Purpose: Loneliness is an extremely subjective experience that is influenced by life experiences and circumstances. This study attempted to provide basic data for the development of nursing intervention strategies to understand the concept of loneliness and to reduce loneliness on various topics. Methods: The research analysis method is based on the framework of concept analysis proposed by Walker and Avant (1988). Results: The results of this study are as follows: 1) Self-alienation 2) Isolation of human beings 3) Psychological damage reaction 4) Pain 5) Loneliness is the loss of a comfortable "frame". The prerequisites can be divided into personal characteristics and situational characteristics. Empirical criteria include intimate others, lack of social relationships or problems, family and friendship, belonging, recognition or expression of loneliness, emotional state changes and changes in health behavior, and physical symptoms. Conclusions: Loneliness is an important indicator of well-being and a cause of physical and mental illnesses, so nurses facing various subjects should be able to recognize the signs and symptoms of loneliness. By promoting and sustaining their interest, they should be able to enjoy lonely people.

From the observations of dietary self-selection by growing pullets, step-up protein or reverse protein and single-stage low protein pullet feeding systems were developed. They offered another pullet feeding concept that appears to control the body weight effectively and to reduce the consumption of feed and nutrients without impairment of subsequent laying performance. It is obvious from the feed and nutrient consumption pattern of layers fed diets for self-selection of energy, protein and calcium that they have a daily cyclic requirement rather than a constant requirement for nutrients. It seems that a practical self-selective feeding system is needed to meet the daily cyclic requirement for nutrients without consuming an excess of energy and protein at certain times of the day as compared to the complete or single diet where layers have to consume extra energy and protein in the afternoon when they have a specific appetite mainly for calcium.

Modern society requires people with practical knowledge that is able to recognize actual problems in the complex reality and solve the problems. Due to that reason, the 7th National Curriculum aims to basically cultivate ability adaptable to information-oriented global age by maximizing students' individuality and creativity. However, as existing education is hard to improve creativity, logical thinking, information processing skills, and problem-solving ability in the information-oriented age, self-directed learning is getting highlighted. Therefore, this study aimed to look into how learner-oriented IPER for self-directed learning and problem-based learning(PBL) in middle school science affected academic achievement of science and self-directed learning characteristics. As the results of the study are as follows. First, as the result of pre-and post-test to compare and analyze the effects of IPER instruction model and PBL instruction model on learners' academic achievement increase, it showed that the class with IPER instruction model was more effective. Second, as the result of pre-and post-test to compare and analyze the effects of IPER instruction model and PBL instruction model on self-directed learning characters, IPER was more effective than PBL overall, and among sub-areas, 'openness', 'self-concept', 'initiative', 'future-oriented self-understanding', and 'self-evaluation' were more effective in IPER while 'creativity' was more effective in PBL. However, among sub-areas 'responsibility' and 'learning enthusiasm' didn't show statistically significant difference. Third, the results of the post-survey to compare and analyze learners' perception regarding the application of IPER instruction model and PBL instruction model, the two models were positively affective. In addition, as the result of comparing the two models, IPER was more positive than PBL.

With accumulated nursing research results from older adults, refined middle range nursing theories are evolving in gerontological nursing area. Three middle range nursing theories and framework were reviewed and described. Life transition framework for older adults were developed through research related to relocation and other transitions taken place in later life. Self-efficacy exercise model was developed by extensive research related to rehabilitation of older adults based on self efficacy expectations and outcome expectations concept from social cognition theory. Need-Driven dementia-compromised Behavior (NDB) model was developed by a group of nursing scholars studying dysfunctional behaviors of demented older adults. All of these theories are approaching to practice theory by developing interventions and nursing therapeutics. There are more needs to develop theories for specific gerontological nursing phenomena such as delirium, end of life and self integrity.

Diabetes mellitus, a universal and prevalent chronic disease, is projected to be one of the most formidable worldwide health problems in the 21st century. For those living with diabetes, there is a need for self-care skills to manage a complex medical regimen. Self-efficacy which refers to one's belief in his/her capability to monitor and perform the daily activities required to manage diabetes has be found to be related to self-care. The concept of self-efficacy comes from social cognitive theory which maintains that cognitive mechanism mediate the performance of behavior. The literature cites several research studies which show a strong relationship between self-efficacy and self-care behavior. Meta-analysis is a technique that enables systematic review and quantitative integration of the results from multiple primary studies that are relevant to a particular research question. Therefore, this study was done using meta-analysis to quantitatively integrate the results of independent research studies to obtain numerical estimates of the overall effect of a self-efficacy with diabetic patient on self-care behaviors. The research proceeded in three stages : 1) literature search and retrieval of studies in which self-efficacy was related to self-care, 2) coding, and 3) calculation of mean effect size and data analysis. Seventeen studies which met the research criteria included study population of adults with diabetes, measures of self-care and measures of self-efficacy as a predictive variable. Computation of effect size was done on DSTAT which is a statistical computer program specifically designed for meta-analysis. To determine the effect of self-efficacy on self-care practice homogeneity tests were conducted. Pooled effect size estimates, to determine the best subvariable for composite variables, metabolic control variables and component of self-efficacy and self-care, indicated that the effect of self-efficacy composite on self-care composite was moderate to large. The weighted mean effect size of self-efficacy composite and self-care composite were ＋.76 and the confidence interval was from ＋.66 to ＋.86 with the number of subjects being 1,545. The total for this meta-analysis result showed that the weighted mean effect sizes ranged from ＋.70 to ＋1.81 which indicates a large effect. But since reliabilities of the instruments in the primary studies were low or not stated, caution must be applied in unconditionally accepting the results from these effect sizes. Meta-analysis is a useful took for clarifying the status of knowledge development and guiding decision making about future research and this study confirmed that there is a relationship between self-efficacy and self-care in patients with diabetes. It, thus, provides support for nurses to promote self-efficacy in their patients. While most of the studies included in this meta-analysis used social cognitive theory as a framework for the study, some studies use Fishbein & Ajzen's attitude model as a model for active self-care. Future research is needed to more fully define the concept of self-care and to determine what it is that makes patients feel competent in their self-care activities. The results of this study showed that self-efficacy can promote self-care. Future research is needed with experimental design to determine nursing interventions that will increase self-efficacy.

A mortar system is able to be fired more rapidly and concentratedly than other field gun systems. A mortar system can be easily manufactured because of its simple structure. It has also been supporting for the fire power of infantry because it can be carried conveniently. But a mortar system has demerits that are the limited firing range, poor accuracy and uncomfortable operability. Korean army plan to be operated rapidly and enlarge battle field in the near future. So weapon systems of Korean army must have longer firing range, automatic laying function and precision firing capability. This study suggests efficient developing concept of 120mm self-propelled mortar system through surveying the technical readiness level of current R&D and manufacturing ability.

Purpose: This study systematically examined the concept of digital selling readiness of salespeople. Additionally, this study empirically confirms the sequential mediating roles of digital literacy and salesperson self-efficacy in the impact of digital selling readiness on customer-oriented behavior. Research design, data, and methodology: We collected data from salespeople at a Bank and Financial Service firm in South Korea. A total of 254 salespeople were invited to participate, with 154 surveys returned. After removing the questionnaires with missing values, 150 complete surveys were employed for the analysis. Results: The empirical analysis indicates that digital selling readiness positively affects digital literacy. Digital literacy, in turn, is positively associated with self-efficacy, leading to increased customer-oriented behaviors among salespersons. This study also confirms the sequential mediating effects of digital literacy and self-efficacy in the impact of salespeople's digital selling readiness on customer-oriented behavior. Conclusions: Our research deepens the understanding of how digital selling readiness fosters customer-oriented behavior through the sequential mediating effects of digital literacy and self-efficacy. This study extends the previous model by sequentially involving digital literacy and self-efficacy to better understand the psychological processes of digital selling. The results highlight the role of digital selling readiness in preparing salespeople for digital sales.

Purpose: The purpose of this study was to review the concept of Mother-Child Interaction (MCI) as well as its theoretical model and measurement methods. Methods: A review of related theories and research was done to identify the concept and present status of MCI measuring techniques. Results: The concept of MCI contains the two aspect of attachment and child rearing. MCI is unique in that it includes a dyadic process. The concept of MCI was developed based on attachment theory, Barnard's theory, and the goodness of fit model, MCI involves sensitivity, responsiveness, reciprocity, contingency, mutual satisfaction, and child developmental stimulation including positive and negative affection. Most instruments involved observation, especially in structured situations, and most were developed for mother-infant interaction. Conclusion: MCI is a reciprocal, goal-oriented partnership process and is an ongoing process during childhood. Instruments for measuring MCI for preschoolers as well as appropriate self-reporting instruments need to be developed for wide use in practice and in research.

Purpose: The purpose of this study was to define and clarify the concept of political competence for nurses. Methods: A hybrid model method was used to investigate the dimensions, attributes, and definitions of the concept. In the theoretical stage of the study, literature on nursing, politics, and other discipline were reviewed. In the fieldwork stage, individual in-depth interviews and focus groups interviews were conducted with politically seasoned experts or activists who had an understanding of the concept of political competence for extensive descriptions in nursing and field of health care. Results: The concept of political competence was represented in four dimensions as political knowledge, political efficacy, political interaction, and political activity. In the political knowledge dimension, there were three attributes, namely, political knowledge, political information and systematic analysis ability. The political efficacy dimension had three attributes of internal political efficacy, external political efficacy, and self-pride of nursing profession. The political interaction dimension had three attributes of organizations and community service, networking, and persuasive power. The political activity dimension had six attributes of political leadership, political expression, assertive behavior, political advocacy, political participation, and policy intervention. Conclusion: This concept development might provide a basic understanding of developing a measurement tool and for constructing a theory promoting nurses' political competence.
