본 논문에서는 딥러닝 기반의 주의환기 보상전략 시스템이 발달장애인의 데이터 라벨링 작업 생산성에 미치는 효과를 분석하였다. 연구 결과, 중재가 적용된 후 연구대상자 모두 자율작업 대비 작업 생산성에서 유의미한 향상이 관찰되었다. 특히 인공지능 기반의 중재가 적용되었을 때, 직무지도원 중재에 비해 상당한 향상을 보였다. 이러한 결과는 인공지능 기술이 발달장애인의 데이터 라벨링 작업 생산성 향상에 긍정적인 영향을 미칠 수 있음을 의미한다. 본 연구는 발달장애인의 데이터 라벨링 작업에 인공지능 기술을 접목한 최초의 연구이며, 발달장애인의 직업훈련과 작업 생산성 증진을 위한 딥러닝 기술의 적용 가능성을 탐색하는 데 중요한 시사점을 제공하리라 본다. This paper investigates the effect of a deep learning-based system on data labeling task productivity by individuals with developmental disabilities. It was found that interventions, particularly those using AI, significantly improved productivity compared to self-serving task. AI interventions were notably more effective than job coach-led approaches. This research underscores the positive role of AI in enhancing task efficiency for those with developmental disabilities. This study is the first to apply AI technology to the data labeling tasks of individuals with developmental disabilities and highlighting deep learning's potential in vocational training and productivity enhancement for this group.

This paper aims to examine the nature of the inow of cultural elementsinto the Korean Peninsula during the Bronze Age, namely the introductionof elements from the Machengzi Culture of the Taizi River basin, located inthe northeastern area of China, to the Nam River and coastal areas of theGyeongnam region in Korea. Although connections between both regions have been recognized throughpottery decorated with broad ower petal designs, interpretation has not beeneasy due to the sparse ndings of excavated examples of this pottery in theMachengzi Culture sphere, in addition to the absence of other related culturalfactors and the distance between the two regions. This paper presents newarchaeological material in order to establish connections between the tworegions. The new material comprises new ndings of pottery with broad owerpetal design, pottery which has a single or double cross patterns decorating thearea in between the vessel neck and shoulder, double-rimmed bowls with aninner gallery, and tombs dating to the early part of the Bronze Age which werebased on pit burials, all of which have been conrmed in the upper reaches ofthe Taizi River. These elements are not only commonly found in both regions,they also appear exclusively in these two regions. Based on these facts, it is established that the cultural elements of theMachengzi Culture, which came from the Taizi River basin, were introducedinto the Gyeongnam region from the end of the rst half of the Early BronzeAge to the latter part of the Early Bronze Age (around 1000 BCE). Because thesematerials are not found in any of the other regions of the Korean Peninsula, they are seen to have come from the Taizi River basin into the Nam River basin. This movement of cultural factors is difcult to understand without assuming themovement of people. Consequently, it can be assumed that the culture inowfrom the Taizi River basin directly and unilaterally affected the Gyeongnamregion at the time. Only some of the cultural elements of the Machengzi Culturewere brought into from the area of origin, and they are considered to have beenfused into the unique local culture as phatic factors. The reasons behind such an event of long distance migration is a difcultissue to deal with specically but a huge change can be identied as havingtaken place in the Korean Peninsula and the northeastern area of China at thetime. This can be seen to imply that a great impetus for change was presentat the time throughout the entire area spanning from China to the Korean Peninsula.

Abstract The PZT thin film was deposited by usin. RF magnetron sputtering with PZT(52/48) target. The formation of perovskite structure PZT thin film started at 55$0^{\circ}C$ on Si substrate. The AES results showed an oxide layer formed at the between Si and PZT film during the annealing. And, Ti$O_2$ layer appeared at the between TiN and PZT film for the annealing. But, the perovskite phase PZT film was formed after the annealing on the Si$O_2$/Si substarte. The ratio in PZT film was constant across the asdeposited PZT film, but, Pb have diffused into the Si substrate and Si have out-diffused into PZT layer during the post annealing at 75$0^{\circ}C$. The dielectric constants of PZT film indicated about 1300( thickness: 1500$\AA$, at 10KHz) but, the cracks were appeared to surface for annealing. RF magnetrom sputtering으로 52/48 PZT target을 사용하여 PZT thin film을 증착시킨후, furnace annealing을 실시하여 Si 기판에서는 55$0^{\circ}C$에서부터 안정상인 peroskite구조가 형성되었다. Si기판위에서는 후속열처리시 계면에 상당한 산화막층이 형성되었으며 TiN 기판위에서는 후속열처리시 TiN층은 사라지고 Ti$O_2$층이 형성되었다. Si$O_2$기판에서는 후속열처리후에도 안정한 PZT film을 형성시킬 수 있었다. As-depo.시에는 PZT film의 조성비가 균일하게 유지되었으나 75$0^{\circ}C$후속열 처리시에는 상당량의 Pb가 Si기판으로 diffusion하였으며 Si도 out-diffusion하였다. 전기적 특성은 10KHz에서 C-V를 측정결과 약 1300정도의유전상수 값이 나왔으나 후속열처리시 표면에 crack이 발생하였다.

Recently, there is a growing interest in efficient biomass pretreatment and saccharification processes to produce biofuels and biochemicals from renewable non-food biomass resources. In this study, glucose was produced from cellulose by immobilizing cellulase enzyme on chitosan beads which was reported to have high pH and temperature stability. The immobilized amounts of cellulase on chitosan beads linearly increased with increasing the concentrations of cellulase solution. The glucose production increased to 7.2 g/L from 1% carboxymethyl cellulose (CMC) substrate when immobilized at 20% cellulase solution. The maximum specific activity was 0.37 unit/mg protein when immobilized at 8% cellulase solution. At pH 7 and 37℃, the optimum reaction composition was 0.5 g beads/L from 1% CMC substrate. At this condition, the conversion to glucose completed at ca. 20 min.
