음성인식 시스템이 있어서 현재 가장 널리 사용되고 있는 Hidden Markov Model(HMM)은 확률 모델을 기반한 것으로 데이터에 대한 통계처리를 학습과정으로 하고 있다. 한국어 연속 숫자음에 대한 음성인식은 고립 숫자음 인식과는 달리 충분한 학습데이터만으로는 만족할 만한 결과를 가져오지 못한다. 이 논문에서는 연속 숫자음 음성인식에 잇어서 비슷하게 발음되는 숫자음과 같은 숫자에 대해 다양하게 발음되는 숫자음에 대해 HMM의 한계를 제시하고 그 해결채으로 Discriminant 학습의 적용방법을 제시한다. 연속 숫자음의 인식 시스템을 구현하는 데 있어서 인식률 낮은 부분에 Discriminant 학습을 적용하여 인식률을 대폭 향상시킨 실험결과를 제시한다.

In our previous studies, it was found that activities of maternal peripheral lymphocytes and thymocytes were depressed during the implantation period in rats and rabbits. This study was therefore attempted to clarify further this immunosuppression locally by determining lymphocyte response in lymph nodes draining the uterus (DLN) and to elucidate the mechanism by which prostaglandin E (PGE) modulates immune response during the implantation process in rats. As compared with non-pregnant rats, the response of DLN lymphocytes to concanavalin A (Con A) was depressed during the implantation period in 100% of rats studied. The activity of DLN lymphocytes depressed on day 8 of pregnancy was, however, restored partially by the treatment of indomethacin (ID), indicating that prostaglandin (PG) might be one of factors responsible for immunomodulation during the process of implantation. DLN lymphocyte activity in non-pregnant rats was suppressed if PGE was pre-treated prior to Con A and this suppression was partially restored by the treatment of ID. Furthermore, DLN lymphocytes pre-treated with PGE produced PGE in vitro and this PGE production was blocked by the treatment of ID, suggesting that PGE induced PGE-producing cells. However, the pretreatment of estradiol, progesterone, and hCG at doses enough to suppress lymphocyte activity was ineffective in inducing PGE-producing cells. From these results, it is suggested that PGE induces PGE-producing suppressor cells, thereby increasing PGE concentration and PGE in turn depresses maternal local immune response as well as systemic immune response during the implantation period in rats.

The black soldier fly larvae are able to decompose various organic wastes such as livestock manures and food wastes. We tested whether the quality of the insect derived compost, i.e. larval feces, was comparable to that of a commercial fertilizer. Chemical analysis of Hermetia. illucens compost was suitable as a fertilizer. When the kidney bean (Phaseolus vulgaris L.) was raised on the culture soil treated with the H. illucens compost, the growth of leaf area, total dry weight and leaf dry weight increased significantly. The H. illucens compost is thought to act as an increasing factor of RGR (relative growth rate) from the beginning of growth and also had a great effect on the relative growth rate throughout the late stage of growth. There is high statistical significance between NAR (net assimilation rate) and RGR (relative growth rate), but no significance between RGR and LAR (leaf assimilation rate) of the treatments. In addition, the treatment of H. illucens compost promoted the thickness of leaves from the beginning of growth and the tendency of thickening leaves from the beginning of growth and the effect continued throughout the late period of growth. When mixed with 50% of H. illucens compost rather than 25%, it showed the greater effect on the plant growth.

Objective : The purpose of this study is to find out whether group approach of sensory integration (SI) enhances sensory processing, fine motor function, and social skill for the children with sensory integration disorders. Method : Three children with problems related in sensory integration had got received 21 intervention sessions. We evaluated children with sensory profile(SP), social maturity test, Korean-developmental test of visual perception(K-DTVP), Bruininks-Oseretsky Test of Motor Proficiency(BOTMP) before-and after intervention. The statistical significance of data is tested by the Wilcoxon matched-pair signed rank test. Results : All data of post-intervention did not show any statistically significant differences; SP, social maturity test, K-DTVP, BOTMP. Conclusions : This study is to verify the effect of group SI intervention on sensory processing, fine motor function, and social skill for children with sensory integration disabilities. The results were not statistically significant. However, the average score after SI intervention has been improved in the section of fine motor and social skill comparing to that of pre-intervention period. It would have positive impact for children with sensory integration disabilities. It is needed to study with the larger number of target children and more often treatment session are suggested. The confounding variables also should be controlled in the further study.

Objective : The purpose of the study is to find out how group sensory integrative (SI) intervention enhances play skill and social interaction of the children with sensory integration disorders. Method : Three children who were showing problems related in sensory integration received 12 SI intervention sessions. The Sensory Profile (SP) and The Social Maturity Scale (SMS) were accomplished by the subject's primary caregiver. Test of Playfulness (ToP) and Peer Social Interactions Rating Scale (PSIRS) were utilized to investigate the children's play skills and social interactions with their friends. Goal Attainment Scale (GAS) is applied to assess the children's play skill, social interactions with peer, and sensory processing at each session. Data was collected before- and after the intervention and analyzed by the Wilcoxon matched-pair signed rank test with SPSS/WIN version 10.0 and Microsoft Excel. Results : The average scores of ToP, PSIRS, and SMS were increased after the sensory integrative intervention. However, there is no significant difference in the play skills and social interactions between data of pre-intervention and the one of post-intervention. The score of the GAS was frequently increased in terms of the play skills and sensory processing throughout the whole sessions. Conclusions : This study reveals a possibility of that the group sensory integrative intervention may affect not only sensory processing ability, but also play skills and social interactions of children experiencing difficulties of sensory processing. Future research should supplement limitations of this study regarding insufficient number of the subject and the short period of the experiment.

Ammonia-oxidizing bacteria (AOB) are chemolithoautotrophs that play a key role in nitrogen removal from advanced wastewater treatment processes. Various AOB species inhabit and their community compositions vary over time in the wastewater treatment bioreactors. In this study, a hypothesis that operational and environmental conditions affect both the community compositions and the diversity of AOB in the bioreactors was proposed. To verify the hypothesis, the clone libraries based on ammonia monooxygenase subunit A were constructed using activated sludge samples from aerobic bioreactors at the Pohang, the Palo Alto, the Nine Springs, and the Marshall wastewater treatment plants (WWTPs). In those bioreactors, AOB within the Nitrosomonas europaea, N. oligotropha, N.-like, and Nitrosospira lineages were commonly found, while AOB within the N. communis, N. marina, and N. cryotolerans lineages were rarely detected in the samples. The AOB community structures were different in the bioreactors: AOB within the N. oligotropha lineage were the major microorganisms in the Pohang, the Palo Alto, and the Marshall WWTPs, while AOB within the N. europaea lineage were dominant in the Nine Springs WWTP. The correlations between the AOB community compositions of the wastewater treatment bioreactors and their operational (HRT, SRT, and MLSS) and environmental conditions (temperature, pH, COD, $NH_3$, and $NO_3{^-}$) were evaluated using a multivariate statistical analysis called the Redundancy Analysis (RDA). As a result, COD and $NO_3{^-}$ concentrations in the bioreactors were the statistically significant variables influencing the AOB community structures in the wastewater treatment bioreactors.

Objective : The purpose of this study was to investigate the effect of Ayres's sensory integration (ASI) intervention on the sensory processing ability and motor development in children with Developmental Delay. Methods : 9 children in the experimental group and 8 children in the control group participated in this study for Developmental Delay children aged 3-5 years. For research tool, the Short Sensory Profile (SSP), Peabody Developmental Motor Scale-2 (PDMS-2) are used. In the experimental group, individual sensory integration therapy according to principle of ASI was performed for twice a week, 40 minutes, and 16 times for 8 weeks. Methods for the data analysis included Mann Whitney U test, Chi-square test, Wilcoxon's signed rank test, Cohen's d test of SPSS 24.0. Results : In the ASI Intervention group, the sensory processing ability showed statistically significant difference in total score, movement sensitivity, auditory filtering and low energy/weak compared to the control group without ASI intervention (p<.05). In the ASI Intervention group, the motor development showed statistically significant difference in Gross Motor Quotient, Fine Motor Quotient and Total Motor Quotient compared to the control group without ASI intervention (p<.05). Conclusions : In this study, ASI intervention had a positive effect on the sensory processing and motor development in children with Developmental Delay.

Recently in the health service the globalization and opening their market to foreigners are realized in Korea. So, it becomes necessary for the health service institutes to execute their management to focus on service quality to satisfy their customers. We examined the customer orientation of the individual health professional rather than the market orientation concept based on the health institute. For the market orientation of the health institute should require the individual health professional worked there. The hypotheses for the effect of the role conflict, ambiguity, and job satisfaction of the health professionals to their customer orientation were established based on the literature review and previous researches and tested to the 250 health professionals such as health technician, nurse, radiologist, and management clerk in D hospital located in Busan, in summer 2008. First, the hypothesis 'The role conflict between the individual health professionals might effect to the customer orientation' was rejected. Second, the hypothesis 'The role ambiguity of the individual health professional might effect to the customer orientation' was accepted. Third, the hypothesis 'The satisfaction of the individual health professional might effect to the customer orientation' was rejected. and the multiple regression analysis was taken with the dependent variables as each construct of customer orientation-responsiveness, empathy, tangibility, and reliability, and independent variables as role conflict, role ambiguity, and job satisfaction. With these analysis, we found also the role ambiguity effected to the customer orientation.
