Purpose: This study was designed to explore the stage distribution of subjects according to stages of change for exercise and to identify factors that could discriminate subjects in various stages. Methods: The sample consisted of 182 subjects who had metabolic syndrome. The instruments used in this study were the stage placement instrument for exercise, the metabolic syndrome knowledge and metabolic syndrome health belief scale, and the metabolic syndrome exercise self efficacy scale. Data were analyzed using chi-square, ANOVA, and discriminant analysis by using the SPSS 19.0 program. Results: For exercise stages, exercise efficacy, occupation, and exercise benefit showed high standardized canonical discriminant function coefficients. Subjects in precontemplation/contemplation stage for exercise were more likely to have occupations, had less exercise efficacy and exercise benefit than those in other stage. Conclusion: This study implies that the level of exercise efficacy and exercise benefit of subjects in precontemplation/contemplation stage need to be enhanced in developing exercise program incorporating the stage of change for metabolic syndrome patients.

Purpose: This study was carried outto compare dietary self-efficacy, obesity stress, and obesity-related quality of life (OQOL) according to BMI and stages of change in vegetable consumption. Methods: A convenience sample of 326 nursing students agreed to complete a questionnaire. Data were collected from October 7 to October 18, 2013. Results: Obesity stress and obesity-related quality of life were significantly different according to BMI. Dietary self-efficacy showed a significant difference between the pre-contemplation/contemplation stage, preparation stage, and action/maintenance stage (F=50.18, p<.001). With obesity stress, there was a significant difference between the PC/C, P, and A/M stages (F=17.63, p<.001). Dietary self-efficacy had a positive correlation with OQOL (r=.11, p<.001) and a negative correlation with obesity stress (r=-.14, p=.012). And obesity stress had a negative correlation with OQOL (r=-.45, p<.001). Conclusion: These findings emphasize that nutritional-intervention programs for changes in behavior during the PC/C and P stages of change in vegetable consumption need to develop strategies to enhance dietary self-efficacy for nursing students.

This article performs a detailed data scrutiny on a chronic kidney disease (CKD) dataset to select efficient instances and relevant features. Data relevancy is investigated using feature extraction, hybrid outlier detection, and handling of missing values. Data instances that do not influence the target are removed using data envelopment analysis to enable reduction of rows. Column reduction is achieved by ranking the attributes through feature selection methodologies, namely, extra-trees classifier, recursive feature elimination, chi-squared test, analysis of variance, and mutual information. These methodologies are ranked via Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) using weight optimization to identify the optimal features for model building from the CKD dataset to facilitate better prediction while diagnosing the severity of the disease. An efficient hybrid ensemble and novel similarity-based classifiers are built using the pruned dataset, and the results are thereafter compared with random forest, AdaBoost, naive Bayes, k-nearest neighbors, and support vector machines. The hybrid ensemble classifier yields a better prediction accuracy of 98.31% for the features selected by extra tree classifier (ETC), which is ranked as the best by TOPSIS.

In the paper of 'Natural Selection Favors AIs over Humans,' Dan Hendrycks applies principles of Darwinian evolution to forecast potential trajectories of AI development. He proposes that competitive pressures within corporate and military realms could lead to AI replacing human roles and exhibiting self-interested behaviors. However, such claims carry the risk of oversimplifying the complex issues of competition and natural selection without clear criteria for judging whether AI is selfish or altruistic, necessitating a more in-depth analysis and critique. Other studies, such as ''The Threat of AI and Our Response: The AI Charter of Ethics in South Korea,' offer diverse opinions on the natural selection of artificial intelligence, examining major threats that may arise from AI, including AI's value judgment and malicious use, and emphasizing the need for immediate discussions on social solutions. Such contemplation is not merely a technical issue but also significant from an ethical standpoint, requiring thoughtful consideration of how the development of AI harmonizes with human welfare and values. It is also essential to emphasize the importance of cooperation between artificial intelligence and humans. Hendrycks's work, while speculative, is supported by historical observations of inevitable evolution given the right conditions, and it prompts deep contemplation of these issues, setting the stage for future research focused on AI safety, regulation, and ethical considerations.

This study was conducted to find out the factors affecting the stages of behavioral change about GMO(n=202 university students). 52.0% of the respondents had no experience in GMO education, the stages of pre-contemplation and contemplation were 35.6% and 29.7%, respectively. Experience and awareness on GMO were the highest at 86.6% and 51.5%, respectively, and 55% of the respondents did not know about the implementation of the labeling system. Positive and negative perceptions on GMO score were 3.41 and 3.22, respectively. The need for the full labeling system of GM foods was 56.4%, the intention not to pay when the price rises due to the system was 70.8%. Regression analysis of factors affecting the stages of behavioral change showed health interest(t=2.10, p<0.05), educational experience(t=2.81, p<0.01), knowledge score(t=2.260, p<0.05), and negative perception(t=2.13, p<0.05). The results of this study suggest that in order to increase the stage of behavioral change in GMO, it is necessary to raise interest in health and knowledge and have the correct perception through GMO education

본 연구에서는 채소와 과일 섭취 증진을 위한 영양교육이 행동변화단계의 진전에 따라 사회심리적요인에 변화를 초래하는지 파악하고자 초등학생을 대상으로 영양교육을 실시한 후 행동전단계를 두 단계로 나누어 이 두 단계 아동들의 채소와 과일 섭취의 장점과 단점에 대한 인지, 인지적 행위적 변화과정, 자아효능감의 수준 변화를 조사하였다. 충남 연기군의 한 초등학교 5학년 아동 71명에 대한 설문 조사에 의해 행동전단계 (고려전, 고려, 준비)로 분류된 47명을 대상으로 2007년 11월 19일부터 12월 24일까지 6주 동안 채소와 과일섭취 영양교육을 실시하고 교육전과 후에 사회심리적요인의 수준을 설문지법에 의해 조사하였다. 1) 영양교육 후 채소섭취의 장점에 대한 인지도 점수는 고려전단계나 고려 및 준비단계에 속한 대상자 모두에서 증가하였고, 단점에 대한 인지도 점수는 두 단계 모두에서 감소하였다. 그러나 과일섭취에 있어서는 장점에 대한 인지도 점수에서는 고려전단계와 고려 및 준비단계 모두에서 교육 후 변화가 없었으나, 단점에 대한 인지도 점수는 고려전 단계에 속한 대상자에서만 유의적인 감소가 나타났다 (p < 0.01). 채소섭취에 대한 장점과 단점에 대한 인지 개선 영양교육은 두 단계 모두에서 효과적이었다. 2) 영양교육 후 채소섭취의 인지적 변화과정에서는 고려전단계의 대상자에서 의식향상 (p < 0.001)점수가 증가되었고, 고려 및 준비단계에 속한 대상자에서는 걱정해소 (p < 0.01), 자기재진단 (p < 0.05), 환경재평가 (p < 0.01), 사회규범변화(p < 0.05) 등 여러 변수의 점수가 증가하였다. 과일섭취의 인지적 변화과정에서는 고려전단계에 있는 대상자에서 환경재평가 (p < 0.01)점수의 증가를 나타내었고, 고려 및 준비단계에서는 변화를 보인 변수가 없었다. 채소와 과일섭취의 행위적 변화과정에서는 모두 변화가 없었다. 3) 영양교육 후 채소섭취에 관한 자아효능감은 고려전단계에 있는 대상자에서 '채소를 보이는 곳에 둔다' (p < 0.01)와 '혼자 채소를 먹을 때 권장섭취 횟수만큼 먹을 수 있다' (p < 0.01). '채소 먹을 시간을 낼 수 있다' (p < 0.05)에서 증가를 나타내었다. 고려 및 준비단계에서는 고려전단계에서 나타난 '혼자 채소를 먹을 때 권장섭취 횟수만큼 먹을 수 있다' (p < 0.01)와 '채소 먹을 시간을 낼 수 있다' (p < 0.01)의 항목을 포함하여 '다양한 종류의 채소를 살 수 있다' (p < 0.01)에서 교육 후에 자아효능감이 높아졌다. 즉 채소섭취의 행동변화단계가 높아질수록 자아효능감의 수준이 성숙됨을 보였다. 과일섭취에 대해서는 영양교육 후 고려전단계에 속한 대상자에서 '과일을 보이는 곳에 둔다'의 자아효능감의 점수가 증가되었다 (p < 0.05). 이상의 연구결과에서 영양교육 후 행동전단계에 있는 아동들의 행동변화단계의 진전이 일어났고, 고려전단계와 고려 및 준비단계에서 모두 사회심리적요인의 수준이 높아졌으나 두 단계 간에는 교육효과의 유의적인 차이가 없었다. 과일에 비해 채소섭취와 관련된 사회심리적요인에서 교육 효과가 더 크게 나타났으며, 사회심리적요인들 중에서 판단 균형의 단점에 대한 인지도, 인지적 변화과정, 자아효능감이 영양교육의 평가지표로 사용될 수 있는 가능성을 보였다.

This study was carried out to assess the perception of decisional balance of Korean subjects about 4 health behaviors and to identify the influencing factor of decisional balance for exercise acquisition, smoking cessation, mammography screening and Kegel's exercise acquisition. All are representative health behaviors nurses can intervene in Korea based on the Transtheoretical model. Convenient samples of 2,484 subjects (191; exercise, 169; smoking cessation, 1903; mammography screening and 221; Kegel's exercise) were selected from cities and counties over 9 provinces throughout Korea, and the data was collected from January 1, 1999 to February 29, 2000. The research instrument were the Decisional Balance Measure for Exercise (Marcus & Owen., 1992), Smoking Cessation (Velicer et al., 1985), Mammography Screening (Rakowski et al.,1992) and Kegel Exercise (Lim, 1999) and Stage of Change Measure for Exercise (Marcus et al, 1992), Smoking Cessation (DiClemente et al., 1991), Mammography Screening (Rakowski et al.,1992) and Kegel's Exercise (Lim, 1999). The data was analyzed by the SAS Program. The results are as follows; 1. According to the stage of change measure, 2,484 subjects were distributed in each stage of change for four health behaviors: 1,233 subjects (49.8%), 745 subjects (30.2%), 113 subjects (4.7%), 156 subjects (6.5%), and 216 (8.7%) belonged to the pre- contemplation stage, contemplation stage, preparation stage, action stage and maintenance stage. They were all series of stages of change in their efforts to do health behavior. 2. Factor analysis identified 3 factors (1 of Pros, 2 of Cons) for the exercise, 4 factors for smoking cessation (2 of Pros, 2 of Cons), 2 factors (1 of Pros, 1 of Cons) for the mammogram screening and 2 factors (1 of Pros, 1 of Cons) for Kegel's exercise of decisional balance. 3. The analysis of variance and multiple comparison analysis showed that for all 4 samples, the Cons of changing the problem behaviors outweighed the Pros for subjects who were in the pre- contemplation stage, The opposite was true for subjects in action and maintenance stage. 4. Through the discriminant analysis, it was found that one factor of Pros for exercise, one factor of Cons for smoking cessation, 1 factor of Cons for mammogram screening and one factor of Cons for Kegel's exercise were the more influencing factors, than others in discriminating the stages of change. Results are consistent with the applications of the Transtheoretical model, which have been used to understand how people change health behaviors. This results provide some evidence that subject's report of his/her health behavior corresponds to beliefs about usefulness of related health behaviors. The results of this study have implications for patients' health education and health intervention strategies. The findings of this study give useful information for nursing educators for 4 health behaviors, especially the factors relating to decision making in the different stages of change.

This study was made to analyze the condition and the needs of nutrition education considering the different stage of nutrition education recognized by the dietitian in industrial area. 165 female dietitian were surveyed by questionnaire and they were divided into 4 groups according to the different recognition stages of nutrition education: Pre-contemplation(PC) 4.8%, Contemplation(CO) 46.7%, Preparation(PR) 22.4%, Action & Maintenance phase(AM) 26.1%. For statistical analysis, SAS(Ver.8.1. for Window) was used to find out the distribution related with nutrition education and to calculate the scores of mean and standard deviation. General characteristics of the subjects are about 20 years old(71.5%), single(69.7%), careers over 5 years(40%) and university graduates(73.9%). The number of meals(p<0.05) and the employment status(p<0.05) were significantly different according to the recognized stage of nutrition education. The practice of nutrition education was different depending on the dietitian in the industry. Many of the factory dietitian were in pre-contemplation stage(87.5%), however, those in the office and service area were more in Action & Maintenance stage(27.9%). In the industrial area, just 26.1% of dietitian operated the nutrition education and most did not due to the work overload and insufficient support of staff(73.3%). The frequency for the most effective nutrition education was once a month(61.2%). The contents for desirable nutrition education were in the order of 'eating habits'(36.1%), 'relation with the daily life'(23.5%), 'food hygiene' (21.7%), 'nutrition knowledge'(9.7%), and 'disease prevention'(9%). In operating nutrition education, dietitian had concerns about 'insufficient support of staff', 'shortage of teaching materials' and 'lack of time'. And, the dietitian who were with lower recognition stage of nutrition education(P<0.05) concerned more about the insufficient educational contents. In conclusion, dietitian in the industry highly recognized the need of nutrition education, but it was so difficult to practice. For more programs and various materials should be developed, and the staff's perception, the view of dietitian and the meal service should be changed, too. For the health improvement of industrial workers, it would be necessary to proclaim the importance of nutrition education nationwide.

The paper comments on the contribution of Oscar Salemink on his personal intellectual journal from Vietnam to Europe and back again. This then leads to the contemplation of the construction of Southeast Asia as a "place" or "locality", early preoccupations within the region of the national dimension. And more recent developments in universities in Singapore, examining the continuing perceptions of Southeast Asia as a region and Singapore as its "gateway", and the increasing interest in "connectivities" and transnational relations between the region and other parts of Asia and the wider world.

A purpose of this study is to comprehend a concept of 'Open Space', realization of a deconstruction, presented in his works, based on a deconstruction and surrealism Coop Himmelblau's philosophical contemplation and to look into how this concept is interpreted in spaces. A concept of 'Open Space' is functioned as not a singular meaning but a multiple meaning accompanied with other formative ingredient and contemplation, scientific paradigm and a realation with a surroundings. The concept of 'Open Space' in their architentural space is applied. First, the space openness that represents to the extreme a concept 'Open Space', as a 3D designing ways that demolishes a structure and outgrows an ex siting thinking pattern, represents multiple grade spaces and an anti-gravity space. In a material, using glass and iron provides a spacial transparency and through this, visibly liberal sense that an interior and exterior is felt as an unification. Second, an non-expressive box pattern repulses to a spatial rank nature, outgrowing an uniform geometrical system, through demolishing a geometrical system, an edge and fold pattern. This is, as an anti-gravity, dynamic a typical structure, outgrowing an orthogonal system, interpreted as a composite meaning without division in spatial area. Third, the collage is used to represent a complexity and pluralism in representing 'Open space'. The collage that forms a image through combining a fragmentary elements into being a space change, composite constitution and spatial amusement. Thus, It is worthwhile to study how the collage that forms a diverse shape will be developed making what impact as an age and surroundings changed. As we contemplate in former part, Coop Himmelblou has deployed 'deconstruction beyond deconstruction' realm as just their midterm concept in their works like the words 'The architecture must climb', the deconstructive architect. A studying for their works reflecting the 'Open Space' concept based on deconstruction must be lasted and this enables us to comprehend space concept containing an architecture and interior design.
