The purpose of this study is to analyze the employment trends of autonomous automobile industry which is related to the 4th Industrial Revolution. Previously, big data of the employment trends were divided into skill field and task field. As a result, if a company was employed in the field of skill field, it was required to have talent in which personality traits and innovation traits were prominent. Second, if the task field is a production worker, it is desirable to have talented person with outstanding personality traits. In addition, if the task field is management, it has been confirmed that communication qualities require outstanding talent. The results of this study suggest that it is possible to use the data as a basic data for finding an effective employment strategy by identifying the characteristics of the talented person and considering the suitability of the tendency of hiring.

The purpose of this study is to compare and analyze the differences in employment trends between enterprises and job seekers related to the 4th Industrial Revolution, focusing on the 11 elements of recruitment process. As a method of analysis, a methodology suitable for the convergence research methodology was used by mixing social network analysis and variance analysis, and significant results were derived. First, while large enterprises emphasized organizational culture and job analysis, small enterprises emphasized an interview from the perspective of practitioners. Second, in both manufacturing and service industries, enterprises emphasized interviews and documents, but job seekers emphasized job analysis. Third, the proportion of the recruitment process was found to be greater in the manufacturing industry than in the service industry. Fourth, it was found that enterprises accounted for a larger proportion of the recruitment process than job seekers. This showed an interaction effect between the subject and the industry sector. Therefore, the evaluation of the recruitment process between enterprises and job seekers was found to be very different.

대형구조물 제작 시에는 세라믹백킹재 등 백킹재를 이용한 편면용접법이 많이 채용되고 있다. 이처럼 백가우징이 적용되지 않는 편면용접법으로 용접 시공 시, 표면부에 비해 루트부의 충격성능이 열화되는 경향이 있다. 본 연구에서는 세라믹백킹재를 채용한 편면용접법의 루트부의 저온 충격성능을 확보할 수 있는 용착금속의 Ni 함량에 대해 고찰하고자 한다.

In 1997, Lavagnino defined four stages of technology trends in libraries; but, he left a question about the fifth stage. Based on literature review, the following; Web technology, open source application, library consortia, digitization, wireless, and social media are the main trends in the fifth stage. Analyzing the job advertisements (ads) dating from 2006 to 2010 in systems librarianship, the analysis showed that there are three patterns. The first pattern is that the title of 'system librarian' is no longer specific to managing only the ILS at many libraries. The second pattern - network management skills - is not highly required in the job ads. And the last pattern - especially academic institutions which have archive or special collection departments - was looking for a systems librarian. In addition, Web technology has evolved as the most required skill according to the advertisements, as well as inter-personal skills in a team environment.

Postoperative autotransfusion is known as an effective method for blood conservation. We tried to examine whether the autotransfusion of shed mediastinal blood in patients with unstable angina would be valuable for reducing postoperative homologous transfusion by observing the hourly tendency of bleeding and transfusion. Between August and October, 1997, 26 patients with unstable angina underwent coronary arterial bypass surgery by a single surgeon at Asan Medical Center. In retrospective analysis, we found 90% of the patients received homologous transfusions and 85% of them were in the intensive care unit at the same day after operation. In many patients, the cause of transfusion was not anemia but volume replacement. Mean bleeding through the chest tubes was 340 cc for the first 5 hours and 69%(18 pts) showed more than 200 cc of bleeding, the amount generally considered as a initiating point for autotransfusion. Despite the adoption of multiple methods for blood conservation, 90% of the patients needed homologous transfusion. Moreover, many of them had received unnecessary transfusions. We conclude that some kind of blood for transfusion is needed during the immediate postoperative period, and the adoption of postoperative autotransfusion may help in reducing homologous transfusion.

연료소비율의 향상은 점차 감소되어 가는 경향에 있다. 그 원인은 3원촉매변환기 채용에 의한 이론공기연료비의 사용, 기관의 연소개선이 발전하여 고압축비화에 의한 연료소비율 향상이 더 이상 어렵게 되었다는 점을 들 수 있다. 한편, 고압축비화의 역효과로는 연소실내 최고압력이 증가하여 각부의 강도나 기관 소음의 문제가 대두된다. 이들 역효과를 타파하여 충분한 연료 소비 향상을 얻을 수 있는 수단이 단기적인 과제가 될 것이다. 전자제어, 희박연소, 마찰저감 등 통상의 엔진의 개량에 대한 노력이 계속될 것이다.

전통적으로 정보통신산업에서는 요금규제방식으로 최종 서비스 시장에 대해서는 보수율규제, 중간재 시장에 대해서는 공통원가 배분방식을 채용하는 것이 일반적 경향이었다. 그러나 최근 선진국에서는 전자의 시장에 대해서는 가격상한규제, 후자의 시장에 대해서는 장기증분 원가방식으로 옮겨가고 있다. 본 고에서는 이들 최종 서비스 가격에 대한 두 가지 규제방식과 접속료에 대한 두 가지 규제방식을 짝 짓기 하여 4개의 규제조합을 만들고, 각 규제조합이 정부의 규제목표에 어느 정도 기여하는지를 논의하고 우리 나라의 현실에 부합되는 규제조합을 제시하였다.

전력수요의 증대에 따라 송전전압이 점차 높아지는 것은 세계적 경향이며 우리 계통도 전력수요의 계속적 성장과 발전기단위용량의 대형화로 지역간 격통전력은 증가추세에 있어서 현재 154KV보다 높은 345KV대용량 송전전압을 채택하게 되었다. 이 345KV계통은 전력계통의 골격을 이루고 있으므로 공급신뢰도가 높아야겠으며 만일 고장이 발생하였을 때 고장제법의 지연이나 실패를 할 경우, 그 영향이 전계통에 파급하여 대정전을 야기할 가능성이 높으므로 계통구성의 강화와 더불어 보호계전장치도 종래보다 한층 높은 성능과 동작신뢰도를 확보해야 한다. 또 345KV변전소는 3/2CB모선이나 다단권변압기등 종래의 계통에는 없는 새로운 설비와 회로구성을 채용하기 때문에 보호계전방식도 이들과 조화된 방식으로 해야 한다.

This study comparatively analyzed the differences in the talented human resources perceived by enterprises and job seekers in terms of recruitment trends of companies related to the 4th Industrial Revolution, focusing on 16 factors. The analysis data was collected from enterprises and job seekers related to the 4th Industrial Revolution, and the analysis method was applied to a convergence research methodology that mixes social network analysis and variance analysis using big data type. As a result, several things were verified. First, large enterprises emphasized communication, and small enterprises emphasized competency and confidence. Second, in the manufacturing industry, enterprises emphasized confidence and competence, and job seekers emphasized spec and passion. Third, in the service industry, enterprises emphasized personality and competence, and job seekers emphasized spec and global. Fourth, there was a big difference in talented human resources between enterprises and job seekers according to manufacturing and service industries. Based on these results, we discussed the opening of employment information for enterprises to reduce the recognition mismatch in the talented human resources.

In the development and mass production of polymers, there are many uncontrollable variables. Even small changes in chemical composition, structure, and processing conditions can lead to large variations in properties. Therefore, Traditional linear modeling techniques that assume a general environment often produce significant errors when applied to field data. In this study, we propose a new modeling method (GPR-SEM) that combines Structural Equation Modeling (SEM) and Gaussian Process Regression (GPR) to study the Friction-Coefficient and Flexural-Strength properties of Polyacetal resin, an engineering plastic, in order to meet the recent trend of using plastics in industrial drive components. And we also consider the possibility of using it for materials modeling with nonlinearity.
