본 연구는 고기능 자폐 스펙트럼 장애아동을 대상으로 App-기반 청자 대화기술 훈련프로그램의 효과를 검증하고 자 하였다. 연구대상은 26명의 자폐 스펙트럼 장애, 아스퍼거 증후군, 전반적 발달장애로 진단된 초등학생으로, 연령 과 IQ, SCQ, ASSQ 점수를 사용하여 중재 집단과 통제 집단으로 짝지어 분배하였다. 중재 집단은 9주 동안 교사와의 비대면 학습을 주 1회 실시하고, 가정에서도 부모 또는 아동이 앱(App)을 활용하여 대화훈련을 실시하였다. 통제 집단은 다른 특별한 프로그램에 참여하지 않았다. 그리고 훈련 전과 후에 평가자와 아동 간의 1:1 대화를 수행하여 대화 자료를 수집하고, 대화차례 주고받기와 주제 운용능력의 변화를 비교하였다. 연구 결과, 중재 집단에서 본 연구에서 개발한 청자 반응 대화훈련 프로그램의 긍정적 효과가 발견되었다. 구체적으로, 중재 집단은 청자 조건에서 적절한 청자 언어 반응이 유지되었고, 통제 집단은 적절한 청자 언어 반응이 감소하였다. 그리고 화자 조건의 대화 차례 주고받기에서는 개시율과 유지율이 증가하고, 주제 운용능력에서는 적절한 주제 개시율이 증가하고, 부적절한 주제 개시율은 감소하였다. 논의에서는 청자 반응 대화훈련 프로그램이 고기능 자폐 스펙트럼 장애아동의 대화 양상 변화에 미치는 효과를 중점적으로 논의하였다.

The primary aim of this study was to compare responsiveness of self-report by worker and therapist-scored functional capacity instrument. Self-report and therapist-scored interval-level person measures and item difficulties were compared at admission and discharge. Therapist and worker ratings were collected on 230 clients from 27 rehabilitation sites using the newly developed Occupational Rehabilitation Data Base (ORDB) functional capacity instrument. ORDB comprises several subscales measuring relevant variables of "a return-to-work model" in work-related rehabilitation clinics. The functional capacity scale deals with 10 DOT job factors. The rating scale categories were 1-severely impaired, 2-moderately impaired, 3-mildly impaired, and 4-not impaired. Only data from clients with low back pain (n=98) with complete data (both admission and discharge scores) were used for the present study. Therapists and workers completed the functional capacity instrument at admission and discharge. Rasch analysis [1-parameter item response theory model (IRT)] was applied to calibrate item difficulty and person ability measure of therapist and workers ratings. Effect sizes for therapist and self-report ratings were slightly different, .69 and .30, respectively. Therapist and worker ratings were more consistent at discharge (r=.54) than at admission (r=.32). Workers have a tendency to be more severe in their ratings (show higher item difficulties) than therapists at admission and discharge. Therapists and workers report similar magnitudes of improvement following treatment program. These findings challenge the belief that injured workers may unreliable source for monitoring therapeutic outcomes. Self-report measures have the advantage of conserving therapist time for treatment (versus evaluation). While the therapist and self-report ratings are comparable at discharge, there is less consistency at admission. Comparable therapist-worker ratings may be achieved by controlling for rating severity using IRT methodologies.

One of the important components of this administrative reform is customer satisfaction. Every public enterprises introduced the Service Charter and Korean government took Customer satisfaction as the key index of public sector performance assessment. Most public enterprises introduced customer satisfaction management in an attempt to improve the quality of customer service. The government granted high incentives to excellent business innovative enterprises and developed additional indices, which are related to CS. From now on, every Korean enterprises must embody feasible customer satisfaction management and improve the quality of customer service In this research, we proposed a quality evaluation standard model which is suitable for the public enterprise based on the Service Quality Criteria, and examined the model. A 7-Point Likert Scale was used based on the five categories within the Service Quality: responsiveness, convenience, tangibility, sympathy and reliability, we analysed the validity and causal relationship among the factors within the model.

The elderly suffer from an impaired immune function being obvious in a higher susceptibility to infections. Although the inflammatory cells are the major immunomodulatory cells, fibroblasts also secrete a variety of inflammatory cytokines and chemokines. Therefore periodontal tissue aging might playa role in development and progress of periodontitis. In this study, we investigated the effect of in vitro periodontal ligament cellular aging on the inflammatory cytokines, chemokines, and matrix metalloprotease(MMP)-2 expression induced by lipopolysaccharide(LPS) treatment. Three different cell populations were used; passages 4-5, 14-15, and 24-25 (at passage 27, more than 90% cells were replicative senescent). LPS increased the expression of interleukin(IL)-1β, IL-6, and tumor necrosis factor-α, IL-8, RANTES, and MMP-2. However, the order of induction folds were passages 14-15 > 4-5 > 24-25. While the expression level of Toll-like receptor(TLR) 4 decreased according to the increase in passage number, the level of TLR2 was highest at passages 14-15 and then decreased at passages 24-25. While the spontaneous expression of IL-8 decreased according to the increase in passage number, that of RANTES and proMMP-2 increased according to the increase in passage number. These results suggest that the aging of periodontal ligament fibroblasts differentially affect the role as immunomodulatory cells in response to periodontopathic bacteria and therefore might be another risk factor of periodontitis progression.

Perception of architectural experience is different in different culture. This paper aims to identify how the experience of architecture is understood to be different in Eastern and Western culture. The discussion is based on the idea that the Western architecture placed more emphasis on visual perception, while the Eastern, on mutual responsiveness between man and built environment. The fact that the Western culture is more visually oriented than other culture, and therefore visual aspect of architecture, too, is considered to be very important, is already widely agreed among scholars. But, then, what had been considered to be important in the architectural experience in the East? It is the degree and quality of mutual responsiveness between man and architectural environment. This fact influenced much on the making of architecture of course, and the same fact played the key role in making the Eastern architecture different from that of the West. We are so used to the way of architecture of the West, that the quality of responsiveness is unknown if not forgotten. However, it is not the quality that was useful only in traditional society of the East, but necessary in our modem period as well. The quality for responsiveness, therefore, should be rediscovered and restored as the prime value and quality of architecture in the future architecture.

DGCR8 is a RNA-binding protein working with DROSHA to produce pre-microRNA in the nucleus, while DICER does not only mature microRNA but also endogenous siRNAs in the cytoplasm. Here, we have produced Dgcr8 conditional knock-out mice using progesterone receptor (PR)-Cre (Dgcr8flox/flox; PRcre/+ mice, Dgcr8d/d) and demonstrated that canonical microRNAs dependent of DROSHA-DGCR8 complex are required for uterine development as well as female fertility in mice. Adult Dgcr8d/d females did not undergo regular reproductive cycle and produce any pups when housed with fertile males, whereas administration of exogenous gonadotropins induced normal ovulation with corpus luteal formation in these mice. Ovulated oocytes from Dgcr8d/d mice had comparable fertilization potentials and were normally developed to the blastocyst after fertilization as compared to those in control Dgcr8f/f mice. Interestingly, PR-Cre-dependent Dgcr8 deletion showed aberrant infiltration of acute inflammatory immune cells to female reproductive organs only when Dgcr8d/d mice were mated with male mice. With respect to uterine development, gross morphology, histology, and weight of Dgcr8d/d uterus were similar to those of control at 3-week-old age. However, multiple uterine abnormalities were noticeable at 4-week-old age when PR expression is significantly increased, and these deformities became severe onwards. Gland formation and myometrial layers were significantly reduced, and stromal cell compartment did not expand and became atrophic during uterine development in these mice. These results were consistent with aberrantly reduced cell proliferation in stromal cell compartments of Dgcr8d/d mice. Collectively, our results suggest that DGCR8 dependent-canonical microRNAs are essential for development and physiology of the uterus with respect to morphogenesis, proper immune modulation, reproductive cycle, and steroid hormone responsiveness in mice.
