Purpose: This in vitro study aimed to evaluate the clinical acceptability of precision of fit of the support thickness of Co-Cr alloy copings fabricated using selective laser melting (SLM). Methods: Thirty dental stone models of maxillary left molar abutments were manufactured, images were taken using a scanner, and a computer-aided design program was used to design the form of a conventional metal ceramic crown coping. Overall, 30 single copings were made from Co-Cr alloy using SLM and divided into three support radius groups (0.1, 0.25, and 0.35 mm) of 10 for each. Digitized data were superimposed with three-dimensional inspection software to quantitatively obtain the machinability of a ceramic crown coping, and visual differences were confirmed using a color map. The root mean square values of the ceramic crown coping group were statistically analyzed using one-way analysis of variance (α=0.05). Results: The precision of fit was superior with 0.25 mm compared with 0.1 mm and 0.35 mm, and the results exhibited significant differences (p<0.05). All specimens showed that various support thicknesses did not exceed the clinically permitted value of 120 ㎛, which mean that more than 0.1 mm and 0.35 mm of support radius for SLM was adequate. Conclusion: The support thickness of Co-Cr alloy restoration fabricated using SLM is shown to affect the adaptation.

A phenomenological methodology was used to identify the life of children living with alcoholic parents. Nine adolescents participated in the in-depth interviews, done between October and December 2001. The Colaizzi's method was used for data analysis. The results of this study are as follows. One theme and thirteen meanings were identified, The one theme is Paradoxical Coping in Life. The meanings are obsessive behavior as a way to control father's behavior, always on the defensive due to anxiety and tension, being afraid of life alone due to paranoid thoughts, contradictory expectations about father's drinking behavior due to life with chronic tension, stress becoming familiar and life being boring and tendious without stimulation, life that is fake and filled with misinterpretations about reality, affection sought from others due to loneliness, compensatory life within peer group, negative expectation about the future due to negative experiences, controling others to protect ego, denial of real emotion to protect self from hurt, life of regretting self, and strong need for approval from others. The results of this study can provide a foundation for the development of programs for children of alcohol dependent parents.

Purpose: The purpose of this study was to identify the factors influencing suicidal ideation in male baby boomers. Methods: This was a descriptive survey study. Data were collected from December, 2012 to June, 2013 from 194 participants. The instruments used included a suicidal ideation questionnaire, somatic symptoms scale, spiritual well-being scale, communication with spouse scale, and social support scale. Data were analyzed using t-test, one-way ANOVA, Pearson's correlation coefficient, and stepwise multiple regression analysis. Results: Suicidal ideation was influenced by learning needs on psychological coping, somatic symptoms, existential spiritual well-being, and communication with spouse. Somatic symptoms (${\beta}$=.39, p<.001), existential spiritual well-being (${\beta}$=-.20, p=.009), learning needs on psychological coping (${\beta}$=.16, p=.008), and communication with spouse (${\beta}$=-.15, p=.031) accounted for 37% regarding suicidal ideation in male baby boomers. Conclusion: We found an association of lower levels of existential spiritual well-being and communication with spouse, higher suicidal ideation. Higher suicidal ideation was also observed in people who had no learning needs on psychological coping compared with those who had. Based on the outcomes of this study, design of an intervention program that emphasizes existential spiritual well-being and communication with spouse is necessary in order to decrease suicidal ideation in male baby boomers.

인터넷 환경이 급속도로 변화하면서, 관리해야하는 내부 네트워크의 규모도 커지게 되었다. 이에 따라서 보안의 중요성에 대한 인식이 확대되고, 내부 정보의 보호를 위해 많은 보안 시스템이 도입되었다. 그러나 분산된 보안 시스템들은 각각이 다른 사용자 인터페이스로 인하여 효율적인 보안관리가 어려울 뿐만 아니라 장애발생 시 일괄적이고 즉각적인 대처가 어렵고 관리 인력의 비대화를 야기 시킨다. 따라서 본 논문에서는 시스템의 일관적이고 통합적인 관리를 위해서 중앙에서 각 시스템의 상태를 파악하고 관리하는 통합보안관리시스템을 제안한다. 제안하는 통합보안관리시스템은 다중 에이전트를 이용함으로써 장애 대처가 빠르며, 각각의 보안 솔루션들에 대한 취약점을 최소화할 수 있고, 분산된 보안 시스템들을 일괄적으로 통제 및 관리할 수 있다.

Purpose: This study aimed to explore the difficulties and coping that advanced practice nurses (APNs) experience in home health nursing field. Methods: The participants were 12 APNs who had experience in home health nursing for over 5 years. Data were collected through two focus group interviews between August and September, 2017. The results were analyzed using a qualitative content analysis. Results: Out of 10 sub-categories and 29 codes, 4 categories emerged: "crushed by the responsibilities as the only healthcare professional", "worn out by family who interfere with work", "anxiety about my safety being threatened" and "using self-learned know-hows". Conclusion: APNs face difficulties due to the environmental characteristics of the homes, the characteristics of chronically critically ill (CCI) patients and their families, and legal or systematical limitations when dealing with problems based on their personal competence. In order to ensure that professional nursing care is more readily provided to CCI patients through home health nursing services in local communities, it is imperative that support systems at the organizational and institutional levels be established in a systematic way to resolve the issues faced by APNs.

Purpose: This study was done to provide fundamental ontological understanding of caring and inquiring into the possibility of a caring practice in nursing based on existential phenomenology. Methods: According to Heidegger's existential phenomenology, caring has been interpreted as a fundamental ontological basis for caring practice in nursing. Further, based on Merleau-Ponty's phenomenology, the meaning of the lived experience of illness and the way of caring practice have been described from the aspect of the existential involvement in the embodied life world. Results: Heidegger's phenomenology provided ontological thinking about caring, which is understood in a basic way as the possibility of human existence and dwelling in oneself in the confrontation of the illness experience. Merleau-Ponty's phenomenology offered a meaning of human existence according to bodily intention and situated freedom in the life world. This perspective of embodiment enables nurses to understand bodily experiences of patients and recovery of their bodily capacity in responding to the situation in caring practice. Conclusion: Existential phenomenology gives insight into fundamental reflection for caring attitude and practice in nursing. Existential phenomenological nursing research can provide descriptions and meaning of the lived experience of illness and a way of coping with the crisis of human existence in caring practice.

The purpose of study was : 1) to analyze the trend of research on the family with chronically ill children in Korea, 2) to suggest direction for future study on the family with chronically ill children, and contributing to the use of intervention in family nursing practice. Research studies on the family with chronically ill children were selected from the Korean Nusre, the Korean Nurses' Academic Society Journal, and from dissertations, which were conducted between 1975 and 1995. The total numbers of the studies were 35. These studies were analyzed for 1)time of publication or presentation, 2)research design, 3)characteristics of subjects, 4) type of chronic disease, 5)main concepts, 6)measurement tool, 7) the sis for a degree or nondegree, 8) result of correlational studies. The findings of the analysis were as follows : 1) The numbers of studies on the family with chronically ill children have increas rapidly the early 1990's. In research design, the numbers of survey research studies were the highest. Especially, the most frequently research design was the correlational survey. There were 19 correlational studies(25.7%) during the early 1990's. 2) The subjects in 16 studies(45.7%) were mother of chronically ill children and, in 8 studies (22.9% ) were their parents. 3) In most types of chronic diseases, there were 14 hematooncologic disease(32.6%) and 14 hadicapped children (32.6% ). 4) Frequently used research concepts were stress, degree of coping or way of coping, social support, parents' support, family functioning, intensity of family and family adaptation. 5) Acceding to the results of correlational studies, the more family stress was higher the more degree of coping, family functioning, intensity of family and degree of family adaption was lower. The more degree of social support was higher the more stress was lower and degree of coping, family functioning and intensity of family was higher. The more family functioning was higher the more intensity of family and family adaptation was higher. 6) 24 researches on the family with chronically ill children were done for a thesis for a degree and 11 were nondegree research studies. The following suggestions are made based on the above findings : 1) The pattern of these studies related to the family with chronically ill children in domain of Nursing need to be compared with trend in other domains. 2) More replicated research on the family with chronically ill children is needed to develop family nursing intervention and prove the effect of that and more qualitative research on the family with chronically ill children is needed to comprehensive indepth the family with chronically ill children. 3) Further research on the family with chronically ill children is needed to verify subjects and type of chronic disease, develop applicable measurement tools in Korea and identify relation between other concepts. 4) Family nursing researchers should make an effort to apply research result in various clinical settings and community settings, and try to carry out not only team research with clinical nurse but also other multidisciplinary researcher related to the family.
