연구목적 : 산후 우울증은 10~15%의 산모가 경험하는 흔한 질환이다. 본 예비적 연구의 목적은 산후 우울증과 산전 위험요인으로 가족 적응력 및 응집성과의 관계를 알아보기 위함이다. 방법 : 24명의 산모를 대상으로 출산 전후의 시기에 전향적으로 연구하였다. 임신 36~40주에 산전 위험요인에 대한 질문지, Edinburgh 산후 우울증 척도(EPDS), 가족 적응력-응집성 평가 척도(FACES), Beck 불안 척도(BAI) 등을 시행하였다. 출산 후 4~6주에 구조적 면담으로 미니 국제신경정신인터뷰를 시행하여 산후 우울증을 진단하였으며 산후 위험요인에 대한 질문지, EPDS, BAI 등을 시행하였다. 결과 : 산후 우울증 군과 비 산후 우울증 군을 비교한 결과, 여러 v위험 요인 중 가족 적응력 및 응집성, 산전 우울증상 및 임신 중 기분 변화가 유의한 차이를 보였다. 로지스틱 회귀분석 상 임신 중 기분변화, 낮은 가족 적응력-응집성 평가 척도 총점 및 각 하위 척도 점수가 산후 우울증의 유의한 연관 요인으로 나타났다. 결론 : 본 연구의 결과는 산후 우울증에 있어 낮은 가족 적응력 및 응집성이 유의한 연관성을 가진 요인일 수 있음을 시사한다. 그러나 본 연구는 예비적 연구로 연구 대상 수가 적어 상기 결과가 지지되기 위해서는 대규모 연구가 필요하다.

In digital virtual manufacturing simulation, Digital Human widely used to optimal workplace design, enhancing worker safety in the workplace, and improving product quality. However, the case of ergonomics simulation solutions to support digital human modeling, Optimal DHM (Digital Human Model) data needed to develop and perform DHM will collect information related to the production process. So simulation developer has burden of collecting information. In this study, to overcome the limitations of existing solutions, we proposed the ADAGIO(Automated Digital humAn model development for General assembly usIng Ontology) framework. The ADAGIO framework was developed for DHM ontology to support optimal deployment of digital virtual environment and in order to ensure consistency of simulation components that are required for simulation modeling was made of a library.

We present a method for improving adaptability of Learning from Demonstration (LfD) strategy by combining the LfD and Particle Swarm Optimization (PSO). A trajectory generated from an LfD is modified with PSO by minimizing a fitness function that considers constraints. Finally, the final trajectory is suitable for a task and adapted for constraints. The effectiveness of the method is shown with a target reaching task with a manipulator in three-dimensional space.

The purpose of this study is to investigate (1) the level of childrens' concern and behavior on the environmental preservation, (2) the influential factors related to the two dependent variables above mentioned. The subjects were 286 childrens, in October, 1997, in kwangju. The data obtained were analyzed by Mean, Person's correlation, Stepwise Regression and Path Analysis. The major findings were as follows: 1) The general tendency of the childrens' concern and behavior on the environmental preservation was over the average level. 2) According to the background variables(ie: environment information contracting time, family cohesion and adaptability, biospheric orientation, egoistic orientation), the childrens' concern on the environment was significantly different. 3) According to (1) the background variables(ie: environment information contracting time, family cohesion and adaptability, concern on the environment, biospheric orientation), (2) intermediated variable(ie: concern on the environment), the childrnes' behavior on the environmental preservation was significantly different. 4) The indirect variable of the positive influence for childrnds' behavior on the environment, environment information contracting time. The indirect variable of the negative influence for childrens' the environmental behavior was egoistic orientation.

The finishing process for dies and molds is an important process because it has influence on final quality of products. And it is difficult to automatize finishing process so that the process has depended on expert's skill until now. However, recently a study on development of die automatic finishing machine has been progressed, and actually this machine is applied to fabrication of die. But the research about tooling system is not enough and finishing tool must have high machining efficiency and adaptability of curved surface. So, this study investigated the application of conductive elastic tool which is composed of metal-resin bonded pellet and elastic backing material. The metal-resin bonded pellet is used to finish the surface by conventional mechanical grinding or electro-chemial grinding method. And elastic backing material is used to follow the curved surface. So conductive elastic tool has long lifetime, uniform removal rate and adaptability of curved surface.

Internal marketing has been suggested as the approach for service organizations to be service-and customer-oriented; and the issues of internal service quality has been one of topics widely discussed in the internal marketing literature. The purpose of the current study is to examine the antecedents and consequences of internal service quality which is believed to increase such organizational performances as customer satisfaction, retention and revenue. In consistent with the previous studies in service marketing literatures, the current study identifies several constructs as the antecedents and consequences of internal service quality: management commitment to service quality, employee satisfaction, self-efficacy, and adaptability. The empirical study testing the causal relationships' among the constructs verifies the proposed relationships among the constructs suggested in the current study.

Mechanisms of the robot system should be developed according to the task. In this study, we propose improving adaptability of the robot mechanism with the modularized joint mechanism. Adaptability is the measure of the system ability to cope with change or uncertainty. Modular type joint has been widely used in development of various robots including reconfigurable robots. To build robotic systems more flexibly and quickly with low costs of manufacturing and maintenance, we have designed a modular type joint with one degree of freedom for general purpose. This module is designed to be compact, light-weight and self-controlled. In this design, we consider the kinematics and dynamics properties of the modular type joint.

Distributed planning and decision making can be beneficial from the robustness, adaptability and fault tolerance in multi-robot systems. Distributed mechanisms have not been employed in three dimensional transportation systems namely aerial and underwater environments. This paper presents a distributed cooperation mechanism on multi robot transportation problem in three dimensional environments. The cooperation mechanism is based on artificial capital market, a newly introduced market based negotiation protocol. In the proposed mechanism contributing in transportation task is defined as asset. Each robot is considered as an investor who decides if he is going to invest on some assets. The decision is made based on environmental constraint including fuel limitation and distances those are modeled as capital and cost. Simulations show effectiveness of the algorithm in terms of robustness, speed and adaptability.
