아웃소싱의 새로운 형태로 등장한 ASP 서비스는 저렴한 비용, 낮은 위험부담 등의 장점 때문에 소기업이나 신생기업에 유용한 정보화 방안이 될 수 있다. 그러나 ASP는 그 중요성에도 불구하고 이에 대한 학문적 연구는 그렇게 많지 않은 실정이며, 지금까지 아웃소싱에 대한 연구 또한 대기업을 주 대상으로 하고 있다. 본 연구의 목적은 ASP 서비스의 주 사용자 입장에서 국내 소기업과 관련한 주요 환경변수가 ASP 서비스의 활용유형에 미치는 영향을 살펴보고 그 활용유형별로 서비스 만족도와 기업성과간의 관계를 살펴보는데 있다. 실증분석결과, 본 연구에서 주요 환경변수로 고려된 기업규모는 소기업의 정보화 필요성 인식도에 영향을 미치고 정보화 필요성 인식도는 교육시간 및 사용기간에 영향을 미치는 것으로 밝혀졌다. 또한, 기업규모, 정보화 필요성 인식도, 교육시간은 소기업의 ASP 서비스 활용유형에 영향을 미치는 반면에 사용기간은 소기업의 ASP 서비스 활용유형에 영향을 미치지 않는 것으로 밝혀졌다. 마지막으로 본 연구에서는 소기업의 ASP 서비스 활용유형은 기업성과 및 사용자 만족도에 영향을 미치고 ASP 서비스에 대한 사용자 만족도는 기업성과에 영향을 미친다는 점을 검증하였다.

Purpose: In the current era of rapid development of the information and communication technologies (ICT) sector, the formation of an effective regulatory approach is important. There are some methodological shortcomings and difficulties in the approach system of international organizations that assesses the level of application of ICT in various areas in terms of quantity and quality. The basic element of economic growth differs according to the economic conditions prevailing in the period and the country. While the agricultural sector plays an active role in economic growth or development in an underdeveloped country, in a developed country, capital-intensive and even technology-intensive production is the main element of economic growth. From this point of view, the contribution of information and communication technologies (ICT) to Azerbaijan's socio-economy for the period between 2010-2020 will be examined. Research design and methodology: The unit root test and Granger causality test were applied by taking the CDPPC per Capita, Employment, and Unemployment Rate from the social-o-economic data as the dependent variable, fixed and mobile phone usage and internet usage as the independent variables. The principal results: According to the results obtained; It has been determined that the use of ICT positively affects the socio-economic economic situation.

마이크로프로세서의 발전과 함께 멀티코어 시스템은 점차 보편화 되어가고 있다. 이러한 하드웨어 성능향상 패러다임의 변화로 인해 소프트웨어의 성능향상을 위해서는 기존의 싱글 스레드 어플리케이션들을 멀티 스레드 어플리케이션들로 교체하는 과정이 필수적이다. 멀티 스레드 어플리케이션 개발의 복잡성 때문에, 성능모니터링 도구는 어플리케이션의 성능 최적화를 지원하기에 유용한 도구로 사용된다. 기존의 성능모니터링 도구는 사용의 편의성이나 실시간성의 지원보다는 성능 측정 자체에 초점이 맞춰져 있다. 실시간 성능 모니터는 멀티 스레드 어플리케이션이 수행하는 동안 나타나는 문제점을 파악하는 것 뿐 아니라 실시간으로 어플리케이션의 동작 상태를 개발자가 확인 할 수 있기 때문에 단순한 성능 지표들만으로 문제점의 원인을 찾아내야하는 비 실시간 성능 모니터에 비해 효과적인 도구로 사용될 수 있다. 본 논문에서는 멀티코어 시스템을 위한 실시간 성능모니터링 도구인 RMPM(Real-time Multi-core Performance Monitor)를 제안하고 성능 측정 주기로 인한 오버헤드와 정확성 사이의 관계를 비교하여 최적의 측정 주기를 결정하였다. 제안한 성능모니터는 전체시스템의 CPU 사용량, 메모리 사용량, 네트워크 사용량 뿐아니라 시스템의 코어별, 어플리케이션의 스레드별 부하 분산상태를 나타낼 수 있다.

Objectives: This study evaluated alterations in neuronal conductivity related to calcium silicate cements (CSCs) by investigating compound action potentials (cAPs) in rat sciatic nerves. Materials and Methods: Sciatic nerves were placed in a Tyrode bath and cAPs were recorded before, during, and after the application of test materials for 60-minute control, application, and recovery measurements, respectively. Freshly prepared ProRoot MTA, MTA Angelus, Biodentine, Endosequence RRM-Putty, BioAggregate, and RetroMTA were directly applied onto the nerves. Biopac LabPro version 3.7 was used to record and analyze cAPs. The data were statistically analyzed. Results: None of the CSCs totally blocked cAPs. RetroMTA, Biodentine, and MTA Angelus caused no significant alteration in cAPs (p > 0.05). Significantly lower cAPs were observed in recovery measurements for BioAggregate than in the control condition (p < 0.05). ProRoot MTA significantly but transiently reduced cAPs in the application period compared to the control period (p < 0.05). Endosequence RRM-Putty significantly reduced cAPs. Conclusions: Various CSCs may alter cAPs to some extent, but none of the CSCs irreversibly blocked them. The usage of fast-setting CSCs during apexification or regeneration of immature teeth seems safer than slow-setting CSCs due to their more favorable neuronal effects.

In Korean housing designs reflect uniqueness as a result of the influence of regional and atmospheric factors. In this regard, the early use of the hot floor (ondol) system is of special significance. This system is still in use today, not only for house-heating purposes in the homes of commoners, but also for cooking in the kitchen. The present study represents an investigation of the ondol structure since its earliest known usage. Methodology involves a documentary examination of the system. In point of time, this begins with the system's earliest usage and proceeds chronnologically down to the end of the Yi Dynasty. Research indicates that something very much like the ondol system appeared in the early tribal society of Mahan and its usage continued in the state of Koguryo (during the Three Kingdoms Period) in the homes of the poor. This unique system which had its origin in cold northern areas was utilized on a much broader basis during the Koryo Dynasty. Coming down to the Yi Dynasty it found acceptance and application in all parts of the peninsula. Variations in major component parts of the structure, such as the fuel hole, the flue, the draft , and the chimney, normally reflect regional dissimilarities. It is perhaps most significant that here-in contrast to other devices we have a system that serves concurrently for both heating and cooking purposes.

Objectives This study aimed to investigate the status of Chuna manual therapy(CMT) usage before and after COVID-19 social distancing measures. Methods This study utilized Health Insurance data from April 2019 to May 2023. Quarterly data were collected for Simple Chuna (code 40710), Complex Chuna (code 40720;50% patient expense), Complex Chuna (code 40721;80% patient expense), and Special Chuna (code 40730). Results During the period covered by health insurance, the number of CMT patients was 8,315,838, with 19,332,786 instances of CMT, and a total cost of 544,651,407 won. Due to COVID-19, the application of CMT decreased in the first quarter of 2020, but recovered from 2021, showing an increase in usage by the first quarter of 2023. The decline in the use of all medical institutions in the fourth quarter is believed to be due to restrictions on health insurance coverage for CMT. Conclusions Further research on CMT health insurance is necessary. This research should inform discussions on policies aimed at expanding health insurance coverage for CMT.

Objectives : This study examined the possibility of therapeutic application of natural pigments in the Joseon Period other than aesthetic purposes. Methods : The medicinal properties of natural pigments as written in the texts Sangayorok, Gyuhapchongseo, Imwongyeongjeji were searched and analyzed in the texts Bencaogangmu, Encyclopedia of Eastern Medicine, and the Encyclopedia of Chinese Medicinals focusing on their Qi, flavor, effects and application. Of the conditions they treated, we examined whether they treated skin conditions using external application. The Korean Medical effects of these pigments were examined based on the content of the skin chapter of the Donguibogam. Results : We were able to extract 47 kinds of natural pigments, most of which had cold nature and bitter tasting properties. In addition, most of the pigments had the effect of treating skin conditions, illnesses due to micro-organisms, and of detoxifying. Conclusions : After consideration of medicinal properties and effects of the herbs that were used as pigments in the Joseon period, it could be concluded that as these herbs not only function as pigments but also hold properties that prevent skin conditions, their therapeutic functions could have been considered when using them as pigments.
