기존의 한국어 형태소 해석은 한국어의 교착어 특성상 다양한 형태론적 모호성을 가진다. 이러한 형태론적 모호성은 많은 구문 모호성을 만들어 내어 올바른 의미를 가지는 파스트리의 선택을 어렵게 한다. 한국어에서 이런 형태론적 모호성의 대부분이 보조용언이나 의존 명사와 관련이 있다. 보조용언이나 의존명사는 주위의 형태소들과 강한 결합 관계를 가지고 있으며, 대부분 자립성이 없는 기능형태소이다. 결합된 형태소들은 문장 내에서 하나의 기능적 역할이나 구문적 역할을 수행한다. 우리는 품사 태깅된 20 만 어절 크기의 말뭉치로부터 이 형태소열을 찾아 이를 3가지 유형으로 분류하였다. 그리고, 이를 구문 형태소로 정의하고 구문 형태소를 구문 분석의 기본 입력 단위로 간주하였다. 본 논문에서는 구문 형태소가 아래와 같은 문제의 해결에 있어서 효율적인 방법임을 제안한다: 1) 형태소 해석의 축소, 2) 구문 해석 도중 불필요한 부분 파스트리의 배제, 3) 구문 모호성의 축소. 마지막으로, 실험 결과를 통해 구문단위 형태소가 형태소 및 구문 모호성을 축소하기 위해 반드시 필요함을 보인다.

Robust motion estimation for human-computer interactions played an important role in a novel method of interaction with electronic devices. Existing pose estimation using a monocular camera employs either ego-motion or exo-motion, both of which are not sufficiently accurate for estimating fine motion due to the motion ambiguity of rotation and translation. This paper presents a hybrid vision-based pose estimation method for fine-motion estimation that is specifically capable of extracting human body motion accurately. The method uses an ego-camera attached to a point of interest and exo-cameras located in the immediate surroundings of the point of interest. The exo-cameras can easily track the exact position of the point of interest by triangulation. Once the position is given, the ego-camera can accurately obtain the point of interest's orientation. In this way, any ambiguity between rotation and translation is eliminated and the exact motion of a target point (that is, ego-camera) can then be obtained. The proposed method is expected to provide a practical solution for robustly estimating fine motion in a non-contact manner, such as in interactive games that are designed for special purposes (for example, remote rehabilitation care systems).

This study examined job satisfaction and relevant variables for multi-cultural family home-visiting educators. The selected study subjects were 192 home-visiting educators who work at Multi-Cultural Family Support Centers in the Seoul, Gyeonggi-do, and Chungcheongnam-do areas. Data analysis was conducted using SPSS ver. 18.0. The main results were as follows. First, the job satisfaction level in multi-cultural family visiting educators stood at 3.29 points, subjects' age, averagely monthly income, marital status, and activity career were shown to influence generally upon job satisfaction, self-efficacy, job stress, and cultural competency. Job satisfaction was high in groups with: a high age, small career, low averagely monthly income, and married. Second, self-efficacy and job stress were big in the job satisfaction of multi-cultural family visiting educators. The same outcome as the existing prior research was indicated. Cultural competency was not significant. Third, an examination of relative influence upon job satisfaction in home visiting educators indicated that the explanation power was 29.0%. Significant influential variables included academic background, marital status, self-regulation, and role ambiguity. Self-regulation was greater for those with lower academic backgrounds and unmarried. Job satisfaction was higher in the lower role ambiguity. Thus, the same outcome as the existing prior research was indicated. Cultural competency wasn't indicated to be significant. This has significance in having shown characteristics of job satisfaction in multi-cultural family visiting educators.

Concept analysis is a strategy that examines the attributes or characteristics of a concept. It is a formal linguistic exercise to determine those defining attributes. The basic purpose of concept analysis is to clarify ambiguous concepts in theory, and to propose a precise operational definition which reflects the theoretical base of the concept. The concept of maternal role is too broad and variable in expression, therefore there has been no authentic definition nor standard opinion for this concept. The purpose of this study is to clarify the concept of maternal role which in turn will help in the development of a theory of maternal role attainment. In order to analyze the concept of maternal role, much effort was extended to look up "maternal role" in various dictionaries and literature, but only a few cases were found which listed this terminology. Consultation on the meaning of "mother" and "role" separately was then done and consequently a definition of "maternal role" was obtained through concept analysis of these two words independently, finding their attributes and unifying them. The attributes of the concept of maternal role which was analyzed based on the steps of concept analysis by Walker & Avant (1988) are : 1) Women who have pregnancies 2) Women who have a child 3) Women who rear a child 4) Expected behavior according to social status 5) Learning through social cultures 6) Social interrelationships. The antecedents of the maternal role are : 1) women who are pregnant and deliver a baby, must keep in contact with their child. 2) Circumstances for childrearing must be provided. 3) Formation of self-concept as mother should be developed, cognitive activity, which is necessary for the nurturing activity, financial support and preparation of childrearing should be provided. And the consequences of the maternal role are : 1) Improvement 2) Changeability 3) Ambiguity 4) Stability Through this concept analysis, the concept of the maternal role is defined as "expected behavior by social interrelationships and learned nurturing behavior through social cultures."

Today, businesses are under rapidly changing environments that are characterized as stopless competition and uncertainty. Under this circumstance, workers are exposed to much stress that is induced by factors such as lots of job burden, responsibility, role conflicts, role ambiguity, interpersonal conflicts, pressure related to job performance and lots of job-related requests. Unlike workers of other industries, those of distribution business may be more exposed to stress because they serve in unique work conditions. Therefore, distribution workers have an accumulate fatigue of their own, suffering from health problems that are stress-induced. Distribution businesses should positively try to identify factors that fall their workers into stress, making those workers less stressful and preventing their negative job performance. Efforts to reduce workers' stress can not only improve their physical and mental health, but also raise business competitiveness. Thus the purpose of this study is to investigate how much distribution workers' job role, interpersonal relations and job environment are influential to their job stress and thereon determine relations between job stress and job performance.

This study presents the Family FIRO model for stepfamily development. The Family FIRO model conceptualizes interactional patterns in stepfamily for dealing with developmental tasks and suggests a method for organizing assessment and for prioritizing treatment strategies. Boundary ambiguity role confusion intergenerational coalition and loyalty conflict lack of relationship commitment and resource management issues of stepfamily constitute the inclusion interaction dimension in The Family FIRO model. While power role negotiation conflict decision making and discipline issues represent the control interaction dimension lack of emotional exchange and open self-disclosure issues are intimacy interaction dimension in the stepfamily. The family FIRO model suggests that stepfamily should attend to the developmental tasks related to inclusion before placing a major emphasis on control issues which in turn should come before emphasis on stepfamily intimacy.

A bubble diagram is understood as a graphic medium which bridges program and plan in architectural design process. The role of a bubble diagram is either to generate or to explain a plan in relation to its program. Despite the explicit role of a bubble diagram in architectural design process, what a bubble diagram indicates exactly is very ambiguous. Here I attempt to reveal the nature of the bubble diagram more sharply. My main argument is that the ambiguity of a bubble diagram results from the fact that it is used to range two different types of representational formats. Reviewing the theories of shape recognition and shape representations in vision science, I will also argue that the procedural description of architectural design process should be criticized and that the focus of design method research has to be shifted into the representational format of form description in architectural design process.

Despite advances in medicine and preventive strategies, fewer than 1 in 5 people with hypertension have the problem under control. This could partly be due to gaps in fully elucidating the etiology of hypertension. Genetics and conventional lifestyle risk factors, such as the lack of exercise, unhealthy diet, excess salt intake, and alcohol consumption, do not fully explain the pathogenesis of hypertension. Thus, it is necessary to revisit other suggested risk factors that have not been paid due attention. One such factor is psychosocial stress. This paper explores the evidence for the association of psychosocial stressors with hypertension and shows that robust evidence supports the role of a chronic stressful environment at work or in marriage, low socioeconomic status, lack of social support, depression, anxiety, post-traumatic stress, childhood psychological trauma, and racial discrimination in the development or progression of hypertension. Furthermore, the potential pathophysiological mechanisms that link psychosocial stress to hypertension are explained to address the ambiguity in this area and set the stage for further research.
