This study was to investigate the effects of music-combined respiration and oral motor training on the voice of healthy elderly. 27 women attending a senior center in Seoul participated and were randomly assigned to the experimental (n = 16) and the control group (n = 11). Subjects attended music program(25 minutes per session) once a week for 4 weeks. For both groups, Fundamental Frequency (F0), Maximum Phonation Time (MPT) and Sequential Motion Rates (SMR) were measured using the Praat speech analysis program before and after the training. The results showed statistical significance in scores of intensity, F0, MPT, and SMR in the experimental group while only intensity was statistically significant in the control group. Considering that, the increasing life expectancy and growing number of older adults, their quality of life has been important. So this study suggests that the respiration and oral motor training would be effectively incorporated into training and services for this population.

A new awareness on design in economy and business domain has shifted the focus of design education from the description and presentation to the creativity. This contextual change raises new awareness on the importance of the design management training program. The goal of this research is to suggest a program of design management training program in Korean context. For the purpose, the history of design management activity is briefly reviewed. And then the curriculum between Korean design schools and design management schools abroad is reviewed. The result shows that the design management schools abroad emphasize leadership based on practicality and the program is also ran by School of Business Management. The curriculum consists of leadership program and creativity program. The leadership comprises individual, personal, and collaborative. The leadership takes the role of catalyst in the organization to draw a creativity and raise it. So both leadership and creativity are inseparable. The result of creativity, however, differ from one another based on individual's capacity, procedure, and social context. Thus, it is important to develop a design management program which considers individual, social context, as well as economy and business domain.

In this paper, a computer simulation is developed for isotachophoretic protein separation in a serpentine micro channel for optimal lab on a chip design using 2D Finite Element Method. This 2D ITP model is composed of 5 components such as hydrochloric acid as Leader, caproic acid as terminator, acetic acid and benzoic acid as two proteins, and histindine as background electrolyte. The computer model is based on mass conservation equation for 5 components, charge conservation equation for electric potential, and electro neutrality condition for pH calculation. For the validation of the 2D spatial ITP model, the results are compared with the Simul5 developed by Bohuslav Gas Group. The simulation results are in a good agreement in a ID planar channel. This proves the precision of our model. The 2Dproteinseparation is conducted in a 2D curved channel for Lab on a chip design and dispersions of proteins are revealed during the electrophoretic process in a curved shape.

Recently, various air pollution factors have been measured and analyzed to reduce damages caused by it. In this process, many missing values occur due to various causes. To compensate for this, basically a vast amount of training data is required. This paper proposes a statistical techniques that effectively compensates for missing values generated in the process of measuring ozone, carbon dioxide, and ultra-fine dust using a small amount of learning data. The proposed algorithm first extracts a group of meteorological data that is expected to have positive effects on the correction of missing values through statistical information analysis such as the correlation between meteorological data and air pollution level factors, p-value, etc. It is a technique that efficiently and effectively compensates for missing values by analyzing them. In order to confirm the performance of the proposed algorithm, we analyze its characteristics through various experiments and compare the performance of the well-known representative algorithms with ours.

우리나라는 현재 개발되어 적용되고 있는 홍수피해잠재능(Potential Flood Damage, PFD) 산정방법은 잠재성요소(인구, 자산, 사회기반시설, 도시화율)와 위험성요소(홍수피해액, 확률강우량, 외수방어능력, 댐 및 저수지, 내수방어능력)로 산정 후 지역평가를 통해 그룹(A,B,C,D)별로 평가하고 있다. 하지만, 홍수피해잠재능(PFD) 산정인자가 많아 자료조사 및 구축에 많은 시간이 소요 되며, 인자별 다양한 공간적 범위로 인해 실무 적용에 어려움이 있다. 또한, 소구역 단위 평가로 인해 하천의 침투 특성을 반영하지 못하여 하천 주변의 중요도 평가가 미흡한 실정이다. 이를 위해 본 연구에서는 중요도 분석 인자 단순화를 통해 자료 조사 및 구축 시간 단축과 더블어 위험성요소를 내포하는 홍수위험지도 사용을 통해 작업을 간소화하고, 하천 주변까지 고려하여 중요도 평가하는데 목적이 있다. 본 연구에서는 낙동강권역을 대상으로 홍수위험지도 및 중요도 분석 인자(인구, 자산(공시지가), 시회기반시설(도로,철도), 도시화율(시가화지역)) 공간정보를 구축하였고, 점수할당법에 의한 인자별 중요도 분석 및 상관성 분석을 통해 피해우선순위를 분석하였다. 분석결과, 인구·자산(공시지가) 인자가 높은 구역이 대체로 사회기반시설 연장 및 도시화 면적이 높게 나타났으며, 하천의 치수단위 구역별 중요도 분석시 인구·자산(공시지가) 두가지의 인자로도 치수안전도 결정에 활용이 가능할 것으로 판단된다.

The purpose of this study is to identify the characteristics of school library services using the RGT (repertory grid technique), and to examine whether there are differences in the perceptions and internal experiences of school library services between human resources (librarian teachers, subject teachers, and librarians). I used indicators such as element intensity, construct extremity, discrepant constructs, and implicative dilemmas to analyze the characteristics of school library services. The elements of the repertory grid were set to 9, and 14 constructs were set through focus group interviews with 3 librarian-teachers. The GRIDCOR 6.0, which can be accessed online, was used to complete the repertory grid for 30 graduate students of the College of Education, and 6 of them were selected and analyzed, considering the demographic characteristics. From the perspective of element intensity, it was found that the following school library services are important and influential: resource management, teacher-librarian collaboration, and reading and information counseling services. The clarity of one's role, the actual performance, and self-regulatory ability were ranked high from the perspective of constructs intensity.

This research aims to identify risk factors for fall accidents at small and medium-sized construction sites through a comprehensive regression analysis. Initially, the study involved collecting a decade's worth of fall accident data from these sites. A t-test confirmed a significant variation in the treatment duration following fall accidents between two distinct groups: small and medium-sized versus large construction sites. Subsequently, a regression analysis was conducted to establish a model highlighting the risk factors associated with safety accidents. The factors influencing fall accidents were determined to be, in descending order of impact, the time of the accident, the day of the accident, and the occupational classification. The findings from this study are expected to serve as foundational data for enhancing policies and conducting statistical analyses tailored to construction site sizes. They also provide crucial information for future research on risk quantification at small and medium-sized construction sites.

In this paper, I present a programming idiom for extending message protocols incrementally in C++, where effectiveness of message transmission is regarded as static binding. Our techniques analyze message protocols with a message handler that examines message types, parameters, and effectiveness dynamically. The result of this analysis is not only to cope with incremental extension of message protocols effectively but also to simulate all essential elements of the object-oriented programming. This result also makes it possible to write high level of procedure like message transmission to object groups.

본 연구에서는 인터넷 비즈니스 웹사이트를 물리적인 제품을 판매하는 웹사이트와 디지털 제품을 판매하는 웹사이트간에 웹사이트 평가 영역을 잣대로 삼아 차이가 발생하는 지를 분석하였다. 웹사이트 평가영역에 사용될 평가기준을 도출하기 위해 성공한 국내외 웹사이트 사례와 평가업체의 기준, 그리고 성공적인 웹사이트 구축요소 등을 토대로 새로운 평가기준 모형을 제시하였다. 이 모형을 토대로 고객지향적 요인, 컨텐츠 및 제품 정보와 관련된 요인, 디자인 및 인터페이스와 관련된 요인, 그리고 사용성과 관련된 요인 등 4가지의 중요요인과 각각에 대한 전체 15개의 하위 평가요인을 도출하였다. 그리고 직접적인 고객 지각 데이터를 통해 실증 분석함으로써 두 그룹간의 차이를 규명하고자 하였다. 결론적으로 대분류 요인에서는 고객지향적 요인이, 소분류 요인에서는 거래상의 안전성, 메뉴의 적절성, 그리고 참신성 등이 유의적인 결과가 도출되었다.
