Though super-highrise apartment buildings have become increasingly widespread, their negative effects on the residents have not been investigated sufficiently and practically in domestic situations. In particular, the foreign discussion on residential environment and the residents' health can not be applied domestically due to physical or cultural differences including physical residential space structure and life-style. Therefore, this research aims to investigate the inter-relationship between residence in super-highrise apartments and their residents' health, to reveal the problems which exist. for this purpose, a parental-response health evaluation - questionnaire on children's physical, emotional and behavioral characteristics was given to a total of 336 persons. The health of the children living in super-highrise apartments is evaluated to be good, and is related to what floor of the apartment building people live on. It is represented that the higher the story, the better the children's health. However, there is no meaningful difference according to various evaluation items including the frequency and type of disease, emotional health, behavioral characteristics, etc. Therefore, it cannot be said that children's health shows no meaningful differences depending on what floor they live on. The parents dwelling on higher floors of the building display a more careful educational attitude. This is because they feel anxious about the children's safety as shown by the fact they live on higher stories.

최근 주상복합형의 주거공간, 지하철, 대형쇼핑몰 등 건물내부가 복잡하고 대규모인 공간에서 머무르는 시간과 기회가 날로 증가하고 있다. 건물이 복잡할수록 건물 내에서 사람들이 원하는 목적지에 도착하기까지 보다 많은 시행착오를 겪으면서 이동하게 된다. 시행착오를 줄이고, 보다 빠르게 이동하기 위해서는 최단경로를 탐색하여 제공하는 시스템이 필요하게 된다. 이러한 대규모 공간 내에서의 최적이동경로에 대한 정보는 특히 화재나 정전, 테러위협과 같은 응급상황에서 더욱 필요로 하게 된다. 이에 본 연구에서는 Raster GIS기반의 데이터구조 상에서 $A^*$알고리즘을 사용한 최단경로 탐색기법을 비교, 분석하고자 한다. 평상시에는 건물내부에서의 위치 이동시에 필요한 최단 경로를 제공하고, 응급상황에서는 탐색시간을 최소화하여 대피 경로를 제공하는 방안을 제시하였으며, 이를 캠퍼스 건물을 이용하여 예시하였다.

A top priority in the design of underwater vehicle is to guarantee the dependability of the electric system because failure of the electrical power supply system is directly related to the life of the passengers. In this paper, we present four kinds of alternative designs to improve reliability of electrical system in underwater vehicle. To reduce the risk and to increase availability of the electrical system, we use the redundancy of the grid structure and power converter. For all design alternatives, we carry out Fault Tree Analysis. Based on the FTA result, we implement RAM simulation to compare the risk and availability for the proposed design alternatives.

최근에 빅 데이터를 활용하여 감성을 측정하는 시도가 활발히 이루어지고 있다. 통신 매체와 SNS의 발달로 기업은 국민의 감성을 파악하고 즉시 대응해야할 필요성이 생겼다. 우리나라의 경제는 대기업에 대한 의존도가 높기 때문에 10대 기업에 대한 감성분석은 의미가 있다고 할 수 있다. 이러한 측면에서 본 연구는 다 범주를 기준으로 구축한 감성사전을 활용하여 우리나라 10대 기업에 대한 감성을 분석하였다. 빅 데이터를 이용하여 감성을 분석한 기존의 선행연구는 감성을 차원으로 분류하는 경향이 있다. 차원적 감성으로 감성을 분류하는 것은 분류의 기준이 학술적으로 증명되었기에 감성 분석에 주로 사용되어 왔지만 전문가 정도의 지식이 있어야 분류할 수 있어 보편적인 감성을 대변하는 데 비효과적이기에 보완이 필요하다고 할 수 있다. 개별 범주적 감성은 이 점을 보완할 수 있는 분류 방식으로 일정 수준의 주관성이 개입되지만 보편적으로 느낄 수 있는 감성을 측정하는데 효과적이다. 따라서 본 연구는 보편적인 감성의 측정을 위해 감성을 차원으로 분류하지 않고 개별 범주로 분류하여 9가지 영역으로 나누었다. 선행 연구에서 추출한 9가지 범주에 해당하는 감성 단어에 기초하여 감성사전을 구축하였으며 감성 단어가 검출된 빈도를 기준으로 감성을 분석했다. 대상 데이터는 2014년 1월부터 2016년 1월까지 우리나라 10대 기업에 대하여 축적된 뉴스 데이터이다. 대상 데이터에서 검출된 감성 단어의 빈도를 기준으로 각 기업에 대한 감성 순위를 나누고 분포를 확인하였다. 기업에 따라서 감성이 다를 수 있는지, 특정 사건이 각 기업에 대한 감성에 영향을 줄 수 있는지 가설을 세우고 검정하였다. 결론적으로, 다 범주 감성 사전을 활용한 감성 분석은 기업 간 비교와 시점 간 비교에 유의한 것으로 나타났다. 본 연구는 빅 데이터에 산재해있는 감성을 국민의 시각으로 측정하는 하나의 대안으로서 의의가 있다.

This study is based on the arguments of Sofia Sarah and concept of 'Sequence Narrative' of Nigel Coates, the founder of Nato. Specifically, this study was conducted under the premise that narrative exhibition space will affect the engagement of viewers. As a result of this study, a method of analyzing a science museum's exhibition space was presented using the narrative structure and the following attributes of visuals: sequence of viewing; spatial tension; spatial pace. The findings are as follows. In terms of 'spatial tension', the exhibiton space with the following progression was more likely to provide viewers with in-depth experience: 'raise of tension' - 'change of pace' - detente.' Although the limited sample doesn't lead to verification of the analysis method and conclusion of its significance, the following was clearly revealed: Exhibiton space that utilizes the structure and attributes of a narrative that provides progression and dramatic tension, as if the viewers were watching a film, is more likely to offer in-depth experience than other spaces. In terms of 'phase transition', the following was revealed: Pace variation around the space with the strongest spatial tension could affect the concentration and engagement of viewers. It suggests the following fact: Spatial rhythm and speed variation in the area with the strongest visual emphasis encourage viewers to feel the spatial changes, maintain their concentration, and continue their viewing.

Purpose - Aviation control, navigation, and aircraft control in the air transportation area are very specialized. Each part is in progress for safety, efficiency, automation, and further. On the other hand co-work among each part including knowledge sharing has been inattentive for many reasons. The purpose of this research is to show how practicians and professionals in the air transportation area perceive the issue of knowledge sharing and to recall the necessity of knowledge sharing in the area. And we try to find ways to activate the knowledge sharing in the area. Research design, data, methodology - For the research, we inquired into whether practicians and professionals think knowledge sharing can effect safe aviation positively or not and what steps are necessary to activate knowledge sharing in the area. We adopted survey method using questionnaires for current practicians and interview for specialists. The survey and interview results were analyzed using regression analysis and AHP method. The interview for specialists and analyzing the results using AHP was to investigate what are the precedence factors to activate the knowledge sharing. Results - First, practicians perceive that knowledge sharing will affect aviation safe positively. Second objective knowledges such as, tower air traffic control procedure of aviation control area, flight principle and structure of aircraft control area, instrument landing system of navigation area, for knowledge sharing of each area were identified. Also the precedence factors such as, knowledge absorbability of personal factor, personal expectation of result of expectation factor, leadership of management of Structure factor, method of knowledge spread of application factor for knowledge sharing were found. Conclusions - Knowledge sharing for practicians and professionals in the aviation area is very important especially from the perspective of safety. However, for various many reasons including the environment of each special area that focusing on their own area, knowledge sharing has not been emphasized. We found that practicians in the area feel that knowledge sharing is necessary and helpful. For it, each practician's active participation is the most important and many ways such as chatting room to share knowledge are to be developed. And the organization culture should be changed to encourage knowledge sharing.

Rheumatoid arthritis, unlike other chronic diseases, causes the patients to experience uncertainty in their daily lives and thus to feel threat on their emotional comfort because of inconsistent and unpredictable symptoms such as pain. Therefore, a theoretical framework is needed for explanation of uncertainty in patients having rheumatoid arthritis. A hypothetical model was constructed on the basis of Mishel's Uncertainty Theory and other literature review. The model included 9 theoretical concepts and 19 paths. Subjects of the study constituted 330 partients who visited outpatient clinics of two university hospitals and one general hospital in Seoul. Self report questionnaires were used to measure the variables affecting uncertainty. Reliability coefficients of these instruments were found Cronbach's Alpha=$.70{\sim}.94$. In data analysis, SAS program and PC-LISREL 8.03 computer program were utilized for descriptive statistics and covariance structure analysis. The results of covariance structure analysis for model fitness were as follows : 1) Hypothetical model showed a good fit to the empirical data : Chi-square($X^2$)=41.81 (df=11, P=.000), Goodness of Fit Index=.974, Root Mean Square Residual=.049, Normed Fit Index=.928, Non Normed Fit Index=.814. 2) For the validity and the parcimony of model, a modified model was constructed by appending 2 paths and deleting 5 paths according to the criteria of statistical significance and meaningfulness. 3) The results of hypothesis testing were as follows : (1) Educational level, event familiarity and severity of illness had a direct effect on uncertainty : Event congruency had both direct and indirect effect on uncertainty : Credible authority and symptom consistency had a nonsignificant direct effect on uncertainty, (2) Illness duration, symptom consistency, and event congruency had a direct effect on severity of illness ; Credible authority had a both direct and indirect effect on severity of illness ; Event congruency had the greatest effect on severity of illness, and event familiarity had a nonsignificant direct effect on severity of illness.

The purpose of this study is to explore types of postpartum depression and to understand the nature and structure of the postpartum depression by using Q-methodological approach. As a way of research, 55 statements concerning postpartum depression were selected through individual interviews with postpartum mothers and literature review. 30 women were chosen as a subject group for the study, with opinions shown in 55 statements divided into 9 scales by forced distribution. PC QUANL Program was used for analysis and Q-factors were analyzed by using principal component analysis. As a result, postpartum depression experience was classified into 5 types. There are "Role-Strain Type", "Unattributional Depression Type", "Psychosomatic Symptoms Type", "Self-Compassion Type", and "Role-Crisis Type". Type I was named "Role-Strain Type", referring to the strain generally experienced by mothers with regard to the new role as a mother and as a social member. Type II was named "Unattributional Depression Type", referring to the symptom experienced by people who were in a state of vanity and a sense of loss. They often break into tears for no specific reasons. In case of Type III, people in a state of "Psychosomatic Symptoms Type" develop physical symptoms after suffering from inherent emotional conflict. Type IV was named "Self-Compassion Type" refers to the symptom shown by those who feel pity for their children and for themselves. And they show inability to cope with the reality properly. Type V was named "Role -Crisis Type", which is experienced by people who have a burden and a severe fear of their own job and their children in their mind, also showing serious conflict with maternal role. Futhermore, it was carried out to examine structure of postpartum depression in terms of degree of depression and adjustment ability. Type I showed mild degree of depression and relatively good adjustment ability. Type II showed broad range of degree in depression and moderate adjustment ability. Type III showed moderate depression and relatively low adjustment ability. Type IV revealed relatively serious degree of depression and the lowest adjustment ability. Type V revealed very serious degree of depression and the lowest adjustment ability. As a result, considering the structure of postpartum depression. Type I is considered to be a normal depression sympton which most mothers generally experience, followed by Type II, Type III, Type IV and Type V, each of which show increasingly worse degree of depression and lower adjustment ability. In conclusion, it seems to be it is necessary to understand distinct symptoms of postpartum depression and to examine the characteristics and structure of those types, so that it could lead to more individual nursing approach.cteristics and structure of those types, so that it could lead to more individual nursing approach.
