There are 27 science education institutes for gifted education institutes in the university with support from the MSIT (Ministry of Science and ICT). Mathematics, physics, chemistry, biology, earth sciences, and information classes are given in each science education institute for the gifted. The authors developed a curriculum with components of computing thinking for information-gifted students. To determine if the curriculum is effective on the computer scientific attitude of the information gifted, TOSRA was modified and the test was then developed. Information students were educated at K university's science education institute for the gifted with the developed curriculum for one year and the computer scientific attitude of them was tested. According to the test results, there was a significant difference in the computer scientific attitude of the curriculum conducted at the institute at 0.05 level of significance. Statistically significant differences were observed in the social implications of computer science, attitudes of computer scientific inquiry, and the normality of computer technicians at the level of significance of 0.05. On the other hand, there were no significant differences in the adoption of computer scientific attitudes, the enjoyment of computer science lessons, leisure interest in computer science, and career interest in computer science.

Artificially or naturally contained texts in the natural images have significant and detailed information about the scenes. If we develop a method that can extract and recognize those texts in real-time, the method can be applied to many important applications. In this paper, we suggest a new method that extracts the text areas in the natural images using the low-level image features of color continuity. gray-level variation and color valiance and that verifies the extracted candidate regions by using the high-level text feature such as stroke. And the two level features are combined hierarchically. The color continuity is used since most of the characters in the same text lesion have the same color, and the gray-level variation is used since the text strokes are distinctive in their gray-values to the background. Also, the color variance is used since the text strokes are distinctive in their gray-values to the background, and this value is more sensitive than the gray-level variations. The text level stroke features are extracted using a multi-resolution wavelet transforms on the local image areas and the feature vectors are input to a SVM(Support Vector Machine) classifier for the verification. We have tested the proposed method using various kinds of the natural images and have confirmed that the extraction rates are very high even in complex background images.

정신과 영역의 환자를 위해 간호원의 역활을 필요로 한 이래 여러 가지 간호의 개념으로 간호원의 역할이 변화되어오고 있다. 정신과 환자의 안전만이 가장 큰 치료의 중심일 때는 병동열쇠의 위엄에 곁따라 보호관리에만 치중해 왔으며 정신의학에서 약물요법, 전기요법의 치료과정이 생기면서 간호원의 역할 변화 및 지식의 요구를 필요로 하게 되었으며, 환경과 개인의 밀접한 관계를 중시해오면서 치료적 환경속으로 환자의 인간적 치료가 강조되었을 때 의사소통과 대인관계의 인적 환경으로써 또한 간호원의 역활이 중요시 되어왔다. 이런 관점에서 치료적 환경에 대한 정확한 이해는 간호행위과정의 불완전을 제거하며 보다 활발한 정신과 환자간호에 기여하는 일 일 것이다. DR. Bartom은 병실 환경이 비생산적이고 비 치료적일때 성격의 변화는 물론 행동적 특성의 변화까지 가져올 수 있다고 말했다. 즉 무감동적이고, 무조건적 순종이 있으며 솔선하여 행하는 행위가 줄고 장래 계획에 대한 자극이 줄어들고 될대로 되어 가는 상태 그 자체에 머물러 있어 인간의 특징적 의미와 가치를 상실하게 된다는 것이다. 정신과 병실은 잠정적 체류지로 보아야 하겠고 이 체류지에서의 영향이 환자에게 보다 유익하게 끼칠려면 간호원이 지속적으로 치료적 분위기를 유지해야 할 것이다. 치료적 입장으로서의 간호의 활동 초점은 대인관계에서 환자의 의식수준과 자아관련 수준에서의 취급이 무의식 수준에서의 탐구조사보다 바람직하다. 치료적 가치로써 치료적 환경의 이론적 근거를 DR. Sullivan 은 인간의 상호관련 문제에 두고 있다. 즉 상호작용이 존재하는 환경은 어떠한 곳이든 성격에 영향이 있고 이 성격은 대인관계의 복잡성으로부터 결코 떨어질 수 없다는 얘기다. 자아구성 또한 환경의 영향을 받는데 Cumming은 병동환경과 자아구성 재동기간에 밀접성을 시사한바 있다. Visher와 O'sullivan은 정신과적 치료중에서 일상생활에서 경험되어지는 의사소통과 대인관계속에서 학습되어지는 여러 가지가 있기 때문에 매일의 활동획이 치료적 방향으로 계획되어 져야 한다고 말했다. Maxwell Jones 또한 치료적 환경의 유용한 가동은 전 직원의 기여에 있으며 이는 정신건강을 최적으로 올려 줄 것이다. 라고 말했다. 이러한 상황에서 간호원은 의미 없이 환자의 감정 욕구를 깨닫지 못하고 감정지지를 주지 못하며 정서적 긴장을 예방하지 못한 체 환자와의 관계를 유지한다면 현대간호의 개념에서 이탈되어지고 발달되어지지 못한 미숙아 현상이 유지 될 것이다. 보다 바람직한 치료적 환경 유지는 간호로써 환자에게 기여해 주는 일이다. 간호의 역활과 더불어 전문적 태도는 따뜻하고 포용성 있게 그리고 융통성 있게 대함은 물론 간호인 자신의 "자기이용"을 깊이 그리고 치료적으로 이용할 것을 깨달아야 할 것이다. 즉 정신과 병실에서의 간호원 존재 자제가 환자에게 미치는 영향도 고려해야 한다는 것이다. 덧붙여 환자를 위한 일주일 병동 행사표를 Model로 제시하였고 그 안에서의 간호원의 역활을 약술하였다.

In this study, we developed a learning progression for the structure of the solar system using multi-tier supply form items and validated its appropriateness. To this end, by applying Wilson's (2005) construct modeling approach, we set up 'solar system components,' 'size and distance pattern of solar system planets,' and 'solar system modeling' as the progress variables of the learning progression and constructed multi-tier supply form items for each of these variables. The items were applied to 150 fifth graders before and after the classes that dealt with the 'solar system and star' unit. To describe the results of the assessment, the students' responses to each item were categorized into five levels. By analyzing the Wright map that was created by applying the partial credit Rasch model, we validated the appropriateness of the learning progression based on the students' responses. In addition, the validity of the hypothetical pathway that was established in the learning progression was verified by tracking changes in the developmental level of students before and after the classes. The results of the research are as follows. The bottom-up research method that used multi-tier supply form items was able to elaborately set the empirical learning progression for the conceptualization of the structure of the solar system that is taught in elementary school. In addition, the validity of the learning progression was high, and the development of students was found to change with the learning progression.

The purpose of this study was to investigate the communication structures that science gifted students used in small group activities, and to examine the relationship between communication styles and their achievement level. Eight small groups,5 members in each, participated in small group activities, in which they discussed how to calculate the average density of the earth. The communication structures and the achievement level presented in the group activities were analyzed using Pajek, Ucinet 6.0. As a result, we classified the communication styles of science gifted students into monopolistic type and co-ownership type according to the degree of dispersion of the interaction. We also classified it into $D_H{\cdot}N_H$ type, $D_H{\cdot}N_L$ type, $D_L{\cdot}N_H$ type, and $D_L{\cdot}N_L$ type based on the density and network centralization of interaction. The achievement levels of gifted students in their group work were affected by the density of interaction and the network centralization in small group activities, not by the dispersion of interaction among the members of the groups. Therefore, we recommend that teachers make the communication relevant to solving problem when they utilize a small group activity in science teaching.

A 5 days working system and a 6 days working system will be put in force at a food service consumption behavior of company workers. As a 5 days working system have adopted company, which the number of employee is more than 50, from July 1, 2007. The purpose of this paper is to study the In food service consumption behavior of company workers. There is no doubt that it is only way of surviving In current society to analyze the change of social situation and actively cope with the development. Especially, in the field of restaurant industries, they have to be equipped with a great store of experience and skill, theory and practical business, pertinent and rapid disposal. Consequently, it is very important to know the objective and practical knowledge for the restaurant industries trend by having a through grasp of the need of consumer and their propensity to consume. In order to study motives of eating-out and restaurants selection, office workers, who live in the national capital region, are interviewed. The period of interview is from Oct 1 to Nov 20, 2007. According to the result of interview, The most workers prefer to eating-out on week with family and friends. But family is eating-out the more preference to weekend compare to friends. And it is deduced that restaurant near tourist resorts or outside the city rather than in downtown will be prosperous with this result. That is to say, workers go out to eat delicious food regardless of traffic problem and distance, with the increase of national income and the car holding. This paper is worthy of notice in terms of trying to find the relevance between the working system and the restaurant industries development. In after research, I expect the more synthetic and deeper study should be made though the more technical methods.

The administrative employees of government were analyzed on their levels of psychosocial stress and job satisfaction to reveal the various factors related to them. The self-administered questionnaires were performed, during the period between May 25th, 2007 and June 5th, to 550 individuals in the service of general administration located in Daejeon City. The Survey items included subjects' socio-denographic and job-related characteristics, health-related behavior pattern, locus of control, sense of self-esteem, psychosocial stresses and degree of job satisfaction. The study results indicate that the level of stress or job satisfaction is so complicatedly influenced by variable factors such as socio-demographic characteristics, job-related characteristics, health-related behaviors, or social psycologic factors like type A behavior pattern, internal locus of control, self-esteem or stress coping. Thus, the effective strategy for stress reduction and increase of job satisfaction among governmental employees requires additional programs.

Based on data obtained from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted by Korea Centers for Disease Control & Prevention (KCDC), this study analyzed the relationship between existence of the spouse, number of family members, and disease afflictions of the Korean elderly, and factors affecting their quality of life. The collected data were analyzed by Chi-square test, t-test and One-way Anova, using the SPSS / WIN 25. Our comparative analysis on the health status and quality of life revealed that individuals in the singles group had significantly more diseases than the married group. The singles group considered their health was subjectively poor, whereas the quality of life of the married group was higher. Analyzing the characteristics of chronic disease and activity restriction showed significantly higher prevalence of several diseases in the singles group. Besides, the singles group revealed significantly higher limitations of activity. Taken together, our results reveal a difference in the health status, quality of life, and the presence of chronic diseases in accordance to existence of the spouse, indicating that having a spouse increases the level of health and quality of life of the elderly.

The purpose of this study was to compare and analyze changes to the middle school mathematics textbooks of third mathematics curriculum period and seventh mathematics curriculum period. This study put the math curricula from the third to the sixth one in third mathematics curriculum period as those math curricula witnessed the maintenance of industrial society paradigm. And then it put the math curricula from the seventh one to current the 2009 revised mathematics curriculum in seventh mathematics curriculum period as the knowledge-based information society paradigm has continued throughout those math curricula. Based on those period categories, We compared and analyzed changes of the middle school math textbooks. For the comparison and analysis of math textbooks between the two periods, this study set the unit organization system, unit goal, task type and content development approach as analysis elements in the unit of 'Nature of Figures' in the second grade math textbooks for middle school. As a result of the research, it was confirmed that the textbooks of the two periods had many changes in the unit organization system, but the unit goal, task type, and content development approach stayed in low level goals and task type that require conceptual and procedural.
