The lightweight bubble mixture soil is used for soft ground rear-filling material by applying reduced weight on structure. However, comparing with the general soil, it is not applied in domestic because of initial phase cost of construction. General soil, which has lower initial phase cost is usually used for rear-filling, but the use of overlay method of general soil is reduced as the number of layers increases. Especially box structure placed in soft ground or the overlay method when gap near pier rear-filling can be replaced with temporary alternative method, however, it can't be a solution to gap by generation of extra weight of thickness of overlaying. Therefore, execute LCC analysis of two alternative-the general and the lightweight bubble mixture soils, which are rear-filling material of box structure- and present economical analysis in order to make resonable decision from the economics. As a result, although the lightweight bubble mixture soil takes higher initial phase cost than the general soil, it has been analyzed to procure economical efficiency by having less cost of maintenance.

This study attempted to investigate the perception of safety of regular polish and gel polish and degree of nail damage. For this, a questionnaire survey and an experiment were performed against women in their 20-50s, and the results found the followings: In terms of effectiveness, safety and degree of nail damage, gel polish was higher than regular polish. In addition, moisture/sebum levels and trans-epidermal water loss (TEWL) decreased after the experiment. Specifically, such reduction was greater in gel polish. When the nail surface was observed by a scanning electron microscope (SEM) after polish removal, gel polish revealed severe nail damage. The above results confirm that gel polish is greater than regular polish in terms of influence on the degree of nail damage. Therefore, it is anticipated that the study results would be available as basic data in keeping nails healthy and beautiful.

The purpose of this study is to figure out the perceptional characteristics of mathematically gifted elementary students by comparing the mathematical reasoning ability and errors between mathematically gifted elementary students and non-gifted students. This research has been targeted at 63 gifted students from 5 elementary schools and 63 non-gifted students from 4 elementary schools. The result of this research is as follows. First, mathematically gifted elementary students have higher inductive reasoning ability compared to non-gifted students. Mathematically gifted elementary students collected proper, accurate, systematic data. Second, mathematically gifted elementary students have higher inductive analogical ability compared to non-gifted students. Mathematically gifted elementary students figure out structural similarity and background better than non-gifted students. Third, mathematically gifted elementary students have higher deductive reasoning ability compared to non-gifted students. Zero error ratio was significantly low for both mathematically gifted elementary students and non-gifted students in deductive reasoning, however, mathematically gifted elementary students presented more general and appropriate data compared to non-gifted students and less reasoning step was achieved. Also, thinking process was well delivered compared to non-gifted students. Fourth, mathematically gifted elementary students committed fewer errors in comparison with non-gifted students. Both mathematically gifted elementary students and non-gifted students made the most mistakes in solving process, however, the number of the errors was less in mathematically gifted elementary students.

This study started from ideas on lack of discussion regarding age integration emphasized as an alternative paradigm for aged society and exclusion of policy target from discussion on age integration. This study analyzed potentiality of age integration through comparing the perception on impacts of age integration between policy target and professional. Results showed that policy target perceived social and individual effects of age integration more sceptically than professional. Also, policy target reported higher levels of agreement on development of age friendly environment and increase in social contribution by the aged as social impacts of age integration. Otherwise policy target, professional showed higher levels of agreement on enhancement of social solidarity and increase in mutual understanding among generations. In perception on individual impacts of age integration, policy target differed from professional by emphasizing extension of self-determination and self-autonomy. Lastly, group membership of policy target or professional significantly determined levels of agreement on positive impacts of age integration.

According to Demand and Capacity Model (DCM), external and internal environments influence the disfluency of children who stutter (CWS). This study investigated the effects of simultaneous changes in motoric and linguistic demands on CWS and children who do not stutter (CWNS). Participants were 4-6 years old CWS and CWNS. A sentence imitation task with changes in speech rate, utterance length, and sentence complexity was used to examine their effects on children's disfluency. When the utterance length changed, CWS showed more disfluency regardless of utterance length and as the speech rate changed, CWS showed more disfluency at fast speech rate than CWNS. When the utterance length and speech rate changed, at fast speech rate, CWS showed more disfluency in both utterances than CWNS. When sentence complexity changed, CWS showed more disfluency than CWNS in complex sentences. Changes in linguistic elements such as speech rate, utterance length, and sentence complexity affect disfluency in CWS, especially when they were exposed to faster, longer, and more complex sentences. This indicates that CWS are vulnerable to fast and complex speech motor control and language processing ability than CWNS. Thus, this study suggests that parents and therapists consider both the speech rate and the utterance length when talking with CWS.

The relationships between the textural properties of cooked rice and hot water-solubles of rice or rice flour were studied. The amounts of solubles or soluble amylose among japonica varieties were similar, but those among Tongil type varieties were different. At the same heating conditions, japonica varieties showed higher contents of solubles as well as soluble amylose than Tongil varieties. The solubles and soluble amylose from rice or rice flour showed a negative correlation with hardness but a positive correlation with adhesivess of rice cooked with optimum water.

본 연구는 한국 나노기술의 발전현황을 살펴보고 나노기업들이 갖고 있는 재무적 특징을 분석한 것이다. 한국의 나노기술은 정부의 집중적인 지원을 받으면서 기업과 대학을 비롯한 연구기관들 사이의 경쟁적인 연구 속에서 단기간에 괄목할만한 성장을 하였다. 그 결과 미국, 일본, 독일에 뒤이은 높은 기술수준을 보유하게 되었다. 이러한 가운데 나노기술을 보유한 기업들에 대한 재무적 특징을 일반기업들과 비교 분석하여 몇 가지 의미 있는 결과를 확인할 수 있었다. 첫째 나노기업들은 일반기업들에 비해 높은 성장을 보이고 있다. 둘째 나노기업들은 일반기업들에 비해서 타인자본의존도가 높게 나타났다. 끝으로 나노기업들의 수익성은 일반기업에 비해서 낮게 나타났다. 이러한 연구결과는 나노기술의 지속적 발전을 위한 정책적 결정에 중요한 시사점을 제시한다. 우선 정부는 나노기술의 산업화를 지원하여 기술의 제품화를 촉진시키는 것과는 별도로 나노기업의 재무구조개선에 관심을 갖고 부채비율을 낮추도록 해야 한다. 그래야만 수익성을 기반으로 한 지속적 성장이 가능하기 때문이다. 이를 위해서 나노기업에 대한 투자세액공제 등의 정책을 녹색성장정책에 포함시킬 필요가 있다고 본다.

본 논문에서는 일반적으로 사용되는 마이크가 잡음에 민감하여 음성인식피치 성능을 저하시키기 때문에 잡음치 영향을 받지 않는 고지향성을 가지는 넥마이크로 입력되는 음성신호에 대한 특성을 고찰하고 기존의 일반마이크 입력 음성을 이용하는 인식시스템에서의 인식성능을 살펴본다. 넥마이크는 일반마이크와 동일한 원리로 음성을 채집하는 목부위에 장착된다. 실험에서 넥마이크에 의한 음성은 일반마이크 입력 음성에 비해 인식 성능이 저하되는 결과를 보여주어 앞으로 새로운 인터페이스의 연구대상으로 여겨진다.
