Online recruitment websites discuss job demands in various fields, and job postings contain detailed job specifications. Analyzing this text can elucidate the features that determine job salaries. Text embedding models can learn the contextual information in a text, and explainable artificial intelligence frameworks can be used to examine in detail how text features contribute to the models' outputs. We collected 733,625 job postings using the WORKNET API and classified them into low, mid, and high-range salary groups. A text embedding model that predicts job salaries based on the text in job postings was trained with the collected data. Then, we applied the SHapley Additive exPlanations (SHAP) framework to the trained model and discovered the significant words that determine each salary class. Several limitations and remaining words are also discussed.

As a result of the project 'Development of core technology for open LBS', we developed several solutions such as personal navigation system, mobile game, and emergency system. In this paper, we explain the approach and architecture of these solutions and consider their meaning on spatial information bases and expectation in the future computing environments. The final goal of this suggested solution is to test the efficiency of our open LBS system and verify the applicability and usability in real application environments. Our approaches will be headed to the future ubiquitous computing environments.

This study was to predict through the trend analysis, one of the forecast technique, the future of library End Information center. In order to do that literature reviews, analysis of library's home page and specialist interview were conducted. As a result, It appeared that based on the trend analysis to predict the middle future(after 5-10 years) of library and information center. The results of this study are as follows. The first, the future information environment is represented by mobile and ubiquitous. Through this, anytime, anywhere, any device, we can be taken any media. The second, the problems of future library are technical, economic, social, ethical and legal problem. The third, unreliable factors come out in time lag, the supply speed of terminals, library services, copyrights and so on. The fourth, the future library is expanded through wireless terminal information access and use, development of mobile technique, universal ubiquitous environment and electronic information's use are extended.

Objectives : We studied the ISP(information strategy plan) of oasis spanning 5 years. From this study we aimed at total road map to upgrade the service systematically and to carry out the related projects. If we do it as road map, oasis will be the core infra service contributing to the improvement of TKM(traditional korean medicine) research capability. Methods : We carried out 3 step ISP method composed of environmental analysis, current status analysis and future plan. We used paper, report and trend analysis document as base materials and did the survey to get opinions from users and TKM experts. We limited this study to drawing the conceptual design of oasis. Results : From environmental analysis we knew that China and USA built up the largest TM databases. We did the survey to get the activation ways of oasis. And we did the benchmarking on the advanced services through current status analysis. Finally we determined 'maximize the research value based the open TKM knowledge infra' as oasis' vision. And we designed oasis' future system which is composed of service layer, application layer and contents layer. Conclusion : First TKM related documents, research materials, researcher information and standards are merged to elevate the TKM information level. Concretely large scale TKM information infra project such as TKM information classification code development, TKM library network building and CAM research information offering are carried out at the same time.

Objectives: Current information & communication technology is advancing very rapidly and the ripple effects are spreading all over society traditional Korean medicine (TKM) is no exception. We draw up afuture plan and target system's architecture of KIOM's OASIS to follow the information change and reinforce the supporting infra for TKM research. Methods: First, we analyzed the information circumstances of western and eastern medicine, both overseas and domestic, especially investigating the detailed changes domestically. Second, we grasped the present conditions of OASIS and compared it with other information portals. Finally, we drew a future plan and system architecture from the analysis results. Results: First, the information status of western medicine is much more advanced than TKM's, and overseas information circumstances are likewise more developed than domestics. Second, we found that OASIS is performing the central research infra role well in TKM. Finally we designed an information system architecture which is composed of an infra layer, an application layer and a service layer. Conclusion: We must integrate information materials such as literature, research manpower, facilities and standards to make TKM's knowledge portal successful. In detail, we have to make TKM's information classification code, build up the electronic TKM library and offer complementary and alternative medicine (CAM) trends.

In this paper, a VHF band conformal antenna for UAV mounting was developed. The proposed antenna was designed as an shape-adaptive structure by minimizing the antenna height to be advantageous in RCS reduction performance. As for the antenna radiator, the outer radiator was arranged around the inner radiator to apply the CRLH zeroth-order resonance structure. With this structure, the height of the antenna was minimized, and it was reduced by about 70 % compared to the existing blade antenna. In addition, for impedance matching, the intermediate frequency bandwidth of the VHF band was improved through the sleeve pin of the inner radiator, and the low frequency bandwidth of the VHF band was improved by applying an EMI shielding gasket to the shorting pin of the outer radiator. The proposed antenna was manufactured and measured to verify the performance of the device and the performance after UAV mounting. As a result, the standard was satisfied for the operating frequency.

데이터 스트림 환경에서 연속 질의를 처리하기 위한 데이터 스트림 처리 시스템이 개발되었다. 데이터 스트림 처리 시스템에서 질의를 처리하는 태스크에 과도한 데이터가 발생할 경우 일반적으로 데이터 스트림을 선별적으로 버리는 load shedding 방법을 이용하지만 이러한 방법은 처리 결과의 정확도가 저하될 수 있다. 따라서, 본 논문은 이를 해결하는 방법으로 분산 데이터 스트림 처리 시스템에서 데이터 스트림 분할을 통한 데이터 스트림 연속 처리 태스크의 병렬 처리 방법을 제시한다. 이를 위해 분산 데이터 스트림을 처리하기 위한 기준을 제시 및 데이터 분할 방법에 대해서 언급한다.
