Difference of learner speech and loanword phonology is investigated in terms of Korean learners' speech and their loanword adaptation of English words with a post-vocalic word-final stop. When we compared the speech of 12 Korean learners in mid-intermediate level with that of eight English speakers, the learner speech did not reflect loanword phonology of the vowel insertion after a voiced word-final stop (e.g., rib$[\dotplus]$, bad$[\dotplus]$, gag$[\dotplus]$ vs. tip[=], cat[=], book[=]), but, instead, the target phonology of vowel lengthening before a voiced word-final stop (e.g., rib[r.I:b], CAD$[k{\ae}:d]$, bag$[b{\ae}:g]$ vs. rip[rI.p], cat$[k{\ae}t]$, back$[b{\ae}k])$. A longitudinal study of learner speech before and after instruction showed some development toward the acquisition of target phonology. The results indicate that learner speech departs from loanword phonology, and approaches to target speech in a faster rate than direct ratio. Thus, native phonology predicts loanword phonology, but lends little support to learner speech. Our results also indicate that loanword phonology is constant, while learner speech changes toward the acquisition of target phonology.

본 연구는 GIS 진단신뢰성 향상기술 개발을 목적으로, 16개의 인위적 결함을 이용하여 부분방전 신호를 발생시키고 검출하여 그 패턴인식 확률을 높이기 위하여 신경망에 Genetic Algorithm (GA) 을 적용하였다. 이를 위하여 다음과 같은 5가지 서로 다른 신경망 모델을 선택하였다: Back Propagation (BP), Jordan-Elman Network (JEN), Principal Component Analysis (PCA), Self-Organizing Feature Map (SOFM) 및 Support Vector Machine (SVM). 이와 같이 선택된 모델에 동일한 데이터를 학습 시키고 패턴인식 확률을 비교 및 분석하였다. 실험 결과에 의하면, BP의 인식률이 가장 높고 다음으로 JEN의 인식률이 높이 나타났으며, 후자의 경우 모든 결함에 대하여 정확한 패턴분류를 한 반면에 전자의 경우 1.8% 의 분류 오차가 발생하였다. 따라서 인식률이 높은 신경망이 더 정확한 패턴분류를 보장하지 못한다는 실험적 결과를 고려 할 때, 인식률이 높은 두 개의 모델을 선정하여 각각의 출력에 일정한 가중치를 주고 합산하여 새로운 출력을 얻는 방법을 제안한다.

Purpose: The purpose of this study was to investigate the effect of a comprehensive rehabilitation program on grip strength, pinch strength, the shoulder joint function, flexibility, and fatigue in mastectomy patients. Method: The subjects were fifty-five women with breast cancer (27 in the control group and 28 in the experimental group). The subjects in the experimental group participated in a comprehensive rehabilitation program for 10 weeks, which was composed of education, stress management, exercise, and peer support group activity. Results: The results revealed that the increase in grip strength, key pinch, the shoulder joint function, and flexibility (Back & Reach test, Standing & Bending reach test) of the operated extremity, and the decrease in fatigue were significantly higher in the experimental group than in the control group. However, the results revealed that tip strength and palmar pinch of the experimental group increased but there was no significant difference from that of the control group. Conclusions: The 10-week comprehensive rehabilitation program showed much affirmative effect on physical function, and fatigue of breast cancer patients after mastectomy.

The purpose of this study was to investigate preferences and satisfaction levels in maternity and nursing brassiere. A questionnaire was conducted on 302 women from their 20s to 40s who had breastfeeding experience. The questionnaire included questions on participant demographics, purchase behavior, and design preference and satisfaction levels. The majority(98.0%) of the participants had had experience using maternity/nursing brassieres. More than 90% of the participants agreed with the need for maternity/nursing brassieres distinct from regular ones. Shopping online was the most common means of purchasing them. The most and second-most owned fastener types were the detachable shoulder belt type and inside-cup type, respectively. The most selected reason for purchasing or wearing a maternity/nursing brassiere was the convenience of donning and doffing the brassiere during breastfeeding. Participants had lower satisfaction levels with how well maternity/nursing brassieres support and center the breasts, and with the variety of designs available on the market. Respondents indicated that fasteners for breastfeeding should be developed to provide comfort and convenience for breastfeeding. Wearing comfort was reported as the most important factor in purchasing selection, both during the pregnancy and breastfeeding periods. No-wire, back closure, full-cup, U-shape wing, and skin color were the most preferred design styles.

Objectives : This study was designed to investigate incidence rate, clinical features and treatment of headache followed after acupotomy. And based on that, we study correlating between post acupotomy headache and post-lumbar puncture headache(PLPH). Methods : From September 1st, 2007 to December 31st, 2007, the 73 inpatients who admitted to Daejeon Oriental hospital and underwent acupotomy on lumbar spine and cervical spine etc. more than once were observed. Then 9 inpatients who occurred headache after acupotomy was analyzed according to incidence rate, gender, age, clinical features. Results : We investigated clinical features of post acupotomy headache and made comparative study of post acupotomy headache and PLPH. The average frequency of post acupotomy headache was about 12.3%. The risk factors are undergoing acupotomy on lumbar spine, young age. Gender does not affect the incidence of post acupotomy headache. Patients complain of headache which worsen when the patients is upright and improve after the patients lie back down in a few minutes. Those clinical features are similar to PLPH. Conclusions : Although two type of headache have significant similarities, there is no enough evidence to support this study. In addition, the cause and treatment of post acupotomy headache are still unclear. Thus, based on the above study, more studies have to be investigated.

The paper explores the return migration choice of graduates, which takes place during the transition from higher education to the labor market. Graduate students, after a short time in temporary migration to cities for studying, have to make a decision of returning back home or staying in migration in urban areas for working. Drawing on the mechanism identified in the literature on internal migration, this empirical research tests the effects of two factors: place attractiveness and social supports factors on graduates' decision to return migration to hometown. A binary logit regression analysis was conducted with data from 502 surveyed graduates in Hanoi, Vietnam. The analysis of the motives reported by graduates indicates that return migration decisions cannot be reduced to a single dimension. Perceived attractiveness of a region such as quality of living environment, job opportunities, and social context of individuals positively impact on student' decision to return migration after graduation. The research results imply that, in a collectivistic country like Vietnam, students' choice of future career is strongly influenced by their social context, and choosing a place to work is not simply a matter of earning a higher salary or enjoying better working conditions, but is also related to family issues.

This paper addresses the problem of signal acquisition with a sparse representation in a given orthonormal basis using fewer noisy measurements. The authors formulate the problem statement for randomly measuring with strong signal noise. The impact of white Gaussian signals noise on the recovery performance is analyzed to provide a theoretical basis for the reasonable design of the measurement matrix. With the idea that the measurement matrix can be adapted for noise suppression in the adaptive CS system, an adapted selective compressive sensing (ASCS) scheme is proposed whose measurement matrix can be updated according to the noise information fed back by the processing center. In terms of objective recovery quality, failure rate and mean-square error (MSE), a comparison is made with some nonadaptive methods and existing CS measurement approaches. Extensive numerical experiments show that the proposed scheme has better noise suppression performance and improves the support recovery of sparse signal. The proposed scheme should have a great potential and bright prospect of broadband signals such as biological signal measurement and radar signal detection.
