본 연구의 목적은 장애이해 교육활동을 적용하여 교육활동별, 성별, 연령별 일반유아의 장애인식과 태도변화를 알아보는 것이었다. 본 연구에서는 모두 128명의 유아가 참여하였으며, t 검증을 통해 각 변인별 사전·사후 검사의 차이를 알아보았다. 연구결과 첫째, 각각의 활동은 일반유아의 장애 인식과 태도를 향상시키는데 긍정적인 것으로 나타났다. 모든 활동에서 장애 인식과 태도에 대한 사후점수는 사전점수에 비해 높게 나타났다. 유아들은 일반적으로 지체 장애를 가장 잘 인식하고, 이어 청각, 시각 장애의 순으로 인식하였다. 둘째, 성별에 따른 장애인식과 태도의 변화를 알아본 결과, 여자유아, 남자유아 모두 사전점수보다 사후점수가 높게 나타났다. 셋째, 연령을 막론하고 4세, 5세 유아 모두 장애 인식과 태도는 사전에 비해 장애이해 교육활동 이후 향상된 것으로 나타났다. This research sought to identify changes in disability awareness and attitude of typically developing young children through disability-understanding activities based on their sex and age. The research targeted three classes of 5 year-old-children and one class of 4-year-old children in a kindergarten located in Daegu City. The results of the study are as follows: First, the children's overall awareness on peers with disabilities was increased. Second, it was found that there was a significant difference in changes in awareness and attitude according to each educational activity, such as listening to fairy tales, sharing stories, and experience in simulated disabilities. Third, children were found to undergo changes and show affirmative attitude toward peers with disabilities, in terms of changes in their attitude towards developmental retardation according to sex and age after they were offered various disability-understanding activities.

<P><B>Abstract</B></P> <P>High conversion efficiency (<I>η</I>) values have been obtained from modified CuS film electrodes electrochemically deposited onto Glass/FTO. The modification involved pre-annealing the film followed by coating with tetra(-4-pyridyl)porphyrinato manganese (MnTPyP<SUP>+</SUP>) ions embedded inside a polyethylene (PE) matrix. The Glass/FTO/CuS/MnTPyP/PE electrodes exhibited enhanced photo-electrochemical (PEC) characteristics under solar simulated illumination (5.6mW/cm<SUP>−2</SUP>) in aqueous media, compared to the as-prepared Glass/FTO/CuS films which showed no PEC activity. Up to 17.4% efficiency and 85% fill factor (FF) values were obtained from the modified film electrodes. Such characteristics have not been widely known for metal chalcogenide based film electrodes before. Different pre-annealing temperatures were attempted and the 250°C temperature, followed by quenching, showed favorable results. Different aqueous redox couples were studied and the environmentally safe FeCl<SUB>2</SUB>/FeCl<SUB>3</SUB> aqueous system showed highest PEC characteristics.

Until now, research on the qualifications of a Korean teacher has emphasized the fact that the teacher’s voice affects the delivery of classes and the learner’s satisfaction. However, similar research has not been done on Korean teachers’ awareness of their voices as an important qualification and what a good voice is for a Korean language teacher. Therefore, this study explores the perceptions and experiences regarding the importance of Korean language teachers’ voices through in-depth interviews with three experienced Korean language teachers. As a result, voices of teachers could influence learners’ communication abilities and affective factors, teachers’ satisfaction and confidence based on the cases in the education field. In addition, the elements of a good voice that Korean teachers should consider were derived through interview analysis. Moreover, a self-checklist of Korean teachers’ voices was designed based on the elements retrieved. The expectation of this study is to provide primary data for the pedagogy of Korean language teaching and the studies on Korean teacher education consulting. (Busan University of Foreign Studies)

Whole-body vibration exercise (WBVe) can provide proper somatosensory stimulation and improve muscle strength in stroke patients. This study investigated the effects of WBVe on gait function and cortical activity in patients with chronic stroke. Thirty stroke patients were randomly assigned to either the WBVe or the control group. The WBVe group received the vibration in a half-squat position for 5 minutes at an intensity of 20 Hz. The control group kept the same posture but did not receive the vibration. Cortical activity was investigated using functional near-infrared spectroscopy (fNIRS). Gait function was assessed by a 10-m walk test (10MWT), a timed up and go (TUG) test, a Fugl-Meyer Assessment, and a Tinetti Performance-Oriented Mobility Assessment (TPOMA). In group analysis of the fNIRS data, oxygenated hemoglobin concentration was significantly increased in the ipsilesional supplementary motor area, bilateral sensorimotor cortex, and contralesional prefrontal cortex in the WBVe group compared to the control group (p < 0.05). Functional assessment demonstrated a significant interaction between time and group for the 10MWT and TUG test, suggesting that the WBVe group demonstrated meaningful improvement after intervention (p < 0.05). These results suggested that WBVe modulated the cerebral cortical activities and resulted in improvement of gait function in chronic stroke patients.

The objective of this study was to evaluate the effect of the amount of water and several kinds of sweeteners on the texture such as grain appearance, softness, moistness, chewiness, cohesiveness, gumminess and elasticity of Backsulgi when one manufactures Backsulgi. Different amount of water of 30ml, 60ml and 90ml/350g of powdered rice and such sweetners as sugar, honey and syrup were employed for the experimental treatments. The evaluation of these results were dependent on statistical data of some scores that were obtained through sensory evaluation and Instron Universal Testing Machine. According to this sensory evaluation, the texture of Backsulgi was more affected by the change of water quantity than that of sweeteners. Judging from the results of Instron Universal Testing Machine, it was found that there were no statistically significant differences in each treatment of the cohesiveness, elasticity and hardness of Backsulgi, but some statistically significant difference was observed in each treatment of the gumminess and chewiness of Backsulgi(p<0.05).

<P><B>Abstract</B></P> <P>Zinc oxide (ZnO) nano-particles were chemically deposited onto montmorillonite (MONT) clay particles. The composite ZnO@MONT was then characterized and used as a catalyst for photo-degradation of aqueous tetracycline. Unlike earlier studies, solar simulated light can be effectively used in this work. The composite shows high efficiency as adsorbent and as a photo-degradation catalyst. Both adsorbed and dissolved tetracycline molecules undergo mineralization under the photo-catalytic conditions, and up to 94% of the contaminant gross amount is completely mineralized. Other forms of ZnO particles, commercial ZnO and synthetic ZnO particles were examined in separate experiments. The ZnO@MONT is superior to both pristine counterparts. The ability of tetracycline to sensitize the supported ZnO particles, to solar simulated light, before being photo-degraded itself, is discussed here for the first time. In addition to enhanced catalytic activity of the ZnO@MONT, the composite can be efficiently recovered and reused with no significant loss of efficiency.</P> <P><B>Highlights</B></P> <P> <UL> <LI> ZnO particles supported onto montmorillonite are useful catalyst for tetracycline degradation by simulated solar light. </LI> <LI> The ZnO@MONT is more effective catalyst than pristine ZnO, due to high adsorption by support. </LI> <LI> Contaminant facilitates own light-driven degradation by sensitizing the wide bad gap ZnO catalyst. </LI> <LI> ZnO@MONT catalyst can be recovered and reused with no significant loss in its efficiency. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>Tetracycline may self-sensitize its own degradation with simulated solar light Using ZnO supported onto montmorillonite.</P> <P>[DISPLAY OMISSION]</P>

계층분석과정의 간호적용에 관한 연구 -미국의 미래 간호교육의 예견-

Han, Kyung-Ahe Korean Society of Nursing Science 1986 Journal of Korean Academy of Nursing Vol.16 No.1

복잡한 사회문제해결에 유용한 접근방법의 하나인 계층분석과정은 수학자인 사티(Saaty)가 개발한 것으로서 이미 사회과학의 여러 분야에 적용되고 있다. 본 논문의 목적은 이 계층분석과정을 간호교육과 관련된 문제에 적용해 봄으로써 이 방법이 실제 문제해결을 위한 유용한 접근방법이 될 수 있는가를 고찰해 보는데 있다. .현대사회문제들은 다양한 관련요소, 그 요소들간이나 다른 문제들과의 복잡한 상호관계, 다수의 의사결정자의 참여, 무한한 대안, 문제의 결과에 대한 불확실성 등으로 인하여 단순한 모델이나 간단한 논리적 혹은 직관적인 판단에 준하여 일시에 해결하기 어려운 경우가 많다. 이러한 상황 하에서 문제와 관련된 요소들을 찾아내고 그 요소들을 계층적으로 분석하여 단계적으로 문제해결에 접근하는 계층분석과정을 활용함으로써 사회과학분야의 문제해결에 유용한 수단이 될 수 있다. 또한 문제와 관련된 요소를 규명하고 계층적으로 분화하는 과정에서 그 문제에 대한 보다 명확한 이해, 분석 및 현상의 흐름을 더 잘 인해하게 된다. 계층분석과정은 1) 계층구조의 설정 2) 구성요소들의 중요도 측정 3) 중요도에 따른 우선 순위의 산정 4) 우선 순위의 일관성 검토과정으로 요약된다. 본 논문에서는 이러한 과정을 통하여 미국 간호계에서 심각한 문제로 대두되어온 기본교육제도상의 쟁점(Issue of Entry into Practice)에 대한 문제 해결책이 마련되는지를 시도하였다. 즉, 기본교육 제도에 영향을 미칠 수 있는 요인들을 규명하여 계층화하고 계층내에 위치하는 구성요소들의 수평적 관계와 계층간의 수직적 관계를 체계적으로 검토하여 간호교육의 미래를 예측해 보았다. 간호교육제도에 영향을 미칠 수 있는 주요 요인들의 계층화는 거시적 환경차원(factors), 관련 이해자 집단차원(actors), 이해자 집단의 목표차원(objectives), 목표달성을 위한 정책차원(Policies), 그리고 간호교육제도의 미래를 예견한 시나리오(scenario)로 이루어졌다. 각 계층을 따라 단계적으로 중요도를 비교하여 최종적으로 각 시나리오의 우선순위 중요도(priority weight)를 구하였다. 각 시나리오의 우선순위 중요도를 간호교육과 관련된 4가지 차원들(학생, 교수, 교육기관, 직업)을 구성하고 있는 특성들에 가중하여 결과를 해석 하였다. 간호교육의 미래에 정치적(55%)과 경제적(25%) 요인이 가장 강한 영향을 미치고, 관련자중에서는 병원(38%) 의사(33%) 그리고 정부(23%)의 순으로 영향을 미친다고 분석되었다. 의외로 간호원 자신들은 큰 영향력이 없는 것으로 보여졌다. 4개의 시나리오 중에서는 그 우선순위 중요도가 현상유지(33%) 자발적4년제(32%), 강제 4년제(19%), 그리고 2~3년제의 우위(18%) 순으로 나타났다. 최종 시나리오 결과를 요약하면 1) 전체 학생수는 감소하나 양질의 간호학생수는 증가하며 2) 박사학위를 소지한 간호학 교수 및 전체 교수의 수가 증가할 것이다. 3) 전체 간호교육기여의 수는 약간 줄 것이며 그중 4년제 기관이 증가하고 반면에 2~3년제의 기관은 감소할 것이다. 4) 전문간호원이 되기 위한 입학용이도에는 별차이가 없겠으나 간호원들의 보수, 지위 및 자율성이 증가하면서 전반적인 간호의 질이 향상될 것이다. 계층분석과정의 적용으로 미국 간호교육계의 가까운 미래를 위와 같이 예견하여 보았으나 이 과정은 예견 뿐 만 아니라 일반적인 의사결정이나 문제 해결의 도구이외에도 복잡한 사회문제

The purpose of this study was to propose effective marketing communication strategies for overseas Korean restaurants through a multilateral comparison analysis of American, Chinese, and Japanese consumers` attitudes towards communication media and Korean restaorants. The survey was written in English, Chinese, and Japanese, with guideline for surveyors, and conducted using both online and offline methods. Samples were collected from five major cities - Los Angeles, New York, Tokyo, Beijing and Shanghai, which are the foothold for the globalization of Korean food. When it comes to attitudes towards communication media, word-of-mouth showed a high mean value, indicating it as the most useful and reliable media recognized by consumers who visited Korean restaurants. Furthermore, the necessity of recognizing the importance of visual communication in the physical environment of Korean restaurants and specialized websites, featuring restaurants and gourmet food, was observed. Consumers in all three nations chose word-of-mouth as the most useful and reliable media for learning about Korean restaurants. In addition, American consumers highly depended on signage and restaurant exteriors. Chinese consumers highly recognized the usefulness and reliability of offline media, such as newspapers, magazines, and events, while Japanese consumers considered online media, such as gourmet websites, blogs and social networks, as useful and reliable sources. A significmuly positive attitude and high value was observed in all who had visited Korean restaurants, American and Japanese consumers had a significantly higher rate of intention to visit Korean restaurants in the future and to tell others about their satisfaction with Korean restaurants. Meanwhile, the average rate of prior preference for Korean restaurants (when choosing restaurants) was the lowest in all three countries. This study is useful for both the Korean government and food enterprises abroad to plan and develop marketing communication strategies properly for overseas Korean restaurants.

South Korea and North Korea have restricted normal people’s contact for about 60 years in accordance with the National Security Law and the Law for Mutual Trade and Cooperation between South and North Korea since ceasefire in 1953. The South Korean society has developed economy carried out exchanges with other countries, and with growing foreign workers and multicultural families it can approach various cultures all over the world. In addition, the South Korean has respected individuals’ value and diversity since the pro-democracy movement of the 1980s while the North Korean society has made an idol of father and son Kim Il-sung and Kim Jung-il under the pretext of Juche Idea with isolation from the national community. The two Koreas has not communicated with each other under the different political system for 60 years, so there are concerns regarding heterogenization between South Korea and North Korea and the solutions to restore inter-Korean homogeneity are discussed. This study looked into possibility to supply and develop unification cultural contents for restoring inter-Korean cultural homogeneity through the compilation cases of Digital Encyclopedia of Hangsan Culture. Digital Encyclopedia of Hangsan Culture is very meaningful academically to summarize and provide North Korea’s local culture information, and at the same time understand North and South Koreas that are divided for 60 years as well as restore homogeneity. Moreover, Digital Encyclopedia of Hyangsan Culture is the material with summarized cultural asses in North Korea in order for normal people to approach easily. It is regarded to have very high competiveness as a unification culture contents to restore inter-Korean homogeneity.
