Blockchain technology has the potential to revolutionize trust models and business processes in a variety of industries. However, it is considered to be the initial stage of the system that pursues autonomy rather than efficiency, and it is necessary to monitor and inspect the distributed ledger technology from the price and introduction time as compared with the existing relational DB transaction technology. However, domestic and foreign private sectors have already been activated by applying block-chain technology in the national domain, and the block chain is devoid of doubt that it is an exaggerated technology, characterized by the invariance of the record, transparency, and autonomous execution of business rules. It has begun to be utilized in history, identity, certification and auditing in the financial industry as well as various industries. In this paper, we analyze the problems such as security weakness, insufficient regulatory environment, technical consensus and lack of common standard. In addition, the business sense and possibility of the block chain technology is expected to be the innovation of the industrial ecosystem by entering into the reality system from the concept through monitoring the actual introduction performance in the field of copyright, logistics, health care and environment.

숨가쁘게 달려오던 한국사회는 문득 21세기의 문턱 앞에 서 있다. 지난 한 세기는 한국 뿐만 아니라 세계건축계에도 많은 변화와 발전이 있었다. 이렇다 할 준비없이 우리가 맞이하는 21세기는 정보와 문화가 주도할 것으로 예상된다. 새로운 밀레니엄에 대한 기대와 세기적 전환시대를 맞는 현 시점에서 그동안 한국건축은 급격한 경제성장과 아울러 새로운 서구적 건축의 유입으로 인해 우리는 건축문화에 대한 관심을 기울일 시간도 없이 양적인 성장을 계속해 왔다. 외래건축의 유입으로 인해 한국건축이 겪었던 문화적 충격은 단순한 문화적 충돌이 아니라 기존 도시구조의 대대적인 변형과 파괴에 시달려야 했으며, 이로 인한 불균형한 개발은 급조된 건축물을 생산하는 결과를 초래하게 되었고, 이와 함께 우리 건축문화의 모습은 기형적인 도시환경의 모습으로 대체되었다. 이러한 상황에서 다가올 21세기는 WTO세계무역기구의 발전과 더불어 국가간의 개방정책이 불가피하게 이루어지고 있으며, 이에 따라 사회 전분야에 걸쳐 새로운 시도는 빠르게 움직이고 있다. 건축분야 역시 문호 개방원칙에 따라 국가간 건축사자격 상호인증에 대한 각국간의 심도있는 논의와 그에 따른 교육 및 시험수준, 경력의 요구조건, 제반규제사항 등 각국의 상호 차이점에 대한 구체적인 협의가 올해 열린 UIA(세계건축사연맹) 북경 총회에서 승인되어 표준안이 공포되었다. 이에 따라 우리나라도 건축사자격 상호인증에 대한 대책 마련을 위해 공청회개최 등을 통해 본격적인 논의가 이루어지고 있다. 이제 우리 건축계도 새로운 세기를 맞는 시점에 서 있다. 이러한 상황에서 한국건축계는 급변하는 세계속에 우리의 건축문화를 계승 발전해야 할 과제를 안고 있다. 이에 본지에서는 밀레니엄 특집으로 '21세기 한국건축의 비전'이란 주제로 한국건축의 새천년의 미래를 내다보고 이를 통해 우리 건축이 담고 있는 현실과 문제의 실마리를 풀 수 있는 계기를 마련하고자 이번 특집이 계획되었으며, 또한 한국건축이 나아갈 바람직한 방향을 짚어 봄으로써 한국건축의 활로를 모색하고 세기적 전환시대를 맞는 우리 건축의 미래지향적 자료로 활용되었으면 한다.

This study aims to investigate and practically examine the effect of environmental qualifications based on the theoretical background on the area. First, the economic effect of the acquisition of the qualifications was to be studied from the viewpoints of individuals and from an actual analysis on it, its effect was to be proved. Second, its non-economic effect was to be proved from the same way as the first analysis. On the basis of theoretical background, a study model was formulated in a way that the effect of qualifications in individuals side was divided into an economic effect (wage, employment, promotion, job-switching) and non-economic effect (self-development, self-efficiency, satisfaction on the job, ability to cope with the advancement of technology, job performance, signal effect, the settlement of uneasiness at unemployment). Then, survey was carried out with questions designed in accordance with this model. The hypotheses were proved as the following. First, for hypothesis 1(Environmental qualifications will bring up positive impacts on an individuals economic effect), environmental qualifications was shown to have positive impacts on wage, job-switching in personal economic effect. But, no personal economic effect appeared for employment and promotion. Second, for hypothesis 2(Environmental qualifications will bring up positive impacts on an individuals non-economic effect), environmental qualifications appeared to have positive impacts on self-efficiency, ability to cope with the advancement of technology, job performance and signal effect. Besides, no impact was shown in satisfaction on the job and the settlement of uneasiness at unemployment and self-development.

Today, record management has become more important in management as records generated from administrative work and data production have increased significantly, and the development of information and communication technology, the working environment, and the size and various functions of the government have expanded. It is explained as an example in connection with the concept of public records with the characteristics of big data and big data characteristics. Social, Technological, Economical, Environmental and Political (STEEP) analysis was conducted to examine such areas according to the big data generation environment. The appropriateness and necessity of applying big data technology in the field of public record management were identified, and the top priority applicable framework for public record management work was schematized, and business implications were presented. First, a new organization, additional research, and attempts are needed to apply big data analysis technology to public record management procedures and standards and to record management experts. Second, it is necessary to train record management specialists with "big data analysis qualifications" related to integrated thinking so that unstructured and hidden patterns can be found in a large amount of data. Third, after self-learning by combining big data technology and artificial intelligence in the field of public records, the context should be analyzed, and the social phenomena and environment of public institutions should be analyzed and predicted.

This study was performed to derive a new business administration framework based on the service philosophy established in the previous research. We proposed a business administration system that reflects the changes of modern economic society and solves problems of existing business administration. The problem of the existing business administration is analyzed by analyzing the essential problems of business administration as a discipline and the practical problems of current business administration. New management theory must have a status as an intrinsic discipline, so it must meet the common principles of human society. The principles of universe and the life principle of mankind, which are the environment in which human beings live, were reflected. As a result of deriving these common principles, qualification requirements as the intrinsic disciplines of business administration can be defined. The new business administration discipline is constructed in three fields. Business philosophy, a theory of manager, and business administration skills are three sub-fields of new business administration. We define the detailed structure of each field of new business administration and present the main research topics. In the future, further research is needed to deepen the culture of essence in business administration, and it is necessary to study the construction of the new business administration theory in detailed field.

This study suggests improvements for the effective operation of refresher courses by reviewing the target groups for each refresher course, the contents of these courses, the estimated number of delegates for each refresher course and the operation methods of training institutes overseas. Approximately 37,000 people need to complete the maritime safety refresher courses every 5 years. For the convenience of seafarers, it is necessary to reduce the land training by activating and standardizing on-board training recognized by the STCW Convention and promote investment in the training sector to continuously improve the seafarer safety training. It is also necessary to examine ways to improve the difference between the curriculums of the domestic refresher courses and the one of the STCW Convention. In addition, investments in the development of safety training facilities and virtual reality training programs are required in order to provide an environment where seafarers can take safety refresher courses in a timely manner.

Modern society is developing rapidly and technologies that provide convenience in living are developing day by day. On the other hand, the development of cyber attacks that threaten cybersecurity is developing faster, and it still adversely affects the industrial environment, and industrial damage is steadily occurring every year. Industrial security is an activity that safely protects major assets or technologies of companies and organizations from these attacks. Therefore, it is a situation that requires professional manpower for security. Currently, the manpower situation for security is staffed, but knowledge of the understanding and concept of industrial security jobs is insufficient. In other words, there is a lack of professional manpower for industrial security. It is the NCS that came out to solve this problem. NCS is the state standardized ability (knowledge, attitude, skills, etc.) necessary to perform duties in the industrial field. NCS can systematically design the curriculum using NCS as well as help in hiring personnel, and NCS can be applied to the national qualification system. However, in the field of industrial security, NCS has not yet been developed and is still having difficulties in hiring personnel and curriculum. Although the NCS system in the field of industrial security has not been developed, this paper proposes the industrial security NCS to solve the problem of hiring professionals later and to help the field of industrial security NCS to be established later.
