This study aims to identify unique small group norms and their influence on the process of constructing a scientific model. We developed instructional materials for the construction of a model of blood flow in the heart and conducted research on eighth-grade students from one middle school. We randomly selected 10 small groups, and videotaped and recorded their dialogues and behaviors. The data was categorized according to the types of interaction and then analyzed to investigate the characteristics of group norms and models in one or two representative groups for each type. The results show that the types of interaction, the quality of the group models, and the group norms were different in each group. Even though one teacher guided students through the same task in the inquiry context, each group revealed different patterns of discourse and behavior, which were based on norms of cognitive responsibility, the need for justification, participation, and membership. With the exception of one group, there was little cognitive responsibility and justification for students' opinions. Ultimately, these norms influenced the model construction of small groups. A group that forms norms to encourage the active participation and justify members' opinions with cognitive responsibility was encouraged to do inferential thinking and construct a group model close to the target model. This study has instructional implications for the establishment of a classroom environment that facilitates learning through small group activities.

This study investigated the effects of song discussion on depression and rehabilitation motivation in stroke patients. Older adults with chronic stroke participated in this study: nine for the experimental group and eight for the control group. The experimental group was divided into three subgroups and participated in 12 sessions over 6 weeks. Target lyrics were selected by the investigator among popular songs from the participants' young adulthood. The song-based discussion was facilitated to address issues targeted at supportive, insight-focused, or reconstructive stage. The control group was provided with delayed intervention. At pre and posttest, the short form of Geriatric Depression Scale and the Rehabilitation Motivation Scale were measured. The experimental group showed significantly decreased depression and significantly increased rehabilitation motivation (p < .01), while the control group showed no significant changes. Positive changes were also observed in all subcategories of rehabilitation motivation in the experimental group, particularly in significantly increased task-oriented motivation and decreased amotivation. This study suggests that song discussion will be effectively applied in rehabilitative settings to address psychological issues of older adults with stroke.

A buffer is the major component of a high level radioactive waste repository. Due to their thermal conductivity and low permeability, bentonites have been considered as a key component of a buffer system in most countries. The deep geological condition generates ground water inflow and results in swelling pressure in the buffer and backfill. Investigation of swelling pressure of bentonite buffer is an important task for the safe disposal system. The swelling pressure that can be critical is affected by mechanical and hydro properties of the system. Therefore, in this study, a sensitivity analysis was conducted to examine the effect of hydro-mechanical (HM) behaviors in the MX-80 bentonite. Based on the results of the swelling pressure generation with HM model parameters, a coupled HM analysis of an unsaturated buffer and backfill in a deep geological repository was also carried out to investigate the major factor of the swelling pressure generation.

Various assessment indexes have been developed and utilized to evaluate the driver workload. However, existing workload assessment indexes do not fully reflect driving habits and driving patterns of individual drivers. In addition, there exists significant differences in the amount of workload experienced by a driver and the ability to overcome the driver's workload. To overcome these limitations associated with existing indexes, this study has developed a novel workload assessment index to reflect an individual driver's driving pattern. An average of the absolute values of the steering velocity for each driver are set as a threshold value in order to reflect the driving patterns of individual drivers. Further, the sum of the areas of the steering velocities exceeding the threshold value, which is defined as erratic steering area (ESA) in this study, was quantified. The developed ESA index is applied in evaluating the driver workload of manually driven vehicles in automated vehicle platooning environments. Driving simulation experiments are conducted to collect drivers' responsive behavior data which are used for exploring the relationship between the NASA-TLX score and the ESA by the correlation analysis. As a result, ESA is found to have the greatest correlation with the NASA-TLX score among the various driver workload evaluation indexes in the lane change scenario, confirming the usefulness of ESA.

The characteristics of Hyeonmoyangcheo-ism (wise mother, good wife) in the 1950s, which were observed through the girls' school curriculums and homekeeping textbooks, were arranged as follows. Firstly, Hyeonmoyangcheo-ism in homekeeping textbooks in the 1950s stressed the modern housewife. The Confucianwomen's virtues, such as submissiveness, faithfulness and samjongjido (obedience to father, husband and son), that were in girls' moral training and home management textbooks during the Japanese imperialism. This was a part of girls' education built on democracy and equality asserted by a new Korea, the 'modern nation'. Secondly, with the increasing demands for women's labor after the Korean War, women's occupations were reinforced and incorporated in homekeeping textbooks in the 1950s. Even though having a job was a secondary task to the role of a homemaker, the details of women's occupation illustrates the characteristics of Hyeonmoyangcheo-ism in this period of time. Thirdly, The resident practice program emphasized the tradition women's behavior along with the modern homemaker, the rational designer of homekeeping. This seems to have been reinforced from the criticism towards women based on Westernization after the Korean War.

As the service industry develops, service quality, customer satisfaction, and human resource management are considered priorities in modern management to maintain a company's growth. Therefore, understanding the strategic importance of service marketing is an essential task for modern companies. This study examined the relationship between the internal service quality of employees in the organization and customer orientation through organizational effectiveness. In the case of an airline, a service can be defined as an interaction between an external customer and an internal customer service provider. This interaction significantly affects the behavior and attitude of the employees. Based on the results, empowerment has a significant influence on the internal service quality, but it has no significant effect on customer orientation. As the relationship between department and employees improved, the more confident staff showed an improved ability to perform their work. Therefore, it is important that the organizational structure and the reporting system are as concise and clear as possible to allow employees to accurately recognize the authorities and responsibilities assigned to them and have autonomy and discretion in the framework.

M&S techniques are widely used as scientific means to systematically develop response plans to chemical and biological (CB) hazards. However, while the theoretical area of hazard dispersion modeling has achieved remarkable practical results, the operational analysis area to simulate CB hazard response plans is still in an early stage. This paper presents a model to simulate CB hazard response plans such as detection, protection, and decontamination. First, we present a possible way to display high-fidelity hazard dispersion in a combat simulation model, taking into account weather and terrain conditions. We then develop an improved vulnerability model of the combat simulation model, in order to simulate CB damage of combat simulation entities based on other casualty prediction techniques. In addition, we implement tactical behavior task models that simulate CB hazard response plans such as detection, reconnaissance, protection, and decontamination. Finally, we explore its feasibility by analyzing contamination detection effects by distributed CB detectors and decontamination effects according to the size of the {contaminated, decontamination} unit. We expect that the proposed model will be partially utilized in disaster prevention and simulation training area as well as analysis of combat effectiveness analysis of CB protection system and its operational concepts in the military area.

The aim of this study was to take the field manager's opinion about the dental hygiene student's competency. Study design was cross sectional contents analysis with the in-depth interviews. Twelve subjects were randomly selected in half an hour interview. They were signed there's own autograph on the informed consents. The contents of the qualitative interviews were divided into two parts: students' competency required for the field practice and the system of the field practice. The first part consisted of the attitude of the field's practice, how well has accomplished the job, and demanded requirements for the better performance. And the other part was made up of duration of practice, the number of students per institution and other opinion. The results showed that most of them have positive conception about student's competency. They mentioned that many students have 'enthusiastic behavior and attitude in task performance' and 'progressive attitude and mind in duty'. While 'lack of interest in practice and sociality', 'the arrogant demeanor in the fields', and 'passive behavior and attitude in the interpersonal relationship' should be avoided for excellent competency. It is required for dental hygiene students to write daily practice record and clarify their reasons to choose the institution for better performance. In addition, it should be considered to make concrete evaluation items and students and field managers should have mutual responsibility.

Health promotion has more comprehensive approaches in recent years. Nevertheless we accept the concept of health promotion differently, we are agree on that community is the most important field in health promotion which includes population at the aspect of health policy, individual skill and, environment. And there are a number of different approaches to health promotion. In them, 'population approaches' and 'high -risk group approaches' has the most different characteristics. 'Population approaches' is equally important or more important than 'individual approaches' for maintaining and promoting population health. Almost part of this article contents is the summary of the guideline and population strategy of health promotion in Korea, 1999 - 2005. Community based health promotion program should be reinforced, integrated, comprehensive, collaborative through efficiently utilizing community resources. Recent new orientation of community health program is integrated health program, we can find this orientation at Ottawa charter 1986. Comprehensive approaches with the determinant factors for health are essential task. Physical activity is a key health determinant. The population-health approach suggests that educating people about physical activity is not enough. Individual behavior changes are important too, but need to be balanced with strategies for environmental change. Population strategy with physical activity for health promotion should be developed through improving social and physical supportive environment, linking and integrating community resources between public and private sectors in national, regional and local level. Continuous public education and social marketing should be provided through collaborating with community physical activity organization, facilities, work-places and school for increasing concern of all the people of community about physical activity. Governments, agencies and citizens should held and participate to building movement. And the strategy that various 'active for life' program should be developed, delivered, maintained and reinforced continuously. Basically, adequate and sufficient financing, developing human resources, policies and legislation would be provided and supported fully too. At last, research development and knowledge exchange are required domestically and internationally. In Korea, we had classified the category of strategic priority of physical activity programs by environmental support, life-course approach, high-risk group approach and disease group approach for physical activity program based on community health center. Community based core programs for physical activity that includes infrastructure building and establishment of supporting environment, community campaign, health promotion education and public service announcement, physical activity programs for elderly and obesity, exercise prescription program.
