Purpose: The purpose of this study was to identify and understand the self-directed learning patterns of nurses. Q methodology was used to collect the data. Method: For the research method, 43 Q-statements were collected through individual interviews and a review of related literature. The 43 Q-statements were classified by the 34 participants in the study and the data was analyzed by the PC-QUANL program with principal component analysis. Result: There were 4 different patterns of self-directed learning classified as follows : Nurses in Type I the Future Provision Type, studied to promote their own professional development and leadership qualities for the future. Nurses in Type II, the Learning Passion Type, enjoyed learning something new and had a strong learning desire. Nurses in Type III, the Self-reflective Type, continuously evaluated self and their own practice by introspection. Nurses in Type IV, the Accompanying Companion Type, studies with companion support and maintained a collaborative relationship rather than competing with each other. Conclusion: This study explains and allows us to understand self-directed learning in nurses. Thus this study will contribute to building a theoretical base for the development of a self-directed learning model in nursing practice.

Purpose: This study is used to investigate and understand types of meaning in life of matriarch. Methods: This study is based on a Q-methodological approach. Thirty nine statements concerning meaning in life were selected. Twenty seven women were chosen as a subject group for this study. Their opinions were shown in 39 statements divided into 9 scales by forced distribution. Results: TypeI was named "self-transcendental and future- oriented types". In this types a one pursued attitudinal value by religion. Type II was named "Realistic and responsibility fulfilling types". This type pursued creative and experiential value. Type III was named "Encounter and relationship oriented type". This types pursued experiential value. Type IV was named "Realistic self-actualizing type". This types pursued creative value. Type V was named "Altruistic and commitmental types". This type pursued creative, experiential, and attitudinal value. Conclusion: Considering the structure of finding the meaning in life of matriarchs, all types had responsibility and self-control in their lives and lived for present however, only typeI lived for the future. It seem necessary to understand each matriarchs meaning in life and nursing needs to develop appropriate nursing interventions based on the type matriarch she is.

This paper introduces a serious game called freCman developed for C programming language beginners. Since key words, syntax, and programming structure of C programming language are unfamiliar for them, they feel uneasy and have many difficulties to study. We developed three games such as shooting star C, finding hidden errors, unscrambling C codes through which C beginners can study C language easily. Also we developed CTS(Code to Speech) which speeches C source codes like English statements so that C beginners can be familiar with C key words and statements. To prove effectiveness of the freCman, some experiments have been conducted with C language beginners. Experiment results show that the freCman helps beginners studying C programming language much.

One of the most common problems encountered in the automatic translation of FORTRAN source code to VECTRAN is the occurrence of conditional transfer of control within loops. Transfers of control create control dependencies, in which the execution of a statement is dependent on the value of a variable in another statement. In this paper I propose algorithms involve an attempt to convert statements in the loop into conditional assignment statements that can be easily analyzed for data dependency, and this paper presents a simplification method for conditional assignment statement. Especially, I propose not only a method for simplifying boolean functions but extended method for n-state functions.

Typical confidence intervals for a mean or mean residual life (MRL) are centered about the mean or mean residual life. We discuss novel confidence intervals that produce statements like "we are 95% confident that the MRL function, e(t), is greater than a prespecified $\mu_o$ for all t in the interval [0, $\hat{\theta})$)" where $\hat{\theta}$ is determined from the sample data, confidence level, and $\mu_o$. Also, we can have statements like 'we are 95% confident that the MRL of population 1, namely $e_1$(t), is greater than the MRL of population 2, $e_2$(t), for all t in the interval [0, $\hat{\theta}$)" where $\hat{\theta}$ is determined from the sample data and confidence level. We illustrate these one and two sample confidence intervals on internal bonds (tensile strengths) for an important modem engineered wood product, called medium density fiberboard (MDF), used internationally.

Scientific observation has been recognized as one of the fundamental aspects in scientific inquiry. However, more detailed discussions and practical guides for teachers' and students' understanding about the nature of scientific observation have not been conducted. Therefore, based on literature reviews, we described the nature of theory-laden scientific observation as 11 detailed statements. Using theses statements, we investigated science teachers' and students' recognition of each statement. According to results, certain aspects of theory-laden scientific observation were determined as important aspects to be considered for science teachers' in-service programs or for students' learning activities in understanding the nature of science.

Purpose: This study was done to identify types of subjective perception of their disease by adolescents who have insulin dependent diabetes mellitus (IDDM) in order to better understand these adolescents and to determine effective nursing interventions. Method: Q-methodology was used in this study. The 36 Q-statements were selected through a literature review and in-depth interviews with participants. Data were collected from a 33 P-sample by sorting the 36 Q-statements into a 9 point standard. The data were analyzed using the PC QUANL program. Results: Five types of perception were identified: Type 1 being a recipient and having a will to cope with the disease, Type 2, seeking support from others, Type 3, emotional and negative coping, Type 4, pursuing own beliefs but with conflict at the same time, and Type 5 feeling under heavy pressure as their condition made them feel insecure, and they felt sorry to their families. Conclusion: The findings of the study are expected to contribute to improving clinical practices by helping nurses have a broader understanding of adolescents with IDDM, and exploring ideal nursing interventions.

This study was designed to identify school health nurses' attitudes toward sex education through a Q-methodological approach. Research was done from Apr. 3, 1995 to Oct. 15, 1995. A final Q-sample was selected to 37 statements out of initial 128 statements after consultation from counselors, educators and writers related to sex education. The P -sample was consisted with 32 school health nurses in Chonbuk province. The collected data were analyzed by Quanal program on PC. The results of the study were as follows: School health nurses are categorized into 6 types. The first type, receiving type with cognition deficiency about general learning objectives of sex education were consisted with 4 subjects. The second type, valuing type with cognition deficiency about general learning objectives of sex education were consisted with 6 subjects. The third type, adopting behavior type with cognition deficiency about specific learning objectives of sex education were consisted with 5 subjects. The fourth type, receiving type with cognition deficiency about specific learning objectives of sex education were consisted with 5 subjects. The fifth type, making sense of information type with cognition deficiency about specific learning objectives of sex education were consisted with 5 subjects. The sixth type, adopting behavior type with cognition deficiency about general learning objectives of sex education were consisted with 7 subjects. As a result of this study, we may realize necessity of prepared sex educators. Sex the educators must be fully cognitive and affective toward sex education before practicing sex education.

Software evolution is an ongoing process carried out with the aim of extending base applications either for adding new functionalities or for adapting software to changing environments. This brings about the need for estimating and determining the overall impact of changes to a software system. In the last few decades many such change/impact analysis techniques have been developed to identify consequences of making changes to software systems. In this paper we propose a new approach of estimating change/impact analysis by classifying change based on type of change classification e.g. (a) nature and (b) extent of change propagation. The impact set produced consists of two dimensions of information: (a) statements affected by change propagation and (b) percentage i.e. statements affected in each category and involving the overall system. We also propose an algorithm for classifying the type of change. To establish confidence in effectiveness and efficiency we illustrate this technique with the help of an example. Results of our analysis are promising towards achieving the aim of the proposed endeavor to enhance change classification. The proposed dynamic technique for estimating impact sets and their percentage of impact will help software maintainers in performing selective regression testing by analyzing impact sets regarding the nature of change and change dependency.

The purpose of this study was to provide fundamental data and implication for forming desirable viewpoint of mathematics lesson critique and for improvement of expertise in lesson by compare and analyze the viewpoint of mathematics lesson critique of pre-service and in-service teachers. For the achievement of the purpose, The lesson critique materials of each 25 pre-service and in-service mathematics teachers were collected and arranged, and compare and analyze the viewpoint of mathematics lesson critique of pre-service and in-service teachers by using the standard for analyzing viewpoint of lesson critique composed of two categories, five main codes and 18 sub codes. The results of this study, both pre-service and in-service teachers have tendency for criticising lesson focusing on the practice rather than plan of lesson and both pre-service and in-service teachers showed evaluative reaction in most of critical statements and used positive ones rather than negative ones. The only pre-service teachers, though minor of them, showed non-evaluative reaction in criticising class and most of the statements were just description and explanation without any their own judgement for the scenes and activities of lessons and most of pre-service teachers have tendency to include reflection and introspection for their own class in lesson critique.
