. Although there are currently numerous museums and art galleries that own a number of costumes and textiles in Korea, the number of curators who majored in the history of costume is very low. Despite the growing importance and the increase in costume-related exhibition than any other fields, this shortage of qualified curators resulted in the lack of specialty for the management and exhibition of past costumes. To solve this problem, there needs to be more hire for curators, in proportion to the possession and exhibition of costumes, who major in the history of costume. The history of costume must also be part of the curator test and be required even for the internship. And there must be education for curators who currently deal with costumes without having majored in the study of costume, history of costume students who want to become a costume-related curator in the future, and the general public. The contents for education must include the knowledge of artifacts, theories to enhance the management capacity, and practice in the museum.

In the paper, the actual situation of Korean organic agriculture and its development history regards to basic skills of organic farming were reported. And an education for organic farming in the universities with schools of agriculture in European countries was also reported to deliver the information on the course of organic agriculture for Korean Universities facing the problem which have a lower admission competition than previous Year. The examination for organic engineer certificate which was introduced in 2001 and the proposed government research institute, so called "Research Center of Organic Agriculture" were also shortly discussed. In the conclusion, \circled1 the establishment of "research Center of Organic Agriculture" which should by attached RDA for the systematic approach of research for organic agriculture and the test of agricultural materials using for organic farming, \circled2 department of organic agriculture in the Universities with schools of agriculture to offer next generation an opportunity to learn an organic farming parallel to conventional farming, \circled3certification body system by third party, and \circled4 full support by Korean government and scientist society for "Asian Research Network of Organic Agriculture (ARNOA)" headquartered in Korea as international research organization were strongly suggested.

In this study, we investigated the current status of the teacher education curriculum and the recruitment of general science teachers, and the ways to improve them as suggested by Professors from the Department of Science Education. Most science education departments have not required double majors in general science, and there are wide differences in the number of students who take the general science programs. There is not any department that requires science courses other than its own science major courses when students get only their own in-depth science major certificate. A few departments provide integrated science courses such as history of science, scientific creativity, integrated science, and so forth. Most professors revealed negative perceptions toward 'a compulsory requirement of double majors in general science' with other in-depth science majors such as physics, chemistry, biology, and earth sciences. The majority of professors also suggested providing elective courses in integrated science-related subjects. Regarding general science majored teacher employment, most professors did not agree with separate employment for the general science teacher, although they agreed with the necessity of the general science teaching certificate. They also suggested that preservice teachers need to take science courses other than their own specialized science majors for the in-depth science teaching certificate. Based on the results, we suggested ways to improve the teacher education curriculum and the recruitment of general science teachers.

Background: Korea has experienced rapid economic development in a very short period of time. A mixture of traditional and modern risk factors coexists and the rapid change in non-genetic factors interacts with genetic constituents. With consideration of these unique aspects of Korean society, a large-scale genomic cohort study-the Health Examinees (HEXA) Study-has been conducted to investigate epidemiologic characteristics, genomic features, and gene-environment interactions of major chronic diseases including cancer in the Korean population. Materials and Methods: Following a standardized study protocol, the subjects were prospectively recruited from 38 health examination centers and training hospitals throughout the country. An interview-based questionnaire survey was conducted to collect information on socio-demographic characteristics, medical history, medication usage, family history, lifestyle factors, diet, physical activity, and reproductive factors for women. Various biological specimens (i.e., plasma, serum, buffy coat, blood cells, genomic DNA, and urine) were collected for biorepository according to the standardized protocol. Skilled medical staff also performed physical examinations. Results: Between 2004 and 2013, a total of 167,169 subjects aged 40-69 years were recruited for the HEXA study. Participants are being followed up utilizing active and passive methods. The first wave of active follow-up began in 2012 and it will be continued until 2015. The principal purpose of passive follow-up is based on data linkages with the National Death Certificate, the National Cancer Registry, and the National Health Insurance Claim data. Conclusions: The HEXA study will render an opportunity to investigate biomarkers of early health index and the chronological changes associated with chronic diseases.
